[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0015] A dual-safety missile delivery device adapted for drones includes a remote control platform, a battery, a connecting and fixing plate, a front hoop, and a rear hoop. The battery is mounted on the drone, the upper end of the connecting and fixing plate is connected to the drone, and the lower end is provided with the front hoop and the rear hoop. The missile body is fixed to the bottom of the drone by the front hoop and the rear hoop. The front hoop ring is equipped with a safety release mechanism; the rear hoop ring is equipped with a locking safety mechanism; the safety release mechanism and the locking safety mechanism are linked together. The remote control platform includes an airborne receiver and a ground-based remote control device. The airborne receiver is connected to the locking mechanism and the deployment mechanism; it is used to receive and send instructions to the locking mechanism and the deployment mechanism. During aerial delivery, the remote control platform controls the drone to first open the locking insurance mechanism to issue the release insurance command, and then open the delivery insurance mechanism to issue the delivery command; In the event of accidental deployment, the remote control platform cannot open the deployment safety mechanism when it is locked, and will send a reset command to the locked safety mechanism to restore it.

[0016] Furthermore, it also includes a wind shield located in front of the front hoop, which is mounted under the connecting fixing plate via a hanging plate and is used to abut against the front end of the projectile.

[0017] like Figure 2 , Figure 3 , Figure 4 As shown, the insurance release mechanism includes a front adapter, a front servo motor, a front servo motor joystick, a movable connecting component, and a release lever. The front servo motor is mounted on the front collar via the front adapter, and the front servo motor joystick is movably connected to the release lever via the movable connecting component. The front adapter includes a front adapter frame and a front fixed frame. The front servo is mounted on the front fixed frame with screws. The front fixed frame is fixedly connected to the front collar via the front adapter frame and connecting screws. The movable connecting components include a ball joint rod and a connector. The front servo rocker arm is movably connected to the front servo and the ball joint rod, and the connector is movably connected to the ball joint rod and the release rod.

[0018] The locking safety mechanism includes a rear adapter, a rear servo motor, a rear servo motor rocker arm, a guide, a limit slide bar, a limit pressure bar, and a lower flap. The rear servo motor is mounted on the rear hoop via the rear adapter, and the guide is located below the rear servo motor. One end of the rear servo motor rocker arm is movably connected to the rear servo motor, and the other end is movably connected to a push rod. The other end of the push rod is movably connected to the limit slide bar, and the other end of the limit slide bar is located in the groove of the guide via the limit pressure bar. The rear adapter includes a rear adapter frame and a rear fixed frame. The rear servo is mounted on the rear fixed frame by screws. The rear fixed frame is fixedly connected to the rear hoop by screws and the rear adapter frame.

[0019] The guide is inverted U-shaped, with through holes perpendicular to the slide groove at both lower ends for the release rod to enter and exit. At the intersection of the slide groove and the through hole, the end of the limiting slide rod has a protrusion, and the release rod has a slot corresponding to the protrusion. When constrained, the protrusion at the end of the limiting slide rod is located in the slot of the release rod, and the release rod is constrained by the limiting slide rod. When released, the limiting slide rod slides forward in the slide groove in the guide, the protrusion at the end of the limiting slide rod disengages from the slot of the release rod, and the release rod is no longer constrained by the limiting slide rod. One end of the lower flap is hinged to the rear hoop, and the other end passes through the lower end of the U-shaped guide and overlaps the release lever.

[0020] Furthermore, the lower flap is provided with an arc-shaped mounting groove, the size of which is adapted to projectiles with a diameter of 80-120 mm. By replacing different lower flaps, projectiles of different calibers can be installed and deployed. Before loading, first connect and fix the delivery device to the UAV, then open the locking safety mechanism and the delivery safety mechanism in sequence. Place the bomb to be delivered horizontally in the middle of the slots of the front and rear rings, with the front end of the bomb against the groove of the wind shield. Cover the flap, and reset the delivery safety mechanism first, then reset the locking safety mechanism.

[0021] The dispensing method of the dispensing device of the present invention comprises the following steps: S1. Press the battery switch on the drone to power on the delivery device. The drone will take off and hover over the designated target. S2. The remote control platform sends a "release safety command" to open the locking safety mechanism. After the rear servo motor is started, it drives the rear servo motor rocker arm to rotate 90 degrees. The other end of the rear servo motor rocker arm drives the push rod, which pushes the limit slide rod to slide forward in the groove on the guide. The protrusion at the end of the limit slide rod disengages from the release lever slot, and the release lever loses the constraint of the limit slide rod. S3. The remote control platform sends a "deployment command" to open the deployment safety mechanism. After the front servo motor is started, it drives the front servo motor rocker arm to rotate. The front servo motor rocker arm drives the ball joint rod and the connector in sequence. The connector drives the deployment rod to move backward. The deployment rod disengages from the through holes at the two lower ends of the U-shape in the guide. S4. After the release lever disengages from the through holes at both 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 attached to the release lever, loses its constraint. Under the influence of the projectile's own weight, the projectile disengages from the constraints of the front hoop, rear hoop, and lower flap, thus completing the release task.

[0022] When the drone fails to reach the designated target area, and the remote control platform accidentally opens the locking safety mechanism, Y1. After the rear servo motor is accidentally started, the rear servo motor joystick is driven to rotate 90 degrees. The rear servo motor joystick drives the limit slide rod to slide forward in the groove on the guide through the push rod. The protrusion at the end of the limit slide rod disengages from the slot of the release lever, and the release lever is no longer constrained by the limit slide rod. Y2, The remote control platform terminates the "deployment command"; Y3. After the remote control platform sends a "reset command", the locking safety mechanism activates the rear servo motor. The rear servo motor drives the rear servo motor rocker arm to rotate 90 degrees in the reverse direction to reset. The rear servo motor rocker arm drives the limit slide rod to slide backward in the slide groove on the guide through the push rod. The protrusion at the end of the limit slide rod retracts back into the slot of the release lever, and the release lever is once again constrained by the limit slide rod. Y4. The drones will continue to fly and deploy according to normal procedures; When a drone has sent a "release command" before reaching the designated target airspace, the remote control platform may delay opening the locking safety mechanism or suspend the "deployment command" until it reaches the designated airspace.
