[0032] A connecting cable body 1, the end of which is connected to a charging plug 2, and the charging plug 2 is inserted into a charging socket 3 provided in the electric vehicle;

[0033] It also includes an automatic docking structure, which is arranged between the charging plug 2 and the charging socket 3. Automatic docking between the charging plug 2 and the charging socket 3 is achieved through the automatic docking structure.

[0034] Among them, a guide groove 4 is provided on the charging plug 2, and a guide column 5 corresponding to the guide groove 4 is provided on the inner side of the charging socket 3; when the charging plug 2 is docked with the charging socket 3, the guide groove 4 and the guide column 5 can play a guiding and positioning role to ensure that the two can be docked smoothly.

[0035] Among them, the automatic docking structure includes an infrared receiver, an infrared transmitter and an electromagnet module 6;

[0036] The infrared receiver is arranged at the bottom of the guide groove 4, the infrared transmitter is arranged at the end of the guide column 5, the electromagnet module 6 is arranged on the outside of the charging plug 2, and a metal part 7 corresponding to the electromagnet module 6 is arranged on the outside of the charging socket 3;

[0037] When the charging plug 2 is inserted into the charging socket 3, the infrared signal sent by the infrared transmitter is received by the infrared receiver, and the signal is sent to the control main board inside the charging plug 2 through the infrared receiver. The control main board controls the operation of the electromagnet module 6, and under the action of the electromagnet module 6, the charging plug 2 is driven to move, so that the electromagnet module 6 contacts the metal part 7, thereby realizing automatic docking.

[0038] The charging plug 2 is provided with a power supply seat 8 inside, and a connection hole 9 is provided on the charging plug 2. An elastic conductive structure is provided in the connection hole 9, and the elastic conductive structure is connected to the charging seat 10;

[0039] The charging socket 3 is provided with a charging base 10 , and the charging base 10 is provided with a pin 11 corresponding to the connection hole 9 ; the connection end of the elastic conductive structure is in contact with the pin 11 .

[0045] When in use, the end of the charging plug is inserted into the charging socket of the electric vehicle; the guide groove on the charging plug matches the guide column inside the charging socket to ensure that the plug can be smoothly positioned during the insertion process; the setting of the guide groove and guide column avoids damage or poor contact caused by improper docking; once the plug is inserted into the charging socket, the infrared transmitter on the charging plug starts to send infrared signals; the signal is received by the infrared receiver at the bottom of the guide groove;

[0046] After receiving the signal, the infrared receiver transmits the information to the control board inside the charging plug; the control board controls the operation of the electromagnet module 6 according to the received infrared signal;

[0047] Under the action of the electromagnet module, the charging plug will make fine adjustments to ensure perfect contact with the metal part 7 of the charging socket, thereby achieving automatic docking; once docking is completed, charging begins; current is transmitted through the connecting line, forming a stable current path between the charging plug and the charging socket, providing power to the electric vehicle.

[0048] After charging is completed, the user can operate the unlocking switch through the handle on the charging plug; after pressing the unlocking switch, the control motherboard will cut off the power supply of the electromagnet module and release the connection between the charging plug and the charging socket; the user can then easily unplug the charging plug.
