[0041] Referring to Figures 1-2B As shown, an embodiment of the present application provides a photovoltaic roof system, which comprises a tile base plate 100, a photovoltaic support and a photovoltaic module 420. The tile base plate 100 is connected to the roof. The photovoltaic support is connected to the tile base plate 100. The photovoltaic module 420 is connected to the photovoltaic support.

[0042] That is, the photovoltaic support and the photovoltaic module 420 are not directly connected to the roof, so that during installation, the roof is not damaged, thereby reducing the risk of roof leakage, and the photovoltaic roof system is not picky about the roof, and can be installed as long as the house structure meets the requirements. The tile base plate 100 can be arranged according to the roof design, has strong applicability, and has good aesthetics after construction. The photovoltaic support and the tile base plate 100 can be quickly connected, thereby improving the assembly efficiency.

[0043] Referring to Figure 2B As shown, in some embodiments, a plurality of tile base plates 100 are provided, and the plurality of tile base plates 100 are arranged along a first direction and overlap with each other. The two tile base plates 100 are connected by overlapping, that is, the two tile base plates 100 have an overlapping area, which can increase the connection area between the two adjacent tile base plates 100, thereby improving the connection effect and stability of the two adjacent tile base plates 100, and further improving the overall use reliability of the photovoltaic roof system. Figure 2B and Figure 3As shown, in some embodiments, the overlapping positions of the two can be fixed by fasteners such as screws, and the other end of the tile base plate 100 can be connected with the roof, for example, a batten 1000 is arranged on the roof, one end of the tile base plate 100 overlaps with the adjacent tile base plate 100, and the other end of the tile base plate 100 is connected to the batten 1000.

[0044] Referring to Figures 3-5 As shown, in some embodiments, a plurality of tile base plates 100 are arranged along a first direction, and the photovoltaic roof system further comprises a connecting structure 200 for connecting two adjacent tile base plates 100, the connecting structure 200 comprising a main body part 210 and two first connecting parts 220, the main body part 210 being located between the two adjacent tile base plates 100; the two first connecting parts 220 are arranged on the main body part 210 and are spaced apart along the first direction, and each first connecting part 220 is used for positioning a corresponding tile base plate 100. For example, Figure 3 As shown, the first direction is indicated by an arrow X. When the two adjacent tile base plates 100 are partially overlapped, that is, the two adjacent tile base plates 100 are in different planes, the first direction is the overlapping direction of the two adjacent tile base plates 100, that is, the direction perpendicular to the surface of the tile base plate 100 away from the other adjacent tile base plate 100. When the two adjacent tile base plates 100 are spaced apart and not overlapped, that is, the two adjacent tile base plates 100 can be in the same plane, the first direction is the arrangement direction of the two adjacent tile base plates, that is, the direction parallel to the surface of the tile base plate 100 away from the other adjacent tile base plate 100.

[0045] The above connecting structure 200 is arranged between the two adjacent overlapped tile base plates 100, and each first connecting part 220 is used for positioning and connecting a corresponding tile base plate 100. In this way, the connecting area between the connecting structure 200 and the tile base plate 100 is increased, and the connecting area between the two adjacent tile base plates 100 is increased, thereby improving the connecting effect and stability between the two adjacent tile base plates 100, and further improving the overall use reliability of the photovoltaic roof system.

[0046] Referring to Figures 3-5 As shown, in one of the embodiments, along the first direction, the two first connecting parts 220 and the main body part 210 respectively surround two first accommodating grooves 222, and parts of the two adjacent tile base plates 100 are respectively located in the first accommodating grooves 222. During assembly, the tile base plate 100 can be directly inserted into the first accommodating groove 222, so that the connecting structure 200 and the tile base plate 100 can be quickly connected, the assembly time is shortened, the production efficiency is improved, and rapid installation and disassembly are realized; and the connection between the connecting structure 200 and the tile base plate 100 is more concealed and smooth, and the overall appearance of the product is improved.

[0047] Referring to Figures 3-5As shown, in one embodiment, the first connecting portion 220 includes two first connecting segments 221 intersecting with each other, and the two first connecting segments 221 together with the main body portion 210 enclose a first accommodating groove 222; the two first connecting segments 221 are connected with two adjacent surfaces of the tile substrate 100 respectively. That is, the first connecting portion 220 is L-shaped, and the L-shaped first connecting portion 220 cooperates with the main body portion 210 to form a U-shaped structure, and the first accommodating groove 222 formed thereby is a U-shaped groove, so that the connecting structure 200 can be connected with three adjacent side surfaces of the tile substrate 100, the connecting area between the connecting structure 200 and the tile substrate 100 is improved, and the connecting effect of the two is further improved.

[0048] Referring to Figure 10 As shown, in other embodiments, the first connecting portion 220 can also be a straight line type, that is, the first connecting portion 220 includes one first connecting segment 221, and the first connecting segment 221 is connected with the main body portion 210 perpendicularly, and the two form an L-shaped structure. Further, in some embodiments, the upper end of the first connecting portion is flush with the upper surface of the tile substrate, so that after the tile substrates are laid, the surface flatness of the whole photovoltaic roof system is higher, and the aesthetic effect of the photovoltaic roof system is improved.

[0049] Referring to Figures 6-8 As shown, in one embodiment, the surface of one of the two adjacent tile substrates 100 facing the other tile substrate 100 is provided with a first clamping portion 101, and one of the first connecting portions 220 of the connecting structure 200 is clamped and cooperated with the first clamping portion 101. Through the clamping and cooperation of the first clamping portion 101 and the first connecting portion 220, the invasion of external substances such as dust and water is effectively prevented, and the protection level of the photovoltaic roof system is improved. For example, in Figure 7 As shown in the embodiment, the first connecting portion 220 of one of the tile substrates 100 is a straight line type, and the first connecting portion 220 is configured as a clamping block, and the first clamping portion 101 is configured as a clamping groove, and the clamping groove is opened on the lower surface of the tile substrate 100, and the clamping block of the connecting structure 200 is clamped and cooperated with the clamping groove of the tile substrate 100.

[0050] As Figure 10 As shown, in other embodiments, the first connecting portion 220 of one of the tile substrates 100 is a straight line type, and the first connecting portion 220 encloses a first accommodating groove 222 with the main body portion 210, that is, the side surface of the tile substrate 100 abuts against the first connecting portion 220, and the first connecting portion 220 is provided with a clamping block facing the side surface of the tile substrate 100, and the first clamping portion 101 is configured as a clamping groove, and the clamping groove is located on the side surface of the tile substrate 100, and the clamping block is clamped and cooperated with the clamping groove. In other embodiments, the first clamping portion 101 can also be a clamping block, and the first connecting portion 220 is provided with a clamping groove clamped with the clamping block.

[0051] As shown in Figure 4 or Figure 7 In one embodiment, as shown in the drawings, any two adjacent tile substrates 100 are partially laminated, and the main body 210 is located in the laminated area of the two adjacent tile substrates 100. As shown in Figure 4 The two adjacent tile substrates 100 are laminated along the first direction, with the left end of one tile substrate 100 laminated on the right end of the other tile substrate 100, i.e. there is an overlapping area between the two adjacent tile substrates 100. By laminating the plurality of tile substrates 100, the two adjacent tile substrates 100 form a larger contact surface in the laminated area, enhancing the shear resistance and pullout resistance of the tile substrate 100, improving the load bearing capacity and stability of the structure, thereby further improving the load bearing capacity of the photovoltaic roofing system. At the same time, the plurality of tile substrates 100 are laminated with each other, and the connecting structure 200 is arranged at the laminated position, which can avoid forming a gap between the adjacent tile substrates 100, effectively preventing external substances such as water and dust from entering, reducing the risk of water leakage, and improving the protection performance of the photovoltaic roofing system.

[0052] In other embodiments, the two adjacent tile substrates can also be spaced apart and not laminated, for example, the plurality of tile substrates are in the same plane, and the main body is arranged between the two adjacent tile substrates, and the two first connecting portions are respectively located on both sides of the main body along the first direction and connected with the corresponding tile substrates.

[0053] As shown in Figure 4 or Figure 7 In one embodiment, as shown in the drawings, any two adjacent tile substrates 100 are partially laminated, and the main body 210 is located in the laminated area of the two adjacent tile substrates 100. The connecting structure 200 further comprises a first support portion 230, which extends from one end of the main body 210 in a direction away from the other end of the main body 210, and the first support portion 230 supports the tile substrate 100, i.e. the first support portion 230 and the main body 210 form a linear shape. By arranging the first support portion 230 on the main body 210 to support the tile substrate 100, the contact area between the connecting structure 200 and the tile substrate 100 is further improved, and the connection effect between the two and the load bearing capacity of the tile substrate 100 are improved. At the same time, when the connecting structure 200 is under stress, it can evenly distribute the concentrated stress to a larger area through the first support portion 230, reducing the risk of local deformation or fracture of the connecting structure 200, and improving its use reliability.

[0054] As shown in Figures 3-5As shown, in an embodiment, the connecting structure 200 is connected between two adjacent tile substrates 100, which can increase the connecting area between the two adjacent tile substrates 100, thereby improving the connecting effect and stability between the two adjacent tile substrates 100, and further improving the overall use reliability of the photovoltaic tile.

[0055] In some embodiments, the tile substrate 100 is a composite tile, i.e., the tile substrate 100 is made of a composite material, such as a composite fiber. The composite tile has higher structural strength, and a plurality of composite tiles can form an integrated roof support system after being laid, which has good load-bearing capacity and meets the installation requirements of the photovoltaic module 420.

[0056] In some embodiments, the side surface of the tile substrate 100 away from the roof is provided with a drainage groove. For example, in the view shown, the side surface of the tile substrate 100 away from the roof is the front surface of the tile substrate 100, which is also the upper surface of the tile substrate 100. Figure 4 In the view shown, the side surface of the tile substrate 100 away from the roof is the front surface of the tile substrate 100, which is also the upper surface of the tile substrate 100.

[0057] In some embodiments, the side surface of the tile substrate 100 facing the roof is provided with a reinforcing portion. For example, in the view shown, the side surface of the tile substrate 100 facing the roof is the back surface of the tile substrate 100, which is also the lower surface of the tile substrate 100. Figure 4 In the view shown, the side surface of the tile substrate 100 facing the roof is the back surface of the tile substrate 100, which is also the lower surface of the tile substrate 100. By providing the reinforcing portion on the tile substrate 100, the structural strength of the tile substrate 100 can be enhanced, thereby improving the load-bearing capacity of the tile surface. In some embodiments, the reinforcing portion includes a plurality of reinforcing ribs. In some embodiments, the reinforcing ribs can be arranged in a crisscross manner.

[0058] Referring to Figures 6-8 As shown, in one embodiment, the photovoltaic roof system further includes a first fastener 310, which is arranged through the first connecting portion 220 and the tile substrate 100. As shown, Figure 4 As shown, when part of the tile substrate 100 is accommodated in the connecting structure 200, the first fastener 310 passes through the first connecting portion 220 and the tile substrate 100 in sequence from top to bottom. As shown, Figure 4 As shown, in some embodiments, one end of the first fastener 310 passes through the connecting structure 200 and is arranged in one of the tile substrates 100, i.e., the first fastener 310 does not pass out of the tile substrate 100. In other embodiments, the first fastener can also be arranged through the two adjacent tile substrates 100, i.e., the first fastener passes through the first connecting portion, one of the tile substrates, the main body portion, and the other tile substrate in sequence.

[0059] As shown, Figure 7As shown, in one embodiment, when the tile substrate 100 is snapped into place with the connecting structure 200, the first fastener 310 passes through a portion of the tile substrate 100, the first connecting portion 220, and a portion of the tile substrate 100 from left to right. In some embodiments, the first fastener 310 may be a self-tapping screw.

[0060] See Figure 2A , Figures 6-8 As shown, in one embodiment, the photovoltaic support includes purlins 410 and a first locking member 330. The purlins 410 are used to connect the photovoltaic modules 420; the first locking member 330 is fixed to the roof tile substrate 100 and connected to the purlins 410. This method enables the assembly of the roof tile substrate 100 and the photovoltaic modules 420. By directly connecting the photovoltaic modules 420 to the purlins 410 and then connecting the purlins 410 to the roof tile substrate 100, the photovoltaic support consists only of the purlins 410, thus reducing construction steps and improving assembly efficiency. Furthermore, since the photovoltaic modules 420 are connected to the purlins 410 instead of directly to the roof, this not only avoids damaging the roof but also reduces the risk of roof leaks, making it highly adaptable and aesthetically pleasing after installation.

[0061] See Figure 2A As shown, in some embodiments, the roof tile substrate 100 and the first locking member 330 are separate designs, with the first locking member 330 using a connecting bolt. In some embodiments, the roof tile substrate 100 is provided with a first connecting hole, which has an internal thread, and the first locking member 330 is detachably connected to the first connecting hole. In some embodiments, the first connecting hole is a blind hole structure, that is, the first locking member 330 does not penetrate the roof tile substrate 100, thereby reducing the risk of water leakage in the photovoltaic roof system and improving waterproof performance.

[0062] See Figure 9 As shown, in another embodiment, the first locking member 330 and the tile substrate 100 are an integral structure, which has high structural strength and can reduce production costs. That is, the first locking member 330 is part of the tile substrate 100. In some embodiments, the first locking member 330 and the tile substrate 100 can be integrally formed using a molding die. In some embodiments, during the forming of the tile substrate 100, one end of the first locking member 330 is embedded inside the tile substrate 100, achieving an integral arrangement of the two. This facilitates the connection between the tile substrate 100 and the purlin 410 and simplifies the connection steps. In some embodiments, the first locking member 330 can be a bolt.

[0063] See Figure 2AAs shown in the drawings, in some embodiments, the first locking member 330 is sleeved with a first locking cap 340 at one end of the purlin 410, and the first locking member 330 is locked and fixed at one end by the first locking cap 340, thereby improving the reliability of the connection between the tile base plate 100 and the purlin 410. In some embodiments, the first locking member 330 can be a bolt, and the first locking cap 340 can be a nut.

[0064] As shown in the drawings, Figure 2A and Figure 9 As shown in the drawings, in some embodiments, the photovoltaic support further comprises a crimping member 430 and a second locking member 440, the crimping member 430 is crimped on the side of the photovoltaic module 420 away from the purlin 410, and the second locking member 440 is sequentially arranged in the purlin 410, the photovoltaic module 420 and the crimping member 430, thereby fixing and connecting the photovoltaic module 420 on the purlin 410 through the crimping member 430 and the second locking member 440. In some embodiments, the second locking member 440 can be a T-shaped bolt. Specifically, during installation, the T-shaped bolt is placed in the purlin 410 upside down, and the part of the T-shaped bolt protruding out of the purlin 410 is bolted with the photovoltaic module 420 and the crimping member 430, thereby limiting the two sides of the photovoltaic module 420 through the crimping member 430 and the purlin 410, and improving the installation reliability of the photovoltaic module 420. In some embodiments, the second locking member 440 is sleeved with a second locking cap 450 at one end of the pressing block, and the second locking member 440 is locked and fixed by the second locking cap 450, thereby improving the connection reliability of the pressing block and the photovoltaic module 420.

[0065] As shown in the drawings, Figure 1 , Figures 3-4 As shown in the drawings, in some embodiments, the roof is provided with a batten 1000, and at least one of the connection structure 200 and the tile base plate 100 is connected with the batten 1000.

[0066] As shown in the drawings, Figure 1 As shown in the drawings, in some embodiments, the roof is a sloping roof, and the tile base plate 100 is installed on the sloping roof.

[0067] As shown in the drawings, Figures 1-3 As shown in the drawings, in some embodiments, the tile base plate 100 has a certain angle with the sloping roof, and the tile base plate 100 is not parallel to the sloping roof. That is, for any tile base plate 100, the distance between the left end of the tile base plate 100 and the sloping roof is different from the distance between the right end of the tile base plate 100 and the sloping roof, for example, the distance between the left end of the tile base plate 100 and the sloping roof is greater than the distance between the right end of the tile base plate 100 and the sloping roof. Through such an inclined arrangement, the photovoltaic module 420 installed on each tile base plate 100 can be in the same plane.

[0068] As shown in the drawings, Figures 6-8As shown, in one embodiment, the photovoltaic roofing system further comprises a second fastener 320, which is arranged through the connecting structure 200 and the batten 1000, so as to connect the tile base plate 100 to the batten 1000. In some embodiments, one of the first connecting portions 220 of the connecting structure 200 is configured with a first countersunk hole 223, one end of the second fastener 320 is arranged in the countersunk hole, and the other end of the second fastener 320 is connected to the batten 1000. Through the design of the first countersunk hole 223, after the tile base plate 100 is connected to the batten 1000, the overall flatness is higher, and the aesthetic degree is better. In some embodiments, one end of the second fastener 320 is arranged through the connecting structure 200, and the other end is arranged through the batten 1000, and the second fastener 320 can not be arranged out of the batten 1000, so as to reduce the risk of water leakage. In some embodiments, the second fastener 320 can be a self-tapping screw.

[0069] In other embodiments, the second fastener can be arranged through the tile base plate, the first connecting portion of the connecting structure, and the batten in sequence. In other embodiments, the tile base plate can be directly connected to the batten, and the installation of the tile base plate can be achieved by arranging a fastener such as a self-tapping screw through the tile base plate and the batten. The second fastener can be arranged out of or not arranged out of the batten, which can be designed according to actual needs.
