[0039] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0040] See also Figures 1 to 3 The present application provides a photovoltaic module frame 100, including an upper pressing piece 10 and a frame body 20. The upper pressing piece 10 has a first extension wall 11 and a second extension wall 12 opposite to each other. The frame body 20 forms a cavity structure 25, a side wall of the cavity structure 25 is a connecting wall 23, and a side of the connecting wall 23 away from the cavity structure 25 forms an embedding groove 26, and the second extension wall 12 is embedded in the embedding groove 26.

[0041] It should be noted that, in order to ensure the overall strength and stability of the photovoltaic module frame 100, the second extension wall 12 is embedded in the embedding groove 26. It can be understood that after the second extension wall 12 is embedded in the embedding groove 26, the upper pressure piece 10 and the frame body 20 are relatively fixed, for example, they can be bonded, riveted or connected with threaded fasteners, but are not limited to this. In the embodiment of the present application, the second extension wall 12 is embedded in the embedding groove 26 and then bonded and fixed as an example. For example, before the second extension wall 12 is embedded in the embedding groove 26, the embedding groove 26 can be filled with adhesive, and then the second extension wall 12 can be embedded in the embedding groove 26 to complete the connection between the upper pressure piece 10 and the frame body 20.

[0042] The upper pressing member 10 has a first extension wall 11 and a second extension wall 12 opposite to each other, the second extension wall 12 is connected to the frame body 20, and a mounting groove 14 of the laminate is formed between the first extension wall 11 and the second extension wall 12, that is, when the laminate is matched with the photovoltaic module frame 100 provided by the present application, the edge of the laminate is embedded between the first extension wall 11 and the second extension wall 12. It can be understood that one end of the first extension wall 11 and the second extension wall 12 forms an opening of the mounting groove 14, and the other end is connected by a vertical side wall 13.

[0043] The frame body 20 may be a profile having a cavity structure 25. The present application does not limit the specific shape of the cavity structure 25. For example, the cavity structure 25 of the photovoltaic module frame 100 is generally rectangular. The embodiments of the present application are also described by taking the cavity structure 25 as a rectangle as an example. It can be understood that the cavity structure 25 has side walls in at least four directions. The placement state of the photovoltaic module frame 100 during normal use is used as an example. The cavity structure 25 has side walls in four directions: upper, lower, left, and right. The upper pressure piece 10 is located above the frame body 20. It can be understood that the side wall above the cavity structure 25 is the connecting wall 23.

[0044] like Figure 3As shown, in some embodiments, the embedding groove 26 includes a supporting bottom surface 261 and a limiting side surface 262 located on one side of the supporting bottom surface 261, the supporting bottom surface 261 cooperates with a side surface of the second extension wall 12 away from the first extension wall 11, and the limiting side surface 262 cooperates with the end surface of the second extension wall 12. Wherein, without considering the adhesive between the second extension wall 12 and the embedding groove 26, the supporting bottom surface 261 cooperates with a side surface of the second extension wall 12 away from the first extension wall 11 means that the supporting bottom surface 261 and the side surface of the second extension wall 12 away from the first extension wall 11 are in contact with each other, and correspondingly, the limiting side surface 262 cooperates with the end surface of the second extension wall 12 means that the limiting side surface 262 and the end surface of the second extension wall 12 are in contact with each other. By providing the limiting side surface 262 on one side of the supporting bottom surface 261, when the second extension wall 12 is engaged with the embedding groove 26, the limiting side surface 262 can play a role in positioning and installation, so that the upper pressing piece 10 and the frame body 20 can be quickly engaged in place. As shown in FIG. Figure 3 As shown, a side area of ​​the connecting wall 23 away from the surface of one side of the cavity structure 25 is sunken to form a supporting bottom surface 261 of the embedding groove 26, and correspondingly, the other side area relative to the supporting bottom surface 261 is a boss structure 28, and a side surface of the boss structure 28 facing the supporting bottom surface 261 forms a limiting side surface 262. After the second extension wall 12 is embedded in the embedding groove 26, the upper surface of the boss structure 28 can be flush with the side surface of the second extension wall 12 close to the first extension wall 11, but it is not limited thereto.

[0045] The matching limiting side surface 262 and the end surface of the second extension wall 12 can be a vertical plane, an inclined plane or an arc surface, but are not limited thereto. In some embodiments, the matching limiting side surface 262 and the end surface of the second extension wall 12 are both arc surfaces. On the one hand, the limiting side surface 262 and the end surface of the second extension wall 12 are arc surfaces, which can increase the matching area between the two and ensure the stability of the bonding between the upper pressure piece 10 and the frame body 20; on the other hand, when the end surface of the second extension wall 12 includes a downwardly inclined arc surface, after the end surface of the second extension wall 12 cooperates with the limiting side surface 262, in the vertical direction, the limiting side surface 262 can also limit the upward movement of the second extension wall 12, ensuring the overall pulling performance of the photovoltaic module frame 100 in the vertical direction. For example, in some embodiments, the limiting side surface 262 and the end surface of the second extension wall 12 can both be half arc surfaces, that is, the bonding area between the end surface of the second extension wall 12 and the limiting side surface 262 can be guaranteed, and the limiting side surface 262 can limit the upward movement of the end of the second extension wall 12.

[0046] Please also read Figures 4 to 6In other embodiments, the embedding groove 26 may further include a first limiting wall surface 263 and a second limiting wall surface 264. The first limiting wall surface 263 is located on the side of the second extension wall 12 close to the first extension wall 11, and the second limiting wall surface 264 is located on the side of the second extension wall 12 away from the first extension wall 11. This is equivalent to embedding the second extension wall 12 between the first limiting wall surface 263 and the second limiting wall surface 264 in the vertical direction. In this way, the first limiting wall surface 263 can limit the upward movement of the entire second extension wall 12 in the vertical direction, thereby ensuring the overall pulling performance of the photovoltaic module frame 100.

[0047] It should be noted that, since the second extension wall 12 in the upper pressing member 10 is connected to the first extension wall 11 through a vertical side wall 13, it can be understood that a notch is formed at one end of the first limiting wall surface 263 and the second limiting wall surface 264, so that the second extension wall 12 can be embedded between the first limiting wall surface 263 and the second limiting wall surface 264. In some embodiments, a barb groove 265 is formed on the first limiting wall surface 263 and / or the second limiting wall surface 264, and a barb structure 121 that cooperates with the barb groove 265 is formed on the second extension wall 12. The barb structure 121 is used to limit the second extension wall 12 from moving in the direction of the notch, further ensuring the stability of the upper pressing member 10 and the frame body 20. In order to enable the barb structure 121 to cooperate with the barb groove 265 when the second extension wall 12 is embedded between the first extension wall 11 and the second extension wall 12, the embedding groove 26 can be a through groove. In the embodiment of the present application, there is no limitation on the barb structure 121 and the location of the barb structure 121 on the second extension wall 12. It can be understood that the shape of the barb groove 265 and the location of the barb groove 265 on the first limiting wall surface 263 and / or the second limiting wall surface 264 correspond to each other. For example, Figure 5 and Figure 6 As shown, in one embodiment, the barb structure 121 is formed at the end of the second extension wall 12, and the barb groove 265 is formed on the first limiting wall surface 263, correspondingly located at an end of the first limiting wall surface 263 away from the notch.

[0048] like Figure 3As shown, in some embodiments, the cavity structure 25 further comprises a bottom wall 24 and a first side wall 21 and a second side wall 22 which are arranged opposite to each other. The bottom wall 24 is arranged opposite to the connecting wall 23, and the connecting wall 23, the bottom wall 24, the first side wall 21 and the second side wall 22 surround the cavity structure 25. The bottom wall 24 has a connecting groove 27 on the side away from the connecting wall 23, and the connecting groove 27 extends to the first side wall 21 and / or the second side wall 22. It should be noted that since the connecting wall 23, the bottom wall 24, the first side wall 21 and the second side wall 22 surround the cavity structure 25, the cavity structure 25 is a quadrilateral. It can be understood that the bottom wall 24 and the connecting wall 23 are arranged opposite to each other, which means that the bottom wall 24 and the connecting wall 23 form two opposite sides of the cavity structure 25. Correspondingly, the photovoltaic module frame 100 also comprises a bottom plate 30, and the bottom plate 30 has a connecting protrusion 31 which cooperates with the connecting groove 27. The bottom plate 30 is used for punching holes to facilitate the fasteners to penetrate the holes and fix the photovoltaic module on the mounting frame. It should be noted that, since the bottom plate 30 itself has a certain thickness, when the bottom plate 30 is connected to the side of the bottom wall 24 away from the connecting wall 23, it is equivalent to the bottom plate 30 increasing the thickness of the bottom wall 24. Under the condition that the overall strength of the photovoltaic module frame 100 can be guaranteed, the thickness of the bottom wall 24 itself can be relatively reduced. After the bottom plate 30 is removed from the bottom wall 24, it is equivalent to reducing the thickness of the bottom plate 30, thereby reducing the stress of the bottom wall 24, and then facilitating the removal of the corner code 200 from the cavity structure 25 of the photovoltaic module frame 100. In the recycling process of the photovoltaic module, the disassembly of the photovoltaic module frame 100 is simplified, and the working hours of the disassembly of the photovoltaic module frame 100 are shortened. In addition, by making the frame body 20 in the photovoltaic module frame 100 cooperate and connect through the connecting groove 27 and the connecting protrusion 31, when the photovoltaic module is subsequently installed in a block-type installation mode, the bottom plate 30 can also be removed and installed for use, while also reducing the overall cost of the photovoltaic module.

[0049] In the embodiment of the present application, two connection grooves 27 are provided as an example for explanation. Correspondingly, one connection groove 27 extends to the first side wall 21, and the other connection groove 27 extends to the second side wall 22, which is equivalent to the connection groove 27 being formed on the first side wall 21 and the second side wall 22, extending along the height of the first side wall 21 and the second side wall 22, and the opening of the connection groove 27 is located on one side of the bottom wall 24, that is, the cavity structure on the first side wall 21 and the second side wall 22 forms the connection groove 27. After the bottom plate 30 is removed, the stress of the first side wall 21 and the second side wall 22 is also reduced accordingly, further facilitating the removal of the angle code 200 from the cavity structure 25.

[0050] like Figure 7As shown, in some embodiments, the present application also provides a corner code 200 for connecting the photovoltaic component frame 100 in any of the above embodiments. During the assembly of the photovoltaic component, each edge of the laminate is embedded in the photovoltaic component frame 100, and then the corner code 200 connects two adjacent photovoltaic component frames 100.

[0051] The corner code 200 includes a first connecting arm 201 and a second connecting arm 202 connected to each other. A plurality of protrusions are distributed on the end faces of the first connecting arm 201 and the second connecting arm 202. The protrusions are used to cooperate with the inner wall surface of the cavity structure 25 close to the upper pressing piece 10 and / or away from the inner wall surface of the upper pressing piece 10. The placement state of the photovoltaic component frame 100 during normal use is used as an example for explanation. The end faces of the first connecting arm 201 and the second connecting arm 202 are the upper and lower end faces. In the embodiment of the present application, the upper and lower end faces of the first connecting arm 201 and the second connecting arm 202 are provided with a plurality of protrusions 203 as an example for explanation. The protrusions may be cylindrical, sheet-like, triangular or arc-shaped, but are not limited thereto. When the corner code 200 connects two adjacent photovoltaic component frames 100, the first connecting arm 201 is inserted into the cavity structure 25 of one photovoltaic component frame 100, and the second connecting arm 202 is inserted into the cavity structure 25 of the other photovoltaic component frame 100. By providing a protrusion on the end surface of the first connecting arm 201 and the second connecting arm 202, when the first connecting arm 201 and the second connecting arm 202 are inserted into the cavity structure 25, the friction between the corner code 200 and the inner wall of the cavity structure 25 is increased. In some embodiments, the protrusion is an arc-shaped protrusion 203, wherein the arc-shaped protrusion 203 can be formed by a curved plate-like structure, and the arc-shaped protrusion 203 can be squeezed and deformed during insertion to increase the friction between the corner code 200 and the inner wall of the cavity structure 25, so that the arc-shaped protrusion 203 can be integrally formed with the corner code 200. Of course, the arc-shaped protrusion 203 can also be made of rubber. In the embodiment of the present application, the protrusion is an arc-shaped protrusion 203 as an example for explanation.

[0052] In some embodiments, the first connecting arm 201 and the second connecting arm 202 of the angle code 200 both have a free end 204 and a connecting end 205. From the free end 204 to the connecting end 205, the radial dimensions of the plurality of arc-shaped protrusions 203 gradually increase. It should be noted that the first connecting arm 201 and the second connecting arm 202 of the angle code 200 are connected to each other, and the end where the first connecting arm 201 and the second connecting arm 202 are connected to each other is its connecting end 205, and the end away from the connecting end 205 is its free end 204. When the first connecting arm 201 and the second connecting arm 202 are inserted into the cavity structure 25, the free end 204 is first inserted into the cavity structure 25, and by gradually increasing the radial dimensions of the plurality of arc-shaped protrusions 203 from the free end 204 to the connecting end 205, on the one hand, the plurality of arc-shaped protrusions 203 can play a certain guiding role, and on the other hand, the stability of the connection between the angle code 200 and the photovoltaic module frame 100 can be improved.

[0053] In some embodiments, the present application also provides a photovoltaic component, including a laminate, the photovoltaic component frame 100 in the above embodiment, and the corner code 200 in the above embodiment, wherein the edge of the laminate is embedded between the first extension wall 11 and the second extension wall 12, and the corner code 200 connects two adjacent photovoltaic component frames 100.

[0054] The photovoltaic module provided in the present application adopts all the technical solutions of all the embodiments of the photovoltaic module frame 100 and all the technical solutions of all the embodiments of the corner code 200, and therefore has at least all the beneficial effects brought by the technical solutions of the embodiments of the photovoltaic module frame 100, which will not be described one by one here.

[0055] The above description is only an implementation method of the present application, and does not limit the patent scope of the present application.
