The invention belongs to the technical field of flappingwing aircrafts and in particular to a variable-area flapping wing driving mechanism which comprises a swing rod driving mechanism, a left wing and a right wing, wherein the structures of the left wing and the right wing are the same; the left wing and the right wing are umbrella-shaped; the left wing and the right wing are arranged at the output end of the swing rod driving mechanism in a bilateral symmetry mode; the swing rod driving mechanism is used for driving the left wing and the right wing to swing up and down synchronously; when the swing rod driving mechanism drives the left wing and the right wing to beat downwards, the left wing and the right wing are gradually unfolded, the area of the left wing and the area of the right wing are increased, and when the swing rod driving mechanism drives the left wing and the right wing to lift upwards, the left wing and the right wing are gradually folded, and the area of the left wing and the area of the right wing are decreased. The variable-area flapping wing driving mechanism has the beneficial effects that compared with an existing flapping wing driving mechanism, the variable-area flapping wing driving mechanism has the advantages that the structure is simple and easy to implement, buoyancy is improved, resistance is reduced, and high lift force and pushing force are increased.
本发明属于扑翼飞行器技术领域,尤其涉及一种变面积扑翼驱动机构,包括摆杆驱动机构、左翅膀和右翅膀,所述左翅膀和右翅膀的结构相同,所述左翅膀和右翅膀均呈伞状,所述左翅膀和右翅膀呈左右对称设置在摆杆驱动机构的输出端,所述摆杆驱动机构用于驱动左翅膀和右翅膀同步上下摆动;当所述摆杆驱动机构驱动左翅膀和右翅膀下拍时,所述左翅膀和右翅膀均逐渐展开、面积变大,当所述摆杆驱动机构驱动左翅膀和右翅膀上扬时,所述左翅膀和右翅膀均逐渐收拢、面积变小。有益效果:本发明的一种变面积扑翼驱动机构,与现有的扑翼驱动机构相比,具有结构简单易行、提高浮力、降低阻力、增大高升力和推动力的优点。
