Abstract

The invention discloses an automobile central channel reinforcement structure. The reinforcement structure is arranged in an automobile central channel, the reinforcement structure comprises supporting parts and a supporting crossbeam, both ends of each supporting part are connected through the supporting crossbeam, so that a closed-loop frame structure is formed, and the position of the closed-loop frame structure on the automobile central channel is aligned with a seat crossbeam of an automobile. The bearing capability of the central channel is enhanced greatly, the automobile central channel can be effectively prevented from being deformed greatly in the process of side collision, collision impact load transferred from the seat crossbeam can be transferred to the non-impacted side of the automobile body to the max, so the side collision performance of the automobile is increased, and the side-impact safety of the body of the automobile is improved.

Description

technical field

[0001] The invention relates to the technical field of automobile chassis, in particular to an automobile central channel reinforcement structure. Background technique

[0002] With the increasingly stringent automobile crash safety regulations and consumers' higher requirements for automobile safety, higher requirements are placed on the crashworthiness of automobile structures. However, in a side collision of a car, after the collision impact load is transmitted to the central channel between the two seats along the door sill and the seat beam, the central channel tends to shrink from both sides to the middle, resulting in excessive displacement and intrusion of the front seat. This could result in serious injury to the occupant.

[0003] In order to effectively solve this problem, it is usually necessary to add a strengthening structure at the position of the central passage, so that the collision load can be effectively transmitted to the non-collision s...
