Traditional solar panels are usually fixed, occupy a large space, and are not convenient for transportation and installation. In recent years, foldable solar panels have been favored by the market because of their light weight and easy portability.

[0003] In the related art, there are two ways to connect foldable solar panels. The first is to set a junction box on the metal frame of the panel. This wiring structure is simple and reliable, but it adds extra volume and weight, affecting the folding of the panel. The second is to embed the wiring terminals into the interior of 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 once the line is damaged.

[0034] The following is combined with Figure 1-7 This application is described in further detail.

[0035] The embodiment of the present application discloses a photovoltaic folding panel.

[0036] 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 rectangular thin plate; the frame 2 is roughly in the shape of a rectangular frame 2, and the frame 2 is wrapped around the edge of the photovoltaic panel 1. The frame 2 is divided into a straight portion 21 and a corner portion 22; the output interface module 3 is built into the corner portion 22, and the port of the output interface module 3 is exposed.

[0037] Reference Figure 1 and Figure 2 Because the output interface module 3 is arranged on the corner guard of the frame 2, the volume of the frame 2 will not increase significantly while the wiring is realized, and the weight will not increase significantly either. The wiring structure can be maintained by directly opening the corner 22, thereby reducing the maintenance difficulty of the folding plate. For example, during manufacturing, the corner 22 can be made by merging two axially symmetrical elements.

[0038] Reference Figure 1 and Figure 2 In order to improve the storage stability of the folding board and the placement stability after unfolding, the following settings are correspondingly made: first, a folding magnet 221 is built into the corner portion 22 to prevent the folding board from being easily unfolded after the folding board is folded, thereby maintaining the posture stability of the folding board; second, the straight portion 21 is made of metal material, usually aluminum material, and the corner portion 22 is made of plastic material. The corner portion 22 covers the end of the straight portion 21, so that the volume of the corner portion 22 is relatively large, and the friction temperature can also be provided on the corner portion 22, so that the folding board can be stably placed on the external plane.

[0039] Reference Figure 2 and 3 The photovoltaic folding panel must have at least two photovoltaic panels 1. In order to achieve folding, adjacent photovoltaic panels 1 are hinged. The hinge structure will be set on the frame 2. The hinge structure is located on the backlight side of the photovoltaic panel. Therefore, one photovoltaic panel 1 is provided with a frame 2. At the same time, in order to allow multiple photovoltaic folding panels to be connected in parallel or in series, the two frames 2 that are farthest away will be installed with an output interface module 3 on the corners 22 on the side away from each other.

[0040] In addition, in the present embodiment, considering that when series or parallel connection is not required, in order to prevent dust from entering the output interface module 3, a sealing cover 222 is provided at the port of the output interface module 3 on the corner portion 22. The sealing cover 222 is made of an elastic material, and one end of the sealing cover 222 is clamped and fixed by the corner portion 22, and the remaining part can be sealed by an interference fit.

[0041] Reference Figure 4 and Figure 5 In order to make the structure of the folding plate more concise, and at the same time, in the folding process of the folding plate, in order to prevent the wiring structure between the photovoltaic panels 1 from being affected, such as being pinched off by two adjacent frames 2, the wiring structure between the adjacent photovoltaic panels 1 will pass through the hinge between the two. Specifically, a hinge 4 and a wire sheath 5 are arranged between the two adjacent photovoltaic panels 1, and the two blades of the hinge 4 are respectively connected to the two straight portions 21. The blades of the hinge 4 are provided with a wire accommodating groove 41 on the side close to the straight portion 21, and the wire accommodating groove 41 between the two blades is opened on the side away from each other. The straight portion 21 is provided with a display board window 211 at the position where the hinge 4 is located, and the display board window 211 is connected to the wire accommodating groove 41. The wire sheath 5 is made of soft silicone material, and both ends of the wire sheath 5 are embedded in the wire accommodating groove 41, and the wiring structure is accommodated between the wire sheath 5 and the side of the hinge 4 away from the straight portion 21.

[0042] Reference Figure 4 and Figure 5Under the action of the wire protection sleeve 5, the wiring structure is extended from the inside to the outside along the hinge 4, so while fully protecting the wiring structure and keeping the folding plate unfolding and closing smoothly, it is easier to complete the matching connection between the wiring structure and the hinge 4.

[0043] Reference Figure 6 In order to make full use of the light, the photovoltaic panel 1 is usually perpendicular to the direction of light. But at the same time, in order to maintain the simplicity of the structure after storage, the photovoltaic panel 1 is provided with a retractable bracket 6, which is located on the backlight side of the photovoltaic panel 1 to support the photovoltaic panel 1 in an inclined manner. Specifically, the retractable bracket 6 includes a support frame 61 and a belt-type tightening assembly 62. The support frame 61 is in the shape of a quadrilateral frame. One side of the support frame 61 is rotatably connected to the upper side of the frame 2 so that the support frame 61 is close to or the large surface of the photovoltaic panel 1, and the other end will abut against the external plane. The belt-type tightening assembly 62 is respectively connected to the support frame 61 and the photovoltaic panel 1, so as to apply a force to the support frame 61 to approach the photovoltaic panel 1 by means of a belt winding ring, so that the support frame 61 and the photovoltaic panel 1 maintain a predetermined angle. At the same time, the volume of this belt-type tightening assembly 62 is relatively small in the storage state.

[0044] Reference Figure 7 In order to dissipate heat for the photovoltaic panel 1, there is a gap between the sides of the two photovoltaic panels 1 that are close to each other, and at the same time, an electrical contact 7 is provided at the position where the two frames 2 are close to each other. A cooling box 8 is magnetically provided on the side of the two frames 2 that are close to each other, and the cooling box 8 is located on the sunny side. The cooling box 8 is electrically connected to the electrical contact 7. The cooling box 8 has a dry ice box 81 and a heat dissipation fan 82 built in. The cooling box 8 is provided with an air inlet 83 and an air outlet 84. The air inlet 83 is away from the sunny side, and the air inlet 83 is connected to the gap between the two frames 2. The air outlet 84 is located on the surface adjacent to the sunny side. When the photovoltaic folding panel is in use, the cooling box 8 can be installed, and the heat dissipation fan 82 can be started to introduce air from the backlight side, and the air passes through the dry ice box 81 and then flows out from the sunny side of the photovoltaic panel 1, so that the photovoltaic panel 1 can be cooled, thereby improving the photoelectric conversion efficiency of the photovoltaic panel 1.

[0045] The implementation principle of a photovoltaic folding panel in an embodiment of the present application is as follows: since the output interface module 3 is arranged on the corner guard portion of the frame 2, the volume of the frame 2 will not increase significantly while wiring is being realized, and the weight will not increase significantly either, and the wiring structure can be maintained by directly opening the corner portion 22, thereby reducing the difficulty of maintaining the folding panel.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
