Description

Technical Field

[0001] This application relates to the field of rail transit technology, and in particular to an integrated side wall panel, a car body side wall, a car body, and a train. Background Technology

[0002] With the rapid development of high-speed rail technology, the safety, comfort, and ease of maintenance of high-speed trains have become important indicators for evaluating their performance. As a crucial component of the train, the sidewalls not only protect the interior environment and passenger safety but also directly affect the vehicle's weight and energy consumption. Traditional train sidewall designs typically manufacture and install the window panels and the panels below the windows separately. While this separate design meets structural requirements to some extent, it has gradually revealed limitations in practical applications.

[0003] Existing side wall panel designs for high-speed trains have several significant drawbacks. First, the separate window and lower window panels require installation at multiple fixing points, increasing installation complexity and time costs, and potentially leading to stress concentration at structural joints, impacting vehicle durability. Second, maintenance of the roller shutters or window glass necessitates the removal of the entire window panel, a time-consuming and labor-intensive process that may damage surrounding structures. Furthermore, traditional designs fall short in terms of aesthetics and weight reduction, failing to meet the dual demands of modern high-speed trains for lightweight construction and aesthetics. Therefore, an innovative side wall panel design is urgently needed to address these issues and improve the overall performance of high-speed trains. Summary of the Invention

[0004] The purpose of this application is to provide an integrated sidewall panel. This integrated design effectively simplifies the installation process of the train's sidewall, improves maintenance efficiency, and facilitates the inspection and maintenance of the roller shutters and windows through a detachable interior frame design.

[0011] In some embodiments, a pair of air ducts are provided on the window wall panel and the lower window wall panel, the air ducts are vertically arranged, and the interior frame is provided between the pair of air ducts; and / or,

[0012] The window wall panel is equipped with an ambient light fixture, which includes a snap-fit ​​cover plate that is detachably connected to the window wall panel.

[0013] This application also provides a vehicle body sidewall, including a top structure, a bottom structure, a window, and the aforementioned integrated sidewall panel. The window is located at a window mounting position, the window wall panel is connected to the top structure, and the window bottom wall panel is connected to the bottom structure.

[0014] In some embodiments, the window wall panel is provided with a second locking structure, and the window wall panel is locked and fixed to the top structure through the second locking structure; the lower window wall panel is provided with a second insertion structure, and the lower window wall panel is inserted and positioned to the bottom structure through the second insertion structure; and / or,

[0017] This application also provides a vehicle body, including the aforementioned vehicle body sidewall.

[0018] This application also provides a train, including the aforementioned car body.

[0019] Compared to the aforementioned background technology, the integrated side wall panel provided in this application includes an interior trim assembly, a window wall panel body and a window lower wall panel body that are integrally molded. The window wall panel body is used to connect to the top of the vehicle side wall, and the window lower wall panel body is used to connect to the bottom of the vehicle side wall. The window wall panel body is provided with a window mounting position for installing a window. The interior trim assembly includes an interior trim frame with an integrated roller blind device. The interior trim frame is detachably connected to the window wall panel body. The interior trim frame surrounds the edge of the window mounting position, and the roller blind device is located at the top of the window mounting position.

[0020] In traditional EMU side wall panel designs, window panels and lower window panels are typically installed as independent components. This not only increases the complexity of the installation process but may also lead to structural weaknesses due to the presence of multiple connection points. Furthermore, maintenance of the roller shutter system and windows often requires the removal of the entire window panel, a process that is not only time-consuming but may also damage the surrounding structure, affecting the maintenance efficiency and operational reliability of the EMU.

[0021] To address these shortcomings, the integrated sidewall panel provided in this application employs an innovative one-piece molding design, combining the window panel and the lower window panel into one unit. This simplifies the installation process, reduces connection points, and thus improves the structural integrity and reliability. The window panel is connected to the top of the vehicle body sidewall, and the lower window panel is connected to the bottom. This design not only reduces installation steps but also mitigates potential structural weaknesses by minimizing connection points.

[0022] Equally important, the interior trim component in this technical solution includes an interior frame integrating a roller blind device, which is detachably connected to the window wall panel. This design allows maintenance personnel to directly inspect the roller blind device and the window without disassembling the entire window wall panel, greatly improving the convenience and efficiency of maintenance. Furthermore, the interior frame is positioned around the edge of the window mounting location, with the roller blind device located at the top of the window mounting location. This layout not only makes the side wall panel look cleaner and more aesthetically pleasing but also enhances the overall integrity of the vehicle's side walls, improving the passenger's visual experience.

[0023] Based on the above structural and process descriptions, it can be seen that the integrated side wall panel has at least the following beneficial effects: By adopting an integrated side wall panel design, the installation process of the EMU side wall is effectively simplified, maintenance efficiency is improved, and the detachable interior frame design facilitates the inspection and maintenance of the roller shutter device and windows, while also enhancing the aesthetics and integrity of the car body side wall.

[0048] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0049] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0050] Please refer to Figures 1 to 4 ,in, Figure 1 This is a schematic diagram of an integrated sidewall panel provided in an embodiment of this application. Figure 2 This is an installation diagram of the integrated sidewall panel provided in an embodiment of this application. Figure 3 This is a front view of the integrated sidewall panel provided in an embodiment of this application. Figure 4 This is a front view of the interior frame provided in an embodiment of this application.

[0051] In a first specific embodiment, the integrated side wall panel 100 provided in this application includes an interior component 3, a window wall panel 1 and a lower window wall panel 2, which are integrally formed. The window wall panel 1 is connected to the top structure 7 of the vehicle side wall 200, and the lower window wall panel 2 is connected to the bottom structure 8 of the vehicle side wall 200. The window wall panel 1 is provided with a window mounting position 11, which is used to install a window 6. The interior component 3 includes an interior frame 31 that integrates a roller blind device 32. The interior frame 31 is detachably connected to the window wall panel 1. The interior frame 31 surrounds the edge of the window mounting position 11, and the roller blind device 32 is located at the top of the window mounting position 11.

[0052] In traditional EMU side wall panel designs, the window wall panel 1 and the lower window wall panel 2 are usually installed as independent components. This not only increases the complexity of the installation process but may also lead to structural weaknesses due to the presence of multiple connection points. Furthermore, maintenance of the roller shutter device 32 and the window 6 often requires disassembling the entire window wall panel 1. This process is not only time-consuming but may also damage the surrounding structure, affecting the maintenance efficiency and operational reliability of the EMU.

[0053] To address these shortcomings, the integrated side wall panel 100 provided in this application adopts an innovative one-piece molding design, combining the window wall panel 1 and the lower window wall panel 2 into one unit. This simplifies the installation process, reduces connection points, and thus improves the structural integrity and reliability. The window wall panel 1 is connected to the top structure 7 of the vehicle body side wall 200, and the lower window wall panel 2 is connected to the bottom structure 8. This design not only reduces installation steps but also reduces potential structural weaknesses by minimizing connection points.

[0054] Equally important, the interior component 3 in this technical solution includes an interior frame 31 integrating a roller blind device 32, which is detachably connected to the window wall panel 1. This design allows maintenance personnel to directly inspect the roller blind device 32 and the window 6 without disassembling the entire window wall panel 1, greatly improving the convenience and efficiency of maintenance. Meanwhile, the interior frame 31 is positioned around the edge of the window mounting position 11, and the roller blind device 32 is located at the top of the window mounting position 11. This layout not only makes the appearance of the integrated side wall panel 100 neater and more aesthetically pleasing but also enhances the overall integrity of the vehicle side wall 200, improving the visual experience for passengers.

[0055] Based on the above structural and process descriptions, it can be seen that the integrated side wall panel 100 has at least the following beneficial effects: by adopting an integrated side wall panel design, the integrated side wall panel 100 effectively simplifies the installation process of the EMU side wall, improves maintenance efficiency, and facilitates the maintenance of the roller shutter device 32 and the window 6 through the design of the detachable interior frame 31, while enhancing the aesthetics and integrity of the car body side wall 200.

[0056] Please continue to refer to this. Figure 1 It should be noted that the distinction between window wall panel 1 and window bottom wall panel 2 is based on their functionality rather than their structure. In other words, window wall panel 1 and window bottom wall panel 2 are not two independent panel structures, but a complete panel structure. The difference between the two is that the functions of window wall panel 1 and window bottom wall panel 2 are different.

[0057] In this embodiment, although the window wall panel 1 and the lower window wall panel 2 are functionally distinct, they are actually a unified panel structure rather than two separate parts. This design means that during manufacturing and installation, it is not necessary to physically connect the two separate panels, thereby reducing seams and potential weaknesses.

[0058] The window wall panel 1 is primarily responsible for supporting and carrying the vehicle window 6. It has a window mounting position 11, which is specifically designed for installing the vehicle window. The lower window wall panel 2 is located below the window wall panel 1 and can perform different functions, such as providing additional structural support or installing other components. Despite their different functions, the window wall panel 1 and the lower window wall panel 2 are physically continuous, and together they constitute the integral part of the one-piece side wall panel 100.

[0059] This integrated design allows the window wall panel 1 and the lower window wall panel 2 to be manufactured as a single unit, simplifying the manufacturing process and reducing assembly steps and required connectors during installation. This design not only improves production efficiency but also contributes to enhancing the overall structural stability and durability.

[0060] Furthermore, since the window wall panel 1 and the lower window wall panel 2 are continuous panel structures, no additional sealing or connection measures are required in the transition area between them. This helps reduce maintenance workload and improves the airtightness and watertightness of the integrated side wall panel 100. Overall, this design maintains the simplicity of the structure while meeting the functional and aesthetic requirements of the EMU side wall.

[0061] Optionally, the window wall panel 1 is provided with two coat hooks 13, which are distributed on the left and right sides of the window mounting position 11.

[0062] Please refer to Figure 6 , Figure 7 and Figure 9 ,in, Figure 6 This is an installation diagram of the top of the interior trim frame provided in an embodiment of this application. Figure 7 This is an installation diagram of the bottom of the interior trim frame provided in an embodiment of this application. Figure 9 This is an installation diagram of the side of the interior frame provided in an embodiment of this application.

[0063] In some embodiments, the interior frame 31 is provided with a first insertion structure 311 and a first locking structure 312. The interior frame 31 is inserted and positioned with the window wall panel 1 through the first insertion structure 311, and the interior frame 31 is locked and fixed with the window wall panel 1 through the first locking structure 312.

[0064] In this embodiment, the interior trim frame 31 is designed to be inserted and positioned into the window wall panel 1 via a first insertion structure 311. This insertion structure 311 can be located at multiple positions on the interior trim frame 31, such as the top, bottom, side, or any other suitable location, to ensure that the interior trim frame 31 is accurately aligned with the corresponding part on the window wall panel 1 during installation. Once the interior trim frame 31 is correctly positioned via the first insertion structure 311, the first locking structure 312 further secures the interior trim frame 31, ensuring its stability and firmness on the window wall panel 1.

[0065] Since the exact locations of the first insertion structure 311 and the first locking structure 312 are not specifically defined, this provides design flexibility, allowing the optimal placement of these structures to be determined based on actual installation requirements and the geometry of the integrated sidewall panel 100. For example, the first insertion structure 311 can be located on any side or corner of the interior frame 31 for quick positioning, while the first locking structures 312 can be distributed along the edges of the interior frame 31 to provide uniform fixing force.

[0066] The advantage of this design is that it allows installers to quickly position the interior trim frame 31 using the first insertion structure 311, and then precisely lock it in place using the first locking structure 312. This step-by-step installation method not only improves installation efficiency but also helps reduce potential errors during installation, ensuring a firm and stable connection between the interior trim frame 31 and the window wall panel 1. Furthermore, this design simplifies the disassembly process, facilitating future maintenance or replacement work.

[0067] It should be noted that this embodiment does not specifically limit the implementation of the first insertion structure 311 and the first locking structure 312. This flexibility allows designers to choose the most suitable positioning and fixing method according to the specific needs of the interior frame 31 and the window wall panel 1.

[0068] The design of the positioning structure can be diversified. For example, the interior frame 31 can be designed with specific slots, which can be straight lines or grooves of a specific shape, for engaging with a latch. When the latch is inserted into the slot, the interior frame 31 can be effectively positioned in the desired position on the window wall panel 1. This positioning method is simple and effective, allowing for rapid installation while ensuring the accuracy and repeatability of the positioning.

[0069] The locking structure also has multiple implementation possibilities. Holes can be designed into the interior frame 31 and the window panel 1; these holes can be circular or any shape suitable for bolts to pass through. Through these holes, a combination of bolts and nuts can be used to secure the interior frame 31, ensuring its stability on the window panel 1. This locking method not only provides strong fixing force but also allows for convenient disassembly and reinstallation when needed.

[0070] The advantage of this design approach lies in its adaptability to different installation environments and requirements. It can meet the needs of both rapid assembly during production and easy disassembly during maintenance. At the same time, standardized bolt and nut assemblies help reduce production costs and improve assembly efficiency.

[0071] In summary, this installation design of the interior frame 31, by providing diverse positioning and locking options, not only enhances the functionality and reliability of the integrated sidewall panel 100, but also improves its adaptability in practical applications and ease of maintenance.

[0072] Optionally, the first plug-in structure 311 is a positioning plate with a groove. Corresponding to the positioning plate and its groove, the window wall panel 1 is provided with a connecting plate 14 for installing the pin 15. The pin 15 cooperates with the groove, and the plug-in positioning is achieved by inserting the pin 15 into the groove.

[0073] In some embodiments, the top and left and right sides of the interior frame 31 are provided with a first insertion structure 311, the top and two sides of the interior frame 31 are inserted and positioned with the window wall panel 1, and the bottom of the interior frame 31 is provided with a first locking structure 312, the bottom of the interior frame 31 is locked and fixed with the window wall panel 1.

[0074] In this embodiment, the interior frame 31 is designed to fit in all directions with the window wall panel 1. (See reference...) Figure 6 and Figure 9 The interior frame 31 is equipped with a first insertion structure 311 on its top and both sides. This design allows the interior frame 31 to be effectively inserted and positioned at corresponding locations on the window wall panel 1. The insertion structures 311 on the top and sides not only ensure the horizontal stability of the interior frame 31, but also provide vertical fixation, enabling the entire interior frame 31 to fit tightly against the window wall panel 1, thereby enhancing the overall structural stability and the neatness of the appearance.

[0075] Further, refer to Figure 7The bottom of the interior frame 31 is designed with a first locking structure 312. This structure is combined with the corresponding part on the window wall panel 1, and the bottom of the interior frame 31 is locked and fixed by a combination of bolts and nuts or other similar fastening methods. The bottom locking structure 312 provides additional fixing force to the interior frame 31, ensuring its stability and durability in long-term use and preventing displacement due to vibration or external forces.

[0076] In summary, the all-around fixing design of the interior frame 31 not only improves the fit with the window wall panel 1, but also enhances the structural integrity of the entire integrated side wall panel 100. Through the top and side plug-in structures 311 and the bottom locking structure 312, the interior frame 31 can be firmly installed on the window wall panel 1, providing a side wall solution that is both aesthetically pleasing and practical for the EMU.

[0077] Please refer to Figure 5 , Figure 5 A side view of the interior frame provided in an embodiment of this application.

[0078] In some embodiments, the interior frame 31 also integrates a window sill 33, which is located at the bottom edge of the window mounting position 11.

[0079] In this embodiment, the interior frame 31 is designed to further expand its functionality by integrating a window sill 33 to enhance the practicality of the integrated side wall panel 100. The window sill 33 is cleverly positioned at the bottom edge of the window mounting position 11, a layout that not only effectively utilizes space but also provides additional convenience for passengers. When passengers need to place small items or take a short rest, the window sill 33 can serve as a support platform, increasing the comfort and convenience of the ride.

[0080] Furthermore, the design of the window sill 33 also considers its coordination with the overall style of the interior frame 31, ensuring the aesthetic appeal of the integrated side wall panel 100. The integrated design of the window sill 33 reduces the need for additional components, simplifies the installation process, and also reduces maintenance costs. This design reflects the design philosophy of the interior frame 31, which, while fulfilling its functionality, also emphasizes details and user experience.

[0081] Please continue to refer to this. Figure 5 In some embodiments, the interior frame 31 also integrates a roller blind track 34, which is located on the left and right sides of the window mounting position 11. The roller blind device 32 includes a roller blind roller 321 and a roller blind 322. The roller blind roller 321 is located on the top edge of the window mounting position 11, and the left and right sides of the roller blind 322 are located on the roller blind track 34.

[0082] In this embodiment, the interior frame 31 is designed to further highlight its versatility by integrating a roller blind track 34 to facilitate the use of the roller blind device 32. The roller blind track 34 is carefully positioned along the edges of the left and right sides of the window mounting position 11, providing guidance for the smooth operation of the roller blind 322. This design not only ensures the smooth operation of the roller blind device 32 but also makes the raising and lowering of the roller blind more orderly and convenient.

[0083] The roller blind assembly 32 consists of a roller blind shaft 321 and a roller blind 322. The roller blind shaft 321 is located at the top edge of the window mounting position 11 and is responsible for supporting the roller blind 322 and controlling its opening and closing. The left and right sides of the roller blind 322 slide along the roller blind track 34 to ensure the smoothness and consistency of the roller blind when opening and closing. This design allows the roller blind assembly 32 to be compactly stored when not in use and conveniently opened when needed to provide passengers with privacy or light control.

[0084] Furthermore, the integrated design of the roller shutter slide 34 also considers aesthetics and practicality, coordinating with the overall shape and function of the interior frame 31. This design not only enhances the aesthetics of the integrated side wall panel 100 but also strengthens its practicality, making the interior space of the train more flexible and comfortable. Through this meticulous design, the interior frame 31 and the roller shutter device 32 together provide passengers with a travel environment that is both beautiful and practical.

[0085] Please continue to refer to this. Figure 5 and Figure 6 In some embodiments, the roller blind device 32 includes a roller blind roller 321 and a roller blind 322; the interior trim assembly 3 also includes a roller blind cover 35, which is connected to the window wall panel 1. The roller blind cover 35 is curved and the roller blind cover 35 and the window wall panel 1 enclose a protective space for accommodating the roller blind roller 321, the area where the roller blind roller 321 and the roller blind 322 meet, and at least a portion of the back area of ​​the roller blind 322.

[0086] In this embodiment, the design of the roller blind device 32 places particular emphasis on its coordination and protection with the integrated side wall panel 100. The roller blind device 32 consists of a roller blind roller 321 and a roller blind 322, which work together to unfold and retract the blind. To ensure smooth and safe operation of the roller blind device 32, the interior trim assembly 3 also includes a roller blind cover 35.

[0087] The roller blind cover 35 is ingeniously designed. It is connected to the window wall panel 1 and is curved, forming a protective space together with the window wall panel 1. The main purpose of this protective space is to prevent the roller blind device 32 from structurally interfering with other components during operation. Specifically, when the roller blind 322 unfolds or retracts from the roller blind roller 321, the roller blind cover 35 can protect the roller blind roller 321, the area where the roller blind roller 321 meets the roller blind 322, and at least part of the back area of ​​the roller blind 322, preventing them from colliding or rubbing against other structures on the side wall panel.

[0088] This design not only provides effective physical protection for the roller shutter device 32, but also ensures its operational reliability and the overall aesthetic appeal of the integrated sidewall panel 100. The presence of the roller shutter cover 35 reduces potential obstacles encountered during use, thereby lowering maintenance costs and extending its service life. Furthermore, this design helps maintain a clean and orderly interior, providing passengers with a more comfortable and safer travel environment.

[0089] Optionally, the function of the roller shutter cover 35 is to prevent the back insulation material from interfering with the rotation of the roller shutter shaft 321.

[0090] In some cases, the working process of roller blind 322 and roller blind roller 321 is described as follows.

[0091] In this embodiment, the working principle and workflow of the roller blind device 32 are carefully designed to ensure its efficient and smooth operation, and to work in conjunction with other structures of the integrated sidewall panel 100. The core components of the roller blind device 32 are the roller blind roller 321 and the roller blind 322.

[0092] The roller blind spool 321 is mounted on the top edge of the window mounting position 11. This position ensures that the spool does not occupy extra space when rolling up or releasing the blind 322, and also facilitates passenger operation. The design of the roller blind spool 321 allows the blind 322 to be smoothly rolled up and unrolled on it.

[0093] The roller blind 322 is connected to the roller blind shaft 321, and its design typically incorporates a degree of flexibility and strength to facilitate rolling on the shaft without easily being damaged. The left and right sides of the roller blind 322 slide along roller blind tracks 34, which are located along the left and right edges of the window mounting position 11. This design ensures linear movement of the roller blind 322 during opening and closing, reducing friction and wear, and also making the opening of the roller blind more even and aesthetically pleasing.

[0094] When the roller blind device 32 needs to be unfolded, the roller blind 322 is gradually released from the roller blind roller 321 and unfolds downwards along the roller blind slide 34 until it completely covers the window mounting position 11, providing passengers with privacy protection or light blocking function. During the unfolding process of the roller blind 322, the roller blind cover 35 plays a key role. The protective space formed by the roller blind cover 35 and the window wall panel 1 not only protects the connection area between the roller blind roller 321 and the roller blind 322, but also covers the back area of ​​the roller blind 322, preventing the roller blind from interfering with other components during movement and ensuring the smooth operation of the roller blind device 32.

[0095] Furthermore, the design of the roller blind cover 35 also takes into account preventing interference between the back insulation material or other materials and the roller blind shaft 321, ensuring the free and unobstructed rotation of the shaft. This comprehensive design not only improves the performance of the roller blind device 32, but also enhances the overall functionality and aesthetics of the integrated side wall panel 100.

[0096] Throughout the operation of the roller blind assembly 32, the relative positions and synergistic effects of the various components are crucial.

[0106] Optionally, the window wall panel 1 features an innovative structural layout, consisting of two parts: a vertical section connected to the lower window wall panel 2, and an inclined section extending upwards from the vertical section and curving towards the horizontal. This design not only visually enhances the three-dimensionality of the side wall panel but also provides a more optimized solution for interior lighting.

[0107] The ambient lighting fixtures 5 are cleverly positioned on the sloping portion of the window panel 1. This layout offers several significant advantages. First, because the fixtures 5 are located on the sloping portion, their light can be distributed more widely throughout the cabin, reducing blind spots and improving overall lighting performance. Second, the sloping position allows the light emitted by the fixtures to illuminate the passenger area more evenly, avoiding glare that might be caused by direct downward illumination, thus providing passengers with a more comfortable visual experience. Furthermore, the ambient lighting fixtures 5 positioned on the sloping portion also enhance the aesthetics of the interior. The design of the fixtures harmonizes with the curves of the sloping portion, becoming a decorative feature of the side panel, while the emitted light creates a warm and welcoming atmosphere inside the cabin.

[0108] This application also provides a vehicle body side wall 200, including a top structure 7, a bottom structure 8, a window 6 and the aforementioned integrated side wall panel 100. The window 6 is located at the window mounting position 11. The window wall panel 1 is connected to the top structure 7, and the window lower wall panel 2 is connected to the bottom structure 8.

[0109] The vehicle body side wall 200 should have all the beneficial effects of the aforementioned integrated side wall panel 100.

[0110] In this embodiment, the design of the vehicle side wall 200 embodies an innovative integration method. By integrating the window wall panel 1 and the lower window wall panel 2 into a unified structure, this application eliminates the traditional central fixing point. The top of the window wall panel 1 is fixed to the top structure 7, while the lower part of the lower window wall panel 2 is connected to the bottom structure 8 via a plug-in connection.

[0111] In addition, an interior frame 31 is provided in the middle of the window wall panel 1. This interior frame 31 not only serves a decorative purpose but also integrates the function of a roller blind device 32. The design of the interior frame 31 allows for easy disassembly, which not only facilitates the inspection and maintenance of the roller blind shaft 321 but also allows for the removal of the interior components 3 and the repair of the window 6 when necessary, such as removing the glass, greatly facilitating maintenance and repair work.

[0112] This design solves the problem of difficult maintenance of the roller shutter shaft 321 and the window 6. The integrated design of the window wall panel 1 and the lower window wall panel 2 not only improves the aesthetics of the passenger interface, but also achieves weight reduction by eliminating the top and middle fixing points, which helps to improve the overall performance and energy efficiency of the EMU.

[0113] Please refer to Figure 11 and Figure 12 , Figure 11 This is an installation diagram of the top of the integrated sidewall panel provided in an embodiment of this application. Figure 12 An installation diagram of the bottom of the integrated sidewall panel provided in an embodiment of this application.

[0114] In some embodiments, the window wall panel 1 is provided with a second locking structure 12.

The window lower wall panel 2 is inserted and positioned to the bottom structure 8 through the second insertion structure 21.

[0115] In this embodiment, the connection method of the integrated side wall panel 100 is further optimized to enhance the structural stability and ease of installation of the integrated side wall panel 100. A second locking structure 12 is specially designed for the window wall panel 1, which enables the window wall panel 1 to be locked and fixed to the top structure 7. This locking method not only ensures a firm connection between the window wall panel 1 and the top structure 7, but also simplifies the installation process and improves the overall structural stability.

[0116] Meanwhile, the lower wall panel 2 is designed with a second insertion structure 21, which allows the lower wall panel 2 to be inserted and positioned with the bottom structure 8. Through the second insertion structure 21, the lower wall panel 2 can be precisely aligned and fixed with the bottom structure 8. The insertion positioning and locking fixation work together to ensure the stable installation of the integrated side wall panel 100, and quick installation can be achieved without complicated installation steps.

[0117] This design eliminates the traditional central fixing point. The upper part is fixed to the top structure 7 via the second locking structure 12, while the lower part is connected to the bottom structure 8 via the second plug-in structure 21. This design not only improves the aesthetics of the passenger interface but also achieves weight reduction of the integrated side wall panel 100 by reducing the number of fixing points, which helps to improve the overall performance of the EMU.
