The invention discloses a wing folding and unfolding mechanism suitable for a vertical take-off and landing aircraft. The wing folding and unfolding mechanism comprises a base structure; a folding and unfolding execution mechanism; the folding and unfolding executing mechanism comprises a first revolute pair, a second revolute pair and a driving rod piece, the wing is divided into a spar part and a blade part, the inner side of the spar part is arranged on the base structure through the first revolute pair and can horizontally rotate on the base structure in the x-y axis, and the outer side of the spar part is connected with the driving rod piece through the second revolute pair; the second revolute pair is provided with a through hole in the x-axis direction, the driving rod piece penetrates through the through hole to form clearance fit, and the first revolute pair serves as a fixed fulcrum, and folding and unfolding movement of the wing in the x-y axis is achieved through movement of the driving rod piece in the y-axis direction; a servo transmission mechanism; the servo transmission mechanism is arranged on the base structure and drives the driving rod piece to move on the y axis. By adopting the structure, the wings of the unmanned aerial vehicle can be stably and quickly folded and unfolded.
本发明公开了一种适用于垂直起降飞行器的机翼折展机构,包括:底座结构;折展执行机构;所述折展执行机构包括第一转动副、第二转动副及主动杆件,机翼分为翼梁部和叶片部,其翼梁部的内侧通过第一转动副设于底座结构上,可在底座结构上x‑y轴内水平转动,其翼梁部的外侧通过第二转动副连接主动杆件,所述第二转动副开设x轴方向的通孔,主动杆件穿过该通孔内形成间隙配合,以第一转动副为固定支点,通过主动杆件在y轴方向上的运动实现机翼在x‑y轴的折展运动;伺服传动机构;所述伺服传动机构置于底座结构上,驱动主动杆件在y轴上运动。采用以上结构可实现无人机机翼稳定快速的折展。
