Therefore, when the vehicle runs faster, the second lip plate can extend out relative to the first lip plate, so that the size of the whole front lip structure in the front-rear direction of the vehicle body is enlarged, the front lip structure can receive carding air flow in advance, the stability of the air flow on the surface of the front lip structure is improved, the air flow separation is reduced, the energy loss is reduced, the resistance of the vehicle in the running process is reduced, and the stability of the vehicle in the running process is improved; in addition, when the size of the front lip structure in the front-rear direction of the vehicle body is increased, the high-speed airflow can directly exert force on the front lip structure, so that the downward pressure of the front part of the vehicle can be increased, the accident that the vehicle turns backwards in the running process is avoided, and the stability of the vehicle in the running process is improved; when the front lip structure is larger in the front-rear direction of the vehicle body, air flow at the front part of the vehicle can be shoveled into the upper part by the front lip structure, so that the air flow at the bottom of the vehicle is reduced, namely, the air flow of the chassis of the vehicle is relatively less, so that the energy loss of the air flow is less, and the noise of the chassis is relatively less; in addition, when the vehicle is at a lower speed, the second lip can retract so that the vehicle can maintain a higher throughput.

The foregoing is merely illustrative of the present utility model, and the present utility model is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present utility model. Therefore, the protection scope of the utility model is subject to the protection scope of the claims.
