Description

Technical Field

[0001] This application relates to the technical field of transport carriages, and more particularly to the body structure of a mine-use modular trackless carriage. Background Technology

[0002] Trackless mining carriages, as a core component of mining transportation equipment, are essential structural carriers for transporting personnel and materials. In the mining environment, trackless carriages must possess high reliability, strong adaptability, and good safety, capable of withstanding loads and vibrations under complex working conditions. As a key component of trackless rubber-tired mining vehicles, the carriage not only carries people and goods but also directly affects the overall stability, safety performance, and service life of the vehicle. In the mining production process, the rational design and optimization of the carriage structure is of great significance for improving transportation efficiency, ensuring the safety of workers, and reducing maintenance costs. With increasing mining depth and the increasing complexity of the working environment, higher requirements are placed on the structural strength, space utilization, comfort, and explosion-proof performance of the carriage, making it an indispensable structural unit in mining transportation equipment.

[0003] Currently, trackless mining carriages on the market mainly adopt two structural forms: a chassis-carriage separation structure and a chassis-carriage fixed connection structure. The chassis-carriage separation structure allows for interchangeability of different superstructure units on the same chassis, with the carriage serving as one of the superstructure units, which can be flexibly replaced according to actual transportation needs. The advantage of this structure is that the carriage can be flexibly adjusted according to the number of passengers. According to relevant safety standards, the number of passengers in a carriage is generally limited to no more than 25. This flexible configuration greatly improves the economy and applicability of the equipment, meeting the transportation needs of different mines and different operating scenarios. The chassis-carriage fixed connection structure, on the other hand, connects and fixes the chassis and carriage as a single unit before leaving the factory, making them inseparable. While this structure is simple, it lacks flexibility, cannot replace the carriage according to actual needs, resulting in limited applicability of the equipment. Furthermore, maintenance and replacement require a complete replacement, increasing operating costs.

[0004] However, existing car body structures still suffer from significant manufacturing defects. Particularly due to the large volume and space of the car body, multiple assembly components need to be produced during manufacturing, making it difficult to guarantee the consistency of precision among these components. During unified assembly, the excessive number of connecting parts and endpoints on each component easily leads to structural instability due to dimensional differences, and may even prevent the assembly process from being completed smoothly. This problem not only increases production difficulty and cost but also affects the quality and reliability of the final product. Furthermore, excessive connection points increase the complexity of later maintenance and reduce the equipment's lifespan. Especially in the production of trackless rubber-tired mining vehicles, the car body, as a critical structural component, directly affects the safety performance of the entire machine. Therefore, the design of the car body components urgently needs optimization. By reducing the number of components and connection points in the assembly process, the assembly process can be simplified, and the consistency of assembly precision can be improved.

[0016] Compared with existing technologies, the prefabricated trackless mining car body structure proposed in the above technical solution significantly reduces the number of connection points in the assembly process by decomposing the car body into at least four independent prefabricated components. This simplifies the assembly process from requiring dozens or even hundreds of connection points in traditional cars to requiring only a few, avoiding assembly instability caused by size differences and significantly reducing rework rates due to assembly accuracy issues, making the car body assembly process more reliable and efficient. The technical solution of this application achieves modular and standardized production of the car body. Each car body component can be manufactured in parallel and precisely inspected on an independent production line, effectively solving the problem of accuracy consistency caused by the collaborative production of multiple components in traditional manufacturing methods. By simplifying the car body structure into four core prefabricated components, the manufacturing accuracy of each component can be independently controlled, avoiding dimensional deviations caused by cumulative errors in traditional overall manufacturing, ensuring the final assembled car body structure has accurate dimensions and reliable strength. At the same time, the modular design shortens the production cycle and reduces manufacturing costs, providing an efficient and feasible solution for the large-scale production of trackless rubber-tired mining cars. Not only has the manufacturing process been simplified, but the overall performance and reliability of the carriages have also been significantly improved. Furthermore, the modular design makes maintenance and replacement of the carriages more convenient, extending their service life.

[0046] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0047] Reference Figure 1 As shown, an embodiment of this application proposes a body structure for a mine-use prefabricated trackless car. The body structure of the mine-use prefabricated trackless car may include: a first body component 1, having a first enclosed accommodating space, and wheel arch plates 15 on both sides of the first body component 1, the wheel arch plates 15 being used to form a clearance space for wheel rotation at the bottom of the first body component 1; a second body component 2, having a second enclosed accommodating space, and the second body component 2 being connected to the first body component 1 to connect the second accommodating space with the first accommodating space; a third body component 3, having a third enclosed accommodating space, and the third body component 3 being connected to the side of the first body component 1 away from the second body component 2, and connecting the third accommodating space with the second accommodating space through the first accommodating space; and a top component 5, covering the top of the first body component 1, the second body component 2 and the third body component 3, together forming a hollow rectangular body.

[0048] Specifically, in the technical solution adopted in this application, the first compartment component 1, the second compartment component 2, the third compartment component 3, and the roof component 5 are all independent prefabricated components. The first compartment component 1 constitutes the central main body of the carriage, and the second compartment component 2 and the third compartment component 3 serve as the head and tail of the carriage, respectively, and are fixed to both ends of the first compartment component 1 by welding or bolting. By aligning and connecting the internal spaces of the first compartment component 1, the second compartment component 2, and the third compartment component 3, i.e., the first accommodating space, the second accommodating space, and the third accommodating space, and then assembling them with the roof component 5, a structurally regular hollow rectangular carriage can be quickly assembled. This modular design allows each core component to be produced and inspected in parallel and separately during the manufacturing stage, and then finally assembled. This not only greatly simplifies the final on-site assembly steps and shortens the manufacturing cycle, but more importantly, through modular manufacturing and precision control, it can effectively avoid dimensional differences and fit problems caused by cumulative errors in traditional integral manufacturing or complex assembly, ensuring the dimensional accuracy and structural strength of the final body structure.

[0049] Furthermore, refer to Figures 2 to 4 As shown, in some embodiments, the first body component 1 includes: a first bottom plate 11 and two first side panels 12; the two first side panels 12 are arranged opposite to each other along the length direction of the first bottom plate 11 and are connected to the top surface of the first bottom plate 11 through wheel arch plates 15, thereby forming a U-shaped structure together with the first bottom plate 11.

[0050] Specifically, in the technical solution adopted in this application, the first compartment component 1 has at least two implementation methods: In the first implementation method, two first compartment panels 12 are indirectly connected to the top surface of the first bottom plate 11 through wheel arch plates 15, and the two first compartment panels 12, wheel arch plates 15, and the first bottom plate 11 together form a U-shaped structure; in the second implementation method, the two first compartment panels 12 are directly connected to the first bottom plate 11, together forming a U-shaped structure, while the wheel arch plates 15 are disposed at the bottom of the first bottom plate 11. The two opposing first compartment panels 12 form a first accommodating space with openings on both sides above the first bottom plate 11.

[0051] In terms of manufacturing, the first compartment component 1 can be manufactured as a whole using an integral molding process, or the two first compartment panels 12, wheel arch panels 15 and the first bottom plate 11 can be manufactured separately and then connected to each other by welding to form the first compartment component 1; other applicable manufacturing processes can also be used, as long as the production and assembly of the first compartment component 1 as an independent prefabricated unit can be achieved.

[0052] Furthermore, refer to Figure 3 , Figure 4 and Figure 7As shown, in some embodiments, the first compartment component 1 further includes: multiple first support beams 13 connected to two first compartment panels 12 and extending along the height direction of the two first compartment panels 12; a first support body 14 connected to the top surface of the first bottom plate 11, and the two ends of the first support body 14 supported on the two first compartment panels 12; the top component 5 is provided with multiple transverse support beams 51 arranged along the length direction, and some of the transverse support beams 51 are connected to each of the first support beams 13; the first support beams 13, the first support body 14 and the transverse support beams 51 together form a first reinforcing frame of a rectangular structure.

[0053] Specifically, in the technical solution adopted in this application, the beams of each first support beam 13 can be fixed to the inner walls of the two first side panels 12 by welding, and are vertically arranged along the height direction of the two first side panels 12, so that they can be effectively supported between the first bottom plate 11 and the top component 5, playing the role of transferring and distributing loads. The first support body 14 can be set as a cuboid structure, and is fixed to the top surface of the first bottom plate 11 by integral molding or welding process, and the two ends of the first support body 14 respectively contact and support the inner walls of the two first side panels 12, thereby forming a stable lateral support at the bottom. The top component 5 adopts a straight plate structure, which is not only used to close the top of the car body, but also has multiple transverse support beams 51 arranged on its lower surface. Each transverse support beam 51 enhances the bending stiffness of the top component 5 itself, and some transverse support beams 51 are also integrated with the skeleton of the first car body component 1 by connecting to the top of the first support beam 13. In an optional connection method, some transverse support beams 51 and each first support beam 13 can be fixedly connected by welding process or bolt fasteners. Thus, the first reinforcing frame, which is formed by the first supporting beam 13, the first supporting body 14 and part of the transverse supporting beam 51, forms a spatial support frame on the inner side of the two first box panels 12, the first bottom plate 11 and the box roof component 5. This can effectively improve the resistance to falling object impact and rolling impact of the first box component 1 and the box roof component 5 under harsh working conditions, ensure the integrity and safety of the overall structure, and thus significantly enhance the overall rigidity and load-bearing capacity of the first box component 1.

[0054] In some embodiments, the first support beam 13 is a hollow square beam structure to further meet the lightweight requirements of the box structure. After the first panel 12 is connected to the first bottom plate 11, the lengths of the two first side edges 121 adjacent to the first bottom plate 11 on the first panel 12 are set to match the lengths of the first support beam 13, and the first side edges 121 are inwardly bent on the first panel 12. This can be understood as the two first side edges 121 bending inward based on the first panel 12. The first support beams 13 are arranged in pairs, for example, four first support beams 13 are set, with the beam bodies of two first support beams 13 connected to the first side edges 121 and the corresponding first panels 12, thereby making the first support beams... The two sides of the first support beam 13 are in contact with the first panel 12, which not only enhances the connection strength between the first support beam 13 and the first panel 12, but also indirectly increases the thickness of the first support beam 13 through the first side 121, so as to improve the supporting force of the first support beam 13 on the top component 5. In this embodiment, the number of first support beams 13 can be six or more, and each first support beam 13 is arranged along the width direction of the first panel 12, wherein the two outermost first support beams 13 are attached to the first side 121 and connected to the first panel 12.

[0055] In a further embodiment, the second side 122 of the first panel 12 facing away from the first bottom plate 11 can be lengthened. When the top component 5 covers the first body component 1 and is supported by the first support beams 13 and the four first side 121, the second side 122 can apply a lateral limiting to the top component 5 along the layout direction of the two first panels 12. That is, the second side 122 on the two first panels 12 can cover both sides of the top component 5. Thus, after the top component 5 is connected to the first support beams 13 by a portion of the lateral support beams 51, this connection method can further improve the rollover impact resistance of the first body component 1 and the top component 5.

[0056] In one embodiment, the first support 14 can adopt a hollow rectangular frame structure, which can meet the requirements of lightweight design while ensuring sufficient load-bearing strength. In addition, the top surface of the first support 14 can also serve as a base for installing seats, making it easier to fix the passenger seats inside the first body component 1, thus achieving the dual functions of structural and practical purposes.

[0057] Furthermore, refer to Figures 2 to 5 As shown, in some embodiments, the second compartment component 2 includes: a second bottom plate 21 and a second compartment panel 22; the second bottom plate 21 is connected to the first bottom plate 11 and is located on the same side of the two first compartment panels 12; the second compartment panel 22 is bent into a U-shaped structure and connected to the top surface of the second bottom plate 21, and the first opening end on the second compartment panel 22 faces the two first compartment panels 12.

[0058] Specifically, in the technical solution adopted in this application, the second panel 22 of the U-shaped structure is connected to the top surface of the second bottom plate 21 to form a second accommodating space with an opening on one side above the second bottom plate 21. The second bottom plate 21 is connected to the first bottom plate 11 by welding and is located on the same side of the two first panels 12. The first opening end of the second panel 22 faces the two first panels 12. This can be understood as the opening of the second panel 22 facing the first accommodating space, so as to connect the second accommodating space with the first accommodating space.

[0059] In terms of manufacturing, the second compartment component 2 can be manufactured as a whole using an integral molding process, or the second compartment panel 22 and the second bottom plate 21 can be manufactured separately and then connected to each other by welding to form the second compartment component 2; other applicable manufacturing processes can also be used, as long as the production and assembly of the second compartment component 2 as an independent prefabricated unit can be achieved.

[0060] Furthermore, refer to Figures 3 to 5 as well as Figure 8 As shown, in some embodiments, the second compartment component 2 further includes: multiple second support beams 23, respectively connected to two opposite bent sidewalls of the second compartment panel 22, and extending along the height direction of the second compartment panel 22; a second support body 24, connected to the top surface of the second bottom plate 21, and the two ends of the second support body 24 are supported on the two opposite bent sidewalls of the second compartment panel 22; the top component 5 is provided with multiple transverse support beams 51 arranged along the length direction, and some of the transverse support beams 51 are connected to each of the second support beams 23; the second support beams 23, the second support body 24 and the transverse support beams 51 together form a second reinforcing frame of a rectangular structure.

[0061] Specifically, in the technical solution adopted in this application, the beams of each second support beam 23 can be fixed to the inner side of the opposite bent sidewall on the second compartment 22 by welding, and are vertically arranged along the height direction of the second compartment 22, so that they can be effectively supported between the second bottom plate 21 and the top component 5, playing the role of transmission and load distribution. The second support body 24 can be set as a cuboid structure, and is fixed to the top surface of the second bottom plate 21 by integral molding or welding process, and the two ends of the second support body 24 respectively contact and support the opposite bent sidewall on the second compartment 22, thereby forming a stable lateral support at the bottom. The straight plate structure of the top component 5 is not only used to close the top of the compartment, but also has multiple transverse support beams 51 arranged on its lower surface. Each transverse support beam 51 enhances the bending stiffness of the top component 5 itself, and some transverse support beams 51 are also integrated with the skeleton of the second compartment component 2 by connecting with the top of the second support beam 23. In one optional connection method, some of the transverse support beams 51 and each of the second support beams 23 can be fixedly connected by welding or bolt fasteners. Thus, the second reinforcing frame, jointly formed by the second support beams 23, the second support body 24, and some of the transverse support beams 51, creates a spatial support frame on the inner side of the second body panel 22, the second floor plate 21, and the roof component 5. This effectively improves the resistance to falling object impacts and rolling impacts of the second body component 2 and the roof component 5 under harsh working conditions, ensuring the integrity and safety of the overall structure, thereby significantly enhancing the overall rigidity and load-bearing capacity of the second body component 2.

[0062] In some embodiments, the second support beam 23 is a hollow square beam structure to further meet the lightweight requirements of the box structure. After the second box panel 22 is connected to the second bottom plate 21, the lengths of the two third sides 221 adjacent to the second bottom plate 21 on the opposite bent sidewalls of the second box panel 22 are set to match the length of the second support beam 23. The third sides 221 are the sides on the first open end of the second box panel 22, and the third sides 221 are inwardly bent on the second box panel 22. It can be understood that the two third sides 221 are bent inward based on the U-shaped structure of the second box panel 22, while the second support beams 23 are paired up, for example, the number of second support beams 23 is set to two, and the beam body of the second support beam 23 is connected to the third side 221 and the second box panel 22. This arrangement allows the two sides of the second support beam 23 to contact the second side panel 22, which not only enhances the connection strength between the second support beam 23 and the second side panel 22, but also indirectly increases the thickness of the second support beam 23 through the third side 221, thereby improving the supporting force of the second support beam 23 on the roof member 5. In this embodiment, the number of second support beams 23 can be four or more, with each second support beam 23 arranged along the width direction of the bent side wall on the second side panel 22. The two second support beams 23 closest to the two third side 221 can be attached to the third side 221 and connected to the second side panel 22.

[0063] In a further embodiment, the fourth side 222 of the second panel 22 facing away from the second bottom plate 21 can be lengthened. When the top member 5 is covered on the second body member 2 and supported by the second support beams 23 and the two third sides 221, since the second panel 22 is set as a U-shaped structure, the fourth side 222 can cover the three sides of the top member 5 and apply lateral restraint. Thus, after the top member 5 is connected to the second support beams 23 by part of the lateral support beams 51, this connection method can further improve the rollover impact resistance of the second body member 2 and the top member 5.

[0064] In one embodiment, the second support 24 can adopt a hollow rectangular frame structure, which can meet the requirements of lightweight design while ensuring sufficient load-bearing strength. In addition, the top surface of the second support 24 can also serve as a base for installing seats, making it easier to fix the passenger seats inside the second body component 2, thus achieving the dual functions of structural and practical purposes.

[0065] Furthermore, refer to Figure 1 and Figure 4 As shown, in some embodiments, two first panels 12 and a second panel 22 are arranged at intervals, thereby forming two first doorway spaces 6 on the side of the rectangular body for installing doors.

[0066] Specifically, in the technical solution adopted in this application, there is no need to use the traditional panel cutting process to create a doorway space on the panel to accommodate the vehicle door. Instead, the space is directly formed by controlling the dimensions during component assembly, which greatly simplifies the processing flow and avoids damage to the structural strength of the body caused by cutting. In this embodiment, the second panel 22 has a U-shaped structure and its first opening end faces the two first panels 12. During the connection process between the first bottom plate 11 and the second bottom plate 21, this embodiment does not require the ends of the two first panels 12 to be directly connected to the edge of the first opening end of the second panel 22. Instead, the relative dimensions and installation spacing of the first panel 12 and the second panel 22 are controlled in advance during the manufacturing stage. After the first bottom plate 11 and the second bottom plate 21 are fixed, the gap that is naturally formed between the two first panels 12 and the second panel 22 is the first doorway space 6 for installing the vehicle door. Because the U-shaped structure of the second panel 22 has two opposing bent sidewalls, with the first opening end of its bent sidewall facing the two first panels 12, a first doorway space 6 is ultimately formed on each of the two opposing sides of the rectangular body, meeting the installation requirements of the double-sided doors. At the same time, the first support beam 13 on the first panel 12 near the second panel 22, and the second support beam 23 on the second panel 22 that is attached to the third side 221, can directly serve as the door frame structure on both sides of the first doorway space 6, without the need for additional door frame components. This ensures the structural strength of the doorway space and further simplifies the assembly process.

[0067] Furthermore, refer to Figure 3 , Figure 4 and Figure 6 As shown, in some embodiments, the third compartment component 3 includes: a third bottom plate 31 and a third compartment plate 32; the third bottom plate 31 is connected to the first bottom plate 11 and is located on the side of the two first compartment plates 12 away from the second compartment component 2; the third compartment plate 32 is bent into a U-shaped structure and connected to the top surface of the third bottom plate 31, and the second opening end on the third compartment plate 32 faces the two first compartment plates 12.

[0068] Specifically, in the technical solution adopted in this application, the U-shaped third panel 32 is connected to the top surface of the third bottom plate 31 to enclose a third accommodating space with an opening on one side above the second bottom plate 21. The third bottom plate 31 is connected to the first bottom plate 11 by welding and is located on the side of the two first panels 12 away from the second panel 22 and the second bottom plate 21. The second opening end of the third panel 32 faces the two first panels 12. This can be understood as the opening of the third panel 32 facing the first accommodating space, so that the third accommodating space is connected to the second accommodating space through the first accommodating space, thereby forming a hollow rectangular box.

[0069] In terms of manufacturing, the third compartment component 3 can be manufactured as a whole using an integral molding process, or the third compartment panel 32 and the third floor panel 31 can be manufactured separately and then connected to each other by welding to form the third compartment component 3; other applicable manufacturing processes can also be used, as long as the production and assembly of the third compartment component 3 as an independent prefabricated unit can be achieved.

[0070] Furthermore, refer to Figure 3 , Figure 4 , Figure 6 and Figure 9 As shown, in some embodiments, the third compartment component 3 further includes: multiple third support beams 33, which are respectively connected to two opposite bent sidewalls of the third compartment panel 32 and extend along the height direction of the third compartment panel 32; a third support body 34, which is connected to the top surface of the third bottom plate 31 and whose two ends are supported on the two opposite bent sidewalls of the third compartment panel 32; multiple transverse support beams 51 arranged along the length direction are provided on the top component 5, and some of the transverse support beams 51 are connected to each of the third support beams 33; the third support beams 33, the third support body 34 and the transverse support beams 51 together form a third reinforcing frame of a rectangular structure.

[0071] Specifically, in the technical solution adopted in this application, the beams of each third support beam 33 can be fixed to the inner side of the opposite bent sidewall on the third compartment 32 by welding, and are vertically arranged along the height direction of the third compartment 32, so that they can be effectively supported between the third bottom plate 31 and the top component 5, playing the role of transmission and load distribution. The third support body 34 can be set as a cuboid structure, and is fixed to the top surface of the third bottom plate 31 by integral molding or welding process, and the two ends of the third support body 34 respectively contact and support the opposite bent sidewall on the third compartment 32, thereby forming a stable lateral support at the bottom. The straight plate structure of the top component 5 is not only used to close the top of the compartment, but also has multiple transverse support beams 51 arranged on its lower surface. Each transverse support beam 51 enhances the bending stiffness of the top component 5 itself, and some transverse support beams 51 are also integrated with the skeleton of the third compartment component 3 by connecting with the top of the third support beam 33. In one optional connection method, some of the transverse support beams 51 and each of the third support beams 33 can be fixedly connected by welding or bolt fasteners. Thus, the third reinforcing frame, jointly formed by the third support beams 33, the third support body 34, and some of the transverse support beams 51, creates a spatial support frame on the inner side of the third body panel 32, the third floor plate 31, and the roof component 5. This effectively improves the resistance to falling object impacts and rolling impacts of the third body component 3 and the roof component 5 under harsh working conditions, ensuring the integrity and safety of the overall structure, thereby significantly enhancing the overall rigidity and load-bearing capacity of the third body component 3.

[0072] In some embodiments, the third support beam 33 is a hollow square beam structure to further meet the lightweight requirements of the box structure. After the third box panel 32 is connected to the third bottom plate 31, the lengths of the two fifth sides 321 adjacent to the third bottom plate 31 on the opposite bent sidewalls of the third box panel 32 are set to match the length of the third support beam 33. The fifth sides 321 are the sides on the first open end of the third box panel 32, and the fifth sides 321 are inwardly bent on the third box panel 32. It can be understood that the two fifth sides 321 are bent inward based on the U-shaped structure of the second box panel 22, while the third support beams 33 are paired up, for example, the number of third support beams 33 is set to two, and the beam body of the third support beam 33 is connected to the fifth side 321 and the second box panel 22. This arrangement allows the two sides of the third support beam 33 to contact the third side panel 32, which not only enhances the connection strength between the third support beam 33 and the third side panel 32, but also indirectly increases the thickness of the third support beam 33 through the fifth side 321, thereby improving the supporting force of the third support beam 33 on the roof member 5. In this embodiment, the number of third support beams 33 can be four or more, with each third support beam 33 arranged along the width direction of the bent side wall on the third side panel 32. The two third support beams 33 closest to the two fifth side panels 321 are attached to the fifth side panels 321 and connected to the third side panel 32.

[0073] In a further embodiment, the sixth side 322 of the third compartment panel 32 away from the third bottom plate 31 can be lengthened. When the top panel 5 covers the third compartment panel 3 and is supported by the third support beams 33 and the two fifth side panels 321, since the third compartment panel 32 is set as a U-shaped structure, the sixth side panel 322 can cover the three sides of the top panel 5 and apply lateral restraint. Thus, after the top panel 5 is connected to the third support beams 33 by part of the lateral support beams 51, this connection method can further improve the rollover impact resistance of the third compartment panel 3 and the top panel 5.

[0074] In one embodiment, the third support 34 can adopt a hollow rectangular frame structure, which can meet the requirements of lightweight design while ensuring sufficient load-bearing strength. In addition, the top surface of the third support 34 can also serve as a base for installing seats, making it easier to fix the passenger seats inside the third body component 3, thus achieving the dual functions of structural and practical purposes.

[0075] Furthermore, refer to Figures 1 to 4 As shown, in some embodiments, it further includes: a fourth compartment member 4, connected to the top surface of the third bottom plate 31, the fourth compartment member 4 supporting the top member 5 between the first compartment plate 12 and the third compartment plate 32.

[0076] Specifically, in the technical solution adopted in this application, in order to increase the length of the rectangular box, the third bottom plate 31 can be lengthened. After lengthening the third bottom plate 31, in order to maintain the structural strength of the rectangular box, a fourth box component 4 can be added to the third box component 3 to reinforce the extended part of the third bottom plate 31. The number of fourth box components 4 can be adapted according to the length of the third bottom plate 31. The fourth box components 4 are located between the first box plate 12 and the third box plate 32, and are supported on the third bottom plate 31 and the box top component 5.

[0077] Furthermore, refer to Figure 3 , Figure 4 and Figure 10 As shown, in some embodiments, the fourth compartment component 4 includes: two fourth compartment panels 41, arranged opposite to each other along the width direction of the third bottom plate 31 and connected to the top surface of the third bottom plate 31, and the two fourth compartment panels 41 are spaced apart from the two first compartment panels 12 and the third compartment panel 32, thereby forming four second doorway spaces 7 between the two first compartment panels 12 and the third compartment panel 32 on the side of the rectangular compartment through the fourth compartment panels 41, each second doorway space 7 being used to install a door; multiple fourth support beams 42, connected to the two fourth compartment panels 41 and extending along the height direction of the two fourth compartment panels 41; a fourth support body 43, connected to the top surface of the third bottom plate 31, and the two ends of the fourth support body 43 being supported on the two fourth compartment panels 41; the top component 5 is provided with multiple transverse support beams 51 arranged along the length direction, and some of the transverse support beams 51 are connected to each of the fourth support beams 42; the fourth support beams 42, the fourth support body 43 and the transverse support beams 51 together constitute the fourth reinforcing frame of the rectangular structure.

[0078] Specifically, in the technical solution adopted in this application, when the third floor plate 31 is lengthened, the distance between the first panel 12 and the third panel 32 will also increase. The two fourth panels 41 arranged opposite to each other on the third floor plate 31 can divide the space between the first panel 12 and the third panel 32 into four second doorway spaces 7 that can accommodate the car door. If there are two fourth body components 4, the four fourth panels 41 arranged in pairs can divide the space between the first panel 12 and the third panel 32 to form six second doorway spaces 7. Similarly, the number of fourth body components 4 can also be set to three, four, five, etc., which can be arranged according to the actual lengthening size of the third floor plate 31.

[0079] In some embodiments, two or more fourth support beams 42 are also provided on the fourth panel 41. The beam body of the fourth support beam 42 can be fixed to the inner wall of the corresponding fourth panel 41 by welding and is vertically arranged along the height direction of the fourth panel 41, so that it can effectively support between the third bottom plate 31 and the top member 5, and play the role of transferring and distributing load. The fourth support body 43 can be configured as a cuboid structure, which is fixed to the top surface of the third bottom plate 31 by integral molding or welding process, and the two ends of the fourth support body 43 respectively contact and support the inner walls of the two fourth panels 41, thereby forming a stable lateral support at the bottom. The straight plate structure of the top member 5 is not only used to close the top of the carriage, but also has multiple transverse support beams 51 arranged on its lower surface. Each transverse support beam 51 enhances the bending stiffness of the top member 5 itself, and some transverse support beams 51 are also connected to the top of the fourth support beam 42 to achieve skeletal integration between the third panel 3 and the top member 5 through the fourth panel member 4. In one optional connection method, some of the transverse support beams 51 and each of the fourth support beams 42 can be fixedly connected by welding or bolt fasteners. Thus, the fourth reinforcing frame, composed of the fourth support beams 42, the fourth support body 43, and some of the transverse support beams 51, forms a spatial support frame between the third floor plate 31 and the roof component 5. This further enhances the resistance of the third body component 3 and the roof component 5 to falling object impacts and rolling impacts under harsh working conditions, ensuring the integrity and safety of the overall structure, thereby significantly enhancing the overall rigidity and load-bearing capacity of the third body component 3 after the third floor plate 31 is lengthened.

[0080] In some embodiments, the fourth support beam 42 is a hollow square beam structure to further meet the lightweight requirements of the box structure. After the fourth box panel 41 is connected to the third bottom plate 31, the lengths of the two seventh side edges 411 adjacent to the third bottom plate 31 on the fourth box panel 41 are set to match the lengths of the fourth support beam 42, and the seventh side edges 411 are inwardly bent on the fourth box panel 41. This can be understood as the two seventh side edges 411 bending inward based on the fourth box panel 41. The fourth support beams 42 are arranged in pairs, for example, four fourth support beams 42, where the beam bodies of two fourth support beams 42 are connected to the seventh side edges 411 and the corresponding fourth box panels 41, thereby making the fourth support beams... The two sides of the fourth support beam 42 are in contact with the fourth side panel 41, which not only enhances the connection strength between the fourth support beam 42 and the fourth side panel 41, but also indirectly increases the thickness of the fourth support beam 42 through the seventh side 411, so as to improve the supporting force of the fourth support beam 42 on the roof member 5. In this embodiment, the number of fourth support beams 42 can be six or more, and each fourth support beam 42 is arranged along the width direction of the fourth side panel 41, wherein the two outermost fourth support beams 42 are attached to the seventh side 411 and connected to the fourth side panel 41.

[0081] In a further embodiment, the eighth side 412 of the fourth panel 41 facing away from the third bottom plate 31 can be lengthened. When the top member 5 covers the third body member 3 and is supported by the fourth support beams 42 and the four seventh side 411, the eighth side 412 can apply a lateral limit to the top member 5 along the arrangement direction of the two fourth panels 41. That is, the eighth side 412 on the two fourth panels 41 can cover both sides of the top member 5. Thus, after the top member 5 is connected to the fourth support beams 42 by a portion of the lateral support beams 51, this connection method can further improve the rollover impact resistance of the third body member 3 and the top member 5.

[0082] In one embodiment, the fourth support 43 can adopt a hollow rectangular frame structure, which can meet the requirements of lightweight design while ensuring sufficient load-bearing strength. In addition, the top surface of the fourth support 43 can also serve as a base for installing seats, making it easier to fix the passenger seats inside the third body component 3, thus achieving the dual functions of structural and practical purposes.

[0083] In some embodiments, the first support 14, the second support 24, the third support 34, and the fourth support 43, which employ a hollow rectangular frame structure, can all be constructed by enclosing multiple rectangular plates. For example, three rectangular plates can be enclosed to form a U-shaped frame structure, which is then inverted onto the corresponding base plate to form the support of the rectangular frame structure; alternatively, four rectangular plates can be used to enclose the support. Both methods in this embodiment can form a hollow structure, which is convenient for serving as a base for installing a seat.
