As shown in fig. 1 and 2, the present invention discloses a flow guiding device 100, which comprises a telescopic rod 110 and a flow guiding cover 120 with a variable cover surface area; the telescopic rod 110 is used for being installed at the back of a cab 210 of the truck 200, and the extension direction of the telescopic rod 110 is the same as the direction of the roof of the cab 210 of the truck 200; the two opposite sides of the air guide sleeve 120 are respectively provided with a first mounting part 121 and a second mounting part 122; the first mounting part 121 is used for being movably connected with the roof of the cab 210 of the truck 200 so that the air guide sleeve 120 can be turned relative to the cab 210 of the truck 200; the second mounting member 122 is movably connected to the telescopic end of the telescopic rod 110, so that the pod 120 can be flipped over with respect to the telescopic rod 110; when the telescopic rod 110 is extended, the air guide sleeve 120 is lifted; as the telescoping pole 110 is shortened, the pod 120 descends.
When the telescopic rod 110 is applied, the first mounting part 121 can be hinged to the top surface of the cab 210, so that the dome 120 and the cab 210 can be turned over, and similarly, the second mounting part 122 can be hinged to the telescopic end of the telescopic rod 110, so that the dome 120 and the telescopic rod 110 can be turned over, and the telescopic rod 110 is connected and fixed to the back of the cab 210 of the truck 200, and the telescopic rod 110 is vertically arranged, so that the telescopic rod 110 can be extended upwards.
As shown in fig. 1, the telescopic rod 110 is in a shortened state, so the height of the pod 120 is at the lowest position; as shown in fig. 2, at this time, the telescopic rod 110 is in an extended state, and since the area of the cover surface of the pod 120 can be changed in a matching manner, the telescopic rod 110 can drive the pod 120 to ascend, so that the height adjustment of the pod 120 is realized, even if the truck 200 is loaded with the cargo compartments 220 of different heights, the height matching between the pod 120 and the cargo compartments 220 can be adjusted, and the problem of poor flow guiding effect is avoided.
The first mounting part 121 and the second mounting part 122 are used for movably connecting components, and the hinge joint is a simple connection mode, so that the first mounting part 121 and the second mounting part 122 can be arranged as ear plates, and then the installation and fixation of the deflector 100 can be realized through components such as a hinge or a rotating shaft.
In addition, the telescopic rod 110 is used for driving the air guide sleeve 120 to move up and down, so the telescopic rod 110 can be a hydraulic telescopic rod, an electric telescopic rod or a rack telescopic rod, and the like, thereby showing that the selection of the telescopic rod 110 is not unique, and technicians can select the telescopic rod according to requirements.
A second embodiment of the deflector 100 is shown in fig. 3 to 5 and corresponds substantially to the first embodiment of the deflector 100, except that the deflector 120 comprises a first and second planar cover 123, 124; the first cover 123 is provided with a receiving groove 125, and the first mounting member 121 is arranged on the first cover 123; the second cover 124 is inserted into the receiving groove 125, and the second mounting member 122 is disposed on the second cover 124; when the telescopic rod 110 is extended, the second cover 124 is removed from the receiving groove 125; when the telescopic rod 110 is shortened, the second cover 124 moves into the receiving groove 125.

As shown in fig. 8, at this time, the height of the cargo compartment 220 is higher than the height of the air guide sleeve 120, after the position sensor 130 sends the detection result to the controller, the controller controls the telescopic rod 110 to extend, in the process, the position sensor 130 continuously detects until the height of the air guide sleeve 120 matches the height of the cargo compartment 220, and the controller controls the telescopic rod 110 to stop extending.
Similarly, as shown in fig. 9, when the height of the cargo compartment 220 is lower than the height of the air guide sleeve 120, after the position sensor 130 sends the detection result to the controller, the controller controls the telescopic rod 110 to shorten, in the process, the position sensor 130 continuously detects until the height of the air guide sleeve 120 matches the height of the cargo compartment 220, and the controller controls the telescopic rod 110 to stop shortening.
That is, the height of the air guide sleeve 120 is automatically adjusted, so that the arrangement of manual adjustment is omitted, and the adjustment accuracy of the air guide sleeve 120 is improved, thereby providing an important guarantee for the air guide effect of the air guide device 100.
