Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0047] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0048] It should be noted that the directional terms such as "upper end, lower end, left side, right side" described below are all defined based on the drawings in the specification.

[0049] Please refer to 1 to Figure 8 , Figure 1 This is a structural diagram of the top module in the carriage in an embodiment of the present application; Figure 2 for Figure 1 The schematic diagram of the connection structure of the top module in the carriage shown; Figure 3 for Figure 2 A schematic diagram of a portion of the structure of the top module in the carriage shown; Figure 4 for Figure 3 Enlarged view of part A in the middle; Figure 5 for Figure 1 A longitudinal section diagram of the top module in the carriage shown; Figure 6 for Figure 1 The schematic diagram of the edge sealing connection of the air duct structure in the top module of the carriage is shown; Figure 7 for Figure 1 Schematic diagram of the installation of television and camera in the top module of the carriage; Figure 8 This is a schematic diagram of the top structure of the carriage in an embodiment of the present application.

[0050] The vehicle compartment mid-top module provided in the embodiment of the present application is used to be installed inside the vehicle body 80 . The vehicle compartment mid-top module includes a mid-top plate 10 , an air duct structure 20 and a plurality of support members 30 .

[0051] Within a railroad train compartment, a center roof panel 10 is located above the interior space of the compartment and in the center of the compartment. The center roof panel 10 is connected to the vehicle body 80 at both ends along a first direction. An air duct structure 20 is integrally mounted on the center roof panel 10 to form an air cavity above the center roof panel 10.

[0052] Each support member 30 is installed between the middle top plate 10 and the air duct structure 20 at intervals along a second direction perpendicular to the first direction to improve the rigidity of the air duct structure 20. Of course, each support member 30 can be a support rod structure.

[0053] It should be noted that the first direction is the width direction of the vehicle body 80 , and the second direction is the length direction of the vehicle body 80 .

[0054] Compared with the traditional center roof panel 10 structure, the center roof module of the car body provided in the embodiment of the present application adopts a design method of integrating the center roof panel 10 and the air duct structure 20, and connects the two ends of the center roof panel 10 to the car body 80, changing the installation structure, eliminating the traditional air duct box structure, air duct installation support beam and air duct installation seat structure, etc., which can minimize the installation space, especially the height space of the roof, reduce the installation process, and greatly reduce the weight of the whole vehicle, thereby realizing the frameless installation of the wide center roof panel 10 integrated with the air duct structure 20.

[0055] In some embodiments, the middle top plate 10 includes a first top plate body 11 and a second top plate body 12 . The first top plate body 11 is provided with a plug-in sealing assembly 13 , and the second top plate body 12 is provided with a socket sealing assembly 14 .

[0056] The plug-in sealing component 13 is plugged into the socket sealing component 14 along the second direction to connect the first top plate body 11 and the second top plate body 12 and seal the gap between the first top plate body 11 and the second top plate body 12 .

[0057] It can be understood that the middle top panel 10 in the car can be formed by splicing two parts, and the plug-in sealing component 13 on the first top panel body 11 is plugged into the socket sealing component 14 on the second top panel body 12. This not only enables the two parts of the top panel body to be connected to form the overall structure of the middle top panel 10, but also enables the gap between the first top panel body 11 and the second top panel body 12 to be sealed, so that the air cavity above the middle top panel 10 is a sealed cavity.

[0058] In some embodiments, the plug-in seal assembly 13 includes a plug-in connector 131 and a first elastic member 132. The first elastic member 132 is adapted to the first top plate body 11 and the plug-in connector 131 so that the first elastic member 132 abuts against at least a portion of the top surfaces of both the first top plate body 11 and the plug-in connector 131. Correspondingly, the socket seal assembly 14 includes a socket member 141 and a second elastic member 142. The socket member 141 is provided with a socket slot 1411 on a side close to the plug-in connector 131. The first elastic body 1421 of the second elastic member 142 is provided in the socket slot 1411. The first elastic body 1421 is used for inserting the plug-in connector 131 and abutting against the first elastic member 132. The second elastic body 1422 of the second elastic member 142 is adapted to the second top plate body 12 and the socket member 141 so that the second elastic body 1422 abuts against at least a portion of the top surface of the second top plate body 12 and the side of the socket member 141 facing away from the socket slot 1411.

[0059] It should be noted that both the first elastic member 132 and the second elastic member 142 can be configured as compressed foam, and the plug-in member 131 and the socket member 141 are both made of aluminum profiles. The plug-in member 131 has a plug-in end facing the socket 1411 of the socket member 141. The plug-in end is inserted into the first elastic body 1421 in the socket 1411. This, on the one hand, achieves a connection between the first top plate body 11 and the second top plate body 12. On the other hand, during the insertion of the plug-in member 131 into the first elastic body 1421, the first elastic member 132 and the second elastic member 142 undergo moderate compression deformation, thereby sealing the gap between the first top plate body 11 and the second top plate body 12.

[0060] In this way, the overlap between the two top plate bodies and the sealing of the air duct are achieved by plugging the structure and compressing the foam. On the one hand, the air duct structure 20 is integrated on the upper part of the middle top plate 10, and the air duct sealing needs to be achieved by compressing the flexible foam. On the other hand, the rigid overlap reduces the deformation of the vehicle body 80 in the height direction, meeting the suspension height requirement of the middle top plate 10.

[0061] In some embodiments, the first elastic member 132 is provided with a first inclined surface 1321, and the second elastic member 142 is provided with a second inclined surface 14221. The slopes of the first inclined surface 1321 and the second inclined surface 14221 can be the same. In addition, the first elastic member 132 is also provided with a horizontal surface 1322, and the horizontal surface 1322 is flush with the top surface of the socket 141. With such a setting, a smooth air duct can be formed in the wind cavity, thereby reducing the wind speed vortex in the wind cavity and facilitating the air flow in the wind cavity.

[0062] In some embodiments, the air duct structure 20 includes a first air duct body 21 and a second air duct body 22 , and the first air duct body 21 and the second air duct body 22 are sealed after being docked along the second direction.

[0063] Specifically, the first air duct body 21 is provided with a first docking member 211, which is provided with a first elastic body 212 and a first adhesive strip 213. The second air duct body 22 is provided with a second docking member 221, which is provided with a second elastic body 222 and a second adhesive strip 223. The first and second docking members 211, 221 are connected by bonding them together using the first and second adhesive strips 213, 223. Simultaneously, when the first and second docking members 211, 221 are docked, the first and second elastic bodies 212, 222 abut against each other and undergo compression deformation.

[0064] That is, after the first adhesive strip 213 and the second adhesive strip 223 are bonded and fixed, the first elastic body 212 and the second elastic body 222 abut against each other and are compressed and deformed, thereby sealing the gap between the first docking piece 211 and the second docking piece 221 and meeting the sealing requirements of the air duct.

[0065] In addition, the outer edges of the first duct body 21 and the second duct body 22 can also be sealed using a rubber strip and an elastomer. Specifically, a third rubber strip 214 and a fourth rubber strip 224 are respectively fixed to the inner sidewalls of the outer edges of the first duct body 21 and the second duct body 22. The third rubber strip 214 and the fourth rubber strip 224 are adhesively fixed to achieve the connection between the outer edges of the first duct body 21 and the second duct body 22. At the same time, a third elastomer 215 and a fourth elastomer 225 are respectively provided on the inner sidewalls of the first duct body 21 and the second duct body 22. The third elastomer 215 and the fourth elastomer 225 are both arranged along the second direction.

[0066] In this way, after the third rubber strip 214 and the fourth rubber strip 224 are bonded and fixed, the third elastomer 215 and the fourth elastomer 225 abut against each other and are compressed and deformed, which can seal the gap between the outer edges of the first air duct body 21 and the second air duct body 22, meeting the sealing requirements of the air duct.

[0067] In some embodiments, mounting seats 40 are provided at both ends of the middle roof panel 10 along the first direction. The mounting seats 40 are used to be connected to the slide grooves of the vehicle body 80 through shock-absorbing bolts 50 .

[0068] In this way, both ends of the middle roof panel 10 along the first direction are connected to the vehicle body 80 via the mounting brackets 40, enabling the middle roof panel 10 to be hoisted at multiple hoisting points. Providing the mounting brackets 40 at both ends of the middle roof panel 10 along the first direction ensures the stability and reliability of the connection between the middle roof panel 10 and the vehicle body 80, thereby ensuring the stability of the air cavity on the middle roof panel 10 during operation.

[0069] In some embodiments, the air duct structure 20 includes a dynamic pressure air duct 23, which includes a top 231 and two side portions 232. The two side portions 232 are respectively arranged on both sides of the top 231 along the first direction to form a dynamic pressure air cavity 233. The two side portions 232 are connected to the middle top plate 10 by bonding and connecting seats (such as angle aluminum).

[0070] In some embodiments, the air duct structure 20 further includes two static pressure air ducts 24, which are respectively arranged on both sides of the dynamic pressure air duct 23 along the first direction to form a static pressure air cavity 241 on both sides of the dynamic pressure air cavity 233 along the first direction. The two static pressure air ducts 24 are connected to the middle top plate 10 by bonding and connecting seats (such as angle aluminum).

[0071] In this way, after the dynamic pressure chamber enters the air, it is supplied to the static pressure chamber through the openings evenly arranged on the facade, and the conversion between reduced wind speed and uniform wind speed is achieved in the static pressure chamber to ensure the uniformity of air supply in the car.

[0072] In addition, a television 60 , a camera 70 , wiring, and a top plate mounting frame may be integrated on the middle top plate 10 .

[0073] The present application provides a carriage, which includes a carriage body 80 and a carriage mid-top module installed in the carriage body 80 as described in the above specific embodiment.

[0074] The present application provides a rail train comprising the carriages described in the above specific embodiments. Other parts of the rail train can refer to related technologies and will not be elaborated herein.

[0075] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0076] The above is a detailed introduction to the carriage top module, carriage, and rail car provided by this application. Specific examples are used herein to illustrate the principles and implementation methods of this application. The description of the above embodiments is only used to help understand the solution and core ideas of this application.
