Description

[0002] With the development of my country's social economy and the acceleration of the pace of life, rail transit has become the most important means of transportation in cities. At the same time, the concept of modular design has been widely applied in the field of rail vehicles. By integrating large components of rail vehicles into modules, the assembly of rail vehicles has become increasingly simple and convenient, and it can improve the production efficiency and assembly quality of rail vehicles.

[0003] Currently, external information displays on steel-framed trains are generally mounted on the side walls of the train body near the side doors. To install these displays, a separate opening needs to be made in the side wall near the side door, and a mounting bracket for the display needs to be installed at this opening. For clearer display of train number, origin and destination stations, and carriage sequence numbers, a larger display window near the side door is required. However, the stress at the side wall doorway is significant. If a larger opening is made near the side door in the traditional way to install the external information display, it reduces the load-bearing capacity of the side wall, failing to meet the requirements for safe vehicle operation.

[0061] This invention discloses a sidewall module, a vehicle body, and a rail vehicle to solve the problem that existing external information displays require separate openings in the sidewalls for installation, which reduces the load-bearing capacity of the sidewalls.

[0062] 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.

[0063] Please see Figure 1-5 , Figure 1 This is a structural schematic diagram of a sidewall module provided in an embodiment of this application; Figure 2 This is a schematic diagram of the structure of the vehicle exterior information display window skeleton provided in the first embodiment of this application; Figure 3 This is a schematic diagram of the structure of the vehicle exterior information display window skeleton provided in the second embodiment of this application; Figure 4This is a schematic diagram of the longitudinal beam provided in an embodiment of this application; Figure 5 This is a schematic diagram of the structure of the window module provided in an embodiment of this application.

[0064] In one specific embodiment, the side wall module provided in this application is located at the longitudinal end of the vehicle body and includes two side wall columns 821 and several longitudinal beams 822. The two side wall columns 821 are arranged longitudinally at intervals, and any longitudinal beam 822 is fixed between the two side wall columns 821.

[0065] Window module 823, used for installing vehicle windows, includes two window longitudinal beams 8231, which are located between two side wall columns 821 and are spaced apart vertically.

[0066] The exterior information display window frame 824 is located above the window module 823 and is fixedly connected to the side wall column 821 for fixing the exterior information display.

[0067] Two side wall columns 821 are spaced longitudinally. Here and below, longitudinal refers to the vehicle's direction of travel, and transverse refers to the vehicle's width. The side wall columns 821 constitute the main longitudinal load-bearing components of the side wall, serving as the installation reference and support structure for other components. Several longitudinal beams 822 are present, each fixed between two side wall columns 821, extending longitudinally to enhance the overall rigidity and bending resistance of the side wall, such as when installed in the area below the window. The window module 823 is used to install the vehicle window. It includes two window longitudinal beams 8231, which are spaced vertically to form a rectangular frame structure. This frame defines the window area, forming the installation boundary and sealing base of the window, improving the support and clamping structure of the window glass, and making the window area structure an independent "module" for easy prefabrication, assembly, and replacement. The exterior information display window frame 824 is located in the upper area of ​​the window, above the window module 823, and is fixedly connected to the side wall column 821. It is used to fix the exterior information display, which typically displays the train number, destination station, and next station. The exterior information display window frame 824 is separately installed on the side wall module, providing strength for the integrated exterior information display. Compared to existing technologies, this allows for the installation of larger exterior information displays, simplifies the window structure, effectively frees up installation space, and supports the installation of larger-sized exterior information displays. The side wall column 821 is preferably a B-shaped profile, and the longitudinal beam 822 is preferably a U-shaped profile; in other embodiments, the profile structure can be designed as needed, all within the scope of this application.

[0068] Compared with the prior art, the sidewall module, vehicle body, and rail vehicle provided in this application have the following technical advantages:

[0069] The side wall module includes two side wall columns 821 and several longitudinal beams 822. The two ends of the longitudinal beams 822 are fixed to the side wall columns 821 respectively. The window module 823 is used to install the vehicle window, which includes two window longitudinal beams 8231 located between the side wall columns 821. The exterior information display window frame 824 is located above the window module 823 and is fixedly connected to the side wall columns 821. It provides an interface for the installation of the exterior information display, making assembly simple, improving production efficiency and assembly quality. Compared with the prior art, it can provide a larger exterior information display window, simplify the structure of the exterior information display window, and facilitate the installation of the exterior information display.

[0070] In one alternative embodiment, the exterior information display window skeleton 824 includes:

[0071] A top beam 8241 and a bottom beam 8242 are arranged vertically at intervals, and the two ends of the bottom beam 8242 are fixed to the side wall columns 821 respectively.

[0072] Two vertically extending monitor window pillars 8243 are provided, with one end of the monitor window pillar 8243 fixed to the top beam 8241 and the other end fixed to the bottom beam 8242.

[0073] The top beam 8241 and the bottom beam 8242 extend longitudinally and are spaced vertically, i.e., distributed vertically. They form the upper and lower boundaries of the display frame, providing support and fixing points for the upper and lower edges of the display, and enhancing the frame's bending resistance under vertical loads. The top beam 8241 is indirectly connected to the side wall through the display window pillar 8243, which facilitates the adjustment of the height of the top beam 8241 to adapt to different vehicle models or display sizes. There are two display window pillars 8243, which extend vertically. The upper end of the display window pillar 8243 is fixed to the top beam 8241, and the lower end is fixed to the bottom beam 8242, forming the left and right boundaries of the display frame and providing lateral support and installation reference for the display.

[0074] Specifically, the top beam 8241 can be set as a type B profile, and the bottom beam 8242 can be set as a type U profile; the exterior information display window frame 824 also includes several external display reinforcing plates 8244, located on the inner surface of the bottom beam 8242, for fixing to the exterior information display with bolts; that is, the external display reinforcing plates 8244 are set on the inner surface of the transverse inner side of the bottom beam 8242, and are used for reinforcement when the exterior information display is fixed to the bottom beam 8242 with bolts; it is understood that it is preferable to set mounting holes on the inner and outer surfaces of the bottom beam 8242 respectively, and the external display reinforcing plates 8244 are set one-to-one with the mounting holes.

[0075] In one embodiment, at least two vertical beams 825 are further included, located vertically between the exterior information display window frame 824 and the window module 823. One end of each vertical beam 825 is fixed to the bottom beam 8242, and the other end is fixed to the top window longitudinal beam 8231 of the window module 823. There are at least two vertical beams 825, which can be symmetrically arranged in the vertical space between the display window frame and the window module 823, and extend vertically. The upper end of each vertical beam 825 is fixed to the bottom beam 8242, and the lower end is fixed to the top window longitudinal beam 8231 of the window module 823, thereby enhancing the bending stiffness of the sidewall in both the vertical and longitudinal directions. Simultaneously, the load can be transferred to the window module 823 through the vertical beams 825, achieving load sharing, resulting in greater structural stability under vehicle vibration or external impact.

[0076] In one embodiment, the sidewall module further includes at least two window-under pillars 826, each window-under pillar 826 being located below the window module 823. At least one row of longitudinal beams 822 is provided between the window-under pillars 826 and the sidewall pillars 821, and between the two window-under pillars 826. Typically, two window-under pillars 826 are provided, located below the window module 823, in the vertical area between the window and the floor. They are used to share the vertical load of the main sidewall pillars 821, enhancing the local stiffness of the window-under skin area and preventing bulging or deformation caused by negative pressure, vibration, or foot traffic. Simultaneously, at least one row of longitudinal beams 822 is provided between the main pillar and the window-under pillars 826, and between the two window-under pillars 826, forming a structural network that supports the skin and interior trim. This forms a multi-grid reinforcement structure in the window-under area, improving the out-of-plane stiffness of that area. Preferably, two rows of longitudinal beams 822 are provided between the window support column 826 and the side wall support column 821, and between the two window support columns 826. The rows of longitudinal beams 822 in each area are aligned longitudinally to further improve rigidity.

[0077] Furthermore, it also includes a lumbar beam 827, located vertically between the window module 823 and the longitudinal beam 822 below the window module 823; lumbar beams 827 are also provided between the window base column 826 and the side wall column 821, and between the two window base columns 826. The window module 823 is above the lumbar beam 827, and the longitudinal beam 822 is below it. The lumbar beam 827 is located in the middle height area between the window module 823 and the longitudinal beam 822, serving as an intermediate support layer, shortening the span between the main longitudinal beams 822, and enhancing the out-of-plane stiffness of the side wall in the upper middle area.

[0078] In one optional embodiment, the two window longitudinal beams 8231 and the two side wall columns 821 constituting the window module 823 are each provided with a plurality of window mounting holes 8232. The horizontal plane of the window longitudinal beams 8231 and the vertical plane of the side wall columns 821 are also provided with a plurality of window mounting holes 8232 to secure the window. The window is connected to the window mounting holes 8232 on the window module 823 by bolts, and sealant is applied to the gap between the window and the window frame.

The roof longitudinal beams 802 extend longitudinally and connect to the roof beams 801, providing continuous longitudinal support, enhancing the overall rigidity of the roof, and forming a spatial frame. A corrugated roof panel 803 is located in the central area of ​​the roof structure 80, fixed above the roof beams 801. The corrugated structure improves compressive, bending, and shear resistance, facilitating the bearing of concentrated loads.

The corrugated roof panel 803 located in the central area provides central load-bearing, while the side flat roof panels 804 installed on both sides enable lateral installation, optimizing the layout and achieving a modular design with good assembly processability. It also reduces additional reinforcing components, lowering material and processing costs.

The middle area of ​​the passenger compartment air conditioning flat roof frame is provided with a passenger compartment air conditioning installation interface 8051 for installing a passenger compartment air conditioning unit.

[0088] The passenger compartment air conditioning flat roof structure 805 is used to support and install the passenger compartment air conditioning unit; the passenger compartment air conditioning flat roof frame is located on the top of the side wall 82, supporting the passenger compartment air conditioning roof plate and the air conditioner, and transferring the load to the main body; the passenger compartment air conditioning flat roof plate is a skin covering the passenger compartment air conditioning flat roof frame; a passenger compartment air conditioning installation interface 8051 is set in the middle area of ​​the passenger compartment air conditioning flat roof structure 805, and correspondingly, both the passenger compartment air conditioning flat roof frame and the passenger compartment air conditioning flat roof plate are provided with installation interfaces. The passenger compartment air conditioning installation interface 8051 is specifically an interface channel steel and an air supply and return air vent; at the same time, air conditioning guide hood mounting seats are set on both sides of the passenger compartment air conditioning flat roof structure 805 for installing the air conditioning guide hood.

[0089] Understandably, the air conditioning installation interface is preferably located at the center of the passenger compartment air conditioning ceiling frame to ensure that the center of gravity of the air conditioning unit is matched and the force is evenly distributed; the air conditioning installation interface is pre-installed in the frame to avoid drilling on site and improve assembly efficiency; one end is centrally arranged to reduce pipeline length and improve the utilization rate of interior space.

[0090] In another embodiment, the roof structure 80 further includes:

The driver's cab air conditioning flat roof frame is used to support the driver's cab air conditioning flat roof plate and air conditioning unit, and transfer the load to the vehicle body to ensure structural safety. Similarly, the driver's cab air conditioning installation interface 8061 is preferably located at the center of the driver's cab air conditioning flat roof frame to ensure that the center of gravity of the air conditioning unit is matched and the force is evenly distributed. The driver's cab air conditioning installation interface 8061 is pre-installed in the driver's cab air conditioning flat roof frame to avoid on-site drilling and improve assembly efficiency.

[0093] In one alternative embodiment, there are several roof longitudinal beams 802;

[0094] A roof longitudinal beam 802 is located on the longitudinal central axis of the roof and extends longitudinally along the vehicle body;

[0095] The overlapping joint area of ​​the corrugated roof panel 803 and the side flat roof panel 804 is provided with roof longitudinal beams 802, and / or, the side flat roof panel 804 is provided with a number of roof longitudinal beams 802.

[0096] Specifically, a roof longitudinal beam 802 is installed along the longitudinal center axis of the vehicle to support the middle of the corrugated roof panel 803, resist concentrated loads, serve as the main longitudinal force transmission path, connect the front and rear structures, improve torsional stiffness, and prevent vehicle body twisting. Simultaneously, a roof longitudinal beam 802 is installed at the joint between the corrugated roof panel 803 and the side flat roof panel 804 to provide continuous support, preventing the panels from deforming due to suspension; it also enhances the joint strength, preventing cracking due to vibration or thermal expansion and contraction. Furthermore, one or more longitudinal beams are independently installed under each side flat roof panel 804 to achieve localized reinforcement, improve lateral bending resistance, and provide reliable mounting points for interior components such as lights, air ducts, and armrests.

[0097] The use of multiple roof longitudinal beams 802 layouts distributes the load and provides strong resistance to bending and torsion. Roof longitudinal beams 802 are installed at the lap joints to prevent cracking or water leakage. At the same time, the uniformity of support is improved, and the roof longitudinal beams 802 serve as positioning references to enhance the efficiency of automated assembly.

[0098] In another embodiment, the roof structure 80 further includes:

[0099] The water tank cover structure 807 includes a water tank cover and a water tank cover mounting frame. The water tank cover mounting frame is located above the roof curved beam 801 and has a water tank cover mounting interface in the middle.

[0101] The water tank cover structure 807 is used to close the water tank access port on the roof. The water tank cover mounting frame is fixed on the roof curved beam 801, providing an installation reference, enhancing local strength, and preventing deformation. The water tank cover mounting interface is located in the middle of the water tank cover mounting frame and is used to accommodate the water tank cover, enabling quick opening and closing. The water tank cover is placed on the water tank cover mounting interface and can be connected by bolts, quick-release locks, etc., facilitating regular maintenance, cleaning, or replacement of water tank components. The water tank cover is made of corrugated plate to improve strength. Its waveform, curvature, and pitch are consistent with the contour surface of the corrugated roof plate 803 to ensure continuous appearance and good aerodynamic performance.

[0102] Specifically, the water tank cap mounting frame is welded or riveted above the roof curved beam 801 to form a reinforcing ring. The water tank cap covers the mounting frame and is flush with the surrounding corrugated roof plate 803, forming a continuous corrugated surface. There are no abrupt changes in the cross section, which reduces air resistance and noise.

[0127] In one specific embodiment, the driver's cab underframe front end assembly 81100 provided in this application includes a driver's cab end beam 811, an anti-climb mounting base 812, a reinforcing base 813, and a support plate 814. The driver's cab end beam 811, as the main load-bearing structure at the front end of the car body underframe, bears the forces transmitted from various structures such as the anti-climb device, the support plate, and the rear baffle 81500, and is generally made of high-strength steel. The anti-climb mounting bases 812 are arranged in pairs on both sides of the driver's cab end beam 811, serving as the mounting base for the anti-climb device. They absorb energy during a collision, reduce the impact force transmitted to the interior of the car, and prevent derailment or crushing during a head-on collision.

[0128] Behind each anti-climb mounting seat 812 is a corresponding reinforcing seat 813. The reinforcing seat 813 is fixed to the longitudinal rear side of the driver's cab end beam 811 for support and reinforcement. The reinforcing seat 813 is usually welded from steel plates and is L-shaped or T-shaped. It is welded and fixed to the driver's cab end beam 811 to enhance the connection strength between the anti-climb mounting seat 812 and the driver's cab end beam 811, improve the local structural rigidity, and avoid stress concentration that could lead to cracking.

[0129] Meanwhile, a corresponding support plate assembly 814 is provided behind each anti-climb mounting seat 812. The support plate assembly 814 is located on the rear side of the driver's cab end beam 811 and is continuously arranged longitudinally with the anti-climb mounting seat 812. The other end is used to fix it to the rear baffle 81500, realizing the structural transition from the anti-climb mounting seat 812 to the rear baffle 81500. The support plate assembly 814 is welded and fixed to the driver's cab end beam 811.

[0130] The driver's cab underframe front end assembly 81100, underframe, and rail vehicle provided in this application embodiment have the following technical advantages compared to the prior art:

[0131] Anti-climbing mounting seats 812 are symmetrically provided on the transverse sides of the cab end beam 811. A reinforcing seat 813 is provided at the rear side of each anti-climbing mounting seat 812 for support and reinforcement, enhancing the connection strength between the anti-climbing mounting seat 812 and the cab end beam 811, while improving the local structural stiffness and avoiding cracking caused by stress concentration. At the same time, each anti-climbing mounting seat 812 also corresponds to a support plate assembly 814 to achieve the structural transition from the anti-climbing mounting seat 812 to the rear baffle 81500, forming a continuous force path, enhancing the overall bearing capacity, and ensuring stable and reliable load transfer.

[0132] In a specific embodiment, the front-end assembly 81100 of the cab underframe further includes a first inclined support beam assembly 815. One end is fixed at the connection of the cab end beam 811 and the support plate assembly 814, and the other end is used to be fixed to the cab side beam 81400.

[0133] And / or, a second inclined support beam assembly 816. One end is fixed at the connection of the cab end beam 811 and the support plate assembly 814, and the other end is used to be fixed to the cab end traction beam assembly 81200.

[0134] The first inclined support beam assembly 815 is connected to the connection area between the cab end beam 811 and the support seat assembly, and the other end is connected to the cab side beam 81400 of the car body, arranged obliquely, forming a force path from the front end of the underframe to the side structure. The second inclined support beam assembly 816 is also connected at one end to the connection area between the cab end beam 811 and the support plate assembly 814, and the other end is connected to the cab end traction beam assembly 81200, also arranged obliquely, constituting a force path from the front end to the bottom traction structure. The inclined support beam assembly forms a three-dimensional force framework by connecting the front-end structure to the cab side beam 81400 or the traction beam, significantly enhancing the bending and torsional resistance of the front-end assembly 81100 of the cab underframe. Under frontal collision or traction conditions, the load can be more evenly transferred to the cab side beam 81400 or the traction beam through the inclined support beam, reducing local stress concentration and preventing cracking of weak parts. The inclined support beam assembly can be set as a box beam, using standard profiles or welded components, which is convenient for mass production. The cross-sections of both the first inclined support beam assembly 815 and the second inclined support beam are in the shape of a C.

[0135] In another embodiment, the anti-climbing mounting seat 812 includes:

[0136] An anti-climbing energy-absorbing cover 8121 and an anti-climbing tooth mounting panel 8122. The anti-climbing tooth mounting panel 8122 is located in front of the anti-climbing energy-absorbing cover 8121.

[0137] A reinforcing pipe 8123, located inside the anti-climbing energy-absorbing cover 8121, fixed to the anti-climbing tooth mounting panel 8122 at the longitudinal front side and butted against the cab end beam 811 at the longitudinal rear side.

[0138] Both the anti-climb energy-absorbing cover 8121 and the reinforcing tube 8123 have guiding holes 8124 on their longitudinal front sides.

[0139] The anti-climb tooth mounting panel 8122, serving as the mounting base for the anti-climb device, is typically made of high-strength steel plate, possessing excellent impact resistance, and features multiple mounting holes or positioning slots for easy assembly. Behind the anti-climb tooth mounting panel 8122 is an anti-climb energy-absorbing cover 8121, forming a semi-enclosed space to accommodate the reinforcing tube 8123, which has energy-absorbing capabilities and undergoes controllable compressive deformation during a frontal impact. The reinforcing tube 8123 is located inside the anti-climb energy-absorbing cover 8121, connecting longitudinally to the anti-climb tooth mounting panel 8122 at its front and longitudinally to the driver's cab end beam 811 at its rear. It can be made of hollow steel pipe or irregularly shaped cross-section profiles, possessing high axial crush strength; different specifications of reinforcing tubes can be used to meet different collision energy absorption requirements. Simultaneously, induction holes 8124 are provided on the longitudinally front sides of the anti-climb energy-absorbing cover 8121 and the reinforcing tube 8123 to guide the material to buckle or fold along a predetermined direction under pressure, thereby improving energy absorption efficiency and preventing brittle fracture of the structure. The guiding holes 8124 are strip-shaped holes, respectively set in the circumference of the anti-climb energy-absorbing cover 8121 and the circumference of the reinforcing tube 8123. The anti-climb energy-absorbing cover 8121 is set as a rectangular structure.

[0140] The reinforcing tube 8123 extends from the anti-climbing tooth mounting panel 8122 to the driver's cab end beam 811, forming a high-rigidity force transmission channel; it can effectively withstand traction, braking force, and coupler loads; and improve the overall vehicle running stability. In the event of a head-on collision, the anti-climbing mounting seat 812 is the first to bear the brunt, preventing vehicle stacking through the anti-climbing teeth; the energy-absorbing cover and the reinforcing tube 8123 undergo controllable compression deformation, absorbing a large amount of kinetic energy; the presence of the induction hole 8124 ensures that deformation proceeds in the expected manner, avoiding sudden breakage or instability.

[0141] Meanwhile, to enhance the connection stability between the reinforcing tube 8123 and the driver's cab end beam 811, the aforementioned anti-climb mounting base 812 also includes a tube seat 8125, which is fixed to the driver's cab end beam 811. The tube seat 8125 is a sleeve-type structure, fitted onto the outside of the reinforcing tube 8123, serving a positioning and support function. It is fixed to the driver's cab end beam 811 by welding. It is understood that the inner diameter of the tube seat 8125 is slightly larger than the outer diameter of the reinforcing tube 8123, facilitating assembly and allowing for a certain amount of deformation space. The tube seat 8125 provides an additional support point for the reinforcing tube 8123, preventing it from shifting or becoming unstable due to excessive force; and improving the overall structural rigidity.

[0142] In another embodiment, the reinforcing seat 813 sits on the support plate assembly 814, including an inclined plate and two side plates located at the lateral ends of the inclined plate;

[0143] The top of the inclined plate has a horizontal bend extending in the horizontal direction, and the bottom has a vertical bend extending downward in the vertical direction. The horizontal bend and the vertical bend are located on the same side of the inclined plate. The middle section of the inclined plate is also provided with a reinforcing part, which is flush with the top of the reinforcing tube 8123 in the vertical projection direction.

[0144] The inclined plate is arranged at an angle, allowing the load to be smoothly transferred from the anti-climb mounting base 812 to the driver's cab end beam 811. Reinforcing ribs or ribs can be added to improve local rigidity. The horizontal bend is located at the top of the inclined plate and extends towards the driver's cab end beam 811, connecting to it. The vertical bend is located at the bottom of the inclined plate, extending downwards in the vertical direction and resting on the support plate assembly 814, where it is welded and fixed, enhancing the bottom connection strength. The reinforcement is located in the middle section of the inclined plate, flush with the top of the reinforcing tube 8123 in the straight projection direction. This aims to create a matching structural height, allowing the force transmitted from the reinforcing tube 8123 to act directly on the reinforcement. This can be a thickened area, welded ribs, or a locally protruding structure. The angle design of the inclined plate facilitates smooth force transmission; the bend provides multi-directional connection interfaces to adapt to different assembly requirements; the alignment of the reinforcement with the top of the reinforcing tube 8123 ensures uniform stress distribution in critical areas.

[0145] Furthermore, the aforementioned driver's cab underframe front end component 81100 also includes a reinforcing plate 817, which is fixedly installed on the longitudinal rear vertical surface of the driver's cab end beam 811 (i.e., the side facing the middle of the vehicle body); it is aligned or overlapped with part of the reinforcing tube 8123 in the vertical direction to form force flow matching; it is usually made of high-strength steel plate, which can be fixed to the driver's cab end beam 811 by welding, bolts, etc.; it can be in the form of a single piece or multiple pieces, and the overall rigidity is enhanced by setting the reinforcing plate 817.

[0146] In one embodiment, the underframe of this application includes a driver's cab underframe front end assembly 81100, a driver's cab end traction beam assembly 81200, a bolster beam assembly 81300, a bolster-inner driver's cab crossbeam 81600, a coupler mounting seat 81700, a bolster-inner longitudinal beam assembly, a floor assembly 81800, a driver's cab side beam 81400, a rear tailgate 81500, and a plurality of driver's cab crossbeams 81600; the driver's cab end traction beam assembly 81200 is located in the vehicle... In the middle of the vehicle body, the driver's cab side beam 81400 is located on both sides of the vehicle body, and several driver's cab crossbeams 81600 are provided between the driver's cab side beam 81400 and the driver's cab end traction beam assembly 81200; the bolster beam assembly 81300 is located on the longitudinal rear side of the driver's cab end traction beam assembly 81200; the rear baffle 81500 is located on the rear side of the driver's cab end beam 811, and is located transversely between the driver's cab side beam 81400 and the driver's cab end traction beam assembly 81200.

[0147] The driver's cab crossbeam 81600 is directly connected to the driver's cab end traction beam 81200, reducing the height of the driver's cab crossbeam 81600, unifying the height of the iron floor in the driver's cab area and the passageway area, reducing the difficulty of the process and increasing the internal space of the driver's cab; at the same time, the support plate 814 of the front end of the driver's cab underframe 81100 is set one plate thickness lower than the floor, unifying the height of the iron floor in the driver's cab area and the passageway area, reducing the difficulty of the process and increasing the internal space of the driver's cab.

[0148] The coupler mounting base 81700 is located at the longitudinal front end of the driver's cab end traction beam assembly 81200, and its two transverse ends protrude from the driver's cab end traction beam assembly 81200. By welding the coupler mounting base 81700 against the end face of the single traction beam, the weld seam is no longer subject to shear load transfer. The tensile and compressive loads on the coupler mounting base 81700 are directly transferred to the single traction beam, thus improving the load-bearing capacity.

[0149] In another embodiment, the end wall 83 includes:

[0150] The wall consists of a main beam 83110, end wall panels 83120, end wall columns 83130, corner columns 83140, and intermediate columns 83150. The upper ends of the end wall columns 83130 and corner columns 83140 are connected to the main beam 83110. Intermediate columns 83150 and end wall beams are interlaced between the end wall columns 83130 and corner columns 83140. The upper end of the intermediate columns 83150 is connected to the main beam 83110. The end wall panels 83120 are laid sequentially along the vertical direction of the end wall 83.

[0151] The main crossbeam 83110 serves as the upper transverse main load-bearing component of the end wall 83, connecting the corner columns on both sides, supporting the roof load, and transmitting longitudinal force. The end wall column 83130 is a vertical load-bearing column, which bears compression, tension, and bending moment. The corner columns 83140 are located at the four corners of the end wall 83, bearing concentrated loads and connecting the side wall 82 and the base frame 81. The intermediate column 83150 is used to enhance local fixation and support the end wall panel 83120. The crossbeams of the end wall 83 are arranged horizontally to form a grid structure to prevent panel buckling. The tops of all columns are uniformly connected to the main crossbeam 83110 to achieve load convergence. The end wall panels 83120 are spliced ​​from bottom to top or from top to bottom along the height direction to facilitate drainage and reduce transverse joints.

[0152] The central column 83150 has a B-shaped cross-section and weight-reduction holes on its facade to achieve a lightweight design. The end wall 83 is a cold-formed steel structure, with the lower hole of the windshield mounting hole located on the buffer beam of the underframe 81. The two sides of the end are B-shaped end face cross bearings to optimize the interface between the roof structure 80 and the end beam.

[0153] In an alternative embodiment, an inner end wall 8583 is also included, located at one end near the driver's cab 84; the periphery of the inner end wall 8583 is welded to the side wall 82 frame of the side wall 82 and the roof beam 801 of the roof structure 80.

[0154] The inner end wall 8583 separates the passenger compartment space from the equipment room space. Due to the two pairs of doors and the water tank cover structure 807 set in the middle of the vehicle, the rigidity of the middle of the vehicle body is reduced. The inner end wall 8583 is used to improve the rigidity of the middle, thereby improving the rhomboid mode of the vehicle body. At the same time, the perimeter of the inner end wall 8583 structure is welded with the side wall 82 frame and the roof curved beam 801 to form a stable frame.

[0155] In another embodiment, a barrier clearing structure is provided below the end of the driver's cab 84 to remove obstacles on the track during vehicle operation and protect the vehicle's operational safety. Four sets of mounting brackets are provided on the upper part of the barrier clearing device to fix it to the underframe 81 of the vehicle body; simultaneously, three sets of fasteners on each side secure the barrier clearing device to the skirt of the driver's cab 84, forming a unified whole; a main barrier clearing device is provided at the front end, reinforced and supported internally by a frame structure, capable of clearing obstacles of larger size and weight; a height-adjustable small barrier clearing device is provided in the lower middle part to clear small, lightweight obstacles.

[0156] Specifically, the outer corner weld between the underframe 81 and the side wall 82 is fully welded and ground smooth, and the inner side is sealed with glue; the underframe 81 and the end wall 83 are fully welded on both sides, and the inner side is sealed with glue after welding; the underframe 81 and the front wall of the driver's cab 84 are partially welded and glued on the outer side, and fully welded on the inner side; the underframe 81 and the side wall 82 of the driver's cab 84 are fully welded on the outer side, and the inner root is sealed with glue; the side wall 82 and the roof are fully welded on the outer side in the high roof area and ground smooth, and a small side roof plate is added for connection in the flat roof area, all of which are fully welded; the side wall 82 and the end wall 83 and the side wall 82 of the driver's cab 84 are fully welded on the outer side; the roof and the flat top wall 83, and the roof and the top of the driver's cab 84 are fully welded on the outer side.

[0157] While ensuring ample passenger space, the aforementioned car body optimizes the layout of overhead equipment, reducing the height of the car body from the rail surface from 4433mm to 4180mm and adjusting the curvature of the roof. This ensures sufficient space for both passengers and overhead equipment installation, while simultaneously achieving weight reduction by minimizing the car body's cross-sectional area. Replacing the traditional flat plate structure with a large-section cold-pressed corrugated structure significantly improves the vertical stiffness of the roof plate, while reducing the roof plate thickness from 2mm to 1.5mm. The number of longitudinal beams on the roof is reduced from 13 to 7, simultaneously improving the car body's first-order vertical bending mode, roof plate flatness, and overall weight reduction. Through structural topology and material optimization, the weight of the car body steel structure is controlled to 17.4t using high-strength, lightweight carbon steel, a reduction of 600kg compared to products on the same platform, representing a 3% weight reduction.
