Detailed Description

Embodiments of the present utility model are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present utility model and should not be construed as limiting the utility model.

The following describes a base station and a sweeper of a host communication mode according to an embodiment of the present utility model with reference to the accompanying drawings.

Fig. 2 is a schematic structural diagram of a base station according to an embodiment of the present utility model, and referring to fig. 2, the base station 100 includes: a rectifying unit 110, a charging unit 120, a control unit 130, and a power supply unit 140.

Wherein, the input end of the rectifying unit 110 is connected with the alternating current power supply AC, and the rectifying unit 110 is configured to convert the alternating current provided by the alternating current power supply AC into a first direct current; an input end of the charging unit 120 is connected with an output end of the rectifying unit 110, an output end of the charging unit 120 is connected with the robot to be charged 200, and the charging unit 120 is configured to convert the first direct current into the second direct current so as to charge the robot to be charged 200; the control unit 130 is connected to the charging unit 120, and the control unit 130 is configured to control the charging unit 120 according to the charging requirement of the robot to be charged 200, so as to adjust the second direct current; an input terminal of the power supply unit 140 is connected to an input/output terminal of the rectifying unit 110, an output terminal of the power supply unit 140 is connected to the control unit 130, and the power supply unit 140 is configured to convert the alternating current/first direct current into a third direct current to supply power to the control unit 130.

Specifically, referring to fig. 2, the base station 100 includes two power loops, one being a main power loop from an alternating current power source AC to the robot to be charged 200 through the rectifying unit 110 and the charging unit 120, the main power loop mainly for supplying a second direct current to the robot to be charged 200 to charge the robot to be charged 200; the other is a sub power loop from the alternating current power AC to the control unit 130 through the input/output terminal of the rectifying unit 110 and the power supply unit 140, the sub power loop being mainly used to supply the third direct current to the control unit 130 to supply power to the control unit 130.

In the main power loop, the charging unit 120 may be a different type of power conversion circuit, for example, the charging unit 120 may be a full-bridge LLC circuit shown in fig. 3, the specific principle is not described herein, referring to fig. 3, the charging unit 120 may convert the first direct current U1 into the second direct current U2, and the control unit 130 may output PWM waves to the switching tubes Q1 to Q4 in the charging unit 120 to regulate the voltage and current of the second direct current, so that the control unit 130 may regulate the charging power provided to the robot 200 to be charged according to the charging requirement of the robot 200 to be charged; meanwhile, since the main power loop and the auxiliary power loop are independent of each other or only share the rectifying unit 110, the second direct current and the third direct current are not affected by each other, that is, the power supply sources of the robot to be charged 200 and the control unit 130 are independent of each other, and the charging power of the robot to be charged 200 is adjusted so as not to affect the power supply to the control unit 130, therefore, when the battery capacity of the robot to be charged 200 increases, the control unit 130 can adjust the voltage and the current of the second direct current according to the charging requirement of the robot to be charged 200, so as to meet the charging requirement of the robot to be charged. Therefore, compared with the related art, the base station 100 of the embodiment of the utility model can reduce one-stage power conversion, and can provide proper charging power for the charging robot 200 only through two-stage conversion of the ac/dc conversion of the rectifying unit 110 and the power conversion of the charging unit 120, thereby reducing the power loss during charging of the base station; in the secondary power loop, although the ac power needs to be subjected to ac-dc conversion and step-down processing to provide the control unit 130 with a fixed power supply voltage, no small power loss is generated, but since the power supply power required by the control unit 130 is small relative to the charging power required by the robot 200 to be charged, the power loss ratio generated is relatively low, so that the base station in the embodiment of the utility model can reduce the power loss during charging, so that the base station has higher charging efficiency, and the higher the charging power of the base station, the charging efficiency advantage of the base station in the embodiment of the utility model is more obvious.

Meanwhile, in the related art, as the charger and the battery are arranged on the robot, the robot is large in size, partial dead angles possibly exist and cannot enter when a house is cleaned, so that the cleaning capacity of the robot is reduced, and when the robot is charged, the charger and the battery generate heat, heat is accumulated on the robot, so that the safety of the robot is reduced.

In addition, in the related art, since the charger supplies power to the robot and other systems at the same time, when the charging voltage of the robot is too low, other systems may stop working due to the too low power supply voltage, and in the embodiment of the present utility model, since the power supply sources of the robot to be charged 200 and the control unit 130 are independent of each other, when the charging demand voltage of the robot to be charged 200 is too low, the power supply voltage of the control unit 130 is unchanged, and thus the working state can be maintained, and therefore, compared with the related art, the stability of the base station of the present utility model is higher.

According to the base station provided by the embodiment of the utility model, the charging unit is controlled by the control unit according to the charging requirement of the robot to be charged, so that the second direct current output by the charging unit and used for charging the robot to be charged is regulated; meanwhile, the alternating current/first direct current is converted into third direct current through the power supply unit, so that the control unit and a power supply circuit of the robot to be charged are mutually independent, so that the base station can adjust charging power according to the charging requirement of the robot to be charged, thereby reducing power loss during charging of the base station, improving charging efficiency of the base station, enhancing stability and safety during charging of the base station, reducing the volume of the robot to be charged, enhancing cleaning capability of the robot to be charged, and realizing integral optimization of the base station.

In some embodiments, referring to fig. 4, the base station 100 further comprises: the communication unit 150, the communication unit 150 is connected to the control unit 130, and the control unit 130 is further configured to communicate with the robot to be charged 200 through the communication unit 130 to obtain the charging requirement of the robot to be charged 200.

Specifically, referring to fig. 4, the robot to be charged 200 may include a processor 210, a battery 220, and a communication module 230, wherein the processor 210 is configured to sample an output voltage, an output current, and a battery temperature of the battery 220 and data, and communicate with the base station 100 through the communication module 230.

When the control unit 130 needs to obtain the charging requirement of the robot 200 to be charged, the control unit 130 can perform wireless communication with the processor 210 of the robot 200 to be charged through the communication unit 150 and the communication module 230, so as to obtain the output voltage, the output current, the battery temperature and other data of the battery 220 sampled by the processor 210, calculate the optimal output voltage and the output current reference (i.e. the charging requirement of the robot 200 to be charged) at this time, and recall the timing of the robot 200 to be charged, thereby better performing the battery charging strategy control.

As a specific example, when the robot to be charged 200 uses a lithium battery as a battery, the battery charging strategy of the control unit 130 may include:

s101, judging whether the robot works, if not, executing S102, and if so, executing S103;

s102, adopting a normal battery charging strategy to keep the battery capacity of the robot to be charged at 100%. For example, when the voltage across the single battery is less than 3V, the battery is awakened using a small current of 100MA, the voltage across the single battery is increased to 3V, the battery is charged at a charging speed of 0.5C until the battery charge reaches 80%, and then constant voltage charging of 4.15V is performed until the battery charge reaches 100%, and S106 is performed.

S103, judging the working mode of the robot, if the robot is in a sweeping mode, executing S104, and if the robot is in a mopping module (comprising mopping only and sweeping and mopping simultaneously), executing S105.

And S104, calculating the electric quantity required by the battery according to the sweeping area, when the electric quantity of the battery is insufficient to sweep the whole area and the electric quantity of the battery of the robot is reduced to 30%, recalling the robot, rapidly charging the battery for 6 minutes according to the charging speed of 1C, enabling the battery to charge 10% of the electric quantity, continuing to sweep the floor until the sweeping task is completed, and executing S106.

And S105, when the electric quantity of the battery is reduced to 60%, the robot is recalled, the battery is quickly charged for 6 minutes according to the charging speed of 1C, the mop is washed, the mopping task is continued until the mopping task is completed, and S106 is executed.

S106, ending.

Since the lithium battery can be rapidly charged within the power range of 25% -80%, in the related art, threshold charging control is generally adopted, for example, when the power of the battery is lower than 20%, the robot to be charged 200 is retracted for charging, which results in a charging process of sequentially performing low-current charging, rapid charging and constant-voltage charging when the battery 220 is charged, which prolongs the charging time, and when the user's house area is too large, no small power consumption is generated when the robot to be charged 200 is retracted, so that the battery 220 is charged close to full charge, and the service life of the battery is reduced. When the battery charging strategy is adopted, the electric quantity of the robot is ensured to be sufficient during sweeping and mopping, corresponding work can be completed, the robot can always perform a quick charging flow, the charging speed is improved, and meanwhile, full charge and discharge are avoided, so that the service life of the battery can be prolonged; meanwhile, the charging interval is reduced, so that the requirement on the battery capacity can be reduced, and the optimization of the battery charging strategy is realized.
