Description
Technical field
The present invention relates to a kind of physical button to tap test system.
Background technology
Physical button is most common input equipment, at present, from personal PC external keyboards to notebook built-in keybad and
Non-inductive formula button on electronic product is all physical button, and physical keyboard is by keycap, triggering contact chip, rebound spring group
Into.Physical button is to need user to use human hand contact-key cap, and pushes keycap untill button triggers, after the completion of button
Human hand leaves button, and keycap is upspring reset.In this action process button key spring, key stroke, button trigger sensitivity,
Whether occur repeated code these aspects be all directly related to user experience it is good with it is bad.Button key spring be according to ergonomics into
Row design, button key spring is one of most important detection, and button key spring influences whether the feel that button uses.It is higher at present
The test equipment percussion power power output error at end is 40gf, but more preferable user experience in order to obtain, test equipment percussion power are defeated
The error of output is constantly reducing.
The key-press test method of present generally use on the market has following several below：
1. human hand key detecting method.This detection mode is pushed button by human hand, if button is triggered, test equipment
Prompting just occurs above display, if just explanation button is not triggered without prompting.This method is merely able to detection button
It is no to be triggered, the elastic force of button can not be detected, and low production efficiency, it may appear that the mistake above human factor
By mistake.This detection method is used primarily in above low side keyboard and low-end product with button.
2. using electromagnet as the key detecting method of driving force.This detection mode is that solenoid actuated striking head carries out
Directly tap, this method can carry out tapping detection automatically, but the difference due to electromagnet coiling and the influence of resetting spring, defeated
Go out that the fluctuation range of percussion power is very big, and the size that can not change power output at any time according to customer requirement changes power output
Size must replace electromagnet, and with the continuous aging of spring, output percussion power can also change, in uncontrollable state.
This detection method is used primarily in above low and middle-end keyboard and mid and low-end products with button.
3. add the key detecting method of spring with weight linear meter.This detection method uses weight linear meter, with the side of free-falling
Formula whereabouts key tap, and buffered using spring.This mode has equipped with fixed weight linear meter, and uses the shape of freely falling body
Formula carries out impact percussion, is well controlled to tapping power output, can be by power output control errors in 40gf.It is but this
Method needs to rely on spring buffer, and spring itself is variant, and can not change the big of power output at any time according to customer requirement
The small size for changing power output must replace weight linear meter and spring, and with the aging of spring, tapping power output can also change.
The most important problem of several detection methods above is not controlling tapping the accurate of power output, and cannot
Enough to change the size for tapping power output at any time according to customer requirement, also there are many uncontrollable factors.
The content of the invention
