Description

Technical Field

[0001] This utility model relates to an electronic lock for locking a charging gun to a charging dock. Furthermore, this utility model also relates to a charging gun incorporating the electronic lock. Background Technology

[0002] In existing technology, when a charging gun is plugged into a charging dock, an electronic lock is installed on the charging gun to lock it to the dock and prevent accidental separation. Typically, this electronic lock includes a housing, a locking member, and a servo motor. The locking member is rotatably mounted in the housing and can rotate between a locked position and an unlocked position. The servo motor is mounted in the housing and drives the locking member to rotate between the locked and unlocked positions. When the locking member of the electronic lock is moved to the locked position, it engages with the charging dock to lock the charging gun to the dock. When the electronic lock is moved to the unlocked position, the locking member disengages from the charging dock, allowing the charging gun to be removed from the dock. In existing technology, a slot is formed in the housing, and the locking portion of the locking member protrudes from this slot for engagement with the charging dock. Therefore, the existing housing's inner cavity is an open cavity that communicates with the outside. Moisture can enter the inner cavity of the housing through slots, which requires the servo motor itself to have waterproof function. For example, the servo motor needs to have a waterproof rating of IPX or higher. However, servo motors with waterproof function are expensive, which increases the cost of the electronic lock.
