The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0022] The utility model provides a UAV wing position adjustable mechanism, such as Figure 1-4 As shown, the UAV wing position adjustable mechanism includes: a fuselage 1 for installing a mounting block 2, wherein two fixing columns 3 are fixedly installed in the mounting block 2, and transverse screws 4 are rotatably installed on the two fixing columns 3; a slide seat 5, wherein the slide seat 5 is threadedly installed on the transverse screw 4, and a slider 6 is slidably installed on the slide seat 5, and the slider 6 is used for installing the wing; a transverse motor 7, wherein the transverse motor 7 is fixedly installed in the mounting block 2, and the output shaft of the transverse motor 7 and one end of the transverse screw 4 are both provided with pulleys 8, and a belt 9 is provided on the two pulleys 8.

[0023] In this embodiment, the fuselage 1 is the main part of the UAV, which is used to carry various equipment and components. The mounting block 2 is fixed on the fuselage 1 and is used to install and support the wing adjustment mechanism. Two fixing columns 3 are installed in the mounting block 2 as the support and rotation axis of the transverse screw 4. The transverse screw 4 is connected to the slide 5 by a thread and is installed on the fixing column 3. The slide 5 can be driven to move laterally by rotation. The slide 5 is threadedly connected to the transverse screw 4 and can slide along the axial direction of the transverse screw 4, thereby driving the wing installed thereon to move laterally. The slider 6 is slidably installed on the slide 5 and is used to install the wing so that the wing can move with the movement of the slide 5. The transverse motor 7 is fixedly installed in the mounting block 2 to provide a driving force to rotate the transverse screw 4. The pulleys 8 are respectively installed on the output shafts of the transverse motor 7 And one end of the transverse screw 4 is used to transmit the rotational force of the transverse motor 7 to the transverse screw 4. The belt 9 is sleeved on the two pulleys 8 to form a transmission belt, ensuring that the rotational force of the transverse motor 7 can be smoothly transmitted to the transverse screw 4. The transverse screw 4 is driven to rotate by the transverse motor 7, so that the real-time lateral movement of the slide 5 and the slider 6 (and the wings installed thereon) can be achieved, so as to quickly adjust the wing position according to the flight status and mission requirements. The real-time adjustment of the wing position helps to optimize the flight attitude and stability of the UAV, especially in complex environments and changeable tasks, and can significantly improve the flight performance and mission execution capability of the UAV. The entire wing adjustment mechanism adopts a simple mechanical transmission method, and transmits power through pulleys 8 and belts 9. It has a simple and compact structure and high reliability, which reduces maintenance and replacement costs.

[0024] In a further preferred embodiment of the utility model, a battery box 10 is fixedly installed in the mounting block 2 , and a plurality of battery packs 11 are placed in the battery box 10 . The plurality of battery packs 11 are used to supply power to the transverse motor 7 .

[0025] In this embodiment, the battery box 10 is fixedly installed in the mounting block 2. As the power supply center of the entire wing adjustment mechanism, the design of the battery box 10 ensures the stability and ease of maintainability of the power supply. Multiple battery packs 11 are placed in the battery box 10. These battery packs 11 are all used to power the traverse motor 7. Since the real-time adjustment of the wing may require greater power support, the use of multiple battery packs 11 can ensure sufficient and stable power supply. At the same time, multiple battery packs 11 can also achieve power backup and redundancy, thereby improving the reliability of the system.

[0026] In a further preferred embodiment of the utility model, a rack 12 is slidably installed in the slide 5, and the rack 12 is connected to the slider 6. A driving gear 13 is rotatably installed in the slide 5, and the driving gear 13 is meshed with the rack 12. A driving motor 14 is fixedly installed in the slide 5, and the output shaft of the driving motor 14 is connected to the driving gear 13.

[0027] In this embodiment, the rack 12 is slidably mounted in the slide 5 and connected to the slider 6, which means that when the rack 12 slides in the slide 5, it will drive the slider 6 to move accordingly. This connection between the rack 12 and the slider 6 makes the movement of the slider 6 more accurate and stable. The drive gear 13 is rotatably mounted in the slide 5 and meshes with the rack 12. When the drive gear 13 rotates, it will drive the rack 12 to slide through the meshing action between the teeth. This design provides an effective power transmission method, so that the movement of the slider 6 can be achieved through the rotation of the drive gear 13. When the drive motor 14 is started, it will drive the drive gear 13 to rotate through the output shaft, and then drive the rack 12 and the slider 6 to slide. Through the meshing action of the drive motor 14 and the drive gear 13 with the rack 12, the movement of the slider 6 can be accurately controlled, and the wing can be precisely adjusted up and down, so that the position adjustment of the wing is more accurate, meeting the needs of complex flight missions.

[0028] In a further preferred embodiment of the utility model, a mounting frame 15 is fixedly installed in the mounting block 2 , a fan 16 and a cooling fin 17 are fixedly installed in the mounting frame 15 , and the cooling fin 17 is located at the air outlet side of the fan 16 .

[0029] In this embodiment, the mounting frame 15 is fixedly installed in the mounting block 2 as an integrated frame for fixing and supporting the fan 16 and cooling fins 17 mentioned later. The fan 16 is fixedly installed in the mounting frame 15, and its main function is to provide cooling airflow for the system. When the fan 16 is running, it will inhale the surrounding air and blow it to the cooling fins 17 to form an effective heat dissipation effect. The cooling fins 17 are located on the air outlet side of the fan 16, that is, the wind blown by the fan 16 will blow directly to the cooling fins 17. Through the coordinated use of the fan 16 and the cooling fins 17, the heat dissipation effect of the UAV wing adjustment mechanism can be significantly improved, which helps to reduce the system temperature and prevent performance degradation or equipment damage caused by overheating.

[0030] In a further preferred embodiment of the utility model, the top of the mounting block 2 is fixedly connected to a ventilation pipe 18 , one end of the ventilation pipe 18 is provided with an air guide scoop, and the ventilation pipe 18 and the air guide scoop are both arranged corresponding to the air inlet end of the fan 16 .

[0031] In this embodiment, the ventilation duct 18 is fixedly connected to the top of the mounting block 2, and it serves to guide external air to the air inlet end of the fan 16, ensuring that the fan 16 can continuously obtain fresh air for heat dissipation, thereby improving the heat dissipation efficiency. The wind guide scoop is arranged at one end of the ventilation duct 18, and its function is to more effectively collect and guide external air into the ventilation duct 18. By using it in conjunction with the ventilation duct 18, the wind guide scoop can ensure that more air is sucked in and guided to the air inlet end of the fan 16, thereby further enhancing the heat dissipation effect.

[0032] In a further preferred embodiment of the utility model, two upright posts are fixedly installed in the installation block 2 , and at least one deviation-correcting rod 19 is fixedly installed on the two upright posts. The deviation-correcting rod 19 slidably passes through the slide seat 5 .

[0033] In this embodiment, two columns are fixedly installed in the mounting block 2. The two columns serve as supporting structures for fixing and installing the correcting rod 19. The correcting rod 19 is fixedly installed on the two columns, and it slides through the slide 5, so that the correcting rod 19 can play a guiding and correcting role when the slide 5 moves. When the slide 5 moves driven by the transverse screw 4, the correcting rod 19 can ensure that the slide 5 moves smoothly in a straight line direction and prevent it from deviating from the predetermined trajectory, which is crucial for maintaining the stable position and posture of the wing.

[0034] In a further preferred embodiment of the present invention, a guide rod 20 is fixedly mounted on the inner walls of both sides of the slide seat 5 , a guide groove 21 is formed on the rack 12 , and the guide rod 20 slides through the guide groove 21 .

[0035] In this embodiment, the guide rod 20 is fixedly mounted on the inner walls of both sides of the slide 5 as a stable support and guide structure. Its main function is to ensure that the rack 12 can maintain linear motion when sliding in the slide 5, and prevent the rack 12 from deflecting or twisting during the sliding process. The guide groove 21 is provided on the rack 12, corresponding to the guide rod 20. When the rack 12 slides in the slide 5, the guide rod 20 will slide through the guide groove 21, ensuring the stability and reliability of the rack 12 during the sliding process, and also limiting the motion trajectory of the rack 12 so that it can only move in a linear direction.

[0036] In summary, compared with the relevant technology, the present device has achieved multiple optimizations and enhancements as a whole, improved the stability and reliability of UAV wing adjustment, enhanced heat dissipation effect, and improved the precision and accuracy of wing adjustment. The lateral position change of the wing will improve the distribution of the UAV lift, and the vertical position change of the wing may affect its angle of attack, thereby changing the lift-to-drag ratio. By adjusting the vertical position of the wing, the lift-to-drag ratio can be optimized, the flight efficiency of the UAV can be improved, and the heat dissipation performance can be effectively improved, ensuring that the adjustment mechanism can still maintain stable performance under long-term and high-load operation, enhancing the heat dissipation effect, improving air circulation, and ensuring stability and linearity during movement, thereby improving the precision and accuracy of wing adjustment, which not only improves the overall performance of the UAV, but also reduces the risk of failure and maintenance costs, making the UAV more reliable and efficient when performing high-precision tasks in complex environments.
