Technical Field

[0001] The utility model relates to the technical field of photovoltaic modules, and particularly to a frame for a photovoltaic panel. Background Art

[0002] Before a photovoltaic panel is put into use, it needs to be assembled with a frame for support and fixation to facilitate on-site installation.

[0003] For example, in a Chinese invention patent with the authorization announcement number CN117914243A, a frame structure is disclosed, including a frame. The frame includes a cavity, and a boss portion is provided on the frame. The boss portion includes a concave surface recessed outside the cavity and a convex surface protruding inside the cavity. A disassembly hole is provided on the boss portion, which penetrates through the concave surface and the convex surface for a disassembly tool to penetrate into the cavity. The above technical solution can enable a disassembly tool to penetrate into the cavity, and deform the convex surface by squeezing the convex surface towards the concave surface through the disassembly tool, so that the boss portion becomes flat, that is, the limit of the boss portion fails, facilitating disassembly.

[0004] Although the above invention patent has the beneficial effects of being easy to disassemble and being able to reuse parts, the production is difficult and the efficiency is low. Therefore, the photovoltaic panel frame of the present invention is urgently needed in this field to solve the problems existing in the prior art. Content of the Utility Model

The first frame side and the second frame side have the same cross-sectional shape.

[0007] Both the first frame side and the second frame side are formed by bending a piece of plate, and include a support frame body with a rectangular cross-section, and an installation groove body with a rectangular cross-section arranged above the support frame body. An installation opening is provided at one end of the installation groove body.

[0008] Both ends of the plate are located above the installation opening. After one end of the plate is bent 180°, the other end of the plate is wrapped to form a wrapped edge area, having a stable photovoltaic panel support structure. The edge of the photovoltaic panel is clamped into the installation groove body, and the photovoltaic panel is effectively supported vertically and laterally limited.

[0009] As a preferred technical solution, the corner bracket is L-shaped and includes two clamping columns that are fixedly connected at 90°. The two clamping columns are respectively embedded into the support frame bodies inside the first frame side and the second frame side.

[0010] As a preferred technical solution, on the side of the installation groove body away from the installation opening, the plate has two regions that are closely attached to each other, and the two regions are fixedly connected. At this time, both the end near the installation opening and the end away from the installation opening of the installation groove body have rigid vertical support structures.

[0011] As a preferred technical solution, the two regions of the plate that are closely attached to each other are connected by laser welding, and the welding points are located on the surface of the plate inside the installation groove body.

[0012] As a preferred technical solution, clamping structures that are engaged with each other are respectively arranged on the side wall of the support frame body and the side wall of the corner code.

[0013] As a preferred technical solution, the clamping structure includes a buckle and a clamping tooth groove. A buckle that bends towards the inside of the support frame body is provided on the side wall of the support frame body, and a clamping tooth groove is arranged on the side wall of the clamping column. The buckle is inserted into the groove of the clamping tooth groove, so that the corner code cannot be pulled out of the support frame body.

[0014] As a preferred technical solution, the thickness of the clamping column is equal to the height of the internal space of the support frame body, so that the clamping column can fully fill the support frame body and improve the connection stability.

[0015] As a preferred technical solution, the width of the clamping column is equal to the width of the internal space of the support frame body, so that the clamping column can fully fill the support frame body and improve the connection stability.

[0016] As a preferred technical solution, the included angle between the end faces of the first frame edge and the second frame edge near the corner code and the side wall of the support frame body away from the photovoltaic panel is 45°. After the first frame edge and the second frame edge fixed and connected by the corner code are connected, the end faces of the first frame edge and the second frame edge can be closely attached to each other, have a supporting force between them, and cooperate with the supporting effect of the corner code to make the support and fixation of the photovoltaic panel frame to the photovoltaic panel more stable; and after the connection is completed, the corner code can be completely hidden in the support frame body, with high aesthetic degree.
