Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a UAV airdrop controller and a UAV. Background Technology

[0002] In recent years, drone technology has developed rapidly, enabling drones to be widely used in many fields. In particular, when transporting goods in complex geographical environments, traditional manual transportation methods are greatly limited, while drones can give full play to their flexibility and mobility.

[0003] Existing drone transportation uses a high-altitude automatic delivery device disclosed in announcement number CN215794454U. The device uses a controller to drive a pin to insert into a pin hole and engage. The claw-type structure can hold various types of projectiles. The mechanical pin fixation can prevent accidental slippage. The device is controlled by remote control to automatically complete the airdrop. However, the clamp-type structure severely limits the amount of materials that the drone can carry. Moreover, the fixation and delivery methods for materials are limited, allowing materials to be delivered from only one location. Furthermore, there is a lack of storage and management of materials on the drone. During the delivery process, the drone is prone to imbalance due to a shift in the center of gravity, lacking balance and stability. Even when tilted, it is difficult to ensure the accuracy and safety of material delivery. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Reference Figures 1-5 A drone airdrop controller includes two sets of symmetrical support brackets 1. The lower ends of the two sets of support brackets 1 are integrally connected to load plates 2. The load plates 2 are horizontally set and used to place and support airdropped supplies.

[0029] Two sets of symmetrical front-to-back limiting and closing mechanisms 3 are fixedly installed between the two sets of support brackets 1. Two sets of symmetrical front-to-back stop mechanisms 4 are fixedly installed on the load-bearing plate 2. The position between the limiting and closing mechanisms 3 and the stop mechanisms 4 is used for vertical placement of airdropped supplies. Please refer to the appendix of the instruction manual for details. Figure 3 It should be noted that:

[0030] On one hand, the limiting and closing mechanism 3 includes a closing main plate 31 fixedly connected to the support plate 12. A telescopic sub-plate 32 is slidably fitted in the closing main plate 31. A guide elongated hole 33 is opened in the closing main plate 31. A guide block 34 fixedly connected to the closing main plate 31 is slidably installed in the guide elongated hole 33. A drive turntable 35 is rotatably installed on the closing main plate 31. A first drive motor for driving the drive turntable 35 to rotate is fixedly installed on the closing main plate 31. A traction swing rod 36 is rotatably installed on the closing main plate 31, which is moved by the drive turntable 35 and drives the guide block 34 to rise and fall vertically. The traction swing rod 36 converts the circular rotation of the drive turntable 35 into the linear reciprocating movement of the guide block 34, thereby controlling the linear rise and fall of the telescopic sub-plate 32 according to the size of an airdropped material at the lowest position, ensuring that the airdropped material can be discharged through the outlet opened by the telescopic sub-plate 32.

[0031] On the other hand, the stop mechanism 4 includes a baffle 41 fixedly installed on the load plate 2. The baffle 41 and the closed main board 31 form a closed and limited enclosure of the airdropped materials. A one-way notch 42 is provided at the lower end of the baffle 41. A tensioning and opening push plate 43 is provided in the one-way notch 42, which deflects toward the telescopic sub-plate 32. The tensioning and opening push plate 43 can only tilt and open in one direction toward the limiting and closing mechanism 3 to apply pressure to the airdropped material at the lowest position, so that the airdropped material is discharged from the drone through the outlet opened by the telescopic sub-plate 32.

[0032] A conveying mechanism 5 for horizontally pushing airdropped materials is provided between the two sets of limiting and closing mechanisms 3. The conveying mechanism 5 includes a guide sleeve 51, a steering bracket 52 rotatably installed in the guide sleeve 51, a drive gear 53 rotatably installed in the steering bracket 52, and a reciprocating rack push rod 54 that meshes with the drive gear 53 and moves against the opening and closing push plate 43 is slidably installed in the steering bracket 52. The reciprocating rack push rod 54 applies pressure to the opening and closing push plate 43, and the outwardly opening opening and closing push plate 43 pushes the airdropped materials to one side of the limiting and closing mechanism 3, so that the airdropped materials are discharged through the outlet opened by the telescopic auxiliary plate 32.

[0033] The support bracket 1 includes a connecting gantry 11 that is fixedly connected to the load plate 2. A support plate 12 is fixedly installed on the connecting gantry 11. It should be noted that the connecting gantry 11 is fixedly installed at the lower end of the UAV.

[0034] One end of the traction lever 36 has a traction hole, and the drive turntable 35 is integrally connected with an eccentrically set traction bolt that is slidably fitted into the traction hole. The other end of the traction lever 36 slides through the guide block 34. During the rotation of the drive turntable 35, the traction lever 36 is driven to deflect by the traction bolt. The traction lever 36, which performs lever-like motion, drives the guide block 34 to move linearly back and forth.

[0035] A drone includes the aforementioned drone airdrop controller, with a guide sleeve 51 fixedly installed on the drone. The drone airdrop controller is used for mobile transportation by a drone towing bolt and for material delivery by the drone airdrop controller.

[0036] It should be noted that the specific models and specifications of the first and second drive motors need to be selected and determined based on the actual specifications of the device. The specific selection and calculation methods use existing technology in this field, so they will not be elaborated here.

[0037] The functional principle of this utility model can be explained through the following operation methods:

[0038] The rotation of the drive turntable 35 is controlled according to the size of a single airdropped item, causing the traction swing arm 36 to deflect, which in turn drives the telescopic sub-plate 32 to move vertically upward along the closed main plate 31 via the guide block 34.

[0039] The steering bracket 52 is controlled to rotate along the guide sleeve 51, and then the drive gear 53 is controlled to rotate, so that the reciprocating rack push rod 54 moves horizontally to apply pressure to the opening and closing push plate 43. The opening and closing push plate 43 applies pressure to an airdropped material located at the lowest position, so that the airdropped material is discharged through the telescopic auxiliary plate 32.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
