[0002] A backpack refers to a bag carried on the back. The materials are diverse, including leather, plastic, polyester, canvas, nylon, cotton and linen. The stress points of current backpacks are often concentrated on the straps, which will cause shoulder and neck fatigue when the user uses the backpack for a long time. At the same time, the straps are easily damaged during long-term shaking use. In particular, most students' backpacks now store a lot of textbooks, which makes the backpacks heavy. Students also have relatively difficulty using the backpacks, and it is also easy to cause hunchbacks. Therefore, it is necessary to develop a backpack back load reduction system to solve the problem that the existing backpacks are only stressed through the straps during use, which is not conducive to reducing the back load of the user.

There are two back load-reducing structures 4, and they are arranged on the back pad 3 in an axisymmetric structure. The backpack 2 straps, the backpack waist belt and the back load-reducing structure 4 constitute the backpack back load-reducing system. The back load-reducing structure 4 includes a bottom pad 41, a load-reducing structure 42, and a hollow 43. The load-reducing structure 42 is arranged on the top of the bottom pad 41. The load-reducing structure 42 and the bottom pad 41 are an integrated structure. The load-reducing structure 42 and the bottom pad 41 are both provided with hollows 43 at the center.

[0023] The shoulder straps of the backpack 2, the waist belt of the backpack 2 and the back load-reducing structure 4 constitute the back load-reducing system of the backpack. The cooperation of the shoulder straps of the backpack 2 and the back load-reducing structure 4 can form a two-way force point on the back during the carrying process of the backpack, effectively reducing the weight on the shoulders of the back during the carrying process. The two symmetrically arranged back load-reducing structures 4 on the shoulders are moved down and adjusted to the waist position of the back pad 3, and also have corresponding load-reducing and ventilation functions. The two symmetrically arranged back load-reducing structures 4 can be arranged on the back pad 3 from top to bottom in sequence. The back load-reducing structures 4 arranged at different positions of the back pad 3 can produce corresponding load-reducing and ventilation effects, effectively improving the comfort and breathability of the backpack.

[0024] Example 2

[0025] A back-load-reducing system for a backpack, such as Figure 2-4 As shown, the back load-reducing structure 4 includes a base pad 41, a load-reducing structure 42, and a hollow 43. The load-reducing structure 42 is arranged on the top of the base pad 41. The load-reducing structure 42 and the base pad 41 are an integrated structure. The load-reducing structure 42 and the base pad 41 are both provided with a hollow 43 at the center. The hollow 43 sequentially penetrates the load-reducing structure 42 and the base pad 41, and is an integrated structure with the load-reducing structure 42 and the base pad 41. The base pad 41 is an elliptical geometric structure with a length of 116MM and a width of 81MM. The load-reducing structure 42 is an elliptical geometric structure, and the load-reducing structure 42 and The thickness formed by the combination of the base pad 41 is 15MM. The load-reducing structure 42 is an elliptical geometric structure formed by the mesh structure interweaving with each other. The formed structure has the functions of ventilation and cushioning. The overall structure of the back load-reducing structure 4 is made by sampling 3D printing technology. The materials used for the base pad 41, the load-reducing structure 42, and the hollow 43 are highly elastic materials. The back load-reducing structure 4 is sewn on the back pad 3. There are two back load-reducing structures 4, and they are arranged in an axisymmetric structure. The two back load-reducing structures 4 arranged in an axisymmetric structure are just adapted to the human shoulder blades.

[0026] There are two back load-reducing structures 4, which are arranged in an axisymmetric structure. The two back load-reducing structures 4 in an axisymmetric structure are just adapted to the human shoulder blades, so that the back load-reducing structures 4 can be embedded in the human shoulder blades and around the shoulders and neck. During the backpack carrying process, the structural characteristics of the back load-reducing structures 4 and the combination of highly elastic materials can improve the comfort of backpack carrying and reduce the load-bearing burden on the back. At the same time, a certain gap can be formed between the backpack and the back, which is conducive to the ventilation of the back and prevents sweating.

[0027] Working principle:

[0028] During the carrying process of the backpack 2, the shoulder straps of the backpack 2 cooperate with the back load-reducing structure 4, the force points of the shoulder straps are set on the shoulders, and the force points of the back load-reducing structure 4 are set around the shoulder blades of the human body, which can effectively distribute the gravity of the backpack during the carrying process, so that the backpack forms a two-way force point on the back during the carrying process, effectively reducing the weight of the back shoulders during the carrying process, and improving the comfort of carrying the backpack. The back load-reducing structure 4 is provided with two, and is arranged in an axially symmetrical structure. The two back load-reducing structures 4 arranged in an axially symmetrical structure are just adapted to the shoulder blades of the human body, so that the hollow 43 in the center of the back load-reducing structure 4 can be embedded in the shoulder blades of the human body, and the elliptical shape formed by the load-reducing structure 42 is used. The circular geometric breathable structure surrounds the shoulder blades. During the backpack carrying process, the structural characteristics of the back load-reducing structure 4 and the combination of high-elastic materials can improve the comfort of carrying the backpack and reduce the weight on the back. The back load-reducing structure 4 can form a certain gap between the backpack and the back, which is beneficial to the ventilation and load reduction of the back. The two symmetrically arranged back load-reducing structures 4 on the shoulders are moved down to the waist position of the back pad 3 and also have corresponding load-reducing and breathable functions. The two symmetrically arranged back load-reducing structures 4 can be arranged on the back pad 3 from top to bottom in sequence. The back load-reducing structures 4 arranged at different positions of the back pad 3 can produce corresponding load-reducing and breathable effects, effectively improving the comfort and breathability of the backpack.
