Abstract
The utility model relates to a light-guiding sheet and a keyboard thereof. The light-guiding sheet comprises a high luminousness plastic sheet body, the upper surface of which is provided with a plurality of projections formed by light-curing glue materials and the lower surface of which is provided with ink layers which one by one correspond to the projections and function to guide light, the keyboard which is applied in the light-guiding sheet can be provided with projection structure on the plastic sheet body of the light-guiding sheet and the projection is directly used for the alignment of a convex switch of a main board, thereby key structures with different forms, in particular the key with flat bottom can be adopted. The light-guiding sheet also avoids the problems of misplacement and more time consumption occurring during the alignment assembly of the projection block of the key and the convex switch of the main board in the prior art, etc., and effectively simplifies the assembly technique and improves the assembly efficiency.
Description
Technical field
The present invention relates to the keyboard of a kind of light guide sheet and application thereof, it is widely used in electronics and communication product field, as cell phone keyboard, household electrical appliance keyboard etc.
Background technology
As shown in Figure 1, disclose a kind of cell phone keyboard structure, wherein, this cell phone keyboard structure is by formations such as button 1 ', light guide sheet 2 ' and mainboards 3 ', and this light guide sheet 2 ' plays translucent effect between button 1 ' and mainboard 3 '; This mainboard 3 ' is provided with a plurality of convex switches 31 ', and traditional light guide sheet 2 ' is made by plastic sheet usually, its upper and lower faces is the smooth flat shape, therefore, above-mentioned button 1 ' must be provided with the projection 11 ' that corresponding one by one keyboard mainboard 3 ' is gone up each convex switch 31 ' towards light guide sheet 2 ' that face, so as can shape touch convex switch 31 ' on the mainboard 3 ' effectively.So during as if the desire assembling, be separated with under the situation of light guide sheet 2 ' on the one hand, finding mainboard 3 ' accurately and go up corresponding convex switch 31 ' contraposition meeting and have difficulties, so not only can inconsistent phenomenon occur and cause defective products to take place because of this projection 11 ', also very consume man-hour simultaneously, production efficiency is low; The then smooth shape design in the two sides of traditional light guide sheet 2 ' on the other hand selects that certain limitation is arranged for the shape of button 1 ', and for example plane button can't be suitable for, and to sum up all factors are given to produce in the industry and brought certain puzzlement.
Summary of the invention
The present invention is directed to the existing disappearance of above-mentioned prior art, main purpose is to provide the keyboard of a kind of light guide sheet and application thereof, wherein, help the assembling of keyboard, and can select multi-form press-key structure to cooperate again by the design that forms prominent point on the light guide sheet.
For realizing above-mentioned purpose, the present invention takes following technical scheme:
A kind of light guide sheet comprises that the plastic cement lamellar body of a high transmission rate, the upper surface of this plastic cement lamellar body are provided with the prominent point that a plurality of smooth solidity colloidal materials form, and is provided with one by one dashing forward a little and playing the ink lay of leaded light effect at the lower surface of this plastic cement lamellar body.
A kind of made keyboard of above-mentioned light guide sheet of using, comprise button, light guide sheet and mainboard, this light guide sheet is between button and mainboard, this mainboard is provided with a plurality of convex switches, this light guide sheet comprises the plastic cement lamellar body of a high transmission rate, it is characterized in that: the upper surface of this plastic cement lamellar body is provided with the prominent point of the light solidity colloidal materials formation of each convex switch on the corresponding one by one keyboard mainboard, and should dash forward point and convex pairs of switches; And be provided with one by one dashing forward a little and playing the ink lay of leaded light effect at the lower surface of this plastic cement lamellar body.This button is provided with keycap; This button is plane structure towards light guide sheet.
The present invention compared with prior art, its advantage is as follows: design bump structure on the plastic cement lamellar body by light guide sheet, make this prominent point directly can therefore can select multi-form press-key structure to cooperate, be applicable to that especially the bottom is flat button for the convex pairs of switches of mainboard; It has been avoided in the prior art convex switch by the projection of button and mainboard and has carried out dislocation that the contraposition assembly brings, consuming time etc. disappearance, and simplified assembling process improves packaging efficiency effectively.
Description of drawings
Fig. 1 is a prior art keyboard schematic diagram;
Fig. 2 is the utility model schematic cross-section;
Fig. 3 is the schematic diagram of keyboard of the present invention.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described.
See also shown in Figure 2ly, a kind of light guide sheet comprises a plastic cement lamellar body 10, and this plastic cement lamellar body 10 is formed through cutting through mold injection molding or with the plastic sheet of ready-made high transmission rate by the plastic material of high transmission rate, wherein:
The upper surface 11 of this plastic cement lamellar body 10 is provided with the prominent point 12 that a plurality of smooth solidity colloidal materials form, should can adopt injection light solidity colloid in the moulding hole of mould earlier by prominent point 12 manufacturing process, then plastic cement lamellar body 10 is laid on the moulding hole top of this mould,, the demoulding solid through roll-in, light forms; Be provided with one by one dashing forward a little 12 and play the ink lay 14 of leaded light effect at the lower surface 13 of this plastic cement lamellar body 10, this ink lay 14 can strengthen the light conductivity of plastic cement lamellar body 10, and the mode that it can adopt silk-screen or bat printing is not limited at this.
As Fig. 3, a kind of keyboard of using above-mentioned light guide sheet comprises light guide sheet, button 20 and mainboard 30, is provided with keycap 21 on this button 20, wherein:
This light guide sheet is between button 20 and mainboard 30, this mainboard 30 is provided with a plurality of convex switches 31, this light guide sheet comprises the plastic cement lamellar body 10 of a high transmission rate, the upper surface 11 of this plastic cement lamellar body 10 is provided with a plurality of prominent points 12 that formed by light solidity colloidal materials, should prominent point 12 be that each convex switch 31 position is arranged on the corresponding one by one mainboard 30, and should dash forward point 12 and convex switch 31 each artoregistration; Lower surface 13 at this plastic cement lamellar body 10 is provided with a plurality of ink laies 14 that play the leaded light effect, and it is one by one 12 positions of should dashing forward a little to be arranged that this oil is put layer 14, and contacts with above-mentioned convex switch 31.This button 20 is plane structure towards light guide sheet, and then during pressing keys 20, impels the prominent point 12 of light guide sheet to press down by button 20, realizes the purpose that keyboards are pushed by convex switches 31 that this prominent point 12 touches mainboards 30.
