A multi-rotor unmanned aerial vehicle comprises a frame (10), a forward rotor (20) and a reverse rotor (30). The forward rotor (20) comprises a first motor (21), a first propeller (22) and a first elastic piece (23). The reversal rotor (30) includes a second motor (31), a second propeller (32), and a second elastic member (33). A propeller seat (221) of the first propeller (22) is provided with a first clamping part (224), and the first propeller (22) can slide in the axial direction of a rotating shaft of the first motor (21) until the first elastic piece (23) is clamped with the first clamping part (224), so that the first propeller (22) is limited in the axial direction of the rotating shaft of the first motor (21). A propeller seat (321) of the second propeller (32) is provided with a second clamping part, the second propeller (32) can slide in the axial direction of a rotating shaft of the second motor (31) until the second elastic piece (33) is clamped with the second clamping part, so that the second propeller (32) is limited in the axial direction of the rotating shaft of the second motor (31), and the second motor (31) drives the second propeller (32) to rotate through the second clamping part. According to the multi-rotor unmanned aerial vehicle, the propellers can be stably connected.
一种多旋翼无人飞行器包括机架(10)、正转旋翼(20)、反转旋翼(30)。正转旋翼(20)包括第一电机(21)、第一螺旋桨(22)以及第一弹性件(23)。反转旋翼(30)包括第二电机(31)、第二螺旋桨(32)以及第二弹性件(33)。第一螺旋桨(22)的桨座(221)设有第一卡合部(224),第一螺旋桨(22)能够沿第一电机(21)的旋转轴的轴向滑动,直至第一弹性件(23)与第一卡合部(224)相卡合,使第一螺旋桨(22)在第一电机(21)的旋转轴的轴向上被限位。第二螺旋桨(32)的桨座(321)设有第二卡合部,第二螺旋桨(32)能够沿第二电机(31)的旋轴的轴向滑动,直至第二弹性件(33)与第二卡合部相卡合,使第二螺旋桨(32)在第二电机(31)的旋转轴的轴向上被限位,第二电机(31)通过第二卡合部带动第二螺旋桨(32)旋转。上述多旋翼无人飞行器能够使螺旋桨保持稳定连接。
