[0002] Photovoltaic roof is a new type of environmentally friendly roof that combines photovoltaic panels with metal roofs to achieve photovoltaic building integration. In the prior art, a plurality of photovoltaic tiles adjacent to each other along the slope direction of the roof are connected by connecting components to fix the photovoltaic tiles relative to the roof.

[0003] However, the connection components used between the long frames of adjacent photovoltaic tiles along the slope direction of the roof are mostly snap-fit ​​structures. Due to the limitations of the engagement between the connection components and the photovoltaic tiles and the engagement of the connection components themselves, when any photovoltaic tile is replaced after the roof is installed, it is easy to cause the adjacent photovoltaic tiles to loosen or even fall off. More seriously, it will cause the entire photovoltaic roof to loosen, so it is difficult to replace the photovoltaic tiles connected by the above connection components. Summary of the invention

[0063] Refer to Figure 1, which shows a structural schematic diagram of a photovoltaic tile roof installation and connection system 10 in an embodiment of the present application. The photovoltaic tile roof installation and connection system 10 provided in an embodiment of the present application is used to install multiple photovoltaic tiles 210 along an inclined installation surface 220. The multiple photovoltaic tiles 210 are arranged in sequence along the slope direction OS of the installation surface 220. The photovoltaic tile roof installation and connection system 10 includes multiple groups of hanging devices 100 arranged at intervals along the slope direction OS.

[0064] Referring to FIG. 2 and FIG. 3 , the above-mentioned photovoltaic tile roof installation and connection system 10 includes a mounting seat 110, a mounting assembly 120, a first fastener 130 and a first mounting member 140. The mounting seat 110 is fixed to the mounting surface 220. One end of the mounting assembly 120 is buckled with the back of the lower end of the photovoltaic tile 212 located at the upper part along the slope direction OS of the mounting surface 220, and can be embedded or removed along the first direction OX. The other end of the mounting assembly 120 is buckled with the mounting seat 110, and can be removed or embedded in the mounting seat 110 near one end of the photovoltaic tile 212 located at the upper part along the second direction. The first fastener 130 is detachably fixed to the mounting seat 110 and can abut against the mounting assembly 120 along the first direction OX, so that the mounting assembly 120 abuts against the mounting seat 110 along the first direction OX. One end of the first hanging member 140 is connected to the upper end of the photovoltaic tile 211 at the bottom along the slope direction OS, and the other end of the first hanging member 140 is buckled with the side of the hanging seat 110 away from the photovoltaic tile 212 at the top along the slope direction OS. The first direction OX, the second direction and the thickness direction OZ of the photovoltaic tile are perpendicular to each other, and the first direction OX is the arrangement direction of the plurality of photovoltaic tiles 210.

[0065] When installing multiple photovoltaic tiles 210 using the above-mentioned photovoltaic tile roof installation and connection system 10, first determine the position of a group of hanging devices 100, and describe it by taking the group of hanging components 120 as the lowest group of hanging components 120 along the slope direction OS as an example. First, fix the mounting seat 110 of the lowest mounting assembly 120 to the mounting surface 220, and buckle the lower end of the photovoltaic tile 212 located on the upper part of the group of mounting devices 100 along the slope direction OS of the mounting surface 220 with the mounting seat 110 through the mounting assembly 120. Then, the photovoltaic tile 210 is positioned at the lower photovoltaic tile 211 relative to the adjacent mounting device 100, and the upper end of the photovoltaic tile 210 is buckled with the mounting seat 110 of the adjacent mounting device 100 through the first mounting member 140. The photovoltaic tile 210 is completely mounted between the two groups of mounting devices 100 through the first fastener 130, thereby completing the fixation of the photovoltaic tile 210 along the first direction OX, so that the photovoltaic tile 210 can be fixed relative to the mounting surface 220, and the photovoltaic tile 210 is installed upward along the slope along the mounting surface 220 in sequence according to the above method, thereby completing the installation of the entire photovoltaic roof.

[0066] Referring to Figures 2 and 3, when it is necessary to remove one of the photovoltaic tiles 210, first remove the first fastener 130 adjacent to the lower end of the photovoltaic tile 210, and then use the tool 300 to shake the hanging assembly 120 to loosen the hanging assembly 120 relative to the photovoltaic tile 210 and the hanging seat 110, so that the hanging assembly 120 can be disengaged from the hanging seat 110 along the second direction. At this time, the limit of the lower end of the photovoltaic tile 210 along the first direction OX is released, and then the first hanging member 140 at the upper end of the photovoltaic tile 210 is disengaged from the hanging seat 110 along the first direction OX, so that the photovoltaic tile 210 is completely disassembled. During the process of disassembling the photovoltaic tile 210, the adjacent photovoltaic tiles 210 always maintain a stable limit and are not affected by the disassembly process.

[0067] To reinstall the dismantled photovoltaic tile 210, the disassembly operation is performed in reverse order, that is, the upper end of the photovoltaic tile 210 is buckled with the hanging seat 110 through the first hanging member 140 and abutted along the first direction OX, and then the hanging component 120 is abutted against the lower end of the photovoltaic tile 210, and the hanging component 120 is moved along the first direction OX so that the hanging component 120 and the hanging seat 110 are buckled and abutted along the first direction OX, and finally the hanging component 120 and the hanging seat 110 are tightened by fasteners to complete the re-fixation of the photovoltaic tile 210, so that when a photovoltaic tile 210 needs to be disassembled, repaired and reinstalled, it will not affect other photovoltaic tiles 210 that are working normally, thereby reducing the difficulty of disassembling and replacing the photovoltaic tiles 210.

[0068] Specifically, FIGS. 1-3 are all cross-sectional views with the cross section being perpendicular to the second direction (not shown).

[0069] In one embodiment, the hanging assembly 120 includes a second hanging member 121 and a third hanging member 122. One end of the third hanging member 122 is buckled with the lower back of the photovoltaic tile 212 located at the upper part along the slope direction OS of the mounting surface 220, and can be embedded or removed along the first direction OX, and the other end is buckled with one end of the second hanging member 121. One end of the second hanging member 121 away from the third hanging member 122 is buckled with the hanging seat 110, and can be removed or embedded along the second direction. The first fastener 130 is penetrated through the hanging seat 110 and can abut against the second hanging member 121 along the first direction OX, so that the second hanging member 121 abuts against the hanging seat 110 along the first direction OX. Thus, the third hanging component 122 can be buckled or directly connected to the back of the lower end of the photovoltaic tile 212 located at the top along the slope direction OS of the installation surface 220. During the process of disassembling the photovoltaic tile 210, only the second hanging component 121 buckled with the third hanging component 122 and the hanging seat 110 needs to be moved along the second direction to release the limitation of the lower end of the photovoltaic tile 212 located at the top along the slope direction OS of the installation surface 220 along the first direction OX. During the disassembly process, the photovoltaic tile 210 will not be damaged due to the movement of the hanging component 120 relative to the photovoltaic tile 210, thereby improving the flexibility and stability of disassembly.

[0070] Referring to FIG. 2 and FIG. 3, in one embodiment, the third hanging member 122 includes a first clamping plate 123 extending upward along the slope of the mounting surface 220 and a first slot member 124 opening downward along the slope of the mounting surface 220, the first clamping plate 123 is connected to the photovoltaic tile 212 located at the upper part, and the first clamping plate 123 is connected to the first slot member 124 on the side away from the photovoltaic tile 212 located at the upper part. The hanging seat 110 has a first clamping groove 111 opening toward the photovoltaic tile 212 located at the upper part. The second hanging member 121 has a first connecting member 1211, a first clamping member 1212 and a second clamping member 1213, one end of the first connecting member 1211 is connected to the first clamping member 1212, and the other end is connected to the second clamping member 1213, the first clamping member 1212 is buckled with the first slot member 124, and can be embedded in or out of the first slot member 124 along the first direction OX. The first connecting member 1211 partially extends into the first slot 111, the second clip 1213 is located in the first slot 111 and can be inserted into or removed from the first slot 111 along the second direction, and the first fastener 130 is disposed on the side wall of the first slot 111 and can abut against the second clip 1213 along the first direction OX, so that the second clip 1213 abuts against the inner wall of the first slot 111 along the first direction OX. As shown in Figures 2 and 3, when installing the hanging assembly 120, first connect the first clip plate 123 to the photovoltaic tile 212 located at the upper part, then buckle the first clip 1212 with the first slot member 124 along the first direction OX, move the second clip 1213 along the second direction to insert into the first slot 111, and tighten and abut the second clip 1213 through the first fastener 130, so that the second clip 1213 abuts against the inner wall of the first slot 111 along the first direction OX. , the installation and fixation of the snap-in assembly with the photovoltaic tile 210 and the mounting seat 110 is completed. When disassembly is required, the first fastener 130 is loosened to release the contact with the second snap-in assembly 1213 along the first direction OX, so that the second snap-in assembly 1213 is loosened relative to the first slot 111, and then the second snap-in assembly 1213 is disengaged from the second slot 1231 along the second direction, thereby releasing the first direction OX limit. At this time, the first direction OX limit of the lower end of the photovoltaic tile 210 is released, so that the photovoltaic tile 210 can be disassembled. In this process, the assembly moving along the second direction is the second mounting assembly 121, and the movement along the second direction is completed by the above structure, so the edge of the photovoltaic tile 210 will not be damaged.

[0071] Preferably, the first clamping plate 123 is adhered to the back side of the photovoltaic tile 212 located at the upper part by means of an adhesive portion 155 composed of a double-sided tape and a structural adhesive.

[0072] 2 and 3, in one embodiment, the second clamping member 1213 has a protrusion 1214 protruding away from the bottom wall of the first clamping slot 111 at one end thereof close to the first fastener 130, and the first fastener 130 passes through the side wall of the first clamping slot 111 and abuts against the protrusion 1214. Thus, the abutment area of ​​the second clamping member 1213 for the first fastener 130 is increased, and the abutment failure caused by the slipping of the fastener and the second clamping member 1213 is prevented, and the photovoltaic tile 210 is prevented from shaking.

[0073] Preferably, the side of the second clamping member 1213 close to the first fastener 130 is perpendicular to the axis of the first fastener 130. Alternatively, a groove may be provided on the side of the protrusion 1214 close to the first fastener 130 to facilitate the abutment between the first fastener 130 and the second clamping member 1213 to prevent the two from slipping off.

[0074] Referring to FIG. 2 and FIG. 3 , in one embodiment, the first clamping plate 123 has a supporting portion 125 protruding away from the photovoltaic tile 211 located at the bottom at one end near the edge of the photovoltaic tile 212 located at the top, and the supporting portion 125 abuts against the side surface of the photovoltaic tile 212 located at the top along the first direction OX, and the first clamping plate 123 is connected to the bottom surface of the photovoltaic tile 212 located at the top. Therefore, the photovoltaic tile 210 can be limited along the first direction OX by the supporting portion 125 and the first hanging member 140, so as to fix the photovoltaic tile 210 relative to the installation surface 220.

[0075] Specifically, the hooking device 100 further includes a first sealing gasket 151, one side of which abuts against the photovoltaic tile 212 located at the upper portion, and the other side abuts against the supporting portion 125. Preferably, the first sealing gasket 151 seals the gap between the first clamping plate 123 and the side of the photovoltaic tile 212 located at the upper portion to prevent moisture and external corrosive substances from damaging the photovoltaic tile 210.

[0076] Preferably, the first sealing gasket 151 and the second sealing gasket 152 are both made of rubber gaskets and weather-resistant sealant, and may also be made of other materials, and the specific materials are not limited here.

[0077] Referring to Figures 2 and 3, in one embodiment, the hanging device 100 also includes a water retaining bar 150, one end of the water retaining bar 150 is in contact with the surface of the photovoltaic tile 211 located at the bottom, and the other end is connected to the side of the first clamping plate 123 close to the photovoltaic tile 211 located at the bottom, so that liquids such as rainwater are blocked by the water retaining bar 150, thereby preventing the liquid from corroding the area where the hanging device 100 contacts the photovoltaic tile 210.

[0078] Referring to Fig. 2 and Fig. 3, in one embodiment, the first clamping plate 123 has a second clamping groove 1231 on one side close to the photovoltaic tile 211 at the bottom, and the end of the water retaining strip 150 away from the photovoltaic tile 211 at the bottom is connected to the first clamping plate 123 through the second clamping groove 1231. Since the water retaining strip 150 is generally made of elastic material, such as rubber, etc., it will bend along the surface of the photovoltaic tile 211 at the bottom, and the water retaining strip 150 can be pulled out of the second clamping groove 1231 with a little force, and can be pushed back into the second clamping groove 1231 by hand, so that the photovoltaic tile 210 can be easily replaced later.

[0079] Referring to Figures 2 and 3, in one embodiment, the first clamping plate 123 has a drip eave 126 protruding from the photovoltaic tile 211 located at the bottom at one end near the edge of the upper photovoltaic tile 212. The drip eave 126 and the water retaining strip 150 cooperate to drain rainwater flowing down from the surface of the upper photovoltaic tile 212 smoothly to the surface of the lower photovoltaic tile 211 without entering the interior of the photovoltaic tile 210.

[0080] Referring to Figures 2 and 3, in one embodiment, the mounting seat 110 has a third slot 112 with an opening that slopes downward along the mounting surface 220, and the first mounting member 140 is snap-connected to the mounting seat 110 through the third slot 112, so that the upper end of the photovoltaic tile 211 located at the bottom can be relatively fixed to the mounting seat 110 through the cooperation of the first mounting member 140 and the third slot 112.

[0081] Referring to FIG. 2 and FIG. 3, in one embodiment, the first hanging member 140 includes a second slot member 141 and a third slot member 142 connected to each other, the opening of the second slot member 141 is downward along the slope of the mounting surface 220, and the opening of the third slot member 142 is upward along the slope of the mounting surface 220. The photovoltaic tile 211 located at the bottom is partially located in the second slot member 141 and abuts against the bottom wall of the second slot member 141. The second slot member 141 is partially located in the third slot 112 and abuts against the bottom wall of the third slot 112. A side wall of the third slot 112 close to the mounting surface 220 is partially located in the third slot member 142 and abuts against the bottom wall of the third slot member 142. As shown in Figures 2 and 3, the mutually embedded snap-on mode enables the upper end of the lower photovoltaic tile 211 to be stably hung through the first hanging component 140 and the third slot 112, and can only be removed by moving along the second direction or the first direction OX. The cooperation between the third slot component 142 and the side wall of the third slot 112 prevents the first hanging component 140 from rotating out of the third slot 112.

[0082] 2 and 3, in one embodiment, each group of the hooking devices 100 includes at least two hooking devices 100 arranged at intervals along the second direction. Thus, a ventilation channel can be formed between two adjacent hooking devices 100 arranged at intervals along the second direction, which is convenient for heat dissipation and improves the power generation efficiency of the photovoltaic tile 210.

[0083] Referring to Fig. 2 and Fig. 3, in one embodiment, the hooking device 100 further includes a second sealing pad 152, which is located between the second slot 141 and the photovoltaic tile 211 located at the bottom. The second sealing pad 152 is a rubber pad, which can completely fill the gap between the photovoltaic tile 211 located at the bottom and the second slot 141, and is bonded with a weather-resistant sealant, so that the connection is reliable.

[0084] Referring to FIG. 2 and FIG. 3 , in one embodiment, the hanging device 100 further includes a first flexible strip 153. The first flexible strip 153 is located between the second hanging member 121 and the third hanging member 122. In one embodiment, the hanging device 100 further includes a second flexible strip 154. The second flexible strip 154 ​​is located between the side wall of the third slot 112 and the third slot member 142. The first flexible strip 153 and the second flexible strip 154 ​​can absorb certain deformation and thermal expansion and contraction of the hanging structure, thereby making the hanging structure more stable.

[0085] Referring to FIG. 2 and FIG. 3, in one embodiment, the photovoltaic tile roof installation and connection system 10 further includes a plurality of tile hanging bars 160 arranged at intervals along the slope direction OS, and the hanging device 100 further includes a second fastener 131. The tile hanging bars 160 extend along the second direction, and the plurality of tile hanging bars 160 correspond one-to-one to the plurality of hanging devices 100. The second fastener 131 is penetrated through the hanging seat 110 and the tile hanging bars 160 to connect the hanging seat 110 with the tile hanging bars 160. Thus, a group of hanging devices 100 can be fixed by one tile hanging bar 160, so that the regularity of the hanging process of the photovoltaic tile 210 is standardized by the tile hanging bars 160, so that the disordered installation without reference on the installation surface 220 will not occur.

[0086] Specifically, the mounting seat 110 includes: a second connector 113, a buckle 114, a mounting member 115 and a slot 116, wherein the slot 116 has a first slot 111 opening toward the photovoltaic tile 212 located at the top, one end of the second connector 113 is connected to the side of the slot 116 away from the photovoltaic tile 212 located at the top, and the other end is connected to the mounting member 115, a second fastener 131 is passed through the mounting member 115 and the tile hanging strip 160, one end of the buckle 114 is connected to the middle of the second connector 113, and the buckle 114 and the slot 116 form a third slot 112. Alternatively, the second connector 113 may be directly provided with a third slot 112 opening downwardly along the slope of the mounting surface 220. The buckle 114 is located in the third slot 142.

[0087] 1 , an embodiment of the present application further provides a photovoltaic tile 210 roof 200 , and the photovoltaic tile 210 roof 200 includes: a plurality of photovoltaic tiles 210 and a photovoltaic tile roof installation and connection system 10 .

[0088] Multiple photovoltaic tiles 210 are arranged in sequence along the slope direction OS of the installation surface 220, and a group of hanging devices 100 are used to connect the adjacent photovoltaic tiles 212 located at the upper part and the photovoltaic tiles 211 located at the lower part. One end of the group of hanging devices 100 along the first direction OX is buckled with the back of the lower end of the photovoltaic tile 212 located at the upper part along the slope direction OS of the installation surface 220, and the other end is connected to the upper end of the photovoltaic tile 211 located at the lower part along the slope direction OS of the installation surface 220.

[0089] When installing multiple photovoltaic tiles 210 using the above-mentioned photovoltaic tile roof installation and connection system 10, first determine the position of a group of hanging devices 100, and describe it by taking the group of hanging components 120 as the lowest group of hanging components 120 along the slope direction OS as an example. First, fix the mounting seat 110 of the lowest mounting assembly 120 to the mounting surface 220, and buckle the lower end of the photovoltaic tile 212 located on the upper part of the group of mounting devices 100 along the slope direction OS of the mounting surface 220 with the mounting seat 110 through the mounting assembly 120. Then, the photovoltaic tile 210 is positioned at the lower photovoltaic tile 211 relative to the adjacent mounting device 100, and the upper end of the photovoltaic tile 210 is buckled with the mounting seat 110 of the adjacent mounting device 100 through the first mounting member 140. The photovoltaic tile 210 is completely mounted between the two groups of mounting devices 100 through the first fastener 130, thereby completing the fixation of the photovoltaic tile 210 along the first direction OX, so that the photovoltaic tile 210 can be fixed relative to the mounting surface 220, and the photovoltaic tile 210 is installed upward along the slope along the mounting surface 220 in sequence according to the above method, thereby completing the installation of the entire photovoltaic roof.

[0090] Referring to Figures 2 and 3, when it is necessary to remove one of the photovoltaic tiles 210, first remove the first fastener 130 adjacent to the lower end of the photovoltaic tile 210, and then shake the hanging assembly 120 to loosen the hanging assembly 120 relative to the photovoltaic tile 210 and the hanging seat 110, so that the hanging assembly 120 can be disengaged from the hanging seat 110 along the second direction. At this time, the limit of the lower end of the photovoltaic tile 210 along the first direction OX is released, and then the first hanging member 140 at the upper end of the photovoltaic tile 210 is disengaged from the hanging seat 110 along the first direction OX, so that the photovoltaic tile 210 is completely disassembled. During the process of disassembling the photovoltaic tile 210, the adjacent photovoltaic tiles 210 always maintain a stable limit and are not affected by the disassembly process.

[0091] To reinstall the dismantled photovoltaic tile 210, the disassembly operation is performed in reverse order, that is, the upper end of the photovoltaic tile 210 is buckled with the hanging seat 110 through the first hanging member 140 and abutted along the first direction OX, and then the hanging component 120 is abutted against the lower end of the photovoltaic tile 210, and the hanging component 120 is moved along the first direction OX so that the hanging component 120 and the hanging seat 110 are buckled and abutted along the first direction OX, and finally the hanging component 120 and the hanging seat 110 are tightened by fasteners to complete the re-fixation of the photovoltaic tile 210, so that when a photovoltaic tile 210 needs to be disassembled, repaired and reinstalled, it will not affect other photovoltaic tiles 210 that are working normally, thereby reducing the difficulty of disassembling and replacing the photovoltaic tiles 210.

[0092] Specifically, the tile hanging strip 160 can be made of antiseptic wood, steel, aluminum, or other materials.

[0093] Specifically, one water retaining strip 150 corresponds to a group of hooking devices 100, and one end of the water retaining strip 150 that is away from the photovoltaic tile located at the bottom is sequentially connected to the first clamping plates 123 of the plurality of hooking devices 100, that is, the water retaining strip 150 is a sheet extending along the second direction. The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, all possible combinations of the technical features in the above-mentioned embodiments are not described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
