Detailed Description

The application provides a dual glass assembly of high two-sided rate specifically sees the embodiment.

The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Before describing the specific embodiments, the structure of the conventional dual glass assembly of the related art will be briefly described. Referring to fig. 1 to 3, the structure shown in fig. 1 is a structural diagram and a partial enlarged view of a conventional dual glass assembly, wherein 1 is an aluminum frame, 2 is a laminate, and 3 is a packaging adhesive; referring to fig. 2, fig. 2 is a cross-sectional view of an aluminum frame 1, wherein a side a faces upward, a side B faces an upright surface and faces the outside of the dual glass assembly, and a side C is a fixing and mounting surface of the bottom, and it can be seen from the cross-sectional view of the frame shown in fig. 2 that the side C of the frame shields the battery on the back of the assembly to a certain extent, which may affect the power generation efficiency on the back of the assembly. The C side of the frame is mainly used for mounting the components. The installation of the components in the power station mainly adopts two modes of bolt installation and pressing block installation, when the bolt installation is selected, the installation is mainly carried out by using the installation hole on the edge C, and the installation schematic diagram is shown in figure 3.

In order to reduce the shielding of the battery piece on the back of the assembly by the C edge of the frame on the premise of ensuring that the installation is not influenced, the frame structure is redesigned, the C edge of the installation is designed below the cavity, and the size is ensured to accommodate the bolt and the gasket, specifically see the following two embodiments.

The first embodiment is as follows:

as shown in fig. 4 to 7, a dual glass assembly with high double-sided rate according to an embodiment of the present invention includes an aluminum frame 1 and a laminated member 2 whose edges are encapsulated in the aluminum frame 1, and during encapsulation, the two glass assemblies are connected and sealed by an encapsulation adhesive 3; the aluminum frame 1 comprises a packaging groove 11, a supporting cavity part 12 and a fixed mounting part 13; the laminated part 2 comprises glass 201, a laminated adhesive film 202, a photovoltaic cell 203, a laminated adhesive film 202 and the glass 201 from top to bottom in sequence; coating the packaging glue 3 in the packaging groove 11 of the aluminum frame 1, and then buckling the packaging groove 11 coated with the packaging glue 3 into the edge of the laminating part 2 to finish the packaging of the laminating part 2; after packaging, the aluminum frame 1 seals and packages the laminated part 2 at the middle position from the periphery;

specifically, the aluminum frame 1 includes a packaging groove 11, a supporting cavity portion 12 and a fixing mounting portion 13, as shown in fig. 1 and fig. 2, the packaging groove 11 and the fixing mounting portion 13 are both groove-shaped structures which are open towards the inner side (the middle position where the laminating member 2 is located is the inner side), the cross section of each groove is in a half-square structure, the supporting cavity portion 12 connects and supports the packaging groove 11 and the fixing mounting portion 13 to form a square-tube-shaped cavity structure, and the cross section of each cavity structure is in a square shape;

in order to reduce the shielding of the C edge of the aluminum frame on the back surface of the laminated piece 2, the C edge for installing the bolt 4 in the prior art is shortened, the position is changed, the original cavity extends inwards and is changed into a position designed below the cavity, and a fixed installation part 13 with a half-square cross section is formed and is used for accommodating the bolt 4 and the gasket 8; after the C edge is shortened, the whole width of the frame is 17-30 mm, and the aluminum frame of the embodiment is 18mm.

Because the height of the fixed mounting part 13 is limited, namely the height of the mounting space of the bolt 4 is limited, in order to ensure that the bolt 4 can be smoothly placed into the fixed mounting part 13 when the assembly is mounted, the bottom surface of the fixed mounting part 13 is provided with the open mounting hole 14, compared with the closed mounting hole in the prior art, the effect of convenient assembly is realized; referring to fig. 7, in fig. 7, 6 is a supporting surface for assembly, in an actual application scene, generally a supporting beam of a photovoltaic support, and 7 is a spring washer, which plays a role in increasing friction force between the nut 5 and the bolt 4, and plays a better role in shock resistance and fastening; as can be seen from comparison between fig. 7 and fig. 3, the shielding of the side C of the aluminum frame in the embodiment to the back of the laminated member 2 is significantly smaller than that in the prior art, and the design purpose can be achieved.

The second embodiment:

as shown in fig. 8 to 11, a second embodiment of the present invention provides another dual-glass assembly with high double-sided rate, which is similar to the first embodiment, and only the opening direction of the fixing mounting portion 13 of the aluminum frame 1 is different, in this embodiment, the opening directions of the sealing groove 11 and the fixing mounting portion 13 are opposite, the sealing groove 11 is open towards the inside, and the fixing mounting portion 13 is open towards the outside, specifically refer to fig. 8, 9 and 10;

the advantage of the outward opening of the fixing and mounting portion 13 is that the assembly is more convenient, and in the first embodiment, because the opening of the fixing and mounting portion 13 faces inward, when assembling, an operator needs to perform fastening operation under the assembly, which is inconvenient for observation and effort; in the structure of the second embodiment, when assembling, an operator can fasten the component, so that the fastening operation is intuitive and convenient, and the assembling effect is as shown in fig. 11.

The above examples were tested to obtain the following test data:

as shown in FIG. 2, frame C limit size is 30mm minimum among the prior art, the utility model discloses the shown frame C limit size of embodiment can reduce to 18mm, and the frame reduces 20% -40% to the area that shelters from of subassembly, and subassembly back efficiency promotes and can reach 3% the most, and the two-sided rate of corresponding subassembly promotes and can reach 3% the most.
