[0035] The technical solution provided by the embodiments of the present application is described below in conjunction with the accompanying drawings.
[0036] As shown in FIG. 1 , a conventional photovoltaic frame 01 is a C-shaped component with laminates fixed on three sides, and the photovoltaic frame 01 generally has an A-surface 011 structure. When the laminate is installed on such a photovoltaic frame 01, the A-surface 011 will be higher than the light-receiving surface (top surface) of the laminate. Due to the obstruction of the A-surface 011, the laminate will accumulate a lot of dust during long-term use. After being naturally washed by rainwater, dew, etc., the dust will be washed to the area of the laminate close to the A-surface 011, causing water accumulation, dust accumulation and other undesirable phenomena on the light-receiving surface of the laminate, resulting in the light-receiving surface of the laminate being blocked, thereby reducing the power generation efficiency of the photovoltaic module and even causing hot spots.
[0037] In view of the above problems, referring to FIG. 2 and FIG. 3, the present application provides a photovoltaic assembly 200, which includes a photovoltaic frame 100 and a laminate 210, and the photovoltaic frame 100 is used for the bearing installation of the laminate 210. The photovoltaic frame 100 is provided with a bearing surface 110 and an extension portion 120 extending from the bearing surface 110, wherein: the bearing surface 110 and the extension portion 120 are both configured to extend longitudinally along the length direction of the photovoltaic frame 100, in other words, referring to FIG. 2, the bearing surface 110 and the extension portion 120 are both extended in a direction perpendicular to the paper surface. The extension portion 120 is used to abut the side of the laminate 210, and the bearing surface 110 is used to support the backlight surface 212 (bottom surface) of the laminate 210. For example, in this embodiment, the extension portion 120 and the bearing surface 110 jointly form a bearing space, and the end of the laminate 210 can be carried in the bearing space, so that the laminate 210 can be pre-installed on the photovoltaic frame 100 by placing, bridging, etc. Furthermore, when the laminate 210 is installed on the photovoltaic frame 100 , the top of the extension 120 is lower than or flush with the light receiving surface 211 of the laminate 210 , that is, H1≤H2 as shown in FIG. 3 , and the height of the extension 120 is less than or equal to the thickness of the laminate 210 . In one of the embodiments, the height of the extension 120 is less than the thickness of the laminate 210. When the laminate 210 is installed on the photovoltaic frame 100, the light-receiving surface 211 (top surface) of the laminate 210 protrudes from the top of the extension 120. For example, in the present embodiment, when the top of the extension 120 is lower than the light-receiving surface 211 of the laminate 210, in the thickness direction of the laminate 210, the distance that the light-receiving surface 211 of the laminate 210 is higher than the top of the extension 120 is less than or equal to 0.2 mm, that is, H2-H1≤0.2 mm. If the light-receiving surface 211 of the laminate 210 is higher than the top of the extension 120 by too much distance, the laminate 210 may easily slip out of the bearing space. In another embodiment, the height of the extension portion 120 is equal to the thickness of the laminate 210 , and when the laminate 210 is installed on the photovoltaic frame 100 , the light-receiving surface 211 of the laminate 210 is flush with the top of the extension portion 120 . Regardless of which of the above methods is used, after the laminate 210 is installed on the photovoltaic frame 100, since the top of the extension 120 is lower than or flush with the light receiving surface 211 of the laminate 210, and the light receiving surface 211 of the laminate 210 is not lower than the top of the extension 120, the dust accumulated on the light receiving surface 211 of the laminate 210 can be smoothly discharged from the laminate 210 under the natural scouring action of rain, dew, etc., and will not cause water accumulation, dust accumulation and other adverse phenomena on the light receiving surface 211 of the laminate 210. The photovoltaic frame 100 will not block the light receiving surface 211 of the laminate 210, which can improve the power generation efficiency of the photovoltaic module 200 and effectively avoid the hot spot phenomenon of the photovoltaic module 200.
[0038] In addition, a first glue overflow groove 130 is provided at the connection between the extension part 120 and the bearing surface 110. Since the laminate 210 is bonded to the extension part 120 and the bearing surface 110 by silicone, the first glue overflow groove 130 can be used for filling with silicone and controlling glue overflow, and silicone can be filled into the first glue overflow groove 130, and the silicone bonds the side of the laminate 210 to the side of the extension part 120, and bonds the backlight surface 212 of the laminate 210 to the bearing surface 110, and the laminate 210 is supported by the bearing surface 110, so as to realize the installation and fixation of the laminate 210 on the photovoltaic frame 100. Furthermore, since silicone is fluid, under the action of gravity of the laminate 210, the silicone is squeezed and evenly coated on the gap between the laminate 210 and the supporting surface 110 and the extension portion 120. The first glue overflow groove 130 can accommodate excess silicone to prevent excess silicone from overflowing onto the surface of the laminate 210, thereby preventing the silicone from blocking the surface of the laminate 210, thereby ensuring that the laminate 210 has a higher power generation efficiency.
[0039] In one embodiment, referring to FIG. 2 and FIG. 3 , a second glue overflow groove 140 is provided on the side of the extension portion 120 close to the bearing surface 110; and / or a third glue overflow groove 150 is further provided on the bearing surface 110, and the third glue overflow groove 150 is located on the side of the first glue overflow groove 130 away from the extension portion 120. In one embodiment, the second glue overflow groove 140 is provided only on the side of the extension portion 120 close to the bearing surface 110; in another embodiment, the third glue overflow groove 150 is provided only on the bearing surface 110; in yet another embodiment, the second glue overflow groove 140 is provided on the side of the extension portion 120 close to the bearing surface 110, and the third glue overflow groove 150 is provided on the bearing surface 110. The above-mentioned photovoltaic frame 100, the first glue overflow groove 130, the second glue overflow groove 140 and the third glue overflow groove 150 can all be used for filling with silicone and controlling glue overflow to accommodate more silicone filling, thereby improving the bonding strength of the laminate 210 on the photovoltaic frame 100, and the first glue overflow groove 130, the second glue overflow groove 140 and the third glue overflow groove 150 can accommodate more silicone to prevent excessive silicone from overflowing onto the surface of the laminate 210 under the extrusion of the laminate 210, resulting in a decrease in the power generation efficiency of the laminate 210.
[0040] Specifically, as shown in FIG. 2 , in this embodiment, a plurality of first protrusions 121 are convexly provided on the side of the extension portion 120, and a second glue overflow groove 140 is formed between two adjacent first protrusions 121 and the side of the extension portion 120; similarly, a plurality of second protrusions 111 are convexly provided on the bearing surface 110, and a third glue overflow groove 150 is formed between two adjacent second protrusions 111 and the bearing surface 110. When the laminate 210 is overlapped on the photovoltaic frame 100, the side of the laminate 210 abuts against the first protrusions 121, and the backlight surface 212 of the laminate 210 overlaps the second protrusions 111, so that there is a gap between the side of the laminate 210 and the side of the extension portion 120, and between the backlight surface 212 of the laminate 210 and the bearing surface 110. At this time, the laminate 210 can be overlapped on the photovoltaic frame 100 first, and silicone can be filled into the first glue overflow groove 130, the second glue overflow groove 140 and the third glue overflow groove 150. After the silicone is fixed, the silicone is evenly coated on the gap between the laminate 210 and the supporting surface 110 and the extension 210. The side of the laminate 210 can be bonded to the side of the extension 120, and the backlight surface 212 of the laminate 210 can be bonded to the supporting surface 110 indirectly, so as to achieve the bonding and fixation of the laminate 210 on the photovoltaic frame 100.
[0041] Further, referring to FIG. 2 and FIG. 3 , there are a plurality of third overflow glue grooves 150, and the plurality of third overflow glue grooves 150 are arranged side by side at intervals in a direction away from the first overflow glue groove 130. In this way, the plurality of third overflow glue grooves 150 can accommodate more silicone filling, further improving the bonding strength of the laminate 210 on the photovoltaic frame 100, and the plurality of third overflow glue grooves 150 can accommodate more silicone, further preventing excessive silicone from overflowing onto the surface of the laminate 210, avoiding silicone from blocking the surface of the laminate 210, and thus ensuring that the laminate 210 has a higher power generation efficiency.
[0042] In order to support the laminate 210 installed on the photovoltaic frame 100, in one embodiment, referring to FIG. 2 and FIG. 3 , the photovoltaic frame 100 is further provided with a support protrusion 112 protruding from the bearing surface 110, and the support protrusion 112 is located on the side of the bearing surface 110 away from the extension 120. When the laminate 210 is placed on the photovoltaic frame 100, the support protrusion 112 supports the laminate 210 and ensures that there is a gap between the backlight surface 212 of the laminate 210 and the bearing surface 110, so as to facilitate the filling of silicone in the gap between the backlight surface 212 of the laminate 210 and the bearing surface 110, and facilitate the bonding and fixing operation of the laminate 210 on the photovoltaic frame 100.
[0043] In one embodiment, referring to FIG. 2 and FIG. 3 , the photovoltaic frame 100 includes a bottom plate 160, a support plate 170, a first side plate 180, and a second side plate 190. The bottom plate 160 and the support plate 170 are spaced apart along a first direction (the X direction shown in FIG. 2 ), a bearing surface 110 is provided on the side of the support plate 170 facing away from the bottom plate 160, and the first side plate 180 and the second side plate 190 are spaced apart along a second direction (the Y direction shown in FIG. 2 ). In this embodiment, the first direction and the second direction are perpendicular to each other. Of course, in other feasible embodiments, the first direction and the second direction can also be other angles.
[0044] Among them, the first side panel 180 is connected to the bottom plate 160 and the support plate 170, and the end of the first side panel 180 extends out of the bearing surface 110 along the first direction to form an extension portion 120, and the second side panel 190 is connected between the bottom plate 160 and the support plate 170, that is, the bottom plate 160, the support plate 170, the first side panel 180 and the second side panel 190 are arranged to form a frame structure. When the laminate 210 is installed on the photovoltaic frame 100, the support plate 170, the first side panel 180 and the second side panel 190 can support the laminate 210, and the bottom plate 160 can be installed and connected with other structures to connect the laminate 210 to other structures. In addition, the bottom plate 160, the support plate 170, the first side plate 180 and the second side plate 190 are surrounded to form a cavity 191. Since the bottom plate 160, the support plate 170, the first side plate 180 and the second side plate 190 are connected as a whole through the angle code, the cavity 191 can be used for the locking operation of the angle code, thereby facilitating the fixed connection between the bottom plate 160, the support plate 170, the first side plate 180 and the second side plate 190.
[0045] In one embodiment, referring to Figures 2 and 3, the orthographic projection of the support protrusion 112 on the base plate 160 is at least partially located outside the orthographic projection of the second side plate 190 on the base plate 160. Taking the perspective of Figure 2 as an example, the support protrusion 112 is located on the right side of the second side plate 190. When the laminate 210 is installed on the photovoltaic frame 100, the laminate 210 overlaps the support protrusion 112, and the gravity of the laminate 210 will be applied to the support protrusion 112. The support protrusion 112 is arranged on the outside of the second side plate 190, so that the force transmitted to the second side plate 190 through the support protrusion 112 is small, thereby preventing the second side plate 190 from deforming, bending, or even breaking during the long-term support of the laminate 210, thereby improving the service life of the photovoltaic frame 100.
[0046] Of course, in another feasible embodiment, referring to Figure 4, the surface of the support protrusion 112 away from the first side panel 180 along the second direction is flush with the surface of the second side panel 190 away from the first side panel 180. Taking the perspective of Figure 4 as an example, the support protrusion 112 is located directly above the second side panel 190. The support protrusion 112 can also support the laminate 210 overlapped on the photovoltaic frame 100.
[0047] In order to further improve the service life of the photovoltaic frame 100, in one embodiment, referring to FIG. 2 and FIG. 3, the end of the support plate 170 away from the first side plate 180 along the second direction extends out of the second side plate 190. If the support plate 170 includes a middle section and ends located at opposite ends of the middle section, when the second side plate 190 is connected to the support plate 170, the connection between the support plate 170 and the second side plate 190 is located at the middle section of the support plate 170. In the above-mentioned photovoltaic frame 100, the support plate 170 is set to be longer. When the laminate 210 is installed on the photovoltaic frame 100, the contact area between the laminate 210 and the support plate 170 is larger, and the support plate 170 has a better supporting effect on the laminate 210. The support plate 170 can decompose the force applied by the laminate 210 on the support plate 170, and the force of the laminate 210 acting on the support plate 170 per unit area is reduced, so that the force acting on the first side plate 180 and the second side plate 190 is further reduced, thereby preventing the second side plate 190 from being deformed, bent, or even broken during the long-term support of the laminate 210, thereby further improving the service life of the photovoltaic frame 100.
[0048] In one embodiment, referring to FIG. 2 and FIG. 3 , the cross section of the first overflow glue groove 130 perpendicular to the length direction of the photovoltaic frame 100 has an arc-shaped outer contour line, and the outer contour line extends from the bearing surface 110 to the side of the extension 120 close to the bearing surface 110. Since the first overflow glue groove 130 has an arc-shaped outer contour line, the first overflow glue groove 130 can accommodate more silica gel, prevent excessive silica gel from overflowing to the surface of the laminate 210, and avoid silica gel from blocking the surface of the laminate 210, thereby ensuring that the laminate 210 has a higher power generation efficiency. In addition, when the laminate 210 is installed on the photovoltaic frame 100, the first overflow glue groove 130 with an arc-shaped outer contour line can avoid interference with the edge portion of the laminate 210, which facilitates the installation operation of the laminate 210 on the photovoltaic frame 100. It should be noted that the cross section of the first overflow glue groove 130 perpendicular to the length direction of the photovoltaic frame 100 is not limited to the above-mentioned arc-shaped outer contour line, and can also be a V-shaped or other shaped outer contour line.
[0049] In order to facilitate the installation and fixation of the laminate 210 on the photovoltaic frame 100, in one embodiment, referring to Figures 2 and 3, the extension portion 120 and the bearing surface 110 are perpendicular to each other, so that the opening end of the bearing space formed by the bearing surface 110 and the bearing surface 110 is open, which facilitates the placement of the laminate 210 into the bearing space and the installation and fixation of the laminate 210 on the photovoltaic frame 100.
[0050] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.
[0051] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
