The invention is applicable to the technical field of automobiles, and provides a passenger car active rear diffuser device which comprises a diffuser support, a translation part is slidably mounted at the bottom of the diffuser support, and a translation driving mechanism used for driving the translation part to slide along the bottom of the diffuser support is arranged on the diffuser support. A translation part is arranged on the base, the movement stroke of the translation part is 130 mm, a rotating part is hinged to the translation part through a hinge, an electric push rod used for adjusting the rotating angle of the rotating part is arranged on the translation part, and the electric push rod can drive the rotating part to rotate by 8.5 degrees along the axis of the hinge. The device is driven by a motor and an electric push rod, can be automatically started or manually started by a driver during high-speed driving and can be automatically retracted when the vehicle speed is reduced, the wind resistance coefficient of the vehicle is remarkably reduced during starting, oil consumption of the vehicle is reduced, the original overall size of the vehicle body can be kept during closing, the trafficability is improved, and the original modeling line attractiveness of the vehicle is kept.
本发明适用于汽车技术领域,提供了一种乘用车主动后扩散器装置,包括扩散器支架,所述扩散器支架的底部滑动安装有平动部,且所述扩散器支架上设置有用于驱动平动部沿着扩散器支架的底部进行滑动的平移驱动机构,且所述平动部的运动行程为130mm,所述平动部上通过铰链铰接有转动部,且所述平动部上设置有用于调节转动部的转动角度的电动推杆,且所述电动推杆可带动转动部沿铰链的轴线转动8.5°。该装置由电机以及电动推杆驱动,在高速行驶时可自动开启或由驾驶员手动开启,车速降低时可自动收回,开启时将显著降低车辆的风阻系数,为车辆降低油耗,关闭时可保持车身原有的整体尺寸,提高通过性,保持车辆原有造型线条美观。
