The accompanying drawing explanation
Fig. 1 is theory diagram of the present invention.
Fig. 2 is circuit theory diagrams of the present invention.
Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Fig. 1 shows the theory diagram that the present invention can give the mobile phone of other mobile phones chargings, the booster circuit that include mobile phone charging interface, charging module, the battery of mobile phone be connected with charging module, is connected with the mobile phone rechargable battery, wherein, the output of booster circuit connects the active charge switch, with the active charge switch, be connected with passive charge switch, and passive charge switch is connected to described charging module.In addition, with booster circuit, active charge switch and passive charge switch, also be connected with control circuit, and mobile phone charging interface is connected between active charge switch and passive charge switch.Control circuit is controlled the break-make of active charge switch and passive charge switch, control simultaneously booster circuit whether 5V output is arranged, active charge voltage is obtained through booster circuit by battery of mobile phone, when the user controls mobile phone and is the active charge pattern, it is logical that control circuit is controlled the active charge switch, and passive charge switch is disconnected, and make booster circuit output 5V, 5V charging voltage after boosting, through the active charge switch, is exported from mobile phone charging interface.When the user controls mobile phone and is passive charge mode, control circuit is controlled booster circuit and is exported without 5V, the active charge switch is disconnected, conducting under the effect of input charging voltage outside of passive charge switch, outer charging voltage is inputted from mobile phone charging interface, charges to local battery through passive charge switch and through charging module.
Fig. 2 shows the circuit theory diagrams that the present invention can give the mobile phone of other mobile phones chargings, and described booster circuit includes the first triode Q1, the boost module M1 be connected with the first triode and the second resistance R 2.Wherein, the emitter of the first triode Q1 connects battery of mobile phone, and base stage connects the second resistance R 2, and collector electrode connects boost module M1, and is connected to the active charge switch through boost module M1.Described active charge switch includes the second triode Q2, and described passive charge switch includes the three or three machine-operated Q3.The emitter of the second triode Q2 is connected with boost module M1, base stage is connected to control circuit by the 3rd resistance R 3, and collector electrode connects the collector electrode of passive charge switch the 3rd triode Q3, and jointly be connected to mobile phone charging interface with the collector electrode of the 3rd triode Q3.The emitter of the 3rd triode Q3 is connected to charging module M2, base stage is connected to control circuit.Control circuit includes CPU IC1 and the 4th triode Q4, wherein, the grounded emitter of the 4th triode Q4, collector electrode is connected to respectively the second resistance R 2 of booster circuit, the 3rd resistance R 3 of active charge switch and the base stage of passive charge switch the 3rd triode Q3, and the base stage of the 4th triode Q4 is connected to described CPU IC1 by the first resistance R 1, diode D1.In addition, the first resistance R 1 also forces active charge button S1 switch to connect battery of mobile phone by one, when active charge side's mobile phone is not driven machine because electric weight is not enough yet, pin this button S1 and do not put and can realize utilizing active charge side's mobile phone to charge to other mobile phone, this button S1 is Chang Kaijian.
When mobile phone is set to the active charge pattern, the pattern control pin output high level of CPU IC1, through diode D1, the first resistance R 1 makes the 4th triode Q4 saturation conduction, the collector electrode low level of the 4th triode Q4, thereby make the first triode Q1 conducting, boost module M1 input pin obtains battery of mobile phone BT1 power supply, rear output 5V boosts, due to the current collection of the 4th triode Q4 low level very, therefore the second triode Q2 conducting, the 3rd triode Q3 cut-off, 5V after boosting is through the second triode Q2, output to mobile phone charging interface, for other mobile phone charges.Otherwise, when mobile phone is set to passive charge mode, the pattern control pin output low level of CPU IC1, the base stage no current of the 4th triode Q4 and ending, collector electrode is no current also, thereby the first triode Q1 cut-off, boost module M1 loses the power supply of battery, Non voltage output, collector current due to the 4th triode Q4 is zero simultaneously, the second triode Q2 cut-off, from the charging voltage of mobile phone charging interface CN1 input, through the 4th resistance R 4, be added to the base stage of the 3rd triode Q3, make the base stage of the 3rd triode Q3 also obtain identical voltage, thereby emitter follower and the charging module M2 of outer charging voltage through being formed by the 3rd triode Q3, give battery BT1 charging.
And when active charge side's mobile phone is not driven machine because electric weight is not enough yet, even cell voltage is low to 2.5V (mobile phone can't be started shooting), the voltage of the chip output of boost module still can maintain 5V output, the S1 that now presses & hold is not put, due to oppositely not conducting of diode D1, therefore the Q4 base stage is high level, make the 4th triode Q4 conducting, the collector electrode low level of the 4th triode Q4, thereby make the first triode Q1 conducting, boost module M1 input pin obtains battery of mobile phone BT1 power supply, rear output 5V boosts, due to the current collection of the 4th triode Q4 low level very, therefore the second triode Q2 conducting, the 3rd triode Q3 cut-off, 5V after boosting is through the second triode Q2, output to mobile phone charging interface, for other mobile phone charges.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
