[0041] In the first aspect, as shown in FIG. 1 , an embodiment of the present application provides a photovoltaic tile fixing structure 11 , which is used to fix photovoltaic tiles 12 , and includes a fixing member 111 , an assembly member 112 and an anti-slip mechanism 113 .

[0042] The fixing member 111 is used to be installed on the attachment surface. The assembly member 112 is connected to one end of the fixing member 111. The assembly member 112 is provided with a receiving cavity 112a, and the receiving cavity 112a is used to embed the frame of the photovoltaic tile 12. The anti-slip mechanism 113 is provided on the fixing member 111 and / or the cavity wall of the receiving cavity 112a, and the anti-slip mechanism 113 is used to prevent the frame from slipping out.

[0043] In one example, the anti-slip mechanism 113 is disposed on the fixing member 111. In another example, the anti-slip mechanism 113 is disposed on the cavity wall of the accommodating cavity 112a. In yet another example, the anti-slip mechanism 113 is disposed on the fixing member 111 and on the cavity wall of the accommodating cavity 112a.

[0044] Here, it should be noted that the fixing member 111 can be installed on the flat tile 3 and / or the tile hanging strip 2, and can also be installed on other photovoltaic tiles 12.

[0045] The photovoltaic tile fixing structure 11 provided in the embodiment of the present application can be installed on an attachment surface by setting a fixing part 111, and the frame of the photovoltaic tile 12 can be embedded in the accommodating cavity 112a of the assembling part 112 by setting an assembly part 112, and the frame of the photovoltaic tile 12 can be prevented from escaping from the accommodating cavity 112a along the first direction X by setting an anti-slip mechanism 113. In this way, on the one hand, the structure of the photovoltaic tile fixing structure 11 is relatively simple. When assembling the photovoltaic tile 12, it is only necessary to embed the frame of the photovoltaic tile 12 into the accommodating cavity 112a, which is conducive to reducing the difficulty of installing the photovoltaic tile 12; on the other hand, the photovoltaic tile fixing structure 11 can be assembled independently, and the length of the photovoltaic tile fixing structure 11 can be made into a standard length, thereby realizing the standardization of the photovoltaic tile fixing structure 11. Further, when assembling the photovoltaic tile 12, the installation position of the photovoltaic tile fixing structure 11 can be adjusted according to the actual assembly position of the photovoltaic tile 12; on the other hand, the anti-slip mechanism 113 can improve the assembly stability of the photovoltaic tile 12, thereby improving the wind resistance of the photovoltaic tile 12; on the other hand, when the photovoltaic tile 12 needs to be replaced, the upper frame 122 of the photovoltaic tile 12 can be pulled out from the accommodating cavity 112a at a certain angle, thereby helping to realize the independent disassembly and assembly of the photovoltaic tile 12.

[0046] In one embodiment, as shown in FIG. 1 , the assembly part 112 includes a first assembly part 1121, a second assembly part 1122, and a third assembly part 1123. One end of the first assembly part 1121 is connected to the fixing member 111, and the other end of the first assembly part 1121 extends in a direction away from the fixing member 111. One end of the second assembly part 1122 is connected to the first assembly part 1121, and the other end of the second assembly part 1122 extends in a direction away from the first assembly part 1121. The extension direction of the second assembly part 1122 intersects with the extension direction of the first assembly part 1121. One end of the third assembly part 1123 is connected to the second assembly part 1122, and the other end of the third assembly part 1123 extends in a direction close to the fixing member 111. The extension direction of the third assembly part 1123 intersects with the extension direction of the second assembly part 1122. Among them, the first assembly part 1121, the second assembly part 1122, and the third assembly part 1123 are arranged to form a receiving cavity 112a.

[0047] In this way, the structure of the assembly part 112 can be made simpler, and the difficulty of manufacturing and assembling the assembly part 112 can be reduced.

[0048] In a specific embodiment, as shown in FIG. 1 , the fixing member 111 , the first assembly portion 1121 and the third assembly portion 1123 all extend along a first direction X, and the second assembly portion 1122 extends along a second direction Y, and the first direction X and the second direction Y are perpendicular.

[0049] In a specific embodiment, the second assembly portion 1122 is close to one end of the first assembly portion 1121 and connected to one end of the first assembly portion 1121 away from the fixing member 111. The third assembly portion 1123 is close to one end of the second assembly portion 1122 and connected to one end of the second assembly portion 1122 away from the first assembly portion 1121.

[0050] In one embodiment, a guide surface 11231 is provided at one end of the third assembly portion 1123 away from the second assembly portion 1122, and the guide surface 11231 is located on a side of the third assembly portion 1123 close to the accommodating cavity 112a. By providing the guide surface 11231, on the one hand, it is convenient to insert the upper frame 122 of the photovoltaic tile 12 into the accommodating cavity 112a or pull it out of the accommodating cavity 112a; on the other hand, it prevents the assembly part 112 from scratching the photovoltaic tile 12.

[0051] Exemplarily, the guide surface 11231 may be an inclined plane or a curved surface.

[0052] In one embodiment, as shown in FIG2 , the assembly part 112 is further provided with a first snap-fit ​​groove 112b, which is located on a side of the assembly part 112 away from the accommodating cavity 112a. By providing the first snap-fit ​​groove 112b on the assembly part 112, it is convenient to connect the photovoltaic tile fixing structure 11 with the overlap member 14 on the photovoltaic tile 12, thereby realizing the overlap connection of two adjacent photovoltaic tiles 12.

[0053] In one embodiment, as shown in FIG. 2 , the assembly part 112 further includes a fourth assembly part 1124 and a fifth assembly part 1125, one end of the fourth assembly part 1124 is connected to the third assembly part 1123, and the other end of the fourth assembly part 1124 extends in a direction away from the third assembly part 1123; the extension direction of the fourth assembly part 1124 intersects with the extension direction of the third assembly part 1123. One end of the fifth assembly part 1125 is connected to the fourth assembly part 1124, and the other end of the fifth assembly part 1125 extends in a direction away from the fourth assembly part 1124; the extension direction of the fifth assembly part 1125 intersects with the extension direction of the fourth assembly part 1124. The third assembly part 1123, the fourth assembly part 1124 and the fifth assembly part 1125 are arranged to form the first clamping groove 112b.

[0054] In this way, the structure of the assembly part 112 can be made simpler, and the difficulty of manufacturing and assembling the assembly part 112 can be reduced.

[0055] In a specific embodiment, as shown in FIG. 2 , the fourth assembly portion 1124 extends along the second direction Y, and the fifth assembly portion 1125 extends along the first direction X. One end of the fourth assembly portion 1124 is connected to an end of the third assembly portion 1123 away from the second assembly portion 1122 , and the other end of the fourth assembly portion 1124 is connected to one end of the fifth assembly portion 1125 .

[0056] In one of the embodiments, as shown in FIG. 1 and FIG. 2 , a limiting protrusion 114 is provided on a side surface of the fixing member 111 and / or the assembly member 112 away from the accommodating cavity 112a. In one example, a limiting protrusion 114 is provided on a side surface of the fixing member 111 away from the accommodating cavity 112a. In another example, a limiting protrusion 114 is provided on a side surface of the assembly member 112 away from the accommodating cavity 112a, and the limiting protrusion 114 is also connected to the fixing member 111. In yet another example, a limiting protrusion 114 is provided on a side surface of the assembly member 112 away from the accommodating cavity 112a, and a limiting protrusion 114 is provided on a side surface of the fixing member 111 away from the accommodating cavity 112a.

[0057] By providing the limiting protrusion 114, when the fixing member 111 is fixed, the limiting protrusion 114 can serve as a reference and positioning role. By making the limiting protrusion 114 abut against the tile hanging strip 2, the fixing member 111 can be quickly positioned, thereby improving the assembly efficiency.

[0058] In one embodiment, the fixing member 111 is provided with an assembly hole 1111. Thus, when installing the fixing member 111, the first fastener 16 can be inserted into the assembly hole 1111 and screwed into the tile hanging strip 2 and / or the flat tile 3.

[0059] In one embodiment, a side surface of the fixing member 111 away from the accommodating cavity 112a is provided with an avoidance groove 1112. It is understandable that the number of the avoidance grooves 1112 can be one or more. By providing the avoidance grooves 1112, on the one hand, it is helpful to save materials, and on the other hand, it is helpful to reduce the adverse effect of the unevenness of the surface of the tile hanging strip 2 / or the flat tile 3 on the assembly of the fixing member 111, so as to facilitate the construction operation.

[0060] In a specific embodiment, avoidance grooves 1112 may be provided on both sides of the assembly hole 1111 along the first direction X.

[0061] In one embodiment, as shown in Figures 1 and 2, a constricted surface 1131 is provided between the cavity wall of the accommodating cavity 112a and a side surface of the fixing member 111 close to the accommodating cavity 112a, and the constricted surface 1131 constitutes the anti-slip mechanism 113. Exemplarily, the constricted surface 1131 may be a curved surface or an inclined plane.

[0062] The necked surface 1131 is formed by smoothly bending the wall of the accommodating cavity 112a and the wall surface at the transition point between the fixing member 111 and the cavity 112a along the second direction Y toward the side close to the photovoltaic tile 12, so as to limit the upper frame 122 of the photovoltaic tile 12 and prevent the upper frame 122 of the photovoltaic tile 12 from escaping from the cavity opening of the accommodating cavity 112a along the first direction X.

[0063] By setting the necked surface 1131, on the one hand, a smooth transition can be achieved between the cavity wall of the accommodating cavity 112a and the side surface of the fixing member 111 close to the accommodating cavity 112a, thereby preventing the photovoltaic tile 12 from being scratched during the assembly process; on the other hand, the volume of the accommodating cavity 112a can be smoothly reduced from the inside to the outside, and after the upper frame 122 is embedded in the accommodating cavity 112a, the risk of the upper frame 122 escaping from the accommodating cavity 112a along the first direction X can be reduced.

[0064] It is understandable that the anti-slip mechanism 113 may also be an anti-slip protrusion. The anti-slip protrusion may be formed by the surface of the fixing member 111 close to the upper frame 122 protruding toward the upper frame 122 along the second direction Y. The specific structure of the anti-slip mechanism 113 is not limited in the embodiment of the present application.

[0065] In one embodiment, the assembly part 112, the fixing part 111 and the anti-slip mechanism 113 are an integrated structure. This is beneficial to reducing the manufacturing difficulty and manufacturing cost of the photovoltaic tile fixing structure 11 on the one hand, and improving the structural strength of the photovoltaic tile fixing structure 11 on the other hand.

[0066] It can be understood that the assembly part 112, the fixing part 111 and the anti-slip mechanism 113 can also be detachably connected, that is, the three are connected in a detachable manner.

[0067] In the second aspect, as shown in FIG3 and FIG4, the embodiment of the present application further provides a photovoltaic tile assembly 1, which includes the photovoltaic tile fixing structure 11 of any embodiment in the first aspect. In addition, the photovoltaic tile assembly 1 also includes a photovoltaic tile 12, and the photovoltaic tile 12 includes a laminate 121, an upper frame 122 and a lower frame 123, and the upper frame 122 and the lower frame 123 are respectively arranged at opposite ends of the laminate 121, wherein the upper frame 122 is embedded in the accommodating cavity 112a of the photovoltaic tile fixing structure 11.

[0068] The photovoltaic tile assembly 1 provided in the embodiment of the present application can install the photovoltaic tile fixing structure 11 on the attachment surface by setting the fixing part 111, and can embed the frame of the photovoltaic tile 12 in the accommodating cavity 112a of the assembling part 112 by setting the assembly part 112, and can prevent the frame of the photovoltaic tile 12 from falling off by setting the anti-slip mechanism 113. In this way, on the one hand, the structure of the photovoltaic tile fixing structure 11 is relatively simple. When assembling the photovoltaic tile 12, it is only necessary to embed the frame of the photovoltaic tile 12 into the accommodating cavity 112a, which is conducive to reducing the difficulty of installing the photovoltaic tile 12; on the other hand, the photovoltaic tile fixing structure 11 can be assembled independently, and the length of the photovoltaic tile fixing structure 11 can be made into a standard length, thereby realizing the standardization of the photovoltaic tile fixing structure 11. Further, when assembling the photovoltaic tile 12, the installation position of the photovoltaic tile fixing structure 11 can be adjusted according to the actual assembly position of the photovoltaic tile 12; on the other hand, the anti-slip mechanism 113 can improve the assembly stability of the photovoltaic tile 12, thereby improving the wind resistance of the photovoltaic tile 12; on the other hand, when the photovoltaic tile 12 needs to be replaced, the upper frame 122 of the photovoltaic tile 12 can be pulled out from the accommodating cavity 112a at a certain angle, thereby helping to realize the independent disassembly and assembly of the photovoltaic tile 12.

[0069] It can be understood that the photovoltaic tile assembly 1 includes a plurality of photovoltaic tiles 12, and the plurality of photovoltaic tiles 12 are stacked in sequence on the roof.

[0070] In one embodiment, as shown in Figure 3, the photovoltaic tile fixing structure 11 shown in Figure 1 is used to fix the photovoltaic tile 12 closest to the ridge (i.e., the photovoltaic tile 12 located at the top of the roof), and the upper frame 122 of the photovoltaic tile 12 is embedded in the accommodating cavity 112a of the photovoltaic tile fixing structure 11.

[0071] In one embodiment, as shown in FIG. 3 , the photovoltaic tile assembly 1 further includes a waterproof member 17 , one end of which contacts the front surface of the laminate 121 , and the other end extends toward the photovoltaic tile fixing structure 11 and covers the photovoltaic tile fixing structure 11 .

[0072] Here, it should be noted that the upper frame 122 and the lower frame 123 of the photovoltaic tile 12 are both long strip structures. The photovoltaic tile fixing structure 11 is a short structural member. When assembling the photovoltaic tile 12, multiple photovoltaic tile fixing structures 11 spaced apart from each other can be assembled in the length direction of the upper frame 122. It can be understood that the length of the waterproof member 17 is not less than the length of the upper frame 122.

[0073] By providing the waterproof component 17, on the one hand, the waterproof component 17 can prevent rainwater from flowing upward from the surface of the laminate 121, thereby improving the waterproof performance of the photovoltaic tile assembly 1; on the other hand, the waterproof component 17 can play a supporting role between the photovoltaic tiles 12 and the flat tiles 3 erected on the photovoltaic tiles 12, thereby ensuring that the photovoltaic tiles 12 stably support the flat tiles 3.

[0074] It is understandable that the waterproof member 17 can also extend to cover the side surface of the photovoltaic tile fixing structure 11 to improve the assembly stability of the waterproof member 17 .

[0075] In one embodiment, as shown in FIG. 4 , the photovoltaic tile fixing structure 11 shown in FIG. 2 is used to fix other photovoltaic tiles 12 (i.e., all photovoltaic tiles 12 except the photovoltaic tile 12 closest to the roof ridge). Specifically, in two adjacent photovoltaic tiles 12, the upper frame 122 of the photovoltaic tile 12 located at the bottom is embedded in the accommodating cavity 112a of the photovoltaic tile fixing structure 11, and the lower frame 123 of the photovoltaic tile 12 located at the top is provided with a lap joint 14, which is snapped into the first snap-in groove 112b, thereby realizing the lap joint connection of the two adjacent photovoltaic tiles 12.

[0076] In one embodiment, the bridging member 14 is provided with a second snap-fitting groove 141, and the groove direction of the first snap-fitting groove 112b is opposite to the groove direction of the second snap-fitting groove 141. Part of the groove body of the first snap-fitting groove 112b extends into the second snap-fitting groove 141, and part of the groove body of the second snap-fitting groove 141 extends into the first snap-fitting groove 112b. In this way, the snap-fitting of the bridging member 14 and the photovoltaic tile fixing structure 11 can be made simpler, reducing the difficulty of assembly.

[0077] In one of the embodiments, the photovoltaic tile fixing structure 11 also includes a limiting member 15, which is detachably disposed on one of the lap joint 14 and the photovoltaic tile fixing structure 11, and limits the clamping portion of the other of the lap joint 14 and the photovoltaic tile fixing structure 11 to keep the lap joint 14 and the photovoltaic tile fixing structure 11 clamped.

[0078] By providing the limiting member 15 , the connection stability between the overlap member 14 and the photovoltaic tile fixing structure 11 can be improved, thereby improving the assembly stability of the photovoltaic tile 12 , and further improving the wind-resistant performance of the photovoltaic tile assembly 1 .

[0079] It should be noted that, when limiting, the limiting member 15 may abut against the clamping portion to be limited, or there may be a small gap between the limiting member 15 and the clamping portion to be limited, so as to prevent the clamping portion to be limited from loosening.

[0080] In one embodiment, as shown in Figures 3 and 4, a shock absorbing member 13 is disposed at the bottom of the upper frame 122, and the shock absorbing member 13 abuts against the cavity wall of the accommodating cavity 112a. Exemplarily, the shock absorbing member 13 is a rubber strip shock absorbing member 13.

[0081] In this way, when the upper frame 122 is embedded in the accommodating cavity 112a, the shock-absorbing member 13 contacts the inner wall of the accommodating cavity 112a, avoiding hard contact between the upper frame 122 and the inner wall of the accommodating cavity 112a, thereby preventing the upper frame 122 from being scratched; in addition, the shock-absorbing member 13 makes the upper frame 122 contact closely with the inner wall of the accommodating cavity 112a, and reduces the vibration noise between the two.

[0082] Please refer to Figures 5 and 6, the installation method of the photovoltaic tile assembly 1 provided in the embodiment of the present application is as follows: first, along the direction from the ridge to the eaves, multiple photovoltaic tile fixing structures 11 are fixed in sequence on different tile hanging strips 2, wherein the photovoltaic tile fixing structure 11 in Figure 2 is located at the top, and the photovoltaic tile fixing structure 11 in Figure 1 is located on the side of the photovoltaic tile fixing structure 11 in Figure 2 close to the eaves.

[0083] For example, taking a photovoltaic tile 12 as an example, the upper frame 122 of the photovoltaic tile 12 is inserted into the accommodating cavity 112a of the photovoltaic tile fixing structure 11 in the horizontal direction, and then the photovoltaic tile 12 is dropped, so that the lap joint 14 on the lower frame 123 is engaged with another photovoltaic tile fixing structure 11, and then the stopper 15 is used to lock it. When disassembling, the stopper 15 is first opened, and then the photovoltaic tile 12 is pushed upward to disengage the lap joint 14 from the photovoltaic tile fixing structure 11, and the photovoltaic tile 12 can be disassembled separately.

[0084] In a third aspect, an embodiment of the present application further provides a rooftop photovoltaic system, comprising the photovoltaic tile assembly 1 of any embodiment in the second aspect.

[0085] The rooftop photovoltaic system provided in the embodiment of the present application can install the photovoltaic tile fixing structure 11 on the attachment surface by setting the fixing part 111, and can embed the frame of the photovoltaic tile 12 in the accommodating cavity 112a of the assembling part 112 by setting the assembly part 112, and can prevent the frame of the photovoltaic tile 12 from falling off by setting the anti-slip mechanism 113. In this way, on the one hand, the structure of the photovoltaic tile fixing structure 11 is relatively simple. When assembling the photovoltaic tile 12, it is only necessary to embed the frame of the photovoltaic tile 12 into the accommodating cavity 112a, which is conducive to reducing the difficulty of installing the photovoltaic tile 12; on the other hand, the photovoltaic tile fixing structure 11 can be assembled independently, and the length of the photovoltaic tile fixing structure 11 can be made into a standard length, thereby realizing the standardization of the photovoltaic tile fixing structure 11. Further, when assembling the photovoltaic tile 12, the installation position of the photovoltaic tile fixing structure 11 can be adjusted according to the actual assembly position of the photovoltaic tile 12; on the other hand, the anti-slip mechanism 113 can improve the assembly stability of the photovoltaic tile 12, thereby improving the wind resistance of the photovoltaic tile 12; on the other hand, when the photovoltaic tile 12 needs to be replaced, the upper frame 122 of the photovoltaic tile 12 can be pulled out from the accommodating cavity 112a at a certain angle, thereby helping to realize the independent disassembly and assembly of the photovoltaic tile 12.

[0086] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.

[0087] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
