Detailed Description

The invention is further described below with reference to the accompanying drawings:

examples

A backpack front panel with waterproof and anti-theft functions is shown in figure 1-2 and comprises an inner layer 1, an interlayer 2 and an outer layer 3; the inner layer 1, the interlayer 2 and the outer layer 3 are sequentially molded integrally from top to bottom through a pressing die, the inner layer 1 is made of fabric, the interlayer 2 is made of EVA (ethylene vinyl acetate), and the outer layer 3 is made of fabric or leather; the outer surfaces of the inner layer 1, the interlayer 2 and the outer layer 3 are streamline concavo-convex shapes, the concavo-convex shapes are arc shapes, the bottom in the inner layer 1 is a bearing convex area 7, two sides in the inner layer 1 are concave areas 6, two second convex areas 5 are arranged in the inner layer 1, the second convex areas 5 are positioned between the concave areas 6, and the middle part of the inner top of the inner layer 1 is a first convex area 4; the edge shapes of the inner layer 1, the interlayer 2 and the outer layer 3 are matched with the shape of the waist and back; the first convex area 4 is in a shape of love heart; the shape of the second convex area 5 and the shape of the concave area 6 are both fan-shaped; the load bearing raised area 7 is rectangular and is composed of a plurality of rectangles.

Because the EVA material has the advantages of good buffering, cutting prevention, heat insulation, air permeability, water resistance, fire resistance and the like, and because the inner layer 1, the interlayer 2 and the outer layer 3 are integrally molded through pressing from top to bottom in sequence, the inner layer 1 is made of fabric, the interlayer 2 is made of EVA material, and the outer layer 3 is made of textile fabric or leather, the front piece of the backpack achieves the effects of being not easy to be cut and cracked, preventing fire and having the functions of water resistance and theft prevention;
