In the alternating magnetic field, the metal The foreign body will heat up quickly, causing a safety hazard.

Therefore, the working module 21 in the automatic lawn mower 20 can clean the foreign objects in the wireless charging station, which can effectively prevent the foreign objects in the wireless charging station, so as to ensure the wireless charging of the automatic lawn mower 20 at the wireless charging station. The environment is safe and reliable.

According to the foreign object cleaning method of the embodiment of the present application, the automatic lawn mower 20 can be wirelessly charged at the wireless charging station. When the automatic lawn mower 20 arrives at the wireless charging station, the automatic lawn mower 20 can charge the wireless charging station through its working module 21. The foreign objects are cleaned, thereby effectively preventing foreign objects from interfering with the wireless charging process, and improving the safety and reliability of the wireless charging process.

In some embodiments of the present application, the working module 21 includes: a cutting motor 211 to activate the working module 21 in the automatic lawn mower 20 to remove foreign objects in the wireless charging station. The method for removing foreign objects in the wireless charging station includes: starting The cutting motor 211 of the automatic lawn mower 20 uses the operation of the cutting motor 211 to remove foreign objects in the wireless charging station.

Further, using the operation of the cutting motor 211 to remove foreign objects in the wireless charging station includes: using the mechanical vibration generated by the cutting motor 211 to remove the foreign objects in the wireless charging station.

It is understandable that the automatic lawn mower 20 has a function of mowing grass, and the working module 21 is used to implement the mowing function of the automatic lawn mower 20, for example, when the working module 21 rotates, the grass can be cut. The working module 21 includes a cutting motor 211 and a cutting mechanism 212. The cutting motor 211 is used to drive the cutting mechanism 212 to rotate. When the cutting mechanism 212 rotates, the rapidly rotating cutting mechanism 212 can generate a turbulent airflow, which can affect the wireless charging station. The foreign objects are cleaned up.

When the cutting motor 211 drives the cutting mechanism 212 to rotate, the cutting motor 211 itself is also in operation. When the cutting motor 211 is running, it will generate vibration. The vibration can be transmitted to the wireless charging station contacted by the automatic lawn mower 20. Increase the difficulty of foreign matter attaching to the wireless charging station, so that the foreign matter can be separated from the surface of the wireless charging station.

At the same time, the rapidly rotating cutting mechanism 212 can generate a turbulent airflow, and under the action of the turbulent airflow, the difficulty of adhering foreign objects to the wireless charging station can be increased again to remove the foreign objects from the wireless charging station.

It is understandable that when the cutting motor 211 drives the cutting mechanism 212 to rotate, at least one of mechanical vibration and turbulent air flow can be generated. Foreign objects in the wireless charging station can be removed by mechanical vibration or turbulent air flow. When mechanical vibration is generated at the same time And when the air flow is disturbed, the effect of cleaning foreign objects is good.

It is understandable that when the automatic lawn mower 20 corresponds to the central area of the energy emission area, the wireless power exchange station has the best wireless charging effect on the automatic lawn mower 20. Thus, when the automatic lawn mower 20 corresponds to the central area of the energy emission area, the automatic lawn mower 20 stops walking, that is, maintains the state corresponding to the central area of the energy emission area, starts the working module 21, and controls the work module 21. The energy emission area is fully cleaned to remove foreign objects in the area and improve the reliability and safety of the wireless charging environment.

It should be noted that the "central area" refers to an area range in the energy emission area.

It is understandable that the timing of detecting the presence of foreign objects in the energy emission area can be set according to design requirements. For example, the detection time is set after the working module 21 is activated until the automatic lawn mower 20 and the energy emission area are not corresponding. When there is a foreign object, the automatic lawn mower 20 is stopped and wirelessly charged through the wireless charging station; the detection can also be set in the wireless charging station to wirelessly charge the automatic lawn mower 20, and the energy emission area is always The presence of foreign objects is detected to ensure the safety of the wireless charging process; it is also possible to detect whether there are foreign objects in the energy emission area before the automatic lawn mower 20 arrives at the wireless charging station to determine the reliability of the wireless charging environment in the energy emission area Sex.

Wherein, the method for detecting foreign objects may include: transmitting wireless energy through a wireless transmitting component (a component for transmitting wireless energy), and detecting the resonant frequency emitted by the wireless transmitting component, so as to detect whether there is a metal foreign object in the energy transmitting area.

Among them, the automatic lawn mower 20 can detect the electromagnetic field of the energy emission area in the wireless charging station, so as to detect the position of the automatic lawn mower 20. It should be noted that this detection method can also be applied to the automatic lawn mower 20 to detect whether it corresponds to the energy emission area.

Further, the automatic lawn mower 20 can detect the intensity of the electromagnetic field it receives. During the movement of the automatic lawn mower 20, when the electromagnetic field strength increases, the automatic lawn mower 20 gradually approaches the wireless charging station; when the electromagnetic field strength decreases At the time, the automatic lawn mower gradually moved away from the wireless charging station. Moreover, when the electromagnetic field intensity reaches a certain value, it can be determined that the automatic lawn mower 20 corresponds to the energy emission area.

Optionally, the position of the automatic lawn mower relative to the wireless charging station can also be determined by detecting the direction of the magnetic field of the electromagnetic field.

Of course, the detection method of the charging station detection module is not limited to this, and the position information of the automatic lawn mower 20 can be collected through a distance sensor.
