Abstract

A front longitudinal beam energy-adsorption structure for a vehicle comprises a front longitudinal beam assembly (10), the front longitudinal beam assembly (10) comprising a body (1) and a cover plate (2). The body (1) has a U-shaped structure and is provided with a body upper wing (11), a body inner side wing (12), a body lower wing (13), and a body lower flange (14). The cover plate (2) is provided with a cover plate upper flange (21) and a cover plate outer side wing (22). One or more first L-shaped conduction structures (101) are arranged on the body (1). One side of each first L-shaped conduction structure (101) consists of convex structures (111) on the body upper wing, and the other side of each first L-shaped conduction structure (101) consists of concave structures (121) on the body inner side wing. In order to match the first L-shaped conduction structures on the body (1), second L-shaped conduction structures (102) also can be arranged at corresponding positions on the cover plate (2). The front longitudinal beam energy-adsorption structure for a vehicle has a good mechanical property, good molding processability, and good welding processability.

Description

technical field [0001] The invention belongs to the technical field of automobile engineering, and in particular relates to an energy-absorbing structure for improving the crashworthiness of automobiles, in particular to an energy-absorbing structure for front longitudinal beams of automobiles. Background technique [0002] Generally, the front longitudinal beam of a passenger car extends from the front of the car body to the rear of the front floor. As a part of the body frame, it plays the role of carrying and connecting other sheet metal structural parts, and providing mounting points for related component assemblies. In addition, in terms of safety, during a frontal frontal collision, the front side beam is the main deformation energy-absorbing structure, which absorbs the instantaneous impact energy generated by the collision through plastic deformation. A good longitudinal beam structure first enables the car to have a stable crush deformation when a frontal collision ...
