However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0024] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1:

[0026] Reference Figure 1-7A foldable photovoltaic wing assembly for a drone includes a drone body 1, wings 2 on both sides of the drone body 1, mounting grooves 3 on the top surface of each wing 2, sliding grooves 13 at both ends of the bottom surface of the mounting grooves 3, guide grooves 14 on both sides of the sliding grooves 13, a mounting frame 6 inside the drone body 1, two brushless motors 7 on one side of the mounting frame 6, a drum 5 on the side of each brushless motor 7 near the mounting frame 6, and a rotating rod 15 on the side of each drum 5 near the mounting frame 6. The mounting grooves 3 on the surfaces of the two wings 2 are located away from the drone body 1. Each side has two mounting slots 9, and each mounting slot 3 has a flexible solar panel 4 inside. Each flexible solar panel 4 has a locking block 8 at the end furthest from the drone body 1. Each locking block 8 has two sliders 11 on its bottom surface. Each slider 11 has guide blocks 12 on both sides. Each locking block 8 has two fixing brackets 10 on the side furthest from the drone body 1. Both wings 2 are integrally formed with the drone body 1, and the mounting slots 3 on the top surfaces of the two wings 2 are positioned one-to-one. Each locking block 8 is integrally formed with the two fixing brackets 10 on its surface, and each locking block 8 is integrally formed with the two fixing brackets 10 on its bottom surface. Two sliders 11 are integrally formed, and all four sliders 11 are integrally formed with two guide blocks 12 on their surfaces. The positions of the two sliders 11 correspond one-to-one with the positions of the slide grooves 13, and the positions of the guide grooves 14 on the surface of the slide grooves 13 correspond one-to-one with the positions of the guide blocks 12 on the surface of the sliders 11. The positions of the four fixing grooves 9 correspond one-to-one with the positions of the two fixing brackets 10 on the surface of the two locking blocks 8. The two locking blocks 8 are installed inside the mounting grooves 3, and the two sliders 11 on the bottom surface of the locking blocks 8 are installed in the slide grooves 13. The two guide blocks 12 on the surface of the four sliders 11 are installed in the slide grooves. In the guide groove 14 on the surface of 13, the mounting brackets 6 are all installed inside the drone body 1 and are welded to the inner wall of the drone body 1. The two brushless motors 7 are all installed inside the drone body 1 and are bolted to the drone body 1. The two rollers 5 are all shaft-connected to the brushless motors 7 and are integrally formed with the rotating rods 15 on the surface. One end of the two rotating rods 15 passes through the mounting brackets 6. The two flexible solar panels 4 are all installed inside the mounting groove 3. One end of the two flexible solar panels 4 is engaged with the locking block 8 and the other end of the flexible solar panels 4 is bonded to the rollers 5.

[0027] The drone body 1 serves as the carrier of the entire system, accommodating and fixing other components, providing a mounting base, and connecting with other components through internal circuitry to achieve functions such as control and power transmission. The wing 2 is integrally formed with the drone body 1, providing lift, and its top mounting slot 3 is used to install the flexible solar panel 4. The mounting slot 3 provides installation space for the flexible solar panel 4, locking block 8, slider 11, and guide block 12, defining the installation position and range of motion of the components. The flexible solar panel 4 converts solar energy into electrical energy through the photoelectric effect to power the drone. One end is engaged with the locking block 8, and the other end is bonded to the drum 5, allowing it to extend or retract under the action of the drum 5. The drum 5 is shaft-connected to the brushless motor 7, rotating under the drive of the brushless motor 7, and using the end bonded to the flexible solar panel 4 to achieve the rolling and unfolding action of the flexible solar panel 4. The mounting bracket 6 is installed inside the drone body 1 and welded to the inner wall to fix the rotating rod 15, ensuring stable rotation of the drum 5. The brushless motor 7, powered by the control system, converts electrical energy into mechanical energy, driving the drum 5 to rotate, thereby controlling the unfolding and retraction of the flexible solar panel 4. The locking block 8 engages with one end of the flexible solar panel 4. Its bottom slider 11 and guide block 12 cooperate with the sliding groove 13 and guide groove 14 in the mounting slot 3 of the wing 2 to ensure the stability of the flexible solar panel 4 during movement. Simultaneously, the fixing bracket 10 cooperates with the fixing groove 9 on the wing 2 to fix the flexible solar panel 4 in the unfolded state. The fixing groove 9 cooperates with the fixing bracket 10 on the locking block 8, and through fixing bolts and other connecting parts, fixes the flexible solar panel 4 to the wing 2 when unfolded. The fixing bracket 10 is integrally formed with the locking block 8 and cooperates with the fixing groove 9 for fixing the flexible solar panel 4 when unfolded. The slider 11 is integrally formed with the locking block 8 and moves within the sliding groove 13, limiting the displacement of the locking block 8 and the flexible solar panel 4 perpendicular to the direction of movement, ensuring that the flexible solar panel 4 moves along the set direction. The guide block 12 is integrally formed with the slider 11 and moves within the guide groove 14, further guiding and constraining the movement direction of the slider 11 to prevent it from deviating during movement and ensuring the smooth movement of the flexible solar panel 4. The slide groove 13 cooperates with the slider 11 to provide a moving track for the slider 11 and limits the movement path of the locking block 8 and the flexible solar panel 4. The guide groove 14 cooperates with the guide block 12 to assist in guiding the movement direction of the slider 11 and enhance the stability of the flexible solar panel 4 during movement. The rotating rod 15 is integrally formed with the drum 5, with one end passing through the mounting frame 6, and is used to transmit the power of the brushless motor 7 to ensure that the drum 5 can rotate stably. Specific Implementation Example 2:

[0029] Reference Figure 1-7A foldable photovoltaic wing component for drones is further based on the basic structure in Specific Embodiment 1. In use, the fixing bracket 10 on the clip 8 is connected to the fixing groove 9 on the wing 2 by fixing bolts, so that the flexible solar panel 4 is unfolded and fixed in the mounting groove 3 on the top surface of the wing 2. At this time, the flexible solar panel 4 is exposed to the outside world to absorb solar energy and convert it into electrical energy to power the drone.

[0030] When the photovoltaic wing assembly needs to be retracted, first remove the fixing bolts on the mounting bracket 10 to release the flexible solar panel 4. Then, the UAV control system issues a command to start the brushless motor 7, which drives the drum 5 to rotate. Since one end of the flexible solar panel 4 is bonded to the drum 5, the rotation of the drum 5 will move the flexible solar panel 4. During the movement, the slider 11 on the bottom of the locking block 8 slides in the slide groove 13, and the guide blocks 12 on both sides of the slider 11 slide in the guide groove 14, which plays a guiding and stabilizing role, ensuring that the flexible solar panel 4 moves smoothly and is finally rolled up by the drum 5 and stored in the mounting groove 3. When it is needed to be used again, the brushless motor 7 rotates in the opposite direction, the drum 5 unfolds the flexible solar panel 4, the slider 11 and the guide blocks 12 cooperate to ensure its smooth unfolding, and then the mounting bracket 10 is connected to the mounting groove 9 by fixing bolts to fix the flexible solar panel 4 and put it into working state.

[0031] In summary:

[0032] 1. When not in use, remove the fixing bolts on the fixing bracket 10. After removal, turn on the brushless motor 7 through the drone's control system to make the brushless motor 7 drive the drum 5 to rotate. The rotating drum 5 drives the flexible solar panel 4. When moving, the slider 11 on the bottom of the locking block 8 will move in the slide groove 13, and the guide blocks 12 on both sides of the slider 11 will also move in the guide groove 14. The slider 11 and the guide blocks 12 ensure that the flexible solar panel 4 can move smoothly. Finally, the flexible solar panel 4 is rolled up and stored by the drum 5, which solves the problem of photovoltaic modules being difficult to fold and store.
