Automobile front longitudinal beam reinforcing component

Abstract

The invention belongs to the technical field of automobiles and specifically relates to an automobile front longitudinal beam reinforcing component. In order to improve the automobile body manufacturing convenience and automobile body dimension stability on the premise of guaranteeing the automobile body performance, the automobile front longitudinal beam reinforcing component comprises a front longitudinal beam connecting bracket and a front longitudinal beam torsion box component; the front longitudinal beam connecting bracket is used for connecting an automobile front longitudinal beam withan automobile A pillar; an automobile waterproof wall is connected to the internal side of the front longitudinal beam connecting bracket; a front longitudinal beam torsion box at least comprises a first internal plate; a first side of the first internal plate is connected to the internal side of the automobile A pillar; a second side of the first internal plate is connected to the internal sideof the automobile waterproof wall; and furthermore, the front longitudinal beam torsion box component further comprises a first external plate positioned on the external side of the automobile waterproof wall and a second external plate integrally molded with the first external plate or connected to the upper end surface of the first external plate. According to the automobile front longitudinal beam reinforcing component, on the premise of satisfying collision performance requirements, the lightweight purpose is furthest achieved, and the stability of automobile body dimension can be effectively controlled.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and in particular relates to an automobile front longitudinal beam reinforcement assembly. Background technique [0002] As the requirements for automobile manufacturing precision are getting higher and higher, it has become a major technical problem in this field to improve the convenience of vehicle body manufacturing and the dimensional stability of the vehicle body under the premise of ensuring the performance of the vehicle body. At present, the torsion box at the front of the car body (the structure at the front side beam and the door sill) adopts a casting structure. During assembly, the casting is usually aligned in the Y direction with the A-pillar inner panel (the A-pillar inner panel is currently also designed as a casting) or It is a local boss fit, because the surface profile of the casting is in the process, that is, the size control ability cannot be well guaranteed, so the coo...

At present, the torsion box at the front of the car body (the structure at the front side beam and the door sill) adopts a casting structure. During assembly, the casting is usually aligned in the Y direction with the A-pillar inner panel (the A-pillar inner panel is currently also designed as a casting) or It is a local boss fit, because the surface profile of the casting is in the process, that is, the size control ability cannot be well guaranteed, so the cooperation between the casting and the casting is very easy to make the body Y direction wider than the nominal value, resulting in instability of the body size. Indirectly affect problems such as large door closing force and door sealing performance during vehicle assembly and matching
