Description

Technical Field

[0001] This utility model relates to the field of rail vehicle technology, and in particular to a side wall module installation structure and a rail vehicle. Background Technology

[0002] As people's living standards improve, passengers have increasingly higher requirements for the interior environment of rail vehicles. As the primary interface for human-machine interaction within the rail vehicle passenger compartment, the interior system directly impacts the overall effect. Interior installation must not only meet safety and workmanship requirements but also comfort and aesthetics. The installation effect of the side wall modules directly determines the installation of the side roof panels, while the installation structure of the vertical cover panels and side wall panels plays a decisive role in the installation effect of the side wall modules.

[0003] In rail vehicles, due to tolerances in the openings of the car body and windows, as well as the tolerances of the interior materials themselves, the gaps between the vertical cover panels and side wall panels after installation are not entirely the same. There are also tolerances in the spacing of the vertical cover panels at each doorway. This results in misalignment between the side top panels of some door areas and the vertical cover panels on both sides. The gaps between the side top panels of the door area and the adjacent side top panels, as well as the gaps between the side wall panels and the vertical cover panels on the same side, are not straight and aesthetically pleasing. It is difficult to adjust the gaps between the side top panels to be consistent. Under such circumstances, it is difficult to install and adjust the side top panels. It is necessary to cut the side top panels according to different situations or customize side top panels of specific lengths. This not only greatly reduces production efficiency but also seriously affects the overall installation effect of the interior. Utility Model Content

[0031] The purpose of this utility model is to provide a side wall module installation structure and a rail vehicle. The upright cover and the side wall panel are connected by a plug-in structure. The plug-in amount can be adjusted, and there is no need to cut the first and second side top panels or customize the first and second side top panels to a specific length. This improves production efficiency and avoids the problem of uneven and unsightly gaps between the first and second side top panels and between the upright cover and the side wall panel on the same side. This solves the problems existing in the prior art.

[0032] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the following description is provided in conjunction with the appendix. Figures 1-9 The present invention will be further described in detail below with reference to specific embodiments.

[0033] Example 1

[0034] This embodiment provides a sidewall module installation structure 100, for reference... Figure 1 , 2 8, 9, including a vertical cover plate 1, a side wall plate 2, and a plug-in structure 3. The vertical cover plate 1 is used to be installed on both sides of the inner side of the door, and a first side top plate 5 is used to be installed on the upper part of the vertical cover plate 1. The side wall plate 2 is used to be installed on the inner side of the window area. The side wall plate 2 is connected to the side wall of the vehicle body through an adjustable connecting structure 4 so that the installation position of the side wall plate 2 can be adjusted along the length direction of the vehicle body. The second side top plate 6 is used to be installed on the upper part of the side wall plate 2. The plug-in direction of the plug-in structure 3 is arranged along the length direction of the vehicle body. The vertical cover plate 1 and the side wall plate 2 are connected through the plug-in structure 3, and the plug-in amount of the plug-in structure 3 can be adjusted. The side wall module mounting structure 100 provided in this embodiment connects the upright cover plate 1 and the side wall plate 2 via a plug-in structure 3, and connects the side wall plate 2 to the vehicle body side wall via an adjustable connection structure 4. The plug-in depth of the plug-in structure 3 can be adjusted by adjusting the installation position of the side wall plate 2. This eliminates the need for cutting the first side top plate 5 and the second side top plate 6 or customizing the first side top plate 5 and the second side top plate 6 to specific lengths, improving production efficiency. Furthermore, the plug-in depth of the upright cover plate 1 and the side wall plate 2 can be adjusted, thereby reducing the impact of machining tolerances and installation tolerances of the upright cover plate 1 and the side wall plate 2 on the installation gaps. This avoids the problem of uneven and unsightly gaps between the first side top plate 5 and the second side top plate 6 and the gaps between the upright cover plate 1 and the side wall plate 2 on the same side. (Reference) Figure 8 This is an installation diagram showing the gaps between the first and second side top panels 5 and the vertical cover panel 1 and the side wall panel 2 after installation using traditional methods.
