Pressure sensing device and electronic apparatus having same

Abstract

The displacement sensor and the second panel maintain a certain distance, when the pressing force acts on the first panel, the first panel is bent deformation by the constraint of the supporting wall of the second panel, at this time the displacement sensor is connected to the first panel and follows the deflection deformation. The deflection deformation of the first panel causes the plane in which the displacement sensor is located to cause a change in the length of the dimension after bending, and the displacement sensor measures the change in the length of the dimension to obtain the magnitude of the pressure. The pressure sensing device and the electronic apparatus having the pressure sensing device are easy to process, have good tolerance to the environment, are not easily changed by external impacts, and provide accurate pressure measurement.
