The invention discloses an unmanned aerial vehicle with rotor wing protective covers as parachutes, and belongs to the technical field of unmanned aerial vehicle parachutes, the unmanned aerial vehicle comprises an unmanned aerial vehicle main body, a plurality of wing assemblies are uniformly distributed around the unmanned aerial vehicle main body, and separable rotor wing protective cover assemblies are annularly distributed on the outer sides of the wing assemblies; openings are formed in the rotor wing protective cover assemblies, the opening ends of any two adjacent rotor wing protective cover assemblies are hinged to each other, and the multiple rotor wing protective cover assemblies form a closed annular structure; a folding umbrella assembly is connected to the side, close to the unmanned aerial vehicle body, between the multiple rotor wing protective cover assemblies. According to the parachute, the multiple rotor wing protective cover assemblies which are annularly connected are adopted as the parachute edge structure of the parachute, and the bendable elastic belt body which is originally used as a fan blade protection structure can be bounced off, so that the bendable elastic belt body is freely opened and serves as the parachute edge structure of the parachute; therefore, the edge of the parachute structure can be expanded, and the possibility of automatic folding of the parachute is reduced.
本发明公开了一种将旋翼护罩作为降落伞的无人机,属于无人机降落伞技术领域,包括无人机主体,所述无人机主体四周均匀环绕分布有多个机翼组件,多个所述机翼组件外侧均环形分布有可分离的旋翼护罩组件,所述旋翼护罩组件均设置有开口,相邻的任意两个旋翼护罩组件的开口端均互相绞接,多个所述旋翼护罩组件形成闭合的环状结构;多个所述旋翼护罩组件之间靠近无人机主体的一侧连接有折叠伞组件。本发明中,采用了呈环形连接的多个旋翼护罩组件作为降落伞的伞边结构,可实现将原本作为扇叶保护结构的可折弯弹性带体弹开,使可折弯弹性带体自由张开并作为降落伞的伞边结构,以便于将降落伞结构边缘处撑开并减少降落伞自行合拢的可能性。
