A button force measurement curvometer

Abstract

The invention discloses a button force measurement curvometer characterized in that the button force measurement curvometer comprises a frame, a data acquisition system cabinet, an electrical control cabinet and a button test mechanism; the data acquisition system cabinet is installed above the frame; the electrical control cabinet is installed below the frame; the button test mechanism is arranged between the data acquisition system cabinet and the electrical control cabinet; the electrical control cabinet controls running of the button test mechanism; and data tested by the button test mechanism is displayed and reflected by the data acquisition system cabinet. According to the scheme of the invention, through the data acquisition system cabinet, the electrical control cabinet and the button test mechanism, comfortableness of traditional buttons is quantified; and the whole process of button triggering is effectively reflected in the mode of curve coordinates in terms of a push stroke and counterforce. Indexes such as a maximum counterforce, a minimum counterforce and press down displacements are tested so as to provide more convenience for quality management and control in a production process.

Description

technical field [0001] The invention relates to a key force measuring curve machine, which belongs to key detection in the fields of computers, automotive electronics and consumer electronics. Background technique [0002] As an important part of the computer, the computer keyboard key must first ensure the effectiveness and accuracy of the user's input operation on the key, and at the same time ensure the comfort of the user's keystrokes (from the rebound resistance of the key during the keystroke process). Decide). According to the development and evolution of keyboard key detection in the industry, it can be roughly divided into two generations at present. The first generation of key detection is manual detection. qualified. The second generation of key detection is weight detection, through which the weight of the standard weight is automatically pressed down, and the key that can be triggered is a qualified key, and the key that cannot be triggered due to excessive re...

AI Technical Summary

Problems solved by technology

Both of the above-mentioned methods have deficiencies: the first generation of manual detection is slow, and the comfort of the keys cannot be quantified by the operator's hand feeling, which is likely to cause misjudgments or missed judgments of defective products; the second generation of weight detection can only The pressure of a single we
