The invention relates to a miniature flapping-wing aircraft with an adjustable wing swing angle, which belongs to the field of miniature bionic aircrafts and comprises a frame part, a transmission device, a flapping device and an adjusting device. The rack part comprises a fuselage, a head, an empennage and a counterweight balance block, and the head and the empennage are fixedly connected with the fuselage; the transmission device comprises a motor, a reduction gear set and a transmission gear. Two large gears are meshed with each other to achieve synchronous and symmetrical movement of wings on the two sides. The flapping device comprises a crank, a rack and wings, one end of the crank is fixedly connected with the large gear, and the crank and the rack form an eccentric crank rocker mechanism; the adjusting device comprises a limiting sliding block and a fan-shaped roller; the vertical swing angle of the wing can be adjusted by changing the radius of the fan-shaped roller or the connecting position of the fan-shaped roller and the supporting plate. Through the structural design, the vertical swing angles of the wings of the ornithopter can be adjusted according to the use environment, so that larger flight lift force is obtained, and the flight efficiency is improved.

    本发明涉及一种翅翼挥拍角可调节的微型扑翼飞行器,属于微型仿生飞行器领域,包括机架部分、传动装置、扑动装置以及调节装置。机架部分包括机身、头部、尾翼和配重平衡块,头部、尾翼与机身固定连接;传动装置包括电机、减速齿轮组和传动齿轮,两个大齿轮相互啮合实现两侧翅翼同步对称运动;扑动装置包括曲柄、齿条、翅翼,曲柄一端与大齿轮固连,和齿条一起构成偏心曲柄摇杆机构;调节装置包括限位滑块、扇形滚轮;通过更改扇形滚轮的半径大小或者其与支撑板连接的位置,即可调节翅翼上下挥拍角度。通过本发明的结构设计,能够根据使用环境对扑翼飞行器翅翼上下挥拍角进行调节,从而获得更大的飞行升力,提高飞行效率。
