The IoT devices may be smart toothbrushes, smart watches, smart bracelets, head-worn devices, smart scales, and the like.

In one embodiment, as shown in fig. 2, a charging method is provided, which is illustrated by applying the method to the electronic device in fig. 1 as an example; the charging method comprises the following steps:

The modes of the electronic device include an NFC communication mode and an NFC charging mode. The NFC communication mode is a mode in which the electronic device performs near field communication, and the NFC charging mode is a mode in which the electronic device multiplexes an existing NFC device to charge the accessory device. The existing NFC device in the electronic equipment comprises an NFC chip and a first antenna, the NFC chip is used for processing an NFC instruction, and the first antenna is used for receiving and transmitting the NFC instruction and transmitting a null carrier carrying energy. The existing NFC device in the electronic device may support a near field communication function, such as reading a tag card, swiping a point of sale (POS) device, and the like.

The corollary equipment is the equipment that matches with electronic equipment. Illustratively, the electronic device is a mobile phone, and the corollary device may be a stylus pen for triggering on a screen of the mobile phone, a smart watch, a smart bracelet, or the like matched with the mobile phone.

The NFC charging distance refers to a maximum distance value within a distance range in which the electronic device performs NFC charging on the accessory device. The preset NFC charging distance may be set as needed. Illustratively, the NFC charging distance of the electronic device to the accessory device is 0 to 5cm (centimeter), and the preset NFC charging distance is 5cm.

It can be understood that the distance between the accessory device and the electronic device is less than or equal to the preset NFC charging distance, which indicates that the accessory device is in a charging state; the electronic equipment receives the response information after sending the detection instruction to the matched equipment, and the indication that the distance between the matched equipment and the electronic equipment is smaller than or equal to the NFC charging distance is shown, namely the matched equipment is also in a charging state.

A hall sensor is a magnetic field sensor made according to the hall effect. The basic principle of the hall sensor is as follows: the Hall sensor is provided with a Hall semiconductor chip, and a constant current I flows from A to B and passes through the Hall semiconductor chip; when the hall semiconductor chip is in a magnetic field environment, the electron current of the constant current I is deflected to one side by the lorentz force when passing through the hall semiconductor chip, so that the hall semiconductor chip generates a potential difference in the transverse Direction (CD), which is a so-called hall voltage. Whether the magnetic field exists can be judged by detecting the Hall voltage through the Hall sensor.

Alternatively, the corollary equipment can include metal, and the distance between metal and hall sensor is inversely proportional to the hall voltage detected by the hall sensor. It will be appreciated that the metal in the kit may generate a magnetic field and thus a hall voltage. Optionally, a metal may also be included in the electronic device. The metal may be a magnet or the like, but is not limited thereto.

The PCB board can be provided with a circuit and an NFC chip, and the NFC chip can realize an NFC instruction interaction function. The metal in the smart phone can also be a magnet, and the PCB in the handwriting pen is a support body of electronic components and is a carrier for electrically interconnecting the electronic components.

The handwriting pen is adsorbed to a preset position of the smart phone through a magnet, and metal is attached to the inner wall of the smart phone at the preset position; the smart phone detects that the Hall voltage is greater than or equal to a preset voltage through the Hall sensor, the fact that the distance between the stylus pen and the smart phone is smaller than or equal to an NFC charging distance is indicated, the stylus pen is in a state of being placed at a preset position, namely the stylus pen meets a charging condition, the smart phone switches the current mode into an NFC charging mode, an existing first antenna is multiplexed through the NFC charging mode, and continuous energy-carrying empty carriers are sent to a second antenna of the stylus pen; the second antenna converts the energy in the null carrier wave into electrical energy and charges the battery in the stylus pen. The preset position can be a groove, and the stylus pen can be accurately embedded into the groove.

And step 204, multiplexing the existing NFC device through the NFC charging mode to charge the corollary equipment.

It can be understood that, the electronic device charges the accessory device by multiplexing the existing NFC device in the NFC charging mode, and in order to improve charging efficiency, the power of the accessory device is smaller than the preset power threshold. The preset power threshold value can be set as required and is a small value.

According to the charging method, if the matched equipment corresponding to the electronic equipment meets the charging condition, the current mode of the electronic equipment is switched to the NFC charging mode, the existing NFC device is reused for charging the matched equipment through the NFC charging mode, the matched equipment is prevented from being charged through new hardware in the NFC charging mode, and the hardware cost of wireless charging can be reduced.

In one embodiment, if a corollary device corresponding to the electronic device meets a charging condition, switching a current mode of the electronic device to an NFC charging mode includes: if the matched equipment corresponding to the electronic equipment meets the charging condition, sending an equipment information request to the matched equipment; and acquiring the equipment information sent by the supporting equipment based on the equipment information request, and if the equipment information is matched with the preset information, switching the current mode of the electronic equipment into the NFC charging mode.

The device information of the accessory device may include a device type, a device identifier, power information of the device, a charging state of the device, and the like of the accessory device. The device identifier may be, without limitation, a name, a model, a pattern, and the like of the device.

For example, the accessory device is a stylus pen, and the device information of the accessory device may include a device type, that is, a stylus pen type, a device model, and the like.

Optionally, the accessory device responds to the received device information request, obtains device information of the accessory device, and sends the device information to the electronic device. After the electronic equipment acquires the equipment information of the matched equipment, matching the equipment information with the stored preset information; if the device information is matched with the preset information, it is indicated that the matching between the matching device and the electronic device is successful, the electronic device can charge the matching device, and the current mode of the electronic device is switched to the NFC charging mode. If the device information is not matched with the preset information, prompt information of unsuccessful matching can be displayed in a screen of the electronic device.

In this embodiment, if the accessory device corresponding to the electronic device satisfies the charging condition, the device information request is sent to the accessory device, the device information sent by the accessory device based on the device information request is acquired, and if the device information matches the preset information, the current mode of the electronic device is switched to the NFC charging mode.

In one embodiment, charging a companion device via an NFC charging mode includes: acquiring the battery power of the matched equipment; determining a charging current based on a battery level of the accessory device; and charging the matched equipment with the charging current through the NFC charging mode.

Optionally, the electronic device determines a current charging node of the accessory device based on the battery capacity of the accessory device; a charging current is determined based on the present charging node.

It can be understood that the charging process comprises trickle, constant current and constant voltage nodes in sequence, and when the electric quantity of the battery is lower, namely the voltage of the battery is lower, trickle charging is adopted; the electric quantity of the battery is increased until the voltage of the battery reaches a first voltage, and constant current charging is adopted; the electric quantity of the battery continues to rise until the voltage of the battery reaches a second voltage, and constant-voltage charging is adopted; wherein the first voltage is less than the second voltage. The charging current of the trickle node is smaller than that of the constant-current node, and the charging current of the constant-voltage node is smaller than that of the constant-current node.

Optionally, the electronic device may convert the charging current into a null carrier carrying energy, and send the null carrier to the accessory device, and the accessory device may convert the energy in the null carrier into electric energy to charge the battery.

In this embodiment, the battery power of the accessory device is obtained, the charging current corresponding to the battery power can be determined based on the battery power of the accessory device, and then the accessory device is charged with the charging current in the NFC charging mode, so that the battery of the accessory device can be more safely protected in the charging process.

In one embodiment, acquiring the battery power of the accessory device includes: sending an electric quantity acquisition request to the corollary equipment at intervals of preset time length or random time length, and receiving the battery electric quantity of the corollary equipment returned by the corollary equipment based on the electric quantity acquisition request; determining a charging current based on a battery level of a companion device, comprising: the charging current is determined based on the battery level of the latest companion device received.

The preset duration can be set as required. For example, the preset time period may be 0.1ms (milliseconds). The random duration may be obtained by a random function.

Optionally, the electronic device sends an electric quantity acquisition request to the accessory device at preset time intervals, and receives the battery electric quantity of the accessory device returned by the accessory device based on the electric quantity acquisition request; and determining the current charging node of the matched equipment based on the received latest battery capacity of the matched equipment, and determining the charging current of the current charging node.

Optionally, if the electronic device determines that the charging node of the accessory device changes based on the received latest battery capacity of the accessory device, the latest charging current of the current charging node is determined, the charging current is adjusted to the latest charging current, and the accessory device is charged with the latest charging current through the NFC charging mode.

For example, if the electronic device determines that the charging node of the accessory device is switched from the trickle node to the constant current node based on the latest battery capacity of the accessory device received, the charging current of the current constant current node is determined, the charging current of the constant current node is adjusted, and the accessory device is charged with the charging current of the constant current node in the NFC charging mode.

In this embodiment, at intervals of a preset time duration or a random time duration, an electric quantity acquisition request is sent to the accessory device, the battery electric quantity of the accessory device returned by the accessory device based on the electric quantity acquisition request is received, and the charging current can be determined based on the received latest battery electric quantity of the accessory device, so that the accessory device is charged with the corresponding charging current under different battery electric quantities, the battery of the accessory device is more safely protected in the charging process, and the charging accuracy is improved.

In one embodiment, an existing NFC device of an electronic device includes a first antenna; charging the corollary equipment, including: transmitting a null carrier carrying energy to a second antenna through a first antenna; the second antenna is used for converting the energy carried by the idle waves into electric energy and charging a battery of the matched equipment.

A null carrier is a waveform without a modulated signal, i.e., a carrier that does not carry command information and provides energy.

Optionally, the accessory device includes a second antenna, and the electronic device sends the null carrier carrying the energy to the second antenna of the accessory device through the first antenna; the second antenna of the corollary equipment receives the empty carrier wave carrying the energy, can convert the energy in the empty carrier wave into electric energy, and charge the battery in the corollary equipment.

Optionally, the electronic device obtains a charging current for the accessory device, determines a transmission rate of the null carrier based on the charging current, and transmits the null carrier carrying energy to the second antenna at the transmission rate; wherein the charging current and the transmission rate of the idle wave have a positive correlation.

That is, the greater the charging current of the companion device by the electronic device, the greater the transmission rate at which the electronic device transmits the null carrier carrying energy to the second antenna.

In this embodiment, the electronic device sends the idle carrier carrying energy to the second antenna through the first antenna, so that the second antenna in the accessory device can convert the energy carried by the idle carrier into electric energy, and charge a battery of the accessory device, thereby accurately implementing NFC charging of the accessory device by the electronic device.

In one embodiment, the method further comprises: and if the corollary equipment corresponding to the electronic equipment meets the non-charging condition, switching the current mode of the electronic equipment into the NFC communication mode.

The non-charging condition comprises that the distance between the matched equipment and the electronic equipment is larger than a preset NFC charging distance, and/or no response information is received after a detection instruction is sent to the matched equipment.

Optionally, if the hall sensor detects that the hall voltage is smaller than the preset voltage, it indicates that the distance between the accessory device and the electronic device is greater than the preset NFC charging distance, and the accessory device meets the non-charging condition.

It can be understood that the distance between the accessory device and the electronic device is greater than the preset NFC charging distance, which indicates that the accessory device is in a non-charging state; after the electronic equipment sends the detection instruction to the matched equipment, the response information is not received, and the fact that the distance between the matched equipment and the electronic equipment is larger than the NFC charging distance means that NFC charging cannot be carried out, namely the matched equipment is also in a non-charging state. The NFC charging distance is also referred to as an NFC communication distance.

Optionally, the non-charging condition includes that the electronic device does not receive the response message after sending the at least two detection instructions to the accessory device. For example, if the electronic device repeatedly sends the detection instruction to the accessory device three times without receiving the response message, it indicates that the distance between the accessory device and the electronic device is greater than the NFC charging distance. It can be understood that the electronic device sends the detection instruction to the accessory device at least twice, and if no response information is received, the accessory device is in a non-charging state, so that the problem of false detection when the electronic device detects the distance between the electronic device and the accessory device or the problem of false detection caused by the shaking of the accessory device can be prevented, and whether the accessory device meets the non-charging condition or not can be determined more accurately. Meanwhile, the electronic equipment sends a detection instruction to the corollary equipment to detect whether the corollary equipment meets the non-charging condition or not, so that the hardware cost of the Hall sensor and the like can be saved.

Optionally, the non-charging condition may further include at least one of that the electric quantity of the accessory device is higher than a third electric quantity threshold, that the electric quantity of the electronic device is lower than a fourth electric quantity threshold, and a non-charging instruction triggered by a user; wherein the third charge threshold is higher than the fourth charge threshold.

Optionally, if the electronic device detects that the corresponding corollary device meets the non-charging condition, determining a current mode; if the current mode is not the NFC communication mode, switching the current mode to the NFC communication mode; if the current mode is the NFC communication mode, mode switching may not be performed.

It should be noted that, if it is detected that the accessory device corresponding to the electronic device satisfies the non-charging condition, the current mode of the electronic device is switched to the NFC communication mode, and the electronic device may perform near field communication with the accessory device through the NFC communication mode, or may perform near field communication with another near field communication device through the NFC communication mode, which is not limited herein.

In an embodiment, as shown in fig. 4, the electronic device is a smart phone, and the supporting device is a stylus pen for example. If the stylus pen is taken down from the smart phone, namely the stylus pen is in a take-down state, the distance between the stylus pen and the smart phone is larger than the NFC charging distance, the stylus pen meets a non-charging condition, the smart phone can switch the current mode into an NFC communication mode, and in the NFC communication mode, the smart phone sends an NFC instruction to a second antenna in the stylus pen through a first antenna and receives the NFC instruction sent by the second antenna of the stylus pen through the first antenna.

In another embodiment, the electronic device is a smart phone, and the accessory device is a smart band. If the response information of the smart band is not received after the smart phone sends the detection information to the smart band, the smart band meets the non-charging condition, the current mode of the smart phone can be switched to the NFC communication mode, and in the NFC communication mode, the smart phone sends the NFC instruction to a second antenna in the smart band through a first antenna and receives the NFC instruction sent by the second antenna of the smart band through the first antenna.

In another embodiment, as shown in fig. 5, the electronic device is a smart phone, and the accessory device is a stylus pen. If the handwriting pen meets the non-charging condition, if the electric quantity of the handwriting pen reaches 100%, the smart phone switches the current mode into the NFC communication mode, and the smart phone can perform near field communication with the smart watch through the NFC device.

For example, the near field communication device may be a stylus pen, a door access device, a subway gate, or other mobile phone, and the like, but is not limited thereto.

It can be understood that, in the process of charging the accessory device by the electronic device multiplexing the existing NFC device, near field communication cannot be performed with the near field communication device through the NFC device, and therefore if it is detected that the electronic device needs to perform near field communication with the near field communication device, prompt information is displayed for prompting a user to operate the accessory device to meet a non-charging condition, that is, the electronic device does not charge the accessory device, and then the electronic device can switch the NFC charging mode to the NFC communication mode, and perform near field communication with the near field communication device by using the NFC device.

When the distance between the stylus pen and the smart phone is larger than the NFC distance, the stylus pen meets the non-charging condition, the smart phone switches the NFC charging mode into the NFC communication mode, and near field communication is carried out between the smart phone and the smart watch in the NFC communication mode.
