Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module technology, and in particular to a photovoltaic module frame. Background Technology

[0002] As the core component of a photovoltaic (PV) power generation system, the frame of a PV module plays a crucial role in supporting, fixing, and protecting the PV panels in practical applications. Currently, existing PV module frames suffer from several problems: Firstly, traditional frame structures are relatively simple, relying solely on a single frame structure for support. When faced with harsh natural environments such as strong winds and blizzards, the frame is prone to deformation or even damage, leading to loosening of the PV panels and affecting their normal operation. In severe cases, it can even cause the PV panels to break, reducing the power generation efficiency and lifespan of the PV power station. Secondly, existing frames lack effective internal reinforcement designs, failing to significantly improve the overall strength and stability of the frame without substantially increasing material costs and weight, making it difficult to meet the growing demands for larger and more reliable PV modules.

[0003] Therefore, there is an urgent need to design a photovoltaic module frame structure that can effectively improve stability and robustness. Utility Model Content

[0004] To overcome existing problems, this application provides a photovoltaic module frame. By setting reinforcing ribs inside the frame, especially a reinforcing rib structure including horizontal and vertical ribs, the stability and robustness of the frame itself are effectively improved, thereby enhancing the overall structural stability of the photovoltaic module and enabling it to better adapt to various complex environments, ensuring the reliable operation of the photovoltaic module.

[0005] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0006] A photovoltaic module frame includes a frame, which serves as the main supporting structure of the frame. The frame adopts a rectangular design, surrounding and fixing the photovoltaic panel. While ensuring lightweight construction, it can withstand the weight of the photovoltaic panel itself and external wind and snow loads. Manufactured using an extrusion molding process, it boasts high dimensional accuracy and surface quality. The straightness error of each side of the molded frame is controlled within a minimal range, ensuring the flatness and sealing of the photovoltaic panel during installation. A buckle is located at the top of the frame. The frame contains internal reinforcing ribs, including transverse and longitudinal ribs. The cross-sectional dimensions of the transverse and longitudinal ribs are identical, but the spacing between adjacent transverse ribs differs from the spacing between adjacent longitudinal ribs. The transverse ribs are arranged transversely along the frame, and the longitudinal ribs are arranged longitudinally along the frame. The transverse and longitudinal ribs are interwoven to form a grid-like reinforcing structure. The transverse ribs are evenly distributed along the transverse direction of the frame, and the longitudinal ribs are arranged along the longitudinal direction of the frame, and are fixed to the frame by welding. For the reinforced frame of large photovoltaic modules, a double-layer staggered reinforcing rib structure is adopted. The inner and outer ribs work together to form a three-dimensional support network, which further enhances the frame's resistance to torsion and bending.

[0007] Preferably, a support plate is provided on one side of the frame to support the photovoltaic panel. The support plate is made of aluminum alloy sheet, which is cut and bent to fit tightly against the inside of the frame. Its shape is adapted to the edge contour of the frame and the photovoltaic panel to ensure full contact with the photovoltaic panel and provide uniform support. The support plate is fixed to the frame with rivets at reasonable intervals, ensuring connection strength while avoiding aesthetics and increased processing costs due to overly dense connection points. The frame is the main frame structure, and the frame is made of aluminum alloy through an extrusion molding process.

[0008] Preferably, the buckle has an irregular structure, a groove is provided on the lower surface of the buckle, the buckle is made of high-strength engineering plastic, and it is connected to external components through an integral molding structure. The buckle is elastic and can deform under external force.

[0009] Preferably, the frame and the internal space of the buckle have an irregular structure, with a size that is smaller on the outside and larger on the inside. When the photovoltaic panel is installed in the buckle and inside the frame, the special structure can generate a large compressive force on the photovoltaic panel.

[0010] The advantages of the embodiments of this application are:

[0011] 1. The interlacing horizontal and vertical ribs inside the frame form a grid-like reinforcement structure, which can support and reinforce the frame from multiple directions. The horizontal ribs can effectively resist the deformation caused by the horizontal force on the photovoltaic panel, while the vertical ribs can cope with the longitudinal external force. The two work together to greatly enhance the stability and robustness of the frame, so that the photovoltaic module can still maintain the structural integrity when subjected to external forces such as strong winds and blizzards, reducing the risk of damage to the photovoltaic panel and ensuring the normal operation of the photovoltaic module.

[0012] 2. The grid-like reinforcing rib structure can evenly distribute the external force on the photovoltaic module to the entire frame, avoiding excessive local stress that could damage the frame. This uniform force distribution not only improves the load-bearing capacity of the frame but also extends the service life of the photovoltaic module and reduces maintenance costs.

[0019] This application provides a photovoltaic module frame that addresses the problems in the prior art. The frame features an interlocking grid-like reinforcing structure formed by horizontal and vertical ribs, providing support and reinforcement from multiple directions. The horizontal ribs effectively resist deformation caused by lateral forces on the photovoltaic panel, while the vertical ribs withstand longitudinal external forces. This synergistic action significantly enhances the frame's stability and robustness, ensuring the photovoltaic module maintains structural integrity even under impacts from strong winds, blizzards, and other external forces, reducing the risk of damage to the photovoltaic panel and guaranteeing its normal operation. The grid-like reinforcing structure evenly distributes the external forces on the photovoltaic module across the entire frame, preventing excessive localized stress that could damage the frame. This uniform force distribution not only improves the frame's load-bearing capacity but also extends the photovoltaic module's lifespan and reduces maintenance costs.

[0020] The technical solution in this application is to solve the above problems, and the overall approach is as follows:

[0021] Example

[0022] This embodiment provides a specific structure for a photovoltaic module frame, such as... Figure 1-3 As shown, the system includes a frame 3, which serves as the main supporting structure for the frame. The frame 3 employs a rectangular frame design, surrounding and fixing the photovoltaic panel. While ensuring lightweight construction, it can withstand the weight of the photovoltaic panel itself and external wind and snow loads. Manufactured using an extrusion molding process, it boasts high dimensional accuracy and surface quality. The straightness error of each side of the frame 3 after molding is controlled within a minimal range, ensuring the flatness and sealing of the photovoltaic panel during installation. A buckle 4 is located at the top of the frame 3. The frame 3 contains reinforcing ribs 2, including transverse ribs 6 and longitudinal ribs 7. The cross-sectional dimensions of the transverse ribs 6 and longitudinal ribs 7 are identical, but the spacing between adjacent transverse ribs 6 differs from the spacing between adjacent longitudinal ribs 7. The transverse ribs 6 are arranged transversely along the frame 3, and the longitudinal ribs 7 are arranged longitudinally along the frame 3. The transverse ribs 6 and longitudinal ribs 7 are interwoven to form a grid-like reinforcing structure. The reinforcing rib 2 is composed of transverse ribs 6 and longitudinal ribs 7, which are interwoven to form a grid-like structure. The transverse ribs 6 are evenly distributed along the transverse direction of the frame 3, and the longitudinal ribs 7 are arranged along the longitudinal direction of the frame 3, and are fixed to the frame 3 by welding. For the reinforced frame of large photovoltaic modules, a double-layer staggered reinforcing rib structure is adopted. The inner and outer ribs work together to form a three-dimensional support network, which further enhances the frame's resistance to torsion and bending.

[0023] A support plate 1 is provided on one side of the frame 3 to support the photovoltaic panel. The support plate 1 is made of aluminum alloy sheet, which is cut and bent and then tightly fitted to the inside of the frame 3. Its shape is adapted to the contours of the frame 3 and the edge of the photovoltaic panel to ensure full contact with the photovoltaic panel and provide uniform support. The support plate 1 is fixed to the frame 3 with rivets at reasonable intervals, which ensures the connection strength while avoiding aesthetics and increased processing costs due to overly dense connection points. The frame 3 is the main frame structure and is made of aluminum alloy through an extrusion molding process.

[0024] The buckle 4 has an irregular structure, and a groove 5 is provided on the lower surface of the buckle 4. The buckle 4 is made of high-strength engineering plastic and is connected to external parts through an integral molding structure. The buckle 4 is elastic and can deform under external force.

[0025] The internal space of frame 3 and buckle 4 is an irregular structure, with a smaller outer shape and a larger inner shape. When the photovoltaic panel is installed in buckle 4 and inside frame 3, the special structure can exert a large compressive force on the photovoltaic panel.

[0026] By adopting the above technical solution:

[0027] The assembled frame is placed around the photovoltaic panel, and the photovoltaic panel is placed on the support plate 1. The position between the photovoltaic panel and the frame is accurate. The photovoltaic module is connected and fixed to the photovoltaic bracket or other installation parts by the buckle 4 to complete the overall assembly of the photovoltaic module.

[0028] The reinforcing rib 2 includes transverse ribs 6 and longitudinal ribs 7. The cross-sectional dimensions of the transverse ribs 6 and longitudinal ribs 7 are identical. The spacing between adjacent transverse ribs 6 is different from the spacing between adjacent longitudinal ribs 7. The transverse ribs 6 are arranged transversely along the frame 3, and the longitudinal ribs 7 are arranged longitudinally along the frame 3. The transverse ribs 6 and longitudinal ribs 7 are interwoven to form a grid-like reinforcing structure. The reinforcing rib 2 is composed of transverse ribs 6 and longitudinal ribs 7, which are interwoven to form a grid-like structure. The transverse ribs 6 are evenly distributed along the transverse direction of the frame 3, and the longitudinal ribs 7 are arranged along the longitudinal direction of the frame 3, and are fixed to the frame 3 by welding. For the reinforced frame of large photovoltaic modules, a double-layered staggered reinforcing rib 2 structure is adopted. The inner and outer layers of ribs cooperate to form a three-dimensional support network, further enhancing the frame's resistance to torsion and bending.

[0029] After the frame 3 with welded reinforcing ribs 2 is fixed to the support plate 1, it is then embedded around the photovoltaic panel. Testing showed that when the frame was subjected to a wind pressure of 1200 Pa (simulating a level 10 wind), the deformation of the frame 3 was less than 0.5 mm, and there was no loosening at the connection between the photovoltaic panel and the frame. Under a wind pressure of 300 kg / m², the frame 3 also showed good stability. 2 Under snow load, the reinforcing rib 2 effectively dispersed the pressure, and the frame 3 did not exhibit plastic deformation.

[0030] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
