Description

Technical Field

[0001] The utility model relates to the technical field of automobile tail wings, in particular to an automobile tail wing. Background Art

[0002] A car spoiler is a protrusion that is installed at the rear end of the car's trunk lid and is shaped like a duck's tail. It is part of the car's aerodynamic kit. The main function of a car spoiler is to reduce the lift at the rear of the vehicle and improve the stability of the car. The design principle of a car spoiler is based on aerodynamics. By changing the airflow characteristics at the rear of the vehicle, it can reduce wind resistance, increase downforce and improve stability. When driving at high speeds, the spoiler can change the direction and speed of the airflow at the rear, generate a downward airflow, increase the aerodynamic pressure at the rear of the vehicle, and thus improve the downforce and stability of the vehicle. Some existing car spoilers are difficult to adjust during driving or have a small adjustment angle, resulting in limited effects and difficulty in meeting the needs of users. Utility Model Content
