Description

Character luminescent waterproof keyboard and preparation method thereof

Technical field

The present invention relates to a kind of electronic product, relate in particular to a kind of character luminescent waterproof keyboard and preparation method thereof.

Background technology

Along with development of electronic technology, as electronic equipments such as computer a large amount of apply to daily life, in the work, and to the control of computer, the signal input mainly realizes by keyboard, do not doubt so the importance of keyboard is ccontaining, but common keyboard does not have the characteristics of luminescence now, so at night or insufficient light the time, operation keyboard is extremely inconvenient, more obvious to the computer beginner, for improving the convenience of operation keyboard when the insufficient light, a kind of character luminescent waterproof keyboard had appearred afterwards, this character luminescent waterproof keyboard is provided with light tiles below keyboard, the light tiles issued light comes out by the slit between each keyboard, but the illumination effect of this character luminescent waterproof keyboard is undesirable, still can't see clearly each keyboard on symbol, the beginner uses still inconvenient; Simultaneously, the sealing of existing computor-keyboard is poor, has influence on the flexibility and the accuracy of keyboard operation most probably because dust, water enter keyboard, and even more serious is, and keyboard can not use and scrap.

Summary of the invention

The object of the present invention is to provide a kind of character luminescent waterproof keyboard and preparation method thereof, this character luminescent waterproof keyboard has the better characteristics of luminescence, more convenient operation to keyboard.

The present invention is achieved through the following technical solutions:

A kind of character luminescent waterproof keyboard comprises panel, base plate, is provided with conducting film between panel and base plate, and conducting film is connected with circuit board, and panel is provided with keyboard, is provided with light tiles below keyboard, but this keyboard is a luminous button.

Among the present invention, keyboard is luminous under the irradiation of light tiles, the light that is produced directly appears from keyboard, with respect to prior art, the better effects if that it is luminous, in insufficient light, user's a glance just can be seen the pairing key symbols of a certain keyboard clearly, uses more convenient.

Further improvement of the present invention is:

Be provided with diaphragm seal, lower sealing piece between described panel and the base plate, last diaphragm seal, lower sealing piece are with described circuit board, conducting film and light tiles sealing.In keyboard, be provided with diaphragm seal the current-carrying part of keyboard is sealed, avoid dust, water etc. to enter keyboard and flexibility and accuracy when having influence on, the useful life of improving keyboard keyboard operation.Described upward diaphragm seal is the switch elastic membrane, and this switch flexible sheet produces output signal by pressing described conducting film.The switch elastic membrane is made by full wafer silica gel, can not have structures such as through hole, slit on it, should guarantee good sealing property.

Described upward diaphragm seal is the light-permeable diaphragm seal, and described light tiles is a sheet, is located at described going up between diaphragm seal, the lower sealing piece.This structure can improve lower sealing piece, the lower sealing piece sealing effectiveness to light tiles, and at this moment, last diaphragm seal should have translucent effect, be beneficial to light from last diaphragm seal to the keyboard transmission.

Described light tiles is located at below the described conducting film and with described circuit board and is connected.Light tiles directly is arranged under the conducting film, makes compact conformation.

Light tiles of the present invention is by making keyboard luminous to the keyboard transmission, and concrete structure can be: described light tiles is that EL cold light film, LED lamp or LED lamp are luminous by optical material or reflectorized material, and described keyboard is a transparent push.Promptly send light by light tiles, and shine on the keyboard, the transparent position of keyboard sheds light.

Further, the present invention is by electronic circuit control light intensity and auto sleep, with visual effect and the energy-saving effect that guarantees.

A kind of manufacture method of character luminescent waterproof keyboard, this method may further comprise the steps at least:

A, employing transparent material processing keyboard;

B, cover at the keyboard upper surface and to pick up photosphere;

C, the photosphere of picking up on its surface is partly removed and formed hyalomere by the symbol of each keyboard representative;

D, each keyboard, conducting film, circuit board and panel after will processing, base plate are installed and the formation keyboard.

To sum up, advantage of the present invention is:

1, keyboard is luminous, and for the slit between the keyboard in the existing technology was luminous, its illumination effect was better, more convenient operation during use;

2, by last diaphragm seal, lower sealing piece conducting film is sealed, after water, dust enter keyboard, can avoid keyboard to scrap or damage;

3, upward diaphragm seal, lower sealing piece play sealing function to light tiles simultaneously;

4, the light power can be adjusted, and cuts off the power supply automatically when not using.

Embodiment

Embodiment one:

See also Fig. 1, Fig. 2, a kind of character luminescent waterproof keyboard, comprise panel 1, base plate 2, between panel 1 and base plate 2, be provided with conducting film 3, conducting film 3 is connected with circuit board 4, panel 1 is provided with keyboard 5, be provided with light tiles 6 (light tiles 6 is the LED lamp) below keyboard 5, but this keyboard 5 is a luminous button.

Wherein, be provided with diaphragm seal 7 (going up the switch elastic membrane of diaphragm seal 7 for being made by the full wafer silica gel material), lower sealing piece 8 between panel 1 and base plate 2, conducting film 3 constitutes signal generating circuit for multilayer; Light tiles 6 is a sheet, is located between diaphragm seal 7, the lower sealing piece 8, more precisely, is located at conducting film 3 times and is connected with circuit board 4; Last diaphragm seal 7 is the light-permeable diaphragm seal, last diaphragm seal 7, lower sealing piece 8 are with conducting film 3, circuit board 4, light tiles 6 sealings, keyboard 5 is the light-permeable button, and 9 outside transmissions through the transmittance section, wherein, (symbol shown in the figure is M, just illustrates for the symbol on the keyboard 5 transmittance section 9, other keyboard printing opacity mode is identical therewith), remainder is light tight.

Last diaphragm seal 7 is last diaphragm seal, with lower sealing piece 8 light tiles 6, conducting film 3, circuit board 4 are sealed, make present embodiment have sealing property better, play the waterproof and dustproof effect, in use, light tiles 6 can be sent light, sees through conducting film 3, upward shines on the keyboard 5 after the diaphragm seal 7, outwards luminous by the transmittance section 9 on the keyboard 5 again, when insufficient light, use more convenient.
