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 an X-shaped lifting component, a cylindrical key, a connecting rod, a screw rod, a rotary driving motor, a base connecting component and a bent connecting rod, the X-shaped lifting component is spirally matched with the screw rod, and the rotation of the screw rod can drive the X-shaped lifting component to translate; four grooves are symmetrically formed in the X-shaped lifting component, are coaxially matched with the four bent connecting rods through cylindrical keys, and can rotate relatively; a through hole is formed in the bent connecting rod, and the bent connecting rod and the connecting rod are coaxially matched through a cylindrical key and can rotate relatively; same holes are formed in the two ends of the connecting rod, and the connecting rod is coaxially matched with the bent connecting rod and the base connecting piece through cylindrical keys and rotates relatively; the base connecting piece is fixedly connected to the machine body; the unmanned aerial vehicle has the advantages that the wings can be self-locked after being unfolded, the overall structure is simple, the size is small, and the bearable load is large.

    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,该折展机构包括X形升降构件、圆柱键、连杆、螺杆、旋转驱动电机、底座连接构件和弯曲连杆;X形升降构件与螺杆构成螺旋配合,螺杆的转动可以带动X形升降构件平动;X形升降构件上对称地设有4个凹槽,通过圆柱键与4个弯曲连杆构成同轴配合,可相对转动;弯曲连杆上设有通孔,通过圆柱键与连杆构成同轴配合,可相对转动;连杆两端设有同孔,通过圆柱键分别与弯曲连杆和底座连接件构成同轴配合,相对转动;底座连接件固连在机身上;本申请具有机翼展开后可自锁,整体结构简单,体积小,可承受载荷大等优点。
