[0052] Embodiments of the present application are described in detail below with reference to the attached drawings, which show by way of example, embodiments in which like numerals indicate like elements or elements having the same or similar function throughout the several figures. The embodiments described below are exemplary and are not intended to limit the present application in any way.

[0053] The disclosure below provides many different embodiments or examples for implementing different structures of the present application. For the purpose of simplicity, the elements and settings of the particular examples below are described in some detail. Of course, they are merely examples and are not intended to limit the present application in any way.

Furthermore, the present application provides various examples of specific processes and materials, but one of ordinary skill in the art can realize the applicability of other processes and / or the use of other materials.

[0054] As shown in the drawings, the frame 100 according to the first aspect of the present application comprises a straight profile. The straight profile is provided with at least one cutout along its length direction, and the straight profile is bent 90° at the cutout to form the frame 100. Figures 1-27 The straight profile comprises a connecting plate 12 and at least one support plate 11. The number of the connecting plate 12 is one, and the number of the support plate 11 is one or two. The support plate 11 is connected to the connecting plate 12 on one side wall opposite to the other side wall, and the other side wall is provided with a cutout 111. The cutout 111 is formed by recessing from the other side wall to the one side wall, and the cutout 111 comprises a first cut edge 1111 and a second cut edge 1112. One end of the first cut edge 1111 is connected to one end of the second cut edge 1112, and the connection position of the two is on the one side wall opposite to the other side wall of the support plate 11.

[0055] When bent 90° at the cutout 111, the first cut edge 1111 and the second cut edge 1112 at least partially match in shape.

[0056]

[0057] ​It should be noted that, for straight profiles, the support plate 11 and the connecting plate 12 can be curved surfaces, meaning that at least one of the two surfaces of the support plate 11 is curved, and at least one of the two surfaces of the connecting plate 12 is curved, such as... Figure 1 As shown; the support plate 11 and the connecting plate 12 can be flat plates, that is, the two surfaces of the support plate 11 are flat, and the two surfaces of the connecting plate 12 are flat, as shown. Figure 2 , Figure 3 As shown.

[0058] A support plate 11 is provided, located on one side of the connecting plate 12. The support plate 11 is located on one side of the connecting plate 12 and the two are connected to each other, as shown below. Figure 3 As shown, the angle between the support plate 11 and the connecting plate 12 is 90°, and at the current moment, the cross-section of the frame 100 is L-shaped.

[0059] Of course, it is understood that the included angle between the support plate 11 and the connecting plate 12 can be 60°, 85°, 88°, 105°, 110°, etc., which will not be listed in this embodiment.

[0060] Two support plates 11 are provided, which are arranged opposite each other and located on the same side of the connecting plate 12. There can be two support plates 11. The two support plates 11 are arranged opposite each other and located on one side of the connecting plate 12, and the support plates 11 and the connecting plate 12 are connected to each other, such as... Figure 2 As shown, the angle between the support plate 11 and the connecting plate 12 is 90°, and at the current moment, the cross-section of the frame 100 is C-shaped.

[0061] Of course, it is understood that the included angle between the support plate 11 and the connecting plate 12 can be 60°, 85°, 88°, 105°, 110°, etc., which will not be listed in this embodiment.

[0062] Among them, such as Figures 4-13 As shown, when the straight profile is bent into the frame 100, the first cut edge 1111 and the second cut edge 1112 are at least partially abutted. With this configuration, the connecting plate 12 remains a single unit before and after the straight profile is bent, and its continuity is not altered, helping the frame 100 maintain good grounding continuity. When the straight profile is bent into the frame 100, the first cut edge 1111 and the second cut edge 1112 of the cut 111 are seamlessly joined, and no wrinkles appear when the first cut edge 1111 and the second cut edge 1112 are joined, thus ensuring a good appearance for the frame.

[0063] Among them, such as Figures 14-15As shown, when the straight profile is bent into the frame 100, a glue-filling gap 112 is formed between the first cut edge 1111 and the second cut edge 1112 of the cutout 111. In this way, the connecting plate 12 remains an integral whole before and after the straight profile is bent, and the continuity of the connecting plate 12 does not change, which helps to maintain good grounding continuity of the frame 100. When the photovoltaic laminate 500 overflows with glue, the overflowing glue can fill the glue-filling gap 112 between the first cut edge 1111 and the second cut edge 1112, thereby avoiding the overflowing glue from overflowing and contaminating the frame. At the same time, the glue-filling gap 112 can release the force generated during the bending process, thereby avoiding deformation of the connecting plate 12 and helping to ensure the bending angle.

[0064] It should be noted that the following embodiments are exemplified by taking the cross section of the frame 100 as C-shaped:

[0065] Optionally, the first cut edge 1111 and the second cut edge 1112 are linear.

[0066] In a first specific embodiment, the edge of the support plate 11 under the straight profile is recessed to form a cutout 111, which is an isosceles right triangle, as shown in Figure 4 At the current time, the length of the first cut edge 1111 is equal to the length of the second cut edge 1112. The frame 100 is bent by 90° at the cutout 111, and the straight profile is the frame 100, as shown in Figure 5 At the current time, the first cut edge 1111 of the cutout 111 can completely fit with the second cut edge 1112. The fitting track of the first cut edge 1111 and the second cut edge 1112 is a straight line.

[0067] In this way, the appearance of the cutout 111 is improved; at the same time, the seamless butt joint between the first cut edge 1111 and the second cut edge 1112 can improve the overall structural stability of the frame.

[0068] In a second specific embodiment, the edge of the support plate 11 under the straight profile is recessed to form a cutout 111, which is a right triangle, as shown in Figure 6 At the current time, the length of the first cut edge 1111 is greater than the length of the second cut edge 1112. The frame 100 is bent by 90° at the cutout 111, and the straight profile is the frame 100, as shown in Figure 7 At the current time, the first cut edge 1111 of the cutout 111 is partially fitted with the second cut edge 1112. The fitting track of the first cut edge 1111 and the second cut edge 1112 is a straight line.

[0069] In a third specific embodiment, the edge of the support plate 11 under the straight profile is recessed to form a cutout 111, which is a pentagon, as shown in Figure 8As shown. At the current moment, the length of the first cut edge 1111 is equal to the length of the second cut edge 1112. The frame 100 is bent 90° at the cut 111, and the straight profile is the frame 100, as shown. Figure 9 As shown, at the current moment, a portion of the first cutting edge 1111 of the cut 111 is in contact with a portion of the second cutting edge 1112. The contact trajectory of the first cutting edge 1111 and the second cutting edge 1112 is a straight line.

[0070] Optionally, the first cutting edge 1111 and the second cutting edge 1112 are in the shape of broken lines.

[0071] In the fourth specific embodiment, the edge of the support plate 11 under the straight profile is recessed to form a cut 111, which is hexagonal, such as... Figure 10 As shown. At the current moment, the length of the first cut edge 1111 and the length of the second cut edge 1112 are equal. The frame 100 is bent 90° at the cut 111, and the straight profile is the frame 100, as shown. Figure 11 As shown, at the current moment, the first cutting edge 1111 and the second cutting edge 1112 of the cut 111 can fit together completely. The fitting trajectory of the first cutting edge 1111 and the second cutting edge 1112 is a broken line.

[0072] This design improves the aesthetic appearance of the cut 111; at the same time, the seamless connection between the first cut edge 1111 and the second cut edge 1112 can improve the overall structural stability of the frame.

[0073] It should be noted that the bonding trajectory of the first cut edge 1111 and the second cut edge 1112 is as follows: Figure 11 Besides the polyline shown, other polylines can also be used, and those skilled in the art can design them according to the actual situation.

[0074] Optionally, the first cutting edge 1111 and the second cutting edge 1112 are curved.

[0075] In the fifth specific embodiment, the edge of the support plate 11 under the straight profile is recessed to form a cut 111, the cut 111 as follows: Figure 12 As shown. At the current moment, the length of the first cut edge 1111 and the length of the second cut edge 1112 are equal. The frame 100 is bent 90° at the cut 111, and the straight profile is the frame 100, as shown. Figure 13 As shown, at the current moment, the first cutting edge 1111 and the second cutting edge 1112 of the cut 111 can fit together completely. The fitting trajectory of the first cutting edge 1111 and the second cutting edge 1112 is a curve.

[0076] This design improves the aesthetic appearance of the cut 111; at the same time, the seamless connection between the first cut edge 1111 and the second cut edge 1112 can improve the overall structural stability of the frame.

[0077] It should be noted that the shapes of the first cut edge 1111 and the second cut edge 1112 are Figure 13 In addition to the curved lines shown in the figure, other curves can also be used, which can be designed by the skilled person in the art according to the actual situation.

[0078] Optionally, the glue-filling gap 112 is an equal-size gap.

[0079] In the sixth specific embodiment, a cutout 111 is formed by recessing the edge of the support plate 11 under the straight profile, the edge is opposite to the edge of the support plate 11 connected to the connecting plate 12, and the cutout 111 is an isosceles trapezoid, as shown in the figure. At the current time, the length of the first cut edge 1111 is equal to the length of the second cut edge 1112. The frame 100 is bent by 90° at the cutout 111, and the straight profile is the frame 100, as shown in the figure. At the current time, the first cut edge 1111 of the cutout 111 is parallel to the second cut edge 1112, and the two form an equal-size glue-filling gap 112. Figure 14 Figure 15

[0080] In this way, the glue-filling gap 112 is easy to process, and the appearance of the glue-filling gap 112 is also improved.

[0081] Of course, it can be understood that the cutout 111 can also be a right trapezoid. The cutout 111 can also be other shapes, so that the glue-filling gap 112 is a curved equal-size gap. At the same time, the cutout 111 can also be a rectangle or other suitable shape, so that the glue-filling gap 112 is a non-equal-size gap.

[0082] In the sixth specific embodiment, the cutout 111 in the isosceles trapezoid includes an upper base, a lower base, and a first cut edge 1111 and a second cut edge 1112 between the upper base and the lower base. The length of the upper base is c, and 1mm≤c≤2mm. The length of the lower base is e, and c

[0083] In addition, as shown in the figure Figure 16 ​​As shown, the connecting plate 12 is smoothly transitioned at the position corresponding to the glue-filling gap 112. The radius of the arc at the position corresponding to the glue-filling gap 112 of the connecting plate 12 is R1, t≤R1≤6t, and the thickness of the connecting plate 12 is t. R1 is the outer diameter of the arc transition, R1-t=R2, and R2 is the inner diameter of the arc transition. Thus, 0≤R2≤5t. In actual production, the creepage distance K needs to be greater than or equal to 13, and the greater the radius R1 / R2 means that the more white space positions P of the glass, which will lead to a lower area ratio on the battery assembly. Based on this, the embodiment limits t≤R1≤6t and 0≤R2≤5t to reduce the white space position P and improve the utilization rate of the battery assembly.

[0084] According to some embodiments of the present application, the linear profile is made of sheet metal profile.

[0085] The sheet metal profile is a thin plate. In actual application, the thin plate is an aluminum-zinc-magnesium alloy plate, and the thin plate is first punched by the punching process to form the above-mentioned notch 111. Then, the thin plate with the notch 111 is formed into a linear profile through the first bending process, and at the current time, the cross section of the linear profile can be C-shaped, L-shaped, etc. Then, the linear profile is further bent by 90° along the notch 111 to form the frame.

[0086] In this way, the frame is designed in an integrated manner, improving the processing efficiency of the sheet metal profile and reducing the processing cost of the linear profile.

[0087] According to some embodiments of the present application, the linear profile can be sequentially and spacedly arranged with N notches 111 along the length direction thereof, and N is one of 4, 3, 2 and 1.

[0088] In actual application, the frame 100 can be L-shaped, i.e., the linear profile is provided with one notch 111; the frame 100 can be C-shaped, i.e., the linear profile is provided with two notches 111; the frame 100 can be a rectangular frame lacking one corner, i.e., the linear profile is provided with three notches 111; or the frame 100 can be a complete rectangular frame, or a rectangular frame lacking a partial short side or a partial long side, i.e., the linear profile is provided with four notches 111.

[0089] The photovoltaic module includes a photovoltaic laminate 500 and a frame assembly for mounting the photovoltaic laminate 500, and the frame assembly includes the above-mentioned frame. The length of the short side of the photovoltaic module is defined as a, and the unit of a is mm. The length of the long side of the photovoltaic module is defined as b, and the unit of b is mm.

The distance from one end of the first frame 101 to the first cutout 111a is L1, and the distance from the other end of the first frame 101 to the second cutout 111b is L2, L1=L2, and L2<1 / 2b.

[0091] As shown in the figure, Figure 17 two first frames 101 are oppositely and spacedly arranged, and the opposite ends of the two first frames 101 are connected by a first straight frame 200, so that the two first frames 101 and the first straight frame 200 form a frame assembly. Among them, the cross-sectional structure of the first straight frame 200 is the same as that of the first frame 101.

[0092] The two first frames 101 are symmetrically arranged about the width direction center line A of the frame assembly. Among them, the ends of the first frame 101 and the ends of the first straight frame 200 are connected by welding, as shown in the figure, Figure 17 and Figure 27 The length of the first straight frame 200 is d1, and 400mm≤d1≤0.9b. Preferably, d1=0.72b.

[0093] As shown in the figure, Figure 18 welding position can be provided with an aluminum edge 400 to cover the welding seam to shield the welding seam position and improve the overall aesthetics of the frame. In addition, the two symmetrically arranged first frames 101 can facilitate the assembly of the frame, and at the same time, the welding seam of the frame is located on the long side of the frame, and the welding seam is a straight welding seam, which is convenient for welding and helps to ensure the welding quality.

[0096] As shown in the figure, Figure 19As shown, two second frames 102 are oppositely and spacedly arranged, and the oppositely arranged ends of the two second frames 102 are connected by a second straight frame 300, so that the two second frames 102 and the second straight frame 300 form a frame assembly. The cross-sectional structure of the second straight frame 300 is the same as that of the second frame 102.

[0097] The two second frames 102 are symmetrically arranged about the length direction center line B of the frame assembly. The ends of the second frame 102 and the ends of the second connecting beam 300 are connected by welding, as shown. Figure 19 The length of the second straight frame 300 is d2, and 400mm≤d2≤0.9a. Preferably, d2=0.72a.

[0098] Alternatively, as shown, the third frame 103 is C-shaped, and a first cutout 111a and a second cutout 111b are arranged thereon, and the distance between the first cutout 111a and the second cutout 111b is a. The distance from one end of the third frame 103 to the first cutout 111a is L5, and the distance from the other end of the third frame 103 to the second cutout 111b is L6, L5+L6=b, L5<b, and L6<b.
