[0002] The cavity in the frame of the photovoltaic module is prone to water accumulation, and a drainage hole is usually processed at the bottom of the cavity to drain the water in the cavity. In the related art, the drainage hole is usually a stamping design, but there is no support for the stamping surface in the cavity of the conventional frame. When the drainage hole is stamped, due to the stamping action of the stamping die, it is easy to form mechanical processing marks around the drainage hole, resulting in an inward convexity around the drainage hole, affecting the drainage effect, and then affecting the product yield. There is room for improvement. Summary of the invention

[0003] The present application aims to at least solve the technical problem of mechanical processing lines formed near the drain outlet in the related art. To this end, the present application proposes a frame that can alleviate the influence of mechanical processing lines near the drain outlet to a certain extent.

[0004] In a first aspect, the present application provides a frame, which is applied to a photovoltaic module, including:

[0005] A plurality of side beams connected end to end in sequence, wherein the side beams form a cavity, and a bottom wall of the cavity of at least one of the side beams is provided with a drainage notch at an end, and the drainage notch and an adjacent side beam form a drainage port;

[0006] An angle code is connected between two adjacent side beams and extends into the cavity. The angle code forms a water guide groove, which is connected to the drainage port.

[0007] By setting the drainage notch at the end of the bottom wall of the cavity of the side beam, a tool can be used to provide support for the stamping surface when stamping the drainage notch, thereby alleviating the influence of the machining lines near the drainage notch to a certain extent and improving the integrity of the frame structure. At the same time, the water guide groove is set on the corner code, which can be used to guide and accelerate the discharge of water accumulated inside the frame.

[0008] According to one embodiment of the present application, the corner code includes an inner plate, an outer plate, and connecting ribs connected between the inner plate and the outer plate, and the lower portions of the outer plate and the connecting ribs are provided with water guide notches to form the water guide grooves.

[0009] The corner bracket adopts the structural design of the inner plate, the outer plate and the connecting rib, which can enhance the connection strength between the corner bracket and the side beam and optimize the stress distribution. Meanwhile, by reasonably designing the structure and position of the water guide groove, the drainage efficiency of the frame can be significantly improved, the photovoltaic module can be protected from water damage, and the maintenance cost can be reduced.

[0010] According to an embodiment of the present application, the outer plate includes a first section and a second section that are bent and connected, and the water guide groove extends from an end of the first section away from the second section to an end of the second section away from the first section.

[0011] The outer plate includes the first section and the second section connected by bending, and the water guide groove extending along this path, so that the accumulated water can be smoothly discharged from the frame, reducing the risk of damage to the photovoltaic module caused by the accumulated water.

[0012] According to one embodiment of the present application, the inner side plate of the angle code is provided with a serrated structure.

[0013] By providing a serrated structure on the inner side plate, the connection strength between the angle bracket and the side beam can be enhanced.

[0014] According to one embodiment of the present application, the cross-sectional shape of the water guide groove is rectangular.

[0015] The water guide groove with a rectangular cross-section can improve drainage efficiency, resist external pressure and deformation, and reduce the influence of the groove on the structural strength of the corner code to a certain extent.

[0017] The bottom wall and the top wall of the cavity are respectively provided with the first convex rib and the second convex rib, and the corner code is clamped between the two convex ribs to achieve an interference fit with the cavity. This design can not only enhance the connection strength between the corner code and the frame, but also improve the structural stability and durability of the photovoltaic module.

[0018] According to an embodiment of the present application, the bottom wall of the cavity is provided with a first reinforcing rib, the top wall of the cavity is provided with a second reinforcing rib, the first reinforcing rib partially extends into the water guide groove, and the second reinforcing rib contacts the angle code.

[0019] The first reinforcing rib and the second reinforcing rib are respectively provided on the bottom wall and the top wall of the cavity, which can further enhance the structural strength and stability of the frame. Meanwhile, the first reinforcing rib partially extends into the water guide groove, and the second reinforcing rib is in direct contact with the corner code, which can also optimize the drainage performance of the water guide groove and improve the connection strength between the frame and the corner code.

[0021] The shape of the drain port can be selected according to the specific installation environment and drainage requirements.

[0022] According to one embodiment of the present application, the drainage gap is triangular, and the drainage outlet is triangular or rectangular.

[0023] The triangular drainage gap can take into account both the drainage function and the structural stability of the frame, which helps to enhance the overall structural strength of the frame. In addition, the triangular drainage gap is convenient for providing a support surface during stamping, which can alleviate the impact of machining marks near the drainage hole to a certain extent.

[0050] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0051] The present application aims to at least solve the technical problem of mechanical processing lines formed near the drain outlet in the related art. To this end, the present application proposes a frame that can alleviate the influence of mechanical processing lines near the drain outlet to a certain extent.

[0052] Reference below Figure 1-Figure 9 Describe the frame 1 according to the embodiment of the present application

[0053] like Figure 1-Figure 6 As shown, the frame 1 includes: a plurality of side beams 10 and corner brackets 20 connected end to end.

[0054] The frame 1 can protect the laminate of the photovoltaic module from external physical impact and damage, and can also provide necessary support for the laminate so that it can withstand external loads such as wind pressure and snow pressure to maintain the normal operation of the module.

[0055] like Figure 3 and Figure 4 As shown, a drainage notch 120 is provided at the end of the bottom wall of the cavity 110 of the side beam 10, and a drainage port 130 is formed with the adjacent side beam 10, which can effectively discharge the moisture accumulated inside the frame 1, reduce the erosion and damage of the moisture to the laminate, thereby improving the weather resistance and service life of the photovoltaic module. The drainage notch 120 is stamped.

[0056] like Figure 1 As shown, the frame 1 can form an integral structure by connecting a plurality of side beams 10 end to end in sequence, thereby enhancing its structural strength and stability, so that the frame 1 can better withstand external loads and protect the laminate from damage. In addition, through reasonable connection methods and structural designs, the installation process can be simplified, the installation cost can be reduced, and the frame 1 components can be easily disassembled and replaced.

[0057] The number of drain outlets 130 of the frame 1 can be one or more, depending on the application scenarios. For example, when the photovoltaic component is fixedly installed, one drain outlet 130 can be set, and when the photovoltaic component is rotatably installed, multiple drain outlets 130 can be set.

[0058] The fixed installation of photovoltaic modules is suitable for stable power generation scenarios. For example, fixed photovoltaic modules are usually installed on roofs, ground, walls and other locations, and are firmly fixed to the installation surface by brackets, bolts and other fixings. Fixed photovoltaic modules will not be displaced or tilted due to natural factors such as wind and rain, and the number of drainage outlets 130 is not required.

[0059] The rotating installation of photovoltaic modules is suitable for complex terrain scenarios. For example, rotating photovoltaic modules are usually installed on mountains, hills or sloping roofs. The angle and orientation of the photovoltaic modules are automatically adjusted to maximize the capture of solar radiation. The rotating photovoltaic modules are in a tilted state for a long time, and a high number of drainage outlets 130 are required to ensure smooth drainage.

[0060] For example, drainage holes 130 are provided at the connection points of the side beams 10 of the frame 1. When the photovoltaic module rotates, the connection point of the side beams 10 at the lowest point is not fixed, but each connection point of the side beams 10 is provided with a drainage hole 130, and normal drainage can be achieved through the drainage hole 130 at the lowest point.

[0061] like Figure 5As shown, the corner code 20 is a connecting piece between two adjacent side beams 10, and is mainly used to tightly connect the adjacent side beams 10 together to form a complete frame 1 structure. This connection method enables the frame 1 to jointly bear the force when subjected to external loads, thereby improving the overall rigidity and stability of the frame 1.

[0062] Extending the corner code 20 into the cavity 110 can provide additional support for the frame 1, enhance the load-bearing capacity of the frame 1, and reduce deformation or damage caused by long-term bearing of the weight of the laminate and external pressure. When the photovoltaic module is subjected to external loads, the corner code 20 can also disperse and transfer stress to various parts of the frame 1, which helps to reduce the occurrence of local stress concentration and reduce the risk of damage to the frame 1 due to excessive stress.

[0063] The corner code 20 is usually made of high-strength and corrosion-resistant materials, such as aluminum alloy or stainless steel. The good mechanical properties and weather resistance can meet the use requirements of the photovoltaic module frame 1. The corner code 20 is tightly connected and stably supported with the side beam 10 through multiple connection points and supporting surfaces.

[0064] like Figure 6 As shown, the corner code 20 forms a water channel 250 and the bottom of the water channel 250 is open, and the open bottom is connected to the drain port 130 on the frame 1, which can guide and accelerate the discharge of the accumulated water inside the frame 1. The main function of the water channel 250 is to discharge the moisture accumulated inside the cavity 110 of the frame 1. When rainwater or other liquids penetrate into the frame 1, they will first be collected by the gap between the laminate and the frame 1, and then the liquid will flow along a specially designed drainage path to the water channel 250 at the corner code 20, and be discharged to the outside of the frame 1 through the drain port 130, thereby reducing the direct contact and damage of moisture to the laminate.

[0065] In the related art, water is easily accumulated in the cavity of the frame of the photovoltaic module, and a drainage hole is usually processed at the bottom of the cavity to drain the water in the cavity. The frame is made of aluminum alloy, and the drainage hole is usually a stamping design. However, there is no support for the stamping surface in the cavity of the conventional photovoltaic frame. When punching the drainage hole, due to the stamping action of the stamping mold, mechanical processing lines are easily formed around the drainage hole, causing the periphery of the drainage hole to bulge inward, affecting the drainage effect, and further affecting the yield of the product. There is room for improvement. The present application punches a drainage notch 120 at the end of the bottom wall of the cavity 110 of the side beam 10 to solve the problem of mechanical processing lines being formed near the drainage notch 120 due to the lack of support on the stamping surface when the drainage notch 120 is stamped. A water guide groove 250 is also provided on the corner code 20 to guide and accelerate the discharge of water accumulated inside the frame 1.

[0066] According to the frame 1 provided in the embodiment of the present application, by setting the drainage gap 120 at the end of the bottom wall of the cavity 110 of the side beam 10, a tool can be used to provide support for the stamping surface when stamping the drainage gap 120, thereby alleviating the influence of the machining lines near the drainage gap 120 to a certain extent, improving the structural integrity and drainage efficiency of the frame 1, and at the same time, a water guide groove 250 is set on the corner code 20, which can be used to guide and accelerate the discharge of accumulated water inside the frame 1.

[0067] In some embodiments, Figure 7 and Figure 8 As shown, the angle code 20 includes an inner plate 210, an outer plate 220 and a connecting rib 230 connected between the inner plate 210 and the outer plate 220. The inner plate 210 of the angle code 20 is provided with a serrated structure, and the lower parts of the outer plate 220 and the connecting rib 230 are provided with a water guide notch 240 to form a water guide groove 250.

[0068] The inner plate 210, the outer plate 220 and the connecting rib 230 together constitute the main supporting structure of the angle bracket 20, which can provide sufficient strength and rigidity for the angle bracket 20, and can also enable the angle bracket 20 to maintain a stable shape and size when connected to the side beam 10. The inner plate 210 and the outer plate 220 are both close to the side wall of the cavity 110 of the side beam 10 to provide support and fixation. The design of the connecting rib 230 helps to optimize the stress distribution inside the angle bracket 20. When subjected to external loads, the connecting rib 230 can disperse the stress to the entire structure of the angle bracket 20, reduce the occurrence of local stress concentration, and thus improve the durability and service life of the angle bracket 20.

[0069] The serrated structure on the inner plate 210 can increase the friction of the contact surface between the corner bracket 20 and the side beam 10, thereby improving the connection strength between the corner bracket 20 and the side beam 10, so that the corner bracket 20 can be more firmly fixed on the side beam 10 when subjected to external loads, reducing the risk of loosening or falling off. The serrated structure also has a certain elastic deformation ability, which can absorb and disperse vibration energy to a certain extent, thereby improving the seismic performance of the frame 1 and reducing damage to the frame 1 and the risk of falling off of the laminate.

[0070] A water guiding notch 240 is provided at the lower part of the outer plate 220 and the connecting rib 230, and a plurality of water guiding notches 240 are interconnected to form a water guiding groove 250. When rainwater or other liquid penetrates into the interior of the frame 1 through the gap between the frame 1 and the laminate, it can enter the water guiding notch 240 along a specific path, flow along the path of the water guiding groove 250, and finally be discharged to the outside of the frame 1 through the drain port 130.

[0071] The angle bracket 20 can form a stable support structure by closely combining the inner plate 210, the outer plate 220 and the connecting rib 230, thereby enhancing the overall strength of the frame 1. The water guide notch 240 is arranged on the angle bracket 20 to form a water guide groove 250, so that the accumulated water inside the frame 1 can be discharged more smoothly, thereby reducing the risk of damage to the photovoltaic module caused by water immersion.

[0072] It can be understood that the angle code 20 adopts the structural design of the inner plate 210, the outer plate 220 and the connecting rib 230, and a serrated structure is provided on the inner plate 210, which can enhance the connection strength between the angle code 20 and the side beam 10, and can also optimize the stress distribution. At the same time, by reasonably designing the structure and position of the water guide groove 250, the drainage efficiency of the frame 1 can be significantly improved, the photovoltaic modules can be protected from water damage, and the maintenance cost can be reduced.

[0073] In some embodiments, Figure 7 As shown, the outer plate 220 includes a first section 221 and a second section 222 that are bent and connected, and the water guide groove 250 extends from an end of the first section 221 away from the second section 222 to an end of the second section 222 away from the first section 221 .

[0074] The outer plate 220 includes a first section 221 and a second section 222 that are bent and connected to each other, which can improve the structural stability. The bending angles and positions of the first section 221 and the second section 222 can be adjusted according to actual needs to adapt to the requirements of different sizes and shapes of the frame 1. The water guide groove 250 starts from the end of the first section 221 of the outer plate 220 that is away from the second section 222 and extends to the end of the second section 222 that is away from the first section 221. This extension path can make the accumulated water flow smoothly along the water guide groove 250 and finally be discharged from the outside of the frame 1. The width, depth and shape of the water guide groove 250 can be designed as needed to optimize the drainage performance and structural strength.

[0075] When rainwater or other liquids penetrate into the frame 1 of the photovoltaic module, the liquid will flow along a specially designed drainage path to the corner code 20, and the accumulated water will first be guided into the end of the first section 221 away from the second section 222 or the end of the second section 222 away from the first section 221, and then the accumulated water will flow along the path of the water guide groove 250, and will be discharged from the frame 1 through the drainage port 130 connected to the water guide groove 250 at the bend between the first section 221 and the second section 222.

[0076] It is understandable that the outer plate 220 includes a first section 221 and a second section 222 connected by a bend, and a water guide groove 250 extending along this path, so that the accumulated water can be smoothly discharged from the frame 1, reducing the risk of damage to the photovoltaic module caused by the accumulated water.

[0077] In some embodiments, Figure 8As shown, the cross-sectional shape of the water channel 250 is rectangular.

[0078] The rectangular cross-sectional shape can provide a larger water flow channel area, so that the accumulated water can be discharged from the outside of the frame 1 more quickly through the water guide groove 250, thereby reducing the resistance and residence time of the water flow in the water guide groove 250 and improving the drainage efficiency. In addition, the rectangular geometric shape has good stability and rigidity, can resist external pressure and deformation, and to a certain extent reduce the impact of the grooving on the structural strength of the diagonal code 20.

[0079] At the same time, the rectangular cross-section water guide groove 250 is relatively simple and easy to produce by machining or mold forming. Its simple structure is also convenient for subsequent maintenance and cleaning, which can reduce maintenance costs and difficulties. The rectangular water guide groove 250 can also be customized according to the specific size and drainage requirements of the frame 1. The width, depth and length can be adjusted as needed to meet the drainage requirements of different photovoltaic module frames 1.

[0080] It can be understood that the water guide groove 250 with a rectangular cross-section can improve the drainage efficiency, resist external pressure and deformation, and reduce the impact of the groove on the structural strength of the corner code 20 to a certain extent.

[0081] In some embodiments, Fig. 9 As shown, the bottom wall of the cavity 110 is provided with a first convex rib 151 , the top wall of the cavity 110 is provided with a second convex rib 152 , and the angle code 20 is clamped between the first convex rib 151 and the second convex rib 152 to have an interference fit with the cavity 110 .

[0082] The first convex rib 151 and the second convex rib 152 serve as positioning and fixing structures in the cavity 110, so that the angle code 20 can be accurately placed in a predetermined position during installation. At the same time, the existence of the convex ribs can also limit the movement of the angle code 20 in the vertical direction, thereby achieving the fixing effect on the angle code 20.

[0083] The corner code 20 is tightly clamped between the first convex rib 151 and the second convex rib 152 by means of interference fit. This tight connection can not only enhance the connection strength between the corner code 20 and the frame 1, but also reduce the risk of loosening or falling off due to vibration or external force. The fit between the convex rib and the corner code 20 can make the overall structure of the frame 1 more compact and stable. Under the action of external loads, the frame 1 can better resist deformation and damage, thereby protecting core components such as the internal photovoltaic panels from damage. In addition, the interference fit can also enhance the close contact between the corner code 20 and the frame 1, reducing problems such as water seepage or air leakage caused by excessive gaps.

[0084] It can be understood that the bottom wall and the top wall of the cavity 110 are respectively provided with the first rib 151 and the second rib 152, and the corner code 20 is clamped between the two ribs to achieve an interference fit with the cavity 110. This design can not only enhance the connection strength between the corner code 20 and the frame 1, but also improve the structural stability and durability of the photovoltaic module.

[0085] In some embodiments, Fig. 9 As shown, the bottom wall of the cavity 110 is provided with a first reinforcing rib 161 , and the top wall of the cavity 110 is provided with a second reinforcing rib 162 . The first reinforcing rib 161 partially extends into the water guide groove 250 , and the second reinforcing rib 162 contacts the angle code 20 .

[0086] The first reinforcing rib 161 is located on the bottom wall of the cavity 110, and its main function is to enhance the structural strength of the bottom of the frame 1, help resist the influence of external pressure on the frame 1, and maintain the integrity and stability of the frame 1. At the same time, the first reinforcing rib 161 partially extends into the water guide groove 250, and can also guide the water flow to pass through the water guide groove 250 more smoothly, reduce the resistance and eddy current of the water flow in the water guide groove 250, and improve the drainage efficiency.

[0087] The second reinforcing rib 162 is located on the top wall of the cavity 110 and is in direct contact with the corner code 20, which can enhance the connection strength between the corner code 20 and the frame 1, so that the corner code 20 can be more firmly fixed on the frame 1, which helps to resist deformation or damage of the frame 1 caused by looseness of the corner code 20.

[0088] The second reinforcing rib 162 can also improve the overall stability of the frame 1 by closely contacting the corner code 20. Under the action of external load, the frame 1 can better maintain the stability of its shape and size. The second reinforcing rib 162 helps to optimize the stress distribution inside the frame 1. When subjected to external pressure or vibration, the second reinforcing rib 162 can disperse and transfer stress and reduce the occurrence of local stress concentration, thereby extending the service life of the frame 1.

[0089] It can be understood that the bottom wall and the top wall of the cavity 110 are respectively provided with the first reinforcing rib 161 and the second reinforcing rib 162, which can further enhance the structural strength and stability of the frame 1. At the same time, the first reinforcing rib 161 partially extends into the water guide groove 250, and the second reinforcing rib 162 is in direct contact with the corner code 20, which can also optimize the drainage performance of the water guide groove 250 and improve the connection strength between the frame 1 and the corner code 20.

[0090] In some embodiments, Figure 2 and Figure 4 As shown, the docking of the drainage gap 120 has various structural forms, including but not limited to:

[0091] At least one end of the bottom wall of the cavity 110 of the side beam 10 is provided with a drainage gap 120, and multiple side beams 10 are connected end to end in sequence, then the two connected ends of adjacent side beams 10 are provided with at least one drainage gap 120, wherein the drainage gap 120 is triangular, and the drainage port 130 can be triangular or rectangular.

[0092] In example 1, the drainage notch 120 and an adjacent side beam 10 form a drainage opening 130 , and the drainage opening 130 is in a triangular shape.

[0093] like Figure 4 As shown, the end of the bottom wall of the cavity 110 of the side beam 10 is provided with an angle, and the angles of the adjacent ends of the bottom walls of the cavity 110 of two adjacent side beams 10 connected end to end are complementary to each other, so that the two adjacent side beams 10 form a vertical relationship during assembly, and the drainage notch 120 is a right triangle and corresponds to the end angle.

[0094] In this embodiment, the drain outlet 130 at the connection between two adjacent side beams 10 connected end to end is formed by a drainage gap 120, and the shape of the drain outlet 130 is the same as the drainage gap 120, which is a right triangle, that is, the connection end of one of the side beams 10 is provided with a drainage gap 120, and the connection end of the other side beam 10 may not be provided with a drainage gap 120, and the hypotenuse of the triangular drainage gap 120 and the end of the other side beam 10 form the drain outlet 130.

[0095] In the second example, the adjacent drainage notches 120 of the adjacent side beams 10 are butted together to form a drainage opening 130 , and the drainage opening 130 is rectangular.

[0096] like Figure 2 As shown, the end of the bottom wall of the cavity 110 of the side beam 10 is provided with an angle, and the angles of the adjacent ends of the bottom walls of the cavity 110 of two adjacent side beams 10 connected end to end are complementary to each other, so that the two adjacent side beams 10 form a vertical relationship during assembly, and the drainage notch 120 is a right triangle and corresponds to the end angle.

[0097] In this embodiment, the drain outlet 130 at the connection between two adjacent side beams 10 connected end to end is formed by two drainage gaps 120, and the shape of the drain outlet 130 is rectangular, that is, the connection ends of the two adjacent side beams 10 are each provided with a drainage gap 120, and the hypotenuse of the triangular drainage gap 120 is aligned with the hypotenuse of another drainage gap 120 to form a rectangular drain outlet 130.

[0098] It is understandable that the shape of the drain port 130 can be selected according to the specific installation environment and drainage requirements.

[0099] like Figure 4As shown, the triangular drainage notch 120 has a sharp bottom, which helps the water accumulated inside the frame 1 to flow out more smoothly along the edge of the triangle when it reaches a certain amount. The triangular shape can also keep the water flow at a high speed during the discharge process, thereby improving the drainage efficiency. When adjacent triangular drainage notches 120 are connected, they can form a larger drainage port 130 together, effectively guiding the rapid discharge of water.

[0100] The stability of the triangle can provide additional support and stability when the frame 1 is subjected to external pressure. The processing of the triangular drainage gap 120 is also relatively simple, and can be easily achieved through processes such as cutting or stamping, thereby reducing the production cost of the frame 1 and improving production efficiency. At the same time, the regular shape of the triangular gap can make the frame 1 easier to operate during installation and docking, reducing the difficulty and time of installation.

[0101] The drain outlet 130 can be designed to be triangular or rectangular, and the most suitable shape of the drain outlet 130 is selected mainly according to the specific installation environment and drainage requirements. For example, when a larger drainage area is required, a rectangular drain outlet 130 can be selected, and when space is limited or a higher drainage speed is required, a triangular drain outlet 130 can be selected.

[0102] It can be understood that the triangular drainage gap 120 can take into account both the drainage function and the structural stability of the frame 1, which helps to enhance the overall structural strength of the frame 1. In addition, the triangular drainage gap 120 is convenient for providing a support surface during stamping, which can alleviate the influence of machining marks near the drainage hole to a certain extent.

[0103] In some embodiments, Figure 5 As shown, the side beam 10 is provided with a clamping portion 140 for clamping the laminate, and the clamping portion 140 is located at a side of the main cavity 111 away from the drainage groove 112 .

[0104] The main function of the clamping portion 140 is to firmly clamp the laminate to reduce its movement or falling off inside the frame 1, so as to improve the stability and safety of the photovoltaic module. The clamping portion 140 can also protect the laminate. Through reasonable clamping force and method, the damage to the laminate when subjected to external impact or vibration can be reduced. At the same time, the clamping portion 140 can also have the function of improving the heat dissipation performance. By optimizing the structure and material selection of the clamping portion 140, the heat exchange between the laminate and the external environment can be promoted, thereby reducing the working temperature of the laminate and improving its working efficiency and life.

[0105] In addition, the main function of the drainage groove 112 is drainage. Disposing the clamping portion 140 on the side away from the drainage groove 112 can reduce the interference of the clamping portion 140 on the drainage efficiency of the drainage groove 112, and also help to optimize the overall structural layout of the frame 1, that is, the clamping portion 140 and the drainage groove 112 are respectively located on both sides of the main cavity 111, each assuming different functions, which can make the structure of the frame 1 more compact.

[0106] It can be understood that the clamping portion 140 is located on the side of the main cavity 111 away from the drainage groove 112, which can reduce the impact on the drainage groove 112 and can also stably clamp the laminate.

[0107] The embodiment of the present application further provides a photovoltaic assembly, comprising: a laminate and a frame 1 , wherein the laminate is mounted on the frame 1 .

[0108] The laminate is the core part of the photovoltaic module, which is usually composed of photovoltaic panels, transparent front covers, back panels and packaging materials. It is responsible for converting light energy into electrical energy. These materials are processed through a special lamination process to form an integral structure. It not only has excellent power generation performance, but also has good weather resistance and mechanical strength, and can work stably for a long time in various harsh environments.

[0109] The frame 1 is the supporting and protective structure of the photovoltaic module, and is usually made of metal materials or composite materials such as aluminum alloy and stainless steel. It can enhance the overall structural strength of the photovoltaic module and improve its compressive resistance. It can also integrate a drain port 130 to remove water accumulation inside the frame 1 and reduce damage to the laminate caused by water immersion.

[0110] The installation between the laminate and the frame 1 is usually carried out in a variety of ways, such as gluing, snap connection, etc., so that the laminate and the frame 1 are tightly fitted and firmly connected during the installation process to reduce loosening or falling off during subsequent use.

[0111] It can be understood that by firmly fixing the laminate in the frame 1, a complete and reliable photovoltaic module can be formed, which can meet the needs of various photovoltaic power generation systems.
