[0022] Photovoltaic frames require adhesives such as silicone to bond them to the photovoltaic laminates to form a whole. However, these adhesives require a long time and specific temperature and humidity conditions to cure, which reduces the production efficiency of photovoltaic modules.

[0023] To solve the above problems, refer to Figures 1-5 , Figure 1 This illustration shows a schematic diagram of the structure of the first type of photovoltaic module provided in this application after bending. Figure 2 This diagram illustrates the structure of the first type of connection component provided in an embodiment of this application.

[0024] This application provides a photovoltaic module, including a laminate body 1, a connecting component 2, and a frame 3. The connecting component 2 is connected to the edge of the laminate body 1. The connecting component 2 includes at least a protrusion 21 that extends out of the edge of the laminate body 1 along a first direction. The frame 3 is provided with a mounting cavity 31 that opens along the first direction. The laminate body 1 and the connecting component 2 are mounted in the mounting cavity 31 along the first direction. The side wall of the frame 3 is also provided with a mounting hole 32 that penetrates along the first direction. The mounting hole 32 corresponds to the protrusion 21. The protrusion 21 passes through the mounting hole 32 along the first direction, and the end of the protrusion 21 extending out of the mounting hole 32 can be bent along a second direction to form a reinforcing part 211. The second direction intersects with the first direction.

[0025] It should be understood that the connecting component 2 is connected to the edge of the laminate body 1 by adhesive bonding, which can be used to bond and fix the connecting component 2 to the edge of the laminate body 1 during lamination. The connecting component 2 includes a protrusion 21 that extends beyond the edge of the laminate body 1, and the length of the protrusion 21 extending beyond the laminate body 1 does not exceed 10mm.

[0026] The frame 3 is provided with a mounting cavity 31 that opens along a first direction. The mounting cavity 31 is used to mount the laminate body 1, and the side wall of the frame 3 is provided with a mounting hole 32 that extends along the first direction. The mounting hole 32 is used to mount the protrusion 21. During installation, the laminate body 1 and the connecting assembly 2 are inserted into the mounting cavity 31 of the frame 3 along the first direction. The end of the protrusion 21 away from the laminate body 1 simultaneously extends into and out of the mounting hole 32 along the first direction. The outgoing end is bent along a second direction to form a reinforcing part 211. The second direction intersects the first direction. In one example, the first direction is perpendicular to the second direction. The reinforcing part 211 fits against the frame 3, thereby connecting the laminate body 1 and the frame 3. The height of the reinforcing part 211 does not exceed the thickness of the laminate body 1.

[0027] This application allows the laminate body 1 to be installed within the frame 3 along a first direction. The protruding portion extending along the first direction can be simultaneously inserted into the mounting hole 32 of the frame 3 along the first direction. The end of the protruding portion 21 extending out of the mounting hole 32 can be bent along a second direction to form a reinforcing portion 211, enabling the laminate body 1 and the frame 3 to connect to each other, making installation convenient and quick. Compared to existing connections using adhesives such as silicone, this application eliminates the need to wait for adhesive curing time or set specific adhesive temperatures, improving the production efficiency of photovoltaic modules. It also eliminates the use of silicone, avoiding the environmental and human health impacts of carcinogenic substances. Furthermore, eliminating silicone prevents silicone contamination of the production line. Moreover, the frame 3 used in this application is a simple steel frame structure, requiring no precise interlocking connection, significantly reducing the manufacturing process requirements for the frame 3 and lowering its production cost.

[0028] The protrusions 21 are provided in multiple ways and are arranged at intervals along the edge direction of the frame 3. The arrangement of multiple protrusions 21 can improve the stability of the connection between the laminate body 1 and the frame 3.

[0029] In some optional embodiments, the frame 3 is provided with a clearance groove (not shown) for accommodating the reinforcing part 211. The clearance groove is located on the outside of the frame 3, and the reinforcing part 211 extends into the clearance groove, which can reduce the portion of the reinforcing part 211 protruding from the frame 3 and avoid the portion of the reinforcing part 211 protruding from the frame 3 from affecting the installation of the frame 3 and other parts. At the same time, the clearance groove can also position the reinforcing part 211, further improving the tightness of the connection between the protruding part 211 and the frame 3.

[0030] Reference Figures 1-4 In some optional embodiments, the connecting component 2 includes a first connecting portion 22 and a second connecting portion 23. The first connecting portion 22 is connected to the light-receiving surface of the laminate body 1 via a first adhesive portion (not shown in the figure); the second connecting portion 23 is connected to the backlight surface of the laminate body 1 via a second adhesive portion (not shown in the figure). The raw material thickness of the first connecting portion 22 and the second connecting portion 23 does not exceed 3 mm, and the material can be an alloy material, such as stainless steel, aluminum alloy, etc., formed using bending and cutting processes. The material of the first adhesive portion and the second adhesive portion can be a hot melt adhesive film, such as EVA, POE, etc., which is not limited in this application. The dimension of the first adhesive portion and the second adhesive portion extending inward from the laminate body 1 does not exceed 12 mm.

[0031] In some optional embodiments, the connecting assembly 2 further includes a third connecting portion 221 and a fourth connecting portion 231. The third connecting portion 221 is vertically connected to the end of the first connecting portion 22; the fourth connecting portion 231 is vertically connected to the end of the second connecting portion 23. The third connecting portion 221 and the fourth connecting portion 231 are fitted together, with one fitting to the sidewall of the laminate body 1 and the other fitting to the frame 3. Alternatively, the third connecting portion 221 or the fourth connecting portion 231 may be fitted together, with one fitting to the sidewall of the laminate body 1 and the other fitting to the frame 3. In one example, the first connecting portion 22 is bent downwards to form the third connecting portion 221, which is connected to the sidewall of the laminate body 1 via an adhesive. The second connecting portion 23 is bent upwards to form the fourth connecting portion 231, which is connected to the third connecting portion 221 via an adhesive and is fitted to the inner wall of the frame 3. In one example, the second connecting part 23 bends upward to form the fourth connecting part 231, which is connected to the side wall of the laminate body 1 by an adhesive. The first connecting part 22 bends downward to form the third connecting part 221, which is connected to the fourth connecting part 231 and the third connecting part 221 by an adhesive. The third connecting part 221 is also attached to the inner wall of the frame 3.

[0032] The provision of the third connecting part 221 and the fourth connecting part 231 increases the connection area between the connecting component 2 and the laminate body 1 and the frame 3, thereby improving the stability and tightness of the connection between the laminate body 1 and the frame 3.

[0033] In some alternative embodiments, the protrusion 21 is connected to the first connecting portion 22 or the second connecting portion 23. When the third connecting portion 221 is connected to the laminate body 1, the protrusion 21 is connected to the second connecting portion 23, and when the fourth connecting portion 231 is connected to the laminate body 1, the protrusion 21 is connected to the first connecting portion 22.

[0034] Reference Figures 1-3In some optional embodiments, a first flexible pad 4 is provided between the first connecting portion 22 and the frame 3. During installation, the first flexible pad 4 can be connected to the inner wall of the frame 3, and then the laminate body 1 and the connecting assembly 2 are inserted into the mounting cavity 31, so that the first flexible pad 4 is located between the first connecting portion 22 and the frame 3. Alternatively, the first flexible pad 4 can be connected to the first connecting portion 22 first, and then the laminate body 1, the connecting assembly 2, and the first flexible pad 4 can be inserted into the mounting cavity 31, so that the first flexible pad 4 is located between the first connecting portion 22 and the frame 3. During installation, the first flexible pad 4 will deform to facilitate installation. At the same time, the first flexible pad 4 can fill the gap between the first connecting portion 22 and the frame 3, improve the tightness of the connection between the first connecting portion 22 and the frame 3, and also increase the friction between the first connecting portion 22 and the frame 3, thereby improving the stability of the connection between the first connecting portion 22 and the frame 3.

[0035] In some optional embodiments, a second flexible pad 5 is provided between the second connecting portion 23 and the frame 3. During installation, the second flexible pad 5 can be connected to the inner wall of the frame 3, and then the laminate body 1 and the connecting assembly 2 are inserted into the mounting cavity 31, so that the second flexible pad 5 is located between the second connecting portion 23 and the frame 3. Alternatively, the second flexible pad 5 can be connected to the second connecting portion 23 first, and then the laminate body 1, the connecting assembly 2, and the second flexible pad 5 are inserted into the mounting cavity 31, so that the second flexible pad 5 is located between the second connecting portion 23 and the frame 3. During installation, the second flexible pad 5 will deform to facilitate installation. At the same time, the second flexible pad 5 can fill the gap between the second connecting portion 23 and the frame 3, improve the tightness of the connection between the second connecting portion 23 and the frame 3, and also increase the friction between the second connecting portion 23 and the frame 3, thereby improving the stability of the connection between the second connecting portion 23 and the frame 3.

[0036] In some alternative embodiments, the sum of the thicknesses of the laminate body 1, the connecting assembly 2, and the first flexible pad 4 and / or the second flexible pad 5 is greater than the opening distance of the mounting cavity 31.

[0037] In one example, when only the first flexible pad 4 is provided, the sum of the thickness of the laminate body 1, the connecting component 2 and the thickness of the first flexible pad 4 is greater than the opening distance of the mounting cavity 31. When the laminate body 1, the connecting component 2 and the first flexible pad 4 are inserted into the mounting cavity 31, the first flexible pad 4 is squeezed and deformed to facilitate insertion. After the laminate body 1, the connecting component 2 and the first flexible pad 4 are inserted into the mounting cavity 31, the first flexible pad 4 returns to its original position so that the laminate body 1, the connecting component 2 and the first flexible pad 4 can fill the mounting cavity 31, thereby improving the stability and tightness of the installation of the laminate body 1, the connecting component 2, the first flexible pad 4 and the frame 3.

[0038] In one example, when only the second flexible pad 5 is provided, the sum of the thicknesses of the laminate body 1, the connecting component 2, and the second flexible pad 5 is greater than the opening distance of the mounting cavity 31. When the laminate body 1, the connecting component 2, and the second flexible pad 5 are inserted into the mounting cavity 31, the second flexible pad 5 is squeezed and deformed to facilitate its insertion. After the laminate body 1, the connecting component 2, and the second flexible pad 5 are inserted into the mounting cavity 31, the second flexible pad 5 returns to its original position so that the laminate body 1 and the second flexible pad 5 can fill the mounting cavity 31, thereby improving the stability and tightness of the installation of the laminate body 1, the connecting component 2, the second flexible pad 5, and the frame 3.

[0039] In one example, a first flexible pad 4 and a second flexible pad 5 are provided simultaneously. When the laminate body 1, the connecting component 2, the first flexible pad 4 and the second flexible pad 5 are inserted into the mounting cavity 31, the first flexible pad 4 and the second flexible pad 5 are squeezed and deformed to facilitate insertion. After the laminate body 1, the connecting component 2, the first flexible pad 4 and the second flexible pad 5 are inserted into the mounting cavity 31, the first flexible pad 4 and the second flexible pad 5 return to their original positions so that the laminate body 1, the connecting component 2, the first flexible pad 4 and the second flexible pad 5 can fill the mounting cavity 31, thereby improving the stability and tightness of the installation of the laminate body 1, the connecting component 2, the first flexible pad 4, the second flexible pad 5 and the frame 3.

[0040] In some optional embodiments, the first flexible pad 4 and / or the second flexible pad 5 are made of rubber or foam tape. When the first flexible pad 4 and / or the second flexible pad 5 are made of rubber, installation can be assisted by an adhesive.

[0042] In some optional embodiments, multiple protrusions 21 are provided, including a first protrusion 212 and a second protrusion 213. The first protrusion 212 is connected to the first connecting portion 22, and the second protrusion 213 is connected to the second connecting portion 23. Multiple mounting holes 32 are provided, including a first hole 321 for inserting the first protrusion 212 and a second hole 322 for inserting the second protrusion 213.

[0043] The first connecting portion 22 is connected to the first protrusion 212, and the first protrusion 212 is inserted into the first hole 321, so that the first connecting portion 22 is connected to the frame 3; the second connecting portion 23 is connected to the second protrusion 213, and the second protrusion 213 is inserted into the second hole 322, so that the second connecting portion 23 is connected to the frame 3. The arrangement of the first protrusion 212 and the second protrusion 213 can further improve the tightness and stability of the connection between the connecting component 2 and the frame 3, thereby improving the tightness and stability of the connection between the laminate body 1 and the frame 3.

[0044] Reference Figure 9 and Figure 10 In some optional embodiments, the photovoltaic module further includes a third flexible pad 6, which is U-shaped and used to wrap the edge of the laminate body 1. The third flexible pad 6 is provided with a connecting hole 61 through which the first protrusion 212 and the second protrusion 213 pass. The third flexible pad 6 wraps and protects the edge of the laminate body 1. During installation, the third flexible pad 6 can first wrap the laminate body 1 and the connecting component 2, or it can first be placed into the mounting cavity 31 of the frame 3. In one example, the third flexible pad 6 can first wrap the laminate body 1 and the connecting component 2. When the third flexible pad 6, the connecting component 2 and the laminate body 1 extend into the mounting cavity 31 of the frame 3, the third flexible pad 6 deforms to facilitate smooth insertion. After insertion, the third flexible pad 6 returns to its original position, thereby filling the mounting cavity 31 and improving the tightness and stability of the connection between the laminate body 1 and the frame 3.

[0045] In some optional embodiments, the sum of the thicknesses of the third flexible pad 6, the connecting component 2, and the laminate body 1 is greater than the opening distance of the mounting cavity 31. When the third flexible pad 6 is located between the frame 3 and the connecting component 2, it can further fill the gap in the mounting cavity 31, thereby further improving the tightness and stability of the connection between the laminate body 1 and the frame 3.

[0046] In some alternative embodiments, the third flexible pad 6 is made of rubber or foam tape. When the third flexible pad 6 is made of rubber, an adhesive is also required for installation.
