[0001] This utility model relates to the field of photovoltaic equipment technology, and more specifically, to a photovoltaic device. Background Technology
[0002] Photovoltaic panels are devices that convert solar energy into light energy. To increase power generation and facilitate transport, multiple photovoltaic panels are often electrically connected. How to make photovoltaic panels more convenient to use has become a technical problem to be solved. Utility Model Content
[0003] This utility model provides a photovoltaic device.
[0004] A photovoltaic (PV) device includes multiple PV units and an adapter. Each PV unit includes a PV panel and a frame, with the frame covering the edge of the PV panel. The adapter connects two adjacent PV units and includes a first rotating member and a second rotating member rotatably connected to the first rotating member. The first rotating member is fixed to the frame of one of the two adjacent PV units, and the second rotating member is fixed to the frame of the other PV unit. The PV device can be in a folded state and an unfolded state. When the PV device is in the unfolded state, the two adjacent PV units are maintained at a predetermined angle by the adapter. Thus, when the PV device is in the unfolded state, the angle between the two adjacent PV units is limited to a predetermined angle by the adapter, making the state of the PV device stable, increasing the light-receiving area of the PV device, and facilitating the conversion of solar energy into electrical energy.
[0005] In some embodiments, the first rotating member is provided with a first adapter hole, the second rotating member is provided with a second adapter hole coaxially arranged with the first adapter hole, and the adapter member further includes a rotating shaft, which is movably inserted into the first adapter hole and the second adapter hole.

The first abutting part abuts against the frame of the second photovoltaic device when the first photovoltaic device and the second photovoltaic device are unfolded.
[0010] The second rotating component includes a second adapter, a second mounting portion, and a second abutment portion. Both the second mounting portion and the second abutment portion are connected to the second adapter. The second mounting portion is fixedly connected to the frame of the second photovoltaic device. The second adapter portion is provided with a second adapter hole. The second abutment portion abuts against the frame of the first photovoltaic device when the first photovoltaic device and the second photovoltaic device are unfolded.

When the photovoltaic device is in a folded state, the first cylindrical portions of two adjacent photovoltaic devices abut against each other to form a receiving space between the two photovoltaic devices for accommodating the first junction box and the second junction box.
[0014] In some embodiments, the photovoltaic device further includes a second cylindrical portion disposed on one side of the substrate, the second cylindrical portion being aligned with the first cylindrical portion along the thickness direction of the photovoltaic panel.

To simplify the disclosure, specific examples of components and settings are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or settings discussed. In addition, examples of various specific processes and materials are provided in this invention, but those skilled in the art will recognize the application of other processes and / or the use of other materials.
[0040] Please see Figures 1-3 The photovoltaic device 1000 of this application includes a photovoltaic device 100 and an adapter 200. The number of photovoltaic devices 100 can be multiple, for example, 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, and has a long edge and a short edge substantially perpendicular to the long edge.
[0041] 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 bearing surface. Alternatively, 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, that is, the long edges of multiple photovoltaic devices 100 can be detachably connected through adapters 200, thereby facilitating the assembly and disassembly of the photovoltaic device 1000 and making the photovoltaic device 1000 easier to use.
[0042] Because multiple photovoltaic devices 1000 are rotatably connected, the photovoltaic devices 1000 can be in a folded state and an unfolded state. When the photovoltaic devices 1000 are in the folded state, the multiple photovoltaic devices 100 are stacked, such as... Figure 3 As shown. When the photovoltaic device 1000 is in the deployed state, a predetermined angle α is formed between two adjacent photovoltaic devices 100, as shown. Figure 2 As shown. Exemplarily, when the photovoltaic device 1000 is in the unfolded state, two adjacent photovoltaic devices 100 are maintained at a predetermined angle by the adapter 200. Thus, the photovoltaic device 1000 is convenient to store and transport when folded, and when unfolded, the angle between two adjacent photovoltaic devices 100 is limited to a predetermined angle by the adapter 200, keeping the photovoltaic device 1000 stable and increasing the light-receiving area of the photovoltaic device 100, which is beneficial for the photovoltaic device 1000 to convert solar energy into electrical energy.
[0043] In one example, the predetermined angle α is, for example, 120°-150°, such as 120°, 125°, 130°, 140°, or 150°. This results in a larger unfolded area for the photovoltaic device 1000, which is beneficial for the photovoltaic device 1000 to convert solar energy into electrical energy.
[0044] It is understood that in some other embodiments, the predetermined angle α is, for example, 50°-170°, such as 50°, 60° or 70°.
[0045] The adjacent photovoltaic devices 100 are set at an angle relative to the bearing surface. Without reducing the power generation, the photovoltaic devices 1000 can save space. On the other hand, when there are obstructions such as leaves on the photovoltaic devices 100, the leaves and other obstructions can slide off the surface of the photovoltaic devices 100, avoiding partial shading of the photovoltaic devices 100 and thus reducing the power generation.
[0046] Please see Figures 7-9In some embodiments, the photovoltaic device 100 may include a photovoltaic panel 10, a frame 20, a junction box 30, a first cylindrical portion 40 and a second cylindrical portion 50. The photovoltaic panel 10 is disposed on the frame 20. For example, the frame 20 covers the edge of the photovoltaic panel 10, or the edge of the photovoltaic panel 10 is embedded in the frame 20.
[0047] A junction box 30 is installed on the photovoltaic panel 10 and is electrically connected to the photovoltaic panel 10. Each photovoltaic panel 10 can have two junction boxes 30, which may include a first junction box 31 and a second junction box 32, both of which are electrically connected to the photovoltaic panel 10. Two adjacent photovoltaic devices 100 are electrically connected through the first junction box 31 and the second junction box 32.
[0048] 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 a receiving space 110 between the two photovoltaic devices 100 when they are stacked, thereby making the junction box 30 less likely to interfere with other adjacent photovoltaic panels 10, which is beneficial for multiple photovoltaic devices 100 to be stacked into a whole.
[0049] The second cylindrical portion 50 protrudes from the back surface of the photovoltaic panel 10. The second cylindrical portion 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 scraping each other and reducing the lifespan of the photovoltaic device 100.
[0050] Please see Figure 7 and Figure 8 In one embodiment, the photovoltaic panel 10 may include a substrate 11, solar cells 12, and a light-transmitting cover plate 13. The solar cells 12 are disposed on the substrate 11, and the light-transmitting cover plate 13 covers the solar cells 12. Specifically, the substrate 11 may be made of materials such as PET, CPC, fiberglass board, or glass. The substrate 11 may be a rectangular or rounded rectangular sheet. The solar cells 12 may be fixed to the substrate 11 by adhesive bonding. The solar cells 12 are used to convert light energy into solar energy, and there may be multiple solar cells 12 arranged in an array. For example, the row arrangement direction of the solar cells 12 is the same as the length direction of the substrate 11, and the column arrangement direction of the solar cells 12 is the same as the width direction of the substrate 11.
[0051] The light-transmitting cover 13 can be made of materials such as PET, CPC, and glass, and the light-transmitting cover 13 can have the same shape and size as the substrate 11. The light-transmitting cover 13 can be bonded to the substrate 11 or the battery cell 12 by means of adhesive bonding.
[0052] Please see Figures 7-9 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 disposed on the substrate 11 and electrically connected to the solar 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 disposed on the substrate 11 and electrically connected to the solar cell 12. The negative electrode trace 15 has a first negative terminal 151 and a second negative terminal 152. The first positive terminal 141 and the first negative terminal 151 are spaced apart and used to cooperate with each other to be electrically connected to the first junction box 31. The second positive terminal 142 and the second negative terminal 152 are spaced apart and used to cooperate with each other to be electrically connected to the second junction box 32.
[0053] Thus, the photovoltaic panel 10, through the positive electrode wiring 14 and the negative electrode wiring 15, allows the first junction box 31 and the second junction box 32 to be connected in parallel. This facilitates the photovoltaic panel 10 to be electrically connected to external devices through at least one of the first junction box 31 and the second junction box 32, making the use of the photovoltaic panel 10 convenient. For example, two adjacent photovoltaic devices 100 can be electrically connected through the first junction box 31 and the second junction box 32.
[0054] Specifically, the first junction box 31 is disposed on the photovoltaic panel 10 and electrically connected to the first positive terminal 141 and the first negative terminal 151, and the second junction box 32 is disposed on the photovoltaic panel 10 and electrically connected to the second positive terminal 142 and the second negative terminal 152. Further, both the first junction box 31 and the second junction box 32 can 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 through holes so that the first positive terminal 141, the first negative terminal 151, the second positive terminal 142, and the second negative terminal 152 can extend from the substrate 11 to the surface of the light-transmitting cover plate 13, thereby connecting with the first junction box 31 and the second junction box 32.
[0055] Please see Figure 9 In some embodiments, the positive electrode trace 14 extends around the plurality of battery cells 12 and along the circumference of the substrate 11, and the negative electrode trace 15 extends around the plurality of battery cells 12 and along the circumference of the substrate 11. Thus, the positive electrode trace 14 and the negative electrode trace 15 conform to the shape of the substrate 11, reducing the probability of interference between the positive electrode trace 14 and the negative electrode trace 15 and the battery cells 12, respectively. For example, the substrate 11 is generally a square plate; therefore, the positive electrode trace 14 and the negative electrode trace 15 can be in a zigzag shape.
[0056] Please see Figures 7-9In some embodiments, the first positive terminal 141 and the second positive terminal 142 are located on both sides of the width of the substrate 11, and the first negative terminal 151 and the second negative terminal 152 are located on both sides of the width of the substrate 11. Alternatively, the first positive terminal 141 and the second positive terminal 142 are respectively located near the two long edges of the substrate 11, and the first negative terminal 151 and the second negative terminal 152 are respectively located near the two short edges of the substrate 11. Therefore, the first junction box 31 and the second junction box 32 are respectively located on both sides of the photovoltaic panel 10 in the width direction. This allows the photovoltaic device 100 to be electrically connected to external equipment from one side of the long edge of the photovoltaic panel 10, and provides more space for the first junction box 31 and the second junction box 32, which is beneficial for electrically connecting two photovoltaic devices 100 together.
[0057] Please see Figure 9 In some embodiments, the first positive terminal 141 and the second positive terminal 142 are offset along the width direction of the substrate 11, and the first negative terminal 151 and the second negative terminal 152 are offset along the width direction of the substrate 11. Alternatively, 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.
[0058] Thus, as Figure 4 As 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 of one photovoltaic device 100 and the second junction box 32 of the other photovoltaic device 100 is small. This facilitates the electrical connection between the two adjacent photovoltaic devices 100 via the first junction box 31 and the second junction box 32.
[0059] Please see Figure 9 In some embodiments, the photovoltaic panel 10 further includes a positive electrode lead-in wire 16 and a negative electrode lead-in wire 17. The positive electrode lead-in wire 16 is electrically connected to the solar cell 12 and the positive electrode trace 14, and the negative electrode lead-in wire 17 is electrically connected to the solar cell 12 and the negative electrode trace 15. In this way, the positive electrode lead-in wire 16 can lead the current from the solar cell 12 to the positive electrode trace 14, and the negative electrode lead-in wire 17 can lead the current from the solar 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.
[0060] Please see Figure 9In some embodiments, the positive electrode lead 16 and the negative electrode lead 17 are located on opposite sides of the substrate 11 in the width direction. This allows for a wider arrangement of the positive electrode lead 16 and the negative electrode lead 17, reducing the probability of short circuits. Specifically, the positive electrode lead 16 is located between the battery cell 12 and the positive electrode trace 14, and the negative electrode lead 17 is located between the battery cell 12 and the negative electrode trace 15.
[0061] Please see Figure 9 In some embodiments, the positive electrode lead line 16 includes multiple positive electrode lead segments 161 spaced apart along the length of the substrate 11, and the negative electrode lead line 17 includes multiple negative electrode lead segments 171 spaced apart along the length of the substrate 11. The multiple positive electrode lead lines 16 and multiple negative electrode lead lines 17 are connected in series through the battery cell 12, wherein one positive electrode lead line 16 is connected to the positive electrode trace 14, and one negative electrode lead line 17 is connected to the negative electrode trace 15. In this way, the multiple positive electrode lead lines 16 and multiple negative electrode lead lines 17 can connect the battery cell 12 in series, which is beneficial for drawing out the current generated by the battery cell 12.
[0062] In some embodiments, the width of the positive electrode trace 14 is greater than the width of the positive electrode lead-in trace 16, and the width of the negative electrode trace 15 is greater than the width of the negative electrode lead-in trace 17. Since the current carrying capacity of the positive electrode trace 14 and the negative electrode trace 15 is relatively large, the greater width of the positive electrode trace 14 compared to the positive electrode lead-in trace 16, and the greater width of the negative electrode trace 15 compared to the negative electrode lead-in trace 17, facilitates the photovoltaic panel 10 in drawing current to external devices.
[0063] Please see Figures 12-13 In some embodiments, the frame 20 is used to abut against a support surface, thereby allowing the photovoltaic device 100 to abut against the support surface. The support surface is, 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 being connected end to end to form a ring, and the connectors 22 being detachably inserted into two adjacent enclosure members 21.
[0064] Thus, the cladding member 21 and the connector 22 of the frame 20 are detachably connected by plugging, making the frame 20 easy to assemble and more easily wrap the edge of the photovoltaic panel 10, thereby making the photovoltaic panel 10 and the frame 20 easy to assemble and disassemble.
[0065] Specifically, the enclosure 21 and the connector 22 can be made of high-strength materials such as aluminum alloy, which can improve the impact resistance of the frame 20 and help protect the photovoltaic panel 10.
[0066] In some embodiments, the enclosure 21 is in the shape of a straight strip, and the connector 22 forms the corner portion of the frame 20. Since it is difficult to manufacture the corner portion of the frame 20 using large-sized components, the frame 20 is made in the shape of a straight strip, and the connector 22 forms the corner portion of the frame 20, which reduces the manufacturing difficulty of the frame 20.
[0067] Please see Figures 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. A connector 22 connects adjacent long members 211 and short members 212. Thus, 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 in approximately parallel positions, and the two short members 212 are arranged in approximately parallel positions.
[0068] Please see Figure 14 In some embodiments, the enclosure 21 is provided with an identifier 23. Optionally, one of the short components 212 is provided with an identifier 23. In this way, the identifier 23 can enable multiple photovoltaic devices 100 to be assembled in a predetermined orientation, which is beneficial to improving the assembly efficiency of multiple photovoltaic devices 100.
[0069] In some embodiments, the marker 23 includes a coating on the surface of the enclosure 21, the color of which differs from the color of the short member 212. This allows the marker 23 to be distinguished from the enclosure 21, enabling faster identification of the location where the photovoltaic device 100 needs to be assembled. For example, the coating color can be red, yellow, etc., and the enclosure 21 color can be gray, black, etc. Of course, the marker 23 can also be raised dots, numbers, or other markings.
[0070] Please see Figure 14 In some embodiments, the connector 22 includes a connecting portion 221 and a plug-in portion 222 connected to the connecting portion 221. The enclosure 21 is provided with a plug-in hole 210, and the plug-in portion 222 is inserted into the plug-in hole 210. The connecting portion 221 mates with the enclosure 21. In this way, the plug-in hole 210 and the plug-in portion 222 cooperate to make it easy for the connector 22 and the enclosure 21 to be plugged together.
[0071] In some embodiments, the insertion hole 210 extends along the length of the enclosure 21. Optionally, the insertion hole 210 may extend through both ends of the enclosure 21 along its length. In this way, the insertion hole 210 can reduce the weight of the enclosure 21, thereby reducing the weight of the frame 20, which is beneficial for the transportation of the photovoltaic device 100.
[0072] Please see 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 by threaded fasteners passing through the through hole 213 and screwing into the threaded hole 223. In this way, the enclosure member 21 and the connecting portion 221 are connected more stably, reducing the risk of the frame 20 becoming loose.
[0073] Please see Figure 14 In some embodiments, the frame 20 is provided with a mounting groove 24 spaced apart from the insertion hole 210. The opening 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.
[0074] In one example, during the assembly of the photovoltaic device 100, the enclosure 21 and the connector 22 can be sequentially secured to the edge of the photovoltaic panel 10 via the mounting groove 24. Then, the enclosure 21 and the connector 22 are tightened with screws to stabilize the structure of the frame 20. Finally, adhesive is injected into the mounting groove 24 to bond the frame 20 to the photovoltaic panel 10, thereby improving the stability of the photovoltaic device 100.
[0075] Please see Figure 2 and Figure 14 In some embodiments, the frame 20 is provided with mounting holes 25 extending through the frame 20 along the thickness direction of the photovoltaic panel 10. The mounting holes 25 allow a pin 300 to pass through and be inserted under the bearing surface. Thus, the mounting holes 25 ensure stable installation of the photovoltaic device 100, maintaining its position and improving its power generation efficiency. Specifically, after the photovoltaic device 1000 is unfolded, the pin 300 can pass through the mounting holes 25 and be inserted under the bearing surface, thereby stabilizing the position of the photovoltaic device 1000.
[0076] In some embodiments, the mounting holes 25 are located at the corners of the frame 20. Thus, the mounting holes 25 are located at the edges of the frame 20, which improves the wind resistance of the photovoltaic device 100 and consequently enhances its stability after installation.
[0077] Please see Figure 12In some embodiments, each corner of the frame 20 is provided with a mounting hole 25. This results in better structural consistency of the frame 20, which is beneficial for its manufacturing. Specifically, the mounting hole 25 penetrates the connector 22; in other words, the connector 22 is provided with a mounting hole 25 penetrating the connector 22 along the thickness direction of the photovoltaic panel 10. For example, the mounting hole 25 penetrates the connecting portion 221. After the photovoltaic device 100 is installed, the first photovoltaic device 100 and the last photovoltaic device 100 pass through the mounting hole 25 with a pin 300 so that the pin 300 is inserted under the bearing surface. It should be noted that in the first photovoltaic device 100 and the last photovoltaic device 100, the mounting hole 25 furthest from the bearing surface is not fitted with a pin 300.
[0078] 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. Please refer again. Figure 6 and Figure 7 In one embodiment, a first junction box 31 is connected to a cable 33, and a second junction box 32 is provided with a connector 321, wherein a connector at one end of the cable 33 is adapted to be inserted into the connector 321. Alternatively, one end of the cable 33 is fixed to the first junction box 31, and the second junction box 32 is provided with a connector 321. In two adjacent photovoltaic devices 100, the connector at the other end of the cable 33 on one photovoltaic device 100 is inserted into the connector 321 of the second junction box 32 of the other photovoltaic device 100. Therefore, 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 the cable 33, which facilitates the electrical connection between the two photovoltaic devices 100.
[0079] Specifically, please refer to Figures 10-11 In one embodiment, the second junction box 32 includes a box body 321, a box cover 322, and a terminal block 323. The box body 321 has a storage space 3211 inside. The end of the box body 321 has a plug interface 3212 communicating with the storage space 3211. The top of the box body 321 has an opening 3213 spaced apart from the plug interface 3212 and communicating with the storage space 3211. The box cover 322 covers the opening 3213. The terminal block 323 is located 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 connected to the terminal block 323.
[0080] Thus, the top of the housing 321 is provided with an opening 3213 that is spaced apart from the plug interface 3212 and communicates with the storage space 3211. The terminal block 323 is located 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 into the storage space 3211, but also makes the periphery of the storage space 3211 near the plug interface 3212 a closed loop surface, which is beneficial to improving the waterproof performance of the connector between the terminal block 323 and the cable.
[0081] Please see Figures 10-11 In some embodiments, the inner wall of the storage space 3211 is provided with a limiting rib 3214, and the terminal block 323 is provided with a limiting groove 3231. The limiting rib 3214 is engaged in the limiting groove 3231 to restrict the movement of the terminal block 323 along the normal direction of the plug-in interface 3212. In this way, the connector of the cable 33 can be readily plugged into the terminal block 323, improving the stability of the connection between the connector of the cable 33 and the terminal block 323. The normal direction of the plug-in interface 3212 is the insertion direction of the cable connector.
[0082] In some implementations, when multiple photovoltaic devices 100 are disassembled, the connector of the cable 33 can be plugged into an external device. That is, when a single photovoltaic device 100 is used alone, the photovoltaic device 100 can output electrical energy through the cable 33, thereby facilitating the use of a single photovoltaic device 100.
[0083] Please see Figure 6 and Figure 7 In some embodiments, the first cylindrical portion 40 is disposed on one side of the light-transmitting cover plate 13. Since the junction box 30 is disposed on the light-transmitting cover plate 13, disposing the first cylindrical portion 40 on one side of the light-transmitting cover plate 13 allows the first cylindrical portion 40 to create a receiving space 110 between the two photovoltaic devices 100 to accommodate the junction boxes 30, such as the first junction box 31 and the second junction box 32. The first cylindrical portions 40 of two adjacent photovoltaic devices 100 abut against each other.
[0084] Specifically, the first cylindrical portion 40 can be disposed on the frame 20, making it easier to install. Furthermore, the first cylindrical portion 40 can be disposed at a corner of the frame 20. As mentioned above, the connector 22 has a corner portion formed on the frame 20; therefore, the first cylindrical portion 40 can be disposed on the connector 22. For example, the first cylindrical portion 40 can be integrally formed with the connector 22.
[0085] In some embodiments, there are multiple first cylindrical sections 40, which are arranged at intervals along the circumference of the photovoltaic panel 10. In this way, the multiple first cylindrical sections 40 can provide multi-point support for two adjacent photovoltaic devices 100, which helps to maintain the stability of the shape of the accommodating 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.
[0086] Specifically, in some embodiments, a first cylindrical portion 40 extends from one side of the connecting portion 221, and the first cylindrical portion 40 communicates with the mounting hole 25.
[0087] Please see Figure 6 and Figure 7 In some embodiments, the first cylindrical portion 40 is a magnetic element, so that two adjacent photovoltaic devices 100 can be attracted together by the first cylindrical portion 40, which helps to keep the position of the photovoltaic devices 100 stable.
[0088] Please see Figures 6-8 In some embodiments, the second cylindrical portion 50 is disposed on one side of the substrate 11, and the second cylindrical portion 50 is aligned with the first cylindrical portion 40 along the thickness direction of the photovoltaic panel 10. For example, the first cylindrical portion 40 and the second cylindrical portion 50 are respectively disposed on both sides of the frame 20 along the thickness direction of the photovoltaic panel 10. The second cylindrical portion 50 can provide support for two adjacent photovoltaic devices 100, so that the state of the two adjacent photovoltaic devices 100 is more stable when the photovoltaic device 1000 is in a folded state.
[0089] like Figure 14 As shown, in some embodiments, the second cylindrical portion 50 is disposed on the frame 20, and more specifically, the second cylindrical portion 50 may be disposed on the connector 22. The second cylindrical portion 50 may also be a magnetic element, so that two adjacent photovoltaic devices 100 can be attracted together by the second cylindrical portion 50, which helps to keep the position of the photovoltaic devices 100 stable.
[0090] 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 communicates with the mounting hole 25.
[0091] like Figure 14 As shown, in some embodiments, the mounting hole 25 extends through the first cylindrical portion 40 and the second cylindrical portion 50. This makes the first cylindrical portion 40, the second cylindrical portion 50, and the mounting hole 25 fit together more tightly.
[0092] Please see Figure 15In some embodiments, the adapter 200 connects the frames 20 of two adjacent photovoltaic devices 100 so that the two adjacent photovoltaic devices 100 are rotatably connected. In this way, the frame 20 can provide an installation position for the adapter 200, so that the two adjacent photovoltaic devices 100 can be rotatably connected through the adapter 200.
[0093] In one example, as discussed above, long member 211 forms the long edge of frame 20, short member 212 forms the short edge of frame 20, and connector 22 connects adjacent long member 211 and short member 212. Therefore, frame 20 includes two long edges and two short edges, the two long edges are arranged opposite each other, and the two short edges are located between the two long edges. Adapter 200 can connect the long edge of frame 20, or in other words, adapter 200 can connect the long member 211 of frame 20, thereby making the center of gravity of photovoltaic device 1000 lower in the folded state and more convenient to transport.
[0094] Please see Figure 15 For ease of description, two adjacent photovoltaic devices 100 are respectively the first photovoltaic device 101 and the second photovoltaic device 102. In some embodiments, the adapter 200 includes a first rotating member 201, a second rotating member 202 and a rotating shaft 203. The first rotating member 201 and the second rotating member 202 are rotatably connected through the rotating shaft 203. 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.
[0095] Alternatively, 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 make the first photovoltaic device 101 and the second photovoltaic device 102 rotatably connected.
[0096] In some embodiments, when the photovoltaic device 1000 is in the unfolded state, the first rotating member 201 abuts against one side of the second photovoltaic device 102, and the second rotating member 202 abuts against one side of the first photovoltaic device 101, so that a predetermined angle is formed between the two adjacent photovoltaic devices 100. Thus, the photovoltaic device 1000 is convenient to store and transport when folded, and when unfolded, the angle between the two adjacent photovoltaic devices 100 is limited to a predetermined angle by the adapter 200, keeping the photovoltaic device 1000 stable and increasing the light-receiving area of the photovoltaic device 100, which is beneficial for the photovoltaic device 1000 to convert solar energy into electrical energy.
[0097] 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.
[0098] In this way, the first photovoltaic device 101 and the second photovoltaic device 102 can be limited by their own frame 20 to form a predetermined angle α, which can make the structure of the adapter 200 fit together and make the unfolded state of the first photovoltaic device 101 and the second photovoltaic device 102 stable, which is conducive to the photovoltaic equipment 1000 converting solar energy into light energy.
[0099] In some embodiments, to facilitate the use of the photovoltaic device 1000, the first rotating member 201 and the second rotating member 202 are rotatable and detachably connected, which makes the photovoltaic device 100 detachable, which is beneficial for the photovoltaic device 100 to be used alone or transported.
[0100] Please see Figures 15-18 In some embodiments, the first rotating member 201 is provided with a first transition hole 2011, and the second rotating member 202 is provided with a second transition hole 2021 coaxially arranged with the first transition hole 2011. The rotating shaft 203 is movably inserted into the first transition hole 2011 and the second transition hole 2021. Thus, the first transition hole 2011 and the second transition hole 2021 facilitate the installation of the rotating shaft 203, thereby enabling the first rotating member 201 and the second rotating member 202 to be rotatably connected.
[0101] Please see Figures 15-18 In some embodiments, the first rotating member 201 is provided with a slot 2012, and a first adapter hole 2011 communicates with the slot 2012. There are two first adapter holes 2011, located on opposite sides of the slot 2012. There are also two rotating shafts 203, spaced apart in second adapter holes 2021. The second rotating member 202 is partially housed in the slot 2012, and the rotating shaft 203 extends from the second adapter hole 2021 and is inserted into a corresponding first adapter hole 2011. This arrangement, with the second rotating member 202 partially housed in the slot 2012 and the rotating shaft 203 extending from the second adapter hole 2021 and being inserted into a corresponding first adapter hole 2011, makes the structure of the adapter 200 more compact and allows for smoother rotation of the first rotating member 201 and the second rotating member 202.
[0102] Please see Figures 15-18In some embodiments, the adapter 200 includes a handle 204 connected to the rotating shaft 203. The second rotating member 202 has a clearance groove 2022 for the handle 204 to move. The clearance groove 2022 communicates with the second adapter hole 2021 and extends along the axial direction of the second adapter hole 2021. Thus, the handle 204 facilitates operation of the adapter 200 to move the rotating shaft 203, thereby allowing the first rotating member 201 and the second rotating member 202 to be disassembled and assembled together, which is beneficial for the use of the photovoltaic device 100. Specifically, the handle 204 can be cylindrical, and one end of the handle 204 can be inserted into the rotating shaft 203, thereby ensuring a stable connection between the handle 204 and the rotating shaft 203. The axial direction of the handle 204 is approximately perpendicular to the axial direction of the rotating shaft 203, making it easier for the handle 204 to move the rotating shaft 203.
[0103] Please see Figures 15-18 In some embodiments, the adapter 200 further includes an elastic element 205 disposed in the second adapter hole 2021. The elastic element 205 connects two rotating shafts 203. When an external force is applied to the handle 204, the two rotating shafts 203 move closer to each other and retract into the second adapter hole 2021, and the elastic element 205 is compressed. After the external force is unloaded, the elastic element 205 applies an elastic force to the two rotating shafts 203, causing the rotating shafts 203 to extend out of the second adapter hole 2021. In this way, the elastic element 205 makes it easier to assemble the first rotating member 201 and the second rotating member 202, and allows the rotating shafts 203 to remain simultaneously inserted into the first adapter hole 2011 and the second adapter hole 2021, which is beneficial for the first rotating member 201 and the second rotating member 202 to rotate more stably and smoothly.
[0104] Specifically, the elastic element 205 is, for example, a helical elastic element. It can be understood that, since the pivot 203 is connected to the handle 204, the pivot 203 is at least partially retained in the second transition hole 2021 under the limiting action of the handle 204 and the groove wall of the clearance groove 2022.
[0105] In one example, when assembling two photovoltaic devices 100, the two handles 204 can be pinched together by hand, that is, the two handles 204 are brought close together so that the two rotating shafts 203 are retracted into the second adapter hole 2021. After the first rotating hole 2011 is aligned with the second adapter hole 2021, the hand is released. Under the action of the elastic element 205, the rotating shaft 203 extends from the second adapter hole 2021 into the first adapter hole 2011, thereby assembling the two photovoltaic devices 100 together.
[0106] Please see Figures 15-18In some embodiments, when the photovoltaic device 1000 is in the unfolded state, the first rotating member 201 abuts against the frame 20 of the second photovoltaic device 102, and the second rotating member 202 abuts against the frame 20 of the first photovoltaic device 101, so that a predetermined angle α is formed between the first photovoltaic device 101 and the second photovoltaic device 102. Thus, 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, which is beneficial for maintaining the stability of the state of the first photovoltaic device 101 and the second photovoltaic device 102.
[0107] Please see Figures 15-18 In some embodiments, the first rotating member 201 includes a first connecting part 2013, a first mounting part 2014, and a first abutting part 2015. The first mounting part 2014 and the first abutting part 2015 are both connected to the first connecting part 2013. The first mounting part 2014 is fixedly connected to the frame 20 of the first photovoltaic device 101. The first connecting part 2013 is provided with a first connecting hole 2011. The first abutting part 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.
[0108] The second rotating member 202 includes a second connecting part 2023, a second mounting part 2024, and a second abutting part 2025. Both the second mounting part 2024 and the second abutting part 2025 are connected to the second connecting part 2023. The second mounting part 2024 is fixedly connected to the frame 20 of the second photovoltaic device 102. The second connecting part 2023 has a second connecting hole 2021. The second abutting part 2025 abuts against the frame 20 of the first photovoltaic device 101 when the first photovoltaic device 101 and the second photovoltaic device 102 are unfolded. Thus, the first abutting part 2015 and the second abutting part 2025 can achieve angular limiting between the first photovoltaic device 101 and the second photovoltaic device 102, and the first mounting part 2014 and the second mounting part 2024 can stably connect the first rotating member 201 and the second rotating member 202 to their respective frames 20.
[0109] Specifically, the first mounting part 2014 and the second mounting part 2024 can be in the form of a sheet, and the first mounting part 2014 and the second mounting part 2024 can be fixedly connected to the corresponding frame 20 by fasteners such as screws.
[0110] In some embodiments, the first rotating member 201 and the second rotating member 202 are connected to the long edge of the corresponding frame 20. This results in a lower center of gravity for the photovoltaic device 1000 in its folded state, making transport 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.
[0111] In one embodiment, the photovoltaic device 100 includes a photovoltaic panel 10, a junction box 30, and a first cylindrical portion 40. The photovoltaic panel 10 includes a substrate 11, solar cells 12, and a light-transmitting cover plate 13. The solar cells 12 are disposed on the substrate 11, and the light-transmitting cover plate 13 covers the solar cells 12. The junction box 30 is disposed on the light-transmitting cover plate 13. The first cylindrical portion 40 is disposed on one side of the light-transmitting cover plate 13, and the first cylindrical portion 40 is used to form a receiving space between the two photovoltaic devices 100 to accommodate the junction box 30 when two photovoltaic devices 100 are stacked.
[0112] Thus, the junction box 30 is set on the light-transmitting cover plate 13, making the photovoltaic device 100 convenient to use during operation, eliminating the need to connect wires from the back of the photovoltaic device 100. In addition, the first cylindrical portion 40 forms a receiving space between the two photovoltaic devices 100 to accommodate the junction box 30, which can reduce interference between the junction box 30 and other photovoltaic devices 100 and improve the service life of the photovoltaic device 100.
[0113] In summary, in some embodiments, the photovoltaic device 1000 includes multiple photovoltaic devices 100 and an adapter 200. Each photovoltaic device 100 includes a photovoltaic panel 10 and a frame 20, with the frame 20 covering the edge of the photovoltaic panel 10. The adapter 200 connects two adjacent photovoltaic devices 100 and includes a first rotating member 201 and a second rotating member 202 rotatably connected to the first rotating member 201. 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 two adjacent photovoltaic devices 100 are maintained at a predetermined angle by the adapter 200. Thus, 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, the illumination area of the photovoltaic device 100 increases, which is beneficial for the photovoltaic device 1000 to convert solar energy into electrical energy.
