Description

Technical Field

[0001] The present application relates to the field of photovoltaic technology, and in particular to a component frame and a photovoltaic system. Background Art

[0002] With the increasing demands for solar panel power generation efficiency and the continued expansion of panel sizes, the demands for frame strength, torsion resistance, and extreme weather resistance are becoming increasingly stringent, along with increasingly stringent cost controls. The demand for new materials and structures is increasing, and the requirements are also becoming increasingly demanding. Existing photovoltaic system frames have low frame strength and cannot meet the load requirements of frames in specific environments. Furthermore, as demand for cell sizes increases, the load-bearing capacity of frames is increasingly demanded. Aluminum frames cannot meet the load requirements of general large-module applications. Sometimes, to increase quality or strength, the wall thickness is usually increased, which results in greater material loss and higher costs. Utility Model Content

[0043] This application provides a component border, such as Figures 1 to 6 As shown, the component frame includes a connected support unit 100 and a bending unit 200, a snap-in unit 300 and a first fixing member 400, the bending unit 200 is connected to one side of the support unit 100 along the second direction, the bending unit 200 includes a first bending panel 210 and a second bending panel 220 that are in contact with each other, the first bending panel 210 is bent at one end away from the support unit 100 to wrap the end of the second bending panel 220 away from the support unit 100; the snap-in unit 300 and the support unit 100 are arranged along the first direction and connected to the support unit 100, the snap-in unit 300 is a double-layer panel structure, the snap-in unit 300 includes an installation cavity 340 for installing a battery cell, and the second direction is perpendicular to the first direction; the first fixing member 400 is arranged on the cavity wall of the installation cavity 340 to connect the two panels of the snap-in unit 300.

[0044] The above-mentioned component frame includes a support unit 100, a bending unit 200 and a snap-in unit 300. The bending unit 200 is connected to the support unit 100, and the first bending panel 210 of the bending unit 200 is bent at one end away from the support unit 100, so that the first bending panel 210 wraps the end of the second bending panel 220 away from the support unit 100 to form a curling edge. The snap-in unit 300 is a double-layer panel structure. The first fixing member 400 is set on the cavity wall of the installation cavity 340 of the snap-in unit 300, thereby connecting and fixing the double-layer panel of the snap-in unit 300, enhancing the structural strength of the snap-in unit 300, and enhancing the installation stability of the component frame and the battery cell. The component frame of the present application is provided with a first fixing member 400 on the cavity wall of the installation cavity 340 of the connecting unit, thereby enhancing the structural strength of the component frame and improving the installation stability of the component frame and the battery cell.

[0045] Specifically, the component frame is made of steel. The present application uses steel to replace aluminum for the component frame, which can be manufactured through a high-precision cold bending forming process, and the forming, cutting, punching, end beveling, and corner code installation are all automated. The forming process no longer requires high-temperature boiler heating, and after forming and cooling, sandblasting and anodizing are not required, which reduces the generation of waste gas, dust, and waste liquid. Moreover, the raw material cost and processing cost of steel are low, which reduces the production cost. Compared with aluminum, steel has a large yield strength, which meets the load requirements of the component frame in specific environments and improves the bearing capacity of the component frame. The component frame of the present application,

[0046] More specifically, Figure 2 It is a cross-sectional view of the component frame. The component frame is manufactured through a high-precision cold-bending process, and the forming, cutting, punching, end beveling, and corner code installation are all automated. The component frame of this application uses high-strength structural steel, and the material yield strength reaches 350-550Mpa. For example, the material that can be used in this application is galvanized aluminum-magnesium material (that is, the surface of the structural steel is coated with a layer of zinc-aluminum-magnesium coating by the steel mill before leaving the factory). This material has very good anti-corrosion and anti-oxidation properties. At the same time, as needed, the component frame can be sprayed for corrosion protection for a second time to achieve a better anti-corrosion effect (that is, a layer of polyester coating is sprayed on the surface of the galvanized aluminum-magnesium material). In addition to achieving a better anti-corrosion effect, the color required for the operation can also be selected.

[0047] In some embodiments, as Figure 1 and Figure 2As shown, the snap-on unit 300 includes a first mounting portion 310, a second mounting portion 320, and a third mounting portion 330 that are sequentially connected to enclose a mounting cavity 340. The first mounting portion 310 is connected to the support unit 100. Adjacent two of the first mounting portion 310, the second mounting portion 320, and the third mounting portion 330 are arranged at an angle. A first fixing member 400 is disposed on the first mounting portion 310 to correspond to the two panel areas connected to the first mounting portion 310. The first mounting portion 310, the second mounting portion 320, and the third mounting portion 330 are sequentially connected and the first mounting portion 310 is connected to the support unit 100 to enclose the mounting cavity 340. The first fixing member 400 is disposed on the first mounting portion 310 to correspond to the two panel areas corresponding to the first mounting portion 310.

[0048] Specifically, if Figure 1 and Figure 2 As shown, the first fixing member 400 is a rivet point. Multiple first fixing members 400 are provided, spaced apart along the length of the module frame. The mounting cavity 340 has a double-layer structure at point Q. The fit of the two layers of material affects the product's load-bearing capacity. When the panel is loaded downward, there is a risk of detachment at this point. Therefore, a row of rivets is added at point Q to ensure a tighter fit and greater load-bearing capacity. More specifically, the first fixing member 400 is provided at point Q of the mounting cavity 340, which is the midpoint of the first mounting portion 310.

[0049] Specifically, if Figure 1 and Figure 2 As shown, the angle between the first mounting portion 310 and the second mounting portion 320 is 90°, and the first mounting portion 310 and the second mounting portion 320 are connected by a rounded corner, and the angle between the second mounting portion 320 and the third mounting portion 330 is an obtuse angle.

[0050] More specifically, if Figure 1 and Figure 2 As shown, side A of the module frame has a double-layer structure, initially straight, then sloping downward at a certain angle, with a transition arc added in the middle. When mounting the cell, a considerable amount of silicone needs to be injected into the mounting cavity 340. This silicone will overflow when the cell is inserted. Therefore, the third mounting portion 330 of the module frame is configured with a downward sloping structure, creating sufficient space within the mounting cavity 340 to hold the glue while preventing excess glue from overflowing. The addition of a transition arc between the second and third mounting cavities 340 reduces the overall rigidity of side A of the module frame, allowing for a certain degree of flexibility when subjected to reverse loads.

[0051] Preferably, if Figure 1 and Figure 2As shown, a drip-shaped transition circle is added to the end of the third mounting portion 330 facing away from the second mounting portion 320 to prevent cracking of the raw material, cracking of the coating, and thinning during a 180° bend, thereby preventing a reduction in corrosion resistance. More specifically, a drip-shaped transition circle is added at point U 350.

[0052] In some embodiments, as Figure 1 and Figure 2 As shown, the support unit 100 includes a first support plate 110, a second support plate 120, a third support plate 130, and a fourth support plate 140 connected end to end. The clamping unit 300 is connected to the connection between the first support plate 110 and the second support plate 120, and the bending unit 200 is connected to the connection between the third support plate 130 and the fourth support plate 140. The side surface of the third support plate 130 near the support unit 100 is provided with an inwardly concave recess 131. The first support plate 110, the second support plate 120, the third support plate 130, and the fourth support plate 140 are connected end to end to form the support unit 100. The first mounting portion 310 of the clamping unit 300 is connected to the connection between the first support plate 110 and the second support plate 120, and the bending unit 200 is connected to the connection between the third support plate 130 and the fourth support plate 140. An inwardly recessed portion 131 is provided on the side surface of the third support plate 130 close to the support unit 100 , so that the overall structure of the component frame has a stronger load-bearing capacity.

[0053] Specifically, the first support plate 110 , the second support plate 120 , the third support plate 130 and the fourth support plate 140 that are connected to each other at the end form a cavity 150 .

[0054] In some embodiments, the second support plate 120 is vertically disposed to the first support plate 110 .

[0055] In some embodiments, as Figure 1 and Figure 2 As shown, the angle between the second support plate 120 and the first support plate 110 is less than 90°. That is, the second support plate 120 is tilted downward. When installing the battery cell, it is required that there is a glue overflow effect at the bottom of the installation cavity 340, so that the glue can overflow a certain amount of silicone from the bottom of the installation cavity 340, that is, there must be glue overflow at the connection between the second support plate 120 and the third support plate 130. For this reason, the second support plate 120 of the present application is tilted downward to facilitate the smoothness of the silicone overflow. The angle between the second support plate 120 and the first support plate 110 is set to be less than 90°, so that the amount of glue between the battery cell and the installation cavity 340 of the component frame is greater. When the front is loaded, there is a larger buffer space, which is not easy to burst.

[0056] Specifically, if Figure 1 and Figure 2 As shown, the second support plate 120 and the third support plate 130 are connected by a chamfer 170, and the radius of the chamfer 170 ranges from R1.8 to R2.5. By limiting the connection between the second support plate and the third support plate 130 by the chamfer 170, not only is the safety of the component frame improved, but the chamfer 170 treatment can also remove sharp edges and burrs on the workpiece, preventing scratches on users or other objects. It also enhances product durability. The chamfer 170 treatment can disperse stress concentration and reduce the risk of parts breaking when subjected to stress, thereby improving product durability. In addition, by limiting the radius range of the chamfer 170, the chamfer 170 (R angle) is enlarged, facilitating the overflow of silicone from the installation cavity 340.

[0057] It should be noted that the unit of the fillet radius of the fillet 170 is mm, that is, the fillet radius of the fillet 170 is R1.8mm-R2.5mm.

[0058] Specifically, if Figure 1 and Figure 2 As shown, the fourth support plate 140 is provided with a reinforcing rib 160. The reinforcing rib 160 on the fourth support plate 140 strengthens the C-side of the module frame, thereby increasing the overall load-bearing capacity of the module frame. Furthermore, because the reinforcing rib 160 is provided on the side of the third support plate 130 facing away from the bending unit 200, the reinforcing rib 160 also acts as a torsion barrier, preventing the vertical side surface of the module frame from twisting.

[0059] More specifically, if Figure 1 and Figure 2 As shown, a plurality of reinforcing ribs 160 are provided, and the plurality of reinforcing ribs 160 are arranged at intervals along the length direction of the fourth support plate 140 .

[0060] In some embodiments, as Figure 1 and Figure 2 As shown, the component frame also includes a second fixing member 500, which is arranged on the side of the bending unit 200 close to the support unit 100 to connect the first bending panel 210 and the second bending panel 220. The bending unit 200 is a double-layer panel structure, and the bending unit 200 includes a first bending panel 210 and a second bending panel 220. The degree of fit between the first bending panel 210 and the second bending panel 220 affects the overall load resistance of the component frame. The second fixing member 500 is arranged on the side of the bending unit 200 close to the support unit 100 to ensure that the first bending panel 210 and the second bending panel 220 of the bending unit 200 are tightly fitted together.

[0061] Specifically, if Figure 1 and Figure 2As shown, the second fixing member 500 is a rivet point, and a plurality of second fixing members 500 are provided, and the plurality of second fixing members 500 are arranged at intervals along the length direction of the component frame. More specifically, the second fixing member 500 is provided at point D of the bending unit 200.

[0062] In some embodiments, as Figure 3 As shown, the first bending panel 210 is bent 180° at one end away from the support unit 100, so that the side of the bending unit 200 away from the support unit 100 forms a three-layer structure. After the first bending panel 210 is bent 180°, the end of the second bending panel 220 is wrapped to form a fastening and biting manner.

[0063] In some embodiments, as Figure 4 As shown, one end of the first bending panel 210 away from the support unit 100 and one end of the second bending panel 220 away from the support unit 100 are simultaneously bent 180°, so that the side of the bending unit 200 away from the support unit 100 forms a four-layer structure, the first bending panel 210 and the second bending panel 220 are bent 180° at the same time, and the first bending panel 210 wraps and presses the second bending panel 220 tightly.

[0064] The first bending panel 210 is bent 360° at one end away from the support unit 100, and the second bending panel 220 is bent 180° at one end away from the support unit 100, thereby forming a five-layer structure on the side of the bending unit 200 away from the support unit 100. After the first bending panel 210 is bent 360°, it wraps the second bending panel 220 bent 180° to form a mutually interlocking form.

[0065] Preferably, if Figure 1 and Figure 2 As shown, the component frame further includes a third fixing member 600 . The third fixing member 600 is disposed on a side of the bending unit 200 away from the supporting unit 100 to connect the bent first bending panel 210 and the second bending panel 220 .

[0066] Specifically, the third fixing member 600 is a rivet point, and a plurality of second fixing members 500 are provided, and the plurality of second fixing members 500 are arranged at intervals along the length direction of the component frame.

[0067] exist Figure 3 In the embodiment, after the first bending panel 210 is bent 180 degrees, a row of rivet points is added to engage the first bending panel 210 and the second bending panel 220 by riveting. Figure 4 In the embodiment, after the first bending panel 210 and the second bending panel 220 are synchronously bent 180 degrees, a row of rivet points is added to engage the first bending panel 210 and the second bending panel 220 by riveting. Figure 5 In the embodiment, when the first bending panel 210 is bent 360° and the second bending panel 220 is simultaneously bent 180°, a row of rivet points is added to engage the first bending panel 210 and the second bending panel 220 by riveting.

[0068] In some embodiments, the support unit 100 and the bending unit 200 are arranged along a second direction, wherein the second direction is perpendicular to the first direction.

[0069] In some embodiments, as Figure 2 As shown, the bottom edge of the support unit 100 forms an angle of 1° with the second direction, where the second direction is perpendicular to the first direction. With the connection between the bending unit 200 and the support unit 100 as the center, the 1° upward bend allows the first bending panel 210 and the second bending panel 220 of the bending unit 200 to fit more tightly, improving the overall load-bearing capacity.

[0070] In summary, the component frame of the present application has the following beneficial effects:

[0071] 1. The cold-bending forming process is adopted for manufacturing, and the overall dimensional tolerance is comparable to that of the aluminum alloy component frame. The energy consumption is only 1 / 3 of that of aluminum alloy forming. The surface coating of the raw materials has high corrosion resistance and no surface treatment is required. Therefore, no hazardous waste such as waste gas, waste liquid, and waste dust is generated, which is more in line with the trend of energy conservation, environmental protection and health.

[0072] 2. The strength of high-strength steel materials is more than twice that of aluminum materials, which can reduce wall thickness and greatly save material costs. In addition, the overall strength of the structure is greatly improved to meet the load requirements of special environments and large components.

[0073] 3. A new bite method is adopted at the material interface, which makes the bite tighter and the overall section stability better.

[0074] 4. By adding various reinforcing ribs 160 and riveting points (the first fixing member 400, the second fixing member 500 and the third fixing member 600), the structure can be made more stable and have better load-bearing and torsion resistance.

[0075] It should be noted that:

[0076] 1. High-strength steel materials generally use aluminum-magnesium-zinc-plated materials, and can also be replaced with Shagang's ultra-thin strip weathering steel. If there are higher anti-corrosion requirements, a layer of nano-anti-corrosion coating can be sprayed on the original surface of the material.

[0077] 2. The steel material can be S450GD, or higher grade materials can be used.

[0078] 3. The thickness of steel material can range from 0.5mm to 1.2mm.

[0079] 4. Cold roll forming: Cold roll forming (Cold Roll Forming) is a plastic deformation process that continuously bends metal sheets such as coils and strips horizontally through sequentially configured multi-pass forming rollers to form profiles with specific cross-sections.

[0080] The present application also provides a photovoltaic system including any of the above-mentioned module frames. The solar cells are mounted in the mounting cavity 340 of the module frame. Because the module frame is made of steel and a first fixing member 400 is provided on the wall of the mounting cavity 340 of the module frame, the structural strength of the module frame is further improved.

[0081] In some embodiments, the component frame includes a long component frame and a short component frame, and the long component frame and the short component frame are connected by a corner code 700. It should be noted that the long component frame and the short component frame have the same structure, but different lengths.

[0082] Specifically, the corner bracket 700 includes aluminum corner brackets and steel corner brackets. The pull-off force of the corner bracket 700 affects the bearing capacity of the entire component frame. In order to strengthen the pull-off force of the corner bracket 700, for the aluminum corner bracket solution, Figure 6 and Figure 7 As shown, this application uses six-point riveting on the component frame (such as Figure 6 As shown), and the riveting position is on the reinforcement rib of the corner code 700, and the riveting point 710 of the corner code 700 is as shown Figure 7 As shown, the serrations then clamp the rivet points, significantly increasing the pull-out force. For the steel angle bracket solution, two narrow waist holes are required near the ends of the component frame. After the steel angle bracket is inserted, the two elastic clamping points snap into the waist holes, and the pull-out force is over five times that of a normal aluminum angle bracket.

[0083] It should be noted that aluminum alloy angle brackets are generally used for connecting angle brackets, but steel angle brackets can also be used, and the fastening methods are slightly different.

[0084] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned 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.
