The ornithopter comprises a main beam, folding and unfolding steering engines are symmetrically installed on the two sides of the main beam, and humerus assemblies and second connecting rods located below the humerus assemblies are arranged on the two sides of the main beam; a radius component is movably connected to one end, far away from the main beam, of the humerus component; one end of the second connecting rod away from the girder is movably connected with a first connecting rod; the radius assembly is movably connected with the first connecting rod through the wing rib assembly, a parallelogram-shaped folding and unfolding structure is formed, the folding and unfolding steering engine is connected to the second connecting rod through the driving assembly, and the folding and unfolding steering engine can drive the folding and unfolding structure to fold and unfold. The wing ribs and the radius form a parallelogram folding and unfolding structure, the strength of the radius is enhanced, the whole folding and unfolding structure is movably connected, the folding and unfolding structure is driven to move smoothly and is not prone to being blocked, the driving stroke of the steering engines is short, folding and unfolding response is fast, the wings on the two sides are independently controlled by the steering engines to be folded and unfolded, and rapid steering of the ornithopter can be achieved. And the flying capability of the folding and unfolding wings is improved.
本发明公开了一种具有可折展翅膀的扑翼飞行器,包括主梁,主梁的两侧对称式安装有折展舵机,在主梁的两侧均设有肱骨组件以及位于肱骨组件下方的连杆二;肱骨组件远离主梁的一端活动连接有桡骨组件;连杆二远离主梁的一端活动连接有连杆一;桡骨组件与连杆一之间通过翼肋组件活动连接,并形成平行四边形状的折展结构,其中折展舵机通过驱动组件连接到连杆二,折展舵机能够驱动折展结构折展。其中翼肋与桡骨组成平行四边形结构的折展结构,增强桡骨强度,整体活动连接,驱动折展结构运动顺滑,不易卡顿,舵机驱动行程短,折展响应快,并且两侧翅膀分别采用舵机进行单独控制折展,可以实现扑翼飞行器快速转向,提升了折展翅膀的飞行能力。
