An air pressure chamber is fixedly connected to the top of the air delivery pipe. Air pressure rods are slidably connected to the two bottom sides of the air pressure chamber. A downward pressing plate is fixedly connected to the bottom of the air pressure rods. A limiting groove is arranged below the downward pressing plate.

[0008] Further, the shape of the fairing main body is set as an arc. The material of the fairing main body is alloy steel, and the fairing main body can effectively reduce wind resistance and fuel consumption.

[0009] Further, the airbag is fixedly connected to the bottom of the fairing main body. The air pressure chamber is fixedly connected to the inside of the fairing main body. The air pressure chamber is fixedly connected in the connecting groove. The shape of the air pressure chamber is set as a T shape. After being squeezed, the airbag can effectively transport the internal gas to the inside of the air pressure chamber through the air delivery pipe.

[0010] Further, the material of the downward pressing plate is metal steel. The limiting groove is opened at the lower end inside the fairing main body. The downward pressing plate will drive the fairing main body to provide downward pressure.

[0011] Further, the center of gravity adjusting device includes a connecting rod, a counterweight is fixedly connected to the side of the connecting rod, a rotating rod is rotatably and penetratingly connected inside the counterweight, speed reducing wheels are fixedly connected to both sides of the rotating rod, a fixing groove is arranged below the counterweight, and the center of gravity adjusting device can effectively adjust the center of gravity of the main body of the fairing.

[0012] Further, one side of the connecting rod away from the counterweight is fixedly sleeved on the outside of the pneumatic rod, and the counterweight is made of metal steel, and the connecting rod will drive the counterweight to move.

[0013] Further, the side of the speed reducing wheel is attached to the inner wall of the main body of the fairing, the speed reducing wheel is made of rubber with strong friction, and the fixing groove is opened at the lower end inside the main body of the fairing.

[0014] The utility model has the following beneficial effects:

[0015] 1. Through the pressing device of the utility model, when the vehicle is running at a high speed, the main body of the fairing can be initially pressed down by wind resistance. While the main body of the fairing is being pressed down, the airbag will be squeezed, and the airbag will transport the internal gas to the inside of the pneumatic chamber through the air delivery pipe. The pneumatic chamber will drive the pneumatic rod and the lower pressing plate to move, so that the main body of the fairing can provide a downward pressure and increase the driving stability of the vehicle, and the practicability is relatively strong.

[0016] 2. Through the center of gravity adjusting device of the utility model, the connecting rod and the counterweight can be driven to move while the pneumatic rod is moving. The speed reducing wheel can effectively prevent the descending speed of the counterweight from being too fast and causing damage to the main body of the fairing.

[0028] The pressing-down device 5 includes an airbag 51, an air delivery pipe 52 is fixedly connected to the top of the airbag 51, a pressure chamber 53 is fixedly connected to the top of the air delivery pipe 52, pressure rods 54 are slidably connected to the bottom sides of the pressure chamber 53, a lower pressing plate 55 is fixedly connected to the bottom of the pressure rods 54, and a limiting groove 56 is provided below the lower pressing plate 55.

[0029] The shape of the main body 1 of the fairing is set to be arc-shaped, the material of the main body 1 of the fairing is alloy steel, and the main body 1 of the fairing can effectively reduce wind resistance and fuel consumption.

[0030] The airbag 51 is fixedly connected to the bottom of the fairing body 1, the air pressure chamber 53 is fixedly connected inside the fairing body 1, the air pressure chamber 53 is fixedly connected in the connecting groove 2, the shape of the air pressure chamber 53 is set to be T-shaped, and after being squeezed, the airbag 51 can effectively transport the internal gas to the inside of the air pressure chamber 53 through the air pipe 52.

[0031] The material of the lower pressing plate 55 is metal steel, and the limiting groove 56 is opened at the lower end inside the fairing body 1. The lower pressing plate 55 will drive the fairing body 1 to provide a downward pressure.

[0032] The center-of-gravity adjusting device 6 includes a connecting rod 61, a counterweight 62 is fixedly connected to the side of the connecting rod 61, a rotating rod 63 is rotatably connected through the counterweight 62, reduction wheels 64 are fixedly connected to both sides of the rotating rod 63, a fixing groove 65 is arranged below the counterweight 62, and the center-of-gravity adjusting device 6 can effectively adjust the center of gravity of the fairing body 1.

[0033] One side of the connecting rod 61 away from the counterweight 62 is fixedly sleeved on the outside of the air pressure rod 54. The material of the counterweight 62 is metal steel, and the connecting rod 61 will drive the counterweight 62 to move.

[0034] The side of the reduction wheel 64 is attached to the inner wall of the fairing body 1. The material of the reduction wheel 64 is rubber with strong friction. The fixing groove 65 is opened at the lower end inside the fairing body 1. The reduction wheel 64 will slide and rub against the inner wall of the fairing body 1 to generate resistance and slow down the descending speed of the counterweight 62.

[0035] Through the pressing device 5 of the present utility model, when the vehicle is driving at a high speed, the fairing body 1 can be initially pressed down by wind resistance. While the fairing body 1 is being pressed down, the airbag 51 will be squeezed, and the airbag 51 will transport the internal gas to the inside of the air pressure chamber 53 through the air pipe 52. The air pressure chamber 53 will drive the air pressure rod 54 and the lower pressing plate 55 to move, so that the fairing body 1 can provide a downward pressure, increasing the driving stability of the vehicle, and the practicability is relatively strong.

[0036] A specific application of this embodiment is as follows: When the vehicle is traveling at a high speed, the wind resistance causes the main fairing body 1 to be initially pressed downwards. When the main fairing body 1 is initially pressed downwards, the airbag 51 is squeezed. The airbag 51 will transport the gas inside to the inside of the pneumatic chamber 53 through the air delivery pipe 52. The pneumatic chamber 53 will drive the pneumatic rod 54 and the lower pressing plate 55 to move, causing the main fairing body 1 to be pressed downwards for the second time, which can reduce the wind resistance, effectively save fuel, and enhance the driving stability of the vehicle. When the wind resistance is relatively low, the elastic support rod 3 and the torsion spring rod 4 will drive the main fairing body 1 to return to its original position. The airbag 51 will no longer be squeezed. The gas inside the pneumatic chamber 53 will flow back to the inside of the airbag 51 through the air delivery pipe 52, and the airbag 51 will return to its inflated state again. The pneumatic rod 54 and the lower pressing plate 55 will return to their original positions without the drive of gas, which is convenient for the next use, and the practicability is relatively strong. While the pneumatic rod 54 is moving, it will drive the connecting rod 61, the counterweight 62, and the reduction wheel 64 to move. The reduction wheel 64 can effectively prevent the counterweight 62 from descending too fast and damaging the main fairing body 1. After the counterweight 62 descends to a fixed position, it can effectively change the center of gravity of the main fairing body 1, and cooperate with the pressing device 5 to strengthen the pressing effect of the main fairing body 1, further enhancing the practicability of the entire device.
