smart door lock

Abstract

The invention discloses an intelligent door lock, which comprises a housing, in which a driving gear, a main deadbolt, a lock cylinder and a motor are arranged, and the housing is provided with a dial gear for rotation on one side of the main deadbolt, The outer wall of the lock cylinder is provided with a lock cylinder dial tooth, and the lock cylinder dial tooth is meshed with the tongue gear, and the tongue gear is also coaxially connected with a first follower and a second follower. The first follower is fixedly connected to the tongue gear, the second follower is rotatably connected to the first follower, and a guide block and a guide block are arranged between the second follower and the first follower. A guide groove, a first driven tooth is provided on the peripheral wall of the first follower, a second driven tooth is provided on the peripheral wall of the second follower, and a clutch is also provided between the lock cylinder shifting tooth and the motor. mechanism, and a reset member is also arranged in the housing. The overall structure is simple, the transmission structure is more reasonable, the resistance of the key unlocking action is slowed down, and the smoothness of operation is improved.

Description

technical field [0001] The invention relates to an intelligent door lock. Background technique [0002] Smart door lock refers to a lock that is improved on the basis of traditional mechanical locks and is more intelligent and simple in terms of user security, identification, and management. The smart door lock is the executive component for locking the door in the access control system. Smart door locks are different from traditional mechanical locks, and are more secure, convenient, and advanced technology composite locks. Existing smart door locks are mainly unlocked through fingerprints, passwords and proximity cards. After the internal chip is processed, the control motor drives the follower to realize the unlocking action. However, in the current use process, due to the use of The motor that controls unlocking is mainly driven by gears, so that there is a large resistance between the motor and the transmission gear.

Problems solved by technology

Existing smart door locks are mainly unlocked through fingerprints, passwords and proximity cards. After the internal chip is processed, the control motor drives the follower to realize the unlocking action. However, in the current use process, due to the use of The motor that controls unlocking is mainly driven by gears, so that there is a large resistance between the motor and the transmission gear. When unlocking when the lock cylinder is driven by a key, a large force is required to complete the unlocking action, which affects customers. Experience
