Detailed implementation manners

[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0038] Please refer to Figure 2 , Figure 2 which is a schematic structural diagram of a photovoltaic module frame provided by an embodiment of the present utility model. The photovoltaic module frame 4 may include: a bearing assembly 9 and a limiting assembly 5; one end of the limiting assembly 5 is connected to the bearing assembly 9, and the other end extends in a direction away from the bearing assembly 9; the bearing surface of the bearing assembly 9 is used for adhesively connecting to the backlight surface of the module laminate 3; the limiting assembly 5 is used for adhesively connecting to the side surface of the module laminate 3;

[0039] The surface of the limiting assembly 5 facing away from the bearing assembly 9 does not exceed the light-facing surface of the module laminate 3; a first arc-shaped glue storage groove 6 is formed on the side of the limiting assembly 5 facing the module laminate 3;

[0040] The bearing assembly 9 includes a cavity 91 and a support arm 92 that extends obliquely away from the limiting assembly 5 from the cavity 91, and a V-shaped glue storage groove 8 is formed between the cavity 91 and the support arm 92.

[0041] It should be noted that in the photovoltaic module frame 4 provided in this embodiment, the light-facing surface of the limiting assembly 5 and the light-facing surface of the module laminate 3 do not exceed the light-facing surface of the module laminate 3. As Figure 3 shown, it will not block the dust 1 on the light-facing surface of the module laminate 3, enabling the dust 1 to naturally fall off along the light-facing surface of the module laminate 3, thus solving the problem of module dust accumulation. Moreover, the entire side surface of the limiting assembly 5 from the light-facing surface to the bearing surface of the bearing assembly 9 is designed as an arc-shaped groove as the glue storage groove, increasing the glue storage space and preventing the silicone 2 from overflowing to the light-facing surface of the module laminate 3, thereby avoiding the problem of poor silicone 2 overflow.

[0042] This embodiment does not limit the specific type of the limiting assembly 5. For example, the limiting assembly 5 may be an alloy assembly or a composite material assembly; the alloy assembly may include an aluminum alloy assembly or a steel material assembly. It should be noted that the alloy assembly is made of a material formed by melting and mixing two or more metals or other elements, and the composite material assembly is usually made of a combination of multiple materials. The materials of these two assemblies are existing.

[0043] This embodiment does not limit the specific width of the surface of the limiting component 5 facing away from the bearing component 9. For example, the width of the surface of the limiting component 5 facing away from the bearing component 9 can be 0-5 mm, including the value at the right end. This embodiment does not limit the specific size of the first arc-shaped glue storage groove 6, which can be defined according to the specific structure of the limiting component 5.

[0044] It should be noted that in this embodiment, the bearing component 9 includes a cavity 91 and a support arm 92 that extends obliquely away from the limiting component 5. The support arm 92 further extends the bearing surface of the bearing component 9 to the outside. A V-shaped glue storage groove is formed between the cavity 91 and the support arm 92, and the overall forms a Y-shaped structure. By designing the bearing component 9 into a Y-shaped structure, on the one hand, it increases the contact area between the bearing surface and the component laminate 3, enhancing the support of the bearing surface for the component laminate 3; on the other hand, the V-shaped glue storage groove 8 at the connection can increase the adhesion between the component laminate 3 and the bearing component 9, and can also store the silicone glue 2 that overflows during the advancement of the component laminate 3 in the installation process, preventing it from overflowing outside the frame and causing poor glue overflow.

[0045] This embodiment does not limit the specific structure of the cavity 91, which can include but is not limited to a bearing plate 911, a first support plate 912, a bottom plate 913, and a second support plate 914 that are connected in sequence to enclose the cavity 91; at the position where the bearing plate 911 and the first support plate 912 are connected, one end of the limiting component 5 is connected to the bearing plate 911.

[0046] This embodiment does not limit the specific type of the support arm 92. For example, the support arm 92 can be an alloy component or a composite material component; the alloy component can include an aluminum alloy component or a steel component. This embodiment does not limit the specific type of the bearing plate 911. For example, the bearing plate 911 can be an alloy component or a composite material component; the alloy component can include an aluminum alloy component or a steel component. This embodiment does not limit the specific type of the first support plate 912. For example, the first support plate 912 can be an alloy component or a composite material component; the alloy component can include an aluminum alloy component or a steel component. This embodiment does not limit the specific type of the bottom plate 913. For example, the bottom plate 913 can be an alloy component or a composite material component; the alloy component can include an aluminum alloy component or a steel component. This embodiment does not limit the specific type of the second support plate 914. For example, the second support plate 914 can be an alloy component or a composite material component; the alloy component can include an aluminum alloy component or a steel component.

[0047] This embodiment does not limit the specific length of the entire bearing surface. For example, the length of the entire bearing surface can be greater than the length of the component laminate 3, that is, the end of the support arm 92 away from the cavity 91 can extend beyond the central position in the extending direction of the component laminate 3.

[0048] This embodiment does not limit the specific lengths of the bearing surfaces of the cavity 91 and the support arm 92. For example, the length of the bearing surface of the cavity 91 can be greater than the length of the bearing surface of the support arm 92; it can also be equal to or less than the length of the bearing surface of the support arm 92. It should be noted that one end of the component laminate 3 is adhesively connected to the limiting component 5, and the backlight surface of the component laminate 3 is adhesively connected to the bearing surface of the bearing component 9. When the length of the bearing surface of the cavity 91 is greater than the length of the bearing surface of the support arm 92, the position of the V-shaped glue storage groove 8 on the bearing surface of the bearing component 9 is closer to the end of the component laminate 3 that is not adhesively connected to the limiting component 5, which can further enhance the adhesive force between the end of the component laminate 3 that is not adhesively connected to the limiting component 5, the silica gel 2, and the bearing surface, so that the component laminate 3 can be more firmly adhesively connected to the surface of the bearing component 9.

[0049] Furthermore, in this embodiment, a plurality of bottom glue storage grooves 7 can be uniformly arranged on the bearing surface of the cavity 91. It should be noted that in this embodiment, by adding a plurality of bottom glue storage grooves 7 to the bearing surface of the cavity 91, on the one hand, the glue storage effect of the silica gel 2 on the backlight surface of the component laminate 3 can be further enhanced, and on the other hand, the adhesive force between the component laminate 3, the silica gel 2, and the bearing surface can also be further enhanced. This embodiment does not limit the specific dimensions of the bottom glue storage grooves 7, which can be defined according to the specific structure of the bearing component 9. For example, the width of the notch of the bottom glue storage groove 7 can be 0.1 mm - 5 mm, including both ends; the depth of the bottom glue storage groove 7 can be 0.1 mm - 5 mm, including both ends.

[0050] Furthermore, in this embodiment, the depth of the V-shaped glue storage groove 8 can be greater than the depth of the bottom glue storage groove 7. It should be noted that in this embodiment, by deepening the design of the V-shaped glue storage groove 8, the adhesive force between the component laminate 3 and the bearing component 9 can be further increased, as well as the glue storage capacity for preventing the silica gel 2 from overflowing during the advancement of the component laminate 3.

[0051] This embodiment does not limit the specific dimensions of the V-shaped glue storage groove 8, which can be defined according to the specific structure of the bearing component 9. For example, the width of the notch of the V-shaped glue storage groove 8 can be 1 mm - 5 mm, including both ends; the depth of the V-shaped glue storage groove 8 can be 0.5 mm - 5 mm, including both ends.

[0052] Furthermore, in this embodiment, a protruding structure 921 is formed on one side of the support arm 92 facing the V-shaped glue storage tank 8; a table 81 is formed on one side of the V-shaped glue storage tank 8 facing the support arm 92; a second arc-shaped glue storage tank 82 is formed between the table 81 and the protruding structure 921; and the V-shaped glue storage tank 8 includes a first glue storage area below the table 81 and a second glue storage area above the table 81. It should be noted that in this embodiment, the V-shaped glue storage tank 8 is divided into a first glue storage area below the table 81 and a second glue storage area above the table 81, and an arc-shaped glue storage tank is formed in the second glue storage area, which is concave toward the support arm 92, so as to prevent the silica gel from overflowing in the process of advancing from the bearing surface of the support arm 92 to the bearing surface of the cavity 91.

[0053] The photovoltaic module frame provided by the embodiment of the utility model can make dust fall naturally along the module laminate to the light surface, thereby solving the problem of dust accumulation on the module; it can enhance the support of the bearing surface to the module laminate; it can prevent silicone from overflowing to the outside of the module laminate, thereby avoiding the problem of silicone overflow.
