Intelligent door lock

Abstract

The invention discloses an intelligent door lock. The intelligent door lock comprises a shell, a driving gear, a main spring bolt, a lock cylinder and a motor are arranged in the shell, a bolt shifting gear is rotationally arranged at the position, on one side of the main spring bolt, of the shell, lock cylinder shifting teeth are arranged on the outer wall of the lock cylinder, and the lock cylinder shifting teeth are meshed with the bolt shifting gear; the bolt shifting gear is further coaxially connected with a first driven part and a second driven part, the first driven part is fixedly connected with the bolt shifting gear, the second driven part is rotationally connected to the first driven part, and a guide block and a guide groove are arranged between the second driven part and the first driven part; and first driven teeth are arranged on the peripheral wall of the first driven part, second driven teeth are arranged on the peripheral wall of the second driven part, a clutch mechanism is further arranged between the lock cylinder shifting teeth and the motor, and a reset part is further arranged in the shell. According to the intelligent door lock, the whole structure is simple, the transmission structure is more reasonable, the resistance of a key unlocking action is relieved, and the operation smoothness 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. When unlocking when the lock cylinder is driven by ...

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
