See also shown in Fig. 3 and Fig. 4, combination cross-sectional schematic respectively of the present utility model and combination are overlooked and illustrated
Figure, wherein Fig. 4 represents in a perspective fashion.This utility model is mainly in above-mentioned first connecting rod part 30 and the one of substrate 1 phase joining place
Side, is extended with a first support bar 302 being resisted against on substrate 1, and above-mentioned second connecting rod part 31 and the one of keycap 2 phase joining place
Side, then be extended with one and be resisted against the second support bar 312 on keycap 2.Described first and second support bar 302,312 is all located at and light
At the adjoining side in source 11, use the intensity deficiency supplied at cutting assemblies 3 facing light sources 11, this light source of simultaneously still can dodging
11 setting and do not affect its due original function, the other assemblies that more need not additionally increase.
Further, described first support bar 302 can be by the side of first connecting rod 30 and first time convergence part 300 and
Extend in one " l " font between convergence part 301 on one, and be resisted against on this substrate 1 by the one end in " l " font；And it is described
Second support bar 312 also can by convergence part 311 on the side of second connecting rod part 31 and second time convergence part 310 and second between be in one
" l " font is extended, and is resisted against on this keycap 2 by the one end in " l " font.
Specifically, first support bar 302 may include one first joining section 302a and one first supporting section 302b, and this first
Joining section 302a and this first supporting section 302b respectively along two directions configurations being generally perpendicular to each other, with framework go out described in be in
The extension of " l " font.First joining section 302a is in order to be connected the first frame side 303 extending in different directions and first time convergence part
300, and the pivoted hole 304 from this first frame side 303 for the first supporting section 302b is adjacent to the side of first time convergence part 300
And extend, and it is resisted against on this substrate 1 by the free end of the first supporting section 302b.Through these configuration, this first frame side 303 or
First time convergence part 300 needn't occupy the space of light source 11 top.Additionally, along different directions configuration the first joining section 302a and
First supporting section 302b may be used to maintain the balance of first connecting rod part 30, and to supply the through supporting of the first supporting section 302b
Intensity at one link member 30 facing light sources 11 is not enough.
From the above, second support bar 312 may include one second joining section 312a and one second supporting section 312b, and this second
Joining section 312a and this second supporting section 312b respectively along two directions configurations being generally perpendicular to each other, with framework go out described in be in
The extension of " l " font.Second joining section 312a is connected with second in order to be connected the one second frame side 313 extending in different directions
Portion 311, and the drive-connecting shaft 314 from this second frame side 313 for the second supporting section 312b is adjacent to one of convergence part 311 on second
Side and extend, and be resisted against on this keycap 2 by the free end of the second supporting section 312b.Through these configurations, this second frame side 313
Or convergence part 311 needn't occupy the space of output optical zone 21 lower section of keycap 2 on second.Additionally, configure along different directions second
Joining section 312a and the second supporting section 312b may be used to maintain the balance of second connecting rod part 31, and through the second supporting section 312b's
Support the intensity to supply at second connecting rod part 31 facing light sources 11 not enough.
From the above, first support bar 302 and first connecting rod part 30 can form one first avoidance opening 305, and second
Strut 312 and second connecting rod part 31 form one second avoidance opening 315, and the light being provided for light source 11 first is kept away via this
Allow opening 305 and this second avoid mouth 315 and be radiated at the output optical zone 21 of keycap 2.Embodiment as depicted, first support bar
302 and first time convergence part 300 form this first avoidance opening 305, in second support bar 312 and second, convergence part 311 is formed
This second avoidance opening 315.
Thereby, the light that the light source 11 being arranged on base plate 10 is launched can't be subject to the first connecting rod part of cutting assemblies 3
30 are covered with second connecting rod part 31, and can smoothly be delivered to keycap 2.Meanwhile, existing such as gimbal lever etc. component can be saved.This
Outward, described first and second support bar 302,312 also can be projected into plastic material one in this first and second link member 30,31 respectively
Type.
In an embodiment, the set location of first support bar 302 corresponds to the set location of second support bar 312, such as
Shown in Fig. 2.The keycap that is pressed down drive first and second link member 30,31 lie flat during, second support bar 312 can be along
The lifting direction of keycap and draw close toward first support bar 302；In the state of first and second link member 30,31 is lain put down completely, second
Support bar 312 can drop in first support bar 302 and be subject to supporting of first support bar 302, use raising cutting assemblies 3
Stationarity.In an embodiment, the face shaping of the face shaping of first support bar 302 and second support bar 312 can be mutual
Cooperation (fitting).In an embodiment, the thickness (keycap lifts the size on direction) of first support bar 302 can be less than
The thickness on the first frame side 303, and the thickness of second support bar 312 can be less than the thickness on the second frame side 313.Thereby, shears group
The gross thickness of part 3 needn't increase, and is beneficial to the slimming application of button.
Therefore by above-mentioned contexture, you can obtain this utility model press-key structure.
Therefore, by press-key structure of the present utility model, it utilizes original cutting assemblies 3, on corresponding position
It is provided with two support bars (i.e. first support bar 302 and second support bar 312) being resisted against button substrate 1 and keycap 2 respectively, with mat
Substrate 1 can be supported respectively with keycap 2 at intensity deficiency of facing light sources 11 by two support bars, so make keycap 2 be subject to by
Still can steadily make upper and lower reciprocating motion during pressure, will not excessively take the confined space under keycap 2 simultaneously, there will not be increase material
The problems such as material cost.
In sum, the actually rare new creation product of this utility model, its really can reach expected from use mesh
, and solve existing disappearance, and because of great novelty and creativeness, comply fully with utility application important document, hence according to
Patent Law is filed an application, please detailed survey grant quasi- this case patent, to ensure the right of inventor.
But the foregoing is only preferable possible embodiments of the present utility model, non-therefore arresting limits patent of the present utility model
Scope, therefore such as change with the equivalent structure that this utility model description and accompanying drawing content are done, all it is contained in this in the same manner
In the scope of patent protection of utility model.
