AI Technical Summary

Technical Problem

Photovoltaic modules may move relatively during transportation, resulting in unstable installation. The prior art uses corner guard fixing, but increases transportation costs. As the component size increases, it is difficult to effectively fix the component frames using the chunk fixing method.

Method used

A component frame is designed, including a top plate, a bottom plate and a plurality of toothed structures arranged in a specific direction to enhance the connection stability with the laminate and to cover the first toothed structure by projection of the second toothed structure to increase friction.

Benefits of technology

Improves the efficiency and installation reliability of stacked photovoltaic modules, reduces the use of corner guards, reduces transportation costs, and is compatible with chunks of different specifications.

Abstract

The invention provides a module frame and a photovoltaic module. The assembly frame is used for being connected with a laminated piece and comprises a top plate. The bottom plate is arranged opposite to the top plate in the first direction; the first tooth-shaped structures are sequentially arranged on the top surface of the top plate in the second direction, each first tooth-shaped structure comprises a first tooth surface and a second tooth surface, the first tooth surface is closer to the side plate than the second tooth surface in the second direction, the second tooth surface is in contact with the first tooth surface of the adjacent first tooth-shaped structure, the second tooth surface comprises an upper tooth surface and a lower tooth surface, and the upper tooth surface is in contact with the lower tooth surface. One end of the upper tooth surface is contacted with the first tooth surface, the other end is contacted with one end of the lower tooth surface, and the other end of the lower tooth surface is contacted with the first tooth surface of the adjacent first tooth-shaped structure. According to the module frame, the efficiency of stacking the photovoltaic modules can be improved, and meanwhile, the module frame has a relatively high error-tolerant rate; in addition, the first tooth-shaped structure can be compatible with pressing blocks of different specifications, and meanwhile the effect of improving the installation reliability is achieved.
