[0030] Embodiments of the present invention are described in detail below, and the embodiments described with reference to the accompanying drawings are exemplary.

[0031] Reference below Figure 1 and Figure 2 A frame 100 of a photovoltaic assembly according to an embodiment of the present invention is described.

[0032] like Figure 1 and Figure 2 As shown, according to the frame 100 of the photovoltaic module of the first embodiment of the utility model, it includes: an outer frame 10 and an inner frame 20, the outer frame 10 includes an outer frame body 11 and a first bite portion 12, the first bite portion 12 is connected to one end of the outer frame body 11, and the first bite portion 12 is bent relative to the outer frame body 11, and a bite groove 13 is formed between the first bite portion 12 and the outer frame body 11, the inner frame 20 is arranged on the inner side of the outer frame 10, and the inner frame 20 is integrally formed with the outer frame 10, the inner frame 20 includes an inner frame body 21, a second bite portion 22 and a third bite portion 23, one end of the inner frame body 21 is connected to the other end of the outer frame body 11, and the inner frame body 21 is bent relative to the outer frame body 11. The inner frame body 21 is bent and formed with an installation groove, which is used to install the photovoltaic module. One end of the second bite portion 22 is connected to the other end of the inner frame body 21, and the second bite portion 22 is bent relative to the inner frame body 21. One end of the third bite portion 23 is connected to the other end of the second bite portion 22. The third bite portion 23 is attached between the second bite portion 22 and the inner frame body 21, and the third bite portion 23 is parallel to the second bite portion 22. At least a portion of the second bite portion 22 and at least a portion of the third bite portion 23 are arranged in the bite groove 13. The first bite portion 12, the second bite portion 22, the third bite portion 23 and the outer frame body 11 at least partially form a four-layer bite structure 31.

[0033] Specifically, the frames of traditional photovoltaic modules are curled multiple times at the edges formed by cold bending of sheets, which has the problems of complex process, great processing difficulty and high cost. In addition, multiple curling will cause stress concentration at the edges, which is prone to cracks and affects the quality and service life of the frame.

[0034] Therefore, a bite groove 13 is formed between the first bite portion 12 and the outer frame body 11 in the frame 100 of the photovoltaic module, so that a part of the second bite portion 22 and a part of the third bite portion 23 can be inserted into the bite groove 13, thereby facilitating the compression of the second bite portion 22 and the third bite portion 23. The inner frame 20 is integrally formed with the outer frame 10, and the inner frame 20 can be folded relative to the outer frame 10 to form a multi-layer structure, which can also facilitate rapid molding.

[0035] In addition, the second bite portion 22 is bent relative to the inner frame body 21, and the third bite portion 23 is bent relative to the second bite portion 22. The third bite portion 23 is located between the second bite portion 22 and the outer frame body 11, and the third bite portion 23 can be pressed to prevent the third bite portion 23 from loosening.

[0036] Further, the first bite part 12, the second bite part 22, the third bite part 23 and the outer frame body 11 form a four-layer bite structure 31, and the first bite part 12, the second bite part 22, and the third bite part 23 are stacked to form a three-layer structure, thereby increasing the strength of the bite of the frame 100. To prevent the bite from loosening, at least part of the first bite part 12, the second bite part 22, the third bite part 23 and the outer frame body 11 form a four-layer bite structure 31, or all of them can form a four-layer bite structure 31. Not only can the strength of the frame 100 be further improved, but also the bite can be prevented from loosening, and it also has the advantages of simple processing and reduced cost.

[0037] Therefore, at least a portion of the second bite portion 22 and at least a portion of the third bite portion 23 in the frame 100 of the photovoltaic component are arranged in the bite groove 13, which can not only further improve the strength of the frame 100, but also prevent the bite from loosening, and also has the advantages of simple processing and reduced cost.

[0038] According to some embodiments of the present invention, Figure 2 As shown, the outer frame body 11 includes: a first top plate 111, a first side plate 112 and a first bottom plate 113, the first side plate 112 is bent and connected between the first top plate 111 and the first bottom plate 113, the first bite portion 12, the second bite portion 22, the third bite portion 23 and the first bottom plate 113 corresponding to the first bite portion 12 are surface-to-surface fitted, thereby forming a four-layer bite structure 31.

[0039] Among them, the first bite part 12, the second bite part 22, the third bite part 23 and the part of the first bottom plate 113 corresponding to the first bite part 12 are surface-to-surface fitted together, and are stacked to form a four-layer bite structure 31, which can increase the contact area between each other, reduce the force, avoid stress concentration, thereby avoiding cracks, and increase the strength of the frame 100 at the bite point.

[0040] According to some embodiments of the present invention, Figure 1 As shown, the width of the first bite portion 12 is smaller than that of the second bite portion 22, and the width of the second bite portion 22 is the same as that of the third bite portion 23. The portion of the second bite portion 22 located outside the bite groove 13, the portion of the third bite portion 23 located outside the bite groove 13, and the portion of the first bottom plate 113 corresponding to the second bite portion 22 are surface-to-surface fitted together to form a three-layer bite structure 30.

[0041] The width of the first bite portion 12 is smaller than that of the second bite portion 22, so that the first bite portion 12 can be easily bent, which has the advantages of simple processing and reduced cost. The width of the second bite portion 22 is the same as that of the third bite portion 23, so that the force between the second bite portion 22 and the third bite portion 23 can be more uniform.

[0042] In addition, the portion of the second bite portion 22 located outside the bite groove 13, the portion of the third bite portion 23 located outside the bite groove 13, and the portion of the first bottom plate 113 corresponding to the second bite portion 22 are surface-to-surface fitted together, and a three-layer bite structure 30 is formed through stacking, which can increase the strength of the bite portion of the frame 100.

[0044] Among them, the width d2 of the second bite portion 22 is greater than or equal to half of the width d1 of the first bottom plate 113, or the width d3 of the third bite portion 23 is greater than or equal to half of the width d1 of the first bottom plate 113. In this way, the contact area between the third bite portion 23 and the first bottom plate 113 can be increased, and the contact area between the second bite portion 22 and the third bite portion 23 can also be increased, thereby reducing the force and avoiding stress concentration at the bite.

[0045] According to some embodiments of the present invention, Figure 1 and Figure 2 As shown, the inner frame body 21 includes: a mounting portion 211 and a supporting portion 212.

In addition, the support portion 212 is located between the mounting portion 211 and the second bite portion 22, so as to support the connection between the mounting portion 211 and the second bite portion 22.

[0047] According to some embodiments of the present invention, the support portion 212 is spaced apart from the first side plate 112 , and a cavity 40 is formed between the first side plate 112 , the first bottom plate 113 , the mounting portion 211 and the support portion 212 , and the cavity 40 is used to mount the angle piece.

[0048] The corner piece can extend into the cavity 40 , thereby facilitating the overall fixed installation of the photovoltaic component frame 100 .

[0049] According to some embodiments of the present invention, Figure 2 As shown, the mounting portion 211 includes: a second top plate 213, a second side plate 214 and a second bottom plate 215, the second top plate 213 is connected to one end of the first top plate 111, and the second top plate 213 is bent relative to the first top plate 111, one end of the second side plate 214 is connected to the other end of the first top plate 111, and the second side plate 214 is bent relative to the first top plate 111, the second top plate 213 is attached to the first top plate 111, the second side plate 214 is attached to the first side plate 112, the second bottom plate 215 is connected to the other end of the second side plate 214, and the second bottom plate 215 is bent relative to the second side plate 214, the second top plate 213, the second side plate 214 and the second bottom plate 215 jointly form a mounting groove, and the second bottom plate 215 is connected to the support portion 212.

Thus, the mounting portion 211 and the outer frame 10 are stacked, thereby improving the strength of the mounting portion 211 , and the support portion 212 can support the second bottom plate 215 .

[0051] According to some embodiments of the present invention, Figure 2 As shown, the first top plate 111 includes a first horizontal plate 1112 and a first inclined plate 1113, the first inclined plate 1113 is connected to the first horizontal plate 1112, and the first inclined plate 1113 is inclined relative to the first horizontal plate 1112, the second top plate 213 includes a second horizontal plate 2131 and a second inclined plate 2132, the second inclined plate 2132 is connected to the second horizontal plate 2131, and the second inclined plate 2132 is inclined relative to the second horizontal plate 2131, the first inclined plate 1113 and the second inclined plate 2132 are connected, the second horizontal plate 2131 is attached to the inner side of the first horizontal plate 1112, and the second inclined plate 2132 is attached to the inner side of the first inclined plate 1113.
