The invention discloses an unmanned aerial vehicle capable of replacing rotor wings. The unmanned aerial vehicle comprises a vehicle body, vehicle arms, a rotor wing combination, a replaceable rotor wing combination, a limiting locking mechanism, an ejection replacing mechanism and a storage bin. The storage bin is arranged on the inner side of each machine arm; and the alternative rotor combination, the limiting and locking mechanism and the ejection mechanism are all arranged in the storage bin. When the unmanned aerial vehicle flies normally, the alternative rotor wing combination is arranged in the storage bin. And when the rotors are damaged or the motor breaks down in the flight process of the unmanned aerial vehicle, the ejection mechanism rapidly unbuckles to eject the faulted rotor combination and replace the faulted rotor combination with the alternative rotor combination. Meanwhile, the alternative rotor combination is limited and locked by the limiting and locking mechanism, and the motor is connected to a power supply, so that the rotor rotates to recover the lift force. According to the invention, the unmanned aerial vehicle is prevented from being correspondingly damaged due to the rotor wing fault to stop the flight task to a certain extent, and the error-tolerant rate of the unmanned aerial vehicle in the flight process and the success rate of the flight task are improved.

    本发明专利公开了一种可顶替旋翼的无人机,包括机体,机臂,旋翼组合,替用旋翼组合,限位锁紧机构,弹射顶替机构以及收纳仓;收纳仓设置于每个机臂的内侧;替用旋翼组合,限位锁紧机构以及弹射机构均置于收纳仓内。当无人机正常飞行时,替用旋翼组合置于收纳仓内。当无人机飞行过程中出现旋翼损坏或电机故障时,弹射机构快速进行解扣将故障的旋翼组合弹出并替换为替用旋翼组合。同时限位锁紧机构将替用旋翼组合限位锁紧并使电机接入电源,使旋翼旋转恢复升力。本发明专利在一定程度上避免了无人机因旋翼故障受到相应的损伤而中止飞行任务,提升了无人机在飞行过程中的容错率与飞行任务的成功率。
