A photovoltaic module frame profile

Abstract

This utility model relates to the field of photovoltaic module technology, and in particular to a photovoltaic module frame profile, including a profile body. The profile body has a cavity and a mounting groove. The cavity is surrounded by two vertical plates, a top plate connected to the top of the two vertical plates, and a bottom plate connected to the bottom of the two vertical plates. The middle of each of the two vertical plates is recessed into the cavity to form a groove. The mounting groove is located at the top of the profile body. The starting end of the profile body is bent into a large U-shape to wrap around a small U-shape. The recessed structure of the two vertical plates surrounding the cavity, forming grooves, creates a structure similar to a reinforcing rib, thereby improving the impact resistance of the vertical plates on both sides of the cavity and thus increasing the strength of the frame profile. The double-bending structure, where the starting end of the profile body is bent into a large U-shape to wrap around the small U-shape, provides better torsional resistance and higher stability than a single bend, and eliminates the need for welding, riveting, or bonding.

Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module technology, and in particular to a photovoltaic module frame profile. Background Technology

[0002] The frame of a photovoltaic module is an important component used to fix the photovoltaic module. It provides rigid support for the photovoltaic glass, cells and backsheet, resists the impact of external forces such as wind, sand, hail, and falling objects, prevents the module from breaking or deforming, and ensures that the module maintains structural stability in harsh weather. In addition, the frame indirectly extends the life of the module and reduces maintenance costs by protecting the internal materials from physical damage.

[0003] As disclosed in Chinese Patent Publication No. CN114844455A, the vertical plate of the cavity of the existing frame profile is a flat plate. This structure makes the impact resistance on both sides of the cavity weak, which makes the overall strength of the frame low. Moreover, the starting head of the profile is obtained by wrapping the small upper vertical wall with a U-shaped part (single bend). Utility Model Content

[0004] This utility model solves the problems in related technologies and proposes a photovoltaic module frame profile. The middle of the two vertical plates surrounding the cavity is recessed into the cavity to form a groove. This recessed structure forms a structure similar to a reinforcing rib, thereby improving the impact resistance of the vertical plates on both sides of the cavity and thus improving the strength of the frame profile. The starting end of the profile body is bent into a large U-shaped part to wrap a small U-shaped part. This double-bending structure has higher stability than a single-bending structure.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a photovoltaic module frame profile, including a profile body, the profile body is provided with a cavity and a mounting groove, the cavity is surrounded by two vertical plates, a top plate connected to the top of the two vertical plates and a bottom plate connected to the bottom of the two vertical plates, the middle part of the two vertical plates is recessed into the cavity to form a groove, the mounting groove is located at the top of the profile body, and the starting end of the profile body is bent into a large U-shaped part to wrap a small U-shaped part.

[0006] As a preferred embodiment, the vertical plate includes a first vertical plate and a second vertical plate, wherein the first vertical plate is bent to one side to form a top plate.

[0007] As a preferred embodiment, the top plate and the second vertical plate are bent upwards into an L-shaped structure to form an installation groove.

[0008] As a preferred embodiment, both the first vertical plate and the second vertical plate are bent to the other side to form a first bottom plate and a second bottom plate, respectively, with the second bottom plate located below the first bottom plate.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: the two vertical plates surrounding the cavity are recessed inward to form grooves, which form a structure similar to a reinforcing rib, thereby improving the impact resistance of the vertical plates on both sides of the cavity and thus improving the strength of the frame profile; the starting end of the profile body is bent into a large U-shaped part to wrap the small U-shaped part. This double-bending structure has better torsional resistance and higher stability than a single bending, and does not require additional welding, riveting or bonding. Attached Figure Description
