The invention belongs to the technical field of unmanned aerial vehicles, and particularly relates to a novel multi-rotor folding unmanned aerial vehicle. The novel multi-rotor folding unmanned aerial vehicle comprises unmanned aerial vehicle bodies, unmanned aerial vehicle wings are fixedly connected with the upper surfaces of the two unmanned aerial vehicle bodies, and spiral columns are fixedly connected with the upper surfaces of the two ends of the unmanned aerial vehicle wings. According to the multi-rotor folding unmanned aerial vehicle, the inner ring of a bearing is fixedly connected with a screw rod, a folding device is arranged on the upper surface of the screw rod and comprises a screw head, and the bottom of the screw head is fixedly connected with the top of the screw rod, so that the purposes that screw wings can incline when rotating and are parallel when not rotating are achieved; damage to the screw wings during retraction is prevented, and the individual screw wings can be conveniently detached, cleaned and replaced; and the problems that existing screw wings generally have a certain inclination degree, after the screw wings are folded and placed in a return groove, the surfaces of the screw wings can be possibly scratched, the use effect of the screw wings can be affected, and the screw wings are not easy to disassemble for cleaning and maintenance after being used for a long time are solved.
本发明属于无人机技术领域,尤其是一种新型多旋翼折叠式无人机,包括无人机本体,两个无人机本体的上表面固定连接有无人机机翼,无人机机翼的两端上表面均固定连接有螺旋柱。该多旋翼折叠式无人机,通过设置轴承的内圈固定连接有螺旋杆,螺旋杆的上表面设置有折叠装置,且折叠装置包括有螺旋头,螺旋头的底部与螺旋杆的顶部固定连接,达到了螺旋翼转动时可倾斜,螺旋翼不转动时平行,防止收回时导致螺旋翼损伤,且可方便将螺旋翼个体拆下清理更换的效果,解决了现有的螺旋翼一般都是有一定的倾斜度,当折叠过后放入回位槽后,可能会对螺旋翼的表面得到刮伤,会影响螺旋翼的使用效果,而且螺旋翼长时间使用,不易拆下进行清理维护的问题。
