Specific implementation

[0044] In order to make the purpose, technical scheme and advantage of the utility model embodiment clearer, the technical scheme in the utility model embodiment will be described clearly and completely below in combination with the drawings in the utility model embodiment. Obviously, the described embodiment is a part of the embodiment of the utility model, rather than all the embodiments. Based on the embodiment in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0045] The embodiment of the utility model will be described below in combination with Figures 1 to 6 .

[0046] According to the embodiment of the utility model, a photovoltaic tile roof is provided, which comprises: a plurality of photovoltaic tile assemblies 1.

[0047] Specifically, the upper end of the photovoltaic tile assembly 1 has a first frame 2, the lower end of the photovoltaic tile assembly 1 has a second frame 3, the first frame 2 is fixedly connected with the roof 5, and the bottom of the second frame 3 is provided with a sealing structure 4. Among them, any two photovoltaic tile assemblies 1 adjacent along the slope direction of the roof 5 are parallel to each other, and the second frame 3 of the relatively upper photovoltaic tile assembly 1 is bonded with the top surface of the relatively lower photovoltaic tile assembly 1 through the sealing structure 4.

[0048] In the embodiment, as Figure 1 and Figure 2As shown, the roof 5 is a slope, and several photovoltaic tile modules 1 are arranged adjacently along the slope direction of the roof 5. Each photovoltaic tile module 1 is parallel to the roof 5. A first frame 2 is located at the upper end of the photovoltaic tile module 1, and a second frame 3 is located at the lower end of the photovoltaic tile module 1. For two adjacent photovoltaic tile modules 1, the second frame 3 of the upper photovoltaic tile module 1 is bonded to the top surface of the lower photovoltaic tile module 1 through a bottom sealing structure 4. This allows the lower end of the upper photovoltaic tile module 1 to be fixedly connected to the lower photovoltaic tile module 1 through the sealing structure 4 of the second frame 3, and the lower end of the upper photovoltaic tile module 1 overlaps the upper end of the lower photovoltaic tile module 1. The upper photovoltaic tile module 1 provides a compressive force to the lower photovoltaic tile module 1, and the sealing structure 4 seals the gap between the second frame 3 and the top surface of the photovoltaic tile module 1. The first frame 2 is fixedly connected to the roof 5, thus fixing the photovoltaic tile module 1 to the roof 5.

[0049] It should be noted that by fixing the lower end of the relatively upper photovoltaic tile component 1 to the relatively lower photovoltaic tile component 1 through the sealing structure 4 of the second frame 3, the lower end of the relatively upper photovoltaic tile component 1 and the upper end of the relatively lower photovoltaic tile component 1 are stacked.
