a passenger car body

Abstract

The invention relates to a passenger car body which comprises a car frame. A left side wall stand column, a right side wall stand column, a roof crossbeam and a chassis crossbeam of the car frame are fixedly connected on the corresponding transverse section to form a plurality of transverse closed-loop structures. A front windshield upper crossbeam, a driver window upper longitudinal beam, a passenger car door upper longitudinal beam, a side window lower longitudinal beam and a rear cabin door upper crossbeam are fixedly connected on the horizontal section of the car body to form a longitudinal closed-loop structure. The side wall stand columns are fixedly connected with the longitudinal closed-loop structure at all the joints. The transverse closed-loop structures and the longitudinal closed-loop structure are fixedly connected together to form a whole structure, the structural strength of the upper portion of the car body is greatly improved, and the whole car frame is stressed when the car turns laterally; compared with the prior art, deformation of the car body is little, more living space is provided for passengers, the probability that the passengers escape safely is increased, and the problems that when an existing passenger car turns laterally, the safety performance of the car body is low, and personal safety of passengers inside the car cannot be better protected are solved.

Description

technical field [0001] The invention relates to passenger car bodies. Background technique [0002] With the continuous development and improvement of China's highway transportation system, the volume of highway passenger traffic and passenger turnover has increased year by year. From urban public transportation, to long-distance passenger transportation between cities, to short-distance passenger transportation in towns and rural areas, passenger vehicles are all Convenient means of transportation, passenger car traffic safety has increasingly become a topic of social concern. In the past two years, more than half of the serious traffic accidents were caused by large and medium-sized passenger cars. The front windshield upper beam, the passenger door upper longitudinal beam located above the passenger door, the driver window upper longitudinal beam located above the driver window, the rear cabin door upper beam located below the rear window, and the side windows located on ...
