AI Technical Summary
Technical Problem
The existing cantilever structure design of photovoltaic frames makes molding difficult, and the glue overflow groove is easily scraped open to form lumps, leading to assembly failure.
Method used
The photovoltaic frame is made of weldless aluminum alloy and is formed by hot extrusion of aluminum alloy. The design includes an open cavity and an overflow groove support wall to form a receiving groove, which simplifies the mold structure and improves the structural strength.
Benefits of technology
It reduces mold costs, simplifies the molding process, improves the structural strength of the photovoltaic frame, prevents sealant overflow, and ensures assembly stability.

Abstract
A weldless aluminum alloy photovoltaic frame, its mounting structure, and a photovoltaic module are disclosed. The photovoltaic frame includes: a plurality of walls surrounding and defining a cavity with an open cross-section; a vertical wall erected midway along one half of the wall on one side of the open opening; an overflow groove support wall erected midway along the other half of the wall on the other side of the open opening; and an overflow groove connected to the overflow groove support wall and configured to open towards the vertical wall. A receiving groove for inserting photovoltaic panels is surrounded and defined by the vertical wall, the overflow groove, the overflow groove support wall, a portion of the half of the wall on one side of the open opening extending towards the open opening relative to the vertical wall, and another portion of the other half of the wall on the other side of the open opening extending towards the open opening relative to the overflow groove support wall. Thus, the mold used for the non-enclosed mechanism can be a planar mold, resulting in low cost and easy molding.
