Fig. 1 is a schematic structural view of the backpack of the present invention;
fig. 2 is a schematic structural view of the support structure in the backpack of the present invention.
In the drawings, the components represented by the respective reference numerals are listed below:
1. a backpack body; 21. a vertical plate support; 22. supporting by a transverse plate; 23. and (4) bracing.
Detailed Description
The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.
Example (b): as shown in fig. 1 and 2, the backpack of the present embodiment includes a backpack body 1 and a supporting structure, the supporting structure includes a vertical plate support 21, a horizontal plate support 22 and an inclined strut 23, the vertical plate support 21 is disposed in an interlayer of a back surface layer of the backpack body 1, the horizontal plate support 22 is horizontally disposed at a front side of the vertical plate support 21 and is disposed at a position near a bottom inside the backpack body 1, a periphery of the horizontal plate support is fixedly connected to an inner side of the surface layer of the backpack body 1, the backpack body 1 is divided into an upper and a lower independent storage cavities, and the inclined strut 23 is connected between a bottom of the front side of the vertical plate support 21 and a lower end of the front side of the horizontal plate support 22.
In the production process, bearing structure all sets up in the intermediate layer of 1 cloth (surface course) of knapsack body, it is concrete, be equipped with one deck horizontally in knapsack body 1 and cut off cloth (surface course), the diaphragm supports 22 and sets up in this cuts off the cloth, knapsack body 1 divide into about two independent thing chambeies of putting, wherein, the thing chamber space is great on the upper strata, an article used for the device commonly used, it is little that the thing chamber space is put to the lower floor, be used for installing unusual article such as umbrella or little article, be equipped with the zip fastener that is used for opening or closes the thing chamber is put to the upper strata on knapsack body 1 surface course, 1 surface course front portion of knapsack body is equipped with and is used for opening or closes the zip fastener that the thing chamber was put to the lower floor, can also set up the multilayer cyst at the front.
In the use process, the gravity of the backpack is decomposed into two parts of pressure of the backpack straps on the shoulders (namely the bearing force of the shoulders) and the supporting force formed by the supporting structure of the waist and the ilium, and the principle is as follows: the inclined strut 23 and the transverse plate support 22 convert the gravity of the backpack from the original shoulder to the common load of the shoulder and the waist, and G (schoolbag weight) is G1 (shoulder bearing force) + G2 (waist and ilium triangular supporting force).
In a preferred embodiment, the brace 23 comprises two strip-shaped stays, which are respectively disposed in the interlayers of the left and right side panels of the backpack body 1 and have both ends connected to the front lower ends of the horizontal plate supports 22 and the bottom portions of the vertical plate supports 21.
