Structure of longitudinal beam wheel casing area for improving front collision performance

Abstract

The invention aims to provide a structure of a longitudinal beam wheel casing area of an automobile. The structure of the longitudinal beam wheel casing area of the automobile comprises a front longitudinal beam and a front wheel casing side stiffening beam rear assembly. A connecting component is also included and is formed by fixedly connecting a reinforcing cross beam and a front wheel casing side stiffening beam front assembly. The reinforcing cross beam is embedded into the front end of the front longitudinal beam and is fixedly connected with the front longitudinal beam, and the front wheel casing side stiffening beam front assembly and the front wheel casing side stiffening beam rear assembly are located on the same straight line in the length direction of a vehicle body and are fixedly connected. The front portion of the front longitudinal beam is connected with the front wheel casing side stiffening beam rear assembly through the connecting component so that the front wheel casing side stiffening beam participates in the front collision process, the connecting component effectively transmits a front collision force to the wheel casing area side stiffening beam, and the front wheel casing side stiffening beam rear assembly serves as a front collision force transmission and energy absorption path. The purposes of reducing the invasion amount of the baffle and reducing the injury degree of passengers are achieved.

Description

technical field [0001] The invention belongs to the technical field of automobile structure, and in particular relates to the structure of the longitudinal beam wheel cover area of ​​the automobile. Background technique [0002] In a frontal collision, the front longitudinal beam of the vehicle body is the main force transmission path of the collision force, but the current structure of the longitudinal beam alone cannot fully transmit the collision force and absorb energy, and it is easy to increase the intrusion of the front fender due to insufficient absorption of the collision force. Large, which in turn leads to large deformation of the passenger compartment and increased occupant injuries. [0003] In response to the above problems, the utility model patent No. CN201220113368 proposes a car front wheel house reinforcement structure that can effectively absorb and transmit collision energy, so as to reduce the deformation of the passenger compartment caused by the bendi...

AI Technical Summary

Problems solved by technology

However, in practical applications, it is found that the transmission path of the collision force between the connecting plate and the reinforcement beam on the front wheel house cannot effectively realize the transmission of the collision force, resulting in the reinforcement beam on the front wheel house not being able to fully participate in the collision energy of the front collision transmission and absorption
