[0029] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0030] This utility model discloses a drone dropping mechanism.

[0031] This utility model provides, for example Figures 1-7The unmanned aerial vehicle throwing mechanism shown includes a supporting plate 1 and a support plate 2 fixed on the top of the supporting plate 1, the top of the support plate 2 is fixed with a top plate 3, the bottom of the top plate 3 is fixed with two symmetrically arranged mounting plates 4, the inside of the supporting plate 1 is provided with a placing hole 5, the bottom of the supporting plate 1 is fixed with a vertical rod 6, the rod wall of the vertical rod 6 is rotatably sleeved with a baffle 7, the baffle 7 is in contact with the bottom of the supporting plate 1 and the placing hole 5, the bottom of the top plate 3 is fixed with an elastic telescopic rod 19, the bottom of the elastic telescopic rod 19 is fixed with a fixed rod 20, the bottom of the fixed rod 20 is fixed with a limiting pressing plate 21, the bottom of the limiting pressing plate 21 is fixed with a side plate 22, the outer side of the side plate 22 is slidably sleeved with an arc-shaped baffle 23, the top of the arc-shaped baffle 23 is fixed with a rotating frame 24, the upper end of the rotating frame 24 is rotatably sleeved on the outer side of the fixed rod 20, the rod wall of the fixed rod 20 is sleeved with a second torsion spring 25, the two ends of the second torsion spring 25 are fixedly connected with the fixed rod 20 and the rotating frame 24 respectively, and the side of the side plate 22 is provided with a strip-shaped slot 26 matched with the pull rod 8.

[0032] The inside of the supporting plate 1 is provided with a sliding pulling mechanism, and the sliding pulling mechanism is provided with a pull rod 8, the sliding pulling mechanism includes a cross rod 9, the inside of the supporting plate 1 is provided with a strip-shaped hole 10, the cross rod 9 is fixed in the strip-shaped hole 10 and slidably penetrates the inside of the pull rod 8, the rod wall of the cross rod 9 is sleeved with a spring 11, and the two ends of the spring 11 are fixedly connected with the cross rod 9 and the pull rod 8 respectively.

[0033] When placing the object to be dropped, the arc-shaped baffle 23 can be rotated first, causing the rotating frame 24 to rotate on the fixed rod 20, and opening one side of the side plate 22. At this time, objects such as grenades can be placed inside the side plate 22, with the bottom set in the placement hole 5. The grenade will first be squeezed by the elastic telescopic rod 19 and the limiting pressure plate 21 to determine its longitudinal position. Then, under the torque recovery of the second torsion spring 25, the arc-shaped baffle 23 moves back to its original position, which, together with the side plate 22, can limit the front, back, left, and right movements of the grenade, preventing the object from shaking or moving upwards during the flight of the drone. At the same time, the spring 11 in the sliding pull mechanism is in its natural state, which can engage the bolt of the grenade or other object located in the placement hole 5, making it easy to quickly complete the bolt removal work when the grenade is dropped. At the same time, the design of the strip groove 26 The baffle 7 is positioned to provide good space for the bolt and lever 8 of the grenade, preparing for subsequent coordination with the opening and dropping mechanism. At the same time, under the action of the first torsion spring 15, the baffle 7 fits tightly against the bottom of the support plate 1 and the placement hole 5, providing support and limiting for the object. When the grenade needs to be dropped, the baffle 7 can be driven to rotate, so that the baffle 7 slowly opens the placement hole 5. During the rotation of the baffle 7, the baffle 7 pushes the lever 8, so that the lever 8 pulls the safety bolt of the grenade laterally. As the safety bolt falls off, the baffle 7 fully opens the placement hole 5, allowing the grenade to fall stably and be dropped. With the cooperation of the arc-shaped baffle 23 and the side plate 22, after the bolt moves away from the grenade, the grenade's grip is still restricted and cannot be opened. It will only spring open after the grenade falls, ensuring the safety of the grenade drop.

[0034] To achieve the dropping function, such as Figures 1-5 As shown, the outer wall of the support plate 1 is provided with an opening and closing dropping mechanism. The opening and closing dropping mechanism is used to drive the baffle 7 to rotate and push the pull rod 8. The opening and closing dropping mechanism includes a control motor 12.

The bottom of the baffle 7 is fixedly provided with an external gear ring 14, which is configured to cooperate with the sector gear 13. The rod wall of the vertical rod 6 is sleeved with a first torsion spring 15. The two ends of the first torsion spring 15 are fixedly connected to the vertical rod 6 and the support plate 1, respectively.

[0035] When the object needs to be thrown, the battery compartment 16 supplies power to the control motor 12, the control motor 12 is started, the output shaft drives the sector gear 13 to rotate, the sector gear 13 is meshed with the outer gear ring 14 at the bottom of the baffle 7, thereby driving the baffle 7 to rotate around the vertical rod 6, at this time the first torsional spring 15 is twisted, in the process of rotating the baffle 7, the pull rod 8 is pushed to slide along the horizontal rod 9, the spring 11 is compressed, with the rotation of the baffle 7, the supporting surface of the object gradually decreases, until the object loses support and begins to fall, after the control motor 12 stops working, the baffle 7 is automatically reset under the action of the first torsional spring 15, preparing for the next throwing, at the same time, the pull rod 8 is also reset under the elastic force of the spring 11.

[0036] In order to ensure the throwing accuracy, as shown in the drawings, Figures 1-5 The outer wall of the battery compartment 16 is fixedly provided with a single-chip microcomputer 17, and the outer wall of the supporting plate 1 is fixedly provided with a monitoring camera 18, the single-chip microcomputer 17 is electrically matched with the monitoring camera 18 and the control motor 12, and the control motor 12 can adopt a micro motor.
