[0033] The working principle of the embodiment of the present invention is as follows: the electric car is driven to the front of the base 1, and the guide ring 21 is removed from the placement frame and mounted on the charging interface 8 of the electric car. After the driver performs the charging confirmation operation on the operation screen 201, the receiver 7 positions the transmitter 9, and the movable seat 2 is horizontally slid by the feedback motor 4, and the height of the charging gun 5 is adjusted by the second servo motor 13. Finally, the charging gun 5 is moved forward by the first servo motor 10. The guide ring 21 can guide the position of the charging head 6 so that the charging head 6 can be accurately docked with the charging interface 8, and the distance between the receiver 7 and the transmitter 9 can be used to determine the depth of the charging head 6 inserted into the charging interface 8. When the distance between the receiver 7 and the transmitter 9 reaches a preset value, the first servo motor 10 stops working. After charging is completed, the charging head 6 automatically resets, and then the driver removes the guide ring 21 from the charging interface 8 and puts it back into the placement frame.
