Description

Roller mouse

Technical Field

The present invention relates to a roller mouse, and more particularly, to a roller mouse with different paragraph sense patterns.

Background

Computer systems are important tools for modern people, and their uses include text processing, video playback, drawing, programming, and so on. Generally, a computer system is connected to a mouse and a keyboard, so that a user can operate the computer system by operating the mouse and the keyboard. Among them, the roller mouse is the most popular input device because it can be held by the palm of the user to control the movement of the mouse cursor and conforms to the operation habit of most users.

The structure of the wheel mouse will be described next. Please refer to fig. 1, which is a schematic diagram of an appearance structure of a conventional roller mouse, and is also a roller mouse disclosed in U.S. patent No. 7733328. The wheel mouse 10 includes a housing 101, a wheel module 105, control buttons 110, a detector (not shown), and an encoder (not shown). The detector and the encoder are configured to detect movement of the housing 101 relative to a work surface (e.g., a desktop on which a mouse wheel is placed), and output a corresponding signal to a computer system to control a movement track of a mouse cursor.

Please refer to fig. 2, which is a schematic structural diagram of a wheel module of a conventional wheel mouse. The roller module 105 includes a roller 106, a bracket 107, a pivoting arm 108 and a driving motor 104, wherein the roller 106 is disposed in the bracket 107, and can be rotated by a user to generate a corresponding roller rotation amount, so that the computer system executes a specific control command according to the roller rotation amount. The specific control command is, for example, scrolling of a computer window, zooming of a picture, or adjusting of volume, etc.

The inner edge of the roller 106 has a corrugated surface 1061, and when the pivot arm 108 contacts the corrugated surface 1061 according to the driving of the driving motor 104, the roller 106 will have a multi-turn feeling each time it rotates, which provides a function similar to a scale, so that the executed specific control command can generate a difference in execution degree according to the turn feeling. For example, when the scroll wheel 106 is rotated and each time a paragraph sense is generated, the computer system scrolls the computer window three lines.

Conversely, when the pivot arm 108 is moved away from the corrugated surface 1061 by the driving motor 104 and the roller 106 is moved by the user, the rotation of the roller 106 is not affected by the contact between the pivot arm 108 and the corrugated surface 1061, i.e., the roller 106 is rotated in a smooth and non-paragraph manner, so that the maximum command can be directly executed by the specific control command. For example, when a user wants to scroll the computer window from the top to the bottom, the user does not need to repeatedly dial the roller 106 to rotate the computer window, and only needs to dial the roller 106 once, the computer window can be continuously scrolled until the computer window is scrolled to a position required by the user, and then the rotation of the roller 106 is stopped.

Please refer to fig. 3, which is an exploded view of a wheel module of a conventional wheel mouse. Fig. 3 shows a trigger switch 109 disposed below the bracket 107, when a user touches the roller 106, the roller 106 drives the bracket 107 to move downward as shown in the vertical direction D, so that the bracket 107 touches the trigger switch 109, the trigger switch 109 activates the driving motor 104, and the driving motor 104 drives the pivoting arm 108, so that the pivoting arm 108 contacts the corrugated surface 1061 of the contact roller 106 or the pivoting arm 108 does not contact the corrugated surface 1061 of the contact roller 106.

In summary, the conventional wheel mouse 10 can provide two distinct sensing modes according to whether the pivot arm 108 thereof is in contact with the corrugated surface 1061 thereof, and the switching of the two distinct sensing modes is performed by touching the wheel 106. Among them, a wheel mouse having two distinct modes has been proposed for many years, and how to provide a good switching manner and reduce the mouse cost has become a current subject of manufacturers.

It is to be understood that elements not specifically shown in the drawings or described in the specification are in a form known to those skilled in the art. Various changes and modifications can be made by one skilled in the art in light of the above teachings.

Referring to fig. 4 and 5, fig. 4 is a partially exploded view of the wheel mouse according to the first preferred embodiment of the present invention, and fig. 5 is another partially exploded view of the wheel mouse according to the first preferred embodiment of the present invention. The wheel mouse 2 of the present invention comprises a housing 21, a wheel module 22, a swing component 23 and a switch button 24, wherein the housing 21 comprises a first housing opening 211 and a second housing opening 212, wherein the first housing opening 211 corresponds to the wheel module 22, and the second housing opening 212 corresponds to the switch button 24. The roller module 22 includes a roller 221, a roller swing seat 222, a fixing column 223, an elastic element 224 and a signal generating module 225, and the roller 221 includes a roller body 2211, a rotating shaft 2212 and a fence structure 2213.

The roller module 22 is disposed in the housing 21, and a roller 221 of the roller module 22 partially passes through the first housing opening 211 and is exposed outside the housing 21, and can be rotated by a user. In the roller 221, the roller body 2111 passes through the first housing opening 211 and partially exposes out of the housing 21, the rotating shaft 2212 is disposed in the roller body 2111, and the fence structure 2213 is disposed between the roller body 2111 and the rotating shaft 2212. In the preferred embodiment, the rotating shaft 2212 and the fence 2213 are integrally formed with the roller body 2111, which is for illustration purposes only and not limited thereto.

In fig. 4 and 5, the swing assembly 23 is fixed on the roller module 22 and close to the roller 221, and can swing relative to the roller module 22 to close to the roller 221 and contact the fence structure 2213, or to move away from the roller 221 and not contact the fence structure 2213. The switch button 24 passes through the second housing opening 212 and is partially exposed outside the housing 21, and can move relative to the housing 21 to drive the swing component 23 to swing. When the switch button 24 is located at the first position P1, the swing assembly 23 is not pressed by the switch button 24 and is in a state of contacting the fence structure 2213, so that the wheel module 22 is in the first paragraph feeling mode. When the switch button 24 is moved to the second position P2, the swing element 23 is pushed by the switch button 24 to swing away from the roller 221 without contacting the fence 2213, so that the roller module 22 is in the second paragraph feeling mode.

The structure of the other elements of the roller module 22 will be described next. Referring to fig. 4, 5 and 6, fig. 6 is a partial structural schematic view of the wheel mouse in the first paragraph sensing mode according to the first preferred embodiment of the present invention. In the roller module 22, the roller swing seat 222 is disposed in the housing 21 and can swing relative to the housing 21, and can receive the roller 221 therein. The rotating shaft 2212 can rotatably pass through the first openings 2222 of the roller swing seat 222, and fix the roller 221 on the roller swing seat 222. In detail, the roller swing seat 222 includes a seat body 2221, a plurality of first openings 2222 and a plurality of second openings 2223, the plurality of first openings 2222 are located on the seat body 2221, and the rotating shaft 2212 can pass through the first openings, and the roller 221 is fixed in the seat body 2221. The second openings 2223 are located on the side surfaces of the housing 2221, and the second openings 2223 correspond to the signal generating module 225, so that the signal generating module 225 can detect the rotation of the roller 221 through the second openings 2223.

On the other hand, the fixing post 223 is disposed on the seat 2221 of the roller swing seat 222, and can pass through the swing component 2 to fix the swing component 23 on the roller swing seat 222. The elastic element 224 is sleeved on the fixing column 223 and contacts the swinging component 23, and functions to apply an elastic force to the swinging component 23 when the swinging component 23 is not pressed by the switching key 24, so that the swinging component 23 contacts the fence structure 2213 of the roller 221. The signal generating module 225 is disposed adjacent to the roller swing seat 222 and functions to detect the rotation of the roller 221 and output a corresponding rotation signal. In the preferred embodiment, the elastic element 224 is a torsion spring, and the signal generating module 225 includes an optical transmitter 2251 and an optical receiver 2252. Wherein the light emitter 2251 is located on the first side of the roller swing seat 222 and functions to generate a light beam and to pass the light beam through the barrier structure 2213. The light receiver 2252 is located on the second side of the roller wobble seat 222 and functions to receive the light beam passing through the barrier structure 2213 and generate a corresponding rotation signal.

Next, the structure of the swing assembly 23 will be explained. Referring to fig. 5 and 6, the swing assembly 23 includes a body 231, a first contact portion 232 and a second contact portion 233, and the body 231 has a fixing hole 2311, so that the fixing post 223 passes through the fixing hole 2311, thereby fixing the body 231 on the fixing post 223. The first contact portion 232 is disposed on the first end of the body 231 and close to the roller 221, and can contact the fence structure 2213 when the swing assembly 23 approaches the roller 221. The second contact portion 233 is disposed on the second end of the main body 231, and can be pushed by the switch button 24 to make the swing component 23 swing relative to the roller swing seat 222. In the preferred embodiment, the first contact portion 232 and the second contact portion 233 are integrally formed with the body 231, which is only for illustration purpose, but not limited thereto. In another preferred embodiment, the first contact portion and the second contact portion can be fixed on the body in any manner.

The operation of the wheel mouse 2 of the present invention will be described. Referring to fig. 6 and 7, fig. 7 is another partial structural diagram of the wheel mouse in the second paragraph feeling mode in the first preferred embodiment of the present invention. When the user wants the wheel mouse 2 to provide the falling feeling, the user can toggle the switch button 24 to the first position P1, so that the switch button 24 does not abut against the second contact portion 233 of the swing element 23, and the swing element 23 is under the elastic force of the elastic element 224 to make the first contact portion 232 contact with the fence structure 2213. At this time, the roller module 22 enters the first step feeling mode, as shown in fig. 6. When the user pulls the roller 221, the user feels a sense of falling due to the collision of the swing assembly 23 with the barrier structure 2213 because the swing assembly 23 is in contact with the barrier structure 2213.

On the contrary, when the user does not want the wheel mouse 2 to provide the paragraph feeling, the user can toggle the switch button 24 to the second position P2, so that the switch button 24 pushes against the second contact portion 233, and the swing component 23 swings away from the fence structure 2213. Thus, the first contact portion 232 of the swing assembly 23 is away from the roller 221 without contacting the barrier structure 2213. At this time, the roller module 22 enters the second step feeling mode, i.e. when the user rotates the roller 221, there is no step feeling, as shown in fig. 7.

In addition, the invention also provides another preferred embodiment with different functions from the functions described above. Referring to fig. 8 and 9, fig. 8 is an exploded view of a portion of a mouse wheel according to a second preferred embodiment of the present invention, and fig. 9 is a schematic view of a portion of a mouse wheel according to a second preferred embodiment of the present invention. The roller mouse 3 of the present invention includes a housing 31, a roller module 32, a swing component 33 and a switching module 34, wherein the roller module 32 includes a roller 321, a roller swing seat 322, a fixing post (not shown), an elastic element 324 and a signal generating module 325, and the roller 321 includes a roller body 3211, a rotating shaft 3212 and a fence structure 3213. Most of the structure and operation of the preferred embodiment are substantially the same as those of the first preferred embodiment, and thus are not described again. The two differences are mainly two, firstly, the switching module 34 is adopted in the preferred embodiment to swing the swing component 33. Second, a signal generating module 325 for generating a wheel rotation signal is provided.

First, the structure of the switching module 34 will be described. The switching module 34 is disposed in the housing 31 and contacts the swinging component 33, and can be driven by, for example, battery power to drive the swinging component 33 to swing. When the switching module 34 is not driven, the swing assembly 33 contacts the barrier structure 3213, so that the roller module 32 is in the first paragraph feeling mode. On the contrary, when the switching module 34 is driven to abut against the swing assembly 33, the swing assembly 33 is far away from the roller 321 and does not contact with the fence structure 3214, so that the roller module 32 is in the second paragraph feeling mode.

In fig. 8, the switching module 34 includes a power element 341 and a cam structure 342. The power element 341 is disposed in the housing 31 and functions to be driven by electric power to provide a rotational force. The cam structure 342 is connected to the power element 341, which is rotatable according to a rotational force. When the cam structure 342 rotates to the first angle, the cam structure is located at a position not abutting against the swing assembly 33, so that the swing assembly 33 is forced by the elastic element 324 to contact the fence structure 3213, and the roller module 32 is in the first section sensing mode. On the contrary, when the cam structure 342 rotates to the second angle, the cam structure 342 abuts against the swing assembly 33, so that the swing assembly 33 swings away from the fence structure 3213, and the roller module 32 is in the second section sensing mode.

The structure of the signal generating module 325 for generating the wheel signal according to the present embodiment will be described next. Referring to fig. 8 and 9, the signal generating module 325 includes a magnetic element 3251, a circuit board 3252 and a hall sensor 3253. The magnetic element 3251 is disposed on the rotating shaft 3212 and can rotate synchronously with the rotating shaft 3212, and the circuit board 3252 is disposed on a side surface of the roller swing seat 322. The hall sensor 3253 is disposed on the circuit board 3252 and close to the magnetic element 3251, and functions to detect a change in a magnetic field of the rotating magnetic element 3251 and generate a corresponding rotation signal.

Second, first, according to the configuration of the switch module 34 disposed in the housing 31, the housing 31 has only a single housing opening 311 corresponding to the roller module 32, but not the second housing opening 212 of the aforementioned preferred embodiment. Second, according to the structure of the signal generating module 325, the roller swing seat 322 only has a plurality of openings 3222 corresponding to the rotation shaft 3212, but is not provided with the plurality of second openings 2223 of the foregoing preferred embodiment.

According to the above, the wheel mouse of the present invention utilizes a simple structure to switch between different paragraph sense modes, that is, the paragraph sense modes can be switched by the linkage between the simple swing component and the switch button (or the switch module). Therefore, the simple structure not only can provide a stable switching mode, but also can reduce the cost of the mouse so as to solve the problems of the prior art.

The above-mentioned embodiments are merely preferred embodiments of the present invention, which are not intended to limit the scope of the present invention, and therefore, all equivalent changes and modifications that do not depart from the spirit of the present invention are intended to be included within the scope of the present invention.
