[0032] This utility model provides a backpack that can improve the comfort and flexibility of wearing the backpack, and facilitate the arrangement of the straps when the backpack is not in use, avoiding problems such as strap tangling or space occupation.

[0033] like Figures 1 to 7 As shown, this embodiment of the utility model provides a backpack 100, which includes a backpack body 110 and at least one shoulder strap 120. The back of the backpack body 110 has a contact surface 111 for contacting the human body. The contact surface 111 includes a first magnetic unit. The shoulder strap 120 is connected to the back of the backpack body 110 and includes a second magnetic unit. The first magnetic unit and the second magnetic unit can be magnetically attracted and connected to each other, so that the shoulder strap 120 can be attracted or separated from the contact surface 111. The outer contour of the shoulder strap 120 is arc-shaped, and the arc-shaped convex surface of the shoulder strap 120 is arranged in the direction of the contact surface 111.

[0034] This invention provides a first magnetic attraction unit on the contact surface 111 and a second magnetic attraction unit on the shoulder strap 120. The first and second magnetic attraction units are magnetically connected to each other, allowing the shoulder strap 120 to be attracted to or separated from the contact surface 111. This facilitates the organization of the shoulder strap 120 when the backpack 100 is not in use, preventing problems such as the shoulder strap 120 becoming tangled or taking up space. It also prevents the shoulder strap 120 from drooping and hooking onto other items, causing wear and tear on the surface of the backpack 100. The shoulder strap 120 and the backpack body 110 are magnetically and tightly connected, improving the aesthetic appearance of the backpack 100. By making the outer contour of the shoulder strap 120 curved, it naturally conforms to the physiological curvature of the human back and shoulders, improving the fit between the backpack 100 and the human body, enhancing comfort, and improving the user experience.

[0035] like Figure 1 as well as Figure 7 As shown, the backpack 100 includes two shoulder straps 120. The backpack 100 is a double-shoulder bag, and the curved convex surfaces of the two shoulder straps 120 are correspondingly arranged. It can be understood that the backpack 100 may also have only one shoulder strap 120, making it a single-shoulder backpack 100.

[0036] like Figure 2 As shown, the contact surface 111 has a protruding first functional area 1113, which is arranged vertically along the backpack body 110. A first magnetic unit is embedded within the first functional area 1113, and the first functional area 1113 is covered with a breathable fabric. Preferably, the first functional area 1113 is filled with a cushioning material, such as memory foam, sponge, or activated carbon fiber composite layer, which helps support the user's back. This utility model's technical solution, by covering the first functional area 1113 with a breathable fabric, promotes air circulation and reduces stuffiness when the backpack body 110 is in prolonged contact with the user's back. It is understood that breathable fabric can also be provided on the shoulder straps 120 to enhance breathability. Specifically, the breathable fabric has honeycomb-shaped ventilation holes to improve breathability of the back and shoulders. The breathable fabric can be knitted fabric, elastic non-woven fabric, etc.

[0037] like Figure 2As shown, the contact surface 111 also has a protruding second functional area 1114, which is located at the bottom of the first functional area 1113. The second functional area 1114 contains storage space. This utility model's technical solution, by providing storage space in the second functional area 1114, facilitates the expansion of the backpack 100's storage capacity. It can be used to store small items such as tissues and cards, making it convenient for users and improving the backpack 100's practicality. Preferably, the storage space in the second functional area 1114 can be enclosed with a zipper or snaps to prevent items from being lost. Preferably, the width of the second functional area 1114 is greater than that of the first functional area 1113 to facilitate storage.

[0038] Preferably, the surfaces of the first functional area 1113 and the second functional area 1114 are also provided with anti-slip textures to prevent the backpack 100 from sliding when carried.

[0039] Preferably, the strap 120 is made of an elastic material, such as elastic nylon, so that the strap 120 has a certain elastic deformation capability and can better fit the dynamic changes of the human back and shoulders.

[0040] like Figures 4 to 5 As shown, the first functional area 1113 is provided with multiple first magnetic units, which are arranged sequentially and at intervals along the extension direction of the first functional area 1113. The shoulder strap 120 is provided with multiple second magnetic units, which are arranged along the extension direction of the shoulder strap 120.
