In some embodiments, the housing 110 may include only one fixing post 113 . And only one end of the elastic sheet 130 is fixed to the fixing post 113 . That is, the fixing column 113 and the elastic piece 130 can form a structure similar to a cantilever.

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 component 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 element 140 is located at the 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 element 140 is located at the second position.

As shown in FIGS. 3A and 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 sheet 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 hot-melting, adhesion (eg, glue, AB glue, hot-melt adhesive or double-sided tape), but the present disclosure does not use this method. limited. The second magnetic member 143 is disposed on the base 141 . The base 141 has an accommodating groove 141c. Specifically, the base 141 protrudes in a direction away from the bottom plate 111 to form an accommodating groove 141c. The second magnetic member 143 is disposed in the accommodating groove 141c. The second magnetic member 143 is opposite to the first magnetic member 142 when the base 141 is at the first position, and is not opposite to the first magnetic member 142 when the base 141 is at the second position and the third position. In some embodiments, one definition of the aforementioned “opposite” refers to the projection of one of the first magnetic element 142 and the second magnetic element 143 along a direction passing through the first magnetic element 142 and the second magnetic element 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 component 140 further includes a third magnetic member 144 . The third magnetic member 144 is disposed on the base 141 . The base 141 further has an accommodating groove 141d. Specifically, the base 141 protrudes in a direction away from the bottom plate 111 to form an accommodating groove 141d. The third magnetic member 144 is disposed in the accommodating groove 141d. The third magnetic member 144 is not opposite to the first magnetic member 142 when the base 141 is at the first position, and is opposite to the first magnetic member 142 when the base 141 is at the second position. In some embodiments, the second magnetic element 143 and the third magnetic element 144 are disposed in the accommodating grooves 141 c and 141 d at intervals (ie, there is a gap between the second magnetic element 143 and the third magnetic element 144 ).

As shown in FIG. 3B , in this embodiment, when the base 141 moves to the third position relative to the bottom plate 111 , neither the second magnetic part 143 nor the third magnetic part 144 is aligned with the first magnetic part 142 (ie, , the gap between the second magnetic member 143 and the third magnetic member 144 is aligned), so the force exerted by the first magnetic member 142 on the elastic sheet 130 is very small and can be ignored, but the disclosure is not limited to this. In some embodiments, when the base 141 moves to the third position relative to the bottom plate 111 , the elastic piece 130 and the toothed structure 121 a are configured to be in a non-contact state, so that the roller 120 does not have a sense of paragraph when rotating.

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

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

In this embodiment, the magnetic force generated when the second magnetic element 143 is opposed to the first magnetic element 142 is different from the magnetic force generated when the third magnetic element 144 is opposed to the first magnetic element 142 . As shown in FIG. 3A , the top end of the second magnetic member 143 and the top end of the third magnetic member 144 are the same polar ends, and the size of the second magnetic member 143 is smaller than that of the third magnetic member 144 , so the two are in the same polarity as the third magnetic member 144 . When a magnetic element 142 is opposed to each other, magnetic forces of different magnitudes are generated. In other embodiments, the top end of the second magnetic member 143 and the top end of the third magnetic member 144 are opposite polar ends, so when they are opposite to the first magnetic member 142 , magnetic forces in different directions are generated. 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 opposing each other will drive the protruding portion 131 to abut against the tooth-like structure 121 a, thereby creating a sense of paragraph. When the base 141 is located at the second position, the magnetic force generated by the first magnetic member 142 and the third magnetic member 144 opposing each other will drive the protruding portion 131 to abut against the tooth-like structure 121a, thereby generating a sense of paragraph. Since the size of the third magnetic element 144 is larger than that of the second magnetic element 143 , the top end of the third magnetic element 144 and the top end of the second magnetic element 143 are of the same polarity. Thereby, the first magnetic member 142 can generate different degrees of magnetic force relative to the second magnetic member 143 or the third magnetic member 144 to change the force of the protrusion 131 abutting against the toothed structure 121 a of the roller 120 , so that the roller 120 When it is rotated by operation, it will produce a different sense of paragraph.

With the aforementioned structural configuration, the driving component 140 of this embodiment can be driven in a non-contact manner when the base 141 moves to a specific position relative to the base plate 111 (eg, the aforementioned first position, second position and third position). The elastic sheet 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 FIGS. 3A to 3C, in this embodiment, the bottom plate 111 has a through hole 111a. The base 141 has a dial 141a. The dial block 141a extends into the through hole 111a. Thereby, the user can conveniently move the base 141 of the driving assembly 140 relative to the bottom plate 111 to the first position, the second position and the third position by turning the toggle block 141a with fingers.

Please refer to FIG. 4 , which is another partial perspective view illustrating some elements of the mouse device 100 in FIG. 1 . As shown in FIG. 4, in this embodiment, the housing 110 further includes a positioning member 111b. The positioning member 111b is disposed on the bottom plate 111, and at least two positioning notches 111b1 and 111b2 are disposed on the side wall of the positioning member 111b. The base 141 of the driving assembly 140 further includes a flexible member 141b. The flexible member 141b has positioning bumps 141b1. The positioning bump 141b1 is movably abutted against the side wall of the positioning member 111b. When the base 141 moves to the first position relative to the base plate 111 , the positioning protrusions 141b1 are engaged with the positioning recesses 111b1 , so that the base 141 is positioned at the first position relative to the base plate 111 . When the base 141 moves to the second position relative to the bottom plate 111 , the positioning protrusions 141b1 are engaged with the positioning recesses 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 may further have a third positioning recess between the positioning recesses 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, the two are integrally formed.

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

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

As shown in FIGS. 5A to 5C , in this embodiment, the mouse device 200 includes a housing 110 , a roller 120 , an elastic sheet 230 and a driving component 240 , wherein the housing 110 and the roller 120 are the same as those shown in FIG. 3A . Since the above-mentioned related descriptions can be referred to, detailed descriptions are omitted here. This embodiment is modified for the elastic sheet 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 that 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-like structure 121a. In addition, the base 241 of the driving assembly 240 has accommodating grooves 241a and 241b. Specifically, the base 241 protrudes in a direction away from the bottom plate 111 to form accommodating grooves 241 a and 241 b. The driving assembly 240 further includes abutting members 242a, 242b and force-applying members 243a, 243b. The force applying member 243a is disposed in the accommodating 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 force applying member 243a abuts between the bottom end of the accommodating groove 241a and the abutting member 242a. Similarly, the force applying member 243b is disposed in the accommodating 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 force applying member 243b abuts between the bottom end of the accommodating groove 241b and the abutting member 242b. In this embodiment, the force-applying members 243a and 243b are compression springs and have different elastic coefficients.

Since the thickness of the first section 231 is greater than the thickness of the second section 232, the compression amount of the force applying member 243a increases when the abutting member 242a moves from the second section 232 to the first section 231, thereby making the elasticity The piece 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 the third section 233 and the first section 231 when the base 241 is located at the first position (see FIG. 5A ) and the second position (see FIG. 5C ), respectively. Since the thickness of the first section 231 is greater than the thickness of the third section 233, the compression amount of the force applying member 243b increases when the abutting member 242b moves from the third section 233 to the first section 231, thereby making the elasticity The piece 230 is pushed upward by the abutting member 242b 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 242 a and 242 b respectively abut against the second area The segment 232 and the third segment 233, therefore, the force exerted by the abutting members 242a, 242b on the elastic sheet 230 is very small and can be ignored, but the present disclosure is not limited to this. In some embodiments, when the base 241 moves to the third position relative to the bottom plate 111 , the elastic piece 230 and the toothed structure 121 a are configured to be in a non-contact state, so that the roller 120 does not have a sense of paragraph when rotating.

With the aforementioned structural configuration, the driving component 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 (eg, the aforementioned first position, second position and third position). The sheet 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 of 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.

Since the above-mentioned related descriptions can be referred to, detailed descriptions are omitted here. This embodiment is modified for the drive assembly 340 . Specifically, in this embodiment, the driving assembly 340 includes a base 241, abutting members 342a, 342b, and force-applying members 343a, 343b, wherein the base 241 is the same as the embodiment shown in FIG. 5A, so refer to The foregoing related descriptions will not be repeated here. In this embodiment, the abutting member 342a and the force applying member 343a are two magnetic members that repel each other, and the abutting member 342b and the force applying member 343b are two magnetic members 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 aforementioned structure and configuration, the driving component 340 of this embodiment can also drive the elastic sheet 230 through contact when the base 241 moves to a specific position relative to the bottom plate 111 (refer to FIG. 5A to FIG. 5C for cooperation). The force abuts against the rotating shaft 121 of the roller 120 , so as to achieve multi-stage torque adjustment.

Since the above-mentioned related descriptions can be referred to, detailed descriptions are omitted here. This embodiment is modified for the elastic sheet 430 and the driving assembly 440 .

Specifically, in this embodiment, the base 441 of the driving assembly 440 has an accommodating groove 441a. The driving assembly 440 further includes an abutting member 442 and a force applying member 443 . The force applying member 443 is disposed in the accommodating groove 441a. The abutting member 442 movably engages with the inner wall of the accommodating groove 441a and protrudes out of the accommodating groove 441a. The force applying member 443 abuts between the bottom end of the accommodating groove 441 a and the abutting member 442 . In this embodiment, the urging 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 in 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 in the second position. The second contact point 432 is closer to the rotating shaft 121 than the first contact point 431 .
