The invention is suitable for the technical field of automobile spoilers, and provides an automobile active rear spoiler device which comprises a main body frame, an extension part and a rotating part are arranged at the tail of the main body frame, and the extension part is installed at the tail of the main body frame in a sliding mode. A first driving mechanism for driving the extension part to linearly move is arranged in the main body frame, the rotating part is arranged above the extension part, and a second driving mechanism for driving the rotating part to rotate is arranged in the main body frame. The device has two movement modes which do not interfere with each other, and the functions of reducing resistance and improving down force are realized separately, so that the active rear spoiler not only has two main functions of reducing resistance and improving down force, but also maximizes the pneumatic effect of each function, and different mechanisms can be selected for expansion under different working conditions.

    本发明适用于汽车扰流板技术领域,提供了一种汽车主动后扰流板装置,包括主体框架,所述主体框架的尾部设置有伸长部和旋转部,所述伸长部滑动安装于主体框架的尾部,且所述主体框架中设置有用于带动伸长部进行线性移动的第一驱动机构,所述旋转部设置于伸长部的上方,且所述主体框架中设置有用于带动旋转部进行转动的第二驱动机构。该装置具有两种运动方式,且互不干涉,将减阻与提高下压力的功能分开实现,从而使主动后扰流板不仅有减阻和提高下压力两种主要功能,且使每种功能的气动效果最大化,能够在不同的工况下选择不同的机构进行展开。
