Technical Field

[0001] This invention belongs to the field of photovoltaic technology, specifically relating to a photovoltaic frame and a photovoltaic module. Background Technology

[0002] Existing photovoltaic (PV) modules typically consist of a laminate and a PV frame surrounding the edge of the laminate. The edge of the laminate is housed within a mounting groove on the PV frame, and an adhesive is applied to the contact area between the laminate and the PV frame to stably bond them together. However, separating the laminate from the PV frame during PV module recycling is difficult, resulting not only in low recycling efficiency of the PV modules but also in the difficulty of recovering intact laminates.

[0003] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0011] In one or more embodiments of the present invention, the first reinforcing plate includes a fourth edge extending to the side plate and a fifth edge disposed on the opposite side of the fourth edge, and the third notch extends from the fourth edge to the fifth edge.

[0012] In another aspect, the present invention provides a photovoltaic module, which includes a laminate and a first photovoltaic frame mounted on two opposite edges of the laminate, wherein the length of the first photovoltaic frame is less than the length of its adjacent edge of the laminate, and the first photovoltaic frame adopts the aforementioned photovoltaic frame.

Detailed Implementation

[0025] To enable those skilled in the art to better understand the technical solutions of this invention, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this invention.

[0026] Example 1:

[0027] Reference Figures 1 to 3 As shown, this embodiment provides a photovoltaic frame 100, which includes a top plate 110, a bottom plate 120 disposed at the bottom of the top plate 110, a side plate 130 connecting the top plate 110 and the bottom plate 120, and a reinforcing plate 140 connecting the bottom plate 120 and the side plate 130. A mounting groove is formed between the top plate 110, the side plate 130 and the reinforcing plate 140. The mounting groove is used to accommodate the edge of the laminate 210. The top plate 110 has a plurality of first notches 111 that penetrate the top plate 110 in a vertical direction.

[0028] In this embodiment, after the first notch 111 is opened on the top plate 110, the contact area between the top plate 110 and the laminate 210 can be reduced, making it easier to separate the photovoltaic frame 100 from the laminate 210 when the laminate 210 is subsequently recycled.

[0029] Reference Figure 1 and Figure 3 As shown, the top plate 110 in this embodiment includes a first edge 112 extending to the side plate 130 and a second edge 113 disposed on the opposite side of the first edge 112. The first notch 111 extends from the first edge 112 to the second edge 113 to maximize the size of the first notch 111 and further reduce the contact area between the top plate 110 and the laminate 210.

[0030] Reference Figure 1 and Figure 3 As shown, in this embodiment, the side plate 130 has several second notches 131 that penetrate the side plate 130 horizontally and extend to the mounting groove. The second notches 131 can reduce the contact area between the side plate 130 and the laminate 210, and further reduce the difficulty of separating the photovoltaic frame 100 from the laminate 210.

[0031] It should be understood that, considering the second notch 131 is located on the side of the laminate 210, after the photovoltaic frame 100 and the laminate 210 are assembled, the second notch 131 can be selectively sealed. For example, a sealing structure can be formed at the second notch 131 by applying sealant, and the sealing structure can be used to seal the second notch 131. When recycling the laminate 210, the sealing structure is removed first, and then the photovoltaic frame 100 and the laminate 210 are separated.

[0032] To further increase the size of the second notch 131, the side plate 130 in this embodiment includes a third edge 132 extending to the top plate 110, and the second notch 131 extends to the third edge 132, that is, one side of the second notch 131 extends to the top plate 110.

[0033] Furthermore, in this embodiment, the first notch 111 extends to the third edge 132, and the first notch 111 communicates with the second notch 131, so as to expose more of the laminate 210 at the first notch 111 and the second notch 131, thereby reducing the contact area between the top plate 110 and the side plate 130 and the laminate 210.

[0034] Reference Figure 2 As shown, the reinforcing plate 140 in this embodiment includes a first reinforcing plate 141 parallel to the top plate 110 and a second reinforcing plate 142 perpendicular to the first reinforcing plate 141. An mounting groove is formed between the first reinforcing plate 141, the top plate 110, and the side plate 130. The first reinforcing plate 141 has several third notches 1411 penetrating vertically through it. The third notches 1411 reduce the contact area between the first reinforcing plate 141 and the laminate 210, further reducing the difficulty of separating the photovoltaic frame 100 from the laminate 210.

[0035] Reference Figure 2 and Figure 3 As shown, in this embodiment, the first reinforcing plate 141 includes a fourth edge 1412 extending to the side plate 130 and a fifth edge 1413 disposed on the opposite side of the fourth edge 1412. The third notch 1411 extends from the fourth edge 1412 to the fifth edge 1413 to increase the size of the third notch 1411 as much as possible, thereby further reducing the contact area between the first reinforcing plate 141 and the laminate 210.

[0036] Example 2:

[0037] Reference Figure 4 As shown, this embodiment provides a photovoltaic module 200, which includes a laminate 210 and a first photovoltaic frame 220 installed on two opposite edges of the laminate 210. The length of the first photovoltaic frame 220 is less than the length of the adjacent edge of the laminate 210. The first photovoltaic frame 220 adopts the photovoltaic frame 100 in Embodiment 1. The corresponding edge of the laminate 210 is received in the mounting groove of the first photovoltaic frame 220. The edge of the laminate 210 not covered by the mounting groove is coated with sealant for sealing treatment.

[0038] Example 3:

[0039] Reference Figure 5 As shown, this embodiment provides a photovoltaic module 200. The difference between this photovoltaic module 200 and Embodiment 2 is that it further includes a second photovoltaic frame 230 installed on two opposite edges of the laminate 210. The first photovoltaic frame 220 and the second photovoltaic frame 230 are installed on two adjacent edges of the laminate 210. The length of the second photovoltaic frame 230 is less than the length of its adjacent edge of the laminate 210. The second photovoltaic frame 230 adopts the photovoltaic frame 100 in Embodiment 1. The corresponding edge of the laminate 210 is received in the mounting groove of the second photovoltaic frame 230.

[0040] Example 4:

[0041] Reference Figure 6 As shown, this embodiment provides a photovoltaic module 200. The difference between this photovoltaic module 200 and Embodiment 3 is that it has multiple spaced first photovoltaic frames 220 and multiple spaced second photovoltaic frames 230 on its corresponding edges.
