Steel-plastic composite support assembly for automobile instrument panel and automobile

Abstract

The invention discloses a steel-plastic composite car instrument panel bracket assembly and an automobile, wherein the bracket assembly includes a steel beam, the two ends of the beam are respectively provided with body mounting brackets, and the bracket assembly also includes at least a connecting bracket for connecting the floor , IP bracket for installing instrument panel, air conditioning bracket for installing air conditioner, PEPS module bracket for installing PEPS module and glove box bracket for installing glove box, connecting bracket, IP bracket, air conditioning bracket, PEPS module bracket 1. All or part of the glove box bracket is an injection molded part made of plastic mixed with nylon and glass fiber. This patent replaces steel parts with plastic injection parts, which can effectively reduce the weight of the automobile instrument panel bracket assembly. At the same time, through the selection of plastic materials, the rigidity and other properties of each injection part can be improved, which can effectively realize light weight. Combined with improving the modal, stiffness and strength properties of the entire automotive dashboard bracket assembly, the NVH performance is improved.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a steel-plastic hybrid automobile dashboard bracket assembly and automobiles. Background technique [0002] The car instrument panel bracket assembly is an important load-bearing mechanism on the car. It is the inner skeleton of the instrument panel system and supports the instrument panel system. It is used to install the instrument panel, airbag, steering system, etc. The connecting bracket of the assembly also plays a certain role in increasing the strength of the entire body. [0003] As "energy saving and environmental protection" has become a topic of more and more attention to the whole society, lightweight is not only conducive to improving handling but also has excellent fuel-saving performance, so it is also widely used in the field of ordinary cars. [0004] At present, the instrument panel bracket assembly of a small car is generally made of steel sheet metal parts and / or ...

AI Technical Summary

Problems solved by technology

[0007] The traditional instrument panel bracket assembly, due to its complex structure, is often a plate shell structure stamped from a large number of steel plates with a material thickness between 1.0mm and 3mm, and then assembled by welding assembly technology. During the welding process, it is extremely It is easy to cause large welding deformation of steel parts, which affects the tolerance level of the instrument panel bracket assembly and the stability of production quality

[0008] Finally, due to the welding process, once the welding is formed, when a certain part is deformed or damaged, it cannot be repaired by replacing the corresponding part alone, and the instrument panel bracket assembly needs to be replaced as a whole, which results in a high maintenance cost. further increase
