Intelligent door lock assembly, clutch control method and intelligent door lock

Abstract

The invention relates to an intelligent door lock assembly which comprises a lock cylinder, a lock cylinder mounting block, a driving motor and a driving control panel. A driving gear is arranged at the movable end of the driving motor, the lock cylinder is installed on the lock cylinder installation block in a penetrating mode, a driven gear coaxial with the lock cylinder is arranged on the lock cylinder installation block, and the driven gear is driven by the driving gear. The driving control panel judges an unlocking instruction input from the outside and controls the driving motor to operate for unlocking when the unlocking instruction is correct, and the driving motor has a clearance in the process of driving the driving gear; according to the intelligent door lock, the driving motor with the clearance is adopted, the lock cylinder is driven in a gear transmission mode, the structural reliability is good, high unlocking torque can be transmitted, and the driving motor is controlled to rotate to the non-two-end positions of the clearance after the lock cylinder is driven to rotate in place; when the lock is unlocked, the lock can be unlocked through a key or an indoor knob, the resistance of a gear is avoided, abnormal sound also exists, the clutch structure is very simple, and the overall structure is reasonable and very compact.

Description

technical field [0001] The present invention relates to the technical field of intelligent door locks, and more specifically relates to an intelligent door lock assembly, a clutch control method and an intelligent door lock. Background technique [0002] With the improvement of people's living standards, smart door locks that are opened by fingerprints, passwords, mechanical keys, APP remotes, etc. are also popularized; [0003] Most of the smart door locks currently used have the following problems: the clutch structure of the lock body usually adopts a linear structure, which is realized by the axial clutch between the lock cylinder and the driving part. This kind of clutch structure will have more instability, and at the same time Make the lock body need to reserve enough axial margin, the lock cylinder driving torque is relatively small, poor reliability, and short service life. Contents of the invention [0004] The technical problem to be solved by the present inven...

[0003] Most of the smart door locks currently used have the following problems: the clutch structure of the lock body usually adopts a linear structure, which is realized by the axial clutch between the lock cylinder and the driving part. This kind of clutch structure will have more instability, and at the same time Therefore, the lock body needs to reserve enough axial margin, the driving torque of the lock cylinder is relatively small, the reliability is poor, and the service life is short
