Embodiment 1

[0029] The lock provided by Embodiment 1 does not need to add a motor and a motor driver chip, which saves production costs. By shrinking the heat-shrinkable wire and pulling the shrapnel so that the deadbolt pops out of the deadbolt groove, it can ensure that the lock can be opened normally.

[0030] At the same time, the lock can also obtain user information and compare the user information with the preset user information to obtain a similarity value. The chip will power on the heat shrinkable wire only after the similarity value is determined to be higher than the preset similarity value. After the deadbolt is ejected from the deadbolt groove, the heat-shrinkable wire is powered off, the temperature drops below the preset temperature value, the heat-shrinkable wire returns to its original length, the shrapnel returns to its original shape, and the deadbolt returns to its original position. The lock can judge whether the unlocking condition is satisfied according to the use...

Abstract

The invention discloses a lock. The lock comprises a spring bolt, an elastic sheet, a connecting piece, a heat shrinkage wire and a lock body. The spring bolt is connected with the elastic sheet. Theelastic sheet is elastic, and the elastic sheet is connected with the lock body through the connecting piece. One end of the heat shrinkage wire is connected with the elastic sheet, and the other endof the heat shrinkage wire is connected with the lock body. In the provided lock, a motor and a motor drive chip do not need to be additionally arranged, and the production cost is saved. Through shrinkage of the heat shrinkage wire, the elastic sheet is pulled, so that the spring bolt bounces out of a spring bolt groove, and it can be ensured that the lock can be normally opened.

Description

technical field [0001] The invention relates to the field of smart home, in particular to a lock. Background technique [0002] Lock is a common device in people's life, and it is widely used in doors, safes and other scenes. A lock locks a door or safe so that no one else can open it. [0003] The current electronic lock includes a controller, a motor and a motor driver chip. When the controller sends an instruction to the motor driver chip, the motor driver chip controls the motor to open the mechanical device to realize unlocking. [0004] Since this electronic lock needs to add a motor and a motor drive chip in the lock body, the volume of the motor and the motor drive chip is large, making the entire electronic lock bulky. The cost of the motor and the motor driver chip itself is relatively high. The drive of the motor requires a special algorithm and controller control, and the algorithm development and debugging cycle is long. In addition, the motor needs to coop...
