(Embodiment 1)
(1) Overview The power supply stand 1 (see FIG. 1A) according to the present embodiment is a device for supplying power to a power supply target 92 (see FIG. 3). In the present disclosure, "power supply targets" include, for example, various home appliances such as vacuum cleaners, air purifiers, and personal computers, and mobile terminals such as tablet terminals, smartphones, and mobile phones, or chargers for mobile terminals. In other words, the power supply target 92 receives power from the power supply station 1 .

The power supply stand 1 is used while being placed on an installation surface 91 (see FIG. 3), which is, for example, the floor of a room in a house. As shown in FIGS. 1A and 1B, the power supply stand 1 includes a portable main body part 3 having a power supply part 2 for supplying power to a power supply target 92, and a support part 4 that supports the main body part 3. Be prepared. The support part 4 supports the main body part 3 so that the main body part 3 stands on the installation surface 91 in a state where it is placed on the installation surface 91.

That is, the power supply stand 1 according to the present embodiment is a power supply device in which at least the main body 3 is self-supporting and portable, and the user 93 (see FIG. 3) can freely carry the power supply stand 1 and place it on the installation surface 91. Can be installed in any position. Thereby, for example, in an environment such as a living room of a house, it is possible to freely arrange the power supply source to the power supply target 92 such as a mobile terminal. Moreover, the power supply stand 1 is installed such that the main body 3 having the power supply section 2 is supported by the support section 4 and stands on the installation surface 91. Therefore, in the power supply stand 1, problems such as failure of the power supply part 2 may occur due to the power supply part 2 being stepped on by a person's foot or liquid being splashed on the power supply part 2 when liquid is spilled on the installation surface 91. It has the advantage of being difficult.

(2) Details Hereinafter, the configuration of the power supply stand 1 according to the present embodiment will be described in detail with reference to FIGS. 1A to 5.

As described above, the power supply stand 1 includes the portable main body portion 3 and the support portion 4. The main body 3 includes a power supply section 2 for supplying power to a power supply target 92 (see FIG. 3). The support part 4 supports the main body part 3 so that the main body part 3 stands on the installation surface 91 (see FIG. 3) in a state where it is placed on the installation surface 91 (see FIG. 3). The term "standing state" as used in the present disclosure means a state in which it is placed in a specific position, such as on a floor surface. That is, the support portion 4 is not movable on the installation surface 91 using casters or the like, but is installed with a predetermined position on the installation surface 91. Therefore, although the power supply stand 1 according to the present embodiment is portable, it is used in a free-standing state on an installation surface 91 consisting of, for example, the floor of a room in a house.

In the following, the direction perpendicular (orthogonal) to the horizontal plane when the power supply stand 1 is placed on the installation surface 91, which is the floor, is referred to as the "up-down direction", and the downward direction (vertical) in the up-down direction is referred to as the "downward direction". ”. In addition, in the power supply stand 1, the surface on which the plurality of connection ports 21 to 24 (described later) of the power supply unit 2 are provided is the front side, and the right side when looking at the power supply stand 1 from the front is the "right side", and the left side is the "right side". This will be explained as "left side". The arrows indicating the "vertical direction", "front/backward direction", and "horizontal direction" in the drawings are only shown for the purpose of explanation and have no substance. However, these directions are not intended to limit the usage direction (installation direction) of the power supply stand 1. For example, the “front” defined here may be the right side or the left side when viewed from the user 93 when the power supply stand 1 is actually used.

The power supply unit 2 has a plurality of connection ports 21 to 24 for connecting power supply targets 92, respectively. The plurality of connection ports 21 to 24 are arranged vertically (vertically). In this embodiment, as an example, four connection ports 21 to 24 are arranged on the front surface 301 of the main body 3 so as to be vertically aligned in a row.

In this embodiment, each of the upper two connection ports 21 and 22 among the four connection ports 21 to 24 is a USB receptacle into which a USB (Universal Serial Bus) plug can be inserted and connected. Each of these two connection ports 21 and 22 is configured to output a DC voltage of 5 [V] to the power supply target 92 through a USB plug. Furthermore, each of the lower two connection ports 23 and 24 among the four connection ports 21 to 24 is an outlet into which an A type outlet plug having a pair of blades can be inserted and connected. Each of these two connection ports 23 and 24 is configured to output an AC voltage of 100 [V] to the power supply target 92 through an outlet plug. That is, the power supply unit 2 is configured to be able to output both DC power and AC power, and outputs DC power or AC power from one of the four connection ports 21 to 24 depending on the power supply target 92. .

The “power supply unit” in the present disclosure only needs to have a function of supplying at least one of AC power and DC power to the power supply target 92, and may be a power supply unit 92 such as a USB receptacle or an outlet. The configuration is not limited to having a terminal for electrically connecting. For example, the power supply unit 2 may be a power supply port for non-contact power supply using a magnetic resonance method or an electromagnetic induction method.

The vertical dimension (vertical direction) of the main body part 3 is larger than both the longitudinal dimension and the horizontal dimension of the main body part 3. That is, the main body portion 3 is formed in a so-called vertically elongated shape that is elongated in the vertical direction. In this embodiment, the lower end of the main body 3 is fixed to the support 4 by, for example, adhesive or screws.

Further, the main body portion 3 includes a fixed portion 31 and a movable portion 32. The fixed part 31 is fixed to the support part 4. The movable part 32 is movable relative to the fixed part 31 in the up-down direction (vertical direction). That is, the main body part 3 has a movable part 32 that moves in the vertical direction, as shown in FIGS. 1A and 1B.

Specifically, the fixed part 31 has a base part 311 and a pole part 312. The base portion 311 is fixed to the support portion 4. The base portion 311 is a resin molded product having a triangular shape when viewed from the side, and the front surface thereof is inclined so that the dimension in the front and back direction of the base portion 311 decreases as it approaches the upper end. The pole portion 312 is a portion extending upward from the upper surface of the base portion 311. The pole portion 312 is a rectangular parallelepiped-shaped resin molded product that is elongated in the vertical direction and flat in the front-back direction. Here, the base portion 311 and the pole portion 312 are integrated.

The movable part 32 includes a case 321 and a back panel 322. The case 321 is a rectangular parallelepiped-shaped resin molded product that is elongated in the vertical direction and flat in the front-back direction. As shown in FIGS. 2A and 2B, the case 321 is located directly above the pole part 312 so as to have a sense of unity with the pole part 312 of the fixing part 31 in appearance, and is also connected to the pole part 312 in a plan view. They are configured in the same shape. The back panel 322 is a plate-shaped resin molded product that is elongated in the vertical direction and curved so that the central portion in the left-right direction is convex toward the rear. The case 321 is fixed to the front surface of the back panel 322 at a position above the center in the vertical direction. The back panel 322 is held by the fixed part 31 via a slide mechanism so as to be movable in the vertical direction along the rear surface of the fixed part 31. The slide mechanism is realized using, for example, a telescopic mechanism such as a telescopic structure in which a plurality of cylindrical bodies having different opening areas are stacked together, a slide rail, or the like.

With the above configuration, as the back panel 322 moves relative to the fixed part 31 as indicated by arrow A1 in FIG. 1B, the case 321 moves together with the back panel 322 in the vertical direction. That is, when the back panel 322 moves upward, the case 321 moves away from the pole section 312, and when the back panel 322 moves downward, the case 321 moves toward the pole section 312. Therefore, when looking at the main body 3 as a whole, when the movable part 32 moves in the vertical direction, the main body 3 expands and contracts so that the vertical dimension of the main body 3 changes.

1A shows a state where the movable part 32 is located at the lower end of the movement range, that is, a "shortened state" in which the main body part 3 is contracted, and FIG. 1B shows a state where the movable part 32 is located at the upper end of the movement range, In other words, it shows an "extended state" in which the main body portion 3 is extended. In other words, when the main body 3 is in the shortened state, the height of the power supply stand 1 is the minimum, and when the main body 3 is in the extended state, the height of the power supply stand 1 is the maximum. In this embodiment, as an example, the height of the power supply stand 1 is 600 [mm] in the shortened state and 850 [mm] in the extended state. When the main body part 3 is in the shortened state, the entire rear surface of the case 321 and the fixing part 31 is covered by the back panel 322. Therefore, the front surface of the case 321 and the fixing section 31 constitutes the front surface 301 of the main body section 3, and the rear surface of the back panel 322 constitutes the rear surface 302 of the main body section 3.

Here, the power feeding section 2 is provided in the movable section 32 of the fixed section 31 and the movable section 32 that constitute the main body section 3 . Specifically, the power supply section 2 is provided on the front surface of the case 321 of the movable section 32 (the front surface 301 of the main body section 3). That is, the power feeding section 2 is arranged in the main body section 3 at a position above at least the fixing section 31 . By moving the movable part 32 in the vertical direction, the height of the power feeding part 2 from the installation surface 91 changes. In this embodiment, the power supply unit 2 has a plurality of plug-in connection ports 21 to 24, so that the power supply target 92 has a plurality of connection ports 21 to 24 provided on the front surface 301 of the main body 3 The plug will be inserted from the front.

The support part 4 is a flat member fixed to the lower surface of the fixed part 31 (base part 311). In other words, the base portion 311 is supported by the support portion 4 so as to protrude upward from the upper surface of the support portion 4 . In this embodiment, the front end of the support part 4 is set larger in the left-right direction than the rear end of the support part 4, and the support part 4 has a T-shape in plan view. .

Here, the projection point of the center of gravity of the main body part 3 onto the upper surface of the support part 4 is located between the center of the upper surface of the support part 4 and the rear end in the front-rear direction. That is, the projection point of the center of gravity of the main body part 3 in the vertical direction is set not at the center of the upper surface of the support part 4 but at a position closer to the rear end. As a result, even if the power supply stand 1 were to fall, it is unlikely that the power supply stand 1 would fall toward the front surface 301 side of the main body 3 where the power supply unit 2 is provided, that is, toward the front.

The power supply stand 1 according to the present embodiment further includes a power supply cord 5 (see FIG. 3) for supplying power to the power supply unit 2. The main body part 3 has a power receiving part 6 for electrically connecting the power supply cord 5. Similar to the power feeding section 2, the power receiving section 6 is provided in the movable section 32 of the fixed section 31 and the movable section 32 that constitute the main body section 3. That is, the movable part 32 has the power receiving part 6 to which the power supply cord 5 is electrically connected.

Here, the power receiving section 6 is provided in the case 321 of the movable section 32, similarly to the power feeding section 2. Further, the power receiving section 6 is arranged on the front surface 301 of the main body section 3 so as to be vertically aligned with the four connection ports 21 to 24 of the power feeding section 2. The power receiving unit 6 is arranged further below the lowest connection port 24 among the four connection ports 21 to 24. Specifically, a slightly depressed portion of the front surface of the case 321 below the connection port 24 constitutes the power receiving section 6 . The power receiving section 6 has a pair of power receiving terminals 61.

By contacting (connecting) a pair of terminals 51 (see FIG. 4A) of the power supply cord 5 (described later) to the pair of power reception terminals 61, the power supply cord 5 is electrically connected to the power reception unit 6. Since the end of the power supply cord 5 opposite to the pair of terminals 51 is connected to an external power supply, power is supplied from the external power supply to the power receiving unit 6 via the power supply cord 5 . In this embodiment, an AC voltage of 100 [V] is applied to the power receiving unit 6 from an external power supply.

A pair of power receiving terminals 61 of the power receiving section 6 are electrically connected to four connection ports 21 to 24 of the power feeding section 2 within the case 321. In this embodiment, each of the two upper connection ports 21 and 22 is a USB receptacle, so the power supply unit 2 includes an AC/DC conversion unit 20 (see FIG. 5) that converts AC voltage to DC voltage. are doing. An AC/DC conversion unit 20 is connected between the power receiving unit 6 and the connection ports 21 and 22. That is, an AC voltage of 100 [V] from an external power supply to the power receiving unit 6 is converted into a DC voltage of 5 [V] by the AC/DC conversion unit 20 and supplied to the connection ports 21 and 22.

The power supply stand 1 configured as described above is used, for example, as shown in FIG. 3, in a state where it stands on an installation surface 91 that is the floor surface of a room in a house. In the example of FIG. 3, in a scene where a user 93 is sitting on a sofa 94 and using a tablet terminal that is a power supply target 92, power is supplied to the power supply target 92 at the power supply stand 1. In the example of FIG. 3, the topmost connection port 21 among the four connection ports 21 to 24 is used, and DC power is supplied from the power supply section 2 to the power supply target 92.

That is, in FIG. 3, the power supply stand 1 is installed near the sofa 94 on the installation surface 91. In other words, since at least the main body 3 of the power supply stand 1 is portable, the power supply stand 1 can be installed at any position on the installation surface 91 depending on the layout of the furniture, etc. , it is easy to install the power supply stand 1 near the user 93. As a result, the user 93 can freely arrange the source of power supply to the power supply target 92 in an environment such as a living room of a house. Moreover, since the power supply stand 1 is freestanding, the area occupied by the power supply stand 1 on the installation surface 91 can be kept small, and the power supply stand 1 is less likely to get in the way when the user 93 moves around the room. . In addition, in the power supply stand 1, malfunctions such as failure of the power supply unit 2 may occur due to the power supply unit 2 being stepped on by a person's foot or liquid being splashed on the power supply unit 2 when liquid is spilled on the installation surface 91. Hateful.

Here, in the example of FIG. 3, since the main body portion 3 is in the shortened state, the height H1 of the power feeding stand 1 is 600 [mm]. In this state, the lower end of the power supply section 2 (the lowest connection port 24) may interfere with the armrest of the sofa 94. In order to avoid interference between the power supply section 2 and the armrest of the sofa 94, the movable section 32 may be moved upward until the height H1 of the power supply stand 1 becomes approximately 700 [mm]. As a result, the lower end of the power supply section 2 (the lowest connection port 24) is located above the armrests of the sofa 94, and interference between the power supply section 2 and the armrests of the sofa 94 can be avoided. Furthermore, in this embodiment, as shown in FIG. 3, the direction in which the power supply cord 5 is pulled out from the main body 3 is downward. Therefore, the power supply cord 5 is pulled out from the main body part 3 along the front surface 301 of the main body part 3, and the power supply cord 5 is pulled out from the main body part 3 along the front surface 301 of the main body part 3. Hard to get in the way.

Although FIG. 3 shows an example in which the power supply stand 1 is installed near the sofa 94, this is not intended to limit the manner in which the power supply stand 1 is used. For example, the power supply stand 1 may be installed near a bed, a low table, a kitchen counter, etc., or at a position away from furniture.

By the way, the power supply cord 5 has a pair of terminals 51 and a connector housing 52, as shown in FIGS. 4A and 4B. A pair of terminals 51 are provided at one end of the power supply cord 5 . Connector housing 52 holds a pair of terminals 51. In this embodiment, the connector housing 52 is a resin molded product formed into a rectangular parallelepiped shape, and the pair of terminals 51 are provided on one surface of the connector housing 52. An outlet plug is provided at the end of the power supply cord 5 opposite to the connector housing 52. Therefore, for example, the outlet plug of the power supply cord 5 is connected to an external power source such as an outlet installed on the wall of the living room, and the pair of terminals 51 are connected to the pair of power receiving terminals 61 of the power receiving section 6. As a result, power is supplied from the external power source to the power receiving unit 6.

In addition, as shown in FIGS. 4A and 4B, the power feeding stand 1 mechanically couples the power feeding cord 5 to the power receiving unit 6 by magnetic force while the power feeding cord 5 is electrically connected to the power receiving unit 6. It further includes a coupling structure 7. The coupling structure 7 includes a pair of metal plates 71 and a pair of magnets 72. The pair of metal plates 71 are embedded around the pair of terminals 51 in the connector housing 52. The pair of magnets 72 are embedded around the pair of power receiving terminals 61 in the power receiving section 6 . The pair of metal plates 71 are made of a ferromagnetic material such as iron, for example, and are attracted to the pair of magnets 72 by the magnetic force of the pair of magnets 72 when brought close to the pair of magnets 72 . When the connector housing 52 is attracted to the power receiving section 6, the pair of terminals 51 are electrically connected to the pair of power receiving terminals 61.

Moreover, the power supply stand 1 according to the present embodiment further includes a detection section 11 and a stop section 12, as shown in FIG. The detection section 11 detects the attitude of the main body section 3. The stop unit 12 stops supplying power from the power supply unit 2 to the power supply target 92 based on the attitude of the main body 3 detected by the detection unit 11 . In this embodiment, the detection section 11 and the stop section 12 are housed in a case 321 of the movable section 32 in the main body section 3 .

The detection unit 11 is, for example, a tilt sensor that detects the tilt of the main body 3 with respect to the vertical direction using an acceleration sensor, a gyro sensor, or the like. The stop unit 12 is, for example, a switch (including a semiconductor switch and a relay) connected between the power receiving unit 6 (a pair of power receiving terminals 61) and the power feeding unit 2. When the detection unit 11 detects a tilt of the main body 3 that exceeds a predetermined value, the stop unit 12 is turned off, thereby cutting off the connection between the power receiving unit 6 (a pair of power receiving terminals 61) and the power feeding unit 2. In this configuration, when the main body 3 falls or is about to fall, the detection unit 11 detects the inclination of the main body 3 and operates the stop unit 12. Thereby, it is possible to suppress the main body part 3 from falling over while the power feeding part 2 is still energized.

(3) Modifications The power supply stand 1 according to the first embodiment is only one of various embodiments of the present disclosure. The power supply stand 1 according to the first embodiment can be modified in various ways depending on the design and the like, as long as the purpose of the present disclosure can be achieved.

That is, the fixing structure 41 does not completely fix the support part 4 to the installation surface 91 by, for example, embedding or adhering, but temporarily fixes the main body part 3 to the installation surface 91. By temporarily fixing the support part 4 with the fixing structure 41, the power supply stand 1A is less likely to fall.

In the example of FIG. 6A, the fixing structure 41 includes a pair of holes 411 formed in the support part 4 and a pair of bolts 412. Each of the pair of holes 411 is a hole that is formed at each end in the left-right direction of the front end portion of the support portion 4 and is open toward the outside in the left-right direction. As shown in FIG. 6B, the pair of bolts 412 pass through the support part 4 in the thickness direction (vertical direction) through the pair of holes 411, and are fitted into screw holes (nuts) provided in the installation surface 91. (Threaded together), the support part 4 is fixed at a fixed position on the installation surface 91.

The fixing structure 41 may be any structure that temporarily fixes the power supply stand 1A, so it is not limited to the examples shown in FIGS. It may also be realized by Further, as will be described in detail in Embodiment 2, the fixing structure 41 for fixing the supporting part 4 at a fixed position on the installation surface 91 can also be used by having a fixture such as a desk 95 (see FIG. 10A) step on the supporting part 4. is realized.

(3.2) Second Modified Example As shown in FIG. 7, the power feeding stand 1B according to the second modified example of Embodiment 1 has the power feeding stand 1B according to Embodiment 1 in that the main body part 3 has a top plate part 33. It is different from stand 1.

The top plate section 33 is provided at the upper end of the main body section 3. In the example of FIG. 7, the top plate part 33 is a resin molded product formed in a disk shape, and is fixed to the upper end of the front surface of the back panel 322 so as to be located above the case 321. Here, the top plate section 33 protrudes further forward from the front surface 301 of the main body section 3 where at least the power supply section 2 is provided.

With this configuration, even if the power feeding stand 1B falls toward the front, that is, the front surface 301 side of the main body 3 where the power feeding section 2 is provided, the top plate 33 serves as a support and the front surface of the main body 3 A gap is ensured between 301 and installation surface 91. Therefore, even if the power supply stand 1B falls forward, the USB plug or outlet plug connected to the power supply unit 2 is less likely to be damaged by hitting the installation surface 91.

Furthermore, in the example of FIG. 7, the top plate section 33 also functions as a stand for a portable terminal such as a tablet terminal, a smartphone, a mobile phone, etc., which is a power supply target 92 electrically connected to the power supply section 2. That is, it is possible to place, for example, a mobile terminal being charged on the top plate portion 33.

In the example of FIG. 8, the battery 13 is housed in the base portion 311 of the fixed portion 31. The battery 13 is, for example, a secondary battery, and is attached to the main body 3 in a removable state from the main body 3 (base 311). Therefore, by charging the battery 13 that has been removed from the main body 3, the battery 13 can be used repeatedly. The power supply stand 1C includes a discharge circuit that supplies power output from the battery 13 to the power supply unit 2. The discharge circuit includes, for example, an inverter that converts the DC voltage output from the battery 13 into AC voltage. In addition, in the example of FIG. 8, the power receiving unit 6 is omitted, and a connection port 25 similar to the connection ports 23 and 24 is located at the position where the power receiving unit 6 was placed in the power feeding stand 1 according to the first embodiment. It is provided.

However, the present invention is not limited to the example described above, and the power supply stand 1C may include a power receiving section 6 for electrically connecting the power supply cord 5, similar to the power supply stand 1 according to the first embodiment.

Furthermore, in the first embodiment, the main body part 3 is fixed to the lower end part of the main body part 3 and the support part 4, but the structure is not limited to this, and the main body part 3 may be configured to be separable from the support part 4. Even in this case, the main body part 3 is supported by the support part 4, so that the power supply stand 1 can stand on the installation surface 91. Further, the lower end portion of the main body portion 3 may be formed integrally with the support portion 4.

Furthermore, the detection section 11 and the stop section 12 may be integrated. For example, the detection section 11 and the stop section 12 may be realized by a fall switch using a photo sensor, a metal ball, or the like. In this case, the fall switch detects the posture (upright/fallen) of the main body 3 and stops the supply of power from the power supply unit 2 when it detects that the main body 3 falls.

Furthermore, the power supply stand 1 is not limited to residential use, and may be used, for example, in non-residential facilities such as stores, offices, and factories. Furthermore, the power supply stand 1 is not limited to a configuration that is used indoors such as a living room, but may be used outdoors. When used outdoors, the installation surface 91 may be, for example, a terrace, a wooden deck, or the ground. When used outdoors, the power supply stand 1 preferably has an appropriate waterproof structure.

In addition, the power supply section 2 (connection ports 23, 24) is not limited to an outlet for AC 100 [V] without a grounding electrode, but also an outlet for AC 200 [V] with a grounding electrode, for example. Alternatively, it may be a DC outlet. Furthermore, the power supply unit 2 (connection ports 23, 24) is not limited to an A-type outlet, but also a B-type or C-type outlet to which a plug with a pin-shaped plug can be connected.

Furthermore, the power feeding unit 2 is not limited to a configuration having four connection ports 21 to 24, but may have a configuration having one, two, or three connection ports, or a configuration having five or more connection ports. It may be.

Further, the end of the power supply cord 5 opposite to the connector housing 52 is not limited to an outlet plug connectable to an outlet, and may be provided with, for example, a harness plug. The harness plug is connected to an external power source such as a joint box provided under the floor in a raised floor (double floor) where wiring is laid under the floor. As a result, power is supplied from an external power source such as a joint box to the power receiving unit 6 via the power supply cord 5.

Further, a plurality of power supply stands 1 may be provided. In this case, the plurality of power supply stands 1 connected to the installation surface 91 may be electrically connected by feed wiring.

(Embodiment 2)
As shown in FIG. 9, the power supply stand 1D according to the present embodiment has a main body 3 that does not include a relatively movable fixed portion 31 (see FIG. 1A) and a movable portion 32 (see FIG. 1A). , is different from the power supply stand 1 according to the first embodiment. Hereinafter, the same reference numerals will be used for the same configurations as in Embodiment 1, and the description will be omitted as appropriate.

The main body 3 of the power supply stand 1D includes a first block 34, a second block 35, and a third block 36. The first block 34 corresponds to the fixing part 31 in the first embodiment and is fixed to the support part 4. The first block 34 is a rectangular parallelepiped-shaped resin molded product that is elongated in the vertical direction and flat in the front-back direction. The second block 35 corresponds to the case 321 in the first embodiment, and is a rectangular parallelepiped-shaped resin molded product that is elongated in the vertical direction and flat in the front-back direction. The third block 36 corresponds to the back panel 322 in the first embodiment, and is a plate-shaped resin molded product that is elongated in the vertical direction and curved so that the center portion in the left-right direction is convex rearward. . The first block 34 and the second block 35 are fixed to the front surface of the third block 36 so that the second block 35 is located above the first block 34 .

In this embodiment, the power receiving unit 6 (see FIG. 11A) is provided in the first block 34. More specifically, the power receiving section 6 is provided on the right side surface of the lower end of the first block 34 . Therefore, the power supply cord 5 is pulled out from the lower end of the first block 34, as shown in FIG. On the other hand, the power supply section 2 is provided in the second block 35.

Here, the main body part 3 further has a constricted part 37 in a part of the vertical direction (vertical direction), the size of which is smaller in the front-back direction or the left-right direction than other parts of the main body part 3 . In the present embodiment, a gap of a predetermined width is provided between the upper surface of the first block 34 and the lower surface of the second block 35, and in the third block 36, a portion corresponding to this gap is located at the constricted portion 37. Configure. That is, in the main body portion 3, the dimension in the front-rear direction is smaller than other portions in the gap between the first block 34 and the second block 35, so this portion constitutes the constriction portion 37.

The power supply stand 1D configured as described above is used, for example, as shown in FIG. 10A, in a state where it stands on an installation surface 91 that is a floor surface of a room in a house. In the example of FIG. 10A, it is assumed that a power supply stand 1D is installed near a desk 95, which is a fixture, and a user sitting on a chair 96 uses the power supply stand 1D. The "fixtures" in the present disclosure are not limited to the desk 95, but include, for example, the chairs 96, storage shelves, partitions, and the like. In the example of FIG. 10A, the desk 95 is installed next to the wall 97, and the power supply stand 1D is placed between the desk 95 and the wall 97 with the rear surface 302 of the main body 3 (see FIG. 11A) facing the wall 97. It is installed in the gap.

Here, the support part 4 of the power supply stand 1D is stepped on by the leg part 952 of the desk 95. Thereby, the support portion 4 is fixed (temporarily fixed) at a fixed position on the installation surface 91, so that the power supply stand 1D is less likely to fall. That is, the support part 4 itself functions as a fixing structure for fixing the support part 4 at a fixed position on the installation surface 91. In this embodiment, the thickness of the support part 4 is set smaller (thinner) than in the first embodiment in order to allow the fixtures such as the desk 95 to step on the support part 4 in this way.

Further, as described above, the power receiving unit 6 (see FIG. 11A) is provided on the right side surface of the lower end of the first block 34. However, the power receiving unit 6 may be provided on the front or left side of the first block 34. That is, the power receiving unit 6 is arranged on the front surface 301 of the main body 3 and at least one of both sides in the left and right direction (in the present embodiment, the right side). Therefore, the power supply stand 1D can be installed next to the wall 97 with the rear surface 302 of the main body 3 facing the wall 97 while avoiding interference between the power supply cord 5 and the wall 97. Moreover, the power supply cord 5 is pulled out from the main body 3 along the wall 97, so that the power supply cord 5 is less likely to get in the way.

Here, the height H2 of the power supply stand 1D is, for example, 850 [mm]. On the other hand, the height H11 of the upper surface 953 of the top plate 951 of the desk 95 is generally about 700 [mm]. Therefore, as shown in FIG. 10A, at least a portion of the main body 3 protrudes upward from the upper surface 953 of the top plate 951 of the desk 95. In other words, the main body 3 has a protrusion that protrudes upward from a plane that includes the upper surface 953 of the fixture (desk 95) installed on the installation surface 91. In this embodiment, the position of the top plate 951 matches the position of the constriction part 37 of the main body part 3 in the vertical direction, and the end of the top plate 951 is inserted between the first block 34 and the second block 35. It will be done. That is, the constricted portion 37 is sandwiched between the top plate 951 and the wall 97. Therefore, the second block 35 constitutes a protrusion. Here, the power feeding section 2 is provided in the protrusion (second block 35). Therefore, interference between the power supply unit 2 and the fixture (desk 95) can be avoided, and the usability of the power supply unit 2 is improved.

Moreover, FIG. 10B shows an example of use of a power supply stand 1E according to a modification of the second embodiment. This power supply stand 1E is installed below the top plate 951 of the desk 95. The height H12 of the lower surface of the top plate 951 of the desk 95 is generally 620 [mm] or more. Therefore, the height H3 of the power supply stand 1E is set to 600 [mm] as an example. Thereby, the power supply stand 1E can be installed so as to fit under the top plate 951, as shown in FIG. 10B.

By the way, as described above, the power supply stand 1D according to the present embodiment is intended to be installed next to the wall 97 with the rear surface 302 of the main body 3 facing the wall 97. It adopts two configurations.

As a first configuration, as shown in FIG. 11A, the power supply section 2 is provided on the front surface 301 of the main body section 3, and the amount of rearward protrusion of the support section 4 from the rear surface 302 of the main body section 3 is as follows. This is smaller than the amount of forward protrusion of the support section 4 from the front surface 301 of the main body section 3 . Specifically, the amount of rearward protrusion of the support portion 4 from the rear surface 302 of the main body portion 3 is set to several centimeters or less. In this embodiment, as shown in FIG. 11A, the rear surface 302 of the main body part 3 and the rear surface of the support part 4 are flush with each other, so the amount of rearward protrusion of the support part 4 from the rear surface 302 of the main body part 3 is It is 0 [cm]. Therefore, when the power supply stand 1D is installed next to the wall 97, the gap between the rear surface 302 of the main body 3 and the wall 97 can be kept small, and the power supply stand 1D can be stably installed.

As a second configuration, as shown in FIG. 11B, the power supply section 2 is provided on the front surface 301 of the main body section 3, and the main body section 3 is provided at a portion behind the power supply section 2 on the rear surface 302 of the main body section 3. It further has a pressure receiving part 38 that protrudes rearward. That is, the pressure receiving part 38 is provided on the back side of the power feeding part 2 in the main body part 3 and protrudes rearward from the rear surface 302 of the main body part 3. Therefore, even if a gap is created between the rear surface 302 of the main body part 3 and the wall 97 by the thickness of the baseboard 98, for example, this gap can be filled with the pressure receiving part 38.

Here, in this embodiment, the amount of protrusion of the pressure receiving part 38 from the rear surface 302 of the main body part 3 is variable. As an example, the pressure receiving part 38 is connected to the main body part 3 with a "screw" like an adjuster bolt. Therefore, by rotating the pressure receiving part 38, the amount of protrusion of the pressure receiving part 38 from the rear surface 302 of the main body part 3 changes from "L1" shown in FIG. 11A to "L2" shown in FIG. 11B (L2>L1 ). The amount of protrusion of the pressure receiving portion 38 is adjusted depending on the thickness of the baseboard 98, for example.

By the way, the height of the power supply stand 1D is, as mentioned above, 850 [mm] as an example, but is not limited to this configuration and can be changed as appropriate. However, considering that the power supply stand 1D is installed near a fixture such as the desk 95, the lower end of the power supply unit 2 is at a height of 720 [mm] or more from the installation surface 91. It is preferable that the upper end of the power feeding section 2 be at a height of 850 [mm] or less from the installation surface 91. Similarly, if the power supply stand 1E fits under the top plate 951 of the desk 95, the upper end of the power supply unit 2 is preferably at a height of 600 [mm] or less from the installation surface 91. Furthermore, when the power supply stand 1E is installed near the sofa 94 (see FIG. 3) as described in Embodiment 1, the lower end of the power supply unit 2 is installed in order to avoid interference with the armrest. It is preferable that the height is 550 [mm] or more from the surface 91.

The configuration of Embodiment 2 (including modifications) can be applied in appropriate combination with the configuration described in Embodiment 1 (including modifications).

(Embodiment 3)
As shown in FIGS. 12A and 12B, the power supply stand 1F according to the present embodiment is different from the power supply stand 1D according to the second embodiment in the arrangement of the batteries 13 and the like. Hereinafter, the same reference numerals will be used for the same configurations as in the second embodiment, and the description will be omitted as appropriate.

That is, the power supply stand 1F is the same as the power supply stand 1C (see FIG. 8) according to the third modification of the first embodiment in that it includes the battery 13. Due to the configuration including the battery 13, the power supply stand 1F is capable of supplying power from the power supply unit 2 to the power supply target 92 without receiving power from an external power supply through the power supply cord 5 (see FIG. 9). . Furthermore, the power receiving section 6 is omitted in the power feeding station 1F.

The power supply stand 1F according to this embodiment further includes a charging circuit 101. The battery 13 is a secondary battery (storage battery) that is charged by the charging circuit 101. That is, in this embodiment, the battery 13 is charged by the charging circuit 101 of the power supply station 1F, so that the battery 13 can be used repeatedly. The charging circuit 101 is built into the first block 34 of the main body 3, for example. Charging circuit 101 is electrically connected to at least battery 13 and non-contact power receiving circuit 104, which will be described later.

The power supply stand 1F further includes a discharge circuit 102 that supplies power output from the battery 13 to the power supply unit 2. The discharge circuit 102 includes, for example, an inverter that converts the DC voltage output from the battery 13 into an AC voltage. The discharge circuit 102 is built into the first block 34 of the main body 3, for example. Discharge circuit 102 is electrically connected to at least battery 13 and power supply unit 2 .

By the way, in this embodiment, the power supply unit 2 can supply power to the power supply target 92 even while the battery 13 is being charged. Specifically, the discharging circuit 102 is also electrically connected to the charging circuit 101 and supplies not only the power output from the battery 13 but also the power output from the charging circuit 101 to the power supply unit 2. is also possible. As a result, even while the battery 13 is being charged, the power output from the charging circuit 101 can be sent to the power supply section 2 through the discharging circuit 102, and power can be supplied from the power supply section 2 to the power supply target 92. Become. In this case, even when the battery 13 is fully charged, the charging circuit 101 continues to operate, so the charging circuit 101 continuously supplies a small current to the battery 13 by, for example, trickle charging.

Further, the power supply stand 1F according to the present embodiment further includes a remaining amount display section 103. The remaining capacity display unit 103 is realized using, for example, an LED (Light Emitting Diode) or the like, and displays the remaining capacity of the battery 13. The remaining capacity of the battery 13 in the present disclosure is the relative remaining capacity (RSOC) of the remaining capacity (RC: Remaining Capacity) divided by the battery 13's full charge capacity (FCC: Full Charge Capacity). It is. The relative remaining capacity (RSOC) in the present disclosure is synonymous with the state of charge (SOC). As an example, the remaining capacity display section 103 displays the remaining capacity of the battery 13 by changing the lighting state (on/off, blinking pattern, emission color, etc.) according to the remaining capacity of the battery 13.

It is preferable that such a remaining amount display section 103 is arranged around the power supply section 2, that is, near the power supply section 2, so that it can be easily seen by the user 93 who uses the power supply section 2. In the example of FIGS. 12A and 12B, the remaining amount display section 103 is arranged below the four connection ports 21 to 24 of the power supply section 2 in the second block 35. Further, the remaining amount display section 103 is arranged on the same surface of the main body section 3 as the power supply section 2 (here, the front surface 301). However, the configuration is not limited to this, and for example, a frame-shaped light emitting section that surrounds each of the four connection ports 21 to 24 of the power supply section 2 or the entire power supply section 2 may be provided on the front surface 301 of the main body section 3, The remaining amount display section 103 may be realized by this frame-shaped light emitting section. Further, the remaining amount display section 103 is not limited to the same surface of the main body section 3 as the power feeding section 2 (here, the front surface 301), but may be arranged, for example, on the top surface, right side surface, left side surface, etc. of the main body section 3. .

Moreover, the power supply stand 1F according to the present embodiment further includes a non-contact power receiving circuit 104. The contactless power reception circuit 104 is supplied with power from the contactless power supply circuit 204 in a contactless manner. The charging circuit 101 charges the battery 13 with the power supplied to the non-contact power receiving circuit 104. That is, in this embodiment, power is supplied to the power supply station 1F in a non-contact manner from the charging stand 200 having the non-contact power supply circuit 204 using a non-contact power supply method.

Specifically, charging stand 200 has a contactless power supply circuit 204 for contactless power supply. The contactless power supply circuit 204 includes a primary coil. In this embodiment, the primary coil is, for example, a spiral coil in which a conducting wire is spirally wound in a plan view.

As shown in FIG. 12A, the charging stand 200 includes a recess 201, a power indicator 202, a power cord 203, and a contactless power supply circuit 204. Recess 201 is formed on the top surface of charging stand 200 to match the shape of support 4 . The energization display unit 202 is realized using, for example, an LED (Light Emitting Diode) or the like, and displays the energization state of the non-contact power supply circuit 204. Power cord 203 is electrically connected to contactless power supply circuit 204 . An outlet plug is provided at the end of the power cord 203 on the opposite side from the non-contact power supply circuit 204. Therefore, for example, by connecting the outlet plug of the power cord 203 to an external power source such as an outlet installed on the wall of the living room, power is supplied from the external power source to the non-contact power supply circuit 204.

The non-contact power receiving circuit 104 is arranged on the support part 4 in this embodiment. The non-contact power receiving circuit 104 includes a secondary coil that is electromagnetically coupled (at least one of electric field coupling and magnetic field coupling) to the primary coil. In this embodiment, as an example, the secondary coil is a spiral coil in which a conducting wire is spirally wound in a plan view, similarly to the primary coil. Contactless power receiving circuit 104 is electrically connected to charging circuit 101 .

The non-contact power receiving circuit 104 includes a rectifying and smoothing circuit, which rectifies and smooths the alternating current voltage generated between both ends of the secondary coil. Then, the non-contact power receiving circuit 104 outputs the DC voltage obtained by rectification and smoothing to the charging circuit 101.

With the above configuration, the power feeding stand 1F is placed on the charging stand 200, as shown in FIG. Electric power is supplied (transmitted) to the non-contact power receiving circuit 104 from the contactless power receiving circuit 104 in a non-contact manner. The power supply stand 1F according to the present embodiment employs a magnetic resonance method (magnetic resonance method) that transmits power by making a resonant circuit including a primary coil resonate with a resonant circuit including a secondary coil. There is. However, the method of transmitting power from the charging stand 200 to the power supply station 1F is not limited to the magnetic field resonance method, and may be, for example, an electromagnetic induction method or a microwave transmission method.

By the way, the battery 13 is intended to have a large capacity by including a plurality of cells electrically connected in series or parallel, or in series and parallel. These plurality of cells are integrated by being housed in one case. The battery 13 including a plurality of cells has a so-called vertically elongated shape that is elongated in the vertical direction, as shown in FIG. 12A. The battery 13 having such a shape is housed in a so-called vertically elongated main body portion 3 that is similarly elongated in the vertical direction. That is, the battery 13 is arranged in the main body part 3 of the power supply stand 1F. Thereby, it is not necessary to provide a space for accommodating the battery 13 in the support part 4, and for example, it is possible to make the thickness of the support part 4 smaller than the thickness of the battery 13. As a result, as explained in Embodiment 2, it is possible to fix (temporarily fix) the support part 4 in a fixed position on the installation surface 91 by having a fixture such as a desk step on the support part 4. .

Here, the battery 13 is located below the center of gravity P1 of the main body portion 3. In other words, the battery 13 is arranged at a position lower than the center of gravity P1 of the main body 3, and the height H21 from the lower surface of the power feeding stand 1F to the upper end of the battery 13 is from the lower surface of the power feeding stand 1F to the center of gravity P1 of the main body 3. is lower than the height H22 to the center of gravity P1 (H21<H22). That is, the battery 13 is arranged so as to fit between the center of gravity P1 of the main body 3 and the lower end of the main body 3. Here, the power feeding section 2 is located above the center of gravity P1 of the main body section 3. In other words, the battery 13 is located below at least the power supply section 2 .

In particular, in this embodiment, the battery 13 is arranged at a position lower than the center of gravity of the entire power supply stand 1F including the main body 3 and the support part 4 (which is lower than the center of gravity P1 of the main body 3). . Specifically, the battery 13 is located at the lowest position among the plurality of components (the power feeding unit 2, the charging circuit 101, the discharging circuit 102, and the battery 13) of the main body 3. The battery 13 is arranged so that the height is less than 1/2 of the height H22 of the center of gravity P1 of the main body 3. In other words, the height H21 of the upper end of the battery 13 is less than or equal to 1/2 of the height H22 of the center of gravity P1 of the main body 3.

Since the battery 13 is relatively heavy among the multiple components of the main body 3, as described above, by positioning it as far below the main body 3 as possible, the center of gravity of the power supply stand 1F as a whole can be lowered. This makes it possible to stably install the power supply stand 1F. That is, the lower the heavy object is located, the lower the center of gravity of the power supply stand 1F as a whole can be, and the stability when installing the power supply stand 1F is improved.

However, the position of the battery 13 is not limited to the above-mentioned position, and for example, the battery 13 may be placed above the charging circuit 101 or at the same position (height) as the charging circuit 101 in the vertical direction. Further, the battery 13 may be arranged above the power supply unit 2 or at the same position (height) as the power supply unit 2 in the vertical direction.

According to the power supply stand 1F according to the present embodiment described above, power can be supplied from the power supply section 2 to the power supply target 92 without receiving power from an external power supply through the power supply cord 5. Therefore, the user 93 can more freely arrange the source of power supply to the power supply target 92, for example, in an environment such as a living room of a house, regardless of the position of an outlet or the like. That is, the power supply stand 1F can be made cordless, and the degree of freedom in arranging the source of power supply to the power supply target 92 is further increased.
