Bus side wall framework assembly structure

Abstract

The invention relates to a bus side wall framework assembly structure. The bus side wall framework assembly structure comprises multiple main uprights (1) placed in parallel from front to rear; a topcover longitudinal beam (2), a side window upper longitudinal beam (3), a side window lower longitudinal beam (4), a cabin door upper longitudinal beam (5) and a cabin door lower longitudinal beam (6)are arranged on the multiple main uprights (1) in sequence from top to bottom; multiple first supporting columns (7) are arranged between the top cover longitudinal beam (2) and the side window upperlongitudinal beam (3); second supporting columns (8) are arranged between the side window lower longitudinal beam (4) and the cabin door upper longitudinal beam (5); and a sword handle frameworks (9)are arranged in the connecting positions of the side window upper longitudinal beam (3) and the main uprights (1). According to the bus side wall framework assembly structure, the space occupied by the upper part of a bus is substantially not increased, the mounting of other parts cannot be affected, and the flexural rigidity and the non-deformability of the upper structure of the bus can be effectively enhanced; and the deformation amount of the bus during rollover can be reduced, and the survival space for passengers can be effectively guaranteed.

Description

technical field [0001] The invention relates to a side frame assembly structure of a passenger car, which belongs to the technical field of passenger cars. Background technique [0002] In recent years, with the vigorous development of my country's passenger car industry, passenger vehicles have become one of the main means of transportation for Chinese citizens to travel, and passenger vehicle accidents are the main body of serious traffic accidents. According to relevant statistics, traffic accidents caused by passenger vehicles in my country account for 40% to 50% of the total road traffic accidents. Therefore, national regulations and standards have also put forward higher requirements for the safety of passenger cars. [0003] According to relevant statistics, the number of casualties in accidents caused by passenger vehicle rollover is the highest. As far as side collision is concerned, the side of a bus is the weakest part of the car body, the side collision buffer ...

AI Technical Summary

Problems solved by technology

[0004] The side wall frame of the existing passenger car includes side window upper stringers and car window lower stringers arranged side by side at intervals along the up and down direction and extending along the front and rear directions. The roof beams are connected by multiple support columns. In order to improve the strength of the upper structure of the bus, it was usually necessary to add curved reinforcement plates on the left and right sides of the support columns. However, this method occupies a large amount of upper space of the bus and is not conducive to other The installation of decorative parts; on the other hand, the strength of the upper structure of the bus is limited, and the living space of passengers cannot be effectively guaranteed.
