Description

A kind of keyboard

The utility model relates to a kind of keyboard, and it mainly is applicable to computor-keyboard.

At present, be used for button on the computor-keyboard be provided with in regular turn as shown in Figure 1 keycap 1 ', flexible member 2 ', plastic cement plate 3 ', film 4 ' and base plate 5 '.Wherein, two pairs of keycaps 1 ' be provided be the guide rail 11 that the diagonal angle distributes ', 12 ', and in pair of guide rails 11 wherein ' the outside be provided with block 13 ', and the two pairs of guide rails 11 ', 12 ' central authorities be provided with cross column 14 ', this column 14 ' the top establish a cylindrical projections 15 '; Flexible member 2 ' to should projection 15 ' be provided with groove 21 '; Plate 3 in the plastic cement ' the be provided with hollow bead 30 of cross ', this hollow bead 30 ' Inner be provided with can set guide rail 11 ', 12 ' two pairs of guide-track grooves 31 ', 32 ', and in pair of guide rails groove 31 wherein ' on be provided with the breach 33 of a pair of limit stop 13 ' slippage ', and hollow bead 30 ' Inner also establish a locating ring 34 '.

But said structure cooperates the guide rail 12 of keycap 1 ' then ' increase gradually along the contact area of the two in the sliding process of guide-track groove 32 ' downwards pushed shown in Figure 2 in use, and its frictional resistance also increases, and the sensation of bite appears in guide rail easy to wear, and its keycap sense of touch is relatively poor; In addition, owing to be equipped with a plurality of buttons on the general computor-keyboard, when actual assembled, must be earlier with each flexible member 2 ' respectively by on insert the locating ring 34 of bead 30 ' Inner ' locate, and then with keycap 1 ' be pressed into plate 3 ' Inner in the plastic cement, then the installed flexible member 2 of keycap 1 ' be subject to ' influence produce and float, to follow-up keycap 1 ' press quality exert an influence, and if to change flexible member 2 ' need earlier dial-out keycap 1 ', so fragile keycap 1 ', this assembling mode is convenient inadequately as can be known, and efficient is low and cause the too high shortcoming of assembly cost.

Main purpose of the present utility model will provide a kind of keycap resistance of taxing little exactly, not the keyboard of bite.

Secondary objective of the present utility model is that a kind of keyboard easy to assembly will be provided.

For reaching above-mentioned purpose, the utility model is taked following technical scheme:

A kind of keyboard, mainly form by plate, flexible member, film and base plate in the keycap that is provided with in regular turn, the plastic cement, wherein keycap is provided with two pairs of guide rails, the central authorities of two pairs of guide rails are provided with column, and are provided with block in pair of guide rails wherein, and plate is provided with the bead of hollow in the plastic cement, two pairs of guide-track grooves of moulding in the bead, wherein the corresponding aforementioned block of pair of guide rails groove is provided with breach, and simultaneously, another cell wall to guide-track groove is made as step surface.

In addition, described flexible member can be set as integrated full slice system structure, and is provided with positioning convex column in this chip flexible member.

After adopting said structure, because the binding face of guide-track groove of the present utility model and guide rail is set as stair-stepping step surface, the contact-making surface of the two diminishes when making guide rail along the downward slippage of guide-track groove, and suffered wearing resistance also diminishes when sliding, thereby not having the sensation of bite, the sense of touch of keyboard is good during use.

In addition, the utility model assembling the time be earlier with keycap to being arranged in the plastic cement plate, again flexible member is packed into the below of plate from plastic cement, thereby flexible member is positioned in the projection of keycap and the plastic cement between plate, not only be convenient to assemble but also reduced the fraction defective of product.In addition, also original flexible member can be connected with into the whole piece formula, install simultaneously to reduce man-hour, to raise the efficiency thereby reach.

Below in conjunction with accompanying drawing and specific embodiment the utility model is done further detailed description.

Fig. 2 is a cross-sectional schematic of commonly using product;

Fig. 3 is a three-dimensional exploded view of the present utility model;

Fig. 4 is an elevational schematic view of the present utility model;

Fig. 5 be among Fig. 4 A-A to cutaway view;

Fig. 6 be among Fig. 4 B-B to cutaway view.

Shown in Fig. 3-6, keyboard described in the utility model mainly is made up of plate 2, flexible member 3, film 4 and base plate 5 in the keycap 1 that is provided with in regular turn, the plastic cement.Wherein:

Keycap 1 is provided with two pairs of guide rails 11,12 that square crossing is arranged, and a pair of block 13 is set in the outer ends of pair of guide rails 11 wherein, and the central authorities of two pairs of guide rails 11,12 are provided with cross column 14, a cylindrical projections 15 is established on the top of this column 14, and these projection 15 correspondences are embedded at groove 31 Inner that are provided with on the flexible member of being made by silica gel 3; Plate 2 is provided with hollow cross bead 20 in the plastic cement, and this bead 20 Inner are provided with the two pairs of guide- track grooves 21,22 that can set guide rail 11,12, and the breach 23 of a pair of limit stop 13 positions is set on pair of guide rails groove 21 wherein.Design focal point of the present utility model is that another cell wall to guide-track groove 22 is set as stair-stepping step surface 221, and this step surface 221 can be set as smooth surface.

When adopting the said structure combination, can be earlier with after in the corresponding respectively guide- track groove 21,22 that is embedded at plate 2 in the plastic cement of two pairs of guide rails 11,12, again with the below of flexible member 3 plate 2 from plastic cement to being positioned at its bead 20 Inner, and make 31 pairs of grooves on its flexible member 3 be positioned at projection 15, so assembling not only makes things convenient for and has reduced the fraction defective of assembling, simultaneously follow-up keycap can not produce floating sense when printing, and can improve its press quality.

The utility model in use, push 1 guide rail of keycap along the downward slippage of guide-track groove, because the flute wall surfaces of guide-track groove 22 is set as step surface 221, the contact-making surface of guide rail and guide-track groove is diminished, it is big that the space becomes, thereby reduced the resistance that guide rail slides downwards, reduced guide rail impaired, button has good sense of touch when therefore using.

In addition, also can fuse and form whole piece formula structure being positioned at flexible member 3 under each keycap 1 aforementioned, and the locating convex block 32 of some is set on this chip flexible member 3, locating convex block 32 can be embedded in the plastic cement in 2 times integrated location holes 24 of plate, when production and assembly, will not be positioned at each keycap 1 time by every 3 pairs of flexible member like this, can install simultaneously, reduce man-hour, enhance productivity and locate firm.
