An intelligent fingerprint combination lock and unlocking method thereof

Abstract

The invention relates to the field of intelligent fingerprint combination locks. An intelligent fingerprint combination lock includes a lock cylinder device, and the lock cylinder device includes a casing, a cross tongue assembly, a square tongue assembly, a heaven and earth rod assembly, a safety tongue assembly and a door opening and closing sensing assembly. The cross tongue assembly is located at the upper part of the casing, the square tongue assembly is located at the bottom of the cross tongue assembly, and the cross tongue assembly and the square tongue assembly are connected through a toggle rod. The safety tongue assembly is located at the lower part of the square tongue assembly, and the safety tongue assembly is an independent component. The door opening and closing sensor assembly is fixed inside the casing, and the door opening and closing sensor assembly is located between the cross tongue assembly and the square tongue assembly. This patent avoids the impact between the oblique tongue assembly and the block, prolongs the service life of the smart fingerprint combination lock, improves the safety factor of the smart fingerprint combination lock, and makes the perception of the door switch state more accurate.

Description

technical field [0001] The invention relates to the field of intelligent fingerprint combination locks, in particular to an intelligent fingerprint combination lock and an unlocking method. Background technique [0002] With the development of science and technology, all kinds of smart fingerprint combination locks are more and more widely used in life. At present, there are many ways to lock smart fingerprint combination locks. Various smart fingerprint combination locks It also has an increasingly important position. With the rapid development of the smart fingerprint combination lock industry, people pay more and more attention to the security guarantee of smart fingerprint combination locks, the perception of door status by smart fingerprint combination locks, and the service life of smart fingerprint combination locks. The use of combination locks has important implications. [0003] General smart fingerprint combination locks usually use a link mechanism to drive the...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to solve the inaccurate movement of the link mechanism in the existing fingerprint combination lock, and the internal parts of the mechanism are under a large force. The rod is deformed by force, which affects the service life of the smart fingerprint combination lock

Only set the square tongue micro switch, and sense the opening or closing state of the door by sensing the extension or contraction of the square tongue. When the door is in the open state, the extension and retraction of the square tongue cannot accurately judge the state of the door. Problem, it is proposed to drive the bolt assembly to move through the gear, and set the cross tongue stop block to press the upper end surface of the cross tongue gear bar, and rely on the friction between the cross tongue stop block and the upper end surface of the cross tongue gear bar to block the movement of the bolt tongue assembly. after exercise
