Description

Wheel Mouse

Technical Field

The invention relates to a roller mouse, in particular to a roller mouse with different paragraph sense modes.

Background technique

Computer systems are important tools for modern people, and their uses include text processing, video and audio playback, drawing, program writing, etc. Generally speaking, a computer system is connected to a mouse and a keyboard, so that users can operate the computer system by operating a scroll wheel mouse and the keyboard. Among them, since the scroll wheel mouse can be held by the user's palm to control the movement of the mouse cursor and conforms to the operating habits of most users, the scroll wheel mouse has become the most common input device.

Next, the structure of the wheel mouse is described. Please refer to FIG. 1, which is a schematic diagram of the appearance structure of a known wheel mouse, and is also the wheel mouse proposed in the announcement of U.S. Patent No. 7733328. The wheel mouse 10 includes a housing 101, a wheel module 105, a control button 110, a detector (not shown in the figure), and an encoder (not shown in the figure). The function of the detector and the encoder is to detect the movement of the housing 101 relative to the working surface (for example, the desktop on which the wheel mouse is placed), and output a corresponding signal to the computer system to control the movement trajectory of the mouse cursor.

As for the structure of the wheel module 105, please refer to FIG. 2, which is a schematic diagram of the structure of the wheel module of a conventional wheel mouse. The wheel module 105 includes a wheel 106, a bracket 107, a pivot arm 108, and a drive motor 104. The wheel 106 is disposed in the bracket 107, and can be turned by the user to rotate and generate a corresponding amount of wheel rotation, so that the computer system executes a specific control instruction according to the amount of wheel rotation. The specific control instruction is, for example, scrolling of a computer window, zooming of an image, or adjustment of the volume, etc.

The inner edge of the roller 106 has a corrugated surface 1061. When the pivot arm 108 contacts the corrugated surface 1061 according to the drive of the drive motor 104, the roller 106 will present multiple paragraphs every time it rotates. The paragraphs can provide a similar function to a scale, so that the specific control instructions executed can have different execution degrees according to the paragraphs. For example, when the roller 106 is rotated and each time a paragraph is generated, the computer system scrolls the computer window by three lines.

On the contrary, when the pivot arm 108 leaves the corrugated surface 1061 according to the driving of the driving motor 104, and the roller 106 is turned by the user, since the pivot arm 108 is not in contact with the corrugated surface 1061, the rotation of the roller 106 is not affected by it and will continue for a period of time, that is, the roller 106 rotates in a smooth and seamless manner, so that the executed specific control command can directly execute the maximum degree of instruction. For example, when the user wants to scroll his computer window from the top to the bottom, he does not need to repeatedly turn the roller 106 to make it rotate. He only needs to turn the roller 106 once, and the computer window can continue to scroll until the computer window scrolls to the position required by the user and then stops the rotation of the roller 106.

Please refer to FIG3 , which is a schematic diagram of the structure of the conventional scroll wheel module of the scroll wheel mouse. FIG3 shows a trigger switch 109, which is disposed below the bracket 107. When the user presses the scroll wheel 106, the scroll wheel 106 drives the bracket 107 to move downward in the vertical direction D, so that the bracket 107 presses the trigger switch 109, thereby the trigger switch 109 starts the drive motor 104, and the drive motor 104 drives the pivot arm 108, so that the pivot arm 108 contacts the corrugated surface 1061 of the contact scroll wheel 106 or does not contact the corrugated surface 1061 of the contact scroll wheel 106.

In general, the conventional wheel mouse 10 can provide two step sense modes according to whether its pivot arm 108 contacts its corrugated surface 1061, and the switching between the two step sense modes is performed by pressing the wheel 106. Among them, the wheel mouse with two step sense modes has been launched for many years, and how to provide a good switching method and reduce the cost of the mouse has become a current issue for various manufacturers.

Summary of the invention

The object of the present invention is to provide a scroll wheel mouse which can provide two paragraph sense modes and reduce the cost of the mouse.

In a preferred embodiment, the present invention provides a scroll wheel mouse, comprising a housing, a scroll wheel module, a swinging assembly and a switch button. The scroll wheel module is disposed in the housing, the scroll wheel module comprises a scroll wheel, the scroll wheel is used to be turned and rotated, and the scroll wheel comprises a scroll wheel body, a rotating shaft and a fence structure. The scroll wheel body is partially exposed outside the housing, the rotating shaft is disposed inside the scroll wheel body, and the fence structure is located between the scroll wheel body and the rotating shaft. The swinging assembly is fixed to the scroll wheel module and is close to the scroll wheel, and is used to swing relative to the scroll wheel module and approach the scroll wheel and contact the fence structure, or to move away from the scroll wheel and not contact the fence structure. The switch button is partially exposed outside the housing, and is used to move relative to the housing to drive the swinging assembly to swing. Among them, when the switch button is moved to a first position, the swing component is not pushed by the switch button and contacts the fence structure, so that the roller module is in a first paragraph sense mode; and when the switch button is moved to a second position, the swing component is pushed by the switch button away from the roller and does not contact the fence structure, so that the roller module is in a second paragraph sense mode.

In a preferred embodiment, the present invention also provides a scroll wheel mouse, comprising a housing, a scroll wheel module, a swinging assembly and a switching module. The switching module comprises a power source and a cam structure. The scroll wheel module is disposed in the housing, and the scroll wheel module comprises a scroll wheel, which is used to be turned and rotated, and the scroll wheel comprises a scroll wheel body, a rotating shaft and a fence structure. The scroll wheel body is partially exposed outside the housing, the rotating shaft is disposed in the scroll wheel body, and the fence structure is located between the scroll wheel body and the rotating shaft. The swinging assembly is disposed on the scroll wheel module and close to the scroll wheel, and is used to swing relative to the scroll wheel module and approach the scroll wheel and contact the fence structure, or to move away from the scroll wheel and not contact the fence structure. The switching module is disposed in the housing, and is used to be driven to drive the swinging assembly to swing. When the cam structure rotates to a first angle, the cam structure does not abut the swing component, so the swing component contacts the fence structure, so that the roller module is in the first paragraph sense mode; and when the cam structure rotates to a second angle, the cam structure abuts the swing component, so that the swing component does not contact the fence structure, and the roller module is in the second paragraph sense mode.

In general, the scroll wheel mouse of the present invention uses a simple structure to switch between different paragraph sense modes, that is, the paragraph sense mode can be switched through the linkage between a simple swing component and a switch button (or switch module). Therefore, the simple structure can not only provide a stable switching method, but also reduce the cost of the mouse, thereby solving the problems of the prior art.

In view of the problems caused by the known technology, the present invention provides a wheel mouse that can solve the problems of the known technology. The embodiments of the present invention will be further explained below with reference to the relevant drawings. In the drawings, the shapes and sizes may be exaggerated for simplicity and convenience. It is understood that the components not specifically shown in the drawings or described in the specification are forms known to those skilled in the art. A person skilled in the art can make various changes and modifications based on the content of the present invention.

Please refer to FIG. 4 and FIG. 5 simultaneously. FIG. 4 is a partial structural exploded diagram of the scroll wheel mouse of the present invention in the first preferred embodiment, and FIG. 5 is another partial structural exploded diagram of the scroll wheel mouse of the present invention in the first preferred embodiment. The scroll wheel mouse 2 of the present invention comprises a housing 21, a scroll wheel module 22, a swing assembly 23 and a switch button 24, and the housing 21 comprises a first housing opening 211 and a second housing opening 212, wherein the first housing opening 211 corresponds to the scroll wheel module 22, and the second housing opening 212 corresponds to the switch button 24. The scroll wheel module 22 comprises a scroll wheel 221, a scroll wheel swing seat 222, a fixing column 223, an elastic element 224 and a signal generating module 225, and the scroll wheel 221 comprises a scroll wheel body 2211, a rotating shaft 2212 and a fence structure 2213.

The roller module 22 is disposed in the housing 21, and the 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 turned by the user to rotate. In the roller 221, the roller body 2211 passes through the first housing opening 211 and is partially exposed outside the housing 21, the rotating shaft 2212 is disposed in the roller body 2211, and the fence structure 2213 is located between the roller body 2211 and the rotating shaft 2212. In this preferred embodiment, the rotating shaft 2212 and the fence structure 2213 are integrally formed with the roller body 2211, which is only for illustrative purposes and is not limited thereto.

In FIG. 4 and FIG. 5 , the swing assembly 23 is fixed on the roller module 22 and close to the roller 221. It can swing relative to the roller module 22 and approach the roller 221 and contact the fence structure 2213, or it can be away from the roller 221 and not contact the fence structure 2213. The switch button 24 passes through the second shell opening 212 and is partially exposed outside the shell 21. It can move relative to the shell 21 to drive the swing assembly 23 to swing. Among them, 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 roller module 22 is in the first paragraph sense mode. When the switch button 24 is moved to the second position P2, the swing assembly 23 is pressed by the switch button 24 and swings away from the roller 221 and does not contact the fence structure 2213, so that the roller module 22 is in the second paragraph sense mode.

Next, the structures of other components of the scroll wheel module 22 are described. Please refer to Figures 4, 5 and 6 at the same time. Figure 6 is a schematic diagram of the partial structure of the scroll wheel mouse of the present invention in the first preferred embodiment in the first paragraph sense mode. In the scroll wheel module 22, the scroll wheel swing seat 222 is arranged in the shell 21 and can swing relative to the shell 21, and it can accommodate the scroll wheel 221 therein. Among them, the rotating shaft 2212 rotatably passes through the multiple first openings 2222 of the scroll wheel swing seat 222, and the scroll wheel 221 is fixed on the scroll wheel swing seat 222. In detail, the scroll wheel swing seat 222 includes a seat body 2221, a multiple first openings 2222 and a multiple second openings 2223. The multiple first openings 2222 are located on the seat body 2221, which can allow the rotating shaft 2212 to pass through, and the scroll wheel 221 is fixed in the seat body 2221. The plurality of second openings 2223 are located on the side surfaces of the base 2221 , and the plurality of 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 plurality of second openings 2223 .

On the other hand, the fixing column 223 is disposed on the base 2221 of the roller swing seat 222, and can pass through the swing assembly 23 to fix the swing assembly 23 on the roller swing seat 222. The elastic element 224 is sleeved on the fixing column 223 and contacts the swing assembly 23. Its function is to apply elastic force to the swing assembly 23 when the swing assembly 23 is not pressed by the switch button 24, so that the swing assembly 23 contacts the fence structure 2213 of the roller 221. The signal generating module 225 is disposed near the roller swing seat 222, and its function is to detect the rotation of the roller 221 and output a corresponding rotation signal. In this preferred embodiment, the elastic element 224 is a torsion spring, and the signal generating module 225 includes a light emitter 2251 and a light receiver 2252. Among them, the light emitter 2251 is located on the first side of the roller swing seat 222, and its function is to generate a light beam and make the light beam pass through the fence structure 2213. The light receiver 2252 is located at the second side of the roller swing base 222 , and its function is to receive the light beam passing through the fence structure 2213 and generate a corresponding rotation signal.

Next, the structure of the swing assembly 23 is described. Referring to FIG. 5 and FIG. 6 , the swing assembly 23 includes a body 231, a first contact portion 232, and a second contact portion 233. The body 231 has a fixing hole 2311, and 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 is close to the roller 221. When the swing assembly 23 is close to the roller 221, it can contact the fence structure 2213. The second contact portion 233 is disposed on the second end of the body 231, and it can be pushed against by the switch button 24 to make the swing assembly 23 swing relative to the roller swing seat 222. In this 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 and is not limited thereto. In another preferred embodiment, the first contact portion and the second contact portion can be fixed to the body in any manner.

Next, the operation of the wheel mouse 2 of the present invention will be described. Please refer to FIG. 6 and FIG. 7. FIG. 7 is another partial structural schematic diagram of the wheel mouse of the present invention in the second paragraph sense mode in the first preferred embodiment. When the user hopes that the wheel mouse 2 can provide a paragraph sense, 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 component 23. Therefore, the swing component 23 is subjected to the elastic force of the elastic element 224 so that the first contact portion 232 contacts the fence structure 2213. At this time, the wheel module 22 enters the first paragraph sense mode, as shown in FIG. 6. When the user toggles the wheel 221, since the swing component 23 contacts the fence structure 2213, the user can feel the paragraph sense generated by the collision between the swing component 23 and the fence structure 2213.

On the contrary, when the user does not want the wheel mouse 2 to provide a sense of movement, 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 in a direction away from the fence structure 2213. As a result, the first contact portion 232 of the swing component 23 is away from the roller 221 and does not contact the fence structure 2213. At this time, the roller module 22 enters the second sense of movement mode, that is, when the user rotates the roller 221, there will be no sense of movement, as shown in FIG. 7 .

In addition, the present invention also provides another preferred embodiment with different functions from the above. Please refer to Figures 8 and 9 at the same time. Figure 8 is a partial structural exploded schematic diagram of the roller mouse of the present invention in the second preferred embodiment, and Figure 9 is a partial structural schematic diagram of the roller mouse of the present invention in the second preferred embodiment. The roller mouse 3 of the present invention includes a housing 31, a roller module 32, a swing assembly 33 and a switching module 34. The roller module 32 includes a roller 321, a roller swing seat 322, a fixing column (not shown in the figure), 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 structures and operating conditions in this preferred embodiment are substantially the same as those in the first preferred embodiment, so they are not repeated here. As for the differences between the two, there are mainly two. First, this preferred embodiment uses a switching module 34 to swing the swing assembly 33. Second, the structure of the signal generating module 325 that generates a roller rotation signal.

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

In FIG8 , 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 its function is to be driven by electricity to provide a rotational force. The cam structure 342 is connected to the power element 341, and can rotate according to the rotational force. When the cam structure 342 rotates to a first angle, the cam structure is in a position where it does not abut against the swing assembly 33, so that the swing assembly 33 is in contact with the fence structure 3213 by the force of the elastic element 324, so that the roller module 32 is in a first paragraph sense mode. On the contrary, when the cam structure 342 rotates to a second angle, the cam structure 342 abuts against the swing assembly 33, so that the swing assembly 33 swings in a direction away from the fence structure 3213, so that the roller module 32 is in a second paragraph sense mode.

Next, the structure of the signal generating module 325 for generating the roller signal in this embodiment is described. Referring to FIG. 8 and FIG. 9 at the same time, 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, while the circuit board 3252 is disposed on the side surface of the roller swing seat 322. The Hall sensor 3253 is disposed on the circuit board 3252 and is close to the magnetic element 3251. Its function is to detect the change of the magnetic field of the rotating magnetic element 3251 and generate a corresponding rotation signal.

There are two points that need to be explained in particular. First, according to the configuration of the switching module 34 disposed in the housing 31, the housing 31 has only a single housing opening 311, which corresponds to the roller module 32, and is not provided with 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 has only a plurality of openings 3222 corresponding to the rotation axis 3212, and is not provided with the plurality of second openings 2223 of the aforementioned preferred embodiment.

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

The above description is only a preferred embodiment of the present invention and is not intended to limit the claims of the present invention. Therefore, any other equivalent changes or modifications that do not deviate from the spirit disclosed in the present invention should be included in the claims of the present invention.
