[0027] Conventional photovoltaic tile frame 1 and roof tile 2 are connected by connector 3. However, the connection between photovoltaic frame 1 and connector 3 is usually fixed by bolts, which makes the installation of photovoltaic tile and roof tile 2 more complicated.

[0028] To solve the above problems, refer to Figures 1-5 , Figure 1 This illustration shows a structural diagram of a photovoltaic roof according to an embodiment of this application. Figure 2 Show Figure 1 The diagram shows a partially enlarged structural schematic of region A of the photovoltaic roof. Figure 3 This illustration shows a schematic diagram of a frame structure provided in an embodiment of this application. Figure 4 The diagram shows a structural schematic of a connector provided in an embodiment of this application. Figure 5 This diagram illustrates a structural schematic of a tile assembly provided in an embodiment of this application.

[0029] This application provides a photovoltaic frame module, including a frame 1. The frame 1 is connected to the tile 2 via a connector 3. The frame 1 includes a main body 11, a first connecting part 12, and a second connecting part 13. The main body 11 is used to connect to a laminate 4. The first connecting part 12 is connected to one end of the main body 11 and is used to detachably connect to a tile strip 5. The second connecting part 13 is connected to the other end of the main body 11. The second connecting part 13 is bent toward the first connecting part 12 to form a first bent part 131. The connector 3 is bent to form a second bent part 31. The first bent part 131 and the second bent part 31 are hooked together.

[0030] It should be understood that the photovoltaic frame assembly includes a frame 1, which includes a main body 11, a first connecting part 12, and a second connecting part 13. The main body 11, the first connecting part 12, and the second connecting part 13 can be welded or integrally formed. In one example, the main body 11, the first connecting part 12, and the second connecting part 13 are made of the same material, therefore, the main body 11, the first connecting part 12, and the second connecting part 13 are integrally formed. The photovoltaic tile includes a laminate 4, and the main body 11 is used to connect to the edge of the laminate 4, thereby connecting the laminate 4 to the frame 1.

[0031] The first connecting part 12 is located at one end of the main body 11 along the height direction, that is, the first connecting part 12 is located at the lower end of the main body 11. The first connecting part 12 is inclined and the lower end of the first connecting part 12 is connected to the main body 11. The angle formed by the first connecting part 12 and the side wall of the main body 11 is an obtuse angle, so that the first connecting part 12 fits against the upper plane of the batten 5, thereby facilitating the detachable connection of the first connecting part 12 and the batten 5 using fasteners such as bolts and rivets.

[0032] The second connecting portion 13 is located at the other end of the main body portion 11 along the height direction, that is, the second connecting portion 13 is located at the upper end of the main body portion 11, and the second connecting portion 13 extends along the extending direction of the upper plane of the main body portion 11. The end of the first connecting portion 12 is bent toward the first connecting portion 12 to form a first bent portion 131, that is, the opening of the first bent portion 131 faces downward.

[0033] One end of the connector 3 is detachably connected to the tile 2 and can be connected by fasteners such as bolts or rivets. The end of the connector 3 away from the tile 2 is bent to form a second bent portion 31, and the opening of the second bent portion 31 is upward.

[0034] During installation, the main body 11 is first connected to the laminate 4, then the first connecting part 12 is connected to the tile strip 5, one end of the connector 3 is connected to the tile 2, and then the tile 2 is placed on the upper surface of the laminate 4. That is, when the tile 2 wants to move downward, the laminate 4 restricts the movement of the tile 2. Then, the second bending part 31 of the connector 3 is hooked to the first bending part 131 of the frame 1. When the tile 2 wants to move upward, the first bending part 131 and the second bending part 31 restrict the movement of the tile 2, thereby preventing the tile 2 from detaching from the photovoltaic tile and thus improving the wind resistance of the photovoltaic tile and the tile.

[0035] This application uses the first bending part 131 and the second bending part 31 to hook the tile 2 to the photovoltaic tile. Compared with the bolt fixing method, this application reduces the installation difficulty of the photovoltaic tile and the tile 2.

[0036] Reference Figure 2 and Figure 3 In some optional embodiments, the side of the main body 11 facing away from the roof strip 5 is the receiving surface 111, which is connected to the bottom surface of the laminate 4 via a first adhesive layer 6. The receiving surface 111 is parallel to the bottom surface of the laminate 4. During installation, the bottom surface at the edge of the laminate 4 is placed on the receiving surface 111, that is, the main body 11 can support the laminate 4 through the receiving surface 111. To improve the connection effect between the laminate 4 and the main body 11, the receiving surface 111 and the laminate 4 are fixed together by the first adhesive layer 6, which is made of structural adhesive.

[0037] In some optional embodiments, the main body 11 has a protruding abutment portion 14 on the side opposite to the roof strip 5, and the side of the laminate 4 is connected to the abutment portion 14 through a second adhesive layer 7. The abutment portion 14 is made of the same material as the main body 11 and is integrally formed with the main body 11. The abutment portion 14 is perpendicular to the receiving surface 111. When the laminate 4 is installed at the receiving surface 111, the side wall of the laminate 4 abuts against the abutment portion 14, further improving the stability of the connection between the main body 11 and the laminate 4. The abutment portion 14 and the receiving surface 111 can wrap around the edge of the laminate 4, protecting the edge of the laminate 4. In order not to affect the connection between the photovoltaic tile and the tile 2, the height of the abutment portion 14 is flush with the upper surface of the laminate 4.

[0038] Furthermore, in order to improve the tightness and sealing of the connection between the laminate 4 and the abutment 14, a second adhesive layer 7 is provided between the laminate 4 and the abutment 14. The second adhesive layer 7 is a waterproof sealant.

[0039] In some optional embodiments, a support portion 15 protrudes from the side of the main body 11 facing away from the connector 3. The height of the support portion 15 is lower than the height of the receiving surface 111. The support portion 15 is connected to the bottom surface of the laminate 4 via a flexible member 8. The material of the support portion 15 is the same as that of the main body 11. The support portion 15 and the main body 11 are integrally formed. The height of the support portion 15 is lower than the height of the receiving surface 111, and a flexible member 8 is provided between the support portion 15 and the laminate 4. The provision of the support portion 15 and the flexible member 8 can further support the laminate 4 and improve the support effect of the frame 1 on the laminate 4. The flexible member 8 is a flexible gasket, which can prevent damage to the laminate 4.

[0040] In some alternative embodiments, the main body 11 is provided with an inner cavity 16, which extends through the main body 11 along its length. The inner cavity 16 can reduce the material used in the main body 11, saving the cost of the main body 11, and can also reduce the weight of the frame 1 to achieve the requirement of lightweight frame 1.

[0041] In some optional embodiments, reinforcing ribs 112 protrude from the inner wall of the main body 11. The reinforcement ribs 112 enhance the strength of the main body 11 and reduce the probability of deformation. The reinforcing ribs 112 are integrally formed with the main body 11. The reinforcing ribs 112 extend along the length of the main body 11. The reinforcing ribs 112 can be located on the inner upper wall or the inner side wall of the main body 11, and this application does not impose any limitations. This application also does not limit the number of reinforcing ribs 112. The number of reinforcing ribs 112 can be one, two, or more. When multiple reinforcing ribs 112 are provided, they are spaced apart. In one example, four reinforcing ribs 112 are provided. Two reinforcing ribs 112 are located on the inner upper wall of the main body 11 and are spaced apart, and two reinforcing ribs 112 are located on the inner lower wall of the main body 11 and are spaced apart.

[0042] Reference Figures 1-3 This application also includes photovoltaic tiles, which include a laminate 4 and a photovoltaic frame assembly as described in any of the above claims. The laminate 4 is connected to the frame 1 of the photovoltaic frame assembly. The frame 1 includes a main body 11, a first connecting part 12, and a second connecting part 13. The main body 11 is used to connect to the laminate 4. The first connecting part 12 is connected to one end of the main body 11 and is used to detachably connect to the tile strip 5. The second connecting part 13 is connected to the other end of the main body 11 and is bent toward the first connecting part 12 to form a first bent part 131. One end of the connector 3 is connected to the tile 2, and the other end of the connector 3 is bent to form a second bent part 31. The first bent part 131 and the second bent part 31 are hooked together.

[0043] This application uses the first bending part 131 and the second bending part 31 to hook the tile 2 to the photovoltaic tile. Compared with the bolt fixing method, this application reduces the installation difficulty of the photovoltaic tile and the tile 2.

[0044] Reference Figure 1 , Figure 2 as well as Figure 4 This application also includes a connector 3, one end of which is detachably connected to the tile 2, and the other end of which is bent to form a second bend 31. The second bend 31 is used to hook with the first bend 131 of the frame 1 of the photovoltaic frame assembly described in any of the above claims. The second bend 31 of the connector 3 hooks with the first bend 131 of the frame 1, thereby hooking the tile 2 to the photovoltaic tile. Compared with the bolt fixing method, this application reduces the installation difficulty of the photovoltaic tile and the tile 2.

[0045] A guide portion 311 is formed at the end of the second bend 31. The guide portion 311 is inclined and its upper inclined end is connected to the second bend 31. The guide portion 311 and the second bend 31 are integrally formed. The lower end of the guide portion 311 is lower than the second bend 31. Since the installation gap between the connector 3 and the frame 1 is small, the guide portion 311 can guide the second bend 31 to extend into the first bend 131, improving the convenience of the second bend 31 extending into the first bend 131 and improving the feasibility of installation of this application.

[0046] Reference Figures 1-5 This application also includes a photovoltaic roof, which includes a tile 2, a batten 5, a photovoltaic tile as described in any of the above claims, and a connector 3 as described in any of the above claims. The first connecting portion 12 of the frame 1 of the photovoltaic tile is detachably connected to the batten 5. The second bent portion 31 of the connector 3 hooks with the first bent portion 131 of the frame 1 of the photovoltaic tile. The end of the connector 3 away from the second bent portion 31 is detachably connected to the tile 2. This application hooks the tile 2 to the photovoltaic tile through the hooking of the first bent portion 131 and the second bent portion 31. Compared to bolt fixing, this application reduces the installation difficulty of the photovoltaic tile and the tile 2.

[0047] In some alternative embodiments, the first connecting portion 12 is detachably connected to the batten strip 5 via a first fastener 9. The first fastener 9 can be a bolt, rivet, or other fastener; in one example, the first fastener 9 is a self-tapping screw.

[0048] In some alternative embodiments, the connector 3 and the tile 2 are detachably connected via a second fastener 10. The second fastener 10 can be a bolt, rivet, or other fastener; in one example, the second fastener 10 is a rivet.

[0049] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
