Technical Field

[0001] The utility model relates to the technical field of photovoltaic equipment, and more specifically, to a photovoltaic equipment. Background Art

[0002] Photovoltaic panels convert solar energy into light energy. To minimize power generation and improve ease of transport, multiple panels often need to be electrically connected and folded together.

DETAILED DESCRIPTION

[0038] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be understood as limiting the present invention.

[0039] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0040] The disclosure below provides many different embodiments or examples for realizing different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numbers and / or reference letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides examples of various specific processes and materials, but a person of ordinary skill in the art may be aware of the application of other processes and / or the use of other materials.

[0041] See also Figure 1-Figure 3 The photovoltaic device 1000 according to the embodiment of the present application includes a photovoltaic device 100 and an adapter 200. The number of photovoltaic devices 100 is multiple, for example, the number of photovoltaic devices 100 can be 2, 4, 5, 6, or 8. Multiple photovoltaic devices 100 can be rotatably connected via the adapter 200, or in other words, the adapter 200 can connect two adjacent photovoltaic devices 100. The photovoltaic device 100 is generally plate-shaped, having a long edge and a short edge that is substantially perpendicular to the long edge.

[0042] In one embodiment, one side of each photovoltaic device 100 is rotatably connected to one side of another photovoltaic device 100, and the other side of each photovoltaic device 100 is used to abut against a supporting surface. In other words, multiple photovoltaic devices 100 can be detachably connected end to end. For example, multiple photovoltaic devices 100 can be detachably connected end to end along the width direction of the photovoltaic device 100. In other words, the long edges of multiple photovoltaic devices 100 can be detachably connected via the adapter 200, thereby facilitating the assembly and disassembly of the photovoltaic device 1000 and facilitating its use.

[0043] Since the plurality of photovoltaic devices 1000 are connected by rotation, the photovoltaic device 1000 can be in a folded state and an unfolded state. When the photovoltaic device 1000 is in the folded state, the plurality of photovoltaic devices 100 are stacked, such as Figure 3 When the photovoltaic device 1000 is in the unfolded state, a predetermined angle α is formed between two adjacent photovoltaic devices 1000, as shown in FIG. Figure 2 As shown. For example, when the photovoltaic device 1000 is in the unfolded state, the adapter 200 maintains a predetermined angle between two adjacent photovoltaic devices 100. This facilitates storage and transportation of the folded photovoltaic device 1000. When the photovoltaic device 1000 is in the unfolded state, the adapter 200 limits the angle between the two adjacent photovoltaic devices 100 to a predetermined angle, maintaining the stability of the photovoltaic device 1000 and increasing the illuminated area of ​​the photovoltaic devices 100, thereby facilitating the conversion of solar energy into electrical energy.

[0044] In one example, the predetermined angle α is, for example, 120°-150°. For example, the predetermined angle α can be 120°, 125°, 130°, 140°, or 150°. In this way, the photovoltaic device 100 has a larger deployment area, which is beneficial for the photovoltaic device 1000 to convert solar energy into electrical energy.

[0045] It can be understood that, in some other embodiments, the predetermined angle α is, for example, 50°-170°. For example, the predetermined angle α can be 50°, 60°, or 70°.

[0046] Adjacent photovoltaic devices 100 are arranged at an angle relative to the supporting surface. On the one hand, this can save the floor space of the photovoltaic equipment 1000 without reducing the power generation capacity. On the other hand, when there are obstructions such as leaves on the photovoltaic device 100, the leaves and other obstructions can slide off the surface of the photovoltaic device 100, thereby avoiding partial obstruction of the photovoltaic device 100 and resulting in a reduction in power generation capacity.

[0047] See also Figure 7-Figure 9 In some embodiments, the photovoltaic device 100 may include a photovoltaic panel 10, a frame 20, a junction box 30, a first barrel 40 and a second barrel 50, and the photovoltaic panel 10 is arranged on the frame 20, for example, the frame 20 wraps the edge of the photovoltaic panel 10, or the edge of the photovoltaic panel 10 is embedded in the frame 20.

[0048] The junction box 30 is disposed on the photovoltaic panel 10 and is electrically connected to the photovoltaic panel 10. Each photovoltaic panel 10 may have two junction boxes 30, each of which may include a first junction box 31 and a second junction box 32. The first junction box 31 and the second junction box 32 are both electrically connected to the photovoltaic panel 10. Two adjacent photovoltaic devices 100 are electrically connected via the first junction box 31 and the second junction box 32.

[0049] The first cylindrical portion 40 protrudes from the surface of the photovoltaic panel 10. For example, the first cylindrical portion 40 can be disposed on the frame 20, protruding from the frame 20 toward the light-receiving surface of the photovoltaic device 100. The first cylindrical portion 40 is used to form an accommodating space 110 for accommodating the junction box 30 between two photovoltaic devices 100 when the two photovoltaic devices 100 are stacked. This prevents the junction box 30 from interfering with other adjacent photovoltaic panels 10, facilitating the stacking of multiple photovoltaic devices 100 to form a single unit.

[0050] The second barrel 50 protrudes from the backlight surface of the photovoltaic panel 10. The second barrel 50 is used to limit the position of two adjacent photovoltaic devices 100, so that the photovoltaic panels 10 of the two adjacent photovoltaic devices 100 are separated from each other, reducing the risk of the two photovoltaic panels 10 scratching each other and reducing the life of the photovoltaic device 100.

[0051] See also Figure 7 and Figure 8 In one embodiment, the photovoltaic panel 10 may include a substrate 11, a cell 12 and a translucent cover 13, the cell 12 is arranged on the substrate 11, and the translucent cover 13 covers the cell 12. Specifically, the substrate 11 can be made of materials such as PET, CPC, fiberglass board, glass, etc. The substrate 11 can be a sheet of rectangular or rounded rectangular material. The cell 12 can be fixed to the substrate 11 by pasting. The cell 12 is used to convert light energy into solar energy. The number of cell 12 can be multiple, and the multiple cell 12 is arranged in an array. For example, the row arrangement direction of the cell 12 is the same as the length direction of the substrate 11. The column arrangement direction of the cell 12 is the same as the width direction of the substrate 11.

[0052] The transparent cover plate 13 can be made of materials such as PET, CPC, and glass, and can have the same shape and size as the substrate 11. The transparent cover plate 13 can be bonded to the substrate 11 or the battery cell 12 by bonding.

[0053] See also Figure 7-Figure 9 In some embodiments, the photovoltaic panel 10 further includes a positive electrode trace 14 and a negative electrode trace 15. The positive electrode trace 14 is arranged on the substrate 11 and electrically connected to the battery cell 12. The positive electrode trace 14 has a first positive terminal 141 and a second positive terminal 142; the negative electrode trace 15 is arranged on the substrate 11 and electrically connected to the battery cell 12. The negative electrode trace 15 has a first negative terminal 151 and a second negative terminal 152, wherein the first positive terminal 141 and the first negative terminal 151 are spaced apart and are used to cooperate with each other to be electrically connected to the first junction box 31, and the second positive terminal 142 and the second negative terminal 152 are spaced apart and are used to cooperate with each other to be electrically connected to the second junction box 32.

[0054] In this way, the photovoltaic panel 10 can be arranged in parallel with the first junction box 31 and the second junction box 32 through the positive electrode wiring 14 and the negative electrode wiring 15. This facilitates the electrical connection of the photovoltaic panel 10 with an external device through at least one of the first junction box 31 and the second junction box 32, and facilitates the use of the photovoltaic panel 10. For example, two adjacent photovoltaic devices 100 are electrically connected through the first junction box 31 and the second junction box 32.

[0055] Specifically, the first junction box 31 is disposed on the photovoltaic panel 10 and is electrically connected to the first positive terminal 141 and the first negative terminal 151. The second junction box 32 is disposed on the photovoltaic panel 10 and is electrically connected to the second positive terminal 142 and the second negative terminal 152. Furthermore, the first junction box 31 and the second junction box 32 can both be disposed on the light-transmitting cover plate 13. Since the positive electrode trace 14 and the negative electrode trace 15 are both disposed on the substrate 11, the light-transmitting cover plate 13 can be provided with vias to allow the first positive terminal 141, the first negative terminal 151, the second positive terminal 142, and the second negative terminal 152 to pass from the substrate 11 to the surface of the light-transmitting cover plate 13, thereby connecting to the first junction box 31 and the second junction box 32.

[0056] See also Figure 9 In some embodiments, the positive electrode traces 14 surround multiple battery cells 12 and extend along the circumference of the substrate 11, while the negative electrode traces 15 surround multiple battery cells 12 and extend along the circumference of the substrate 11. In this way, the positive electrode traces 14 and the negative electrode traces 15 match the shape of the substrate 11, reducing the probability of interference between the positive electrode traces 14 and the negative electrode traces 15 and the battery cells 12. For example, the substrate 11 is a generally square plate, so the positive electrode traces 14 and the negative electrode traces 15 can be in the shape of a zigzag line.

[0057] See also Figure 7-Figure 9 In some embodiments, the first positive terminal 141 and the second positive terminal 142 are respectively located on both sides of the width of the substrate 11, and the first negative terminal 151 and the second negative terminal 152 are respectively located on both sides of the width of the substrate 11. In other words, the first positive terminal 141 and the second positive terminal 142 are respectively disposed near the two long edges of the substrate 11, and the first negative terminal 151 and the second negative terminal 152 are respectively disposed near the two short edges of the substrate 11. To this end, the first junction box 31 and the second junction box 32 are respectively disposed on both sides of the width direction of the photovoltaic panel 10, so that the photovoltaic device 100 is electrically connected to the external device from one side of the length edge of the photovoltaic panel 10, leaving more space for the first junction box 31 and the second junction box 32, which is conducive to the first junction box 31 and the second junction box 32 electrically connecting the two photovoltaic devices 100 together.

[0058] See also Figure 9 In some embodiments, the first positive terminal 141 and the second positive terminal 142 are staggered along the width direction of the substrate 11, and the first negative terminal 151 and the second negative terminal 152 are staggered along the width direction of the substrate 11. In other words, the first positive terminal 141 and the second positive terminal 142 are spaced apart along the length direction of the substrate 11, and the first negative terminal 151 and the second negative terminal 152 are spaced apart along the length direction of the substrate 11.

[0059] So, like Figure 4As shown, in two adjacent photovoltaic devices 100, the first junction box 31 of one photovoltaic device 100 is electrically connected to the second junction box 32 of the other photovoltaic device 100 via a cable 33. The first junction box 31 and the second junction box 32 can be spaced apart along the length of the photovoltaic panel 10, so that the bending angle of the cable 33 between the first junction box 31 on one photovoltaic device 100 and the second junction box 32 on the other photovoltaic device 100 is small, which facilitates the electrical connection of the two adjacent photovoltaic devices 100 through the first junction box 31 and the second junction box 32.

[0060] See also Figure 9 In some embodiments, the photovoltaic panel 10 further includes a positive electrode drain wire 16 and a negative electrode drain wire 17. The positive electrode drain wire 16 electrically connects the battery cell 12 and the positive electrode trace 14, and the negative electrode drain wire 17 electrically connects the battery cell 12 and the negative electrode trace 15. In this way, the positive electrode drain wire 16 can lead the current of the battery cell 12 to the positive electrode trace 14, and the negative electrode drain wire 17 can lead the current of the battery cell 12 to the negative electrode trace 15, so that the positive electrode trace 14 and the negative electrode trace 15 can lead the current to the outside of the photovoltaic panel 10.

[0061] See also Figure 9 In some embodiments, the positive electrode drain wire 16 and the negative electrode drain wire 17 are located on either side of the substrate 11 in the width direction. This allows for a wider range of arrangement for the positive electrode drain wire 16 and the negative electrode drain wire 17, reducing the probability of short circuits between the positive electrode drain wire 16 and the negative electrode drain wire 17. Specifically, the positive electrode drain wire 16 is located between the battery cell 12 and the positive electrode trace 14, and the negative electrode drain wire 17 is located between the battery cell 12 and the negative electrode trace 15.

[0062] See also Figure 9 In some embodiments, the positive electrode drain line 16 includes multiple positive electrode drain segments 161 spaced apart along the length of the substrate 11, and the negative electrode drain line 17 includes multiple negative electrode drain segments 171 spaced apart along the length of the substrate 11. The multiple positive electrode drain lines 16 and the multiple negative electrode drain lines 17 are connected in series through the battery cells 12, with one positive electrode drain line 16 connected to the positive electrode trace 14, and one negative electrode drain line 17 connected to the negative electrode trace 15. In this way, the multiple positive electrode drain lines 16 and the multiple negative electrode drain lines 17 can connect the battery cells 12 in series, which facilitates the extraction of the current generated by the battery cells 12.

[0063] In some embodiments, the width of the positive electrode trace 14 is greater than the width of the positive electrode drain line 16, and the width of the negative electrode trace 15 is greater than the width of the negative electrode drain line 17. Since the current amounts of the positive electrode trace 14 and the negative electrode trace 15 are relatively large, the width of the positive electrode trace 14 is greater than the width of the positive electrode drain line 16, and the width of the negative electrode trace 15 is greater than the width of the negative electrode drain line 17. This facilitates the photovoltaic panel 10 to draw current to external devices.

[0064] See also Figure 12-13 In some embodiments, the frame 20 is configured to rest against a supporting surface, thereby allowing the photovoltaic device 100 to rest against the supporting surface. The supporting surface may be, for example, the ground. The frame 20 may include a plurality of enclosure members 21 and a plurality of connectors 22. The enclosure members 21 and connectors 22 are connected end to end to form a ring. The connectors 22 are removably connected to two adjacent enclosure members 21.

[0065] In this way, the enclosing piece 21 and the connecting piece 22 of the frame 20 are detachably connected by plugging, making the frame 20 easy to assemble and easier to wrap the edge of the photovoltaic panel 10, thereby making the photovoltaic panel 10 and the frame 20 easy to assemble and disassemble.

[0066] Specifically, the enclosing piece 21 and the connecting piece 22 can be made of a relatively strong material such as aluminum alloy, thereby improving the impact resistance of the frame 20 and facilitating protection of the photovoltaic panel 10 .

[0067] In some embodiments, the enclosing member 21 is in the shape of a straight strip, and the connecting member 22 forms the corner portion of the frame 20. Since using larger components to form the corner portion of the frame 20 is more difficult to manufacture, the frame 20 is made in the shape of a straight strip, and the connecting member 22 forms the corner portion of the frame 20, which can reduce the manufacturing difficulty of the frame 20.

[0068] See also Figure 12-13 In some embodiments, the enclosure member 21 includes a long member 211 and a short member 212. The long member 211 forms the long edge of the frame 20, and the short member 212 forms the short edge of the frame 20. The connector 22 connects adjacent long members 211 and short members 212. In this way, the connector 22 can connect the long members 211 and the short members 212 to form the frame 20. Specifically, there are two long members 211 and two short members 212, and four connectors 22. The two long members 211 are arranged substantially parallel to each other, and the two short members 212 are arranged substantially parallel to each other.

[0069] See also Figure 14In some embodiments, a marker 23 is provided on the enclosure 21. Optionally, a marker 23 is provided on one of the short members 212. In this way, the marker 23 can enable multiple photovoltaic devices 100 to be assembled in a predetermined orientation, which is conducive to improving the assembly efficiency of multiple photovoltaic devices 100.

[0070] In some embodiments, the marker 23 comprises a coating applied to the surface of the enclosure 21, the coating having a different color than the short member 212. This allows the marker 23 to be distinguished from the enclosure 21, allowing for quicker identification of the orientation of the photovoltaic device 100 to be assembled. For example, the coating may be red, yellow, or other colors, while the enclosure 21 may be gray, black, or other colors. Of course, the marker 23 may also be a raised dot, a number, or other marking.

[0071] See also Figure 14 In some embodiments, the connector 22 includes a connecting portion 221 and an inserting portion 222 connected to the connecting portion 221. The enclosure 21 is provided with an inserting hole 210, and the inserting portion 222 is inserted into the inserting hole 210, so that the connecting portion 221 is connected to the enclosure 21. In this way, the insertion hole 210 and the inserting portion 222 cooperate to facilitate the connection between the connector 22 and the enclosure 21.

[0072] In some embodiments, the insertion holes 210 extend along the length of the enclosure 21. Alternatively, the insertion holes 210 may extend through both ends of the enclosure 21 along the length of the enclosure 21. In this way, the insertion holes 210 can reduce the weight of the enclosure 21, thereby reducing the weight of the frame 20, facilitating transportation of the photovoltaic device 100.

[0073] See also Figure 14 In some embodiments, the plug-in portion 222 is provided with a threaded hole 223, and the enclosure member 21 is provided with a through hole 213. The enclosure member 21 and the plug-in portion 222 are fixed together by threaded fasteners passing through the through hole 213 and screwing into the threaded hole 223. This provides a more stable connection between the enclosure member 21 and the connecting portion 221, reducing the risk of the frame 20 becoming loose.

[0074] See also Figure 14 In some embodiments, the frame 20 is provided with a mounting groove 24 spaced apart from the insertion hole 210. The notch of the mounting groove 24 faces away from the insertion hole 210. The mounting groove 24 extends along the frame 20 and passes through the enclosure 21 and the connecting portion 221. The mounting groove 24 is used to mount the photovoltaic panel 10. In this way, the edge of the photovoltaic panel 10 can be embedded in the mounting groove 24, making the connection between the frame 20 and the photovoltaic panel 10 more stable.

[0075] In one example, during the assembly process of the photovoltaic device 100, the enclosure 21 and the connector 22 can be sequentially clamped on the edge of the photovoltaic panel 10 through the installation groove 24, and then the enclosure 21 and the connector 22 are tightened with screws to stabilize the structure of the frame 20. Finally, glue is injected into the installation groove 24 so that the glue bonds the frame 20 to the photovoltaic panel 10, thereby improving the stability of the photovoltaic device 100.

[0076] See also Figure 2 and Figure 14 In some embodiments, the frame 20 is provided with a mounting hole 25 extending through the thickness of the photovoltaic panel 10. The mounting hole 25 is used to pass the latch 300 through so that the latch 300 is inserted under the support surface. In this manner, the mounting hole 25 can ensure stable installation of the photovoltaic device 100, maintaining a stable position of the photovoltaic device 100 and facilitating improved power generation efficiency of the photovoltaic device 100. Specifically, after the photovoltaic device 1000 is deployed, the latch 300 can be inserted through the mounting hole 25 and under the support surface, thereby maintaining a stable position of the photovoltaic device 1000.

[0077] In some embodiments, the mounting holes 25 are provided at the corners of the frame 20. Thus, the mounting holes 25 are located at the edge of the frame 20, which can improve the wind resistance of the photovoltaic device 100 and thus improve the stability after installation.

[0078] See also Figure 12 In some embodiments, each corner portion of the frame 20 is provided with a mounting hole 25. In this way, the structural consistency of the frame 20 is better, which is conducive to the production of the frame 20. Specifically, the mounting hole 25 passes through the connector 22, or in other words, the connector 22 is provided with a mounting hole 25 that passes through the connector 22 along the thickness direction of the photovoltaic panel 10. Exemplarily, the mounting hole 25 passes through the connecting portion 221. After the installation process of the photovoltaic device 100, the first photovoltaic device 100 and the last photovoltaic device 100 pass through the mounting hole 25 through the pin 300 so that the pin 300 is inserted under the bearing surface. It should be pointed out that in the first photovoltaic device 100 and the last photovoltaic device 100, the mounting hole 25 away from the bearing surface is not inserted with the pin 300.

[0079] As mentioned above, on the same photovoltaic device 100, the junction box 30 may include a first junction box 31 and a second junction box 32. Figure 6 and Figure 7In one embodiment, the first junction box 31 is connected to a cable 33, and the second junction box 32 is provided with a plug port 321. The connector at one end of the cable 33 is adapted to be plugged into the plug port 321. In other words, one end of the cable 33 is fixed to the first junction box 31, and the second junction box 32 is provided with the plug port 321. In two adjacent photovoltaic devices 100, the connector at the other end of the cable 33 on one photovoltaic device 100 is plugged into the plug port 321 of the second junction box 32 of the other photovoltaic device 100. Therefore, in the two adjacent photovoltaic devices 100, the first junction box 31 of one photovoltaic device 100 is electrically connected to the second junction box 32 of the other photovoltaic device 100 via the cable 33, which facilitates the electrical connection between the two photovoltaic devices 100.

[0080] Specifically, see Figure 10-11 In one embodiment, the second junction box 32 includes a box body 321, a box cover 322 and a wiring socket 323. The interior of the box body 321 is provided with a storage space 3211, and the end of the box body 321 is provided with a plug interface 3212 connected to the storage space 3211. The top of the box body 321 is provided with an opening 3213 spaced apart from the plug interface 3212 and connected to the storage space 3211. The box cover 322 covers the opening 3213. The wiring socket 323 is arranged in the storage space 3211 and is partially located between the opening 3213 and the plug interface 3212. In two adjacent photovoltaic devices 100, the connector of the other end of the cable on one photovoltaic device 100 is inserted into the plug interface 3212 of the second junction box 32 of the other photovoltaic device 100 and plugged into the wiring socket 323.

[0081] In this way, the top of the box body 321 is provided with an opening 3213 which is spaced apart from the plug interface 3212 and connected to the storage space 3211. The terminal block 323 is arranged in the storage space 3211 and is partially located between the opening 3213 and the plug interface 3212. This not only makes it easy to install the terminal block 323 in the storage space 3211, but also allows the peripheral surface of the storage space 3211 close to the plug interface 3212 to be a closed loop surface, which is beneficial to improving the waterproof performance of the connection between the terminal block 323 and the cable.

[0082] See also Figure 10-11 In some embodiments, the inner wall of the storage space 3211 is provided with limiting ribs 3214, and the terminal block 323 is provided with limiting grooves 3231. The limiting ribs 3214 engage in the limiting grooves 3231 to restrict the movement of the terminal block 323 along the normal direction of the insertion port 3212. In this way, the connector of the cable 33 and the terminal block 323 can be easily plugged together, improving the stability of the connection between the connector and the terminal block 323. The normal direction of the insertion port 3212 is the plugging direction of the cable connector.

[0083] In some embodiments, when multiple photovoltaic devices 100 are disassembled, the connector of the cable 33 can be plugged into an external device. In other words, when a single photovoltaic device 100 is used alone, the photovoltaic device 100 can output power through the cable 33, thereby facilitating the use of the single photovoltaic device 100.

[0084] See also Figure 6 and Figure 7 In some embodiments, the first barrel portion 40 is disposed on one side of the translucent cover plate 13. Since the junction box 30 is disposed on the translucent cover plate 13, disposing the first barrel portion 40 on one side of the translucent cover plate 13 allows, when two photovoltaic devices 100 are stacked, the first barrel portion 40 to form an accommodating space 110 between the two photovoltaic devices 100 for accommodating the first junction box 31, the second junction box 32, and other junction boxes 30. The first barrel portions 40 of two adjacent photovoltaic devices 100 abut against each other.

[0085] Specifically, the first barrel portion 40 can be disposed on the frame 20, making it easier to install. Furthermore, the first barrel portion 40 is disposed at a corner of the frame 20. As mentioned above, the connector 22 is formed at a corner of the frame 20, and therefore, the first barrel portion 40 can be disposed on the connector 22. For example, the first barrel portion 40 can be integrally formed with the connector 22.

[0086] In some embodiments, there are multiple first barrels 40, and the multiple first barrels 40 are spaced apart along the circumference of the photovoltaic panel 10. In this way, the multiple first barrels 40 can provide multiple points of support for two adjacent photovoltaic devices 100, which helps to maintain the stability of the shape of the accommodation space 110 formed between the two adjacent photovoltaic devices 100, thereby reducing interference with the first junction box 31 and the second junction box 32.

[0087] Specifically, in some embodiments, a first cylindrical portion 40 extends from one side of the connecting portion 221 , and the first cylindrical portion 40 is communicated with the mounting hole 25 .

[0088] See also Figure 6 and Figure 7 In some embodiments, the first barrel portion 40 is a magnetic member. Thus, two adjacent photovoltaic devices 100 can be attracted together by the first barrel portion 40 , which helps to keep the position of the photovoltaic device 100 stable.

[0089] See also Figure 6-Figure 8In some embodiments, the second barrel portion 50 is disposed on one side of the substrate 11, and the second barrel portion 50 is aligned with the first barrel portion 40 along the thickness direction of the photovoltaic panel 10. For example, the first barrel portion 40 and the second barrel portion 50 are respectively disposed on both sides of the frame 20 along the thickness direction of the photovoltaic panel 10. The second barrel portion 50 can provide support for two adjacent photovoltaic devices 100, so that when the photovoltaic device 1000 is in the folded state, the state of the two adjacent photovoltaic devices 100 is more stable.

[0090] like Figure 14 As shown, in some embodiments, the second barrel 50 is disposed on the frame 20, more specifically, the second barrel 50 can be disposed on the connector 22. The second barrel 50 can also be a magnetic member, so that two adjacent photovoltaic devices 100 can be attracted together by the second barrel 50, which helps to keep the position of the photovoltaic devices 100 stable.

[0091] Specifically, in some embodiments, a second cylindrical portion 50 extends from the other side of the connecting portion 221 , and the second cylindrical portion 50 is communicated with the mounting hole 25 .

[0092] like Figure 14 As shown, in some embodiments, the mounting hole 25 passes through the first barrel portion 40 and the second barrel portion 50. This makes the first barrel portion 40, the second barrel portion 50 and the mounting hole 25 fit more compactly.

[0093] See also Figure 15 In some embodiments, the adapter 200 connects to the frame 20 of two adjacent photovoltaic devices 100 to enable the two adjacent photovoltaic devices 100 to be rotatably connected. In this way, the frame 20 provides a mounting position for the adapter 200, allowing the two adjacent photovoltaic devices 100 to be rotatably connected via the adapter 200.

[0094] In one example, as discussed above, the long member 211 forms the long edge of the frame 20, the short member 212 forms the short edge of the frame 20, and the connector 22 connects adjacent long members 211 and short members 212. Therefore, the frame 20 includes two long edges and two short edges, the two long edges are arranged opposite to each other, and the two short edges are located between the two long edges. The adapter 200 can be connected to the long edge of the frame 20, or in other words, the adapter 200 can be connected to the long member 211 of the frame 20, so that the center of gravity of the photovoltaic device 1000 is lower when in the folded state, and transportation is more convenient.

[0095] See also Figure 15For the convenience of description, the two adjacent photovoltaic devices 100 are respectively a first photovoltaic device 101 and a second photovoltaic device 102. In some embodiments, the adapter 200 includes a first rotating member 201, a second rotating member 202 and a first damping member 206. The first damping member 206 connects the first rotating member 201 and the second rotating member 202 and forms a damping for the rotation between the first rotating member 201 and the second rotating member 202. The first rotating member 201 is fixed on the first photovoltaic device 101, and the second rotating member 202 is fixed on the second photovoltaic device 102. Specifically, the first rotating member 201 is fixed on the frame 20 of the first photovoltaic device 101, and the second rotating member 202 is fixed on the frame 20 of the second photovoltaic device 102.

[0096] In other words, the first rotating member 201 is fixed to the frame 20 of one of the two adjacent photovoltaic devices 100, and the second rotating member 202 is fixed to the frame 20 of the other photovoltaic device 100. In this way, the first rotating member 201 and the second rotating member 202 can rotatably connect the first photovoltaic device 101 and the second photovoltaic device 102.

[0097] In some embodiments, when the photovoltaic apparatus 1000 is in the deployed state, two adjacent photovoltaic devices 100 are maintained at a predetermined angle by the first damping member 206 .

[0098] In this way, the adapter 200 adjusts the rotational damping between the first rotating member 201 and the second rotating member 202 via the first damping member 206. When the photovoltaic device 1000 needs to be unfolded or folded, the damping value is adjusted to a smaller value, while when the photovoltaic device 1000 needs to maintain a predetermined angle, the damping value is adjusted to a larger value. This allows for infinite adjustment of the folding angle of two adjacent photovoltaic devices 100 in the photovoltaic device 1000, and makes the rotation of the adapter 200 smoother, improving the convenience of opening and closing the photovoltaic device 1000. Furthermore, by adjusting the rotational damping between the first rotating member 201 and the second rotating member 202 via the first damping member 206 to a reasonable value, it can prevent the photovoltaic devices 1000 from rotating too quickly and causing a pinching of the hand during the folding process of the photovoltaic device 1000.

[0099] In addition, the photovoltaic device 1000 is convenient to store and transport when folded. When the photovoltaic device 1000 is in the unfolded state, the angle between two adjacent photovoltaic devices 100 is limited to a predetermined angle by the adapter 200, so that the state of the photovoltaic device 1000 remains stable and the illuminated area of ​​the photovoltaic device 100 is increased, which is beneficial for the photovoltaic device 1000 to convert solar energy into electrical energy.

[0100] In some embodiments, when the photovoltaic device 1000 is in the unfolded state, the frame 20 of the first photovoltaic device 101 and the frame 20 of the second photovoltaic device 102 abut against each other, so that a predetermined angle α is formed between the first photovoltaic device 101 and the second photovoltaic device 102 .

[0101] In this way, the first photovoltaic device 101 and the second photovoltaic device 102 can use their own frame 20 to limit to form a predetermined angle α, which can make the structure of the adapter 200 simple and can make the unfolded state of the first photovoltaic device 101 and the second photovoltaic device 102 stable, which is beneficial for the photovoltaic equipment 1000 to convert solar energy into light energy.

[0102] In some embodiments, to facilitate the use of the photovoltaic device 1000, the first rotating member 201 and the second rotating member 202 are rotatably and detachably connected, so that the photovoltaic device 100 can be disassembled, which is beneficial for the separate use or transportation of the photovoltaic device 100.

[0103] See also Figures 15-18 In some embodiments, the first rotating member 201 has a first adapter hole 2011, and the second rotating member 202 has a second adapter hole 2021 coaxially disposed with the first adapter hole 2011. The first damping member 206 is sandwiched between the first rotating member 201 and the second rotating member 202 and has a through-hole 2061 coaxially disposed with the second adapter hole 2021. The adapter 200 further includes a locking member 207 that passes through the through-hole 2061 and is movably inserted into the first adapter hole 2011 and the second adapter hole 2021. The first damping member 206 forms pressure contact with the first rotating member 201 and the second rotating member 202 to damp the rotation between the first rotating member 201 and the second rotating member 202. In this manner, the first adapter hole 2011 and the second adapter hole 2021 facilitate the installation of the locking member 207, thereby rotatably connecting the first rotating member 201 and the second rotating member 202.

[0104] Specifically, the first rotating member 201 and the second rotating member 202 are rotatably connected via a locking member 207. The first damping member 206 may be a circular thin sheet having a through-hole 2061 formed at its center. The through-hole 2061 may be aligned with the first adapter hole 2011 and the second adapter hole 2021 along the direction in which the locking member 207 is inserted into the first adapter hole 2011. The locking member 207 may drive the second rotating member 202 to rotate relative to the first rotating member 201. During the rotation of the second rotating member 202 relative to the first rotating member 201, the greater the pressure between the first damping member 206 and the first rotating member 201 and the second rotating member 202, the greater the rotational damping between the first rotating member 201 and the second rotating member 202. Similarly, the smaller the pressure between the first damping member 206 and the first rotating member 201 and the second rotating member 202, the smaller the rotational damping between the first rotating member 201 and the second rotating member 202.

[0105] When the rotational damping between the first rotating member 201 and the second rotating member 202 is large enough, the first rotating member 201 and the second rotating member 202 can be kept difficult to rotate relative to each other, that is, the two adjacent photovoltaic devices 1000 connected to the first rotating member 201 and the second rotating member 202 can be kept at a predetermined angle.

[0106] Optionally, the first damping member 206 is made of plastic.

[0107] See also Figures 15-18 In some embodiments, the locking member 207 includes a first locking section 2071, a second locking section 2072, and an end portion 2073. The first locking section 2071 extends into the first adapter hole 2011 and is threaded. The second locking section 2072 extends into the second adapter hole 2021. The end portion 2073 has a larger radial dimension than the second locking section 2072 and is exposed outside the second adapter hole 2021. Thus, by adjusting the threaded advance of the first locking section 2071, the friction between the first damping member 206 and the first and second rotating members 201, 202 is controlled, thereby adjusting the rotational damping between the first and second rotating members 201, 202.

[0108] Specifically, the more the locking member 207 is screwed into the first locking section 2071, the tighter the contact between the first rotating member 201, the first damping member 206, and the first rotating member 201, and the greater the friction between the first damping member 206 and the first rotating member 201 and the second rotating member 202. This increases the rotational damping between the first rotating member 201 and the second rotating member 202, and accordingly increases the rotational force required to open and close the first photovoltaic device 101 and the second photovoltaic device 102. Conversely, by properly unscrewing the first locking section 2071 out of the first adapter hole 2011, the friction between the first damping member 206 and the first rotating member 201 and the second rotating member 202 decreases, thereby reducing the rotational damping between the first rotating member 201 and the second rotating member 202 and correspondingly reducing the rotational force required to open and close the first photovoltaic device 101 and the second photovoltaic device 102.

[0109] When the photovoltaic device 1000 is in the unfolded or stored state, the screw-in amount of the first locking section 2071 can be adjusted until the rotational damping between the first rotating member 201 and the second rotating member 202 increases to a maximum value, making it difficult for the first rotating member 201 and the second rotating member 202 to rotate relative to each other, thereby maintaining the angle between the two adjacent photovoltaic devices 100 when the first locking section 2071 is screwed in to the maximum value.

[0110] See also Figures 15-18 In some embodiments, the adapter 200 further includes a second damping member 208, which is interposed between the second rotating member 202 and the end portion 2073 of the locking member 207. Thus, the second damping member 208 can provide rotational damping between the end portion 2073 of the locking member 207 and the second rotating member 202, thereby facilitating the locking member 207 to cooperate with the first damping member 206 to adjust the friction between the first rotating member 201 and the second rotating member 202.

[0111] Specifically, the second damping member 208 can be a circular ring structure, and the locking member 207 sequentially passes through the second damping member 208, the second adapter hole 2021 of the second rotating member 202, and the through hole 2061 of the first damping member 206, and extends into the first adapter hole 2011 of the first rotating member 201. Adjusting the screwing amount of the locking member 207 can control the friction between the second damping member 208 and the end 2073 of the locking member 207 and the second rotating member 202, thereby adjusting the rotational force required for the relative rotation of the first rotating member 201 and the second rotating member 202.

[0112] See also Figures 15-18In some embodiments, the first adapter hole 2011 passes through the first rotating member 201, and the number of the second rotating member 202, the first damping member 206 and the locking member 207 are all two. A group of first damping members 206, second rotating members 202 and locking members 207 are respectively provided at both ends of the first rotating member 201 along the direction in which the first adapter hole 2011 passes through.

[0113] In this way, the two groups of first damping members 206, second rotating members 202 and locking members 207 are respectively arranged in sequence at both ends of the first rotating member 201 along the penetrating direction of the first adapter hole 2011, which is conducive to the relative rotation of the first rotating member 201 and the second rotating member 202, and drives the two adjacent photovoltaic devices 100 to maintain stable rotation when opening and closing.

[0114] Specifically, the two locking members 207 are respectively inserted into the two second rotating members 202 at both ends of the first rotating member 201, and respectively pass through the two first damping members 206 and are inserted into the first adapter hole 2011. The two second rotating members 202 at both ends of the first rotating member 201 are fixedly connected to the second photovoltaic device 102.

[0115] Optionally, a second damping member 208 is sandwiched between the end portions 2073 of the two locking members 207 located at both ends of the first rotating member 201 and the two second rotating members 202 .

[0116] See also Figures 15-18 In some embodiments, when the photovoltaic device 1000 is in the deployed state, the first rotating member 201 abuts the frame 20 of the second photovoltaic device 102, and the second rotating member 202 abuts the frame 20 of the first photovoltaic device 101, thereby forming a predetermined angle α between the first photovoltaic device 101 and the second photovoltaic device 102. In this manner, the first rotating member 201 and the second rotating member 202 can limit the angle between the first photovoltaic device 101 and the second photovoltaic device 102, thereby facilitating stable operation of the first photovoltaic device 101 and the second photovoltaic device 102.

[0117] See also Figures 15-18 In some embodiments, the first rotating member 201 includes a first adapter portion 2013, a first mounting portion 2014, and a first abutting portion 2015. The first mounting portion 2014 and the first abutting portion 2015 are both connected to the first adapter portion 2013. The first mounting portion 2014 is fixedly connected to the frame 20 of the first photovoltaic device 101. The first adapter portion 2013 is provided with a first adapter hole 2011. The first abutting portion 2015 abuts against the frame 20 of the second photovoltaic device 102 when the first photovoltaic device 101 and the second photovoltaic device 102 are unfolded.

[0118] The second rotating member 202 includes a second adapter portion 2023, a second mounting portion 2024, and a second abutting portion 2025. The second mounting portion 2024 and the second abutting portion 2025 are both connected to the second adapter portion 2023. The second mounting portion 2024 is fixedly connected to the frame 20 of the second photovoltaic device 102. The second adapter portion 2023 is provided with a second adapter hole 2021. The second abutting portion 2025 abuts the frame 20 of the first photovoltaic device 101 when the first photovoltaic device 101 and the second photovoltaic device 102 are unfolded. In this way, the first abutting portion 2015 and the second abutting portion 2025 can achieve angular positioning between the first photovoltaic device 101 and the second photovoltaic device 102, and the first mounting portion 2014 and the second mounting portion 2024 can ensure that the first rotating member 201 and the second rotating member 202 are stably connected to the corresponding frame 20.

[0119] Specifically, the first mounting portion 2014 and the second mounting portion 2024 may be in a sheet shape, and the first mounting portion 2014 and the second mounting portion 2024 may be fixedly connected to the corresponding frame 20 by fasteners such as screws.

[0120] In some embodiments, the first rotating member 201 and the second rotating member 202 are connected to the long edges of the corresponding frame 20. This allows the photovoltaic device 1000 to have a lower center of gravity when folded, making transportation more convenient. For example, the first mounting portion 2014 of the first rotating member 201 is fixedly connected to the long member 211 of the frame 20 of the first photovoltaic device 101, and the second mounting portion 2024 of the second rotating member 202 is fixedly connected to the long member 211 of the frame 20 of the second photovoltaic device 102.

[0121] In one embodiment, the photovoltaic device 100 includes a photovoltaic panel 10, a junction box 30 and a first barrel 40, wherein the photovoltaic panel 10 includes a substrate 11, a cell 12 and a light-transmitting cover 13, wherein the cell 12 is arranged on the substrate 11, and the light-transmitting cover 13 covers the cell 12; the junction box 30 is arranged on the light-transmitting cover 13; the first barrel 40 is arranged on one side of the light-transmitting cover 13, and the first barrel 40 is used to form a storage space for accommodating the junction box 30 between the two photovoltaic devices 100 when the two photovoltaic devices 100 are stacked.

[0122] In this way, the junction box 30 is arranged on the transparent cover 13, so that the photovoltaic device 100 is convenient to use during use, and there is no need to connect wires from the backlight side of the photovoltaic device 100. In addition, the first barrel 40 forms a storage space for accommodating the junction box 30 between the two photovoltaic devices 100, which can reduce the interference between the junction box 30 and other photovoltaic devices 100 and improve the service life of the photovoltaic device 100.

[0123] In summary, in some embodiments, a photovoltaic device 1000 includes a plurality of photovoltaic devices 100 and an adapter 200. Each photovoltaic device 100 includes a photovoltaic panel 10 and a frame 20, with the frame 20 wrapping around the edge of the photovoltaic panel 10. The adapter 200 connects two adjacent photovoltaic devices 100. The adapter 200 includes a first rotating member 201, a second rotating member 202 rotatably connected to the first rotating member 201, and a first damping member 206. The first rotating member 201 is fixed to the frame 20 of one of the two adjacent photovoltaic devices 100, and the second rotating member 202 is fixed to the frame 20 of the other photovoltaic device 100. The photovoltaic device 1000 can be in a folded state and an unfolded state. When the photovoltaic device 1000 is in the unfolded state, the first damping member 206 maintains a predetermined angle between the two adjacent photovoltaic devices 100. In this way, the adapter 200 adjusts the rotational damping value between the first rotating member 201 and the second rotating member 202 through the first damping member 206. The damping value is adjusted to be smaller when the photovoltaic device 1000 needs to be unfolded or folded, and the damping value is adjusted to be larger when the photovoltaic device 1000 needs to maintain a predetermined angle, thereby realizing stepless adjustment of the folding angle of two adjacent photovoltaic devices 100 in the photovoltaic device 1000, and making the rotation of the adapter 200 more stable, thereby improving the convenience of opening and closing the photovoltaic device 1000.
