Specific embodiments

[0027] Next, the technical solutions in the embodiments of the present utility model will be described clearly and completely. 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.

[0028] Embodiment: A double-shoulder backpack that is easy to fold and store, such as Figures 1-5 and Figure 7As shown in the figure, it includes a main bag 1, shoulder straps 2, connecting straps 3, cushion pads 4, secondary bags 5, outer bags 6, storage bags 7, zippers 8, ball catches 10 and springs 11. The main bag 1 serves as the main storage space of the entire backpack. Shoulder straps 2 are sewn on both sides of the upper part of the main bag 1. Connecting straps 3 are sewn at the bottoms of both shoulder straps 2. The lower part of the connecting strap 3 is bent. Cushion pads 4 are sewn on both edges of the rear side of the lower part of the main bag 1. The lower part of the connecting strap 3 slides through the cushion pads 4. A secondary bag 5 is provided on the front side of the upper part of the main bag 1, providing additional storage space for convenient and quick access to small items. An outer bag 6 is provided on the front side of the lower part of the main bag 1, also increasing the storage space, usually used to store easily accessible items. Hidden edge openings are provided on the upper parts of the main bag 1, secondary bag 5 and outer bag 6, and this hidden edge is used for an external chain assembly. A folding groove is opened in the middle of the main bag 1, and the height of this folding groove is flush with the upper end of the storage bag 7. Storage bags 7 are sewn on both sides of the middle of the main bag 1, which can not only store items but also be used for the overall folding and storage of the backpack. Zippers 8 are provided on the outward sides of both storage bags 7 to ensure that items do not fall out safely and also help with the folding and storage of the backpack. Equally spaced card holes 9 are opened on both connecting straps 3. The card holes 9 are used in conjunction with the ball catches 10 to allow the user to adjust the length of the connecting strap 3. The ball catches 10 slide into the card holes 9. Ball catches 10 are slidably arranged inside the cushion pads 4 on the opposite sides. Springs 11 are provided between the two ball catches 10 and the inner walls of the cushion pads 4. The springs 11 provide elastic support to help the backpack better adapt to different load conditions and ensure the stability of the shoulder straps 2. All the components connected with the main bag 1 as the carrier will combine to form the overall backpack. The overall backpack is folded and stored through the storage bag 7 and zipper 8 on one side, and placed through the storage bag 7 and zipper 8 on the other side.

[0029] As Figure 1 , Figure 5 and Figure 7 shown in the figure, it also includes a back cushion soft board 12. The back cushion soft board 12 is adhesively attached to the rear part of the main bag 1 in a covering manner. There is a certain distance interval between the front side of the back cushion soft board 12 and the rear side of the main bag 1, providing a comfortable feeling when carrying and reducing the back pressure. A number of equally spaced ventilation holes 14 are symmetrically opened on both sides inside the back cushion soft board 12 to help with ventilation and reduce the stuffy feeling when carrying.

[0030] As Figure 6 shown in the figure, it also includes a soft rubber elastic board 13. A soft rubber elastic board 13 is arranged between the interval of the back cushion and the main bag 1. The soft rubber elastic board 13 is an overall hollow interval structural board, and the hollow structure of the hollow interval structural board is arranged in a continuous and equidistant manner, which can further improve the carrying comfort and contribute to ventilation, reducing the accumulation of sweat on the back.

[0031] As Figure 1 and Figure 5As shown in the figure, it also includes an exhaust gasket 15. The exhaust gaskets 15 are adhesively attached to both sides of the upper part of the secondary bag 5, which is used to increase breathability and can discharge the gas in the secondary bag 5 accordingly.

[0032] When the backpack needs to be folded and stored as a whole, first open all the zippers 8 of the backpack, take out all the internal items to ensure there is no obstruction during folding. Then close all the zippers 8 on the main bag 1, secondary bag 5, and outer bag 6 to protect the interior from dust or foreign objects entering and ensure that all parts fit tightly during folding. Next, gently fold the backpack backward along the pre-designed folding groove in the middle of the main bag 1. This groove makes the folding easier and smoother. The gas in the secondary bag 5 will be discharged from the exhaust gasket 15, making the folding process easier. After folding along the groove, fold it in half again, and pay attention to keeping the backpack flat during folding to avoid unnecessary wrinkles or twists. The folded backpack body is then inserted into the opening of the storage bag 7 on one side, ensuring that the backpack body is neatly placed inside without being squeezed. Moreover, the position of the connecting strap 3 can be adjusted according to the thickness of the backpack body to make it close to the inner wall of the storage bag 7, reducing the extra space. Then, use the ball catch 10 on the connecting strap 3 to cooperate with the card hole 9 to adjust and fix the position of the connecting strap 3 to ensure the stability of the backpack body inside the storage bag 7. The design of the spring 11 enables the ball catch 10 to flexibly enter and exit the card hole 9, which is not only convenient for adjustment but also ensures the stability of the connecting strap 3. Open the storage bag 7 on the other side and insert the backpack body that has been stored in the storage bag 7 on the previous side into it to make it more compact. Use the zipper 8 on the storage bag 7 again to fix the backpack body in the folded state to ensure that it will not easily come apart. After completing the above steps, the backpack has been compactly stored in the storage bag 7, which completely changes and significantly reduces the space occupied by the backpack. When the backpack needs to be unfolded, first unzip the zipper 8 on the storage bag 7, take it out from the storage bag 7, and then unfold the backpack body to release it. Unfold the backpack body step by step in the reverse order of folding. The length of the connecting strap 3 will be adjusted as needed. When adjusting, just pull the connecting strap 3. When the connecting strap 3 is pulled, it will come into contact with the ball catch 10, causing the ball catch 10 to contact the closed end face of the connecting strap 3 without the card hole 9. At this time, the ball catch 10 will compress the spring 11, causing it to shorten and deform. After the ball catch 10 contacts the next card hole 9 on the connecting strap 3, the adjustment is completed. When wearing the main bag 1, the user's back will first come into contact with the back cushion soft board 12 on the back side of the main bag 1. The ventilation holes 14 on the back cushion soft board 12 help improve the comfort during carrying and enhance breathability. The hollow structures of the soft rubber elastic plates 13 are arranged continuously and at equal intervals, which not only provides better elastic support but also helps maintain the shape of the backpack. Moreover, the hollow structures of the soft rubber elastic plates 13 have a certain heat insulation and sweat discharge effect, which can cooperate with the back cushion soft board 12 to effectively buffer the back pressure and improve the comfort during carrying.
