Description

Press key component

Technical field

The utility model relates to a kind of press key component, particularly relates to a kind of balancing pole that prevents and comes off in the press key component of base plate.

Background technology

In general, in present press key component, can be average in order to make the action of keycap when being pressed, so a balancing pole is set between its base plate and keycap.

Consult Figure 1A and Figure 1B, a known press key component 1 mainly includes a keyboard board 11, a keycap 12 and a balancing pole 13.At this, the elements such as scissor bindiny mechanism, elastic component and thin film circuit assembly in the press key component 1 all omit and do not show.Keyboard board 11 is provided with a plurality of articulated section 11a, and keycap 12 is provided with a plurality of junction surface 12a.Balancing pole 13 has the shape of a ㄇ font haply, and balancing pole 13 has a body 13a and two free end 13b.Body 13a is bonded among the junction surface 12a of keycap 12 in the mode of rotating, and two free end 13b then are the articulated section 11a that is articulated in keyboard board 11 respectively.As mentioned above, when keycap 12 is pressed, the body 13a of balancing pole 13 will move along with keycap 12, and two free end 13b of balancing pole 13 then will rotate in the 11a of articulated section.

Yet when keycap 12 needed be pulled out or breaks away from keyboard board 11 because of factors such as collisions, balancing pole 13 often also can break away from keyboard board 11 (articulated section 11a) along with keycap 12.At this, because balancing pole 13 needs to be installed on keycap 12 and the keyboard board 11 with ad hoc fashion, therefore again balancing pole 13 is installed on keycap 12 and the keyboard board 11, this will cause sizable inconvenience.

Novel content

This is novel to adopt as detailed below feature so that solve the above problems basically.That is to say that this novel base plate that comprises has one first articulated section and one second articulated section, wherein, first articulated section is with respect to second articulated section; One keycap is arranged on the base plate, and has at least one junction surface; An and balancing pole, be connected between base plate and the keycap, and have one first body, two second bodies and two kinks, wherein, first body is bonded among the junction surface of keycap in the mode of rotating, and second body connects first body, and toward each other, kink connects second body respectively, and is articulated in first articulated section and second articulated section of base plate respectively.

Simultaneously, according to this novel press key component, first articulated section has one first pivoted hole, and second articulated section has one second pivoted hole, and kink is arranged among first pivoted hole and second pivoted hole in the mode of rotating respectively.

Again this novel in, the axis coinciding of the axle center of first pivoted hole and second pivoted hole.

In this was novel, the axle center of first pivoted hole was vertical with the axle center of second pivoted hole again.

In this was novel, first articulated section protruded on the base plate again, and had one haply for L shaped shape.

In this was novel, second articulated section protruded on the base plate again, and had one haply for L shaped shape.

For making this novel above-mentioned purpose, feature and advantage can more obvious easy to understand, elaborate especially exemplified by preferred embodiment and conjunction with figs. below.

Embodiment

Existing this novel preferred embodiment of conjunction with figs. explanation.

First embodiment

Consult Fig. 2 A and Fig. 2 B, the press key component 100 of present embodiment mainly includes a base plate 110, a keycap 120 and a balancing pole 130.

Base plate 110 has one first articulated section 111 and one second articulated section 112.First articulated section 111 and second articulated section 112 all are to protrude on the base plate 110, and first articulated section 111 is with respect to second articulated section 112.In addition, first articulated section 111 has one first pivoted hole 111a, and second articulated section 112 has one second pivoted hole 112a.In the present embodiment, the axis coinciding of the axle center of the first pivoted hole 111a and the second pivoted hole 112a is shown in the line A among Fig. 2 B.

Keycap 120 is arranged on the base plate 110, and has a plurality of junction surfaces 121.

Balancing pole 130 is connected between base plate 110 and the keycap 120, and balancing pole 130 has one first body 131, two second bodies 132 and two kinks 133.First body 131 is bonded among the junction surface 121 of keycap 120 in the mode of rotating.Two second bodies 132 connect first body 131, and two second bodies 132 are toward each other.Two kinks 133 connect two second bodies 132 respectively, and two kinks 133 are articulated in first articulated section 111 and second articulated section 112 of base plate 110 respectively.In more detail, two kinks 133 are arranged among the second pivoted hole 112a of the first pivoted hole 111a of first articulated section 111 and second articulated section 112 in the mode of rotating respectively.

As mentioned above, because the structure of two kinks 133 of balancing pole 130 and two kinks 133 are respectively and the connected mode of 112 of first articulated section 111 and second articulated sections, even when keycap 120 needs be pulled out or breaks away from base plate 110 because of factors such as collisions, balancing pole 130 can not break away from base plate 110 (or first articulated section 111 and second articulated section 112) along with keycap 120 yet, thereby can save the inconvenience that again balancing pole 130 is installed on keycap 120 and the base plate 110.

Second embodiment

In the present embodiment, all indicate with identical Reference numeral with the first embodiment components identical.

Consult Fig. 3 A and Fig. 3 B, the press key component 100 ' of present embodiment mainly includes a base plate 110 ', a keycap 120 and a balancing pole 130.Base plate 110 ' has one first articulated section 111 ' and one second articulated section 112.

The difference of the present embodiment and the first embodiment maximum is, first articulated section 111 ' of press key component 100 ' and the set-up mode of second articulated section 112 are different from first articulated section 111 of press key component 100 and the set-up mode of second articulated section 112, and the structure of first articulated section 111 ' is different from the structure of first articulated section 111.

Shown in Fig. 3 B, first articulated section 111 ' has one first pivoted hole, 111 ' a, and second articulated section 112 has one second pivoted hole 112a.Specifically, the axle center (shown in line B) of first pivoted hole, 111 ' a is vertical with the axle center (shown in line C) of the second pivoted hole 112a.In addition, as shown in Figure 3A, first articulated section 111 ' has one and is L shaped shape haply.

Other component construction or feature as for present embodiment are all identical with first embodiment, can more clear easy to understand for the description that makes this case, omit the explanation of its repetition at this.

Similarly, because the structure of two kinks 133 of balancing pole 130 and two kinks 133 are respectively and the connected mode of 112 of first articulated section 111 ' and second articulated sections, even when keycap 120 needs be pulled out or breaks away from base plate 110 ' because of factors such as collisions, balancing pole 130 can not break away from base plate 110 ' (or first articulated section 111 ' and second articulated section 112) along with keycap 120 yet, thereby can save the inconvenience that again balancing pole 130 is installed on keycap 120 and the base plate 110 '.

Though this is novel with the preferred embodiment announcement, it is not novel in order to limit this, and any those skilled in the art not breaking away from this novel spirit and scope, can make various changes and retouching.Therefore this novel protection range is defined with accompanying Claim.
