Preferred embodiments of the present disclosure are described in further detail below with reference to the accompanying 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 can also charge the electronic device in a wired manner through a power line. The charging equipment is internally provided with a fan for dissipating heat of a charging assembly in the charging equipment; in one embodiment, the charging assembly includes a wireless charging coil. The electronic device can be a smart terminal or a mobile terminal device equipped with a battery power supply system. The electronic equipment can be a mobile phone, a notebook computer, an ipad, an electronic book reader, an intelligent wearable device, a mobile power supply (such as a charger and a travel charger), an electronic cigarette, a wireless mouse, a wireless keyboard, a wireless earphone, a Bluetooth sound box and other chargeable electronic equipment with a charging function.

In the following embodiments, a control method of the charging apparatus of the present disclosure will be explained.

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 decibel of the sound in the environment and sending the detection result to the CPU.

The fan is arranged in the charging equipment, 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 charging power required for the battery according to the detected voltage, amount of electricity, and temperature of the battery. The CPU of the electronic device sends charging power information required by the battery to the charging device so that the charging device can adjust the output power. The charging device and the electronic device can also perform other data transmission, for example, the charging device can transmit required information to the electronic device, the electronic device collects the information, and transmits the collected result 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 one embodiment, a method of controlling a charging apparatus includes:

21, acquiring a required silence degree in the environment where the charging equipment is located;

and 22, adjusting the rotating speed of the fan according to the required quietness degree.

During the process of charging the electronic device by the charging device, a fan in the charging device generates noise. Therefore, in this step, the degree of silence required by the target object in the environment where the charging apparatus is located is acquired. The target object can be a user or other living and non-living bodies which are sensitive to environmental noise and have quiet requirements.

In the environment of the charging device, the room in which the charging device is operating may be understood as well as a spatial range at a distance from the charging device, for example, a spatial range within 5 meters from the charging device.

The charging equipment can acquire the required silence 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 of the required degree of silence in the environment where the charging device is located includes:

acquiring 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 quiet degree in the environment where the charging equipment is located; and when the output power of the charging equipment is less than the first power, the fan is turned off.

In this embodiment, it is possible to determine whether the required degree of silence in the environment in which the charging device is located needs to be acquired directly by detecting the output power of the charging device.

Referring to fig. 3, fig. 3 is a schematic diagram illustrating charge logic control of an electronic device according to an exemplary embodiment. The "low power charging mode" and the "high power charging mode" are explained here. The low power charging mode refers to the charging device outputting relatively less power (e.g., less than 15W) to charge the battery of the electronic device. The high power charging mode is to say that the charging device is capable of outputting a larger power (for example, more than 25W) to charge the battery in the device to be charged. 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 a normal charging logic of an electronic device, when a battery voltage of the electronic device is between a pre-charging voltage and a constant voltage, and an ambient temperature and a temperature of the electronic device satisfy a condition of a high-power charging mode, the electronic device enters the high-power charging mode. However, as charging progresses, the temperature in the electronic device may increase, and when the temperature in the electronic device 5 is high (e.g., exceeds T1), the electronic device needs to be charged in the medium power mode; and then, when the charging in the medium-power charging mode is continued until the constant-voltage value V1 of the battery, the charging is switched to the low-power charging mode until the battery of the electronic equipment is fully charged.

When the electronic equipment is charged in a low-power mode, the output power of the charging equipment is low, the heat of the transmitting coil is not serious, and the fan can be turned off at the moment to save energy; the electronic device need not acquire the desired degree 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 may be 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 a manufacturer, and the power value is small, so that the normal charging and the safety of the charging can be ensured even if the fan is not turned on.

Referring to fig. 4, fig. 4 is a flowchart illustrating step 21 of fig. 2 according to an embodiment. In another embodiment, the obtaining of the required degree of silence in the environment in which the charging device is located includes:

211, acquiring a charging mode of the electronic equipment; the charging mode comprises a first charging mode and a second charging mode; the charging power required by the electronic equipment in the first charging mode is minimum;

212 when the charging mode of the electronic device is a first charging mode, turning off the fan;

213 obtaining the required degree of silence in the environment where the charging device is located when the charging mode of the electronic device is the second charging mode.

In this embodiment, it is determined whether the required degree of silence in the environment where the charging device is located needs to be acquired 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 device is in the low-power charging mode, the power required to be output by the charging device is relatively small, and the heating value is not large, so that the fan is not started, and noise is not generated.

Of course, the charging mode of the electronic device may be multiple according to different charging logics. The embodiment improves the matching of the electronic equipment charging control logic and the charging device control scheme.

The embodiment improves the intelligence of the control scheme of the charging equipment, 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 the noise generated by the fan is eliminated.

In step 22, only the rotation speed of the fan may be adjusted according to the required degree of quietness, and in one embodiment, in order to improve the operational safety of the charging device, the output power of the charging device may be adjusted while the rotation speed of the fan is adjusted. Specifically, the adjusting 22 the rotation speed of the charging fan according to the required quietness degree includes:

adjusting the speed of the fan, and adjusting the output power of the charging device, based on the desired level of quietness.

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 degree of quietness may be set by the user on the electronic device, for example, a plurality of options of different degrees of quietness may be displayed on a display screen of the electronic device: no need of silence, low silence, medium silence 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 may also be provided on the charging device, such as a button, a knob, a touch screen, or a 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 degree of silence is determined according to the decibel of the environment in which the charging device is located; the decibel of the environment where the charging device is located can reflect the activity of the user, so that the required silence degree of the user is reflected.

The acquiring the required degree of silence in the environment where the charging device is located includes:

214, obtaining decibels of sound in an environment where the charging device is located;

adjusting the speed of the fan, and adjusting the output power of the charging device, based on the desired level of quietness, comprising:

and when the decibel of the sound in the environment where the charging equipment is located is smaller than or equal to a first decibel, reducing the rotating speed of the fan and reducing the output power of the charging equipment.

Specifically, in an example, the decibel of the sound in the environment may be obtained through a microphone provided on the electronic device, and the electronic device transmits the obtained 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 the sound in the environment where the charging device is located and transmitting the decibel data to the control circuit. The sound sensor can be a microphone or a noise sensor.

The first point may be a value set by a manufacturer or a value set by a user. The first divisor may be a fixed constant value or an adjustable value. The user can set the value of the first decibel according to the noise intensity that he can tolerate. In one embodiment, the first decibel value is greater than or equal to 50 db.

In one example, the first decibel value may be set according to the detected intensity of the ambient noise, such that the noise emitted by the fan of the charging device is within a 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 decibel of the sound in the environment where the charging device is located is less than or equal to the first decibel, it indicates that the current environment is quieter, which reflects 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 is started 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 fixed time period. In processing the collected decibel values, an average value can be obtained according to a plurality of decibel values collected within a period of time to serve as a final decibel value, so that the condition that the decibel value is suddenly changed due to interference of abnormal conditions is eliminated.

When the decibel of the sound in the environment where the charging equipment is located is larger than or equal to the first decibel, the current environment is in a noisy state, and the activity of the user basically has no requirement of quiet environment, so that the noise emitted by a fan of the charging equipment does not need to be processed. The fan can be maintained in a constant state at all times.

In another embodiment, the rotation speed of the fan varies according to 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 of 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 of 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. And under the condition that the temperature in the electronic equipment meets the high-power charging mode, the charging device provides power to the electronic equipment according to the charging power allowed by the high-power charging mode. It is also possible that the electronic device battery voltage reaches a constant voltage value and transitions to a low power charging mode, where the charging device provides power to the electronic device at a charging power allowed by the low power charging mode.

Therefore, under the condition of high environmental noise, the electronic equipment does not need to adjust the charging strategy, and only needs to be charged according to the original charging strategy, and correspondingly, the charging equipment only needs to be matched with the charging strategy of the electronic equipment to output power. However, in this embodiment, the rotation speed of the fan is not kept constant, 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 to have less influence on the charging speed while meeting the user's requirement for silence. It should be noted that, 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 processing of reducing the rotation speed of the fan and reducing the output power of the charging device is performed. The electronic device can make a decision about reducing the rotating speed of the fan and reducing the output power of the charging device after analyzing the decibel value based on the decibel value of the sound in the environment, and then the decision is sent to the charging device and executed by the charging device. Or the charging equipment itself obtains the decibel of the sound in the environment, analyzes the decibel value, makes a decision about reducing the rotating speed of the fan and reducing the output power of the charging equipment, and then executes the decision. The method can also be implemented by the charging equipment obtaining the decibel of the sound in the environment from the electronic equipment, and after further analyzing the decibel value, the charging equipment makes a decision about reducing the rotating speed of the fan and reducing the output power of the charging equipment and then executes the decision.

Referring to fig. 6, fig. 6 is a flowchart illustrating step 22 of fig. 2 according to an embodiment. In an embodiment, the reducing the rotation speed of the fan and the reducing the output power of the charging device when the decibel of the sound in the environment where the charging device is located is less than or equal to a first decibel includes:

222, when the decibel of the sound in the environment where the charging device is located is less than or equal to a first decibel, determining an environment type corresponding to the decibel of the sound in the environment where the charging device is located based on a preset corresponding relationship between the decibel of the sound in the environment and the environment type; wherein the environment types comprise a sleep environment and a working environment;

223, when the environment where the charging device is located is the sleep environment, adjusting the rotation speed of the fan down by a first rotation speed, and reducing the charging power;

224, when the environment where the charging device is located is the working environment, adjusting the rotation speed of the fan down 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, for example, the electronic device makes a decision to reduce the rotation speed of the fan and reduce the output power of the charging device, and sends the decision to the charging device. The electronic equipment stores the corresponding relation between the decibel of the sound in the preset environment and the environment type before leaving the factory. Or the corresponding relation between the decibel of the sound in the preset environment set by the user and the environment type. The corresponding relation between the decibel 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 decibel of the sound in the environment and the environment type at any time.

In the correspondence between the decibel of the sound in the environment and the type of the environment, the decibel of the sound in the environment may 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 device is located is the sleep environment, the user has a high requirement on the quiet degree of the environment, and at this time, the rotating speed of the fan needs to be adjusted downward by a large range, or even stopped. Meanwhile, after the rotation speed of the fan is adjusted downward, the output power of the wireless charging device should be adjusted downward to ensure the charging safety.

When the environment where the charging equipment is located is the working environment, the user has a requirement on the quiet degree of the environment at the moment, but the quiet degree is not high, the rotating speed of the fan is reduced slightly at the moment, and the output power of the wireless charging device does not need to be reduced too much so as to reduce the influence on the charging speed.

In another embodiment, the reducing the rotation speed of the fan and the reducing the output power of the charging device when the decibel of the sound in the environment where the charging device is located is less than or equal to the first decibel 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 the fan rotating speed adjusting degree corresponding to the decibel of the sound in the environment where the charging equipment is located based on a preset corresponding relation between the decibel of the sound in the environment and the fan rotating speed adjusting degree; the lower the decibel of sound in the environment where the charging equipment is located is, the greater the degree of down-regulation of the rotating speed of the fan is;

adjusting the rotating speed of the fan according to the determined down-regulation degree of the rotating speed 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 decibel of the sound in the environment where the charging device is located indicates that the user has a greater need for the quietness of the environment, and correspondingly, the greater the degree of downward adjustment of the fan speed is required to reduce the generated noise.

The electronic equipment stores the corresponding relation between the decibel of the sound in the environment and the rotation speed reduction degree of the fan before leaving the factory. Or the corresponding relation between the decibel of the sound in the environment set by the user and the down-regulation degree of the rotating speed of the fan. When the corresponding relation is a slope, the user can adjust the slope of the corresponding relation to adjust the decibel of the sound in each unit environment and the down-regulation amount of the rotating speed of the fan.

Further, in order to ensure the safety of charging, after the rotation speed of the fan is reduced, the output power of the charging equipment can be reduced, so that the heating value is reduced.

In this embodiment, the sound decibel in the environment corresponds to the fan rotation speed down-regulation degree through the corresponding relationship between the sound decibel in the environment and the fan rotation speed down-regulation degree, so that the fan rotation speed down-regulation degree can be more intuitively reflected, and a user can conveniently master the change of the noise volume emitted by the charging equipment.

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 the output power down-regulation degree of the charging equipment corresponding to the decibel of the sound in the environment where the charging equipment is located based on a preset corresponding relation between the decibel of the sound in the environment and the output power down-regulation degree; the lower the decibel of sound in the environment where the charging equipment is located is, the greater the degree of down-regulation of the output power of the charging equipment is;

adjusting the output power of the charging equipment according to the determined output power down-regulation degree of the charging equipment;

In this embodiment, the lower the decibel of the sound in the environment where the charging device is located, the greater the user's requirement for the quietness of the environment, where the output power of the charging device is first adjusted to reduce the amount of heat generated, so that the rotation speed of the fan is reduced.

The electronic equipment stores the corresponding relation between the decibel of the sound in the environment and the output power down-regulation degree before leaving the factory. Or the corresponding relation between the decibel of the sound in the environment set by the user and the output power down-regulation degree. When the corresponding relationship is a slope, the user can adjust the slope of the corresponding relationship to adjust the decibel of sound per unit environment and the amount of down-regulation 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.

In this embodiment, through the corresponding relationship between the decibel of the sound in the environment and the output power down-regulation degree, the output power down-regulation amount corresponding to the decibel of the sound in the environment can be more intuitively reflected, so that the user can grasp the change of the charging speed.

Based on the foregoing embodiment, in order to make the adjustment of the output power of the charging device and the rotation speed of the fan more intelligent, in an embodiment, the adjusting the rotation speed of the fan and the output power of the charging device according to the required degree of silence includes:

determining that a person is present in an environment in which the charging device is located;

under the condition that no person exists in the environment where the charging equipment is located, adjusting the charging power of the equipment to be charged according to the current voltage and the current temperature of the electronic equipment, and setting the rotating speed of the fan according to the charging power of the electronic equipment;

and under the condition that people exist in the environment of the charging equipment, adjusting the rotating speed of the fan and the output power of the charging equipment according to the required silence degree.

In this embodiment, whether a person is present in the environment can be detected by the camera of the electronic device. An infrared detection device may be mounted on the charging device to detect whether a person is present in the environment. The electronic equipment or the charging equipment can be connected to the Internet of things system arranged in the environment to acquire the information whether people exist in the environment.

Under the condition that no person is in the environment of the charging equipment, the user is not influenced by the noise generated by the charging equipment, so that the charging process of the electronic equipment and the charging device can not be adjusted. Specifically, the charging power of the device to be charged may be adjusted according to the current voltage and the current temperature of the electronic device, and the rotation speed of the fan may be set according to the charging power of the electronic device.

And under the condition that people exist in the environment where the charging equipment is located, the noise emitted by the charging equipment can interfere with the user. In this case, therefore, the rotation speed of the fan is adjusted, and the output power of the charging device is adjusted, in accordance with the required degree of quietness.

In addition, according to the scheme, the output power of the charging equipment is adjusted while the rotating speed of the fan is adjusted, so that the safety of the charging process is guaranteed.

In conclusion, the wireless charger disclosed by the invention is high in working flexibility, can improve the matching performance of the user on the requirement of the quiet degree, and can ensure the charging safety.

Based on the control method of the charging device, the present disclosure also provides a control method of an electronic device, and please refer to the embodiment of the control method of the charging device regarding the embodiment of the control method of the electronic device. Referring to fig. 8, fig. 8 is a flowchart illustrating a control method of an electronic device according to an embodiment; the control method of the electronic equipment comprises the following steps:

51, acquiring current charging power;

52, when the allowed charging power is larger than or equal to the second power, acquiring the required silence degree in the environment where the electronic equipment is located;

53, sending the acquired required quiet degree to charging equipment, so that the charging equipment adjusts the rotating speed of the fan and adjusts the output power of the charging equipment according to the required quiet degree; or controlling the rotating speed of a fan in the charging equipment or the output power of the charging equipment according to the required quietness degree.

The charging power of the electronic device may be constant all the time or set according to a charging strategy, where the charging strategy includes a plurality of consecutive charging modes, and each charging mode corresponds to a different charging power. Generally, along the charging process, the charging power corresponding to the charging mode at the earlier stage is larger. For a detailed explanation of the charging strategy, reference is made to the above-described embodiments. The electronic device may determine the charging mode currently being used by detecting the battery voltage, the amount of power, and the temperature of the battery.

Before step 51, it is necessary to determine whether the electronic device is in a wireless charging condition. Step 51 is only performed when the electronic device is in a wireless charging condition. And the electronic device can identify whether the charging condition is met or not by itself.
