The invention discloses an anti-falling damage protection type unmanned aerial vehicle and belongs to the field of unmanned aerial vehicles. Variable protection parts are additionally arranged on the two sides of the bottom end of a vehicle body, each variable protection part is composed of an operation box, a fixing frame, a hollow cylinder, protection bag cloth and an intelligent rotating part, in the normal state, the intelligent rotating parts are stored at the bottom end of a rotating rod, and under the emergency situation of air crash, the intelligent rotating parts are stored at the bottom end of the rotating rod; the intelligent rotating part rotates downwards and enables the protective bag cloth to extend out of the hollow cylinder, meanwhile, the hydrogen supply tank supplies hydrogen into the protective bag cloth through cooperation of the first gas pipe and the intelligent rotating part, so that the pair of protective bag cloth is expanded in the traction extending process, and during landing, the protective bag cloth is expanded. A pair of protective bag cloth extending outwards in an arc shape can play a good role in supporting and buffering the bottom end of the machine body, even if the machine body inclines towards one side, the protective bag cloth can also resist most impact force, meanwhile, hydrogen gas is introduced into the floating supporting ball, and the falling damage degree is effectively reduced in cooperation with the floating supporting ball with the floating supporting function.

    本发明公开了一种防坠损防护型无人机,属于无人机领域,通过在机体底端两侧增设可变防护件,可变防护件由操作箱、固定架、中空筒、防护囊布以及智能转动件组成,在正常状态下,智能转动件收纳于转动杆底端,在发生坠机紧急情况下时,智能转动件向下转动并将防护囊布从中空筒内伸展出,与此同时,氢气供给罐利用第一气管与智能转动件配合向防护囊布内提供氢气,使得一对防护囊布在被牵引伸展过程中膨胀,在着陆时,一对向外弧形伸展的防护囊布能给机体底端起到很好的支撑缓冲作用,即使机体向一侧倾斜,防护囊布也能抵抗大部分的冲击力,同时浮撑球内同样被导入氢气体,配合具有浮撑作用的浮撑球,有效降低坠损程度。
