[0046] In a first aspect, with reference to FIGS. 1, 2 and 3, the present application provides a photovoltaic tile mounting structure which can be used for the installation of a photovoltaic tile 11. For example, the photovoltaic tile mounting structure provided by the present application can be applied to the A node and the B node in FIG. 1.

[0047] Specifically, with reference to FIGS. 2 and 3, the photovoltaic tile mounting structure includes a first frame 111, a second structural member 13 and a first limiting member 14. The first frame 111 is used in conjunction with the second structural member 13. The second structural member 13 is used to be detachably connected with the attachment surface, and the second structural member 13 is provided with a second clamping portion 132 which is detachably connected with the attachment surface. The first limiting member 14 is inserted into the first frame 111 from the outside to the inside, and is used to maintain the connection state of the second clamping portion 132 and the attachment surface.

[0048] Here, the attachment surface can be the flat tile 2, the batten 3 or another photovoltaic tile 11. The first frame 111 and the second structural member 13 can be an integrated structure or a split structure that can be detachably connected.

[0049] In the embodiments of the present application, on the one hand, by arranging the first limiting member 14, the second clamping portion 132 and the attachment surface can be kept in a stable connection state, thereby improving the assembly stability of the photovoltaic tile 11 and the wind resistance of the photovoltaic tile assembly 1; on the other hand, by making the first limiting member 14 pass through the first frame 111 from outside to inside, the first limiting member 14 can be effectively prevented from interfering with other components during assembly, thereby facilitating the assembly of the first limiting member 14.

[0050] In one of the embodiments, the photovoltaic tile mounting structure further comprises a first structural member 12 fixed to the attachment surface, and the first structural member 12 is provided with a first clamping portion 122 matched with the second clamping portion 132. In this way, the second structural member 13 and the attachment surface can be connected through the first structural member 12, thereby facilitating the assembly.

[0051] In this way, during assembly, only the first clamping portion 122 and the second clamping portion 132 need to be clamped to realize the lap joint assembly of the adjacent photovoltaic tiles 11 (or the photovoltaic tile 11 and the flat tile 2), thereby facilitating the lap joint of the photovoltaic tile assembly 1.

[0052] In one of the embodiments, the second structural member 13 is provided with a second mounting portion 131 detachably connected with the first frame 111, and the first limiting member 14 passes through the second mounting portion 131 and abuts against the first clamping portion 122. In this way, the first limiting member 14 passes through the first frame 111 and the second mounting portion 131 and abuts against the first clamping portion 122, which is equivalent to the first limiting member 14 being arranged on the first frame 111 and the second mounting portion 131, thereby improving the assembly stability of the first limiting member 14.

[0053] In one of the embodiments, the first limiting member 14 passes through the first frame 111 and abuts against the first clamping portion 122. In this way, the first limiting member 14 only needs to pass through the first frame 111 to abut against the first clamping portion 122, thereby facilitating the assembly of the first limiting member 14.

[0054] It should be noted here that the abutment of the first limiting member 14 and the first clamping portion 122 can be a close abutment or a small gap therebetween.

[0055] In one of the embodiments, the first frame 111 is provided with a first assembly hole 111a in which the first limiting member 14 is arranged. The second structural member 13 is provided with a second assembly hole 13a, the first assembly hole 111a and the second assembly hole 13a are coaxial, and the first limiting member 14 is arranged in the first assembly hole 111a and the second assembly hole 13a.

[0056] By arranging the first assembly hole 111a on the first frame 111, when the first limiting member 14 is assembled, the first limiting member 14 can be assembled by means of the first assembly hole 111a, so that the first limiting member 14 can be prevented from interfering with other components (for example, the second waterproof member 17) during assembly, thereby facilitating the assembly of the first limiting member 14 and improving the installation efficiency of the photovoltaic tile 11.

[0057] By arranging the second assembly hole 13a, on the one hand, the assembly stability of the first limiting member 14 can be improved, thereby ensuring the limiting effect of the first limiting member 14; on the other hand, referring to FIG. 2, the first limiting member 14 can also limit the first frame 111 and the second structural member 13, and prevent the second structural member 13 from moving relative to the first frame 111 in a direction perpendicular to the paper.

[0058] In one of the embodiments, a threaded pair is arranged between the first limiting member 14 and the first assembly hole 111a. In this way, the first limiting member 14 is threadedly connected with the first frame 111, which facilitates the assembly of the first limiting member 14. In addition, by rotating the first limiting member 14, the abutting tightness of the first limiting member 14 and the first clamping portion 122 can be adjusted to change the clamping tightness of the first clamping portion 122 and the second clamping portion 132.

[0059] In one of the embodiments, a threaded pair is arranged between the first limiting member 14 and the second assembly hole 13a. In this way, the first limiting member 14 is threadedly connected with the second structural member 13, which facilitates the assembly of the first limiting member 14. In addition, by rotating the first limiting member 14, the abutting tightness of the first limiting member 14 and the first clamping portion 122 can be adjusted to change the clamping tightness of the first clamping portion 122 and the second clamping portion 132.

[0060] In one of the embodiments, the first limiting member 14 is a screw or a bolt.

[0061] In one of the embodiments, referring to FIG. 3, the first frame 111 comprises a frame body 1111 and a first assembly part 1112. The frame body 1111 has a hollow cavity. The first assembly part 1112 is arranged at one side of the frame body 1111 close to the second structural member 13, and the second mounting part 131 is connected with the first assembly part 1112. The first assembly hole 111a penetrates the cavity wall of the hollow cavity close to the first assembly part 1112 and the first assembly part 1112, and the second assembly hole 13a penetrates the second mounting part 131.

[0062] It should be noted that the head 141 of the first limiting member 14 (e.g., a screw or a bolt) can move in the hollow cavity along the axial direction of the first limiting member 14. When assembling the first limiting member 14, a tool can be inserted into the hollow cavity to rotate the head of the first limiting member 14 to achieve locking. It should be noted that the head 141 of the first limiting member 14 is the end of the first limiting member 14 away from the first clamping part 122.

[0063] In one of the embodiments, referring to FIG. 3, one of the second mounting part 131 and the first assembly part 1112 is provided with a first clamping protrusion 1311, and the other of the second mounting part 131 and the first assembly part 1112 is provided with a first clamping groove 11121, and the first clamping protrusion 1311 is clamped in the first clamping groove 11121. By arranging the first clamping protrusion 1311 and the first clamping groove 11121, the second mounting part 131 and the first assembly part 1112 can be assembled more stably, and the assembly can be facilitated.

[0064] In a specific embodiment, the first clamping groove 11121 has a structure of "large cavity and small slot", and the first clamping protrusion 1311 is clamped in the cavity of the first clamping groove 11121.

[0065] In one of the embodiments, the first assembly hole 111a communicates with the cavity of the first clamping groove 11121, and the second assembly hole 13a penetrates the first clamping protrusion 1311.

[0066] In one of the embodiments, the first frame 111 is provided with a third assembly hole 111b coaxial with the first assembly hole 111a at the side away from the first assembly part 1112, and the inner diameter of the third assembly hole 111b is larger than that of the first assembly hole 111a. The inner diameter of the third assembly hole 111b is larger than that of the first assembly hole 111a, and the inner diameter of the first assembly hole 111a matches the first limiting member 14. By arranging the third assembly hole 111b, the assembly difficulty of the first limiting member 14 can be reduced.

[0067] Specifically, when assembling the first limiting member 14, the first limiting member 14 can enter from the third assembly hole 111b, and then pass through the first assembly hole 111a and the second assembly hole 13a in sequence to limit the first clamping portion 122. On the one hand, the head 141 of the first limiting member 14 can be accommodated in the third assembly hole 111b, avoiding the head 141 of the first limiting member 14 from leaking out, and on the other hand, an external tool can enter from the third assembly hole 111b to tighten the first limiting member 14, reserving operation space for the tool for tightening the first limiting member 14, for example, the third assembly hole 111b can allow the electric wrench to penetrate the combined part of the first limiting member 14 to ensure that the first limiting member 14 is tightened in place.

[0068] In one embodiment, the first frame 111 further comprises a sealing cover 1113 assembled at the third assembly hole 111b to seal the third assembly hole 111b. By providing the sealing cover 1113, on the one hand, the appearance of the first frame 111 can be improved, and on the other hand, the first limiting member 14 can be protected from corrosion caused by rainwater.

[0069] It can be understood that the material of the sealing cover 1113 can be silica gel or plastic.

[0070] In one embodiment, referring to FIGS. 2, 4 and 5, the first structural member 12 further comprises a first mounting portion 121 and a first extension portion 123. The first mounting portion 121 is used for mounting on the attachment surface. One end of the first extension portion 123 is connected with the first mounting portion 121, and the other end extends away from the first mounting portion 121, and the other end is connected with the first clamping portion 122. By providing the first extension portion 123, the distance between the first clamping portion 122 and the flat tile 2 can be increased, so that after the first limiting member 14 passes through the first frame 111, the first clamping portion 122 can be limited. The height of the first extension portion 123 can match the installation environment of the photovoltaic tile 11, and according to specific installation requirements, a first structural member 12 with a matching height is selected.

[0071] In one embodiment, referring to FIGS. 4 and 5, the first mounting portion 121 comprises a first sub-portion 1211 and a second sub-portion 1212 connected with each other. The first sub-portion 1211 is used for mounting on the attachment surface, and the first extension portion 123 is connected with the second sub-portion 1212. The second sub-portion 1212 is provided with a first accommodating cavity 121a for embedding the frame of the photovoltaic tile 11. In this way, the first structural member 12 can be assembled at the B node to connect two adjacent photovoltaic tiles 11.

[0072] Here, it needs to be explained that the photovoltaic tile 11 can include the first frame 111, the laminated piece 112 and the second frame 113, the first frame 111 is equivalent to the lower frame, and the second frame 113 is equivalent to the upper frame. When assembling the photovoltaic tile 11, the upper frame of the photovoltaic tile 11 can be embedded in the first accommodating cavity 121a.

[0073] Specifically, the first sub-part 1211 can be provided with a through hole for the screw to pass through, and the screw connects the first sub-part 1211 with the attachment surface.

[0074] In one embodiment, referring to FIGS. 3 and 5, the first clamping part 122 is provided with a first groove 1221, the second clamping part 132 is provided with a second groove 1321, the opening direction of the first groove 1221 is opposite to the opening direction of the second groove 1321, part of the groove body of the first groove 1221 extends into the second groove 1321, and part of the groove body of the second groove 1321 extends into the first groove 1221.

[0075] In this way, when the first clamping part 122 and the second clamping part 132 are clamped, the opening direction of the first groove 1221 is opposite to the opening direction of the second groove 1321, and the first clamping part 122 and the second clamping part 132 are moved towards each other, so that part of the groove body of the first groove 1221 extends into the second groove 1321, and part of the groove body of the second groove 1321 extends into the first groove 1221, thereby realizing the clamping of the first clamping part 122 and the second clamping part 132. The assembly process is relatively simple and easy to operate. Further, by applying a force to the first clamping part 122 by the first limiting piece 14 towards the second clamping part 132, the first clamping part 122 and the second clamping part 132 can be locked, and the locking process is relatively simple and easy to operate.

[0076] In one embodiment, the first frame 111 further includes a second waterproof piece 17, and the second waterproof piece 17 is arranged on the side of the frame body 1111 away from the laminated piece 112. By arranging the second waterproof piece 17, rainwater can be prevented from flowing back on the surface of the laminated piece 112.

[0077] It can be understood that the second waterproof piece 17 can be clamped on the frame body 1111.

[0078] In a second aspect, referring to FIG. 1, the embodiment of the present application provides a photovoltaic tile assembly 1, which includes the photovoltaic tile mounting structure in any of the first aspect embodiments.

[0079] The photovoltaic tile assembly 1 provided by the embodiment of the present application can make the second clamping part 132 and the attachment surface keep a stable connection state by arranging the first limiting part 14, improve the assembly stability of the photovoltaic tile 11, and thus improve the wind resistance performance of the photovoltaic tile assembly 1. On the other hand, the first limiting part 14 can be effectively prevented from interfering with other components during assembly by penetrating the first limiting part 14 into the first frame 111 from the outside, and thus the assembly difficulty of the first limiting part 14 can be reduced.

[0080] In one of the embodiments, referring to FIG. 6, the photovoltaic tile assembly 1 further comprises a fixing structure 15, the fixing structure 15 comprises a third mounting part 151 and a second assembly part 152, the third mounting part 151 is arranged on the attachment surface, and the second assembly part 152 is provided with a second accommodating cavity 152a. The third mounting part 151 can be arranged on the flat tile 2 and / or the batten 3, or arranged on the adjacent photovoltaic tile 11.

[0081] Further, the photovoltaic tile assembly 1 further comprises the photovoltaic tile 11, a first waterproof part 16 and a fastener 19. The photovoltaic tile 11 comprises a second frame 113 and a laminated part 112 connected with the second frame 113, the second frame 113 is embedded in the second accommodating cavity 152a, and the second frame 113 is arranged opposite to the first frame 111. The first waterproof part 16 covers the laminated part 112 and the fixing structure 15. The fastener 19 connects the first waterproof part 16 and the fixing structure 15. In one example, the first waterproof part 16 is an L-shaped structure.

[0082] Here, it should be noted that, referring to FIGS. 1 and 7, the photovoltaic tile assembly 1 can comprise a plurality of photovoltaic tiles 11, each photovoltaic tile 11 has the same structure, and each photovoltaic tile 11 comprises a laminated part 112, a first frame 111 and a second frame 113, wherein the first frame 111 is a lower frame, and the second frame 113 is an upper frame. It can be understood that the photovoltaic tile 11 can further comprise a side frame.

[0083] In the embodiment of the present application, the fixing structure 15 is arranged at the position close to the ridge of the roof, and the second frame 113 of the photovoltaic tile 11 at the top of the plurality of photovoltaic tiles 11 arranged in sequence is embedded in the second accommodating cavity 152a. The flat tile 2 is arranged on the first waterproof part 16, and the first waterproof part 16 can prevent the rainwater on the laminated part 112 from flowing back. The assembly stability of the first waterproof part 16 can be improved by connecting the first waterproof part 16 and the fixing structure 15 by the fastener 19.

[0084] In one of the embodiments, the first waterproof part 16 is further provided with a pad 18 at the side close to the laminated part 112, so that the damage of the laminated part 112 caused by the first waterproof part 16 can be prevented.

[0085] The photovoltaic tile assembly 1 provided by the embodiments of the present application can be disassembled by taking off the sealing cover 1113, screwing out the first limiting member 14 by a space, and then pushing the photovoltaic tile 11 upwards to make the first clamping part 122 and the second clamping part 132 disengage, so that the disassembly of the single photovoltaic tile 11 can be completed.
