Abstract
Description
Technical Field
[0001] This utility model relates to the field of photovoltaic module assembly technology, and more specifically, to a frame structure and a photovoltaic module. Background Technology
[0002] With the rapid development of the solar photovoltaic industry, photovoltaic modules have been widely used in various power generation projects. Conventional photovoltaic module frames typically have an A-side, a B-side, and a C-side, with the A-side thickness covering the photovoltaic laminate. In other words, the photovoltaic module is surrounded by the frame, and the A-side thickness of the frame itself covers the photovoltaic laminate. However, this structure has significant drawbacks in actual outdoor applications. Because photovoltaic modules are exposed to the natural environment for extended periods, water and dust easily accumulate on their edges. This water and dust obstruct the module surface, directly reducing the illuminated area and severely impacting the power generation efficiency of the photovoltaic module, thus lowering the overall performance and economic benefits of the photovoltaic power generation system.
[0003] The existing frame structure has the technical problem of being unable to actively drain water, which easily leads to water stains. Utility Model Content
[0004] This invention provides a frame structure and a photovoltaic module that can achieve active drainage and prevent water stains from forming on the photovoltaic module.
[0005] The embodiments of this utility model can be implemented as follows:
[0006] An embodiment of this utility model provides a border structure, which includes:
[0007] Mounting plate, the bottom surface of which is used to contact the glass surface of the laminate;
[0008] A connecting plate, wherein the connecting plate is vertically arranged, and one edge of the connecting plate is connected to the mounting plate; and
[0009] A baffle is provided, which is arranged parallel to the mounting plate and is connected to the other side edge of the connecting plate.
[0010] The mounting plate is equipped with a drain trough.
[0011] Optionally, the sewage trough is funnel-shaped, and the sewage trough includes a first trough and a second trough that are connected to each other. The first trough has a strip-shaped structure, and the second trough has a figure-eight shape.

[0013] Optionally, the frame structure further includes a partition, which is disposed between the mounting plate and the baffle, and the partition and the mounting plate are arranged in parallel. The mounting plate, the connecting plate and the partition together form a mounting groove, which is used to install the laminate.
[0014] Optionally, the width of the partition is greater than the width of the mounting plate.
[0015] Optionally, the width of the baffle is greater than the width of the partition.
[0016] Optionally, the top surface of the mounting plate is provided with anti-slip grooves, which are arranged along the length direction of the mounting plate.
[0017] Optionally, the bottom surface of the baffle is provided with anti-slip protrusions, which are arranged along the length direction of the baffle. The anti-slip protrusions are used to cooperate with the anti-slip grooves of the adjacent frame structure when the photovoltaic modules are stacked.
[0018] Optionally, there are multiple anti-slip protrusions, which are spaced apart along the width direction of the baffle, and the number of anti-slip grooves is adapted to the number of anti-slip protrusions.

[0035] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.
[0036] With the rapid development of the solar photovoltaic industry, photovoltaic modules have been widely used in various power generation projects. Conventional photovoltaic module frames typically have an A-side, a B-side, and a C-side, with the A-side thickness covering the photovoltaic laminate. In other words, the photovoltaic module is surrounded by the frame, and the A-side thickness of the frame itself covers the photovoltaic laminate. However, this structure has significant drawbacks in actual outdoor applications. Because photovoltaic modules are exposed to the natural environment for extended periods, water and dust easily accumulate on their edges. This water and dust obstruct the module surface, directly reducing the illuminated area and severely impacting the power generation efficiency of the photovoltaic module, thus lowering the overall performance and economic benefits of the photovoltaic power generation system.
[0037] The border structure in related technologies has a technical problem: it cannot actively drain water and is prone to water stains.
[0038] Please refer to Figures 1-5 This embodiment provides a photovoltaic module 1000, including a body 200 and a frame structure 100, the frame structure 100 covering the edge of the body 200. This photovoltaic module 1000 can effectively improve the aforementioned technical problems, enabling active drainage and preventing water stains from forming on the photovoltaic module 1000.
[0039] Understandably, the body 200 mentioned in this embodiment is a laminate. The frame structure 100 covers the edge of the body 200, thereby protecting the body 200.
[0040] Specifically, there are multiple border structures 100, which are arranged sequentially along the edge of the body 200.
[0041] Please refer to Figures 1-5 This embodiment provides a frame structure 100 including a mounting plate 10, a connecting plate 30, and a baffle 40. The bottom surface of the mounting plate 10 is used to contact the glass surface of the laminate. The connecting plate 30 is vertically arranged, and one side edge of the connecting plate 30 is connected to the mounting plate 10. The baffle 40 is arranged parallel to the mounting plate 10, and the other side edge of the baffle 40 is connected to the connecting plate 30. The mounting plate 10 is provided with a drainage groove 20. The mounting plate 10 has a strip-shaped structure, and the drainage groove 20 is arranged along the width direction of the mounting plate 10 and penetrates the mounting plate 10 to ensure that rainwater and other water accumulated on the surface of the photovoltaic module 1000 can be discharged through the drainage groove 20, avoiding the formation of water stains on the surface of the photovoltaic module 1000.
[0042] In this embodiment, the sewage trough 20 is funnel-shaped and includes a first trough 21 and a second trough 22 that are connected to each other. The first trough 21 has a strip-shaped structure, and the second trough 22 has a figure-eight shape. Specifically, the second trough 22 is figure-eight shaped and has a large opening, which facilitates the collection of sewage from the surface of the photovoltaic module 1000 into the second trough 22. The accumulated water in the second trough 22 then enters the first trough 21 and is discharged from the first trough 21, thus improving the drainage and sewage discharge efficiency.
[0043] Furthermore, the drain trough 20 is grooved on the mounting plate 10 using a stamping process. The stamping process is simple, can efficiently produce while ensuring the quality of the grooving, and does not affect the mechanical strength of the mounting plate 10, ensuring that the frame structure 100 can meet the installation and usage requirements of the photovoltaic module 1000 in various environments.
[0044] Specifically, there are multiple drainage troughs 20, which are arranged sequentially along the length of the mounting plate 10. By providing multiple drainage troughs 20 on the mounting plate 10, accumulated water can be drained more quickly, avoiding excessive local water and dust accumulation that could affect the overall drainage effect. In this embodiment, there are two drainage troughs 20 on the mounting plate 10. In other embodiments, the number of drainage troughs 20 on the mounting plate 10 can be one, four, six, or even more. No specific limitation is made here.
[0045] It should be noted that the frame structure 100 also includes a partition 50, which is disposed between the mounting plate 10 and the baffle 40, and is arranged parallel to the mounting plate 10. The mounting plate 10, the connecting plate 30, and the partition 50 together form a mounting groove 60, which is used to install the laminate. The top surface of the laminate contacts the bottom surface of the mounting plate 10, and the bottom surface of the laminate contacts the top surface of the partition 50, thereby achieving assembly.
[0046] In this embodiment, the width of the partition 50 is greater than the width of the mounting plate 10, and the width of the baffle 40 is greater than the width of the partition 50.
[0047] During use, when multiple photovoltaic modules 1000 are stacked, slippage may occur between them, potentially damaging them. To address this issue, the mounting plate 10 of the frame structure 100 provided in this embodiment has an anti-slip groove 80 on its top surface, extending along the length of the mounting plate 10. The bottom surface of the baffle 40 has an anti-slip protrusion 70, extending along the length of the baffle 40. The anti-slip groove 80 engages with the anti-slip protrusion 70 of adjacent frame structures 100 when the photovoltaic modules 1000 are stacked. The frame structures 100 of two adjacent photovoltaic modules 1000 are interlocked through the engagement of the anti-slip protrusion 70 and the anti-slip groove 80, thus preventing slippage when the photovoltaic modules 1000 are stacked and ensuring their safety.
[0048] In other embodiments, anti-slip protrusions 70 may be provided on the top surface of the mounting plate 10, with the anti-slip protrusions 70 arranged along the length direction of the mounting plate 10. Anti-slip grooves 80 may be provided on the bottom surface of the baffle 40, with the anti-slip grooves 80 arranged along the length direction of the baffle 40. The anti-slip grooves 80 are used to cooperate with the anti-slip protrusions 70 of adjacent frame structures 100 when the photovoltaic modules 1000 are stacked. The frame structures 100 of two adjacent photovoltaic modules 1000 are engaged through the cooperation between the anti-slip protrusions 70 and the anti-slip grooves 80, thereby preventing slippage when the photovoltaic modules 1000 are stacked together and ensuring the safety of the photovoltaic modules 1000.
[0049] Furthermore, there are multiple anti-slip protrusions 70, which are spaced apart along the width direction of the baffle 40, and the number of anti-slip grooves 80 is matched with the number of anti-slip protrusions 70.
[0050] In this embodiment, there are two anti-slip protrusions 70. In other embodiments, the number of anti-slip protrusions 70 may be increased or decreased, and no specific limitation is made here.
[0051] In this embodiment, the frame structure 100 can be made of aluminum alloy or composite material, etc., and no specific limitation is made here.
[0052] The frame structure 100 and photovoltaic module 1000 provided in this embodiment have at least the following advantages:
[0053] In this embodiment, the drainage groove 20 of the frame structure 100 is grooved on the mounting plate 10 by a stamping process. The stamping process is simple, can efficiently produce while ensuring the quality of the grooving, and does not affect the mechanical strength of the mounting plate 10, ensuring that the frame structure 100 can meet the installation and usage requirements of the photovoltaic module 1000 in various environments.
[0054] The sewage trough 20 provided in this embodiment includes a first trough 21 and a second trough 22 that are connected to each other. The first trough 21 has a strip-shaped structure, and the second trough 22 has a figure-eight-shaped structure. The opening of the second trough 22 is larger, which facilitates the collection of sewage from the surface of the photovoltaic module 1000 into the second trough 22. The water collected in the second trough 22 then enters the first trough 21 and is discharged from the first trough 21, thereby improving the drainage and sewage discharge efficiency.

The frame structure 100 includes a mounting plate 10, a connecting plate 30, and a baffle 40. The bottom surface of the mounting plate 10 is used to contact the glass surface of the laminate.

The baffle 40 is arranged parallel to the mounting plate 10, and the other side edge of the baffle 40 is connected to the connecting plate 30. The mounting plate 10 is provided with a drainage groove 20. In use, the mounting plate 10 has a drainage groove 20, and the bottom surface of the mounting plate 10 can contact the glass surface of the laminate. The drainage groove 20 can actively drain water accumulated on the surface of the laminate, preventing rainwater from accumulating on the surface of the laminate and forming water stains.
