A motor control system provided in an exemplary embodiment of the present application is described next. Referring specifically to fig. 1, a schematic structural diagram of a motor control system according to an exemplary embodiment of the present application is shown. As shown in fig. 1, the motor control system includes: the device comprises a pressure detection module 110, a control module 120, a power module 130, a switching tube driving module 140, a switching tube module 150 and a motor 160. Wherein:

the pressure detection module 110 is configured to detect a pressure value received by the target position. The motor control system may be, but is not limited to being, applied to an electric toothbrush, and the target location may be, but is not limited to, a location of a brush head of the electric toothbrush. The pressure detection module 110 may be disposed on the head of the electric toothbrush, and/or inside the handle, and/or on the drive shaft of the electric toothbrush, as embodiments of the present application are not limited in this regard.

The control module 120 is respectively connected to the pressure detection module 110, the power module 130, and the switching tube driving module 140, and is configured to receive a start command, and in response to the start command, control the switching tube driving module 140 to generate a first pulse width modulation signal, and control the power module 130 to output a first driving voltage. Meanwhile, the control module 120 may further obtain a pressure value detected by the pressure detection module 110, and control the switching tube driving module 140 to generate a corresponding pulse width modulation signal (PWM signal) according to the pressure value, and control the power module 130 to output a corresponding driving voltage. For example, but not limited to, when the pressure value is greater than the first preset threshold, the control module 120 may control the switching tube driving module 140 to generate the second pwm signal, and control the power module 130 to output the second driving voltage.

The switching tube driving module 140 is connected to the switching tube module 150, and is configured to transmit a pulse width modulation signal (PWM signal) to the switching tube module 150.

It is to be understood that the switching tube driving module 140 may include a plurality of driving modules, such as a first driving module and a second driving module, and the plurality of driving modules may respectively provide different pulse width modulation signals (PWM signals) for the motor 160, for example, but not limited to, the first driving module provides a first pulse width modulation signal for the motor 160, the second driving module provides a second pulse width modulation signal for the motor 160, and the embodiment of the present application is not limited thereto.

The power module 130 is connected to the motor 160 for supplying a driving voltage to the motor 160.

It is to be understood that the power module 130 may include a plurality of power modules, such as a first power module and a second power module, and the plurality of power modules may respectively provide different driving voltages for the motor 160, for example, but not limited to, the first power module provides the first driving voltage for the motor 160, the second power module provides the second driving voltage for the motor 160, and the embodiment of the present application is not limited thereto.

The switching tube module 880 is configured to control the motor 860 to enter a corresponding operation mode based on the driving voltage according to the pulse width modulation signal (PWM signal).

The motor 860 is configured to enter a corresponding operation mode according to a driving parameter of a pulse width modulation signal (PWM signal) transmitted by the switching tube module 150 based on a driving voltage provided by the power module 130. For example, but not limited to, based on the first driving voltage provided by the power module 130, entering the micro-vibration mode according to the driving parameter of the first pwm signal transmitted by the switching tube module 150; based on the second driving voltage provided by the power module 130, the driving parameter of the second pwm signal transmitted by the switching tube module 150 enters a normal mode, and so on. The driving parameter of the first pulse width modulation signal is smaller than the driving parameter of the second pulse width modulation signal, and the first driving voltage is smaller than the second driving voltage. The vibration parameters of the motor 860 in the micro-vibration mode are smaller than those in the normal mode.

The motor control system is applied to an electric toothbrush, and the motor 860 is used for driving the brush head of the electric toothbrush to vibrate according to vibration parameters corresponding to the operation mode.

Next, in connection with fig. 1, a motor control method according to an exemplary embodiment of the present application will be described by taking an example in which the motor control method is applied to an electric toothbrush. Referring specifically to fig. 2, a schematic flow chart of a motor control method according to an embodiment of the present application is shown. As shown in fig. 2, the motor control method includes the steps of:

step 201, a start command is received, a first pulse width modulation signal is generated in response to the start command, the power supply module is controlled to output a first driving voltage, and a pressure value received by the target position is detected by the pressure detection module.

Step 202, transmitting a first pwm signal to the switching tube module, and transmitting a first driving voltage to the motor through the power module, so that the switching tube module controls the motor to enter a micro-vibration mode based on the first driving voltage according to the first pwm signal.

Specifically, the activation command may be from a switch button of the electric toothbrush. When the user presses the switch key, a start instruction is transmitted to the control module. The control module can receive a starting instruction triggered by a user, responds to the starting instruction to control the switching tube driving module to transmit a first pulse width modulation signal to the switching tube module, and controls the power supply module to output a first driving voltage to the motor, so that the motor is controlled to enter a micro-vibration mode, namely, the electric toothbrush directly enters the micro-vibration mode after being started, the brush head of the electric toothbrush slightly vibrates in the micro-vibration mode, and the vibration duty ratio, the vibration frequency and the vibration amplitude of the brush head are very small, so that the user is reminded of successful starting of the electric toothbrush through small vibration and the consumption of electric energy is saved, the situation that the electric toothbrush is started to cause the splash of toothpaste when the user smears the toothpaste is prevented, and the user experience is improved. Meanwhile, after receiving the starting instruction, the control module can also control the pressure detection module to detect the pressure value received by the target position of the electric toothbrush in response to the starting instruction. The pressure detection module may be disposed on the head of the electric toothbrush, and/or inside the handle, and/or on the drive shaft of the electric toothbrush, as embodiments of the present application are not limited in this respect.

Further, in order to prevent the problem that the brush head and teeth are not attached to cause the toothpaste to splash, the pressure value received by the target position is related to the pressure value received by the brush head of the electric toothbrush, so that whether the brush head is attached to the teeth or not is known according to the pressure value received by the brush head, and the power supply module is controlled to output the driving voltage according to the pressure value received by the brush head of the electric toothbrush and the switching tube driving module generates the first pulse width modulation signal.

And 203, in the micro-vibration mode, determining the working mode of the motor in response to a preset condition.

Specifically, the preset condition has a corresponding relation with the working mode of the motor. The above-described operation modes may include, but are not limited to, a cleaning mode, a sensing mode, a whitening mode, a nursing mode, a polishing mode, and the like. The preset condition may be, but is not limited to, an operation mode adjustment command triggered by a corresponding operation mode of the electric toothbrush selected by the user.

In the micro-vibration mode, for example, after the user presses the button corresponding to the cleaning mode, a cleaning command is transmitted to the control module. After receiving the cleaning command, the control module determines that the working mode of the motor is a cleaning mode in response to the cleaning command, namely, in a micro-vibration mode, the control module controls the motor to drive the brush head of the electric toothbrush to vibrate according to the corresponding vibration frequency, vibration amplitude and vibration duty ratio based on the first driving voltage corresponding to the cleaning mode and the first pulse width modulation signal corresponding to the cleaning mode.

Optionally, in the micro vibration mode, the first pulse width modulation signals corresponding to the different working modes can be different, and the first driving voltages corresponding to the different working modes can be different, namely, in the micro vibration mode, aiming at the difference of the working modes of the motor, the motor can be controlled to work with pertinence by adopting corresponding working parameters (the first pulse width modulation signals and the first driving voltages), so that a user is informed of the micro vibration mode of the electric toothbrush in which working mode is currently located, the user can intuitively feel the difference of the motor in different working modes in the micro vibration module, and the user can intuitively know the current working mode of the electric toothbrush and whether the electric toothbrush is regulated to the self-wanted working mode or not conveniently.

Optionally, in the micro-vibration mode, the first pulse width modulation signals corresponding to the different working modes may be the same, and the first driving voltages corresponding to the different working modes may be the same, that is, in the micro-vibration mode, no matter what working mode the motor is in, the motor may work by adopting the same working parameters (the first pulse width modulation signal and the first driving voltage), so that the user is intuitively informed that the electric toothbrush is in the micro-vibration mode, the user can put on the brush head to apply toothpaste, and the use experience of the user is improved.

Step 204, determining whether the pressure value is greater than a first preset threshold.

Specifically, after the pressure value to which the target position is subjected is detected by the pressure detection module, it may also be determined whether the pressure value is greater than a first preset threshold. The first preset threshold may be, but is not limited to, 0.2N, 0.1N, etc.

And step 205, generating a second pulse width modulation signal according to the working mode determined in the micro-vibration mode under the condition that the pressure value is larger than a first preset threshold value, and controlling the power supply module to output a second driving voltage.

Step 206, transmitting the second pwm signal to the switching tube module, and transmitting the second driving voltage to the motor through the power module, so that the switching tube module controls the motor to enter the normal mode based on the second driving voltage according to the second pwm signal.

Specifically, if the pressure value received by the target position is detected to be greater than the first preset threshold value, it can be considered that the brush head is attached to the teeth, and the user wants to clean the teeth attached to the brush head, then the switch tube driving module can be controlled to transmit a corresponding second pulse width modulation signal to the switch tube module according to the determined working mode in the micro-vibration mode, and the power supply module is controlled to output a corresponding second driving voltage to the motor, so that the switch tube module can control the motor to enter a normal mode based on the second driving voltage according to the second pulse width modulation signal, namely, the electric toothbrush is controlled to enter the normal mode corresponding to the working mode. The driving parameters of the first pulse width modulation signal are smaller than those of the second pulse width modulation signal, and the first driving voltage is smaller than the second driving voltage, so that the vibration parameters of the motor in the micro vibration mode are smaller than those of the motor in the normal mode, the vibration amplitude, the vibration frequency and the like of the brush head in the micro vibration mode are smaller than those in the normal mode, a user can know that the electric toothbrush is normally started through slight vibration, and the problem that toothpaste splashes due to overlarge vibration amplitude and/or vibration frequency of the brush head when the brush head is not attached to teeth can be prevented.

The first driving voltage may be, but is not limited to, half the second driving voltage.

Further, the driving parameters include duty ratio and/or frequency, and the switching tube module can control the motor to vibrate at the corresponding duty ratio and/or frequency based on the driving voltage according to the pulse width modulation signal.

In step 207, the motor is controlled to maintain the micro-vibration mode when the pressure value is less than or equal to the first preset threshold value.

Specifically, after the switch tube module responds to the starting instruction to enable the motor to be controlled to enter the micro-vibration mode based on the first driving voltage according to the first pulse width modulation signal, if the pressure value received by the target position is detected to be smaller than or equal to a first preset threshold value, the brush head can be considered to be not attached to the teeth, the motor can be continuously controlled to maintain the micro-vibration mode with smaller vibration parameters, the problem that toothpaste splashes when the brush head is not attached to the teeth can be further prevented, and the loss of electric energy when the brush head is not attached to the teeth can be further saved.

Referring next to fig. 3, a flowchart of another motor control method according to an embodiment of the present application is shown. As shown in fig. 3, the motor control method includes the steps of:

step 301, receiving a start command, generating a first pulse width modulation signal in response to the start command, controlling the power module to output a first driving voltage, and detecting a pressure value received by the target position through the pressure detection module.

Specifically, step 301 corresponds to step 201, and will not be described here.

Step 302, a first pwm signal is transmitted to the switching tube module, and a first driving voltage is transmitted to the motor through the power module, so that the switching tube module controls the motor to enter a micro-vibration mode based on the first driving voltage according to the first pwm signal.

Specifically, step 302 corresponds to step 202, and will not be described in detail herein.

Step 303, in the micro-vibration mode, determining the working mode of the motor in response to a preset condition.

Specifically, step 303 corresponds to step 203, and will not be described herein.

Step 304, it is determined whether the pressure value is greater than a first preset threshold.

Specifically, step 304 corresponds to step 204, and will not be described here.

And 305, generating a second pulse width modulation signal according to the determined working mode in the micro-vibration mode under the condition that the pressure value is larger than a first preset threshold value, and controlling the power supply module to output a second driving voltage.

Specifically, step 305 corresponds to step 205, and will not be described herein.

Step 306, transmitting the second pwm signal to the switching tube module, and transmitting the second driving voltage to the motor through the power module, so that the switching tube module controls the motor to enter the normal mode based on the second driving voltage according to the second pwm signal.

Specifically, step 306 corresponds to step 206, and will not be described here.

Step 307, controlling the motor to maintain the micro-vibration mode under the condition that the pressure value is less than or equal to the first preset threshold value.

Specifically, step 307 corresponds to step 207, and will not be described in detail herein.

In step 308, the pressure value received by the target location is detected by the pressure detection module.

Specifically, after the motor enters the normal brushing mode, i.e., the normal mode, from the micro-vibration mode, the pressure detection module can also continue to detect the pressure value received by the target position of the electric toothbrush.

Step 309, determining whether the pressure value is less than a second preset threshold.

In step 310, if the pressure value is smaller than the second preset threshold, a first pwm signal is generated, and the power module is controlled to output a first driving voltage.

Step 311, if the pressure value is greater than or equal to the second preset threshold value, the motor is controlled to maintain the normal mode.

Specifically, after the motor enters the normal brushing mode from the micro-vibration mode, if the pressure value received by the target position is detected to be smaller than the second preset threshold value, it can be considered that the user switches brushing areas in the brushing process, in order to avoid uncomfortable feeling in oral cavity areas such as gums of the user in the process of switching brushing areas due to larger vibration frequency, vibration amplitude and the like of the brush head in the normal mode, the switch tube driving module can be controlled to generate a first pulse width modulation signal, the power supply module is controlled to output a first driving voltage, and after the first pulse width modulation signal is generated and the power supply module is controlled to output the first driving voltage, namely, step 310 is executed again, so that the motor is controlled to switch from the normal mode to the micro-vibration mode with smaller vibration frequency and/or smaller vibration amplitude in the middle of switching brushing areas, and brushing experience of the user is further improved.

Further, in order to prevent the user experience from being affected by frequent switching to the micro-vibration mode during the normal brushing process of the user, the second preset threshold is smaller than or equal to the first preset threshold, that is, after entering the normal brushing mode, the motor is controlled to switch from the normal mode to the micro-vibration mode with smaller vibration frequency and/or smaller vibration amplitude only when detecting that the pressure value is smaller than the second preset threshold, that is, when detecting that the user switches the brushing area during the brushing process; if the detected pressure value is greater than or equal to the second preset threshold value, the user can be considered to be in the normal tooth brushing process, and the motor can be controlled to continuously maintain the normal mode, so that the electric toothbrush can continuously complete the tooth cleaning work in the normal mode.

For example, if the first preset threshold is 5N and the second preset threshold is 3N, in order to prevent the problem that the brush head vibrates to cause the splash of the toothpaste when the electric toothbrush is started in the process that the toothpaste is applied or the toothpaste is applied but the brush head is not attached to the teeth, after a starting instruction is received, i.e. the electric toothbrush is just started, the motor can be controlled to drive the brush head to enter a micro vibration mode with smaller vibration frequency and/or vibration amplitude; after the electric toothbrush is started and the motor enters the micro-vibration mode, the motor is controlled to switch from the micro-vibration mode to the normal mode only when the pressure value received by the target position (such as but not limited to a brush head and the like) of the electric toothbrush is detected to be larger than a first preset threshold value of 5N, and the brush head is considered to be attached to teeth; in the normal brushing process of the user, if the pressure value received by the target position (such as but not limited to a brush head and the like) of the electric toothbrush is detected to be smaller than the second preset threshold value 3N, the user can be considered to switch the brushing area in the normal brushing process, and the motor can be controlled to return to the micro-vibration mode in the middle of switching the brushing area, so that the uncomfortable feeling of the oral cavity area such as the gum and the like of the user caused by the larger vibration frequency, the larger vibration amplitude and the like in the normal mode is avoided, and the brushing experience of the user is improved; if the pressure value received by the target position (such as but not limited to the brush head and the like) of the electric toothbrush is detected to be greater than or equal to the second preset threshold value 3N in the normal tooth brushing process of the user, the brush head and the teeth can be considered to be in a joint state all the time, the motor can be controlled to continuously maintain the normal mode, and accordingly the electric toothbrush can be ensured to continuously complete tooth cleaning work in the normal mode.

Referring next to fig. 4, a flowchart of another motor control method according to an embodiment of the present application is shown. As shown in fig. 4, the motor control method includes the steps of:

step 401, receiving a start command, generating a first pulse width modulation signal in response to the start command, controlling the power module to output a first driving voltage, and detecting a pressure value received by the target position through the pressure detection module.

Specifically, step 401 corresponds to step 201, and will not be described here.

Step 402, transmitting a first pwm signal to the switching tube module, and transmitting a first driving voltage to the motor through the power module, so that the switching tube module controls the motor to enter the micro-vibration mode based on the first driving voltage according to the first pwm signal.

Specifically, step 402 corresponds to step 202, and will not be described in detail herein.
