[0001] This utility model belongs to the field of solar energy application equipment technology, specifically an adjustable bracket solar folding bag. Background Technology

[0002] With the continuous development of new energy technologies, solar energy, as a clean and renewable energy source, is widely used in various fields. In scenarios such as outdoor travel and emergency rescue, solar-powered folding bags are becoming an increasingly popular choice due to their portability and energy supply capabilities.

[0003] In current technology, solar panels are modularly integrated into the outer layer of a backpack, using hinges or high-strength nylon folding panels to unfold when in use and fold away for storage when not in use, thus protecting the panels.

[0004] However, when using existing devices, most of the solar folding bags on the market only focus on portability after folding, but neglect the angle adjustment function when unfolded. Since the angle of illumination varies in different scenarios, the fixed-angle solar panel cannot always maintain the best light-receiving posture, resulting in low solar energy conversion efficiency. Therefore, to address the above problems, an adjustable bracket solar folding bag is proposed. Utility Model Content

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Specific implementation examples are given below.

[0020] Please see Figure 1 - Figure 4This utility model provides a bracket-adjustable solar folding bag, including a folding bag body 10. Solar folding plates 11 are mounted on the body 10, and folding plates 12 are fixedly connected between the solar folding plates 11. First extension plates 21 are fixedly connected to the upper sides of the back of each solar folding plate 11, and first fixed shafts 22 are fixedly connected between the first extension plates 21. Support plates 23 are rotatably connected to the first fixed shafts 22. When the solar folding plate 11 is folded by the folding plates 12, the support plates 23 are misaligned. During operation, the surface of the solar folding plate 11 integrates solar power generation components, converting sunlight into electrical energy. Multiple sets of solar folding plates 11 are connected by folding plates 12. When unfolded, they can expand the light-receiving area and improve power generation efficiency; when folded, they reduce the volume. The folding plates 12 are the connecting link of the solar folding plates 11, fixing multiple sets of solar folding plates 11 into a whole to ensure structural stability; on the other hand, they have bendable characteristics, allowing for the folding of solar panels. The unfolding and folding of plate 11 provides crucial support and is the core component for realizing the folding function of the equipment. The first extension plate 21 is fixed on both sides of the upper back of the solar panel 11, which can stably support the first fixed shaft 22 and avoid the instability or wear of components caused by the first fixed shaft 22 directly contacting the solar panel 11. It provides a reliable installation foundation for the rotation of the support plate 23. The first fixed shaft 22, by being fixed to the first extension plate 21, provides a fulcrum for the support plate 23 to rotate around the shaft. Its fixed characteristic ensures that the support plate 23 can rotate stably around it, thereby realizing the adjustment of the tilt angle of the solar panel 11. When the support plate 23 rotates around the first fixed shaft 22, it can change from the storage state to the support state. After unfolding, it can support the lower end of the solar panel 11, so that the solar panel 11 is tilted. At the same time, when the solar panel 11 is folded, its staggered design can avoid the multiple sets of support plates 23 from jamming each other, ensuring a smooth folding process and solving the problem of interference in the folding of traditional brackets.

[0021] Furthermore, such as Figure 2 and Figure 3 As shown, a second extension plate 24 is fixedly connected to both sides of the lower back of the solar panel 11. A second fixed shaft 25 is fixedly connected between the second extension plates 24. During operation, the second extension plates 24 function similarly to the first extension plate 21, serving as mounting brackets for the second fixed shaft 25. They are fixed to both sides of the lower back of the solar panel 11, stabilizing the second fixed shaft 25 and providing a reliable fulcrum for the rotation of the positioning plate 26. This prevents the positioning plate 26 from failing to maintain its angle due to instability. The second fixed shaft 25 provides a fulcrum for the positioning plate 26 to rotate around the shaft, enabling the positioning plate 26 to switch between a support positioning state and a storage state. This is the key to the positioning plate 26 achieving multi-functional switching.

[0022] Furthermore, such as Figure 3As shown, a positioning plate 26 is rotatably connected to the second fixed shaft 25. The positioning plate 26 rotates around the second fixed shaft 25. A placement groove 27 is provided on the inner side of the positioning plate 26, and the support plate 23 is located in the placement groove 27. During operation, the positioning plate 26 accommodates the support plate 23 through the placement groove 27 on its inner side, preventing the support plate 23 from shaking. On the other hand, it cooperates with the through hole 28 to insert the support plate 23 into the through hole 28 at different positions, thereby fixing the tilt angle of the solar panel 11, adapting to different light directions, and ensuring efficient light reception. At the same time, when folded, it can rotate with the second fixed shaft 25 to fit the solar panel 11 without occupying extra space. The placement groove 27 can limit the support plate 23 to the inner side of the positioning plate 26, preventing the support plate 23 from shifting or shaking during support or storage, ensuring the stable cooperation between the support plate 23 and the positioning plate 26, and thus ensuring the precise fixing of the tilt angle of the solar panel 11.

[0023] Furthermore, such as Figure 3 As shown, the positioning plate 26 has through holes 28, and there are multiple sets of through holes 28. The cross-section of the through holes 28 is larger than that of the support plate 23. During operation, the design of multiple sets of through holes 28 provides different insertion positions for the support plate 23. When the support plate 23 is inserted into different through holes 28, the tilt angle of the solar panel 11 will change accordingly, realizing the function of multi-angle adaptation to sunlight, and solving the problems of fixed angle and low power generation efficiency of traditional solar panels.

[0024] Furthermore, such as Figure 2 and Figure 3 As shown, a magnetic block 265 is fixedly connected to the end of the positioning plate 26, and a magnetic plate 33 is fixedly connected to the back of the solar panel 11. The magnetic plate 33 and the magnetic block 265 are positioned correspondingly. An installation hole 29 is provided on the inner side of the bottom of the positioning plate 26. When working, the magnetic block 265 and the magnetic plate 33 are positioned correspondingly and magnetically attracted. When the device is folded, the positioning plate 26 rotates to fit against the back of the solar panel 11, and the magnetic block 265 and the magnetic plate 33 are attracted and fixed, which can stably hold the positioning plate 26 and the support plate 23, preventing the parts from shaking or loosening after folding, and improving portability.

[0025] Furthermore, such as Figure 2 and Figure 5As shown, a storage box 30 is fixedly connected to the back of the solar panel 11. A folding crossbar 31 is magnetically attached inside the storage box 30. During operation, the storage box 30 provides dedicated storage space for the folding crossbar 31, preventing it from being lost. Furthermore, the magnetic attachment secures the folding crossbar 31, eliminating the need for additional operations during retrieval and storage, thus improving ease of use. When unfolded, the folding crossbar 31 is inserted into the mounting hole 29, providing lateral support to the main body 10 of the folding package. This prevents the solar panel 11 from deforming or tipping over due to lateral force after unfolding, enhancing the stability of the equipment during outdoor use. The folded design is compact and can be directly placed into the storage box 30 without taking up extra space.

[0026] Furthermore, such as Figure 5 As shown, an elastic rope 32 is fixedly connected inside the folding crossbar 31. The folding crossbar 31 is provided with three sections. The outer surfaces of both ends of the middle section are provided with threaded rings, and the inner surfaces of the two end sections are provided with threaded rings. The elastic rope 32 passes through the middle section of the folding crossbar 31 and is fixedly connected inside the two end sections. During operation, the elastic rope 32 passes through the middle section of the folding crossbar 31 and is fixed inside the two end sections. On the one hand, it can connect the three sections of the folding crossbar 31 in series to avoid the loss of the two end sections after disassembly. On the other hand, it has elasticity, which can assist in the unfolding and folding of the folding crossbar 31 and improve the convenience of operation.

[0027] Furthermore, such as Figure 2 As shown, the positioning plate has an installation hole on the inner side of its bottom. The opening cross section of the installation hole is larger than the cross section of the folding crossbar. When in operation, the installation hole 29 can be used to insert the folding crossbar 31 into the solar panel 11 when it is opened, so as to provide lateral support for the solar panel 11.

[0028] Working principle: When in use, unfold the solar panel 11 and unfold the positioning plate 26 outward. The top of the positioning plate 26 rotates around the second fixed axis 25. Next, unfold the support plate 23 outward and rotate the support plate 23 around the first fixed axis 22. Combined with the angle of illumination, insert the support plate 23 into the corresponding through hole 28 to support the solar panel 11. Take the folding crossbar 31 out of the placement box 30. After unfolding the threaded connection of the folding crossbar 31, insert it into the mounting hole 29 to provide lateral support for the solar panel 11. This completes the unfolding of the solar panel 11. After use, fold the folding crossbar 31 and put it into the placement box 30. Remove the support plate 23 from the through hole 28. The support plate 23 rotates around the first fixed axis 22, and the positioning plate 26 rotates around the second fixed axis 25. The support plate 23 is placed in the placement slot 27. The magnetic block 265 is attracted to the magnetic plate 33 to fix the positioning plate 26. Finally, fold the solar panel 11 in half and store it.
