Description

[Technical Field]

[0001] The present application relates to the technical field of photovoltaic modules, and in particular to photovoltaic frames and photovoltaic modules. [Background technology]

[0002] A photovoltaic module generally consists of a photovoltaic stack and a photovoltaic frame for mounting the stack. The photovoltaic frame is an important component of the photovoltaic module, and serves to fix and seal the stack, facilitating transportation and installation of the photovoltaic module. The frame structure of the photovoltaic module has a significant impact on the installation and service life of the photovoltaic module.

[0003] A typical photovoltaic frame (01) is a C-shaped component that secures the laminate on three sides. As shown in Figure 1, photovoltaic frames typically have an A-side (011) structure. When a laminate is attached to such a photovoltaic frame, the A-side is located higher than the light-receiving surface of the laminate. Due to the shielding effect of the A-side, a large amount of dust accumulates on the laminate during extended use. After natural cleaning by rainwater or dew, the dust is washed away to the area close to the A-side of the laminate, resulting in problems such as water puddles and ash accumulation on the light-receiving surface of the laminate. To reduce the shielding effect of photovoltaic frames, photovoltaic frames that eliminate the A-side structure design are commercially available. However, such frame structures have insufficient adhesive strength to the laminate, and the adhesive is prone to spill onto the surface of the laminate during bonding, creating a shielding effect on the surface of the laminate and negatively affecting the aesthetics of the laminate.

[0016]

[0003] In the photovoltaic frame and photovoltaic module described above, when the stack is to be attached to the photovoltaic frame, a predetermined amount of adhesive is filled into the adhesive groove structure and the first adhesive overflow groove, and the laminate is adhered and fixed in the mounting groove by an adhesive layer, thereby achieving a fixed attachment of the stack to the photovoltaic frame. In the photovoltaic frame provided herein, when the laminate is attached to the photovoltaic frame, the upper end of the protruding portion is lower than the light-receiving surface of the laminate or is flush with the light-receiving surface. That is, the light-receiving surface of the laminate is not lower than the upper end of the protruding portion. This allows dust accumulated on the light-receiving surface of the laminate to be smoothly discharged from the laminate by natural washing away of rainwater, dew, etc., preventing problems such as puddles or ash accumulation on the light-receiving surface of the laminate. The light-receiving surface of the laminate is not blocked by the photovoltaic frame, improving the power generation efficiency of the laminate and effectively preventing the occurrence of hot spots on the laminate. In addition, the combination of the first adhesive overflow groove and the adhesive groove structure increases the adhesive capacity, improving the adhesive strength of the laminate to the photovoltaic frame. When the adhesive in the adhesive groove structure is pressed by the laminate and spills out during installation, the first adhesive overflow groove contains the spilled adhesive, preventing it from spilling onto the backlight surface of the laminate. Furthermore, the adhesive overflow plate can support the laminate, effectively preventing problems such as deformation and even breakage when the photovoltaic frame fixes the laminate over a long period of time, thereby improving the service life of the photovoltaic frame.

[0024] Hereinafter, the technical means provided in the embodiments of the present application will be described with reference to the drawings.

[0025] As shown in Figure 1, a typical photovoltaic frame 01 is a C-shaped member that fixes the laminate on three sides, and the photovoltaic frame 01 generally has an A-side 011 structure. When the laminate is attached to such a photovoltaic frame 01, the A-side 011 is located higher than the light-receiving surface (top surface) of the laminate. Because the A-side 011 is blocked, a lot of dust accumulates on the laminate during long-term use. After natural cleaning by rainwater or dew, the dust is washed away to the area close to the A-side 011 of the laminate, causing problems such as water puddles and ash accumulation on the light-receiving surface of the laminate. This blocks the light-receiving surface of the laminate, reducing the power generation efficiency of the photovoltaic module and even causing hot spots.

[0026] To address the above-mentioned problems, the present application provides a photovoltaic frame 100, which includes a support plate 110, a first side plate 120, and a second side plate 130, as shown in Figures 2 and 3. The photovoltaic frame 100 is used to mount a laminate 200. The support plate 110 is used to support the backlight surface 210 of the laminate 200. For example, at least a portion of the backlight surface 210 of the laminate 200 is placed on the support plate 110, thereby realizing the mounting and fixing of the photovoltaic frame 100 to the laminate 200.

[0027] The first side plate 120 and the second side plate 130 are connected to opposite sides of the support plate 110, respectively, and the first side plate 120 has a protruding portion 121 that protrudes from the support plate 110. As an example, the first side plate 120, the second side plate 130, and the support plate 110 are all configured to extend longitudinally along the longitudinal direction of the photovoltaic frame 100. That is, as shown in FIG. 2 , the first side plate 120, the second side plate 130, and the support plate 110 all extend in a direction perpendicular to the plane of the paper, and the protruding portion 121 protrudes vertically or approximately vertically in the plane of the paper. The protruding portion 121 and the support plate 110 surround and form a mounting groove 140 that is used to accommodate the stack 200; for example, a side region of the stack 200 can be accommodated within the mounting groove 140. The protruding portion 121 and / or the support plate 110 are provided with an adhesive groove structure 150 that communicates with the mounting groove 140. The adhesive groove structure 150 is used to fill and accommodate an adhesive (e.g., silica gel). An adhesive overflow plate 131 is provided on the side of the second side plate 130 that faces away from the first side plate 120 and protrudes toward the side that faces away from the first side plate 120. In this embodiment, as shown in FIG. 2 , the adhesive overflow plate 131 extends longitudinally along the length of the photovoltaic frame 100 and also protrudes horizontally or approximately horizontally on the paper surface. The adhesive overflow plate 131 and the second side plate 130 surround and form a first adhesive overflow groove 132 that communicates with the mounting groove 140. When the laminate 200 is to be attached to the photovoltaic frame 100, a predetermined amount of adhesive is filled into the adhesive groove structure 150 and the first adhesive overflow groove 132, and after the adhesive hardens to form an adhesive layer 300, the laminate 200 is adhesively fixed in the mounting groove 140 by the adhesive layer 300, thereby realizing a fixed attachment of the laminate 200 to the photovoltaic frame 100.

[0028] When the laminate 200 is attached to the photovoltaic frame 100, the upper end of the protruding portion 121 is lower than the light-receiving surface 220 of the laminate 200 or is flush with the light-receiving surface 220. That is, the light-receiving surface 220 of the laminate 200 is not lower than the upper end of the protruding portion 121. This allows dust that has accumulated on the light-receiving surface 220 of the laminate 200 to be smoothly discharged from the laminate 200 by natural washing away of rainwater, dew, etc., and prevents problems such as puddles or ash accumulation on the light-receiving surface 220 of the laminate 200. The photovoltaic frame 100 does not have any effect such as blocking the light-receiving surface 220 of the laminate 200. This improves the power generation efficiency of the laminate 200 and effectively prevents the occurrence of hot spots on the laminate 200.

[0029] The photovoltaic frame 100 described above can increase the adhesive capacity by combining the first adhesive overflow groove 132 with the adhesive groove structure 150, thereby improving the adhesive strength of the laminate 200 to the photovoltaic frame 100. Furthermore, when the adhesive in the adhesive groove structure 150 is pressed by the laminate 200 and spills out during installation, the first adhesive overflow groove 132 can contain the adhesive spilled from the adhesive groove structure 150, preventing the adhesive from spilling onto the backlight surface 210 of the laminate 200. Furthermore, the adhesive overflow plate 131 can support the laminate 200, which effectively prevents problems such as deformation and even breakage of the photovoltaic frame 100 during the long-term fixing process of the laminate 200, thereby improving the service life of the photovoltaic frame 100.

[0030] 2 and 3, when the upper end of the overhanging portion 121 is lower than the light receiving surface 220 of the laminate 200, the light receiving surface 220 of the laminate 200 is 20 mm or less higher than the upper end of the overhanging portion 121 in the thickness direction of the laminate 200, that is, H5≦20 mm as shown in FIG. 3, where H5 may be, for example, 0.1 mm, 5 mm, 10 mm, 15 mm, or 20 mm. However, the specific value of H5 is not limited to this application and can be selectively set depending on the thickness of the laminate 200. Note that if the light receiving surface 220 of the laminate 200 is too higher than the upper end of the overhanging portion 121, the laminate 200 is more likely to slip out of the mounting groove 140.

[0031] 2 to 4 , an adhesive barrier plate 122 is bent at the end of the overhanging portion 121 away from the support plate 110, and the adhesive barrier plate 122 overhangs toward the inside of the mounting groove 140. A second adhesive overflow groove 151 is surrounded and formed by the adhesive barrier plate 122, the overhanging portion 121, and the support plate 110, and the second adhesive overflow groove 151 communicates with the mounting groove 140. The second adhesive overflow groove 151 may be used to contain adhesive, and since the second adhesive overflow groove 151 communicates with the mounting groove 140, when the laminate 200 is to be fixed to the photovoltaic frame 100, the adhesive in the second adhesive overflow groove 151 flows into the mounting groove 140, thereby adhering and fixing the laminate 200 to the photovoltaic frame 100. Furthermore, since the adhesive barrier plate 122 is formed by folding at the protruding portion 121, the adhesive in the second adhesive overflow groove 151 is contained within the second adhesive overflow groove 151 as much as possible, which prevents the adhesive in the second adhesive overflow groove 151 from spilling out to the outside while under pressure and causing poor appearance of the photovoltaic frame 100 and / or laminate 200, and also ensures that as much adhesive as possible in the second adhesive overflow groove 151 is used to bond the laminate 200, thereby improving the adhesive strength of the laminate 200 to the photovoltaic frame 100.

[0032] 4 and 5 , the support plate 110 has a support surface 111 that supports the laminate 200. The adhesive barrier plate 122 has a first end 1221 connected to the protruding portion 121, a second end 1222 extending into the mounting groove 140, and a transition surface 1223 connecting the first end 1221 and the second end 1222. As shown in FIG. 6 , the length of the second end 1222 extending into the mounting groove 140 is defined as D1, where D1 satisfies the following conditions: 1 mm≦D1≦10 mm. D1 may be, for example, 1 mm, 3 mm, 5 mm, 8 mm, or 10 mm; the specific value of D1 is not limited in the present application. The transition surface 1223 is located on the side of the adhesive barrier plate 122 that is closer to the support plate 110; that is, the transition surface 1223 faces the support surface 111. In the protruding direction of the protruding portion 121, the distance from the connection point between the transition surface 1223 and the first end 1221 to the support surface 111 is H1, and the distance from the connection point between the transition surface 1223 and the second end 1222 to the support surface 111 is H2, and H1>H2 is satisfied. In other words, as shown in FIG. 5, the connection point between the transition surface 1223 and the first end 1221 is above the connection point between the transition surface 1223 and the second end 1222. That is, the transition surface 1223 is higher on the left and lower on the right in the horizontal direction. As a result, the outer contour forming the second adhesive overflow groove 151 becomes barbed, which prevents the adhesive in the second adhesive overflow groove 151 from spilling out under pressure and causing poor appearance of the photovoltaic frame 100 and / or the laminate 200, and ensures that as much adhesive as possible in the second adhesive overflow groove 151 is used to bond the laminate 200, improving the adhesive strength of the laminate 200 to the photovoltaic frame 100.

[0033] In this embodiment, the surface of the adhesive barrier plate 122 opposite the support plate 110 is parallel to the support surface 111 and is lower than or flush with the light-receiving surface 220 of the laminate 200 when the laminate 200 is attached to the photovoltaic frame 100, eliminating any effect such as shielding of the light-receiving surface 220 of the laminate 200 by the photovoltaic frame 100. Furthermore, in the protruding direction of the protruding portion 121, the thickness of the first end 1221 is H3 and the thickness of the second end 1222 is H4, with 0.2H4≦H3≦0.8H4 so that H1>H2 holds. This ensures that the outer contour forming the second adhesive overflow groove 151 is barbed. For example, 0.5 mm≦H3≦10 mm is satisfied, and H3 may be, for example, 0.5 mm, 2 mm, 5 mm, 7 mm, or 10 mm. Also, 1 mm≦H4≦20 mm is satisfied, and H4 may be, for example, 1 mm, 5 mm, 10 mm, 15 mm, or 20 mm. The specific values ​​of H3 and H4 are not limited in the present application. In one embodiment, as shown in FIG. 5 , transition surface 1223 is an inclined surface. When the angle between transition surface 1223 and support surface 111 is defined as α, the angle satisfies 0<α<90°. α may be, for example, 15°, 30°, 45°, 60°, or 75°. The specific value of α is not limited in the present application. In another embodiment, as shown in FIG. 6 , transition surface 1223 may be a curved surface. Transition surface 1223 tends to be higher on the left and lower on the right in the horizontal direction. 2 to 4, at least one first protrusion 123 is provided on the side surface of overhanging portion 121 closer to mounting groove 140, and second adhesive overflow groove 151 is formed and surrounded by first protrusion 123, adhesive barrier plate 122, and overhanging portion 121, and second adhesive overflow groove 151 is also formed and surrounded by first protrusion 123, support plate 110, and overhanging portion 121. When there are multiple first protrusions 123, second adhesive overflow groove 151 is also formed and surrounded by two adjacent first protrusions 123 and overhanging portions 121.In this way, the first protrusion 123 can improve the structural strength of the protrusion 121 and form a plurality of second adhesive overflow grooves 151 in the photovoltaic frame 100, and any of the plurality of second adhesive overflow grooves 151 can be used to accommodate adhesive, thereby increasing the adhesive capacity and improving the adhesive strength of the laminate 200 to the photovoltaic frame 100.

[0034] 2 to 4 and 6A, a plurality of second protrusions 112 are provided on the end face of the support plate 110 that is closer to the mounting groove 140, and a third adhesive overflow groove 152 is formed by being surrounded by two adjacent second protrusions 112 and the support plate 110, and the third adhesive overflow groove 152 is connected to the mounting groove 140. The third adhesive overflow groove 152 may be used to contain adhesive, and since the third adhesive overflow groove 152 is connected to the mounting groove 140, when the stack 200 is to be fixed to the photovoltaic frame 100, the adhesive in the third adhesive overflow groove 152 flows into the mounting groove 140, thereby adhering and fixing the stack 200 to the photovoltaic frame 100. Furthermore, by combining the third adhesive overflow groove 152, the second adhesive overflow groove 151 and the first adhesive overflow groove 132, the adhesive capacity can be further increased, thereby improving the adhesive strength of the laminate 200 to the photovoltaic frame 100.

[0035] 7, the height of the secondary protrusions 112 protruding from the support plate 110 is 0.1 mm to 10 mm, and the distance between two adjacent secondary protrusions 112 is 0.5 mm to 10 mm. That is, 0.1 mm≦H6≦10 mm and 0.5 mm≦D2≦10 mm are satisfied, and H6 may be, for example, any of 0.1 mm, 2 mm, 5 mm, 7 mm, and 10 mm, and D2 may be any of 0.5 mm, 2 mm, 5 mm, 7 mm, and 10 mm, and the specific values ​​of H6 and D2 are not limited in the present application. In this embodiment, when the laminate 200 is attached to the photovoltaic frame 100, the backlight surface 210 of the laminate 200 is placed on the second protrusion 112, and by limiting the height of the second protrusion 112 protruding from the support plate 110 to 0.1 mm to 10 mm, it is possible to ensure that the second protrusion 112 has sufficient support strength for the laminate 200, and by limiting the distance between two adjacent second protrusions 112 to 0.5 mm to 10 mm, it is possible to ensure the structural strength of the support plate 110.

[0036] 6A , a third protrusion 113 is further provided on the end face of the support plate 110 closer to the mounting groove 140. The third protrusion 113 corresponds to the second side panel 130; that is, the third protrusion 113 is formed at the joint between the support plate 110 and the second side panel 130. The height of the third protrusion 113 is slightly greater than the height of the second protrusion 112. The second protrusion 112, the third protrusion 113, and the support plate 110 surround and form a fourth adhesive overflow groove 153 that communicates with the mounting groove 140. The combination of the fourth adhesive overflow groove 153, the third adhesive overflow groove 152, the second adhesive overflow groove 151, and the first adhesive overflow groove 132 further increases the adhesive capacity, thereby improving the adhesive strength of the laminate 200 to the photovoltaic frame 100.

[0037] It should be understood that in other embodiments, as shown in FIG. 6B, the third protrusion 113 and the fourth adhesive overflow groove 153 may be omitted.

[0038] 8 , in one embodiment, adhesive overflow plate 131 includes adhesive receiving portion 1311 and support portion 1312 formed by bending an end of adhesive receiving portion 1311, and the side of adhesive receiving portion 1311 away from support portion 1312 is connected to second side panel 130, i.e., one side of adhesive receiving portion 1311 is connected to second side panel 130, and the other side of adhesive receiving portion 1311 is connected to support portion 1312. Adhesive receiving portion 1311 protrudes in a direction away from first side panel 120, and support portion 1312 extends in the protruding direction of protruding portion 121, i.e., support portion 1312 may protrude vertically or approximately vertically in the plane of the drawing, and adhesive receiving portion 1311 may be provided horizontally or at an angle on second side panel 130. 5 , if the angle between the adhesive reservoir 1311 and the second side panel 130 is defined as β, the angle satisfies 0<β≦90°, and β may be, for example, 15°, 30°, 45°, 60°, 75°, or 90°; the specific value of β is not limited by the present application. The support 1312, the second side panel 130, and the adhesive reservoir 1311 surround and form a first adhesive overflow groove 132. The first adhesive overflow groove 132 is used to accommodate adhesive. In combination with the adhesive groove structure 150, this increases the adhesive capacity, improving the adhesive strength of the laminate 200 to the photovoltaic frame 100. Furthermore, the first adhesive overflow groove 132 accommodates adhesive spilling from the adhesive groove structure 150, preventing the adhesive from spilling onto the backlight surface 210 of the laminate 200.

[0039] Furthermore, when the laminate 200 is attached to the photovoltaic frame 100, the backlight surface 210 of the laminate 200 abuts the end of the support portion 1312 that is away from the adhesive accommodating portion 1311, and the support portion 1312 can support the laminate 200 attached to the photovoltaic frame 100, effectively preventing problems such as deformation or even breakage during the process of the photovoltaic frame 100 fixing the laminate 200 over a long period of time, and improving the service life of the photovoltaic frame 100.

[0040] 2, 3, and 8, the photovoltaic frame 100 further includes a reinforcing plate 170, the two sides of which are connected to the second side panel 130 and the surface of the adhesive receiving portion 1311 opposite the mounting groove 140, respectively, and are used to support the adhesive overflow plate 131. Generally, to increase the adhesive capacity of the first adhesive overflow groove 132, the adhesive receiving portion 1311 extends a greater distance away from the first side panel 120. For example, in this embodiment, as shown in FIG. 4, the distance H7 that extends from the adhesive receiving portion 1311 away from the first side panel 120 satisfies the relationship 1 mm≦H7≦20 mm, and H7 may be, for example, 1 mm, 5 mm, 10 mm, 15 mm, or 20 mm. The specific value of H7 is not limited by the present application. When the backlight surface 210 of the laminate 200 abuts against the end of the support portion 1312 away from the adhesive storage portion 1311, the force applied by the laminate 200 to the adhesive overflow plate 131 increases, and the reinforcing plate 170 can improve the support strength of the adhesive overflow plate 131, thereby avoiding problems such as deformation or even breakage of the adhesive overflow plate 131 in the process of supporting the laminate 200 over a long period of time, and further improving the service life of the photovoltaic frame 100.

[0041] 2, 3, and 8, the adhesive overflow plate 131 further includes an adhesive collecting portion 1313. The adhesive collecting portion 1313 is connected to the end of the support portion 1312 that is remote from the adhesive storing portion 1311, and protrudes in a direction approaching the first side plate 120. An adhesive passing opening 1314 is provided between the adhesive collecting portion 1313 and the second side plate 130, and the adhesive passing opening 1314 communicates with both the first adhesive overflow groove 132 and the mounting groove 140. During installation, when the adhesive in the adhesive groove structure 150 and the first adhesive overflow groove 132 is pressed by the laminate 200, the adhesive in the adhesive groove structure 150 passes through the adhesive passage opening 1314 and enters and is accommodated in the first adhesive overflow groove 132, and the adhesive accumulation portion 1313 ensures that the adhesive in the first adhesive overflow groove 132 is accommodated as much as possible within the first adhesive overflow groove 132, thereby preventing the adhesive in the first adhesive overflow groove 132 from subsequently spilling onto the backlight surface 210 of the laminate 200 while under pressure.

[0042] 2, 3, 9, and 10, the photovoltaic frame 100 further includes a position restriction plate 160. The position restriction plate 160 is provided at an end extending in the longitudinal direction of the photovoltaic frame 100, that is, at an end of the photovoltaic frame 100 extending in a direction perpendicular to the plane of the paper as shown in Fig. 2, and the position restriction plate 160 has an abutment surface 161. When the laminate 200 is attached to the photovoltaic frame 100, two adjacent side walls of the laminate 200 face the protruding portion 121 and the abutment surface 161, respectively.

[0043] Among these, if a deviation occurs in the relative position between the laminate 200 and the photovoltaic frame 100 during the assembly process of the laminate 200 and the photovoltaic frame 100, the laminate 200 will be attached to the photovoltaic frame 100 with a deviation. Furthermore, since the laminate 200 is attached and fixed to the photovoltaic frame 100 by adhesive bonding, it becomes difficult to adjust the relative position between the laminate 200 and the photovoltaic frame 100. If the position of the laminate 200 is forcibly adjusted, the laminate 200 is likely to be damaged, and the internal structure of the adhesive layer 300 will be destroyed, reducing the adhesive performance of the adhesive layer 300. In the photovoltaic frame 100 of the present application, when the laminate 200 is to be attached to the photovoltaic frame 100, the position control plate 160 determines the attachment position of the laminate 200 relative to the photovoltaic frame 100 so that the two adjacent side walls of the laminate 200 face the protrusion 121 and the abutment surface 161, respectively, thereby ensuring the accuracy of the attachment position of the laminate 200 and the photovoltaic frame 100.

[0044] 2, 3, 9, and 10, the first side panel 120, the second side panel 130, and the support panel 110 are all configured to extend longitudinally along the longitudinal direction of the photovoltaic frame 100, and as shown in Fig. 2, the first side panel 120, the second side panel 130, and the support panel 110 all extend perpendicular to the plane of the paper. In one embodiment, there is only one positioning plate 160, and it is disposed on the side of the first side panel 120 close to the end of the first side panel 120 in its extension direction. For example, the positioning plate 160 is connected to the first side panel 120 and extends toward the inside of the adhesive groove structure 150 in a direction perpendicular to the extension direction of the first side panel 120. In another embodiment, there is only one position restriction plate 160, and it is arranged on a side of the support plate 110 close to the end in the extension direction thereof. For example, the position restriction plate 160 is connected to the support plate 110 and protrudes toward the inside of the adhesive groove structure 150 along the extension direction of the first side panel 120. In either of the above arrangement methods, because there is only one position restriction plate 160, the combination of the position restriction plate 160 and the protruding portion 121 restricts the position of only one corner of the laminate 200. This ensures the accuracy of the attachment position between the laminate 200 and the photovoltaic frame 100, and also prevents problems such as the laminate 200 jamming during attachment and not being able to fit into the photovoltaic frame 100. Furthermore, since the position control plate 160 is installed to cover the end of the adhesive groove structure 150 along the longitudinal direction of the photovoltaic frame 100, when the adhesive in the adhesive groove structure 150 is pressed by the laminate 200 during installation and the adhesive in the adhesive groove structure 150 spills out, the position control plate 160 prevents the adhesive in the adhesive groove structure 150 from spilling out from the end of the adhesive groove structure 150 to the outside, and ensures that the laminate 200 is adhered with sufficient adhesive, which further improves the adhesive strength of the adhesive to the laminate 200 and also ensures the appearance performance of the laminate 200 after installation.

[0045] Specifically, when attaching the stack 200 to the photovoltaic frame 100, first, the stack 200 and / or the photovoltaic frame 100 are moved so that the stack 200 and the photovoltaic frame 100 move in a direction that brings them closer to each other, then the relative position of the stack 200 to the photovoltaic frame 100 is determined by the first side plate 120 and the position control plate 160 so that the two adjacent side walls of the stack 200 face the protrusion 121 and the abutment surface 161, respectively, and finally, after the adhesive has hardened and an adhesive layer 300 has been formed, the attachment and fixing of the stack 200 to the photovoltaic frame 100 is complete.

[0046] It should be noted that the angular relationship between the abutment surface 161 of the position control plate 160 and the surface of the protrusion 121 closer to the adhesive groove structure can be set according to the angular relationship between the adjacent side walls of the laminate 200, and if the adjacent side walls of the laminate 200 are perpendicular to each other, then the abutment surface 161 of the position control plate 160 and the surface of the protrusion 121 closer to the adhesive groove structure 150 will also be perpendicular to each other.

[0047] In one embodiment, as shown in FIGS. 2 to 4, the photovoltaic frame 100 further includes a bottom plate 180, and the bottom plate 180 and the support plate 110 are spaced apart in a first direction (the X direction shown in FIGS. 2 and 4). The first side panel 120 is connected to the bottom panel 180 and the support panel 110, and the end of the first side panel 120 extends from the support panel 110 in a first direction to form an extension 121. The second side panel 130 and the first side panel 120 are spaced apart in a second direction (the Y direction shown in Figures 2 and 4). The second side panel 130 is connected between the bottom panel 180 and the support panel 110. That is, the bottom panel 180, the support panel 110, the first side panel 120, and the second side panel 130 form a frame structure. When the stack 200 is attached to the photovoltaic frame 100, the support panel 110, the first side panel 120, and the second side panel 130 can support the stack 200. The bottom panel 180 can be attached and connected to another structure to connect the stack 200 to the other structure. The bottom plate 180, the support plate 110, the first side plate 120, and the second side plate 130 surround and form a cavity 190, and the bottom plate 180, the support plate 110, the first side plate 120, and the second side plate 130 are connected together by corner connectors, which allow the corner connectors to lock in the cavity 190, thereby facilitating a fixed connection between the bottom plate 180, the support plate 110, the first side plate 120, and the second side plate 130.

[0048] In this embodiment, the first direction and the second direction are perpendicular to each other, but in other possible embodiments, the first direction and the second direction may form other angles.

[0049] 2 and 3, the present application further provides a photovoltaic module 400. The photovoltaic module 400 includes a laminate 200 and a photovoltaic frame 100 configured as described above, and the laminate 200 is attached to the photovoltaic frame 100.

[0050] In the photovoltaic module 400 described above, when attaching the laminate 200 to the photovoltaic frame 100, a predetermined amount of adhesive is filled into the adhesive groove structure 150 and the first adhesive overflow groove 132, and the laminate 200 is adhesively fixed in the attachment groove 140 by the adhesive layer, thereby realizing fixed attachment of the laminate 200 to the photovoltaic frame 100 and forming the photovoltaic module 400. Furthermore, the photovoltaic frame 100 in the photovoltaic module 400 does not have an effect such as shading on the light-receiving surface 220 of the laminate 200, thereby preventing problems such as water puddles and ash accumulation on the light-receiving surface 220 of the laminate 200 and improving the power generation efficiency of the laminate 200.

[0051] The technical features of the embodiments described above can be combined in any manner, and for the sake of brevity, not all possible combinations of the technical features in the above embodiments have been described. However, as long as there is no contradiction in the combination of these technical features, it should be considered to be within the scope described in this specification.

[0052] For example, in the photovoltaic module 400 of the present application, the laminate 200 includes two long sides and two short sides, and not all of the sides necessarily need to be attached to the photovoltaic frame 100; only at least one of the sides may be attached to the above-mentioned photovoltaic frame 100.

[0053] The above examples merely illustrate some embodiments of the present application so that the technical solution of the present application can be specifically and in detail understood, and should not be understood as limiting the scope of the present invention. It should be noted that those skilled in the art can make many modifications and improvements without departing from the concept of the present application, and these are included in the scope of protection of the present application. Therefore, the scope of protection of the patent of the present application is defined by the appended claims. [Explanation of symbols]
