In order to improve the load bearing capacity of the end wall 200, according to a first aspect of the embodiment of the present application, fig. 12 is a schematic perspective view of the crash column structure 100 provided by the embodiment of the present application, fig. 13 is a schematic side view of a first viewing angle of the crash column structure 100 provided by the embodiment of the present application, and fig. 16 is a schematic sectional view along line B-B in fig. 13, as shown in fig. 12, 13 and 16, the embodiment of the present application provides an end wall 200 of a railway passenger car, the end wall 200 includes the crash column structure 100, and the crash column structure 100 includes a column main body 1 and an inner rib plate 30. The column body 1 is a hollow tubular structure. The column body 1 includes a column body 10 and a closing plate 20. The column 10 includes a first side wall 11, a second side wall 12, and a third side wall 13 configured in a U-shaped configuration. The first side wall 11 and the second side wall 12 are arranged oppositely and at intervals along the thickness direction of the end wall, and the third side wall 13 is connected between the first side wall 11 and the second side wall 12, so that the column main body 1 with a U-shaped structure is formed together. The closing plate 20 is disposed opposite to the third side wall 13, and the closing plate 20 covers the opening between the first side wall 11 and the second side wall 12. The inner rib 30 extends upwards from the bottom of the column body 1 along the length direction of the column body 1, and two sides of the inner rib 30 along the width direction are respectively connected with the first side wall 11 and the second side wall 12. To explain that the end wall 200 is in a normal use state, the length direction of the inner rib plate 30 is the height direction of the vehicle body, the thickness direction of the inner rib plate 30 is the transverse direction of the vehicle body, and the width direction of the inner rib plate 30 is the longitudinal direction of the vehicle body.

Alternatively, the column body 10 may be a U-shaped structure, and the inner rib 30 may be a steel plate welded to the main body, thereby collectively forming the column main body 1 having a rectangular cross section.

When the headwall 200 of the railway passenger car is impacted by another railway passenger car, the impact position is located at the bottom of the crash column structure 100, wherein, because the first side wall 11 and the second side wall 12 are arranged at intervals along the longitudinal direction of the car body, one of the first side wall 11 and the second side wall 12 faces the inside of the car compartment, the other one faces the outside of the car compartment, and the bottom of the second side wall 12 is the position of the crash column structure 100 which is firstly contacted with the impact object (such as the head of the other railway passenger car). For convenience of description, the first side wall 11 is directed toward the vehicle interior, and the second side wall 12 is directed toward the vehicle exterior.

In the application, through the inside at the bottom of post main part 1 sets up interior gusset 30, as shown in fig. 16, post main part 1 and interior gusset 30 form the cross section of "bow" font jointly, can improve the intensity of post main part 1 bottom, the elastoplasticity of post main part 1 is better, improve its resistance to compression bearing capacity, to the impact position-the bottom of preventing bumping post structure 100, carry out local enhancement, when receiving the striking, the position that this atress is the biggest warp and has reduced, thereby can not cause the production too big deformation in other positions that link to each other, consequently, can improve the resistance to compression bearing capacity of whole anticollision post structure 100, furthest satisfies the collision demand of headwall 200. Only the most stressed part is locally reinforced, and the weight of the end wall 200 is not increased excessively. Further, since the width direction of the inner gusset 30 is extended in the vehicle body longitudinal direction, in other words, the width direction of the inner gusset 30 is extended in the collision direction. When receiving the striking, compare for the mode along vehicle body transverse arrangement inner rib plate 30, the inner rib plate 30 that this application adopted arranges the mode and is more difficult to take place to warp, and the resistance to compression bearing capacity is stronger to make the holistic resistance to compression bearing capacity of bumping post structure 100 stronger.

In addition, since the column main body 1 is composed of the U-shaped column 10 and the closing plate 20, when fixing the inner rib plate 30, the closing plate 20 may not be fixed, the inner rib plate 30 is fixed into the U-shaped cavity of the U-shaped column 10, and then the closing plate 20 is covered on the column 10, for example, the closing plate 20 is fixed by welding. When the inner rib plate 30 is fixed by welding, the column body 1 composed of the U-shaped column body 10 and the closing plate 20 can improve the welding workability of the inner rib plate 30.

Because interior gusset 30 runs through post main part 1 completely to inlay and establish in first lateral wall 11 and second lateral wall 12, when receiving the collision, interior gusset 30 can contact with the collision object the very first time, bears the impact with the lateral wall of post main part 1 jointly, thereby can reduce the deformation of post main part 1 lateral wall, improves the holistic resistance to compression bearing capacity of crashproof post structure 100. Moreover, the arrangement of the first groove 111 and the second groove 121 can limit the displacement of the inner rib plate 30 in the column body 1, and can also facilitate the insertion of the inner rib plate 30 into the column body 1 from the first groove 111 or the second groove 121.

Because the inner rib plate 30 is arranged in the middle of the column main body 1, when the column main body is impacted, force can be uniformly transmitted to the side walls at two sides, so that the side walls of the column main body 1 at two sides of the inner rib plate 30 can uniformly resist the impact, and the phenomenon that the deformation is overlarge due to insufficient local strength is prevented. Optionally, the bottom of the inner rib plate 30 has a rectangular structure.
