Description

Technical Field

[0001] This application relates to the field of rail transit technology, and in particular to a side door and rail train equipped with an external display. Background Technology

[0002] Currently, exterior information displays on rail trains are generally located on the side walls of the train body near the side doors, allowing passengers boarding and alighting to observe vehicle information. To install these displays, a separate opening needs to be made in the side wall near the side doors, and the display window is installed at this opening.

[0003] However, for high-speed trains, when vehicles pass each other at high speeds, extremely large aerodynamic pressure waves are generated in the sidewall area. This necessitates further enhancing the load-bearing strength of components such as the train body, doors, and windows compared to existing high-speed trains. Therefore, if external information displays are installed through separate openings in the sidewalls of the car body using traditional methods, it would create additional openings, leading to a reduction in the load-bearing strength of the car body and failing to meet the requirements for safe vehicle operation.

[0004] Given the above problems, how to solve the problem of the impact of the current installation of external displays on the side walls of the vehicle body on the load-bearing strength of the vehicle body is an urgent problem for technicians in this field to solve. Summary of the Invention

Detailed Implementation

[0027] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0028] The core of this application is to provide a side door and rail train equipped with an external display, in order to solve the problem that the installation of the external display on the side wall of the vehicle body affects the load-bearing strength of the vehicle body.

[0029] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Currently, when high-speed trains pass each other at high speed, their sidewall areas generate extremely large aerodynamic pressure waves. Therefore, it is necessary to further enhance the load-bearing strength of components such as the train body, doors, and windows, based on existing high-speed train sets, to meet the requirements for safe operation. There are several ways to improve the load-bearing strength of the car body. Among them, simplifying car body openings can reduce damage to the overall structure of the car body, and integrating equipment that requires car body openings into a single design can reduce the number of openings, which is one of the effective means to improve the load-bearing strength of the vehicle.

[0031] Currently, exterior information displays on rail trains are generally located on the side walls of the train body near the side doors, allowing passengers boarding and alighting to observe vehicle information. Specifically, each side door has a separate opening on the side wall for installing the exterior display window. However, this design adds extra openings to the train body, reducing its load-bearing capacity.

[0032] In view of the above problems, this application provides a side door equipped with an external display to solve the problem that the current installation of external displays on the side wall of the vehicle body affects the load-bearing strength of the vehicle body.

[0033] Figure 1 This is a schematic diagram of a side door equipped with an external vehicle display, provided as an embodiment of this application. Figure 1 As shown, the side door includes an exterior display 10 and a display window 11; wherein, the side door is provided with a window frame opening corresponding to the display window 11, and the display window 11 and the exterior display 10 are an integral structure;

[0034] The display window 11 is fixed to the window frame opening. The outer surface of the display window 11 coincides with the outer surface of the side door, and the inner surface of the display window 11 faces the display area of ​​the external display 10.

[0035] The exterior display 10 is fixed to the interior space of the side door corresponding to the window frame opening, and the display area of ​​the exterior display 10 faces the outside of the side door through the display window 11.

[0036] Specifically, to enable the installation of the exterior display 10 on the side door, a window frame opening corresponding to the display window 11 needs to be provided on the side door. It is important to note that the shape and size of the window frame opening should perfectly correspond to the display window 11. For example, when the display window 11 is circular, the shape of the window frame opening should also be circular; when the display window 11 is rectangular, the shape of the window frame opening should also be rectangular, thus ensuring that the display window 11 can be completely fixed to the window frame opening. Simultaneously, the outer surface of the display window 11 coincides with the outer surface of the side door, making the display window 11 and the side door a unified whole, resulting in a more harmonious appearance. In this embodiment, the specific location of the window frame opening on the side door is not limited and depends on the specific implementation.

[0037] Furthermore, the display window 11 and the exterior display 10 are an integral structure, and they can be connected by adhesive bonding or other methods, depending on the specific implementation. To facilitate heat dissipation of the exterior display 10, a spacer cavity can be provided between the display window 11 and the exterior display 10 for heat dissipation.

[0038] The exterior display 10 is fixed in the interior space of the side door corresponding to the window frame opening, that is, the thickness of the side door is used to accommodate the exterior display 10; at the same time, the display area of ​​the exterior display 10 faces the outside of the side door through the display window 11. The display window 11 should be made of a light-transmitting material, such as light-transmitting glass, so that the display content of the exterior display 10 can be displayed to the outside through the display window 11.

[0039] It should be noted that this embodiment does not limit the specific method of fixing the display window 11. It can be fixed by adhesive to the window frame opening of the side door, or by other methods, depending on the specific implementation. Similarly, this embodiment does not limit the specific method of fixing the exterior display 10. It can be fixed by adhesive to the interior space of the side door, or by fixing screws, depending on the specific implementation.

[0040] In this embodiment, the side door equipped with the external display includes the external display and a display window. The side door has a window frame opening corresponding to the display window, and the display window and the external display are an integral structure. The display window is fixed to the window frame opening, with its outer surface coinciding with the outer surface of the side door, and its inner surface facing the display area of ​​the external display. The external display is fixed within the interior space of the side door corresponding to the window frame opening, and its display area faces the outside of the side door through the display window. Therefore, the above solution, by installing the external display on the vehicle's side door, not only meets the user's need to obtain vehicle information but also eliminates the need for additional installation openings on the vehicle's side wall, preventing the installation of the external display from affecting the vehicle's load-bearing capacity and ensuring the vehicle's safe operation.

[0041] In order to cover the internal structure of the side door at the window frame opening, based on the above embodiments, in some embodiments, the transparent area of ​​the display window 11 is larger than the display area of ​​the external display 10; the portion of the transparent area of ​​the display window 11 that is larger than the display area of ​​the external display 10 is provided with black silkscreen.

[0042] Specifically, when setting up the display window 11, the transparent area of ​​the display window 11 is set to be larger than the display area of ​​the external display 10 to ensure that the external display 10 can display completely to the outside. Furthermore, in order to cover the internal structure of the side door at the window frame opening, the portion of the transparent area of ​​the display window 11 that is larger than the display area of ​​the external display 10 is marked with black silkscreen. This achieves a more aesthetically pleasing installation effect while ensuring the complete display of the external display 10 and covering the internal structure of the window frame opening.

[0043] In order to better secure the exterior display 10, based on the above embodiments, as a preferred embodiment, the side door further includes: an L-shaped fixing structure 12;

[0044] The L-shaped fixing structure 12 is fixed to the hollow profile structure 13 of the window frame opening section by screws 18, so as to fix the exterior display 10 to the L-shaped fixing structure 12 by screws 18.

[0045] Specifically, an L-shaped fixing structure 12 is provided at the cross-section of the window frame opening of the side door. The L-shaped fixing structure 12 is then fixed to the hollow profile structure 13 at the window frame opening cross-section using screws 18. It is understood that the hollow profile structure 13 is part of the side door, and its function is for fixing the screws 18. This embodiment does not impose limitations on its specific construction; it depends on the specific implementation.

[0046] After fixing the L-shaped fixing structure 12 to the window frame opening with screws 18, the exterior display 10 is further fixed to the L-shaped fixing structure 12 with screws 18, thereby achieving a more stable installation of the exterior display 10.

[0047] Based on the above embodiments, in some embodiments, a sealant 14 is provided between the display window 11 and the hollow profile structure 13 to fill the gap between the display window 11 and the window frame opening.

[0048] Understandably, since high-speed trains typically operate in high-speed environments, in order to ensure the airtightness of high-speed trains, in specific implementations, sealant 14 is installed between the display window 11 and the hollow profile structure 13 of the side door. The sealant 14 fills the gap between the display window 11 and the window frame opening, thus ensuring the airtightness of the high-speed train.

[0049] Based on the above embodiments, in some embodiments, the hollow profile structure 13 is provided with a wiring port 15 for connecting the cable of the external display 10 to the vehicle controller through the wiring port 15.

[0050] In order to control the information displayed on the exterior display 10, a wiring port 15 is provided on the hollow profile structure 13 of the side door in a specific implementation. The wiring port 15 allows the cable of the exterior display 10 to pass through, so that the cable of the exterior display 10 can be connected to the vehicle controller through the wiring port 15, so that the vehicle controller can control the display content of the exterior display 10.

[0051] It should be noted that in this embodiment, there are no restrictions on the location and number of wiring ports 15. It is only necessary to ensure that the cable of the external display 10 can be connected to the vehicle controller through the wiring port 15, depending on the specific implementation.

[0052] In order to enable maintenance of the exterior display 10, in some embodiments, based on the above embodiments, the side door further includes: a maintenance cover 16;

[0053] The access cover 16 is fixed to the window frame opening, and the outer surface of the access cover 16 coincides with the inner surface of the side door.

[0054] Specifically, the exterior display 10 is located inside the side door corresponding to the window frame opening. The display area of ​​the exterior display 10 faces the outside of the side door through the display window 11, while the main structure of the exterior display 10 is exposed on the inside of the side door. To cover the exposed structure of the exterior display 10 on the inside of the side door and facilitate maintenance and repair, in this implementation, a maintenance cover 16 is fixed to the window frame opening, with its outer surface overlapping the inner surface of the side door. This completely covers the main structure of the exterior display 10 and forms a single plane with the inside of the side door, ensuring the aesthetics of the inside of the side door. It should be noted that this embodiment does not limit the specific fixing method of the maintenance cover 16; it can be fixed by adhesive or screws, depending on the specific implementation.

[0055] In a preferred embodiment, the inspection cover 16 is fixed to the hollow profile structure 13 by screws 18. The number of screws 18 is not limited in this embodiment; it is sufficient to ensure that the inspection cover 16 is completely fixed to the hollow profile structure 13, depending on the specific implementation.

[0056] Based on the above embodiments, in order to improve the sound insulation performance of the side door, in some embodiments, the side door further includes: sound insulation felt 17;

[0057] The sound insulation felt 17 is placed in the interior space of the side door corresponding to the window frame opening and is adhered to the inner surface of the inspection cover plate 16.

[0058] Because a window frame opening is provided on the side door to install the external display 10 and the display window 11, the sound insulation performance of the side door is reduced. In order to prevent external noise generated during high-speed train operation from entering the carriage through the side door, in this embodiment, sound insulation felt 17 is placed in the internal space of the side door corresponding to the window frame opening and is adhered to the inner surface of the inspection cover 16.

[0059] It is understood that in this embodiment, the sound insulation felt 17 is placed between the inspection cover 16 and the external display 10, effectively reducing noise transmission and ensuring the sound insulation performance of the side door. It should be noted that this embodiment does not limit the size and shape of the sound insulation felt 17; it depends on the specific implementation. To ensure sound insulation quality, in specific implementations, the size and shape of the sound insulation felt 17 can be set to perfectly correspond to the window frame opening, thereby maximizing the absorption of noise transmitted through the window frame opening.

[0060] Figure 2This is a schematic diagram of another side door equipped with an external display, provided as an embodiment of this application. Based on the above embodiments, in some embodiments, such as... Figure 2 As shown, the window frame opening is located above the door core window 19 of the side door and is within the user's direct line of sight.

[0061] To ensure that users can more conveniently and intuitively view the information displayed on the exterior display 10, the window frame opening is specifically positioned above the door core window 19 of the side door, and within the user's direct line of sight. This reasonable height setting of the exterior display 10 makes it easier for passengers to observe train number, destination, and other vehicle information, thus improving the passenger experience.

[0062] Furthermore, this application also provides a rail train, including the side door with an external display as described in the above embodiments. The rail train can achieve all the functions and effects of the side door with the external display during operation. Specifically, the side door with the external display includes an external display and a display window; wherein, the side door has a window frame opening corresponding to the display window, and the display window and the external display are an integral structure; the display window is fixed to the window frame opening, the outer surface of the display window coincides with the outer surface of the side door, and the inner surface of the display window faces the display area of ​​the external display; the external display is fixed in the internal space of the side door corresponding to the window frame opening, and the display area of ​​the external display faces the outside of the side door through the display window. Therefore, the above solution, by installing the external display on the vehicle side door, not only meets the user's need to obtain vehicle information, but also eliminates the need to add installation openings to the side wall of the vehicle body, avoiding any impact on the load-bearing strength of the vehicle body from the installation of the external display, and ensuring the safe operation requirements of the vehicle.
