For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0033] The following describes a frame assembly 100 for a photovoltaic device according to an embodiment of the present utility model with reference to the accompanying drawings.

[0034] As Figures 1-6 shown, the frame assembly 100 for a photovoltaic device according to an embodiment of the present utility model includes a first frame 1 and a second frame 2. Among them, the first frame 1 includes a first body portion 11, and a part of the first body portion 11 is cut to form a first clamping portion 111. The second frame 2 includes a second body portion 21. One end in the length direction of the first body 11 and one end in the length direction of the second body portion 21 form an angle with each other. A part of the second body portion 21 is cut to form a second clamping portion 211, and the first clamping portion 111 and the second clamping portion 211 are clamped.

[0035] Thus, the direct connection between the first frame 1 and the second frame 2 is realized by clamping the first clamping portion 111 and the second clamping portion 211, and the detachable connection between the first frame 1 and the second frame 2 is realized, which is convenient for the maintenance and replacement of the first frame 1 and the second frame 2, and improves the production fault tolerance rate. At the same time, without other indirect connection structures, the connection between the two can be realized through the structures of the first frame 1 and the second frame 2 themselves, thereby reducing the assembly process of the frame assembly 100 and improving the assembly efficiency. In addition, there is no need to process and produce indirect connection structures, avoiding the manufacturing and assembly processes related to the indirect connection structures, reducing the error rate and scrap rate in the production and assembly processes, shortening the production cycle, reducing the production cost of the frame assembly 100, saving costs such as procurement and management, and avoiding the reduction of the quality of the frame assembly 100 caused by poor processing of the indirect connection structures, and improving the reliability of the frame assembly 100.

[0036] At the same time, by directly cutting the first body portion 11 to form the first clamping portion 111, the overall structure of the first frame 1 is made more compact, ensuring the overall structural strength of the first frame 1, and by directly cutting the second body portion 21 to form the second clamping portion 211, the overall structure of the second frame 2 is made more compact, ensuring the overall structural strength of the second frame 2, and reducing the number of additional connecting parts, effectively reducing the cost of the frame assembly 100.

[0037] In addition, by forming an angle between one end of the first body 11 in the length direction and one end of the second body 21 in the length direction, the first frame 1 and the second frame 2 are connected to each other while ensuring that the first frame 1 and the second frame 2 support and protect the laminate 200.

[0038] In some embodiments, the first frame 1 is an aluminum alloy member formed by an extrusion process, and the first clamping portion 111 is formed on the first body portion 11 by a stamping process.

[0039] In some embodiments, the second frame 2 is an aluminum alloy part formed by an extrusion process, and the second clamping portion 211 is formed on the second body portion 21 by a stamping process.

[0040] According to the frame assembly 100 for photovoltaic devices of the embodiment of the utility model, the first frame 1 includes a first main body portion 11, and the second frame 2 includes a second main body portion 21. One end of the first main body portion 11 in the length direction and one end of the second main body portion 21 in the length direction are at an angle to each other. The first clamping portion 111 is formed by partially cutting the first main body portion 11, and the second clamping portion 211 is formed by partially cutting the second main body portion 21. The first clamping portion 111 and the second clamping portion 211 are clamped to realize the direct connection between the first frame 1 and the second frame 2, and realize the detachable connection between the first frame 1 and the second frame 2, which is convenient for the maintenance and replacement of the first frame 1 and the second frame 2, and improves the production fault tolerance rate. At the same time, no other indirect connection structure is required, and the connection between the first frame 1 and the second frame 2 can be realized through their own structure, thereby reducing the assembly process of the frame assembly 100 and improving the assembly efficiency.

[0041] In some embodiments of the present invention, Figure 2 As shown, the first clamping portion 111 includes a first plate body 1111, the free end of the first plate body 1111 extends toward one side of the second frame 2 in the thickness direction of the first frame 1, and is inclined toward the side away from the second frame 2 in the length direction of the first frame 1, the second clamping portion 211 includes a second plate body 2111 and a bending portion 2112, the free end of the second plate body 2111 extends toward one side of the first frame 1 in the thickness direction of the second frame 2, and is inclined toward the side away from the first frame 1 in the length direction of the second frame 2, the bending portion 2112 is connected to one end of the second plate body 2111 away from the second frame 2 and extends toward the first frame 1, and the first plate body 1111 is clamped on the side of the bending portion 2112 facing the second frame 2.

[0042] It can be understood that during the assembly of the first frame 1 and the second frame 2, the first frame 1 is first fixed. Since the first plate 1111 and the second plate 2111 have a certain elastic deformation ability, during the movement of the second frame 2 toward the side of the first plate 1111 in the thickness direction of the first frame 1, the bending portion 2112 passes over the first plate 1111 and clamps the first plate 1111 on the side of the bending portion 2112 facing the second frame 2, thereby realizing the connection between the first clamping portion 111 and the second clamping portion 211, and then realizing the direct connection between the first frame 1 and the second frame 2, and ensuring the connection strength between the two, thereby ensuring the reliability of the frame assembly 100.

[0043] At the same time, when the first frame 1 and the second frame 2 need to be disassembled, since the first clamping portion 111 is formed by partially cutting the first main body portion 11, the first main body portion 11 has a mounting hole 112. The operator uses a sharp object to press against the second plate body 2111 through the mounting hole 112, so that the bending portion 2112 and the first plate body 1111 are separated, and then the second plate body 2111 is pulled outward to achieve the disassembly of the first frame 1 and the second frame 2.

[0044] In some embodiments of the present invention, Figures 2-4 As shown, the end where the first body portion 11 is connected to the second frame 2 has a first inclined surface 12, the end where the second body portion 21 is connected to the first frame 1 has a second inclined surface 22, and the first inclined surface 12 and the second inclined surface 22 are spliced. Thus, through such an arrangement, the first frame 1 and the second frame 2 can share the pressure on the photovoltaic device, so that the stress distribution of the frame assembly 100 is uniform, and the overall structural strength of the frame assembly 100 is effectively improved.

[0045] In some embodiments of the present invention, Figure 3 As shown, the first frame 1 is perpendicular to the second frame 2, the angle between the first inclined surface 12 and the length direction of the first frame 1 is a, and the angle between the second inclined surface 22 and the length direction of the second frame 2 is b, wherein a+b=90°.

[0046] It is understandable that, since the laminate 200 is square, the first frame 1 and the second frame 2 are arranged perpendicularly to ensure the support and protection of the laminate line by the frame assembly 100. At the same time, the angle between the first inclined surface 12 and the length direction of the first frame 1 and the angle between the second inclined surface and the length direction of the second frame 2 are 90 degrees, so that the first frame 1 and the second frame 2 are perpendicular, thereby ensuring the overall reliability of the frame assembly 100.

[0047] In some embodiments of the present utility model, 30° ≤ a ≤ 45°. It can be understood that since the angle between the first inclined surface 12 and the length direction of the first frame 1 is a, and the angle between the second inclined surface 22 and the length direction of the second frame 2 is b, and a + b = 90°.

[0048] Therefore, the angle b between the second inclined surface 22 and the length direction of the second frame 2 is b = 90° - a. By making the angle a between the first inclined surface 12 and the length direction of the first frame 1 satisfy 30° ≤ a ≤ 45°, while ensuring the structural strength of the frame assembly 100, the universality of the first frame 1 and the second frame 2 is improved, so as to adapt to different models or different installation sites, and the universality of the frame assembly 100 and the photovoltaic device applying the frame assembly 100 is improved. For example, the angle between the first inclined surface 12 and the length direction of the first frame 1 can be 30°, 35°, 40° or 45°.

[0049] In some embodiments of the present utility model, as Figure 2 shown, the first frame 1 further includes a first connection section 13 and a second connection section 14. The first connection section 13 and the second connection section 14 are arranged on one side of the first body portion 11 facing the second frame 2 in the thickness direction and are spaced apart along the height direction of the first body portion 11. The first connection section 13, the second connection section 14 and the first body portion 11 form a first installation groove 15 for fixing the laminate 200 of the photovoltaic device.

[0050] Therefore, by partially inserting the laminate 200 into the first installation groove 15, the first frame 1 supports and protects the laminate 200. At the same time, since the first installation groove 15 is formed by the first connection section 13, the second connection section 14 and the first body portion 11, the reliability of the first frame 1 is further improved.

[0051] In some embodiments of the present utility model, as Figure 2 shown, the second frame 2 further includes a third connection section 23 and a fourth connection section 24. The third connection section 23 and the fourth connection section 24 are arranged on one side of the second body portion 21 facing the first frame 1 in the thickness direction and are spaced apart along the height direction of the second body portion 21. The third connection section 23, the fourth connection section 24 and the second body portion 21 form a second installation groove 25 for fixing the laminate 200 of the photovoltaic device.

[0052] Therefore, by partially inserting the laminate 200 into the second installation groove 25, the second frame 2 supports and protects the laminate 200. At the same time, since the second installation groove 25 is formed by the third connection section 23, the fourth connection section 24 and the second body portion 21, the reliability of the second frame 2 is further improved.

[0053] In some embodiments of the present utility model, there is a first silicone layer between the outer surface of the laminate 200 located in the first mounting groove 15 and the inner wall of the first mounting groove 15. It can be understood that first, liquid silicone is sprayed on the inner wall surface of the first mounting groove 15, and then the laminate 200 is inserted into the first mounting groove 15. After the silicone is cured, the first silicone layer is formed to fix the first frame 1 and the laminate 200, and the first silicone layer effectively supports and protects the laminate 200.

[0054] In some embodiments of the present utility model, there is a second silicone layer between the outer surface of the laminate 200 located in the second mounting groove 25 and the inner wall of the second mounting groove 25. It can be understood that first, liquid silicone is sprayed on the inner wall surface of the second mounting groove 25, and then the laminate 200 is inserted into the second mounting groove 25. After the silicone is cured, the second silicone layer is formed to fix the second frame 2 and the laminate 200, and the first silicone layer effectively supports and protects the laminate 200.

[0055] In some embodiments of the present utility model, as Figure 6 shown, there are two first frames 1 that are opposite and spaced apart, and there are two second frames 2 that are opposite and spaced apart. The second clamping portions 21 of the two second frames 2 are all clamped with the first clamping portions 11 of the two first frames 1 and are located at both ends in the length direction of the first frame 1.

[0056] Thus, through such a setting, the two first frames 1 and the two second frames 2 form a square frame assembly 100, ensuring the support and protection of the frame assembly 100 for the laminate 200. At the same time, any two adjacent first frame 1 and second frame 2 are directly connected through their own structures, reducing the assembly process of the frame assembly 100 and improving the assembly efficiency. It should be noted that one second frame 2 is omitted in the figure, and only the laminate 200, the two first frames 1 and one second frame 2 are shown, and the laminate 200 is shown as a transparent structure in the schematic diagram.

[0057] Further, the length of the first frame 1 is greater than that of the second frame 2. Thus, during the assembly process of the frame assembly 100 and the laminate 200, first, liquid silicone is sprayed on the inner wall surfaces of the two first mounting grooves 15, and the laminate 200 is inserted into the two first mounting grooves 15. After the silicone cures, the fixation of the two first frames 1 and the laminate 200 is achieved. Then, the two second frames 2 are moved towards the laminate 200 so that the laminate 200 is located in the two second mounting grooves 25. Since the first plate body 1111 and the second plate body 2111 have a certain elastic deformation ability, during the movement of the second frame 2, the bending portion 2112 crosses over the first plate body 1111 and clamps the first plate body 1111 on the side of the bending portion 2112 facing the second frame 2, thereby realizing the connection between the first engaging portion 111 and the second engaging portion 211, and further realizing the direct connection between the first frame 1 and the second frame 2, and completing the assembly of the frame assembly 100 and the laminate 200.

[0058] In some embodiments, the first frame 1 is a metal part such as an aluminum alloy part or a plastic part, and / or the second frame 2 is a metal part such as an aluminum alloy part or a plastic part.

[0059] In some embodiments, the first frame 1 is an aluminum alloy part formed by an extrusion process, and / or the second frame 2 is an aluminum alloy part formed by an extrusion process.

[0060] In some embodiments, the laminate 200 includes a first glass, a first encapsulant film, a battery, a second encapsulant film, and a second glass stacked in sequence.

[0061] Next, the photovoltaic device according to the embodiments of the present invention will be described.

[0062] The photovoltaic device according to the embodiment of the present invention includes a frame assembly 100 for the photovoltaic device.

[0063] The photovoltaic device according to the embodiment of the present invention is provided with a frame assembly 100. The first frame 1 includes a first body portion 11, and the second frame 2 includes a second body portion 21. One end in the length direction of the first body portion 11 and one end in the length direction of the second body portion 21 form an angle with each other. The first engaging portion 111 is formed by partially cutting the first body portion 11, and the second engaging portion 211 is formed by partially cutting the second body portion 21. The first engaging portion 111 and the second engaging portion 211 are clamped to realize the direct connection between the first frame 1 and the second frame 2, and also realize the detachable connection between the first frame 1 and the second frame 2, which is convenient for the maintenance and replacement of the first frame 1 and the second frame 2, and improves the production fault tolerance rate. At the same time, without other indirect connection structures, the connection between the two can be realized through the self-structures of the first frame 1 and the second frame 2, thereby reducing the assembly process of the photovoltaic device and improving the assembly efficiency.
