Description

Technical Field

[0001] This utility model belongs to the field of building decoration and photovoltaic application technology, specifically, it relates to a photovoltaic tile-like structure. Background Technology

[0002] Existing photovoltaic roof systems suffer from the following technical drawbacks: Traditional photovoltaic modules require additional brackets for installation on the roof, increasing the roof load; the brackets penetrating the roof can damage the waterproofing structure, increasing the risk of leakage; photovoltaic modules and metal roofs require separate construction, involving multiple processes such as bracket welding and cable laying; additionally, specialized edge-locking machines are needed for mechanical edge locking, making the installation process complex; traditional metal panels are fixed with exposed screws or simple overlaps, which can easily lead to leaks after the fixing points rust, and gaps can form at the joints due to thermal expansion and contraction, resulting in poor durability; exposed photovoltaic brackets and cables are susceptible to corrosion, leading to high annual maintenance costs in coastal areas, and replacing modules requires dismantling the roof structure, posing a high risk of secondary damage; exposed fasteners and joints also compromise the integrity of the building facade, resulting in insufficient aesthetics.

[0003] To address the aforementioned issues, this utility model integrates a metal panel and photovoltaic tile design, combined with a double-folded self-locking structure and concealed installation technology, to achieve easy roof installation and photovoltaic power generation, thus breaking through the technical bottlenecks of existing photovoltaic roof systems. Utility Model Content

[0004] The purpose of this utility model is to provide a photovoltaic tile-like structure. Compared with the prior art, this technical solution mainly solves the problems of disconnection between photovoltaic modules and metal roof installation, poor waterproof performance, complex procedures and high maintenance costs in existing photovoltaic roof systems. It provides a hidden upright locking structure that integrates photovoltaic tiles and metal panels, achieving rapid installation, long-lasting waterproofing and high-efficiency power generation of photovoltaic tile metal panels.

[0005] To solve the above problems, this utility model adopts the following technical solution: a photovoltaic tile-like structure, including a self-locking buckle assembly, a fixing bracket, and a photovoltaic tile; the self-locking buckle assembly includes a panel body, and male and female buckle edges extending along the two sides of the panel body respectively, the male and female buckle edges being a double-folded edge connection structure that can cooperate with each other to achieve mechanical self-locking; the fixing bracket is connected to the self-locking buckle assembly through a hanging structure to position and fix the self-locking buckle assembly to the building base, and the fixing bracket as a whole is not exposed on the upper surface of the panel body; the photovoltaic tile is fixed to the upper surface of the panel body and forms an electrical connection structure that is not exposed on the surface of the photovoltaic tile to realize power output.

[0006] Furthermore, the double-folded structure of the male and female fastening edges has the same height, which is 30mm-50mm.

[0007] Furthermore, the double-folded edge connection structure of the male fastener includes: a first folded edge extending perpendicularly to the surface of the panel body, and a first mating portion bent from the top of the first folded edge toward the panel body; the double-folded edge connection structure of the female fastener includes: a second folded edge extending perpendicularly to the surface of the panel body, and a second mating portion bent from the top of the second folded edge toward a direction away from the panel body, wherein the first mating portion and the second mating portion are shape-matched to achieve mechanical self-locking.

[0008] Furthermore, the first mating part is an L-shaped extended tongue, and the second mating part is a V-shaped protrusion, with a 0.3mm-0.5mm gap reserved between the V-shaped protrusion and the L-shaped extended tongue.

[0009] Furthermore, the fixing bracket includes a horizontal part fixed to the building base and a vertical part connected to the male buckle edge of the self-locking buckle plate assembly via a hook-up structure; the hook-up structure is a bent part located at the edge of the vertical part and facing the direction of the male buckle edge.

[0010] Furthermore, the horizontal section is provided with a positioning structure to ensure that the adjacent panel bodies are installed flush.

[0011] Furthermore, the positioning structure includes positioning wings symmetrically arranged on both sides of the vertical part. The positioning wing facing the female buckle edge is provided with screw holes and positioning bosses flush with the screw heads; the positioning wing facing the male buckle edge is provided with protrusions to ensure that the adjacent panel bodies are flush.

[0012] Furthermore, the effective width of the self-locking buckle assembly is 300mm-600mm, the thickness of the panel body is 0.8-1.2mm, and it is made of aluminum-magnesium-manganese alloy, aluminum-zinc plated or titanium-zinc material.

[0013] Furthermore, the photovoltaic tile is fixed to the upper surface of the panel body by an adhesive, and the electrical connection structure includes a through hole that penetrates the panel body. The power cable of the photovoltaic tile extends through the through hole to the power input end of the adjacent photovoltaic tile, thereby realizing the series electrical connection of the adjacent photovoltaic tiles.

[0014] Furthermore, the male and female buckle edges are provided with arc transition sections at their ends along the length direction, and the arc transition sections are reserved with foldable extensions.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. In terms of installation efficiency and convenience, its core advantage stems from the double-folded mechanical self-locking design of the male and female fasteners: through the precise cooperation of the L-shaped extended tongue and V-shaped protrusion, coupled with a reserved gap of 0.3 to 0.5 mm, adjacent panels can be quickly spliced ​​by simply pressing manually. No special edge-locking equipment is required throughout the process, greatly simplifying the complex process of traditional photovoltaic roof systems that rely on mechanical edge-locking. The fixing bracket adopts a concealed installation scheme, which is fixed to the building base with two screws on the horizontal part. The vertical bending structure is hidden under the panel after being hooked with the male fastener, which not only avoids the risk of corrosion of exposed fasteners, but also reduces secondary damage to the roof waterproofing structure during installation.

[0016] 2. Synergistic optimization of materials and structural design further enhances system performance: The main panel body uses aluminum-magnesium-manganese alloy, aluminum-zinc plating, or titanium-zinc plating, with a thickness controlled between 0.8 and 1.2 mm, significantly reducing roof load while ensuring structural strength; the double-folded edge structure has a uniform height of 30 to 50 mm, combined with the rounded transition section at the ends and a 4 cm foldable extension, effectively eliminating gaps caused by thermal expansion and contraction at the joints, resulting in significantly improved waterproof performance compared to traditional overlapping panels. The design of the positioning wings and protrusions ensures that adjacent panels are coplanar after installation, with flatness errors controlled within 0.5 mm, providing a stable foundation for subsequent photovoltaic tile installation.

[0017] 3. The integrated design of photovoltaic tiles and metal panels is another major highlight: the photovoltaic tiles are directly adhered to the surface of the panel body using adhesive, and the power cables are concealed and connected in series through pre-set wiring holes, avoiding the corrosion problems of traditional exposed cables and truly achieving efficient integration that generates electricity upon installation. The effective width of the self-locking panel assembly can be adjusted within the range of 300 to 600 mm, with 380 mm being the optimal choice in practical applications. It can be customized according to the roof length, significantly reducing the number of seams; combined with concealed fasteners and a smooth photovoltaic tile surface, the overall integrity and aesthetics of the building facade are significantly improved.

[0018] 4. The structure is equally outstanding in terms of versatility and economy: it has the dual functions of roof decoration and photovoltaic power generation, and can be used for new buildings as well as old roof renovation needs; in the corrosive environment of high humidity and high salinity in the coastal area, the anti-corrosion properties of the alloy material and the concealed structure design work together to greatly extend the service life of the system and significantly reduce the average annual maintenance cost compared with traditional solutions.

Therefore, they should not be construed as limitations on this utility model.

[0024] The present invention will be further described below with reference to specific embodiments.

[0025] This utility model provides a photovoltaic tile structure, including a self-locking buckle assembly, a fixing bracket, and a photovoltaic tile 4. The self-locking buckle assembly includes a panel body 1, and male buckle edge 2 and female buckle edge 3 extending along the two sides of the panel body 1, respectively. The male buckle edge 2 and female buckle edge 3 are a double-folded edge connection structure that can cooperate with each other to achieve mechanical self-locking. The fixing bracket is connected to the self-locking buckle assembly through a hanging structure to position and fix the self-locking buckle assembly to the building base, and the fixing bracket as a whole is not exposed on the upper surface of the panel body 1. The photovoltaic tile 4 is fixed to the upper surface of the panel body 1 and forms an electrical connection structure that is not exposed on the surface of the photovoltaic tile 4 to realize power output.

[0026] Preferably, the panel body 1 is made of aluminum-magnesium-manganese alloy, aluminum-zinc plating or titanium-zinc material, with a thickness of 0.8-1.2mm, preferably 0.8mm; an effective width of 300-600mm, preferably 380mm; and a rib height of 30-50mm, preferably 35mm, to improve wind resistance.

[0027] Preferably, the male buckle edge 2 and the female buckle edge 3 on both sides have a double-folded edge connection structure: the male buckle edge 2 is provided with a first folded edge 5 and an L-shaped extension tongue, and the female buckle edge 3 is provided with a second folded edge 7 and a V-shaped protrusion. The two are matched in shape and a gap of 0.3-0.5mm is reserved. Pressing it will mechanically lock it.

[0028] Preferably, the ends of the male buckle edge 2 and the female buckle edge 3 along the length direction are provided with arc transition sections 14 (crescent-shaped openings). The arc transition sections 14 are reserved with a foldable 4cm extension 15, which can be folded over to seal the joint during installation, further improving waterproofness.

[0029] Preferably, the fixing bracket includes a horizontal part that is fixed to the batten strip and a vertical part that is hooked to the male buckle edge 2. The hooking structure is a bent part 9 at the edge of the vertical part. The horizontal part is equipped with positioning wings 10: the positioning wings 10 on the female buckle edge 3 side have screw holes 11 and positioning bosses 12, which are flush with the nail heads; the positioning wings 10 on the male buckle edge 2 side have protrusions 13 to ensure that adjacent panels are coplanar and the flatness error is ≤0.5mm.

[0030] Preferably, the photovoltaic tile 4 is fixed to the upper surface of the panel body 1 by an adhesive; the panel body 1 is provided with a wire hole, and the power cable of the photovoltaic tile 4 extends through the wire hole to the input end of the adjacent photovoltaic tile 4 to achieve hidden series connection and avoid the cable exposure and corrosion.

[0031] The working principle of this utility model is as follows: For old roof renovations, the original damaged tiles must first be removed and the base layer cleaned before laying battens as the installation foundation. For new roofs, the installation can proceed directly to the mounting bracket fixing process. The mounting brackets are connected to the building base (such as battens) through the pre-set screw holes 11 on the horizontal part. The two-point screw fixing design ensures installation stability. The positioning wing 10 facing the female buckle edge 3 has a positioning boss 12, which makes the screw head flush with the surface of the bracket. The bent part 9 on the vertical edge engages with the male buckle edge 2 of the self-locking buckle panel assembly to achieve the initial positioning of the panel body 1. The protrusion 13 of the positioning wing 10 cooperates with the adjacent panels to ensure that multiple panels are installed flush, with the error controlled within the mm level.

[0032] The panel splicing process utilizes a double-folded mechanical self-locking structure of the male snap-fit ​​edge 2 and the female snap-fit ​​edge 3 for efficient installation. The top of the first folded edge 5 of the male snap-fit ​​edge 2 bends towards the panel body 1 to form an L-shaped extension tongue, while the top of the second folded edge 7 of the female snap-fit ​​edge 3 bends away from the panel body 1 to form a V-shaped protrusion. The two shapes are matched and a 0.3 to 0.5 mm elastic gap is reserved. During installation, the male snap-fit ​​edge 2 of one panel is first attached to the bent part 9 of the fixing bracket. Then, the female snap-fit ​​edge 3 of the adjacent panel is aligned with the male snap-fit ​​edge 2, and manual pressing allows the L-shaped tongue to embed into the V-shaped protrusion. The elastic deformation of the metal material achieves a tight fit, eliminating the need for special edge-locking equipment. Notably, the ends of both the male snap-fit ​​edge 2 and the female snap-fit ​​edge 3 are pre-made with arc transition sections 14 (crescent-shaped openings) and a 4 cm long extension 15 is reserved. After splicing, the extension 15 is folded and pressed together to further seal the joint and improve the overall waterproof performance.

[0033] The integrated photovoltaic tile 4 and the metal panel are achieved through adhesive bonding and concealed electrical connections: the photovoltaic tile 4 is directly fixed to the upper surface of the panel body 1 using high-strength structural adhesive, avoiding the penetration damage to the panel caused by traditional mechanical fixing; the panel body 1 has pre-set wiring holes, through which the output cables of the photovoltaic tile 4 extend to the power input terminals of adjacent photovoltaic tiles 4, forming a series circuit. The entire electrical connection structure is completely hidden beneath the photovoltaic tile 4, effectively preventing corrosion of the cables by the external environment. It should be noted that the materials, optical design, and junction box on the photovoltaic tile 4 are all existing technologies and are not the innovations of this utility model, and will not be explained in detail here. Through the above design, the fixed brackets and self-locking structure together form a concealed waterproof system. The absence of exposed fasteners reduces the risk of corrosion and leakage. The double-folded self-locking and the end folded extension 15 form multiple seals. The metal panel is made of aluminum-magnesium-manganese alloy, aluminum-zinc plating, or titanium-zinc material with a thickness of 0.8-1.2mm. It has both lightweight and high strength characteristics, reducing the roof load while improving corrosion resistance. The integrated design of the photovoltaic tile 4 and the panel enables power generation upon installation. With a customized effective width of 300-600mm (preferably 380mm), the number of seams is reduced, ultimately forming a photovoltaic roof / wall system that combines ease of installation, structural durability, and overall aesthetics.

[0034] In one embodiment, to further enhance the thermal insulation performance of the structure, reinforcing the bottom of the panel with insulation material or insulation structure is still within the scope of protection of this invention.

[0035] In one embodiment, the distance between the edge of the photovoltaic tile 4 and the edge of the panel body 1 is ≥50mm, and the self-locking buckle assembly can be customized according to the length of the building roof or wall, with a length of up to 12m.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
