[0022] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0023] The following is for reference. Figures 1-6 This application describes a photovoltaic system, a photovoltaic mounting structure 10, and a combined pressure block 20 according to embodiments of the present application.

[0024] A photovoltaic (PV) system is a physical system that directly converts solar radiation energy into direct current (DC) electricity based on the photovoltaic effect. The core function of a PV system is to convert, transmit, and store photon energy into electrical energy.

[0025] The photovoltaic system includes a photovoltaic installation structure 10, photovoltaic laminates, and photovoltaic brackets.

[0026] The photovoltaic mounting structure 10 can be used to mount photovoltaic laminates onto photovoltaic brackets. The relevant structure of the photovoltaic mounting structure 10 will be described in detail below.

[0027] A photovoltaic laminate is a photoelectric conversion device in a photovoltaic system that converts light energy into electrical energy. The assembly method of the photovoltaic laminate with the photovoltaic mounting structure 10 will be described in detail below.

[0028] A photovoltaic (PV) mounting system is a supporting structural system for PV laminates. The main physical function of the PV mounting system is to bear and transfer static and dynamic loads to the foundation, while simultaneously positioning the PV laminates at an optimal solar illumination geometry. The assembly method between the PV installation structure 10 and the PV mounting system will be described in detail below.

[0029] This application also provides a photovoltaic installation structure 10.

[0030] like Figure 1 As shown, the photovoltaic installation structure 10 includes a frame 300, a combined pressure block 20, and a connector 400.

[0031] The frame 300 is a reinforcing and connecting component located on the outside of the photovoltaic laminate.

[0032] like Figure 2 As shown, the frame 300 has a mounting portion 330 and a mounting groove 340.

[0033] Mounting section 330 is the area used for connecting to the photovoltaic bracket.

[0034] like Figure 2 As shown, the mounting part 330 is provided with a third hole 331.

[0035] The third hole 331 provides a through passage for the connector 400. The wall of the third hole 331 can withstand the compressive and shear forces that the connector 400 may apply.

[0036] Mounting slot 340 can be used to install photovoltaic laminates.

[0037] The mounting groove 340 can accommodate and fix the edge of the photovoltaic laminate, providing mechanical support and protection for the photovoltaic laminate.

[0038] The mounting slot 340 can clamp the photovoltaic laminate in the thickness direction. In the thickness direction, when the photovoltaic laminate is subjected to force and tends to move in that direction, the frame 300 can apply a force along the thickness direction to the photovoltaic laminate, thereby effectively limiting the displacement of the photovoltaic laminate in the thickness direction. In the direction intersecting the thickness direction, when the photovoltaic laminate is subjected to force and tends to move in the direction intersecting the thickness direction, there is friction between the frame 300 and the photovoltaic laminate, thereby effectively limiting the displacement of the photovoltaic laminate in the direction intersecting the thickness direction.

[0039] like Figure 6 As shown, the combined pressure block 20 includes a first pressure block 100 and a second pressure block 200. The first pressure block 100 and the second pressure block 200 together form a first hole 246, and the second pressure block 200 has a first hole 245. The relevant structure of the combined pressure block 20 and its assembly method with the frame 300 will be described in detail below.

[0040] The connector 400 is a component that connects the photovoltaic mounting structure 10 to the photovoltaic bracket.

[0041] The connector 400 can achieve a reliable connection between the photovoltaic mounting structure 10 and the mounting bracket by fastening.

[0042] The connector 400 passes through the first hole 245, the third hole 331, and the second hole 246 in sequence.

[0043] The connector 400 presses the second pressing block 200, the frame 300 and the first pressing block 100 together by passing through the first hole 245, the third hole 331 and the second hole 246, and connects the entire photovoltaic installation structure 10 to the photovoltaic bracket.

[0044] This application also provides a combined pressure block 20.

[0045] like Figure 6 As shown, the combined pressing block 20 includes a first pressing block 100 and a second pressing block 200.

[0046] like Figure 1 As shown, the first pressure block 100 is used to clamp the frame 300 along the thickness direction.

[0047] The first pressing block 100 is located on the outside of the frame 300, and it can clamp the frame 300 in the thickness direction. In the thickness direction, when the frame 300 is subjected to force and tends to move in that direction, the first pressing block 100 can apply a force along the thickness direction to the frame 300, thereby effectively limiting the displacement of the frame 300 in the thickness direction. In the direction intersecting the thickness direction, when the frame 300 is subjected to force and tends to move in the direction intersecting the thickness direction, there is friction between the first pressing block 100 and the frame 300, thereby effectively limiting the displacement of the frame 300 in the direction intersecting the thickness direction.

[0048] like Figure 4 As shown, the first pressing block 100 has a first fitting structure 140 at one end of the outer side of the frame 300 (such as the mounting part 330 of the frame 300) for clamping.

[0049] That is, the first pressing block 100 is provided with a first fitting structure 140, which is located at one end of the outer side of the first pressing block 100 near the frame 300. For example, the first fitting structure 140 can be located at one end of the outer side of the first pressing block 100 near the mounting part 330 of the frame 300.

[0050] The first mating structure 140 can be complementary to the second mating structure 240 and can be used to mat with the second mating structure 240.

[0051] like Figure 1 As shown, the second pressure block 200 is used to clamp the frame 300 (such as the mounting part 330 of the frame 300) along the thickness direction.

[0052] That is, the second clamping block 200 is located on the outside of the frame 300. For example, the second clamping block 200 can clamp the mounting portion 330 of the frame 300 in the thickness direction. In the thickness direction, when the frame 300 is subjected to force and tends to move in the thickness direction, the second clamping block 200 can apply a force along the thickness direction to the frame 300, thereby effectively limiting the displacement of the frame 300 in the thickness direction. In the direction intersecting the thickness direction, when the frame 300 is subjected to force and tends to move in the direction intersecting the thickness direction, there is friction between the second clamping block 200 and the frame 300, thereby effectively limiting the displacement of the frame 300 in the direction intersecting the thickness direction.

[0053] like Figure 5 As shown, the second pressing block 200 has a second fitting structure 240 at one end of the outer side of the frame 300 (such as the mounting part 330 of the frame 300) that fits into the first fitting structure 140.

[0054] The second pressing block 200 is provided with a second fitting structure 240, which is located at one end of the second pressing block 200 near the outer side of the frame 300. For example, the second fitting structure 240 can be located at one end of the second pressing block 200 near the outer side of the mounting portion 330 of the frame 300. The second fitting structure 240 can complement the first fitting structure 140, and the second fitting structure 240 can be used to fit with the first fitting structure 140.

[0055] The first interlocking structure 140 and the second interlocking structure 240 can form a geometric interlock, increasing the contact area between the first pressure block 100 and the second pressure block 200. When the first pressure block 100 and the second pressure block 200 are subjected to shear loads such as external wind pressure, the force can be directly transmitted through the interlocking surfaces of the first interlocking structure 140 and the second interlocking structure 240, rather than relying solely on friction, thereby enhancing the shear resistance and helping to achieve a stable connection between the first pressure block 100 and the second pressure block 200, reducing the risk of misalignment between the two first pressure blocks 100 and the second pressure block 200.

[0056] like Figure 6 As shown, the first pressing block 100 and the second pressing block 200 together form the second hole 246 in the mating area.

[0057] That is, the first pressing block 100 can form a partial second hole 246 in the first fitting structure 140, and the second pressing block 200 can form a partial second hole 246 in the second fitting structure 240. After the first fitting structure 140 and the second fitting structure 240 are fitted together, they can jointly form a second hole 246 in the fitting area.

[0058] The second hole 246 provides a through passage for the connector 400. The hole wall of the second hole 246 can withstand the compressive and shear forces that the connector 400 may apply.

[0059] like Figure 5 As shown, the second pressure block 200 has a first hole 245 adapted to be located on the inner side of the frame 300 (e.g., the mounting portion 330 of the frame 300).

[0060] The first hole 245 can be located on the inner side of the mounting part 330 of the frame 300.

[0061] The first hole 245 provides a through passage for the connector 400. The hole wall of the first hole 245 can withstand the compressive and shear forces that the connector 400 may apply.

[0062] In related technologies, an integral clamping block is used to hold the frame of the photovoltaic module, and the fastening force generated by the threaded connector penetrates two holes located on the clamping block and the frame respectively, realizing the connection between the photovoltaic mounting structure and the photovoltaic bracket. Because photovoltaic systems are constantly exposed to dynamic loads such as wind vibration and thermal expansion and contraction, the preload of the threaded connector is prone to decrease, leading to slight slippage between the clamping block and the frame. This slippage may cause the threaded connector to directly contact the hole wall of the clamping block or the hole wall of the frame, thus transforming the shear load originally borne by friction into shear force on the bolt shank and extrusion and tearing force on the threaded hole. Under this repeated shearing and extrusion, thread stripping or hole wall expansion or even cracking can easily occur, ultimately leading to connection failure and posing a safety risk to the entire photovoltaic module.

[0063] The photovoltaic mounting structure 10 provided in this embodiment adopts a split-type clamping block, that is, a first clamping block 100 and a second clamping block 200 that can be interlocked clamp the frame 300, and a connector 400 passes through the first hole 245, the third hole 331, and the first clamping block 100 and the second clamping block 200 together form a second hole 246 in the interlocking area. This design achieves a highly efficient geometric interlock by cooperating the first interlocking structure 140 and the second interlocking structure 240 on the first clamping block 100 and the second clamping block 200. This allows the photovoltaic mounting structure 10 to directly transmit shear force through the interlocking interlocking surfaces when subjected to shear loads, instead of relying solely on the friction force generated by the fastening of the connector 400, thereby enhancing the shear resistance of the photovoltaic mounting structure 10. The cooperation of the interlocking area increases the contact area between the first clamping block 100 and the second clamping block 200, allowing the load to be distributed more evenly.

[0064] Meanwhile, the connector 400 penetrates the three holes of the photovoltaic installation structure 10, which can increase the contact area of ​​the connector 400, disperse the lateral stress generated by wind load or vibration, reduce the load and stress concentration on the hole wall, and reduce the risk of connector 400 damage and hole wall tearing.

[0065] Even when the fastening capacity of the connector 400 is reduced due to external dynamic loads, the mechanical interlock formed by the first interlocking structure 140 and the second interlocking structure 240 can still achieve a relatively firm physical connection, which can effectively reduce the risk of separation between the first pressure block 100, the second pressure block 200 and the frame 300, and help the photovoltaic installation structure 10 to fix the photovoltaic module and transmit force.

[0066] This design distributes the load through the fastening of the connector 400 and the geometric interlocking of the mating area, protecting the connector 400 and the walls of the first hole 245, the third hole 331, and the second hole 246. This enhances the mechanical strength, durability, and stability of the photovoltaic installation structure 10, thereby improving the reliability and durability of the photovoltaic system during long-term operation.

[0067] The assembly process of the combined pressure block 20 provided in this embodiment is as follows: The second pressing block 200 clamps the mounting portion 330 of the frame 300, and aligns the first hole 245 with the third hole 331 on the mounting portion 330; the first pressing block 100 clamps the frame 300, and the first fitting structure 140 and the second fitting structure 240 on the second pressing block 200 are interlocked, and the second hole 246 is aligned with the third hole 331 and the first hole 245; the connector 400 is passed through the first hole 245, the third hole 331 and the second hole 246 in sequence, and the connector 400 is fastened to the photovoltaic bracket; the mounting groove 340 is aligned with the outer edge of the photovoltaic laminate, and the frame 300 clamps the photovoltaic laminate.

[0068] According to the combined pressure block 20 provided in the embodiments of this application, by using the first pressure block 100 and the second pressure block 200 that fit together to clamp the frame 300, geometric interlocking of the fitting area can be achieved, reducing the shear load borne by the connector 400, reducing stress concentration and tearing of the hole wall, enhancing the mechanical strength, durability and stability of the photovoltaic installation structure 10, thereby improving the reliability and durability of the photovoltaic system in long-term operation.

[0069] Correspondingly, according to the photovoltaic installation structure 10 provided in the embodiments of this application, by adopting the above-mentioned combined pressure block 20, the shear load borne by the connector 400 can be reduced, the stress concentration and tearing of the hole wall can be reduced, and the mechanical strength, durability and stability of the photovoltaic installation structure 10 can be enhanced, thereby improving the reliability and durability of the photovoltaic system in long-term operation.

[0070] Correspondingly, the photovoltaic system provided according to the embodiments of this application, by adopting the above-mentioned photovoltaic installation structure 10, can reduce the shear load borne by the connector 400, reduce stress concentration and tearing of the hole wall, enhance the mechanical strength, durability and stability of the photovoltaic installation structure 10, thereby improving the reliability and durability of the photovoltaic system in long-term operation.

[0071] In some embodiments, such as Figure 4 As shown, the first fitting structure 140 includes a first fitting segment 141, a first connecting segment 142 and a second fitting segment 144 connected in sequence, and the first connecting segment 142 has a first notch 143.

[0072] The first fitting structure 140 includes a first fitting segment 141, a first connecting segment 142, and a second fitting segment 144. The first fitting segment 141 is connected to one end of the first connecting segment 142, and the second fitting segment 144 is connected to the other end of the first connecting segment 142. The first notch 143 is located in the first connecting segment 142.

[0073] like Figure 5 As shown, the second fitting structure 240 includes a third fitting segment 241, a second connecting segment 242 and a fourth fitting segment 244 connected in sequence, and the second connecting segment 242 has a second notch 243.

[0074] The second fitting structure 240 includes a third fitting segment 241, a second connecting segment 242, and a fourth fitting segment 244. The third fitting segment 241 is connected to one end of the second connecting segment 242, and the fourth fitting segment 244 is connected to the other end of the second connecting segment 242. The second notch 243 is located in the second connecting segment 242.

[0075] like Figure 6 As shown, the first interlocking segment 141 and the third interlocking segment 241 are interlocked.

[0076] The interlocking convex-concave structure between the first interlocking segment 141 and the third interlocking segment 241 increases the contact area between the first pressure block 100 and the second pressure block 200, allowing the load to be distributed more evenly. The first interlocking segment 141 and the third interlocking segment 241 achieve geometric interlocking, effectively resisting shear and torsional forces, and reducing the risk of relative displacement or separation of the first pressure block 100 and the second pressure block 200 under stress.

[0077] like Figure 6 As shown, the second interlocking segment 144 interlocks with the fourth interlocking segment 244.

[0078] The interlocking convex-concave structure between the second interlocking segment 144 and the fourth interlocking segment 244 increases the contact area between the first pressure block 100 and the second pressure block 200, allowing the load to be distributed more evenly. The second interlocking segment 144 and the fourth interlocking segment 244 achieve geometric interlocking, effectively resisting shear and torsional forces, and reducing the risk of relative displacement or separation of the first pressure block 100 and the second pressure block 200 under stress.

[0079] like Figure 6 As shown, the first connecting segment 142 is aligned with the second connecting segment 242, and the first notch 143 and the second notch 243 together form the second hole 246.

[0080] That is, the first connecting segment 142 and the second connecting segment 242 can be aligned relatively flat, the first notch 143 of the first connecting segment 142 is opposite to the second notch 243 of the second connecting segment 242, and the first notch 143 and the second notch 243 can be joined together to form the second hole 246.

[0081] like Figure 6 As shown, the first interlocking segment 141 and the third interlocking segment 241 are both sawtooth structures, and / or the second interlocking segment 144 and the fourth interlocking segment 244 are both sawtooth structures.

[0082] That is, the first interlocking segment 141 and the third interlocking segment 241 can both be fitted with a serrated structure, and the second interlocking segment 144 and the fourth interlocking segment 244 can both be fitted with a serrated structure.

[0083] Alternatively, the first interlocking segment 141 and the third interlocking segment 241 may both be fitted with a serrated structure, but the second interlocking segment 144 and the fourth interlocking segment 244 may not be fitted with a serrated structure.

[0084] Alternatively, the second mating segment 144 and the fourth mating segment 244 may both be mated with a serrated structure, but the first mating segment 141 and the third mating segment 241 may not be mated with a serrated structure.

[0085] The serrated structure withstands the shear stress between the first pressure block 100 and the second pressure block 200, and transforms the shear force, which could easily lead to loosening, into compressive stress on the serrated tooth surface, thereby improving the shear resistance of the photovoltaic mounting structure 10. Simultaneously, the inclined tooth surfaces of the serrations will compress against each other when subjected to lateral forces. When there is a tendency for relative sliding between the first pressure block 100 and the second pressure block 200, the inclined tooth surfaces of the serrations can provide a large compressive force, thereby suppressing the relative displacement between the first pressure block 100 and the second pressure block 200, and improving the long-term stability and reliability of the photovoltaic mounting structure 10.

[0086] Of course, the first mating section 141 and the third mating section 241, and / or the second mating section 144 and the fourth mating section 244 can also be mated using dovetail groove structure or tenon and mortise structure, etc.

[0087] In some embodiments, such as Figure 4 As shown, the extension directions of the first interlocking segment 141 and the second interlocking segment 144 both intersect the extension direction of the first connecting segment 142.

[0088] That is, the extension direction of the first interlocking segment 141 intersects the extension direction of the first connecting segment 142, and the extension direction of the second interlocking segment 144 intersects the extension direction of the first connecting segment 142.

[0089] like Figure 5 As shown, the extension directions of the third interlocking segment 241 and the fourth interlocking segment 244 both intersect the extension direction of the first connecting segment 142.

[0090] That is, the extension direction of the third interlocking segment 241 intersects the extension direction of the first connecting segment 142, and the extension direction of the fourth interlocking segment 244 intersects the extension direction of the first connecting segment 142.

[0091] Thus, the extending directions of the first fitting structure 140 and the second fitting structure 240 can intersect, or the extending directions of the first fitting structure 140 and the second fitting structure 240 can be parallel but the first fitting structure 140 and the second fitting structure 240 are spaced apart. That is, the first fitting structure 140 is not located in the extending direction of the second fitting structure 240.

[0092] This staggered design can stagger the arrangement of the first interlocking structure 140 and the second interlocking structure 240, which is equivalent to setting two independent sets of constraint points that are not on the same axis. This can increase the torsional stiffness of the photovoltaic installation structure 10, improve the stability of the photovoltaic installation structure 10, and reduce the risk of preload loss or loosening of the connection caused by the torsion of the photovoltaic installation structure 10.

[0093] In some embodiments, such as Figure 4As shown, the first pressing block 100 includes a first segment 110, a second segment 120, and a third segment 130 that are bent and connected in sequence.

[0094] The first pressing block 100 includes a first segment 110, a second segment 120, and a third segment 130. The first segment 110, the second segment 120, and the third segment 130 are connected sequentially. The extension directions of the first segment 110 and the second segment 120 intersect, and the extension directions of the second segment 120 and the third segment 130 intersect.

[0095] like Figure 4 As shown, the first segment 110 and the third segment 130 are positioned opposite each other to clamp the outer side of the frame.

[0096] For example, the first segment 110 can be used to clamp one end of the frame 300 that is away from the mounting part 330, and the third segment 130 can be used to clamp the outer side of the mounting part 330.

[0097] Specifically, the first segment 110 can contact the end of the frame 300 opposite to the mounting portion 330, and the third segment 130 can contact the outer surface of the mounting portion 330. In the thickness direction, when the photovoltaic laminate is subjected to force and tends to move in the thickness direction, the first segment 110 or the third segment 130 can apply a force in the thickness direction to the photovoltaic laminate, thereby effectively limiting the displacement of the photovoltaic laminate along the thickness direction. In the direction intersecting the thickness direction, when the photovoltaic laminate is subjected to force and tends to move in the direction intersecting the thickness direction, there is friction between the first segment 110 and the photovoltaic laminate, or between the third segment 130 and the photovoltaic laminate, thereby effectively limiting the displacement of the photovoltaic laminate in the direction intersecting the thickness direction.

[0098] like Figure 4 As shown, the third segment 130 has a first interlocking structure 140 at the end opposite to the second segment 120.

[0099] That is, the end of the third segment 130 that is away from the second segment 120 may be provided with a first interlocking segment 141, a first connecting segment 142 and a second interlocking segment 144 connected in sequence.

[0100] like Figure 5 As shown, the second pressure block 200 includes a first part 210, a second part 220 and a third part 230 that are bent and connected in sequence.

[0101] The second pressing block 200 includes a first part 210, a second part 220, and a third part 230. The first part 210, the second part 220, and the third part 230 are connected sequentially. The extension directions of the first part 210 and the second part 220 intersect, and the extension directions of the second part 220 and the third part 230 intersect.

[0102] like Figure 5As shown, the first part 210 and the third part 230 are positioned opposite each other to clamp the border.

[0103] For example, the first part 210 can be used to clamp the inner side of the mounting part 330, and the third part 230 can be used to clamp the outer side of the mounting part 330.

[0104] Specifically, the first part 210 can contact the inner surface of the mounting part 330, and the third part 230 can contact the outer surface of the mounting part 330. In the thickness direction, when the mounting part 330 is subjected to force and tends to move in the thickness direction, the first part 210 or the third part 230 can apply a thickness-direction force to the mounting part 330, thereby effectively limiting the displacement of the mounting part 330 in the thickness direction. In the direction intersecting the thickness direction, when the mounting part 330 is subjected to force and tends to move in the direction intersecting the thickness direction, there is friction between the first part 210 and the mounting part 330, or between the third part 230 and the mounting part 330, thereby effectively limiting the displacement of the mounting part 330 in the direction intersecting the thickness direction.

[0105] like Figure 5 As shown, the third part 230 has a second fitting structure 240 at one end opposite to the second part 220.

[0106] The third part 230 may have a third interlocking segment 241, a second connecting segment 242 and a fourth interlocking segment 244 connected in sequence at one end away from the second part 220.

[0107] In some embodiments, such as Figure 4 As shown, the first interlocking structure 140 is spaced apart from the second segment 120.

[0108] That is, the first fitting segment 141, the first connecting segment 142, or the second fitting segment 144 of the first fitting structure 140 does not extend to the second segment 120. The serrated structure of the first fitting segment 141 or the third fitting segment 241 is not provided in the second segment 120, and the first notch 143 is also not provided in the second segment 120.

[0109] If the first interlocking structure 140 is not separated from the second segment 120, the wall surface of the sawtooth structure or the first notch 143 may form a rigid constraint point at the second segment 120, which is bent and connected to the third segment 130. This could lead to significant local shear stress and peeling stress at the connection point between the wall surface of the sawtooth structure or the first notch 143 and the second segment 120. Such stress concentration could cause fatigue or cracking of the wall material of the sawtooth structure or the first notch 143. Separating the first interlocking structure 140 from the second segment 120 reduces stress concentration, decreases the risk of damage or misalignment to the wall surface of the sawtooth structure and the first notch 143, protects the structural integrity of the first interlocking structure 140, and thus improves the reliability and durability of the photovoltaic system during long-term operation.

[0110] like Figure 5 As shown, the second interlocking structure 240 is spaced apart from the second part 220.

[0111] That is, the third fitting segment 241, the second connecting segment 242, and the fourth fitting segment 244 of the second fitting structure 240 do not extend to the second part 220. The serrated structure of the third fitting segment 241 or the fourth fitting segment 244 is not provided in the second part 220, and the second notch 243 is also not provided in the second part 220.

[0112] If the second interlocking structure 240 is not spaced from the second portion 220, the wall surface of the sawtooth structure or the second notch 243 may form a rigid constraint point at the second portion 220, which is bent and connected to the third portion 230. This could lead to significant local shear stress and peeling stress at the connection point between the wall surface of the sawtooth structure or the second notch 243 and the second portion 220. Such stress concentration could cause fatigue or cracking of the wall material of the sawtooth structure or the second notch 243. However, by separating the second interlocking structure 240 from the second portion 220, stress concentration can be reduced, minimizing the risk of damage or misalignment to the wall surface of the sawtooth structure and the second notch 243, protecting the structural integrity of the second interlocking structure 240, and thus improving the reliability and durability of the photovoltaic system during long-term operation.

[0113] In the photovoltaic installation structure 10 of this application embodiment, as Figure 4 As shown, the border 300 includes a first layer 310 and a second layer 320, with the second layer 320 covering at least a portion of the area outside the first layer 310.

[0114] That is, the photovoltaic frame 300 may not be made of a single material, but rather a composite of different materials. The second layer 320 may cover the entire first layer 310, or it may cover only a portion of the first layer 310.

[0115] like Figure 1 As shown, the first pressing block 100 and the second pressing block 200 clamp the second layer 320.

[0116] During installation, the first pressing block 100 and the second pressing block 200 used to fix the frame 300 directly contact and clamp the outer second layer 320, while at least a portion of the first layer 310 is covered by the second layer 320.

[0117] The second layer 320 has better aging resistance than the first layer 310. For example, the second layer 320 is more resistant to environmental factors such as ultraviolet rays, wind and rain, temperature differences or corrosion than the first layer 310.

[0118] In some embodiments, such as Figure 1 and Figure 2 As shown, the first layer 310 forms a mounting groove 340, and the second layer 320 has a flange 321 that covers the outer side of the mounting groove 340.

[0119] That is, the first layer 310 can directly contact and hold the photovoltaic module, and the second layer 320 is bent and covers the outer side of the first layer 310 near the mounting groove 340.

[0120] like Figure 2 As shown, the mounting portion 330 includes a first layer 310 and a second layer 320 sandwiched between the two sides of the first layer 310. Figure 3 As shown, the third hole 331 penetrates the first layer 310 and the second layer 320 sandwiched on both sides of the first layer 310.

[0121] The mounting portion 330 includes a portion of a first layer 310 and a portion of a second layer 320. The second layer 320 is bent and covers the outer edge of the first layer 310 near the mounting portion 330. The third hole 331 penetrates the first layer 310 and the second layer 320 that is bent and covers the first layer 310.

[0122] In this way, the second layer 320 is bent to cover the outer edge of the first layer 310 from the mounting groove 340 to the outer edge of the first layer 310 from the mounting portion 330. The outer side of the first layer 310 can be completely covered by the first layer 310, which can make full use of the second layer 320 with strong aging resistance to cover the first layer 310 and improve the overall structural performance of the frame 300.

[0123] In some embodiments, the first layer 310 is resin fiberglass and the second layer 320 is aluminum alloy.

[0124] That is, the frame 300 is made of composite material, the inner side of the frame 300 is resin fiberglass, and at least part of the resin fiberglass is covered by aluminum alloy.

[0125] Resin-reinforced glass fiber is a composite material made by embedding glass fiber as a reinforcing material into a synthetic resin matrix. It has high strength, low density, strong corrosion resistance, and excellent insulation, but its elastic modulus is relatively low, and long-term exposure to ultraviolet light may cause the surface resin to powder or fade.

[0126] Aluminum alloys are alloy materials formed by adding elements such as copper, magnesium, silicon, or manganese to aluminum. Aluminum alloys have moderate strength, good aging resistance, and good machinability and ductility.

[0127] In related technologies, the entire frame is made of resin fiberglass, and the pure resin fiberglass surface is directly clamped by clamping blocks. The resin fiberglass may experience surface crushing, wear, or micro-cracks due to stress concentration, which may lead to loosening of the connection over time. In addition, long-term exposure of resin fiberglass to ultraviolet light may pose a risk of chalking and fading.

[0128] In related technologies, the entire frame is made of aluminum alloy. Since aluminum alloy is a conductor, it may form a pathway for potential-induced degradation (PID), leading to a decrease in photovoltaic module power, requiring additional anti-PID equipment. In addition, aluminum alloy is expensive.

[0129] This embodiment employs an aluminum alloy structure that at least partially covers resin-coated fiberglass. This allows the fiberglass to support the main structural loads of the photovoltaic module. Its high specific strength and lightweight characteristics reduce the overall weight and transportation / installation costs of the photovoltaic mounting structure 10, while simultaneously improving the corrosion resistance and insulation of the frame 300, reducing the risk of electrochemical corrosion and PID (Potential Inertial Damping). The outer aluminum alloy layer utilizes its weather resistance and mechanical toughness to provide a reliable connection point for clamping the first clamping block 100 and the second clamping block 200, reducing potential stress concentration and wear problems on the resin-coated fiberglass surface. The dense oxide layer on the aluminum alloy surface effectively resists ultraviolet radiation and weathering, ensuring the long-term appearance integrity and environmental stability of the frame 300, thereby improving the reliability and durability of the photovoltaic mounting structure 10.

[0130] In some embodiments, at least one of the first hole 245, the third hole 331, and the second hole 246 is a threaded hole.

[0131] That is, the first hole 245, the third hole 331, and the second hole 246 can all be threaded holes; Alternatively, the first hole 245 and the third hole 331 can both be threaded holes, and the second hole 246 can be a smooth hole; Alternatively, the first hole 245 and the second hole 246 can both be threaded holes, and the third hole 331 can be a smooth hole; Alternatively, the third hole 331 and the second hole 246 can both be threaded holes, and the first hole 245 can be a smooth hole; Alternatively, the first hole 245 can be a threaded hole, and the third hole 331 and the second hole 246 can both be plain holes; Alternatively, the third hole 331 can be a threaded hole, and the first hole 245 and the second hole 246 can both be plain holes; Alternatively, the second hole 246 can be a threaded hole, while the first hole 245 and the third hole 331 can both be plain holes.

[0132] Connector 400 can be a threaded connector.

[0133] The connector 400 can be a bolt or screw, with external threads on its shank for mating with a threaded hole.

[0134] The first hole 245, the third hole 331, and the second hole 246 are aligned.

[0135] That is, the central axes of the first hole 245, the third hole 331, and the second hole 246 can coincide on the same straight line. In this way, the connector 400 can pass smoothly through the first hole 245, the third hole 331, and the second hole 246, with reduced obstruction.

[0136] The following is combined with Figures 1-6 The photovoltaic installation structure 10 of this application is described in an embodiment.

The frame 300 has a mounting portion 330, which includes the first layer 310 and the second layer 320 sandwiched on both sides of the first layer 310. The mounting portion 330 is provided with a third hole 331 that penetrates the first layer 310 and the second layer 320 sandwiched on both sides of the first layer 310.

Both the first fitting segment 141 and the second fitting segment 144 are serrated structures. The first connecting segment 142 has a first notch 143. The extending directions of the first fitting segment 141 and the second fitting segment 144 intersect the extending direction of the first connecting segment 142.

[0140] The second clamping block 200 includes a first portion 210, a second portion 220, and a third portion 230 connected in sequence, forming a second layer 320 for clamping the mounting portion 330 of the frame 300. The first portion 210 and the third portion 230 are disposed opposite each other. The first portion 210 is used to clamp the inner side of the mounting portion 330 and has a first hole 245.
