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

Abstract

The invention discloses a steel-plastic composite support assembly for an automobile instrument panel (IP) and an automobile. The steel-plastic composite support assembly comprises a cross beam made of steel, wherein vehicle body mounting supports are respectively arranged at two ends of the cross beam. The steel-plastic composite support assembly also at least comprises a connection support for connecting the support assembly with a floor, an IP support for mounting the automobile IP, an air conditioner support for mounting an air conditioner, a PEPS module support for mounting a PEPS moduleand a glove box support for mounting a glove box, wherein all or part of parts of the connection support, the IP support, the air conditioner support, the PEPS module support and the glove box supportare injection molded parts made of plastic obtained by mixing nylon and glass fiber. The steel-plastic composite support assembly for the automobile IP uses the plastic injection molded parts insteadof steel parts to effectively realize the lightweight of the support assembly for the automobile IP. At the same time, by virtue of the selection of plastic material, the steel-plastic composite support assembly improves the rigidity and other performance of each injection molded part, effectively realizes the lightweight, improves the combination of modality, rigidity and strength performance ofthe entire support assembly for the automobile IP, and improves the NVH performance.

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
