The airborne receiving device is connected to the locking safety mechanism and the delivery safety mechanism; it is used to receive and send instructions to the locking safety mechanism and the delivery safety mechanism; During air delivery, the remote control platform controls the drone to first open the locking safety mechanism to implement the release command, and then open the delivery safety mechanism to implement the delivery command; When the release is performed by mistake, the remote control platform cannot open the release safety mechanism when the locking safety mechanism is in the locked state, and sends a reset instruction to the locking safety mechanism to achieve reset and restoration.

[0006] Furthermore, it also includes a windshield arranged in front of the front hoop, which is arranged under the connecting fixing plate through a hanging plate and is used to abut against the front end of the projectile.

[0007] Furthermore, the launching safety mechanism includes a front transfer platform, a front servo, a front servo rocker, a movable connection component and a launching pull rod, the front servo is arranged on the front hoop through the front transfer platform, and the front servo rocker is movably connected to the launching pull rod through the movable connection component; The locking safety mechanism includes a rear transfer platform, a rear servo, a rear servo rocker, a guide, a limit slide, a limit pressure rod and a lower flap. The rear servo is arranged on the rear hoop through the rear transfer platform. The guide is arranged below the rear servo. One end of the rear servo rocker is movably connected to the rear servo, and the other end is movably connected to the push rod. The other end of the push rod is movably connected to the limit slide. The other end of the limit slide is arranged in a slide groove of the guide through the limit pressure rod.

[0010] Furthermore, an arc-shaped mounting groove is provided on the lower flap, and the size of the mounting groove is suitable for a projectile with a diameter of 80-120 mm.

[0011] A method for delivering a double-safety delivery device for a missile suitable for an unmanned aerial vehicle comprises the following steps: S1. Press the battery switch on the drone to power up the delivery device. The drone takes off and hovers over the designated target. S2. The remote control platform sends a "release command" to open the locking safety mechanism. After the rear servo is started, the rear servo rocker is driven to rotate 90 degrees. The other end of the rear servo rocker drives the push rod, which pushes the limit slide bar to slide forward in the slide groove on the guide. The end block of the limit slide bar disengages from the release rod slot, and the release rod loses the restraint of the limit slide bar. S3. The remote control platform sends a "release command" to open the release safety mechanism. After the front servo is started, the front servo rocker is driven to rotate. The front servo rocker in turn drives the ball head pull rod and the connector. The connector drives the release rod backward, and the release rod is disengaged from the through holes at the two lower ends of the U-shaped guide. S4. After the delivery rod is separated from the through holes at the two lower ends of the U-shape in the guide, the lower flap at the lower end of the U-shape of the guide, which is overlapped on the delivery rod, loses its constraint. Under the influence of the gravity of the projectile itself, the projectile is separated from the constraints of the front hoop, the rear hoop and the lower flap, thus completing the delivery mission.

[0012] Furthermore, when the UAV fails to reach the designated target and the locking safety mechanism is opened due to erroneous operation of the remote control platform, Y1. After the rear servo is started by mistake, the rear servo rocker is driven to rotate 90 degrees. The rear servo rocker drives the limit slide bar to slide forward in the slide groove on the guide through the push rod. The end block of the limit slide bar disengages from the slot of the release rod, and the release rod is no longer constrained by the limit slide bar. Y2. The remote control platform terminates the "delivery command"; Y3. After the remote control platform sends the "reset command", the locking safety mechanism activates the rear servo, which drives the rear servo rocker to rotate 90 degrees in the opposite direction to reset. The rear servo rocker drives the limit slide bar to slide backward in the slide groove on the guide via the push rod. The end of the limit slide bar retracts into the slot of the release rod, and the release rod is restrained by the limit slide bar again. Y4. The drone continues to fly and launch according to normal procedures; Furthermore, when the UAV has not reached the designated target but has sent the "release command", if the remote control platform needs to delay opening the locking safety mechanism, it can also terminate the "release command" and send the "release command" again when it reaches the designated target.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention realizes the two-step instructions of release and release during the projectile release process through the interconnected locking safety mechanism and release safety mechanism, thereby solving the safety problem of drone projectile release; 2. The present invention also solves the safety problem of drone delivery being stopped due to misoperation or requiring delivery to be terminated or delayed due to unexpected circumstances during flight through the two-step instruction termination delivery instruction and reset release instruction, as well as suspension and delayed delivery instructions.
