Automobile front automobile body frame component

Abstract

The invention discloses an automobile front automobile body frame component which comprises a front anti-collision beam, a front wall plate, front wall plate reinforcing plates, a front crossbeam andfront girders. The front wall plate is fixed to the rear portion of the front crossbeam, the front wall plate reinforcing plates are located on the rear portions at the two ends of the front wall plate and fixedly connected with the front wall plate to form front wall plate cavities, the left end and the right end of the front crossbeam are fixedly connected with the left end and the right end ofthe front wall plate to form closed crossbeam cavities, the front and back positions of the crossbeam cavities and the front wall plate cavities correspond to each other, the rear ends of the front girders are longitudinally fixed to the front portions of the left end and the right end of the front crossbeam, and the front anti-collision beam is fixed between the front ends of the front girders onthe left side and the right side. By the adoption of the provided automobile front automobile body frame component, the matching accuracy of the front crossbeam and the front girders, the material use rate, the stamping forming quality and the collision performance of a front automobile body can be improved, the intrusion amount of installation regions of the front wall plate and pedals is reduced, and the manufacturing difficulty and the part cost are reduced.

Description

technical field [0001] The invention relates to the technical field of automobile front body, in particular to an automobile front body frame assembly. Background technique [0002] At present, on the front body of a traditional passenger car, the frame structure is usually formed by arranging the front frame 5 on both sides, and setting the front anti-collision beam 1 and the front cross member 4 between the front frame 5, and then the front cross member 4 The dash panel 2 is arranged on the vehicle frame at the rear, so that the front girder 5, the front cross member 4 and the dash panel 2 are connected by a welding process, so that the front body forms a frame-type cavity structure to enhance the stability of the front body. Crash performance and load carrying capacity. [0003] Figure 1-8 It is a schematic diagram of the joint structure of the common front frame and dash panel. The existing front body assembly has the following disadvantages: the thickness of the dash...

AI Technical Summary

Problems solved by technology

The existing front body assembly has the following disadvantages: the thickness of the dash panel 2 is thin, resulting in a relatively weak rigidity in the area of ​​the wheel housing of the dash panel 2, and the size of the cavity is limited by the envelope layout space of the pedals and tires, which is not conducive to improving the installation of the pedals. Regional crash performance

It is difficult to match the front beam 4 and the front beam 5
