The top of both sides of the photovoltaic panel connecting frame 23 is connected with rotating structures matched with the lifting drive structures, and the bottom of both sides of the photovoltaic panel connecting frame 23 is provided with adjustable support structures.

[0019] Workflow: When the photovoltaic bracket with folding function needs to be installed or deployed, first fix the two bottom supports 1 to the bottom of the support table 2, and place the entire device on the ground or other foundation structure, ensuring that the bottom support 1 is in stable contact with the ground. Then, by rotating the rotary base 5 at the top center of the support table 2, the mounting bracket 4 above it can be adjusted horizontally, so that the overall orientation of the photovoltaic panel 3 can be adjusted according to the change of the azimuth angle of the sun, to achieve the preliminary tracking of the direction of sunlight. After completing the horizontal positioning, start the lifting drive structure set on the other two sides of the top of the mounting bracket 4. The lifting drive structure, through the cooperation with the rotating structure on the side wall of the photovoltaic panel connecting frame 23, will push or pull the rotating structure when the lifting drive structure extends or retracts, thereby driving the photovoltaic panel connecting frame 23 to rotate around the rotating connection point on the top of the two sides of the mounting bracket 4, so as to realize the dynamic adjustment of the inclination angle of the photovoltaic panel 3, so that it can be adjusted to the best light receiving angle according to the change of season and sunlight height angle. In this process, the photovoltaic panel 3 is connected to the side wall of the photovoltaic panel connecting frame 23 in a detachable manner, which is convenient for later maintenance or replacement. At the same time, the adjustable support structure set on the bottom of both sides of the photovoltaic panel connecting frame 23 can be extended or retracted according to the actual use requirement, which is used to provide additional support force in strong wind or bad weather conditions, to enhance the stability of the overall structure. When transportation or temporary storage is needed, the lifting drive structure can be operated in reverse to gradually fold the photovoltaic panel connecting frame 23 to a parallel or attached state with the mounting bracket 4, and the rotary base 5 can also participate in the folding of the overall structure as part of the folding action, thereby significantly reducing the occupied space of the entire device, improving the convenience of transportation and storage, and when it is used again, it can be unfolded and locked according to the above process.
