Description

Technical Field

[0001] This utility model relates to the field of solar energy device technology, and in particular to a conductive hinge and a photovoltaic folding plate. Background Technology

[0002] In the installation and use of photovoltaic (PV) panels, multiple PV panels typically need to be electrically connected via wires to collect and transmit electrical energy. In addition to electrical connections, mechanical connections are also required between PV panels to ensure structural stability and integrity. Traditionally, separate mechanical connectors (such as screws and brackets) and wires are used for both mechanical and electrical connections. This not only increases the complexity and cost of installation but also makes subsequent maintenance and repair more cumbersome, requiring separate inspection and handling of both mechanical and electrical connections. Utility Model Content

[0003] The main purpose of this invention is to provide a conductive hinge and a photovoltaic folding plate, which aims to simplify the use of the photovoltaic folding plate.

[0004] To achieve the above objectives, the present invention proposes a conductive hinge for use in a photovoltaic folding panel, wherein the photovoltaic folding panel includes at least two photovoltaic panels, and two adjacent photovoltaic panels are rotatably connected by the conductive hinge, the conductive hinge comprising:

[0005] The hinge body includes a first hinge piece and a second hinge piece that are rotatably connected, and the first hinge piece and the second hinge piece are respectively connected to the two photovoltaic panels;

[0006] An electrical connection module includes a soft rubber sleeve and a conductive wire disposed within the soft rubber sleeve. One end of the soft rubber sleeve is connected to a photovoltaic panel via a first hinge piece, and the other end of the soft rubber sleeve is connected to another photovoltaic panel via a second hinge piece. The conductive wire is electrically connected to the two photovoltaic panels connected to the hinge body.

[0007] In one embodiment, the photovoltaic panel has a protective frame around its circumference, the protective frame has an installation notch, the soft rubber sleeve is inserted into the installation notch, and the first hinge piece and the second hinge piece are connected to both ends of the installation notch and cover the installation notch.

[0008] In one embodiment, the soft rubber sleeve has a folding groove on one side near the hinge body, and there are two folding grooves, which are respectively located near the edges of the protective frames of the two photovoltaic panels.

[0009] In one embodiment, the soft rubber sleeve has a slot on the side away from the hinge body, one sidewall of the slot engages with the edge of the mounting notch of one of the protective frames, and the other opposite sidewall of the slot engages with the edge of the call number mounting notch of another of the protective frames.

[0010] In one embodiment, the mounting notch is provided with at least two connection pins, which are electrically connected to the conductive wire.

[0011] In one embodiment, the connection pin includes a first bent segment, a second bent segment, and a third bent segment formed by bending in sequence. The first bent segment and the third bent segment extend within the mounting notch toward another mounting notch. The second bent segment extends in the thickness direction of the protective frame. The first bent segment is connected to the photovoltaic panel, and the third bent segment is connected to the conductive wire.

[0012] In one embodiment, the protective frame is made of metal, and the conductive hinge has an insulating element disposed between the connecting pin and the side wall of the mounting notch.

[0013] In one embodiment, the insulating member is provided with an insulating partition, which is disposed between two adjacent connection pins.

[0014] In one embodiment, the hinge body further includes a first bushing assembly and a second bushing assembly.

Specifically, the hinge body achieves mechanical connection between the photovoltaic panels, while the soft rubber sleeve sandwiched between the photovoltaic panel and the hinge body, along with the conductive wire within the soft rubber sleeve, enables electrical connection between the photovoltaic panels. When the photovoltaic folding panel is unfolded, the first and second hinge pieces are far apart, and the soft rubber sleeve is unfolded, protecting the conductive wire from external environmental interference.

[0031] This utility model proposes a conductive hinge.

[0032] Please see Figures 1 to 4 In one embodiment of this utility model, the conductive hinge 100 is used for a photovoltaic folding panel, which includes at least two photovoltaic panels 200, and two adjacent photovoltaic panels 200 are rotatably connected by the conductive hinge 100. The conductive hinge 100 includes:

[0033] The hinge body 11 includes a first hinge piece 111 and a second hinge piece 112 that are rotatably connected. The first hinge piece 111 and the second hinge piece 112 are respectively connected to two photovoltaic panels 200.

[0034] The electrical connection module 12 includes a soft rubber sleeve 121 and a conductive wire 124 disposed inside the soft rubber sleeve 121. One end of the soft rubber sleeve 121 is connected to a photovoltaic panel 200 through a first hinge piece 111, and the other end of the soft rubber sleeve 121 is connected to another photovoltaic panel 200 through a second hinge piece 112. The conductive wire 124 is electrically connected to the two photovoltaic panels 200 connected to the hinge body 11.

[0035] In this invention, the conductive hinge 100 achieves both mechanical connection and electrical conductivity between adjacent photovoltaic panels 200, simplifying the installation and use of the photovoltaic folding panel, allowing it to be used immediately upon unfolding. Specifically, the hinge body 11 provides the mechanical connection between the photovoltaic panels 200, while the soft rubber sleeve 121 sandwiched between the photovoltaic panel 200 and the hinge body 11, and the conductive wire 124 within the soft rubber sleeve 121, enable the electrical connection between the photovoltaic panels 200. When the photovoltaic folding panel is unfolded, the first hinge piece 111 and the second hinge piece 112 are far apart, and the soft rubber sleeve 121 is unfolded, protecting the conductive wire 124 from external environmental interference. When the photovoltaic folding panel is folded, the first hinge piece 111 and the second hinge piece 112 are close together, and the soft rubber sleeve 121 bends under the action of the first hinge piece 111 and the second hinge piece 112, wrapping and protecting the conductive wire 124, thus maintaining the electrical connection between the photovoltaic panels 200.

[0036] In one embodiment, a protective frame 21 is provided around the circumference of the photovoltaic panel 200. The protective frame 21 has an installation notch 211. A soft rubber sleeve 121 is inserted into the installation notch 211. A first hinge piece 111 and a second hinge piece 112 are connected to both ends of the installation notch 211 and cover it. The installation notch 211 provides a clear insertion position for the soft rubber sleeve 121. During the installation and assembly of the photovoltaic panel 200, the soft rubber sleeve 121 can be precisely inserted into the installation notch 211 of the protective frame 21 to prevent the soft rubber sleeve 121 from shifting during the folding or unfolding of the photovoltaic panel, thus avoiding unstable electrical connection between the photovoltaic panel 200 and the soft rubber sleeve 121. In other embodiments, the installation notch 211 may not be provided.

[0037] In one embodiment, the soft rubber sleeve 121 has a folding groove 122 on the side near the hinge body 11. Two folding grooves 122 are provided, respectively located near the edges of the protective frames 21 of the two photovoltaic panels 200. When the photovoltaic folding panel is folded, the soft rubber sleeve 121 bends under the clamping of the first hinge piece 111 and the second hinge piece 112. The folding groove 122 ensures that the soft rubber sleeve 121 bends at the location of the folding groove 122 during bending, and that the thickness of the soft rubber sleeve 121 after bending matches the gap between the two protective frames 21, reducing the influence of the soft rubber sleeve 121 on the rotation of the photovoltaic folding panel. In other embodiments, folding grooves may not be provided.

[0038] In one embodiment, the soft rubber sleeve 121 has a slot 123 on the side away from the hinge body 11. One sidewall of the slot 123 engages with the edge of the mounting notch 211 of a protective frame 21, and the opposite sidewall of the slot 123 engages with the edge of the call number mounting notch 211 of another protective frame 21. When the two photovoltaic panels 200 connected to the hinge body 11 rotate relative to each other to fold, the opposite sidewalls of the slot 123 move closer to each other under the influence of the mounting notch 211. This prevents the soft rubber sleeve 121 from coming out of the mounting notch 211 during the rotation of the photovoltaic panel 200. In other embodiments, the slot 123 may not be provided, and the soft rubber sleeve 121 is fixedly connected to the edge of the mounting notch 211 with adhesive.

[0039] In one embodiment, at least two connection pins 13 are provided within the mounting notch 211, and the connection pins 13 are electrically connected to the conductive wire 124. Further, the connection pin 13 includes a first bent segment 131, a second bent segment 132, and a third bent segment 133, which are sequentially bent. The first bent segment 131 and the third bent segment 133 extend within the mounting notch 211 toward another mounting notch 211. The second bent segment 132 extends in the thickness direction of the protective frame 21. The first bent segment 131 is connected to the photovoltaic panel 200, and the third bent segment 133 can extend into the soft rubber sleeve 121 and connect to the conductive wire 124 within the soft rubber sleeve 121. Specifically, the conductive wire 124 is soldered to the third bent segment 133. The bent structure of the connection pin 13 provides a certain degree of guidance during installation. The extending directions of the first bent segment 131 and the third bent segment 133 can guide the pin to be accurately inserted into the corresponding position within the mounting notch 211, reducing installation difficulty and improving installation efficiency. If it is necessary to replace the soft rubber sleeve 121 or repair the conductive wire 124, its bent portion can provide a certain amount of room for movement, facilitating tool or hand operation, making it easier to replace or maintain the components within the mounting notch 211. In other embodiments, the connecting pin 13 may be omitted, and the conductive wire 124 may extend out of the soft rubber sleeve 121 and be soldered to the positive and negative electrodes of the photovoltaic panel 200.

[0040] In one embodiment, the protective frame 21 is made of metal, and an insulating member 14 is provided inside the conductive hinge 100. The insulating member 14 is located between the connecting pin 13 and the side wall of the mounting notch 211 to prevent short circuits caused by the connecting pin 13 abutting against the protective frame 21. In other embodiments, the protective frame 21 may also be made of an insulating material such as plastic.

[0041] In one embodiment, the insulating member 14 is provided with an insulating partition 141, which is disposed between two adjacent connecting pins 13 to prevent short circuits caused by the two connecting pins 13 abutting against each other. In other embodiments, the insulating partition 141 may not be provided, and the connecting pins 13 may be provided with an insulating coating. When the conductive wire 124 is connected to the connecting pin 13, the insulating coating at the connection between the connecting pin 13 and the conductive wire 124 needs to be scraped off.

[0042] In one embodiment, the hinge body 11 further includes a first bushing assembly 15 and a second bushing assembly 16. Both the first bushing assembly 15 and the second bushing assembly 16 include two bushings respectively connected to the first hinge piece 111 and the second hinge piece 112, and a shaft passing through the bushings. A clearance gap 17 is provided between the first bushing assembly 15 and the second bushing assembly 16. When the soft rubber sleeve 121 is bent, the clearance gap 17 can prevent the soft rubber sleeve 121 from protruding from the protective frame 21. In other embodiments, the clearance gap 17 may not be provided, and the soft rubber sleeve 121 can slide towards the photovoltaic panel 200 within the mounting notch 211, allowing the photovoltaic folding panel to have a high degree of rotation.

[0043] This utility model also proposes a photovoltaic folding panel, which includes at least two photovoltaic panels 200 and a conductive hinge 100. The specific structure of the conductive hinge 100 is as described in the above embodiments. Since this photovoltaic folding panel adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. Adjacent photovoltaic panels 200 are rotatably connected and electrically connected through the conductive hinge 100.

[0044] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
