All-bearing car body structure of new-energy urban bus

Abstract

An all-bearing car body structure of a new-energy urban bus comprises a front wall assembly, a rear wall assembly, a top cover assembly, a bottom frame assembly, a support upright assembly and a closed stressed ring structure of a whole car body, wherein the closed stressed ring structure is formed by two side wall assemblies, the two ends of the support upright assembly are connected with the top cover assembly and the bottom frame assembly, so that the closed stressed ring structure is formed on the cross section of the car body conveniently, meanwhile, a two-layer frame cavity structure arranged in the top cover assembly not only facilitates the placement of energy storage equipment, but also optimizes the space in a car. According to the design, the passenger space in the urban bus is optimized, and the overall bearing uniformity of the car body structure is improved, moreover, the delivery effect of the local structure is stronger, and the closed stressed ring structure is arranged on the support upright assembly.

Description

technical field [0001] The invention relates to a full-loaded body structure of a bus, in particular to a full-loaded body structure of a new energy bus, which is particularly suitable for providing a bus with power batteries or compressed natural gas tanks and other energy storage devices arranged on the top. It has a multi-layer closed load-bearing ring structure, a three-dimensional reinforcement for the installation of the power battery pack, and a fully load-bearing body structure with a light overall weight. Background technique [0002] At present, the bus body is generally assembled and welded by six large assemblies including the front wall assembly, the rear wall assembly, the left and right side wall assemblies, the top cover assembly and the underframe assembly. According to the difference in the load bearing degree of the bus body, the bus body can be divided into three types: non-load-bearing, semi-load-bearing, and full-load-bearing. [0003] The non-load-bea...

Problems solved by technology

[0010] The purpose of the present invention is to overcome the defects in the prior art of compressing the occupant space in the bus, reducing the uniformity of the overall load bearing of the body structure, poor transmission effect of the local structure, and lack of a closed force-bearing ring design on the support column assembly To solve the problem, provide a full load-bearing new energy bus that optimizes the occupant space in the bus, improves the uniformity of the overall load bearing of the body structure, has a strong transfer effect of the local structure, and has a closed force-bearing ring design on the support column assembly.
