[0002] The equipment compartment of a rail vehicle is a compartment space located at the bottom of the rail vehicle and is used to place equipment.

[0003] The equipment compartment is a non-load-bearing structure. Its enclosed design aims to reduce air resistance during train operation and enhance protection for the undercarriage suspension, while also enhancing the aesthetics of the train's exterior. The design of the equipment compartment must ensure ease and reliability in installation and maintenance of the undercarriage suspension equipment. It also requires a certain level of mechanical strength to protect the equipment within from impact and interference from foreign objects such as rain, snow, and wind.

[0004] To ensure mechanical strength, conventional equipment cabins typically use welded metal structures. However, these structures present numerous challenges, including heavy weight, structural safety issues such as weld cracking, inconvenient maintenance and increased costs, ventilation and heat dissipation issues, bolted joint safety issues such as loosening and falling out, twist-lock doors that can loosen and open, posing safety hazards, and snow accumulation in the bogie area. Using composite materials for equipment cabins also presents challenges such as high cost and poor stability. Summary of the Invention

The first slide extends in the first direction on the side wall. A plurality of second slides are formed on the side wall and extend downward from the first slide, and the ends of the second slides extend horizontally. A plurality of third slides extend upward from the first slide to the upper wall. The slider slides from the upper wall into the third slide, passes through the first slide, and slides into the end of the second slide, so that the bottom plate is in the first state; or, the bottom plate is slid from the first state into the first slide along the second slide, and slides to the top of the other bottom plate through the first slide, or slides out from between the two support beams through the third slide.

[0010] According to an embodiment of the present disclosure, an extension portion is formed on the bottom wall and extends toward the adjacent support beam, and a surface of the extension portion is recessed downward to form a groove extending along the first direction;

[0011] Sealing strips are installed at the lower parts of the two side edges of the bottom plate extending along the first direction, and the sealing strips are matched with the grooves to seal the bottom plate and the support beam in the first state.

[0012] According to an embodiment of the present disclosure, in a plane perpendicular to the first direction, the cross-sectional shape of the groove is trapezoidal, so as to cooperate with the sealing strip to maintain the bottom plate in the first state.

[0013] According to an embodiment of the present disclosure, sealing members are respectively provided on both sides of the bottom plate perpendicular to the first direction. In the first state, two adjacent bottom plates are sealed and combined by squeezing the two sealing members.

[0014] According to an embodiment of the present disclosure, a handle is provided on the lower side of the base plate, so that the base plate can be slid between two adjacent support beams by operating the handle.

[0015] According to an embodiment of the present disclosure, the base plate includes an upper plate, a lower plate, and a plurality of support members. The lower plate is disposed opposite to the upper plate, and the plurality of support members are disposed at intervals between the upper plate and the lower plate.

[0068] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present disclosure. In the detailed description below, for ease of explanation, many specific details are set forth to provide a comprehensive understanding of the embodiments of the present disclosure. However, it is apparent that one or more embodiments may also be implemented without these specific details. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present disclosure.

[0069] The terms used herein are only for describing specific embodiments and are not intended to limit the present disclosure. The terms "comprise," "include," etc. used herein indicate the presence of the features, steps, operations, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, or components.

[0070] All terms used herein (including technical and scientific terms) have the meanings commonly understood by those skilled in the art unless otherwise defined. It should be noted that the terms used herein should be interpreted as having a meaning consistent with the context of this specification and should not be interpreted in an idealized or overly rigid manner.

[0071] When expressions such as "at least one of A, B, and C, etc." are used, they should generally be interpreted in accordance with the meaning commonly understood by those skilled in the art (for example, "a system having at least one of A, B, and C" should include but is not limited to a system having A alone, B alone, C alone, A and B, A and C, B and C, and / or A, B, C, etc.).

[0072] Figure 1 A perspective view of an equipment cabin in the related art is schematically shown.

[0073] In the process of realizing the present disclosure, it was found that Figure 1 As shown, the equipment cabin in the related art includes multiple groups of main beams 6 and multiple groups of cladding plates 7. Each group of main beams 6 includes two opposing cross beams 61, two arc-shaped side beams 62 and a vertical beam 63 connected between the two cross beams 61. The vertical beams 63 are installed between the two cross beams 61 by welding or screwing, and the side beams 62 are installed on the cross beams 61 by welding or screwing. Each group of cladding plates 7 is installed between two adjacent cross beams 61 by threaded connection. A plurality of reinforcing ribs arranged parallel to or perpendicular to the cross beams 61 are also required between the two upper cross beams 61 in the two adjacent groups of main beams 6 to ensure the supporting strength of the equipment cabin.

[0074] During maintenance, the bolts between the cladding plate 7 and the crossbeam 61 need to be removed. After the maintenance is completed, the cladding plate 7 needs to be installed between the two crossbeams 61 with bolts. This makes disassembly and assembly cumbersome and inconvenient for maintenance. In addition, the use of bolt connections is also prone to problems such as bolt loosening and falling off, affecting the structural stability and safety of the equipment compartment.

[0075] In this solution, the vertical beams 63 and side beams 62 are mounted between the two cross beams 61 by welding or screwing. Bolting is also subject to problems such as loosening and falling bolts, while welding also carries the risk of weld cracking, adversely affecting the normal operation of the rail vehicle. While the solution of using cross beams 61, side beams 62, vertical beams 63, and reinforcing ribs enhances structural strength, it also makes the equipment compartment structure more complex, hindering the lightweight design of the rail vehicle.

[0076] Figure 2 Schematically shows a bottom view of the equipment cabin structure according to an embodiment of the present disclosure, Figure 3 Schematically shows a first partial installation diagram of the equipment cabin structure according to an embodiment of the present disclosure, Figure 4 Schematically shows a second partial installation diagram of the equipment cabin structure according to an embodiment of the present disclosure, Figure 5 A partial cross-sectional view of an equipment cabin structure according to an embodiment of the present disclosure is schematically shown.

[0077] As one aspect of the embodiments of the present disclosure, there is provided an equipment cabin structure, such as Figures 2 to 5 As shown, the equipment cabin structure includes a plurality of support beams 1 and a plurality of groups of bottom plates 2. The plurality of support beams 1 extend in parallel in the first direction of the rail vehicle and are arranged at intervals, and both ends of each support beam 1 are installed at the lower part of the chassis of the rail vehicle. Each group of bottom plates 2 is slidably installed between two adjacent support beams 1. Specifically, when the rail vehicle is in operation, the plurality of bottom plates 2 of each group of bottom plates 2 are arranged in sequence along the first direction, and the plurality of bottom plates 2 are in a first state in which the accommodation space at the lower part of the chassis is closed; when the rail vehicle is in maintenance, at least one bottom plate 2 moves to the top of the other bottom plates 2 located between the two support beams 1 or slides out from between the two support beams 1 by sliding relative to the support beam 1, so that at least one bottom plate 2 is in a second state in which the accommodation space is opened.

[0078] According to the equipment compartment structure of the disclosed embodiment, by slidably mounting each set of bottom plates 2 between two adjacent support beams 1, when the rail vehicle is in operation, the multiple bottom plates 2 of each set of bottom plates 2 can be arranged sequentially along a first direction, so that the multiple bottom plates 2 are in a first state, sealing the storage space below the chassis. When the rail vehicle is undergoing maintenance, at least one bottom plate 2 can be moved relative to the support beams 1 to be above the other bottom plates 2 located between the two support beams 1, or slid out from between the two support beams 1, so that the at least one bottom plate 2 is in a second state, opening the storage space. The sliding design of the bottom plates 2 allows the bottom plates 2 to be easily removed during maintenance, opening the storage space and facilitating maintenance and repair of the equipment below the chassis, thereby improving maintenance efficiency and reducing maintenance difficulty and cost. When the bottom plates 2 are in the open state, ventilation within the equipment compartment is enhanced, facilitating heat dissipation, thereby resolving ventilation and heat dissipation issues that may exist in traditional equipment compartments. When the train is in operation, the bottom plates 2 protect the internal equipment from the external environment while also maintaining the rail vehicle's aesthetic appearance.

[0079] According to an embodiment of the present disclosure, the first direction may be a length direction or a width direction of the rail vehicle.

[0080] According to an embodiment of the present disclosure, the equipment in the equipment compartment may include electrical traction and auxiliary system equipment, such as a VVVF box (variable frequency and voltage controller), a resistance brake box, an SIV box (static inverter), etc.

[0081] like Figure 2 As shown, both ends of the support beam 1 are respectively mounted on the side beams 31 of the underframe 3 of the rail vehicle, and the support beam 1 is located above the track.

[0082] Figure 6 A cross-sectional view schematically illustrates the installation of a support beam and a connecting member according to an embodiment of the present disclosure. Figure 7 A perspective view of a connector according to an embodiment of the present disclosure is schematically shown.

[0083] like Figure 6 As shown, the support beam 1 is mounted on the side beam 31 through the connecting member 5. Figure 7 As shown, the connector 5 includes a main body 51 and two cantilevers 52. The two cantilevers 52 extend downward from the main body 51 and are each provided with a second through-hole 54. Bolts pass through the second through-holes 54 to secure the ends of the two side walls of the support beam 1 to the connector 5. The main body 51 also has a first through-hole 53. Bolts pass through the first through-holes 53 to secure the connector 5 to the side beam 31.

[0084] Figure 8 Schematically shows a side view of a support beam according to an embodiment of the present disclosure, Figure 9A partial perspective view of a support beam according to an embodiment of the present disclosure is schematically shown.

[0085] According to the embodiments of the present disclosure, Figure 4 、 Figure 8 and Figure 9 As shown, the support beam 1 includes a main body and two transition parts. The two transition parts extend upward from both ends of the main body respectively.

[0086] Furthermore, the main body may be rod-shaped, and the transition portion may be arc-shaped. The main body may be substantially parallel to the plane where the underframe 3 of the rail vehicle is located.

[0087] According to an embodiment of the present disclosure, the support beam 1 may be an integrally formed structure.

[0088] In the exemplary embodiment, the support beam 1 can be formed by bending a profile. This eliminates welds and cracking risks, ensuring safety. Furthermore, the bent profile has a smooth cross-section, reducing wind resistance. The bent profile is lightweight and easy to install and remove. Compared to traditional support beams, this reduces the weight of the support beam and improves the stability and safety of the equipment compartment.

[0089] In an illustrative embodiment, aluminum profiles may be used and bent to form support beams 1 as the skeleton of the equipment cabin structure without using welded structures or carbon fiber structures.

[0090] In an illustrative embodiment, the base plate 2 may be made of aluminum profiles.

[0091] Figure 10 Schematically shows Figure 9 A partial enlarged view of part B of the support beam is shown. Figure 11 Schematically shows Figure 8 A cross-section along AA of the support beam is shown.

[0092] According to the embodiments of the present disclosure, Figures 5 to 11 As shown, each support beam 1 includes a bottom wall 12, an upper wall 13 and two side walls 14. The upper wall 13 is arranged below the bottom wall 12, and the two side walls 14 are connected between the upper wall 13 and the bottom wall 12, wherein the slideway is opened on the side walls 14 and the upper wall 13 of the support beam 1.

[0093] According to the embodiments of the present disclosure, the upper wall 13, bottom wall 12, and two side walls 14 form a closed box-shaped structure, giving the support beam 1 high rigidity and stability, effectively resisting external loads and vibration. The provision of a slideway allows the floor 2 of the equipment compartment to slide along the support beam 1, facilitating the installation, maintenance, and replacement of equipment, and improving efficiency during maintenance or overhaul. Furthermore, this structure of the support beam 1 reduces overall weight while maintaining strength, thereby improving the energy efficiency of rail vehicles.

[0094] According to the embodiments of the present disclosure, Figure 5 、 Figure 10 and Figure 11 As shown, the support beam 1 further includes a top wall 15 and two connecting walls 16. The top wall 15 is disposed above the upper wall 13, and the two connecting walls 16 are connected between the top wall 15 and the upper wall 13. The distance between the two connecting walls 16 is smaller than the distance between the two side walls 14.

[0095] In this embodiment, the distance between the two connecting walls 16 is smaller than the distance between the two side walls 14, and the distance between the top wall 15 and the upper wall 13 is larger than the slider 21 (which will be discussed later). Figure 12 and Figure 13 Detailed description) in the height direction, so that the space between the top wall 15 and the upper wall 13 allows the slider 21 to slide into or out of the slideway from the upper wall 13.

[0096] In such an embodiment, by providing the top wall 15, the top support of the support beam 1 is increased, making the structure of the entire support beam 1 more solid and better able to withstand external loads and vibrations. The connecting wall 16 strengthens the connection between the top wall 15 and the upper wall 13, thereby improving the stability of the entire support beam 1. The provision of the top wall 15 and the connecting wall 16 helps to better distribute the weight of the equipment in the equipment cabin, reduce the pressure on a single support point, and thus extend the service life of the support beam 1. The top wall 15 and the connecting wall 16 can provide additional fixing points for the equipment inside the equipment cabin, making the installation of the equipment more stable. In addition, the top wall 15 can prevent foreign matter from entering the equipment cabin from above, protecting the internal equipment from damage.

[0097] According to the embodiments of the present disclosure, Figures 8 to 11 As shown, the slide 11 includes a first slide 111, a plurality of second slides 112, and a plurality of third slides 113. The first slide 111 extends in a first direction on the side wall 14. The plurality of second slides 112 are formed on the side wall 14 and extend downward from the first slide 111. The ends of the second slides 112 extend horizontally. The plurality of third slides 113 extend upward from the first slide 111 to the upper wall 13. The slider 21 slides from the upper wall 13 into the third slide 113, passes through the first slide 111, and slides into the ends of the second slides 112, placing the bottom plate 2 in the first state. Alternatively, the bottom plate 2 is slid from the first state along the second slide 112 into the first slide 111, and slides through the first slide 111 to the top of another bottom plate 2, or slides out from between the two support beams 1 through the third slide 113.

[0098] According to an embodiment of the present disclosure, the distance between the ends of the first slideway 111 and the second slideway 112 is greater than the thickness of the bottom plate 2 , so that the bottom plate 2 can be placed above another bottom plate 2 on the support beam 1 .

[0099] According to the embodiments of the present disclosure, a first slideway 111, multiple second slideways 112, and multiple third slideways 113 provide a flexible means of movement for the floor 2 of the equipment compartment of a rail vehicle. By combining different slideways, the floor 2 can move in multiple directions, achieving a variety of different states and meeting different operational requirements (e.g., normal operation, routine maintenance, or overhaul).

[0100] In such an embodiment, the slider 21 can slide from the upper wall 13 into the third slide 113, and then slide through the first slide 111 into the end of the second slide 112, so that the equipment compartment remains closed and compact when the train is running. When it is necessary to inspect the equipment in the equipment compartment, the slider 21 can slide along the second slide 112 into the first slide 111, and slide through the first slide 111 to the top of the other bottom plate 2, so that the bottom plate 2 can be easily converted from a closed state (first state) to an open state, making it easier for maintenance personnel to access the equipment in the equipment compartment. When it is necessary to overhaul the equipment in the equipment compartment, the slider 21 can slide along the second slide 112 into the first slide 111, slide through the first slide 111 to the third slide 113, and slide out from the upper wall 13 along the third slide 113, removing the bottom plate 2 from between the two support beams 1, making it easier for maintenance personnel to access the equipment in the equipment compartment.

[0101] According to an embodiment of the present disclosure, the upper end of the third slideway 113 and the upper end of the second slideway 112 are staggered in the height direction.

[0102] According to the embodiments of the present disclosure, Figure 10 As shown, the second slideway 112 includes a downwardly extending first section of the second slideway 112 and a horizontally extending second section of the second slideway 112. The size of the first section of the second slideway 112 gradually decreases from top to bottom. The first section of the second slideway 112 can serve as a guide to ensure that the slider 21 stably enters the horizontally extending second section of the second slideway 112 during the sliding process, thereby reducing deviation and jamming during the sliding process.

[0103] Furthermore, if Figures 8 to 10 As shown, the first section of the second slideway 112 extends obliquely downward from the first slideway 111. The first section of the second slideway 112 used for mounting the same base plate 2 has the same extending direction.

[0104] In an illustrative embodiment, the extension directions of the first section of the second slide 112 used to install two adjacent base plates 2 are different, so as to guide the slider 21 on the same base plate 2 to accurately enter the corresponding second slide 112, thereby reducing the possibility of installation deviation and error of the base plate 2.

[0105] In an illustrative embodiment, Figure 9From the perspective shown, the three first sections of the second slideways 112 for mounting the first base plate 2 extend obliquely to the left, and the three first sections of the second slideways 112 for mounting the second base plate 2 extend obliquely to the right.

[0106] In an exemplary embodiment, the number of the first slideway 111 on each side wall 14 may be one, and the first slideway 111 extends along the length direction of the support beam 1 .

[0107] In another exemplary embodiment, there may be multiple first slideways 111 on each side wall 14, spaced apart along the length of the support beam 1. For example, one first slideway 111 may be shared by every two bottom plates 2, or one first slideway may be shared by every three bottom plates 2. It is understood that the number of first slideways 111 may be designed according to actual needs.

[0108] According to an embodiment of the present disclosure, the connection between the first slideway 111 and the second slideway 112 is arc-shaped, and the connection between the first slideway 111 and the third slideway 113 is arc-shaped, ensuring that the slider 21 slides smoothly in the slideway.

[0109] Figure 12 Schematically shows a perspective view of a base plate according to an embodiment of the present disclosure, Figure 13 Schematically shows Figure 12 A partial enlarged view of portion C of the bottom plate is shown.

[0110] According to the embodiments of the present disclosure, Figure 12 and Figure 13 As shown, each base plate 2 is provided with a plurality of sliders 21, which extend outward from both sides of the base plate 2 near the support beam 1. A slideway 11 is formed on the sidewall 14 of each support beam 1 facing the sliders 21, and the sliders 21 extend into the slideway, which restricts the position of the base plate 2 relative to the support beam 1.

[0111] According to the embodiments of the present disclosure, the cooperation between the slider 21 and the slideway can precisely limit the position of the base plate 2, preventing unnecessary movement of the base plate 2 during vehicle operation and ensuring the safety and stability of the equipment. Furthermore, the cooperation between the slider 21 and the slideway makes the installation and removal of the base plate 2 easier and faster, reducing the time required for maintenance and replacement of the equipment.

[0112] According to an embodiment of the present disclosure, the slider 21 may be integrally formed with each base plate 2 , or may be mounted on the base plate 2 by screwing, welding, or riveting.

[0113] According to the embodiment of the present disclosure, the design of the sliding base plate 2 realizes the modularization of the equipment cabin, so that the base plate 2 can be replaced individually without the need to dismantle the equipment cabin as a whole, thereby improving the flexibility and convenience of maintenance.

[0114] In an exemplary embodiment, eight sliders 21 may be provided on each base plate 2, with four sliders 21 provided on each side of the base plate 2 close to the support beam 1. It is understood that the number of sliders 21 may be adjusted according to the size of the base plate 2.

[0115] In an exemplary embodiment, the slider 21 may be a stainless steel pin fixed to a support member 27 (described in detail later) of the bottom plate 2 by rivets.

[0116] According to the embodiments of the present disclosure, Figure 5 、 Figures 9 to 11 As shown, bottom wall 12 is formed with an extension 121 extending toward the adjacent support beam 1. The surface of extension 121 is recessed downward to form a groove 122 extending along the first direction. Sealing strips are installed at the lower portions of both side edges of bottom plate 2 extending along the first direction. The sealing strips mate with grooves 122 in a concave-convex manner, ensuring a sealed connection between bottom plate 2 and support beam 1 in the first state.

[0117] According to the embodiments of the present disclosure, by providing a sealing strip between the base plate 2 and the support beam 1, and by ensuring that the sealing strip mates with the groove 122, the gap between the base plate 2 and the support beam 1 can be effectively sealed, preventing moisture, dust, and other foreign matter from entering the equipment compartment and protecting the internal equipment. Furthermore, the sealing strip acts as a buffer, reducing direct impact between the base plate 2 and the support beam 1 and protecting the base plate 2 and the support beam 1 from damage. The provision of the sealing strip can absorb and reduce vibration and noise generated during rail vehicle operation, thereby improving ride comfort.

[0118] According to the embodiments of the present disclosure, Figure 5 and Figure 10 As shown, in a plane perpendicular to the first direction, the cross-section of the groove 122 is trapezoidal, so as to cooperate with the sealing strip to maintain the bottom plate 2 in the first state.

[0119] In this embodiment, by setting the cross-sectional shape of groove 122 to a trapezoidal shape, it can better match the shape of the sealing strip, forming a tighter seal, effectively preventing water, dust, and other foreign matter from entering the equipment compartment. At the same time, the trapezoidal groove 122 can provide a better fixation between the bottom plate 2 and the support beam 1, making the bottom plate 2 more stable in the first state and less likely to shift due to vehicle vibration, thereby helping to maintain the stability of the bottom plate 2 in the first state.

[0120] According to an embodiment of the present disclosure, by setting the cross-sectional shape of the groove 122 to a trapezoid, the sealing strip can cooperate with the groove 122 to lock the base plate 2 in the first state, thereby ensuring that the base plate 2 is firmly in a closed state when the rail vehicle is running, preventing accidental opening, and improving the safety of operation.

[0128] According to the embodiments of the present disclosure, Figures 12 to 14 As shown, the base plate 2 includes an upper plate 25, a lower plate 26 and a plurality of support members 27. The lower plate 26 is arranged opposite to the upper plate 25, and the plurality of support members 27 are arranged at intervals between the upper plate 25 and the lower plate 26. Among them, the slider 21 is arranged on the support member 27.

[0129] In such an embodiment, multiple support members 27 are spaced between the upper plate 25 and the lower plate 26 to help distribute the load and improve the overall stability and load-bearing capacity of the base plate 2. In addition, the support members 27 can act as shock absorbers to reduce vibration during operation of the rail vehicle.

[0130] According to an embodiment of the present disclosure, as shown in Figures 12 to 14 As shown in FIG. 27, the two sides of the bottom plate 2 perpendicular to the first direction are formed with receiving grooves 28, one end of the sealing member 23 is received in the receiving groove 28, and the other end extends outward to contact the sealing member 23 of the other bottom plate 2, thereby sealingly connecting the two adjacent bottom plates 2.

[0131] In an exemplary embodiment, eight bottom plates 2 are arranged between two adjacent support beams 1, and each bottom plate 2 can slide along the slide under the action of an external force or be removed.

[0132] Each slide on the support beam 1 can realize the functions of locking during work, sliding at will during maintenance, and facilitating the removal of the bottom plate 2 during overhaul.

[0133] According to the equipment cabin structure provided by the embodiment of the present disclosure, the connection between the support beam 1 and the bottom plate 2 does not have any auxiliary parts such as bolts and rollers, and the structure is simple.

[0134] According to the embodiment of the present disclosure, a twist lock can be added at a suitable position to prevent the sliding of the bottom plate 2 under vibration.

[0135] In such an embodiment, a mounting hole can be formed in advance on the support member where the twist lock is needed to be installed, and the twist lock can be fixed in the mounting hole. The twist lock includes a rotatable locking pin or bolt, and by rotating the locking pin or bolt, the twist lock can be inserted into the mounting hole of the support member, thereby fixing the bottom plate on the support beam.

[0136] According to the embodiment of the present disclosure, the equipment cabin structure of the embodiment of the present disclosure can be used in other areas except the wheel area.

[0137] According to the embodiment of the present disclosure, a sliding door structure can also be arranged on the bottom plate 2.

[0138] According to the embodiment of the present disclosure, the wheel periphery profile design needs to be partially strengthened to prevent vibration, and if allowed, the aluminum profile can be formed to guide the flow and reduce wind resistance.
