Design of display retractile testing mechanism based on crank rocker

This article designs a testing mechanism to simulate the retractile process for foldable display. According to the requirement of stable working and smallest dimensions, we choose the crank rocker as the basic mechanical principle for the testing device, and we remove its quick-return characteristics; then we analyze the whole motion process of the testing mechanism, and build the mathematical model; at last we build the 3D modeling and make the simulated analysis. Based on the results, we get the way the related parameters effect the diver torque. This theory analysis and modeling method can be used as the basis of the same kind of testing mechanism.
