Description

Technical Field

[0001] The utility model relates to the technical field of new energy vehicles, in particular to a clutch-type electronic lock for new energy vehicle charging equipment. Background Art

[0002] With the increasing prominence of environmental issues and the rapid development of electric vehicle technology, energy-saving and environmentally friendly electric vehicles have gradually become a development focus in the automotive industry, with a trend toward replacing fuel-powered vehicles. Electric vehicles offer numerous advantages, including safety, comfort, zero emissions, and low pollution, making them a key technology encouraged by various countries. Just as fuel-powered vehicles rely on gas stations for refueling, electric vehicles also require infrastructure such as charging stations for their energy supply. The system constructed by charging stations and their supporting facilities is a crucial component in the promotion and development of electric vehicles.

[0003] Electric vehicles require a charging gun when charging at a charging station. The structure and usage of the charging gun are similar to those of a gas pump. After removing the charging gun from the charging pile, it is inserted into the standard charging port on the electric vehicle. In order to ensure safety during charging, the charging gun needs to have a protection function, that is, to prevent the charging gun from accidentally detaching from the charging port when the charging gun is plugged in. Therefore, an electronic lock device needs to be set for the charging gun on the vehicle charging socket. When the charging gun is in the charging state, the electronic lock can lock the fastener on the charging gun, and the fastener will not be retracted even if the user accidentally touches the unlocking switch on the charging gun; at the same time, in order to cope with emergencies, the electronic lock will also be provided with a manual unlocking mechanism. The user can switch the electronic lock to the unlocked state through the manual unlocking mechanism to unlock the charging gun.
