[0028] As an important rail transit tool, the 160-km / h power-concentrated multiple unit has a crucial position in the design and optimization of its internal facilities.

[0029] Currently, the 160-km / h power-concentrated multiple unit adopts the original in-service vehicle installation structure for the installation of the light strip and the side wall decorative panel. This structure is mainly based on traditional installation concepts and processes, and to a certain extent, it ensures the basic installation requirements.

[0030] However, there are many unreasonable aspects in the existing installation structure. During the actual disassembly and assembly process, the procedures are cumbersome and complex, consuming a large amount of manpower and time, and it is difficult to achieve the requirements of simple, labor-saving, and high-efficiency installation. At the same time, there are also deficiencies in terms of lightweight and modularization, which cannot meet the pursuit of improving the vehicle performance of modern multiple units, affecting both the passenger comfort and further improvement of the vehicle's service performance.

[0031] Appendix Figure 1 is a schematic diagram of the installation structure of the light strip profile provided by the embodiment of the present application; Appendix Figure 2 is a schematic diagram of the structure of the profile board provided by the embodiment of the present application.

[0032] Referring to Appendix Figure 1 and Figure 2 shown, the present application provides a plate body, including an inner wall 100 and a top plate 200. The top plate 200 is arranged on the side of the inner wall 100. A plurality of hole bodies are formed on the inner wall 100, and a profile board 300 is installed at the hole bodies. The profile board 300 includes an arc-shaped board 310 and at least two fixing boards 320. One of the fixing boards 320 is connected to the arc-shaped board 310. The arc-shaped board 310 extends towards the top plate 200 and abuts against the top plate 200. On one side of the other fixing board 320, a decorative board 400 is cooperatively installed, and the decorative board 400 is connected to the inner wall 100, so as to simplify the installation process of the profile board 300 and improve the installation work efficiency.

[0033] It should be noted that the light strip profile provided in the embodiments of the present application is applicable to the 160-kilometer power-concentrated multiple unit train, and the light strip profile provided in the present application can also be applied to other environments, which is not specifically limited herein. The profile plate 300 used in the present application is processed from aluminum profile. In the present application, the profile plate 300 needs to undergo casting, extrusion, stretching, and aging treatments. In the casting stage, the profile plate 300 needs to be heated to a high temperature and filled with argon for degassing operation to reduce the pores of the profile plate 300. In the extrusion forming stage, the aluminum rod is extruded from the die hole to form the profile plate 300 with the same shape as the die interface. Finally, the profile plate 300 is processed through surface treatment and put into actual production and use.

[0034] It should be noted that the profile plate 300 provided in the embodiments of the present application mainly consists of three parts, namely, the arc plate 310, the fixing plate 320, and the mounting plate 330. The original profile plate 300 not only needs to be provided with a light strip mounting bracket, but also needs to be provided with a slit-blocking profile and a plate body at the upper and lower ends of the light strip mounting bracket respectively, and the slit-blocking profile, the plate body, and the light strip mounting bracket all need to be connected to the inner wall of the vehicle and the decorative plate through fasteners, which has relatively high precision requirements and is not convenient for actual installation. The profile plate 300 provided in the present application is an integrally formed structure, including two fixing plates 320. One of the fixing plates 320 is used for being fitted and connected to the inner wall 100, and is fixedly connected by using an M8 bolt; the other fixing plate 320 is used for being connected to the decorative plate 400, and is fixedly connected by using an M5 bolt. An arc plate 310 is connected to the upper end of the fixing plate 320 close to the inner wall 100, and the end of the arc plate 310 abuts against the top plate 200. Compared with the original profile plate 300, the profile plate 300 of the present application has fewer parts that need to be accurately positioned, and this structure eliminates the mounting bracket and the plate body structure in the original structure, enabling the vehicle body system to cancel the workload of welding the mounting seat. The connection part between the inner wall 100 and the profile plate 300 avoids the adjustment of flatness and perpendicularity, simplifies the process, improves the installation efficiency, and the integrally formed structure can provide greater structural strength.

[0035] According to an implementation manner provided by the embodiments of the present application, holes are formed in both of the two fixing plates 320. One of the fixing plates 320 is fitted to the inner wall 100, and two through holes are formed in this fixing plate 320 corresponding to the holes formed in the inner wall 100.

[0036] It should be noted that the lengths of the two fixing plates 320 provided in the embodiments of the present application are different. The length of the longer-end fixing plate 320 is 159 mm, and the length of the shorter fixing plate 320 is 97 mm. The two fixing plates 320 are fixedly connected to each other. The shorter fixing plate 320 is arranged at a position 28 mm away from the lower end of the longer fixing plate 320. The thickness of both fixing plates 320 is set to 4 mm. Based on the shorter fixing plate 320, the two holes on the longer fixing plate 320 are respectively arranged on both sides of the shorter fixing plate 320, so that the longer fixing plate 320 can be firmly attached to the surface of the inner wall 100, thereby improving the overall connection strength of the profile plate 300.

[0037] It should also be noted that in the complex operating environment of the bullet train, one fixing plate 320 is attached to the inner wall 100, and the two through holes formed thereon correspond to the holes on the inner wall 100. This design provides precise positioning for the connection between the equipment and the inner wall of the bullet train. By passing through the corresponding holes with connecting pieces such as bolts and rivets, the fixing plate 320 can be firmly fixed on the inner wall 100, ensuring that the entire structure remains stable under the continuous vibration and various stresses generated during the high-speed running of the bullet train and will not loosen or displace. At the same time, this hole corresponding design greatly improves the installation efficiency. When assembling the bullet train or maintaining and replacing the equipment, the staff can quickly align the holes for installation operations, reducing the installation time and labor costs. Moreover, the existence of the holes can also reduce the weight of the fixing plate 320 itself, which conforms to the lightweight design concept of the bullet train and reduces energy consumption while ensuring the structural strength. In addition, due to the special setting of the angle between the fixing plates 320 and the cooperation of the hole connection, the entire structure can evenly disperse the force to the inner wall of the bullet train through the interaction between the connecting pieces and the holes under the action of forces in different directions, further improving the reliability and safety of the overall structure and providing a solid guarantee for the stable operation of the bullet train.

[0038] According to an implementation manner provided by the embodiments of the present application, the two fixing plates 320 intersect, and the angle between one fixing plate 320 and the other fixing plate 320 is θ, satisfying 85° < θ < 89°.

[0039] It should be noted that in the profile plate 300 provided by the present application, the angle between the two fixing plates 320 is 86°. The inclined setting of the fixing plate 320 is on the one hand to fit the inner wall 100 of the adapted bullet train, and on the other hand, the inclined fixing plate 320 and the mounting plate 330 form an acute triangle structure, which improves the structural strength of the entire profile plate 300.

[0040] Moreover, such an included angle design enables the fixed plate 320 to better disperse these forces and convert complex external forces into a more reasonable internal stress distribution. For example, when the bullet train takes a curve, due to the inclination and lateral force generated by the vehicle body, this included angle allows the fixed plates 320 to work together to effectively offset part of the lateral force and avoid damage to the arc plate 310 and related components caused by uneven stress. At the same time, within this included angle range, the overall structural stability can also be enhanced. When the bullet train encounters sudden track irregularities, the special structure formed by the intersection of the two fixed plates 320 can, like an intelligent buffer system, automatically adjust the way of bearing and dispersing the impact force to ensure that the rubber strip 321 can always closely fit the top plate 200 and continuously play its roles of buffering, sealing, and noise reduction. Moreover, this included angle design can also optimize the internal space layout of the bullet train to a certain extent, providing more favorable conditions for the installation of internal equipment and the planning of the passenger activity area in the bullet train on the premise of ensuring structural strength and functionality.

[0041] According to an implementation manner provided by an embodiment of the present application, at least one mounting plate 330 is clamped between the fixed plates 320. The mounting plate 330 is used for mounting a light strip, and the length of the mounting plate 330 is L, satisfying 52 mm > L > 48 mm.

[0042] It should be noted that in the implementation manner provided by the embodiment of the present application, the length L of the mounting plate 330 is 49 mm to adapt to the width of the light strip, avoid excessive redundancy of the mounting plate 330, and reduce the cost of producing the profile plate 300. The light strip is fixedly connected to the mounting plate 330 by means of bolts. Since the entire profile plate 300 is an integrated structure, the mounting plate 330 is seamlessly connected to the two fixed plates 320. Chamfers are provided at the connection between the mounting plate 330 and the two fixed plates 320, and the radius of the chamfer is set to 3 mm. The triangular structure formed by enclosing multiple fixed plates 320 and the mounting plate 330 further enhances the structural strength of the profile plate 300 and reduces the unstable factors caused by vibration during the running of the bullet train.

[0043] According to an implementation manner provided by an embodiment of the present application, the profile plate 300 is connected to the inner wall 100 and the decorative plate 400 by bolts respectively. The decorative plate 400 has an extension plate extending downward. Part of the extension plate approaches the inner wall 100, and the extension plate is connected with a mounting component 500. Part of the mounting component 500 is buried in the inner wall 100.

[0044] It should be noted that part of the installation component 500 is arranged inside the inner wall 100, and the installation component 500 exposed outside the inner wall 100 includes a bent plate. There are holes in the bent plate, and the holes are correspondingly arranged with the extended plate extending downward from the decorative plate 400. The extended plate has a part protruding toward the inner wall 100, and there are also holes in the protruding part. The holes here correspond to the holes in the bent plate. Only one bolt is needed to complete the positioning installation under the installation component 500 and the decorative plate 400. Compared with the traditional installation method, it is more convenient and does not require precise positioning in multiple places, improving the installation efficiency.

[0045] According to an implementation manner provided by an embodiment of the present application, a folding plate 410 is arranged at one end of the decorative plate 400 away from the extended plate. The folding plate 410 is connected to the fixing plate 320 by bolts, and the folding plate 410 can rotate relative to the fixing plate 320.

[0046] It should be noted that the folding plate 410 part includes a protruding handle part, which is connected to the bent part of the folding plate 410. By rotating the handle part, the bent part can rotate relative to the main body part of the decorative plate 400, so as to realize the ability to adjust the inclination angle of the decorative plate 400 at any time. The angle change of the decorative plate 400 can offset part of the vibration generated during the movement of the bullet train, and the decorative plate 400 can freely adjust the angle, improving the installation efficiency.

[0047] In addition, when the bullet train encounters vibrations of different degrees, such as the instantaneous impact generated when passing through a turnout, the staff can quickly rotate the handle part according to the actual situation. Since the handle part is connected to the bent part of the folding plate 410, rotating the handle can drive the bent part to rotate relative to the main body part of the decorative plate 400, so as to flexibly adjust the inclination angle of the decorative plate 400. This can not only effectively offset the vibration generated during the movement of the bullet train and ensure the comfort of passengers, but also bring more possibilities for the space utilization inside the bullet train. For example, when it is necessary to adjust the visual effect or lighting angle inside the carriage, the inclination of the decorative plate 400 can be changed at any time to meet different needs.

[0048] On the other hand, the decorative plate 400 can be freely adjusted in angle, so that the installation process of the profile plate 300 no longer requires extremely high-precision alignment. This greatly reduces the installation difficulty and shortens the installation time. In the EMU assembly workshop, workers do not need to spend a lot of time and effort to repeatedly calibrate the position. After only a preliminary positioning, by adjusting the angle of the folding plate 410, the decorative plate 400 can be perfectly matched with other components. Moreover, this design also improves the efficiency of equipment maintenance. When the decorative plate 400 or related components need to be repaired or replaced, by rotating the folding plate 410, it can be easily disassembled and installed, reducing the maintenance cost and time cost caused by complex installation, and further ensuring the normal operation of the EMU. In addition, the handle part of the folding plate 410 is simple and convenient to operate. Even during the operation of the EMU, the staff can easily perform the adjustment operation.

[0049] According to an embodiment provided by the present application, the thickness of the arc-shaped plate 310 is d1, satisfying 4mm > d1 > 2mm.

[0050] It should be noted that in the embodiment provided by the present application, the arc-shaped plate 310 partially bends and extends from the upper part of the fixed plate 320 on the side close to the inner wall 100 towards the top plate 200. The thickness of the body part of the arc-shaped plate 310 is about 2mm, and the thickness of the arc-shaped plate 310 near the end part is about 4mm. In order to better adapt to the abutting relationship with the top plate 200, the inner diameter of the arc-shaped plate 310 near one end of the fixed plate 320 is 40mm, and the inner diameter of the arc-shaped plate 310 extending to the middle position is 91mm. And the arc-shaped plate 310 is made of aluminum profile and has good bending ability, and can be adjusted according to the height of the top plate 200.

[0051] According to an embodiment provided by the present application, a groove is opened at one end of the arc-shaped plate 310 away from the fixed plate 320, and a rubber strip 321 is installed in the groove, and one end of the rubber strip 321 abuts against the top plate 200.

[0052] It should be noted that the groove part has the characteristic of being narrow at the top and wide at the bottom, making it difficult for the inserted rubber strip 321 to come out. In other embodiments, the groove may not be set in this structure, as long as the rubber strip 321 installed in the groove part will not come out due to the vibration brought by the movement of the bullet train. The rubber strip 321 plays multiple key roles. When the device is subjected to external vibration, the rubber strip 321, relying on its good elasticity, can effectively buffer the impact force brought by the vibration, avoiding wear or damage caused by rigid collision between the arc-shaped plate 310 and the top plate 200, and greatly extending the service life of each component of the device. At the same time, the rubber strip 321 also has excellent sealing performance, which can prevent foreign matters such as dust and impurities from entering the device interior from the connection between the arc-shaped plate 310 and the top plate 200, ensuring the cleanliness of the device interior environment, and thus guaranteeing the stable operation of the device. The rubber strip 321 can also block noise to a certain extent, reducing the impact of the noise generated during the operation of the device on the surrounding environment, and creating a quieter and more comfortable use environment for users. Moreover, during the device assembly process, the presence of the rubber strip 321 makes the installation of the arc-shaped plate 310 and the top plate 200 more convenient. The installation personnel do not need to spend too much energy to adjust the fitting accuracy between the two, improving the production efficiency and reducing the production cost.

[0053] According to an implementation manner provided by an embodiment of the present application, a part of the rubber strip 321 is disposed outside the groove of the fixing plate 320, and the thickness of the part of the rubber strip 321 exceeding the groove is d2, satisfying d2≥1mm.

[0054] It should be noted that a part of the rubber strip 321 is disposed outside the groove of the fixing plate 320, and it is specified that the thickness d2 of the part exceeding the groove is d2≥1mm. When d2 reaches this standard, it can ensure that the rubber strip 321 can maintain sufficient elasticity and buffering performance even under repeated extrusion and friction during long-term use. In the working environment where the bullet train vibrates frequently, the thicker exceeding part can effectively reduce the elastic attenuation caused by material fatigue, ensure its continuous buffering effect, and avoid damage to the device due to vibration. Moreover, such a thickness design also enhances the sealing performance, preventing the problem of reduced sealing performance due to compression deformation of the rubber strip during long-term use, and ensuring that the device interior is always in a good protection state. A thickness not less than 1mm is also convenient for production processing and installation operations. If the thickness is too thin, it is easy to break or shift during the installation process, affecting the overall assembly quality and device performance. In addition, when the device needs maintenance or component replacement, the rubber strip 321 that meets this thickness requirement is easier to disassemble and replace, reducing the maintenance cost and time cost, and further improving the maintainability of the device.

[0055] According to an implementation manner provided by an embodiment of the present application, the present application provides a light strip profile, and the light strip profile is composed of a plate body provided by an embodiment of the present application.

[0056] It should be noted that for the light strip profile based on the board design, its installation and disassembly processes are extremely simple. Workers can quickly complete the connection and separation between the boards with the help of simple tools. Compared with the traditional installation structure, the construction time is greatly shortened and the work efficiency is improved. At the same time, the appearance design of this light strip profile also fully considers aesthetics and comfort. Its surface is smooth and flat, and the light transmission is uniform and soft, which can create a warm and comfortable riding environment for passengers and further improve the overall quality of the EMU. Moreover, the modular light strip profile is convenient for later maintenance and component replacement. When a fault occurs in a certain part, the corresponding module can be directly disassembled for repair or replacement, effectively reducing the maintenance cost and time and ensuring the normal operation of the EMU.

[0057] After considering the specification and practicing the invention disclosed herein, those skilled in the art will readily conceive of other embodiments of the present application.
