Technical Field
[0001] This application belongs to the field of solar energy equipment technology, and more specifically, relates to a portable foldable solar panel based on a quick-release hinge. Background Technology
[0002] With the continuous development of solar energy technology, solar panels are being used more and more widely in various fields, especially in terms of the increasing demand for portable solar panels. However, the portable solar panels commonly found on the market today use a design where flexible solar cells are directly glued onto a soft substrate, making it difficult to balance portability and structural rigidity in traditional folding solar panels. Although some solar panels are rigid, several small rigid solar panels are usually connected by simple hinges or fabric strips. Traditional hinge connections are inconvenient to install and disassemble and are cumbersome to operate, making it very inconvenient to quickly connect, lock, and separate solar panel units.

[0004] To achieve the above objectives, the technical solution adopted in this application is: to provide a portable foldable solar panel based on a quick-release hinge, comprising:
[0005] A solar panel unit, flat in shape, includes a frame and a solar panel, the solar panel being installed within a frame formed by multiple frames connected end-to-end; and...
[0006] A quick-release hinge connects two adjacent solar panel units. The quick-release hinge includes a male connector and a female connector. The male connector includes a male connector member, a locking pin, an integrated pivot, a resilient locking element, and a lever. The female connector includes a female connector member and a locking engagement part. The female connector member connects to one side of a solar panel unit. A locking groove and a locking engagement part are formed on the outer edge of the female connector member facing the other solar panel unit, and a pin hole is formed on the locking engagement part. The male connector member connects to the corresponding side of another adjacent solar panel unit. An integrated pivot is provided on the outer edge of the male connector member facing the female connector. The locking pin and the resilient locking element are built into the axially hollow integrated pivot, and the resilient locking element is sleeved on the inner end of the locking pin. The lever is connected to the locking pin.
[0007] The quick-release hinge has a locked state and an open state. In the locked state, the integrated pivot is housed in the locking groove, and the elastic locking element elastically abuts against the locking pin, so that the outer end of the locking pin extends out of the integrated pivot and is inserted into the pin hole, and the male and female components are connected and locked. In the open state, the lever moves the locking pin, the elastic locking element is compressed, the locking pin retracts to disengage from the pin hole, and the male and female components are separated.
[0008] Optionally, the first frame is connected to the female connector assembly, and the second frame is connected to the male connector assembly. Both the first and second frames include adjacent outer and inner sides. The female connector includes an integrally connected first and second connecting plates. The first connecting plate is attached to and fixedly connected to the outer side of the first frame, and the second connecting plate is attached to the inner side of the first frame. A locking groove and a locking mating part are formed on the outer edge of the second connecting plate away from the first connecting plate.
[0009] The male connector includes an integrally connected third connecting plate and a fourth connecting plate. The third connecting plate is attached to and fixedly connected to the outer side of the second frame, and the fourth connecting plate is attached to the inner side of the second frame.

[0013] Optionally, the integrated shaft is provided with an elongated hole extending axially, and the end of the lever connected to the locking pin can be moved back and forth within the elongated hole.
[0014] Optionally, a limiting part is also formed at the outer edge of the fourth connecting plate. The limiting part is located next to the integrated rotating shaft. In the locked state, the limiting part and the locking mating part limit and abut against each other.
[0015] Optionally, the locking mating part and the second connecting plate are integrally formed, and the integrated rotating shaft and the fourth connecting plate are integrally formed.
[0016] Optionally, there are multiple quick-release hinges, which are spaced apart on the edge.
[0017] Alternatively, the solar panel unit may be made of lightweight materials.
[0018] The advantages of the portable foldable solar panel based on quick-release hinges provided in this application are as follows: This portable foldable solar panel, through its unique quick-release hinge and integrated structural design, achieves a "one-insert-lock, one-press-open" operation, enabling quick assembly and disassembly without any tools. This allows for rapid unfolding, folding, or disassembly of the entire solar panel into smaller units for storage, resulting in a smaller storage volume and significantly improving the user experience. It is particularly suitable for outdoor scenarios such as backpacking and road trips. Furthermore, the mechanical locking design of the quick-release hinge ensures the robustness of the connection between each solar panel unit, resisting a certain degree of wind swaying. Compared to flexible folding panels and rigid panels with simple hinge connections, it offers greater stability and durability, thus guaranteeing the power generation efficiency and lifespan of the solar panel. Moreover, this quick-release hinge design highly integrates multiple functions such as rotation, locking, and quick separation into a compact hinge component, offering advantages such as high functional integration, ingenious structure, and aesthetic appeal. Furthermore, if a solar panel unit or quick-release hinge is damaged, the faulty unit can be quickly replaced without scrapping the entire solar panel, reducing subsequent maintenance costs. In summary, this portable foldable solar panel based on quick-release hinges offers numerous advantages, including portability, quick assembly and disassembly, reliable connection, robust structure, high functional integration, and easy maintenance.

[0035] This application provides a portable foldable solar panel based on a quick-release hinge.
[0036] Please see Figures 1 to 6In one embodiment, the portable foldable solar panel based on a quick-release hinge includes a solar panel unit 100 and a quick-release hinge 200. Specifically, the solar panel unit 100 is flat and includes a frame 110 and a solar panel 120, which is mounted within a frame formed by connecting multiple frames 110 end to end. Two adjacent solar panel units 100 are connected by a quick-release hinge 200; the quick-release hinge 200 includes a male connector assembly and a female connector assembly; the male connector assembly includes a male connector 211, a locking pin 212, an integrated pivot 213, an elastic locking member 214, and a lever 215; the female connector assembly includes a female connector 221 and a locking engagement part 222; the female connector 221 is connected to a frame 110 of one solar panel unit 100, and the female connector 221 is shaped towards the outer edge of another solar panel unit 100. It has a locking groove 223 and a locking mating part 222, and a pin hole 224 is formed on the locking mating part 222; the male connector 211 is connected to a side frame 110 of the corresponding side of the adjacent solar panel unit 100, and an integrated rotating shaft 213 is provided at the outer edge of the male connector 211 facing the female assembly. The locking pin 212 and the elastic locking member 214 are built into the axially hollow integrated rotating shaft 213, and the elastic locking member 214 is sleeved on the inner end of the locking pin 212; the lever 215 is connected to the locking pin 212. The quick-release hinge 200 has a locked state and an open state. In the locked state, the integrated pivot 213 is housed in the locking groove 223, and the elastic locking member 214 elastically abuts against the locking pin 212, so that the outer end of the locking pin 212 extends out of the integrated pivot 213 and is inserted into the pin hole 224, thus locking the male and female components together. In the open state, the lever 215 moves the locking pin 212, the elastic locking member 214 is compressed, the locking pin 212 retracts to disengage from the pin hole 224, and the male and female components separate.
[0037] In actual use, when the solar panel unit 100 needs to be installed, the male connector component should first be brought close to the female connector component. The integrated shaft 213 is inserted into the locking groove 223. At this time, pressure is applied during the insertion of the male connector component into the female connector component. The locking pin 212 will slide inward along the inner wall of the integrated shaft 213, compressing the elastic locking member 214 until the locking pin 212 slides into the pin hole 224 on the aligned locking mating part 222. The elastic locking member 214 rebounds and makes a "click" sound, thus completing the quick connection and locking of the male connector component and the female connector component. The two solar panel units 100 are connected. The entire installation process does not require any tools and is very quick and convenient. When the solar panel unit 100 needs to be disassembled, simply press the lever 215 to retract the elastic locking member 214, thereby causing the locking pin 212 to disengage from the pin hole 224, releasing the restriction on the locking pin 212, and then the male component can be easily pulled out from the female component, thus achieving rapid separation of the two adjacent solar panel units 100.
[0038] Based on this structural design, in this embodiment, the portable foldable solar panel based on the quick-release hinge achieves "one-plug lock, one-press open" operation through the unique quick-release hinge 200 and integrated structural design. It allows for quick assembly and disassembly without any tools, enabling the entire solar panel to be unfolded, folded, or disassembled into smaller units for storage in a short time. This results in a smaller storage volume, greatly improving the user experience and making it particularly suitable for outdoor scenarios such as backpacking and road trips. Of course, the mechanical locking design of the quick-release hinge 200 also ensures the robustness of the connection between the solar panel units 100, resisting a certain degree of wind swaying. Compared to flexible folding panels and rigid panels with simple hinge connections, it has the advantages of being more stable and durable, thus ensuring the power generation efficiency and lifespan of the solar panel 120. Moreover, this quick-release hinge 200 design highly integrates multiple functions such as rotation, locking, and quick separation into a compact hinge component, offering advantages such as high functional integration, ingenious structure, and aesthetic appeal. Furthermore, if a solar panel unit 100 or quick-release hinge 200 is damaged, the faulty unit can be quickly replaced individually without scrapping the entire solar panel, reducing subsequent maintenance costs. In summary, this portable foldable solar panel based on quick-release hinges has many advantages, including easy portability, quick assembly and disassembly, reliable connection, robust structure, high functional integration, and convenient maintenance.
[0039] It should be noted that the solar panel unit 100 of this portable foldable solar panel based on quick-release hinge is made of lightweight materials and is a lightweight rigid solar panel 120. Its overall weight is much lighter than that of traditional metal frame solar panels, making it more convenient to carry. It effectively solves the problem of traditional foldable solar panels being difficult to balance portability and structural rigidity, and is more suitable for outdoor scenarios.
[0040] Furthermore, to ensure a more secure connection between two adjacent solar panel units 100, multiple quick-release hinges 200 are used, and these hinges 200 are spaced apart on the frame 110. Specifically, in this embodiment, as... Figure 1 and Figure 3 As shown, two quick-release hinges 200 are provided at intervals on the corresponding two side frames 110 of the two solar panel units 100, respectively located at approximately one-quarter and three-quarters of the position of the side frame 110. However, this design is not limited to this. In other embodiments, the number of quick-release hinges 200 provided on a corresponding set of side frames 110 can be three or more. It is not limited to the connection of two solar panel units 100, but can also be the connection of multiple solar panels 120. It is not limited to the connection of one side of the side frame 110, but can also be the connection of multiple side frames 110 via quick-release hinges 200.
[0041] Please see Figures 1 to 6 In this embodiment, the first frame 111 is connected to the female connector assembly, and the second frame 112 is connected to the male connector assembly. Both the first frame 111 and the second frame 112 include adjacent outer and inner surfaces. The female connector connector 221 includes an integrally connected first connecting plate 225 and a second connecting plate 226. The first connecting plate 225 is fitted and fixedly connected to the outer surface of the first frame 111, and the second connecting plate 226 is fitted to the inner surface of the first frame 111. A locking groove 223 and a locking engagement portion 222 are formed on the outer edge of the second connecting plate 226 away from the first connecting plate 225. The male connector connector 211 includes an integrally connected third connecting plate 216 and a fourth connecting plate 217. The third connecting plate 216 is fitted and fixedly connected to the outer surface of the second frame 112, and the fourth connecting plate 217 is fitted to the inner surface of the second frame 112. An integrated pivot 213 is formed on the outer edge of the fourth connecting plate 217 away from the third connecting plate 216. Specifically, the vertical cross-sections of the first frame 111 and the second frame 112 are both rectangular or square, so the vertical cross-sections of the female connector 221 and the male connector 211 are both L-shaped. Multiple screw holes are provided on the first connecting plate 225 and the third connecting plate 216 to facilitate screwing and fixing to the outer surface of the frame 110. This shape design, combined with the one-piece integrated hinge 213, not only makes the connection between the male connector 211 and the female connector 221 and the corresponding frame 110 more stable, but also allows for 180-degree rotation, enabling the two solar panel units to fully unfold into a flat shape and fold completely over each other.
[0042] Furthermore, such as Figure 2 , Figures 4 to 6As shown, the locking engagement part 222 and the second connecting plate 226 are integrally formed, as are the integrated rotating shaft 213 and the fourth connecting plate 217. Specifically, the locking engagement part 222 is formed by two legs extending outward from the outer edge of the second connecting plate 226 and curling upward; the integrated rotating shaft 213 is also formed by a protruding portion at the outer edge of the fourth connecting plate 217 curling upward. Here, since the integrated rotating shaft 213 is integrally formed, when the quick-release hinge 200 is in the locked state, i.e., when two adjacent solar panel units 100 are connected, the two adjacent solar panel units 100 can rotate around the integrated rotating shaft 213 from 0 to 180 degrees, or even 360 degrees, thereby achieving better folding and unfolding of the solar panel units 100.
[0043] Please see Figure 5 and Figure 6 In this embodiment, two locking engagement parts 222 are provided, respectively located on both sides of the outer edge of the fourth connecting plate 217. The two spaced-apart locking engagement parts 222 form an externally open locking groove 223 between the two spacesd locking engagement parts 222 and the outer edge of the fourth connecting plate 217. Correspondingly, in this embodiment, there are two locking pins 212 and two levers 215. Each locking pin 212 is fixedly connected to one lever 215, and both ends of the elastic locking member 214 are respectively sleeved on the inner ends of the two locking pins 212. Here, the elastic locking member 214 is preferably a spring, but it can also be other elastic structures. The provision of two locking engagement parts 222 allows the quick-release hinge 200 to achieve the locking function of the locking pins 212 on both sides, which is beneficial to further improve the stability and reliability of the locking mechanism and prevent the solar panel units 100 from accidentally bending or loosening during use. The design of two locking pins 212 sharing one elastic locking member 214 ensures the locking function and makes the structural design more integrated and compact.
[0044] Please see Figure 5 and Figure 6 In this embodiment, both the locking pin 212 and the lever 215 are cylindrical, and their axes are perpendicular to each other. Specifically, a screw hole is provided on the outer side of the locking pin 212 near the elastic locking member 214, and an external thread is provided on the end of the lever 215 facing the locking pin 212. The lever 215 is detachably screwed into the screw hole by rotating through the external thread to achieve a detachable connection with the locking pin 212. The perpendicular arrangement of the locking pin 212 and the lever 215 after connection facilitates the movement of the lever 215 during disassembly and assembly. Moreover, in the locked state, the lever 215 can also be placed on the fourth connecting plate 217 and fit against the fourth connecting plate 217, thereby avoiding obstruction when the solar panel 120 is unfolded.
[0045] Furthermore, in this embodiment, as Figure 5 and Figure 6As shown, the integrated pivot 213 has an elongated hole 218 extending axially. The end of the lever 215 connected to the locking pin 212 can be moved back and forth within the elongated hole 218. It can be understood that the elongated hole 218 mainly serves to limit the movement of the lever 215, so that the extension and retraction of the locking pin 212 are within a predetermined range, thereby improving the stability of the locking mechanism of the quick-release hinge 200.
[0046] In addition, such as Figure 2 as well as Figures 4 to 6 As shown, in this embodiment, a limiting portion 219 is also formed at the outer edge of the fourth connecting plate 217. The limiting portion 219 is located beside the integrated rotating shaft 213. In the locked state, the limiting portion 219 is limited and abuts against the locking mating portion 222. Specifically, the limiting portion 219 is formed by bending upwards from the two protruding support legs on both sides of the fourth connecting plate 217. The setting of this limiting portion 219 allows the integrated rotating shaft 213 to be adapted to be inserted into the locking groove 223, thereby ensuring that the locking pin 212 and the pin hole 224 are accurately aligned, and the locking pin 212 can smoothly enter and exit the pin hole 224.
[0047] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
