Technical Field

[0001] The present invention relates to the technical field of latch locks, and in particular to a locking and unlocking mechanism. Background Art

[0002] Mechanisms that implement locking through the interaction of a latch and a latch hole are widely used in various applications. Typically, these locking mechanisms only offer automatic locking / unlocking or manual locking / unlocking functions. However, when such locking mechanisms are applied to complex machinery, such as aerospace, vehicles, and elevators, they require both automatic locking / unlocking and manual locking / unlocking functions to prevent power failure.

[0003] On the other hand, this type of locking mechanism is difficult to integrate with the related structures of the complex machinery to which it is applied, that is, it requires an additional, separate motor to perform the locking action, which takes up a large space. Summary of the Invention

[0036] Furthermore, as a preferred embodiment, the latch 2 includes: a protruding structure 24, which is preferably arranged on or at the latch platform 22, and has a latch bevel portion 241 facing away from the latch hole 1, and the latch bevel portion 241 forms a latch abutment portion.

[0037] It should be noted that the protruding structure 24 only needs to provide the latch bevel portion 241 . It is not limited to being a protruding structure, nor is it limited to being located on the latch platform 22 . It can also be provided on the peripheral structure of the latch platform 22 .

[0038] As another preferred embodiment, the latch 2 includes a latch bevel portion 241 . The latch bevel portion 241 is disposed opposite to the latch hole, and forms a latch abutment portion.

[0039] Preferably, the upper end of the latch bevel portion 241 is disposed away from the latch hole 1, and the lower end of the latch bevel portion 241 is disposed close to the latch hole 1, thereby forming an inclined surface. The inclined surface of the latch bevel portion 241 can be a flat surface or a curved surface.

[0040] Furthermore, as a preferred embodiment, the driven rotating block 4 is located on one side of the latch 2, and the surface of the driven rotating block 4 on the side facing the latch 2 extends outward to form a columnar structure 41, and the columnar structure 41 has a columnar structure arc surface portion 411, and the columnar structure arc surface portion 411 forms a first abutting portion.

[0041] Preferably, since the driven rotating block 4 rotates around the driven rotating shaft 44, the movement trajectory of the columnar structure 41 located thereon is an arc.
