It is as follows to describe the utility model in detail below in conjunction with embodiment and accompanying drawing thereof;

As Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5, a kind of notebook computer keyboard device of the present utility model, it includes a keycap 10, an elasticity is touched body 20, one first support 30, one second support 40, a pedestal 50 and a base plate 60 and constituted, keycap 10 wherein is the cap body of a square, its end face and bottom surface form an operating surface 111 and a fitting surface 12 respectively, and this fitting surface 12 is provided with two pivot holes 13 and two chutes 14.

Elasticity touch part 20 is located at keycap 10 belows, and between keycap 10 and pedestal 50, elasticity touch part 20 is positioned between the stroke of keycap 10 starts.

First support 30 and second support 40 are arranged between the fitting surface 12 and pedestal 50 of keycap 10, partly be provided with corresponding pivot 31 and pivot hole 41 in the middle of first support 30 and second support, 40 both sides, make this two stands 30 and 40 be articulated into the interlinked mechanism that cross-like is provided with.Upper end, first support, 30 both sides respectively is provided with a pivot 32, upper end, second support, 40 both sides respectively is provided with a slide-bar 42, this two stands 30,40 nationality respectively makes first support 30 and second support, 40 upper ends be linked to the fitting surface 12 of keycap 10 by pivot hole 13 and chute 14 that the pivot 32 and the slide-bar 42 of both sides upper ends articulated and be snug fit at keycap 10.First support 30 and lower end, second support, 40 both sides respectively are provided with a pivot 33,43, can be linked on the pedestal 50 in order to pivot joint.The pivot 33 of lower end, the utility model at least one support 30 both sides protrudes from the lateral wall 34 and the rear wall (or front side wall) 35 of this support 30, make the rear wall 35 of this support 30 and pivot 33 the inners between form the angle 36 that without exception is inverted L shape.

Pedestal 50 is located at keycap 10, first support 30 and second support, 40 belows, is preset with most perforation 51,52 on the pedestal 50, and these perforation 51,52 are corresponding with first support 30 and lower end, second support, 40 both sides pivot 33,43.First support 30 and lower end, second support, 40 both sides pivot 33,43 articulate and are linked in the perforation 51,52 default on the pedestal 50, and these perforation 51,52 tops respectively are provided with a spacer 53,54, in order to limit the displacement that pivot 33,43 makes progress.Pedestal 50 is provided with an accommodation space that runs through up and down 55, and this first support 30 and second support 40 are positioned at accommodation space 55 tops, can be in order to ccontaining this two stands 30 and 40.

Base plate 60 is located at pedestal 50 belows, and is provided with a FPC 70 between base plate 60 and pedestal 50, on this FPC 70 and the base plate 60 and be provided with and first support 30 and 33, the 43 corresponding perforation 71,61 of lower end, second support, 40 both sides pivot.

It is parallel up and down when mobile that keycap 10 is done by two stands 30,40 guiding, and the elasticity of keycap 10 belows is touched body 20 can press or leave FPC 70, makes switch do ON or OFF action.When keycap 10 interlock two stands 30,40 move down, this two stands 30,40 can sink in accommodation space 55, so can be under the constant principle of key stroke, the thickness of keycap 10 can be reduced, reduce the height of button integral body, and accommodation space 55 can provide first support 30 and second support 40 function by the assembling of pedestal 50 belows.

When the pivot 33 of lower end, the utility model support 30 both sides was articulated in the perforation 51 of pedestal 50, the volume of these pivot 33 major parts can sink the people in the perforation 51 that is articulated, so can make the height of button integral body significantly reduce.Moreover, but the pivot 33 mat spacers 53 of this lower end, support 30 both sides provide the block effect to top offset, when the pivot 33 of this lower end, support 30 both sides during to bottom offset, the angle 36 of this pivot 33 can be matched with perforation 61 medial margins of this base plate 60, and can be along these 61 medial margin slippages of boring a hole, the pivot 33 of this lower end, support 30 both sides can provide the block effect to bottom offset by this, nationality so that this support 30 in Z axle (upper and lower) direction have good location.But lateral wall 34 mat spacers 53 inboards of first support 30 provide the block effect of left and right displacement, so that the block effect of left and right displacement to be provided, the angle 36 of this pivot 33 can be matched with perforation 61 medial margins of this base plate 60, the block effect of left and right displacement also can be provided, make support 30 have good location in X-axis (left and right) direction, make keycap 10 when doing upper and lower motion, comparatively stable, can not produce left and right rocking.Again, but the block effect that the pivot 33 nationality spacers 53 of these support 30 lower ends and pilot hole 51 provide forward and backward displacement, make support 30 have good location in Y-axis (forward and backward) direction, therefore support 30 all can have good location in three direction of principal axis, makes being articulated on the pedestal 50 that two stands 30 can be stable.

In sum, the utility model is a rare novel creation product in fact, has novelty and progressive, meets novel patented claim important document fully, likes to file an application according to Patent Law, would like to ask detailed survey and grants accurate this case patent.

The above only is a preferable possible embodiments of the present utility model, is not to be used to limit the utility model.
