[0028] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the accompanying drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequential order.

[0029] The existing photovoltaic module frames are only connected by riveting at the ends of the frames, resulting in insufficient bearing capacity of the laminate at other positions of the frame except the ends (such as the middle of the frame), which is prone to frame deformation and photovoltaic module deformation. Photovoltaic modules will sag when placed on outdoor brackets for a long time, which will affect the power generation efficiency of the photovoltaic power station in the short term and may cause failure of the photovoltaic modules in the long term.

[0030] As introduced in the background technology, in the prior art, the frame of the photovoltaic module is easily deformed, which affects the performance of the photovoltaic module. To solve the above technical problems, the embodiments of the present application provide a photovoltaic module frame and a photovoltaic module.

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

[0032] The embodiment of the present application provides a photovoltaic module frame, Figure 1 The schematic diagram of the top view structure of a photovoltaic module frame provided in accordance with an embodiment of the present application is shown as an example. Figure 2 An example is shown along Figure 1 The schematic diagram of the cross-sectional structure of the photovoltaic module frame obtained by the AA' dashed line, Figure 3 An example is shown along Figure 1 The cross-sectional structure diagram of the photovoltaic module frame obtained by the BB' dashed line is as follows: Figures 1 to 3 As shown, the photovoltaic assembly frame 10 includes:

[0033] Two first frames 11, the first frames comprising 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 frames 11 are arranged opposite to each other, the first connecting plates 15 have a first connecting position, and the first direction is perpendicular to the opposite direction of the two first connecting plates 15;

[0034] Specifically, the first top plate 12, the first partition plate 13 and the first bottom plate 14 are arranged in sequence along the first direction, and the first top plate 12, the first partition plate 13 and the first bottom plate 14 may extend in directions opposite to 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 on the same side are connected to the first connecting plate 15. The extending direction of the first connecting plate 15 may be parallel to the first direction, and the extending direction of the first connecting plate 15 may also form an acute angle with the first direction. The surface of the first top plate 12 away from the first partition plate 13 is the A surface of the first frame 11, the surface of the first bottom plate 14 away from the first partition plate 13 is the C surface 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 surface of the first frame 11.

[0035] Two second frames 16, the second frames 16 comprising 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 connected to the second connecting plate 20, the second connecting plates 20 of the two second frames 16 are arranged opposite to each other, the second frames 16 and the first frames 11 are connected end to end in sequence to form a rectangular frame, and the second connecting plate 20 has a second connecting position;

[0036] Specifically, the second top plate 17, the second partition plate 18 and the second bottom plate 19 are arranged in sequence along the first direction, and the second top plate 17, the second partition plate 18 and the second bottom plate 19 can extend in the direction opposite to 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 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, and the extending direction of the second connecting plate 20 can also be an acute angle with the first direction. The surface of the second top plate 17 away from the second partition plate 18 is the A surface of the second frame 16, the surface of the second bottom plate 19 away from the second partition plate 18 is the C surface of the second frame 16, and the surface of the second connecting plate 20 away from the end of the second top plate 17, the second partition plate 18 and the second bottom plate 19 is the B surface of the second frame 16.

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

[0038] Through the embodiment, the first frame and the second frame are connected end to end to form a rectangular frame, the first connecting plate in the first frame has a first connecting position, the second connecting plate in the second frame has a second connecting position, the connector located in 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. The present application sets a connector in a rectangular frame, and one end of the connector is connected to the first connecting position on the first frame, and the other end of the connector is connected to the second connecting position on the second frame, so that the connection and fixation of the first frame and the second frame are achieved through the connector, which can improve the bearing capacity of the frame of the photovoltaic module, improve the problem of deformation of the frame of the photovoltaic module, alleviate the problem of reduced power generation efficiency of the photovoltaic module or even failure of the photovoltaic module caused by deformation of the frame of the photovoltaic module, and ensure the high performance and reliability of the photovoltaic module.

[0039] Specifically, Figure 1 As shown, the connecting member 21 provides a pulling force to the first frame 11 through the first connecting position, pointing to the direction of the other first frame 11, thereby preventing the B surface of the first frame 11 from bending outward; the connecting member 21 provides a pulling force to the second frame 16 through the second connecting position, thereby preventing the B surface of the second frame 16 from bending outward. The connecting member 21 provides a supporting force to the middle area of ​​the adjacent first frame 11 and the second frame 16 except the two ends, thereby alleviating the problem of the frame being easily deformed due to the lack of a supporting point in the middle of the frame.

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

[0041] In actual application, 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 plate 13 and the first bottom plate 14, and one end of the third connecting plate 22 is connected to the first partition plate 13, and the other end of the third connecting plate 22 is connected to the first bottom plate 14. Figure 3As shown, the second frame also includes: a fourth connecting plate 23 extending along the first direction, the fourth connecting plate 23 is located between the second partition plate 18 and the second bottom plate 19, and one end of the fourth connecting plate 23 is connected to the second partition plate 18, and the other end of the fourth connecting plate 23 is connected to the second bottom plate 19.

[0042] In the embodiment, the connection and fixation of the first partition plate and the first bottom plate are further achieved through the third connecting plate, which plays a role in supporting the first partition plate and the first bottom plate and preventing the first partition plate or the first bottom plate from bending and deformation; the connection and fixation of the second partition plate and the second bottom plate are further achieved through the fourth connecting plate, which plays a role in supporting the second partition plate and the second bottom plate and preventing the second partition plate or the second bottom plate from bending and deformation.

[0043] In one alternative, Figure 1 As shown, the connecting member 21 includes a first connecting rod 24, one end of the first connecting rod 24 is the first end of the connecting member 21, that is, one end of the first connecting rod 24 is connected to the first connecting position, and the other end of the first connecting rod 24 is the second end of the connecting member 21, that is, the other end of the first connecting rod 24 is connected to the second connecting position. The connection and fixation of the first frame and the second frame are achieved through a rod-shaped connecting member (that is, the first connecting rod), which further alleviates the deformation problem of the first frame or the second frame.

[0044] Furthermore, the connecting member may be one of the first connecting rods.

[0045] In the embodiment, a first connecting rod is used as a connecting member, and the connection strength between the first frame and the second frame can be directly enhanced by fixing the two ends of the first connecting rod to the connection positions of the first frame and the second frame respectively. In addition, the first connecting rod is simple in design, 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 connection. In addition, the material selection of the first connecting rod, such as metal or alloy, can ensure that the connecting member has sufficient mechanical strength and corrosion resistance to meet the needs of long-term outdoor operation of photovoltaic modules.

[0046] Alternatively, if Figure 4As shown, the connecting member 21 includes: a third connecting rod 25, one end of the third connecting rod 25 is the first end of the connecting member 21, that is, one end of the third connecting rod 25 is connected to the first connection position; a fourth connecting rod 26, one end of the fourth connecting rod 26 is connected to the other end of the third connecting rod 25, and the other end of the fourth connecting rod is the second end of the connecting member, that is, 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 an additional support point for the first frame, and the fourth connecting rod can provide an additional support point 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 of the frame caused by single-point force, further solving the reliability problem of the traditional frame connection method in complex environments.

[0047] Specifically, the connection between the third connecting rod and the fourth connecting rod can be achieved by welding, bolt fixing, etc., to ensure the reliability and durability of the connection.

[0048] In some other optional embodiments, Figure 5 As shown, the connecting member 21 includes: a first protrusion 27, which is located on the first bottom plate 14 and protrudes toward the first partition 13; a second protrusion 28, which is located on the second bottom plate 19 and protrudes toward the second partition; a fifth connecting rod 29, one end of which is the first end of the connecting member 21, that is, one end of the fifth connecting rod 29 is connected to the first connecting position, and the other end of the fifth connecting rod 29 is connected to the first protrusion 27; a sixth connecting rod 30, one end of which is the second end of the connecting member 21, that is, one end of the sixth connecting rod 30 is connected to the second connecting 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 bottom plate of the frame, and cooperates with the fifth connecting rod and the sixth connecting rod to form an innovative connection method. The design of the protrusion and the connecting rod can provide an additional support point for the middle of the frame, further alleviating the problem of frame concavity and deformation caused by lack of support force in the middle of the frame.

[0049] Specifically, the fifth connecting rod and the sixth connecting rod can be connected to the protruding portion by means of snap-fitting, riveting, etc., which not only simplifies the assembly process but also ensures the tightness and durability of the connection.

[0050] According to some further embodiments of the present application, Figure 2 and Figure 3As shown, the first connection position 31 is a first through hole that passes through the first connection plate 15 in the direction toward the inside of the rectangular frame, the second connection position 32 is a second through hole that passes through the second connection plate 20 in the direction toward 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 first connection position and the second connection position adopt a through hole design, so that the connector can directly pass through the connection 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 design of the via in the present application takes into account the thickness of the frame and the diameter of the connector, thereby ensuring the reliability of the connection.

[0052] In some other optional embodiments, Figure 6 and Figure 7 As shown, the first connection position 31 is a first groove opening toward the inside of the rectangular frame, the second connection position 32 is a second groove opening toward the inside of the rectangular frame, the first end of the connector has a first protrusion matching the first groove, the second end of the connector has a second protrusion matching the second groove, the first protrusion snaps into the first groove, and the second protrusion snaps into the second groove. In this embodiment, the groove and the protrusion are matched to each other, so that the connector can be connected to the frame in the form of a buckle. This connection method not only provides a mechanically stable connection, but also plays a role in supporting the middle of the first frame and the middle of the second frame, further avoiding the deformation problem of the middle of the first frame and the second frame.

[0053] In addition, during the maintenance and upgrade of photovoltaic modules, this snap-on connection method facilitates disassembly and reassembly, improving the maintainability of the modules. Through the interaction between the grooves and protrusions, the contradiction between the traditional frame connection method in terms of disassembly and assembly convenience and connection stability is solved, and the maintenance process of photovoltaic modules is optimized, including but not limited to improving the disassembly of the modules, enhancing the tightness of the connection, and optimizing the adaptability of the structure.

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

[0055] In a specific embodiment, along the extension direction of the long side of the first connecting plate, the distance between the first connecting position and the long side end of the first connecting plate is a first distance, the 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 long side end of the first connecting plate is the end where the first frame and the second frame are connected, and the extension direction of the long side is perpendicular to the first direction. This embodiment optimizes the position of the first connecting position and controls the size relationship range between the first distance and the long side length of the first connecting plate to ensure the optimal connection position of the connector and the frame. This optimized design can not only further support the first frame, but also avoid the problem of excessive length of the connector, which causes waste of connector consumables.

[0056] In the structural design of photovoltaic modules, the position of the connectors has an important impact on the overall strength and stability of the frame. By selecting a reasonable position, the layout problem of the connectors on the frame is solved.

[0057] In another specific embodiment, along the extension direction of the long side of the second connecting plate, the distance between the second connecting position and the long side end of the second connecting plate is a second distance, the 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 long side end of the second connecting plate is the end where the second frame is connected to the first frame, and the extension direction of the long side is perpendicular to the first direction. This embodiment optimizes the position of the second connecting position and controls the size relationship range between the second distance and the long side length of the second connecting plate to ensure the optimal connection position of the connector and the frame. This optimized design can not only further support the second frame, but also avoid the problem of excessive length of the connector, which causes waste of connector consumables.

[0058] For example, for the B side of the photovoltaic module frame with a length and width of 2278*1134mm, mounting holes can be added at 400mm in the two long sides and 300mm in the two short sides, and a 4*500mm aluminum alloy beam is selected as a connecting part, and the aluminum alloy beam is fixed in the drilled mounting holes to achieve the connection between the long frame and the short frame of the photovoltaic module frame, thereby improving the bearing capacity of the photovoltaic module frame, improving the load capacity of the photovoltaic module, improving the deformation problem of components placed in photovoltaic power stations for a long time, avoiding the problem of reduced power generation efficiency of photovoltaic power stations due to component deformation, and improving the reliability of photovoltaic modules.

[0059] Optionally, the material of the connector includes at least one of a metal, an alloy material, and a light-transmitting material having a hardness greater than or equal to 65HA. Metal, alloy, or light-transmitting material is selected as the material of the connector so that the connector has excellent mechanical properties and corrosion resistance. Metal materials such as aluminum and steel, and alloy materials such as aluminum alloy and stainless steel alloy, and light-transmitting materials such as TPU (thermoplastic polyurethane elastomer), PMMA (polymethyl methacrylate), PC (polycarbonate), and TPX (poly-4-methylpentene-1), etc., can ensure the stability and durability of the connector in the long-term outdoor operation of the photovoltaic module.

[0060] The present application also provides a method Figure 8 The photovoltaic modules shown, such as Figure 8 As shown, the photovoltaic assembly includes:

[0061] Laminate 33;

[0062] Any one of the photovoltaic assembly frames 10 is used to encapsulate the laminate.

[0063] In the described embodiment, the photovoltaic module includes a laminate and any one of the described photovoltaic module frames. The photovoltaic module frame is formed by arranging a connector in a rectangular frame, and one end of the connector is connected to a first connection position on the first frame, and the other end of the connector is connected to a second connection position on the second frame, so that the first frame and the second frame are connected and fixed by the connector, which can enhance the bearing capacity of the photovoltaic module frame, improve the problem of deformation of the photovoltaic module frame, alleviate the problem of reduced power generation efficiency of the photovoltaic module or even failure of the photovoltaic module due to deformation of the photovoltaic module frame, and ensure high performance and reliability of the photovoltaic module.

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

[0065] The photovoltaic module frame structure and method of the present application significantly enhance the bearing capacity and structural stability of the photovoltaic module frame by introducing connectors into the frame. The various implementation methods of the connectors not only provide flexible assembly options, but also ensure the reliability and durability of the frame under different environmental conditions. The optimized design of the connection position further improves the overall strength and wind pressure resistance of the frame, and effectively prevents the deformation and damage of the frame under extreme climates. In addition, the selection of connector materials, such as metals or alloys, ensures the mechanical properties and corrosion resistance of the connectors, extends the service life of the photovoltaic module, and reduces maintenance costs. The application of this solution not only improves the performance of photovoltaic modules, but also promotes the development of the photovoltaic industry in a more efficient and environmentally friendly direction.

[0066] It should also be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, commodity or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, commodity or device.
