[0037] In the prior art, the first frame of the first photovoltaic assembly of two adjacent photovoltaic assemblies is located above the second frame of the second photovoltaic assembly, the first frame and the second frame are overlapped, and the mounting seat is pressed on the first frame and the second frame to connect the two adjacent photovoltaic assemblies. However, the first frame and the second frame are overlapped, and the mounting seat is pressed on the first frame and the second frame. There is a gap between the three, and the stability of the connection is poor. The wind can easily lift the mounting seat upward, resulting in the inability to effectively connect the first photovoltaic assembly and the second photovoltaic assembly, which is easy to shift and has poor wind resistance, so that the photovoltaic assembly connection system has safety problems.

[0038] In order to solve the above problems, the present disclosure provides a photovoltaic module connection system, referring to Figure 1 The photovoltaic component connection system mainly includes: at least two photovoltaic components 100 and a connector 200.

[0039] Each photovoltaic component 100 includes a laminate 103, a first frame 110 assembled on a first edge of the laminate 103, and a second frame 120 assembled on a second edge of the laminate 103 opposite to the first edge. The photovoltaic component 100 includes a first photovoltaic component 101 and a second photovoltaic component 102. The first frame 110 of the first photovoltaic component 101 is located above the second frame 120 of the second photovoltaic component 102.

[0040] The connector 200 includes a clamping portion 210 and a hook portion 220 . The clamping portion 210 is clamped and connected to the first frame 110 of the first photovoltaic component 101 , and the hook portion 220 is hooked and connected to the second frame 120 of the second photovoltaic component 102 .

[0041] Based on the snap connection of the snap-in portion 210 of the connector 200 and the first frame 110 of the first photovoltaic assembly 101, the hook portion 220 of the connector 200 is hook-connected with the second frame 120 of the second photovoltaic assembly 102. Through the snap connection and the hook connection, the first photovoltaic assembly 101 and the second photovoltaic assembly 102 are firmly connected, with good stability, strong wind resistance and high safety.

[0042] In the embodiment of the present disclosure, the number of the connecting member 200 can be one or more. When the number of the connecting member 200 is more than one, the multiple connecting members 200 are dispersedly arranged along the extension direction of the first frame 110. In this way, multiple positions of the first frame 110 of the first photovoltaic component 101 are respectively connected to multiple positions of the second frame 120 of the second photovoltaic component 102, which is conducive to increasing the connection strength stability between the first frame 110 and the second frame 120.

[0043] There are many ways to connect the clamping portion 210 to the first frame 110. For example, Figure 2, on the side of a part of the first frame 110 below the laminate 103 of the first photovoltaic module 101, a clamping groove 111 may be provided, and the clamping portion 210 is clamped in the clamping groove 111. This mutually cooperative clamping method between the clamping portion 210 and the clamping groove 111 is simple and more convenient for assembly.

[0044] Reference Figure 2 , Figure 3 and Figure 5 , the opening width of the clamping groove 111 of the connecting member 200 is smaller than the width of the groove bottom, as Figure 3 shown, D2 < D1. The clamping portion 210 has a plate-like structure, and the width of the clamping portion 210 is greater than the opening width of the clamping groove 111. With such a setting, after the clamping portion 210 is inserted into the clamping groove 111, the clamping portion 210 will not脱离 from the opening of the clamping groove 111, and thus the clamping portion 210 can be clamped in the clamping groove 111. With such a design, under the action of the roof wind load (suction or pressure), regardless of the direction of the suction or pressure, the clamping portion 210 of the connecting member 200 is clamped with the clamping groove 111 of the first frame 110 of the first photovoltaic module 101, forming an action and reaction force, so that the overall structure is in a static state and has strong wind uplift resistance.

[0045] The clamping portion 210 is slidably limited in the clamping groove 111, so as to enter the clamping groove 111, which is convenient for installation and disassembly. Of course, the clamping portion 210 can also be limited in the clamping groove 111 by other means. The first frame 110 is provided with an opening, which can enable the clamping portion 210 to slide into the clamping groove 111 of the first frame 110.

[0046] In addition, on the part below the laminate 103 of the second photovoltaic module 102, the side of the second frame 120 is provided with a connecting portion 121 bent downward, and the hook portion 220 hooks the connecting portion 121 upward. With such a setting, under the action of the roof wind load suction, the hook portion 220 hooks the connecting portion 121 upward and is in close contact. Since the connecting portion 121 is bent downward, it will give the hook portion 220 a downward acting force, forming an action and reaction force, so that it cannot be separated from the hook portion 220, thereby improving the wind uplift resistance of the photovoltaic module connection system.

[0047] Reference Figure 5The hook portion 220 may include a first connector 221, a second connector 222 and an inclined portion 224 connected in sequence, the first connector 221 and the second connector 222 form an angle and can both abut against the connecting portion 121, and the inclined portion 224 gradually inclines from top to bottom in a direction away from the second connector 222. The hook portion 220 has a simple structure, and the connector 200 is easy to manufacture. The inclined portion 224 gradually inclines from top to bottom in a direction away from the second connector 222, so that the opening size formed by the first connector 221, the second connector 222 and the inclined portion 224 is larger, making it easier to hook the connecting portion 121 of the second frame 120.

[0048] Furthermore, the inner surface of the inclined portion 224 can be set as a curved surface. It should be noted that the inner surface of the inclined portion 224 and the inner surface of the hook portion 220 are located on the same side, and the curved surface is a convex surface. This design makes it easy for the inclined portion 224 to slide under the connecting portion 121 during construction and installation, which is conducive to accurate assembly and positioning, and also plays the role of a drip eaves.

[0049] In addition, the inner surface of the connection between the inclined portion 224 and the second connecting body 222 can also be set as a curved surface, so that the hook portion 220 can easily hook the connecting portion 121 and facilitate assembly and disassembly.

[0050] Continue to refer Figure 5 The connector 200 may further include a third connector 223 disposed between the first connector 221 and the clamping portion 210, the third connector 223 is connected to the middle of the clamping portion 210, the third connector 223 forms an angle with the first connector 221, and the third connector 223 and the second connector 222 are located on the same side of the first connector 221. The connector 200 has a simple structure, forming a "C"-shaped structure, which is convenient for assembly with the first frame 110 of the first photovoltaic module 101 and the second frame 120 of the second photovoltaic module 102.

[0051] Furthermore, the third connector 223 can be configured as a hollow structure, which is lighter and easier to install and remove. The hollow structure can be designed in a variety of ways, for example, Figure 5 The side surface of the third connecting body 223 has a hollow triangular structure.

[0052] refer to Figure 2 , Figure 3 and Figure 6The lower surface of the first frame 110 is provided with a mounting groove 112, and the photovoltaic module connection system further includes an elastic seal 300 assembled in the mounting groove 112, and the elastic seal 300 is sealed against the laminate 103 of the second photovoltaic module 102. By assembling the elastic seal 300 with the first frame 110 of the first photovoltaic module 101 and sealing against the laminate 103 of the second photovoltaic module 102, the first photovoltaic module and the second photovoltaic module can be sealed and connected, achieving a waterproof effect.

[0053] Furthermore, the opening width of the mounting groove 112 is smaller than the width of its groove bottom, similar to the opening width D2 of the snap-in groove 111 of the connector 200 being smaller than the width of the groove bottom D1. The elastic seal 300 includes a limiting portion 301 limited in the mounting groove 112 and an abutting portion 302 connected to the middle of the limiting portion 301 and bent toward the connector 200, and the width of the limiting portion 301 is greater than the opening width of the mounting groove 112. By setting the dimensions of the mounting groove 112 and the limiting portion 301 in this way, the limiting portion 301 is not easy to be separated from the mounting groove 112, so as to facilitate the limiting portion 301 of the elastic seal 300 to be limited in the mounting groove 112. When installed, the abutting portion 302 is extremely compressed by the laminate 103 of the second photovoltaic module 102, which can play a good sealing and shock absorbing role.

[0054] In the disclosed embodiment, the material of the elastic seal 300 can be EPDM material, because it has strong corrosion resistance and good elasticity, which gives the elastic seal 300 good corrosion resistance and elasticity. Under the action of the installation pressure, the abutment portion 302 is slightly deformed. Since the elastic seal 300 itself has good elasticity, it can be in sealing contact with the glass panel of the laminate 103 of the second photovoltaic component 102. And when there is a large pressure, the first frame 110 of the first photovoltaic component 101 will not damage the glass panel of the laminate 103 of the second photovoltaic component 102, thereby making the photovoltaic component connection system safer and more reliable.

[0055] In some embodiments, the elastic seal 300 is extended parallel to the first frame 110. Since the elastic seal 300 is in a long strip structure, it can be the same length as the first frame 110 or the second frame 120, thereby completely sealing the first photovoltaic module 101 and the second photovoltaic module 102.

[0056] Continue to refer Figure 1 or Figure 2The photovoltaic module connection system provided by the embodiment of the present disclosure also includes a fixed base 500 assembled on the building, and the second frame 120 includes a connecting plate 122 extending outward from the bottom, and the connecting plate 122 is connected to the fixed base 500 through the fixing member 400. In this way, the entire photovoltaic module connection system can be fixed to the building through the fixing base 500. The fixing member 400 can be a screw, or a self-tapping bolt or other components. The fixed base 500 can be a tile hanging strip, or other components.

[0057] When the photovoltaic module 100 is a rectangular parallelepiped, the first frame and the second frame provided by the present disclosure may be either a long frame or a short frame.

[0058] Based on the above, when assembling the photovoltaic assembly connection system provided by the embodiment of the present disclosure, the first frame 110 of the first photovoltaic assembly 101 is placed above the second frame 120 of the second photovoltaic assembly 102, and the connector 200 is slid from the opening of the first frame 110 into the snap-in groove 111 of the first frame 110, and then the first photovoltaic assembly 101 and the connector 200 are pushed along the inclined direction of the laminate 103 of the second photovoltaic assembly 102, so that the elastic sealing member 300 is squeezed and compressed to seal the first photovoltaic assembly 101 and the second photovoltaic assembly 102, and the inclined portion 224 of the hook portion 220 of the connector 200 slides under the connection portion 121 of the second frame 120 of the second photovoltaic assembly 102, and the first photovoltaic assembly 101 and the connector 200 are continuously pushed, so that the hook portion 220 hooks the second frame 120 of the second photovoltaic assembly 102. In this way, the assembly between the first photovoltaic assembly 101, the second photovoltaic assembly 102 and the connector 200 is completed.

[0059] In addition, in the prior art, the connection between two adjacent photovoltaic modules also involves the matching between the first frame and the second frame, and the matching between the mounting base and the first frame and the second frame. The installation method is complicated, and size mismatch is inevitable, causing installation difficulties. The photovoltaic module connection system provided in the embodiment of the present disclosure only involves the matching connection between the connector and the first frame and the second frame, and the installation method is simple.

[0060] The above-mentioned various embodiments of the present disclosure may complement each other if no conflict occurs.

[0061] The above description is only a preferred embodiment of the present disclosure and is not intended to limit the present disclosure.
