According to button described in the utility model, these projections are incorporated into bolster in hot melt pressing mode.
According to button described in the utility model, the keycap periphery is extended with marginal ridge, and each projection is upwards protruded out by this marginal ridge respectively, and this bolster is arranged at the end face of this marginal ridge.Further, marginal ridge is to go out from this keycap root edge horizontal-extending.
According to button described in the utility model, the bolster surface has the protruding lip that raises up.Further, the height of protruding lip is greater than the height of projection with this projection after bolster combines.
According to button described in the utility model, each projection is protruded out downwards by keycap respectively.Further, the bolster bottom surface has recess, and each projection is contained in this recess, and as the support of this bolster.
For reaching above-mentioned purpose, low noise push-button of the present utility model is applied to keyboard, keyboard is made up of substrate, loam cake and a plurality of button, and each button is set at respectively in a plurality of accommodation spaces of loam cake, each button all is made up of keycap and bolster, this keycap can be done upper and lower motion with respect to this substrate, and this keycap periphery convexes with most projections, and in the sheathed bolster of keycap periphery, and corresponding each projection of this bolster has perforation respectively, makes each projection pass each perforation back and combines with this bolster.
By this, each bolster can be made respectively with keycap again and be combined, and be easy to make and reduce the effect of making this and can reach, and each button touches by bolster and loam cake, and can reduce noise.
The preferably, this keycap is made by thermoplastic, and the mode of these projection mat hot melt pressings and combining with this bolster.
The preferably, this keycap periphery horizontal-extending has marginal ridge, and each projection is upwards protruded out by this marginal ridge respectively, and this bolster is arranged at the end face of this marginal ridge.
The preferably, this bolster surface has the protruding lip that raises up, and each projection is with after this bolster combines, the height of this protruding lip is greater than the height of each projection.
The preferably, each projection is protruded out downwards by this keycap respectively, and this bolster bottom surface correspondence has recess, be contained in this recess after making each projection and this bolster combining, and as the support of this bolster.
The preferably, this bolster is made by flexible material, as elastomeric material.
The preferably, when this button was in no pressed state, this bolster contacted with this loam cake.
Keycap of the present utility model and bolster all can be made separately in a large number, and processing procedure is simple, more can effectively reduce manufacturing cost.Moreover the employed bolster of the utility model can be made suitable shape, thickness according to required, and then reaches best noise-decreasing and the effect that promotes comfort.

Embodiment
For making the purpose of this utility model, structure, feature and function thereof there are further understanding, cooperate now graphic the utility model preferred embodiment to be described in detail as follows.
See also Fig. 1 to Fig. 3, Fig. 1 is the schematic diagram of keyboard of the present utility model, and Fig. 2 is the sectional structure schematic diagram of 2-2 hatching line among Fig. 1, and Fig. 3 is the sectional structure schematic diagram of keycap of the present utility model and bolster.
Keyboard 1 of the present utility model includes substrate 11, loam cake 12 and a plurality of button 2.This loam cake 12 is arranged on this substrate 11, and this loam cake 12 is laid with plurality of openings 121, and has accommodation space 122 respectively be provided with for each button 2 between each opening 121 and this substrate 11.
Each button 2 is arranged at respectively respectively in this accommodation space 122, and each button 2 all is made up of keycap 21, supporting mechanism 22 and bolster 23.
This keycap 21 is made by thermoplastic, and this keycap 21 is incorporated on this supporting mechanism 22, and this supporting mechanism 22 is arranged on the substrate 11, make this keycap 21 do upper and lower motion with respect to this substrate 11, and these keycap 21 periphery horizontal-extendings have marginal ridge 211, and upwards protruded out several projections 212 in marginal ridge 211 peripheries, for this bolster 23 in conjunction with being provided with.
This bolster 23 is made by flexible material (as: elastomeric material), it is sheathed on the end face of this marginal ridge 211, and these bolster 23 corresponding each projections 212 have perforation 231 respectively, each projection 212 can be passed respectively bore a hole 231, shown in the left side of Fig. 3, and each projection 212 is combined with this bolster 23 by the mode of hot melt pressing, shown in Fig. 3 right-hand part, these bolster 23 peripheries have the protruding lip 232 that raises up again, and the height of the projection 212 of the height of this protruding lip 232 after greater than the hot melt pressing, make button 2 when no pressed state, can contact with the bottom surface of this loam cake 12 by the protruding lip 232 of bolster 23.
Owing to bolster 23 of the present utility model and keycap 21 are to combine by hot melt pressing mode, therefore keycap 21 all can be made separately in a large number with bolster 23, see through simple hot melt pressing program again keycap 21 is combined with bolster 23, and do not need as prior art, to use the twice ejaculating forming processing procedure or the coating processing procedure that sprays paint.Thus, not only processing procedure is simple, more can effectively reduce manufacturing cost.
Moreover, the employed bolster 23 of the utility model is because of by the combination of hot melt pressing mode, so can comply with required suitable shape, the thickness made, allow button 2 be pressed and during by the elastic returning of supporting mechanism 22, can touch loam cake 12 by bolster 23, absorb the strength of clashing into material behavior, and then reach best noise-decreasing and the effect that promotes comfort by bolster 23.
Please consult Fig. 4 again, it is the keycap of another embodiment of the utility model and the sectional structure schematic diagram of bolster.Wherein, these keycap 41 peripheries have protruded out most projections 411 downwards, and the bottom surface of this bolster 43 has recess 432, each projection 411 is passed respectively bore a hole and be arranged in this recess 432 at 431 o'clock, shown in the left side of Fig. 4, and each projection 411 is housed inside in this recess 432 after by the hot melt pressing, shown in the right-hand part of Fig. 4, and as the support of this bolster 43.So also can reach the effect identical with previous embodiment.
