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.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] See Figures 1 to 5 As shown, this application embodiment provides a photovoltaic module 10, including a laminate 11, at least two first frames 12, and at least one reinforcing member 13; at least two first frames 12 are disposed opposite each other on both sides of the laminate 11 along a first direction X; each first frame 12 includes a first mounting portion 121 and a first main body portion 122; the first mounting portion 121 is disposed on one side of the first main body portion 122 along a second direction Z, and the first mounting portion 121 is connected to the laminate 11; the first main body portion 122 is provided with a first receiving groove 122a on one side along the first direction X, and a snap-fit ​​member 14 is disposed in the first receiving groove 122a; at least one reinforcing member 13 is located between at least two first frames 12; the end of the reinforcing member 13 is disposed in the first receiving groove 122a, and the reinforcing member 13 is snap-fitted with the snap-fit ​​member 14; the first direction X is parallel to the laminate 11, and the second direction Z is perpendicular to the laminate 11.

[0053] Specifically, the laminate 11 may have a rectangular structure. The laminate 11 may include a first substrate, an intermediate layer, and a second substrate stacked sequentially. The first substrate may be glass, and the second substrate may also be glass. The intermediate layer includes a first encapsulant film, a battery cell, and a second encapsulant film stacked sequentially. The materials used for the first and second encapsulant films include, but are not limited to: ethylene-vinyl acetate copolymer (EVA), polyolefin elastomer (POE), polyvinyl butyral (PVB), EPE (EVA-POE-EVA), EP (EVA-POE), or PEP (POE-EVA-POE). The types of battery cells include, but are not limited to: passivated emitter rear cell (PERC), tunnel oxide passivated contact cell (TOPCon), intrinsic thin-film heterojunction cell (HJT), interdigitated back contact cell (IBC), perovskite cell, etc.

[0054] See Figure 1As shown, the photovoltaic module 10 includes at least one reinforcing member 13. Specifically, the photovoltaic module 10 may include two reinforcing members 13, which are located between two first frame members 12 disposed opposite each other along the first direction X, and spaced apart along the third direction Y. This improves the structural strength and stability of the first frame members 12 around the laminate 11, thereby improving the structural stability and reliability of the photovoltaic module 10. Of course, the number of reinforcing members 13 can be set according to the specifications of the laminate 11, and this application does not limit this. It should be noted that the first direction X may be the width direction of the laminate 11, and the third direction Y may be the length direction of the laminate 11.

[0055] The photovoltaic module 10 provided in this application embodiment has at least two first frame frames 12 disposed opposite each other on both sides of the laminate 11 along the first direction X. The first mounting portion 121 of the first frame frame 12 is connected to the laminate 11. The first main body portion 122 of the first frame frame 12 has a first receiving groove 122a on one side along the first direction X, and a snap-fit ​​member 14 is disposed in the first receiving groove 122a. At least one reinforcing member 13 is located between at least two first frame frames 12. The end of the reinforcing member 13 is disposed in the first receiving groove 122a, and the reinforcing member 13 is snap-fitted with the snap-fit ​​member 14. In this way, the reinforcing member 13 is snap-fitted and fixed in the first receiving groove 122a by the snap-fit ​​member 14 disposed in the first receiving groove 122a. This achieves a reliable connection between the reinforcing member 13 and the first frame frame 12, improves the structural strength of the first frame frame 12, improves the deformation resistance of the first frame frame 12 and the laminate 11, thereby improving the structural stability and reliability of the photovoltaic module 10 and extending the service life of the photovoltaic module 10. In addition, it facilitates the disassembly and assembly of the reinforcing component 13, simplifies the assembly process of the photovoltaic module 10, and reduces the production and maintenance costs of the photovoltaic module 10.

[0056] In one embodiment, see [reference] Figure 2 and Figure 4 As shown, the first mounting portion 121 includes a first supporting portion 1211; the edge of the laminate 11 is disposed on the first supporting portion 1211; the first main body portion 122 includes a first connecting portion 1221 and a first base portion 1222; the first connecting portion 1221 connects the first supporting portion 1211 and the first base portion 1222; the first supporting portion 1211 includes a first extension portion 1211a extending out of the first connecting portion 1221 along the first direction X; the first base portion 1222 includes a second extension portion 1222a extending out of the first connecting portion 1221 along the first direction X; the first extension portion 1211a, the first connecting portion 1221 and the second extension portion 1222a together define a first receiving groove 122a.

[0057] Therefore, the first support portion 1211 includes a first protrusion 1211a extending from the first connecting portion 1221 along the first direction X; the first base portion 1222 includes a second protrusion 1222a extending from the first connecting portion 1221 along the first direction X. This allows the first protrusion 1211a, the first connecting portion 1221, and the second protrusion 1222a to jointly define the first receiving groove 122a, thus facilitating the fixing of the end of the reinforcing member 13 within the first receiving groove 122a. Furthermore, the edge of the laminate 11 is located on the first support portion 1211. The first support portion 1211 includes a first protrusion 1211a extending from the first connecting portion 1221 along the first direction X. This increases the contact area between the laminate 11 and the first mounting portion 121, thereby improving the reliability of the laminate 11's connection to the first mounting portion 121.

[0058] It should be noted that, for reference Figure 2 and Figure 4 As shown, the first mounting portion 121 further includes a first limiting portion 1212 and a second connecting portion 1213. The first limiting portion 1212 is located on the side of the first supporting portion 1211 away from the first base portion 1222. The second connecting portion 1213 connects the first limiting portion 1212 and the first supporting portion 1211. The first limiting portion 1212, the first supporting portion 1211, and the second connecting portion 1213 together define a second receiving groove 121a. The edge of the laminate 11 is located within the second receiving groove 121a, and encapsulating adhesive is provided between the groove wall of the second receiving groove 121a and the laminate 11. In this way, the connection between the laminate 11 and the first mounting portion 121 is realized, thereby achieving the encapsulation and fixation of the laminate 11 of the photovoltaic module 10.

[0059] In one embodiment, see [reference] Figure 2 As shown, the snap-fit ​​member 14 includes a first protrusion 141 provided on the side of the first protrusion 1211a near the second protrusion 1222a; the first protrusion 141 abuts against the side of the reinforcing member 13 away from the second protrusion 1222a.

[0060] Therefore, by abutting the first protrusion 141 against the side of the reinforcing member 13 away from the second protrusion 1222a, the reinforcing member 13 can be snapped and fixed in the first receiving groove 122a, thereby realizing the connection between the reinforcing member 13 and the first frame 12, improving the structural stability and reliability of the first frame 12, thereby improving the structural stability and reliability of the photovoltaic module 10 and extending the service life of the photovoltaic module 10.

[0061] In one embodiment, the first protrusion 141 extends along a third direction Y on the first extension 1211a; the third direction Y is perpendicular to the first direction X and perpendicular to the second direction Z.

[0062] Therefore, when multiple reinforcing members 13 are provided between two first frame frames 12 arranged opposite each other along the first direction X, the first protrusion 141 can simultaneously abut against one side of the second protrusion 1222a away from the multiple reinforcing members 13, thereby facilitating the fixing of the multiple reinforcing members 13 into the first receiving groove 122a, which can further improve the structural stability and reliability of the first frame frame 12, thereby improving the structural stability and reliability of the photovoltaic module 10 and extending the service life of the photovoltaic module 10.

[0063] In one embodiment, see [reference] Figure 4 As shown, the snap-fit ​​member 14 includes a first snap-fit ​​portion 142 and a second snap-fit ​​portion 143 that snap-fit ​​with each other; the first snap-fit ​​portion 142 is provided on one of the first connecting portion 1221 and the reinforcing member 13; the second snap-fit ​​portion 143 is provided on the other of the first connecting portion 1221 and the reinforcing member 13.

[0064] Therefore, through the snap-fit ​​of the first snap-fit ​​part 142 and the second snap-fit ​​part 143, the reinforcing member 13 can be easily fixed in the first receiving groove 122a, thereby improving the structural stability and reliability of the first frame 12, and thus improving the structural stability and reliability of the photovoltaic module 10 and extending the service life of the photovoltaic module 10.

[0065] In one embodiment, see [reference] Figure 4 As shown, the first snap-fit ​​portion 142 is a second protrusion 142a provided on one of the first connecting portion 1221 and the reinforcing member 13; the second snap-fit ​​portion 143 is a slot 143a provided on the other of the first connecting portion 1221 and the reinforcing member 13.

[0066] Therefore, by fitting the second protrusion 142a into the slot 143a, the reinforcing member 13 can be fixed in the first receiving slot 122a, which is convenient and simple to operate and facilitates the assembly and disassembly of the reinforcing member 13.

[0067] Further, see Figure 4 As shown, the second protrusion 142a can protrude from the first connecting portion 1221, and the slot 143a can be provided at the end of the reinforcing member 13. This facilitates the engagement of the second protrusion 142a and the slot 143a.

[0068] It should be noted that, for reference Figure 4 As shown, there can be multiple second protrusions 142a, and these protrusions 142a can be spaced apart along a third direction Y on the first connecting portion 1221. Two slots 143a can be provided at the end of the reinforcing member 13. That is, the two slots 143a on the reinforcing member 13 engage with the two second protrusions 142a on the first connecting portion 1221. This improves the reliability of the connection between the reinforcing member 13 and the first frame 12.

[0069] In one embodiment, see [reference] Figures 6 to 9 As shown, it also includes a connector 15; a fixing part 131 is provided on the reinforcing member 13, and the fixing part 131 extends along the extending direction of the reinforcing member 13; the connector 15 connects the first main body part 122 and the fixing part 131.

[0070] Therefore, by providing a fixing part 131 on the reinforcing member 13 and connecting the first main body part 122 and the mounting part with the connecting member 15, the reinforcing member 13 can be easily fixed to the first frame 12 by the connecting member 15, which can further improve the connection reliability between the reinforcing member 13 and the first frame 12, thereby improving the structural stability and reliability of the photovoltaic module 10 and extending the service life of the photovoltaic module 10.

[0071] It should be noted that, for reference Figure 9 As shown, the reinforcing member 13 is provided with a plurality of fixing parts 131. Specifically, two fixing parts 131 are provided at intervals on the reinforcing member 13, and both fixing parts 131 are connected to the first main body part 122 through the connecting part 15. In this way, the connection reliability between the reinforcing member 13 and the first frame 12 can be improved.

[0072] In one embodiment, see [reference] Figures 7 to 9 As shown, the fixing part 131 is provided with a first mounting hole 131a, which penetrates the fixing part 131 along the extension direction of the reinforcing member 13; the first main body part 122 is provided with a second mounting hole 1223, and the connecting member 15 passes through the first mounting hole 131a and the second mounting hole 1223.

[0073] Therefore, by connecting the first mounting hole 131a and the second mounting hole 1223, the reinforcing member 13 can be fixed to the first frame 12, which can further improve the connection reliability between the reinforcing member 13 and the first frame 12, thereby improving the structural stability and reliability of the photovoltaic module 10 and extending the service life of the photovoltaic module 10.

[0074] It should be noted that connector 15 can be a self-drilling screw, which avoids the cumbersome steps of pre-drilling and tapping in traditional fixing methods, further improving installation efficiency. Furthermore, during later maintenance or repair, the reinforcing rib can be easily removed from the frame simply by unscrewing the self-drilling screw, facilitating inspection and replacement of components in the photovoltaic module 10. Connector 15 can be made of stainless steel, giving it good corrosion resistance and ensuring stable fastening in various harsh environments.

[0075] In one embodiment, see [reference] Figure 9As shown, the fixing part 131 includes a first sub-part 1311 and a second sub-part 1312 spaced apart on the reinforcing member 13, with the first sub-part 1311 and the second sub-part 1312 disposed opposite to each other; the first sub-part 1311 includes a first arcuate surface 1311a disposed near the second sub-part 1312; the second sub-part 1312 includes a second arcuate surface 1312a disposed near the first sub-part 1311; the first arcuate surface 1311a and the second arcuate surface 1312a together define a first mounting hole 131a.

[0076] Therefore, when the connector 15 passes through the first mounting hole 131a, the first arc-shaped surface 1311a and the second arc-shaped surface 1312a can naturally guide the connector 15 to move towards the center of the hole, reducing the need for manual adjustment; if the connector 15 has manufacturing tolerances, the gap design of the first sub-part 1311 and the second sub-part 1312 can absorb minor deviations, preventing the connector 15 from getting stuck in the fixing part 131, thereby facilitating the assembly and disassembly of the connector 15.

[0077] In one embodiment, see [reference] Figure 9 As shown, the interior of the reinforcing member 13 is hollow, and the end of the reinforcing member 13 is open; the fixing part 131 is located inside the reinforcing member 13 and is connected to the side wall of the reinforcing member 13.

[0078] Therefore, by making the interior of the reinforcing member 13 hollow and the end of the reinforcing member 13 open, the weight of the reinforcing member 13 can be reduced; by placing the fixing part 131 inside the reinforcing member 13 and connecting it to the side wall of the reinforcing member 13, the structural strength of the reinforcing member 13 can be improved.

[0079] Further, see Figure 9 As shown, there are two fixing parts 131. The two fixing parts 131 are located inside the reinforcing member 13, and the two fixing parts 131 can be connected to the two oppositely arranged side walls of the reinforcing member 13.

[0080] In one embodiment, see [reference] Figure 2 , Figure 4 and Figure 8 As shown, the reinforcing member 13 has a connecting layer 16 on the side near the laminate 11, and the connecting layer 16 connects to the laminate 11.

[0081] Therefore, the reinforcing member 13 can uniformly transfer the load to the laminate 11 through the connecting layer 16, avoiding warping or delamination of the laminate 11 due to local stress concentration; the rigid support of the reinforcing member 13 can reduce the amplitude of the laminate 11 under dynamic load and prevent the propagation of microcracks. In addition, the reinforcing member 13 can play a "beam effect", improving the overall bending resistance of the laminate 11.

[0082] In one embodiment, see [reference] Figure 3 , Figure 5and Figure 9 As shown, the connecting layer 16 includes an adhesive portion 161 disposed on the side of the reinforcing member 13 near the laminate 11; the adhesive portion 161 is bonded to the laminate 11. Specifically, the adhesive portion 161 may be a structural adhesive.

[0083] In one embodiment, the adhesive portion 161 extends along the extension direction of the reinforcement 13.

[0084] This increases the contact area between the adhesive portion 161 and the laminate 11, thereby improving the connection reliability between the connecting layer 16 and the laminate 11.

[0085] In one embodiment, see [reference] Figure 3 , Figure 5 and Figure 9 As shown, the connecting layer 16 also includes a support portion 162; the support portion 162 is disposed on the side of the reinforcing member 13 near the laminate 11, and the side of the support portion 162 near the adhesive portion 161 is connected to the side of the adhesive portion 161 near the support portion 162; the side of the support portion 162 near the laminate 11 abuts against the laminate 11.

[0086] Therefore, before installing the reinforcing member 13, the support part 162 can be placed on the reinforcing member 13. When the reinforcing member 13 is fixed to the first frame 12, the side of the support part 162 near the laminate 11 abuts against the laminate 11. Then, structural adhesive is applied to the gap between the reinforcing member 13 and the laminate 11. Due to the setting of the support part 162, the flow range of the structural adhesive can be restricted, so that the structural adhesive is cured between the laminate 11 and the reinforcing member 13, forming an adhesive part 161 connecting the laminate 11 and the reinforcing member 13.

[0087] Furthermore, an adhesive layer is provided on the side of the support portion 162 near the reinforcing member 13, which facilitates fixing the support portion 162 to the reinforcing member 13. Specifically, the support portion 162 can be EVA adhesive with adhesive on one side.

[0088] In one embodiment, the support portion 162 extends along the extension direction of the reinforcement 13.

[0091] It should be noted that, for reference Figure 10 As shown, the second mounting portion 171 includes a second supporting portion 1711, a second limiting portion 1712, and a third connecting portion 1713. The first limiting portion 1712 is located on the side of the second supporting portion 1711 away from the second main body portion 172. The third connecting portion 1713 connects the second limiting portion 1712 and the second supporting portion 1711. The second limiting portion 1712, the second supporting portion 1711, and the third connecting portion 1713 together define a third receiving groove 171a. The edge of the laminate 11 is located in the third receiving groove 171a. Encapsulating adhesive is provided between the groove wall of the third receiving groove 171a and the laminate 11.

[0092] See Figure 10 As shown, the second main body 172 includes a fourth connecting portion 1721 and a second base portion 1722; the fourth connecting portion 1721 connects the second supporting portion 1711 and the second base portion 1722; the second supporting portion 1711 includes a third protrusion 1711a extending out of the fourth connecting portion 1721 along the first direction X; the second base portion 1722 includes a fourth protrusion 1722a extending out of the fourth connecting portion 1721 along the first direction X; the third protrusion 1711a, the fourth connecting portion 1721 and the fourth protrusion 1722a together define a fourth receiving groove 172a.
