AI Technical Summary

Technical Problem

Existing photovoltaic frames suffer from problems such as difficult connection, insufficient waterproofing, high production costs, and low strength in lightweight designs, making them unsuitable for large-scale photovoltaic systems.

Method used

Thin plates are used as the main profile material. The design incorporates a double-layer structure with an upper support edge and an inner reinforcing edge, combined with corner reinforcements to form a C-shaped frame. The frame is then connected by welding and snap-fit ​​methods to increase strength and support capacity.

Benefits of technology

It achieves lightweight photovoltaic frames, improves connection strength and protection, reduces production costs, and is suitable for large-scale photovoltaic systems.

Abstract

This invention discloses a lightweight photovoltaic frame and its assembly method, relating to the field of photovoltaic frame technology. The invention includes four profiles, which are welded together to form a rectangular frame body. Corner reinforcements are provided at each of the four corners of the frame body. Each profile includes a bottom edge, an outer edge on one side of the bottom edge, and a crease on the inner side of the middle of the outer edge. The crease has a triangular cross-section with the pointed end facing outwards, and the crease angle is 90 degrees, dividing the outer edge into a side section and a top section. An upper support edge is provided on the other side of the bottom edge via a bending section. This invention uses a thin plate as the main material of the profile, achieving lightweight characteristics. The double-layer structure formed by the upper support edge and inner reinforcing edge improves the strength and high support capacity of the bottom of the profile. The single-layer thin plate used for the side and top sections of the profile provides good lightweight performance. Furthermore, using thin plates of the same thickness to form the main body of the profile facilitates molding.
