The invention relates to the technical field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle piston engine braking device which comprises a braking device body, and the braking device body comprises a power source; the bearing bracket is detachably connected with the power source; and the brake part penetrates through the bearing support and is provided with a follow-up unit matched with the power source, and the power source can drive the follow-up unit to move so that the brake part can directionally move relative to the bearing support. When the unmanned aerial vehicle is landed by opening a parachute or colliding with a net and a rope, landing failure caused by winding and cutting off a parachute rope or a net rope by a windmill effect or an inertia high-speed rotating propeller is prevented, and potential safety hazards to personnel and the unmanned aerial vehicle caused by collision and disassembly of the high-speed rotating propeller are prevented; aiming at the condition that the engine of the unmanned aerial vehicle is out of control during flight or ground work, the unmanned aerial vehicle can be braked to lose power to land or stop working, additional loss caused by out-of-control flight of the unmanned aerial vehicle is prevented, and the safety of personnel and the unmanned aerial vehicle is ensured.

    本发明涉及无人机技术领域,具体是一种无人飞行器活塞发动机制动装置,包括制动装置本体,制动装置本体包括动力源;轴承支架,与动力源可拆卸连接;刹车件,贯穿轴承支架,且形成有与动力源适配的随动单元,动力源能够驱动随动单元运动以使刹车件相对轴承支架定向移动。本发明针对无人机开伞降落或撞网、撞绳降落时,防止风车效应或惯性高速旋转的螺旋桨缠绕切断伞绳或网绳造成降落失败,防止高速旋转螺旋桨碰撞解体对人员和无人机带来安全隐患;本发明针对无人机发动机在飞行途中或地面工作中失控的情况,可以采用本发明制动使无人机失去动力降落或停止工作,防止无人机失控飞行工作造成额外损失,保证人员和无人机的安全。
