Description

Overlay keyboard unit

technical field

The invention relates to a covering keyboard device, in particular to a backlit keyboard comprising a plurality of independent keycaps and a plurality of independent covering layers.

Background technique

The well-known backlit keyboard is often used with notebook computers. When the backlight function of the backlit keyboard is turned on in the dark, the white light-emitting diodes (LEDs) inside the keyboard will emit light, which will emerge from the laser-engraved characters above each keycap, so that the user can clearly see the keyboard. characters on. When in bright places, the LEDs in the backlit keyboard will be turned off to save power. Therefore, the backlit keyboard works well at night or in the dark. Conversely, non-backlit keyboards do not emit light. However, in order for the backlit keyboard to make the characters formed by laser engraving transparent, and the other parts of the keycap to be opaque, it is necessary to bake many layers of paint back and forth on the transparent keycap body, up to ten layers at most, so that the It is opaque and wear-resistant. Then, laser engraving is used to remove the baking varnish on the characters on the top of the keycap, so that light can be transmitted through the characters.

However, the above-mentioned process of repeatedly baking up to ten layers of paint on the keycap body requires a lot of time and cost. Therefore, how to improve the conventional process so as to save the related manufacturing cost and time and make the light radiating from the characters uniform is a problem worth pondering.

For this reason, in view of the lack of prior art, the inventor thought about the idea of improving the invention, and finally was able to invent the "covered keyboard device" in this case.

SUMMARY OF THE INVENTION

The main purpose of this case is to provide a covering keyboard device, so that the keycaps provided on the keyboard are not only more beautiful and feel better than the keycaps of the conventional keyboards, but also make the related manufacturing costs more conventional because it does not need to bake paint. The backlit keyboard is low, and the related manufacturing time is shorter than that of the conventional backlit keyboard, and the light radiating from the characters on the keycap is formed into a uniform light band.

Another main object of the present application is to provide a covering keyboard device, which includes a plurality of independent keycaps, wherein each of the keycaps includes a body, and a cover layer, which is attached to the body and includes a fabric layer and a cover layer. It is suitable for a primer layer of the fabric layer, wherein a character is formed on the upper surface of one of the fabric layers, and the primer layer includes a transparent material and an opaque coloring material, and the coloring material is mixed with the The material is used to adjust the color of the characters visible to the naked eye, and a light emitted from the inside of the overlay keyboard device is scattered or reflected or refracted to form a uniform light band due to the color material.

Another main purpose of the present application is to provide a covering keyboard device, which includes a plurality of independent keycaps, wherein each of the keycaps includes a body, and a cover layer, which is attached to the body and includes a fabric layer and a cover layer. A base material layer suitable for the material layer, wherein a character is formed on an upper surface of the material layer, and a light emitted from the inside of the overlay keyboard device is scattered or refracted by the base material layer Or reflect a uniform light band.

Detailed ways

1 is a cross-sectional view showing a keycap according to a preferred embodiment contemplated by the present invention. The covering keyboard device proposed by the present invention includes a plurality of independent keycaps, wherein each of the keycaps includes a body and a covering layer. In FIG. 1 , the keycap 1 includes a body 11 having a top surface 111 , and a cover layer 12 , wherein the cover layer 12 includes a material layer 121 and a bottom material layer (or an adhesive layer) 122 . A thermoplastic layer (or a light diffusing layer) 126 and an adhesive layer 127 . The cover layer 12 is at least covered on each of the relevant top surfaces 111 of the respective main bodies 11, wherein each of the cover layers 12 has a lower surface 124 attached to the top surface 111, and an upper surface 125 ( That is, an upper surface of the fabric layer 121 ), after removing the fabric layer 121 on the upper surface 125 by laser engraving, a character 123 is formed. After the cover layer 12 is attached to the body 11 , the characters 123 are located above the top surface 111 , and the plurality of cover layers 12 of the keyboard are independent of each other.

The characteristics of the present invention are: the above-mentioned fabric layer 121 is rubbed at least 100 times by an alcohol abrasion test, a test with a soft eraser abrasion test at least 100,000 times, and a test with a hard eraser abrasion test. After rubbing for at least 1,000 times, the face material layer 121 is still not peeled off (or: a frame around the character 123 is intact after the above three abrasion tests). The fabric layer 121 does not peel off after the above three abrasion tests, which depends on the molecular size, coating thickness and texture design of the fabric layer 121 . In general, larger molecules are more wear-resistant, and thicker coatings are more wear-resistant. For example, it is known to those with ordinary knowledge in the art that when carbon black particles are added to rubber to generate a reinforcing effect on the rubber, carbon black with larger particles has better wear resistance. For another example, it is known to those with ordinary knowledge in the art that a composite floor includes a transparent material (abrasion-resistant layer), a printed fabric and a base material. The thickness of the wear-resistant layer is related to the wear resistance of the floor. For example, general offices or places with more people, such as restaurants, department stores, and storefronts, must use plastic floor tiles with thicker wear-resistant layers. In addition, those with ordinary knowledge in the art know that when the tread of the automobile tire is a transverse groove tread, the driving force, braking force and traction force are excellent, and the wear resistance is good.
