Hereinafter refer to relevant indicators, to describe measurement process and the method for measuring equipment 1 in detail.
Please respectively refer to shown in Fig. 2 A, Fig. 2 B, Fig. 3 A and Fig. 3 B, wherein, Fig. 2 A is that button B puts
Schematic perspective view on measuring equipment 1, Fig. 2 B is that the measuring equipment 1 of present pre-ferred embodiments is when measuring
Action schematic diagram, the process step of the method for measurement of a kind of button resilience time of Fig. 3 A present pre-ferred embodiments
Figure, and the functional block diagram of a kind of measuring equipment 1 that Fig. 3 B is present pre-ferred embodiments.
As shown in Figure 3A, the method for measurement of the present invention includes step S01～step S05.
First, step S01 is: provide body 11 carry button B, body 11 include the first conductive part C1 and
Second conductive part C2.In this, button B is placed on the test film 113 of body 11, and make conductive particle C with
Pressure survey portion H is correspondingly arranged.Specifically, in order to test button B, measuring equipment B is to utilize H pair, survey portion of pressure
The conductive particle C that can conduct electricity should be pressed down, and utilize its conducting electric current of detecting to obtain the resilience time of button B.
Then, carrying out step S02, step S02 is: control pressure survey portion H close to button B so that conductive particle C
Contact the first conductive part C1 and the second conductive part C2.In this, as shown in Fig. 2 B and Fig. 3 B, when user is pressed
Compress switch the most in advance 15 time, control unit 14 can control drive mechanism 12, makes drive mechanism 12 drive reference test bar 13
Pressure survey portion H move down at leisure and under press button B, when button B is extruded down, conductive particle C can be past
Under touch the first conductive part C1 and the second conductive part C2, make the first conductive part C1 and the second conductive part C2 electricity
Property conducting.
Then, step S03 is: when sensing conducting electric current I1 reaches maximum, produce enabling signal fixed to control
Time device start timing, and control pressure survey portion H away from button B simultaneously.Wherein, extrude at leisure as pressure survey portion H
Button B so that conductive particle C and the first conductive part C1 and the second conductive part C2 contacts and turns on the first conductive part
During C1 and the second conductive part C2, as shown in Figure 3 B, the first conductive part C1 and the second conductive part C2 can pass through
The conducting of conductive particle C and and produce electricity loop between control unit 14, thus produce conducting electric current I1.Wherein,
Due to the shape for example, taper of conductive particle C, thus by pressure survey portion H pressure and contact the first conductive part C1 and
During second conductive part C2, conductive particle C and the first conductive part C1 and the contact surface of the second conductive part C2
Long-pending increasing, therefore conducting electric current I1 is the most increasing.Finally, conductive particle C and the first conductive part C1 and
When second conductive part C2 completely attaches to, conducting electric current I1 can reach maximum, and now control unit 14 produces and opens
Dynamic signal starts timing with control timer 17, and controls pressure survey portion H away from button B simultaneously.It addition, this reality
The control unit 14 executing example has sensing component 141 and processing module 142, and sensing component 141 is electrically connected with and drives
Motivation structure the 12, first conductive part C1, the second conductive part C2 and intervalometer 17, and processing module 142 electrically connects
Connect intervalometer 17.In this, can be by the value of the sensing component 141 sensing conducting electric current I1 of control unit 14.
Wherein, when sensing component 141 sensing conducting electric current I1 begins with downward trend after increasing to a certain numerical value just
Can be described as reaching maximum.It addition, when turning on electric current I1 and reaching maximum, sensing component 141 can be automatic
Mode or manual mode produce enabling signal.Wherein, " automatic " represent the conducting when sensing component 141 detects
When electric current I1 reaches maximum, sensing component 141 automatically generates enabling signal.It addition, " manually " represent, lead
When galvanization I1 reaches maximum, user after being manually pressed by an activate switch, sensing component 141 just produces
Enabling signal.In the present embodiment, as a example by sensing component 141 automatically generates enabling signal, and control timer
17 start timing, and control pressure survey portion H away from button B simultaneously.In this, such as, may utilize elastic force sizable
Elastic component (figure does not shows), makes the quick upward retraction of reference test bar 13, and its speeds comparable button B nature resilience
Speed go up decades of times soon.Therefore, button B will make conductive particle C leave the first conduction because of its elastic-restoring force
Portion C1 and the second conductive part C2.
Then, carrying out step S04 is: when sensing conducting electric current I1 and being zero, produces end signal to control
Intervalometer 17 stops timing.In this, sensing component 141 persistently can turn on electric current I1, when sensing conducting by sensing
(represent conductive particle C the most fully out first conductive part C1 and the second conductive part C2, make two when electric current I1 is zero
Person is insulation), then sensing component 141 produces end signal control timer 17 and stops timing.
Finally, carry out step S05: receive the feedback signal that intervalometer 17 sends after stopping timing, and accordingly
Calculate intervalometer 17 start timing and stop the time interval of timing, to produce the resilience time of button B.In this,
The sensing component 141 of control unit 14 produces after end signal control timer 17 stops timing, intervalometer 17
Feedback signal can be sent, and after the processing module 142 of control unit 14 receives feedback signal, processing module 142
Calculating intervalometer 17 again start timing and stop the time interval of timing, this time spacing (i.e. time difference) is
The resilience time of button B, finally, the processing module 142 of control unit 14 Control Items 16 again shows
The resilience time.
The above is only illustrative, and non-limiting.Any without departing from spirit and scope of the invention, and right
Its equivalent modifications carried out or change, all should be included in claim limited range.
