Detailed Description
Please refer to fig. 1 to 3. The keyboard 1 according to the first embodiment of the present invention is suitable for a notebook computer (the outline of which is shown in fig. 1 by a dotted line). The keyboard 1 comprises a base 10, a plurality of key caps disposed above the base 10, a plurality of lifting mechanisms connected between the base 10 and the plurality of key caps, a flexible circuit board 16 (shown as a solid plate structure in fig. 3 for simplifying the drawing) disposed below the plurality of key caps, a plurality of elastic reset members disposed between the plurality of key caps and the base 10, and an upper cover 20 disposed above the base 10. The plurality of key caps includes a plurality of first key caps 122 arranged in a first region 12a (shown in phantom) and a plurality of second key caps 124 positioned in a second region 12b (shown in phantom). Each of the key caps corresponds to one of the lifting mechanisms, for example, the first key cap 122 corresponds to the first lifting mechanism 142, the second key cap 124 corresponds to the second lifting mechanism 144, the first lifting mechanism 142 is connected between the corresponding first key cap 122 and the base 10, and the second lifting mechanism 144 is connected between the corresponding second key cap 124 and the base 10. The key cap is movable up and down in a vertical direction Dv (shown by double headed arrows) relative to the base 10 via corresponding lifting mechanisms. The lifting mechanism can be made of a scissor bracket, a butterfly bracket or other mechanisms capable of providing up-and-down movement of the corresponding key caps; in practice, the lifting mechanism of the key cap with longer length (such as space bar, input key, backspace key, shift key, etc.) can be made of multiple scissor supports, butterfly supports or a combination thereof. The flexible circuit board 16 has a plurality of circuit switches (for simplicity of illustration, the arrangement positions are shown by circles with diagonal lines), each corresponding to one of the key caps, for example, a first key cap 122 corresponding to the first circuit switch 16a, a second key cap 124 corresponding to the second circuit switch 16b, the first key cap 122 being located above the first circuit switch 16a, and the second key cap 124 being located above the second circuit switch 16 b; in actual operation, the key cap with longer length can correspond to a plurality of circuit switches. Each elastic restoring member corresponds to a key cap, for example, the first elastic restoring member 182 corresponds to the first key cap 122, and the second elastic restoring member 184 corresponds to the second key cap 124; in actual operation, the key cap with a longer length can correspond to a plurality of elastic resetting pieces. The resilient return member may be formed, for example and without limitation, of a rubber dome that is compressed to resiliently deform (e.g., by a corresponding key cap that moves downward) and the resulting spring force may urge the corresponding key cap upward and back into place. In the first embodiment, the first elastic reset element 182 corresponds to the first circuit switch 16a, and the second elastic reset element 184 corresponds to the second circuit switch 16b, so that the first keycap 122 can press the first elastic reset element 182 to trigger the first circuit switch 16a, and the second keycap 124 can press the second elastic reset element 184 to trigger the second circuit switch 16b. The upper cover 20 has a plurality of openings, wherein the opening corresponding to the first key cap 122 is a first opening 20a, and the opening corresponding to the second key cap 124 is a second opening 20b, and the plurality of key caps (the first key cap 122 and the second key cap 124) are exposed through the plurality of openings, for example, the first key cap 122 is exposed through the first opening 20a and the second key cap 124 is exposed through the second opening 20 b.
Please refer to fig. 4 to fig. 6. In the first embodiment, the base 10 has a first plane 10a and a second plane 10b, and the first plane 10a and the second plane 10b are parallel to each other and are offset from each other in a vertical direction Dv. The first plane 10a corresponds to the first region 12a and the second plane 10b corresponds to the second region 12b. The flexible circuit board 16 is disposed on the base 10 in the vertical direction Dv, and includes a first board 162, a second board 164, and a plurality of connection portions 166 connecting the first board 162 and the second board 164, the first board 162 is disposed on the first plane 10a, the second board 164 is disposed on the second plane 10b, and the connection portions 166 are located between the first plane 10a and the second plane 10b. The flexible circuit board 16 can be simultaneously placed on the first plane 10a and the second plane 10b having different heights by the connection portion 166. Also, the connecting portion 166 extends along an extended path 166a (shown in fig. 6 in a dashed line), the extended path 166a including a C-shaped path segment (or so-called inverted C-shaped path segment from the perspective of fig. 6), such that the connecting portion 166 provides structural flexibility; on the other hand, the connecting portion 166 can provide structural buffering to facilitate the first plate 162 and the second plate 164 being offset in the vertical direction Dv. The structural arrangement can effectively inhibit or eliminate the force of pulling the first plate 162 from each other after the first plate 162 is placed on the first plane 10a and the second plate 164 is placed on the second plane 10b, so that the first plate 162 can be effectively flatly attached to the first plane 10a and the second plate 164 can be effectively flatly attached to the second plane 10b.
In the first embodiment, the first plate 162 has a first edge 162a, the second plate 164 has a second edge 164a, and the first edge 162a and the second edge 164a extend in parallel along an extending direction De (indicated by double-headed arrows in the figure). The connecting portion 166 has a first end 1662 and a second end 1664, and the connecting portion 166 is connected to the first edge 162a at the first end 1662 and to the second edge 164a at the second end 1664, the first end 1662 and the second end 1664 being aligned in a horizontal direction Dh (shown by double-headed arrows) that is perpendicular to the extending direction De and the vertical direction Dv. From the perspective of fig. 6, the C-shaped path segment is located on the right side of the line connecting the first end 1662 and the second end 1664 in the horizontal direction Dh. The alignment of the first end 1662 and the second end 1664 in the horizontal direction Dh means that there is at least a partial overlap between the projection of the first end 1662 in the horizontal direction Dh and the projection of the second end 1664 in the horizontal direction Dh, and is not limited to the overlapping of the edge extension lines or the center line extension lines of the first end 1662 and the second end 1664 in the horizontal direction Dh. However, in practice, the first end 1662 and the second end 1664 are not limited to the above, and are offset in the horizontal direction Dh.
In addition, in the first embodiment, the first edge 162a has a first recess 162b, and the first end 1662 is located in the first recess 162 b. The second rim 164a has a second recess 164b with a second end 1664 positioned within the second recess 164 b. The first recess 162b and the second recess 164b facilitate the first plate portion 162 and the second plate portion 164 to be disposed close to each other in the horizontal direction Dh. Also, in the first embodiment, the first recess 162b and the second recess 164b substantially cooperate to house the connecting portion 166.
In addition, in the first embodiment, a first connecting edge 166b and a second connecting edge 166c (the positions of which are shown in fig. 6 by dashed lines and are located at the first end 1662 and the second end 1664, respectively) may be defined on the connecting portion 166, and the connecting portion 166 is connected to the first plate portion 162 by the first connecting edge 166b and connected to the second plate portion 164 by the second connecting edge 166 c. In the first embodiment, the first connecting edge 166b is aligned with and connected to the first structural edge 162c of the first plate portion 162 (or the first edge portion 162 a), the second connecting edge 166c is aligned with and connected to the second structural edge 164c of the second plate portion 164 (or the second edge portion 164 a), and the first connecting edge 166b and the second connecting edge 166c are perpendicular to each other; however, the present invention is not limited thereto. The first structural edge 162c is a structural edge of the first recess 162b, and the second structural edge 164c is a structural edge of the second recess 164b, but the present invention is not limited thereto.
In addition, in the first embodiment, the first plate portion 162, the second plate portion 164 and the connection portion 166 are integrally formed from the same circuit board. For example, the flexible circuit board 16 is made of a thin film circuit board including an upper circuit carrier, a lower circuit carrier, and an intermediate insulating board disposed between the upper circuit carrier and the lower circuit carrier, and the circuit switch is made of contacts oppositely disposed on the upper circuit carrier and the lower circuit carrier. In practice, the flexible circuit board 16 may be implemented in other structures, such as a touch switch disposed on a flexible circuit board (Printed Circuit Board, FPC). For another example, a corresponding switch contact is formed on the FPC, and the elastic restoring member has a conductive portion so that the conductive portion can conduct the switch contact when the elastic restoring member is pressed downward. In the first embodiment, the first circuit switch 16a is formed on the first board portion 162, the second circuit switch 16b is formed on the second board portion 164, the flexible circuit board 16 further includes a conductive wire 16c (a portion of which is shown in dotted line) formed on the connecting portion 166, and the conductive wire 16c is connected to the second circuit switch 16b. In practice, the circuit on the second board 164 is connected to the circuit on the first board 162 via the circuit (including the conductive wire 16 c) on the connecting portion 166, and the flexible circuit board 16 is connected to the external communication (such as a notebook computer motherboard) via the circuit on the first board 162.
In the first embodiment, the base 10 forms the first avoidance groove 10c, the connecting portion 166 is movably located in the first avoidance groove 10c, so as to avoid the structural interference between the connecting portion 166 and the base 10, which also helps to enable the first plate 162 to be effectively flatly attached to the first plane 10a and the second plate 164 to be effectively flatly attached to the second plane 10b. In addition, in the first embodiment, the base 10 is a stepped plate having a through hole as the first avoiding groove 10c. The step plate comprises a first plate 102, a second plate 104 and a connecting plate 106 connecting the first plate 102 and the second plate 104, wherein a first avoiding groove 10c is formed at the joint of the first plate 102 and the connecting plate 106. The step plate may be implemented by stamping a metal plate, but is not limited thereto in practical operation. In addition, the first avoiding groove 10c is not limited to a through hole, for example, a groove is punched at the connection position of the first plate 102 and the connecting plate 106, and the connecting portion 166 is movably located in the groove, so as to replace the through hole and serve as the first avoiding groove 10c. In practice, the base 10 is not limited to a plate-like structure, and may be formed into a single structure or a combined structure having different height planes (for placing the first plate 162 and the second plate 164) by machining, injection molding, or the like.
Please refer to fig. 7. In the first embodiment, the upper cover 20 presses against the first plate 162 and the second plate 164 on the base 10 (the upper cover 20 presses against the first plate 162 on the first plane 10a of the base 10 and the upper cover 20 presses against the second plate 164 on the second plane 10b of the base 10). This structural arrangement helps to effectively flatten the first plate portion 162 against the first planar surface 10a and the second plate portion 164 against the second planar surface 10b. In addition, in the first embodiment, the second avoiding groove 202 (as shown in fig. 2) is formed at the position of the upper cover 20 corresponding to the connecting portion 166, so as to avoid the structural interference between the connecting portion 166 and the upper cover 20, which also helps to make the first plate 162 effectively flat against the first plane 10a and make the second plate 164 effectively flat against the second plane 10b.
In addition, in the first embodiment, the connecting portion 166 is provided with a C-shaped bending portion for structural flexibility, but the implementation is not limited thereto. For example, as shown in the second embodiment of fig. 8, the connecting portion 166' provides structural flexibility in an S-shaped bend, and the extension path 166a ' of the connecting portion 166' is S-shaped. Logically, on the other hand, the S-bend comprises two C-bends and the extension path 166a' comprises two C-path segments. For another example, as shown in the third embodiment of fig. 9, the connecting portion 166 "also provides structural flexibility with an S-shaped bend (i.e., the extending path 166a" is also S-shaped), and both ends of the S-shaped bend are aligned in the horizontal direction Dh. In practical operation, the connecting portion 166 may be replaced by other curved structures (e.g. W-shaped, spiral-shaped, a combination of curved structures, etc.), which is not described herein. In addition, in the first embodiment, the flexible circuit board 16 accommodates the connecting portion 166 by using the first recess 162b and the second recess 164b, so that the first board 162 and the second board 164 can be disposed close to each other in the horizontal direction Dh; however, the present invention is not limited thereto. For example, as shown in the fourth embodiment of fig. 10, neither the first plate 162 'nor the second plate 164' has a notch structure, and the first plate 162 'and the second plate 164' have a larger interval in the horizontal direction Dh, so that the connection portion 166 is disposed.
In addition, in the first embodiment, the first plate 162, the second plate 164 and the connecting portion 166 are formed by removing material (cutting away the partial area), so that a gap is formed between the connecting portion 166 and the first plate 162 and the second plate 164, but the present invention is not limited thereto. For example, as shown in the fifth embodiment of fig. 11, the connection portion 176 of the flexible circuit board 17 (connecting the first plate portion 172 and the second plate portion 174) is formed in a manner that is not removed (e.g., simply tearing the flexible circuit board 17), and this configuration helps to improve the utilization of the flexible circuit board and reduce the material cost.
In addition, in the first embodiment, the top surface of the first key cap 122 and the top surface of the second key cap 124 are substantially coplanar, the top surface of the first key cap 124 is smaller, the pressing stroke is also shorter, and the key cap can be used as a functional key cap, but the present invention is not limited thereto. For example, the second key cap 124 protrudes in the vertical direction Dv with respect to the first key cap 122. In addition, in actual operation, the difference in height between the first plane 10a and the second plane 10b in the vertical direction Dv may be generated for other reasons. For example, the second plane 10b is raised in order to match the structural dimensions of the second elevating mechanism 144. For another example, the base 10 is raised by the second plane 10b for the purpose of configuring other structural configurations (e.g., structural or component configurations within a notebook computer). For another example, to increase the recognition of the second key cap 124 to the user, the ease of pressing, the position of the key cap 124 is increased by increasing the second plane 10b.
In addition, in the first embodiment, the keyboard 1 is used as a keyboard of a notebook computer, but the present invention is not limited thereto. For example, the keyboard 1 may be adapted to other devices having a keyboard, such as an internal key keyboard on a device control panel, with appropriate structural modifications. For another example, the keyboard 1 may be modified by appropriate structure to form a stand-alone device, such as a desktop computer keyboard, wireless keyboard, numeric keyboard, etc.
In summary, the flexible circuit board of the present invention can make the first board portion and the second board portion of the flexible circuit board respectively located on the first plane and the second plane with different heights by the connection portion, so that the pulling force between the first board portion and the second board portion after being placed on the first plane and the second plane can be effectively suppressed or eliminated, and the first board portion can be effectively flatly attached to the first plane and the second board portion can be effectively flatly attached to the second plane. Therefore, part of the keys in the keyboard can be arranged at different heights, the action of the keys is not disturbed because the flexible circuit board is difficult to be simultaneously and adjacently arranged on the bottom plates at different heights, and the unstable touch and action of the circuit switch because the flexible circuit board is difficult to be simultaneously and adjacently arranged on the bottom plates at different heights is avoided.
The foregoing description is only of the preferred embodiments of the invention, and all changes and modifications that come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
