Front body structure and car

Abstract

The present disclosure provides a front structure of a vehicle body, the front structure of the vehicle body comprising: a front side member assembly, including: a front side member inner panel, a front side member cover plate and a front side member support plate, the front side member inner panel The panel includes a longitudinal beam bottom plate and two longitudinal beam side panels on opposite sides of the longitudinal beam bottom plate, both of the longitudinal beam side panels are connected to the front longitudinal beam cover plate and the front longitudinal beam cover plate Opposite to the longitudinal beam bottom plate, a part of the front longitudinal beam support plate is located in the groove enclosed by the longitudinal beam bottom plate and the longitudinal beam side plate, and the front longitudinal beam support plate is located in the groove The part is connected with the longitudinal beam bottom plate and the longitudinal beam side plate, and the plate surface of the front longitudinal beam support plate is connected with the side edge of the front longitudinal beam cover plate; the front wheel house side reinforcement beam is connected with The parts of the front side member support plate outside the groove are connected. The present disclosure can improve the energy absorption effect of the front structure of the vehicle body and reduce the deformation amount of the passenger compartment.

Description

technical field [0001] The present disclosure relates to the technical field of automobiles, and in particular, to a vehicle body front structure and an automobile. Background technique [0002] 25% small offset collision has attracted more and more attention. In this type of collision, the amount of overlap between the obstacle and the front of the body is small, and only 25% coverage can only cover the area of ​​the front wheel cover outside the front longitudinal beam. The longitudinal beam does not participate in the collision, and the front longitudinal beam cannot absorb the collision energy, which makes the body's anti-collision performance poor. [0003] In the related art, the solution to deal with 25% small offset collision is mainly to add connecting pieces to the side walls of the front longitudinal members, and connect the reinforcing beams on the side of the front wheel house to the connecting pieces, so as to strengthen the side of the front wheel house throug...

Problems solved by technology

[0002] The 25% small offset collision has attracted more and more attention. In this type of collision, the frontal overlap between the obstacle and the vehicle body is small, and the coverage is only 25%, which can only cover the front wheelhouse area outside the front longitudinal beam, resulting in The longitudinal beam does not participate in the collision, and the front longitudinal beam cannot absorb the collision energy, which makes the impact resistance of the body poor

[0004] However, when the vehicle body structure in the related art responds to a 25% small offset collision, since the connecting piece is connected to the outer side wall of the front longitudinal beam, when the collision impact is received, the outer side wall connected to the connecting piece on the front side beam is partially The force is large, so it is easy to pull the front longitudinal beam, resulting in bending of the front longitudinal beam, and then making the force transmission of the front longitudinal beam invalid
