[0036] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0037] Example 1

[0038] like Figures 1 to 9 As shown, an embodiment of the present invention provides an installation structure for a photovoltaic module 10, which is used to install the photovoltaic module 10. The installation structure includes a plurality of spaced-apart bases 20. One or more photovoltaic modules 10 are installed between two adjacent bases 20. In a feasible embodiment, the plurality of bases 20 are laid on the installation surface of the roof, such as the surface of a corrugated steel sheet. The plurality of bases 20 can be distributed along a first direction D1. At least one photovoltaic module 10 is fixed between two bases 20. The photovoltaic module 10 can be distributed along a second direction D2. The first direction D1 and the second direction D2 are located in the same plane and are perpendicular to the second direction D2.

[0039] Reference Figures 1 to 4 As shown, the photovoltaic module 10 includes a module body 11 and a frame 12. The frame 12 is located at the edge of the module body 11. The module body 11 contains solar cells to convert light energy into electrical energy. The solar cells have a front surface and a back surface, which are arranged opposite to each other. The front surface is the light-receiving surface facing the direction of sunlight, and the back surface is the surface opposite to the front surface. For bifacial solar cells, the back surface can also be used as a light-receiving surface. If the surface of the solar cells is blocked when fixing the photovoltaic module 10, the photoelectric conversion efficiency will inevitably be reduced.

[0040] Reference Figure 4As shown, the frame 12 includes a first plate 17, a second plate 18, and a clamping part 19. The first plate 17 and the second plate 18 are connected. In one feasible embodiment, the first plate 17 extends along a first direction D1, and the second plate 18 extends along a second direction F2. The clamping part 19 is disposed on at least one side of the second plate 18. The clamping part 19 is used to clamp the component body 11. The clamping part 19 may be composed of two oppositely arranged plates. The gap between the two plates matches the width of the component body 11. Those skilled in the art will know that the structure of the clamping part 19 can be varied, as long as it can clamp and fix the component body 11 stably. No limitation is made here.

[0041] Reference Figure 5 As shown, the base 20 is provided with a second mounting part 21 and a support surface 22. The support surface 22 is used to support the frame 12. The second mounting part 21 and the first mounting part 13 are connected by a connector 30. The support surface 22 plays a supporting role. After the first plate 17 of the frame 12 of the photovoltaic module 10 is placed on the support surface 22, the first mounting part 13 of the frame 12 of the photovoltaic module 10 corresponds to the second mounting part 21 on the base 20, so as to facilitate the connection and fixation of the connector 30. The base 20 is set away from the module body 11 inside the photovoltaic module 10, and the photovoltaic module 10 is suspended between the two bases 20. In this way, the surface of the photovoltaic module 10 will not be blocked, the power generation is increased and its stability is not affected.

[0042] In the embodiments provided in this application, reference continues to be made to... Figure 5 As shown, the base 20 includes a base 23 and a protrusion 24 protruding from the base 23. The base 23 is used to fix to the ground or building surface. The base 23 has a long strip structure. The protrusion 24 protrudes from the surface of the base 23 opposite to the roof. A second mounting part 21 is formed on the protrusion 24. A support surface 22 is formed on the surface of the base 23 located on at least one side of the protrusion 24. The support surface 22 supports the first plate 17 of the frame 12. For the middle base 20, the support surface 22 is formed on the surface of the base 23 located on opposite sides of the protrusion 24. For the edge base 20, the support surface 22 may be formed on the surface of the base 23 located on opposite sides of the protrusion 24. The surfaces of the base 23 on both sides can also be formed on the surface of the base 23 located on one side of the protrusion 24. The second mounting part 21 on the protrusion 24 corresponds to the first mounting part 13 on the frame 12. The photovoltaic module 10 is fixed on two adjacent bases 20. There is no bracket between the two bases 20. During the installation of the photovoltaic module 10, the first plate 17 of the frame 12 is supported by the support surface 22, and the two opposing second plates 18 are clamped by the opposing side walls of the protrusions 24 of the two bases 20, thereby playing a good supporting, clamping and fixing role for the photovoltaic module 10. It is then connected and fixed by the connector 30, and the installation is reliable and has good stability.

[0043] In the embodiments provided in this application, reference is made to Figure 5 , Figure 8 as well as Figure 9 As shown, a protrusion 24 is formed in the middle of the base 23. The extension direction of the protrusion 24 is parallel to the extension direction of the base 23. The protrusion 24 is located in the middle of the base 23. The support surfaces 22 on both sides of the protrusion 24 have a symmetrical structure. The frame 12 of one photovoltaic module 10 is supported on one side support surface 22 of the protrusion 24, and the frame 12 of another photovoltaic module 10 adjacent in the first direction D1 is supported on the other side support surface 22 of the protrusion 24. By centering the protrusion 24, it is convenient for molding and processing and to simultaneously support the frames 12 of two adjacent photovoltaic modules 10.

[0044] Reference Figures 1 to 5 As shown, the first mounting part 13 includes a plurality of first mounting holes 14, and the second mounting part 21 includes a plurality of second mounting holes 25. The plurality of first mounting holes 14 and the plurality of second mounting holes 25 are matched one-to-one. The first mounting holes 14 pass through the second plate 18 of the frame 12, and the second mounting holes 25 pass through the protrusion 24. In one feasible embodiment, the axes of the first mounting holes 14 and the second mounting holes 25 coincide and both extend along the first direction D1. The connector 30 passes through the first mounting holes 14 and the second mounting holes 25 and is fixed to fix the photovoltaic module 10 to the base 20. In another case, refer to Figure 9 As shown, photovoltaic modules 10 are provided on both sides of the base 20 along the first direction D1. The first mounting holes 14 of the two photovoltaic modules 10 correspond one-to-one with the second mounting holes 25 on the protrusion 24. The connector 30 passes through the first mounting hole 14 on one side frame 12, the second mounting hole 25 on the protrusion 24 and the first mounting hole 14 on the other side frame 12 in sequence and is then fixed. Thus, the adjacent side frames 12 of the two photovoltaic modules 10 are fixed to one base 20 at the same time by one connector 30, which saves process and improves efficiency.

[0045] Reference Figures 1 to 5 As shown, the first mounting part 13 includes several sets of first mounting hole groups, which are spaced apart along the length of the frame 12. Each set of first mounting hole groups contains several first mounting holes 14. The number and position of the first mounting hole groups can be determined according to the length of the frame 12 and the overall shape requirements, and are not limited here. By setting multiple sets of first mounting hole groups, the frame 12 can be well fixed. Correspondingly, the second mounting part 21 includes several sets of second mounting hole groups, which are spaced apart along the length of the protrusion 24. Each set of second mounting hole groups contains several second mounting holes 25, and the second mounting holes 25 correspond one-to-one with the first mounting holes 14.

[0046] Reference Figure 6As shown, the connector 30 includes a connecting body 31 and a locking body 32. The connecting body 31 includes a main body segment 311 and a locking segment 312. The main body segment 311 extends sequentially into the first mounting hole 14 and the second mounting hole 25. The locking segment 312 forms a tight fit with the locking body 32 to fix the frame 12 onto the base 20. The outer contour surface of the main body segment 311 is adapted to the inner contour surface of the first mounting hole 14 and the second mounting hole 25. In a feasible embodiment, the outer peripheral surface of the locking segment 312 is provided with an external thread segment. The locking body 32 is a locking nut. The locking nut is threadedly connected and fixed to the locking segment 312, which is secure and convenient and quick to disassemble and assemble.

[0047] In one fixing mode, one side of the frame 12 of the photovoltaic module 10 is supported on the support surface 22 of the base 23, the side of the frame 12 abuts against the side wall of the protrusion 24, the first mounting hole 14 and the second mounting hole 25 are opposite each other, the main body segment 311 of the connecting body 31 passes through the first mounting hole 14 and the second mounting hole 25 in sequence, and the locking segment 312 is threadedly connected to the locking body 32. The other side of the frame 12 of the photovoltaic module 10 is also fixed to another adjacent base 20, thereby fixing a single photovoltaic module 10 to the base 20.

[0048] In another fixing mode, the frame 12 of the photovoltaic module 10 is supported on both sides of the protrusion 24 of the base 20. The first mounting holes 14 of the two photovoltaic modules 10 correspond one-to-one with the second mounting holes 25 on the protrusion 24. After the main body segment 311 passes through the first mounting hole 14 on one frame 12, the second mounting hole 25 on the protrusion 24 and the first mounting hole 14 on the other frame 12 in sequence, the locking segment 312 is threadedly connected to the locking body 32. The other side of the frame 12 of the photovoltaic module 10 is also fixed to the adjacent base 20, thereby fixing the two photovoltaic modules 10 to the base 20, saving processes and improving efficiency.

[0049] In one feasible implementation, refer to Figures 7 to 9 As shown, each group of first mounting holes has two first mounting holes 14; each group of second mounting holes has two second mounting holes 25, corresponding to the above. Figure 6 As shown, the connector 30 includes two connecting bodies 31. The two adjacent connecting bodies 31 are connected by a connecting segment 33. The connector 30 forms a U-shaped structure. When fixed, the connecting segment 33 can also abut against the frame 12, lock the body 32, and clamp the frame 12 and the base 20 to prevent the photovoltaic module 10 from shaking. The fixing stability is good, and the installation is more convenient and quick. Those skilled in the art will know that each group of first mounting holes can not only have two first mounting holes 14, but also a multiple of two. This is not limited here.

[0050] In the embodiments provided in this application, the frame 12 is a cuboid structure, including a first frame 15 and a second frame 16 symmetrically arranged. The first frame 15 and the second frame 16 are located at the long side of the frame 12. The first frame 15 and the second frame 16 are each provided with a first mounting part 13. The first frame 15 and the second frame 16 are each fixed on a base 20, and there is no obstruction between them, which improves the power generation without affecting its stability.

[0051] Example 2

[0052] Reference Figure 10 as well as Figure 11 As shown, the difference between this embodiment and embodiment one is that the base 20 in this embodiment does not have a second mounting hole 25 on the protrusion 24, but is provided with a connecting post 26. One end of the connecting post 26 is fixed to the side wall of the protrusion 24. In one feasible embodiment, the connecting post 26 is symmetrically arranged on opposite sides of the protrusion 24. The end of the connecting post 26 away from the protrusion 24 is provided with an external thread section. The external thread section of the connecting post 26 is threaded with the fastening nut to realize the fixing and release of the frame 12.

[0053] When installing the photovoltaic module 10, the first mounting hole 14 on the frame 12 is aligned with the connecting post 26 and inserted. The bottom of the frame 12 is supported on the support surface 22. The second plate 18 of the frame 12 abuts against the side wall of the protrusion 24. After the connecting post 26 passes through the first mounting hole 13, it is threadedly connected with the fastening nut, which is secure and easy to disassemble and assemble.

[0054] The above description, based on the embodiments shown in the figures, details the structure, features, and effects of the present invention. The above description is only a preferred embodiment of the present invention, but the present invention is not limited to the scope of implementation shown in the figures.
