Description

Technical Field

[0001] The present application relates to the field of rail transportation, and in particular to a display device and a rail vehicle. Background Art

[0002] Urban rail transit is currently the preferred mode of transportation for urban commuters. With the rapid development of informatization, electronic display screens have become commonplace in urban rail transit vehicles. To facilitate access to vehicle / train information for passengers on the platform, electronic display screens are typically placed on the side of the vehicle.

[0003] There is a common way to install electronic display screens on the market. Display screen 1 faces the car window glass. The mounting interfaces on both sides of display screen 1 are mounted to the car body vertical beams 4 and reinforcement plates 5 on both sides of the car window through brackets 3. The reinforcement plates 5 are equipped with threads for mounting and fastening the brackets 3. Figure 1 The inner side of the display screen 1 (i.e. the passenger compartment side) should be equipped with a cover plate 2 made of the same material as the internal device, as shown in FIG. Figure 2 As shown, another adapter structure 6 is also designed for installing the cover plate 2.

[0004] This electronic display installation method, limited by the width of the vehicle window and the display, has a limited scope of application and poor scalability. If the width of the window and display do not match, the solution cannot be implemented, or the bracket will be too wide, reducing the window's light transmission area and affecting the passenger experience. Furthermore, the display's mounting structure and the cover's mounting structure are separated, making installation and debugging inconvenient, increasing operator time, and affecting installation efficiency.

[0005] It can be seen from this that when installing an electronic display screen in a vehicle's side window, the design width of the vehicle's side window and the size of the electronic display screen itself should usually be considered. At the same time, the equipment wiring plan and the convenience of daily inspection and maintenance should also be considered. Summary of the Invention

[0006] In order to solve one of the above technical deficiencies, an embodiment of the present application provides a display device and a rail vehicle.

[0007] According to a first aspect of an embodiment of the present application, a display device is provided, comprising a display screen, a cover panel, and a bracket, wherein the display screen and the cover panel are mounted on the bracket, and the front panel of the display screen faces the side window of the vehicle body, the bracket is fixed to the crossbeam above the side window of the vehicle body, and the rear panel of the display screen and the bracket are wrapped by the cover panel.

[0008] According to a second aspect of the embodiments of the present application, a rail vehicle is provided, comprising the display device according to the first aspect of the embodiments of the present application.

[0009] The display device provided in the embodiments of this application integrates the display screen and the cover panel together using a bracket and then mounts it on a beam above the vehicle side window, thereby achieving a suspended display installation method. This makes the display device unaffected by the size of the vehicle side window or the display screen, thus extending its applicability. Furthermore, it occupies less vehicle window area, increasing the light-transmitting area of ​​the vehicle side window and enhancing the passenger experience and comfort.

[0019] In order to make the technical solutions and advantages of the embodiments of the present application more clearly understood, the exemplary embodiments of the present application are further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, and are not an exhaustive list of all the embodiments. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other unless they conflict.

[0020] Example 1

[0021] like Figure 3 As shown, this embodiment provides a display device, which is suitable for use in rail vehicles. The display device includes a display screen 1, a cover panel 2 and a bracket 3. Among them, the bracket 3 can be formed by bending an aluminum alloy plate, and reinforced ribs are welded to meet the high strength requirements of rail vehicles. A mounting interface that cooperates with the display screen 1 and the cover panel 2 is provided on the bracket 3, so that the display screen 1 and the cover panel 2 can be integrated on the bracket 3. Specifically, the display screen 1 is first installed on the bracket 3, and the front panel of the display screen 1, that is, the display panel, faces the side window of the vehicle body. Then the bracket 3 is installed on the crossbeam 10 above the side window of the vehicle body. Finally, the cover panel 2 is wrapped around the rear panel of the display screen 1 and the bracket 3, thereby completing the overall installation of the display device. Of course, the order of the second and third steps can be swapped without affecting the installation of the overall structure.

[0022] Furthermore, in this embodiment, the display screen 1 and the bracket 3 are fixedly connected via mutually cooperating mounting interfaces, and the fixing method can be a bolt connection, such as Figure 3 In order to facilitate the adjustment of the position of the display screen 1, the mounting interface on the bracket 3 can be set to a long strip shape, so that the display screen 1 can be adjusted horizontally to achieve the best position, as shown. Figure 4 At the same time, a shock-absorbing pad 9 is attached to the frame of the front panel of the display screen 1, which can effectively prevent the front panel of the display screen 1 from rubbing and vibrating against each other after being closely attached to the side window of the vehicle body. Figure 3 shown.

[0023] A pressure riveting stud 8 is also provided on the bracket 3 to facilitate single-sided fastening installation. Figure 4 As shown. This self-clinching stud 8 can be used to install accessory structures, such as the wiring harness for display screen 1. Furthermore, this self-clinching stud 8 can also be used to install display screen 1 or cover panel 2. The use of self-clinching studs 8 ensures the mounting strength of each component while reducing installation and maintenance time, eliminating debugging steps, and improving assembly and maintenance efficiency.

[0024] After assembling the bracket 3 and the display screen 1, the bracket 3 is mounted on the crossbeam 10 above the side window of the vehicle body. The bracket 3 and the crossbeam 10 can be connected by bolts, and an anti-rotation nut 11 is provided on the bolt, so that the bolt can be tightened directly on one side in the vehicle body without using other tools to lock the nut. Figure 5 shown.

[0025] After the bracket 3 and the crossbeam 10 are installed, the cover plate 2 is installed on the bracket 3. A hinge 12 is provided at the bottom of the cover plate 2. Figure 5 and Figure 6As shown, the hinge 12 can be fixedly connected to the bracket 3 via a mounting interface, allowing the cover panel 2 to be opened and closed via the hinge 12, facilitating maintenance of the display screen 1. The cover panel 2 and bracket 3 are also provided with cooperating locking members 13, which can be connected by a snap-fit ​​connection, ensuring the stability of the cover panel 2 on the bracket 3 and facilitating its opening and closing. Furthermore, the cover panel 2 is provided with a safety rope 14, which can be tied into a pre-recorded hole in the bracket 3 to ensure further stability of the cover panel 2.
