Abstract

The utility model discloses a keyboard with luminescent characters, and the keyboard mainly includes a keyboard panel, transparent keys, luminescence pieces, a transparent median board, transparent spring components and a membrane switch. Guide holes are arranged on the transparent median board, the transparent keys are arranged on the guide holes of the keys of the transparent median board. The transparent keys and the transparent median board are fixed and arranged on the keyboard panel, the membrane switch is arranged under the transparent median board, and the luminescence pieces are arranged under the membrane switch. The key tops of the transparent keys are sprayed with an opaque coating, on which character icons can be engraved by laser; the luminescence pieces assume long sheet shapes, the luminescent area of the luminescence pieces take the guide holes of the keys on the transparent median board as centers, the length and the width correspond to the sizes of the tops of the keys. Compared with the conventional products, the utility model has less luminescent area, can overcome the defects that the prior keyboard has larger luminescent area and strong light rays, operator feels dazzled and uncomfortable after long-time usage, even the eyes of the operator can be hurt.

Description

A kind of character illuminated keyboard

Technical field

The utility model relates to a kind of keyboard that is applied to desktop computer or notebook computer, relates in particular to a kind of illuminated keyboard that still can normally use when insufficient light.

Background technology

Rapid development of computer technology also drives constantly bringing forth new ideas of ancillary equipment; Computer keyboard has had increasing improvement to its structure, function, profile etc., to satisfy the consumption grade that the consumer improves day by day as the important input equipment of computer.Illuminated keyboard promptly is the product under such trend, and it still can normally use under the situation of insufficient light.Present existing illuminated keyboard normally is provided with cold light (EL) sheet between button and keyboard case surface, make the cold light conductor on the cold light film luminous by the cold light drive circuit, realizes the function of illuminated keyboard.

But the defective of this illuminated keyboard is: luminous component is at the periphery of keyboard, and character not luminous (as Fig. 1-1, Fig. 1-2, Fig. 1-3).Because button is transparent, also printing opacity between button and the button, so visible light-emitting area is big, light is strong, makes the people feel dazzling and uncomfortable for a long time, and the eyes of harm people are arranged when serious.

The utility model content

The purpose of this utility model is to provide a kind of character illuminated keyboard, and the defective that it can overcome prior art provides the keyboard that character icon on a kind of button can printing opacity.

In order to achieve the above object, the technical scheme that the utility model adopted is: a kind of character illuminated keyboard, mainly comprise key panel, transparent push, cold light film, it is characterized in that: it also comprises transparent middle plate and thin film switch, plate is provided with the button guide hole in transparent, transparent push is located on the button guide hole of transparent middle plate, transparent push and transparent middle plate are fixedly arranged on the key panel, thin film switch is located under the transparent middle plate, cold light film is located under the thin film switch, sprayed a light tight dope layer on the key top of transparent push, light tight dope layer can carve the character icon behind laser engraving.

Described a kind of character illuminated keyboard, it also comprises the transparent elastic element, it is located under the transparent middle plate.

Described a kind of character illuminated keyboard, its cold light film is lengthy motion picture shape, and the luminous zone of cold light film is the center with the button guide hole of plate in transparent, and length and width are corresponding with the key-top size.

After adopting said structure, during use, after the transparent push surface lacquer is painted, be fixed on the transparent middle plate, after board component in the button is fixed on the key panel, this assembly is laid down transparent elastic element and thin film switch, thin film switch is laid thin shape cold light film down, thin film switch is transparent material and printed circuit, with the conducting push button signalling, cold light film needs by the drive circuit driven for emitting lights, after this structure keyboard is finished, sprayed paint button again by the laser engraving character on button, after keyboard connected the computer energising, cold light film was luminous and be radiated at the button inboard by plate in transparent, just can present the character illumination effect, compare with commonly using, this product of this product light-emitting area is little, and it is big to overcome existing light-emitting area, and light is strong, for a long time make the people feel dazzling and uncomfortable, the defective of the eyes of harm people is arranged when serious.

Embodiment

Please refer to shown in Fig. 4-11, the utility model provides a kind of character illuminated keyboard, mainly comprises key panel 1, transparent push 2, cold light film 3, transparent middle plate 4 and thin film switch 5, wherein:

Plate 4 is provided with button guide hole 41 in transparent, and transparent push 2 is located on the button guide hole 41 of transparent middle plate 4, and transparent push 2 and transparent middle plate 4 are fixedly arranged on the key panel 1, and thin film switch 5 is located at transparent middle plate 4 times, and cold light film 6 is located at thin film switch 5 times;

Sprayed a light tight dope layer 21 on the key top of transparent push 2, light tight dope layer 21 can carve the character icon behind laser engraving, because the button end face covers a light tight dope layer through spraying paint, so except that character icon 22, other positions of button are light tight, as shown in Figure 9.

Described a kind of character illuminated keyboard, it also comprises transparent elastic element 7, it is located at transparent middle plate 4 times.

Described a kind of character illuminated keyboard, its cold light film 6 is lengthy motion picture shape, and the luminous zone of cold light film 6 is the center with the button guide hole 41 of plate 4 in transparent, and length and width are corresponding with the key-top size.

During use, after transparent push 2 surface lacquers are painted, be fixed on the transparent middle plate 4, after board component in the button is fixed on the key panel 1, this assembly is laid transparent elastic element 7 (being generally silica gel) and thin film switch 5 down, thin film switch is laid thin shape cold light film 6 for 5 times, thin film switch 5 is transparent material and printed circuit, with the conducting push button signalling, cold light film 6 needs by the drive circuit driven for emitting lights, after this structure keyboard is finished, sprayed paint button again by the laser engraving character on button, after keyboard connected the computer energising, cold light film was luminous and be radiated at the button inboard by plate in transparent, just can present the character illumination effect.

The above for the person of ordinary skill of the art, can make other various corresponding changes and distortion according to the technical solution of the utility model and technical conceive, and all these changes and distortion all should belong to protection range of the present utility model.
