Description

TECHNICAL FIELD

[0001] The present invention relates to an input device, and more particularly to a scroll wheel input device. BACKGROUND

[0002] Generally, a computer is often equipped with a scroll wheel input device, such as a keyboard or a mouse, to perform actions such as dragging, scrolling a page up or down, or switching a menu, by means of the scroll wheel input device.

[0003] A conventional scroll wheel input device generally has a scroll wheel and an elastic member. The scroll wheel body is provided with a tooth surface, and the elastic member is abutted against the tooth surface of the scroll wheel body. When the scroll wheel is rotated by operation, the elastic member generates a stop touch feeling. For example, when the scroll wheel is rotated by one scale, the operator will feel a stop touch feeling, and the screen page is scrolled by a predetermined distance. However, the scroll wheel input device of the above-mentioned mechanism type still cannot meet some use conditions, such as long-time or long-distance scrolling of the scroll wheel, or more subtle scrolling operation. SUMMARY

[0004] In view of the above, in one embodiment, a scroll wheel input device is provided, which includes a base, a scroll wheel module, a movable member, and a second magnetic member. The base has a first sliding slot and a first pivot portion. The scroll wheel module is rotatably arranged on the base, and includes a scroll wheel body and a plurality of first magnetic members. The plurality of first magnetic members are connected to the scroll wheel body and arranged in a ring shape. The movable member has a first oblique guide slot and a second pivot portion. The second pivot portion is pivotally arranged on the first pivot portion of the base, so that the movable member can be selectively swung between a first position and a second position relative to the base. The first oblique guide slot has opposite first and second ends. The second magnetic member is slidably arranged in the first sliding slot of the base and adjacent to one of the plurality of first magnetic members. The second magnetic member has a first guide column located in the first oblique guide slot of the movable member. When the movable member is located at the first position, the first guide column is located at the first end, so that the second magnetic member and the adjacent first magnetic member have a first magnetic attraction force. When the movable member is swung from the first position to the second position, the first guide column moves from the first end to the second end, so that the second magnetic member approaches the adjacent first magnetic member and has a second magnetic attraction force. The first magnetic attraction force is smaller than the second magnetic attraction force.

[0005] In one embodiment, one side of the scroll wheel body has an inner recess, and the inner recess has an inner ring surface. The plurality of first magnetic members are arranged in a ring shape on the inner ring surface.

[0006] In one embodiment, the first sliding slot of the base is located in the inner recess.

[0007] In one embodiment, one side of the scroll wheel body has a plurality of recesses arranged in a ring shape, and the plurality of first magnetic members are respectively fixed in the plurality of recesses.

[0008] In one embodiment, the second magnetic member has at least one protrusion, the first sliding slot of the base has an inner surface, and the second magnetic member contacts the inner surface with the at least one protrusion.

[0009] In one embodiment, the base has a stopper with a buffer on the stopper, and the movable member has a limit portion, and the limit portion abuts against the buffer when the movable member is in the first position or the second position.

[0010] In one embodiment, the first sliding slot of the base has a buffer block inside, and the second magnetic member abuts against the buffer block when the movable member is in the first position or the second position.

[0011] In one embodiment, the base has a first side surface, the first pivot portion is on the first side surface, and the first side surface has at least one protrusion; the movable member has a second side surface facing the first side surface, and the at least one protrusion contacts the second side surface.

[0012] In one embodiment, the second magnetic member has a sliding block and a magnetic body, the first guide column is disposed on the sliding block, and the sliding block has an embedding slot, and the magnetic body is embedded in the embedding slot.

[0013] In one embodiment, the base has a second sliding slot, and the second sliding slot and the first sliding slot are respectively on opposite sides of the first pivot portion.

[0014] The movable member has a second oblique guide slot, and the second oblique guide slot and the first oblique guide slot are respectively on opposite sides of the second pivot portion.

[0015] The third magnetic member is slidably disposed in the second sliding slot of the base, and the third magnetic member is adjacent to another one of the plurality of first magnetic members, the third magnetic member has a second guide column, and the second guide column is in the second oblique guide slot of the movable member.

[0016] In one embodiment, the base has a limit column, the movable member has an arc-shaped guide slot, and the limit column is slidably disposed in the arc-shaped guide slot; when the movable member is in the first position, the limit column is at one end of the arc-shaped guide slot, and when the movable member is in the second position, the limit column is at the other end of the arc-shaped guide slot.

[0017] In one embodiment, one of the first pivot portion and the second pivot portion is a cylinder, and the other is a polygonal hole.

[0018] In one embodiment, the roller input device further comprises a switching assembly connected to the movable member and used to drive the movable member to swing relative to the base between the first position and the second position.

[0019] In one embodiment, the switching assembly includes a sliding seat, a spring and a torsion spring. The sliding seat is movably connected to the base. The sliding seat has a top portion and a bottom portion. The top portion contacts one end of the movable member. The spring is positioned between the base and the sliding seat. One end of the torsion spring is connected to the base. The other end of the torsion spring is connected to the movable member.

[0020] In one embodiment, the sliding seat has a ring-shaped sliding groove. The ring-shaped sliding groove has a first recess and a second recess. The switching assembly includes a limiting member. The limiting member has a fixed end and a movable end. The fixed end is fixed to the base. The movable end is slidably arranged in the ring-shaped sliding groove. When the movable member is in the first position, the movable end of the limiting member is limited in the first recess. When the movable member is in the second position, the movable end of the limiting member is limited in the second recess.

[0021] In summary, according to the roller input device of the embodiment of the present application, the user can control the movable member to move in the first position or the second position to switch different operation modes. When the movable member is in the first position, the second magnetic member has a first magnetic attraction with the adjacent first magnetic member. When the movable member is swung from the first position to the second position, the first inclined guide groove can directly drive the first guide column of the second magnetic member to move from the first end to the second end, so that the second magnetic member approaches the adjacent first magnetic member and has a second magnetic attraction. The first magnetic attraction is smaller than the second magnetic attraction (for example, the first magnetic attraction is 0 or much smaller than the second magnetic attraction). Therefore, when the movable member is in the first position, the roller module can be rotated without resistance, so as to be quickly rotated or more finely operated, to be suitable for some use cases (for example, the roller needs to be rotated for a long time or a long distance, or more subtle scrolling operation is needed). When the movable member is in the second position, the second magnetic member and the plurality of first magnetic members can have a magnetic attraction change to generate a segment touch feeling when the roller module is rotated, to achieve the advantages of avoiding mechanical errors, reducing operating noise, and reducing friction loss.

[0097] Figure 1 FIG. 1 is a perspective view of a roller input device according to an embodiment of the present application, Figure 2 FIG. 2 is a perspective view of a roller input device according to another embodiment of the present application, Figure 3 FIG. 1 is a perspective view of a roller input device according to an embodiment of the present application, Figures 1 to 3 As shown in FIG. 1, the roller input device 1 according to an embodiment of the present application is an input device of a computer, and is used to control the computer to perform actions such as dragging, scrolling, or switching pages. In some embodiments, the roller input device 1 can be applied to a keyboard 2 of the computer. Figure 1or, the scroll input device 1 can also be applied to a mouse 3 of a computer (as shown in Figure 2 For example, the scroll input device 1 can be installed inside the housing of the keyboard 2 or the mouse 3.

[0098] Figure 4 A perspective view of a first embodiment of the scroll input device of the present application is shown in Figure 3 As shown in Figure 4 The scroll input device 1 comprises a base 10, a scroll module 20, a movable member 30, a second magnetic member 40 and a third magnetic member 50, wherein the scroll module 20, the movable member 30, the second magnetic member 40 and the third magnetic member 50 are all arranged on the base 10.

[0099] As shown in Figure 3 As shown in Figure 4 The base 10 has a first sliding groove 11, a second sliding groove 12 and a first pivot joint 15. In this embodiment, the base 10 has a U-shaped plate 18, the first sliding groove 11 and the second sliding groove 12 are formed inside the U-shaped plate 18, and the first pivot joint 15 is located between the first sliding groove 11 and the second sliding groove 12, that is, the first sliding groove 11 and the second sliding groove 12 are respectively located on the opposite sides of the first pivot joint 15.

[0100] As shown in Figure 3 As shown in Figure 4 The scroll module 20 is rotatably arranged on the base 10, that is, the scroll module 20 can rotate relative to the base 10 when it is manipulated by a user. For example, in this embodiment, the base 10 is a hollow housing and has an assembly groove 17. A partial region (here, the lower half region) of the scroll module 20 is located inside the assembly groove 17, and the axis of the scroll module 20 is pivotally arranged on the base 10, so that the scroll module 20 can rotate relative to the base 10 when it is manipulated. In addition, please refer to Figure 1 As shown in Figure 2 A partial region (here, the upper half region) of the scroll module 20 can be exposed to the keyboard 2 or the mouse 3 for manipulation by a user.

[0101] As shown in Figure 3 As shown in Figure 4 The scroll module 20 comprises a scroll body 21 and a plurality of first magnetic members 25, the plurality of first magnetic members 25 are connected to the scroll body 21 and arranged in a ring shape, wherein the scroll body 21 and the plurality of first magnetic members 25 can be integrally connected to form a one-piece structure (as shown in Figure 4 Alternatively, the plurality of first magnetic members 25 and the scroll body 21 can also be an assembled structure.

[0102] As shown in Figure 3 As shown in Figure 4As shown, in this embodiment, the roller body 21 of the roller module 20 has an inner groove 22 on one side, and the inner groove 22 has an inner annular surface 221. A plurality of first magnetic elements 25 are arranged in a ring on a plurality of protrusions of the inner annular surface 221. The roller body 21 and the plurality of first magnetic elements 25 can be made of magnetically conductive materials such as iron, cobalt, nickel, or silicon steel, or composite materials, and thus possess magnetic properties. The plurality of first magnetic elements 25 maintain a distance from each other and do not contact each other. The plurality of first magnetic elements 25 are integrally connected to the inner annular surface 221 of the roller body 21, but this is not a limitation. In some embodiments, the plurality of first magnetic elements 25 can also be integrally connected to form a single, integrally molded structure.

[0103] like Figure 3 and Figure 4 As shown, the movable member 30 has a first inclined guide groove 31, a second inclined guide groove 32, and a second pivot portion 35. The second pivot portion 35 is pivotally mounted to the first pivot portion 15 of the base 10, allowing the movable member 30 to swing relative to the base 10 between a first position and a second position about the second pivot portion 35 as an axis. In some embodiments, one of the first pivot portion 15 of the base 10 and the second pivot portion 35 of the movable member 30 may be a cylinder, and the other may be a hole. For example... Figure 4 As shown, in this embodiment, the first pivot portion 15 of the base 10 is a cylinder, and the second pivot portion 35 of the movable member 30 is a hole. The first pivot portion 15 (cylinder) passes through the second pivot portion 35 and is pivotally connected to each other. Preferably, the second pivot portion 35 is a square hole, so that the first pivot portion 15 and the second pivot portion 35 form a line contact rather than a surface contact. In this way, when the movable member 30 rotates relative to the base 10 with the second pivot portion 35 as the axis, the frictional resistance can be greatly reduced, making the operation smoother.

[0104] like Figure 3 and Figure 4 As shown, the movable component 30 is composed of multiple plates. In this embodiment, the movable component 30 includes a first side plate 33 and a second side plate 34. The first side plate 33 and the second side plate 34 are respectively located on opposite sides of the roller module 20. A first inclined guide groove 31, a second inclined guide groove 32 and a second pivot part 35 are disposed on the first side plate 33, and the first inclined guide groove 31 and the second inclined guide groove 32 are respectively located on opposite sides of the second pivot part 35.

[0105] Figure 5 This is a side view of the movable member in the first position of the first embodiment of the roller input device of the present invention. Figure 6 for Figure 5 A sectional view along line segment 6-6. (e.g.) Figure 4 and Figure 6As shown, the first inclined guide groove 31 of the movable member 30 has a first end 311 and a second end 312 opposite to each other, wherein the first end 311 and the second end 312 are located at different height positions, and one end of the first inclined guide groove 31 (here, the first end 311) is adjacent to the second pivot portion 35 relative to the other end (here, the second end 312), so that the first inclined guide groove 31 is inclined rather than horizontal or vertical. In addition, the first inclined guide groove 31 has a first guide slope 313 and a second guide slope 314, which are parallel to each other and connected between the first end 311 and the second end 312. The structure of the second inclined guide groove 32 of the movable member 30 is the same as or similar to that of the first inclined guide groove 31, and will not be repeated here.

[0106] like Figure 4 and Figure 6 As shown, the second magnetic element 40 is slidably disposed within the first groove 11 of the base 10, and the second magnetic element 40 is adjacent to one of the plurality of first magnetic elements 25. The third magnetic element 50 is slidably disposed within the second groove 12 of the base 10, and the third magnetic element 50 is adjacent to another of the plurality of first magnetic elements 25. That is, the second magnetic element 40 and the third magnetic element 50 are respectively adjacent to different first magnetic elements 25. In this embodiment, a partial area of ​​the U-shaped plate 18 of the base 10 passes into the inner groove 22 of the roller body 21, so that the first groove 11 and the second groove 12 are located in the inner groove 22. Therefore, the second magnetic element 40 in the first groove 11 and the third magnetic element 50 in the second groove 12 can be adjacent to two of the first magnetic elements 25 on the inner annular surface 221 of the inner groove 22.

[0107] like Figures 4 to 6 As shown, the second magnetic component 40 has a first guide post 45 located within the first inclined guide groove 31 of the movable component 30, and the third magnetic component 50 has a second guide post 55 located within the second inclined guide groove 32 of the movable component 30. Thus, when the movable component 30 rotates relative to the base 10, the first inclined guide groove 31 can be moved relative to the second magnetic component 40 via the first guide post 45, causing the second magnetic component 40 to approach or move away from the corresponding first magnetic component 25. Similarly, the second inclined guide groove 32 can be moved relative to the third magnetic component 50 via the second guide post 55, causing the third magnetic component 50 to approach or move away from the corresponding first magnetic component 25.

[0108] In some embodiments, each of the first magnetic elements 25 may be made of magnetically conductive materials or composite materials such as iron, cobalt, nickel, or silicon steel, and the second magnetic element 40 and the third magnetic element 50 may have permanent magnets (such as neodymium iron boron magnets or AlNiCo magnets); or, each of the first magnetic elements 25 may also be a permanent magnet, and the second magnetic element 40 and the third magnetic element 50 may be made of magnetically conductive materials or composite materials such as iron, cobalt, nickel, or silicon steel, so that the second magnetic element 40 may have magnetic attraction when it is close to the corresponding first magnetic element 25, and the third magnetic element 50 may have magnetic attraction when it is close to the corresponding first magnetic element 25.

[0109] like Figure 4 As shown, in this embodiment, each of the first magnetic components 25 is made of magnetically conductive materials or composite materials such as iron, cobalt, nickel, or silicon steel. The second magnetic component 40 and the third magnetic component 50 have the same or similar structures. Taking the second magnetic component 40 as an example, the second magnetic component 40 has a slider 41 and a magnetic body 42. The slider 41 can be made of metal or plastic. The first guide post 45 is disposed on the slider 41, and the slider 41 has a groove 411. The magnetic body 42 is a permanent magnet (such as a neodymium iron boron magnet or an AlNiCo magnet) and is fitted into the groove 411. In addition, in this embodiment, the magnetic body 42 and the groove 411 of the second magnetic component 40 are T-shaped, so that after the magnetic body 42 is fitted into the groove 411, it can prevent the magnetic body 42 from detaching from the groove 411. However, this is not a limitation, and the shape of the magnetic body 42 and the groove 411 of the second magnetic component 40 can also be L-shaped, U-shaped, or other irregular shapes.

[0110] In some embodiments, the slider 41 of the second magnetic element 40 may be made of a self-lubricating material, such as graphite, molybdenum disulfide (MoS2), polytetrafluoroethylene (PTFE), ceramic, or a composite material formed from at least two of these materials. This effectively reduces the frictional force when the second magnetic element 40 slides relative to the first slide groove 11, making the movement of the second magnetic element 40 smoother. Alternatively, lubricating oil may be added between the second magnetic element 40 and the first slide groove 11, achieving the same effect of reducing friction. Furthermore, the third magnetic element 50 and the second slide groove 12 may also have the same or similar configuration as described above, which will not be repeated here.

[0111] In some embodiments, when the movable member 30 is in the first position, a first magnetic attraction force may exist between the second magnetic member 40 and the adjacent first magnetic member 25, and between the third magnetic member 50 and the adjacent first magnetic member 25. When the movable member 30 is in the second position, a second magnetic attraction force may exist between the second magnetic member 40 and the adjacent first magnetic member 25, and between the third magnetic member 50 and the adjacent first magnetic member 25, and the first magnetic attraction force is less than the second magnetic attraction force (e.g., the first magnetic attraction force is 0 or much less than the second magnetic attraction force) to produce different operating feel, which is further explained below with reference to the accompanying drawings.

[0112] As Figure 5 with Figure 6 shown, when the movable member 30 is swung to the first position (as Figure 5 shown) relative to the base 10, the first guide post 45 of the second magnetic member 40 is located at the first end 311 of the first inclined guide slot 31, and the second magnetic member 40 is located closer to the first end of the first slide slot 11 adjacent to the first pivot portion 15 (as Figure 6 shown), so that the second magnetic member 40 and the adjacent first magnetic member 25 are kept apart and have the first magnetic attraction force as described above. The second guide post 55 of the third magnetic member 50 is located at the first end of the second inclined guide slot 32 adjacent to the first pivot portion 15, and the third magnetic member 50 is located closer to the first end of the second slide slot 12 adjacent to the first pivot portion 15 (as Figure 6 shown), so that the third magnetic member 50 and the adjacent first magnetic member 25 are kept apart and have the first magnetic attraction force as described above. In this way, the roller module 20 can be rotated without resistance and can be rotated quickly or more delicately, so as to be suitable for some use cases (for example, the roller needs to be rotated for a long time or a long distance, or more delicate scrolling operation is needed).

[0113] Figure 7 In order to Figure 5 the cross-sectional view along the 7-7 line. As Figure 4 with Figure 7 shown, preferably, in the present embodiment, the base 10 has a first side surface 14, the first pivot portion 15 is located on the first side surface 14, the first side surface 14 has at least one protrusion 141, the movable member 30 has a second side surface 37 facing the first side surface 14, and the end of the protrusion 141 contacts the second side surface 37 of the movable member 30, so that the movable member 30 can be limited and prevented from shaking, and point contact can be formed between the base 10 and the movable member 30 instead of surface contact. In this way, when the movable member 30 is swung relative to the base 10, the frictional resistance can be greatly reduced, and the movement can be smoother. In addition, in the present embodiment, the number of protrusions 141 is multiple (here, 7 protrusions 141, but this is not limited), and the ends of the multiple protrusions 141 contact different positions of the second side surface 37 of the movable member 30 to form multiple point contacts, so that the movable member 30 can be more stable when it is swung.

[0114] Figure 8 is a side view of the movable member of the first embodiment of the roller input device of the present application at the second position, Figure 9 is Figure 8 a cross-sectional view along the 9-9 line, Figure 10 is a cross-sectional view of the movable member of the first embodiment of the roller input device of the present application at the second position. As Figures 8 to 10 shown, when the movable member 30 is swung to the second position (as Figure 5to the second position (as shown in Figure 8 When the movable member 30 is swung from the second position (as shown in Figure 9 to the first position (as shown in Figure 10 ), the first inclined guide slot 31 can drive the first guide column 45 of the second magnetic member 40 to move from the first end 311 to the second end 312 of the first inclined guide slot 31, so that the second magnetic member 40 moves along the first sliding slot 11 to approach the adjacent first magnetic member 25. When the movable member 30 is in the second position, the second magnetic member 40 is closer to the first sliding slot 11 away from the first pivot portion 15 (as shown in Similarly, since the second inclined guide slot 32 is inclinedly arranged instead of horizontally or vertically, the second inclined guide slot 32 can drive the second guide column 55 of the third magnetic member 50 to move, so that the third magnetic member 50 moves along the second sliding slot 12 to approach the adjacent first magnetic member 25 to have the second magnetic attraction force. In this way, when the roller module 20 rotates, the second magnetic member 40, the third magnetic member 50 and the plurality of first magnetic members 25 can have a magnetic attraction force change to generate a paragraph touch feeling, achieving the advantages of avoiding mechanical errors, reducing operating noise and reducing friction loss.

[0115] Similarly, when the movable member 30 is swung from the second position (as shown in Figure 4 to the first position (as shown in Figure 5 ), the first inclined guide slot 31 and the second inclined guide slot 32 can also drive the second magnetic member 40 and the third magnetic member 50 to move away from the adjacent first magnetic member 25 along the first sliding slot 11 and the second sliding slot 12, respectively, so that the second magnetic member 40, the third magnetic member 50 and the plurality of first magnetic members 25 maintain a distance to have the first magnetic attraction force, so that the roller module 20 does not generate resistance when rotating. Figure 8 Figure 8 Figure 5

[0116] As shown in Figure 9 and Figure 10 ​​As shown, the second magnetic member 40 has at least one protrusion 46, and in this embodiment, the second magnetic member 40 has a plurality of protrusions 46, which are respectively arranged on opposite sides of the sliding block 41. The first sliding groove 11 of the base 10 has an inner surface 111, and the second magnetic member 40 is arranged such that each protrusion 46 contacts the inner surface 111 of the first sliding groove 11, and preferably, the second magnetic member 40 and the first sliding groove 11 form a point contact or a line contact instead of a surface contact. In this way, when the second magnetic member 40 slides relative to the first sliding groove 11, the frictional resistance can be greatly reduced, and the movement is more smooth. In addition, the third magnetic member 50 and the second sliding groove 12 can also have the same or similar arrangement, which is not repeated here. As shown in FIG. 6, the first sliding groove 11 and the second sliding groove 12 of the base 10 further have a buffer block 61, and when the movable member 30 is located at the first position or the second position (here, the first position), the second magnetic member 40 and the third magnetic member 50 respectively abut against the buffer block 61, so as to reduce the noise when the second magnetic member 40 and the third magnetic member 50 move. In some embodiments, the buffer block 61 can be a rubber block, a silica gel block or a foam.

[0117] As Figure 4 With Figure 8 As shown, the base 10 has a stop portion 13, and the stop portion 13 has a buffer member 60. The movable member 30 has a limiting portion 36, and when the movable member 30 is located at the first position or the second position, the limiting portion 36 abuts against the buffer member 60. In this embodiment, the stop portion 13 is a protrusion arranged on the first side surface 14, and when the movable member 30 is located at the second position (as shown in the position of FIG. 5B), the limiting portion 36 of the movable member 30 abuts against the buffer member 60, so as to reduce the noise when the movable member 30 moves. In some embodiments, the buffer member 60 can be a rubber block, a silica gel block or a foam. Figure 8 As

[0118] As shown in FIGS. 3A and 3B, the base 10 has a limiting column 16, and the first side plate 33 of the movable member 30 has an arc-shaped guide groove 331, and the limiting column 16 is slidably arranged in the arc-shaped guide groove 331. When the movable member 30 is located at the first position (as shown in the position of FIG. 3A), the limiting column 16 is located at one end of the arc-shaped guide groove 331, and when the movable member 30 is located at the second position (as shown in the position of FIG. 3B), the limiting column 16 is located at the other end of the arc-shaped guide groove 331. In this way, when the movable member 30 swings to the first position or the second position, the movable member 30 can be limited by the limiting column 16 and the arc-shaped guide groove 331, so as to avoid the movable member 30 from swinging beyond the expected range. Figure 4 Figure 5 As shown in FIGS. 3A and 3B, the base 10 has a limiting column 16, and the first side plate 33 of the movable member 30 has an arc-shaped guide groove 331, and the limiting column 16 is slidably arranged in the arc-shaped guide groove 331. When the movable member 30 is located at the first position (as shown in the position of FIG. 3A), the limiting column 16 is located at one end of the arc-shaped guide groove 331, and when the movable member 30 is located at the second position (as shown in the position of FIG. 3B), the limiting column 16 is located at the other end of the arc-shaped guide groove 331. In this way, when the movable member 30 swings to the first position or the second position, the movable member 30 can be limited by the limiting column 16 and the arc-shaped guide groove 331, so as to avoid the movable member 30 from swinging beyond the expected range. Figure 8 Figure 5 As Figure 8 As

[0119] As Figures 3 to 10 ​​As shown, the roller input device 1 may include a switching component 70, which is connected to the movable member 30. The user can drive the movable member 30 to swing relative to the base 10 to the first position or the second position through the switching component 70, so as to switch the operating feel of the roller module 20.

[0120] like Figures 3 to 10 As shown, the switching assembly 70 includes a sliding seat 71, a spring 72, and a torsion spring 73. The sliding seat 71 is movably connected to the base 10. In this embodiment, the base 10 has a guide groove 19, and the sliding seat 71 is slidably disposed in the guide groove 19. The sliding seat 71 has a top 711 and a bottom 712. The top 711 abuts against the end 301 of the movable member 30. The spring 72 is located inside the guide groove 19 and abuts against the base 10 and the bottom 712 of the sliding seat 71, so that the spring 72 can provide an upward force on the end 301 of the movable member 30 toward the top 711. One end of the torsion spring 73 is connected to the base 10, and the other end of the torsion spring 73 is connected to a position adjacent to the end 301 of the movable member 30, so that the torsion spring 73 can provide a downward force on the end 301 of the movable member 30 toward the bottom 712.

[0121] like Figures 3 to 10 As shown, the elastic force of spring 72 can be greater than the elastic force of torsion spring 73, making the upward force greater than the downward force. Therefore, as... Figure 5 As shown, under normal conditions, the sliding seat 71 of the switching component 70 can continuously abut against the end 301 of the movable member 30, so that the movable member 30 is maintained in the aforementioned first position (e.g., Figure 5 (as shown in the image). Figure 8 As shown, when the user presses the top 711 of the sliding seat 71, the sliding seat 71 slides down along the guide groove 19 and compresses the spring 72 to store elastic force. The downward force provided by the torsion spring 73 can drive the end 301 of the movable member 30 to move towards the bottom 712, so that the movable member 30 relative to the base 10 moves from the first position (as described above). Figure 5 Swing from the position shown to the second position (as indicated) Figure 8 (as shown in the position). Next, when the user releases the sliding seat 71, the elastic force stored in the spring 72 can drive the sliding seat 71 to slide upward along the guide groove 19. The sliding seat 71 can then drive the end 301 of the movable member 30 to move upward synchronously, so that the movable member 30 swings back from the second position to the first position.

[0122] like Figure 6As shown, in this embodiment, the slider 71 has multiple protruding ribs 713 around its periphery. There are four protruding ribs 713 located at the four corners of the slider 71. The slider 71 contacts the inner surface of the guide groove 19 with these protruding ribs 713, forming a line contact rather than a surface contact between the slider 71 and the guide groove 19. This significantly reduces frictional resistance and makes the movement smoother when the slider 71 slides relative to the guide groove 19.

[0123] like Figures 3 to 10 As shown, in this embodiment, the sliding seat 71 has an annular groove 75, and the annular groove 75 has a first recess 751 and a second recess 752, wherein the first recess 751 and the second recess 752 are located at different height positions. The switching component 70 includes a limiting member 74, which is a rod, and the limiting member 74 has a fixed end 741 and a movable end 742. The fixed end 741 is fixed to the base 10, and the movable end 742 is slidably disposed in the annular groove 75, that is, the movable end 742 of the limiting member 74 can slide and move along the annular groove 75.

[0124] like Figure 5 As shown, when the movable part 30 is in the first position, the movable end 742 of the limiting member 74 of the switching component 70 is limited within the first recess 751 of the annular groove 75, thereby limiting the movable part 30 and preventing resistance from being generated when the user operates the roller module 20 to rotate. Figure 8 As shown, when the user presses the top 711 of the sliding seat 71 to cause the movable member 30 relative to the base 10 from the aforementioned first position (as shown in the image), Figure 5 Swing from the position shown to the second position (as indicated) Figure 8 When the sliding seat 71 slides relative to the guide groove 19 (as shown in the image), the movable end 742 of the limiting member 74 can slide along the annular groove 75 and be confined within the second recess 752, so that the movable member 30 can also be confined in the second position, and the user can experience a tactile feedback when operating the roller module 20 to rotate. Then, when the user presses the top 711 of the sliding seat 71 again to move the movable member 30 relative to the base 10 from the second position (as shown in the image), the movable member 30 can slide relative to the base 10 from the second position (as shown in the image). Figure 8 The position shown) swings to the first position (as indicated). Figure 5 When the sliding seat 71 slides relative to the guide groove 19 at the position shown, the movable end 742 of the limiting member 74 will slide along the annular groove 75 again and be limited in the first recess 751, so that the movable member 30 can be limited in the first position, and achieve the operating feel of freely switching the roller module 20.

[0125] Figure 11 This is an exploded perspective view of the second embodiment of the roller input device of the present invention. Figure 12This is a side view of the movable member in the first position of the second embodiment of the roller input device of the present invention. Figure 13 for Figure 12 A sectional view along line segment 13-13. Figure 14 This is a side view of the movable member in the second position of the second embodiment of the roller input device of the present invention. Figure 15 for Figure 14 A sectional view along line segment 15-15. (See example.) Figures 11 to 15 As shown, the difference between this embodiment and the first embodiment described above is at least that the roller body 21a of the roller input device 1a in this embodiment has a plurality of recesses 23 on one side. The plurality of recesses 23 are arranged in a ring and are spaced apart from each other. A plurality of first magnetic elements 25a are respectively fixed in the plurality of recesses 23. In addition, the first groove 11 and the second groove 12 of the base 10 are located outside the roller body 21a, and the second magnetic element 40a and the third magnetic element 50a are integrally formed. For example, the roller body 21a may be a plastic body, each of the first magnetic elements 25a may be a magnet, and the second magnetic element 40a and the third magnetic element 50a may be blocks made of magnetically conductive material.

[0126] like Figure 12 and Figure 13 As shown, with the above structural arrangement, when the movable part 30 swings relative to the base 10 to the first position (e.g., Figure 12 When the position shown is such that the second magnetic element 40a and the adjacent first magnetic element 25a maintain a distance and thus have the aforementioned first magnetic attraction, and the third magnetic element 50a and the adjacent first magnetic element 25a also maintain a distance and thus have the aforementioned first magnetic attraction, so that the roller module 20a will not generate resistance during rotation. Figure 14 and Figure 15 As shown, when the movable part 30 moves from the first position mentioned above (e.g.) Figure 12 Swing from the position shown to the second position (as indicated) Figure 14 When the position shown is reached, the second magnetic element 40a and the third magnetic element 50a move outside the roller module 20a to approach the first magnetic element 25a located outside the roller body 21a and generate the second magnetic attraction force mentioned above, so that the roller module 20a can generate a segmented tactile sensation during rotation.
