The invention provides a rotor unmanned aerial vehicle. The unmanned aerial vehicle comprises a rack, a battery and a control module, wherein the rack is provided with at least four paddle arms, the rotor unmanned aerial vehicle further comprises at least four paddle assemblies, and each paddle assembly comprises a charging and discharging motor, a rotating shell arranged on an output shaft of the charging and discharging motor in a sleeving mode and paddles; the paddle assembly further comprises a paddle changing assembly which is arranged in the rotating shell and drives the paddle to rotate around the center shaft. According to the rotor unmanned aerial vehicle provided by the invention, the pitch angles of the blades can be changed by the variable pitch assemblies, and in the descending process of the unmanned aerial vehicle, the blades can be always kept in a rotating state in the descending process by adjusting the pitch angles of the blades; and meanwhile, a working mode of the charging and discharging motor is switched along with the change of the pitch angle of the blades, and the discharging mode of the charging and discharging motor is switched into the charging mode through the control module, so the battery is reversely charged by utilizing the autonomous rotation of the blades in the descending process. The invention further provides a method for prolonging the endurance of the rotor unmanned aerial vehicle.
本发明提供了一种旋翼无人机,包括机架、电池和控制模组,机架设置有至少四个桨臂,还包括至少四个桨叶组件,桨叶组件包括充放电电机、套设于充放电电机的输出轴上的旋转壳以及桨叶;桨叶组件还包括设置于旋转壳内驱动桨叶围绕中心轴自转的变桨组件。本发明所提供的本发明所提供的一种旋翼无人机具有变桨组件可以改变桨叶的节距角,在无人机下降的过程中,通过调节桨叶的节距角让桨叶可以在下降的过程中始终维持旋转状态;同时伴随着桨叶节距角的变化切换充放电电机的工作模式,通过控制模组将充放电电机的放电模式切换为充电模式,实现在下降过程中利用桨叶的自主旋转为电池反向充电。本发明还提供了一种旋翼无人机的续航延长方法。
