A button force measurement curvometer

Abstract

The invention discloses a button force measurement curvometer comprising a frame, a workbench, a protective cover, a test host machine and a button test mechanism. The protective cover is provided with a display screen and control buttons. The test host machine is installed in the frame. The button test mechanism is arranged on the workbench. Data tested by the button test mechanism is processed by the test host machine and then reflected by the display screen. According to the scheme of the invention, a to-be-tested product is placed on a product carry tool; and then the button test mechanism tests the to-be-tested product; comfortableness of traditional buttons is quantified; 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 instrument, 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...

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 weight is tested, and the button with a resistance greater than this weight is judged as bad, but the disadvantage is that the button with too small resistance cannot be detected, and the displacement during the pressing process cannot be detected, so this solution still cannot Fully reflect the user's tactile comfort during the keystroke process
