Intelligent electric control door lock and control method thereof

Abstract

The invention discloses an intelligent electric control door lock which comprises a lock body, a lock tongue mechanism and a touch tongue mechanism. The lock tongue mechanism comprises a lock tongue and a lock tongue drive mechanism. The lock tongue drive mechanism comprises a swing arm, a lever, a first drive mechanism and a second drive mechanism. The lock tongue drive mechanism is configured with the two drive devices, each drive device is connected with the lever, and even if one of the drive devices is damaged, the other drive device can still work to complete unlocking and locking. Besides, the invention furthermore discloses an intelligent electric control door lock control method. The intelligent electric control door lock control method includes the steps that an operation instruction input by a user is received, a position signal of a front microswitch and a rear microswitch for detecting the touch tongue position is received, and the work state of the lock tongue drive mechanism is controlled according to the operation instruction and the position signal; a main drive device and a spare drive device are set; and whether the main drive device is normal or not is judged.

Description

technical field [0001] The invention relates to the technical field of intelligent locks, in particular to an intelligent electric control door lock and a control method thereof. Background technique [0002] A door lock is a device used to lock a door to prevent others from opening it. This device may be mechanical or electric, and electric power requires electrical energy. As a security product, door locks must be safe and stable. Safety can be measured from two aspects: one is to resist vandalism, malicious or deliberate prying, drilling and other violent damage. The 2nd, prevent technology from opening, and the ability of preventing technology from opening of mechanical lock is very poor. [0003] The bolt driving structure of the electronically controlled door locks on the market can be divided into two types. One is to control the expansion and contraction of a similar pin shaft mechanism through a micro-motor or electromagnet, so that the bolt is in a locked or mova...

Problems solved by technology

The second is to prevent technical opening, and the ability of mechanical locks to prevent technical opening is very poor

[0004] Of these two types, the first type still needs to use external force to turn the door handle, and has not achieved full automation.

The second type of motor directly drives the lock bolt, which requires a relatively large force, which has great restrictions on the size and quality reliability of the motor.

Moreover, the above two types have a common shortcoming. When the motor or electromagnet is damaged, it will not be possible to unlock or lock.
