The invention provides a guide type parachute ejection device, particularly relates to the technical field of unmanned aerial vehicle parachuting. Through a parachute bin shell, a parachute bin partition plate is arranged in the parachute bin, a launch guide tube is arranged on the parachute bin shell, a launch guide rod is arranged in the launch guide tube, a gas generator is arranged below the parachute bin partition plate, the gas generator is communicated with the launch guide tube, parachute ropes are arranged on the parachute bin partition plate, the parachute ropes are connected with aparachute, and the launch guide rod is arranged at the joint of the parachute ropes and the parachute. The device solves the problem that parachute opening is unstable when a current unmanned aerial vehicle uses a parachute; the technical effects that a large amount of gas generated by a gas generator enters a launching guide pipe, the gas pressure instantaneously reaches a critical value, a launching guide rod is pushed to be ejected outwards, and a parachute is driven to be opened in the ejection process are achieved, and the safety of an unmanned aerial vehicle parachute landing system andthe risk avoiding capacity in a sudden environment are improved.

    本发明提供一种引导式降落伞弹射装置,具体涉及无人机伞降技术领域,通过采用伞仓外壳,其内部设置有伞仓隔板,伞仓外壳上设置有发射引导管,发射引导管内部设置有发射引导杆,伞仓隔板下方设置有气体发生器,气体发生器和发射引导管连通,伞仓隔板上设置有伞绳,伞绳连接降落伞,发射引导杆设置于伞绳和降落伞的连接处的技术方案。该装置解决了当前无人机使用降落伞时开伞不稳定,延迟高的问题,通过气体发生器产生大量气体进入到发射引导管中,气压瞬间达到临界值,推动发射引导杆向外弹射,弹射过程中带动降落伞打开的技术效果,提高了无人机伞降系统的安全性和突发环境中避险的能力。
