The invention discloses a parachute ejecting device and an unmanned aerial vehicle, and relates to the technical field of aircrafts, the parachute ejecting device comprises a seat body, a piston and a parachute pack, the seat body is provided with a containing cavity, a parachute outlet and an air inlet, and the parachute outlet and the air inlet are located in the two opposite sides of the containing cavity and communicate with each other. The piston is connected to the cavity wall of the containing cavity in a sliding mode and divides the containing cavity into an inflation cavity and an umbrella cavity, and the umbrella cavity is communicated with the umbrella outlet. The umbrella bag is located in the umbrella cavity. The parachute ejection device provided by the invention can be mounted on the unmanned aerial vehicle to assist the unmanned aerial vehicle in safe landing. The air inlet of the seat body can be inflated and pressurized by high-temperature air, so that the inflation cavity drives the piston and the parachute pack to slide towards the parachute outlet, the piston and the parachute pack fly out of the parachute outlet together, and the parachute pack is opened under the action of airflow to assist landing of the unmanned aerial vehicle. Compared with the prior art, the parachute pack is isolated from high-temperature gas through the piston, the parachute pack can be prevented from being burnt by the high-temperature gas, and the parachute pack can be protected.
本发明公开了一种弹伞装置及无人机,涉及飞行器技术领域,弹伞装置包括座体、活塞和伞包,座体开设有容置腔、出伞口和进气口,所述出伞口和所述进气口位于所述容置腔的相对两侧且相互连通。活塞滑动连接于所述容置腔的腔壁并将所述容置腔隔成充气腔和伞腔,所述伞腔连通所述出伞口。伞包位于所述伞腔。本发明提供的弹伞装置,可安装于无人机,以辅助无人机安全降落。座体的进气口可以被高温气体充气加压,以使充气腔驱使活塞连同伞包朝向出伞口滑动,活塞与伞包一起从出伞口飞出,伞包在气流的作用下打开以辅助无人机降落。相较于现有技术,本发明是通过活塞将伞包与高温气体隔离,可避免高温气体灼烧伞包,有利于对伞包起防护作用。
