Description

Technical Field

[0001] This application relates to the field of new energy technology, and in particular to a full-screen photovoltaic module and its frame. Background Technology

[0002] "Full-screen" is a broad definition in the mobile phone industry for a phone design with an ultra-high screen-to-body ratio. It means that when viewed from the front of the phone, only the screen is visible, and the four bezels are not visible. Full-screen designs aim for a screen-to-body ratio close to 100%. Applying the term "full-screen" to the photovoltaic module industry, it means that when viewed from the front (or top, the side responsible for light intake) of a photovoltaic module, only the front glass of the laminate is visible; the bezels of the photovoltaic module are not.

[0003] In existing photovoltaic (PV) modules, most frames have a relatively long A-side (the A-side being the portion of the frame that obscures the front of the laminate). PV modules using this frame are also known as framed PV modules. Due to the presence of the A-side, in outdoor environments with significant temperature variations, the frame can experience issues such as compression between itself and the glass of the PV module. This can lead to a reduction in the lifespan of the laminate, increase operating costs, and also affect the light-receiving area of ​​the laminate.

[0004] The frame of the photovoltaic module itself also has the following defects: the top A side of the photovoltaic module frame is in contact with the top edge of the laminate, and the A side is higher than the laminate. A gap is formed between the top edge of the laminate and the top A side of the frame. After the photovoltaic module frame is exposed to wind, sun and rain, dust particles will accumulate in the above gap, thus affecting the power generation efficiency of the photovoltaic module.

[0007] The support surface is used to connect with the edge of the bottom surface of the laminate, and at least one of the first surface and the second surface is used to connect with the side surface of the laminate to fix the laminate.

[0008] In one embodiment, the first surface is an inclined surface, and the second surface is a vertical surface;

[0012] And / or, the angle between the third surface and the plane containing the supporting surface is defined as β, where 20°≤β≤70°.

[0013] In one embodiment, α = β.

[0014] In one embodiment, the connecting portion has a fourth surface on the side away from the laminate, and the connecting portion also has a chamfered surface, with the two ends of the chamfered surface respectively connecting the fourth surface to the side of the first surface away from the second surface.

[0015] In one embodiment, a portion of the connecting portion protrudes from the base in the width direction.

[0016] In one embodiment, the connecting portion is integrally formed with the base portion.

[0017] This application also provides a full-screen photovoltaic module, including a laminate and a frame as described in any of the above embodiments, wherein the laminate has a bottom surface and side surfaces.

[0018] The edge of the bottom surface is connected to the supporting surface, and the side surface is connected to at least one of the first surface and the second surface.

[0019] In one embodiment, the first surface is an inclined surface, and the second surface is a vertical surface;

[0024] And / or, the surface of the first plate facing the battery cell is the same size as the surface of the second plate facing the battery cell.

[0025] Compared with existing technologies, the frame of the full-screen photovoltaic module provided in this application is used to fix the laminate in the full-screen photovoltaic module. The frame includes a base and a connecting part located on the upper side of the base. The supporting surface of the base is connected to the edge of the bottom surface of the laminate. At least one of the first and second surfaces of the connecting part is connected to the side surface of the laminate, so that the frame can fix the laminate only through the bottom and side surfaces of the laminate, and the frame does not contact the front surface of the laminate. When the frame and the laminate are assembled into a full-screen photovoltaic module, the front surface of the laminate is unobstructed by the frame, increasing the light-receiving area of ​​the laminate and thus improving the power generation efficiency. In addition, since the A-side of the frame is higher than the laminate in the prior art, rainwater and dust will accumulate between the front edge of the laminate and the top A-side of the frame; while the frame in this application can fix the laminate only through the bottom and side surfaces of the laminate, so the frame will not be higher than the laminate, and rainwater and dust will not accumulate on the front surface of the laminate, thus not affecting the light-receiving of the laminate, thereby improving the power generation efficiency.

The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0041] Please see Figures 1 to 6 This application provides a frame 10 for a full-screen photovoltaic module 1. The full-screen photovoltaic module 1 includes a laminate 20 and a frame 10. The frame 10 includes a base 110 and a connecting portion 120 disposed on the upper side of the base 110. The base 110 includes a supporting surface 111. The connecting portion 120 includes a first surface 121 and a second surface 122. Both the first surface 121 and the second surface 122 extend along the length and height directions of the base 110. In the height direction of the base 110, the second surface 122 is located between the first surface 121 and the supporting surface 111. One of the first surface 121 and the second surface 122 is a vertical surface, and the other is an inclined surface cut upward from one side near the supporting surface 111 to the other side. The supporting surface 111 is used to connect with the edge of the bottom surface 202 of the laminate 20, and at least one of the first surface 121 and the second surface 122 is used to connect with the side surface 201 of the laminate 20 to fix the laminate 20.

[0042] It is understandable that the frame 10 can fix the laminate 20 by connecting only the bottom surface 202 and the side surface 201 of the laminate 20. That is to say, the frame 10 does not contact the front (or top) surface of the laminate 20. When the frame 10 and the laminate 20 are assembled into a full-screen photovoltaic module 1, the front surface of the laminate 20 is not obstructed by the frame 10, which increases the light-receiving area of ​​the laminate 20 and thus improves the power generation efficiency.

[0043] Secondly, in the prior art, the A-side of the frame is higher than the laminate, forming a groove between the front edge of the laminate and the top of the frame. When it rains or snows, the groove is not conducive to drainage, and rainwater accumulates on the surface of the photovoltaic module, causing water to penetrate into the interior of the laminate, resulting in corrosion of the photovoltaic module. The groove also accumulates dust. However, in this application, the frame 10 can fix the laminate 20 only through the bottom surface 202 and the side surface 201 of the laminate 20. Therefore, the frame 10 will not be higher than the laminate 20, and rainwater and dust will not accumulate on the front surface of the laminate 20, thus not affecting the light transmission of the laminate 20, thereby improving the power generation efficiency.

[0044] It should be noted that the laminate 20 includes a first plate 210, a battery cell 220, and a second plate 230 connected in sequence. The frame 10 in this application can fix a rectangular laminate 20 (i.e., a laminate 20 where the sides of the first plate 210 and the second plate 230 are vertical surfaces, and the sides of the first plate 210 and the second plate 230 are on the same plane, the battery cell 220 is located between the first plate 210 and the second plate 230, and the side of the battery cell 220 does not protrude from this plane), or... By fixing irregularly shaped laminates 20 (including the following types: laminates 20 in which the sides of the first plate 210 and the second plate 230 are both vertical surfaces and not on the same plane; laminates 20 in which the sides of the first plate 210 and the second plate 230 are both inclined surfaces; laminates 20 in which one of the sides of the first plate 210 and the second plate 230 is inclined and the other is vertical), the applicability of the frame 10 can be improved, and this application does not limit it.

[0045] In one embodiment, such as Figure 1 As shown, in this embodiment, the first surface 121 of the frame 10 is a bevel, and the second surface 122 is a vertical surface. In this embodiment, refer to... Figure 2 The support surface 111 is connected to the edge of the bottom surface 202 of the laminate 20, and the inclined first surface 121 is connected to the side of the first plate 210 of the laminate 20, so as to increase the contact area between the frame 10 and the laminate 20.

[0046] In one embodiment, such as Figure 3 As shown, in this embodiment, the first surface 121 of the border 10 is a vertical surface, and the second surface 122 is a beveled surface. This improves the versatility of the border 10. For example, referring to… Figure 4 The supporting surface 111 is connected to the edge of the bottom surface 202 of the laminate 20, and the inclined second surface 122 is connected to the side surface of the second plate 230 of the laminate 20. In other embodiments, the inclined second surface 122 is simultaneously connected to the side surface of the first plate 210 and the side surface of the second plate 230 of the laminate 20, thereby further increasing the contact area between the frame 10 and the laminate 20. In another embodiment, refer to... Figure 5The inclined second surface 122 is connected to the side of the second plate 230 of the laminate 20, and the vertical first surface 121 is used to support the bottom surface 202 of the first plate 210 of the laminate 20. In this way, the contact area between the frame 10 and the laminate 20 is increased, so that the frame 10 can better support the laminate 20.

[0047] In one embodiment, such as Figure 6 As shown, the first surface 121 is an inclined surface, and the second surface 122 is a vertical surface. The connecting portion 120 also includes a third surface 123, which extends along the length and height directions of the base 110. The first surface 121, the second surface 122, the third surface 123, and the support surface 111 are connected in sequence, and the third surface 123 is inclined upward from the side connected to the support surface 111 towards the side connected to the second surface 122. At least one of the first surface 121, the second surface 122, and the third surface 123 is used to connect with the side surface 201 of the laminate 20. In this way, it is universal for the laminate 20, reduces the molds for manufacturing the frame 10, and thus saves the manufacturing cost of the frame 10.

[0048] Further, refer to Figure 7 The first surface 121 and the third surface 123 are both used to connect with the side surface 201 of the laminate 20. It should be noted that the first surface 121 is connected to the side surface of the first plate 210 of the laminate 20, and the third surface 123 is connected to the side surface of the second plate 230 of the laminate 20. In this way, the supporting area of ​​the frame 10 on the bottom surface 202 and the side surface 201 of the laminate 20 can be increased, making the connection between the frame 10 and the laminate 20 more stable. Moreover, the first surface 121 and the third surface 123 are both inclined surfaces, while the second surface 122 located between them is a vertical surface, making the connecting part 120 inclined and stepped. When the laminate 20 adapted to the frame 10 is connected to the frame 10, the laminate 20 and the frame 10 are embedded, and the laminate 20 is not easy to move in the frame 10, thereby improving the stability of the full-screen photovoltaic module 1.

[0049] In one embodiment, the angle between the plane containing the first surface 121 and the supporting surface 111 is α, where 20° ≤ α ≤ 70°. It is understood that, as... Figure 6As shown, the plane containing the first surface 121 and the supporting surface 111 also forms an obtuse angle complementary to α. The laminate 20 is positioned at the obtuse angle formed by the first surface 121 and the supporting surface 111. Furthermore, to ensure a tighter connection with the frame 10, the side surface 201 of the laminate 20 can be configured as a slope adapted to the first surface 121. When the first surface 121 is connected to the laminate 20 with the adapted slope, the slope of the first surface 121 and the laminate 20 can effectively block water flow. The cooperation between the slope of the first surface 121 and the laminate 20 allows the laminate 20 to be embedded in the frame 10, preventing it from shifting left or right, thus improving the stability of the full-screen photovoltaic module 1. Schematic, α can be 30°, 40°, 50°, 60°, or any other value within the range of 20°≤α≤70°.

[0050] In one embodiment, the angle between the plane containing the third surface 123 and the supporting surface 111 is defined as β, where 20° ≤ β ≤ 70°. It is understood that, as... Figure 6 As shown, the third surface 123 and the supporting surface 111 form an obtuse angle complementary to β. The laminate 20 is positioned at the obtuse angle formed by the third surface 123 and the supporting surface 111. Furthermore, to ensure a tighter connection with the frame 10, the side surface 201 of the laminate 20 can be configured as a bevel adapted to the third surface 123. When the third surface 123 is connected to the laminate 20 with the adapted bevel, the first surface 121 engages with the bevel of the laminate 20, allowing the laminate 20 to be embedded in the frame 10, making it less prone to lateral movement and thus improving the stability of the full-screen photovoltaic module 1. Schematic, β can be 30°, 40°, 50°, 60°, or any other value within the range of 20°≤β≤70°.

[0051] It is understood that the angle values ​​of α and β can be the same or different, and this application does not impose any restrictions on this.

[0052] In one embodiment, α = β. The first surface 121 and the third surface 123 have the same tilt angle, which makes the frame 10 more aesthetically pleasing. Furthermore, when the side surface 201 of the laminate 20 is provided with two inclined surfaces that are adapted to the first surface 121 and the third surface 123, the tilt angles of the first surface 121 and the third surface 123 are the same, which makes the manufacturing of the laminate 20 simpler and more aesthetically pleasing.

[0053] In one embodiment, the connecting portion 120 has a fourth surface 124 on the side away from the laminate 20, and the connecting portion 120 also has a chamfered surface 125. The two ends of the chamfered surface 125 are respectively connected to the fourth surface 124 and the side of the first surface 121 away from the second surface 122. It is understood that the chamfered surface 125 is rounded and curved. When it rains or snows and water flows on the surface of the laminate 20, the curved chamfered surface 125 has the effect of guiding the water flow away from the laminate 20. In this way, the residence time of the water flow on the laminate 20 can be reduced, and water flow can be prevented from penetrating into the interior of the laminate 20, thereby reducing the probability of water flow corroding the laminate 20. In addition, during the construction process such as the handling of the frame 10, the assembly process of the laminate 20 and the frame 10, and the installation process of the full-screen photovoltaic module 1, the chamfered surface 125 can prevent workers' arms from being cut during the above-mentioned construction processes, thereby improving the safety of use.

[0054] In one embodiment, a portion of the connecting portion 120 protrudes from the base 110 in the width direction. This increases the support area for the laminate 20 while reducing the volume of the base 110, thus reducing the material used in its manufacture and saving production costs.

[0055] Indicatively, the base 110 is a frame with a cavity, which increases the overall width of the frame 10, making the overall thickness of the frame 10 greater and less thin, thus increasing the supporting strength of the frame 10 and making it less prone to deformation. Corner brackets can also be added inside the cavity for the direct connection between the long frame 10 and the short frame 10.

[0056] In one embodiment, the connecting portion 120 and the base portion 110 are integrally formed. This simplifies the manufacturing process of the frame 10, improves production efficiency, and thus saves production costs. Illustratively, the frame 10 is formed by integral extrusion. Further, the frame 10 is made of aluminum alloy. In other embodiments, other materials, such as polymers, can be selected, as long as they meet certain rigidity requirements; this application does not impose any limitations on this.

[0057] This application also provides a full-screen photovoltaic module 1, for reference. Figure 8 The system includes a laminate 20 and a frame 10 as described in any of the above embodiments. The laminate 20 has a bottom surface 202 and a side surface 201. The edge of the bottom surface 202 of the laminate 20 is connected to the support surface 111, and the side surface 201 is connected to at least one of the first surface 121 and the second surface 122. The frame 10 only connects the bottom surface 202 and the side surface 201 of the laminate and does not obstruct the top surface (i.e., the front surface) of the laminate 20. In this way, the light-receiving area of ​​the laminate 20 is increased, thereby improving the power generation efficiency of the full-screen photovoltaic module 1.

[0058] Secondly, since the frame 10 of the full-screen photovoltaic module 1 in this application does not have an A-side, no groove is formed between the front edge of the laminate 20 and the top of the frame 10. When it rains or snows, water can flow directly down from the edge of the laminate 20 and will not accumulate on the surface of the laminate 20, thus preventing water from penetrating into the interior of the laminate 20 and causing corrosion. In this way, not only can the service life of the full-screen photovoltaic module 1 be extended, but dust will also not accumulate on the front of the laminate 20, which will not affect the light transmission of the laminate 20, thereby improving the power generation efficiency of the full-screen photovoltaic module 1.

[0059] Furthermore, the full-screen photovoltaic module 1 in this application does not have an A-side that obstructs the shading laminate 20; the entire front is the first panel 210. This results in a higher degree of integration and a more aesthetically pleasing appearance. Illustratively, the first panel 210 is made of glass, which provides high light transmittance and does not affect the light intake of the solar cells 220, thereby improving the power generation efficiency of the full-screen photovoltaic module 1.

[0060] In this embodiment, the laminate 20 and the frame 10 can be connected by using hot melt adhesive and room temperature vulcanizing adhesive, or by using silicone. This application does not limit the connection in this regard.

[0061] In one embodiment, the side surface 201 of the laminate 20 is connected to both the first surface 121 and the third surface 123. This increases the supporting area of ​​the frame 10 on the bottom surface 202 and the side surface 201 of the laminate 20, making the connection between the frame 10 and the laminate 20 more stable, thereby improving the stability of the full-screen photovoltaic module 1.

[0062] In one embodiment, the laminate 20 includes a first plate 210, a battery cell 220, and a second plate 230 connected in sequence. The side of the first plate 210 of the laminate 20 is an inclined surface adapted to the first surface 121 of the frame 10, and the side of the second plate 230 is an inclined surface adapted to the third surface 123 of the frame 10. This simplifies the manufacturing of the laminate 20 and improves its production efficiency.

[0063] In one embodiment, the surface of the first plate 210 facing the solar cell 220 is the same size as the surface of the second plate 230 facing the solar cell 220. This makes the structure of the laminate 20 more compact and aesthetically pleasing, and also makes the frame 10 that is adapted to the laminate 20 more aesthetically pleasing, resulting in a more attractive full-screen photovoltaic module 1 composed of the laminate 20 and the frame 10.

[0064] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0065] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
