An openable and tightened back door lock capable of ensuring meshing performance and an assembly method

Abstract

The invention relates to the technical field of automobile part structures, in particular to a back door lock catch capable of ensuring meshing performance and being tightened in an opened state and an assembly method. The back door lock catch comprises a back panel and a lock catch. The lock catch comprises a bottom plate and a lock pin fixed to the bottom plate. A tightening face corresponding to the bottom plate is arranged in the middle of the back panel. First through holes used for fixing the bottom plate are formed in the tightening face. Second through holes corresponding to the firstthrough holes are formed in the bottom plate. The bottom plate is connected to the tightening face in the manner that the bottom plate can move in the Y direction through fastening bolts with the diameter smaller than that of the first through holes. A movement prevention structure limiting the movement of the bottom plate after the lock catch and a back door are completely meshed is arranged between the tightening face and the bottom plate. The back door lock catch is simple in structure, the lock catch and a back door lock can be positioned in a follow-up manner, meshing of the Y-direction position of the lock catch and the lock is ensured, the adjustment labor hour is reduced, the lock catch can be tightened in the opened state, and great popularization value is achieved.

Description

technical field [0001] The invention relates to the technical field of auto parts structures, in particular to an openable and tightening back door lock and an assembly method that ensures meshing performance. Background technique [0002] As the main part of the rear of the car body, the back door's position on the body directly determines the overall perceived quality of the rear. As one of the components that need to be opened frequently, the quality of the engagement between the back door lock and the buckle directly affects the performance and manipulation feeling of opening the back door. Therefore, after the back door is hinged on the top of the vehicle body, the Y-direction installation position of the back door latch is very important. [0003] At present, in the industry, the lock buckle is generally tightened directly on the lock buckle tightening surface of the back panel when the back door is opened. That is, there is no tooling positioning, nor is it self-pos...
