Referring to fig. 3, an architecture of an electronic system according to an embodiment of the present application is shown;
the electronic system comprises a charging device and an electronic device for receiving electromagnetic radiation of the charging device to realize charging, wherein:
the charging device includes a communication module 32, a control circuit 33, and a transmitting coil 31.
The transmitting coil 31 is used for wirelessly charging the electronic device. Specifically, the transmitting coil 31 may be designed according to different wireless charging standards, for example, the diameter of the copper wire in the coil, the number of turns of the winding, and the like are adjusted to meet the wireless charging standard of the charging device.
The communication module 32 is configured to obtain device information of the electronic device.
The device information may be information such as a device serial number, a model number, or a wireless charging standard identifier of the electronic device, and is used to determine a wireless charging standard that can be supported by the electronic device.
In some embodiments, the communication module 32 may be a module that can perform signal communication with an electronic device, such as WIFI, bluetooth, infrared communication, NFC, or the like. The communication module 32 may include the communication circuit 1324 of the embodiment of fig. 2.
The device information of the electronic device may be actively sent to the charging device by the electronic device, or acquired from the electronic device by the charging device. The charging device may obtain device information from the electronic device according to a preset trigger mechanism. For example, the distance to the electronic device is detected through signal strength or other means, and when the electronic device approaches the charging device, the electronic device is triggered to acquire device information. Of course, there are many ways to obtain the device information, and the specific obtaining way may be determined according to the actual situation.
The control circuit 33 is electrically connected to the transmitting coil 31 and the communication module 32, and can implement at least two charging modes.
In particular, the control circuit 33 may include a storage and processing circuit, such as the storage and processing circuit 131 in the embodiment of fig. 2. The control circuit 33 is connected to the communication module 32 and the transmitting coil 31 to control the communication module 32 and the transmitting coil 31 to operate.
In some embodiments, the control circuit 33 may include a matching circuit that implements at least two charging modes, and may switch between different charging modes to accommodate different wireless charging standards.
In some embodiments, the control circuit 33 may be configured to: acquiring equipment information of the electronic equipment; determining a target charging mode matched with the electronic equipment according to the equipment information; the electronic device is wirelessly charged based on the target charging mode.
The control circuit 33 can be obtained from the communication module 32 to the electronic device.
As shown in fig. 3, the charging device includes a control module, a transmitting coil 31, and a communication module 32; the electronic device includes the communication module 32 and the receiving coil 35, and may further include other processing circuits, such as a processor, a memory, and a matching circuit.
For example, if the communication module 32 of the charging device is the NFC communication module 32, the charging device may be connected to the NFC communication module 32 in the electronic device through the NFC communication module 32.
After the communication module 32 of the charging device is connected to the communication module 34 of the electronic device, the communication module 32 of the charging device sends a device information obtaining request to the electronic device. After receiving the obtaining request, the communication module 34 of the electronic device may return its own device information to the charging device based on the request.
The device information of the electronic device may include a device model. It is assumed here that the device model of the electronic device included in the device information is device a.
In some embodiments, the target charging mode matched with the electronic device is determined according to the device information, and after the control module acquires the device information, the wireless charging standard which can be supported by the electronic device is determined according to information such as a device serial number, a model number, or a wireless charging standard identifier in the device information.
For example, if the charging device obtains that the device model of the electronic device is device a, it can be known through a preset mapping relationship that the charging mode supported by the device a is the charging mode a. After the charging device determines the wireless charging standard, if the charging device can support the charging mode a and the charging mode B, the control circuit 33 may switch the matching circuit to the matching circuit associated with the charging mode a according to the table lookup result.
After the control circuit 33 of the charging device switches to the matching circuit associated with the charging mode a, the electronic device may be wirelessly charged based on the charging mode a. Specifically, the control circuit 33 feeds power to the transmitting coil 31 according to the signal standard of the charging mode a, the transmitting coil 31 generates a radio frequency field based on the signal standard, and the radio frequency field and the receiving coil 35 of the electronic device form a magnetic induction effect or a magnetic resonance effect, so that wireless power transmission for the electronic device is realized.
As can be seen from the above, the charging device acquires the device information of the electronic device by using the communication module 32, and then adjusts the charging mode of the charging device according to the acquired device information, thereby implementing compatibility with multiple charging standards on the same charging device.
In some embodiments, the control circuit 33 may be used to implement the following functions: detecting whether the electronic equipment is located at a preset position; if yes, establishing connection communication between the communication module 32 and the electronic equipment; device information of the electronic device is acquired from the electronic device.
In some embodiments, the predetermined position may be a position area of an effective working range of the communication module 32. For example, if the preset position is located within 5cm of the communication module 32, it may be determined whether the electronic device is located within 5cm of the communication module 32. In other embodiments, the preset position may also be a position where a distance between the charging device and the electronic device meets a preset condition.
The method for detecting whether the electronic device is located at the preset position may be that the charging device detects a distance from the electronic device through a distance sensor, such as an infrared distance sensor, a pressure sensor, and the like; the distance between the charging device and the electronic device can also be judged by detecting the signal intensity or the magnetic field intensity of a signal sent by the electronic device.
When the electronic device is detected to be located at the preset position, the connection communication between the communication module 32 and the electronic device is established, and the device information of the electronic device is acquired from the electronic device.
In some embodiments, the setting of the preset position may be determined in combination with the effective working distance of the transmitting coil 31, for example, the distance between the preset position and the transmitting coil 31 of the charging device is less than or equal to the effective wireless charging distance between the transmitting coil 31 and the electronic device.
For example, if the effective wireless charging distance between the transmitting coil 31 and the electronic device is 10cm, the preset position may be set to be less than or equal to 10cm from the transmitting coil 31.
In some embodiments, if the electronic device is not detected in the preset position, the electronic device may be considered not to be in the vicinity of the charging device, and there is no need for wireless charging, so that the charging device may be turned off, and the electronic device may be turned on only when the electronic device is detected in the preset position, so as to save electric energy.
Through setting up preset position, battery charging outfit can confirm whether electronic equipment is in effectual communication range, and then carries out wireless connection with electronic equipment to conveniently acquire electronic equipment's equipment information through wireless connection.
In some embodiments, the communication module 32 is a short-range wireless communication module 32, and the short-range wireless communication module 32 may be an NFC communication module 32. The short-range wireless communication module 32 may be configured to detect the presence of a radio frequency field generated by the electronic device to determine whether the electronic device is located at a predetermined location. Wherein, whether the radio frequency field generated by the electronic equipment exists or not is detected, and the detection can be determined by the magnetic induction intensity generated by the radio frequency field.
In some embodiments, the short-range wireless communication module 32 includes a communication coil having a center position coinciding with the center position of the transmitting coil 31.
With reference to fig. 4, a cross-sectional structure of a charging device 40 provided in an embodiment of the present application is shown.
The charging device 40 includes a panel 41, a transmitting coil 42, and a communication coil 43. The panel 41 may be a part of the housing of the charging device 40 and may be used to house an electronic device.
The transmitting coil 42 is used for transmitting a radio frequency field for wireless charging of the electronic device, and the communication coil 43 is used for transmitting or receiving a radio frequency field for short-range wireless communication. Wherein the transmitting coil 42 operates at a relatively low frequency, such as 100kHz-250kHz, and the communication coil 43 operates at a relatively high frequency, such as 13.56 MHz. Of course, the specific operating frequency may be determined according to actual conditions.
The transmitting coil 42 and the communication coil 43 are both annular structures including an axis, the transmitting coil 42 is located at one side of the communication coil 43, and the axis of the communication coil 43 coincides with the axis of the transmitting coil 42, so that the center of the radio frequency field generated by the transmitting coil 42 also coincides with the center of the radio frequency field of the communication coil 43.
Because the working distance of the communication coil 43 in the NFC communication module is generally about 0-10cm, and may only be about 0-5cm in practical application, the NFC communication module of the charging device 40 needs to be close to the NFC communication module of the electronic device to complete connection. Similarly, the effective working distance of wireless charging is generally only about 0-10 cm.
In practical application, wireless charging requires strict alignment to achieve a good charging effect. In order to improve the alignment efficiency of wireless charging, the axis position of the communication coil 43 is overlapped with the axis position of the transmitting coil 42, so that after the NFC communication module of the charging device 40 is connected with the NFC communication module of the electronic device, the transmitting coil 42 of the charging device 40 can be aligned with the receiving coil 42 of the electronic device at the same time, and the connection function of NFC is utilized to realize auxiliary alignment, so that the alignment efficiency of wireless charging can be improved.
In some cases, the charging device 40 may perform wireless charging on the electronic device after the NFC communication module establishes connection, so as to ensure that the charging efficiency of the wireless charging is at a better level.
Referring to fig. 5, a connection structure between the control circuit and the transmitting coil according to an embodiment of the present application is shown.
As shown in fig. 5, the control circuit includes a first matching circuit 331, a second matching circuit 332, and a control switch 333, wherein the first matching circuit 331 and the second matching circuit 332 are both connected to one end of the control switch 333, and the other end of the control switch 333 is connected to the transmitting coil 31, so that the transmitting coil 31 can be controlled to be connected to the first matching circuit 331 or the second matching circuit 332 by controlling the switch 333.
In some embodiments, the control switch 333 may be controlled to switch the connection between the first matching circuit 331 and the transmission coil 31 and between the second matching circuit 332 and the transmission coil 31 according to the target charging mode, so as to realize the switching of the charging mode.
The first matching circuit 331 and the second matching circuit 332 may include circuit components such as a radio frequency transceiver control circuit, a resonant circuit, a power amplifier circuit, a low noise amplifier, a switch, and a filter that are matched with different wireless charging standards, and further cooperate with the transmitting coil 31 to implement different charging modes.
For example, the first matching circuit 331 may implement wireless charging of the electronic device in the charging mode a with the transmitting coil 31, the second matching circuit 332 may implement wireless charging of the electronic device in the charging mode B with the transmitting coil 31, and the control switch 333 is a single-pole double-throw switch.
When the acquired device information determines that the electronic device is adapted to the wireless charging standard of the charging mode a, it may be determined that the target charging mode is the charging mode a, and the control circuit may control the control switch 333 to conduct the first matching circuit 331 and the transmitting coil 31 at this time, so as to implement the charging mode a through cooperation of the first matching circuit 331 and the transmitting coil 31.
It can be understood that, according to different target charging modes, the control circuit may control the control switch 333 to switch between different matching circuits, so that the charging device adapts to different charging modes, and better adapts to electronic devices with different wireless standards.
Of course, in addition to the above-described hardware configuration, the switching between different matching circuits may be realized by software switching or by a separate switch.
Referring to fig. 6, an implementation flow of a wireless charging control method according to an embodiment of the present application is shown in the figure.

The charging device may obtain device information from the electronic device according to a preset trigger mechanism. For example, the distance to the electronic device is detected through signal strength or other means, and when the electronic device approaches the charging device, the electronic device is triggered to acquire device information. Of course, there are many ways to obtain the device information, and the specific obtaining way may be determined according to the actual situation.
In some embodiments, the electronic device may be obtained from the electronic device through the communication module.
For example, if the communication module of the charging device is an NFC communication module, the charging device may be connected to an NFC communication module in the electronic device through the NFC communication module.
After the communication module of the charging device is connected with the communication module of the electronic device, the communication module of the charging device sends a device information acquisition request to the electronic device. After receiving the acquisition request, the communication module of the electronic device may return device information of itself to the charging device based on the request.
