Description

Technical Field

[0001] The utility model relates to the technical field of automobile tail wings, and more specifically to a hinge structure of an automobile spoiler. Background Art

[0002] The vehicle is affected by air resistance during driving. At the same time, due to the convex upper and flat lower shape of the car itself, there is a flow velocity difference and pressure difference between the top and bottom of the car, which causes the car to obtain an uplift force during driving. This uplift force can easily affect the driving stability of the vehicle. To solve the above problems, R&D personnel designed a fixed spoiler and installed it at the rear of the car, so that the air can adhere to the ground, thereby offsetting part of the aerodynamic lift and increasing the stability of the car during driving.

[0003] However, the existing fixed spoiler always maintains a fixed extended position and cannot adapt to the usage requirements under different vehicle speeds, resulting in excessive fuel consumption under certain driving conditions. Therefore, the researchers designed an electric lifting spoiler based on this.

[0004] At present, some existing electric lifting spoilers can only realize the function of opening or closing. During the use process, they cannot be accurately stopped at a certain position, which may easily cause deviation in the opening angle of the spoiler and lead to poor stability. Therefore, for the existing electric lifting spoiler, it is necessary to further optimize the aerodynamic characteristics of the vehicle and design a structure with an auxiliary stop position, which can serve as the stop position of the spoiler after opening or retracting, so as to better adapt to the use needs of different cars. Utility Model Content
