请参阅图4至图7，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。例如，多个第一支杆11与多个第二支杆12交叉呈整体大致为方形的网格状。第一支杆11的数量可以与第二支杆12的数量相等，以形成均匀的网格。当保护罩10处于展开状态时，第一方向与第二方向不同。在图4至图7的例子中，第一方向和第二方向分别为方形网格的两个相邻边的延伸方向。第一方向与第二方向交叉呈钝角。在其他例子中，第一方向与第二方向也可以相互垂直。请参阅图2，在某些实施方式中，当保护罩10处于展开状态时，第一方向可以与无人机100的第一机臂41的延伸方向大致平行，第二方向可以与无人机100的第二机臂42的延伸方向大致平行，第一机臂41与第二机臂42分别位于无人机100的机身30的相对两侧。
请参阅图7和图8，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。可选地，当保护罩10处于折叠状态时，第一方向与第二方向可以是相同的。
请参阅图4和图5，阻挡件13的数量为多个，例如两个、三个、四个、六个等。多个阻挡件13设置在第一支杆11及第二支杆12的端部，也即，每个第一支杆11及每个第二支杆12的端部均设有阻挡件13，或者部分第一支杆11及部分第二支杆12的端部设有阻挡件13。例如，一部分阻挡件13设置在第一支杆11的端部，另一部分阻挡件13设置在第二支杆12的端部。阻挡件13的长度方向(或延伸方向)可以同时与第一方向及第二方向垂直。多个第一支杆11、多个第二支杆12、及多个阻挡件13形成用于收容螺旋桨50的收容空间17。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。请结合图1和图2，以无人机100是四旋翼无人机为例，无人机100包括四个螺旋桨50，每个螺旋桨50旋转形成一个圆形的桨盘51，因此共形成四个桨盘51，多个阻挡件13至少部分遮挡每个桨盘51的外周缘511，以在桨盘51的周向上保护螺旋桨50。需要指出的是，桨盘51为示意性画出的虚拟结构，并不实际存在。
