[0002] In solar photovoltaic modules, the laminate including the solar panels is sealed and fixed by the frame. The function of the frame is to enhance the mechanical strength of the module, seal the edges of the module laminate, and fix the module to the fixing frame through the frame.

[0003] In the existing installation process, securing the frame to the mounting bracket is a complex process requiring multiple fasteners, each of which needs to be inserted into the side grooves of the profile. Because its width is larger than the spacing between PV modules, when removing the central clamp of the PV array, even if the fasteners between the module and the clamp are loosened, it is difficult to remove it from the top. The clamp or clamp assembly can only be slid out along the frame. However, the gaps between PV modules are not uniform and may even deform under load. This makes sliding the clamp or clamp assembly along the frame inconvenient or even impossible, making removal and replacement difficult.

[0018] Figure 1 It is a structural diagram of the present utility model. DETAILED DESCRIPTION

However, it should be understood that the drawings are for illustrative purposes only and are not to be construed as limiting this patent.

For those skilled in the art, it is understandable that some well-known structures and their descriptions may be omitted in the drawings. The positional relationships described in the drawings are for illustrative purposes only and are not to be construed as limiting this patent.

[0020] like Figure 1 As shown, the utility model provides a composite material photovoltaic frame profile structure and fixing structure, including a profile 1 constituting a frame and a fixing assembly for fixing the profile 1 to a fixing frame, the fixing assembly including a first bead 2 and a second bead 3 abutting against the profile 1, the profile 1 is provided with an inlay cavity 11 for inlaying solar panels, and the opening direction of the inlay cavity 11 is defined as the inner side of the profile 1; the first bead 2 is located on the outer side of the profile 1, and the first bead 2 limits the position of the profile 1 in the vertical direction, and the second bead 3 is located on the inner side of the profile 1, and the second bead 3 limits the position of the profile 1 in the horizontal direction.

[0021] The present application uses a profile 1 to form a frame for accommodating a solar panel, and then fixes the solar panel to the fixing frame by fixing the profile 1 to the first bead 2 and the second bead 3 on the fixing frame. The fixing method is simple and reliable. By connecting the first bead 2 and the second bead 3 on the fixing frame, the frame formed by the profile 1 is limited in the vertical and horizontal directions respectively, thereby ensuring that the solar panel can be fixed on the fixing frame, which can reduce the installation difficulty and production cost and improve the installation efficiency.

[0022] The first pressing strip 2 abuts against the side surface of the profile 1 , and the profile 1 is provided with a first pressing portion 21 on the abutting surface with the profile 1 , and the bottom surface of the first pressing portion 21 abuts against the top of the profile 1 .

[0023] When the first pressing strip 2 limits the profile 1, the profile 1 cannot move in the vertical direction under the action of the first pressing part 21, and the profile 1 cannot move in the horizontal direction towards the first pressing strip 2 because the first pressing strip 2 abuts against the side surface of the profile 1. Therefore, when the profile 1 forms a frame, the outer side of each profile 1 has the first pressing strip 2 for fixation, and all the first pressing strips 2 cooperate to ensure that the frame cannot move in the horizontal direction and the vertical direction, thereby achieving a good fixation effect.

[0024] Further, the second pressing strip 3 is provided with a second pressing part 32, the bottom surface of the second pressing part 32 abutting against the top surface of the first bottom plate 12 of the profile 1; one of the second pressing part 32 and the first bottom plate 12 is provided with a limiting groove 41, and the other is provided with a limiting strip 42, and the limiting strip 42 is embedded in the limiting groove 41.

[0025] The second pressing part 32 limits the first bottom plate 12 of the profile 1 in the vertical direction, thereby achieving a better limiting effect on the profile 1.

[0026] Through the cooperation of the limiting groove 31 and the limiting strip 32, the movement of the profile 1 in the horizontal direction can be further limited, and the limiting effect of the second pressing strip 3 on the profile 1 can be better achieved.

[0027] In the present application, the profile 1 comprises a first bottom plate 12, the first bottom plate 12 is provided with a first vertical plate 13 and a second vertical plate 14 located inside the first vertical plate 13, and the first bottom plate 12 is further provided with a limiting groove 41 or a limiting strip 42 in the area inside the second vertical plate 14; the top of the second vertical plate 14 is connected with a first horizontal plate 15, and the first horizontal plate 15 is further connected to the first vertical plate 13; the first vertical plate 13 is further connected with a second horizontal plate 16, the second horizontal plate 16 is located above the first horizontal plate 15, and at least part of the second horizontal plate 16 is located inside the first vertical plate 13; the area inside the second vertical plate 14 surrounded by the first horizontal plate 15, the first vertical plate 13 and the second horizontal plate 16 is a inlay cavity 11.

[0028] The inlay cavity 11 is used for embedding a solar panel.

[0029] The second horizontal plate 16 is provided with a sealing groove 17 for embedding a sealing member on the bottom surface inside the first vertical plate 13.

[0030] Embedding the sealing member in the sealing groove 17 can ensure that the profile 1 and the solar panel have good sealing performance, so that liquid cannot flow into the connection between the profile 1 and the solar panel to cause the solar panel to fail to work normally.

[0031] The top surface of the first bottom plate 12 and the bottom surface of the first horizontal plate 15 are both connected with a support strip 18, and the support strip 18 is located inside the first vertical plate 13.

[0032] Due to the limitation of the process, the connecting part of the first vertical plate 13, the second vertical plate 14 and the first horizontal plate 15, the first bottom plate 12 will generate a round corner, by setting the support strip on the first horizontal plate 15 and the first bottom plate 12, it is convenient for other structures to be better embedded between the first horizontal plate 15 and the first bottom plate 12, so as to ensure that a better connecting effect can be realized.

[0033] The first pressing strip 2 comprises a second bottom plate 22, the second bottom plate 22 is provided with at least one third vertical plate 23 for abutting with the side surface of the profile 1, and the first pressing part 21 is connected to the abutting surface of the third vertical plate 23 and the side surface of the profile 1.

[0034] The second bottom plate 22 of the first pressing strip 2 is further provided with a through hole for passing through a bolt, and the bolt is connected to the fixing frame after passing through the through hole; in order to facilitate fixation, the bolt is selected as an internal hexagonal bolt.

[0035] In the embodiment, the number of the third vertical plate 23 is two, that is, one first pressing strip 2 can simultaneously limit two profiles 1, the structure is simplified, and the production cost is reduced.

[0036] The second pressing strip 3 comprises a third bottom plate 31, the third bottom plate 31 is connected with a second pressing part 32, and the bottom surface of the second pressing part 32 is provided with a limiting groove 41 or a limiting strip 42.

[0037] Through the cooperation of the limiting groove 41 and the limiting strip 42, the limiting ability of the second pressing strip 3 to the profile 1 in the horizontal direction is improved.

[0038] In the embodiment, the inner side end of the first bottom plate 12 is provided with a limiting strip 42, and the second pressing part 32 is provided with a limiting groove 41, so that the profile 1 has sufficient structural strength, and the profile 1 has good supporting properties after installation.

[0040] The second pressing part 32 is located at one end of the third bottom plate 31, and at least part of the bottom surface of the third bottom plate 31 is lower than the bottom surface of the second pressing part 32. Even if the second pressing strip 3 or the profile 1 has a slight deformation during the fixing process, part of the bottom surface of the second pressing part 32 can also abut on the first bottom plate 12, so that the second pressing strip 3 can better limit the profile 1 in the vertical direction.
