Detailed Implementation

[0050] This invention discloses a double-decker rail vehicle, which addresses the problem of high maintenance costs due to the need to remove most of the interior components of the vehicle when the vehicle is flooded.

[0051] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0052] Please see Figure 1 , 8 9 and 10 Figure 1 This is a structural schematic diagram of a staircase assembly 1000 provided in an embodiment of this application; Figure 8 A structural schematic diagram of the partition wall assembly 2000 provided in the first orientation of this application; Figure 9 A structural schematic diagram of the partition wall assembly 2000 provided in the second position of this application; Figure 10 for Figure 9 A partially enlarged structural diagram.

[0053] In one specific embodiment, the double-decker rail vehicle provided in this application includes a staircase assembly 1000 and a partition assembly 2000. The staircase assembly 1000 is detachably connected to the vehicle body, for example, by means of connecting profiles, to facilitate assembly and disassembly. The staircase assembly 1000 includes a first-level staircase 100 and a second-level staircase 110 that are connected; the entrance end of the first-level staircase 100 is located at the bottom floor of the double-decker rail vehicle, and the two are detachably connected, which can be secured using threaded fasteners. The exit end of the second-level staircase 110 is located at the top floor 305 of the double-decker rail vehicle, and is also detachably connected. It is understood that if water enters the first-level staircase 100 and / or the second-level staircase 110 and flows into the floor, maintenance can be performed by disassembling the first-level staircase 100 and / or the second-level staircase 110 respectively.

[0054] The partition assembly 2000 is located at both ends of the stair assembly 1000 in the width direction. The partition assembly 2000, together with the vehicle body and the stair assembly 1000, forms a closed space that can be used to place electrical components or store items. The entrance end of the stair assembly 1000 is oriented towards the length direction of the double-decker rail vehicle; the partition assemblies are arranged along the width direction of the double-decker rail vehicle. Preferably, the partition assembly 2000 is located at both ends of the stair assembly 1000.

[0055] Compared with the prior art, the double-decker rail vehicle provided in this application has the following technical advantages:

[0056] The staircase assembly 1000 includes a first-level staircase 100 and a second-level staircase 110, with the first-level staircase 100 located on the bottom floor of the double-decker railcar and the second-level staircase 110 located on the top floor 305, thus connecting the top and bottom floors. The staircase assembly 1000 is detachably connected to the car body, and partition assemblies 2000 are located at both ends of the staircase assembly 1000 in the width direction, respectively detachably connected to the staircase assembly 1000 and / or the car body. This configuration allows for easy removal of the staircase assembly 1000 or partition assembly 2000 from the flooded area after water ingress, enabling repair and replacement based on the location of the flooding, simplifying maintenance operations and reducing maintenance costs.

[0057] The stair assembly 1000 also includes a stair wall panel 130 and a stair handrail 120. The stair wall panel 130 is detachably and fixedly connected to the first-floor staircase 100 and the second-floor staircase 110. Preferably, the stair wall panel 130 extends vertically from bottom to top to separate and protect the first-floor staircase 100 and the second-floor staircase 110. The stair handrail 120 corresponding to the first-floor staircase 100 is fixed to the bottom floor and partition assembly 2000 of the double-decker rail vehicle. The stair handrail 120 corresponding to the second-floor staircase 110 is fixed to the top of the stair wall panel 130 and surrounds the top edge of the stair wall panel 130 to provide support for passengers.

[0058] like Figure 2-7 As shown, Figure 2 A schematic diagram of the side structure of the stair assembly 1000 provided in an embodiment of this application; Figure 3 for Figure 2 A magnified schematic diagram of the structure at point A in the diagram; Figure 4 for Figure 2 A magnified schematic diagram of the structure at point D in the diagram; Figure 5 A cross-sectional structural schematic diagram of the second-floor staircase 110 provided in an embodiment of this application; Figure 6 for Figure 5 A magnified schematic diagram of the structure at point B in the diagram; Figure 7 for Figure 5 A magnified schematic diagram of the structure at point C.

[0059] For the installation of the stair assembly 1000 on the vehicle body, to facilitate disassembly and assembly, the stair assembly 1000 also includes a first entrance end mounting seat 101, a first exit end mounting seat 102, a second entrance end mounting seat 103, and a second exit end mounting seat 104. The first entrance end mounting seat 101 is located at the entrance end of the first floor stair 100 and extends outward along the first floor stair 100 to be fixed to the vehicle body welding mounting seat 301, preferably by threaded fasteners, specifically bolts, flat washers, spring washers, and nuts to fix the first entrance end mounting seat 101 to the vehicle body welding mounting seat 301. The first exit end mounting seat 102 is located at the exit end of the first floor stair 100 and extends outward along the first floor stair 100 to be fixed to the vehicle body welding mounting seat 302, and the fixing method is as described above. The second entrance mounting base 103 is installed at the entrance end of the second-floor staircase 110 and is embedded inside the second-floor staircase 110 and fixed to the vehicle body welding mounting base 303, thereby optimizing the entrance structure of the second-floor staircase 110 and facilitating the fixing of the second-floor staircase 110 and the vehicle body. Similarly, the fixing method of the second entrance mounting base 103 and the vehicle body welding mounting base 303 is set as described above. The second exit mounting base 104 is located at the exit end of the second-floor staircase 110 and extends outward along the second-floor staircase 110 to be fixed to the internal profile interface 304 of the vehicle body.

[0060] like Figure 17-20 As shown, Figure 17 A schematic diagram of the installation structure of the third staircase wall panel 133 provided in an embodiment of this application; Figure 18 An installation diagram of the first stair wall panel 131 and the second stair wall panel 132 provided in the embodiments of this application; Figure 19 A schematic diagram of the installation of the first staircase wall panel 131 and the top floor 305 provided in the embodiments of this application; Figure 20 A schematic diagram of the installation structure of the first staircase wall panel 131 and the second floor staircase 110 provided in the embodiments of this application;

[0061] Specifically, the stair wall panel 130 includes a first stair wall panel 131, a second stair wall panel 132, and a third stair wall panel 133. In the width direction of the stair assembly 1000, the first stair wall panel 131 is located between the first floor stair 100 and the second floor stair 110, serving to separate and protect the first floor stair 100 and the second floor stair 110. In the vertical direction of the stair assembly 1000, the first stair wall panel 131 extends upwards from the first floor stair 100 to protrude beyond the second floor stair 110. Preferably, the height by which the first floor stair 100 protrudes beyond the second floor stair 110 can be set according to design requirements to meet protection requirements.

[0062] To facilitate the installation of the first stair wall panel 131, the stair assembly 1000 also includes a stair wall panel mounting base 105. The stair wall panel mounting base 105 extends outward along the width direction of the stair assembly 1000. Preferably, the stair wall panel mounting base 105 is located in the upper middle part of the first stair 100 to support the first stair wall panel 131. The bottom of the first stair wall panel 131 is located above the stair wall panel mounting base 105 and is detachably connected to the stair wall panel mounting base 105. The two are connected by bolts, flat washers, spring washers, and nuts. The middle part is fixedly connected to the threaded sleeve embedded in the top floor 305 of the double-layer rail vehicle by threaded fasteners to fix the first stair wall panel 131 to the vehicle body. The side wall of the first stair wall panel 131 is fixedly connected to the second stair 110 by threaded fasteners, thereby fixing the first stair wall panel 131 at the top, middle, and bottom respectively to improve stability.

[0063] Meanwhile, to further improve the installation stability of the stair wall panel 130, a second stair wall panel 132 and a third stair wall panel 133 are provided, such as... Figure 15 As shown, the two ends of the second stair wall panel 132 are fixed to the first stair wall panel 131 and the third stair wall panel 133, respectively. Also a detachable connection, the end of the third stair wall panel 133 away from the second stair wall panel 132 is fixed to the partition assembly 2000. Connecting profiles 134 and clip nuts 135 are respectively provided between the second stair wall panel 132 and the first stair wall panel 131 and the third stair wall panel 133, and between the third stair wall panel 133 and the partition assembly 2000. Clip nuts 135 are pre-embedded in the connecting profiles 134 to allow movement in the width direction of the connecting profiles 134, adjusting the fixing position as needed, facilitating transportation and assembly, and making operation simpler and faster. The bottoms of the second stair wall panel 132 and the third stair wall panel 133 are fixed to the top floor 305 of the double-decker rail vehicle to further improve the stability of the stair wall panel 130.

[0064] In one embodiment, such as Figure 8 As shown, the partition assembly includes a first partition assembly 200 and / or a second partition assembly 210. The first partition assembly 200 is located on the side of the first floor staircase 100 away from the second floor staircase 110; the second partition assembly 210 is located on the side of the second floor staircase 110 away from the first floor staircase 100; it can be seen that the third staircase wall panel 133 is detachably fixedly connected to the first partition assembly 200.

[0065] The partition wall assembly is arranged along the width direction of the double-decker rail vehicle, thereby forming a cavity with the partition wall assembly and the side wall of the double-decker rail vehicle to accommodate an electrical cabinet and optimize the internal space of the double-decker rail vehicle. Specifically, the first partition wall assembly 200 and the side wall of the double-decker rail vehicle form a first cavity for installing the electrical cabinet. The second partition wall assembly 210 and the side wall of the double-decker rail vehicle form a second cavity for installing the electrical cabinet.

[0066] like Figure 11-16 , Figure 11 This is a schematic diagram of the installation structure of the first upper secondary partition wall 2031 and the top secondary frame 308 of this application; Figure 12 This is a schematic diagram of the installation structure of the first main partition wall 201 and the first auxiliary partition wall 203 in this application; Figure 13 This is a schematic diagram of the installation structure of the first inspection door 204 according to the first embodiment of this application; Figure 14 This is a schematic diagram of the installation structure of the first inspection door 204 according to the second embodiment of this application.

[0067] Due to the structural design of the overall staircase area, the interior space is small after the installation of electrical cabinets and air ducts, which increases the difficulty of installing the various parts of the partition wall and makes it inconvenient to directly fix them to the vehicle body. Therefore, the tops of the first partition wall assembly 200 and the second partition wall assembly 210 are respectively fixed to the secondary frame of the vehicle body roof. Specifically, the first partition wall assembly 200 includes a first main partition wall 201, a first secondary partition wall 203, and a first inspection door 204. The first main partition wall 201 is located near the side wall of the first floor staircase 100 and extends along the length of the double-decker rail vehicle; the bottom of the first main partition wall 201 is fixed to the vehicle body via a partition wall mounting seat 202, the top of the first main partition wall 201 is fixedly connected to the top secondary frame 308 of the double-decker rail vehicle, and the middle part of the first main partition wall 201 is fixed to the electrical cabinet frame via the partition wall mounting seat 202; the fixing method is a detachable connection, such as through threaded fasteners. The first main partition wall 201, the first auxiliary partition wall 203, the first inspection door 204, and the side walls of the double-decker railcar form a first accommodating cavity for placing electrical cabinets or storing other equipment.

[0068] The surrounding partition wall panels are assembled based on the first main partition wall 201. Due to the limited internal structure, the first main partition wall 201 provides fixing points for the surrounding partition wall panels, which are then fixed by threaded fasteners. Specifically, in the length direction of the double-decker rail vehicle, the first auxiliary partition wall 203 and the first inspection door 204 are located at both ends of the first main partition wall 201 and are detachably fixedly connected. This enables the assembly of the partition wall components, facilitating transportation and assembly, and making operation easier.

[0069] The first secondary partition wall 203 is fixedly connected to the first main partition wall 201 via a connecting profile 134. The first secondary partition wall 203 and the connecting profile 134 are fixed by a retaining nut 135 and threaded fasteners. The end wall of the first secondary partition wall 203 is opposite to the wall surface of the first main partition wall 201. The connecting profile 134 is an L-shaped profile, and the two walls of the L-shaped profile are respectively attached to the first secondary partition wall 203 and the first main partition wall 201 and fixed by threaded fasteners. Preferably, the first secondary partition wall 203 and the connecting profile 134 are fixed by a retaining nut 135 and threaded fasteners. The first secondary partition wall 203 is provided with a threaded hole, and the retaining nut 135 can be adjusted in position along the length of the connecting profile 134. The L-shaped profile is provided with a strip hole, and the retaining nut 135 can move on the strip hole so that it can be adjusted when there is an installation error in the first secondary partition wall 203, further improving the ease of operation.

[0070] Meanwhile, to improve the stability of the device, the first partition wall assembly 200 also includes a first gap-blocking profile 205, located at the connection between the first secondary partition wall 203 and the first main partition wall 201, that is, at the point where the end wall of the first secondary partition wall 203 is opposite to the wall surface of the first main partition wall 201. Figure 31 As shown, Figure 31 This is a structural schematic diagram of the first gap-blocking profile of this application; the first gap-blocking profile 205 includes a first L-shaped body 2051 and a first gap-blocking protrusion 2052. The short side of the first L-shaped body 2051 is attached to the outer wall of the first main partition wall 201, which is the wall surface near the stair assembly 1000. The long side of the first L-shaped body 2051 is attached to the outer wall of the first secondary partition wall 203, which is the wall surface facing away from the first access door 204; the first gap-blocking protrusion 2052... The first gap-blocking protrusion 2052 is fixed to the long side of the first L-shaped body 2051. The first gap-blocking protrusion 2052 and the first L-shaped body 2051 are integrally set. The first gap-blocking protrusion 2052 is located in the gap between the inner wall of the first main partition wall 201 and the end wall of the second secondary partition wall 212, and seals the gap. At the same time, in order to fix the first gap-blocking profile 205 and the first secondary partition wall 203, the long side of the first L-shaped body 2051 is provided with a first nylon hook and loop fastener 2053 for fixing to the first secondary partition wall 203.

[0071] In another embodiment, the first inspection door 204 has a hinge 2041 and a door lock assembly 2042 at both ends. One end of the first inspection door 204 is fixed to the mounting profile 3061 fixed to the vehicle body door pillar beam 306 via the hinge 2041; the other end of the first inspection door 204 can be fixed to the door frame profile lock pad 307 of the electrical cabinet via the door lock assembly 2042. The mounting profile 3061 is a T-shaped profile, with a strip-shaped threaded hole and a retaining nut 135 provided on one side wall. The strip-shaped threaded hole is arranged along the width direction of the first inspection door 204 to adjust the installation error between the first inspection door 204 and the vehicle body door pillar beam 306 through the strip-shaped threaded hole and the retaining nut 135, facilitating installation. The hinge 2041 is installed on the other side wall of the T-shaped profile, and a threaded sleeve is provided on this side wall to achieve installation and fixation with the hinge 2041.

[0072] The door lock assembly 2042 is fixed to the top of the inner wall of the first access door 204. When the door lock assembly 2042 is locked, the latch of the door lock assembly 2042 extends to contact the lock pad 307 of the door frame profile of the electrical cabinet to lock the first access door 204. The structure of the door lock assembly 2042 can be set with reference to the prior art, and will not be described in detail here.

[0073] In one embodiment, the first secondary partition 203 includes a first upper secondary partition 2031 and a first lower secondary partition 2032. The top of the first upper secondary partition 2031 is fixed to the top secondary frame 308 of the double-decker rail vehicle. Along the width of the stair assembly 1000, the ends of the first upper secondary partition 2031 are fixed to the first main partition 201 and the side wall of the double-decker rail vehicle, respectively. The bottom of the first upper secondary partition 2031 is fixed to the top floor 305 of the double-decker rail vehicle via a partition mounting seat 202. Specifically, the first upper secondary partition 2031 and the first main partition 201 are fixed using the connecting profile 134 and the retaining nut 135 described above. The first upper secondary partition 2031 and the side wall are fixed using mounting seats. The bottom of the first upper secondary partition 2031 is fixed to the top floor 305 via the partition mounting seat 202.

[0074] Similarly, the top of the first lower auxiliary partition wall 2032 and the bottom top plate of the double-decker rail vehicle, and the end of the first lower auxiliary partition wall 2032 and the side wall of the double-decker rail vehicle can also be connected by mounting brackets. The first lower auxiliary partition wall 2032 and the first main partition wall 201 are fixed by the connecting profile 134 and the clip nut 135 mentioned above, respectively.

[0075] As described above, the first secondary partition 203 is divided into a first upper secondary partition 2031 and a first lower secondary partition 2032, so that the assembly and the first main partition 201 form a frame, which facilitates disassembly, transportation and simplifies the installation operation.

[0076] Furthermore, to achieve the installation and fixation of the first inspection door 204 and simultaneously form the first accommodating cavity, the first partition assembly 200 also includes a first inspection door partition 206, located above the first inspection door 204 and fixed to the top secondary frame 308 of the double-decker rail vehicle; in the width direction of the double-decker rail vehicle, both ends of the first inspection door partition 206 are fixed to the first main partition 201 and the side wall of the double-decker rail vehicle, respectively. It can be understood that the first accommodating cavity is ultimately formed by the first main partition 201, the first secondary partition 203, the first inspection door 204, and the first inspection door partition 206.

[0077] In one embodiment, the second partition assembly 210 includes a second main partition 211, a second secondary partition 212, and a second access door 213. The second main partition 211 is located near the side wall of the second-floor staircase 110. The top of the second main partition 211 is fixedly connected to the top secondary frame 308 of the double-decker rail vehicle, preferably a detachable connection, such as using threaded fasteners. The bottom of the second main partition 211 is fixed to the side wall of the second-floor staircase 110 via a partition mounting bracket 202, secured with bolts, flat washers, and spring washers. A pre-embedded mounting thread sleeve is provided for fitment. Preferably, the middle portion of the second main partition 211 is fixed to the electrical cabinet frame via the partition mounting bracket 202 to improve the stability of the device.

[0078] Meanwhile, along the length of the double-decker rail vehicle, the second auxiliary partition 212 and the second inspection door 213 are located at both ends of the second main partition 211, and the second main partition 211, the second auxiliary partition 212, the second inspection door 213, and the side walls of the double-decker rail vehicle form a second accommodating cavity. The fixing of the second auxiliary partition 212, the second main partition 211, and the second inspection door 213 can be referenced to the first main partition 201, the first auxiliary partition 203, and the first inspection door 204.

[0087] like Figures 21-30 As shown, Figure 21 This is a structural schematic diagram of the staircase cover assembly 230 provided in an embodiment of this application; Figure 22 A schematic diagram of the installation structure of the staircase cover assembly 230 provided in an embodiment of this application; Figure 23 A schematic diagram of the assembly structure of the staircase cover assembly 230 provided in an embodiment of this application; Figure 24 This is a schematic diagram of the structure of the transverse baffle portion 2321 provided in an embodiment of this application; Figure 25 This is a schematic diagram of the structure of the flange 2311 provided in an embodiment of this application; Figure 26 This is an isometric schematic diagram of the staircase cover provided in an embodiment of this application; Figure 27 This is a schematic diagram of the structure of the transverse baffle provided in an embodiment of this application; Figure 28 This is a schematic diagram of the structure of the glue injection tank 23214 provided in the embodiments of this application; Figure 29 This is a structural schematic diagram of the first stair baffle 2310 provided in an embodiment of this application; Figure 30 for Figure 29 A cross-sectional structural diagram.

[0088] The large gap between the vehicle body beam and the first-floor staircase 100mm in the downstairs area poses significant challenges to sealing and waterproofing. While the existing staircase cover could achieve partial sealing by applying sealant around the perimeter, the amount and method of application were difficult to control, and any water entering along the stairs would be impossible to drain.

[0089] Therefore, to ensure the seal between the partition wall assembly and the staircase assembly and prevent water from entering the vehicle body and electrical cabinets, the partition wall assembly also includes a staircase cover assembly 230, which includes a first staircase baffle 2310 and a second staircase baffle 2320. The first staircase baffle 2310 is fixed between the first main partition wall 201 and the first-floor staircase 100. The first staircase baffle 2310 is arranged along the width direction of the double-decker rail vehicle and extends from the outlet end of the first-floor staircase 100 towards the inlet end to the end edge of the first main partition wall 201. It diverts water flow from the outlet to the inlet of the first-floor staircase 100, allowing water to drain from top to bottom and preventing water accumulation between the first-floor staircase 100 and the first main partition wall 201. The first stair baffle 2310 is preferably bonded and fixed to the side wall of the first main partition wall 201 and the first floor staircase 100 respectively; thus, the first stair baffle 2310 seals the first main partition wall 201 and the first floor staircase 100.

[0090] The second stair baffle 2320 further blocks the downward flow of water. The second stair baffle 2320 includes a horizontal baffle portion 2321 and a vertical baffle portion 2322, which are connected to each other. The horizontal baffle portion 2321 is located at the end of the first main partition wall 201 and is bonded and fixed to the end wall of the first main partition wall 201 and the side wall of the first staircase 100. The first stair baffle 2310 and the second stair baffle 2320 abut against each other and are bonded together to prevent the downward flow of water from entering the vehicle body through the gap below the first stair baffle 2310.

[0091] The vertical baffle 2322 is installed along the vertical direction of the double-decker rail vehicle and is attached and fixed to the wall surface of the first lower auxiliary partition 2032. Simultaneously, the bottom of the vertical baffle 2322 is fixed to the bottom floor of the double-decker rail vehicle to prevent external rainwater from entering the gap between the first staircase 100 and the first main partition 201, as well as the first accommodating cavity. This prevents water from entering electrical equipment such as electrical cabinets, improving safety. It effectively protects the vehicle body equipment from water corrosion, preventing functional degradation and even reduced lifespan of equipment components.

[0092] The horizontal baffle 2321 and the vertical baffle 2322 are preferably integrated. The edge of the second stair baffle 2320 is bonded and fixed to the wall surface of the first lower auxiliary partition wall 2032, the end wall of the first main partition wall 201, the partition wall of the first stair baffle 2310, and the side wall of the first floor stair 100, respectively, so as to further improve the sealing and energy absorption at this location.

[0093] Furthermore, the first stair baffle 2310 has a downwardly bent flange 2311, which overlaps the inner wall of the first staircase 100.

[0094] The cross-section of the first stair baffle 2310 is a Z-shaped structure. The upper first wall of the Z-shaped structure is connected to the first main partition wall 201, and the lower second wall of the Z-shaped structure is connected to the flange 2311. This arrangement is designed to guide the water flow near the first main partition wall 201 to the side of the first staircase 100, and guide it to the inner wall of the first staircase 100 through the flange 2311, so that it can be cleaned by workers. The Z-shaped structure and the flange 2311 realize the diversion of rainwater, etc., so that the water flow is concentrated and easy to handle.

[0095] In another embodiment, the first stair baffle 2310 can also be inclined downward from the first main wall 201 to the first floor stair 100 to achieve the same effect of guiding the flow; or in other embodiments, the first stair baffle 2310 can be set as needed, as long as the same technical effect can be achieved, all of which are within the protection scope of this application.

[0096] Furthermore, the transverse baffle portion 2321 includes a transverse baffle body, having a first water-blocking facade 23211 and a second water-blocking facade 23212. The first water-blocking facade 23211 is bonded and fixed to the end wall and corner wall of the first main partition wall 201, respectively, and the second water-blocking facade 23212 is bonded and fixed to the end wall of the first stair baffle 2310. The first water-blocking facade 23211 opposite to the first main partition wall 201 and the end wall of the first stair baffle 2310 are provided with a preset inclination angle.

[0097] The transverse baffle also includes a connecting surface 23213, which connects the first water-blocking facade 23211 and the second water-blocking facade 23212. The connecting surface 23213 has an adhesive injection groove 23214. Preferably, the connecting surface 23213 is perpendicular to the first water-blocking facade 23211 and the second water-blocking facade 23212 respectively. The adhesive injection groove 23214 is located on the wall of the connecting surface 23213 and is arranged vertically from top to bottom, thereby increasing the amount of adhesive that can be accommodated and improving the bonding effect.

[0098] In addition, to improve aesthetics, the staircase enclosure assembly 230 also includes an enclosure that covers the first staircase baffle 2310 and the second staircase baffle 2320 and is detachably and fixedly connected to the first staircase baffle 2310 and the bottom floor of the double-decker rail vehicle.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of this application.

[0100] Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application. Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.
