The ornithopter comprises a flight mechanism, a rack and a turnover mechanism, the flight mechanism and the turnover mechanism are connected with the two ends of the rack correspondingly, the flight mechanism comprises two driving wheels and wings which are symmetrically arranged, one side of each driving wheel is rotationally connected with a first connecting rod, and the other side of each driving wheel is rotationally connected with a second connecting rod; the ends, away from the driving wheel, of the two first connecting rods are rotationally connected through a sliding rod, and the sliding rod is slidably connected with the rack. On the basis of improving the mechanism configuration and optimizing the rod length, the eccentric crank sliding block mechanism is provided by analyzing the basis of a two-dimensional crank rocker mechanism, and the problem of low efficiency caused by no difference of the upper flapping speed and the lower flapping speed of a flapping wing is solved under the condition of not increasing the energy dissipation of each component and the load of a flapping wing mechanism; therefore, the overall pneumatic performance and stability of the ornithopter are improved, and the requirements of small and medium-sized ornithopters are further met.
本发明中公开了一种基于偏心曲柄滑块机构的扑翼机,包括飞行机构、机架和翻转机构,所述飞行机构和翻转机构分别与机架的两端连接,所述飞行机构包括对称设置的两个主动轮和机翼,所述主动轮的一侧转动连接有第一连杆,两个所述第一连杆远离主动轮的一端通过滑杆转动连接,所述滑杆与机架滑动连接。本发明在改进机构构型、优化杆长的基础上,通过对二维曲柄摇杆机构基础进行分析,提出了一种偏心曲柄滑块机构,在不增加各部件的能量耗散、扑翼机构负载条件下,同时解决了扑翼上下扑动速度无差异带来的效率低的问题,从而提高扑翼机整体的气动性与稳定性,从而进一步满足中小型扑翼机的需要。
