In the correlation technique, can put into the storehouse of charging 100 after the bluetooth headset does not have the electricity and charge because the storehouse of charging 100 has the characteristics of conveniently carrying and accomodating. Further, the charging bin 100 has a wireless charging function, and the wireless charging can be more convenient for an operator to use. Specifically, wireless charging function is in the charging process to the storehouse 100 that charges, and the electric energy of the source of charging still has partly electric energy loss to turn into heat energy except changing to the storehouse 100 that charges inside, and wherein, this partly heat energy not only can bring different degree interference and damage to the important components and parts in storehouse 100 that charge, can influence the wireless efficiency of charging in storehouse 100 moreover. Thus, the present application proposes a charging magazine 100.

Referring to fig. 1 and 2, in some embodiments, the charging bin 100 includes: a housing 200, a charging assembly 300, and a heat conductive member 400, the housing 200 defining a storage chamber 210; the charging assembly 300 includes a charging ring 310, and the charging assembly 300 is disposed in the storage cavity 210; the heat conductive member 400 is thermally connected to the charging assembly 300. For example, the heat conduction member 400 is connected to the charging assembly 300, so that when the charging bin 100 adopts a wireless charging function, the heat conduction member 400 can absorb heat for the charging assembly 300, so as to reduce interference and damage to important components.

In order to make the heat conducting member 400 absorb heat well, the heat conducting member 400 may be disposed on one side of the charging ring 400 of the charging assembly 300, and the other side of the charging ring 400 is used for corresponding connection with a charging source to perform wireless charging.

Further, in some embodiments, the charging assembly 300 further includes a magnetic shielding sheet 320, one side of the charging ring 310 is disposed toward the inner wall of the storage cavity, the other side of the charging ring 310 is connected to one side of the magnetic shielding sheet 320, and the other side of the magnetic shielding sheet 320 is thermally connected to the heat conductive member 400. The wireless charging function of the charging chamber 100 is mainly to charge the charging chamber 100 by the contact between the charging ring 310 and the magnetic shield 320 and the external charging source. Since the wireless charging function can adopt the electromagnetic induction technology, the magnetism isolating sheet 320 plays a role in isolating the magnetic field. Specifically, when the charging ring 310 contacts with an external charging source, the electromagnetic induction converts the electric energy of the charging source into the charging chamber 100, and a certain amount of heat is generated at the same time, so that the heat conducting member 400 is connected with the magnetism isolating sheet 320 to absorb heat, thereby reducing the interference and damage to important components.

Further, referring to fig. 3 and 4, in some embodiments, the thermal conductive member 400 includes a substrate 410 and a filler 420, the substrate 410 is provided with a through hole 411 and/or a groove 412, and the filler 420 is disposed in the through hole 411 and/or the groove 412. For example, the volume of the charging bin 100 is very small, and therefore it is critical to make reasonable use of the space of the storage chamber 210 inside the charging bin 100. Further, it is required that the heat conduction member 400 not only can absorb heat to the charging assembly 300, having a good heat absorption capability, but also that the heat conduction member 400 cannot occupy too much space, and meanwhile, the heat conduction member 400 is also required to facilitate a worker to assemble the heat conduction member 400 to the charging assembly 300 when assembling the charging bin 100. Accordingly, the heat conductive member 400 may include a substrate 410 and a filler 420, the substrate 410 being provided with a through hole 411 and/or a groove 412, and the filler 420 being provided in the through hole 411 and/or the groove 412. Wherein, obturator 420 and base plate 410 can select for use the material that has better heat-absorbing capacity to make, so, can be to the subassembly 300 that charges when wireless charging, absorb heat to can be directly with base plate 410 assembly connection subassembly 300 that charges.

Further, referring to fig. 5, in some embodiments, a plurality of through holes 411 and/or slots 412 are disposed, and the plurality of through holes 411 and/or slots 412 are disposed along the length direction of the substrate 410. For example, in order to make the heat-absorbing effect of the heat-conducting member 400 good, the filling body 420 may be made of a better heat-conducting material, such as silicon cement. Specifically, when the filling body 420 is disposed in the through hole 411 or the groove 412, it is conceivable that the more the filling body 420, the better the heat absorbing effect. Therefore, the plurality of through holes 411 or grooves 412 of the substrate 410 are disposed along the length direction of the substrate 410, and the heat absorbing effect of the heat conductive member 400 can be improved.

Note that a plurality of through holes 411 or a plurality of grooves 412 may be provided in the substrate 410, and the substrate 410 may be provided in combination with the plurality of through holes 411 and the grooves 412.

Further, referring to fig. 3, in some embodiments, the substrate 410 is made of EVA (ethylene vinyl acetate copolymer), and the filler 420 is made of silicon cement. For example, silica gel paste is an excellent heat conductive medium, has excellent thixotropy, and can be kneaded into any shape. Therefore, when the filling body 420 is made of silicon cement, the substrate 410 made of EVA is provided with a plurality of through holes 411 or grooves 412, and the silicon cement is disposed in the plurality of through holes 411 or grooves 412, so that the heat conducting member 400 has a good heat conducting effect, and can radiate and absorb heat for the charging assembly 300, thereby reducing interference and damage to important components.

It should be noted that, since the silica gel is easily deformed, if the silica gel is directly connected to the magnetism isolating sheet 320, the charging assembly 300 absorbs heat. The silica gel mud can not be stably connected to the magnetism isolating sheet 320 to absorb heat. Therefore, the charging assembly 300 can be stably heat-absorbed by combining the EVA substrate 410 and the silicon cement.

Further, referring to fig. 4, in some embodiments, the heat conducting member 400 further includes a first adhesive plate 430, one side of the first adhesive plate 430 is adhered to the magnetic shielding sheet 320, and the other side is adhered to the substrate 410. For example, the heat conductive member 400 has a good heat absorbing capability, and therefore, a worker needs to tightly attach the heat conductive member 400 to the magnetism isolating sheet 320 so as to absorb heat to the magnetism isolating sheet 320 at any time. Further, the first adhesive sheet 430 of the heat conductive member 400 has one side adhered to the magnetic separator 320 and the other side connected to the substrate 410, and it is conceivable that the substrate 410, the filler 420 and the first adhesive sheet 430 can be firmly connected to the magnetic separator 320 to absorb heat from the charging assembly 300. The first bonding plate 430 may be a double-sided adhesive tape, and the magnetic isolation sheet 320 and the substrate 410 may be conveniently bonded by the double-sided adhesive tape.

Further, referring to fig. 2, in some embodiments, the charging bin 100 further includes a battery 500 and an inner housing 600, the charging assembly 300 is electrically connected to the battery 500, the inner housing 600 is disposed in the storage cavity 210, the inner housing 600 is disposed with an installation cavity, the battery 500 is disposed in the installation cavity, one side of the heat conducting member 400 is connected to one side of the inner housing 600, and the other side is connected to the magnetic shielding sheet 320. For example, it is conceivable that the charging chamber 100 has both wired charging and wireless charging functions, and therefore, the battery 500 may generate heat during charging regardless of wired or wireless charging. Since the battery 500 generates heat, which affects the normal use and life of other important components, the inner case 600 can separate the battery 500 from other components. Further, when the charging chamber 100 is wirelessly charged, the heat conductive member 400 can absorb heat to the charging assembly 300, and the heat conductive member 400 is spaced from the battery 500 by a certain distance and is only connected to the inner case 600, so that the battery 500 is not affected. When the charging chamber 100 is charged in a wired manner, the wireless charging function is not used, and therefore, some heat emitted from the battery 500 is absorbed by the heat-conducting member 400. Thus, the heat-conducting member 400 has many application scenarios.

Further, referring to fig. 4, in some embodiments, the heat conduction member 400 further includes a second adhesive plate 440, and the second adhesive plate 440 is used for adhering the heat conduction member 400 to one side of the inner housing 600. For example, in order to couple the heat conduction member 400 to the inner case 600, the second adhesive sheet 440 may be double-sided adhesive, so that the heat conduction member 400 can be preferably adhered to the inner case 600.

Further, referring to fig. 2, in some embodiments, the heat conducting member 400 includes a silicone pad connected to the magnetic shielding sheet 320. For example, the silicone pad has a good thermal conductivity, and therefore, the thermal conductive member 400 may be a silicone pad, and the silicone pad is connected to the magnetic shielding sheet 320, and can absorb heat to the charging assembly 300.

Further, referring to fig. 2, in some embodiments, the charging assembly 300 further includes a circuit board 330, the circuit board 330 is disposed on the bottom wall of the storage cavity 210, and the charging ring 310, the magnetic shielding sheet 320 and the heat conducting member 400 are disposed on the side wall of the storage cavity 210. For example, the circuit board 330 may not be easily damaged by external factors, such as high temperature. Therefore, the circuit board 330 is disposed on the bottom wall of the storage cavity 210, and the charging ring 310, the magnetic shielding sheet 320 and the heat conducting member 400 are disposed on the side wall of the storage cavity 210, specifically, the circuit board 330, the charging ring 310, the magnetic shielding sheet 320 and the heat conducting member 400 are separated, and heat generated by the charging ring 310 during wireless charging does not affect the circuit board 330, thereby damaging the circuit board 330.

Although the circuit board 330 is disposed on the bottom wall of the storage cavity 210, and the charging ring 310, the magnetic shielding sheet 320 and the heat conducting member 400 are disposed on the side wall of the storage cavity 210, the disclosure is not limited thereto, and the circuit board 330 may be disposed on the side wall of the storage cavity 210, and the charging ring 310, the magnetic shielding sheet 320 and the heat conducting member 400 are disposed on the bottom wall of the storage cavity 210, and the description thereof is omitted.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention. Furthermore, the embodiments of the present invention and the features of the embodiments may be combined with each other without conflict.
