Standby self-charging device for face recognition intelligent door lock

Abstract

The invention relates to the technical field of face recognition intelligent door locks, and discloses a standby self-charging device for a face recognition intelligent door lock. The device comprisesa lock body. A locking body is installed on the left side in the lock body. A first gear is installed on the right side of the locking body. A second gear is installed on the right side of the firstgear. A disc is installed on the right side of the second gear. Sliding rods are connected to the upper end and the lower end of the disc. Magnets are connected to the tops of the sliding rods. Limiting rings are installed on the upper side and the lower side of the disc correspondingly. A coil barrel is installed above the limiting ring on the upper side. A storage battery is installed above thecoil barrel. According to the standby self-charging device for the face recognition intelligent door lock, when a door is opened or closed each time, mechanical energy of rotating a door handle is converted into electric energy to be stored in the storage battery, when a power module is power off, the storage battery supplies power, thus a face recognition module is used normally, the problem thatwhen a mechanical key is forgotten, the difficulty of coming in and out is caused is solved, energy sources are saved, and when the storage battery supplies the power, a warning lamp flickers to remind people to replace dry cells.

Description

technical field [0001] The invention relates to the technical field of face recognition smart door locks, in particular to a backup self-charging device for face recognition smart door locks. Background technique [0002] Face recognition technology refers to the use of computer technology for analysis and comparison to identify faces. Face recognition smart door locks refer to the use of 3D cameras to establish millimeter-level 3D face models for users, and through living body detection and face recognition algorithms to detect and Track the features of the face and compare it with the 3D face information stored in the door lock. After face verification, the lock is unlocked, realizing high-precision identity authentication and non-inductive unlocking. [0003] Face recognition smart door locks are gradually used by users due to their high security and versatility. However, the fly in the ointment is that the power consumption of face recognition is much greater than that o...
