[0029] In order to make the technical solutions and advantages in the embodiments of the present application clearer and more understandable, the following further describes the exemplary embodiments of the present application in detail with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than an exhaustive list of all embodiments. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0030] In the process of implementing the present application, the inventors found that with the development of society and the increasing travel needs of people, the application of rail vehicles is becoming more and more popular, including long-distance ones such as high-speed trains, bullet trains, and ordinary trains, and short-distance ones such as subways, light rails, etc. For practical application needs, many electrical facilities are installed in the carriages, such as air conditioners, lighting devices, life-saving devices, and audio-video devices and charging interfaces are also installed inside passenger vehicles. Each type of device contains many pipelines and wires. To keep the inside of the carriage clean and beautiful, these pipelines and wires are arranged in the hidden space inside the carriage. The space between the carriage roof panel and the car body roof is one of the hidden spaces. The carriage roof panel is usually hoisted below the car body roof by hanging codes, so there will be a space between the carriage roof panel and the car body roof for installing electrical facilities and laying pipelines. The carriage roof panel not only serves as a mounting plate but also plays a role in shielding, making the inside of the carriage clean and beautiful. As is well known, electrical facilities will inevitably malfunction during use. If a malfunction occurs, repairs are required; even if no malfunction occurs, regular inspections and maintenance are also required to avoid affecting use. For the sake of stability, the roof panels in the prior art are usually fixed below the car body roof. Although the hidden installation space is beautiful and clean, it also has a disadvantage that it is difficult to repair.

[0031] In view of the above problems, in the embodiments of the present application, a car body roof is provided. This car body roof can be applied to rail vehicles or non-rail vehicles, and the roof can be opened to facilitate maintenance by workers. Considering most application scenarios, in the embodiments of the present application, taking the application on a rail vehicle as an example, it will be described below.

[0032] As Figures 1 to 8 shown, in this embodiment, the vehicle length direction is referred to as the longitudinal direction, the vehicle width direction is referred to as the transverse direction, the vehicle height direction is referred to as the vertical direction, the vertical direction or the vertical direction, the direction towards the interior of the car body is referred to as the inner, and the direction towards the exterior of the car body is referred to as the outer.

[0033] Taking the application on a rail vehicle as an example, this embodiment specifically describes the implementation manner of the car body roof. A rail vehicle includes at least one car body. The car body of the car body is composed of a underframe, side walls, a roof, and end walls. The side walls are longitudinally arranged on both sides of the underframe, and their lower ends are connected to the underframe and their upper ends are connected to the roof.

[0034] The car body roof of this embodiment includes a middle roof 341 and side roofs 342 arranged inside the car body. As Figures 1 to 4 shown, the middle roof 341 is connected to the roof 23 of the vehicle; the side roofs 342 are symmetrically arranged on both sides of the middle roof 341 with the longitudinal central axis of the middle roof 341 as the axis of symmetry. One side of the side roof 342 is rotatably connected to the side wall 25 of the vehicle, and the other side of the side roof 342 is openably connected to the middle roof 341.

[0035] The part where the side roof 342 is connected to the side wall 25 can be connected by a hinge type, or can be connected by a rotating shaft; it can also be in the form of using a bracket to fixedly connect to the side beam 25, and the hinge structure is arranged on the bracket. When the side roof 342 and the middle roof 341 are opened, the side roof 342 can rotate in the vertical direction around its connection point until it encounters the side wall. At this time, an opening with the same width as the side roof will be opened, and maintenance personnel can lean into the space between the middle roof and the roof from here to perform operations.

[0036] 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.

[0037] 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 Figure 5 and Figure 6 As 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.

[0038] 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.

[0039] This kind of tension lock has a relatively simple structural form, with fewer components, easy to process and install, low cost, and can achieve the purpose of locking well. When it needs to be opened, it can be easily opened even without a key.

[0040] Regarding the connecting profile, this embodiment provides a specific implementation method, such as Figure 7 shown in the figure: The top plate installation profile includes a lighting installation profile 331 and a tension lock installation profile 334 that are connected to each other. Among them, one side of the lighting installation profile 331 close to the middle top plate 341 extends upward and then contacts the lower side surface of the middle top plate 341, and one side of the lighting installation profile 331 close to the side top plate 342 extends horizontally and then contacts the upper side surface of one side of the side top plate 342. The tension lock installation profile 334 is arranged between the lighting installation profile 331 and the vehicle roof.

[0041] 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, covering the relatively wide gap at the connection between the side top plate 342 and the middle top plate 341 and the tension lock structure provided at this place. When observed from the inside of the carriage, the specific structure of the tension lock cannot be seen, nor can the gap at the connection be seen, ensuring the cleanliness and beauty of the interior of the carriage. At the same time, using a profile structure, the tension lock structure and the lighting device can be assembled onto the vehicle roof at one time after being installed, improving the installation efficiency.

[0042] Furthermore, a chute is provided on the side of the lighting installation profile 331 facing the vehicle roof, and the tension lock installation profile 334 is snapped into the chute. One side edge of the tension lock installation profile 334 extends towards 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 chute, which is simple and convenient for installation and conducive to modular assembly.

[0043] Furthermore, a lamp shade buckle is provided on the lower side of the lighting installation profile 331, and the lamp shade buckle is connected to the lamp shade 333. A top plate lighting assembly 33 is arranged inside the lamp shade. A chute connection method can also be adopted between the lamp shade 333 and the lamp shade buckle for convenient installation and maintenance.

[0044] The top of the tension lock installation profile 334 is connected to the lower end of the top plate lifting lug 343, and the upper end of the top plate lifting lug 343 is connected to the vehicle roof. Since there is only one edge connection between the top plate installation profile and the middle top plate, the stiffness and strength are not enough. Therefore, the top plate installation profile is also fixed to the top plate using the top plate lifting lug, which can increase the reliability of the carriage top plate structure.

[0045] Specifically, the side top plate 342 is connected to the side wall of the vehicle through a side top plate rotating shaft.

[0046] Further, a side lighting assembly 345 is also provided at the connection between the side roof panel 342 and the vehicle side wall 25. Specifically, the side roof panel 342 is connected to the side wall profile 348 through a side roof panel rotating shaft. An illumination installation groove with an upward opening is provided at the bottom end of the side wall profile 348, and the side lighting assembly 345 is arranged in the illumination installation groove, emitting light upward. The side walls of the illumination installation groove block the light to prevent the light from directly shining into people's eyes and improve comfort.

[0047] In the prior art, the lighting devices provided on the roof panel are usually fixed by bolts. On the one hand, it requires operators to tighten the bolts one by one with tools, which is time-consuming and laborious and has low efficiency. Moreover, when the lighting device fails, disassembly and assembly are relatively inconvenient. On the other hand, during the vehicle driving process, the bolts are prone to loosen, causing the lighting device to have the possibility of falling off.

[0048] In view of the above problems, the embodiments of the present application also improve the roof panel and the lighting assembly: as Figures 9 to 12 shown, the roof panel lighting assembly 33 includes: an illumination installation profile 331 and a lamp 332. Among them, the illumination installation profile 331 is arranged at the end of the roof panel; an illumination profile lamp installation part 3313 is provided on the illumination installation profile 331. The lamp 332 is provided with a lamp buckle 3323; the lamp buckle 3323 is clamped on the illumination profile lamp installation part 3313.

[0049] In the specific implementation process, the illumination installation profile 331 is arranged at the end of the roof panel, and the illumination profile lamp installation part 3313 is provided on the illumination installation profile 331; the lamp buckle 3323 is integrally arranged on the lamp 332, and the lamp buckle 3323 is clamped on the illumination profile lamp installation part 3313. Applying a pulling force or a pushing force to the lamp 332 can realize the assembly and disassembly of the lamp 332 and the illumination installation profile 331, which is simple and fast, without other tools, and improves the assembly efficiency and maintenance efficiency.

[0050] In the embodiment of the present application, the lamp 332 includes a lamp installation bracket 3321, one end of which is provided with a light source installation groove, and the other end opposite to the light source installation groove is provided with a lamp buckle 3323. The light source 3322 is arranged in the light source installation groove; the light emitting surface of the light source 3322 faces the opening direction of the light source installation groove.

[0051] In the specific implementation process, as Figure 10 shown, a light source installation groove is provided at one end of the lamp installation bracket 3321, the light source 3322 is arranged in the light source installation groove, and a lamp buckle 3321 is provided at the other end opposite to the light source installation groove. The lamp buckle 3323 is clamped on the illumination profile lamp installation part 3313, and the lamp 332 is installed by pressing or spreading the end of the lamp installation bracket 3321 provided with the light source installation groove.

[0052] In the embodiment of the present application, the cross-section of the lamp clip 3323 is an arc shape; the cross-section of the lighting profile lamp mounting portion 3313 is an arc shape, and the lamp clip 3323 can be clamped on the outer side of the lighting profile lamp mounting portion 3313.

[0053] In a specific implementation process, the cross-section of the lamp buckle 3323 is an arc shape, specifically a major arc, and the lamp buckle 3323 can be slightly deformed by an external force.

[0054] In the embodiment of the present application, the lighting installation profile 331 includes a lighting profile main body 3311; a lighting profile top plate installation portion 3312, which is disposed at one end of the lighting profile main body 3311 and is used to be connected to the top plate;

[0055] The lighting profile lamp installation portion 3313 is arranged on the other end of the lighting profile main body 3311 away from the lighting profile top plate installation portion 3312; the lighting profile lamp installation portion 3313 is provided on the lighting profile lamp installation portion 3313, and the lighting profile lamp installation portion 3313 protrudes in a direction away from the lighting profile main body.

[0056] In the specific implementation process, the lighting profile top plate mounting portion 3312 is a straight-line mounting plate, such as Figure 3 As shown, the left end of the lighting profile top plate mounting portion 3312 is used to connect to the top plate.

[0057] In the embodiment of the present application, the lamp 332 further includes a lampshade 333 , which is arranged on the outside of the light source 3322 ; the lampshade 333 is a structure with one end closed and the other end open, and its open end is connected to the lighting installation profile 331 .

[0058] In the specific implementation process, the lampshade 333 is clamped on the lighting installation profile 331. Specifically, two clamping tongues are provided at the end of the lighting installation profile 331, respectively located at the upper and lower sides of the lighting profile lamp installation part 3313. The lampshade 333 is a U-shaped structure, and hooks are provided at both ends. During the assembly process, a thrust is applied to the lampshade 333, so that the hooks and the clamping tongues on it are hooked with each other, so that the lampshade 333 is clamped and fixed on the lighting installation profile 331.

[0059] In the embodiment of the present application, the lighting profile lamp mounting portion 3313 is a full-length structure extending along the length direction of the vehicle. The lamp buckle 3323 is a full-length structure extending along the length direction of the vehicle, and one lamp mounting bracket 3321 is provided with one lamp buckle 3323; or one lamp mounting bracket 3321 is provided with multiple lamp buckles 3323, and the multiple lamp buckles 3323 are sequentially spaced along the length direction of the vehicle.

[0060] In the specific implementation process, the lighting profile lamp installation part 3313 and the lamp buckle 3323 are both of a general structure extending along the vehicle length direction. One lamp installation bracket 3321 can be provided with one lamp buckle 3323 or multiple lamp buckles 3323 according to the layout requirements of the rail vehicle carriage. The multiple lamp buckles 3323 are arranged along the rail vehicle length direction and are spaced apart from each other.

[0061] In the embodiment of the present application, the top plate is the side top plate 342; the vehicle top plate assembly further includes a middle top plate, and the side top plate 342 is arranged on both sides of the middle top plate along the vehicle width direction. The top plate lighting assembly is arranged at the position between the side top plate 342 and the middle top plate; the top of the lighting installation profile extends to form a middle top plate connection part connected to the middle top plate.

[0062] In the specific implementation process, as shown in the figure, the top plate is the side top plate 342, the vehicle top plate assembly further includes a middle top plate, and the side top plate 342 is arranged on both sides of the middle top plate along the vehicle width direction, and the top plate assembly is arranged at the position between the side top plate 342 and the middle top plate.

[0063] In the assembly process of the embodiment of the present application, the lamp buckle 3323 is oriented towards the lighting profile lamp installation part 3313, abuts against the lighting profile lamp installation part 3313 and applies a thrust force. The arc surface of the lighting profile lamp installation part 3313 generates an outward acting force on both ends of the lamp buckle 3323, causing the lamp buckle 3323 to expand and deform and accumulate elastic potential energy. When the opening of the lamp buckle 3323 is larger than the maximum diameter of the lighting profile lamp installation part 3313, the lighting profile lamp installation part 3313 enters the lamp buckle 3323, and no longer applies a force to the lamp buckle 3323. The lamp buckle 3323 retracts and wraps around the outside of the lighting profile lamp installation part 3313, and the rebounding force of the lamp buckle 3323 clamps the lighting profile lamp installation part 3313 inward, preventing the lighting profile lamp installation part 3313 from disengaging from the lamp buckle 3323 without external force, and realizing the clamping and fixing of the lamp installation bracket 3321 and the lighting installation profile 331.

[0064] In the disassembly process of the embodiment of the present application, a pulling force away from the lighting installation profile 331 is applied to the lamp installation bracket 3321. The arc surface of the lighting profile lamp installation part 3313 generates an outward acting force on both ends of the lamp buckle 3323, causing the lamp buckle 3323 to expand and deform and accumulate elastic potential energy. When the opening of the lamp buckle 3323 is larger than the maximum diameter of the lighting profile lamp installation part 3313, the lighting profile lamp installation part 3313 disengages from the lamp buckle 3323, realizing the separation of the lamp installation bracket 3321 and the lighting installation profile 331.

[0065] For the above disassembly and assembly process, only push or pull the lamp mounting bracket 3321 along the disassembly and assembly direction, which is simple and fast. No special disassembly and assembly tools are required, and it can be disassembled and assembled casually, which is convenient and fast.

[0066] Moreover, the acting force of the arc surface of the lighting profile lamp mounting part 3313 on the lamp buckle 3323 is uniform, which can avoid the problem that a certain part of the lamp buckle 3323 is stressed too much and breaks.
