Detailed Description

The following is a description of the embodiments of the mechanical encoder and its mechanical moving element disclosed in the present application with specific embodiments, and those skilled in the art can understand the advantages and effects of the present application from the disclosure of the present application. The present application is capable of other and different embodiments and its several details are capable of modification and various changes in detail without departing from the spirit and scope of the present application. 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 to 4, a first embodiment of the present application provides a mechanical movable element S, including: a first mating member 1, a second mating member 2 and a rotatable structure 3. In addition, the first mating member 1 has a plurality of conductive regions 11 electrically connected to the first electrode P1 and a plurality of insulating regions 12 insulated from each other from the first electrode P1, the second mating member 2 is electrically connected to the second electrode P2, and the rotatable structure 3 is rotatably disposed on the second mating member 2 and rotatably contacts one of the conductive regions 11 and the insulating regions 12 of the first mating member 1. For example, the plurality of conductive regions 11 and the plurality of insulating regions 12 may be alternately arranged, and the mechanically movable element S may be applied to a mechanical encoder (not shown). As shown in fig. 1 and 3, when the rotatable structure 3 contacts the conductive area 11 of the first mating member 1, the mechanical encoder outputs a path signal (i.e., a high voltage signal) indicated as 1. As shown in fig. 2 and 4, when the rotatable structure contacts the insulation region 12 of the first mating member 1, the mechanical encoder outputs an open circuit signal (i.e., a low voltage signal) represented as 0. That is, when the first mating member 1 moves relative to the second mating member 2 such that the rotatable structure 3 alternately contacts the conductive region 11 and the insulating region 12 of the first mating member 1, the mechanical encoder sequentially outputs signals of 1,0, 1,0 ….

Furthermore, the first mating member 1 and the second mating member 2 can be made of any conductive material. For example, the first mating member 1 may be a strip-shaped substrate or a disc-shaped substrate having a plurality of conductive regions 11 and a plurality of insulating regions 12, and the second mating member 2 may be a conductive spring or any other conductive body, 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 fitting member 1 and the second fitting member 2 are separated from each other, and the first fitting member 1 is movably disposed below the second fitting member 2. For example, the first fitting member 1 can move linearly under the second fitting member 2, or the first fitting member 1 can move arcuately under the second fitting member 2.

Furthermore, the second mating member 2 may be an elastic conductive member for providing a predetermined elastic force, so that the rotatable structure 3 can be pushed downward against the first mating member 1 by the elastic force provided by the second mating member 2.

Further, the rotatable structure 3 has an arc-shaped surface capable of slidably contacting one of the conductive region 11 and the insulating region 12 of the first mating member 1, thereby reducing the frictional resistance (or coefficient of friction) between the rotatable structure 3 and the first mating member 1. That is, when the first mating member 1 is brought to enable the rotatable structure 3 to slidably contact the first mating member 1, since the rotatable structure 3 slidably contacts the first mating member 1 with the arc surface thereof, the frictional resistance (or friction coefficient) between the rotatable structure 3 and the first mating member 1 is reduced, and the wear rate of both the rotatable structure 3 and the first mating member 1 is reduced. Therefore, the service life and the product reliability of the mechanical movable assembly S can be improved by using the rotatable structure 3.

For example, the second fitting 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 one of the conductive region 11 and the insulating region 12 of the first mating member 1.

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

In addition, the second mating member 2 of the present application may further include at least one blocking portion 24 extending toward the first mating member 1, and a gap h 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 to 4, the second fitting part 2 further has at least one blocking portion 24, and in the present embodiment, two blocking portions 24 corresponding to each other are taken as an example, but not limited thereto. The second fitting part 2 of the present application has two stops 24 on the side corresponding to the first fitting part 1. 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 mechanical movable assembly S of the present application can block the external foreign object from entering the accommodating space 22 in the process of displacement of the pivot roller 31 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 to influence and reduce the accuracy of the rotatable structure 3 sensing the first mating member 1. 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 h 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 h 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. 5, a second embodiment of the present application provides a mechanical movable assembly S, which includes: a first mating member 1, a second mating member 2 and a rotatable structure 3. As can be seen from a comparison between fig. 5 and fig. 1, the greatest difference between the second embodiment and the first embodiment of the present application is: the first embodiment uses the "pivoting roller 31 having the circular arc surface 310 (shown in fig. 1)", and the second embodiment uses the "pivoting ball 32 having the spherical surface 320 (shown in fig. 5)". Therefore, the rotatable structure 3 can be "using the pivoting roller 31 with the circular arc surface 310 (as shown in fig. 1)" or "using the pivoting ball 32 with the spherical surface 320 (as shown in fig. 5)" according to different requirements.

Further, as shown in fig. 5, 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 that slidably contacts one of the conductive region 11 and the insulating region 12 of the first mating member 1.

Thereby, since the pivot ball 32 has the spherical surface 320 capable of slidably contacting the first mating member 1, the frictional resistance between the pivot ball 32 and the first mating member 1 is reduced, and the wear rate of the pivot ball 32 and the first mating member 1 is also reduced. Therefore, the service life and the product reliability of the mechanical movable assembly S can be improved by using the pivot ball 32.

Furthermore, the second fitting part 2 has at least one stop 24. For example, as shown in fig. 5, in the present embodiment, the second fitting 2 is exemplified by two blocking portions 24 corresponding to each other, but not limited thereto. Therefore, by the arrangement of the blocking portion 24, in the process of displacement of the pivot ball 32, the foreign object can be blocked from entering the accommodating space 22, so as to prevent the foreign object from being stained and adhered to the spherical surface 320 of the pivot ball 32, thereby affecting and reducing the accuracy of the rotatable structure 3 sensing the first mating member 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. 6 and 7, a third embodiment of the present application provides a mechanical movable assembly S, including: a first mating member 1, a second mating member 2 and a rotatable structure 3. As can be seen from a comparison between fig. 6 and fig. 1, and a comparison between fig. 7 and fig. 3, the greatest difference between the third embodiment and the first embodiment of the present application is: the second fitting 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 one of the conductive region 11 and the insulating region 12 of the first mating member 1.

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

Furthermore, the second fitting part 2 has at least one stop 24. For example, as shown in fig. 6 and fig. 7, in the present embodiment, the second fitting element 2 is exemplified by two blocking portions 24 corresponding to each other, 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 the rotatable structure 3 sensing the first mating member 1.

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

Fourth embodiment

Referring to fig. 8, a fourth embodiment of the present application provides a mechanical movable assembly S, including: a first mating member 1, a second mating member 2 and a rotatable structure 3. As can be seen from a comparison between fig. 8 and fig. 6, the biggest difference between the fourth embodiment and the third embodiment of the present application is: the third embodiment uses the "pivoting roller 31 having the circular arc surface 310 (shown in fig. 6)", and the fourth embodiment uses the "pivoting ball 32 having the spherical surface 320 (shown in fig. 8)". Therefore, the rotatable structure 3 can be "using the pivoting roller 31 with the circular arc surface 310 (as shown in fig. 6)" or "using the pivoting ball 32 with the spherical surface 320 (as shown in fig. 8)" according to different requirements.

Further, as shown in fig. 8, 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 that slidably contacts one of the conductive region 11 and the insulating region 12 of the first mating member 1.

Thereby, since the pivot ball 32 has the spherical surface 320 capable of slidably contacting the first mating member 1, the frictional resistance between the pivot ball 32 and the first mating member 1 is reduced, and the wear rate of the pivot ball 32 and the first mating member 1 is also reduced. Therefore, the service life and the product reliability of the mechanical movable assembly S can be improved by using the pivot ball 32.

Furthermore, the second fitting part 2 has at least one stop 24. For example, as shown in fig. 8, in the present embodiment, the second fitting 2 is exemplified by two blocking portions 24 corresponding to each other, but not limited thereto. Therefore, by the arrangement of the blocking portion 24, in the process of displacement of the pivot ball 32, the foreign object can be blocked from entering the accommodating space 22, so as to prevent the foreign object from being stained and adhered to the spherical surface 320 of the pivot ball 32, thereby affecting and reducing the accuracy of the rotatable structure 3 sensing the first mating member 1.

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

Fifth embodiment

Referring to fig. 9 and 10, a fifth embodiment of the present application provides a mechanical movable element S, including: a first mating member 1, a second mating member 2 and a rotatable structure 3. As can be seen from a comparison between fig. 9 and fig. 1, and a comparison between fig. 10 and fig. 3, the biggest difference between the fifth embodiment and the first embodiment of the present application is: the bottom surface of the second fitting 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 one of the conductive region 11 and the insulating region 12 of the first mating member 1.

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

Furthermore, the second fitting part 2 has at least one stop 24. For example, as shown in fig. 8, in the present embodiment, the second fitting 2 is exemplified by two blocking portions 24 corresponding to each other, 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 the rotatable structure 3 sensing the first mating member 1.

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

Sixth embodiment

Referring to fig. 11, a sixth embodiment of the present application provides a mechanical movable assembly S, including: a first mating member 1, a second mating member 2 and a rotatable structure 3. As can be seen from a comparison between fig. 11 and fig. 9, the biggest difference between the sixth embodiment and the fifth embodiment of the present application is: the fifth embodiment uses the "pivot roller 31 having the circular arc surface 310 (shown in fig. 9)", and the sixth embodiment uses the "pivot ball 32 having the spherical surface 320 (shown in fig. 11)". Therefore, the rotatable structure 3 can be "using the pivoting roller 31 with the circular arc surface 310 (as shown in fig. 9)" or "using the pivoting ball 32 with the spherical surface 320 (as shown in fig. 11)" according to different requirements.

Further, as shown in fig. 11, 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 that slidably contacts one of the conductive region 11 and the insulating region 12 of the first mating member 1.

Thereby, since the pivot ball 32 has the spherical surface 320 capable of slidably contacting the first mating member 1, the frictional resistance between the pivot ball 32 and the first mating member 1 is reduced, and the wear rate of the pivot ball 32 and the first mating member 1 is also reduced. Therefore, the service life and the product reliability of the mechanical movable assembly S can be improved by using the pivot ball 32.

Furthermore, the second fitting part 2 has at least one stop 24. For example, as shown in fig. 8, in the present embodiment, the second fitting 2 is exemplified by two blocking portions 24 corresponding to each other, 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 adhered to the spherical surface 320 of the pivot ball 32, thereby affecting and reducing the accuracy of the rotatable structure 3 sensing the first mating member 1.

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

Seventh embodiment

Referring to fig. 12 and 13, a seventh embodiment of the present application provides a mechanical movable assembly S, including: a first mating member 1, a second mating member 2 and a rotatable structure 3. As can be seen from a comparison between fig. 12 and fig. 1, and a comparison between fig. 13 and fig. 3, the seventh embodiment of the present application has the following greatest difference from the first embodiment: in the seventh embodiment, the bottom surface of the second fitting element 2 has a recess 23, and the rotatable structure 3 comprises a rolling ball 33 partly arranged in the recess 23. In addition, the rolling ball 33 is rollably disposed in the groove 23, and the rolling ball 33 has a spherical surface 330 slidably contacting one of the conductive area 11 and the insulating area 12 of the first mating member 1.

Thereby, since the rolling ball 33 has the spherical surface 330 slidably contacting the first mating member 1, the frictional resistance between the rolling ball 33 and the first mating member 1 is reduced, and the wear rate of both the rolling ball 33 and the first mating member 1 is also reduced. Therefore, the service life and the product reliability of the mechanical movable assembly S can be improved by using the rolling ball 33.

It should be noted that in the present embodiment, the second mating member 2 may have at least one blocking portion 24, and the blocking portion 24 may be in a ring shape, an arc shape, an L shape, a square shape or a geometric shape, and the present embodiment takes the ring shape 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 to the spherical surface 330 of the rolling ball 33, which affects and reduces the accuracy of the rotatable structure 3 sensing the first mating member 1.

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

Eighth embodiment

Referring to fig. 14, an eighth embodiment of the present application provides a mechanical encoder D. The mechanical encoder D uses a mechanically movable member S, and the mechanically movable member S may be any one of the first to seventh embodiments. For example, as shown in fig. 3 and 4, the mechanical movable assembly S includes a first fitting member 1, a second fitting member 2, and a rotatable structure 3.

More specifically, as shown in fig. 3, 4 and 14, the mechanical encoder D further includes a control component. The control component and the mechanical movable component S can be matched with each other, and the first conductive component 1 can be driven by the control component to move linearly or move in an arc relative to the second conductive component 2. For example, the mechanical encoder D can be applied to a mouse, the mechanical movable assembly S uses two rotatable structures 3, and the control assembly can be a rotatable member R.

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

Ninth embodiment

Referring to fig. 15, a ninth embodiment of the present application provides a mechanical encoder D. The mechanical encoder D uses a mechanically movable member S, and the mechanically movable member S may be any one of the first to seventh embodiments. For example, as shown in fig. 3 and 4, the mechanical movable assembly S includes a first fitting member 1, a second fitting member 2, and a rotatable structure 3.

More specifically, as shown in fig. 3, 4 and 15, the mechanical encoder D further includes a control component. The control component and the mechanical movable component S can be matched with each other, and the first conductive component 1 can be driven by the control component to move linearly or move in an arc relative to the second conductive component 2.

For example, the mechanical encoder D can be applied to a mouse, the mechanical moving component S uses two first engaging members 1 and two rotatable structures 3, and the control component can be a moving member M. As shown in fig. 15 and 16, when both rotatable structures 3 contact the insulation region 12 of the first mating member 1, the mechanical encoder D outputs an encoded signal of (0, 0). The mechanical encoder D outputs an encoded signal of (0,1) when the two rotatable structures 3 contact the insulating region 12 and the conductive region 11 of the first mating member 1, respectively. When both rotatable structures 3 contact the conductive area 11 of the first mating member 1, the mechanical encoder D outputs an encoded signal of (1, 1). The mechanical encoder D outputs an encoded signal of (1,0) when the two rotatable structures 3 contact the conductive area 11 and the insulating area 12 of the first mating member 1, respectively. Therefore, the first mating member 1 can be driven by the moving member M (in the direction shown by the arrow) to move linearly relative to the second mating member 2, so that the mechanically movable assembly S can generate the coded signals of (0,0), (0,1), (1,1) and (1,0) in sequence.

In addition, as shown in fig. 17, the two first fitting members 1 may be stacked on each other and connected to each other. Also, the two rotatable structures 3 may be disposed opposite to each other and each contacting the corresponding rotatable structure 3. The two rotatable structures 3 contact the corresponding insulating region 12 and conductive region 11 of the first mating member 1, respectively, so that the mechanical encoder D outputs a corresponding encoded signal.

It should be noted that, when the mechanical movable assembly S uses three first engaging members 1 and three rotatable structures 3, the mechanical movable assembly S can sequentially generate 9 encoded signals. Therefore, the number of the second engaging members 2 and the rotatable structure 3 is not limited to the above-mentioned examples.

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

Advantageous effects of the embodiments

One of the advantages of the present application is that the mechanical encoder D and the mechanical movable assembly S thereof provided by the present application can reduce the friction resistance between the rotatable structure 3 and the first mating member 1 by the technical solutions of "the rotatable structure 3 is rotatably disposed on the second mating member 2 and can rotatably contact one of the conductive area 11 and the insulating area 12 of the first mating member 1" and "the rotatable structure 3 has the arc surface that can slidably contact the first mating member 1".

That is, when the second mating member 2 is brought to enable the rotatable structure 3 to slidably contact the first mating member 1, since the rotatable structure 3 slidably contacts the first mating member 1 with the arc surface thereof, the frictional resistance (or friction coefficient) between the rotatable structure 3 and the first mating member 1 is reduced, and the wear rate of both the rotatable structure 3 and the first mating member 1 is reduced. Therefore, the service life and the product reliability of the mechanical movable assembly S can be improved by using the rotatable structure 3.
