All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, fig. 1 is a schematic flow chart of an embodiment of an identification method for detecting manipulation of a magnetically attracting manipulation button according to the present application. The execution main body of the identification method for detecting the manipulation of the magnetic suction control button is a magnetic suction touch panel.
Referring to fig. 2, the magnetic attraction touch panel 1000 includes a touch substrate 1100, a plurality of shift/function sensing electrodes 1200, a storage device 1300 and a processing device 1400, wherein the plurality of shift/function sensing electrodes 1200 are disposed on the same side of the touch substrate 1100, and meanwhile, the side of the touch substrate 1100 not disposed with the plurality of shift/function sensing electrodes 1200 is used for placing the magnetic attraction control button 2000.
Wherein, this magnetism is inhaled and is controlled button 2000 and adsorbed on touch-control base plate 1100 through the mode of magnetism, and such setting can need not the fluting and control button 2000 and realize relevant controlling by magnetism on touch-control base plate 1100, and pleasing to the eye practicality, and waterproof, and when needing to clean the greasy dirt of accumulation, can directly inhale magnetism and control button 2000 and take away from touch-control base plate 1100, can keep pleasing to the eye to the greatest extent, bring better use experience for the user.
Referring to fig. 3, the magnetically operated button 2000 includes a gear/function selection sensing block 2110, wherein the gear/function selection sensing block 2110 is made of metal, and the gear/function selection sensing block 2110 corresponds to the plurality of gear/function sensing electrodes 1200.
Specifically, the plurality of gear/function sensing electrodes 1200 in the magnetic touch panel 1000 are used for sensing the manipulation on the gear/function selection sensing block 2110 in the magnetic manipulation button 2000 to generate corresponding sensing values, and meanwhile, the plurality of gear/function sensing electrodes 1200 correspond to different gears or different execution functions, when the user manipulates the magnetic manipulation 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 the function or the gear.
In the present application, the magnetic control button 2000 is controlled by a user contacting the gear/function selection sensing block 2110 to change the position of the gear/function selection sensing block 2110, and the whole operation principle is to use the capacitive sensing effect between the gear/function selection sensing block 2110 and the gear/function sensing electrode 1200.
The storage device 1300 stores programs, and the processing device 1400 is connected to the storage device 1300 and the plurality of gear/function sensing electrodes 1200 to retrieve the programs stored in the storage device 1300 to execute the identification method for detecting manipulation of the magnetic control button in the present application.
With continued reference to fig. 1, the identification method includes:
s110: the sensing values of the plurality of gear/function sensing electrodes 1200 are detected to determine whether the sensing value of at least one gear/function sensing electrode 1200 changes in a first direction or a second direction larger than a first threshold.
S120: when it is determined that the sensing value of at least one gear/function sensing electrode 1200 changes in a direction greater than the first threshold value in the first direction or the second direction, a corresponding recognition instruction is generated, where the recognition instruction includes a first recognition instruction indicating that the magnetically attracting control button 2000 is placed on the magnetically attracting touch panel 1000 and/or a second recognition instruction indicating that the magnetically attracting control button 2000 is taken away from the magnetically attracting touch panel 1000.
When the magnetically attractive operation button 2000 is placed on the magnetically attractive 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 a direction greater than the first threshold value, and compared to when the magnetically attractive operation button 2000 is not placed, a sudden change will be formed, and when the magnetically attractive operation button 2000 is taken away from the magnetically attractive touch panel 1000, due to the capacitive sensing effect, the sensing value of at least one gear/function sensing electrode 1200 will also change in a direction greater than the first threshold value, and compared to when the magnetically attractive operation button 2000 is placed on the magnetically attractive touch panel 1000, a sudden change will also be formed.
In the above embodiment, the change of the sensing value of the at least one shift/function sensing electrode 1200 is used to determine whether the magnetically attractive operation button 2000 is placed on the magnetically attractive touch panel 1000 or removed from the magnetically attractive touch panel 1000 according to the capacitive sensing effect, so that the state of the magnetically attractive operation button 2000 can be determined without adding additional components, thereby avoiding additional cost.
In this embodiment, when it is determined that the sensing value of at least one shift position/function sensing electrode 1200 changes in the first direction by more than a first threshold value, a first recognition command is generated; alternatively, the second recognition instruction is generated when it is determined that the sensing value of at least one position/function sensing electrode 1200 varies in the second direction more than the first threshold value.
It can be understood that, when the magnetically attracting control button 2000 is placed on the magnetically attracting touch panel 1000, the change direction of the sensing value generated by the shift/function sensing electrode 1200 is opposite to the change direction of the sensing value generated when the magnetically attracting control button 2000 is taken away, which can be seen in fig. 4 and 5.
Therefore, in an application scenario, when the magnetic attraction control button 2000 is placed, the variation direction of the sensing value generated by the at least one gear/function sensing electrode 1200 is set to be a positive direction, and when the magnetic attraction control button 2000 is taken away, the variation direction of the sensing value generated by the at least one gear/function sensing electrode 1200 is set to be a negative direction.
That is, in the application scenario, the first direction is a positive direction, that is, when the increment of the sensing value of the at least one gear/function sensing electrode 1200 is greater than the first threshold, a first identification instruction indicating that the magnetic control button 2000 is placed on the magnetic touch panel 1000 is generated; the second direction is a negative direction, that is, when the decrease amount of the sensing value of the at least one gear/function sensing electrode 1200 is greater than the first threshold, a second identification instruction indicating that the magnetic manipulation button 2000 is taken away from the magnetic touch panel 1000 is generated.
In this embodiment, with reference to fig. 4 and 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 are changed to be larger than a first threshold value in the first direction or the second direction; the first position/function sensing electrode 1210 is adjacent to the second position/function sensing electrode 1220, and when the magnetic attraction control button 2000 is placed on the magnetic attraction touch panel 1000, the projection of the position/function selection sensing block 2110 on the magnetic attraction touch panel 1000 at least partially overlaps the area between the first position/function sensing electrode 1210 and the second position/function sensing electrode 1220.
Specifically, when the magnetically attractive operation button 2000 is placed on the magnetically attractive touch panel 1000, the gear/function selection sensing block 2110 is simultaneously placed adjacent to two adjacent gear/function sensing electrodes 1200 with a high probability: in one case, the projection of the gear/function selection sensing block 2110 on the magnetic touch panel 1000 is entirely between the adjacent first gear/function sensing electrode 1210 and the second gear/function sensing electrode 1220, and in the second case, a part of the projection of the gear/function selection sensing block 2110 on the magnetic touch panel 1000 is between the adjacent first gear/function sensing electrode 1210 and the second gear/function sensing electrode 1220, and another part is overlapped on the first gear/function sensing electrode 1210 and/or the second gear/function sensing electrode 1220, at this time, when the magnetic control button 2000 is placed and the magnetic control button 2000 is taken away, the sensing values of the first gear/function sensing electrode 1210 and the second gear/function sensing electrode 1220 are changed by more than the first threshold value, so for the accuracy of identification at this time, the state of the magnetically attractive operation button 2000 needs to be determined according to the variation of the sensing values of the adjacent first gear/function sensing electrode 1210 and second gear/function sensing electrode 1220.
For example, in the application scenarios of fig. 4 and 5, the first position/function sensing electrode 1210 is closer to the position/function selection sensing block 2110 than the second position/function sensing electrode 1220, so that when the magnetically attracting control button 2000 is placed or taken away, the variation of the sensing value of the first position/function sensing electrode 1210 is greater than that of the second position/function sensing electrode 1220.
Meanwhile, in the application scenarios of fig. 4 and 5, when the magnetic attraction control button 2000 is placed or taken away, except for the first gear/function sensing electrode 1210 and the second gear/function sensing electrode 1220, the sensing values of the other gear/function sensing electrodes 1200 are not changed much in the first direction or the second direction, but do not exceed the first threshold.
In other embodiments, when it is ensured that the magnetic manipulation button 2000 is placed on the magnetic touch panel 1000, and the gear/function selection sensing block 2110 is directly opposite to one gear/function sensing electrode 1200, the step S110 may specifically be: the sensing values of the plurality of stage/function sensing electrodes 1200 are detected to determine whether there is a change in the sensing value of one stage/function sensing electrode 1200 in the first direction or the second direction, which is greater than the first threshold.
In the present embodiment, the first threshold exceeds 20% or more of the background noise.
Specifically, when the user operates the magnetic control knob 2000 to select a gear/function, the sensing value generated by the selected gear/function sensing electrode 1200 is changed, while the sensing value generated by the non-selected gear/function sensing electrode 1200 may also change, but does not vary by more than the amount of variation produced by the selected position/function sensing electrode 1200, that is, when the user selects a gear/function, the sensing electrode 1200 of the selected gear/function generates the largest variation, but there is an upper limit to the variation, wherein, the upper limit is defined as the noise floor, that is, when the user operates the magnetic control button 2000 to select the gear/function, the maximum variation amount of the sensing value generated by the selected gear/function sensing electrode 1200.
The reason why the variation of the sensing value of the at least one shift position/function sensing electrode 1200 in the first direction or the second direction is larger than the first threshold value in the present embodiment is to set the first threshold value to exceed 20% of the noise floor, for example, the first threshold value exceeds 20%, 30% or 40% of the noise floor, because the user operates the magnetic control button 2000 to select the shift position/function.
In this embodiment, the identification method further includes:
s130: the sensing value of the auxiliary function sensing electrode 1500 is detected to determine whether the sensing value is greater than the second threshold value in the first direction or the second direction.
S140: when it is determined that the sensing value of the auxiliary function sensing electrode 1500 changes in a first direction or a second direction and is greater than a second threshold value, a corresponding auxiliary recognition instruction is generated, where the auxiliary recognition instruction includes a first auxiliary recognition instruction indicating that the magnetic control button 2000 is placed on the magnetic touch panel 1000 and/or a second auxiliary recognition instruction indicating that the magnetic control button 2000 is taken away from the magnetic touch panel 1000.
In one embodiment, as shown in fig. 3, the magnetically operated knob 2000 further comprises an auxiliary key 2200 in addition to the gear/function selection sensing block 2110, and the magnetically operated knob 2000 further comprises: a conductive ring 2100, a first magnetic element 2300, a first insulating ring 2400, and a second insulating ring 2500.
In an application scenario, the position/function selection sensing block 2110 is protruded on an inner wall of the conductive ring 2100 and connected to the conductive ring 2100, the conductive ring 2100 is made of a conductive material, such as metal, and the position/function selection sensing block 2110 is integrally formed with the conductive ring 2100, the auxiliary key 2200 includes a cap 2210 and a rod portion 2220 protruded on the cap 2210, the cap 2210 is used for contacting with a hand of a user, the rod portion 2220 sequentially passes through the first insulating ring 2400, the conductive ring 2100 and the second insulating ring 2500 to contact with the touch substrate 1100, specifically, an end surface of the rod portion 2220 away from the cap 2210 is in contact with the touch substrate 1100, and the rod portion 2220 is a hollow structure having a groove (not shown) in which the first magnetic member 2300 is accommodated, and the first magnetic member 2300 and the second magnetic member (not shown) in the magnetically attracted touch panel 1000 attract each other to make the magnetically attracted control button 2000 to be attached to the touch substrate 1100, the first and second insulating rings 2400 and 2500 are used to isolate the conductive ring 2100 from the auxiliary key 2200.
The first magnetic member 2300 of the magnetically attractive operating button 2000 and the second magnetic member of the magnetically attractive touch panel 1000 may be a pair of magnets attracted to each other, or one of the magnets may be a magnet, and the other is a metal member capable of being attracted by the magnet.
Referring to fig. 2, corresponding to the auxiliary key 2200 in the magnetic control button 2000, an auxiliary function sensing electrode 1500 exists in the magnetic touch panel 1000, and the auxiliary function sensing electrode 1500 and the shift/function sensing electrode 1200 are located on the same side of the touch substrate 1100, and are configured to sense the operation on the auxiliary key 2200 in the magnetic control button 2000 to generate a corresponding sensing value.
In an application scenario, in the magnetic-attraction control knob 2000 of fig. 3, a user first changes the state of the gear/function selection sensing block 2110 by rotating the conductive ring 2100, so as to select a plurality of gear/function sensing electrodes 1200, and after the user selects a gear/function, the user also confirms by touching the auxiliary key 2200, and then the device adjusts the corresponding gear/function, that is, 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 generates a corresponding confirmation identification instruction.
In another application scenario, the user may also perform operations such as canceling, pausing, etc. by manipulating the auxiliary key 2200, for example, when the device is running, the user pauses the device by manipulating the auxiliary key 2200, or, after the user selects a gear or a function, the user cancels the previous selection of the gear or the function by manipulating the auxiliary key 2200.
In summary, the present application is not limited with respect to the functionality of the auxiliary key 2200.
For the auxiliary function sensing electrode 1500, when the magnetic manipulation button 2000 is placed or taken away, as shown in fig. 6 and 7, due to the capacitance sensing effect between the auxiliary function sensing electrode 1500 and the auxiliary key 2200, the variation of the sensing value on the auxiliary function sensing electrode 1500 is a fixed value, so that the present embodiment performs the auxiliary recognition by using the variation of the sensing value of the auxiliary function sensing electrode 1500, and can avoid that the variation of the sensing value of the at least one shift/function sensing electrode 1200 in the first direction or the second direction is larger than the first threshold value, not because the magnetic manipulation button 2000 is taken or placed but because of the interference of the external factors (for example, oil stain is generated on the magnetic manipulation button 2000), thereby ensuring the accuracy of the recognition.
In the present embodiment, when it is determined that the sensing value of the auxiliary function sensing electrode 1500 changes in the first direction to be greater than the second threshold value, a first auxiliary command is generated; alternatively, the second auxiliary command is generated when it is determined that the sensing value of the auxiliary function sensing electrode 1500 is changed in the second direction to be greater than the second threshold value.
The direction of the change of the induction value of the shift/function induction electrode 1200 is the same, and the direction of the change of the induction value of the auxiliary function induction electrode 1500 is opposite when the magnetic control button 2000 is placed and taken away.
In the present embodiment, the second threshold is equal to the first threshold. In other embodiments, the second threshold may not be equal to the first threshold, which is not limited herein.
It should be noted that, although the identification method of the present application is described above with reference to the structure of the magnetic attraction control button 2000 in fig. 3, the identification method of the present application can also be applied to magnetic attraction control buttons with other structures, that is, the present application does not limit the specific structure of the magnetic attraction control button.
