Embodiment 1

[0033] 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.

[0034] Based on the lock provided in Embodiment 1, Embodiment 2 provides a method for unlocking, such as Figure 4 As shown, the method for unlocking may include:

[0035] 201. The heat-shrinkable wire is energized and shrunk.

[0036] The heat shrinkable wire is energized, the temperature rises to the preset temperature value, and heat shrinkage occurs. The preset temperature value is preset and is the temperature value when the heat shrinkable wire shrinks.

[0037] 202. The heat-shrinkable wire shrinks and pulls the shrapnel, so that the shrapnel elastically deforms.

[0038] After the heat-shrinkable wire shrinks, the length becomes shorter, which will give a pulling force to th...

Embodiment 2

[0041] Embodiment 2 provides a method for unlocking, which may include: shrinking the heat-shrinkable wire; shrinking the heat-shrinkable wire to pull the elastic piece, so that the elastic piece elastically deforms; the elastic piece pulls the bolt, and the bolt pops out from the groove of the bolt. The lock provided by the present application does not need to add a motor and a motor drive chip, which saves the production cost. 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.

[0042] In the unlocking method provided in Embodiment 2, the lock can also obtain user information and compare the user information with preset user information to obtain a similarity value, and after determining that the similarity value is higher than the preset similarity value, the The chip will energize the heat shrinkable wire. After the bolt is ejected from the bolt groove, th...

Abstract

The invention discloses a lock and an unlocking method. The lock comprises a lock tongue, an elastic piece, a connecting piece, a thermal shrinkage wire and a lock body, wherein the lock tongue is connected with the elastic piece, the elastic piece has elasticity, the elastic piece is connected with the lock body through the connecting piece, one end of the thermal shrinkage wire is connected withthe elastic piece, and the other end of the thermal shrinkage wire is connected with the lock body. The unlocking method can comprise the steps that the thermal shrinkage wire shrinks; the thermal shrinkage wire shrinks and pulls the elastic piece, so that the elastic piece is subjected to elastic deformation; and the elastic piece pulls the lock tongue, and the lock tongue is popped out from a lock tongue slot. In the lock, no motor and motor driving chip needs to be added in, and the production cost is saved; and through the shrinking of the thermal shrinkage wire, the lock tongue can be popped out from the lock tongue slot, and it is ensured that the lock can be opened normally.

Description

technical field [0001] The invention relates to the field of smart home, in particular to a lock and an unlocking method. 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,...
