Part 431 is in order to produce a magnetive attraction.Multiple inclined guide grooves 432 are arranged at multiple sidewalls 434 of framework 43
Upper and each inclined guide groove 432 corresponds to a declining lug 423, makes declining lug 423 be inserted into and inclines
In inclined guide groove 432 and contact with inclined guide groove 432, thus, framework 43 supported button cap 42 in
The top of switching circuit board 41.In this preferred embodiment, magnetics 431 is Magnet.
Bolster 44 is arranged on a upper surface 415 of switching circuit board 41 and is positioned at trigger unit 422
Lower section, absorbs an impact force produced by trigger unit 422 in order to contact with trigger unit 422, with protection
Switching circuit board 41.In this preferred embodiment, bolster 44 is with made by soft materials.
Next the operation situation of press-key structure 4 of the present invention is described.Please refer to Fig. 6～Fig. 8, Fig. 8
For the structure schematic side view that press-key structure of the present invention is touched in the second preferred embodiment.Fig. 6 and
Fig. 7 demonstrates the state that button cap 42 is the most touched, and the declining lug 423 of button cap 42 with tilt
One first end 4321 of guide groove 432 contacts, and makes button cap 42 be positioned at one first height H1*, wherein magnetic
Property element 431 adsorbs magnetisable coating 421.When user presses button cap 42, put on button cap
A pushing force on 42 is more than magnetive attraction, makes the first button cap edge 424 of button cap 42 depart from framework
The frame edge 433 of 43, and it is positioned at the declining lug 423 on the second button cap edge 425 in corresponding
Inclined guide groove 432 in slide.The trigger unit 422 being positioned on button cap 42 move toward lower section and with slow
Stamping 44 contacts, and trigger unit 422 triggers switching circuit board 41 and produces push button signalling simultaneously.The opposing party
Face, impact force produced by trigger unit 422 is buffered part 44 and is absorbed, to avoid switching circuit board 41
Impaired because of collision.Now, button cap 42 is positioned at one second height H2*, as shown in Figure 8.Wherein
Second height H2* is less than the first height H1*.And declining lug 423 and the one second of inclined guide groove 432
End 4322 contact.
When user no longer presses button cap 42, put on the pushing force on button cap 42 and disappear, make
Magnetisable coating 421 on magnetive attraction absorption button cap 42 produced by magnetics 431.Therefore, button
Cap 42 direction toward magnetics 431 moves in response to magnetive attraction, and mobile to the first of button cap 42
Till button cap edge 424 contacts with the frame edge 433 of framework 43, that is button cap 42 returns to
The position of one height H1*, as shown in Figure 6.
Specifically, the press-key structure 4 of this preferred embodiment be not provided with connecting element, also
I.e. button cap 42 is not secured on base plate 40.The press-key structure 4 of this preferred embodiment is by framework 43
Multiple inclined guide grooves 432 and support button cap 42 in the top of switching circuit board 41, and pass through framework
Multiple frame edge 431 of 43 are positioned at the top at multiple first button cap edges 424 of button cap 42
Structure, to stop that button cap 42 is deviate from by framework 43, and can fix button cap 42 in framework 43.
During button cap 42 is touched, owing to multiple inclined guide grooves 432 support the multiple of button cap 42
Declining lug 423, when user presses button cap 42, multiple inclined guide grooves 432 continue convex with inclination
Block 423 contacts and one can be provided to press feel, and what user was experienced presses feel close to elastic rubber
What glue was provided presses feel, therefore, when user operates press-key structure of the present invention, can experience
That is familiar with presses feel, without being like a fish out of water.
Additionally, the present invention also provides for one the 4th preferred embodiment.Referring to Fig. 9, it is button of the present invention
Structure structure schematic side view in the second preferred embodiment.Press-key structure 5 includes a base plate 50,
Switching circuit board 51, one button cap 52 and a framework 53.Button cap 52 includes multiple magnetics
521, a trigger unit 522 and multiple declining lug (not shown in the figures), and framework 53 includes multiple
Magnetisable coating 531 and multiple inclined guide groove (not shown in the figures).The press-key structure of this preferred embodiment
The structure of 5 is substantially the same with the press-key structure 4 of aforementioned 3rd preferred embodiment, and its something in common is the most not
Add explanation again.Press-key structure 5 and the press-key structure of the 3rd preferred embodiment as this preferred embodiment
4 differences have two, and first, press-key structure 5 is not provided with the bolster made by soft materials,
In this preferred embodiment, trigger unit 522 is arranged on a lower surface 526 of button cap 52, and touches
Send out portion 522 with made by soft materials, make trigger unit 522 be produced when contacting with switching circuit board 51
The impact force portion 522 that is triggered absorbed, and protect switching circuit board 51.
Second, multiple magneticss 521 are arranged at the one of the first button cap edge 524 of button cap 52
On upper surface 5241.On the other hand, framework 53 has multiple magnetisable coating 531, and it is arranged at framework
On a lower surface 5321 of multiple frame edge 532 of 53 and be positioned at corresponding magnetics 521
Top, wherein metal material is formed at multiple frame edge 532 with coating method by magnetisable coating 531
On lower surface 5321.As for the operation situation of press-key structure 5 of this preferred embodiment also with the aforementioned 3rd
The press-key structure 4 of preferred embodiment is substantially the same, therefore no longer adds explanation.
According to above-mentioned each preferred embodiment, press-key structure of the present invention is also not provided with the bullet being easily damaged
Property rubber, and on the lower surface of button cap, it is provided with to trigger the trigger unit of switching circuit board.And in
Magnetics is set on button cap, and the magnetisable coating corresponding to magnetics is set on framework, or,
Magnetics is set on framework, and the magnetisable coating corresponding to magnetics is set on button cap, logical
Cross magnetive attraction produced by magnetics and carry out button cap touched after homing action so that button
Cap be returned to touched before position.Therefore, press-key structure of the present invention will not occur gum elastic to damage
Situation, and user is also not required to be replaced the work of gum elastic.
Furthermore, owing to the structure of the multiple inclined guide grooves in framework and multiple declining lugs of button cap is joined
Close the position configuration of magnetics and magnetisable coating, and can provide close to touching that gum elastic is provided
Pressure feel, in order to user operates.On the other hand, during press-key structure of the present invention is touched,
Button cap moves up and down, or tiltedly upper tiltedly under movement.And magnetics and magnetisable coating use
Structure the most setting up and down so that close together between magnetics and magnetisable coating, and it sets
Putting direction identical or close with the moving direction of button cap, therefore, produced by magnetics, magnetive attraction can
There is provided preferably adsorption effect, in order to the movement of button cap.
Further, since press-key structure of the present invention only need to arrange magnetic unit in the one in button cap or framework
Part, therefore a space that can house magnetics only need to be set on single element (such as button cap), and in
