The present invention relates to a mouse device, in particular to a mouse device that uses magnetic attraction to drive the scroll wheel to return.

In the current mouse design, in order to improve the operational functionality of the mouse, in addition to using the mouse wheel to perform forward and backward rotation operations (such as controlling the vertical scroll bar of the window operation interface to move up and down), it can be further configured There is a roller bias function to allow users to perform operations in the corresponding axis by biasing the roller laterally with their fingers (such as controlling the horizontal scroll bar of the window operation interface to move left and right). The common structural design is a slender elastic The arm is connected to the mouse base and the bearing seat for accommodating the roller, whereby the bearing seat can be arranged on the mouse base so as to be able to deflect left and right by utilizing the flexibility of the elastic arm structure. In this way, through the above design, when the roller accommodated in the bearing seat is subjected to lateral force, the bearing seat can be deflected correspondingly to trigger the micro-motion on the mouse circuit board as the elastic arm is compressed and deformed. switch to complete the corresponding input operation.

However, since the above-mentioned bearing seat and the mouse base are only connected by an integrally formed slender elastic arm, the above-mentioned design usually has the problem that the elastic arm structure is not easily formed and the elastic arm is prone to breakage after repeated deflection and deformation for a period of time. The problem.

Therefore, one of the objectives of the present invention is to provide a mouse device that uses magnetic attraction to drive the scroll wheel to return to solve the above problems.

According to an embodiment, the mouse device of the present invention includes a base, an upper cover, a bearing base, a circuit board, and a scroll wheel. The upper cover is closed on the base and forms a slot, and the front end of the upper cover has a first magnetic element. The carrier is movably suspended between the upper cover and the base and has a second magnetic element, a first magnetic surface of the first magnetic element and a second magnetic surface of the second magnetic element are parallel to each other relatively. The circuit board is arranged on the base and has a switch device at a position corresponding to the bearing base. The roller is rotatably disposed in the bearing seat and protrudes from the slot. When the roller is forced to drive the bearing seat to move relative to the base, the bearing seat triggers the switch device, and the second magnetic member deflects relative to the first magnetic member with the movement of the bearing seat, so that the The second magnetic surface is deflected away from the first magnetic surface. When the roller is released, the magnetic attraction between the first magnetic member and the second magnetic member drives the second magnetic surface to deflect parallel to the first magnetic surface, so that the bearing seat returns to its original position.

To sum up, the magnetic return design of the scroll wheel adopted in the present invention not only allows the user to complete the corresponding input operation (for example, control the horizontal scroll bar of the window operation interface left and right) by biasing the side of the finger or pressing down the scroll wheel traverse or close browser paging, etc.) to improve the operating functionality of the mouse, and at the same time, it can also effectively solve the problem that the bearing seat and the mouse base mentioned in the prior art are only connected by an integrally formed slender elastic arm. The elastic arm structure is not easy to form and the elastic arm is easy to break, thereby prolonging the service life of the mouse device.

The advantages and spirit of the present invention can be further understood from the following detailed description of the invention and the accompanying drawings.

Please refer to FIG. 1, FIG. 2, FIG. 3, and FIG. 4. FIG. 1 is a partial exploded schematic diagram of a mouse device 10 according to an embodiment of the present invention, and FIG. 2 is FIG. 1 Figure 3 is a schematic top view of the mouse device 10 in Figure 2 when a scroll wheel 20 is deflected to the left, Figure 4 is a schematic diagram of the mouse device 10 in Figure 2 on the scroll wheel 20 is a schematic top view when it is deflected to the right. As shown in Figure 1, Figure 2, Figure 3 and Figure 4, the mouse device 10 includes a base 12, an upper cover 14, a bearing seat 16, a For the circuit board 18 and the scroll wheel 20 , the base 12 and the upper cover 14 are omitted in FIGS. 3 and 4 in order to clearly show the operating relationship of the internal components of the mouse device 10 . The upper cover 14 is closed on the base 12 and has a slot 22 formed thereon. The front end of the upper cover 14 has a first magnetic element 24 , and the bearing base 16 is movably suspended between the upper cover 14 and the base 12 and has a second magnetic element 26, wherein as can be seen from FIG. 2, a first magnetic surface 25 of the first magnetic member 24 and a second magnetic surface 27 of the second magnetic member 26 are parallel and opposite to each other (preferably separated by a distance, but not Limited by this, it can also be designed with surfaces attached to each other) to generate magnetic attraction, one of the first magnetic member 24 and the second magnetic member 26 can be a magnet, and the first magnetic member 24 and the second magnetic member 26 The other one can be a magnet or a magnetically permeable material (eg, iron or other metal). The scroll wheel 20 is rotatably disposed in the bearing base 16 and protrudes from the slot 22 to allow the user to perform forward and backward rotation operations by pushing the scroll wheel 20 with fingers (for example, to control the vertical scroll bar of the window operation interface to move up and down).

In this embodiment, a pair of cantilever arms 28 may preferably extend downward at the position of the upper cover 14 corresponding to the support base 16 , and the support base 16 is movably engaged between the cantilever arms 28 so as to be movably suspended from the base. 12 (but not limited thereto, in another embodiment, it can also adopt a design in which the base 12 extends upward to form a support for the bearing base 16 to be suspended on the base 12 ), more specifically, as As shown in FIG. 1 , each cantilever 28 can be formed with a guide groove 30 and an engaging hole 32 , and a positioning post 34 protrudes outward from the position of the bearing base 16 corresponding to the guide groove 30 . Through the above-mentioned guide groove positioning design , in the process of assembling the mouse device 10, the positioning post 34 can be accurately moved along the guide groove 30 to the position of engaging with the engaging hole 32, so that the bearing seat 16 carrying the roller 20 can be movably engaged with the engaging hole 32. Between the cantilevers 28 of the upper cover 14 , the assembly between the bearing base 16 and the upper cover 14 can be quickly completed, thereby reducing assembly tolerances and effectively eliminating the assembly gap between the upper cover 14 , the bearing base 16 and the rollers 20 .

In addition, the circuit board 18 is disposed on the base 12 and has a switch device 36 at a position corresponding to the bearing base 16 . More specifically, in this embodiment, the switch device 36 may include at least one first switch 38 (in the first Figures 3-4 show two, but not limited thereto) and a second switch 40 , and the bearing base 16 may additionally have a trigger post 42 . The first switch 38 is preferably a micro switch and is located on both sides of the carrier 16, and the second switch 40 is preferably a micro switch and is located below the trigger post 42, so as to allow the user to pass the bias or The effect of triggering the switch device 36 is achieved by pressing the roller 20 down. It should be noted that the switch configuration of the switch device 36 is not limited to the above-mentioned embodiment, and a one-way triggering design can also be adopted to simplify the scroll wheel triggering design of the mouse device 10. For example, in another embodiment, the switch The device 36 can be a single micro switch and is located below the trigger post 42 so as to provide a one-way trigger function in which the user can press the roller 20 to depress the trigger switch device 36 .

Through the above design, as shown in FIGS. 2 and 3, when the roller 20 is biased to the left by the lateral force f1, the bearing seat 16 will be magnetically attracted to each other by the first magnetic member 24 and the second magnetic member 26. Under the influence, the first switch 38 on the left side is deflected relative to the first magnetic member 24 (it can be seen as being deflected clockwise in FIG. 3 ) until the bearing seat 16 laterally abuts against the first switch 38 on the left side. In this way, the carrier 16 can deflect to trigger the first switch 38 to complete the corresponding input operation (eg, control the horizontal scroll bar of the window operation interface to move horizontally to the left). When the above-mentioned triggering operation of the biasing roller 20 is completed and the roller 20 is released and no longer subjected to force, the magnetic attraction between the first magnetic member 24 and the second magnetic member 26 can drive the second magnetic surface 27 from the third magnetic surface 27 The position shown in the figure is deflected back to the position parallel to the first magnetic surface 25 as shown in FIG. The initial non-deflected position is shown, so that the roller 20 can automatically return to its original position.

On the other hand, as shown in FIGS. 2 and 4, when the roller 20 is biased to the right by the lateral force f2, the bearing seat 16 will be magnetically attracted to each other by the first magnetic member 24 and the second magnetic member 26. Under the influence, the first switch 38 on the right side is deflected relative to the first magnetic member 24 (it can be seen as being deflected in the counterclockwise direction in FIG. 4 ) until the bearing seat 16 laterally abuts against the first switch 38 on the right side. In this way, the carrier 16 can deflect to trigger the first switch 38 to complete the corresponding input operation (eg, control the horizontal scroll bar of the window operation interface to move horizontally to the right). When the above-mentioned triggering operation of the biasing roller 20 is completed and the roller 20 is released and no longer subjected to force, the magnetic attraction between the first magnetic member 24 and the second magnetic member 26 can drive the second magnetic surface 27 from the fourth magnetic surface 27 The position shown in the figure is deflected back to the position parallel to the first magnetic surface 25 as shown in FIG. The initial non-deflected position is shown, so that the roller 20 can automatically return to its original position.

The first magnetic member 24 is deflected downward (it can be seen as being deflected clockwise in FIG. 6 ) until the trigger column 42 triggers the second switch 40 . In this way, the bearing seat 16 can be pressed down to trigger the second switch 40 to complete the corresponding input operation (such as closing browser paging, etc.). At the same time as the above-mentioned triggering operation of pressing the roller 20 is completed and the roller 20 is released and no longer subjected to force, the magnetic attraction between the first magnetic member 24 and the second magnetic member 26 can drive the second magnetic surface 27 from the sixth The position shown in the figure is deflected upwardly back to the position parallel to the first magnetic surface 25 as shown in FIG. The initial undeflected position is shown, so that the roller 20 can automatically return to its original position.

To sum up, the magnetic return design of the scroll wheel adopted in the present invention not only allows the user to complete the corresponding input operation (for example, control the horizontal scroll bar of the window operation interface left and right) by biasing the side of the finger or pressing down the scroll wheel traverse or close browser paging, etc.) to improve the operating functionality of the mouse, and at the same time, it can also effectively solve the problem that the bearing seat and the mouse base mentioned in the prior art are only connected by an integrally formed slender elastic arm. The elastic arm structure is not easy to form and the elastic arm is easy to break, thereby prolonging the service life of the mouse device.

It is worth mentioning that the triggering design of the switch device of the present invention is not limited to the triggering design of the micro switch mentioned in the above-mentioned embodiment, and it can also adopt the optical triggering design. For example, please refer to FIG. A partial three-dimensional schematic diagram of a mouse device 10 ′ proposed by another embodiment of the invention, wherein in order to clearly show the internal components of the mouse device 10 ′, the base 12 and the upper cover 14 are omitted in FIG. 7 and A circuit board 18 ′ is partially illustrated, and the elements mentioned in this embodiment and the above-mentioned embodiments have the same numbers, which means they have the same structure or function, and the related descriptions are not repeated here. In this embodiment, the mouse device 10' includes a base 12, an upper cover 14, a bearing base 16', a circuit board 18' and a scroll wheel 20. The circuit board 18' has a switch device 36' at a position corresponding to the bearing base 16', The switch device 36' may include at least one first switch 38' (only one is shown in FIG. 7, but not limited thereto) and a second switch 40', and the bearing base 16' corresponds to the first switch 38' and The position of the second switch 40' can be extended downward to form a trigger column 17, the first switch 38' can be an infrared transceiver switch and is located on one side of the carrier 16', and the second switch 40' can be an infrared transceiver The switch is located under the trigger post 17, whereby the user can generate the effect of triggering the first switch 38' by blocking the optical sensing of the first switch 38' by the trigger post 17 by means of the biasing roller 20, or The effect of triggering the second switch 40 ′ by blocking the optical sensing of the second switch 40 ′ by the trigger column 17 can be generated by pressing the roller 20 down. As for the description of the above-mentioned optical blocking and triggering design, it is common In the prior art, detailed descriptions are omitted here. It should be noted that the switch configuration of the switch device 36 ′ is not limited to the above-mentioned embodiment, and a one-way trigger design can be adopted instead to simplify the scroll wheel trigger design of the mouse device 10 ′. For example, in another embodiment, The switch device 36 ′ can be a single infrared transceiver switch and is located below the trigger column 17 , so as to provide a one-way trigger function in which the user can press the roller 20 to lower the trigger switch device 36 ′.

In practical applications, the triggering design of the switch device of the present invention can also adopt a dual-pole induction triggering design. For example, please refer to FIG. 8, FIG. 9, and FIG. 10, and FIG. 8 is another implementation according to the present invention. An example is a partial perspective view of a mouse device 100 proposed. FIG. 9 is a schematic top view of the mouse device 100 in FIG. 8 when the scroll wheel 20 is deflected to the left, and FIG. 10 is the mouse in FIG. 8. A schematic top view of the device 100 when the scroll wheel 20 is deflected to the right, wherein in order to clearly show the internal components of the mouse device 100, the base 12 and the upper cover 14 are omitted in FIG. 8 and a circuit board 102 It is partially illustrated, and the elements mentioned in this embodiment and the above-mentioned embodiments have the same number, which means they have the same structure or function, and the related descriptions are not repeated here. In this embodiment, the mouse device 100 includes a base 12 , an upper cover 14 , a bearing base 16 , a scroll wheel 20 and a circuit board 102 . The circuit board 102 is disposed on the base 12 and has a switch device corresponding to the position of the second magnetic member 26 . 104, the switching device 104 can be a bipolar Hall sensor, and the second magnetic element 26 is a magnet, wherein the bipolar Hall magnetic sensor can pass through between itself and the dual magnetic poles of the magnet. The distance is different and the bipolar induction design of the voltage output is correspondingly generated to detect whether the second magnetic element 26 is left or right relative to the first magnetic element 24. As for the bipolar Hall magnetic field sensor The related description of the dual magnetic pole induction principle is common in the prior art, and will not be repeated here.

Through the above design, when the roller 20 is biased to the left by the lateral force f1, the bearing seat 16 will be deflected to the left relative to the first magnetic member 24 (it can be seen as being deflected in the clockwise direction in FIG. 9 ). During this process, it can be seen from FIG. 9 that a first magnetic pole end P1 (eg, N pole) of the second magnetic member 26 is relatively far away from the switching device 104 , and a second magnetic pole end P2 of the second magnetic member 26 ( Such as the S pole) is relatively close to the switch device 104, whereby the second magnetic member 26 is deflected to the left relative to the first magnetic member 24, causing the switch device 104 to be connected to the first magnetic pole portion P1 and the second magnetic pole portion P2 respectively. When the relative distance between them is changed, the second magnetic member 26 can trigger the switch device 104 to complete the corresponding input operation (eg, control the horizontal scroll bar of the window operation interface to move horizontally to the left). On the other hand, when the roller 20 is biased to the right by the lateral force f2, the bearing base 16 will be deflected to the right relative to the first magnetic member 24 (it can be seen as deflected in the counterclockwise direction in Fig. 10), here During the process, it can be seen from FIG. 10 that the first magnetic pole end P1 of the second magnetic member 26 is relatively close to the switch device 104, and the second magnetic pole end P2 of the second magnetic member 26 is relatively far away from the switching device 104, thereby , when the second magnetic member 26 is deflected to the left relative to the first magnetic member 24, causing the relative distances between the switching device 104 and the first magnetic pole end P1 and the second magnetic pole end P2 to change, respectively, the second magnetic The magnetic element 26 can trigger the switch device 104 to complete the corresponding input operation (eg, control the horizontal scroll bar of the window operation interface to move horizontally to the right).

It should be noted that, as can be seen from FIG. 8 , the scroll wheel pressing trigger design of the mouse device 100 adopts the optical trigger design of triggering the second switch 40 ′ by the trigger column 17 mentioned in the above-mentioned embodiment, but this is not the case. However, the present invention can also adopt a single-pole induction trigger design. For example, in another embodiment, the switching device can be a single-pole Hall magnetic field sensor and is located under the second magnetic element, and the second magnetic element The system can be a magnet, and the unipolar Hall magnetic field sensor can be triggered when the magnet approaches a certain distance. As for the description of the magnetic induction principle of the unipolar Hall magnetic field sensor, it is common in the prior art. This will not be repeated here. In this way, when the scroll wheel is pressed, the second magnetic member can be deflected downward toward the switch device to sense the trigger switch device, so as to complete the corresponding input operation (such as closing the browser tab, etc.). The above descriptions are only preferred embodiments of the present invention, and all equivalent changes and modifications made according to the scope of the patent application of the present invention shall fall within the scope of the present invention.
