Handle Smart Door Lock

Abstract

The invention discloses a handle-type intelligent door lock, which comprises a casing, in which a driving gear, an oblique bolt, a square steel connection seat, a main bolt and a motor are arranged, and the casing is located on one side of the main bolt. A dial tongue gear is provided for rotation, and a driving dial gear is provided on the outer wall of the square steel connecting seat, and the driving dial gear meshes with the dial tongue gear, and the first follower and the second tongue gear are coaxially connected to the tongue gear. Two followers, the first follower is fixedly connected to the tongue gear, the second follower is rotatably connected to the first follower, and the second follower is connected to the first follower A guide block and a guide groove are provided between them, 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 the driving tooth and the motor A clutch mechanism is also arranged between them, 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 unlocking action of the handle is slowed down, and the fluency of operation 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.

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
