[0029] Embodiments of the present invention are described in detail below, and the embodiments described with reference to the accompanying drawings are exemplary.

[0030] Reference below Figure 1-Figure 4 A frame 100 of a photovoltaic module according to an embodiment of the present invention is described.

[0031] like Figure 1 and Figure 2 As shown, the frame 100 of the photovoltaic component according to the first embodiment of the utility model includes: an outer frame 10, a first inner frame 20 and a second inner frame 30, the first inner frame 20 is arranged on the inner side of the outer frame 10, and the first inner frame 20 and the outer frame 10 are integrally formed, one end of the first inner frame 20 is connected to one end of the outer frame 10, and the first inner frame 20 is bent relative to the outer frame 10, the first inner frame 20 is formed with a mounting groove 21, the mounting groove 21 is used to install the photovoltaic panel, the other end of the first inner frame 20 is formed with a bite groove 226, the second inner frame 30 is arranged on the inner side of the outer frame 10, and the second inner frame 30 and the outer frame 10 are integrally formed, one end of the second inner frame 30 is connected to the other end of the outer frame 10, and is bent relative to the outer frame 10, the other end of the second inner frame 30 is provided with a bite portion 31, and the bite portion 31 is arranged in the bite groove 226.

[0032] Specifically, the frame of a traditional photovoltaic module is formed by cold bending of the sheet. This has the problem of insufficient bite strength at the edge where the sheet is cold bent, and the edge where the sheet is cold bent is generally set close to the outside. This makes it easy to loosen under external force impact, reducing the strength of the frame.

[0033] Therefore, the frame 100 of the photovoltaic module is mainly composed of an outer frame 10, a first inner frame 20 and a second inner frame 30. The first inner frame 20 is folded and arranged on the inner side of the outer frame 10, so as to increase the strength of the outer frame 10 and the strength and rigidity of the mounting groove 21. In addition, the first inner frame 20 is integrally formed with the outer frame 10, so as to facilitate the bending of the first inner frame 20 relative to the outer frame 10, and the second inner frame 20 is integrally formed with the outer frame 10, so as to facilitate the bending of the second inner frame 20 relative to the outer frame 10, and can also be quickly integrally formed. A bite groove 226 is formed at the other end of the first inner frame 20, which can facilitate the bite portion 31 set at the other end of the second inner frame 30 to extend into the bite groove 226, and then be pressed and fitted through riveting. In this way, the bite groove 226 can wrap the bite portion 31, which can not only protect the bite portion 31, but also make the connection between the bite portion 31 and the bite groove 226 more stable and firm, and can also increase the strength of the connection between the bite portion 31 and the bite groove 226.

[0034] Furthermore, the bite portion 31 and the bite groove 226 are both arranged at the bottom position of the first inner frame 20. In this way, not only can interference be avoided, but also the bite portion 31 and the bite groove 226 can be protected, thereby ensuring the strength and rigidity of the connection between the bite portion 31 and the bite groove 226.

[0035] Therefore, the frame 100 of the photovoltaic module can protect the bite portion 31, make the connection between the bite portion 31 and the bite groove 226 more stable and firm, and increase the strength of the connection between the bite portion 31 and the bite groove 226.

[0036] According to some embodiments of the present invention, Figure 1 As shown, the first inner frame 20 includes: a mounting portion 22 and a bending portion 23, one end of the mounting portion 22 is connected to one end of the outer frame 10, and the mounting portion 22 is bent relative to the outer frame 10, the mounting portion 22 forms a mounting groove 21, the bending portion 23 is connected to the other end of the mounting portion 22, and the bending portion 23 and the mounting portion 22 together form a bite groove 226.

[0037] The first inner frame 20 is mainly composed of a mounting portion 22 and a bending portion 23. The mounting portion 22 is bent relative to the outer frame 10, so that the mounting portion 22 and the outer frame 10 are connected to form a double-layer structure. The mounting portion 22 and the outer frame 10 are pressed together to increase the strength of the first inner frame 20. The installation groove 21 is provided to facilitate the installation of the photovoltaic panel. In addition, the bending portion 23 is bent relative to the mounting portion 22 to form a bite groove 226, so that the bite portion 31 can be inserted easily.

[0038] According to some embodiments of the present invention, Figure 3 As shown, the mounting portion 22 includes: a first top plate 221, a first side plate 222 and a first bottom plate 223, the first top plate 221 is connected to one end of the outer frame 10, and the first top plate 221 is bent relative to the outer frame 10, one end of the first side plate 222 is connected to the other end of the first top plate 221, and the first side plate 222 is bent relative to the first top plate 221, the first top plate 221 and the first side plate 222 are attached to the outer frame 10, the first bottom plate 223 is connected to the other end of the first side plate 222, and the first bottom plate 223 is bent relative to the first side plate 222, the first top plate 221, the first side plate 222 and the first bottom plate 223 jointly form a mounting groove 21, and the bending portion 23 is connected to the other end of the first bottom plate 223.

[0039] Among them, the mounting portion 22 is mainly composed of a first top plate 221, a first side plate 222 and a first bottom plate 223. The mounting portion 22 is U-shaped. The first top plate 221 is connected to one end of the outer frame 10, and the first top plate 221 is bent relative to the outer frame 10. In this way, the first top plate 221 and the top of the outer frame 10 form a double-layer structure, thereby increasing the strength of the first top plate 221 and the top of the outer frame 10.

[0040] Furthermore, the first top plate 221 and the first side plate 222 are attached to the outer frame 10 , and the first side plate 222 and the outer frame 10 may also form a double-layer structure, thereby increasing the strength of the connection between the first side plate 222 and the outer frame 10 .

[0041] According to some embodiments of the present invention, Figure 1 As shown, the second inner frame 30 includes: a second bottom plate 32 and a second side plate 33, one end of the second bottom plate 32 is connected to the other end of the outer frame 10, and the second bottom plate 32 is bent relative to the outer frame 10, one end of the second side plate 33 is connected to the other end of the second bottom plate 32, and the second side plate 33 is bent relative to the second bottom plate 32, the bite portion 31 is connected to the other end of the second side plate 33, and the angle between the bite portion 31 and the second side plate 33 is an acute angle or a right angle.

[0042] Among them, the second bottom plate 32 can not only support the outer frame 10, but also support the second side plate 33. The bite portion 31 is connected to the other end of the second side plate 33. In this way, the distance between the bite portion 31 and the bite groove 226 can be shortened, thereby facilitating the connection and cooperation between the bite portion 31 and the bite groove 226.

[0043] Furthermore, the angle between the bite portion 31 and the second side plate 33 is an acute angle or a right angle. When the angle between the bite portion 31 and the second side plate 33 is a right angle, the bite portion 31, the first bottom plate 223 and a part of the bending portion 23 are arranged in parallel, so that the connection between the bite portion 31, the first bottom plate 223 and a part of the bending portion 23 can be smoother, and the contact area between the bite portion 31, the first bottom plate 223 and the bending portion 23 can be increased, so that the connection can be more stable and firm.

[0044] When the angle between the bite portion 31 and the second side plate 33 is an acute angle, the bite portion 31, the first bottom plate 223 and a part of the bending portion 23 are tilted, thereby preventing the connection between the bite portion 31, the first bottom plate 223 and a part of the bending portion 23 from loosening, thereby having a locking effect.

[0045] According to the specific embodiment of the utility model, Figure 2 and Figure 3As shown, the outer frame 10 includes: a second top plate 11, a third side plate 12 and a third bottom plate 13, one end of the second top plate 11 is connected to one end of the first top plate 221, the first top plate 221 is attached to the inner side of the second top plate 11, one end of the third side plate 12 is connected to the other end of the second top plate 11, and the third side plate 12 is bent relative to the second top plate 11, the first side plate 222 is attached to the inner side of the third side plate 12, one end of the third bottom plate 13 is connected to the other end of the third side plate 12, and the third bottom plate 13 is bent relative to the third side plate 12, and the second bottom plate 32 is attached to the inner side of the third bottom plate 13.

[0046] Specifically, the first top plate 221 is attached to the inner side of the second top plate 11, so that the first top plate 221 and the second top plate 11 form a double-layer structure, thereby increasing the strength of the top of the frame 100. Similarly, the first side plate 222 is attached to the inner side of the third side plate 12, and the second bottom plate 32 is attached to the inner side of the third bottom plate 13, thereby further increasing the strength of the frame 100.

[0047] According to a specific embodiment of the utility model, the first top plate 221 includes a first horizontal plate 224 and a first inclined plate 225, the first inclined plate 225 is connected to the first horizontal plate 224, and the first inclined plate 225 is inclined relative to the first horizontal plate 224, the second top plate 11 includes a second horizontal plate 14 and a second inclined plate 15, the second inclined plate 15 is connected to the second horizontal plate 14, and the second inclined plate 15 is inclined relative to the second horizontal plate 14, the first inclined plate 225 and the second inclined plate 15 are connected, the first horizontal plate 224 is attached to the inner side of the second horizontal plate 14, and the first inclined plate 225 is attached to the inner side of the second inclined plate 15.

[0048] Specifically, the first top plate 221 is mainly composed of a first horizontal plate 224 and a first inclined plate 225. When the photovoltaic panel is fixed in the mounting groove 21 by silicone, the first inclined plate 225 is tilted inwardly relative to the first horizontal plate 224, thereby preventing silicone from overflowing.

[0049] According to the specific embodiment of the utility model, Figure 3 As shown, the inclination angle of the first inclined plate 225 relative to the first horizontal plate 224 is α, and α satisfies the relationship: α≤15°.

[0050] Specifically, the inclination angle of the first inclined plate 225 relative to the first horizontal plate 224 does not exceed 15°, so the inclination angle of the first inclined plate 225 relative to the first horizontal plate 224 can be set to 10°, 12° and 14°, which can prevent excess silicone from overflowing, reduce the cleaning of the front of the photovoltaic module, and reduce labor costs.

[0051] According to the specific embodiment of the utility model, Figure 1 and Figure 3 As shown, the bending portion 23, the bite portion 31 and the portion of the first bottom plate 223 corresponding to the bending portion 23 are in surface contact with each other, thereby forming a three-layer bite structure parallel to each other.

[0052] Specifically, the bite portion 31, the first bottom plate 223 and the corresponding parts of the bending portion 23 are arranged parallel to each other, and the bite portion 31, the first bottom plate 223 and the corresponding parts of the bending portion 23 are stacked to form a three-layer structure parallel to each other. This can make the connection between the bite portion 31, the first bottom plate 223 and the bending portion 23 smoother, and can also increase the contact area between the bite portion 31, the first bottom plate 223 and the bending portion 23, so that the connection can be more stable and firm.

[0053] Furthermore, the corresponding parts of the bite portion 31, the first bottom plate 223 and the bending portion 23 can also be stacked to form at least a three-layer structure, thereby further improving the strength of the frame.

[0054] According to some embodiments of the present invention, a cavity 40 is formed between the outer frame 10, the first inner frame 20 and the second outer frame 10, and the cavity 40 is used to install the corner piece.

[0055] A closed cavity 40 is formed between the outer frame 10, the first inner frame 20 and the second outer frame 10, and the corner piece can extend into the cavity 40, so as to facilitate the fixed installation of the photovoltaic module as a whole.
