Specifically, the part of the upper connecting part 2 located on the upper part of the bag body 1 is symmetrically distributed to the waistline position, extends upward along the human spine to the position close to the scapula, deviates from the spine and extends obliquely upward along the scapular line to the lower connecting part 3. This design enables the upper connecting part 2 to closely fit the natural contour of the back of the human body, providing stable and comfortable carrying experience.

[0039] The upper connecting part 2 is made of breathable cushioning material, such as mesh nylon cloth combined with memory foam layer. The upper connecting part 2 made of breathable cushioning material not only increases the comfort of the back, but also provides the necessary cushioning when carrying heavy objects, reducing the direct impact of the backpack on the back, and its breathability also helps to reduce the accumulation of sweat on the back, keeping the back dry.

[0040] The part of the upper connecting part 2 located on the upper part of the bag body 1 is connected to the bag body 1 only on the side close to the human spine. Specifically, as shown in Fig. 2 , the upper connecting part 2 is connected to the bag body 1 at the waistline position and only on the side close to the human spine along the spine direction to the scapular line. At the same time, the side of the upper connecting part 2 away from the human spine forms a semi-open structure with the bag body 1, which can move with the shaking of the lower connecting part 3. This structure can fit the back curve of different users, so that the upper connecting part 2 can closely fit the back of the human body, especially in the key support area around the scapula and spine, thereby providing stable support and comfortable carrying experience. In this embodiment, the upper connecting part 2 is connected to the bag body 1 by sewing, as shown in Fig. 2The sewing thread 4 is shown. The sewing connection mode ensures the firmness between the upper connecting part 2 and the bag body 1, and makes the double-shoulder bag structure stable and reliable.

[0041] The airflow channel 5 corresponding to the human spine is formed between the two upper connecting parts 2, which is designed to effectively promote the air flow of the back, reduce the hot feeling of the back, and enhance the comfort of the user when carrying the double-shoulder bag for a long time.

[0042] As shown in Fig. 1 and Fig. 2 The lower connecting part 3 includes a first adjusting buckle 6, a first adjusting belt 7, a second adjusting buckle 8, and a second adjusting belt 9.

[0043] The first adjusting buckle 6 is located near the upper part of the bag body 1, and the first adjusting buckle 6 is adjustably connected with the bag body 1. Specifically, the first adjusting buckle 6 is fixed with the bag body 1 by the first adjusting belt 7, and through the first adjusting buckle 6 and the first adjusting belt 7, the user can adjust the relative position of the lower connecting part 3 and the bag body 1 according to the thickness of his own shoulders, which improves the stability of the double-shoulder bag and reduces the shaking caused by the gap between the double-shoulder bag and the back.

[0044] The second adjusting buckle 8 is adjustably connected with the two lower connecting parts 3 at the chest position. Specifically, the second adjusting buckle 8 is adjustably connected with the two lower connecting parts 3 by the second adjusting belt 9. Specifically, the second adjusting belt 9 is divided into two auxiliary belts, and the two auxiliary belts are adjustably connected to the two lower connecting parts 3 at one end and connected to the second adjusting belt 9 at the other end. The second adjusting buckle 8 is a chest buckle, which can adopt a male buckle and a female buckle that cooperate with each other. The user can quickly connect the male buckle and the female buckle to complete the connection of the second adjusting belt 9. The second adjusting buckle 8 and the second adjusting belt 9 can effectively distribute the direct pressure of the double-shoulder bag on the shoulders, enhance the stability of the back, prevent the shoulder straps from slipping, and reduce the vibration feeling when carrying, and protect the spine. At the same time, the balanced force distribution avoids the excessive pressure on the single shoulder, and prevents the health problems caused by long-term wearing of high and low shoulders.

[0045] The waistband 11 assembly includes the elastic waist pad 10 and the waistband 11. The elastic waist pad 10 is located below the upper connecting part 2 corresponding to the waist of the human body and is fixedly connected with the bag body 1, and forms a containing channel perpendicular to the extension direction of the human body with the bag body 1. The waistband 11 passes through the containing channel and extends to the left and right sides of the bag body 1 and is suitable for being buckled on the front side of the human body. Specifically, the elastic waist pad 10 can be made of polyethylene material with elasticity. The elastic waist pad 10 made of polyethylene material not only has good elasticity, but also can fit the waist curve of different users and provide comfortable support. The waistband 11 assembly additionally provided with the elastic waist pad 10 and the waistband 11 optimizes the stress distribution, effectively reduces the burden on the shoulders and the back, and can automatically adjust in the dynamic change of the backpack to keep close fitting with the waist and improve the stability and comfort of the carrying. It is especially suitable for long-term carrying or outdoor activities. At the same time, the elastic waist pad 10 increases the contact area and provides cushioning, effectively preventing the impact of the swinging backpack on the back of the waist.

[0046] The waistband 11 and the bag body 1 are connected in a detachable manner, such as magic tape or quick release buckle, which is convenient for users to use flexibly according to needs. The detachable waistband 11 design increases the flexibility of the backpack, and users can choose to use or not to use the waistband 11 according to needs to adapt to different use scenarios and personal preferences. Users can adjust the configuration of the backpack according to actual needs, such as choosing no waistband 11 mode in leisure occasions to keep light; when long-term carrying or carrying heavy objects are needed, the waistband 11 can be installed to enhance the stability and comfort of the carrying.

[0047] Through the above second adjusting buckle 8 and waistband 11 assembly, the stress on the shoulders can be effectively reduced.

[0048] In this embodiment, the shoulder strap integrates the upper connecting part 2 and the lower connecting part 3 to form a shoulder-carrying integrated carrying system. Specifically, the design of the upper connecting part 2 closely follows the principle of human engineering. The part of the upper connecting part 2 located on the upper part of the bag body 1 is connected with the bag body 1 only on the side close to the human spine, forming a semi-open fitting structure, which can more flexibly adapt to the shoulder and back angles of different users and the changes in the shoulder curvature in different activity states (such as static standing, leisure walking, fast walking, and even running). This dynamic adaptability increases the stress area of the shoulders, so that the weight of the backpack can be more evenly distributed to the entire shoulder and back, reducing the stress burden on a single part, effectively relieving the shoulder fatigue and discomfort caused by long-term carrying of the backpack, ensuring the stability and comfort of the backpack during wearing, and effectively avoiding the inconvenience caused by the swinging or displacement of the backpack.
