It is through hole in it, in the middle part of upper lid, handle top is passed for pressing by through hole, and snap the line is provided with below the upper lid annular shell fragment,
Snap the line one end is fixed on base, and the other end is located at handle side arm, and corresponding handle side arm is provided with convex, guide ramp, handle
The fixing terminal on the descending contact base of annular shell fragment shell foot is driven to realize switch conduction when pushing, while also being driven by convex
Snap the line is descending, when being depressed into certain stroke, and snap the line departs from handle along the upward resilience of guide ramp, impacts and sends sound onto shell fragment
Sound.Keyboard with the slim switch in use can be because key switch sends sound and sends sound.Above-mentioned technology
The slim construction of switch that scheme is recorded, it has following not enough：1st, parts constitute many, complicated, cost of material and manufacture
Cost is high；2nd, on bottom upper guide post and guide pillar spring setting, its whole height is high, is unfavorable for slimming development；3rd, upper lid
Be arranged at provided with snap the line, i.e. snap the line in switch below annular shell fragment, at the same need corresponding handle side arm setting convex with
And guide ramp, make complicated, be unfavorable for general with existing switch.
Utility model content
The utility model provides one kind in the outer contact portion set at the top of elastic component, and elastic component and on keycap of switch
Bounce-back impact keycap, sends the slight keyboard of impact sound after contacting and being moved out, and it has, and simple in construction, cost is low, manufacture
The advantages of convenient and good tactile and sense of hearing.
The utility model can be achieved through the following technical solutions：
A kind of keycap carries the slight keyboard of contact portion, it is characterised in that including：
One bottom deck assembly, the bottom deck assembly includes circuit board and supporting plate；
Multiple buttons, the button is on the bottom plate；Each button is sequentially provided with from top to bottom：
One keycap, the keycap bottom side is provided with the contact portion for stretching out keycap body；
It is hollow bulb inside one scissor, the scissor, the upper pin of the scissor is connected with keycap body contacts, institute
The contact site on keycap is stated in the hollow part of scissor, the leftover bits and pieces of the scissor is connected with supporting plate；
One switch being connected with circuit board, the switch is thin film switch or fine motion mechanical switch；
One elastic component, the elastic component is placed in the scissor, and the elastic component at least includes contact site and one on one
Contacted at the top of lower rake, the upper contact site with the contact portion on keycap, the bottom of the elastic component is fixed on slight keyboard
On supporting plate on, contacted at the top of the upper contact site with the contact portion on keycap, during pushing, the lower inclination on elastic component
Portion is contacted with the leftover bits and pieces of scissor, and under contact portion and the extruding force got a foothold, elastic component is gradually moved inwards, until elastic component is complete
During total detachment contact portion, elastic component quick bounce-back in the presence of elastic force impacts keycap and sends impact sound upwards.
When pushing keycap, keycap body pressure switches, two contacts on switch respectively with two contacts on circuit board
Switch conduction is realized in contact.The principle of sound of slight keyboard of the utility model keycap with contact portion：When pushing keycap downwards,
Upper contact site on elastic component is contacted with the contact portion on keycap, during pushing, the lower rake of elastic component and elastic component
Get a foothold and contact, under contact portion and the extruding force got a foothold, elastic component is gradually moved inwards, until elastic component completely disengages from contact portion
When, elastic component quick bounce-back in the presence of elastic force impacts keycap and sends impact sound upwards.The utility model keycap carries contact
The slight keyboard in portion is mainly additionally arranged elastic component on the existing button with scissor leg structure, keycap be additionally arranged at the bottom of for by
The contact portion of compression elasticity part, and elastic component is arranged in scissor, the hollow bulb and keycap of scissor are passed through at the top of elastic component
On contact portion contact, the technical scheme is novel, unique structure；The technical scheme is located in switch by traditional elastic component
It is changed to be located at outside switch, i.e., elastic component is external in switch external, and its button pressed can send bounce-back sound, have button good
Good sense of touch and sense of hearing, it does not change the structure of existing button scissor, takes full advantage of existing product, is not increasing cost
On the basis of, make slight keyboard that there is good sense of touch and sense of hearing in use；The utility model keycap carries contact portion
Slight keyboard is the progress increase elastic component on the basis of existing membrane keyboard, and sets up on keycap contact portion, and by bullet
Property part is placed in scissor, and it does not change the structure of scissor, and its versatility is good；The utility model keycap is thin with contact portion
Type keyboard, relative to common key-press in the prior art switch in plus snap the line structure, in the prior art the increase of snap the line, it is necessary to
Handle side arm sets convex and guide ramp, and it needs that existing parts are modified and processed, and the utility model without
