The invention discloses a wing folding mechanism for a small unmanned aerial vehicle and relates to the field of small unmanned aerial vehicles. The problems that an existing folding wing mechanism cannot push a wing to rotate by 90 degrees, a steering engine needs to continuously output power at the folding position and the unfolding position to achieve the self-locking function, a large amount of energy is wasted, and the service life of the steering engine is shortened are solved. When the steering engine rotates anticlockwise, the sliding block moves leftwards along the wave-shaped sliding way, so that the rotating wing connecting piece is driven to rotate anticlockwise; when the sliding block slides across the inflection point of the wave-shaped slide way, the angle of the connecting line of the sliding block and the axis of the rotating shaft cannot be continuously changed, the rotating wing connecting piece stops rotating, and the wing reaches the folding position. However, under the continuous pushing of the steering engine, the sliding block can continuously slide to the end point of the upper left portion of the wave-shaped sliding way along the sliding way, so that the sliding block is clamped by the wave-shaped sliding way, and then self-locking of the mechanism is achieved. The invention is suitable for the field of small unmanned aerial vehicles.

    一种用于小型无人机的机翼折叠机构,涉及小型无人机领域。为解决现有的折叠机翼机构无法推动机翼实现90°转动,并且在折叠位置和展开位置时需要舵机持续的输出功率,才能实现自锁的功能,从而导致大量能源的浪费,并且导致舵机使用寿命缩短的问题。当舵机逆时针转动时,滑块会沿波浪形滑道向左运动,从而带动转动机翼连接件逆时针转动;当滑块滑过波浪形滑道的拐点时,滑块和转轴轴心连线的角度不会继续改变,转动机翼连接件停止转动,机翼到达折叠位置。但在舵机的持续推动下,滑块会沿滑道继续滑动至波浪形滑道的左上方端点,从而滑块将被波浪形滑道卡住,进而实现机构自锁。本发明适用于小型无人机领域。
