[0050] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0051] Existing photovoltaic (PV) frames typically have mounting grooves on the inner side, into which PV laminates are snapped. The PV laminates and mounting grooves are sealed with sealant. The top of the frame has a pressing edge extending towards the center, protruding above the upper surface of the PV laminate and abutting against it to limit and reinforce the PV module. However, because this pressing edge protrudes above the upper surface of the PV laminate, it easily obstructs rainwater flow. Over time, dust cannot be washed away from the PV laminate, leading to a large accumulation of dust. This dust can obstruct the PV module, affecting power generation and even causing hot spot effects, resulting in a decline in PV module performance.

[0052] In view of this, the present invention provides a photovoltaic frame, including a first mounting frame extending along a first direction and a second mounting frame extending along a second direction; the first mounting frame has a first supporting surface and a first stop edge at its top, and the second mounting frame has a second supporting surface and a second stop edge at its top. The first supporting surface and the second supporting surface are used to support the photovoltaic laminate, and the first stop edge and the second stop edge are configured to be positioned around the periphery of the photovoltaic laminate; the top of the first stop edge has a pressing edge, and the bottom of the pressing edge abuts against the upper surface of the photovoltaic laminate. The first supporting surface, the first stop edge, and the pressing edge together form a mounting groove, and the periphery of the photovoltaic laminate is engaged in the mounting groove; the second stop edge abuts against the side of the photovoltaic laminate, and the second stop edge does not protrude above the upper surface of the photovoltaic laminate. The side of the second stop edge facing the photovoltaic laminate has a first adhesive groove. The photovoltaic frame provided by this utility model has a second baffle on the second mounting bracket abutting against the side of the photovoltaic laminate, and the second baffle is not higher than the upper surface of the photovoltaic laminate. This can prevent the second baffle from blocking the flow of rainwater on the photovoltaic laminate, allowing dust and rainwater on the photovoltaic module to be discharged from the second baffle to the outside of the photovoltaic module, thereby reducing the accumulation of dust on the surface of the photovoltaic laminate. At the same time, by setting a first adhesive groove on the side of the second baffle facing the photovoltaic laminate, the first adhesive groove can hold the sealant between the photovoltaic laminate and the photovoltaic frame, preventing the sealant from overflowing onto the surface of the photovoltaic laminate, thereby improving the power generation efficiency of the photovoltaic laminate.

[0054] You can refer to this. Figures 1 to 5This utility model provides a photovoltaic frame 100 for mounting a photovoltaic laminate 200, including multiple mounting brackets connected end-to-end. The mounting brackets include a first mounting bracket 110 extending along a first direction X and a second mounting bracket 120 extending along a second direction Y, wherein the first direction X and the second direction Y are perpendicular. The length of the first mounting bracket 110 is greater than the length of the second mounting bracket 120. The top of the first mounting bracket 110 has a first support surface 111 and a first edge 112, and the top of the second mounting bracket 120 has a second support surface 121 and a second edge 122. The first support surface 111 and the second support surface 121 support the photovoltaic laminate 200, and the first edge... The first support surface 111, the first support surface 112, and the second stop 122 are configured to abut against the periphery of the photovoltaic laminate 200. The top of the first support surface 112 has a pressing edge 113 extending toward the center of the frame 100. The bottom of the pressing edge 113 is configured to abut against the upper surface of the photovoltaic laminate 200. The first support surface 111, the first support surface 112, and the pressing edge 113 together form a mounting groove 114. The periphery of the photovoltaic laminate 200 is engaged in the mounting groove 114. The second support surface 122 is configured to abut against the side of the photovoltaic laminate 200. The second support surface 122 does not protrude above the upper surface of the photovoltaic laminate 200. The side of the second support surface 122 facing the photovoltaic laminate 200 has a first adhesive groove 123.

[0055] The photovoltaic frame 100 provided in this embodiment of the utility model, by having the second baffle 122 on the second mounting bracket 120 abut against the side of the photovoltaic laminate 200 and ensuring that the second baffle 122 does not protrude above the upper surface of the photovoltaic laminate 200, can prevent the second baffle 122 from blocking the flow of rainwater on the photovoltaic laminate 200. This allows dust and rainwater on the photovoltaic module to be discharged from the second baffle 122 to the outside of the photovoltaic module, thereby reducing the accumulation of dust on the surface of the photovoltaic laminate 200. At the same time, by providing a first adhesive groove 123 on the side of the second baffle 122 facing the photovoltaic laminate 200, the first adhesive groove 123 can accommodate the sealant between the photovoltaic laminate 200 and the photovoltaic frame 100, improving the sealing and adhesion between the side of the photovoltaic laminate 200 and the second baffle 122 of the photovoltaic frame 100, while preventing the sealant from overflowing onto the upper surface of the photovoltaic laminate 200, thereby affecting the power generation efficiency of the photovoltaic laminate 200.

[0056] In the above embodiments, a second adhesive groove 124 may be provided on the second support surface 121. The second adhesive groove 124 can be used to accommodate more sealant, improve the sealing and adhesion between the bottom surface of the photovoltaic laminate 200 and the second support surface 121 of the photovoltaic frame 100, and avoid dust accumulation in the gap between the photovoltaic frame 100 and the photovoltaic laminate 200 due to insufficient sealing, thereby further improving the power generation efficiency of the photovoltaic laminate 200.

[0057] In the above embodiments, the cross-section of the second adhesive container 124 can be an inverted trapezoidal shape. It can be understood that the adhesive container is an inverted trapezoidal structure with the upper opening larger than the bottom. Without increasing the amount of sealant used, the contact area between the sealant in the second adhesive container 124 and the photovoltaic laminate 200 can be increased, thereby further increasing the sealing and adhesion between the bottom surface of the photovoltaic laminate 200 and the second support surface 121 of the photovoltaic frame 100, thereby further improving the power generation efficiency of the photovoltaic laminate 200.

[0058] In the above embodiments, there may be at least two second adhesive grooves 124, which are spaced apart along the width direction of the second support surface 121. A support portion 125 for supporting the bottom of the photovoltaic laminate 200 is formed between two adjacent second adhesive grooves 124. By increasing the number of second adhesive grooves 124, the sealing and adhesion between the bottom surface of the photovoltaic laminate 200 and the second support surface 121 of the photovoltaic frame 100 can be further increased. At the same time, a new support portion 125 for supporting the bottom of the photovoltaic laminate can be formed between two second adhesive grooves 124. This allows at least three supports to be formed for the photovoltaic laminate 200 by the second support surface 121 and the support portion 125 on both sides of the second adhesive groove 124, thereby reducing the contact area between the photovoltaic laminate 200 and the second support surface 121. As a result, a certain space for thermal expansion can be left for the photovoltaic laminate 200 and the photovoltaic frame 100, preventing the photovoltaic laminate 200 and the photovoltaic frame 100 from bursting due to stress that cannot be released after thermal expansion.

[0059] In the above embodiments, the depth of the second adhesive reservoir 124 can be 0.3mm-0.5mm. Insufficient depth of the second adhesive reservoir 124 will result in insufficient adhesive storage, thereby reducing the sealing and adhesion between the photovoltaic frame 100 and the photovoltaic laminate 200. Excessive depth of the second adhesive reservoir 124 will affect the structural strength of the second support surface 121, thereby reducing the load-bearing capacity of the second support surface 121.

[0060] like Figure 5 As shown in the above embodiment, the end of the second support surface 121 near the center of the frame 100 can be made into a slope 126, and the slope 126 slopes downward along the direction from the second support surface 121 towards the center of the frame 100. The slope 126 design of the edge of the second support surface 121 facilitates the overflow of excess sealant from the back of the photovoltaic laminate 200 along the slope 126, preventing the sealant from overflowing from the upper surface of the photovoltaic laminate 200, and further increasing the power generation efficiency of the photovoltaic laminate 200.

[0061] In the above embodiments, the cross-section of the first adhesive receiving groove 123 can be arc-shaped. On the one hand, it can facilitate the overflow of sealant into the first adhesive receiving groove 123. On the other hand, it can reduce the impact on the structural strength of the second retaining edge 122.

[0062] In the above embodiments, the bottom of the pressing edge 113 may have a third adhesive groove 115, which can store overflowing sealant and improve the sealing and adhesion between the upper edge of the photovoltaic laminate 200 and the pressing edge 113 of the photovoltaic frame 100.

[0063] In the above embodiments, the top of the pressing edge 113 may have anti-slip texture 116, which can facilitate the connection between the pressing edge 113 and other reinforcements outside the photovoltaic frame 100, further improving the sealing and adhesion between the upper edge of the photovoltaic laminate 200 and the pressing edge 113 of the photovoltaic frame 100.

[0064] Furthermore, this utility model embodiment also provides a photovoltaic module, including a photovoltaic laminate 200 and a photovoltaic frame 100 as described in the above embodiment. The photovoltaic frame 100 includes a first mounting bracket 110 extending along a first direction X and a second mounting bracket 120 extending along a second direction Y; the first mounting bracket 110 has a first support surface 111 and a first edge 112 at its top, and the second mounting bracket 120 has a second support surface 121 and a second edge 122 at its top. The first support surface 111 and the second support surface 121 support the photovoltaic laminate 200, and the first edge 112 and the second edge 122 are configured to block the periphery of the photovoltaic laminate 200; the top of the first edge 112 has an edge facing... A pressing edge 113 extends from the center of frame 100. The bottom of pressing edge 113 is configured to abut against the upper surface of photovoltaic laminate 200. The first support surface 111, the first stop edge 112, and pressing edge 113 together form a mounting groove 114. The periphery of photovoltaic laminate 200 is engaged in the mounting groove 114. The second stop edge 122 is configured to abut against the side of photovoltaic laminate 200. The second stop edge 122 does not protrude above the upper surface of photovoltaic laminate 200. The side of the second stop edge 122 facing photovoltaic laminate 200 has a first adhesive groove 123. The photovoltaic frame 100, by having the second baffle 122 on the second mounting bracket 120 abut against the side of the photovoltaic laminate 200 and ensuring that the second baffle 122 does not protrude above the upper surface of the photovoltaic laminate 200, can prevent the second baffle 122 from blocking the flow of rainwater on the photovoltaic laminate 200. This allows dust and rainwater on the photovoltaic module to be discharged from the second baffle 122 to the outside of the photovoltaic module, thereby reducing the accumulation of dust on the surface of the photovoltaic laminate 200. At the same time, by providing a first adhesive groove 123 on the side of the second baffle 122 facing the photovoltaic laminate 200, the first adhesive groove 123 can accommodate the sealant between the photovoltaic laminate 200 and the photovoltaic frame 100, preventing the sealant from overflowing onto the surface of the photovoltaic laminate 200, thereby improving the power generation efficiency of the photovoltaic laminate 200.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
