The invention relates to the technical field of automobile parts, in particular to a commercial vehicle spoiler moving mechanism capable of regulating and controlling resistance reduction, which comprises a side spoiler, an upper spoiler, an electric push rod, a four-bar mechanism and an electric control device, and is characterized in that the running speed of an automobile is measured through a commercial vehicle sensor, and the commercial vehicle spoiler is unfolded when a certain speed is reached; the electric push rods of the side empennages are driven to be completely unfolded, and then the electric push rods of the upper empennages are driven to be completely unfolded; when the speed of the commercial vehicle is reduced to a certain speed, the tail wing of the commercial vehicle is folded, namely the electric push rod of the upper tail wing is driven to be completely folded firstly, and then the electric push rod of the side tail wing is driven to be completely folded, so that the problems that the wind resistance coefficient of the commercial vehicle is high due to overlarge eddy current generated at the tail of a compartment when the commercial vehicle without the tail wing runs at a high speed; and a commercial vehicle with an empennage is large in infiltration area when running at a low speed, so that the wind resistance coefficient of the commercial vehicle is high, and the fuel economy is poor.

    本发明涉及汽车零部件技术领域,尤其涉及一种可调控减阻的商用车尾翼活动机构,包括侧尾翼、上尾翼、电动推杆、四杆机构和电控装置,通过商用车传感器测量汽车行驶速度,达到一定速度时展开商用车尾翼,即先驱动侧尾翼的电动推杆完全展开、后驱动上尾翼的电动推杆完全展开;在商用车速度降至一定速度时收起商用车尾翼,即先驱动上尾翼的电动推杆完全收起、后驱动侧尾翼的电动推杆完全收起,从而解决无尾翼的商用车高速行驶时车厢尾部产生的涡流过大使得商用车的风阻系数高,而有尾翼的商用车低速行驶时的浸润面积较大使得商用车风阻系数高,燃油经济性不好的问题。
