The invention discloses a wing variable sweepback mechanism which comprises a worm and gear assembly and two planar connecting rod assemblies, and the planar connecting rod assemblies are symmetrically distributed relative to the worm and gear assembly. The motor provides driving torque, the motor shaft transmits the driving torque to the worm, and the worm is meshed with the worm gear and can drive the worm gear to rotate around the shaft. The worm gear is fixedly connected with the rod I, namely the worm gear can drive the rod I to synchronously rotate around a worm gear shaft; the first rod, the second rod and the third rod form a plane connecting rod assembly, the first rod is a driving rod, the second rod is a linkage rod, the third rod is a driven rod, the first rod and the third rod are each provided with a hinge support, and the first rod and the third rod are connected through a connecting line to form a fixing rod. And the third rod is fixedly connected with the deformation wing, namely, the third rod can drive the deformation wing to rotate around a hinge fulcrum on the deformation wing, so that the wing can be swept back.

    本发明公开一种机翼变后掠机构,包括蜗轮蜗杆组件和平面连杆组件,其中平面连杆组件设置两组,相对于蜗轮蜗杆组件对称分布。电机提供驱动力矩,电机轴将驱动力矩传至蜗杆,蜗杆与蜗轮啮合,可带动蜗轮绕轴转动;蜗轮与杆一固接,即蜗轮可带动杆一绕蜗轮轴同步转动;杆一、杆二和杆三组成平面连杆组件,其中杆一为主动杆、杆二为连动杆,杆三为从动杆,杆一、杆三上分别设置一铰支,二者连线构成固定杆;杆三与变形翼固接,即杆三可带动变形翼绕其上的铰支点转动,从而可以实现机翼变后掠。
