Referring to fig. 3, fig. 3 is a flowchart illustrating a foreign object removing method of a wireless charging device according to a first embodiment of the present invention. In this embodiment, the method comprises:
step S10, after the wireless charging device is powered on, the deflector rod is controlled to perform uniform reciprocating motion on the coil protection shell of the wireless charging device;
after the wireless charging device is powered on, the controller controls the shifting rod to perform uniform reciprocating motion on the coil protection shell of the wireless charging device, namely, the servo motor is controlled to perform uniform motion, the output of the servo motor drives the link rod to rotate, and the rotation of the link rod can drive the shifting rod to move. After the wireless equipment is powered on, if no foreign matter exists on the coil protection shell of the wireless charging equipment, the deflector rod does uniform reciprocating motion on the coil protection shell of the wireless charging equipment; after the wireless charging equipment is powered on, if foreign matters exist on the coil protection shell of the wireless charging equipment, the shifting rod does not do uniform reciprocating motion on the coil protection shell of the wireless charging equipment.
Step S20, judging whether foreign matter exists on the coil protection shell of the wireless charging equipment according to the torque value detected in real time; if yes, go to step S30;
moment is physically the tendency of a force to cause an object to rotate about a rotational axis or pivot. The unit of moment is newton-meters. The turning moment is also called torque or torque. The moment can cause the object to change its rotational movement. Pushing or pulling involves force, while twisting involves torque.
The foreign matter in this embodiment may be a metal substance, and may be a metal foreign matter such as an iron sheet, a pop can, a coin, or the like, which falls or adheres to a coil protection housing outside a transmitting coil and a receiving coil of the wireless charging device due to environmental exposure. Since an alternating magnetic field exists between the transmitting coil and the receiving coil during the charging process, the metal foreign matters can form induced current and induced electromotive force. Along with the progress of charging process, metal foreign matter temperature constantly rises, when the temperature surpassed certain limit, arouses danger such as conflagration easily, has the potential safety hazard. The embodiment can determine whether foreign matters exist or not by the uniform reciprocating motion of the deflector rod on the coil protection shell of the wireless charging equipment. The servo motor does uniform motion, the output torque of the servo motor is a fixed value, the servo motor drives the shifting lever to move, and the shifting lever also does uniform reciprocating motion, so that the moment value of the shifting lever is also a fixed moment value; if not, the poking rod touches the foreign matter when reciprocating on the coil protection shell of the wireless charging equipment, and the foreign matter exists on the coil protection shell. It can be understood that when foreign matters exist on the coil protection shell, the torque value measured in real time is generally larger than that of the shifting lever in uniform reciprocating motion due to the blocking of the foreign matters.
And step S30, increasing the torque to control the poking rod to remove foreign matters on the coil protection shell of the wireless charging device through the increased torque.
When there is the foreign matter on wireless battery charging outfit's the coil protection casing in this embodiment, need increase motor output torque, driving lever moment value also corresponding increase simultaneously for can push out wireless battery charging outfit through the driving lever behind the increase effort foreign matter on with wireless battery charging outfit's the coil protection casing outside. Wherein the increased torque is greater than the torque measured due to the presence of a foreign object. Further, if it is determined that no foreign object is present on the coil protection housing of the wireless charging device according to the torque value detected in real time, the next determination of whether a foreign object is present is performed, that is, the step S20 is returned to be continuously executed, and the fact that whether a foreign object is present on the housing is detected in real time by returning the continuous detection torque when no foreign object is present can be ensured, so that the influence on the wireless charging caused by the generation of the foreign object is timely reduced or even eliminated.
This embodiment all can the real-time detection before wireless charging on the coil protection casing of wireless battery charging outfit whether there is the foreign matter in the wireless charging process or the coil protection casing, when there is the foreign matter on the coil protection casing of wireless battery charging outfit, the foreign matter on the coil protection casing of wireless battery charging outfit is clear away to the accessible driving lever, it needs artifical manual clear away to have removed from, can clear away the foreign matter that exists on the coil protection casing of wireless battery charging outfit automatically, the cost of labor has been practiced thrift, guarantee wireless charging process safety and go on simultaneously.
Further, in other embodiments, the step S30 may be preceded by the following steps:
detecting whether an electric automobile exists in a preset range of the wireless charging equipment;
and when the electric vehicle exists in the preset range of the wireless charging equipment, sending charging equipment abnormity reminding information to the electric vehicle, and executing the step S30.
When there is the foreign matter on wireless battery charging outfit's the coil protection casing, if charge this moment, there is the potential safety hazard, so can not carry out wireless charging, the controller can be through wireless battery charging outfit or set up the sensor by device self, whether to detect wireless battery charging outfit certain limit has electric automobile, if there is electric automobile then the unusual reminder information of initiative sending battery charging outfit gives electric automobile, make electric automobile driver can know wireless battery charging outfit's the condition after receiving unusual suggestion through electric automobile, do not use this unusual wireless battery charging outfit to charge. It will be appreciated that the torque can be increased directly when there is no electric vehicle around the device. Whether electric vehicles exist around the wireless charging equipment or not is judged, prompt information is sent, a driver can be helped to know the abnormal wireless charging equipment, and the waste of vehicle charging matching time is avoided.
Further, in the second embodiment, the step S20 includes:
step S21, judging whether the moment value detected in real time is a first preset moment value corresponding to the uniform reciprocating motion; if the detected torque value is a first preset torque value corresponding to the uniform reciprocating motion, no foreign matter exists on a coil protection shell of the wireless charging equipment; and if the detected torque value is not the first preset torque value corresponding to the uniform reciprocating motion, a foreign matter exists on the coil protection shell of the wireless charging equipment.
In the present embodiment, the first preset torque value may be set to 0.2 Nm; if the detected torque value is 0.2Nm, the poking rod does not touch foreign matters when performing uniform reciprocating motion on the coil protection shell of the wireless charging equipment, and the coil protection shell of the wireless charging equipment does not have the foreign matters; if the detected torque value is not 0.2Nm and is generally greater than 0.2Nm, the fact that the deflector rod touches foreign matters on the coil protection shell of the wireless charging device and does not do uniform reciprocating motion at the same time indicates that the foreign matters exist on the coil protection shell of the wireless charging device.
In this embodiment, can judge whether to be the first predetermined moment value that uniform motion corresponds through the moment value that detects to according to the result of judging in real time can in time discover wireless charging equipment's coil protection casing on the foreign matter, shortened the foreign matter discovery time, and compare infrared identification's foreign matter detection technique and practiced thrift the cost.
Further, in other embodiments, the step S21 is preceded by:
and step S40, sending a detection instruction to a torque sensor so as to receive the torque value of the shifting lever returned by the torque sensor according to the detection instruction in real time.
The torque sensor is also called torque sensor, torquemeter, and is divided into two categories, dynamic and static, wherein the dynamic torque sensor is also called torque sensor, torque speed sensor, non-contact torque sensor, rotation torque sensor, etc. The torque sensor converts the physical change of the torque force into an accurate electric signal.
In this embodiment, the controller sends a detection instruction to the torque sensor, the torque sensor receives the detection instruction and detects the torque value in real time, and the controller receives the torque value of the shift lever returned by the torque sensor according to the detection instruction in real time. According to the moment value of the shifting lever detected and returned in real time by the moment sensor, the controller can judge whether foreign matters exist on the coil protection shell of the wireless charging equipment. When the foreign matter was touched to the driving lever on wireless battery charging outfit's coil protection casing, the moment value of driving lever can the grow, and through the moment value of real-time detection driving lever, the foreign matter can in time be discover.
Referring to fig. 4, fig. 4 is a detailed flowchart of step S30 in the third embodiment of the method for removing foreign objects in a wireless charging device according to the present invention, in this embodiment, the step S30 includes:
step S31, acquiring the weight of the foreign matters through a weight sensor;
in this embodiment, weight sensor links to each other with wireless battery charging outfit, and weight sensor is the device that changes quality signal into measurable signal of telecommunication output, when there is the foreign matter on wireless battery charging outfit's the coil protection casing, and weight sensor can in time acquire the weight of foreign matter on wireless battery charging outfit's the coil protection casing and send the foreign matter weight value to the controller.
And step S32, increasing the detected torque value to a torque value corresponding to the weight of the foreign matters.
In this embodiment, a corresponding relationship between the torque value and the torque value that needs to be increased correspondingly is established, the corresponding torque value can be obtained according to the weight of the foreign object, and the controller increases the torque value to the torque value corresponding to the weight of the foreign object so as to remove the foreign object on the coil protection housing of the wireless charging device through the shift lever. Corresponding torque value can be obtained according to the weight of different foreign matters and the torque value is increased to the corresponding torque value, so that the driving lever can more effectively remove the foreign matters on the coil protection shell of the wireless charging equipment.
Alternatively, the following steps may be performed while performing step S32:
step S321, determining whether the increased torque value exceeds a second preset torque value; if yes, go to step S322;
step S322, an alarm instruction is sent out.
In this embodiment, the second preset torque value is an upper limit value of the output torque of the motor, and is greater than the first preset torque value corresponding to the uniform reciprocating motion in step S23. When the increased torque value is larger than the upper limit value of the motor output torque, the controller sends an alarm instruction to enable the alarm to send an alarm signal. When the increased torque value is larger than the upper limit, the driving lever cannot remove foreign matters on the coil protection shell of the wireless charging equipment at the moment, and manual cleaning is needed; when the increased torque value is smaller than or equal to the upper limit value of the motor output torque value, the controller does not need to send an alarm instruction at the moment, and the controller can also understand that the poking rod can remove foreign matters on the coil protection shell of the wireless charging equipment, and most of the foreign matters can be removed through the poking rod, such as metal, such as iron sheets, pop cans, coins and the like.
In this embodiment, the second preset torque value may be set to 2Nm, the upper limit of the motor output is 2Nm, and when the increased torque value is greater than 2Nm, the controller sends an alarm command; when the increased torque value is less than or equal to 2Nm, the controller need not issue an alarm command. Through setting up the second and predetermine the moment value, guaranteed to carry out artifical feedback in time under the unable circumstances of cleaing away the foreign matter of device, promoted wireless charging equipment's security.
Further, with reference to fig. 4, the step S32 is followed by a step S33;
and step S33, when the increased torque value is detected to be restored to the first preset torque value corresponding to the uniform reciprocating motion, the poking rod is confirmed to remove the foreign matters.
In this embodiment, how to determine that the poking rod removes the foreign object on the coil protection housing of the wireless charging device is mainly determined by whether the torque value is restored to the first preset torque value corresponding to the uniform reciprocating motion in step S23. When the increased torque value is restored to the first preset torque value corresponding to the uniform reciprocating motion of step S23 after a period of time, the shift lever has already removed the foreign matter on the coil protection housing of the charging device. For example, when the increased torque value is detected to return to 0.2nm after a period of time, the driver will clear the foreign object.
In this embodiment, when finding that there is the foreign matter on wireless charging equipment's the coil protection casing, can obtain the foreign matter weight by weight sensor, increase the moment value to the moment value that foreign matter weight corresponds, because the foreign matter is heavier, the moment value that needs to increase is just bigger. The foreign matter weight can be firstly obtained, then the torque value is correspondingly increased, so that the foreign matter can be effectively removed through the shifting lever, the moment value of the shifting lever after the increase is detected in real time, whether the moment value of the shifting lever after the increase is recovered to the moment value when the shifting lever reciprocates at a constant speed is judged, and therefore the shifting lever can be determined to remove the foreign matter existing on the coil protection shell of the wireless charging equipment. When the increased torque value is greater than the torque upper limit, the poking rod cannot clear the foreign matters, and manual treatment is needed. However, if the torque upper limit is not reached, the foreign matter can be automatically removed through the shifting lever, manual intervention is not required when the foreign matter is found every time, and labor cost is saved to a certain extent.
The invention also proposes a computer-readable storage medium on which a computer program is stored. The computer-readable storage medium may be the Memory 10 in fig. 2, and may also be at least one of a ROM (Read-Only Memory)/RAM (Random Access Memory), a magnetic disk, and an optical disk, and the computer-readable storage medium includes several instructions to enable a terminal device (which may be a mobile phone, a computer, a server, a wireless charging device, or a network device) having a processor to execute the method according to the embodiments of the present invention.
