A paddle, a propeller, a power assembly and a multi-rotor unmanned aerial vehicle, where the paddle (10) comprises a main body portion (11) and an edge portion (12), the edge portion (12) is arranged around the main body portion (11), at least part of the edge portion (12) comprises a soft layer (121) away from the main body portion (11) and a middle layer (122) close to the main body portion (11), the soft layer (121) is connected to the main body portion (11) through the middle layer (122), and the soft layer (121) is connected to the main body portion (11) through the middle layer (122). And the cross section of the middle layer (122) along the width direction of the paddle or the cross section along the length direction of the paddle comprises a structure formed by stacking a soft part (1221) and a hard part (1222). According to the paddle, the soft layer is arranged on at least part of the edge part, so that when the paddle hits a human body, the soft layer can play a buffering role, and the harm to the human body is effectively reduced.
一种桨叶、螺旋桨、动力组件及多旋翼无人机,其中,桨叶(10)包括主体部(11)和边缘部(12),边缘部(12)围绕主体部(11)周围设置,至少部分边缘部(12)包括远离主体部(11)的软质层(121)和靠近主体部(11)的中间层(122),软质层(121)通过中间层(122)与主体部(11)连接,其中,中间层(122)沿桨叶宽度方向的截面或者沿桨叶长度方向的截面包括软质件(1221)和硬质件(1222)层叠设置的结构。上述桨叶通过在至少部分的边缘部设置软质层,当桨叶打到人体时,软质层可以形成缓冲作用,有效地降低对人体的伤害。
