The invention relates to a bird-imitating flapping-wing aircraft with two-degree-of-freedom foldable wings. The bird-imitating flapping-wing aircraft comprises an aircraft body, wing bone unfolding mechanisms, universal joint rotating mechanisms, plume rotating mechanisms and flapping-wing mechanisms, the wing bone unfolding mechanism comprises a driving assembly and a lead screw transmission assembly; the driving assembly is arranged in the middle of the upper surface of the body; the lead screw transmission assemblies are arranged on the two sides of the driving assembly correspondingly. The flapping wing mechanisms are arranged on two sides of the front end of the driving assembly; the plume rotating mechanisms are symmetrically arranged on the two sides of the fuselage, and the inner ends of the plume rotating mechanisms are connected with the driving assembly through the flapping wing mechanisms. The universal joint rotating mechanisms are correspondingly connected between the middles of the plume rotating mechanisms on the two sides and the lead screw transmission assembly. According to the bionic bird wing folding and unfolding device, bionic wing folding and unfolding actions of birds can be achieved, and wings have two degrees of freedom and are more flexible; in the folding and unfolding process of the wings, the wings can be parallel to the fuselage all the time, and the bionic effect is good. The folding and unfolding of the wings do not influence the swinging, so that the light weight is ensured, and the posture of a flying bird is simulated more truly.
本发明涉及一种拥有两自由度可折叠机翼的仿鸟扑翼飞行器,包括机身、翼骨展开机构、万向节转动机构、羽管转动机构和扑翼机构;翼骨展开机构包括驱动组件和丝杠传动组件;驱动组件设置在机身上表面中部;丝杠传动组件分别设置在驱动组件的两侧;扑翼机构设置在驱动组件前端的两侧;羽管转动机构对称设置在机身两侧,且其内端分别通过扑翼机构与驱动组件连接;万向节转动机构分别对应连接在两侧羽管转动机构的中部与丝杠传动组件之间。本发明能够实现对鸟类收放翅膀动作的仿生,且羽翼拥有两个自由度,更加灵活;翅膀在收放过程中,羽翼能始终平行于机身,仿生效果好。翅膀的收放不影响摆动,在保证轻量化的同时更真实的模仿飞鸟的姿态。
