Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaics, and in particular to a photovoltaic component frame and a photovoltaic component. Background Art

[0002] With the continuous advancement of photovoltaic technology, photovoltaic modules—semiconductor devices that convert solar energy into electricity—have seen rapid development. A photovoltaic module consists of a laminate (from top to bottom: glass, encapsulation layer, cell layer, encapsulation layer, and backsheet or glass), a photovoltaic frame, and a junction box. The photovoltaic frame primarily serves to enhance the module's resistance to mechanical loads and facilitate its installation on the photovoltaic support. It also protects the four edges of the laminate from external impacts that could cause cracking and seals the edges to prevent moisture infiltration, which could affect module performance and reliability.

[0003] Existing photovoltaic modules primarily use aluminum or steel frames to protect the edges of the solar panels and enhance their structural strength. These frames also meet the needs of securing the solar panels, sealing the solar modules, enhancing module strength, extending their lifespan, and facilitating transportation and installation. Aluminum alloy frames currently account for 95% of the solar module market and contribute approximately 10% of the total cost of photovoltaic modules, making them the largest non-silicon raw material.

[0004] The existing frame structure is relatively complex, consisting of long and short frames, as well as corner brackets. These are manufactured through multiple processes, including extrusion, straightening, sandblasting, anodizing, and machining. At the module end, a machine aligns the long and short frames with the corner brackets before the PV modules are installed within the frame. This production process carries risks such as misaligned corner brackets and extrusion. Furthermore, the frame structure lacks internal support, making laminate collapse a risk.

[0005] For example, Chinese patent document CN213151988U discloses a lightweight photovoltaic frame comprising four frames, four connectors, and four reinforcements. The frame comprises a main body, with an upper edge and a support edge formed at the upper and middle portions of one side of the main body. The lower portions of the main body and the support edge form a first cavity, and the connectors comprise right-angle plates. This application utilizes angle brackets to connect the long and short frames, but suffers from complex frame installation steps, prone to installation deviation, and insufficient support for the laminate.

[0051] Example

[0052] Combine Figure 1 and Figure 2 A photovoltaic module frame according to this embodiment includes an outer frame 1. The outer frame 1 includes at least three edges, which are sequentially connected to form a closed polygonal structure. The outer frame 1 is integrally formed. Specifically, in this embodiment, the outer frame 1 is formed by sequentially connecting four edges to form a rectangular frame. The rectangular frame according to this embodiment is integrally injection molded using a plastic material.

[0053] Combine Figure 3-Figure 5 In this embodiment, the outer frame 1 includes a support portion 11, with two end surfaces of the support portion 11 defining a bearing surface 13 and a mounting surface 12. The bearing surface 13 is used to support the laminate, and the mounting surface 12 is used to connect to the photovoltaic module support. In this embodiment, the mounting surface 12 protrudes outward relative to the support portion 11, projecting toward the center of the outer frame 1. The mounting surface 12 protrudes inward from the bottom of the support portion 11. When the photovoltaic module is mounted on the support, it increases the mounting area of ​​the photovoltaic module and the support, making the installation more secure. It also reserves a fixed position for the photovoltaic module.

[0054] Combine Figure 4 、 Figure 13-15 In this embodiment, a limiting surface 15 is provided on the outer edge of the support portion 11, and the limiting surface 15 is provided perpendicular to the bearing surface 13 and is provided to protrude outward from the bearing surface 13. In this embodiment, a limiting surface 15 is provided on one side of the bearing surface 13 to prevent the laminate from protruding outside the frame after installation. In this embodiment, an overflow glue groove 14 is provided on the bearing surface 13, and the overflow glue groove 14 is provided close to the limiting surface 15. At the same time, the overflow glue groove 14 is connected to the bearing surface 13 by a transition surface, and the transition surface is a circular arc surface. The position where the overflow glue groove 14 is provided can also be set at other positions. In another embodiment, the overflow glue groove 14 is provided on the limiting surface 15.

[0055] To better support the laminate, this embodiment further includes a support beam 2 between any two sides of the outer frame 1; the support beam 2 is disposed within a closed polygonal structure. In this embodiment, the support beam 2 is mounted on a mounting surface 12, which supports the support beam 2.

[0056] In this embodiment, the support beam 2 includes a first connecting surface 21 and a second connecting surface 22, which are oppositely disposed. The first connecting surface 21 and the second connecting surface 22 are connected by two oppositely disposed side walls. The first connecting surface 21 is flush with the bearing surface 13. The flushness of the first connecting surface 21 and the bearing surface 13 of the support beam 2 in this embodiment ensures that the laminate is fully aligned with the outer frame 1 and the support beam 2 during installation, and prevents uneven installation of the laminate due to the arrangement of the support beam 2.

[0057] Figure 2 、 Figure 6-Figure 12 There are several different ways of arranging the support beams 2 in this embodiment. In this embodiment, the support beams 2 include a straight beam 23 and an oblique beam 24, wherein the straight beam 23 is arranged on two sides of the outer frame 1 that are not directly connected. The oblique beam 24 is arranged on two sides of the outer frame 1 that are directly connected. In this embodiment, the straight beam 23 connects the two opposite sides of the rectangular frame, and the oblique beam 24 connects the two right-angled sides of the rectangular frame. The straight beam 23 and the oblique beam 24 can be arranged separately or in combination. There are also many ways to arrange the straight beam 23. One or more straight beams 23 can be arranged. Multiple straight beams 23 can be staggered to form a mesh structure. The oblique beams 24 are generally arranged at the corners of the outer frame 1. For example, in the rectangular frame of this embodiment, four oblique beams 24 are arranged at the four corner positions of the rectangular frame. When the outer frame 1 is a polygon, the oblique beams 24 are also arranged at the corresponding corner positions.

[0058] The above is a schematic description of the present invention and its embodiments, which is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by this and, without departing from the inventive purpose of the present invention, designs a structure and embodiment similar to the technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
