The strength and rigidity of the upper frame 1 can be increased by the reinforcement rib. The shape of the first reinforcement member 12 can be a rectangle. When in use, the first reinforcement member 12 is directly plugged into the first clip-on structure 11, which is convenient and quick, and helps to reduce the difficulty of assembling the first reinforcement member 12.

[0036] A second clamping structure 21 is provided on one side of the lower frame 2 close to the accommodating space 3. The second clamping structure 21 is used to clamp the second reinforcement member 22. The second clamping structure 21 corresponds to the first clamping structure 11.

Compared with the prior art, the risk of the laminate 41 directly bearing all the shear stresses is greatly reduced, thereby reducing the risk of explosion of the photovoltaic module 4.

[0039] Optionally, the top surface of the first flexible pad 13 is bonded to the bottom surface of part of the first reinforcement 12 by an adhesive, and the bottom surface of the first flexible pad 13 is bonded to the top surface of the photovoltaic component 4 by an adhesive.

The above-mentioned scheme is adopted, by introducing the first reinforcement 12 and the first flexible pad 13 in the upper frame 1, and the second flexible pad 23 and the second reinforcement 22 in the lower frame 2, which can not only effectively fix the photovoltaic component 4, thereby helping to enhance the protection effect of the photovoltaic component 4, but also locally strengthen the photovoltaic component 4, which is beneficial to improve the reliability of the photovoltaic component 4. At the same time, the shear stress at the edge position of the connection between the special-shaped frame 100 and the photovoltaic component 4 is subsequently reduced as much as possible, thereby minimizing the risk of explosion of the photovoltaic component 4; the first clamping structure 11 and the second clamping structure 21 are used to facilitate the clamping of the first reinforcement 12 and the second reinforcement 22, thereby reducing the assembly difficulty between the first reinforcement 12 and the upper frame 1, and between the second reinforcement 22 and the lower frame 2.

The first reinforcement member 12 is clamped between the first clamping member 110 and the second clamping member 111. The overall structure of the first clamping structure 11 is simple and practical, which makes it easy to insert the first reinforcement member 12 between the first clamping member 110 and the second clamping member 111, which is beneficial to shortening the assembly time between the first reinforcement member 12 and the first clamping structure 11, thereby improving the assembly efficiency between the first clamping structure 11 and the first reinforcement member 12. The second clip structure 21 includes a third clip 210 and a fourth clip 211 that are relatively arranged. The third clip 210 and the fourth clip 211 are arranged in mirror symmetry. Along the direction from the upper frame 1 to the lower frame 2, the cross-sectional shape of the third clip 210 is an inverted L-shaped structure. The second reinforcement member 22 is clipped between the third clip 210 and the fourth clip 211. The overall structure of the second clip structure 21 is simple and practical, which makes it easy to insert the second reinforcement member 22 between the third clip 210 and the fourth clip 211, which is beneficial to shorten the assembly time between the second reinforcement member 22 and the second clip structure 21, thereby improving the assembly efficiency between the second clip structure 21 and the second reinforcement member 22.

[0044] In an alternative embodiment, in combination Figure 1 and Figure 2 As shown, the first clamping member 110 includes a first clamping slot 1101, and the second clamping member 111 includes a second clamping slot 1111 corresponding to the first clamping slot 1101. Along the width direction of the upper frame 1, the two ends of the first reinforcing member 12 are respectively located in the first clamping slot 1101 and the second clamping slot 1111. The first clamping slot 1101 and the second clamping slot 1111 provide a placement space for the first reinforcing member 12, so as to facilitate the first reinforcing member 12 to be plugged into the first clamping member 110 and the second clamping member 111. The third clip 210 includes a third clip slot 2101, and the fourth clip 211 includes a fourth clip slot 2111 corresponding to the third clip slot 2101.

The third clip slot 2101 and the fourth clip slot 2111 provide a placement space for the second reinforcement member 22, so as to facilitate the second reinforcement member 22 to be plugged into the third clip 210 and the fourth clip 211.

[0045] It should be noted that: the first reinforcement 12 is pre-assembled between the first clip 110 and the second clip 111, and the second reinforcement 22 is pre-assembled between the third clip 210 and the fourth clip 211. When used later, there is no need to assemble the first reinforcement 12 and the first clip structure 11, and the second reinforcement 22 and the second clip structure 21 on site, which can greatly shorten the assembly time and improve the assembly efficiency between the bracket, the special-shaped frame 100 and the photovoltaic module 4.

[0046] In an alternative embodiment, continue to refer to Figure 1 and Figure 2 As shown, the first flexible pad 13 includes a first sub-portion 131 and a second sub-portion 132 connected to the first sub-portion 131, the first sub-portion 131 is located on the side of the second sub-portion 132 close to the photovoltaic module 4, specifically, the first sub-portion 131 is located below the second sub-portion 132, and a convex structure is formed between the first sub-portion 131 and the second sub-portion 132; it can be understood that: along the direction from the upper frame 1 to the lower frame 2, the cross-sectional shape of the first flexible pad 13 is a convex structure, because along the direction from the upper frame 1 to the lower frame 2, the first clamping member The cross-sectional shape of 110 and the second clamping member 111 is an L-shaped structure arranged in mirror symmetry, forming a convex structure between the first sub-portion 131 and the second sub-portion 132, which is conducive to coordinating the shape structure of the first clamping structure 11, clamping the first flexible pad 13 to the bottom of the first reinforcement member 12 between the first clamping member 110 and the second clamping member 111, and fixing the first reinforcement member 12 between the first clamping structure 11 and the first flexible pad 13, which can prevent the first reinforcement member 12 from falling off, thereby reducing the risk of explosion of the photovoltaic module 4.

[0047] The second flexible pad 23 includes a third sub-portion 231 and a fourth sub-portion 232 connected to the third sub-portion 231, the third sub-portion 231 is located on the side of the fourth sub-portion 232 close to the photovoltaic module 4, specifically, the third sub-portion 231 is located above the fourth sub-portion 232, and an inverted convex structure is formed between the third sub-portion 231 and the fourth sub-portion 232, which can be understood as: along the direction from the upper frame 1 to the lower frame 2, the cross-sectional shape of the second flexible pad 23 is an inverted convex structure, because along the direction from the upper frame 1 to the lower frame 2, the third clamping member 2 The cross-sectional shape of 10 and the fourth clamping member 211 is an inverted L-shaped structure arranged in mirror symmetry, forming an inverted convex structure between the third sub-portion 231 and the fourth sub-portion 232, which is conducive to coordinating the shape structure of the second clamping structure 21, clamping the second flexible pad 23 to the top of the second reinforcing plate 22 between the third clamping member 210 and the fourth clamping member 211, and fixing the second reinforcing member 22 between the second clamping structure 21 and the second flexible pad 23, thereby preventing the second reinforcing member 22 from falling off, thereby reducing the risk of explosion of the photovoltaic module 4.

[0048] In an alternative embodiment, continue to refer to Figure 1 and Figure 2 As shown, the width of the first reinforcement 12 along the width direction of the upper frame 1 is smaller than the width of the first sub-portion 131 along the width direction of the upper frame 1; the width of the second reinforcement 22 along the width direction of the lower frame 2 is smaller than the width of the third sub-portion 231 along the width direction of the lower frame 2.

[0049] Specifically, along the width direction of the upper frame 1, the width of the first sub-portion 131 is greater than the width of the first reinforcement 12, so that a gap can be avoided between the first clip structure 11, part of the side wall of the lower frame 2 and the photovoltaic module 4. When the laminate 41 is deformed upward or downward by the force along its own thickness direction, the edge portion of the first clip structure 11 is prevented from directly contacting the laminate 41, thereby more effectively avoiding the risk of explosion of the photovoltaic module 4 due to stress concentration.

[0050] Along the width direction of the lower frame 2, the width of the third sub-portion 231 is greater than the width of the second reinforcement 22, so as to avoid the generation of gaps between the second clip structure 21, part of the side wall of the lower frame 2 and the photovoltaic component 4. When the laminate 41 is deformed upward or downward by the force along its own thickness direction, the edge portion of the second clip structure 21 is prevented from directly contacting the protective frame 42, thereby more effectively avoiding the risk of explosion of the photovoltaic component 4 due to stress concentration.

[0051] In an alternative embodiment, continue to refer to Figure 1 and Figure 2 As shown, the upper frame 1 also includes a buckle 14, which is arranged opposite to the first buckle structure 11; the lower frame 2 also includes a connecting piece 24 connected to the second buckle structure 21, and a buckle accommodating groove 241 is provided on the connecting piece 24. The buckle 14 is snapped into the buckle accommodating groove 241. Along the direction from the upper frame 1 to the lower frame 2, the cross-sectional shape of the buckle 14 is a barb type. When the upper frame 1 and the lower frame 2 are buckled and fixed, the buckle 14 can extend into the groove of the buckle 14. Along the direction from the upper frame 1 to the lower frame 2, the cross-sectional shape of the buckle 14 is a barb type. The buckle 14 can make the upper frame 1 and the lower frame 2 fixed more firmly.

[0052] In an alternative embodiment, continue to refer to Figure 1 and Figure 2As shown, the upper frame 1 also includes a transverse plate 15, and the length extension direction of the transverse plate 15 is the same as the length extension direction of the first reinforcement 12 and / or the second reinforcement 22. The buckle 14 and the first snap-connecting structure 11 are respectively connected to the transverse plate 15. Optionally, the buckle 14 and the first snap-connecting structure 11 are respectively fixedly connected to the transverse plate 15. The buckle 14 and the first snap-connecting structure 11 are respectively located on opposite sides of the transverse plate 15 along the width direction of the upper frame 1. The buckle 14 corresponds to the buckle receiving groove 241 of the connecting member 24, and the first snap-connecting structure 11 corresponds to the photovoltaic module 4, which is beneficial for assembling the upper frame 1 and the lower frame 2 together in the later stage.

[0053] Optionally, the transverse plate 15, the buckle 14 and the first clamping structure 11 are an integrated structure, which can not only increase the stability of the upper frame 1, but also greatly shorten the assembly time cost of the upper frame 1, thereby improving the assembly efficiency.

EVA material introduces vinyl acetate monomer into the molecular chain, which can reduce the high crystallinity and improve toughness, impact resistance, filler solubility and heat sealing performance; POE (random copolymer elastomer of ethylene and high-carbon α-olefin); the molecular structure of POE material gives it excellent mechanical properties, rheological properties and UV resistance, and it also has good affinity with polyolefins, good low-temperature toughness, and high performance-price ratio; PVB (polyvinyl butyral) material, PVB material is soluble in methanol, ethanol, ketones, halogenated alkanes, and aromatic hydrocarbon solvents, and has good solubility with phthalates, sebacate plasticizers, as well as nitrocellulose, phenolic resin, epoxy resin, etc. It has high transparency, cold resistance, impact resistance, UV radiation resistance, and good adhesion to metals, glass, wood, ceramics, fiber products, etc. The battery cell can be PERC (Passivated Emitter Rear Cell), TOPCon (Tunnel Oxide Passivated Contact), HJT (Heterojunction with Intrinsic Thin-film), IBC (Interdigitated Back Contact), perovskite, etc.

[0056] In this embodiment, the protective frame 42 includes a bottom plate 421 and a side plate 422 connected to the bottom plate 421. An L-shaped structure can be formed between the bottom plate 421 and the side plate 422. The bottom wall of the periphery of the laminate 41 is placed on the bottom plate 421, and the side wall of the periphery of the laminate 41 is close to the side plate 422. The bottom plate 421 and the bottom wall of the periphery of the laminate 41 can be bonded with silicone 5, and the side wall of the periphery of the laminate 41 can also be bonded with silicone 5. It can be understood that the protective frame 42 only has a B side and a C side, but no A side. Since the protective frame 42 is a frame without an A side, the front cover plate 410 in the laminate 41 has no shielding material, so that the dirt on the surface of the laminate 41 can be smoothly separated from the component and discharged under the erosion of rainwater, avoiding water stains from being stored at the edge for a long time to soak the edge of the photovoltaic component 4, while increasing the light receiving area of ​​the laminate 41 to improve the photovoltaic efficiency.

[0057] During specific assembly, the protective frame 42 wrapped with the laminate 41 is directly installed in the accommodating space 3, wherein the bottom plate 421 is in direct contact with the second flexible pad 23, the side plate 422 is in contact with the side wall of the connector 24 in the lower frame 2, and the front cover plate 410 is bonded to the first flexible pad 13 on the side away from the first packaging film 411 and the top surface of the side plate 422. In the process of the photovoltaic module 4 bearing the load, since the first flexible pad 13, the first reinforcement 12 and the cross plate 15 are sequentially arranged above the edge of the laminate 41, and the bottom plate 421, the second flexible pad 23 and the second reinforcement 22 are sequentially designed below the edge of the laminate 41, the laminate 41 is greatly reduced from bursting due to stress concentration, and dust accumulation on the front cover plate 410 can also be avoided.

[0058] It can be seen from the above embodiments that the photovoltaic assembly 4 provided in this embodiment achieves at least the following beneficial effects:

[0059] The present embodiment provides a photovoltaic assembly 4, which is placed in the accommodating space 3 of the special-shaped frame 100 during installation, and the special-shaped frame 100 is the above-mentioned special-shaped frame 100; it includes a laminate 41 and a protective frame 42, and the protective frame 42 covers the circumferential edge of the laminate 41; the protective frame 42 includes a bottom plate 421 and a side plate 422 connected to the bottom plate 421, the bottom wall of the periphery of the laminate 41 is placed on the bottom plate 421, and the side wall of the periphery of the laminate 41 is close to the side plate 422. With the above-mentioned scheme, the protective frame 42 and the special-shaped frame 100 cooperate with each other, which can not only reduce the shear stress existing at the edge between the protective frame 42 and the special-shaped frame 100, but also because the protective frame 42A surface is directly eliminated, the light receiving area of ​​the laminate 41 can be increased, the photovoltaic efficiency is improved, and the accumulation of dust on the front of the laminate 41 is avoided.

[0060] Optionally, combined Figure 3 and Figure 5As shown, the protective frame 42 is made of galvanized aluminum-magnesium steel or aluminum alloy. Compared with steel, galvanized aluminum-magnesium steel and aluminum alloy have better elasticity, which is beneficial to prevent the frame from damaging the laminate 41 and can also reduce costs.

[0061] Optionally, along the direction from the upper frame 1 to the lower frame 2 , the height of the side plate 422 may range from 0.5 mm to 1.3 mm.

[0062] Specifically, combined Figure 3 and Figure 5 As shown, along the direction from the upper frame 1 to the lower frame 2, if the height of the side panel 422 is too high, it will be greater than the thickness of the laminate 41, and the top surface of the side panel 422 will not be flush with the surface of the laminate 41, which is not conducive to protecting the laminate 41 and can also increase the cost; if the height of the side panel 422 is too low, part of the edge of the laminate 41 is exposed to the outer surface of the side panel 422, which is also not conducive to protecting the laminate 41. Optionally, in this embodiment, the height range of the side panel 422 along the direction from the upper frame 1 to the lower frame 2 can be designed to be 0.5mm~1.3mm, so as to ensure that the front surface of the laminate 41 is flush with the top surface of the side panel 422 as much as possible, and the subsequent first flexible pad 13 can be directly bonded to the front surface of the laminate 41 and the top surface of the side panel 422, so as to more effectively protect the laminate 41 and reduce the cost. Specifically, along the direction from the upper frame 1 to the lower frame 2, the height of the side plate 422 can range from 0.5 mm, 0.7 mm, 0.9 mm, 1.1 mm or 1.3 mm.

[0063] It should be noted that: when the first flexible pad 13 includes a first sub-portion 131 and a second sub-portion 132 connected to the first sub-portion 131, the first sub-portion 131 is located on the side of the second sub-portion 132 close to the photovoltaic component 4, and the second flexible pad 23 includes a third sub-portion 231 and a fourth sub-portion 232 connected to the third sub-portion 231, and the third sub-portion 231 is located on the side of the fourth sub-portion 232 close to the photovoltaic component 4, along the width direction of the upper frame 1 and / or the lower frame 2, the width of the first sub-portion 131 and / or the third sub-portion 231 is equal to the width of the bottom plate 421, which can effectively fill the gap between the protective frame 42 and the special-shaped frame 100.

[0064] In an alternative embodiment, referring to Figure 6 As shown, Figure 6It is a structural schematic diagram of a partial protective frame in a photovoltaic module provided by the utility model; the protective frame 42 includes a long side protective frame 423 and a short side protective frame 424 connected to the long side protective frame 423, and both the head and tail ends of the long side protective frame 423 and the short side protective frame 424 are provided with a slope 425 with an inclination angle of 45 degrees, and the 45-degree slope 425 in the long side protective frame 423 and the 45-degree slope 425 in the short side protective frame 424 are spliced ​​together, and then laser welding technology is used to connect the two at the connection point, so that the connection between the long side protective frame 423 and the short side protective frame 424 is more stable, and since the long side protective frame 423 and the short side protective frame 424 are spliced ​​at the head and tail ends with the slope 425 with an inclination angle of 45 degrees, an aesthetic effect can also be achieved.

[0065] Reference Figure 1 , Figure 2 , Figure 3 , Figure 7-Figure 10 As shown, Figure 7 This is a front view of a photovoltaic system provided by the utility model; Figure 8 yes Figure 7 A partial enlarged view of the other direction at A in the middle; Fig. 9 It is a bottom view of a photovoltaic system provided by the utility model from another direction; Fig.10 yes Fig. 9 A local enlarged view of another direction at point B; this embodiment also provides a photovoltaic system, including a bracket (not shown in the figure), the above-mentioned photovoltaic component 4 and the above-mentioned special-shaped frame 100; the photovoltaic component 4 is placed in the accommodating space 3, wherein when a first flexible pad 13 is provided between the first reinforcement 12 and the photovoltaic component 4, the first flexible pad 13 is placed on the top surface of the photovoltaic component 4, and the bottom surface of the protective frame 42 is connected to the second flexible pad 23; the lower frame 2 is connected to the bracket.

[0066] Specifically, combined Figure 3 , Figure 7-Figure 10 As shown, the photovoltaic system includes a bracket, including the bracket, the photovoltaic module 4 and the special-shaped frame 100, the photovoltaic module 4 includes a laminate 41 and a protective frame 42, the protective frame 42 covers the circumferential edge of the laminate 41, wherein the protective frame 42 includes two long protective frames 423 and two short protective frames 424, the special-shaped frames 100 are respectively installed on the two long protective frames 423, the number of the special-shaped frames 100 can be two, the two special-shaped frames 100 can be arranged along the length direction of the long protective frames 423, the bracket is located below the photovoltaic module 4, and the bracket is assembled with the lower frame 2 in the special-shaped frame 100;

[0067] The photovoltaic component 4 is placed in the accommodating space 3 of the special-shaped frame 100, wherein when the first flexible pad 13 is arranged between the first reinforcement 12 and the photovoltaic component 4, the first flexible pad 13 is placed on the top surface of the laminate 41, and the first flexible pad 13 can be directly bonded to the top surface of the laminate 41, and the bottom surface of the protective frame 42 directly abuts against the top surface of the second flexible pad 23. Subsequently, when the laminate 41 is deformed upward or downward according to the thickness direction of the laminate 41, the shear stress of the laminate 41 can be reduced, thereby avoiding the risk of bursting of the laminate 41.

[0068] In an alternative embodiment, in combination Figure 2 , Figure 3 , Figure 7 and Figure 8 As shown, when the upper frame 1 includes a horizontal plate 15 and the lower frame 2 includes a connecting member 24, along the length direction of the special-shaped frame 100, the length of the horizontal plate 15 is equal to the length of the connecting member 24; when a first flexible pad 13 is arranged between the first reinforcement 12 and the photovoltaic component 4, and a second flexible pad 23 is arranged between the second reinforcement 22 and the photovoltaic component 4, along the length direction of the special-shaped frame 100, the lengths of the first reinforcement 12, the second reinforcement 22, the first flexible pad 13 and / or the second flexible pad 23 are equal; along the length direction of the special-shaped frame 100, the length of the first reinforcement 12 is greater than the length of the horizontal plate 15. Specifically, along the length direction of the special-shaped frame 100, the lengths of the first reinforcement 12 and the first flexible pad 13 introduced in the upper frame 1 and the second reinforcement 22 introduced in the lower frame 2 are consistent, the lengths of the horizontal plate 15 in the upper frame 1 and the connecting member 24 in the lower frame 2 are consistent, while the length of the first reinforcement 12 in the upper frame 1 is inconsistent with the length of the horizontal plate 15 in the upper frame 1. For example, along the length direction of the special-shaped frame 100, the length of the first reinforcement 12 in the upper frame 1 is greater than the length of the horizontal plate 15 in the upper frame 1. Along the length direction of the special-shaped frame 100, since the lengths of the first reinforcement 12, the second reinforcement 22, the first flexible pad 13 and the second flexible pad 23 are extended, the protective frame 42 can withstand the shear stress existing at the edge of the special-shaped frame 100, thereby reducing the incidence of bursting.

[0069] In an optional embodiment, along the length direction of the special-shaped frame 100, the length of the horizontal plate 15 and / or the connecting member 24 is L1, the length of the first reinforcement 12, the second reinforcement 22, the first flexible pad 13 and / or the second flexible pad 23 is L2, and L2-L1≥100mm.

[0070] Specifically, combined Figure 7 and Figure 8As shown, if along the length direction of the special-shaped frame 100, the length of the horizontal plate 15 and / or the connecting member 24 is L1, and the length of the first reinforcement 12, the second reinforcement 22, the first flexible pad 13 and / or the second flexible pad 23 is L2, if L2-L1 is too small, the length of the first reinforcement 12, the second reinforcement 22, the first flexible pad 13 and / or the second flexible pad 23 along the length direction of the special-shaped frame 100 is too short, and shear stress will exist at the edge position where the special-shaped frame 100 is connected to the protective frame 42, and the protective frame 42 cannot directly withstand the shear stress, thereby causing the bursting phenomenon. Optionally, in this embodiment, L2-L1≥100mm. Since the length of the first reinforcement 12, the first flexible pad 13 and the second reinforcement 22 along the length direction of the special-shaped frame 100 is extended, the shear stress at the edge position where the special-shaped frame 100 is connected to the protective frame 42 can be more effectively reduced, thereby more effectively reducing the bursting phenomenon of the laminate 41 due to the large shear stress.

[0071] In an alternative embodiment, in combination Figure 7 and Fig. 9 As shown, the length of the laminate 41 is L3, 3≤L3 / L2≤7.14. By adopting the above scheme, the length along the length direction of the special-shaped frame 100 is made so that the length of the first reinforcement 12, the second reinforcement 22, the first flexible pad 13 and / or the second flexible pad 23 is greater than the length of the cross plate 15 and the connecting member 24, and the maximum length of the first reinforcement 12, the second reinforcement 22, the first flexible pad 13 and / or the second flexible pad 23 is controlled to be less than the maximum length of the laminate 41, which can protect the laminate 41 while reducing costs.

[0072] Optionally, continue to refer to Figure 7 and Fig. 9 As shown, if the length of the special-shaped frame 100 is too long along the length extension direction of the photovoltaic component 4, the production cost of the special-shaped frame 100 will increase; if the length of the special-shaped frame 100 is too short, a large shear stress will be generated at the edge of the special-shaped frame 100, thereby causing a large shear stress to be generated inside the photovoltaic component 4; optionally, in this embodiment, the length range of the special-shaped frame 100 is designed to be 20cm-50cm along the length extension direction of the photovoltaic component 4, which can not only reduce the production cost of the special-shaped frame 100, but also help to reduce the large shear stress generated at the edge of the special-shaped frame 100, thereby reducing the large shear stress generated inside the photovoltaic component 4.
