The invention belongs to the field of aircraft control surface control, and particularly relates to a cracking type control surface deflection lead screw series drive movement mechanism. Comprising an upper airfoil, a lower airfoil, a ball screw and an upper and lower airfoil connecting rod. A first connecting part is arranged on the upper wing surface; a second connecting part is arranged on the lower wing surface, and the second connecting part is hinged to the first connecting part; a lead screw nut is installed on the ball screw, the ball screw is connected with a first driving mechanism and a second driving mechanism, the first driving mechanism is used for driving the ball screw to deflect up and down, and the second driving mechanism is used for driving the ball screw to rotate around the axis of the ball screw; one end of the upper airfoil connecting rod is connected with the lead screw nut, and the other end is connected with the upper airfoil; and one end of the lower airfoil connecting rod is connected with the screw nut, and the other end is connected with the lower airfoil. The defect that a traditional cracking type control surface driving mode control system is complex is overcome, the control requirement for a flight control system is lowered, and the situation that when the upper wing surface and the lower wing surface deflect by the same angle, mutual interference is generated is also avoided.

    本申请属于飞机舵面控制领域,特别涉及一种开裂式舵面偏转丝杠串联驱动运动机构。包括:上翼面、下翼面、滚珠丝杠、上下翼面连杆。上翼面上设置有第一连接部;下翼面上设置有第二连接部,第二连接部与第一连接部铰接;滚珠丝杠上安装有丝杠螺母,滚珠丝杠分别与第一驱动机构以及第二驱动机构连接,第一驱动机构用于驱动滚珠丝杠上下偏转,第二驱动机构用于驱动滚珠丝杠绕自身轴线旋转;上翼面连杆的一端与丝杠螺母连接,另一端与上翼面连接;下翼面连杆的一端与丝杠螺母连接,另一端与下翼面连接。本申请克服了传统开裂式舵面驱动方式操控系统复杂的弊端,降低了对飞控系统的控制要求,也避免了上下两翼面偏转相同角度时产生互相干涉的情况。
