The invention discloses a falling protection device for an unmanned aerial vehicle, and relates to the technical field of unmanned aerial vehicles. The problem that a device is damaged if bounce is generated is solved. The device specifically comprises a machine body, a placement chamber is fixed to the outer wall of the bottom of the machine body through screws, four placement grooves are formedin the side wall of the placement chamber, airbags are placed on the inner walls of the placement grooves, a buffer chamber is arranged on the inner wall of the placement chamber, supporting columns are arranged on the inner wall of the buffer chamber, and impact columns are welded to the outer walls of one sides of the supporting columns. Through the arrangement of the placement chamber, when a gravity detector detects that the device vertically falls, the controller is operated to open the airbags, then the airbags can form a circular ring around the placement chamber to protect the bottom of the machine body, and when the machine body makes contact with the ground, the airbags are impacted and then a connecting circular plate makes contact with the ground and the second spring is compressed, at the moment, an impact rod rushes into the soil; and if the device rebounds, elastic claw hooks on the impact column can grab the ground to generate reverse acting force, so that the situationthat the device is damaged due to the fact that the rebound amplitude of the device is too large is prevented.

    本发明公开了一种无人机用坠落保护装置,涉及无人机技术领域;为了解决若产生反弹会损坏装置的问题;该设备具体包括机身,所述机身底部外壁通过螺钉固定有放置室,放置室侧壁开有四个放置槽,放置槽内壁放置有气囊,放置室内壁设置有缓冲室,缓冲室内壁设置有支撑柱,支撑柱一侧外壁焊接有冲击柱。本发明通过设置有放置室,重力检测器在检测到装置垂直坠落时,会操纵控制器将气囊打开,然后气囊会围绕放置室形成一个圆环,对机身底部进行保护,在接触地面时,气囊受到冲击,然后连接圆板接触地面,压缩弹簧二,此时冲击杆会冲进土壤里,若装置反弹,冲击柱上的弹性抓钩会抓取地面,产生反向作用力,防止装置反弹幅度过大造成装置损坏。
