Description

Mouse device

Technical Field

The present disclosure relates to a mouse device.

Background

At present, the mouse is a tool frequently used when people work and play games. There are generally two buttons on the front of the mouse and a scroll wheel located between the two buttons. When a certain operation window is displayed on a computer screen, a roller of the mouse is rolled to slide the page of the operation window, so that the required content can be found on the page more quickly and accurately.

However, in the conventional mouse, the rolling touch feeling and the installation tightness of the wheel are adjusted before the factory shipment, so that the rolling touch feeling of the wheel is not adjustable, and the hand feeling required by individual customers cannot be satisfied (for example, when the wheel rotates for one circle, the wheel can obtain different times of paragraph feeling and the page distance of the operation window, etc.), and the user needs to return to the operation system/or the console to adjust the rolling data of the wheel. In addition, as the use time increases, the rolling hand feeling of the roller wheel may be worse and worse, and the existing mouse does not provide an effective adjustment scheme for the phenomenon. In other words, the roller of the existing mouse cannot meet the increasing demand of people.

Therefore, how to provide a mouse device capable of solving the above problems is one of the problems that the industry needs to invest in research and development resources to solve.

The third magnetic part is not opposite to the first magnetic part when the base is located at the first position, and is opposite to the first magnetic part when the base is located at the second position. The magnetic force generated when the second magnetic part is opposite to the first magnetic part is different from the magnetic force generated when the third magnetic part is opposite to the first magnetic part.

In one or more embodiments of the present disclosure, the driving assembly further includes a first magnetic member and a second magnetic member. The first magnetic part is arranged on one side of the elastic sheet far away from the rotating shaft. The second magnetic part is arranged on the base and provided with a surface facing the elastic sheet. The first magnetic member is spaced from the surface by a first minimum distance when the base is located at the first position and by a second minimum distance when the base is located at the second position.

In one or more embodiments of the present disclosure, the surface is a smooth surface.

In one or more embodiments of the present disclosure, the elastic sheet has a first section and a second section connected to each other. The thickness of the first section is greater than the thickness of the second section. The first section is in contact with the rotating shaft. The driving assembly further comprises an abutting piece arranged on the base. The abutting piece abuts against the first section and the second section when the base is located at the first position and the second position respectively.

In one or more embodiments of the present disclosure, the driving assembly further includes a force application member. The force application member is arranged on the base and is configured to apply thrust to the abutting member when the abutting member abuts against the first section.

In one or more embodiments of the present disclosure, the elastic sheet further has a third section connected to the first section. The thickness of the first section is greater than the thickness of the third section. The driving assembly further comprises another abutting piece. The other abutting piece is arranged on the base. The other abutting piece abuts against the third section and the first section when the base is located at the first position and the second position respectively.

In one or more embodiments of the present disclosure, when the base is located at a third position between the first position and the second position relative to the bottom plate, the abutting member and the another abutting member abut against the second section and the third section, respectively.

In one or more embodiments of the present disclosure, the driving assembly further includes another force applying member. The other force applying piece is arranged on the base and is configured to apply other thrust to the other abutting piece when the other abutting piece abuts against the first section.

In one or more embodiments of the present disclosure, the another force applying member is a compression spring and contacts with the another abutting member.

In one or more embodiments of the present disclosure, the another abutting member and the another force applying member are two magnetic members that repel each other.

In one or more embodiments of the present disclosure, the driving assembly further includes an abutting member disposed on the base. The abutting piece abuts against the first contact point and the second contact point on the elastic sheet respectively when the base is located at the first position and the second position. The second contact point is closer to the rotation axis than the first contact point. The thickness of the elastic sheet is gradually increased from the first contact point to the second contact point.

In one or more embodiments of the present disclosure, the driving assembly further includes a force application member. The force application piece is arranged on the base and is configured to apply thrust to the abutting piece.

In one or more embodiments of the present disclosure, the urging member is a compression spring, and is in contact with the abutting member.

In one or more embodiments of the present disclosure, the base protrudes along a direction away from the bottom plate to form the receiving groove. The containing groove is configured to contain the magnetic piece or the force application piece.

In summary, in the mouse device of the present disclosure, when the base of the driving assembly moves to different positions relative to the bottom plate, the driving assembly can drive the elastic sheet to abut against the rotating shaft of the roller with different forces. Therefore, the moment when the roller is rotated can be effectively adjusted. In some embodiments, by increasing the number of the driving elements of the driving assembly, the driving assembly drives the elastic sheet to abut against the rotating shaft of the roller with different forces in a contact or non-contact manner when the base moves to a specific position relative to the bottom plate, thereby achieving multi-stage torque adjustment. In some embodiments, the elastic sheet or the driving element of the driving assembly has a specific shape, so that the driving assembly can immediately change the force of the elastic sheet abutting against the rotating shaft when the relative position of the base and the bottom plate is changed, thereby achieving stepless torque adjustment.

The foregoing has been provided merely to illustrate the problems, solutions to problems, and their efficacy, and the like that are intended to be solved by the present disclosure, and the details of which are set forth in the following description and the related drawings.

Detailed Description

Various embodiments of the present disclosure are disclosed in the drawings and, for purposes of clarity, numerous implementation details are set forth in the following description. It should be understood, however, that these implementation details should not be used to limit the disclosure. That is, in some embodiments of the disclosure, such practical details are not necessary. In addition, some prior art structures and elements are shown in the drawings in a simple schematic manner for the sake of simplifying the drawings.

Please refer to fig. 1 and fig. 2. Fig. 1 is a perspective view illustrating a mouse device 100 according to an embodiment of the present disclosure. Fig. 2 is a partial perspective view showing a part of elements of the mouse apparatus 100 in fig. 1. As shown in fig. 1 and fig. 2, in the present embodiment, the mouse device 100 includes a housing 110, a roller 120, an elastic sheet 130 and a driving element 140. The housing 110 includes a bottom plate 111, two supporting posts 112 and two fixing posts 113. The supporting posts 112 and the fixing posts 113 are disposed on the bottom plate 111. The roller 120 has a rotation shaft 121. The two ends of the shaft 121 are pivotally connected to the supporting posts 112, so that the roller 120 is rotatably disposed above the base plate 111. Two ends of the elastic piece 130 are respectively fixed to the fixing posts 113 so as to be located between the bottom plate 111 and the rotating shaft 121 and abut against the rotating shaft 121. The elastic plate 130 is fixed to the fixing post 113 by a screw locking method, but the disclosure is not limited thereto. The driving assembly 140 includes a base 141. The base 141 is movably disposed on the base plate 111. The driving assembly 140 is configured to drive the elastic pieces 130 to abut against the rotating shaft 121 with different forces when the base 141 is located at different positions relative to the bottom plate 111.

In some embodiments, as shown in fig. 2, the outer edge of the rotating shaft 121 has a tooth-shaped structure 121a. The elastic piece 130 has a convex portion 131 (see fig. 3A). The protrusions 131 are configured to abut the tooth-like structures 121a. Therefore, when the protrusion 131 abuts against the tooth-shaped structure 121a and the user rotates the roller 120 with his finger, the user can feel the feedback step feeling when the tooth-shaped structure 121a contacts with the protrusion 131.

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

Please refer to fig. 3A, fig. 3B, and fig. 3C. Fig. 3A is a partial cross-sectional view illustrating the mouse apparatus 100 in fig. 2, wherein the base 141 of the driving assembly 140 is located at a first position. Fig. 3B is another partial sectional view of the mouse apparatus 100 in fig. 2, wherein the base 141 of the driving assembly 140 is located at a third position. Fig. 3C is another partial cross-sectional view illustrating the mouse apparatus 100 in fig. 2, wherein the base 141 of the driving assembly 140 is located at the second position.

As shown in fig. 3A and 3C, in the present embodiment, the driving assembly 140 further includes a first magnetic element 142 and a second magnetic element 143. The first magnetic element 142 is disposed on a side of the elastic sheet 130 away from the rotating shaft 121. In some embodiments, the first magnetic element 142 can be assembled and fixed on the elastic sheet 130 by heat melting, adhesion (for example, glue, AB glue, hot melt glue, or double-sided glue), and the like, but the disclosure is not limited thereto. 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 a receiving 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 located at the first position, and is not opposite to the first magnetic member 142 when the base 141 is located at the second position and the third position. In some embodiments, a definition of "opposite" refers to a projection of one of the first magnetic element 142 and the second magnetic element 143 along a direction passing through the other of the first magnetic element 142 and the second magnetic element 143. In some embodiments, the direction is substantially perpendicular to the bottom plate 111, but the disclosure is not limited thereto.

As shown in fig. 3A and 3C, in the present embodiment, the driving assembly 140 further includes a third magnetic element 144. The third magnetic member 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 a receiving 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 located at the first position, and is opposite to the first magnetic member 142 when the base 141 is located at the second position. In some embodiments, the second magnetic element 143 and the third magnetic element 144 are disposed in the accommodating grooves 141c and 141d at intervals (i.e., a gap is formed between the second magnetic element 143 and the third magnetic element 144).

As shown in fig. 3B, in the present embodiment, when the base 141 moves to the third position relative to the bottom plate 111, the second magnetic member 143 and the third magnetic member 144 are not aligned with the first magnetic member 142 (i.e., are aligned with the gap between the second magnetic member 143 and the third magnetic member 144), so the force applied by the first magnetic member 142 to the elastic sheet 130 is very small and can be ignored, but the 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 sheet 130 and the tooth-shaped structure 121a are configured in a non-contact state, so that no falling feeling is generated when the roller 120 is rotated.

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

In some embodiments, the bottom end of the first magnetic element 142 is opposite to the top end of the third magnetic element 144 at the end with the same polarity, so that when the third magnetic element 144 is opposite to the first magnetic element 142, the two elements repel each other, and the elastic piece 130 is pushed upward by the first magnetic element 142 to increase the force of abutting against the rotating shaft 121. In other embodiments, the bottom end of the first magnetic element 142 is opposite to the top end of the third magnetic element 144, so that when the third magnetic element 144 is opposite to the first magnetic element 142, the two magnetic elements attract each other, and the elastic sheet 130 is pulled downward by the first magnetic element 142 to reduce the force abutting against the rotating shaft 121.

In the present embodiment, the magnetic force generated when the second magnetic element 143 opposes the first magnetic element 142 is different from the magnetic force generated when the third magnetic element 144 opposes the first magnetic element 142. As shown in fig. 3A, the top end of the second magnetic element 143 and the top end of the third magnetic element 144 are the same polarity end, and the size of the second magnetic element 143 is smaller than that of the third magnetic element 144, so that the two magnetic elements generate different magnetic forces when facing the first magnetic element 142. In other embodiments, the top end of the second magnetic element 143 and the top end of the third magnetic element 144 are opposite to each other, so that the two magnetic elements generate magnetic forces in different directions when facing the first magnetic element 142. Specifically, when the base 141 is located at the first position, the magnetic force generated by the first magnetic element 142 and the second magnetic element 143 drives the protrusion 131 to abut against the tooth-shaped structure 121a, so as to generate a paragraph feeling. When the base 141 is located at the second position, the magnetic force generated by the first magnetic element 142 and the third magnetic element 144 drives the protrusion 131 to abut against the tooth-shaped structure 121a, thereby generating a paragraph feeling. 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 the same polarity end. Therefore, the first magnetic element 142 can generate different degrees of magnetic force relative to the second magnetic element 143 or the third magnetic element 144 to change the force of the protrusion 131 abutting against the tooth-shaped structure 121a of the roller 120, so that the roller 120 can generate different segment senses when being operated and rotated.

With the above-mentioned structural configuration, the driving element 140 of the present embodiment can drive the elastic sheet 130 to abut against the rotating shaft 121 of the roller 120 with different forces in a non-contact manner when the base 141 moves to a specific position (e.g., the first position, the second position, and the third position) relative to the bottom plate 111, thereby achieving a multi-stage torque adjustment.

As shown in fig. 3A to 3C, in the present embodiment, the bottom plate 111 has a through hole 111a. The base 141 has a dial 141a. The dial 141a extends into the through hole 111a. Therefore, a user can conveniently move the base 141 of the driving assembly 140 to the first position, the second position and the third position relative to the bottom plate 111 by dialing the dial block 141a with a finger.

Referring to fig. 4, another partial perspective view of a part of the components of the mouse device 100 in fig. 1 is shown. As shown in fig. 4, in the present embodiment, the housing 110 further includes a positioning element 111b. The positioning element 111b is disposed on the bottom plate 111, and at least two positioning notches 111b1 and 111b2 are disposed on the sidewall of the positioning element 111b. The base 141 of the driving assembly 140 further includes a flexible member 141b. The flexible member 141b has a positioning bump 141b1. The positioning protrusions 141b1 movably abut the sidewalls of the positioning member 111b. When the base 141 moves to the first position relative to the bottom plate 111, the positioning protrusion 141b1 is engaged with the positioning recess 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 protrusions 141b1 engage 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 form a single component, i.e., they are integrally formed.

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

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

As shown in fig. 5A to fig. 5C, in the present embodiment, the mouse device 200 includes the housing 110, the roller 120, the elastic sheet 230 and the driving assembly 240, wherein the housing 110 and the roller 120 are the same as the embodiment shown in fig. 3A, and therefore, reference may be made to the foregoing description and further description thereof will not be repeated. The present embodiment is modified with respect to the elastic sheet 230 and the driving assembly 240.

Specifically, in the present 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 and third sections 232, 233. The first segment 231 is in contact with the rotation shaft 121 of the roller 120. The protrusion 131 is located at the first section 231. Specifically, the first section 231 is located below the rotating shaft 121. The protrusion 131 is formed on the first section 231 and configured to abut against the tooth-shaped 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 241a and 241b. The driving assembly 240 further includes abutting members 242a,242b and force applying members 243a,243 b. The biasing member 243a is disposed in the accommodating groove 241 a. The abutting piece 242a movably engages with the inner wall of the receiving groove 241a and protrudes out of the receiving groove 241 a. The urging member 243a abuts between the bottom end of the accommodating groove 241a and the abutting member 242 a. Similarly, the force applying member 243b is disposed in the accommodating groove 241b. The abutting piece 242b movably engages with the inner wall of the receiving groove 241b and protrudes out of the receiving groove 241b. The urging member 243b abuts between the bottom end of the accommodating groove 241b and the abutting member 242 b. In the present embodiment, the biasing members 243a and 243b are compression springs and have different elastic coefficients.

It should be noted that the abutting piece 242a abuts the first section 231 and the second section 232 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 that of the second section 232, the compression amount of the force applying element 243a is increased when the abutting element 242a moves from the second section 232 to the first section 231, so that the elastic piece 230 is pushed upwards by the abutting element 242a to increase the force of abutting against the rotating shaft 121. Similarly, the abutting piece 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 that of the third section 233, the compression amount of the force applying element 243b is increased when the abutting element 242b moves from the third section 233 to the first section 231, so that the elastic sheet 230 is pushed upward by the abutting element 242b to increase the force of abutting against the rotating shaft 121.

As shown in fig. 5B, in the present embodiment, when the base 241 moves to the third position between the first position and the second position relative to the bottom plate 111, the abutting pieces 242a and 242B abut against the second section 232 and the third section 233, respectively, so that the urging force of the abutting pieces 242a and 242B on the elastic piece 230 is very small and can be ignored, but the 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 sheet 230 and the tooth-shaped structure 121a are configured in a non-contact state, so that no falling feeling is generated when the roller 120 is rotated.

With the above-mentioned structural configuration, the driving element 240 of the present embodiment can drive the elastic sheet 230 to abut against the rotating shaft 121 of the roller 120 with different forces in a contact manner when the base 241 moves to a specific position (e.g., the first position, the second position, and the third position) relative to the bottom plate 111, thereby achieving a multi-stage torque adjustment.

Referring to fig. 6, a partial cross-sectional view of a mouse device 300 according to another embodiment of the disclosure is shown, wherein the base 241 of the driving assembly 340 is located at a first position. As shown in fig. 6, in the present embodiment, the mouse device 300 includes a housing 110, a roller 120, an elastic sheet 230 and a driving assembly 340, wherein the housing 110, the roller 120 and the elastic sheet 230 are the same as the embodiment shown in fig. 5A, so that reference can be made to the related descriptions, which will not be repeated herein. The present embodiment is modified with respect to the driving assembly 340. Specifically, in the present embodiment, the driving element 340 includes a base 241, abutting elements 342a,342b and force applying elements 343a,343b, wherein the base 241 is the same as the embodiment shown in fig. 5A, so that the related descriptions can be referred to and will not be repeated herein. The abutting member 342a and the force applying member 343a in this embodiment are two mutually repulsive magnetic members, and the abutting member 342b and the force applying member 343b are two mutually repulsive magnetic members. The size of the force application member 343a is smaller than that of the force application member 343b, so that they generate different magnetic forces with the abutting members 342a,342b, respectively. With the above-mentioned structure configuration, the driving assembly 340 of the present embodiment can also drive the elastic sheet 230 to abut against the rotating shaft 121 of the roller 120 with different forces in a contact manner when the base 241 moves to a specific position (refer to fig. 5A to 5C) relative to the bottom plate 111, thereby achieving multi-stage torque adjustment.

Please refer to fig. 7A and fig. 7B. Fig. 7A is a partial sectional view illustrating a mouse apparatus 400 according to another embodiment of the present disclosure, in which a base 441 of a driving assembly 440 is located at a first position. Fig. 7B is another partial cross-sectional view illustrating the mouse apparatus 400 in fig. 7A, wherein the base 441 of the driving assembly 440 is located at a second position. As shown in fig. 7A and 7B, in the present embodiment, the mouse device 400 includes a housing 110, a roller 120, an elastic sheet 430 and a driving assembly 440, wherein the housing 110 and the roller 120 are the same as the embodiment shown in fig. 3A, so that reference can be made to the related descriptions, which will not be repeated herein. The present embodiment is modified for the elastic piece 430 and the driving assembly 440.

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

As shown in fig. 7A, the abutting piece 442 abuts against the first contact point 431 on the elastic sheet 430 when the base 441 is located at the first position. As shown in fig. 7B, the abutting piece 442 abuts against the second contact point 432 on the elastic sheet 430 when the base 441 is located at the second position. The second contact point 432 is closer to the rotation shaft 121 than the first contact point 431. The thickness of the elastic piece 430 increases from the first contact point 431 to the second contact point 432. Therefore, the compression amount of the force application member 443 gradually increases during the movement of the abutting member 442 from the first contact point 431 to the second contact point 432, so that the elastic piece 430 is pushed upward by the abutting member 442 to gradually increase the force of the protrusion 131 abutting against the tooth-shaped structure 121a of the rotating shaft 121.

With the above-mentioned structure configuration, the driving assembly 440 of the present embodiment can immediately change the force of the elastic piece 430 contacting the rotating shaft 121 by contacting when the base 441 changes the relative position with respect to the bottom plate 111, thereby achieving stepless torque adjustment.

In some embodiments, the abutting element 442 and the force applying element 443 shown in fig. 7A can be replaced by two magnetic elements that repel each other, so as to achieve the aforementioned stepless torque adjustment.

Please refer to fig. 8A and fig. 8B. Fig. 8A is a partial cross-sectional view illustrating a mouse apparatus 500 according to another embodiment of the present disclosure, in which a base 541 of an actuating assembly 540 is located at a first position. Fig. 8B is another partial cross-sectional view of the mouse apparatus 500 in fig. 8A, wherein the base 541 of the driving assembly 540 is located at the second position. As shown in fig. 8A and 8B, in the present embodiment, the mouse device 500 includes the housing 110, the roller 120, the elastic sheet 130 and the driving assembly 540, wherein the housing 110, the roller 120 and the elastic sheet 130 are the same as the embodiment shown in fig. 3A, so that reference can be made to the foregoing description, which will not be repeated herein. The present embodiment is modified with respect to the driving assembly 540.

Specifically, in the present embodiment, the driving assembly 540 further includes a first magnetic element 142 and a second magnetic element 543. The first magnetic element 142 is disposed on a side of the elastic sheet 130 away from the rotating shaft 121. The second magnetic member 543 is disposed on the base 541, and has a surface 543a facing the elastic sheet 130. The first magnetic member 142 is separated from the surface 543a by a first minimum distance D1 when the substrate 541 is located at the first position, and by a second minimum distance D2 when the substrate 541 is located at the second position. As shown in fig. 8A and 8B, since the second minimum distance D2 is smaller than the first minimum distance D1, the magnetic force generated by the first magnetic component 142 and the second magnetic component 543 when the base 541 is located at the first position is smaller than the magnetic force generated when the base 541 is located at the second position.

In some embodiments, the bottom end of the first magnetic element 142 is opposite to the top end of the second magnetic element 543 with the same polarity, so that the bottom end and the top end repel each other, and the elastic piece 130 is pushed upward by the first magnetic element 142 to increase the force of contacting the rotating shaft 121. In other embodiments, the bottom end of the first magnetic member 142 and the top end of the second magnetic member 543 are opposite to each other, so that the two are attracted to each other, and the elastic sheet 130 is pulled downward by the first magnetic member 142 to reduce the force against the rotating shaft 121.

With the above-mentioned structure configuration, the driving assembly 540 of the present embodiment can immediately change the force of the elastic piece 130 contacting the rotating shaft 121 in a non-contact manner when the relative position of the base 541 with respect to the bottom plate 111 changes, thereby achieving stepless torque adjustment.

In some embodiments, as shown in fig. 8A, the surface 543a of the second magnetic member 543 is a smooth surface inclined with respect to the bottom plate 111, but the disclosure is not limited thereto. In practical applications, the surface 543a of the second magnetic member 543 can be elastically adjusted according to actual requirements.

As will be apparent from the above detailed description of the embodiments of the present disclosure, in the mouse device of the present disclosure, when the base of the driving assembly moves to different positions relative to the bottom plate, the driving assembly can drive the elastic sheet to abut against the rotating shaft of the roller with different forces. Therefore, the moment when the roller is rotated can be effectively adjusted. In some embodiments, by increasing the number of the driving elements of the driving assembly, the driving assembly drives the elastic sheet to abut against the rotating shaft of the roller with different forces in a contact or non-contact manner when the base moves to a specific position relative to the bottom plate, thereby achieving multi-stage torque adjustment. In some embodiments, the elastic sheet or the driving element of the driving assembly has a specific shape, so that the driving assembly can immediately change the force of the elastic sheet abutting against the rotating shaft when the relative position of the base and the bottom plate is changed, thereby achieving stepless torque adjustment.

Although the present disclosure has been described with reference to the above embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the present disclosure, and therefore, the scope of the present disclosure should be determined only by the appended claims.
