Description

Mouse (Saggar)

Technical Field

The present invention relates to an input device, and more particularly, to a mouse capable of controlling cursor movement.

Background

Common peripheral input devices of a computer include a mouse, a keyboard, a trackball, etc., wherein the mouse is held by a palm of a user to control the movement of a cursor, which is in accordance with the operation habits of most users, so that the mouse is the most common input device.

First, the structure and function of the conventional mouse will be described, please refer to fig. 1, which is a schematic structural diagram of the conventional mouse connected to a computer system. The computer system 2 includes a host computer 21 and a computer screen 22, the host computer 21 is connected to the mouse 1 and the computer screen 22 respectively, the host computer 21 has a port 211, and the computer screen 22 can display a window 221 and a cursor 222 therein. The mouse 1 is capable of controlling the cursor 222 in response to the operation of the user, so that the host computer 21 can execute the corresponding command, and the mouse 1 includes a main body 10, a left button 11, a right button 12, a wheel 13 and a connecting line 14. The left key 11 is disposed on the body 10 and located at the left side of the roller 13, and the left key 11 is exposed outside the body 10 and can be pressed by a user to generate a left key signal. The right button 12 is similar to the left button 11, the right button 12 is disposed on the body 10 and located at the right side of the roller 13, and the right button 12 is also exposed outside the body 10 and can be pressed by a user to generate a right button signal. The roller 13 is disposed in the body 10 and partially exposed outside the body 10, and can be rotated by a user to generate a scrolling signal. The connecting wire 14 is disposed on the main body 10 and extends out from the main body 10, and functions to connect to the port 211 to establish a connection between the mouse 1 and the computer system 2.

Next, the internal structure of the conventional mouse will be explained. Please refer to fig. 2, which is a cross-sectional view of a conventional mouse. In the mouse 1, the main body 10 is disposed on the working surface T, and the mouse 1 further includes a circuit board 15, a sensing module 16 and a control unit 17. The sensing module 16 is disposed on the circuit board 15 and partially exposed out of the bottom opening 101 of the body 10, and functions to detect the movement of the body 10 and output a displacement signal, and the sensing module 16 includes a light emitting element 161, an optical lens 162 and an optical sensing element 163. The light emitting element 161 is disposed on the circuit board 15 and functions to generate the light beam B. The optical lens 162 is disposed in the body 30 and functions to allow the light beam B to pass through and refract the light beam B so as to project the light beam B on the working surface T located below the body 10. The optical sensing element 163 receives the light beam B reflected by the working surface T and generates a displacement signal according to the light beam B. The control unit 17 is disposed on the circuit board 15 and electrically connected to the optical sensing element 163.

The operation of generating the displacement signal is briefly described. When the mouse 1 is not moved on the working surface T, the light emitting element 161 generates the light beam B, and the light beam B is refracted by the optical lens 162, so that the light beam B is projected onto the working surface T. Next, the light beam B is reflected by the working surface T and enters the optical lens 162 again, and the light beam B passing through the optical lens 162 is received by the optical sensing element 163, at this time, the optical sensing element 163 generates a first working surface image. Next, when the user moves the mouse 1 to a certain position on the working surface T, the light beam B generated by the light emitting device 161 is received by the optical sensing device 163 through the optical lens 162, the working surface T and the path of the optical lens 162, and the optical sensing device 163 generates a second working surface image.

Next, the control unit 17 receives the first working surface image and the second working surface image from the optical sensing element 163, compares the difference between the first working surface image and the second working surface image to obtain the displacement amount of the main body 10 on the working surface T, and generates a displacement signal corresponding to the displacement amount. That is, when the user moves the mouse 1 on the working surface T, the displacement sensing device 16 detects the displacement of the main body 10 on the working surface T and generates a displacement signal according to the displacement. After the host computer 21 receives the displacement signal, the host computer 21 can move the cursor 222 on the computer screen 22 according to the displacement signal.

In response to the development of the mouse, the function of the mouse is increasingly enhanced, for example, the moving resolution of the mouse is greatly improved. The moving resolution of the mouse represents the sensitivity of the cursor of the computer host to move every distance of the mouse, and the larger the moving resolution is, the larger the sensitivity of the cursor to move is. When a user plays a computer game, the mouse needs to be moved quickly, so that the mouse needs high moving resolution; when the user only needs to process words, the mouse only needs low moving resolution. In order to avoid that the user must continuously change the appropriate mouse, a mouse with changeable moving resolution is provided on the market, and the mouse is provided with a switch which is pressed by the user to change the moving resolution of the mouse. For example, when the user touches the switch once, the moving resolution of the mouse is changed from 800dpi (dots Per inc) to 1600 dpi. When the user touches the switch once more, the moving resolution of the mouse is changed from 1600dpi to 800 dpi. Therefore, the mouse can change the moving resolution according to different use conditions.

However, although the moving resolution of the mouse can be changed, the mouse cannot be applied to various working surfaces, such as: the working surface made of transparent material (such as acrylic) will cause the light beam to penetrate, and reduce the reflection of the light beam, so the displacement signal will be affected.

Therefore, there is a need for a mouse that can change the resolution of movement and is adaptable to a variety of work surfaces.

The switch plate 351 is received in the receiving cavity 303 and can rotate in the receiving cavity 303 relative to the base 301 in response to the user's toggling. The switch board 351 includes a board 3511 and an extending column 3512, the board 3511 is received in the receiving cavity 303 and can rotate relative to the base 31, the board 3511 has a first opening 3513, a second opening 3514 and a third opening 3515, the first opening 3513 corresponds to the first sensing module 32, the second opening 3514 corresponds to the second sensing module 33, and the third opening 3515 corresponds to the third sensing module 34. The extending column 3512 is disposed on the plate 3511 and sequentially passes through the first housing opening 304, the first circuit board opening 311 of the circuit board 31, and the connecting frame 353. When the plate 351 rotates in the receiving cavity 303 relative to the base 301 and the first opening 3513 overlaps the second housing opening 305, the first sensing module 32 can be exposed outside the second housing opening 305. Similarly, when the plate 351 rotates in the receiving groove 303 relative to the base 301 and the second opening 3514 overlaps the second housing opening 305, the second sensing module 33 is exposed outside the second housing opening 305. In the preferred embodiment, the board 3511 and the circuit board 31 are circular, and the receiving groove 303 is a corresponding circular groove.

Fig. 4 shows the external state of the base 301 of the mouse 3, and the switch board 351 further includes a toggle portion 3516 disposed on the board 3511 and exposed outside the first housing opening 304 of the base 301, which can be toggled by a user with a nail, a screwdriver, or any other tool, so that the board 3511 can be rotated, and the switch module 35 can be driven. In the preferred embodiment, the extension column 3512 and the toggle portion 3516 are integrally formed with the switch board 351.

The fixing frame 352 may be fixed on the upper cover 302 or the base 301 corresponding to the inner space configuration of the housing 30 and located between the upper cover 302 and the base 301. The connection frame 353 is located between the upper cover 302 and the base 301, and can establish a connection between the switch board 351 and the circuit board 31, so that the circuit board 31 can rotate synchronously with the switch board 351. The connecting frame 353 includes a body 3531 and a plurality of connecting posts 3532, the body 3531 has a central hole 3533, and the extending post 3512 of the switch board 351 can extend into the central hole 3533 through the first circuit board opening 311 to connect the switch board 351 and the connecting frame 353. The connecting posts 3532 are connected to the body 3531 and respectively penetrate through the second circuit board openings 312 of the circuit board 31 to contact the board 351, wherein the board 351 and the connecting posts 3532 can further establish the connection between the switch board 351 and the connecting frame 353 by a connecting means, and simultaneously establish the connection between the switch board 351 and the circuit board 31. In the preferred embodiment, the connection means is a screw-locking manner for combining the switch board 351 and the connection frame 353, which is only used for illustration and not limited thereto, and other connection means are, for example: the switching board and the connecting frame are provided with holes and corresponding convex columns which are combined in a clamping way.

It should be noted that, since the connection relationship between the switch board 351 and the connection frame 353 is established, the connection frame 353 can rotate synchronously with the switch board 351. And since the plurality of connecting posts 3532 respectively penetrate through the corresponding second circuit board openings 312, when the connecting frame 353 is driven by the switching board 351 to rotate, the connecting frame 353 can drive the circuit board 31 to rotate. In other words, the switch board 351, the connecting frame 353 and the circuit board 31 can rotate synchronously.

Referring to fig. 3, fig. 4 and fig. 5, the rotating element 354 is respectively connected to the fixed frame 352 and the connecting frame 353, and can be driven by the switching plate 351 to rotate, and the rotating element 354 includes a first sheet-shaped body 3541 and a second sheet-shaped body 3542. The first sheet-like member 3541 is fixed to the fixing frame 352, and the second sheet-like member 3542 is fixed to the main body 3531 of the connecting frame 353 and is rotatable with respect to the first sheet-like member 3541. When the plate 3511 rotates, the connecting posts 3532 rotate synchronously with the plate 3511, and the body 3531 drives the second sheet 3542 to rotate relative to the first sheet 3541. In the preferred embodiment, the rotating element 354 is a Hinge (Hinge) structure, and the second blade 3542 is limited to rotate only about 180 degrees relative to the first blade 3541.

The detecting element 355 is disposed on the circuit board 31 and located at the periphery of the circuit board 31, and a portion thereof protrudes from the periphery of the circuit board 31, and functions to detect the rotation state of the switch board 351 and output a corresponding detecting signal. On the other hand, the housing 30 further includes a plurality of bumps 306 disposed at the periphery of the receiving groove 303, and each bump 306 corresponds to one

sensing module

32, 33 or 34. When the circuit board 31 is driven to rotate relative to the base 301, the detecting element 355 is triggered by the bump 306 in response to the rotation of the circuit board 31 to output a corresponding detecting signal. The control unit 356 is disposed on the circuit board 31 and electrically connected to the detecting element 355, the first sensing module 32, the second sensing module 33, and the third sensing module 34, and can control the operation states of the first sensing module 32, the second sensing module 33, and the third sensing module 34 in response to the received detection signal. The control unit 356 has a first state value, a second state value and a third state value by default, and when the control unit 356 receives a detection signal corresponding to the first state value, the control unit 356 can control the operation states of the first sensing module 32, the second sensing module 33 and the third sensing module 34 according to the first state value.

The structures of the first sensing module 32, the second sensing module 33, and the third sensing module 34 are explained next. Referring to fig. 3, fig. 4 and fig. 6, fig. 6 is a schematic cross-sectional view of a mouse according to a first preferred embodiment of the present invention. The first sensing module 32 includes a first light emitting element 321, a first optical lens 322 and a first optical sensing element 323, the second sensing module 33 includes a second light emitting element (not shown), a second optical lens 332 and a second optical sensing element 333, and the third sensing module 34 includes a third light emitting element (not shown), a third optical lens 342 and a third optical sensing element 343. Fig. 6 shows a detailed structure of the first sensing module 32, in which the first light emitting element 321 is disposed on the circuit board 31 and electrically connected to the control unit 356, and functions to generate the light beam B. The first optical lens 322 is disposed on the bottom 300 of the housing 30 for the light beam B to pass through. The first optical sensing element 323 is disposed on the circuit board 31 and electrically connected to the control unit 356, and is capable of receiving the light beam B passing through the first optical lens 322 to generate a working surface image. The second sensing module 33 and the third sensing module 34 are identical in structure to the first sensing module 32, but differ only in that the first light emitting element 321 of the first sensing module 32 is a visible light emitting element, the second light emitting element of the second sensing module 33 is a invisible light emitting element, and the third light emitting element of the third sensing module 34 is a Laser (Laser) light emitting element, and other structures are identical, so that descriptions thereof are omitted. In other words, the first sensing module 32 is a visible light sensing module, the second sensing module 33 is a invisible light sensing module, and the third sensing module 34 is a laser sensing module. In addition, the operation of the first sensing module 32, the second sensing module 33 and the third sensing module 34 for generating the displacement signal is similar to the prior art and is not repeated.

Next, a case where the operating state of the mouse 3 is changed by the switching module 35 will be described. Referring to fig. 3, fig. 4 and fig. 7, fig. 7 is a partial structural schematic diagram of the operation of the switching module of the mouse in the first preferred embodiment of the present invention. When the user does not need to have a high moving resolution, the user can toggle the switch board 351 by the toggle portion 3516, so that the board 3511 rotates in the accommodating groove 303 in the first rotating direction C1 relative to the base 301, at this time, the connecting frame 353 is driven to rotate synchronously with the board 3511 in response to the rotation of the board 3511, and the connecting frame 353 also drives the circuit board 31 to rotate. On the other hand, the rotating element 35 is driven by the rotating switching plate 351 to rotate the second sheet-like body 3542 relative to the first sheet-like body 3541. During the rotation of the circuit board 31, the detecting element 355 is triggered by the bump 306 corresponding to the first sensing module 32 in response to the rotation of the circuit board 31 to output a detecting signal corresponding to the first state value (e.g., 1) to the control unit 356. The control unit 356 can drive the first sensing module 32 according to the first state value, and control the second sensing module 33 and the third sensing module 34 to enter a sleep mode, i.e. the mouse 3 is in the low-motion-resolution operation mode. By the above operation of the switching module 35, the first opening 3513 overlaps the second housing opening 305, so that the first sensing module 32 can be exposed outside the second housing opening 305.

Similarly, the user can utilize the switching module 35 to perform the above operation to change the mouse 3 to the state where the second sensing module 33 is exposed outside the second housing opening 305, and the circuit board 31 continues to rotate in the first rotation direction C1, so that the detecting element 355 is sequentially triggered by the two bumps 306 corresponding to the second sensing module 33 and the third sensing module 34 to output the detecting signal corresponding to the third state value (e.g. 3) to the control unit 356. The control unit 356 can drive the third sensing module 34 according to the second state value, and control the first sensing module 32 and the second sensing module 33 to enter a sleep mode, i.e. the mouse 3 is in an operation mode with high moving resolution. When the circuit board 31 rotates in the second rotation direction C2, and the detecting element 355 is triggered by the bump 306 corresponding to the second sensing module 33 to output a detection signal corresponding to the second state value (e.g. 2) to the control unit 356, the following operation of the first sensing module 34 is similar to the above operation, and will not be described again.

In the preferred embodiment, the detecting element 3552 is a counter, and when the plate 3511 rotates relative to the base 301 in the first rotating direction C1 and the detecting element 355 is triggered once, the count value of the detecting element 355 is increased by 1. On the contrary, when the plate 3511 rotates relative to the base 301 in the second rotation direction C2 and the detecting element 355 is triggered once, the count value of the detecting element 355 decreases by 1.

It should be noted that the extending column 3512 of the switch board 351 is a hollow structure, and the hollow structure inside the switch board can accommodate wires (not shown) connected to the circuit board 31 to complete the circuit configuration of the circuit board 31. Since the wires can be accommodated in the extension column 3512, when the switching plate 351 rotates, the wires will not rotate along with the extension column 3512, and the wires will not be twisted and damaged due to over-rotation.

According to the above operation, the user can control different sensing modules to be exposed outside the second housing opening 305 according to the requirement, so as to select the appropriate moving resolution. In addition, since the first sensing module 32, the second sensing module 33 and the third sensing module 34 are different types of sensing modules, they are suitable for different types of working surfaces, and thus, in addition to the moving resolution, the user can select a suitable sensing module according to the requirement, so that the mouse of the present invention can operate on a suitable working surface. In other words, the mouse of the invention not only can change the moving resolution, but also can run on various working surfaces.

In addition, the present invention further provides a second preferred embodiment different from the above. Referring to fig. 8 and 9, fig. 8 is an exploded view of a mouse according to a second preferred embodiment of the present invention, and fig. 9 is a partially exploded view of another perspective of the mouse according to the second preferred embodiment of the present invention. The mouse 4 includes a housing 40, a circuit board 41, a first sensing module 42, a second sensing module 43, a third sensing module 44, a switching module 45, and an operation module 46. The housing 40 includes a base 401, an upper cover 402, a receiving groove 403, a first housing opening 404 and a second housing opening 405, and the switching module 45 includes a switching board 451, a fixing bracket 452, a connecting bracket 453, a rotating element 454, a plurality of detecting elements 455 and a control unit 456. The structure and function of each component of the mouse 4 are substantially the same as those of the mouse 3 of the above preferred embodiment, and the description thereof is omitted. The mouse 4 of the preferred embodiment is different from the aforementioned preferred embodiment in the structure and operation of the switching module 45.

Fig. 8 shows that a plurality of detecting elements 455 are disposed in the switching module 45, and the detecting elements 455 are disposed on the circuit board 41 and between the two sensing modules, which do not partially extend out of the circuit board as in the previous preferred embodiment. On the other hand, the rotating element 454 comprises a first sheet 4541 and a second sheet 4542, and the second sheet 4542 is rotatable relative to the first sheet 4541. In the preferred embodiment, the second sheet 4542 is made of a magnetic material, so that the second sheet 4542 can induce a magnetic field change when rotating, and the detecting element 455 is a hall sensor.

When the switching module 45 operates, the second sheet 4542 rotates relative to the first sheet 4541 and passes over the detection element 455, and the detection element 455 can output a corresponding detection signal because the magnetic field changes in the vicinity of the detection element 455 and can be triggered by the second sheet 455. Therefore, the control unit 456 can perform subsequent related operations according to the detection signal, and the operations are the same as those of the foregoing preferred embodiment, and thus are not described again. In addition, since the operation of the switching module 45 is different from that of the foregoing preferred embodiment, the housing 40 of the present preferred embodiment does not need to have a plurality of bumps therein.

It should be noted that the mouse of the present invention is provided with a detecting element 355 of a mechanical triggering type and a detecting element 455 of a magnetic induction triggering type, which are only used for illustration and not limited thereto. In addition to the above detection methods, the mouse of the present invention can also be performed by using detection methods known to those skilled in the art, such as: optical sensing may be used. An optical sensor is arranged on the circuit board as a detection element, and a light source capable of generating light beams is arranged on the first sheet-shaped body, so that the optical detection can be carried out when the first sheet-shaped body rotates. Other known detection methods can also be applied to the mouse of the present invention, and are not described in detail.

According to the above, the mouse of the present invention provides a plurality of sensing modules, and the required moving resolution can be selected and used according to different situations. The switching module in the mouse acts by matching a mechanical structure with a simple detection element and a control unit, so the mouse has the advantages of simple structure and low cost. In addition, because different types of sensing modules are arranged in the mouse, a user can select and use a proper sensing module according to the type of the working surface, and therefore, the mouse can operate on different types of working surfaces.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, so that other equivalent changes and modifications without departing from the spirit of the present invention are intended to be included within the scope of the appended claims.
