Description

Technical Field

[0001] The present application relates to the field of solar energy technology, and in particular to a portable solar panel. Background Art

[0002] The portable solar panel has multiple panels that can be stacked when stored and unfolded when used, and also has a support mechanism to support the panels when used. However, in the related art, the supporting mechanism and the panel have a relatively complex structure, and usually protrude significantly from the panel, which increases the thickness of the solar panel and occupies a larger space when stored. Utility Model Content

[0003] In view of this, the present application provides a portable solar panel that can achieve the integration of its support and sub-panel without affecting the sub-panel structure, thereby reducing the overall thickness and saving the space required for storage and transportation.

[0004] One embodiment of the present application provides a portable solar panel. The portable solar panel includes a sub-panel and a support member. Two adjacent sub-panels are foldably connected. The support member is connected to the folding connection of the two adjacent sub-panels and is configured to be able to rotate to a supporting position and a storage position. When the support member is rotated to the supporting position, a supporting angle is formed relative to the sub-panel. When the support member is rotated to the storage position, it is hidden in the gap between the two adjacent sub-panels, so that the portable solar panel is roughly plate-shaped.

[0005] In the above embodiment, after the two adjacent sub-boards are relatively unfolded, the support member can be rotated and switched between the support position and the storage position. When the support member is in the support position, a certain support angle is formed between the support member and the sub-board, so that the support member can be supported between the sub-board and the ground, and the sub-board is maintained in a tilted posture relative to the ground, so that the portable solar panel can work. And by connecting the support member to the folding connection of the two adjacent sub-boards, the support member can be rotated to hide between the two adjacent sub-boards when in the storage position, thereby avoiding the support member directly increasing the thickness on the basis of the sub-board. And the folding connection is usually for the convenience of folding, and can have a certain gap compared to the flat structure of the sub-board, so that at least part of the structure of the support member is sunk under the surface of the two adjacent sub-boards, so as to reduce the overall thickness of the portable solar panel, which is conducive to saving the space required for storage and transportation.

[0006] In some embodiments of the present application, the portable solar panel further comprises a connector. Each two adjacent sub-panels are connected by a connector. The connector is configured to be able to bend so that the multiple sub-panels can be folded. The support member is rotatably connected to the connector so as to be able to rotate to a supporting position or a storage position.

[0007] In the above embodiment, two adjacent sub-panels are folded by a connecting member so as to provide a larger gap between the two sub-panels, and the supporting member is rotatably connected to the connecting member so that the supporting member can be hidden in the gap between the two adjacent sub-panels when in the storage position, thereby helping to reduce the overall thickness of the portable solar panel.

[0008] In some embodiments of the present application, the connecting member is a flexible member and is constructed to be able to withstand external force to generate elastic deformation.

[0009] In the above embodiment, when two adjacent sub-panels switch between the unfolded state and the folded state, the relative positions of the two and the support member will change, and the relative position of the connecting member and the support member will also change. By configuring a flexible connecting member, when the support member rotates to the storage position, even if the relative positions of the two adjacent sub-panels or the connecting member and the support member change, the support member can compress the connecting member to cause the connecting member to produce elastic deformation, thereby maintaining the support member in the storage position, which is beneficial to reduce the structural size of the connecting member while still allowing the supporting member to be hidden between the two adjacent sub-panels, thereby further reducing the overall thickness of the portable solar panel.

[0010] In some embodiments of the present application, the support member includes a soft portion and a hard portion. The soft portion and the connecting member are an integral piece. The hard portion is connected to the soft portion. The hard portion extends in a direction perpendicular to the rotation axis of the support member.

[0011] In the above embodiment, by integrating a part of the support member with the connecting member, on the one hand, the support member can realize rotation relative to the connecting member through elastic deformation of the flexible soft part or the flexible connecting member, and on the other hand, the connecting member and the support member can be manufactured at the same time to simplify the production process. In addition, the hard part is connected to the soft part, so that after the support member rotates to the supporting position, the support member can support the sub-board through the rigid structure of the hard part.

[0012] In some embodiments of the present application, the soft part is wrapped in the hard part.

[0013] In the above embodiment, no matter where the support member rotates to, the soft part can be blocked between the hard part and the sub-board, which helps to prevent the hard part from scratching or damaging the sub-board and also helps to reduce the harm to the user caused by the hard part.

[0014] In some embodiments of the present application, the connecting member is provided with a groove or a through opening. When the supporting member rotates to the supporting position, at least a portion of the supporting member is accommodated in the opening or the groove.

[0015] In the above embodiment, by accommodating at least part of the support member in the opening or groove, the height of the support member relative to the surface of the sub-board is further reduced when two adjacent sub-boards are unfolded, thereby reducing the overall thickness. At the same time, when two adjacent sub-boards are folded, the support member reduces the obstruction to the relative rotation of the two sub-boards.

[0016] In some embodiments of the present application, a partial connecting member exists between the supporting member and at least one of two adjacent sub-boards.

[0017] In the above embodiment, when two adjacent sub-panels are folded, the support member can rotate relative to at least one side of the sub-panel, thereby reducing the interference of the support member on the rotation of the sub-panel, so as to increase the rotation angle of the two adjacent sub-panels when folded relative to the unfolding, which is beneficial to reduce the overall thickness of the portable solar panel after it is folded.

[0018] In some embodiments of the present application, the support member has a rotating end. The folding connection between two adjacent sub-plates has a rotating mating end. The rotating end is rotatably connected to the rotating mating end. The rotating mating end and / or the rotating end are provided with a damping structure to increase the damping of the rotation of the support member relative to the folding connection between the two adjacent sub-plates.

[0019] In the above embodiment, the rotating end and the rotating mating end are rotationally connected via a damping structure, which facilitates the rotating end and the rotating mating end to rotate and stay at multiple different angles, thereby allowing the support member to form multiple supporting angles relative to the sub-board, increasing user convenience.

[0020] In some embodiments of the present application, the support member has a rotating end, and a first quick-release structure is provided on the rotating end, and the rotating end is rotatably connected to the folding connection of two adjacent sub-plates through the first quick-release structure.

[0021] In the above embodiment, by providing the first quick-release structure, it is convenient to disassemble and assemble the support member relative to the sub-board, thereby facilitating the replacement or maintenance of the support member. In addition, the overall thickness of the portable solar panel can be further reduced by disassembling the support member.

[0022] In some embodiments of the present application, the support member has a free end. The free end is configured to be supported in an external environment. The free end is provided with a second quick-release structure. When the support member is rotated to the storage position, the free end is configured to be connected to the folding connection of two adjacent sub-plates through the second quick-release structure.

[0023] In the above embodiment, by providing a second quick-release structure, the free end of the support member can be fixed relative to the sub-board when the support member is rotated to the storage position. Then, under the constraints of multiple structures, the support member can be fixed at the storage position relative to the sub-board, which is convenient for the storage and transportation of the portable solar panel.

[0024] In some embodiments of the present application, the free end is further provided with a bending portion and a quick release fitting portion. Along the extension direction of the support member, the bending portion is located between the second quick release structure and the quick release fitting portion. The bending portion is configured to be deformable to flip the second quick release structure, so that the folded connection or quick release fitting portion of two adjacent sub-plates is respectively connected to the second quick release structure.

[0025] In the above embodiment, when the support member rotates to the supporting position, the second quick-release structure can be flipped to be fixed with the quick-release mating portion. When the support member supports the sub-plate, on the one hand, it is convenient to reduce the interference of the second quick-release structure with the supporting contact between the free end and the external environment. On the other hand, it is convenient to store and protect the second quick-release structure so that the second quick-release structure is relatively fixedly connected to the folded connection between the two adjacent sub-plates.

[0039] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0041] As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0042] Furthermore, the terms “first”, “second”, etc. are used for descriptive purposes only and are not to be understood as indicating or implying relative importance.

[0043] The portable solar panel has multiple panels that can be stacked when stored and unfolded when used, and also has a support mechanism to support the panels when used. However, in the related art, the supporting mechanism and the panel have a relatively complex structure, and usually protrude significantly from the panel, which increases the thickness of the solar panel and occupies a larger space when stored.

[0044] An embodiment of the present application provides a portable solar panel. The portable solar panel includes a sub-panel and a support member. Two adjacent sub-panels are foldably connected. The support member is connected to the folding connection of the two adjacent sub-panels and is configured to be able to rotate to a supporting position and a storage position. When the support member is rotated to the supporting position, a supporting angle is formed relative to the sub-panel. When the support member is rotated to the storage position, it is hidden in the gap between the two adjacent sub-panels, so that the portable solar panel is roughly plate-shaped.

[0045] After the two adjacent sub-panels are relatively unfolded, the support member can be rotated and switched between the support position and the storage position. When the support member is in the support position, a certain support angle is formed between the support member and the sub-panel, so that the support member can be supported between the sub-panel and the ground, and the sub-panel is maintained in a tilted posture relative to the ground, so that the portable solar panel can work. And by connecting the support member to the folding connection of the two adjacent sub-panels, the support member can be rotated to hide between the two adjacent sub-panels when in the storage position, thereby avoiding the support member directly increasing the thickness on the basis of the sub-panel. And the folding connection is usually for the convenience of folding, and can have a certain gap compared to the flat structure of the sub-panel, so that at least part of the structure of the support member is sunk under the surface of the two adjacent sub-panels, so as to reduce the overall thickness of the portable solar panel, which is conducive to saving the space required for storage and transportation.

[0046] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0047] See also Figure 1 , one embodiment of the present application provides a portable solar panel 100. The portable solar panel 100 is capable of converting light energy into electrical energy. In some embodiments, the portable solar panel 100 outputs direct current to the outside, and can directly supply power to electrical equipment that can be powered by direct current; or, the portable solar panel 100 can supply power to electrical equipment that can be powered by alternating current through an external inverter module. In some embodiments, the portable solar panel 100 has a built-in battery for storing electricity, thereby storing a certain amount of electrical energy; or the portable solar panel 100 can omit the built-in battery and store electricity through an external energy storage power supply or other device that can store electrical energy.

[0048] See also Figure 1 and Figure 2 In some embodiments, the portable solar panel 100 includes a sub-panel 10. Two or more sub-panels 10 are provided. Two adjacent sub-panels 10 can be folded and connected for easy storage and transportation. Figure 1 and Figure 2 All of them are in the unfolded state of the portable solar panel 100, and the present application omits the structural schematic diagrams of the portable solar panel 100 after the sub-panels 10 are folded.

[0049] See also Figure 1 and Figure 2 In some embodiments, at least part of the sub-panel 10 includes a substrate 11 and a photovoltaic module 12. The photovoltaic module 12 is disposed on the outer surface of the substrate 11.

[0050] See also Figures 1 to 3In some embodiments, the portable solar panel 100 further includes a support member 20. The support member 20 is connected to the folding connection of two adjacent sub-panels 10, and is configured to be able to rotate to a supporting position and a storage position. When the support member 20 is rotated to the supporting position, a supporting angle is formed relative to the sub-panel 10. When the support member 20 is rotated to the storage position, it is hidden in the gap between the two adjacent sub-panels 10, so that the portable solar panel 100 is roughly plate-shaped. The support angle is the angle α between the support member 20 and the sub-panel 10 when the support member 20 props up the sub-panel 10 relative to the external environment (such as the ground).

[0051] After the two adjacent sub-panels 10 are relatively unfolded, the support member 20 can be rotated and switched between the supporting position and the storage position. When the support member 20 is in the supporting position, a certain support angle is formed between the support member 20 and the sub-panel 10, so that the support member 20 can be supported between the sub-panel 10 and the ground, and the sub-panel 10 is maintained in a tilted posture relative to the ground, so that the portable solar panel 100 can work. And by connecting the support member 20 to the folding connection of the two adjacent sub-panels 10, the support member 20 can be rotated to hide between the two adjacent sub-panels 10 when in the storage position, thereby avoiding the support member 20 directly increasing the thickness on the basis of the sub-panel 10. And the folding connection is usually convenient for folding, and a certain gap can be provided compared to the flat structure of the sub-panel 10, so that at least part of the structure of the support member 20 is sunk under the surface of the two adjacent sub-panels 10, so as to reduce the overall thickness of the portable solar panel 100, which is conducive to saving the space required for storage and transportation.

[0052] In some embodiments, the thickness of each sub-panel 10 is thinner than the overall structure, so when the portable solar panel 100 is unfolded, the undulating structure of the sub-panel 10 surface can be ignored, so that the multiple sub-panels 10 are roughly plate-shaped. Among them, roughly plate-shaped means that after the multiple sub-panels 10 are unfolded, the relative position of each sub-panel 10 can be moved to be approximately a flat plate, which does not mean that it is completely flat, nor does it mean that the multiple sub-panels 10 can only be approximately a flat plate after unfolding. The multiple sub-panels 10 can also be distributed in an arc surface.

[0053] In some embodiments, the support angle is 30 degrees to 120 degrees to improve the stability of the supporting sub-board 10. In other embodiments, the support angle can be relaxed to a range of 0 degrees to 180 degrees.

[0054] See also Figure 1 and Figure 2 In some embodiments, the portable solar panel 100 further includes a connector 30. Each two adjacent sub-panels 10 are connected by a connector 30. The connector 30 is configured to be bendable so that the multiple sub-panels 10 can be folded. The support member 20 is rotatably connected to the connector 30 so as to be able to rotate to a supporting position or a storage position.

[0055] Two adjacent sub-panels 10 are folded by the connecting member 30 so as to have a larger gap between the two sub-panels 10, and the supporting member 20 is rotatably connected to the connecting member 30 so that the supporting member 20 can be hidden in the gap between the two adjacent sub-panels 10 when in the storage position, thereby helping to reduce the overall thickness of the portable solar panel 100.

[0056] In other embodiments, the connector 30 may be omitted. At least one of the two adjacent sub-boards 10 may be provided with a groove or a notch at the junction with the other sub-board, so as to form a gap for hiding the support member 20 .

[0057] See also Figure 1 and Figure 2 In some embodiments, after the portable solar panel 100 is unfolded, two adjacent sub-panels 10 are arranged at intervals, and the connecting member 30 is arranged between the two adjacent sub-panels 10. Thus, the gap between the two adjacent sub-panels 10 is increased, which facilitates hiding the supporting member 20.

[0058] In some embodiments, the connecting member 30 is a flexible member and is configured to be able to withstand external force to generate elastic deformation.

[0059] When two adjacent sub-panels 10 switch between the unfolded state and the folded state, the relative positions of the two and the support member 20 will change, and the relative position of the connector 30 and the support member 20 will also change. By configuring the flexible connector 30, when the support member 20 rotates to the storage position, even if the relative positions of the two adjacent sub-panels 10 or the connector 30 and the support member 20 change, the support member 20 can compress the connector 30 to cause the connector 30 to produce elastic deformation, so that the support member 20 is maintained in the storage position, which is conducive to reducing the structural size of the connector 30 while still allowing the support member 20 to be hidden between the two adjacent sub-panels 10, thereby further reducing the overall thickness of the portable solar panel 100.

[0060] In some embodiments, a flexible member is wrapped around the periphery of the substrate 11. Preferably, the flexible member wrapped around the periphery of the substrate 11 is made of the same material as the flexible member of the connector 30 and can be an integrally formed structure for ease of production and manufacturing.

[0061] It is understood that in some embodiments, when the connecting member 30 is a flexible member, its material can be rubber, cloth, soft plastic, etc., which can be elastically deformed. Among them, soft plastic includes but is not limited to TPE (Thermoplast ic Elastomer), TPU (Thermoplastic Urethane), soft PVC (Polyvinyl chloride), etc.

[0062] See also Figures 2 to 4 In some embodiments, the support member 20 includes a soft portion 21 and a hard portion 22. The soft portion 21 and the connecting member 30 are integrally formed. The hard portion 22 is connected to the soft portion 21. The hard portion 22 extends in a direction perpendicular to the rotation axis of the support member 20.

[0063] By integrating a part of the support member 20 with the connector 30, on the one hand, the support member 20 can be rotated relative to the connector 30 through the elastic deformation of the flexible soft part 21 or the flexible connector 30, and on the other hand, the connector 30 and the support member 20 can be manufactured at the same time to simplify the production process and save manufacturing materials. In addition, the hard part 22 is connected to the soft part 21, so that after the support member 20 rotates to the supporting position, the support member 20 can support the sub-board 10 through the rigid structure of the hard part 22. The support member can support and store through a simple structure through the cooperation of the soft part and the hard part, which is conducive to simplifying the structure of the support member, thereby reducing production costs and making the support member lightweight.

[0064] In other embodiments, the connecting member 30 and the supporting member 20 may be provided separately and rotatably connected via a rotating shaft or a ball shaft.

[0065] It is understandable that in some embodiments, the material of the hard part 22 is a material that can achieve rigid support, such as metal, ceramic, hard plastic, etc. Among them, hard plastic includes but is not limited to PMMA (Polymethyl Methacryl ate), PC (Polycarbonate), POM (Polyoxymethyl ene or Polyformaldehyde), PP (polypropyl ene), PE (Polyethyl ene), etc. The material of the soft part 21 is a material that can be elastically deformed, such as rubber, cloth, soft plastic, etc. Among them, soft plastic includes but is not limited to TPE, TPU, soft PVC, etc.

[0066] It can be understood that in some embodiments, the soft part 21 and the connecting member 30 are an integral part. Specifically, the soft part 21 and the connecting member 30 are an integrally formed structure. The two are integrally formed and prepared and the integral part is separated into two parts by cutting or trimming. Some of the two parts are separated at the boundary, while some of the boundaries remain connected, so that the soft part 21 is separated on the basis of the connecting member 30, so that the soft part 21 can move relative to the connecting member 30 and maintain the connection with the connecting member 30. By making the soft part 21 and the connecting member 30 an integral structure, the soft part 21 is connected to the hard part 22, and a simple process can be used to realize the production and mobility of the support member 20, the process is simple, the structure is simplified, and it is conducive to achieving lightweight portable solar panel 100.

[0067] It is understandable that in some embodiments, the soft part 21 and the hard part 22 can be connected by gluing, adding fasteners (screws, etc.), magnetic adsorption, etc., or the soft part 21 can be fixed to the hard part 22 by hot pressing, etc.

[0068] See also Figure 1 , Figure 3 and Figure 4 In some embodiments, the hard portion 22 is shaped like a column or a sheet, so that the support member 20 is shaped like a column or a sheet as a whole, thereby reducing the occupied space while supporting the sub-board 10 so as to be hidden in the gap between two adjacent sub-boards 10.

[0069] See also Figure 2 and Figure 4 In some embodiments, the soft part 21 is wrapped around the hard part 22. No matter where the support member 20 rotates, the soft part 21 can be blocked between the hard part 22 and the sub-board 10, which is beneficial to avoid or reduce the hard part 22 scratching or damaging the sub-board 10, and is also beneficial to avoid or reduce the user from being hurt by the hard part 22. As an illustrative example, the soft part 21 can be directly hot-pressed on the outer surface of the hard part 22, thereby wrapping the hard part 22. The soft part 21 wraps the hard part 22 by hot pressing, which has a simple structure and a simple molding process, can reduce costs, simplify the structure, and is beneficial to achieve lightweight portable solar panel 100.

[0070] See also Figure 1 and Figure 2 In some embodiments, the connecting member 30 is provided with a groove (not shown) or a through opening 31. When the supporting member 20 rotates to the supporting position, at least a portion of the supporting member 20 is accommodated in the opening 31 or the groove. It can be understood that in some embodiments, the through direction of the opening 31 is perpendicular to the extending direction of the axis of rotation of the supporting member 20.

[0071] By accommodating at least part of the support member 20 in the opening 31 or the groove, the height of the support member 20 relative to the surface of the sub-board 10 is further reduced when two adjacent sub-boards 10 are unfolded, thereby reducing the overall thickness. At the same time, when two adjacent sub-boards 10 are folded, the support member 20 reduces the obstruction to the relative rotation of the two sub-boards 10.

[0072] See also Figure 1 and Figure 2 In some embodiments, a partial connecting member 30 exists between the supporting member 20 and at least one of two adjacent sub-boards 10 .

[0073] When two adjacent sub-panels 10 are folded, the support member 20 can rotate relative to at least one side of the sub-panel 10, thereby reducing the interference of the support member 20 on the rotation of the sub-panel 10, so as to increase the rotation angle of the two adjacent sub-panels 10 when folded relative to the unfolding, which is beneficial to reducing the overall thickness of the portable solar panel 100 after being folded.

[0074] See also Figure 1 and Figure 2 In some embodiments, there are partial connectors 30 between two adjacent sub-panels 10 and the support members 20, respectively, so that the support members 20 can rotate relative to the sub-panels 10 on both sides, which is convenient for folding the two adjacent sub-panels 10. And after the two adjacent sub-panels 10 are folded, the support members 20 can be located on the same side of the two adjacent sub-panels 10, so that the thickness of the two adjacent sub-panels 10 can be used to accommodate the support members 20, which is conducive to reducing the overall thickness of the portable solar panel 100 after folding.

[0075] See also Figure 1 and Figure 2 In some embodiments, the support member 20 has a rotating end 23. The rotating end 23 is rotatably connected to the folded connection of two adjacent sub-boards 10. In some embodiments, the support member 20 has a free end 24. The free end 24 is configured to be supported in an external environment. In some embodiments, the rotating end 23 and the free end 24 are respectively two ends of the extension direction of the support member 20. The support member 20 extends in a direction perpendicular to the distribution direction of the two adjacent sub-boards 10.

[0076] See also Figure 1 and Figure 2 In some embodiments, the folded connection between two adjacent sub-boards 10 has a rotational mating end 32. The rotational end 23 is rotationally connected to the rotational mating end 32. The rotational mating end 32 and / or the rotational end 23 are provided with a damping structure (not shown) to increase the damping of the rotation of the support member 20 relative to the folded connection between the two adjacent sub-boards 10. It can be understood that in some embodiments, the connecting member 30 is provided with a rotational mating end 32.

[0077] The rotating end 23 and the rotating mating end 32 are rotationally connected via a damping structure, so that the rotating end 23 and the rotating mating end 32 can rotate and stay at multiple different angles (for example, 30 degrees, 45 degrees, 60 degrees, 75 degrees, 90 degrees, 105 degrees, 120 degrees or stepless changes, etc.), thereby allowing the support member 20 to form multiple support angles relative to the sub-board 10, thereby increasing user convenience.

[0078] It can be understood that in some embodiments, one of the rotational mating end 32 or the rotational end 23 is provided with a damping structure, or the rotational mating end 32 and the rotational end 23 cooperate to form a damping structure.

[0079] As illustrative examples, the damping structure includes but is not limited to a damping shaft, a gooseneck tube, a bellows, or a metal part that can be bent and deformed.

[0080] See also Figure 1 and Figure 2 In some embodiments, the rotating end 23 is provided with a first quick-release structure (not shown). The rotating end 23 is rotatably connected to the folded connection of two adjacent sub-plates 10 through the first quick-release structure. It can be understood that in some embodiments, the first quick-release structure is connected to the rotating mating end 32 of the connecting member 30.

[0081] By providing the first quick-release structure, it is convenient to disassemble and assemble the support member 20 relative to the sub-board 10, thereby facilitating the replacement or maintenance of the support member 20. In addition, the overall thickness of the portable solar panel 100 can be further reduced by disassembling the support member 20.

[0082] It can be understood that in some embodiments, the first quick-release structure is connected to the rotating mating end 32 by a buckle form, and the rotating end 23 is plugged and engaged with the rotating mating end 32, and the connection is fastened, and it is convenient to directly manufacture and shape it through a mold; or the first quick-release structure is connected to the rotating mating end 32 by a button form or a nylon buckle (also called Velcro), which has a simple structure and convenient connection, and the button overlap and nylon buckle bonding structure can be deformed to facilitate the rotation of the support member 20;

[0083] Alternatively, the first quick-release structure is connected to the rotating mating end 32 by magnetic adsorption. The magnetic adsorption structure can be easily hidden inside the rotating end 23 or the rotating mating end 32, and has a good protection effect, which is beneficial to improving the service life. Alternatively, the first quick-release structure is connected by clamping with a clamp, which is convenient for disassembly and assembly, and the connection is stable. The clamp can be replaced separately, which is easy to maintain.

[0084] See also Figure 1 , Figure 3 and Figure 4In some embodiments, the free end 24 is provided with a second quick-release structure 241. When the support member 20 is rotated to the storage position, the free end 24 is configured to be connected to the folded connection of two adjacent sub-boards 10 through the second quick-release structure 241.

[0085] By providing a second quick-release structure 241, the free end 24 of the support member 20 can be fixed relative to the sub-panel 10 when the support member 20 is rotated to the storage position. Under the constraints of multiple structures such as the rotating end 23 and the free end 24, the support member 20 can be fixed at the storage position relative to the sub-panel 10, which is convenient for storage and transportation of the portable solar panel 100.

[0086] See also Figure 1 and Figure 5 In some embodiments, the free end 24 is further provided with a bending portion 242 and a quick release fitting portion 243. Along the extension direction of the support member 20, the bending portion 242 is located between the second quick release structure 241 and the quick release fitting portion 243. The bending portion 242 is configured to be deformable to flip the second quick release structure 241, so that the folded connection or the quick release fitting portion 243 of two adjacent sub-plates 10 are respectively connected to the second quick release structure 241.

[0087] When the support member 20 rotates to the supporting position, the second quick-release structure 241 can be flipped to be fixed with the quick-release fitting portion 243. When the support member 20 supports the sub-plate 10, on the one hand, it is convenient to reduce the interference of the second quick-release structure 241 with the supporting contact and fit between the free end 24 and the external environment. On the other hand, it is convenient to store and protect the second quick-release structure 241, so that the second quick-release structure 241 is relatively fixedly connected to the folded connection between the two adjacent sub-plates 10.

[0088] It can be understood that in some embodiments, the second quick-release structure 241 is connected to the rotating mating end 32 or the quick-release mating part 243 by means of a snap-fit, and the rotating end 23 is plugged and engaged with the rotating mating end 32 or the quick-release mating part 243, and the connection is tight, and it is convenient to directly manufacture and shape it through a mold; or the second quick-release structure 241 is connected to the rotating mating end 32 or the quick-release mating part 243 by means of a button or a nylon buckle (also called Velcro), which has a simple structure and is convenient to connect, and the button overlap and nylon buckle bonding structure can be deformed to facilitate the rotation of the support member 20; or the second quick-release structure 241 is connected to the rotating mating end 32 or the quick-release mating part 243 by means of a magnetic adsorption, and the magnetic adsorption structure is easy to hide in the interior of the rotating end 23 or the rotating mating end 32 or the quick-release mating part 243, and has a good protection effect, which is beneficial to improving the service life; or the second quick-release structure 241 is connected by means of a clamp clamping, which is convenient for disassembly and assembly, and the connection is stable, and the clamp can be replaced separately, which is convenient for maintenance.

[0089] See also Figure 1 and Figure 2In some embodiments, the use principle of the portable solar panel 100 is that when the portable solar panel 100 is stored and transported, the support member 20 is rotated to the storage position, and the second quick-release structure 241 of the support member 20 is fixed to the connecting member 30, and multiple sub-panels 10 are unfolded or folded as needed; when the portable solar panel 100 performs photoelectric conversion, multiple sub-panels 10 are unfolded, the support member 20 is rotated to the supporting position, and the second quick-release structure 241 of the support member 20 is fixed to the quick-release mating part 243 of the support member 20 as needed.

[0090] In the present application, the portable solar panel 100 hides the support member 20 in the gap between two adjacent sub-panels 10 so that the support member 20 and the sub-panels 10 are integrated, thereby reducing the overall thickness and saving the space required for storage and transportation.

[0091] In the present application, the two being relatively perpendicular does not mean an absolute 90° relationship, but a certain deviation is allowed as long as it does not hinder the rotation of the support member 20 or the folding of the sub-plate 10.

[0092] In addition, those skilled in the art should recognize that the above embodiments are only used to illustrate the present application and are not intended to be limiting of the present application. As long as they are within the spirit and scope of the present application, appropriate changes and modifications to the above embodiments are within the scope of the present application.
