Car vertical column structure

Abstract

The invention discloses a car vertical column structure comprising a column body inner plate, a side outer plate, an air conditioner pipeline and a foaming assembly. A plurality of mounting positions are arranged on the column body inner plate. The side outer plate is fixed to the column body inner plate, and a cavity is limited between the side outer plate and the column body inner plate. The air conditioner pipeline is formed in the cavity, is a metal piece or a composite material piece and is provided with a plurality of ventilation openings corresponding to the multiple mounting positions. The foaming assembly is arranged on the peripheral wall of the air conditioner pipeline and comprises a foaming piece. After the air conditioner pipeline is pre-mounted on the inner wall of the cavity, the foaming piece foams so as to fill other gaps of the cavity. According to the vertical column structure, the air conditioner pipeline can serve as a reinforcing piece of the cavity, and the cavity is filled with the foaming piece, so that the vehicle-interior quiet performance and the taking comfort of a passenger are improved, the anti-collision performance, rigidity and strength of the cavity are improved, and the utilization rate of the overall space can be increased.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to an automobile column structure. Background technique [0002] In the A-pillar of an existing automobile, the cavity formed by the tailor-welding of the side wall outer panel, the inner panel, and the reinforcing plate is basically empty, resulting in a waste of overall space. Moreover, if this kind of A-pillar structure wants to achieve high strength and obtain a good impact protection effect, the thickness of the reinforcement plate and the inner plate sheet metal parts will often be relatively thick and heavy. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. Therefore, the present invention proposes a column structure of an automobile. The air-conditioning duct can be used as a reinforcement of the cavity to improve the anti-collision performance and rigidity of the cavity, improve th...
