Abstract

A roller input device includes a base plate, a support assembly, a roller seat, and a stop member. A click button switch and a first tilt button switch are provided on the top surface of the base plate. The support assembly is disposed on the base plate. The roller seat is disposed on the base plate and pivotally mounted on the support assembly. The roller seat can descend toward the base plate to a pressing position or tilt to a first tilt position. The stop member is connected to the roller seat and has a first stopping portion, with a first initial distance between the first stopping portion and the top surface of the base plate. When the roller seat is in the pressing position, the first initial distance is reduced to a first distance, and the first distance is less than the first pressing stroke of the first tilt button switch; when the roller seat is in the first tilt position, the first initial distance is reduced to a second distance, and the second distance is less than the click pressing stroke of the click button switch.

Description

Technical Field

[0001] This invention relates to an input device, and more particularly to a roller input device. Background Technology

[0002] Computers are often equipped with scroll wheel input devices, such as on the keyboard or mouse, to perform actions such as dragging, scrolling up and down pages, or switching menus.

[0003] To meet the more diverse needs of users, some special types of roller input devices offer other operating methods (such as allowing users to swing the roller) in addition to rotation and pressing operations to produce different functions.

[0004] However, since the roller can move in multiple different directions, if the angle or magnitude of the force applied by the user is slightly off, it is easy to cause erroneous operation. For example, if the user only intends to control the roller to swing, but accidentally applies too much force, the roller may fall down at the same time, resulting in an operational error. Summary of the Invention

[0005] In view of the above, in one embodiment, a roller input device is provided, including a base plate, a support assembly, a roller seat, and a stop member. The base plate has a top surface, and the top surface is provided with a click button switch and a first tilt button switch. The click button switch has a click pressing stroke, and the first tilt button switch has a first pressing stroke. The support assembly is disposed on the base plate and includes a first support and a second support, which are spaced apart from each other. The roller seat is disposed on the base plate and located between the first support and the second support. The roller seat includes a first end and a second end opposite to each other. The first end is pivotally mounted on the first support and the second end is pivotally mounted on the second support. The click button switch is adjacent to the first end, and the roller seat can selectively descend toward the base plate to a pressing position or tilt toward a first side to a first tilt position. The stop member is connected to the roller seat and has a first stop portion. The first stop portion and the first tilt button switch are located on one side of the roller seat, and there is a first initial distance between the first stop portion and the top surface of the base plate. When the roller seat is in the pressed position, pressing the roller seat triggers the click button switch, the first initial gap is reduced to the first gap, and the first gap is less than the first pressing stroke of the first tilt button switch; when the roller seat is in the first tilt position, pressing the roller seat triggers the first tilt button switch, the first initial gap is reduced to the second gap, and the second gap is less than the clicking pressing stroke of the click button switch.

[0006] In summary, according to the roller input device of the present invention, when the roller seat is in the pressing position and the click button switch is triggered, the distance between the first stop portion of the stop member and the top surface of the substrate is reduced and is less than the first pressing stroke of the first tilt button switch, so as to prevent the roller seat from tilting and accidentally touching the first tilt button switch; when the roller seat is in the first tilt position and the first tilt button switch is triggered, the distance between the first stop portion of the stop member and the top surface of the substrate is reduced and is less than the clicking pressing stroke of the click button switch, so as to prevent the roller seat from falling and accidentally touching the click button switch, thereby avoiding the situation where the user applies improper force and causes malfunction.

[0080] Various embodiments are described in detail below; however, these embodiments are merely illustrative and do not limit the scope of protection intended for this invention. Furthermore, some elements are omitted from the accompanying drawings in the embodiments to clearly illustrate the technical features of the invention. The same reference numerals will be used to denote the same or similar elements in all the drawings.

[0081] Figure 1 This is a schematic diagram illustrating an embodiment of the roller input device of the present invention. Figure 2 This is a schematic diagram illustrating another embodiment of the roller input device of the present invention. Figure 3 This is a perspective view of the first embodiment of the roller input device of the present invention. Figures 1 to 3 As shown, the scroll wheel input device 1 in this embodiment of the invention is a computer input device used to control the computer page to perform actions (such as dragging, scrolling up and down, or switching pages). In some embodiments, the scroll wheel input device 1 can be applied to the computer keyboard 2 (e.g., ...). Figure 1 (as shown), or, the scroll wheel input device 1 can also be applied to the computer mouse 3 (such as...). Figure 2 As shown), for example, the scroll wheel input device 1 can be installed inside the housing of the keyboard 2 or the mouse 3.

[0082] Figure 4 This is an exploded perspective view of the first embodiment of the roller input device of the present invention. Figure 5 This is a side view of a first embodiment of the roller input device of the present invention. Figures 3 to 5 As shown, the roller input device 1 includes a base plate 10, a support assembly 20, a roller seat 30, and a stop member 40, wherein the support assembly 20, the roller seat 30, and the stop member 40 are all disposed on the base plate 10.

[0083] like Figures 3 to 5 As shown, the substrate 10 has a top surface 101, on which a click button switch 15 and at least one tilt button switch are provided. In this embodiment, two tilt button switches (a first tilt button switch 11 and a second tilt button switch 12) are provided on the top surface 101 of the substrate 10. However, the number of tilt button switches can be set according to actual needs, and the present invention is not limited thereto.

[0084] Furthermore, the click button switch 15 has a click-press travel, the first tilt button switch 11 has a first press travel, and the second tilt button switch 12 has a second press travel. The click-press travel refers to the distance the click button switch 15 travels from its initial position to its trigger position. Similarly, the first press travel and the second press travel refer to the distances the first tilt button switch 11 and the second tilt button switch 12 travel from their initial positions to their trigger positions, respectively. For example, the click-press travel, the first press travel, and the second press travel can be 0.3mm, 0.4mm, or 0.5mm, respectively, but this is not a limitation.

[0085] In some embodiments, the substrate 10 may be a plate made of metal (e.g., iron, aluminum, or alloy) or plastic. Alternatively, the substrate 10 may also be a circuit board, such as a membrane, printed circuit board (PCB), flexible printed circuit board (FPCB), or rigid-flex PCB, etc.

[0086] like Figures 3 to 5 As shown, the support assembly 20 is disposed on the substrate 10 and includes a first support 21 and a second support 22, wherein the first support 21 and the second support 22 are spaced apart from each other. In this embodiment, the substrate 10 is fixed to the base 70, so that the substrate 10 can be further supported by the base 70. The first support 21 and the second support 22 are connected to the base 70. The substrate 10 has multiple holes, so that the first support 21 and the second support 22 can respectively pass through the multiple holes and be located on the substrate 10. In some embodiments, the support assembly 20 may also be directly fixed to the top surface 101 of the substrate 10, which is not a limitation.

[0087] like Figures 3 to 5 As shown, a roller seat 30 is disposed on a base plate 10 for assembling a roller 50, and the roller seat 30 is located between a first support 21 and a second support 22. In this embodiment, the roller seat 30 is a hollow shell with a groove 38, and the roller seat 30 has a pivot portion 37 (for example, the pivot portion 37 may be at least one shaft hole or pivot) for pivoting the roller 50. Here, a portion of the roller 50 (in this case, the lower half) is located in the groove 38, and the axis of the roller 50 is pivotally mounted on the pivot portion 37 of the roller seat 30, so that the roller 50 can rotate relative to the roller seat 30 when manipulated. Additionally, please refer to... Figure 1 and Figure 2 As shown, a portion of the scroll wheel 50 (in this case, the upper half) can be exposed outside the casing of the keyboard 2 or mouse 3 for user operation.

[0088] like Figures 3 to 5 As shown, the roller seat 30 includes a first end 31 and a second end 32 opposite to each other. The first end 31 is pivotally mounted on the first support 21, and the second end 32 is pivotally mounted on the second support 22. In this embodiment, the first support 21 has a guide groove 211, wherein the extending direction of the guide groove 211 is perpendicular to the substrate 10. The first end 31 of the roller seat 30 has a first pivot 311, which is pivotally mounted in the guide groove 211, so that in addition to being rotatable relative to the first support 21, the first pivot 311 can also be moved up and down along the guide groove 211. The second support 22 has a shaft hole 222, and the second end 32 of the roller seat 30 has a second pivot 321, which is pivotally mounted in the shaft hole 222, so that the second pivot 321 can be rotatable relative to the second support 22. In this way, the roller seat 30 can be selectively tilted or raised or lowered relative to the support assembly 20 via the first pivot 311 and the second pivot 321.

[0089] like Figures 3 to 5 As shown, the click button switch 15 is adjacent to and abuts against the first end 31 of the roller seat 30, so that the roller seat 30 can be held at a predetermined height position. The first tilt button switch 11 and the second tilt button switch 12 are respectively located on opposite sides of the roller seat 30. In this embodiment, the first tilt button switch 11 and the second tilt button switch 12 are both adjacent to the second end 32 of the roller seat 30. The user can operate the roller 50 and the roller seat 30 to perform actions such as lifting, lowering and tilting relative to the substrate 10, so that the roller seat 30 can selectively descend towards the substrate 10 to the pressing position to press the click button switch 15, or tilt towards the first side to the first tilt position to press and trigger the first tilt button switch 11, or tilt towards the opposite side to the first side to the second tilt position to press and trigger the second tilt button switch 12, thereby generating different signals and functions respectively.

[0090] like Figures 3 to 5 As shown, the stop member 40 can be a plate, block, or bracket connected to the roller seat 30. The stop member 40 can be integrally connected to the roller seat 30 or detachably assembled to the roller seat 30, allowing the stop member 40 to operate synchronously with the roller seat 30. In this embodiment, the stop member 40 has a first stop portion 41 and a second stop portion 42. The first stop portion 41 and the first tilt button switch 11 are located on one side of the roller seat 30, and the second stop portion 42 and the second tilt button switch 12 are located on the other side of the roller seat 30.

[0091] Continuing from the above, in this embodiment, the stop member 40 includes a first plate 45 and a second plate 46. The roller seat 30 has a first side 35 and a second side 36 facing each other. The first plate 45 extends integrally from the first side 35 of the roller seat 30, and the second plate 46 extends integrally from the second side 36 of the roller seat 30. The first plate 45 has a first bottom surface 451 facing the substrate 10, and a first stop portion 41 is located at the end of the first bottom surface 451 away from the first side 35. The second plate 46 has a second bottom surface 461 facing the substrate 10, and a second stop portion 42 is located at the end of the second bottom surface 461 away from the second side 36. Therefore, by having the first plate 45 and the second plate 46 of the stop member 40 extend integrally from the roller seat 30, the bonding strength between the stop member 40 and the roller seat 30 can be improved, preventing the stop member 40 from deforming or breaking under stress.

[0092] like Figures 3 to 5 As shown, before the roller seat 30 is operated by the user, the first stop portion 41 of the stop member 40 has a first initial distance S1 between it and the top surface 101 of the substrate 10, and the second stop portion 42 of the stop member 40 has a second initial distance S2 between it and the top surface 101 of the substrate 10. The first initial distance S1 and the second initial distance S2 are greater than or equal to the aforementioned click-press stroke, first press stroke, and second press stroke. For example, assuming that the click-press stroke, first press stroke, and second press stroke are all 0.3 mm, the first initial distance S1 and the second initial distance S2 are greater than or equal to 0.3 mm.

[0093] Figure 6 This is a cross-sectional view of the roller seat of the roller input device of the present invention in the pressing position. Figure 7 This is a side view of the roller seat of the roller input device of the present invention in the pressing position. Figure 6 and Figure 7 As shown, when the roller seat 30 is pressed down by the user and descends to the pressed position (as indicated by arrow L1), the click button switch 15 is pressed and moves the aforementioned click pressing stroke, causing the roller seat 30 to press down and triggering the click button switch 15. The stop member 40 will descend synchronously with the roller seat 30 and approach the top surface 101 of the substrate 10, so that the aforementioned first initial distance S1 and second initial distance S2 (please refer to...) Figure 5The distance between the first and second tilt switches is reduced to a first gap R1, and the first gap R1 is less than the first pressing stroke of the first tilt switch 11 and the second pressing stroke of the second tilt switch 12. For example, assuming that the first pressing stroke of the first tilt switch 11 and the second pressing stroke of the second tilt switch 12 are both 0.3mm, the first gap R1 is less than 0.3mm (for example, the first gap R1 is 0.2mm, 0.1mm or 0mm). Therefore, when the roller seat 30 descends and triggers the click switch 15, the roller seat 30 will be limited by the first stop part 41 and the second stop part 42 of the stop member 40 and will not be able to tilt, or even if the roller seat 30 tilts, it will be stopped by the first stop part 41 or the second stop part 42 and will not be able to trigger the first tilt switch 11 or the second tilt switch 12, thereby avoiding the situation where the user accidentally touches the first tilt switch 11 or the second tilt switch 12 due to improper force.

[0094] Figure 8 This is a side view of the roller seat of the roller input device of the present invention in a first inclined position. Figure 8 As shown, when the roller seat 30 is tilted to the first tilt position by the user in the first lateral direction (as indicated by arrow L2), the first tilt button switch 11 is pressed and moves the first pressing stroke, causing the roller seat 30 to press and trigger the first tilt button switch 11. The first stop part 41 of the stop member 40 will move towards the top surface 101 of the substrate 10 in sync with the roller seat 30, so that the first initial distance S1 (please refer to...) Figure 5 The distance is reduced to a second gap R2, which is less than the click travel of the click button switch 15. For example, assuming the click travel of the click button switch 15 is 0.3mm, the second gap R2 is less than 0.3mm (e.g., the second gap R2 is 0.2mm, 0.1mm, or 0mm). Therefore, when the roller seat 30 triggers the first tilt button switch 11, the roller seat 30 will be limited by the first stop portion 41 of the stop member 40 and will not be able to descend under force, or even if the roller seat 30 is lowered under force, it will be stopped by the first stop portion 41 and will not be able to trigger the click button switch 15, thereby avoiding the situation where the user accidentally touches the click button switch 15 due to improper force.

[0095] Figure 9 This is a side view of the roller seat of the roller input device of the present invention in a second inclined position. Figure 9As shown, similarly, when the roller seat 30 is tilted to the second tilt position by the user (as indicated by arrow L3), the second tilt button switch 12 is pressed and moves the second pressing stroke, causing the roller seat 30 to press and trigger the second tilt button switch 12. The second stop portion 42 of the stop member 40 will move towards the top surface 101 of the substrate 10 in sync with the roller seat 30, so that the second initial distance S2 (please refer to...) Figure 5 The distance is reduced to a third gap R3, which is less than the click travel of the click button switch 15. For example, assuming the click travel of the click button switch 15 is 0.3mm, the third gap R3 is less than 0.3mm (e.g., the third gap R3 is 0.2mm, 0.1mm, or 0mm). Therefore, when the roller seat 30 triggers the second tilt button switch 12, the roller seat 30 will be limited by the second stop portion 42 of the stop member 40 and will not be able to descend under force, or even if the roller seat 30 is lowered under force, it will be stopped by the second stop portion 42 and will not be able to trigger the click button switch 15, thus avoiding the situation where the user accidentally touches the click button switch 15 due to improper force.

[0096] Figure 10 This is a top view of a first embodiment of the roller input device of the present invention, wherein, Figure 10 The roller seat 30 is presented in perspective to clearly show the relative positions of the click button switch 15, the first tilt button switch 11, and the second tilt button switch 12, as will be described below. In this embodiment, the first stop 41 is located between the click button switch 15 and the first tilt button switch 11, and the distance from the first stop 41 to the click button switch 15 is less than the distance from the first stop 41 to the first tilt button switch 11. That is, the first stop 41 is closer to the click button switch 15 to achieve a better stopping and limiting effect. Similarly, the second stop 42 is located between the click button switch 15 and the second tilt button switch 12, and the distance from the second stop 42 to the click button switch 15 is less than the distance from the second stop 42 to the second tilt button switch 12. That is, the second stop 42 is closer to the click button switch 15 to achieve a better stopping and limiting effect.

[0097] For example Figure 10 As shown, the pivot portion 37 of the roller seat 30 has a central axis A, the direction of which is parallel to the roller 50 (see reference). Figure 4As shown, the first stop portion 41 of the stop member 40 and the roller seat 30 have a first axial distance A1 in the direction of the central axis A, and the center of the first tilt button switch 11 and the roller seat 30 have a second axial distance A2 in the direction of the central axis A. The first axial distance A1 is greater than the second axial distance A2 (for example, the first axial distance A1 is 1 to 2 times the second axial distance A2), so that the first stop portion 41 of the stop member 40 can play a better stopping and limiting effect when the roller seat 30 tilts. Similarly, the axial distance between the second stop portion 42 of the stop member 40 and the roller seat 30 in the direction of the central axis A can also be greater than the axial distance between the center of the second tilt button switch 12 and the roller seat 30 in the direction of the central axis A.

[0098] like Figure 10 As shown, in this embodiment, the first tilt button switch 11 and the second tilt button switch 12 are located on the same side of the central axis A, the click button switch 15 and the first tilt button switch 11 are located on opposite sides of the central axis A, the first stop part 41 of the stop member 40 is located between the click button switch 15 and the first tilt button switch 11, the second stop part 42 is located between the click button switch 15 and the second tilt button switch 12, and the first stop part 41, the second stop part 42 and the click button switch 15 are located on the same side of the central axis A.

[0099] For example Figure 10 As shown, in this embodiment, the roller seat 30 has a radial direction D perpendicular to the central axis A. The first stop portion 41 of the stop member 40 and the center of the click button switch 15 have a first radial distance D1 in the radial direction D. The first stop portion 41 and the center of the first tilt button switch 11 have a second radial distance D2 in the radial direction D. The first radial distance D1 can be 1 / 2 to 1 / 3 of the second radial distance D2. In addition, the relative distances between the second stop portion 42 of the stop member 40, the click button switch 15, and the second tilt button switch 12 can also be the same as above, and will not be repeated here.

[0100] In some embodiments, the stop member 40 may also be detachably assembled to the roller seat 30, allowing the user to replace the stop member 40 with one of different shapes or sizes to meet different product requirements. Furthermore, the stop member 40 may also be movable relative to the roller seat 30 to adjust its position, allowing the user to adjust the size of the first initial distance S1 and the second initial distance S2 according to assembly tolerances. This is further explained below with reference to the accompanying drawings.

[0101] Figure 11 This is an exploded perspective view of the second embodiment of the roller input device of the present invention. Figure 12 This is a side view of a second embodiment of the roller input device of the present invention. Figure 13 This is a schematic diagram illustrating the adjustment of a second embodiment of the roller input device of the present invention. Figure 11 and Figure 12 As shown, the difference between this embodiment and the first embodiment described above is at least that the first end 31 of the roller seat 30 in this embodiment also has an assembly part 33, the assembly part 33 has a screw hole 34, the stop member 40a is a bracket and is assembled on the roller seat 30, wherein the stop member 40a has a through hole 43, the through hole 43 is connected to an adjusting screw 60, the adjusting screw 60 is screwed into the screw hole 34 of the roller seat 30, and the assembly part 33 is provided with an elastic member 61, the elastic member 61 abuts against the stop member 40, wherein the elastic member 61 can be a spring, a sheet, or elastic rubber, etc.

[0102] In addition, please refer to Figure 12 and Figure 13 As shown, the first plate 45a and the second plate 46a of the stop member 40a are also located on opposite sides of the roller seat 30, and the first stop portion 41a of the first plate 45a is adjacent to the top surface 101 of the substrate 10, and the second stop portion 42a of the second plate 46a is adjacent to the top surface 101 of the substrate 10. When the user rotates the adjusting screw 60, the stop member 40a can be raised or lowered relative to the roller seat 30 (e.g., ...). Figure 13 (As shown by arrow L4) The height position is adjusted to adjust the distance between the first stop portion 41a and the substrate 10 and the distance between the second stop portion 42a and the substrate 10 to meet assembly tolerances or different product requirements.

[0103] For example Figure 11 As shown, in this embodiment, the stop 40a includes at least one extension arm 47 (in this case, two extension arms 47), one end of each extension arm 47 being pivotally mounted on the roller seat 30. Therefore, when the user rotates the adjusting screw 60, the stop 40a can swing up and down relative to the roller seat 30.

[0104] Figure 14 This is an exploded perspective view of the third embodiment of the roller input device of the present invention. Figure 15 This is a side view of a third embodiment of the roller input device of the present invention. Figure 16 This is a schematic diagram illustrating the adjustment of a third embodiment of the roller input device of the present invention. Figure 14 and Figure 15 As shown, the similarity between this embodiment and the second embodiment described above is at least that the first end 31 of the roller seat 30 in this embodiment also has an assembly part 33 and a screw hole 34. The stop member 40b includes a bracket 44, which has a through hole 43. An adjusting screw 60 is assembled into the through hole 43 and screwed into the screw hole 34 of the roller seat 30. The elastic member 61 abuts against the bracket 44 of the stop member 40b so that the user can adjust the height position of the roller seat 30 by adjusting the adjusting screw 60.

[0105] like Figure 14 and Figure 15As shown, the difference between this embodiment and the second embodiment described above is at least that the stop member 40b further includes a first swing arm 48, a second swing arm 49, and at least one adjusting gear 62 (here, two adjusting gears 62). The two adjusting gears 62 mesh with each other and are rotatably connected to the roller seat 30. The first swing arm 48 and the second swing arm 49 are respectively connected to the two adjusting gears 62. In this embodiment, the two adjusting gears 62 are rotatably connected to the bracket 44 and indirectly connected to the roller seat 30 via the bracket 44. One end of the first swing arm 48 has a tooth 481, which meshes with one of the adjusting gears 62. The first stop portion 41b is located at the other end of the first swing arm 48 and is adjacent to the top surface 101 of the substrate 10. One end of the second swing arm 49 has a tooth 491, which meshes with the other adjusting gear 62. The second stop portion 42b is located at the other end of the second swing arm 49 and is adjacent to the top surface 101 of the substrate 10.

[0106] Therefore, please refer to Figure 14 and Figure 16 As shown, the user can control one of the adjustment gears 62 to rotate via the control component 63, thereby causing the first swing arm 48 and the second swing arm 49 to swing, so as to adjust the distance between the first stop portion 41b and the substrate 10 and the distance between the second stop portion 42b and the substrate 10 according to the assembly tolerance or different product requirements.
