Abstract
The invention discloses a structure of a notebook computer glowing keyboard, comprising a base plate, a light guide plate, a flexible circuit board, silica gel keys, scissor kicks and keycaps, wherein the light guide plate is fixed on the base plate, the flexible circuit board is fixed on the upper layer of the light guide plate by virtue of a hook of the base plate, the front or back of the flexible circuit board is printed with shading printing ink, the silica gel keys are directly adhered on the flexible circuit board, the keycaps are connected with the base plate by virtue of the scissor kicks, the back of the flexible circuit board is adhered with an LED light used for providing a light source for the light guide plate, the front of the light guide plate is provided with reflective printing ink spots, and the back of the light guide plate is provided with a reflective layer which enhances reflection of light. In the invention, the LED light adhered on the back of the flexible circuit board is utilized to provide a luminescent light source for the light guide plate, and the shading printing ink on the surface of the flexible circuit board is utilized to realize good shielding effect, thus the original keyboard design is simplified, and the materials of backlight plates, power circuits, shading sheets and the like in the original keyboard design are reduced.
Description
Technical field
The present invention relates to a kind of notebook computer field, be specifically related to a kind of structure of notebook computer illuminated keyboard.
Background technology
The keyboard if desired of existing keyboard of notebook computer is luminous, basically be to adopt the flexible circuit board (FPC) of metal base to add that illuminating source (paster LED lamp) adds auxiliary material such as light guide plate, be attached to the common keyboard back side, not only cost is higher, and thickness that has increased keyboard powers separately Yin Xu Give illuminating source, and computer main board also needs module to provide power supply and link position for it, has also taken the design space of mainboard in varying degrees.
Summary of the invention
The objective of the invention is in order to overcome the existing defective of illuminated keyboard on keyboard thickness, cause notebook computer to realize the spatial limitation of ultrathin design, provide a kind of and can realize that keyboard of notebook computer is luminous, but do not increase keyboard thickness, do not take mainboard space and resource, and can save a kind of new construction design of a large amount of auxiliary material and operation.
The technical solution used in the present invention is: a kind of structure of notebook computer illuminated keyboard, comprise substrate, light guide plate, flexible circuit board, silica gel push-button, scissors pin and keycap, described light guide plate is fixed on the substrate, flexible circuit board is fixed in the light guide plate upper strata by the grab of substrate, flexible circuit board front or back up have black out ink, silica gel push-button directly sticks on the flexible circuit board, keycap is connected with substrate by the scissors pin, the back side of described flexible circuit board is pasted with and is used to light guide plate that the LED lamp of light source is provided, described light guide plate front is provided with reflective printing ink spot, and the light guide plate back side is provided with increases reflective reflector layer.
As preferably, described substrate adopts aluminium sheet or iron plate.
As preferably, described light guide plate adopts hot melting mode to be fixed on the substrate.
As preferably, described reflector layer is white ink or minute surface silver or reflecting piece.
The present invention obtains moving up and down of keycap by the rotation of scissors pin, silica gel push-button utilizes glue to be fixed on the flexible circuit board, flexible circuit board and light guide plate fix by the mechanism on the substrate, flexible circuit board front or back up black ink, be used for interception, to be used to light guide plate to provide the LED lamp of light source to be bonded at the flexible circuit board back side, there is the reflective printing ink spot that has in the light guide plate front, back side adularescent printing ink or minute surface silver, be used to increase reflective, if the back side not the also available one deck reflecting piece of printing-ink replace.
Beneficial effect: the present invention directly is positioned over light guide plate on the keyboard substrate, the LED lamp source of utilizing the flexible circuit board back side to paste provides illuminating source for light guide plate, and the black out ink of utilizing the flexible circuit board surface realizes good shaded effect, simplified original keyboard Designing mode, reduced the backlight on original keyboard Designing, power circuit, materials such as anti-dazzling screen, the components and parts that computer main board is used to provide power supply have simultaneously also been reduced, and can avoid to obtaining the keyboard of notebook computer lighting function, the notebook computer thickness that increases out, thus be that realization notebook computer ultrathin design is given security on the keyboard spare part.
