[0023] Unless otherwise defined, all technical terms used herein have the same meaning as commonly understood by those skilled in the art. The technical terms used herein are for the purpose of describing particular embodiments only and are not intended to limit the scope of protection of this invention.

[0024] To address the problems of existing photovoltaic power generation devices being large in size, inconvenient to transport, and difficult to store, such as Figure 1 and Figure 2As shown, this application provides a foldable solar tracking power generation device, which includes a foldable bracket 1, a solar tracking drive component 2, and a photovoltaic power generation component 3.

[0025] The foldable support 1, when unfolded, can be stably supported on the external foundation, providing necessary structural support and stability for the entire power generation device and ensuring its reliable mechanical load-bearing capacity during operation. The solar tracking drive component 2 is installed on the foldable support 1 and forms a drive connection with the photovoltaic power generation component 3. Its function is to drive the photovoltaic power generation component 3 to adjust its angle according to the sun's movement trajectory, thereby tracking sunlight and improving photovoltaic power generation efficiency.

[0026] The photovoltaic power generation module 3 includes a foldable photovoltaic support 31 and a photovoltaic panel 32. The foldable photovoltaic support 31 has two working modes: an unfolded state and a folded state. In the unfolded state, the foldable photovoltaic support 31 is installed on the light-tracking drive module 2 to support the photovoltaic panel 32 and position it in a suitable position for receiving sunlight. In the folded state, the foldable photovoltaic support 31 and the photovoltaic panel 32 are separated, so that they can be stored or transported separately when not in use, while further reducing the space required for the device.

[0027] The foldable solar tracking power generation device provided in this application achieves structural foldability and modular design while ensuring power generation and tracking performance, which helps to improve its ease of operation during transportation, installation and daily maintenance.

[0028] like Figure 1 and Figure 6 As shown in a specific embodiment of this application, the foldable photovoltaic support 31 includes a first photovoltaic support 311, a second photovoltaic support 312, and a hinge 313. The first photovoltaic support 311 is connected to one movable end of the hinge 313, and the second photovoltaic support 312 is connected to the other movable end of the hinge 313. Through the hinge action of the hinge 313, the first photovoltaic support 311 and the second photovoltaic support 312 can switch between an unfolded state and a folded state. When in the unfolded state, the first photovoltaic support 311 and the second photovoltaic support 312 unfold to a predetermined angle via the hinge 313 and remain relatively fixed, thereby providing a stable support foundation for the photovoltaic panel 32 and ensuring that it can reliably receive sunlight during operation. When in the folded state, the first photovoltaic support 311 and the second photovoltaic support 312 move closer together through the rotation of the hinge 313, reducing the overall structural volume and facilitating subsequent storage, handling, or refrigeration. This structure enables the foldable photovoltaic bracket 31 to have good structural adjustability and spatial adaptability while meeting normal use functions, which helps to improve the convenience of the entire foldable solar power generation device during transportation and storage.

[0029] like Figure 2 and Figure 6 As shown in a specific embodiment of this application, the first photovoltaic support 311 and / or the second photovoltaic support 312 include telescopic rods 314 and connecting beams 315. The number of telescopic rods 314 is at least two, and each end of the connecting beam 315 is connected to one telescopic rod 314, thereby forming a stable support frame. This structure can be configured into different forms such as a square frame or an H-shaped support. The telescopic rods 314 are designed to extend and retract along the arrangement direction of the photovoltaic panels 32. By adjusting the extension length of the telescopic rods 314, the overall dimensions of the first photovoltaic support 311 and / or the second photovoltaic support 312 can be changed to adapt to different installation spaces or usage requirements. The telescopic rods 314 adopt a two- or multi-section structure, and length adjustment is achieved through relative sliding between sections, thereby further improving the flexibility and applicability of length adjustment while ensuring structural strength.

[0030] The first photovoltaic support 311 and / or the second photovoltaic support 312 not only have a foldable function, but also integrate a telescopic and adjustable feature, so that the foldable photovoltaic support 31 can adjust the support size according to actual needs when unfolded, and effectively reduce the overall volume when folded, thereby further improving the structural adaptability and ease of use of the foldable solar power generation device.

[0031] like Figures 3 to 5 As shown in a specific embodiment of this application, the solar tracking drive assembly 2 includes a fixed base 21 and a movable base 22. The fixed base 21 can be mounted on the foldable bracket 1, providing a stable mounting foundation for the solar tracking drive assembly 2, ensuring that it can reliably support related components and maintain the stability of the overall structure during operation. The movable base 22 is installed in conjunction with the fixed base 21 and connected to the photovoltaic power generation module 3. Under the control of the drive mechanism, it can adjust its position or angle relative to the fixed base 21. The solar tracking drive assembly 2 utilizes the relative movement between the fixed base 21 and the movable base 22 to drive the photovoltaic power generation module 3 to adjust its angle according to the sun's trajectory, thereby achieving dynamic tracking of the direction of sunlight, improving the light reception efficiency of the photovoltaic power generation module 3, and ultimately enhancing the power generation performance of the overall power generation device.

[0032] like Figures 3 to 5As shown, in one specific embodiment of this application, the solar tracking drive assembly 2 includes a first drive member 23. The fixed end of the first drive member 23 is mounted on a fixed base 21 to provide basic support for the driving force. The first drive member 23 can rotate around the vertical direction, thereby driving the photovoltaic power generation module 3 to adjust its orientation in the horizontal plane, thus changing the orientation of the photovoltaic power generation module 3 to keep it relatively aligned with the position of the sun in the horizontal direction. Under the drive of the first drive member 23, the solar tracking drive assembly 2 can adjust the azimuth angle of the photovoltaic power generation module 3, that is, adjust the orientation of the photovoltaic power generation module 3 in the horizontal direction to track the horizontal movement trajectory of the sun at different times of the day, thereby improving the sunlight reception efficiency of the photovoltaic power generation module 3.

[0033] like Figures 3 to 5 As shown in a specific embodiment of this application, the light-tracking drive assembly 2 further includes a second drive member 24. The fixed end of the second drive member 24 is installed on the movable end of the first drive member 23, thereby further adjusting the tilt angle of the photovoltaic power generation assembly 3 based on the orientation adjustment completed by the first drive member 23. The movable end of the second drive member 24 can rotate around the horizontal direction and is drivenly connected to the movable seat 22. The second drive member 24 can drive the movable seat 22 and the photovoltaic power generation assembly 3 installed thereon to adjust the tilt angle relative to the horizontal direction, that is, change the angle of the photovoltaic power generation assembly 3 in the pitch direction to adapt to the changes in the altitude angle of the sun at different times of the day or in different seasons. Through this tilt angle adjustment function, the photovoltaic power generation assembly 3 can always maintain the optimal incident angle that is close to parallel with the sunlight, thereby improving the sunlight reception efficiency and enhancing the photovoltaic power generation performance.

[0034] The synergistic action of the first driving component 23 and the second driving component 24 helps to achieve adjustment of the photovoltaic power generation module 3 in two degrees of freedom: azimuth and elevation. This enables the entire power generation device to more accurately track the sun's trajectory, thereby improving overall power generation efficiency. This provides structural and functional support for the photovoltaic power generation device to achieve efficient light tracking under different times and locations. Specifically, the first driving component 23 and the second driving component 24 can be stepper motors or servo motors.

[0035] like Figures 3 to 5As shown, in one specific embodiment of this application, the light-tracking drive assembly 2 further includes a photosensitive unit 25 for sensing illuminance. This photosensitive unit 25 is positioned at the top of the light-tracking drive assembly 2, allowing it to fully receive natural light from above. The main function of the photosensitive unit 25 is to detect the intensity and direction of light in the environment in real time. By collecting this illuminance information, it provides the light-tracking drive assembly 2 with key input parameters for adjusting the orientation and tilt angle of the photovoltaic power generation module 3. The placement of the photosensitive unit 25 at the top of the light-tracking drive assembly 2 must minimize obstruction by surrounding structural components, thereby ensuring that the received light is as close as possible to the actual incident sunlight, improving the accuracy and representativeness of the photosensitive data.

[0036] By continuously monitoring illumination information through the photosensitive unit 25, the light-tracking drive assembly 2 can control the operating status of the first drive component 23 and the second drive component 24 according to changes in real-time illumination conditions, thereby achieving dynamic adjustment of the photovoltaic power generation assembly 3 in the azimuth and tilt directions. This structural design allows the entire light-tracking drive assembly 2 to further integrate illumination sensing functionality on the basis of mechanical drive capability, providing the necessary sensing foundation for the realization of automatic light-tracking function. Since the photosensitive unit 25 is an existing mature functional unit, its specific structural composition will not be described in detail in this application.

[0037] like Figures 3 to 5 As shown, in one specific embodiment of this application, the solar tracking drive assembly 2 further includes a control circuit board 26 and a battery. The control circuit board 26, as the core control unit of the solar tracking drive assembly 2, maintains a signal connection with the first drive element 23, the second drive element 24, and the photosensitive unit 25. It receives illumination information from the photosensitive unit 25 and generates corresponding control commands according to preset control logic or algorithms to adjust the operating state of the first drive element 23 and the second drive element 24. Through the coordinated control of the control circuit board 26, the first drive element 23 can drive the photovoltaic power generation assembly 3 to adjust its orientation in the horizontal direction, while the second drive element 24 can control the tilt angle change of the photovoltaic power generation assembly 3 in the vertical direction, thereby realizing the dynamic tracking of the solar trajectory by the photovoltaic power generation assembly 3 and improving its solar illumination reception efficiency.

[0038] The battery is electrically connected to the control circuit board 26, the first drive component 23, the second drive component 24, and the photosensitive unit 25 to provide the necessary power support for these components. The battery can be charged by the photovoltaic power generation module 3 when there is sunlight, or pre-stored under other power supply conditions to ensure that the light-tracking drive component 2 can maintain normal operation under various working conditions. By integrating the control circuit board 26 and the battery into the light-tracking drive component 2, this embodiment achieves the organic integration of drive, sensing, control, and power supply functions. This allows the light-tracking drive component 2 to not only have mechanical adjustment capabilities but also to autonomously respond and adjust according to real-time lighting conditions, improving the adaptability and reliability of the entire photovoltaic power generation device in unattended or automated operation scenarios.

[0039] like Figure 1 and Figure 2 As shown in a specific embodiment of this application, the foldable bracket 1 includes a support rod 11, legs 12, and diagonal braces 13. Multiple legs 12 are evenly distributed and sequentially arranged around the axial direction of the support rod 11. One end of each leg 12 is connected to the support rod 11 via a sliding fit, allowing the leg 12 to move along the axial direction of the support rod 11, thereby enabling the foldable bracket 1 to switch between an unfolded and folded state. The other end of the leg 12 is used to support the bracket on an external foundation, such as the ground, platform, or other mounting surface, providing a stable support foundation for the entire foldable bracket 1 and ensuring sufficient structural strength and stability when supporting the photovoltaic power generation module 3 and other related components.

[0040] One end of the diagonal brace 13 is hinged to the support rod 11, and the other end is hinged to the corresponding leg 12. When the foldable bracket 1 is in the unfolded state, the support rod 11, the leg 12, and the diagonal brace 13 cooperate to form a triangular structure, effectively resisting tipping loads and ensuring the safety and reliability of the entire bracket during operation. The foldable bracket 1 not only enables rapid unfolding and folding but also forms a stable support system in the unfolded state, providing a reliable load-bearing foundation for the overall structure of the photovoltaic power generation device. It also provides structural convenience for subsequent storage and transportation operations.

[0041] like Figure 1 and Figure 2As shown in a specific embodiment of this application, one end of the support rod 11 is provided with a socket, which is used to connect and position the light-tracking drive component 2 and the foldable bracket 1. The light-tracking drive component 2 can be installed on the support rod 11 by plugging into the socket, thereby forming a reliable connection between the light-tracking drive component 2 and the foldable bracket 1, providing a stable support foundation for the installation and operation of the photovoltaic power generation component 3. This plug-in structure makes the installation of the light-tracking drive component 2 simple and facilitates subsequent disassembly and maintenance, helping to improve the flexibility of the entire photovoltaic power generation device in assembly and use.

[0042] To further ensure the secure connection between the light-tracking drive assembly 2 and the support rod 11, the foldable bracket 1 also includes a locking member 14. One end of the locking member 14 penetrates the wall of the support rod 11 and extends into the insertion hole, forming a resisting action with the light-tracking drive assembly 2 after it is inserted into the insertion hole, thereby restricting the axial movement or loosening of the light-tracking drive assembly 2 within the insertion hole. The locking member 14 effectively prevents the light-tracking drive assembly 2 from shifting or loosening during operation due to vibration, external impact, or its own weight, thus improving the stability and reliability of the entire connection structure.

[0043] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
