[0053] 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.

[0054] The present application aims to at least solve the technical problem that dust accumulation in the related art affects the light transmittance of the module. To this end, the present application proposes a photovoltaic module, a photovoltaic system, a laminated module and a frame, which can improve the light transmittance and power generation efficiency of the module.

[0055] Reference below Figure 1-Figure 5 A photovoltaic assembly 10 according to an embodiment of the present application is described.

[0056] like Figure 1 and Figure 2 As shown, the photovoltaic assembly 10 includes: a laminate 131 , a first frame 110 and a second frame 120 .

[0057] The first frame 110 is installed around the laminate 131, and the second frame 120 is provided with a clamping part 121, which clamps the laminate 131 and the first frame 110. The clamping part 121 is provided with a groove 122 on the side facing the laminate 131, and the structural adhesive filled between the clamping part 121 and the laminate 131 is embedded in the groove 122.

[0058] The laminate 131 is usually formed by connecting multiple solar cell units in series or in parallel and then laminating them with packaging materials. The packaging materials include EVA film and glass. The solar cell unit is the core of photoelectric conversion and can directly convert solar radiation energy into electrical energy. The laminate 131 is intended to protect the solar cell unit from the external environment and maintain a stable output of electrical energy.

[0059] The first frame 110 is installed around the laminate 131 and mainly plays the role of supporting and protecting the laminate 131. The first frame 110 can be made of a composite material, integrally formed and surrounding the laminate 131, which helps to enhance the overall structural strength of the photovoltaic module 10.

[0060] like Figure 3 As shown, the second frame 120 is provided with a clamping portion 121 for clamping the laminate 131 and the first frame 110, so that the second frame 120 is tightly fixed to the periphery of the laminate 131 and the first frame 110 to form a more stable structure. The material of the second frame 120 can be corrosion-resistant and high-strength metal such as aluminum alloy or stainless steel to improve the long-term stability of the photovoltaic module 10 in harsh outdoor environments.

[0061] The clamping portion 121 is recessed on one side of the laminate 131 to form a groove 122. The groove 122 can increase the contact area between the clamping portion 121 and the laminate 131, thereby improving the stability and reliability of the clamping. When pressure is applied to the clamping portion 121, the force can be more evenly distributed through the groove 122 to reduce damage caused by excessive local stress. The groove 122 can also increase the friction between the clamping portion 121 and the laminate 131 to reduce sliding or falling off under vibration or external force.

[0062] During the assembly process, the laminate 131 and the first frame 110 are first fixedly connected by the first structural adhesive 141 to form an integral component, and then the clamping portion 121 of the second frame 120 clamps the laminate 131 and the first frame 110, and the gap is filled with the second structural adhesive 142. This double-layer frame design can not only improve the protection level of the photovoltaic module 10, but also facilitate installation and maintenance. During the installation process, the second frame 120 can also serve as an additional support point to make the photovoltaic module 10 more firmly fixed on the bracket 30.

[0063] Composite materials have been widely used in the frame of photovoltaic modules 10, but in related technologies, traditional composite profile frame designs are usually integrated and seamlessly connected all around. In actual applications, dust is easily accumulated, which in turn affects the light transmittance and power generation efficiency of the module. In addition, the frame cross-section of the module does not take into account the force applied to the module, resulting in low material utilization, which easily leads to unnecessary excess material and waste of resources. At the same time, the pressing block 20 is a metal pressing block 20, which has the risk of conductive arcing and burning during daily use. Based on the above problems, this application adjusts the specific structure of the frame to solve the dust accumulation problem. At the same time, combined with the analysis of the force applied to the module frame, the material strength is fully utilized to save the frame material. The overall insulation performance is also improved by combining the composite frame module with the plastic insulating pressing block 20.

[0064] According to the photovoltaic module 10 provided in the embodiment of the present application, through the close cooperation between the first frame 110 and the second frame 120, the first frame 110 is integrally formed and seamlessly connected around the laminate 131. The second frame 120 clamps the laminate 131 and the first frame 110 and is arranged at two locations of the first frame 110 with greater force. The dustproof and self-cleaning capabilities of the photovoltaic module 10 can be enhanced, thereby improving the light transmittance and power generation efficiency of the photovoltaic module 10.

[0065] In some embodiments, Figure 3 and Figure 5 As shown, the first frame 110 includes a first section 111 and a second section 112 , the top of the first section 111 is flush with the upper surface of the laminate 131 , the second section 112 is parallel to the clamping portion 121 and the laminate 131 , and the first structural adhesive 141 is filled between the first frame 110 and the laminate 131 .

[0066] The first frame 110 includes a first section 111 and a second section 112, and the first section 111 and the second section 112 are perpendicular to each other to form an L-shaped structure. The top of the first section 111 is flush with the upper surface of the laminate 131, and the first frame 110 and the laminate 131 are fixedly connected by a first structural adhesive 141 to form a seamless overall structure, which can reduce dust accumulation. At the same time, the L-shaped first frame 110 can also enhance the edge strength of the photovoltaic module 10, making it more impact-resistant and resistant to external forces, which helps to reduce damage caused by accidental collisions or extrusion during installation, transportation or use. In addition, the flush design of the top of the first section 111 and the upper surface of the laminate 131 also helps to reduce heat accumulation caused by frame obstruction.

[0067] It can be understood that the top of the first section 111 of the first frame 110 is flush with the upper surface of the laminate 131, which can prevent dust accumulation in daily use.

[0068] In some embodiments, Figure 4 As shown, a groove 122 is provided on one side of the clamping portion 121 facing the laminate 131 , and a second structural adhesive 142 filled between the clamping portion 121 and the laminate 131 is embedded in the groove 122 .

[0069] The clamping portion 121 is recessed on one side of the laminate 131 to form a groove 122. The groove 122 can increase the contact area between the clamping portion 121 and the laminate 131, thereby improving the stability and reliability of the clamping. When pressure is applied to the clamping portion 121, the force can be more evenly distributed through the groove 122, reducing damage caused by excessive local stress. The groove 122 can also increase the friction between the clamping portion 121 and the laminate 131, reducing sliding or falling off under vibration or external force.

[0070] In the photovoltaic module 10, the clamping portion 121 of the second frame 120 is provided with a groove 122 for simultaneously clamping and fixing the first frame 110 and the laminate 131. The groove 122 can improve the stability of the laminate 131 in the second frame 120 and reduce the risk of displacement or damage of the laminate 131 due to external force.

[0071] During the assembly process, the laminate 131 and the first frame 110 are first fixedly connected by the first structural adhesive 141 to form an integral component, and then the clamping portion 121 of the second frame 120 clamps the laminate 131 and the first frame 110, and the gap is filled with the second structural adhesive 142. The second structural adhesive 142 filled between the clamping portion 121 and the laminate 131 is embedded in the groove 122.

[0072] It is understandable that the groove 122 is provided on the side of the clamping portion 121 facing the laminate 131, which can improve the stability and reliability of the clamping portion 121, thereby improving the performance and safety of the entire system.

[0073] In some embodiments, Figure 1 As shown, there are multiple second frames 120 , at least one second frame 120 is distributed on the first frame 110 along the length direction of the laminate 131 , and the length of the second frame 120 is less than that of the first frame 110 .

[0074] The first frame 110 surrounds the laminate 131, while the second frame 120 only provides additional support or fixation at key positions. For example, the second frame 120 is installed on the first frame 110 on both sides of the long side of the laminate 131. The long side of the laminate 131 is subjected to greater force, and the first frame 110 and the second frame 120 can be used to cooperate in force. The short side of the laminate 131 is subjected to less force, and only the first frame 110 needs to be used to bear the force, so as to save materials.

[0075] Multiple second frames 120 can be distributed at different positions on both sides of the long side of the laminate 131 to provide additional support and stability, which helps to reduce deformation or damage of the photovoltaic module 10 due to external factors. In addition, the length of the second frame 120 is 200mm~700mm, and the first frame 110 on one side of the long side of the laminate 131 can be evenly set with two second frames 120, and the other side of the long side of the laminate 131 corresponds to it.

[0076] The shorter second frame 120 can reduce the overall weight of the photovoltaic module 10 and simplify the installation process. During the production process, by using a shorter second frame 120, the material cost can be reduced without sacrificing the necessary strength and protection, and the load-bearing capacity of the bracket 30 can be improved to a certain extent.

[0077] It is understandable that the positions and quantities of the multiple second frames 120 can be flexibly adjusted to adapt to different installation conditions, which helps to simplify the installation process and improve installation efficiency. By reasonably distributing the multiple second frames 120, a more effective heat dissipation channel can also be formed to help reduce the temperature inside the photovoltaic module 10, improve the photovoltaic conversion efficiency, and extend the service life of the photovoltaic module 10.

[0078] The present application also provides a photovoltaic system 1, such as Figure 1 and Figure 4 As shown, the photovoltaic system 1 includes: a photovoltaic component 10 , a plurality of pressing blocks 20 and a bracket 30 .

[0079] The pressing block 20 is clamped with the second frame 120 ; the pressing block 20 is installed on the bracket 30 , and the bottom end of the second frame 120 abuts against the bracket 30 .

[0080] The photovoltaic assembly 10 is a core component of the photovoltaic system 1 , and mainly includes a laminate 131 , a plurality of first frames 110 and a second frame 120 , wherein the laminate 131 is responsible for photoelectric conversion, and the first frame 110 and the second frame 120 support and protect the laminate 131 .

[0081] The pressing block 20 is mainly used to fix the photovoltaic module 10 in the photovoltaic system 1 so that the photovoltaic module 10 is firmly mounted on the bracket 30. The pressing block 20 is connected to the second frame 120 by snap-fitting and connected to the bracket 30 by threading, which can provide additional support and stability.

[0082] The bracket 30 is a supporting structure of the photovoltaic system 1, used to carry the photovoltaic module 10 and fix it in a suitable position. The bracket 30 can be made of metal or non-metallic material and has sufficient strength and stability to withstand external forces such as wind load and snow load.

[0083] It is understandable that the photovoltaic assembly 10, the pressing block 20 and the bracket 30 work together to enhance the connection strength between the photovoltaic assembly 10 and the bracket 30, which helps to reduce the photovoltaic assembly 10 from falling off or being damaged under severe weather conditions.

[0084] In some embodiments, Figure 4 As shown, the pressing block 20 includes a pressing plate 210 and a connecting portion 220 , the pressing plate 210 contacts the second frame 120 , and the connecting portion 220 is connected to the bracket 30 .

[0085] The pressing plate 210 is the main working part of the pressing block 20, and is clamped with the second frame 120 to realize the connection between the photovoltaic module 10 and the pressing block 20. The pressing plate 210 has a specific clamping structure, and the part where the clamping structure contacts the second frame 120 is provided with a serrated structure, so as to closely cooperate with the second frame 120 to reduce slippage or looseness. At the same time, the pressing plate 210 and the second frame 120 have a large contact area, which can evenly apply pressure or provide a stable contact surface.

[0086] The connecting portion 220 is the portion connecting the pressing block 20 and the bracket 30, and is responsible for fixing the pressing block 20 to the bracket 30, thereby improving the stability and reliability of the pressing block 20. The connecting portion 220 may include various forms of connecting parts, such as screw holes, snaps or latches, etc., so as to match the corresponding structure on the bracket 30 and be firmly connected. At the same time, the end of the connecting portion 220 protrudes outward along the width direction of the laminate 131, which helps to increase the contact area with the bracket 30, disperse the pressure, and prevent the pressing block 20 from sliding on the bracket 30.

[0087] It can be understood that, through the close contact between the pressing plate 210 and the second frame 120 , and the firm connection between the connecting portion 220 and the bracket 30 , the second frame 120 can be fixed and supported.

[0088] In some embodiments, Figure 4 As shown, the connecting portion 220 includes a first extension section 221 and a second extension section 222 . The first extension section 221 is fixed to the bracket 30 via a threaded connector 40 . The end of the second section 222 abuts against the bracket 30 and protrudes outward along the width direction of the laminate 131 .

[0089] The first extension section 221 of the connecting portion 220 firmly fixes the pressing block 20 on the bracket 30 through a threaded connector 40. This connection method usually uses threaded connectors 40 such as bolts and nuts, and generates sufficient clamping force by tightening to ensure a tight connection between the pressing block 20 and the bracket 30. It has high strength and reliability and can withstand various forces and vibrations generated during the operation of the photovoltaic module 10.

[0090] The second section 222 of the connecting portion 220 can provide additional support and stability while ensuring close contact between the pressing block 20 and the bracket 30. The end of the second section 222 abuts the bracket 30, and the end protrudes outward along the width direction of the laminate 131, which can disperse the pressure and enhance the structural stability by increasing the contact area. At the same time, the part where the end of the second section 222 contacts the bracket 30 is also provided with a serrated structure so as to fit closely with the second frame 120 to reduce slippage or looseness.

[0091] It is understandable that the combined use of the threaded connector 40 and the protrusion design can ensure a firm connection and close contact between the pressing block 20 and the bracket 30, thereby improving the overall performance and reliability of the photovoltaic assembly 10.

[0092] In some embodiments, the pressing block 20 may be a plastic part to improve the insulation of the photovoltaic system 1 .

[0093] Plastic is a non-conductive material with good insulation properties. The use of plastic blocks 20 can effectively isolate current and reduce safety issues caused by current leakage or short circuits. In the photovoltaic system 1, good insulation properties can ensure that current flows in an orderly manner inside the component to avoid potential threats to the surrounding environment and equipment.

[0094] Plastic material generally has lower density and higher strength, so that the plastic pressing block 20 can reduce the weight of the entire photovoltaic system 1 while ensuring sufficient strength. The lightweight pressing block 20 helps to reduce installation difficulty and cost and improve the overall efficiency of the system.

[0095] High-quality plastic materials usually have excellent corrosion resistance and aging resistance, and can maintain stable performance for a long time in harsh environments. Plastic materials are also easy to process and can be made into blocks 20 of various shapes and sizes through injection molding, extrusion and other processes, thereby reducing production costs and improving production efficiency and flexibility.

[0096] It is understandable that the pressing block 20 is an important fixing device in the photovoltaic system 1, and the material selection has an important impact on the insulation and safety of the system. When the pressing block 20 is made of plastic, the insulation of the system can be improved to a certain extent.

[0097] In some embodiments, Figure 1 As shown, the bracket 30 extends along the width direction of the laminate 131 , and at least one pressing block 20 is fixed to the bracket 30 .

[0098] In the photovoltaic system 1, the bracket 30 is a key structure for supporting the photovoltaic module 10. When the bracket 30 extends along the width direction of the laminate 131, it can provide a stable support platform for the photovoltaic module 10 and enable the photovoltaic module 10 to be installed according to a predetermined layout and angle. The bracket 30 extends along the width direction of the laminate 131, that is, the length of the bracket 30 is greater than the width of the photovoltaic module 10. This design enables the bracket 30 to directly support the bottom or edge of the photovoltaic module 10, reducing the need for other auxiliary support structures.

[0099] At least one pressing block 20 is fixed on the bracket 30 to further fix the photovoltaic module 10. The pressing block 20 is connected to the second frame 120 of the photovoltaic module 10 through its specific clamping or fastening mechanism, and the photovoltaic module 10 is firmly fixed on the bracket 30. The number and position of the pressing blocks 20 are determined according to the size, weight and installation requirements of the photovoltaic module 10. For example, multiple pressing blocks 20 are used to disperse the weight and stress of the photovoltaic module 10 to improve the reliability and safety of the fixation.

[0100] It can be understood that, through the bracket 30 extending along the width direction of the laminate 131, the photovoltaic component 10 can obtain a more uniform distribution of supporting force, which helps to reduce the risk of deformation or damage caused by local stress concentration. At the same time, the fixation of at least one pressing block 20 can ensure the stable installation of the photovoltaic component 10, thereby improving the overall stability and safety of the photovoltaic system 1, and also helping to improve the power generation efficiency and extend the service life.

[0101] The present application also provides a laminate assembly 130, such as Figure 2 and Figure 5 As shown, the laminate assembly 130 includes: a laminate 131 and a first frame 110 , and the first frame 110 is installed around the laminate 131 .

[0102] The lamination assembly 130 is the core part of the photovoltaic system 1 , and is composed of a lamination 131 and a first frame 110 . The lamination 131 and the first frame 110 are formed into a whole by a first structural adhesive 141 , which can improve the mechanical strength and overall performance of the photovoltaic assembly 10 .

[0103] The laminate 131 is the core part of the laminate assembly 130, which is usually composed of multiple layers of materials through a lamination process. The cell is the power generation core of the photovoltaic assembly 10, which can convert solar energy into electrical energy. The packaging material is used to tightly bond the cell to other layers and provide protection. The back panel is located on the back of the laminate 131 to resist the damage of environmental factors. The glass cover is located at the front end of the laminate 131 to provide light transmittance and protect the cell.

[0104] The first frame 110 is a structural member installed around the laminate 131, which can provide additional support and protection for the laminate 131 and enhance the overall mechanical strength of the photovoltaic module 10. The first frame 110 is seamlessly connected to the laminate 131, which can reduce the intrusion of moisture and other harmful substances into the interior of the photovoltaic module 10.

[0105] It can be understood that the laminate assembly 130 can achieve efficient power generation and long-term stable operation of the photovoltaic assembly 10 through its unique structure and material selection.

[0106] The present application also provides a frame, such as Figure 2 and Figure 3 As shown, it includes: a first frame 110 and a plurality of second frames 120 , and the second frames 120 are provided with a clamping portion 121 for clamping the laminated assembly 130 .

[0107] In the photovoltaic module 10, the frame not only protects and supports the laminate 131, but also ensures the stable installation of the laminate assembly 130 through a specific design. The first frame 110 is made of a composite material, integrally formed and surrounds the laminate 131, which helps to enhance the overall structural strength of the photovoltaic module 10. The second frame 120 is usually made of metal material and has sufficient strength and weather resistance to withstand the influence of the external environment and the weight of the photovoltaic module 10.

[0108] The second frame 120 is provided with a clamping portion 121 for clamping the laminate assembly 130, so that the second frame 120 is tightly fixed to the periphery of the laminate assembly 130 to form a more stable structure. The clamping portion 121 is mainly designed with a specific shape and structure to tightly clamp the edge of the laminate assembly 130 to ensure the stable position of the laminate assembly 130 in the frame. This clamping method can not only ensure the structural integrity of the photovoltaic assembly 10, but also avoid performance degradation due to loosening or displacement. The clamping portion 121 usually also has a certain elasticity or buffering capacity, and can absorb external impact and vibration to a certain extent, protecting the laminate assembly 130 from damage.

[0109] It is understandable that the frame is an important component of the photovoltaic module 10, and the clamping portion 121 on the second frame 120 can ensure the stable position and protective effect of the laminate 131 in the frame through its unique clamping and fixing mechanism.
