Problems solved by technology

Although some progress has been made from the research point of view, and the research indicators are relatively rich, it is a pity that there is still a lack of research on the biomechanical indicators of the shoulder and back pressure when the human body is carrying a heavy load, and there is no biomechanical data support on the shoulders of schoolbags.

Embodiment 1

[0037] The schoolbag pressure regulator provided in this embodiment is designed according to the following methods and steps:

[0038] ①The mFLEX pressure distribution test system was used to collect the static and dynamic pressures of the shoulders and backs of 6-year-old primary school students carrying a school bag with a load of 15% and equipped with a pressure sensor, from standing statically to walking through the test area at a self-selected speed and natural gait value;

[0039] ②Extract the first frame of shoulder and back pressure data in the static state and output it to EXCEL data analysis software for analysis, determine the shoulder and back pressure value, restore the shoulder and back pressure image, and output the restored shoulder and back pressure image in the form of a picture at 1:1. In the static pressure images of the left shoulder, right shoulder and back, respectively mark the position of the force point and the size of the force area, establish the re...

Embodiment 2

[0046] The design method and steps of the school bag pressure regulator that this embodiment provides are different from embodiment 1 in that: this embodiment is a 9-year-old primary school student who collects a school bag with a load of 15% on his back and a pressure sensor, from static standing to self-selection The speed, natural gait walk through the test area, the dynamic and static pressure values ​​of various parts of the shoulder and back, and the rest are the same as in Example 1, so they are omitted.

[0047] The present embodiment school bag pressure regulator obtained by above design method is also as Figure 3-6 As shown, the pressure regulator consists of a pressure regulator 1 for the shoulder and a pressure regulator 2 for the back.

[0048] Wherein there are two pressure regulators 1 for the shoulders, each of which is a rectangular patch with a pressure regulator 1, the patch is 7cm long and 5cm wide, and the rectangular patch of the present embodiment is su...

Embodiment 3

[0052] The design method and steps of the school bag pressure regulator that this embodiment provides are different from embodiment 1 in that: this embodiment is a 12-year-old primary school student who collects a school bag with a load of 15% on his back and a pressure sensor, from static standing to self-selection The speed, natural gait walk through the test area, the dynamic and static pressure values ​​of various parts of the shoulder and back, and the rest are the same as in Example 1, so they are omitted.

[0053] The present embodiment school bag pressure regulator obtained by above design method is also as Figure 3-6 As shown, the pressure regulator consists of a pressure regulator 1 for the shoulder and a pressure regulator 2 for the back.

[0054] Wherein there are two pressure regulators 1 for the shoulders, each of which is a rectangular patch with a pressure regulator 1, the patch is 8 cm long and 6 cm wide, and the rectangular patch of the present embodiment is...

Abstract

The invention provides a design method of a shoulder-back pressure regulator for a pupil schoolbag. The method comprises the steps that data collection is conducted on dynamic and static shoulder-back pressures produced when the pupil schoolbag bears a load of 15% by means of an mFLEX pressure distribution testing system, and images of the dynamic and static shoulder-back pressures are extracted respectively; the area, salient point positions and salient point sizes of pressure regulators for a soft-pad schoolbag are drawn, wherein the designed pressure regulators are formed by two pressure regulators for the shoulders and one pressure regulator for the back, at least four pressure regulation salient points are distributed on one face of each pressure regulator for the shoulders, and at least eight pressure regulation salient points are distributed on one face of the pressure regulator for the back. The shoulder-back pressure regulator not only can relieve the pain, caused by the heavy load and unreasonable structural design of the pupil schoolbag, of the spine, the shoulders, the back and the like, but also can avoid the influence on growth and development of the pupils to some extent; the design pressure regulator is simple in structure, easy to machine and manufacture and convenient to apply and popularize.

Description

technical field [0001] The invention belongs to the technical field of a schoolbag pressure regulator for primary school students and a design method thereof, and in particular relates to a shoulder and back pressure regulator for school bags for primary school students and a design method thereof. The shoulder and back pressure regulators of schoolbags for primary school students conform to the carrying habits and growth and development characteristics of primary school students. Background technique [0002] As we all know, the heavy load and unreasonable structural design of schoolbags will cause pain in the spine, shoulders and back, which will directly or indirectly affect the growth and development of students. This problem has already attracted widespread attention from the society. How to make schoolbags in use The ability to adjust the pressure on the shoulders and back, and design and manufacture a physical schoolbag that can reduce pressure has become a new hot sp...
