Charging plug 1 is transported at guide stop block 24；Guide stop block guides charging plug to leave outer rotary table from export notch.
If not pressing interior ejector button in car owner five minutes, it is considered as and does not need to charge, be directly entered step 10.
Step 3: single-chip microcontroller control limited block 20 is powered and generates electromagnetic field, charging plug 1 is attracted to the outer of limited block 20
In side edge, and one of vehicle end charging interface of charging plug 1 is towards outside.At this point, single-chip microcontroller control outer rotary table 22 and
In turntable 23 power off loss of excitation.
Step 4: sending compression signal to single-chip microcontroller after the pressure sensor compression being embedded on limited block.Single-chip microcontroller control
Cylinder 19 is shunk, and limited block 20 is separated with rotating disk mechanism 4.
Step 5: steering engine 18 rotates forward, so that the stake end of the vehicle end charging interface face charging socket on charging plug 1 outwardly
Charging interface.
Step 6: cylinder 19 is released, the stake end charging of vehicle end charging interface and charging socket on charging plug 1 outwardly
Mouth docking.Automobile starts to charge.
Step 7: cylinder 19 is shunk after automobile charging complete, so that charging plug 1 is separated with charging socket, steering engine 18 is anti-
Turn to reset.Mobile phone app prompt car owner pays the fees and recycles charging plug.
Step 8: single-chip microcontroller control limited block power-off loss of excitation is pulled back 6 turns of motor after user presses interior recycling button
Dynamic, charge cable is around upper roll shaft 10.Charging plug 1 returns in the ejection channel of automobile, and compress the spring 15 in ejector 3 to
Initial position.
Step 9: the loading sliding block 13 in 16 locking ejector 2 of lockable mechanism.
Step 10: charging terminates.
