[0026] An integrated modular structure for the top of a ventilation duct in a rail vehicle, such as Figure 1 , 2As shown in Figures 3 and 4, the module includes a first top module 1, a second top module 2, a third top module 3, a fourth top module 4, and a fifth top module 5. Each module has a top plate 6, a grille 7, and an air duct body 8 at its bottom. The top plate 6, the grille 7, and the air duct body 8 are fixed to the longitudinal beams 10 on both sides by a mounting frame 9. The modules are fixedly connected. The first top module 1 and the second top module 2 are located in the middle of the entire integrated module. The third top module 3 and the fourth top module 4 are located on opposite sides of the first top module 1 and the second top module 2, respectively. The fifth top module 5 is located on the other side of the third top module 3. A pair of... A corner partition 11 is provided, which diagonally divides the left and right spaces. An air inlet flexible air duct 12 is provided above both ends of the first top module 1 and the second top module 2. The air duct body 8 located behind the air inlet flexible air duct 12 at both ends of the first top module 1 and the second top module 2 is separated into upper and lower spaces by a sound-absorbing partition 13. It forms a return air duct 15 and a sound-absorbing air duct 16 with a sound-absorbing guide module 14 provided behind the sound-absorbing partition 13. The sound-absorbing guide module 14 has gaps on its outer side, which are connected to the left and right spaces separated by the diagonal partition 11. The sound-absorbing air duct 16 at one end of the first top module 1 and the second top module 2 is connected to the return air duct 15 at the other end through the diagonal partition 11.

[0027] Specifically, by integrating the air duct, soundproofing, roof panel, grille, and light fixture mounting profiles into each top module, modular assembly is achieved, improving installation efficiency. The modules are fixedly connected, forming a unified top integrated modular structure. This optimizes the air duct layout, reduces assembly steps and complexity, and a diagonal partition 11 is placed at the connection between the first top module 1 and the second top module 2, obliquely separating the left and right spaces, enhancing airflow organization within the air duct and improving ventilation efficiency. The flexible air inlet duct 12 allows air to enter the air duct body more smoothly. 8. The sound-absorbing baffle 13 effectively separates part of the upper and lower spaces, reducing noise transmission. The sound-absorbing airflow guiding module 14 not only plays a guiding role, but also works with the sound-absorbing baffle 13 to form the return air duct 15 and the sound-absorbing air duct 16, further improving the ventilation effect and sound absorption performance. The sound-absorbing air duct 16 is connected to the return air duct 15 through the diagonal baffle 11, forming a complex and effective airflow path, which not only meets the ventilation requirements, but also achieves a good sound absorption effect. The design of the entire top integrated modular structure makes the loading process simpler and faster, and greatly improves production efficiency.

[0028] As a preferred embodiment of the above, such as Figure 7As shown, the modules are fixedly connected by screws and nuts with aluminum profile flange frames 17, and the ends of each top plate 6 and the aluminum profile flange frames 17 are sealed with sealing foam.

[0029] Specifically, the modules are fixedly connected by screws and nuts with aluminum profile flange frame 17, which facilitates disassembly and reinstallation, and is beneficial for subsequent maintenance and upgrades. The use of sealing foam ensures the sealing between the ends of each top plate 6 and the aluminum profile flange frame 17, effectively preventing air leakage and noise transmission, and improving the ventilation efficiency and noise reduction performance of the entire system.

[0030] As a preferred embodiment of the above, such as Figure 6 As shown, the air inlet flexible duct 12 adopts a perforated plate with built-in sound-absorbing material.

[0031] Specifically, the use of a perforated plate with built-in sound-absorbing material in the air inlet flexible duct 12 can effectively absorb sound wave energy, reduce noise propagation, and improve the sound absorption performance of the entire system.

[0032] As a preferred embodiment of the above, such as Figure 6 As shown, the air inlet flexible air duct 12 is provided with a heat insulation material interlayer 12-1 and is compensated for in accordance with the vehicle body tolerance.

[0033] Specifically, the insulation interlayer 12-1 effectively reduces the impact of external heat on the interior of the air duct, improves the thermal efficiency of the ventilation system, ensures the stability of the interior temperature, and the design that compensates for the vehicle body tolerance ensures that the soft air duct 12 at the air inlet can fit tightly with the vehicle body during installation, reducing air leakage or poor sealing problems caused by assembly tolerances, and also preventing condensation.

[0034] As a preferred embodiment of the above, such as Figure 3 As shown, the noise reduction and flow guiding module 14 includes a porous noise reduction contact surface 14-1 and a flow guiding channel 14-2, and the porous noise reduction contact surface 14-1 has built-in noise reduction material.

[0035] Specifically, the noise reduction and airflow guiding module 14 integrates two major functions: noise reduction and airflow guiding. The porous noise reduction contact surface 14-1 contains built-in noise reduction material, which effectively absorbs sound wave energy and reduces noise transmission. At the same time, the airflow guiding channel 14-2 ensures smooth airflow and optimizes the airflow distribution within the duct.

[0036] As a preferred embodiment of the above, such as Figure 6 As shown, a portion of the top of the vehicle body in front of the air inlet flexible air duct 12 is cut off and a soft air duct bottom silencing structure 12-2 is installed.

[0037] Specifically, the sound-absorbing structure 12-2 at the bottom of the flexible air duct further enhances the sound absorption capability of the entire air duct system. This sound-absorbing structure can absorb and reflect sound waves, reduce noise propagation, and provide passengers with a quieter riding environment. Removing part of the structure at the top of the vehicle body provides a smoother airflow path for the flexible air duct 12 at the air inlet, reducing air resistance and turbulence during airflow, thereby improving ventilation efficiency.

[0038] As a preferred embodiment of the above, such as Figure 3 As shown, the air duct body 8 is made of silicone tarpaulin.

[0039] As a preferred embodiment of the above, such as Figure 1 As shown, the grille 7 is configured as a double-door structure.

[0040] Specifically, the air duct body 8 uses silicone tarpaulin, which has excellent high and low temperature resistance and can maintain its shape and performance in extreme temperature environments, ensuring that the air duct body 8 can operate stably under various climatic conditions. While ensuring a certain degree of air permeability, the reasonable sealing design also ensures that the air flow inside the air duct body 8 is not disturbed by the outside world, thus improving ventilation efficiency. The double-door grille 7 can be flexibly opened and closed as needed, which is conducive to adjusting the air flow in the air duct and improving ventilation efficiency. This makes opening and closing the grille 7 more convenient and facilitates regular maintenance and cleaning of the air duct, ensuring the normal operation of the ventilation system.

[0041] As a preferred embodiment of the above, such as Figure 1 As shown, the modular assembly is carried out in the following order: through the flexible air ducts 12 at the air inlets on both sides, followed by the first top module 1 and the second top module 2, and finally the third top module 3, the fourth top module 4 and the fifth top module 5.

[0042] Specifically, by setting a pre-defined assembly sequence, it can be ensured that each module is closely and orderly connected during the assembly process, reducing confusion and errors in the assembly process, improving assembly efficiency, and enabling each module to be debugged and maintained independently. The specific assembly sequence also helps to quickly locate problems during debugging and maintenance, thus improving work efficiency.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
