A multi-rotor unmanned aerial vehicle comprises a frame (10), rotors (20) and an elastic member (30). The rotor wing (20) comprises a motor (21), a propeller (22) and a fixing piece (23), the motor (21) is installed on the rack (10), the fixing piece (23) is fixed to the motor (21) and rotates along with a rotor of the motor (21), the propeller (22) is installed on the motor (21) through the fixing piece (23), and the motor (21) drives the propeller (22) to rotate. The elastic piece (30) is in mechanical coupling connection with a propeller seat (221) of the propeller (22) and is used for providing elastic force to the propeller seat (221) of the propeller (22); a propeller seat (221) of the propeller (22) is provided with a through hole (223) and a clamping groove (224), the fixing piece (23) can penetrate through the through hole (223) and rotate by a preset angle relative to the propeller seat (221) of the propeller (22) to be clamped with the clamping groove (224), and the propeller (22) keeps the clamping groove (224) and the fixing piece (23) in a clamped state under the elastic force action of the elastic piece (30), so that the motor (21) drives the propeller (22) to rotate through clamping and fixing of the fixing piece (23) and the clamping groove (224).
一种多旋翼无人飞行器,包括机架(10)、旋翼(20)、弹性件(30)。旋翼(20)包括电机(21)、螺旋桨(22)以及固定件(23),电机(21)安装在机架(10)上,固定件(23)固定在电机(21)上,并且随电机(21)的转子一起转动,螺旋桨(22)通过固定件(23)安装在电机(21)上,电机(21)带动螺旋桨(22)旋转。弹性件(30)与螺旋桨(22)的桨座(221)机械耦合连接,用于提供一弹力给螺旋桨(22)的桨座(221);螺旋桨(22)的桨座(221)设有通孔(223)及卡槽(224),固定件(23)能够从通孔(223)穿过,并相对于螺旋桨(22)的桨座(221)旋转预设角度后与卡槽(224)相卡合,并且螺旋桨(22)在弹性件(30)的弹力作用下保持卡槽(224)与固定件(23)处于卡合状态,使电机(21)通过固定件(23)与卡槽(224)卡合固定带动螺旋桨(22)旋转。
