Description

Technical Field

[0001] This utility model belongs to the field of rail vehicle technology, specifically relating to an integrated structure for the roof ventilation duct of a rail vehicle. Background Technology

[0002] Traditional rail transit vehicle roof systems consist of a car body roof, air ducts, air grilles, and interior trim panels. For double-decker EMUs, the upper level is generally smaller than the lower level, creating a need to increase the net standing space for passengers. Therefore, it is crucial to minimize the height occupied by the car body roof, air ducts, and interior trim panels. How to rationally design the roof structure to ensure that, within a limited space, the functions of structures such as air ducts are achieved while reducing the space ratio of each component is a challenging problem for R&D designers. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide an integrated structure for the roof ventilation duct of a rail vehicle, which, while realizing the function of air supply, also reduces the proportion of the integrated structure in the car space, so that the rail vehicle has a larger internal net space.

[0004] This utility model discloses an integrated structure for a roof-mounted air duct of a rail vehicle, which is located below the roof of the vehicle body and includes a top plate assembly and two sets of side plate assemblies:

[0005] Both the top plate assembly and the side plate assembly are arranged along the X direction;

[0006] The side panel assemblies are symmetrically arranged on both sides of the top panel assembly;

[0007] The roof panel assembly has a U-shaped cross section along the Y direction. The roof panel assembly and the vehicle body roof together form a first air duct, which is matched and connected to the air conditioning vent.

[0008] The side panel assembly, the roof cover, and the side wall of the roof panel assembly together form a second air duct;

[0009] The side wall is provided with several first air vents that connect the first air duct and the second air duct;

[0010] The top plate assembly and the side plate assembly are provided with a number of second air vents.

[0011] In the aforementioned integrated structure of the roof air duct of the rail vehicle, the top plate component and the side plate component not only serve as interior decorative panels, but also combine with the roof of the car body to form the first air duct and the second air duct for air conditioning, respectively. This eliminates the need for separate air ducts inside the car, saving upper space.

[0012] Furthermore, the second air vent includes an air outlet and / or an air outlet grille.

[0013] Depending on the required air volume, air outlets or air grilles can be installed on the top panel assembly and side panel assembly, and the two can be used in combination.

[0014] Furthermore, the top plate assembly includes several top plates, which are connected sequentially along the X direction.

[0015] Furthermore, several reinforcing ribs are provided on the side of the top plate along the Z direction; the reinforcing ribs are arranged parallel to each other along the X direction; and several third air vents are opened on the reinforcing ribs along the X direction.

[0016] Furthermore, the side panel assembly includes several side panels, which are connected sequentially along the X direction.

[0017] Furthermore, the side panel assembly includes a sealing plate, which is disposed at both ends of the second air duct and matches and corresponds to the second air duct. The sealing plate is provided with a fourth air outlet, which is connected to the air conditioner outlet.

[0018] Furthermore, the sealing plate is also provided with a first opening.

[0019] Furthermore, the side panel assembly is also provided with a second port.

[0020] Furthermore, an insulation layer is also laid on the lower side of the vehicle body roof.

[0021] Furthermore, the integrated structure for the roof ventilation duct of the rail vehicle provided by this utility model also includes a sealing element, which is disposed along the X direction between the side plate assembly and the vehicle body roof.

[0022] This utility model has the following beneficial effects:

[0023] 1) The integrated air duct structure for the roof of the rail vehicle provided by this utility model utilizes the top plate assembly and side plate assembly, which are used as internal decorative panels, to form a first air duct and a second air duct for air conditioning supply when enclosed with the roof of the car body. This simplifies the air duct structure. The air supplied by the air conditioner enters along the first air duct and is then dispersed in the first and second air ducts and evenly delivered to all parts of the car. There is no need to set up separate air ducts. This saves upper space, provides more passenger space, reduces costs, and reduces assembly processes.

[0024] 2) The integrated air duct structure on the roof of the rail vehicle provided by this utility model has air inlets at both ends of the second air duct that are connected to the air conditioning outlets, so that the air conditioning outlets can enter the first and second air ducts at the same time, and the air supply is more uniform.

[0025] 3) A first opening is provided on the sealing plate at the end of the second air duct to form a passage in the second air duct. This passage can be used for the passage of the carriage facilities without the need for additional wiring conduits, which enhances component integration and further reduces the space occupied by the components.

[0026] 4) The insulation layer of the carriage is set on the lower side of the car body roof in the first and second air ducts to reduce the heat transfer from the external environment to the top of the carriage, while enhancing the insulation function of the first and second air ducts.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0043] like Figure 1 , Figure 2 and Figure 5As shown, this utility model provides an integrated structure for a roof-mounted air duct of a rail vehicle, located below the roof cover 001 of the vehicle body. It includes a roof panel assembly 100 and two sets of side panel assemblies 200. Both the roof panel assembly 100 and the side panel assemblies 200 are positioned below the roof cover 001 along the X-direction. The roof panel assembly 100 has a U-shaped cross-section along the Y-direction. The roof panel assembly 100 and the roof cover 001 together form a first air duct 010, which is connected to an air conditioning outlet 002. The side panel assemblies 200... The components are symmetrically arranged on both sides of the roof assembly 100; the side panel assembly 200, the vehicle roof 001, and the side wall 120 of the roof assembly 100 together form the second air duct 020; several first air vents 121 are opened on the side wall 120 to connect the first air duct 010 and the second air duct 020; several second air vents 030 are arranged on the roof assembly 100 and the side panel assembly 200. The above scheme simplifies the air duct structure, provides more seating space, and has the advantage of uniform air supply. The roof panel assembly 100 includes several roof panels 110 connected sequentially along the X direction; the side panel assembly 200 includes several side panels 210 connected sequentially along the X direction. The lengths of the roof panels 110 and side panels 210 along the X direction are selected according to the length of the vehicle, and an appropriate number of roof panels 110 and side panels 210 are set to form a roof panel assembly 100 and a side panel assembly 200 suitable for the vehicle length. The second air vents 030 arranged on the roof panels 110 and side panels 210 are set as evenly arranged air outlets, spaced air outlet grilles, or a combination of both. The air outlets and air outlet grilles can be selected and combined according to the different required air volume. For example, small but dense air outlets are set on the side panel assembly 200 near the seat, and large air volume, spaced air outlet grilles are set on the roof panel assembly 100 corresponding to the aisle to create a comfortable air supply mode.

[0044] The top plate assembly 100 and side plate assembly 200 in the integrated roof air duct structure of the rail vehicle provided by this utility model, while serving as interior decorative panels, also combine with the car body roof 001 to form a first air duct 010 and a second air duct 020 for air conditioning supply, respectively. Figure 5 As shown by the green arrow, the air delivered by the air conditioner enters through the first air duct 010 and then enters the second air duct through the first air outlet 121 provided on the side wall 120 of the top panel assembly 100. The air is dispersed to form a main airflow in the X direction and a lateral airflow in the Y direction. This causes the air delivered by the air conditioner to form turbulence and diffuse in the connected first air duct 010 and second air duct 020. After the airflow is dispersed in the first air duct 010 and second air duct 020, it is delivered to various parts of the vehicle interior through the second air outlet 030 on the top panel assembly 100 and the side panel assembly 200. There is no need to set up a separate air duct, which saves upper space, reduces costs, and reduces assembly processes.

[0045] like Figure 5 , Figure 7As shown, in some embodiments provided by this utility model, a number of reinforcing ribs 130 are provided on the upper side of the top plate 110 along the Z direction to increase the structural strength of the top plate 110; the reinforcing ribs 130 are arranged parallel along the X direction; a number of third air vents 131 are opened on the reinforcing ribs 130 along the X direction to ensure the gas flow of the first air duct 010.

[0046] like Figure 3 , Figure 4 as well as Figure 6 As shown, in some embodiments provided by this utility model, the side panel assembly 200 includes a sealing plate 220. The sealing plate 220 is disposed at both ends of the second air duct 020 and matches and corresponds to the second air duct 020. The sealing plate 220 is provided with a fourth air outlet 221, which is connected to the air conditioner outlet 002. This allows the air conditioner outlet to enter the first air duct 010 and the second air duct 020 simultaneously through the inlet of the first air duct 010 and the fourth air outlet 221 of the second air duct 020, thereby increasing the airflow in the second air duct 020 and making the air delivery more uniform.

[0047] like Figure 3-4 As shown, in some embodiments of this utility model, the sealing plate 220 is further provided with a first opening 222. The first opening 222 allows a passageway for wiring of the carriage facilities to be formed within the second air duct 020, eliminating the need for separate conduit assemblies, thus enhancing component integration and further reducing the space occupied by the components. For example... Figure 6 and Figure 8 As shown, the side panel assembly 200 is also provided with a second port 211. The second port 211 can be used to install facilities required by the carriage, such as speakers. The power supply or signal supply line to the facility enters through the first port 222 on the cover plate 220 to supply power or communication to the facility installed at the second port 211 on the side panel 210. There is no need to occupy additional space to set up additional facilities. It has a high degree of integration and a small space ratio.

[0048] In some embodiments provided by this utility model, an insulation layer (not shown) is also laid on the lower side of the vehicle body roof 001. The insulation layer reduces the heat transfer from the external environment to the top of the vehicle body, while enhancing the insulation function of the first air duct 010 and the second air duct 020.

[0049] like Figure 2 , Figure 8 As shown, the integrated structure of the roof air duct of the rail vehicle provided by this utility model also includes a sealing element 300. The sealing element 300 is disposed between the side plate assembly 200 and the car body top cover 001 along the X direction. The sealing element 300 can be made of rubber strip, which improves the sealing performance of the second air duct 020 and ensures that the second air duct 020 does not leak air.

[0050] The above provides a detailed description of an integrated roof-mounted air duct structure for rail vehicles provided by this utility model. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The descriptions of the embodiments above are merely for the purpose of helping to understand the core ideas of this utility model. For the sake of brevity, not all possible combinations of the various technical features in the above embodiments have been described; however, any combination of these technical features that does not contradict each other should be considered within the scope of this specification. For those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
