Description

Technical Field

[0001] The present application relates to the field of photovoltaic technology, and in particular to a roof tile, a roof tile assembly, and a photovoltaic assembly. Background Art

[0002] Photovoltaic panel technology integrates solar photovoltaic modules onto building roofs to generate solar power. Building rooftop space is often an underutilized resource, and rooftop photovoltaic panel technology allows photovoltaic modules to be installed on the roof, converting solar energy into electricity, enabling energy collection and utilization within the building.

[0003] In the related art, trapezoidal colored steel tiles are installed on the roof, and then photovoltaic panels are installed on the colored steel tiles, thereby integrating photovoltaic modules into the roof of the building. Specifically, the photovoltaic panels need to occupy a large space on the roof, and the colored steel tiles also need to ensure a large size space.

[0004] However, color steel tiles occupy a large space and need to be arranged in multiple pieces and fixedly connected. However, in the process of fixing the multiple color steel tiles, multiple connecting parts are required to achieve the connection between the multiple color steel tiles, which makes the installation of multiple color steel tiles more difficult.

[0053] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0054] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application.

[0055] It should be understood that when an element or layer is referred to as being "on, adjacent to, connected to, or coupled to" another element or layer, it can be directly on, adjacent to, connected to, or coupled to the other element or layer, or there can be intervening elements or layers. In contrast, when an element is referred to as being "directly on, directly adjacent to, directly connected to, or directly coupled to" another element or layer, there are no intervening elements or layers. It should be understood that although the terms first, second, third, etc. may be used to describe various elements, components, regions, layers, doping types, and / or portions, these elements, components, regions, layers, doping types, and / or portions should not be limited by these terms. These terms are merely used to distinguish one element, component, region, layer, doping type, or portion from another element, component, region, layer, doping type, or portion. Therefore, without departing from the teachings of the present application, the first element, component, region, layer, doping type, or portion discussed below may be represented as a second element, component, region, layer, or portion.

[0056] Spatially relative terms such as "under," "beneath," "beneath," "under," "above," "above," etc., may be used herein to describe the relationship of an element or feature shown in the figures to other elements or features. It should be understood that in addition to the orientations shown in the figures, spatially relative terms also include different orientations of the device in use and operation. For example, if the device in the drawings is turned over, the element or feature described as "under" or "beneath" or "beneath" the other elements will be oriented as "above" the other elements or features. Thus, the exemplary terms "under" and "under" can include both upper and lower orientations. In addition, the device can also include alternative orientations (e.g., rotated 90 degrees or other orientations), and the spatial descriptors used herein are interpreted accordingly.

[0057] As used herein, the singular forms "a," "an," and "the" may also include the plural forms, unless the context clearly indicates otherwise. It should also be understood that the terms "include," "comprising," "having," and the like specify the presence of stated features, integers, steps, operations, components, parts, or combinations thereof, but do not preclude the presence or addition of one or more other features, integers, steps, operations, components, parts, or combinations thereof. Also, in this specification, the term "and / or" includes any and all combinations of the relevant listed items.

[0058] Embodiments of the application are described herein with reference to cross-sectional views which are schematic illustrations of ideal embodiments (and intermediate structures) of the application, such that variations in the shapes shown due to, for example, manufacturing techniques and / or tolerances are anticipated. Accordingly, embodiments of the application should not be limited to the specific shapes of the regions shown herein, but rather include deviations in shapes due to, for example, manufacturing techniques. For example, an implanted region shown as a rectangle typically has rounded or curved features and / or an implant concentration gradient at its edges, rather than a binary change from an implanted region to a non-implanted region. Similarly, a buried region formed by implantation may result in some implantation in the region between the buried region and the sidewalls through which the implantation occurs. Accordingly, the regions shown in the figures are schematic in nature, their shapes do not represent the actual shape of the regions of the device, and do not limit the scope of the application.

[0059] It should be noted that in order to integrate photovoltaic modules into the roof of a building to achieve solar power generation, it is necessary to pre-install roof tiles on the roof, connect the roof tiles to the roof, and then fix the photovoltaic modules on the roof tiles, so as to realize the installation of the photovoltaic modules on the roof.

[0060] Specifically, in the process of fixing the roof tiles to the roof, in order to increase the photoelectric conversion rate of the photovoltaic modules, the photovoltaic modules occupy a larger area. It is understandable that the roof tiles also need to occupy a larger area. However, since the roof tiles also need to occupy a larger area, if larger roof tiles are directly selected for installation and fixation to the roof, it will inevitably lead to greater difficulty in manufacturing the roof tiles and greater difficulty in installing the roof tiles to the roof.

[0061] First, refer to Figure 1 and Figure 2 As shown, the embodiment of the present application provides a roof tile 10 for connecting with a roof and a photovoltaic module 30. The roof tile 10 includes a first clamping portion 11, a connecting portion 12 and a second clamping portion 13. Figure 3 As shown, the first clamping portion 11 includes a first bending section 111, and the first bending section 111 is bent to form a first protrusion 1111; the connecting portion 12 is connected to one end of the first clamping portion 11. Figure 4 As shown, the second clamping portion 13 is connected to one end of the connecting portion 12 away from the first clamping portion 11, and is bent to form a first opening cavity 131; wherein, the protruding direction of the first protrusion 1111 is toward the second clamping portion 13; during installation, multiple roofing tiles 10 are overlapped in sequence; among two adjacent roofing tiles 10, the first clamping portion 11 of one roofing tile 10 is used to be arranged in the first opening cavity 131 of the other roofing tile 10, and the first protrusion 1111 of the first clamping portion 11 is used to clamp with the second clamping portion 13 of the other roofing tile 10.

[0062] Specifically, the present invention provides a plurality of roofing tiles 10, which are sequentially overlapped to form a unified whole. The overlapping connection of the multiple roofing tiles 10 in the present invention ensures that each roofing tile 10 is relatively small, facilitating the manufacturing process of the roofing tiles 10. Furthermore, the overlapping connection of the multiple roofing tiles 10 allows them to be installed and secured to different locations on the roof, reducing the difficulty of installing the roofing tiles 10 on the roof.

[0063] Furthermore, in the process of installing multiple roofing tiles 10, it is only necessary to clamp the first protrusion 1111 of the first clamping portion 11 of one roofing tile 10 with the second clamping portion 13 of another roofing tile 10, so that the two roofing tiles 10 can be fixedly connected. In the process of installing multiple roofing tiles 10, there is no need to damage the surface structure of the roofing tiles 10 through welding, bolts and other connection methods. On the one hand, the reliability of the roofing tiles 10 can be improved; on the other hand, the aesthetics of the roofing tiles 10 can be improved.

[0064] In one embodiment, referring to Figure 3 As shown, the first engaging portion 11 further includes an extension section 112 . The extension section 112 connects the first bending section 111 away from the connecting portion 12 ; the extension section 112 extends along a first direction that is inclined to the protruding direction of the first protrusion 1111 and faces the second engaging portion 13 .

[0065] It should be noted that the first direction is Figure 1 The X direction in .

[0066] In this way, after the installation and fixation between multiple roof tiles 10 are completed, when the roof tiles 10 are connected to the roof and the photovoltaic components 30, when affected by rainwater, since the first direction is inclined to the protruding direction of the first protrusion 1111, and the first direction is toward the second clamping portion 13, rainwater will only accumulate between the extension section 112 and the first protrusion 1111, and the extension section 112 can prevent rainwater from reaching the roof from the first bending section 111 away from the direction of the second clamping portion 13, and then the extension section 112 can play a waterproof role, which can avoid the problem of water leakage in the roof tiles 10.

[0067] In one embodiment, referring to Figure 3 As shown, the first clamping portion 11 further includes a support segment 113. The support segment 113 is connected to the side of the extension segment 112 away from the first bending segment 111 and is located on the side of the extension segment 112 away from the second clamping portion 13; the support segment 113 extends along a second direction, which is inclined to the first direction.

[0068] It should be noted that the second direction is Figure 1 in the Y direction.

[0069] In this way, since the support section 113 extends along the second direction, the second direction is inclined to the first direction, so that the support section 113 can provide a reverse force for the extension section 112. For example, when affected by rainwater, rainwater will accumulate between the extension section 112 and the first protrusion 1111. It can be understood that the accumulation of rainwater there will generate a force on the extension section 112 that is inclined to the first direction. When the extension section 112 is under the action of this force for a long time, the extension section 112 will bend and deform in this direction, and eventually the extension section 112 will not be able to function normally with waterproofing. Furthermore, since the support section 113 is connected to the side of the extension section 112 away from the first bending section 111, and is located on the side of the extension section 112 away from the second clamping portion 13; the support section 113 extends along the second direction, and the second direction is inclined to the first direction, so that when rainwater accumulates between the extension section 112 and the first protrusion 1111, the support section 113 can generate a reverse force in the direction in which the rainwater presses the extension section 112, thereby reducing the force of the rainwater on the extension section 112 in this direction, so that the extension section 112 can be supported by the support section 113, thereby improving the stability and reliability of the overlap of the roof tiles 10.

[0070] In one embodiment, the angle between the first direction and the second direction is 30°-120°.

[0071] It should be noted that, when affected by rainwater, rainwater will accumulate between the extension section 112 and the first protrusion 1111. It can be understood that the rainwater will generate pressure on the extension section 112 at this location, acting on the surface of the extension section 112. Although the force is inclined in various directions to the surface of the extension section 112, the main force direction of the pressure is perpendicular to the surface of the extension section 112. Furthermore, it can be understood that when the angle between the first direction and the second direction is 90°, the vertical direction can be used to generate a reverse force to the main force direction of the rainwater pressing on the extension section 112, thereby reducing the force of the rainwater on the extension section 112 in the main force direction.

[0072] At the same time, based on the above description, it can be seen that the force exerted by rainwater on the extension section 112 is inclined in various directions to the surface of the extension section 112. By setting the angle between the first direction and the second direction to 30°-120°, the first direction and the second direction can be inclined to decompose it into the vertical force and the inclined force exerted by rainwater on the extension section 112, thereby resisting the force exerted by rainwater on the extension section 112 in various directions, thereby further improving the stability and reliability of the overlap of the roof tiles 10.

[0073] In this way, within this angle range, the supporting section 113 can provide sufficient supporting force for the extending section 112 , thereby improving the supporting effect of the supporting section 113 supporting the extending section 112 .

[0074] In one embodiment, referring to Figure 4 As shown, the second engaging portion 13 includes a second bent section 132. The second bent section 132 includes a first sub-bent section 1321 and a second sub-bent section 1322 connected to each other. The first sub-bent section 1321 forms a first sub-protrusion 1323, which protrudes toward the first engaging portion 11 and is used to engage with a portion of the first engaging portion 11 of an adjacent roofing tile 10. The second sub-bent section 1322 forms a second sub-protrusion 1324, which protrudes in a direction opposite to that of the first sub-protrusion 1323 and is used to engage with at least a portion of the remaining first engaging portion 11 of the adjacent roofing tile 10.

[0075] In this way, the first sub-protrusion 1323 can be clamped with part of the first clamping portion 11 of the adjacent roof tile 10, and the second sub-protrusion 1324 can be clamped with at least part of the remaining first clamping portion 11 of the adjacent roof tile 10. Since the protruding direction of the second sub-protrusion 1324 is opposite to the protruding direction of the first sub-protrusion 1323, the clamping connection between the second clamping portion 13 and the first clamping portion 11 can be achieved by forces in two opposite directions, thereby improving the clamping stability of the first clamping portion 11 and the second clamping portion 13, and further improving the tightness of the overlap connection between multiple roof tiles 10.

[0076] It should be noted that the second sub-protrusion 1324 engages with at least a portion of the remaining first engaging portion 11 of the adjacent roofing tile 10. Specifically, the second sub-protrusion 1324 engages with the remaining first engaging portion 11 of the adjacent roofing tile 10, or the second sub-protrusion 1324 engages with all of the remaining first engaging portions 11 of the adjacent roofing tile 10. It is understood that if the second sub-protrusion 1324 engages with the remaining first engaging portion 11 of the adjacent roofing tile 10, the manufacturing cost of the second sub-protrusion 1324 can be reduced, thereby reducing overall production costs. If the second sub-protrusion 1324 engages with all of the remaining first engaging portions 11 of the adjacent roofing tile 10, the engagement strength between the second sub-protrusion 1324 and the first engaging portions 11 can be further enhanced, thereby improving the tightness of the overlapping connection between the multiple roofing tiles 10.

[0077] In one embodiment, referring to Figure 1As shown, part of the side wall of the first clamping portion 11 , the connecting portion 12 and part of the side wall of the second clamping portion 13 enclose a second opening cavity 14 , and the opening direction of the second opening cavity 14 is opposite to that of the first opening cavity 131 .

[0078] It should be noted that when multiple roof tiles 10 are overlapped and fixed to each other, it is necessary to ensure that the opening direction of the first opening cavity 131 is towards the gravity direction of the roof tile 10, so that when the roof tile 10 is installed and fixed to the roof, the connection structure between the roof tile 10 and the roof can be arranged in the first opening cavity 131, thereby further improving the aesthetics of the connection between the roof tile 10 and the roof.

[0079] Furthermore, since the opening direction of the second opening cavity 14 is opposite to the opening direction of the first opening cavity 131, that is, the opening direction of the second opening cavity 14 is toward the direction of gravity away from the roof tile 10, when it is rainy outside, rainwater will be discharged to the outside of the roof tile 10 through the second opening cavity 14, thereby improving the drainage performance of the roof tile 10.

[0080] In one embodiment, the roof tile 10 is an integrally formed structure.

[0081] In this way, there is no need to assemble and connect multiple parts. On the one hand, the manufacturing difficulty of the roof tile 10 can be reduced; on the other hand, the overall stability of the roof tile 10 can be improved.

[0082] In the second aspect, the embodiment of the present application provides a roof tile assembly 20, referring to Figure 5 and Figure 6 As shown, the roof tile assembly 20 includes at least two roof tiles 10 and a fixing member 21. The at least two roof tiles 10 are overlapped and arranged in sequence along the third direction. The roofing tile 10 includes a first clamping portion 11, a connecting portion 12 and a second clamping portion 13, which are connected in sequence along a third direction; the second clamping portion 13 is bent to form a first opening cavity 131, and the opening direction of the first opening cavity 131 is toward the gravity direction of the roofing tile 10; in two adjacent roofing tiles 10, the first clamping portion 11 of one roofing tile 10 is arranged in the first opening cavity 131 of the other roofing tile 10; the fixing member 21 is arranged in the first opening cavity 131, and the fixing member 21 includes a third clamping portion 211 and a fixing portion 212 that are connected to each other; the third clamping portion 211 is arranged between the first clamping portion 11 of one roofing tile 10 and the second clamping portion 13 of the adjacent roofing tile 10, and the first clamping portion 11, the third clamping portion 211 and the second clamping portion 13 are clamped together; the fixing portion 212 is used to be fixedly connected to an external support structure.

[0083] It should be noted that the third party Figure 1The support structure is the structure to which the roofing tile 10 is attached and fixed. In the above embodiments of this application, the roof is used as the supporting structure for illustrative purposes. Of course, the support structure is not limited to the roof; any location or structure requiring the roofing tile 10 to be fixed and installed can be considered the support structure described in this application. Similarly, in the following embodiments of this application, the roof is used as an example to represent the supporting structure. The support structure will not be further described here.

[0084] Specifically, during the installation of the roof tile assembly 20, it is only necessary to connect the first clamping portion 11 of one roof tile 10 with the second clamping portion 13 of another roof tile 10, so that the two roof tiles 10 can be fixedly connected. During the installation of multiple roof tiles 10, there is no need to damage the surface structure of the roof tiles 10 through welding, bolts and other connection methods. On the one hand, the reliability of the roof tile assembly 20 can be improved; on the other hand, the aesthetics of the roof tile assembly 20 can be improved.

[0085] Furthermore, the third clamping portion 211 is provided between the first clamping portion 11 of one roofing tile 10 and the second clamping portion 13 of the adjacent roofing tile 10, and the first clamping portion 11, the third clamping portion 211, and the second clamping portion 13 are clamped together; the fixing portion 212 is used for fixed connection with an external support structure. It is understood that the fixing member 21 can be used to achieve a fixed connection between the roofing tile 10 and the roof, thereby facilitating the installation of the roofing tile assembly 20 and the roof, and reducing the difficulty of installing the roofing tile assembly 20 and the roof. At the same time, the first clamping portion 11 of one roofing tile 10 and the second clamping portion 13 of the adjacent roofing tile 10 can be further clamped together by the third clamping portion 211, thereby further improving the connection tightness of the roofing tile assembly 20.

[0086] In addition, since the opening direction of the first opening cavity 131 is toward the direction of gravity of the roof tile 10, and the fixing member 21 is arranged in the first opening cavity 131, after the fixing member 21 is connected to the roof tile 10, the fixing member 21 is always in the enclosed space surrounded by the first opening cavity 131. Therefore, under the action of rainwater, the roof tile 10 can block rainwater from entering the first opening cavity 131, thereby preventing rainwater from contacting the fixing member 21, thereby preventing the roof tile assembly 20 from leaking.

[0087] In one embodiment, the first clamping portion 11 includes a first bending section 111 and an extension section 112, the first bending section 111 connects the connecting portion 12 and the extension section 112, the first bending section 111 is bent to form a first protrusion 1111, the protruding direction of the first protrusion 1111 is toward the second clamping portion 13, and the first protrusion 1111 is clamped to the third clamping portion 211; the extension section 112 extends along a first direction, the first direction is inclined to the protruding direction of the first protrusion 1111, and the first direction is toward the second clamping portion 13.

[0088] In this way, during the installation of the roof tile assembly 20, it is only necessary to engage the first protrusion 1111 of the first engaging portion 11 of one roof tile 10 with the second engaging portion 13 of the other roof tile 10, thereby achieving a fixed connection between the two roof tiles 10. The reliability of the fixed connection of the roof tile assembly 20 can be further improved by engaging the first protrusion 1111 with the second engaging portion 13 of the other roof tile 10.

[0089] In addition, when affected by rainwater, since the first direction is inclined to the protruding direction of the first protrusion 1111 and the first direction is toward the second clamping portion 13, rainwater will only accumulate between the extension section 112 and the first protrusion 1111. The extension section 112 can prevent rainwater from reaching the roof from the direction of the first bending section 111 away from the second clamping portion 13, and the extension section 112 can play a waterproof role, thereby avoiding the problem of water leakage in the roof tile 10.

[0090] In one embodiment, the first engaging portion 11 further includes a supporting section 113. The supporting section 113 is connected to a side of the extending section 112 away from the first bending section 111 and is located on a side of the extending section 112 away from the second engaging portion 13. The supporting section 113 extends along a second direction that is inclined relative to the first direction.

[0091] In this way, since the support section 113 extends along the second direction, the second direction is inclined to the first direction, so that the support section 113 can provide a reverse force for the extension section 112. For example, when affected by rainwater, rainwater will accumulate between the extension section 112 and the first protrusion 1111. It can be understood that the accumulation of rainwater there will generate a force on the extension section 112 that is inclined to the first direction. When the extension section 112 is under the action of this force for a long time, the extension section 112 will bend and deform in this direction, and eventually the extension section 112 will not be able to function normally with waterproofing. Furthermore, since the support section 113 is connected to the side of the extension section 112 away from the first bending section 111, and is located on the side of the extension section 112 away from the second clamping portion 13; the support section 113 extends along the second direction, and the second direction is inclined to the first direction, so that when rainwater accumulates between the extension section 112 and the first protrusion 1111, the support section 113 can generate a reverse force in the direction in which the rainwater presses the extension section 112, thereby reducing the force of the rainwater on the extension section 112 in this direction, so that the extension section 112 can be supported by the support section 113, thereby improving the stability and reliability of the overlap of the roof tiles 10.

[0092] In one embodiment, the second engaging portion 13 includes a second bent section 132. The second bent section 132 includes a first sub-bent section 1321 and a second sub-bent section 1322 connected to each other. The first sub-bent section 1321 forms a first sub-protrusion 1323, which is oriented toward the first engaging portion 11 and is engaged between the connecting portion 12 and a portion of the third engaging portion 211. The second sub-bent section 1322 forms a second sub-protrusion 1324, which is engaged with at least a portion of the remaining third engaging portion 211.

[0093] In this way, the first sub-protrusion 1323 can be clamped with part of the first clamping portion 11 of the adjacent roof tile 10, and the second sub-protrusion 1324 can be clamped with at least part of the remaining first clamping portion 11 of the adjacent roof tile 10. Since the protruding direction of the second sub-protrusion 1324 is opposite to the protruding direction of the first sub-protrusion 1323, the clamping connection between the second clamping portion 13 and the first clamping portion 11 can be achieved by forces in two opposite directions, thereby improving the clamping stability of the first clamping portion 11 and the second clamping portion 13, and further improving the tightness of the overlap connection between multiple roof tiles 10.

[0094] In one embodiment, referring to Figure 7As shown, the third clamping portion 211 includes a third clamping section 2111 and a connecting section 2112, the connecting section 2112 connects the third clamping section 2111 and the fixing portion 212, the third clamping section 2111 is bent to form a second protrusion 2113, the second protrusion 2113 is arranged between the first clamping portion 11 and the second clamping portion 13, and the second protrusion 2113 is clamped with the first clamping portion 11 and the second clamping portion 13.

[0095] Thus, on the one hand, the engagement of the second protrusion 2113 with the first and second engaging portions 11, 13 can further improve the tightness of the connection between the fixing member 21 and the roofing tile 10. On the other hand, the third engaging section 2111 and the connecting section 2112 can change the position of the fixing member 21 relative to the first and second engaging portions 11, 13, thereby avoiding interference during the connection between the fixing member 21, the first and second engaging portions 11, 13, and facilitating the connection between the fixing member 21, the first and second engaging portions 11, 13.

[0096] It should be noted that, during the process of the second protrusion 2113 being engaged with the first engaging portion 11 and the second engaging portion 13, the connecting section 2112 may or may not be in contact with the extension section 112, and the relative position between the connecting section 2112 and the extension section 112 may be designed according to actual needs. Here, the position between the connecting section 2112 and the extension section 112 will not be elaborated.

[0097] In one embodiment, referring to Figure 6 As shown, the roof tile assembly 20 further includes an adhesive member 22 , which is disposed on a side of the second clamping portion 13 away from the opening direction of the first opening cavity 131 and is used to connect the photovoltaic panel 31 .

[0098] In this way, the roof tile assembly 20 and the photovoltaic panel 31 can be connected by the adhesive 22. On the one hand, the adhesive connection method using the adhesive 22 can reduce the difficulty of installing and connecting the roof tile assembly 20 and the photovoltaic panel 31, which can facilitate installation by operators. On the other hand, the adhesive connection method using the adhesive 22 does not require welding, bolting, etc., which can avoid damage to the photovoltaic panel 31 caused by welding, bolting, etc., thereby increasing the service life of the photovoltaic panel 31.

[0099] In one embodiment, a portion of the sidewall of the first clamping portion 11 , the connecting portion 12 , and a portion of the sidewall of the second clamping portion 13 enclose a second opening cavity 14 . The opening direction of the second opening cavity 14 is opposite to that of the first opening cavity 131 .

[0100] In this way, since the opening direction of the second opening cavity 14 is opposite to the opening direction of the first opening cavity 131, that is, the opening direction of the second opening cavity 14 is toward the direction of gravity away from the roof tile 10, when it is rainy outside, rainwater will be discharged to the outside of the roof tile 10 through the second opening cavity 14, thereby improving the drainage performance of the roof tile 10.

[0101] In one embodiment, the roof tile 10 is an integrally formed structure.

[0102] In this way, there is no need to assemble and connect multiple parts. On the one hand, the manufacturing difficulty of the roof tile 10 can be reduced; on the other hand, the overall stability of the roof tile 10 can be improved, thereby improving the reliability of the roof tile assembly 20.

[0103] In a third aspect, the present application embodiment provides a photovoltaic assembly 30, referring to Figure 2 As shown, the photovoltaic assembly 30 includes a photovoltaic panel 31 and the roof tile 10 in the first aspect, and the photovoltaic panel 31 is connected to the roof tile 10; or, the photovoltaic assembly 30 includes a photovoltaic panel 31 and the roof tile assembly 20 in the second aspect, and the photovoltaic panel 31 is connected to the roof tile assembly 20.

[0104] In this way, the photovoltaic panel 31 and the roof can be fixedly connected through multiple roof tiles 10, which can reduce the difficulty of installing the roof tiles 10 and the roof. At the same time, during the installation of multiple roof tiles 10, there is no need to damage the surface structure of the roof tiles 10 through connection methods such as welding and bolts. On the one hand, it can improve the reliability of the roof tiles 10, and on the other hand, it can improve the aesthetics of the roof tiles 10.

[0105] In addition, since the opening direction of the first opening cavity 131 is toward the direction of gravity of the roof tile 10, and the fixing member 21 is arranged in the first opening cavity 131, after the fixing member 21 is connected to the roof tile 10, the fixing member 21 is always in the enclosed space surrounded by the first opening cavity 131. Therefore, under the action of rainwater, the roof tile 10 can block rainwater from entering the first opening cavity 131, thereby preventing rainwater from contacting the fixing member 21, thereby preventing the roof tile assembly 20 from leaking.

[0106] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are 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.

[0107] The above embodiments merely illustrate several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
