The invention discloses an unmanned aerial vehicle ejection locking and releasing device and a tackle, the ejection locking and releasing device comprises a locking stop arm, a pre-tightening spring, a swing mechanism and a reset mechanism, the locking stop arm is connected with the swing mechanism and can swing along with the swing mechanism so as to be switched between a locking state and an unlocking state, the pre-tightening spring is connected with the locking stop arm and the swing mechanism to provide pre-tightening force for keeping the locking stop arm and the swing mechanism in a locking state; in the locking state, the locking stop arm and the swing mechanism are kept at the locking position under the action of pre-tightening force, and the reset mechanism shrinks under the pressing of the swing mechanism; in the unlocking state, the swing mechanism can swing under the effect of ejection force and drive the locking stop arm to swing from the locking position to the unlocking position, and the reset mechanism abuts against the swing mechanism so that the locking stop arm and the swing mechanism can be kept at the unlocking position. According to the invention, rapid resetting between the locking state and the unlocking state and locking and releasing of an unmanned aerial vehicle can be realized.
本发明公开了一种无人机弹射闭锁释放装置及滑车,弹射闭锁释放装置包括闭锁挡臂、预紧弹簧、摆动机构和复位机构,闭锁挡臂与摆动机构连接并能随摆动机构摆动以在锁定状态和解锁状态间切换,预紧弹簧与闭锁挡臂和摆动机构连接,用于提供保持闭锁挡臂和摆动机构在锁定状态的预紧力;其中,在锁定状态闭锁挡臂和摆动机构在预紧力作用下保持在锁定位置,复位机构在摆动机构的抵压下收缩;在解锁状态摆动机构能够在弹射力作用下摆动并带动闭锁挡臂从锁定位置摆动至解锁位置,复位机构抵挡摆动机构以保持闭锁挡臂和摆动机构在解锁位置。本发明可实现锁定和解锁状态间的快速复位以及无人机的闭锁释放。
