Description

Button and keyboard for applying the same

This creation is about a keyboard component, especially a button and a keyboard to which it is applied.

The keyboard is a very common input device, usually used with electronic devices, such as desktop computers, notebook computers, smart phones or tablets. However, for a long button (such as a blank button), it is easy to cause a poor power transmission due to the user pressing the edge or the corner portion of the button, resulting in a problem that the button cannot be lowered on average. Therefore, the configuration relationship of the interlocking structure to which the button is connected is an important factor affecting the function of the button.

As shown in FIG. 1 , in the top view of the conventional button structure, the conventional button structure P1 includes a key cap P2, two balance bars P3 and two scissors feet P4, wherein the two balance bars P3 are misaligned, that is, one of them. The side bar P31 of the balance bar P3 is closer to the edge of the keycap P2, and the side bar P32 of the other balance bar P3 is relatively farther from the edge of the keycap P2. However, the above-mentioned conventional button structure P1 still has the following problems in practical use:

First, since the two balance bars P3 are in a misaligned configuration, when the user presses the edge or the corner portion, the force cannot be instantaneously transmitted to the second balance bar P3, which causes a defect in the pressing function.

Second, since the side bar P31 of one of the balance bars P3 is closer to the edge of the keycap P2, the side bar P32 of the other balance bar P3 is relatively farther from the edge of the keycap P2. Therefore, the position where the two scissor feet P4 are disposed cannot be closer to the edge of the keycap P2, resulting in a limited support effect of the scissor foot P4 and easy to sway when pressed against the edge or corner of the keycap P2.

In view of the above problems, the present invention provides a button including a key cap, two balance bars, and at least one scissor connector. The key cap includes opposite two long sides, opposite two short sides, and an inner surface. Each balance bar member includes a main shaft rod and two side rods respectively connected to the two ends of the main shaft rod. The main shaft rod of the balance rod member is pivotally connected to the inner surface of the key cap and respectively located on two long sides, and two sides of each balance rod member The rods are connected to the bottom plate and respectively located on the two short sides, wherein the projections of the balance bars on the inner side of the two side bars of the same short side are substantially in the same straight line. The scissor connector is connected between the bottom plate and the key cap and located between the balance bar members, the two side bars of each balance bar member are respectively adjacent to the edges of the two short sides, and the scissors connector is adjacent to at least one short The edge of the side.

The scissor connector includes a first connecting member and a second connecting member, the first connecting member includes a first connecting arm and a first pivoting portion, and the second connecting member includes a second connecting arm and a second pivoting portion. The first pivoting portion and the second pivoting portion are mutually pivoted, and one side of at least one of the first connecting arm or the second connecting arm is further provided with a thickening portion, and the thickening portion is disposed corresponding to the short side. That is, the first connecting arm of the first connecting member or the second connecting arm of the second connecting member is adjacent to the short side of the keycap such that the thickened portion is relatively adjacent to the edge of the short side of the keycap.

Therefore, the projection of the two balance bars on the inner surface of the two sides of the same balance side is substantially a technical feature on the same straight line, so that the two side bars on the same side of the two balance bars do not have to be used again. Knowing the way of technical misalignment, the distance between the side bars of the two balance bars and the short edge of the keycap can be minimized, so that the positions of the scissors connectors can be closer to the edge of the short side of the keycap. The two side bars of each balance bar and the plurality of scissor connectors are adjacent to the edges of the short sides, thereby effectively preventing the problem of pressing the corners or edges of the keycaps.

In addition, since the projection of the two balance bars on the inner surface of the two sides of the same short side is substantially on the same straight line, the structural rigidity and the interlocking property of the two balance bars can be increased, so as to press the edge or the edge of the keycap. At the corners, the power transmission can be faster and smoother.

Furthermore, by increasing the thickness of the first connecting arm or the second connecting arm by the provision of the thickening portion, the structural strength of the scissor-type connector can be further increased, and the force transmission effect of pressing against the corner or edge of the keycap can be enhanced.

In one embodiment, the button may include a plurality of scissor connectors that are adjacent to the edges of the two short sides, respectively.

In an embodiment, the thickening portion may cover the first pivoting portion and the second pivoting portion. That is to say, the first connecting arm or the second connecting arm is thickened to extend to the side of the pivoting portion of the first connecting member and the second connecting member, thereby effectively strengthening the strength of the pivoting.

In an embodiment, the thickening portion is protruded from the first connecting arm or the two connecting arms toward the bottom plate, and the bottom plate corresponding to the thickening portion is provided with a through hole. Thereby, when the button is pressed down, the thickened portion can be positioned in the escape through hole without colliding with the bottom plate.

In an embodiment, the key cap may include a long center line, and the long center line is substantially parallel to the edges of the long sides, and the two balance bars are symmetrically disposed with a long center line.

The creation further provides a keyboard including a bottom plate and the above buttons. The button is vertically disposed on the bottom plate.

In this embodiment, the key cap 20 is disposed on the bottom plate 10 and has a rectangular cover shape. The key cap 20 includes two opposite long sides 21, two opposite short sides 22, and an inner surface 23. The inner surface 23 herein refers to the surface of the keycap 20 facing the bottom plate 10 (as shown in Fig. 4).

The balance bar members 30 are in the shape of a U-shaped rod body (which can be integrally formed by metal or plastic, for example, each balance bar member 30 can be formed by bending a pair of straight rods), and each balance bar member 30 is formed. The main shaft 31 and the two side rods 32 respectively connected to the two ends of the main shaft 31 are included. Here, the two side bars 32 are substantially perpendicular to the main shaft 31, and the main shafts 31 of the two balance bars 30 are pivotally connected to the inner surface 23 of the keycap 20 and respectively located on the two long sides 21 (as shown in FIG. 4). The main shaft 31 is pivotally connected to the sleeve inside the inner surface 23 of the keycap 20, and each of the main shafts 31 is substantially parallel to the edge of the long side 21, and the two side rods 32 of each balance rod 30 are connected to The bottom plates 10 are located on the two short sides 22, respectively.

As shown in FIG. 3, in this embodiment, the bottom plate 10 is provided with a connecting structure 12 corresponding to the position of the two side bars 32, and the ends of the two side bars 32 of each balance bar member 30 are further connected to an edge perpendicular to the short side 22. The end rod 33 is slidably assembled in the connecting structure 12 of the bottom plate 10. In other words, the end rod 33 can be slidably displaced along the connecting structure 12.

As shown in Fig. 5, a top view of the creation button, wherein the keycap 20 is presented in a perspective manner. In this embodiment, the projections of the two balance bars 30 on the same side of the two side bars 32 on the inner surface 23 of the keycap 20 (the inner surface 23 is shown in FIG. 4) are substantially in the same straight line (eg, Above the L1 line). In addition, in this embodiment, the keycap 20 includes a long centerline 24 that passes through the center of the keycap 20 and is substantially parallel to the edge of the long side 21 of each keycap 20, and two balance bars 30 is symmetrically arranged with a long centerline 24.

The at least one scissor connector 40 is connected between the bottom plate 10 and the keycap 20 and located between the two balance bar members 30. In this embodiment, at least one scissor connector 40 is two scissors. The connector 40 is not limited thereto, and the number of the scissors connector 40 can be adjusted according to actual needs. Specifically, if the length of the button 1 is short, a single scissors connector 40 can be disposed. The two side bars 32 and the two scissor connectors 40 of each balance bar 30 are respectively adjacent to the edges of the two short sides 22 of the keycap 20, that is, the two scissor connectors 40 and the balance bars 30 The position of the side bars 32 is adjacent the edge of the short side 22 of the keycap 20.

Therefore, the projection of the two side bars 32 on the same side of the second balance bar member 30 on the inner surface 23 is substantially a technical feature on the same straight line, so that the two balance bars 30 are on the same side of the two side bars 32. It is no longer necessary to dispose in a conventional manner as in the prior art, and the distance between the side bars 32 of the two balance bars 30 and the short side 22 of the keycap 20 can be minimized, thereby setting the positions of the scissor connectors 40. Closer to the edge of the short side 22 of the keycap 20, the two side bars 32 and the scissor connector 40 of each balance bar 30 are respectively adjacent to the edges of the two short sides 22, thereby effectively preventing the corner or edge function of the keycap 20 from being pressed. Bad problem.

In addition, since the projections of the two balance bars 30 on the inner surface 23 of the two side bars 22 are substantially in the same straight line, the structural rigidity and the interlocking property of the two balance bars 30 can be increased to achieve the pressing. When the key cap 20 is at the edge or corner, the force transmission can be faster and smoother.

As mentioned above, Figure 6 is a partial enlarged exploded view of the creation button. In this embodiment, the scissor connector 40 includes a first connecting member 41 and a second connecting member 42. The first connecting member 41 and the second connecting member 42 are respectively in a frame type, and the first connecting member 41 includes The first connecting arm 411 and the first pivoting portion 412 are adjacent to the edge of the short side 22 and the edge of the short side 22, wherein the first pivoting portion 412 is pivoted on the side of each of the first connecting arms 411. The second connecting member 42 also includes two second connecting arms 421 and a second pivoting portion 422 adjacent to the edge of the short side 22 and the edge of the short side 22 away from each other. The second pivoting portion 422 is a shaft hole disposed on one side of each of the second connecting arms 421 and corresponding to the first pivoting portion 412, and the first pivoting portion 412 and the second pivoting portion 422 are mutually pivoted. The first connecting member 41 is located in the second connecting member 42 and is pivotable relative to the second connecting member 42. It should be noted that if only a single scissor connector 40 is disposed on a single button, the two first connecting arms 411 and the second connecting arms 421 are respectively adjacent to the edges of the short sides 22 of the key caps 20 .

In addition, the projections of the first connecting arm 411 and the second connecting arm 421 on the inner surface 23 of the keycap 20 (the inner surface 23 is shown in FIG. 4) are substantially parallel to the short side 22 of the keycap 20. A side of at least one of the first connecting arm 411 or the second connecting arm 421 is further provided with a thickening portion 423 corresponding to the two short sides 22 . In this embodiment, the thickened portion 423 is protruded from the second connecting arm 421 and extends toward the bottom plate 10, and the thickened portion 423 is disposed corresponding to the two short sides 22, which means that the thickened portion 423 is at least disposed close to The first connecting arm 411 or the second connecting arm 421 of the edge of the short side 22 (here, disposed on the second connecting arm 421) further increases the structural strength of the scissor connector 40, and is reinforced and pressed against the keycap 20 The power transfer effect of the edge or corner of the short side 22. Therefore, in the arrangement of the single scissor connector 40, since the two first connecting arms 411 and the second connecting arms 421 are respectively adjacent to the short sides 22 of the keycaps 20, the thickening portion 423 can be The second connecting arm 411 or the second connecting arm 421 is disposed on the two first connecting arms 411 and the second connecting arms 421 at the same time.

Further, as shown in FIG. 7, the thickened portion 423 covers the first pivoting portion 412 or the second pivoting portion 422. That is, the range in which the first connecting arm 411 or the second connecting arm 421 is thickened includes at least the pivoting portion of the first connecting member 41 or the second connecting member 42 (that is, the first pivoting portion 412 and the second pivoting portion) In addition to the force transmission effect of the edge or corner of the short side 22 of the keycap 20, the strength of the pivotal connection of the scissors connector 40 can be effectively enhanced. In addition, the bottom plate 10 corresponding to the thickening portion 423 can be provided with a through hole 11 , and the bottom plate 10 is further provided with a thin film circuit board 13 , and the above-mentioned escape through hole 11 is penetrated through the thin film circuit board 13 . The escaping through hole 11 is for providing a space for accommodating the thickened portion 423 of the scissor-type connector 40 when the button 1 is pressed, and avoids the stroke of the thickening portion 423 from affecting the pressing of the button 1.

Thereby, as shown in FIG. 8, when the keycap 20 is lowered by the user's pressing, since the scissors connector 40 is further increased in thickness by the thickening portion 423 to strengthen the structural strength, the keycap 20 can be lowered. The middle portion is more stable, and the thickening portion 423 can be located in the escape through hole 11 of the bottom plate 10 without being hit by the bottom plate 10 after the key cap 20 is pressed down. The thinning of the button 1 is facilitated and the structural strength of the button 1 and the stability of the pressing process are further enhanced.
