When user no longer presses button cap 42, the pushing force put on button cap 42 disappears, the magnetisable coating 421 on the magnetive attraction absorption button cap 42 that magnetic element 431 is produced.Therefore, button cap 42 moves toward the direction of magnetic element 431 in response to magnetive attraction, and till the first button cap edge 424 moving to button cap 42 contacts with the frame edge 433 of framework 43, that is button cap 42 gets back to the position of the first height H 1*, as shown in Figure 6.
Specifically the press-key structure 4 of this preferred embodiment is not provided with Connection Element, that is button cap 42 is not fixed on base plate 40.The press-key structure 4 of this preferred embodiment by multiple inclined guide grooves 432 of framework 43 support keys cap 42 in the top of switching circuit board 41, and the structure of the top at multiple first button cap edges 424 of button cap 42 is positioned at by multiple frame edge 431 of framework 43, to stop that button cap 42 is deviate from by framework 43, and button cap 42 can be fixed in framework 43.In the process that button cap 42 is touched, due to multiple declining lugs 423 of multiple inclined guide groove 432 support keys cap 42, when user presses button cap 42, multiple inclined guide groove 432 continues contact with declining lug 423 and one can be provided to press feel, what feel that what user experienced press provided close to elastic caoutchouc presses feel, therefore, when user operates press-key structure of the present invention, can experience and familiar press feel, and can not be like a fish out of water.
In addition, the present invention also provides one the 4th preferred embodiment.Refer to Fig. 9, it is the structure schematic side view of press-key structure of the present invention in the second preferred embodiment.Press-key structure 5 comprises base plate 50, switching circuit board 51, button cap 52 and a framework 53.Button cap 52 comprises multiple magnetic element 521, trigger units 522 and multiple declining lug (not being shown in figure), and framework 53 comprises multiple magnetisable coating 531 and multiple inclined guide groove (not being shown in figure).The structure of the press-key structure 5 of this preferred embodiment is identical haply with the press-key structure 4 of aforementioned 3rd preferred embodiment, and its something in common then no longer adds explanation.Two are had as the press-key structure 5 of this preferred embodiment and press-key structure 4 difference of the 3rd preferred embodiment; 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 trigger unit 522 is with made by soft materials, the impact produced when trigger unit 522 is contacted with switching circuit board 51 portion 522 that is triggered absorbed, and protection switch circuit board 51.
The second, multiple magnetic element 521 is arranged on a upper surface 5241 at the first button cap edge 524 of button cap 52.On the other hand, framework 53 has multiple magnetisable coating 531, its a lower surface 5321 being arranged at multiple frame edge 532 of framework 53 is positioned at the top of corresponding magnetic element 521, and wherein metal material is formed on the lower surface 5321 of multiple frame edge 532 with coating method by magnetisable coating 531.Operation situation as the press-key structure 5 of this preferred embodiment is also identical haply with the press-key structure 4 of aforementioned 3rd preferred embodiment, therefore no longer adds explanation.
According to above-mentioned each preferred embodiment, press-key structure of the present invention is not provided with and holds flimsy elastic caoutchouc, and on the lower surface of button cap, be provided with the trigger unit in order to triggered switch circuit plate.And magnetic element is set on button cap, and the magnetisable coating corresponding to magnetic element is set on framework, or, on framework, magnetic element is set, and the magnetisable coating corresponding to magnetic element is set on button cap, the magnetive attraction produced by magnetic element and carry out button cap touched after homing action, with make button cap be returned to touched before position.Therefore, can not there is the situation that elastic caoutchouc damages in press-key structure of the present invention, and user does not also need the work carrying out replacing elastic caoutchouc.
Moreover, due to the respective outer side edges magnetic element of multiple declining lugs of the multiple inclined guide groove in framework and button cap and the position configuration of magnetisable coating, and can provide provide close to elastic caoutchouc press feel, so that user's operation.On the other hand, in the process that press-key structure of the present invention is touched, button cap moves up and down, or tiltedly goes up the movement tiltedly.And magnetic element and magnetisable coating adopt structure setting up and down mutually, make the close together between magnetic element and magnetisable coating, and its setting direction is identical with the moving direction of button cap or close, therefore, the magnetive attraction that magnetic element produces can provide preferably adsorption effect, so that the movement of button cap.
In addition, because press-key structure of the present invention only the one in button cap or framework need arrange magnetic element, therefore only need arrange one on single element (such as button cap) can the space of accommodating magnetic element, and magnetisable coating is formed with coating method on another element (that is framework), therefore, press-key structure of the present invention can reduce the cost in manufacture.
The foregoing is only preferred embodiment of the present invention, and be not used to limit claim of the present invention, under therefore all other does not depart from disclosed spirit, the equivalence that completes changes or modifies, and all should be contained in the claim of this case.
