Description

Technical Field

[0001] This utility model relates to the field of vehicle structure, and in particular to a vehicle compartment end wall structure. Background Technology

[0002] The end walls of train carriages, light rail, and subway vehicles, which are the walls at both ends of the carriage with a passageway in between, are mainly composed of stainless steel frames and stainless steel plates. These materials and structures are heavy, difficult to process, and inconvenient to install, resulting in heavy carriages and high energy consumption during vehicle operation. Summary of the Invention

[0003] In view of this, it is necessary to provide a carriage end wall structure that is simple in structure, easy to manufacture, easy to assemble, and has a small self-weight.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a carriage end wall structure, comprising:

[0005] The frame is made of hard metal, and has a pedestrian passage in the middle. Mounting frames are provided on the left, right and top sides of the pedestrian passage.

[0006] The wall panel is equal in number to the number of mounting frames. The wall panel is fixedly connected within the mounting frame and its dimensions are adapted to those of the mounting frame. The wall panel includes a foamed material interlayer and a panel fixedly connected to the front and back surfaces of the interlayer. The panel is made of basalt.

[0007] Furthermore, it also includes a fixing groove made of hard metal, which covers the peripheral sidewall of the wall panel.

[0008] Furthermore, decorative panels are fixedly connected to the front and rear surfaces of the frame, and the decorative panels have through holes adapted to the pedestrian passage.

[0009] Furthermore, the fixing groove forms a fixing frame surrounding the periphery of the wall panel, and the front or rear side of the fixing frame has a plurality of reinforcing ribs connecting the upper and lower ends of the fixing frame.

[0010] Furthermore, the interlayer is a PPO board foamed and molded within the fixing groove and the panel.

[0011] Furthermore, baffles are fixedly connected to the front and rear sides of the mounting frames located on the left and right sides of the pedestrian passage to prevent the wall panels from detaching.

[0012] Furthermore, a plurality of connectors are fixedly connected to the frame around the pedestrian walkway, and the connectors have mounting holes.

[0013] Furthermore, the panel is a basalt slab.

[0014] Furthermore, the frame and the fixing groove are made of stainless steel or aluminum alloy.

[0015] Compared with the prior art, the present invention has the following advantages: the device removes most of the stainless steel components of the original carriage end wall and replaces them with PPO plates and basalt plates, which effectively reduces the weight of the end wall. The structure is simple, the manufacturing is fast, and the assembly is convenient.

[0016] To make the above and other objects, features and advantages of this utility model more apparent and understandable, preferred embodiments are described below in detail with reference to the accompanying drawings. Attached Figure Description

[0023] To further illustrate the technical means and effects of this utility model in achieving its intended purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0024] like Figure 1-5 As shown, a carriage end wall structure includes: a frame 1, a wall panel 3, and a decorative panel 2.

[0025] The frame 1 is made of stainless steel. The frame 1 has a pedestrian passage 11 in the middle. The frame 1 is equipped with a mounting frame 12 on the left, right and top sides of the pedestrian passage 11.

[0026] There are three wall panels 3. The wall panels 3 are fixedly connected inside the mounting frame 12, and the wall panels 3 are adapted to the size of the mounting frame 12.

[0027] The wall panel 3 includes a fixing groove 33, a sandwich layer 31, and a panel 32. The fixing groove 33 is made of stainless steel, the sandwich layer 31 is made of PPO sheet, and the panel 32 is made of basalt sheet. The panel 32 is bonded to the front and back surfaces of the sandwich layer 31, and the fixing groove 33 forms a fixing frame surrounding the perimeter of the wall panel. When manufacturing the wall panel 3, the fixing grooves 33 on the other sides of the wall panel 3 are first welded into shape, leaving one fixing groove 33 unused. Then, the panel 32 is placed on both sides of the welded fixing groove 33. PPO is injected into the fixing groove and the panel, causing it to foam and form a PPO sheet within the cavity formed by the fixing groove 33 and the panel 32, thus forming the sandwich layer 31. Finally, the last fixing groove is welded onto it to form a one-piece molded wall panel 3.

[0028] To improve the strength of the fixing frame, the front or rear side of the fixing frame has multiple reinforcing ribs 34 that connect the upper and lower ends of the fixing frame.

[0029] Decorative panels 2 are fixedly connected to the front and rear surfaces of the frame 1 respectively, and decorative panels 2 have through holes adapted to the pedestrian passage 11.

[0030] In this embodiment, baffles 13, which prevent the wall panels from detaching, are fixedly connected to the front and rear sides of the mounting frames located on the left and right sides of the pedestrian passage 11.

[0031] In this embodiment, multiple connectors 14 are fixedly connected to the frame around the pedestrian walkway 11, and each connector 14 has a mounting hole 15.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
