Description

Technical Field

[0001] This utility model relates to a solar-powered power bank, belonging to the field of photoelectric conversion technology. Background Technology

[0002] Power banks, also known as "portable power banks," "external batteries," "backup batteries," "digital charging companions," "external batteries," or simply "portable power supplies," are a concept that has developed alongside the widespread adoption and rapid growth of digital products. They are defined as convenient and portable power sources. With the increasing diversification of digital product functions, more frequent use, and closer integration into our daily lives, the importance of extending the lifespan of digital products, facilitating people's lives, providing timely power replenishment, and maximizing their functionality has become increasingly urgent. Portable power banks are the best solution to this problem. Carrying a portable power bank allows you to charge various digital products anytime, anywhere. With the development of solar energy technology, many power bank products have expanded their solar energy functionality.

[0003] Conventional solar power banks use foldable photovoltaic panels to increase the area of ​​the photovoltaic panels and achieve the effect of absorbing more light energy. However, folding the photovoltaic panels increases the thickness of the power bank, and the expanded photovoltaic panels protrude from the power bank's outer casing, posing a risk of damage.

[0025] Please refer to Figures 1 to 3 An embodiment of this application shows a solar power bank, which includes a main body unit 10 and a concentrating unit 20.

[0026] The main unit 10 includes a panel box 11, a solar panel 13 disposed on the top of the panel box 11, and a charging component disposed on the side of the panel box 11. The solar panel 13 is electrically connected to the charging component. The solar panel 13 is used to absorb light energy and convert it into electrical energy, and the charging component is used to connect to and charge peripheral devices. Both of these are existing technologies and will not be described in detail here.

[0027] The concentrating unit 20 is detachably connected to the panel box 11 and located above the solar panel 13. The concentrating unit 20 includes a concentrating component and a pair of cover plates 24 rotatably connected to both sides of the concentrating component. The panel box 11 has insertion slots 16 for inserting the cover plates 24, and the pair of insertion slots 16 are located on both sides of the solar panel 13. The cover plates 24 are rotatably connected to the concentrating component. Under normal conditions, the cover plates 24 cover the upper surface of the concentrating component, which can effectively protect the concentrating component and prevent it from being scratched, thus affecting the concentrating effect.

[0028] The concentrating unit 20 has two concentrating modes. Concentrating mode one: The concentrating unit 20 is removed from the main unit 10, and the two cover plates 24 are rotated 90° each so that they are perpendicular to the concentrating component. Then, they are flipped 180° to insert the two cover plates 24 into the insertion slots 16. In this mode, the distance between the concentrating component and the solar panel 13 is at its maximum. Concentrating mode two: The cover plates 24 are rotated more than 90° to open them, preventing them from obstructing the concentrating component. Sunlight shines through the concentrating component onto the solar panel 13. In this mode, the distance between the concentrating component and the solar panel 13 is at its minimum. By placing the concentrating component above the solar panel, the light shining on the concentrating component can be focused onto the solar panel 13. The resulting light spot area has a higher energy concentration effect, and areas on the solar panel where no light spot is formed will also absorb light, thus improving the photoelectric conversion efficiency.

[0029] In one embodiment, a storage cavity 12 is formed on the top of the panel box 11, and the solar panel 13 is disposed at the bottom of the storage cavity 12. The outer surface of the light-concentrating unit 20 is flush with the top surface of the panel box 11. This arrangement ensures that the cover plate 24 is stored in the storage cavity 12, preventing the light-concentrating unit 20 from falling off the main unit 10.

[0030] In one embodiment, the focusing assembly includes a fixing frame 21 and a focusing lens 22 disposed within the fixing frame 21. A holding member 23 is arranged on the inner wall of the receiving cavity 12 at a position corresponding to the side of the fixing frame 21. The holding member 23 is a magnetic strip; a magnetic strip a231 is disposed within the receiving cavity 12, and a magnetic strip b232 is disposed on the side of the fixing frame 21. The magnetic strips a231 and b232 attract each other, enabling quick assembly and disassembly of the focusing unit 20 from the main unit 10.

[0031] In one embodiment, a staircase is arranged around the storage cavity 12, and a step 211 adapted to the staircase is formed on the fixing frame 21. This arrangement facilitates the interlocking of the fixing frame 21 and the panel box 11, preventing their displacement, and facilitates the fixing of the condenser lens 22 with the help of the magnetic strip.

[0032] In one embodiment, a rotating column is formed on the cover plate 24, and a connecting sleeve is formed on the fixed frame 21, with the connecting sleeve fitted onto the rotating column. This arrangement facilitates the mutual rotation between the cover plate 24 and the fixed frame 21 to switch the focusing mode.

[0033] In one embodiment, the length of the pair of cover plates 24 is equal to the length of the fixing frame 21. This arrangement facilitates the cover plates 24 to cover the condenser lens 22 to provide protection, while the condenser lens 22 remains parallel to the solar panel 13 when the cover plates 24 are inserted upside down into the insertion slot 16.

[0034] In one embodiment, grooves 241 are formed on both sides of the cover plate 24 to facilitate rotation. The grooves 241 on both sides of the cover plate 24 facilitate opening the cover plate 24.

[0035] In one embodiment, the charging assembly includes a plurality of charging ports 14 disposed on the panel box 11 and a dust cover covering the outside of the charging ports 14. By providing multiple charging ports 14, it is convenient to charge different external devices. At the same time, when not charging, the charging ports 14 can be protected by the dust cover 15.

[0036] This application achieves improved photoelectric conversion efficiency of solar panels without increasing their area by arranging a concentrating unit 20 above the solar panel. Alternatively, the concentrating unit can be opened to focus sunlight onto the solar panel, or it can be removed from the top of the solar panel, and the cover and concentrating unit can be rotated 90° and inserted upside down into the insertion slot on the panel box to focus sunlight onto the solar panel.

[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
