Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic panels, and in particular to a photovoltaic frame and a photovoltaic module. Background Art

[0002] With the development of the photovoltaic industry, competition in the power generation of photovoltaic modules is becoming increasingly fierce. Several photovoltaic modules, either horizontal or with a small angle to the horizontal, are currently available on the market. Because the frame sidewalls on the light-entering side of the laminate are typically equipped with glue overflow grooves, the frame structure protrudes a considerable distance from the light-entering side of the laminate, forming a high step surface. When photovoltaic modules are installed horizontally or at a small angle, the high step surface formed by the protruding frame prevents rainwater from draining completely. The mirror surface formed by the rainwater reflects some of the sunlight that hits the laminate. Furthermore, rainwater absorbs dust from the air. After evaporation, the dust adheres to the front glass surface of the photovoltaic module, obstructing the module and seriously affecting its power generation. Utility Model Content

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

[0030] Reference Figure 1 、 Figure 2 、 Figure 3 as well as Figure 4 As shown, an embodiment of the present application discloses a photovoltaic frame, including a frame strip 100; the frame strip 100 is suitable for being arranged along the periphery of a photovoltaic laminate 101; a card slot 102 is provided on the frame strip 100, and the edge of the photovoltaic laminate 101 is embedded in the card slot 102; the card slot 102 has a first clamping side wall 103 and a second clamping side wall 104 and a middle connecting side wall 105; the inner surface of the first clamping side wall 103 is parallel to the light-incident side of the photovoltaic laminate 101, the inner surface of the second clamping side wall 104 is in contact with the backlight side of the photovoltaic laminate 101, and a glue storage groove 106 is provided on the inner surface of the second clamping side wall 104 and / or the middle connecting side wall 105.

[0031] It should be noted that the inner surface of the first clamping side wall 103 , the inner surface of the second clamping side wall 104 and the inner surface of the middle connecting side wall 105 all refer to surfaces close to the photovoltaic laminate 101 .

[0032] It should be noted that the border strip 100 of the embodiment of the present application can be enclosed into a rectangle or other shapes. The shape of the border strip 100 is specifically determined according to the planar shape of the photovoltaic laminate 101 structure. Those skilled in the art can set it as needed. The border strip 100 of the embodiment of the present application has a card slot 102, and the card slot 102 has a first clamping side wall 103 and a second clamping side wall 104 and a middle connecting side wall 105. Among them, the first clamping side wall 103 and the second clamping side wall 104 and the middle connecting side wall 105 can form a U-shaped card slot 102, and the distance between the first clamping side wall 103 and the second clamping side wall 104 is slightly greater than or equal to the thickness of the photovoltaic laminate 101.

[0033] It should be noted that an adhesive layer is provided within the slot 102. In this embodiment of the present application, adhesive storage tanks 106 are provided on the second clamping sidewall 104 and the central connecting sidewall 105 to store the adhesive in the adhesive layer, thereby preventing the adhesive from being squeezed out under the pressure of the photovoltaic laminate 101, thereby reducing the connection strength. This embodiment of the present application avoids providing the adhesive storage tank 106 on the first clamping sidewall 103, resulting in a thinner first clamping sidewall 103. This reduces the accumulation of rainwater on the surface of the photovoltaic laminate 101 when the photovoltaic laminate 101 is horizontal or at a low inclination angle.

[0034] The embodiment of the present application discloses a photovoltaic frame, including a frame strip 100; the frame strip 100 is arranged along the periphery of a photovoltaic laminate 101; the frame strip 100 has a slot 102, and the edge of the photovoltaic laminate 101 is inserted into the slot 102; the embodiment of the present application can achieve reliable installation of the photovoltaic laminate 101 by arranging the frame strip 100 around the photovoltaic laminate 101 and inserting the photovoltaic laminate 101 into the slot 102. The slot 102 of the embodiment of the present application has a first clamping side wall 103, a second clamping side wall 104, and a middle connecting side wall 105; the first clamping side wall 103 is parallel to the light-incident side of the photovoltaic laminate 101, the second clamping side wall 104 is in contact with the backlight side of the photovoltaic laminate 101, and a glue storage groove 106 is provided on the second clamping side wall 104 and / or the middle connecting side wall 105. By disposing the glue storage tank 106 on the first clamping sidewall 103, the embodiment of the present application can effectively reduce the thickness of the first clamping sidewall 103, thereby preventing the first clamping sidewall 103 from protruding from the surface of the photovoltaic laminate 101. When the photovoltaic module is installed horizontally or at a small angle, the frame strip 100 of the embodiment of the present application effectively alleviates the problem of rainwater not being able to drain completely, prevents rainwater from reflecting sunlight, and reduces dust adhesion. Therefore, the embodiment of the present application can effectively increase the power generation efficiency of the photovoltaic module.

[0035] Reference Figure 3 、 Figure 4 、 Figure 5 as well as Figure 6 As shown, as an optional embodiment, the middle connecting side wall 105 connects the first clamping side wall 103 and the second clamping side wall 104; the clamping groove 102 is a U-shaped groove.

[0036] It should be noted that the card slot 102 may also be configured to have other shapes, and those skilled in the art may select the shapes according to their needs.

[0037] Reference Figure 3 and Figure 4 As shown, as an optional embodiment, a guide portion is provided at one end of the first clamping side wall 103 away from the middle connecting side wall 105, and the thickness of the guide portion gradually decreases in the direction away from the middle connecting side wall 105, and a guide slope 107 is located on the guide portion. The guide slope 107 is suitable for smoothly connecting the outer surface of the first clamping side wall 103 and the light incident surface of the photovoltaic lamination 101, and is used to prevent the first clamping side wall 103 from forming a step surface on the light incident surface of the photovoltaic lamination 101. The angle between the guide slope 107 and the light incident surface of the photovoltaic lamination 101 is 5-60°. Exemplarily, the angle between the guide slope 107 and the light incident surface of the photovoltaic lamination 101 is 5°, or 10°. Those skilled in the art can make settings as needed.

[0038] It should be noted that, in the embodiment of the present application, a guide slope 107 is provided on the side of the first side wall away from the middle connecting side wall 105. The guide slope 107 can drain rainwater on the surface of the photovoltaic laminate 101, further reducing the accumulation of rainwater, avoiding the adsorption of dust and reflection of sunlight by rainwater, thereby improving the power generation capacity of the photovoltaic module.

[0039] Furthermore, the thickness of the first clamping sidewall 103 in the embodiment of the present application is 1.5 mm to 2.5 mm, preferably 1.5 mm. The thin thickness of the first clamping sidewall 103 in the embodiment of the present application reduces its ability to block rainwater, facilitating the rapid drainage of rainwater from the surface of the photovoltaic laminate 101, reducing rainwater accumulation, and preventing rainwater from adsorbing dust and reflecting sunlight, thereby increasing the power generation efficiency of the photovoltaic module.

[0040] As an optional embodiment, a strip guiding structure is provided on the guiding slope 107 , and the strip guiding structures are spaced apart along the extending direction of the frame strip 100 , and the extending direction of the strip guiding structures is perpendicular to the extending direction of the frame strip 100 .

[0041] Furthermore, the embodiment of the present application is provided with a strip guide structure on the guide slope 107, which can drain rainwater on the surface of the photovoltaic laminate 101, further reducing rainwater accumulation, avoiding rainwater adsorption of dust and reflection of sunlight, thereby further improving the power generation capacity of the photovoltaic module.

[0042] It should be noted that the strip-shaped guide structure can be a guide groove or other drainage strip. Those skilled in the art can configure this as needed, and no specific limitation is imposed herein. By aligning the strip-shaped guide structure perpendicularly to the frame strip 100, the strip-shaped guide structure can guide rainwater on the surface of the photovoltaic laminate 101 to the outside of the photovoltaic module, allowing the rainwater to drain.

[0043] Reference Figure 1 and Figure 2 As shown, as an optional embodiment, the inner wall of the slot 102 has an adhesive layer connected to the photovoltaic laminate 101; the glue storage groove 106 extends in the same direction as the frame strip 100, and the glue storage groove 106 opens toward the photovoltaic laminate 101. It should be noted that the adhesive layer is not shown in the figure. Regarding the formation of the adhesive layer, the slot 102 can be filled with adhesive. When the edge of the photovoltaic laminate 101 is inserted into the slot 102, the edge of the photovoltaic laminate 101 is squeezed, forming an adhesive layer between the edge of the photovoltaic laminate 101 and the slot 102.

[0044] Furthermore, the embodiment of the present application discloses a specific setting direction of the glue storage tank 106. Through the setting of the glue storage tank 106, the adhesive layer can be continuously set along the extension direction of the glue storage tank 106, effectively improving the bonding strength of the adhesive layer and achieving reliable fixation of the photovoltaic laminate 101.

[0045] It should be noted that the specific material of the adhesive layer can be selected by those skilled in the art as needed.

[0046] Reference Figure 3 and Figure 4 As shown, as an optional embodiment, the frame strip 100 further includes a support portion, which is fixedly connected to the second clamping side wall 104. The bottom of the support portion extends out to form a connecting bottom plate 109, which is used to connect to an external structure.

[0047] The supporting portion has a supporting side wall 108 ; the supporting side wall 108 extends in the direction of the middle connecting side wall 105 , and the connecting bottom plate 109 is disposed at one end of the supporting side wall 108 away from the first clamping side wall 103 .

[0048] It should be noted that the first clamping side wall 103 is the A side of the frame; the supporting side wall 108 and the middle connecting side wall 105 are the B side of the frame; and the connecting bottom plate 109 is the C side of the frame.

[0049] Reference Figure 3 and Figure 4As shown, as an optional embodiment, the connecting base plate 109 extends toward the photovoltaic laminate 101 on a side away from the supporting side wall 108; the overlapping area between the connecting base plate 109 and the photovoltaic laminate 101 is greater than the overlapping area between the first clamping side wall 103 and the photovoltaic laminate 101.

[0050] In the embodiment of the present application, the overlapping area between the connecting base plate 109 and the photovoltaic laminate 101 is larger than the overlapping area between the first clamping side wall 103 and the photovoltaic laminate 101, that is, the A surface is smaller than the C surface. By increasing the area of ​​the connecting base plate 109, the stability of the installation of the photovoltaic laminate 101 can be effectively increased, thereby facilitating the reliable installation of the photovoltaic module.

[0051] Reference Figure 3 and Figure 4 As shown, as an optional embodiment, the second clamping side wall 104 is located between the first clamping side wall 103 and the connecting base 109, and the second clamping side wall 104, the first clamping side wall 103 and the connecting base 109 are parallel to each other. It should be noted that the distance between the first clamping side wall 103 and the second clamping side wall 104 can be set according to the thickness of the photovoltaic laminate 101.

[0052] Reference Figure 7 As shown, the embodiment of the present application further discloses a photovoltaic assembly, including a photovoltaic laminate 101 and the above-mentioned photovoltaic frame; the photovoltaic frame is arranged around the periphery of the photovoltaic laminate 101.

[0053] Compared with the prior art, the embodiment of the present application avoids providing a glue overflow groove on the first clamping side wall 103, thereby effectively reducing the protruding thickness of the frame on the light incident surface, thereby reducing rainwater accumulation and effectively improving the power generation capacity of the photovoltaic module.
