Description

Technical Field

[0001] The utility model belongs to the technical field of automobile charging piles, and in particular relates to a charging gun storage mechanism of an automobile charging pile. Background Art

[0002] New energy vehicle charging piles can be divided into two types: AC charging piles and DC charging piles. DC charging piles are power supply devices that are fixedly installed outside electric vehicles and connected to the AC power grid to provide high-power DC power for electric vehicle power batteries.

[0003] In order to realize the charging process, the charging pile functionally needs a "DC charging module" to provide DC power; a "charging pile controller" is needed to control the "power on, power off, output voltage, output current" of the charging module; a "touch screen" is needed as a human-machine interface to issue commands, and send "power on, power off, output voltage, output current" and other commands to the charging module through the controller.

[0004] Current charging piles generally have a storage and fixing mechanism for charging guns. When not charging, the charging gun is fixed to the corresponding storage and fixing mechanism to ensure that the charging gun can be stably fixed and protected. However, the general protection of the charging gun is to open a hole on the side of the charging pile and plug the charging gun into the hole for storage and protection. With such a protective structure design, a large amount of dust is easy to enter the charging socket, and its waterproof ability is poor, and the use environment is subject to certain limitations. In addition, it is difficult to stably plug and fix the charging gun, and it is easy to be pulled by external forces, causing the gun head to fall off, posing a safety hazard. Utility Model Content
