Description

The portable power source that a kind of input/output interface is shared
Technical field
The utility model belongs to technical field of electronic equipment, relates to the shared portable power source of a kind of input/output interface.
Background technology
Existing portable power source all is two interfaces, and it is the charging of accumulate pond that interface is used for, and the another one interface then is used for being connected with equipment to be charged and charges.The corresponding in actual applications deficiencies such as structure is not compact, use inconvenience that also have of this double nip formula portable power source.
The utility model content
The purpose of this utility model is to overcome the deficiency that prior art exists, and a kind of compact conformation, the cost shared portable power source of input/output interface low, easy to use are provided.
The technical solution that adopts is so for achieving the above object: the shared portable power source of the input/output interface that is provided comprises the I/O interface, charging circuit, booster circuit, the accumulate pond, two PNP triodes, two NPN triodes and two devices such as electric capacity, it is characterized in that: terminals of I/O interface are connected to the input of charging circuit and the output of booster circuit simultaneously, the output of charging circuit is connected to the e of first PNP triode simultaneously, the b utmost point (emitter, base stage) and the c utmost point (collector electrode) of first NPN triode, the c utmost point of first PNP triode is connected to just (+) utmost point in accumulate pond simultaneously, the e of second PNP triode, the c utmost point of the b utmost point and second NPN triode, negative (-) utmost point in accumulate pond is connected to the reference ground of booster circuit simultaneously, the e utmost point of second NPN triode, the b utmost point of first NPN triode and the reference of charging circuit ground, the c utmost point of second PNP triode connects with the input of booster circuit, the e utmost point of first NPN triode and the b utmost point of second NPN triode are attached to another terminals of I/O interface respectively, and two electric capacity are connected in the e of two PNP triodes respectively, between the c utmost point.
In the real work, when needs charge for portable power source accumulate pond, external power supply circuits are plugged on the I/O interface, behind the circuit start, supply current successively through charging circuit, first electric capacity to accumulate pond positive pole, be back to external power supply circuits by accumulate pond negative pole through first NPN triode again, this moment first PNP triode and first equal conducting of NPN triode, second PNP triode ends, and promptly gives the charging of accumulate pond by first PNP triode after stablizing always; When the needs portable power source is that the external world treats power supply unit when power supply, disconnect external power supply circuits, to treat that power supply unit is plugged on the I/O interface, after starting power supply, then supply current by accumulate pond positive pole successively through second electric capacity, booster circuit, treat that power supply unit and second PNP triode are back to accumulate pond negative pole, this moment second PNP triode and second equal conducting of NPN triode, first NPN triode ends, and promptly treats power supply unit by second PNP triode after stablizing always and powers.
Compared with prior art, design novelty of the present utility model, simple and compact for structure, cost is low, easy to use, realized the shared purpose of portable power source input and output mouth.
Description of drawings
Accompanying drawing is the structural representation of a specific embodiment of the utility model.
Embodiment
Below with reference to accompanying drawing the utility model content is described further.
Referring to accompanying drawing, the shared portable power source of input/output interface described in the utility model is by I/O interface 1, charging circuit 2, booster circuit 3, accumulate pond 4, two PNP triode Q 1, Q 2, two NPN triode Q 3, Q 4, capacitor C 1, C 2And resistance R 1, R 2, R 3, R 4Form Deng device.Terminals of I/O interface are connected to the input of charging circuit 2 and the output of booster circuit 3 simultaneously, and the output of charging circuit 2 is connected to PNP triode Q simultaneously 1E, the b utmost point and NPN triode Q 3The c utmost point, PNP triode Q 1The c utmost point be connected to the positive pole and the PNP triode Q in accumulate pond 4 simultaneously 2E, the b utmost point and NPN triode Q 4The c utmost point, the negative pole in accumulate pond 4 is connected to reference ground, the NPN triode Q of booster circuit 3 simultaneously 4The e utmost point, NPN triode Q 3The b utmost point and the reference of charging circuit 2 ground, PNP triode Q 2The c utmost point connect NPN triode Q with the input of booster circuit 3 3The e utmost point and second NPN triode Q 4The b utmost point be attached to another terminals of I/O interface 1, capacitor C respectively 1Be connected in PNP triode Q 1E, the c utmost point between, capacitor C 2Be connected in PNP triode Q 2E, the c utmost point between.Alphabetical label RL is for treating power supply unit among the figure, and power is external power supply circuits, and the booster circuit 3 in the equipment can adopt the TL1616 device, and charging circuit 2 is the normal charge circuit.The utility model makes by said structure design that the input and output mouth of portable power source is shared to be the I/O interface.
When charging for portable power source accumulate pond 4, external power supply circuits power is plugged on the I/O interface 1, behind the circuit start, charge circuit is: external power supply circuits positive pole → charging circuit → capacitor C 1→ accumulate pond positive pole → accumulate pond negative pole → NPN triode Q 3Base stage → NPN triode Q 3Emitter → external power supply circuits negative pole.This moment NPN triode Q 3Conducting, PNP triode Q 2End PNP triode Q 1PNP triode Q is passed through in conducting always after stablizing 1Give the accumulate pond 4 chargings.
When disconnecting external power supply circuits power, when powering for equipment RL to be charged, promptly be to be equivalent to connect treat power supply unit RL (will treat that power supply unit RL is plugged on the I/O interface 1), behind the start-up circuit, current circuit is: accumulate pond positive pole → capacitor C 2→ booster circuit 3 → equipment RL to be charged → NPN triode Q 4Base stage → NPN triode Q 4Emitter → accumulate pond negative pole.This moment NPN triode Q 2Conducting, NPN triode Q 3End PNP triode Q 2Conducting is treated charging device RL by triode Q2 after stablizing always and is charged.
