In addition, the terms "first", "second", and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

[0029] The following combination Figure 2 The frame structure of the present invention is described as being disposed on the peripheral side of the laminate 100 .

[0030] like Figure 2 As shown, the first embodiment of the present invention provides a frame structure, including a first end 1, a second end 2 and a connecting portion 3 arranged between the first end 1 and the second end 2, and the first end 1 and the second end 2 are arranged opposite to each other.

[0031] Connecting portion 3 is formed only on one side of first end 1 and second end 2. This arrangement creates a semi-enclosed structure formed by the bottom side of first end 1, the top side of second end 2, and the inner side of connecting portion 3. One side of laminate 100 is embedded within the semi-enclosed structure; the top and bottom sides of laminate 100 are connected to first end 1 and second end 2, respectively. The top and bottom sides of laminate 100 refer to the side of laminate 100 closest to the ground when laminate 100 is horizontally placed, with the top side being the side opposite the bottom side.

[0032] The frame structure provided by the present invention is provided with a first end 1, a second end 2 and a connecting portion 3 provided between the first end 1 and the second end 2. The connecting portion 3 is only formed on one side of the first end 1 and the second end 2, and the bottom side of the first end 1, the top side of the second end 2 and the inner side of the connecting portion 3 form a semi-enclosed structure; one side of the laminate 100 is embedded in the interior of the semi-enclosed structure, and the top side and the bottom side of the laminate 100 are respectively connected to the first end 1 and the second end 2, which can effectively protect the components and reduce the damage rate of the components during transportation and installation. The frame structure is applied to the photovoltaic curtain wall components to effectively prevent water vapor and dust from entering and protect the internal structure of the components; in addition, it can also improve the wind load resistance of the photovoltaic curtain wall.

[0033] It can be understood that the longitudinal section of the frame structure is a C-shape that is symmetrical up and down, and the C-shaped opening is used for injecting glue to bond the laminate 100 .

[0034] In a feasible embodiment of the present invention, the first end 1 and the second end 2 are symmetrically arranged about a first plane, wherein the first plane is parallel to the plane of the laminate 100. In other words, the first end 1 and the second end 2 are equidistant from the plane of the laminate 100, and processing is facilitated.

[0035] In one possible embodiment of the present invention, a first positioning structure 4 is provided on a side of the first end 1 and the second end 2 away from the connection portion 3. The first positioning structure 4 extends toward the connection portion 3. That is, the first positioning structure 4 physically begins at the edge or surface of the first end 1 and the second end 2 and gradually unfolds or expands in a direction toward the connection portion 3. The first positioning structure 4 can contribute to the stability and rigidity of the entire structure, reducing the risk of deformation or damage when subjected to external loads or pressure. During the assembly process, the first positioning structure 4 may serve as a guiding or alignment aid, helping to ensure that the various components are assembled in the correct manner and sequence.

[0036] In a feasible embodiment of the present invention, a second positioning structure 5 is provided at the intersection of the first end 1 and the second end 2 with the connecting portion 3, and the second positioning structure 5 is bonded to the laminate 100; the second positioning structure 5 plays a role in strengthening connection, positioning or fixing.

[0037] There is a spacing distance between the first positioning structure 4 and the second positioning structure 5, that is, the first positioning structure 4 and the second positioning structure 5 are not directly connected or in contact, so that a first glue overflow groove 6 is formed between the first end 1, the first positioning structure 4 and the second positioning structure 5, and a second glue overflow groove 7 is formed between the second end 2, the first positioning structure 4 and the second positioning structure 5. The function of the first glue overflow groove 6 and the second glue overflow groove 7 is to accommodate excess glue or adhesive during the bonding process. When the adhesive is applied to the surface to be bonded, the overflowed glue may contaminate the surrounding area and affect the appearance or function. The first glue overflow groove 6 and the second glue overflow groove 7 provide a safe area to accommodate this excess glue, thereby maintaining the appearance of the photovoltaic curtain wall assembly.

[0038] Therefore, the provision of the first positioning structure 4 and the second positioning structure 5 and the first glue overflow groove 6 and the second glue overflow groove 7 not only helps to improve the stability and reliability of the entire structure, but also keeps the structure neat and beautiful.

[0039] In a feasible embodiment of the present invention, the connection portion, the first positioning structure 4 and the second positioning structure 5 are bonded to the laminate 100 by means of sealing silicone, rather than by angle brackets, and are more suitable for installation on photovoltaic curtain wall assemblies. Sealing silicone is a commonly used adhesive with good sealing performance, weather resistance and chemical corrosion resistance, and can maintain a stable bonding effect in various environments. Using sealing silicone for bonding can ensure that the connection between these structures and the laminate 100 is firm and reliable. Not using angle brackets for connection can simplify the complexity of the entire structure and the assembly process, and reduce manufacturing costs. Sealing silicone has excellent sealing performance and can effectively prevent external contaminants such as moisture and dust from entering the interior of the structure, thereby protecting internal components from damage.

[0040] In a feasible embodiment of the present invention, the extension length of the first end 1 from one side toward the connecting portion 3 to the other side is d, and 6mm<d<9mm. The extension length d of the first end 1 has a certain influence on the stability of the structure in which it is located. If d is too short, the structure may not be strong enough and may be easily deformed or damaged by external forces; if d is too long, the complexity and weight of the structure may be increased, and it is also not conducive to the rational use of space. Therefore, controlling d between 6mm and 9mm can avoid the occurrence of the above-mentioned adverse factors while ensuring the stability of the structure. Controlling the extension length d of the first end 1 within a certain range can also take into account the convenience of manufacturing and assembly. For example, during the manufacturing process, the accuracy of d can be ensured by precisely controlling the processing dimensions and tolerances; during the assembly process, the first end 1 can be more easily aligned and fixed with other components.

[0041] In a feasible embodiment of the present invention, the frame structure includes one of an aluminum frame, a steel frame, a composite material frame, and a plastic frame. Among them, the aluminum frame is light, strong, corrosion-resistant, aesthetically pleasing, and easy to process and recycle. The steel frame is strong, has a strong load-bearing capacity, is durable, and has excellent fire resistance. The composite material frame has excellent comprehensive performance and can be customized in terms of strength, weight, corrosion resistance, etc. according to requirements. The plastic frame is light, low-cost, easy to process, and easy to achieve complex shapes and colors.

[0042] In a feasible embodiment of the present invention, in a direction perpendicular to the plane of the laminate 100, the first end 1 and the second end 2 both protrude outward toward the side away from the laminate 100 to form an arc-shaped structure, thereby increasing the structural strength of the entire device, helping to resist the action of external forces, improving the overall durability and stability, and being able to increase the inner space of the first overflow glue groove 6 and the second overflow glue groove 7.

[0043] The second embodiment of the present invention is to provide a photovoltaic curtain wall assembly, including a laminate 100 and a frame structure as described in any of the above embodiments, and the frame structure is arranged on the long frame and the short frame of the laminate 100. The core part of the photovoltaic curtain wall assembly of the laminate 100 is usually composed of multiple layers of materials composited through a lamination process, and has excellent light transmittance, weather resistance and mechanical strength. The main function of the laminate is to protect the photovoltaic cells from damage by the external environment and effectively convert sunlight into electrical energy. The role of the frame structure is to enhance the structural strength of the photovoltaic curtain wall assembly, protect the edges of the laminate 100, and achieve connection and fixation with other components.

[0044] The third embodiment of the present invention provides a photovoltaic curtain wall, comprising the frame structure as described in any one of the above items or the photovoltaic curtain wall assembly as described above. The photovoltaic curtain wall is usually composed of multiple photovoltaic curtain wall assemblies.

[0045] The photovoltaic curtain wall assembly and photovoltaic curtain wall provided by the present invention have the various advantages as described above because they include the frame structure as described above.
