A structure of the side member wheel house area to improve the front impact performance

Abstract

The purpose of the present invention is to propose a structure of the longitudinal beam wheel housing area of ​​the automobile, the structure of the longitudinal beam wheel housing area of ​​the automobile of the present invention comprises the front longitudinal beam and the rear part assembly of the front wheel housing side reinforcing beam, the key is, also It includes a connecting member, the connecting member is formed by fixedly connecting the reinforcing beam and the front assembly of the front wheelhouse side reinforcing beam, the reinforcing beam is embedded in the front end of the front longitudinal beam, and is fixedly connected with the front longitudinal beam, the The front wheelhouse side reinforcement beam front assembly and the front wheelhouse side reinforcement beam rear assembly are located on the same straight line along the vehicle body length direction and are fixedly connected. Connecting the front part of the front longitudinal beam to the rear assembly of the front wheel house side reinforcement beam through the connecting member can make the front wheel house side reinforcement beam participate in the front collision process, and the connection member can effectively transmit the front collision force to the wheel house area For the side reinforcement beam, the rear assembly of the side reinforcement beam of the front wheel house is used as the transmission and energy absorption path of the front impact force, so as to reduce the intrusion of the baffle and reduce the degree of occupant injury.

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
