Description

Technical Field

[0001] This application relates to the field of solar charging, and in particular to a photovoltaic folding panel. Background Technology

[0002] With the escalation of the global energy crisis, the application of renewable energy, especially solar energy, is becoming more and more widespread. Traditional solar panels are usually fixed, occupy a lot of space, and are inconvenient to transport and install. In recent years, foldable solar panels have been favored by the market due to their lightweight and portable features.

[0003] In related technologies, there are two wiring methods for foldable solar panels. The first method involves setting a junction box on the metal frame of the panel. This wiring structure is simple and reliable, but it increases the volume and weight, affecting the folding of the panel. The second method involves embedding the wiring terminals inside the solar panel. This wiring structure reduces the number of external accessories and improves the compactness of the product, but it is more difficult to maintain in actual use, and the repair cost will be higher if the wiring is damaged. Utility Model Content

[0004] In order to maintain the structural simplicity of the folded panel and facilitate its maintenance, this application provides a photovoltaic folded panel.

[0005] The photovoltaic folding panel provided in this application adopts the following technical solution:

[0006] A photovoltaic folding panel, comprising:

[0007] Photovoltaic panels;

[0008] A frame is provided around the edge of the photovoltaic panel, and the frame is divided into a straight section and a corner section;

[0009] An output interface module is built into the corner, and the port of the output interface module is exposed.

[0010] The adjacent photovoltaic panels are hinged together, and each photovoltaic panel is equipped with a frame. The two frames that are furthest apart are provided with the output interface module on the corner of the side that is far away from each other.

[0011] The wiring structure between adjacent photovoltaic panels passes through the hinge between them.

[0012] By adopting the above technical solution, firstly, because the output interface module is located on the corner protector of the frame, the size and weight of the frame will not increase significantly while wiring is implemented. Furthermore, the wiring structure can be maintained by simply opening the corner, thus reducing the maintenance difficulty of the folding panel. Secondly, it not only allows photovoltaic folding panels to be connected to energy storage devices, but also allows multiple photovoltaic folding panels to be connected in parallel or in series. Thirdly, it makes the structure of the folding panel simpler, and the hinge allows the wiring structure between photovoltaic panels to bend smoothly during folding, thus facilitating the use of photovoltaic folding panels.

[0013] Preferably, the corner portion has a built-in folding magnet.

[0014] By adopting the above technical solution and using folding magnets, the folding plate can maintain its posture stability after being folded up.

[0015] Preferably, the corner portion has a structure in which two axisymmetric components are combined.

[0016] By adopting the above technical solution, it is easy to disassemble the corner parts and maintain the wiring structure between the output interface module and the photovoltaic panel.

[0017] Preferably, a hinge and a cable guard are provided between two adjacent photovoltaic panels. The two blades of the hinge are respectively connected to the two straight sections. The blades of the hinge are provided with a cable groove on the side closer to the straight section. The cable groove between the two blades is open on the side away from each other. The straight section is provided with a display window at the location of the hinge. The display window is connected to the cable groove. The two ends of the cable guard are embedded in the cable groove. The cable guard and the side of the hinge away from the straight section are provided for the wiring structure to be accommodated.

[0018] By adopting the above technical solution, compared with the method where the wiring structure needs to penetrate through the hinge blade, this design allows the wiring structure to extend from the inside to the outside along the hinge under the protection of the wire sleeve. Therefore, while fully protecting the wiring structure and maintaining the smooth unfolding and closing of the folding plate, it is easier to complete the connection between the wiring structure and the hinge.

[0019] Preferably, the straight section is made of metal, the corner section is made of plastic, and the corner section covers the end of the straight section.

[0020] By adopting the above technical solution, the straight section serves as the structure to keep the photovoltaic panel flat, while the corner sections can utilize the material and volume to allow the folded panel to be stably placed on the external plane.

[0021] Preferably, the photovoltaic panel is provided with a retractable support for tilting and supporting the photovoltaic panel.

[0022] By adopting the above technical solution, an angle can be formed between the sun-facing side of the photovoltaic panel and the horizontal plane, thereby allowing more sunlight to shine onto the photovoltaic panel.

[0023] Preferably, the retractable bracket includes a support frame and a belt-type tightening assembly. One side of the support frame is rotatably connected to the upper side of the frame to bring the support frame close to the large surface of the photovoltaic panel, and the other end is used to abut against the outer plane. The belt-type tightening assembly connects the support frame and the photovoltaic panel respectively to maintain a predetermined angle between the support frame and the photovoltaic panel.

[0024] By adopting the above technical solution and using the belt tightening component, the photovoltaic panel can have different angles with the horizontal plane to accommodate optical fibers at different times, and the structure of the photovoltaic folding panel can be kept compact after folding.

[0025] Preferably, there is a gap between the two photovoltaic panels on their adjacent sides; an electrical contact is provided at the position where the two frames are close to each other; a cooling box is magnetically attached to the side where the two frames are close to each other, the cooling box is located on the sun-facing side, the cooling box is electrically connected to the electrical contact, the cooling box contains a dry ice box and a cooling fan, the cooling box is provided with an air inlet and an air outlet, the air inlet is away from the sun-facing side, and the air outlet is located on the surface adjacent to the sun-facing side.

[0026] By adopting the above technical solution, a cooling box can be installed when using photovoltaic folding panels, allowing the cooling fan to be activated to introduce air from the back side. The air then passes through the dry ice box and flows out from the sun-facing side of the photovoltaic panel, thus dissipating heat from the photovoltaic panel and improving its photoelectric conversion efficiency.

[0027] Preferably, the corner portion is provided with a sealing cover at the port of the output interface module.

[0028] By adopting the above technical solution, when no wiring is required, the sealing cover can prevent dust from entering the output interface module from the port.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] 1. Because the output interface module is located on the corner protector of the frame, the size and weight of the frame will not increase significantly while wiring is implemented. Furthermore, the wiring structure can be maintained by simply opening the corner, thus reducing the maintenance difficulty of the folding plate.

[0031] 2. Compared to the wiring structure that needs to penetrate the hinge blade, this design allows the wiring structure to extend from the inside to the outside of the hinge under the protection of the cable sleeve. Therefore, while fully protecting the wiring structure and ensuring smooth opening and closing of the folding plate, it is easier to complete the connection between the wiring structure and the hinge.

[0039] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0040] This application discloses a photovoltaic folding panel.

[0041] Reference Figure 1 and Figure 2 The photovoltaic folding panel includes a photovoltaic panel 1, a frame 2, and an output interface module 3. The photovoltaic panel 1 is roughly in the shape of a cuboid thin plate; the frame 2 is roughly in the shape of a rectangular frame 2, which covers the edge of the photovoltaic panel 1 and is divided into a straight part 21 and a corner part 22; the output interface module 3 is built into the corner part 22 and the port of the output interface module 3 is exposed.

[0042] Reference Figure 1 and Figure 2 Because the output interface module 3 is located on the corner protector of the frame 2, the volume and weight of the frame 2 will not increase significantly while wiring is implemented. Furthermore, the wiring structure can be maintained by simply opening the corner 22, thereby reducing the maintenance difficulty of the folding plate. For example, during manufacturing, the corner 22 can be made by combining two axisymmetric elements, which also allows the corner 22 to be disassembled to expose the wiring structure between the output interface module 3 and the photovoltaic panel 1.

[0043] Reference Figure 1 and Figure 2 To improve the storage stability and placement stability of the folding panel, the following features are provided: First, the corner portion 22 has a built-in folding magnet 221 to prevent the folding panel from unfolding after it is folded, thereby maintaining the stability of the folding panel's posture. Second, the straight portion 21 is made of metal, usually aluminum, while the corner portion 22 is made of plastic. The corner portion 22 covers the end of the straight portion 21, so that the corner portion 22 has a larger volume and can also have friction heat, so that the folding panel can be placed stably on the external plane.

[0044] Reference Figure 2 and Figure 3 A photovoltaic folding panel requires at least two photovoltaic panels 1. In order to achieve folding, adjacent photovoltaic panels 1 are hinged together. The hinge structure is set on the frame 2. Therefore, one photovoltaic panel 1 is equipped with one frame 2. At the same time, in order to enable multiple photovoltaic folding panels to be connected in parallel or in series, output interface modules 3 are installed on the corners 22 of the two frames 2 that are furthest apart from each other.

[0045] In addition, in this embodiment, considering that when series or parallel connection is not required, in order to prevent dust from entering the output interface module 3, the corner portion 22 is provided with a sealing cover 222 at the port of the output interface module 3. The sealing cover 222 is made of elastic material. One end of the sealing cover 222 is clamped and fixed by the corner portion 22, and the remaining part can be sealed by interference fit to seal the port of the output interface module 3.

[0046] Reference Figure 4 and Figure 5To simplify the structure of the folding panel and ensure that the wiring between the photovoltaic panels 1 is not affected during folding (e.g., not broken by the two adjacent frame edges 2), the wiring between adjacent photovoltaic panels 1 passes through the hinge. Specifically, a hinge 4 and a cable guard 5 are provided between two adjacent photovoltaic panels 1. The two blades of the hinge 4 are connected to two straight sections 21 respectively. The blades of the hinge 4 have a cable groove 41 on the side closer to the straight section 21. The cable groove 41 between the two blades opens on the side away from each other. The straight section 21 has a display window 211 at the location of the hinge 4. The display window 211 is connected to the cable groove 41. The cable guard 5 is made of soft silicone material. Both ends of the cable guard 5 are embedded in the cable groove 41. The cable guard 5 and the side of the hinge 4 away from the straight section 21 are used to accommodate the wiring structure.

[0047] Reference Figure 4 and Figure 5 Under the protection of the cable sleeve 5, the wiring structure extends from the inside to the outside along the hinge 4. Therefore, while fully protecting the wiring structure and ensuring smooth opening and closing of the folding plate, it is easier to complete the connection between the wiring structure and the hinge 4.

[0048] Reference Figure 6 To fully utilize sunlight, the photovoltaic panel 1 is generally better positioned perpendicular to the direction of sunlight. However, to maintain the simplicity of the structure after storage, the photovoltaic panel 1 is equipped with a retractable support 6. The retractable support 6 is located on the back side of the photovoltaic panel 1 to support the photovoltaic panel 1 at an angle. Specifically, the retractable support 6 includes a support frame 61 and a belt-type tightening assembly 62. The support frame 61 is quadrilateral in shape, with one side of the support frame 61 rotatably connected to the upper side of the frame 2 so that the support frame 61 is close to the large surface of the photovoltaic panel 1, and the other end abuts against the outer plane. The belt-type tightening assembly 62 connects the support frame 61 and the photovoltaic panel 1 respectively, and applies a force close to the photovoltaic panel 1 to the support frame 61 by means of a belt loop, so that the support frame 61 and the photovoltaic panel 1 maintain a predetermined angle. At the same time, this belt-type tightening assembly 62 is also relatively small in size when stored.

[0049] The implementation principle of a photovoltaic folding panel in this application embodiment is as follows: Since the output interface module 3 is set on the corner protection part of the frame 2, the volume of the frame 2 will not increase significantly while realizing the wiring, and the weight will not increase significantly either. Furthermore, the wiring structure can be maintained by directly opening the corner part 22, thereby reducing the maintenance difficulty of the folding panel.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
