Specific embodiment
Button fatigue hand evaluation method of the present invention, it comprises the following steps：
(1) button to be detected is repeatedly pressed, often by carrying out pressing force value test after pre-determined number, by pulling force
Test machine is pressed button to be detected, and button is touched from measurer for pulling force, arrives range to pressing, then be repositioned to button
Initial position is used as once complete button process；
(2) when the displacement of handfeel of keys value and trigger point reaches predetermined value, the touch potential for being detected is button reality
Service life, wherein now keys deactivation, Handle Value are that maximum pressing force subtracts the ratio with maximum pressing force after trigger force, are used
Percentage is expressed as：
Wherein F1 is initial maximum pressing force, and F2 is trigger point force value, works as hand
It is keys deactivation when inductance value is less than 30%, the displacement of trigger point is the pressing force value displacement at trigger point, when the position of trigger point
When shifting reaches predetermined value, the number of times for being detected is button actual life, now keys deactivation.
Naturally it is the change of pressure to the pressing of button.Handle Value is carried out " test of power " primarily directed to pressing keys.
For certain key press test of single keyboard.The present invention summarizes the force value of the key press stroke of multiple various keyboards
Determine, it is proposed that brand-new measurement definition and detection method.Measurer for pulling force touches button from the beginning, and maximum row is arrived to pressing
Journey, then be repositioned to initial position as a complete circulation and gather the data of each node.
With reference to shown in Fig. 1, by the force value and the graph of a relation of stroke of button 1, we can be found that the first peak F1 on figure
Point is the Incipient maximum force of pressing, and F2 points in valley point produce the node of electric signal after being depressed for the conductive rubber of button 1, also referred to as
Trigger point.Daily when using, the change of the power before the feel of button depends primarily on trigger point.
For the embodiment of the change in force value of feel, present inventor has performed the life test of a set of keyboard, by right
Pressing force value displacement curve after each step-by-step test determines the relation of feel change and force value.
Embodiment
Be below the life test to certain keyboard, the mainly button to keyboard is tested, carry out altogether 1,000,000 times by
Pressure, and it is initial i.e. after carry out force value tests and list wherein 3 Data Comparisons of button for every 500,000 times：Wherein L2 is triggering
Point displacement.
| No. 1 button | Initial value | After 500000 times | After 1000000 times |
| F1, N | 1.221 | 1.129 | 1.135 |
| F2, N | 0.753 | 0.706 | 0.733 |
| L2, mm | 1.324 | 1.254 | 1.237 |
| No. 3 buttons | Initial value | After 500000 times | After 1000000 times |
| F1, N | 1.331 | 1.145 | 1.059 |
| F2, N | 0.831 | 0.733 | 0.71 |
| L2, mm | 1.324 | 1.237 | 1.22 |
One good pressing feel should push button rear smooth, there is a change of obvious force value, and if button
There is viscous sense after conductive rubber is aging or button is repeatedly pressed, the F1 in above-mentioned experiment is Incipient maximum force, F2 is conduction
Rubber trigger point force value, L2 is trigger point displacement.Number of times with experiment increases, and button also begins to gradually aging, and feel is also got over
Come poorer, since annex curve map it can also be seen that being tapered into the difference of F2 and F1, this also means that the change of force value becomes
Small, it is more and more stiff that pressing feel starts, and L2 is the displacement of trigger point, and shift value diminishes, and illustrates that button is produced viscous, returns
Bullet has been not so good as original state.
So far, the present invention draws the definition of " Handle Value "：Handle Value be maximum pressing force subtract after trigger force with maximum by
The ratio of pressure, is expressed as a percentage, and formula is as follows：
" displacement " this detected value is proposed simultaneously, is contrasted with the testing result of Handle Value, mutually echoed.
The calculated value of experimental data is：
| No. 1 button | Initial value | After 500000 times | After 1000000 times |
| C, % | 38.33 | 37.46 | 35.42 |
| L2, mm | 1.324 | 1.254 | 1.237 |
| No. 2 buttons | Initial value | After 500000 times | After 1000000 times |
| C, % | 50.61 | 48.08 | 44.48 |
| L2, mm | 1.488 | 1.365 | 1.309 |
| No. 3 buttons | Initial value | After 500000 times | After 1000000 times |
| C, % | 37.66 | 35.98 | 32.96 |
| L2, mm | 1.324 | 1.237 | 1.22 |
With reference to shown in Fig. 2-Figure 10, when No. 1 button, No. 2 buttons, No. 3 buttons are in initial press, 500,000 pressings and
Button force value and trigger point displacement relation figure during 1000000 pressings, it can be seen that Handle Value C is with the increase of experiment number
Constantly diminishing, and L2 triggering shift values are also diminishing.Illustrate that button becomes feel worse and worse with experiment number, also open
Beginning has viscous effect resilience not abundant enough.Data meet actual conditions.(detection data and actual effect are consistent)
In order to further determine that the failure conditions of button and the relation of Handle Value, the present inventor determines further research, presses
Handle Value when key is completely viscous when (failure) can not be used normally with lower keyboard determining Handle Value.The method of use
It is to use above-mentioned testing fatigue, does the Handle Value that feature is checked and calculates respective stage every 500,000 times, until keyboard failure.
Found after experiment, have continuous signal input after the button of keyboard viscous, that is, is pushed button, button is pressed
There is obvious clamping stagnation sense.Now sample button is defined to have failed.
Calculated by the Handle Value fixed above, Handle Value now is assert for 29.71% event is preliminary：Handle Value 30% with
It is down keys deactivation.
Present invention firstly provides " Handle Value " as detection limit and life-span fatigue index quantized value, and provide definition and measure
Method, pressing test is carried out with measurer for pulling force to the button after each number of times fatigue experiment, determines the relation of force value and displacement
And Handle Value and the two concepts of trigger point displacement are introduced, the feel for intuitively evaluating button changes and service life.It is logical
Cross this class abstract concept to feel to study, embody it, to show and enable production unit or enterprise in data
The enough service life or feel that must compare button directly perceived.Lateral comparison can carry out the contrast of feel to different products, indulge
Carry out testing fatigue and can determine that the feel of same product, with the increased change of access times, draws service life to comparing,
Make the real data for feeling to be changed into may compare, can examining that itself is abstract.Propose a kind of to key board using effect and making
The detection method with examination is checked with the life-span.It is easy to a kind of assessment side that the capability and performance of like product is detected and evaluated
Method.
