Description

[0002] With the rapid development of the BIPV (photovoltaic building integration) market in recent years, the application scenarios are becoming more and more abundant. According to the application scenarios, there are mainly photovoltaic curtain walls, photovoltaic skylights, photovoltaic sunshade corridors, rooftop photovoltaic tiles and other application scenarios (such as photovoltaic railings, photovoltaic floor tiles, etc.). The connection between photovoltaic tile components takes into account the installation and waterproofing requirements. Generally, rubber parts are used for overlap. During installation, the tightness between the rubber parts is ensured by tightening in other positions to achieve the waterproof effect. The rubber parts themselves do not play a tightening role. In this solution, the high friction coefficient of the rubber parts leads to installation difficulties or the rubber strips fall off. During installation, it is often necessary to adjust the left and right distances to achieve the expected waterproof effect.

[0038] See Figures 1 to 5 , an embodiment of the present invention provides a photovoltaic tile connector for use in a photovoltaic roof, the photovoltaic roof including a first photovoltaic tile assembly 200 and a second photovoltaic tile assembly 300 arranged adjacent to each other, the photovoltaic tile connector including a cover plate 110 and a connecting portion 120, the cover plate 110 covers the gap between the adjacent first photovoltaic tile assembly 200 and the second photovoltaic tile assembly 300, and both sides of the cover plate 110 cover the side ends of the first photovoltaic tile assembly 200 and the second photovoltaic tile assembly 300; the connecting portion 120 is connected to the cover plate 110, and the connecting portion 120 is respectively engaged with the adjacent frames of the first photovoltaic tile assembly 200 and the second photovoltaic tile assembly towards both ends of the first photovoltaic tile assembly 200 and the second photovoltaic tile assembly 300.

[0039] This technical solution provides a photovoltaic tile connector for connecting adjacent first and second photovoltaic tile assemblies 200 and 300 on a photovoltaic roof. The photovoltaic tile connector includes a cover plate 110 and a connector portion 120. The cover plate 110 covers the gap between the adjacent first and second photovoltaic tile assemblies 200 and 300, and the two sides of the cover plate 110 cover the side ends of the first and second photovoltaic tile assemblies 200 and 300 to block rainwater, thereby preventing rainwater from flowing into the gap between the first and second photovoltaic tile assemblies 200 and 300. The connector portion 120 is provided on the cover plate 110 and snap-fitted to the frames of the first and second photovoltaic tile assemblies 200 and 300 to achieve connection between the connector portion 120 and the first and second photovoltaic tile assemblies 200 and 300. This connector can connect two adjacent photovoltaic tile assemblies and protect the gap between the two photovoltaic tile assemblies from rain. The snap-fit method provides easy installation and reliable connection.

[0040] like Figures 2 to 5 As shown, specifically, the connecting portion 120 includes a first connecting plate 121, a limiting plate 122 and a second connecting plate 123, one end of the first connecting plate 121 is fixedly connected to the cover plate 110, and the other end extends in a direction away from the cover plate 110; the two limiting plates 122 are arranged at intervals and are respectively arranged on opposite sides of the first connecting plate 121; the second connecting plate 123 is fixedly connected to one end of the first connecting plate 121 away from the cover plate 110, wherein the opposite ends of the second connecting plate 123 are respectively fixedly connected to the two limiting plates 122, and the limiting plates 122 are accommodated in the limiting cavity 214 of the frame.

[0041] In this embodiment, the first connecting plate 121 is used to connect the second connecting plate 123 to the cover plate 110, and the second connecting plate 123 is used to connect the limiting plate 122. The limiting plate 122 is used to cooperate with the frame to achieve mutual limitation. Specifically, the two ends of the first connecting plate 121 are respectively connected to the cover plate 110 and the second connecting plate 123, and the two ends of the second connecting plate 123 are respectively connected to the two limiting plates 122, and the second connecting plate 123 is perpendicular to the first connecting plate 121, so that the two limiting plates 122 are spaced apart from each other, so that the two limiting plates 122 can respectively cooperate with the limiting cavity 214 of the frame of the adjacent first photovoltaic tile assembly 200 and the second photovoltaic tile assembly 300. The structure of the two limiting plates 122 is matched with the structure of the limiting cavity 214, so as to achieve mutual limitation between the limiting plates 122 and the frame, and then the first photovoltaic tile assembly 200 and the second photovoltaic tile assembly 300 are connected through the connecting portion 120.

[0042] Furthermore, the cover plate 110 and the connecting portion 120 are integrally formed. Specifically, the photovoltaic tile connector is made of aluminum alloy and formed integrally by hot extrusion. This molding method, on the one hand, achieves a near-final finish on the photovoltaic tile connector, reducing production costs, and on the other hand, ensures a more reliable and stronger connection between the various parts of the photovoltaic tile connector.

[0043] like Figures 3 and 4 As shown, in one embodiment, the two ends of the two limiting plates 122 extend in a direction away from the second connecting plate 123 respectively, and the ends of the two limiting plates 122 facing away from the cover plate 110 together with the second connecting plate 123 define a limiting groove 124, and the limiting groove 124 is used to clamp the first side edge 212 of the frame setting of the first photovoltaic tile assembly 200 and the second photovoltaic tile assembly 300.

[0044] The ends of the two limiting plates 122 are extended away from the second connecting plate 123 so that both ends of the limiting plates 122 abut against the side edges of the frame to achieve mutual restraint. The two limiting plates 122 and the second connecting plate 123 jointly define a limiting groove 124, so that the first side edges 212 of the frames of the two photovoltaic tile assemblies are both retained in the limiting groove 124. While the two limiting plates 122 retain the two first side edges 212, installation and connection are facilitated.

[0045] Specifically, the ends of the limiting plate 122 respectively contact the upper and lower inner walls of the limiting cavity in the height direction of the frame, and the left and right sides of the limiting plate contact the left and right inner walls of the limiting cavity. By clamping in two directions, the connection between two adjacent photovoltaic modules is achieved. The photovoltaic tile connector is inserted from the side of the photovoltaic tile module along the photovoltaic tile frame to connect the adjacent photovoltaic tile modules and seal the joint. Compared with the existing technology, the operation is more convenient.

[0046] like Figure 2 As shown, in another embodiment, the end of the first connecting plate 121 away from the cover plate 110 can also be extended toward the end away from the second connecting plate 123, and extended to be flush with the end of the limiting plate 122. In this way, the limiting plate 122, the second connecting plate 123 and the first connecting plate 121 at the end away from the cover plate 110 jointly enclose two spaced limiting grooves 124, and the first side edges 212 of the frames of two adjacent photovoltaic tile assemblies are respectively opened in the two limiting grooves 124 to achieve mutual limitation.

[0047] like Figure 4 and Figure 5As shown, in one embodiment, at least one limiting protrusion 1221 is provided on the side surface of each of the two limiting plates 122 located within the limiting groove 124, and the limiting protrusion 1221 abuts against the first side edge 212 of the frame. By providing the limiting protrusion 1221 on the limiting plate 122 and abutting the limiting protrusion 1221 against the first side edge 212 of the frame, the limiting performance of the limiting plate 122 on the first side plate is improved, thereby improving the reliability of the connection between the connector and the frame of the photovoltaic tile assembly. In another embodiment, at least one limiting protrusion 1221 can also be provided on the first side edge 212 of the frame, and the limiting protrusion 1221 abuts against the side surface of the limiting plate 122 located within the limiting groove 124.

[0048] like Figure 4 and Figure 5 As shown, in one embodiment, the two sides of the first connecting plate 121 respectively define two accommodating grooves 125 with the two limiting plates 122 and the second connecting plate 123. The two accommodating grooves 125 are respectively used to clamp the second side edges 213 set on the frame of the first photovoltaic tile assembly 200 and the second photovoltaic tile assembly 300, and are respectively clamped in the two accommodating grooves 125; the first side edge 212 and the outer wall of the frame, and / or the second side edge 213 and the outer wall of the frame form a limiting cavity; the first side edge 212 is at the lower part of the second side edge 213.

[0049] Two accommodating grooves 125 are formed at one end facing the cover plate 110 by the limiting plate 122, the second connecting plate 123 and the first connecting plate 121, so that the second side edges 213 of the frames in two adjacent photovoltaic tile assemblies can be clamped in the accommodating grooves 125, thereby limiting the second side edges 213 by the limiting plate 122 and the first connecting plate 121, thereby realizing the connection between the connecting part 120 and the first photovoltaic tile assembly 200 and the second photovoltaic tile assembly 300.

[0050] like Figures 1 to 5As shown, in one embodiment, the photovoltaic connector 100 further includes a sealing strip 130, and the two sealing strips 130 are fixedly connected to both sides of the cover plate 110, and abut against the upper surface of the frame of the first photovoltaic tile assembly 200 and the second photovoltaic tile assembly 300 or the photovoltaic laminated member near the frame. Furthermore, the sealing strip 130 is bonded to the cover plate 110. By fixing the sealing strip 130 on both sides of the cover plate 110 and abutting the sealing strip 130 against the first photovoltaic tile assembly 200 and the second photovoltaic tile assembly 300, so as to be connected to the frames of two adjacent photovoltaic tile assemblies through the connecting portion 120, the sealing strip 130 is pressed between the cover plate 110 and the photovoltaic tile assembly, thereby sealing the gap between the cover plate 110 and the photovoltaic tile assembly, thereby preventing rainwater from flowing into the roof through the gap between the two photovoltaic tile assemblies. By bonding the sealing strip 130 to the cover plate 110, the integration of the sealing strip 130 and the cover plate 110 is improved. During installation, the sealing strip 130 can be pressed between the cover plate 110 and the photovoltaic tile assembly by simply snapping the connecting portion 120 into the frame. This overcomes the drawbacks of the prior art that waterproof assemblies are difficult to install and prone to falling off.

[0051] The structural form of sealing strip 130 is not limited. In this embodiment, the cross-section of sealing strip 130 is a trapezoidal ring. The width of the bottom edge of sealing strip 130 that contacts cover plate 110 is greater than the width of the bottom edge that contacts the photovoltaic tile assembly. Furthermore, the bottom edge of sealing strip 130 that contacts the photovoltaic tile assembly is provided with a plurality of spaced-apart protrusions. This increases friction between sealing strip 130 and the photovoltaic tile assembly, thereby improving the sealing performance between the sealing strip 130 and the photovoltaic tile assembly.

[0052] It is understandable that the positional relationship between the sealing strip 130 and the frame is not limited. In one embodiment, for example, Figure 4 As shown, the sealing strip 130 is in contact with the upper surface of the frame, and the sealing strip 130 extends along the entire length of the photovoltaic tile connector. Figure 5 As shown, the sealing strip 130 is in contact with the photovoltaic laminate of the photovoltaic tile assembly adjacent to the frame, thereby sealing the gap between the two adjacent photovoltaic tile assemblies.

[0053] like Figure 1As shown, an embodiment of the present invention also provides a photovoltaic roof, which includes the photovoltaic connector 100 as described above, and the photovoltaic roof also includes a first photovoltaic tile assembly 200 and a second photovoltaic tile assembly 300 arranged adjacent to each other, the first photovoltaic tile assembly 200 and the second photovoltaic tile assembly 300 both include a frame, the frame includes a first side 212 and a second side 213 arranged opposite to each other, the opposite ends of the first side 212 and the second side 213 are spaced apart, and the first side 212 and the second side 213 are snap-connected with the connecting portion 120.

[0054] The first photovoltaic tile assembly 200 and the second photovoltaic tile assembly 300 also include a photovoltaic cell 220, and the frame is constructed with a mounting groove, and one end of the photovoltaic cell 220 is fixed to the mounting groove by glue filling. The opposite ends of the first side 212 and the second side 213 in the frame are spaced apart so that the opposite ends of the first side 212 and the second side 213 form an avoidance gap for being snapped with the connecting portion 120. The connection between the photovoltaic tile connector and the frame of the photovoltaic tile assembly is achieved by snapping the first side 212 and the second side 213 with the connecting portion 120. For ease of understanding, the frame in the first photovoltaic tile assembly 200 is defined as the first frame 211, and the frame in the second photovoltaic tile assembly 300 is defined as the second frame 310.

[0055] Furthermore, the frame also includes a frame body 211, a first side 212 and a second side 213 are fixedly connected to the frame body 211, and the first side 212, the side of the frame body 211 and the second side 213 together form a limiting cavity 214 with an opening on one side.

[0056] A limiting cavity 214 is formed between the frame body 211 and the first side 212 and the second side 213. The limiting plate 122 of the connecting part 120 is matched with the limiting cavity 214 to achieve mutual limitation between the connecting part 120 and the frame, thereby achieving connection between the connecting part 120 and the photovoltaic tile assembly.

[0057] Reference Figures 1 to 5 It is understood that the installation method of the photovoltaic tile connector provided by the present invention is:

[0058] When installing the photovoltaic tile connector to the photovoltaic tile assembly, the first photovoltaic tile assembly and the second photovoltaic tile assembly are pushed together, with the lower edge of the first frame of the first photovoltaic tile assembly in close contact with the lower edge of the second frame of the second photovoltaic tile assembly. Then, the connecting portion 120 of the connector is inserted into the limiting cavity of the frame from the end of the frame, and the connector is pushed along the extension direction of the frame until it is flush with the two ends of the frame. The limit plate 122 limits the possibility of left and right movement of the photovoltaic tile. At the same time, the sealing strip 130 is in close contact with the surface of the photovoltaic tile assembly, preventing rainwater from entering between two adjacent photovoltaic tile assemblies from the upper end.

[0059] When it is necessary to remove and replace one of the photovoltaic tile components, the photovoltaic tile connector assembly can be directly pulled out to achieve the disassembly of the photovoltaic tile component, which is convenient and quick.

[0060] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned 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.

[0061] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
