Exemplary embodiments that embody features and advantages of the present invention will be described in detail in the following description. It is to be understood that the invention is capable of other and different embodiments and its several details are capable of modification without departing from the scope of the invention, and that the description and drawings are to be regarded as illustrative in nature and not as restrictive.

For further explanation of the principles and construction of the present invention, reference will now be made in detail to the preferred embodiments of the present invention, which are illustrated in the accompanying drawings.

The utility model provides a self-discharging vehicle, which comprises a chassis and a self-discharging carriage arranged on the chassis.

The chassis comprises a plurality of longitudinal beams and a plurality of cross beams, and the cross beams are connected with the longitudinal beams in a mutually perpendicular mode. For convenience of description, the length direction of the chassis is defined as the longitudinal direction, and the width direction is defined as the transverse direction.

The self-discharging carriage is arranged on the chassis. Specifically, referring to fig. 1, the dump body 1 includes a bottom plate 12 and two side plates 11.

Referring to fig. 1, 2 and 3, the side plates 11 each include a lap 111 at the bottom, an extension 113 at the top, and a connecting portion 112 connecting the lap 111 and the extension 113.

In actual use, the lap joint portion 111 is located on the chassis, and specifically includes a base plate 1111 and flanges 1112 respectively arranged at two ends of the base plate 1111. The substrate 1111 is plate-shaped and horizontally disposed. The flange 1112 is inclined from bottom to top in a direction away from the base 1111. Specifically, with reference to the direction of fig. 2, the flange 1112 located on the outer side, i.e., on the left side in the figure, is inclined from bottom to top to left, and the flange 1112 located on the inner side, i.e., on the right side in the figure, is inclined from bottom to top to right.

Specifically, in this embodiment, the included angle between the flange 1112 and the base 1111 is an obtuse angle. Further, the two flanges 1112 are symmetrically arranged.

The above-described structure of the overlapping portion 111 allows the bottom of the side panel 11 to constitute a C-shaped beam for overlapping with the bottom panel 12.

In this embodiment, the tops of the two flanges 1112 are at the same height. In other embodiments, the tops of the two flanges 1112 may be located at different heights.

The connecting portion 112 protrudes outwardly beyond the bridging portion 111. The inner and outer positions are defined as inner positions with reference to the usage state of the dump body 1 and as outer positions with reference to the area enclosed by the side plates 11.

Specifically, the connecting portion 112 includes a connecting plate 1121, and a first folding edge 1122 and a second folding edge 1123 respectively arranged at two ends of the connecting plate 1121. The connection plate 1121 is plate-shaped and extends vertically. The first folding edge 1122 is located at the top of the connecting plate 1121 and is inclined inward from bottom to top to form a first folding portion. The angle between the first folding edge 1122 and the connecting plate 1121 is obtuse.

The second bending edge 1123 is located at the bottom of the connection plate 1121 and is inclined inward from top to bottom to form a second bending portion. The included angle between the second flange 1123 and the connection plate 1121 is an obtuse angle.

The second flange 1123 is connected to the flange 1112 located outside the overlapping portion 111. Further, the second flange 1123 and the overlapping portion 111 are located on the same straight line, and are integrated.

The extension 113 is located above the connection portion 112. Specifically, the extending portion 113 is parallel to the connecting plate 1121, that is, the extending portion 113 extends in the vertical direction. The extension portion 113 is connected to the top of the first fold 1122. So that the connection portion 112 protrudes outward with respect to the extension portion 113.

In this embodiment, the side plate 11 is integrally formed by bending. The bottom plate 12 is plate-shaped and horizontally disposed between the two side plates 11. Specifically, both ends of the bottom plate 12 are overlapped with the overlapping parts 111 of the side plates 11, respectively, and the bottom plate 12 is located above the overlapping parts 111.

Further, referring to fig. 1 and 2, the bottom plate 12 includes a bottom plate body 121 and two folding edges disposed at two ends of the bottom plate body 121. In the present embodiment, both of the two folded edges are bent upward. The two folded edges are respectively a third folded edge 122 and a fourth folded edge 123. An included angle between the third folded edge 122 and the bottom plate body 121 is an obtuse angle, and an included angle between the fourth folded edge 123 and the bottom plate body 121 is an obtuse angle.

The third folding edge 122 and the fourth folding edge 123 are respectively attached to the second folding edges 1123 of the two side panels 11. Specifically, with reference to the direction of view 1, the third flap 122 is located on the left side in the drawing, and the fourth flap is located on the right side in the drawing. The third folded edge 122 is attached to the second folded edge 1123 of the side panel 11 on the left side, and the fourth folded edge is attached to the second folded edge 1123 of the side panel 11 on the right side.

Referring to fig. 1, when the bottom plate 12 is connected to the side plates 11, the third folded edge 122 and the fourth folded edge 123 are respectively attached to the second folded edges 1123 of the side plates 11, and both ends of the bottom plate body 121 are respectively connected to the overlapping portions 111 of the side plates 11.

In this embodiment, the bottom plate 12 is welded to the side plate 11. With the structure of the side plate 11 and the bottom plate 12 in this embodiment, two welding seams are respectively formed at two ends of the bottom plate 12, so that the welding seams at two ends of the bottom plate 12 are relatively reduced.

The connection of the bottom plate 12 and the overlapping part 111 enables the bottom plate 12 to be located between the two side plates 11, so that the overlapping part 111 of the side plates 11 can be used as a lower cross beam and an outer side edge beam, and the functions of supporting the bottom plate 12 and protecting the bottom plate 12 are realized.

In addition, the bottom plate 12 is lapped with the lapping part 111, so that the bottom plate 12 does not affect the bearing and the strength of the connecting part 112 and the extending part 113, the occurrence of the cage expansion can be effectively prevented, and the structure is more stable.

In this embodiment, the distance between the two connection plates 1121 of the dump truck body 1 is the largest, that is, the widest position of the dump truck body 1 is configured. Compared with the rectangular dump body 1 in the related art, the dump body 1 in the embodiment has a larger internal volume because the width of the beam at the rectangular body side plate 11 is eliminated. Under the condition that the volume of the self-discharging carriage 1 meets the national standard, the height is lower, so that the gravity center is lower after the cargoes are loaded, and the self-discharging carriage runs stably.

In a further exemplary embodiment, the side plates 11 may also be shaped by a welded connection. Specifically, the extending portion 113 and the connecting portion 112 of the side plate are integrally bent and formed, the overlapping portion 111 of the side plate 11 is independently bent and formed, and the integrally formed extending portion 113 and overlapping portion 112 are welded and connected to the overlapping portion 111, thereby obtaining the side plate 11. When welding, the end of the second flange 1123 of the connecting portion 112 may be butt-welded to the end of the flange 1112 located outside the overlapping portion 111, or the second flange 1123 may be lap-welded to the flange 1112 located outside, for example, the flange 1112 located outside or inside the second flange 1123.

Specifically, in operation, the lap joint portion 111 may be welded to the bottom plate 12, and then the lap joint portion 11 may be welded to the connecting portion 112.
