Please refer to Figure 3A, Figure 3B and Figure 3C. FIG. 3A is a partial cross-sectional view of the mouse device 100 in FIG. 2 , wherein the base 141 of the driving unit 140 is located at the first position. FIG. 3B is another partial cross-sectional view of the mouse device 100 in FIG. 2 , wherein the base 141 of the driving unit 140 is located at a third position. FIG. 3C is another partial cross-sectional view of the mouse device 100 in FIG. 2 , wherein the base 141 of the driving unit 140 is located at the second position.

As shown in FIG. 3A and FIG. 3C , in this embodiment, the driving assembly 140 further includes a first magnetic member 142 and a second magnetic member 143 . The first magnetic member 142 is disposed on a side of the elastic piece 130 away from the rotating shaft 121 . In some embodiments, the first magnetic member 142 can be assembled and fixed on the elastic sheet 130 by means of thermal melting, adhesion (for example, glue, AB glue, hot melt adhesive or double-sided tape), but this disclosure does not mean that limit. The second magnetic member 143 is disposed on the base 141 . The base 141 has a receiving groove 141c. Specifically, the base 141 protrudes along a direction away from the bottom plate 111 to form an accommodating groove 141c. The second magnetic member 143 is disposed in the receiving groove 141c. The second magnetic part 143 is opposite to the first magnetic part 142 when the base 141 is at the first position, and is not opposite to the first magnetic part 142 when the base 141 is at the second position and the third position. In some embodiments, a definition of the aforesaid “opposite” refers to the projection of one of the first magnetic member 142 and the second magnetic member 143 along a direction through the first magnetic member 142 and the second magnetic member 143 the other. In some embodiments, the aforementioned direction is substantially perpendicular to the bottom plate 111 , but the present disclosure is not limited thereto.

As shown in FIG. 3A and FIG. 3C , in this embodiment, the driving assembly 140 further includes a third magnetic member 144 . The third magnetic element 144 is disposed on the base 141 . The base 141 further has a receiving groove 141d. Specifically, the base 141 protrudes along a direction away from the bottom plate 111 to form an accommodating groove 141d. The third magnetic member 144 is disposed in the receiving groove 141d. The third magnetic part 144 is not opposite to the first magnetic part 142 when the base 141 is at the first position, and is opposite to the first magnetic part 142 when the base 141 is at the second position. In some embodiments, the second magnetic component 143 and the third magnetic component 144 are spaced apart in the accommodating grooves 141c and 141d (that is, there is a gap between the second magnetic component 143 and the third magnetic component 144 ).

As shown in Figure 3B, in this embodiment, when the base 141 moves to the third position relative to the bottom plate 111, the second magnetic piece 143 and the third magnetic piece 144 are not aligned with the first magnetic piece 142 (that is, , aligning the gap between the second magnetic member 143 and the third magnetic member 144 ), so the force exerted by the first magnetic member 142 on the elastic sheet 130 is very small and negligible, but the present disclosure is not limited thereto. In some embodiments, when the base 141 moves to the third position relative to the bottom plate 111 , the elastic piece 130 and the tooth-shaped structure 121 a are not in contact with each other, so there is no step feeling when the roller 120 is rotated.

In some embodiments, the bottom end of the first magnetic member 142 is opposite to the top end of the second magnetic member 143 with the same polarity, so when the second magnetic member 143 is opposite to the first magnetic member 142, the two will repel each other. Furthermore, the elastic piece 130 is pushed upward by the first magnetic member 142 to increase the strength of abutting against the rotating shaft 121 . In some other embodiments, the bottom end of the first magnetic piece 142 is opposite to the top end of the second magnetic piece 143 , so when the second magnetic piece 143 is opposite to the first magnetic piece 142 , the two will interact with each other. Attraction, so that the elastic piece 130 is pulled downward by the first magnetic member 142 to reduce the force against the rotating shaft 121 .

In some embodiments, the bottom end of the first magnetic member 142 is opposite to the top end of the third magnetic member 144 with the same polarity. Therefore, when the third magnetic member 144 is opposite to the first magnetic member 142, the two will repel each other. Furthermore, the elastic piece 130 is pushed upward by the first magnetic member 142 to increase the strength of abutting against the rotating shaft 121 . In some other embodiments, the bottom end of the first magnetic member 142 is opposite to the top end of the third magnetic member 144, so when the third magnetic member 144 and the first magnetic member 142 face each other, the two will be opposite to each other. Attraction, so that the elastic piece 130 is pulled downward by the first magnetic member 142 to reduce the force against the rotating shaft 121 .

In this embodiment, the magnetic force generated when the second magnetic member 143 faces the first magnetic member 142 is different from the magnetic force generated when the third magnetic member 144 faces the first magnetic member 142 . As shown in FIG. 3A, the top end of the second magnetic piece 143 and the top end of the third magnetic piece 144 are ends of the same polarity, and the size of the second magnetic piece 143 is smaller than the size of the third magnetic piece 144. When a magnetic piece 142 faces each other, it will generate magnetic forces of different magnitudes. In other embodiments, the top end of the second magnetic piece 143 and the top end of the third magnetic piece 144 are ends with different polarities, so they generate magnetic forces in different directions when facing the first magnetic piece 142 . Specifically, when the base 141 is at the first position, the magnetic force generated by the first magnetic member 142 and the second magnetic member 143 will drive the protrusion 131 to abut against the tooth-shaped structure 121a, thereby creating a sense of step. When the base 141 is at the second position, the magnetic force generated by the first magnetic part 142 and the third magnetic part 144 will drive the protruding part 131 to abut against the tooth-shaped structure 121a, thereby creating a sense of step. Since the size of the third magnetic part 144 is larger than that of the second magnetic part 143 , and the top of the third magnetic part 144 and the top of the second magnetic part 143 have the same polarity. Thereby, the first magnetic part 142 can generate different degrees of magnetic force relative to the second magnetic part 143 or the third magnetic part 144, so as to change the strength of the protruding part 131 abutting against the toothed structure 121a of the roller 120, so that the roller 120 When it is operated and turned, it will produce different sense of paragraph.

With the aforementioned structural configuration, the drive unit 140 of this embodiment can be driven in a non-contact manner when the base 141 moves to a specific position relative to the bottom plate 111 (for example, the aforementioned first position, second position and third position). The elastic piece 130 abuts against the rotating shaft 121 of the roller 120 with different forces, so as to achieve multi-stage torque adjustment.

As shown in FIG. 3A to FIG. 3C , in this embodiment, the bottom plate 111 has a through hole 111 a. The base 141 has a dial 141a. The shifting block 141a extends into the through hole 111a. Thereby, the user can conveniently move the base 141 of the driving component 140 to the first position, the second position and the third position relative to the bottom plate 111 by moving the dial 141a with fingers.

Please refer to FIG. 4 , which is another partial perspective view illustrating some components of the mouse device 100 in FIG. 1 . As shown in FIG. 4 , in this embodiment, the casing 110 further includes a positioning member 111b. The positioning component 111b is disposed on the bottom plate 111, and at least two positioning notches 111b1, 111b2 are disposed on the sidewall of the positioning component 111b. The base 141 of the driving assembly 140 further includes a flexible member 141b. The flexible member 141b has a positioning protrusion 141b1. The positioning protrusion 141b1 is movably abutting against the sidewall of the positioning member 111b. When the base 141 moves to the first position relative to the bottom plate 111 , the positioning protrusion 141b1 engages with the positioning notch 111b1 , so that the base 141 is positioned at the first position relative to the bottom plate 111 . When the base 141 moves to the second position relative to the bottom plate 111 , the positioning protrusion 141b1 engages with the positioning notch 111b2 , so that the base 141 is positioned at the second position relative to the bottom plate 111 . In some embodiments, the sidewall of the positioning member 111b further has a third positioning notch between the positioning notches 111b1 and 111b2 , so that the base 141 can be positioned at a third position relative to the bottom plate 111 . In some embodiments, the positioning member 111b and the bottom plate 111 constitute a single component, that is, they are integrally formed.

As shown in FIG. 4 , in this embodiment, the casing 110 further includes a plurality of stoppers 111c. The stopper 111 c is disposed above the bottom plate 111 and stops on a side of the base 141 away from the bottom plate 111 , so as to prevent the base 141 from detaching from the bottom plate 111 .

Please refer to Figure 5A, Figure 5B and Figure 5C. FIG. 5A is a partial cross-sectional view illustrating a mouse device 200 according to another embodiment of the present disclosure, wherein the base 241 of the driving unit 240 is located at the first position. FIG. 5B is another partial cross-sectional view of the mouse device 200 shown in FIG. 5A , wherein the base 241 of the driving unit 240 is located at the third position. FIG. 5C is another partial cross-sectional view of the mouse device 200 shown in FIG. 5A , wherein the base 241 of the driving unit 240 is located at the second position.

As shown in Figures 5A to 5C, in this embodiment, the mouse device 200 includes a housing 110, a roller 120, an elastic piece 230, and a drive assembly 240, wherein the housing 110 and the roller 120 are the same as those shown in Figure 3A. For the implementation manner shown, reference may be made to the above-mentioned relevant descriptions, and details are not repeated here. This embodiment is modified for the elastic piece 230 and the driving assembly 240 .

Specifically, in this embodiment, the elastic sheet 230 has a first section 231 , a second section 232 and a third section 233 . The first section 231 is connected between the second section 232 and the third section 233 . The thickness of the first section 231 is greater than the thickness of the second section 232 and the third section 233 . The first section 231 is in contact with the rotating shaft 121 of the roller 120 . The raised portion 131 is located in the first section 231 . Specifically, the first section 231 is located below the rotating shaft 121 . The protruding portion 131 is formed on the first section 231 and configured to abut against the tooth structure 121a. In addition, the base 241 of the driving assembly 240 has receiving grooves 241a, 241b. Specifically, the base 241 protrudes along a direction away from the bottom plate 111 to form accommodating grooves 241a, 241b. The driving assembly 240 further includes abutting pieces 242a, 242b and force applying pieces 243a, 243b. The forcing member 243a is disposed in the receiving groove 241a. The abutting member 242a is movably engaged with the inner wall of the accommodating groove 241a, and protrudes out of the accommodating groove 241a. The forcing member 243a abuts between the bottom end of the accommodating groove 241a and the abutting member 242a. Similarly, the forcing member 243b is disposed in the receiving groove 241b. The abutting member 242b is movably engaged with the inner wall of the accommodating groove 241b, and protrudes out of the accommodating groove 241b. The forcing member 243b abuts between the bottom end of the accommodating groove 241b and the abutting member 242b. In this embodiment, the forcing members 243a and 243b are compression springs with different elastic constants.

It should be noted that, when the base 241 is located at the first position (see FIG. 5A ) and the second position (see FIG. 5C ), the abutting member 242 abuts against the first section 231 and the second section 232 respectively. Since the thickness of the first section 231 is greater than the thickness of the second section 232, the amount of compression of the force applying member 243a will increase when the abutting member 242a moves from the second section 232 to the first section 231, thereby making the elasticity The sheet 230 is pushed upward by the abutting member 242 a to increase the force of abutting against the rotating shaft 121 . Similarly, the abutting member 242b abuts against the third segment 233 and the first segment 231 respectively when the base 241 is located at the first position (see FIG. 5A ) and the second position (see FIG. 5C ). Since the thickness of the first section 231 is greater than the thickness of the third section 233, the amount of compression of the force applying member 243b will increase when the abutting member 242b moves from the third section 233 to the first section 231, thereby making the elasticity The sheet 230 is pushed upward by the abutting member 242 b to increase the force of abutting against the rotating shaft 121 .

As shown in FIG. 5B, in this embodiment, when the base 241 moves relative to the bottom plate 111 to a third position between the first position and the second position, the abutting members 242a, 242b respectively abut against the second area The section 232 and the third section 233 , therefore, the abutting pieces 242 a , 242 b exert very little force on the elastic piece 230 and can be ignored, but the present disclosure is not limited thereto. In some embodiments, when the base 241 moves to the third position relative to the bottom plate 111 , the elastic piece 230 and the tooth-like structure 121 a are not in contact with each other, so there is no step feeling when the roller 120 is rotated.

With the above-mentioned structural configuration, the drive unit 240 of this embodiment can drive the elasticity through contact when the base 241 moves to a specific position relative to the bottom plate 111 (for example, the aforementioned first position, second position and third position). The piece 230 abuts against the rotating shaft 121 of the roller 120 with different forces, so as to achieve multi-stage torque adjustment.

Please refer to FIG. 6 , which is a partial cross-sectional view illustrating a mouse device 300 according to another embodiment of the present disclosure, wherein the base 241 of the driving component 340 is located at the first position. As shown in FIG. 6, in this embodiment, the mouse device 300 includes a casing 110, a roller 120, an elastic piece 230, and a drive assembly 340, wherein the casing 110, the roller 120, and the elastic piece 230 are the same as those shown in FIG. 5A. For the implementation manner shown, reference may be made to the above-mentioned relevant descriptions, and details are not repeated here. This embodiment is modified for the driving assembly 340 . Specifically, in this embodiment, the driving assembly 340 includes a base 241, abutment members 342a, 342b, and force application members 343a, 343b, wherein the base 241 is the same as the embodiment shown in Figure 5A, so reference can be made to The aforementioned relevant descriptions will not be repeated here. In this embodiment, the abutting piece 342a and the force application piece 343a are two magnetic pieces that repel each other, and the abutment piece 342b and the force application piece 343b are two magnetic pieces that repel each other. The size of the force applying member 343a is smaller than that of the force applying member 343b, so the two generate magnetic forces of different magnitudes with the abutting members 342a and 342b respectively. With the above-mentioned structural configuration, the drive assembly 340 of this embodiment can also drive the elastic piece 230 in different ways through contact when the base 241 moves to a specific position relative to the bottom plate 111 (see Figures 5A to 5C). The force abuts against the rotating shaft 121 of the roller 120 to achieve multi-stage torque adjustment.

Please refer to Figure 7A and Figure 7B. FIG. 7A is a partial cross-sectional view illustrating a mouse device 400 according to another embodiment of the present disclosure, wherein the base 441 of the driving unit 440 is located at the first position. FIG. 7B is another partial cross-sectional view of the mouse device 400 shown in FIG. 7A , wherein the base 441 of the driving unit 440 is located at the second position. As shown in FIG. 7A and FIG. 7B, in this embodiment, the mouse device 400 includes a housing 110, a roller 120, an elastic piece 430, and a drive assembly 440, wherein the housing 110 and the roller 120 are the same as those shown in FIG. 3A For the implementation manner shown, reference may be made to the above-mentioned relevant descriptions, and details are not repeated here. This embodiment is modified for the elastic piece 430 and the driving assembly 440 .

Specifically, in this embodiment, the base 441 of the driving assembly 440 has a receiving groove 441a. The driving assembly 440 further includes an abutting component 442 and a force applying component 443 . The forcing member 443 is disposed in the receiving groove 441a. The abutting member 442 is movably engaged with the inner wall of the receiving groove 441a, and protrudes out of the receiving groove 441a. The forcing member 443 abuts between the bottom end of the accommodating groove 441 a and the abutting member 442 . In this embodiment, the forcing member 443 is a compression spring.

As shown in FIG. 7A , the abutting member 442 abuts against the first contact point 431 on the elastic piece 430 when the base 441 is at the first position. As shown in FIG. 7B , the abutting member 442 abuts against the second contact point 432 on the elastic piece 430 when the base 441 is located at the second position. The second contact point 432 is closer to the rotating shaft 121 than the first contact point 431 . The thickness of the elastic sheet 430 gradually increases from the first contact point 431 to the second contact point 432 . Therefore, the compression amount of the force applying member 443 will gradually increase during the movement of the abutting member 442 from the first contact point 431 to the second contact point 432, so that the elastic sheet 430 is pushed upward by the abutting member 442 to gradually increase the convexity.
