The invention discloses a multi-degree-of-freedom automobile active aerodynamic suite. The suite comprises a multi-degree-of-freedom driving empennage, a driving diffuser and a driving front lip, wherein the multi-degree-of-freedom driving empennage is fixed on an upper cover of a trunk of a motor automobile, the multi-degree-of-freedom driving empennage comprises an empennage bottom plate, an empennage main plate, an electric push rod and a sliding block, the empennage bottom plate is used for being fixedly connected with an upper cover of a motor automobile trunk, one end of the electric push rod is fixed to the empennage bottom plate, the other end of the electric push rod is hinged to the sliding block, and the sliding block is connected with the empennage main plate. Compared with theprior art, by adding the multi-degree-of-freedom driving empennage, the empennage can perform lifting, overturning and side-tipping conversion according to different automobile speeds and driving modes to meet aerodynamic force requirements in various states, so stability of the automobile in driving is ensured, a wind resistance coefficient of normal driving is reduced, and the curve performancecapability of the automobile in high-speed driving is improved.

    本发明公开了一种多自由度汽车主动空气动力学套件,包括多自由度主动尾翼、主动扩散器以及主动前唇,所述的多自由度主动汽车尾翼固定在机动车后备箱上盖上,多自由度主动汽车尾翼包括尾翼底板、尾翼主板、电推杆以及滑块,所述的尾翼底板用于与机动车后备箱上盖固定连接,所述的电推杆一端与尾翼底板固定,另一端与所述的滑块铰接,所述的滑块与尾翼主板连接。与现有技术相比,通过增加多自由度的主动尾翼,该尾翼可以根据车速和驾驶模式的不同进行升降、翻转以及侧倾变换,来满足各个状态下的空气动力需要,保证了汽车行驶中的稳定性,降低了正常行驶的风阻系数,改良汽车高速行驶下的弯道表现能力。
