[0026] By installing a telescopic rod 15 and rollers 16 on the support frame 1, the user can move the charger by pulling the telescopic rod 15, improving the convenience of movement. The mutual attraction between the magnet 36 and the extension strip 14 facilitates the disassembly of the foldable solar panel 3; the foldable solar panel 3 surrounds the outside of the battery 2, providing protection. When the battery 2 is charging, the foldable solar panel 3 can be removed to enhance heat dissipation. The second solar panel 32 is connected to the first solar panel 31 and the third solar panel 33 via the first flexible strip 34 and the second flexible strip 35 respectively, forming a foldable structure. When folded, the volume is reduced, making it easy to carry and store, suitable for outdoor use. Furthermore, the integrated hot-pressing process enhances the durability of the first solar panel 31, the second solar panel 32, and the third solar panel 33; the fiberglass coating prevents microcracks; and the FR4 cell base plate provides mechanical support and electrical isolation. This solves the problems of current solar chargers being insufficiently portable and lacking flexibility in use.

[0027] In some embodiments, the side plate 13 is provided with ball-head nails 17, and nail holes 37 are provided on the other side of the first solar panel 31 and the other side of the third solar panel 33, with the ball-head nails 17 and nail holes 37 corresponding one-to-one.

[0028] Reference Figure 2 The ball-head nail 17 is used to lock the nail hole 37, which increases the stability of the connection between the support frame 1 and the foldable solar panel 3. In addition, the one-to-one correspondence between the ball-head nail 17 and the nail hole 37 allows users to easily and quickly perform installation and disassembly operations.

[0029] Preferably, both the first solar panel 31 and the third solar panel 33 are provided with handles 38, which are located on the side near the ball head nail 17.

[0030] Reference Figure 2 The handle 38 is designed to make it easy for users to grip the foldable solar panel 3, thereby facilitating the disassembly, installation, and angle adjustment of the foldable solar panel 3.

[0031] In some embodiments, the first solar panel 31, the second solar panel 32 and the third solar panel 33 are all provided with grooves 39, and the two sides of the first flexible strip 34 and the two sides of the second flexible strip 35 are provided with protrusions 310, which are engaged in the grooves 39.

[0033] In some embodiments, a support assembly 311 is provided on the back of the foldable solar panel 3. The support assembly 311 includes a support plate 3111, an elastic rope 3112, a first limiting rope 3113, and a second limiting rope 3114. The top end of the support plate 3111 is connected to the back of the foldable solar panel 3. One end of the elastic rope 3112, one end of the first limiting rope 3113, and one end of the second limiting rope 3114 are connected to each other. The other end of the elastic rope 3112 is connected to the top of the support plate 3111. The other end of the first limiting rope 3113 is connected to the foldable solar panel 3. The other end of the second limiting rope 3114 is connected to the bottom of the support plate 3111. The first limiting rope 3113 and the second limiting rope 3114 form an angle greater than 0° and less than 180°.

[0034] Reference Figure 5 , Figure 5 The angle α is the included angle between the first limiting rope 3113 and the second limiting rope 3114. The support assembly 311 is small in size and easy to store. The support plate 3111 and the foldable solar panel 3 are firmly connected by the elastic rope 3112, the first limiting rope 3113, and the second limiting rope 3114, preventing the foldable solar panel 3 from swaying or tipping over due to wind when unfolded. The included angle formed by the first limiting rope 3113 and the second limiting rope 3114 allows users to flexibly adjust the angle of the foldable solar panel 3 according to the position of the sun to maximize the light energy absorption efficiency. The elasticity of the elastic rope 3112 can automatically adjust the angle of the support plate 3111 to a certain extent, ensuring that the foldable solar panel 3 always maintains a relatively stable state and can quickly restore balance even under slight wind or external impact.

[0035] Preferably, the back of the foldable solar panel 3 is provided with hook-and-loop fasteners 312, and the bottom of the support plate 3111 is provided with hook-and-loop fasteners on the side near the foldable solar panel 3, with the hook-and-loop fasteners 312 and the hook-and-loop fasteners corresponding one to one.

[0036] Reference Figures 5-6 By attaching the hook and loop fasteners 312 and the rough hook and loop fasteners, the support plate 3111 can be connected to the foldable solar panel 3 for easy storage.

[0037] Preferably, there are three support components 311, which are respectively disposed on the back of the first solar panel 31, the second solar panel 32 and the third solar panel 33.

[0038] Reference Figures 5-6 By setting up three independently operating support components 311, the weight and stress borne by the foldable solar panel 3 are distributed more evenly, avoiding structural deformation or damage caused by excessive force on a single point; on the other hand, multi-point support is provided to prevent the foldable solar panel 3 from swaying or tipping over.

[0039] In some embodiments, the foldable solar panel 3 is also provided with a storage bag 313, which contains a junction box and an MC4 connector that are connected to the foldable solar panel 3.

[0040] Reference Figure 5 The storage bag 313 is used to store junction boxes and MC4 connectors, preventing dust and moisture from contaminating the MC4 connectors. In addition, the storage bag 313 can also hold some small parts.

[0041] In some embodiments, the side panel 13 is also provided with a USB interface and a first dust plug 131, the USB interface being electrically connected to the battery 2, and the first dust plug 131 being able to cover the USB interface.

[0042] Reference Figure 2 Users can charge mobile phones, tablets, and other electronic devices via the USB interface. During charging, electronic devices such as laptops can be placed on top of the top plate 11, improving the practicality and convenience of the outdoor emergency solar charger. The first dust plug 131 prevents moisture, dust, and other small particles from entering the USB interface, avoiding poor contact due to dust accumulation.

[0043] In some embodiments, the side plate 13 is also provided with a charging port and a second dust plug 132, the charging port and the battery 2 are electrically connected, and the second dust plug 132 can cover the charging port.

[0044] Reference Figure 2In situations where solar energy is insufficient for full charging or prolonged outdoor activities are required, users can charge the battery 2 via an external power source such as a household power outlet to ensure that there is always enough power available for use.
