[0003] In order to reduce the axial compression of C face (that is, installation position) when the module is subjected to frontal load (such as snow load), cause structural instability to lead to local plastic deformation and increase the axial tension of C face mounting hole edge when the module is subjected to back load (such as wind load) and break, the free end of the frame C face generally bends 90 degrees or so to the inside of the cavity, and the height is 4-5mm.

[0044] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. The embodiments of the present invention are not limited thereto.

[0045] Example 1

[0046] like Figure 1 As shown, an open-type steel frame for photovoltaic modules includes:

[0047] Support plate 1, which has a support surface for supporting the back surface of the photovoltaic module laminate;

[0048] Inclined plate 2, one end of which is connected to support plate 1, has an inclined surface. When the photovoltaic module is subjected to load, the frame is subjected to force on one side, reducing the bending moment and playing a supporting role.

[0049] The first side plate 3 has one end connected to the support plate 1 and is perpendicular to the support plate 1, and is used to protect the edge of the photovoltaic module laminate.

[0050] The second side plate 4 has one end connected to the inclined plate 2 and is perpendicular to the support plate 1. It is used to support the inclined plate 2 and to accommodate the nut washer and limit rotation when the bolts are tightened.

[0051] The first horizontal plate 5 has one end connected to the first side plate 3 and is parallel to the support plate 1. It is used to block the flow of sealant and prevent the sealant from overflowing from the front of the photovoltaic module during frame assembly.

[0052] The support plate 1, the first side plate 3, and the first horizontal plate 5 are arranged to form an installation groove 7 for accommodating the photovoltaic module laminate;

[0053] The second horizontal plate 6, one end of which is connected to the second side plate 4 and parallel to the support plate 1, is used to install the photovoltaic modules onto the photovoltaic bracket using bolts or clamps, and provides the main tensile and bending resistance when the frame is subjected to longitudinal bending moment, such as... Figure 3 As shown; at the same timeFigures 5-7 This is a picture of the actual product where the frame and the bracket are connected.

[0054] Support plate 1, inclined plate 2, second side plate 4, and second horizontal plate 6 form an installation cavity 8, used for installing the corner brackets at the four corners of the assembly and accommodating bolt nuts, washers, or clamps, such as... Figure 1 As shown;

[0055] The inclined plate 2 is located between the support plate 1 and the second side plate 4;

[0056] The first side plate 3 is located between the support plate 1 and the first horizontal plate 5;

[0057] The second side plate 4 is located between the inclined plate 2 and the second horizontal plate 6;

[0058] The angle between the inclined surface of the inclined plate 2 and the vertical direction is 20° to 45°.

[0059] The first side plate 3 and the second side plate 4 are located on both sides of the support plate 1, and the first side plate 3 and the second side plate 4 extend in two different directions relative to the support plate 1; the inclined plate 2 and the second side plate 4 are located on the same side of the support plate 1.

[0060] The end of the first horizontal plate 5 away from the first side plate 3 is bent into the mounting groove 7;

[0061] Among them, the bending angle of the end of the first horizontal plate 5 away from the first side plate 3 is ≥180°, and the bending length is 2~5mm;

[0062] The first horizontal plate 5 and the second horizontal plate 6 are located on both sides of the support plate 1, and the first horizontal plate 5 and the second horizontal plate 6 extend in two different directions relative to the support plate 1.

[0063] The second horizontal plate 6 has mounting holes in the middle for fixing the photovoltaic modules with bolts and washers;

[0064] The end of the second horizontal plate 6 furthest from the second side plate 4 is bent into the mounting cavity to improve the compressive instability resistance of the second horizontal plate 6.

[0065] Example 2

[0066] like Figure 2 As shown, the bent portion at the end of the first horizontal plate 5 away from the first side plate 3 forms a first bending groove 51, which is connected to the mounting groove 7. It is used to accommodate a certain amount of sealant to prevent it from overflowing onto the front of the laminate, increase the bending radius, prevent the steel strip base material from cracking due to 0T bending, and facilitate the frame mounting of the laminate. The end of the first horizontal plate 5 connected to the first side plate 3 forms an overflow groove 52, which is connected to the mounting groove 7. It is used to fill a certain thickness of sealant between the first horizontal plate 5 and the laminate to ensure adhesion and cushioning performance.

[0067] The middle part of the first horizontal plate 5 faces the mounting groove 7, forming a first groove 53 with the groove opening facing away from the mounting groove 7. This is used to reduce the amount of sealant used and to play a preliminary sealant blocking effect, making it less likely for the sealant to overflow from the front of the component.

[0068] Example 3

[0069] like Figure 4 As shown, the end of the second horizontal plate 6 away from the second side plate 4 is bent into the mounting cavity. This bend includes two bends: a first angle bend towards the inside of the cavity and a second angle bend towards the inside again. The total bending angle is the sum of the first and second angles. This is used to form a reinforced part to improve the tear resistance of the bolt edges when the module is subjected to negative pressure. The first angle is 90°, the second angle is 90 to 180°, and the total bending angle is 180 to 360°. The bend shape is an arc, which makes it less prone to instability and deformation under positive pressure after the photovoltaic module is installed, and less prone to tearing and damage under negative pressure. In addition, the cut surface of the steel strip faces downward, which makes it less prone to water accumulation and corrosion. When lifting the module, personnel will not come into contact with the cut edge, ensuring personal safety.

[0070] Example 4

[0071] like Figure 1 As shown, the steel profile for the photovoltaic module is formed by roll forming a single piece of galvanized aluminum-magnesium steel strip with a thickness of 0.6 to 1.3 mm after being slit into a specific width. The overall shape is S-shaped and consists of two parts: the upper laminate mounting groove 7 and the lower mounting cavity 8. The mounting groove 7 is a rectangular structure formed by the three sides of the frame to accommodate the photovoltaic laminate. The outer height of the groove opening is 5.0 to 6.3 mm.

[0072] The back of photovoltaic modules generally requires a visible sealant overflow line to facilitate inspection of whether the sealant fills the mounting groove. The final curing depth of the sealant is within 10mm. Therefore, the width of the frame support plate 1 is 9-14mm, and the width of the frame mounting cavity 8 is 17-23mm. When the photovoltaic module is under load, the frame bears force on one side; the inclined surface reduces bending moment and provides stronger support. The second side plate 4 of the frame is perpendicular to the second horizontal plate 6, with a height of 5-15mm. A certain number of mounting holes are formed in the middle and longitudinal sections of the second horizontal plate 6 using a stamping process. The photovoltaic module is fixed to the photovoltaic bracket through these mounting holes using bolts and U-shaped washers (20-25mm long) or round washers. Figure 3 As shown.
