The invention discloses an ornithopter which comprises an ornithopter body, wings, a power source, a transmission mechanism and a driving mechanism. The wings comprise wing bodies and wing mounting seats which are symmetrically arranged about the center line of the aircraft body, the driving mechanism comprises a space crank-link mechanism and a plane crank-link mechanism, and the space crank-link mechanism comprises crank-link assemblies which are symmetrically arranged about the center line of the aircraft body; each crank connecting rod assembly comprises a crank, a connecting rod, a rocker and a machine body which are necessary for forming the four connecting rods, one end of the crank is connected with the transmission mechanism, the other end of the crank is connected with one end of the connecting rod, and the other end of the connecting rod is connected with the wings; the plane crank-link mechanism is responsible for the twisting action of the wings. According to the combined type driving mechanism, the number of power sources is reduced, the weight of the whole machine is lighter, meanwhile, the motion freedom degree of the wings is increased, the tracks of the tail ends of the wings are in a spatial 8 shape, birds can be better simulated to move, and the ornithopter integrally moves more stably.
本发明公开了一种扑翼飞行器,包括:机体、机翼、动力源、传动机构以及驱动机构;机翼包括以机体的中心线对称设置的机翼本体以及机翼安装座,驱动机构包括空间曲柄连杆机构和平面曲柄连杆机构,空间曲柄连杆机构包括以机体的中心线对称布置的曲柄连杆组件;每个曲柄连杆组件包含构成四连杆所必须的曲柄、连杆、摇杆以及机体四个组件,曲柄的一端与传动机构连接,曲柄的另一端与连杆的一端连接,连杆的另一端与机翼连接;平面曲柄连杆机构负责机翼的扭转动作。此组合式驱动机构减少了动力源数量,使整机重量更轻,同时增加了机翼的运动自由度,机翼末端轨迹呈空间“8”字形,能更好地仿生鸟类运动,整体上使扑翼飞行器运动更平稳。
