Detailed implementation manners

[0039] The following further describes the present application in detail with reference to the Figure 1-8 accompanying drawings.

[0040] An embodiment of the present application discloses a foldable backpack for easy storage. Refer to Figure 1 and Figure 2 , the foldable backpack for easy storage includes a bag body 1, an inner lining bag 2, a first bottom plate 3, a second bottom plate 4 and a connection assembly 5.

[0041] As Figure 3 shown, the bag body 1 includes a bottom 11 and a wall 12, and the wall 12 is connected to the bottom 11 to form a load cavity 13 for the user to load items, realizing the storage function of the foldable backpack for easy storage.

[0042] As Figure 4 and Figure 5 shown, the inner lining bag 2 includes a first part 21, a second part 22 and a sewing part 23. Specifically, the inner lining bag 2 is formed by sewing two pieces of cloth, and the four sides of the two pieces of cloth are sewn to form a closed cavity. The sewing part 23 is arranged along the length direction of the inner lining bag 2, separating the inner lining bag 2 into a first part 21 and a second part 22. The cavity in the first part 21 is the first accommodation cavity 7, and the cavity in the second part 22 is the second accommodation cavity 8. The first bottom plate 3 is arranged in the first accommodation cavity 7, and the second bottom plate 4 is arranged in the second accommodation cavity 8. The side of the first part 21 of the inner lining bag 2 away from the second part 22 is connected to the bottom 11, so that the inner lining bag 2 can be laid above the bottom 11. When the user places loads such as books, pencil cases and water bottles into the load cavity 13, the foldable backpack for easy storage bears the load through the first bottom plate 3 and the second bottom plate 4 in the first accommodation cavity 7 and the second accommodation cavity 8, avoiding deformation of the bottom 11 of the foldable backpack for easy storage caused by overloading.

[0043] When the user needs to place the foldable backpack that is convenient for storage into relatively narrow spaces such as drawers, desk cavities, and suitcases, the user can flip the inner lining package 2 to reduce the support of the inner lining package 2 for the bottom 11, so that the bottom 11 can be bent or folded, reducing the area of the bottom 11. When the user places the foldable backpack that is convenient for storage into relatively narrow spaces such as drawers, desk cavities, and suitcases, the bottom 11 and the inner lining package 2 will not abut against the peripheral walls of the drawers, desk cavities, and suitcases, improving the problem that existing backpacks are inconvenient for storage.

[0044] As Figure 4 shown, the flat-laying area of the inner lining package 2 is smaller than the flat-laying area of the bottom 11. When the inner lining package 2 is laid flat on the bottom 11, the inner lining package 2 will not protrude from the bottom 11, so that the inner lining package 2 does not occupy extra space, and it is also convenient for the user to hold the side of the inner lining package 2 and flip the inner lining package 2, reducing the inconvenience that the user may bring when using the foldable backpack that is convenient for storage.

[0045] The ratio of the flat-laying area of the first part 21 to the flat-laying area of the second part 22 is 2:1. The thickness of the first bottom plate 3 is the same as the thickness of the second bottom plate 4. The length of the first bottom plate 3 is the same as the length of the second bottom plate 4. The ratio of the width of the first bottom plate 3 to the width of the second bottom plate 4 is 2:1, so that the first bottom plate 3 and the second bottom plate 4 can be accommodated in the first accommodation cavity 7 and the second accommodation cavity 8, preventing the first bottom plate 3 and the second bottom plate 4 from sliding or deflecting in the first accommodation cavity 7 and the second accommodation cavity 8, ensuring the stability of the use of the foldable backpack that is convenient for storage.

[0046] Both the first bottom plate 3 and the second bottom plate 4 are made of polypropylene plates. Polypropylene is a lightweight plastic. Using it to make the first bottom plate 3 and the second bottom plate 4 can reduce the overall weight of the foldable backpack that is convenient for storage and improve the convenience of carrying; polypropylene has good wear resistance and impact resistance, preventing the items inside the foldable backpack that is convenient for storage from being damaged due to the impact on the bottom 11 of the foldable backpack that is convenient for storage, ensuring the safety of the items inside the foldable backpack that is convenient for storage when storing various items.

[0047] Specifically, the user can adjust the distribution of the inner lining package 2 according to their specific needs. For example, when the items inside the foldable backpack that is convenient for storage do not fill the load cavity 13, or when the shapes of several items inside the foldable backpack that is convenient for storage are different, the user can flip the second part 22 to change the position of the second part 22, so that part of the bottom 11 can be bent or folded, enabling the user to place the foldable backpack that is convenient for storage into a relatively narrow space, improving the problem that existing backpacks are inconvenient for storage.

[0048] When there are no items placed in the foldable backpack that is convenient for storage, or when the user needs to compress the volume of the foldable backpack that is convenient for storage as much as possible to put it into a suitcase, the user can flip the lining bag 2 so that the first part 21 and the second part 22 are close to the wall portion 12, thereby further reducing the support of the lining bag 2 on the bottom 11. The user can further bend or fold the bottom 11 to compress the volume of the foldable backpack that is convenient for storage, so that the foldable backpack that is convenient for storage can be smoothly placed into relatively narrow spaces such as drawers, desk cavities, and suitcases, further improving the problem that the existing backpack is inconvenient to store and enhancing the versatility of the foldable backpack that is convenient for storage.

[0049] As Figure 3 shown, the connecting component 5 includes a first connecting piece 51 and a second connecting piece 52. Specifically, the first connecting component 5 is a magic tape. The first connecting piece 51 is arranged on the side of the bottom 11 close to the lining bag 2, and the side of the first connecting piece 51 away from the bottom 11 is the fuzzy surface; the second connecting piece 52 is arranged on the side of the second part 22 close to the bottom 11, and the side of the second connecting piece 52 away from the lining bag 2 is the hook surface; the first connecting piece 51 and the second connecting piece 52 are used in a matching manner so that the lining bag 2 and the bottom 11 can be connected through the first connecting piece 51 and the second connecting piece 52, preventing the relative positions of the lining bag 2 and the bottom 11 from changing due to the user's movement or the movement of items during the process of loading and using the foldable backpack that is convenient for storage, ensuring the fixation of the lining bag 2 during the loading and using process of the foldable backpack that is convenient for storage, and protecting the internal items from being damaged; the fuzzy surface and the hook surface can be connected multiple times, and the user does not need to accurately align the first connecting piece 51 and the second connecting piece 52. As long as there is partial contact between the fuzzy surface and the hook surface, the first connecting piece 51 and the second connecting piece 52 can be connected, simplifying the operation process and optimizing the user's experience.

[0050] A zipper 6 and a shoulder strap 9 are also arranged on the foldable backpack that is convenient for storage. The zipper 6 is arranged on the wall portion 12 for the user to open the zipper 6 and place items in the load cavity 13 of the foldable backpack that is convenient for storage, and close the load cavity 13 through the zipper 6 to prevent the items in the load cavity 13 from falling into the external environment when the user uses the foldable backpack that is convenient for storage; the user can carry the foldable backpack that is convenient for storage through the shoulder strap 9, thus freeing up both hands and reducing the burden on the user's hands.
