The unmanned aerial vehicle comprises a vehicle body, a parachute cord and the recovery parachute, a parachute cabin is arranged in the vehicle body, one end of the parachute cord is connected into the parachute cabin, the other end of the parachute cord is fixedly connected with the recovery parachute, the direct throwing mechanism further comprises a throwing assembly, and the throwing assembly comprises a double-arm torsion spring, a parachute cover and a locking piece; two first torsion arms of the double-arm torsion spring are rotationally connected with the inner bottom wall of the parachute bay, two second torsion arms of the double-arm torsion spring are both in sliding connection with the parachute cover, the locking piece is arranged on one side of the top of the parachute bay and used for opening or closing the parachute cover, and when the parachute cover is closed, the recovery parachute and the parachute cord are in a first state of being stored in the parachute bay; and the two first torsion arms are located below the recovery parachute, and when the parachute cover is opened, the recovery parachute and the parachute cord are in a second state of being cast out of the parachute cabin. The problems that an effective parachute throwing assembly is not arranged in the unmanned aerial vehicle, and when the recovered parachute is taken out of a cabin, the recovered parachute is easily blown and wound on a fuselage or a propeller by longitudinal airflow from the direction of a nose to cause air crash accidents are solved.

    本发明公开了一种无人机的回收伞用直抛机构,无人机包括机体、伞绳以及回收伞,机体内设有伞舱,伞绳的一端连接于伞舱内,伞绳的另一端与回收伞固定连接,还包括抛射组件,抛射组件包括双臂扭簧、伞盖以及锁紧件,双臂扭簧的两第一扭臂与伞舱的内底壁转动连接,双臂扭簧的两第二扭臂均与伞盖滑动连接,锁紧件设于伞舱顶部的一侧,锁紧件用开启或关闭伞盖,当伞盖关闭时,回收伞和伞绳呈收纳于伞舱内的第一状态,且两第一扭臂位于回收伞的下方,当伞盖开启时,回收伞和伞绳呈抛射出伞舱外的第二状态。解决了无人机内未设有有效地抛伞组件,回收伞在出舱时,很容易被来自机头方向的纵向气流,吹袭缠绕到机身或推进器上而产生坠机事故的问题。
