The invention discloses an active turbulent flow device for an automobile rear bumper and a working method.The device comprises a first air bag and a second air bag, and the first air bag and the second air bag are installed at the two ends of the automobile rear bumper through a first air bag base and a second air bag base correspondingly; the first air bag base and the second air bag base are connected with an air pump through air pipes, the air pump inflates and exhausts the first air bag and the second air bag, the state that the air bags stretch out of the rear bumper is changed, the outer end face of the first air bag and the outer end face of the second air bag are each provided with a rear bumper outer turbulent flow cover plate, and in the air exhausting state, the rear bumper outer turbulent flow cover plate covers the first air bag and the second air bag. The rear bumper outer turbulent flow cover plate is flush with the surface of the automobile body. The air pump can be automatically controlled to be in different working states through vehicle speed information input, and then the air bag is inflated or deflated, so that the form of the active turbulent flow device is changed, and the active turbulent flow device can be selected to be opened or closed according to the vehicle speed.
本发明公开了一种用于汽车后保险杠的主动扰流装置及工作方法,装置包括第一气囊和第二气囊,所述第一气囊和第二气囊分别通过第一气囊底座和第二气囊底座安装在汽车后保险杠的两端,所述第一气囊底座和第二气囊底座通过气管与气泵相连,所述气泵对第一气囊和第二气囊进行充气和抽气,改变气囊从后保险杠上伸出的状态,第一气囊和第二气囊的外端面上均设置有后保外扰流盖板,在抽气状态下,所述后保外扰流盖板与车身表面平齐;本发明可以通过车速信息输入,自动控制气泵处于不同的工作状态,进而使气囊充气或者抽气,从而改变主动扰流装置的形态,可以根据车速选择主动扰流装置的开启或关闭。
