Technical Field

[0001] This utility model relates to the field of drones, specifically a foldable drone arm quick-release device. Background Technology

[0002] A drone arm quick-release device is a structural component used for the rapid assembly and folding of drone arms. Its purpose is to improve the portability and deployment efficiency of drones, while facilitating transportation and storage. Through the quick-release design, people can easily separate or lock the arms without tools, while the folding function further reduces the size of the drone body, adapting to the needs of confined spaces or field operations, and taking into account both flexibility of use and ease of operation.

[0003] In existing technology, a drone is a flying device controlled by remote control or autonomous programs, mainly used for tasks such as aerial photography, reconnaissance, transportation, and agricultural spraying. It is characterized by its flexibility, efficiency, and ability to replace manual labor. When launching drones, people usually take them to a relatively open area. However, drones are relatively large and take up a lot of space during transportation. Therefore, people usually disassemble the drone's arms to make the transportation process more convenient. The traditional method of disassembly and assembly often uses bolts to fix the drone's arms and fuselage together. Although this method can effectively connect the drone's arms and fuselage, it often takes a long time to disassemble the bolts and requires the use of additional tools, such as screwdrivers, making the disassembly and assembly process of the drone's arms quite cumbersome. Utility Model Content

[0004] To address the shortcomings of existing technologies, traditional disassembly and installation methods often involve using bolts to fix the drone's arms and fuselage together. While this method effectively connects the drone's arms and fuselage, removing the bolts often takes a considerable amount of time and requires additional tools such as screwdrivers, making the disassembly and installation of the drone's arms quite cumbersome. This invention proposes a foldable quick-release device for drone arms.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a foldable drone arm quick-release device, including a drone body, the surface of the drone body is provided with a connecting side plate, multiple connecting side plates are provided, one side of each of the multiple connecting side plates is provided with a quick-release mechanism, two quick-release mechanisms are provided, one of which is fixedly connected to a folding arm.

[0006] The quick-release mechanism includes a housing, one side of which is fixedly connected to one side of a connecting side plate. A connecting buckle is fixedly connected to one side of the housing. A hook spring is movably connected to the inner cavity of the connecting buckle. A lever is movably connected to one end of the hook spring. A semi-circular block is fixedly connected to one side of the lever. A connecting block is fixedly connected to one side of the housing. A limit plate is fixedly connected to one side of the connecting block. One side of the limit plate is fixedly connected to the inner cavity of the housing. A mounting plate is fixedly connected to one side of the connecting block. One side of the semi-circular block is rotatably connected to the surface of the mounting plate.

[0007] Preferably, one of the housings is fixedly connected to one side of a mounting block, the inner cavity of the mounting block is slidably connected to a sliding block, one side of the sliding block is fixedly connected to a dustproof plate, one side of the mounting block is provided with a limit hole, a plurality of limit holes are provided, one of the limit holes is movably engaged with a limit rod in the inner cavity, and one end of the limit rod is movably engaged with the inner cavity of the sliding block.

[0008] Preferably, the inner cavity of the mounting block is provided with a limiting groove, one side of the sliding block is fixedly connected to a limiting block, and the surface of the limiting block is slidably connected to the inner cavity of the limiting groove.

[0009] Preferably, a fixing block is fixedly connected to one side of one of the housings, and a fixing rod is movably engaged in the inner cavity of the fixing block; a fixing groove is opened on one side of the other connecting block, and one end of the fixing rod is movably engaged in the inner cavity of the fixing groove.

[0010] Preferably, one of the housings and the connecting block has a connecting groove in its inner cavity, and the other connecting block has a connecting rod fixedly connected to one side, with the surface of the connecting rod slidably connected to the inner cavity of the connecting groove.

[0012] Preferably, a reinforcing block is fixedly connected to the surface of the connecting side plate, and one side of the reinforcing block is fixedly connected to one side of the UAV body.

[0013] The advantages of this utility model are:

[0014] This invention involves inserting two housings into each other. When one housing is inserted into the other, a semicircular block pushes the other semicircular block, causing both semicircular blocks to rotate. A connecting block limits the movement of the two semicircular blocks, thus locking the two quick-release mechanisms. Through the mutual locking between the two quick-release mechanisms, the drone arm can be quickly installed and disassembled, allowing people to easily assemble and disassemble the drone arm without the need for other tools. This solves the problem that traditional disassembly and installation methods often use bolts to fix the drone arm and body together. While this method can effectively connect the drone arm and body, it often takes a long time to remove the bolts and requires additional tools such as screwdrivers, making the disassembly and installation of the drone arm cumbersome.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0027] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0028] This application discloses a foldable quick-release device for the arm of a drone. (Refer to...) Figure 1 and Figure 2 A foldable drone arm quick-release device includes a drone body 1. The surface of the drone body 1 is provided with a connecting side plate 4. Multiple connecting side plates 4 are provided. Each side of the multiple connecting side plates 4 is provided with a quick-release mechanism 3. There are two quick-release mechanisms 3. One side of one quick-release mechanism 3 is fixedly connected to a foldable arm 2.

[0029] The quick-release mechanism 3 includes a housing 301. One side of the housing 301 is fixedly connected to one side of the connecting side plate 4. A connecting buckle 302 is fixedly connected to one side of the housing 301. A hook spring 303 is movably connected to the inner cavity of the connecting buckle 302. A lever 304 is movably connected to one end of the hook spring 303. A semi-circular block 305 is fixedly connected to one side of the lever 304. A connecting block 306 is fixedly connected to one side of the housing 301. A limiting plate 307 is fixedly connected to one side of the connecting block 306. One side of the limiting plate 307 is fixedly connected to the inner cavity of the housing 301. A mounting plate 308 is fixedly connected to one side of the connecting block 306. One side of the semi-circular block 305 is rotatably connected to the surface of the mounting plate 308.

[0030] The drone body 1 is a flight device controlled by remote control or autonomous program, mainly used for aerial photography, reconnaissance, transportation, agricultural spraying, and other tasks. It features flexibility, efficiency, and the ability to replace manual labor. The folding arm 2 reduces the overall size of the drone, making it easier to carry and transport. At the same time, it can be quickly unfolded while ensuring structural strength and stability during flight. The drone body 1 and the folding arm 2 are existing technologies in this field, so they will not be described in detail here. There are two quick-release mechanisms 3, which are identical in structure and can be spliced ​​together. Since two quick-release mechanisms 3 are provided on one side of each of the multiple connecting side plates 4,... Therefore, there are two housings 301. One housing 301 is connected to one side of the connecting side plate 4, while the other housing 301 is connected to one side of the folding arm 2. The connecting buckle 302 provides a mounting function for the hook spring 303 through its connection with the housing 301. At the same time, one end of the hook spring 303 is connected to the lever 304. When the lever 304 moves, it will stretch the hook spring 303 during the movement. When the lever 304 stops moving, the hook spring 303 will drive the lever 304 to elastically reset. The lever 304 is connected to the semi-circular block 305. Meanwhile, the housing... 301 can provide installation and connection for the limiting plate 307 and the mounting plate 308 through the connecting block 306. Both the semicircular block 305 and the connecting block 306 are connected to the mounting plate 308, so that when the two quick-release mechanisms 3 are spliced ​​together, one connecting block 306 will drive one of the mounting plates 308 and the semicircular block 305 to insert into the interior of the other housing 301. Furthermore, the connecting block 306 will push one of the semicircular blocks 305 with the force of a person, causing the other semicircular block 305 to drive another lever 304 to rotate along the surface of the other mounting plate 308. Meanwhile, the semicircular block 305... During insertion, the connecting block 306 will fit against the surfaces of the two semicircular blocks 305 and limit their movement. When the two semicircular blocks 305 are aligned, the connecting block 306 will release the limiting effect on the two semicircular blocks 305. At this time, the two hook springs 303 will pull back the two levers 304 due to their own force, and drive the two semicircular blocks 305 to rotate forty-five degrees through the two levers 304. After the two semicircular blocks 305 have rotated forty-five degrees, the connection point of the two semicircular blocks 305 will fit against the connecting block 306 again and be limited by the connecting block 306, thereby achieving mutual locking of the two quick-release mechanisms 3.

[0031] Reference Figure 2 and Figure 3One of the housings 301 has a mounting block 6 fixedly connected to one side. A sliding block 7 is slidably connected to the inner cavity of the mounting block 6. A dustproof plate 8 is fixedly connected to one side of the sliding block 7. A limit hole 9 is provided on one side of the mounting block 6. Multiple limit holes 9 are provided. A limit rod 10 is movably engaged in the inner cavity of one of the limit holes 9. One end of the limit rod 10 is movably engaged in the inner cavity of the sliding block 7. A connecting block 306 is connected to the mounting block 6. The sliding block 7 provides the installation function for the dustproof plate 8 through its connection with the mounting block 6. When the other quick-release mechanism 3 is disassembled, the dustproof plate 8 can be pulled, and the sliding block 7 can be slid along the inner cavity of the mounting block 6 through the dustproof plate 8. At the same time, the sliding block 7 is aligned with one of the limit holes 9, and the limit rod 10 is inserted into the interior of the mounting block 6 and the sliding block 7, thereby completing the limitation of the sliding block 7. The dustproof plate 8 can shield the quick-release mechanism 3, making it difficult for external dust and foreign objects to enter the interior of the quick-release mechanism 3, thus playing a protective role for the quick-release mechanism 3.

[0032] Reference Figure 2 and Figure 8 The inner cavity of the mounting block 6 is provided with a limiting groove 11. A limiting block 12 is fixedly connected to one side of the sliding block 7. The surface of the limiting block 12 is slidably connected to the inner cavity of the limiting groove 11. The sliding block 7 can provide installation and connection for the limiting block 12. By providing a limiting groove 11 in the inner cavity of the mounting block 6, the limiting block 12 can slide inside the limiting groove 11. The limiting block 12 plays a certain limiting role for the sliding block 7, so that the sliding block 7 can slide more smoothly and is less likely to deviate.

[0033] Reference Figure 2 and Figure 4 One of the housings 301 has a fixed block 13 fixedly connected to one side, and a fixing rod 15 is movably engaged in the inner cavity of the fixing block 13. Another connecting block 306 has a fixing groove 14 on one side, and one end of the fixing rod 15 is movably engaged in the inner cavity of the fixing groove 14. One of the connecting blocks 306 is connected to the fixing block 13, and the fixing block 13 can provide an installation function for the fixing rod 15. After the two quick-release mechanisms 3 are spliced ​​together, the fixing block 13 will slide along the surface of the other quick-release mechanism 3 to the top of the fixing groove 14. People can insert the fixing rod 15 into the inside of the fixing groove 14, thereby achieving the reinforcement of the two quick-release mechanisms 3 and making it difficult for the two quick-release mechanisms 3 to detach.

[0034] Reference Figure 1 and Figure 5One of the housings 301 and the inner cavity of the connecting block 306 are provided with connecting grooves 16. A connecting rod 17 is fixedly connected to one side of the other connecting block 306. The surface of the connecting rod 17 is slidably connected to the inner cavity of the connecting groove 16. The other connecting block 306 is connected to the connecting rod 17. By providing a connecting rod 17 on one side of the connecting block 306 and the housing 301, the connecting rod 17 can slide inside the connecting groove 16. The connecting groove 16 can make the connection between the two quick-release mechanisms 3 more stable and less prone to shaking and displacement.

[0035] Reference Figure 1 and Figure 6 Both the connecting buckle 302 and the lever 304 have rubber rings 18 movably bonded to their inner cavities. The surface of the rubber ring 18 is movably connected to the surface of the hook spring 303. Both the connecting buckle 302 and the lever 304 are connected to the rubber ring 18. The rubber ring 18 can prevent the hook spring 303 from breaking due to wear when it is used, thereby extending the service life of the hook spring 303 to a certain extent.

[0036] Reference Figure 1 and Figure 2 A reinforcing block 5 is fixedly connected to the surface of the connecting side plate 4. One side of the reinforcing block 5 is fixedly connected to one side of the drone body 1. The connecting side plate 4 is connected to the reinforcing block 5, and the reinforcing block 5 is connected to the drone body 1. The reinforcing block 5 reinforces the connecting side plate 4 through its connection with the drone body 1, so that the connecting side plate 4 can better connect one of the shells 301.

[0037] Working Principle: Before use, the drone body 1 is a flight device controlled by remote control or autonomous program. The folding arm 2 reduces the overall size of the drone, making it easy to carry and transport. Simultaneously, when quickly unfolded, it maintains structural strength and stability during flight. When the folding arm 2 needs to be quickly installed, the two quick-release mechanisms 3 can be aligned, and the quick-release mechanism 3 connected to the folding arm 2 can be inserted into the quick-release mechanism 3 connected to the drone body 1. When the other quick-release mechanism 3 is inserted into the first quick-release mechanism 3, one connecting block 306 will drive one mounting plate 308 and a semi-circular block 305 to be inserted into the other housing 301. Furthermore, the connecting block 306 will push the semi-circular block 305 further into the housing 301 with the user's thrust. The pushing motion causes another semicircular block 305 to rotate along the surface of another mounting plate 308, driving another lever 304. During the insertion of the other semicircular block 305, the connecting block 306 will fit against the surfaces of the two semicircular blocks 305 and limit their movement. When the two semicircular blocks 305 are aligned, the connecting block 306 will release its limiting effect on the two semicircular blocks 305. At this time, the two hook springs 303 will pull back the two levers 304 due to their own force, and drive the two semicircular blocks 305 to rotate 45 degrees through the two levers 304. After the two semicircular blocks 305 have rotated 45 degrees, the connection point of the two semicircular blocks 305 will fit against the connecting block 306 again and be limited by the connecting block 306, thereby achieving mutual locking of the two quick-release mechanisms 3.

[0038] Furthermore, when it is necessary to disassemble the folding arm 2, another lever 304 can be pulled, and another semicircular block 305 can be pulled by the other lever 304, causing the other semicircular block 305 to rotate. When the semicircular block 305 rotates, it will drive the other semicircular block 305 to rotate synchronously. After the semicircular block 305 rotates to a certain angle, the connecting block 306 will release the limit on the two semicircular blocks 305. At this time, another quick-release mechanism 3 can be pulled out, thereby completing the quick disassembly of the folding arm 2.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
