Abstract

The utility model discloses a keyboard structure of a laptop, which comprises a baseplate, a flexible printed circuit board with a keystroke function, a silica gel keystroke, scissors feet and a keycap, wherein the silica gel keystroke is directly adhered on the baseplate; the keycap is connected with the baseplate through the scissors feet; the flexible printed circuit board is arranged below the baseplate; and position-shunt holes used for assembling a computer are formed on the flexible printed circuit board. According to the keyboard structure provided by the utility model, the flexible printed circuit board with the keystroke function is arranged at the bottom of the baseplate, so that mechanism holes to match with key position mechanisms are not required to be formed on the flexible printed circuit board, and the number of the mechanism holes is greatly reduced, as a result, the circuit board is simpler to manufacture. The keyboard structure integrates a light guide plate and a circuit board, a conductive circuit used for realizing the keystroke function is arranged on the light guide plate, LED lamps used for providing light sources are also adhered on the light guide plate, so that a back-light plate, a power circuit, a light-proof plate and other materials of an original keyboard are reduced, and at the same time, the components of the computer main board, which are used for providing the power supply, are reduced.

Description

A kind of structure of keyboard of notebook computer

Technical field

The utility model relates to a kind of notebook computer field, is specifically related to a kind of structure of keyboard of notebook computer.

Background technology

The FPC with keypress function of existing keyboard of notebook computer is attached to above the keyboard metal base, and the mechanism hole of fit key position mechanism need be set, because the mechanism hole is more, makes the making more complicated of wiring board.

Keyboard is luminous if desired must stick on module backlight for existing keyboard of notebook computer; Module backlight is to adopt the FPC (FPC) of metal base to add that illuminating source (paster LED lamp) adds auxiliary material such as LGP, is attached to the common keyboard back side, and not only cost is higher; And increased the thickness of keyboard; Give illuminating source because of need and supply power separately, it is that it provides power supply and link position that computer main board also needs module, has also taken the design space of mainboard in varying degrees.

As shown in Figure 1: the FPC 1 that existing illuminated keyboard structure is the button effect is installed in above the substrate 2, and the back side of substrate 2 is provided with LGP 3, and silica gel push-button 4 directly sticks on the FPC 1, and keycap 6 is connected with substrate 2 through scissors pin 5.

Summary of the invention

The purpose of the utility model is to be installed in the deficiency on the substrate in order to overcome the prior art FPC; A kind of structure of keyboard of notebook computer is provided; This structure also can overcome the defective of illuminated keyboard on keyboard thickness, has solved notebook computer and has realized the ultrathin spatial constraints that designs, and can reduce keyboard thickness; Do not take mainboard space and resource, and can save a large amount of auxiliary material and operations such as FPC.

The technical scheme that the utility model adopts is: a kind of structure of keyboard of notebook computer; Comprise substrate, have FPC, silica gel push-button, scissors pin and the keycap of keypress function; Said silica gel push-button directly sticks on above the substrate; Said keycap is connected with substrate through the scissors pin, and said FPC is arranged on below the substrate, and FPC is provided with a hole of keeping away that is used to assemble computer.

Because a hole of keeping away that cooperates assembling screw hole on computers and so on only is set on the FPC, the mechanism hole of fit key position mechanism is not set, simplify the circuit cabling, thereby reduce spillage of material, the light decay of avoiding LGP mechanism hole to cause more.

As preferably, said substrate adopts aluminium sheet, iron plate or alloy sheets.

As preferably, said FPC is provided with LGP and forms leaded light circuit module, is pasted with on this leaded light circuit module the LED of light source is provided lamp.

As preferably; Positive reflector layer and the light shield layer that adopts the two-layer printing ink of black and white to be formed by stacking of said leaded light circuit module, ground floor is a white, is used for LGP is returned in the light generation diffuse reflection of LGP; Cover one deck black above the white; Be used to prevent that light from seeing through white ink and being mapped to the outside, leaded light circuit module reverse side adopts the luminescent layer of silver color or bright silver-colored printing ink, and the light that is used for LGP is reflective.

Beneficial effect: the utility model is because the FPC of button effect is arranged at base plate bottom; A hole of keeping away that cooperates assembling screw hole on computers and so on only is set; Because the mechanism hole of fit key position mechanism need be set; So significantly reduced the mechanism hole, made the making of wiring board oversimplify more.

The utility model makes wiring board have an opportunity to combine or do not combine with LGP because the FPC of button effect is arranged at base plate bottom, can more comprehensively consider the feasibility that it is frivolous.

The utility model can be integrated LGP and wiring board; On LGP, be provided with the conducting wire of realizing keypress function; And have stickup that the LED lamp of light source is provided, and, increase luminescent layer at reverse side in positive reflector layer and the light shield layer of increasing of leaded light circuit module; But and directly utilize the emitting components of body directly illuminating source to be provided for LGP; Reduced materials such as backlight on original keyboard Designing, power circuit, anti-dazzling screen, also reduced computer main board simultaneously and be used to provide the components and parts of power supply, and can to avoid be to obtain 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.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is described further:

As shown in Figure 2: a kind of structure of keyboard of notebook computer; Comprise substrate 2, have FPC, silica gel push-button 4, scissors pin 5 and the keycap 6 of keypress function; Said silica gel push-button 4 directly sticks on above the substrate 2; Said keycap 6 is connected with substrate 2 through scissors pin 5, and said FPC is arranged on below the substrate 2, and FPC is provided with a hole of keeping away that is used to assemble computer.

Said substrate 2 adopts aluminium sheet, iron plate or alloy sheets.

Said FPC is provided with LGP and forms leaded light circuit module 7, is pasted with on this leaded light circuit module 7 LED of light source is provided lamp.Said leaded light circuit module 7 positive reflector layer and the light shield layers that adopt the two-layer printing ink of black and white to be formed by stacking, leaded light circuit module 7 reverse side adopt the luminescent layer of silver color or bright silver-colored printing ink.
