If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only implementation method.

[0048] In a first aspect, referring to FIGS. 1 , 2 , 3 , 4A and 4B , an embodiment of the present application provides a photovoltaic tile fixing device 14 , which can be used to fix the photovoltaic tiles in the photovoltaic tile assembly 1 .

[0049] Specifically, the photovoltaic tile fixing device 14 includes a first component 141, a second component 142 and a first limiting member 143. The first component 141 includes a first mounting portion 1411 for connecting to the frame of the photovoltaic tile, and a first clamping portion 1412 connected to the first mounting portion 1411 on a side away from the frame. The second component 142 includes a first fixing portion 1421 and a second clamping portion 1422 connected to the first fixing portion 1421, and the first fixing portion is used to be installed on the attachment surface. The second clamping portion 1422 is clamped with the first clamping portion 1412. The first limiting member 143 is detachably arranged on one of the first component 141 and the second component 142, and limits the clamping portion of the other of the first component 141 and the second component 142, so that the first clamping portion 1412 and the second clamping portion 1422 remain clamped.

[0050] It should be noted that the first fixing portion 1421 is used to fix the second member 142, and the first fixing portion 1421 can be fixed on the flat tile 2 and / or the tile hanging strip 3. Exemplarily, the first mounting portion 1411 can be connected to the first lower frame 112 of the lower photovoltaic tile 11, and the second member 142 is arranged on the side of the first member 141 away from the first laminate 111 of the lower photovoltaic tile 11. Before assembling the lower photovoltaic tile 11, first fix the second member 142 on the flat tile 2 and / or the tile hanging strip 3, or, the second member 142 can also be fixed on an adjacent photovoltaic tile. Then, assemble the first member 141 with the first lower frame 112 of the lower photovoltaic tile 11, and then clamp the first clamping portion 1412 of the first member 141 with the second clamping portion 1422 of the second member 142, and finally assemble the first limiter 143, so as to realize the overlapping assembly of the lower photovoltaic tile 11 and the flat tile 2.

[0051] It is understandable that, when limiting, the first limiting member 143 may abut against the clamping portion to be limited, or there may be a small gap between the first limiting member 143 and the clamping portion to be limited, so as to prevent the clamping portion to be limited from loosening.

[0052] In this way, on the one hand, during assembly, it is only necessary to engage the first engaging portion 1412 and the second engaging portion 1422 to realize the overlapping assembly of the lower photovoltaic tile 11 and the flat tile 2, or to realize the overlapping assembly of the lower photovoltaic tile 11 and the adjacent photovoltaic tile. Compared with the prior art, the installation difficulty of the photovoltaic tile assembly 1 is significantly reduced; on the other hand, the photovoltaic tile fixing device 14 can be independently assembled, and the length of the photovoltaic tile fixing device 14 can be made into a standard length, thereby realizing the standardization of the photovoltaic tile fixing device 14. Furthermore, in the actual assembly process, the installation position of the photovoltaic tile fixing device 14 can be adjusted according to the actual assembly position of the lower photovoltaic tile 11; on the other hand, when the lower photovoltaic tile 11 needs to be replaced, the first engaging portion 1412 and the second engaging portion 1422 can be disengaged, thereby facilitating the independent disassembly and assembly of the photovoltaic tiles. By setting the first limiting piece 143, the first component 141 or the second component 142 can be limited, so that the first clamping portion 1412 and the second clamping portion 1422 can be stably maintained in a clamping state, thereby improving the clamping stability of the first clamping portion 1412 and the second clamping portion 1422, thereby improving the assembly stability of the lower photovoltaic tile 11 and improving the wind-resistant performance of the photovoltaic tile assembly 1.

[0053] In one embodiment, as shown in FIG. 4A and FIG. 4B , the first member 141 further includes a first base portion 1414, the first base portion 1414 having a first end and a second end disposed oppositely along a first direction X, and a first side and a second side disposed oppositely along a second direction Y; the first direction X and the second direction Y intersect, and the first direction X is parallel to the extension direction of the first base portion 1414. Specifically, taking the orientation in FIG. 4A and FIG. 4B as an example, the first end is the right end of the first base portion 1414, the second end is the left end of the first base portion 1414, the first side is the lower side of the first base portion 1414, and the second side is the upper side of the first base portion 1414. The first clamping portion 1412 is disposed at the first end, and the first mounting portion 1411 is disposed at the second end; the first clamping portion 1412 and the second member 142 are located on the first side, and the first mounting portion 1411 is located on the second side.

[0054] The above arrangement can reasonably arrange the positions of the first mounting portion 1411 and the first clamping portion 1412. It can be understood that the first laminate 111 of the lower photovoltaic tile 11 is located on the second side of the first base portion 1414. By locating the first clamping portion 1412 and the second mounting portion 1413 on the first side, the first laminate 111 can be prevented from interfering with the assembly of the first stopper 143 during assembly, and the first laminate 111 can be prevented from interfering with the clamping of the first component 141 and the second component 142.

[0055] In one embodiment, the first component 141 further includes a second mounting portion 1413 connected to the first base portion 1414, the second mounting portion 1413 is located at the second end and at the first side. The first limiting member 143 is detachably disposed on the second mounting portion 1413 and limits the second clamping portion 1422.

[0056] In this way, when assembling the lower photovoltaic tile 11, firstly engage the first clamping portion 1412 and the second clamping portion 1422, and then assemble the first limiting member 143 on the second mounting portion 1413, and make the end of the first limiting member 143 be in a predetermined limiting position to achieve the purpose of limiting the second clamping portion 1422.

[0057] In one embodiment, the first limiting member 143 is disposed along the first direction X and is threadedly engaged with the second mounting portion 1413 .

[0058] 4A , the second mounting portion 1413 is provided with a third assembly hole 14131, and the first stopper 143 is passed through the third assembly hole 14131 and threadedly connected to the third assembly hole 14131. Exemplarily, the first stopper 143 is a bolt or a screw.

[0059] In this way, on the one hand, the structural complexity of the first limit piece 143 and the first component 141 can be reduced, and on the other hand, the first limit piece 143 and the first component 141 can be assembled more conveniently; on still another hand, the locking degree of the first clamping portion 1412 and the second clamping portion 1422 can be adjusted by adjusting the screw-in depth of the first limit piece 143, so that the operator can adjust the locking degree of the first clamping portion 1412 and the second clamping portion 1422 according to actual needs.

[0060] In one embodiment, a third clamping protrusion is provided on the second mounting portion 1413 and / or the first limiting member 143, a third clamping groove is provided on the second mounting portion 1413 and / or the first limiting member 143, and the third clamping protrusion is clamped in the third clamping groove.

[0061] In this way, the first limiter 143 is connected to the second mounting portion 1413 , which can reduce the structural complexity of the first limiter 143 and the first component 141 on the one hand, and make the assembly of the first limiter 143 and the first component 141 more convenient on the other hand.

[0062] In one embodiment, a third clamping protrusion (not shown) is provided on one of the second mounting portion 1413 and the first limiting member 143, and a third clamping groove (not shown) is provided on the other of the second mounting portion 1413 and the first limiting member 143, and the third clamping protrusion is clamped in the third clamping groove.

[0063] In another embodiment, a third clamping protrusion is provided on the second mounting portion 1413 and the first limiting member 143, and a third clamping groove is provided on the second mounting portion 1413 and the first limiting member 143. The third clamping protrusion on the second mounting portion 1413 cooperates with the third clamping groove on the first limiting member 143, and the third clamping protrusion on the first limiting member 143 cooperates with the third clamping groove on the second mounting portion 1413.

[0064] In one embodiment, as shown in FIG. 4A , the first fixing portion 1421 extends along the first direction X, and the second clamping portion 1422 is disposed at an end of the first fixing portion 1421 away from the first mounting portion 1411. The second clamping portion 1422 is in an F shape.

[0065] In one embodiment, referring to FIG. 4B , the second component 142 further includes a third mounting portion 1423, and the third mounting portion 1423 and the second clamping portion 1422 are arranged on a side of the first fixing portion 1421 close to the first component 141, and the third mounting portion 1423 and the second clamping portion 1422 are spaced apart; the first limiting member 143 is detachably arranged on the third mounting portion 1423, and limits the second clamping portion 1422.

[0066] Thus, when assembling the lower photovoltaic tile 11, firstly, the first clamping portion 1412 and the second clamping portion 1422 are clamped, and then the first limiting member 143 is assembled on the third mounting portion 1423, and the end of the first limiting member 143 is placed in a predetermined limiting position, so as to limit the first clamping portion 1412. Furthermore, along the first direction X, the overlapped portions of two adjacent photovoltaic tiles maintain a stable assembly state.

[0067] In one embodiment, the first limiting member 143 is disposed along the first direction X and is threadedly engaged with the third mounting portion 1423 .

[0068] In this way, on the one hand, the structural complexity of the first limit member 143 and the second component 142 can be reduced, and on the other hand, the first limit member 143 and the second component 142 can be assembled more conveniently; on still another hand, the locking degree of the first clamping portion 1412 and the second clamping portion 1422 can be adjusted by adjusting the screw-in depth of the first limit member 143, so that the operator can adjust the locking degree of the first clamping portion 1412 and the second clamping portion 1422 according to actual needs.

[0069] In one embodiment, a third clamping protrusion is provided on the third mounting portion 1423 and / or the second clamping portion 1422, and a third clamping groove is provided on the third mounting portion 1423 and / or the second clamping portion 1422. The third clamping protrusion on the third mounting portion 1423 cooperates with the third clamping groove on the first limiting member 143, and the third clamping protrusion on the first limiting member 143 cooperates with the third clamping groove on the third mounting portion 1423.

[0070] In one embodiment, as shown in FIG. 4B , the first fixing portion 1421 extends along the first direction X, and the second clamping portion 1422 and the third mounting portion 1423 are respectively disposed at two ends of the first fixing portion 1421. The second clamping portion 1422 is L-shaped, and the second clamping portion 1422 and the first fixing portion 1421 are jointly arranged to form a second groove 14221.

[0071] In one embodiment, a first groove 14121 is provided on the first clamping portion 1412, and a second groove 14221 is provided on the second clamping portion 1422. The notch direction of the first groove 14121 is opposite to the notch direction of the second groove 14221; part of the groove body of the first groove 14121 extends into the second groove 14221, and part of the groove body of the second groove 14221 extends into the first groove 14121.

[0072] In this way, when the first clamping part 1412 and the second clamping part 1422 are clamped, the notch of the first groove 14121 is oriented opposite to the notch of the second groove 14221, and the first clamping part 1412 and the second clamping part 1422 move toward each other, so that part of the groove body of the first groove 14121 extends into the second groove 14221, and part of the groove body of the second groove 14221 extends into the first groove 14121, so that the clamping of the first clamping part 1412 and the second clamping part 1422 can be achieved, and the assembly process is relatively simple and easy to operate. Further, by making the first limiter 143 apply a force toward the second clamping part 1422 to the first clamping part 1412, the first clamping part 1412 and the second clamping part 1422 can be locked, and the locking process is relatively simple and easy to operate.

[0073] In the second aspect, as shown in Figures 1 and 2, an embodiment of the present application provides a photovoltaic tile assembly 1, which can be installed on a roof 4. The photovoltaic tile assembly 1 includes a photovoltaic tile fixing device 14 in any embodiment of the first aspect.

[0074] Specifically, the photovoltaic tile assembly 1 also includes a lower photovoltaic tile 11, which includes a first laminate 111 and a first lower frame 112 arranged on the first laminate 111; the photovoltaic tile fixing device 14 is arranged on the back side of the first laminate 111, and the first lower frame 112 is connected to the first mounting portion 1411 of the photovoltaic tile fixing device 14. It can be understood that the first lower frame 112 and the first mounting portion 1411 can be an integrated structure or can be detachably connected.

[0075] In this way, on the one hand, when assembling the lower photovoltaic tile 11, it is only necessary to engage the first clamping portion 1412 and the second clamping portion 1422 to achieve the overlapping assembly of the lower photovoltaic tile 11 and the flat tile 2, which is beneficial to reduce the installation difficulty of the photovoltaic tile assembly 1; on the other hand, the photovoltaic tile fixing device 14 can be assembled independently, and the length of the photovoltaic tile fixing device 14 can be made into a standard length, thereby achieving the standardization of the photovoltaic tile fixing device 14. Further, in the actual assembly process, the installation position of the photovoltaic tile fixing device 14 can be adjusted according to the actual assembly position of the lower photovoltaic tile 11; on the other hand, when the lower photovoltaic tile 11 needs to be replaced, the first clamping portion 1412 and the second clamping portion 1422 can be disengaged, thereby facilitating the independent disassembly and assembly of the photovoltaic tiles. By setting the first limiting piece 143, the first component 141 or the second component 142 can be limited, so that the first clamping portion 1412 and the second clamping portion 1422 can be stably maintained in a clamping state, thereby improving the clamping stability of the first clamping portion 1412 and the second clamping portion 1422, thereby improving the assembly stability of the lower photovoltaic tile 11 and improving the wind-resistant performance of the photovoltaic tile assembly 1.

[0076] In one embodiment, as shown in FIG3 , a first waterproof member 114 is provided on a side of the first lower frame 112 away from the first laminate 111. By providing the first waterproof member 114 on a side of the first lower frame 112 away from the first laminate 111, rainwater can be prevented from flowing back at the bottom of the first lower frame 112, thereby improving the waterproof performance of the photovoltaic tile assembly 1.

[0077] In one embodiment, as shown in FIG3 , the distance between one end of the first waterproof member 114 away from the first laminate 111 and the front surface of the first laminate 111 is not less than the distance between one side of the first fixing portion 1421 away from the first laminate 111 and the front surface of the first laminate 111. In FIG3 , the distance between one end of the first waterproof member 114 away from the first laminate 111 and the front surface of the first laminate 111 is equal to the distance between one side of the first fixing portion 1421 away from the first laminate 111 and the front surface of the first laminate 111, and both are equal to H.

[0078] It should be noted that the surface of one side of the first fixing portion 1421 away from the first laminate 111 is in contact with the surface of the flat tile 2 or the photovoltaic tile, and the distance between the side of the first fixing portion 1421 away from the first laminate 111 and the front of the first laminate 111 is equal to the distance between the surface of the flat tile 2 and the front of the first laminate 111. By making the distance between one end of the first waterproof component 114 away from the first laminate 111 and the front of the first laminate 111 not less than the distance between the side of the first fixing portion 1421 away from the first laminate 111 and the front of the first laminate 111, it can be ensured that the first waterproof component 114 can be in contact with the surface of the flat tile 2 after assembly, thereby preventing rainwater from flowing upward along the surface of the flat tile 2, thereby playing a waterproof role.

[0079] In one embodiment, one of the first lower frame 112 and the first waterproof member 114 is provided with a first snap-fitting protrusion 1141, and the other of the first lower frame 112 and the first waterproof member 114 is provided with a first snap-fitting groove 1123, and the first snap-fitting protrusion 1141 is snap-fitted into the first snap-fitting groove 1123. Exemplarily, the material of the first waterproof member 114 can be rubber or silicone. In this way, on the one hand, it is convenient to assemble the first waterproof member 114 and the first lower frame 112, and on the other hand, it can improve the assembly stability of the first waterproof member 114 and the first lower frame 112.

[0080] In a specific embodiment, the first lower frame 112 is provided with a first engaging groove 1123, and the first waterproof member 114 is provided with a first engaging protrusion 1141. The first engaging groove 1123 is a "large groove cavity and small groove opening" structure, and the first engaging protrusion 1141 is engaged in the groove cavity of the first engaging groove 1123.

[0081] It can be understood that, as shown in FIG. 3 , the first engaging groove 1123 penetrates the first lower frame 112 in a direction perpendicular to the paper surface, and during assembly, the first engaging protrusion 1141 is embedded in the first engaging groove 1123 in a direction perpendicular to the paper surface.

[0082] In one embodiment, referring to FIG. 3 , the first lower frame 112 includes a first lower frame body 1121 and a first stop portion 1122. A mounting surface (not shown) is provided on one side of the first lower frame body 1121 close to the first laminate 111. One end of the first stop portion 1122 is connected to the mounting surface, and the other end of the first stop portion 1122 extends in a direction away from the mounting surface.

[0083] The first laminate 111 is disposed on the assembly surface, and the distance between the end of the first stopper 1122 away from the assembly surface and the assembly surface is less than or equal to the distance between the front surface of the first laminate 111 and the assembly surface. That is, the height of the end of the first stopper 1122 away from the assembly surface is less than or equal to the height of the front surface of the first laminate 111.

[0084] In this way, rainwater is helpful to wash away dust on the first laminate 111 , thereby preventing dust from accumulating on the front side of the first laminate 111 .

[0085] In one embodiment, as shown in FIG. 3 , one of the first lower frame 112 and the first mounting portion 1411 is provided with a second engaging protrusion 14111, and the other of the first lower frame 112 and the first mounting portion 1411 is provided with a second engaging groove 1124, and the second engaging protrusion 14111 is engaged with the second engaging groove 1124. In this way, the first member 141 and the first lower frame 112 are engaged with each other, which can reduce the structural complexity of the first member 141 and the first lower frame 112 on the one hand, and make the assembly of the first member 141 and the first lower frame 112 more convenient on the other hand.

[0086] In a specific embodiment, as shown in FIG3 and FIG4A , a second engaging groove 1124 is provided on the first lower frame 112, and a second engaging protrusion 14111 is provided on the first mounting portion 1411. The second engaging groove 1124 is a "large groove cavity and small groove opening" structure, and the second engaging protrusion 14111 is engaged in the groove cavity of the second engaging groove 1124.

[0087] It can be understood that, as shown in FIG. 3 , the second snap-fitting groove 1124 penetrates the first lower frame 112 in a direction perpendicular to the paper surface, and during assembly, the second snap-fitting protrusion 14111 is embedded in the second snap-fitting groove 1124 in a direction perpendicular to the paper surface.

[0088] In one embodiment, the photovoltaic tile assembly 1 further includes a first fastener 161, a first mounting hole (not shown) is provided on the first mounting portion 1411, a second mounting hole (not shown) is provided on the first fastener 161, and the first fastener 161 is passed through the first mounting hole and the second mounting hole. In this way, the assembly stability of the first member 141 and the first lower frame 112 can be further improved.

[0089] In one embodiment, as shown in FIG. 2 and FIG. 5 , the photovoltaic tile assembly 1 further includes a third component 17 and an upper photovoltaic tile 12. The third component 17 includes a main body 171 and a fourth mounting portion 172, the main body 171 is provided with a first accommodating cavity 1711, one end of the fourth mounting portion 172 is connected to the cavity opening of the first accommodating cavity 1711, and the other end extends in a direction away from the first accommodating cavity 1711; the fourth mounting portion 172 is used to fix the third component 17. The upper photovoltaic tile 12 includes a second laminate 121 and a second upper frame 122 arranged on the second laminate 121; the second upper frame 122 is embedded in the first accommodating cavity 1711. Exemplarily, the fourth mounting portion 172 can be fixed on the flat tile 2 and / or the tile hanging strip 3.

[0090] Thus, before assembling the upper photovoltaic tile 12, the third component 17 can be fixed to the flat tile 2 and / or the tile hanging strip 3 through the fourth mounting portion 172, and then the second upper frame 122 of the upper photovoltaic tile 12 is embedded in the first accommodating cavity 1711 to realize the assembly of the upper photovoltaic tile 12 and the third component 17. The above arrangement can make the assembly of the upper photovoltaic tile 12 and the third component 17 relatively simple and reduce the assembly difficulty. It is understandable that the third component 17 can also support the flat tile 2 overlapped on the upper photovoltaic tile 12.

[0091] Exemplarily, the fourth mounting portion 172 may be assembled on the tile batten 3 via the third fastener 163 .

[0092] In one embodiment, a second shock absorbing member 125 is disposed at the bottom of the second upper frame 122, and the second shock absorbing member 125 abuts against the cavity wall of the first accommodating cavity 1711. Exemplarily, the second shock absorbing member 125 is a rubber strip shock absorbing member.

[0093] In this way, when the second upper frame 122 is embedded in the first accommodating cavity 1711, the second shock-absorbing member 125 contacts the inner wall of the first accommodating cavity 1711, avoiding hard contact between the second upper frame 122 and the inner wall of the first accommodating cavity 1711, thereby preventing the second upper frame 122 from being scratched; in addition, the second shock-absorbing member 125 makes the second upper frame 122 in close contact with the inner wall of the first accommodating cavity 1711, and reduces the vibration noise between the two.

[0094] In one embodiment, as shown in FIG. 6 , a first necked surface 1723 is provided between the cavity wall of the first accommodating cavity 1711 and a side surface of the fourth mounting portion 172 close to the first accommodating cavity 1711. Exemplarily, the first necked surface 1723 may be a curved surface or a flat surface. The first necked surface 1723 is formed by smoothly bending the wall surface at the transition point between the cavity wall of the first accommodating cavity 1711 and the fourth mounting portion 172 along the second direction Y toward the side close to the upper photovoltaic tile 12, so as to limit the second upper frame 122 of the upper photovoltaic tile 12, and prevent the second upper frame 122 of the upper photovoltaic tile 12 from escaping from the cavity opening of the accommodating cavity 1711 along the first direction X. The second shock-absorbing member 125 increases the friction between the second upper frame 122 and the cavity wall, and enhances the limiting effect on the second upper frame 122.

[0095] By setting the first necked surface 1723, on the one hand, a smooth transition can be achieved between the cavity wall of the first accommodating cavity 1711 and the side surface of the fourth mounting portion 172 close to the first accommodating cavity 1711, thereby preventing the upper photovoltaic tile 12 from being scratched during the assembly process; on the other hand, the volume of the first accommodating cavity 1711 can be smoothly reduced from the inside to the outside, and after the second upper frame 122 is embedded in the first accommodating cavity 1711, the risk of the second upper frame 122 escaping from the first accommodating cavity 1711 can be reduced.

[0096] In one embodiment, a fourth assembly hole 1724 is provided on the fourth mounting portion 172. The fourth component 181 can be fixed to the tile bar 3 by the second fastener 162. Specifically, the second fastener 162 can be inserted into the fourth assembly hole 1724 and connected to the tile bar 3.

[0097] In one embodiment, a first limiting protrusion 1722 is provided on a side surface of the fourth mounting portion 172 away from the first accommodating cavity 1711. By providing the first limiting protrusion 1722, when the third member 17 is fixed, the first limiting protrusion 1722 can serve as a reference and positioning function, and by making the first limiting protrusion 1722 abut against the tile hanging strip 3, the fourth mounting portion 172 can be quickly positioned, thereby improving assembly efficiency.

[0098] In one embodiment, the fourth mounting portion 172 is provided with a third groove 1721. Exemplarily, the number of the third grooves 1721 can be multiple. In a specific embodiment, the third grooves 1721 can be evenly arranged on both sides of the fourth assembly hole 1724. By providing the third grooves 1721, on the one hand, it is helpful to save materials, and on the other hand, it is helpful to reduce the adverse effect of the unevenness of the surface of the tile hanging strip 3 on the assembly of the fourth mounting portion 172.

[0099] In one embodiment, as shown in FIG. 5 , the photovoltaic tile assembly 1 further includes a second waterproof member 15 , one end of which contacts the front surface of the second laminate 121 , and the other end extends toward the third component 17 and covers the third component 17 .

[0100] Here, it should be noted that the second upper frame 122 and the second lower frame 123 of the upper photovoltaic tile 12 are both long strip structures. The first upper frame 113 and the first lower frame 112 of the lower photovoltaic tile 11 are both long strip structures. The first component 141, the second component 142 and the third component 17 are all short structural parts. Taking the third component 17 and the second upper frame 122 as an example, during assembly, multiple third components 17 spaced apart from each other can be assembled in the length direction of the second upper frame 122. It can be understood that the length of the second waterproof component 15 is not less than the length of the second upper frame 122.

[0101] By providing the second waterproof component 15, on the one hand, it can prevent rainwater from flowing upward from the surface of the second laminate 121, thereby improving the waterproof performance of the photovoltaic tile assembly 1; on the other hand, the second waterproof component 15 can play a supporting role between the upper photovoltaic tile 12 and the flat tile 2 erected on the upper photovoltaic tile 12, thereby ensuring that the upper photovoltaic tile 12 stably supports the flat tile 2.

[0102] It is understandable that the second waterproof member 15 may also extend to cover the side surface of the third member 17 to improve the assembly stability of the second waterproof member 15 .

[0103] In one embodiment, as shown in FIG2 and FIG7 , the photovoltaic tile assembly 1 further includes a snap-fit ​​structure 18 . The upper photovoltaic tile 12 is mounted on the lower photovoltaic tile 11 , and the upper photovoltaic tile 12 and the lower photovoltaic tile 11 are connected via the snap-fit ​​structure 18 .

[0104] In one embodiment, the clamping structure 18 includes a fourth component 181 and a fifth component 182. The fourth component 181 includes a first assembly portion 1811 and a third clamping portion 1812 connected to the first assembly portion 1811, and the first assembly portion 1811 is used to assemble with the lower photovoltaic tile 11. The fifth component 182 includes a second assembly portion 1821 and a fourth clamping portion 1822 connected to the second assembly portion 1821, and the fourth clamping portion 1822 is clamped with the third clamping portion 1812, and the second assembly portion 1821 is used to assemble with the upper photovoltaic tile 12.

[0105] By setting the fourth component 181 and the fifth component 182, the first assembly portion 1811 of the fourth component 181 is assembled with the lower photovoltaic tile 11, the second assembly portion 1821 of the fifth component 182 is assembled with the upper photovoltaic tile 12, and the third clamping portion 1812 of the fourth component 181 is clamped with the fourth clamping portion 1822 of the fifth component 182. In this way, on the one hand, the structure of the clamping structure 18 is relatively simple. During assembly, only the third clamping portion 1812 and the fourth clamping portion 1822 need to be clamped to realize the assembly of the lower photovoltaic tile 11 and the upper photovoltaic tile 12, which is conducive to reducing the installation difficulty of the photovoltaic tile assembly 1; on the other hand, during assembly, the fourth component 181 can be assembled with the lower photovoltaic tile 11 and the fifth component 182 can be assembled with the upper photovoltaic tile 12 first, and then the third clamping portion 1812 of the fourth component 181 can be clamped with the fourth clamping portion 1822 of the fifth component 182 to complete the assembly. In this way, the length of the snap-in structure 18 (the dimension of the snap-in structure 18 perpendicular to the paper surface in Figure 7) can be made into a standard length, thereby realizing the standardization of the snap-in structure 18, and in the actual assembly process, the installation position of the snap-in structure 18 can be adjusted according to the actual assembly position of the photovoltaic tiles; on the other hand, when the lower photovoltaic tile 11 or the upper photovoltaic tile 12 needs to be replaced, the third snap-in part 1812 and the fourth snap-in part 1822 of the snap-in structure 18 can be opened, thereby facilitating the independent disassembly and assembly of the photovoltaic tiles.

[0106] In one embodiment, the clamping structure 18 further includes a second limiting member 183 , which is detachably disposed on one of the fourth component 181 and the fifth component 182 and limits the clamping portion of the other of the fourth component 181 and the fifth component 182 .

[0107] By setting the second limiting piece 183, the fourth component 181 or the fifth component 182 can be limited, so that the third clamping part 1812 and the fourth clamping part 1822 can be stably maintained in the clamping state, thereby improving the clamping stability of the third clamping part 1812 and the fourth clamping part 1822, thereby improving the assembly stability of the photovoltaic tile and improving the wind-resistant performance of the photovoltaic tile assembly 1.

[0108] It should be noted that, when limiting, the second limiting member 183 may abut against the limited clamping portion, or there may be a small gap between the second limiting member 183 and the limited clamping portion to prevent the limited clamping portion from loosening.

[0109] In one embodiment, the fifth component 182 further includes a third assembly portion 1823 connected to the second assembly portion 1821 , and the second limiting member 183 is detachably disposed on the third assembly portion 1823 to limit the third clamping portion 1812 .

[0110] In this way, when assembling the lower photovoltaic tile 11 and the upper photovoltaic tile 12, firstly, the third clamping part 1812 and the fourth clamping part 1822 are clamped, and then the second limiting member 183 is assembled on the third assembly part 1823, and the end of the second limiting member 183 is placed in a predetermined limiting position to achieve the purpose of limiting the third clamping part 1812.

[0111] In one embodiment, as shown in FIGS. 7 and 8 , the fifth member 182 further includes a second base portion 1824, the second base portion 1824 having a third end and a fourth end disposed oppositely along a first direction X, and a third side and a fourth side disposed oppositely along a second direction Y; the first direction X intersects with the second direction Y, and the first direction X is parallel to the extension direction of the second base portion 1824. Further, the fourth clamping portion 1822 is disposed at the third end, the second assembly portion 1821 and the third assembly portion 1823 are disposed at the fourth end; the fourth clamping portion 1822 and the third assembly portion 1823 are located on the third side, and the second assembly portion 1821 is located on the fourth side.

[0112] The above arrangement can reasonably arrange the positions of the second assembly part 1821, the third assembly part 1823 and the fourth clamping part 1822. It can be understood that the second laminate 121 of the upper photovoltaic tile 12 is located on the fourth side of the second base part 1824. By locating the fourth clamping part 1822 and the third assembly part 1823 on the third side, the second laminate 121 can be prevented from interfering with the assembly of the second stopper 183 during assembly, and the second laminate 121 can be prevented from interfering with the clamping of the fourth component 181 and the fifth component 182.

[0113] In one embodiment, a fourth clamping protrusion 18211 is disposed on the second assembly portion 1821 , and a fourth clamping groove 1231 is disposed on the second lower frame 123 . The fourth clamping protrusion 18211 is clamped in the fourth clamping groove 1231 .

[0114] In one embodiment, as shown in FIG. 8 , one of the third assembly portion 1823 and the second stopper 183 is provided with a fifth clamping protrusion 18232, and the other of the third assembly portion 1823 and the second stopper 183 is provided with a fifth clamping groove 1831, and the fifth clamping protrusion 18232 is clamped in the fifth clamping groove 1831. In this way, the second stopper 183 is clamped with the third assembly portion 1823, which can reduce the structural complexity of the second stopper 183 and the fifth member 182 on the one hand, and make the assembly of the second stopper 183 and the fifth member 182 more convenient on the other hand.

[0115] In a specific embodiment, as shown in FIG3 , the third assembly portion 1823 is provided with a fifth clamping protrusion 18232, and the second stopper 183 is provided with a fifth clamping groove 1831. The fifth clamping groove 1831 is a "large groove cavity and small groove opening" structure, and the fifth clamping protrusion 18232 is clamped in the groove cavity of the fifth clamping groove 1831.

[0116] It can be understood that, referring to FIG. 8 , the fifth engaging groove 1831 penetrates the second stopper 183 in a direction perpendicular to the paper surface, and during assembly, the fifth engaging protrusion 18232 is embedded in the fifth engaging groove 1831 in a direction perpendicular to the paper surface.

[0117] It should be noted that after the second limiting member 183 is assembled, the end of the second limiting member 183 close to the first connection portion may abut against the third clamping portion 1812 or have a small gap, thereby ensuring that the third clamping portion 1812 and the fourth clamping portion 1822 will not be disengaged.

[0118] In one embodiment, as shown in Figures 9 and 10, the third assembly portion 1823 is provided with a sixth assembly hole 18231, and the second stopper 183 is passed through the sixth assembly hole 18231 and threadedly connected to the sixth assembly hole 18231. Exemplarily, the second stopper 183 is a bolt or a screw.

[0119] In this way, on the one hand, the structural complexity of the second limit member 183 and the fifth component 182 can be reduced, and on the other hand, the second limit member 183 and the fifth component 182 can be assembled more conveniently; on still another hand, the locking degree of the third clamping portion 1812 and the fourth clamping portion 1822 can be adjusted by adjusting the screw-in depth of the second limit member 183, so that the operator can adjust the locking degree of the third clamping portion 1812 and the fourth clamping portion 1822 according to actual needs.

[0120] In one embodiment, as shown in Fig. 7, the second assembly portion 1821 and the second lower frame 123 may also be connected via a fifth fastener 165. In this way, the connection stability between the second assembly portion 1821 and the second lower frame 123 may be further improved.

[0121] In one embodiment, the third clamping portion 1812 is provided with a first clamping slot 18121, and the fourth clamping portion 1822 is provided with a second clamping slot 18221. The notch of the first clamping slot 18121 is oriented opposite to the notch of the second clamping slot 18221. Part of the first clamping slot 18121 extends into the second clamping slot 18221, and part of the second clamping slot 18221 extends into the first clamping slot 18121.

[0122] Thus, when the third clamping part 1812 and the fourth clamping part 1822 are clamped, the notch of the first clamping slot 18121 is oriented opposite to the notch of the second clamping slot 18221, and the third clamping part 1812 and the fourth clamping part 1822 move toward each other, so that part of the first clamping slot 18121 extends into the second clamping slot 18221, and part of the second clamping slot 18221 extends into the first clamping slot 18121, so that the clamping of the third clamping part 1812 and the fourth clamping part 1822 can be achieved, and the assembly process is relatively simple and easy to operate. Further, by making the second limiter 183 apply a force toward the fourth clamping part 1822 to the third clamping part 1812, the third clamping part 1812 and the fourth clamping part 1822 can be locked, and the locking process is relatively simple and easy to operate.

[0123] In one embodiment, the first assembly portion 1811 is provided with a second accommodating cavity 18111, and the second accommodating cavity 18111 is used to embed the first upper frame 113 of the lower photovoltaic tile 11. In this way, the assembly of the lower photovoltaic tile 11 and the first assembly portion 1811 can be made simpler, reducing the assembly difficulty.

[0124] In one embodiment, the fourth component 181 further includes a second fixing portion 1813 , which is used to fix the fourth component 181 ; one end of the second fixing portion 1813 is connected to the cavity opening of the second accommodating cavity 18111 , and the other end extends in a direction away from the second accommodating cavity 18111 .

[0125] In this way, by setting the second fixing portion 1813, it is convenient to fix the fourth component 181 on the installation base. Exemplarily, the second fixing portion 1813 can be fixed on the tile hanging bar 3. It should be noted that before assembling the lower photovoltaic tile 11, the fourth component 181 can be fixed on the tile hanging bar 3 by the second fixing portion 1813, and then the first upper frame 113 of the lower photovoltaic tile 11 is embedded in the second accommodating cavity 18111 to realize the assembly of the lower photovoltaic tile 11 and the fourth component 181.

[0126] In one embodiment, a second shrinkage surface 18131 is provided between the cavity wall of the second accommodating cavity 18111 and a side surface of the second fixing portion 1813 close to the second accommodating cavity 18111. Exemplarily, the second shrinkage surface 18131 may be a curved surface or a flat surface.

[0127] By setting the second necked surface 18131, on the one hand, a smooth transition can be achieved between the cavity wall of the second accommodating cavity 18111 and the side surface of the second fixing portion 1813 close to the second accommodating cavity 18111, thereby avoiding scratches on the lower photovoltaic tile 11 during assembly; on the other hand, the volume of the second accommodating cavity 18111 can be smoothly reduced from the inside to the outside, and after the first upper frame 113 is embedded in the second accommodating cavity 18111, the risk of the first upper frame 113 escaping from the second accommodating cavity 18111 can be reduced.

[0128] In one embodiment, a fifth assembly hole 18132 is provided on the second fixing portion 1813. The fifth member 182 can be fixed to the tile bar 3 by a fourth fastener 164. Specifically, the fourth fastener 164 can be inserted into the fifth assembly hole 18132 and connected to the tile bar 3.

[0129] In one embodiment, a second limiting protrusion 18134 is provided on a side surface of the second fixing portion 1813 away from the second accommodating cavity 18111. By providing the second limiting protrusion 18134, when the fifth member 182 is fixed, the second limiting protrusion 18134 can serve as a reference and positioning function, and by making the second limiting protrusion 18134 abut against the tile hanging strip 3, the second fixing portion 1813 can be quickly positioned, thereby improving assembly efficiency.

[0130] In one embodiment, the second fixing portion 1813 is provided with a fourth groove 18133. Exemplarily, the number of the fourth grooves 18133 can be multiple. In a specific embodiment, the fourth grooves 18133 can be evenly arranged on both sides of the fifth assembly hole 18132. By providing the fourth grooves 18133, on the one hand, it is helpful to save materials, and on the other hand, it is helpful to reduce the adverse effect of the unevenness of the surface of the tile hanging strip 3 on the assembly of the second fixing portion 1813.

That is, the overlapping structure between two adjacent middle photovoltaic tiles 13 is the same as the overlapping structure at the node B in FIG. 2, and the embodiment of the present application will not be repeated here.

[0133] In one embodiment, as shown in Figure 11, the middle photovoltaic tile 13 includes a third laminate 131 and a third upper frame 132 and a third lower frame 133 arranged on the third laminate 131, wherein a third shock-absorbing member 135 is arranged on the third upper frame 132, and a fourth waterproof member 134 is arranged on the third lower frame 133.

[0134] It can be understood that the structures of the upper photovoltaic tile 12, the lower photovoltaic tile 11 and the middle photovoltaic tile 13 can be the same.

[0135] Please refer to Figures 12 and 13. The installation method of the photovoltaic tile assembly 1 provided in the embodiment of the present application is as follows: first, the second component 142, the third component 17 and the fourth component 181 are respectively fixed on different tile hanging strips 3, wherein the second component 142 is located near the eaves, the third component 17 is located near the ridge, and the fourth component 181 is located between the eaves and the ridge, and then the photovoltaic tiles are installed in sequence from the eaves to the ridge.

[0136] Exemplarily, taking the middle photovoltaic tile 13 as an example, the third upper frame 132 of the middle photovoltaic tile 13 is inserted into the second receiving cavity 18111 of the fourth component 181 in the horizontal direction, and then the middle photovoltaic tile 13 is dropped, so that the fifth component 182 on the third lower frame 133 is engaged with the fourth component 181 on the tile hanging strip 3, and then the second limiter 183 is used to lock it. When disassembling, first open the second limiter 183, and then push the middle photovoltaic tile 13 upward to disengage the fourth component 181 from the fifth component 182, and then the middle photovoltaic tile 13 can be disassembled separately. The disassembly and assembly method of the upper photovoltaic tile 12 and the lower photovoltaic tile 11 is the same as that of the middle photovoltaic tile 13, and the embodiments of the present application will not be repeated here.

[0137] The photovoltaic tile assembly 1 provided in the embodiment of the present application not only has good reliability, but also can evenly transfer the force of the entire system to the installation foundation (such as the tile hanging strip 3), thereby ensuring that the photovoltaic tile assembly 1 has good wind resistance; on the other hand, it can be adapted to various types of flat tiles 2, and the length of the overlap connection structure can be adjusted according to actual conditions, which is conducive to installation and processing in non-standard positions; on another hand, it has a high degree of compatibility with the frame of the photovoltaic tile, which is conducive to standardization.

[0138] In a third aspect, an embodiment of the present application provides a rooftop photovoltaic system, comprising the photovoltaic tile assembly 1 in any embodiment of the second aspect.

[0139] The rooftop photovoltaic system provided in the embodiment of the present application, on the one hand, during assembly, only the first clamping portion 1412 and the second clamping portion 1422 need to be clamped to achieve the overlapping assembly of the lower photovoltaic tile 11 and the flat tile 2, which is beneficial to reducing the difficulty of installing the photovoltaic tile assembly 1; on the other hand, the first component 141 and the second component 142 can be assembled independently, and the lengths of the first component 141 and the second component 142 can be made into standard lengths, thereby achieving standardization of the first component 141 and the second component 142. Further, in the actual assembly process, the installation positions of the first component 141 and the second component 142 can be adjusted according to the actual assembly position of the lower photovoltaic tile 11; on the other hand, when the lower photovoltaic tile 11 needs to be replaced, the first clamping portion 1412 and the second clamping portion 1422 can be disengaged, thereby facilitating the independent disassembly and assembly of the photovoltaic tiles. By setting the first limiting piece 143, the first component 141 or the second component 142 can be limited, so that the first clamping portion 1412 and the second clamping portion 1422 can be stably maintained in a clamping state, thereby improving the clamping stability of the first clamping portion 1412 and the second clamping portion 1422, thereby improving the assembly stability of the lower photovoltaic tile 11 and improving the wind-resistant performance of the photovoltaic tile assembly 1.
