Automobile tail turbulence protection structure

Abstract

The invention discloses an automobile tail turbulence protection structure. The automobile tail turbulence protection structure comprises two tail wing structures, two lifting channels and a hydraulic pipeline. The tail wing structures are located in the lifting channels. Each tail wing structure comprises a main wing, an auxiliary wing parallel with the main wing and a driving mechanism, wherein the main wing is located below the auxiliary wing, the front end of the auxiliary wing is close to the tail end of the main wing, end plates are arranged at the same-side ends of the main wing and the auxiliary wing respectively, a rotating plate is arranged on the main wing, the main wing is fixedly connected with the end plates, the auxiliary wing is connected with the end plates in a rotating mode, and the driving mechanism comprises a main wing cylinder, an auxiliary wing cylinder and a base provided with a rotating auxiliary cylinder. The hydraulic pipeline comprises a hydraulic pump, a main wing pipeline used for opening or closing the two main wing cylinders at the same time, an auxiliary wing pipeline and a rotating auxiliary pipeline used for opening or closing the rotating auxiliary cylinders independently. Strip-shaped through holes are formed in the positions, above the auxiliary wings, of the front sides of the end plates. The automobile tail turbulence protection structure can adjust the downward pressure and air resistance of the left and right sides of the tail of an automobile, so that the road holding of the automobile is improved, and loads on tires are reduced.

Description

technical field [0001] The invention belongs to the field of automobiles, in particular to a rear spoiler protection structure. Background technique [0002] During the driving process of the car, due to the shape and structure characteristics of the car itself, the car will generate an upward lift when driving, and the adhesion between the car and the ground will decrease. When the car is running at a high speed, this phenomenon is more prominent. In order to alleviate the negative impact of lift on the driving stability of the car as much as possible, designers often start from the shape of the car and optimize the shape of the car to reduce the lift generated. In addition, on high-performance cars, sports cars or racing cars, in order to improve the adhesion of the car to the ground when cornering, a front wing or tail will be installed on the head or tail of the car. The cross-sectional shape of the wing is similar, but its installation method is just opposite to that o...

Problems solved by technology

[0003] In the actual driving process, especially in the case of high-speed curves, the car will have a tendency to roll to the outside of the curve due to the centrifugal effect, and the positive pressure on the tires located on the inside of the curve is reduced, while the tires on the outside of the curve The positive pressure on the tires increases, and the car has a large roll, which will easily cause the car to break through the adhesion limit of the outer wheel of the curve and slip.

However, since the front and rear wings exert the same downforce on the left and right sides of the car, it is still difficult to alleviate this situation
