The invention discloses an automobile pneumatic spoiler device which comprises a vehicle body and spoilers, the two spoilers are arranged on a roof of the vehicle body in parallel, the upper end faces of the spoilers are flush with a roof skin of the vehicle body, and the spoilers can be lifted, are higher than the roof skin and rotate. When the automobile accelerates to run, the pneumatic turbulent flow device can play a role of a vortex generator, and air resistance borne by the automobile in the running process is reduced. When the automobile is braked emergently, the pneumatic turbulent flow device can achieve the effects of increasing the windward area and damaging the streamline structure of the automobile, the air resistance in the process is increased, the braking distance is reduced, and the safety of a driver and passengers is guaranteed.
本发明公开了一种汽车气动扰流装置,包括车辆本体和扰流板,两个扰流板相互平行的设置在车辆本体的车顶上,且扰流板的上端面与车辆本体的车顶蒙皮相齐平,扰流板可升起并高出车顶蒙皮并进行转动。本发明提出的气动扰流装置在汽车加速行驶时,能起到涡发生器的作用,降低行驶过程中汽车受到的空气阻力。本发明提出的气动扰流装置在汽车紧急制动时,能起到增大迎风面积,破坏汽车流线型结构的作用,增加在此过程中受到的空气阻力,减少制动距离,保障驾驶员与乘客的安全。
