The invention discloses an unmanned aerial vehicle and an actuation mechanism of a folding airfoil of the unmanned aerial vehicle. The actuation mechanism comprises a driving shaft, a driven shaft, an arc-shaped sliding rail, a clamping ring and a check block. A first bevel gear is mounted on the driving shaft, and a second bevel gear and a deflector rod are mounted on the driven shaft; a separating opening is formed in the extending tail end of the arc-shaped sliding rail, and a clamping ring opening right opposite to the separating opening is formed in the clamping ring. When the arc-shaped sliding block slides to the unfolding position, the driven shaft just slides into the clamping ring from the opening of the clamping ring while the arc-shaped sliding block slides out of the opening and is separated from the opening; the driving shaft rotates in the storage direction to drive the shifting rod to extrude the check block, then the driven shaft is separated from the clamping ring, the arc-shaped sliding block enters the arc-shaped sliding rail, and the driving shaft continues to rotate to drive the arc-shaped sliding block to slide to the storage position along the arc-shaped sliding rail. The folding and unfolding of the folding airfoils and the control of the flight angle can be simultaneously realized by only one set of the actuation mechanism, and the problem that the size, weight and complexity of the unmanned aerial vehicle are increased due to the actuation mechanism is avoided.

    本发明公开了一种无人机及其折叠翼面的作动机构,包括主动轴、从动轴、圆弧形滑轨、卡环和挡块;主动轴上安装有第一锥齿轮,从动轴上安装有第二锥齿轮和拨杆;圆弧形滑轨的延伸末端形成有脱离开口,卡环上形成有正对脱离开口布置的卡环开口;当圆弧形滑块滑动至展开位时,圆弧形滑块滑出脱离开口的同时从动轴刚好自卡环开口滑入卡环内;主动轴向收纳方向转动能够带动拨杆挤压挡块,继而从动轴脱离卡环,圆弧形滑块进入圆弧形滑轨,主动轴继续转动能够带动圆弧形滑块沿圆弧形滑轨滑动至收纳位。仅需一套作动机构能够同时实现折叠翼面的收展和飞行角度控制,避免了因作动机构导致无人机尺寸、重量及复杂度均会变大的问题。
