Problems solved by technology

In order to ensure the force and load of the whole vehicle, the opening area of ​​the window is limited to a small range, and the side wall panels of sufficient width must be ensured at the side of the door and the window, which will lead to insufficient light in the compartment and also affect the appearance of the vehicle
In addition, the manufacturing process of this car body side wall is also relatively complicated.

Embodiment Construction

[0011] The present invention will be further described in detail below with reference to the accompanying drawings and examples. However, the invention is not limited to the examples given.

[0012] Such as figure 2 As shown, the side wall of the subway vehicle of the present invention includes upper side beam 1, lower side beam 7 and vehicle window 4, and is characterized in that: there are profile columns 5 distributed at intervals with the width of the opening of the vehicle door and vehicle window, and the upper and lower sides of the profile column 5 are The lower ends are welded together with the upper side sill 1 and the lower side sill 7 respectively, and the window area between the adjacent profile columns has a window upper plate 8 and a window lower plate 9 riveted and fixed with the upper side sill 1 and the lower side sill 7 respectively, and the window 4 glass It is located between the upper window plate 8 and the lower window plate 9.

Abstract

The side wall for underground vehicle consists of upper edge beam, lower edge beam and window, and has spaced uprights of sections with upper end and lower end welded separately to the upper edge beam and the lower edge beam, upper window plates, lower window plates and glass windows mounted onto the upper window plates and the lower window plates. Unlike available technology, which has bearing side wall plates, the present invention has bearing uprights, capacity of increasing window area, improved look and other advantages.

Description

technical field [0001] The invention relates to a car body side wall of a subway vehicle, in particular to a novel side wall structure of a subway vehicle. Background technique [0002] At present, the aluminum alloy subway vehicles currently in use in China have side wall structures such as figure 1 As shown, it is to weld a plurality of aluminum alloy hollow profiles 3 into a side wall panel, and then combine with side wall side beams 1, side wall lower side beams 7 and columns 2 and cross beams (in the figure) for strengthening the strength of car doors and windows. Not shown) the whole group is welded into a side wall structure. figure 1 10 indicates the door area. In this type of side wall structure, the vertical load on the upper part of the car body is mainly transmitted downward through the side wall panels, while the doors and windows are formed through openings on the side wall panels. In order to ensure the force and load of the whole vehicle, the opening area ...
