Figure 2 This is a schematic structural diagram of the umbrella structure 30 in an unfolded state at one angle according to an embodiment of the present invention. Figure 3 This is a schematic structural diagram of the umbrella structure 30 in its unfolded state from another angle according to one embodiment of the present invention. Figure 4 yes Figure 2 A schematic enlarged view of part A in the diagram. Figure 5 This is a schematic structural diagram of a photovoltaic sunshade 100 with the support 10 concealed, according to one embodiment of the present invention. Figure 6 This is a schematic connection diagram of the umbrella canopy structure 30 and the telescopic component 22 according to an embodiment of the present invention.

[0025] like Figures 1 to 6As shown, in a specific embodiment, the photovoltaic sunshade 100 includes a support 10, an umbrella structure 30, and a retractable assembly 20. The umbrella structure 30 includes multiple movably connected umbrella panels 32 and thin-film photovoltaic cells 31 covering each umbrella panel 32. The retractable assembly 20 includes a telescopic assembly 22 disposed on the support 10 and two push-pull plates 21 connected to opposite sides of the telescopic assembly 22. The telescopic assembly 22 includes a cross-arranged and telescopic first telescopic bracket 221 and a second telescopic bracket 222, with the first telescopic bracket 221 and the second telescopic bracket 222 connected to the same side of the multiple umbrella panels 32. The end of the first telescopic bracket 221 has a sliding groove 226, and the opposite ends of the sliding groove 226 are respectively provided with positioning grooves 227. The end of the second telescopic bracket 222 has a limiting post 225 that slides along the sliding groove 226. When an external force pushes or pulls the push-pull plates 21, it drives the first telescopic bracket 221 and the second telescopic bracket 222 to extend or retract, thereby causing the multiple umbrella panels 32 to retract and unfold. During the folding and unfolding process, the limiting post 225 slides along the slide groove 226, and when the multi-section umbrella panel 32 is in the folded and unfolded states, the limiting post 225 is positioned in the two positioning grooves 227 respectively to limit the umbrella structure 30. Here, when the umbrella structure 30 is in the folded state, the umbrella panel 32 and the thin-film photovoltaic cell 31 are in a folded state.

[0026] This embodiment, through the design of the sliding groove 226, the positioning groove 227 and the limiting post 225, can limit the umbrella structure 30 whether it is in the closed or open state, which can prevent the umbrella structure 30 from shaking or accidentally opening and closing, and improve the reliability of the photovoltaic sunshade umbrella 100.

[0027] In some embodiments, the first telescopic bracket 221 includes a plurality of first chain plates 223 rotatably connected in sequence. The first chain plates 223 connected to the push-pull plate 21 are provided with sliding grooves 226 and positioning grooves 227. The second telescopic bracket 222 includes a plurality of second chain plates 224 rotatably connected in sequence. The second chain plates 224 connected to the push-pull plate 21 are provided with limiting posts 225. Each umbrella panel 32 is connected to a second chain plate 224. It can be understood that this embodiment only requires limiting the ends of the first telescopic bracket 221 and the second telescopic bracket 222 to prevent accidental extension and retraction of the telescopic assembly 22.

[0028] In some embodiments, two adjacent first chain plates 223 and two adjacent second chain plates 224 are connected by hinge shafts to achieve a rotatable connection. In addition, the outermost first chain plate 223 and second chain plate 224 are also connected to the push-pull plate 21 by hinges.

[0029] In some embodiments, the number of first chain plates 223 and second chain plates 224 is 16. In other embodiments, the number of first chain plates 223 and second chain plates 224 can be determined according to specific needs. When the umbrella structure 30 is in the unfolded state, the outermost first chain plate 223 forms a 60° angle with the push-pull plate 21, and the outermost second chain plate 224 forms a 60° angle with the push-pull plate 21.

[0030] In some embodiments, the two positioning grooves 227 are located on the same side of the slide groove 226. In other embodiments, the two positioning grooves 227 may also be located on different sides of the slide groove 226, which can be determined according to design requirements.

[0031] In some embodiments, the two positioning grooves 227 are respectively a first positioning groove and a second positioning groove. The first positioning groove is located at the top end of the slide groove 226, and the second positioning groove is located at the bottom end of the slide groove 226. When the umbrella structure 30 is in the closed state, the limiting post 225 is located in the first positioning groove. See [reference needed]. Figure 5 When the umbrella structure 30 is in the unfolded state, the limiting post 225 is located in the second positioning groove, see [reference]. Figure 4 Here, the shape of the limiting post 225 is adapted to the shape of the positioning groove 227 to ensure that the limiting post 225 can smoothly enter the positioning groove 227. The extension length of the slide groove 226 can be determined according to the moving distance of the push-pull plate 21 when it switches from the unfolded state to the retracted state. The longer the moving distance of the push-pull plate 21, the longer the extension length of the slide groove 226.

[0032] In some embodiments, the number of telescopic components 22 is two sets, with the two sets of telescopic components 22 located on both sides of the umbrella structure 30 and connected to the umbrella panel 32. Compared to the technical solution of designing only one set of telescopic components 22 under the umbrella structure 30, this can improve the stability of the umbrella structure 30 during the opening and closing process. Here, it is equivalent to the telescopic components 22 and the umbrella structure 30 closing and opening synchronously.

[0033] In some embodiments, the bracket 10 includes a support frame 11, a support beam 14, and a bendable linkage assembly 23. The support beam 14 is vertically mounted on the support frame 11. A push-pull plate 21 is provided at each opposite end of the linkage assembly 23. The telescopic component 22 and the linkage assembly 23 are distributed vertically. When an external force pushes or pulls the push-pull plate 21, it drives the linkage assembly 23 to bend, thereby adjusting the distance between the two push-pull plates 21. It can be understood that the push-pull plate 21 is connected to the bracket 10 via the linkage assembly 23.

[0034] In some embodiments, the linkage assembly 23 includes a plurality of links rotatably connected in sequence. During retraction, the included angle between two adjacent links gradually decreases to reduce the distance between the two push-pull plates 21. During extension, the included angle between two adjacent links gradually increases to increase the distance between the two push-pull plates 21. Here, when the included angle between two adjacent links gradually decreases, the two links move closer to each other. When the included angle between two adjacent links gradually increases, the two links move further apart. The push-pull plates 21 are the direct force-bearing components of the retraction assembly 20, receiving externally applied horizontal forces and driving the entire linkage assembly 23. Here, the support beam 14 is located in the middle of the linkage assembly 23, and its two ends are hinged to the links on both sides respectively. The support beam 14 provides a stable rotation fulcrum for the linkage assembly 23.

[0035] In some embodiments, a connecting rod assembly 30 is provided on each of the opposite sides of the umbrella panel 32, which can improve stability during the closing and unfolding processes.

[0036] In some embodiments, the bracket 10 further includes an umbrella cap 13 mounted on the support beam 14, and an umbrella canopy structure 30 disposed between the umbrella cap 13 and the support beam 14. The umbrella cap 13 has a receiving space on the side facing the umbrella canopy structure 30. When the umbrella canopy structure 30 is in the folded state, it is folded into the receiving space, providing dust protection. Here, the support frame 11 is arranged vertically, the support beam 14 is mounted on the top of the support frame 11 and extends along a first horizontal direction, and the umbrella cap 13 is mounted on the top of the support beam 14. When the umbrella canopy structure 30 is in the unfolded state, it extends along a second horizontal direction, which is perpendicular to the first horizontal direction.

[0037] Specifically, when the push-pull plate 21 is pushed towards the center of the umbrella structure 30, the push-pull plate 21 causes the umbrella structure 30 to close, specifically causing the connecting rod assembly 23 to fold, compressing the first chain plate 223. The limiting post 225 on the second chain plate 224 is compressed by the second positioning groove at the bottom of the slide groove 226, moving along the slide groove 226 until the limiting post 225 slides into the first positioning groove at the top of the slide groove 226. At the same time, as the limiting post 225 slides along the slide groove 226, it forces the first chain plate 223 to rotate, thereby sequentially pushing all subsequent first chain plates 223 and second chain plates 224 to tighten through each hinge point until the umbrella structure 30 is closed. When the push-pull plate 21 is pulled towards the outside of the umbrella structure 30, the telescopic assembly 22 unfolds synchronously under the traction of the push-pull plate 21 and the connecting rod assembly 23, in the opposite principle to the closing process. When the closing and unfolding actions are completed, the limiting post 225 is respectively engaged in the two positioning grooves 227, thereby achieving the effect of fixing the umbrella structure 30.

[0038] In some embodiments, each thin-film photovoltaic cell 31 has a positive electrode tab and a negative electrode tab. Multiple thin-film photovoltaic cells 31 have positive electrode tabs arranged in rows, and multiple thin-film photovoltaic cells 31 have negative electrode tabs arranged in rows. The connecting rod assembly 23 has a first wire-passing hole extending in a first direction, the same as the opening / closing direction of the umbrella structure 30. The support beam 14 has a second wire-passing hole extending in a second direction, and the support frame 11 has a third wire-passing hole extending in a third direction. The first, second, and third directions are perpendicular to each other. Multiple rows of positive electrode tabs are electrically connected via a positive electrode busbar, and multiple rows of negative electrode tabs are electrically connected via a negative electrode busbar. Both the positive and negative electrode busbars pass sequentially through the first, second, and third wire-passing holes.

[0039] This embodiment avoids power line leakage by introducing the positive and negative busbars into the connecting rod assembly 23, the support beam 14, and the support frame 11, thereby improving electrical safety and enhancing the aesthetics of the photovoltaic sunshade 100.

[0040] Specifically, the thin-film photovoltaic cell 31 is rectangular, with the positive and negative electrode tabs located on opposite sides of the cell. When the umbrella structure 30 is in the unfolded state, adjacent thin-film photovoltaic cells 31 are arranged at a 120° angle. In other embodiments, the angle between adjacent thin-film photovoltaic cells 31 can be determined according to specific design requirements.

[0041] In some embodiments, the bracket 10 further includes a counterweight base 12, with the support beam 14 and the counterweight base 12 respectively disposed at both ends of the support frame 11. The counterweight base 12 is provided with a wiring interface, and both the positive and negative busbars are connected to the wiring interface. This embodiment improves the stability of the photovoltaic sunshade 100 by providing the counterweight base 12.

[0042] In some embodiments, a pre-defined spacing region is provided at the adjacent edges of two thin-film photovoltaic cells 31 on two adjacent umbrella panels 32. This embodiment arranges the two adjacent thin-film photovoltaic cells 31 separately, which can prevent the adjacent thin-film photovoltaic cells 31 from interfering with each other during the closing of the umbrella structure 30.

[0043] In some embodiments, the retraction components 20 are evenly arranged on opposite sides of the support 10, thereby providing stability during the retraction process.

[0044] In some embodiments, the present invention also provides an energy storage system, including a photovoltaic sunshade 100, a micro-inverter, and / or an energy storage power supply as described in any of the above embodiments. The micro-inverter is connected to a positive electrode via a positive bus and to a negative electrode via a negative bus, and is used to convert the direct current (DC) power from the thin-film photovoltaic cells 31 into alternating current (AC). The energy storage power supply is connected to a positive electrode via a positive bus and to a negative electrode via a negative bus, and is used to store the DC power converted from solar energy by the thin-film photovoltaic cells 31. Details regarding the photovoltaic sunshade 100 are omitted here.

[0045] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention.
