The invention provides an embedded resistance rudder movement mechanism of an unmanned aerial vehicle and a wing, and belongs to the technical field of unmanned aerial vehicles, the resistance rudder movement mechanism comprises a driving steering engine, an upper connecting rod and a lower connecting rod, the driving steering engine comprises a fixed end and a telescopic end, and the fixed end is used for being hinged to a front beam of the wing; one end of the upper connecting rod is hinged with the telescopic end, and the other end is hinged with the lower surface of the resistance rudder; one end of the lower connecting rod is hinged to the telescopic end, and the other end is hinged to a lower skin of the wing. The resistance rudder movement mechanism can drive the resistance rudder to be opened and closed through stretching and retracting of the driving steering engine, dead points cannot be encountered in the driving process, smooth rotation of the resistance rudder can be guaranteed, after the resistance rudder is closed, the upper connecting rod and the lower connecting rod can be folded to be completely embedded into the wing box, and a fairing does not need to be additionally arranged. Under the condition of large-angle unfolding of the control surface, the equivalent force arm for driving the steering engine is large, the output force of the steering engine can be effectively reduced, and the size of the steering engine is reduced.
本发明提供一种无人机内嵌式阻力舵运动机构及机翼,属于无人机技术领域,阻力舵运动机构包括:驱动舵机、上连杆和下连杆,驱动舵机包括固定端和伸缩端,固定端用于与机翼的前梁铰接;上连杆的一端与伸缩端铰接,上连杆的另一端与阻力舵的下表面铰接;下连杆的一端与伸缩端铰接,下连杆的另一端与机翼的下蒙皮铰接。该阻力舵运动机构能够通过驱动舵机的伸缩带动阻力舵开合,驱动过程中不会遇到死点,可以保证阻力舵顺利转动,阻力舵闭合后上连杆和下连杆能够折叠以完全嵌入翼盒,不需要增设整流罩。在舵面大角度展开的情况下,驱动舵机的等效力臂大,能有效降低舵机输出力,减小舵机体积。
