A modular interior side wall panel structure for a railway passenger car

Abstract

The railway passenger car modular interior side wall panel structure of the present invention includes the wall panel fixed on the frame and the cold-proof material arranged on the outside of the wall panel, the outer side of the frame is fixed with connecting iron, and the frame, wall panel, cold-proof material and connecting iron form an integrated structure For the wall panel module, the inner side of the side wall longitudinal beam of the vehicle is provided with connecting angle irons, and the connecting irons between adjacent integrated wall panel modules are arranged in a staggered manner and fixed with the connecting angle irons; the adjacent sides of adjacent wall panels are concave , and a cover strip covering the gap between the two is provided; the outer side of the wall panel of the integrated wall panel module near the vehicle end is inserted into the decorative cover strip fixed on the partition wall. The design concept of the modular interior side wall panel of the present invention is to assemble the side wall panel, frame, connecting iron and cold-proof material together to form an integrated wall panel module. The connecting iron on the frame is arranged toward the outside of the frame and the adjacent frame The staggered layout of the connecting irons obviously satisfies the installation mode of the wall panel module integrated assembly on the vehicle, and improves the assembly manufacturability.

Description

technical field [0001] The invention relates to a breakthrough innovative design for the semi-modular design structure and installation method of the existing 25T type hard seat car interior side wall panel, and belongs to the technical field of the 25T type hard seat car side wall interior structure system. At the same time, this technology is also applicable to the modification of the modular design of the interior side wall panels of the 25T hard seat car factory in the off-stage period and the improvement design of the interior side wall panels of the new 25T hard seat car designed and produced later. The application and implementation of this technology will greatly improve the production and assembly efficiency of 25T rigid seat vehicles. Background technique [0002] 25T bus has become a mature bus product of various vehicle manufacturers, and the degree of modularization of the major systems of each model is gradually improving.

Problems solved by technology

[0002] 25T bus has become a mature bus product of various vehicle manufacturers, and the degree of modularization of the major systems of each model is gradually improving. Wall panels and aluminum frames are assembled separately on the vehicle, which has always been a shortcoming that restricts the assembly time and installation quality of wall panels.
