The invention discloses a foldable rotor unmanned aerial vehicle which comprises an unmanned aerial vehicle body, a plurality of rotor arms are hinged to the lower end face of the unmanned aerial vehicle body, and the rotor arms can synchronously swing up and down along the unmanned aerial vehicle body so as to be switched back and forth between a first pose and a second pose. The unmanned aerial vehicle is characterized by further comprising an unfolding mechanism connected with the unmanned aerial vehicle body and each rotorcraft arm, and the unfolding mechanisms can keep the rotorcraft arms in the first posture and drive the rotorcraft arms to swing to the second posture under the action of external force. An umbrella-shaped structure is formed among the unfolding mechanism, the unmanned aerial vehicle body and the rotorcraft arms, the center module slides along the fixing rod by compressing or releasing the spring, the push rod supporting frame hinged to the center module is driven to ascend and descend synchronously, the push rod supporting frame is connected with the rotorcraft arms and drives the rotorcraft arms to swing at the same time, and posture switching of the rotorcraft arms is achieved. And moreover, the folding chair can be automatically unfolded and is convenient to use, and the human efficiency is improved.

    本发明公开了一种可折叠旋翼无人机,包括无人机主体,无人机主体的下端面上铰接有多个旋翼机臂,多个旋翼机臂能同步沿着无人机主体上下摆动以在第一位姿和第二位姿之间来回切换,其特征在于:还包括连接无人机主体和每个旋翼机臂的展开机构,展开机构能将旋翼机臂保持在第一位姿,并在外力作用下带动旋翼机臂摆动到第二位姿。展开机构、无人机主体和旋翼机臂之间形成伞装结构,通过通过压缩或释放弹簧使中心模块沿固定杆滑动,带动与中心模块铰接的推杆支撑架同步升降,推杆支撑架同时连接旋翼机臂,带动旋翼机臂摆动,实现其位姿的切换。便于折叠存放,且可自动展开,便于上手,提高人效。
