The catch lever stop surface 320 may be disposed at either the upper end or the lower end of the catch lever 300, and this embodiment is described as a case where the catch lever stop surface 320 is disposed at the upper end of the catch lever 300.
A first limiting elastic assembly 600 and a second limiting elastic assembly 700 are further disposed in the lock case 100, and one end of the first limiting elastic assembly 600 corresponds to the unlocking stop portion 322 and the locking stop portion 323 respectively. The other end of the first spacing elastic component 600 is in spacing fit with one end of the second spacing elastic component 700, the other end of the second spacing elastic component 700 is connected with one end of the shape memory alloy part 800, and the other end of the shape memory alloy part 800 is a fixed end. The power module 400 is electrically connected to the shape memory alloy member 800, and the power module 400 is connected to the shape memory alloy member 800 via the wires 1 and 2 and the wiring board 500 is connected to the power module 400.
Preferably, the first limiting elastic assembly 600 in this embodiment includes a first ejector rod 610 and a first compression spring 620 sleeved on the first ejector rod 610, wherein one end of the first compression spring 620 is a fixed end, and the other end of the first compression spring is matched with a limiting step 611 on the first ejector rod 610. The second limiting elastic assembly 700 comprises a second ejector rod 710 and a second compression spring 720 sleeved on the second ejector rod 710, wherein one end of the second compression spring 720 is a fixed end, and the other end of the second compression spring 720 is matched with a limiting step 711 on the second ejector rod 710. The first push rod 610 and the second push rod 710 are perpendicular to each other, and the other end of the second push rod 710 is connected to one end of the shape memory alloy member 800. The shape memory alloy member 800 is a shape memory alloy wire, but may be a spring made of a shape memory alloy material or a strip made of a shape memory alloy material.
In order to control the rotation range of the hook lever 300, a limiting edge 120 for limiting the excessive rotation of the hook lever 300 is further disposed in the lock case 100.
To increase the amount of deformation of the shape memory alloy member 800, the shape memory alloy member 800 is turned around by at least one pulley 130 disposed within the lock housing 100.
