The driving device 531 is configured to be retractable to provide power for the unfolding mechanism 5 .

[0056] See also Figure 4 and Figure 7 As shown, the other end of the first support rod 51 is rotatably connected to the middle part of the second support rod 52, that is, between the two ends of the second support rod 52, so as to realize the connecting rod movement between the first support rod 51 and the second support rod 52 with a simple and low-cost structural design. Furthermore, when the unfolding mechanism 5 is unfolded, the first support rod 51, the second support rod 52 and the column 1 form a triangle, which has strong structural stability and can provide stable support for the second photovoltaic unit 3.

[0057] In this embodiment, the unfolding mechanism 5 includes four first support rods 51, four second support rods 52 and a driving assembly 53. The four first support rods 51 are respectively connected to the four sides of the outer frame 5322. One driving assembly 53 can synchronously drive the four first support rods 51 to move. Each first support rod 51 drives a second support rod 52 to move, and each second support rod 52 drives a second photovoltaic unit 3 to move.

[0058] In this embodiment, each second photovoltaic unit 3 includes a second photovoltaic panel 30 , and the second photovoltaic panel 30 may be a frameless component or a framed component.

[0059] See also Figure 2 , Figure 6 , Fig.11 and Fig.12As shown, in this embodiment, the second photovoltaic unit 3 includes a base frame 31, the second photovoltaic panel 30 is fixedly mounted on the base frame 31, and the other end of the second support rod 52 is movably connected to the base frame 31.

[0061] See also Fig.13 , Fig.14 , Fig.18 and Fig. 20 As shown, the four second photovoltaic units 3 are rotatably connected to the four sides of the first photovoltaic unit 2 through the rotating connector 7.

The two are rotatably matched to achieve the rotational connection between the second photovoltaic panel 30 and the support frame 12.

[0062] Furthermore, since the rotation trajectory of the second photovoltaic unit 3 relative to the first photovoltaic unit 2 is to rotate downward 90° from a horizontal state to a vertical state, in order to avoid interference at the connection between the two during the rotation process, the first adapter 71 is arranged on the lower side of the connection between the two, that is, the position where the first adapter block 711 and the first adapter block 712 cooperate to rotate, which are respectively located near the bottom of the side edge of the support frame 12 and the bottom of the side edge of the frame of the second photovoltaic panel 30 in a horizontal state, so as to ensure the smooth rotation of the second photovoltaic panel 30.

[0063] See also Figures 15 to 19 As shown, in this embodiment, two second photovoltaic units 3 arranged opposite to each other are respectively connected to two third photovoltaic units 4, and the two third photovoltaic units 4 are rotatably connected to the two sides of the second photovoltaic unit 3 through a rotating connector 7. Each third photovoltaic unit 4 includes a third photovoltaic panel 40, and the third photovoltaic panel 40 can be a frameless component or a framed component. In this embodiment, the third photovoltaic panel 40 is a frameless component, and a rotating frame is fixed on its periphery to facilitate connection to the side of the second photovoltaic panel 30. The rotating connector 7 also includes a second adapter 72, and the two third photovoltaic units 4 are respectively connected to the two sides of the second photovoltaic unit 3 through a first adapter 71 and a second adapter 72. One of the first adapter block 711 and the first adapter block 712 of the first adapter 71 is fixed to the second photovoltaic panel 30, and the other is fixed to one of the third photovoltaic panels 40, and the two are rotated to cooperate to realize the rotation connection between one of the third photovoltaic panels 40 and the second photovoltaic panel 30. The second adapter 72 includes a second adapter block 721 and a second adapter block 722. One of the second adapter block 721 and the second adapter block 722 is fixed to the second photovoltaic panel 30, and the other is fixed to another third photovoltaic panel 40. The two are rotatably matched and limited by a locking member 723 to achieve a rotational connection between the other third photovoltaic panel 40 and the second photovoltaic panel 30.

[0064] Furthermore, since the rotation trajectory of the third photovoltaic unit 4 relative to the second photovoltaic unit 3 is to rotate 180° upward from a horizontal state to a reverse horizontal state, in order to avoid interference at the connection between the two during the rotation process, the first adapter 71 and the second adapter 72 are both arranged on the lower side of the connection between the two, that is, the position where the first adapter block 711 and the first adapter block 712 cooperate to rotate, and the position where the second adapter block 712 and the second adapter block 722 cooperate to rotate, are respectively located at a position near the bottom of the side edge of the frame of the second photovoltaic panel 30 in a horizontal state, and a position near the bottom of the side edge of the rotating frame of the third photovoltaic panel 40 in a horizontally unfolded state, so as to ensure the smooth rotation of the third photovoltaic panel 40.

[0065] Furthermore, since two of the relatively arranged second photovoltaic units 3 are respectively connected to two third photovoltaic units 4, the two third photovoltaic units 4 can be respectively rotated and folded to a state of being folded with the second photovoltaic unit 3. In order to avoid interference between the two third photovoltaic units 4 during folding, resulting in insufficient folding, the rotation radius of the second adapter 72 is set to be larger than the rotation radius of the first adapter 71, and the difference between the rotation radii of the two is not less than the thickness of the third photovoltaic unit 4. When folding, the third photovoltaic unit 4 connected to the second photovoltaic unit 3 through the first adapter 71 is first rotated and folded, and then the third photovoltaic unit 4 connected to the second photovoltaic unit 3 through the second adapter 72 is rotated and folded, so as to ensure that the two third photovoltaic units 4 are fully folded with the second photovoltaic unit 3 in the thickness direction when folded.

[0066] See also Figure 2 , Figure 5 , Fig.21 and Fig. 22 As shown, the support connector 6 includes a first connection hole 61 and a second connection hole 62, wherein the first connection hole 61 is connected to the lower surface of the frame of the second photovoltaic panel 30. When the third photovoltaic panel 40 is in a folded state, the support connector 6 rotates around the first connection hole 61 until the whole is folded under the second photovoltaic panel 30; when the third photovoltaic panel 40 is in an unfolded state, the support connector 6 rotates around the first connection hole 61 until it partially fits the lower surface of the frame of the third photovoltaic panel 40, and is fixedly connected to the lower surface of the frame of the third photovoltaic panel 40 through the second connection hole 62. In this way, the support and fixation of the third photovoltaic panel 40 is achieved with a simple and low-cost structure, and the occupied space of the entire photovoltaic support system when folded can be further reduced.

[0067] See also Figure 1 , Figure 2 , Fig. 20 , Fig.21 , Fig.23 , Fig.24 and Fig.25 As shown, the four-sided foldable photovoltaic support system of this embodiment can quickly unfold the photovoltaic panels when power generation is needed, and the unfolding mechanism 5 flips the second photovoltaic unit 3 to the horizontal, and the driving component 53 drives the first support rod 51 and the second support rod 52 to perform connecting rod movement, and the four second photovoltaic units 3 on the four sides are flipped to the required angle and then fixed; then the third photovoltaic unit 4 folded with the second photovoltaic unit 3 is turned to the side of the second photovoltaic unit 3 and kept parallel with it, and then the supporting connector 6 is rotated and extended from the bottom of the second photovoltaic unit 3 to fix the second photovoltaic unit 3 and the third photovoltaic unit 4, so that the deployment of a total of nine photovoltaic panels on the four sides and in the middle is completed.

[0068] When not in use, the photovoltaic panel can be quickly folded up; loosen the connection between the supporting connector 6 and the third photovoltaic unit 4, rotate the third photovoltaic unit 4 upward relative to the second photovoltaic unit 3 to a state of folding with the second photovoltaic unit 3, and rotate the supporting connector 6 around the first connection hole 61 to be stored under the second photovoltaic unit 3; then the unfolding mechanism 5 flips the photovoltaic panel horizontally unfolded on all sides to a vertical state, and the driving assembly 53 drives the first support rod 51 and the second support rod 52 to perform connecting rod movement, flips the four second photovoltaic units 3 on all sides to a vertical state and then fixes them, and the surrounding photovoltaic panels and the first photovoltaic unit 2 in the middle surround the other components, and the overall shape is roughly formed into a cube, that is, the nine photovoltaic panels are stored and folded up, which significantly reduces the occupied space and makes the deployment of photovoltaic panels more flexible. Whether in a fixed place or a mobile occasion, the photovoltaic support system can quickly adjust the number and layout of photovoltaic panels according to actual needs.

[0069] In other embodiments, the nine photovoltaic panels may have different layouts. The four second photovoltaic units 3 are respectively connected to a third photovoltaic unit 4, and the four third photovoltaic units 4 are rotatably connected to the same side of the four second photovoltaic units 3 in a clockwise or counterclockwise direction through adapter connectors 7. At this time, in order to ensure the maximum folding degree and minimum occupied space when the third photovoltaic unit 4 and the second photovoltaic unit 3 are folded, the first adapter 71 is used to connect the second photovoltaic unit 3 and the third photovoltaic unit 4.

[0070] At the same time, the photovoltaic support system of this embodiment also includes a control box 9 arranged below the column 1, which is used to control the operation of the entire photovoltaic support system. The control box 9 is equipped with a control module and an energy storage module. Furthermore, the control module can also be connected to the control background for communication, and can remotely adjust the flip assembly and the telescopic assembly to reduce manual intervention and reduce the risk of equipment damage caused by improper human operation. It can also realize remote monitoring and maintenance of photovoltaic panels through an intelligent control system, further reducing maintenance costs.

[0071] In summary, compared with the prior art, the four-sided foldable photovoltaic support system of the present invention has the following advantages: an unfolding mechanism 5 is set, and the unfolding mechanism 5 includes a first support rod 51, a second support rod 52 and a driving assembly 53.
