In the electronic device 100 , the processing unit 310 may execute instructions to control various modules of the electronic device 100 to implement various functional applications and data processing of the electronic device 100 . For example, the processing unit 310 may be the processor 110 shown in FIG. 3A .

The wireless short-range data transmission unit 311 may be used to establish a data connection with the external device 200 and perform wireless short-range data transmission. For example, the wireless short-range data transmission unit 311 may correspond to the wireless communication module 160 shown in FIG. 3A . In terms of working modes, the electronic device 100 may include a data reception mode and a data transmission mode. Correspondingly, the wireless short-range data transmission unit 311 may include a data receiving unit and a data sending unit, which are respectively used for receiving and transmitting wireless data. That is to say, through the wireless short-range data transmission unit 311 , the electronic device 100 can not only transmit wireless data to the external device 200 , but also receive wireless data from the external device 200 .

The wireless short-range data transmission unit 311 may include a baseband part, a radio frequency part, and a short-range transmission antenna. The short-distance transmission antenna may include a receiving end antenna corresponding to the data receiving unit and a transmitting end antenna corresponding to the data transmitting unit. The wireless short-range data transmission unit 311 may specifically be in the form of a chip, or may be implemented by a set of circuits. The following description will be given by taking the wireless short-range data transmission unit 311 as an example of a wireless short-range data transmission chip.

When the electronic device 100 sends wireless data to the external device 200, the baseband part encapsulates the signal provided by the processor 110, including packetizing the buffer data and the data transmitted by the interface, adding packet headers, parity bits, and the like. Then, the encapsulated envelope data is subjected to high-frequency carrier modulation in the radio frequency unit part. There are various modulation modes, such as amplitude shift keying (ASK) mode, frequency shift keying (FSK) mode, or phase shift keying (PSK) mode. The modulated signal is a high-frequency carrier single-ended signal. Then, the modulated signal is transmitted through the short-distance transmission antenna at the transmitting end. When the electronic device 100 receives wireless data from the external device 200, the short-range transmission antenna at the receiving end receives the wireless signal, and the low-noise amplifier at the radio frequency front-end amplifies the received wireless signal, (the amplified wireless signal is amplified by the radio frequency unit part.

For the appearance and waterproof performance, the chip can be placed on other planes except the screen inside the casing. Moreover, in order to avoid the influence of other circuits in the electronic device 100 on the wireless short-range data transmission unit 310, other circuits should be kept away from the wireless short-range data transmission chip. For example, the distance between other circuits and the wireless short-range data transmission chip should be greater than or equal to 1 mm (millimeters). The short-distance transmission antenna should avoid the clearance area of other antennas of the electronic device 100 (eg, the antenna 1 coupled with the mobile communication module in FIG. 3A ), so as to avoid influence on other communication performance of the electronic device 100 .

The wireless short-range data transmission unit 311 may perform wireless data transmission based on low-power, short-range, and high-speed communication methods such as millimeter wave communication, visible light communication (eg, laser communication) or infrared communication. For example, when using millimeter wave communication, the bidirectional transmission rate can be greater than or equal to 12 Gbps. One-way (ie, the receiving direction or the sending direction) transmission rate can reach 6Gbps. The distance between the short-range transmission antenna of the electronic device 100 and the short-range transmission antenna of the external device 200 may be less than or equal to a preset distance, for example, 1 cm (centimeter). Short-range wireless transmission makes communication content more private. In addition, short-distance wireless data transmission requires less signal transmission power, so the power consumption of the electronic device 100 is small (for example, one-way transmission power≤40mw).

Exemplarily, as shown in FIG. 4A , the wireless short-range data transmission unit 311 on the electronic device 100 and the wireless short-range data transmission unit 321 of the external device 200 are located at the edge positions of the electronic device 100 and the external device 200 , respectively. The polarization directions of the short-distance transmission antenna 311a and the short-distance transmission antenna 321a shown by the cylinder are both vertical directions.

The wireless power control unit 313 may specifically be a chip, or may be implemented by a set of circuits. In terms of working modes, the electronic device 100 may include a wireless power receiving mode and a wireless power transmitting mode. Correspondingly, the wireless power transmission unit 312 may include a wireless power receiving unit and a wireless power transmitting unit.

The wireless power receiving unit may be used to receive wireless power transmitted by the external device 200 , so as to supply power to the electronic device 100 and charge the battery 316 . The wireless power receiving unit may be used to transmit wireless power to the external device 200 to supply power to the external device 200 or to charge the battery 326 of the external device 200 . That is, through the wireless power transmission unit 312 , the electronic device 100 can not only receive charging input from the external device 200 , but also charge the external device 200 .

For example, the wireless power transmission unit 312 and the wireless power control unit 313 may correspond to the charging management module 140 , the power management module 141 , the charging output module 143 and the like shown in FIG. 3A .

The wireless power transmission unit 312 shown in FIG. 3B may specifically include a wireless coil, a DC/AC power converter (ie a switch circuit) and a resonant transmission circuit in the wireless power transmission unit, and a rectifier bridge circuit in the wireless power reception unit , resonant matching circuits and voltage conversion components and other devices. When the electronic device 100 transmits wireless power to the external device 200 (for example, when charging the external device 200 ), referring to FIG. 3C , the power provided by the battery 316 is transmitted to the wireless coil through the DC/AC power converter in the wireless power transmitting unit, and the wireless The coil converts electrical energy into magnetic energy and sends it out. When the electronic device 100 receives wireless power from the external device 200 (for example, when receiving charging from the external device 200 ), referring to FIG. 3C , the electronic device 100 receives magnetic energy through the wireless coil, converts the magnetic energy into electrical energy, and matches the resonance through the wireless power receiving unit. Devices such as circuits and rectifier bridge circuits are processed, and then converted into a supply voltage or a battery charging voltage by a voltage conversion device. The supply voltage is used to power the electronic device 100 , and the battery charging voltage is used to charge the battery 316 .

Among them, the wireless coil can have various forms, for example, it can be a planar coil or a solenoid with a magnetic core. The wireless coil may be located inside the housing on the back of the device. In addition, the higher the degree of alignment between the wireless coils of the electronic device 100 and the external device 200 (for example, the center alignment of the two wireless coils), the smaller the distance, the higher the coupling coefficient of the wireless coils, and the higher the power conversion efficiency. , the greater the maximum power value of wireless power transmission. The device that transmits wireless power to other devices may be referred to as a wireless power transmitter, and the device that receives wireless power transmitted by other devices may be referred to as a wireless power receiver. The sizes of the wireless coils of the electronic device 100 and the external device 200 are similar, or the size of the wireless coil of the wireless power receiving end is smaller than the size of the wireless coil of the wireless power transmitting end.

Exemplarily, as shown in FIG. 4A , the wireless coil 312a and the wireless coil 322a are located inside the rear casings of the electronic device 100 and the external device 200, respectively. The wireless coil 312a and the wireless coil 322a are planar coils, and are disposed parallel to the planes where the electronic device 100 and the external device 200 are located, respectively.

The connection auxiliary unit 314 shown in FIG. 3B can be used to assist the electronic device 100 to detect the external device 200, identify the device information of the external device 200, and automatically determine the power transmission direction and wireless data parameters. For example, the connection auxiliary unit 314 may correspond to an NFC module, an RFID module in the wireless communication module 160 shown in FIG. 3A , or a Hall sensor in the magnetic sensor 180D, and the like. The connection auxiliary unit may also be referred to as a detection component or a detection interface.

For example, the connection auxiliary unit 314 may be an electronic label scanner, and the matched connection auxiliary unit 324 may be an electronic label. Exemplarily, the connection auxiliary unit 314 may be an NFC sensing module, and the matched connection auxiliary unit 324 may be an NFC tag. In another example, the connection auxiliary unit 314 may be an RFID scanner, and the matched connection auxiliary unit 324 may be an RFID tag. For another example, the connection auxiliary unit 314 may be a Hall device, and the matched connection auxiliary unit 324 may be a magnetic element.

Exemplarily, the corresponding perspective views in the case where the electronic device 100 and the external device 200 are about to be installed together can be referred to FIG. 4C and FIG. 4D . The connection auxiliary unit 314 on the electronic device 100 may be an NFC sensing module. As shown in FIG. 4C and FIG. 4D , the NFC sensing module has a certain effective sensing area. The effective sensing area of the NFC sensing module is located on the back of the electronic device 100 (ie, the non-screen surface). The NFC sensing module includes an antenna, and the antenna can be a slot antenna installed on the upper edge of the mobile phone, or it can be in other forms such as a coil. The connection auxiliary unit 324 on the external device 200 may be an NFC tag. NFC tags can include chips and induction coils. For example, the chip of the NFC tag may be an Ntag213 chip, an Ntag215 chip, an Ntag216 chip, or the like. Here, the size of the NFC tag is 10mm×20mm.

In the perspective views shown in FIGS. 4C and 4D , the connection auxiliary unit 314 on the electronic device 100 can also be replaced with a lower-cost Hall device, and the connection auxiliary unit 324 on the external device 200 can also be replaced with a magnetic element. Among them, the Hall device can be used to measure the change of the magnetic field strength, and the semiconductor manufacturing material of the Hall device can include germanium, silicon, gallium arsenide, indium arsenide or indium antimonide, etc. The magnetic element can usually be composed of windings and a magnetic core, and is usually a permanent magnet material, such as NdFeB magnets, Samarium Cobalt magnets, AlNiCo magnets, and the like. When the magnetic element is close to the Hall device, the Hall device can detect the change of the magnetic field strength in a specific direction. That is, when the Hall device detects a change in the magnetic field strength in a specific direction, it can be determined that a magnetic element is detected.

Moreover, in order to avoid interference, the antenna and the Hall device of the NFC sensing module in the electronic device 100 need to be far away from the chip in the wireless short-range data transmission unit 311 . For example, the distance between the antenna and the Hall device of the NFC sensing module should be greater than 3mm from the chip in all directions. Likewise, the electronic tags and magnetic components in the external device 200 also need to be far away from the chips in the wireless short-range data transmission unit 321 . Moreover, the effective working directions of the antenna and the magnetic element of the NFC sensing module are both facing the back side of the electronic device.

The mounting unit 315 shown in FIG. 3B cooperates with the mounting unit 325 to mount the electronic device 100 and the external device 200 together, so that the short-distance transmission antennas of the electronic device 100 and the external device 200 can be aligned, so that the electronic device 100 It can be aligned with the wireless coil of the external device 200; so that the connection auxiliary unit of the electronic device 100 and the external device 200 can induce mutual induction; so that the distance between the electronic device 100 and the external device 200 is within the range of wireless short-range communication methods such as millimeter wave communication. within the communication range. That is to say, after the electronic device 100 and the external device 200 are installed together, they can meet the wireless short-range data transmission and wireless power transmission, and the alignment requirements for the wireless short-range data transmission unit 321 and the wireless coil.

In addition, by fixing the electronic device 100 and the external device 200 together by the mounting unit 315, relative movement between the electronic device 100 and the external device 200 can be avoided, thereby causing the position of the antenna, the position of the wireless coil or the distance between the devices to change , which affects the effect of wireless power transmission and wireless data transmission between devices.

For example, the mounting unit 315 may be a mounting component disposed inside the electronic device 100 so as not to affect the appearance of the electronic device. Exemplarily, the mounting unit 315 may be a magnetic component. The mounting unit 315 may also be other mounting components such as a suction cup or a buckle, and the specific form of the mounting unit 315 is not limited in the embodiment of the present application. The mounting unit 315 may be located at the edge of the electronic device 100, inside the housing on the back or outside the housing on the back. The mounting unit 315 may be one component, and may include multiple components in different locations. When the mounting unit 315 includes multiple components in different positions, the electronic device 100 and the external device 200 can be better fixed and aligned. The installation part 315 and the installation part 325 can guide the user to correctly install the electronic device 100 and the external device 200 .

Exemplarily, as shown in FIG. 4A , the mounting unit 315 and the mounting unit 325 are respectively located inside the back shells of the electronic device 100 and the external device 200 , and respectively include two components at different positions. For example, the mounting unit 315 may be a component using a hard magnetic material, and the mounting unit 325 may be a component using a soft magnetic material; or, the mounting unit 315 may be a component using a soft magnetic material, and the mounting unit 325 may be a component using a hard magnetic material Alternatively, the mounting unit 315 and the mounting unit 325 are both components using hard magnetic materials and attract each other. For example, the soft magnetic material can be iron, cobalt, nickel or ferrite, etc.; the hard magnetic material can be alnico permanent magnet alloy, iron chromium cobalt permanent magnet alloy, permanent ferrite, rare earth permanent magnet material or composite Permanent magnet materials, etc.

In some embodiments, the magnetic attraction components in the electronic device 100 may include multiple, so that the electronic device 100 and the external device 200 can be installed together more firmly. Also, the magnetic attraction component in the electronic device 100 may be located outside the wireless coil 312a, so that the influence of the magnetic attraction component on the wireless power transmission efficiency of the wireless coil may be reduced or avoided. Similarly, the magnetic attraction components in the external device 200 may also include multiple and are located outside the wireless coil 322 a of the external device 200 .

In some embodiments, when the mounting component 325 on the external device 200 adopts a hard magnetic material and the mounting component 315 on the electronic device 100 adopts a soft magnetic material, the Hall device in the connection auxiliary unit 314 on the electronic device 100 can be mounted on the Next to the mounting part 315 of the soft magnetic material. The mounting part 325 of the hard magnetic material on the external device 200 can also be the connection auxiliary unit 325 of the external device 200 , and the external device 200 does not need to be provided with a separate connection auxiliary unit 325 .

In some embodiments, in order to facilitate the user to install the electronic device 100 and the external device 200 accurately and quickly, on the outside of the housing on the back of the electronic device 100 and the external device 200, a position corresponding to the installation unit inside the housing may be provided with convenient User-installed prompt information. Exemplarily, a circular mark may be provided on the exterior of the back shell of the electronic device 100 and the external device 200, respectively, and the circular mark corresponds to the magnetic attraction component inside the casing. so that the electronic device 100 and the external device 200 are installed together by magnetic attraction components, so as to align the components such as the short-distance transmission antenna and the wireless coil in the electronic device 100 and the external device 200 .

In some embodiments, one of the electronic device 100 or the external device 200 may be provided with a mounting unit, and the other device may not be provided with a mounting unit. For example, a reusable non-marking glue is provided on the casing on the back of the external device 200 , and the non-marking glue can be used to install the external device 200 and the electronic device 100 together.

When the electronic device 100 is connected to the external device 200, after the mounting unit 315 of the electronic device 100 and the mounting unit 325 of the external device 200 are installed together, there should be no metal space between the wireless coils of the electronic device 100 and the external device 200 that are aligned with each other. Or batteries, chips and other components that include metal to avoid the impact of metal on power transmission. For example, when there is a chip between the two wireless coils, the magnetic energy of the wireless coil will be converted into the thermal energy of the metal on the chip, which will affect the efficiency of the conversion of the magnetic energy emitted by the antenna to electrical energy and the efficiency of wireless power transmission; Cause the chip to heat up and be damaged. If the above situation occurs, the metal spaced between the short-distance transmission antennas may absorb the wireless signal transmitted by the transmitting-end antenna, so that the receiving-end antenna cannot receive the wireless signal.

Moreover, after the electronic device 100 and the external device 200 are fixed together, when the user moves the electronic device 100 , the position of the external device 200 also changes with the change of the position of the electronic device 100 . Alternatively, when the user moves the external device 200 , the position of the electronic device 100 also changes with the change of the position of the external device 200 . Therefore, when the user uses the electronic device 100 or an external device, the wireless power and wireless data transmission will not be affected, and at the same time, the normal operation of the wireless power and wireless data transmission can be ensured.

For example, the mobile phone and the USB flash drive are fixed together by the installation unit. When the user picks up the mobile phone to use it (for example, browse news) and move around at will, the wireless power and wireless data transmission can still be performed normally between the mobile phone and the USB flash drive.

In addition, compared with the external interfaces and connecting wires used for charging or data transmission in the prior art, the electronic device 100 and the external device 200 fixed by the mounting unit 315 and the mounting unit 325 are easily detached, and will not be dragged by the connecting wires. The electronic device 100 or the external device 200 is damaged due to a drag problem.

The battery 316 shown in FIG. 3B can be used to supply power to various components of the electronic device 100 when the electronic device 100 is in operation; to charge the battery 316 itself when the electronic device 100 receives wireless power input from the external device 200 ; When the device 100 transmits wireless power to the external device 200, it provides power to the outside.

It can be understood that the structures illustrated in the embodiments of the present application do not constitute a specific limitation on the electronic device 100 and the external device 200 . In other embodiments of the present application, the electronic device 100 and the external device 200 may include more or less components than those shown, or some components may be combined, or some components may be separated, or different component arrangements. The illustrated components may be implemented in hardware, software, or a combination of software and hardware.

As shown in FIG. 4A , the cylinders on the tops of the electronic device 100 and the external device 200 represent short-range transmission antennas, and the dotted lines with arrows indicate that the polarization direction of the short-range transmission antennas is the vertical direction. For example, a short-range transmission antenna with an upward polarization direction in the electronic device 100 is used for sending wireless data; correspondingly, a short-range transmission antenna with an upward polarization direction in the external device 200 is used for receiving wireless data. Moreover, the short-range transmission antenna whose polarization direction is downward in the electronic device 100 is used for receiving wireless data; correspondingly, the short-range transmission antenna whose polarization direction is downward in the external device 200 is used for sending wireless data.

The polarization direction of the short-distance transmission antenna can also be other directions. 4B, the cylinder on the top of the electronic device 100 and the external device 200 represents the short-range transmission antenna, the dotted line with arrows represents the polarization direction of the short-range transmission antenna is the horizontal direction, the short-range transmission antenna of the electronic device 100 and the external device 200 The polarization directions from the transmission antenna are aligned with each other. For example, the short-range transmission antenna whose polarization direction is rightward in the electronic device 100 is used for sending wireless data; correspondingly, the short-range transmission antenna whose polarization direction is rightward in the external device 200 is used for receiving wireless data. Moreover, the polarization direction of the electronic device 100 is a left short-range transmission antenna for receiving wireless data; correspondingly, the polarization direction of the external device 200 is a left short-range transmission antenna for sending wireless data.

For another example, when the electronic device 100 is a mobile phone and the external device 200 is a panoramic camera, the appearance diagrams of different viewing angles after the mobile phone 501 and the panoramic camera 502 are installed can be seen in FIGS. 5A-5D .

The wireless interaction method provided by the embodiments of the present application will be described below by taking the electronic device 100 having the structure shown in FIG. 3A and FIG. 3B as the mobile phone 100 in the wireless system 10 shown in FIG. 2 as an example.

The mobile phone is mounted with an external device through a mounting unit (such as a magnetic component). The mobile phone can determine information such as the direction of wireless power transmission and wireless data parameters between the mobile phone and the external device according to the currently installed external device (such as a U disk).

The principle of wireless power transmission may include electromagnetic induction, magnetic resonance, or radio waves. Standards for wireless power transfer may include Qi standards, power matters alliance (PMA) standards, alliance for wireless power (A4WP) standards, or Rezence standards, and the like. The embodiments of the present application do not limit the principles and standards used for wireless power transmission. Other wireless power transmission principles or customized wireless power transmission standards can also be used between the mobile phone and the external device. In the following embodiments, the wireless power transmission mode based on the Qi standard and the principle of electromagnetic induction will be used as an example for description.

In some embodiments, the mobile phone may first detect the external device according to the connection auxiliary unit, and determine the power transmission direction with the external device according to the connection auxiliary unit, so as to further complete wireless power transmission with the external device according to the power transmission direction.

For example, the auxiliary connection auxiliary unit on the external device may be an electronic tag, such as an NFC tag, or an RFID tag. The electronic label can include related device information of the external device. Referring to FIG. 6A , the auxiliary connection unit on the mobile phone can be an electronic label scanner, and the mobile phone can detect the electronic label through the auxiliary connection unit, so as to determine that an external device with an electronic label is detected. The mobile phone obtains the content in the electronic label of the external device through the electronic label scanner. Since the electronic tag is in the near field communication mode, when the electronic tag is scanned correctly, it can be understood that there is a good installation state between the devices.

Electronic tag scanners on mobile phones can provide energy to electronic tags in the form of emitting alternating magnetic fields. After the mobile phone and the external device are installed together, the electronic tag scanner on the mobile phone and the electronic tag on the external device can be aligned or approached, so that the induction coil on the electronic tag can receive the energy of the alternating magnetic field and return a response signal, So that the electronic label scanner can receive data to read the information in the electronic label.

Then, referring to FIG. 6A , the mobile phone can determine the wireless interaction parameter according to the content in the electronic tag (ie, the tag information). The wireless interaction parameter includes the wireless power transmission direction, that is, the mobile phone can determine the wireless power transmission direction according to the content in the electronic tag.

The content in the electronic label of the external device may include the power transmission direction when the external device performs wireless power transmission. For example, if the content in the electronic label indicates that the external device is a "power receiver", the mobile phone can determine that the power transmission direction is that the mobile phone transmits wireless power to the external device. For another example, if the content in the electronic label indicates that the external device is a "power transmitter", the mobile phone can determine that the power transmission direction is that the external device transmits wireless power to the mobile phone.

For another example, if the content in the electronic label indicates "the power supply mode is mode 0", the mobile phone can determine that the power transmission direction is that the mobile phone transmits wireless power to the external device. For another example, if the content in the electronic label indicates "the power supply mode is mode 1", the mobile phone can determine that the power transmission direction is that the external device transmits wireless power to the mobile phone.

For another example, the corresponding relationship between the device type of the external device and the power transmission direction is preset on the mobile phone. If the content in the electronic label indicates that the device type of the current device is a U disk, the mobile phone can determine that the power transmission direction is that the mobile phone transmits power to the U disk. If the content in the electronic tag indicates that the device type of the current device is a projector, the mobile phone can determine that the power transmission direction is that the projector transmits power to the mobile phone.

After the mobile phone determines the power transmission direction according to the electronic tag, wireless power transmission can be performed between the mobile phone and the external device according to the power transmission direction. For example, if the user wants to copy some documents, pictures or other data between the mobile phone and the U disk, the mobile phone can be installed with the U disk, and the external device is the U disk. If the mobile phone determines that the power transmission direction is that the mobile phone transmits wireless power to the external device according to the electronic label, referring to FIG. 6A , the mobile phone sets itself to the wireless power transmission mode. Exemplarily, for a schematic diagram of the wireless interaction between the mobile phone 700 and the USB flash drive 701, see FIG. 7 . The mobile phone 700 can transmit wireless power to the USB flash drive 701 to supply power to the USB flash drive 701 .

Then, the phone detects whether there is an external device nearby. If the mobile phone detects that there is an external device nearby, it is further determined whether the external device is a wireless power receiving end device. After the mobile phone detects the external device as the wireless power receiving end, referring to FIG. 6A , establishes a wireless power connection with the external device.

Specifically, based on the Qi standard, the mobile phone as the wireless power transmitter can determine whether the wireless coil of the wireless power receiver is in place according to the change of the parallel resonance point of the wireless coil. If the wireless coil of the mobile phone can detect other wireless coils, the mobile phone can determine that there is an external device nearby. Next, in the Ping step, the mobile phone provides a low-power digital ping communication signal through the wireless coil. The wireless coil of the external device performs data modulation through a switch that adjusts its resistance or capacitance. If the wireless coil of the mobile phone receives the communication data from the wireless coil of the external device, it is determined that the nearby external device is the wireless power receiving end. Otherwise, the external device may be another interfering device and not a target device that can receive wireless power.

After the mobile phone and the external device establish a wireless power connection, the power transmission parameters between the mobile phone and the external device can be determined, so as to perform wireless power transmission according to the power transmission direction and the power transmission parameters. Wherein, the power transmission parameter may include coupling coefficient, signal strength, target power value, maximum power value, maximum power request of the receiving end, or power adjustment request, and the like.

In some embodiments, as shown in FIG. 6A , the wireless interaction parameter includes the power transmission parameter, and the mobile phone can determine the power transmission parameter according to the content in the electronic tag.

In other embodiments, referring to FIG. 6B, the mobile phone may negotiate power transfer parameters with the external device. For example, the mobile phone can send the first wireless information to the external device to request to negotiate power transfer parameters, and the external device can return the second wireless information to the mobile phone to respond to the power transfer parameter negotiation request. It can be understood that, the first wireless information and the second wireless information may include one or more messages, which are not limited in this embodiment of the present application.

Wherein, the first wireless information includes power transmission parameters and/or parameters for determining power transmission parameters. Alternatively, the second wireless information includes power transfer parameters and/or parameters used to determine power transfer parameters.

For example, the power transmission parameter includes a target power value of the mobile phone for wireless power transmission. Exemplarily, the mobile phone sends a plurality of optional power values to the U disk through the first wireless information; the U disk returns the selected target power value to the mobile phone through the second wireless information. The mobile phone provides wireless power to the U disk according to the target power value.

In another example, the mobile phone requests the U disk to obtain the target power value through the first wireless information; the U disk returns the target power value to the mobile phone through the second wireless information. The mobile phone provides wireless power to the U disk according to the target power value.

In another example, the mobile phone requests the U disk to obtain the maximum acceptable power value of the U disk through the first wireless information; the U disk returns the maximum acceptable power value to the mobile phone through the second wireless information. The mobile phone determines the target power value according to the maximum acceptable power value of the U disk, so as to provide wireless power to the U disk according to the target power value.

For another example, the mobile phone can send the available maximum power value to the USB flash drive through the first wireless information, and the USB flash drive can request the power value to be provided from the mobile phone through the second wireless information. If the mobile phone determines that the maximum power value that can be provided is greater than the power value requested by the U disk, the mobile phone determines that the power value of the wireless power transmission is the power value requested by the U disk.

It should be noted that the mutual information in the power transmission parameter negotiation process may be sent through the wireless coil (ie wireless power communication). Through signal modulation, the mutual information can be carried on the wireless magnetic energy signal sent by the wireless coil for transmission. For example, in the Qi protocol, the information of the wireless power receiving end is transmitted to the wireless power transmitting end through the ASK modulation method through the coil, and the wireless power transmitting end sends the information to the wireless power receiving end using the FSK modulation method for transmission. There are specific flag bits in the communication data packet format, which are used to determine the type of the data packet, so as to implement the corresponding response according to the type of the data packet.

In some other embodiments, the wireless interaction parameters may also include power transfer parameters. The mobile phone can determine the power transmission parameters according to the content in the electronic tag. The mobile phone can directly perform wireless power transmission with the external device according to the power transmission parameters provided by the electronic tag; it does not need to negotiate the power transmission parameters, so the processing flow of the wireless power transmission can be simplified, and the wireless power transmission can be established between the mobile phone and the external device as soon as possible. power connection.

In the process of wireless power transmission, when the wireless power receiving end needs to increase or decrease the wireless power (or current), it can also send a power adjustment request to the wireless power transmitting end through the wireless signal sent by the wireless coil to request to adjust the transmitted power. The amount of wireless power. For example, the U disk may require more power during the writing process, so the U disk can send a power adjustment request to the mobile phone through the wireless coil. After receiving the power adjustment request through the wireless coil, the mobile phone adjusts the size of the wireless power transmitted to the U disk.

Referring to FIG. 6A , if the mobile phone determines, according to the content in the electronic tag, that the power transmission direction is that the external device transmits wireless power to the mobile phone, the mobile phone sets itself to the wireless power receiving mode. For example, if the user wants to play files such as movies or PPT on the mobile phone through the pico projector, the mobile phone can be installed with the pico projector, and the external device is the pico projector. Since pico projectors are generally larger than cell phones, and the batteries in pico projectors may also be larger than those in cell phones, pico projectors can transmit wireless power to cell phones. The phone also consumes power when using the pico projector to play files on the phone. Charging the mobile phone through the micro projector can also avoid the problem of insufficient power of the mobile phone after the file is played, so that the mobile phone still has sufficient power to continue to be used by the user after the file is played. An exemplary schematic diagram of the wireless interaction between the mobile phone 700 and the pico projector 702 can be seen in FIG. 7 . Pico projector 702 can transmit wireless power to cell phone 700 to charge and/or power cell phone 702 .

If the mobile phone is a wireless power receiving end, the mobile phone can turn on the relevant modules in the power receiving mode. After the electronic label of the external device is scanned by the mobile phone, if the external device itself is a wireless power transmitter, it can send a power signal to the mobile phone, that is, the above-mentioned ping signal. The ping signal is a low-power energy signal sent by the wireless power transmitter, which is used by the wireless power receiver to receive the signal and respond to it, so as to be perceived by the wireless power transmitter. The mobile phone can determine whether it receives the ping signal sent by the wireless power transmitter. After the mobile phone receives the ping signal, it can receive wireless power according to the power transmission parameters specified by the electronic tag information, and adjust the power in real time through the wireless power communication channel. Moreover, according to the above description, if the mobile phone is a wireless power transmitter, the mobile phone can turn on the relevant modules in the power transmission mode, transmit the wireless power according to the power transmission parameters specified by the electronic tag information, and measure the power through the communication channel of the wireless power. real-time adjustment.

That is to say, in the wireless interaction method provided by the embodiments of the present application, no matter whether the external device is a U disk, a micro projector, or other devices, the mobile phone can automatically determine the power transmission direction with different external devices, so as to adapt to the Wireless power transmission with different external devices is convenient for users and improves user experience.

Referring to FIG. 6A , the wireless interaction parameters may further include wireless data parameters for wireless short-range data transmission. The mobile phone can also determine the wireless data parameters of wireless short-range data transmission according to the content in the electronic tag. After the mobile phone establishes a wireless power connection, it can automatically perform wireless short-range data transmission according to the wireless data parameters, so that the wireless power transmission and wireless data transmission are organically combined, which can be better suitable for scenarios that require simultaneous power interaction and data interaction. .

The wireless short-range data transmission unit can specifically use a low-power, high-transmission rate wireless short-range communication method such as millimeter wave communication or optical communication (such as visible light communication, infrared communication) to automatically perform wireless short-range data transmission and improve data transmission. Privacy, to meet the user's data transmission requirements. Compared with wireless communication protocols such as Wi-Fi or Bluetooth, the communication protocols of wireless short-range communication methods such as millimeter wave communication or visible light communication are simpler, and the communication process is also simpler. Also, millimeter-wave or visible-light communication signals are used less in other fields and therefore suffer less interference.

Wherein, the millimeter wave communication may use an extremely high frequency (extreme high frequency, EHF) frequency band signal for wireless communication, for example, the EHF frequency band may be 30GHz-300GHz, for example, a 60GHz signal may be used for wireless communication.

The wireless data parameters may include one or more of data transmission direction, data type, data transmission speed, data transmission power, data reception power, or channel quality. For example, the data type may include DP, I2C, USB3.0, USB3.2, USB2.0, camera serial interface (CSI), PPS or computer expansion bus standard (peripheral component interconnect express, PCIE) is a one or more of species, etc. This data type can be understood as the actual data format of the wireless data transmission content. Through wireless short-distance communication such as no millimeter wave communication, these data can be directly modulated and transmitted wirelessly; signals of different data types can also be converted into a unified data type for transmission, for example, into USB3.0 or PCIE and other forms.

Among them, due to the high transmission rate of wireless short-distance communication such as millimeter wave communication and the large amount of data that can be transmitted, multiple types of data can be simultaneously transmitted between mobile phones and external devices through wireless short-distance communication, such as USB3 Packed data of .0+USB2.0+I2C+PPS type. In other embodiments, the packaged data can be uniformly converted into a high-speed interface data type, for example, into a PCIE interface data type, and then the data content of the uniform data type can be transmitted based on wireless short-distance communication.

For example, the content in the electronic label includes the device type. The corresponding relationship between the device type and the wireless data parameter is preset on the mobile phone, and the mobile phone can determine the corresponding wireless data parameter according to the device type. Exemplarily, the device type represented by the content in the electronic label is a USB flash drive, the mobile phone determines, according to a preset correspondence, that the data transmission direction corresponding to the USB flash drive is bidirectional transmission, and the data type is a USB type. In another example, the device type represented by the content in the electronic tag is a projector, and the mobile phone determines that the data transmission direction corresponding to the projector according to the preset correspondence relationship is the mobile phone to transmit data to the projector, and the data type can be DP type and I2C type. . In another example, the device type represented by the content in the electronic label is a camera, and the mobile phone determines that the data transmission direction corresponding to the camera according to the preset correspondence is the camera to transmit data to the mobile phone, and the data type may be MIPI CSI type.

For another example, the content in the electronic label includes the data type. Exemplarily, the data type included in the electronic tag is a USB type, and the mobile phone determines that the data transmission direction is bidirectional transmission according to the USB type. In another example, the data type included in the electronic tag is the CSI type, and the mobile phone determines that the data transmission direction is that the mobile phone receives wireless data.

The mobile phone performs corresponding configuration according to the wireless data parameters determined by the electronic tag. For example, if the mobile phone determines that the data types are DP and I2C according to the electronic label, the mobile phone performs corresponding bus configuration according to DP and I2C. Therefore, during wireless data transmission, the mobile phone can package the DP and I2C data, and transmit them through a unified data transmission interface (or format).

It can be understood that after the mobile phone determines the wireless data parameters according to the electronic tag, it can perform corresponding configuration according to the wireless data parameters before establishing the wireless power connection with the external device; or after establishing the wireless power connection with the external device, according to the wireless data The parameters are correspondingly configured, so that the corresponding configuration is used for wireless data transmission subsequently, which is not limited in the embodiment of the present application.

In some other embodiments, after wireless power transmission is performed between the mobile phone and the external device, as an alternative to determining the wireless data parameters according to the electronic tag, the mobile phone can also negotiate with the external device through wireless information to determine the wireless data parameters. parameter. For example, referring to FIG. 6B, the mobile phone can send third wireless information to the external device to request negotiation of wireless data parameters, and the external device can return fourth wireless information to the mobile phone to respond to the power transfer parameter negotiation request. It can be understood that the third wireless information and the fourth wireless information may include one or more messages, which are not limited in this embodiment of the present application.

The third wireless information includes wireless data parameters and/or parameters used to determine wireless data parameters. Alternatively, the fourth wireless information includes wireless data parameters and/or parameters for determining wireless data parameters.

For example, the wireless data parameter includes the data type of wireless data transmission. Exemplarily, the mobile phone side stores the correspondence between the device type and the data type. The mobile phone can send the device type request information to the external device through the first wireless information. The external device may send the device type information of the external device to the mobile phone through the second wireless information. The mobile phone determines the data type of wireless data transmission according to the device type information of the external device, so as to use the data type for wireless data transmission.

For another example, the mobile phone may send the data type request information to the external device through the first wireless information. The external device can reply the data type to the mobile phone through the second wireless information. The mobile phone uses the data type replied by the external device for wireless data transmission.

For another example, the mobile phone may send the device type request information to the external device through the first wireless information. The external device may send the device type information of the external device to the mobile phone through the second wireless information. The mobile phone determines multiple optional data types according to the device type of the external device, and sends the multiple optional data types to the external device through another first wireless message. The external device replies the selected at least one data type to the mobile phone through another second wireless message. The mobile phone performs wireless data transmission according to the data type selected by the external device.

It should be noted that in the existing wireless data transmission methods such as Wi-Fi, the wireless data transmission situation is limited by the influence of the entire network environment, and data parameters are not determined and negotiated in the prior art. Even if both parties of the data transmission determine the data transmission parameters, the data transmission cannot actually be performed according to the determined data transmission parameters. However, in the wireless short-range data transmission method provided by the embodiment of the present application, the mobile phone and the external device are point-to-point data transmission, and the data transmission parameters can be determined and negotiated according to the requirements and the capabilities of both parties, so that the data transmission parameters can be better used according to the data transmission parameters. Perform wireless data transfer.

Then, referring to FIG. 6A and FIG. 6B , the mobile phone establishes a data connection with an external device, thereby performing wireless short-range data transmission.

For example, a mobile phone can establish a data connection with an external device by connecting a detection signal. The data sending unit of the mobile phone sends the detection signal, and the data receiving unit receives the detection signal. In some embodiments, the data receiving unit and the data sending unit of the mobile phone may be in a working state all the time, so as to continuously send and receive connection detection signals. In other embodiments, the data sending unit of the mobile phone wakes up periodically and sends a connection detection signal. When the data receiving unit of the mobile phone receives the detection signal sent by other devices, the mobile phone acts as the device end of data transmission, and the other devices are host devices and act as the host end of data transmission. After the data receiving unit of the mobile phone receives the detection signal sent by other devices, the data transmission unit of the mobile phone sends confirmation information of receiving the detection signal to indicate that the data channel connection is established and wireless data transmission can be performed. When the data receiving unit of the mobile phone receives the detection signal confirmation information sent by other devices, it can represent the connection of the wireless communication data channel and can perform data transmission. At this time, the mobile phone is used as the host side of data transmission, and other devices are peripheral devices (such as cameras, etc.), which are used as the device side of data transmission.

Moreover, after the mobile phone establishes a wireless power connection and turns on the data receiving unit and the data transmitting unit, if the data connection is not established within the preset duration 1, the mobile phone determines that there is no possibility of a data connection, so the data receiving unit and the data transmitting unit can be turned off. .

It should be noted that when the method shown in FIG. 6A is adopted, the mobile phone determines information such as wireless data parameters according to the electronic tag, and can directly perform wireless short-range data transmission according to the determined wireless data parameters; Therefore, the processing flow of data transmission is simpler, and the wireless short-distance data transmission between the mobile phone and the external device can be started faster.

When the method shown in FIG. 6B is adopted, the mobile phone can exchange wireless information with the external device based on the wireless coil to negotiate wireless data parameters, and then establish a wireless data connection. Alternatively, the mobile phone may first establish a wireless data connection with the external device, and then negotiate wireless data parameters with the external device based on the wireless data connection. This embodiment of the present application does not limit the sequence of wireless data parameter negotiation and wireless data connection establishment.

Subsequently, after using the micro projector to play the file, if the user wants to use the panoramic camera to capture images, the mobile phone can be installed with the panoramic camera, and the external device is switched from the micro projector to the panoramic camera. The mobile phone can scan the electronic label in the panoramic camera to determine that the power transmission direction is that the mobile phone transmits wireless power to the panoramic camera, and the panoramic camera transmits data wirelessly to the mobile phone, and the data types are MIPI CSI and I2C types. Exemplarily, the schematic diagram of the wireless interaction between the mobile phone 700 and the panoramic camera 703 can be seen in FIG. 7 . Cell phone 700 may transmit wireless power to panoramic camera 703 to power and/or charge panoramic camera 703 . That is to say, the mobile phone can adaptively switch to transmit wireless power to the panoramic camera and receive wireless data from the panoramic camera; that is, the mobile phone can automatically adapt to the wireless power transmission and wireless data transmission mode between the external device of the panoramic camera.

It can be seen from the above that the mobile phone can adaptively switch the wireless power transmission direction and wireless data parameters according to different external devices in the wireless system, so as to automatically adapt to the wireless power and data transmission requirements between different devices, and transfer the wireless power to the wireless power transmission. The wireless data transmission is organically combined and does not require manual operation by the user.

In the wireless interaction method provided by the embodiment of the present application, wireless power transmission and short-distance wireless data transmission can be performed wirelessly between the mobile phone and the external device. The phone can do away with external interfaces for charging or data transfer. Wireless power transmission and short-distance wireless data transmission can be performed between the mobile phone and the external device after installation through the installation unit, which is more convenient for installation. Therefore, the mobile phone will not cause inconvenience to the user due to the connection line, and the exterior of the mobile phone does not need to be provided with an opening, which can improve the appearance and waterproof performance of the mobile phone.

In some other embodiments, a wireless power connection needs to be established between the mobile phone and the external device first, and then the power transmission direction is determined, and then the wireless power transmission is performed according to the power transmission direction.

For example, the connection auxiliary unit on the mobile phone includes a Hall device, and the connection auxiliary unit on the external device is a magnetic element such as a magnet. The mobile phone defaults to the wireless power receiving end, and the default is the wireless power receiving mode. Among them, compared with the default of the mobile phone as the wireless power transmitter, the default of the wireless power receiver can save the power consumption of the mobile phone.

Referring to Figure 8, when the mobile phone detects that a magnetic element is approaching through the Hall device, it is determined that an external device is detected; at this time, the mobile phone can detect whether it receives wireless power through the wireless coil. If the mobile phone receives wireless power, it is determined that the external device is the wireless power transmitter. Then, the mobile phone establishes a wireless power connection with the external device. In addition, the mobile phone and the external device can negotiate power transmission parameters by exchanging wireless information, so as to perform wireless power transmission according to the power transmission parameters. For the description of related processes such as negotiation of power transmission parameters, reference may be made to the descriptions in the above embodiments, and details are not repeated here.

Specifically, the wireless power receiving unit of the mobile phone can receive the ping signal transmitted from the wireless power transmitter through the wireless coil, and then return a data packet (for example, a data packet of signal strength) to the wireless power transmitter, and then follow the wireless power transmission process. , perform interaction of power transmission parameters, and then transmit wireless power according to the power transmission parameters.

If the mobile phone does not receive wireless power within the preset duration 2, referring to FIG. 8 , the mobile phone switches to the wireless power transmission mode to detect the wireless power receiving end device. If the mobile phone detects an external device serving as a wireless power receiving end device, it establishes a wireless power connection with the external device. In addition, power transmission parameters can be negotiated between the mobile phone and the external device, and wireless power is performed according to the power transmission parameters. The preset duration 2 can be set differently according to factors such as the power consumption of the mobile phone, the hardware detection speed, or the operating system used.

Then, referring to FIG. 8 , the mobile phone can establish a data connection with the external device, and negotiate wireless data parameters with the external device by exchanging wireless information, thereby performing wireless data transmission according to the wireless data parameters.

In some embodiments, the mobile phone may carry interactive information through a wireless coil (eg, the wireless coil may have a communication rate of 2kbps), thereby negotiating wireless data parameters with an external device. For example, the mobile phone can exchange device ID information through the wireless coil, so as to determine the device type of the external device according to the device ID information. For different device types, the corresponding data transmission direction, data type and other wireless data parameters can be determined. The mobile phone turns on the corresponding data receiving unit or data transmitting unit according to the data transmission direction. After the two parties exchange the detection signal and the detection signal confirmation information, the mobile phone establishes a data connection with the external device, and performs wireless data transmission according to the negotiated wireless data parameters.

In other embodiments, the mobile phone and the external device may first establish a data connection by exchanging the detection signal and the detection signal confirmation information. Then, the mobile phone can negotiate wireless data parameters with the external device through the data connection, and perform wireless data transmission according to the negotiated wireless data parameters.

It can be understood that the mobile phone can exchange wireless information with an external device based on the wireless coil to negotiate wireless data parameters, and then establish a wireless data connection. Alternatively, the mobile phone may first establish a wireless data connection with the external device, and then negotiate wireless data parameters with the external device based on the wireless data connection. This embodiment of the present application does not limit the sequence of wireless data parameter negotiation and wireless data connection establishment.

In the scheme using the Hall device, the mobile phone can automatically negotiate information such as the direction of wireless power transmission, power transmission parameters and wireless data parameters with different external devices in the wireless system. Therefore, the mobile phone can automatically adapt to the wireless power and data transmission requirements between different devices according to information such as wireless power transmission direction, power transmission parameters and wireless data parameters, and organically combine wireless power transmission and wireless data transmission, and No manual action by the user is required. Moreover, wireless power transmission and short-distance wireless data transmission can be performed wirelessly between the mobile phone and the external device. Therefore, the external interface for charging or data transmission is eliminated, which is convenient for users to use, and improves the appearance and waterproof performance of the mobile phone.

In some other embodiments, the connection auxiliary unit may be a contact. When the contacts on the outer surface of the mobile phone are in contact with the contacts on the outer surface of the external device, the mobile phone can be triggered to determine the power transmission direction, power transmission parameters, or wireless data parameters and other information, and establish a wireless power connection and a wireless data connection, thereby Perform wireless power transfer and wireless data transfer.

In addition, when the mobile phone determines that the distance between the mobile phone and the external device is relatively long, the communication range between the mobile phone and the external device may have exceeded the communication range of the wireless short-distance communication method, so the above-mentioned wireless power connection and wireless data connection can be disconnected. For example, the electronic tag scanner in the mobile phone can continuously or periodically emit radio frequency energy to form an alternating magnetic field; or, a scanning switch is set on the mobile phone. After the mobile phone detects that the scanning switch is turned on, it can periodically emit radio frequency energy to form an alternating magnetic field. Change the magnetic field; or, when the mobile phone detects that an object is approaching through the distance sensor, the electronic tag scanner is triggered to emit radio frequency energy to form an alternating magnetic field. Among them, the size of the radio frequency energy transmission power can affect the size of the induction area of the alternating magnetic field. The induction coil on the electronic tag in the sensing area can receive the energy of the alternating magnetic field and return a response signal, and the electronic tag scanner in the mobile phone can detect the electronic tag. If the mobile phone or the external device is removed and the electronic tag is moved out of the sensing area, the electronic tag scanner in the mobile phone can no longer scan the electronic tag. If the electronic tag scanner in the mobile phone can no longer scan the electronic tag, or the contacts on the outer surface of the mobile phone are disconnected, or the power transmission state of the wireless coil is unstable, it can indicate that the distance between the mobile phone and the external device may have exceeded. The communication range of the wireless short-range communication method can disconnect the wireless power connection and the wireless data connection.

In some other embodiments, when the external device itself is powered by a battery, the mobile phone may not perform wireless charging with the external device, but only perform wireless data transmission with the external device.

For example, an electronic label scanner is set on a mobile phone, and an electronic label is set on an external device. After the mobile phone and the external device are installed together, the mobile phone can automatically detect the electronic label through the electronic label scanner, so as to determine that the external device is detected. The mobile phone reads the content in the electronic tag, determines wireless data parameters according to the content in the electronic tag, and automatically performs wireless data transmission according to the wireless data parameters.

For another example, the mobile phone is provided with a Hall device, and the external device is provided with a magnetic element. After the mobile phone and the external device are installed together, the mobile phone can automatically detect the magnetic element through the Hall device, so as to determine that the external device is detected. Then, the mobile phone negotiates wireless data parameters with the external device, thereby automatically performing wireless data transmission according to the wireless data parameters.

In some other embodiments, the mobile phone may also be provided with a switch for controlling the direction of power transmission. Exemplarily, referring to FIG. 9A , a switch 901 is provided on the mobile phone, and when the switch 901 is turned on, it means that the mobile phone is wirelessly charged to the outside. Referring to FIG. 9B , if the mobile phone detects that the switch 901 is on, the power transmission direction is that the mobile phone transmits wireless power to the external device. The mobile phone is a wireless power transmitter and is set to the wireless power transmitter mode. Then, the mobile phone can detect whether there is a wireless power receiver nearby, establish a wireless power connection, negotiate power transmission parameters, and perform wireless power transmission. If the mobile phone detects that the user has turned off the switch 901, the power transmission direction is that the mobile phone receives wireless power from an external device, the mobile phone is a wireless power receiving end, and is set to a wireless power receiving mode. Then, the mobile phone can detect whether there is a wireless power transmitter nearby, negotiate power transmission parameters, and establish a wireless power connection with the external device as the wireless power transmitter. After that, similar to the above-mentioned solution using the Hall device, a data connection can be established between the mobile phone and the external device, wireless data parameters can be negotiated, and wireless short-distance data transmission can be performed.

In the solution using the switch shown in FIG. 9A , the mobile phone can determine the wireless power transmission direction according to the switch, and automatically negotiate information such as power transmission parameters and wireless data parameters with different external devices in the wireless system. Therefore, the mobile phone can automatically adapt to the wireless power and data transmission requirements between different devices according to information such as wireless power transmission direction, power transmission parameters and wireless data parameters, and organically combine wireless power transmission and wireless data transmission, and No manual action by the user is required. Moreover, the mobile phone can cancel the external interface for charging or data transmission, which can improve the appearance and waterproof performance of the mobile phone.

In some other embodiments, the mobile phone may be provided with a switch for indicating the wireless power transfer function and/or the wireless data transfer function. Illustratively, referring to FIG. 10 , a switch 1001 and a switch 1002 are provided on the mobile phone. When the switch 1001 is on and the switch 1002 is off, wireless power transmission is performed between the mobile phone and the external device, but wireless data transmission is not performed; when the switch 1001 and the switch 1002 are both on, the mobile phone and the external device are simultaneously connected. Perform wireless power transfer and wireless data transfer.

When the switch 1001 is turned on and the switch 1002 is turned off, in one technical solution, after the mobile phone and the external device establish a wireless power connection, wireless power transmission is performed without establishing a wireless data connection. After detecting that the switch 1002 is turned on, the mobile phone establishes a data connection and performs wireless data transmission.

When the switch 1001 is turned on and the switch 1002 is turned off, in another technical solution, the mobile phone establishes a wireless power connection and a data connection with the external device, and then only performs wireless power transmission without wireless data transmission. After detecting that the switch 1002 is turned on, the mobile phone can quickly perform wireless data transmission directly based on the established data connection.

In some other embodiments, after the mobile phone establishes a wireless power connection and a data connection with an external device, a function setting interface may be displayed to prompt the user whether to select a function. Moreover, depending on the type of the external device, the setting interface displayed by the mobile phone may also be different, and the prompt content to the user by the mobile phone is also different.

Exemplarily, if the external device is a pico projector, after establishing a wireless power connection and a data connection with the external device, the mobile phone can display a function setting interface as shown in FIG. 10 . When the user determines that the power of the pico projector is insufficient, the switch 1001 can be turned off and the switch 1002 can be turned on. At this time, the mobile phone may not receive wireless power from the pico projector, but only wirelessly transmit data to the pico projector.

For another example, if the external device is a pico projector and the power of the pico projector is low, the pico projector can also notify the mobile phone, and the mobile phone can display the setting interface as shown in FIG. Stop receiving charging input from the projector and only do wireless data transfer?". If the mobile phone detects that the user clicks the control 1101, the mobile phone does not receive wireless power from the pico projector, but only transmits data wirelessly to the pico projector.

For another example, if the external device is a panoramic camera, after establishing a wireless power connection and a data connection with the external device, the mobile phone can display a function setting interface as shown in FIG. 11B . When the user determines that the battery of the panoramic camera is insufficient and the mobile phone only needs to transmit wireless power to the panoramic camera without receiving wireless data from the panoramic camera, the user can turn on the switch 1103 and turn off the switch 1102 and the switch 1104 . At this time, the mobile phone can transmit wireless power to the panoramic camera without receiving wireless transmission data from the panoramic camera.

In some other embodiments, referring to FIG. 12 , an embodiment of the present application provides another wireless system 120 , including an electronic device 1201 , a wireless installation device 1202 and an external device 1203 . The electronic device 1201 may have the structural components that the electronic device 100 has as shown in FIG. 3A and FIG. 3B . The wireless installation device 1202 may have the structural components that the external device 200 as shown in FIG. 3B has. The external device 1203 may have a structure as shown in FIG. 3A . For example, the external device 1203 may be a laptop computer or a desktop computer, etc., which are host-type devices with relatively powerful functions.

It can also be understood that, in the wireless system 10 , the wireless installation device is integrated into the external device 200 . In the wireless system 120, the wireless installation device 1202 is not integrated in the external device 1203, and the wireless installation device 1202 and the external device 1203 are two independent devices.

In the wireless system 120, a wired connection is established between the wireless installation device 1202 and the external device 1203, so that high-speed power wired transmission and high-number data wired transmission can be performed.

The electronic device 1201 and the wireless installation device 1202 can be installed together in the same manner as the installation between the electronic device 100 and the external device 200 . Therefore, components such as antennas and wireless coils on the electronic device 1201 and the wireless installation device 1202 can be aligned, so that wireless power transmission and wireless data transmission can be performed between the electronic device 1201 and the wireless installation device 1202 . That is to say, the wireless installation device 1202 is equivalent to a base device or an intermediary device for fixing the electronic device 1201 .

Exemplarily, the perspective effect of the electronic device 1201 and the wireless installation device 1202 about to be installed together, and the schematic diagram of the effect after the wireless installation device 1202 and the external device 1203 are wiredly connected can be seen in FIG. 13A . The perspective view of the electronic device 1201 and the wireless installation device 1202 after being installed together can be seen in Figure 13B. The electronic device 1201 and the wireless installation device 1202 are installed together, and the appearance schematic diagram after the wireless installation device 1202 and the external device 1203 are wiredly connected can be seen in FIG. 13C . For example, if the user wants to copy some data between a mobile phone and a laptop, the electronic device 1201 can be a mobile phone, the external device 1203 can be a laptop, the mobile phone can be installed with the wireless installation device, and the wireless installation device can be installed with the laptop Computer wired connection.

In the same manner as the wireless power transmission and wireless data transmission between the external device 200 and the electronic device 100 , wireless power transmission and wireless data transmission can be performed between the wireless installation device 1202 and the electronic device 1201 . Therefore, wireless power transmission and wireless data transmission can be performed between the electronic device 1201 and the external device 1203 through the wireless installation device 1202 .

It should be noted that since the wireless installation device 1202 is equivalent to an intermediary device, when the electronic device 1201 and the wireless installation device 1202 adopt the electronic label solution, the wireless power transmission direction in the electronic label of the wireless installation device 1202, the wireless power transmission The parameters, or wireless interaction parameters such as wireless data parameters, can be acquired from the external device 1203 through a wired connection with the external device 1203 . That is to say, the external device 1203 can transmit the wireless interaction parameters to the wireless installation device 1202 through a wired connection with the wireless installation device 1202 . The wireless installation device 1202 stores the wireless interaction parameters in the electronic tag. For example, the external device 1203 may transmit the wireless interaction parameters to the wireless installation device 1202 after establishing a wired connection with the wireless installation device 1202 . In this way, the wireless interaction parameters between the electronic device 1201 and the wireless installation device 1202 can be understood as the wireless interaction parameters for the interaction between the electronic device 1201 and the external device 1203 through the wireless installation device 1202 . Exemplarily, for the interaction flow between the electronic device 1201, the wireless installation device 1202, and the external device 1203, reference may be made to FIG. 14A.

In other embodiments, the external device 1203 is usually a host device, so the power transmission direction is usually that the external device 1203 transmits wireless power to the electronic device 1201 through the wireless installation device 1202 . Therefore, when the electronic device 1201 and the wireless installation device 1202 adopt the electronic label scheme, referring to FIG. 14B , the power transmission direction indicated in the electronic label of the wireless installation device 1202 is that the wireless installation device 1202 transmits wireless power to the electronic device 1201 . After the electronic device 1201 scans the wireless installation device 1202 through the electronic tag, the electronic device 1201 can negotiate information with the wireless installation device 1202 wirelessly, and the wireless installation device 1202 can negotiate information with the external device 1203 through a wired connection, so that the electronic Interaction parameters such as power transmission parameters and wireless data parameters can be negotiated between the device 1201 and the external device 1203 through the wireless installation device 1202 . The power transmission parameters and wireless data parameters are wireless interaction parameters between the electronic device 1201 and the wireless installation device 1202 .

It should also be noted that in the case where the electronic device 1201 and the wireless installation device 1202 adopt solutions such as Hall devices or switches, the electronic device 1201 and the wireless installation device 1202 need to negotiate the direction of wireless power transmission, wireless power transmission parameters or wireless Wireless interaction parameters such as data parameters. The wireless interaction parameters negotiated between the electronic device 1201 and the wireless installation device 1202 may be understood as wireless interaction parameters for the electronic device 1201 and the external device 1203 to interact through the wireless installation device 1202 .

In some embodiments, the electronic device 1201 can negotiate information with the wireless installation device 1202 wirelessly, and the wireless installation device 1202 can negotiate information with the external device 1203 through a wired connection, so that the electronic device 1201 and the external device 1203 can exchange negotiation information between the electronic device 1201 and the external device 1203. Wireless interaction parameters are negotiated by wireless installation device 1202 . The wireless interaction parameter is the wireless interaction parameter between the electronic device 1201 and the wireless installation device 1202 . Exemplarily, when the electronic device 1201 and the wireless installation device 1202 adopt the Hall device solution, the interaction flow between the electronic device 1201 , the wireless installation device 1202 and the external device 1203 can be seen in FIG. 15 .

In other embodiments, after the wireless installation device 1202 establishes a wired connection with the external device 1203, the external device 1203 transmits the wireless interaction parameters to the wireless installation device. The wireless installation device 1202 saves the interaction parameters obtained from the external device 1203 . The wireless installation device 1202 negotiates with the electronic device 1201 according to the stored wireless interaction parameters. Exemplarily, when the electronic device 1201 and the wireless installation device 1202 adopt the Hall device solution, the interaction flow between the electronic device 1201 , the wireless installation device 1202 and the external device 1203 can be seen in FIG. 16 .
