The invention provides an active translation type rear diffuser device of an automobile. The active translation type rear diffuser device comprises an arc-shaped diffuser body and a driving mechanism,wherein the arc-shaped diffuser body is mounted below a bumper on the tail of the automobile and arranged in bilateral symmetry along the center line of an axle, and the driving mechanism controls the arc-shaped diffuser body to move. Vehicle speed signals are obtained through a vehicle speed sensor additionally arranged on the automobile and transmitted to an ECU to be subjected to data analysisand judgment, and the driving mechanism moves to control movement of the arc-shaped diffuser body, the arc-shaped diffuser body slides out backwards only under the high-speed running condition of theautomobile, and the basic pressure of the automobile is increased, therefore, low-pressure air is prevented from directly flowing to the rear surface of a trunk from the bottom of the automobile, andmeanwhile, the diffusion process is generated, the speed is reduced, the pressure of airflow at the bottom of the automobile is increased, aerodynamic drag reduction is achieved, overall oil consumption of the automobile is reduced, and good application value is achieved.

    本发明提出了一种汽车主动平移式后扩散器装置,包括汽车的车尾安装在保险杠下方沿着车轴中心线左右对称布置的弧形扩散器本体、控制弧形扩散器本体移动的驱动机构;通过加装在汽车上的车速传感器获取车速信号传递给ECU控制单元进行数据分析判断,驱动机构运动来控制弧形扩散器本体的移动,弧形扩散器本体仅在汽车高速行驶条件下向后滑出,增加汽车的基础压力,从而防止低压空气从车底直接窜到行李箱的后表面,同时产生扩散过程,降低速度,增加车底气流的压力,从而实现空气动力学减阻,降低汽车整体油耗,具有较好的应用价值。
