[0035] Please refer to Figures 1 - 2 , the photovoltaic device 100 of the embodiment of the present application includes a photovoltaic panel 10, a frame 20, and an elastic block 30. The frame 20 wraps the edge of the photovoltaic panel 10. The frame 20 includes two long edges 201 and two short edges 202. The two long edges 201 of the frame 20 are disposed opposite to each other, and the two short edges 202 of the frame 20 are located between the two long edges 201 of the frame 20; the elastic block 30 is disposed on the long edge of the frame 20 and / or at the corner portion of the frame 20, and the elastic block 30 protrudes from the outer surface of the frame 20.

[0036] In the photovoltaic device 100 of the above embodiment, the frame 20 wraps the edge of the photovoltaic panel 10, which can protect the photovoltaic panel 10; in addition, the elastic block 30 can absorb the impact received by the photovoltaic device 100 during the use of the photovoltaic device 100, reduce the risk of damage to the photovoltaic device 100, and improve the service life of the photovoltaic device 100.

[0037] Specifically, the photovoltaic panel 10 is a component for converting solar energy into light energy. The photovoltaic panel 10 is generally in the shape of a rectangular plate. The frame 20 is disposed at the edge of the photovoltaic panel 10 and wraps the edge of the photovoltaic panel 10, which can reduce the impact received by the photovoltaic panel 10. The hardness of the elastic block 30 is less than the hardness of the frame 20. The elastic block 30 protrudes from the outer surface of the frame 20. During the use of the photovoltaic device 100, the elastic block 30 can contact the outside first, reducing the impact received by the photovoltaic panel 10.

[0038] The elastic block 30 is disposed on the long edge 201 of the frame 20 and / or at the corner portion of the frame 20, including three cases:

[0039] First, the elastic block 30 is disposed on the long edge 201 of the frame 20;

[0040] Second, the elastic block 30 is disposed at the corner portion of the frame 20;

[0041] Third, the elastic block 30 is disposed on the long edge 201 of the frame 20 and at the corner portion of the frame 20.

[0042] Please refer to Figure 3 In some embodiments, the elastic block 30 includes a rubber block, and the elastic block 30 is at least partially embedded in the frame 20. Or rather, the elastic block 30 and the frame 20 are integrally formed, and the elastic block 30 can be assembled on the frame 20. In this way, the installation of the elastic block 30 is convenient, which can reduce the manufacturing cost of the photovoltaic device 100. Since the elastic block 30 can be a rubber block, and the rubber block has the characteristics of wear resistance and low cost, the service life of the elastic block 30 can be improved and the cost of the photovoltaic device 100 can be reduced.

[0043] In some embodiments, the elastic block 30 is configured to be able to abut against the bearing surface when the photovoltaic device 100 is inclined relative to the bearing surface at a preset angle. In this way, the elastic block 30 supports the photovoltaic device 100 during the use of the photovoltaic device 100, improves the stability of the photovoltaic device 100, and further improves the power generation efficiency of the photovoltaic device 100. In addition, the photovoltaic device 100 is inclined relative to the bearing surface. On the premise of not reducing the power generation power, on the one hand, the floor area of the photovoltaic device 100 can be saved; on the other hand, when there are obstacles such as leaves on the photovoltaic device 100, the obstacles such as leaves can slide off the surface of the photovoltaic device 100, avoiding the reduction of the power generation power caused by the local occlusion of the photovoltaic device 100.

[0044] Please refer to Figures 1 - 2 In some embodiments, the number of the elastic blocks 30 is multiple, and the multiple elastic blocks 30 are respectively arranged on two opposite sides of the frame 20. The elastic blocks 30 located on two opposite sides of the frame 20 are symmetrically arranged with respect to the thickness median plane of the photovoltaic panel 10, and the thickness median plane is equidistant from the two surfaces in the thickness direction of the photovoltaic panel 10. In this way, the multiple elastic blocks 30 are respectively arranged on two opposite sides of the frame 20, so that when the photovoltaic device 100 is used in different states, the elastic blocks 30 can reduce the impact on the photovoltaic device 100.

[0045] In some embodiments, the elastic block 30 is a solid structure. In this way, the hardness of the elastic block 30 is relatively large, it is more wear-resistant, and the service life is longer.

[0046] In one embodiment, the photovoltaic panel 10 may include a substrate 11, a battery cell 12, and a light-transmitting cover plate 13. The battery cell 12 is disposed on the substrate 11, and the light-transmitting cover plate 13 covers the battery cell 12. Specifically, the substrate 11 can be made of materials such as PET, CPC, fiberglass board, and glass. The substrate 11 can be a sheet such as a rectangle or a rounded rectangle. The battery cell 12 can be fixed on the substrate 11 by means of adhesion. The battery cell 12 is used to convert light energy into solar energy. The number of the battery cells 12 can be multiple, and the multiple battery cells 12 are arranged in an array. For example, the row arrangement direction of the battery cells 12 is the same as the length direction of the substrate 11. The column arrangement direction of the battery cells 12 is the same as the width direction of the substrate 11.

[0047] The light-transmitting cover plate 13 can be made of materials such as PET, CPC, and glass, and the light-transmitting cover plate 13 can have the same shape and size as the substrate 11. The light-transmitting cover plate 13 can be bonded to the substrate 11 or the solar cell 12 by bonding.

[0048] Please refer to Figures 4 - 6 , in some embodiments, the frame 20 is used to abut against the bearing surface, so that the photovoltaic device 100 can abut against the bearing surface. The bearing surface is, for example, the ground. The frame 20 can include a plurality of enclosing members 21 and a plurality of connecting members 22. The enclosing members 21 and the connecting members 22 are connected end to end to form a ring, and the connecting member 22 is detachably inserted into two adjacent enclosing members 21. The connecting member 22 is provided at the transition part of the frame 20.

[0049] In this way, the enclosing members 21 and the connecting members 22 of the frame 20 are detachably connected by inserting, so that the frame 20 is easy to assemble, and it is easier to wrap the edge of the photovoltaic panel 10, so that the photovoltaic panel 10 and the frame 20 are easy to assemble and disassemble.

[0050] Specifically, the enclosing members 21 and the connecting members 22 can be made of materials with relatively high strength such as aluminum alloy, so as to improve the impact resistance of the frame 20 and be beneficial to protecting the photovoltaic panel 10.

[0051] In some embodiments, the enclosing member 21 is in a straight strip shape, and the connecting member 22 forms the corner part of the frame 20. Since the manufacturing process of forming the corner part of the frame 20 with relatively large-sized parts is difficult, therefore, the frame 20 is made in a straight strip shape, and the connecting member 22 forms the corner part of the frame 20, which can reduce the manufacturing difficulty of the frame 20.

[0052] Please refer to Figures 4 - 6 , in some embodiments, the enclosing 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 connecting member 22 connects the adjacent long member 211 and short member 212. In this way, the connecting member 22 can connect the long member 211 and the short member 212 to form the frame 20. Specifically, the number of both the long member 211 and the short member 212 is two, and the number of the connecting members 22 is four. The two long members 211 are arranged substantially in parallel, and the two short members 212 are arranged substantially in parallel.

[0053] Please refer to Figure 6, in some embodiments, the connecting member 22 includes a connecting portion 221 and a plugging portion 222 connected to the connecting portion 221. The surrounding member 21 is provided with a plugging hole 210, and the plugging portion 222 is inserted into the plugging hole 210, and the connecting portion 221 is butted against the surrounding member 21. Thus, the cooperation between the plugging hole 210 and the plugging portion 222 enables the connecting member 22 and the surrounding member 21 to be easily plugged together.

[0054] In some embodiments, the plugging hole 210 extends along the length direction of the surrounding member 21. Optionally, the plugging hole 210 may penetrate through both ends of the surrounding member 21 along the length direction of the surrounding member 21. Thus, the plugging hole 210 can reduce the weight of the surrounding member 21, thereby reducing the weight of the frame 20, which is beneficial to the transportation of the photovoltaic device 100.

[0055] Please refer to Figure 6 , in some embodiments, the plugging portion 222 is provided with a threaded hole 223, and the surrounding member 21 is provided with a through hole 213. The surrounding member 21 and the plugging portion 222 are fixed by screwing a threaded fastener through the through hole 213 and the threaded hole 223. Thus, the surrounding member 21 and the connecting portion 221 are more stably connected, reducing the risk of loosening of the frame 20.

[0056] Please refer to Figure 6 , in some embodiments, the frame 20 is provided with a mounting groove 24 spaced apart from the plugging hole 210. The notch of the mounting groove 24 faces away from the plugging hole 210. The mounting groove 24 extends along the frame 20 and penetrates through the surrounding member 21 and the connecting portion 221. The mounting groove 24 is used for mounting the photovoltaic panel 10. Thus, 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.

[0057] In one example, during the assembly process of the photovoltaic device 100, the surrounding member 21 and the connecting member 22 can be sequentially clamped on the edge of the photovoltaic panel 10 through the mounting groove 24, and then the surrounding member 21 and the connecting member 22 are locked with screws, so that the structure of the frame 20 is stable. Finally, glue is injected into the mounting groove 24 to bond the frame 20 and the photovoltaic panel 10 with the glue, improving the stability of the photovoltaic device 100.

[0058] Please refer to Figure 1 , in certain embodiments, the photovoltaic device 100 includes a junction box 40. The junction box 40 is disposed on the photovoltaic panel 10, and the junction box 40 is electrically connected to the photovoltaic panel 10. Thus, the junction box 40 can facilitate the electrical connection between the photovoltaic device 100 and external devices.

[0059] Specifically, the number of junction boxes 40 for each photovoltaic panel 10 can be two. The junction box 40 can include a first junction box 41 and a second junction box 42, and both the first junction box 41 and the second junction box 42 are electrically connected to the photovoltaic panel 10. Two adjacent photovoltaic devices 100 are electrically connected through the first junction box 41 and the second junction box 42.

[0060] Please refer to Figures 7 - 10 , the photovoltaic device 1000 of the embodiment of the present application includes a plurality of photovoltaic devices 100. For example, the number of photovoltaic devices 100 can be 2, 4, 5, 6, 8, etc. Two adjacent photovoltaic devices 100 are rotatably connected. Specifically, the photovoltaic device 1000 further includes an adapter 200. The plurality of photovoltaic devices 100 can be rotatably connected through 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 the photovoltaic device 100 has a long edge and a short edge substantially perpendicular to the long edge.

[0061] 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 said photovoltaic device 100 is used to abut against the bearing surface. Or, a plurality of photovoltaic devices 100 can be detachably connected end to end in sequence. For example, a plurality of photovoltaic devices 100 are detachably connected end to end in sequence along the width direction of the photovoltaic device 100, that is, the long edges of a plurality of photovoltaic devices 100 can be detachably connected through the adapter 200, which is beneficial to the assembly and disassembly of the photovoltaic device 1000 and facilitates the use of the photovoltaic device 1000.

[0062] Since a plurality of photovoltaic devices 1000 are rotatably connected, the photovoltaic device 1000 can be in a folded state and an unfolded state. When the photovoltaic device 1000 is in the folded state, a plurality of photovoltaic devices 100 are stacked, as Figure 8 shown. When the photovoltaic device 1000 is in the unfolded state, a predetermined angle α is formed between two adjacent photovoltaic devices 100, as Figure 2 shown. Exemplarily, when the photovoltaic device 1000 is in the unfolded state, two adjacent photovoltaic devices 100 are held at a predetermined angle through the adapter 200. In this way, the photovoltaic device 1000 is convenient for storage and transportation 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 is stable, the light receiving area of the photovoltaic device 100 is increased, and it is beneficial for the photovoltaic device 1000 to convert solar energy into electric energy.

[0063] In one example, the predetermined angle α is, for example, 120° - 150°. For example, the predetermined angle α can be angles such as 120°, 125°, 130°, 140°, or 150°. In this way, the area where the photovoltaic device 100 unfolds is relatively large, which is beneficial for the photovoltaic device 1000 to convert solar energy into electrical energy.

[0064] 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 angles such as 50°, 60°, or 70°.

[0065] The adjacent photovoltaic devices 100 are inclined with respect to the bearing surface. On the premise of not reducing the power generation efficiency, on the one hand, the floor area occupied by the photovoltaic device 1000 can be saved; on the other hand, when there are obstacles such as leaves on the photovoltaic device 100, the obstacles such as leaves can slide off the surface of the photovoltaic device 100, avoiding the reduction of power generation efficiency caused by partial occlusion of the photovoltaic device 100.

Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of the described features.
