Vehicle side wall filling module, side wall structure and vehicle using side wall structure

Abstract

The invention relates to a vehicle side wall filling module, a side wall structure and a vehicle using the side wall structure. The vehicle side wall filling module comprises a module body used for being installed in a vehicle side wall frame. The module body is of a sandwich plate structure; the sandwich plate structure comprises supporting structures on the two sides and a core layer arranged inthe supporting structures; the supporting structures on the outer sides of the sandwich plate structure form an outer panel of a vehicle, and a connecting structure used for being connected with a side wall frame is arranged on the sandwich plate structure. Compared with a traditional vehicle panel composed of a steel framework and a metal skin, the weight of a vehicle body is reduced through thesandwich plate structure, and modular production of the vehicle body is conveniently achieved. The sandwich plate structure is connected with the side wall frame through the connecting structure, sothat the connecting process of the sandwich plate structure and the vehicle side wall frame is simple. The problems that in the prior art, a vehicle body is large in weight and complex in working procedure and has many parts and fails to meet the requirements for lightweight and modular production are solved.

Description

technical field [0001] The invention relates to a vehicle side wall loading module, a side wall structure and a vehicle using the side wall structure. Background technique [0002] At present, in order to achieve energy saving and environmental protection of vehicles, lightweight body has become a research hotspot in the field of vehicle manufacturing. The body side wall structure of a traditional bus is mainly a rigid or aluminum frame connected skin structure, such as figure 1 As shown, the traditional passenger car body side wall structure includes side wall columns 10, waist beams 12, and also includes diagonal braces 11 arranged between the passenger car side wall columns. Adding diagonal braces 11 between the passenger car side wall columns can ensure the structure of the bus. Strength, improve the safety performance of the bus, and at the same time, in order to improve the thermal insulation performance of the bus, foam polyurethane material at the side wall. Althou...
