Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0052] The locomotive generally comprises a plurality of vehicle cabins, and the vehicle cabin is provided with an end wall 100 at each end, which blocks the two ends of the vehicle cabin, so that the vehicle cabin forms a closed box. As shown in Figs. 1 to 5, the end wall 100 according to an embodiment of the present application comprises an upper profile plate assembly 1, two end wall side plate assemblies 2 and two end upright columns 4. The two end wall side plate assemblies 2 are arranged at intervals, and the top of each end wall side plate assembly 2 is connected to the upper profile plate assembly 1. The upper profile plate assembly 1 and the two end wall side plate assemblies 2 jointly form an aisle 3, which communicates between adjacent vehicle cabins, facilitating the passage of passengers.

[0053] The end wall 100 of the present application is formed with the accommodating cavity 22, which extends along the longitudinal direction of the vehicle body, increases the longitudinal space inside the vehicle, and provides installation space for structural members such as tools and cables. The end wall 100 of the present application has a simple structure and a reasonable design, and is suitable for promotion.

[0054] In some possible implementation, referring to FIG. 1 to FIG. 3, the end wall side plate assembly 2 has two first spliced plates 21, each of which has a main plate 211 and a convex shell 212 connected to the main plate 211, the main plates 211 of the two first spliced plates 21 are located in the same plane, and the convex shells 212 of the two first spliced plates 21 are spliced to form a box structure having a receiving cavity 22. The convex shell 212 on the first spliced plate 21 can be directly extruded from a profile, and the two first spliced plates 21 are fixed by welding so that the two convex shells 212 are connected to form the box structure. Instead of directly stamping the receiving cavity 22 on one plate body 111, the end wall side plate assembly 2 provides two first spliced plates 21, the convex shell 212 is stamped at the edge position of each spliced plate, and the receiving cavity 22 is formed by splicing the convex shells 212 on the two spliced plates, thereby improving the yield of stamping, simplifying the process difficulty, and improving the production efficiency.

[0055] In some possible implementation, referring to FIG. 3, the convex shell 212 includes a shell plate 2121 and a connecting plate 2122, the shell plate 2121 is spaced apart from the main plate 211, and the connecting plate 2122 connects the main plate 211 and the shell plate 2121, respectively, and the thickness end faces of the shell plates 2121 of the two first spliced plates 21 abut.

[0056] In this embodiment, the shell plate 2121 is substantially parallel to the main plate 211, the spacing between the shell plate 2121 and the main plate 211 is the longitudinal dimension of the receiving cavity 22, and the connecting plate 2122 connects the shell plate 2121 and the main plate 211. When the two first spliced plates 21 are spliced, the thickness end faces of the convex shells 212 of the two first spliced plates 21 abut, and the two convex shells 212 are fixed by welding.

[0058] The two sides of the second spliced plate 23 in the width direction are welded and fixed with the corresponding first spliced plate 21, respectively, and the upper edge of the top second spliced plate 23 can be welded and fixed with the upper profile plate assembly 1. The second spliced plate 23 connects the two first spliced plates 21. The two second spliced plates 23 avoid the receiving cavity 22, and the two second spliced plates 23 and the main plates 211 of the two first spliced plates 21 enclose an opening of the receiving cavity 22.

[0059] In some possible embodiments, referring to FIG. 3, the end wall side plate assembly 2 includes a patch 24, a through hole is formed between the second splice plate 23 and the shell plate 2121 to communicate with the accommodating cavity 22, and the patch 24 is used to fill the through hole. Specifically, the patch 24 is substantially perpendicular to the second splice plate 23, the patch 24 is connected to the second splice plate 23 and the shell plate respectively, and the patch 24 closes the through hole, so that the accommodating cavity 22 is formed between the first splice plate 21 and the second splice plate 23 without any leakage.

[0060] In some possible embodiments, referring to FIG. 1 and FIG. 4, the upper profile plate assembly 1 includes an upper profile plate 11 and an arc-shaped sealing plate 12, the upper profile plate 11 is connected to two end wall side plate assemblies 2, and the arc-shaped sealing plate 12 is arranged on a side of the upper profile plate 11 away from the end wall side plate assembly 2. The arc-shaped sealing plate is connected to the corresponding end upright column 4 on both sides.

[0061] The top of the end wall 100 of the vehicle body usually has more profile bending pieces, which are difficult to bend and have high production cost. In the embodiment of the present application, the plurality of profile bending pieces in the original scheme are cancelled, and the arc-shaped sealing plate 12 is used instead. The upper profile plate 11 of the upper profile plate assembly 1 is not a bending piece, and the arc-shaped sealing plate 12 is a flat plate body 111 instead of a bent aluminum profile. For example, the arc-shaped sealing plate 12 is a flat solid aluminum plate, and the arc-shaped sealing plate 12 can be a 12mm thick aluminum plate. The structural design of the upper profile plate assembly 1 of the present application reduces the number of end wall bending pieces, thereby changing the connection mode of the roof 220, the side wall 210 and the end wall 100 of the vehicle body, and more conducive to the direct transmission of the end longitudinal force.

The provision of the transition bending beam piece 13 realizes the connection of the arc-shaped sealing plate 12 and the upper profile plate 11. The profile connecting strip 131 with a greater thickness is arranged on the concave side of the arc-shaped sealing plate 12, which facilitates the connection of the arc-shaped sealing plate 12 and the upper profile plate 11. The plate body connecting strip 132 with a smaller thickness is arranged on the convex side of the arc-shaped sealing plate 12, which thickness matches that of the arc-shaped sealing plate 12, and facilitates the welding and fixation of the arc-shaped sealing plate 12.

[0063] In some possible solutions, the profile connecting strip 131 comprises two side strips 1311 arranged at intervals and an end strip 1312 connecting the two side strips 1311, and the plate body connecting strip 132 is connected to the end strip 1312.

The arc-shaped sealing plate 12 is divided into two arc-shaped plate members 121, which can reduce the size of the workpiece and facilitate production.

[0065] The profile wall thickness of the car body end wall 100 can be reduced to 40 mm, and the inner rib wall thickness is adjusted, so as to achieve the purpose of reducing the weight of the end wall. The end wall structure of the present application is designed with the idea of light weight, and is designed on the basis of sufficient strength and rigidity, which reduces the cost of the car body end wall 100 and improves the production efficiency of the car body end wall 100. The car body end wall 100 has few components, few welds, reduces the number of bending profiles, and reduces the production cost of the product. The car body end wall 100 has good structural stability and is not easy to deform. The car body end wall 100 structure of the present application can not only meet the light weight design requirement, but also meet the strength and rigidity requirement, and maximizes the effective space inside the car.

[0069] In the embodiments of the present application, the cross-sectional dimension of the end upright column 4 is increased, the door column on the side wall 210 is cancelled, and the number of welds is reduced. The end upright column 4 in an integral structure is beneficial to increase the strength of the end structure and improve the problem caused by the stress concentration of the open end.
