The invention discloses a bird-like folding wing mechanism which comprises a base and a sliding block, the sliding block is hinged to one end of a short connecting rod A through a hinge A, the other end of the short connecting rod A is hinged to the end of a short connecting rod B through a hinge C, and the middle and the end of the short connecting rod B are hinged to the middle of a short connecting rod D and the middle of a short connecting rod C through a hinge D and a hinge I respectively; one end of the short connecting rod D and one end of the short connecting rod C are hinged to the long connecting rod B through a hinge E and a hinge, an end hinge is arranged at the end of the long connecting rod B, and the other end of the short connecting rod D and the other end of the short connecting rod C are hinged to the long connecting rod A through a hinge G and a hinge H. The long connecting rod A is hinged to the end of the base through a hinge J. The middle of the long connecting rod A and the middle of the short connecting rod A are hinged together through a hinge B. The mechanism is simple in structure, high in precision and capable of meeting the high lift force requirement for takeoff, the high lift and resistance requirements for landing and the high lift-drag ratio requirement for level flight, and the small aspect ratio can meet the high-speed flight requirement.
本发明公开了一种仿鸟的折叠机翼机构,它包括:底座和滑块,所述的滑块与短连杆A的一端通过铰链A铰接,短连杆A的另一端通过铰链C与短连杆B的端部铰接,短连杆B的中间处和端部分别与短连杆D和短连杆C的中间处通过铰链D和铰链I铰接,所述的短连杆D和短连杆C的一端与长连杆B通过铰链E和铰链铰接,长连杆B的端部设有端部铰链,短连杆D和短连杆C的另一端与长连杆A通过铰链G和铰链H铰接,所述的长连杆A通过铰链J铰接在底座的端部,长连杆A和短连杆A的中间处通过铰链B铰接在一起,该机构结构简单,精度高,能够满足起飞的高升力要求,降落的高升以及阻力要求,同时也能满足平飞时的高升阻比要求,小展弦比能满足高速飞行。
