Furthermore, existing protective measures mostly involve using integral welded protective components for the frame, which not only increases the weight of the module but also requires complete replacement after damage, resulting in high maintenance costs. To address these issues, those skilled in the art have developed a photovoltaic module frame structure with protective capabilities to solve the problems mentioned in the background section.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Please see Figures 1-6 As shown, this utility model provides a technical solution: a photovoltaic module frame structure with protective effect, including a lower frame 1, a sealing component 2 for sealing and protection on the upper end surface of the lower frame 1, an upper frame 3 on the upper end surface of the sealing component 2, a photovoltaic panel 4 installed between the lower frame 1 and the sealing component 2, a plurality of protective components 5 for protecting the corners of the upper frame 1 and the lower frame 3 installed on the side wall of the upper frame 3, and a plurality of fixing components 6 for fixing the upper frame 3 and the lower frame 1 installed on the side wall of the upper frame 3.

[0026] The photovoltaic module frame structure utilizes corner protectors 502 in the protective component 5 to protect the corners of the upper frame 3 and lower frame 1. By physically wrapping the edges of the upper frame 3 and lower frame 1, it effectively disperses impact stress during transportation and installation, reduces the risk of deformation of the corners of the upper frame 3 and lower frame 1, and effectively prevents wear and tear from stacked photovoltaic modules. The corner protectors 502 are fixed to the side wall of the upper frame 3 via clips 505 and slots 508, allowing for modular design that enables quick assembly and disassembly, making operation convenient and avoiding delays associated with traditional welding protection. During maintenance, it allows for targeted replacement of damaged modules, reducing maintenance costs. Simultaneously, the sealing gasket 201 in the photovoltaic module frame structure, through its circumferential wrapping design, forms a continuous and sealed protective barrier at the edge of the photovoltaic panel 4. The sealing gasket 201 is tightly fitted to the junction area of ​​the laminated structure of the photovoltaic panel 4, lower frame 1, and upper frame 3, effectively blocking the longitudinal penetration path of rainwater, condensation, and other liquid moisture, maintaining long-term sealing stability.

[0027] As one implementation method in this embodiment, please refer to Figures 1-3 As shown, the sealing component 2 includes a sealing gasket 201, which is disposed between the lower frame 1 and the upper frame 3, and the sealing gasket 201 is made of silicone.

[0028] In the frame structure of this photovoltaic module, the sealing gasket 201 forms a continuous and sealed protective barrier at the edge of the photovoltaic panel 4 through a full circumferential wrapping design. The sealing gasket 201 is tightly attached to the junction area of ​​the laminated structure of the photovoltaic panel 4, the lower frame 1 and the upper frame 3, effectively blocking the longitudinal penetration path of liquid water such as rainwater and condensation, and maintaining long-term sealing stability.

[0029] As one implementation method in this embodiment, please refer to Figures 4-5 As shown, the protective component 5 includes a slot 501, which is located on the side wall of the lower frame 1 near the edge, and a corner guard 502 slides inside the slot 501.

[0030] In the frame structure of this photovoltaic module, the corner guards 502 in the protective component 5 protect the corners of the upper frame 1 and the lower frame 3. By physically wrapping the edges of the upper frame 1 and the lower frame 3, the impact stress during transportation and installation can be effectively dispersed, reducing the risk of deformation of the corners of the upper frame 1 and the lower frame 3, and effectively avoiding wear and tear from the stacking of photovoltaic modules.

[0031] As one implementation method in this embodiment, please refer to Figures 4-5As shown, a sliding cavity 503 is provided inside the corner guard plate 502. A movable plate 504 is slidably connected to the inner wall of the sliding cavity 503. A locking block 505 is fixedly connected to the upper end face of the movable plate 504. A spring 506 is fixedly connected between the lower end face of the movable plate 504 and the inner wall of the sliding cavity 503. A toggle block 507 is fixedly connected to the side wall of the movable plate 504. The toggle block 507 is slidably connected inside the corner guard plate 502. A slot 508 is provided on the upper inner wall of the slot 501. The locking block 505 passes through the corner guard plate 502 and engages with the slot 508.

[0032] When the corner protector 502 needs to be removed, the user presses down the actuating block 507, causing the moving plate 504 located in the sliding cavity 503 to slide downwards. The spring 506 retracts, and the locking block 505 moves downwards and out of the slot 508, allowing the corner protector 502 to be pulled out of the slot 501. When the corner protector 502 needs to be installed, the user presses down the actuating block 507, causing the locking block 505 to temporarily retract into the sliding cavity 503. Then, the corner protector 502 is inserted into the slot 501. When the 05 is aligned with the slot 508, the user releases the toggle block 507, the spring 506 resets, and the locking block 505 automatically moves into the slot 508, thereby limiting and fixing the corner protector 502. The corner protector 502 is fixed to the side wall of the upper frame 3 through the locking block 505 and the slot 508. The modular design of the corner protector 502 supports quick disassembly and assembly, is easy to operate, avoids the delay in construction period of traditional welding protection, and supports targeted replacement of damaged modules during operation and maintenance, reducing maintenance costs.

[0033] As one implementation method in this embodiment, please refer to Figure 6 As shown, the fixing component 6 includes a fixing block 601, which is fixedly connected to the side wall of the upper frame 3. A bolt 602 is slidably sleeved at the center of the fixing block 601. A fixing cylinder 603 is fixedly connected to the side wall of the lower frame 1. The fixing cylinder 603 is directly opposite the fixing block 601. An internal threaded hole 604 is opened at the center of the upper end of the fixing cylinder 603. The front end of the bolt 602 is threadedly connected to the internal threaded hole 604.

[0034] Users can complete the splicing and fixing between the upper frame 3 and the lower frame 1 by passing the bolt 602 through the fixing block 601 and then threading the bolt 602 into the internal threaded hole 604 on the fixing cylinder 603. This allows users to disassemble the upper frame 3 and the lower frame 1, making it easier for users to replace the sealing gasket 201 of the sealing component 2 and ensuring the sealing performance of the photovoltaic module frame structure.

[0035] As one implementation method in this embodiment, please refer to Figures 1-3 As shown, the corner protector 502 has a protective pad 7 on the side wall away from the upper frame 3. The protective pad 7 is made of soft rubber. The sealing pad 201 is attached to the inner wall of the upper frame 3. The sealing pad 201 is made of silicone.

[0036] The protective pad 7 can significantly improve the overall protective performance of the corner protector 502. The soft rubber protective pad 7 effectively absorbs the impact energy during transportation bumps or installation collisions through elastic cushioning. In addition, the high coefficient of friction of the protective pad 7 can prevent sliding and displacement when components are stacked. The silicone has excellent weather resistance, impermeability and electrical insulation, and can effectively block moisture penetration.

[0037] Working Principle: In this photovoltaic module frame structure, the sealing gasket 201, through its full-circumferential wrapping design, forms a continuous and sealed protective barrier at the edge of the photovoltaic panel 4. The sealing gasket 201 is tightly attached to the interface area of ​​the laminated structure of the photovoltaic panel 4, the lower frame 1, and the upper frame 3, effectively blocking the longitudinal penetration path of rainwater, condensation, and other liquid moisture, maintaining long-term sealing stability. Secondly, in this photovoltaic module frame structure, the corner protectors 502 in the protective component 5 protect the corners of the upper frame 1 and the lower frame 3. By physically wrapping the edges of the upper frame 1 and the lower frame 3, the impact stress during transportation and installation can be effectively dispersed, reducing the risk of deformation of the corners of the upper frame 1 and the lower frame 3, and effectively avoiding wear and tear from the stacking of photovoltaic modules. When it is necessary to remove the corner protector 502, the user presses down the actuating block 507, and the moving plate 50 in the sliding cavity 503... 4. Slide downwards, spring 506 retracts, and locking block 505 moves downwards and moves out of slot 508, allowing corner protector 502 to be pulled out of slot 501. When corner protector 502 needs to be installed, press down on toggle block 507, causing locking block 505 to temporarily retract into sliding cavity 503. Then insert corner protector 502 into slot 501. When locking block 505 is aligned with slot 508, the user releases toggle block 507, spring 506 returns to its original position, and locking block 505 automatically moves into slot 508, thus limiting and fixing corner protector 502. Corner protector 502 is fixed to the side wall of upper frame 3 by locking block 505 and slot 508. The modular design of corner protector 502 supports quick disassembly and assembly, is easy to operate, avoids the delays of traditional welding protection, and supports targeted replacement of damaged modules during maintenance, reducing maintenance costs.
