Automobile and reinforcing device for inner plate of rear wheel casing of automobile

Abstract

The invention provides an automobile and a reinforcing device for an inner plate of a rear wheel casing of the automobile, and relates to white bodies of automobiles. The reinforcing device for the inner plate of the rear wheel casing of the automobile is characterized in that an inner plate of a C column is connected to the upper portion of the reinforcing device, a crossbeam of a rear seat and a rear crossbeam of a rear floor are connected to the lower portion of the reinforcing device, the reinforcing device is supported on the inner plate of the rear wheel casing, the reinforcing device for the inner plate of the rear wheel casing of the automobile comprises a support plate for the inner plate of the rear wheel casing and a double-arm reinforcing plate for the inner plate of the rear wheel casing, and the support plate for the inner plate of the rear wheel casing is connected with the inner plate of the C column and is supported on the inner plate of the rear wheel casing; the double-arm reinforcing plate for the inner plate of the rear wheel casing is connected with the support plate for the inner plate of the rear wheel casing and is provided with a front reinforcing arm and a rear reinforcing arm, the front reinforcing arm and the rear reinforcing arm are supported on the inner plate of the rear wheel casing, the front reinforcing arm is further connected onto the crossbeam of the rear seat, and the rear reinforcing arm is further connected onto the rear crossbeam of the rear floor. The automobile and the reinforcing device have the advantages that the Y-direction dynamic and static stiffness of the automobile and the stiffness of a C ring of a body of the automobile can be improved, and the reinforcing device is applicable to manufacturing the white body of the automobile.

Description

technical field [0001] The invention relates to an automobile body in white, in particular to an automobile rear wheel house inner plate reinforcing device and the automobile. Background technique [0002] With the rapid development of the automobile industry and technology, people have higher and higher requirements for the safety, comfort and durability of automobiles. [0003] In the prior art, a rear wheel house inner panel reinforcement plate is designed in the body shell, and the upper part of the inner reinforcing plate and the outer reinforcing plate are respectively welded on the inner and outer sides of the rear wheel house inner panel, and the upper part of the inner reinforcing plate is connected to the inner reinforcing plate. The lower part of the plate is connected, thereby realizing the three-layer plate welding of the inner and outer reinforcement plates and the inner plate of the rear wheel house, which ensures the strength of the installation point of the ...

AI Technical Summary

Problems solved by technology

[0004] But even so, there are still certain defects in the structural design of the existing rear wheel house inner panel reinforcement plate. Due to this defect, the Y-direction dynamic and static stiffness of the car is still low, and it is still easy to appear due to the stiffness of the shock absorber installation point. Problems such as roaring and tire noise in the car caused by insufficient car body; and the rigidity of the C-ring of the car body is still weak, and the torsional rigidity of the car body is still insufficient, thus affecting the durability and safety of the car
