The invention discloses a wing multi-degree-of-freedom variant mechanism simulating a bird wing skeleton, and belongs to the technical field of aircraft wing structure design. The robot comprises a robot body, a first rotating arm, a second rotating arm and a third rotating arm which are sequentially connected, wherein the second rotating arm comprises a second rotating arm a and a second rotating arm b; the fuselage is movably connected with the first rotating arm through a ball joint mechanism to realize variant movement of the first rotating arm; the first rotating arm is movably connected with the second rotating arm a; the first rotating arm is movably connected with the second rotating arm b; the sweepback variant activity of the second rotating arm is realized through a third driving module; the second rotating arm a is movably connected with the third rotating arm, and the second rotating arm b is movably connected with the third rotating arm, so that collaborative sweepback movement of the third rotating arm is achieved. The multi-degree-of-freedom morphing wing structure is obtained through simulation of bird wings, change control over the area, the dihedral angle, the sweepback angle and the torsion angle of the wings is achieved, and the maneuvering performance of the bird-imitating unmanned aerial vehicle is further improved.

    一种仿鸟翅膀骨骼的机翼多自由度变体机构,属于飞行器机翼结构设计技术领域。它包括依次连接的机身、第一旋臂、第二旋臂及第三旋臂,第二旋臂包括第二旋臂a及第二旋臂b;所述机身与第一旋臂之间通过球关节机构活动连接实现第一旋臂的变体活动;所述第一旋臂与第二旋臂a、第一旋臂与第二旋臂b之间均活动连接并通过第三驱动模块实现第二旋臂的后掠变体活动;所述第二旋臂a与第三旋臂之间、第二旋臂b第三旋臂之间均活动连接实现第三旋臂的协同后掠运动。本发明通过对鸟类翅膀进行仿真模拟出的多自由度变体机翼结构,实现了对机翼的面积、上反角、后掠角和扭转角的变化控制,对于仿鸟类无人机的机动性能有了进一步的提高。
