[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1 Reference Figures 1 to 4 This embodiment provides a box-type rear-tipping transport vehicle, which includes a frame and a cargo box mounted on the frame. The rear of the cargo box is rotatably mounted on the rear of the frame, and a rear-tipping lifting device is provided between the frame and the cargo box. The improvement lies in that the cargo box includes a cargo box body 1 and a rotating beam 4 located at the lower rear of the cargo box body 1 and arranged laterally. A strip-shaped groove is provided at the lower rear of the cargo box body, and the rotating beam is located within the strip-shaped groove. The rotating beam 4 is mounted on the rear of the frame. This mounting method can be container lock mounting, bolt connection, snap-fit, etc. In this embodiment, the rotating beam 4 is a bent component with an L-shaped cross-section. The bent component includes a base plate 5 located at the bottom and fixed to the frame. The rotating beam 4 is fixed to the frame by the base plate 5. A rear plate 6 extending upward is provided at the rear of the base plate 5. The rear plate 6 covers the rear of the rotating beam 4, so that the rotating beam 4 and the rear of the carriage body 1 form a continuous flat surface. A hinge connector is provided between the rear plate 6 and the base plate 5. The hinge connector is located within the vertical angular space enclosed by the base plate 5 and the rear plate 6. The carriage body is rotatably mounted on the hinge connector.

[0020] The rear-tipping van provided by this utility model features a rotating beam 4 at the lower rear of the van body 1. The rotating beam 4 and the van body 1 form the van body. When the van body is fixed to the frame, the rear plate 6 of the rotating beam 4 and the rear of the van body 1 form a flat surface, and the bottom plate of the rotating beam and the bottom plate of the van body also form a basically horizontal flat surface. The special rotating structure of the rotating beam 4 is difficult to detect without close observation. When tipping is required, the rotating beam 4 remains stationary, while the van body 1 can rotate around the rotating beam 4 as the rotation center. The rotating connection of the van body is set on the rotating beam 4, eliminating the need for modifications to the frame and reducing the difficulty of promoting this rear-tipping van.

[0021] Specifically, in this embodiment, a rear side beam is provided at the rear of the frame, and the bent component is installed on the frame using container locks. That is, the frame can be a skeleton vehicle for transporting containers, with container locks provided on the rear side beam of the skeleton vehicle, and the bottom plate 5 of the bent component is fixed to the rear side beam using the container locks.

[0022] Specifically, in this embodiment, the hinge connector includes two first hinge plates 7. The lower and rear sides of the first hinge plates 7 are respectively connected to the bottom plate 5 and the rear plate 6. This arrangement can improve the strength of the hinge connector. Two second hinge plates 8 are provided at the lower rear part of the carriage body. The second hinge plates 8 are located in the middle of the two first hinge plates 7 or on both sides of the two first hinge plates 7. A pivot is also provided between the first hinge plates 7 and the second hinge plates 8.

[0023] Specifically, in this embodiment, the rotating beam 4 also integrates a locking structure for the rear door. A telescopic rod 10 is provided between the bottom plate 5 and the rear plate 6. The telescopic rod 10 is connected to a telescopic drive device 13, and multiple hook plates are provided on the telescopic rod 10. The rear plate 6 has a strip-shaped hole at the corresponding position of the hook plate, and the hook plate extends backward from the strip-shaped hole and is located at the rear of the rear plate 6. A flip door 2 is provided at the rear of the carriage, and a downwardly extending lock plate 3 is provided at the lower part of the flip door 2. When the strip-shaped hole moves, the hook plate can engage or disengage from the lock plate 3. When the telescopic rod 10 extends or retracts, it drives the hook plate to move left and right within the strip-shaped hole. The hook plate extends out of the strip-shaped hole and fits against the rear opening of the carriage body 1 when the flip door 2 is closed. At this time, the hook plate can move to the rear of the lock plate 3, thereby preventing the locking mechanism from flipping backward, and finally locking the flip door 2. Of course, when it is necessary to open the flip door 2, the telescopic rod 10 also needs to extend or retract to move the hook plate away from the lock plate 3. The telescopic rod 10 is located inside the rotating beam 4. The rotating beam 4 can protect the telescopic rod 10 and other structures, and also prevent the various parts used for locking from being exposed.

[0024] More specifically, in this embodiment, the hook plate includes a connecting part 11 connected to the telescopic rod 10 and an extension plate 12 extending to the left or right along the rear plate. The telescopic rod 10 is located inside the rotating beam 4, while the extension plate 12 is located at the rear of the rotating beam 4, and the telescopic rod 10 and the extension plate 12 are connected by the connecting part 11.

[0025] More specifically, in this embodiment, the hinge connector includes a first hinge plate 7, the lower side and the rear side of the first hinge plate 7 are respectively connected to the base plate 5 and the rear plate 6; in order to enable the telescopic rod 10 to move within the rotating beam 4 along a preset track, the first hinge plate 7 is provided with a telescopic rod 10 hole 9, and the telescopic rod 10 hole 9 can move left and right within the telescopic rod 10 hole 9.

[0026] Specifically, in this embodiment, the upper part of the rear plate 6 is also provided with an inclined upward and forward extending abutment plate 14, which abuts against the lower rear part of the carriage body. By providing the abutment plate 14, the gap between the rotating beam 4 and the carriage body 1 can be effectively sealed. At the same time, the inclined upward and forward extension of the abutment plate 14 can prevent interference between the abutment plate 14 and the rotation of the carriage body 1.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
