Referring to fig. 4, 5 and 6, fig. 4 is a schematic view of an end beam structure of a container truck according to an embodiment of the present invention; FIG. 5 is a schematic view of the container car end beam structure of FIG. 4 from another perspective; fig. 6 is a partially enlarged view of fig. 5.

As shown in the drawings, in the present embodiment, the end beam structure of the container vehicle is mainly formed by welding an end plate 11, an upper cover plate 12 and a lower cover plate 13, a U-shaped notch 14 with a downward opening is formed in the middle of the lower edge of the end plate 11, and the length of the lower cover plate 13 in the length direction of the vehicle body is smaller than that of the upper cover plate 12 in the length direction of the vehicle body.

Wherein, upper cover plate 12 includes upper left cover plate and upper right cover plate, lower cover plate 13 includes lower left cover plate and lower right cover plate, the distance that has the interval between upper left cover plate and the upper right cover plate, also have the distance of interval between lower left cover plate and the lower right cover plate, so that hold and weld draw beam or well roof beam, upper left cover plate and upper right cover plate are inwards retracted certain distance respectively for the left edge and the right edge of end plate 11, lower left cover plate and lower right cover plate are inwards retracted certain distance also respectively for the left edge and the right edge of end plate 11, so that place and weld the curb girder.

The end plate 11 is a laterally extended integral end plate having a substantially rectangular shape with a predetermined width and height, and an upper portion of the end plate 11 integrally protrudes from an upper plane of the upper cover plate 12 to form a door stopper or at least a portion of the door stopper at an end portion of the vehicle body, and if the formed door stopper is a box-type structure, the end plate 11 protrudes from an upper portion of the upper plane of the upper cover plate 12 to form a portion of the box-type structure.

Specifically, the door stop is formed by welding an inverted "L" shaped sealing plate 15 to the upper portion of the end plate 11, the upper portion of the end plate 11 protruding out of the upper plane of the upper cover plate 12 and the "L" shaped sealing plate 15 are welded to form a box-shaped structure, the upper portion of the end plate 11 forms an outer side plate of the door stop, the "L" shaped sealing plate 15 forms an inner side plate of the door stop, the bent upper edge of the "L" shaped sealing plate 15 is welded to the inner side of the upper edge of the end plate 11, and the bent lower edge of the "L" shaped sealing plate 15 is welded to the upper surface of the upper cover plate 12.

In addition, in order to form a relatively closed box-shaped structure, the door stop is further provided with side sealing plates 16 positioned at two ends, the shape of each side sealing plate 16 is matched with the cross-sectional shape of a cavity formed by bending the end plate 11 and the L-shaped sealing plate 15, and the side sealing plates 16 are simultaneously welded and connected to the upper part of the end plate 11 and the L-shaped sealing plate 15.

Of course, the side sealing plate 16 may be formed by bending both ends of the "L" shaped sealing plate 15 in the end plate direction, and then welded to the end plate 11. This structure helps to reduce the number of welds and parts, while improving the structural strength of the door shield.

From the dimensional parameters, the door stopper is similar to a short end wall structure, and the height of the end plate 11 protruding out of the upper plane of the upper cover plate 12 can be controlled within 1/4-1/2 of the overall height of the end plate 11.

In another embodiment, the inner surface of the door stop has an angle inclined from top to bottom toward the center of the vehicle body, for example, the inner surface of the door stop is inclined at an angle of 5 ° to 10 °, i.e., the vertical portion of the "L" shaped sealing plate 15 is inclined at an angle of 5 ° to 10 °. The inner vertical surface of the door shield is designed to be inclined inwards, so that the container can be assisted to lock and guide through the inclined surface, corner pieces at the end part of the container and a lock head of the container are accurately connected together, and the aim of realizing multiple functions by one component is fulfilled.

In addition, in order to improve the structural strength of the door shield and prevent the door shield from deforming and damaging under the conditions of impact and the like in the using process, rib plates arranged at intervals can be additionally arranged in the inner space of the door shield, and can be parallel to the side sealing plates or perpendicular to the side sealing plates 16, one part of the rib plates can be parallel to the side sealing plates 16, the other part of the rib plates can be perpendicular to the side sealing plates 16, and a certain angle can be formed between the rib plates and the side sealing plates 16.

The above embodiments are merely preferred embodiments of the present invention, and are not limited thereto, and different embodiments can be obtained by performing targeted adjustment according to actual needs. For example, the "L" shaped closing plate 15 is formed by welding together a horizontal plate and a vertical plate, or the "L" shaped closing plate 15 is divided into two pieces from the middle, forming two box-shaped structures on the left and right with the end plate 11, and so on. This is not illustrated here, since many implementations are possible.

This container car end beam structure adopts the structure that 11 upper portions of end plate are whole to be higher than upper cover plate 12, than the local protruding structure in middle part, the technology has been simplified, and the cost is saved, and, 11 upper portions of end plate and 15 group welding of "L" type shrouding become the box structure, than the local protruding structure in middle part, the vertical load bearing capacity of end beam has been strengthened, the whole vertical rigidity of end beam has been improved, solve partial vehicle end beam and bear the problem that bears vertical load bearing capacity weak, compare with the structure that traditional foundry goods L type door shield welded the end beam, the welding volume has been reduced, also can play simultaneously and prevent that traditional foundry goods door shield from causing the accident to drop because welding quality is poor.
