Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic components, in particular to a photovoltaic component. Background Art

[0002] In related technologies, the four sides of the frame of a photovoltaic module usually have an A-side, that is, the top of the frame, and the A-side of the frame will be higher than the front glass. After the photovoltaic module is installed outdoors, although it is washed by rain, dust, fallen leaves and other debris will still accumulate on the inner side of the A-side of the photovoltaic module, blocking the surface of the photovoltaic module, thereby affecting the power generation of the photovoltaic module.

[0003] Therefore, some photovoltaic modules do not have an A-side on all four sides of the frame, and the airborne reliability cannot meet the requirements; some photovoltaic modules have the A-side removed from part of the frame, but the frame without the A-side is still higher than the front glass, and the problem of debris accumulation still exists. Utility Model Content

[0004] In view of this, the present invention provides a photovoltaic module to solve the problems of debris accumulation and poor stability on the photovoltaic module.

[0005] The utility model provides a photovoltaic component, comprising: a laminate, wherein the laminate has a first side surface and a second side surface arranged adjacent to each other; a first frame, wherein the first frame comprises a first supporting portion and a second supporting portion connected to each other, the first supporting portion is supported on the first side surface and is lower than the top surface of the laminate, and the second supporting portion is supported on the bottom surface of the laminate; a second frame, wherein the second frame is connected to the first frame and comprises a third supporting portion, a fourth supporting portion and a limiting portion, the fourth supporting portion and the limiting portion are both connected to the third supporting portion, the third supporting portion is supported on the second side surface, the fourth supporting portion is supported on the bottom surface of the laminate, and the limiting portion is crimped to the top surface of the laminate; wherein the first side surface comprises a first inclined section, and the first inclined section is connected to the top surface of the laminate.

[0006] Beneficial effect: Since the top of the first support portion is lower than the top surface of the laminate, when debris on the laminate moves toward the first support portion, the first support portion will not interfere with the above-mentioned debris, and thus the debris will not accumulate on the top surface of the laminate. Even if the debris accumulates on the top of the first support portion, it will not affect the power generation efficiency of the laminate. By setting the first inclined section, the first inclined section can guide the debris on the laminate, which is conducive to rainwater or natural wind washing away the debris on the laminate. The surface of the photovoltaic module is less likely to accumulate dust, leaves and other debris, effectively removing the debris on the surface of the photovoltaic module, and greatly improving the anti-dust performance of the photovoltaic module. In addition, the first inclined section increases the horizontal distance between the first support portion and the top surface of the laminate. Even if there is debris accumulated on the top of the first support portion, the lighting area of the laminate is less affected, thereby ensuring the power generation performance of the photovoltaic module when operating outdoors, and the photovoltaic module can operate outdoors for a long time. By setting a limiting portion in cooperation with the fourth supporting portion, the laminate is clamped from opposite sides in the thickness direction of the laminate, which can prevent the laminate from shaking relative to the frame in its thickness direction, and limit the relative position of the laminate and the frame in its thickness direction. The airborne reliability between the frame and the laminate is high.

[0007] In an optional embodiment, the height difference between the top surface of the laminate and the top end of the first support portion is in the range of 0.5 mm to 1.5 mm.

[0008] Beneficial effects: It can ensure that the area corresponding to the top of the first support part and the side of the laminate is larger, and the first frame has a better limiting effect on the laminate, which is beneficial to ensure the relative position between the frame and the laminate, thereby improving the stability of the photovoltaic module, and can leave enough space between the top of the first support part and the top surface of the laminate, so that debris on the top surface of the laminate can be separated from the laminate from the side where the first frame is located, thereby improving the cleaning efficiency of the laminate.

[0009] In an optional embodiment, the lower end of the first inclined section is lower than the top end of the first supporting portion.

[0010] Beneficial effect: The first inclined section has a large height, which can effectively guide the debris on the top surface of the laminate to slide downward, avoiding the debris on the top surface of the laminate from encountering obstacles and accumulating during movement, thereby improving cleaning efficiency.

[0011] In an optional embodiment, the first inclined section is configured to be arc-shaped.

[0012] Beneficial effect: The first inclined section not only guides debris on the laminate, but also enables an arc-shaped transition between the top surface and the first side surface of the laminate. That is, the transition between the first inclined section and the top surface of the laminate is smooth, and the transition between the first inclined section and the rest of the side surface of the laminate is smooth. The surface of the laminate is evenly stressed, which helps prevent local pressure concentration and reduce the probability of damage to the laminate.

[0013] In an optional embodiment, the first side surface further includes a second inclined section, which is connected to the bottom surface of the laminate and is inclined relative to the bottom surface of the laminate, and the height of the second inclined section gradually increases towards the first frame.

[0014] Beneficial effect: The distance between the second inclined section and the first frame is increased, and more sealant is stored between the second inclined section and the first frame, which is beneficial to reducing the amount of glue on the back of the laminate, ensuring that the bottom surface of the laminate is beautiful and clean, and reducing costs.

[0015] In an optional embodiment, a side surface of the first supporting portion facing the laminate is adapted to a shape of the first side surface.

[0016] Beneficial effect: The gap between the side surface of the first supporting portion facing the laminate and the entire first side surface is reduced, which can reduce the amount of sealant required between the first frame and the laminate and reduce costs.

[0017] In an optional embodiment, the laminate includes: a front glass, the front glass is provided with a first inclined section, the first inclined section is configured to be arc-shaped, and the radius of the first inclined section is smaller than the thickness of the front glass; a back glass, the back glass is located below the front glass, the back glass is provided with a second inclined section, the second inclined section is configured to be arc-shaped, and the radius of the second inclined section is smaller than the thickness of the back glass.

[0018] Beneficial effects: It can avoid the appearance of curved areas on the lower surface of the front glass, ensuring a close fit between the lower surface of the front glass and the adhesive film, and it can avoid the appearance of curved areas on the upper surface of the back glass, ensuring a close fit between the upper surface of the back glass and the adhesive film, which is conducive to ensuring a smooth transition of the first side and high structural strength of the laminate.

[0019] In an optional embodiment, a glue overflow groove is provided on the upper surface of the second supporting portion, and the glue overflow groove is adjacent to an end of the second supporting portion away from the first supporting portion.

[0020] Beneficial effects: On the one hand, it can reduce the amount of glue overflow on the bottom surface of the laminate to ensure that the bottom surface of the laminate is beautiful and clean. On the other hand, it can ensure that the sealant is effectively filled between the second supporting part and the bottom surface of the laminate. The connection area between the second supporting part and the bottom surface of the laminate is large, which is conducive to improving the connection strength between the second supporting part and the bottom surface of the laminate.

[0021] In an optional embodiment, the glue overflow groove has a first groove wall and a second groove wall, and the first groove wall is closer to the first support part than the second groove wall; the first groove wall is inclined relative to the bottom surface of the laminate, and the height of the first groove wall gradually increases toward the first support part; the second groove wall is provided with a glue limiting protrusion, and the upper surface of the glue limiting protrusion is flush with the upper surface of the second support part.

[0022] Beneficial effect: the first groove wall is conducive to the sealant flowing into the overflow groove, and the sealant limiting protrusion is more conducive to limiting the sealant in the overflow groove from flowing out of the overflow groove.

[0023] In an optional embodiment, the length of the first frame is smaller than the length of the second frame.

[0024] Beneficial Effects: The longer length of the first frame increases the contact area between the second frame's stopper and the laminate, helping to ensure the vertical stability of the relative positions of the frame and laminate, thereby improving the airborne reliability of the photovoltaic module. Furthermore, the shorter length of the first frame does not affect dust removal on the photovoltaic module's surface, and can also reduce the cost and weight of the photovoltaic module.

Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0037] The following combination Figures 1 to 5 , describing the embodiments of the present utility model.

[0038] According to an embodiment of the present invention, a photovoltaic assembly 1 is provided. The photovoltaic assembly 1 includes a laminate 100 , a first frame 210 and a second frame 220 .

[0039] The laminate 100 has a first side surface 103 and a second side surface 104 disposed adjacent to each other. The first frame 210 includes a first support portion 211 and a second support portion 212. The first support portion 211 is connected to the second support portion 212. The first support portion 211 is supported on the first side surface 103. The top end of the first support portion 211 is lower than the top surface of the laminate 100. The second support portion 212 is supported on the bottom surface of the laminate 100. The bottom end of the first support portion 211 can be connected to the second support portion 212.

[0040] The first frame 210 is connected to the second frame 220. The second frame 220 includes a third supporting portion 221, a fourth supporting portion 222, and a limiting portion 223. The third supporting portion 221 is supported on the second side surface 104. The fourth supporting portion 222 is connected to the third supporting portion 221. The fourth supporting portion 222 is supported on the bottom surface of the laminate 100. The limiting portion 223 is connected to the third supporting portion 221. The limiting portion 223 is pressed against the top surface of the laminate 100. The top end of the third supporting portion 221 is connected to the limiting portion 223, and the bottom end of the third supporting portion 221 is connected to the fourth supporting portion 222.

[0041] Specifically, there can be two first frames 210, which are arranged opposite to each other, and there can be two second frames 220, which are arranged opposite to each other. The first frames 210 and the second frames 220 are arranged alternately along the circumference of the laminate 100, and adjacent first frames 210 and second frames 220 are connected.

[0042] For example, the adjacent first frame 210 and second frame 220 are connected by corner brackets, the laminate 100 and the first frame 210 are bonded by sealant 300, and the laminate 100 and the second frame 220 are bonded by sealant 300, wherein the sealant 300 can be made of silicone material.

[0043] By arranging two first frames 210 and two second frames 220 alternately along the circumference of the laminate 100, it is possible to ensure that all circumferential side surfaces of the laminate 100 are connected to the frames (i.e., the first frames 210 and the second frames 220), thereby ensuring that the relative position between the frames and the laminate 100 is stable.

[0044] By setting the third support part 221 to cooperate with the first support part 211, the two first support parts 211 and the two third support parts 221 surround the laminate 100 along the circumference of the laminate 100, the contact area between the frame and the side of the laminate 100 is larger, and the laminate 100 is fixed in two directions. The positioning effect between the frame and the laminate 100 is better, and the frame and the laminate 100 are effectively prevented from separating.

[0045] By providing the fourth supporting portion 222 and the second supporting portion 212 to jointly support the laminate 100 , the contact area between the frame and the bottom surface of the laminate 100 is larger, which is beneficial to increasing the supporting effect of the frame on the laminate 100 .

[0046] In addition, by setting a limiting portion 223 to cooperate with the fourth supporting portion 222, the laminate 100 is clamped from opposite sides in the thickness direction of the laminate 100, which can prevent the laminate 100 from shaking relative to the frame in its thickness direction, and limit the relative position of the laminate 100 and the frame in its thickness direction, and the airborne reliability between the frame and the laminate 100 is high.

[0047] The first side surface 103 includes a first inclined section 101 , which is connected to the top surface of the laminate 100 and is inclined relative to the top surface of the laminate 100 . The height of the first inclined section 101 gradually decreases toward the first frame 210 .

[0048] Since the top of the first support part 211 is lower than the top surface of the laminate 100, when debris such as fallen leaves and dust on the laminate 100 moves toward the first support part 211, the first support part 211 will not interfere with the above-mentioned debris, and the debris will not accumulate on the top surface of the laminate 100. Even if the debris accumulates on the top of the first support part 211, it will not affect the power generation efficiency of the laminate 100.

[0049] By setting the first inclined section 101, the first inclined section 101 can guide the debris on the laminate 100, which is conducive to rainwater or natural wind to wash away the debris on the laminate 100. The surface of the photovoltaic module 1 is less likely to accumulate dust, leaves and other debris, and the debris on the surface of the photovoltaic module 1 is effectively removed, so that the anti-dust accumulation performance of the photovoltaic module 1 is greatly improved. In addition, the first inclined section 101 increases the horizontal distance between the first support part 211 and the top surface of the laminate 100. Even if there is debris accumulated on the top of the first support part 211, the lighting area of the laminate 100 is less affected, thereby ensuring the power generation performance of the photovoltaic module 1 when operating outdoors, and the photovoltaic module 1 can operate outdoors for a long time.

[0050] like Figure 2 As shown, in this embodiment, the height difference D between the top surface of the laminate 100 and the top of the first support portion 211 is in the range of 0.5 mm to 1.5 mm, for example, the height difference D between the top surface of the laminate 100 and the top of the first support portion 211 is 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm or 1.5 mm.

[0051] If the height difference D between the top surface of the laminate 100 and the top of the first support part 211 is less than 0.5 mm, the height difference between the top surface of the laminate 100 and the top of the first support part 211 is too small, and the top of the first support part 211 is relatively close to the top surface of the laminate 100. There may be glue overflow at the top of the first support part 211, which may easily cause debris on the laminate 100 to accumulate at the transition between the top surface of the laminate 100 and the top of the first support part 211, affecting the cleaning effect.

[0052] If the height difference D between the top surface of the laminate 100 and the top of the first support part 211 is greater than 1.5 mm, the height difference between the top surface of the laminate 100 and the top of the first support part 211 is too large, the area corresponding to the side of the first support part 211 and the laminate 100 is small, the first frame 210 has a poor limiting effect on the laminate 100, and there is less sealant 300 between the first frame 210 and the laminate 100, and the stability between the frame and the laminate 100 is poor, which affects the mechanical stability of the assembly.

[0053] By setting the height difference D between the top surface of the laminate 100 and the top of the first support part 211 to 0.5mm~1.5mm, it can be ensured that the area corresponding to the side of the first support part 211 and the laminate 100 is larger, the first frame 210 has a better limiting effect on the laminate 100, and there is more sealant 300 between the first frame 210 and the laminate 100, which is beneficial to ensure the relative position between the frame and the laminate 100, thereby improving the stability of the photovoltaic module 1, and can leave enough space between the top of the first support part 211 and the top surface of the laminate 100, so that the debris on the top surface of the laminate 100 can be separated from the laminate 100 from the side where the first frame 210 is located, thereby improving the cleaning efficiency of the laminate 100.

[0054] like Figure 2 As shown, in this embodiment, the lower end of the first inclined section 101 is lower than the top end of the first supporting portion 211. In this way, the first inclined section 101 has a greater height, which can effectively guide the debris on the top surface of the laminate 100 to slide downward, preventing the debris from encountering obstacles and accumulating on the top surface of the laminate 100 during movement, thereby improving cleaning efficiency.

[0055] like Figure 2 and Figure 4 As shown, in this embodiment, the first inclined section 101 is constructed in an arc shape. In this way, the first inclined section 101 not only guides debris on the laminate 100, but also facilitates grinding and shaping, reduces processing difficulty, improves production efficiency, and can achieve an arc-shaped transition between the top surface of the laminate 100 and the first side surface 103. In other words, the transition between the first inclined section 101 and the top surface of the laminate 100 is smooth, and the transition between the first inclined section 101 and the rest of the side surface of the laminate 100 is smooth. The surface of the laminate 100 is subjected to uniform force, which helps prevent local pressure concentration and reduces the probability of damage to the laminate 100.

[0056] like Figure 2 As shown, in this embodiment, the first side surface 103 also includes a second inclined section 102, which is connected to the bottom surface of the laminate 100 and is inclined relative to the bottom surface of the laminate 100, and the height of the second inclined section 102 gradually increases toward the first frame 210.

[0057] For example, the first side surface 103 further includes a planar segment connected between the first inclined segment 101 and the second inclined segment 102 , and the planar segment is perpendicular to the bottom surface and the top surface of the laminate 100 .

[0058] In this way, an arc-shaped transition can be made between the bottom surface of the laminate 100 and the first side surface 103, that is, the transition between the second inclined section 102 and the bottom surface of the laminate 100 is smooth, and the transition between the second inclined section 102 and the plane section is smooth. The surface of the laminate 100 is evenly stressed, which is beneficial to prevent local pressure concentration and reduce the probability of damage to the laminate 100.

[0059] In addition, by providing the second inclined section 102, the upper and lower shapes of the first side surface 103 are ensured to be roughly the same, and the appearance of the laminate 100 is more beautiful. Moreover, the distance between the second inclined section 102 and the first frame 210 is increased, and the amount of sealant 300 stored between the second inclined section 102 and the first frame 210 is greater, which is beneficial to reducing the amount of glue on the back of the laminate 100, thereby ensuring that the bottom surface of the laminate 100 is beautiful and clean, and reducing costs.

[0060] like Figure 2-Figure 4 As shown, in this embodiment, the side of the first supporting portion 211 facing the laminate 100 is adapted to the shape of the first side 103. For example, if the first inclined section 101 and the second inclined section 102 are both arc-shaped structures, the side of the first supporting portion 211 facing the laminate 100 can be configured as an arc-shaped structure to fit the first inclined section 101 and the second inclined section 102 of the laminate 100.

[0061] In this way, the gap between the side surface of the first support portion 211 facing the laminate 100 and the first side surface 103 is reduced, which can reduce the amount of sealant 300 required between the first frame 210 and the laminate 100 and reduce costs.

[0062] like Figure 2 and Figure 4 As shown, in this embodiment, the laminate 100 includes a front glass 110 and a back glass 120, the front glass 110 is provided with a first inclined section 101, the first inclined section 101 is configured to be arc-shaped, and the radius R1 of the first inclined section 101 is smaller than the thickness of the front glass 110, the back glass 120 is located below the front glass 110, and the back glass 120 is provided with a second inclined section 102, the second inclined section 102 is configured to be arc-shaped, and the radius R2 of the second inclined section 102 is smaller than the thickness of the back glass 120.

[0063] For example, the laminate 100 further includes an adhesive film 130 and a battery cell 140 , which are located between the front glass 110 and the back glass 120 . The laminate 100 is formed by laminating the front glass 110 , the adhesive film 130 , the battery cell 140 and the back glass 120 .

[0064] In this way, the appearance of a curved area on the lower surface of the front glass 110 can be avoided, ensuring a tight fit between the lower surface of the front glass 110 and the adhesive film 130. The appearance of a curved area on the upper surface of the back glass 120 can also be avoided, ensuring a tight fit between the upper surface of the back glass 120 and the adhesive film 130. This is conducive to ensuring a smooth transition of the first side surface 103 and high structural strength of the laminate 100.

[0065] like Figure 2 and Figure 3 As shown, in this embodiment, a glue overflow groove 213 is provided on the upper surface of the second support portion 212. The glue overflow groove 213 is adjacent to the end of the second support portion 212 away from the first support portion 211. This can, on the one hand, reduce the amount of glue overflow from the bottom surface of the laminate 100, ensuring that the bottom surface of the laminate 100 is beautiful and clean. On the other hand, it can ensure that the sealant 300 is effectively filled between the second support portion 212 and the bottom surface of the laminate 100. The connection area between the second support portion 212 and the bottom surface of the laminate 100 is large, which is conducive to improving the connection strength between the second support portion 212 and the bottom surface of the laminate 100.

[0066] For example, the overflow glue groove 213 has a first groove wall 214 and a second groove wall 215. The first groove wall 214 is closer to the first support part 211 than the second groove wall 215. The first groove wall 214 is inclined relative to the bottom surface of the laminate 100. The height of the first groove wall 214 gradually increases toward the first support part 211, which is conducive to the sealant 300 flowing into the overflow glue groove 213. The second groove wall 215 is provided with a glue limiting protrusion 216. The upper surface of the glue limiting protrusion 216 is flush with the upper surface of the second support part 212, which is more conducive to limiting the sealant 300 in the overflow glue groove 213 from flowing out of the overflow glue groove 213.

[0067] like Figure 1 As shown, in this embodiment, the length of the first frame 210 is shorter than the length of the second frame 220. This increases the contact area between the stopper 223 of the second frame 220 and the laminate 100, which helps ensure the vertical stability of the relative position of the frame and the laminate 100, thereby improving the airborne reliability of the photovoltaic module 1. Furthermore, the shorter length of the first frame 210 does not affect the dust removal of the photovoltaic module 1, and can also reduce the cost and weight of the photovoltaic module 1.

[0068] Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations shall fall within the scope defined by the appended claims.
