Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0013] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0015] See Figure 1-4 A dump truck rear panel tipping mechanism includes a vehicle body 1. Two columns 2 are provided at the ends of the vehicle body 1. A U-shaped support 3 is fixedly connected to each column 2. A rear panel 5 is provided between the two U-shaped support 3. A connecting shaft 4 is fixedly connected to each end of the rear panel 5. The connecting shaft 4 is connected to the U-shaped support 3.

[0016] The dump truck with this structure can automatically open the rear panel 5 under the influence of gravity as the vehicle body 1 rises and falls, and can automatically close when the vehicle body 1 returns to its original position. It can flip smoothly and use the column 2 to fix the U-shaped support 3. Then the rear panel 5 is hung on the U-shaped support 3 to avoid the accumulation of mud or debris between the rear panel 5 and the column 2. The operation is simple and convenient.

[0017] In some embodiments, the operator can create grooves on opposite sides of the two pillars 2 of the vehicle body 1, and then place the U-shaped support 3 within the grooves, as shown in the attached figure. Figure 1 The structure shown moves the U-shaped support 3, connecting shaft 4, and rear plate 5 to the left into the range of column 2, so that the connecting shaft 4 is rotatably connected to column 2, i.e., with the attached... Figure 1 From this perspective, the column 2 can completely cover the U-shaped support 3, the connecting shaft 4, and the rear plate 5, thereby reducing the exposure of components and improving service life.

[0018] In some embodiments, each of the U-shaped support members 3 includes two support plates, and a retaining plate is rotatably connected to each of the connecting shafts 4, with the retaining plate located between the two support plates. The two support plates and the retaining plate can limit the position of the rear plate 5, preventing the rear plate 5 from moving to one side due to vibration during use, which would cause the connecting shaft 4 of the rear plate 5 to detach from the U-shaped support member 3 and fall off.

[0019] In some embodiments, a sealing plate 6 is sleeved at each end of the connecting shaft 4, and the two sealing plates 6 are respectively connected to one of the U-shaped support members 3. The sealing plates 6 are welded together with the U-shaped support members 3, thereby blocking the sides of the U-shaped support members 3 on both sides of the connecting shaft 4. This not only prevents the rear plate 5 from running out, but also prevents mud and sand from entering the U-shaped support members 3 and affecting the rotation of the rear plate 5.

[0020] In some embodiments, the clamping plate is made of rubber. When the rubber clamping plate is placed between the two support plates, it can increase the friction between the clamping plate and the support plates, thereby making the rear plate 5 more securely engaged and less likely to jump off due to vibration.

[0021] In some embodiments, a stop bar 51 is provided at the end of the rear panel 5, and a fixing member 7 is provided on the vehicle body 1. The fixing member 7 includes a pull rod 71 and a hook 72. The hook 72 is connected to the vehicle body 1 through a torsion spring and abuts against the stop bar 51. The pull rod 71 is connected to the front end of the vehicle body 1 and is rotatably connected to the hook 72. When the vehicle body 1 is lifted by the car cylinder, the front end of the vehicle body 1 will pull the pull rod 71, causing the pull rod 71 to drive the hook 72 to rotate. The hook 72 is then driven and no longer abuts against the stop bar 51 of the rear panel 5, thereby opening the rear panel 5 and dumping the objects inside the vehicle body 1. When the vehicle body 1 stops rising and returns to its original position, the stop bar 51 on the rear panel 5 will press against the hook 72, thereby causing the hook 72 to rotate. Then the stop bar 51 can return to its original position, and the hook 72 abuts against the stop bar 51 again through the torsion spring, thus fixing the rear panel 5.

[0022] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
