Abstract
The invention discloses a touch key-press light guide structure. The touch key-press light guide structure comprises a touch screen, a shell, a light-emitting diode which is arranged on a circuit board, and a light guide sheet which comprises a character-shaped light transmitting part and a non-light transmitting part and is arranged between the touch screen and the light-emitting diode. The provided touch key-press light guide structure is simple in structure, and easy and convenient to assemble; and a light guide column structure is eliminated, and a hot melting injection molding process and other processes are not needed to be adopted, so that the production cost can be effectively reduced by more than 50 percent. By arranging scattering points, the uniform light transmitting effect can be achieved by an electronic equipment designing company under the condition that change and die repairing are not needed to be considered.
Description
Technical field
The present invention relates to electronic communication field, refer more particularly to the structural design of electronic equipment.
Background technology
Along with the development of electronic communication, people use electronic equipment in increasing occasion.Work as night, during on every side without environment light source, the button of electronic equipment is difficult for identification.Button or the membrane keyboard of character backlight have occurred in the market having, the user relies on the character identification button that gets final product backlight, prevents maloperation.In prior art, usually adopt the mode of hot melt light-guiding pillar on housing, as shown in Figure 1,11 is touch-screen, and 112 is two-sided gum, and 13 is housing, and 14 is the housing hot molten column, and 15 is light-guiding pillar, and 16 is LED, LIGHTEMITTING DIODE lamp, and 17 is PCB.The shortcoming of this kind structure has: 1. complex structural designs, and need to increase a light-guiding pillar die sinking and also do hot melt, material need be selected optics PC, and cost is higher.2. need to increase toner or increase one deck diffusion barrier in light-guiding pillar, guaranteeing the printing opacity uniformity, seeing otherwise the LED lamp easily sees through the character of touch-screen.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, the touch key-press light guide structure of being convenient to assemble.
Touch key-press light guide structure provided by the present invention comprises touch-screen, housing and is arranged on Light-Emitting Diode on circuit board; Also comprise light guide sheet, described light guide sheet is provided with character shape transmittance section and non-transmittance section, and described light guide sheet is arranged between described touch-screen and light emitting diode.
Described housing is provided with locating dowel; Be provided with locating hole in the position corresponding with described locating dowel on described light guide sheet.Described light guide sheet comprises light guiding film and gum layer.Described housing is provided with flange, and described light-guiding pillar is arranged on described flange.Described housing is provided with flange, and described light guide sheet is bonded on described flange by described gum layer.Be provided with scattering point on described light guiding film, the density of described scattering point and its distance apart from described Light-Emitting Diode are inversely proportional to.Described locating dowel and locating hole are 2.
Touch key-press light guide structure provided by the present invention, simple in structure, assemble easyly, not only omitted light guide column structure, need not to adopt the techniques such as hot-melting and injection-molding, can effectively reduce production costs more than 50%.By the setting of scattering point, electronic device design company need not to consider change and repairs a die to realize uniform translucent effect.

Fig. 2 is light guide sheet locating hole schematic diagram;
Fig. 3 is touch key-press light guide structure schematic diagram of the present invention.
The specific embodiment
For the purpose, technical scheme and the advantage that make the embodiment of the present invention clearer, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
As shown in Figure 3, the touch key-press light guide structure that the present embodiment provides comprises touch-screen 31, housing and is arranged on Light-Emitting Diode (LED, LIGHT EMITTING DIODE) 35 on circuit board 36; Also comprise light guide sheet 32, described light guide sheet 32 is provided with character shape transmittance section and non-transmittance section, and described light guide sheet 32 is arranged between described touch-screen 31 and light emitting diode 35.It will be understood by those skilled in the art that the light that described Light-Emitting Diode (LED, LIGHT EMITTING DIODE) sends, can appear by described character shape transmittance section, thereby make described character have effect backlight.Use described light guide sheet 32, need not to arrange light-guiding pillar again, structure is simpler, has saved hot melt and die sinking that light-guiding pillar is set, and manufacture craft is more succinct, and cost is lower.
As shown in Figure 3, described housing is provided with locating dowel 34; As shown in Figure 2, be provided with locating hole 21,22 in the position corresponding with described locating dowel 34 on described light guide sheet 32.When it will be understood by those skilled in the art that assembling, as long as being plugged in, locating dowel 34 can realize being fixedly installed described light guide sheet 32 in described locating hole 21,22.
Described light guide sheet 32 comprises light guiding film (LGF, LIGHT GUID FILM) and gum layer.Described gum layer is used for bonding described light guide sheet 32 and housing.
Described housing is provided with flange 33, and described light-guiding pillar is arranged on described flange 33; Described light guide sheet 32) be bonded on described flange 33 by described gum.So more be convenient to fixing described light guide sheet 32, structure is more stable.
Be provided with scattering point on described light guiding film (LGF, LIGHT GUID FILM), the density of described scattering point and its distance apart from described Light-Emitting Diode (LED, LIGHT EMITTING DIODE) are inversely proportional to.Namely apart from Light-Emitting Diode (LED, LIGHT EMITTING DIODE) position far away, its light a little less than, need light transmittance higher, less scattering point need be set; Otherwise apart from the nearer position of Light-Emitting Diode (LED, LIGHTEMITTING DIODE), its light is stronger, needs light transmittance lower, and more scattering point need be set.By regulating the density of diverse location scattering point, just can realize the even technique effect of translucent effect like this.Need not as prior art, increase toner or increase diffusion barrier in light-guiding pillar, guarantee the printing opacity uniformity.
Described locating dowel and locating hole are 2, and structure is more firm.
It should be noted that at last: above embodiment only in order to technical scheme of the present invention to be described, is not intended to limit; Although with reference to previous embodiment, the present invention is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme that aforementioned each embodiment puts down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of various embodiments of the present invention technical scheme.
