[0015] A method for using a photovoltaic energy storage charging pile, the specific steps are as follows:

[0016] S1. First, start the first motor, which drives the screw to rotate. The rotation of the screw further drives the moving block to rise. The moving block is fixedly connected to the bent plate, so the bent plate will also rise. When the bent plate rises, it will drive the bottom shell and the first photovoltaic panel and the second photovoltaic panel installed on the bottom shell to move up, so that they are moved out of the protective shell;

[0017] S2. During the rising process of the moving block, the sliding column will slide in the sliding frame. When the sliding column slides to the turning point of the sliding frame, it will control the rotation of the rotating plate and the second gear. The second gear will then drive the toothed plate to slide on the sliding plate. The toothed plate meshes with the first gear, thereby driving the first round rod to rotate, thereby causing the bottom shell and the first photovoltaic panel and the second photovoltaic panel to fold ninety degrees. The second motor is started. The second motor drives the worm to rotate through the square rod. The worm then drives the worm wheel to rotate. The worm wheel is connected to the rotating shaft, thereby driving the second bevel gear to rotate. The second bevel gear meshes with the first bevel gear, driving the threaded rod to rotate. The rotation of the threaded rod causes the sliding block to move, thereby driving the connecting plate and the second photovoltaic panel to move, thereby achieving the spreading with the first photovoltaic panel and increasing the light energy absorption area.

[0018] S3. After the light energy absorbed by the photovoltaic panel is converted into electrical energy, the DC voltage is converted into AC power of the mains frequency through the photovoltaic inverter and stored in the battery module. Users can charge their electric vehicles through the charging gun of the charging pile;

[0019] S4. When it is nighttime or when it rains or in extreme weather, the first photovoltaic panel and the second photovoltaic panel need to be retracted. At this time, the above steps are performed in reverse order to shrink the first photovoltaic panel and the second photovoltaic panel first and then retract them into the protective shell. After the first photovoltaic panel and the second photovoltaic panel are fully retracted, the cover will naturally fall down and cover the top of the protective shell, providing protection for the photovoltaic panel, preventing it from being damaged in extreme weather and improving its protection capability.

[0020] The embodiments of the present invention have the following advantages:

[0021] 1. The photovoltaic panels are integrated into the top protective shell of the charging pile, realizing the integrated design of the photovoltaic panels and the charging pile, which greatly saves the floor space and avoids the waste of land resources caused by the separate installation of photovoltaic panels and charging piles in traditional photovoltaic energy storage charging piles, reduces the loss of long-distance power transmission, and improves energy utilization efficiency. The photovoltaic panels can receive sunlight to the maximum extent in the spread state, increase the light energy absorption area, and thus improve the photovoltaic energy storage efficiency;

[0022] 2. The photovoltaic panels can be automatically retracted into the protective shell, and the top of the protective shell is closed by a cover, which provides effective protection for the photovoltaic panels, avoids damage to the photovoltaic panels caused by extreme weather, and extends the service life of the equipment.

7. A method for using a photovoltaic energy storage charging pile, based on the photovoltaic energy storage charging pile according to claim 6, characterized in that: The specific steps are as follows: S1. First, start the first motor (20). The first motor (20) drives the screw rod (18) to rotate. The rotation of the screw rod (18) further drives the moving block (24) to rise. The moving block (24) is fixedly connected to the bent plate (25), so the bent plate (25) also rises accordingly. When the bent plate (25) rises, it drives the bottom shell (22) and the first photovoltaic panel (12) and the second photovoltaic panel (13) installed on the bottom shell (22) to move upward, so that they are moved out of the protective shell (7); S2. During the process of the moving block (24) rising, the slide column (31) slides in the slide frame (16). When the slide column (31) slides to the turning point of the slide frame (16), it controls the rotation of the rotating plate (30) and the second gear (29). The second gear (29) then drives the toothed plate (34) to slide on the slide plate (33). The toothed plate (34) meshes with the first gear (27), thereby driving the first round rod (26) to rotate, thereby causing the bottom shell (22) and the first photovoltaic panel (12) and the second photovoltaic panel (13) to be folded by 90 degrees, and the second motor (26) is started. 21), the second motor (21) drives the worm (43) to rotate through the square rod (19), the worm (43) in turn drives the worm wheel (45) to rotate, the worm wheel (45) is connected to the rotating shaft (39), and then drives the second bevel gear (38) to rotate, the second bevel gear (38) is meshed with the first bevel gear (37), drives the threaded rod (35) to rotate, the rotation of the threaded rod (35) causes the sliding block (36) to move, thereby driving the connecting plate (14) and the second photovoltaic panel (13) to move, so as to achieve spreading with the first photovoltaic panel (12), thereby increasing the light energy absorption area; S3, after the light energy absorbed by the photovoltaic panel is converted into electrical energy, the direct current voltage is converted into alternating current of the mains frequency through the photovoltaic inverter (5), and stored in the battery module (15), and the user can charge the electric vehicle through the charging gun (3) of the charging pile; S4. When it is nighttime or when it rains or encounters extreme weather, it is necessary to control the first photovoltaic panel (12) and the second photovoltaic panel (13) to be retracted. At this time, the above steps are reversed so that the first photovoltaic panel (12) and the second photovoltaic panel (13) are first retracted and then retracted into the protective shell (7). After the first photovoltaic panel (12) and the second photovoltaic panel (13) are fully retracted, the cover plate (11) will naturally fall down and cover the top of the protective shell (7), thereby providing protection for the photovoltaic panel, preventing it from being damaged in extreme weather, and improving the protection capability.
