Description
Technical field
The present invention relates to the art of keypads of use for electronic products, particularly the integrated sealing elastic keyboard pad that uses of a kind of machine tool numerical control system.
Background technology
Along with technology development, the requirement of all trades and professions to machine tooling technology also improves constantly, machine tool numerical control system obtains develop rapidly, and various machine operation function is not quite similar, and this just requires that the various function define symbols of machine tool numerical control system guidance panel can be changed at any time or arrange.Traditional substitute mode is removed by the facial mask structure of whole to change, this concerning only need change individual feature key indicators mark situation, which complex operation, and whole facial mask structure is changed, easily cause the wasting of resources, its cost is also high, and meanwhile, a standardized product general operation function is also difficult to the needs of satisfied most of lathe.For this reason, the current button cap structure occurring replaceable mark, but this also has new requirement to the structure of keyboard, especially Keyboard pad, current structure as shown in Figure 1, Keyboard pad is by multiple key mat 1-1, the light-guiding pillar 2-1 that multiple high transmission rate material is made, protective sheet 3 and sealing gasket 4-1 form, first on keyboard, protective sheet is spread during use, then as required key mat and light-guiding pillar are fixedly got on one by one, and sealing gasket is set between protective sheet and keyboard, its assembling pole trouble when the Keyboard pad of this structure uses, product need be produced several times, manufacturing cost is too high, production manufacture there is a lot of resistances, meanwhile, in this structure, light-guiding pillar is solid construction, because light-guiding pillar is the leaded light being used to indicate lamp, therefore has very high requirement to its light transmittance, and this just makes its selection range very little, and material cost is high, and the light transmittance of light-guiding pillar also can not get improvement in essence.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, for machine tool numerical control system, provide a kind of and assemble the integrated sealing elastic keyboard pad simple, production cost is also low.
Technical scheme of the present invention is: a kind of integrated sealing elastic keyboard pad, comprise multiple key mat and multiple light-guiding pillar, multiple key mat and multiple light-guiding pillar are combined into one formula structure, and each key mat is positioned at corresponding keys upwards on keyboard, and each light-guiding pillar to be positioned on keyboard above corresponding indicator light.
Described light-guiding pillar is hollow-core construction, and one end that light-guiding pillar connects with indicator light is openend, and the other end of light-guiding pillar is blind end.
The end face of described blind end is plane.
The end surface thickness of described light-guiding pillar blind end is less than or equal to 0.8mm, and when ensureing that light-guiding pillar blind end can not occur breaking because of excessively thin, the end surface thickness of light-guiding pillar blind end should reduce as far as possible, can effectively improve its light transmittance.
The sidewall thickness of described light-guiding pillar is greater than the end surface thickness of light-guiding pillar blind end, and its inwall fineness should be high as far as possible.
Space in the middle part of described light-guiding pillar comprises and connecting successively and the open section communicated, straightway and optically focused section, open section is funnel-shaped structure, the bigger diameter end of open section is placed on indicator light, the miner diameter end of open section connects with straightway, the diameter of straightway and the miner diameter end equal diameters of open section, the diameter of optically focused section is less than straightway.
The junction of described optically focused section and straightway is provided with chamfering.
When Keyboard pad uses, the end face of light-guiding pillar blind end is as caustic surface, in conjunction with the hollow-core construction in the middle part of light-guiding pillar, in the light beam that indicator light sends, with light-guiding pillar axis being parallel and connect subparallel light direct projection to caustic surface, the light of the hollow inwall of directive light-guiding pillar after reflection simultaneously also directive caustic surface (sidewall of light-guiding pillar meets
wherein, z is sequence number, and λ is wavelength, and d is thickness, and n is refractive index, and α is incidence angle; When the fineness of light-guiding pillar inwall is higher, the reflectivity of light-guiding pillar sidewall is higher, and its light guide effect is also better), finally there is the light-ray condensing of sufficient intensity to transmit in caustic surface and reach guide-lighting object.
The cross section of described key mat is " 3 " shape, and the salient point at middle part contacts with button end face, and the convex surface of both sides arranges keycap, and the projection in the middle part of keycap is embedded in the groove at the salient point back side in the middle part of key mat.
Above-mentioned integrated sealing elastic keyboard pad also comprises sealing strip, and sealing strip is located at the periphery of multiple key mat and multiple light-guiding pillar.
The material of Keyboard pad is transparent rubber, also can adopt the transparent thermoplastic elastomer such as polystyrene, olefin-based, ester system, polyurethane system, acrylate or ethene system.
When this integrated sealing elastic keyboard pad manufactures, arrange each key mat and each light-guiding pillar according to the actual needs of keyboard, then adopt the technique one-shot forming Keyboard pad of conventional rubber compression moulding or thermoplastic elastomer (TPE) injection moulding.When this integrated sealing elastic keyboard pad uses, Keyboard pad is fixed on keyboard according to the distribution of button on keyboard and indicator light, then on corresponding key mat, keycap and identification cover is installed.
The present invention, relative to prior art, has following beneficial effect:
Multiple part combination is integral type structure by this integrated sealing elastic keyboard pad, can adopt traditional compression moulding or Shooting Technique one-shot forming during manufacture, effectively simplifies its manufacturing process, reduces manufacturing cost; As a part during use, overcome conventional keys plate mat number of parts numerous, loaded down with trivial details defect is installed, this integrated sealing elastic keyboard pad is easy to use.
In addition, multiple key mat, light-guiding pillar and sealing gasket are combined into one by this integrated sealing elastic keyboard pad, can save protective sheet, save material, and it also avoid the possibility coordinating between each part and occur gap, its sealing effectiveness is better simultaneously.
In this integrated sealing elastic keyboard pad, light-guiding pillar is hollow-core construction, and can effectively improve its light-conductive rate, selection range also can be expanded, and is conducive to reducing production cost.
