[0018] The utility model is described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] like Figure 1As shown, the body cargo box frame device 1 of the carrier vehicle of this embodiment is mainly composed of an iron fan-shaped tube 2 with a fan-shaped cavity and a corner connector 3. Twelve iron fan-shaped tubes 2 of three different lengths are arranged to form a rectangular cube frame 1 containing a rectangular plane frame in six sides. One end of the three iron fan-shaped tubes 2 at each corner of the rectangular cube frame is connected by a corner connector 3.

[0020] The fan-shaped tube of the utility model is a fan-shaped tube whose fan-shaped cavity is formed by two perpendicularly intersecting planes 21, 22 and a circular arc surface 20. Figure 2 .

[0021] In order to enhance the structural stability of the frame, a grid structure 6 is provided on the rectangular plane frame on one side. In the present embodiment, the grid structure 6 is provided on the rectangular plane frame on the lower side and is provided in the inner frame of the rectangular plane frame. The inner frame surface of the inner frame is formed by a plane 22 on the fan-shaped tube. The grid structure 6 is composed of orthogonally arranged iron reinforcement ribs 61.

[0022] The grid structure 6 of this embodiment uses four iron reinforcing ribs 61, two of which are adapted to the inner frame length of the rectangular plane frame. Two positioning holes 4 are arranged along the length direction on the two iron reinforcing ribs 61. The positioning holes 4 are used for positioning the manufacturing process when the utility model is manufactured, and for installation positioning of the utility model installed on the vehicle body. The length of the other two iron reinforcing ribs 61 is adapted to the inner frame width of the rectangular plane frame, and they are orthogonally arranged on the above two iron reinforcing ribs and welded thereto to form a grid structure in the shape of a cross. The two ends of each reinforcing rib 61 constituting the grid structure 6 are respectively welded to the inner frame surface 22 on the opposite side of the rectangular plane frame.

[0023] When making the utility model, firstly, two iron reinforcing ribs 2 provided with positioning holes 4 and having a length matching the length of the inner frame of the rectangular plane frame are arranged in parallel on the mounting platform through the positioning holes, and the spacing between the two iron reinforcing ribs 2 is set according to the spacing set by the grid structure, and the other two iron reinforcing ribs (matching the width of the inner frame of the rectangular plane frame) are orthogonally arranged on the two iron reinforcing ribs and welded to them, thereby forming a tic-tac-toe grid structure. Then, a rectangular plane frame in the lower side direction is made. This embodiment utilizes the characteristics that the length and width of the tic-tac-toe grid structure are respectively matched with the length and width of the inner frame of the rectangular plane frame, and uses it as a positioning member for making the rectangular plane frame in the lower side direction. The fan-shaped tubes constituting the rectangular plane frame are positioned in the orthogonal direction of the grid structure and the orthogonal adjacent fan-shaped tubes are connected by the corner connectors, thereby enclosing the rectangular plane frame in the lower side direction. Then, the fan-shaped tubes and the corner connectors are connected based on the rectangular plane frame in the lower side direction to finally form a vehicle body cargo box frame device.

[0024] The iron sector tube 2 of the utility model is provided with a leakage hole 5, which is arranged on two perpendicular intersecting planes of the iron sector tube 2. When the electrophoretic liquid flows through the leakage hole 5, the gas in the cargo box frame can be discharged at the same time. The positioning hole 4 and the leakage hole 5 of the present embodiment are both formed by machining.

[0025] The corner connector of this embodiment is a spherical segment having one eighth of a sphere, the spherical surface of which matches the arc of the arc surface on the sector tube, and the three mutually perpendicular planes 31, 32, 33 on the spherical segment respectively match the sector shape of the above-mentioned sector cavity (see Figure 2 ), and the three mutually perpendicularly intersecting planes are respectively butt-welded to one end of the three fan-shaped tubes in a shape-matched manner.

[0026] The corner connector of this embodiment is made by stamping sheet metal, and the iron fan-shaped tube is formed by rolling.

[0027] The technical solution of the present utility model is not limited to the above-mentioned embodiments, and any technical solution obtained by equivalent replacement methods falls within the scope of protection required by the present invention.
