Description

Technical Field

[0001] The invention relates to an input device, in particular to a roller input device. Background Art

[0002] Generally, a computer is often equipped with a scroll wheel input device, such as a keyboard or a mouse, so that actions such as dragging, scrolling pages up and down, or switching menus can be performed through the scroll wheel input device.

[0003] In order to meet the user's more diverse usage requirements, some special types of roller input devices provide the roller wheel with other operation modes (for example, the user can control the roller wheel to swing) in addition to the rotation and pressing operations to generate different functions.

[0004] However, since the roller can move in multiple directions, if the user's force application angle or force size is slightly deviated, it is easy to cause misoperation. For example, the user originally only wanted to control the roller to swing, but if the user accidentally applies too much force, the roller may drop 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 substrate, a bracket group, a roller seat and a stopper. The substrate has a top surface, and a click button switch and a first tilt button switch are provided on the top surface. The click button switch has a click pressing stroke, and the first tilt button switch has a first pressing stroke. The bracket group is arranged on the substrate and includes a first bracket and a second bracket, and the first bracket and the second bracket are arranged at intervals from each other. The roller seat is arranged on the substrate and is located between the first bracket and the second bracket. The roller seat includes a first end and a second end opposite to each other. The first end can be pivoted to the first bracket and the second end can be pivoted to the second bracket. The click button switch is adjacent to the first end, and the roller seat can selectively descend to the substrate to a pressing position or tilt to the first side to a first tilt position. The stopper is connected to the roller seat, and the stopper has a first stopper. The first stopper and the first tilt button switch are located on one side of the roller seat, and there is a first initial spacing between the first stopper and the top surface of the substrate. When the roller seat is in the pressing position, the roller seat presses and triggers the click button switch, and the first initial spacing is reduced to the first spacing, and the first spacing is smaller than the first pressing stroke of the first tilt button switch; when the roller seat is in the first tilted position, the roller seat presses and triggers the first tilted button switch, and the first initial spacing is reduced to the second spacing, and the second spacing is smaller than the click pressing stroke of the click button switch.

[0006] In summary, according to the roller input device of the embodiment of the present invention, when the roller seat is in the pressing position and presses to trigger the click button switch, the distance between the first stop portion of the stopper and the top surface of the substrate is reduced and is smaller 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 presses to trigger the first tilt button switch, the distance between the first stop portion of the stopper and the top surface of the substrate is reduced and is smaller than the click pressing stroke of the click button switch, so as to prevent the roller seat from descending and accidentally touching the click button switch, thereby avoiding malfunctions caused by improper force applied by the user.

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

[0087] like Figures 3 to 5 As shown, the roller seat 30 is disposed on the base plate 10 for the roller 50 to be assembled, and the roller seat 30 is located between the first bracket 21 and the second bracket 22. In this embodiment, the roller seat 30 is a hollow shell and has a groove 38, and the roller seat 30 has a pivoting portion 37 (for example, the pivoting portion 37 can be at least one shaft hole or a pivot) for the roller 50 to be pivoted. Here, a partial area of ​​the roller 50 (here, the lower half area) is located in the groove 38, and the axis of the roller 50 is pivoted at the pivoting portion 37 of the roller seat 30, so that the roller 50 can rotate relative to the roller seat 30 when being manipulated. In addition, please refer to Figure 1 and Figure 2 As shown, a partial area (here, the upper half area) of the scroll wheel 50 can be exposed outside the housing of the keyboard 2 or the mouse 3 for user manipulation.

[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 bracket 21 and the second end 32 is pivotally mounted on the second bracket 22. In this embodiment, the first bracket 21 has a guide slot 211, wherein the extending direction of the guide slot 211 is perpendicular to the base plate 10. The first end 31 of the roller seat 30 has a first pivot 311, which is pivotally mounted in the guide slot 211, so that the first pivot 311 can not only rotate relative to the first bracket 21, but also can be lifted and lowered along the guide slot 211. The second bracket 22 has an axial hole 222, and the second end 32 of the roller seat 30 has a second pivot 321, which is pivotally mounted in the axial hole 222, so that the second pivot 321 can rotate relative to the second bracket 22. Thereby, the roller seat 30 can selectively rotate, tilt, or move up and down relative to the bracket assembly 20 through 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 used to abut against the first end 31 of the roller seat 30, so that the roller seat 30 can be maintained at a predetermined height position, and 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, and the user can manipulate the roller 50 and the roller seat 30 to perform lifting and tilting relative to the substrate 10, so that the roller seat 30 can selectively descend toward the substrate 10 to a pressing position to press the click button switch 15, or tilt toward a first lateral direction to a first tilted position to press and trigger the first tilt button switch 11, or tilt toward a second lateral direction opposite to the first lateral direction to a second tilted 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 stopper 40 can be a plate, a block or a bracket and connected to the roller seat 30, wherein the stopper 40 can be integrally connected to the roller seat 30 or detachably assembled to the roller seat 30, so that the stopper 40 can be synchronously actuated with the roller seat 30. In this embodiment, the stopper 40 has a first stopper portion 41 and a second stopper portion 42, the first stopper portion 41 and the first tilt button switch 11 are located on one side of the roller seat 30, and the second stopper portion 42 and the second tilt button switch 12 are located on the other side of the roller seat 30.

[0091] As mentioned above, in this embodiment, the stopper 40 includes a first plate 45 and a second plate 46, the roller seat 30 has a first side surface 35 and a second side surface 36 opposite to each other, the first plate 45 extends integrally from the first side surface 35 of the roller seat 30, the second plate 46 extends integrally from the second side surface 36 of the roller seat 30, the first plate 45 has a first bottom surface 451 facing the substrate 10, the first stopper 41 is located at the end of the first bottom surface 451 away from the first side surface 35, the second plate 46 has a second bottom surface 461 facing the substrate 10, and the second stopper 42 is located at the end of the second bottom surface 461 away from the second side surface 36. Thus, by the first plate 45 and the second plate 46 of the stopper 40 extending integrally from the roller seat 30, the combination strength between the stopper 40 and the roller seat 30 can be improved, and the stopper 40 can be prevented from being deformed or broken due to force.

[0092] like Figures 3 to 5 As shown, before the roller seat 30 is operated by the user, there is a first initial spacing S1 between the first stopper 41 of the stopper 40 and the top surface 101 of the substrate 10, and there is a second initial spacing S2 between the second stopper 42 of the stopper 40 and the top surface 101 of the substrate 10, wherein the first initial spacing S1 and the second initial spacing S2 are greater than or equal to the above-mentioned click pressing stroke, the first pressing stroke, and the second pressing stroke. For example, assuming that the click pressing stroke, the first pressing stroke, and the second pressing stroke are all 0.3 mm, the first initial spacing S1 and the second initial spacing S2 are greater than or equal to 0.3 mm.

[0093] Figure 6 is a cross-sectional view of the roller seat of the roller input device of the present invention at the pressing position, Figure 7 FIG. 1 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 by the user and descends (as shown by arrow L1) to the pressing position, the click button switch 15 is pressed and moves the above-mentioned click pressing stroke, so that the roller seat 30 presses and triggers the click button switch 15, and the stopper 40 will move toward the top surface 101 of the substrate 10 along with the roller seat 30, so that the above-mentioned first initial distance S1 and the second initial distance S2 (please refer to Figure 5As shown in the figure, the first spacing R1 is reduced to a first spacing R1, and the first spacing R1 is smaller than the first pressing stroke of the first tilt button switch 11 and the second pressing stroke of the second tilt button switch 12. For example, assuming that the first pressing stroke of the first tilt button switch 11 and the second pressing stroke of the second tilt button switch 12 are both 0.3 mm, the first spacing R1 is smaller than 0.3 mm (for example, the first spacing R1 is 0.2 mm, 0.1 mm or 0 mm). Therefore, when the roller seat 30 descends and triggers the click button switch 15, the roller seat 30 will be limited by the first stop portion 41 and the second stop portion 42 of the stop member 40 and cannot tilt, or even if the roller seat 30 tilts, it will be stopped by the first stop portion 41 or the second stop portion 42 and cannot trigger the first tilt button switch 11 or the second tilt button switch 12, so as to avoid the situation where the user applies improper force and accidentally touches the first tilt button switch 11 or the second tilt button switch 12.

[0094] Figure 8 FIG. 4 is a side view of the roller seat of the roller input device of the present invention in the first tilted position. Figure 8 As shown, when the roller seat 30 is manipulated by the user to tilt toward the first lateral direction (as shown by arrow L2) to the first tilt position, the first tilt button switch 11 is pressed and moves the first pressing stroke, so that the roller seat 30 presses and triggers the first tilt button switch 11, and the first stopper 41 of the stopper 40 will move toward the top surface 101 of the substrate 10 with the synchronous swing of the roller seat 30, so that the first initial distance S1 (please refer to Figure 5 The second spacing R2 is reduced to the second spacing R2, and the second spacing R2 is smaller than the click pressing stroke of the click button switch 15. For example, assuming that the click pressing stroke of the click button switch 15 is 0.3 mm, the second spacing R2 is smaller than 0.3 mm (for example, the second spacing R2 is 0.2 mm, 0.1 mm or 0 mm). Therefore, when the roller seat 30 triggers the first tilt button switch 11, the roller seat 30 will be limited by the first stopper 41 of the stopper 40 and cannot be forced to move downward, or even if the roller seat 30 is forced to move downward, it will be stopped by the first stopper 41 and cannot trigger the click button switch 15, so as to avoid the situation where the user applies improper force and accidentally touches the click button switch 15.

[0095] Fig. 9 FIG. 4 is a side view of the roller seat of the roller input device of the present invention in the second inclined position. Fig. 9Similarly, when the roller seat 30 is manipulated by the user to tilt toward the second lateral direction (as shown by arrow L3) to the second tilt position, the second tilt button switch 12 is pressed and moves the second pressing stroke, so that the roller seat 30 presses and triggers the second tilt button switch 12, and the second stopper 42 of the stopper 40 will move toward the top surface 101 of the substrate 10 with the synchronous swing of the roller seat 30, so that the second initial distance S2 (please refer to Figure 5 The third spacing R3 is reduced to a third spacing R3, and the third spacing R3 is smaller than the click pressing stroke of the click button switch 15. For example, assuming that the click pressing stroke of the click button switch 15 is 0.3 mm, the third spacing R3 is smaller than 0.3 mm (for example, the third spacing R3 is 0.2 mm, 0.1 mm or 0 mm). Therefore, when the roller seat 30 triggers the second tilt button switch 12, the roller seat 30 will be limited by the second stopper 42 of the stopper 40 and cannot be forced to move downward, or even if the roller seat 30 is forced to move downward, it will be stopped by the second stopper 42 and cannot trigger the click button switch 15, so as to avoid the situation where the user applies improper force and accidentally touches the click button switch 15.

[0096] Fig.10 It is a top view of the first embodiment of the roller input device of the present invention, wherein: Fig.10 The roller seat 30 is presented in a perspective manner to clearly present the relative positions of the click button switch 15, the first tilt button switch 11 and the second tilt button switch 12, which will be described first. In this embodiment, the first stopper 41 is located between the click button switch 15 and the first tilt button switch 11, and the distance from the first stopper 41 to the click button switch 15 is smaller than the distance from the first stopper 41 to the first tilt button switch 11, that is, the first stopper 41 is closer to the click button switch 15, so as to exert a better stopper and limit effect. Similarly, the second stopper 42 is located between the click button switch 15 and the second tilt button switch 12, and the distance from the second stopper 42 to the click button switch 15 is smaller than the distance from the second stopper 42 to the second tilt button switch 12, that is, the second stopper 42 is closer to the click button switch 15, so as to exert a better stopper and limit effect.

Similarly, the axial spacing between the second stopper 42 of the stopper 40 and the roller seat 30 in the direction of the central axis A can also be greater than the axial spacing between the center of the second tilt button switch 12 and the roller seat 30 in the direction of the central axis A.
