[0045] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0046] Reference Figure 1 , Figure 1 This diagram illustrates the external structure of a photovoltaic tile connection structure, which includes: a base 1, a first mounting bracket 30, and a second mounting bracket 40. The base 1 is fixedly connected to one end of the first mounting bracket 30; the other end of the first mounting bracket 30 is fixedly connected to one end of the second mounting bracket 40. (Refer to...) Figure 2The other end of the second connector 30 is fixedly connected to the purlin 50, which is used to assemble the photovoltaic tile 60. Slot holes 70 are respectively opened on the column 10, the first connector 20 and the second connector 30. The length extension direction of the slot hole 70 includes: a first direction z perpendicular to the roof, a second direction x parallel to the plane of the roof and a third direction y, wherein the second direction x is perpendicular to the third direction y.

[0047] Optionally, the base 1 includes a column base plate 10 and a column 20. The column base plate 10 is fixedly connected to the roof. One end of the column 20 is fixedly connected to the column base plate 10 and the column 20 is perpendicular to the column base plate 10. The other end of the column 20 is fixedly connected to one end of the first hanging member 30.

[0048] Reference Figure 2 In this embodiment of the utility model, the connecting structure of the photovoltaic tile can be fixedly installed on the roof. The connecting structure of the photovoltaic tile supports the purlin 50, and the purlin 50 further supports the installation of the photovoltaic tile 60. In this way, the photovoltaic tile 60 can be suspended on the roof to form a uniform photovoltaic tile layer. The space between the photovoltaic tile layer and the roof can be used to install the insulation layer, set up the drainage structure, etc.

[0049] Specifically, the connection structure of the photovoltaic tile in this embodiment of the utility model may include: a base 1, a first hook 30, and a second hook 40; wherein, the base 1 can be directly fixedly connected to the roof and play a supporting role. Specifically, the column base plate 10 of the base 1 can be directly attached to the roof and fixedly connected to it by bolts or other fasteners. The column 20 of the base 1 mainly plays a longitudinal supporting role. The first hook 30 and the second hook 40 can be connected to form a hook structure. The hook structure is fixedly connected to the column 20. The purlin 50 is installed on the second hook 40, thus realizing the hanging function of the hook structure.

[0050] Furthermore, in this embodiment of the present invention, the base 1 and the first hook member 30, the first hook member 30 and the second hook member 40, and the second hook member 40 and the purlin 50 can be fixedly connected to each other. In one implementation, the fixed connection can be achieved by the cooperation of bolts and bolt holes. In this embodiment of the present invention, a strip hole 70 is provided as the bolt hole. Since the strip hole 70 has a certain length extension compared to the round hole, the bolt installation is based on the strip hole 70, so that the installation position of the bolt can be adjusted in the length extension direction of the strip hole 70, thereby realizing the position adjustment of the two components in the length extension direction of the strip hole 70. In other implementations, the fixed connection can also adopt a snap-fit ​​connection method using snap-fit ​​members, a plug-in connection method using plug-in members, a snap-fit ​​connection method using fasteners, a crimp connection method using crimping members, etc. This embodiment of the present invention does not limit this.

[0051] In this embodiment of the invention, the length extension directions of the strip holes 70 opened on the base 1, the first hanging member 30, and the second hanging member 40 respectively include: a first direction z perpendicular to the roof surface, a second direction x parallel to the plane where the roof surface is located, and a third direction y, with the second direction x perpendicular to the third direction y. Therefore, this embodiment of the invention can realize the adjustment of the photovoltaic tile connection structure on three axes (first direction z, second direction x, and third direction y), increasing the number of adjustment directions of the photovoltaic tile, improving the adjustment flexibility of the photovoltaic tile, making the installation and leveling of the overall photovoltaic system simpler, ensuring the overall flatness of the photovoltaic tile layer, and improving the stress rationality of the roof power station.

[0052] It should be noted that the connection structure of photovoltaic tiles can be made of stainless steel (such as SUS304 stainless steel). However, when photovoltaic tiles are used in coastal areas, the annual corrosion rate of stainless steel is 128 × 10⁻⁶. -3 The connection structure of the photovoltaic tile can be coated by anodizing, with a coating thickness of 2 mm. -3 mm, corrosion rate is 20mm×10 -3 mm, ensuring stable use of the photovoltaic tile's connection structure throughout its entire lifespan. Furthermore, the exterior of the photovoltaic tile's connection structure can be finished with a black structural layer, paired with anodized blackened purlins and blackened bolts, achieving a uniform appearance and reducing surface corrosion of the connection structure.

[0053] Furthermore, the length of the strip hole can be set to 50mm, ensuring that the adjustment distance of the strip hole is compatible with 0-30mm. In addition, the column base plate and the column can be fixed by single-sided fillet welding (argon arc welding, laser welding), with the fillet weld height less than or equal to 1mm and the weld surface smooth without porosity and slag.

[0054] In summary, the photovoltaic tile connection structure provided by this utility model embodiment includes a base, a first hanger, and a second hanger. This utility model embodiment has strip-shaped holes respectively formed on the base, the first hanger, and the second hanger. The length extension direction of the strip-shaped holes includes: a first direction perpendicular to the roof surface, a second direction parallel to the plane of the roof surface, and a third direction, with the second direction perpendicular to the third direction. This allows for adjustment of the photovoltaic tile connection structure on three axes, increasing the number of adjustment directions for the photovoltaic tile, improving the adjustment flexibility of the photovoltaic tile, simplifying the installation and leveling of the overall photovoltaic system, and ensuring the overall flatness of the photovoltaic tile layer.

[0055] Optional, refer to Figure 3 , Figure 3 A schematic diagram of the external structure of a column is shown. Along the length extension direction z of the column 20, a plurality of first strip holes 71 are provided on the surface of the column 20 at intervals. The length extension direction of the first strip holes 71 is the first direction z.

[0056] In this embodiment of the invention, the cross-section of the column 20 can be a C-shaped structure. In this way, the column 20 not only meets the requirements of support and structural strength, but also has the advantages of lightweight structure and material saving. In this embodiment of the invention, multiple spaced first strip holes 71 are opened on the surface of the column 20, and the length extension direction of the first strip holes 71 is oriented towards the first direction z. When the fixed connection method is bolt connection, the bolt installation between the column 20 and the first connector 30 can be realized based on the first strip holes 71. This allows the installation position of the bolt to be adjusted in different first strip holes 71 and in the length extension direction z of the first strip holes 71. This realizes the position adjustment of the column 20 and the first connector 30 on the coordinate axis of the first direction z, and thus realizes the flexible position adjustment of the purlin 50 and photovoltaic tile 60 supported by the second connector 40 on the coordinate axis of the first direction z.

[0057] Optional, refer to Figure 4 , Figure 4 A schematic diagram of the external structure of a first connector 30 is shown. The first connector 30 includes a first plate 31, a second plate 32, and a third plate 33. One end of the first plate 31 is connected to one end of the second plate 32, and the other end of the second plate 32 is connected to one end of the third plate 33. The third plate 33 is used for fixed connection with a second hanger 40. The first angle formed by the first plate 31 and the second plate 32 is the same as the second angle formed by the second plate 32 and the third plate 33. Preferably, the fixed connection between the third plate 33 and the second hanger 40 can be a bolt connection.

[0058] In this embodiment of the utility model, the first connecting member 30 may include: a first plate 31, a second plate 32, and a third plate 33. The first plate 31 is used to cooperate with the column 20 to realize the fixed installation of the column 20 and the first connecting member 30. The second plate 32 plays a role in lateral extension so that the subsequent installation of the purlin 60 will not interfere with the column 20. The third plate 33 is used to cooperate with the second connecting member 40 to realize the fixed installation of the first connecting member 30 and the second connecting member 40.

[0059] It should be noted that the first angle formed by the first plate 31 and the second plate 32 is the same as the second angle formed by the second plate 32 and the third plate 33. Preferably, the first and second angles are 90 degrees. Furthermore, the connection points between the first plate 31 and the second plate 32, as well as the connection points between the second plate 32 and the third plate 33, can be chamfered to reduce damage caused by the first connector 30 colliding with other components. The first plate 31 and the second plate 32 are both elongated plates, while the third plate 33 can be a rectangular plate. The length of the first plate 31 and the second plate 32 is greater than the length of the third plate 33, and the width of the third plate 33 is greater than the width of the first plate 31 and the second plate 32.

[0060] Optional, refer to Figure 4 Along the length extension direction of the first plate 31, a plurality of spaced second strip holes 72 are provided on the surface of the first plate, and the length extension direction of the second strip holes 72 is the first direction z; the first plate 31 is used to cooperate with the strip holes on the base 1 through the second strip holes 72 to form a fixed connection; a third strip hole 73 is provided on the surface of the third plate 33, and the length extension direction of the third strip hole 73 is the second direction x.

[0061] In this embodiment of the utility model, by opening multiple spaced second strip holes 72 on the surface of the first plate 31, and arranging the multiple second strip holes 72 along the length extension direction y of the first plate 31, with the length extension direction of the second strip holes 72 facing the first direction z, when the fixed connection method is bolt connection, the bolt installation between the column 20 and the first connector 30 can be realized based on the second strip holes 72 on the first plate 31 and the first strip holes 71 on the column 20. This allows the installation position of the bolt to be adjusted in different second strip holes 72 or different first strip holes 71, and also in the length extension direction z of the second strip holes 72 and the first strip holes 71, thereby realizing flexible position adjustment of the column 20 and the first connector 30 on the coordinate axis where the first direction z is located.

[0062] Furthermore, by opening a third strip-shaped hole 73 on the surface of the third plate 33, and with the length extension direction of the third strip-shaped hole 73 being the second direction x, when the fixed connection method is bolt connection, the bolt installation between the third plate 33 and the second connector 40 can be realized based on the third strip-shaped hole 73 on the third plate 33. This allows the installation position of the bolt to be adjusted in the length extension direction x of the third strip-shaped hole 73, realizing flexible position adjustment of the second connector 40 on the coordinate axis where the second direction x is located. In turn, it realizes flexible position adjustment of the purlin 50 and photovoltaic tile 60 carried by the second connector 40 on the coordinate axis where the second direction x is located.

[0063] Optional, refer to Figure 1 The second connector 40 includes a fourth plate 41 and a fifth plate 42; one end of the fourth plate 41 is connected to one end of the fifth plate 42; the fourth plate 41 is perpendicular to the fifth plate 42, and the fourth plate 41 is attached to the third plate 33.

[0064] In this embodiment of the invention, the second connecting member 40 may include a fourth plate 41 and a fifth plate 42. The fourth plate 41 is used to cooperate with the third plate 33 of the first connecting member 30 to achieve fixed installation of the second connecting member 40 and the first connecting member 30. The fifth plate 42 serves to support and install the purlin 60. It should be noted that, preferably, the angle formed by the fourth plate 41 and the fifth plate 42 is 90 degrees. Additionally, the connection position of the fourth plate 41 and the fifth plate 42 can be set as a chamfered structure, which can reduce damage caused by the second connecting member 40 colliding with other components. Both the fifth plate 42 and the fourth plate 41 are elongated plates, with the length of the fifth plate 42 being greater than the length of the fourth plate 41.

[0065] Optional, refer to Figure 1 The fourth plate 41 has a fourth strip hole 74, the length of which extends in the first direction z; the fourth plate 41 is used to cooperate with the third strip hole 73 on the third plate 44 through the fourth strip hole 74 to form a fixed connection; the fifth plate 42 has a fifth strip hole 75, the length of which extends in the third direction y; the fifth plate 42 is used to form a fixed connection with the purlin 50 through the fifth strip hole 75.

[0066] In this embodiment of the invention, when the fourth plate 41 is installed in conjunction with the third plate 33, the position of the fourth plate 41 in the first direction z can be adjusted through the fourth strip hole 74 on the fourth plate 41, whose length extension direction is the first direction z; while when the purlin 50 is installed in conjunction with the fifth plate 42, the position of the purlin 50 in the third direction y can be adjusted through the fifth strip hole 75 on the fifth plate 42, whose length extension direction is the third direction y, thereby realizing flexible position adjustment of the photovoltaic tile 60 carried by the purlin 50 on the coordinate axis of the third direction y.

[0067] In summary, the embodiments of this application achieve flexible adjustment of the three axes (the coordinate axes of the first direction z, the second direction x, and the third direction y) of the photovoltaic tile by setting strip holes (first strip hole 71, second strip hole 72, and fourth strip hole 74) with the length extension direction of the first direction z, strip holes (third strip hole 73) with the length extension direction of the second direction x, and strip holes (fifth strip hole 75) with the length extension direction of the third direction y on the connection structure of the photovoltaic tile.

[0068] Optional, refer to Figure 4 Multiple first sealing grooves 331 with the same orientation are provided on the surface of the third plate 33 facing the fourth plate 41; refer to Figure 1 Multiple second sealing grooves (not shown in the figure) with the same orientation are provided on the surface of the fourth plate 41 facing the third plate 33; when the fourth plate 41 and the third plate 33 are attached, the first sealing groove 331 and the second sealing groove fit together to form a seal.

[0069] In this embodiment of the invention, multiple first sealing grooves 331 with the same orientation are provided on the surface of the third plate 33 facing the fourth plate 41, and corresponding second sealing grooves are provided on the surface of the fourth plate 41 facing the third plate 33. This allows the first sealing grooves 331 and second sealing grooves to fit together and form a waterproof seal when the fourth plate 41 and the third plate 33 are assembled and fitted together. Furthermore, the fit between the first sealing grooves 331 and second sealing grooves increases the assembly firmness between the fourth plate 41 and the third plate 33, reducing the probability of relative rotation between them. The multiple first sealing grooves 331 can be arranged side-by-side on the third plate 33 to form a tooth-like structure, and the second sealing grooves are arranged similarly.

[0070] In another implementation, the surface of the third plate 33 facing the fourth plate 41 and the surface of the fourth plate 41 facing the third plate 33 can be set as rough surfaces, which can achieve the same effect.

[0071] Optional, refer to Figure 1 When the fixed connection method is bolted connection, the bolts used for the fixed connection between the column 20 and the first hanger 30, the bolts used for the fixed connection between the first hanger 30 and the second hanger 40, and the bolts used for the fixed connection between the second hanger 40 and the purlin 50 are all carriage bolts.

[0072] In this embodiment of the utility model, the bolts used to connect the various components in the photovoltaic tile connection structure can be carriage bolts. Carriage bolts are round-headed, square-neck screws, which are important fasteners for connecting two parts with through holes. A carriage bolt consists of a large-area protruding head and a threaded shank, requiring a nut for use. Utilizing the advantages of the carriage bolt's convex structure, combined with a tight-fitting slotted hole end face structure, an extremely secure connection can be ensured.

[0073] Optional, refer to Figure 1 and Figure 5 , Figure 5 A schematic diagram of the external structure of a column base plate is shown. The surface of the column base plate 10 is provided with a plurality of spaced mounting holes 11. The mounting holes 11 include round holes 111 and elongated holes 112. The length of the elongated holes 112 extends in the third direction y.

[0074] In this embodiment of the invention, the column base plate 10 can be a rectangular plate structure. Assembly holes 11 are provided on the column base plate 10 to achieve a fixed connection between the column base plate 10 and the roof by inserting fasteners into the assembly holes 11 and the roof. In practical applications, the roof structure is often complex and varied. Therefore, this embodiment of the invention can provide multiple spaced assembly holes 11 on the surface of the column base plate 10, including circular holes 111 and elongated holes 112 extending in the third direction (y). When a particular assembly hole 11 interferes with the structure on the roof, other assembly holes 11 can be selected for installation. This improves the flexibility of the fastener insertion position. The elongated holes 112 also allow for positional adjustment of the fasteners in the third direction (y), further increasing assembly flexibility.

[0075] Optional, refer to Figure 1 The column base plate 10 is fixedly connected to the roof by inserting chemical anchors into the assembly holes 11 of the column base plate 10 and the roof.

[0076] In this embodiment of the invention, the fasteners used for assembling the column base plate 10 with the roof can be chemical anchors. Specifically, chemical anchors are driven into the assembly holes 11 of the column base plate 10 and the roof to achieve a fixed connection between the column base plate 10 and the roof. The chemical anchors are high-strength anchors made primarily of vinyl resin. They are composite components that use a special chemical adhesive to bond the screw to the drilled hole, thus anchoring the fastener. When the chemical anchor is driven into the roof, the chemical reagent it contains is released and expands, thereby tightly fixing the screw to the inner wall of the hole. Furthermore, the released chemical reagent itself has strong adhesive properties, further increasing the strength of the assembly.

[0077] Optional, refer to Figure 6 The diagram shows another appearance structure of the first connector. The long edge of the first connector 30 is provided with a flange structure 34. The connection between the flange structure 34 and the long edge is a chamfered structure. The extension distance of the flange structure 34 is 1-15mm.

[0078] In this embodiment of the invention, a flange structure 34 can be provided on the long edge of the first connector 30. The extension distance of the flange structure 34 is 1-15mm, and can be any value among 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, and 15mm. The function of the flange structure 34 is to enhance the structural strength of the first connector 30, making the first connector 30 more resistant to pressure and more stable. In addition, the connection between the flange structure 34 and the long edge is a chamfered structure, so that during the installation of the photovoltaic tile, the smooth arc surface of the chamfered structure can reduce the damage caused by bumping the surface of the photovoltaic tile and improve the safety of assembly.

[0079] It should be noted that, Figure 6 The width of the third plate of the first connector 30 shown can be the same as the width of the second plate, and the third plate has a strip hole 70 extending along the first direction z. Further referencing... Figure 7 ,and Figure 6 The fourth plate 41 of the second connecting member 40, which corresponds to the first connecting member 30, can be configured as a wide plate with a width greater than that of the third plate and the fifth plate 43. A strip-shaped hole 70 extending along the second direction x is provided on the fourth plate 41. The strip-shaped hole 70 on the third plate is used to adjust the photovoltaic tile in the first direction z, and the strip-shaped hole 70 on the fourth plate 41 is used to adjust the photovoltaic tile in the second direction x. Furthermore, the surface of the third plate that contacts the fourth plate 41, and the surface of the fourth plate 41 that contacts the third plate, can both be configured as rough surfaces, or have [unclear material]. Figure 4 The sealing groove allows for a waterproof seal when the fourth plate 41 is assembled and fitted with the third plate.

[0080] based on Figure 6 First connector 30 and Figure 7 The second connector 40, when engaged, can form a shape like... Figure 8 The diagram shows another connection structure for photovoltaic tiles. This structure changes the structural form of the first connector 30 and the second connector 40, and can generally achieve flexible adjustment of the photovoltaic tiles on three axes (the first direction z, the second direction x, and the third direction y).

[0081] Reference Figure 2 The present invention provides a photovoltaic system comprising: as shown in the embodiment of the present invention. Figure 1 The photovoltaic tile connection structure, photovoltaic tile 60, and purlin 50 are shown. The photovoltaic tile 60 is fixedly connected to the photovoltaic tile connection structure through the purlin 50. The base 1 in the photovoltaic tile connection structure is fixedly connected to the roof.

[0082] Reference Figure 9 The illustration shows a photovoltaic system applied to a sloping roof 90 according to an embodiment of the present invention. It can be seen that the photovoltaic system of the present invention can be adapted to a sloping roof 90 to meet the requirement of mounting photovoltaic tiles on the sloping roof 90.

[0083] In this embodiment of the invention, the roof can be a sloping roof (90°) or a horizontal roof. Specifically, the roof can be a connecting structural layer for photovoltaic tiles, such as sandwich panels or cement roofing panels. Photovoltaic cells can be embedded inside the photovoltaic tiles. Both sides of the photovoltaic tiles can be covered with cover glass layers, or only the light-facing side can have a cover glass layer. In addition to fulfilling the basic functions of roof tiles, photovoltaic tiles can further achieve the function of photovoltaic power generation.

[0084] In summary, the photovoltaic tile connection structure provided by this utility model embodiment includes a base, a first hanger, and a second hanger. This utility model embodiment has strip-shaped holes respectively formed on the base, the first hanger, and the second hanger. The length extension direction of the strip-shaped holes includes: a first direction perpendicular to the roof surface, a second direction parallel to the plane of the roof surface, and a third direction, with the second direction perpendicular to the third direction. This allows for adjustment of the photovoltaic tile connection structure on three axes, increasing the number of adjustment directions for the photovoltaic tile, improving the adjustment flexibility of the photovoltaic tile, simplifying the installation and leveling of the overall photovoltaic system, and ensuring the overall flatness of the photovoltaic tile layer.
