[0033] Please refer to Figures 1 - 3 , the photovoltaic device 100 of the embodiment of the present application includes a frame 20, a photovoltaic panel 10, and a buckle 30. The photovoltaic panel 10 is disposed on the frame 20; the buckle 30 penetrates through the frame 20 and the photovoltaic panel 10 and buckles the photovoltaic panel 10 and the frame 20 together.

[0034] In the photovoltaic device 100 of the embodiment of the present application, the buckle 30 penetrates through the frame 20 and the photovoltaic panel 10 and buckles the photovoltaic panel 10 and the frame 20 together, so that the photovoltaic panel 10 and the frame 20 can be quickly assembled together, and the installation efficiency of the photovoltaic panel 10 is high.

[0035] Specifically, the photovoltaic panel 10 is a component for converting solar energy into light energy. The photovoltaic panel 10 is integrally in the shape of a rectangular plate. The frame 20 can be disposed at the edge of the photovoltaic panel 10 and is used to carry the photovoltaic panel 10, which can reduce the impact on the photovoltaic panel 10. The buckle 30 buckles the photovoltaic panel 10 and the frame 20 together by a buckling method, so that the photovoltaic panel 10 and the frame 20 can form a whole.

[0036] In the embodiment of the present application, the photovoltaic panel 10 and the frame 20 are respectively buckled and connected to the buckle 30. The buckle 30 can limit the relative position between the photovoltaic panel 10 and the frame 20, and further fix the relative position of the photovoltaic panel 10 and the frame 20.

[0037] It can be understood that the frame 20 and the photovoltaic panel 10 are respectively formed with through holes, so that the buckle 30 can penetrate through the frame 20 and the photovoltaic panel 10.

[0038] Please refer to Figure 3 , in some embodiments, the frame 20 includes a frame body 21 and a support flange 22 connecting the frame body 21. The frame body 21 and the support flange 22 enclose an installation groove 210. The photovoltaic panel 10 is located in the installation groove 210 and abuts against the support flange 22. The buckle 30 penetrates through the support flange 22 and the photovoltaic panel 10.

[0039] In this way, the supporting flange 22 can stably support the photovoltaic panel 10. Additionally, the photovoltaic panel 10 is located in the installation groove 210, such that the photovoltaic panel 10 does not protrude from the surface of the frame 20, which is beneficial for reducing the impact on the photovoltaic panel 10 and improving the lifespan of the photovoltaic device 100.

[0040] Specifically, the frame body 21 is integrally annular, and the supporting flange 22 extends from the inner edge of the frame body 21 into the space enclosed by the frame body 21. The supporting flange 22 can be annular. Of course, the supporting flange 22 can be sheet-shaped and there can be multiple of them, and the multiple supporting flanges 22 can be arranged at intervals along the circumferential direction of the frame body 21. To improve the production efficiency of the frame 20, the frame body 21 and the supporting flange 22 can be an integrally formed structure.

[0041] Please refer to Figure 2 and Figure 3 , in some embodiments, the supporting flange 22 is provided with through holes 221, and the through holes 221 penetrate the supporting flange 22 along the thickness of the supporting flange 22 and communicate with the installation groove 210.

[0042] In this way, the through holes 221 can reduce the weight of the frame 20, making the photovoltaic device 100 easy to handle and increasing the application range of the photovoltaic device 100. Additionally, the through holes 221 can save the material of the frame 20 and reduce the production cost of the frame 20.

[0043] Please refer to Figure 3 and Figure 4 , in some embodiments, the fastener 30 includes a base portion 31, a connecting portion 32, and a fastening portion 33. The base portion 31 and the fastening portion 33 are respectively connected to opposite ends of the connecting portion 32. The base portion 31 abuts against the frame 20, the connecting portion 32 passes through the frame 20 and the photovoltaic panel 10, and the fastening portion 33 is fastened to the surface of the photovoltaic panel 10 facing away from the base portion 31.

[0044] In this way, the fastening portion 33 and the base portion 31 can cooperate with each other, such that the photovoltaic panel 10 and the frame 20 can be clamped between the fastening portion 33 and the base portion 31, thereby making the photovoltaic panel 10 and the frame 20 form an integral body.

[0045] Specifically, the base portion 31 is sheet-shaped. The base portion 31 can abut against the supporting flange 22 of the frame 20. The connecting portion 32 is column-like, and the connecting portion 32 can pass through the supporting flange 22 of the frame 20 and the photovoltaic panel 10. The fastening portion 33 is connected to one end of the connecting portion 32 and protrudes transversely from the connecting portion 32.

[0046] In one example, during the installation of the photovoltaic device 100, the photovoltaic panel 10 can be first placed on the frame 20, and then the fastening portion 33 of the fastening member 30 is passed through the frame 20 and the photovoltaic panel 10 in sequence from one side of the frame 20, so that the fastening portion 33 is fastened to the surface of the photovoltaic panel 10, and the base portion 31 can abut against the surface of the frame 20, thereby completing the assembly between the frame 20 and the photovoltaic panel 10.

[0047] Please refer to Figure 4 , in some embodiments, the connecting portion 32 is provided with a central hole 320. The central hole 320 extends from the end surface of the connecting portion 32 away from the base portion 31 towards the base portion 31, and the depth of the central hole 320 exceeds the height of the fastening portion 33. Thus, the central hole 320 can make the wall thickness of the connecting portion 32 smaller, which is beneficial to the deformation of the connecting portion 32, so that the fastening portion 33 can pass through the frame 20 and the photovoltaic panel 10 and be fastened to the surface of the photovoltaic panel 10.

[0048] Specifically, the central hole 320 can extend to the base portion 31. The central hole 320 can be columnar and match the surface shape of the outer contour of the connecting portion 32.

[0049] Please refer to Figure 4 , in some embodiments, the connecting portion 32 includes a first connecting section 321 and a second connecting section 322. The first connecting section 321 connects the second connecting section 322 and the base portion 31. The number of the second connecting sections 322 is multiple, and the multiple second connecting sections 322 are arranged at intervals along the circumferential direction of the first connecting section 321. A fastening portion 33 is provided at one end of each second connecting section 322 away from the base portion 31.

[0050] Thus, the multiple second connecting sections 322 are arranged at intervals along the circumferential direction of the first connecting section 321, which makes the second connecting section 322 have a larger deformation space, and is beneficial to the deformation of the second connecting section 322 during the process of passing through the frame 20 and the photovoltaic panel 10, so that the fastening portion 33 can be fastened to the surface of the photovoltaic panel 10.

[0051] Specifically, the first connecting section 321 is generally cylindrical. The second connecting section 322 is located at one end of the first connecting section 321 away from the base portion 31. The second connecting section 322 and the first connecting section 321 can be an integrally formed structure. In order to improve the elasticity of the second connecting section 322, the second connecting section 322 can be made of materials such as plastic and thin-walled metal. When the fastening member 30 is an integrally formed structure, the fastening member 30 can be made of elastic materials such as plastic and metal.

[0052] Such as Figure 4 in the embodiment of

[0053] Please refer to Figure 4 Figure 4 , in some embodiments, the buckle portion 33 includes a engaging surface 331 and a guiding surface 332. The guiding surface 332 is inclined with respect to the engaging surface 331, and the engaging surface 331 is buckled on the surface of the photovoltaic panel 10 facing away from the base portion 31.

[0054] In this way, the guiding surface 332 can enable the buckle portion 33 to pass through the frame 20 and the photovoltaic panel 10 more smoothly, so that the engaging surface 331 is buckled on the photovoltaic panel 10.

[0055] Specifically, the guiding surface 332 slopes downward from the end of the connecting portion 32 away from the base portion 31. The guiding surface 332 integrally forms a frustum circumferential surface. The engaging surface 331 is a flat surface, so that the engaging surface 331 can fit with the surface of the photovoltaic panel 10.

[0056] Please refer to Figure 1 and Figure 2 Figure 2 , in some embodiments, the number of the buckle members 30 is multiple, and the multiple buckle members 30 are arranged along the length direction of the photovoltaic panel 10.

[0057] Please refer to Figure 1 and Figure 2 Figure 2 , 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 pasting. The battery cell 12 is used to convert light energy into solar energy, and 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.

[0058] 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 battery cell 12 by means of bonding.

[0059] The buckle member 30 can be buckled on the surface of the light-transmitting cover plate 13. Specifically, the engaging surface 331 of the buckle member 30 can be buckled with the surface of the light-transmitting cover plate 13.

[0060] 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.

[0061] Please refer to Figure 1, in some embodiments, the photovoltaic device 100 includes a junction box 40, which is disposed on the photovoltaic panel 10 and electrically connected to the photovoltaic panel 10. In this way, the junction box 40 can facilitate the electrical connection between the photovoltaic device 100 and external devices.

[0062] 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.

[0063] Please refer to Figures 5 - 8 , the photovoltaic device 1000 according to 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 number of photovoltaic devices 100 is multiple, and the multiple photovoltaic devices 100 can be rotatably connected through the adapter 200. Or rather, the adapter 200 can connect two adjacent photovoltaic devices 100. The photovoltaic device 100 is integrally plate-shaped, and the photovoltaic device 100 has a long edge and a short edge that is substantially perpendicular to the long edge.

[0064] 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 the bearing surface. Or rather, multiple photovoltaic devices 100 can be detachably connected end to end in sequence. For example, multiple 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 multiple 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.

[0065] Since multiple 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, multiple 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 2As shown. Exemplarily, when the photovoltaic device 1000 is in the deployed state, two adjacent photovoltaic devices 100 are held at a predetermined angle by the adapter 200. In this way, when the photovoltaic device 1000 is folded, it is convenient for storage and transportation. When the photovoltaic device 1000 is in the deployed state, the angle between two adjacent photovoltaic devices 100 is defined by the adapter 200 as a predetermined angle, so that the state of the photovoltaic device 1000 is kept stable, the light-receiving area of the photovoltaic device 100 is increased, which is beneficial to the photovoltaic device 1000 to convert solar energy into electric energy.

[0066] 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 is deployed is relatively large, which is beneficial to the photovoltaic device 1000 to convert solar energy into electric energy.

[0067] 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°.

[0068] The adjacent photovoltaic devices 100 are inclined relative to the bearing surface. On the one hand, the floor area of the photovoltaic device 1000 can be saved without reducing the power generation efficiency. 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. In the description of the embodiments of the present invention, the meaning of "a plurality" is two or more, unless otherwise specifically defined.
