Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and in particular to an electric rear wing structure for automobiles. Background Technology

[0002] When a car travels at high speed, according to aerodynamic principles, it encounters air resistance. This generates aerodynamic forces in three directions—longitudinal, lateral, and vertical—around the car's center of gravity, with longitudinal force being air resistance. The function of a car's rear wing is to create downward pressure from this air resistance at high speeds, minimizing lift and effectively controlling downforce to reduce the drag coefficient and increase high-speed stability. Because rear wings reduce air resistance, they can also help save fuel on high-speed vehicles. Furthermore, they enhance the car's appearance, serving a decorative purpose.

[0003] To effectively reduce and overcome the effects of air resistance when a car is traveling at high speeds, a rear wing has been designed and used. Its function is to generate a fourth force on the car – a significant force of adhesion to the ground. This force counteracts some of the lift, effectively controlling the car's upward movement, reducing the drag coefficient, and allowing the car to stay firmly on the road surface, thus improving driving stability. Currently, most rear wings on the market are fixed; only a very small number of high-end models have electric rear wings, and their structural designs are quite complex. Summary of the Invention
