[0029] Example 1

[0030] Reference Figures 1 to 3 This utility model provides a photovoltaic module frame. The frame has a cavity 110 extending along the length direction of the frame. The cavity 110 is divided into segments along the length direction and multiple fillers 2 are arranged. The frame has a connecting part 13 extending to one side of the frame. For the installation of the photovoltaic module, the connecting part 13 is divided into segments along the length direction and multiple sets of mounting holes are provided. The fillers 2 are arranged at the corresponding positions of the mounting holes of the frame.

[0031] This invention enhances the strength and load-bearing capacity of the frame by arranging filler 2 within the cavity 110 of the frame. Furthermore, by segmenting multiple filler 2 within the cavity 110 along its length, material consumption and costs are reduced. Additionally, since the frame has multiple sets of mounting holes, stress concentration can easily occur at these locations after the photovoltaic module is installed. Therefore, arranging filler 2 within the cavity 110 corresponding to each set of mounting holes optimizes the load distribution of the load-bearing portion 11 and increases the frame's load-bearing capacity.

[0032] Furthermore, in order not to affect the load-bearing capacity of the load-bearing part, the filler 2 is fixed in the cavity 110 by stamping anchor points 3.

[0033] In some embodiments, the frame is made of aluminum alloy because aluminum alloy has advantages such as strong corrosion resistance, low density, high strength, good heat dissipation, easy processing, and good recyclability. Furthermore, the filler 2 is made of steel, aluminum alloy, or polymer, etc.

[0034] In some embodiments, the filler 2 includes an insulating cover at least on the surface of the filler 2 that contacts the cavity 110. When the filler is a metal part, the insulating cover on the surface of the filler can prevent contact corrosion caused by direct contact between the filler and the metal frame.

[0035] In some embodiments, the insulating cover is a polymer coating, ceramic coating, glass coating, or rubber coating attached to the outer surface of the filler 2. For example, a molecular bond is formed between the insulating cover and the filler 2.

[0036] In some embodiments, the insulating cover is an insulating sleeve that wraps around the filler 2. For example, the insulating sleeve can be a rubber strip or a plastic sleeve.

[0037] Furthermore, a plurality of protrusions 111 are provided at the top and / or bottom of the cavity 110, and the plurality of protrusions 111 contact the filling portion 2.

[0040] Preferably, the cross-section of the filler 2 is generally "C" shaped or rectangular.

[0041] Furthermore, the outer corners of the filler 2 are rounded to prevent the filler 2 from scratching the cavity 110 during assembly.

[0042] In some embodiments, the frame includes a mounting portion 12 for encapsulating the laminate and a support portion 11 connected below the mounting portion 12. The support portion 11 is used to support the weight of the laminate and is provided with the cavity 110 described above.

[0043] In some embodiments, the inner side of the mounting part 12 has a mounting groove 120 extending along the length direction and an overflow groove 121 communicating with the mounting groove 120. The edge of the laminate is encapsulated in the mounting groove 120 and is fixed to the groove wall of the mounting groove 120 by adhesive. When framing, the adhesive is squeezed by the laminate and overflows into the overflow groove, thereby forming a uniform adhesive layer between the frame and the laminate.
