DETAILED DESCRIPTION

[0015] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. Unless otherwise specified, the raw materials and equipment used can be purchased from the market or are commonly used in the art. The methods in the embodiments are conventional methods in the art unless otherwise specified. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0016] A cargo box side door structure comprises a door frame, a left door panel 4 and a right door panel 5. The door frame is divided into a top frame 1, two side frames 2 and a bottom frame 3. A rain shielding groove 12 is horizontally arranged on the outer wall of the top frame 1. Both ends of the rain shielding groove 12 exceed the two door panels and bend downward to shield the two door panels from rain and drain water to both sides. A horizontal guide groove 11 is arranged on the bottom edge of the top frame 1, and a vertical guide groove 21 is arranged on the inner edge of the side frame 2. The end of the horizontal guide groove 11 is connected with the top of the vertical guide groove 21. A horizontal plate 41 is arranged on the top section of the inner wall of the left door panel 4, and a vertical plate 42 is arranged on the left section of the inner wall. The top of the vertical plate 1 42 is connected with the left end of the horizontal plate 1 41, and the right section of the inner wall of the left door panel 4 is provided with a vertical coupling groove 43, which extends to the right beyond the left door panel 4; the top section of the inner wall of the right door panel 5 is provided with a horizontal plate 2 51, and the right section of the inner wall is provided with a vertical plate 2 52, and the top of the vertical plate 2 52 is connected with the right end of the horizontal plate 2 51; the left section of the inner wall of the right door panel 5 is provided with a coupling vertical plate 53, and the top of the coupling vertical plate 53 is connected with the left end of the horizontal plate 2 51; the middle section of the horizontal guide groove 11 has a fracture 111; the bottom outer walls of the left door panel 4 and the right door panel 5 have a skirt panel 6 extending downward.

[0017] When the door is closed, the left door panel 4 and the right door panel 5 cover the inner edge of the door frame, and the left edge of the right door panel 5 covers the right edge of the left door panel 4. The horizontal plate 1 41 and the horizontal plate 2 51 are located in the horizontal guide groove 11, which can guide the rainwater invading from above to both sides. The vertical plate 1 42 and the vertical plate 2 52 are respectively located in the vertical guide groove 21 on their sides. The break 111 is located above the combining groove 43 and is a narrower opening. The combining vertical plate 53 passes through the break 111 and is located in the combining groove 43, which can guide the rainwater downward. Even if the break 111 drips downward, the water enters the combining groove 43. The skirt board 6 fits the bottom frame 3, and the rainwater on the outer surface of the door panel slides off the skirt board 6. The side of the transverse plate 1 41 and the transverse plate 2 51 facing the inside of the box is tilted downward, and the right end of the transverse plate 1 41 is located above the coupling groove 43 and tilted downward, so that the water on the transverse plate 1 41 and the transverse plate 2 51 can flow smoothly into the transverse guide groove 11 and the coupling groove 43.

[0018] In order to further prevent rainwater from flowing in, the notch of the vertical guide groove 21 close to the frame is bent inward to form a rivet edge 211, and the combined groove 43 has a rivet edge 431; in the closed state, the vertical plate 1 42 and the vertical plate 2 52 extend inward beyond the rivet edge 211, and the combined vertical plate 53 extends inward beyond the rivet edge 431, thereby increasing the resistance to rainwater.

[0019] A cargo box side door structure, working principle: First, close the left door panel 4. During the closing process, the horizontal plate 1 41 enters the horizontal guide groove 11, and the vertical plate 1 42 enters the vertical guide groove 21 of the left side frame 2; then close the right door panel 5. During the closing process, the horizontal plate 2 51 enters the horizontal guide groove 11, and the vertical plate 2 52 enters the vertical guide groove 21 of the right side frame 2, and enters the combination groove 43 in combination with the vertical plate 53; in the final closed state, the left door panel 4 and the right door panel 5 cover the inner edge of the door frame, the left edge of the right door panel 5 covers the right edge of the left door panel 4, and the horizontal plate 1 41 and the horizontal plate 2 51 are located in the horizontal guide groove 11. The rainwater intruding from the top of the door panel can be guided to both sides. The vertical plate 1 42 and the vertical plate 2 52 are respectively located in the vertical guide groove 21 on their sides, and the vertical plate 53 is located in the combining groove 43 to guide the rainwater downward. The skirt board 6 fits the bottom frame 3, and the rainwater on the outer surface of the door panel slides off the skirt board 6; in particular, since the side of the horizontal plate 1 41 and the horizontal plate 2 51 facing the inside of the box is tilted downward, and the right end of the horizontal plate 1 41 is located above the combining groove 43 and tilted downward, the water on the horizontal plate 1 41 and the horizontal plate 2 51 can smoothly flow into the horizontal guide groove 11 and the combining groove 43.

[0020] A cargo box, the side wall of which is equipped with the cargo box side door structure. Due to the side door structure, the outer periphery of the door panel has no black edges, the appearance is more beautiful, and the maintenance frequency is lower.

[0021] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the above embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
