The installation module 100 and the support module 200 are arranged along a first direction and are connected to each other. The installation module 100 has a receiving groove 110 for accommodating solar cells. A limiting protrusion 130 is provided on the groove wall of the receiving groove 110. The limiting protrusion 130 is used to limit the outflow of glue in the receiving groove 110; the first compression rivet 120 passes through the installation module 100 and extends into the receiving groove 110; the bending module 300 and the support module 200 are arranged along a second direction, wherein the first direction is perpendicular to the second direction. The bending module 300 includes at least one layer of panel structure, one end of the bending module 300 is connected to the support module 200, and the other end is bent to form a six-layer structure 310.

[0038] The above-mentioned photovoltaic system steel frame assembly arranges and connects the mounting module 100 and the support module 200 along a first direction, and arranges and connects the bending module 300 and the support module 200 along a second direction. A limiting protrusion 130 is provided in the receiving groove 110 of the mounting module 100 to prevent the glue in the receiving groove 110 from overflowing. In addition, a first compression rivet 120 is provided through the mounting module 100, and the end of the first compression rivet 120 extends into the receiving groove 110, thereby structurally strengthening the mounting module 100 and enhancing the structural strength of the mounting module 100. In addition, the end of the bending module 300 facing away from the support module 200 is bent to form a six-layer structure 310, further strengthening the structural strength of the bending module 300, thereby strengthening the structural strength of the photovoltaic system steel frame assembly and improving the load-bearing capacity of the photovoltaic system steel frame assembly.

[0039] Specifically, if Figures 1 to 4 As shown, the bending module 300 is disposed at one end of the supporting module 200 away from the mounting module 100 , and the bending module 300 and the supporting module 200 are arranged along the second direction.

[0040] Specifically, the mounting module 100 , the supporting module 200 and the bending module 300 are integrally formed.

[0041] Furthermore, if Figures 1 to 4 As shown, the mounting module 100 includes a first section 140 and a second section 150 connected to each other. The first section 140 is connected to the support module 200, and the second section 150 is arranged on a side of the first section 140 facing away from the support module 200. The first section 140, the second section 150, and the support module 200 enclose a receiving groove 110. The first section 140 of the mounting module 100 is connected to the support module 200, and the second section 150 is arranged on a side of the first section 140 facing away from the support module 200 and connected to the first section 140. The first section 140, the second section 150, and the support module 200 enclose a receiving groove 110 to facilitate the installation of battery cells.

[0042] Specifically, if Figures 1 to 4 As shown, the mounting module 100 has a double-layer panel structure. A first compression rivet 120 is provided on the first section 140. The first compression rivet 120 is used to ensure direct contact between the two panels of the first section 140. A limiting protrusion 130 is provided on the panel structure of the second section 150 on the side closest to the support module 200. By providing the first compression rivet 120 on the first section 140, the two panels of the first section 140 are in direct contact, thereby improving the structural strength of the mounting module 100. Furthermore, the limiting protrusion 130 is provided on the panel structure of the second section 150 on the side closest to the support module 200, that is, on the inner panel of the second section 150, to prevent glue overflow from the receiving slot 110.

[0043] In some embodiments, as Figures 1 to 3 As shown, the second section 150 includes a straight plate-shaped, connected first connecting portion 151 and a second connecting portion 152. The first connecting portion 151 is connected to the first section 140 and is parallel to the support module 200. The angle between the first connecting portion 151 and the second connecting portion 152 is an obtuse angle. The second connecting portion 152 is provided with a limiting protrusion 130. The second section 150 is configured as a straight plate. The second section 150 includes a first connecting portion 151 and a second connecting portion 152 that are connected. The angle between the first connecting portion 151 and the second connecting portion 152 is an obtuse angle. The second connecting portion 152 is provided with a limiting protrusion 130.

[0044] In some embodiments, as Figure 4 As shown, the second segment 150 is arc-shaped.

[0045] Furthermore, if Figure 3 As shown, the support module 200 has a cavity 210, and a reinforcement member 220 is provided on the cavity wall of the cavity 210. The reinforcement member 220 is used to enhance the structural strength of the support module 200. The reinforcement member 220 is provided on the cavity wall of the support module 200 to enhance the structural strength of the support module 200, thereby increasing the structural strength and load-bearing capacity of the photovoltaic system steel frame assembly.

[0046] Specifically, if Figure 3 As shown, the support module 200 is a single-layer panel structure. When the cavity 210 is formed, the single-layer panel is folded 180° to form a two-layer structure, thereby forming a reinforcement member 220.

[0047] Furthermore, in some embodiments, Figure 5 As shown, the bending module 300 has a double-layer panel structure. The end of the bending module 300, facing away from the support module 200, is simultaneously folded twice in the same direction, each folding 180°, to form a six-layer structure 310. The bending module 300 has a double-layer panel structure. The double-layer panel at the end of the bending module 300 is first folded 180° and then folded again 180° in the same direction to form the six-layer structure 310.

[0048] Furthermore, in some embodiments, Figure 6 and Figure 7 As shown, the bending module 300 has a double-layer panel structure, including a first panel and a second panel. The first panel is disposed above the second panel, and the second panel is configured to bend and fold twice toward the first panel, each folding 180°, to form a four-layer structure 320. The four-layer structure 320 is folded to form a six-layer structure 310. The bending module 300 has a double-layer panel structure. First, the second panel of the bending module 300 is folded 180°. Then, the second panel of the two-layer structure is folded 180° again to wrap around the first panel, thereby forming the four-layer structure 320. Finally, the four-layer structure 320 is folded as a whole to form the six-layer structure 310.

[0049] It should be noted that there are many specific folding methods for the six-layer structure 310 , and this application only uses two conventional folding methods as examples.

[0050] Furthermore, the bending module 300 further includes a second compression rivet, which is configured to penetrate the six-layer structure 310. Penetrating the second compression rivet through the six-layer structure 310 enhances the connection performance between the panels of the six-layer structure 310 and further enhances the structural strength of the six-layer structure 310.

[0051] Specifically, the first pressure rivet 120 and the second pressure rivet in the present application are rivets.

[0052] More specifically, a plurality of first compression rivets 120 and a plurality of second compression rivets are provided and arranged along the length direction of the photovoltaic system steel frame assembly.

[0053] Furthermore, in other embodiments, the panels of the six-layer structure 310 may be welded to each other to increase the structural strength of the six-layer structure 310. The specific welding positions are selected according to the actual operation.

[0054] Furthermore, in other embodiments, the bending module 300 includes a first region and a second region, the first region being connected to the support module 200, and the second region being bent relative to the first region at a preset angle, wherein the preset angle is less than or equal to 90°, and the second region includes a six-layer structure 310. Folding the second region of the bending module 300 relative to the first region, i.e., folding the six-layer structure 310 at the preset angle, further enhances the structural strength of the photovoltaic system's steel frame assembly.

[0055] Specifically, the preset angle range of the bending of the second area is: 0°<preset angle≤90°, for example, the preset angle is 10°, 20°, 30°, 40°, 50°, 60°, 70°, 80°, 90°.

[0056] The present application also provides a photovoltaic system, comprising a cell and the aforementioned photovoltaic system steel frame assembly, wherein the cell is disposed within a receiving groove 110. The cell is disposed within the receiving groove 110 and secured with glue, and a limiting protrusion 130 is provided on the wall of the receiving groove 110 to prevent the glue within the receiving groove 110 from overflowing. Furthermore, a first compression rivet 120 is provided that penetrates the mounting module 100, and the end of the first compression rivet 120 extends into the receiving groove 110. Furthermore, the end of the bending module 300 facing away from the support module 200 is bent to form a six-layer structure 310, thereby enhancing the structural strength and load-bearing capacity of the photovoltaic system.

[0057] Specifically, the photovoltaic system steel frame assembly includes a long frame and a short frame, which are connected by connecting angle brackets 400. It should be noted that the long frame and the short frame have the same structure, but different lengths.

[0058] Specifically, the connecting angle bracket 400 includes an aluminum angle bracket and a steel angle bracket. The pull-off force of the connecting angle bracket 400 affects the bearing capacity of the entire component frame. In order to strengthen the pull-off force of the connecting angle bracket 400, for the aluminum angle bracket solution, Figure 1 and Figure 8 As shown, this application utilizes six-point riveting on the photovoltaic system steel frame assembly (four-point riveting can also be used in other embodiments), and also provides a third riveting member on the connecting angle bracket 400. The riveting position is located on the reinforcing rib of the connecting angle bracket 400, and the rivet points are then clamped by serrations, greatly enhancing the pull-out force. For the steel angle bracket solution, two narrow waist holes are required near the ends of the photovoltaic system steel frame assembly. After the steel angle bracket is inserted, the two elastic clamping points are locked into the waist holes, and the pull-out force is more than times that of a normal aluminum angle bracket.

[0059] It should be noted that the connection angle bracket 400 generally uses an aluminum alloy angle bracket, and a steel angle bracket can also be used, with slight differences in the fastening methods.

[0060] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0061] The above embodiments merely illustrate several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
