[0036] See also Figure 2 The movable frame 2 includes two opposite first sides 21 and two opposite second sides 22. The first sides 21 are vertically connected to the second sides 22. The two first sides 21 and the two second sides 22 together form a square frame, and the photovoltaic module is installed on the inner side of the square frame.

[0037] See also Figure 2 The retractable photovoltaic support further includes a sliding assembly 3, which connects the mobile frame 2 and the base 1. Under the action of an external force, the mobile frame 2 can slide relative to the base 1, so that the photovoltaic components in the mobile frame 2 can be retracted to the base 1 or extended outward from the base 1. In some embodiments, see Figure 4 The sliding assembly 3 includes a first slide 31, a second slide 32 and a third slide 33. The first slide 31 is fixedly connected to the moving frame 2, the second slide 32 is fixedly connected to the base 1, and the third slide 33 is an intermediate slide rail and is located between the first slide 31 and the second slide 32.

The third slider 33 includes a third base 331, a fifth curved portion 332, a sixth curved portion 333, a seventh curved portion 334, and an eighth curved portion 335. The fifth curved portion 332 and the sixth curved portion 333 are respectively connected to the upper and lower ends of the third base 331. The seventh curved portion 334 is connected to the fifth curved portion 332, and the eighth curved portion 335 is connected to the sixth curved portion 333. The first base 311 is connected to the movable frame 2, the second base 321 is connected to the base 1, the first curved portion 312 and the seventh curved portion 334, and the second curved portion 313 and the eighth curved portion 335 all enclose a space for accommodating the first roller 34, while the third curved portion 322 and the fifth curved portion 332, and the fourth curved portion 323 and the sixth curved portion 333 all enclose a space for accommodating the second roller 35. To prevent the first roller 34 and the second roller 35 from falling out of the space, stoppers can be provided at both ends of the first slider 31 and the third slider 33.

[0039] In another embodiment, the sliding assembly 3 can eliminate the third slide 33, the first roller 34 and the second roller 35. One of the first slide 31 and the second slide 32 can be set as a slide rail and the other can be set as a slide seat, so that the two can slide relative to each other.

[0040] See also Figure 1 The retractable photovoltaic bracket also includes a driving component 4, which is connected to the base 1, and the movable frame 2 is connected to the output end of the driving component 4. The driving component 4 can drive the movable frame 2 to move along the second slide 32, so that the photovoltaic components in the movable frame 2 are automatically retracted toward the inside of the base 1 or expanded toward the outside of the base 1.

[0041] See also Figure 2 and Figure 3 The driving assembly 4 includes a driving member 41, a driving shaft 42, a driven shaft 43 and a transmission member 44. The driving member 41 is fixedly connected to the base 1. The driving shaft 42 and the driven shaft 43 are both rotatably connected to the base 1. The driving shaft 42 and the driven shaft 43 are arranged at intervals along the length direction L of the second slide 32. The transmission member 44 is sleeved on the driving shaft 42 and the driven shaft 43. The moving frame 2 is connected to the transmission member 44. The driving member 41 can drive the driving shaft 42 to rotate to drive the transmission member 44 to revolve, and the moving frame 2 is driven to slide relative to the base 1 through the transmission member 44.

[0042] In some embodiments, the conveyor 44 is a chain, correspondingly, see Figure 3 The driving shaft 42 and the driven shaft 43 each include a shaft body 421 and a sprocket 422 sleeved on the outer periphery of the shaft body 421, and the chain cooperates with the sprocket 422. Of course, in other embodiments, the transmission member 44 can also be a belt. Accordingly, the driving shaft 42 and the driven shaft 43 each include a shaft body 421 and a pulley sleeved on the outer periphery of the shaft body 421.

[0043] The two first sides 21 are fixedly connected to the first slide 31 , and the two cross beams 11 are fixedly connected to the second slide 32 . The first slides 31 of the two first sides 21 are slidably matched with the two second slides 32 .

[0044] See also Figure 3 The driving shaft 42 and the driven shaft 43 connect the two crossbeams 11. Sprockets 422 are provided at both ends of the shaft bodies 421 of the driving shaft 42 and the driven shaft 43. The two first edges 21 are respectively connected to the two transmission members 44. The driving member 41 drives the driving shaft 42 to rotate, causing the two transmission members 44 to revolve. These two transmission members 44 drive the moving frame 2 to move relative to the base 1, and the force on both sides of the moving frame 2 is evenly distributed.

[0045] See also Figure 3 The drive assembly 4 also includes a transmission chain 45 and a tensioning pulley 46. The driving member 41 is fixed to the inner side of a beam 11. The shaft body 421 of the driving shaft 42 is also sleeved with an outer sprocket 423. The outer sprocket 423 is located on the outer side of the beam 11 to which the driving member 41 is fixed. The transmission chain 45 is sleeved on the sprocket at the output end of the driving member 41, the tensioning pulley 48 and the outer sprocket 423 of the driving shaft 42.

[0046] The first side 21 of the moving frame 2 is directly or indirectly connected to the conveying member 44. Figure 8 Indirect connection refers to the connection between the first side 21 and the transmission member 44 via the connecting member 23. The connecting member 23 has a U-shaped structure, and the transmission member 44 is configured as a double-row chain. The U-shaped structure and the double-row chain are connected to each other, which facilitates the stable movement of the movable frame 2. In other embodiments, the first side 21 of the movable frame 2 and the transmission member 44 can also be directly connected. The end of the first side 21 is integrally bent to form a U-shaped structure, which is connected to the double-row chain via the U-shaped structure.

[0047] For details, see Figure 8The first side 21 extends beyond the second side 22 along its length, and the portion extending beyond the second side 22 is an extension portion 211. One end of the connector 23 is fixed to the extension portion 211, and the other end of the connector 23 is fixed to the conveyor member 44. When the movable frame 2 is extended outward, the connector 23 moves with the conveyor member 44 to the position of the driving shaft 42 or the driven shaft 43 and cannot move further. By extending the first side 21 toward the conveyor member 44 for a certain distance, more of the photovoltaic modules within the movable frame 2 can be extended outward when the connector 23 is at its terminal position.

[0048] In some embodiments, see Figure 5 The moving frame 2 includes a first moving frame 2a and a second moving frame 2b, and the first moving frame 2a and the second moving frame 2b are both fixed with a first slide 31. Figure 5 and Figure 11 The second slide 32 includes an upper slide 32a and a lower slide 32b, each of which is fixed to each crossbeam 11. Along the height direction (vertical direction) of the base 1, the upper slide 32a is located above the conveying member 44, and the lower slide 32b is located below the conveying member 44. The upper slide 32a slidably engages with the first slide 31 fixed to the first movable frame 2a, while the lower slide 32b slidably engages with the first slide 31 fixed to the second movable frame 2b.

[0049] In some embodiments, in the expanded state, along the length direction (left and right direction) of the second slide 32, the first movable frame 2a is located on the left side of the second movable frame 2b; during the recovery process, the first movable frame 2a moves from the left side to the right side of the conveying member 44, and the second movable frame 2b moves from the right side to the left side of the conveying member 44.

[0050] In some other possible embodiments, in the expanded state, along the length direction (left-right direction) of the second slide 32, the first movable frame 2a is located on the right side of the second movable frame 2b; during the recycling process, the first movable frame 2a moves from the right side to the left side of the conveying member 44, and the second movable frame 2b moves from the left side to the right side of the conveying member 44.

[0051] The first movable frame 2a and the second movable frame 2b each include two opposing first sides 21, and the first sides 21 of the first movable frame 2a and the first sides 21 of the second movable frame 2b are respectively connected to opposite sides of the conveyor 44. When the conveyor 44 rotates, it drives the first movable frame 2a and the second movable frame 2b to move in opposite directions, respectively, so that the photovoltaic modules in the first movable frame 2a and the photovoltaic modules in the second movable frame 2b are simultaneously retracted into the base 1 or simultaneously deployed to the sides of the base 1.

[0052] Along the height direction of the base 1, the first movable frame 2a and the second movable frame 2b are located on the same side of the fixed frame 5. In some embodiments, see Figure 5Along the height direction of the base 1, the fixed frame 5 is located above the first movable frame 2a and the second movable frame 2b, and the first movable frame 2a is located above the second movable frame 2b. Of course, in other embodiments, along the height direction of the base 1, the fixed frame 5 can also be located below the first movable frame 2a and the second movable frame 2b. It should be noted that the height direction of the base 1 is perpendicular to the length direction L of the second slider 32.

[0053] In short, after the first movable frame 2a and the second movable frame 2b are retracted into the base 1, the photovoltaic components in the fixed frame 5 and the photovoltaic components in the first movable frame 2a and the second movable frame 2b can overlap each other, reducing the occupied space and facilitating transportation; when needed, the driving component 4 controls the first movable frame 2a and the second movable frame 2b to expand to both sides relative to the base 1, without the need for on-site assembly, saving manpower, and enabling rapid deployment of a large number of photovoltaic components in a short time. In addition, it is also convenient for deployment in limited space, thereby improving space utilization.

[0054] See also Figure 6 The retractable photovoltaic bracket includes a limit switch 6, which is fixed to the base 1. The limit switch 6 includes a touch rod 61. When the moving frame 2 moves, the touch rod 61 collides with the circuit to disconnect the circuit, thereby stopping the moving frame 2 from moving, limiting the expansion distance and ensuring safety.

[0055] In some embodiments, the photovoltaic support further includes a controller for controlling the start and stop of the photovoltaic support. The controller is electrically connected to the driver 41 and the limit switch 6. When the movable frame 2 triggers the limit switch 6, the controller sends a signal to the controller, which controls the movable frame 2 to stop moving based on the signal.

[0056] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. The understanding of the present invention should be based on technical personnel in the relevant technical field. Although this specification has described the present invention in detail with reference to the above embodiments, ordinary technical personnel in the field should understand that technical personnel in the relevant technical field can still modify or replace the present invention with equivalents, and all technical solutions and improvements that do not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
