The invention discloses a coaxial dual-rotor unmanned aerial vehicle. The coaxial dual-rotor unmanned aerial vehicle comprises an upper rotor fixing assembly, a lower rotor fixing assembly, a coaxial motor, a nose tilting mechanism and a PCBA which are coaxially arranged, the outer side of the upper rotor wing fixing assembly and the outer side of the lower rotor wing fixing assembly are each symmetrically provided with a set of blades. The lower rotor wing fixing assembly sleeves the top of the coaxial motor and is connected with an output shaft of the coaxial motor, and the other output shaft of the coaxial motor penetrates through the lower rotor wing fixing assembly and is used for mounting the upper rotor wing fixing assembly; when the coaxial motor rotates, the upper rotor wing fixing assembly, the lower rotor wing fixing assembly and the upper blade paddles are driven to rotate in opposite directions; the coaxial motor is fixedly installed above the machine head inclining mechanism, and the machine head inclining mechanism drives the coaxial motor and components above the coaxial motor to incline in different directions. According to the unmanned aerial vehicle, the coaxial motor and the components above the coaxial motor are driven by the nose tilting mechanism to tilt in different directions, so that the precise control of the tilt angle is realized, and the flight direction of the unmanned aerial vehicle can be precisely and sensitively controlled.

    本发明公开了一种共轴双旋翼无人机,包括共轴设置的上旋翼固定组件、下旋翼固定组件、共轴电机、机头倾斜机构及PCBA;所述上旋翼固定组件外侧、下旋翼固定组件外侧分别对称设置一组叶浆;所述下旋翼固定组件套设于共轴电机顶部并与其一输出轴连接,共轴电机的另一输出轴穿过下旋翼固定组件,用以安装上旋翼固定组件;所述共轴电机转动时,驱动上旋翼固定组件和下旋翼固定组件及其上叶浆反向旋转;所述共轴电机固定安装于机头倾斜机构上方,机头倾斜机构驱动共轴电机及其上方组件向不同方向倾斜。本发明通过机头倾斜机构驱动共轴电机及其上方组件向不同方向倾斜,实现倾斜角度的精确控制,从而可精确、灵敏地控制无人机的飞行方向。
