Description

Technical Field

[0001] This application relates to the field of building-integrated photovoltaics (BIPV) technology, and in particular to a tile installation structure and a photovoltaic system. Background Technology

[0002] A building needs to be well protected throughout its entire lifespan, and roof tiles are its crucial protective covering. During the construction process, it is essential to choose suitable roof tile materials that are not only durable but also waterproof, heat-insulating, environmentally friendly, and aesthetically pleasing.

[0003] With the development of technology, photovoltaic tiles are becoming increasingly popular. Photovoltaic tiles are energy-saving and environmentally friendly, suitable for roofing in various locations, widely used, have good load-bearing capacity, and can also generate electricity and store it for backup. They represent the future development trend. Currently, most civilian photovoltaic systems are wall-mounted systems or use rail brackets for connection.

[0004] However, the inventors believe that the aforementioned technologies have the following drawbacks: common mounting systems are glued to the back of the photovoltaic module through mounting brackets, resulting in poor structural stability and low installation efficiency; or photovoltaic modules with special integrated steel plates use steel plates instead of photovoltaic module backsheets, which is costly and not conducive to maintenance and replacement. Summary of the Invention

[0005] This application provides a tile installation structure and a photovoltaic system in one or more embodiments to solve or at least partially alleviate the problems of low structural strength, complicated installation, and high construction difficulty in related technologies.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0032] In the description of this application, it should be understood that the terms "center", "lateral", "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0033] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components.

[0034] In this application, the term "implementation" means that a specific feature, structure, or characteristic described in connection with an implementation can be included in at least one implementation of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same implementation, nor is it a separate or alternative implementation mutually exclusive with other implementations. Those skilled in the art will understand, explicitly and implicitly, that the implementations described in this application can be combined with other implementations.

[0035] As mentioned above, it should be emphasized that when the term "comprising / including" is used in this specification, it is used to explicitly indicate the presence of the stated feature, integer, step, or component, but does not exclude the presence or addition of one or more other features, integers, steps, components, or groups of features, integers, steps, or components. As used in this application, the singular forms "a," "an," and "the" also include the plural forms, unless the context clearly indicates otherwise.

[0036] One or more embodiments of this application disclose a tile mounting structure, with reference to... Figures 1 to 8 It includes a first connecting component 1, which is adapted to run along a first direction (refer to...). Figure 7The first connecting component 1 connects adjacent tiles 3 in the x-direction. The first connecting component 1 includes a first frame 11, a second frame 12, and a connecting body 13. The first frame 11 and the second frame 12 are adapted to connect one of the adjacent tiles 3 respectively. A first connecting port 131 is provided on one side of the connecting body 13. The first connecting port 131 is adapted to accommodate and fix the first frame 11 entering from that side. Above the first connecting port 131, the end of the connecting body 13 away from the first frame 11 extends and forms a second connecting port 132. A connecting structure is provided on the second frame 12. The second connecting port 132 is adapted to engage with the connecting structure, so that the tile 3 connected to the second frame 12 can overlap and be placed on the tile 3 connected to the first frame 11, thereby effectively preventing rainwater backflow. By integrating the connecting structure on the second frame 12, the number of parts in the system can be reduced, the installation operation can be simplified, the cost can be reduced, the installation efficiency can be improved, and the system stability can be improved.

[0037] This application solves the problem of photovoltaic tiles 5 falling off when the roof is subjected to reverse wind suction by using the upper and lower limit system of the first connection port 131 and the second connection port 132, ensuring the firmness and safety of the roof system. The mechanical fixing eliminates or reduces the need for adhesive bonding, solving the problems of weak adhesive bonding, failure, and insufficient connection strength, thus ensuring the firmness and safety of the system. Furthermore, by using the upper and lower hanging method and only adding aluminum alloy connectors, it solves the problems of complicated roof installation, high construction difficulty, and high installation accuracy, reducing costs and construction difficulty. By using a structure and shape similar to cement tiles, it solves the problems of incompatibility between photovoltaic systems and traditional roof shapes and abrupt architectural effects, achieving a perfect integration of photovoltaic buildings.

[0038] In some embodiments, the first frame 11, the second frame 12, and the connector 13 are made of aluminum alloy, which is lightweight while having higher structural strength and is not easily deformed or damaged.

[0039] In some embodiments, the connecting structure is formed along the length of the second frame 12, which can eliminate the installation positioning requirements of the connecting structure and further reduce the installation positioning requirements of the connector 13, effectively reducing the difficulty of the connection between the connector 13 and the connecting structure of the second frame 12.

[0040] like Figures 1 to 3In the embodiment shown, the first connection port 131 is provided with a first hook portion 1311 and a second hook portion 1312 with opposite openings on both sides. The connection structure includes a third hook portion 121 and a fourth hook portion 122 with opposite openings. The first hook portion 1311 is adapted to engage with the third hook portion 121, and the second hook portion 1312 is adapted to engage with the fourth hook portion 122. The first hook portion 1311, the second hook portion 1312, the third hook portion 121 and the fourth hook portion 122 are mechanically fastened by tenon and mortise, which can improve the connection strength and connection stability.

[0041] like Figure 2 In the illustrated embodiment, the third hook portion 121 is close to the bottom of the second frame 12, and the fourth hook portion 122 is away from the bottom of the second frame 12. The third hook portion 121 is a circular semi-open shape, which can rotate and engage with the first hook portion 1311. The fourth hook portion 122 can engage with the second hook portion 1312 as the third hook portion 121 and the first hook portion 1311 rotate. It can be understood that this design allows the second hook portion 1312 and the fourth hook portion 122 to engage through leverage. Applying a small force to the frame can trigger deformation and engagement. At the same time, this leverage is triggered by downward pressure, which is more in line with the installation and laying process of the tile 3, reduces additional operations, and improves installation efficiency.

[0042] In some embodiments, the elastic deformation capacity of the fourth hook portion 122 is greater than that of the third hook portion 121, which makes the engagement of the second hook portion 1312 and the fourth hook portion 122 smoother, and at the same time reduces the probability of the second hook portion 1312 and the fourth hook portion 122 breaking or being damaged.

[0043] like Figure 4 In the embodiment shown, the second hook portion 1312 is provided with a first rack portion 1313, and the fourth hook portion 122 is provided with a second rack portion 123. When the second hook portion 1312 and the fourth hook portion 122 are engaged, the first rack portion 1313 and the second rack portion 123 are adapted to mesh with each other to improve the engagement stability between the second hook portion 1312 and the fourth hook portion 122 and reduce the probability of the second hook portion 1312 and the fourth hook portion 122 disengaging.

[0044] In some embodiments, the second rack portion 123 is located at the root of the fourth hook portion 122, so that when the second hook portion 1312 and the fourth hook portion 122 are engaged, the first rack portion 1313 and the second rack portion 123 are engaged with each other, thereby reducing interference with the engagement process of the second hook portion 1312 and the fourth hook portion 122.

[0045] like Figures 1 to 3In the embodiment shown, the second hook portion 1312 is provided with a reinforcing rib 1314 on the opposite side of the fourth hook portion 122 to improve the structural strength and stability of the second hook portion 1312, reduce the probability of damage during the deformation and engagement of the second hook portion 1312, and at the same time obtain a higher restraining effect on the fourth hook portion 122.

[0046] like Figures 1 to 3 In the embodiment shown, a buffer 124 is provided at the bottom of the second frame 12. The buffer 124 is adapted to restrict the second frame 12 from contacting the tile 3 connected to the first frame 11, thereby buffering the second frame 12 and the tile 3 connected to the first frame 11 and reducing the probability of hard contact between the two.

[0047] In some embodiments, the buffer 124 is made of rubber and has elastic deformation capability, which can play a sealing role between the second frame 12 and the tile 3 connected to the first frame 11.

[0048] like Figure 2 In the embodiment shown, the bottom of the buffer 124 is provided with an arc-shaped portion 1241. The arc-shaped portion 1241 is adapted to guide the second frame 12 to rotate relative to the tile 3 connected to the first frame 11. It can be understood that the second frame 12 can be rotated through the arc-shaped portion 1241 at the bottom of the buffer 124, so that the first hook portion 1311 and the third hook portion 121 are pre-fitted, and then the rotation continues. Through the lever action, the second hook portion 1312 and the fourth hook portion 122 approach each other until they are engaged. This can effectively reduce the installation difficulty and improve the installation efficiency and installation stability.

[0049] like Figures 1 to 2 In the embodiment shown, the connector 13 is provided with a fifth hook portion 133, and the first frame 11 is provided with a sixth hook portion 111. The sixth hook portion 111 is adapted to engage with the fifth hook portion 133 to restrict the connector 13 from detaching from the first frame 11. By combining the sixth hook portion 111 on the first frame 11 and the fifth hook portion 133 on the connector 13, the connection stability of the two is improved and the probability of separation is reduced.

[0050] At this time, a first connection port 131 can be formed above the fifth hook part 133. The first frame 11 is located in the first connection port 131 through the overlapping cooperation between the sixth hook part 111 and the fifth hook part 133.

[0051] like Figures 1 to 2In the embodiment shown, the first frame 11 is provided with an installation part 112, which is adapted to be fixed to the batten 4. By directly installing and fixing the first frame 11 to the batten 4, the phenomenon of tile 3 falling off when the connector 13 is separated from the first frame 11 or fails can be reduced. The first frame 11 can help the tile 3 connected to it to be stable on the roof, realize the built-in anti-fall measures, and further enhance the safety of the system.

[0052] like Figures 1 to 2 In the embodiment shown, the mounting part 112 and the sixth hook part 111 cooperate to restrict the fifth hook part 133 from disengaging from the sixth hook part 111. By reinforcing the fifth hook part 133 through the mounting part 112 and the sixth hook part 111, the connection stability between the connector 13 and the first frame 11 is improved, and the probability of the connector 13 disengaging from the first frame 11 is reduced.

[0053] In some embodiments, the sixth hook portion 111 is formed along the length direction of the first frame 11, which can eliminate the installation positioning requirements of the sixth hook portion 111, further reducing the installation positioning requirements of the connector 13, and effectively reducing the difficulty of the connection and docking of the connector 13 and the sixth hook portion 111 of the first frame 11.

[0054] like Figure 3 In the illustrated embodiment, the connector 13 is provided with a support portion 113 and a mounting portion 112. A first connection port 131 can be formed between the upper part of the support portion 113 and the second connection port 132. The first frame 11 is adapted to be placed in the first connection port 131 above the support portion 113 and rest on the support portion 113. It can be understood that at this time, the second frame 12 is located above the tile 3 connected to the first frame 11. If a buffer 124 is provided on the second frame 12, the buffer 124 can contact the upper surface of the tile 3 connected to the first frame 11. The support portion 113 and the mounting portion 112 are adapted to fit onto different sides of the tile strip 4, and can form support in multiple directions, thereby improving the connection stability between the connector 13 and the tile strip 4. The mounting portion 112 is adapted to be fixedly connected to the tile strip 4.

[0055] In some embodiments, the mounting part 112 is fixed to the batten strip 4 by screws.

[0056] like Figures 5 to 7 In the illustrated embodiment, the tile mounting structure further includes a second connecting component 2, which is adapted to run along a second direction (refer to...). Figure 7The second connecting component 2 connects adjacent tiles 3 in the y-direction. The second connecting component 2 includes a third frame 21 and a fourth frame 22. The third frame 21 and the fourth frame 22 are adapted to connect one of the adjacent tiles 3 respectively. A cover plate portion 211 is provided on the outer side of the third frame 21, and a water trough portion 221 is provided on the outer side of the fourth frame 22. Multiple drainage grooves 2211 are provided on the water trough portion 2211. The cover plate portion 211 is adapted to overlap the drainage groove 2211 near the fourth frame 22. The multi-water trough design further enhances the waterproof performance of the overlapping position.

[0057] Meanwhile, the shapes of the third frame 21 and the fourth frame 22 are adapted to the left and right grooves of common cement tiles and ceramic tiles on the market, enabling seamless integration with traditional buildings.

[0058] In some embodiments, the number of drainage channels 2211 is two, which meets the requirements of lightweight, low cost and high waterproofing.

[0059] like Figures 5 to 7 In the embodiment shown, a first reinforcing part 2111 is provided on the cover plate part 211, and a second reinforcing part 2212 is provided on the water tank part 221. The first reinforcing part 2111 and the second reinforcing part 2212 are arranged in the overlapping direction of the cover plate part 211 and the water tank part 221 to enhance the structural strength of the cover plate part 211 and the water tank part 221 and reduce the probability of deformation.

[0060] In some embodiments, the first reinforcing part 2111 and the second reinforcing part 2212 are hollow structures, which can increase the hardness and structural strength of the overlapping position, and meet the requirements of lightweight, low cost and structural reinforcement.

[0061] like Figures 5 to 7 In the embodiment shown, the width of the drainage groove 2211 near the fourth frame 22 is smaller than the width of the other drainage grooves 2211, which can reduce the activity space of the cover plate portion 211 when it overlaps in the drainage groove 2211, reduce the probability of adjacent tiles 3 being too far apart, and improve structural stability.

[0062] One or more embodiments of this application disclose a photovoltaic system, with reference to... Figure 8 The photovoltaic tile 5 includes the photovoltaic tile 5 and the tile mounting structure of any of the above embodiments, wherein the photovoltaic tile 5 is adapted to be connected and fixed by the tile mounting structure.

Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application.
