Description

Technical Field

[0001] This utility model relates to an electronic lock housing assembly, including an electronic lock comprising the electronic lock housing assembly and a charging gun comprising 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 element, a servo motor, and a position detection module. The locking element is rotatably mounted in the housing and can rotate between a locked position and an unlocked position. The servo motor, also mounted in the housing, drives the locking element to rotate between the locked and unlocked positions. When the locking element is moved to the locked position, it engages with the charging dock to lock the charging gun to it. When the electronic lock is moved to the unlocked position, it disengages from the charging dock, allowing the charging gun to be removed. The position detection module, also mounted in the housing, detects the position of the locking element. In existing technology, the electronic lock also includes multiple wires electrically connected to the servo motor and the position detection module, with the wires extending from wire holes in the housing. This not only requires separate installation of the wires but also presents challenges in sealing them to the housing, leading to difficult installation, complex sealing, and high cost.
