Embodiment
Refer to Fig. 1 to Fig. 3, Fig. 1 is a schematic perspective view of thin keypressing structure of the present invention, Fig. 2
And Fig. 3 be thin keypressing structure of the present invention in the exploded perspective view on different directions.First sketch first
Relative overlying relation between each element of the present invention.Thin keypressing structure 1 of the present invention includes a positioning
Frame lid 11, a keycap 12, pliability carrying lamellar body 13, a circuit board 14 and a bottom plate 15.
Pliability carrying lamellar body 13 has defined a void region 13a, and keycap 12 is stacked and placed on pliability carrying lamellar body
On 13, and keycap 12 covers void region 13a part or void region 13a whole.Circuit board
14 are arranged at the lower section of keycap 12 and pliability carrying lamellar body 13, can be connect when being moved down for keycap 12
It is butted on circuit board 14.Posting lid 11 is located at the top of thin keypressing structure 1, and bottom plate 15 is positioned at thin
The bottom of type press-key structure 1, and the common tug of the folder up and down keycap 12 of posting lid 11 and bottom plate 15,
Pliability carries lamellar body 13 and circuit board 14.
Fig. 4 is a diagrammatic cross-section of thin keypressing structure of the present invention, and please refer to Fig. 2 to Fig. 4.
Specifically, circuit board 14 has a switch shrapnel 141, and switch shrapnel 141 is formed at circuit board 14
A upper surface 140.Keycap 12 pushes protruded stigma 122 and once ring peripheral part 123 including one, pushes
Protruded stigma 122 extends downwardly from a bottom surface 120 of keycap 12, and passes engraving for pliability carrying lamellar body 13
Dummy section 13a.Wherein, push protruded stigma 122 and be formed at the middle section of keycap 12, and push protruded stigma
122 position alignment is in the switch shrapnel 141 of circuit board 14.It is switch shrapnel 141 to need expositor in this
Can be a metal clips, be typically otherwise known as metal dome.Thus, keycap 12 is pushed by a user
When, push protruded stigma 122 and fit to compress switch shrapnel 141.After the user discharges keycap 12, switch
Shell fragment 141 then pushes up back pushing protruded stigma 122 and making keycap 12 return back to an initial position for keycap 12.Remove
Outside this, the lower ring peripheral part 123 of keycap 12 is formed at the border area of keycap 12, and keycap 12
Smoothly it is carried on its lower ring of ring peripheral part 123 week on pliability carrying lamellar body 13, and keycap
12 do not have the phenomenon that relaxation is rocked.
For the relation that can be seen clearly that between subelement structure, Fig. 5 saves for thin keypressing structure of the present invention
Slightly illustrate positioning frame body and pliability carrying lamellar body a schematic perspective view, and please refer to Fig. 2,
Fig. 3 and Fig. 5.Furthermore, keycap 12 also includes at least one first snap fit 121, from lower ring week
Edge 123 is downwardly projected to be formed.Bottom plate 15 is arranged at the lower section of circuit board 14, and bottom plate 15 includes
At least one second snap fit 151 projected upwards.At least one second snap fit 151 of bottom plate 15 upwardly extends prominent
Go out and sequentially penetrate circuit board 14 an at least wears groove 142 and pliability carrying lamellar body 13 at least one
Breach 132, engaged with least one first snap fit 121 with keycap 12.Specifically, keycap 12
At least one first snap fit 121 is formed outwardly after extending downwardly protrusion from the lower ring peripheral part 123 of keycap 12
One first kink 121a.At least one second snap fit 151 of bottom plate 15 upwardly extend it is prominent after it is curved inwardly
Folding forms one second kink 151a, and the first kink 121a snap fits are in the second kink 151a, by
This is as the structure for limiting the relative displacement between keycap 12 and bottom plate 15.
Posting lid 11 is arranged at the surface of pliability carrying lamellar body 13, and posting lid 11 includes one
Ring wall 111 and the spacing perforation 112 of one defined is surrounded by ring wall 111, keycap 12 is worn positioned at spacing
Hole 112 and part be revealed in it is outer, to be pressed for user pressure.Ring wall 111 has plural number positioning prick post
113, wherein, positioning prick post 113 penetrates pliability carrying lamellar body 13 and circuit board 14, and and bottom plate
15 engagements, to fix.More specifically, there is pliability carrying lamellar body 13 positioning of plural number first to wear
Hole 135, circuit board 14 have plural second positional punch 145, and there is bottom plate 15 plural number the 3rd to position
Perforation 155, and each positioning prick post 113 of posting lid 11 is each sequentially arranged in corresponding one first
Positional punch 135, one second positional punch 145 and one the 3rd positional punch 155, and position and wear
Post 113 is fixed in the 3rd positional punch 155, thus makes between each element of thin keypressing structure 1 mutually
Close-stacked is fixed.
In addition, bottom plate 15 also includes at least protruding part 152, at least a protruding part projected upwards
152 upwardly extend the prominent wears groove 143 for penetrating circuit board 14, are pulled with top and carry lamellar body 13 in pliability,
And an at least protruding part 152 is arranged at intervals with least one second snap fit 151, thus with fifty-fifty support upwards
Play pliability carrying lamellar body 13.
On the other hand, the material of pliability carrying lamellar body 13 be preferably selected from a braiding elasticity dry goods, one can
Flexible material or an elastomeric material.Its shape is preferably a ring-type lamellar body, i.e., pliability carrying tablet in structure
Body 13 has an Inner peripheral portions 131, and Inner peripheral portions 131 define void region 13a.Also, key
Cap 12 is preferably a plastic cement keyboard, and then carry and be connected to can for the peripheral part of ring once 123 of keycap 12
The Inner peripheral portions 131 of flexible carrier sheet body 13, that is, support while pliability carrying 13 ring week of lamellar body formula is presented
The form of keycap 12.
And because pliability carrying lamellar body 13 connects as one with keycap 12, therefore one is formed in overall structure
Barrier layer, the barrier layer can shield external foreign matter and drop from top to bottom into circuit board 14, therefore with anti-
The dust-proof effect of water.Further, since with the presence of a clearance G between posting lid 11 and keycap 12, and
Outside pliability carrying lamellar body 13 can be revealed in by clearance G, therefore manufacturer's alterable pliability carrying tablet
The color of body 13 and make integral product that special outward appearance be presented.
In summary, thin keypressing structure of the present invention carries lamellar body ring week ground uniformly carrying key by pliability
Cap, make each keycap putting stable and being not easy to have swag phenomenon in itself, and then lift user and grasping
Feel on work.Also, thin keypressing structure of the present invention need not device scissor and/or rubber key, make
Obtain button thickness thin type.In addition, pliability carrying lamellar body is combined as a whole therefore can completely cut off with keycap
Circuit board 14 is fallen to from the foreign matter of top, the antidrip effect of dirt of more strengthening defences.
Above-described embodiment is only the principle and its effect of the illustrative present invention, and explains the present invention's
Technical characteristic, not for the protection category of the limitation present invention.Any those skilled in the art can be not
, can unlabored change or the arrangement of isotropism in the case of the technical principle and spirit of running counter to the present invention
Belong to the scope that the present invention is advocated.Therefore, the right that the scope of the present invention should be as be described hereinafter
Listed by it is required that.
