Description

Technical Field

[0001] The utility model relates to the technical field of safety unlocking of charging guns and charging sockets for new energy vehicles. Specifically, it relates to a novel emergency unlocking device for an electronic lock. Background Technique

[0002] In recent years, the new energy vehicle industry has developed rapidly, with an increasing number of new energy vehicles and charging stations. The charging of new energy vehicle battery packs has characteristics such as high voltage and large current. To improve the charging safety of new energy vehicles, it is stipulated in the document "GBT20234.1-2023 Connecting Devices for Conductive Charging of Electric Vehicles" that charging interfaces with alternating current charging current greater than 16A for new energy vehicles should be equipped with a locking device, namely an electronic lock. And to ensure that the electronic lock can still be unlocked and the charging gun can be unplugged when a fault occurs during the charging process of new energy vehicles, an emergency unlocking device is provided for the electronic lock of the charging interface.

[0003] Currently, in the current emergency unlocking scenarios, the traditional unlocking methods have exposed their limitations, mainly reflected in the relatively cumbersome operation process and the need for manual reset. Such methods require users to perform additional steps to restore the locked state of the electronic lock after completing the emergency unlocking action. This additional burden undoubtedly increases the operation difficulty for users and reduces the usability. More notably, the dependence on the manual reset mechanism poses a potential risk of human negligence. Users may, due to momentary negligence after successfully unlocking in an emergency, fail to reset the electronic lock in a timely manner, resulting in the electronic lock being in an unlocked state. This not only poses a safety hazard for the next charging but may also affect the normal operation and safety control logic of the entire charging system.

[0004] Regarding the problems in the related technologies, no effective solutions have been proposed yet. Summary of the Invention
