The invention discloses a folding multi-rotor unmanned aerial vehicle, belongs to the technical field of aircrafts, and provides a four-rotor unmanned aerial vehicle with vertically staggered rotor discs, which can give consideration to simplicity and reliability of multiple rotors and small-size constraint of coaxial double rotors. The four rotors are arranged on the surface of the unmanned aerial vehicle body, and every two rotors are staggered in the diagonal perpendicular direction, so that the situation that the four rotors interfere with each other when folded and stored on the same horizontal plane is avoided, and diagonal rotor discs are located on two different horizontal planes after unfolding; or the lengths of the diagonal rotors are equal, and the lengths of the adjacent rotors are different, so that the staggered arrangement of the rotor discs on the same horizontal plane is realized, and the motors are arranged in a staggered manner without interference after being folded and stored.

    本发明公开了一种折叠多旋翼无人机,属于飞行器技术领域,提出了旋翼桨盘垂直交错式的四旋翼无人机,可以兼顾多旋翼的简单可靠和共轴双旋翼的小尺寸约束。本发明通过在无人机机身表面布置四个旋翼,其中两两旋翼对角线垂直方向错开,从而避免四个旋翼在同一水平上折叠收纳时发生干涉,展开后对角线旋翼桨盘分别在两个不同的水平面上;或者对角旋翼长度相等,相邻旋翼长度不同,从而实现旋翼桨盘在同一水平面上错位布置,在折叠收纳后电机得以错位布置而不发生干涉。
