The invention relates to the technical field of four-rotor unmanned aerial vehicles, and discloses a four-rotor unmanned aerial vehicle protection device which comprises an unmanned aerial vehicle body, and a wing protection mechanism and a vehicle body protection mechanism are arranged in the outer side of the unmanned aerial vehicle body; the wing protection mechanism comprises a first wing plate, a second wing plate, a fixing rod, a protection wheel, an auxiliary wing plate, a spring, a fixing plate, an ultrasonic sensor and an infrared sensor; and first wing plates and second wing plates are fixedly connected to the upper ends and the lower ends of the four corners of the unmanned aerial vehicle body correspondingly. Due to the fact that an air pump and air bags are arranged at the bottom of the unmanned aerial vehicle body, after the unmanned aerial vehicle body falls, an acceleration sensor can detect that the speed in the vertical direction has a gravitational acceleration change under the gravity action in the falling process of the unmanned aerial vehicle, then a signal is sent to an industrial control computer, the first air bag and the second air bag are filled with air; after falling of the unmanned aerial vehicle, the bottom of the unmanned aerial vehicle and the bottoms of wings can be effectively buffered and protected.

    本发明涉及四旋翼无人机技术领域,公开了一种四旋翼无人机保护装置,包括无人机体,所述无人机体外侧设置有机翼防护机构和机体防护机构;所述机翼防护机构包括第一机翼板、第二机翼板、固定杆、防护轮、副机翼板、弹簧、固定板、超声波传感器和红外线传感器;所述无人机体四角上下两端分别固定连接有第一机翼板和第二机翼板。本发明由于在无人机体底部设置气泵和气囊,当无人机体坠落后,加速度传感器会检测到无人机坠落过程中受重力作用,垂直方向速度会有一个重力加速度变化,然后将信号发送给工控电脑,将第一气囊和第二气囊充满气,在无人机坠落后,能够有效对无人机底部和机翼底部进行缓冲防护。
