Dummy contact pressure tester with variable circumference

Abstract

The invention relates to a dummy contact pressure tester with variable circumference. The dummy contact pressure tester comprises a dummy model which is a split type cavity model and is composed of four parts of curved surface model plates divided by coronal planes and sagittal planes, wherein a plurality of pressure sensing devices are embedded in the curved surface model plates; a linkage device which is located in the split type cavity model and is used for driving the curved surface model plates to expand and contract along the radial direction; and a control processing system which is used for controlling the linkage device, so that the dummy model can simulate the multi-dimensional change of the circumference of a human body and acquire the pressure data acquired by the plurality of pressure sensing devices. According to the invention, the multi-dimensional change of the human body circumference can be reflected.

Description

technical field [0001] The invention relates to the technical field of clothing precision measuring instruments, in particular to a dummy contact pressure tester with variable girth. Background technique [0002] Clothing pressure is one of the important indicators to evaluate the comfort, functionality and safety of pressure clothing. Pressure clothing has been widely used in the body shaping industry, medical care industry and sports protection industry, and it is imminent to develop professional pressure testing instruments suitable for multiple specifications of clothing. [0003] First of all, in the existing on-body clothing pressure testing device, the pressure-sensitive element is directly inserted between the clothing and the human body, and the pressure of the clothing is sensed and displayed through the corresponding element. There are certain limitations in directly measuring clothing pressure on the human body: ①The body is constantly moving, and it is difficul...

AI Technical Summary

Problems solved by technology

There are certain limitations in measuring clothing pressure directly on the human body: ①The body is constantly moving, and it is difficult to obtain more accurate data

②Testing on human body is time-consuming and expensive

③It is not suitable for the daily evaluation test of the product

Secondly, most of the existing in vitro clothing stress test dummies have an overall structure with a fixed three-dimensional size

Thirdly, on the existing human dummies, the pressure sensing element is a smooth bump-shaped design, which is easy to scratch and hang the clothing during the test, causing local deformation

Therefore, in the previous patent application, a smart dummy clothing pressure testing system with variable body shape was developed to a certain extent (name of invention patent application: a dummy testing system for pressure clothing and its testing method, application number: 201810866308.2), the In the invention patent application, the dummy is divided into the left half dummy and the right half dummy along the front midline and rear midline. The cross-shaped column is fixed on the platform, and the column is connected with a slider to control the left and right half dummy to the left and right. Movement, which is only limited to simulating changes in the width of the human body, cannot reflect multi-dimensional changes in the circumference of the human body
