Abstract

A keyboard component comprises a bottom plate, a thin film circuit board assembly, a thin film plate and a balancing pole. The bottom plate has a standing out position and a first through hole. The standing out position is adjacent to and connected with the first through hole. The thin film circuit board assembly is mounted on the bottom plate and has a second through hole. The second through hold shall be correspondent to the first through hole and larger than the first through hole. The thin film circuit board assembly is separated from the standing out position on the bottom board by the second through hole. The thin film plate is mounted on the thin film circuit board assembly and has a third through hole. The third through hole is correspondent to the first through hole. One edge of the third through hole contacts the standing out position of the bottom plate. The balancing pole is connected with the bottom plate and mounted on the thin film plate. The balancing pole has a free end which contacts the edge of the third through hole and located on the standing out position in mode of swinging.

Description

The keyboard member

Technical field

This is novel to relate to a kind of keyboard member, particularly relates to a kind of keyboard member that noise is more reduced.

Background technology

Consult Fig. 1, Fig. 2 A and Fig. 2 B, a known keyboard member 1 mainly includes a base plate 11, a film circuit board assembly 12, a diaphragm 13 and at least one balancing pole 14.At this, elements such as scissor bindiny mechanism, elastic component and keycap in the keyboard member 1 all omit and do not demonstrate.

Base plate 11 has a plurality of protuberance 11a and a plurality of first through hole 11b, and each protuberance 11a is in abutting connection with each first through hole 11b.In addition, on each protuberance 11a, also be formed with one second through hole 11c (shown in Fig. 2 A and Fig. 2 B).Film circuit board assembly 12 is arranged on the base plate 11, and diaphragm 13 is arranged on the film circuit board assembly 12.In addition, have a third through-hole 12a and a fourth hole 13a respectively on film circuit board assembly 12 and diaphragm 13, third through-hole 12a overlaps with fourth hole 13a, and corresponding to the first through hole 11b of base plate 11.Specifically, the bore of third through-hole 12a and fourth hole 13a is all greater than the bore of the first through hole 11b.Therefore, film circuit board assembly 12 and diaphragm 13 are spaced apart with a specific range at the protuberance 11a of base plate 11.Balancing pole 14 is arranged between base plate 11 and the keycap (not shown), in more detail, balancing pole 14 has a body 14a and two free end 14b, and body 14a engages keycap in the mode of rotating, and two free end 14b are separately positioned among the second through hole 11c of protuberance 11a.

When keycap when base plate 11 is pushed downwards, the body 14a of balancing pole 14 will move down along with keycap, its free end 14b swing that then will make progress in the second through hole 11c of protuberance 11a.Then, when keycap is released out, (elastic restoring force that is provided because of the elastic component (not shown)) is provided the body 14a of keycap and balancing pole 14 immediately, the free end 14b of balancing pole 14 then in the second through hole 11c of protuberance 11a rapidly to lower swing.As mentioned above, the free end 14b of balancing pole 14 is rapid in the process of lower swing in the second through hole 11c of protuberance 11a, produce huge noise between free end 14b and the base plate 11 (or protuberance 11a) because of impact is excessive, thereby the comfortableness used of influence.

Therefore, this novel purpose provides a kind of keyboard member, and it can effectively eliminate the noise of balancing pole bump base plate.

Novel content

For solving the above problems this novel feature as detailed below that adopts basically.That is to say that this novel base plate that comprises has at least one protuberance and at least one first through hole, wherein, this protuberance is adjacent to first through hole; One film circuit board assembly is arranged on the base plate, and has at least one second through hole, and wherein, second through hole is corresponding to first through hole, and greater than first through hole, and the film circuit board assembly is by second through hole and spaced apart with the protuberance of base plate; One diaphragm is arranged on the film circuit board assembly, and has at least one third through-hole, and wherein, third through-hole is corresponding to first through hole, the protuberance of an edge butt base plate of third through-hole; And a balancing pole, be connected in base plate, and be arranged on the diaphragm, wherein, balancing pole has at least one free end, and free end is connected to the edge of third through-hole, and is arranged in the protuberance of base plate in the mode of swing.

Simultaneously, according to this novel keyboard member, protuberance has a fourth hole, and the free end of balancing pole is arranged in the fourth hole in the mode of swing.

In this was novel, diaphragm was made by rubber again.

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.

Consult Fig. 3, Fig. 4 A and Fig. 4 B, this novel keyboard member 100 mainly includes a base plate 110, a film circuit board assembly 120, a diaphragm 130 and a balancing pole 140.At this, elements such as scissor bindiny mechanism, elastic component and keycap in the keyboard member 100 all omit and do not demonstrate.

Base plate 110 has a plurality of protuberances 111 and a plurality of first through hole 112, and each protuberance 111 is all in abutting connection with each first through hole 112.In addition, on each protuberance 111, also has a fourth hole 111a (shown in Fig. 4 A and Fig. 4 B).

Film circuit board assembly 120 is arranged on the base plate 110, and has a plurality of second through holes 121.Each second through hole 121 is corresponding to each first through hole 112, and each second through hole 121 is greater than each first through hole 112.In addition, film circuit board assembly 120 is by second through hole 121 and spaced apart with the protuberance 111 of base plate 110.

Diaphragm 130 is arranged on the film circuit board assembly 120, and has a plurality of third through-holes 131.Each third through-hole 131 also is corresponding to each first through hole 112.Particularly, an edge 131a of each third through-hole 131 is connected to each protuberance 111 of base plate 110.In addition, diaphragm 130 can be made by rubber.

Balancing pole 140 is connected between base plate 110 and the keycap (not shown), and is arranged on the diaphragm 130.In more detail, balancing pole 140 has a body 141 and two free ends 142, body 141 engages keycap in the mode of rotating, each free end 142 is connected to the edge 131a of each third through-hole 131 of diaphragm 130, and each free end 142 is arranged among the fourth hole 111a of each protuberance 111 of base plate 110 in the mode of swing.

When keycap when base plate 110 is pushed downwards, the body 141 of balancing pole 140 is along with keycap moves down, its free end 142 is upwards swing in the fourth hole 111a of protuberance 111.Then, when keycap is released out, (elastic restoring force that is provided because of the elastic component (not shown)) will be provided the body 141 of keycap and balancing pole 140 immediately, and the free end 142 of balancing pole 140 will be rapidly to lower swing in the fourth hole 111a of protuberance 111.As mentioned above, because the edge 131a butt protuberance 111 of the third through-hole 131 of diaphragm 130, so among the fourth hole 111a of free end 142 at protuberance 111 of balancing pole 140 during rapidly to lower swing, the free end 142 of balancing pole 140 is touching diaphragm 130 (shown in Fig. 4 A) with pressure.That is to say that the buffering of the edge 131a by diaphragm 130 is kept out, the free end 142 of balancing pole 140 just can directly not strike base plate 110 or protuberance 111, thereby can avoid impact noise to produce.Therefore, can promote keyboard member 100 comfortableness in use.

Disclose with a preferred embodiment though basis is novel; but it is not novel in order to limit this, and any those skilled in the art is not in breaking away from these novel spirit and scope; can make various changes and retouching, therefore this novel protection range is defined with the accompanying Claim scope.
