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.

[0031] 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.

[0032] 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.

[0033] See also Figures 1-4The photovoltaic device 1000 according to the embodiment of the present application includes a photovoltaic device 100 and an adapter assembly 300. The adapter assembly 300 includes an adapter 200 and a clamping member 30. 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.

[0034] 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.

[0035] 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 1 When the photovoltaic device 1000 is in the unfolded state, a predetermined angle α is formed between two adjacent photovoltaic devices 100. For example, when the photovoltaic device 1000 is in the unfolded state, the predetermined angle α is maintained between two adjacent photovoltaic devices 100 by the adapter 200.

[0036] In this way, the photovoltaic device 1000 is convenient to store and transport when it is 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.

[0037] 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.

[0038] 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°.

[0039] 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.

[0040] like Figure 4 As shown, in some embodiments, the photovoltaic device 100 may include a photovoltaic panel 10 and a frame 20, and the photovoltaic panel 10 is set 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.

[0041] 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, so that the two adjacent photovoltaic devices 100 can be rotatably connected through the adapter 200.

[0042] See also Figure 4 In some embodiments, the adapter 200 enables two adjacent photovoltaic devices 100 to be rotatably connected. The adapter 200 includes a connecting column 210, which is passed through the photovoltaic device 100. The clamping member 30 is clamped on the connecting column 210 to enable the adapter 200 to be installed and fixed on the photovoltaic device 100.

[0043] In this way, the connecting column 210 of the adapter 200 is passed through the photovoltaic device 100, and the clamping member 30 is clamped on the connecting column 210 to install and fix the adapter 200 on the photovoltaic device 100. This makes the installation method of the adapter 200 and the photovoltaic device 100 simple, which is conducive to the assembly and use of multiple photovoltaic devices 100.

[0044] Specifically, the connecting post 210 is provided through the photovoltaic device 100 along the thickness direction of the photovoltaic device 100. Furthermore, the connecting post 210 can be provided through the frame 20 of the photovoltaic device 100. The clamping member 30 is clamped on the connecting post 210, thereby restricting the movement of the connecting post 210 along the thickness direction of the photovoltaic device 100. In turn, the adapter 200 does not move relative to the photovoltaic device 100, allowing the adapter 200 to be installed and fixed on the photovoltaic device 100.

[0045] It can be understood that compared with the adapter 200 being installed by means of screws or the like, the clamping member 30 is connected to the connecting column 210 by means of a clamping connection, and the adapter 200 is more convenient to install.

[0046] See also Figure 5-Figure 7In some embodiments, the connecting post 210 is provided with a limiting groove 211, and the clamping member 30 is provided with a through hole 31, and the clamping member 30 is clamped in the limiting groove 211 through the through hole 31. In this way, the clamping member 30 can be stably clamped on the connecting post 210. Specifically, the limiting groove 211 can be an annular groove. The dimension between the limiting groove 211 and the photovoltaic device 100 can be equal to the thickness of the clamping member 30, so that after the clamping member 30 is clamped in the limiting groove 211, the clamping member 30 can abut against the photovoltaic device 100, thereby reducing the shaking of the adapter 200 after installation.

[0047] See also Figure 5-Figure 7 In some embodiments, the clamping member 30 is a sheet-like member, and the through hole 31 passes through both sides of the clamping member 30 in the thickness direction. The clamping member 30 is provided with a channel 32 passing through the through hole 31 and the edge of the clamping member 30. The channel 32 makes the portion of the clamping member 30 located on one side of the through hole 31 elastic.

[0048] In this way, the clamping member 30 can be inserted into the limiting groove 211 through the channel 32, making the installation process of the clamping member 30 more convenient. Specifically, during the installation process of the clamping member 30, the opening of the channel 32 can be directed toward the limiting groove 211, and then an external force is applied to the clamping member 30 in the direction of the limiting groove 211, so that the clamping member 30 partially elastically deforms to increase the width of the channel 32, thereby causing the clamping member 30 to be inserted into the limiting groove 211 after the channel 32 passes through the connecting column 210.

[0049] See also Figure 7 In some embodiments, the width of the channel 32 decreases from the edge of the clamping member 30 toward the through-hole 31. This prevents the clamping member 30 from falling out after being engaged with the retaining groove 211. Specifically, the minimum width of the channel 32 is smaller than the diameter of the through-hole 31 and also smaller than the diameter of the connecting post 210, allowing the clamping member 30 to remain engaged with the connecting post 210 without external force.

[0050] For the convenience of description, two adjacent photovoltaic devices 100 are respectively a first photovoltaic device 101 and a second photovoltaic device 102. Figure 2 、 Figure 5-Figure 7 In some embodiments, the adapter 200 includes a first rotating member 201 and a second rotating member 202. The first rotating member 201 is rotatably connected to the second rotating member 202. The first rotating member 201 is fixed to the first photovoltaic device 101, and the second rotating member 202 is fixed to the second photovoltaic device 102. For example, the first rotating member 201 is fixed to the frame 20 of the first photovoltaic device 101, and the second rotating member 202 is fixed to the frame 20 of the second photovoltaic device 102.

[0051] In other words, the first rotating member 201 is fixed on one of the two adjacent photovoltaic devices 100, and the second rotating member 202 is fixed on the other photovoltaic device 100. The first rotating member 201 and the second rotating member 202 are both provided with a connecting column 210, and the connecting column 210 is passed through the corresponding photovoltaic device 100.

[0052] 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. In addition, the first rotating member 201 and the second rotating member 202 are both provided with a connecting post 210, so that the first rotating member 201 and the second rotating member 202 can be installed on the corresponding photovoltaic device 100 through the clamping member 30.

[0053] 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.

[0054] See also Figure 5-Figure 7 In some embodiments, the first rotating member 201 is provided with a first adapter hole 2011, and the second rotating member 202 is provided with a second adapter hole 2021 coaxially disposed with the first adapter hole 2011. The adapter member 200 further includes a rotating shaft 203, which is movably inserted into the first adapter hole 2011 and the second adapter hole 2021. Thus, the first adapter hole 2011 and the second adapter hole 2021 facilitate the installation of the rotating shaft 203, thereby rotatably connecting the first rotating member 201 and the second rotating member 202.

[0055] See also Figure 5-Figure 7 In some embodiments, the first rotating member 201 is provided with a card slot 2012, the first adapter hole 2011 is connected to the card slot 2012, the number of the first adapter holes 2011 is two, and the two first adapter holes 2011 are respectively located on both sides of the card slot 2012, the number of the rotating shafts 203 is two, and the two rotating shafts 203 are arranged at intervals in the second adapter hole 2021, the second rotating member 202 is partially accommodated in the card slot 2012, and the rotating shaft 203 extends from the second adapter hole 2021 and is inserted into a corresponding first adapter hole 2011.

[0056] In this way, the second adapter 202 is partially accommodated in the card slot 2012, and the rotating shaft 203 extends from the second adapter hole 2021 and is inserted into a corresponding first adapter hole 2011, which makes the structure of the adapter 200 more compact and makes the first rotating member 201 and the second rotating member 202 rotate more smoothly.

[0057] See also Figure 4-Figure 7In some embodiments, the adapter 200 includes a handle 204 connected to the rotating shaft 203, and the second rotating member 202 is provided with an avoidance groove 2022 for the movement of the handle 204, and the avoidance groove 2022 is connected to the second adapter hole 2021 and extends along the axial direction of the second adapter hole 2021.

[0058] In this way, handle 204 facilitates operation of adapter 200, thereby moving shaft 203 and, in turn, allowing disassembly and assembly of first rotating member 201 and second rotating member 202, facilitating the use of photovoltaic device 100. Specifically, handle 204 can be cylindrical, with one end of handle 204 inserted into shaft 203, thereby ensuring a stable connection between handle 204 and shaft 203. The axial direction of handle 204 is substantially perpendicular to the axial direction of shaft 203, making it easier for handle 204 to move shaft 203.

[0059] See also Figure 7 In some embodiments, the adapter 200 further includes an elastic member 205 disposed in the second adapter hole 2021. The elastic member 205 connects the two rotating shafts 203. When an external force is applied to the handle 204, the two rotating shafts 203 approach each other and retract into the second adapter hole 2021, and the elastic member 205 is compressed. After the external force is unloaded, the elastic member 205 applies an elastic force to the two rotating shafts 203 so that the rotating shafts 203 extend out of the second adapter hole 2021.

[0060] In this way, the elastic member 205 makes it easier to assemble the first rotating member 201 and the second rotating member 202, and can keep the rotating shaft 203 inserted into the first adapter hole 2011 and the second adapter hole 2021 at the same time, which is conducive to more stable and smooth rotation of the first rotating member 201 and the second rotating member 202.

[0061] Specifically, the elastic member 205 is an elastic element such as a coil spring. It is understood that since the shaft 203 is connected to the handle 204, the shaft 203 is at least partially retained in the second adapter hole 2021 under the limiting action of the handle 204 and the groove wall of the avoidance groove 2022.

[0062] In one example, when assembling two photovoltaic devices 100, the two handles 204 can be pinched by hand, that is, the two handles 204 are brought close to each other 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, release your hands. Under the action of the elastic member 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.

[0063] See also Figures 1-4In 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, thereby forming 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 angle between two adjacent photovoltaic devices 100 is limited to a predetermined angle by the adapter 200, maintaining the stability of the photovoltaic device 1000 and increasing the illuminated area of ​​the photovoltaic devices 100, thereby facilitating the photovoltaic device 1000's conversion of solar energy into electrical energy.

[0064] For example, when the photovoltaic device 1000 is in the deployed 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. In this way, 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 helps to maintain the stability of the first photovoltaic device 101 and the second photovoltaic device 102.

[0065] See also Figure 5-Figure 7 In some embodiments, the photovoltaic device 1000 can be in a folded state and an unfolded state. 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 provided with a connecting column 210. The first adapter portion 2013 is provided with a first adapter hole 2011.

[0066] 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 provided with a connecting column 210. The second mounting portion 2024 is provided with a second adapter hole 2021. When the photovoltaic device 1000 is in the unfolded state, the first abutting portion 2015 abuts against the second photovoltaic device 102, and the second abutting portion 2025 abuts against the first photovoltaic device 101, so that the two adjacent photovoltaic devices 100 are maintained at a predetermined angle through the adapter 200.

[0067] In this way, the first abutment portion 2015 and the second abutment portion 2025 can realize the angle limitation 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 make the first rotating member 201 and the second rotating member 202 stably connected to the corresponding frame 20.

[0068] Specifically, the first mounting portion 2014 and the second mounting portion 2024 may be sheet-shaped, and the first mounting portion 2014 and the second mounting portion 2024 may be fixedly connected to the corresponding frame 20 via the connecting column 210 and the clamping member 30 .

[0069] 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. In this way, the center of gravity of the photovoltaic device 1000 is lower when in the folded state, making transportation more convenient.
