The present invention discloses a vector coaxial double-propeller unmanned aerial vehicle. A first rotor wing and a second rotor wing are both installed at the output end of a contra-rotating motor, and the rotating direction of the first rotor wing is opposite to the rotating direction of the second rotor wing; the shell of the contra-rotating motor is fixed to a first overturning frame, the first overturning frame is rotationally connected into a second overturning frame, the second overturning frame is rotationally connected into the upper frame, and the rotating shaft of the first overturning frame is perpendicular to the rotating shaft of the second overturning frame. A first steering engine is fixed on the second overturning frame, and the output shaft of the first steering engine isconnected with the first overturning frame through a first connecting rod mechanism; and a second steering engine is fixed to the upper frame, and the output shaft of the second steering engine is connected with the second overturning frame through a second connecting rod mechanism. The problem that an unmanned aerial vehicle cannot fly normally due to the fact that propellers of the unmanned aerial vehicle are damaged and lose balance in the prior art is solved. The unmanned aerial vehicle has the advantages of being small in size, convenient to carry, high in safety, symmetrical in reactiontorque, good in hovering effect and remarkably enhanced in stability.
本发明公开了一种矢量共轴双桨无人机,第一旋翼和第二旋翼均安装在对转电机的输出端,第一旋翼的转动方向与第二旋翼的转动方向相反;对转电机的壳体固定在第一翻转架上,第一翻转架转动连接在第二翻转架中,第二翻转架转动连接在上框架中,第一翻转架的转轴垂直于第二翻转架的转轴;第一舵机固定在第二翻转架上,第一舵机的输出轴通过第一连杆机构与第一翻转架连接;第二舵机固定在上框架上,第二舵机的输出轴通过第二连杆机构与第二翻转架连接。目的在于解决现有技术中无人机螺旋桨损坏会失去平衡而不能正常飞行的问题。效果为:体积小巧,携带方便,安全性高,反扭矩对称,悬停效果好,稳定性显著增强。
