[0044] Figure 1A It is a schematic diagram of the input device of the first embodiment of the present utility model. Figure 1B is Figure 1A an exploded schematic diagram of the roller structure. Figure 1C is Figure 1A a schematic cross-sectional view of the roller structure along the line A1 - A1. Please refer to Figure 1A , in this embodiment, the input device 10 can be a mouse and includes a housing 20 and a roller structure 100. The housing 20 has an opening 21, wherein the roller structure 100 is disposed within the housing 20, and at least a part of the roller structure 100 protrudes out of the housing 20 through the opening 21 to facilitate the user's finger to roll the roller structure 100. In other embodiments, the input device 10 can be a part of a keyboard.

[0045] Please refer to Figures 1A to 1C , in this embodiment, the roller structure 100 includes a support frame 110, a roller rim 120, a positioning frame 130, a magnetic member 140, and two magnets 150 disposed opposite to each other. The support frame 110 is fixed within the housing 20 corresponding to the opening 21 for accommodating a part of the roller rim 120, and another part of the roller rim 120 protrudes out of the housing 20 through the opening 21 to facilitate the user's finger to roll the roller rim 120. On the other hand, a pivot 121 is provided at the center of the roller rim 120 to pivotally connect to the support frame 110 through the pivot 121, so that the roller rim 120 is adapted to rotate about the axis 121a of the pivot 121.

[0046] The positioning frame 130 includes a first body portion 131 and a second body portion 132, wherein the first body portion 131 protrudes from one side of the second body portion 132 and is connected to the support frame 110, for example, fixed to the support frame 110. Further, the first body portion 131 has an extension portion 131a extending along the direction of the axis 121a, and the extension portion 131a is connected to the support frame 110. On the other hand, the second body portion 132 is disposed within the roller rim 120, and at this time, the extension portion 131a of the first body portion 131 protrudes out of the roller rim 120 along the direction of the axis 121a.

[0047] Please refer to Figure 1B and Figure 1C, in this embodiment, the magnetic member 140 is disposed in the circumferential direction of the second body portion 132 or the magnetic member 140 surrounds the second body portion 132, so as to be disposed in the roller rim 120 together with the second body portion 132. Specifically, the magnetic member 140 may be a magnetic ring made of silicon steel or other magnetic materials, sleeved and fixed on the second body portion 132 or integrally formed on the second body portion 132. The magnetic member 140 includes at least one first portion 141 and at least one second portion 142. Taking a plurality of first portions 141 and a plurality of second portions 142 as an example, the plurality of first portions 141 and the plurality of second portions 142 are alternately arranged in the circumferential direction around the axis 121a on the outer peripheral surface of the magnetic ring (i.e., the magnetic member 140) or the second body portion 132. That is to say, one second portion 142 is provided between two adjacent first portions 141, and one first portion 141 is provided between two adjacent second portions 142.

[0048] On the other hand, the second body portion 132 may be a hollow cylinder for the pivot shaft 121 to pass through the second body portion 132 and further pivotally connected to the support frame 110. Specifically, each first portion 141 may be a protrusion protruding along the radial direction D (the direction perpendicular to the axis 121a) of the second body portion 132, and each second portion 142 may be a groove recessed along the radial direction D of the second body portion 132. It should be specifically noted that Figure 1B only one of the plurality of radial directions D arranged radially is schematically shown.

[0049] Please refer to Figure 1B and Figure 1C , in this embodiment, two magnets 150 are correspondingly disposed in the roller rim 120 with respect to the magnetic member 140, for example, fixed to the inner side of the roller rim 120. In addition, the connection line between the two magnets 150 is perpendicular to the axis 121a. Specifically, two positioning grooves 122 are disposed on the radial direction D of the inner side of the roller rim 120, and the two magnets 150 are respectively fixed in the two positioning grooves 122.

[0050] Please refer to Figures 1A to 1C, when the user's finger scrolls the roller frame 120, the magnetic member 140 remains stationary because it is fixed to the support frame 110 through the positioning frame 130, and the magnet 150 rotates synchronously with the roller frame 120 relative to the magnetic member 140 to alternately align with the first part 141 and the second part 142 in the radial direction D of the roller frame 120. The magnet 150 is separated from the opposite first part 141 by a first distance D1 and generates a first magnetic force (such as magnetic attraction or magnetic repulsion), while the magnet 150 is separated from the opposite second part 142 by a second distance D2 greater than the first distance D1 and generates a second magnetic force smaller than the first magnetic force. That is, during the process of the user's finger scrolling the roller frame 120, the magnetic force between each magnet 150 and the magnetic member 140 alternates from large to small or from small to large, so as to generate a clear paragraph feel.

[0051] As Figure 1A shown in Figure 1B , a weight member 160 (i.e., a counterweight ring) can be further provided in the radial direction D of the positioning frame 130. The weight member 160 is arranged on the positioning frame 130 in a direction around the axis 121a. For example, the weight member 160 can be made of stainless steel to increase the weight of the roller frame 120. Accordingly, when the roller frame 120 rotates at a high speed, even if the user no longer scrolls the roller frame 120, the roller frame 120 can still maintain its rotational inertia to overcome the magnetic force and continue to rotate for a period of time.

[0052] The design principles of the roller structures 100A to 100G in the following embodiments are substantially the same as those of the roller structure 100 in the first embodiment. Similar elements will be denoted by the same symbols and will not be described in detail.

Figure 2B is a cross-sectional schematic view of the roller structure according to the second embodiment of the present invention. Please refer to Figure 2A and Figure 2B , the main difference between the roller structure 100A in this embodiment and the first embodiment lies in: the configuration method and structural form of the magnetic member and the magnet.

[0054] In this embodiment, the magnetic member 140a is fixed within the roller rim 120a and surrounds the second body portion 132 of the positioning frame 130a. Specifically, a plurality of first portions 141 and a plurality of second portions 142 of the magnetic member 140a are alternately arranged in a direction around the axis 121a on the inner peripheral surface of the magnetic ring (i.e., the magnetic member 140a). Each first portion 141 may be a protrusion protruding in the direction of the radial D of the second body portion 132, and each second portion 142 may be a groove recessed in the direction of the radial D of the second body portion 132. On the other hand, a plurality of positioning protrusions 123 surrounding the axis 121a are provided on the inner side of the roller rim 120a, and each positioning protrusion 123 is engaged between two adjacent first portions 141 or engaged in a second portion 142 to fix the magnetic member 140a to the roller rim 120a.

Specifically, two positioning grooves 132a are provided on the outer side of the radial D of the second body portion 132, and the two magnets 150 are respectively fixed in the two positioning grooves 132a.

[0056] In this embodiment, when the user's finger rolls the roller rim 120a, each magnet 150 remains stationary because it is fixed to the support frame 110 through the positioning frame 130a, and the magnetic member 140a rotates synchronously with the roller rim 120a relative to the magnet 150, so that the magnet 150 is alternately aligned with the first portion 141 and the second portion 142 in the radial D of the roller rim 120a. The acting manner between the magnet 150 and the magnetic member 140a is similar to that of the foregoing embodiment and will not be elaborated herein.

[0073] Specifically, the motor 170 can drive the limit cam 180 to rotate around the first direction R1 or rotate around the second direction R2 opposite to the first direction R1. The limit cam 180 has an inclined surface 181 that slidably contacts the limiting portion 1303, and the inclined surface 181 can be, for example, a helical surface. The torsion spring 190 is disposed corresponding to the first body portion 1301, wherein one end of the torsion spring 190 is connected to the support frame 110e, and the other end is connected to the positioning frame 130e. The sensing magnet 191 is disposed on the roller rim 120e, and the magnetic sensor 192 is configured to sense information about the sensing magnet 191, for example, to detect the rotation speed of the sensing magnet 191 on the roller rim 120e. The magnetic sensor 192 is electrically coupled to the motor 170 and can be fixed to the support frame 110e corresponding to the sensing magnet 191.

[0074] As Figure 6B and Figure 6D shown, in the first mode (or paragraph mode), the second body portion 1302 of the positioning frame 130e is close to the roller rim 120e. When the user's finger rolls the roller rim 120e, the magnet 150e remains stationary, and the magnetic member 140e rotates synchronously with the roller rim 120e relative to the magnet 150e, so that the first magnetic poles 1511 and the second magnetic poles 1521 are alternately aligned with the first portions 1411 and the second portions 1421 in the axial direction to generate an alternating change of magnetic repulsion and magnetic attraction, and feedback a clear paragraph feel to the user.

[0075] As Figure 6C and Figure 6EAs shown, when the magnetic sensor 192 detects that the rotational speed of the sensing magnet 191 that rotates synchronously with the roller rim 120e is greater than or equal to a predetermined value, the control motor 170 drives the limit cam 180 to rotate around the first direction R1, so as to push the limiting portion 1303 by the inclined surface 181 of the limit cam 180, driving the whole positioning frame 130e to rotate around the third direction R3, so that the second body portion 1302 can move axially away from the roller rim 120e approximately. At this time, the torsion spring 190 is compressed and stores elastic potential energy. Herein, because the second body portion 1302 is inclined relative to the roller rim 120e, there is a first distance D1 between the magnet 150e on the second body portion 1302 and the first part 1411 of the magnetic member 140e on the roller rim 120e, and there is a second distance D2 different from the first distance D1 between the magnet 150e on the second body portion 1302 and the second part 1421 of the magnetic member 140e on the roller rim 120e. This is the second mode, or the shuttle mode.

[0076] In the second mode (shuttle mode), since the distance between the magnet 150e on the second body portion 1302 and the magnetic member 140e on the roller rim 120e is increased, the acting magnetic force between the magnet 150e and the magnetic member 140e is weakened, and the paragraph feeling generated by their interaction is eliminated. Therefore, a rolling feeling without resistance or with less resistance is feedback to the user.

[0077] Accordingly, when the roller rim 120e rotates at a high speed and the magnetic sensor 192 senses that the rotational speed of the roller rim 120e reaches the predetermined value, the input device switches from the first mode to the second mode, enabling the roller rim 120e to move in a manner without resistance or with less resistance.

[0078] Relatively, it can be set that when the magnetic sensor 192 detects that the rotational speed of the sensing magnet 191 that rotates synchronously with the roller rim 120e is less than the predetermined value, the control motor 170 drives the limit cam 180 to rotate around the second direction R2, so that the elastic force of the compressed torsion spring 190 is released and pushes the whole positioning frame 130e to rotate around the fourth direction R4 opposite to the third direction R3, so that the second body portion 1302 can move axially close to the roller rim 120e approximately, and the input device returns to the first mode. That is to say, by moving the positioning frame 130 to change the relative position or distance between the magnet 150e and the magnetic member 140e, it is possible to switch between the paragraph mode with a greater feedback resistance and the shuttle mode with a smaller feedback resistance.

[0079] Figure 7A It is a schematic diagram of the roller structure in the first mode of the seventh embodiment of the present invention. Figure 7B is Figure 7A a schematic diagram of the roller structure converted to the second mode. Please refer to Figure 7A andFigure 7B The main difference between the roller structure 100G of this embodiment and that of the sixth embodiment lies in the arrangement and structural form of the magnetic member and the magnet.

[0080] In this embodiment, the magnetic member 140g can be a magnetic ring fixed on the roller rim 120g, and includes a plurality of first portions 1412 and a plurality of second portions 1422 that are arranged alternately around the axis 1212 on the outer peripheral surface of the magnetic ring (i.e., the magnetic member 140g). Each first portion 1412 can be a magnetic protrusion protruding along a direction (radial direction D) perpendicular to the axis 1212, and each second portion 1422 can be a magnetic groove recessed along the radial direction D. On the other hand, the magnet 150g is fixed on the second body portion 1302 corresponding to the magnetic member 140g in the radial direction D of the roller rim 120g.

[0081] In the first mode, the magnet 150g is close to the magnetic member 140g, with a first distance D1 between it and the relatively positioned first portion 1412, generating a first magnetic force, and a second distance D2 greater than the first distance D1 between it and the relatively positioned second portion 1422, generating a second magnetic force smaller than the first magnetic force. The alternating change of the magnetic force generated by rolling the roller rim 120g provides a distinct paragraph feel.

[0082] In the second mode, the second body portion 1302 moves away from the magnetic member 140g, and the distance between the magnet 150g on the second body portion 1302 and the magnetic member 140g on the roller rim 120g increases, thus weakening the magnetic force acting on the roller rim 120g. Accordingly, the roller rim 120g can roll with no resistance or less resistance feedback.

[0083] The quantity, position, or arrangement mode of each element in the above embodiment can be adjusted according to design requirements.

[0084] In summary, the input device of the present utility model integrates a non-contact feel feedback design in the roller structure, so as to generate a distinct paragraph feel through the alternating change of magnetic force during the process of the user's finger rolling the roller rim. On the other hand, based on this non-contact feel feedback design, it can prevent the problem of deterioration of the paragraph feel caused by wear, which not only helps to improve the operation experience, but also helps to extend the service life of the input device or reduce the failure rate of the input device. In addition, by moving the positioning frame to change the relative position or distance between the magnet and the magnetic member, it is possible to switch between a paragraph mode with a larger feedback resistance and a shuttle mode with a smaller feedback resistance.
