The column body 1 is of 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 structure. The first side wall 11 and the second side wall 12 are disposed opposite to and spaced apart from each other in 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, thereby forming the column body 1 of the U-shaped structure together. The closing plate 20 is arranged 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 plate 30 extends upward from the bottom of the column body 1 along the length direction of the column body 1, and both sides of the inner rib plate 30 along the width direction are respectively connected with the first side wall 11 and the second side wall 12. The end wall 200 is described 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 10 may be of a U-shaped configuration and the inner web 30 may be steel plates welded to the body to collectively form a rectangular cross-section column body 1.
When the end wall 200 of the railway car is impacted by other railway cars, the impact part is located at the bottom of the collision post structure 100, wherein, since the first side wall 11 and the second side wall 12 are arranged along the longitudinal space of the car body, one of the first side wall 11 and the second side wall 12 faces the inside of the car, the other one faces the outside of the car, and the bottom of the second side wall 12 is the part of the collision post structure 100 which is firstly contacted with the collision object (such as the head of other railway cars). Hereinafter, for convenience of explanation, the first side wall 11 is directed toward the inside of the vehicle cabin, and the second side wall 12 is directed toward the outside of the vehicle cabin.
In the present application, by arranging the inner rib plate 30 inside the bottom of the column body 1, as shown in fig. 16, the column body 1 and the inner rib plate 30 are formed into an arc-shaped cross section, so that the strength of the bottom of the column body 1 can be improved, the elastoplasticity of the column body 1 is better, the compression bearing capacity of the column body is improved, the impact part, namely the bottom of the anti-collision column structure 100, is locally reinforced, and the deformation of the part with the largest stress is reduced when the column body is impacted, so that the excessive deformation of other connected parts is not caused, and therefore, the compression bearing capacity of the whole anti-collision column structure 100 can be improved, and the collision requirement of the end wall 200 is met to the greatest extent. Only the portion where the stress is greatest is locally reinforced, and the weight of the headwall 200 is not excessively increased. Further, since the width direction of the inner rib 30 is extended in the vehicle body longitudinal direction, in other words, the width direction of the inner rib 30 is extended in the striking direction. Compared with the mode of arranging the inner rib plates 30 transversely along the vehicle body, the mode of arranging the inner rib plates 30 is less prone to deformation and higher in compression resistance bearing capacity, so that the whole anti-collision column structure 100 is higher in compression resistance bearing capacity.
In addition, since the column body 1 is composed of the U-shaped column body 10 and the closing plate 20, when the inner rib plate 30 is fixed, the closing plate 20 is not fixed, the inner rib plate 30 is fixed in the U-shaped cavity of the U-shaped column body 10, and then the closing plate 20 is covered on the column body 10, for example, the closing plate 20 is fixed by welding. When the inner rib 30 is fixed by welding, the column body 1 composed of the U-shaped column 10 and the closing plate 20 can improve the welding workability of the inner rib 30.
In order to further increase the impact resistance of the bumper post structure 100, in one embodiment of the present application, as shown in fig. 16, a first groove 111 is formed on the first sidewall 11, and a second groove 121 corresponding to the first groove 111 is formed on the second sidewall 12. Fig. 15 is a schematic sectional view taken along line A-A in fig. 14, and as shown in fig. 14 and 15, the inner gusset 30 penetrates the pillar body 1 in the vehicle body longitudinal direction, and both sides of the inner gusset 30 in the width direction are respectively fitted into the first groove 111 and the second groove 121. Because the inner rib plate 30 completely penetrates through the column main body 1 and is embedded in the first side wall 11 and the second side wall 12, when the inner rib plate 30 is impacted, the inner rib plate 30 can be contacted with an impacting object at the first time and jointly bear impact force with the side wall of the column main body 1, so that deformation of the side wall of the column main body 1 can be reduced, and the whole compression-resistant bearing capacity of the anti-collision column structure 100 is improved. Further, the provision of the first groove 111 and the second groove 121 can restrict the displacement of the inner rib 30 inside the column main body 1, and also can facilitate the insertion of the inner rib 30 inside the column main body 1 from the first groove 111 or the second groove 121.
To facilitate insertion of the inner gusset 30 through either the first channel 111 or the second channel 121, in one embodiment, as shown in FIG. 16, the openings of both the first channel 111 and the second channel 121 are provided with chamfers 14.

Because the inner rib plates 30 are arranged in the middle of the column main body 1, when the column main body is impacted, the force can be uniformly transmitted to the side walls on two sides, so that the side walls of the column main body 1 on two sides of the inner rib plates 30 can uniformly resist the impact, and the deformation is prevented from being overlarge due to insufficient local strength. Optionally, the bottom of the inner gusset 30 is rectangular in configuration.
In one embodiment of the present application, both sides of the inner rib plate 30 are welded to the first and second side walls 11 and 12, respectively, and in order to increase the strength of the welded seam, as shown in fig. 16, the anti-collision post structure 100 further includes a welded backing plate assembly including a first backing plate 41, a second backing plate 42, a third backing plate 43, and a fourth backing plate 44 extending in the length direction of the post body 1.

By arranging the welding backing plate assembly, the welding area of the inner rib plate 30 and the first side wall 11 and the second side wall 12 can be increased, the welding quality of the root of the welding seam is improved, the welding is convenient to complete, a better welding joint is obtained, and the connection strength between the inner rib plate 30 and the first side wall 11 and the second side wall 12 is improved.

The shear block 50 extends upward from the bottom of the column body 1 along the length of the column body 1. One of the shear members 50 is snugly secured to the third side wall 13 and the other shear member 50 is snugly secured to the closure panel 20. Alternatively, the shear member 50 is generally plate-like in shape.
By providing the shear member 50 at the bottom of the column body 1, the column body 1 strength and shear load capacity can be increased, improving the impact resistance of the impact post structure 100. The shear device 50 is attached to the third side wall 13 and the closing plate 20, so that the strength in the impact direction can be improved, and the shear load capacity and compression load capacity of the column structure 100 are stronger when the column structure is impacted in the longitudinal direction of the vehicle body.
