[0007] The aerated gel includes a filling portion and a first buffer portion. The filling portion is disposed inside the accommodating space, and the first buffer portion is disposed at the first end of the filling portion. The first buffer portion protrudes from the opening of the accommodating space and is configured to abut against the photovoltaic layer.

[0008] Optionally, the accommodating space is provided with openings at both ends, and the aerated gel also includes a second buffer portion, which is symmetrically disposed at the second end of the filling portion relative to the first buffer portion, and the second buffer portion is configured to abut against the backing layer.

[0009] Optionally, the intermediate layer is fitted with a first frame, and the top surface of the four sides of the first frame is provided with receiving grooves. A partition is provided in the receiving groove, and the partition is configured to divide the internal space of the receiving groove into a first space and a second space. A rubber pad is provided in the first space.

[0010] Optionally, the photovoltaic layer is fitted with a second frame, and the bottom surface of the four sides of the second frame is provided with limiting protrusions and limiting plates. The limiting protrusions are located in the first space and abut against the rubber pad, and the limiting plates are located in the second space.

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model belongs.

[0025] Please see Figures 1 to 5 As shown, this embodiment provides a photovoltaic tile, which includes a photovoltaic layer 10, an intermediate layer 20 and a backsheet layer 30 arranged sequentially from top to bottom. The intermediate layer 20 includes a plurality of neatly arranged regular hexagonal aluminum honeycomb cores 21. The interior of the aluminum honeycomb cores 21 is provided with a accommodating space 22 in the vertical direction. At least one end of the accommodating space 22 is open. An aerated gel 23 is disposed inside the accommodating space 22. The aerated gel 23 includes a filling part 230 and a first buffer part 231. The filling part 230 is disposed inside the accommodating space 22. The first buffer part 231 is disposed at the first end of the filling part 230 and protrudes from the opening of the accommodating space 22. The first buffer part 231 is configured to abut against the photovoltaic layer 10.

[0026] As can be seen, the intermediate layer 20 adopts a regular hexagonal aluminum honeycomb core 21 structure. Utilizing the principle of honeycomb mechanics, it is lightweight while possessing high compressive strength. Together with the first buffer part 231, it can withstand roof loads and external impacts, reducing the deformation of photovoltaic tiles caused by their own weight or external forces.

[0027] In one embodiment, the accommodating space 22 has openings at both ends, and the aerated gel 23 also includes a second buffer portion 232. The second buffer portion 232 is symmetrically disposed at the second end of the filling portion 230 relative to the first buffer portion 231, and the second buffer portion 232 is configured to abut against the backing layer 30.

[0028] As can be seen, the accommodating space 22 has openings at both ends and is provided with symmetrical first buffer part 231 and second buffer part 232, which respectively abut against the photovoltaic layer 10 and the back sheet layer 30, forming a bidirectional buffer structure. When the tile is subjected to vertical compression or vibration, the bidirectional buffer can distribute the force evenly, preventing the photovoltaic layer 10 or the back sheet layer 30 from being damaged due to excessive unidirectional force.

[0029] In one embodiment, the intermediate layer 20 is provided with a first frame 24, and the top surface of the four sides of the first frame 24 is provided with a receiving groove. A partition 241 is provided in the receiving groove. The partition 241 is configured to divide the internal space of the receiving groove into a first space 242 and a second space 243. A rubber pad is provided in the first space 242.

[0030] As can be seen, a partition 241 and a rubber pad are provided in the receiving groove of the first frame 24. The rubber pad buffers the impact or compression on the edge of the tile through elastic deformation, and at the same time fills the edge gap to prevent rainwater and dust from seeping into the interior of the tile from the edge.

[0031] In one embodiment, the photovoltaic layer 10 is provided with a second frame 11. The bottom surface of the four sides of the second frame 11 is provided with limiting protrusions 12 and limiting plates 13. The limiting protrusions 12 are disposed in the first space 242 and abut against the rubber pad. The limiting plates 13 are disposed in the second space 243. The limiting plates 13 are configured to at least prevent liquid from entering the interior of the photovoltaic tile.

[0032] As can be seen, the limiting protrusion 12 of the second frame 11 abuts against the rubber pad, which not only achieves edge buffering through the elasticity of the rubber pad, but also restricts the lateral displacement of the tile through the cooperation between the limiting protrusion 12 and the first space 242, ensuring that the position is fixed after installation.

[0033] In one embodiment, the back panel layer 30 is fitted with a third frame 31, the top surface of the third frame 31 is provided with a rubber layer 32, and the top surfaces of the four sides of the third frame 31 are provided with a plurality of mounting holes 33 spaced apart. A spring 34 is provided in the mounting hole 33, the first end of the spring 34 is fixedly installed in the mounting hole 33, and the second end of the spring 34 passes through the rubber layer 32 and abuts against the bottom surface of the intermediate layer 20.

[0034] As can be seen, the third frame 31 of the back sheet layer 30 abuts against the bottom surface of the intermediate layer 20 through the spring 34. When the tile expands and contracts due to temperature changes or is subjected to external vibration, the elastic deformation of the spring 34 can absorb energy, reduce stress concentration between layers, and prevent the back sheet layer 30 from cracking or the photovoltaic layer 10 from falling off.

[0035] In one embodiment, the photovoltaic layer 10, the intermediate layer 20 and the backsheet layer 30 are provided with PVDF coatings on their sides.

[0036] It is evident that the PVDF coating on the edges has excellent resistance to ultraviolet radiation, weathering, and chemical corrosion, which can prevent the edges of the tiles from aging, fading, cracking, and other problems caused by long-term exposure to the outdoor environment, thus extending the service life of the tiles.

[0037] In the embodiments disclosed in this utility model, the terms "installation," "connection," "linking," and "fixing" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; "linking" can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments disclosed in this utility model according to the specific circumstances.

[0038] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above examples. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
