Irregular curved surface pressure testing structure adapting to various states of human body

Abstract

The invention discloses an irregular curved surface pressure testing structure adapting to various states of a human body. The structure comprises a sensor sheet for fitting with the surface of the human body, wherein an information processing ring is arranged at an end, away from the human body, of the sensor sheet, and the information processing ring and the sensor sheet are connected; a force transfer ball is arranged in an inner circle of the information processing ring, is connected with the inner circle of the information processing ring, and is always kept in a horizontal state; a contact sensor is arranged outside the information processing ring, and the force transfer ball is in contact with a contact of the contact sensor. The irregular curved surface pressure testing structure adapting to various states of the human body has a simple structure, can automatically adapt to the change of a curved surface of the human body, and can freely swing according to a contact surface, soas to ensure that the contact surface can fit with the surface of the human body in different states in real time; the force interference of a flexible connection is eliminated through a calibrationtechnology, thereby ensuring the test accuracy while performing safety protection on the surface of the human body during testing.

Description

technical field [0001] The invention relates to a pressure test structure, in particular to an irregular surface pressure test structure adaptive to various states of a human body. Background technique [0002] With the development of mankind today, science and technology have made great breakthroughs in all walks of life, and have made great contributions to the benefit of mankind; however, there are still many blind spots in human understanding of the human body, such as basic research on the mechanics of the human body. Still in the initial stage of understanding. [0003] A more accurate understanding of human body mechanics will help in the research of diseases such as human bone deformation, cerebral palsy, hemiplegia, and paralysis; at the same time, it can provide more perfect theoretical data for industrial products such as intelligent correction brackets, intelligent wheelchairs, and human recovery. . [0004] At present, the sensors used in the study of human bo...

Problems solved by technology

[0008] The technical problem to be solved by the present invention is that the existing structure for pressure testing on the surface of the human body is inaccurate, and it is easy to cause injuries to the surface of the human body. , the test structure can automatically adapt to changes in the surface of the human body, accurately test the pressure on the surface of the human body, and at the same time protect the surface of the human body during the test

In the human body pressure test, the test device is attached to the surface of the human body. At present, the thin film pressure sensor is more commonly used, which is attached to the surface of the human body and then feels the pressure to transmit the pressure signal. Wireless Bluetooth is even used. Passed to the operator, this kind of sensor is soft in texture. In order to fit it to the surface of the human body, the area is relatively large, which will cause discomfort to the human body. Moreover, due to the bending or movement of the human body, there will be a large area of ​​suspension. The surface of the human body is completely fitted, and there is a vacuum area during the test, so accurate testing cannot be performed
