Motor direct-driven transmission device of door lock and intelligent door lock

Abstract

The invention discloses a motor direct-driven transmission device of a door lock and an intelligent door lock. The motor direct-driven transmission device mainly comprises an inner door panel, a bottom plate, a lock core, a shifting strip and components like an unlocking rotary knob, a driving bevel gear, a gear motor, a motor bevel gear, an optoelectronic switch, an optical grating coding disc, a buffer cushion and a locking cover. According to the motor direct-driven transmission device, the lock core is driven to rotate through the gear motor, automatic locking and unlocking functions of an electronic door lock are achieved through utilizing a traditional mechanical lock body, and the motor direct-driven transmission device has the advantages that the changing and mounting are easy, the cost is low, the operation is stable, reliable, safe and convenient, the device is abrasion resistant, the noise is low, and the service life is long, integrates convenience of an intelligent lock and safety and reliability of a mechanical lock, and has wide application prospect in the field of intelligent door locks.

Description

technical field [0001] The invention relates to a motor direct drive transmission device, in particular to an intelligent door lock based on the motor direct drive transmission device and an automatic locking and unlocking method thereof. Background technique [0002] With the advancement of electronic technology, more and more electronic locks, which are safer and more convenient than mechanical locks, have entered thousands of households. The existing electronic lock mainly adopts an electronic lock body with a built-in clutch mechanism. Refitting needs to replace the original mechanical lock body with an electronic lock body, and the refitting process is complicated. [0003] The existing method to solve this kind of problem is to install a clutch separately outside the lock body, so that the installation process of the lock body is simple and convenient. Usually, the clutch function is realized by pressing the pin of the clutch, but because the pin pressing device can mo...

AI Technical Summary

Problems solved by technology

The existing electronic lock mainly adopts the electronic lock body with a built-in clutch mechanism. The modification needs to replace the original mechanical lock body with the electronic lock body, and the modification process is complicated.

[0003] The existing method to solve this kind of problem is to install a clutch separately outside the lock body, so that the installation process of the lock body is simple and convenient. Usually, the clutch function is realized by pressing the pin of the clutch, but because the pin pressing device can move as a whole, the stability is poor , there are defects such as easy jamming, poor anti-theft and anti-prying performance

[0004] In the prior art, the smart door locks that automatically unlock and lock mostly use a large number of gears and linkage mechanical structures, and have defects such as low mechanical transmission efficiency, large space occupation, easy wear and tear, and reduced service life of smart locks.
