[0056] Please refer to Figure 7 、 Figure 8 and Figure 9 , the expansion pins, the rotating shaft and the plurality of lifting holes on the first bottom plate 22, and the first rotating shaft hole 242 on the first support 24 are taken as examples, specifically, the expansion pins, the rotating shaft and the plurality of lifting holes on the first bottom plate 22 are respectively a first expansion pin 221, a first rotating shaft 222 and a first lifting hole 223, and the head of the first expansion pin 221 is provided with an elastic clamping jaw, and the first rotating shaft 222 is provided with an umbrella-shaped buckle / barb.
[0057] The first rotating shaft 222 can be compressed in the radial direction and can be elastically expanded, so that the first rotating shaft 222 can pass through a hole smaller than its own diameter and be locked with the assembly object after passing through the hole, specifically, the first rotating shaft 222, the first through hole 213 and the first rotating shaft hole 242 correspond to each other.
[0058] Specifically, the first rotating shaft 222 of the first bottom plate 22 passes through the first through hole 213 of the base 21 and the first rotating shaft hole 242 of the first support 24, and the first rotating shaft hole 242 is locked / coupled with the first rotating shaft 222, that is, the first rotating shaft 222 cannot easily come out of the first rotating shaft hole 242, thereby fixing the first bottom plate 22 and the first support 24 on the base 21, while the first bottom plate 22 and the first support 24 can rotate around the axis of the first through hole 213.

The diameter of the first gasket 29 is larger than the width of the first guide slot 21a, and the first gasket 29 is limited by the elastic clamping jaw of the first expansion pin 221 and cannot come out. By using the first gasket 29 to limit the first expansion pin 221 from sliding out of the first guide slot 21a between the base 21 and the elastic clamping jaw of the first expansion pin 221, when the first bottom plate 22 rotates around the axis of the first through hole 213 of the base 21, the first expansion pin 221 slides in the first guide slot 21a, and the first gasket 29 provides support for the first bottom plate 22, so that the first bottom plate 22 is not easy to sag / deform downward.
[0060] In addition, the support is also provided with a guide column with a limiting boss, which is slidingly connected in the guide rail, and the limiting boss is clamped outside the guide rail.
[0061] Please refer to Figure 9 , Figure 10 and Figure 11 , the first guide column 244 of the first support 24 is taken as an example, the first guide column 244 of the first support 24 slides into the first sliding rail 21c of the base 21, and the guide rail of the first sliding rail 21c limits the upward movement of the first limiting boss 244a of the first guide column 244; the first guide column 244 is limited from moving upward, and when the first support 24 rotates around the axis of the first through hole 213 of the base 21, the first guide column 244 slides in the first sliding rail 21c, and the first guide column 244 simultaneously makes the first bottom plate 22 not easy to sag / deform downward.
[0062] It should be noted that the first bottom plate 22 and the second bottom plate 23 are mirror image structures, and the second bottom plate 23 is also provided with a second expansion pin, a second rotating shaft and a second hoisting hole. The first support 24 and the second support 25 are mirror image structures, and the second support 25 is consistent with the first support 24 in structure and installation mode, which will not be specifically described here.
[0063] In some preferred embodiments, lubricating grease can be applied in the first guide slot 21a, the second guide slot 21b, the first sliding rail 21c and the second sliding rail 21d, so as to reduce the sliding resistance and noise.
[0064] In addition, in order to facilitate the rotation of the support, a driving mechanism 26 is installed on the base 21, and a motor, a speed reducer, a position sensor, etc. can be arranged inside the driving mechanism 26. The driving mechanism 26 is provided with a wire harness 261 connected with the controller of the vehicle, and the driving mechanism 26 can be adjusted by the controller of the vehicle to adjust the movement state. The deflector 2 further comprises two screw rods, both of which are connected with the driving mechanism. The support is provided with a gear in transmission connection with the screw rod, and the driving mechanism is used to drive the screw rod to rotate so as to drive the support to rotate relative to the base through the gear.
[0065] Specifically, the two screw rods are respectively a first worm 27 and a second worm 28, and the first worm 27 and the second worm 28 are respectively provided with helical grooves / helical teeth.
[0066] Now taking the first worm 27 and the first gear 241 on the first support 24 as an example, the helical grooves / helical teeth of the first worm 27 are in meshing connection with the first gear 241 and are configured as a worm and gear transmission mechanism. The driving mechanism 26 can independently drive the first worm 27 or the second worm 28 to rotate, and the rotation can be forward rotation or reverse rotation.
[0067] Similarly, the second worm 28 and the second gear on the second support 25 are in the same transmission mode as the first worm 27 and the first gear 241 on the first support 24.

[0069] When the driving mechanism 26 drives the first worm 27 to rotate in the first direction, the first worm 27 drives the first support 24 to rotate clockwise around the axis of the first through hole 213 through the first gear 241, and the first support 24 further drives the first bottom plate 22 to rotate clockwise around the axis of the first through hole 213.
[0070] The first bottom plate 22 is partially rotated to the lower side of the base 21, Figure 15 It is shown that the deflector 2 is in a partially folded state. The contracted first bottom plate 22 can avoid interference with the steered wheel 13.

[0073] As shown in Figure 5 , Figure 16 , Figure 17 When the driving mechanism 26 drives the second worm 28 to rotate in the first direction, the second worm 28 drives the second support 25 to rotate anticlockwise around the axis of the second through hole 214 through the corresponding second gear,
[0074] The second support 25 further drives the second bottom plate 23 to rotate anticlockwise around the axis of the second through hole 214. The second bottom plate 23 is partially rotated to the lower side of the base 21, Figure 17 The deflector 2 is shown in the partially folded state. The contracted second bottom plate 23 can avoid interference with the steered wheel 13.
[0075] On the basis of Figure 17 , when the wheel 13 is straightened, the driving mechanism 26 can drive the second worm 28 to rotate in the second direction, the second worm 28 drives the second support 25 to rotate clockwise around the axis of the second through hole 214 through the second gear, and the second support 25 further drives the second bottom plate 23 to rotate clockwise around the axis of the second through hole 214.
[0076] The deflector 2 restores to the fully unfolded state, maximally obstructs the airflow at the bottom, makes the chassis more flat, and further reduces the air resistance and noise.
[0077] As shown in Figure 18 , Figure 19 The movement of the driving mechanism 26 can be linked with the position / state of the steering wheel / steering mechanism. When the driver rotates the steering wheel to drive the wheel 13 to steer, the driving mechanism 26 can adjust the movement of the first bottom plate 22 or the second bottom plate 23 of the first deflector 2a and the second deflector 2b, respectively;
[0078] When the wheel 13 is steered, one end of the wheel 13 moves inward, and the other end moves outward. The first deflector 2a and the second deflector 2b automatically contract the first bottom plate 22 or the second bottom plate 23 on the inward movement side of the wheel 13. The contracted first bottom plate 22 or the second bottom plate 23 can avoid interference with the steered wheel 13.
[0079] The first deflector 2a and the second deflector 2b maintain the fully unfolded state when the vehicle is driving straight, maximally obstruct the airflow at the bottom, make the chassis more flat, and further reduce the air resistance and noise. When the wheel 13 is steered, the first deflector 2a and the second deflector 2b are actively switched to the partially folded state, and the contracted first deflector 2a and the second deflector 2b can avoid interference with the steered wheel 13.
