Description

Technical Field

[0001] This application relates to the field of solar cell technology, and in particular to a photovoltaic frame and photovoltaic module. Background Technology

[0002] Photovoltaic modules are one of the core components of solar cells. A photovoltaic module typically consists of a laminate and a frame. The frame surrounds the laminate, serving to increase the strength of the photovoltaic module and further seal it.

[0003] Typically, before assembling the frame and laminate, sealant needs to be applied inside the frame. After the frame is installed onto the outer periphery of the laminate, pressing the frame allows the sealant to fill the gap between the laminate and the frame, ensuring a tight seal. However, if the pressing force is too great or too much sealant is applied, the sealant can easily overflow outside the frame, affecting the appearance of the photovoltaic module. Utility Model Content

[0004] Therefore, it is necessary to provide a photovoltaic frame and photovoltaic module to address the issue of excess adhesive in photovoltaic modules.

[0005] In a first aspect, this application provides a photovoltaic frame for surrounding a laminate. The photovoltaic frame includes a frame body, on which a support portion, a partition portion, and a blocking portion are protruding. The support portion, partition portion, and blocking portion are spaced apart and disposed on the same side of the frame body. The support portion is used to support the laminate. The partition portion is located between the support portion and the blocking portion. An adhesive groove is formed between the partition portion and the support portion. An overflow groove is formed between the partition portion and the blocking portion.

[0006] The technical solution will be further explained below:

[0007] In one embodiment, the height of the blocking portion protruding from the frame body is higher than or equal to the height of the partition portion protruding from the frame body.

[0008] In one embodiment, the blocking portion includes a first protrusion and a first extension. The first protrusion protrudes from the frame body, and the first extension is connected to the end of the first protrusion away from the frame body. One end of the first extension extends toward the support portion and is used to abut against the side of the laminate. The separating portion is located below the first extension, and the end of the separating portion away from the frame body and the first extension form an overflow port that connects the glue application groove and the overflow groove.

[0009] In one embodiment, the partition includes a second protrusion and a second extension. The second protrusion protrudes from the frame body and is used to separate the glue application groove from the glue overflow groove. The second extension is connected to one end of the second protrusion away from the frame body. One end of the second extension extends toward the support and is used to abut against the side of the laminate.

[0010] In one embodiment, the support portion includes a bearing surface for supporting the laminate, the blocking portion includes a first column, and the partition portion includes a second column; the first column and the second column extend uniformly along a plane perpendicular to the bearing surface.

[0011] In one embodiment, the end of the partition facing away from the frame body is formed with a ramp, and the height of the ramp gradually decreases along the direction from the blocking part to the supporting part.

[0012] In one embodiment, the support includes a bearing surface for supporting the laminate, wherein,

[0013] The depth direction of the overflow groove is inclined relative to the bearing surface, or the depth direction of the overflow groove is perpendicular to the bearing surface.

[0014] In one embodiment, along the depth direction of the overflow groove, the overflow groove includes an inlet section and a glue storage section connected in sequence, wherein the width of the glue storage section is greater than the width of the inlet section.

[0015] In one embodiment, the support includes a bearing surface for supporting the laminate; wherein,

[0016] The bearing surface is provided with a concave-convex portion, and the concave-convex portion has a concave-convex structure; and / or,

[0017] A blocking member is provided at the end of the bearing surface away from the overflow groove. The blocking member protrudes from the bearing surface and is used to fit and cooperate with the back of the laminate.

[0018] In one embodiment, the frame body includes a mounting wall, an outer wall connected to one end of the mounting wall, an inner wall connected to the other end of the mounting wall, and a bottom wall disposed opposite to the mounting wall and connecting the outer wall and the inner wall. The blocking portion, the partition portion, and the supporting portion all protrude from the mounting wall, and the blocking portion, the partition portion, and the supporting portion are sequentially spaced along the direction from the outer wall to the inner wall. The mounting wall, the outer wall, the inner wall, and the bottom wall together form a closed first cavity; or...

[0019] The frame body includes the mounting wall, an outer side wall connected to one end of the mounting wall, and an inner side wall connected to the other end of the mounting wall. The blocking part, the partition part, and the supporting part are all protruding from the mounting wall, and the blocking part, the partition part, and the supporting part are spaced apart sequentially along the direction from the outer side wall to the inner side wall. The mounting wall, the outer side wall, and the inner side wall surround and form a second cavity with an opening, and the opening is disposed opposite to the mounting wall.

[0020] Secondly, this application also provides a photovoltaic module, including a laminate and the aforementioned photovoltaic frame, wherein the laminate is disposed on the support portion and the laminate covers the opening of the overflow groove.

[0021] In the aforementioned photovoltaic frame and photovoltaic module, a support portion, a partition portion, and a blocking portion are protruding on the same side of the frame body. The space between the partition portion and the support portion is configured as a glue-applying groove, and the space between the partition portion and the blocking portion is configured as a glue overflow groove. This allows the glue-applying groove and the glue overflow groove to form two independent cavities separated by the partition portion. When the sealant in the glue-applying groove is squeezed and overflows, a small amount of overflow can be blocked by the partition portion, preventing further overflow. When the amount of overflow is large enough and exceeds the partition portion, the glue overflow groove located on the other side of the partition portion can contain the overflowing sealant, preventing it from continuing to overflow onto the side of the photovoltaic frame away from the laminate (i.e., the outer side of the photovoltaic frame). This reduces the glue overflow problem of the photovoltaic frame and ensures the neat appearance of the photovoltaic module. Attached Figure Description

[0036] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0037] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0038] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0039] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0040] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0041] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0042] As mentioned earlier, traditional photovoltaic (PV) modules are prone to adhesive overflow during assembly. The inventors discovered through research that this is because the frame of a traditional PV module typically has an E-side for supporting the laminate 30 and an A-side for pressing against the top of the laminate 30. The A-side and E-side are positioned opposite each other and together enclose an adhesive application area. An adhesive overflow area is formed on the A-side; that is, the overflow area and the adhesive application area are arranged vertically and located in the same cavity. During the actual assembly of the laminate 30 and the frame, the sealant 40 in the adhesive application area is easily compressed and reaches the overflow area. When the compression pressure is too high or too much adhesive is applied, the overflow area is easily filled, leading to adhesive overflow. Furthermore, to reduce dust accumulation in PV modules, some PV modules have begun to use frames without an A-side. However, while removing the A-side can reduce dust accumulation to some extent, it also removes the adhesive overflow area on the A-side, making the adhesive overflow problem even more severe.

[0043] Based on this, one embodiment of this application provides a photovoltaic frame, specifically, see [link to application]. Figures 1 to 4 One embodiment of the photovoltaic frame includes a frame body 10. A support portion 15, a partition portion 17, and a blocking portion 18 protrude from the frame body 10. The support portion 15, the partition portion 17, and the blocking portion 18 are spaced apart and disposed on the same side of the frame body 10. (Combined with...) Figure 7 The support portion 15 is used to support the laminate 30. The separator portion 17 is located between the support portion 15 and the blocking portion 18. An adhesive groove 161 is formed between the separator portion 17 and the support portion 15, and an overflow groove 162 is formed between the separator portion 17 and the blocking portion 18.

[0044] For example, see Figure 9 a. When assembling the frame body 10 and the laminate 30, the sealant 40 can be filled into the adhesive applicator 161 first. See Figure 9 b. Then, place the laminate 30 from top to bottom onto the support part 15 of the frame body 10 and make the laminate 30 cover the groove of the glue application groove 161 to complete the assembly of the laminate 30 and the frame body 10.

[0045] In the aforementioned photovoltaic frame, a support portion 15, a partition portion 17, and a blocking portion 18 are protruding from the same side of the frame body 10. The space between the partition portion 17 and the support portion 15 is configured as a glue-applying groove 161, and the space between the partition portion 17 and the blocking portion 18 is configured as an overflow groove 162. This allows the glue-applying groove 161 and the overflow groove 162 to be separated into two independent cavities by the partition portion 17. When the sealant 40 in the glue-applying groove 161 is squeezed and overflows, a small amount of overflow can be blocked by the partition portion 17, preventing further overflow. When the amount of overflow is large enough and exceeds the partition portion 17, the overflow groove 162 on the other side of the partition portion 17 can contain the overflowing sealant 40, preventing the sealant 40 from continuing to overflow onto the side of the photovoltaic frame away from the laminate 30 (i.e., the outer side of the photovoltaic frame). This reduces the overflow problem of the photovoltaic frame and ensures the clean appearance of the photovoltaic module.

[0046] Specifically, such as Figures 1 to 4 As shown, in some embodiments, the height of the blocking portion 18 protruding from the frame body 10 is higher than or flush with the height of the partition portion 17 protruding from the frame body 10. Specifically, as Figure 3 As shown, in one embodiment, the height of the blocking portion 18 is higher than the height of the separating portion 17. For example... Figure 4 As shown, in another embodiment, the height of the blocking portion 18 is flush with the height of the partition portion 17. By configuring the height of the blocking portion 18 to be higher than or flush with the height of the partition portion 17, the blocking portion 18 can block the overflowing sealant 40 before it enters the overflow groove 162, preventing the sealant 40 from overflowing too much and causing it to overflow directly onto the outside of the frame body 10.

[0047] Optionally, see Figure 1 In one embodiment, the blocking portion 18 includes a first protrusion 181 and a first extension 182. The first protrusion 181 protrudes from the frame body 10, and the first extension 182 is connected to the end of the first protrusion 181 that is away from the frame body 10. Figure 7 One end of the first extension 182 extends toward the support 15 and is used to abut against the side of the laminate 30. See also... Figure 1 The partition 17 is located below the first extension 182. The end of the partition 17 away from the frame body 10 forms an overflow port 163 between the first extension 182 and the glue application groove 161 and the overflow groove 162.

[0048] By abutting against the side of the laminate 30, the first extension 182 and the laminate 30 together seal the adhesive application tank 161. When the sealant 40 in the adhesive application tank 161 is squeezed and tends to overflow upwards, the first extension 182 can cooperate with the laminate 30 to prevent the sealant 40 from overflowing further upwards. Furthermore, the first extension 182 can guide the overflowing sealant 40 from the overflow port 163 into the overflow tank 162, preventing the sealant 40 in the adhesive application tank 161 from overflowing onto the front of the laminate 30. In addition, by abutting against the side of the laminate 30, the first extension 182 can be positioned for installation, ensuring that the laminate 30 is accurately placed in the appropriate position on the support 15.

[0049] For example, the first protrusion 181 can be a vertical protrusion extending from the frame body 10, or it can be an irregular structure including multiple bent sections; there are no limitations here. Further, such as... Figure 1 As shown, one end of the first extension 182 away from the laminate 30 may protrude from the first protrusion 181 in the direction away from the laminate 30, so that the upper end of the blocking part 18 has an overall T-shaped structure. In other embodiments, one end of the first extension 182 away from the laminate 30 may also be directly connected to the first protrusion 181, so that the upper end of the blocking part 18 has an overall inverted L-shaped structure, which is not limited here.

[0050] See also Figure 1 Optionally, the end of the partition 17 opposite to the frame body 10 has a ramp surface 173, and the height of the ramp surface 173 gradually decreases along the direction from the snap-fit ​​portion to the support portion 15. Specifically, when the sealant 40 overflows upward from the glue applicator 161, the ramp surface 173 can guide the overflowing sealant 40 from the overflow port 163 into the overflow groove 162, preventing the sealant 40 from overflowing further. Exemplarily, in one embodiment, the ramp surface 173 can be an inclined straight surface; in another embodiment, the ramp surface 173 can also be an arc-shaped surface.

[0051] See Figure 2 In another embodiment, the separator 17 includes a second protrusion 171 and a second extension 172. The second protrusion 171 protrudes from the frame body 10 and is used to separate the glue application groove 161 and the overflow groove 162. The second extension 172 is connected to the end of the second protrusion 171 that is away from the frame body 10. Figure 8One end of the second extension 172 extends toward the support portion 15 and is used to abut against the side of the laminate 30. Similarly, by abutting against the side of the laminate 30, the second extension 172 and the laminate 30 can jointly seal the adhesive application tank 161. When the sealant 40 in the adhesive application tank 161 is squeezed and overflows upward, the second extension 172 can cooperate with the laminate 30 to prevent the sealant 40 from overflowing upward. When some of the sealant 40 enters between the second extension 172 and the side of the laminate 30, the second extension 172 can also guide the overflowing sealant 40 along the second extension 172 into the overflow tank 162, preventing the sealant 40 in the adhesive application tank 161 from overflowing upward onto the front of the laminate 30. Furthermore, by abutting against the side of the laminate 30 through the second extension 172, the laminate 30 can also be positioned for installation, ensuring that the laminate 30 can be accurately placed in the appropriate position on the support 15.

[0052] For example, such as Figure 2 As shown, the second protrusion 171 may be inclinedly disposed on the frame body 10. In another embodiment, the second protrusion 171 may be vertically disposed on the frame. Of course, the second protrusion 171 may also be other irregular structures, which are not limited here.

[0053] See also Figure 2 The end of the second extension 172 that abuts against the laminate 30 may also be provided with a ramp surface 173. When some of the sealant 40 enters between the second extension 172 and the side of the laminate 30, the ramp surface 173 can guide the overflowing sealant 40 along the second extension 172 into the overflow groove 162. Exemplarily, in one embodiment, the ramp surface 173 can be an inclined straight surface; in another embodiment, the ramp surface 173 can also be an arc-shaped surface. The arc-shaped ramp surface 173 can better fit the arc-shaped side of the laminate 30, improving the positioning effect of the laminate 30.

[0054] See Figure 3 as well as Figure 4 In other embodiments, the blocking portion 18 includes a first post 184, and the separating portion 17 includes a second post 174, with the first post 184 and the second post 174 arranged parallel to each other. For example, as... Figure 3 As shown, in one embodiment, the support portion 15 includes a bearing surface 151 for supporting the laminate 30, and the extending directions of the first column 184 and the second column 174 are both perpendicular to the plane containing the bearing surface 151. By configuring both the blocking portion 18 and the partition portion 17 as columns, demolding is facilitated when the blocking portion 18 and the partition portion 17 are formed using extrusion molding or injection molding processes, thereby reducing the difficulty and cost of the manufacturing process.

[0055] See Figure 2 Optionally, in one embodiment, the depth direction of the adhesive overflow groove 162 is inclined relative to the bearing surface 151. The inclined adhesive overflow groove 162 can increase the depth of the adhesive overflow groove 162 in a limited space, thereby increasing the amount of adhesive overflow that the adhesive overflow groove 162 can hold, and further preventing the sealant 40 from overflowing outside the photovoltaic frame. See also Figure 3 In other embodiments, the depth direction of the overflow groove 162 may also be perpendicular to the bearing surface 151, thereby facilitating molding.

[0056] See Figure 2 Optionally, in one embodiment, along the depth direction of the overflow groove 162, the overflow groove 162 includes an inlet section 1621 and a storage section 1622 connected in sequence, the width of the storage section 1622 being greater than the width of the inlet section 1621. Thus, when the sealant 40 enters the overflow groove 162, the sealant 40 will flow from the inlet section 1621 into the storage section 1622 under the influence of gravity. By configuring the width of the storage section 1622 to be greater than that of the inlet section 1621, the storage section 1622 can accommodate more sealant 40, thereby increasing the amount of overflow that the overflow groove 162 can hold.

[0057] For example, see Figure 1 In one embodiment, the extension direction of the entry segment 1621 may be perpendicular to the plane containing the bearing surface 151, see [reference]. Figure 2 In another embodiment, the extension direction of the entry segment 1621 may also be inclined relative to the bearing surface 151.

[0058] Furthermore, the shape of the adhesive storage segment 1622 is not limited; for example, such as... Figure 6 a and Figure 6 As shown in d, the shape of the adhesive storage section 1622 can be rectangular or square, for example... Figure 6 As shown in b, the shape of the adhesive storage section 1622 can be circular or elliptical; for example... Figure 6 As shown in e, the shape of the adhesive storage section 1622 can also be a triangle, etc., and there are no restrictions here.

[0059] See Figure 1In one embodiment, the bearing surface 151 of the support portion 15 is provided with a concave-convex portion 152, which has a concave-convex structure. The concave-convex portion 152 increases the friction between the bearing surface 151 and the laminate 30, thereby enhancing the stability of the laminate 30. Simultaneously, when the sealant 40 overflows inward between the bearing surface 151 and the laminate 30, the concave-convex portion 152 can accommodate a portion of the sealant 40. After the sealant 40 cures, it can bond the bearing surface 151 and the laminate 30, improving the connection stability between them. Furthermore, the concave-convex portion 152 can also impede the flow of the sealant 40, reducing the overflow of sealant 40 onto the back side of the laminate 30. Exemplarily, the concave-convex portion 152 includes multiple grooves, which are spaced apart along a direction away from the adhesive application groove 161.

[0060] Furthermore, a blocking member 153 is provided at the end of the bearing surface 151 away from the adhesive overflow groove 162. The blocking member 153 protrudes from the bearing surface 151 and is used to fit against the back side of the laminate 30. Exemplarily, the blocking member 153 is located on the side of the protrusion 152 away from the adhesive coating groove 161. By fitting the blocking member 153 against the back side of the laminate 30, the sealant 40 can be further prevented from overflowing onto the back side of the laminate 30. Exemplarily, the blocking member 153 includes an adhesive component, which can be a cured adhesive. The adhesive component can fit more tightly against the back side of the laminate 30, preventing adhesive overflow.

[0061] See Figure 1 In one embodiment, the frame body 10 includes a mounting wall 11, an outer wall 12 connected to one end of the mounting wall 11, an inner wall 13 connected to the other end of the mounting wall 11, and a bottom wall 14 disposed opposite to the mounting wall 11 and connecting the outer wall 12 and the inner wall 13. A blocking portion 18, a partition portion 17, and a supporting portion 15 all protrude from the mounting wall 11, and the blocking portion 18, the partition portion 17, and the supporting portion 15 are spaced apart sequentially along the direction from the outer wall 12 to the inner wall 13. The mounting wall 11, the outer wall 12, the inner wall 13, and the bottom wall 14 together form a closed first cavity 191. The first cavity 191 can reduce the material cost of the frame body 10 and also reduce the weight of the frame body 10, facilitating the handling and installation of the frame body 10.

[0062] See Figure 5In another embodiment, the frame body 10 includes a mounting wall 11, an outer side wall 12 connected to one end of the mounting wall 11, and an inner side wall 13 connected to the other end of the mounting wall 11. A blocking portion 18, a separating portion 17, and a supporting portion 15 all protrude from the mounting wall 11, and are spaced apart sequentially along the direction from the outer side wall 12 to the inner side wall 13. The mounting wall 11, the outer side wall 12, and the inner side wall 13 form a second cavity 192 with an opening 193, which is opposite to the mounting wall 11. The second cavity 192 also reduces the material cost and weight of the frame body 10. Furthermore, when photovoltaic modules need to be installed on a crossbeam, the crossbeam can be directly inserted into the second cavity 192 using the opening 193, thus fixing the frame to the crossbeam without the need for clamps, simplifying the photovoltaic module installation process and improving installation efficiency.

[0063] See Figure 6 c. Optionally, in one embodiment, the side of the blocking portion 18 away from the partition portion 17 is flush with the outer wall 12 of the frame body 10, thus ensuring that the frame has a flat and beautiful appearance.

[0064] See Figure 6 b. In another embodiment, the side of the blocking portion 18 away from the partition portion 17 protrudes from the outer wall 12 of the frame body 10, that is, the outer wall 12 of the frame body 10 is recessed inward relative to the blocking portion 18, so that the outer wall 12 of the frame body 10 can be closer to the center of gravity of the mounting wall 11, so that the outer wall 12 can better support the mounting wall 11 and the structure on the mounting wall 11, thereby improving the stability of the photovoltaic module.

[0065] See Figure 7 as well as Figure 8 This application also provides a photovoltaic module in one embodiment. The photovoltaic module of one embodiment includes a laminate 30 and a photovoltaic frame of any of the above embodiments. The laminate 30 is disposed on the support portion 15 and covers the groove opening of the overflow groove 162.

[0066] In the photovoltaic frame of the aforementioned photovoltaic module, a support portion 15, a partition portion 17, and a blocking portion 18 are protruding on the same side of the frame body 10. The space between the partition portion 17 and the support portion 15 is configured as a glue-applying groove 161, and the space between the partition portion 17 and the blocking portion 18 is configured as an overflow groove 162. In this way, the glue-applying groove 161 and the overflow groove 162 can be separated by the partition portion 17 to form two independent cavities. When the laminate 30 is placed on the support portion 15, causing the sealant 40 in the glue-applying groove 161 to be squeezed, a small amount of overflow can be blocked by the partition portion 17 to prevent the overflow from continuing to spill outward. When the amount of overflow is large enough and exceeds the partition portion 17, the overflow groove 162 located on the other side of the partition portion 17 can contain the overflowed sealant 40, preventing the sealant 40 from continuing to spill to the side of the photovoltaic frame away from the laminate 30 (i.e., the outer side of the photovoltaic frame), thereby reducing the problem of overflow in the photovoltaic frame and ensuring the clean appearance of the photovoltaic module.

[0067] See Figure 7 as well as Figure 8 Optionally, in one embodiment, to improve the connection stability between the frame body 10 and the laminate 30, the photovoltaic frame may further include a limiting member 20. The limiting member 20 engages with the frame body 10 and is used to engage with the side of the laminate 30, thereby limiting the laminate 30 in the thickness direction and preventing the laminate 30 from detaching upward from the photovoltaic frame. Furthermore, in the thickness direction of the laminate 30, the limiting member 20 is lower than or flush with the front surface of the laminate 30, thereby preventing the limiting member 20 from obstructing the front surface of the laminate 30. This ensures that dust falling onto the front surface of the laminate 30 can be quickly washed away by rainwater, thus ensuring the structural stability of the photovoltaic module while reducing dust accumulation on the front surface of the photovoltaic module and improving the power generation efficiency of the photovoltaic module.

[0068] Further, see Figure 8 In one embodiment, the limiting member 20 can be directly snapped into the glue overflow groove 162 of the frame body 10, thereby achieving the connection and fixation between the limiting member 20 and the frame body 10. At this time, the buckle can be inserted into the glue overflow groove 162 from top to bottom along the depth direction of the glue overflow groove 162 to install the limiting member 20 onto the frame body 10.

[0069] See Figure 7 In another embodiment, a slot 183 may be formed on the side of the blocking portion 18 away from the partition portion 17, and the limiting member 20 may be engaged in the slot 183 and abut against the side of the laminate 30. In this case, the limiting member 20 may be horizontally inserted into the slot 183 in the direction from the blocking portion 18 to the partition portion 17, so as to install the limiting member 20 onto the frame body 10.

[0070] Optionally, in one embodiment, the assembly method of the photovoltaic module includes the following steps:

[0071] S110: See also Figure 9 a. Fill the glue application groove 161 of the frame body 10 with sealant 40.

[0072] S120: See also Figure 9 b. Place the laminate 30 on the support 15 from top to bottom;

[0073] S130: See also Figure 9 c. Install the limiting member 20 onto the frame body 10 and make the limiting member 20 cooperate with the side limiting of the laminate 30.

[0074] Specifically, in the traditional photovoltaic module assembly process, the laminate 30 usually needs to be inserted laterally between the A and E sides of the frame. During this process, the laminate 30 or the frame is easily squeezed and cracked. However, the main method of this application for photovoltaic modules avoids squeezing the laminate 30 during assembly by placing it from top to bottom on the support portion 15 of the frame, reducing the risk of cracking and improving the ease of placement. After the laminate 30 is placed on the support portion 15, the side of the laminate 30 is limited by the limiting member 20, effectively improving the installation stability of the laminate 30 and preventing it from detaching from the photovoltaic frame.

[0075] 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.

[0076] 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 protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
