Fig. 1, 2 shows, the utility model discloses fill electric pile body 1 based on electric automobile, electric automobile fills electric pile body 1 other methods of use and current electric automobile and fills electric pile completely unanimous, the person that charges sweeps back such as sign indicating number through the cell-phone, fill main control board output power to the charging source board in the electric pile body 1, charging source board output charging source to filling the supporting rifle 102 that charges of electric pile, follow-up person that charges will fill electric pile just can charge for vehicle battery after rifle 102 inserts the battery charging socket of car in, take out the rifle that charges after having filled the electricity, the main control board detects the back, control charging source board loses the electricity, third party application software charges the whole processes of charging of accomplishing to the charging amount of person who charges. In this novel, after 220V alternating current power supply got into 1 and 2 feet of constant voltage power supply U1, constant voltage power supply U1 can export stable direct current 12V power under its internal circuit effect and get into trigger circuit and control circuit's power input end, then trigger circuit and control circuit are in the working condition that obtains electricity. In practical situations, a person who has to charge the vehicle storage battery at every time scans codes through a mobile phone, 3 and 4 pins of the charging power panel output power to the charging gun, and the person who charges presses the power switch S1 to loosen the charging gun (the front end of the charging pile body can be pasted with text information prompting the operation process of the person who charges), so that the positive pole of the 12V power supply can enter the 3 pins of the dual-D trigger U2, and in practical situations, when the 3 pins of the dual-D trigger U2 do not input high level signals, the bistable circuit inside the dual-D trigger is in a stable state with no output at the 1 pin, so the relay K1 can not be powered and attracted. When a charger presses the power switch S1 before charging, a high level enters the pin 3 of the double-D trigger U2, then a bistable circuit in the double-D trigger U2 overturns once, the pin 1 outputs the high level, the high level is subjected to voltage reduction and current limitation through the resistor R1 and enters the base electrode of the NPN triode Q1, then the NPN triode Q1 conducts the collector, outputs the low level and enters the negative power input end of the relay K1, the relay K1 is electrified, the control power input end and the normally open contact end of the relay are closed, and the control power input end and the normally closed contact end of the relay are opened. Because the 3 feet of the time control switch U3 are connected with the normally open contact end of the relay K1, the time control switch U3 can be input with a trigger signal and then triggered, the time control switch U3 outputs 12 seconds of power to the power input end of the relay K2 under the action of the internal circuit of the time control switch U3 and the time of outputting power by 9 feet set by technicians, the 9 feet of the time control switch U3 can output 12 seconds of power to enter the power input end of the relay K2, the relay K2 is electrified to attract the two control power input ends and the two normally open contact ends of the relay, the power output shaft of the motor speed reducing mechanism M is electrified to rotate clockwise to gradually unreel the charging wire 101 stored at the outer end of the winding drum, a charger pulls the charging gun by hand, the charging wire moves forward to be close to a charging socket of the electric vehicle, therefore, the charging wire can be effectively unreeled during the walking of the charger in 12 seconds, the motor speed reducing mechanism M does not work any more when the charging wire is lost, the length of the charging wire is longer, the charger can charge the vehicle battery by inserting the charging gun 102 of the charging pile into a battery charging socket of the automobile.

As shown in fig. 1 and 2, after the charger finishes charging and takes off the charging gun, the charger presses the power switch S1 again by hand, so that the positive electrode of the 12V power supply enters the pin 3 of the dual D flip-flop U2 again, the bistable circuit in the dual D flip-flop U2 (the pin 1 of which cyclically outputs a high level and stops outputting a high level after cyclically inputting a high level signal in the pin 3) again flips the pin 1 thereof to stop outputting a high level, the NPN triode Q1 is turned off, and the relay K1 loses power and no longer attracts the control power supply input end and the normally open contact end to open, and the control power supply input end and the normally closed contact end to close. Because the 3 feet of the time control switch U4 are connected with the normally closed contact end of the relay K1, the time control switch U4 can be input with a trigger signal and then triggered at the moment, the time control switch U4 outputs a power supply for 12 seconds under the action of the internal circuit of the time control switch U4 and the time of the 9 feet output power supply set by a technician, the 9 feet of the time control switch U4 can output a power supply for 12 seconds to enter the power supply input end of the relay K3, the relay K3 is electrified to attract the two control power supply input ends and the two normally open contact ends of the relay K3556 to be closed respectively, the power output shaft of the motor speed reducing mechanism M which is electrified in negative and positive polarity rotates anticlockwise and gradually winds up a charging wire through the winding drum, after 12 seconds, the motor speed reducing mechanism M loses electricity and does not work, and the charging wire is completely wound outside the winding drum to complete winding work at the moment.

Fig. 1, 2 shows, in this novel, when motor reduction gears 51's power output shaft drives connecting axle 55 pivoted, connecting axle 55 drives the winding reel 54 and rotates, because the inner circle of only two bearings 52 rotates this moment, the outer lane does not rotate, two wires of charging wire head end can be respectively through the inner circle of two bearings 52, the copper ball of two bearings, the outer lane of two bearings, and fill charging source board power output both ends electric intercommunication respectively in the electric pile body 1, guaranteed like this that to fill the power of charging source board power output both ends output in the electric pile body 1 can be effectively through charging wire and terminal rifle 102 output that charges to can guarantee that charging wire 101 effectively rotates with motor reduction gears under the prerequisite, can also normally export power. Through above-mentioned all circuit and mechanism combined action, when the person that charges needs the pulling charging wire to expand in the application, when having filled the electricity back and need the charging wire to accomodate automatically, only need simply press switch after, motor reduction gears can drive the winding reel clockwise or anticlockwise rotation automatically, and then realizes emitting the charging wire or accomodate the control purpose of charging wire. This novel person that charges need not stimulate the charging wire hard before charging, does not need the manual charging wire of accomodating after having filled the electricity, can accomplish automatically and receive and release the line, has brought the facility for the person that charges, and receive line speed even, has effectively prevented the rifle that charges and has damaged because of the collision.
