In order to solve the problems in the prior art, the invention provides a portable equipment control system based on lifting and lowering, which uses a lifting and lowering module to directly drive a motor, and omits a motor driving module. If the battery voltage is high but the required gear voltage is relatively low, starting a step-down mode to step down to the required voltage; if the battery voltage is low but the required gear voltage is relatively high, the boost mode is turned on to boost to the required voltage.

Referring to fig. 1, a schematic diagram of a buck-boost control system of a portable device according to an embodiment of the invention is shown. The lifting pressure control system of the present embodiment includes: step-up and step-down module 101, voltage adjustment module 102, control module 103, battery module 104, and drive module 105; wherein the control module 103 controls and connects with the voltage regulating module 102.

In this embodiment, when the control module 103 monitors that the current voltage of the battery module 104 is greater than a preset voltage value, the voltage adjustment module 102 is controlled to adjust the voltage gear to the preset voltage value, so that the output voltage of the buck-boost module 101 is stabilized at the preset voltage value and then is output to the driving module 105.

As shown in fig. 2, a schematic diagram of a buck-boost module according to an embodiment of the invention is shown. The buck-boost module comprises a buck-boost chip U4, such as a TPS63030 chip special for portable electronic products or any chip element capable of realizing the buck-boost function in the prior art.

The buck-boost chip comprises an enabling pin, and the enabling pin is connected with the control module; when the driving module does not work, the control module controls the enabling pin to be at a low level so as to close the buck-boost chip. Specifically,

pins

12 and 13 of the buck-boost chip U4 are enable pins, the enable pins are connected to the control module through a CR_OUT line, and when the motor does not work, the control module is connected with the buck-boost enable pins of the buck-boost chip U4 through the CR_OUT line to control the buck-boost enable pins to be at a low level, so that the buck-boost module is closed, the standby current loss is reduced, the standby time and the service time are prolonged, and the purposes of energy conservation and environmental protection are achieved.

In some examples, a voltage adjustment pin (pin No. 3) of the buck-boost chip U4 is connected to a resistor R4 for collecting feedback current output voltage. The voltage regulation pin is also connected to the voltage regulation module through a C_V line so as to realize voltage output of different gears.

Specifically, the buck-boost chip U4 determines according to the current voltage and the preset voltage value of the battery module, and starts the buck-boost function. When the current voltage of the battery module is larger than the preset voltage value, starting a step-down function, stabilizing the output voltage at the preset voltage value, and then driving the driving module to ensure that the water pressure of the gear is constant; when the current voltage of the battery module is smaller than the preset voltage value, starting a boosting function, stabilizing the output voltage at the preset voltage value, and then driving the driving module to ensure that the water pressure of the gear is constant.

The boost-buck module is a high-efficiency boost circuit, and has the advantages of large output current, high efficiency and small volume. Therefore, the heating is also small, and the device is suitable for the handheld device with large current and small volume. It should be noted that, under the factors of different materials, structures, capacities, manufacturers, models, use environments, discharge rates and the like, the discharge curves of the batteries are different. For example, after a new battery is charged and left to stand for 12 hours, is discharged, the voltage is higher than the rated voltage when the capacity is more than 90%, the voltage is close to the rated voltage when the capacity is higher than 5%, and the voltage drops sharply when the capacity is lower than 5%.

As shown in fig. 3, a schematic structure of a voltage regulation module according to an embodiment of the invention is shown. The voltage regulating module comprises a selection switch chip U5; the pin 3 of the switch selection chip U5 is connected to the buck-boost module through a connecting wire C_V, the pin 4 is connected to the control module through a connecting wire CR1, and the pin 8 is connected to the control module through a connecting wire CR2, and is used for switching between different gear voltages.

The requirements of different gears on voltage are different, small gears use small voltage, and large gears use large voltage to drive the motor. The voltage regulating module is connected to the control module, and switches to resistors with different resistance values according to the setting of the control module, wherein the resistors are connected to a feedback system with stable voltage of the voltage boosting and reducing module so as to realize different gear voltages, and the gear voltages are not changed along with the attenuation of the battery voltage. Specifically, the switch selection chip U5 is externally connected with resistors with different resistance values respectively; and the control module sends a selection instruction to the selection switch chip, and then selects a resistor with a corresponding resistance value to be connected with the buck-boost module, so that the buck-boost module outputs voltage of a corresponding gear.

In some examples, the plurality of pins of the switch selection chip U5 are respectively connected with resistors with different resistance values; after each resistor is connected with the step-up and step-down module, the step-up and step-down module outputs voltage of corresponding gear. And a No. 5 pin connecting resistor R20, a No. 7 pin connecting resistor R21 and a No. 10 pin connecting resistor R22 of the switch chip U5 are selected, and the resistors R20, R21 and R22 are connected into voltage regulation of the buck-boost module, so that stability of different voltages is realized. The adjustment modes of the gear voltages are as follows:

first gear voltage: the control module sets CR1 to high level and CR2 to high level, and c_v is connected to the resistor R22 through the selection switch chip U5. The resistor R4 connected with the pin 4 of the buck-boost chip U4 is connected to the pin 3 rear connection resistor R22 of the selection switch chip U5 through a connecting wire C_V; the resistance of the resistor R22 is set to be 250KΩ, the output voltage of the common feedback voltage-boosting module of the resistor R4 and the resistor R22 is 2.5V, and the voltage at two ends of the motor is 2.5V. The analysis is as follows in connection with fig. 2 and 3: the voltage of the voltage regulating pin (pin No. 3) of the buck-boost chip U4 is 0.5V, so vm=0.5V (r4+r22)/r22=2.5V. Therefore, when the battery voltage is lower than 2.5V, the voltage boosting function is automatically started by the voltage boosting module, when the battery voltage is higher than 2.5V, the voltage at two ends of the motor is always kept at 2.5V, and the purpose of constant voltage control is achieved without being influenced by the change of the battery electric quantity.

Second gear voltage: the control module sets CR1 to high level and CR2 to low level, and c_v is connected to the resistor R21 through the selection switch chip U5. The resistor R4 connected with the pin 4 of the buck-boost chip U4 is connected to the pin 3 rear connection resistor R21 of the selection switch chip U5 through a connecting wire C_V; the resistance value of the resistor R21 is set to be 200KΩ, the output voltage of the common feedback voltage-boosting module of the resistors R4 and R22 is 3V, and the voltage at two ends of the motor is 3V. The analysis is as follows in connection with fig. 2 and 3: the voltage of the voltage regulating pin (pin No. 3) of the buck-boost chip U4 is 0.5V, so vm=0.5V (r4+r21)/r21=3v. Therefore, when the battery voltage is lower than 3V, the voltage boosting module automatically starts the voltage boosting function, when the battery voltage is higher than 3V, the voltage at two ends of the motor is always kept at 3V, and the purpose of constant voltage control is achieved without being influenced by the change of the electric quantity of the battery.

Third gear voltage: the control module sets CR1 to be low level, CR2 to be low level, and C_V is connected to a resistor R20 through a selection switch chip U5; the resistance of the resistor R20 is set to be 150KΩ, the output voltage of the common feedback voltage-boosting module of the resistors R4 and R20 is 3.83V, and the voltage at two ends of the motor is 3.83V. The analysis is as follows in connection with fig. 2 and 3: the voltage of the voltage regulating pin (pin No. 3) of the buck-boost chip U4 is 0.5V, so vm=0.5V (r4+r20)/r20=3.83V. Therefore, when the battery voltage is lower than 3.83V, the voltage boosting function is automatically started by the voltage boosting module, when the battery voltage is higher than 3.83V, the voltage at two ends of the motor is always kept at 3.83V, and the purpose of constant voltage control is achieved without being influenced by the change of the battery electric quantity.

It should be noted that, the present invention is not limited to the above embodiments, and the number of the selection switch chips is not limited, and the number of resistors connected to each selection switch chip is not limited, that is, the step-up/step-down module may extend the adjustment gear by adding the number of the selection switch chips and/or the number of resistors externally connected to each selection switch chip.

In some examples, the switch selection chip U5 is connected to an adjustable resistor (not shown); and the adjustable resistor is connected with the buck-boost module and is controlled to adjust the resistance value, and the buck-boost module outputs the voltage of the corresponding gear. For example, when the resistance of the adjustable resistor is adjusted to be 250KΩ, the output voltage of the buck-boost module can be 2.5V; the resistance of the adjustable resistor is adjusted to 200kΩ, so that the output voltage of the buck-boost module can be output to 3V, and the principle is similar to the above, and the description is omitted here.

In some examples, the buck-boost control system of the portable device further includes a key module. The key module 106 is connected with the control module 103; the key module 106 responds to the user operation and sends a corresponding operation instruction to the control module so as to perform gear adjustment, output control or wake-up operation on the portable device. For easy understanding, referring to fig. 4, a schematic circuit structure of a KEY module according to an embodiment of the present invention is shown, in which S1 and S2 are KEYs and connected to a control module through KEY1 and KEY2 lines.

In some examples, the buck-boost control system further includes a display module 107 coupled to the control module 103 for displaying the status of the portable device. For example, the current operating state of the portable device, such as a charging state, a sleep state, a normal operating state, an electric quantity state, a gear adjusting state, etc., can be displayed by different flicker frequencies, different display colors, or different combinations of flicker rates and display colors; the electric quantity state mainly refers to the state of sufficient, medium or lack of the current electric quantity of the equipment. For ease of understanding, a schematic structural diagram of a display module according to an embodiment of the present invention will be shown in conjunction with fig. 5, where the display module includes 3 groups of LED indication units, each group of LED indication units is composed of a resistor and an LED lamp, R1, R2, R3 are resistors, D1, D2, D3 are LED indication lamps, and are connected to a control module through LED1, LED2, and LED3 wires.

In some examples, the buck-boost control system further includes a voltage regulator module 108; the voltage stabilizing module 108 is connected to the battery module and the control module, and is configured to convert the fluctuating voltage output by the battery module into a stable voltage and provide the stable voltage to the control module. The portable device (such as a tooth cleaner) usually generates very large current when working, and the current is output in a pulse form, so that the voltage of the battery module is always in a fluctuation state, and if the ripple wave of the battery module is directly output to the control module, the control module is unstable. The voltage stabilizing module in this embodiment is used to convert the fluctuating voltage into a stable voltage, so as to provide a stable working voltage for the control unit. For ease of understanding, a schematic structural diagram of a voltage regulator module according to an embodiment of the present invention is now shown in conjunction with fig. 6, where the voltage regulator module includes: the voltage stabilizing chip U1 (such as an LM7805 chip, an LM1117 chip, an LM2576 chip and the like) is used for providing a stable power supply for the control module, C1, C4 and C5 are capacitors, and D8 is a diode.

In addition, the charging module 109 is further configured to monitor a charging state by the control module.

The circuit structure of the charging module is shown in fig. 7, and comprises a charging management chip U3, and a pin 2 of the charging management chip is connected with a resistor R15 for setting the charging current; the pin 8 is connected to the control module through divider resistors R17 and R18 and a connecting line Char_full, so that whether the battery module is fully charged or not is monitored; the No. 4 pin leads out resistors R14 and R16 and is connected to the control module through a Charge line for rapidly detecting whether the charging is in progress; and the No. 5 pin leads out resistors R5 and R6, and is connected to the control module through an AVCD line for monitoring the electric quantity of the battery in real time. The diode D6 is a protection diode for eliminating external electrostatic interference and can limit the external input power supply not to be higher than 5.5V. The diode D7 is a diode for switching power supply, and when the battery is charged, the external power supply is switched to supply power for the micro-control unit module, so that the charging speed is improved, and the battery can be prevented from supplying power to the outside when the battery is fully charged, and the electric quantity is reduced.

The lifting pressure control method of the embodiment is applied to the control module in the lifting pressure control system of the portable equipment; the step-up/step-down control method includes steps S81 and S82.

Step S81: when the current voltage of the battery module is monitored to be larger than a preset voltage value, the voltage adjusting module is controlled to downwards adjust the voltage gear to the preset voltage value, so that the output voltage of the voltage increasing and decreasing module connected with the voltage adjusting module is stabilized at the preset voltage value and then is output to the driving module.
