Description

Technical Field

[0001] This application relates to the field of rail vehicle technology, and in particular to a rail vehicle and its driver's cab. Background Technology

[0002] In the driver's cab of a rail vehicle, the partition wall is the main load-bearing and sealing structure at the front of the cab, used to separate the car body space from the front section of the vehicle.

[0003] In the existing structural design of the driver's cab, the partition wall is set as a double-layer profile wall. The partition wall of this structure is relatively heavy, generally accounting for 20% to 30% of the overall weight of the driver's cab. The heavy partition wall cannot meet the design requirements of the current trend of lightweight development of rail vehicles. At the same time, because the partition wall is relatively bulky, it is inconvenient to adjust during the installation process. Summary of the Invention

[0004] The purpose of this application is to provide a rail vehicle and its driver's cab. By optimizing the structure of the partition wall of the driver's cab, the weight of the partition wall can be reduced to meet the development trend of lightweight rail vehicles. At the same time, the partition wall is easy to adjust during installation.

[0005] To address the aforementioned technical problems, this application provides a driver's cab for a rail vehicle, comprising a driver's cab body and a partition wall. The partition wall is made of composite material, and its outer contour conforms to the shape of the driver's cab body. The partition wall includes an integrally formed main wall, which comprises a first wall portion and a second wall portion. The first wall portion is perpendicular to the vehicle body underframe and is sealed to the vehicle body underframe. The second wall portion bends from the top of the first wall portion toward the front of the vehicle, and its peripheral wall is sealed to the driver's cab body.

[0006] The partition wall of the driver's cab of this rail vehicle is made of composite material. On the one hand, this reduces the weight of the partition wall and makes it easier to adjust its position during installation. On the other hand, due to the composite material, the molding characteristics of the composite material allow the main wall of the partition wall to be designed as a bent structure where the second wall bends from the top of the first wall towards the front of the vehicle. Furthermore, the second wall can be made into an irregular shape that matches the shape of the driver's cab body, thereby creating a clearance space between the second wall and the roof of the driver's cab body. This clearance space can expand the driver's field of vision and is beneficial to the layout of the interior space of the driver's cab.

[0007] As described above, the partition wall of the driver's cab of the rail vehicle further includes two side wall blocks, which are respectively connected to the two side walls of the first wall in the lateral direction. The side wall blocks are located close to the car body underframe, and the bottom wall of the side wall blocks is sealed to the car body underframe. The outer wall of the side wall blocks and the outer wall of the first wall are sealed to the driver's cab car body.

[0008] As described above, in the driver's cab of the rail vehicle, the side wall block is sealed to the first wall by adhesive bonding, and / or the side wall block is sealed to the driver's cab body by adhesive bonding.

[0009] As described above, in the driver's cab of the rail vehicle, the bottom end of the first wall has an extension extending toward the interior space of the car, and the extension is sealed to the underframe of the car body.

[0010] As described above, in the driver's cab of the rail vehicle, the extension is sealed to the vehicle body underframe by riveting and adhesive bonding.

[0011] As described above, in the driver's cab of the rail vehicle, a reinforcing rib is provided between the extension and the first wall portion.

[0012] As described above, the driver's cab of the rail vehicle has multiple reinforcing ribs, which are evenly arranged along the width direction of the driver's cab body.

[0013] As described above, in the driver's cab of a rail vehicle, the main wall comprises two panels and an internal core material disposed between the two panels.

[0014] As described above, in the driver's cab of the rail vehicle, the panel is made of carbon fiber or glass fiber; and / or, the internal core material is PMI foam or PET foam.

[0015] This application also provides a rail vehicle including a driver's cab, which is any of the driver's cabs described above.

[0016] Since the aforementioned driver's cab possesses the aforementioned technical effects, the rail vehicle including the driver's cab also possesses the corresponding technical effects, which will not be discussed again here. Attached Figure Description

[0028] 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.

[0029] Please refer to Figure 1 and Figure 2 , Figure 1 This is a longitudinal cross-sectional view of the driver's cab provided in one embodiment of this application; Figure 2 for Figure 1 Axonometric view of the central partition wall.

[0030] In this embodiment, the driver's cab of the rail vehicle includes a driver's cab body 10 and a partition wall 20. The perimeter of the partition wall 20 is sealed to the driver's cab body 10 to divide the interior of the driver's cab body 10 into a front section and a carriage space. The front section can be used to install relevant equipment of the rail vehicle, and the carriage space is the operating space of the driver's cab.

[0031] In this embodiment, the partition wall 20 is made of composite material, and the outer contour of the partition wall 20 is set to conform to the shape of the driver's cab body 10, so as to facilitate the sealing connection between the perimeter wall of the partition wall 20 and the driver's cab body 10, and ensure the airtight performance of the vehicle body.

[0032] The partition wall 20 includes an integrally formed main wall 21, which includes a first wall portion 211 and a second wall portion 212. The first wall portion 211 is perpendicular to the vehicle body frame 11 and is sealed to the vehicle body frame 11. The second wall portion 212 bends from the top of the first wall portion 211 toward the front of the vehicle, and the peripheral wall of the second wall portion 212 is sealed to the driver's cab vehicle body 10.

[0033] It is understandable that, due to the irregular structure of the front part of the driver's cab body 10, which is an irregular structure, the shape of the second wall 212, which is set in accordance with the shape of the driver's cab body 10, is also an irregular structure.

[0034] As mentioned above, the partition wall 20 is made of composite material, which is beneficial to the molding characteristics of composite materials and facilitates the processing of irregularly shaped second wall sections 212. Furthermore, the main wall 21 can be designed as a bent structure where the second wall section 212 bends from the top of the first wall section 211 towards the front of the vehicle. This structure creates a first space S1 and a second space S2 between the second wall section 212 and the driver's cab body 10. The first space S1 is located near the top of the vehicle, expanding the driver's field of vision. The second space S2 forms the space for the installation of related equipment at the front of the vehicle, and is connected to the existing partition wall. Compared to the wall structure, the main wall 21 of this bent structure can avoid the first wall 211 having to be set closer to the front of the car, leaving enough second space S2 to arrange related equipment, and also avoiding the problem of the underframe being extended due to the partition wall 20 being set forward. In summary, the partition wall 20 structure is conducive to the layout of the interior space of the driver's cab 10, and the streamlined design of the front of the driver's cab 10 is also more flexible. At the same time, the partition wall 20 made of composite materials is lighter in weight, which can realize the structural weight reduction of the driver's cab and meet the development trend of lightweight design of rail vehicles.

[0035] In practical applications, as the operating speed of rail vehicles increases, the streamlined shape of the driver's cab body 10 becomes more pointed, and the cabin space of the driver's cab body 10 becomes smaller. This poses a greater challenge to the layout design of spaces such as equipment installation space, maintenance space, driver's cab operation space, and driver's cab visibility space. After adopting the above-mentioned partition wall 20 structure, the arrangement of each space can be set more flexibly while ensuring sealing and load-bearing capacity.

[0036] In practical applications, the partition wall 20 can be designed with a geometric shape based on molding processes such as composite material molding or pultrusion molding to effectively utilize space and make reasonable avoidance. It can be understood that, depending on the shape design of the driver's cab body 10, the specific structure and shape of the partition wall 20 will be different for different vehicle models; the figure is only an illustrative example.

[0037] Please refer to this as well. Figures 3 to 6 , Figure 3 This is a partial front view of the partition wall in a specific embodiment; Figure 4 for Figure 3 Schematic diagram of the cross section along the AA direction; Figure 5 for Figure 3 Schematic diagram of the cross section along the BB direction; Figure 6 for Figure 3 Schematic diagram of the cross section in the CC direction.

[0038] In this embodiment, the partition wall 20 further includes two side wall blocks 22, which are respectively connected to the first wall portion 211 on both transverse side walls. The side wall blocks 22 are positioned close to the vehicle body frame 11, with their bottom walls sealed to the vehicle body frame 11. The outer walls of the side wall blocks 22 and the outer walls of the first wall portion 211 are sealed to the driver's cab body 10, providing a sealing connection to the sides of the driver's cab body 10. In other words, the structural shape of the first wall portion 211 and the two side wall blocks 22 after connection matches the cross-sectional shape of the driver's cab body 10. Here, the transverse direction of the first wall portion 211 refers to the width direction of the driver's cab body 10.

[0039] As mentioned above, the side wall block 22 can effectively adjust the installation space between the partition wall 20 and the driver's cab body 10. When there are manufacturing errors in the body, the installation requirements can be met simply by changing the side wall block 22, ensuring the airtightness of the connection between the partition wall 20 and the driver's cab body 10, and also improving the work efficiency of the partition wall 20 installation.

[0040] Obviously, the two side wall blocks 22 are also made of composite materials to facilitate structural weight reduction.

[0041] In practical applications, the side wall block 22 and the first wall portion 211 can be bonded together a second time. Here, the second bonding technology refers to the process of bonding different composite material parts that have already been cured with adhesive through a second curing process. In short, the side wall block 22 and the first wall portion 211 are sealed together by adhesive bonding.

[0042] In specific applications, the side wall block 22 and the driver's cab body 10 are also sealed and connected by adhesive bonding, such as... Figure 4 and Figure 6 As shown.

[0043] The outer wall of the side wall block 22 is sealed to the side of the driver's cab body 10, and the bottom wall of the side wall block 22 is sealed by adhesive bonding on both the side where the passenger compartment is located and the side where the front of the vehicle is located. Figure 4 and Figure 6 As shown.

[0044] The space where the side wall block 22 connects to the driver's cab body 10 is relatively narrow. In order to ensure the strength and reliability of the bonding between the side wall block 22 and the driver's cab body 10, the corresponding bonding parts can be heated and cured, for example, by using an industrial electric heating blanket to heat and cure the bonding parts.

[0045] In this embodiment, the bottom end of the first wall portion 211 has an extension portion 2111 extending toward the carriage space, that is, the extension portion 2111 faces away from the front of the vehicle. The extension portion 2111 is sealed to the vehicle body frame 11. In this way, the contact area between the first wall portion 211 and the vehicle body frame 11 can be increased, which is beneficial to improving the reliability and stability of the connection of the first wall portion 211.

[0046] Furthermore, a reinforcing rib 2112 can be provided between the extension 2111 and the first wall portion 211 to improve the structural strength of the partition wall 20.

[0047] Multiple reinforcing ribs 2112 can be provided, and the multiple reinforcing ribs 2112 are evenly arranged along the width direction of the vehicle body to ensure the uniformity of force at the connection between the first wall 211 and the vehicle body underframe 11.

[0048] In the illustrated scheme, the reinforcing rib 2112 is roughly triangular in shape. In other embodiments, the shape of the reinforcing rib 2112 may be different.

[0049] In practical applications, the first wall portion 211 on the side where the carriage space is located can be sealed and connected to the vehicle body frame 11 by a combination of adhesive bonding and riveting, and the riveting can be achieved using rivets 30. The first wall portion 211 on the side where the front of the vehicle is located can be sealed and connected to the vehicle body frame 11 by adhesive bonding.

[0050] The adhesive joint between the first wall section 211 and the driver's cab body 10 can also be heated and cured to ensure the adhesive strength.

[0051] Please refer to this as well. Figure 7 and Figure 8 , Figure 7 for Figure 2 The cross-sectional view of the partition wall shown; Figure 8 for Figure 7 A magnified view of part I in the middle.

[0052] The main wall 21 of the partition wall 20 (including the first wall part 211 and the second wall part 212) can specifically adopt a sandwich structure, including two panels 21a and an internal core material 21b disposed between the two panels 21a.

[0053] In specific applications, the board 21a can be made of carbon fiber or glass fiber, and the internal core material 21b can be made of (polymethacrylimide) PMI foam or PET (polyethylene terephthalate) foam to ensure the structural strength of the main wall 21 and improve its load-bearing capacity.

[0054] In addition to the driver's cab described above, this application also provides a rail vehicle that includes the driver's cab described in the above embodiments. Other structures of the rail vehicle can be implemented based on existing technologies, which will not be detailed here.

[0055] Since the aforementioned driver's cab has the above-mentioned technical effects, the rail vehicle including the driver's cab also has the same technical effects, which will not be discussed again here.

[0056] The foregoing has provided a detailed description of a rail vehicle and its driver's cab provided in this application. Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are merely for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make various improvements and modifications to this application without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this application.
