[0018] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0019] The present application embodiment discloses a safety support device for a cargo box of a rear-rolling vehicle, referring to Figure 1 , including a cargo vehicle and a cargo bucket 2. The cargo vehicle has a subframe 1 located behind the front of the vehicle. The cargo bucket 2 is rotatably mounted on the subframe 1 of the cargo vehicle. The rotating shaft 51 of the cargo bucket 2 is located at the rear of the cargo vehicle. The subframe 1 is provided with a piston cylinder 3 for driving the cargo bucket 2 to rotate. One end of the piston cylinder 3 is hinged to the subframe 1, and the other end is hinged to one end of the cargo bucket 2 away from the hinge shaft. The piston rod of the piston cylinder 3 is extended to lift the cargo bucket 2.

[0020] Reference Figure 2 and Figure 3 In the embodiment of the present application, the subframe 1 on the cargo vehicle is installed with a base 4, a support rod 5 is hingedly installed on the base 4, a support portion 6 is fixedly installed on the bottom wall of the cargo bucket 2, and a support seat 7 is provided at the end of the support rod 5 away from the base 4. After the piston cylinder 3 lifts the cargo bucket 2, the support rod 5 can be rotated to be supported under the cargo bucket 2, and the support seat 7 on the support rod 5 can cooperate with the support portion 6 on the cargo bucket 2. When the support seat 7 and the support portion 6 are stably matched, even if the hydraulic cylinder loses power, the support rod 5 can still support the cargo bucket 2, thereby improving the support safety of the cargo bucket 2.

[0021] In the embodiment of the present application, the support portion 6 of the bottom wall of the cargo bucket 2 is a rectangular tube, which is welded and fixed to the cargo bucket 2 along the width direction of the cargo bucket 2. A first slot 71 matching the shape of the rectangular tube is provided on the support seat 7, and the first slot 71 has two openings. When the support rod 5 rotates upward, the first slot 71 on the support seat 7 cooperates with the rectangular tube.

[0022] In the embodiment of the present application, when the support rod 5 rotates to the support seat 7 and the support part 6, the support rod 5 is supported on the movable bottom wall at 90 degrees. Further, a side edge of the first slot 71 on the support seat 7 is provided with a limited warping edge 72. When the support part 6 and the support seat 7 are matched, the limited warping edge 72 is located at a side edge of the first slot 71 close to the hinge axis of the cargo bucket 2, and the height of the limited warping edge 72 is less than the height of the side edge of the first slot 71 away from the hinge axis of the cargo bucket 2. By providing the limited warping edge 72, the support stability of the support rod 5 in the state of supporting the cargo bucket 2 can be improved.

[0023] Reference Figure 4 In the embodiment of the present application, a holder 8 is provided on the side of the base 4 on the sub-frame 1 away from the hinge axis of the cargo box 2. The holder 8 is flush with the base 4. A second slot 81 is provided on the holder 8 for the support rod 5 to be embedded in when it is rotated and lowered. When the support rod 5 is rotated and laid flat from under the cargo box 2, the support rod 5 can be embedded in the holder 8 to facilitate the storage of the support rod 5.

[0024] Furthermore, the support rod 5 can be made of a rectangular tube, which has good structural strength. On the inner walls of both sides of the second slot 81 on the base 8, there are protruding elastic clamping parts 82, which are formed by bending the metal sheet with the base 8, and are used to clamp the support rod 5 in a horizontal state. When the support rod 5 is clamped in the second slot 81, the elastic clamping part 82 abuts against the upper edge of the support rod 5 to limit the support rod 5 from being separated from the second slot 81, thereby improving the stability of the support rod during the driving of the vehicle.

[0025] Furthermore, a rotating shaft is fixedly connected to one end of the support rod 5 close to the base 4, and the rotating shaft is parallel to the hinge axis of the cargo bucket 2. An "L"-shaped guide groove 41 is opened on the side wall of the base 4, and one end of the guide groove 41 is horizontally facing the hinge axis of the cargo bucket 2, and the other end is vertically facing upward. The rotating shaft is movably arranged in the guide groove 41, and the rotating shaft can rotate in the guide groove 41, and move in the guide groove 41 along the length direction of the guide groove 41.

[0026] When the support part 6 cooperates with the support seat 7, the rotation axis is located at one end of the hinge axis of the guide toward the cargo bucket 2, and when the rotation axis 51 is located at the higher end of the guide groove 41, the support rod 5 can rotate relative to the base 4, and the distance from the axis of the rotation axis 51 to the end of the support rod 5 close to the base 4 is slightly greater than the vertical distance from the center line of the horizontal section of the guide groove 41 to the inner bottom wall of the base 4, and the distance from the axis of the rotation axis 51 to the end of the support rod 5 close to the base 4 is less than the vertical distance from the top midpoint of the guide groove 41 to the inner bottom wall of the seat, so that the rotation axis 51 is located in the horizontal section of the guide groove 41 and the end face of the support rod 5 cooperates with the inner bottom wall of the base 4 to limit the rotation of the support rod 5. In this way, when the support rod 5 and the cargo bucket 2 are dismantled, the support rod 5 needs to be translated until the rotation axis 51 is located at the top of the guide groove 41 before the support rod 5 can be rotated to lay the support flat, further improving the stability of the support rod 5 when supporting the cargo bucket 2.
