Abstract
The utility model discloses a luminous keyboard structure of a notebook computer, which comprises a base plate, a light guide plate, a flexible printed circuit board, silicon rubber keys, scissor legs and keycaps. The luminous keyboard structure of the notebook computer is characterized in that the light guide plate is fixed on the base plate, the flexible printed circuit board is fixed at the upper layer of the light guide plate through clamping hooks, reflective ink is arranged on the front surface of the flexible printed circuit board, the silicon rubber keys are directly bonded on the flexible printed circuit board, the keycaps are connected with the base plate through the scissor legs, light emitting diode (LED) lamps which are used for providing light sources to the light guide plate are bonded on the back surface of the flexible printed circuit board, two layers of ink are arranged on the front surface of the light guide plate, the bottom layer of ink is white or mirror silver and is used for increasing reflection, and the upper layer of ink is black and is used for shading light in upward direction. By changing the original front flat panel design of the light guide plate into the design with mechanism holes, by adding a reflective layer and a light shading layer on the front surface of the light guide plate and by adding a luminous layer on the front surface of the flexible printed circuit board, materials for a backlight panel, power supply lines, light shading pieces and the like in the original keyboard design are reduced.
Description
Technical field
The utility model relates to a kind of notebook computer field, is 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 purpose of this utility model is in order to overcome the existing defective of illuminated keyboard on keyboard thickness, cause notebook computer to realize the space constraint 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 adopted in the utility model 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, the flexible circuit board front is provided with reflective printing 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, there is two-layer printing ink in described light guide plate front, bottom printing ink is to be used to increase reflective white or minute surface silver, and upper strata printing ink is the black that is used for upward to shading.
As preferably, described substrate adopts aluminium sheet or iron plate.
As preferably, offer the mechanism hole of fit key disc mechanism on the described light guide plate.
Beneficial effect: the utility model changes the original positive slab design of light guide plate into have the mechanism hole design, and in positive reflector layer and the light shield layer of increasing of light guide plate, at the positive luminescent layer that increases of flexible circuit board, but and directly utilize the emitting components of flexible circuit board body directly to provide illuminating source for light guide plate, 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.
