Description

Technical Field

[0001] The invention relates to the field of vehicle manufacturing, and in particular to a mounting mechanism and a vehicle. Background Art

[0002] The rear side structure of a car is an important part of the car body. It needs to provide the necessary bending, torsional stiffness and strength for the entire vehicle, and will withstand the upward force applied by the rear wheel shock absorber and the downward force generated during the opening and closing of the tailgate.

[0003] The rear crossbeam assembly structure plays an important role in connecting the rear side assembly structure and the floor assembly structure. The rear crossbeam outer panel and the rear crossbeam inner panel are important components of the rear assembly structure of the automobile. How to ensure the stiffness of the connection between the two and the high dynamic stiffness of the tailgate lock installation point is very important for the stability of the rear side structure of the automobile.

[0004] In the prior art, a buckle installation reinforcement plate is usually provided in the middle of a cavity structure composed of a rear enclosure cross beam outer plate and a rear enclosure cross beam inner plate to meet the functional requirements of the buckle.

[0005] However, since the lock installation reinforcement plate in the existing mechanism is only welded to the outer panel of the rear cross beam, it is equivalent to being suspended on one side of the outer panel of the rear cross beam in the cavity structure. It cannot provide support between the outer panel of the rear cross beam and the inner panel of the rear cross beam. At the same time, welding stress is easily generated at the welding connection point, and there is a greater risk of local cracking of the beam. Therefore, it cannot meet the stiffness of the cavity structure composed of the outer panel of the rear cross beam and the inner panel of the rear cross beam and the high dynamic stiffness requirements of the tailgate lock installation point.

[0006] Based on this, the present invention is proposed. Summary of the invention
