Description
Technical Field
[0001] The invention relates to the technical field of door lock suction and disengagement and ice-breaking unlocking, and in particular to a door lock suction and suction interruption mechanism. Background Art
[0002] At present, in the field of door locks, it is common to realize the suction and disengagement of door locks, but it is still a very rare function to realize mechanical and electric suction and disengagement at the same time. At present, in the process of suction and disengagement of door locks, the manual operation force is large, the noise is large, and it is easy to have a situation of unsmooth disengagement. For example, the published patent 2007800417412 discloses a locking mechanism for vehicles, whose structure is to lock through the cooperation of the pre-stop and the main stop on the lock tongue and the pawl to achieve half-lock and full-lock states. However, during the operation of the above structure, due to the different positions of the mirror image spacing of the pre-stop and the main stop, two jumps will be generated when the pre-stop and the main stop are respectively in contact with the lock tongue, thereby generating two noises. After the pre-stop completes the stopping work, it needs to push a larger angle before the pre-stop is pushed out of the groove on the lock tongue, and the main stop can enter the groove on the lock tongue. Its movement trajectory needs to be more extreme. At the same time, multiple jumps are also a great test for the wear degree of the product. Summary of the invention
