Device and method for testing sensitivity of spinal curvature detector

Abstract

The invention relates to a spinal curvature detector sensitivity testing device and a testing method. The spinal curvature detector sensitivity testing device structurally comprises a sensor detection sample holder bending mechanism of a back-hung sensor, a touch screen display controller and an electric appliance box body. The device utilizes mechanical power to drive the sample holder to bend, and the controller controls and monitors the angle change of each linkage block, so as to achieve the purposes of simulating the bending of the back of a human body and determining whether the spine bending detector gives an alarm or not when the bending reaches a fixed angle. Through the arrangement of the waist body linkage block and the neck linkage block, the bending states of the neck, the chest and the waist of the back of a human body can be simulated, the structure is reasonable, operation is easy, and result uncertainty caused by a real person test is avoided. According to the invention, the reproducibility of a fixed angle bending state is good, the consistency and accuracy of test data are high, and test errors caused by lack of necessary test devices and manual operation are effectively overcome.

Description

technical field [0001] The invention belongs to instruments and equipment, and relates to a sensitivity testing device for a spinal curvature detector, which is suitable for the development, production and testing of prompting posture correction products based on angle changes of angle sensors. Background technique [0002] Poor sitting posture is an important cause of diseases such as myopia, neck, shoulder and back pain, and spondylosis. The launch of any new type of posture correcting products will bring consumers' pursuit. The spinal curvature detector is a prompt posture correction product based on the angle change of the angle sensor, and it is currently the mainstream product on the market. However, the sensitivity test for the spine curvature detector has the following problems: [0003] The spine bending detector is placed in the posture correction product, and when testing its sensitivity during use, one way is to test the sensitivity of the detector when the ang...
