[0021] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0022] See also Figure 1 , Figure 1 The figure is a flow chart of an embodiment of the identification method for detecting the manipulation of a magnetic control button of the present application. The execution subject of the identification method for detecting the manipulation of a magnetic control button of the present application is a magnetic touch panel.

[0023] See also Figure 2 The magnetic touch panel 1000 includes a touch substrate 1100, a plurality of gear / function sensing electrodes 1200, a storage device 1300 and a processing device 1400. The plurality of gear / function sensing electrodes 1200 are arranged on the same side of the touch substrate 1100. At the same time, the side of the touch substrate 1100 where the plurality of gear / function sensing electrodes 1200 are not arranged is used for placing a magnetic control button 2000.

[0024] Among them, the magnetic control button 2000 is adsorbed on the touch substrate 1100 by magnetic attraction. Such a setting can realize relevant operations through the magnetic control button 2000 without cutting grooves on the touch substrate 1100. It is beautiful, practical and waterproof. When the accumulated oil needs to be cleaned, the magnetic control button 2000 can be directly removed from the touch substrate 1100, which can maintain the beauty to the greatest extent and bring better user experience.

[0025] Combination Figure 3 The magnetic control button 2000 includes a gear position / function selection sensing block 2110 , wherein the material of the gear position / function selection sensing block 2110 is metal, and the gear position / function selection sensing block 2110 corresponds to a plurality of gear position / function sensing electrodes 1200 .

[0026] Specifically, the multiple gear / function sensing electrodes 1200 in the magnetic touch panel 1000 are used to sense the manipulation of the gear / function selection sensing block 2110 in the magnetic control button 2000 and generate corresponding sensing values. At the same time, the multiple gear / function sensing electrodes 1200 correspond to different gears or different execution functions. When the user manipulates the magnetic control button 2000 to change the position of the gear / function selection sensing block 2110, the target gear / function sensing electrode 1200 is selected, thereby realizing the selection of function or gear.

[0027] Among them, the control method of the magnetic control button 2000 in the present application is that the user changes the position of the gear / function selection sensing block 2110 after contacting the gear / function selection sensing block 2110, and the whole working principle is to utilize the capacitive sensing effect between the gear / function selection sensing block 2110 and the gear / function sensing electrode 1200.

[0028] The storage device 1300 stores a program, and the processing device 1400 is connected to the storage device 1300 and the plurality of gear / function sensing electrodes 1200 to retrieve the program stored in the storage device 1300 and execute the identification method for detecting the manipulation of the magnetic control button in the present application.

[0029] Continue reading Figure 1 , the identification method includes:

[0030] S110 : Detecting the sensing values ​​of the plurality of gear / function sensing electrodes 1200 to determine whether the sensing value of at least one gear / function sensing electrode 1200 changes in the first direction or the second direction by a value greater than a first threshold.

[0031] S120: When it is determined that the sensing value of at least one gear / function sensing electrode 1200 changes in the first direction or the second direction by more than the first threshold value, a corresponding recognition instruction is generated, wherein the recognition instruction includes a first recognition instruction indicating that the magnetic control button 2000 is placed on the magnetic touch panel 1000 and / or a second recognition instruction indicating that the magnetic control button 2000 is removed from the magnetic touch panel 1000.

[0032] When a magnetic control button 2000 is placed on the magnetic touch panel 1000, due to the capacitive sensing effect between the gear / function selection sensing block 2110 and the gear / function sensing electrode 1200, the sensing value of at least one gear / function sensing electrode 1200 will change in one direction by a value greater than the first threshold value, and a mutation will be formed compared to when the magnetic control button 2000 is not placed. When the magnetic control button 2000 is removed from the magnetic touch panel 1000, also due to the capacitive sensing effect, the sensing value of at least one gear / function sensing electrode 1200 will also change in one direction by a value greater than the first threshold value, and a mutation will be formed compared to when the magnetic control button 2000 is placed on the magnetic touch panel 1000.

[0033] In the above embodiment, by utilizing the change in the sensing value of at least one gear / function sensing electrode 1200 according to the capacitive sensing effect, it is determined whether the magnetic control button 2000 is placed on the magnetic touch panel 1000 or removed from the magnetic touch panel 1000. This can determine the state of the magnetic control button 2000 without adding additional components, thus avoiding additional costs.

[0034] In this embodiment, when it is determined that the sensing value of at least one gear / function sensing electrode 1200 changes in a first direction greater than a first threshold, a first recognition instruction is generated; or, when it is determined that the sensing value of at least one gear / function sensing electrode 1200 changes in a second direction greater than the first threshold, a second recognition instruction is generated.

[0035] It is understandable that when the magnetic control button 2000 is placed on the magnetic touch panel 1000, the direction of change of the sensing value generated by the gear / function sensing electrode 1200 is opposite to the direction of change of the sensing value generated when the magnetic control button 2000 is removed. Figure 4 and Figure 5 .

[0036] Therefore, in an application scenario, when the magnetic control button 2000 is placed, the direction of change of the sensing value generated by at least one gear / function sensing electrode 1200 is positive, and when the magnetic control button 2000 is removed, the direction of change of the sensing value generated by at least one gear / function sensing electrode 1200 is negative.

[0037] That is to say, in this application scenario, the first direction is the positive direction, that is, when the increase in the sensing value of at least one gear / function sensing electrode 1200 is greater than the first threshold, a first recognition instruction is generated indicating that the magnetic control button 2000 is placed on the magnetic touch panel 1000; the second direction is the negative direction, that is, when the decrease in the sensing value of at least one gear / function sensing electrode 1200 is greater than the first threshold, a second recognition instruction is generated indicating that the magnetic control button 2000 is removed from the magnetic touch panel 1000.

[0038] In this embodiment, combined with Figure 4 and Figure 5 , step S110 further specifically includes: detecting the sensing values ​​of the plurality of gear / function sensing electrodes 1200 to determine whether the sensing values ​​of the first gear / function sensing electrode 1210 and the second gear / function sensing electrode 1220 change in the first direction or the second direction that is greater than the first threshold value; wherein the first gear / function sensing electrode 1210 is adjacent to the second gear / function sensing electrode 1220, and when the placed or removed magnetic control button 2000 is placed on the magnetic touch panel 1000, the projection of the gear / function selection sensing block 2110 on the magnetic touch panel 1000 at least partially overlaps the area between the first gear / function sensing electrode 1210 and the second gear / function sensing electrode 1220.

[0039] Specifically, when the magnetic control button 2000 is placed on the magnetic touch panel 1000, the gear position / function selection sensing block 2110 is placed adjacent to two adjacent gear position / function sensing electrodes 1200 at the same time with a high probability: in one case, the projection of the gear position / function selection sensing block 2110 on the magnetic touch panel 1000 is entirely between the adjacent first gear position / function sensing electrode 1210 and the second gear position / function sensing electrode 1220; in the second case, a portion of the projection of the gear position / function selection sensing block 2110 on the magnetic touch panel 1000 is between the adjacent first gear position / function sensing electrode 1210 and the second gear position / function sensing electrode 1220. The gear position / function sensing electrodes 1220 have another part overlapping with the first gear position / function sensing electrode 1210 and / or the second gear position / function sensing electrode 1220. At this time, when the magnetic control button 2000 is placed or removed, the sensing values ​​of the first gear position / function sensing electrode 1210 and the second gear position / function sensing electrode 1220 will both have a change greater than the first threshold value. Therefore, in order to ensure the accuracy of recognition, it is necessary to determine the state of the magnetic control button 2000 through the change in the sensing values ​​of the adjacent first gear position / function sensing electrode 1210 and the second gear / function sensing electrode 1220.

[0040] The closer the gear / function sensing electrode 1200 is to the gear / function selection sensing block 2110, the greater the change in its sensing value. Figure 4 and Figure 5 In the application scenario, the first gear position / function sensing electrode 1210 is closer to the gear position / function selection sensing block 2110 than the second gear position / function sensing electrode 1220. Therefore, when the magnetic control button 2000 is placed or removed, the change in the sensing value on the first gear position / function sensing electrode 1210 is greater than the change in the sensing value on the second gear position / function sensing electrode 1220.

[0041] At the same time Figure 4 and Figure 5 In the application scenario, when the magnetic control button 2000 is placed or removed, except for the first gear / function sensing electrode 1210 and the second gear / function sensing electrode 1220, the sensing values ​​of the remaining gear / function sensing electrodes 1200 will also change in the first direction or the second direction, but the changes are not large and will not exceed the first threshold.

[0042] In other embodiments, when the magnetic control button 2000 can be placed on the magnetic touch panel 1000, and the gear / function selection sensing block 2110 is set opposite to a gear / function sensing electrode 1200, step S110 can specifically be: detecting the sensing values ​​of multiple gear / function sensing electrodes 1200 to determine whether there is a gear / function sensing electrode 1200 whose sensing value changes in the first direction or the second direction greater than the first threshold.

[0043] In this embodiment, the first threshold exceeds the background noise by more than 20%.

[0044] Specifically, when the user manipulates the magnetic control button 2000 to select a gear / function, the sensing value generated by the selected gear / function sensing electrode 1200 will change, and although the sensing value generated by the unselected gear / function sensing electrode 1200 may also change, the amount of change will not exceed the amount of change generated by the selected gear / function sensing electrode 1200. That is to say, when the user selects a gear / function, the change in the sensing value generated by the selected gear / function sensing electrode 1200 is the largest, but there is also an upper limit to the change, where the upper limit is defined as the background noise. That is to say, the background noise is the maximum change in the sensing value generated by the selected gear / function sensing electrode 1200 when the user manipulates the magnetic control button 2000 to select a gear / function.

[0045] In order to exclude the possibility that the sensing value of at least one gear / function sensing electrode 1200 changes in the first direction or the second direction by more than the first threshold value due to the user operating the magnetic control button 2000 to select the gear / function, the first threshold value is set to exceed the background noise by more than 20%, for example, the first threshold value exceeds the background noise by 20%, 30% or 40%.

[0046] In this embodiment, the identification method further includes:

[0047] S130: Detecting the sensing value of the auxiliary function sensing electrode 1500 to determine whether the sensing value changes in the first direction or the second direction by a value greater than a second threshold.

[0048] S140: When it is determined that the sensing value of the auxiliary function sensing electrode 1500 changes in the first direction or the second direction by a value greater than the second threshold, a corresponding auxiliary identification instruction is generated, wherein the auxiliary identification instruction includes a first auxiliary identification instruction indicating that the magnetic control button 2000 is placed on the magnetic touch panel 1000 and / or a second auxiliary identification instruction indicating that the magnetic control button 2000 is removed from the magnetic touch panel 1000.

[0049] In one embodiment, if Figure 3 As shown, the magnetic control button 2000 includes an auxiliary key 2200 in addition to the gear / function selection sensor block 2110. The magnetic control button 2000 further includes: a conductive ring 2100, a first magnetic member 2300, a first insulating ring 2400 and a second insulating ring 2500.

[0050] The gear position / function selection sensing block 2110 is convexly arranged on the inner wall of the conductive ring 2100 and connected to the conductive ring 2100. The material of the conductive ring 2100 is a conductive material, such as metal. In an application scenario, the gear position / function selection sensing block 2110 and the conductive ring 2100 are integrally formed. The auxiliary key 2200 includes a cap 2210 and a rod 2220 convexly arranged on the cap 2210. The cap 2210 is used to contact the user's hand. The rod 2220 passes through the first insulating ring 2400, the conductive ring 2100 and the second insulating ring 2500 in sequence. And it contacts the touch substrate 1100, specifically, the end face of the rod portion 2220 away from the cap portion 2210 contacts the touch substrate 1100, and the rod portion 2220 is a hollow structure, which is provided with a groove (not shown in the figure), and the first magnetic member 2300 is accommodated in the groove. The first magnetic member 2300 and the second magnetic member (not shown in the figure) in the magnetic touch panel 1000 attract each other so that the magnetic control button 2000 is adsorbed on the touch substrate 1100, and the first insulating ring 2400 and the second insulating ring 2500 are used to isolate the conductive ring 2100 and the auxiliary key 2200.

[0051] The first magnetic component 2300 in the magnetic control button 2000 and the second magnetic component in the magnetic touch panel 1000 may be a pair of magnets that attract each other, or one may be a magnet and the other may be a metal component that can be attracted by the magnet.

[0052] See also Figure 2 , corresponding to the auxiliary key 2200 in the magnetic control button 2000, there is an auxiliary function sensing electrode 1500 in the magnetic touch panel 1000, and the auxiliary function sensing electrode 1500 and the gear / function sensing electrode 1200 are located on the same side of the touch substrate 1100, and are used to sense the control on the auxiliary key 2200 in the magnetic control button 2000 and generate corresponding sensing values.

[0053] In one application scenario, Figure 3 In the magnetic control button 2000, the user first changes the state of the gear / function selection sensing block 2110 by rotating the conductive ring 2100, thereby selecting a plurality of gear / function sensing electrodes 1200. At the same time, after the user selects the gear / function, the user will also confirm by touching the auxiliary key 2200, and then the device will adjust the corresponding gear / function. That is to say, at this time the auxiliary key 2200 is a confirmation key, and the user confirms by operating the auxiliary key 2200. Specifically, when the user operates the auxiliary key 2200, the auxiliary function sensing electrode 1500 is triggered, and then a corresponding confirmation recognition instruction is generated.

[0054] In another application scenario, the user can also cancel, pause, and other operations by operating the auxiliary key 2200. For example, when the device is running, the user can pause the device by operating the auxiliary key 2200. Or, after the user selects a gear or a function, the user can cancel the previous gear or function selection by operating the auxiliary key 2200.

[0055] In summary, this application does not limit the function of the auxiliary key 2200.

[0056] As for the auxiliary function sensing electrode 1500, when the magnetic control button 2000 is placed or removed, Figure 6 and Figure 7As shown, due to the capacitive sensing effect between the auxiliary function sensing electrode 1500 and the auxiliary key 2200, the change in the sensing value on the auxiliary function sensing electrode 1500 is a fixed value. Therefore, this embodiment uses the change in the sensing value of the auxiliary function sensing electrode 1500 to perform auxiliary identification, which can avoid the sensing value of at least one gear / function sensing electrode 1200 from changing in the first direction or the second direction greater than the first threshold value not because the magnetic control button 2000 is taken or placed but due to interference from external factors (for example, oil stains are generated on the magnetic control button 2000), thereby ensuring the accuracy of identification.

[0057] In this embodiment, when it is determined that the sensing value of the auxiliary function sensing electrode 1500 changes in the first direction by more than the second threshold, a first auxiliary instruction is generated; or, when it is determined that the sensing value of the auxiliary function sensing electrode 1500 changes in the second direction by more than the second threshold, a second auxiliary instruction is generated.

[0058] The change direction of the sensing value of the gear position / function sensing electrode 1200 is the same as that of the sensing value of the auxiliary function sensing electrode 1500 . When the magnetic control button 2000 is placed or removed, the change direction of the sensing value of the auxiliary function sensing electrode 1500 is opposite.

[0059] In this embodiment, the second threshold is equal to the first threshold. In other embodiments, the second threshold may also be different from the first threshold, which is not limited here.

[0060] It should be noted that the above combination Figure 3 The structure of the magnetic control button 2000 illustrates the identification method of the present application, but the identification method of the present application can also be applied to magnetic control buttons of other structures, that is, the present application does not limit the specific structure of the magnetic control button.
