Furthermore, the present embodiment can also evaluate the actual condition of the key force by analyzing the changes (including slope, mean, etc.) of the curve, so as to better feed back the actual use feeling. The embodiment monitors data of the whole pressing process, records and draws an accurate numerical curve, and provides effective data support for product analysis, definition, design and the like. The hand feeling key pressing process is digitalized and is a better evaluation method for key pressing.

The embodiment is mainly used for pressure detection of the intelligent watch. High-accuracy pressure sensor is fixed motionless, drives intelligent wrist-watch through the electric jar and removes to pressure sensor, after the contact intelligent wrist-watch, feeds specific distance (for example 0.02 mm) at every turn, just reads a pressure sensor numerical value and record, and then draws an X axle and be the displacement (promptly, total motion feed volume), and the Y axle is the curve graph of pressure value. Whether the product meets the design requirements is judged by observing the change rule and the limit deviation of the curve. This embodiment still provides accurate data support for the experience of designing the product, and pneumatic revolving stage effect lies in switching the different button measuring station of product. The present invention eliminates the effect of relative motion on the sensor readings. High detection precision, good repeated consistency, high efficiency and simple operation.
