Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaics, and in particular to an aluminum photovoltaic frame and a photovoltaic component. Background Art

[0002] The installation of photovoltaic panels is relatively unified in the industry. Usually, the required aluminum photovoltaic frame is extruded, cut into 2 long and 2 short pieces, and the assembled photovoltaic panels are inserted into the notches of the aluminum photovoltaic frame. The notches are regulated by sealant, and the four corners of the photovoltaic module are combined by corner code clearance matching and interference point fixing. Of course, the shortcomings of the aluminum photovoltaic frame are also obvious. Since the notch is in a cantilever state, the complex overflow glue groove is difficult to form on the cantilever structure, and the overflow glue groove is easily scraped into a tumor, resulting in assembly explosion. The subsequent sandblasting or shot blasting process can only reduce the width of the receiving groove. If the width of the receiving groove is qualified during the extrusion process, the subsequent sandblasting or shot blasting may also reduce the width of the receiving groove, and there is also the risk of assembly explosion.

[0029] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific embodiments of the utility model are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0030] Embodiment 1:

[0031] Figure 1 A schematic cross-sectional view of an aluminum photovoltaic frame provided in Embodiment 1 of the present utility model; Figure 2 A schematic cross-sectional view of a frame body in an aluminum photovoltaic frame provided in Embodiment 1 of the present utility model; Figure 1-Figure 2 As shown, the aluminum photovoltaic frame provided in the first embodiment of the utility model includes a frame body 100 and a groove forming member 200, the frame body 100 has a first plug-in portion 110, the groove forming member 200 has a first bent plate portion 210 and a second plug-in portion 220 integrally formed and connected, the first bent plate portion 210 and the first outer side 140 of the frame body 100 form a receiving groove 300 for accommodating a photovoltaic panel 400; the first plug-in portion 110 and the second plug-in portion 220 are fixedly plugged.

[0032] Figure 1In the figure, the left side of the frame body 100 is the first outer side 140 of the frame body 100. The first plug-in portion 110 is also located at the left half of the frame body 100, and the receiving groove 300 formed by the first curved plate portion 210 of the groove forming member 200 and the left side of the frame body 100 is on the left side of the frame body 100.

[0033] The aluminum photovoltaic frame is separated into a frame body 100 and a groove forming member 200, so that the groove forming member 200 is formed separately, and then the first plug-in portion 110 and the second plug-in portion 220 are plugged together to form the frame body 100 and the groove forming member 200, and a receiving groove 300 is formed between the groove forming member 200 and the first outer side 140 of the frame body 100 to accommodate the photovoltaic panel 400. Thus, the semi-open receiving groove 300 is eliminated on the frame body 100, and the difficulty of molding is reduced.

[0034] like Figure 2 As shown, preferably, the first plug-in portion 110 includes a second bent plate portion 111 , and the second bent plate portion 111 and the second outer side 150 of the frame body 100 form a first plug-in slot 120 , and the second plug-in portion 220 is plugged into the first plug-in slot 120 and matches the first plug-in slot 120 .

[0035] In this embodiment, the second outer side 150 of the frame body 100 is the lower side of the frame body 100 as shown in the figure. The first plugging slot 120 formed by the first plugging portion 110 and the second outer side 150 of the frame body 100 is located at the lower side of the frame body 100 as shown in the figure.

[0036] The second plug-in portion 220 is plugged into the first plug-in slot 120 and matches the first plug-in slot 120, which means that the cross-sectional size and shape of the second plug-in portion 220 are consistent with the corresponding size and shape of the first plug-in slot 120. When the second plug-in portion 220 is inserted into the first plug-in slot 120, the second plug-in portion 220 will not shake in the first plug-in slot 120.

[0037] The second plug-in portion 220 is plugged into the first plug-in slot 120 to facilitate the connection between the slot forming component 200 and the frame body 100. After the two are formed separately, the slot forming component 200 and the frame body 100 can be connected by simply inserting the second plug-in portion 220 along the length direction of the first plug-in slot 120, thereby improving the assembly efficiency.

[0038] like Figure 1 and Figure 2 As shown, preferably, the opening direction of the first plugging slot 120 is away from the first bent plate portion 210 .

[0039] That is, Figure 1The opening direction of the first plugging slot 120 may be toward the right side in the figure. The first bent plate portion 210 is located on the left side of the first plugging slot 120 in the figure.

[0040] The opening direction of the first plug-in slot 120 is set to the above direction, and the other part of the slot forming member 200 is located on the back side of the slot bottom of the first plug-in slot 120. When the second plug-in portion 220 tends to detach from the first plug-in slot 120, the other part of the slot forming member 200, such as the first bent plate portion 210, is used to abut against the back side of the slot bottom of the first plug-in slot 120 for limiting, thereby realizing the first plug-in slot 120 limiting the slot forming member 200 in two directions.

[0041] In another implementation, if the opening direction of the first plug slot 120 is toward the first bent plate portion 210, when the slot opening width of the first plug slot 120 described later is smaller than the slot bottom width, the slot forming member 200 can also be limited in two opposite directions.

[0042] like Figure 1 As shown, preferably, the slot width of the first inserting slot 120 is smaller than the slot bottom width.

[0043] That is, the cross section of the first plug slot 120 is a trapezoid, which can be an isosceles trapezoid in this embodiment, with the top of the trapezoid being the notch and the bottom of the trapezoid being the bottom of the groove. Correspondingly, the cross section of the first plug portion 110 is also a trapezoid. Furthermore, it can be an isosceles trapezoid, with the width of the free end of the cross section of the first plug portion 110 being greater than the width of the root of the cross section of the first plug portion 110.

[0044] By setting the shape of the first plug-in slot 120 to the above shape, a shape with a small slot opening and a large slot bottom can be formed. After the second plug-in portion 220 is inserted into the first plug-in slot 120, the first plug-in slot 120 of this shape can limit the second plug-in portion 220 from escaping along the opening direction of the first plug-in slot 120. Only by the cooperation between the first plug-in slot 120 and the second plug-in portion 220, the slot forming member 200 can be limited in two opposite directions.

[0045] Figure 3 A schematic cross-sectional view of a groove-forming member in an aluminum photovoltaic frame provided in Embodiment 1 of the present utility model; Figure 3 As shown, preferably, the slot forming member 200 includes a third bent plate portion 230 and a fourth bent plate portion 240 , the third bent plate portion 230 connects the fourth bent plate portion 240 and the first bent plate portion 210 , and the second plug-in portion 220 is located at an end of the fourth bent plate portion 240 away from the third bent plate portion 230 .

[0046] Specifically, in this embodiment, the third curved plate portion 230 and the fourth curved plate portion 240 are both L-shaped, and the third curved plate portion 230 and the fourth curved plate portion 240 form an approximately closed structure. Figure 1 In the embodiment, an opening is formed in the upper left region of the third bent plate portion 230 and the fourth bent plate portion 240 to accommodate the bottom of the first insertion slot 120 .

[0047] By setting the third bent plate portion 230 and the fourth bent plate portion 240, and using a part of the fourth bent plate portion 240 as the second plug-in portion 220 to be inserted into the first plug-in slot 120, a part of the third bent plate portion 230 can be used to press against the back side of the bottom of the first plug-in slot 120, thereby preventing the slot forming member 200 from moving toward the direction close to the frame body 100.

[0048] like Figure 1-Figure 3 As shown, preferably, the third bent plate portion 230 and the fourth bent plate portion 240 form a second plugging slot 250 , and a portion of the second bent plate portion 111 is inserted into the second plugging slot 250 and matches with the second plugging slot 250 .

[0049] Specifically, an L-shaped edge of the third bent plate portion 230 that is not connected to the first bent plate portion 210 and the fourth bent plate portion 240 form a second plug-in slot 250, and the second plug-in slot 250 accommodates a portion of the second bent plate portion 111, that is, the side wall of the non-second outer edge 150 that forms the first plug-in slot 120 is inserted into the second plug-in slot 250.

[0050] By partially inserting the second bent plate portion 111 into the second plug-in groove 250, two plug-in structures can be formed between the frame body 100 and the groove forming component 200, that is, the second plug-in portion 220 is inserted into the first plug-in groove 120, and the second bent plate portion 111 is partially inserted into the second plug-in groove 250, thereby improving the connection firmness between the frame body 100 and the groove forming component 200.

[0051] like Figure 3 As shown, preferably, the slot width of the second inserting slot 250 is smaller than the slot bottom width.

[0052] Since the slot width of the first insertion slot 120 is smaller than the slot bottom width, a side wall of the first insertion slot 120, i.e., the second bent plate portion 111, is Figure 1 The lower portion shown in the figure is in a state where the free end width is large and the root width is small, and the second curved plate portion 111 is Figure 1 The lower portion shown is the portion inserted into the second insertion slot 250. Therefore, the slot width of the second insertion slot 250 is smaller than the slot bottom width. That is, the cross-sectional shape of the second insertion slot 250 is roughly a right-angled trapezoid, the top of the right-angled trapezoid is located at the slot, and the bottom of the right-angled trapezoid is the slot bottom.

[0053] When the slot width of the second plug-in slot 250 is smaller than the slot bottom width, the second bent plate portion 111 is not easy to be directly pulled out from the second plug-in slot 250 along the direction in which the slot forming member 200 is separated from the frame body 100. Therefore, through the cooperation between the first plug-in slot 120 and the second plug-in portion 220, and the cooperation between the second plug-in slot 250 and the second bent plate portion 111, the frame body 100 and the slot forming member 200 can be positioned in two opposite directions in both plug-in structures, thereby significantly increasing the degree of connection firmness between the frame body 100 and the slot forming member 200.

[0054] like Figure 3 As shown, preferably, a glue overflow groove 260 is provided on the side wall of the first bent plate portion 210 facing the first outer side edge 140 , and the glue overflow groove 260 is located at a part of the side wall away from the second plug-in portion 220 .

[0055] When the receiving groove 300 receives the photovoltaic panel 400, the receiving groove 300 is filled with the sealant 500. By providing the overflowing glue groove 260 on the side wall of the first curved plate portion 210 facing the first outer side edge 140, after the photovoltaic panel 400 is placed in the receiving groove 300, the overflowing glue generated by the placement of the photovoltaic panel 400 can be stored, so as to prevent the sealant 500 from excessively flowing onto the surface of the photovoltaic panel 400 and interfering with the operation of the photovoltaic panel 400.

[0056] like Figure 2 As shown, preferably, the frame body 100 has a closed cavity structure, and the inner side surface of the closed cavity structure is provided with a positioning ridge 130.

[0057] The positioning ridge 130 is arranged on the back side of the first outer side 140 and the opposite side of the side. The closed cavity structure means that in the cross section, the inner side of the frame body 100 has a closed edge formed by a closed pattern, and the space in the non-closed cavity is completely isolated from the outside.

[0058] By providing the positioning ridges 130 on the inner side surface of the closed cavity structure of the frame body 100 , it is possible to facilitate positioning of the frame body 100 and adjacent components, thereby improving the installation accuracy of the frame body 100 .

[0059] Embodiment 2:

[0060] Figure 4 A schematic cross-sectional view of a photovoltaic assembly provided by an aluminum photovoltaic frame provided in Embodiment 2 of the present utility model; Figure 4 As shown, the second embodiment further provides a photovoltaic assembly, including a photovoltaic panel 400 and the above-mentioned aluminum photovoltaic frame, and the edge of the photovoltaic panel 400 is accommodated in the accommodation groove 300.

[0061] The containing groove 300 is provided with a sealant 500. After the sealant 500 dries, it can fix the photovoltaic panel 400 and the aluminum photovoltaic frame on one hand, and fill the space between the two on the other hand.

[0062] By arranging the above-mentioned aluminum photovoltaic frame in the photovoltaic module, the photovoltaic module accordingly has all the advantages of the above-mentioned aluminum photovoltaic frame, which will not be described one by one here.

[0063] In order to produce the above-mentioned aluminum photovoltaic frame, the aluminum alloy can be hot extruded to produce the frame body and the groove forming parts. The specific mold form for producing the two is not limited, it is not the focus of this application, and will not be repeated. After the two are extruded separately, they can be cut according to the size of 6050mm, where the upper deviation of the size is 20mm and the lower deviation is 0mm. Then ageing is carried out. The process parameters for aging are as follows: the aging temperature is 185℃~195℃, and the aging time is 3h~4h. Then sandblasting or shot blasting process is carried out. If the sandblasting process is adopted, the particle size of the glass sand used is 40 mesh~80 mesh, and the sandblasting speed is selected from 25Hz~35Hz. Then conventional anodizing is carried out. Anodizing belongs to the conventional technology in this field, and the specific process will not be repeated.

[0064] Then, further processing is carried out, and the frame body and the groove forming parts are cut according to the dimensions of 1000mm for the short dimension and 2000mm for the long dimension respectively. The lower deviation of the above two dimensions is 0mm, and the upper deviation is 0.5mm. The frame body and the groove forming parts with a short dimension of 1000mm are used to fix the short side of the photovoltaic panel, while the long dimension is used to fix the long side of the photovoltaic panel. After cutting into the above dimensions, the groove forming parts are inserted into the frame body to form an aluminum photovoltaic frame, and the long and short aluminum photovoltaic frames are cut at a 45° angle, wherein the side where the groove forming parts are located is smaller in size. The photovoltaic panel is inserted into the receiving groove, and sealant is applied. The two long and two short aluminum photovoltaic frames are combined to form a rectangle, and fixed with corner codes at the four corners. Among them, the corner code is a conventional technology in this industry and will not be described in detail.
