Embodiment

In order to make technical problem to be solved in the utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

To a preferred embodiment shown in Figure 6, it comprises keycap 1, silica gel push-button 2, conductive film 3, substrate 4 and intersects mutually and rotating inside and outside

scissors pin

5,6 as Fig. 1.Keycap 1 is installed on the silica gel push-button 2, and silica gel push-button 2 is installed on the substrate 4 by conductive film 3, inside and

outside scissors pin

5,6 places on the silica gel push-button 2, fixedlys connected with keycap 1 and substrate 4 respectively in interior scissors pin 5 two ends, and 6 on outer scissors pin flexibly connects with keycap 1 and substrate 4 respectively.

Concrete, the outside of interior scissors pin 5 is provided with jack shaft 51, and the inboard of outer scissors pin 6 is provided with corresponding interstitial hole 61, by this 51 with realize intersecting and mutual rotation of inside and

outside scissors pin

5,6 cooperating of axis hole 61; As shown in Figure 5 and Figure 6, interior scissors pin 5 is provided with an installing hole 54, and scissors pin 5 is sheathed on the described silica gel push-button 2 by described installing hole 54 in this, because silica gel push-button 2 has elastic force, so can support outer scissors pin 6 and interior scissors pin 5; Under non-working condition, as a kind of preferred version, inside and

outside scissors pin

5,6 is all spent the angle for 4 one-tenth 15 with described substrate; In addition, be provided with the precompressed of 0.1mm between silica gel push-button 2 and keycap 1 inwall.

Along with pressing of keycap 1, all to the rotation of substrate 4 directions, silica gel push-button 2 is also to pressing down, by the circuit on the conductive film 3 conducting substrates 4 for inside and outside scissors pin 5,6.Compared with prior art, the distance in this press-key structure between inside and

outside scissors pin

5,6 and keycap 1 and the substrate 4 is shorter, and is therefore thin than existing keyboard, and good hand touch, and noise is low in the button process.In addition, this structure Design has also taken into full account manufacturing process, also has easy assembling, easily carries out advantages such as industrialization.

Please be equipped with movably

grab

11,41 on keycap 1 and the substrate 4 simultaneously referring to Fig. 4, described outer scissors pin 6 is connected with movably

grab

11,41 on the substrate 4 with this keycap 1 respectively.Like this, when keycap 1 pressed down, as shown in Figure 2, outer scissors pin 6 can be followed moving of

grab

11,41 and is affixed on the surface of substrate 4.Concrete, referring to Fig. 1, be provided with two pairs of

grabs

41,42 on the substrate 4 altogether, wherein a pair of for being used to connect the movably grab 41 of outer scissors pin 6, another is to then for being used to connect the fixedly grab 42 of interior scissors pin 5; Also be provided with two pairs of

grabs

11,12 on the keycap 1, wherein a pair of for being used to connect the movably grab 11 of outer scissors pin 6, another is to then for being used to connect the fixedly grab 12 of interior scissors pin 5; Be equipped with

axle

52,62 at the two ends of inside and outside

scissors pin

5,6, this inside and outside

scissors pin

5,6 all is connected with corresponding grab on substrate 4 and the keycap 1 by

axle

52,62.

During concrete enforcement, earlier conductive film 3 is lain on the substrate 4, silica gel push-button 2 is placed on this conductive film 3 then, axle 52 on the interior scissors pin 5 is loaded in the grab 42 of substrate 4, again the axle 62 on the outer scissors pin 6 is loaded in substrate 4 grabs, cooperates the axle 52 in the grab on the keycap 1 12 is aimed on the scissors pin 5 to interior scissors pin 5 jack shafts 51 toward pressing down outer scissors pin 6 interstitial holes 61, grab 11 on the keycap 1 is the axle 62 on the outer scissors pin 6 of aligning then, till pressing keycap 1 and sticking into.In addition, can also set up a polyester substrate 7 on substrate 4, silica gel push-button 2 is installed on this polyester substrate again, preferred, this polyester substrate can be selected the PET thin slice for use, and thickness can be 0.1mm.

In order to solve the problem of the keycap 1 rolling key that exists in the prior art, as the further improvement of aforementioned techniques scheme, a location hole 43 can also be set on substrate 4, corresponding, in described, be provided with the projection 53 that is complementary on the scissors pin 5.Like this, when keycap 1 is normally opened, break away and rolling key problem with regard to not occurring, and press in the process of motion, can also play guide effect at keycap 1.Concrete, as shown in Figure 3, aforesaid location hole 43 is a square hole, corresponding, the projection 53 on the interior scissors pin 5 also is the square projection, can prevent better that like this keycap 1 from breakking away and the rolling key.

After above-mentioned keyboard of notebook computer press-key structure assembling was finished, referring to shown in Figure 1, conductive film 3, substrate 4 were formed a not kinetoplast, and keycap 1, outer scissors pin 6, interior scissors pin 5, silica gel push-button 2 are formed a movable body.During work, face down from keycap 1 and to press, silica gel push-button 2 stressed bendings, the axle on the outer scissors pin 6 is with respect to the grab on the keycap 1, and the axle on the outer scissors pin 6 slides with respect to the grab on the substrate 4; And interior scissors pin 5 relative substrates 4 and keycap 1 can not slide, so keycap 1 is when being displaced downwardly to 4 one-tenth 0 ° of angles of substrate (with reference to figure 2), the direction skew that keycap 1 stretches inside scissors pin 5, the raised points on the silica gel push-button 2 will be depressed into the contact on the conductive film 3, circuit turn-on.
