Description

Technical Field

[0001] This utility model relates to the field of photovoltaic technology, specifically to a photovoltaic tile connection device, a photovoltaic tile assembly, and a photovoltaic roof. Background Technology

[0002] Currently, most photovoltaic (PV) roof tiles are made of metal, which are overlapped. Stepping on these metal tiles during installation can easily cause deformation at the overlap, affecting the overall aesthetics of the roof. Furthermore, because the overlap is not fully secured laterally, misalignment is common during installation. In addition, PV tiles need to be cut to fit the edge shape during installation. However, these cut tiles often fail to form a stable and effective overlap with adjacent tiles, especially since some cut tiles are too small and prone to detachment. This results in a low tolerance for installation errors, increased labor costs for adjustments, and hinders rapid installation. Utility Model Content

[0003] This utility model aims to solve the problems of easy deformation at the overlap of photovoltaic tiles, inability to form an effective and stable overlap, and low installation error tolerance in related technologies. In view of this, this utility model provides a photovoltaic tile connection device, a photovoltaic tile assembly, and a photovoltaic roof, which can prevent misalignment and form an effective and stable connection, thereby improving the installation error tolerance.

[0004] In a first aspect, this utility model provides a photovoltaic tile connection device, comprising: a first overlapping member having a first connecting portion and a first fastening portion, the first fastening portion being disposed on one side of the first connecting portion, the first fastening portion having a first barb groove, the opening of the first barb groove facing the first connecting portion; a second overlapping member having a second connecting portion and a second fastening portion, the second fastening portion being disposed on one side of the second connecting portion, the second fastening portion having a second barb groove; the opening of the second barb groove facing the second connecting portion; the first overlapping member can be inserted into the second overlapping member, and when the first overlapping member and the second overlapping member are inserted, the second barb groove and the first barb groove fasten into each other.

[0005] In the above technical solution, the plug-in connection method is adopted, which is simple to install and makes it easy to form a whole row of photovoltaic tiles. The photovoltaic tiles will not overlap and cause misalignment, thus improving the installation error tolerance. When the first and second overlapping parts are plugged in, the groove walls and groove bodies of the first and second hook grooves form a "mortise and tenon" interlocking structure. On the one hand, it enhances the deformation resistance of the plug joint, thus avoiding the impact on the flatness and aesthetics of the roof due to deformation at the plug joint. On the other hand, the first and second hook grooves restrain each other in the lateral direction, which can effectively resist lateral displacement and prevent the photovoltaic tiles from being misaligned and falling off due to wind impact. In addition, the interlocking structure can also form a tortuous sealing path, using the "maze effect" to block water seepage, thereby reducing the risk of rainwater intrusion and improving the waterproof performance of the plug joint.

[0006] In some technical solutions, optionally, the first fastening part includes: a first vertical edge, one end of which is connected to the first connecting part and located on one side of the first connecting part; a first fastening edge, which is connected to the first vertical edge and extends from the first vertical edge to the other side of the first connecting part; a second fastening edge, which is connected to the first fastening edge and extends from the first fastening edge to the first connecting part; the second fastening edge and the first connecting part define a first gap groove; the first vertical edge, the first fastening edge and the second fastening edge together define a first barb groove, and the first barb groove communicates with the first gap groove.

[0007] In the above technical solution, the first fastening edge and the first connecting part restrict the vertical movement of the second overlapping piece from the top and bottom directions, while the first standing edge and the second fastening edge restrict the lateral movement of the second overlapping piece from both sides, thereby preventing the first overlapping piece and the second overlapping piece from misaligning and falling off, and greatly improving the stability and reliability of the connection.

[0008] In some technical solutions, optionally, the first standing edge is flush with one side of the first connecting part; and / or the first fastening edge is parallel to the first connecting part and flush with the end face of the first standing edge away from the first connecting part; and / or the second fastening edge is parallel to the first standing edge and flush with the end face of the first fastening edge away from the first standing edge.

[0009] In this way, on the one hand, the area of ​​the non-plug area can be reduced, which is conducive to improving the reliability of the connection at the plug point; on the other hand, it makes the appearance neater and more beautiful.

[0010] In some technical solutions, optionally, the second fastening portion includes: a second vertical edge connected to the second connecting portion and located on one side of the second connecting portion; a third fastening edge connected to the second vertical edge and extending from the second vertical edge to the other side of the second connecting portion; a fourth fastening edge connected to the third fastening edge and extending from the third fastening edge to the second connecting portion; the fourth fastening edge and the second connecting portion define a second gap groove; the second vertical edge, the third fastening edge and the fourth fastening edge together define a second barb groove, and the second barb groove communicates with the second gap groove.

[0011] This can further improve the stability and reliability of the connection, preventing the first and second overlapping parts from misaligning and falling off.

[0012] In some technical solutions, optionally, the second standing edge is flush with one side of the second connecting part; and / or the third fastening edge is parallel to the second connecting part and flush with the end face of the second standing edge away from the second connecting part; and / or the fourth fastening edge is parallel to the second standing edge and flush with the end face of the third fastening edge away from the second standing edge.

[0013] In this way, on the one hand, the area of ​​the non-plug area can be further reduced, which is conducive to improving the reliability of the connection at the plug point; on the other hand, it makes the appearance neater and more beautiful.

[0014] In some technical solutions, optionally, when the first lap joint and the second lap joint are inserted, one side of the first connecting part and the second fastening part are pressed together, and one side of the second connecting part and the first fastening part are pressed together.

[0015] This can further improve the stability of the plug-in structure.

[0016] Secondly, this utility model provides a photovoltaic tile matching device, including the photovoltaic tile matching connection device as provided in any of the above technical solutions. Therefore, the photovoltaic tile matching device possesses all the beneficial effects of any of the above technical solutions, which will not be elaborated further here.

[0017] In some technical solutions, the photovoltaic tile can optionally have a backlight side and a light-receiving side; wherein, a first overlapping member is disposed on one side of the photovoltaic tile, and a second overlapping member is disposed opposite to the other side of the photovoltaic tile; wherein, the openings of the first barb groove and the second barb groove are opposite and face the backlight side and the light-receiving side respectively.

[0018] In this way, a lot of time does not need to be spent adjusting the position and angle of the photovoltaic tiles during installation, which greatly simplifies the installation process.

[0019] In some technical solutions, optionally, the other side of the first connecting part and the other side of the second connecting part are connected to the photovoltaic tile, and one of the first connecting part and the second connecting part is coplanar with the backlight surface, while the other is coplanar with the light-receiving surface.

[0020] In this way, the joint is integrated with the surface of the photovoltaic tile, without any obvious protrusions or depressions, making the photovoltaic tile look flatter and neater.

[0025] The technical solutions of the present utility model will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0026] The terms "first," "second," etc., used in the specification and claims of this utility model are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of this utility model can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, the first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0027] Currently, most photovoltaic (PV) roof tiles are installed using an overlapping method on both sides. During installation, workers need to step on the tiles, which can easily cause deformation at the overlap, affecting the overall aesthetics of the roof. Furthermore, because the overlap is not fully secured laterally, misalignment is common during installation. Additionally, when installing at the roof edges, the tiles need to be cut to fit the boundary shape. However, the cut tiles often fail to form a stable and effective overlap with adjacent tiles, especially since some cut tiles are too small and prone to detachment. This results in a low tolerance for installation errors, increased labor costs for adjustments, and hinders rapid installation.

[0028] In view of this, in order to solve the problem of easy deformation and inability to form an effective and stable overlap at the overlap of photovoltaic tiles in related technologies, this utility model provides a photovoltaic tile connection device, including: a first overlap member and a second overlap member. The first overlap member has a first connecting portion and a first fastening portion, the first fastening portion is disposed on one side of the first connecting portion, and the first fastening portion has a first barb groove, the opening of the first barb groove facing the first connecting portion. The second overlap member has a second connecting portion and a second fastening portion, the second fastening portion is disposed on one side of the second connecting portion, the second fastening portion has a second barb groove, the opening of the second barb groove facing the second connecting portion. The first overlap member and the second overlap member can be inserted into each other, and during insertion, the second barb groove and the first barb groove fasten together.

[0029] In practical applications, adjacent photovoltaic (PV) tiles are joined together via a first and a second hook groove. Installation is simple, easily forming a whole row of PV tiles without overlapping or misalignment, thus improving installation tolerance. During joining, the walls and bottoms of the first and second hook grooves form a mortise and tenon joint, enhancing the deformation resistance at the joint and preventing deformation from affecting roof flatness and aesthetics. Furthermore, the mutual restraint of the first and second hook grooves in the lateral direction effectively resists lateral displacement, preventing the PV tiles from shifting and falling off due to wind impact. This ensures effective connection regardless of the size of the PV tiles. Additionally, it helps improve the waterproofing of the joint area, reducing the risk of rainwater intrusion.

[0030] It is understood that the photovoltaic tile connection device provided in this embodiment of the present invention can be used to connect adjacent photovoltaic tiles, or it can be used for the installation of other components, such as various boards.

[0031] The photovoltaic tile and its matching material provided in this embodiment can be used in various photovoltaic roofs or photovoltaic power generation systems that require the use of photovoltaic tiles and matching materials. Photovoltaic roofs include, but are not limited to, the roofs of various buildings such as buildings, industrial plants, and public facilities.

[0032] The following is combined with Figures 1 to 3 The present invention will provide a detailed description of the photovoltaic tile connection device, photovoltaic tile distribution device, and photovoltaic roof provided by the present invention through specific embodiments and application scenarios.

[0033] Reference Figure 1 and Figure 2 This utility model provides a photovoltaic tile connection device 100, including: a first overlapping member 110 and a second overlapping member 120.

[0034] The first overlapping member 110 has a first connecting portion 111 and a first fastening portion 112. The first fastening portion 112 is disposed on one side of the first connecting portion 111, and the first fastening portion 112 has a first barb groove 113, the opening of the first barb groove 113 facing the first connecting portion 111. The second overlapping member 120 has a second connecting portion 121 and a second fastening portion 122. The second fastening portion 122 is disposed on one side of the second connecting portion 121, and the second fastening portion 122 has a second barb groove 123, the opening of the second barb groove 123 facing the second connecting portion 121.

[0035] The first overlapping member 110 can be inserted into the second overlapping member 120. When the first overlapping member 110 can be inserted into the second overlapping member 120, the first barb groove 113 and the second barb groove 123 are engaged with each other.

[0036] Specifically, the first connecting member 110 is composed of a first connecting part 111 and a first fastening part 112. The first connecting part 111 is used to connect with the photovoltaic tile and serves as the main support. The first fastening part 112 serves as a male plug interface and has a first barb groove 113 with its opening facing the first connecting part 111, forming a groove structure facing away from the first connecting part 111, which is used to form half of the interlocking structure.

[0037] The second connector 120 consists of a second connecting part 121 and a second fastening part 122. The second connecting part is used to connect with the photovoltaic tile and serves as the main support. The second fastening part 122 serves as a female plug-in interface and has a second barb groove 123 with an opening facing the second connecting part 121, forming a groove structure facing away from the second connecting part 121, which is used to form the other half of the interlocking structure.

[0038] When the first overlapping member 110 and the second overlapping member 120 are inserted, the groove walls and bodies of the first barbed groove 113 and the second barbed groove 123 form a "mortise and tenon" interlocking structure. On the one hand, this enhances the deformation resistance of the insertion point, thus preventing deformation from affecting the flatness and aesthetics of the roof. On the other hand, the first barbed groove 113 and the second barbed groove 123 mutually restrain each other in the lateral direction, effectively resisting lateral displacement and preventing the photovoltaic tile 200 from shifting and falling off due to wind impact. An effective connection can be formed regardless of the size of the photovoltaic tile 200. Furthermore, the interlocking structure can also form a tortuous sealing path, using the "maze effect" to block water seepage, thereby reducing the risk of rainwater intrusion and improving the waterproof performance of the insertion point.

[0039] In the above embodiments, the plug-in connection method is adopted, which is simple to install and makes it easy to form the entire row of photovoltaic tiles 200 into a whole. The photovoltaic tiles 200 will not overlap and cause misalignment, thereby improving the installation error tolerance rate.

[0040] In some embodiments, the first fastening portion 112 includes a first standing edge 1121, a first fastening edge 1122, and a second fastening edge 1123.

[0041] One end of the first upright edge 1121 is connected to the first connecting portion 111 and is located on one side of the first connecting portion 111. The first fastening edge 1122 is connected to the first upright edge 1121 and extends from the first upright edge 1121 to the other side of the first connecting portion 111. The second fastening edge 1123 is connected to the first fastening edge 1122 and extends from the first fastening edge 1122 to the first connecting portion 111; the second fastening edge 1123 and the first connecting portion 111 define a first gap groove 1124. The first upright edge 1121, the first fastening edge 1122 and the second fastening edge 1123 together define a first barb groove 113. The first barb groove 113 and the first gap groove 1124 are in communication.

[0042] Specifically, the first vertical edge 1121 protrudes from one side of the first connecting portion 111 and extends away from the first connecting portion 111, that is, extends upward, to form an L-shaped cavity area with the first connecting portion 111. Its height determines the depth and strength of the interlocking structure. The first vertical edge 1121 serves as a retaining edge, on the one hand, preventing rainwater from seeping in; on the other hand, the first vertical edge 1121 can cooperate with the second overlapping member 120 to prevent the second overlapping member 120 from moving laterally toward the first vertical edge 1121.

[0043] The end of the first fastening edge 1122 extends laterally, that is, it extends toward the other side of the first connecting portion 111. The first fastening edge 1122 serves as the main bearing surface for pressure, which can prevent the second overlapping member 120 from moving upward.

[0044] The end of the second fastening edge 1123 extends downward toward the surface of the first connecting portion 111; a gap is left between the end of the second fastening edge 1123 and the surface of the first connecting portion 111, forming a first gap groove 1124, which serves as a guide channel for the second overlapping member 120. The second fastening edge 1123 acts as a retaining edge, preventing the second overlapping member 120 from moving laterally toward the second fastening edge 1123. Furthermore, the end of the second fastening edge 1123 can further assist the first fastening edge 1122, jointly preventing the second overlapping member 120 from moving upward.

[0045] During assembly, the second fastening part 122 of the second overlapping member 120 slides into the first barb groove 113 along the first gap groove 1124. The second barb groove 123 and the first barb groove 113 engage with each other to form a mechanical interlock. The first fastening edge 1122 and the first connecting part 111 restrict the vertical movement of the second overlapping member 120 from the top and bottom directions, respectively. The first vertical edge 1121 and the second fastening edge 1123 restrict the lateral movement of the second overlapping member 120 from both sides, thereby preventing the first overlapping member 110 and the second overlapping member 120 from misaligning and falling off, which greatly improves the stability and reliability of the connection.

[0046] In the above embodiment, the first vertical edge 1121 and one side of the first connecting portion 111 are flush. In this way, on the one hand, the appearance of the first overlapping member 110 is neater and more aesthetically pleasing; on the other hand, it can reduce the extra space occupied by the first overlapping member 110, making the insertion area more compact, thereby reducing the area of ​​the non-insertion area and improving the reliability of the connection at the insertion point.

[0047] In some embodiments, the first snap edge 1122 is parallel to the first connecting portion 111 and flush with the end face of the first vertical edge 1121 facing away from the first connecting portion 111. When the second overlapping member 120 applies pressure to the first snap edge 1122, due to the parallel relationship, the force can be transmitted more evenly to the first snap edge 1122, thereby improving the stability of the entire connection area. In addition, the appearance of the first overlapping member 110 can be made neater and more aesthetically pleasing.

[0048] In some embodiments, the second snap edge 1123 is parallel to the first upright edge 1121 and flush with the end face of the first snap edge 1122 that is away from the first upright edge 1121. When the second snap edge 1123 receives pressure from the second overlap 120, due to the parallel relationship, the force can be transmitted more evenly to the second snap edge 1123, thereby further improving the stability of the entire connection area.

[0049] In the above embodiment, the first barb groove 113 is square in shape. It is understood that the shape of the first barb groove 113 can also be other forms, such as wedge-shaped, and this embodiment is not limited thereto.

[0050] In some embodiments, the second fastening portion 122 includes a second standing edge 1221, a third fastening edge 1222, and a fourth fastening edge 1223.

[0051] The second standing edge 1221 is connected to the second connecting portion 121 and is located on one side of the second connecting portion 121. The third fastening edge 1222 is connected to the second standing edge 1221 and extends from the second standing edge 1221 to the other side of the second connecting portion 121. The fourth fastening edge 1223 is connected to the third fastening edge 1222 and extends from the third fastening edge 1222 to the second connecting portion 121; the fourth fastening edge 1223 and the second connecting portion 121 define a second gap groove 1224. The second standing edge 1221, the third fastening edge 1222 and the fourth fastening edge 1223 enclose and define a second barb groove 123, which communicates with the second gap groove 1224.

[0052] Specifically, the second vertical edge 1221 protrudes from one side of the second connecting portion 121 and extends in a direction away from the second connecting portion 121, that is, downward, to form an L-shaped cavity area with the second connecting portion 121. The second vertical edge 1221 serves as a retaining edge, on the one hand, preventing rainwater from seeping in; on the other hand, the second vertical edge 1221 can cooperate with the first overlapping member 110 to prevent the first overlapping member 110 from moving laterally toward the second vertical edge 1221.

[0053] The end of the third fastening edge 1222 extends laterally, that is, it extends toward the other side of the second connecting part 121. As the main bearing surface of the pressure, the third fastening edge 1222 can prevent the first overlapping part 110 from moving downward.

[0054] The end of the fourth fastening edge 1223 extends upward toward the surface of the second connecting portion 121; a gap is left between the end of the fourth fastening edge 1223 and the surface of the second connecting portion 121, forming a second gap groove 1224, which serves as a guide channel for the first overlapping member 110. The fourth fastening edge 1223 acts as a retaining edge, preventing the first overlapping member 110 from moving laterally toward the fourth fastening edge 1223. Furthermore, the end of the fourth fastening edge 1223 can further assist the third fastening edge 1222, jointly preventing the first overlapping member 110 from moving downward.

[0055] During assembly, the first fastening part 112 of the first overlapping member 110 slides into the second barb groove 123 along the second gap groove 1224. The second barb groove 123 and the first barb groove 113 engage with each other to form a mechanical interlock, thereby preventing the first overlapping member 110 and the second overlapping member 120 from misaligning and falling off, which greatly improves the stability and reliability of the connection.

[0056] In some embodiments, the second vertical edge 1221 and one side of the second connecting portion 121 are flush. In this way, on the one hand, the appearance of the second overlapping member 120 can be made neater and more aesthetically pleasing; on the other hand, it can reduce the extra space occupied by the first overlapping member 120, making the insertion area more compact, thereby reducing the area of ​​the non-insertion area and improving the reliability of the connection at the insertion point.

[0057] In some embodiments, the third snap edge 1222 is parallel to the second connecting portion 121 and flush with the end face of the second standing edge 1221 that is away from the second connecting portion 121. When the first overlapping member 110 applies pressure to the third snap edge 1222, the force can be transmitted more evenly to the third snap edge 1222 due to the parallel relationship, thereby improving the stability of the entire connection area.

[0058] The fourth snap edge 1223 is parallel to the second upright edge 1221 and flush with the end face of the third snap edge 1222 that is away from the second upright edge 1221. When the fourth snap edge 1223 receives pressure from the first overlapping member 110, due to the parallel relationship, the force can be transmitted to the fourth snap edge 1223 more evenly, thereby further improving the stability of the entire connection area.

[0059] In the above embodiment, the second barb groove 123 is square in shape. It is understood that the shape of the second barb groove 123 can also be other forms, such as wedge-shaped, and this embodiment is not limited thereto.

[0060] In the above embodiment, when the first overlapping member 110 and the second overlapping member 120 are inserted, one side of the first connecting portion 111 and the second fastening portion 122 are pressed together. One side of the second connecting portion 121 is pressed together with the first fastening portion 112.

[0061] Specifically, the first connecting part 111 and the third fastening edge 1222 are tightly abutted. The second connecting part 121 and the first fastening edge 1122 are tightly abutted. The first standing edge 1121 and the fourth fastening edge 1223 are tightly abutted. The second standing edge 1221 and the second fastening edge 1123 are tightly abutted.

[0062] In the above embodiments, the tightly fitted design of the components of the connecting device ensures that the components support and constrain each other when the plug-in structure is subjected to external forces. This prevents misalignment or separation during use, thereby further improving the stability of the plug-in structure.

[0063] In some embodiments, the first overlap 110 may be a one-piece molded structure. Similarly, the second overlap 120 may also be a one-piece molded structure.

[0064] Reference Figure 1 and Figure 2 In some embodiments, the present invention also provides a photovoltaic tile adapter 200, including the photovoltaic tile adapter connection device 100 provided in any of the above embodiments. Therefore, the photovoltaic tile adapter 200 has all the beneficial effects of any of the above embodiments, which will not be repeated here.

[0065] In some embodiments, the photovoltaic tile 200 has a backlight surface 210 and a light-receiving surface 220. A first overlapping member 110 is disposed on one side of the photovoltaic tile 200, and a second overlapping member 120 is disposed opposite to the other side of the photovoltaic tile 200. The openings of the first barbed groove 113 and the second barbed groove 123 are opposite and face the backlight surface 210 and the light-receiving surface 220, respectively.

[0066] When two adjacent photovoltaic tile pieces 200 are interlocked, the first overlapping member 110 of one photovoltaic tile piece 200 and the second overlapping member 120 of the other photovoltaic tile piece 200 interlock, thereby achieving the interlocking of the two adjacent photovoltaic tile pieces 200. This not only simplifies the installation process but also ensures that the two adjacent photovoltaic tile pieces 200 will not misalign or fall off, providing a good fixing effect; even when installed at the edge, they will not fall off.

[0067] In the above embodiment, a first overlapping member 110 and a second overlapping member 120 are respectively provided on opposite sides of the photovoltaic tile 200, and the openings of the first barbed groove 113 and the second barbed groove 123 are opposite and face the backlight surface 210 and the light-receiving surface 220 respectively. In this way, during installation, it is only necessary to align the first overlapping member 110 of one photovoltaic tile 200 with the second overlapping member 120 of the adjacent photovoltaic tile 200 to quickly and accurately complete the initial positioning, without spending a lot of time adjusting the position and angle of the photovoltaic tile 200, thereby greatly simplifying the installation process.

[0068] It is understandable that photovoltaic tiles with a 200mm jack can be metal tiles, such as aluminum tiles or steel tiles.

[0069] In some embodiments, the other side of the first connecting portion 111 and the other side of the second connecting portion 121 are connected to the photovoltaic tile 200, and one of the first connecting portion 111 and the second connecting portion 121 is coplanar with the backlight surface 210, while the other is coplanar with the light-receiving surface 220. In this way, the insertion point and the surface of the photovoltaic tile 200 can be on the same plane and integrated as one, without obvious protrusions or depressions, making the photovoltaic tile 200 look flatter and neater.

[0070] It is understandable that the first connector 110 and the second connector 120 can be integrally formed with the photovoltaic tile 200.

[0071] Reference Figures 1 to 3 In some embodiments, the present invention also provides a photovoltaic roof 300, including a substrate 310 and photovoltaic tile assemblies 200. The photovoltaic tile assemblies 200 are disposed on the substrate 310. Adjacent photovoltaic tile assemblies 200 are interlocked using the photovoltaic tile assembly connecting device 100 provided in any of the above embodiments; and / or, the photovoltaic tile assemblies 200 are the photovoltaic tile assemblies 200 provided in any of the above embodiments. Thus, the photovoltaic roof 300 possesses all the beneficial effects of any of the above embodiments, which will not be elaborated further here.

[0072] Understandably, the 300 photovoltaic roof also includes photovoltaic tiles.

[0073] The photovoltaic tile and the photovoltaic tile adapter 200 can also be connected by the photovoltaic tile adapter connection device 100. For example, the photovoltaic tile is provided with a first overlapping member 110 to be connected with a second overlapping member 120 on the photovoltaic tile adapter 200.
