Description

Mouse device

Technical Field

The present invention relates to an input device, and more particularly, to an application mouse device.

Background

The mouse is used for controlling a cursor on a computer screen and operating the computer. After the first mouse around the world was manufactured from the united states in 1968, the mouse has become an integral part of computer equipment, whether it be text processing, game contests, industrial drawing, design drawing or media production.

Generally, an operation interface of the mouse includes: left and right keys and a wheel. In order to improve the convenience and comfort of the mouse roller during operation, in the prior art, for example, in taiwan patent publication No. I448928, a roller module of an input device is proposed, in which one to two different toothed surfaces are disposed in a groove or a hollow groove of the roller, and then one of the toothed surfaces is touched by a swing arm, so that different paragraph sensations are generated when the roller rotates; or, as in taiwan patent publication No. M498914, a shuttle roller module of a mouse is proposed, in which a toothed portion and a resisting rod are disposed in the roller device, and the resisting rod is elastically pressed against the toothed portion by a torsion spring, so that a user can operate a button member linked with the resisting rod to switch the roller between a fast shuttle mode and a normal roller mode.

After long-time use, the contact interference method may wear the roller module, so that the roller module cannot generate corresponding paragraph sense when rotating.

Therefore, how to provide a mouse device capable of rapidly switching the rotation mode of the roller module and reducing the wear of the roller module is a technical problem to be solved by the invention.

This invention may, however, be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, such embodiments are provided to enable those skilled in the art to more fully and fully convey the scope of the invention.

First, please refer to fig. 1A, fig. 1B and fig. 1C. FIG. 1A is a schematic perspective view of a roller control mechanism according to the present invention; FIG. 1B is an exploded perspective view of the roller control mechanism according to the present invention; fig. 1C is a cross-sectional view of a coil magnet according to the present invention. The roller control mechanism RS includes: the device comprises a support base 10, a roller module 20, a magnetic force module 30 and a rotation speed detection unit 40.

The support base 10 has a first support portion 11, a second support portion 12 and a fixing portion 13, wherein the roller module 20 and the magnetic module 30 are respectively mounted on the first support portion 11 and the second support portion 12.

Next, please refer to fig. 1B. The first supporting portion 11 has a recess 111 and two pivot holes 112 disposed opposite to each other on a sidewall of the recess 111.

The magnetic module 30 includes: a magnetic element 31, a coil magnet 32 and two magnetic conductors 33, 34. The magnetic element 31 is a strong magnet having an N pole end 311 and an S pole end 312. The coil magnet 32 includes: the coil base 321, the weak magnetic metal magnet 322 (as shown in fig. 1C), and the plurality of coils 323, wherein the weak magnetic metal magnet 322 is an alnico magnet and is disposed in the coil base 321, and the weak magnetic metal magnet 322 has a third end 3221 and a fourth end 3222 opposite to each other. On the other hand, the coil 323 is wound around the surface of the coil base 321. The two magnetic conductive elements 33 and 34 are silicon steel plates, which have opposite first ends 331 and 341 and second ends 332 and 342, respectively, wherein the first ends 331 and 341 have claw structures 3311 and 3411, respectively.

The magnetic element 31 is disposed between the two magnetic conductive members 33, 34 and adjacent to the first ends 331, 341; the coil magnet 32 is disposed between the second ends 332, 342 of the two magnetic conductive members 33, 34. In the present embodiment, the two magnetic conductive members 33, 34 are respectively disposed in the upper communication recess 1213 and the lower communication recess 1214, and the first ends 331, 341 can penetrate the mounting groove 121 and approach the ring gear structure 221 on the side edge of the metal ratchet wheel 22; the magnetic element 31 is disposed in the first recess 1211, and the N-pole end 311 and the S-pole end 312 are respectively abutted against the magnetic conductive members 33, 34; the coil magnet 32 is disposed in the second recess 1212, and the third end 3221 and the fourth end 3222 of the weak magnetic metal magnet 322 are respectively abutted against the magnetic conductive members 33, 34.

In this embodiment, the fixing portion 13 abuts the first supporting portion 11, and the fixing portion 13 has a locking hole 131, so that a locking member, such as a screw (not shown), can be inserted into the locking hole 131 to screw the fixing portion 13 onto a housing (not shown) or a main circuit board (not shown) of the mouse device.

Referring to fig. 2, fig. 2 is a system block diagram of a mouse device according to the present invention. The mouse device 1 has a control unit 90, and the control unit 90 is electrically connected to the magnetic module 30 and the rotation speed detecting unit 40 of the control mechanism RS (shown in fig. 1B), respectively. In this embodiment, the control unit 90 is disposed on a main circuit board (not shown in the drawings) of the mouse device 1, and may be: flash Memory (Flash Memory), electrically erasable and rewritable read-Only Memory (EEPROM) or programmable read-Only Memory (Programmable read-Only Memory, PROM), and the control unit 90 has a firmware 91, and the firmware 91 includes a predetermined rotation speed threshold 911. The control unit 90 receives the rotational speed information of the roller body 21 (shown in fig. 1B) detected by the rotational speed detecting unit 40, and drives the coil magnet 32 (shown in fig. 1B) in the magnetic module 30 with direct current in different directions according to the rotational speed information, so that the roller module 20 can switch between different rotational modes.

Referring to fig. 3, fig. 3 is a schematic side view illustrating a rotation mode of the roller control mechanism according to the present invention. In fig. 3, the control unit 90 drives the coil magnet 32 with a first direction current C1, and when the first direction current C1 passes through the coil 323, the third end 3221 of the weak magnetic metal magnet 322 is N-pole according to ampere right hand rule; the fourth end 3222 is an S-pole. At this time, the magnetic element 31 and the coil magnet 32 are opposite to each other in the same polarity to form a repulsive state, that is: the N pole end 311 of the magnetic element 31 is opposite to the third end 3221 which is an N pole; the S-pole end 312 of the magnetic element 31 is opposite to the fourth end 3222 which is an S-pole. At this time, the magnetic lines ML1 emitted from the N pole 311 of the magnetic element 31 and the magnetic lines ML2 emitted from the third end 3221 of the weak magnetic metal magnet 322 are mutually repelled, so that the magnetic field formed by the magnetic element 31 is offset towards the first ends 331 and 341 of the two magnetic conductive elements 33 and 34, and the first ends 331 and 341 of the magnetic conductive elements 33 and 34 generate magnetic attraction force, so that the first ends 331 and 341 can attract the metal ratchet 22 to slow down the rotation speed of the metal ratchet 22.

Please continue to refer to fig. 3. Compared to the recess 2212 on the ring gear 221, the gap between the claw structures 3311, 3411 of the first ends 331, 341 of the magnetic conductive elements 33, 34 and the protrusion 2211 on the ring gear 221 is smaller, so that when the metal ratchet 22 rotates, a larger magnetic attraction force is generated at the moment when the claw structures 3311, 3411 are opposite to the protrusion 2211, and the rotation speed of the roller body 21 can be instantaneously slowed down, so that the roller body 21 generates a sectional sense during rotation. In some possible embodiments, the roller body 21 may be rotated to create multiple paragraphs by adjusting the spacing between the two protrusions 2211 (e.g., reducing or enlarging the size of the recess 2212). Alternatively, the coil magnet 32 may be driven by the current C1 with different intensities in the first direction, so that the coil magnet 32 forms magnetic fields with different intensities, and the first ends 331, 341 of the magnetic conductive elements 33, 34 generate magnetic attraction with different intensities, so that the roller body 21 generates different degrees of light and heavy section sensations during rotation.

On the other hand, the control unit 90 may also control to stop the direct current from passing through the coil magnet 32. The magnetic field of the magnetic element 31 is not shifted, so that the first ends 331, 341 of the magnetic conductive elements 33, 34 can only generate weak magnetic attraction force, and the roller body 21 generates less obvious sectional sense when rotating.

Referring to fig. 4, fig. 4 is a schematic side view illustrating another rotation mode of the roller control mechanism according to the present invention. In fig. 4, the control unit 90 drives the coil magnet 32 with a second direction current C2, and when the second direction current C2 passes through the coil 323, the third end 3221 of the weak magnetic metal magnet 322 is S-pole according to ampere right hand rule; the fourth end 3222 is an N-pole. At this time, the magnetic element 31 and the coil magnet 32 are opposite to each other in opposite poles to form a attracted state, namely: the N pole end 311 of the magnetic element 31 is opposite to the third end 3221 which is an S pole; the S-pole end 312 of the magnetic element 31 is opposite to the fourth end 3221 which is an N-pole. At this time, the magnetic force line ML1 emitted from the N pole 311 of the magnetic element 31 enters the third end 3221 of the S pole of the weak magnetic metal magnet 322; the magnetic force line ML2 emitted from the fourth end 3222 of the N pole of the weak magnetic metal magnet 322 enters the S pole end 312 of the magnetic element 31, so that the magnetic element 31 and the coil magnet 32 form a closed magnetic field, and the magnetic attraction of the first ends 331, 341 of the magnetic conductive elements 33, 34 is weakened to be unable to attract the metal ratchet 22, so that the roller body 21 can rotate smoothly and no section sense is generated.

Please continue to refer to fig. 2, 3 and 4. In fig. 2, the rotation speed detecting unit 40 transmits the detected rotation speed information of the roller body 21 back to the control unit 90, and the control unit 90 determines the rotation mode according to the rotation speed of the roller body 21 and the rotation speed threshold 911. In the present embodiment, the rotation speed threshold 911 is approximately equal to 2.83rps (rotations per second), and is defined as the shuttle mode when the rotation speed of the roller body 21 is higher than the rotation speed threshold 911; when the rotational speed of the roller body 21 is lower than the rotational speed threshold 911, it is defined as a general mode.

For example, when the user rapidly dials the roller body 21 to make the rotation speed of the roller body 21 higher than the preset rotation speed threshold 911, it indicates that the user needs a shuttle mode capable of rapidly rotating the roller body 21, so as to rapidly browse a plurality of pages of the display. At this time, the control unit 90 drives the coil magnet 32 with the current C2 in the second direction, so that the magnetic attraction force of the first ends 331, 341 of the magnetic conductive elements 33, 34 is weakened, and the roller body 21 can smoothly rotate without generating a feeling of a break.

In contrast, in the normal mode, that is, when the rotational speed of the roller body 21 is lower than the rotational speed threshold 911, the control unit 90 drives the coil magnet 32 with the current C1 in the first direction, so that the first ends 331 and 341 of the magnetic conductive elements 33 and 34 generate magnetic attraction force, and the roller body 21 rotates to generate a paragraph effect. It should be noted that the value of the rotation speed threshold 911 can be adjusted according to the size or the usage requirement of the roller body 21, and in some possible embodiments, multiple sets of rotation speed thresholds can be set, not limited to the embodiment presented in the present embodiment.

The mouse device provided by the invention has the beneficial effects that the magnetic element with the fixed magnetic field direction and the coil magnet with the switchable magnetic field direction can be utilized to adjust the rotation mode of the roller module in a non-contact mode, so that the roller body of the roller module generates no paragraph sense or multiple paragraph sense when rotating. Compared with the traditional design of adjusting the rotation mode of the roller by a contact type interference method, the non-contact type magnetic force module not only can switch the rotation mode of the roller more quickly, but also can effectively reduce the loss of the roller module; therefore, the invention is an creation with great industrial value.

The invention is modified as desired by those skilled in the art, but is not to be construed as limited by the appended claims.
