Description

Technical Field

[0001] The utility model relates to the technical field of automobile components, in particular to an aerodynamic downforce component. Background Art

[0002] Airflow regulators are a common aerodynamic downforce component. They are usually designed to adjust the direction, speed or flow path of the airflow in the gas flow to achieve a specific purpose, such as reducing drag, improving stability or increasing efficiency. Airflow regulators can achieve a pressure reduction effect by introducing additional resistance in the fluid or changing the direction of the flow, thereby producing the desired effect in aerodynamics. Common airflow regulators include spoilers, rear wings, aerodynamic edges, etc. Spoilers are usually installed at the rear of the vehicle, such as the trunk lid or the rear of the car. This position can help reduce the lift of the tail and improve the stability and traction of the vehicle. Nowadays, convex wings are arranged on common spoilers. Convex wings play an important role on spoilers and can increase aerodynamic performance, such as improving traction and stability.

[0003] However, the convex wings provided on the existing spoilers are usually fixed in an integrated manner. As they are relatively fragile as a whole, they are prone to softening after being exposed to the sun for a long time, which increases the risk of damage and makes them difficult to replace after damage. In view of this, we propose an aerodynamic downforce component. Utility Model Content

[0012] Compared with the prior art, the utility model has the following beneficial technical effects:

[0013] The utility model starts the electric telescopic rod to drive the movable plate to move, so that the movable plate drives the positioning component to move, thereby achieving adjustment of the height of the convex wing, which is beneficial to controlling the exposed size of the convex wing according to the driving environment and driving conditions, and improving the driving stability of the vehicle. Due to the setting of the positioning component, the movable plate in the moving state is guided to avoid the position shift of the convex wing during the activity, which affects the subsequent storage. At the same time, under the drive of the electric telescopic rod, the convex wing can be stored into the spoiler body for protection, avoiding exposure to the outside when the vehicle is not driving, thereby increasing the risk of damage.
