In particular, the proportional relationships and relative positions of the various elements in the drawings are for exemplary purposes only, and do not represent the actual status of the implementation of this application.

FIG. 1 to FIG. 4 are schematic diagrams of the first embodiment of the computer mouse of the present application, wherein the schematic diagrams of the scroll wheel of the computer mouse 1 of the present application are shown (in addition, it should be noted that the computer mouse in FIGS. 1 to 4 (The left button, right button, bottom optical sensor, rear palm rest and other structures are not shown). In this embodiment, the computer mouse 1 can scroll a computer screen through the application of a wheel force. As shown in the figure, the roller portion of the computer mouse 1 mainly includes a driven body 11, a roller 12, and a rotation. The sensor 13, a pressure sensor 14, a control module 15 and a pressing switch 17.

Please refer to FIGS. 1 and 2 in combination. In this embodiment, the driven body 11 is, for example, a roller shaft. In this embodiment, both ends of the driven body 11 are respectively mounted on the rotation sensor 13 and the push switch. 17 on.

The roller 12 is arranged on the driven body 11. When the roller 12 rotates, the driven body 11 will be driven, and the output screen of the computer connected to the computer mouse 1 can perform the scrolling operation. Among them, the driven body 11 also has a The driven body middle shaft 110 and an embedding part 113 extend from the driven body middle shaft 110 to the roller 12. The embedding part 113 can be embedded in the roller 12 to complete the setting of the roller 12.

In a specific embodiment, the roller 12 can receive a rotating force applied by the user to the roller 12, and the rotating force can be divided into (1) a rotating force, which is aligned with the arc surface of the roller 12 (as shown in FIG. 3 or In Figure 4, they are indicated by the marked lines of symbols D1 and D2 respectively.) The roller 12 can be driven to rotate, and (2) the pressing force passes through the center of the roller 12, which is perpendicular to the arc surface of the roller 12 (as shown in FIG. In FIG. 4, each is indicated by a marked line with a symbol F), so that the roller 12 is deformed inwardly toward the hollow cavity.

The pressure sensor 14 is used to sense the force of the pressing force F applied by the user on the roller 12 and output a pressure sensing signal according to the sensed result. The pressure sensor 14 may be disposed in a roller hollow cavity of the roller 12. When the roller 12 is contracted and deformed due to receiving a pressing force, the roller 12 abuts against the pressure sensor 14, so that the pressure sensor 14 may The magnitude of the pressing force applied to the roller 12 is sensed.

Please refer to FIGS. 1 to 4. The part of the roller 12 exposed outside the casing 18 of the computer mouse 1 is defined as the roller pressing part 121. Under normal use, only the roller pressing part 121 on the roller 12 can be used. The user applies force; because other parts of the roller 12 (the part not belonging to the wheel pressing part 121) are housed in the main casing 18 of the computer mouse 1, the user cannot access the force for operation.

It should be noted that since the user operates the computer mouse 1 to apply force to the roller 12, the actual contact area between his finger and the roller 12 will not continuously stay directly above the roller 12. For example, as shown in FIG. 4, when the user wants to scroll the computer screen upward, his finger is tied to the area between the twelve and three o'clock directions in the circular contour of the roller 12 to push the roller 12 forward. As shown in FIG. 3, when the user wants to scroll the computer screen downwards, his user pushes the roller 12 to rotate backwards within the range of the direction between nine and twelve o'clock in the circular outline of the roller 12. In view of this, in order to more accurately sense the pressing force exerted by the user on the wheel 12, the area between the clock positions of nine to three o'clock in the circular contour of the wheel 12 (that is, an angle range of 180 degrees) can be defined as The roller pressing portion 121, and the pressure sensor 14 is disposed below the roller pressing portion 121. In this way, no matter the user rotates the roller 12 forward or backward, the pressure sensor 14 can accurately sense that the user operates the roller 12 The magnitude of the applied pressing force F (as shown in Figs. 3 to 4 and 7 to 8).

The rotation sensor 13 detects the rotation direction and degree of the driven body 11 to indirectly sense the rotation direction and degree of the roller 12, and outputs a rotation sensing signal according to the sensed result. In a specific embodiment, the rotation sensing signal output by the rotation sensor 13 represents the number of rotations and the rotation direction of the roller 12.

As shown in FIG. 2 or FIG. 6, the computer mouse 1 further includes a supporting member 16, which mainly includes an arc-shaped supporting portion 161 and an elastic arm 162. The elastic arm 162 is used to provide elastic support for the arc-shaped supporting portion 161. There is an arc-shaped storage space formed between the arc-shaped support portion 161 and the wheel pressing portion 121. The pressure sensor 14 is stored in the arc-shaped storage space, and the arc-shaped support portion 161 is disposed below the pressure sensor 14. ． In this way, when the roller 12 is deformed inwardly after receiving the pressing force F, the roller pressing portion 121 applies pressure to the pressure sensor 14 from top to bottom, and the arc-shaped supporting portion 161 supports the pressure sensor 14 upward to make the pressure sense. The detector 14 can accurately measure the pressing force transmitted by the roller pressing portion 121.

Specifically, please continue with FIG. 2 or FIG. 6. A roller hollow cavity is provided in the roller 12, which has an arc-shaped inner surface. The arc-shaped supporting portion 161 of the support 16 is disposed on the roller of the roller 12. Inside the hollow cavity, and the arc-shaped supporting portion 161 and the arc-shaped inner surface are kept separated to form an arc-shaped storage space, and the pressure sensor 14 is disposed at the top of the arc-shaped storage space to sense the application to the roller 12 On the press. In one embodiment, the arc-shaped inner surface, the arc-shaped supporting portion 161 and the arc-shaped receiving space are extended to form a complete annular profile, as shown in FIGS. 1 and 2.

In addition, the pressure sensor 14 of the present application may be, for example, designed as an annular body to completely surround the periphery of the arc-shaped support portion 161, so as to provide the pressure sensor 14 to sense the pressing force F applied to any position on the roller 12. . However, it is not limited to this. In the embodiments shown in FIG. 5 to FIG. 8, the range of the area between nine and three o'clock in the circular contour of the roller 12 can also be set according to the aforementioned roller pressing portion 121. The pressure sensor 14 is designed as a "hook", so that it is located only in the area between nine and three o'clock in the circular outline of the roller 12, without having to completely surround the entire arc-shaped support portion. 161 saves material cost of the pressure sensor 14.

In addition, please refer to FIG. 2 and FIG. 6. The driven body 11 of the present application also has a force transmission portion 114. The arc-shaped support portion 161 can also force the driven body 11 to bend by transmitting the force through the force transmission portion 114, thereby The driven body 11 is driven to move vertically downward. In this embodiment, the force transmitting portion 114 and the embedding portion 113 of the driven body 11 may be formed of plate-shaped bodies that intersect perpendicularly.

The control module 15 is used for receiving the rotation sensing signal output from the rotation sensor 13 and the pressure sensing signal output from the pressure sensor 14. In this embodiment, the control module 15 and the rotation sensing The sensor 13 and the pressure sensor 14 are disposed on the printed circuit board 10 at the bottom of the mouse, so that the control module 15 is electrically coupled to the rotation sensor 13 and the pressure sensor 14, respectively, so as to receive the rotation sensor 13 The output rotation sensing signal and the pressure sensing signal output from the pressure sensor 14.

Furthermore, after the control module 15 receives the rotation sensing signal output from the rotation sensor 13 and the pressure sensing signal output from the pressure sensor 14, it can control the computer screen scrolling speed according to the rotation sensing signal. In the present invention, the scroll speed of the computer screen is positively related to the following two parameters: (1) the number of rotations of the roller 12, and (2) the force of the pressing force F measured by the pressure sensing signal; that is, (a) the On the premise that the number of rotations of the roller is the same, if the pressing force F applied to the roller 12 during the rotation is large, the computer screen scrolling distance is longer; if the pressing force F applied to the roller 12 is small during the rotation, the computer screen The shorter the scrolling distance; (b) On the premise of the same pressing force F, if the number of rotations of the wheel is more, the computer screen scrolling distance is longer; if the number of rotations of the wheel is less, the computer screen scrolling distance is shorter ． Therefore, the technical effect of simultaneously determining the scrolling speed and the vertical scrolling distance of the computer screen according to the degree of rotation of the roller 12 and the force of the pressing force F applied to the roller 12 is achieved, so as to meet the different reading needs of users, and improve User experience.

In a specific embodiment, the control module 15 receives the number of rotations and the rotation direction of the roller 12 sensed by the rotation sensor 13 and the force of the pressing force F sensed by the pressure sensor 14 respectively, and according to the roller The rotation direction of 2 determines the scrolling direction of the computer screen, and the vertical scrolling distance of the computer screen is determined according to the number of rotations of the scroll wheel 12 and the pressing force F, and the computer mouse 1 can rotate on the scroll wheel 12 Under the condition that the number of turns is constant, the vertical scrolling distance of the computer screen is determined according to the pressing force F applied by the user to the roller 12, that is, when the pressing force F becomes larger, the vertical scrolling of the computer screen The moving distance becomes longer, and when the pressing force F becomes smaller, the vertical scrolling distance of the computer screen becomes shorter.

As shown in Table 1, it is an embodiment table in which the pressing force F applied to the computer mouse 1 and the vertical scrolling distance of the computer screen change in a non-linear manner, in which the number of rotations of the roller 12 is constant. Under the conditions, when the pressing force F applied to the roller 12 is 1 unit of pressure, the vertical scrolling distance of the computer screen is 1 distance unit (for example, the computer scrolls a page); when the pressing force applied to the roller 12 is 1 When F is increased to 2 pressure units, the vertical scrolling distance of the computer screen can be increased to 4 distance units (for example, the computer scrolls four pages); when the pressing force F applied to the roller 12 is 3 pressure units, The vertical scrolling distance of the computer screen is increased to 9 distance units (for example, computer scrolling 9 pages); when the pressing force F applied to the roller 12 is 4 pressure units, the vertical scrolling distance of the computer screen is increased to 16 Distance units (such as a computer scrolling through 16 pages), and so on.

However, it is not limited to this, and the present application may also set the pressing force F applied to the computer mouse 1 and the vertical scrolling distance of the computer screen in a linear manner according to actual operation requirements, as follows: (Table 2)

As shown in Table 2, under the condition that the number of rotations of the roller 12 is constant, when the pressing force F applied to the roller 12 is one pressure unit, the vertical scrolling distance of the computer screen is one distance unit. ; When the pressing force F applied to the roller 12 is increased to 2 pressure units, the vertical scrolling distance of the computer screen is correspondingly increased to 2 distance units; When the pressing force F applied to the roller 12 is 3 pressure units , The vertical scrolling distance of the computer screen is increased to 3 distance units accordingly; when the pressing force F applied to the roller 12 is 4 pressure units, the vertical scrolling distance of the computer screen is increased to 4 distance units, And so on.

It should be noted that the change relationship between the pressing force F and the vertical scrolling distance of the computer screen is not limited to the data settings shown in Table 1 or Table 2. The user can also define it by using relevant editing software The relationship between the pressing pressure F and the vertical scrolling distance of the computer screen to meet the different needs of users.

F can be transmitted to the driven body 11 through the pressure sensor 14 and the arc-shaped supporting portion 161 to drive the driven body 11 to move vertically downward, thereby pressing the trigger switch 17 provided below the driven body 11. In this embodiment, when the pressing switch 17 is triggered by the pressing of the driven body 11, a pressing instruction can be output to the control module 15, and if the current computer screen is in a state to be scrolled, the control mode is controlled. The group 15 can execute the pressing instruction for browsing the information currently displayed on the computer screen.
