Embodiment 1

[0030] Such as image 3 As shown, the locked gear step has two stages, one of which is a half-lock gear step 12, and the other is a full-lock gear step 13. When the lock hook 14 is in the locked position, The full-lock gear step 13 and the retaining edge of the pawl 2 fit; when the lock hook 14 is between the locked position and the unlocked position, the half-lock gear step 12 and the stop pawl 2 Fit the ribs.

[0031] Two steps are processed on the chuck 1, namely the half-lock gear step 12 and the full-lock gear step 13, and the edge of the stop claw 2 corresponding to the chuck 1 is processed to a certain arc to ensure the travel of the chuck 1. A new lock body mechanism is formed by the processed card plate 1 and the stop claw 2 to realize the two gears of the lock body full lock and half lock.

[0032] According to the structure provided by this embodiment, when the lock body is fully locked, the clamping plate 1 and the stop pawl 2 are engaged at the full-lock gear step 13, ...

Embodiment 2

[0035] Such as image 3 As shown, the direction of the contact surface of the locking gear step and the rib of the stop pawl 2 is the radial direction toward the center of rotation of the card plate 1.

[0036] The above-mentioned structure ensures that the stop pawl 2 and the clamping plate 1 can easily enter into engagement, and can also be easily disengaged.

Embodiment 3

[0038] The outer edge of the card plate 1 located between the half-lock gear step 12 and the full-lock gear step 13 is a circular arc concentric with the center of rotation.

[0039] The above-mentioned structure enables the pawl 2 to slide in a balanced manner on the arc of the edge of the chuck 1 when the chuck 1 is rotating, and the resistance is small.

Abstract

The invention discloses an automobile door lock, wherein, a clipping board (1) is attached to the rib of a locking claw (2) through lock position steps, the lock position steps are multilevel steps distributed around a circle taking the rotation center of the clipping board (1) as the centre of a circle. Through adopting the technical proposal, the security of the automobile door lock is improved, when an automobile is in an accident, a lock body is impacted by great impact force, the automobile door lock can prevent the automobile door from opening, which significantly reduces danger that passengers are thrown out of a passenger compartment; the appearance of the lock body does not need to be changed, one or a plurality of lock positions are added based on the prior lock body, the functions of the invention can be realized through changing the parts in the lock body, which can not affect the lock body arrangement on the automobile door, assembly technology performance, and interchangeability and general performance.

Description

Technical field [0001] The present invention belongs to the technical field of automobile structure, and relates to automobile body structure. More specifically, the present invention relates to an automobile door lock, particularly an automobile door lock mainly used on the back door of an automobile. In addition, the present invention also provides a method for locking and unlocking the aforementioned automobile door lock. Background technique [0002] The locking structure of the automobile back door lock includes a clamping plate, a stop claw and an opening arm, which are all rotating components. A tension spring is provided between the stopping pawl and the clamping plate to tighten the two. The stopping pawl is tightly attached to the clamping plate through the rib structure to keep the lock hook provided on the clamping plate in the locked position. The rotation of the opening arm pushes the stop pawl to rotate through the push pin provided on the opening arm, and the stop...
