DETAILED DESCRIPTION

[0035] In order to make the technical solutions and advantages in the embodiments of the present application more clearly understood, the exemplary embodiments of the present application are further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than an exhaustive list of all the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0036] In the process of realizing the present application, the inventors found that in the existing rail vehicles, the luggage rack is designed to be made of a full-length profile, and the length in the longitudinal direction is relatively long. Since the luggage rack needs to bear weight when in use, in order to ensure the strength, rigidity and reliability of the luggage rack, a plurality of reinforcing ribs, or structures such as reinforcing ribs and reinforcing plates are often provided at both ends and in the middle of the luggage rack. These reinforcing structures need to be connected to the top plate at the upper end and to the load-bearing structure of the luggage rack at the lower end, so as to divide the luggage rack into multiple sections. In specific applications, the space between the top plate and the luggage rack load-bearing plate is divided into multiple sub-spaces. If the length of the luggage to be placed exceeds the length of these subspaces, it will be difficult to put it in, causing inconvenience in use; secondly, due to the existence of these partitions, the space utilization rate will also be reduced. For example, when passengers place luggage, if there is insufficient free space in the subspace to place one piece of luggage, no more luggage can be placed. When multiple subspaces have such free space, there is a waste of space. Only by removing these partitions can the space be fully utilized; finally, the main body of the existing luggage rack is a "∠"-shaped structure. When there is a slope in the roof structure, the space at the inclined roof cannot be effectively utilized. These are all problems that need to be solved urgently.

[0037] In view of the above problems, a luggage rack is provided in the embodiment of the present application, which can be applied to rail vehicles or trackless vehicles. However, since its application scenarios are mostly in rail vehicles, the application of the luggage rack in the passenger compartment of a rail vehicle is used as an example to explain its application in detail in the embodiment of the present application.

[0038] The rail vehicle includes at least one carriage, and the carriage body includes a chassis, side walls, end walls, a roof, and a top plate, wherein the side walls are vertically arranged on both sides of the chassis, and the end walls are vertically arranged at both ends of the chassis. The upper ends of the side walls and the end walls are connected to the roof, and the lower ends are connected to the chassis. The top plate includes a middle top plate and a side top plate, which are arranged in the upper part of the carriage body and fixed under the roof. The luggage rack is installed on the roof.

[0039] In this embodiment, the vehicle length direction is called longitudinal direction, the vehicle width direction is called transverse direction, the vehicle height direction is called vertical direction, vertical or vertical direction, the direction toward the inside of the vehicle is called inside, the direction toward the outside of the vehicle is called outside, the direction toward the ground is called down, and vice versa is called up.

[0040] like Figure 1 and Figure 2As shown, the luggage rack provided in this embodiment includes: a plurality of luggage rack units arranged continuously, and the plurality of luggage rack units are connected along the vehicle length direction. The luggage rack unit includes a luggage rack support 351 and a luggage rack bearing plate 352 installed on the luggage rack support for bearing luggage and other items placed thereon. The luggage rack support 351 is used to be connected to the vehicle body. One end of the luggage rack bearing plate 352 is installed on the bearing plate mounting portion, and the other end of the luggage rack bearing plate 352 extends toward the vehicle interior space.

[0041] Specifically, the luggage rack support 351 includes a luggage rack support body 3511 and a load-bearing plate mounting portion 3512. The luggage rack support body 3511 is connected to the C-shaped groove of the side wall 25. One end of the load-bearing plate mounting portion 3512 is fixed to the luggage rack support body, and the other end extends toward the interior space and covers both sides of the luggage rack load-bearing plate. The luggage rack load-bearing plate 352 is mounted on the load-bearing plate mounting portion; the luggage rack support 351 and the luggage rack load-bearing plate 352 are open structures in the longitudinal direction.

[0042] Different from the "∠"-shaped structure (the upward slanting side is the luggage rack support, and the relatively horizontal side is the bearing plate mounting portion) in the prior art in which the angle between the luggage rack support and the bearing plate mounting portion is upward, the integral luggage rack of the embodiment of the present application is slightly inclined upward compared to the horizontal plane after being installed in the vehicle body, and its luggage rack support body 3511 extends downward from the side of the bearing plate mounting portion 3512 close to its mounting surface (such as the side wall or the roof slope) and is parallel to its mounting surface. Overall, the opening direction of the angle between the luggage rack support body 3511 and the bearing plate mounting portion 3512 is downward or obliquely downward, and the size of the angle can be designed according to the position of the luggage rack mounting surface of different vehicle bodies. In the existing design, the luggage rack support body is located on the upper side of the load-bearing plate mounting portion, and it itself occupies a certain space, squeezing the available space between the luggage rack and the top plate. If it is used in a vehicle body with a sloped roof, the available space becomes very narrow, and not only the volume of the items that can be accommodated becomes smaller, but also the installation and maintenance are very inconvenient due to the angle problem. The structure of the embodiment of the present application can effectively avoid this problem.

[0043] In addition, the length of the integrated luggage rack in the embodiment of the present application in the longitudinal direction is smaller than the length of the full-length luggage rack in the prior art. The structure of the load-bearing plate mounting portion 3512 of a single luggage rack and the strength and rigidity of the luggage rack load-bearing plate 352 itself can meet the reliability requirements. Therefore, the luggage rack support 351 and the luggage rack load-bearing plate 352 are designed to be open structures in the longitudinal direction, that is, there is no structure at their ends for strengthening the reliability of the load-bearing plate and the load-bearing plate mounting portion. During assembly, multiple integrated luggage racks in the embodiments of the present application are installed in sequence in the longitudinal direction inside the vehicle body and arranged in a row to form a full-length luggage rack with no partitions in the middle. Longer items can be placed and the space can be fully utilized.

[0044] Furthermore, the luggage rack support body 3511 and the load-bearing plate mounting portion 3512 are an integrated structure. The integrated structure is conducive to processing, and is conducive to enhancing the reliability of its connection, reducing stress concentration, and increasing service life.

[0045] Furthermore, the angle between the luggage rack support body 3511 and the load-bearing plate mounting portion 3512 is an obtuse angle. Compared with the “∠”-shaped structure in the prior art, the stress at the angle of the obtuse angle structure is more dispersed, and it can withstand a greater load. It is also more suitable for a vehicle body structure with an inclined roof.

[0046] Based on the above technical scheme, an embodiment of the present application provides a specific implementation method of a load-bearing plate mounting portion 3512, wherein the load-bearing plate mounting portion 3512 is a rectangular frame structure, and a load-bearing plate mounting groove 3514 is longitudinally provided on one side close to the luggage rack support body 3511, and a luggage rack load-bearing plate clamping or fixing structure may be provided in the other three borders of the load-bearing plate mounting portion 3512, and one side of the luggage rack load-bearing plate 352 is inserted into the load-bearing plate mounting groove 3514, and the other three sides are inserted into the luggage rack load-bearing plate clamping or fixing structure.

[0047] Alternatively, a load-bearing plate mounting portion 3512 is provided at each longitudinal end of the luggage rack support body 3511, one side of the luggage rack load-bearing plate 352 is inserted into the load-bearing plate mounting groove 3514, and the two sides adjacent to the side are inserted into the card grooves of the load-bearing plate mounting portion 3512 to fix the luggage rack load-bearing plate 352.

[0048] Based on the above technical solution, the embodiment of the present application also provides a specific implementation method of the luggage rack support body 3511: the luggage rack support body 3511 is a frame structure, which includes two end frames arranged in parallel at both ends of the luggage rack support 351 and an end frame connector connecting the end frames. The end frames are arranged perpendicular to the board surface of the luggage rack bearing plate 3511.

[0049] Furthermore, the lower end of the end frame is arranged obliquely downward relative to the load-bearing plate mounting portion 3512, and the upper end is branched at a position where the extension line of the load-bearing plate mounting portion 3512 intersects. One branch extends along the extension line of the load-bearing plate mounting portion 3512 in the direction of the load-bearing plate mounting portion 3512 until it connects with the load-bearing plate mounting portion 3512 to form the bottom edge of the end frame; the other branch extends along the original extension line direction of the luggage rack support body 3511 to form the first side edge of the end frame. The first side edge of the end frame is bent at its upper end in the direction of the parallel plane of the load-bearing plate mounting portion 3512 and then extends to form the top edge of the end frame. The top edge of the end frame is bent downward at one end relative to the first side edge of the end frame until it connects with the load-bearing plate mounting portion 3512 to form the second side edge of the end frame.

[0050] Furthermore, the lower ends of the end frames are connected by connecting rods, the second sides of the two end frames are connected by end frame connecting plates, and baffles are provided on the bottom edges of the end frames and the lower ends of the end frames.

[0051] Furthermore, a side top plate mounting groove 3513 for connecting the side top plate is provided at the upper end of the end frame connecting plate.

[0052] The frame-type luggage rack support main body design can reduce weight while ensuring the overall structural rigidity, meeting the requirements of lightweight design.

[0053] Furthermore, the lower part of the luggage rack support body 3511 is integrated with a lighting strip, which can improve the lighting brightness of the passenger compartment and create a good passenger compartment atmosphere. In addition, the luggage rack bearing plate 352 can be made of high-strength and low-density plates such as PC board, polyester fiber, carbon fiber, etc., and the luggage rack support body 3511 can be made of aluminum, high-strength skeleton materials such as carbon fiber, etc., to further reduce the overall weight of the luggage rack support.

[0054] This specific embodiment also provides a car body, comprising: a base frame, side walls, end walls, a roof, a top plate and an integrated luggage rack as described above, wherein the side walls are vertically arranged on both sides of the base frame, the end walls are vertically arranged at both ends of the base frame, the upper ends of the side walls and the end walls are connected to the roof, and the lower ends are connected to the base frame, the top plate comprises a middle top plate and side top plates, which are arranged in the upper part of the car body and fixed under the roof, and the integrated luggage rack is installed on the side of the roof and connected to the side top plates.

[0055] like Figure 3 and Figure 4 As shown, the carriage 103 provided in this embodiment also includes: a car body and multiple electrical cabinets 37, and the multiple electrical cabinets 37 are arranged in the car body and distributed on the sides of the car body; the multiple electrical cabinets 37 are arranged in sequence along the length of the car and suspended in the space between the roof 23 of the car body and the side roof plate.

[0056] Compared with the traditional solution, in this embodiment, multiple smaller electrical cabinets are hoisted in the upper space of the car, and the space between the roof 23 and the side roof plate is utilized to leave most of the space at the end of the car empty to set up other components, which can improve space utilization.

[0057] Multiple electrical cabinets 37 can be arranged on one side of the carriage or on both sides. For example, in this embodiment, seven electrical cabinets are divided into two groups, one of which contains three electrical cabinets and is distributed on one side of the carriage; the other contains four electrical cabinets and is distributed on the other side of the carriage.

[0058] The electrical components installed in each electrical cabinet can be distinguished according to the strong and weak current and function. For example, the strong current control components are concentrated in one electrical cabinet, the weak current control components are concentrated in one electrical cabinet, the lighting control related components are concentrated in one electrical cabinet, and the door control related components are concentrated in one electrical cabinet. The width of each electrical cabinet can be the same, and the length is set according to the actual number of components.

[0059] The electrical cabinet 37 is a frame structure with a hollow design, which can improve the heat dissipation capacity of the electrical cabinet. For example, the electrical cabinet includes: an electrical cabinet top frame 371, an electrical cabinet bottom frame 372, a first electrical cabinet column 377, and a second electrical cabinet column 373.

[0060] The electrical cabinet top frame 371 extends horizontally and is connected to form a rectangular frame by connecting multiple square beams end to end. The electrical cabinet bottom frame 372 extends horizontally and is connected to form a rectangular frame by connecting multiple square beams end to end. The electrical cabinet bottom frame 372 is located below the electrical cabinet top frame 371.

[0061] The first electrical cabinet column 377 extends vertically, is connected between the electrical cabinet top frame 371 and the electrical cabinet bottom frame 372, and is located on the side facing the outside of the carriage. The second electrical cabinet column 373 extends vertically, is connected between the electrical cabinet top frame 371 and the electrical cabinet bottom frame 372, and is located on the side facing the inside of the carriage. The first electrical cabinet column 377 and the second electrical cabinet column 373 can also be square beams.

[0062] The size of the electrical cabinet top frame 371 and the electrical cabinet bottom frame 372 can be the same, or, in this embodiment, the size of the electrical cabinet top frame 371 is larger than the electrical cabinet bottom frame 372, and the electrical cabinet inclined frame 374 is obliquely connected between the inner end of the electrical cabinet top frame 371 and the inner end of the electrical cabinet bottom frame 372.

[0063] A slot or back plate extending in the transverse direction is provided between the first electrical cabinet column 377 and the second electrical cabinet column 373 for connecting the electrical components 375. Electrical components can also be installed on the electrical cabinet top frame 371.

[0064] The electrical cabinet is hoisted to the roof by using the vertically extending electrical cabinet hanging bracket 376, the bottom end of which is connected to the electrical cabinet top frame 371, and the top end of which is connected to the roof C-shaped groove by threaded fasteners and sliders. The electrical cabinet bottom frame 372 is connected to the side wall C-shaped groove by threaded fasteners and sliders.

[0065] On the basis of the above technical solution, this embodiment also provides a method for realizing the composition of the carriage roof:

[0066] The roof of the carriage of this embodiment comprises a middle roof plate 341 and a side roof plate 342 arranged inside the carriage. Figures 5 to 8 As shown, the middle top plate 341 is connected to the roof 23 of the vehicle; the side top plates 342 are symmetrically arranged on both sides of the middle top plate 341 with the longitudinal center axis of the middle top plate 341 as the axis, one side of the side top plate 342 is rotatably connected to the side wall 25 of the vehicle, and the other side of the side top plate 342 is openably connected to the middle top plate 341.

[0067] The part where the side roof panel 342 is connected to the side wall 25 can be connected by a hinge or a rotating shaft; it can also be fixedly connected to the side beam 25 using a bracket, and the hinge structure is set on the bracket. When the side roof panel 342 and the middle roof panel 341 are opened, the side roof panel 342 can rotate in the vertical direction with its connection as the center until it encounters the side wall. At this time, an opening with the same width as the side roof panel will be opened, and maintenance personnel can lean out from here to the space between the middle roof panel and the roof to work.

[0068] Furthermore, a top plate mounting profile is provided at the connection between the side top plate 342 and the middle top plate 341, one side of the top plate mounting profile is connected to the middle top plate 341, and the other side is openably connected to one side of the side top plate 342. The reason why the connection profile is used instead of directly connecting the middle top plate 341 and the side top plate 342 is that the middle top plate and the side top plate are respectively processed from a whole piece of profile. If the connection structure is further processed on them, there are many processing steps, and the versatility of the middle top plate and the side top plate is reduced, that is, a certain model can only use a certain model of the middle top plate. If the model is changed, the middle top plate and the side top plate must be replaced in a matching manner, which is not conducive to the modular production of rail vehicles. If the profile is used for connection, the profile can be designed according to the design requirements of different models, and can also be designed according to the installation positions of different side top plates and middle top plates, thereby improving the versatility of large components such as the middle top plate and the side top plate.

[0069] The embodiment of the present application provides a specific implementation method of an openable connection between the side top plate and the top plate mounting profile, such as Fig. 9 and Fig.10As shown, the side top plate 342 is openably connected to the top plate mounting profile via a tension lock 344. The tension lock 344 includes a tension lock tongue 3441 rotatably arranged on the top plate mounting profile and a tension lock hole 3421 fixed on an edge of one side of the side top plate. The tension lock tongue 3421 is extended into the tension lock hole 3441 to connect the side top plate 342 to the top plate mounting profile. The tension lock tongue 3421 is withdrawn from the tension lock hole 3421 to make one side of the side top plate 342 leave the top plate mounting profile, so that the side top plate 342 is opened relative to the middle top plate 341.

[0070] The tension lock 344 can be in various structural forms, as long as it is a structure that can be locked and opened, the purpose of the invention can be achieved. In this embodiment, a specific implementation method of the tension lock 344 is provided. The tension lock tongue 3441 is a stepped member with a flat cross section and a vertical portion, and the upper and lower ends of the vertical portion extend in opposite directions. The upper end of the tension lock tongue 3441, that is, the higher end of its stepped structure, that is, the first extension of the upper end of its vertical portion, is connected to the top plate mounting profile through the tension lock rotating shaft, and the lower end of the tension lock rotating shaft can be provided with a horizontal groove for inserting a flat structure or a key. The lower end of the tensioning lock tongue 3441, that is, the lower end of its stepped structure, that is, the second extension part of the lower end of its vertical part, extends toward the side top plate 342 and the thickness of the end of the second extension part is greater than the thickness of the rest of the tensioning lock tongue 3441; the tensioning lock hole 3421 is arranged on the vertical plate on one side of the side top plate 342, and is located at a position corresponding to the tensioning lock tongue 3441. The tensioning lock hole 3421 is a long hole structure with one end narrow and the other end wide. The inner width of the narrow end of the tensioning lock hole 3421 is greater than the main body thickness of the tensioning lock tongue and less than the end thickness of the tensioning lock tongue, and the inner width of the wide end of the tensioning lock hole is greater than the end thickness of the tensioning lock tongue.

[0071] This tension lock has a simple structure, few components, is easy to process and install, has low cost, and can well achieve the purpose of locking. When it needs to be opened, it can be easily opened even without a key.

[0072] Regarding the connection profile, this embodiment provides a specific implementation method, such as Fig.11 As shown: the roof mounting profile includes a lighting mounting profile 331 and a tension lock mounting profile 334 that are interconnected, wherein the lighting mounting profile 331 extends upward on one side close to the middle roof plate 341 and contacts the side lower surface of the middle roof plate 341, the lighting mounting profile 331 extends horizontally on one side close to the side roof plate 342 and contacts the side upper surface of the side roof plate 342, and the tension lock mounting profile 334 is arranged between the lighting mounting profile 331 and the roof.

[0073] One end of the lighting installation profile 331 contacts the lower side surface of the middle top plate 341, and the other end contacts the upper side surface of the side top plate 342, thereby obstructing the wider gap at the connection between the side top plate 342 and the middle top plate 341 and the tension lock structure arranged therein. When observed from inside the car, the specific structure of the tension lock and the gap at the connection cannot be seen, thereby ensuring the neatness and beauty of the interior of the car. At the same time, the profile structure is adopted, so that the tension lock structure and the lighting device can be assembled to the roof at one time after installation, thereby improving the installation efficiency.

[0074] Furthermore, a slide groove is provided on the side of the lighting installation profile 331 facing the roof, and the tension lock installation profile 334 is inserted into the slide groove, and one side of the tension lock installation profile 334 extends toward the side top plate 342 for installing the tension lock 344. During installation, the tension lock installation profile with the tension lock installed can be inserted from one end of the lighting installation profile and slid into place along the slide groove, which is simple and convenient to install and is conducive to modular assembly.

[0075] Further, a lampshade buckle is provided at the lower side of the lighting installation profile 331, and the lampshade buckle is connected to the lampshade 333, and a top plate lighting assembly 33 is arranged in the lampshade. A slide groove connection mode can also be adopted between the lampshade 333 and the lampshade buckle to facilitate installation and maintenance.

[0076] The top of the tension lock mounting profile 334 is connected to the lower end of the top plate hanging ear 343, and the upper end of the top plate hanging ear 343 is connected to the roof. Since the top plate mounting profile is connected to the middle top plate by only one edge, the rigidity and strength are not enough. Therefore, the top plate mounting profile is also fixed to the top plate using the top plate hanging ear, which can increase the reliability of the top plate assembly.

[0077] Specifically, the side top plate 342 is connected to the side wall of the vehicle via a side top plate rotation shaft.

[0078] Further, such as Fig.12 As shown, a side lighting assembly 345 is also provided at the connection between the side top plate 342 and the vehicle side wall 25. Specifically, the side top plate 342 is connected to the side wall profile 348 through the side top plate rotation shaft. The bottom end of the side wall profile 348 is provided with a lighting installation groove that opens obliquely upward. The side lighting assembly 345 is arranged in the lighting installation groove to emit light upward. The side wall of the lighting installation groove blocks the light to prevent the light from directly entering the human eye, thereby improving comfort.

[0079] In the prior art, the lighting device installed on the top plate is usually fixed with bolts. On the one hand, the operator needs to tighten the bolts one by one with tools, which is time-consuming and labor-intensive, and has low efficiency. In addition, when the lighting device fails, it is inconvenient to disassemble and assemble. On the other hand, during the driving of the vehicle, the bolts are easy to loosen, causing the lighting device to fall off.
