DETAILED DESCRIPTION OF THE INVENTION

[0021] In order to make the above objects, features and advantages of the present application more clearly comprehensible, specific embodiments of the present application will be described in detail below in conjunction with the accompanying drawings.

[0022] In the following description, numerous specific details are set forth to facilitate a thorough understanding of the present specification; however, the present application may be embodied in other forms other than those described, and therefore the present application is not limited to the specific examples disclosed below.

[0023] As set forth in this application and the claims, unless the context clearly indicates otherwise, terms such as "a," "one," "one," "a kind," and / or "the" do not specifically refer to the singular but may also include the plural. Generally, the terms "comprising" and "including" only indicate the inclusion of explicitly identified steps and elements, and do not constitute an exclusive list of these steps and elements; a method or apparatus may include other steps or elements.

[0024] It should also be noted that the use of terms such as "first" and "second" to define components is merely to facilitate distinguishing between corresponding components, and that unless otherwise stated, the terms do not have any special meaning and therefore should not be understood as limiting the scope of protection of the present application. Furthermore, although the terms used in the present application are selected from well-known terms, some terms described in the specification of the present application have been selected by the applicant at his / her own discretion, and their detailed meanings will be explained in the relevant parts of the description of this specification. It is also required to understand the present application not only by the actual terms used but also by the meanings contained in each term.

[0025] Next, the photovoltaic roofing tile of the present application will be described using specific examples.

[0026] 1 to 3 are a schematic perspective view, a schematic front view, and a schematic plan view, respectively, of a profile of an embodiment of the present application. As shown with reference to FIGS. 1 to 3, a photovoltaic tile 100 includes a tile base 110 and a photovoltaic module 120. Next, the tile base 110 and the photovoltaic module 120 will be described.

[0027] 4 to 6 are a schematic perspective view, a schematic main view, and a schematic plan view, respectively, of a roof tile base according to an embodiment of the present application. As shown in Fig. 4 to Fig. 6, the roof tile base 110 includes a substrate 111, a lift-up portion 112, a bonding region 113, and a first connecting portion.

[0028] Specifically, as shown in FIGS. 4 and 5, the roof tile base has opposing first and second sides 111c and 111d, and the substrate 111 has opposing first and second surfaces 111a and 111b. The first surface 111a faces the roof when the substrate 111 is laid on the roof. The lift-up portion 112 is located on the second surface 111b and extends in a first direction D1 from the first side 111c toward the second side 111d. Methods for connecting the lift-up portion 112 to the second surface 111b include screw connection and adhesive bonding, and it is also possible to simultaneously manufacture the substrate 111 and the lift-up portion 112 thereon by an integral molding process.

[0029] It is understood that the number of lift-up portions 112 in the present application is not limited to two as shown in Fig. 4. It may be one, three, or four.

[0030] As shown in FIG. 4, the height of the lift-up portion 112 relative to the second surface 111b gradually increases from the first end 112a to the second end 112b along the first direction D1. As shown in FIG. 5, the second end 112b is adjacent to the second side edge 111d. As shown in FIGS. 5 and 6, in one embodiment, the lift-up portion 112 has a lift-up surface 112c and a fixing surface. Because the fixing surface is connected to the second surface 111b of the substrate 111, the fixing surface is not visible in the figure. A predetermined angle θ is formed between the lift-up surface 112c and the fixing surface. The height of the second end 112b relative to the second surface 111b can be adjusted by changing the magnitude of the predetermined angle θ. As shown in FIGS. 4 and 5, in this application, the height h1 of the second end 112b of the lift-up portion 112 relative to the second surface 111b is the same as the thickness t1 of the tile base 110 along the first side edge 111c. In this way, when multiple photovoltaic tiles are joined adjacently in the first direction, the photovoltaic panels can be kept flush with each other. Also, by lifting up one end of the photovoltaic module with the lift-up part, a space is formed between the photovoltaic module and the tile base, which is advantageous for heat dissipation of the photovoltaic module.

[0031] It should be noted that the lift-up portion in the present application is not limited to the case shown in Fig. 4. For example, based on the configuration shown in Fig. 4, the dimension of the lift-up portion 112 along the first direction D1 can be reduced, or the dimension of the lift-up portion 112 along the second direction D2 can be increased. Here, the second direction D2 refers to the extension direction of the bonding region 113 as shown in Fig. 4.

[0032] As shown in FIGS. 4 and 5, the substrate 111 further has a joining region 113 and an attachment portion 115. The joining region 113 is close to the second side edge 111d of the tile base 110 and is adjacent to the second end 112b of the lift-up portion 112. The attachment portion 115 is located on the first surface 111a of the substrate 111 and on the second side edge 111d. When laying photovoltaic tiles on a roof, the tile base 110 can be joined to another tile base located at the upper end in the first direction D1 by the joining region 113, and can be joined to a beam for attaching the photovoltaic tiles by the attachment portion 115. Methods for connecting and laying tile bases will be described later and will not be described here.

[0033] The first connection portion of the roof tile base in the present application is used to detachably connect the roof tile base to the photovoltaic module. As shown in Figures 4 and 6, the first connection portion is a mounting hole 114a located at the upper end of the substrate 111 in the first direction D1. The first connection portion in the present application is not limited to the above-described embodiment and may, for example, be another connection structure that allows for quick detachment or may be located at another position on the substrate. The method of connecting the roof tile base to the photovoltaic module will be described later and will not be described here.

[0034] 4 and 6, in some embodiments, the roof tile base further includes a first drainage groove 116. The first drainage groove 116 is adjacent to one of two opposing side edges of the roof tile base along the second direction D2, and extends in the first direction D1. The first drainage groove 116 has an opening 116a at one end near the first end 112a of the lift-up portion 112. The first drainage groove 116 can be used to collect rainwater that drips on the surface of the photovoltaic panel and then drain it to the outside of the roof tile base through the opening 116a.

[0035] Continuing to refer to FIGS. 4 to 6, the roof tile base 110 further includes a second drainage groove 118 located on the second surface 111b. The second drainage groove 118 extends in the second direction D2 and has an opening 118a facing outward from the roof tile base along the second direction D2. The bottom surface of the second drainage groove 118 has a certain slope, as shown in FIG. 4. Specifically, the second drainage groove 118 has an end 118b opposite the opening 118a along the second direction D2, and the opening 118a is closer to the first surface 111a than the end 118b. This allows the second drainage groove 118 to promote the removal of water from the second surface 111b. The form of the second drainage groove in the present application is not limited to the above-described embodiment. For example, while FIG. 4 shows two second drainage grooves arranged opposite each other along the second direction D2, it should be noted that in other embodiments, there may be only one second drainage groove. For example, in some embodiments, if there is one second drain groove, this corresponds to extending one second drain groove 118 in Figure 4 in the second direction D2 so that the other end 118b opposite the opening 118a approaches the first drain groove 116.

[0036] In addition to the second drainage grooves described above being able to promote drainage on the second surface, the provision of an inclined surface on the second surface can also promote drainage on the second surface.

[0037] 7 is a schematic perspective view of a roof tile substrate according to an embodiment of the present application. As shown in FIG. 7, the second surface 111b has a first inclined surface 111b-1 and a second inclined surface 111b-2. The first inclined surface 111b-1 and the second inclined surface 111b-2 are adjacent to two opposite sides of the substrate 111 along the second direction D2. One side of the first inclined surface 111b-1 that is close to the lift-up portion 112 is lifted up along the second direction D2, and one side of the second inclined surface 111b-2 that is close to the lift-up portion 112 is lifted up along the second direction D2. As a result, the first inclined surface 111b-1 and the second inclined surface 111b-2 promote the removal of water from the second surface 111b.

[0038] 4 and 5, in some embodiments, the first side 111c of the tile base 110 has several cable avoidance slots 119. The cable avoidance slots 119 are used to accommodate cables to avoid interference of the cables with the joints between the tile bases 110, and can improve the stability of the joints between the tile bases 110. Figures 8 to 10 are a schematic perspective view, a schematic front view, and a schematic plan view of a photovoltaic module according to one embodiment of the present application.

[0039] As shown in Figures 8 to 10, the photovoltaic module 120 includes a photovoltaic panel 121 and a second connecting portion. As shown in Figure 2, the photovoltaic panel 121 is provided on the lift-up portion 112 and is detachably connected to the roof tile base 110 by fitting the first connecting portion and the second connecting portion. The first connecting portion and the second connecting portion in this application can realize quick detachment between the roof tile base and the photovoltaic module, and this application includes all connection structures that can realize quick detachment between the roof tile base and the photovoltaic module, and does not limit the specific structures of the first connecting portion and the second connecting portion. Two non-limiting examples are provided to facilitate understanding of the connecting components in this application.

[0040] Example 1 4 and 8, in this embodiment, the first connecting portion has an attachment hole 114a provided in the joining region 113 and an engagement groove 114b facing the attachment hole 114a. In this embodiment, the attachment hole 114a is implemented as a bolt hole. As shown in FIG. 4, the attachment hole 114a is located in the center of the joining region 113 in the second direction D2 and close to the second end 112b of the lift-up portion 112. The engagement groove 114b is a groove located at one end of the substrate 111 close to the first side edge 111c.

[0041] 8, the second connecting portion includes an engaging member 122a and a connecting member 122b that face each other. The connecting member 122b is located at the raised end of the photovoltaic panel 121, and is detachably connected to the photovoltaic panel 121. The connecting member 122b has a through hole that corresponds to the mounting hole 114a.

[0042] The method for attaching the photovoltaic module 120 to the roof tile base 110 is as follows. First, as shown in FIGS. 1, 4, and 8, the two engaging members 122a of the photovoltaic panel 121 are engaged with the corresponding engaging slots 114b in the substrate 111, respectively. Then, the through holes of the connecting members 122b are aligned with the mounting holes 114a. Then, bolts 130 are passed through the through holes of the connecting members 122b and the mounting holes 114a to connect the connecting members 122b to the mounting holes 114a. It should be noted that the above-described embodiment is merely illustrative. For example, the mounting holes 114a can be guide holes without threads, and after aligning the guide holes, tapping screws can be passed through the through holes of the connecting members 122b to connect the photovoltaic module to the roof tile base.

[0043] Example 2 FIG. 11 is a schematic perspective view of a roof tile base according to an embodiment of the present application, and FIG. 12 is a schematic perspective view of a photovoltaic module according to an embodiment of the present application. As shown in FIG. 12, in Example 2, the first connection portion is implemented as four mounting holes 114c located on the second surface 111b of the roof tile base 110. As shown in FIG. 13, the second connection portion is implemented as four snaps 122c located on the surface of the photovoltaic panel 121 facing away from the sun. When connecting the photovoltaic module to the roof tile base, the four snaps 122c can be engaged with the corresponding mounting holes 114c, allowing the photovoltaic module to be quickly attached to and detached from the roof tile base. It should be noted that FIGS. 11 and 12 only illustrate the structure of a portion of the roof tile base and the photovoltaic module. For other details, please refer to the relevant descriptions above and will not be further discussed here.

[0044] When packaging and transporting photovoltaic roofing tiles to an installation site, the photovoltaic modules and the roofing tile substrate themselves have different structures and strengths. Therefore, if the photovoltaic modules and the roofing tile substrate are assembled and then packaged, special packaging materials must be designed. Furthermore, assembled photovoltaic roofing tiles have high logistics requirements. This increases the packaging and transportation costs of the photovoltaic roofing tiles. In the above embodiment, the first and second connecting members enable quick detachment between the roofing tile substrate and the photovoltaic assembly. This allows the roofing tile substrate and the photovoltaic modules to be packaged and transported separately, thereby reducing packaging and transportation costs. When a photovoltaic module needs to be replaced, the photovoltaic module can be quickly removed and installed. In addition, the present application connects the photovoltaic panel and the tile base using a second connecting part located on the surface of the photovoltaic panel facing away from the sun.Compared to the case where a connecting member is provided on the side edge of the photovoltaic panel, the photovoltaic panel of the present application does not have a side edge that is higher than the surface of the photovoltaic panel facing the sun, which is advantageous in allowing dust that has accumulated on the surface of the photovoltaic panel facing the sun to be washed away by rainwater.

[0045] As shown in FIG. 1 , in some embodiments, the first side edge 111 c of the roof tile base 110 has a connecting member avoidance groove 117. The bottom surface of the connecting member avoidance groove 117 faces the direction in which the roof will be positioned when the photovoltaic roof tile 100 is installed. FIG. 13 is a schematic perspective view of a photovoltaic roof according to one embodiment of the present application, and FIG. 14 is a schematic perspective view of the photovoltaic roof in FIG. 13. As shown in FIGS. 13 and 14 , when two adjacent photovoltaic roof tiles 100 and 200 are joined, the connecting member avoidance groove 117 of the photovoltaic roof tile 200 is used to accommodate the connecting member of the photovoltaic roof tile 100. This is advantageous in improving the stability of the joint between adjacent photovoltaic roof tiles.

[0046] 8, in one embodiment, the photovoltaic module 120 further includes a junction box 123. The junction box 123 is located on the surface of the photovoltaic module 120 facing away from the sun. The photovoltaic module 120 can be connected to external components via the junction box 123.

[0047] To facilitate understanding of the connection method between photovoltaic tiles in this application, an example for attaching photovoltaic tiles to a roof is shown here.

[0048] As shown in FIG. 14 , the roof has three beams 140 spaced apart in a first direction D1. Photovoltaic tile 100, photovoltaic tile 200, and photovoltaic tile 300 are sequentially joined to the beams 140 along the first direction D1. Specifically, the lower end of photovoltaic tile 200 is joined to the joining region 113 of photovoltaic tile 100, and the lower end of photovoltaic tile 300 is joined to the joining region 113 of photovoltaic tile 200. Photovoltaic tile 100, photovoltaic tile 200, and photovoltaic tile 300 are each joined to the corresponding beam 140 by their respective mounting portions 115. Here, the mounting portions 115 are protrusions located on the first surface 111 a of the substrate 111 and extending in the second direction, as shown in FIG. 5 . The photovoltaic tile can be joined to the beam 140 by the mounting portion 115 due to its own weight, and downward movement of the photovoltaic tile along the first direction D1 can be prevented. Note that the structure and position of the mounting portion are not limited to the above-described embodiment, and may be set according to the specific structure of the roof on which the photovoltaic tile is to be mounted.

[0049] 4 and 5, the height h1 of the second end 112b of the lift-up portion 112 relative to the second surface 111b is the same as the thickness t1 of one end of the tile base near the first side edge 111c. As shown in Figures 13 and 14, one end of the photovoltaic panel 121 located on the tile base 110 is lifted up by the second end 112b of the lift-up portion 112, so that the photovoltaic panels 121 on adjacent tile bases along the first direction D1 are positioned on the same plane.

[0050] As shown in FIG. 14 , in some embodiments, adjacent photovoltaic panels 121 of photovoltaic tile 100, photovoltaic tile 200, and photovoltaic tile 300 are joined together without gaps by contacting the sides of the photovoltaic panels 121 that face each other along the first direction D1. This has the advantage of preventing dust from entering the space below the photovoltaic panels through the gaps between the photovoltaic panels, effectively preventing dust accumulation. Furthermore, the photovoltaic tile of the above embodiment uses a lift-up section to lift up one end of the photovoltaic module, making the photovoltaic panels of adjacent photovoltaic tiles flush with each other, improving the aesthetic appearance of the photovoltaic tile and preventing dust accumulation.

[0051] In one embodiment of the present application, the number of roof tile substrates covered by one photovoltaic module is two or more. It is understood that the number of roof tile substrates covered by a photovoltaic module can be determined according to demand. For example, see the schematic perspective views of photovoltaic roofs in two embodiments of the present application as shown in Figures 15 and 16. Unlike the embodiment of Figure 13, in which one photovoltaic module covers one roof tile substrate, in the embodiment of Figure 15, the photovoltaic module 400 is roughly square and covers four roof tile substrates. The present application does not limit the shape of the photovoltaic module. For example, in the embodiment of Figure 16, the photovoltaic module 500 is roughly rectangular and covers four roof tile substrates 110.

[0052] Another aspect of the present application provides a sloped photovoltaic roof, which includes several photovoltaic tiles as described above. One end of the photovoltaic modules on the photovoltaic tiles laid on the photovoltaic roof is raised, so that the photovoltaic panels of adjacent photovoltaic tiles are flush with each other, improving the aesthetic appearance of the photovoltaic tiles and preventing the accumulation of dust.

[0053] Although the basic concepts have been described above, it will be apparent to those skilled in the art that the above disclosure is merely illustrative and not limiting of the present application. Although not explicitly stated herein, those skilled in the art may make various modifications, improvements, and amendments to the present application. Such modifications, improvements, and amendments are proposed herein and therefore fall within the spirit and scope of the exemplary embodiments of the present application.

For example, "one embodiment," "one embodiment," and / or "some embodiments" refer to features, configurations, or characteristics associated with at least one embodiment of the present application. Therefore, it should be emphasized and noted that "one embodiment," "one embodiment," or "one alternative embodiment" mentioned more than once in different places in this specification do not necessarily refer to the same embodiment. Furthermore, some features, configurations, or characteristics in one or more embodiments of the present application may be combined as appropriate.
