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...
