Description

Rear spoiler with power generation function The present invention relates to a rear spoiler mounted on the rear of a vehicle to improve the aerodynamic performance of the vehicle during high-speed driving, and more specifically, to a rear spoiler having a solar power generation function and a wind power generation function. Generally, a rear spoiler on a car is intended to increase downforce and improve stability by controlling airflow at the rear, thereby allowing the vehicle to grip the road surface better during high-speed driving, increasing cornering stability, and reducing shaking during straight-line driving. In other words, a rear spoiler directs airflow toward the rear of the vehicle to reduce turbulence behind it and pushes the air downward, thereby increasing downforce at the rear of the vehicle. Increased downforce raises tire grip, allowing the vehicle to firmly grip the road, which plays a crucial role in stability during high-speed driving. Additionally, air resistance (drag) occurs when a vehicle travels at high speeds; the spoiler helps to regulate airflow to reduce drag and further contributes to improving fuel efficiency. The "Rear spoiler system and rear spoiler driving method using a solar tracking sensor" (hereinafter referred to as "Patent Document 1") disclosed in the Korean Intellectual Property Office Publication No. 10-2012-0134637 comprises a rear spoiler installed on a vehicle body to control airflow, wherein the operating angle is adjusted according to the speed of the vehicle when the vehicle is driving and the operating direction is adjusted to be perpendicular to sunlight when the vehicle is stopped, and a solar panel provided on the upper side of the rear spoiler body to supply power for adjusting the operating angle and operating direction of the rear spoiler body, and the rear spoiler body is controlled in real time by receiving a vehicle speed signal and a solar measurement signal.
