The invention relates to the technical field of new energy automobiles, in particular to an automobile active diffuser which comprises a rear bumper, a spoiler body and a main frame, switch push rods are installed on the positions, close to the two sides, of the surface of the upper end of the spoiler body, and a first positioning frame and a second positioning frame are fixedly installed on the positions, close to the two ends, of the outer side wall of the main frame correspondingly; a first pre-hanging frame and a second pre-hanging frame are fixedly installed on the outer side wall of the main frame and located between the first positioning frame and the second positioning frame, four spoiler fixing frames are fixedly installed on the side, away from the first positioning frame, of the main frame, and an actuator is fixedly installed on the outer side wall, close to the middle, of the main frame. Different angles of the spoiler can be changed, downward pressure is increased when the downward pressure is needed, air resistance is reduced when the downward pressure is not needed, two sets of switch push rods are connected with the spoiler body through shaft pins, a four-connecting-rod structure is formed, power is effectively increased, and power output is reduced.

    本发明涉及新能源汽车技术领域,尤其涉及一种汽车主动式扩散器,包括后保、扰流板主体与主框架,所述扰流板主体上端表面靠近两侧位置均安装有开关推杆,所述主框架外侧壁靠近两端位置分别固定安装有定位框一与定位框二,所述主框架外侧壁且位于定位框一与定位框二之间位置固定安装有预挂框一与预挂框二,所述主框架远离定位框一一侧固定安装有四个扰流板固定框,所述主框架外侧壁靠近中间位置固定安装有执行器。本发明可以改变扰流板的不同角度,在需要下压力时增大下压力,在不需要下压力时减小空气阻力,且通过设置两组开关推杆均与扰流板主体轴销连接,形成一个四连杆结构,有效增大动力,减少动力输出问题。
