Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically to an UAV wing extension and adjustment structure. Background Technology

[0002] The rotor of a drone is a key component that generates lift or thrust by rotating at high speed on a drone. It is usually made of lightweight, high-strength materials. In a multi-rotor drone, multiple rotors are symmetrically distributed and their rotation speed is controlled independently. They can provide vertical lift by rotating rapidly to enable the drone to take off, hover, or land. They can also achieve attitude control by adjusting the speed difference between different rotors, and complete flight maneuvers such as forward, backward, and turning. It is an important structure to ensure the flexible and stable flight of a drone.

[0003] For example, Chinese Patent Application No. 201620200131.9 discloses an unmanned aerial vehicle (UAV) system, including a UAV, an imaging device fixedly connected to the UAV, and a mobile control terminal wirelessly communicating with the UAV. The mobile control terminal sends zoom commands to the UAV. The UAV distributes the zoom commands to the imaging device. The imaging device receives the zoom commands and performs corresponding zoom actions according to the zoom commands. The imaging device of this UAV can wirelessly remotely control zoom, achieving precise monitoring of the locked target.

[0004] In actual use, the excessively long wingspan of drones becomes a major problem. When drones are not in use and need to be stored, their large size takes up too much space, causing great inconvenience to the storage process.

[0005] Therefore, it is necessary to redesign and modify the wing extension and adjustment structure of the drone to effectively prevent it from becoming inconvenient to store. Utility Model Content

[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide a wing extension and adjustment structure for unmanned aerial vehicles (UAVs), which has the advantages of being easy to use and solves the problem of inconvenient storage.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a UAV wing extension adjustment structure, including a body, with a flip extension mechanism provided at each of the four corners of the body. The flip extension mechanism includes a fixing block fixedly connected to each of the four corners of the body, a support plate fixedly connected to the outer side of the fixing block, a round rod movably connected to the inner wall of the support plate via a bearing, a connecting block fixedly connected to the outer side of the round rod, a screw fixedly connected to the outer side of the connecting block, an extension cylinder slidably sleeved on the surface of the screw, a rotor mounted on the outer side of the extension cylinder, and a fixing mechanism provided on the outer surface of the screw.

[0008] In a preferred embodiment of this utility model, the fixing mechanism includes a limiting plate fixedly connected to the outside of the fixing block. A bolt is provided on the upper side of the limiting plate, and the bolt passes through the bottom of the connecting block from top to bottom and extends into the interior of the limiting plate. The surface of the bolt is threadedly connected to the inner wall of the connecting block and the limiting plate. Arc-shaped blocks are slidably connected to the upper and lower sides of the screw. The outer side of the arc-shaped blocks is fixedly connected to the inner wall of the extension cylinder. A fixing cylinder is threadedly connected to the outer surface of the screw and the arc-shaped blocks. A slider is fixedly connected to the surface of the screw. A groove is formed on the surface of the extension cylinder. The slider slides back and forth inside the groove to prevent the extension cylinder from rotating.

[0009] As a preferred embodiment of this invention, the screw is threadedly connected to a limiting sleeve, which is used to abut against the fixing sleeve to prevent it from loosening.

[0010] As a preferred embodiment of this invention, the surfaces of the limiting cylinder and the fixing cylinder are fixedly covered with anti-slip sleeves, which are used to prevent the hand from slipping during rotation.

[0011] As a preferred embodiment of this invention, a support rod is fixedly connected to the bottom of the fixing block, and the support rod is used to support the overall structure.

[0012] As a preferred embodiment of this invention, the surface of the support plate is provided with rounded corners, which are used to prevent sharp edges from scratching the operator.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. When this utility model is used, the flipping extension mechanism and the fixing mechanism can reduce the space occupied by the drone during storage, avoiding the inconvenience of storage caused by the large space occupied by the drone, and making it easy to use.

[0015] 2. This utility model achieves a stable connection between the extension cylinder and the screw after extension by setting a fixing mechanism. This ensures that the rotor will not be affected by shaking or rotation during operation, thus improving the safety and reliability of the UAV flight.

[0016] 3. This utility model effectively prevents the fixing cylinder from loosening by setting a limiting cylinder. During the flight of the drone, it will be subjected to various external forces. The presence of the limiting cylinder ensures the stability of the entire fixing structure, avoids rotor position deviation due to loosening of the fixing cylinder, and further ensures smooth flight.

[0017] 4. This utility model, by incorporating anti-slip sleeves, allows operators to apply force more effectively and reduces the risk of slippage when rotating the components for fixing or loosening. This not only improves operational accuracy and efficiency but also reduces the possibility of damage to parts due to slippage, thus enhancing the user experience.

[0018] 5. By setting up support rods, this utility model provides support for the entire flipping and extension mechanism and the machine body, thereby enhancing the stability of the structure.

[0019] 6. By setting rounded corners, this utility model avoids sharp edges from scratching operators, reflecting the human-centered design of the product and reducing safety risks during use. Attached Figure Description

[0025] 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 protection scope of the present utility model.

[0026] like Figures 1 to 4 As shown, the UAV wing extension adjustment structure provided by this utility model includes a body 1, with a flip extension mechanism set at each of the four corners of the body 1. The flip extension mechanism includes a fixing block 2 fixedly connected to the four corners of the body 1, a support plate 3 fixedly connected to the outer side of the fixing block 2, a round rod 4 movably connected to the inner wall of the support plate 3 through a bearing, a connecting block 5 fixedly connected to the outer side of the round rod 4, a screw 6 fixedly connected to the outer side of the connecting block 5, an extension cylinder 7 slidably sleeved on the surface of the screw 6, a rotor 8 installed on the outer side of the extension cylinder 7, and a fixing mechanism set on the outer surface of the screw 6.

[0027] refer to Figure 4The fixing mechanism includes a limiting plate 9 fixedly connected to the outside of the fixing block 2. A bolt 10 is provided on the upper side of the limiting plate 9. The bolt 10 passes through the bottom of the connecting block 5 from top to bottom and extends into the interior of the limiting plate 9. The surface of the bolt 10 is threadedly connected to the inner wall of the connecting block 5 and the limiting plate 9. Arc-shaped blocks 11 are slidably connected to the upper and lower sides of the screw 6. The outer side of the arc-shaped blocks 11 is fixedly connected to the inner wall of the extension cylinder 7. A fixing cylinder 12 is threadedly connected to the outer surface of the screw 6 and the arc-shaped blocks 11. A slider 13 is fixedly connected to the surface of the screw 6. A groove 14 is opened on the surface of the extension cylinder 7. The slider 13 slides back and forth inside the groove 14 to prevent the extension cylinder 7 from rotating.

[0028] As a technical optimization of this utility model, a fixing mechanism is set up to achieve a stable connection between the extension cylinder 7 and the screw 6 after extension. This ensures that the rotor 8 will not be affected by shaking or rotation during operation, thus improving the safety and reliability of the UAV flight.

[0029] refer to Figure 4 The screw 6 has a threaded connection to a limiting sleeve 15, which is used to press against the fixing sleeve 12 to prevent it from loosening.

[0030] As a technical optimization of this utility model, the limiting cylinder 15 effectively prevents the fixing cylinder 12 from becoming loose. During the flight of the UAV, it will be subjected to various external forces. The presence of the limiting cylinder 15 ensures the stability of the entire fixing structure, avoids the rotor 8 from shifting position due to the loosening of the fixing cylinder 12, and further ensures the smoothness of flight.

[0031] refer to Figure 4 The surfaces of the limiting cylinder 15 and the fixing cylinder 12 are fixedly covered with anti-slip sleeves 16, which are used to prevent the hand from slipping during rotation.

[0032] As a technical optimization of this utility model, by setting the anti-slip sleeve 16, operators can better exert force and are less likely to slip when rotating them to fix or loosen them. This not only improves the accuracy and efficiency of operation, but also reduces the possibility of damage to parts due to operational errors caused by slipping, thus enhancing the user experience.

[0033] refer to Figure 2 The bottom of the fixing block 2 is fixedly connected to a support rod 17, which is used to support the overall structure.

[0034] As a technical optimization of this utility model, by setting a support rod 17, support is provided for the entire flipping extension mechanism and the body 1, thereby enhancing the stability of the structure.

[0035] refer to Figure 2The surface of the support plate 3 is provided with rounded corners 18, which are used to prevent sharp edges from scratching the operator.

[0036] As a technical optimization of this utility model, by setting a rounded corner of 18, the sharp edges and corners are prevented from scratching the operator, which reflects the humanization of product design and reduces the safety risks during use.

[0037] The working principle and usage process of this utility model are as follows: In use, the fixing blocks 2 at the four corners of the body 1 are connected to the support plate 3. The round rod 4 is connected to the support plate 3 through bearings and can rotate flexibly. The round rod 4 drives the connecting block 5 and the screw 6 to rotate, realizing the upward flipping action of the extension tube 7 and the rotor 8. When the extension tube 7 extends outward to the appropriate position, it is fixed by the fixing mechanism. The bolt 10 passes through the connecting block 5 and the limiting plate 9 and is threadedly connected. The arc-shaped block 11 slides with the screw 6 and is then locked by the fixing tube 12 and the limiting tube 15 (the fixing tube 12 is connected to the screw 6 and the surface of the arc-shaped block 11 through the continuous thread, thereby fixing the relative position of the arc-shaped block 11 and the screw 6). The slider 13 slides in the slide groove 14 to prevent the extension tube 7 from rotating, thereby ensuring the stable operation of the rotor 8. When storing, the above steps are reversed to reduce the overall space occupied by the drone. This avoids the inconvenience of storing a large space occupied by the drone and makes it easy to use.

[0038] In summary, when this utility model is used, the flipping extension mechanism and the fixing mechanism can reduce the space occupied by the drone during storage, avoiding the inconvenience caused by the large space occupied by the drone, and making it easy to use.
