Like this, at left battery (8) when using up, circuit control section (1) automatically switches to right battery (9) power supply, at this moment can right battery (9) work whenever (being before right battery electric power also discharges fully) changes left battery (8); At last when right battery (9) when using up, system's left battery (8) power supply of automaticallying switch back again, left and right sides battery can independently separately use.If the user feels to have the inconvenience that need just can allow this mobile electronic product continuous operation always by the method for continuous replacing battery and not be subjected to be brought when battery electric power was not enough in the past in the whole like this process.
Described circuit control section (1) can be realized by automatic switchover and manual switchover dual mode:
Embodiment one:
As shown in Figure 2: this circuit mainly is made up of Q201, Q202, Q203, Q204, Q205, Q206 and peripheral cell thereof.It mainly acts on is that the power supply of finishing between the battery of the left and right sides is switched, so that in use at mobile electronic product, switch to right battery (9) power supply by left battery (8) power supply, perhaps switch back left battery (8) power supply from right battery (9), in case that is to say and certain battery electric power deficiency occurs, be outputted to the supplying cell power supply output of another electric power abundance, the power interruptions that can not cause mobile electronic product just using in the handoff procedure by the supplying cell of power shortage.
Q201, Q202 are power change-over switch among the figure, we can say that also Q201 is that switch is changed in right cut, Q202 is that switch is changed in left cut, they 1., 2., 3. pin is a S end, 5., 6., 7., 8. pin is a D end, 4. pin is a control end, when 4. pin is high level, power change-over switch ends, and promptly the S end ends with the D end; When 4. pin was low level, power change-over switch was connected, and promptly the S end is logical with the D termination.Q203, Q204, Q205, Q206 are control valve, and it and its peripheral cell are formed control circuit (7) and (6), are controlling the break-make of right power change-over switch (5) and left power change-over switch (4) respectively, thereby determine supply power mode.CR221, CR222 are isolating diode.CR261, CR262 are neat sodium diode.
Do not connect when going up right battery (9) when being connected with left battery (8) on the left battery electrode interface (2), the 4. pin of Q202 is a low level, Q202 connects automatically, by 1., 2., 3. pin output voltage, this voltage divides two-way output: the CR221 of leading up to directly powers to voltage output interface (10), another road provides high level by level control circuit (7) to the 4. pin of Q201, Q201 automatic disconnection this moment, the power supply circuits of right battery electrode interface (3) interrupt, go up at right battery electrode interface (3) this moment and connect right battery (9), because of the 4. pin of Q201 is still controlled by the high level of level control circuit (7) output by Q202, so the Q201 diverter switch continues as cut-off state, the right battery (9) on the right battery electrode interface (3) is in stand-by state.When left battery electrode interface (2) is gone up the left battery (8) of connection when electric weight uses up, Q202 offers the 4. high level disappearance of pin of Q201 diverter switch by level control circuit (7), be converted to low level thus, the Q201 diverter switch is connected automatically, this moment by the right battery (9) on the right battery electrode interface (3) to Q201 1., 2., 3. pin output voltage, this voltage divides two-way output: the CR222 of leading up to directly powers to voltage output interface (10), another road provides high level by level control circuit (6) to the 4. pin of Q202, Q202 automatic cut-off this moment, the power supply circuits of left side battery electrode interface (2) interrupt, thereby avoid carrying out electric current to filling between left battery (8) and the right battery (9).
Because transport to control end 4. the voltage of pin all be to connect the voltage exported the back through handling and output by Q201 or Q202, so when changing arbitrary battery, do not influence the operating state of another battery, so the time under the state of right battery (9) power supply, left battery (8) can be taken off the battery that replaces with the electric power abundance.
Again when right battery (9) power shortage, Q201 offers the 4. high level disappearance of pin of Q202 diverter switch by level control circuit (6), be converted to low level thus, the Q202 diverter switch is connected automatically, this moment by the left battery (8) on the left battery electrode interface (2) to Q202 1., 2., 3. pin output voltage, this voltage divides two-way output too: the CR221 of leading up to directly powers to voltage output interface (10), another road provides high level to the 4. pin of Q201 once more by level control circuit (7), Q201 this moment automatic cut-off and interrupt the power supply circuits of right battery (9) once more.
In like manner, the rest may be inferred, voltage output interface (10) has all the time through the voltage output of switching, if the user feels to have the inconvenience that need just can allow this mobile electronic product continuous operation always by the method for continuous replacing battery and not be subjected to be brought when battery electric power was not enough in the past in the whole like this process.
Some mobile electronic product can have more time to give the operator because function needs the polylith battery like this, avoids the operator to change battery more frequently, is exactly three batteries circuit theory diagrams of power supply in turn among Fig. 3.
As shown in Figure 3: this circuit mainly is made up of Q301, Q302, Q303, Q304, Q305, Q306, Q307, Q308, Q309, Q310, Q311, Q312 and peripheral cell thereof.It mainly acts on is to finish three power supplies between battery to switch, so that in use at mobile electronic product, switch to right battery (9) power supply by left battery (8) power supply, perhaps switch back left battery (8) power supply from right battery (9), also or from left battery (8) switch to the 3rd battery (21), perhaps switch to left battery (8) from the 3rd battery (21) ... in case that is to say and certain battery electric power deficiency occurs, be outputted to the supplying cell power supply output of another electric power abundance, the power interruptions that can not cause mobile electronic product just using in the handoff procedure by the supplying cell of power shortage.
Q301, Q302, Q303, Q304 are power change-over switch among the figure, they 1., 2., 3. pin is a S end, 5., 6., 7., 8. pin is the D end, 4. pin is a control end, when 4. pin was high level, power change-over switch ended, promptly the S end ends with the D end; When 4. pin was low level, power change-over switch was connected, and promptly the S end is logical with the D termination.Q305, Q306, Q307, Q308, Q309, Q310, Q311, Q312 are control valve, and it and its peripheral cell are formed the break-make that control circuit is being controlled power change-over switch respectively, thereby determine supply power mode.CR321, CR322 are isolating diode.CR323, CR324 are neat sodium diode.
The same among switching principle between a left side battery (2) and the right battery (3) and top Fig. 2, here no longer describe, here be that left battery (2) and right battery (3) voltage after by circuit control section (1) control output is switched again and between the 3rd battery (21), that is to say when left battery (2) and right battery (3) when all not having electricity, circuit control section (1) just can switch output circuit to the 3rd battery (21), switches back the power supply of left battery (2) or right battery (3) after the 3rd battery (21) electric weight uses up again.The power change-over switch of the voltage after the Q303 has here become left battery (2) and right battery (3) by circuit control section (1) control output, Q304 is the power change-over switch of the 3rd battery (21), switching principle is the same with the control procedure among Fig. 2.
Left battery (8) does not all have electricity with right battery (9) when being connected with the 3rd battery (21) on the 3rd battery electrode interface (20) or when not being connected, the 4. pin of Q304 is a low level, Q304 connects automatically, by 1., 2., 3. pin output voltage, this voltage divides two-way output: the CR321 of leading up to directly powers to voltage output interface (10), another road provides high level by level control circuit to the 4. pin of Q303, Q303 automatic disconnection this moment, power supply circuits by Q303 interrupt, left battery this moment (8) all is connected with right battery (9), because of the 4. pin of Q303 is still controlled by the high level of level control circuit output by Q304, so the Q303 diverter switch continues as cut-off state, left battery (8) and right battery (9) all are in stand-by state.When the 3rd battery electrode interface (20) is gone up the 3rd battery (21) of connection when electric weight uses up, Q304 offers the 4. high level disappearance of pin of Q303 diverter switch by level control circuit, be converted to low level thus, the Q303 diverter switch is connected automatically, this moment by left battery (8) or right battery (9) to Q303 1., 2., 3. pin output voltage, this voltage divides two-way output: the CR322 of leading up to directly powers to voltage output interface (10), another road provides high level by level control circuit to the 4. pin of Q304, Q304 automatic cut-off this moment, the power supply circuits of the 3rd battery electrode interface (20) interrupt, thereby avoid carrying out electric current to filling between the 3rd battery (21) and living battery (8) or the right battery (9).
Because transport to control end 4. the voltage of pin all be to connect the voltage exported the back through handling and output by Q303 or Q304, so when changing arbitrary battery, do not influence the operating state of other battery, so the time under arbitrary battery powered state, other battery can be taken off the battery that replaces with the electric power abundance.
In like manner, again when left battery (8) and right battery (9) electric power are all not enough, Q303 offers the 4. high level disappearance of pin of Q304 diverter switch by level control circuit, be converted to low level thus, the Q304 diverter switch is connected automatically, this moment by the 3rd battery (21) on the 3rd battery electrode interface (20) to Q304 1., 2., 3. pin output voltage, this voltage divides two-way output too: the CR321 of leading up to directly powers to voltage output interface (10), another road provides high level to the 4. pin of Q303 once more by level control circuit, Q303 this moment automatic cut-off once more.
In like manner, the rest may be inferred, voltage output interface (10) has all the time through the voltage output of switching, if the user feels to have the inconvenience that need just can allow this mobile electronic product continuous operation always by the method for continuous replacing battery and not be subjected to be brought when battery electric power was not enough in the past in the whole like this process.
Above-mentioned is basic control principle, can according to circumstances select components and parts in different occasions, as in mobile phone or laptop computer, having microprocessor chip, can allow the direct output order of microprocessor chip finish by program, also can directly select to have the above electronic switch that switches of two-way or two-way.
On the bigger product of a few thing current ratio, can selective relay achieve the goal (Fig. 4).
As shown in Figure 4: between left battery electrode interface (2) and right battery electrode interface (3), relay (16) is installed, the pin of relay (16) is electrically connected with left battery electrode interface (2), 8. pin is electrically connected with right battery electrode interface (3), 3. 4. pin is electrically connected with voltage output interface (10), left side battery electrode interface (2) is connected with left battery (8), and right battery electrode interface (3) is connected with right battery (9).Its operation principle is: be provided with between the 1. pin of relay (16) and the pin left solenoid (18), 6. pin and 7. pin be provided with right solenoid (19), wherein 7. pin and pin ground connection; 2. pin and 3. pin, 4. pin and 5. pin, 8. pin and 9. pin, 10. be provided with diverter switch (17) between pin and pin, the closure of these diverter switches (17) respectively by the 1. pin on the relay (16) and 6. the voltage on the pin decide.At left battery (8) and right battery (9) all during non-existent state, its 2. pin and 3. pin, 4. pin and 5. the diverter switch between pin (17) end, 8. pin and 9. pin, 10. the diverter switch (17) between pin and pin is connected.When on the 1. pin of relay (16) voltage being arranged, left solenoid (18) work, relay (16) 2. pin and 3. the diverter switch between pin (17) connect and synchronously by the 10. diverter switch between pin and pin; When the voltage on the 1. pin of relay (16) was not enough, left solenoid (18) quit work, relay (16) again can with 2. pin and 3. the diverter switch between pin (17) by and connect synchronously 10. that the diverter switch (17) between pin and pin returns to previous status.In like manner, when on the 6. pin of relay (16) voltage being arranged, right solenoid (19) work, relay (16) is pin and the 5. diverter switch between pin (17) connection and synchronous by 8. pin and the 9. diverter switch between pin (17) 4.; When the voltage on the 6. pin of relay (16) was not enough, right solenoid (19) quit work again, relay (16) again can with 4. pin and 5. the diverter switch between pin (17) by and connect synchronously 8. pin and 9. the diverter switch between pin (17) return to previous status.Like this, after supplying cell passes through left battery electrode interface (2) and right battery electrode interface (3) input relay (16), be supplied to mobile electronic product to use by relay (16) control back by voltage output interface (10) output power, left side battery (8) and right battery (9) are that a battery is being powered all the time, and another battery is in stand-by state.When arbitrary battery electric power was not enough, relay (16) switched to the battery feed circuit of this power shortage the battery feed circuit of another battery feed circuit power supply and turned off in synchronization power shortage.
Like this, operation principle according to relay (16), when left battery (8) is powered by left battery electrode interface (2), left side battery (8) by relay 8., 9. pin divides duplex feeding, lead up to R461 to 1. pin power supply of relay, this moment is left solenoid (18) energising of pin 1., will be 10., diverter switch between the pin (17) disconnects, automatically connect 2. simultaneously, 3. the diverter switch of pin (17), another road is directly to 2. pin power supply of relay, because left solenoid this moment (18) has been worked and has been caused 2., 3. the diverter switch between the pin (17) has been connected automatically, so left battery (8) is powered to voltage output interface (10) by 3. pin.Simultaneously because 10., the diverter switch (17) between the pin disconnects, right battery (9) supply line is cut off.When left battery (8) electric weight is not enough, arrive the 1. loss of voltage of pin of relay by R461, this moment, 1. the left solenoid (18) of pin quit work, 10., the diverter switch (17) between the pin returns to on-state return to previous status so again:, 2., the 3. diverter switch between the pin (17) automatic disconnection again, left battery (8) power supply circuits are cut off.If right battery this moment (9) exists, right battery (9) by behind the right battery electrode interface (3) through 10., the pin divides duplex feeding, 6. the R462 of leading up to powers to the relay pin, this moment is right solenoid (19) energising of pin 6., will be 8., 9. the diverter switch between the pin (17) disconnects, automatically connect 4. simultaneously, 5. the diverter switch between the pin (17), another road is directly to 5. pin power supply of relay, because right solenoid this moment (19) has been worked and has been caused 4., 5. the diverter switch between the pin (17) has been connected automatically, so right battery (9) is powered to voltage output interface (10) by 4. pin.While 8., 9. the diverter switch between the pin (17) disconnects, and left battery (8) supply line is cut off, thereby guarantees not carry out filling between right battery (9) and the left battery (8).With should right battery (9) when power shortage occurring again, equally can switch back left battery (8) and power.
In addition, this battery powdered device can be set directly on the mobile electronic product, and also can being provided with independently, battery powdered device cooperates mobile electronic product to use.
