Description

Technical Field

[0001] This invention belongs to the field of profile technology, specifically relating to a frame and frame fixing structure for a solar module. Background Technology

[0002] Traditional frame profile structure, such as Figure 1 and 2 As shown, the frame 1 includes two long sides 11, two short sides 12, and corner brackets 13. For installation and fixation, the long sides have a longer C-side 111, resulting in a heavier profile and a larger material consumption. Meanwhile, to mount the frame profile on the bracket, mounting holes 112 are made in the C-side 111, and fasteners passing through the mounting holes are used to mount the frame profile on the bracket.

[0003] However, because the lateral strength of composite material frames is weaker than that of aluminum alloy profiles, they are prone to cracking at the edge of the C-side mounting holes under reverse wind pressure testing, causing the photovoltaic frame to detach from the mounting bracket. Therefore, current composite material frames require a thicker C-side design, which increases the overall material usage and significantly raises the manufacturing cost of composite material frames. Summary of the Invention

[0005] To achieve the above objectives, the technical solution of the present invention is as follows:
