Detailed Implementation

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0028] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be used interchangeably where appropriate for the embodiments of this application described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0029] The existing photovoltaic module frames are only connected at the ends by riveting, resulting in insufficient load-bearing capacity of the laminate in other parts of the frame (such as the middle of the frame). This makes the frame prone to deformation, which in turn causes the photovoltaic module to deform. When the photovoltaic module is placed on an outdoor support for a long time, it will dent. In the short term, this will affect the power generation efficiency of the photovoltaic power station, and in the long term, it may lead to the failure of the photovoltaic module.

[0030] As described in the background section, the frame of a photovoltaic module is prone to deformation in the prior art, which affects the performance of the photovoltaic module. In order to solve the above technical problems, the embodiments of this application provide a photovoltaic module frame and a photovoltaic module.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0032] This application provides a photovoltaic module frame. Figure 1 An exemplary top view of a photovoltaic module frame according to an embodiment of this application is shown, such as... Figure 2 An example shows along Figure 1 A schematic diagram of the cross-sectional structure of the photovoltaic module frame obtained by the dashed line AA'. Figure 3 An example shows along Figure 1 A schematic diagram of the cross-sectional structure of the photovoltaic module frame obtained by the dashed line BB', as shown below. Figures 1 to 3 As shown, the photovoltaic module frame 10 includes:

[0033] Two first frame frames 11, each first frame frame including a first top plate 12, a first partition plate 13, a first bottom plate 14 and a first connecting plate 15, the first top plate 12, the first partition plate 13 and the first bottom plate 14 are arranged at intervals along a first direction and their ends are all connected to the first connecting plate 15, the first connecting plates 15 of the two first frame frames 11 are arranged opposite to each other, the first connecting plate 15 has a first connection position, and the first direction is perpendicular to the direction in which the two first connecting plates 15 are opposite to each other;

[0034] Specifically, the first top plate 12, the first partition plate 13, and the first bottom plate 14 are arranged sequentially along the first direction, and the first top plate 12, the first partition plate 13, and the first bottom plate 14 can extend along the opposite directions of the two first connecting plates 15. The ends of the first top plate 12, the first partition plate 13, and the first bottom plate 14 located on the same side are connected to the first connecting plate 15. The extending direction of the first connecting plate 15 can be parallel to the first direction, or the angle between the extending direction of the first connecting plate 15 and the first direction can be an acute angle. The surface of the first top plate 12 away from the first partition plate 13 is the A-side of the first frame 11, the surface of the first bottom plate 14 away from the first partition plate 13 is the C-side of the first frame 11, and the surface of the first connecting plate 15 away from the ends of the first top plate 12, the first partition plate 13, and the first bottom plate 14 is the B-side of the first frame 11.

[0035] Two second frame borders 16, each second frame border 16 including a second top plate 17, a second partition plate 18, a second bottom plate 19, and a second connecting plate 20. The second top plate 17, the second partition plate 18, and the second bottom plate 19 are arranged at intervals along the first direction and their ends are all connected to the second connecting plate 20. The second connecting plates 20 of the two second frame borders 16 are arranged opposite to each other. The second frame borders 16 and the first frame border 11 are connected end to end to form a rectangular frame. The second connecting plate 20 has a second connection position.

[0036] Specifically, the second top plate 17, the second partition plate 18, and the second bottom plate 19 are arranged sequentially along the first direction, and the second top plate 17, the second partition plate 18, and the second bottom plate 19 can extend along the opposite directions of the two second connecting plates 20. The ends of the second top plate 17, the second partition plate 18, and the second bottom plate 19 located on the same side are connected to the second connecting plate 20. The extending direction of the second connecting plate 20 can be parallel to the first direction, or the angle between the extending direction of the second connecting plate 20 and the first direction can be an acute angle. The surface of the second top plate 17 away from the second partition plate 18 is the A-side of the second frame 16, the surface of the second bottom plate 19 away from the second partition plate 18 is the C-side of the second frame 16, and the surface of the second connecting plate 20 away from the ends of the second top plate 17, the second partition plate 18, and the second bottom plate 19 is the B-side of the second frame 16.

[0037] At least one connector 21 is located in the rectangular frame. The connector 21 has a first end and a second end. The first end of the connector 21 is connected to the first connection position, and the second end of the connector 21 is connected to the second connection position.

[0038] In the aforementioned embodiment, a first frame and a second frame are connected end-to-end to form a rectangular frame. A first connecting plate in the first frame has a first connecting position, and a second connecting plate in the second frame has a second connecting position. A connector located within the connecting frame has a first end and a second end. The first end of the connector is connected to the first connecting position, and the second end of the connector is connected to the second connecting position. This application, by setting a connector within the rectangular frame, with one end connected to the first connecting position on the first frame and the other end connected to the second connecting position on the second frame, achieves a fixed connection between the first and second frames. This improves the load-bearing capacity of the photovoltaic module frame, mitigates the problem of photovoltaic module frame deformation, and alleviates the problem of decreased power generation efficiency or even failure of the photovoltaic module caused by frame deformation, thus ensuring high performance and reliability of the photovoltaic module.

[0039] Specifically, such as Figure 1 As shown, the connector 21 provides a tensile force to the first frame 11 through the first connection position, pointing towards the other first frame 11, thereby preventing the B-face of the first frame 11 from bending outwards; the connector 21 provides a tensile force to the second frame 16 through the second connection position, pointing towards the other second frame 16, thereby preventing the B-face of the second frame 16 from bending outwards. The connector 21 provides support to the middle area of ​​adjacent first frame 11 and second frame 16, excluding the ends, alleviating the problem of frame deformation caused by the lack of support points in the middle of the frame.

[0040] This technical solution optimizes the structure of the photovoltaic module frame by introducing connectors, significantly enhancing its load-bearing capacity and stability. The connection between the connectors and the first and second frames effectively disperses external forces, reducing the risk of frame deformation under extreme environments such as wind pressure and snow loads. In the field of photovoltaic modules, the strength and stability of the frame are crucial to ensuring the long-term reliable operation of the module. This solution, through the combination of the frame and connectors, solves the structural stability problem of traditional photovoltaic module frames in harsh environments, including but not limited to improving wind pressure resistance, reducing stress concentration caused by thermal expansion and contraction, and enhancing the overall structural rigidity.

[0041] In practical applications, such as Figure 2 As shown, the first frame further includes a third connecting plate 22 extending along the first direction. The third connecting plate 22 is located between the first partition 13 and the first base plate 14, with one end connected to the first partition 13 and the other end connected to the first base plate 14. Figure 3As shown, the second frame also includes a fourth connecting plate 23, which extends along the first direction. The fourth connecting plate 23 is located between the second partition 18 and the second bottom plate 19, and one end of the fourth connecting plate 23 is connected to the second partition 18, while the other end of the fourth connecting plate 23 is connected to the second bottom plate 19.

[0042] In the embodiment, the third connecting plate further connects and fixes the first partition and the first base plate, serving to support the first partition and the first base plate and prevent the first partition or the first base plate from bending or deforming; the fourth connecting plate further connects and fixes the second partition and the second base plate, serving to support the second partition and the second base plate and prevent the second partition or the second base plate from bending or deforming.

[0043] In one alternative, such as Figure 1 As shown, the connector 21 includes a first connecting rod 24. One end of the first connecting rod 24 is the first end of the connector 21, that is, one end of the first connecting rod 24 is connected to the first connection position. The other end of the first connecting rod 24 is the second end of the connector 21, that is, the other end of the first connecting rod 24 is connected to the second connection position. The connection and fixation between the first frame and the second frame is achieved through a rod-shaped connector (i.e., the first connecting rod), further alleviating the deformation problem of the first or second frame.

[0044] Furthermore, the connector can be one of the first connecting rods.

[0045] In this embodiment, a first connecting rod is used as the connector. By fixing its two ends to the connection points of the first and second frames respectively, the connection strength between the first and second frames can be directly enhanced. Furthermore, the first connecting rod has a simple design, is easy to process and assemble, and can quickly reinforce the frame. During the installation and maintenance of photovoltaic modules, this direct reinforcement method can significantly improve work efficiency and reduce the risk of module damage caused by unstable frame connections. In addition, the choice of materials for the first connecting rod, such as metal or alloy, ensures that the connector has sufficient mechanical strength and corrosion resistance to meet the needs of long-term outdoor operation of photovoltaic modules.

[0046] Optionally, such as Figure 4As shown, the connector 21 includes: a third connecting rod 25, one end of which is the first end of the connector 21, i.e., one end of the third connecting rod 25 is connected to the first connection position; and a fourth connecting rod 26, one end of which is connected to the other end of the third connecting rod 25, and the other end of which is the second end of the connector, i.e., the other end of the fourth connecting rod 26 is connected to the second connection position. In this embodiment, the third connecting rod can provide additional support points for the first frame, and the fourth connecting rod can provide additional support points for the second frame, thereby further enhancing the stability of the photovoltaic module frame. This multi-point support connection method can effectively disperse stress and reduce deformation or damage to the frame caused by single-point force, further solving the reliability problem of traditional frame connection methods in complex environments.

[0047] Specifically, the connection between the third and fourth connecting rods can be achieved through welding, bolting, or other methods to ensure the reliability and durability of the connection.

[0048] In some alternative embodiments, such as Figure 5 As shown, the connector 21 includes: a first protrusion 27 located on the first base plate 14 and protruding towards the first partition 13; a second protrusion 28 located on the second base plate 19 and protruding towards the second partition; a fifth connecting rod 29, one end of which is the first end of the connector 21, i.e., one end of the fifth connecting rod 29 is connected to the first connection position, and the other end of the fifth connecting rod 29 is connected to the first protrusion 27; and a sixth connecting rod 30, one end of which is the second end of the connector 21, i.e., one end of the sixth connecting rod 30 is connected to the second connection position, and the other end of the sixth connecting rod 30 is connected to the second protrusion 28. In this embodiment, a protrusion is provided on the base plate of the frame, which, together with the fifth and sixth connecting rods, forms an innovative connection method. The design of the protrusion and connecting rod can provide additional support points for the middle of the frame, further alleviating the problem of frame depression and deformation caused by lack of support in the middle of the frame.

[0049] Specifically, the connection between the fifth and sixth connecting rods and the protrusion can be achieved by methods such as snap-fitting or riveting, which not only simplifies the assembly process but also ensures the tightness and durability of the connection.

[0050] According to some other embodiments of this application, such as Figure 2 and Figure 3As shown, the first connection position 31 is a first through hole penetrating the first connecting plate 15 along the direction towards the inside of the rectangular frame, and the second connection position 32 is a second through hole penetrating the second connecting plate 20 along the direction towards the inside of the rectangular frame. The first end of the connector passes through the first through hole, and the second end of the connector passes through the second through hole. The through hole design at the first and second connection positions allows the connector to directly pass through the connecting plate of the frame, realizing a direct connection between the frame and the connector. This connection method not only simplifies the assembly process but also ensures the tightness and strength of the connection.

[0051] Specifically, the via design in this application takes into account the thickness of the frame and the diameter of the connector, ensuring the reliability of the connection.

[0052] In other alternative embodiments, such as Figure 6 and Figure 7 As shown, the first connection position 31 is an opening facing the first groove inside the rectangular frame, and the second connection position 32 is an opening facing the second groove inside the rectangular frame. The first end of the connector has a first protrusion adapted to the first groove, and the second end of the connector has a second protrusion adapted to the second groove. The first protrusion is engaged in the first groove, and the second protrusion is engaged in the second groove. In this embodiment, the groove and protrusion are used for connection, allowing the connector to be connected to the frame in a snap-fit ​​manner. This connection method not only provides a mechanically stable connection but also supports the middle of the first frame and the middle of the second frame, further preventing deformation of the middle of the first and second frames.

[0053] Furthermore, this snap-fit ​​connection method facilitates disassembly and reassembly during the maintenance and upgrade of photovoltaic modules, improving the maintainability of the modules. Through the interaction of grooves and protrusions, the contradiction between ease of disassembly and connection stability in traditional frame connection methods is resolved, optimizing the maintenance process of photovoltaic modules, including but not limited to improving module detachability, enhancing connection tightness, and optimizing structural adaptability.

[0054] It should be noted that, Figure 1 , Figure 4 and Figure 5 Only one embodiment of the photovoltaic module frame including a connector is shown. In other embodiments, there may be multiple connectors. For example, one connector may be provided between each adjacent first and second frame, forming four connectors in the photovoltaic module frame; for example, in a rectangular frame, one connector may be provided between the two frames located at the lower left corner and one connector may be provided between the two frames located at the upper right corner.

[0055] In one specific embodiment, along the extending direction of the long side of the first connecting plate, the distance between the first connecting position and the end of the long side of the first connecting plate is a first distance. This first distance is greater than or equal to 0.15 times the length of the long side of the first connecting plate, and less than or equal to 0.75 times the length of the long side of the first connecting plate. The end of the long side of the first connecting plate is the end where the first frame connects to the second frame, and the extending direction of the long side is perpendicular to the first direction. This embodiment optimizes the position of the first connecting position and controls the relationship between the first distance and the length of the long side of the first connecting plate, ensuring the optimal connection position between the connector and the frame. This optimized design further supports the first frame and avoids the problem of excessive connector length leading to wasted connector materials.

[0056] In the structural design of photovoltaic modules, the position of the connectors has a significant impact on the overall strength and stability of the frame. By selecting appropriate positions, the layout problem of the connectors on the frame can be solved.

[0057] In another specific embodiment, along the extending direction of the long side of the second connecting plate, the distance between the second connecting position and the end of the long side of the second connecting plate is a second distance. This second distance is greater than or equal to 0.15 times the length of the long side of the second connecting plate, and less than or equal to 0.75 times the length of the long side of the second connecting plate. The end of the long side of the second connecting plate is the end where the second frame connects to the first frame, and the extending direction of the long side is perpendicular to the first direction. This embodiment optimizes the position of the second connecting position and, by controlling the relationship between the second distance and the length of the long side of the second connecting plate, ensures the optimal connection position between the connector and the frame. This optimized design not only further supports the second frame but also avoids the problem of excessively long connectors, which would lead to wasted connector materials.

[0058] For example, for the B-side of a photovoltaic module frame with dimensions of 2278*1134mm, mounting holes can be added at 400mm on each of the two long sides and at 300mm on each of the two short sides. A 4*500mm aluminum alloy beam is selected as a connector and fixed in the pre-drilled mounting holes to connect the long and short sides of the photovoltaic module frame. This improves the load-bearing capacity of the photovoltaic module frame, enhances the load capacity of the photovoltaic module, improves the deformation problem of the module placed in the photovoltaic power station for a long time, avoids the problem of reduced power generation efficiency caused by module deformation in the photovoltaic power station, and improves the reliability of the photovoltaic module.

[0059] Optionally, the connector material includes at least one of metals, alloys, and light-transmitting materials with a hardness greater than or equal to 65HA. Selecting metals, alloys, or light-transmitting materials as the connector material ensures that the connector possesses excellent mechanical properties and corrosion resistance. Metal materials, such as aluminum and steel, and alloy materials, such as aluminum alloys and stainless steel alloys, as well as light-transmitting materials, such as TPU (thermoplastic polyurethane elastomer), PMMA (polymethyl methacrylate), PC (polycarbonate), and TPX (poly4-methylpentene-1), can ensure the stability and durability of the connector during long-term outdoor operation of the photovoltaic module.

[0060] This application embodiment also provides a method such as Figure 8 The photovoltaic modules shown are as follows: Figure 8 As shown, the photovoltaic module includes:

[0061] Laminated component 33;

[0062] The photovoltaic module frame 10 described in any one of the above methods is used to encapsulate the laminate.

[0063] In the embodiments described, the photovoltaic module includes a laminate and any of the photovoltaic module frames. The photovoltaic module frame is fixed by setting a connector in a rectangular frame, with one end of the connector connected to a first connection position on the first frame and the other end connected to a second connection position on the second frame. This connection and fixation between the first and second frames is achieved through the connector, which can improve the load-bearing capacity of the photovoltaic module frame, improve the problem of photovoltaic module frame deformation, alleviate the problem of reduced power generation efficiency or even failure of the photovoltaic module caused by the deformation of the photovoltaic module frame, and ensure high performance and reliability of the photovoltaic module.

[0064] Specifically, such as Figure 8 As shown, the edge of the laminate 33 is located in the groove of the photovoltaic module frame formed by the top plate, connecting plate and partition plate.

[0065] The photovoltaic module frame structure and method disclosed in this application significantly enhance the load-bearing capacity and structural stability of the photovoltaic module frame by introducing connectors within the frame. Multiple implementation methods for the connectors not only provide flexible assembly options but also ensure the reliability and durability of the frame under various environmental conditions. Optimized design of the connection positions further improves the overall strength and wind pressure resistance of the frame, effectively preventing deformation and damage under extreme weather conditions. Furthermore, the selection of connector materials, such as metals or alloys, ensures the mechanical properties and corrosion resistance of the connectors, extending the service life of the photovoltaic module and reducing maintenance costs. The application of this solution not only improves the performance of photovoltaic modules but also promotes the development of the photovoltaic industry towards greater efficiency and environmental friendliness.

[0066] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0067] As can be seen from the above description, the embodiments described in this application achieve the following technical effects:

[0068] In the photovoltaic module frame of this application, a first frame and a second frame are connected end-to-end to form a rectangular frame. A first connecting plate in the first frame has a first connecting position, and a second connecting plate in the second frame has a second connecting position. A connector located within the connecting frame has a first end and a second end. The first end of the connector is connected to the first connecting position, and the second end of the connector is connected to the second connecting position. This application, by setting a connector within the rectangular frame, with one end connected to the first connecting position on the first frame and the other end connected to the second connecting position on the second frame, achieves a fixed connection between the first and second frames. This improves the load-bearing capacity of the photovoltaic module frame, mitigates the problem of photovoltaic module frame deformation, and alleviates the problem of decreased power generation efficiency or even failure of the photovoltaic module caused by frame deformation, thus ensuring high performance and reliability of the photovoltaic module.
