[0016] The present invention will be further illustrated below with reference to specific embodiments.
[0017] A composite frame for photovoltaic modules that is easy to stack and rotate, as shown in the attached Figure 1 、 2 As shown, the composite frame 1 is formed into a rectangle by two long frames 2 and two short frames 3 , and the adjacent long frames 2 and short frames 3 are connected and fixed by corner brackets.
[0018] As attached Figure 3 As shown, the profile of the long side 2 of the frame has an A surface 21, a B surface 22, and a C surface 23, which are connected in sequence to form a horizontal U-shape, wherein a cavity 24 is provided on the inner side of the corner between the B surface 22 and the C surface 23 to improve the structural strength of the corner. The cavity 24 is composed of a surface opposite to the B surface 22, a surface opposite to the C surface 23, and the B surface 22 and the C surface 23. Then, a notch 25 is formed on the inner side of the corner between the A surface 21 and the B surface 22 and the cavity 24. The long side of the laminated assembly is inserted into the notch 25 and clamped. The width W1 of the C surface 23 is greater than the width W2 of the A surface 21.
[0019] Combined with attachment Figure 1 、 4As shown in Figure 5, a rectangular anti-slip pad 4 is provided on the outer surface of the C surface 23. The thickness of the anti-slip pad 4 is 3 to 5 mm. It is a laminated structure consisting of an anti-slip layer 41 and a film layer 42. The anti-slip pad 4 is bonded to the outer surface of the C surface 23 through the film layer 42. An anti-slip pad 4 is bonded at both ends of the long side 2 of the frame. There are four anti-slip pads 4 on the composite frame 1. When bonding, a spacing L1 is left between the outer short side edge of the anti-slip pad 4 and the edge of the short side 3 of the frame, and a spacing L2 is left between the outer long side edge of the anti-slip pad 4 and the edge of the long side 2 of the frame. The spacing L1 and the spacing L2 are 30 to 50 mm. The width W3 of the anti-slip pad 4 is at least half of the width W1 of the C surface 23, and the maximum does not exceed the width W1-spacing L2.
[0020] As attached Figure 4 As shown, when the photovoltaic modules are stacked and circulated, the composite frame 1 of each module has the C side 23 of the long side 2 of the frame on the top and the A side 21 on the bottom. Then, the A side 21 of the upper composite frame 1 is pressed on the anti-slip layer 41 of the anti-slip pad 4 bonded to the C side 23 of the next composite frame 1. The widened C side and anti-slip layer increase the contact area and contact friction between the two composite frame profiles. The anti-slip pad directly prevents skewing and tipping, increases the overall mechanical load of the module, and enhances the stability of the module. The C side also provides a better fulcrum for carrying large-format modules. At the same time, the anti-slip pad can reduce scratches on the surface of the frame, and the setting of the anti-slip pad can replace the paper corner guards installed at the four corners of the frame, thereby improving the safety during stacking and circulation, improving the pressure resistance and protection effect of the frame, protecting the quality of the frame, and indirectly reducing costs.
