Abstract
Description
Technical Field
[0001] This utility model belongs to the field of new energy electric vehicles, and specifically relates to an AC / DC charging socket. Background Technology
[0002] An electronic lock for a charging socket is an electronic device used to lock and unlock charging sockets, primarily to prevent operators from accidentally disconnecting the charging connector (commonly known as the charging gun), thereby avoiding the risk of electric shock. In standard AC / DC charging sockets, the AC charging port and DC charging port are independent ports, requiring separate electronic locks for control of the AC and DC charging / discharging guns. This necessitates the use of dedicated locks for different charging scenarios, increasing equipment complexity and cost. Furthermore, early electronic locks generally suffered from bulkiness, insufficient thrust, and failure in emergency unlocking, making them unsuitable for the integration requirements of compact charging stations.

The first locking pin 12 extends horizontally from above the first locking groove 7 and abuts against the locking rod 15 of the AC charging gun 6, preventing the locking rod 15 from being pressed to unlock, thereby achieving a locking function.
[0024] The second locking pin 13 is vertically inserted into the locking groove 16 on the side of the DC charging gun 8, so that the DC charging gun 8 cannot be pulled out, thereby playing a locking role.
[0025] Preferably, the drive mechanism 14 includes a motor 17, a primary gear 18, a secondary double gear 19, a tertiary double gear 20, a quaternary gear 21, a first transmission shaft gear 22, and a second transmission shaft gear 23.

Both ends of the tertiary double gear 20 mesh with the first transmission shaft gear 22 and the quaternary gear 21, respectively. The other end of the quaternary gear 21 meshes with the second transmission shaft gear 23. The first transmission shaft gear 22 meshes with the first locking rack 24 at the rear end of the first locking groove 7, and the second transmission shaft gear 23 meshes with the second locking rack 25 at the rear end of the second locking pin 13. This mechanism enables synchronous movement of the first locking pin 12 and the second locking pin 13, and has the advantages of high thrust and small size.
[0026] Preferably, the back of the flange panel 1 is provided with a mounting groove 26 for the front end of the lock housing 11 to be inserted, and the mounting groove 26 is provided with a first locking hole 27 for the first locking pin 12 to extend out.
