17 input, the output end of steady-state circuit 17 connects the base stage of triode 8 by diode.
The application process explanation of the present invention：
When the electronic equipments such as mobile phone, portable power source are placed on charging panel 12, due to left elasticity in charging inlet circuit
Centre distance between electrode 5 and right elastic electrode 6 is with the distance between charging panel 12 Top electrode A, B, C equal, its charging
Left elastic electrode 5 and right elastic electrode 6 in mouth circuit is just accurate with the electrode A on charging panel 12, any two in B, C
Contact, detection resistance 3 is connected by left elastic electrode 5, right elastic electrode 6 with detection circuit 14, three poles in detection circuit 14
Pipe will turn on, colelctor electrode output positive voltage turn on photoelectrical coupler 7, driving triode 8 turn on, triode 8 make power supply after
The control coil of electrical equipment 11 is powered, and power supply relay 11 is closed, and supply voltage+V is added on voltage-stablizer 9 by resistance 10, voltage stabilizing
Device 9 exports more stable voltage and is transported to by switching relay 13 on charging panel 12, and the electrode A, B, C on charging panel 12 will
Charging current is transported in the interface circuit of charging equipment, begins to charging.
After charging starts, CP of the pulse input that pulse control circuit 18 produces impulse generator 19 to counter 15
During end, the control switching relay 13 of counter 15 is switched on and off, and makes to be output to charging panel 12 electrode A, the voltage on B, C just
Negative polarity changes with the change of output end QA, the QB level of counter 15；Charging inlet negative pole 1 and charging inlet positive pole 2 with
The charging both positive and negative polarity correspondence of the electronic equipments such as mobile phone, portable power source, charging diode 4 correctly selects charging polarity, will positive electricity
Pressure is added on charging inlet positive pole 2.
When the charging equipments such as mobile phone, portable power source are started to charge up, amplifying circuit 16 detects charging electricity by resistance 10
After stream, the voltage of the output end of amplifying circuit 16 is changed into high level from low level, and pulse control circuit 18 stops to counter 15
CP ends input pulse, output end QA, the QB level of counter 15 will keep existing state, and a, b, c of switching relay 13 are defeated
Go out terminal voltage positive-negative polarity no longer to change, while the electrode A, B, C voltage polarity on charging panel 12 also no longer change, keep current
Charged state, be allowed to continual and charged；In whole charging process, the charging current that voltage-stabiliser tube 9 is exported is logical
Overcharge the electrode A on electroplax 12, B, C and be sent to what left elastic electrode 5, right elastic electrode 6 in interface circuit got on, charging circuit
Resistance is small, and charging current is big, and the charging interval is short, overcomes conventional wireless charger in charging in electromagnetic propagation and reception process
Charging current that energy loss is brought greatly is small, charging interval length shortcoming.
The input of steady-state circuit 17, steady-state circuit 17 are connected to after the inverted device 20 of the output voltage of amplifying circuit 16 is anti-phase
Q2 output termination triode 8 base stage, when charging stream be less than 50mA when, amplifying circuit 16 output low level, steady-state circuit 17
Q2 output ends high level is changed into from low level, force triode 8 to end, power supply relay 11 disconnects, charging stop, now only
There are detection circuit 14 and power supply relay 11 to be in holding state, other all circuits will all be stopped, and reduce whole electricity
The power consumption on road.
The present invention only needs to the interface electricity that the electronic equipments such as mobile phone, portable power source insert a very little in its charging inlet
Road module is with regard to that can be charged, without being equipped with other annexes, and circuit is simple, easy for installation.It not only overcomes wireless charger
The shortcoming of charging interval length, while also overcoming wireless charger needs to install transmitting and receiving coil, cost is high, volume is big,
Complexity is installed and there is electromagnetic radiation.
