The invention discloses a rotor blade and an unmanned aerial vehicle driving device using the rotor blade, the rotor blade comprises two blade root parts and two blade tip parts, a plurality of middle parts are sequentially connected between each group of blade root parts and blade tip parts end to end, one end of each blade root part is provided with an annular part connected with an output shaft in a sleeved mode, and the other end of each blade root part is provided with an annular part connected with the output shaft in a sleeved mode. A limiting part is arranged on one side of the annular part, a first protruding part is arranged at the other end of the blade root part, and a first rigid reinforcing piece is movably arranged in the blade root part. The unmanned aerial vehicle driving device comprises a rack, a mounting groove used for mounting a driving motor is formed in the rack, two mounting holes are formed in the side wall of the mounting groove, push rods are movably inserted into the mounting holes, a limiting block is arranged on an output shaft of the driving motor, and rotor blades are connected to the limiting block in a pressed mode after being inserted into the output shaft. And the upper part of the rotor blade is fixed and limited through a nut. The large-size blade rotorcraft can be normally used in a strong wind environment.

    本发明公开了一种旋翼桨叶及使用旋翼桨叶的无人机驱动装置,旋翼桨叶包括两个叶根部和两个叶尖部,每一组叶根部和叶尖部之间收尾依次连接有若干个中间部,叶根部的一端设置有与输出轴套接的环形部,环形部的一侧设置有限位部,叶根部的另一端设置有第一凸起部,叶根部内活动设置有第一刚性加强片;无人机驱动装置包括机架,机架上设置有用于安装驱动电机的安装槽,安装槽的侧壁设置有两个安装孔,安装孔内活动插接有推杆,驱动电机的输出轴上设置有限位块,旋翼桨叶插接在输出轴上之后压接在限位块上,旋翼桨叶上方通过螺母进行固定限位。本发明实现了大体积桨叶旋翼机在强风环境下的正常使用。
