[0026] 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.
[0027] A photovoltaic (PV) power generation system includes PV panels and PV frames arranged around the PV panels to support them. However, existing PV frames are structurally inadequate, making them prone to deformation or even damage, which affects the lifespan and safety of the PV modules.
[0028] To address the aforementioned issues, this application provides a photovoltaic frame, comprising a substrate and a webbing. The substrate extends along a first direction and has mounting cavities for mounting corner brackets and mounting grooves for mounting photovoltaic panels. The webbing is embedded in the substrate and extends along the first direction. The webbing is woven from multiple strands of wire, each strand extending at an angle to the first direction to improve the structural strength of the photovoltaic frame in different directions and prevent deformation of the photovoltaic frame under stress.
[0029] An exemplary embodiment of this application provides a photovoltaic frame, see [link]. Figures 1-4 The photovoltaic frame includes a substrate 100 and a webbing 190. The substrate 100 extends along a first direction and has a mounting cavity 160 for mounting corner brackets and a mounting groove 170 for mounting photovoltaic panels.
[0030] Reference Figure 1The x-axis is the horizontal direction, the y-axis is the vertical direction, and the z-axis is the first direction.
[0031] For example, the photovoltaic frame may be provided with four substrates 100, which are connected by corner brackets. The corner brackets are inserted into the mounting cavity 160 of the substrates 100 to connect the substrates 100 in pairs to form an enclosing structure.
[0032] The webbing 190 is embedded within the substrate 100 and extends along a first direction. The webbing 190 is woven from multiple strands of wire, each strand extending at an angle to the first direction. Since the extension directions of the multiple strands are different from the first direction, the photovoltaic frame exhibits high structural strength in different directions, effectively improving the overall deformation resistance of the photovoltaic frame. In this embodiment, the combination of the webbing 190 and the substrate 100 further enhances the overall stability of the photovoltaic frame, extends its service life, and improves the safety of the photovoltaic system.
[0033] In some embodiments, see Figure 4 The photovoltaic frame comprises multiple wire harnesses, including a first wire harness 191 and a second wire harness 192. The extension direction of the first wire harness 191 forms a first angle α with respect to a first direction, and the extension direction of the second wire harness 192 forms a second angle β with respect to the first direction. The first angle α and the second angle β are different, allowing the extension directions of the first wire harness 191 and the second wire harness 192 to differ, thereby increasing the structural strength of the photovoltaic frame in more diverse directions and comprehensively enhancing its resistance to deformation. The different angles of the first wire harness 191 and the second wire harness 192 enable the photovoltaic frame to more effectively disperse and resist stress when subjected to external forces, avoiding deformation or damage caused by stress concentration. Furthermore, the first wire harness 191 and the second wire harness 192 can be interwoven within the base 100. This weaving method not only enhances the structural strength of the photovoltaic frame but also improves its overall stability and durability.
[0034] In some embodiments, a first included angle α greater than 10° and less than 40° can give the photovoltaic frame high structural strength in the extension direction of the first wire bundle 191. When the first included angle α is less than or equal to 10°, the photovoltaic frame cannot effectively resist external forces perpendicular to the first direction, which will affect the structural strength of the photovoltaic frame. When the first included angle α is greater than 40°, the closer the angle between the first wire bundle 191 and the first direction is to perpendicular, the smaller the increase in structural strength of the photovoltaic frame due to the first wire bundle 191. Moreover, when the first included angle α is greater than or equal to 40°, it will increase the manufacturing cost of the first wire bundle 191. Therefore, setting the first included angle α in the range of 10° to 40° can ensure the structural strength of the frame while taking into account the economics of manufacturing. In addition, the selection of this angle range can be flexibly adjusted according to the specific application scenario and usage requirements of the photovoltaic frame to meet the usage requirements in different environments.
[0035] In some embodiments, the second included angle β is greater than 10° and less than or equal to 90°, which enables the photovoltaic frame to have higher structural strength in the extension direction of the second wire bundle 192. This enhances the photovoltaic frame's ability to effectively resist external forces from the first direction, as well as its ability to effectively resist external forces from other directions, thereby improving the overall structural strength and stability of the photovoltaic frame. This design allows the photovoltaic frame to better adapt to various complex environments, improving the safety and lifespan of the photovoltaic module. Simultaneously, by reasonably setting the angle range of the first included angle α and the second included angle β, manufacturing costs can be reduced as much as possible while ensuring the structural strength of the photovoltaic frame, thus improving production efficiency.
[0036] In some embodiments, see Figures 1-2 The base 100 includes a base plate 110, a support plate 120, a pressure plate 150, a first side plate 130, and a second side plate 140. The plane containing the base plate 110, the support plate 120, and the pressure plate 150 is perpendicular to the y-axis direction, and the plane containing the first side plate 130 and the second side plate 140 is perpendicular to the x-axis direction. The base plate 110, the support plate 120, the first side plate 130, and the second side plate 140 together form a mounting cavity 160. The mounting cavity 160 is used to install corner brackets to connect two adjacent bases 100. The two adjacent bases 100 are arranged perpendicularly to improve structural stability.
[0037] Vertically, the first side plate 130 extends upward and protrudes from the support plate 120. A pressure plate 150 connects to the end of the first side plate 130 furthest from the base plate 110. The pressure plate 150, the first side plate 130, and the support plate 120 constitute a mounting groove 170 for the photovoltaic panel, used for mounting the photovoltaic panel. Adhesive is applied between the photovoltaic panel and the pressure plate 150 to bond them together. Similarly, adhesive is applied between the photovoltaic panel and the first side plate 130 to bond them together. The pressure plate 150 confines the photovoltaic panel within the mounting groove 170, preventing it from shifting and ensuring a more stable installation. Simultaneously, the pressure plate 150 increases the contact area between the photovoltaic panel and the substrate 100, improving the bonding effect and ensuring the photovoltaic panel will not detach or loosen during use, thereby enhancing the overall reliability and safety of the photovoltaic frame.
[0038] In some embodiments, a groove 180 is provided on the side of the pressure plate 150 facing the mounting groove 170. The groove 180 extends along a first direction and is used to accommodate the adhesive applied during the installation of the photovoltaic panel, preventing the adhesive from overflowing and improving the bonding quality.
[0039] In some embodiments, the webbing 190 is embedded in at least one of the base plate 110, support plate 120, pressure plate 150, first side plate 130, or second side plate 140. The webbing 190 can correspondingly improve the structural strength of the base plate 110, support plate 120, pressure plate 150, first side plate 130, or second side plate 140 in which the webbing 190 is embedded, making the overall structure of the photovoltaic frame more stable and enhancing the load-bearing capacity and deformation resistance of the photovoltaic frame. The webbing 190 can also increase the toughness of the photovoltaic frame, enabling the photovoltaic frame to better absorb and disperse impact force when subjected to external impact, thereby improving the impact resistance of the photovoltaic frame.
[0040] In some embodiments, at least two webbing strips 190 are embedded inside the base plate 110, support plate 120, pressure plate 150, first side plate 130, and second side plate 140, and the cross-sectional extension directions of the at least two webbing strips 190 are different. This design can further enhance the structural strength and stability of the photovoltaic frame in multiple directions. Specifically, the webbing strips 190 with different extension directions can more effectively resist pressure from different directions, improving the overall rigidity and durability of the photovoltaic frame. In addition, this design also helps to optimize the weight distribution of the photovoltaic frame, making it more balanced when bearing load and reducing the risk of damage caused by stress concentration.
[0041] In some embodiments, the webbing 190 is configured as a fiber bundle, which has the characteristics of high strength and high modulus, and can significantly improve its load-bearing capacity and deformation resistance while maintaining the overall lightweight structure of the photovoltaic frame.
[0042] In some embodiments, the basis weight of the webbing 190 is greater than 150 g / m² and less than 300 g / m². This ensures that the webbing 190 has sufficient strength and durability without making the overall weight of the photovoltaic frame excessive, thus maintaining the lightweight and easy-to-install characteristics of the photovoltaic frame. Simultaneously, the webbing 190 within this basis weight range can better integrate with components such as the base plate 110, support plate 120, pressure plate 150, first side plate 130, and second side plate 140, improving the overall stability and service life of the photovoltaic frame. Furthermore, this basis weight selection helps optimize production costs, enabling the photovoltaic frame to achieve higher cost-effectiveness while maintaining quality.
[0043] In some embodiments, see Figure 3 The photovoltaic frame also includes a protective layer 200, which covers the surface of the substrate 100 and can improve the corrosion resistance and weather resistance of the photovoltaic frame.
[0044] The protective layer 200 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.
