DETAILED DESCRIPTION

[0026] In order to make the person skilled in the art better understand the present application, the present application will be further described in detail below in combination with the drawings and specific embodiments.

[0027] For the convenience of understanding and description, the following will be described in combination with the rail vehicle and its roof device, and the beneficial effect part will not be repeated.

[0028] The rail vehicle includes a vehicle body, the vehicle body includes a roof device, and the roof device includes a roof panel and a structure for mounting an antenna device. Other structures of the rail vehicle can be realized based on the prior art, and are not the core of the present application, and will not be described in detail here. The specific structure of the roof device will be described below.

[0029] It should be noted that the orientation words "transverse" in this article refer to the direction along the width of the rail vehicle, "longitudinal" refers to the direction along the length of the rail vehicle, "upper" and "lower" are based on the position relationship of the rail vehicle in the normal driving state, and the use of the orientation words is only for the purpose of describing the technical solution clearly and conveniently, and does not constitute a limitation on the protection scope.

[0030] Please refer to Figure 1 and Figure 7 , Figure 1 As Figure 7 As

[0031] In this embodiment, the roof device of the rail vehicle includes a roof plate 10, and further includes a mounting platform 20 and a cover body 30, wherein the mounting platform 20 is fixedly connected with the roof plate 10 around, the cover body 30 is located above the mounting platform 20 and is fixedly connected with the mounting platform 20, an installation cavity S is formed between the cover body 30 and the mounting platform 20, and the installation cavity S is used for installing an antenna device 50. The outer contour of the cover body 30 is smoothly connected with the contour of the roof plate 10.

[0032] After the above arrangement, the antenna device 50 is installed in a relatively closed cavity through the arrangement of the cover body 30 and the mounting platform 20, so that the antenna device can be protected. Meanwhile, the outer contour of the cover body 30 is smoothly connected with the contour of the roof plate 10, so that the roof is more smooth, which is conducive to reducing the aerodynamic resistance and improving the aerodynamic performance of the rail vehicle.

[0033] Figure 1 The antenna device 50 is only a simple schematic and does not represent the actual structure. The specific structural composition and connection of the antenna device 50 can be realized based on the prior art, and are not the core of the application. Therefore, the details are not described here.

[0034] For example, in the width direction of the vehicle body, as shown in the left-right direction of the view angle, Figure 1 the mounting platform 20 and the cover body 30 are located in the middle region, and the roof plate 10 is located on both sides and has a curve structure protruding upward. At this time, the cross section of the cover body 30 also has a curve structure protruding upward, which is smoothly connected with the butt joint of the roof plate 10 on both sides. In this way, the outer contour of the cover body 30 is smoothly connected with the contour of the roof plate 10, which can improve the aerodynamic performance.

[0035] In other embodiments, the outer contour shape of the cover body 30 can be matched with the outer shape of the roof plate 10, and the smooth transition is tried to be achieved to avoid the protruding structure, so as to ensure the aerodynamic performance of the vehicle.

[0036] It should be understood that the roof plate 10 has a gap corresponding to the installation position at the position where the antenna device 50 needs to be installed. The gap is provided with the matching structure of the mounting platform 20 and the cover body 30, so that the mounting platform 20 and the cover body 30 together serve as part of the roof device. The size of the gap is related to the antenna device 50 to be installed.

[0037] Please refer to Figure 2 , Figure 2 for Figure 1 the enlarged view of the A position.

[0038] In this embodiment, along the vehicle width direction, both sides of the mounting platform 20 are provided with sunken step portions 21, i.e. the upper surfaces of the step portions 21 are lower than the upper surface of the main body of the mounting platform 20, the step portions 21 are provided with sliding grooves 211 extending along the vehicle length direction, the sliding grooves 211 are provided with fasteners 40, the heads of the fasteners 40 are in height direction limiting connection with the sliding grooves 211, the shank portions of the fasteners 40 are connected with the cover body 30, it can be understood that the heads of the fasteners 40 are located in the sliding grooves 211 and can slide along the sliding grooves 211, the shank portions of the fasteners 40 pass through the sliding grooves 211 upward, i.e. the fasteners 40 are arranged in an inverted manner, facilitating the connection of the mounting platform 20 and the cover body 30.

[0039] Specifically, the fasteners 40 can be a bolt and nut combination structure, the bolt is arranged in the sliding groove 211, the head of the bolt is located in the sliding groove 211, and the shank portion passes through the mounting hole of the cover body 30 and is fixed by the nut.

[0040] The above-mentioned connection mode of the mounting platform 20 and the cover body 30 is simple and reliable, the operation space is located above the cover body 30, i.e. outside the cover body 30, which is convenient to realize.

[0041] In the mounting platform 20 provided with the aforementioned sunken step portions 21, the fasteners 40 connecting the cover body 30 can be located in the sunken space of the step portions 21, which is beneficial to the smooth transition of the outer contour of the cover body 30 and the roof panel 10, and can avoid the connection structure of the cover body 30 and the mounting platform 20 protruding from the roof surface, which is beneficial to reducing the aerodynamic resistance of the vehicle.

[0042] At the same time, the structure design of the sunken step portions 21 of the mounting platform 20 is also beneficial to the drainage of the mounting platform 20.

[0043] In specific applications, the mounting platform 20 and the roof panel 10 can both adopt a profile structure, and the two can be fixed by welding, which is beneficial to ensuring the structural strength.

[0044] In actual application, a certain height range of the antenna device 50 needs to be a non-metallic area, therefore, in order to avoid affecting the normal work of the antenna device 50, the cover body 30 can be made of non-metallic materials such as glass steel or carbon fiber composite materials.

[0045] Please refer to Figure 3 , Figure 3 for Figure 1 the local enlarged view of the B part.

[0046] In the embodiment, the cover body 30 comprises a cover body 301 and a cover plate 302, wherein the cover body 301 has an opening hole 311 corresponding to the position of the antenna 51 of the antenna device 50, and the cover plate 302 is connected to the cover body 301 and is used to block the opening hole 311, and the cover plate 302 is a transparent cover plate. That is, the area of the cover body 30 corresponding to the antenna 51 is provided as a transparent structure. In this way, the reception of signals by the antenna 51 is facilitated, and the state of the antenna 51 is also convenient to view.

[0047] For example, the opening hole 311 of the cover body 301 is provided with a slot 312 having an opening facing the center of the opening hole 311, and the peripheral wall of the cover plate 302 has a plug-in part 321 capable of being plugged into the slot 312. In this way, the cover plate 302 and the cover body 301 are matched by plug-in, and the installation reliability is high.

[0048] In a specific arrangement, the cover plate 302 is flush with the upper surface of the cover body 301, and the thickness of the plug-in part 321 of the cover plate 302 can be less than the thickness of the main body of the cover plate 302. In this way, a stepped structure is formed between the plug-in part 321 and the main body of the cover plate 302, which can limit the extent of the plug-in part 321 inserted into the slot 312, so as to ensure the reliability of the connection between the cover plate 302 and the cover body 301.

[0049] In addition to the above-mentioned plug-in connection mode, the cover body 301 and the cover plate 302 can also be connected by means of glue or screws and other fasteners.

[0050] In a specific arrangement, along the vehicle width direction, the cover plate 302 is located in the middle region of the cover body 30, that is, the antenna 51 of the antenna device 50 is arranged in the middle region of the mounting cavity S and is arranged close to the center of the vehicle body. In combination with the fact that the mounting platform 20 is arranged in the middle region of the vehicle roof, the antenna 51 is arranged in the middle region of the vehicle roof, which is convenient for the antenna 51 to receive signals. Figure 1 As can be seen, in the middle region of the vehicle roof, the vertical distance between the cover body 30 and the mounting platform 20 is relatively large, which is convenient for the arrangement of the antenna device 50, and the cover body 30 is relatively flat in the middle region, which is conducive to the reception of signals by the antenna 51.

[0051] In the embodiment, as shown in Figure 1 and Figure 3 , a reinforcing rib 32 protruding downward is arranged on the inner surface of the cover body 30, that is, the surface facing the mounting platform 20. The reinforcing rib 32 can extend along the vehicle length direction and is provided with a plurality of reinforcing ribs 32 along the vehicle width direction. The arrangement of the reinforcing rib 32 can improve the structural strength and rigidity of the cover body 30.

[0052] The specific number and structure of the reinforcing rib 32 are not limited and can be arranged according to application needs.

[0053] For reference, Figures 4 to 6 , Figure 4A longitudinal sectional view of a roof device provided in an embodiment of the present application is shown in the figure; Figure 5 For Figure 4 A local enlarged view of a part C is shown in the figure; Figure 6 For Figure 4 A local enlarged view of a part D is shown in the figure.

[0054] In the embodiment, both ends of the mounting platform 20 are provided with mounting beams 22 along the vehicle length direction, the mounting beams 22 are fixedly connected with the roof panel 10, and the mounting beams 22 are connected with the cover body 30.

[0055] When specifically arranged, the mounting beam 22 can have an L-shaped structure, the horizontal beam segment of which is connected with the mounting platform 20, and the vertical beam end of which is connected with the roof panel 10, so that the mounting platform 20 can be arranged lower than the roof panel 10, which is beneficial to forming a mounting cavity S with a larger space between the mounting platform 20 and the cover body 30, and facilitates the installation of the antenna device 50.

[0056] The mounting beam 22 can be provided with a lapping surface portion which is lapped and matched with the roof panel 10, and the lapped portion can be fixed by welding or gluing or other fixing methods; the mounting beam 22 and the mounting platform 20 can also be lapped and matched, and then fixed together by welding or gluing or other fixing methods.

[0057] The cover body 30 is provided with a first insertion strip 31 downwardly at the end portion close to the mounting beam 22, the first insertion strip 31 can be formed by downwardly bending the end wall of the cover body 30, the mounting beam 22 is provided with a first insertion slot 221, the slot opening of the first insertion slot 221 is upwardly, and the first insertion strip 31 of the cover body 30 can be inserted into the first insertion slot 221, so that the cover body 30 is connected with the mounting beam 22 by insertion, which is convenient and reliable.

[0058] In other embodiments, the cover body 30 and the mounting beam 22 can also be connected by other methods, such as fixedly connected by bolts or other fasteners.

[0059] For example, when the total length of the cover body 30 along the vehicle length direction is relatively long, in order to facilitate the processing and installation of the cover body 30, the cover body 30 can be arranged in a segmented structure, specifically, the cover body 30 includes two or more cover segments 30a, each cover segment 30a is arranged along the vehicle length direction, and adjacent two cover segments 30a can be connected by an insertion structure or connected by fasteners.

[0060] Figure 4 And Figure 6 The insertion structure connecting the cover segments 30a is shown in the figure, specifically, an upward second insertion slot 31a is arranged on one cover segment 30a, a downward second insertion strip 32a is arranged on the adjacent other cover segment 30a, and the two cover segments 30a are connected by inserting the second insertion strip 32a into the second insertion slot 31a.

[0061] The plug-in connection is convenient for dismounting the cover part 30a and improves the convenience of overhauling the antenna device 50. In addition, the plug-in connection simplifies the construction process, reduces the use of fasteners, ensures the smoothness of the connection part, and improves the aerodynamic performance of the vehicle.

[0062] As shown in Figure 4 the figure, the two ends of the cover body 30 are inclined downward along the vehicle length direction, and the middle part of the cover body 30 is parallel to the vehicle length direction. In this way, the smooth transition between the cover body 30 and the roof plate 10 can be ensured, which is conducive to reducing the aerodynamic resistance and improving the aerodynamic performance of the railway vehicle.
