[0072] The sealed side door 934 is detachably and fixedly connected to the door frame embedding opening 933 after the sealed side door 934 is spliced ​​with the upper box 931 and the lower box 932.

[0073] The upper container 931 and the lower container 932 are detachably fixed, for example, by using threaded fasteners 93105 to achieve splicing; when the container is handled or transported, the upper container 931 and the lower container 932 can be transported and handled separately, reducing the labor intensity of the workers; at the same time, the container is assembled according to the goods to be transported, which can consolidate bulk goods into wholes and simplify the process, realizing "unitized transportation" of freight.

[0074] The upper housing 931 and the lower housing 932 can have the same or different structures. For example, both are preferably designed as cuboid structures to facilitate production and processing, and their regular shape facilitates handling and transportation. It is understood that the upper housing 931 has an inner cavity, and the lower housing 932 also has an inner cavity. The side walls of the upper housing 931 and the lower housing 932 are respectively provided with partial door frame insertion openings 933. After the upper housing 931 and the lower housing 932 are assembled, their inner cavities are aligned and assembled to form the complete inner cavity of the container, and the partial door frame insertion openings 933 are aligned and assembled to form a complete inner frame insertion opening for installing the sealing side door 934.

[0075] Compared with the prior art, the container and rail vehicle provided in this application have the following technical advantages:

[0076] The upper container 931 and the lower container 932 adopt a splicing structure. Each of them has a splicable inner cavity and a door frame insertion port 933. The sealed side door 934 is detachably and fixedly connected to the spliced ​​door frame insertion port 933. The above-mentioned container can be quickly assembled and can be adapted to local conditions according to the characteristics of the goods to consolidate bulk goods and simplify complex operations. It is convenient for disassembly, handling, storage and piecework, thereby improving transportation efficiency and quality, reducing cargo damage and loss during transportation, realizing the mechanization of loading and unloading operations, reducing the labor intensity of workers, reducing operation time and accelerating vehicle turnaround.

The sealing top plate 93101 is located on top of the upper box body 93102 and is detachably and fixedly connected to the upper box body 93102. Optionally, the sealing top plate 93101 and the upper box body 93102 are fixed by bolts. The sealing top plate 93101 serves as an opening structure for the upper box body 93102, assembled after the goods are installed on the upper box body 93102, thus completing the loading and unloading of goods on the upper box body 93102. This provides convenient loading and unloading space for the upper box body 93102, facilitating operations and further improving loading and unloading efficiency. The upper box 931 is preferably configured as a trapezoidal or rectangular structure, and its specific shape can be set as needed, all of which are within the protection scope of this application.

[0078] Meanwhile, the container also includes an electrical installation panel 935, which is located in the inner cavity of the upper housing body 93102 and is vertically positioned between the sealing top plate 93101 and the upper housing body 93102. The circumferential edge of the electrical installation panel 935 overlaps with the circumferential edge of the upper housing body 93102 and is fixed to the upper housing body 93102 by the sealing top plate 93101, simplifying the fixing structure and steps with the upper housing body 93102 and facilitating disassembly and assembly.

[0079] The electrical installation panel 935 is used to install various types of electrical components, such as temperature and humidity sensors, smoke sensors, or controllers. The electrical installation panel 935 provides installation space for electrical components without occupying other space in the upper housing body 93102, making the inner cavity of the upper housing body 93102 neat and tidy, and improving the space utilization rate of the upper housing body 93102.

[0080] Specifically, the top of a set of opposite sidewalls of the upper housing body 93102 is provided with a recessed mounting notch 93103. The mounting notch 93103 is used to support the electrical mounting tray 935. Preferably, the mounting notch 93103 is provided on a set of opposite sidewalls in the horizontal direction of the upper housing body 93102. The mounting notch 93103 is recessed, and the vertical projection of the mounting notch 93103 is trapezoidal, which is adapted to the shape of the outer wall of the electrical mounting tray 935. In other embodiments, the shape of the mounting notch 93103 can be set according to the shape of the electrical mounting tray 935.

[0083] In another embodiment, the electrical installation panel 935 is provided with:

[0084] The refrigeration compressor 936 has a cold air output port that is connected to the inner cavity of the upper housing body 93102, and is used to supply cold air to the inner cavity of the container;

[0085] Temperature and humidity detection component 937, with the detection end located in the inner cavity of the upper housing body 93102, is used to detect the temperature and humidity inside the container;

[0086] The smoke detection component 9388 has its detection end located in the inner cavity of the upper housing body 93102 and is used to detect the smoke concentration inside the container.

[0087] Tilt detection assembly 939 is used to detect the horizontal tilt angle of the container;

[0088] The control component 9310 is located inside the electrical installation panel 935 and is connected to the refrigeration compressor 936, the temperature and humidity detection component 937, the smoke detection component 9388, and the tilt detection component 939, respectively.

[0089] The GPRS module 9311 is located inside the electrical installation panel 935 and is connected to the control component 9310. It is used to upload data to the host computer.

[0090] Understandably, the cold air generated by the refrigeration compressor 936 enters the upper chamber 931 and lower chamber 932, achieving a refrigeration and preservation effect. Temperature and humidity sensors and a smoke sensor facilitate monitoring of internal temperature, humidity, and smoke concentration. The smoke sensor has a detection accuracy of 5 ppm and an operating temperature range of -20 to 60℃.

Each electrical device transmits the detected data information to the microcontroller controller for analysis and processing, and finally transmits the data remotely through the GPRS module 9311 to establish a data sharing platform and realize data sharing.

[0093] Optionally, the container also includes a power supply assembly 9312, located within the electrical mounting panel 935, and connected to the refrigeration compressor 936 and the control assembly 9310 respectively. The power supply assembly 9312 is located within the electrical mounting panel 935 and on one side of the refrigeration compressor 936. The power supply assembly 9312 is fixed to the electrical mounting panel 935 with screws. The power supply assembly 9312 is a UPS (Uninterruptible Power Supply), which facilitates the supply of power to the refrigeration compressor 936, the microcontroller controller, and the heater, enabling them to operate stably.

[0094] The power indicator 9313 is located on the outer wall of the electrical mounting panel 935 and is connected to the power supply assembly 9312. It is used to display the remaining power of the power supply assembly 9312. The outer wall of the electrical mounting panel 935 is also provided with several heat dissipation holes 9351. The heat dissipation holes 9351 improve the heat dissipation effect of the electronic components inside the electrical mounting panel 935, and the power indicator 9313 facilitates the display of the remaining power of the UPS power supply, making it easy for personnel to know.

[0095] The container also includes:

[0096] The insulated box 9314 is located on the outer bottom of the lower box 932, and the insulated box 9314 is detachably and fixedly connected to the lower box 932.

[0098] The lower box 932 has an insulated box 9314 bolted to the other side of its bottom end. A heater is mounted on one side of the insulated box 9314 via a mounting base. A sealing cover is connected to the top of the insulated box 9314 via a rotating shaft. The heater facilitates heating the inside of the insulated box 9314 to achieve insulation, making it convenient to place items that need to be insulated. It is practical and effective.

[0099] Furthermore, a storage partition 9317 is bolted inside the lower housing 932. The storage partition 9317 inside the container facilitates the separation of goods and avoids mutual interference.

[0100] Meanwhile, the bottom surface of the lower housing 932 is provided with a base 9316. The base 9316 is welded to the lower housing 932 or connected by threaded fasteners 93105. The base 9316 is provided with a set of forklift reserved openings 93161, which facilitates handling by forklift, improves stability during handling, and prevents the container from tilting during handling by forklift.

[0101] The container provided in this application, when in operation, has its upper housing 931 snapped onto the top of the lower housing 932, its connecting bolts screwed into the first and second mounting holes, its electrical mounting plate 935 placed into the mounting notch 93103, and its sealing top plate 93101 pressed and fixed in place. Finally, the door frame and the sealing side door 934 are embedded into the door frame embedding opening 933, realizing the overall assembly of the container, which is convenient to operate and saves manpower and physical resources. Forklift handling is achieved via the forklift access port 93161 on the base 9316, improving stability. The storage partition 9317 inside the container separates the goods. Cold air generated by the refrigeration compressor 936 enters the upper compartment 931 and lower compartment 932, achieving a refrigeration and preservation effect, preventing food spoilage due to high temperatures. Temperature and humidity sensors, smoke sensors, and tilt sensors update data in real time, transmitting the detected data to the microcontroller for analysis and processing. Finally, data is remotely transmitted via the GPRS module 9311, establishing a data sharing platform for data sharing. The smoke sensor monitors the fire situation inside the compartment in real time; upon detection of a fire, an alarm is triggered and the data is uploaded to the platform system.

[0102] Based on the container provided in the above embodiments, this application also provides a rail vehicle, which includes a driver's cab and a carriage connected to the driver's cab. The carriage is equipped with any of the containers in the above embodiments. Since the rail vehicle uses the container in the above embodiments, the beneficial effects of the rail vehicle can be found in the above embodiments.

[0103] Please refer to Figures 6 and 7. Figure 6 is a structural schematic diagram of a driver's cab provided in an embodiment of this application; Figure 7 is a structural schematic diagram of the steel structure of the driver's cab provided in this application.

[0104] In one specific embodiment, the driver's cab provided in this application includes a driver's cab steel structure 10 and an integrated driver's cab headgear 20. The driver's cab headgear 20 is situated on and fixed to the driver's cab steel structure 10. The driver's cab headgear 20 located in the top area of ​​the driver's cab adopts an integrated fiberglass sandwich structure. The driver's cab headgear 20 includes two fiberglass layers and a sandwich layer in the middle. The sandwich layer is specifically a pre-embedded polymethyl methacrylate (PMI) foam layer. The integrated fiberglass sandwich structure facilitates the control of the dimensional accuracy of the driver's cab headgear 20 after molding, improves the accuracy control of the three-dimensional interface dimensions of the windshield, external lighting, headlight glass, and windshield wipers, and facilitates the installation of three-dimensional components such as the windshield, external lighting, headlight glass, and windshield wipers. The driver's cab steel structure 10 located in the bottom area of ​​the driver's cab consists of a steel frame and a skin. The steel frame is a carbon steel metal frame. By setting the driver's cab headgear 20, the scope of the driver's cab steel structure 10 is reduced, the manufacturing costs of molds, gauges, bending parts, etc. are reduced, and the economy is improved. The fiberglass of the driver's cab head cover 20 has a lower density than carbon steel, and reducing the range of the driver's cab steel structure 10 helps to achieve lightweighting of the driver's cab head structure.

[0105] In addition, the joint between the driver's cab hood 20 and the driver's cab steel structure 10 should be located on a simple, smooth surface with minimal curvature variation, so as to facilitate the streamlined matching of the driver's cab hood 20 and the driver's cab steel structure 10 during installation, while reducing the manufacturing difficulty of the frame and skin components of the driver's cab steel structure 10 and improving economy; the curvature at the joint between the driver's cab hood 20 and the side wall of the driver's cab steel structure 10 is small, and the location with a large curvature variation between the side surface and the top surface is located on the fiberglass hood; the interface between the driver's cab hood 20 and the front wall component 11 and the rear wall component 12 is a two-dimensional curved surface.

[0106] The driver's cab steel structure 10 provides installation interfaces for both movable and fixed windows. These interfaces are distributed across the driver's cab hood 20 and the driver's cab steel structure 10. This means that the installation interfaces are entirely provided by both the driver's cab hood 20 and the driver's cab steel structure 10, preventing any component interface from crossing the seam between the driver's cab steel structure 10 and the driver's cab hood 20, thus avoiding installation difficulties. Specifically, the driver's cab steel structure 10 includes a front wall assembly 11, a rear wall assembly 12, a waist beam assembly 14, a roof curved beam assembly 18, and two side wall assemblies 13 arranged laterally opposite each other. The waist beam assembly 14 connects the front wall assembly 11 and the side wall assembly 13. The side wall assembly 13 connects the front wall assembly 11 and the rear wall assembly 12 longitudinally, and has installation interfaces for both movable and fixed windows.

[0109] In this embodiment, the front wall assembly 11 includes a front wall 111 and an opening and closing mechanism located at the front end of the front wall 111. The front end, as described here and below, is based on the running direction of the rail vehicle, with the longitudinal direction being the length direction of the rail vehicle and the transverse direction being the width direction of the rail vehicle. The front wall assembly 11 is located at the end of the driver's cab steel structure 10, connected to the underframe and side wall assembly 13, and provides relevant installation interfaces for the opening and closing mechanism, head cover, electric whistle / wind whistle, brake lines, etc.

[0110] Among them, the front wall component 11 includes a front wall 111, and the front wall 111 includes:

[0111] The front wall main board 1111 has a reinforced plate beam structure 1112 on the inner panel facing the driver's cab.

[0112] The front wall reinforcement plate 1113 is set along the outer contour of the front wall main plate 1111 and is used to connect with the driver's cab head cover 20 and the side wall assembly 13; the thickness of the front wall reinforcement plate 1113 is greater than the thickness of the front wall main plate 1111.

[0113] Since the opening and closing mechanism and the head cover are heavier than other installation components, in order to ensure the installation reliability of the opening and closing mechanism and the head cover, a front wall reinforcement plate 1113 is set in the outer contour area of ​​the front wall main board 1111. The outer contour of the front wall reinforcement plate 1113 matches the top contour of the joint position of the driver's cab head cover 20. The inner contour of the front wall reinforcement plate 1113 is set according to the principle of lightweighting (minimum area) of the connection point of the head cover and the opening and closing mechanism to achieve lightweighting. The thickness of the front wall reinforcement plate 1113 is greater than that of the front wall main plate 1111. The front wall main plate 1111 is 2-4mm thick, preferably 2mm, and the thickness of the front wall reinforcement plate 1113 is 8-12mm thick, preferably 10mm. On the driver's side, the front wall reinforcement plate 1113 protrudes beyond the front wall main plate 1111a by a certain dimension, and on the driver's side, the front wall reinforcement plate 1113 protrudes beyond the front wall main plate 1111b by a certain dimension. A brake line installation interface 1114 and an electric horn and windhorn installation interface 1115 are respectively provided on the outer plate surface of the front wall main plate 1111 for installing brake lines, electric horns, and windhorns respectively. Two brake line installation interfaces 1114 and two electric horn and windhorn installation interfaces 1115 are provided, symmetrically arranged along the transverse center line of the front wall component 11. The brake line installation interface 1114 and the electric horn and windhorn installation interface 1115 are respectively provided as mounting seats with flanged wing plates. To ensure the strength and rigidity of the front wall component 11, a reinforced plate-beam structure 1112 is provided on the inner panel of the front wall main board 1111 facing the driver's cab. The plate-beam structure 1112 includes several intersecting front wall horizontal beams 11121 and front wall longitudinal beams 11122, as well as transverse reinforcing beams 11123. The brake line installation interface 1114 and the electric horn and windhorn installation interface 1115 are respectively located on the outer panel of the front wall main board 1111 at the intersection points of the plate-beam structure 1112 on the inner panel. The plate-beam structure 1112 provides support for each installation interface, thereby preventing electric... The whistle / baghorn and brake lines deform after welding; the front wall crossbeam 11121 and the front wall longitudinal beam 11122 can be set as L-shaped angle irons, each L-shaped angle iron including a first face 111211 and a second face 111212 that are perpendicular to each other. The first face 111211 is attached to the front wall main board 1111, and the second face 111212 is perpendicular to the front wall main board 1111. The first face 111211 and the second face 111212 of the front wall crossbeam 11121 and the front wall longitudinal beam 11122 are continuously set at the intersection; thus, the lateral load and longitudinal load at the intersection can be continuously transmitted.Taking the example of four longitudinal beams 11122 and two sets of three crossbeams 11121 on the front wall, the top of the longitudinal beams 11122 is close to the front wall reinforcement plate 1113 to ensure the transmission of longitudinal load, while allowing for adjustment, such as a gap of 1.5-3.5mm. At the intersection of the crossbeams 11121 and the longitudinal beams 11122, the second surface 111212 of the crossbeams 11121 extends laterally to the top of the first surface 111211 of the longitudinal beams 11122 and abuts against and is welded to the second surface 111212 of the longitudinal beams 11122. The first surface 111211 of the crossbeams 11121 extends laterally to the edge of the second surface 111212 of the longitudinal beams 11122 and abuts against and is welded to the crossbeams 11122. The L-shaped angle iron openings of the two sets of crossbeams 11121 are arranged opposite each other to further improve the connection strength. The transverse reinforcing beam 11123 is located at the bottom of the front wall main plate 1111 and extends along the length of the front wall main plate 1111. It is used to connect with the base frame and prevent deformation after the front wall reinforcing plate 1113 is assembled and welded with the interface outside the driver's cab, and to prevent deformation after the front wall assembly 11 is welded. It can be understood that the transverse reinforcing beam 11123 also has adjustment allowances at both ends, such as a gap of 1.5-3.5mm. The transverse reinforcing beam 11123 with low rigidity is set on the inner plate of the front wall 111 to cooperate with the base frame, and process adjustment allowances are set at the transverse reinforcing beam 11123 to ensure the overall outline and dimensions of the driver's cab assembly, and can simultaneously achieve load and shape, and can achieve lightweight design of the driver's cab.

[0114] The front wall reinforcement plate 1113 is set along the outer contour of the front wall main plate 1111. An opening / closing mechanism mounting interface 11131 and a headgear mounting interface 11132 are respectively provided on the front wall reinforcement plate 1113. The opening / closing mechanism mounting interfaces 11131 are set in two sets, each set including two opening / closing mechanism mounting interfaces 11131. The two sets of opening / closing mechanism mounting interfaces 11131 are symmetrically arranged on both sides of the transverse centerline of the front wall component 11. The opening / closing mechanism mounting interface can be set as a mounting base; the headgear mounting interface 11132 can be set as an oblong hole to provide installation adjustment range. The front wall 111 and the opening / closing mechanism are sealed with adhesive (mechanical connection, sealing). The outer contour of the front wall 111 is recessed compared to the outer contour of the opening / closing mechanism to reserve space for adhesive application; the front wall reinforcement plate 1113 provides support for adhesive application.

[0115] The driver's cab steel structure 10 provided in this application also includes an energy-absorbing beam 15, anti-collision posts 16, and anti-collision corner posts 17; the waist beam assembly 14 includes a transverse waist beam 141 and a longitudinal waist beam 142, with the transverse waist beam 141 located below the front window frame of the driver's cab; the longitudinal waist beam 142 is located below the side wall window; the front wall assembly 11, waist beam assembly 14, energy-absorbing beam 15, anti-collision posts 16, and anti-collision corner posts 17 form an energy-absorbing zone to ensure the driver's safety; the anti-collision posts 16, anti-collision corner posts 17, transverse waist beam 141, and longitudinal waist beam 142 form a protective belt to further protect the driver's personal safety.

[0116] Specifically, one end of the energy-absorbing beam 15 is fixedly connected to the front wall 111 along its length, and the other end of the energy-absorbing beam 15 is fixedly connected to the anti-collision post 16 along its length; the anti-collision post 16 and the energy-absorbing beam 15 are set in a one-to-one correspondence; the anti-collision post 16 and the anti-collision corner post 17 are both fixed below the transverse waist beam 141, and the anti-collision corner post 17 is located on the outside of the anti-collision post 16 along the transverse direction.

[0117] One end of the energy-absorbing beam 15 along its length is connected to the front wall reinforcement plate 1113, and preferably faces the installation interface of the opening and closing structure. The other end of the energy-absorbing beam 15 along its length is welded to the anti-collision post 16. Both the anti-collision post 16 and the anti-corner post are box beam structures. In the transverse direction of the driver's cab, the anti-collision corner post 17 is located transversely outside the anti-collision post 16. Optionally, there are two energy-absorbing beams 15, two anti-collision posts 16, and two anti-collision corner posts 17. To ensure the structural reliability and lightweight design of the aforementioned protective strips, several vertically arranged transverse stiffeners 161 are installed inside the crash posts 16 and corner posts 17, with the transverse stiffeners 161 in the same row of each crash post 16 and corner post 17 lying on the same horizontal plane. Taking the example of four transverse stiffeners 161 each for the crash posts 16 and corner posts 17, the first row of transverse stiffeners 161 of the crash posts 16 and the first row of transverse stiffeners 161 of the corner posts 17 are on the same horizontal plane, the second row of transverse stiffeners 161 of the crash posts 16 and the second row of transverse stiffeners 161 of the corner posts 17 are on the same horizontal plane, and so on.

[0118] To further ensure the structural reliability of the protective belt, the transverse waist beam 141 is provided with vertical stiffeners 1411 corresponding to the transverse side plates of the anti-collision posts 16 and anti-collision corner posts 17. Several vertical stiffeners 1411 are provided in the length direction of the transverse waist beam 141. Each anti-collision post 16 has two vertical stiffeners 1411 respectively on its two transverse side plates. Similarly, each anti-collision corner post 17 has two vertical stiffeners 1411 respectively on its two transverse side plates to improve the connection strength and ensure the continuous transmission of load.

[0119] Meanwhile, since the bottom is the first to collide when a collision occurs, and the bottom bears a larger load, a connecting stiffener 162 is provided between the bottoms of the adjacent anti-collision posts 16 and anti-collision corner posts 17 to facilitate the stability of the structure and the transfer of load.

[0122] The side wall component 13 of this application provides an installation interface for corner windows, side windows, and the driver's cab. The side wall component 13 includes a side wall frame 131 and a side wall skin 132 located outside the side wall frame 131. The inner contours of the side wall frame 131 and the side wall skin 132 match. The skin needs to have good deformation capacity and a certain rigidity. Therefore, the thickness of the plate is relatively thin, generally 2 to 3 mm. The side wall frame 131 plays the role of transmitting loads, and the skin plays the role of shaping and providing installation interfaces. Therefore, the thickness of the plate is relatively thicker than that of the skin.

[0123] Optionally, the side wall frame 131 includes a side wall curved beam 1311 and an end column 1312. The side wall curved beam 1311 extends longitudinally and its height gradually increases from front to back. With the direction of the front of the rail vehicle as the front, the front end of the side wall curved beam 1311 is connected to the front wall reinforcement plate 1113 to realize the connection between the side wall component 13 and the front wall component 11. The end column 1312 is located at the longitudinal rear end of the side wall curved beam 1311 and is arranged in the vertical direction. The end column 1312 is used to connect the rear wall component 12. The longitudinal waist beam 142 of the waist beam component 14 is located below the side wall window. The longitudinal front end of the longitudinal waist beam 142 is fixed to the side wall curved beam 1311, and the longitudinal rear end of the longitudinal waist beam 142 is perpendicular to and fixed to the end column 1312. The upper and lower planes of the longitudinal waist beam 142 are parallel to the rail surface and can be used as a positioning reference in the vehicle height direction. The longitudinal end faces of the end column 1312 are perpendicular to the rail surface and can be used as a positioning reference in the vehicle length direction when assembling the driver's cab side wall 13 and the driver's cab. Together with the longitudinal waist beam 142, they form the reference for manufacturing side windows and corner windows, which helps to ensure the manufacturing error of the side window and corner window frames. Preferably, the end column 1312 is a U-shaped column.

[0124] Furthermore, the sidewall frame 131 also includes:

[0125] Several longitudinally arranged support beams 1313, the top of the first longitudinal support beam 1313 is fixed to the side wall curved beam 1311, the top of the remaining support beams 1313 other than the first support beam 1313 is fixed to the longitudinal waist beam 142, and the bottom of the support beams 1313 is used to fix to the base frame.

[0126] The side wall curved beam 1311 below the longitudinal waist beam 142, the first support beam 1313 along the longitudinal direction, and the longitudinal waist beam 142 form the first side wall area, and a number of intersecting grid beam structures 1314 are provided in the first side wall area.

[0127] The longitudinal waist beam 142, the first longitudinal support beam 1313 below the longitudinal waist beam 142 and the end column 1312 form the second side wall area;

[0128] The side wall curved beam 1311 above the longitudinal waist beam 142, the first longitudinal support beam 1313, the longitudinal waist beam 142 and the end column 1312 form the third side wall area, which is used to install corner windows and side windows.

[0129] The first support beam 1313, arranged longitudinally from front to back, is divided into upper and lower parts by the longitudinal waist beam 142. The top of the upper part of the first support beam 1313 is fixed to the side wall curved beam 1311, and the bottom of the upper part of the first support beam 1313 is fixed to the upper surface of the longitudinal waist beam 142. The top of the lower part of the first support beam 1313 is fixed to the lower surface of the longitudinal waist beam 142, and the bottom of the lower part of the first support beam 1313 is fixed to the base frame. The tops of the remaining support beams 1313 are fixed to the lower surface of the longitudinal waist beam 142, and the bottoms of the remaining support beams 1313 are fixed to the base frame. The support beams are configured as a U-shaped structure, as shown in Figure 19.

[0130] The first side wall area consists of a longitudinal waist beam 142, a side wall curved beam 1311 below the longitudinal waist beam 142, and the lower part of the first support beam 1313. Located outside the driver's cab safety area, this first side wall area provides an interface for the installation of the hood, and the curvature of the side wall skin 132 in this area varies considerably. Therefore, the perimeter of the side wall frame 131 in this area (except for the open structure at the bottom connection with the base frame) adopts a U-shaped frame with high rigidity. Several intersecting grid beam structures 1314 are provided within the first side wall area, using an orthogonal grid beam structure, i.e., a relatively thin, dense, and short longitudinal and transverse grid beam structure 1314. This facilitates shaping while ensuring strength and rigidity. The thickness of the orthogonal grid beams in this area is 3mm, and the spacing between the orthogonal grid beams is between 200 and 300mm. The front ends of some of the crossbeams and side wall curved beams 1311 of the grid beam structure 1314 are fixed to the front wall reinforcement plate 1113. The grid beams are made of L-shaped or U-shaped angle irons and are fixed to the front wall reinforcement plate 1113 of the driver's cab in an open structure to increase stability and reduce noise.

[0131] The second side wall area consists of a longitudinal waist beam 142, the lower part of the first support beam 1313, and end columns 1312, forming a box-shaped stable structure for load transfer; the side wall frame 131 also includes:

[0132] Several transverse reinforcing beams 1317 are located between adjacent support beams 1313, support beams 1313 and end columns 1312, respectively. The transverse reinforcing beams 1317 are used to support the side wall skin 132.

[0133] A reinforcing plate 1318 is provided below any support beam 1313, and the support beam 1313 is fixed to the base frame via the reinforcing plate 1318.

[0134] Similar to the first side wall area, the bottom of the second side wall area is an open structure. Due to the relatively small curvature change in this area, and considering shape retention and weight reduction requirements, transverse reinforcing beams 1317 are used to support the side wall skin 132 between each supporting beam 1313. The interval between each supporting beam 1313 is set at 600-700mm to meet shape retention and weight reduction requirements, and the transverse reinforcing beams 1317 are set at a vertical interval of 250-300mm. Specifically, several transverse reinforcing beams 1317 are located between adjacent supporting beams 1313, between supporting beams 1313 and end columns 1312; simultaneously, a reinforcing plate 1318 is provided below each supporting beam 1313, and the supporting beam 1313 is fixed to the base frame via the reinforcing plate 1318 to reduce stress concentration. The transverse reinforcing beams 1317 are set as L-shaped angle irons.

[0135] Furthermore, the side wall frame 131 also includes several side wall reinforcement plates 1319, located at the longitudinal front end of the grid beam structure 1314, specifically set within the front grid of the grid beam structure 1314; the side wall curved beam 1311 and some of the side wall reinforcement plates 1319 are fixed to the front wall assembly 11. Before the front open structure of the front wall assembly 11 is connected to the front wall reinforcement plate 1113, the side wall reinforcement plates 1319 are welded first. The side wall reinforcement plates 1319 and the front wall reinforcement plate 1113 in the outer contour area of ​​the front wall assembly 11 constitute the bonding area between the opening and closing mechanism and the driver's cab; at the same time, the surface quality control of the side wall shape is further improved, the stability of the structure is enhanced, and vibration and noise are reduced.

[0136] Considering manufacturing costs and processability, the sidewalls are typically constructed by welding multiple sidewall skins 132 to a sidewall frame 131. To control deformation of the sidewall skins 132 after welding, the dividing lines between the multiple sidewalls are set on a supported frame, such as longitudinal waist beams 142 or support beams 1313. Simultaneously, corresponding support plates 13131 can be installed on the support beams to enhance support for the sidewall skins, as shown in Figure 18.

[0137] The third side wall area provides installation interfaces for corner windows and side windows, specifically including corner window installation interface 1315 and side window installation interface 1316; the top provides an interface for hood installation. The structural design of this area should facilitate the installation of corner windows, side windows, and hoods, reducing error accumulation. The first, second, and third side wall areas are formed by integral components such as longitudinal waist beam 142 and end columns 1312, which helps reduce manufacturing errors in the connection between the second and third side wall areas. The two sides of the U-shaped beam of the end column 1312 are perpendicular to the rail surface and can be used as a positioning reference in the vehicle length direction when assembling the driver's cab side wall 13 and the driver's cab. The upper and lower planes of the longitudinal waist beam 142 (which are parallel to the rail surface) can be used as a positioning reference in the vehicle height direction of the third side wall area, forming a reference for the manufacturing of side windows and corner windows together with the end column 1312, thus helping to ensure the manufacturing error of the side window and corner window frames. The upper sidewall curved beam 1311 of the third sidewall area provides an interface for the headgear installation, and is designed in sections with the longitudinal waist beam 142 and the sidewall curved beam 1311 of the first sidewall area. The design of the beams and columns inside the first sidewall area needs to take into account the load transfer and distribution near the front of the vehicle. The beam row design is consistent with the U-shaped beam row section at the corresponding position in the first sidewall area; the beam row between the corner windows and side windows is designed to take into account the outline of the corner windows and side windows.

[0138] The side wall component 13 is a curved component, using the end column 1312 as the reference for the vehicle length direction and the longitudinal waist beam 142 as the reference for the side wall height direction. This reduces the accumulation of manufacturing errors after the installation of corner windows and side windows, facilitating the subsequent installation of interior trim, corner windows, side windows, and the driver's cab, and saving on assembly and repair work. The end column 1312 is a U-shaped column, with its outer contour matching the side wall skin of the driver's cab, providing good rigidity and resistance to deformation, which helps to ensure the outline of the driver's cab after the side wall component 13 is connected to the rear wall. Stiffeners are installed at the corresponding positions of the end column 1312, the side wall curved beam 1311, and the longitudinal waist beam 142 to facilitate load transfer.

[0139] Example 3

[0140] As shown in Figures 25-28, Figure 25 is a structural schematic diagram of the rear wall provided in the embodiment of this application; Figure 26 is a partial enlarged structural schematic diagram of the top curved beam provided in the embodiment of this application; Figure 27 is a schematic diagram of the assembly structure of the driver's cab headgear and end columns provided in the embodiment of this application; Figure 28 is a schematic diagram of the assembly structure of the end columns and passenger compartment provided in the embodiment of this application.

[0141] The rear wall assembly 12 provided in this application is a planar structure used to connect the driver's cab and the passenger compartment. The rear wall assembly 12 includes a top curved beam 121 and a rear wall frame 122. The top curved beam 121 spans across the rear wall frame 122 laterally, and the bottom surfaces of both ends of the top curved beam 121 rest on the top surface of the end column 1312. The top curved beam 121 is used to connect the driver's cab hood 20 and the passenger compartment roof structure. The top curved beam 121 is welded and fixed to the rear wall frame 122. The top curved beam 121 also provides a connection interface for the driver's cab hood 20 and the passenger compartment roof structure, and connects to the end column 1312 of the side wall. To facilitate measurement and assembly positioning during driver's cab assembly, the interface between the top curved beam 121 and the end column 1312 is parallel to the rail surface.

[0142] Optionally, the rear wall frame 122 includes:

[0143] The centerline of the rear wall door frame 123 coincides with or is parallel to the transverse centerline of the driver's cab steel structure 10; the bottom of the rear wall door frame 123 is used to connect with the base frame.

[0144] Several rear wall beams 124, and the door frame columns on both sides of the rear wall door frame 123 are connected to the end columns 1312 via several rear wall beams 124.

[0145] The rear wall door frame 123 has two door frame columns arranged laterally opposite each other, and the bottom of the rear wall door frame 123 is used to connect with the base frame. The rear wall crossbeam 124 is preferably set as an L-shaped angle iron or a U-shaped angle iron, which has an open structure during the rear wall construction to provide process allowance. This ensures the installation accuracy of the door frame structure and facilitates the connection between the driver's cab side wall and the rear wall 12. The length of the rear wall crossbeam 124 can be adjusted to ensure the overall outline accuracy requirements of the driver's cab. Similarly, the bottom column of the rear wall door frame 123 is also set as an open structure, such as an L-shaped structure or a U-shaped structure. The open structure is used to connect with the base frame floor surface, which reduces the connection area and facilitates the adjustment of the height dimension.

[0146] Optionally, the top curved beam 121 is provided with a head cover end interface 1211 at one end along the longitudinal direction toward the driver's cab head cover 20;

[0147] And / or, the top surface of the top curved beam 121 is provided with a passenger compartment top area interface 1212 on the side of the top surface near the passenger compartment.

[0148] The end interface 1211 of the head cover has a stepped structure, and the end of the driver's cab head cover 20 is also set with a stepped structure to achieve docking and fixation by adhesive bonding. The top surface of the top curved beam 121 is provided with a passenger compartment top area interface 1212, which can be set as a groove to overlap with the passenger compartment top area, specifically the passenger compartment skin. It can be understood that after the driver's cab is assembled, the passenger compartment roof skin overlaps on the top curved beam 121 to ensure welding quality and the airtightness of the entire vehicle. The passenger compartment roof assembly is the last component assembled during the vehicle body assembly. After ensuring the airtightness of the roof skin and the rear wall of the driver's cab, in order to reduce repair and adjustment work, a connecting plate is set between the passenger compartment roof frame and the top curved beam 121 of the rear wall of the driver's cab to adjust the manufacturing error during vehicle body assembly and ensure the vehicle body length.

[0149] Meanwhile, in order to connect the end column 1312 with the passenger compartment and the driver's cab, the end column 1312 is provided with an installation flange 13121 extending towards the passenger compartment side in the longitudinal direction, and the connection seam of the side wall skin 21132 of the passenger compartment and the side wall skin 132 of the driver's cab is connected to the installation flange 13121.

[0150] The side wall frame 22 of the guest room extends longitudinally to the inner surface where the flange 13121 is installed and connects with the longitudinal end wall of the end column 1312.

[0151] The mounting flange 13121 can be specifically an L-shaped angle iron. One side of the L-shaped angle iron fits against the longitudinal end wall of the end column 1312, and the other side of the L-shaped angle iron extends longitudinally towards the passenger compartment. The connection seam between the passenger compartment side wall skin 21 and the driver's cab side wall skin 132 overlaps on the mounting flange 13121. The end column 1312 simultaneously provides support for both the passenger compartment side wall skin 132 and the driver's cab side wall skin 132, ensuring welding quality and the airtightness of the entire vehicle. The end column 1312 of the passenger compartment frame and the driver's cab side wall 13 is connected through the reserved process adjustment amount of the passenger compartment frame to ensure the length of the vehicle body. The passenger compartment side wall skin 132 and the driver's cab end column 1312, and the passenger compartment roof skin and the top curved beam 121 adopt an overlapping structure, which helps to ensure welding quality, dimensional accuracy after vehicle body assembly, and the airtightness of the entire vehicle.

[0152] In one specific embodiment, after the driver's cab is assembled, its structure with the underframe includes the interface between the front wall assembly 11 and the underframe, the interface between the side wall assembly 13 and the underframe, and the interface between the rear wall assembly 12 and the underframe. Because the overall rigidity of the underframe is relatively high, a transverse reinforcing beam 11123 with lower rigidity is installed on the inner side of the front wall of the driver's cab for connection, ensuring the dimensional accuracy and airtightness of the assembled vehicle body. The side wall frame 131 is connected to the underframe plane via an open support beam 1313, and the side wall skin 132 overlaps the support beam 1313, ensuring not only an aesthetically pleasing appearance after welding but also the airtightness of the entire vehicle.

[0153] The aforementioned driver's cab is suitable for vehicles with carbon steel bodies and structures requiring significant interior space. It combines a bottom driver's cab steel structure 10 with an upper driver's cab headliner 20. The bottom driver's cab steel structure 10 is composed of a carbon steel metal frame and skin, providing load-bearing capacity and shape stability to ensure driver safety. It also provides installation interfaces for driver's cab equipment such as side windows and operable windows, reducing the space occupied within the cab and ensuring convenient operating space. The reduced size of the driver's cab steel structure 10 helps lower the manufacturing costs of molds, gauges, and bending parts, improving economic efficiency and achieving lightweight design.

[0154] The upper driver's cab hood 20 adopts a fiberglass sandwich structure that facilitates curved surface design, providing three-dimensional interfaces for the windshield, external lighting, headlight glass, etc. This achieves both lightweight design and reduced manufacturing costs. Furthermore, the fiberglass composite material manufacturing process improves the dimensional accuracy of three-dimensional components and the control of interface matching. The driver's cab hood 20 is connected by bolts to ensure reliable connection, and a sealant structure is used to seal the driver's cab steel structure 10 to the driver's cab hood 20.

[0155] The connection interfaces between the major modules of the driver's cab, including the front wall component 11, the side wall component 13, and the rear wall component 12, adopt a connection structure with high stiffness matching low stiffness. In addition, process adjustment is set in the area with low stiffness, which helps to ensure the overall outline and dimensions of the driver's cab after assembly.

[0156] The design of the connection interfaces between the front wall, side wall, and rear wall of the driver's cab during its assembly, as well as the interface relationship design between the driver's cab steel structure 10 and the passenger compartment underframe, side wall, and roof, can reduce the amount of assembly and repair work, control post-weld deformation, and ensure the dimensional accuracy and sealing of the entire vehicle.
