[0038] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0039] like Figures 1 to 5As shown, the first embodiment of the present invention provides an end wall structure, including a pair of end corner columns 100, an end top curved beam 104 and an end wall panel 108; the end corner columns 100 are slidingly connected to the side wall columns 102; the end top curved beam 104 is connected between the pair of end corner columns 100, and the end top curved beam 104 is slidingly connected to the roof curved beam 106; the end wall panel 108 is installed between the end corner columns 100 and the end top curved beam 104, and at least one of the wheel bag mounting structure and the running gear mounting structure is provided on the end wall panel 108.

[0040] According to the end wall structure provided by the embodiment of the first aspect of the present invention, the sliding connection between the end corner column 100 and the side wall column 102, as well as the sliding connection between the end top curved beam 104 and the roof curved beam 106, makes the entire end wall structure more flexible. This design allows the end wall structure to be adjusted or disassembled to a certain extent as needed during vehicle operation or maintenance, thereby improving the adaptability and convenience of the overall structure. The end wall plate 108 is directly installed between the end corner column 100 and the end top curved beam 104, and at least one of the wheel pack mounting structure and the running gear mounting structure is provided thereon. This integrated design simplifies the installation process, reduces the number of parts, and makes installation and maintenance work more convenient and efficient. At the same time, it also facilitates the rapid inspection or replacement of key components such as the wheel pack and the running gear. The tight connection between the end corner column 100, the end top curved beam 104 and the end wall plate 108 not only enhances the overall rigidity of the end wall structure, but also improves its stability under complex working conditions. This stability is crucial to ensuring the safety and reliability of vehicle operation. By providing the wheel housing and running gear mounting structures on the end wall panel 108, the end wall structure not only performs basic support and protection functions but also carries and mounts key components. This multifunctional design improves the vehicle's overall performance and operating efficiency. Innovative technologies such as sliding connections and an integrated design reduce unnecessary material and processing costs, thereby lowering the overall manufacturing cost of the end wall structure. This is of great significance for enhancing the product's market competitiveness.

[0041] Please continue to see Figures 1 to 5 The end corner post 100, a key component of the end wall structure's support frame, is connected to the side wall columns 102 using a sliding mechanism. This design allows the end corner post 100 to move horizontally within a specific range to accommodate minor deformations or adjustments during vehicle operation.

[0042] A top curved beam 104 connects between a pair of end corner posts 100, forming the top crossbeam of the end wall structure. A sliding connection is also employed between the top curved beam 104 and the roof curved beam 106, allowing for a certain degree of vertical adjustment to accommodate minor changes in the roof structure or installation requirements.

[0043] The end wall panel 108, the main component of the end wall structure, is installed between the end corner column 100 and the end top curved beam 104. The end wall panel 108 not only seals and protects the vehicle's interior but also, depending on design requirements, houses wheel housing and / or running gear mounting structures. These structures provide a stable mounting base for key components such as the wheel housing and running gear.

[0044] The tight connection between the end corner column 100, the end top curved beam 104 and the end wall panel 108, as well as the sliding connection design, make the end wall structure as a whole have high rigidity and stability, can resist external impact and vibration, and protect the safety of the vehicle's internal equipment and passengers.

[0045] The sliding connection design allows for a certain degree of adjustment of the end wall structure in both horizontal and vertical directions, thereby increasing the flexibility of the overall structure. This flexibility helps to accommodate minor deformations or adjustments during vehicle operation, ensuring smooth and reliable operation.

[0046] According to an embodiment of the present invention, the end corner column 100 includes a first bending section 110 and a first connecting section 112 . The end wall panel 108 is installed on the first bending section 110 . The first connecting section 112 is slidably connected to the side wall column 102 .

[0047] like Figure 4 As shown, according to a specific embodiment of the present invention, the design of the end corner post 100 has been further refined and optimized. In this embodiment, the end corner post 100 is divided into two main sections: a first bent section 110 and a first connecting section 112. This design not only enhances the structural strength of the end corner post 100 but also improves the flexibility and stability of its connection with the side wall column 102.

[0048] The first bent section 110 is the portion of the end corner post 100 used to mount the end wall panel 108. It typically features a curved or angled design to accommodate the installation requirements of the end wall panel 108 and the interior space layout of the vehicle. This design not only ensures a secure fit of the end wall panel 108 on the end corner post 100 but also enhances the overall visual appearance of the end wall structure.

[0049] The first connecting section 112 is the portion of the end corner post 100 that is used for sliding connection with the side wall column 102. It typically features a sliding groove or rail structure that matches the side wall column 102, enabling a sliding connection between the two. This sliding connection allows for fine-tuning of the end corner post 100 horizontally relative to the side wall column 102 to accommodate minor deformation or adjustments during vehicle operation. Furthermore, the sliding connection provides a certain cushioning effect, reducing the impact of vehicle vibration and impact on the end wall structure.

[0050] The division of labor and cooperation between the first bending section 110 and the first connecting section 112 makes the end corner column 100 more structurally reasonable and stable. This design not only improves the bearing capacity of the end corner column 100 itself, but also enhances the structural strength of the entire end wall structure. The sliding connection between the first connecting section 112 and the side wall column 102 enables the end corner column 100 to have a certain adjustment capability in the horizontal direction. This flexibility helps to adapt to minor deformations or adjustment requirements during vehicle operation, ensuring the stability and reliability of vehicle operation. The design of the first bending section 110 makes the installation of the end wall panel 108 more convenient and stable. At the same time, the sliding connection design also simplifies the connection process between the end corner column 100 and the side wall column 102, reducing the difficulty of installation and maintenance.

[0051] According to an embodiment of the present invention, the end roof bow beam 104 includes a second bending section 114 and a second connecting section 116 . The end wall panel 108 is mounted on the second bending section 114 . The second connecting section 116 is slidably connected to the roof bow beam 106 .

[0052] like Figure 5 As shown, according to a specific embodiment of the present invention, the design of the end top bow beam 104 has been further refined and optimized. In this embodiment, the end top bow beam 104 is divided into a second bending section 114 and a second connecting section 116. This design is intended to improve the stability and flexibility of the connection between the end top bow beam 104, the end wall panel 108, and the roof bow beam 106.

[0053] The second curved section 114 is the portion of the end top curved beam 104 used to mount the end wall panel 108. Similar to the first curved section 110 of the end corner post 100, the second curved section 114 also features a curved or angled design to accommodate the installation requirements of the end wall panel 108 and the interior space layout of the vehicle. This design ensures that the end wall panel 108 is securely mounted on the end top curved beam 104 while enhancing the integrity and aesthetics of the entire end wall structure.

[0054] The second connecting section 116 is the portion of the end top bow 104 that is used for sliding connection with the roof bow 106. It typically features a matching sliding groove or rail structure with the roof bow 106 to achieve a sliding connection between the two. This sliding connection allows for a certain degree of vertical or horizontal fine-tuning of the end top bow 104 on the roof bow 106 (depending on the design of the sliding groove or rail), to accommodate minor changes in the roof structure or installation requirements. The sliding connection also provides a buffering effect, reducing the impact of vibration and impact on the end wall structure during vehicle operation.

[0055] The cooperation between the second bending section 114 and the second connecting section 116 makes the end top curved beam 104 more structurally stable. This design not only improves the load-bearing capacity of the end top curved beam 104 itself, but also enhances the stability of the entire end wall structure. The sliding connection between the second connecting section 116 and the roof curved beam 106 allows the end top curved beam 104 to have a certain degree of adjustment capability in the vertical or horizontal direction (depending on the specific design). This flexibility helps to adapt to various situations that may arise during vehicle operation, ensuring the smooth and reliable operation of the vehicle. The design of the second bending section 114 makes the installation of the end wall panel 108 more convenient and stable. At the same time, the sliding connection design also simplifies the connection process between the end top curved beam 104 and the roof curved beam 106, reducing the difficulty of installation and maintenance. By optimizing the design of the end top curved beam 104, vibration and noise during vehicle operation can be further reduced, improving passenger comfort and satisfaction. At the same time, the stable end wall structure also helps to improve the overall performance and safety of the vehicle.

[0056] According to one embodiment of the present invention, the running gear mounting structure includes an mounting top plate 118, a mounting side plate 120 and an mounting end plate 122; the mounting top plate 118 is connected to the end wall plate 108; the mounting side plate 120 is connected between the mounting top plate 118 and the end wall plate 108; the mounting end plate 122 is connected to the ends of the mounting top plate 118 and the mounting side plate 120 and is connected to the passenger compartment floor.

[0057] like Figures 1 to 3 As shown, according to one embodiment of the present invention, the running gear mounting structure is mainly composed of a mounting top plate 118, a mounting side plate 120 and a mounting end plate 122. These components work together to provide stable and reliable support for the installation of the running gear.

[0058] The top mounting plate 118 is a key component of the running gear mounting structure and is directly connected to the end wall 108. The design of the top mounting plate 118 must consider its load-bearing capacity, rigidity, and connection to the end wall 108 to ensure it can firmly support the weight of the running gear and transmit the associated forces and moments.

[0059] The mounting side panels 120 are connected between the mounting top panel 118 and the end wall panels 108, forming the lateral boundaries of the running gear mounting structure. The design of the mounting side panels 120 requires careful consideration of their tight connection with the mounting top panel 118 and the end wall panels 108, as well as their own strength and rigidity requirements. They must not only withstand lateral forces from the running gear but also maintain the overall stability of the structure.

[0060] The mounting end plate 122 is located at the ends of the top mounting plate 118 and the side mounting plates 120 and is connected to the passenger compartment floor. The design of the mounting end plate 122 ensures a secure and reliable connection with the top mounting plate 118, the side mounting plates 120, and the passenger compartment floor. It not only seals the running gear installation area but also, through its connection to the passenger compartment floor, further enhances the stability of the entire running gear installation structure.

[0061] Through the coordinated action of the mounting top plate 118, the mounting side plates 120 and the mounting end plates 122, a stable mounting platform is provided for the running gear. This design ensures the stability and reliability of the running gear during vehicle operation and reduces the risk of failure due to vibration or impact. The reasonable connection and structural design between the various components give the running gear mounting structure a high load-bearing capacity. It can withstand various forces and moments from the running gear, ensuring the smoothness and safety of vehicle operation. The design of the running gear mounting structure fully considers the utilization of the vehicle's interior space. Through reasonable layout and compact structural design, space occupancy is minimized, providing more available space for other equipment and passengers inside the vehicle. The connection method between the various components is simple and clear, which facilitates installation and maintenance work. When the running gear needs to be inspected or replaced, the relevant components can be easily disassembled and installed, which improves work efficiency.

[0062] According to an embodiment of the present invention, a vertical shock absorber mounting seat 124 is provided on the mounting side plate 120 , and an empty spring mounting seat 126 and a height valve mounting seat 128 are provided on the mounting top plate 118 .

[0063] See also Figure 3 In a specific embodiment of the present invention, the detailed design of the running gear mounting structure is further optimized. This embodiment focuses on improving the smoothness and comfort of vehicle operation by providing specific mounting seats on the mounting side panels 120 and the mounting top panel 118.

[0064] The mounting side plate 120 is provided with a vertical damper mounting base 124, specifically designed for mounting a vertical damper. Vertical dampers play a key role in vehicle operation, absorbing and damping vertical vibrations, thereby improving passenger comfort and reducing fatigue damage to the vehicle structure. By placing the vertical damper mounting base 124 on the mounting side plate 120, the damper is securely mounted on the running gear mounting structure and effectively performs its vibration damping function.

[0065] The top mounting plate 118 is equipped with an air spring mount 126 and a height valve mount 128. The air spring mount 126 is designed to ensure the air spring is securely mounted on the running gear mounting structure and works in conjunction with other suspension system components (such as the shock absorbers) to achieve optimal suspension performance. Installing a height valve on the height valve mount 128 enables precise control of the vehicle's suspension height, ensuring optimal vehicle performance under various operating conditions.

[0066] The synergistic effect of the vertical shock absorber and air spring significantly reduces vibration and impact during vehicle operation, enhancing passenger comfort. The automatic adjustment function of the height valve ensures a stable suspension height under various operating conditions, thereby improving driving stability and safety. The design of the various mounting brackets ensures that each suspension system component is securely mounted on the running gear mounting structure and fully utilizes its performance, achieving optimal suspension performance. The simple and clear design of each mounting bracket facilitates installation and maintenance. When it is necessary to inspect or replace suspension system components, the relevant components can be easily removed and installed.

[0067] According to an embodiment of the present invention, a reinforcement plate 130 is provided between the mounting side plate 120 and the end wall plate 108 , and the vertical vibration damper mounting seat 124 is provided between the reinforcement plate 130 and the mounting side plate 120 .

[0068] See also Figure 3 First, the side panels 120 and the end wall panels 108 are installed as the main load-bearing and supporting components of the mechanical equipment or structure, and a stable connection needs to be established between them. This connection must not only be able to withstand normal working loads, but also have a certain ability to resist deformation and damage.

[0069] In order to further enhance the strength of the connection between the mounting side panel 120 and the end wall panel 108, a reinforcing plate 130 is cleverly provided between the two. This reinforcing plate 130 is fixed to the mounting side panel 120 and the end wall panel 108 by welding, bolting or other reliable connection methods, forming a more solid structural whole.

[0070] The vertical vibration damper mounting base 124 is disposed between the reinforcing plate 130 and the mounting side plate 120. This arrangement not only ensures the stability of the vibration damper installation, but also enables the vibration damper to more effectively absorb and disperse vertical vibrations, thereby protecting other components of the equipment or structure from vibration damage.

[0071] The introduction of reinforcement plate 130 significantly enhances the structural strength of the connection between mounting side panel 120 and end wall panel 108, improving the overall structural stability and load-bearing capacity. This allows the equipment or structure to maintain its form and functional integrity even when subjected to high operating loads. Placing vertical vibration damper mounting base 124 between reinforcement plate 130 and mounting side panel 120 simplifies the installation process and makes subsequent maintenance and replacement easier. This reduces equipment maintenance costs and improves equipment availability.

[0072] According to an embodiment of the present invention, a rivet hole 132 is defined on the mounting end plate 122 .

[0073] See also Figure 2 In one embodiment of the present invention, rivet holes 132 are provided on the mounting end plate 122 to achieve a more stable and efficient connection. This design detail not only enhances the strength and rigidity of the mounting end plate 122, but also simplifies the installation process and improves the reliability of the overall structure.

[0074] Specifically, mounting end plate 122, a key component in a mechanical device or structure, is typically used to connect to other components or structures. To ensure the stability and durability of the connection, a mechanical connection method called riveting is employed. Riveting uses rivets to tightly secure two or more components together, forming an inseparable connection.

[0075] In order to achieve riveting, a plurality of rivet holes 132 are pre-designed and opened on the mounting end plate 122. By providing the rivet holes 132, it is convenient to carry out riveting connection with the chassis.

[0076] By providing rivet holes 132 in the mounting end plate 122 and employing riveting for connection, the strength and rigidity of the joint are significantly enhanced. This connection method can withstand greater loads and vibration shocks, improving the stability and safety of the overall structure. The design of the rivet holes 132 makes installation much simpler and faster; simply insert the rivet into the corresponding rivet hole 132 and secure it with a riveting tool to complete the connection. This not only improves installation efficiency but also reduces installation costs.

[0077] According to one embodiment of the present invention, the wheel bag mounting structure and the end wall plate 108; and / or the running gear mounting structure and the end wall plate 108 are spot-welded.

[0078] In one embodiment of the present invention, spot welding, a highly efficient welding method, is employed to achieve a secure connection between the wheel assembly mounting structure and the running gear mounting structure. Spot welding involves instantaneously heating and pressurizing two or more metal parts at predetermined locations using welding equipment, causing them to partially melt and bond together.

[0079] Specifically, the wheel housing mounting structure, a key component supporting and securing the wheels, must be securely attached to the end wall 108 to ensure wheel stability and safety. Similarly, the running gear mounting structure is a crucial component of the vehicle's running system, and its connection to the end wall 108 must also be reliable. Therefore, spot welding is used to connect these two structures to the end wall 108.

[0080] Spot welding effectively and firmly connects the wheel housing mounting structure, the running gear mounting structure, and the end wall plate 108, enhancing the strength and rigidity of the entire structure. This helps improve the vehicle's load-bearing capacity and vibration resistance, ensuring stable operation under various operating conditions.

[0081] Improved connection accuracy: Spot welding connections are characterized by high precision, ensuring accurate and consistent weld point placement. This helps ensure assembly accuracy and fit between components, reducing performance degradation or failures caused by connection errors. The spot welding process is simple and fast, significantly improving production efficiency. Furthermore, due to the high degree of automation of spot welding equipment, it can achieve high-volume, high-efficiency production, meeting the demands of modern production.

[0082] A second embodiment of the present invention provides a vehicle body, comprising the above-mentioned end wall structure.

[0083] According to the car body provided by the embodiment of the second aspect of the utility model, since the end wall structure itself has high rigidity and stability, its application in the car body design can significantly improve the overall structural strength of the car body. This helps to resist external shocks and vibrations and protect the safety of equipment and passengers in the car. The design of the end wall structure takes into account the installation requirements of the wheel bag and the running gear, and optimizes the space utilization in the car body through reasonable layout. This not only provides sufficient installation space for key components, but also ensures the smooth operation and efficient utilization of other areas in the car body. The connection method between the end wall structure and the car body is flexible and diverse, and can be adjusted according to different vehicle models and usage requirements. This adaptability enables the car body to be widely used in various rail transit vehicles to meet different operating conditions and customer needs.

[0084] A third embodiment of the present invention provides a rail vehicle, comprising the above-mentioned end wall structure; or, the above-mentioned vehicle body.

[0085] The vehicle provided by the embodiment of the third aspect of the present invention, whether directly employing an end wall structure or incorporating a vehicle body comprising the end wall structure, significantly enhances the overall structural strength and stability of the rail vehicle. This enhancement helps to resist external shocks, vibrations, and adverse weather conditions, protecting the vehicle's internal equipment and the safety of passengers. The design of the end wall structure and vehicle body takes passenger comfort into consideration, providing a more pleasant riding experience for passengers by reducing noise and vibration and improving the air quality inside the vehicle.
