The invention relates to the field of electric empennages, and discloses an automobile electric empennage. The device is provided with a mounting box, a support, a deformation wing plate mounted in the mounting box and a deformation mechanism mounted in the support, and the deformation mechanism comprises an extrusion block hinged to the end of the deformation wing plate, a bidirectional lead screw in threaded connection with the extrusion block and a driving motor connected with the bidirectional lead screw through a first worm gear and a worm; the deformation wing plate is bent downwards to extend out of the mounting box by applying extrusion force towards the center to the two ends of the deformation wing plate, flow guiding of airflow is achieved, downward pressure is increased, the bending radian of the deformation wing plate is changed according to the vehicle speed, wide-range adjustment of the downward pressure is achieved, no power element is exposed during adjustment, and adjustment stability is good.

    本发明涉及电动尾翼领域,公开了一种汽车电动尾翼;本发明通过设有安装盒、支座、安装在安装盒内的变形翼板、安装在支座内的变形机构,变形机构包括与变形翼板端部铰接的挤压块、与挤压块螺纹连接的双向丝杆、通过第一蜗轮和蜗杆与双向丝杆连接的驱动电机,通过对变形翼板两端施加向中心的挤压力使得变形翼板向下弯曲伸出安装盒,实现对气流的导流,增加下压力,根据车速改变变形翼板的弯曲弧度,实现下压力的宽范围调节,调节时无外漏动力元件,调节稳定性好。
