Detailed Embodiment

[0030] The following will further describe in detail the embodiments of the present utility model in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0031] As Figures 1 to 4 shown, the first aspect embodiment of the present utility model provides an end beam, including:

[0032] The end beam body 100 has an installation cavity 102 formed therein.

[0033] The mounting seat 104 is embedded in the installation cavity 102 through the first fastener 106, and the mounting seat 104 is provided with mounting holes 107 for mounting the intermediate coupler.

[0034] The access hole is opened in the end beam body 100 and communicates with the installation cavity 102, and the mounting seat 104 is adapted to enter the installation cavity 102 through the access hole.

[0035] According to the end beam provided by the first aspect embodiment of the present invention, by providing the access hole, the mounting seat 104 can conveniently enter the installation cavity 102 through this hole for fixation, greatly improving the installation efficiency and reducing the installation difficulty. The mounting seat 104 is embedded in the installation cavity 102 through the first fastener 106. This fixing method makes the connection between the mounting seat 104 and the end beam body 100 firm, capable of withstanding large tensile forces and impact forces, ensuring the stability and safety of the connection of the intermediate coupler. When it is necessary to replace or repair the mounting seat 104, the mounting seat 104 can be easily placed into the installation cavity 102 through the access hole, facilitating disassembly and installation operations, and reducing the maintenance cost and time. The end beam is flexibly designed, and the positions and sizes of the mounting seat 104 and the access hole can be adjusted according to specific requirements, suitable for the installation requirements of different models and specifications of intermediate couplers, having good versatility and scalability. In summary, the end beam of the present invention fully considers factors such as installation convenience, structural stability, and easy maintainability in its structural design, and has high practical value and broad application prospects.

[0036] Please continue to refer to Figures 1 to 4 , the first aspect embodiment of the present invention aims to provide an end beam with a reasonable structural design, convenient and stable installation, and is particularly suitable for suspended monorail vehicles. The end beam mainly consists of an end beam body 100, a mounting seat 104, and an access hole.

[0037] The end beam body 100 serves as the main body of the entire end beam. The end beam body 100 is made of high-strength materials, such as an aluminum alloy structure, to ensure its load-bearing capacity and structural strength. Inside the end beam body 100, a specific space is designed as the installation cavity 102 for accommodating and fixing other components.

[0038] The mounting seat 104 is embedded and fixed in the installation cavity 102 through the first fastener 106 (such as bolts, rivets, or welding, etc.). The mounting seat 104 is provided with precise mounting holes 107, and these mounting holes 107 are used for mounting the intermediate coupler. The design of the mounting seat 104 needs to consider the compatibility with the intermediate coupler and the convenience of installation.

[0039] For the convenience of installing the mounting base 104 and its later maintenance, an access hole is specially opened on the end beam body 100, and this access hole is communicated with the installation cavity 102. The mounting base 104 can be easily placed into the installation cavity 102 through this access hole and fixed by the first fastener 106. The design of the access hole needs to consider its size and position to ensure the smoothness and safety of the installation process.

[0040] According to an embodiment of the present invention, it further includes a sealing plate 108, and the sealing plate 108 is installed on the access hole through the second fastener 110.

[0041] As Figure 1 shown, in a specific embodiment of the present invention, in order to enhance the overall structural strength and sealing performance of the end beam, a component of the sealing plate 108 is further added. The main function of the sealing plate 108 is to close the access hole to prevent dust, moisture or other impurities from entering the installation cavity 102 and causing damage to the mounting base 104 or affecting its function.

[0042] Specifically, the sealing plate 108 is designed to have a shape and size matching the access hole to ensure that it can closely fit on the end beam body 100. The sealing plate 108 is installed at the access hole through the second fastener 110 (such as bolts, nuts, rivets, etc.). During the installation process, first, the sealing plate 108 needs to be aligned with the access hole, and then it is fixed on the end beam body 100 through the second fastener 110 to form a tight sealing structure.

[0043] The sealing plate 108 effectively closes the access hole, preventing the intrusion of the external environment, such as dust and moisture, thereby protecting the components in the installation cavity 102 and extending the service life of the equipment. The tight connection between the sealing plate 108 and the end beam body 100 not only enhances the sealing performance but also improves the overall structural strength of the end beam to a certain extent, making it more capable of withstanding various external forces and impacts. The design of the sealing plate 108 makes the appearance of the end beam more neat and beautiful, avoiding the visual disharmony that may be caused by the exposure of the access hole. Although the sealing plate 108 increases the sealing performance, when it is necessary to enter the installation cavity 102 for maintenance or component replacement, the sealing plate 108 can still be easily removed by disassembling the second fastener 110, and the operation is simple and fast.

[0044] According to an embodiment of the present invention, an installation groove 112 is provided at the position corresponding to the access hole on the end beam body 100, and the sealing plate 108 is installed in the installation groove 112.

[0045] See Figure 4, in a specific embodiment of the present utility model, in order to further optimize the connection method and installation efficiency between the sealing plate 108 and the end beam body 100, an installation groove 112 is specially designed at the position on the end beam body 100 corresponding to the access hole. The size and shape of this installation groove 112 are matched with the sealing plate 108, aiming to provide an accurate positioning and installation interface.

[0046] Specifically, the installation groove 112 is designed on the outer surface of the end beam body 100, corresponding to the position of the access hole. When the sealing plate 108 is ready to be installed, it can be accurately placed into the installation groove 112 to ensure a tight fit between the sealing plate 108 and the end beam body 100. Subsequently, the sealing plate 108 is fixed in the installation groove 112 through the second fastener 110 (such as bolts, nuts, etc.) to complete the installation process.

[0047] The installation groove 112 provides a clear installation position and direction for the sealing plate 108, making the installation process faster and more accurate, and reducing problems such as poor sealing or unstable structure caused by improper installation. The tight fit between the sealing plate 108 and the installation groove 112, as well as the fixation through the second fastener 110, makes the connection between the sealing plate 108 and the end beam body 100 more firm, improving the stability and reliability of the overall structure. The design of the installation groove 112 makes the sealing plate 108 flatter and more beautiful after installation, integrating with the outer surface of the end beam body 100 and enhancing the overall visual effect of the equipment. The introduction of the installation groove 112 simplifies the installation steps of the sealing plate 108, enabling the operator to complete the installation work more conveniently and improving the work efficiency.

[0048] According to an embodiment of the present utility model, it further includes an installation member 114. The installation member 114 is embedded in the installation cavity 102 through a third fastener 116, and the second fastener 110 is installed on the installation member 114.

[0049] See Figure 4 , in an embodiment of the present utility model, in order to further enhance the connection stability and flexibility between the sealing plate 108 and the end beam body 100, a new component, the installation member 114, is also introduced. The installation member 114 is designed to have appropriate strength and shape so as to be embedded in the installation cavity 102 through a third fastener 116 (such as bolts, rivets or welding, etc.). And the previously mentioned second fastener 110 is installed on the installation member 114 to fix the sealing plate 108.

[0050] Specifically, the mounting member 114 is precisely placed at a predetermined position within the mounting cavity 102 and forms a firm connection with the end beam body 100 through the third fastener 116. The design of the mounting member 114 takes into account its load-bearing capacity, compatibility with the sealing plate 108, and ease of installation. When installing the sealing plate 108, first, the sealing plate 108 is fixed to the mounting member 114 through the second fastener 110 (such as a combination of bolts and nuts), thus completing the installation of the sealing plate 108.

[0051] By introducing the mounting member 114 as the connection structure between the sealing plate 108 and the end beam body 100, the stability and reliability of the connection are enhanced. The mounting member 114 disperses the force on the sealing plate 108, preventing stress concentration problems caused by directly fixing it to the end beam body 100. The design of the mounting member 114 allows for fine-tuning of the installation position of the sealing plate 108 to adapt to different installation requirements and environmental conditions. This flexibility improves the versatility and adaptability of the end beam. The presence of the mounting member 114 makes the installation and disassembly of the sealing plate 108 easier. When maintenance or replacement of the sealing plate 108 is required, the sealing plate 108 can be easily removed by loosening the second fastener 110 without disassembling the entire end beam. The mounting member 114 is embedded in the mounting cavity 102 through the third fastener 116 to form an integral structure with the end beam body 100, enhancing the overall structural strength of the end beam. This structural reinforcement enables the end beam to better withstand external impacts and loads.

[0052] According to an embodiment of the present invention, the mounting member 114 includes a first mounting portion 118 and a second mounting portion 120 that are connected to each other. The first mounting portion 118 is provided with a first connection hole, and the second mounting portion 120 is provided with a second connection hole. The third fastener 116 is connected to the first connection hole, and the second fastener 110 is connected to the second connection hole.

[0053] See Figure 4 , in an embodiment of the present invention, the mounting member 114 is designed as a two-part structure, namely the first mounting portion 118 and the second mounting portion 120, and these two parts are connected to each other to form an integral whole. This design not only enhances the strength and stability of the mounting member 114 but also improves its flexibility and adaptability during the installation process.

[0054] The first mounting portion 118 is the main load-bearing part of the mounting member 114. It is designed to match the mounting cavity 102 of the end beam body 100 and forms a firm connection with the end beam body 100 through the third fastener 116 (such as bolts, rivets, etc.). A first connection hole is provided on the first mounting portion 118, and the first connection hole is used to install the third fastener 116 to achieve the fixed connection of the mounting member 114 itself with the end beam body 100.

[0055] The second installation part 120 serves as the installation foundation of the sealing plate 108, and second connection holes are provided on the second installation part 120. The second connection holes cooperate with the second fasteners 110 (such as a combination of bolts and nuts) to fixedly install the sealing plate 108, thereby realizing the indirect connection between the sealing plate 108 and the end beam body 100.

[0056] By dividing the installation part 114 into the first installation part 118 and the second installation part 120 and fixing them respectively through the third fasteners 116 and the second fasteners 110, the whole connection structure becomes more stable and reliable. This split design helps to disperse the force, reduce stress concentration, and improve the connection strength. When it is necessary to maintain or replace the sealing plate 108, only the second fasteners 110 need to be loosened to easily remove the sealing plate 108, without disassembling the whole installation part 114 or the end beam body 100. This design facilitates the later maintenance and servicing work.

[0057] According to an embodiment of the present invention, there are at least two installation cavities 102, and the at least two installation cavities 102 are arranged along the height of the end beam body 100.

[0058] See Figure 4 In an embodiment of the present invention, the design of the end beam body 100 is further optimized, specifically reflected in the layout of the installation cavities 102. In this embodiment, the number of installation cavities 102 is set to be at least two, and these installation cavities 102 are arranged along the height direction of the end beam body 100. This design makes the end beam body 100 more compact in structure, and at the same time improves the diversity and flexibility of its functions.

[0059] Specifically, each installation cavity 102 can independently carry and fix different components or assemblies. By arranging these installation cavities 102 along the height direction, the space resources of the end beam body 100 can be fully utilized, waste can be avoided, and the overall structure becomes more reasonable and compact.

[0060] In addition, the installation cavities 102 arranged along the height direction are also convenient for maintenance and repair work. When it is necessary to enter a specific installation cavity 102 for operation, it can be easily entered through the corresponding access holes (as described above), without disassembling or moving the whole end beam. This design greatly improves the maintenance efficiency and convenience.

[0061] By arranging a plurality of mounting cavities 102 in the height direction, the space of the end beam body 100 is more fully utilized. This helps to reduce material waste, lower costs, and improve the overall performance of the equipment. The mounting cavities 102 arranged in the height direction facilitate maintenance and repair work. When a component fails or needs to be replaced, it can be quickly located and repaired, thereby reducing downtime and maintenance costs. The compact arrangement of the plurality of mounting cavities 102 makes the overall structure of the end beam body 100 more compact and stable. This helps to improve its load-bearing capacity and impact resistance, and ensures the stable operation of the equipment in harsh environments.

[0062] According to an embodiment of the present invention, along the length direction of the end beam body 100, the mounting seat 104 is arranged in the middle of the end beam body 100.

[0063] See Figure 1 , in an embodiment of the present invention, the structural layout of the end beam body 100 is further optimized, especially in the position setting of the mounting seat 104. In this embodiment, the mounting seat 104 is clearly arranged at the middle position of the end beam body 100 along the length direction. This layout design aims to improve the overall stability and balance of the end beam, while optimizing its load-bearing capacity and functional layout.

[0064] Specifically, the mounting seat 104, as a key component for connecting and fixing the middle coupler, the selection of its position has an important impact on the performance of the end beam. Arranging the mounting seat 104 in the middle of the end beam body 100 can ensure that when bearing loads, the force line distribution is more uniform, reducing the stress concentration problem caused by eccentric loading. This not only improves the load-bearing capacity and stability of the end beam, but also extends its service life.

[0065] In addition, placing the mounting seat 104 in the middle also helps to optimize the functional layout of the end beam. Since the middle position is usually more spacious and convenient for operation, more key components or auxiliary equipment can be arranged around the mounting seat 104, thereby achieving the concentration and efficient utilization of functions. At the same time, this layout also provides convenient conditions for subsequent maintenance and repair work.

[0066] Setting the mounting base 104 in the middle of the end beam body 100 can significantly improve the stability and balance of the end beam during loading. This helps reduce vibration and noise problems caused by eccentric loading and improves the running smoothness of the equipment. As one of the support points of the end beam body 100, setting the mounting base 104 here can fully exert its load-bearing potential. This layout makes the end beam more stable and reliable when bearing external loads, improving the overall load-bearing capacity. Placing the mounting base 104 in the middle also helps optimize the functional layout of the end beam. By concentrating key components and auxiliary equipment around the mounting base 104, the concentration and efficient utilization of functions can be achieved, improving the overall performance and efficiency of the equipment.

[0067] In the second aspect of the embodiments of the present utility model, a vehicle body is provided, including a roof longitudinal beam and the end beam of the above-described embodiment, and the end beam is connected to the roof longitudinal beam.

[0068] According to the vehicle body provided by the second aspect of the embodiments of the present utility model, through the close combination of the roof longitudinal beam and the end beam, an important support framework of the vehicle body is formed, significantly enhancing the overall stability and anti-roll ability of the vehicle body. At the same time, it is also beneficial to realize the installation of the middle coupler, saving the installation space of the middle coupler and improving the adaptability of the installation of the middle coupler of the middle vehicle.

[0069] Specifically, the second aspect of the embodiments of the present utility model proposes a vehicle body, which includes a roof longitudinal beam and the above-described end beam embodiment. This combination not only inherits the advantages of the end beam design but also further improves the overall performance and stability of the vehicle body through the synergistic effect of the roof longitudinal beam and the end beam.

[0070] As one of the main load-bearing and supporting structures of the vehicle body, the roof longitudinal beam extends along the length direction of the vehicle body and plays an important role in transmitting and dispersing the loads of the roof and the upper structure. The roof longitudinal beam is usually made of high-strength materials to ensure its sufficient rigidity and load-bearing capacity.

[0071] The end beam is connected to the end of the roof longitudinal beam. To ensure the stability and reliability of the connection, various connection methods can be used, such as welding, bolt connection, or riveting.

[0072] In the third aspect of the embodiments of the present utility model, a vehicle is provided, including the end beam of the above-described embodiment, or the vehicle body of the above-described embodiment.

[0073] According to the vehicle provided by the third aspect embodiment of the present utility model, the structural reliability of the vehicle is enhanced through the optimized design of the end beam and the vehicle body. Through reasonable layout and connection methods, the close cooperation and coordinated operation among various components of the vehicle are ensured. This structural reliability will enable the vehicle to maintain a stable operating state under various complex working conditions and reduce the possibility of failures. The optimized design of the end beam and the vehicle body also takes into account the convenience of maintenance. They adopt a structural layout and connection methods that are easy to maintain and repair, enabling maintenance personnel to more conveniently access and operate relevant components during daily maintenance and repair. This will greatly reduce the maintenance cost and downtime of the vehicle and improve the usage efficiency and economic benefits of the vehicle.

[0074] Specifically, the third aspect embodiment of the present utility model proposes a vehicle that particularly integrates the end beam or the vehicle body in the above-mentioned embodiments as one of its core structures. This design not only reflects the optimization and innovation of the key components of the vehicle but also enhances the overall performance and reliability of the vehicle through the unique advantages of the end beam or the vehicle body.

[0075] The vehicle in this embodiment can directly adopt the end beam in the above-mentioned embodiments. The end beam is carefully designed and optimized, having the installation convenience of the middle coupler as well as excellent load-bearing capacity, stability, and connection performance. The vehicle can also entirely adopt the vehicle body in the above-mentioned embodiments. This vehicle body not only includes the optimized end beam but also integrates other key components such as the roof longitudinal beam, forming a complete and coordinated structural system. The design of the vehicle body fully considers the usage requirements and environmental conditions of the vehicle to ensure its excellent performance and reliability under various working conditions.

[0076] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit them; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present utility model.
