DETAILED DESCRIPTION

[0023] The technical solutions in the new type will be described clearly and completely below in combination with the drawings in the embodiments of the new type. Obviously, the described embodiments are only a part of the embodiments of the new type, not all the embodiments. Based on the embodiments in the new type, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the new type.

[0024] The following embodiments can be understood as explaining the partial structure of the new type separately, or as explaining the larger range of structure of the new type through the combination of multiple embodiments.

[0025] Embodiment 1

[0026] A multi-functional modular backpack, such as Figures 1-3 As shown, the backpack includes an upper bag body 1, a lower bag body 2, and a hanging bag 3. The lower bag body 2 is located below the upper bag body 1. The upper bag body 1 and the lower bag body 2 are detachably connected by an adjustable-length connector, which allows for adjustment of the distance between the upper and lower bag bodies according to the size of the user. Furthermore, the position of the upper and lower bag bodies can be adjusted to customize the contact area between the backpack and the user, meeting individual comfort needs. The front of the upper bag body 1 and the lower bag body 2 is connected by the hanging bag 3. The hanging bag 3 is detachably connected to the front of both the upper bag body 1 and the lower bag body 2. An adjustable-length connector also connects the hanging bag 3 to the upper bag body 1, allowing the hanging bag 3 to be adjusted in height relative to the front of the upper bag body 1 and the lower bag body 2. The hanging bag 3 serves to connect the upper bag body 1 and the lower bag body 2, while also contributing to the aesthetics, making the backpack appear as a single, integrated structure. Additionally, the hanging bag 3 can be adjusted vertically to accommodate adjustments in the distance between the upper bag body 1 and the lower bag body 2.

[0027] Example 2

[0028] like Figures 1-3 As shown, the upper bag body 1 has detachable shoulder straps on both sides of its back. Each shoulder strap includes a shoulder strap 4 and an adjustable length connecting strap 5 attached to the lower end of the shoulder strap 4. Each end of the shoulder strap 4 has a buckle 9. The upper and lower ends of both sides of the upper bag body 1 have hanging loops 6, and the ends of the shoulder straps are detachably connected to the hanging loops 6 via the buckles 9. The lower bag body 2 also has hanging loops (such as...) on its front ends at both sides. Figure 1 As shown in the figure (not marked), the buckle 9 at the lower end of the shoulder strap is used in conjunction with the hanging loop of the lower bag body 2.

[0029] In this embodiment, the adjustable length connecting strap uses a common connecting strap structure in the backpack industry, and the buckle is also a common structure, which is an elliptical ring with an open end. A rotating arm is hinged to the open end via a torsion spring. The hanging ring 6 can squeeze the rotating arm into the buckle. After insertion, the rotating arm returns to its original position due to the elastic force of the torsion spring and seals the opening. This new invention also provides hanging rings on both sides of the lower bag body. Therefore, the user can connect the lower end of the shoulder strap to the hanging ring on the lower back of the upper bag body, or to the hanging rings on both sides of the lower bag body as needed. The latter can create a mutual restraint force pattern between the upper and lower bag bodies. That is, the lower bag body pulls the upper bag body upward through the shoulder strap, reducing the weight of the upper bag body, while the upper bag body pulls the lower bag body forward through the shoulder strap, causing the lower bag body to fit snugly against the waist, achieving a shaping effect. It should be noted that the detachable connection method between the shoulder strap and the upper and lower bag bodies in this invention can be selected from other buckle forms disclosed in the prior art that can achieve detachable functionality.

[0030] Example 3

[0031] likeFigure 1 As shown, the lower body 2 has lumbar support pads 7 on both sides of its back, and each of the two lumbar support pads 7 has a strap 8 sewn on it. The lower body 2 is tied around the waist by the strap 8.

[0032] Example 4

[0033] like Figures 1-3 As shown, the back of the hanging bag 3 and the front of the lower bag body 2 are detachably connected by a magnetic attraction mechanism. The magnetic connection can be achieved using various forms disclosed in existing technologies.

[0034] Example 5

[0035] like Figures 1-3 As shown, the magnetic attraction mechanism includes magnetic metal strips 15 arranged longitudinally on both sides of the front of the lower bag body 2, and magnetic buckles 31 arranged on the back of the hanging bag 3. The magnetic buckles 31 are used in conjunction with the magnetic metal strips 15, and the magnetic metal strips 15 and magnetic buckles 31 are respectively sewn onto the lower bag body 2 or the hanging bag 3.

[0036] In this embodiment, when it is necessary to adjust the height of the bag, the magnetic buckle can be moved up and down along the magnetic metal strip and then attached and fixed after the height is adjusted.

[0037] Example 6

[0038] like Figures 1-3 As shown, the adjustable length connector 10 includes a male buckle 102 and a female buckle 103. A connecting strap 101 is connected to the male buckle 102. The length of the connecting strap 101 is adjusted by adjusting the locking position of the connecting strap 101 and the male buckle 102. The male buckle 102 and the female buckle 103 are used in conjunction. The adjustable length connector 10 provided in this embodiment is prior art; any aspects not described are addressed using existing solutions.

[0039] like Figure 1 As shown, the sides of the upper bag body 1 and the lower bag body 2 are connected by an adjustable length connector 10. One end of the connecting strap 101 is sewn to the outer surface of the upper bag body 1, and the other end is connected to the male buckle 102. One end of the female buckle 103 is sewn to the outer surface of the lower bag body 2.

[0040] like Figure 2 As shown, the upper bag body 1 includes a first storage compartment 12 connected to the shoulder strap, a second storage compartment 13 sewn onto the side of the first storage compartment 12 away from the shoulder strap, a third storage compartment 17 sewn onto the upper part of the side of the second storage compartment 13 away from the shoulder strap, and a cover curtain 14 sewn onto the lower end of the third storage compartment 17. The lower end of the cover curtain 14 is connected to the front of the hanging bag 3 by an adjustable length connector 10.

[0041] Example 7

[0042] In the embodiment, the male plug buckle 102 of the hanging bag 3 is connected with the front of the hanging bag 3 through the connecting belt 101, the male plug buckle 102 of the hanging bag 3 has two, and the two male plug buckles 102 of the hanging bag 3 are used in cooperation with the female plug buckles 103 on both sides of the lower bag body 2; the inner sides of the front and back walls of the hanging bag are respectively provided with elastic filling layers. That is to say, when the upper bag body is not needed to be used, the lower bag body and the hanging bag can be disassembled, the male plug buckle of the hanging bag is inserted into the female plug buckle of the corresponding lower bag body, and only the hanging bag and the lower bag body are carried out.

[0043] In use, the backpack can be disassembled into the upper bag body, the lower bag body and the hanging bag, and is respectively used to contain different amounts of objects, one or a combination of two of them is selected according to needs to go out. The shoulder strap can be used to connect the upper bag body, and can also connect the upper bag body and the lower bag body at the same time, after the shoulder strap is disassembled, the upper bag body can be used as a handbag, the two ends of the shoulder strap can be connected with the hanging rings on both sides of the lower bag body, so that the lower bag body is used as a crossbody bag. The lower bag body can be used as a waist bag alone, the hanging bag can be used as a tote bag or a file bag alone, and at the same time, the hanging bag can also be used as a seat cushion. The commonly used use mode of the backpack is that three bags are combined into an integral structure, the appearance is beautiful, the use is convenient, the stress part can be adjusted, the human comfort needs are met, and the shaping effect is also achieved.
