Description
Technical Field
[0001] This utility model relates to the field of solar power generation technology, and in particular to a frame and photovoltaic module. Background Technology
[0002] Laminates and frames are the two core components of traditional photovoltaic (PV) modules. The laminate, composed of front glass, encapsulating film, solar cells, and backsheet glass, is primarily responsible for photoelectric conversion. The frame, acting as a structural support framework, tightly wraps around the edges of the laminate, providing sufficient mechanical strength. Traditional frames are typically structurally higher than the laminate, making it easy for dust, grit, snow, and other contaminants to accumulate on the inner side of the frame, creating hard-to-clean corners and severely impacting the power generation efficiency of the PV module. Furthermore, under external mechanical loads such as wind pressure and snow accumulation, stress tends to concentrate at the contact edges between the frame and the laminate, significantly increasing the risk of the laminate bursting. Therefore, effectively addressing the challenges of dust prevention and stress concentration has become a crucial challenge driving the technological iteration of PV module structures.
[0003] To address this issue, the industry has proposed a full-screen structure, which offers the dual advantages of eliminating dust accumulation dead zones and avoiding stress concentration under normal conditions. However, when faced with extreme natural environments such as high wind pressure or heavy snow loads, the full-screen structure exhibits relatively insufficient bending and torsional resistance, posing a severe challenge to its load-bearing capacity. Utility Model Content
[0004] The purpose of this utility model is to provide a frame and a photovoltaic module. The frame body has two upper and lower chambers distributed vertically, and the side pressure frame abuts against the side of the frame body away from the laminate. Through the double-chamber structure and lateral support, the load-bearing capacity of the frame is comprehensively improved, and the technical problem of insufficient load-bearing capacity of the frame of existing photovoltaic modules is solved.
[0005] To achieve the above objectives, this utility model provides a frame, comprising:
[0006] The frame body is located between the laminate and the support. The frame body has an upper bearing plate at one end near the laminate. One end of the upper bearing plate has a support part that abuts against the bottom surface of the laminate, and the other end has a protruding stop part that abuts against the side of the laminate. The upper surface of the laminate is flush with the upper surface of the stop part. In the vertical direction from the laminate to the support, the frame body has two upper chambers and a lower chamber that are distributed vertically.

[0008] In some embodiments, both the upper chamber and the lower chamber have trapezoidal cross-sections; the frame body includes:
[0009] The lower support plate is tightly attached to the bracket.

[0011] V-shaped side plate, the V-shaped side plate is connected between the upper bearing plate and the lower support plate, and the V-shaped side plate protrudes towards the side support plate to form a bent protrusion;
[0012] The intermediate stiffening plate is fixed between the bending protrusion and the side support plate, and the intermediate stiffening plate, the upper bearing plate and the lower support plate are parallel to each other.
[0013] In some embodiments, both the upper chamber and the lower chamber have triangular cross-sections; the frame body includes:
[0014] The lower support plate is tightly attached to the bracket.
[0015] The first support plate connects the upper bearing plate and the lower support plate.
[0016] The second support plate is connected between the upper bearing plate and the lower support plate, and the second support plate is arranged crosswise with the first support plate.
[0017] In some embodiments, the cross-sectional area of the upper chamber is smaller than that of the lower chamber; and / or, the height of the upper chamber is the same as the height of the lower chamber, with the ratio of the two being in the range of 0.55-0.75.
[0018] In some embodiments, the side pressure frame includes a single-sided pressure frame disposed on one side of a single laminate, the single-sided pressure frame comprising:
[0019] The fastening plate abuts against the bracket and is fixed to the bracket by connecting bolts;
[0020] The lower pressure plate and the fastening plate are arranged in a stepped manner; the lower support plate of the frame body extends to the side away from the laminate, and the lower pressure plate abuts against the extension;
[0021] Side pressure plate, the side pressure plate is connected to the lower pressure plate at an angle, and the side pressure plate abuts against the side of the frame body away from the laminate.
[0022] In some embodiments, the side pressure frame includes a double-sided pressure frame disposed between two adjacent laminates, the double-sided pressure frame comprising:
[0023] The fastening plate abuts against the bracket and is fixed to the bracket by connecting bolts;
[0024] Two lower pressure plates are respectively located on both sides of the fastening plate, and each lower pressure plate is stepped with the fastening plate; the lower support plate of the frame body extends to the side away from the laminate, and the lower pressure plate abuts against the extension.
[0025] Two side pressure plates are connected to two corresponding lower pressure plates, and each side pressure plate is connected to the connected lower pressure plate at an angle. The side pressure plates abut against the side of the frame body away from the laminate.
[0026] In some embodiments, a positioning pin and a positioning hole are provided between the lower pressure plate and the extension.
[0027] In some embodiments, both the lower pressure plate and the extension have toothed surfaces on their opposing surfaces.
[0028] In some embodiments, the support portion is bonded to the bottom surface of the laminate and the stop portion is bonded to the side surface of the laminate by an adhesive layer; the support portion is provided with a bottom overflow groove; and / or, the stop portion is provided with an upper overflow groove opposite to the upper support plate and a side overflow groove connected to the side surface of the laminate.
[0029] This utility model also provides a photovoltaic module, including a laminate and the aforementioned frame, wherein the laminate is disposed on the frame.
[0030] Compared to the prior art, this utility model optimizes the structure of the photovoltaic module frame. The optimized frame includes a frame body and a side pressure frame. The frame body is located between the laminate and the support. An upper support plate is provided at one end of the frame body near the laminate. One end of the upper support plate has a support part that abuts against the bottom surface of the laminate, and the other end has a protruding stop part that abuts against the side of the laminate. The upper surface of the laminate is flush with the upper surface of the stop part, thus creating a full-screen structure. This effectively eliminates the step formed by the traditional frame being higher than the laminate, and solves the problems of dust accumulation dead corners and stress concentration from the root.
[0031] Crucially, in the vertical direction from the laminate to the support, the frame body has two upper and lower chambers distributed vertically, which counteracts the single-chamber structure of traditional frames. The double-chamber structure increases the moment of inertia of the cross-section by efficiently distributing the material at the upper and lower edges of the cross-section away from the neutral axis. When subjected to the same bending moment from external loads such as wind and snow, the bending stress generated by the frame cross-section is reduced, and the bending strength and stiffness are improved simultaneously, thereby effectively improving the load-bearing capacity of the frame.
[0032] Furthermore, the side pressure frame is fixed to the bracket and abuts against the side of the frame body away from the laminate, providing strong lateral support for the frame body. This effectively restrains the lateral displacement and torsional deformation of the frame body when subjected to asymmetrical or lateral forces, and also enhances the load-bearing capacity of the frame.
[0033] Therefore, by optimizing the frame structure and through the synergistic design of the double-chamber structure and lateral support, this utility model constitutes a stable load-bearing system, thereby comprehensively improving the load-bearing capacity of the frame when facing extreme natural environments such as high wind pressure or heavy snow load.

[0051] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0052] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0053] This utility model embodiment provides a frame, as shown in the attached figure. Figure 1 As shown, the system includes a frame body 1 and a side pressure frame 4. The frame body 1 is located between the laminate 2 and the support 3, directly bearing and transmitting mechanical loads. An upper bearing plate 11 is provided at one end of the frame body 1 near the laminate 2. The side of the upper bearing plate 11 near the laminate 2 extends beyond the frame body 1, forming an extended support platform. This widened design directly increases the contact area between the upper bearing plate 11 and the laminate 2, enabling the upper bearing plate 11 to stably support the laminate 2 and evenly distribute the load borne by the laminate 2, effectively improving the reliability and safety of the frame body 1.
[0054] One end of the upper bearing plate 11 is provided with a support portion 111 that abuts against the bottom surface of the laminate 2, and the other end is provided with a stop portion 112 that abuts against the side surface of the laminate 2. The support portion 111 is responsible for bearing the vertical load of the laminate 2, and the stop portion 112 is responsible for restricting the lateral sliding of the laminate 2. The support portion 111 and the stop portion 112 achieve comprehensive constraint on the laminate 2, and achieve precise positioning and reliable fixation of the laminate 2.
[0055] The upper surface of the laminate 2 is flush with the upper surface of the stop part 112, forming a full-screen structure. This effectively eliminates the step formed by the traditional bezel being higher than the laminate 2. It not only avoids the accumulation of dust, snow and other pollutants to form dust dead corners, but also allows the external load to be evenly distributed through a smooth transition to avoid stress concentration, thus solving the problems of dust dead corners and stress concentration from the root.
[0056] Crucially, in the vertical direction from the laminate 2 to the support 3, the frame body 1 has two upper chambers 12 and lower chambers 13 distributed vertically, which counteract the single chamber of the traditional frame. The double-chamber structure increases the moment of inertia of the cross section by efficiently distributing the material at the upper and lower edges of the cross section away from the neutral axis. When subjected to the same bending moment generated by external loads such as wind and snow, the bending stress generated by the frame cross section is reduced, and the bending strength and stiffness are improved simultaneously, thereby effectively improving the load-bearing capacity of the frame.
[0057] Furthermore, the side pressure frame 4 is fixed to the bracket 3 and abuts against the side of the frame body 1 away from the laminate 2, providing strong lateral support for the frame body 1, effectively restraining the lateral displacement and torsional deformation of the frame body 1 when subjected to asymmetrical or lateral forces, and also improving the load-bearing capacity of the frame.
[0058] Therefore, by optimizing the frame structure and through the synergistic design of the double-chamber structure and lateral support, this utility model constitutes a stable load-bearing system, thereby comprehensively improving the load-bearing capacity of the frame when facing extreme natural environments such as high wind pressure or heavy snow load.
[0059] As a preferred embodiment, as shown in the appendix Figure 1 As shown, both the upper chamber 12 and the lower chamber 13 have trapezoidal cross sections, making the frame body 1 B-shaped. By increasing the moment of inertia of the cross section to improve bending strength, the trapezoidal shape can smoothly transfer and disperse stress by utilizing its unique inclined surface structure. This avoids stress concentration at the corners of traditional right-angle structures, reduces the risk of fatigue cracks under long-term alternating loads, and helps extend the service life of the frame body 1.
[0060] Specifically, the frame body 1 includes a lower support plate 14, a side support plate 15, a V-shaped side plate 16, and a middle stiffener 17. The lower support plate 14 is in close contact with the bracket 3. The two ends of the side support plate 15 are perpendicularly connected to the upper bearing plate 11 and the lower support plate 14, respectively. The V-shaped side plate 16 is connected between the upper bearing plate 11 and the lower support plate 14, and the V-shaped side plate 16 protrudes towards the side support plate 15 to form a bent protrusion. The middle stiffener 17 is fixed between the bent protrusion and the side support plate 15, and the middle stiffener 17, the upper bearing plate 11, and the lower support plate 14 are parallel to each other. The V-shaped side plate 16 includes an upper inclined plate and a lower inclined plate arranged at an angle. The upper inclined plate, the middle stiffening plate 17, the upper half of the side support plate 15 and the upper bearing plate 11 are connected in sequence to form an upper chamber 12. The lower inclined plate, the middle stiffening plate 17, the lower half of the side support plate 15 and the lower support plate 14 are connected in sequence to form a lower chamber 13.
[0061] It is particularly important to note that for the B-shaped frame body 1, the upper edge of the upper chamber 12 and the lower edge of the lower chamber 13 have the same width, so that the neutral axis of the frame body 1 is located in the center of the cross section. This ensures that the upper and lower sides of the frame body 1 have equal compressive and tensile strength, ensuring that the load is evenly distributed between the upper chamber 12 and the lower chamber 13, avoiding torsional tendencies caused by structural asymmetry, thereby improving the structural stability and load-bearing capacity of the frame.
[0062] As another preferred embodiment, see attached Figure 2As shown, both the upper chamber 12 and the lower chamber 13 have triangular cross-sections, giving the frame body 1 a funnel shape. By increasing the moment of inertia of the cross-section to improve bending strength, the triangle's geometry allows for the shortest path of mechanical force transfer, resulting in a lightweight design of the frame body 1 by saving materials. Furthermore, the load is smoothly transferred and distributed through the two inclined surfaces of the triangle, enhancing the frame body 1's resistance to deformation. In addition, the continuous inclined surfaces of the funnel-shaped profile also have drainage and self-cleaning functions, allowing rainwater or condensate to drain quickly along the inclined surfaces, eliminating water accumulation dead zones and reducing the risk of corrosion caused by humidity. They also prevent dust accumulation, facilitating long-term maintenance.
[0063] Specifically, the frame body 1 includes a lower support plate 14, a first support plate 18, and a second support plate 19. The lower support plate 14 is in close contact with the bracket 3. Both the first support plate 18 and the second support plate 19 are connected between the upper bearing plate 11 and the lower support plate 14. The second support plate 19 and the first support plate 18 are arranged intersectingly to form a funnel-shaped structure. The upper half of the first support plate 18, the upper half of the second support plate 19, and the upper bearing plate 11 are connected in sequence to form an upper chamber 12, and the lower half of the first support plate 18, the lower half of the second support plate 19, and the lower support plate 14 are connected in sequence to form a lower chamber 13.
[0064] It is particularly important to note that, for the funnel-shaped frame body 1, the upper edge width of the upper chamber 12 is 2 / 3 of the lower edge width of the lower chamber 13, forming an upper-contracting and lower-expanding structure, which lowers the structural center of gravity of the frame body 1 and effectively improves the overturning stability of the frame body 1.
[0065] In a preferred embodiment, the cross-sectional area of the upper chamber 12 is smaller than that of the lower chamber 13, and / or the ratio of the height of the upper chamber 12 to the height of the lower chamber 13 is in the range of 0.55-0.75, preferably 0.67, thus constructing a structure that is smaller at the top and larger at the bottom. This not only allows more material to be distributed in the area near the support 3, increasing the moment of inertia of the lower part of the structure and improving the bending stiffness, but also lowers the center of gravity of the frame body 1, enhancing the stability of the frame body 1 under lateral loads such as wind pressure.
[0066] As a preferred embodiment, as shown in the appendix Figure 1 and 3As shown, the side pressure frame 4 includes a single-sided pressure frame 41 disposed on one side of a single laminate 2. Specifically, the single-sided pressure frame 41 includes a fastening plate 401, a lower pressure plate 402, and a side pressure plate 403. The fastening plate 401 abuts against the bracket 3 and is fixed to the bracket 3 by connecting bolts 5, so that the single-sided pressure frame 41 is fixed on the support plate. The lower pressure plate 402 and the fastening plate 401 are arranged in a stepped manner; the lower support plate 14 of the frame body 1 extends to the side away from the laminate 2 and has an extension 141. The lower pressure plate 402 abuts against the extension 141, which firmly locks the frame body 1 onto the bracket 3, improving the lateral stability of the frame body 1 and enabling it to effectively resist the lateral shear force from the laminate 2 in harsh environments such as strong winds. The side pressure plate 403 is connected to the lower pressure plate 402 at an angle. The side pressure plate 403 abuts against the side of the frame body 1 away from the laminate 2, providing lateral support for the frame body. Combined with the vertical constraint provided by the lower pressure plate 402, it resists the upward lifting force and lateral shear force of the frame body 1, effectively improving the fixed stability of the frame body 1.
[0067] As another preferred embodiment, see attached Figure 4 As shown, the side pressure frame 4 includes a double-sided pressure frame 42 disposed between two adjacent laminates 2. Specifically, the double-sided pressure frame 42 includes a fastening plate 401, two lower pressure plates 402, and two side pressure plates 403. The fastening plate 401 abuts against the bracket 3 and is fixedly connected to the bracket 3 by connecting bolts 5. The two lower pressure plates 402 are respectively disposed on both sides of the fastening plate 401, and each lower pressure plate 402 is steppedly disposed with respect to the fastening plate 401. The lower support plate 14 of the frame body 1 extends to the side away from the laminate 2 and has an extension portion 141, with the lower pressure plate 402 abutting against the extension portion 141. The two side pressure plates 403 are respectively connected to the two lower pressure plates 402, and each side pressure plate 403 is angularly connected to the connected lower pressure plate 402, with the side pressure plate 403 abutting against the side of the frame body 1 away from the laminate 2.
[0068] It should be added that the tilt angle of the side pressure plate 403 should be adjusted adaptively according to the type of the frame body 1, so as to ensure that the side pressure plate 403 is parallel and abuts against the side of the frame body 1 away from the laminate 2.
[0069] As another preferred embodiment, see attached Figure 5 As shown, the single-sided pressure frame 41 includes a fastening plate 401 and a lower pressure plate 402. The fastening plate 401 abuts against the bracket 3 and is fixedly connected to the bracket 3 by connecting bolts 5. The lower pressure plate 402 is steppedly arranged with respect to the fastening plate 401, and the lower pressure plate 402 abuts against the extension 141 of the lower support plate 14. Alternatively, as shown in the attached diagram... Figure 6As shown, the double-sided pressure frame 42 includes a fastening plate 401 and two lower pressure plates 402. The fastening plate 401 abuts against the bracket 3, and each lower pressure plate 402 abuts against the extension 141 of the lower support plate 14. That is to say, both the single-sided pressure frame 41 and the double-sided pressure frame 42 omit the side pressure plate 403, yet still achieve reliable fixation of the frame body 1.
[0070] In a preferred embodiment, a positioning pin 4021 and a positioning hole are provided between the lower pressure plate 402 and the extension 141. This allows for quick and accurate lateral positioning of the frame body 1, avoiding installation errors caused by human error and improving the installation quality of the frame body 1. Furthermore, the positioning pin 4021 can bear the lateral shear force of the frame body 1, preventing the connecting bolts 5 between the fastening plate 401 and the bracket 3 from deforming or breaking due to excessive shear force, thus improving the fatigue life of the connecting bolts 5. Specifically, the positioning pin 4021 is located on the lower pressure plate 402, and the positioning hole is located in the extension 141. To prevent assembly interference between the positioning pin 4021 and the bracket 3, the bracket 3 can be provided with a clearance groove to avoid the positioning pin 4021.
[0071] In a preferred embodiment, both the lower pressure plate 402 and the extension 141 have toothed surfaces on their opposing surfaces. These toothed surfaces form several spherical protrusions, increasing the contact area between the lower pressure plate 402 and the extension 141 and reducing the pressure between their opposing surfaces. When the connecting bolt 5 applies preload, the toothed surfaces allow the opposing surfaces of the lower pressure plate 402 and the extension 141 to fully engage, forming a mechanical interlock. This improves anti-slip capability and shear resistance, effectively enhancing the stability and reliability of the connection between the side pressure frame 4 and the frame body 1.
[0072] In a preferred embodiment, the support portion 111 is bonded to the bottom surface of the laminate 2, and the stop portion 112 is bonded to the side surface of the laminate 2 via an adhesive layer. The support portion 111 is provided with a bottom overflow groove 1111; and / or, the stop portion 112 is provided with an upper overflow groove 1121 opposite to the upper support plate 11 and a side overflow groove 1122 connected to the side surface of the laminate 2. The bottom overflow groove 1111, the upper overflow groove 1121, and the side overflow groove 1122 effectively solve the sealing failure problem caused by poor glue overflow in the full-screen structure. During the glue application and pressing process, the overflow groove provides a preset flow channel and accommodation space for excess adhesive, and allows the adhesive to form an ideal sealing strip in the overflow groove, filling the installation gap between the laminate 2 and the frame body 1, and improving the corrosion resistance of the full-screen structure in harsh environments.
[0073] This utility model embodiment also provides a photovoltaic module, including a laminate 2 and the aforementioned frame, wherein the laminate 2 is disposed on the frame and has the same beneficial effects.
[0074] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.
[0075] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
