AI Technical Summary

Technical Problem

Existing technologies cannot efficiently simulate the combined vertical and shear forces exerted by a person sitting up and down during the use of heated seat cushions. Furthermore, manual testing is inefficient and cannot complete bending cycle tests of more than 10,000 times, posing a fire risk.

Method used

A bending test device for heated seat cushions was designed. By applying tension to both ends of the heated seat cushion through a sliding seat and a tensioning element, and using a roller as a bending fulcrum, the device can perform automated repeated bending tests on the heated seat cushion. Combined with the heating element to simulate the actual use temperature, it can perform thousands or even tens of thousands of bending cycles.

Benefits of technology

It improves the efficiency and realism of heated seat cushion bending tests, reliably exposes weak points in internal electrical components, ensures the reliability and consistency of test results, and reduces the risks of manual testing.

Abstract

The utility model provides a bending test device for a heating cushion, which belongs to the technical field of test tools, and comprises a rack, a bending test device, a bending test device and a bending test device, the linear driving element is mounted on the rack, and the linear driving element is connected with the sliding seat; the tensioning element is provided with a second connecting part used for being connected with the other end of the heating cushion. A straight line A which passes through the sliding seat and is tangent to the roller shaft and a straight line B which passes through the tensioning element and is tangent to the roller shaft are not collinear, the sliding seat moves along the straight line A, and the tensioning element moves along the straight line B; the device has the beneficial effects that the device capable of automatically carrying out the bending test on the heating cushion is provided, the sliding seat and the tensioning element can pull the heating cushion to move back and forth relative to the roller shaft, so that the heating cushion is repeatedly extruded by the roller shaft to simulate the bending effect, the effect of automation in the whole process is realized, and the working efficiency is improved. And the test efficiency is improved.
