Abstract

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.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicle ejection, in particular to an unmanned aerial vehicle locking release mechanism for an ejection device. Background technique [0002] UAV is a kind of unmanned aircraft controlled by radar or airborne program, mainly used for reconnaissance and surveillance, deceiving the enemy as bait, implementing interference, and attacking the ground. Compared with traditional aircraft, drones have the advantages of good concealment, low cost, simple take-off and landing, and flexible operation, and are playing an increasingly important role in military and civilian fields. [0003] In the related technology research of UAV, UAV ejection is a new type of launching method. UAV ejection refers to the use of electromagnetic thrust or pneumatic thrust to make the UAV reach the initial take-off speed. Among them, the UAV locking release technology is a difficult and high-tech technology. It is req...
