[0054] Embodiment one

[0055] Referring to Figures 1 to 7 As shown in the drawings, the present application provides a roof structure with windows for rail train, which comprises a roof plate assembly 1 and a side plate assembly 2. The roof plate assembly 1 extends along the length direction of the rail train. The side plate assembly is arranged on both sides of the roof plate assembly 1 along the width direction of the rail train, and the side plate assembly 2 is inclinedly connected to the roof plate assembly 1, and the two side plate assemblies 2 are away from each other on the side away from the roof plate assembly. Wherein, the side plate assembly 2 comprises a first corner beam 21, a second corner beam 22 and a plurality of single pieces 23, the first corner beam 21 is connected to the roof plate assembly 1, the second corner beam 22 is arranged at intervals with the first corner beam 21, each single piece 23 is arranged between the first corner beam 21 and the second corner beam 22, the single pieces 23 are arranged at intervals along the length direction of the rail train in sequence, and the single pieces 23 are connected to the first corner beam 21 and the second corner beam 22 respectively, and the window a is formed between the adjacent two single pieces 23. The novel roof structure with windows for rail train of the present application forms the window a between the adjacent two single pieces 23 of the side plate assembly 2, the window a is arranged on the side plate assembly 2, the sunlight time is longer, the lighting property is better, the brightness in the car is higher, the quality of the roof structure is lighter, and the sightseeing property and energy saving property of the rail train are effectively improved. Moreover, the roof structure is high in modularization, small in welding amount during assembly, convenient in welding operation, and high in overall structural strength.

[0056] At least part of the monolithic piece 23 has different extension sizes in the direction of the length of the rail vehicle. According to the structural features of the rail vehicle body and the strength requirements of each structure of the rail vehicle body, the monolithic piece 23 at the position where the structural strength is required to be large is set to have a long extension size in the direction of the length of the rail vehicle, so as to ensure the structural strength, for example, the monolithic piece 23 arranged at both sides of the rail vehicle body has a long extension size in the direction of the length of the rail vehicle. The monolithic piece 23 at the position where the structural strength is required to be small is set to have a small extension size in the direction of the length of the rail vehicle.

[0057] In a possible implementation, as shown in Figure 1 and Figure 2 each monolithic piece 23 comprises a plurality of columns 231 and a plurality of plates 232, each column 231 and each plate 232 are arranged in sequence and spaced apart in the direction of the length of the rail vehicle, and the window a is formed between two adjacent columns 231 and plates 232. The plate 232 has a long length, that is, a long extension size in the direction of the length of the rail vehicle, and has high structural strength, which is suitable for being arranged at the position where the weight force is large, for example, both sides of the roof of the rail vehicle. The column 231 has a small extension size in the direction of the length of the rail vehicle.

[0058] As shown in Figure 1 and Figure 2 each plate 232 comprises a first plate 2321 and a second plate 2322, the first plate 2321 and the second plate 2322 are arranged at both ends of the first corner beam 21, and each column 231 is arranged between the first plate 2321 and the second plate 2322. The end structure of the first corner beam 21 has a large weight force and is easy to deform, and has a high structural strength requirement, and the first plate 2321 and the second plate 2322 are arranged at both ends of the first corner beam 21, respectively, and the plate 232 has high structural strength, so that the end structure of the first corner beam 21 has high structural strength.

[0059] As shown in Figure 1 and Figure 2 the plate 232 comprises a third plate 2323. The third plate 2323 is located between the first plate 2321 and the second plate 2322, and the third plate 2323 is located at the top of the door opening of the rail vehicle. The position of the door opening is empty, and the structural strength of the door opening itself is weak, so the top of the door opening needs to have higher structural strength, and the third plate 2323 is arranged at the top of the door opening to strengthen the structural strength of the top of the door opening, so that the structural strength of the door meets the requirements.

[0060] Along the length of the train, the extension dimension of the third plate 2323 is greater than that of the first plate 2321 and the second plate 2322. Because the door opening is wide, the structural strength required at the door opening is greater, and the extension dimension of the third plate 2323 needs to be long enough to strengthen the structure.

[0061] In one possible implementation, at least one column 231 is disposed between the third plate 2323 and the first plate 2321. At least one column 231 is also disposed between the third plate 2323 and the second plate 2322. The relatively long distances between the third plate 2323 and the first plate 2321, and between the third plate 2323 and the second plate 2322, result in lower structural strength. By distributing at least one column 231 between the third plate 2323 and the first plate 2321, and between the third plate 2323 and the second plate 2322, the structural strength is increased. The column 231 is short along the length of the vehicle body, and its slender structure does not obstruct the natural light entering the vehicle interior, while also providing better structural reinforcement, thus increasing structural strength.

[0062] like Figure 1 and Figure 2 As shown, the first corner beam 21 includes a first beam body 211 and a second beam body 212. The first beam body 211 is connected to the roof assembly 1, and the second beam body 212 and the first beam body 211 have an included angle. Each of the individual components 23 is connected to the second beam body 212. The first beam body 211 and the roof assembly 1 are substantially in the same plane. The side end faces of the first beam body 211 and the roof assembly 1 are welded together. The second beam body 212 has an arc surface that curves downward toward both sides of the vehicle body in the direction along the width of the vehicle body. The upper end face of the second beam body 212 is welded to the lower end face of the first beam body 211, and the lower end face of the second beam body 212 is connected to each of the individual components 23.

[0063] like Figure 3 and Figure 4As shown, the roof assembly 1 has a first upper layer plate 1a and a first lower layer plate 1b, and the first upper layer plate 1a extends out of the first lower layer plate 1b along the vehicle width direction of the rail train. The first beam body 211 has a second upper layer plate 2111 and a second lower layer plate 2112, and the second lower layer plate 2112 extends out of the second upper layer plate 2111 along the vehicle width direction of the rail train. A connecting rib b is arranged between the first upper layer plate 1a and the first lower layer plate 1b and between the second upper layer plate 2111 and the second lower layer plate 2112, so that the middle part of the roof assembly 1 and the first beam body 211 is a hollow structure, which is in line with the mechanical principle, so that the weight of the roof structure is greatly reduced, the use of materials is less, and the structural strength meets the requirements. The first upper layer plate 1a is attached to the upper surface of the second upper layer plate 2111, and the first upper layer plate 1a and the second upper layer plate 2111 are welded and fixed at the attached part. The first lower layer plate 1b is attached to the upper surface of the second lower layer plate 2112, and the first lower layer plate 1b and the second lower layer plate 2112 are welded and fixed at the attached part. The matching structure facilitates the attachment before welding during assembly.

[0064] In one possible implementation, as shown in Figure 3 and Figure 6 As shown, the first plate body 2321 is provided with a matching beam 2321a attached to the first plate body 2321, and one end of the matching beam 2321a extends out of the first side plate to the side of the first corner beam 21. The extended part of the matching beam 2321a is attached to the outer surface of the first corner beam 21, and the end of the first plate body 2321 close to the first corner beam 21 abuts against the lower end surface of the first corner beam 21. The attached structure facilitates welding connection.

[0065] As shown in Figure 1 and Figure 7 As shown, the first corner beam 21 is provided with a first glass mounting step 213 on the side facing the second corner beam 22, and the second corner beam 22 is provided with a second glass mounting step 221 on the side facing the first corner beam 21. The two ends of each single piece 23 are attached to the first glass mounting step 213 and the second glass mounting step 221 respectively, and the single piece 23 is provided with a lap step c on the side close to the window a. The first glass mounting step 213, the second glass mounting step 221 and the lap step c are located in the same plane. The glass is attached to the first glass mounting step 213, the second glass mounting step 221 and the lap step c of the adjacent two single pieces 23. It is convenient to attach and install the four edges of the glass respectively.

[0066] In a possible implementation form, as shown in Figure 1 and Figure 2 The top plate assembly 1 includes a top middle plate 11 and two top side plates 12, which are arranged on both sides of the top middle plate 11 and connected to the top middle plate 11, and the first corner beam 21 of the side plate assembly 2 is connected to one side of the corresponding top side plate 12 away from the top middle plate 11. The top plate assembly 1 is modularly arranged, so that the structure of the top plate assembly 1 is smaller, facilitating transportation and installation of materials.

[0067] The novel top structure of the rail train with windows of the application is welded by seven top plate processing modules of two first plate bodies 2321, two second plate bodies 2322, two third plate bodies 2323, a top plate assembly 1 and a side plate assembly 2, each module is independent of each other, easy to manufacture, maintain, and has high dimensional accuracy, and forms a whole module of the top structure after welding.

[0068] Example two

[0069] The application also provides a rail train with the above-mentioned top structure of the rail train with windows. The top structure is one of the main load-bearing parts of the car body, provides a passenger space, and has a side wall at the lower side, a bottom frame at the bottom, and an end wall and a driver's room at both ends. The two second corner beams 22 of the top structure of the rail train with windows are connected to the two side walls respectively to close the upper opening of the car body. The profile of the top structure can be preferably made of EN AW-6005A-T6 material, which has light weight and high structural strength, so that the mass of the rail train of the application is lighter.

[0070] According to the use requirements of other positions of the rail train and the structural design requirements of air conditioners, receivers and windows, eight different sectional profiles of the novel top structure of the rail train with windows of the application are designed to ensure the structural strength of each sectional profile. The sectional material of the top structure is integrally formed by extrusion structure, and the wall thickness adopts a structure form with different thicknesses of 3-8 mm. The internal rib plate of each profile is arranged according to the requirements, which conforms to the mechanical principle, maximizes the use requirements of the internal rib plate at the interface under the premise of ensuring the structural strength, and at the same time, the weight of the car body is reduced as much as possible.

[0071] The novel top structure of the rail train with windows of the application adopts a process production mode of different profile butt welding, and the process production flow can be: profile processing-module welding-module whole processing-profile and module assembly welding-attachment interface welding, finally forming a whole module of the top structure.

[0072] In order to meet the structure bearing function, the connection between the profiles used by the roof structure and between the roof structure and other vehicle body parts can all adopt the butt welding through welding process with a pad, which has simple welding structure, good welding process, small deformation, strong operability and high strength.

[0073] The above description is only the preferred embodiment of the present application, and does not limit the present application in any form. Although the present application has been disclosed as above with the preferred embodiment, it is not intended to limit the present application. Any skilled person in the art can make some changes or modifications to the above-mentioned technical content without departing from the technical solution of the present application, and any simple modification, equivalent change and modification of the above-mentioned embodiments made according to the technical essence of the present application still belong to the scope of the present application.
