The drawings in the present application are for illustrative purposes only and are not intended to be drawn to scale. The following embodiments will further explain the related art of the present application in detail, but the disclosure is not intended to limit the scope of the present application.

It will be understood that, although the terms first, second, third, etc. may be used herein to describe various elements or signals, these elements or signals should not be limited by these terms. These terms are used primarily to distinguish one element from another element or from one signal to another signal. In addition, the term "or" as used herein should be taken to include any one or combination of more of the associated listed items as the case may be.

First embodiment

Referring to fig. 1 and 2, a first embodiment of the present application provides a variable resistance device S, including: a first conductive member 1, a second conductive member 2, and a rotatable structure 3. In addition, the first conductive member 1 is electrically connected to the first electrode P1, the second conductive member 2 is electrically connected to the second electrode P2, and the rotatable structure 3 is rotatably disposed on the second conductive member 2 and rotatably contacts the first conductive member 1. It should be noted that, as shown in fig. 2, a contact point (not numbered) is provided between the rotatable structure 3 and the first conductive member 1, and the present application can change the resistance value provided by the variable resistance component S by adjusting the adjustable distance H between the contact point and the end of the first conductive member 1. In addition, the variable resistance component S may be a resistance adjuster.

Further, the first conductive member 1 and the second conductive member 2 can be made of any conductive material. For example, the first conductive member 1 may be a carbon film or any other conductive member, and the second conductive member 2 may be a carbon brush or any other conductive member, but the present application is not limited thereto. In addition, the first electrode P1 and the second electrode P2 can be a positive electrode and a negative electrode, respectively, or the first electrode P1 and the second electrode P2 can be a negative electrode and a positive electrode, respectively.

Further, the first conductive member 1 and the second conductive member 2 are separated from each other, and the second conductive member 2 is movably disposed above the first conductive member 1. For example, the second conductive member 2 can move linearly above the first conductive member 1, or the second conductive member 2 can move in an arc above the first conductive member 1. In addition, the second conductive member 2 may be an elastic conductive member for providing a predetermined elastic force, so the rotatable structure 3 can be pushed down against the first conductive member 1 by the elastic force provided by the second conductive member 2.

Still further, the rotatable structure 3 has an arc surface capable of slidably contacting the first conductive member 1, thereby reducing the friction resistance (or friction coefficient) between the rotatable structure 3 and the first conductive member 1. That is, when the second conductive member 2 brings the rotatable structure 3 into contact with the first conductive member 1, since the rotatable structure 3 is in sliding contact with the first conductive member 1 by the arc surface thereof, the friction resistance (or friction coefficient) between the rotatable structure 3 and the first conductive member 1 is reduced, and the wear rate of both the rotatable structure 3 and the first conductive member 1 is reduced. Therefore, the service life and the product reliability of the variable resistance assembly S can be improved by using the rotatable structure 3.

For example, the second conductive member 2 has two extension arms 21 corresponding to each other and an accommodating space 22 formed between the two extension arms 21. Furthermore, the rotatable structure 3 comprises a pivot shaft 30 and a pivot roller 31. The pivot shaft 30 is connected between the two extending arms 21 and is accommodated in the accommodating space 22, and the pivot roller 31 can be pivotally disposed on the pivot shaft 30 and partially exposed out of the accommodating space 22. In addition, the pivot roller 31 has a circular arc surface 310 slidably contacting the first conductive member 1.

Therefore, since the pivot roller 31 has the arc surface 310 capable of slidably contacting the first conductive member 1, the friction resistance (or friction coefficient) between the pivot roller 31 and the first conductive member 1 is reduced, and the wear rate of both the pivot roller 31 and the first conductive member 1 is reduced. Therefore, the service life and the product reliability of the variable resistor assembly S can be improved by using the pivot roller 31.

In addition, the second conductive member 2 of the present application may further include at least one blocking portion 24 extending toward the first conductive member 1, and a gap d is formed between the at least one blocking portion 24 and the first conductive member 1 to block the passage of foreign materials. For example, as shown in fig. 1 and fig. 2, the second conductive member 2 further has at least one blocking portion 24, wherein two blocking portions 24 corresponding to each other are taken as an example in the present embodiment, but not limited thereto. For example, as shown in fig. 1 and fig. 2, a surface of the second conductive member 2 corresponding to the first conductive member 1 has two blocking portions 24. The direction of the stop portion 24 is perpendicular to the direction of displacement of the rotatable structure 3, but not limited thereto. Therefore, the variable resistance module S of the present application can block the external foreign object from entering the accommodating space 22 in the process of the displacement of the rotatable structure 3 through the arrangement of the blocking portion 24, so as to prevent the external foreign object from being stained and adhered to the pivot roller 31, and thus the accuracy of sensing the first conductive member 1 by the rotatable structure 3 is affected and reduced. Wherein, the foreign matter can be sand dust, fly ash, dust or other substances, the size of the sand dust is between 90 and 2000 microns, the size of the fly ash is between 3 and 80 microns, and the size of the dust is between 0.9 and 120 microns; therefore, the size of the gap d of the present application may be changed according to the object size of the foreign matter to be blocked. In other words, the size of the gap d may be between 0.9 and 2000 and include any positive integer (in microns) from 1 to 2000.

However, the above-mentioned example is only one possible embodiment and is not intended to limit the present application.

Second embodiment

Referring to fig. 3, a second embodiment of the present application provides a variable resistance device S, including: a first conductive member 1, a second conductive member 2, and a rotatable structure 3. As can be seen from a comparison between fig. 3 and fig. 1, the greatest difference between the second embodiment and the first embodiment of the present application is: the first embodiment uses a "pivoting roller 31 having a circular arc surface 310" (as shown in fig. 1), while the second embodiment uses a "pivoting ball 32 having a spherical surface 320" (as shown in fig. 3). Therefore, depending on the requirements, the rotatable structure 3 can be "using a pivoting roller 31 with a circular arc surface 310" (as shown in fig. 1) or "using a pivoting ball 32 with a spherical surface 320" (as shown in fig. 3).

Further, as shown in FIG. 3, the rotatable structure 3 includes a pivot shaft 30 and a pivot ball 32. The pivot shaft 30 is connected between the two extending arms 21 and is accommodated in the accommodating space 22, and the pivot ball 32 can be pivotally disposed on the pivot shaft 30 and partially exposed out of the accommodating space 22. In addition, the pivot ball 32 has a spherical surface 320 which can slidably contact the first conductive member 1.

Therefore, since the pivot ball 32 has the spherical surface 320 capable of slidably contacting the first conductive device 1, the frictional resistance between the pivot ball 32 and the first conductive device 1 is reduced, and the wear rate of the pivot ball 32 and the first conductive device 1 is also reduced. Therefore, the service life and the product reliability of the variable resistance element S can be improved by using the pivot ball 32.

In addition, as shown in fig. 3, the second conductive member 2 in this embodiment may also include at least one blocking portion 24 extending toward the first conductive member 1, and two blocking portions 24 corresponding to each other are taken as an example in this embodiment, but not limited thereto. Therefore, by the arrangement of the blocking portion 24, in the process of displacement of the pivot ball 32, external foreign objects are blocked from entering the accommodating space 22, so as to prevent the external foreign objects from being stained and adhered to the pivot ball 32, thereby affecting and reducing the accuracy of the rotatable structure 3 sensing the first conductive component 1.

However, the above-mentioned example is only one possible embodiment and is not intended to limit the present application.

Third embodiment

Referring to fig. 4 and 5, a variable resistance device S according to a third embodiment of the present application includes: a first conductive member 1, a second conductive member 2, and a rotatable structure 3. As can be seen from a comparison between fig. 4 and fig. 1, and a comparison between fig. 5 and fig. 2, the greatest difference between the third embodiment and the first embodiment of the present application is: the second conductive member 2 of the third embodiment has a single extension arm 21.

More specifically, the rotatable structure 3 includes a pivot shaft 30 and two pivot rollers 31. The pivot shaft 30 extends through the extension arm 21, and two pivot rollers 31 are pivotally disposed on opposite ends of the pivot shaft 30 and separated by the extension arm 21. In addition, the pivot roller 31 has a circular arc surface 310 slidably contacting the first conductive member 1.

Therefore, since the pivot roller 31 has the arc surface 310 capable of slidably contacting the first conductive member 1, the frictional resistance between the pivot roller 31 and the first conductive member 1 is reduced, and the wear rate of both the pivot roller 31 and the first conductive member 1 is reduced. Therefore, the service life and the product reliability of the variable resistor assembly S can be improved by using the pivot roller 31.

In addition, as shown in fig. 4 and fig. 5, the second conductive member 2 in this embodiment may also include at least one blocking portion 24 extending toward the first conductive member 1, and in this embodiment, two blocking portions 24 corresponding to each other are taken as an example, but not limited thereto. Therefore, by the arrangement of the blocking portion 24, in the process of displacement of the pivot roller 31, the external foreign object is blocked from entering the accommodating space 22, so as to prevent the external foreign object from being stained and adhered to the arc surface 310 of the pivot roller 31, thereby affecting and reducing the accuracy of sensing the first conductive member 1 by the rotatable structure 3.

However, the above-mentioned example is only one possible embodiment and is not intended to limit the present application.

Fourth embodiment

Referring to fig. 6, a fourth embodiment of the present application provides a variable resistance device S, including: a first conductive member 1, a second conductive member 2, and a rotatable structure 3. As can be seen from a comparison between fig. 6 and fig. 4, the biggest difference between the fourth embodiment and the third embodiment of the present application is: the third embodiment uses a "pivoting roller 31 having a circular arc surface 310" (as shown in fig. 4), while the fourth embodiment uses a "pivoting ball 32 having a spherical surface 320" (as shown in fig. 6). Therefore, the rotatable structure 3 can be "using the pivoting roller 31 with the circular arc surface 310" (as shown in fig. 4) or "using the pivoting ball 32 with the spherical surface 320" (as shown in fig. 6) according to different requirements.

Further, as shown in fig. 6, the rotatable structure 3 includes a pivot shaft 30 and two pivot balls 32. The pivot shaft 30 can penetrate the extension arm 21, and the two pivot balls 32 can be pivotally disposed on opposite side ends of the pivot shaft 30 and separated by the extension arm 21. In addition, the pivot ball 32 has a spherical surface 320 which can slidably contact the first conductive member 1.

Therefore, since the pivot ball 32 has the spherical surface 320 capable of slidably contacting the first conductive device 1, the frictional resistance between the pivot ball 32 and the first conductive device 1 is reduced, and the wear rate of the pivot ball 32 and the first conductive device 1 is also reduced. Therefore, the service life and the product reliability of the variable resistance element S can be improved by using the pivot ball 32.

In addition, as shown in fig. 6, the second conductive member 2 in this embodiment may also include at least one blocking portion 24 extending toward the first conductive member 1, and two blocking portions 24 corresponding to each other are taken as an example in this embodiment, but not limited thereto. Therefore, by the arrangement of the blocking portion 24, in the process of displacement of the pivot ball 32, external foreign objects are blocked from entering the accommodating space 22, so as to prevent the external foreign objects from being stained and adhered to the spherical surface 320 of the pivot ball 32, thereby affecting and reducing the accuracy of sensing the first conductive element 1 by the rotatable structure 3.

However, the above-mentioned example is only one possible embodiment and is not intended to limit the present application.

Fifth embodiment

Referring to fig. 7 and 8, a fifth embodiment of the present invention provides a variable resistance device S, including: a first conductive member 1, a second conductive member 2, and a rotatable structure 3. As can be seen from a comparison between fig. 7 and fig. 1, and a comparison between fig. 8 and fig. 2, the biggest difference between the fifth embodiment and the first embodiment of the present application is: the bottom surface of the second conductive member 2 of the fifth embodiment has a groove 23.

More specifically, the rotatable structure 3 includes a pivot shaft 30 and a pivot roller 31. The pivot shaft 30 is accommodated in the groove 23, and the pivot roller 31 can be pivotally disposed on the pivot shaft 30 and partially exposed outside the groove 23. In addition, the pivot roller 31 has a circular arc surface 310 slidably contacting the first conductive member 1.

Therefore, since the pivot roller 31 has the arc surface 310 capable of slidably contacting the first conductive member 1, the frictional resistance between the pivot roller 31 and the first conductive member 1 is reduced, and the wear rate of both the pivot roller 31 and the first conductive member 1 is reduced. Therefore, the service life and the product reliability of the variable resistor assembly S can be improved by using the pivot roller 31.

In addition, as shown in fig. 7 and fig. 8, the second conductive member 2 in this embodiment may also include at least one blocking portion 24 extending toward the first conductive member 1, and in this embodiment, two blocking portions 24 corresponding to each other are taken as an example, but not limited thereto. Therefore, by the arrangement of the blocking portion 24, in the process of displacement of the pivot roller 31, the external foreign object is blocked from entering the accommodating space 22, so as to prevent the external foreign object from being stained and adhered to the arc surface 310 of the pivot roller 31, thereby affecting and reducing the accuracy of sensing the first conductive member 1 by the rotatable structure 3.

However, the above-mentioned example is only one possible embodiment and is not intended to limit the present application.

Sixth embodiment

Referring to fig. 9, a sixth embodiment of the present application provides a variable resistance element S, including: a first conductive member 1, a second conductive member 2, and a rotatable structure 3. As can be seen from a comparison between fig. 9 and fig. 7, the biggest difference between the sixth embodiment and the fifth embodiment of the present application is: the fifth embodiment uses a "pivoting roller 31 having a circular arc surface 310" (as shown in fig. 7), while the sixth embodiment uses a "pivoting ball 32 having a spherical surface 320" (as shown in fig. 9). Therefore, the rotatable structure 3 can be "using the pivoting roller 31 with the circular arc surface 310" (as shown in fig. 7) or "using the pivoting ball 32 with the spherical surface 320" (as shown in fig. 9) according to different requirements.

Further, as shown in fig. 9, the rotatable structure 3 includes a pivot shaft 30 and a pivot ball 32. The pivot shaft 30 is received in the recess 23, and the pivot ball 32 can be pivotally disposed on the pivot shaft 30 and partially exposed out of the recess 23. In addition, the pivot ball 32 has a spherical surface 320 capable of slidably contacting the first conductive member 1.

Therefore, since the pivot ball 32 has the spherical surface 320 capable of slidably contacting the first conductive device 1, the frictional resistance between the pivot ball 32 and the first conductive device 1 is reduced, and the wear rate of the pivot ball 32 and the first conductive device 1 is also reduced. Therefore, the service life and the product reliability of the variable resistance element S can be improved by using the pivot ball 32.

In addition, as shown in fig. 7 and fig. 8, the second conductive member 2 in this embodiment may also include at least one blocking portion 24 extending toward the first conductive member 1, and in this embodiment, two blocking portions 24 corresponding to each other are taken as an example, but not limited thereto. Therefore, by the arrangement of the blocking portion 24, in the process of displacement of the pivot ball 32, external foreign objects are blocked from entering the accommodating space 22, so as to prevent the external foreign objects from being stained and adhered to the spherical surface 320 of the pivot ball 32, thereby affecting and reducing the accuracy of sensing the first conductive element 1 by the rotatable structure 3.

However, the above-mentioned example is only one possible embodiment and is not intended to limit the present application.

Seventh embodiment

Referring to fig. 10 and 11, a seventh embodiment of the present application provides a variable resistance device S, including: a first conductive member 1, a second conductive member 2, and a rotatable structure 3. As can be seen from a comparison between fig. 10 and fig. 1, and a comparison between fig. 11 and fig. 2, the seventh embodiment of the present application has the greatest difference from the first embodiment: in the seventh embodiment, the bottom surface of the second conductive member 2 has a recess 23, and the rotatable structure 3 includes a rolling sphere 33 partially disposed in the recess 23. In addition, the rolling ball 33 is rollably disposed in the recess 23, and the rolling ball 33 has a spherical surface 330 slidably contacting the first conductive member 1.

Thereby, since the rolling ball 33 has the spherical surface 330 slidably contacting the first conductive member 1, the friction resistance between the rolling ball 33 and the first conductive member 1 is reduced, and the wear rate of both the rolling ball 33 and the first conductive member 1 is reduced. Therefore, the service life and the product reliability of the variable resistance element S can be improved by using the rolling ball 33.

It should be noted that, in the present embodiment, the second conductive member 2 may have at least one blocking portion 24, and the blocking portion 24 may be in a shape of a ring, an arc, an L, a square, or a geometric shape, and the present embodiment takes the shape of a ring as an example, but not limited thereto. Therefore, by the arrangement of the blocking portion 24, in the process of displacement of the rolling ball 33, the external foreign object can be blocked from entering the accommodating space 22, so as to prevent the external foreign object from being adhered and adhered to the spherical surface 330 of the rolling ball 33, which affects and reduces the accuracy of the rotatable structure 3 sensing the first conductive component 1.

However, the above-mentioned example is only one possible embodiment and is not intended to limit the present application.

The mechanical regulating device D uses a variable resistance element S, and the variable resistance element S may be any one of the first to seventh embodiments. For example, as shown in fig. 2, the variable resistance component S includes a first conductive member 1, a second conductive member 2, and a rotatable structure 3.

More specifically, as shown in fig. 2 and 12, the mechanical control device D further includes a control component. The control component and the variable resistance component S can be matched with each other, and the second conductive component 2 can be driven by the control component to move linearly or move in an arc relative to the first conductive component 1. For example, the control component may be a knob R. By turning the knob R (in the direction indicated by the arrow), the second conductive member 2 can drive the rotatable structure 3 to move linearly or arcuately on the first conductive member 1, thereby changing the resistance value provided by the variable resistance component S.

However, the above-mentioned example is only one possible embodiment and is not intended to limit the present application.

Ninth embodiment

Referring to fig. 13, a ninth embodiment of the present application provides a mechanical control device D. The mechanical regulating device D uses a variable resistance element S, and the variable resistance element S may be any one of the first to seventh embodiments. For example, as shown in fig. 2, the variable resistance component S includes a first conductive member 1, a second conductive member 2, and a rotatable structure 3.

More specifically, as shown in fig. 2 and 13, the mechanical control device D further includes a control component. The control component and the variable resistance component S can be matched with each other, and the second conductive component 2 can be driven by the control component to move linearly or move in an arc relative to the first conductive component 1. For example, the control component may be a toggle M. By moving the toggle member M left and right (as indicated by the arrow), the second conductive member 2 can drive the rotatable structure 3 to move linearly or arcuately on the first conductive member 1, thereby changing the resistance value provided by the variable resistance component S.

However, the above-mentioned examples are only one possible embodiment and are not intended to limit the present disclosure.

Advantageous effects of the embodiments

One of the benefits of the present application lies in that, the mechanical regulation device D and the variable resistance component S thereof provided by the present application can be rotatably disposed on the second conductive member 2 through the "rotatable structure 3 and can rotatably contact the first conductive member 1", the "rotatable structure 3 has an arc surface that can slidably contact the first conductive member 1", and the "second conductive member 2 includes the blocking portion 24 extending toward the first conductive member 1, a gap D is formed between the blocking portion 24 and the first conductive member 1 to block the passage of the foreign object", so as to reduce the frictional resistance between the rotatable structure 3 and the first conductive member 1, and avoid the foreign object from contacting the rotatable structure 3.

That is, when the second conductive member 2 brings the rotatable structure 3 into contact with the first conductive member 1, since the rotatable structure 3 is in sliding contact with the first conductive member 1 by the arc surface thereof, the friction resistance (or friction coefficient) between the rotatable structure 3 and the first conductive member 1 is reduced, and the wear rate of both the rotatable structure 3 and the first conductive member 1 is reduced. Therefore, the service life and the product reliability of the variable resistance assembly S can be improved by using the rotatable structure 3. In addition, in the process of displacement of the rotatable structure 3, the blocking portion 24 is disposed to block external foreign objects from entering the accommodating space 22, so as to prevent the external foreign objects from being adhered to the rotatable structure 3, thereby affecting and reducing the accuracy of sensing the first conductive member 1 by the rotatable structure 3.

The disclosure is only a preferred embodiment of the present application and is not intended to limit the scope of the claims of the present application, so that all technical equivalents and modifications made by the disclosure of the present application and the drawings are included in the scope of the claims of the present application.
