The invention relates to the technical field of undercarriages, and discloses a liftable undercarriage which comprises an unmanned aerial vehicle body, a single chip microcomputer is arranged in the unmanned aerial vehicle body, driving mechanisms are arranged at the four corners of the top side of the unmanned aerial vehicle body, and a rotating speed sensor is arranged on one side of each driving mechanism. And the bottom side of the rotating speed sensor is fixedly installed on the top side of the unmanned aerial vehicle body, a storage bin is fixedly installed on the top side of the unmanned aerial vehicle body, and a parachute is arranged in the storage bin. Through arrangement of the rotating speed sensor, an electromagnetic valve, a sucking pump, an air bag and the parachute, during use, when the unmanned aerial vehicle body stops running due to a fault in the flight process, the rotating speed sensor detects that the driving mechanism stops rotating, so that the single chip microcomputer controls the sucking pump and the electromagnetic valve to inflate air into the air bag and the storage bin; and the parachute is opened while the airbag expands, so that the unmanned aerial vehicle body stably falls, and the unmanned aerial vehicle body is prevented from being broken.

    本发明涉及起落架技术领域,公开了一种可升降式起落架,包括无人机本体,所述无人机本体的内部设置有单片机,所述无人机本体顶侧的四角均设置有驱动机构,所述驱动机构的一侧设置有转速传感器,所述转速传感器的底侧固定安装在无人机本体的顶侧,所述无人机本体的顶侧固定安装有收纳仓,所述收纳仓的内部设置有降落伞。本发明通过设置的转速传感器、电磁阀、抽气泵、气囊和降落伞,在使用时,当无人机本体飞行过程中发生故障停止运行时,转速传感器检测到驱动机构停止转动,从而通过单片机控制抽气泵和电磁阀,对气囊和收纳仓内充入气体,气囊膨胀的同时降落伞打开,从而使得无人机本体平稳下落,避免无人机本体摔坏。
