The invention belongs to the technical field of morphing aircrafts, and discloses a connecting rod type mechanism for wing tip turning of a morphing aircraft. Comprising a double-four-rod symmetrical movement mechanism, a driving rod and a driving unit of the driving rod, wherein the double-four-rod symmetrical movement mechanism consists of a vertical rod, an inclined long rod and an inclined short rod, and two sides of the vertical rod are connected with wing ribs. Two or more connecting rod mechanism modules can be connected in parallel, and single drive is achieved through one rigid rod. The driving element transmits force to the vertical rod on the right side through the driving rod to achieve mechanism turning, and the rotation center is located on the outer side of all the movable mechanisms, so that upper and lower skins of a turning section of the wing are both pulled in the turning process, the skin wrinkling or swelling phenomenon is avoided, and the phenomenon that wingtip deformation and pneumatic discontinuity are easily solved.
本发明属于变体飞行器技术领域,公开了一种用于变体飞行器的翼尖折转的连杆式机构。包括两侧与机翼翼肋相连的竖直杆、斜长杆、斜短杆构成的双四杆对称运动机构和驱动杆及其驱动单元。本发明可并联两个及两个以上的连杆机构模块并通过一个刚性杆实现单驱动。驱动原件通过驱动杆将力传给右侧竖直杆实现机构折转,回转中心在所有活动机构的外侧,可使机翼在折转过程中折转段上下蒙皮均受拉力,避免蒙皮起褶或鼓包现象的发生,有利于解决翼尖变形气动不连续的现象。
