[0033] This utility model proposes a solar charger.

[0034] In the embodiments of this utility model, such as Figures 1 to 4 As shown, the solar charger includes a mounting base 10, multiple solar panels 20, circuitry, and a transparent protective layer 30.

[0035] Specifically, the mounting base 10 includes multiple mounting portions 11 and multiple flexible portions 12. The multiple mounting portions 11 are spaced apart along a first direction, and adjacent two mounting portions 11 are connected by a flexible portion 12. The mounting base 10 has a folded state in which the multiple mounting portions 11 are stacked and an unfolded state in which they are unfolded relative to the folded state. This allows the user to unfold the mounting base 10 to the unfolded state when they need to charge the electronic device with a solar charger, and to fold the mounting base 10 to the folded state for storage after the user has finished charging, thereby reducing the space occupied.

[0036] Multiple solar panels 20 are connected in series, and each solar panel 20 is installed in a corresponding mounting part 11; the circuit device includes a circuit board and a connection interface 60. The circuit board is provided with a charging circuit, which is electrically connected to the solar panel 20. The connection interface 60 is electrically connected to the charging circuit and is exposed on the surface of the mounting base 10; a transparent protective layer 30 covers the surface of the multiple solar panels 20.

[0037] Each solar panel 20 is installed in a corresponding mounting part 11. In the folded state, multiple solar panels 20 are stacked. In the unfolded state, each solar panel 20 faces the sunlight to maximize the solar energy receiving area and improve charging power. Since solar energy is a very mature technology and has been widely used in the market, this application will not elaborate on the technical principles and detailed structures of solar energy.

[0038] A transparent protective layer 30 covers the surface of the solar panel 20 to protect it. This prevents damage to the solar panel 20 even if other objects scrape against it, thus extending its lifespan. Furthermore, the transparent protective layer 30 is transparent, allowing sunlight to pass through and illuminate the solar panel 20.

[0039] The type of the connection interface 60 can be, but is not limited to, Type-C, Type-B, Lightning, etc., and can be set according to the actual situation. In addition, in other embodiments, the circuit device includes multiple connection interfaces 60, each of which is electrically connected to the charging circuit and is exposed on the surface of the mounting base 10. The type of each connection interface 60 is different to suit different types of electronic devices.

[0040] This utility model's technical solution involves distributing multiple mounting portions 11 of a mounting base 10 at intervals along a first direction, with adjacent mounting portions 11 connected by a flexible portion 12. The mounting base 10 has a folded state with multiple mounting portions 11 stacked together and an unfolded state relative to the folded state. This allows the user to unfold the mounting base 10 when charging electronic devices via a solar charger, and fold it back into its folded state for storage after charging, reducing space occupation. Multiple solar panels 20 are connected in series, with each solar panel 20 correspondingly mounted on a mounting portion 11. A charging circuit is provided through a circuit section, electrically connecting the charging circuit to the solar panel 20. The connection interface 60 of the circuit device is exposed on the surface of the mounting base 10. A transparent protective layer 30 covers the surfaces of the multiple solar panels 20, providing protection against scratches from other objects rubbing against the solar charger, thus extending the lifespan of the solar panels 20.

[0041] In some embodiments, the transparent protective layer 30 includes a first composite film 31 and a first adhesive layer 32, with the first composite film 31 disposed between the solar panel 20 and the first adhesive layer 32. Specifically, the first composite film 31 has a stress-relieving function, preventing damage to the solar panel 20 under external force, thus improving the service life of the solar panel 20. The first adhesive layer 32 serves as an adhesive material, used to bond the solar panel and the first composite film 31 to the mounting portion 11, while also preventing moisture from penetrating onto the solar panel 20. Optionally, the first adhesive layer 32 is made of EVA adhesive.

[0042] Furthermore, the first composite film 31 is made of a mixture of glass fiber and resin. Specifically, glass fiber has high strength and elasticity, as well as high light transmittance, while resin has good adhesion. The first composite film 31 made of glass fiber and resin has high strength, high elasticity, high light transmittance, and high adhesion, which makes the first composite film 31 structurally strong and able to be stably bonded to the surface of the solar panel 20.

[0043] In some embodiments, the transparent protective layer 30 further includes a thin film layer 33, which covers the surface of the first adhesive layer 32. Specifically, the thin film layer 33 is made of ETFE film, which has excellent light transmittance, can reduce the impact on the solar panel 20's reception of sunlight, and can also prevent moisture from passing through, thus helping to improve the lifespan of the solar panel.

[0044] In some embodiments, the solar charger further includes a protective layer 40 disposed between the solar panel 20 and the mounting portion 11. Specifically, the solar panel 20 is located between the protective layer 40 and the transparent protective layer 30, which provides protection for both the upper and lower sides of the solar panel 20, thereby further extending the lifespan of the solar panel 20. Furthermore, in other embodiments, the solar charger does not include a protective layer 40.

[0045] In some embodiments, the protective layer 40 includes a second composite film 41 and a second adhesive layer 42, wherein the second composite film 41 is disposed between the second adhesive layer 42 and the solar panel 20. Specifically, the second composite film 41 has a stress-relieving function, which can prevent the solar panel 20 from being damaged under external force, thus helping to extend the service life of the solar panel 20. The second adhesive layer 42 serves as an adhesive material for bonding the solar panel and the second composite film 41 to the mounting portion 11. Optionally, the second adhesive layer 42 is made of EVA adhesive.

[0046] In some embodiments, the protective layer 40 further includes an epoxy board 43 and a third adhesive layer 44. The epoxy board 43 is located between the third adhesive layer 44 and the second composite film 41, and the third adhesive layer 44 is located between the epoxy board 43 and the mounting portion 11. Specifically, the epoxy board 43 has high hardness and rigidity, which, when applied to this solution, can improve the structural strength of the solar panel 20. The second adhesive layer 42 serves as an adhesive material for bonding the epoxy board 43 and the second composite film 41 to the mounting portion 11. Optionally, the third adhesive layer 44 is made of EVA adhesive.

[0047] In some embodiments, the solar charger further includes a connecting strap 50, which is connected to the mounting portion 11. The connecting strap 50 is provided with a first fixing member, and the mounting base 10 is provided with a second fixing member. The first fixing member and the second fixing member are connected to fix the mounting base 10 in a folded state. Specifically, when the user folds the mounting base 10 to a folded state for storage, the first fixing member and the second fixing member are connected to fix the mounting base 10 in the folded state, thus preventing the mounting base 10 from unfolding naturally. When the user needs to use the solar charger, they only need to separate the first fixing member and the second fixing member to unfold the mounting base 10 to the unfolded state, which is convenient and quick, and improves the user experience.

[0048] Furthermore, the first fixing member includes a first magnetic suction member 51, and the second fixing member includes a second magnetic suction member (not shown). The first magnetic suction member 51 and the second magnetic suction member magnetically engage to fix the mounting base 10 in a folded state. When the user folds the mounting base 10 to the folded state for storage, the first magnetic suction member 51 and the second magnetic suction member magnetically engage to fix the mounting base 10 in the folded state. The first magnetic suction member 51 and the second magnetic suction member can be magnets or ferromagnetic metals (such as iron, cobalt, and nickel).

[0049] In some embodiments, the mounting base 10 is further provided with a suspension part, through which the solar charger is hung. Specifically, when a user needs to charge an electronic device using the solar charger while walking, the solar charger can be hung on a backpack using the suspension part, eliminating the need for the user to hold it by hand, thus improving the user experience of the solar charger. Furthermore, in other embodiments, the mounting base 10 does not have a suspension part.

[0050] Furthermore, the suspension unit includes two through holes 13, which are located on the same side of the mounting base 10 and spaced apart from each other. Specifically, users can hang the solar charger through the two through holes 13. This design simplifies the structure and reduces manufacturing complexity.

[0051] In some embodiments, two adjacent solar panels 20 are connected by copper foil, and the solar panel also includes two protective sheets, which are disposed on the upper and lower sides of the copper foil respectively.

[0052] Specifically, protective sheets are provided on both the top and bottom sides of the copper foil to protect it from breakage. This improves the connection stability between adjacent solar panels, thus extending the lifespan of the solar charger. Alternatively, in other embodiments, the solar panels do not have protective sheets. Optionally, the protective sheets are made of polyester Oxford cloth.

[0053] In some embodiments, the solar charger further includes an indicator light 70, which is electrically connected to the circuit board and exposed on the surface of the mounting base 10. Specifically, in the unfolded state, when the solar panel 20 receives sunlight, the indicator light 70 is illuminated; when the solar panel does not receive sunlight, the indicator light 70 is off. This allows the user to determine whether the electronic device can be charged by checking the status of the indicator light 70, thus improving the user experience. Furthermore, in other embodiments, the solar charger does not include an indicator light 70.

[0054] In some embodiments, the solar charger further includes a rubber plug disposed at the connection interface 60 for opening and sealing the connection interface 60. Specifically, the rubber plug is used to prevent dust and water from flowing into the connection interface 60, thereby improving the dustproof and waterproof performance of the solar charger. In other embodiments, the solar charger does not include a rubber plug.

[0055] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using 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.
