The invention provides a downward pressure self-adaptive adjusting device which comprises a motor and flow guide fins, the motor is arranged in an automobile, and the flow guide fins are symmetrically arranged on the two sides of a front bumper or a front fender. The output shaft of the motor is fixedly connected with the flow guide fin and can drive the flow guide fins to rotate telescopically; and when the flow guide fins do not work, the flow guide fins are hidden in the front bumper or the front fender, and when the flow guide fins work, the output shaft drives the flow guide fins to extend out of the front bumper or the front fender and rotate to adjust the angle. The invention further provides a downward pressure self-adaptive adjusting method and an automobile. Due to the fact that the downward pressure self-adaptive adjusting device comprises the flow guide fins, the angles of the flow guide fins can be adjusted in a self-adaptive mode according to needs when the flow guide fins are used so as to effectively increase downward pressure of the automobile front axle, and the flow guide fins are hidden when not used so as to avoid increasing whole automobile wind resistance.

    本发明提供一种下压力自适应调节装置,所述下压力自适应调节装置包括电机和导流鳍,所述电机设置于汽车内部,所述导流鳍对称地设置于前保险杠两侧或前翼子板上,所述电机的输出轴与所述导流鳍固定连接并可带动所述导流鳍伸缩转动;所述导流鳍不工作时所述导流鳍隐藏于所述前保险杠或所述前翼子板中,所述导流鳍工作时所述输出轴带动所述导流鳍伸出所述前保险杠或所述前翼子板外并转动以调整角度。本发明还提供一种下压力自适应调节方法、以及一种汽车。上述下压力自适应调节装置,由于包括导流鳍,导流鳍使用时可根据需要自适应调节角度以有效增加汽车前轴下压力,导流鳍不使用时隐藏以避免增加整车风阻。
