Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic components, in particular to a photovoltaic component frame and a photovoltaic component. Background Art

[0002] Photovoltaic modules, also known as solar panels, are one of the core components of photovoltaic power generation systems. They are generally composed of a laminate and a frame, with the frame located at the edge of the laminate.

[0003] Most of the frames in the related art have an A surface, such as Figure 12 As shown, the A side of this frame is approximately 3 mm higher than the laminate. However, this type of frame presents numerous challenges when installed at a shallow angle. For example, dust on the module surface is difficult to slide off and accumulates, obstructing the module and reducing power generation. It can also cause hot spots and even pose safety risks. Furthermore, regular cleaning of the module surface is costly.

[0004] In the prior art, frames without an A-side are typically designed by simply removing the A-side from existing frames. However, this approach alters the frame's overall structure, significantly reducing its load-bearing capacity. In actual use, the frame must withstand the weight of the component itself as well as various external forces such as wind. If this load-bearing capacity is insufficient, the frame is prone to deformation or even damage, which can seriously affect the stability and safety of the entire component.

[0005] Based on this, the present invention develops a new type of photovoltaic module frame and photovoltaic module to solve the above problems. Utility Model Content

[0006] One purpose of the present utility model is to provide a photovoltaic module frame, the design of which achieves the effects of improving power generation efficiency, reducing safety hazards, reducing maintenance costs, and improving bearing capacity and structural stability by eliminating the A-side design and widening the supporting frame.

[0007] The utility model adopts the following technical solution: a photovoltaic module frame, the photovoltaic module frame includes a frame body portion, the frame body portion has a first support frame portion, the first end of the first support frame extends upward to form a side wall portion;

[0008] The second end of the first support frame extends away from the first end to form a second support frame. The second support frame bends downward away from one end of the first support frame and is combined with the second support frame to form a closed first cavity structure. The first cavity structure includes a load-bearing frame, which is used to support the second support frame.

[0009] Furthermore, a baffle portion is provided at one end of the side wall away from the first support frame; the distance between the top surface of the baffle portion and the first support frame is less than or equal to the thickness of the laminate; and the first support frame, the side wall portion and the baffle portion together form a first glue overflow groove.

[0010] Furthermore, the middle portion of the contact surface between the baffle portion and the laminate is recessed inwardly to form a second glue overflow groove;

[0011] And / or, the side wall portion close to the first supporting frame is tooth-shaped.

[0012] Furthermore, the first supporting frame and the second supporting frame are an integrated structure, constituting a supporting frame.

[0013] Furthermore, the middle portion of the support frame is recessed inward to form a third glue overflow groove;

[0014] Or the middle portion of the supporting frame arches upward to form a convex structure with a plane, and the convex structure, the supporting frame and the side wall portion form a fourth glue overflow groove.

[0015] Furthermore, the third glue overflow groove is trapezoidal, including a first trapezoidal angle and a second trapezoidal angle, and at least one of the first trapezoidal angle and the second trapezoidal angle is an acute angle.

[0016] Furthermore, the top of the supporting frame abuts against the third glue overflow groove or the protruding structure.

[0017] Furthermore, the first cavity structure also includes a beveled frame, one end of the beveled frame is connected to the end of the second supporting frame away from the first supporting frame, the other end of the beveled frame is connected to the bottom of the carrying frame, and the top of the carrying frame is connected to the second supporting frame; wherein, the beveled frame is located on the outside of the carrying frame, and the top of the beveled frame is inclined toward the side away from the carrying frame.

[0018] Furthermore, the frame body is a second cavity structure.

[0019] Compared with the related art, the beneficial effects of the present invention are:

[0020] In the photovoltaic module frame of the present invention, the first supporting frame provides support for the laminate, which is equivalent to eliminating the A-side design in the prior art frame. Therefore, when the module is installed at a relatively small tilt angle, dust will not accumulate on the module surface due to the A-side being higher than the laminate. This can effectively prevent the module from being blocked, ensure that the module can fully receive light, thereby increasing power generation, avoiding the problem of hot spots caused by dust accumulation, reducing safety hazards, and effectively solving the problem of dust accumulation on the module surface. At the same time, since there is no A-side that is prone to dust accumulation, the need for regular cleaning of the module surface is greatly reduced, thereby saving cleaning costs.

[0021] The second end of the first support frame extends to form a second support frame. This design expands the boundaries of the original first support frame, allowing the entire frame structure to extend in the lateral dimension, thereby achieving the effect of widening the support frame. This widening design provides a larger contact area for the laminate and the adhesive. The increase in contact area means that the adhesive can more fully exert its bonding effect, making the connection between the laminate and the frame more secure and reliable. At the same time, due to the increase in contact area between the laminate and the adhesive, when the component is subjected to external forces, the stress can be more effectively dispersed, significantly improving the component's load-bearing capacity, enabling it to withstand greater external loads such as wind and snow loads, and greatly enhancing the stability and durability of the photovoltaic module under various environmental conditions. In addition, the widened support frame, combined with the design of the first cavity structure, supports the second support frame with the load-bearing frame, providing a more stable support structure for the photovoltaic module, enhancing the overall strength and rigidity of the frame, reducing the risk of deformation and distortion of the frame during use, helping to maintain the shape and performance of the photovoltaic module and improving its long-term reliability. Ultimately, the problem of insufficient load-bearing capacity of the A-sideless module and the explosive panels on the four sides of the laminate were successfully solved, achieving a good frame load-bearing effect.

[0022] The second object of the present invention is to provide a photovoltaic module, a photovoltaic module, which includes a laminate; and a frame, the frame is installed on the edge of the laminate, wherein the frame of at least one side of the laminate is the above-mentioned photovoltaic module frame.

DETAILED DESCRIPTION

[0039] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] The following is combined with Figure 1 To the attached Figure 14 And specific embodiments describe the present invention in detail:

[0041] like Figures 1 to 11 As shown, the present invention provides a photovoltaic module frame for mounting a laminate 4. The photovoltaic module frame includes a frame body 1 having a first support frame 10. The first support frame 10 is used to support the ends of the laminate 4 and provide support for the laminate 4. The first support frame 10 is arranged horizontally and includes a first end 101 on the left and a second end 102 on the right. The first end 101 of the first support frame 10 extends upward to form a sidewall portion 11, which is equivalent to eliminating the A-side design of the frame in the related art.

[0042] The second end 102 of the first support frame 10 extends away from the first end to form a second support frame 5. The second support frame 5 is bent downward away from one end of the first support frame 10 and is surrounded by the second support frame 5 to form a closed first cavity structure 6. The first cavity structure 6 includes a load-bearing frame 60, which is used to support the second support frame 5 and provide supporting force for the second support frame 5.

[0043] In the photovoltaic module frame of the present invention, the first support frame 10 provides support for the laminate 4, which is equivalent to eliminating the A-side design in the frame of the related art. Therefore, when the module is installed at a small tilt angle, dust will not accumulate on the module surface due to the A-side being higher than the laminate. This can effectively prevent the module from being blocked, ensure that the module can fully receive light, thereby increasing power generation, avoiding the hot spot problem caused by dust accumulation, reducing safety hazards, and effectively solving the problem of dust accumulation on the module surface. At the same time, since there is no A-side that is prone to dust accumulation, the need for regular cleaning of the module surface is greatly reduced, thereby saving cleaning costs.

[0044] The second end 102 of the first support frame 10 extends to form a second support frame 5. This design expands the boundaries of the original first support frame 10, allowing the entire frame structure to extend in the lateral dimension, thereby achieving the effect of widening the support frame. This widening design provides a larger contact area for the laminate 4 and the adhesive. The increase in contact area means that the adhesive can more fully exert its bonding effect, thereby making the connection between the laminate 4 and the frame more secure and reliable. At the same time, due to the increase in contact area between the laminate 4 and the adhesive, when the assembly is subjected to external forces, stress can be more effectively dispersed, significantly improving the load-bearing capacity of the assembly, enabling it to withstand greater external loads such as wind and snow loads, and greatly enhancing the stability and durability of the photovoltaic assembly under various environmental conditions. In addition, the widened support frame, combined with the design of the first cavity structure 6, supports the second support frame 5 by the load-bearing frame 60, providing a more stable support structure for the photovoltaic assembly, enhancing the overall strength and rigidity of the frame, reducing the risk of deformation and distortion of the frame during use, helping to maintain the shape and performance of the photovoltaic assembly and improving its long-term reliability. Ultimately, the problems of insufficient load-bearing capacity of the A-side-less component and the explosive panels on the four sides of the laminate were successfully solved, achieving a good frame load-bearing effect.

[0045] Furthermore, in some embodiments, a baffle portion 3 is provided at one end of the side wall portion 2 away from the first support frame 10; the distance between the top surface of the baffle portion 3 and the first support frame 1 is less than or equal to the thickness of the laminate 4, that is, when the laminate 4 is installed, the baffle portion 3 is only connected to the side of the laminate 4, which is equivalent to canceling the A-side design in the prior art frame, and the distance between the top surface of the baffle portion 3 and the first support frame 1 is less than or equal to the thickness of the laminate 4, so that dust will not accumulate on the surface of the component due to the A-side being higher than the laminate. This can effectively prevent the component from being blocked, ensure that the component can fully receive light, thereby increasing power generation, avoiding hot spots caused by dust accumulation, reducing safety hazards, and effectively solving the problem of dust accumulation on the surface of the component. At the same time, the first support frame 10, the side wall portion 2 and the baffle portion 3 form a first glue overflow groove 7. The first glue overflow groove 7 is a U-shaped groove with an opening toward the side of the laminate 4, which can store more silicone, thereby effectively reducing the risk of glue overflow. In this embodiment, the first glue overflow groove 7 is formed by folding a metal plate, specifically, the top of the side wall portion 2 is bent to form the baffle portion 3; preferably, the metal plate is a galvanized steel plate. The U-shaped design of the first glue overflow groove 7 provides sufficient storage space for silicone, which can accommodate more adhesives, avoid adhesive overflow during the installation and use of the photovoltaic module, and ensure the neatness and stability of the installation. And by providing additional glue storage space, the risk of glue overflow causing pollution and damage to the laminate 4 and surrounding components is effectively reduced, thereby improving the reliability and service life of the photovoltaic module. At the same time, the provision of the first glue overflow groove 7 helps to increase the contact area between the laminate 4 and the adhesive, thereby enhancing the bonding effect between the two, making the connection between the laminate 4 and the frame more firm and reliable, and improving the stability of the photovoltaic module under various environmental conditions.

[0046] In some more specific embodiments, the middle portion of the abutment surface between the baffle portion 3 and the laminate 4 is recessed inward to form a second glue overflow groove 30. The second glue overflow groove 30 is used to store silicone and enhance the bonding strength between the baffle portion 3 and the laminate 4. Specifically, the shape and number of the second glue overflow groove 30 are not specifically limited in this utility model and can be U-shaped, V-shaped, or W-shaped. Any selection by those skilled in the art based on actual conditions is within the scope of protection of this utility model.

[0047] In some more specific embodiments, Figure 10As shown, the side wall portion 2 is serrated on the side close to the first supporting frame 10, so as to achieve the effect of increasing the contact area of ​​the first glue overflow groove 7. The serrated side wall portion 2 significantly increases the contact area between the first glue overflow groove 7 and the glue. More contact points allow the glue to better adhere to the glue overflow groove, improving the adhesion between the glue and the frame, thereby enhancing the stability of the connection between the laminate 4 and the frame. At the same time, the serrated structure helps to guide the glue to be more evenly distributed in the glue overflow groove, which can avoid local accumulation or insufficiency of the glue, ensure the uniform distribution of the glue in the bonding area, and improve the bonding quality. Specifically, the side wall portion 2 is made of a metal plate, and the serrated structure is formed by bending the plate; preferably, the metal plate is a galvanized steel plate. It should be noted that the number of the first glue overflow grooves 7 can be one or more, and is not specifically limited in the present utility model.

[0048] Furthermore, in some embodiments, Figures 1 to 11 As described, the baffle portion 3 and the side wall portion 2 are integrally formed, and the baffle portion 3 is horizontally arranged on the top of the side wall portion 2, and its width is about 1.2mm to 1.8mm. In a preferred embodiment, the integrally formed baffle portion 3 and the side wall portion 2 are in an inverted L-shaped structure, and the horizontal width of the inverted L-shaped structure is 1.2mm to 1.8mm. Those skilled in the art will know that the width of the A-side structure on a conventional frame is generally 11.0mm to 11.5mm. It can be seen that the baffle portion 3 of the present application adopts a width design of 1.2mm to 1.8mm, which can greatly reduce the material cost of the frame. At the same time, since the baffle portion 3 no longer covers the upper surface of the laminate 4, the power generation loss of the photovoltaic module can be reduced and the power generation efficiency can be improved.

[0049] It should be noted that the baffle portion (i.e., surface A) of a conventional photovoltaic module frame is typically higher than the laminate and contacts the upper surface of the laminate, shielding the edge of the laminate. This design can cause a large amount of dust to adhere to the edge of the laminate during long-term outdoor use of the photovoltaic module and cannot be eliminated on its own, leading to the occurrence of hot spots. However, the top surface of the baffle portion of the present application does not exceed the upper surface of the laminate, eliminating the space for dust to accumulate, preventing dust from accumulating stably on the photovoltaic module and allowing it to be eliminated on its own by strong winds or rain.

[0050] Furthermore, in some specific embodiments, the first supporting frame 10 and the second supporting frame 5 are an integrated structure, forming a supporting frame. Figure 1 、 2 As shown in , 4, 7-11, the middle part of the support frame is recessed inward to form a third glue overflow groove 8, which can effectively prevent the adhesive from overflowing to the back of the laminate 4. This can keep the laminate clean and avoid the performance and appearance of the photovoltaic module being affected by adhesive contamination. In a more preferred embodiment, as Figure 4As shown, the bottom surface of the third overflow glue groove 8 is serrated to increase the contact area of ​​the third overflow glue groove 8. The serrated bottom surface of the third overflow glue groove 8 increases the contact area with the adhesive. The larger contact area helps to improve the adhesion of the adhesive and enhance the connection strength between the laminate 4 and the frame.

[0051] At the same time, if Figure 1 As shown, the third glue overflow groove 8 is trapezoidal, including a first trapezoidal angle 80 and a second trapezoidal angle 81, and at least one of the first trapezoidal angle 80 and the second trapezoidal angle 81 is an acute angle. The third glue overflow groove 8 is trapezoidal, and at least one trapezoidal angle is an acute angle. Extending inward increases the capacity of the glue overflow groove, so that it can accommodate more adhesive and reduce the risk of glue overflow, especially during the gluing process, and can provide enough space for the flow of glue. At the same time, the design of the acute angle extending inward also has a buffering effect. When the photovoltaic module is subjected to external force impact or temperature changes, the adhesive has a certain buffer space in the glue overflow groove, which can reduce the stress on the laminate 4 and the frame, and improve the impact resistance and durability of the photovoltaic module. More preferably, the first trapezoidal angle 80 and the second trapezoidal angle 81 in the third glue overflow groove 8 are both acute angles.

[0052] Furthermore, in some specific embodiments, the first supporting frame 10 and the second supporting frame 5 are an integrated structure, forming a supporting frame. Figure 5 、 6 As shown, the middle portion of the support frame can be arched upward to form a flat raised structure 9. The raised structure 9, the support frame, and the sidewall portion 2 define a fourth overflow adhesive groove 90 for storing adhesive. Similarly, the bottom surface of the fourth overflow adhesive groove 90 can also be designed in a toothed shape to increase the contact area with the adhesive. This larger contact area helps improve the adhesion of the adhesive and enhances the connection strength between the laminate 4 and the frame.

[0053] It should be noted that the present invention does not limit the number and formation of the third and fourth glue overflow grooves 8 and 90. For example, the third and fourth glue overflow grooves 8 and 90 can be formed by folding a metal plate, and can be folded upward, folded downward, folded inward, folded outward, etc. The specific design and selection can be made by those skilled in the art based on actual conditions. Similarly, the bottom surfaces of the third and fourth glue overflow grooves 8 and 90 are tooth-shaped and can also be formed by bending a metal plate.

[0054] Furthermore, in some specific embodiments, Figure 1-2As shown in Figures 4-11, the top of the support frame 60 abuts against the third glue overflow groove 8 or the raised structure 9, which is equivalent to adding a support point in the middle of the support frame. This effectively prevents the support frame from bending or deforming when subjected to force. The top of the support frame 60 abuts against the third glue overflow groove 8 or the raised structure 9, providing additional support for the middle of the support frame, making the entire structure more stable and reliable when subjected to external forces.

[0055] Furthermore, in some specific embodiments, the first cavity structure 6 also includes a beveled frame 61, one end of the beveled frame 61 is connected to the end of the second supporting frame 5 away from the first supporting frame 10, the other end of the beveled frame 61 is connected to the bottom of the load-bearing frame 60, the top of the load-bearing frame 60 is connected to the second supporting frame 5, the beveled frame 61 is located outside the load-bearing frame 60, and the top of the beveled frame 61 is inclined toward the side away from the load-bearing frame 60, and finally the beveled frame 61, the load-bearing frame 60 and the second support frame 5 together form a closed triangular cavity structure. The triangular cavity structure formed by the beveled frame 61, the load-bearing frame 60 and the second support frame 5 has a high degree of stability and can provide strong support for the photovoltaic module frame. This stable structure can better withstand external loads such as wind, snow pressure, etc., and improve the load-bearing capacity of the module under various environmental conditions. At the same time, the triangular cavity structure is more compact and efficient in design. Compared with traditional rectangular or other shaped cavity structures, the triangular structure can reduce the amount of material used while meeting the load requirements. By rationally designing the sizes and angles of the oblique frame 61 , the load-bearing frame 60 and the second supporting frame 5 , the distribution of materials can be optimized to the greatest extent and the cost can be reduced.

[0056] Furthermore, reducing material usage means reducing the weight of the PV panel frames, which is beneficial for the installation and transportation of PV systems, reducing installation costs and transportation energy consumption. Furthermore, lightweight frames also help reduce the requirements for supporting structures, improving the economic efficiency and sustainability of the entire PV system.

[0057] It should be noted that the supporting frame 60 can be set vertically or tilted, which is not specifically limited in the present invention and can be designed and selected by those skilled in the art based on actual conditions.

[0058] In some more specific embodiments, the first cavity structure 6 may further include a bottom frame 62 and a buffer frame 63. The buffer frame 63 is arranged between the second support frame 5 and the oblique frame 61, and is perpendicular to the second support frame 5; the bottom frame 62 is arranged between the oblique frame 61 and the load-bearing frame 60, and is parallel to the second support frame 5. By providing the buffer frame 63 and the bottom frame 62, stress can be effectively dispersed to avoid stress concentration in specific parts. Correspondingly, the uniform distribution of stress improves the overall stability of the entire first cavity structure 6 and the photovoltaic module frame, enabling it to better withstand external loads and internal stresses, and reduce the risk of deformation and damage caused by stress concentration. It should be noted that the first cavity structure 6 is preferably formed by folding a metal sheet. In the process of folding the metal sheet to form the first cavity structure 6, the design of adding the bottom frame 62 and the buffer frame 63 can provide additional support and constraints, reduce stress concentration and deformation of the metal sheet at the folding point, help prevent cracks in the metal sheet during the folding process, and improve the quality and reliability of the product. At the same time, an effective metal sheet folding process can reduce the defective rate and the number of reworks, thereby improving production efficiency. The design of the bottom frame 62 and the buffer frame 63 makes the metal sheet folding smoother and more stable, reducing uncertainties and problems in the production process, and helping to achieve efficient production. Preferably, the metal sheet is galvanized steel sheet.

[0059] Furthermore, in some specific embodiments, the frame body 1 is a second cavity structure. Specifically, the second cavity structure can be a full frame structure or a half frame structure.

[0060] When the second cavity structure is a full frame structure, one implementation method is: Figure 8 、 9 As shown, the second cavity structure may include a first supporting frame 10, a first vertical frame 11, a horizontal frame 12, and a second vertical frame 13. The first vertical frame 11, the horizontal frame 12, and the second vertical frame 13 together form the second cavity structure. Accordingly, the second vertical frame 13 and the load-bearing frame 60 jointly support the supporting frame, providing support force for the laminate 4 and good support stability. It should be noted that the second vertical frame 13 can be arranged vertically or vertically inclined, which is not specifically limited in this utility model.

[0061] The second implementation method is: Figure 1-7 As shown in FIG. 10 , the second cavity structure only includes a first supporting frame 10 , a first vertical frame 11 and a horizontal frame 12 . The first supporting frame 10 , the first vertical frame 11 , the horizontal frame 12 , and the bearing frame 60 together form the second cavity structure.

[0062] When the second cavity structure is a half frame structure, that is, Figure 11As shown, the second cavity structure only includes the first supporting frame 10, which has a simple structure and saves material costs.

[0063] by Figure 1 and Figure 12 The photovoltaic module frame shown is for comparative analysis:

[0064] First, use Ansys software to simulate the load conditions of the components, and the analysis results are as follows: Figure 13 、 14 The figure shows that under the same pressure and with the beam and pressure block installed in the same position, the maximum deformation displacement of the short side frame without A side is 20.78mm when subjected to a front pressure of 5400Pa, while the maximum deformation displacement of the traditional frame is 33.31mm. And when the frame without A side is subjected to a back pressure of 2400Pa, the maximum deformation displacement is 18.04mm, while the maximum deformation displacement of the traditional frame is 18.76mm. It can be seen that compared with the traditional frame, the frame without A side has a stronger load-bearing capacity.

[0065] Secondly, in order to evaluate the difference in steel material usage of the improved frame, the frame model was drawn with the help of SolidWorks software. The side area of ​​the two frames was calculated to obtain the side weight per meter of the frame. The calculation results show that the side area of ​​the traditional frame is 117.67mm 2 , the weight of rice is 9.24g / cm 2 ; The improved frame side area is 88.58mm 2 , the weight per meter is 6.96g / cm 2 Compared with the traditional frame, the improved frame has a smaller side area and a smaller weight per meter, which further indicates that the improved frame consumes less material.

[0066] Based on the above-mentioned photovoltaic module frame, the present invention further provides a photovoltaic module, comprising a laminate 4 and a frame mounted to the edge of the laminate 4, wherein at least one side of the laminate 4 has a frame that is the above-mentioned photovoltaic module frame, thereby achieving a full-screen, single-screen, or multi-screen A-side-free design for the photovoltaic module. The photovoltaic module provided by the present invention utilizes all of the technical solutions of all of the above-mentioned photovoltaic module frame embodiments, and thus possesses at least all of the beneficial effects brought about by the technical solutions of the above-mentioned photovoltaic module frame embodiments, which will not be further elaborated here.

[0067] The above further describes the present invention with the help of specific embodiments, but it should be understood that the specific description here should not be construed as limiting the essence and scope of the present invention. Various modifications made to the above embodiments by ordinary technicians in this field after reading this specification are all within the scope of protection of the present invention.
