[0001] The present application relates to the field of cover plate locks, and in particular to an intelligent cover plate lock. Background Art

[0002] The battery compartment of an electric vehicle is used to store batteries. The battery compartment cover of a common electric vehicle is usually fixed to the body of the electric vehicle by snap-fitting. The battery compartment cover is opened when the battery needs to be replaced or the battery circuit needs to be repaired.

[0003] Since many electric vehicle battery compartment covers do not use locking devices, and most cover locks that use locking devices are locked with mechanical locks, even if the electric vehicle has a buzzer alarm device, the battery compartment cover of the electric vehicle is easy to be opened due to the lack of intelligent detection mechanism to monitor the cover lock, causing the battery to be stolen or damaged. Therefore, it is necessary to develop an intelligent cover lock to monitor the status of the cover lock. Utility Model Content
