Description

Technical Field

[0001] The utility model relates to the technical field of frame profiles, in particular to a frame profile for a solar cell. Background Art

[0002] A profile refers to a solid straight bar formed by plastic processing of metal, having a certain cross-sectional shape and size. There are a wide variety of profile varieties and specifications, and they are widely used, occupying a very important position in rolling production; profiles are objects with a certain geometric shape made of iron, steel, or materials with certain strength and toughness through processes such as rolling, extrusion, and casting. Such materials have certain appearance dimensions, a certain cross-sectional shape, and certain mechanical and physical properties. Profiles can be used alone or further processed into other manufactured products, and are commonly used in building structures and manufacturing installations. Mechanical engineers can select parameters such as the specific shape, material, heat treatment state, and mechanical properties of the profile according to design requirements, then divide the profile according to specific dimensional shape requirements, and then further process or heat treat it to meet the design accuracy requirements. The material, specifications, dimensions, etc. of the profile can refer to the corresponding national standards.

[0003] For most of the existing frame profiles for solar cells, due to the requirement of light weight, multiple through holes are provided on the aluminum profile to reduce the weight, and the thickness of the edge is the same as that of the middle connecting part. Therefore, when the edge is squeezed, the middle connecting rod is bent, resulting in the deformation of the entire profile; there are also some frame profiles for solar cells. To ensure strength, their overall thickness is relatively thick, resulting in excessive strength, thus wasting materials and increasing costs. Summary of the Utility Model
