Technical Field

[0001] The present application relates to the technical field of photovoltaic modules, and in particular to a photovoltaic module frame and a photovoltaic module. Background Art

[0002] With the development of the photovoltaic industry, the installed capacity of solar photovoltaic has been growing almost linearly in recent years, and the recycling problem of photovoltaic modules after the warranty expires has also emerged. Photovoltaic modules contain rare metals such as silver, tellurium, indium, gallium, as well as silicon, glass, aluminum, EVA glue and other usable resources, which have high recycling value.

[0003] In the related art, when recycling photovoltaic modules, the frame and junction box of a photovoltaic module are generally removed first, and then the frameless module is mechanically crushed, and then the crushed particles are separated. In the process of disassembling the frame of the photovoltaic module, since the frames of each side of the photovoltaic module are connected by corner codes, the corner codes need to be removed first when disassembling. However, in the related art, it is difficult to disassemble the frame and the corner codes, resulting in a time-consuming and labor-intensive process of disassembling the frame. Utility Model Content

[0004] The present application provides a photovoltaic module frame and a photovoltaic module to solve the technical problem of time-consuming and labor-intensive frame disassembly during photovoltaic module recycling in the related art.

[0005] In order to solve the above problems, the present application provides a photovoltaic module frame, the photovoltaic module frame comprising:

[0006] A frame body, forming a cavity structure, wherein the cavity structure has a first side wall and a second side wall opposite to each other, wherein the first side wall is used for supporting the laminate;

[0007] The bottom plate is connected to the side of the second side wall facing away from the first side wall. One of the bottom plate and the second side wall is provided with a connecting groove, and the other is provided with a connecting protrusion matched with the connecting groove.

[0008] In some embodiments, the cavity structure further comprises a third side wall and a fourth side wall which are arranged opposite to each other, wherein the connection between the third side wall and the second side wall forms a first connection position, and the connection between the fourth side wall and the second side wall forms a second connection position;

[0009] The distribution position of the connection grooves on the second side wall corresponds to the first connection position and / or the second connection position.

[0010] In some embodiments, in a direction perpendicular to the second side wall, the connecting groove extends to the third side wall and / or the fourth side wall.

[0011] In some embodiments, in a direction perpendicular to the second side wall, an extension dimension of the connecting protrusion accounts for 20%-100% of an extension dimension of the third side wall or the fourth side wall.

[0012] In some embodiments, the thickness of the connecting protrusion accounts for 50% to 90% of the thickness of the third sidewall or the fourth sidewall.

[0013] In some embodiments, the connecting protrusion and the base plate are integrally formed.

[0014] In some embodiments, the opposing surfaces of the first side wall and the second side wall each have a corner friction area.

[0015] In some embodiments, the roughness of the angle code friction zone is 3mm-15mm.

[0016] In some embodiments, the photovoltaic module frame further includes:

[0017] A pressing plate is detachably connected to the first side wall, and a mounting groove is formed between the pressing plate and the first side wall, and the mounting groove is used to install the laminate.

[0018] The present application also provides a photovoltaic assembly, the photovoltaic assembly comprising:

[0019] Any photovoltaic module frame as described above;

[0020] A laminate, the edge of which is overlapped on the first side wall.

[0021] The beneficial effects of the embodiments of the present application are as follows: the photovoltaic module frame provided by the present application includes a frame body and a bottom plate. The frame body forms a cavity structure, and the cavity structure has a first side wall and a second side wall opposite to each other, and the first side wall is used to support the laminate. The bottom plate is connected to the side of the second side wall facing away from the first side wall, and one of the bottom plate and the second side wall is provided with a connecting groove, and the other is provided with a connecting protrusion that cooperates with the connecting groove. By detachably connecting the bottom plate of the photovoltaic module frame to the side of the second side wall facing away from the first side wall through the connecting groove and the connecting protrusion, when removing the corner code connecting each frame, the bottom plate can be removed from the second side wall of the frame body first, reducing the stress of the second side wall, and facilitating the removal of the corner code from the cavity structure, thereby simplifying the disassembly of the frame and shortening the working time of the frame disassembly during the recycling process of the photovoltaic module.

[0022] When a connecting groove is provided on the second side wall and extends to the third side wall and / or the fourth side wall, after the bottom plate is removed, the connecting groove can further reduce the stress of the third side wall and the fourth side wall, further facilitating the removal of the angle code from the cavity structure.

[0023] When the pressure plate of the photovoltaic module frame is also connected to the first side wall in a detachable manner, when the laminate is removed from the frame during the recycling of the photovoltaic modules, the pressure plate can be removed from the first side wall first, and then the laminate can be removed from the first side wall, thereby avoiding the breakage of the surface glass of the laminate due to the use of brute force to pull the laminate out from between the pressure plate and the first side wall, thereby reducing the safety hazards during the disassembly of the photovoltaic modules.

[0037] 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.

[0038] See also Figure 1 and Figure 2 The present application provides a photovoltaic module frame 100, which includes a frame body 10 and a bottom plate 20. The frame body 10 forms a cavity structure 15, and the cavity structure 15 has a first side wall 11 and a second side wall 12 opposite to each other, and the first side wall 11 is used to support the laminate 200. The bottom plate 20 is connected to the side of the second side wall 12 facing away from the first side wall 11, and one of the bottom plate 20 and the second side wall 12 is provided with a connecting groove 16, and the other is provided with a connecting protrusion 21 that matches the connecting groove 16.

[0039] The frame body 10 can be a profile with a cavity structure 15. The present application does not limit the specific shape of the cavity structure 15. For example, the cavity structure 15 of the photovoltaic component frame 100 is generally rectangular, and the embodiments of the present application are also described by taking the cavity structure 15 as a rectangle as an example. It can be understood that the cavity structure 15 also has a third side wall 13 and a fourth side wall 14 relative to each other, and the first side wall 11, the second side wall 12, the third side wall 13 and the fourth side wall 14 form a rectangular cavity structure 15. When the photovoltaic component frame 100 is matched with the laminate 200, the edge of the laminate 200 is embedded in the laminate 200 installation groove 40 of the photovoltaic component frame 100. Taking the placement state of the photovoltaic component during normal use as an example, correspondingly, the lower surface of the laminate 200 overlaps the first side wall 11. It should be noted that when the edge of the laminate 200 is inserted into the installation groove 40 of the laminate 200, adhesive will be filled in the installation groove 40 of the laminate 200 first. It can be understood that there is adhesive between the first side wall 11 and the laminate 200.

[0040] The bottom plate 20 is connected to the side of the second side wall 12 facing away from the first side wall 11. The bottom plate 20 is used for punching holes to facilitate the fasteners to penetrate the punched holes to fix the photovoltaic module on the mounting frame. It should be noted that since the bottom plate 20 itself has a certain thickness, when the bottom plate 20 is connected to the side of the second side wall 12 facing away from the first side wall 11, it is equivalent to the bottom plate 20 increasing the thickness of the second side wall 12. Under the condition that the overall strength of the photovoltaic module frame 100 can be guaranteed, the thickness of the second side wall 12 itself can be relatively reduced. After the bottom plate 20 is removed from the second side wall 12, it is equivalent to reducing the thickness of the second side wall 12, thereby reducing the stress of the second side wall 12, and then facilitating the removal of the angle code from the cavity structure 15.

[0041] One of the bottom plate 20 and the second side wall 12 is provided with a connection groove 16, and the other is provided with a connection protrusion 21 that cooperates with the connection groove 16. The bottom plate 20 and the second side wall 12 are detachably connected by the connection groove 16 and the connection protrusion 21. It should be noted that the detachable connection in the embodiment of the present application refers to a detachable connection after the bonding force of the adhesive is destroyed. In order to ensure the overall strength of the photovoltaic module frame 100, it can be understood that when the connection protrusion 21 and the connection groove 16 cooperate, the gap between the connection protrusion 21 and the connection groove 16 is also filled with adhesive. For example, before the connection protrusion 21 is inserted into the connection groove 16, the connection groove 16 is first filled with adhesive. For example, the adhesive can be Siland U801, Tianshan 1527, etc., but is not limited to this. When disassembling, the bottom plate 20 can be separated from the frame body 10 by knocking hard on the cantilever of the bottom plate 20.

[0042] In addition, by connecting the frame body 10 and the bottom plate 20 in the photovoltaic module frame 100 through the connecting groove 16 and the connecting protrusion 21, when the photovoltaic module is subsequently installed in a block-type manner, the bottom plate 20 can also be removed and installed, while also reducing the overall cost of the photovoltaic module.

[0043] Please also read Figure 3In some embodiments, the connection groove 16 is provided on the second side wall 12, and the connection protrusion 21 is provided on the bottom plate 20. The connection between the third side wall 13 of the cavity structure 15 and the second side wall 12 forms a first connection position, and the connection between the fourth side wall 14 and the second side wall 12 forms a second connection position. The distribution position of the connection groove 16 on the second side wall 12 corresponds to the first connection position and / or the second connection position. After the bottom plate 20 is removed, the stress at the two corners of the cavity structure 15 can be weakened, further facilitating the removal of the corner code. It should be noted that two or one connecting groove 16 can be provided. When two connecting grooves 16 are provided, one connecting groove 16 is distributed at a position corresponding to the first connecting position, and the other connecting groove 16 is distributed at a position corresponding to the second connecting position; when one connecting groove 16 is provided, the connecting groove 16 is distributed at a position corresponding to the first connecting position or the second connecting position, wherein the distribution position of the connecting groove 16 on the second side wall 12 corresponds to the first connecting position and / or the second connecting position, which means that the width of the connecting groove 16 in the direction of the thickness D of the third side wall 13 and the fourth side wall 14 corresponds to the thickness D of the third side wall 13 and the fourth side wall 14, that is, the width of the connecting groove 16 is within the range of the thickness D of the third side wall 13 and the fourth side wall 14, and the thickness D of the third side wall 13 and the fourth side wall 14 is as follows: Figure 2 In the embodiment of the present application, two connecting grooves 16 are provided as an example for explanation, and correspondingly, two connecting protrusions 21 are also provided. In some embodiments, the connecting protrusion 21 and the bottom plate 20 are integrally formed.

[0044] In some embodiments, the connecting groove 16 extends to the third side wall 13 and / or the fourth side wall 14 in a direction perpendicular to the second side wall 12. Figure 2 and Figure 3 As shown, it is equivalent to that the connection groove 16 is opened on the third side wall 13 and / or the fourth side wall 14. After the bottom plate 20 is removed, the stress of the third side wall 13 and the fourth side wall 14 of the cavity structure 15 is reduced, which further facilitates the removal of the corner code from the cavity structure 15. In some embodiments, in order to ensure that the corner code can be removed from the cavity structure 15 and at the same time ensure the overall strength of the photovoltaic component frame 100, in the direction perpendicular to the second side wall 12, the extension dimension h of the connection protrusion 21 can account for 20%-100% of the extension dimension H of the third side wall 13 or the fourth side wall 14, for example, it can be 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90% or 100%, but it is not limited thereto. The thickness d of the connection protrusion 21 accounts for 50%-90% of the thickness D of the third side wall 13 or the fourth side wall 14, for example, it can be 50%, 60%, 70%, 80%, 90%, 100%, as shown in FIG. Figure 2 and Figure 3As shown, the thickness D of the third side wall 13 and the fourth side wall 14 and the thickness d of the connecting protrusion 21 are the dimensions thereof in the direction perpendicular to the third side wall 13 or the fourth side wall 14. It should be noted that, since the connecting groove 16 and the connecting protrusion 21 are also fixedly connected by adhesive, it can be understood that the dimensions of the connecting groove 16 in the direction perpendicular to the second side wall 12 and in the direction perpendicular to the third side wall 13 or the fourth side wall 14 are larger than the corresponding dimensions of the connecting protrusion 21, so that there is a gap between the connecting protrusion 21 and the connecting groove 16 after they are matched. For example, the wall thickness of the third side wall 13 and the fourth side wall 14 is 1.6 mm, the thickness of the connecting protrusion 21 can be 1.4 mm, and the wall thickness of the bottom plate 20 can be 1.54 mm. It should be noted that, in the implementation of this application, the example that the extension dimensions of the third side wall 13 and the fourth side wall 14 in the direction perpendicular to the second side wall 12 and the extension dimensions in the direction perpendicular to the third side wall 13 are the same is used for explanation.

[0045] In some embodiments, the connection groove 16 can also be provided on the bottom plate 20, and the corresponding connection protrusion 21 is provided on the second side wall 12. The connection protrusion 21 is provided on the side of the second side wall 12 facing away from the cavity structure 15. In the embodiment of the present application, there is no restriction on the distribution position of the connection protrusion 21 on the second side wall 12. For example, in order to avoid the connection protrusion 21 affecting the stress of the second side wall 12, the distribution position of the connection protrusion 21 can be made to correspond to the position of the third side wall 13 and / or the fourth side wall 14.

[0046] In addition, it should be noted that in the embodiments in which the connecting groove 16 is provided on the second side wall 12 and in the embodiments in which the connecting groove 16 is provided on the bottom plate 20, the connecting groove 16 may pass through the front and rear end surfaces of the third side wall 13 and / or the fourth side wall 14, or may not pass through the front and rear end surfaces of the third side wall 13 and / or the fourth side wall 14. Of course, it may also pass through only one of the front and rear end surfaces of the third side wall 13 and / or the fourth side wall 14.

[0047] like Figure 1 As shown, in some embodiments, the surfaces opposite to each other of the first side wall 11 and the second side wall 12 have a corner code friction area 18, which increases the friction between the cavity structure 15 and the corner code, and at the same time can ensure the stability of the connection between the corner code and the photovoltaic module frame 100. In some embodiments, the roughness of the corner code friction area 18 can be 3mm-15mm, for example, 3mm, 5mm, 7mm, 9mm, 11mm, 13mm or 15mm, but is not limited thereto.

[0048] like Figure 1 and Figure 4As shown, in some embodiments, the photovoltaic module frame 100 further includes a pressing plate 30, which is detachably connected to the first side wall 11, and a mounting groove 40 is formed between the pressing plate 30 and the first side wall 11, and the mounting groove 40 is used to install the laminate 200. Further, by detachably connecting the pressing plate 30 with the frame body 10, during the photovoltaic module recycling process, when the frame and the laminate 200 are separated, the pressing plate 30 can be removed from the first side wall 11 first, and then the laminate 200 can be removed from the first side wall 11, effectively avoiding the surface glass of the laminate 200 being broken due to the use of brute force to pull the laminate 200 out from between the pressing plate 30 and the first side wall 11, thereby reducing the safety hazards during the disassembly of the photovoltaic module. In the embodiments of the present application, there is no restriction on the specific connection method of the detachable connection between the pressing plate 30 and the first side wall 11. For example, in some embodiments, the pressing plate 30 is L-shaped, and one side wall of the pressing plate 30 is located above the first side wall 11. A slot 17 is provided on the side of the first side wall 11 facing away from the cavity structure 15, and the other side wall of the pressing plate 30 is inserted into the slot 17. Correspondingly, when the pressing plate 30 is inserted into the slot 17, the slot 17 is also filled with adhesive, so that the pressing plate 30 can be bonded and fixed in the slot 17. When removing the pressing plate 30, for example, a steel sheet can be used to pry the pressing plate 30 apart at the mating position of the pressing plate 30 and the laminate 200, but it is not limited to this. It should be noted that the slot 17 can be formed between two extending protrusions on the first side wall 11, but it is not limited to this.

[0049] It should be noted that, in some embodiments, when the photovoltaic module frame 100 does not include a pressure plate 30 detachably connected to the first side wall 11, the frame body 10 may also form a mounting groove 40, such as Figure 5 shown.

[0050] like Figure 6 and Figure 7 As shown, in some embodiments, the photovoltaic assembly further includes a laminate 200 and the photovoltaic assembly frame 100 in any of the above embodiments, and the laminate 200 is placed on the first side wall 11 of the photovoltaic assembly frame 100 .

[0051] Among them, Figure 6 As shown, in some embodiments, the laminate 200 is directly placed on the first side wall 11 of the photovoltaic module frame 100, and the edge of the light-receiving surface of the laminate 100 is not pressed. Figure 5 and Figure 7 As shown, in other embodiments, when the frame body 10 is formed with a mounting groove 40 or the photovoltaic module frame 100 further includes a pressing plate 30, the laminate 100 is placed on the first side wall 11, and the edge of the laminate 200 is simultaneously embedded in the mounting groove.

[0052] The photovoltaic assembly provided in the present application adopts all the technical solutions of all the embodiments of the photovoltaic assembly frame 100, and therefore at least has all the beneficial effects brought by the technical solutions of the embodiments of the photovoltaic assembly frame 100, which will not be described one by one here.

[0053] The above description is only an implementation method of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
