[0031] In detail, the middle part of the support plate 17 is arched away from the school bag body 1, and the structural characteristics of the support plate 17 are utilized to make the support plate 17 fit the spine curve of the child better and conform to ergonomics. In this embodiment, the material of the support plate 17 is a deformable metal, and in other embodiments, it can also be carbon fiber;

[0032] Preferably, the middle portion of the back breathable sponge 18 is a hollow structure, and by utilizing the structural characteristics of the back breathable sponge 18, the heat stored in the back can be promptly discharged while improving the fit between the skin-friendly fabric 16 and the back.

[0033] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0034] Working principle: First, the child puts on the shoulder strap 2. With the setting of the decompression airbag, it can effectively reduce the pressure on the child's shoulders. Then, the restraint strap 4 is passed around the front of the child's body, and the positioning male buckle 5 is inserted into the positioning female buckle 6. Then the waist support strap 3 can be wound around the child's waist. Subsequently, the air pump 10 is started, and gas is injected into the airbag belt 7 through the air delivery pipe 12, causing the airbag belt 7 to expand and fit the child's waist. During the child's movement, the pressure of the schoolbag main body 1 can be conducted to the lower limb part of the child through the airbag belt 7, so that the pressure is transferred to the lower limbs, thereby sharing the pressure on the child's shoulders and upper body and protecting the spine;

[0035] And with the setting of the support plate 17, it can fit the child's spine, provide auxiliary support for the child's spine, and reduce the pressure on the child's spine;

[0036] At the same time, after the airbag belt 7 is inflated with one key, it moves up and down. The bottoms of the two support plates 17 will contact the airbag belt 7 and hold the support plate 17, so that the support plate 17 conforms to the physiological curvature of the lumbar spine to support the schoolbag main body 1;

[0037] After repeated experimental comparisons, under the condition of the same book weight, the overall pressure on the child's shoulders after inflation of the present utility model can be reduced by 42% compared with that before inflation, and the overall pressure on the child's waist can be reduced by 27%. After inflation of the present utility model, compared with a traditional schoolbag without a waist decompression component and a back decompression component, the overall pressure on the child's shoulders can be reduced by 56.7%, and the overall pressure on the child's waist can be reduced by 36.5%. Protecting the spine and reducing pressure makes it more convenient for children to use.
