Problems solved by technology

[0004] The present invention overcomes that the closed loop cannot be formed on one side of the shock absorber in the prior art, the conduction path cannot cover all the excitation points of the shock absorber, the force conduction path is not smooth, and stress concentration is easily formed in the wheel cover area. For the problem of poor integrity, a new shock absorber excitation load transmission structure is provided, which establishes a closed loop in the local area of ​​shock absorber excitation, greatly increasing the structural strength; effectively reducing the stress of the inner wheel cover under impact load

Abstract

The invention discloses a novel shock absorber excitation load conduction structure. The novel shock absorber excitation load conduction structure comprises a rear longitudinal beam, a D column innerplate, a C column inner plate, an inner wheel cover, a side wall inner plate, a shock absorber reinforcing plate and a wheel cover reinforcing plate, wherein the inner wheel cover is arranged betweenthe D column inner plate and the C column inner plate; the shock absorber reinforcing plate is arranged on the inner wheel cover; a shock absorber excitation point is arranged on the shock absorber reinforcing plate; the side wall inner plate is arranged among the D column inner plate, the C column inner plate and the inner wheel cover; the two ends of the wheel cover reinforcing plate are respectively fixed to the D column inner plate and the shock absorber reinforcing plate; and the shock absorber excitation point and the wheel cover reinforcing plate are overlapped. According to the novel shock absorber excitation load conduction structure provided by the invention, a closed loop is built in a local region of shock absorber excitation, so that the structural strength is greatly improved; and the stress of the inner wheel cover under an impact load is effectively reduced.

Description

technical field [0001] The invention relates to the field of new energy vehicle manufacturing, in particular to a novel shock absorber excitation load transmission structure. Background technique [0002] For new energy vehicles, due to the layout of the power battery, the load on the rear axle is large, and the impact load on the wheel cover area of ​​the rear shock absorber is greater than that of traditional models. Under the impact of large loads, there is a greater risk in the strength of the wheel cover. If the strength is increased by increasing the thickness of the material, a large weight cost will be paid. With the development of automobile technology, lightweight design ideas have increasingly attracted the attention of engineers. In the prior art, the load transfer path of the rear shock absorber of conventional vehicles is: shock absorber excitation point → shock absorber reinforcement plate → C-ring reinforcement plate → C-pillar inner plate. The strength of t...
