Vehicle and body structure thereof

Abstract

The invention provides a vehicle and a body structure thereof, the body structure comprises a front anti-collision beam (6), a front longitudinal beam and a connecting plate connecting the front anti-collision beam (6) to the front longitudinal beam; the body structure also includes: an extension structure used for being connected with a top side beam (10) of a front wheel cover; a reinforcement piece (9) connecting the extension structure to the connecting plate; wherein, the reinforcement piece (9) is connected with the front longitudinal beam. The body structure disperses the impact force in high-speed collision, effectively reduces the deformation degree of the front longitudinal beam, reduces the impact effect, and then reduces the deformation of the passenger compartment of the vehicle. In addition, the impact force can still be transmitted to the top beam of the front wheel cover through the connecting plate, the reinforcement piece and the extension structure when the collisionposition is on the outside side of the front longitudinal beam, and the impact force is transmitted to the front longitudinal beam through the reinforcement piece, and the energy absorption failure can be effectively avoided and the safety can be improved.

Description

technical field [0001] The invention relates to the technical field of vehicle equipment, in particular to a vehicle and its body structure. Background technique [0002] At present, there is only one transmission path for the impact force of a 25% small offset collision, that is, the direction of the impact force passes through the front anti-collision beam-energy-absorbing box-front anti-collision beam mounting plate-front anti-collision beam front cover-front longitudinal Beam and front longitudinal member outer panel. [0003] During a high-speed collision, a large deformation of the front longitudinal beam may be caused, resulting in a relatively serious collision effect, and serious deformation of the passenger compartment of the vehicle. Moreover, during a 25% small offset collision, since the direction of the collision in the regulations is 25% of the vehicle width, when the collision position is on the outer side of the front side beam, the energy absorption of the...

Problems solved by technology

[0003] During a high-speed collision, it may cause a large deformation of the front longitudinal beam, resulting in a more serious collision effect, which makes the deformation of the vehicle's passenger compartment serious

Moreover, during a 25% small offset collision, since the direction of the collision in the regulations is 25% of the vehicle width, when the collision position is on the outer side of the front side beam, the energy absorption of the front side beam will fail, and the front side beam The longitudinal beam cannot be effectively crushed and deformed, resulting in the failure of the front longitudinal beam to fully absorb energy during a collision, resulting in failure of energy absorption
