Handle type intelligent door lock

Abstract

The invention discloses a handle type intelligent door lock. The handle type intelligent door lock comprises a shell; a driving gear, a latch bolt, a square steel connecting seat, a main spring bolt and a motor are arranged in the shell; a bolt shifting gear is rotationally arranged on the shell and located on one side of the main spring bolt; driving shifting teeth are arranged on the outer wall of the square steel connecting seat and meshed with the bolt shifting gear; the bolt shifting gear is further coaxially connected to a first driven part and a second driven part, the first driven part is fixedly connected to 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 driving shifting teeth and the motor, and a reset part is further arranged in the shell. The whole structure is simple, the transmission structure is more reasonable, the resistance of the unlocking action of the handle is relieved, and the operation smoothness is improved.

Description

technical field [0001] The invention relates to a handle type intelligent door lock. Background technique [0002] The 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. The existing handle-type 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, Since the motor used to control unlocking is mainly driven by gears, there is a relatively large resistance between the motor and the transmission gear. When unlocking is driven by...

Problems solved by technology

The existing handle-type 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, Since the motor used to control unlocking is mainly driven by gears, there is a relatively large resistance between the motor and the transmission gear. When unlocking is driven by a key or a handle, it is necessary to overcome the gap between the motor and the driving gear to the driven gear. Only resistance can complete the unlocking action, which makes the force of operating the unlocking larger and affects the customer's experience
