The invention belongs to the technical field of unmanned aerial vehicles, and particularly relates to an anti-collision unmanned aerial vehicle which comprises a vehicle body, a supporting arm and a paddle and further comprises a fixing ring fixedly arranged at the tail end of the supporting arm, and the fixing ring is located outside the paddle. By arranging the anti-collision rubber ring, the arc-shaped flexible strain sheet and the anti-collision air bag, an effective protection system from low-speed collision to high-speed collision is formed, the anti-collision rubber ring buffers during low-speed collision, the arc-shaped flexible strain sheet triggers the anti-collision air bag to pop up to provide secondary protection during violent collision, and the damage risk of the unmanned aerial vehicle is greatly reduced; meanwhile, through cooperation of a photoresistor and an illumination intensity detection mechanism, the influence of illumination on the anti-collision rubber ring can be monitored in real time, aged parts can be conveniently replaced in time, and the protection performance is maintained; in addition, during collision, the balance mechanism can keep the fuselage horizontal, fuselage unbalance damage caused by collision is reduced, and safe and stable operation and normal operation of the unmanned aerial vehicle in a complex flight environment are powerfully guaranteed.
本发明属于无人机技术领域,尤其是涉及一种防撞无人机,包括机身、支臂和桨叶,还包括:固定环,固定设置于支臂的末端,且固定环位于桨叶的外部。本发明通过设置防撞橡胶圈、弧形柔性应变薄片和防撞气囊,形成了从低速到高速碰撞的有效防护体系,防撞橡胶圈在低速碰撞时缓冲,猛烈撞击时弧形柔性应变薄片触发防撞气囊弹出提供二次保护,大大降低了无人机受损风险;同时,利用光敏电阻和光照强度检测机构的协同,能够实时监测光照对防撞橡胶圈的影响,便于及时更换老化部件,维持防护性能;此外,在碰撞时平衡机构可使机身保持水平,减少因碰撞导致的机身失衡损坏,有力保障了无人机在复杂飞行环境下的安全稳定运行和正常作业。
