The fabric layer 200 can also prevent moisture, dust or other pollutants in the external environment from invading the inside of the frame, thereby further prolonging the service life of the photovoltaic frame.

[0030] With reference to Figure 1 , the x-axis direction is the horizontal direction, the y-axis direction is the vertical direction, and the z-axis direction is the extension direction of the base body 100.

[0031] In some embodiments, referring to Figures 1-2 , the corner code mounting portion 110 comprises a first side edge 111, a second side edge 112, a third side edge 113 and a fourth side edge 114, the plane where the first side edge 111 and the third side edge 113 are located is perpendicular to the y-axis direction, the plane where the second side edge 112 and the fourth side edge 114 are located is perpendicular to the x-axis direction, the first side edge 111, the second side edge 112, the third side edge 113 and the fourth side edge 114 are connected in sequence to jointly form a mounting cavity 115, the mounting cavity 115 is used for mounting a corner code to connect two adjacent base bodies 100, and the two adjacent base bodies 100 are arranged perpendicularly to improve the structural stability.

[0032] In some embodiments, the photovoltaic panel mounting portion 120 comprises a first mounting edge 121 and a second mounting edge 122, the plane in which the first mounting edge 121 is located is arranged at an angle with the plane in which the second mounting edge 122 is located, for example, the plane in which the first mounting edge 121 is located is parallel to the plane in which the second side edge 112 is located, and the plane in which the second mounting edge 122 is located is parallel to the plane in which the second side edge 112 is located, the first mounting edge 121 and the second mounting edge 122 are used to fix and limit the photovoltaic panel, so that the photovoltaic panel can be stably mounted on the photovoltaic frame. The angle between the first mounting edge 121 and the second mounting edge 122 can be set to a right angle to ensure the firmness and stability of the photovoltaic panel mounting.

[0033] In some embodiments, the second mounting edge 122 is connected with the first side edge 111, so that the first mounting edge 121, the second mounting edge 122 and the first side edge 111 form a photovoltaic panel mounting groove 123. For example, the angle between the plane in which the second mounting edge 122 is located and the plane in which the first side edge 111 is located is a right angle, so as to better adapt to the installation of the photovoltaic panel, so that the photovoltaic panel is more stable.

[0034] In some embodiments, the first mounting edge 121 and the photovoltaic panel are glued to paste the photovoltaic panel with the first mounting edge 121, and the photovoltaic panel and the second mounting edge 122 are glued to paste the photovoltaic panel with the second mounting edge 122, the first mounting edge 121 can limit the photovoltaic panel in the photovoltaic panel mounting groove 123, avoid the photovoltaic panel shaking in the photovoltaic panel mounting groove 123, so that the photovoltaic panel is more stable after installation. The first mounting edge 121 can increase the contact area between the photovoltaic panel and the base body 100, improve the pasting effect, ensure that the photovoltaic panel will not fall off or loosen during use, thereby improving the overall reliability and safety of the photovoltaic frame.

[0035] In some embodiments, referring to Figures 1-2 , the first mounting edge 121 is provided with a groove 124 on the side facing the photovoltaic panel mounting groove 123, the extension direction of the groove 124 is the same as the extension direction of the base body 100, and the groove 124 is used to accommodate the glue applied when installing the photovoltaic panel, preventing the glue from overflowing and improving the bonding quality.

[0036] In some embodiments, the photovoltaic frame further comprises a protective layer 300 covering the outer surface of the fabric layer 200, the protective layer 300 can improve the corrosion resistance and weather resistance of the photovoltaic frame, further enhance the protection performance of the photovoltaic frame, such as waterproof, dustproof, ultraviolet protection, etc., and provide more comprehensive protection for the photovoltaic frame.

[0037] In some embodiments, the protective layer 300 can be provided 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 water resistance, moisture resistance, ultraviolet resistance, and oxidation resistance, and can effectively protect the photovoltaic frame from the erosion of the external environment, thereby prolonging the service life of the photovoltaic frame.

[0038] In some embodiments, referring to Figures 1-3 , the fabric layer 200 includes a plurality of fabric strips 201 extending in the same direction as the base 100. The plurality of fabric strips 201 are arranged at intervals on at least part of the outer surface of the base 100, at least part of the inner surface of the corner fitting mounting portion 110, and at least part of the groove wall of the photovoltaic panel mounting groove 123. In this way, the fabric layer 200 not only enhances the overall structural strength of the photovoltaic frame and improves its deformation resistance, but also improves the weather resistance and durability of the photovoltaic frame. The fabric layer 200 can effectively prevent moisture, dust, and other impurities from penetrating into the interior of the frame, thereby protecting the frame and the photovoltaic panel from the erosion of the external environment. The fabric strips 201 arranged at intervals can disperse the stress concentration of the photovoltaic frame when it is under stress, thereby further prolonging the service life of the photovoltaic frame. The interval arrangement of the fabric strips 201 makes the surface of the fabric layer 200 have a certain roughness, which facilitates the arrangement of the protective layer 300 on the outside of the fabric layer 200 and improves the adhesion and stability of the protective layer 300.

[0039] In some embodiments, referring to Figures 1-3 , the distance between adjacent fabric strips 201 is less than the width of the fabric strip 201. This design ensures that the fabric layer 200 has a certain roughness on its surface while maintaining sufficient structural strength. The small distance between the fabric strips 201 helps to form a dense network structure, which can effectively resist external pressure and deformation, thereby enhancing the overall stability of the photovoltaic frame. In addition, by setting the distance between adjacent fabric strips 201 to be less than the width of the fabric strip 201, the surface roughness of the fabric layer 200 can be further optimized, ensuring that the protective layer 300 can be firmly attached to the fabric layer 200 and is not easily detached or peeled off, thereby further improving the durability and reliability of the photovoltaic frame.

[0040] In some embodiments, referring to Figures 1-3 , a felt strip 203 is embedded in the interval between the fabric strips 201. The felt strip 203 can effectively fill the gap between the fabric strips 201 and improve the overall structural strength of the fabric layer 200. The felt strip 203 can be made of materials that are resistant to wear and corrosion. The provision of the felt strip 203 not only enhances the roughness of the fabric layer 200, allowing the protective layer 300 to be more closely attached to the fabric layer 200 and improving adhesion, but also absorbs and disperses the stress of the frame when it is under stress, preventing damage to the frame caused by stress concentration.

[0041] In some embodiments, referring to Figures 1-3 , the fabric strips 201 are provided with breaking points 202, on one hand, the continuity of the fabric strips 201 can be maintained to maintain the structural strength of the photovoltaic frame, on the other hand, the breaking points 202 provided on the fabric strips 201 can increase the roughness of the surface of the fabric layer 200, and the adhesion between the fabric layer 200 and the protective layer 300 can be significantly improved without affecting the structural strength of the photovoltaic frame.

[0042] In some embodiments, referring to Figures 1-3 , the breaking points 202 provided on the adjacent fabric strips 201 are different in position, and this differentiated setting of the breaking points 202 makes the fabric layer 200 have different stress dispersion capabilities in different areas, further improving the impact resistance and durability of the photovoltaic frame. By differentiating the position of the breaking points 202, the adhesion between the fabric layer 200 and the protective layer 300 can be improved under the premise of ensuring the structural strength, thereby ensuring the stability and reliability of the photovoltaic frame under various environmental conditions.

[0043] In some embodiments, referring to Figures 1-3 , the breaking points 202 are embedded with felt blocks 204, which further enhances the adhesion between the fabric layer 200 and the protective layer 300. Moreover, the felt blocks 204 themselves have a certain elasticity and toughness, which can compensate for the loss of structural strength caused by the breaking points 202 to a certain extent. At the same time, the felt blocks 204 can also absorb and disperse external force impact, reducing stress concentration, thereby further improving the impact resistance and durability of the photovoltaic frame. In addition, the embedded setting of the felt blocks 204 also makes them not easy to fall off the fabric layer 200, ensuring the long-term stability and reliability of the photovoltaic frame.

[0044] In some embodiments, the fabric strips 201 are provided as fiber bundles, which makes the fabric strips 201 have the characteristics of high strength and high modulus, and can significantly improve the load-bearing capacity and anti-deformation ability of the photovoltaic frame while maintaining the overall lightweight structure of the photovoltaic frame.

[0045] In some embodiments, the fabric layer 200 has a grammage greater than 150 g / m2 and less than 300 g / m2, which ensures that the fabric layer 200 has sufficient strength and durability, and also does not make the overall weight of the photovoltaic frame too heavy, thereby maintaining the lightweight and easy-to-install characteristics of the photovoltaic frame.

[0046] In some embodiments, the base body 100 is a fiber-reinforced composite material. The base body 100 is prepared by pultrusion molding, and the base body 100 made of fiber-reinforced composite material can reduce the structural weight of the photovoltaic frame and improve the durability of the photovoltaic frame.

[0047] Another exemplary embodiment of the present application provides a photovoltaic module, referring to Figures 1-2 The photovoltaic module comprises the photovoltaic frame, the corner code and the photovoltaic panel, wherein the photovoltaic frame is the photovoltaic frame as described above, the adjacent photovoltaic frames are fixedly connected through the corner code, and the photovoltaic panel is installed in the photovoltaic panel installation slot 123.

[0048] The photovoltaic module comprises four photovoltaic frames and four corner codes, the adjacent two photovoltaic frames are fixedly connected through one corner code, and the four photovoltaic frames are enclosed to form a rectangular ring frame arranged at the edge of the photovoltaic panel through the four corner codes. The four corner codes are arranged at the four corners of the rectangular ring frame respectively.

[0049] The fabric layer 200 is arranged on at least part of the outer surface of the base body 100, at least part of the inner surface of the corner code installation portion 110 and at least part of the groove wall of the photovoltaic panel installation slot 123 by the photovoltaic frame of the present application, which can improve the overall structural strength of the photovoltaic frame, increase the wear resistance and aging resistance of the photovoltaic frame, protect the photovoltaic frame from erosion and prolong the service life of the photovoltaic module.
