[0057] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0058] like Figure 1 As shown, this utility model provides a rail transit sightseeing car, including several glass windows 100 and a side wall structure 200; the side wall structure 200 includes two first structural members 210 and several second structural members 220, the first structural members 210 and the second structural members 220 are independent profile structures, the first structural members 210 are arranged parallel along the X direction, and the second structural members 220 are parallel to each other and vertically supported between the first structural members 210 to separate several mounting frames; the glass windows 100 are disposed in the mounting frames and are respectively connected to the first structural members 210 and the second structural members 220; the upper ends of the second structural members 220 and the glass windows 100 are continuous arc shapes.

[0059] Traditional passenger car window frames involve opening windows in a continuous profile on the side of the vehicle, with the window glass bonded to the cut profile wall. Considering structural strength and operational safety, the windows are spaced far apart, typically arranged horizontally along the length of the passenger car wall. This invention provides a rail transit sightseeing car that uses independent first structural members 210 and second structural members 220 to construct the side wall structure 200. The second structural members 220 are parallel and vertically supported between the upper and lower first structural members 210. Adjacent second structural members 220 and the upper and lower first structural members 210 form the mounting frame for the glass window 100. The supporting strength of the aforementioned side wall structure 200 is higher than that of a direct... The window openings in the profile are large, and the spacing between the glass windows 100 is determined by the width of the second structural member 220. Different structures or materials and different support strengths of the first structural member 210 and the second structural member 220 can be selected according to the installation spacing requirements. The distance between the first structural members 210 is increased, and the narrower second structural member 220 is selected, thereby increasing the area of ​​the glass windows 100 and making the field of vision wider, so that passengers can have a better travel experience. At the same time, the upper end of the second structural member 220 and the glass windows 100 are continuous arc shapes. Through the above arc shape, the glass windows 100 are extended upward to cover the shoulder position of the carriage, further increasing the height of the glass windows 100 and providing a better field of vision.

[0060] like Figure 2 , Figure 3As shown, the first structural member 210 is an L-shaped three-cavity profile, and the first structural member 210 includes a first support cavity 211 located at the end of the L-shape; the second structural member 220 is a straight four-cavity profile, and the second structural member 220 includes second support cavities 221 symmetrically arranged on both sides of the H-shaped structure; the glass window 100 is bonded to the first support cavity 211 and the second support cavity 221 respectively. The side wall structure 200 of the compartment, which is formed by selecting an L-shaped three-cavity profile as the first structural member 210 and a straight four-cavity profile as the second structural member 220, can meet the support strength requirements of the large-view glass window 100 provided by this utility model. At the same time, when the first support cavity 211 of the first structural member 210 located at the L-shaped end and the second support cavity 221 of the second structural member 220 symmetrically arranged on both sides of the H-shaped structure, the first structural member 210 and the second structural member 220 together form the mounting frame of the glass window 100, an inwardly recessed mounting space is formed on the mounting frame for placing and installing the glass window 100. The glass window 100 is placed in the mounting space formed by the first structural member 210 and the second structural member 220 and fixed by adhesive connection, so that the outer facade of the compartment remains flat. In addition, the L-shaped configuration of the first structural member 210 and the straight configuration of the second structural member 220 form a flat surface on the inner side of the carriage. Unlike traditional carriages where the inner side needs to be covered by an interior cover, the carriage provided by this utility model does not have separate decorative parts on the inner side of the carriage side wall structure. Instead, a decorative layer such as decorative paint is directly applied to the surfaces of the first structural member 210 and the second structural member 220 facing the inner side of the carriage. This avoids the interior cover from encroaching on the window space, thereby further increasing the visible area of ​​the window, while saving material costs and installation procedures.

[0061] Specifically, in some embodiments provided by this utility model, the glass windows 100 are spaced 250mm-300mm apart; the length of the glass windows 100 along the X direction is 1300mm-1400mm; the length of the glass windows 100 along the Y direction is 1750mm-1800mm; preferably, such as Figure 4 As shown, the glass windows 100 are spaced 250mm apart, and the dimensions of each glass window 100 are 1360 mm × 1780 mm. The length of each glass window 100 is curved along its top, and the bottom of each glass window 100 is 700mm from the carriage floor. In contrast, traditional carriage windows use flat glass. The standard size of a Chinese subway window is 1436mm × 966 mm, and the size of a high-speed train window is 1490mm × 790 mm. Furthermore, the spacing between these windows is larger; the standard spacing for Chinese subway windows is 3210 mm or 3110 mm, while the spacing for high-speed train windows is approximately 500 mm. The bottom of each window is generally about 900mm from the carriage floor. Compared to traditional ordinary carriage windows, the rail transit sightseeing carriage provided by this invention offers a wider field of vision.

[0062] In some embodiments provided by this utility model, the glass window 100 includes a dimming glass assembly, such as... Figure 5 As shown, the dimming glass assembly includes a first glass layer 110, a first PVB layer 120, a flexible SPD dimming layer 130, a second PVB layer 140, and a second glass layer 150 stacked sequentially from the outside in. In this embodiment, the dimming glass assembly can change its light transmittance according to the intensity of external light, ensuring the passenger's sightline in different weather conditions. Specifically, the dimming glass assembly is a laminated electrochromic glass, which consists of an outer glass, a PVB film, an SPD dimming layer, and an inner glass. SPD (Suspended Particle Device) is a dimming crystal technology containing microparticles. These microparticles change their arrangement under the influence of an electric field, thereby changing the transparency of the glass. The transmittance of the SPD dimming film can be infinitely adjusted between 0.5% and 50%. The electrode 131 of the SPD dimming film is located in the black edge area around the glass. The external cable 133 is connected to the electrode 131 by soldering. It can change its transmittance according to the intensity of external light, filtering out excessive light and adapting to the sightseeing needs under different weather conditions. PVB (PolyVinyl Butyral Film) is a semi-transparent film with good adhesion to glass. It has the characteristics of transparency, heat resistance, cold resistance, and high mechanical strength, making it an excellent adhesive material for manufacturing laminated glass. The SPD dimming layer has a flexible structure and can be used with the PVB film to achieve a curved shape to adapt to the arc shape of the upper part of the inner and outer glass layers. The dimming glass assembly uses curved glass to obtain a larger viewing area. The glass uses a chemical tempering process to obtain lower optical distortion parameters than physically tempered glass. The dimming glass assembly uses a PVB lamination process to laminate the dimming layer between the inner and outer glass layers. Compared with a hollow structure, it can obtain better overall rigidity performance at the same glass thickness.

[0063] like Figures 6-9As shown in some embodiments of this utility model, a rail transit sightseeing carriage disclosed in this utility model also includes a decorative component 300. The decorative component 300 is connected to the interior side wall of the carriage and located below the glass window 100. The decorative component 300 includes a base plate 310, a honeycomb panel 320, a decorative panel 330, and a frame 340. The base plate 310 and the honeycomb panel 320 are sequentially connected to the side wall. The decorative panel 330 is movably connected between the frame 340 and the honeycomb panel 320. The lower part of the frame 340 is detachably connected to the bottom. The bottom provides support and fixation, the honeycomb panel 320 reduces noise and provides heat insulation, the frame 340 connects to the periphery of the base plate 310, and the movable decorative panel 330 is fixedly sandwiched between the honeycomb panel 320 and the frame 340. The interior walls of the carriage are decorated with decorative components 300. The movable decorative panels 330 within these components can be flexibly replaced according to different travel routes. The theme of the decorative panels 330 can be changed at any time based on the scenic features and seasons of different travel routes, allowing for diverse and adaptable decoration of the carriage. For example, the decorative components 300 include an aluminum alloy base plate 310, an aluminum honeycomb pad, a PC decorative panel 330, and an aluminum profile frame 340. The aluminum alloy base plate 310 and the honeycomb pad are connected to the side wall with screws. The upper frame 340 is integral with the side frame 340 and is attached to the aluminum alloy base plate 310. The lower frame 340 is mechanically fastened to the base plate 310 through countersunk holes. The PC decorative panel 330 is located between the frame 340 and the honeycomb pad, clamped and fixed by both. When changing the theme, simply remove the lower frame 340 and replace the PC decorative panel 330.

[0064] like Figures 10-11 As shown, in some embodiments provided by this utility model, a rail transit sightseeing car disclosed by this utility model also includes a door curtain rod assembly 400. The door curtain rod assembly 400 includes a door curtain 410, a rod 420, and a semi-circular tube mounting component 430 corresponding to the rod 420. The semi-circular tube mounting component 430 is fixedly installed on the side wall of the car, the rod 420 is movably connected to the semi-circular tube mounting component 430, and the door curtain 410 is sleeved on the rod 420. In this embodiment, a curtain can be fixedly connected to the curtain rod assembly 400 on the side of the entrance door at the end of the carriage to increase the privacy of the carriage. Specifically, an aluminum semi-circular tube mounting part 430 is fixed on the side wall of the carriage to facilitate the installation of steel threaded sleeves, avoid installation errors, and facilitate the installation of the rod 420. The rod 420 is made of stainless steel. By setting countersunk holes on the rod 420, the use of gaskets can be reduced and the fastening screws can be hidden. The rod 420 is equipped with a limiting structure. In passenger operation mode, the curtain is pulled up and tied with the straps 450 on the side wall, making the entire carriage a whole. When needed, the curtain is unfolded and fixed by the counterweight block 460 at the bottom of the curtain 410 and the limiting block on the rod, so as to prevent the curtain 410 from shaking during the operation and when the door is opened and closed, thus ensuring the privacy of the carriage.

[0065] In some embodiments provided by this utility model, a rail transit sightseeing car disclosed in this utility model also includes a floor assembly 500, such as... Figure 12 As shown, the floor assembly 500 includes, from bottom to top, an insulation layer 510a, a sound-absorbing layer 510b, a main floor layer 520, and a decorative floor layer 530 laid on the floor of the carriage body. The floor assembly 500 also includes elastic shock-absorbing supports 540, which are spaced apart within the insulation layer 510a and the sound-absorbing layer 510b, and connected to the carriage body floor and the lower side of the main floor layer 520, respectively. This embodiment eliminates the traditional floor mounting beam at the bottom of the carriage body, using shock-absorbing supports to support the main floor layer 520 on the carriage floor. The insulation layer 510a and the sound-absorbing layer 510b fill the space between the main floor layer and the carriage floor, eliminating rigid connections while improving support elasticity, thus improving the vibration damping and sound insulation effects of the carriage and effectively ensuring the dynamic comfort of the carriage. Preferably, highly elastic foamed silicone rubber is used as the material for the shock-absorbing supports.

[0066] like Figures 13-14 As shown, in some embodiments provided by this utility model, the floor assembly 500 is further provided with a plurality of evenly arranged mounting slots 600 for mounting seats. The floor assembly 500 also includes a covering layer 560. The carriage has a first state and a second state. In the first state, the seats are mounted on the mounting slots 600 by mounting members 610 and 610. In the second state, the filling members 620 and 620 fill the mounting slots 600. The filling members 620 are filled with a filling pad and screws. The filling pad has a countersunk hole and is connected to the internal thread block of the mounting slot 600 with a matching countersunk screw to ensure that the pad is flat with the floor surface after filling. The covering layer 560 covers the floor decoration layer 530 to cover the mounting slots 600, and facilities are arranged on the covering layer 560. Figure 15 As shown, when carrying a large number of passengers, multiple rows of seats required by passengers are installed in the mounting slot 600 via connectors to provide high capacity. However, when the number of tour groups is small or a more comfortable and spacious seating area is needed, such as... Figure 16 As shown, the seats are removed, and a covering layer 560 is laid on the floor assembly 500 to make the ground a whole.
