Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, but does not limit protection range of the present utility model and range of application:
As shown in Figures 1 to 4, a kind of membrane keyboard, comprise the metallic plate 1, conductive film 2 and the button 3 that arrange from the bottom up, the compressible bracing or strutting arrangement 32 that described button 3 comprises keycap 31 and is arranged on below keycap 31, the upper end of described bracing or strutting arrangement 32 is connected with the bottom surface of keycap 31, lower end is connected with described metallic plate 1, described conductive film 2 is provided with the first through hole 21 at bracing or strutting arrangement 32 and the junction of metallic plate 1, the shell fragment 4 with stable resilience force is provided with, to obtain good pressing feel above described conductive film 2.Preferably, described shell fragment 4 is metal clips or nonmetal shell fragment.Wherein metal clips can be stainless steel shell fragment, aluminium alloy shell fragment etc., and nonmetal shell fragment can silica gel shell fragment, rubber shell fragment etc.Be provided with flexible glue 5 above described shell fragment 4, to increase pressing stroke, preferably, described flexible glue 5 is the one in silica gel, rubber, TPU, to have the good elasticity of compression.TPU material, TPU is the abbreviation of ThermoplasticUrethane, Chinese is TPUE, and TPU is by the macromolecular material of the vulcabond quasi-molecules such as '-diphenylmethane diisocyanate (MDI) or toluene di-isocyanate(TDI) (TDI) and macromolecular polyol, the common reactive polymeric of low molecular polylol (chain extender).Its molecular structure is that the soft segment that the hard block and the diisocyanate molecules such as '-diphenylmethane diisocyanate (MDI) or toluene di-isocyanate(TDI) (TDI) that are obtained by reacting by '-diphenylmethane diisocyanate (MDI) or toluene di-isocyanate(TDI) (TDI) and chain extender and macromolecular polyol are obtained by reacting alternately is formed.TPU has remarkable high-tension, high-tensile strength, tough and ageing-resistant characteristic, is a kind of environment-friendly materials of maturation.Preferably, described flexible glue 5 is cylindricality flexible glue, such as cylinder, cuboid or polygonal body etc., has and presses stroke preferably.The corresponding flexible glue 5 of described bracing or strutting arrangement 32 is provided with second through hole 33 that can pass for flexible glue 5, and when pressing keycap 31 to bracing or strutting arrangement 32 and being compressed to minimum, described keycap 31 contacts with described flexible glue 5, and described shell fragment 4 contacts with conductive film 2.
When push button 3 keycap 31 time, bracing or strutting arrangement 32 is subject to the pressure effect of keycap 31 and compresses, when being compressed to minimum, keycap 31 contacts with flexible glue 5 and acts on flexible glue 5, flexible glue 5 is made deformation and displacement to occur and act on shell fragment 4, there is deformation effect on conductive film 2 in shell fragment 4, thus circuit turn-on, produce input signal; When keycap 31 active force reduces or eliminate, shell fragment 4 and flexible glue 5 return to the original form due to deformation effect, and bracing or strutting arrangement 32 supports keycap 31 and returns to original position, thus completes the motion of one-period, and structure is simple, practical feature.
The membrane keyboard of the present embodiment, please refer to Fig. 1 to Fig. 4, the basis of previous technique scheme can be specifically, described bracing or strutting arrangement 32 is scissor, described scissor comprises scissor housing 321 and scissor inside casing 322, the top of the inside casing 322 of described scissor housing 321 and scissor is articulated and connected with the bottom surface of described keycap 31 respectively, the lower end of the inside casing 322 of described scissor housing 321 and scissor is hinged with metallic plate 1 respectively, the hinged place of the corresponding scissor of described conductive film 2 and metallic plate 1 is provided with the first through hole 21, the corresponding flexible glue 5 of described scissor inside casing 322 is provided with second through hole 33 that can pass for flexible glue 5.
Scissor leg structure also claims X structure full name to be called SCISSOR, its operation principle is: use two groups of parallel four-bar linkages, allow during four corner of user by touching dish in forced movement mode and can enjoy smooth and easy and consistent feel, the plastic-steel material of lightweight, firm in structure, durability is better than general keyboard.It is the two groups of bar linkage structure bracing frames that have employed similar scissors shape between keycap 31 and rubber blanket, key journey is generally about about 2.50mm ~ 3.0mm, key journey is very short, this design client depresses from the corner of keycap 31 and the finger of user all can be allowed stressed on keycap 31 equably, when pressing the corner of keycap 31, the point at center can be triggered, i.e. keycap 31 corner feel and electrically good.Keycap 31 is stablized, can not be rocked.Each button 3 all can obtain same feel, uses quiet little, can not have influence on other people.When push button 3 keycap 31 time, scissor is subject to the pressure effect of keycap 31 and compresses, when being compressed to minimum, keycap 31 contacts with flexible glue 5 and acts on flexible glue, make flexible glue 5 that deformation occur and displacement acts on shell fragment 4, shell fragment 4 deformation effect is on conductive film 2, thus circuit turn-on, produce an input signal, when keycap 31 active force is eliminated or reduce, shell fragment 4 and rubber 5 return to the original form due to deformation effect, and scissor supports keycap 31 and returns to original position, thus completes the motion of one-period.Described bracing or strutting arrangement 32 can also reach and the finger of user can be allowed stressed on keycap 31 equably, other structures that keycap 31 is stablized, can not be rocked, the such as button 3 of volcanic crater, palace rod structure.
The membrane keyboard of the present embodiment, the basis of previous technique scheme can be specifically, and whole described flexible glue 5 is formed in one, production technology can being reduced when producing, reducing production cost, can the set-up time be reduced when carrying out keyboard assembling simultaneously, be convenient to procedure for producing assembling, reduce cost.
More than that the utility model membrane keyboard is set forth; the utility model is understood for helping; but execution mode of the present utility model is not restricted to the described embodiments; any do not deviate from the utility model principle under do change, modification, substitute, combination, simplify; all should be the substitute mode of equivalence, be included within protection range of the present utility model.
