The invention discloses a rotor secondary unfolding mechanism and method of a coaxial dual-rotor unmanned aerial vehicle, an upper rotor primary unfolding mechanism and a lower rotor secondary unfolding mechanism are arranged on a phase arm of an unmanned aerial vehicle body, and the lower rotor secondary unfolding mechanism comprises a lower rotor, a secondary elastic mechanism and a condition limiting paddle clamp; a supporting main body of the secondary elastic mechanism is connected with a phase arm of the unmanned aerial vehicle body; the secondary elastic mechanism is rotationally connected with the condition limiting paddle clamp, and the condition limiting paddle clamp is fixedly connected with the lower rotor wing. According to the rotor wing secondary unfolding mechanism of the coaxial double-rotor-wing unmanned aerial vehicle and the method thereof, the size is small, the function is reliable, and the lower rotor wing of the unmanned aerial vehicle can be unfolded twice, so that the lower rotor wing is unfolded from a storage state to a working state; the unfolding mechanism efficiently avoids the risk of upper and lower rotor propeller beating after the unmanned aerial vehicle is launched from the launch canister.
本发明公开了一种共轴双旋翼无人机的旋翼二次展开机构及其方法,无人机机体的相位臂上设有上旋翼一次展开机构和下旋翼二次展开机构,下旋翼二次展开机构包括下旋翼、二次弹力机构和条件限位桨夹;二次弹力机构的支撑主体与无人机机体的相位臂连接;二次弹力机构与条件限位桨夹之间转动连接,条件限位桨夹与下旋翼之间固定连接。本发明提供的一种共轴双旋翼无人机的旋翼二次展开机构及其方法,体积小巧,功能可靠,能实现无人机的下旋翼分两次展开,使其从收纳状态展开到工作状态;该展开机构高效避免无人机从发射筒发射后上下旋翼打桨的风险。
