Description

Technical Field

[0001] This utility model relates to the field of drone hoisting technology, and in particular to a hybrid electric drone hoisting structure. Background Technology

[0002] Drones can be categorized by their power source into electric drones, gasoline-powered drones, and hybrid drones. Hybrid drones combine the advantages of both gasoline and electric power. Compared to pure electric drones, they overcome the drawbacks of low battery energy density and short flight time, improving the precision control of electric drive, resulting in extremely low operating costs and extended flight time, making them more suitable for fields with high endurance requirements such as power line inspection, logistics transportation, and public security and fire fighting. Compared to pure gasoline-powered drones, hybrid drones can also utilize the flexibility and cleanliness of electric drive in certain situations.

[0003] Currently, when hybrid drones need to perform lifting operations, a lifting device is usually installed under the drone to lift and transport the items to be transported. However, when the items to be lifted need to be fixed in multiple different positions, current hybrid drones cannot deliver the items stably, which reduces the working efficiency of the lifting structure of hybrid drones. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a hybrid electric unmanned aerial vehicle (UAV) hoisting structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A hybrid electric unmanned aerial vehicle (UAV) hoisting structure includes a UAV body. The lower end of the UAV body is fixedly connected to a connecting block. The upper end of the connecting block is semi-circular, and the lower end is a hollow cylinder. The inner wall of the connecting block is threaded. The lower end of the connecting block is threadedly connected to a hook. The lower end of the connecting block can also be threadedly connected to a threaded column. The lower end of the threaded column is fixedly connected to a mounting plate. The mounting plate is circular in shape.

[0006] Preferably, the lower end of the drone body is fixedly connected to two columns, the cross-sectional shape of the two columns is rectangular, the lower ends of the two columns are respectively connected to corresponding bolts through through holes, the lower end of the connecting block is in contact with the L-shaped plate, and the upper end of the hook is in contact with the L-shaped plate.

[0007] Preferably, the outer walls of the two bolts respectively penetrate the corresponding columns through through holes.

[0008] Preferably, two brackets are installed at the lower end of the drone body.

[0009] Preferably, both brackets are U-shaped, and two connectors are installed at the upper end of each bracket. The other ends of the four connectors are fixedly connected to the main body of the drone.

[0010] Preferably, the surface of the mounting plate is machined with four mounting holes, which are equidistantly distributed on the surface of the mounting plate.

[0011] Preferably, the ends of the two bolts are rotatably connected to the corresponding L-shaped plates via bearings.

[0012] The beneficial effects of this utility model are as follows: 1. By using the drone body, connecting block, hook, threaded column, and mounting plate, when multiple positions of the transported item need to be fixed, the operator loosens two bolts, causing the bolts to move the L-shaped plate away from the connecting block and hook. Then, the operator unscrews the hook, inserts the threaded column into the lower end of the connecting block, and screws the threaded column into the connecting block. Then, the bolts are rotated in the opposite direction, causing the two L-shaped plates to press against the lower end of the connecting block and threaded column, thus fixing the position of the mounting plate. Then, the rope is inserted into the mounting hole on the mounting plate, so that multiple positions of the transported item can be fixed. In this way, the mounting plate can fix multiple positions of the item, making the drone more stable when transporting items, which improves the working effect of the lifting structure of the hybrid electric drone. 2. By using bolts, columns, and L-shaped plates, after the mounting plate and hook are replaced, the L-shaped plates are pressed against the connection between the connecting block and the hook or threaded column to further fix the hook or threaded column. This also improves the working efficiency of the lifting structure of the hybrid electric UAV. Attached Figure Description

[0015] 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.

[0016] Example 1, referring to Figures 1 to 5 A hybrid electric drone hoisting structure includes a drone body 1. The lower end of the drone body 1 is fixedly connected to a connecting block 4. The upper end of the connecting block 4 is semi-circular, and the lower end is hollow cylindrical. The hollow cylindrical design facilitates the insertion of a threaded post 11 or a hook 5. The inner wall of the connecting block 4 is threaded. The lower end of the connecting block 4 is threadedly connected to the hook 5. The thread makes the hook 5 more stable. The lower end of the connecting block 4 can also be threadedly connected to the threaded post 11. The threaded post 11 can also be pressed into the connecting block 4. The lower end of the threaded post 11 is fixedly connected to a mounting plate 10. The mounting plate 10 is circular in shape, which facilitates the uniform fixing of items. When multiple positions need to be secured to the transported items, the operator loosens the two bolts 8, causing the bolts 8 to move the L-shaped plates 9 away from the connecting block 4 and the hook 5. The operator then unscrews the hook 5, inserts the threaded post 11 into the lower end of the connecting block 4, and screws the threaded post 11 into the connecting block 4. Next, the bolts 8 are rotated in the opposite direction, causing the two L-shaped plates 9 to press against the lower end of the connecting block 4 and the threaded post 11, thus securing the position of the mounting plate 10. The rope is then inserted into the mounting holes 6 on the mounting plate 10, ensuring that multiple positions of the transported items are secured. This method allows the mounting plate 10 to secure multiple positions of the items, making the drone more stable when transporting them. This improves the working efficiency of the lifting structure of the hybrid electric drone. In this embodiment, the lower end of the drone body 1 is fixedly connected to two columns 7. The cross-sectional shape of the two columns 7 is rectangular. The lower ends of the two columns 7 are threadedly connected to corresponding bolts 8 through through holes. While the bolts 8 rotate inside the columns 7, the ends of the bolts 8 move horizontally. The lower end of the connecting block 4 contacts the L-shaped plate 9, and the upper end of the hook 5 contacts the L-shaped plate 9. The L-shaped plate 9 fixes the hook 5 to prevent it from rotating and falling off the connecting block 4 during operation. The outer walls of the two bolts 8 pass through the corresponding columns 7 through through holes. Two brackets 2 are installed at the lower end of the drone body 1. The brackets 2 support the drone body... The drone body 1 is supported during landing. Both supports 2 are U-shaped. The U-shaped design allows the lower horizontal part of the support 2 to contact the ground when the drone body 1 lands, making it land smoothly. Two connectors 3 are installed on the upper end of each of the two supports 2. The other ends of the four connectors 3 are fixedly connected to the drone body 1. The surface of the mounting plate 10 is machined with four mounting holes 6. The mounting holes 6 facilitate the fixing of items with ropes or other facilities. The four mounting holes 6 are evenly distributed on the surface of the mounting plate 10. The ends of the two bolts 8 are rotatably connected to the corresponding L-shaped plates 9 through bearings. When the bolts 8 rotate, they can drive the L-shaped plates 9 to move.

[0017] The working principle of this embodiment is as follows: In use, firstly, the hook 5 is inserted into the lower end of the connecting block 4. Then, the thread of the hook 5 is engaged with the thread of the connecting block 4. Next, the two bolts 8 are rotated, and the bolts 8 drive the L-shaped plate 9 to move, so that the L-shaped plate 9 abuts against the connecting block 4 and the hook 5. Then, the item to be transported is transported to a suitable position through the hook 5. When the item to be transported needs to be fixed in multiple positions, the operator unscrews the two bolts 8, so that the bolts 8 drive the L-shaped plate 9 away from the connecting block 4 and the hook 5. Then, the operator unscrews the hook 5, inserts the threaded post 11 into the lower end of the connecting block 4, and screws the threaded post 11 into the connecting block 4. Then, the bolts 8 are rotated in the opposite direction, so that the two L-shaped plates 9 abut against the lower end of the connecting block 4 and the threaded post 11, fixing the position of the mounting plate 10. Then, the rope is passed through the mounting hole 6 on the mounting plate 10 and tied to fix the item, thereby stably transporting the item through the hybrid electric drone.

[0018] 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.
