Automobile tail door lock with emergency release rod

Abstract

The invention discloses an automobile tail door lock with an emergency release rod. The automobile tail door lock comprises the emergency release rod hinged to a hood cover through a shaft and a firstcircular column arranged on the hood cover and abutting against an elastic strip of the emergency release rod, wherein the elastic strip of the emergency release rod is in a circular arc shape, the free end of the elastic strip bends towards an emergency release rod body, the elastic strip continuously extends from a root portion starting point to the end face of the free end and from thick to thin, the automobile tail door lock further comprises a second circular column arranged on the hood cover and used for abutting against the elastic strip of the emergency release rod, the circle centerof the second circular column is inside the side line, close to the emergency release rod body, of the plumb line of the circle center of the first circular column, and in an assembly state, a gap exists between the outer circumferential surface of the second circular column and the elastic strip. The automobile tail door lock is good in mechanical performance, under the same motion stroke, the deformation quantity is reduced, the phenomenon of the elastic strip being broken by pressing is avoided, and the second circular column limits the deformed outline of the elastic strip, so that smoothresetting of the emergency release rod is basically guaranteed.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to an automobile tailgate lock with an emergency release lever. Background technique [0002] The automobile tailgate lock of the prior art is a very mature technology. After the electric motor in the electrical base is energized, the release plate is driven to the left or right by the worm and the worm gear, and the coaxial lock in the base is driven to the left or right. The release lever and pawl turn to disengage the ratchet, which unlocks the tailgate. [0003] But the tailgate lock of the above prior art still has the following deficiencies: 1. The emergency release lever body hinged on the electrical base and the elastic strip of the emergency release lever are generally plastic materials and the elastic strips are not connected to each other in order to save costs. The outside of the part extends in a straight line away from the body of the emergency release lever. In pr...

Problems solved by technology

[0003] But the tailgate lock of the above prior art still has the following deficiencies: 1. The emergency release lever body hinged on the electrical base and the elastic strip of the emergency release lever are generally plastic materials and the elastic strips are not connected to each other in order to save costs. The outside of the part extends in a straight line away from the body of the emergency release lever. In practical applications, the deformation is relatively large, especially under low temperature conditions, and the elastic strip is often broken, which also affects the function and safety reliability of the tailgate lock.

2. After the elastic strip of the emergency release lever is pressed, its reset is not smooth or even automatically reset

3. The worm gear shaft is only installed in the electrical base, and the positioning effect of the worm gear is not ideal in actual use
