[0044] The present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0045] The specific structure is as follows: Figures 1 to 4 As shown.

[0046] This embodiment provides a fixing component for fixing the frame 1 of a photovoltaic module to a photovoltaic bracket 2. The fixing component includes: a fastening block, a first fastener, and a second fastener. The fastening block includes a clamping connection part 3 and a fixing connection part 4, and the clamping connection part 3 can clamp and fix the frame 1 of the photovoltaic module. The first fastener is used to connect the frame 1 of the photovoltaic module, the clamping connection part 3, and the photovoltaic bracket 2. The second fastener is used to connect the fixing connection part 4 and the photovoltaic bracket 2.

[0047] In this embodiment, the frame 1 of the photovoltaic module is clamped and fixed by the clamping connection part 3 on the fastening block. The frame 1, clamping connection part 3 and photovoltaic bracket 2 of the photovoltaic module are connected and fixed by the first fastener. The fixing connection part 4 and photovoltaic bracket 2 are connected and fixed by the second fastener. The fastening block is connected and fixed to the photovoltaic bracket 2 at two points. The multiple fixing points ensure the stability of the connection and the load is distributed to two points, resulting in strong load-bearing capacity. At the same time, the stress on the frame 1 of the photovoltaic module can be distributed to the clamping connection part 3 to avoid local concentration. This can improve the installation tightness of the photovoltaic module in harsh environments, meet the installation requirements in harsh environments, and expand the application range of the photovoltaic module.

[0048] In this embodiment, the clamping connection part 3 clamps and fixes the A side 16 and C side 17 of the frame 1 of the photovoltaic module to ensure the stability of the frame 1 of the photovoltaic module.

[0049] In this embodiment, the fastening block is integrally molded, which is convenient to manufacture and has a stable structure.

[0050] In the optional technical solution of this embodiment, the clamping connection part 3 includes a pressure plate 5, a support plate 6 and a side plate 7; the pressure plate 5 and the support plate 6 are both connected to the first side of the side plate 7, and the pressure plate 5 and the support plate 6 are arranged opposite to each other. A clamping space for clamping and fixing the frame 1 of the photovoltaic module is formed between the pressure plate 5 and the support plate 6. The first fastener is used to connect the frame 1 of the photovoltaic module, the support plate 6 and the photovoltaic bracket 2; the fixing connection part 4 is located on the second side of the side plate 7 away from the pressure plate 5 and the support plate 6.

[0051] In this embodiment, the first fastener passes through the C-side 17 of the frame 1 of the photovoltaic module and the support plate 6 to connect with the photovoltaic bracket 2, making the connection convenient and stable. The clamping connection part 3 consists of three plates: a pressure plate 5, a support plate 6, and a side plate 7, forming a U-shape. The overall structure is simple and the clamping effect is good.

[0052] In this embodiment, the clamping connection 3 can also be C-shaped, that is, the clamping connection 3 is formed by a bent plate, which also has a clamping function.

[0053] In the optional technical solution of this embodiment, an arc-shaped groove 8 is provided at the included angle between the pressure plate 5 and the side plate 7; and / or, an arc-shaped groove 8 is provided at the included angle between the support plate 6 and the side plate 7.

[0054] In this embodiment, the arc-shaped groove 8 allows for an expansion of the clamping space on the frame 1 of the photovoltaic module during installation, improving installation convenience and applicability, and significantly enhancing stress buffering effect. On one hand, the arc-shaped groove 8 eliminates stress concentration points at right angles, preventing fatigue and cracking caused by excessive stress accumulation; on the other hand, the movement space reserved in the arc-shaped groove 8 allows the clamping connection 3 to undergo slight elastic displacement under external forces such as strong winds and temperature changes, absorbing energy through deformation and reducing the overall impact force on the photovoltaic module, thereby effectively extending the service life and operational stability of the photovoltaic module.

[0055] In the optional technical solution of this embodiment, the pressure plate 5 is provided with an anti-slip structure on the side facing the support plate 6. The anti-slip structure abuts against the A-side 16 of the photovoltaic module frame 1. The anti-slip structure increases the friction between the pressure plate 5 and the A-side 16 of the photovoltaic module frame 1, ensuring the stability of clamping and effectively preventing the displacement of the photovoltaic module frame 1; and / or, the support plate 6 is provided with an anti-slip structure on the side facing the pressure plate 5. The anti-slip structure is used to abut against the C-side 17 of the photovoltaic module frame 1. The anti-slip structure increases the friction between the support plate 6 and the C-side 17 of the photovoltaic module frame 1, ensuring the stability of clamping and effectively preventing the displacement of the photovoltaic module frame 1.

[0056] In the optional technical solution of this embodiment, the anti-slip structure includes multiple spaced anti-slip ribs 9 along the direction from the first side to the second side of the side plate 7. The structure is simple and provides better anti-slip effect. The anti-slip ribs 9 tightly grip the surface of the photovoltaic module frame 1, enhancing the stability of the mechanical connection and increasing the friction between the clamping connection part 3 and the photovoltaic module frame 1, effectively resisting lateral displacement caused by external forces such as strong winds and blizzards. In extreme weather conditions, the anti-slip ribs 9 form a stable grip through multi-point contact, preventing loosening and ensuring that the photovoltaic module maintains a reliable connection for a long time, reducing the risk of reduced power generation efficiency due to connection failure. During compression, the anti-slip ribs 9 evenly distribute concentrated stress to a larger area of ​​the photovoltaic module frame 1, optimizing stress dispersion and avoiding local stress overload. The cross-section of the anti-slip ribs 9 can be triangular, trapezoidal, or arc-shaped. Its unique structure allows external forces to be gradually transmitted along the inclined surface of the anti-slip ribs 9, reducing direct impact on the photovoltaic module frame 1, effectively preventing deformation and cracking of the photovoltaic module frame 1, ensuring the structural integrity of the photovoltaic module in complex environments, and extending its service life. Meanwhile, the anti-slip ribs 9 and the arc-shaped grooves 8 work together to enhance the adaptability of the clamping connection part 3 to the frame 1 of photovoltaic modules with different surface roughness, enabling secure installation without special treatment of the frame 1 of the photovoltaic modules. During installation, the anti-slip ribs 9 automatically embed into the tiny grooves on the frame 1 of the photovoltaic modules, quickly positioning and locking them, reducing the difficulty and time cost of manual installation, while ensuring that photovoltaic modules of different batches and specifications can achieve stable and reliable connection.

[0057] This embodiment is not limited to this; the anti-slip structure can also be an anti-slip strip, anti-slip bumps, or anti-slip pad, etc., as long as it meets the requirements.

[0058] In the optional technical solution of this embodiment, the fixed connection part 4 includes a support plate 10 and a connecting plate 11; the support plate 10 is connected to the clamping connection part 3 through the connecting plate 11, and the support plate 10 is used to abut against the photovoltaic bracket 2; the second fastener is used to connect the connecting plate 11 and the photovoltaic bracket 2.

[0059] In this embodiment, the second fastener passes through the connecting plate 11 and connects to the photovoltaic bracket 2, while the support plate 10 abuts against the photovoltaic module. There is a hollow space between the support plate 10 and the photovoltaic bracket 2, resulting in a lighter overall structure and saving materials during manufacturing. However, it is not limited to this; the fixed connection part 4 can also be a fixed block, i.e., there is no hollow space.

[0060] In the optional technical solution of this embodiment, the end of the support plate 10 that abuts against the photovoltaic bracket 2 is provided with an abutment seat 12; the width of the abutment seat 12 is greater than the width of the support plate 10. This increases the abutment area and ensures the stability of the abutment.

[0061] In this embodiment, the first fastener and the second fastener may be rivets or pins.

[0062] In the optional technical solution of this embodiment, an anti-loosening structure is also included; the first fastener includes a first bolt 13, the clamping connection part 3 is provided with a first threaded connection hole, and the thread of the first bolt 13 is connected to the thread of the first threaded connection hole through the anti-loosening structure to prevent the connection between the first bolt 13 and the first threaded connection hole from becoming loose; and / or; the second fastener includes a second bolt 14, the fixing connection part 4 is provided with a second threaded connection hole, and the thread of the second bolt 14 is connected to the thread of the second threaded connection hole through the anti-loosening structure to prevent the connection between the second bolt 14 and the second threaded connection hole from becoming loose.

[0063] In this embodiment, the first bolt 13 can be directly screwed onto the photovoltaic bracket 2 to achieve connection, or the first fastener can also include a first nut that matches the first bolt 13, with the first bolt 13 passing through side C 17 and being connected and fixed to the photovoltaic bracket 2 by the first nut; the second bolt 14 can be directly screwed onto the photovoltaic bracket 2 to achieve connection, or the second fastener can also include a second nut that matches the second bolt 14, with the second bolt 14 passing through the photovoltaic bracket 2 and being connected and fixed by the second nut.

[0064] In the optional technical solution of this embodiment, the anti-loosening structure is a helical spring 15. The helical spring 15 can be screwed into the threaded connection hole by engaging with the threaded connection hole, and the bolt thread can be screwed into the helical spring 15 by engaging with the helical spring 15. The helical spring 15 is made of a high-elasticity memory alloy. Arranged along the bolt axially, the helical spring 15 forms a composite elastic structure with the threaded connection hole, significantly improving anti-loosening performance. It can maintain tightness under vibration, and also provides cushioning to increase bolt lifespan and reduce maintenance. Furthermore, compared to traditional external anti-loosening structures, the embedded helical spring 15 does not change the external dimensions of the bolt, and can be adapted to existing standard nuts and connected components. By dispersing stress, it avoids local overload, reduces fatigue damage caused by long-term stress, delays structural aging, and effectively extends the service life of the fastening block and the connected components. In addition, the helical spring 15 undergoes elastic deformation under pressure, accumulating elastic potential energy; under the thrust of the helical spring 15, it expands outward, tightly adhering to the outer wall of the bolt and the inner wall of the threaded connection hole, forming multi-directional friction. The special structural design provides buffer protection for photovoltaic modules and bolts, reducing wear caused by vibration and avoiding problems such as bolt loosening and hole deformation caused by high-frequency vibration. This extends the service life of the overall fastening system, reduces the frequency of maintenance and replacement, and lowers the overall operating cost.

[0065] In this embodiment, facing the lateral impact force brought by strong winds, the clamping connection 3 and the fixed connection 4 of the fastening block can form a staggered support, creating a synergistic protection against lateral wind forces. By absorbing wind energy through the arc-shaped groove 8 and the composite elastic structure, the lateral wind resistance of the photovoltaic module can be increased by more than 40%, effectively resisting extreme weather conditions. The fastening block can achieve multi-directional stress dispersion reinforcement, performing secondary decomposition of complex external forces such as oblique and torsional forces, further reducing stress concentration at the threaded connection holes. Finite element analysis and simulation tests have verified that this reduces the risk of tearing at the threaded connection holes and blocks the cascading damage path.

[0066] In this embodiment, the composite material of the fastening block has good weather resistance and corrosion resistance, and can resist the erosion of external environments such as ultraviolet rays, rainwater, and salt spray, preventing the fastening block from failing due to oxidation and acid and alkali corrosion, and maintaining stable performance even in harsh environments.

[0067] In this embodiment, the frame 1 of the photovoltaic module is fixed to the photovoltaic bracket 2 by fastening blocks. When the photovoltaic module is subjected to wind force, the displacement of the photovoltaic module is reduced compared with the prior art. It also provides more protection for the photovoltaic module and bolts, better resists lateral stress concentration, and prevents the failure of the fastening blocks from causing other chain problems such as tearing of the threaded connection holes, which would ultimately lead to the failure of the photovoltaic module.

[0068] In this embodiment, the fastening block not only buffers the direct impact of external forces on the photovoltaic module, but also reduces frictional loss between the bolt and the threaded connection hole by wrapping the bolt structure with the helical spring 15, forming double protection, reducing the risk of fastening block failure, preventing the threaded connection hole from tearing due to stress tension, and eliminating chain damage. The fixing component is compatible with existing purlins, enabling rapid installation and adjustment, shortening the cycle and reducing costs. The accessories are simple to process, and the double protection prevents failure. Under negative wind pressure conditions, it reduces the leverage effect; increases the contact area, reduces local pressure, and when used with elastic gaskets, it can effectively buffer fatigue damage caused by high-frequency vibration, improving the overall stability of the photovoltaic module while extending its service life.

[0069] This embodiment is not limited to this; the anti-loosening structure can also be formed by raw rubber tape, that is, by wrapping raw rubber tape around the threads of the bolt to form an anti-loosening structure, which also has the anti-loosening effect.

[0070] This embodiment provides a photovoltaic system including a photovoltaic module, a photovoltaic bracket 2, and the aforementioned fixing components. Therefore, the technical advantages and effects achieved by this photovoltaic system include the technical advantages and effects achieved by the aforementioned fixing components, which will not be elaborated here.

[0071] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
