[0043] In the first aspect, referring to Figures 1, 2, 3 and 4, an embodiment of the present application provides a photovoltaic tile connection structure 13, which can be used in the assembly structure of a photovoltaic tile assembly 1. Further, the photovoltaic tile connection structure 13 can be used to connect a first photovoltaic tile 11 and a second photovoltaic tile 12 erected on the first photovoltaic tile 11.

[0044] Specifically, please refer to Figures 2, 3 and 4, the photovoltaic tile connection structure 13 includes a first connector 131 and a second connector 132. The first connector 131 includes a first assembly portion 1311 and a first clamping portion 1312 connected to the first assembly portion 1311, and the first assembly portion 1311 is connected to the first photovoltaic tile 11. The second connector 132 is arranged on one side of the first connector 131. The second connector 132 includes a second assembly portion 1321 and a second clamping portion 1322 connected to the second assembly portion 1321, the second clamping portion 1322 is clamped with the first clamping portion 1312, and the second assembly portion 1321 is connected to the second photovoltaic tile 12.

[0045] The photovoltaic tile connection structure 13 provided in the embodiment of the present application is provided with a first connector 131 and a second connector 132, wherein the first assembly portion 1311 of the first connector 131 is connected to the first photovoltaic tile 11, the second assembly portion 1321 of the second connector 132 is connected to the second photovoltaic tile 12, and the first clamping portion 1312 of the first connector 131 is clamped with the second clamping portion 1322 of the second connector 132. In this way, on the one hand, the structure of the photovoltaic tile connection structure 13 is relatively simple, and during assembly, only the first clamping portion 1312 and the second clamping portion 1322 need to be clamped to realize the assembly of the first photovoltaic tile 11 and the second photovoltaic tile 12, which is conducive to reducing the installation difficulty of the photovoltaic tile assembly 1; on the other hand, during assembly, the first connector 131 can be connected to the first photovoltaic tile 11, and the second connector 132 can be connected to the second photovoltaic tile 12, and then the first clamping portion 1312 of the first connector 131 can be clamped with the second clamping portion 1322 of the second connector 132 to complete the assembly. In this way, the length of the photovoltaic tile connection structure 13 (the dimension of the photovoltaic tile connection structure 13 perpendicular to the paper surface in Figure 2) can be made into a standard length, thereby realizing the standardization of the photovoltaic tile connection structure 13, and in the actual assembly process, the installation position of the photovoltaic tile connection structure 13 can be adjusted according to the actual assembly position of the photovoltaic tile; on the other hand, when the first photovoltaic tile 11 or the second photovoltaic tile 12 needs to be replaced, the first clamping part 1312 and the second clamping part 1322 of the photovoltaic tile connection structure 13 can be opened, which helps to realize the independent disassembly and assembly of the photovoltaic tiles.

[0046] In one embodiment, the photovoltaic tile connection structure 13 also includes a limiter 133, which is detachably disposed on one of the first connection member 131 and the second connection member 132, and limits the clamping portion of the other of the first connection member 131 and the second connection member 132, so that the first clamping portion 1312 and the second clamping portion 1322 remain clamped.

[0047] By setting a limiting piece 133, the first clamping part 1312 or the second clamping part 1322 can be limited, so that the first clamping part 1312 and the second clamping part 1322 can be stably maintained in a clamping state, thereby improving the clamping stability of the first clamping part 1312 and the second clamping part 1322, thereby improving the assembly stability of the first photovoltaic tile 11 and the second photovoltaic tile 12, and improving the wind-resistant performance of the photovoltaic tile assembly 1.

[0048] It should be noted that, when limiting the position, the limiting member 133 may abut against the clamping portion to be limited, or there may be a small gap between the limiting member 133 and the clamping portion to be limited, so as to prevent the clamping portion to be limited from loosening.

[0049] In one embodiment, the second connecting member 132 further includes a third assembly portion 1323 connected to the second assembly portion 1321, and the limiting member 133 is detachably disposed on the third assembly portion 1323, and limits the first clamping portion 1312. It can be understood that the second assembly portion 1321 and the third assembly portion 1323 can be directly connected, or the connection between the two can be achieved through an intermediate member (such as the base portion 1324 described below).

[0050] In this way, when assembling the first photovoltaic tile 11 and the second photovoltaic tile 12, the first clamping portion 1312 and the second clamping portion 1322 are first clamped, and then the limiting member 133 is assembled on the third assembly portion 1323, and the end of the limiting member 133 is placed in a predetermined limiting position to achieve the purpose of limiting the first clamping portion 1312. Exemplarily, the limiting member 133 can also be brought into contact with the first clamping portion 1312, and a locking force is applied to the first clamping portion 1312, so that the first clamping portion 1312 and the second clamping portion 1322 are locked.

[0051] In one embodiment, as shown in FIG. 3 and FIG. 4 , the second connecting member 132 further includes a base portion 1324, the base portion 1324 having a first end and a second end disposed oppositely along a first direction X, and a first side and a second side disposed oppositely along a second direction Y; the first direction X and the second direction Y intersect, and the first direction X is parallel to the extension direction of the base portion 1324. Specifically, taking the orientation in FIG. 2 as an example, the first end and the second end are respectively opposite ends of the base portion 1324, the first end is the right end of the base portion 1324, and the second end is the left end of the base portion 1324. The first side and the second side are respectively opposite sides of the base portion 1324, the first side is a side of the base portion 1324 close to the first connecting member 131, and the second side is a side of the base portion 1324 away from the first connecting member 131.

[0052] Furthermore, the second clamping portion 1322 is arranged at the first end, and the second assembly portion 1321 and the third assembly portion 1323 are arranged at the second end; the second clamping portion 1322 and the third assembly portion 1323 are located on the first side closer to the first connecting member 131, and the second assembly portion 1321 is located on the second side away from the first connecting member 131.

[0053] The above arrangement can reasonably arrange the positions of the second assembly part 1321, the third assembly part 1323 and the second clamping part 1322. It can be understood that the second laminate 121 of the second photovoltaic tile 12 is located on the second side of the base part 1324. By locating the second clamping part 1322 and the third assembly part 1323 on the first side, the second laminate 121 can be prevented from interfering with the assembly of the stopper 133 during assembly, and the second laminate 121 can be prevented from interfering with the clamping of the first connector 131 and the second connector 132.

[0054] In one embodiment, the third assembly portion 1323 and / or the stopper 133 are provided with a first clamping protrusion 13232, the third assembly portion 1323 and / or the stopper 133 are provided with a first clamping groove 1331, and the first clamping protrusion 13232 is clamped in the first clamping groove 1331. In this way, it is equivalent to clamping the stopper 133 with the third assembly portion 1323, which can reduce the structural complexity of the stopper 133 and the second connecting member 132 on the one hand, and make it more convenient to assemble the stopper 133 with the second connecting member 132 on the other hand.

[0055] In a specific example, as shown in Figure 3, a first clamping protrusion 13232 is provided on one of the third assembly portion 1323 and the limiting member 133, and a first clamping groove 1331 is provided on the other of the third assembly portion 1323 and the limiting member 133, and the first clamping protrusion 13232 is clamped in the first clamping groove 1331.

[0056] 3 , the third assembly portion 1323 is provided with a first engaging protrusion 13232, and the stopper 133 is provided with a first engaging groove 1331. The first engaging groove 1331 is a "large groove cavity and small groove opening" structure, and the first engaging protrusion 13232 is engaged in the groove cavity of the first engaging groove 1331.

[0057] It can be understood that, as shown in FIG. 3 , the first engaging groove 1331 penetrates the limiting member 133 in a direction perpendicular to the paper surface, and during assembly, the first engaging protrusion 13232 is embedded in the first engaging groove 1331 in a direction perpendicular to the paper surface.

[0058] In another specific example, the third assembly part 1323 and the limiting member 133 are both provided with a first clamping protrusion 13232, and the third assembly part 1323 and the limiting member 133 are both provided with a first clamping groove 1331, wherein the first clamping protrusion 13232 on the third assembly part 1323 and the first clamping groove 1331 on the limiting member 133 cooperate with each other, and the first clamping protrusion 13232 on the limiting member 133 and the first clamping groove 1331 on the third assembly part 1323 cooperate with each other.

[0059] It should be noted that after the limiting member 133 is assembled, one end of the limiting member 133 close to the first clamping portion 1312 may abut against the first clamping portion 1312 or have a small gap therebetween, thereby ensuring that the first clamping portion 1312 and the second clamping portion 1322 will not be disengaged.

[0060] In one embodiment, as shown in FIG. 4 , the stopper 133 is disposed along the first direction X and is threadedly engaged with the third assembly portion 1323 .

[0061] In a specific embodiment, as shown in Fig. 4, the third assembly portion 1323 is provided with a first assembly hole 13231, and the stopper 133 is passed through the first assembly hole 13231 and is threadedly connected to the first assembly hole 13231. Exemplarily, the stopper 133 is a bolt or a screw.

[0062] In this way, on the one hand, the structural complexity of the limit member 133 and the second connecting member 132 can be reduced, and on the other hand, the assembly of the limit member 133 and the second connecting member 132 can be made more convenient; on still another hand, the locking degree of the first clamping portion 1312 and the second clamping portion 1322 can be adjusted by adjusting the screw-in depth of the limit member 133, so that the operator can adjust the locking degree of the first clamping portion 1312 and the second clamping portion 1322 according to actual needs.

[0063] In one embodiment, the first engaging portion 1312 is provided with a first engaging slot 13121, and the second engaging portion 1322 is provided with a second engaging slot 13221. The notch of the first engaging slot 13121 is oriented opposite to the notch of the second engaging slot 13221. Part of the first engaging slot 13121 extends into the second engaging slot 13221, and part of the second engaging slot 13221 extends into the first engaging slot 13121.

[0064] Thus, when the first clamping part 1312 and the second clamping part 1322 are clamped, the notch of the first clamping slot 13121 and the notch of the second clamping slot 13221 are opposite to each other, and the first clamping part 1312 and the second clamping part 1322 move toward each other, so that part of the first clamping slot 13121 extends into the second clamping slot 13221, and part of the second clamping slot 13221 extends into the first clamping slot 13121, so that the clamping of the first clamping part 1312 and the second clamping part 1322 can be achieved, and the assembly process is relatively simple and easy to operate. Further, by making the limiting member 133 apply a force toward the second clamping part 1322 to the first clamping part 1312, the first clamping part 1312 and the second clamping part 1322 can be locked, and the locking process is relatively simple and easy to operate.

[0065] In one embodiment, the first assembly part 1311 is provided with a receiving cavity 13111, and the receiving cavity 13111 is used to embed the first upper frame 112 of the first photovoltaic tile 11. In this way, the assembly of the first photovoltaic tile 11 and the first assembly part 1311 can be made simpler, reducing the assembly difficulty.

[0066] In one embodiment, an anti-dropping mechanism is provided at the accommodating cavity 13111 to limit the first upper frame 112 from escaping along the first direction X. In this way, the risk of the first upper frame 112 escaping from the accommodating cavity 13111 can be reduced, and the connection stability between the first upper frame 112 and the first assembly portion 1311 can be improved.

[0067] In one embodiment, the first connecting member 131 further includes a fixing portion 1313, which is used to fix the first connecting member 131; one end of the fixing portion 1313 is connected to the cavity opening of the accommodating cavity 13111, and the other end extends along the first direction X in a direction away from the accommodating cavity 13111.

[0068] In this way, by setting the fixing portion 1313, it is convenient to fix the first connecting member 131 on the installation base. Exemplarily, the fixing portion 1313 can be fixed on the tile hanging bar 2. It should be noted that before assembling the first photovoltaic tile 11, the first connecting member 131 can be fixed on the tile hanging bar 2 by the fixing portion 1313, and then the first upper frame 112 of the first photovoltaic tile 11 is embedded in the accommodating cavity 13111 to realize the assembly of the first photovoltaic tile 11 and the first connecting member 131.

[0069] In one embodiment, the anti-slip mechanism is disposed at the connection between the first assembly portion 1311 and the fixing portion 1313. The wall surface at the connection between the cavity wall of the accommodating cavity 13111 and the fixing portion 1313 is smoothly bent along the second direction Y toward the side close to the first photovoltaic tile 11 to form the anti-slip mechanism. The second direction Y intersects with the first direction X.

[0070] In this way, on the one hand, a smooth transition can be achieved between the cavity wall of the accommodating cavity 13111 and the side surface of the fixing portion 1313 close to the accommodating cavity 13111, thereby preventing the first photovoltaic tile 11 from being scratched during the assembly process; on the other hand, the volume of the accommodating cavity 13111 can be smoothly reduced from the inside to the outside, and after the first upper frame 112 is embedded in the accommodating cavity 13111, the first upper frame 112 can be prevented from escaping from the accommodating cavity 13111 along the first direction X.

[0071] In one embodiment, a necking surface 13131 is provided on a side surface of the fixing portion 1313 close to the accommodating cavity 13111, and the necking surface 13131 is connected to the cavity wall of the accommodating cavity 13111, that is, the necking surface 13131 constitutes an anti-slip mechanism. Exemplarily, the necking surface 13131 can be a curved surface or a flat surface. Specifically, the surface at the connection between the fixing portion 1313 and the accommodating cavity 13111 is smoothly bent along the second direction Y toward the side close to the first photovoltaic tile 11 to form the necking surface 13131.

[0072] It is understandable that the anti-slip mechanism may also be an anti-slip protrusion. The specific structure of the anti-slip mechanism is not limited in the embodiment of the present application.

[0073] In one embodiment, the fixing portion 1313 is provided with a second assembly hole 13132. The second connecting member 132 can be fixed to the tile bar 2 by a second fastener 14. Specifically, the second fastener 14 can be inserted into the second assembly hole 13132 and connected to the tile bar 2.

[0074] In one embodiment, a limiting protrusion 13134 is provided on a surface of a side of the fixing portion 1313 away from the accommodating cavity 13111, and the limiting protrusion 13134 protrudes toward a side close to the first connecting member 131 along the second direction Y. By providing the limiting protrusion 13134, when fixing the second connecting member 132, the limiting protrusion 13134 can serve as a reference and positioning function, and by making the limiting protrusion 13134 abut against the tile hanging strip 2, the fixing portion 1313 can be quickly positioned, thereby improving assembly efficiency.

[0075] In one embodiment, a groove 13133 is provided on the fixing portion 1313 on one side away from the accommodating cavity 13111 along the second direction Y. Exemplarily, the number of the grooves 13133 may be multiple. In a specific embodiment, the grooves 13133 may be evenly arranged on both sides of the second assembly hole 13132. By providing the grooves 13133, 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 on the assembly of the fixing portion 1313.
