Description
Technical Field
[0001] The utility model belongs to the technical field of automobile accessories and relates to a spoiler assembly of a new energy vehicle. Background Art
[0002] The car spoiler is a plate-shaped structure at the rear of the car used to guide the flow of air. On the one hand, it can guide the flow direction of the airflow passing through the rear of the car so that the car can be subjected to less resistance. On the other hand, it can increase the pressure of the car on the ground, so that the car tires have sufficient friction resistance with the ground to push the car forward; at the same time, it prevents the car from being blown away by the oncoming airflow when the car is too fast. The adjustment of the height and angle of the spoiler can change the drag and lift performance of the car. The existing mechanism structure for adjusting the height and angle of the spoiler is relatively complex, with many connecting rods. Although the adjustment function is relatively independent, it is not conducive to reducing costs and is not convenient for assembly and disassembly. Utility Model Content
