The invention relates to a rotor unmanned aerial vehicle with an emergency landing function. The rotor unmanned aerial vehicle comprises an unmanned aerial vehicle body, a plurality of vehicle arms capable of being unfolded or folded, connecting rods with the same number as the vehicle arms, a second driving mechanism and a parachute. A supporting rod is arranged on the unmanned aerial vehicle body, an upper base sliding on the supporting rod is connected with the vehicle arm through a connecting rod, and the sliding position is controlled by a second driving mechanism so that the vehicle arm can be folded inwards or unfolded outwards. A parachute is stored at the top of the unmanned aerial vehicle, the unmanned aerial vehicle is connected with an unmanned aerial vehicle body through parachute cords, and an ejection mechanism is arranged for ejecting the parachute in emergency. When the unmanned aerial vehicle is out of control, the unmanned aerial vehicle slides to a designated position along with the upper base to trigger the ejection mechanism to eject the parachute, and the landing speed of the unmanned aerial vehicle is slowed down by utilizing the parachute to hang in the air for deceleration, so that safe emergency landing is realized, and damage caused by out-of-control is effectively reduced.

    本发明涉及一种具有紧急迫降功能的旋翼无人机,包括无人机本体、多个可展开或收折的机臂、与机臂数量一致的连杆、第二驱动机构及降落伞。无人机本体上设有支撑杆,其上滑动的上部基座通过连杆与机臂连接,由第二驱动机构控制滑动位置以实现机臂向内收折或向外展开。无人机顶部收纳有降落伞,通过伞绳与无人机本体相连,并配备弹射机构用于紧急情况下弹出降落伞。当无人机失控时,随着上部基座滑动到指定位置触发弹射机构,将降落伞弹出,利用降落伞滞空减速,减缓无人机降落速度,从而实现安全紧急迫降,有效减少因失控造成的损伤。
