A kind of cover type key board unit, include multiple independent keycaps, wherein each keycap includes an ontology, an and coating, it posts in the ontology and includes a precoat and fit in one of precoat initial bed, wherein one of described precoat upper surface forms a character, and one of sending light is in uniform by scattering due to the initial bed from inside the cover type key board unit.
Description
Technical field
The present invention relates to a kind of cover type key board unit, espespecially a kind of includes multiple independent keycaps and multiple independent coverings
The backlight keyboard of layer.
Background technique
Known backlight keyboard, laptop of often arranging in pairs or groups use.When backlight keyboard opens backlight function in the dark,
The light emitting diode (LED) of keyboard to emit white light will issue light, saturating from the character above each keycap through laser carving
Out, so that user is clear that the character on keyboard.When the LED in Liang Chu, backlight keyboard will be closed, to save electricity
Power.Therefore, backlight keyboard is at night or dark place operates very well.And on the contrary, non-backlight keyboard is then not irradiative.But
It is that backlight keyboard is in order to make light transmission at the character formed through laser carving, and the other parts of keycap are opaque, it is necessary in light transmission
Keycap ontology on baking vanish plurality of layers back and forth, at most can baking vanish to ten layers, keep its opaque and wear-resisting.It then, then will with laser carving
Baking vanish at the character of keycap top removes, and enables to appear light at the character.
However, above-mentioned up to ten layers of baking vanish of the processing procedure repeatedly on keycap ontology, need to spend many manufacturing times and cost.
Therefore, this known processing procedure how is improved, to save related manufacturing cost and time, and makes the light appeared from the character
It is a problem worth thinking deeply about in uniform.
Duty is event, and inventor is the idea for thinking and improveing invention, can invent this case eventually in view of the missing of known techniques
" cover type key board unit ".
Summary of the invention
The main purpose of this case is to provide a kind of cover type key board unit, so that each keycap set on the keyboard
The keycap of more conventional keyboard is not only beautiful and soft handle, and because need not baking vanish due to keep related manufacturing cost more conventional backlight keyboard
Low, the more conventional backlight keyboard of related manufacturing time is short, and one of makes to appear light at character from keycap in a homogeneous bands.
The another main purpose of this case is to provide a kind of cover type key board unit, includes multiple independent keycaps, wherein respectively
The keycap includes an ontology and a coating, posts in the ontology and includes a precoat and fit in the fabric
One of layer initial bed, wherein forming a character in one of precoat upper surface, the initial bed includes a transparent material
With an opaque colorant, the colorant mixes the material, to adjust the character can by the color of a finding of naked eye, and
One of sending light is scattered because of the colorant or reflects or reflect in a uniform light from inside the cover type key board unit
Band.
Another main purpose of this case is to provide a kind of cover type key board unit, includes multiple independent keycaps, wherein respectively
The keycap includes an ontology and a coating, posts in the ontology and includes a precoat and fit in the fabric
One of layer initial bed, wherein forming a character in one of precoat upper surface, and from inside the cover type key board unit
One of sending light is scattered or is reflected because of the initial bed or reflected in a homogeneous bands.
Detailed description of the invention
In order to above-mentioned purpose of the invention, feature and advantage can be clearer and more comprehensible, preferred embodiment is cited below particularly, and
Cooperate institute's accompanying drawings, be described in detail below:
Fig. 1: it is the sectional view of the keycap for the preferred embodiment for showing that one conceives according to the present invention.
Fig. 2: it is the top view of the keycap of the keyboard for the preferred embodiment for showing that one conceives according to the present invention.
Specific embodiment
Fig. 1 is the sectional view of the keycap for the preferred embodiment for showing that one conceives according to the present invention.Proposed by the invention covers
Lid formula key board unit, including multiple independent keycaps, wherein each keycap includes an ontology and a coating.It is described in Fig. 1
Keycap 1 includes one of one top surface 111 of tool ontology 11 and a coating 12, wherein the coating 12 includes a precoat
121,122, one thermoplastics type of an initial bed (or an adhesion coating) layer (or spreading layer of a light) 126 and an adhesive layer 127.Institute
It states coating 12 and at least posts each correlation top surface 111 in each correlation ontology 11, wherein each coating 12
It (is also the upper table of one of described precoat 121 that tool a lower surface 124, which fits in the top surface 111 and a upper surface 125,
Face), after the precoat 121 through being removed at the upper surface 125 with laser carving according to font, form a character 123.It is covered when described
Cap rock 12 posts after the ontology 11, and the character 123 is located at the described of 111 top of the top surface and the keyboard
Multiple coatings 12 are independently of one another.
The invention has the characteristics that the as described above precoat 121 through an alcohol abrasion test rub at least 100 times,
One test wipes abrasion test friction at least 100,000 times with soft rubber and wipes abrasion test friction at least 1,000 times with test vulcanite
Afterwards, the precoat 121 still (presses down without removing or is: around one of the character 123 frame through three kinds of above-mentioned wear-resisting experiments
After be complete).The precoat 121, still without removing, is to depend on the precoat 121 by three kinds of above-mentioned abrasion tests
Molecular size, coating layer thickness and its lines design.In general, more wear-resisting when molecule is larger, and when coating is thicker,
Also more wear-resisting.For example, this field tool common sense person knows, carbon black particle is added in rubber to generate the reinforcement to rubber
When effect, the carbon black of larger particle has preferable wearability.For another example, tool common sense person in this field knows, composite wood floor packet
Containing transparent material (wearing layer), printing fabric and bottom material.And the thickness relationship of wearing layer is to the wearability on floor, seems generally to handle official business
Room or the more discrepancy place of the crowd just have to the plastic floor tile with thicker wearing layer such as dining room, department store, StoreFront.Separately
Outside, tool common sense person in this field knows, when the tread of automobile tire is traverse furrow tread, then its driving force, brake force and leads
Gravitation is excellent, and its wearability is good.
The alcohol abrasion test above-mentioned is rubbed with an alcohol cotton, and one of described alcohol cotton alcohol is dense
Degree is selected from by one of formed group of 75%, 95% and 99%, and the test soft rubber, which wipes abrasion test, to be made
