Preferred embodiments of the present disclosure are further elaborated below in conjunction with the drawings of the present specification.
The present disclosure proposes a charging device, which may be a wireless charging device, for wirelessly charging an electronic device; of course, the charging device may also perform wired charging on the electronic device through the power cord. The charging equipment is internally provided with a fan which is used for radiating a charging assembly in the charging equipment; in one embodiment, the charging assembly includes a wireless charging coil. The electronic device may be an intelligent terminal or a mobile terminal device equipped with a battery-powered system. The electronic device can be chargeable electronic devices with charging functions, such as a mobile phone, a notebook computer, an ipad, an electronic book reader, intelligent wearable devices, a mobile power supply (such as a charger, a travel charger), an electronic cigarette, a wireless mouse, a wireless keyboard, a wireless earphone, a Bluetooth sound box and the like.
In the following embodiments, a control method of the charging device of the present disclosure will be described.
Referring to fig. 1, fig. 1 is a schematic structural diagram of an electronic device according to an embodiment. The electronic device in fig. 1 has a housing 11, a display 12, and a main control board 13 with a CPU thereon. One or more microphones electrically connected with the CPU are arranged in the electronic equipment and used for detecting the decibels of sound in the environment and sending the detection result to the CPU.
The charging equipment is internally provided with a fan, the charging equipment is used for charging the electronic equipment, and the charging equipment and the electronic equipment can communicate. In an embodiment, the charging device and the electronic device are capable of transmitting charging information. The electronic device has a battery therein, and a CPU of the electronic device can detect the voltage, the amount of electricity, and the temperature of the battery. And the CPU can determine the required charging power of the battery based on the detected voltage, amount of electricity, and temperature of the battery. The CPU of the electronic device transmits charging power information required by the battery to the charging device, so that the charging device adjusts the output power. The charging device and the electronic device can also transmit other data, for example, the charging device can send required information to the electronic device, the electronic device collects the information, and the collected result is sent back to the charging device.
Referring to fig. 2, fig. 2 is a flowchart illustrating a control method of a charging device according to an embodiment. In an embodiment, the method for controlling a charging device includes:
21, acquiring the required quietness in the environment where the charging device is located;
22, adjusting the rotational speed of the fan according to the required degree of silence.
During the process of charging the electronic device by the charging device, noise is generated by the fan in the charging device. Thus, in this step, the degree of silence required for the target object in the environment where the charging device is located is acquired. The target object may be a user, or other living and non-living body that is sensitive to environmental noise and has a quiet need.
In the context of the charging device it is understood that the charging device is in the room in which it is operating, and also that a spatial extent is a distance from the charging device, for example within 5 meters from the charging device.
The charging device can acquire the required quietness degree in the environment only under the working condition. In another embodiment, in order to make the operation of the charging device more intelligent, the obtaining the required quietness in the environment where the charging device is located includes:
obtaining the output power of the charging equipment;
When the output power of the charging equipment is larger than or equal to the first power, acquiring the required quietness degree in the environment where the charging equipment is located; and when the output power of the charging equipment is smaller than the first power, turning off the fan.
In this embodiment, it is possible to determine whether it is necessary to obtain the required degree of silence in the environment in which the charging device is located, directly by detecting the output power of the charging device.
Referring to fig. 3, fig. 3 is a schematic diagram illustrating a charging logic control of an electronic device according to an exemplary embodiment. The "low power charging mode" and the "high power charging mode" will be described herein. A low power charging mode refers to a charging device outputting relatively little power (e.g., less than 15W) to charge a battery of an electronic device. The high power charging mode refers to that the charging device can output a larger power (e.g., greater than 25W) to charge the battery in the charging device. The electronic device may also have a medium power charging mode, where the power output by the charging device corresponding to the medium power charging mode is between the low power charging mode and the high power charging mode (e.g., less than or equal to 25W, greater than or equal to 15W).
Illustratively, in the usual charging logic of an electronic device, the electronic device enters a high power charging mode when the electronic device battery voltage is between the pre-charge voltage and the constant voltage, and the ambient temperature and the electronic device temperature satisfy the high power charging mode. However, as the charging proceeds, the temperature in the electronic device becomes higher, and when the temperature in the electronic device 5 is higher (e.g. exceeds T1), the electronic device needs to be charged in the medium power mode; then charging in the medium power charging mode is continued until the constant voltage value V1 of the battery, and the charging is switched to the low power charging mode until the battery of the electronic device is fully charged.
When the electronic equipment is in a low-power mode for charging, the power output by the charging equipment is small, the heating of the transmitting coil is not serious, and the fan can be turned off at the moment so as to save energy; the electronic device need not acquire the required level of silence at this time. Based on this, the first power may be the output power of the charging device when the electronic device is in the low-power charging mode, or the output power of the charging device when the electronic device is in the medium-power charging mode. The first power may also be a power value set by a user or set by a manufacturer, and the power value is smaller, so that normal charging and charging safety can be ensured even if the fan is not started.
Referring to fig. 4, fig. 4 is a flowchart illustrating step 21 in fig. 2 according to an embodiment. In another embodiment, the acquiring the required silence level in the environment where the charging device is located includes:
211, acquiring a charging mode of the electronic equipment; the charging modes comprise a first charging mode and a second charging mode; the electronic equipment has the minimum required charging power in the first charging mode;
212, when the charging mode of the electronic equipment is a first charging mode, turning off a fan;
213, when the charging mode of the electronic device is the second charging mode, obtaining the required quietness in the environment where the charging device is located.
In this embodiment, it is determined whether it is necessary to acquire the required degree of silence in the environment in which the charging device is located, according to the charging mode of the electronic device. The first charging mode is a low power charging mode and the second charging mode may be a high power mode or a medium power charging mode. When the electronic equipment is in the low-power charging mode, the power required to be output by the charging equipment is relatively small, and the heating value is not large, so that a fan can not be started, and noise can not be generated.
Of course, the charging mode of the electronic device may be plural according to the charging logic. The embodiment improves the matching of the charging control logic of the electronic device and the control scheme of the charging device.
According to the embodiment, the intellectualization of the control scheme of the charging equipment is improved, and when the output power of the charging equipment is smaller or the electronic equipment is in a low-power mode, the heating value of the charging coil in the charging equipment is smaller, so that the fan can be turned off, and noise generated by the fan is eliminated.
In step 22, only the rotation speed of the fan may be adjusted according to the required silence degree, and in an embodiment, in order to improve the operation safety of the charging device, the output power of the charging device may be adjusted while adjusting the rotation speed of the fan. Specifically, the adjusting the rotation speed of the charging fan according to the required silence degree 22 includes:
and adjusting the rotating speed of the fan and the output power of the charging equipment according to the required quietness degree.
There are various degrees of silence required to be acquired in the environment in which the charging device is located. In one embodiment, the desired level of silence may be set by the user on the electronic device, e.g., a number of options of varying levels of silence may be displayed on the display screen of the electronic device: no quiet requirement, low and medium and high silence. After the user selects, the electronic device sends the quiet requirement selected by the user to the charging device.
Of course, a receiving unit, such as a button, knob, touch screen, user may also be provided on the charging device, and the user may also select the desired degree of silence directly on the charging device.
Referring to fig. 5, fig. 5 is a flowchart illustrating step 21 in fig. 2 according to another embodiment. In another embodiment, the required level of silence is determined based on the decibels of the environment in which the charging device is located; the decibel of the environment in which the charging device is located can reflect the activity of the user, thereby reflecting the degree of silence required by the user.
The obtaining the required quietness degree in the environment where the charging device is located includes:
214, acquiring the decibel of sound in the environment where the charging equipment is located;
22, said adjusting the rotational speed of said fan, and adjusting the output power of said charging device, according to said desired level of silence, comprising:
And when the decibel of sound in the environment where the charging equipment is positioned is smaller than or equal to the first decibel, reducing the rotating speed of the fan and reducing the output power of the charging equipment.
Specifically, in an example, the electronic device may acquire the decibel of the sound in the environment through a microphone on the electronic device, and then the electronic device transmits the acquired decibel information to the charging device.
In another example, the charging device further comprises a control circuit and a sound sensing element, wherein the control circuit is electrically connected with the fan and the wireless charging assembly; the sound sensing element is used for detecting the decibel of sound in the environment where the charging device is located and transmitting decibel data to the control circuit. The sound sensing element may be a microphone or a noise sensor.
The first decibel may be a value set by the manufacturer or a value set by the user. The first decibel may be a fixed value or may be an adjustable value. The user may set the value of the first decibel based on the noise strength he can tolerate. In one embodiment, the first decibel value is greater than or equal to 50db.
In one example, the value of the first decibel may be set based on the intensity of the detected ambient noise such that the noise emitted by the charging device fan is within the range allowed by the user. The value of the first decibel may be less than, equal to, or slightly greater than the value of the ambient noise.
When the db of sound in the environment where the charging device is located is less than or equal to the first db, the current environment is quiet, reflecting that the user may have some requirements on the quietness of the environment, so in this embodiment, in this case, the rotation speed of the fan starts to be reduced, and the output power of the charging device is reduced.
It should be noted that, when obtaining the decibel of the sound in the environment where the charging device is located, the decibel of the sound in the environment may be obtained once every a fixed period of time. In the processing of the collected decibel values, an average value can be obtained according to a plurality of decibel values collected in a period of time to be used as a final decibel value, so that the interference of abnormal conditions is eliminated, and the situation of abrupt change of the decibel values is caused.
When the decibel of the sound in the environment where the charging equipment is located is greater than or equal to the first decibel, the current environment is in a noisy state, and the activities performed by the user basically have no requirement of environmental silence, so that the noise emitted by a fan of the charging equipment can be not processed. The fan can be maintained in a constant state at all times.
In another embodiment, the rotational speed of the fan may vary depending on the output power of the charging device. Specifically, after the step of obtaining the decibel of the sound in the environment where the charging device is located, the method further includes:
When the sound decibel in the environment where the charging equipment is located is larger than the first decibel, adjusting and reducing the output power of the charging equipment according to the current voltage and the current temperature of the electronic equipment;
And adjusting the rotating speed of the fan according to the output power of the charging equipment.
In this embodiment, when the sound decibel in the environment where the charging device is located is greater than the first decibel, the electronic device still receives the power output by the charging device according to the original charging policy. In the case where the temperature within the electronic device satisfies the high-power charging mode, the charging device supplies power to the electronic device in accordance with the charging power allowed by the high-power charging mode. It is also possible that the battery voltage of the electronic device reaches a constant voltage value and shifts to a low power charging mode, where the charging device supplies power to the electronic device with charging power allowed by the low power charging mode.
Therefore, under the condition that the environmental noise is large, the electronic equipment does not need to adjust the charging strategy, and only needs to charge according to the original charging strategy, and correspondingly, the charging equipment only needs to cooperate with the charging strategy of the electronic equipment to output power. However, in this embodiment, the rotation speed of the fan is not kept unchanged, but is adjusted according to the output power of the charging device, when the output power is larger, the rotation speed of the fan can be kept higher, and when the output power is smaller, the rotation speed of the fan can be reduced, so as to save energy.
In the following three embodiments, when the decibel of the sound in the environment where the charging device is located is less than or equal to the first decibel, the control scheme is optimized, so that the charging speed is less affected while the user's quiet requirement level is met. It should be noted that, when the db of the sound in the environment where the charging device is located is less than or equal to the first db, the processing of reducing the rotation speed of the fan and reducing the output power of the charging device is performed. The decision about reducing the rotational speed of the fan and reducing the output power of the charging device can be made by the electronic device based on the decibels of the sound in the environment and analyzed by the decibel value, and then sent to the charging device for execution by the charging device. Or the method may be that the charging device itself obtains the decibel of the sound in the environment, analyzes the decibel, makes a decision about reducing the rotation speed of the fan and reducing the output power of the charging device, and then executes the decision. The method may further include the steps that the charging device obtains a decibel of sound in the environment from the electronic device, the charging device further analyzes the decibel, makes a decision about reducing the rotation speed of the fan and reducing the output power of the charging device, and then the decision is executed.
Referring to fig. 6, fig. 6 is a flow chart illustrating step 22 of fig. 2 according to an embodiment. In an embodiment, when the db of the sound in the environment where the charging device is located is less than or equal to the first db, reducing the rotation speed of the fan and reducing the output power of the charging device includes:
222, determining an environment type corresponding to the decibel of the sound in the environment where the charging equipment is located based on a corresponding relation between the decibel of the sound in the preset environment and the environment type when the decibel of the sound in the environment where the charging equipment is located is smaller than or equal to the first decibel; wherein the environment type comprises a sleeping environment and a working environment;
223, when the environment where the charging device is located is the sleeping environment, adjusting the rotation speed of the fan downwards by a first rotation speed, and reducing the charging power;
224, when the environment where the charging equipment is located is the working environment, regulating the rotation speed of the fan downwards by a second rotation speed, and reducing the charging power; wherein the first rotational speed is greater than the second rotational speed.
In this embodiment, the decision of the electronic device to reduce the rotational speed of the fan and to reduce the output power of the charging device is taken as an example for sending to the charging device. Before leaving the factory, the electronic equipment stores the corresponding relation between the decibels of sound in the preset environment and the environment types. The corresponding relation between the decibel of sound in the preset environment and the environment type can be set by the user. The corresponding relation between the decibels of the sound in the environment and the environment type is more than two groups, and the user can also increase or delete the corresponding relation between the decibels of the sound in the environment and the environment type at any time.
In the corresponding relationship between the decibels of the sound in the environment and the environment type, the decibels of the sound in the environment can be a range. In one example, 20-40db corresponds to a sleep environment: 40-50db corresponds to the working environment.
When the environment where the charging equipment is located is the sleeping environment, the user has higher requirements on the quietness of the environment, and the rotating speed of the fan needs to be adjusted to be larger in amplitude or even stopped. Meanwhile, after the rotation speed of the fan is adjusted downwards, in order to ensure the safety of charging, the output power of the wireless charging device should also be adjusted downwards.
When the environment where the charging equipment is located is the working environment, the user has requirements on the quietness degree of the environment, but the quietness degree is not higher, the rotating speed of the fan is adjusted downwards, and the output power of the wireless charging device does not need to be adjusted downwards too much, so that the influence on the charging speed is reduced.
In another embodiment, when the db of the sound in the environment where the charging device is located is less than or equal to the first db, reducing the rotation speed of the fan and reducing the output power of the charging device includes:
When the decibel of the sound in the environment where the charging equipment is located is smaller than or equal to a first decibel, determining a fan rotating speed adjusting degree corresponding to the decibel of the sound in the environment where the charging equipment is located based on a corresponding relation between the preset decibel of the sound in the environment and the fan rotating speed down-adjusting degree; the lower the decibel of sound in the environment where the charging equipment is located, the greater the degree of the downward adjustment of the rotating speed of the fan;
adjusting the rotating speed of the fan according to the determined rotating speed down-regulating degree of the fan;
and adjusting the output power of the charging equipment according to the rotating speed of the fan.
In this embodiment, the lower the sound decibel in the environment where the charging device is located, the greater the user's demand for the quietness of the environment, and correspondingly, the greater the fan rotation speed down-regulation is required to reduce the noise generated.
Before leaving the factory, the electronic equipment stores the corresponding relation between the decibels of sound in the environment and the rotation speed down-regulating degree of the fan. The corresponding relation between the decibel of the sound in the environment set by the user and the rotation speed down-regulating degree of the fan can also be set. When the corresponding relation is oblique, the user can adjust the slope of the corresponding relation to adjust the decibel of sound in each unit environment and the down-regulating quantity of the rotating speed of the fan.
Further, in order to ensure the safety of charging, after the rotation speed of the fan is adjusted down, the output power of the charging device can be reduced to reduce the heating value.
In the embodiment, through the corresponding relation between the decibels of the sound in the environment and the down-regulating degree of the rotating speed of the fan, the down-regulating quantity of the rotating speed of the corresponding fan can be more intuitively reflected by the decibels of the sound in the environment, and therefore the user can grasp the change of the noise quantity emitted by the charging equipment.

adjusting the output power of the charging equipment according to the determined output power down-regulation degree of the charging equipment;
and adjusting the rotating speed of the fan according to the output power of the charging equipment.
In this embodiment, the lower the decibel of sound in the environment where the charging device is located, the greater the demand of the user for the quietness of the environment, where the output power of the charging device is first adjusted to reduce the heating value, so that the rotation speed of the fan is reduced.
Before leaving the factory, the electronic equipment stores the corresponding relation between the decibel of sound in the environment and the down-regulating degree of the output power. The corresponding relation between the decibel of the sound in the environment set by the user and the down-regulating degree of the output power can also be adopted. When the corresponding relation is a sloping line, the user can adjust the slope of the corresponding relation to adjust the decibel of sound in each unit environment and the down-regulating quantity of the output power.
Further, when the output power of the charging device is reduced, the rotation speed of the fan is allowed to be reduced.
