Description
Technical field
The utility model is relevant for a kind of many hardness combined type rubber blanket and have its button, refers to especially a kind ofly be used as power strong and push long rubber blanket of life-span and have its button.
Background technology
See also the button of a kind of convention keyboard shown in Figure 1; This convention button 10 is provided with elastomer 13 between keycap 11 and substrate 12; Elastomer 13 has main body 131, is provided with start post 132 in main body 131 bottom surfaces, and start post 132 corresponding is arranged at the hollow part 121 of substrate 12; Be provided with scissor syndeton 14 between keycap 11 and the substrate 12; This scissor syndeton 14 is interlocked by two and first support 141 and second support 142 of pivot joint each other constitute, and the top of first support 141 and second support 142 is articulated in keycap 11 bottom surfaces, and the bottom of first support 141 and second support 142 is articulated in substrate 12; Keycap 11 supports by main body 131 and keeps a height; When pressing down keycap 11, can oppress main body 131 distortion and start post 132 is sunk through hollow part 121, start post 132 can contact with the switch (not shown) that is arranged at substrate 12 bottoms and touch switch electrically conducts; And when the pressure that acts on keycap 11 disappeared, keycap 11 can automatically return to original height by the elastic force effect of main body 131.
The manufacturing approach of at present general elastomer 13 is to adopt the rubber material one-body molded, and main body 131 is identical rubber material with start post 132; Yet because main body 131 must be able to bear repeatedly by compressive strain, and start post 132 must have suitable hardness and can reach and push smoothly and touch switch; Result in when selecting rubber hardness and have problems, for example, the hardness of main body 131 is lower than 40 when spending; Can have best pushing the life-span, and the hardness of start post 132 is higher than 60 when spending, and can obtain best start effect; But in order to take into account the two, the dealer often must select the median hardness between the two, for example the hardness between 40 to 60 degree; Cause be used as power difference and to push the life-span short of elastomer 13 so on the contrary, also influence the useful life of convention button 10 simultaneously.

For achieving the above object, the utility model more proposes a kind of button, comprises many hardness combined type rubber blanket, keycap, substrate and connecting structure.Many hardness combined type rubber blanket comprises body and cylinder; This body has the press section; This press section has relative end face and bottom surface; This bottom surface in this press section is provided with the ring-side wall with first hardness, and this ring-side wall encloses the formation accommodation space, and this cylinder that has greater than second hardness of this first hardness is arranged in this accommodation space of this body.Keycap is arranged at this end face of this press section of this many hardness combined type rubber blanket.Substrate is arranged at this sidewall with respect to the one side that is provided with this press section.Connecting structure is arranged between this keycap and this substrate, and this connecting structure connects this keycap and this substrate.
According to the described button of the utility model, the press section is in order to bear a pressure, and the direction of this pressure is parallel to first direction, and this cylinder has a length, and the length bearing of trend of this cylinder is parallel to this first direction.
According to the described button of the utility model, first direction is perpendicular to substrate.
According to the described button of the utility model, the setting that is formed in one of body and cylinder.
According to the described button of the utility model, connecting structure is a scissors pin connecting structure.
Through many hardness combined type rubber blanket that the utility model provides, button is had be used as power strong, push long advantage of life-span, and can prolong the useful life of button.

Embodiment
For making purpose, structure, characteristic and function thereof that further understanding arranged, cooperate embodiment to specify as follows now to the utility model.
See also shown in Figure 2, many hardness combined type rubber blanket 20 that the utility model provided, it comprises body 21 and cylinder 22; Body 21 is formed in one with cylinder 22, and body 21 has press section 211, and press section 211 has relative end face 2111 and bottom surface 2112; 211 bottom surface 2112 is provided with ring-side wall 212 in the press section, and this ring-side wall 212 encloses and forms accommodation space 213, and the material of this ring-side wall 212 adopts the rubber material with first hardness; The end face 2111 of press section 211 is in order to bear a pressure, and the direction of this pressure is parallel to first direction F1, in addition; Cylinder 22 is arranged in the accommodation space 213 of body 21, and cylinder 22 has a length, and the length bearing of trend of cylinder 22 is parallel to first direction F1; The material of cylinder 22 adopts the rubber material with second hardness, first hardness that second hardness that cylinder 22 is had is had greater than body 21, for example; First hardness of body 21 is equal to or less than 40 degree, and second hardness of cylinder 22 is equal to or greater than 60 degree, and the big more representative hardness of the number of degrees is high more; That is body 21 is softer and cylinder 22 is harder.
See also shown in Figure 3; This button 100 comprises many hardness combined type rubber blanket 20, keycap 30, substrate 40 and connecting structure 50; Many hardness combined type rubber blanket 20 comprises body 21 and cylinder 22, and keycap 30 is arranged at the end face 2111 of the press section 21 of many hardness combined type rubber blanket 20, and substrate 40 is arranged at the sidewall 212 of many hardness combined type rubber blanket 20 with respect to the one side that is provided with press section 211 (that is diagram sidewall 212 is following); The position that corresponds to cylinder 22 in substrate 40 is provided with hollow part 41; Be provided with the switch (not shown) in substrate 40 with respect to the one side that is provided with many hardness combined type rubber blanket 20 (that is bottom surface of diagram substrate 40), connecting structure 50 is arranged between keycap 30 and the substrate 40, in order to connect keycap 30 and substrate 40; Connecting structure 50 is a scissors pin connecting structure; Connecting structure 50 interlocks by two and first support 51 and second support 52 of pivot joint each other constitute, and the top of first support 51 and second support 52 is articulated in keycap 30 bottom surfaces, and the bottom of first support 51 and second support 52 is articulated in substrate 40; Keycap 30 supports maintenance one height by the body 21 of many hardness combined type rubber blanket 20; When pressing down keycap 30 with the strength that is parallel to the first direction F1 direction of substrate 40 (that is perpendicular to), can oppress body 21 distortion and cylinder 22 is sunk through the hollow part 41 of substrate 40, cylinder 22 can contact with the switch that is arranged at substrate 41 bottoms and touch switch electrically conducts; And when the pressure that acts on keycap 30 disappears; Keycap 30 can automatically return to original height by the elastic force effect of body 21, because the hardness of body 21 is lower, can bear that to push deformation ability higher; And the hardness of cylinder 22 is higher, for being used as power than higher of switch.
