Description

Button structure

The invention relates to a button structure, in particular to a mechanical button structure.

Generally, the button structure generally provides a mechanism for the keycap to move up and down through the cross-connected bracket, and an elastic member (such as a silicone round protrusion) is disposed under the key cap to provide a keycap restoring force to drive the keycap back to the original position ( That is, the position when it is not pressed). The bracket and the elastic member are usually compactly arranged to reduce the required space for the button structure, but the bracket structure has a certain structural complexity because the brackets are cross-connected and the silicone rounds are disposed therebetween. In addition, the silicone dome needs to have a considerable structural volume to provide sufficient pressure for the user to feel the feedback (ie, the reaction force felt by the user when pressed), so that the volume required for the button structure has limitations. Therefore, such a button structure is difficult to apply to a thin keyboard unless the stability of the key cap actuation or the feedback feel is compromised or sacrificed.

In view of the problems in the prior art, one of the objects of the present invention is to provide a button structure that utilizes a slider mechanism to interact with a keycap to guide the keycap up and down and use a magnetic force as a restoring force and sliding of the keycap. It is simplified in structure and suitable for thin keyboards.

A key structure of the present invention comprises a base, a keycap, a sliding member, a guiding mechanism and a transmission mechanism. The base includes a bottom plate and a first magnetic portion. The keycap is disposed on the bottom plate. The sliding member is disposed between the bottom plate and the key cap and is movable parallel to the first direction with respect to the bottom plate, the sliding member includes a second magnetic portion disposed opposite to the first magnetic portion, the first magnetic portion A magnetic attraction is generated between the second magnetic portion. The guiding mechanism is disposed on the keycap and the bottom plate for guiding the keycap to be restricted to move parallel to the second direction with respect to the bottom plate. The transmission mechanism is disposed on the keycap and the sliding member for moving the sliding member parallel to the first direction and the key The caps are driven in parallel with each other in a movement in the second direction. Wherein, when the key cap receives a pressing action and moves toward the bottom plate in the second direction, the key cap drives the sliding member to move in the first direction through the transmission mechanism, so that the second magnetic portion is away from the first a magnetic portion; when the pressing action disappears, the magnetic force drives the second magnetic portion to approach the first magnetic portion, so that the sliding member moves in the opposite direction of the first direction and drives the keycap through the transmission mechanism The second direction moves in the opposite direction away from the bottom plate. Thereby, the key cap can move up and down relative to the base through the sliding member, the guiding mechanism and the transmission mechanism, and the magnetic attraction force acts as a restoring force of the key cap to return to the original position.

Another button structure of the present invention comprises a base, a keycap, two sliding members and two transmission mechanisms. The keycap is disposed on the bottom plate. The two sliding members are oppositely disposed between the bottom plate and the key cap and are movable relative to the bottom plate in a direction parallel to a first direction. Each of the sliding members includes a magnetic portion, and the two magnetic portions are oppositely disposed and generate a magnetic portion. suction. The two transmission mechanisms are correspondingly disposed on the keycap and the two sliding members for mutually moving the sliding member parallel to the first direction and the movement of the key bearing parallel to a second direction. When the key cap receives a pressing action and moves toward the bottom plate in the second direction, the key cap drives the two sliding members to move away from each other in parallel with the first direction through the two transmission mechanisms, so that the two magnetic portions are mutually Far away; when the pressing action disappears, the magnetic force drives the two magnetic portions to approach each other such that the two sliding members approach each other in parallel with the first direction and drive the keycap to the opposite of the second direction through the two transmission mechanisms The direction moves away from the bottom plate. Thereby, the key cap can move up and down relative to the base through the two sliding members and the two transmission mechanisms, and the magnetic attraction force acts as a restoring force of the key cap to return to the original position.

Compared with the prior art, the button structure of the present invention utilizes magnetic attraction force as the restoring force of the keycap, and can easily provide sufficient pressing feedback feel, so that it is not necessary to use the silicone round protrusion, and the operating space of the silicone rubber dome can be saved. The design of the sliding member and the transmission mechanism and the connection design are more flexible, which helps to improve the stability of the operation of the key cap. Therefore, the button structure of the present invention has the stability of the key cap actuation and sufficient pressing feedback feel, and effectively solves the dilemma faced by the current keyboard design in the prior art.

The button structure 1 includes a base 10, a keycap 12, a sliding member 14, a guiding mechanism 16, and a transmission mechanism 18. The keying cover 12 is disposed on the base 10. The sliding member 14 is slidably disposed on the base 10 and Between the keycaps 12, the guiding mechanism 16 is used to guide the keycap to move relative to the base 10. The transmission mechanism 18 is used to drive the sliding member and the movement of the keycap. Further, in the embodiment, the base 10 includes a bottom plate 102, a movable member 104, and a thin film circuit board 106. The bottom plate 102 is generally made of a metal material and is mainly used for structural support. The key cap 12 is disposed on the bottom plate 102. The movable member 104 is slidably disposed under the bottom plate 102, and the film is electrically The circuit board 106 is disposed on the bottom plate 102. The thin film circuit board 106 has a switching circuit (not shown) for triggering when the keycap 12 is pressed down, for example, outputting a signal, in response to pressing on the keycap 12. operating. In addition, the base 10 further includes a first magnetic portion 108 disposed on one of the protrusions 1042 of the movable member 104 such that the first magnetic portion 108 can move together with the movable member 104. The protruding portion 1042 passes through the openings 1022, 1062 of the bottom plate 102 and the thin film circuit board 106, and extends toward the keycap 12. The first magnetic portion 108 is located at the protruding portion 1042, whereby the first magnetic portion 108 can be driven by the movable member 104. The motion is not interfered with by the structure of the bottom plate 102 and the thin film circuit board 106. In addition, in the perspective of FIG. 3, the keycap 12 has two skirts 122 extending downward from the opposite edges of the keycap 12 (ie, toward the base 10), and the first magnetic portion 108 is located. Between the two skirts 122, the keycap 12 can shield the first magnetic portion 108, and maintain the overall beauty of the button structure 1.

The sliding member 14 is disposed between the bottom plate 102 and the keycap 12 and is movable parallel to the first direction D1 (indicated by a thick arrow) with respect to the bottom plate 102. The sliding member 14 and the movable member 104 are located on opposite sides of the bottom plate 102. (The slider 14 is above the bottom plate 102 and the movable member 104 is below the bottom plate 102). The slider 14 includes a second magnetic portion 142 (the hidden outline is shown by a dashed line) disposed opposite to the first magnetic portion 108 and also between the skirts 122. In practice, the main body of the slider 14 is a The plastic ejection plate member, the second magnetic portion 142 is a magnet embedded in the edge of the plastic injection plate member, but the invention is not limited thereto. A magnetic attraction force F1 (indicated by a double-lined arrow) is generated between the first magnetic portion 108 and the second magnetic portion 142 to drive the first magnetic portion 108 and the second magnetic portion 142 closer to each other. In practice, one of the first magnetic portion 108 and the second magnetic portion 142 is implemented by a magnet, and the other of the first magnetic portion 108 and the second magnetic portion 142 is implemented by a magnet of opposite polarity or other paramagnetic material.

The guiding mechanism 16 includes two guiding grooves 162 extending in a second direction D2 (indicated by thick arrows) and two guiding members 164 slidingly engaged with the guiding grooves 162 (in FIG. 2, the key cap is shown) 12 is shielded in a dotted line, wherein the two guiding grooves 162 are oppositely disposed on the bottom plate 14, and the two guiding members 164 are correspondingly disposed on the lower surface 12a of the keycap 12. In practice, the guide groove 162 is integrally formed with the bottom plate 14 (for example, the bottom plate 14 is a stamped piece of a paramagnetic plate, and the upper portion is bent to form a protruding portion 1042 (also as the first magnetic portion 108) and the guide groove 162 ( In a glyph outline) The guiding member 164 may be integrally formed with the key cap 12 (for example, plastic injection molding) or directly formed into a protruding structure from the edge of the keycap 12, but the invention is not limited thereto. Thereby, the guiding mechanism 16 can guide the keycap to move in a restricted direction parallel to the second direction D2 with respect to the bottom plate 102. In the embodiment, the guiding groove 162 has the function of guiding the guiding member 164 to move and restricting the moving range of the guiding member 164.

The transmission mechanism 18 includes two guiding grooves 182 extending in a third direction D3 (indicated by thick arrows) and two guiding members 184 slidingly engaged with the guiding grooves 182 (in FIG. 2, it is shielded by the keycap 12) The outline is shown by a dotted line). The two guiding slots 182 are oppositely disposed on the sliding member 14. The two guiding members 184 are correspondingly disposed on the lower surface 12a of the keycap 12 and also extend in the third direction D3. The third direction D3 is opposite to the first direction. In the present embodiment, the first direction D1 is perpendicular to the second direction D2, but the invention is not limited thereto. In addition, in practice, the guide groove 182 is integrally formed with the slider 14 (for example, the slider 14 is formed at the same time as the channel as the guide groove 182), and the guide member 184 is integrally formed with the key cap 12 (for example, plastic injection molding). ), but the invention is not limited thereto. Thereby, the transmission mechanism 18 can drive the movement of the slider 14 parallel to the first direction D1 (i.e., the horizontal movement) and the movement of the keycap 12 parallel to the second direction D2 (i.e., the vertical movement).

In this embodiment, the guiding mechanism 16 of the present embodiment adopts two sets of guiding (and limiting) structures (ie, one guiding slot 162 plus a corresponding guiding member 164 as a group), and is oppositely disposed on the key. The two sides of the cap 12 have a structurally symmetrical effect, and can provide stable up and down movement of the key cap 12. However, the present invention is not limited thereto, and for example, multiple sets or only one set of guiding structures can be utilized. The effect of the guiding mechanism. In addition, the transmission mechanism 18 of the embodiment also adopts two sets of guiding structures (ie, one guiding slot 182 plus a corresponding guiding member 184 as a group), and is oppositely disposed on both sides of the keycap 12, and has structural symmetry. The effect of the present invention is not limited thereto. For example, a plurality of sets, or only one set of guiding structures, can exert the effect of the transmission mechanism of the present invention. In addition, in the present embodiment, the guiding mechanism 16 and the transmission mechanism 18 are disposed in mutually perpendicular directions in a plan view of the button structure 1, and the keycap 12 is guided through the slot guides 164 and 184 on all four sides thereof. Leading (or structurally constrained), it can achieve a fairly reliable and stable up and down action. It is added that, in practice, the guiding groove 162 of the guiding mechanism 16 and the guiding member 164 can be oppositely disposed on the keycap 12 And the bottom plate 102. Similarly, the guiding groove 182 of the transmission mechanism 18 and the guiding member 184 can be oppositely disposed on the key cap 12 and the sliding member 14; in addition, the guiding structures of each group are not limited to the same setting (for example, the guiding mechanism) The two guide grooves 162 of the 16 are not necessarily disposed on the bottom plate 102, and the two guide grooves 182 of the transmission mechanism 18 need not be disposed on the sliding member 14).

Please also refer to FIG. 4 and FIG. 5 . FIG. 4 is a cross-sectional view of the button structure 1 along the line XX of FIG. 1 after pressing, and FIG. 5 is a cross-sectional view of the guiding mechanism 16 along the line YY of FIG. 1 . . When the keycap 12 receives a pressing action (for example, the user presses the keycap 12 with a finger) and moves toward the bottom plate 106 in the second direction D2 (ie, moves downward), the keycap 12 transmits through the transmission mechanism 18 (ie, the guide member) The 184 is further moved into the guide groove 182) to drive the slider 14 to move in the first direction D1, so that the second magnetic portion 142 is away from the first magnetic portion 108, as shown in FIG. 4; at this time, the key cap 12 can be defined as being pressed. position. After the keycap 12 is pressed, the magnetic attraction force F1 is weakened, but still enough to move the second magnetic portion 142 toward the first magnetic portion 108, so when the pressing action disappears (for example, the user's finger moves away from the keycap 12), the magnetic force The suction force F1 drives the second magnetic portion 142 to approach the first magnetic portion 108, so that the slider 14 moves in the opposite direction of the first direction D1 and transmits through the transmission mechanism 18 (ie, the guide member 184 is gradually separated from the guide groove 182) to drive the keycap 12 Moving away from the bottom plate 102 in the opposite direction of the second direction D2 (i.e., moving upward) until moving to the state as shown in Fig. 3; at this time, the keycap 12 can be defined to be in an unpressed position. During the entire pressing and releasing of the keycap 12, the keycap 12 can be stably moved parallel to the second direction D2 through the guiding mechanism 16, as shown in FIG. 5, wherein the guide of the keycap 12 is pressed by a broken line. The outline of the lead 164. The lower edge of the guiding member 164 protrudes into the U-shaped contour guiding groove 162, so that when the lower edge of the guiding member 164 is moved upward to the upper edge of the guiding groove 162 which is caught in the U-shaped contour, the keycap 12 is restrained. One of the viable design options for the highest position that can be reached.

Please also refer to FIG. 6. FIG. 6 is a cross-sectional view taken along line X-X of FIG. 1 when the button structure 1 is in a stored state. In the present embodiment, the movable member 104 is operatively movable in the first direction D1 to drive the slider 14 to move in the first direction D1 and to drive the keycap 12 to move toward the bottom plate 102 in the second direction D2 through the transmission mechanism 18 ( That is, moving downwards, so that the button structure 1 can be in the storage state, as shown in FIG. 6; at this time, the keycap 12 is substantially in the pressing position, but the present invention does not Limited. Further, the protruding portion 1042 passes through the bottom plate 102, and when the movable member 104 moves in the first direction D1, the protruding portion 1042 is also moved in the first direction D1, so that the movable member 104 drives the sliding member 14 with the protruding portion 1042. The first direction D1 moves. In the present embodiment, since the first magnetic portion 108 is located at the protruding portion 1042, when the movable member 104 is operable to move the first direction D1 to drive the slider 14 to move in the first direction, the first magnetic portion 108 contacts the second magnetic portion 142, which is advantageous for the movable member 104 to move stably together with the slider 14 and to maintain the button structure 1 in the stowed state. At this time, the height of the key cap 12 is lowered below the height of the keyboard main frame 13 (shown by a broken line in FIG. 1), (1) the overall thickness of the button structure 1 is thinned to facilitate the user to carry and carry, and (2) The protection of the keyboard frame 13 reduces the chance that the keycap 12 will be detached by an external force during the user's carrying process. Therefore, when the button structure 1 of the present invention is in use, it can provide a sufficient pressing stroke of the user (where the pressing feedback feel can be determined by designing the magnetic attraction force F1), and in the storage state, the overall thickness can be thinned and facilitated. The storage and the protection of the keyboard frame 13 reduce the chance that the keycap 12 is detached by an external force.

In addition, when the movable member 104 moves together with the slider 14, the first magnetic portion 108 is kept in contact with the second magnetic portion 142 (based on the magnetic attraction force F1), so that the user does not need to overcome the magnetic attraction force F1 to move and slide with less force. Item 14. It should be noted that, in this embodiment, the first magnetic portion 108 is located at the protruding portion 1042, so that the first magnetic portion 108 also moves when the movable member 104 moves, but the invention is not limited thereto. For example, the first magnetic portion 108 is disposed on other members of the base 10, for example, disposed on the bottom plate 102 (the second magnetic portion 142 is also disposed correspondingly). At this time, the movable member 104 directly pushes the body of the slider 14 with the protruding portion 1042, and The distance between the first magnetic portion 108 and the second magnetic portion 142 is gradually increased, and the slider 14 is still operable to drive the keycap 12 down to enable the button structure 1 to be in the stowed state. In addition, in the present embodiment, the guiding mechanism 16 can limit the highest position of the keycap 12, and the position of the first magnetic portion 108 also limits the stopping position of the second magnetic portion 142 toward the first magnetic portion 108 (ie, contact The position of the first magnetic portion 108) further limits the highest position of the keycap 12. Therefore, in practice, the highest position of the keycap 12 (corresponding to the aforementioned unpressed position) can be restricted by an alternative design. In this embodiment, when the keycap 12 is in the unpressed position (ie, when the pressing action is cancelled) When the time is lost, the first magnetic portion 108 contacts the second magnetic portion 142, and the guiding groove 162 also blocks the guiding member 164; however, the invention is not limited thereto.

In addition, in the embodiment, the sliding member 14 further has a limiting hole 144. The bottom plate 102 includes a positioning member 1024 extending through the opening 1064 of the film circuit board 106 and extending toward the keycap 12 and extending into the limit. Hole 144. The limiting aperture 144 limits the extent of relative movement of the positioning member 1024, that is, limits the extent of sliding of the slider 14 relative to the base 10 (ie, also indirectly limits the highest and lowest positions of the keycap 12). In addition, the matching of the limiting hole 144 and the positioning member 1024 also contributes to the assembly of the slider 14 to the base 10.

Please refer to FIG. 7 to FIG. 10, FIG. 7 is an exploded view of a button structure 3 according to another embodiment of the present invention, FIG. 8 is a cross-sectional view of the button structure 3 in an unpressed state, and FIG. 9 is a button. FIG. 10 is a cross-sectional view of the structure 3 after being pressed, and FIG. 10 is a cross-sectional view of the button structure 3 in a stored state. In the present embodiment, the button structure 3 and the button structure 1 have substantially the same structure. For convenience of explanation, the button structure 3 follows the component symbol of the button structure 1. For other descriptions of the button structure 3, the button structure 1 can be directly referred to. The description of the components will not be described again; the appearance of the button structure 3 can be directly referred to the first figure, and the position of the sections 8 to 10 is equivalent to the line XX in the first figure. The main difference between the button structure 3 and the button structure 1 is that the mechanism for moving the key cap 12 up and down is slightly different. In the present embodiment, the button structure 3 includes two sliders 34a, 34b and two transmission mechanisms 38a, 38b. The two sliding members 34a, 34b are oppositely disposed between the bottom plate 102 and the keycap 12 and are relatively movable parallel to the first direction D1 with respect to the bottom plate 102. Each of the sliding members 34a, 34b includes a magnetic portion 342a, 342b (hidden The outline is shown in dashed lines. The two magnetic portions 342a, 342b are oppositely disposed and generate a magnetic force F3 (indicated by thick double arrows). The two transmission mechanisms 38a, 38b are correspondingly disposed on the keycap 12 and the two sliding members 34a, 34b for moving the sliders 34a, 34b parallel to the first direction D1 and the keycap 12 parallel to the second direction D2. The movement is driven by each other. The guiding groove 382a of the transmission mechanism 38a is disposed on the sliding member 34a, the guiding member 384a of the transmission mechanism 38a is disposed on the keycap 12, the guiding groove 382b of the transmission mechanism 38b is disposed on the sliding member 34b, and the guiding member 384b of the transmission mechanism 38b Set on the keycap 12. When the keycap 12 accepts a pressing action (for example, the user presses the key with a finger When the cap 12) moves toward the bottom plate 102 in the second direction D2 (ie, moves downward), the key cap 12 drives the two sliding members 34a, 34b away from each other in parallel with the first direction D1 through the two transmission mechanisms 38a, 38b, so that The two magnetic portions 342a, 342b are also away from each other, as shown in Fig. 9; at this time, the keycap 12 can be defined at a pressing position. After the keycap 12 is pressed, the magnetic attraction force F3 is weakened, but the two magnetic portions 342a and 342b are still close to each other, so when the pressing action disappears (for example, the user's finger moves away from the keycap 12), the magnetic attraction force F3. Driving the two magnetic portions 342a, 342b to be close to each other (in the present embodiment, the two are close to each other), so that the two sliding members 34a, 34b are close to each other and pass through the two transmission mechanisms 38a in parallel with the first direction D1. 38b urges the keycap 12 to move away from the bottom plate 102 in the opposite direction of the second direction D2 (i.e., upwardly) until it moves back to the state shown in Figure 8; at this point the keycap 12 can be defined to be in an unpressed position. During the entire pressing and release of the keycap 12, the keycap 12 can be stably moved parallel to the second direction D2 through the guiding mechanism 16 (the guide groove 162 and the guide member 164). At the same time, when the button structure 3 of the present invention is in use, it can provide a sufficient pressing stroke of the user (wherein the pressing feedback feel can be determined by designing the magnetic attraction force F3, and the two magnetic portions 342a, 342b are separated instantaneously, and the magnetic attraction force F3 is instantaneous. Dramatically reduced, it acts like the feel of a conventional rubber bowl with a collapse of the rubber dome). Similarly, as shown in Fig. 10, when the button structure 3 is in the stowed state, the overall thickness can be made thinner for easy storage; and the protection of the keyboard main frame 13 reduces the chance of the keycap 12 being detached by an external force.

In the present embodiment, in the case of the transmission mechanisms 38a, 38b, the transmission mechanisms 38a, 38b are also designed to slidably engage the inclined guide grooves and the guide members, that is, the transmission mechanism 38a includes the third direction D3. a guiding groove 382a (disposed on the sliding member 34a) and a guiding member 384a (provided on the keycap 12) slidably engaged with the guiding groove 382a, and the transmission mechanism 38b includes a guiding groove 382b extending in the fourth direction D4 (disposed on the sliding member) 34b) and a guiding member 384b (provided in the keycap 12) slidably engaged with the guiding groove 382b, wherein the third direction D3 and the fourth direction D4 are inclined with respect to the first direction D1 and the second direction D2; wherein the guiding groove The moving inter-transmission mechanism formed by the interaction of the guiding members 384a, 384b with the guiding members 384a, 384b respectively is equivalent to the moving inter-transmission mechanism formed by the interaction between the guiding groove 182 and the guiding member 184, and therefore will not be described in detail. Other descriptions of the guide groove 382a and the guide 384a (example) For the position and quantity, refer to the descriptions of the foregoing guiding slot 182 and the guiding member 184, and details are not described herein. In addition, the third direction D3 is +45 degrees with respect to the second direction D2, and the fourth direction D4 is -45 degrees with respect to the second direction D2, so when the keycap 12 moves in the D2 direction, the two sliders 34a, The two magnetic portions 342a, 342b may be two magnets disposed opposite to each other, or one of the two magnetic portions 342a, 342b may be a magnet. The other one can be implemented for other paramagnetic materials. For the implementation of the sliders 34a, 34b and the magnetic portions 342a, 342b, reference may be made to the foregoing description of the slider 14 and the second magnetic portion 142, and no further details are provided.

In the embodiment, the button structure 3 can also have a design for lowering the keycap 12 into the storage state. The protruding portion 1042 of the movable member 104 directly functions as a rightward sliding slide 34b, and the movable member 104 is operable to be first. Moving in the opposite direction of the direction D1 to drive the two sliders 34a, 34b away from each other in parallel with the first direction D1, and then driving the keycap 12 to move downwardly toward the bottom plate 102 in the second direction D2 through the two transmission mechanisms 38a, 38b. . Further, the slider 34b has a hole 344 through which the protrusion 1042 passes through the opening 1022 of the bottom plate 102 and the opening 1062 of the film circuit board 106 and protrudes into the hole 344. When the button structure 3 is in the use state (ie, the user can press the input), the protruding portion 1042 and the hole 344 are relatively movable, so that the slider 34b can freely slide parallel to the first direction D1, without being protruded. 1042 interference. When the button structure 3 is to be in the storage state for storage, the user can still operate the movable member 104 to move the protruding portion 1042 to the right in the opposite direction of the first direction D1 to hook the hole 344 to pull the slider 34b to the right. .
