[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Refer to Figure 1 、 Figure 3 And Figure 7, An embodiment provided by the utility model: a foldable and portable photovoltaic charging device, including multiple carrier plates 1, which play a key supporting role in the device. Two elastic fabrics 2 are connected at the intervals of the multiple carrier plates 1. The material of the elastic fabric 2 is spandex. This spandex material elastic fabric 2 has excellent elastic stretching performance. When the device is folded, the elastic fabric 2 can naturally stretch and contract along with the movement of the carrier plates 1, making the folding process smoother. At the same time, the spandex material also has certain wear resistance and anti-aging properties, and can maintain good performance during long-term use. The top ends of the two left carrier plates 1 are fixedly connected with a photovoltaic panel 3. As the core component of the device, the photovoltaic panel 3 can convert solar energy into electrical energy to provide a charging power source for electronic devices. A gasket 4 is sleeved outside the photovoltaic panel 3, which can play a role in protecting the photovoltaic panel 3. The gasket 4 can buffer the external impact force and prevent the photovoltaic panel 3 from being damaged by collision and scratching during carrying and use;

[0027] One side of the left gasket 4 is in contact with the bottom end of the right carrier plate 1. This design enables the components of the device to fit closely together in the folded state, reducing the occupied space and facilitating carrying. At the same time, this contact can also increase the stability of the device and prevent loosening and shaking during carrying. Two receiving blocks 5 are fixedly connected to the bottom ends of the two left carrier plates 1. A rotating block 6 is movably connected to one side inside the receiving block 5. This movable connection allows the rotating block 6 to rotate and slide simultaneously;

[0028] Limiting holes 7 are opened on both the front and rear sides of the rotating block 6. A limiting block 8 is slidably connected inside the limiting hole 7. When the rotating block 6 rotates and slides, the limiting block 8 can move inside the limiting hole 7 to limit the movement range of the rotating block 6 and prevent the device from being damaged due to excessive movement of the rotating block 6. At the same time, the cooperation between the limiting block 8 and the limiting hole 7 can also increase the stability of the device and ensure that the device will not have accidental loosening and deformation during use. A sliding block 9 is fixedly connected to the adjacent sides of every two limiting blocks 8. The outside of the sliding block 9 is slidably connected inside the rotating block 6. This connection enables the sliding block 9 to slide smoothly inside the rotating block 6. A rotating rod 10 is rotatably connected to the other side inside the receiving block 5. The outside of the rotating rod 10 is in contact with the rotating block 6.

[0029] Refer to Figure 2 and Figure 5, a spring 11 is provided inside the rotating rod 10 to provide spring force and supporting force. A sliding rod 12 is slidably connected to the inner wall of the bottom end of the rotating rod 10. The bottom end of the sliding rod 12 is rotatably connected to the inside of one side of the sliding block 9, thereby further increasing the flexibility and adjustability of the device, facilitating subsequent folding. The top end of the sliding rod 12 is fixedly connected with a limiting disc 13. This limiting disc 13 is used to limit the position of the sliding rod 12. One end of the spring 11 is fixedly connected to one side inside the rotating rod 10, and the other end of the spring 11 is fixedly connected to one side of the limiting disc 13. The outside of the limiting disc 13 is slidably connected to the inside of the rotating rod 10.

[0030] Refer to Figure 4 and Figure 6 , locking components are fixedly connected to the left ends of the two accommodating blocks 5 on the left side. This locking component plays an important fixing role in the device, ensuring that the device remains stable in the folded state and preventing the various components from accidentally spreading apart. The locking component includes male fasteners 14. The right ends of the two male fasteners 14 are respectively fixedly connected to the left ends of the two accommodating blocks 5 on the left side. Female fasteners 15 are fixedly connected to the right ends of the two accommodating blocks 5 on the right side. The male fasteners 14 and the female fasteners 15 are detachably connected. This design enables the device to be quickly opened and closed during use, facilitating user operation. When the device needs to be used, simply press the male fastener 14 gently to separate it from the female fastener 15 and unfold the device for operations such as charging. When carrying or storing the device, the device can be locked by inserting the male fastener 14 into the female fastener 15 to ensure the safety of the device. Carrying handles 16 are fixedly connected to the far sides of the bottom ends of the two loading plates 1 on the left side. The design of the carrying handles 16 provides great convenience for users, making the device more easily carried.

[0031] Refer to Figure 1 , a receiving plate 17 is fixedly connected to the top end of the right loading plate 1. This receiving plate 17 provides an additional functional area for the device. One side of the middle-end gasket 4 is in contact with one side of the receiving plate 17. This contact can play a certain buffering role during the folding or unfolding process of the device. A plurality of charging holes 18 are respectively opened in the front and rear sides inside the top end of the receiving plate 17. These charging holes 18 can provide charging interfaces for various electronic devices, facilitating users to charge devices such as mobile phones, tablet computers, cameras, etc. outdoors or other occasions. A storage groove 19 is opened in the middle of the top of the loading plate 1. This storage groove 19 can be used to store some small charging accessories, data cables or cleaning items, making the device more tidy and orderly during use, and also facilitating users to access these items at any time. Two protective plates 20 are slidably connected to the inside of the top end of the receiving plate 17. These two protective plates 20 can play a protective role when the charging holes 18 are not in use, preventing dust, debris or moisture from entering the charging holes 18, thereby extending the service life of the device. A pull rod 21 is fixedly connected to the top end of the protective plate 20.

[0032] Working Principle: This foldable portable photovoltaic charging device primarily consists of multiple loading plates 1, which serve as a key support mechanism. Spatula-like elastic fabric 2 is inserted between the loading plates 1. When the device folds, the movement of the loading plates 1 causes the elastic fabric 2 to naturally stretch and contract, making the folding process smoother. Furthermore, the spandex elastic fabric 2 exhibits a certain degree of wear resistance and aging resistance, ensuring it maintains good performance over long-term use.

[0033] Photovoltaic panels 3 are fixedly attached to the tops of the two left-side carriers 1. These panels, as core components, convert solar energy into electricity, providing charging power for electronic devices. Gaskets 4, mounted on the outside of the panels, cushion the impact of external forces on the device, protecting the panels 3 from damage caused by collisions and scratches. One side of the left gasket 4 contacts the bottom of the right-side carrier 1, ensuring a tight fit when the device is folded. This reduces space consumption and facilitates portability, while also increasing stability and preventing loosening and shaking during transport.

[0034] To fold the device, first move the sliding rod 12. This movement of the sliding rod 12 causes the limiting plate 13 to slide inside the rotating rod 10 due to the restraint of the rotating block 6. The sliding of the limiting plate 13 causes the spring 11 to contract, and the sliding block 9 causes the limiting block 8 to slide inside the limiting hole 7, which in turn causes the rotating block 6 to rotate, completing the contraction of the rotating block 6. The spring 11 acts to ensure the stability of the rotating block 6 and provide support. The left ends of the two left accommodating blocks 5 are fixedly connected to the locking assembly, which includes a male buckle 14. The right ends of the male buckle 14 are respectively fixed to the left ends of the two left accommodating blocks 5. The right ends of the two right accommodating blocks 5 are fixedly connected to the female buckle 15, which is detachably connected to the male buckle 14. When carrying or storing the device, the male buckle 14 is inserted into the female buckle 15 to lock the device and ensure its safety. When the device is needed, the male buckle 14 is gently pressed to separate it from the female buckle 15, allowing the device to be unfolded for charging and other operations. The carrying handles 16 fixedly connected to the far side of the bottom ends of the two left loading boards 1 provide great convenience for the user, making the device easier and more convenient to carry.

[0035] The receiving plate 17 fixedly connected to the top end of the right load-carrying plate 1 provides an additional functional area for the device. One side of the middle-end gasket 4 is in contact with one side of the receiving plate 17, playing a certain buffering role during the folding or unfolding process of the device. A plurality of charging holes 18 opened inside the front and rear sides at the top end of the receiving plate 17 can provide charging interfaces for various electronic devices, facilitating users to charge devices such as mobile phones, tablet computers, cameras, etc. outdoors or in other scenarios. The storage groove 19 opened in the middle end at the top of the load-carrying plate 1 can be used to store small charging accessories, data cables or cleaning items, making the device more tidy and orderly during use and facilitating users to access these items at any time. Two protective plates 20 slidably connected to the inside of the top end of the receiving plate 17 play a protective role when the charging holes 18 are not in use, preventing dust, debris or moisture from entering the charging holes 18, thereby extending the service life of the device. The pull rod 21 fixedly connected to the top end of the protective plate 20 facilitates users to pull the protective plate 20 for opening and closing operations.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements of some technical features.
