[0020] Please see Figure 1-3A photovoltaic panel support with folding function includes a base 7, multiple support frames 1 arranged at intervals on the upper side of the base 7, a folding drive mechanism 2 and a sliding guide mechanism 3 arranged at intervals on the multiple support frames 1, and multiple bidirectional folding photovoltaic modules arranged between the folding drive mechanism 2 and the sliding guide mechanism 3. The multiple bidirectional folding photovoltaic modules are arranged at intervals. The bidirectional folding photovoltaic module includes a circumferential shaft connecting mechanism, two mounting folding mechanisms 5 connected to the circumferential shaft connecting mechanism and arranged symmetrically along it, a photovoltaic panel 30 on the upper surface of the mounting folding mechanism 5, a buffer protection mechanism on the lower side of the mounting folding mechanism 5, and a rotating connecting mechanism on one side of the mounting folding mechanism 5. One end of the rotating connecting mechanism is connected to one side of the folding drive mechanism 2, and the other end of the rotating connecting mechanism is slidably engaged with one side of the sliding guide mechanism 3. Multiple reinforcing limit bars 4 are provided between the sliding guide mechanism 3 and the folding drive mechanism 2, and the reinforcing limit bars 4 are located above the circumferential shaft connecting mechanism.

[0021] The mounting folding mechanism 5 includes a mounting groove 6 and multiple positioning plates 8 connected to the mounting groove 6. The photovoltaic panel 30 is embedded on the upper side of the mounting groove 6, and the lower sides of the multiple positioning plates 8 are tightly attached to the upper side of the photovoltaic panel 30.

[0022] The buffer protection mechanism includes guide posts 11 connected to the four corners of the lower side of the mounting groove 6, multiple first springs 10 connected to the lower side of the mounting groove 6 and arranged in a rectangular array between the four guide posts 11, a buffer protection plate 9 connected to one end of the multiple first springs 10, a connecting nut 12 threaded to one end of the guide post 11, and a second spring 13 sleeved on the outer wall of the guide post 11. The connecting nut 12 abuts against the outer side of the buffer protection plate 9. The two ends of the second spring 13 are respectively connected to the buffer protection plate 9 and the opposite side of the mounting groove 6. One end of the first spring 10 is connected to one side of the buffer protection plate 9. One end of the guide post 11 passes through and extends to one side of the buffer protection plate 9.

[0023] The circumferential shaft connection mechanism includes a connecting rod 22, a plurality of first rotating blocks 23 and a plurality of second rotating blocks 24 rotatably connected to the connecting rod 22 and spaced apart. One end of each of the first rotating blocks 23 and one end of each of the second rotating blocks 24 are respectively connected to the opposite side of the two mounting slots 6 contained in each of the two mounting folding mechanisms 5. The connecting rod 22 provides a mounting base for the plurality of first rotating blocks 23 and second rotating blocks 24, ensuring the continuity of movement between the components. The plurality of first rotating blocks 23 and second rotating blocks 24 are rotatably connected to the connecting rod 22 at intervals, which not only realizes flexible rotation in the circumferential direction, but also evenly distributes the force during movement, avoids local stress concentration, and enhances the overall stability of the mechanism.

[0024] The rotating mechanism includes a fixed post 25 and a sleeve 26 that is fitted onto the outside of the fixed post 25 and rotatably engaged with the outer wall of the fixed post 25. The sleeve 26 is connected to the other side of the mounting groove 6. The fixed post 25 serves as a supporting foundation, providing a rotation axis for the sleeve 26 and ensuring the stability of its rotational movement. The rotatable engagement design between the sleeve 26 and the outer wall of the fixed post 25 not only allows the sleeve 26 to rotate around the fixed post 25, but also reduces swaying and offset during rotation through their close contact.

[0025] The folding drive mechanism 2 includes a mounting housing 16, a strip opening 17 on one side of the mounting housing 16, multiple side plates 18 connected to the inside of the mounting housing 16 and spaced apart, multiple bidirectional screws 20, two threaded blocks 21 threadedly engaged with the bidirectional screws 20, and a drive motor 19 mounted at one end of the mounting housing 16. The output end of the drive motor 19 is connected to one end of a bidirectional screw 20 via a coupling. Two adjacent bidirectional screws 20 are connected via couplings. One end of the two bidirectional screws 20 located at both ends is rotatably connected to the inside of the mounting housing 16 via bearings. Multiple bidirectional screws 20 are rotatably connected to multiple side plates 18 via bearings. One end of a fixing post 25 passes through the strip opening 17 and is connected to one side of the corresponding threaded block 21. One end of a reinforcing limit stop 4 is connected to one side of the mounting housing 16.

[0026] The sliding guide mechanism 3 includes a guide plate 27, a groove 28 formed on one side of the guide plate 27, and multiple sliders 29 slidably connected in the groove 28. The other end of the fixed column 25 is connected to one side of the corresponding slider 29. The other end of the reinforcing limit stop 4 is connected to one side of the guide plate 27, and the reinforcing limit stop 4 is located above the connecting rod 22.

[0027] The support frame 1 includes two uprights 14 connected to the upper side of the base 7 and spaced apart, and a reinforcing crossbar 15 connecting the two uprights 14. The upper end of one upright 14 is connected to the lower side of the mounting housing 16, and the upper end of the other upright 14 is connected to the lower side of the guide plate 27. The base 7 provides a support platform for multiple support frames 1; the two spaced uprights 14, together with the reinforcing crossbar 15, enhance the overall rigidity and deformation resistance of the frame, reducing the risk of swaying and displacement.

[0028] A support frame 1 includes uprights 14, on one side of which wind speed sensors 31 and controllers 32 are arranged at intervals. Both the wind speed sensors 31 and the drive motor 19 are electrically connected to the controller 32.

[0029] Working process and principle: When installing multiple photovoltaic panels 30 and brackets, the photovoltaic panels 30 need to be embedded into the corresponding mounting slots 6. Then, multiple positioning plates 8 are bolted to the mounting slots 6. The photovoltaic panels 30 are positioned in the mounting slots 6 by these positioning plates 8, thereby completing the installation of the photovoltaic panels 30.

[0030] In actual use of the bracket, if strong winds occur and the wind speed exceeds the preset threshold of the wind speed sensor 31, the wind speed sensor 31 transmits this information to the controller 32. After receiving the information, the controller 32 controls the drive motor 19 to start. After the drive motor 19 starts, it drives multiple interconnected bidirectional screws 20 to start rotating. As the bidirectional screws 20 rotate, the two threaded blocks 21 on them move closer to each other along the bidirectional screws 20. The fixing posts 25 also move closer to each other. At this time, the slider 29 connected to the other end of the fixing post 25 slides in the slide groove 28. With the cooperation of the sleeve 26 sleeved on the outer wall of the fixing post 25, multiple second rotating blocks 24 connected to one side of the mounting groove 6 rotate on the connecting rod 22. At the same time, multiple first rotating blocks 23 connected to the other side of the mounting groove 6 also rotate synchronously on the connecting rod 22. Under the blocking and limiting action of the reinforcing limit bar 4, the connecting rod 22 moves downward, thereby causing the two mounting grooves 6 to fold relative to each other, so that the two photovoltaic panels 30 are located between the two mounting grooves 6. This design provides protection for the photovoltaic panels 30 during windy weather. Simultaneously, the multiple sets of folded mounting slots 6 reduce the contact area with strong winds, thereby mitigating potential damage to the support structure and the multiple photovoltaic panels 30. When the wind direction changes, the buffer plate 9, under the combined action of multiple first springs 10, four guide posts 11, and second springs 13, further cushions and protects the folded mounting slots 6 and the photovoltaic panels 30.

[0031] In summary, this support structure can automatically and symmetrically fold multiple photovoltaic panels 30 in windy weather. After folding, the mounting groove 6 protects the photovoltaic panels 30 and reduces the contact area between the panels and the wind, thus mitigating the damage to the panels and the entire support structure. Furthermore, when the wind direction changes, the support structure provides cushioning protection for the folded photovoltaic panels 30, preventing damage from debris carried by the wind.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
