The invention discloses an unmanned aerial vehicle automatic parachute opening mechanism with multiple triggering conditions, and particularly relates to the field of unmanned aerial vehicles, the unmanned aerial vehicle automatic parachute opening mechanism comprises an unmanned aerial vehicle body and an automatic parachute opening device, a spiral blade is detachably installed on one side of the unmanned aerial vehicle body, and the input end of the automatic parachute opening device is electrically connected with a delay signal generator; and the input end of the delay signal generator iselectrically connected with a gravity switch, a three-jaw parachute cord is detachably installed on one side of the top end of the unmanned aerial vehicle body, a main parachute cord is fixedly installed on the surface of the top end of the three-jaw parachute cord, and a main parachute body is fixedly installed on one side of the main parachute cord. By arranging the automatic parachute cutting device, the effect of low use cost is achieved, and the situation that due to the fact that the unmanned aerial vehicle lands in a gale area, once the landing point of the unmanned aerial vehicle is far away or exceeds the visual range, the unmanned aerial vehicle cannot be manually folded in time, and consequently the unmanned aerial vehicle turns over or rubs the ground, and even internal equipment of the unmanned aerial vehicle is damaged is avoided.

    本发明公开了一种多触发条件的无人机自动切伞机构,具体为无人机领域,包括无人机本体和自动切伞装置,所述无人机本体的一侧可拆卸安装有螺旋叶,所述自动切伞装置的输入端电性连接有延时信号发生器,所述延时信号发生器的输入端电性连接有重力开关,所述无人机本体顶端的一侧可拆卸安装有三爪伞绳,所述三爪伞绳顶端的表面固定安装有主伞绳,所述主伞绳的一侧固定安装有主伞本体。本发明通过设置了自动切伞装置,从而达到了使用成本低的效果,避免了因为无人机是在大风区域下进行落地的,一旦无人机落地点较远或超出了目视范围时,无法及时人工收伞,就会导致无人机翻转或者与地面摩擦,造成无人机甚至内部设备损伤的问题。
