Description

Technical Field

[0002] The frame of a photovoltaic module is an important part of a photovoltaic module. It is generally wrapped around the photovoltaic laminate to form a photovoltaic module with basic strength protection. The frame of a photovoltaic module can improve the mechanical strength of the module and can be fixed to the outside through the frame. In the structure of a traditional photovoltaic module, the frame is wrapped around the top surface (light-receiving surface), side surface and bottom surface (backlight surface) of the edge of the laminate. However, in this wrapping method, the frame is higher than the surface of the laminate on the top and bottom surfaces of the laminate. The height difference structure formed is easy to accumulate dust during use, which reduces the power generation efficiency of the photovoltaic module on the one hand, and causes hot spots on the laminate in the dust-blocked area on the other hand, causing damage to the photovoltaic module. Removing the structure where the frame is higher than the surface of the laminate will result in an unstable connection between the frame and the laminate.

[0036] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] The photovoltaic module frame is an important part of the photovoltaic module. It is generally wrapped around the photovoltaic laminate to form a photovoltaic module with basic strength protection. The photovoltaic module frame can improve the mechanical strength of the module and can be fixed to the outside through the frame. In the traditional photovoltaic module structure, the frame is wrapped on the top surface (light-receiving surface), side surface and bottom surface (backlight surface) of the edge of the laminate. However, in this wrapping method, the frame is higher than the surface of the laminate on the top and bottom surfaces of the laminate, which has the following problems:

[0038] (1) The height difference structure formed is easy to form dust accumulation on the surface of the laminate during use, which not only reduces the power generation efficiency of the photovoltaic module, but also causes hot spots on the laminate in the dust-blocked area, causing damage to the photovoltaic module;

[0039] (2) Simply removing the portion of the frame that protrudes above the top surface of the laminate may easily cause the laminate to detach from the frame in harsh environments such as strong winds, reducing the stability of the connection between the frame and the laminate and causing the overall stability of the assembly to decrease.

[0040] Therefore, how to provide a photovoltaic module frame to avoid dust accumulation on the surface of the laminate in the photovoltaic module, which in turn leads to a decrease in the power generation efficiency and service life of the photovoltaic module, while ensuring the stability of the connection between the frame and the laminate, is a technical problem that technical personnel in this field urgently need to solve.

[0041] The utility model sets the edge contour of the inner frame and the edge contour of the outer frame so that they do not exceed the light-receiving surface of the laminate during installation, thereby avoiding the formation of a structure that has a height difference with the light-receiving surface on the light-receiving surface of the laminate, forming a dust-blocking structure, and improving the power generation efficiency and service life of the photovoltaic module. At the same time, the photovoltaic module frame is set to be composed of an inner frame and an outer frame, and the inner and outer frames are connected by a concave-convex combination through a surface convex or concave structure, forming a package on the side and backlight surface of the laminate, and the inner frame is connected to the laminate through a lamination process, thereby avoiding the problem of unstable connection of the photovoltaic module frame due to reducing the frame of the light-receiving surface of the laminate. The following embodiments can be referred to:

[0042] Embodiment 1:

[0043] Please refer to Figure 1 , Figure 1A schematic diagram of the structure of a photovoltaic module frame connected to a laminate provided in an embodiment of the utility model. The photovoltaic module frame may include:

[0044] An inner frame 10 and an outer frame 20;

[0045] The inner frame 10 is fixedly connected to the side of the laminate 1 by lamination, and the inner frame 10 has a first surface structure connected to the outer frame 20;

[0046] The outer frame 20 is used to carry the laminate 1 and the inner frame 10, and the outer frame 20 is provided with a second surface structure that is installed in cooperation with the first surface structure;

[0047] After installation, the inner frame 10 and the outer frame 20 do not extend beyond the light-receiving surface of the laminate 1 .

[0048] It should be noted that, in the present embodiment, the frame of the photovoltaic module is composed of an inner frame 10 and an outer frame 20, and the inner frame 10 is installed in coordination with the outer frame 20, and at the same time, the inner frame 10 is fixedly connected to the side of the laminate 1 by lamination, and the inner frame 10 and the side of the laminate 1 are connected by lamination heating to ensure the stability of the connection between the inner frame 10 and the side of the laminate 1, and the inner frame 10 is installed in coordination with the outer frame 20 to achieve the connection between the inner frame 10 and the outer frame 20, and at the same time, the inner frame 10 and the outer frame 20 are arranged not to exceed the light-receiving surface of the laminate 1 after installation, and under the premise that there is no height difference between the frame of the photovoltaic module and the top surface of the laminate 1, the stability of the connection between the frame of the photovoltaic module and the laminate 1 can be ensured through the above connection. It should be further explained that, in this embodiment, the inner frame 10 can be set to be slightly larger than the side of the laminate 1, or the inner frame 10 can be set to be slightly smaller than the side of the laminate 1. At this time, the volume of the inner frame 10 does not affect the lamination heating treatment with the laminate 1, and the volume of the outer frame 20 is larger than that of the inner frame 10, and is used to support the laminate 1. During installation, the inner frame 10 and the laminate 1 are first connected by lamination heating, and adhesive can be set in the area where the inner frame 10 and the laminate 1 are connected, so that the inner frame 10 and the laminate 1 are connected by lamination heating using adhesive, and then the inner frame 10 connected to the laminate 1 is set to be connected to the outer frame 20, forming a structure in which there is no height difference between the frame of the photovoltaic module and the top surface of the laminate 1, while ensuring the stability of the connection between the frame of the photovoltaic module and the laminate 1, and through the step-by-step connection method, it is also ensured that the connection process of the frame of the photovoltaic module and the laminate 1 is completed efficiently.

[0049] The side of the laminate 1 in this embodiment is the side of the laminate 1 in the conventional sense. The laminate 1 is formed by stacking multiple layers, and the side surface formed along the stacking direction at a certain height is the side of the laminate 1. After the inner frame 10 and the laminate 1 enter the laminator, the laminate 1 is heated and the glue overflows and adheres to the inner frame 10. In this embodiment, four inner frames 10 can be set corresponding to one laminate 1, and the four inner frames 10 are connected to the four side surfaces of the laminate 1, forming protection around the side of the laminate 1.

[0050] In addition, in this embodiment, the outer frame 20 includes a surface connected to the backlight surface of the laminate 1, so as to support the laminate 1 on the bottom side of the laminate 1. In this embodiment, the specific method of the outer frame 20 and the inner frame 10 for installation is not limited, as long as the outer frame 20 and the inner frame 10 can be firmly connected. For example, a convex structure can be set in the area connected to the inner frame 10 in the outer frame 20, and a concave structure matching the convex structure can be set in the inner frame 10 to achieve the connection between the inner and outer frames; or a concave structure can be set in the outer frame 20, and a convex structure can be set in the inner frame 10; or a concave structure and a convex structure can be set in the outer frame 20 at the same time, and a convex structure and a concave structure matching therewith can be set in the inner frame 10. It should be further explained that in this embodiment, the convex structure and the concave structure can be alternately and continuously set, that is, set as a wavy surface structure to ensure the preparation density and improve the stability of the connection. The convex structure and the concave structure set in this embodiment can also be set in a variety of shapes. Accordingly, in this embodiment, the outer frame 20 can be connected to the side surface of the inner frame 10 facing away from the side of the laminate 1, or can also be connected to the side surface of the inner frame 10 facing the side of the laminate 1, and this embodiment is not limited to this. This embodiment does not limit the specific shape of the inner frame 10. For example, the inner frame 10 can be set to a rectangular inner frame 10 corresponding to the side of the laminate 1, or the inner frame 10 can also be set to other shapes.

[0051] Further, please refer to Figure 2 , Figure 2 Another schematic diagram of the structure of a photovoltaic module frame connected to a laminate provided by an embodiment of the utility model. In order to further ensure the stability of the connection between the inner frame 10 and the side of the laminate 1, the inner frame 10 may be bent to form a limiting structure 11 that abuts against the backlight surface of the laminate 1.

[0052] It should be noted that, in this embodiment, the inner frame 10 is bent to form a limiting structure 11 that abuts against the backlight surface of the laminate 1, and one end of the inner frame 10 is bent toward the backlight surface of the laminate 1, so as to be in contact with the backlight surface of the laminate 1, thereby effectively avoiding the displacement between the inner frame 10 and the side of the laminate 1, and increasing the contact area between the inner frame 10 and the laminate 1, thereby improving the stability of the connection between the inner frame 10 and the laminate 1. Accordingly, when the structure of the inner frame 10 is large enough, a first surface structure can be provided on the bottom surface of the structure after the inner frame 10 is bent, and connected to the outer frame 20.

[0053] Furthermore, in order to balance the stability of the matching connection between the first surface structure of the inner frame 10 and the second surface structure of the outer frame 20, as well as the simplicity of the preparation of the first surface structure and the second surface structure, one of the first surface structure and the second surface structure can be set as a surface protrusion structure, and the other can be set as a surface recessed structure that matches the surface protrusion structure.

[0054] It should be noted that in this embodiment, one of the first surface structure and the second surface structure is set as a surface protrusion structure, and the other is set as a surface depression structure, which ensures the simplicity of the preparation structure and the stability of the connection between the inner and outer frames. In this embodiment, a surface protrusion structure can be set on the first surface structure, and a corresponding surface depression structure can be set on the second surface structure; or a surface depression structure can be set on the first surface structure, and a corresponding surface protrusion structure can be set on the second surface structure.

[0055] Furthermore, in order to improve the convenience of preparation while ensuring that the first surface structure is firmly connected to the second surface structure, the surface protrusion structure can be set to at least one of a rib-shaped surface structure, a serrated surface structure and a convex dot surface structure.

[0056] In this embodiment, when the surface raised structure is set to at least one of a rib-shaped surface structure, a serrated surface structure and a convex dot-shaped surface structure, a corresponding surface recessed structure should be set to cooperate with the above structure, and it is necessary to ensure that the inner and outer frames 20 can be firmly connected under the influence of the external environment.

[0057] Furthermore, in order to avoid the phenomenon of stress accumulation between the inner frame and the laminate due to glue overflow, you can refer to Figure 3 , Figure 3 The schematic diagram of the structure of an inner frame in a photovoltaic module frame provided by an embodiment of the utility model. The inner frame 10 may be provided with a glue overflow hole 12; the glue overflow hole is a circular glue overflow hole.

[0058] It should be noted that, in this embodiment, by setting the overflow glue hole 12 in the inner frame 10, it is possible to prevent the overflow glue 2 of the laminate from being filled between the inner frame 10 and the side of the laminate 1, avoid the increase of stress between the inner frame 10 and the laminate 1, and improve the stability of the connection between the two. At the same time, the overflow glue 2 of the laminate overflows through the overflow glue hole 12 in the inner frame 10 to overflow between the inner frame 10 and the outer frame, and can be used as an adhesive to connect the inner frame 10 and the outer frame 20, thereby improving the stability of the connection between the inner and outer frames. By further setting the overflow glue hole 12 as a circular overflow glue hole, the overflow glue 2 of the laminate can be evenly dispersed on all sides of the circular overflow glue hole to avoid accumulation at the corners.

[0059] Furthermore, in order to improve the stability of the connection between the inner and outer frames, you can refer to Figure 4 , Figure 4 The first surface structure can be arranged on the same side where the inner frame 10 is connected to the laminate 1, and the first surface structure can be arranged on the lower side of the area where the inner frame 10 is connected to the laminate 1.

[0060] It should be noted that in this embodiment, a first surface structure is arranged on the side of the inner frame 10 close to the laminate 1, and at this time, the inner frame 10 extends downward from the bottom surface of the laminate 1, and the first surface structure is arranged on the part extending beyond the bottom surface of the laminate 1. This embodiment does not limit the specific way in which the outer frame 20 is connected to the inner frame 10. A recessed area can be arranged in the outer frame 20, and a second surface structure can be arranged on the surface of one side of the recessed area, so that the area of ​​the inner frame 10 where the first surface structure is arranged extends into the recessed area and realizes a concave-convex connection with the second surface structure. The photovoltaic module frame provided by the embodiment of the utility model includes an inner frame 10 and an outer frame 20; the inner frame 10 is fixedly connected to the side of the laminate 1 by lamination, and the inner frame 10 has a first surface structure connected to the outer frame 20; the outer frame 20 is used to carry the laminate 1 and the inner frame 10, and the outer frame 20 is provided with a second surface structure installed in cooperation with the first surface structure; after installation, the inner frame 10 and the outer frame 20 do not exceed the light-receiving surface of the laminate 1. The utility model arranges the inner frame 10 and the outer frame 20 so that they do not extend beyond the light-receiving surface of the laminate 1 after installation, thereby avoiding dust obstruction. At the same time, the inner frame 10 and the outer frame 20 are arranged to be installed on the side and the backlight surface of the laminate 1 through the first surface structure and the second surface structure to form a package, and the inner frame 10 is connected to the laminate 1 through lamination processing, thereby improving the stability of the connection.

[0061] In addition, the embodiment of the utility model is to set the above-mentioned inner frame 10 to be bent to form a limiting structure 11 that abuts against the backlight surface of the laminate 1, thereby effectively avoiding the displacement between the inner frame 10 and the side of the laminate 1, and at the same time increasing the contact area between the inner frame 10 and the laminate 1, thereby improving the stability of the connection between the inner frame 10 and the laminate 1; the first surface structure and the second surface structure are both set to include a surface protrusion structure and / or a surface depression structure, while ensuring the simplicity of the preparation structure, the stability of the connection between the inner and outer frames is ensured; by setting the above-mentioned first surface structure or the second surface structure to a surface structure formed by at least one of a rib-shaped surface structure, a serrated surface structure and a convex dot-shaped surface structure, while ensuring While the first surface structure is firmly connected to the second surface structure, the convenience of preparation is improved. By setting the overflow hole 12 in the inner frame 10, it is possible to avoid a large amount of overflow glue 2 from the laminate to be filled between the inner frame 10 and the side of the laminate 1, avoid increasing the stress between the inner frame 10 and the laminate 1, and improve the stability of the connection between the two. The overflow hole 12 is set as a circular overflow hole, which can further avoid stress accumulation at the corners of the overflow hole 12; the first surface structure is set on the side of the inner frame 10 close to the laminate 1, so as to avoid preparing the first surface structure on the side of the inner frame 10 facing away from the laminate 1, resulting in an uneven surface where the inner frame 10 contacts the laminate 1, thereby improving the fixing effect of the photovoltaic module frame on the laminate 1.

On the other hand, by providing the second overflow glue groove 25, the accommodation volume for the overflow glue 2 of the laminate can be increased, thereby preventing the overflow of the colloid.

[0072] Further, please refer to Figure 7 , Figure 7 A schematic diagram of the structure of the inner and outer frames of another photovoltaic module frame provided by an embodiment of the utility model.
