The characteristic is that a plurality of vertical reinforcement plates are installed on the upper row of the outer side panel of the box, and a U-shaped upper hinge plate is installed on the lower end of the reinforcement plate. A U-shaped lower hinge plate is installed on the bottom plate frame under the reinforcement plate. The upper hinge plate is embedded in the lower hinge plate, and a horizontal hinge pin is installed between the upper hinge plate and the lower hinge plate. It solves the problem that the side panel reinforcement plate is built-in, the hinge and the reinforcement plate are not in the same position, and the life of the box is affected. It is particularly suitable for assembling truck boxes.

[0004] In the above-mentioned prior art, the strength is improved by strengthening the connection structure between the reinforcing plate and the side plate of the carriage.

[0024] The following is a further detailed description of the specific implementation methods of the utility model by describing the embodiments with reference to the accompanying drawings, with the aim of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the utility model concept and technical solution of the utility model and facilitating its implementation.

[0025] See also Figure 1-5A truck side plate reinforcement structure includes a reinforcement plate 2 installed on the side plate 1, the reinforcement plate 2 is divided into a middle plate 21 and side plates 22 installed on both sides of the middle plate 21, the end of the middle plate 21 is a main welding end face 23 connected to the side plate 1, the end of the side plate 22 is a side welding end face 24 connected to the side plate 1, and the middle part of the side plate 22 is provided with a welding sink 3 connected to the middle plate 21.

[0026] The cross section of the middle plate 21 is in a concave shape; the concave structure can enhance the overall strength and reduce the risk of the middle plate 21 bending and breaking.

[0027] The interface of the side plate 22 is in the shape of a strip, which facilitates the processing of the side plate 22 .

[0028] Both ends of the middle plate 21 are spot welded to the side plate 1 through the main welding end faces 23; the middle plate 21 is fixed to the side plate 1 by spot welding to reduce the contact area, thereby reducing the risk of rust.

[0029] Both ends of the side plate 22 are spot welded to the side plate 1 through the side welding end faces 24; the spot welding method is used to solve the problem of rust in the overlapping area and avoid the risk of rust.

[0030] The side panels 22 are spot-welded to the two ends of the middle panel 21 through the welding sinkers 3; the strength of the middle panel 21 is enhanced by the side panels 22, and the sinker space is small, which satisfies the spot welding operation space, and there is no redundant overlap surface, which effectively avoids the risk of rust caused by sheet metal overlap, and achieves a Y-direction overlap gap of >0mm between the remaining surfaces of the side panel 1 except the welding position and the reinforcing plate 2, that is, a non-fitting state, and completes the anti-corrosion improvement in the electrophoresis and painting processes.

[0031] Liquid leakage holes 4 are provided at both ends of the middle plate 21 to prevent liquid from accumulating at the connection between the middle plate 21 and the side plate 1 and reduce the risk of rust.

[0032] Both ends of the middle plate 21 are provided with sheet metal holes 5, which reduce the overall weight and achieve lightweight while facilitating positioning by the fixture.

[0033] The welding sink 3 is a groove sunken toward the side plate 1, which increases the operating space for spot welding and facilitates the operator to perform welding.

[0034] The connection portion between the side plate 22 and the middle plate 21 is a rounded transition structure, which reduces the risk of fracture at the connection between the side plate 22 and the middle plate 21 .

[0035] The technical effect of the utility model is: by optimizing the shape of the reinforcing plate 2 and adopting a multi-point and less-surface contact scheme, the reinforcing plate 2 is connected to the side plate 1 by spot welding, and the middle plate 21 and the side plate 22 are fixed together by spot welding, which effectively avoids the risk of rusting of sheet metal overlaps, and the sheet metal shaping surface provides strength support for the product, thereby improving corrosion resistance.
