The invention discloses a single-degree-of-freedom multi-configuration variant mechanism and a variant wing. Wherein the single-degree-of-freedom multi-configuration variant mechanism is formed by four closed-loop rod group units through two times of approximate symmetric networking; the closed-loop rod group unit is a 6R mechanism capable of being switched between a planar motion configuration and a Bennett motion configuration, and comprises a first rod piece, a second rod piece, a third rod piece, a fourth rod piece, a fifth rod piece and a sixth rod piece which are sequentially connected end to end, and the first rod piece, the second rod piece, the third rod piece, the fourth rod piece, the fifth rod piece and the sixth rod piece are sequentially and rotatably connected through a rotating pair R1, a rotating pair R2, a rotating pair R3, a rotating pair R4, a rotating pair R5 and a rotating pair R6; when the closed-loop rod group unit is located at the singular position where the planar motion configuration and the Bennett motion configuration are switched, the rotation axes of the rotation pairs R1, R2, R4 and R5 are parallel to one another, the rotation pairs R2, R3, R4 and R5 are located in the same plane, and the rotation axes of the rotation pairs R3 and R6 constantly intersect at one point. The invention has the advantages of good stability and high reliability.
本发明公开了一种单自由度多构态变体机构以及变体机翼。其中,单自由度多构态变体机构通过四个闭环杆组单元经两次近似对称组网形成;闭环杆组单元为可在平面运动构态与Bennett运动构态之间切换的6R机构,包括依次首尾相连的第一杆件、第二杆件、第三杆件、第四杆件、第五杆件和第六杆件,第一杆件、第二杆件、第三杆件、第四杆件、第五杆件和第六杆件依次通过转动副R1、R2、R3、R4、R5、R6可转动地连接;闭环杆组单元处于平面运动构态与Bennett运动构态相切换的奇异位置下,转动副R1、R2、R4、R5的回转轴线互相平行,转动副R2、R3、R4、R5处于同一平面内,转动副R3、R6的回转轴线恒交汇于一点。本发明具有稳定性好及可靠性高的优点。
