The variable-length unmanned aerial vehicle wing comprises an inner wing, an outer wing, a pulley assembly, a power device and a force storage device, the inner wing and the outer wing are telescopically connected in a sleeved mode, the pulley assembly comprises a fixed pulley and a movable pulley which are connected with each other, and the output end of the fixed pulley is fixedly connected with the end of one side of the outer wing; one end of the movable pulley is connected with the power device through a steel wire, one end of the force storage device is fixedly connected to the end part of one side of the inner wing, and the other end of the force storage device is fixedly connected to the end part of one side of the outer wing, so that the force storage device is used for storing force when the inner wing and the outer wing contract and providing assistance when the inner wing and the outer wing extend. According to the structure, when the wings extend, through the combination of the fixed pulley and the movable pulley, the burden of the motor can be greatly saved, when the wings contract, the rebound assisting force of the force storage device is achieved, the output power of the power device can be greatly reduced, the durability of the power device is improved, and the device is simple in structure and small in installation difficulty.
本发明公开了一种可变长度无人机机翼,包括内翼、外翼、滑轮组件、动力装置和蓄力装置,所述内翼和外翼可伸缩式相互套接,所述滑轮组件包括相互连接的定滑轮和动滑轮,其中定滑轮的输出端与外翼一侧的端部固定连接,动滑轮的一端则通过钢丝与动力装置连接,所述蓄力装置的一端固定连接在内翼的一侧端部、另一端固定连接在外翼的一侧端部,以供内翼和外翼收缩时蓄力和伸长时提供助力,本发明通过解决了传统无人机机翼长度不可调节的问题,且此种结构,机翼伸长时,通过定滑轮和动滑轮的组合,可大大节省电机负担,而收缩时又有了蓄力装置的反弹的助力,可大大减轻动力装置的输出功率,增加动力装置耐用性,本发明结构简单,安装难度小。
