The invention discloses a deformable wing mechanism, and relates to the technical field of wings. The mechanism is formed by coupling a plurality of space 6R mechanisms and connecting mechanisms, forms a double-layer folding and unfolding structure, and has a single degree of freedom. By networking a plurality of space 6R mechanisms, adjustability of three modes of sweepback, elongation and wing bending of the wing can be realized, and the elongation and the wing bending can be synchronously adjusted. The aerodynamic layout and characteristics of the aircraft are optimized by adjusting the sweepback angles of the wings, and the performance requirement of the wide speed range is met. Meanwhile, the area and the aspect ratio of the wings are adjusted by changing the extension length and the wing bending of the wings, so that the aerodynamic performance is optimized according to different flight environments and tasks. The design can effectively improve the lift-drag ratio of the aircraft, shorten the take-off and landing distance, prolong the endurance time and improve the flight speed, and has the advantages of reducing the total weight of the aircraft and increasing the voyage.

    本发明公开了一种可变形翼机构,涉及机翼技术领域。该机构由多个空间6R机构和连接机构耦合组成,形成双层折展结构,具备单一自由度。通过组网多个空间6R机构,可实现机翼后掠角、展长和翼弯三种模式的可调节,其中展长和翼弯可同步调整。本发明通过调整机翼后掠角来优化飞行器的气动布局与特性,满足宽速域的性能需求。同时,通过改变机翼的展长和翼弯,调整机翼面积和展弦比,从而根据不同飞行环境和任务,优化气动性能。该设计可有效提高飞行器的升阻比,缩短起降距离,延长续航时间,提升飞行速度,并具备减轻飞机总重和增加航程的优势。
