In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0049] In the description of the embodiments of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific situations.

[0050] In the embodiments of the present invention, unless otherwise clearly specified and limited, the first feature being "above" or "below" the second feature can be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature being "above", "above", and "on" the second feature can be that the first feature is directly above or obliquely above the second feature, or simply means that the first feature has a higher horizontal height than the second feature. The first feature being "below", "below", and "under" the second feature can be that the first feature is directly below or obliquely below the second feature, or simply means that the first feature has a lower horizontal height than the second feature.

[0051] In the description of this specification, the descriptions referring to terms such as "one embodiment", "some embodiments", "example", "specific example", or "some examples" mean that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the embodiments of the present invention. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. In addition, without contradiction, those skilled in the art can combine and combine the different embodiments or examples described in this specification and the features of different embodiments or examples.

[0052] The following will describe the embodiments of the present invention in conjunction with Figures 1 - 11 As shown, an end wall of a rail vehicle is provided in this embodiment, which mainly includes a first skeleton layer 10 and a second skeleton layer 20. Among them, the first skeleton layer 10 and the second skeleton layer 20 are mainly connected by argon arc welding, and the welding deformation generated by the argon arc welding can be absorbed by the first skeleton layer 10 and the second skeleton layer 20, so that the outer plate 110 has small deformation, the flatness of the outer plate 110 is improved, and the overall aesthetics of the end wall of the rail vehicle is improved. At the same time, in the forming stage, the first skeleton layer 10 and the second skeleton layer 20 can be mass-produced separately first, and then the first skeleton layer 10 and the second skeleton layer 20 are welded in batches, reducing the construction difficulty, realizing batch construction, and saving labor and time.

[0053] As Figure 3 shown, the first skeleton layer 10 includes an outer plate 110 and a beam structure, and the beam structure is connected to the outer plate 110. The second skeleton layer 20 is connected to the side of the beam structure facing away from the outer plate 110. It can be understood that when the first skeleton layer 10 and the second skeleton layer 20 are welded, the outer plate 110 of the first skeleton layer 10 and the second skeleton layer 20 are mainly connected by the beam structure in an over-connected manner, and will not directly act on the outer plate 110 during welding. The welding deformation generated during the welding process can be absorbed by the beam structure and the second skeleton layer 20, so that the outer plate 110 has small deformation, the flatness of the outer plate 110 is improved, and the overall aesthetics of the end wall of the rail vehicle is improved.

[0054] As Figure 4 and Figure 5As shown, the beam structure includes a first beam structure arranged along the direction of the upper crossbeam 230 of the door and a second beam structure arranged along the direction of the door post 220, and the first beam structure and the second beam structure are arranged in the windshield installation area for installing the outer windshield on the side of the outer panel 110 facing away from the beam structure. The windshield installation area is the area for installing the outer windshield on the side wall of the rail vehicle. The positions of the windshield installation areas corresponding to different outer windshields are generally the same, and the only difference is the difference in the installation points of different outer windshields. After setting the first beam structure and the second beam structure, the installation points can be adjusted to a certain extent in the width direction and the height direction, so as to adapt to different types of outer windshields. At the same time, after the outer windshield is fixed, the force is directly transmitted to the first beam structure and the second beam structure and will not act on the outer panel 110, which can meet the strength requirements.

[0055] In this embodiment, the end wall structure of the rail vehicle is formed by the first skeleton layer 10 and the second skeleton layer 20, which is convenient for the mass construction of the end wall of the rail vehicle, saving labor and time. During the welding and forming process, the first skeleton layer 10 and the second skeleton layer 20 can absorb the deformation generated by welding to a certain extent, making the deformation of the outer panel 110 smaller and having good aesthetics. The first beam structure and the second beam structure of the first skeleton layer 10 are arranged at the positions of the windshield installation area. When installing the windshield, the installation points of the windshield can be adjusted to a certain extent in the width direction and the height direction. Based on the adjustment of the installation points, it can adapt to different outer windshields and achieve the interchangeability of the end wall structure. It can also reduce the welding amount of the outer panel 110 and improve the flatness and aesthetics of the outer panel 110.

[0056] When fixing the outer windshield, a backing plate can also be provided on the outer side of the outer panel 110. The backing plate cooperates with the first beam structure and the second beam structure to fix the outer windshield, which not only ensures the strength of the installation position but also takes into account various windshields and realizes the interchangeability of the end wall structure. Among them, the outer side of the outer panel 110 refers to the side of the outer panel 110 facing away from the beam structure. Correspondingly, the inner side of the outer panel 110 refers to the side of the outer panel 110 facing the beam structure.

[0057] The outer windshield can be fixed to the outer panel 110, the first beam structure and the second beam structure by fasteners. The fixing method is relatively conventional and will not be elaborated here.

[0058] The end wall of the rail vehicle in this embodiment is particularly suitable for the end wall with a stainless steel plate beam structure. Among them, the outer panel 110 can be made of a 1.5-mm-thick stainless steel plate.

[0059] In this embodiment, the first beam structure and the second beam structure are suitable for being connected to the outer panel 110 by resistance spot welding. During the resistance spot welding process of the first beam structure and the outer panel 110 and the second beam structure and the outer panel 110, the welding heat input is small, making the deformation of the outer panel 110 smaller and further improving the flatness and aesthetics of the outer panel 110.

[0060] According to the end wall of the rail vehicle provided by the present invention, the first beam structure includes at least two first hat-shaped beams 120 arranged at intervals in the height direction of the rail vehicle. The first hat-shaped beam 120 includes a first beam body 1210 and first bending portions 1220 formed by bending outwardly on both sides of the first beam body 1210. Among them, at least one first hat-shaped beam 120 is adapted to be connected to the outer plate 110 through the first beam body 1210, and the remaining first hat-shaped beams 120 are adapted to be connected to the outer plate 110 through the first bending portions 1220.

[0061] As Figure 4 shown, the first hat-shaped beam 120 connected to the outer plate 110 through the first bending portion 1220 can form a positive hat-shaped structure, and the first hat-shaped beam 120 connected to the outer plate 110 through the first beam body 1210 can form an inverted hat-shaped structure. The outer windshield is arranged on the outside of the outer plate 110 at the position of the first beam body 1210 of the inverted hat-shaped structure, so that the force on the outer windshield is directly transmitted to the first beam body 1210, ensuring the strength of the installation position, and enabling the installation points of the outer windshield to be adjusted to a certain extent in the width and height directions.

[0062] It can be understood that at least one first hat-shaped beam 120 is connected to the outer plate 110 through the first beam body 1210 by means of resistance spot welding, and the remaining first hat-shaped beams 120 are connected to the outer plate 110 through the first bending portions 1220 on both sides of the first beam body 1210 by means of resistance spot welding.

[0063] According to the end wall of the rail vehicle provided by the present invention, the second beam structure includes at least two second hat-shaped beams 130 arranged at intervals in the width direction of the rail vehicle. The second hat-shaped beam 130 includes a second beam body 1310 and second bending portions 1320 formed by bending outwardly on both sides of the second beam body 1310. Among them, at least one second hat-shaped beam 130 is adapted to be connected to the outer plate 110 through the second beam body 1310, and the remaining second hat-shaped beams 130 are adapted to be connected to the outer plate 110 through the second bending portions 1320.

[0064] As Figure 5 shown, the second hat-shaped beam 130 connected to the outer plate 110 through the second bending portion 1320 can form a positive hat-shaped structure, and the second hat-shaped beam 130 connected to the outer plate 110 through the second beam body 1310 can form an inverted hat-shaped structure. The outer windshield is arranged on the outside of the outer plate 110 at the position of the second beam body 1310 of the inverted hat-shaped structure, so that the force on the outer windshield is directly transmitted to the second beam body 1310, ensuring the strength of the installation position, and enabling the installation points of the outer windshield to be adjusted to a certain extent in the width and height directions.

[0065] It is understandable that at least one second hat-shaped beam 130 is connected to the outer plate 110 through the second beam body 1310 by means of resistance spot welding, and the remaining second hat-shaped beams 130 are connected to the outer plate 110 through the second bending portions 1320 on both sides of the second beam body 1310 by means of resistance spot welding.

[0066] According to the end wall of the rail vehicle provided by the present invention, the second skeleton layer 20 includes a pair of end corner columns 210, a pair of door columns 220, an upper cross beam 230 on the door, and a top bent beam 240. The pair of door columns 220 are arranged at intervals between the pair of end corner columns 210. The adjacent door columns 220 and end corner columns 210 are connected by a small cross beam 250. The upper cross beam 230 on the door is arranged between the pair of door columns 220. The two ends of the top bent beam 240 are respectively connected to the upper ends of the pair of end corner columns 210, and the top bent beam 240 is adapted to be connected to the upper cross beam 230 on the door through a vertical beam 260. Among them, at least one first hat-shaped beam 120 is adapted to the upper cross beam 230 on the door, and at least one second hat-shaped beam 130 is adapted to the end corner column 210.

[0067] As Figure 6 shown, an end door structure can be formed between the pair of door columns 220. The upper cross beam 230 on the door, the end corner column 210, the door column 220, and the top bent beam 240 serve as load-bearing structures, and the small cross beam 250 and the vertical beam 260 can also play the role of force transmission and load-bearing. Among them, at least one first hat-shaped beam 120 is adapted to the upper cross beam 230 on the door, and at least one second hat-shaped beam 130 is adapted to the end corner column 210, so as to strengthen the upper cross beam 230 on the door and the end corner column 210 by using the first hat-shaped beam 120 and the second hat-shaped beam 130, so as to improve the strength of the end wall of the rail vehicle and the strength of the whole vehicle.

[0068] The end corner column 210, the door column 220, the upper cross beam 230 on the door, the top bent beam 240, the small cross beam 250, and the vertical beam 260 are connected by means of resistance spot welding and / or argon arc welding.

[0069] As Figure 8 shown, the end corner column 210 includes a stepped beam body formed by multiple bends. The stepped beam body is connected to the small cross beam 250, the second hat-shaped beam 130, and the outer plate 110. Using a thick plate to form the end corner column 210 by multiple bends can improve the strength of the end corner column 210, so as to better play the role of support and load-bearing.

[0070] Specifically, the end corner column 210 includes a plurality of connected L-shaped beam bodies, and the plurality of L-shaped beam bodies are welded to form a stepped beam body, thereby forming the end corner column 210. Among them, the end corner column 210 is connected by an arc transition at the bending part.

[0071] As Figure 9As shown, the door post 220 includes an outer post 2210 and an inner post 2220. The outer post 2210 includes a first beam, a second beam spaced from the first side beam, a third beam disposed between the first beam and the second beam, and a fourth beam connected to the first beam. Among them, an opening is formed between the fourth beam and the second beam, and the second beam bends away from the opening direction to form a connecting beam. The inner post 2220 is in a C shape, the inner post 2220 is disposed inside the outer post 2210, and the opening of the inner post 2220 faces the second beam. Among them, the second beam and the connecting beam are adapted to be connected to the small cross beam 250, and the third beam is adapted to be connected to the vertical plate.

[0072] The door post 220 adopts a double-layer post structure, making the door post 220 have relatively high strength. The first beam, the second beam, the third beam and the fourth beam of the outer post 2210 enclose a frame structure with an opening. Among them, the joints of the first beam, the second beam, the third beam and the fourth beam are connected by an arc transition. The second beam extends outward to form a connecting beam to connect the small cross beam 250, realizing the connection between the first skeleton layer 10 and the second skeleton layer 20.

[0073] The C-shaped inner post 2220 can play a good supporting and strengthening effect inside the outer post 2210, improving the overall strength of the door post 220.

[0074] In this embodiment, the inner post 2220 includes a bottom edge, a side edge and a top edge connected in sequence. The bottom edge is flush with one end of the fourth beam close to the opening, and the top edge extends to the joint of the second beam and the third beam. This enables the inner post 2220 to better fit inside the outer post 2210, strengthening the structure without affecting the aesthetics of the door post 220.

[0075] As Figure 7 shown, the upper door beam 230 is in a C shape. One end of the upper door beam 230 bends towards the opening direction of the upper door beam 230 to form a first strengthening beam 2310, and the other end of the upper door beam 230 bends away from the opening direction of the upper door beam 230 to form a second strengthening beam 2320. The upper door beam 230 also improves its strength through multiple bends. Among them, the upper door beam 230 can be welded to the first hat-shaped beam 120, and the first hat-shaped beam 120 can further strengthen the strength of the upper door beam 230.

[0076] On the other hand, the present invention also provides a rail vehicle, including a vehicle body and the rail vehicle end wall in the foregoing embodiment. The vehicle body includes multiple connected carriages, and the rail vehicle end wall is installed at both ends of each carriage.

[0077] In this embodiment, by installing the above-mentioned end wall of the rail vehicle at both ends of the vehicle body and using the first skeleton layer 10 and the second skeleton layer 20 to form the end wall structure of the rail vehicle, it is convenient for the mass production of the end wall of the rail vehicle, saving labor and time. During the welding and forming process, the first skeleton layer 10 and the second skeleton layer 20 can absorb the deformation generated by welding to a certain extent, resulting in less deformation of the outer plate 110 and good aesthetics. The first beam structure and the second beam structure of the first skeleton layer 10 are arranged at the position of the windshield installation area. When installing the windshield, the installation points of the windshield can be adjusted to a certain extent in the width direction and the height direction. Based on the adjustment of the installation points, it can adapt to different external windshields and achieve the interchangeability of the end wall structure.

[0078] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
