Relevant flow guiding devices are needed to cooperate. At the same time, since the loading heights of different batches of goods are often different, in order to improve the guiding effect of the flow guiding device on the air flow, corresponding adjustment measures should be available to adapt to different usage scenarios.

[0023] The supporting component includes two sleeves 8 fixedly connected to the upper surface of the base 7, two support rods 9 being slidably connected in the two sleeves 8 respectively, a spring 10 being fixedly connected between the bottom ends of the two support rods 9 and the inner bottom surface of the sleeves 8 respectively, a second flow guide cover 11 being slidably connected in the first flow guide cover 2, and the top ends of the two support rods 9 being fixedly connected to the bottom surface of the second flow guide cover 11.

[0024] The working principle of the present utility model is as follows: When in use, the bottom plate 1 is installed above the cab of the vehicle head. When the vehicle is running, under the guidance of the slope of the first air deflector 2, the air flow can effectively reduce the resistance to the vehicle. At the same time, the adjusting mechanism can adjust the guiding height and range of the device. When it is necessary to increase the guiding height, the threaded rod 4 is rotated by turning the knob. When the threaded rod 4 rotates, the nut 6 will engage with the threaded rod 4 under the restriction of the two guide rods 12 and the two guide plates 13, and then move left and right along the threaded rod 4. When it is necessary to increase the guiding height, the nut 6 moves towards the bearing plate 5, thereby driving the base 7 to move. The movement of the base 7 drives the second air deflector 11 to move through the two sleeves 8 and the support rod 9, so that the second air deflector 11 extends out of the first air deflector 2.
