Vehicle door lock pin reinforcer, vehicle door assembly and vehicle

Abstract

The invention discloses a vehicle door lock pin reinforcer, a vehicle door assembly and a vehicle. The vehicle door lock pin reinforcer comprises a reinforcer body with a Z-shaped cross section, wherein the reinforcer body comprises a lower transverse plate, a vertical plate and an upper transverse plate which are connected in sequence, the lower transverse plate and the upper transverse plate are in lap joint with a vehicle body, the front side of the vertical plate is fixedly connected with a lock catch nut plate; the front side of the vertical plate is provided with a limiting hole correspondingly matched with a limiting clamp on the edge of the upper end of the lock catch nut plate, and a movement allowance is reserved between the limiting clamp and the hole wall of the limiting hole. On the basis of ensuring rigidity and strength, poor attachment of the lock catch nut plate and the lock pin reinforcer can be avoided, so that the assembly quality of the lock catch nut plate is improved.

Description

AI Technical Summary

Problems solved by technology

[0004] Although the above application has solved the requirements for the sound quality and stiffness of the door opening and closing, when the lock nut plate is welded with this structure, due to the poor matching between the lock nut plate and the lock pin reinforcement, the installation surface of the lock nut plate is not in contact with the lock pin. The installation surface of the pin reinforcement is tilted, or when the lock pin stud is installed, the force in the vertical direction of the bolt will cause the lock nut plate to move in the opposite direction to the fitting surface, thereby affecting the installation position of the lock pin nut buckle, resulting in There is a door lock matching problem

At the same time, when the NVH is lifted, the cross-sectional cavity formed by the lock pin reinforcement and the bulge is relatively large, which is not conducive to the sealing of the expansion rubber

And due to the lack of reinforcement structure, there is a problem of rebound deformation after the lock pin reinforcement is formed
