[0035] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features therein can be combined with each other in the absence of conflict.

[0036] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0037] Figure 1 FIG. 1 is a top view of a rotary button provided by an embodiment of the present disclosure. Figure 2 FIG. 1 is a bottom view of a rotary button provided by an embodiment of the present disclosure. Figure 3 Shown Figure 1 The structural diagram of some components in the rotary button, Figure 4 Shown Figure 1 For the cross-sectional view of the rotating button along A-A', please refer to Figures 1 to 4 The present disclosure provides a rotary button 100, comprising a fixed component 70 and a rotating component 80, wherein the rotating component 80 can rotate relative to the fixed component 70. Figure 3 The fixing assembly 70 includes a bracket 30 and a base 60. The bracket 30 is fixed to one side of the base 60. It can be understood that the rotating assembly 80 and the bracket 30 are located on the same side of the base 60. It should be noted that Figure 3 The example of the rotary button 100 including both the first internal conductive pillar 01 and the second internal conductive pillar 02 is used for illustration. It is understandable that the rotary button 100 may also include only the first internal conductive pillar 01 , and the present disclosure is not limited to this.

[0038] The rotating assembly 80 includes a conductive ring 10, a top cover 20 and a rotating wheel 40. It can be understood that the rotating assembly 80 can rotate relative to the fixed assembly 70, that is, the conductive ring 10, the top cover 20 and the rotating wheel 40 can all rotate relative to the fixed assembly 70. The top cover 20 is made of insulating material, please refer to Figure 3 and Figure 4The top cover 20 comprises an outer top cover 21 and an inner top cover 22, the inner top cover 22 is located inside the outer top cover 21, the outer top cover 21 is annular, and the inner top cover 22 is annular and has a containing space, the diameter of the outer top cover 21 is slightly larger than that of the inner top cover 22 so as to arrange the inner top cover 22 inside the outer top cover 21, of course, the inner top cover 22 and the outer top cover 21 can also have other shapes and structures, and the present disclosure does not limit this. In the direction parallel to the plane where the base 60 is located, the conductive ring 10 is located between the inner top cover 22 and the outer top cover 21; the conductive ring 10 is nested with the inner top cover 22, and the top cover 20 rotates to drive the conductive ring 10 to rotate.

[0039] Please refer to Figure 4 In the direction perpendicular to the plane where the base 60 is located, the rotating wheel 40 is located between the support 30 and the base 60, and the rotating wheel 40 is located inside the inner top cover 22, for example, the rotating wheel 40 can be located in the containing space inside the inner top cover 22, and the top cover 20 rotates to drive the rotating wheel 40 to rotate relative to the base 60. The side of the rotating wheel 40 facing the base 60 comprises a metal sheet 41, please refer to Figure 4 The side of the base 60 facing the rotating wheel 40 comprises an elastic sheet 54, when the rotating wheel 40 rotates relative to the base 60, the metal sheet 41 at the bottom of the rotating wheel 40 rotates, and in the process of rotation, the relative position relationship between the metal sheet 41 and the elastic sheet 54 on the base 60 changes, in addition, the metal sheet 41 contacts different elastic sheets 54 when rotating to generate different signals, which can be used to judge the rotating direction or rotating angle of the rotating button 100. The side of the base 60 away from the rotating wheel 40 comprises a metal pad 50, the elastic sheet 54 on the side of the base 60 facing the rotating wheel 40 contacts the metal sheet 41 to cause the signal amount of the metal pad 50 to change, and this signal amount change is further conducted to the electronic device 300 electrically connected with the rotating button 100 through the metal pad 50, so as to realize the manipulation of the electronic device 300 by the rotating action of the rotating button 100. The rotating button 100 further comprises an internal conductive column 00, which is used to connect the conductive ring 10 and the rotating wheel 40.

[0040] Specifically, the internal conductive column 00 is made of conductive material, including metal or metal alloy, etc., which is not limited in the present disclosure. The rotating button 100 usually needs to convert the user's operation (such as rotation angle, pressing action) into an electrical signal, and then transmit it to the electronic device electrically connected thereto. The internal conductive column 00 is made of metal material, and has a small dielectric constant, which is conducive to the conduction of electrical signals. The internal conductive column 00 can ensure that the electrical signal can be stably and continuously transmitted from the rotating part of the rotating button 100 to the electronic device during rotation. The internal conductive column 00 provided in the internal part of the rotating button 100 can provide a larger and more stable contact area, reduce the problem of poor contact, signal interruption or increased resistance caused by rotation, and ensure the reliability of signal transmission. In addition, by designing the internal conductive column 00 in the internal part of the rotating button 100, the signal conduction efficiency can be improved without increasing the size of the rotating button 100, and the limited internal space of the rotating button 100 can be effectively utilized to realize compact and reliable electrical connection, which is beneficial to improve the integration of the product. In this way, by providing the internal conductive column 00 in the internal part of the rotating button 100, the size of the rotating button 100 can be increased without increasing the size of the rotating button 100, and the internal space of the rotating button 100 can be effectively utilized to provide a reliable and stable conduction path for the rotating signal, reduce signal interruption or delay, and improve the touch sensing efficiency of the rotating button 100.

[0041] Please continue to refer to Figure 3 and Figure 4 The present disclosure provides a rotating button 100, the bracket 30 is clamped with the inner top cover 22, the bracket 30 includes a plastic bracket 31 and a metal bracket 32, the metal bracket 32 is located on the side of the plastic bracket 31 towards the rotating wheel 40; the rotating wheel 40 can rotate relative to the metal bracket 32.

[0042] Specifically, in an optional embodiment provided by the present disclosure, the fixing assembly 70 includes a base 60 and a bracket 30, the rotating assembly 80 includes a top cover 20, a conductive ring 10 and a rotating wheel 40, the bracket 30 is clamped in the accommodating space in the inner top cover 22, the bracket 30 is fixed and cannot move, and the rotating assembly 80 can rotate relative to the bracket 30 and the base 60. The bracket 30 includes a plastic bracket 31 and a metal bracket 32, and the metal bracket 32 is clamped on the side of the plastic bracket 31 towards the base 60. It can be understood that, in the direction perpendicular to the plane where the base 60 is located, the metal bracket 32 is located between the plastic bracket 31 and the rotating wheel 40. The metal bracket 32 as an intermediate layer can prevent the rotating wheel 40 from directly contacting the plastic bracket 31, reduce wear caused by friction or collision, and prolong the service life of the rotating wheel 40. The metal bracket 32 and the plastic bracket 31 can form a good damping system, the rigidity of the metal provides support, and the flexibility of the plastic absorbs part of the vibration energy, reducing the impact on the rotating wheel 40 and the base 60.

[0043] Further, the rotating wheel 40 can rotate relative to the support 30, the metal support 32 comprises at least two protrusions, the rotating wheel 40 is provided with a wave structure on one side facing the metal support 32, when the rotating wheel 40 rotates, the wave structure contacts and moves relative to the protrusions of the metal support 32, which can produce a "click, click" rotating feeling, so as to improve the user operation experience. In this way, by fixing the support 30 inside the inner top cover 22 close to one side of the rotating wheel 40, and arranging the metal support 32 between the plastic support 31 and the rotating wheel 40, the rotating feeling generated by the rotation of the rotating wheel 40 relative to the metal support 32 can improve the user experience, which is beneficial to distinguish the rotating state and the stationary state of the rotating button 100.

[0044] Optionally, the material of the metal support 32 can be metal or metal alloy, and the present disclosure does not make specific limitation thereon, and the actual process requirement is specific.

[0045] Figure 5 The other cross-sectional view of the rotating button along A-A' is shown in Figure 1 The other cross-sectional view of the rotating button along A-A' is shown in Figure 6 The structure schematic view of a first internal conductive column provided by the embodiment of the present disclosure is shown in Figure 3 、 Figure 5 and Figure 6In an optional embodiment provided by the present disclosure, when the outer top cover 21 is a metal material, the metal material includes a metal element or a metal alloy, and the present disclosure does not limit the type of metal material; the rotating button 100 can only include the first internal conductive column 01, the first internal conductive column 01 is directly connected with the conductive ring 10, and the first internal conductive column 01 is further connected with the metal sheet 41 located on the back of the rotating wheel 40 by penetrating through the plastic support 31 and the rotating wheel 40. In another optional embodiment provided by the present disclosure, when the outer top cover 21 is an insulating material, the insulating material includes an organic insulating material or an inorganic insulating material, and the present disclosure does not limit the type of insulating material; the rotating button 100 can only include the first internal conductive column 01, the first internal conductive column 01 is directly connected with the conductive ring 10, and the first internal conductive column 01 is further connected with the metal sheet 41 located on the back of the rotating wheel 40 by penetrating through the plastic support 31 and the rotating wheel 40. In still another optional embodiment provided by the present disclosure, when the outer top cover 21 is an insulating material, the rotating button 100 can simultaneously include the first internal conductive column 01 and the second internal conductive column 02, the first internal conductive column 01 is directly connected with the conductive ring 10, the first internal conductive column 01 is further connected with the metal sheet 41 located on the back of the rotating wheel 40 by penetrating through the plastic support 31 and the rotating wheel 40, the second internal conductive column 02 is located between the inner top cover and the outer top cover 21, and extends to the bottom of the conductive ring 10 along a first direction D1 to be electrically connected with the conductive ring 10, the first direction D1 is a direction perpendicular to the plane on which the base is located. That is, when the outer top cover 21 is an insulating material, when a human body touches the rotating button 100, a human body-outer top cover 21-second internal conductive column 02 forms a capacitor, and then conducts to the metal sheet 41 through the first internal conductive column 01, and then to the metal pad 50 on the side of the display panel.

[0046] For reference Figures 3 to 6 The present disclosure provides a rotating button 100, and the internal conductive column 00 includes the first internal conductive column 01, the first internal conductive column 01 is an integrated structure, and the first internal conductive column 01 is connected with the metal sheet 41 on the rotating wheel 40 by penetrating through the inner top cover 22 and the plastic support 31 along the conductive ring 10.

[0047] Specifically, in an optional embodiment provided by the present disclosure, the first internal conductive column 01 for connecting the conductive ring 10 and the rotating wheel 40 is an integrated structure, which can be a cylindrical structure, of course, other types of structures are also possible, and the present disclosure does not limit this, Figure 6The first internal conductive column 01 is only schematically shown in a cylindrical structure. It can be understood that the first internal conductive column 01 extends from the conductive ring 10 to the direction of the rotating wheel 40, wherein the first internal conductive column 01 needs to extend to the rotating wheel 40 through the inner top cover 22 and the plastic support 31, and be fixedly connected with the metal sheet 41 on the rotating wheel 40. When the user rotates the top cover 20, the rotation of the top cover 20 drives the rotation of the conductive ring 10, the first internal conductive column 01 and the rotating wheel 40. The rotation of the rotating assembly 80 causes the metal sheet 41 on the back of the rotating wheel 40 to move relative to the elastic sheet 54 on the front of the base 60, further causing the signal quantity on the metal pad 50 to change. The signal quantity change on the metal pad 50 is transmitted to the electronic device electrically connected with the rotating button 100, so as to control the volume, wind speed, light or other types of adjustment in the electronic device through the signal quantity change on the metal pad 50 on the rotating button 100. In this way, by setting the first internal conductive column 01 as an integrated structure, the internal conductive function of the rotating button 100 can be improved by the integrated first internal conductive column 01, which makes up for the signal conduction failure caused by the insufficient contact area between the user's finger and the rotating button 100, thereby improving the sensing sensitivity of the rotating button 100 and further improving the response sensitivity of the electronic device 300 to the rotating button 100.

[0048] It can be understood that, when the first internal conductive column 01 is an integrated structure, in order to realize the relative rotation of the first internal conductive column 01 and the plastic support 31, the plastic support 31 needs to be provided with a ring-shaped slot, that is, the first internal conductive column 01 divides the plastic support 31 into two relatively independent sub-supports.

[0049] Please continue to refer to Figures 4 to 6 The present disclosure provides a rotating button 100, the rotating wheel 40 includes an inner wheel 42 and an outer wheel 43, the inner wheel 42 is clamped with the inner top cover 22, the outer wheel 43 is fixed with the base 60, the outer wheel 43 is fixed and does not rotate when the rotating button 100 rotates, only the inner wheel 42 rotates; the internal conductive column 00 includes a first internal conductive column 01, the first internal conductive column 01 is located between the inner wheel 42 and the outer wheel 43; the first internal conductive column 01 is fixedly connected with the metal sheet 41.

[0050] Specifically, in an optional embodiment provided by the present disclosure, when the first internal conductive column 01 is an integrated structure, not only the plastic support 31 needs to be provided with a ring-shaped slot, but also the rotating wheel 40 needs to be provided with a ring-shaped slot to realize the connection between the first internal conductive column 01 and the metal sheet 41 at the bottom of the rotating wheel 40. The rotating wheel 40 after being provided with the ring-shaped slot includes an inner wheel 42 and an outer wheel 43, wherein the inner wheel 42 is located at a side of the first internal conductive column 01 facing the center of the inner top cover 22, and the outer wheel 43 is located at a side of the first internal conductive column 01 facing the outer top cover 21; the inner wheel 42 is clamped with the inner top cover 22, and the inner top cover 22 can drive the inner wheel 42 to rotate; the outer wheel 43 is fixed with the base 60, that is, at least part of the first internal conductive column 01 is located between the inner wheel 42 and the outer wheel 43 in a direction parallel to the plane where the base 60 is located, and the first internal conductive column 01 is connected with the metal sheet 41 at the back of the rotating wheel 40 through the gap between the inner wheel 42 and the outer wheel 43. Alternatively, the inner wheel 42 is fixedly connected with the first internal conductive column 01 and the metal sheet 41, at this time, the outer wheel 43 can be regarded as an independent part; alternatively, the first internal conductive column 01 is connected with the metal sheet 41 only, and is not connected with the inner wheel 42 and the outer wheel 43, which are not limited by the present disclosure.

[0051] Of course, in other embodiments, if the outer wheel 43 does not have other functions, this part of structure can also be removed, and the actual process needs are used for reference, in this case, it can be understood that the first internal conductive column 01 is fixedly connected with a side of the inner wheel 42 facing the outer top cover 21. When the top cover 20 rotates, the conductive ring 10, the first internal conductive column 01, the inner ring 42 and the metal sheet 41 can be regarded as a whole to rotate, and the integrated structure of the first internal conductive column 01 can improve the internal conductive function of the rotating button 100, make up for the signal conduction failure caused by the insufficient contact area between the user's finger and the rotating button 100, and thus improve the sensing sensitivity of the rotating button 100.

[0052] Figure 7 It is shown that another structure of the first internal conductive column provided by the embodiment of the present disclosure, please refer to Figure 4 、 Figure 5 and Figure 7 , the present disclosure provides a rotating button 100, the internal conductive column 00 includes a first internal conductive column 01, the first internal conductive column 01 includes a plurality of conductive strips 011, the conductive strips 011 are electrically connected with the metal sheet 41 on the rotating wheel 40 through the inner top cover 22 and the plastic support 31; the projection position of the conductive strip 011 and the metal sheet 41 on the base 60 corresponds.

[0053] Specifically, in an optional embodiment provided by the present disclosure, the first internal conductive column 01 can also be in a strip structure, and the first internal conductive column 01 includes a plurality of conductive strips 011 arranged in a ring shape. It can be understood that the conductive strips 011 correspond one-to-one to the projections of the metal sheets 41 on the back of the rotating wheel 40 on the base 60, that is, the number of the conductive strips 011 is equal to that of the metal sheets 41 and the positions correspond. The conductive strips 011 extend along the conductive ring 10 to the side of the rotating wheel 40, pass through the inner top cover 22, the plastic support 31 and the rotating wheel 40 to realize electrical connection with the metal sheets 41 on the back of the rotating wheel 40. In this case, since the first internal conductive column 01 in a strip structure rotates together with other parts such as the top cover 20, the plastic support 31 is in a fixed state, and therefore the plastic support 31 also needs to be provided with an annular groove. The rotating wheel 40 can rotate together with the first internal conductive column 01. In the case of the first internal conductive column 01 in a strip structure, the rotating wheel 40 does not need to be provided with an annular groove, and the first internal conductive column 01 can be directly fixed on the rotating wheel 40 and electrically connected with the metal sheets 41 on the back of the rotating wheel 40. At this time, the rotation of the top cover 20 can drive the conductive ring 10, the first internal conductive column 01 and the rotating wheel 40 to rotate together. Since the first internal conductive column 01 is in a strip structure, the amount of raw materials can be reduced compared with an integrated structure, and therefore the internal sensing sensitivity of the rotary button 100 can be improved and the manufacturing cost can be reduced. In this way, by setting the first internal conductive column 01 in a strip structure, the amount of raw materials can be reduced and the cost can be reduced on the basis of meeting the transmission of the rotary signal and improving the sensing efficiency of the rotary button 100.

[0054] Please continue to refer to Figure 4 The present disclosure provides a rotary button 100. When the outer top cover 21 is made of an insulating material, the internal conductive column 00 can also include a first internal conductive column 01 and a second internal conductive column 02. The second internal conductive column 02 is located between the inner top cover 22 and the outer top cover 21 and extends to the bottom of the conductive ring 10 along a first direction D1 to electrically connect with the conductive ring 10. The first direction D1 is a direction perpendicular to the plane on which the base 60 is located.

[0055] Specifically, in an optional embodiment provided by the present disclosure, the rotary button 100 comprises a first internal conductive column 01 and a second internal conductive column 02. The first internal conductive column 01 is electrically connected to the metal sheet 41 on the rotary wheel 40 through the inner top cover 22, the plastic support 31 and the conductive ring 10 in the direction of the outer top cover 21 pointing to the inner top cover 22. The second internal conductive column 02 is located between the inner top cover 22 and the outer top cover 21 in the direction perpendicular to the plane where the base 60 is located. It can be understood that the second internal conductive column 02 is in a ring structure, the inner diameter of the second internal conductive column 02 is slightly larger than the outer diameter of the inner top cover 22, and the outer diameter of the second internal conductive column 02 is slightly smaller than the inner diameter of the outer top cover 21. The second internal conductive column 02 extends along the bottom of the top cover 20 in the direction perpendicular to the plane where the base 60 is located to the position of the conductive ring 10, and extends to the bottom of the conductive ring 10 and is electrically connected thereto. In this way, by arranging the second internal conductive column 02 between the inner top cover 22 and the outer top cover 21, when the user touches the insulating outer top cover 21, the capacitance value of the capacitor composed of the human body-outer top cover 21-second internal conductive column 02 changes, and is further transmitted to the display screen electrically connected to the rotary button 100, so as to facilitate determining the coordinates of the touch position according to the change of the capacitance value.

[0056] Optionally, the outer top cover 21 and the inner top cover 22 can be made in the same process, and the injection molding process can be used to embed the prefabricated part (the second internal conductive column 02) in the process of injection molding the top cover 20, which can reduce the process and improve the bonding strength.

[0057] Please refer to Figure 4 The present disclosure provides a rotary button 100, wherein the first internal conductive column 01 and the second internal conductive column 02 at least partially overlap in the first direction D1, and the first direction D1 is the direction perpendicular to the plane where the base is located.

[0058] Specifically, in the direction perpendicular to the plane on which the base 60 lies, the first internal conductive column 01 between the conductive ring 10 and the rotating wheel 40 at least partially overlaps the second internal conductive column 02 between the outer top cover 21 and the inner top cover 22, and further, in the first direction D1, at least part of the second internal conductive column 02 is located between the conductive ring 10 and the first internal conductive column 01 and is electrically connected with the conductive ring 10 and the first internal conductive column 01 to realize signal transmission of the second internal conductive column 02 and the first internal conductive column 01. When the user touches the rotating button 100, the capacitance value change of the capacitor composed of the second internal conductive column 02 can be transmitted to the metal sheet 41 on the rotating wheel 40 through the first internal conductive column 01, and further transmitted to the display screen electrically connected with the rotating button 100. In this way, the electrical connection of at least part of the second internal conductive column 02 and the first internal conductive column 01, compared with the electronic device electrically connected with the rotating button 100 only through the weak change of the capacitor composed of the human body-outer top cover 21-second internal conductive column 02, the first internal conductive column 01 directly electrically connected with the second internal conductive column 02 can further conduct the change to the display screen through the metal sheet 41, the spring sheet 54, the metal pad 50, etc. Since the directly conducted signal has stronger recognition than the inductively obtained signal, when the human hand directly touches the outer top cover 21, the response sensitivity of the electronic screen to the rotating button 100 can also be improved.

[0059] Figure 8 Fig. 1 shows a connection diagram of a metal sheet, a spring sheet and a metal pad provided by an embodiment of the present disclosure, please refer to Figure 8 The present disclosure provides a rotating button 100, the base 60 includes m metal pads 50, m is a positive integer greater than or equal to 3; each metal pad 50 corresponds to a spring sheet 54; the number of metal sheets 41 is n, n is a positive integer greater than m.

[0060] Specifically, in an optional embodiment provided by the present disclosure, please refer to Figure 8 The base 60 includes three metal pads 50, and the metal pads 50 are located on the side of the base 60 away from the rotating wheel 40. Of course, in other embodiments, the base 60 can also include four, or five, or six, or other number of metal pads 50, which are not limited by the present disclosure, Figure 8Only taking the example of 3 metal pads 50 included in the rotary button 100. It should be noted that the base 60 further includes elastic sheets 54, the elastic sheets 54 are located on the side of the base 60 facing the rotating wheel 40, and the number of the elastic sheets 54 corresponds to the number of the metal pads 50 one by one, for example, when the number of the metal pads 50 on the base 60 is 3, the number of the elastic sheets 54 on the base 60 is also 3; when the number of the metal pads 50 on the base 60 is 4, the number of the elastic sheets 54 on the base 60 is also 4; when the number of the metal pads 50 on the base 60 is 5, the number of the elastic sheets 54 on the base 60 is also 5; and so on, which will not be listed one by one here, it is only necessary to know that the number of the elastic sheets 54 on the base 60 is equal to the number of the metal pads 50. Understandably, the elastic sheets 54 and the metal pads 50 at least partially overlap in projection on the base 60, and the elastic sheets 54 and the metal pads 50 that overlap in projection position are electrically connected, that is, the elastic sheets 54 and the metal pads 50 can realize signal conduction.

[0061] The metal sheet 41 is located on the side of the rotating wheel 40 bottom facing the base 60, in the process of rotating, the metal sheet 41 on the rotating wheel 40 contacts or does not contact the elastic sheet 54 on the side of the base 60 facing the rotating wheel 40, when the metal sheet 41 contacts the elastic sheet 54, the conduction of the touch signal can be realized, and further transmitted to the metal pad 50. In an optional embodiment provided by the present disclosure, the number of the metal sheet 41 is n, n is a positive integer greater than m, for example, when the number of the metal pad 50 is 3, the number of the metal sheet 41 is 4, or 5, or 6, or 7, and so on, the present disclosure does not limit the number of the metal sheet 41, only the number of the metal sheet 41 needs to satisfy the number of the metal pad 50, Figure 8 Only taking the example of 6 metal sheets 41 included in the rotary button 100. Understandably, the more the number of the metal sheet 41, the more the types of contact state generated when the metal sheet 41 contacts the elastic sheet 54, which can further subdivide the angle of rotation on the basis of distinguishing the direction of rotation of the rotary button 100, and improve the accuracy of identifying the angle of rotation. In this way, by setting the number of the metal pad 50 to be equal to the number of the elastic sheet 54, the signals received by the elastic sheet 54 when contacting the metal sheet 41 can all be conducted to the metal pad 50, reducing signal omission; by setting the number of the metal sheet 41 to be greater than the number of the elastic sheet 54, the types of contact state between the metal sheet 41 and the elastic sheet 54 can be increased, and the angle of rotation can be further subdivided to improve the accuracy of identifying the angle of rotation of the rotary button 100.

[0062] Please continue to refer to Figure 4 The present disclosure provides a rotary button 100, the width L of the conductive ring 10 is greater than 0 and less than or equal to 2.5 mm.

[0063] Specifically, in the direction parallel to the plane where the base 60 is located, the conductive ring 10 is located between the inner top cover 22 and the outer top cover 21, and the material of the conductive ring 10 includes but is not limited to metal or metal alloy, etc., which is not limited in the present disclosure. The width L of the conductive ring 10 is greater than 0 and less than or equal to 2.5 mm; optionally, the width L of the conductive ring 10 can be greater than 0 and less than or equal to 2 mm, or the width L of the conductive ring 10 can be greater than 0 and less than or equal to 1.5 mm, or the width L of the conductive ring 10 can be greater than 0 and less than or equal to 1 mm, etc., which is not limited in the present disclosure, as long as the width L of the conductive ring 10 is in the interval range of greater than 0 and less than or equal to 2.5 mm. When the width L of the conductive ring 10 is greater than 2.5 mm, the width L of the conductive ring 10 is too wide, resulting in an increase in production cost and an increase in the internal space of the rotary button 100, which is not conducive to the stability of the internal structure. Therefore, by setting the width L of the conductive ring 10 in the interval range of greater than 0 and less than or equal to 2.5 mm, the internal space of the rotary button 100 can be increased without increasing the internal space of the rotary button 100, which is conducive to the stability of the structure.

[0064] Figure 9 The structure of the electronic device provided by the embodiment of the present disclosure is shown in the structure schematic diagram of the electronic device provided by the embodiment of the present disclosure. Figures 4 to 9 The present disclosure provides an electronic device 300, which comprises a display panel 200 and a rotary button 100 provided by the present disclosure. One side of the base 60 of the rotary button 100 is fixed on the display panel 200. The display panel 200 comprises a touch layer 90, and the touch layer 90 comprises a plurality of arrayed touch electrodes 91. The display panel 200 detects the touch state and rotation state of the rotary button 100 through the capacitance difference between different touch electrodes 91 corresponding to different metal pads 50.

[0065] Specifically, in an optional embodiment provided by the present disclosure, the electronic device 300 comprises a display panel 200 and a rotary button 100. The rotary button 100 is fixed on the surface of the display panel 200 by adhesion or other methods. The rotary assembly 80 in the rotary button 100 can rotate relative to the fixed assembly 70.

[0066] The display panel 200 comprises a touch layer 90, the touch layer 90 comprises a plurality of touch electrodes 91 arranged in an array, and the display panel 200 further comprises a touch chip (not shown in the figure), which can be separately arranged or integrated in a driving chip, and the present disclosure does not make any limitation in this regard. During touch detection, the touch chip outputs a voltage to the touch electrodes 91, and the touch action of the user on the rotary button 100 causes the signal amount of the metal pad 50 in the rotary button 100 to change, so that the capacitance of the touch electrode 91 corresponding to the projection position of the metal pad 50 in the display panel 200 changes, thereby causing the voltage of the touch electrode 91 to change, so as to detect the touch action.

[0067] The touch electrode 91 can be a self-capacitance touch electrode or a mutual-capacitance touch electrode, and the present disclosure does not make any limitation in this regard. In an optional embodiment provided by the present disclosure, please refer to Figure 9 The rotary button 100 comprises a first metal pad 51, a second metal pad 52 and a third metal pad 53, the first touch electrode 92 corresponds to the projection position of the first metal pad 51, the second touch electrode 93 corresponds to the projection position of the second metal pad 52, and the third touch electrode 94 corresponds to the projection position of the third metal pad 53; when the user touches and rotates the rotary button 100, the display panel 200 scans the touch electrodes 91 row by row or column by column, and detects the capacitance values of the touch electrodes 91 respectively. For example, when the rotary button 100 rotates, the metal sheet 41 rotates accordingly, and whether the metal sheet 41 contacts the spring sheet 54 in the rotating process changes the capacitance of the first touch electrode 92 under the first metal pad 51, the capacitance of the second touch electrode 93 under the second metal pad 52, and the capacitance of the third touch electrode 94 under the third metal pad 53. If it is found that the capacitance value of a certain touch electrode 91 increases by an amount ΔC greater than a set threshold value, and the capacitance values of other touch electrodes 91 adjacent to the touch electrode 91 constitute a signal distribution curve, the peak value of the distribution curve is the touch center. The two-dimensional coordinates at the sub-pixel level are calculated by using an interpolation calculation method, and the two-dimensional coordinates are the touch point of the user on the rotary button 100.

[0068] It can be understood that the other film layer structures of the display panel 200 are the same as the film layer structures in the existing process, for example, the display panel 200 further comprises a substrate, an array layer, a light emitting element layer, etc., and will not be described in detail.

[0069] Please refer to Figure 4 and Figures 4 to 9The present disclosure provides an electronic device 300, when the outer top cover 21 is a metal material, the touch state only includes one touch state, in which the touch subject touches the outer top cover 21 or the conductive ring 10 of the rotary button 100; when the outer top cover 21 is an insulating material, the touch state includes a first touch state, a second touch state and a third touch state, in the first touch state, the touch subject touches the conductive ring 10 of the rotary button 100; in the second touch state, the touch subject touches the top cover 20 of the rotary button 100; in the third touch state, the touch subject touches the conductive ring 10 and the top cover 20 of the rotary button 100 at the same time.

[0070] Specifically, the touch subject can be a person or other living or non-living things that can touch and rotate the rotary button 100. In the first touch state, the touch subject only touches the conductive ring 10, and the touch signal can be transmitted to the electronic device 300 electrically connected to the rotary button 100 through path 1: human body-conductive ring 10-first internal conductive column 01-metal sheet 41-elastic sheet 54-metal pad 50, that is, path 1 is to transmit the touch signal through direct electrical conduction.

[0071] In the second touch state, the touch subject only touches the top cover 20, specifically, the touch subject can only touch the inner top cover 22 or the outer top cover 21, or the touch subject can touch the inner top cover 22 and the outer top cover 21 at the same time, which is not limited by the present disclosure; when the touch subject only touches the top cover 20, the layered structure of the top cover 20 makes the human body-top cover 20-second internal conductive column 02 form a first capacitor, so that the surface of the rotary button 100 has a corresponding electric field effect, when the human hand touches the top cover 20 on the rotary button 100, the capacitance value of the first capacitor changes, the touch signal can be transmitted through path 2: human body-top cover 20-second internal conductive column 02, and further transmitted to the display panel 200 electrically connected to the rotary button 100 through the first internal conductive column 01 electrically connected to the second internal conductive column 02, that is, path 2 is to transmit the touch signal through indirect electrical conduction.

[0072] In the third touch state, the touch body touches the top cover 20 and the conductive ring 10 at the same time. Specifically, the touch body can only touch the inner top cover 22 and the conductive ring 10, or the outer top cover 21 and the conductive ring 10, or the touch body can touch the top cover 20 and the conductive ring 10 at the same time, and the present disclosure does not make any limitation in this regard. As described above, when the touch body touches the top cover 20 and the conductive ring 10 at the same time, the signal generated by the touch body touching the conductive ring 10 is transmitted from path 1 to the display panel 200 electrically connected with the rotary button 100, and the signal generated by the touch body touching the top cover 20 is transmitted from path 2 through the first internal conductive column 01 and other components to the display panel 200 electrically connected with the rotary button 100, that is, in the third touch state, the touch signal can be transmitted through path 1 and path 2 at the same time. In this way, by designing different signal transmission paths according to different touch states of the touch body touching the rotary button 100, the various touch requirements that may exist in the touch body can be met. In addition, the sensing signal of the first capacitor formed by the human body-top cover 20-second internal conductive column 02 is further transmitted to the display panel 200 electrically connected with the rotary button 100 through the first internal conductive column 01, which can improve the sensitivity of signal transmission and reduce the transmission loss of the signal through direct electrical connection. Further, in the third touch state, the simultaneous transmission of path 1 and path 2 can increase the signal strength of the transmission and improve the recognition accuracy of the display panel 200 to the touch position of the rotary button 100.

[0073] Please continue to refer to Figure 4 The present disclosure provides an electronic device 300, the rotary button 100 includes a rotating wheel 40, the rotating wheel 40 includes a plurality of metal sheets 41, and the plurality of metal sheets 41 are arranged at equal intervals along the circumferential direction of the rotating wheel 40; the base 60 includes a plurality of elastic sheets 54, and the elastic sheet 54 is fixed to one side of the base 60 facing the rotating wheel 40; in the rotating state, the rotating signal of the rotary button 100 transmitted by the touch electrode 91 is related to the contact state of the metal sheet 41 and each elastic sheet 54.

[0074] Specifically, please refer to Figure 9 and Figure 10 The elastic sheet 54 is located on one side of the base 60 facing the rotating wheel 40, the metal sheet 41 is located on one side of the rotating wheel 40 facing the base 60, the position of the elastic sheet 54 on the base 60 is fixed, the base 60 is fixed on the display panel 200, and when the rotating assembly 80 in the rotary button 100 rotates relative to the fixed assembly 70, the metal sheet 41 will rotate together with the rotating wheel 40, and in the process of rotation, the metal sheet 41 will be in contact or not in contact with the elastic sheet 54 on the base 60, thereby forming different contact states and generating different rotating signals.

[0075] In an optional embodiment provided by the present disclosure, the elastic sheet 54 includes a first elastic sheet 55, a second elastic sheet 56, and a third elastic sheet 57. The first elastic sheet 55 is electrically connected to the first metal pad 51, the second elastic sheet 56 is electrically connected to the second metal pad 52, and the third elastic sheet 57 is electrically connected to the third metal pad 53. Whether the metal sheet 41 contacts the first elastic sheet 55, the second elastic sheet 56, or the third elastic sheet 57 during rotation will cause the signal quantity of the metal pad 50 in the rotary button 100 to change, further changing the capacitance of the first touch electrode 92 below the first metal pad 51, changing the capacitance of the second touch electrode 93 below the second metal pad 52, and changing the capacitance of the third touch electrode 94 below the third metal pad 53. The sequence of signal quantity changes of the metal pad 50 at different positions when the rotary button 100 is rotated clockwise is different from the sequence of signal quantity changes of the metal pad 50 at different positions when the rotary button 100 is rotated counterclockwise. In this way, by arranging the metal sheets 41 at equal intervals along the circumferential direction of the rotating wheel 40, the metal sheets 41 can produce different contact states with the elastic sheet 54 during rotation. The rotary signal sensed by the touch electrode 91 in the display panel 200 electrically connected to the rotary button 100 is different under different contact states, and accordingly the rotation state of the rotary button 100 can be determined.

[0076] It should be noted that the touch electrode 91 can be a self-capacitance touch electrode or a mutual-capacitance touch electrode. Understandably, the detection methods of these two types of touch electrodes are the same as the prior art principles, and will not be described again.

[0077] Figure 11 FIG. 7 shows a step diagram of a rotation determination method of a rotary button provided by an embodiment of the present disclosure, Figures 9 to 11 FIG. 8 shows a voltage waveform diagram in a display panel provided by an embodiment of the present disclosure. Please refer to Figure 11 The present disclosure provides a rotation determination method of a rotary button 100, which is applied to an electronic device 300 provided by the present disclosure, including the following steps. Step S1: detecting a received voltage on a display panel 200. During touch detection, a touch chip outputs a voltage to a touch electrode 91 on the display panel 200, and then detects a voltage value returned on the touch electrode 91. The voltage value returned on the touch electrode 91 is the received voltage. Step S2: determining whether the received voltage is less than a set threshold range. Step S3: if yes, identifying the rotation direction and / or angle of the rotary button 100; if no, considering that there is no touch, and determining that the rotary button 100 is not rotating.

[0078] Specifically, in step S1, the touch state of the touch electrode 91 in the display panel 200 is detected. For example, please refer to Figure 12, the vertical coordinate is voltage value, unit is V, the horizontal coordinate is time, unit is ms, wherein, the first curve C1 is the voltage simulation waveform outputted by the touch chip to the touch electrode 91 on the display panel 200, the voltage of the first curve C1 is in the interval range of (-6V, 6V), taking the voltage value of the first curve C1 as the reference, the received voltage of the touch electrode 91 on the display panel 200 is detected; the second curve C2 is the simulation waveform detected by the rotary button 100 in the non-touch state, the voltage of the second curve C2 is in the interval range of (-4V, 4V); the third curve C3 is the simulation waveform of the rotary button 100 transmitting the touch signal through the path 2, the voltage of the third curve C3 is in the interval range of (-3V, 3V); the fourth curve C4 is the simulation waveform of the rotary button 100 transmitting the touch signal through the path 1, the voltage of the fourth curve C4 is in the interval range of (-2V, 2V). It can be understood that there may also be a fifth curve (not shown in the figure) in the actual operation process, the fifth curve is the simulation waveform of the rotary button 100 transmitting the touch signal through the path 1 and the path 2 at the same time, and the absolute value of the voltage of the fifth curve is less than the absolute value of the voltage of the second curve C2 in the non-touch state.

[0079] The absolute values of the voltages of the second curve C2, the third curve C3, the fourth curve C4 and the fifth curve are all less than the absolute value of the voltage of the first curve C1. Further, the absolute values of the voltages of the third curve C3, the fourth curve C4 and the fifth curve are all less than the absolute value of the voltage of the second curve C2, that is, the absolute value of the voltage received by the touch electrode 91 of the rotary button 100 in the touch state is less than the absolute value of the voltage received by the touch electrode 91 of the rotary button 100 in the non-touch state.

[0080] Therefore, whether the rotary button 100 is in the touch state or not can be judged according to the received voltage of the touch electrode 91 by setting the threshold range, in step S2, the threshold range includes the threshold control upper limit R1 and the threshold control lower limit R2, the threshold control upper limit R1 and the threshold control lower limit R2 are both parallel to the horizontal coordinate of the above-mentioned curve, the threshold control upper limit R1 and the threshold control lower limit R2 respectively intersect with the second curve C2, the vertical coordinate of the threshold control upper limit R1 is slightly less than the highest point of the second curve C2, and the vertical coordinate of the threshold control lower limit R2 is slightly greater than the highest point of the second curve C2, in this way, when the received voltage of the touch electrode 91 is detected, the received voltage between the threshold control upper limit R1 and the threshold control lower limit R2 can be judged as the voltage when the rotary button 100 is in the touch state, and the received voltage outside the threshold control upper limit R1 and the threshold control lower limit R2 can be judged as the voltage when the rotary button 100 is in the non-touch state.

[0081] It should be noted that the ordinate of the threshold upper limit R1 should be greater than the highest point of the third curve C3, the fourth curve C4 and the fifth curve, and the ordinate of the threshold lower limit R2 should be less than the lowest point of the third curve C3, the fourth curve C4 and the fifth curve. The present disclosure does not limit the voltage value of the threshold upper limit R1 and the threshold lower limit R2, and the specific value can be set according to the actual situation.

[0082] In step S3, when the receiving voltage of the touch electrode 91 is less than the threshold range set by the threshold upper limit R1 and the threshold lower limit R2, the rotation direction and angle of the rotary button 100 are further identified, such as clockwise rotation or counterclockwise rotation, and the rotation angle in different rotation directions; when the receiving voltage of the touch electrode 91 is not within the threshold range set by the threshold upper limit R1 and the threshold lower limit R2, it is determined that the rotary button 100 is in a non-touch state.

[0083] In this way, by the above-mentioned rotation determination method and the set threshold range, it can be determined whether the rotary button 100 is in a touch state or a non-touch state by detecting the receiving voltage of the touch electrode 91. The determination method is simple and direct, and the corresponding speed is fast. The threshold voltage range can also be flexibly set according to the actual working condition of the electronic device 300, and can adapt to various application scenarios.

[0084] Figures 9 to 12 The figure shows a step diagram for identifying the rotation direction and angle of the rotary button provided by the embodiment of the present disclosure. Please refer to Figure 13 The present disclosure provides a rotation determination method for a rotary button 100. In step S3, the rotation direction and angle of the rotary button 100 are identified, including: step S31, scanning the touch electrode 91 to detect the capacitance value change of each metal pad 50 corresponding position; step S32, judging the touch position on the rotary button 100 according to the capacitance value change of the metal pad 50; step S33, judging the rotation direction and / or angle of the rotary button 100 according to the signal amount change of each metal pad 50 at adjacent time.

[0085] Specifically, in step S31, the touch electrode 91 is scanned row by row or column by column to detect the capacitance value of the touch electrode 91 corresponding to each metal pad 50. Optionally, when the touch electrode 91 is a self-capacitance touch electrode, it is assumed that the rotary button 100 includes three metal pads 50, and the capacitance value change of the touch electrode 91 under each metal pad 50 is detected. Optionally, when the touch electrode 91 is a self-capacitance touch electrode, the touch state can be directly judged by the capacitance value change of the touch electrode 91 under each metal pad 50. When the touch electrode 91 is a mutual-capacitance touch electrode, the touch state can be judged by the capacitance difference between the transmitting electrode and the receiving electrode in the touch electrode 91 under each metal pad 50.

[0086] In step S32, the capacitance value change detected in step S31 is compared with a first threshold value. It is found that the increase in the capacitance value of a certain touch electrode 91 is greater than the first threshold value, and the increase in the capacitance value of the adjacent touch electrode 91 constitutes a signal distribution curve. The peak value of the signal distribution curve is the touch center. The sub-pixel two-dimensional coordinates are calculated by using the difference calculation method. The two-dimensional coordinates are the touch position of the rotary button 100.

[0087] Figure 14 Fig. 2 shows a step diagram for judging the rotation direction and angle of a rotary button according to an embodiment of the present disclosure, Figure 15 Fig. 3 shows a contact state diagram of a metal sheet and an elastic sheet in a rotary button according to an embodiment of the present disclosure, Figure 14 Fig. 4 shows a signal amount change diagram of a rotary button in Fig. 1, Figures 9 to 15 Fig. 5 shows a signal amount change diagram of a rotary button in Fig. 2, Figure 14 In step S33, the rotation direction and angle of the rotary button 100 are judged according to the signal amount changes of the metal pads 50 at adjacent time points. The step S33 includes the following steps. In step S331, it is determined that the contact between the elastic sheet 54 corresponding to any metal pad 50 and the metal sheet 41 is logic 1, and the disconnection between the elastic sheet 54 corresponding to any metal pad 50 and the metal sheet 41 is logic 0. In step S332, the number of signal amounts of the rotary button 100 is obtained as 2m according to the number m of metal pads 50 and the logic state of each metal pad 50. In step S333, it is determined that the rotary button 100 rotates forward when the signal amount changes in a first order, and reverses when the signal amount changes in a second order. The second order is the reverse order of the first order. In step S334, the rotation angle of the rotary button 100 is determined according to the number of signal amount changes in one rotation operation. m , m is a positive integer greater than or equal to 3. In step S333, it is determined that the rotary button 100 rotates forward when the signal amount changes in a first order, and reverses when the signal amount changes in a second order. The second order is the reverse order of the first order. In step S334, the rotation angle of the rotary button 100 is determined according to the number of signal amount changes in one rotation operation.

[0088] Specifically, in an optional embodiment provided by the present disclosure, when the rotary button 100 includes 6 metal sheets 41 and 3 elastic sheets 54, there are various contact states between the metal sheets 41 and the elastic sheets 54 during the rotation of the rotary button 100. For example, Figure 15 and Figure 15, 3 elastic sheets 54 are respectively a first elastic sheet 55, a second elastic sheet 56 and a third elastic sheet 57, wherein the first elastic sheet 55 corresponds to the first metal pad 51, the second elastic sheet 56 corresponds to the second metal pad 52, and the third elastic sheet 57 corresponds to the third metal pad 53, the contact state of the rotary button 100 includes 8 signal amounts: in the first contact state J1, the metal sheet 41 contacts the first elastic sheet 55, the metal sheet 41 contacts the second elastic sheet 56, and the metal sheet 41 contacts the third elastic sheet 57; in the second contact state J2, the rotary button 100 is rotated clockwise, the metal sheet 41 contacts the first elastic sheet 55, the metal sheet 41 contacts the second elastic sheet 56, and the metal sheet 41 does not contact the third elastic sheet 57; in the third contact state J3, the rotary button 100 is rotated clockwise, the metal sheet 41 contacts the first elastic sheet 55, the metal sheet 41 does not contact the second elastic sheet 56, and the metal sheet 41 contacts the third elastic sheet 57; in the fourth contact state J4, the rotary button 100 is rotated clockwise, the metal sheet 41 contacts the first elastic sheet 55, the metal sheet 41 does not contact the second elastic sheet 56, and the metal sheet 41 does not contact the third elastic sheet 57; in the fifth contact state J5, the rotary button 100 is rotated clockwise, the metal sheet 41 does not contact the first elastic sheet 55, the metal sheet 41 contacts the second elastic sheet 56, and the metal sheet 41 contacts the third elastic sheet 57; in the sixth contact state J6, the rotary button 100 is rotated clockwise, the metal sheet 41 does not contact the first elastic sheet 55, the metal sheet 41 contacts the second elastic sheet 56, and the metal sheet 41 does not contact the third elastic sheet 57; in the seventh contact state J7, the rotary button 100 is rotated clockwise, the metal sheet 41 does not contact the first elastic sheet 55, the metal sheet 41 does not contact the second elastic sheet 56, and the metal sheet 41 contacts the third elastic sheet 57; in the eighth contact state J8, the rotary button 100 is rotated clockwise, the metal sheet 41 does not contact the first elastic sheet 55, the metal sheet 41 does not contact the second elastic sheet 56, and the metal sheet 41 does not contact the third elastic sheet 57.

[0089] Please refer to ​The signal quantity of the rotary button 100 is sequentially changed from the first contact state J1 to the second contact state J2, the third contact state J3, the fourth contact state J4, the fifth contact state J5, the sixth contact state J6, the seventh contact state J7, and the eighth contact state J8 at adjacent time points as a first order, i.e., a positive order. Of course, the signal quantity of the rotary button 100 does not have to be sequentially changed from the first contact state J1 to the eighth contact state J8 at adjacent time points, but can be changed from the first contact state J1 to the second contact state J2 only, or from the fifth contact state J5 to the sixth contact state J6 only, and the like, which is not limited in the present disclosure, as long as the first order is the sequential change of the above eight contact states. The logic symbol corresponding to the above eight contact states is the signal quantity of the rotary button 100 in the rotation process, and the rotation of the rotary button 100 is determined to be positive rotation when the signal quantity changes in the first order, i.e., the contact state of the rotary button 100 changes in the first order, and the rotation of the rotary button 100 is determined to be reverse rotation when the signal quantity changes in the second order, i.e., the contact state of the rotary button 100 changes in the reverse order of the first order.

[0090] In step S334, as described above, when the rotary button 100 includes only three metal pads 50, the rotation of the rotary button 100 will generate eight changes in contact states, and the rotation angle of the rotary button 100 can be calculated according to the number of signal quantity changes in one rotation operation and the gear set by the rotary button 100. For example, the angle change of one rotation is 360°, the gear of the rotary button 100 is 24, and the signal quantity changes five times when the rotary button 100 rotates once. Therefore, the rotation angle of the rotary button 100 is 360° ÷ 24 × 5 = 75°. The above is only an example of the rotary button 100 including three metal pads 50 and the gear being 24, and the signal quantity changing five times when the rotary button 100 rotates once. It can be understood that different rotary buttons 100 can have other gears according to different user needs when initially designed, such as a gear of 32, and the like, which is not limited in the present disclosure. Similarly, the number of metal pads 50 or spring sheets 54 of different rotary buttons 100 can also be more than three when initially designed, which is not limited in the present disclosure. Accordingly, the change in the number of metal pads 50 or spring sheets 54 can cause the signal quantity of the rotary button 100 to change, which will not be described again.

[0091] In the above eight contact states, the capacitance of the touch electrode 91 under the first metal pad 51, the touch electrode 91 under the second metal pad 52, and the touch electrode 91 under the third metal pad 53 varies respectively. It can be understood that, no matter which contact state the rotary button 100 is in, the contact state switched by the rotary button 100 after the rotary button 100 is rotated once clockwise or once counterclockwise is different. For example, assuming that the rotary button 100 is in the first contact state J1 in the current state, if the rotary button 100 is rotated once clockwise in the current state, the rotary button 100 switches to the second contact state J2, and if the rotary button 100 is rotated once counterclockwise in the current state, the rotary button 100 switches to the eighth contact state J8.

[0092] Therefore, the rotation direction and the rotation angle of the rotary button 100 can be determined by detecting the rotation signals containing the capacitance information fed back by the touch electrodes 91 under the different metal pads 50.
