A multi-rotor unmanned aerial vehicle comprises a fuselage and at least three rotor mechanisms, each rotor mechanism comprises a rotor, a protective cover arranged outside the rotor and a connecting mechanism, the protective cover is arranged outside the rotor, each rotor mechanism is movably connected to the fuselage through the corresponding connecting mechanism, and the rotor mechanisms are movably connected to the fuselage through the connecting mechanisms. The at least three rotor mechanisms rotate relative to the corresponding connecting mechanisms and can be mutually overlapped to form a coaxial rotor mechanism assembly, and the protective covers of the at least three rotor mechanisms are mutually overlapped to form a cylinder structure. According to the multi-rotor unmanned aerial vehicle, the rotor mechanisms are movably connected to the vehicle body through the connecting mechanisms, so that the rotor mechanisms can be mutually overlapped to form the rotor mechanism combination body after rotating relative to the corresponding connecting mechanisms, and the formed rotor mechanism combination body greatly reduces the size of the folded multi-rotor unmanned aerial vehicle.

    一种多旋翼无人机,包括机身以及至少三个旋翼机构,每个所述旋翼机构包括旋翼、设置于所述旋翼外部的保护罩以及连接机构,所述保护罩设置于所述旋翼外部,每个所述旋翼机构通过对应的所述连接机构活动连接于所述机身,其中,至少三个所述旋翼机构相对各自对应的所述连接机构进行转动,能够相互重叠形成同轴心的旋翼机构组合体,并且至少三个所述旋翼机构的保护罩相互重叠形成柱体结构。通过连接机构将旋翼机构活动连接于机身上,以使得多个旋翼机构相对各自对应的连接机构进行转动后,能够相互重叠形成旋翼机构组合体,形成的旋翼机构组合体极大的缩小了多旋翼无人机折叠后的体积。
