The multi-link structure is interconnected with each other and the cover assembly is closed or opened with the flatbed vehicle body 1 as the base point, thereby realizing the covering operation or the uncovering operation, which is convenient for shielding the plate on the flatbed vehicle body 1 to prevent rain or to achieve heat preservation; at the same time, the folding component can drive the cover assembly body to fold or unfold while the cover assembly rotates, thereby reducing the space occupied by the cover assembly during the covering process and improving practicality.

[0028] In the flatbed truck covering device of this embodiment, the cover assembly includes a hinged first cover 2 and a second cover 3, the first cover 2 is rotatably connected to the edge of the flatbed truck body 1, and the first cover 2 and the second cover 3 are driven by the folding assembly to be folded or unfolded.

[0029] A two-part hinged structure is set up. When the first cover plate 2 rotates around the flatbed vehicle body 1, the second cover plate 3 is driven to flip around the first cover plate 1 through the folding assembly, so that the cover plate assembly can be rotated and opened as a whole during the unfolding process, and the first cover plate 2 and the second cover plate 3 are folded at the same time, reducing the occupied space after the cover plate assembly is unfolded, making it convenient for the staff to unload or load materials.

[0031] Through the above structure, the folding assembly and the cover assembly form a quadrilateral structure, the first connecting rod 4 and the second connecting rod 5 rotate relative to each other to change the angle, driving the cover assembly connected thereto to change the angle to achieve folding or unfolding, the transmission assembly drives the folding assembly to move as a whole, and the folding assembly pushes the cover assembly to rotate on the flatbed vehicle body 1 while folding or opening.

[0032] In the flatbed truck covering device of this embodiment, the transmission assembly includes a first transmission rod 6, one end of which is rotatably connected to the flatbed truck body 1, and the other end is rotatably connected to the folding assembly. The first transmission rod 6 rotates to drive the folding assembly to move to achieve folding or unfolding of the cover assembly.

[0033] Specifically, the first transmission rod 6 is connected to the first connecting rod 4 and the second connecting rod 5 through the same rotating pin shaft, and a quadrilateral is formed between the first transmission rod 6, the flatbed vehicle body 1, the first connecting rod 4 and the first cover plate 2. When the driving component drives the first transmission rod 6 to rotate on the flatbed vehicle body 1, it drives the folding component to move and further realizes the rotation of the cover plate assembly to achieve the purpose of covering or opening.

[0034] In the flatbed truck covering device of this embodiment, the transmission assembly further comprises a second transmission rod 7, one end of the second transmission rod 7 is connected to the first transmission rod 6, and the other end is connected to the driving assembly.
