Description

Technical Field

[0001] This application relates to the field of building-integrated photovoltaics (BIPV) technology, and in particular to a photovoltaic tile mounting bracket and its installation components, and a photovoltaic roofing system. Background Technology

[0002] Building Integrated Photovoltaics (BIPV) integrates photovoltaic modules as building components or materials, making them part of the building while also generating electricity. BIPV avoids occupying excessive land resources, which is especially important for urban buildings where land is expensive. BIPV converts solar energy into electricity, which can reduce overall outdoor temperature and also play a role in peak shaving for the power grid, thus contributing to building energy conservation.

[0003] In related technologies, there are basically two ways to install photovoltaic roofs. One is a flat structure, which usually requires a large number of bolts for fixing. The installation method is relatively complicated, resulting in low installation efficiency, difficulty in disassembly, and easy damage to the tiles or roof structure during maintenance or replacement. The other is an overlapping structure, in which adjacent photovoltaic tiles are fixed by silicone adhesive. After the silicone ages, the mechanical load-bearing capacity and wind uplift resistance of the photovoltaic tiles may decrease or even fail. Summary of the Invention

[0039] Figure 1 and Figure 2 This is a schematic diagram showing the installation and connection of photovoltaic modules to a building surface according to some embodiments of this application.

[0040] One or more embodiments of this application disclose a mounting bracket for photovoltaic tiles, with reference to... Figures 1 to 4 The mounting bracket 10 is used to fasten to the building surface. The mounting bracket 10 includes a main body 12, a mating part 13, and a partition section 14. The main body 12 is provided with a receiving cavity 124, which is adapted to receive a first frame 30. The mating part 13 is connected to the main body 12 and is provided with a receiving groove 131, which is adapted to receive the bottom of the first frame 30. The opening of the receiving cavity 124 and the opening of the receiving groove 131 are arranged opposite to each other in a first direction. The partition section 14 is connected to the mating part 13 and divides the receiving groove 131 into at least two slots 141 arranged in a second direction, which are adapted to be inserted into the first frame 30.

[0041] It should be understood that the photovoltaic module 1 includes a photovoltaic tile 61, a first frame 30 and / or a second frame 40 disposed around the photovoltaic tile 61, the first frame 30 and / or the second frame 40 supporting the photovoltaic tile 61. A plurality of mounting brackets 10 are spaced apart and fixed to a base plate 92 on a building surface for supporting and connecting the photovoltaic module 1. The building surface includes, but is not limited to, a flat roof, a sloped roof, or a wall. Specifically, one of the first frames 30 of the photovoltaic module 1 is adjustablely installed in the receiving cavity 124 of a mounting bracket 10, enabling rapid installation of the photovoltaic module 1 and improving construction efficiency. The first frame 30 is also adapted to be inserted into the slot 141 of the mating part 13 for installation and fixation of the photovoltaic module 1. Furthermore, another first frame 30 of the photovoltaic module 1 can be limited and engaged with the main body 12 of another mounting bracket 10 along a second direction, facilitating construction while improving the wind uplift resistance of the photovoltaic module 1.

[0042] In some embodiments, refer to Figure 3 and Figure 4 The mounting bracket 10 also includes a fixing part 11 connected to the main body 12. The fixing part 11 and the main body 12 extend in opposite directions, and the fixing part 11 is adapted to be fastened to the installation location. In at least one embodiment, the installation location is implemented as a tile strip 91 fixed to the substrate 92, that is, the fixing part 11 can be installed on the top of the tile strip 91 by fasteners, thereby fixing the mounting bracket 10 to the substrate 92 of the building surface.

[0043] In some embodiments, refer to Figure 3 and Figure 4 The fixing part 11 includes a support section 112 and a first positioning section 113. The support section 112 is connected to the main body part 12. The support section 112 and the main body part 12 extend in opposite directions along a first direction. The first positioning section 113 is connected to the support section 112 and / or the main body part 12. The first positioning section 113 extends toward the installation location. The support section 112 and the first positioning section 113 define a positioning space 111 at the installation location.

[0044] Specifically, refer to Figures 1 to 4 The support section 112 is fixed to the top of the roof tile 91 by the first fastener 101. The first positioning section 113 extends from the support section 112, or from the main body 12, or from the connection between the main body 12 and the support section 112 toward the substrate 92, and the first positioning section 113 is located on one side of the roof tile 91 along the first direction and abuts against the side of the roof tile 91. That is, at least a portion of the roof tile 91 is accommodated in the positioning space 111 between the support section 112 and the first positioning section 113. It is worth mentioning that the first positioning section 113 restricts the rotational freedom of the mounting member 10 relative to the roof tile 91, which helps to prevent the first fastener 101 from loosening when the photovoltaic module 1 shakes.

[0045] In at least one embodiment, the first fastener 101 is implemented as a self-tapping screw to improve the installation efficiency of the hanger 10. Furthermore, the support section 112 is also provided with mounting holes 1121, which limit the first fastener 101, thereby improving the uniformity and standardization of the installation of the first fastener 101 and enhancing the aesthetics of the photovoltaic roof system. Specifically, the first fastener 101 passes sequentially through the support section 112, the tile strip 91, and the substrate 92 of the hanger 10, thereby improving the connection strength and reliability between the hanger 10 and the building surface, and thus improving the structural reliability and wind uplift resistance of the photovoltaic roof system. It should be understood that the material of the substrate 92 includes, but is not limited to, wood, metal, and other penetrating materials.

[0046] In some embodiments, refer to Figure 3 and Figure 4 The fixing part 11 also includes a second positioning section 114, which is connected to the support section 112 and extends toward the installation location. The second positioning section 114 and the first positioning section 113 are spaced apart along a first direction, and a positioning space 111 is defined between the first positioning section 113, the support section 112, and the second positioning section 114. That is, the batten strip 91 can be clamped between the first positioning section 113, the support section 112, and the second positioning section 114, which further restricts the rotational freedom of the connector 10 relative to the batten strip 91 and improves the reliability of the connection between the connector 10 and the batten strip 91.

[0047] In some embodiments, refer to Figures 1 to 4The second positioning segment 114 is fixed to the batten strip 91 by the second fastener 102 to improve the connection strength between the hanger 10 and the batten strip 91. In at least one embodiment, the second fastener 102 is implemented as a self-tapping screw to improve the installation efficiency of the hanger 10. Furthermore, the second positioning segment 114 is also provided with a fixing hole 1141, through which the second fastener 102 can be limited, thereby improving the uniformity and standardization of the installation of the second fastener 102, and also improving the aesthetics of the photovoltaic roof system.

[0048] In some embodiments, refer to Figures 1 to 4 The main body 12 includes a placement section 121, a connecting section 122, and a hooking section 123. The placement section 121 is connected to the fixing section 11, and the placement section 121 and the fixing section 11 extend in opposite directions along a first direction. The connecting section 122 extends upward from the end of the placement section 121 away from the fixing section 11. The hooking section 123 extends from the end of the connecting section 122 away from the placement section 121 toward the second frame 40, and the hooking section 123 can hook with the second frame 40, thereby improving the wind uplift resistance of the photovoltaic module 1. A receiving cavity 124 is defined between the placement section 121, the connecting section 122, and the hooking section 123. A gap 15 is provided between the connecting section 122 and the first frame 30 received in the receiving cavity 124. The gap 15 is suitable for adjustingly installing the first frame 30 in the receiving cavity 124. In other words, the gap 15 allows the first frame 30 to be inserted into or detached from the slot 141 of the mating part 13, so that the photovoltaic module 1 can be detachably connected to the hanger 10, which facilitates the convenient installation, removal or replacement of the photovoltaic module 1.

[0049] In at least one embodiment, reference Figure 2 and Figure 4 The hooking segment 123 extends from the end of the connecting segment 122 away from the placement segment 121 in a turning direction toward the second frame 40, so that the hooking segment 123 can hook with the second frame 40, thereby improving the reliability of the connection between the hooking segment 123 and the second frame 40, which in turn helps to further improve the wind uplift resistance of the photovoltaic module 1.

[0050] In some embodiments, refer to Figure 1 and Figure 2 The photovoltaic tile 61 mounting assembly further includes a spacer 20. It should be understood that the spacer 20 is inserted into the gap 15 between the first frame 30 and the connecting section 122 of the main body 12, so that the first frame 30 is kept connected to the hanger 10, thereby helping to prevent the photovoltaic module 1 from moving along the first direction, thereby reducing the risk of the photovoltaic module 1 accidentally detaching from the hanger 10, and improving the reliability and safety of the photovoltaic roof system.

[0051] It is worth mentioning that when the photovoltaic module 1 needs to be disassembled, the corresponding pad 20 is pulled out, and the photovoltaic module 1 can be refitted to move along the first direction, so that the first frame 30 can be disengaged from the mating part 13. This helps to reduce the difficulty of disassembling the photovoltaic module 1, and makes it easier and faster to disassemble and replace the photovoltaic module 1.

[0052] In some embodiments, refer to Figure 3 and Figure 4 The mating part 13 includes a limiting section 132 and a hooking section 133. The limiting section 132 is connected to the main body 12 and extends upward from the main body 12. The hooking section 133 extends from the end of the limiting section 132 away from the main body 12 toward the connecting section 122. A receiving groove 131 is defined between the hooking section 133, the limiting section 132, and the main body 12. Furthermore, a partition section 14 is connected to the limiting section 132 and extends from the limiting section 132 toward the connecting section 122. The partition section 14 is located between the hooking section 133 and the main body 12, thereby dividing the receiving groove 131 into at least two slots 141 arranged in a second direction.

[0053] In other words, when the first frame 30 is connected to the hanger 10, at least a portion of the hanger 10 can be accommodated in the slot 141 so that the first frame 30 and the hanger 10 are plugged in and fixed. This ensures a reliable connection between the photovoltaic module 1 and the hanger 10, and helps to simplify the installation of the photovoltaic roof system and improve construction efficiency.

[0054] One or more embodiments of this application also disclose an installation assembly for photovoltaic tiles, referring to... Figures 5 to 11 The mounting components include: the aforementioned hanger 10; a first frame 30, which is adjustablely mounted in the receiving cavity 124 of the hanger 10, the first frame 30 having a first mounting portion 34, the first mounting portion 34 being limited to the mating portion 13 of the hanger 10; and a second frame 40, the first frame 30 and the second frame 40 being arranged opposite each other along a first direction, the photovoltaic tile 61 overlapping between the first frame 30 and the second frame 40, the second frame 40 having a second mounting portion 43, the extending directions of the first mounting portion 34 and the second mounting portion 43 being opposite to each other.

[0055] This should be understandable, see reference. Figure 1 , Figure 2 and Figure 6 The first frame 30 is adjustablely installed in the receiving cavity 124 of the hanger 10, enabling rapid installation of the photovoltaic module 1 and thus improving construction efficiency. Furthermore, the first mounting portion 34 of the first frame 30 is confined within the slot 141 of the mating portion 13 for installing and fixing the photovoltaic module 1. Further, referring to… Figure 1 , Figure 2 , Figure 7and Figure 8 The second mounting part 43 of the second frame 40 extends along the photovoltaic tile 61 toward the hanger 10, thereby allowing the second mounting part 43 and the hanger 10 to be matched in a limiting manner along the second direction, which facilitates construction and improves the wind resistance of the photovoltaic module 1.

[0056] In some embodiments, refer to Figure 6 The first frame 30 also includes a first frame portion 31 and a clamping portion 32. The clamping portion 32 is connected to one end of the first frame portion 31 near the photovoltaic tile 61 and extends towards the photovoltaic tile 61 by bending, so as to define a clamping cavity 33 between the clamping portion 32 and the first frame portion 31. The clamping cavity 33 can accommodate the edge of the photovoltaic tile 61. It should be understood that the first frame portion 31 can support the photovoltaic tile 61.

[0057] In some embodiments, refer to Figure 1 , Figure 2 and Figure 6 The first mounting portion 34 includes a plurality of extension segments 341, each extension segment 341 being connected at intervals to one end of the first frame portion 31 away from the clamping portion 32. The extension segments 341 are adapted to be positioned within the slot 141 of the hanger 10. It should be understood that each extension segment 341 is adapted to abut against the hanger segment 133 of the partition segment 14 or the mating portion 13 in the second direction, which helps to improve the connection reliability between the first frame 30 and the hanger 10, thereby improving the wind uplift resistance of the photovoltaic module 1.

[0058] In at least one embodiment, the mounting member 10 includes a partition section 14 disposed on the side of the limiting section 132 near the placement section 121, thereby dividing the receiving groove 131 into two slots 141 of different sizes. Furthermore, the first mounting part 34 includes two extension sections 341, one of which is adapted to be received in the smaller slot 141 to clamp between the partition section 14 and the placement section 121, thereby improving the connection strength between the first frame 30 and the mounting member 10. The other extension section 341 is adapted to be received in the larger slot 141 and abuts against the mounting section 133 in the second direction, which is beneficial for reducing assembly difficulty and improving the wind resistance of the photovoltaic module 1.

[0059] It is worth mentioning that the mounting bracket 10 may also include multiple partition sections 14. Furthermore, the number of extension sections 341 of the first mounting part 34 can match the number of partition sections 14 and mounting sections 133, thereby improving the connection reliability of the first frame 30 and the mounting bracket 10, so as to further improve the wind uplift resistance of the photovoltaic module 1.

[0060] In some embodiments, refer to Figure 6The first frame 30 also includes a first reinforcing rib 35, which is spaced apart within the first frame portion 31 to support the first frame portion 31, thereby improving the structural strength of the first frame 30 and thus improving the load performance of the photovoltaic roof system.

[0061] In some embodiments, refer to Figure 7 and Figure 8 The second frame 40 also includes a second frame portion 41 and a stop edge 42. The stop edge 42 is connected to one end of the second frame portion 41 near the photovoltaic tile 61 and extends upward to abut against the edge of the photovoltaic tile 61. This facilitates positioning the relative positions of the second frame 40 and the photovoltaic tile 61 during installation, reducing assembly difficulty. In addition, it helps to prevent relative sliding between the photovoltaic tile 61 and the second frame 40 along the first direction, thereby improving the structural reliability of the photovoltaic module 1.

[0062] In at least one embodiment, reference Figure 1 and Figure 7 The second mounting portion 43 is connected to the end of the second frame portion 41 near the photovoltaic tile 61 and extends bent towards the hanger 10. Specifically, the second mounting portion 43 includes a first mounting section 431 and a second mounting section 432. The first mounting section 431 extends downward from the upper end of the second frame portion 41, and the second mounting section 432 extends from the end of the first mounting section 431 away from the second frame portion 41 towards the hanger 10, extending below the hook section 123 of the hanger 10 to achieve a limiting fit along the second direction, thereby improving the wind resistance of the photovoltaic module 1.

[0063] In at least one embodiment, reference Figure 2 and Figure 8 The second mounting part 43 is connected to the second frame part 41 and extends in a folded manner toward the hanger 10. Specifically, the second mounting part 43 is connected to the side wall of the second frame part 41 facing the photovoltaic tile 61 and extends in a folded manner toward the hanger 10. Thus, the second mounting part 43 extends into the lower part of the photovoltaic tile 61 of the hanger 10 and hooks with the hook section 123 of the hanger 10, thereby improving the connection reliability between the second frame part 41 and the hanger 10 and further improving the wind uplift resistance of the photovoltaic module 1.

[0064] It should be understood that the second mounting part 43 can be provided along the entire length of the second frame part 41, or it can be provided in sections of the second frame part 41. This application does not impose any specific restrictions on this.

[0065] In some embodiments, refer to Figure 7 and Figure 8The second frame 40 also includes a second frame body portion 41 and a stop edge 42 adhesive placement portion 44. The adhesive placement portion 44 is connected to the end of the second frame body portion 41 away from the stop edge 42, and is adapted to fix the adhesive strip 82. It is worth mentioning that the adhesive strip 82 allows the second frame 40 to make elastic contact with the photovoltaic tile 61 of the adjacent photovoltaic module 1, which helps to avoid damage to the photovoltaic tile 61 caused by the second frame 40.

[0066] In some embodiments, refer to Figure 7 and Figure 8 The second frame 40 also includes a second reinforcing rib 45, which is spaced apart within the second frame portion 41 to support the second frame portion 41, thereby improving the structural strength of the second frame 40 and thus improving the load-bearing performance of the photovoltaic roof system.

[0067] One or more embodiments of this application also disclose a photovoltaic roofing system, see reference Figures 5 to 11 The photovoltaic roof system includes the aforementioned installation components; the photovoltaic module 1 also includes a waterproof frame 51, a drainage frame 52, and a corner bracket 70. The waterproof frame 51 and the drainage frame 52 are arranged opposite each other along a second direction. The waterproof frame 51 is adapted to overlap with the adjacent drainage frame 52. The first frame 30, the waterproof frame 51, the second frame 40, and the drainage frame 52 are adapted to be connected by the corner bracket 70. The photovoltaic tile 61 overlaps between the first frame 30, the waterproof frame 51, the second frame 40, and the drainage frame 52.

[0068] Specifically, when adjacent photovoltaic modules 1 are installed, the waterproof frame 51 of photovoltaic module 1 overlaps with the drainage frame 52 of the adjacent photovoltaic module 1, thereby providing support for both sides of the photovoltaic module 1. It should be understood that the waterproof frame 51 serves to prevent rainwater from entering the gaps between the photovoltaic modules 1, while the drainage frame 52 facilitates the drainage of rainwater from the gaps between the photovoltaic modules 1, thereby reducing water accumulation.

[0069] It is worth mentioning that the materials of the first frame 30, the waterproof frame 51, the second frame 40, and the drainage frame 52 include, but are not limited to, aluminum alloy, steel, polymer resin, and engineering materials. The materials of the first frame 30, the waterproof frame 51, the second frame 40, and the drainage frame 52 can be the same or different, and no specific restrictions are imposed on this.

[0070] In at least one embodiment, reference Figure 6 and Figure 7 The first frame 30, the waterproof frame 51, the second frame 40 and the drainage frame 52 are respectively bonded to the photovoltaic tile 61 with sealant 81, which helps to improve the connection strength and reliability between each frame and the photovoltaic tile 61.

[0071] In some embodiments, refer to Figure 9 The waterproof frame 51 includes a waterproof frame body 511 and a third reinforcing rib 512. The waterproof frame body 511 clamps and supports the photovoltaic tile 61, and the third reinforcing rib 512 is spaced apart inside the waterproof frame to support the waterproof frame body 511. This improves the structural strength of the waterproof frame 51 and thus enhances the load-bearing capacity of the photovoltaic roofing system. Furthermore, when the waterproof frame 51 is struck with a rubber mallet during the installation of the various frames onto the photovoltaic tile 61, the third reinforcing rib 512 prevents the waterproof frame 51 from deforming, which helps improve the yield of the photovoltaic module 1 and reduce production costs.

[0072] In some embodiments, refer to Figure 10 The drainage frame 52 includes a drainage frame body 521 and a fourth reinforcing rib 522. The drainage frame body 521 clamps and supports the photovoltaic tile 61, and the fourth reinforcing rib 522 is spaced apart inside the drainage frame to support the drainage frame body 521. This improves the structural strength of the drainage frame 52, thereby enhancing the load-bearing capacity of the photovoltaic roofing system. Furthermore, when the drainage frame 52 is struck with a rubber mallet during the installation of the various frames onto the photovoltaic tile 61, the fourth reinforcing rib 522 prevents the drainage frame 52 from deforming, which helps improve the yield of the photovoltaic module 1 and reduce production costs.

[0073] For ease of understanding, the specific installation process of photovoltaic module 1 on a sloping roof is described below. It should be understood that photovoltaic module 1 is also suitable for installation on flat roofs, walls, parapets, and other building surfaces:

[0074] A1. Fix the mounting strips 91 to the corresponding positions on the substrate 92 using fasteners, so that the distance between the mounting strips 91 is suitable for installing the photovoltaic module 1.

[0075] A2. When laying photovoltaic module 1, lay it from bottom to top along the roof slope. When laying the first photovoltaic module 1 located at the lowest point of the roof slope, the second mounting part 43 of the second frame 40 at the lower end of the photovoltaic module 1 is placed close to the lower part of the stop of the corresponding hanger 10. Then, the photovoltaic module 1 is moved upward in the first direction so that the first frame 30 at the upper end of the photovoltaic module 1 is accommodated in the receiving cavity 124 of the corresponding hanger 10. Then, relying on its own weight, the photovoltaic module 1 is moved downward in the first direction so that each extension segment 341 of the first mounting part 34 is inserted into the slot 141 of the mating part 13. The first frame 30 is then inserted into the mating part 13. At the same time, the hook segment 123 of the corresponding hanger 10 extends into the photovoltaic tile 61 of the photovoltaic module 1 and the second mounting part 43 of the second frame 40 to achieve a limiting fit in the second direction. The pad 20 is inserted into the gap 15 between the first frame 30 and the connecting segment 122 of the hanger 10. The positive and negative connectors 63 of the junction box 62 of the photovoltaic module 1 are plugged in to complete the wiring connection.

[0076] A3. When laying the next photovoltaic module 1, place the second frame 40 at the lower end of the photovoltaic module 1 on top of the previous photovoltaic module 1, and then move the photovoltaic module 1 upward in the first direction so that the first frame 30 at the upper end of the photovoltaic module 1 is accommodated in the receiving cavity 124 of the corresponding hanger 10. Then, relying on its own weight, the photovoltaic module 1 moves downward in the first direction so that each extension segment 341 of the first mounting part 34 is inserted into the slot 141 of the mating part 13, and the first frame 30 is inserted into the mating part 13. At the same time, the hook segment 123 of the corresponding hanger 10 extends into the photovoltaic tile 61 of the photovoltaic module 1 and the second mounting part 43 of the second frame 40 to achieve a limiting fit in the second direction. Insert the pad 20 into the gap 15 between the first frame 30 and the connecting segment 122 of the hanger 10. Insert the positive and negative connectors 63 of the junction box 62 of the photovoltaic module 1 into each other to complete the wiring connection.

[0077] A4. Then repeat step A3 from bottom to top along the first direction until all photovoltaic modules 1 are laid.

[0078] Furthermore, the disassembly process of the photovoltaic module 1 that needs to be replaced is described:

[0079] B1. Lift the lower end of the photovoltaic module 1 above the photovoltaic module 1 that needs to be replaced, and pull the corresponding pad 20 out of the gap 15.

[0080] B2. Move the photovoltaic module 1 to be replaced upward along the first direction, so that the first mounting part 34 of the first frame 30 of the photovoltaic module 1 to be replaced is separated from the slot 141 of the mating part 13.

[0081] B3. Lift the upper end of the photovoltaic module 1 that needs to be replaced and move it downward in the first direction so that the first frame 30 of the photovoltaic module 1 that needs to be replaced slides out of the receiving cavity 124 of the hanger 10. At the same time, the second mounting part 43 of the second frame 40 of the photovoltaic module 1 that needs to be replaced separates from the stop part of the corresponding hanger 10, thus completing the disassembly.
