Description

Technical Field

[0001] The present invention relates to the technical field of vehicle body structures, and in particular to a low-floor tram carriage and a vehicle. Background Art

[0002] The floor of a low-floor tram is only 35 cm above the track surface, and there is no need for a platform. It has a large passenger carrying capacity and can be laid on existing roads in the city. It is low-cost, energy-saving, environmentally friendly, and low-noise. It is one of the most advanced urban transportation systems in the world today. In recent years, low-floor trams have developed rapidly as a new type of transportation equipment in modern cities and have been widely promoted in emerging cities, branch lines of large cities, and small and medium-sized cities in my country.

[0003] Compared with subway vehicles, low-floor vehicles have a lower floor height, and the bogies are placed inside the vehicle body. The vehicle body is equipped with a wheel box cover to separate the bogies from the interior of the passenger compartment. When viewed from the passenger compartment, the wheel box cover protrudes from the passenger compartment floor surface. The vehicle body structure is as follows: Figure 1 As shown. Therefore, when doing interior design, it is necessary to design a separate wheel box cover to cover the wheel box cover of the vehicle body. In terms of installation, the interior side wall panel is installed first, and the wheel box cover is installed later, and the wheel box cover presses the interior side wall panel. If the side wall panel is damaged for some reason and needs to be replaced, the wheel box cover must be removed first. The wheel box cover is attached to the vehicle body wheel box cover on three sides, and it is not easy to install and remove. In addition, the wheel box cover is installed with seats, handrails and other equipment, and there are skeletons, sand spreading devices, wheel rim lubrication and other equipment inside, so the disassembly workload is huge. Therefore, the problem of replacing damaged side wall panels is a difficult point in the interior design of low-floor vehicles.

[0004] Prior art 1: The problem of separate disassembly and assembly of the interior side wall panels on low-floor vehicles has always been a difficult problem. The structures currently used are as follows: Figure 2 As shown, there are 4 (or similar) interior wall panels on one side of the vehicle, and each window is a whole large wall panel.

[0005] Prior art 2: This technical solution takes into account the problem of disassembly and assembly of the side wall panels at the wheel box cover of the vehicle. The interior side wall panels on one side of the vehicle are arranged into 8 pieces, and the side wall panels in the wheel box cover area are split.

[0006] But the shortcomings of prior art one are as follows:

[0007] In this technical solution, only the wall panels shown by item number 1 and item number 3 can be disassembled separately.

[0008] The side wall panels shown by part numbers 2 and 4 cannot be removed separately because they are pressed and blocked by the wheel box cover and the seats. If these two side wall panels are removed, the eight seats, two wheel box covers and their attached connectors, the internal frame, the sand spreading device, the wheel rim lubrication device, etc. must be removed in turn. The workload is huge and the operation is difficult, which is not conducive to vehicle maintenance.

[0009] The disadvantages of the prior art 2 are as follows:

[0010] This technical solution splits the side wall panels of the wheel box cover and the seat area, allowing the wall panels to be removed individually. However, there are a large number of side wall seams, and most of them are located in obvious positions inside the passenger compartment, which has a significant impact on the aesthetics of the vehicle.

[0011] The side wall structure of this technical solution is not easy to adjust the gap evenly during installation, which makes installation difficult, and the uneven gap adjustment seriously affects the aesthetics of the vehicle.

[0012] The side wall panels shown by item numbers 7 and 8 are affected by the wheel box cover and the seat. Although they can be disassembled and assembled, the operation is difficult, which is not conducive to the operation and maintenance of the vehicle. Summary of the invention

[0013] The technical problem to be solved by the present invention is to provide a split interior side wall panel structure designed to address the disadvantage that the existing interior side wall panels cannot be disassembled separately while taking into account aesthetics, and fully consider the convenience of disassembly and assembly, so as to provide a low-floor tram with a detachable interior side wall and a vehicle that can quickly realize the disassembly and assembly of the side wall.

[0014] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0015] A low-floor tram carriage comprises a car body and a side wall assembly, wherein the car body comprises an inner side wall and a car body wheel box cover arranged in the car body, and the car body wheel box cover has a seat placement position;

[0016] The side wall assembly includes an upper wall plate, a connecting plate, and a lower wall plate. The upper wall plate is provided with a notch at a position relative to the seat placement position and is connected to the vehicle body.

[0017] The connecting plate matches the shape of the notch and is detachably connected to the upper wall plate and the wheel box cover of the vehicle body;

[0018] The lower wall panel is arranged on the side wall below the upper wall panel and the lower edge of the lower wall panel matches the edge shape of the wheel box cover of the vehicle body; if the wheel box cover of the vehicle body divides the side wall below the upper wall panel into multiple areas, then the lower wall panel has multiple pieces and is arranged corresponding to the multiple areas.

[0019] In order to solve the above technical problems, another technical solution adopted by the present invention is:

[0020] A vehicle comprises a plurality of the above-mentioned low-floor tram carriages.

[0021] The beneficial effects of the present invention are as follows: the detachable side wall structure of the present invention, i.e., the door cover and the side wall assembly, can realize the independent removal and replacement of the side wall panel without removing other components when the side wall is damaged, thereby saving time and labor, being beneficial to the operation and maintenance of the vehicle, and the added side wall seams are fewer and more concealed, which has little effect on the aesthetics of the vehicle interior; and the detachable side wall assembly has a simple structure and almost no increase in production cost.
