AI Technical Summary

Technical Problem

The body structure of the non-load-bearing off-road vehicle is insufficient in terms of roll resistance, resulting in casualties and vehicle damage in the roll accident.

Method used

A non-load-bearing off-road vehicle anti-rolling upper body structure is designed. By setting up multiple annular frames on the side circumference assembly, top cover assembly and floor assembly of the vehicle body, including top cover beams and floor beams connected to A-pillar, B-pillar, C-pillar and D-pillar, a good force transmission path is formed to enhance the resistance to deformation of the vehicle body structure.

Benefits of technology

It significantly improves the vehicle's resistance to deformation in rolling accidents and the collision safety performance of the entire vehicle, enhances the strength of the body structure, and reduces deformation and occupant injuries during rolling.

Abstract

The invention relates to an anti-rolling upper vehicle body structure of a non-bearing type off-road vehicle, which comprises a vehicle body side wall assembly comprising a column A, a column B, a column C and a column D; the automobile body top cover assembly comprises a top cover front cross beam assembly, a skylight reinforcing ring assembly, a top cover middle cross beam assembly and a top cover rear cross beam assembly; the vehicle body floor assembly comprises a front floor front cross beam, a front floor rear cross beam, a rear floor middle cross beam and a rear coaming assembly which are sequentially arranged from front to back; the top cover front cross beam assembly and the front floor front cross beam are fixedly connected with the A column and jointly define a first annular frame. The skylight reinforcing ring assembly and the front floor rear cross beam are fixedly connected with the B column and jointly define a second annular frame. And the top cover middle cross beam assembly and the rear floor middle cross beam are fixedly connected with the column C correspondingly and jointly define a third annular frame, the top cover rear cross beam assembly and the rear coaming assembly are fixedly connected with the column D correspondingly and jointly define a fourth annular frame, and the collision and rolling safety performance of the whole vehicle is improved.
