[0044] Combination Figure 1 to Figure 5According to some embodiments of the present application, the embodiments of the present application provide a photovoltaic module frame and bracket assembly structure on one hand, so as to facilitate the disassembly of the photovoltaic module frame and bracket assembly structure and have high firmness. The assembly structure includes: two photovoltaic module frames 100, each photovoltaic module frame 100 includes a first part 110, a second part 120 and a third part 130 connected to each other, the first part 110 is used to carry the photovoltaic module 10, the second part 120 is used to connect the angle code, and the third part 130 is used to connect the photovoltaic bracket 200.

The assembly structure includes: a photovoltaic bracket 200, the photovoltaic bracket 200 includes a first side portion 211, a second side portion 212, a bottom support portion 213 connecting the first side portion 211 and the second side portion 212, a first clamping portion 214 extending along the end of the first side portion 211, and a second clamping portion 215 extending along the second side portion 212, the first side portion 211, the second side portion 212, the bottom support portion 213, the first clamping portion 214 and the second clamping portion 215 constitute a second cavity 216. The assembly structure includes: a pressing block 300, which is located in the second cavity 216. The pressing block 300 is used to abut the top surface of at least a portion of the length of the second connecting edge 133 against the bottom surface of the first clamping portion 214 facing the second cavity 216, or to abut the top surface of at least a portion of the length of the second connecting edge 133 against the bottom surface of the second clamping portion 215 facing the second cavity 216; wherein the overlapping length L1 of the second connecting edge 133 and the first clamping portion 214 is less than or equal to the length L3 of the second connecting edge 133 along the first direction X.

[0045] In this way, the photovoltaic component frame 100, the pressing block 300 and the photovoltaic support 200 are sequentially connected in the photovoltaic component frame and the support assembly structure, and the photovoltaic component frame 100 is fixed on the photovoltaic support 200 through the mutual cooperation between the third side 131, the first clamping portion 214 and the pressing block 300, thereby preventing the photovoltaic component frame 100 from being separated from the photovoltaic support 200, and improving the firmness of the photovoltaic component frame 100. Secondly, the overlapping length L1 of the second connecting edge 1333 and the first clamping portion 214 is less than or equal to the length L3 of the second connecting edge 133 along the first direction X.

[0046] In some embodiments, the photovoltaic module frame 100 is made of an integral metal material. The metal material can be steel, specifically including but not limited to any one of stainless steel, alloy steel or cast steel. The steel material has high toughness and can withstand impact.

[0047] In some embodiments, the corner bracket is made of an integrated metal material. The material of the photovoltaic module frame and the corner bracket can be the same, effectively avoiding potential corrosion caused by the potential difference between the photovoltaic module frame and the corner bracket. The integrated molding structure can simplify the process flow, increase production efficiency, and help improve the structural stability of the corner bracket and the photovoltaic module frame.

The first part 110 is used to carry the photovoltaic component, the second part 120 is used to connect the corner code, and the third part 130 is used to connect the photovoltaic bracket. Specifically, the first part 110 includes a first side 111 and a first bearing part 112. The second part includes: a second side 121 and a second bearing part 122. Among them, the first side 111, the first bearing part 112 and the second bearing part 122 form a semi-open first chamber 113, and the first chamber 113 is used to accommodate the photovoltaic component 10 (refer to Figure 1 ).

[0050] In some embodiments, the surface of the first supporting portion 112 away from the first chamber 113 has a first limiting structure 114, and the first limiting structure 114 is used to improve the contact performance between the limiting device and the frame of the photovoltaic component, thereby avoiding separation between the limiting device and the frame of the photovoltaic component, and further improving the firmness and safety of the photovoltaic component.

[0051] In some embodiments, the first part is also provided with a glue overflow port for glue overflow and a reinforcing rib design for improving strength. The embodiments of the present application do not describe them in detail, and those skilled in the art may refer to the relevant contents in the art regarding the glue overflow port and reinforcing ribs.

[0052] The second side edge 121, the second bearing portion 122 and the first connecting edge 132 form a semi-open second chamber 123, and the second chamber 123 is used to accommodate corner codes so that multiple photovoltaic component frames form a rectangle surrounding the photovoltaic components, so that the photovoltaic components can be placed on the photovoltaic bracket.

[0053] Among them, the specific details of the matching structure between the adhesive film and the photovoltaic module frame and the corner code are described in detail in the embodiments of this application, and those skilled in the art can refer to the relevant content about the matching structure and corner code in the art.

[0054] In some embodiments, the second portion 120 further includes a reinforcing portion 124, the two ends of which are respectively connected to the second bearing portion 122 and the first connecting edge 132, and the reinforcing portion 124 is used to increase the strength of the second chamber 123 to prevent the second chamber 123 and the photovoltaic module frame from being deformed. The reinforcing portion 124 can be connected to any area of ​​the second bearing portion 122, and the extension direction can be parallel to or intersecting with the second side edge 121.

[0056] In some embodiments, the length of the first connecting edge 132 along the first direction X is greater than the length of the second connecting edge 133 along the first direction X. Specifically, the length of the orthographic projection figure of the first connecting edge 132 on the reference surface along the first direction X is greater than the length of the orthographic projection figure of the second connecting edge 133 on the reference surface along the first direction X. More specifically, the distance S1 between the first end of the orthographic projection figure of the first connecting edge 132 on the reference surface and the first end of the orthographic projection figure of the second connecting edge 133 on the reference surface is greater than 0. The range of S1 can be 5mm to 20mm. In this way, the bottom area of ​​the photovoltaic module frame can be set shorter, thereby reducing the preparation cost and amount of the photovoltaic module frame and achieving lightweight.

[0057] The range of S1 may be 5 mm to 8 mm, 8 mm to 13 mm, 13 mm to 15 mm, 15 mm to 18 mm or 18 mm to 20 mm. S1 may be 5 mm, 6 mm, 10 mm, 12 mm, 14 mm, 17 mm, 19 mm or 20 mm.

[0059] In some embodiments, the second connecting edge 133 includes a first surface 1331 and a second surface 1332. The second surface 1332 has a second limiting structure, which is used to improve the contact performance between the pressing block and the photovoltaic component frame, thereby avoiding separation between the pressing block and the photovoltaic component frame, thereby improving the firmness and safety of the photovoltaic component.

[0060] The photovoltaic support 200 refers to a support structure that arranges photovoltaic components in a certain direction and angle and at a fixed spacing according to the specific geographical location, climate and solar energy resource conditions of the photovoltaic power generation system.

[0061] refer to Figure 4 A bending angle is formed between the first side edge portion 211 and the first locking portion 214 in the photovoltaic bracket, so that the third portion 130 of the photovoltaic component frame (the first photovoltaic component frame 11) can be locked to prevent the photovoltaic component frame from moving.

[0062] Similarly, a bending angle is formed between the second side portion 212 and the second locking portion 215 to lock the third portion 130 of another photovoltaic component frame (the second photovoltaic component frame 12 ).

[0063] refer to Figure 5In some embodiments, the pressing block 300 includes a first pressing block 310 and a second pressing block 320. The first pressing block 310 is located on the second pressing block 320. The second pressing block 320 is used to abut the top surface of the second connecting edge 133 of at least a part of its length against the bottom surface of the first clamping portion 214 facing the second cavity 216; the side surface of the first pressing block 310 abuts against the side surface of the third side 131 away from the first cavity 134. In this way, an abutting force is formed between the first pressing block 310 and the third side 131, and an abutting force can also be formed between the second pressing block 320 and the second surface 1332 of the second connecting edge 133, so that the pressing block can form two abutting forces with the frame of the photovoltaic module, thereby improving the firmness of the frame of the photovoltaic module and the photovoltaic bracket, and preventing the frame of the photovoltaic module from being separated from the photovoltaic bracket.

[0064] In some embodiments, the overlapping length of the second connection edge 133 and the first clamping portion 214 is the first length L1; the overlapping length of the first pressing block 310 and the third side 131 is the second length L2, and the length of the second connection edge 133 is the third length L3; the first length, the second length and the third length satisfy the formula: L3-2L1≥1mm and 6mm≤L2+L3≤40mm. In this way, the relationship between the second connection edge 133, the first clamping portion 214 and the first pressing block 310 can be defined so that the pressing block, the photovoltaic module frame and the photovoltaic bracket are more secure and easy to disassemble.

[0065] Specifically, setting L3-2L1≥1mm, the length of the second connecting edge 133 is greater than the overlapping length of the first pressing block 310 and the third side 131, and the overlapping area between the second connecting edge 133 and the first clamping portion is smaller, that is, part of the second connecting edge 133 is not matched with the first clamping portion 214, and part of the first clamping portion 314 is not matched with the second connecting edge 133, so that the two photovoltaic component frames corresponding to one photovoltaic component can be moved, and then only the photovoltaic component frame can be disassembled.

In this way, the overlapping length of the first pressing block 310 and the third side 131 and the length of the second connecting edge 133 are in a fixed frame, which can ensure the stability of the photovoltaic module frame itself within the limited space of the photovoltaic support, and avoid the problem that the photovoltaic module frame and the photovoltaic support cannot be disassembled or is difficult to disassemble.

[0067] The overlapping length between the second connecting edge 133 and the first locking portion 214 satisfies: 5.5mm≤L1≤15mm. The overlapping length between the first pressing block 310 and the third side 131 satisfies: 2mm≤L2≤16mm. The length of the second connecting edge 133 satisfies: 5.5mm≤L1≤15mm.

[0068] The overlapping length of the second connecting edge 133 and the first clamping portion 214 can be 5.5mm, 6.1mm, 7.5mm, 8.3mm, 9.5mm, 10.6mm, 11.5mm, 12.2mm, 13.1mm, 13.8mm or 14.5mm. The overlapping length of the first pressing block 310 and the third side 131 can be 2.2mm, 3.3mm, 4.5mm, 5.2mm, 6.5mm, 7.6mm, 8.3mm, 9.2mm, 10.5mm, 11.5mm, 12.2mm, 13.1mm, 14.8mm or 15.5mm. The length of the second connecting edge 133 can be 5.5mm, 6.5mm, 7.6mm, 8.3mm, 9.2mm, 10.5mm, 11.5mm, 12.2mm, 13.1mm, 14.8mm or 15mm.

[0069] In some embodiments, the distance L between two photovoltaic assembly frames 100 located in the same photovoltaic bracket 200 satisfies: L is greater than 15 mm, that is, the distance between the first photovoltaic assembly frame 11 and the second photovoltaic assembly frame 12 satisfies: L is greater than 15 mm. The distance L can make the distance between the adjacent first photovoltaic assembly frame 11 and the second photovoltaic assembly frame 12 larger, so that the photovoltaic assembly frames can be quickly separated to avoid interference problems.

Secondly, the overlapping length L1 of the second connecting edge 1333 and the first clamping portion 214 is less than or equal to the length L3 of the second connecting edge 133 along the first direction X.
