[0002] In daily life and extensive outdoor activities, backpacks, as indispensable carrying tools, play an extremely important role, and their application scenarios cover people's travel, tourism, hiking, school commuting and work travel and other aspects. However, the current backpack products on the market generally face the challenge of single function, mainly focusing on being a simple storage container, that is, focusing on improving the loading capacity and portability, but ignoring the diversified needs of users in actual use.

[0003] Specifically, users often face inconvenience due to the lack of suitable seats in various scenarios, such as short breaks after long journeys, waiting periods during outdoor camping, or temporary stops in public places. The design of traditional backpacks fails to foresee and meet this actual need, making users have to find other alternatives when they need to rest, which is neither convenient nor efficient.

[0004] In addition, as the weight of the loaded items in the backpack increases, the physiological burden brought by long-term carrying also becomes increasingly significant. The continuous pressure on the shoulders, back and neck not only causes muscle fatigue and soreness, but also may cause long-term physical health problems, which is particularly serious for user groups who frequently travel long distances or go on outdoor adventures. Although some backpack products on the market have tried to reduce the carrying pressure by optimizing the design of the straps, introducing ergonomic principles or adding cushioning materials, these improvements have not completely changed the essence of the single function of backpacks, nor have they effectively solved the limitation that backpacks cannot be used as rest seats.

[0005] In summary, the limitations of existing backpack products in functional design have made it difficult to meet the growing diversified needs of users. Therefore, developing a new type of backpack product that can not only meet basic storage needs, but also be converted into a portable seat for use or used as a luggage case for dragging and walking, completely relieving the body weight and effectively relieving the fatigue of carrying, has become a technical problem that needs to be solved in the current backpack design field.
