The invention relates to a novel foldable rotor tilting quad-rotor unmanned aerial vehicle, and mainly relates to the field of manufacturing of quad-rotor unmanned aerial vehicles. The four-rotor unmanned aerial vehicle with the tiltable transformation structure comprises a fuselage, a rotor folding module, a tiltable module, a flight control module, a brushless motor and a propeller, the fuselage is connected with the tiltable structure through a rotor folding structure, and the brushless motor and the propeller are installed on the tiltable structure. When the rotor wings of the unmanned aerial vehicle break down, the flight control module can control the diagonal rotor wing propellers relative to the broken-down rotor wings to stop rotating and fold the two rotor wing arms, gravity center shift caused by uneven stress distribution of the broken-down vehicle arms is reduced, and stability of the gravity center of the vehicle body is guaranteed.
本发明涉及一种新型可折叠旋翼倾转四旋翼无人机,主要涉及四旋翼无人机制造领域。该可倾转变结构四旋翼无人机包括机身、旋翼折叠模块、可倾转模块、飞行控制模块、无刷电机和螺旋桨,机身通过旋翼折叠结构连接可倾转结构,在可倾转结构上安装有无刷电机与螺旋桨。当无人机旋翼发生故障时,飞行控制模块可控制相对于故障旋翼的对角旋翼螺旋桨停转并将这两个旋翼臂折叠,减小了由于故障机臂受力分布不均匀而造成的重心偏移,保证机体重心的稳定。
