[0015] Referring to Figures 1-3 The folding side skirt device of the utility model comprises main frame 1, is equipped with support arm 2 and side skirt plate 3 respectively on the left and right sides of main frame 1, and the left and right direction extension installation guide rail 4 is arranged on main frame 1, preferably, the installation guide rail 4 has two, is arranged respectively in the upper portion and lower portion of main frame 1.
[0016] The left and right ends of installation guide rail 4 are hinged with the one end of left side support arm and right side support arm respectively, and the outer side of left side support arm is fixedly connected with left side side skirt plate, and the outer side of right side support arm is fixedly connected with right side side skirt plate. Installation seat 5 is further arranged respectively at the position close to the end of the left and right sides of installation guide rail 4.
[0017] Electric telescopic rod 6 is arranged between the other end of left side support arm and left side installation seat and between the other end of right side support arm and right side installation seat respectively, and the two ends of electric telescopic rod 6 are hinged with corresponding installation seat 5 and support arm respectively.
[0018] When the length of electric telescopic rod telescopes, the side skirt plate 3 rotates relative to the main frame 1, so that the side skirt plate 3 is unfolded outward to a certain angle or is folded back inward.
[0019] Preferably, the mounting rail 4 has a containing groove 7, when the side skirt plate 3 is folded, the electric telescopic rod 6 is located in the containing groove 7, so that the side skirt plate 3 is closer to the mounting frame, and the occupied space is reduced.
[0020] Referring to Figure 4 The schematic view of the automatic folding side skirt device installed on the truck, the main frame 1 is fixed behind the vehicle head, the side skirt plate 3 is located between the vehicle head and the hanging box, and is used for shielding the gap between the vehicle head and the hanging box.
[0021] Specifically, during the vehicle driving process, the control unit monitors the vehicle speed in real time. When the steering angle is less than 15°, and the vehicle speed is more than 60km / h, the control unit sends an instruction to the electric supporting rod, the electric supporting rod pushes the side skirt plate supporting frame to open, and the side skirt plate opens and closes different angles according to the actual size of the hanging box, reduces the disturbance between the vehicle head and the hanging box, and reduces the wind resistance. When the steering angle is more than 15°, or the vehicle speed is less than 60km / h, the electric supporting rod is controlled to retract, and the side skirt plate is folded to the position flush with the back of the vehicle head, without affecting the turning and operation of the hanging box.
