[0020] <Overall Structure>

[0021] This utility model provides a novel corner bracket 100 for a photovoltaic frame, which can be spliced ​​with a long frame 200 and a short frame 300 in the form of a photovoltaic frame using the slot space described later, to form two adjacent frames surrounding a rectangular photovoltaic panel. Then, by forming two other adjacent frames on opposite sides, a rectangular photovoltaic panel assembly can be finally spliced ​​together.

[0022] In some embodiments, the following settings may be preferably adopted, such as Figures 1 to 3 As shown.

[0023] Interference wall I 101 and interference wall II 103 are parallel to each other. Interference wall III 107 and interference wall IV 109 are parallel to each other. Interference wall I 101 and interference wall III 107 are perpendicular to each other. Interference wall II 103 and interference wall IV 109 are perpendicular to each other.

[0024] One side of the locking tooth I102 is perpendicular to the interference face wall I101, and the other side forms a 45° angle with the interference face wall I101. One side of the locking tooth II104 is perpendicular to the interference face wall II103, and the other side forms a 45° angle with the interference face wall II103. One side of the locking tooth III108 is perpendicular to the interference face wall III107, and the other side forms a 45° angle with the interference face wall III107. One side of the locking tooth IV110 is perpendicular to the interference face wall IV109, and the other side forms a 45° angle with the interference face wall IV109.

[0025] Support wall I 106 is parallel to interference wall I 101. Support wall II 112 is parallel to interference wall III 107. Support wall I 106 is perpendicular to support wall II 112.

[0026] Reinforcing vertical bar I105 is perpendicular to supporting wall I106. Reinforcing vertical bar II116 is perpendicular to supporting wall II112. Reinforcing diagonal bar I113 is at a 45° angle to supporting wall II112.

[0027] The various interference-fitting walls, supporting walls, reinforcing vertical ribs, and reinforcing diagonal ribs together form a multi-cavity structure 111.

[0028] The purpose of ramp structure I 114 is to facilitate the insertion of corner bracket 100 into the long border 200 or the short border 300. The purpose of ramp structure II 115 is to facilitate the insertion of the long border 200 or the short border 300 into the gap between the corresponding interference surfaces, i.e., the slot space.

[0029] The upper wall I201 and lower wall I202 of the long frame 200 are parallel to each other, and the cavity I203 is located between the upper wall I201 and lower wall I202. The upper wall II301 and lower wall II302 of the short frame 300 are parallel to each other, and the cavity II303 is located between the upper wall II301 and lower wall II302.

[0030] Interference point I 117, interference point II 118, interference point III 204 and interference point IV 304 are small indentations stamped by a punch with a protruding small cylinder.

[0031] As illustrated above, this utility model provides a novel corner bracket 100 for a photovoltaic frame, comprising: a base structure (preferably a multi-cavity structure 111) with a cross-section generally L-shaped and having two intersecting inner sidewalls, namely interference wall II 103 and interference wall IV 109; interference wall I 101 and interference wall III 107 extending parallel to interference wall II 103 and interference wall IV 109 respectively to form a slot space for inserting a photovoltaic frame; wherein, the corresponding (or adjacent) ends of interference wall I 101 and interference wall III 107 are connected to the intersection point 120, and the corresponding (or adjacent) ends of interference wall II 103 and interference wall IV 109 are also connected to the intersection point 120.

[0032] The multi-cavity structure 111 further includes: a support wall I 106 extending parallel (preferably parallel) to the interference wall II 103 via reinforcing rib I 105, and a support wall II 112 extending parallel (preferably parallel) to the interference wall IV 109 via reinforcing rib II 116, with reinforcing diagonal ribs I 113 connecting the support wall I 106 and the support wall II 112 at their intersection and crossroads 120. These mutually spaced reinforcing ribs I 105, reinforcing rib II 116, and reinforcing diagonal ribs I 113 divide the interior of the multi-cavity structure 111, i.e., between the interference wall II 103 and the support wall I 106, and between the interference wall IV 109 and the support wall II 112, into multiple cavities.

[0033] Preferably, the corresponding ends of interference wall II 103 and interference wall I 101, and the corresponding ends of interference wall IV 109 and interference wall III 107 are connected via the bottom of the tank I 122 and the bottom of the tank II 121, respectively.

[0034] The intersection point 120 described above is not limited to the point position in the sense of multiple line segments intersecting as shown in the figure, but can also be formed as follows: Figure 1 The hollow portion enclosed by the dotted lines 123 is replaced with a rectangular intersection of solid portions. These portions that essentially constitute an intersection are collectively referred to as intersection points.

[0035] Furthermore, the two intersecting inner walls of the aforementioned L-shaped structure, namely interference wall II 103 and interference wall IV 109, are not limited to direct intersection or connection; they also include spatial intersections, for example... Figure 1 As shown, one end of the interference wall II 103 terminates at the bottom of the groove I 122 and does not directly intersect or connect with the interference wall IV 109 that terminates at the bottom of the groove II 121. Instead, they are indirectly connected via the bottom of the groove I 122 and the bottom of the groove II 121, but they still form an intersecting relationship in space.

[0036] On the opposing inner walls of interference-fit walls II 103 and I 101, and on the opposing inner walls of interference-fit walls IV 109 and III 107, respective locking teeth (locking teeth II 104, I 102, IV 110, and III 108) are formed. Each interference-fit wall, as the name suggests, has at least one of these walls having a gap or interference point structure that allows for an interference fit, either on its own or with the opposing interference-fit wall, such as interference point I 117 and interference point II 118, thereby reliably fixing the corresponding photovoltaic frame. At this time, each corresponding photovoltaic frame may also have an interference point structure that interacts with the corresponding locking teeth, such as interference point III 204 and interference point IV 304.

[0037] In addition, at least one of the matrix structure, interference wall I101, and interference wall III107 has a corresponding ramp structure (corresponding to ramp structure I114 or ramp structure II115) formed on the free end side.

[0038] <Example>

[0039] Dimensions: The dimensions of interference wall I 101, interference wall II 103, interference wall III 107 and interference wall IV 109 are the same, with a wall thickness of 1.8 (±0.15) mm and a width of 30 (±0.5) mm.

[0040] The dimensions of the locking teeth I102, II104, III108 and IV110 are the same, with a height of 0.8 (±0.1) mm.

[0041] Support wall I106 has the same dimensions as support wall II112, with a wall thickness of 1.5 (±0.15) mm and a width of 30 (±0.5) mm.

[0042] The dimensions of the reinforcing ribs I105 and II116 are the same, with a wall thickness of 2 (±0.15) mm and a height of 10 (±0.5) mm.

[0043] The wall thickness of the reinforcing diagonal rib I113 is 1.8 (±0.15) mm, and the width is 14.14 (±0.15) mm.

[0044] The upper wall I201, lower wall I202, upper wall II301 and lower wall II302 have the same dimensions and a thickness of 1.8 (±0.15) mm.

[0045] The distance between the cavity I203 of the upper wall I201 and the lower wall I202 is 14.1 (±0.1) mm.

[0046] The distance between the cavity II303 of the upper wall II301 and the lower wall II302 is 14.1 (±0.1) mm.

[0047] Interference points I117, II118, III204, and IV304 have a depth of 0.8-1 mm and a diameter of 0.6-0.8 mm.

[0048] Material, processing, and assembly specifications: Corner bracket 100, long frame 200, and short frame 300 are made of 6063 aluminum alloy, with a composition conforming to national standards. They are manufactured using hot forward extrusion. Figure 1 The photovoltaic frame shown is connected using corner bracket 100.

[0049] Key extrusion processes: Casting rod temperature 470-490℃; extrusion ratio > 40 when selecting an extrusion press; extrusion bar speed 4-7mm / s; exit temperature 520-535℃; and forced air cooling. The combined mold is not the focus of this invention and will not be described in detail.

[0050] After extrusion, it is cut into 6000 (0, +10) mm lengths and framed. It is then artificially aged at 165-170℃ for 8-10 hours. Afterward, it is cut into small parts of equal width, 16 (±0.05) mm. Interference points are pre-punched on the upper wall I 201 and upper wall II 301 at both ends of the processed long frame 200 and short frame 300.

[0051] Corner brackets 100 are inserted at the junctions of the long border 200 and the short border 300. In other words, they each have corresponding length specifications (e.g., Figure 2 As shown, the long frame 200 and the short frame 300 (the inner frame of the L-shape is shorter than the outer frame) surround the corresponding outer side of the corner piece 100 using the outer frame edge, and are embedded into the corresponding slot space using the inner frame edge. At this time, the base structure of the corner piece is embedded into the inner space of the long frame 200 and the short frame 300 respectively, namely cavity I 203 and cavity II 303, and so on.

[0052] Interference points I117 and II118 are made on interference surfaces I101 and III107, respectively. Furthermore, interference point III204 on upper wall I201 is staggered with interference point I117 on interference surface I101, further strengthening the connection strength. Similarly, interference point IV304 on upper wall II301 is staggered with interference point II118 on interference surface III107, further strengthening the connection strength.
