A fingerprint lock assembly for a smart home anti-theft door

Abstract

The invention discloses a fingerprint lock assembly of an intelligent household antitheft door. The fingerprint lock assembly of the intelligent household antitheft door comprises an outward pulling handle and a fixed handle, wherein the outward pulling handle is formed by connecting a connecting portion with a handle portion; the inner side face of the fixed handle is fixed to the outer side faceof the antitheft door; the upper end of a square shaft section is coaxially connected with the push rod lower end of a first electric push rod, and the first electric push rod is vertically installedon the top face of the fixed handle; a first impact block is fixedly arranged on the inner side face of the connecting portion and matched with a first position sensor; and a detection signal of thefirst position sensor is fed back to a first controller, and the first controller is used for controlling the first electric push rod to extend. According to the scheme, an identifying glass sheet isadjusted from the fixed mode to the movable mode and from the inclined exposure mode to the vertical hiding mode, so that the defect that a traditional structure is prone to dust deposition is overcome fundamentally.

Description

technical field [0001] The invention belongs to the field of smart home, in particular to a fingerprint lock assembly for an anti-theft door of smart home. Background technique [0002] The anti-theft door is an important facility in the home field, and it realizes anti-theft through locks. With the promotion of the concept of smart home, a fingerprint lock has appeared on the market. This fingerprint lock is located on the outer side of the anti-theft door. The distance of the fingerprint reader is calibrated at the factory. When opening the door, people's fingers directly touch the identification glass, and the fingerprint recognition circuit in the fingerprint lock recognizes the fingerprint; after the fingerprint recognition circuit recognizes the fingerprint, the fingerprint lock is unlocked, and the person turns the door handle downward by hand to open the door. In addition, for the failure of the fingerprint lock, a password identification and key identification sys...

AI Technical Summary

Problems solved by technology

[0004] 1. Since the identification glass of the fingerprint lock is inclined upward and is set toward the outside of the door, this setting method has several serious problems as follows: a. The important identification glass is exposed, which is easy to be artificially or other factors. damage, or water reaches the fingerprint identification circuit after passing through the identification glass, thereby losing the fingerprint identification circuit and causing the fingerprint lock system to fail; Reduce the success rate of fingerprint identification; moreover, people's fingers have sweat, etc., if there is too much contact, sweat will inevitably remain on the identification glass, which will further reduce the success rate of fingerprint identification; in order to avoid dust and sweat residue, people often need to use a rag Actively wipe the identification glass, but this requires an additional operation process, which is time-consuming and laborious

[0005] 2. Due to the serious defect of the above-mentioned article 1, it is currently necessary to set up a password identification and key identification system as a backup, which not only increases the complexity and volume of the lock, but also increases the manufacturing cost, which is not conducive to market promotion

[0006] 3. When unlocking the lock, first touch the identification glass with your finger, and then unlock the lock after passing the fingerprint identification, and then turn the handle to finally open the door. Two separate steps are required, and it is inconvenient to open the door
