TECHNICAL FIELD
[0001] The present application relates to the technical field of automobile accessories, and particularly relates to a lightweight and conveniently-installed automobile spoiler assembly. BACKGROUND
[0002] The automobile spoiler is an important component of the aerodynamic kit, and its role is not limited to appearance decoration, but also plays a key role in driving performance and safety. The spoiler guides airflow through special streamline design when the vehicle is running at high speed, generates vertical downward pressure, and increases the friction between the tire and the ground. When the vehicle is running at high speed, the airflow flowing through the roof is easy to form a low-pressure area at the tail, generating upward lift to cause "floating". The spoiler can offset part of the lift by deflecting the airflow, so that the vehicle body is close to the road surface, reducing the interference of crosswind and improving the driving stability. The spoiler can reduce the wind resistance coefficient by combing the airflow at the tail, so that the vehicle responds more stably when changing lanes and overtaking, and reduces the risk of tire skidding. Some existing automobile spoilers are made of metal or plastic. The use of metal material will result in a heavy spoiler, which cannot meet the lightweight demand of new energy vehicles. The heavy weight of the spoiler may also cause the deformation of the automobile trunk lid assembly. The use of plastic material has poor strength and pressure resistance, is easy to change, and is easy to age. Therefore, a lightweight and conveniently-installed automobile spoiler assembly needs to be invented. SUMMARY
