Diaphragm structure of automobile upright post

Abstract

The invention provides a diaphragm structure of an automobile upright post, comprising: a board body, flanging edges, a reinforcing rib and a connecting board; The flanging edges are located on bothsides of the plate body, and the flanging edged and the board body are of an integrated structure; The reinforcing rib is located in the inside of the board body, and the reinforcing rib and the boardbody are of an integrated structure; The connecting plate is arranged at the back of the board body, and is connected with the board body through welding. By improving the structure of the device, the invention has the advantages of high flexural and torsional strength, reduced impact deformation, high rigidity strength and improved impact bearing strength of a neutral column, and the like, thereby effectively solving the problems and shortcomings proposed in one item of the background technology of the invention.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, and more specifically relates to a partition structure in a column assembly in an automobile body. Background technique [0002] The center pillar of a car is one of the essential parts of the car body. It is an assembly formed by superimposing the outer plate, the partition plate, the reinforcement plate and the inner plate in sequence. The center pillar not only plays the role of support, but also plays the role of the door frame. , the most important thing is that it also plays a decisive role in the safety performance of the car after being subjected to side impact. [0003] However, due to the incomplete design and structure of the partition plate in the center column assembly, the bending and torsional strength is poor, resulting in that the impact resistance of the center column cannot be improved, and it lacks a certain rigidity. It is very easy to cause its own deformat...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide an automobile column partition structure, to solve the above-mentioned background technology because the design structure of the partition in the current center column assembly is still not perfect, resulting in poor bending and torsional strength, resulting in The impact resistance of the column cannot be improved, and it lacks a certain rigidity, which can easily lead to its own deformation and affect the welding accuracy and other problems and deficiencies.
