A protective cover (10) of a propeller (50) comprises a plurality of first supporting rods (11), a plurality of second supporting rods (12) and a plurality of stoppers (13). The first supporting rods (11) and the second supporting rods (12) can rotate relatively, so that the protective cover (10) can be switched between an unfolded state and a folded state. When the protective cover (10) is in the unfolded state, the plurality of first supporting rods (11) and the plurality of second supporting rods (12) are crossed to form a grid shape; when the protective cover (10) is in the folded state, the first supporting rods (11) are sequentially attached to one another, and the second supporting rods (12) are sequentially attached to one another. The multiple stoppers (13) are used for at least partially blocking the outer periphery (511) of a propeller disc (51) formed by rotation of each propeller (50). The invention further provides an unmanned aerial vehicle (100) which comprises the protective cover (10).
一种螺旋桨(50)的保护罩(10),包括多个第一支杆(11)、多个第二支杆(12)和多个阻挡件(13)。第一支杆(11)与第二支杆(12)能够相对转动,以使得保护罩(10)能在展开状态与折叠状态之间切换。当保护罩(10)处于展开状态时,多个第一支杆(11)与多个第二支杆(12)交叉呈网格状;当保护罩(10)处于折叠状态时,多个第一支杆(11)依次贴紧,多个第二支杆(12)依次贴紧。多个阻挡件(13)用于至少部分遮挡每个螺旋桨(50)旋转形成的桨盘(51)的外周缘(511)。以及一种无人机(100),包括所述保护罩(10)。
