[0002] To enhance the passenger experience, we have developed a self-sufficient and distinctive tour bus project. The design features include sleeper berths arranged longitudinally along the length of the bus. Passengers can enjoy the scenery through windows located next to the sleeper berths. The sleeper berths in the bus have at least two layers of double-window structures along the vertical direction, with each window corresponding to a sleeper berth, thereby improving the vehicle's quality and meeting passenger needs.

[0003] For bus bodies, the structural strength of the side wall panels is relatively low. After windows are opened on the side wall panels, the structural strength and rigidity of the side wall panels, as well as the load-bearing capacity of the vehicle body structure, are affected, posing safety hazards such as side wall panel deformation. Summary of the Invention

[0010] In some embodiments of this application, the fixed bending portion is provided with a plurality of fixing holes at intervals, and the upright beam is detachably connected to the side wall plate by fasteners.

[0011] In some embodiments of this application, along the thickness direction of the side wall panel, the height of the crossbeam is less than the height of the reinforcing upright, the clearance is formed on the reinforcing upright, and the crossbeam passes through the reinforcing upright from the clearance.

[0012] In some embodiments of this application, a weight-reducing cavity is formed between the crossbeam and the side wall panel, and welded bends parallel to the side wall panel are formed on both sides of the crossbeam, and the crossbeam is fixed to the side wall panel by the welded bends.

[0013] The design of the weight-reducing transverse cavity is similar to that of the weight-reducing longitudinal cavity, aiming to minimize the weight of the side wall panels while improving their structural strength.

[0014] In some embodiments of this application, an upper beam is provided on the upper side of the first window. The upper beam is L-shaped and includes an upper horizontal part and a lower vertical part arranged at an angle. The size of the upper horizontal part is smaller than the clearance opening, and the lower vertical part is fixed to the side wall panel.

[0015] In some embodiments of this application, a reinforcing beam is further provided below the upper beam, the top of the reinforcing beam is connected to the lower side of the upper horizontal part, the lower end of the reinforcing beam is welded to the side wall plate, and a reinforcing cavity is formed between the reinforcing beam, the upper beam and the side wall plate.

Vertical beams are provided on the left and right sides of the intermediate window, and horizontal beams are provided on the top and bottom sides of the intermediate window.

[0017] In another aspect, the present invention also proposes a railway passenger car, which includes the railway passenger car side wall structure involved in any of the above claims; wherein, the railway passenger car has a carriage formed by a base, a roof and the side wall panels.

[0018] Compared with the prior art, the advantages and positive effects of the present invention are: The railway passenger car side wall structure involved in this application includes at least two windows arranged vertically on each set of window components on the side wall panel to accommodate berths of different heights. In order to ensure the structural strength of the side wall panel, horizontal beams and vertical beams are provided on the side wall panel. The horizontal beams and vertical beams are provided at least on the periphery of the window to ensure the structural strength of the window position. The clearance on the horizontal beams or vertical beams can form a "well"-shaped structure at the connection between the horizontal beams and vertical beams, so that the connection between the vertical beams and horizontal beams has good fatigue resistance and safety performance.

[0028] In one aspect, the present invention provides a railway passenger car side wall structure and a railway passenger car, wherein the railway passenger car has a carriage formed by a base, a roof and side wall panels 100.

[0029] Specifically, the base is located at the bottom of the carriage, the roof is located at the top of the carriage, and the side wall panels 100 are located on both sides of the carriage.

[0030] For some special tourist bus projects, in order to enhance the design features, sleeper berths are arranged longitudinally along the length of the carriage.

[0031] Specifically, the side wall panels 100 near both sides are equipped with sleeping berths, which include at least an upper berth and a lower berth arranged one above the other, forming a corridor between the upper and lower berths on both sides.

[0032] refer to Figure 1 In order to ensure the passenger's riding experience and facilitate the passenger's enjoyment of the outside scenery, the side wall structure designed in this application is provided with a window component 110 on the side wall panel 100.

[0033] Multiple sets of window components 110 are arranged at intervals along the length of the vehicle body, and each window component 110 includes at least two windows arranged vertically.

[0034] In other words, the form component 110 includes two windows arranged vertically, or the form component 110 includes two or more windows arranged vertically, with gaps between adjacent windows.

[0035] The windows correspond one-to-one with the berths, meaning each berth has its own window.

[0036] When the sleeper includes an upper berth and a lower berth, the form component 110 includes two windows arranged vertically, with the upper berth corresponding to the upper window and the lower berth corresponding to the lower window.

[0037] When the sleeper berth includes an upper berth, a middle berth, and a lower berth, the form component 110 includes three windows: upper, middle, and lower. The upper berth corresponds to the position of the top window, the middle berth corresponds to the position of the middle window, and the lower berth corresponds to the position of the bottom window.

[0038] refer to Figure 2 , Figure 3 The side wall structure includes a side wall panel 100, a crossbeam 200, and a vertical beam 300. The crossbeam 200 is horizontally arranged along the length of the side wall panel 100 on the side of the side wall panel 100 away from the interior of the vehicle body. At least one of the upper and lower sides of each window is provided with a crossbeam 200.

[0039] The upright beam 300 is vertically installed along the height direction of the side wall panel 100 on the side of the side wall panel 100 away from the interior of the vehicle body, and at least one of the left and right sides of each window is provided with the upright beam 300.

[0040] For ease of understanding, the side of the side wall panel 100 closest to the inside of the carriage is defined as the inner wall, and the side away from the inside of the carriage is defined as the outer wall.

[0041] Both the horizontal beam 200 and the vertical beam 300 are installed on the outer wall of the side wall panel 100.

[0042] One of the crossbeams 200 and the vertical beams 300 is provided with a clearance opening 311, and the other crossbeam 200 and the vertical beam 300 pass through the clearance opening 311.

[0043] The crossbeam 200 and the vertical beam 300 are welded together to form a "well" shaped structure, which gives the structure good fatigue resistance and safety performance.

[0044] In some embodiments of this application, the window includes a first window 111 and a second window 112. The first window 111 is located above the second window 112. A crossbeam 200 is provided on the lower side of the first window 111, and crossbeams 200 are provided on both the upper and lower sides of the second window 112.

[0045] The first window 111 corresponds to the upper bunk, and the second window 112 corresponds to the lower bunk. The crossbeam 200 is used to ensure the structural strength of the side wall panel 100 in the thickness direction and to prevent deformation.

[0046] Taking a window including a first window 111 and a second window 112 arranged vertically as an example, upright beams 300 are respectively provided on the left and right sides of the first window 111 and the second window 112. The upright beams 300 are used to ensure the vertical structural strength of the first window 111 and the second window 112 and to prevent the windows and side wall panels 100 from deforming.

[0047] Combination Figure 7 In some embodiments of this application, the upright beam 300 includes a U-shaped reinforcing upright portion 310 and fixed bending portions 320 formed on both sides of the reinforcing upright portion 310.

[0048] That is, the cross-sectional shape of the upright beam 300 is hat-shaped, and a weight-reducing longitudinal cavity 330 is formed between the reinforcing upright part 310 and the side wall plate 100. The weight-reducing longitudinal cavity 330 helps to reduce the weight of the entire side wall plate 100.

[0049] The fixed bending part 320 is parallel to the side wall panel 100, and the upright beam 300 is fixed to the side wall panel 100 through the fixed bending part 320.

[0050] The design of the U-shaped reinforced upright 310 improves the structural strength of the side wall panel 100 without increasing its weight excessively.

[0051] The fixed bending part 320 and the reinforcing upright part 310 are integrally formed, specifically, by bending the sheet metal structure.

[0052] The fixed bending part 320 and the side wall panel 100 are connected and fixed by fasteners or welding.

[0053] In some embodiments of this application, the fixed bending portion 320 is provided with a plurality of fixing holes at intervals, and the upright beam 300 is detachably connected to the side wall plate 100 by fasteners.

[0054] Since the side wall panel 100 itself is relatively thin, in order to facilitate connection and fixation, preferably, the fixing bending part 320 is fixed to the outer wall of the side wall panel 100 by spot welding at the fixing hole position, so as to realize the connection and fixation of the side wall panel 100 and the upright beam 300.

[0055] After the vertical beam 300 is installed, the horizontal beam 200 is then fixed to the side wall panel 100 and the vertical beam 300.

[0056] In some embodiments of this application, along the thickness direction of the side wall panel 100, the height of the crossbeam 200 is less than the height of the reinforcing upright 310, the clearance opening 311 is formed on the reinforcing upright 310, and the crossbeam 200 passes through the reinforcing upright 310 from the clearance opening 311.

[0057] Combination Figure 5Specifically, the clearance opening 311 is formed on two end faces of the reinforcing upright 310 that are perpendicular to the side wall panel 100. The clearance opening 311 passes through the reinforcing upright 310 and is used for the crossbeam 200 to pass through.

[0058] Combination Figure 6 , Figure 8 In some embodiments of this application, a weight-reducing transverse cavity 220 is formed between the crossbeam 200 and the side wall plate 100, and welded bends 210 parallel to the side wall plate 100 are formed on both sides of the crossbeam 200, and the crossbeam 200 is fixed to the side wall plate 100 by the welded bends 210.

[0059] The design of the weight-reducing transverse cavity 220 is similar to that of the weight-reducing longitudinal cavity 330. Under the premise of improving the structural strength of the side wall panel 100, the weight of the side wall panel 100 is reduced as much as possible.

[0060] The clearance openings 311 are arranged at intervals along the length of the upright beam 300. Specifically, clearance openings 311 are provided at corresponding heights on the upper and lower sides of the first window 111 and the second window 112. The clearance openings 311 at different heights correspond to different crossbeams 200, so that crossbeams 200 are provided in at least part of the clearance openings 311 on the upper and lower sides of the first window 111 and the second window 112.

[0061] When assembling the side wall structure, first set the vertical beams 300 at intervals on the left and right sides of each window, and then pass the horizontal beams 200 through the corresponding clearance openings 311 of different vertical beams 300 and fix them to the vertical beams 300 and the side wall panels 100 by welding.

[0062] To facilitate the fixing of the crossbeam 200 to other positions and the side wall panel 100, a clearance opening 311 is designed to be set at the bottom of the reinforcing upright 310 near the side wall panel 100, so as to reduce the gap between the side wall panel 100 and the crossbeam 200. Since the thickness of the fixed bending part 320 is small, the crossbeam 200 is fixed to the side wall panel 100 by welding in addition to being fixed to the clearance opening 311.

[0063] refer to Figure 4 , Figure 5 , Figure 8 The upper beam 400 is L-shaped and includes an upper horizontal part 410 with a reinforcing bend 510 and a lower vertical part 420 arranged at an angle. The size of the upper horizontal part 410 with the reinforcing bend 510 is smaller than the clearance opening 311, and the lower vertical part 420 is fixed to the side wall panel 100.

[0064] The lower support 420 is fixed to the upright beam 300 and the side wall panel 100 by welding. Specifically, the lower support 420 is connected to the upright beam 300 by welding to the periphery of the clearance opening 311 or to the fixed bending part 320 of the upright beam 300.

[0065] Since the thickness of the fixed bending part 320 is relatively thin, other positions of the lower upright part 420 can also be further connected and fixed to the side wall panel 100 by welding.

[0066] In some embodiments, since the top of the side wall panel 100 is fixedly connected to the ceiling, in order to achieve the purpose of connecting the foundation, an upper beam 400 is designed to be provided on the upper side of the first window 111, and the upper beam 400 passes through the clearance opening 311 of the corresponding vertical beam 300 on the upper side of the first window 111.

[0067] After the horizontal beam 200 and the vertical beam 300 are welded, the upper beam 400 is passed through the clearance opening 311 on the upper side of the first window 111 to achieve the connection and fixation between the upper beam 400 and the side wall panel 100.

[0068] The upper beam 400 is used to connect and fix the side wall panel 100 to the ceiling. The side wall panel 100 is higher than the upper beam 400 by a certain height so that the sealing between the side wall panel 100 and the ceiling is better when it is connected and fixed to the ceiling, thereby improving the sealing effect of the carriage.

[0069] In some embodiments of this application, a reinforcing beam 500 is provided below the upper beam 400. The top of the reinforcing beam 500 is connected to the lower side of the reinforcing bend 510 of the upper horizontal part 410, and the lower end of the reinforcing beam 500 is welded to the side wall plate 100. A reinforcing cavity 520 is formed between the reinforcing beam 500, the upper beam 400, and the side wall plate 100.

[0070] Specifically, the bottom of the reinforcing beam 500 has a reinforcing bend 510, which extends toward the side wall panel 100. The bottom of the reinforcing bend 510 is parallel to the side wall panel 100 and is fixed to the upright beam 300 and the side wall panel 100 by welding.

[0071] In some embodiments of this application, a longitudinally arranged intermediate window 120 is also provided on the side wall panel 100. The intermediate window 120 is located on one side of the window assembly 110 or between adjacent window assemblies 110. Vertical beams 300 are provided on the left and right sides of the intermediate window 120, and horizontal beams 200 are provided on the upper and lower sides of the intermediate window 120.

[0072] The horizontal beams 200 on the top and bottom sides of the middle window 120 are shared with the first window 111 and the second window 112. Specifically, the horizontal beam 200 on the bottom side of the first window 111 extends to the top side of the middle window 120, and the horizontal beam 200 on the bottom side of the second window 112 extends to the bottom side of the middle window 120.

[0073] The beam 200 on the upper side of the second window 112 is cut into multiple segments by the middle window 120. The reasonable arrangement ensures the continuity of the skeleton and improves the strength of the side wall.

[0074] In addition to the perimeter of the window, horizontal beams 200 and vertical beams 300 can also be installed at other locations on the side wall panel 100 to further improve the structural strength of the side wall panel 100.

[0075] The railway passenger car side wall structure involved in this application includes at least two windows arranged vertically on each set of window components 110 on the side wall panel 100, in order to accommodate berths of different heights and meet the lighting and field of vision requirements of longitudinal berths.

[0076] To ensure the structural strength of the side wall panel 100, a horizontal beam 200 and a vertical beam 300 are provided on the side wall panel 100. The horizontal beam 200 and the vertical beam 300 are provided at least around the window to ensure the structural strength of the window position. The clearance opening 311 on the horizontal beam 200 or the vertical beam can form a "well"-shaped structure at the connection between the horizontal beam 200 and the vertical beam, so that the connection between the vertical beam and the horizontal beam 200 has good fatigue resistance and safety performance.

[0077] In other embodiments, in order to improve the corrosion resistance of the sidewall structure and enable it to be used in humid, hot, rainy, and coastal corrosive environments, the sidewall panel 100 is designed to be made of weather-resistant structural steel, and corrosion-resistant structural design and coating sealing design are carried out to comprehensively improve the corrosion resistance of the sidewall.

[0078] By selecting corrosion-resistant materials for the side walls, designing corrosion-resistant structures, and implementing coating and sealing designs, the corrosion resistance of the vehicle body can be improved, meeting the needs of vehicles to be used in humid, hot, rainy, and coastal corrosive environments.

[0079] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
