Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model,
Fig. 2 is the wire connecting block figure in the utility model use procedure.
Drawing illustrates: 1, housing, 2, USB joint, 3, USB interface, 4, control chip.
Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in further detail.
A kind of mobile phone over-charge protective device, comprise housing 1, be arranged at the USB joint 2 that housing 1 two ends are connected with charger for mobile phone respectively and the USB interface 3 be connected with mobile phone charging data line, the inside of housing 1 is provided with control chip 4, this control chip 4 comprises control unit and switch element, wherein the input of control unit is connected by the output of circuit with the chip for cell phone of mobile phone terminal, the output of control unit is connected with the input of switch element by circuit, described switch element comprises diode AND gate circuit, the output of this diode AND gate circuit is connected with the battery of mobile phone terminal by circuit, the input of diode AND gate circuit is connected with the charger for mobile phone of feeder ear by circuit.
Control principle of the present utility model is:
1, battery of mobile phone overcharges the solution of problem
Battery of mobile phone is when unsaturation state; control chip is in channel status; electric current charges by over-charge protective device; after being full of electricity; electric current completely instruction is sent by the mobile phone house keeper on chip for cell phone; control unit in control chip receives instruction and switch element is passed in corresponding instruction, and realize becoming off state from channel status by switch element, now battery of mobile phone will not recharge.
2, charging limit in mobile phone limit uses the solution of charging problems
When mobile phone charges on use limit, limit, most cases charged electrical flow is greater than practical current sinking amount, when battery is in saturation condition, electric current completely instruction is sent by the mobile phone house keeper on chip for cell phone, control unit in control chip receives instruction and switch element is passed in corresponding instruction, realize being converted to off state by channel status by switch element, after use consumes certain electricity, battery is no longer in saturation condition, mobile phone house keeper now in chip for cell phone sends instruction again, the control unit of control chip receives instruction and switch element is passed in corresponding instruction, realize being converted to channel status by off state by switch element and continue charging.
The solution of 3, energy waste problem
After battery of mobile phone is in saturation condition, over-charge protective device realizes auto-breaking by control chip, avoids unnecessary energy waste problem.
4, the solution of battery loss problem
After battery of mobile phone is in saturation condition, continues charging, battery can be made to be in hypersaturated state, can make shorter battery life like this, use over-charge protective device can prevent the damage to battery of mobile phone.
Above embodiment is only and technological thought of the present utility model is described; protection range of the present utility model can not be limited with this; every technological thought according to the utility model proposes, any change that technical scheme basis is done, all falls within the utility model protection range.
