[0048] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The described embodiments are some, but not all, of the embodiments of this application. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0049] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0050] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0051] The terms “first,” “second,” and “third” (if any) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0052] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or display that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or display.

[0053] In related technologies, with the advocacy of "green travel" and "low-carbon environmental protection", taking public transportation has gradually become a mode of travel for people; such as subways, light rail, trams and urban rail vehicles.

[0054] Currently, the roof equipment assemblies of the aforementioned urban vehicles, such as cable trays, roof mounting brackets, mounting beams, air ducts, center roof, light strips, side roofs, and electrical components, are all installed separately and sequentially. First, the cable trays and air ducts are hoisted and secured to the vehicle body via body sliding tracks. Next, the roof mounting brackets and mounting beams are installed, with the brackets and body sliding tracks securing them to the vehicle body. Then, handrail mounting seats are installed on the beams, followed by the center roof and side roofs. Finally, lighting and cameras are installed on the center roof, and dynamic maps, speakers, and smoke detectors are installed on the side roofs.

[0055] The applicant discovered that the wiring channels, roof brackets, mounting beams, air ducts, center roof, light strips, side roofs, and electrical components on the roof of the city-area vehicles are all installed separately and sequentially to achieve their functions. All components lack modular design and are installed independently. The installation process involves first hoisting the wiring channels and air ducts, which are then connected and secured to the vehicle body via body slideways. Next, the roof brackets and mounting beams are installed, with the brackets connected and secured to the vehicle body via body slideways. Handrail mounting brackets are then installed on the brackets, followed by the center roof and side roofs. Finally, lighting and cameras are installed on the center roof, and dynamic maps, speakers, and smoke detectors are installed on the side roofs. However, because the roof components are installed sequentially, there are many installation points, resulting in long mainline operation times. Furthermore, the numerous installation interfaces and complex installation process require highly skilled workers. The multiple assembly steps lead to low assembly efficiency, high labor costs, and long vehicle production cycles. The large number of brackets connecting each component to the vehicle body increases the risk of interference, and the fact that each component is an independent hoisting system adds to the weight of the roof.

[0056] In view of this, the applicant has designed a vehicle roof structure and a rail vehicle. The vehicle roof structure and rail vehicle provided in the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0057] like Figure 1 As shown, the vehicle roof structure includes two mounting modules 10, a center roof module 20, and two side roof modules 30. The two mounting modules 10 are spaced apart along the width direction of the vehicle and are used to install on the vehicle roof. The center roof module 20 is located between the two mounting modules 10 and is installed on the two mounting modules 10. The two side roof modules 30 are located on both sides of the center roof module 20 along the width direction of the vehicle. One side of the side roof module 30 is connected to the mounting module 10, and the other side of the side roof module 30 is used to connect to the side of the vehicle. The center roof module 20 and the two side roof modules 30 together constitute the roof passenger compartment equipment.

[0058] Two mounting modules 10 are installed at intervals along the width direction of the vehicle on the roof. A center roof module 20 is located between the two mounting modules 10 and mounted on them. Two side roof modules 30 are located on either side of the two mounting modules 10 along the width direction of the vehicle, and each side roof module 30 corresponds one-to-one with a mounting module 10. One side roof module 30 is mounted on one mounting module 10 on one side and on the other side of the vehicle. The other side roof module 30 is mounted on the other mounting module 10 on one side and on the other side of the vehicle. The center roof module 20 and the two side roof modules 30 constitute the vehicle's roof equipment assembly, which integrates interior trim, lighting, air conditioning, armrest mounting, and display and announcement devices. During assembly, the central roof module 20 and the two side roof modules 30 are first assembled on the sub-assembly line. After assembly, the two mounting bracket modules 10 are installed on the vehicle roof. Then, the central roof module 20 is installed on the mounting bracket modules 10, and finally, the two side roof modules 30 are installed on the mounting bracket modules 10 respectively, thus completing the installation of the vehicle roof structure. This design requires only two mounting bracket modules 10 to install the entire structure, reducing the number of installation parts, shortening the main line operation time on the vehicle, simplifying the installation process, reducing the difficulty of worker operation, and reducing assembly steps, thereby improving assembly efficiency and shortening the vehicle production cycle. At the same time, since both the central roof module 20 and the side roof modules 30 are installed on two mounting bracket modules 10, the number of mounting brackets 11 is reduced, the interference between mounting brackets 11 is less likely, and the weight of the entire structure is also reduced, which is in line with the vehicle's lightweight design.

[0059] Understandably, the overhead cabin equipment includes a passenger information system, cabin air conditioning and lighting systems, cabin interior furnishings, and safety equipment. The passenger information system includes a passenger interface, dynamic maps, speakers, and cameras for display and announcements; the cabin air conditioning and lighting system provides ventilation and illumination; and safety equipment includes smoke and fire alarms.

[0060] like Figures 2 to 3 As shown, in some embodiments, the hanger module 10 includes a hanger 11, which has a first mounting portion 111 and a second mounting portion 112. The first mounting portion 111 and the second mounting portion 112 are arranged at intervals along the vehicle width direction. The first mounting portion 111 is connected to the center roof module 20, and the second mounting portion 112 is connected to the side roof module 30.

[0061] Specifically, the lower region of the mounting bracket 11 is provided with a first mounting part 111 and a second mounting part 112, which are spaced apart along the direction towards the center of the vehicle. The first mounting part 111 is a plate-like structure and is horizontally arranged. The first mounting parts 111 of the two mounting brackets 11 are spaced apart along the width direction of the vehicle. The two sides of the center roof module 20 are respectively mounted on the two first mounting parts 111. The second mounting part 112 is vertically arranged, and the two side roof modules 30 are respectively connected to the corresponding second mounting parts 112. The mounting bracket 11 is connected to the center roof module 20 and the side roof module 30 through the first mounting parts 111 and the second mounting parts 112 respectively. Through the dual mounting part design, the independent connection between the center roof module 20 and the side roof module 30 is realized, improving the compatibility of modular installation. Furthermore, the first mounting part 111 and the second mounting part 112 are arranged at intervals along the width direction, so that the middle top module 20 and the side top module 30 can adapt to different connection requirements, reduce the number of lifting brackets 11, reduce the overall vehicle weight, and are more in line with the concept of vehicle lightweighting.

[0062] In some embodiments, for ease of installation, the top of the vehicle is provided with a mounting groove extending along its length, the groove opening facing downwards and being T-shaped, a bolt being engaged in the mounting groove, and a mounting hole being provided on the upper side of the hanger 11, the mounting hole being adapted to the bolt, the bolt being inserted through the mounting hole to install the hanger 11 on the top of the vehicle.

[0063] Furthermore, the upper side of the mounting bracket 11 is provided with a first connecting plate and a second connecting plate, which are spaced apart along the width direction of the vehicle and also spaced apart along the vertical direction. Both the first and second connecting plates are provided with mounting holes. Correspondingly, the vehicle top is provided with two mounting slots, and the first and second connecting plates are connected to the two mounting slots respectively by bolts. This arrangement, on the one hand, improves the installation strength of the mounting bracket 11 through the double connection structure, and on the other hand, the staggered arrangement of the first and second connecting plates in the width and vertical directions of the vehicle better adapts to the curved structure of the vehicle top.

[0064] like Figures 4 to 7 As shown, in some embodiments, the top module 20 is provided with a first through hole 211; the lifting bracket module 10 also includes a nut 12 and a first screw connector 13. The nut 12 is provided in the first mounting part 111, and the first screw connector 13 passes through the first through hole 211 and is threadedly connected to the nut 12 to connect the first mounting part 111 and the top module 20.

[0065] The central support module 20 has first through holes 211 on both sides, and a nut 12 is also provided on the first mounting part 111, with the first through holes 211 corresponding to the nut 12. The first screw connector 13 is configured as a screw rod, which passes through the first through holes 211 and is threadedly connected to the nut 12, thereby achieving the purpose of connecting and fixing the central support module 20 to the lifting bracket 11. This design is simple and reliable, and also facilitates assembly.

[0066] Since the center roof module 20 extends along the length of the vehicle and has a relatively long overall length, multiple first through holes 211 are provided on both sides of the center roof module 20 to ensure its installation strength. These multiple first through holes 211 are spaced apart along the length of the vehicle. Correspondingly, multiple lifting brackets 11, nuts 12, and first screw connectors 13 are also provided. These multiple lifting brackets 11 are spaced apart along the length of the vehicle, and each lifting bracket 11 has at least one nut 12, thereby mounting the center roof module 20 on multiple lifting brackets 11. This arrangement improves the overall installation strength of the center roof module 20.

[0067] like Figure 4 and Figure 7 As shown, in some embodiments, the first mounting part 111 is provided with a receiving cavity 1111, which extends along the length direction of the vehicle. The upper and lower side walls of the receiving cavity 1111 are provided with elongated holes 1112, the cross-sectional area of ​​which is smaller than that of the receiving cavity 1111. The nut 12 is slidably installed in the receiving cavity 1111 along the length direction of the vehicle so that the position of the nut 12 along the length direction of the vehicle is adjustable.

[0068] A bracket 1113 is provided on the upper side of the first mounting part 111. The bracket 1113 is arranged in a Z-shape, and a receiving cavity 1111 is formed between the bracket 1113 and the first mounting part 111. The receiving cavity 1111 is provided through both sides along the width direction. Both the receiving cavity 1111 and the elongated hole 1112 extend along the length direction of the vehicle. The length of the elongated hole 1112 is less than the length of the receiving cavity 1111, and the width of the elongated hole 1112 is less than the width of the receiving cavity 1111, so that the cross-sectional area of ​​the elongated hole 1112 is smaller than the cross-sectional area of ​​the receiving cavity 1111. Protrusions 121 are formed on both sides of the nut 12, extending out of the receiving cavity 1111 and abutting against the side wall of the bracket 1113, thereby limiting the nut 12 and ensuring that the nut 12 can only slide along the length direction of the vehicle. The width of the elongated hole 1112 is greater than or equal to the inner diameter of the nut 12, and the width of the elongated hole 1112 is less than the outer diameter of the nut 12. This design ensures that the first screw connector 13 can smoothly pass through the elongated hole 1112 and engage with the nut 12, while also preventing the nut 12 from coming out of the elongated hole 1112. The nut 12 can slide along the length of the vehicle within the receiving cavity 1111. During the installation of the top module 20, the position of the nut 12 can be finely adjusted to accommodate manufacturing errors, improve installation adaptability, increase installation accuracy, and reduce the need for manual calibration.

[0069] In another embodiment, both the receiving cavity 1111 and the elongated hole 1112 extend along the length direction of the vehicle, and the length of the elongated hole 1112 is less than the length of the receiving cavity 1111, and the width of the elongated hole 1112 is less than the width of the receiving cavity 1111, so that the cross-sectional area of ​​the elongated hole 1112 is smaller than the cross-sectional area of ​​the receiving cavity 1111. The width of the receiving cavity 1111 is adapted to the outer diameter of the nut 12, so that the outer side of the nut 12 abuts against the opposite side walls of the receiving cavity 1111, thereby limiting the nut 12 and ensuring that the nut 12 can only slide along the length direction of the vehicle.

[0070] like Figure 3 , Figure 8 and Figure 9 As shown, in some embodiments, the top edge module 30 is provided with a second through hole 3121; the second mounting part 112 is provided with a downward-facing sliding groove 1121, and the groove opening of the sliding groove 1121 is provided with a stop portion on each of the two side walls; the lifting bracket module 10 also includes a second screw connector 14, which is disposed in the sliding groove 1121 and is restricted from disengaging from the sliding groove 1121 by the stop portion, and the second screw connector 14 passes through the second through hole 3121 to connect the second mounting part 112 and the top edge module 30.

[0071] The side-top module 30 has a second through hole 3121 on the side facing the center of the vehicle. The bottom of the second mounting part 112 has a groove 1121, and a stop is provided at the opening of the groove 1121, making the groove 1121 T-shaped. The second screw connector 14 is configured as a bolt, the end of which is engaged in the groove 1121, allowing the bolt to slide along the length of the vehicle. The stop prevents the bolt from disengaging from the groove 1121. The bolt passes through the second through hole 3121 to connect the second mounting part 112 and the side-top module 30. This configuration allows for adjustment of the bolt position to accommodate manufacturing errors and improves assembly efficiency.

[0072] Since the side-top module 30 extends along the length of the vehicle and has a relatively long overall length, to ensure installation strength, the side-top module 30 is provided with multiple second through holes 3121, which are spaced apart along the length of the vehicle. Correspondingly, multiple lifting brackets 11 and second screw connectors 14 are provided, with at least one second screw connector 14 on each lifting bracket 11, and each second screw connector 14 corresponds one-to-one with a second through hole 3121, so as to install the side-top module 30 on multiple lifting brackets 11. This arrangement improves the overall installation strength of the side-top module 30.

[0073] In some embodiments, multiple lifting brackets 11 are provided, and the multiple lifting brackets 11 are arranged at intervals along the length direction of the vehicle. Since the lifting brackets 11 are connected to the crossbeams in the center roof module 20, and the crossbeams in the center roof module 20 are used not only for lifting the center roof but also for installing the handrails, in order to accommodate the two crossbeam cross sections of the center roof module 20, the lifting brackets 11 include a first lifting bracket and a second lifting bracket. The first lifting bracket and the second lifting bracket have the same structure. The length of the first lifting bracket is 160mm, and the length of the second lifting bracket is 110mm. The first lifting bracket and the second lifting bracket are arranged alternately. The first lifting bracket is connected to the crossbeam where the handrail mounting seat 25 is installed, and the second lifting bracket is connected to the remaining crossbeams.

[0074] like Figure 2 As shown, in some embodiments, the hanger module 10 further includes a wire groove 15, which extends along the length of the vehicle and is located on the hanger 11, between the first mounting portion 111 and the second mounting portion 112.

[0075] Since the equipment in the top passenger compartment is mostly electronic, it requires electrical connection via wiring harnesses during use. Therefore, a wiring trough 15 is also provided. The opening of the wiring trough 15 faces upward, and its overall shape is U-shaped. The wiring trough 15 extends along the length of the vehicle and is installed on multiple lifting brackets 11, located between the first mounting part 111 and the second mounting part 112. This arrangement avoids interference with the first mounting part 111 and the second mounting part 112. During assembly, the wiring trough 15 and the multiple lifting brackets 11 are installed on the auxiliary line. After assembly, the wiring trough 15 and the lifting brackets 11 are hoisted as a whole. The wiring harnesses in the wiring trough 15 are arranged and fixed on the auxiliary line. The wiring harnesses connecting to the electronic equipment and electrical cabinets have their connectors prefabricated under the vehicle. After the electrical cabinets, the middle roof module 20, and the side roof module 30 are installed, the plugs of the electrical components on the modules can be directly plugged into the connectors on the wiring trough 15. By setting up the wiring trough 15, the wiring harness layout can be standardized and pre-connected, reducing wiring harness operations in the main workshop. The cable tray 15 extends along the length of the vehicle, providing a unified cable tray channel for the center roof module 20 and the side roof module 30. This ensures the continuity of the cable tray layout, improves the efficiency of cable tray layout, reduces maintenance difficulty, and reduces the risk of failure caused by messy cable trays.

[0076] like Figures 5 to 6 As shown, in some embodiments, the center roof module 20 includes multiple sub-modules arranged sequentially along the length of the vehicle. Each sub-module includes a connecting beam 21, an air duct 22, a center roof plate 23, a first lighting component 24, and an armrest mounting base 25. The connecting beam 21 is connected to the hanging bracket module 10. The air duct 22 is located on the upper side of the connecting beam 21, and the center roof plate 23 is located on the lower side of the connecting beam 21. The center roof plate 23 has ventilation openings corresponding to the air outlets of the air duct 22. The first lighting component 24 is located on the center roof plate 23 and faces downwards. The armrest mounting base 25 is located on the connecting beam 21 and extends downwards through the center roof plate 23.

[0077] like Figure 5 , Figure 6 , Figure 10 and Figure 11As shown, the center roof module 20 extends along the length of the vehicle and has a relatively long overall length. For ease of assembly, the center roof module 20 is divided into multiple sub-modules, which are arranged sequentially along the length of the vehicle, and each sub-module is connected to a mounting bracket 11. Connecting beams 21 correspond one-to-one with mounting brackets 11, with both ends of the connecting beam 21 corresponding to the mounting brackets 11 of two mounting bracket modules 10. First through holes 211 are respectively provided at both ends of the connecting beam 21. The connecting beam 21 is connected to the nut 12 on the first mounting part 111 via a first screw connector 13 to achieve installation and fixation of the connecting beam 21. Air ducts 22 are mounted on the upper side of the connecting beams 21, and multiple air ducts 22 are sequentially connected to form a complete ventilation channel. A center roof plate 23 is installed on the lower side of the connecting beams 21, and the center roof plate 23 has ventilation openings to allow air from the air ducts 22 to enter the vehicle interior through the ventilation openings. The first lighting assembly 24 is installed on the center roof plate 23 for illuminating the vehicle interior. The upper end of the handrail mounting base 25 is mounted on the connecting beam 21, and the lower end of the handrail mounting base 25 extends downward through the central roof plate 23 for handrail installation. The central roof module 20 has ventilation, lighting, and passenger interface functions, and can also be equipped with a camera. In specific assembly, the sub-modules are first assembled on the auxiliary line, and then the sub-modules are installed sequentially on the vehicle.

[0078] Specifically, based on the existing design and roof panel segmentation scheme, and considering the vehicle length and module weight, there are seven sub-modules, each with a length of 2848mm, and the gap between two adjacent middle roof panels 23 is 8~15mm.

[0079] In some embodiments, the top plate 23 is a perforated aluminum plate, and the holes thereon constitute ventilation openings.

[0080] like Figure 10 As shown, in some embodiments, the connecting beam 21 includes a first connecting beam and a second connecting beam. The cross-sectional area of ​​the first connecting beam is larger than that of the second connecting beam, and the upper end of the handrail mounting base 25 is mounted on the first connecting beam. Both ends of the first connecting beam are connected to a first lifting bracket, and both ends of the second connecting beam are connected to a second lifting bracket. Because the connecting beam 21 connected to the handrail mounting base 25 requires high strength, the cross-sectional area of ​​the first connecting beam is larger than that of the second connecting beam. The second connecting beam, used to support the connection between the air duct 22 and the central top plate 23, does not require much strength and can have a smaller cross-sectional area. This maximizes the top-mounting function and lightweight design.

[0081] In some embodiments, each submodule has multiple connecting beams 21, and the multiple connecting beams 21 are spaced apart along the length direction of the vehicle.

[0082] Specifically, there is no limit to the number of first connecting beams and second connecting beams within each submodule. The module can consist entirely of first connecting beams, entirely of second connecting beams, or simultaneously contain both first and second connecting beams; the configuration can be determined based on the actual situation.

[0083] like Figure 12 As shown, in some embodiments, the upper side of the top plate 23 is provided with a longitudinal reinforcing rib 231, and the longitudinal reinforcing rib 231 has a downward-facing groove 232. The groove 232 is adapted to the first lighting component 24, and the first lighting component 24 is installed in the groove 232. This arrangement provides a mounting base for the first lighting component 24, and the longitudinal reinforcing rib 231 can also enhance the strength of the top plate 23.

[0084] In some embodiments, the upper side of the top plate 23 is further provided with transverse reinforcing ribs. The rigidity of the top plate 23 can be enhanced by providing transverse reinforcing ribs.

[0085] In some embodiments, the side of the air duct 22 is provided with a corner bracket, and the upper side of the connecting beam 21 is provided with a threaded sleeve. The corner bracket is connected to the threaded sleeve on the connecting beam 21 by bolts.

[0086] like Figures 13 to 14 As shown, in some embodiments, the side-top module 30 includes a side-top plate 31, a display device, and a second lighting component 32. One side of the side-top plate 31 is connected to the hanging bracket module 10, and the other side of the side-top plate 31 is used to connect to the side of the vehicle. The side-top plate 31 is provided with a first mounting hole 311, and the display device is installed in the first mounting hole 311. The second lighting component 32 is located inside the side-top plate 31 and is positioned towards the center-top module 20.

[0087] The side top plate 31 has a bent connecting portion 312 near the lifting bracket 11. The connecting portion 312 is Z-shaped, and a second through hole 3121 is located at one end of the connecting portion 312. The connecting portion 312 is connected to the second mounting portion 112 via a second screw connector 14. The side top plate 31 has a first mounting hole 311 for mounting display devices (such as dynamic maps, cameras, etc.). The second lighting component 32 is located at the connecting portion 312 and faces the center top module 20, providing auxiliary lighting. During assembly, the side top module 30 can be pre-installed on the auxiliary line with the display devices and the second lighting component 32, and then hoisted to the vehicle roof as a whole, finally achieving a quick connection with bolts. The pre-installation process improves installation efficiency and reduces errors caused by manual operation.

[0088] In some embodiments, the side ceiling module 30 further includes a loudspeaker, a smoke detector, a temperature sensor, and a passenger compartment noise detection device, all of which are mounted on the side ceiling panel 31.

[0089] like Figures 14 to 15 As shown, in some embodiments, the vehicle roof structure also includes a decorative panel 40, which is connected to the center roof module 20 and the side roof module 30 respectively. The decorative panel 40 is located below the hanging bracket module 10 and is used to cover the hanging bracket module 10.

[0090] Two decorative panels 40 are provided, each corresponding to one of the two mounting bracket modules 10. The decorative panels 40 extend along the length of the vehicle, and their two sides are connected to the center roof panel 23 and the side roof panel 31, respectively, and are located below the mounting bracket modules 10. This arrangement avoids exposing the mounting bracket modules 10 and improves the aesthetics of the roof structure.

[0091] like Figures 14 to 15 As shown, in some embodiments, the decorative panel 40 is plugged into the central top module 20, and the decorative panel 40 is connected to the side top module 30 via a third screw connector 43.

[0092] One side of the center roof panel 23 is bent downwards and hooked back to form a slot 233 with an opening facing the center of the vehicle. The upper side of the decorative panel 40 facing the center roof panel 23 has a plug-in part 41, and the end of the plug-in part 41 is bent towards the side of the vehicle to form a plug-in section 411, which is inserted into the slot 233. The side of the decorative panel 40 near the side roof panel 31 is bent downwards to form a mounting section 42. The inclination angle of the mounting section 42 is the same as that of the connecting part 312. The mounting section 42 has a threaded hole 421 and abuts against the connecting part 312. The connecting part 312 has a through hole corresponding to the threaded hole 421. The third screw connector 43 is configured as a screw, and the mounting section 42 is connected to the connecting part 312 through the screw. The decorative panel 40 is inserted into the central top plate 23 on one side and bolted to the side top plate 31 on the other side. The insertion of the decorative panel 40 into the central top plate 23 has been optimized from the original insertion from the outside to the middle to insertion from the middle to the outside, and a 5mm adjustment allowance is left at the insertion point. With this setting, the installation is convenient. When removing the central top plate 23, only the decorative panel 40 needs to be removed, and the side top module 30 no longer needs to be removed.
