The invention provides an unmanned aerial vehicle wing variable-span variable-sweepback mechanism, and belongs to the technical field of deformable wing unmanned aerial vehicle structures. The aircraft comprises a sweepback-variable synchronous lead screw mechanism, two extension-length-variable lead screw driving mechanisms, a sweepback-variable inner side wing and a sweepback-variable extension-length-variable outer side wing, and the outer side wing can be contracted in the inner side wing. A double-head motor in the variable sweepback synchronous lead screw mechanism drives a hinge to rotate through forward and reverse rotation, and variable sweepback of the wings is achieved. The variable-span lead screw driving mechanism drives the outer side wings to extend out of or retract into the inner side wings through forward and reverse rotation of a motor, and the span of the wings is changed. The variable-span mechanism and the variable-sweepback mechanism can change the layout mode ofthe wings according to different flight states so as to fly with high aerodynamic efficiency. The flexible application of the wing variable-span variable-sweepback mechanism of the unmanned aerial vehicle can improve the adaptability of the unmanned aerial vehicle to different flight states.

    本发明提供一种无人机机翼变展长变后掠机构:属于变形翼无人飞行器结构技术领域;包括变后掠同步丝杠机构、两副变展长丝杠驱动机构、变后掠内侧机翼和变后掠变展长外侧机翼,外侧机翼可收缩于内侧机翼中。所述变后掠同步丝杠机构中的双头电机通过正反转驱动铰链转动,实现机翼的变后掠;所述变展长丝杠驱动机构,通过电机正反转驱动外侧机翼伸出或收缩于内侧机翼,改变机翼展长。变展长机构和变后掠机构能够根据飞行状态的不同改变机翼的布局方式,以较高气动效率飞行。无人机机翼变展长变后掠机构的灵活运用可以提高无人飞行器对不同飞行状态的适应能力。
