[0028] The detailed features and advantages of this patent are described in detail in the specific implementation method below, and the content is sufficient to enable any technical personnel in this field to understand the technical content of this patent and implement it accordingly. According to the description, claims and drawings disclosed in this specification, technical personnel in this field can easily understand the relevant purposes and advantages of this patent.

[0029] In order to make the purpose, technical solutions and advantages of this patent clearer, the implementation method of this patent will be further described in detail below in conjunction with the accompanying drawings.

[0030] like Figure 1 As shown in the top view of the three-dimensional schematic diagram of a backpack with a light carrying system in this embodiment, it should be noted that the "back" of the bag body here refers to the side that contacts the human body when the backpack is carried. The backpack includes a bag body 100 and a carrying system 200. The carrying system 200 is arranged behind the backpack body and is cut and formed integrally with the backpack body. The carrying system 200 contacts a large area of ​​the back of the human body when carried. The adjustable connection between the carrying system 200 and the bag body 100 can reduce the force of the bag body 100 on the human shoulder.

[0031] The bag body 100 includes a first restraint belt 110 and a first adjustment buckle 120. The first restraint belt 110 is slender and has a first adjustment buckle 120 in the middle of the first restraint belt 110. The carrying system 200 includes an upper shoulder strap 210, a lower shoulder strap 220, a second restraint belt 230, a second adjustment buckle 240 and a back plate 250. The shoulder straps are symmetrically arranged on both sides of the back plate 250. Among them, the upper end of the upper shoulder strap 210 is provided with a second restraint belt 230, which is used to match and connect the first restraint belt 110 arranged on the top of the back of the bag body 100, so as to adjust the retraction and release of the bag body 100 relative to the human body. At the same time, the bottom of the upper shoulder strap 210 is provided with a second adjustment buckle 240, which is used to realize the corresponding connection of the upper and lower shoulder straps 220 and realize the adjustment of the overall length of the shoulder straps. Correspondingly, the other ends of the two lower shoulder straps 220 are respectively matched and connected to the bottom sides of the back of the bag body 100. In actual setting, the second adjustment buckle 240 is fixed to the bottom of the upper shoulder strap 210, so that one end of the lower shoulder strap 220 can be matched and passed through the second adjustment buckle 240 to realize the connection setting of the shoulder strap.

[0032] The second restraint belt 230 is set at the position of the upper shoulder strap 210 near the top of the back plate 250, one end of which is fixed to the outside of the upper shoulder strap 210 (the side of the shoulder strap facing away from the human body when the backpack is carried), and the other end is set freely to match the first adjustment buckle 120. Correspondingly, the first adjustment buckle 120 is connected to the top of the back of the bag body 100 through the first restraint belt 110; it can be understood that in actual settings, the first adjustment buckle 120 is divided into two on both sides of the top of the back of the bag body 100, which are respectively used to achieve matching with the two upper shoulder straps 210, and are combined into a Figure 2 The connection form shown in .

[0033] The connection point between the upper shoulder strap 210 and the back plate 250 is a suture point p. Figure 3 As shown, according to the principle of ergonomics, the stitching point p in this embodiment is lower than that of an ordinary backpack. In the carrying state, the upper shoulder strap 210 and the lower shoulder strap 220 are fixedly enclosed to form an arc, wherein the upper shoulder strap 210 acts on the back and shoulders, and the first restraint belt 110 and the second restraint belt 230 provide a certain stretching force to the upper shoulder strap 210 under the fixed connection of the first adjustment buckle 120, thereby reducing the force of the bag body 100 on the human body. The stitching point p is set at the end of the shoulder blade force point on the back of the human body. Specifically, the distance between point P and the upper end of the bag body 100 is d, and the overall length of the bag body 100 is D, d / D=15%. Without adjusting the first adjustment buckle 120 and the second adjustment buckle 240, the setting of the stitching point p makes the back of the human body, especially the shoulder blade force point, move downward as a whole, that is, the center of gravity of the human backpack moves downward as a whole, and the carrying system 200 at this time forms a "water drop-shaped" carrying shape from the side as shown in the figure. The "water drop-shaped" carrying shape reduces the pulling of the shoulder straps and evenly distributes the force of the backpack on the human body, which can reduce carrying pressure and improve carrying comfort.

[0034] In the description of the patent, it is necessary to understand that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing this patent and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on this patent.
