The invention discloses a telescopic wing mechanism suitable for a small unmanned aerial vehicle. The telescopic wing mechanism is formed by nesting an inner wing and an outer wing, and the length of the wings is adjusted in a manner that the inner wing is fixed relative to the fuselage of the unmanned aerial vehicle and the outer wing slides relative to the inner wing. When the telescopic wing works, the steering engine of the inner side wing drives the ball screw to move, so that the screw nut moves along the preset guide rail, the moving process of the outer side wing relative to the inner side wing is completed, and the length of the wing is adjusted. A ball screw transmission mode is adopted, and the problem that the wing length of the unmanned aerial vehicle cannot be adjusted according to flight requirements when the unmanned aerial vehicle flies is solved.
本发明公开了一种适用于小型无人机的可伸缩机翼机构,采用内、外侧机翼相嵌套的方式构成可伸缩的机翼机构,以内侧机翼相对无人机机身固定,外侧机翼相对内侧机翼滑动的方式调节机翼翼长。该可伸缩机翼工作时,内侧机翼的舵机带动滚珠丝杠运动,使丝杠螺母沿预设导轨移动,完成外侧机翼相对内侧机翼的移动过程,实现对机翼翼长的调节。本专利采用滚珠丝杠传动方式,解决了无人机在飞行时机翼翼长无法根据飞行需要进行调节的问题。
