Abstract
Description
Technical Field
[0001] This application relates to the field of solar power generation technology, specifically to a photovoltaic frame. Background Technology
[0002] In solar photovoltaic (PV) power generation systems, the PV frame, as a crucial component of PV modules, plays a vital role in supporting and protecting the PV panels and facilitating installation. With the rapid development of the PV industry, increasingly higher demands are being placed on the performance and production efficiency of PV frames.
[0003] Traditional photovoltaic (PV) frames are typically constructed using a single material. This structure makes the frames insufficiently strong when facing complex operating environments, such as strong winds and blizzards, leading to deformation and breakage, which in turn affects the overall stability and lifespan of the PV modules.
[0004] In the production of some frames using composite materials, different molding processes for each material are required. During pultrusion, the process needs to be interrupted multiple times to add material. This process can easily lead to loose bonding between materials, affecting the overall performance of the frame. Traditional processes struggle to achieve efficient and low-cost production while maintaining frame strength. Utility Model Content
[0005] In order to overcome the above-mentioned shortcomings of the prior art, this application aims to provide a photovoltaic frame.
[0006] According to this application, a photovoltaic frame is provided, comprising:
[0007] The substrate includes a top plate, a mounting plate, a bottom plate, a first support plate, a second support plate, and a third support plate. The bottom plate, the first support plate, the mounting plate, and the second support plate are sequentially connected to form a corner bracket mounting part. The top plate and the third support plate are connected to form a photovoltaic panel mounting part. The second support plate is connected to the third support plate to connect the photovoltaic panel mounting part to the corner bracket mounting part.
[0008] webbing;
[0009] The top plate, the mounting plate, the bottom plate, the first support plate, and the third support plate are provided with the webbing on one of their inner or outer surfaces, and the second support plate is provided with the webbing on both its inner and outer surfaces.
[0010] In some embodiments of this application, at least two webbing strips are provided, wherein, on a cross section perpendicular to the length direction of the substrate, at least one webbing strip extends continuously along the outer surface of the top plate, the outer surface of the third support plate, the outer surface of the second support plate and the outer surface of the bottom plate, and at least another webbing strip extends continuously along the inner surface of the first support plate, the inner surface of the mounting plate and the inner surface of the second support plate.
[0011] In some embodiments of this application, at least three webbing strips are provided. On a cross section perpendicular to the length direction of the substrate, at least one webbing strip extends continuously along the outer surface of the top plate, the outer surface of the third support plate, the outer surface of the second support plate, and the outer surface of the bottom plate. At least one webbing strip extends continuously along the outer surface of the mounting plate and the outer surface of the first support plate. At least another webbing strip extends along the inner surface of the second support plate.
[0012] In some embodiments of this application, the free end of the top plate is provided with a hook, the webbing is disposed away from the hook, or the webbing covers part of the outer surface of the hook.
[0013] In some embodiments of this application, the inner surface of the top plate is provided with an adhesive groove.
[0014] In some embodiments of this application, the projection of the webbing on the top plate onto the bottom surface of the bottom plate overlaps the projection of the adhesive groove onto the bottom surface.
[0015] In some embodiments of this application, the base plate is provided with a mounting portion protruding in a direction away from the second support plate, and the webbing extends from the base plate to the mounting portion.
[0016] In some embodiments of this application, the extension direction of the webbing is consistent with the length direction of the substrate.
[0017] In some embodiments of this application, the webbing is woven from multiple strands of thread.
[0018] In some embodiments of this application, the photovoltaic frame further includes a protective layer that covers the surface of the webbing.
[0019] The advantages of this application are as follows: The top plate, mounting plate, bottom plate, first support plate, and third support plate experience relatively low stress. Installing webbing only on one of their inner or outer surfaces is sufficient to meet structural reinforcement requirements, effectively reducing the amount of webbing used and lowering raw material costs. Simultaneously, single-sided webbing simplifies the production process, reducing labor hours and complex operations during webbing installation, further reducing production costs and improving efficiency. The second support plate bears significant pressure within the entire photovoltaic frame structure. After the photovoltaic panel is installed, its weight is transferred to the second support plate through the mounting plate. Installing webbing on both the inner and outer surfaces of the second support plate greatly enhances the structural strength of this area. When subjected to external forces, the webbing can evenly distribute the pressure across the entire second support plate, preventing deformation or damage due to excessive localized stress, and significantly improving the second support plate's ability to withstand complex stress environments.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. It should be noted that, unless otherwise specified, the embodiments and feature vectors in the embodiments of this application can be arbitrarily combined with each other.
[0030] Traditional photovoltaic (PV) frames are typically constructed using a single material. This structure makes the frames insufficiently strong when facing complex operating environments, such as strong winds and blizzards, leading to deformation and breakage, which in turn affects the overall stability and lifespan of the PV modules.
[0031] In the production of some frames using composite materials, different molding processes for each material are required. During pultrusion, the process needs to be interrupted multiple times to add material. This process can easily lead to loose bonding between materials, affecting the overall performance of the frame. Traditional processes struggle to achieve efficient and low-cost production while maintaining frame strength.
[0032] To address the aforementioned issues, this application provides a photovoltaic frame, comprising: a substrate and webbing. The substrate includes a top plate, a mounting plate, a bottom plate, a first support plate, a second support plate, and a third support plate. The bottom plate, the first support plate, the mounting plate, and the second support plate are sequentially connected to form a corner bracket mounting portion. The top plate and the third support plate are connected to form a photovoltaic panel mounting portion. The second support plate is connected to the third support plate to connect the photovoltaic panel mounting portion and the corner bracket mounting portion. Webbing is provided on one of the inner or outer surfaces of the top plate, the mounting plate, the bottom plate, the first support plate, and the third support plate. Webbing is provided on both the inner and outer surfaces of the second support plate. By rationally arranging the webbing positions, webbing is placed on one of the inner or outer surfaces of the plate portion with less stress to save costs. Multiple webbings are placed on the second support plate, which is subject to greater pressure, to improve the structural strength of the second support plate and ensure the overall structural stability of the photovoltaic frame.
[0033] An exemplary embodiment of this application provides a photovoltaic frame, see [link]. Figures 1-5 The photovoltaic frame includes a substrate 1 and a webbing 2.
[0034] The substrate 1 includes a top plate 11, a mounting plate 12, a bottom plate 13, a first support plate 14, a second support plate 15, and a third support plate 16. The bottom plate 13, the first support plate 14, the mounting plate 12, and the second support plate 15 are sequentially connected to form a corner bracket mounting part 18. The corner bracket mounting part 18 has a frame structure and is used to install corner brackets. For example, the photovoltaic frame can be provided with four substrates 1, which are connected by corner brackets. The corner brackets are inserted into the corner bracket mounting parts 18 of the substrates 1 to connect adjacent substrates 1 in pairs to form an enclosing structure. The four substrates 1, through the cooperation of the corner bracket mounting parts 18 and the corner brackets, achieve a reliable connection between adjacent substrates 1, forming a stable enclosing structure, ensuring the accuracy and firmness of the photovoltaic frame splicing, and improving the overall stability of the photovoltaic module.
[0035] The top plate 11 and the third support plate 16 are connected to form a photovoltaic panel mounting part 17. The photovoltaic panel mounting part 17 is L-shaped, and the photovoltaic panel is installed in the photovoltaic panel mounting part 17. The second support plate 15 is disposed away from the bottom plate 13 relative to the third support plate 16, and the second support plate 15 is connected to the junction of the third support plate 16 and the mounting plate 12. In a cross-section perpendicular to the extension direction of the substrate 1, the second support plate 15 is connected to the third support plate 16, and the extension directions of the second support plate 15 and the third support plate 16 are the same. The second support plate 15 is connected to the third support plate 16 to connect the photovoltaic panel mounting part 17 and the corner bracket mounting part 18.
[0036] In this design, webbing 2 is provided on one of the inner or outer surfaces of the top plate 11, mounting plate 12, bottom plate 13, first support plate 14, and third support plate 16, while webbing 2 is provided on both the inner and outer surfaces of the second support plate 15. The stress on the top plate 11, mounting plate 12, bottom plate 13, first support plate 14, and third support plate 16 is relatively small; providing webbing 2 on only one of their inner or outer surfaces is sufficient to meet their structural reinforcement requirements, thereby effectively reducing the amount of webbing 2 used and lowering raw material costs. Simultaneously, providing webbing 2 on only one side simplifies the production process, reduces labor hours and complex operations during webbing laying, further lowering production costs and improving production efficiency.
[0037] The second support plate 15 bears significant pressure within the entire photovoltaic frame structure. After the photovoltaic panel is installed, its weight is transferred to the second support plate 15 through the mounting plate 12. Furthermore, in severe weather conditions such as strong winds and blizzards, the second support plate 15 must withstand additional lateral and vertical forces. Therefore, webbing 2 is installed on both the inner and outer surfaces of the second support plate 15, greatly enhancing the structural strength of this area. When subjected to external forces, the webbing 2 can evenly distribute the pressure across the entire second support plate 15, preventing deformation or damage due to excessive localized stress, and significantly improving the second support plate 15's ability to withstand complex stress environments.
[0038] In some embodiments, see Figure 2 At least two webbing strips 2 are provided. In a cross section perpendicular to the length direction of the base 1, at least one webbing strip 2 extends continuously along the outer surface of the top plate 11, the outer surface of the third support plate 16, the outer surface of the second support plate 15 and the outer surface of the bottom plate 13. At least another webbing strip 2 extends continuously along the inner surface of the first support plate 14, the inner surface of the mounting plate 12 and the inner surface of the second support plate 15.
[0039] In this embodiment, at least two continuously extending webbing strips 2 are provided on the inner or outer surface of the substrate 1. This ensures that each plate of the top plate 11, mounting plate 12, bottom plate 13, first support plate 14, second support plate 15, and third support plate 16 is provided with webbing strips 2, thereby strengthening the overall structural strength of the photovoltaic frame. When the photovoltaic frame is subjected to external forces, these continuously extending webbing strips 2 can evenly transmit stress to various parts of the substrate 1, effectively avoiding deformation or even damage caused by localized stress concentration. Webbing strips 2 are provided on both the inner and outer surfaces of the second support plate 15, greatly enhancing the structural strength of this part. When subjected to external forces, the webbing strips 2 can evenly distribute the pressure to the entire second support plate 15, avoiding deformation or damage due to excessive localized stress, and significantly improving the ability of the second support plate 15 to cope with complex stress environments.
[0040] In this embodiment, the pultrusion process only requires one addition of webbing to complete the pultrusion molding process of the substrate 1, avoiding the need for multiple additions of webbing, improving production efficiency, and facilitating the efficient production of photovoltaic frames.
[0041] In some embodiments, see Figure 3 At least three webbing 2 are provided. On a cross section perpendicular to the length direction of the base 1, at least one webbing 2 extends continuously along the outer surface of the top plate 11, the outer surface of the third support plate 16, the outer surface of the second support plate 15 and the outer surface of the bottom plate 13 in sequence. At least one webbing 2 extends continuously along the outer surface of the mounting plate 12 and the outer surface of the first support plate 14 in sequence. At least another webbing 2 extends along the inner surface of the second support plate 15.
[0042] In this embodiment, at least three continuously extending webbing strips 2 are provided on the inner or outer surface of the substrate 1. This ensures that each plate of the top plate 11, mounting plate 12, bottom plate 13, first support plate 14, second support plate 15, and third support plate 16 is provided with corresponding webbing strips, thereby strengthening the overall structural strength of the photovoltaic frame. The webbing strips on both the inner and outer surfaces of the second support plate 15 significantly enhance the structural strength of this area. When subjected to external forces, the webbing strips can evenly distribute the pressure across the entire second support plate 15, preventing deformation or damage due to excessive local stress, and significantly improving the ability of the second support plate 15 to withstand complex stress environments.
[0043] In some embodiments, see Figures 2-4 The free end of the top plate 11 is provided with a hook 4, which bends towards the inner surface of the top plate 11. The hook 4 can be used to connect with the photovoltaic panel. The webbing 2 is positioned to avoid the hook 4 in order to ensure the elasticity of the hook 4, thereby facilitating the elastic engagement between the hook 4 and the photovoltaic panel. Secondly, the photovoltaic panel and the photovoltaic frame will undergo a certain displacement due to thermal expansion and contraction. At this time, the elasticity of the hook 4 can effectively buffer the displacement changes, prevent structural damage caused by rigid connection, and further enhance the structural stability and reliability of the photovoltaic frame.
[0044] In some embodiments, the webbing 2 covers part of the outer surface of the hook 4, which on the one hand ensures the elasticity of the hook 4 and facilitates the hook 4 to snap onto the photovoltaic panel. On the other hand, the webbing covering part of the outer surface of the hook 4 increases the friction between the hook 4 and the photovoltaic panel after connection, making the connection more secure.
[0045] In some embodiments, the inner surface of the top plate 11 is provided with an adhesive groove 5, the extension direction of the adhesive groove 5 is consistent with the length direction of the substrate 1, the adhesive groove 5 is used to contain the adhesive applied during the installation of the photovoltaic panel, prevents the adhesive from overflowing, and improves the bonding quality.
[0046] In some embodiments, the projection of the webbing 2 on the bottom surface of the top plate 11 onto the bottom surface of the bottom plate 13 covers the projection of the adhesive groove 5 onto the bottom surface. In this case, the webbing provides additional structural support for the area of the adhesive groove 5, improves the structural strength of the adhesive groove location, prevents cracks or deformations caused by excessive local stress at the location of the adhesive groove 5, and enhances the overall stability of the frame.
[0047] In some embodiments, the base plate 13 has a mounting portion 19 protruding away from the second support plate 15. The mounting portion 19 protrudes from the first support plate 14. The webbing 2 extends from the base plate 13 to the mounting portion 19, enhancing the structural strength of the mounting portion 19. When subjected to external force, the webbing can evenly distribute the stress borne by the mounting portion 19 to the base plate 13 and the entire photovoltaic frame structure, preventing the mounting portion 19 from breaking or deforming due to excessive local stress. This ensures that the photovoltaic frame can maintain a stable state under complex external force environments, guaranteeing the normal operation of the photovoltaic module.
[0048] In some embodiments, the extension direction of the webbing 2 is consistent with the length direction of the substrate 1, making the laying of the webbing 2 on the inner and outer surfaces of the substrate 1 smoother and effectively improving production efficiency. When external force is applied to the photovoltaic frame, since the webbing is consistent with the length direction of the substrate 1, it can more efficiently transmit and disperse stress in the length direction of the substrate 1, avoid local stress concentration, and enhance the support strength of the photovoltaic frame.
[0049] In some embodiments, the webbing 2 is woven from multiple threads to form a woven structure. When an external force is applied to the photovoltaic frame, it can disperse stress in the extension direction of the multiple threads, thereby enhancing the structural strength and support strength of the photovoltaic frame.
[0050] In some embodiments, see Figure 5 The multiple weave lines include multiple first weave lines 21 and multiple second weave lines 22. The multiple first weave lines 21 are arranged side by side, and the extension direction of the multiple first weave lines 21 is consistent with the length direction of the substrate 1. The multiple second weave lines 22 are arranged side by side along the extension direction of the first weave lines 21, so that when an external force is applied to the photovoltaic frame, the external force is transmitted along the length direction of the substrate 1 through the first weave lines 21, and the external force is dispersed and transmitted along the extension direction of the multiple second weave lines 22, so that the stress is distributed throughout the photovoltaic frame and stress concentration is avoided.
[0051] In some embodiments, multiple first threads 21 are arranged side by side within the same webbing, and the multiple first threads 21 include at least a first parallel thread 211, a second parallel thread 212 and a third parallel thread 213 arranged sequentially adjacent to each other.
[0052] The second thread 22 passes from the upper side of the first parallel thread 211 to the lower side of the second parallel thread 212, and from the lower side of the second parallel thread 212 to the upper side of the third parallel thread 213. Multiple first threads 21 and multiple second threads 22 are woven together in this manner to form the webbing 2. The multiple first threads 21 and second threads 22 interweave to form a tight and stable mesh structure. The first parallel threads 211, second parallel threads 212, and third parallel threads 213 in the first thread 21 have enhanced synergy due to the interlacing connection of the second threads 22. When the webbing is subjected to external force, the force is evenly distributed to each first thread 21 through the second threads 22, preventing a single thread from breaking due to excessive tension. This results in higher overall tensile strength for the webbing, enabling it to better cope with the stresses experienced by the photovoltaic frame under various operating conditions.
[0053] In some embodiments, the plane containing the second thread 22 is perpendicular to the first thread 21, so that the first thread 21 and the second thread 22 can be woven together to form the webbing 2.
[0054] In some embodiments, see Figure 4 The photovoltaic frame also includes a protective layer 3, which covers the surface of the substrate 1 and can improve the corrosion resistance and weather resistance of the photovoltaic frame.
[0055] The protective layer 3 can be set as a paint layer or a nylon layer. The paint layer is made of paint, and the nylon layer is made of nylon. Paint and nylon have good waterproof, moisture-proof, UV-proof, and oxidation-proof properties, which can effectively protect the photovoltaic frame from external environmental erosion and extend its service life.
