[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1-4 , the present invention provides a technical solution:

[0026] A new type of automatic delivery device includes a mounting plate 1; a semi-circular notch is provided on the mounting plate 1, and a rocker arm 3 is rotatably connected to the front surface of the mounting plate 1. The rocker arm 3 is divided into a long handle end and a semi-circular end, and its long handle end is rotatably connected to the mounting plate 1; a flight control servo 2 is installed on the front surface of the mounting plate 1, and a straight groove handle is fixedly connected to the output shaft of the flight control servo 2. A rotating shaft is provided on the long handle end of the rocker arm 3, and the rotating shaft is slidably connected in the straight groove handle. There are two flight control servos 2 and rocker arms 3, which are symmetrically arranged with the left-right central axis of the mounting plate 1 as the axis of symmetry.

[0027] It also includes an auxiliary mounting plate 4 and a mounting plate 6. A tail mounting sleeve 5 is installed on the auxiliary mounting plate 4. The number and position of the tail mounting sleeve 5 are adapted to the circle formed after the rocker arm 3 and the mounting plate 1 are closed. The auxiliary mounting plate 4 and the tail mounting sleeve 5 are connected by a pin 14. The mounting plate 1 and the auxiliary mounting plate 4 are respectively slidably connected to the front and back surfaces of the mounting plate 6. Rack teeth 8 and slots 9 are provided on both the mounting plate 1 and the auxiliary mounting plate 4. The rack teeth 8 and slots 9 are both L-shaped, and the rack teeth 8 and slots 9 on the mounting plate 1 and the auxiliary mounting plate 4 are arranged in the opposite direction.

[0028] During mounting, the object to be delivered is placed between the semi-circular ends of the rocker arm 3 and gradually enters the semi-circular notch of the mounting plate 1, and the tail end is placed in the tail mounting sleeve 5. By rotating the knob 11, the gear 10 is driven to rotate. The gear 10 meshes with the rack teeth 8 on both the mounting plate 1 and the auxiliary mounting plate 4 at the same time, thereby pushing the mounting plate 1 and the auxiliary mounting plate 4 to slide towards each other, gradually reducing the distance between the two. When the mounting plate 1 and the auxiliary mounting plate 4 are close to each other, the semi-circular end of the rocker arm 3 gradually enters the semi-circular notch of the mounting plate 1 until the two are completely closed to form a complete circular structure.

[0029] During delivery, the rotation of the rocker arm 3 is controlled by the flight control servo 2, so that the semi-circular end of the rocker arm 3 moves out of the semi-circular notch of the mounting plate 1, thereby opening the closed circular structure, causing the front end of the object to be delivered to fall off, driving the tail end placed in the tail mounting sleeve 5 to fall off together, and enabling the object to be delivered.

[0030] The mounting plate 1, the rocker arm 3, and the auxiliary mounting plate 4 are processed by cutting carbon fiber plates, and the structures of the tail mounting sleeve 5 and the mounting plate 6 are processed by 3D printing.

[0031] The mounting plate 1, the rocker arm 3, and the auxiliary mounting plate 4 processed by cutting carbon fiber plates, and the tail mounting sleeve 5 and the mounting plate 6 processed by 3D printing make the overall structure lightweight, reduce the weight of the device, facilitate carrying and installation, reduce the load of the drone, and have little impact on its flight performance.

[0032] An installation ring 7 is provided on the top surface of the mounting plate 6. There are four installation rings 7, which are respectively arranged at the four corners of the top surface of the mounting plate 6. The installation ring 7 is strip-shaped, and a strip-shaped installation hole is opened thereon.

[0033] The installation rings 7 at the four corners enable the mounting plate 6 to be fixed to the four corners of the bottom end of the drone, making the connection more stable. The strip-shaped installation holes provide a certain adjustable space for the installation and drilling positions, making the installation of this device more convenient.

[0034] Further, referring to Figures 1-4 , a gear 10 is rotatably connected in the mounting plate 6. The gear 10 meshes with two racks 8 at the same time. The bottom surface of the gear 10 is connected with a knob 11. The knob 11 passes through the bottom surface of the mounting plate 6 and is formed below the mounting plate 6. A top ring 12 is arranged below the gear 10. A socket 13 is opened on the bottom surface of the gear 10. A plug pin 14 is slidably connected in the top ring 12. The plug pin 14 is adapted to the socket 13. A spring 15 is arranged between the plug pin 14 and the mounting plate 6.

[0035] By adopting the above design, in the initial state, under the action of the spring 15, the plug pin 14 remains in the top ring 12, and its tip is inserted into the socket 13 on the bottom surface of the gear 10, thereby locking the gear 10 to prevent it from rotating freely. At this time, the mounting plate 1 and the auxiliary mounting plate 4 are respectively located on the front and back sides of the mounting plate 6 and are in the maximum opening distance state.

[0036] When adjusting the positions of the mounting plate 1 and the auxiliary mounting plate 4, the gear 10 can be unlocked by manually pulling down the plug pin 14. When the plug pin 14 is subjected to an external force, it compresses the spring 15 and slides out of the socket 13, thereby releasing the lock on the gear 10.

[0037] After the gear 10 is unlocked, the knob 11 connected to the bottom surface of the gear 10 can be rotated to drive the gear 10 to rotate in the mounting plate 6. Since the gear 10 meshes with the two racks 8 on the mounting plate 1 and the auxiliary mounting plate 4 at the same time, the rotation of the gear 10 will push the two racks 8 to move towards or away from each other, thereby driving the mounting plate 1 and the auxiliary mounting plate 4 to slide, so as to adjust the distance between them.

[0038] When the mounting plate 1 and the auxiliary mounting plate 4 reach the required positions, the bolt 14 is loosened, and the spring 15 will push the bolt 14 to re-insert into the socket 13 of the gear 10, locking the gear 10 to prevent it from rotating further, thereby fixing the positions of the mounting plate 1 and the auxiliary mounting plate 4.

[0039] Through the above design, the distance between the mounting plate 1 and the auxiliary mounting plate 4 in this device can be adjusted, so that this device can mount items to be hung with any length within a certain range, further improving the practicality of this device.

[0040] Working principle:

[0041] In the initial state, the mounting plate 1 and the auxiliary mounting plate 4 are respectively slidably connected to the front and back sides of the mounting plate 6, and both are in the maximum open distance state. At this time, the long handle end of the rocker arm 3 is connected to the straight groove handle, and the semi-circular end of the rocker arm 3 is not closed with the semi-circular notch of the mounting plate 1.

[0042] During mounting, the object to be dropped is placed between the semi-circular end of the rocker arm 3 gradually entering the semi-circular notch of the mounting plate 1, and the tail end is placed in the tail mounting sleeve 5. By rotating the knob 11 to drive the gear 10 to rotate, the gear 10 meshes with the racks 8 on the mounting plate 1 and the auxiliary mounting plate 4 at the same time, thereby pushing the mounting plate 1 and the auxiliary mounting plate 4 to slide towards each other, gradually reducing the distance between the two. When the mounting plate 1 and the auxiliary mounting plate 4 are close, the semi-circular end of the rocker arm 3 gradually enters the semi-circular notch of the mounting plate 1 until the two are completely closed, forming a complete circular structure.

[0043] During dropping, the rotation of the rocker arm 3 is controlled by the flight control servo 2, so that the semi-circular end of the rocker arm 3 moves out of the semi-circular notch of the mounting plate 1, thereby opening the closed circular structure, causing the front end of the object to be dropped to fall off, driving the tail end placed in the tail mounting sleeve 5 to fall off together, and enabling the object to be dropped.
