In addition, the utility model provides various specific examples of processes and materials, but those of ordinary skill in the art can be aware of the applicability of other processes and / or the use of other materials.

[0062] like Figure 1-Figure 30 As shown, the frame profile 100 according to the first aspect of the present invention comprises: a connecting plate 12 and at least one supporting plate 11. The number of the connecting plate 12 is one, and the number of the supporting plates 11 is one or two.

[0063] The support plate 11 is connected to the end of the connecting plate 12, and at least one cutout 111 is formed on the edge of the support plate 11, and the cutout 111 extends from the edge to the connection between the support plate 11 and the connecting plate 12. The cutout 111 includes a first edge 1111 and a second edge 1112, and the first edge 1111 is connected to the second edge 1112, and the connection position of the two is located on the surface of the connecting plate 12 facing the support plate 11.

[0064] When the frame profile 100 is bent 90° along the cutout 111 , the first edge 1111 and the second edge 1112 are at least partially in contact with each other.

[0065] It should be noted that the frame profile 100 has a bent state and a straight state.

[0066] When the frame profile 100 is in a straight state, the support plate 11 and the connecting plate 12 can be flat plates, that is, at least one of the two surfaces of the support plate 11 is a flat surface, and at least one of the two surfaces of the connecting plate 12 is a flat surface. Figure 1 As shown, the support plate 11 and the connecting plate 12 can be plane plates, that is, the support plate 11 has two surfaces: a first upper surface 1101 and a first lower surface 1102, both of which are planes, and the connecting plate 12 has two surfaces: both of which are planes. Among them, the support plate 11 and the connecting plate 12 can be perpendicular to each other. Of course, it can be understood that the angle between the support plate 11 and the connecting plate 12 can be 60°, 85°, 88°, 105°, 110°, ..., which are not listed one by one in this embodiment.

[0067] The support plate 11 and the connection plate 12 may be curved plates, that is, at least one of the two surfaces of the support plate 11 is a curved surface, and at least one of the two surfaces of the connection plate 12 is a curved surface.

[0068] Of course, one of the support plate 11 and the connecting plate 12 is a curved plate, and the other is a flat plate. Figure 2 As shown, the support plate 11 may be a curved plate, and the connecting plate 12 may be a flat plate, that is, the support plate 11 has two surfaces: a second upper surface 1103 and a second lower surface 1104, both of which are curved surfaces, and the connecting plate 12 has two surfaces: both of which are flat surfaces.

[0069] When a supporting plate 11 is provided, the supporting plate 11 is located on one side of the connecting plate 12 .

[0070] The support plate 11 is located on one side of the connecting plate 12 and the two are connected to each other. Figure 3 As shown, the angle between the support plate 11 and the connecting plate 12 is 90°. At the current moment, the cross section of the frame profile 100 is L-shaped.

[0071] Of course, it is understandable that the angle between the support plate 11 and the connecting plate 12 can be 60°, 85°, 88°, 105°, 110°, ..., which are not listed one by one in this embodiment.

[0072] When two support plates 11 are provided, the two support plates 11 are disposed opposite to each other and are located on the same side of the connecting plate 12 .

[0073] There can be two support plates 11. The two support plates 11 are arranged opposite to each other and are located on one side of the connecting plate 12. The support plates 11 and the connecting plates 12 are connected to each other. Figure 2 As shown, the angle between the support plate 11 and the connecting plate 12 is 90°. At the current moment, the cross section of the frame profile 100 is C-shaped.

[0074] Of course, it is understandable that the angle between the support plate 11 and the connecting plate 12 can be 60°, 85°, 88°, 105°, 110°, ..., which are not listed one by one in this embodiment.

[0075] When the frame profile 100 switches from a straight state to a bent state, the edge of the support plate 11 is recessed to form a cutout 111, which is arranged opposite to the edge at which the support plate 11 is connected to the connecting plate 12. The frame profile 100 is bent 90° at the cutout 111 to make the frame profile 100 in a bent state. At the current moment, the first side 1111 and the second side 1112 of the cutout 111 are at least partially in contact with each other.

[0076] With this arrangement, when the frame profile 100 is in a straight state, the connecting plate 12 is an integral body, and when the frame profile 100 is in a bent state, the connecting plate 12 is still an integral body, and the grounding continuity of the frame profile 100 in the bent state does not change, which helps the frame to maintain good grounding continuity. When the frame profile 100 is in a bent state, the first side 1111 and the second side 1112 of the cutout 111 can be seamlessly butted, and no wrinkles will appear when the first side 1111 and the second side 1112 are butted, so that the frame can have a good appearance.

[0077] It should be noted that the following embodiments are described by taking the cross section of the frame profile 100 as a C-shape.

[0078] Optionally, the first side 1111 and the second side 1112 are in the shape of straight lines.

[0079] In a specific embodiment, when the frame profile 100 is in a straight state, a notch 111 is formed by a depression at the edge of the support plate 11. The edge is arranged opposite to the edge where the support plate 11 and the connecting plate 12 are connected. The notch 111 is a right-angled isosceles triangle. Figure 4 At this moment, the length of the first side 1111 is equal to the length of the second side 1112. The frame profile 100 is bent 90° at the cutout 111 so that the frame profile 100 is in a bent state, as shown in FIG. Figure 5 As shown, at the current moment, the first side 1111 of the cutout 111 can be completely fitted with the second side 1112. The fitting track of the first side 1111 and the second side 1112 is a straight line.

[0080] Such a configuration improves the aesthetic appearance of the cutout 111 ; at the same time, the seamless connection between the first side 1111 and the second side 1112 can improve the overall structural stability of the frame.

[0081] In another specific embodiment, when the frame profile 100 is in a straight state, a notch 111 is formed by a depression at the edge of the support plate 11. The edge is arranged opposite to the edge where the support plate 11 and the connecting plate 12 are connected. The notch 111 is a right triangle. Figure 6 At this moment, the length of the first side 1111 is greater than the length of the second side 1112. The frame profile 100 is bent 90° at the cutout 111 so that the frame profile 100 is in a bent state, as shown in FIG. Figure 7 As shown, at the current moment, a portion of the first side 1111 of the cutout 111 is aligned with the second side 1112. The alignment track of the first side 1111 and the second side 1112 is a straight line.

[0082] In another specific embodiment, when the frame profile 100 is in a straight state, a cutout 111 is formed at the edge of the support plate 11. The edge is arranged opposite to the edge where the support plate 11 and the connecting plate 12 are connected. The cutout 111 is a pentagon. Figure 8 At this moment, the length of the first side 1111 is equal to the length of the second side 1112. The frame profile 100 is bent 90° at the cutout 111 so that the frame profile 100 is in a bent state, as shown in FIG. Fig. 9 As shown, at the current moment, a portion of the first side 1111 of the cutout 111 is aligned with a portion of the second side 1112. The alignment track of the first side 1111 and the second side 1112 is a straight line.

[0083] Optionally, the first side 1111 and the second side 1112 are in the shape of a broken line.

[0084] In a specific embodiment, when the frame profile 100 is in a straight state, a cutout 111 is formed at the edge of the support plate 11, and the edge is arranged opposite to the edge where the support plate 11 and the connecting plate 12 are connected. The cutout 111 is a hexagon. Fig.10 At this moment, the length of the first side 1111 is equal to the length of the second side 1112. The frame profile 100 is bent 90° at the cutout 111 so that the frame profile 100 is in a bent state, as shown in FIG. Fig.11 As shown, at the current moment, the first side 1111 and the second side 1112 of the cutout 111 can be completely fitted together. The fitting track of the first side 1111 and the second side 1112 is a broken line.

[0085] Such a configuration improves the aesthetic appearance of the cutout 111 ; at the same time, the seamless connection between the first side 1111 and the second side 1112 can improve the overall structural stability of the frame.

[0086] It should be noted that the fitting trajectory of the first edge 1111 and the second edge 1112 is Fig.11 In addition to the broken lines shown in , other broken lines can also be used, and those skilled in the art can design them according to actual conditions.

[0087] Optionally, the first side 1111 and the second side 1112 are in the shape of curves.

[0088] In a specific embodiment, when the frame profile 100 is in a straight state, a notch 111 is formed at the edge of the support plate 11. The edge is arranged opposite to the edge where the support plate 11 and the connecting plate 12 are connected. Fig.12 At this moment, the length of the first side 1111 is equal to the length of the second side 1112. The frame profile 100 is bent 90° at the cutout 111 so that the frame profile 100 is in a bent state, as shown in FIG. Fig.13As shown, at the current moment, the first side 1111 of the cutout 111 can be completely fitted with the second side 1112. The fitting track of the first side 1111 and the second side 1112 is a curve.

[0089] Such a configuration improves the aesthetic appearance of the cutout 111 ; at the same time, the seamless connection between the first side 1111 and the second side 1112 can improve the overall structural stability of the frame.

[0090] It should be noted that the shapes of the first side 1111 and the second side 1112 are Fig.13 In addition to the curve shown in , other curves can also be used, and those skilled in the art can design them according to actual conditions.

[0091] According to some embodiments of the present invention, the frame profile 100 is a sheet metal frame profile. The "sheet metal" here refers to the sheet metal in the sheet metal process, which is a comprehensive cold processing process for metal sheets (usually less than 6 mm), including shearing, punching / cutting / combining, folding, welding, riveting, splicing, forming, etc.

[0092] The sheet metal plate with the cutout 111 is formed into a sheet metal frame profile in a straight state through a first bending process, and the sheet metal plate is further bent 90° along the cutout 111 to form a sheet metal frame profile in a bent state. In practical applications, the sheet metal plate is an aluminum-zinc-magnesium alloy plate, and the sheet metal plate is first punched out of the cutout 111 through a punching process. Then, the sheet metal plate with the cutout 111 is formed into a sheet metal frame profile in a straight state through a first bending process, and at this moment, the cross-section of the sheet metal frame profile can be C-shaped, L-shaped, etc. Next, the sheet metal plate is further bent 90° along the cutout 111 to form a sheet metal frame profile in a bent state.

[0093] In this way, the frame can be designed as an integrated whole, which improves the processing efficiency of the sheet metal frame profile and reduces the processing cost of the sheet metal frame profile.

[0094] According to some embodiments of the present invention, N cutouts 111 may be sequentially and spaced apart on the support plate 11 along the length direction of the frame profile 100 , where N is one of 4, 3, 2, and 1.

[0095] In practical applications, the frame includes a frame profile 100 in a bent state. The frame profile 100 in a bent state may be L-shaped, that is, a straight frame profile 100 is provided with a cutout 111; the frame profile 100 in a bent state may be C-shaped, that is, a straight frame profile 100 is provided with two cutouts 111; the frame profile 100 in a bent state may be roughly C-shaped, that is, a straight frame profile 100 is provided with two cutouts 111; the frame profile 100 in a bent state may be a rectangular frame lacking one corner, that is, a straight frame profile 100 is provided with three cutouts 111; the frame profile 100 in a bent state may be a complete rectangular frame, or a rectangular frame lacking a partial short side or a partial long side, that is, a straight frame profile 100 is provided with four cutouts 111.

[0097] Alternatively, if Fig.14 As shown, the support plate 11 of the first frame profile 101 is arranged with a first cutout 111a and a second cutout 111b in sequence along the length direction of the first frame profile 101, and the distance between the first cutout 111a and the second cutout 111b is a, which is the short side length of the photovoltaic module. The distance from one end of the support plate 11 to the first cutout 111a is L1, and the distance from the other end of the support plate 11 to the second cutout 111b is L2, L1=L2, L2<1 / 2b.

Each first frame profile 101 has two cutouts, and the two ends of the first frame profile 101 are connected to one end of the two first straight frames 200 respectively.

In this way, the gap between the two welds can be opened to avoid the welding stress at the two welds affecting the straightness of the first straight frame 200, thereby helping to ensure that the frame composed of the first frame profile 101 and the first straight frame 200 is a regular rectangle. Preferably, d1=0.72b.

[0100] like Fig.15 and Fig.21 As shown, an aluminum edging 400 can be provided at the welding position to cover the weld to cover the weld position and improve the overall aesthetics of the frame. In addition, the two symmetrically arranged first frame profiles 101 can facilitate the assembly of the frame. At the same time, the weld of the frame is located on the long side of the frame, and the weld is a straight weld, which is convenient for welding and helps to ensure the welding quality.

[0101] Alternatively, if Fig.16 As shown, the support plate 11 of the second frame profile 102 is sequentially arranged with a first cutout 111a and a second cutout 111b in a spaced order along the length direction of the second frame profile 102, and the distance between the first cutout 111a and the second cutout 111b is b, which is the length of the long side of the photovoltaic module.
