[0049] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0050] Reference Figure 1 , Figure 1 A cross-sectional schematic diagram of a first embodiment of a roof structure is shown. The roof structure includes: a photovoltaic tile 10, a base support 20, and a tile hanger 30. The tile hanger 30 includes: a mounting portion 31 and two fixing portions 32 respectively arranged on opposite sides of the mounting portion 31. The fixing portions 32 are used for fixed connection with the roof surface 40. The side of the photovoltaic tile 10 facing the roof surface 40 is fixedly connected to the base support 20. The mounting portion 31 is used for mating connection with the base support 20 of the photovoltaic tile 10. Preferably, the side of the photovoltaic tile 10 facing the roof surface 40 is fixedly connected to the base support 20.

[0051] Optionally, roof 40 is a sloping roof.

[0052] In this embodiment of the invention, the roof 40 may be a sloping roof. Figure 1The roof 40 shown is a sloping roof (or a horizontal roof). The roof structure can be a sandwich panel, cement roof panel, or other roof structural layers. Photovoltaic cells can be embedded inside the photovoltaic tiles. Both sides of the photovoltaic tiles can be covered with a glass layer, or only the light-facing side can be covered with a glass layer. In addition to fulfilling the basic functions of roof tiles, photovoltaic tiles can further realize photovoltaic power generation. Specifically, in this embodiment, the tile hanger 30 is fixedly mounted on the roof 40 by the fixing part 32, and the hanging part 31 of the tile hanger 30 supports and fixes the base support 20. The base support 20 then connects and fixes the ends of the photovoltaic tiles 10, thereby fixing the photovoltaic tiles 10 to the roof 40. When the individual photovoltaic tiles are spliced ​​together... Figure 1 The photovoltaic tiles are spliced ​​together or overlapped to form an integral roof structure.

[0053] Furthermore, Figure 1 The tile hanger 30 shown can be used to support and connect the ends of two adjacent photovoltaic tiles 10. Specifically, the tile hanger 30 includes: a mounting part 31 and two fixing parts 32 respectively arranged on opposite sides of the mounting part 31; the fixing parts 32 are used to fix the connection with the roof 40. In one implementation, self-tapping screws 321 can be used to drive into the fixing parts 32 and the roof 40 to complete the fixed connection between the tile hanger 30 and the roof 40.

[0054] In this design, the side of the photovoltaic tile 10 facing the roof 40 can be pre-fixed to the base support 20 to form an assembly. Subsequently, the pre-assembled base support 20 on the photovoltaic tile 10 can connect with the mounting part to form a tile hanger 30 that supports and fixes the photovoltaic tile 10. Furthermore, the pre-fitting connection between the base support and the tile hanger further improves assembly efficiency while ensuring connection stability.

[0055] Optional, refer to Figure 1 A mounting part 31 is disposed between adjacent photovoltaic tiles 10. The mounting part 31 is used to connect with the base support 20 on the first side of one photovoltaic tile 10 and the base support 20 on the second side of another photovoltaic tile 10 respectively, with the first side facing the second side.

[0056] In this embodiment of the present invention, the first side of the photovoltaic tile 10 in one assembly can be connected to the mounting part 31 by the base 20 provided on the first side, and the second side of the photovoltaic tile 10 in another adjacent assembly can be connected to the mounting part 31 by the base 20 provided on the second side, thereby forming a tile hanger 30 to support and fix the two adjacent photovoltaic tiles 10.

[0057] In this embodiment of the utility model, the process of assembling the roof structure mainly includes: first, fixing the tile hanger 30 to the roof 40; then, obtaining the assembly obtained by pre-assembling the photovoltaic tile 10 and the base support 20; finally, fixing the photovoltaic tile 10 in the assembly to the tile hanger 30 through the base support 20; and repeating this process to form the roof structure.

[0058] In summary, the roof structure provided by this utility model allows photovoltaic tiles to form a mating connection with the mounting part of the tile hanger through a set base, avoiding the need for drilling and bolting. This mating connection reduces assembly complexity and improves assembly efficiency while ensuring connection stability. In addition, the mating connection between the photovoltaic tiles and the mounting part of the tile hanger through the base avoids the lower end of the photovoltaic tile relying solely on gravity to overlap with adjacent photovoltaic tiles, thus improving the connection stability between tiles and between tiles and the roof.

[0059] Optional, refer to Figure 1 and Figure 2 , Figure 2 A cross-sectional structural schematic diagram of a second embodiment of a roof structure is shown. The mounting part 31 includes a contact part 311 for contacting the roof, a support plate 312, and a limiting part 313.

[0060] In the first and second embodiments of this utility model, self-tapping screws 321 can be used to drive the fixing part 32 and the roof 40 to complete the fixed connection between the tile hanger 30 and the roof 40. The contact part 311 is used to contact the roof 40 and increase the setting height of the support plate 312 connected to it, so that the support plate 312 can be at a certain height from the roof and has a horizontal bearing function. The bottom support 20 of the photovoltaic tile 10 can be supported on the support plate 312. Furthermore, a limiting part 313 can also be provided on the contact part 311 and the support plate 312. The limiting part 313 is mainly used to achieve structural matching with the mating part on the bottom support 20, so that the bottom support 20 can form a mating connection with the limiting part 313. This mating connection method avoids the drilling connection operation such as nailing and bolting. The mating connection reduces the assembly complexity while ensuring the connection stability.

[0061] Furthermore, the structure of the base support 20 can be matched with the structure of the mounting part 31 of the tile hanger 30.

The mating part 23 is provided on the second plate 22, and the mating part 23 can be used to cooperate and connect with the limiting part 313 on the tile hanger 30.

[0064] In the first embodiment of this utility model, the contact portion 311 includes: a first horizontal plate a, a first vertical plate b, a second vertical plate c, and a third vertical plate d. The first horizontal plate a directly contacts the roof 40, while the first vertical plates b, c, and d provide support and raise the height of the supporting plate 312.

Moreover, the entire assembly process is relatively simple and efficient.

[0081] It should be noted that, referring to Figure 2 The end of the side of the taller support plate 312 in the roof mounting bracket 30 facing the roof can be chamfered. This reduces the risk of impact damage to the sun-receiving surface of the photovoltaic tile 10 caused by the taller support plate 312 during assembly. Alternatively, the shorter support plate 312 in the roof mounting bracket 30 can form an angle with the roof 40 to meet the overlapping requirements of the photovoltaic tiles.

[0082] In summary, the assembly process of the roof structure (sloping roof) of the second embodiment of this utility model is described as follows:

[0083] 1. Reference Figure 8 First, self-tapping screws 321 can be used to nail the fixing part 32 of the tile hanger 30 and the roof 40 respectively to complete the fixed connection between the tile hanger 30 and the roof 40.

[0084] 2. Reference Figure 9Then, the bottom support 20 of the photovoltaic tile 10 can be tilted and placed on the support plate 312 with a lower setting height of the tile hanger 30, and pushed along the ridge direction x to ensure that the bottom support 20 of the upper end of the photovoltaic tile 10 (the end closer to the ridge direction x) reaches position p1, and that the bottom support 20 of the lower end of the photovoltaic tile 10 (the end closer to the purlin direction y) is separated from the corresponding tile hanger 30.

[0085] 3. Reference Figure 10 Then, the photovoltaic tile 10 can be pushed up so that the bottom support 20 at the upper end of the photovoltaic tile 10 (the end closest to the ridge x direction) reaches position p2. Then, the posture of the photovoltaic tile 10 is adjusted so that the bottom support 20 at the lower end of the photovoltaic tile 10 can be placed on the support plate 312 with a higher setting height of the corresponding tile hanging piece 30. During this process, the waterproof strip 50 is in a lifted state.

[0086] 4. Reference Figure 11 Then, gravity can be used to slide the photovoltaic tile 10 down, so that the bottom support 20 at the upper end of the photovoltaic tile 10 reaches position p3, and the limiting strip 232 of the bottom support 20 at the upper end of the photovoltaic tile 10 fits into the limiting groove g. At the same time, the bottom support 20 at the lower end of the photovoltaic tile 10 is connected to the fifth anti-detachment hook o of the corresponding tile hanging piece 30, and the pressure on the waterproof strip 50 is evenly distributed to achieve a waterproof effect. This completes the installation of one photovoltaic tile. Repeating the above process can form a series of photovoltaic tiles. Figure 2 and Figure 12 The roof structure shown. Figure 12 This diagram illustrates the short-side installation and splicing of the photovoltaic tiles in the second embodiment of this invention. Figure 2 The diagram shown is a schematic diagram of the long side installation and splicing of the photovoltaic tile in the second embodiment of this utility model.

[0087] In summary, the roof structure provided by this utility model allows photovoltaic tiles to connect with the mounting parts of the tile hangers via a base support, avoiding the need for nailing and bolting. This connection ensures stability while reducing assembly complexity and improving efficiency. Furthermore, the connection between the base support and the mounting parts prevents the lower ends of the photovoltaic tiles from relying solely on gravity to overlap with adjacent tiles, thus enhancing the stability of connections between tiles and between tiles and the roof. Additionally, each photovoltaic tile is reliably connected to the batten strip at both ends, preventing direct connection between adjacent tiles and ensuring independent installation and removal of any single tile.
