Description
Technical Field
[0001] This application relates to the field of wireless power supply technology, and more particularly to an electronic device powered by electromagnetic waves. Background Technology
[0002] Long-range wireless power supply technology uses electromagnetic waves as a medium for long-distance energy transmission. The power supply device needs to send electromagnetic waves to the electronic device to transmit energy. To improve the power output of long-range wireless power supply, the electronic device needs to send a location signal to the power supply device. The power supply device, upon receiving the location signal, then sends directional electromagnetic waves back to the electronic device. However, the electronic device requires a battery or external power source to send the location signal. When the electronic device lacks power, it cannot send a location signal, thus affecting the power supply device's ability to send directional electromagnetic waves to the electronic device.
[0003] Therefore, how to achieve long-distance wireless power supply when electronic devices lack power is an urgent problem to be solved. Summary of the Invention
[0004] This application provides an electronic device powered by electromagnetic waves, which can achieve accurate positioning and efficient power supply to the electronic device when it is low on power or without a battery.
[0005] In a first aspect, embodiments of this application provide an electronic device powered by electromagnetic waves, characterized in that it includes a wireless power supply module, a positioning module, and a load module. The electronic device operates in two modes: a positioning mode and a power supply mode. The wireless power supply module is used to convert electromagnetic waves and supply power to at least one of the positioning module or the load module. When the electronic device operates in the positioning mode, the wireless power supply module supplies power to the positioning module; when the electronic device operates in the power supply mode, the wireless power supply module supplies power to the load module. The positioning module is used to transmit a positioning signal, which indicates the location of the electronic device.
[0006] As mentioned above, long-range wireless power supply requires the power supply device to confirm the location of the electronic device before it can perform directional power transfer, thus ensuring effective wireless power supply. However, existing technologies such as Bluetooth positioning and UWB positioning often require the electronic device to have a certain amount of power to maintain the normal operation of the chips related to these positioning technologies. Therefore, when the electronic device is depleted or has no battery, these positioning technologies cannot be implemented, and consequently, wireless power supply to the electronic device is also impossible.
[0007] In this embodiment, the operating mode of the electronic device may include a positioning mode and a power supply mode. After receiving electromagnetic waves emitted by the power supply device, the electronic device can convert them into direct current (DC) to power the positioning module or load module within it. In positioning mode, the DC power is input to the positioning module in the electronic device to drive it to emit a positioning signal; in power supply mode, the DC power is input to the load module in the electronic device to power it, enabling the electronic device to operate normally. For example, the load module includes a battery, controller, display screen, communication system, etc. It should be noted that the positioning signal is used to indicate the location of the electronic device. The power supply device can locate the electronic device based on the positioning signal and then directionally emit high-power electromagnetic waves to the electronic device to achieve efficient and stable power supply to the load module within it. Thus, this embodiment optimizes the electronic device, enabling it to receive electromagnetic waves emitted by the power supply device and switch between different operating modes. This allows the power supply device to accurately locate the electronic device and provide efficient and stable wireless power even when the electronic device is low on power or has no battery. Thus, the embodiments of this application greatly expand the application scenarios of wireless power supply, solve the limitations of wireless power supply in the case of passive electronic devices, and meet the actual needs of users.
[0008] In one possible implementation, the load module includes an energy storage module and a functional module, and the power supply mode includes a charging mode and a working mode; wherein, when the electronic device is operating in the charging mode, the wireless power supply module supplies power to the energy storage module; and when the electronic device is operating in the working mode, the wireless power supply module supplies power to the functional module.
[0009] In this embodiment, the load module in the electronic device may include a functional module and an energy storage module. Therefore, based on the different power supply objects in the load, the power supply mode can be further subdivided into a charging mode and a working mode to supply power to the functional module and the energy storage module in the load, respectively, thereby achieving more flexible and efficient wireless power supply and meeting different user needs. Furthermore, in some possible embodiments, if the power supply is sufficient and the energy storage module's power is low, it can also supply power to both the functional module and the energy storage module in the load during the charging or working mode. It should be noted that users can also customize the charging mode or the all-around mode as the default power supply mode according to actual needs, and users can also manually switch modes during power supply, etc. This embodiment does not specifically limit these aspects.
[0010] In one possible implementation, the electronic device operates in either the positioning mode or the power supply mode in response to changes in the power output of the wireless power supply module.
[0011] In this embodiment, the electronic device can switch between different operating modes based on changes in the power output of the wireless power supply module, thereby powering the positioning module or the load module. Specifically, when the wireless power supply module powers the positioning module, it can drive the positioning module to transmit a positioning signal, enabling accurate positioning of the electronic device even when it is low on power or has no battery, thus achieving efficient power supply to the subsequent load module.
[0012] In one possible implementation, in response to a comparison between the power output of the wireless power supply module and a first preset value, the electronic device operates in the positioning mode or the power supply mode.
[0013] In this embodiment, different operating modes can be switched based on the comparison between the power supply power and a first preset value, thereby achieving accurate positioning and efficient power supply for the electronic device. It is understood that before the power supply device completes positioning of the electronic device, the electromagnetic waves emitted by the power supply device are non-directional. At this time, the electromagnetic waves received by the electronic device are weak, and correspondingly, the power supply power output by the wireless power supply module in the electronic device is also relatively small. However, after the power supply device completes positioning of the electronic device, it can emit directional electromagnetic waves towards the electronic device. At this time, the electromagnetic waves received by the electronic device are stronger, and correspondingly, the power supply power output by the wireless power supply module is larger. Therefore, for example, when the power supply power output by the wireless power supply module is less than the first preset value, the electronic device can operate in positioning mode; when the power supply power output by the wireless power supply module is greater than the first preset value, the electronic device can operate in power supply mode.
[0014] In one possible implementation, in response to a comparison between the power output of the wireless power supply module and a second preset value, the electronic device operates in the charging mode or the working mode.
[0015] In this embodiment, the power output of the wireless power supply module can be compared with a second preset value to supply power to different objects in the load module, thereby achieving more flexible and efficient power supply and meeting the actual needs of users. For example, when the power output is much greater than the second preset value, the wireless power supply module can also supply power to the energy storage module and the functional module in the load simultaneously, thus making full use of the energy transmitted by the power supply equipment for comprehensive and efficient power supply.
[0016] In one possible implementation, the electronic device operates in either the charging mode or the operating mode in response to a change in the state of the load module.
[0017] In this embodiment, the power supply can also be tailored to different objects within the load based on the current state changes of the load module, thereby achieving more flexible and efficient power supply to meet the actual needs of users. The state of the load module may include, for example, the power status of the energy storage module and the power consumption status of the functional modules. For instance, when the energy storage module's power level is below 20%, the electronic device can operate in charging mode to power the energy storage module, while when the energy storage module's power level is above 20%, the electronic device can operate in working mode to power the functional modules. As another example, when a user is playing high-definition video or gaming, if the power consumption of the functional modules exceeds a threshold, the electronic device can operate in working mode to power the functional modules.
[0018] In one possible implementation, the electronic device further includes a switching module; in response to a change in the power output of the wireless power supply module, the switching module activates the connection between the wireless power supply module and the positioning module or activates the connection between the wireless power supply module and the load module.
[0019] In this embodiment, the internal structure of the electronic device has been optimized, especially by adding a switch module. In response to changes in the power output of the wireless power supply module, the switch module can be used to connect the wireless power supply module and the positioning module or load module, thereby using the received electromagnetic waves to supply power to the positioning module or load. This achieves effective positioning and wireless power supply in the passive state of the electronic device, avoiding the problem of low efficiency in wireless power supply caused by the inability to achieve positioning in the passive state of the electronic device.
[0020] In one possible implementation, in response to a comparison between the power output of the wireless power supply module and a first preset value, the switch module connects the wireless power supply module and the positioning module or connects the wireless power supply module and the load module.
[0021] In the embodiments of this application, as described above, based on the comparison result between the power supply and the first preset value, the switch module can connect the wireless power supply module and the positioning module, or connect the wireless power supply module and the load module, thereby using the received electromagnetic waves to supply power to the positioning module or the load, so as to achieve accurate positioning and efficient power supply to the electronic device.
[0022] In one possible implementation, in response to a comparison between the power output of the wireless power supply module and a second preset value, the switching module connects the wireless power supply module and the energy storage module or connects the wireless power supply module and the functional module.
[0023] In the embodiments of this application, as described above, based on the comparison between the power supply and the second preset value, the switch module can further connect the wireless power supply module and the energy storage module, or connect the wireless power supply module and the functional module, so as to realize the power supply to different objects in the load module and meet the flexible and efficient power supply requirements.
[0024] In one possible implementation, in response to a change in the state of the load module, the switch module connects the wireless power supply module and the energy storage module or connects the wireless power supply module and the functional module.
[0025] In the embodiments of this application, as described above, based on the state changes of the load module, the switch module can further connect the wireless power supply module and the energy storage module, or connect the wireless power supply module and the functional module, so as to realize the power supply to different objects in the load module and meet the flexible and efficient power supply requirements.
[0026] In one possible implementation, the state changes of the load module include one or more of the changes in the power level of the energy storage module and the changes in the power consumption level of the functional module.
[0027] In this embodiment, power can also be supplied to different objects in the load by combining the current state changes of the load module, thereby achieving more flexible and efficient power supply and meeting the actual needs of users. The state of the load module may include, for example, the power status of the energy storage module and the power consumption status of the functional modules, etc., which will not be elaborated here.
[0028] In one possible implementation, the functional module includes a communication module; the communication module is configured to transmit communication signals when the electronic device is operating in the power supply mode, the communication signals indicating one or more of the power supply power of the wireless power supply module, the power of the energy storage module, and the power consumption level of the functional module.
[0029] In this embodiment, the functional module may include a communication module. In power supply mode, the communication module can transmit communication signals to the power supply device. These signals can indicate the power output of the wireless power supply module, the charge level of the energy storage module, and the power consumption level of the functional module. Upon receiving the communication signal, the power supply device can adjust the corresponding parameters of the emitted electromagnetic waves in real time, thereby ensuring the reliability and efficiency of wireless power supply at all times. For example, the parameters of the electromagnetic waves may include frequency, power, and direction. For example, before the energy storage module's charge reaches 30%, the power supply device can continuously emit high-power electromagnetic waves to achieve rapid charging of the energy storage module. When the energy storage module's charge has reached 85%, the power supply device can appropriately reduce the power of the electromagnetic waves, and so on, which will not be elaborated further here.
[0030] Secondly, embodiments of this application provide a method for powering an electronic device using electromagnetic waves. The electronic device includes a wireless power supply module, a positioning module, and a load module. The electronic device operates in two modes: a positioning mode and a power supply mode. The method includes: converting electromagnetic waves through the wireless power supply module and supplying power to at least one of the positioning module or the load module; supplying power to the positioning module through the wireless power supply module when the electronic device operates in the positioning mode; supplying power to the load module through the wireless power supply module when the electronic device operates in the power supply mode; and transmitting a positioning signal through the positioning module, the positioning signal indicating the location of the electronic device.

In response to changes in the power output of the wireless power supply module, the switch module controls one of the multiplexers to be turned on.
[0033] In one possible implementation, the load module includes an energy storage module and a functional module, and the power supply mode includes a charging mode and an operating mode; one of the multiplexers is connected between the wireless power supply module and the energy storage module, and the other of the multiplexers is connected between the wireless power supply module and the functional module; in response to one or more of the following: a change in the power output of the wireless power supply module, a change in the state of the energy storage module, or a change in the state of the functional module, the switch module controls the conduction of one or more of the multiplexers.

[0056] The embodiments of this application will now be described with reference to the accompanying drawings.
[0057] The terms "first" and "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or apparatuses. It should be noted that when an element is referred to as being "coupled" or "connected" to one or more other elements, it can be a direct connection of one element to the other one or more elements, or an indirect connection.
[0058] It should be understood that in this application, "at least one (item)" means one or more, and "more than" means two or more. "And / or" is used to describe the relationship between related objects, indicating that three relationships can exist. For example, "A and / or B" can represent three cases: only A exists, only B exists, and both A and B exist simultaneously, where A and B can be singular or plural. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship. "At least one (item) of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one (item) of a, b, or c can represent: a, b, c, "a and b", "a and c", "b and c", or "a and b and c", where a, b, and c can be single or multiple.
[0059] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will understand, explicitly and implicitly, that the embodiments described herein can be combined with other embodiments.
[0060] The terms “component,” “module,” “system,” etc., used in this specification are used to refer to computer-related entities, hardware, firmware, combinations of hardware and software, software, or software in execution. For example, a component can be, but is not limited to, a process running on a processor, a processor, an object, an executable file, an execution thread, a program, and / or a computer. As illustrated, both an application running on a processor and the processor itself can be components. One or more components may reside in a process and / or an execution thread, and components may be located on a single computer and / or distributed among two or more computers. Furthermore, these components can be executed from various computer-readable media on which various data structures are stored. Components can communicate, for example, via local and / or remote processes based on signals having one or more data packets (e.g., data from two components interacting with another component between a local system, a distributed system, and / or a network, such as the Internet interacting with other systems via signals).
[0061] First, some of the terms used in this application will be explained to facilitate understanding by those skilled in the art.
[0062] Long-range wireless power supply: The power supply device emits electromagnetic waves, which are received by electronic devices and converted into direct current (DC), thus transferring electrical energy. The power supply device typically includes a radio frequency (RF) front-end circuit for signal generation and control, and a transmitting antenna. The electronic devices typically include a receiving antenna, an energy conversion module, and a control circuit module. The overall efficiency of the wireless charging system mainly depends on the direct current (DC) to radio frequency (RF) energy conversion efficiency, RF to RF spatial transmission efficiency, and RF to DC energy conversion efficiency, which will not be elaborated upon here.
[0063] First, to facilitate understanding of the embodiments of this application, the specific technical problem to be solved by this application is further analyzed and proposed. As mentioned above, to improve the power supply of long-distance wireless power supply, the power supply device needs to first confirm the location of the electronic device before sending directional electromagnetic waves to the electronic device. In the prior art, electronic devices can generally transmit positioning signals through Bluetooth positioning technology or ultra-wideband (UWB) communication technology to enable the power supply device to locate the electronic device. However, when the electronic device is low on power, has no pre-installed battery, or has no external power supply, the Bluetooth chip or ultra-wideband (UWB) chip inside the electronic device cannot operate normally, causing the electronic device to be unable to transmit positioning signals. As a result, the power supply device cannot locate the electronic device, which seriously affects the efficiency of subsequent wireless power supply, or even makes wireless power supply impossible.
[0064] Figure 1 This is a schematic diagram illustrating an application scenario of long-range wireless power supply technology provided in an embodiment of this application. For example... Figure 1 As shown, the power supply device 100 can wirelessly supply power over a long distance to one or more of electronic devices 200a, 200b, 200c, or 200d by emitting electromagnetic waves.
[0065] Electronic devices 200a, 200b, and 200c are equipped with batteries. For example, electronic device 200a is a smartphone, electronic device 200b is a tablet computer, and electronic device 200c is an electric vehicle. In this embodiment, electronic devices 200a, 200b, or 200c can also be smart wearable devices, laptops, electric vehicles, etc. When the battery power in electronic devices 200a, 200b, or 200c is insufficient or malfunctions, they cannot send positioning signals to the power supply device 100, thereby affecting the power supply device 100's ability to send directional electromagnetic waves to electronic devices 200a, 200b, or 200c.
[0066] The electronic device 200d does not have a battery installed. For example, the electronic device 200d is a desktop computer. In this embodiment, the electronic device 200d can also be a radio frequency identification (RFID) card, an electronic toll collection (ETC) vehicle-mounted device, etc. When the electronic device 200d is not powered by an external power source, it cannot send a positioning signal to the power supply device 100, thus affecting the power supply device 100's ability to send directional electromagnetic waves to the electronic device 200d.
[0067] Therefore, in order to solve the problem that current power supply technology does not meet actual needs, this application provides an electronic device powered by electromagnetic waves, which can send a positioning signal to the power supply device in a passive state, so that the power supply device can obtain the location information of the electronic device and then send directional electromagnetic waves to the electronic device.
[0068] Figure 2 This is a schematic diagram of the structure of an electronic device provided in an embodiment of this application. The technical solution of this embodiment can be... Figure 2 The example is implemented in the structure shown or a similar structure. Electronic device 10 can be as described above. Figure 1 Any one of the electronic devices 200a, 200b, 200c, and 200d shown. Figure 2 As shown, the electronic device 10 includes a wireless power supply module 101, a positioning module 102, and a load module 103.
[0069] The wireless power supply module 101 is used to receive electromagnetic waves emitted by the power supply device and convert the electromagnetic waves to power at least one of the positioning module 102 and the load module 103. In one embodiment, the wireless power supply module 101 can convert the electromagnetic waves into corresponding direct current and output the direct current to at least one of the positioning module 102 and the load module 103.
[0070] The positioning module 102 is used to transmit a positioning signal using the power supplied by the wireless power supply module 101. This positioning signal can be used to indicate the location of the electronic device 10. After receiving the positioning signal, the power supply device can quickly and accurately determine the location of the electronic device 10 based on the positioning signal, and then the power supply device can transmit directional electromagnetic waves to the electronic device 10 for efficient and stable wireless power supply.
[0071] In this embodiment, the operating modes of the electronic device 10 may include a positioning mode and a power supply mode. When the electronic device 10 operates in positioning mode, the DC power converted by the wireless power supply module 101 is input to the positioning module 102 to power it. When the electronic device 10 operates in power supply mode, the DC power converted by the wireless power supply module 101 is input to the load module 103 to power it.
[0072] In this embodiment, the electronic device 10 can switch its operating mode based on changes in the power output of the wireless power supply module 101. In one embodiment, in response to changes in the power output of the wireless power supply module 101, the electronic device 10 can operate in either a positioning mode or a power supply mode. Further, the electronic device 10 can operate in either a positioning mode or a power supply mode in response to a comparison between the power output of the wireless power supply module 101 and a first preset value. In one embodiment, the electronic device 10 operates in a positioning mode in response to the power output of the wireless power supply module 101 being less than the first preset value. In another embodiment, the electronic device 10 operates in a power supply mode in response to the power output of the wireless power supply module 101 being greater than or equal to the first preset value.
[0073] The following will be based on Figure 1 Taking electronic device 200a as an example, the electronic device 10 in this application embodiment will be described. The operating modes of electronic device 200a include positioning mode and power supply mode.
[0074] Power supply device 100 broadcasts electromagnetic waves into space. At this time, electronic device 200a's battery is low or malfunctioning. Upon receiving the electromagnetic waves, the wireless power supply module 101 in electronic device 200a converts them into corresponding direct current (DC). If the power output of the wireless power supply module 101 is less than a first preset value, electronic device 200a can operate in positioning mode, using the DC to power positioning module 102 to drive it to transmit positioning signals. Correspondingly, power supply device 100 can receive the positioning signal and confirm the location of electronic device 200a based on it, thus locating electronic device 200a. Then, power supply device 100 can transmit directional electromagnetic waves to electronic device 200a. Upon receiving the electromagnetic waves, the wireless power supply module 101 in electronic device 200a converts them into corresponding DC. If the power output of the wireless power supply module 101 is greater than the first preset value, electronic device 200a can operate in power supply mode, using the DC to power load module 103. For example, the load module 103 of the electronic device 200a may include a battery, controller, display screen, indicator lights, and sensors. Thus, in the event of severe power depletion, zero battery power, or a malfunction of the electronic device 200a, the electronic device 200a can utilize the electromagnetic waves broadcast by the power supply device 100 to feed back a corresponding positioning signal, thereby enabling the power supply device 100 to accurately locate the electronic device 200a and provide efficient power subsequently.
[0075] Understandable, Figure 1 The electronic devices 200b and 200c shown also have batteries installed inside. The operation of electronic devices 200b and 200c can be referred to the description of the corresponding embodiment of electronic device 200a above, and will not be repeated here.
[0076] In one implementation, for Figure 1For electronic devices 200a and 200b, the power supply scenario is generally indoors. Power supply device 100 can typically be installed in living rooms, bedrooms, classrooms, shopping malls, operating rooms, or hospital wards. For electronic device 200c, the power supply scenario is typically a private garage or an underground public parking lot. Multiple power supply devices 100 can be installed in a public parking lot to power a large number of electric vehicles in different locations. For example, when the user-driven electronic device 200c is idle in a garage or parking lot for a long time, and the low-voltage battery and power battery in the electronic device 200c have no remaining power, the wireless power supply module 101 in the electronic device 200c can use the electromagnetic waves broadcast by the power supply device 100 to power the positioning module 102 in the electronic device 200c, driving the positioning module 102 to transmit a positioning signal, thereby enabling the power supply device 100 to accurately locate the electronic device 200c. The power supply device 100 can then transmit directional electromagnetic waves to the electronic device 200c based on this positioning signal, achieving efficient power supply to the electronic device 200c and ensuring the user's real-time driving needs.
[0077] The following will be based on Figure 1 Taking electronic device 200d as an example, the electronic device 10 in this application embodiment will be described. The operating modes of electronic device 200d include positioning mode and power supply mode.
[0078] Similarly, when the location of the electronic device 200d is not confirmed, the power supply device 100 broadcasts electromagnetic waves into space. At this time, the electronic device 200d has neither a built-in battery nor an external power supply. The wireless power supply module 101 in the electronic device 200d receives the electromagnetic waves and converts them into corresponding direct current. In response to the power output of the wireless power supply module 101 being less than a first preset value, the electronic device 200d can operate in positioning mode, thereby using the direct current to power the positioning module 102 to drive it to transmit positioning signals. Correspondingly, the power supply device 100 can receive the positioning signal and, based on the signal, confirm the location of the electronic device 200d, thus locating it. Then, the power supply device 100 can transmit directional electromagnetic waves to the electronic device 200d, and the wireless power supply module 101 in the electronic device 200d, upon receiving these waves, can convert them into corresponding direct current. In response to the power output of the wireless power supply module 101 exceeding a first preset value, the electronic device 200d can operate in power supply mode, thereby using the DC power to supply power to its load module 103. For example, the load module 103 of the electronic device 200d may include a controller, display screen, indicator lights, and speakers. Thus, even without an external power supply, the electronic device 200d can utilize the electromagnetic waves broadcast by the power supply device 100 to feedback a corresponding positioning signal, thereby achieving accurate positioning of the electronic device 200d by the power supply device 100 and subsequent efficient power supply.
[0079] In one implementation, for Figure 1 For the electronic device 200d shown, the power supply scenario is generally an indoor scenario, and the power supply device 100 can generally be installed in offices, conference rooms, classrooms, internet cafes, or libraries.
[0080] In one embodiment, the batteries in the electronic devices 200a, 200b, and 200c can be any one of lead-acid batteries, nickel-cadmium batteries, nickel-iron batteries, nickel-metal hydride batteries, lithium-ion batteries, etc. In one embodiment, electronic device 200c can be... Figure 1 Besides the electric vehicle shown, other devices with the above functions may include balance scooters, electric wheelchairs, golf carts, electric bicycles, electric motorcycles, electric forklifts, drones, robots, and so on. In one embodiment, the electronic device 10 may also be an energy storage system with the above functions, including a large-scale battery pack, such as an energy storage system in a photovoltaic power station or an energy storage system in a residential solar power plant, and so on.
[0081] In summary, this application's embodiments optimize the internal structure of the electronic device, enabling it to receive electromagnetic waves emitted by the power supply device and switch between different operating modes. This allows the power supply device to accurately locate the electronic device and provide efficient and stable wireless power even when the device is low on power or without a battery. Thus, this application's embodiments greatly expand the application scenarios of wireless power supply, overcome the limitations of wireless power supply in passive electronic device situations, and meet the actual needs of users.
[0082] Figure 3 This is a schematic diagram of the structure of another electronic device provided in an embodiment of this application. The technical solution of this application embodiment can be... Figure 3 The example is implemented in the structure shown or a similar structure. Electronic device 10 can be as described above. Figure 1 The electronic device 200d shown does not have a battery installed inside. Figure 3 As shown, the electronic device 10 includes a wireless power supply module 101, a positioning module 102, a load module 103, and a switch module 104. Specifically, the load module 103 may include a functional module 1031, which may include a communication module 11. For example, the functional module 1031 may also include a speaker, a display, an indicator light, a sensor, etc.
[0083] The functions of the wireless power supply module 101 and the positioning module 102 are detailed above. Figure 2 The description of the corresponding embodiments will not be repeated here.
[0084] The switch module 104 is used to connect the wireless power supply module 101 and the positioning module 102, or to connect the wireless power supply module 101 and the load module 103.
[0085] The communication module 11 is used to transmit communication signals using the power supplied by the wireless power supply module 101. This communication signal can indicate one or more of the power supply power of the wireless power supply module 101 and the power consumption level of the functional module 1031. Accordingly, the power supply device receives the communication signal and adjusts the parameters of the transmitted electromagnetic waves based on the information indicated therein to ensure the reliability and efficiency of the wireless power supply at all times. For example, the parameters of the electromagnetic waves may include one or more of frequency, power, and direction.
[0086] In this embodiment, the operating modes of the electronic device 10 may include a positioning mode and a power supply mode. When the electronic device 10 operates in positioning mode, the switch module 104 connects the wireless power supply module 101 and the positioning module 102, allowing the wireless power supply module 101 to supply power to the positioning module. When the electronic device 10 operates in power supply mode, the switch module 104 connects the wireless power supply module 101 and the load module 103, allowing the wireless power supply module 101 to supply power to the load module 103.
[0087] In this embodiment, the electronic device 10 can switch its operating mode based on changes in the power output of the wireless power supply module 101. In one embodiment, in response to a comparison between the power output of the wireless power supply module 101 and a first preset value, the electronic device 10 operates in either a positioning mode or a power supply mode. In one embodiment, in response to the power output of the wireless power supply module 101 being less than the first preset value, the switch module 104 connects the wireless power supply module 101 and the positioning module 102, allowing the wireless power supply module 101 to supply power to the positioning module 102, at which point the electronic device 10 operates in positioning mode. In one embodiment, in response to the power output of the wireless power supply module 101 being greater than or equal to the first preset value, the switch module 104 connects the wireless power supply module 101 and the load module 103, allowing the wireless power supply module 101 to supply power to the load module 103, at which point the electronic device 10 operates in power supply mode.
[0088] The following will be based on Figure 1 Taking electronic device 200d as an example, the electronic device 10 in this application embodiment will be further described. The operating modes of electronic device 200d include positioning mode and power supply mode.
[0089] The power supply device 100 broadcasts electromagnetic waves into space, while the electronic device 200d is not powered by an external power source. Upon receiving the electromagnetic waves, the wireless power supply module 101 in the electronic device 200d converts them into corresponding direct current. In response to the power output of the wireless power supply module 101 being less than a first preset value, the switch module 104 in the electronic device 200d connects the wireless power supply module 101 to the positioning module 102, thereby using the direct current to power the positioning module 102 and drive it to transmit a positioning signal. Correspondingly, the power supply device 100 can receive the positioning signal and, based on it, confirm the location of the electronic device 200d, thus locating it. Then, the power supply device 100 can transmit directional electromagnetic waves to the electronic device 200d, which the wireless power supply module 101 in the electronic device 200d converts into corresponding direct current. In response to the power output of the wireless power supply module 101 exceeding a first preset value, the switch module 104 connects the wireless power supply module 101 to the load module 103, thereby using the DC power to supply power to the load module 103, specifically to the functional module 1031 within the load module 103. Thus, even without an external power supply, the electronic device 200d can utilize the electromagnetic waves broadcast by the power supply device 100 to feedback a corresponding positioning signal, thereby achieving accurate positioning of the electronic device 200d by the power supply device 100 and subsequent efficient power supply.
[0090] In one embodiment, the communication module 11 in the electronic device 200d can transmit communication signals using the power supplied by the wireless power supply module 101. This communication signal can be used to indicate one or more of the power supply power of the wireless power supply module 101 and the power consumption level of the functional module 1031 in the electronic device 200d. In one embodiment, the communication signal can also be used to indicate the device type and location of the electronic device 200d. Accordingly, the power supply device 100 receives the communication signal and adjusts the parameters of the transmitted electromagnetic waves accordingly based on the information contained therein.
[0091] For example, when the energy conversion efficiency of the wireless power supply module 101 in electronic device 200d is low, under the same conditions, the power output of the wireless power supply module 101 in electronic device 200d may be much less than the power output of the wireless power supply module 101 in electronic device 200b. In this case, the power supply device 100 can appropriately increase the power of the transmitted electromagnetic waves based on the power information contained in the communication signal transmitted by electronic device 200d to compensate for the energy conversion efficiency of the wireless power supply module 101.
[0092] For example, when the electronic device 200d plays high-definition video or runs a game, if the power consumption of the functional module 1031 in the electronic device 200d exceeds a preset threshold, the power supply device 100 can appropriately increase the power of the emitted electromagnetic waves to meet the user's needs.
[0093] For example, when the electronic device 200d is in a powered-off or standby state, the power consumption of the functional module 1031 in the electronic device 200d is less than a preset threshold or even almost zero, and the power supply device 100 can appropriately reduce the power of the emitted electromagnetic waves. Thus, embodiments of this application can save energy as much as possible while ensuring the power supply needs of the electronic device, etc.
[0094] In one embodiment, the communication module 11 may integrate a corresponding controller to control the period at which the communication module 11 transmits communication signals to the power supply device 100. Correspondingly, the power supply device 100 can periodically receive the communication signals transmitted by the communication module 11. If the power supply device 100 does not receive the communication signal again within a fixed period, it can determine that the electronic device 10 may have lost power due to relocation or other reasons. Based on this, the power supply device 100 can rebroadcast electromagnetic waves into space to drive the electronic device 10 to switch back to the positioning mode, thereby enabling the power supply device 100 to reposition the electronic device 10. Thus, the embodiments of this application can greatly ensure the efficiency and reliability of long-term wireless power supply.
[0095] In summary, this application embodiment adds a switch module 104 to the electronic device. Based on the different power supplies obtained from different received electromagnetic waves, the switch module 104 can connect different modules, thereby realizing the switching between positioning mode and power supply mode. This ensures that even when the electronic device is not equipped with a battery and has no external power supply, the power supply device can still accurately locate the electronic device to provide efficient and stable wireless power.
[0096] Figure 4 This is a schematic diagram of the structure of another electronic device provided in the embodiments of this application. The technical solutions of the embodiments of this application can be... Figure 4 The example is implemented in the structure shown or a similar structure. Electronic device 10 can be as described above. Figure 1 Any one of the electronic devices 200a, 200b, and 200c shown has a battery installed inside. Figure 4As shown, the electronic device 10 includes a wireless power supply module 101, a positioning module 102, a load module 103, and a switch module 104. The load module 103 may specifically include a functional module 1031 and an energy storage module 1032. In one embodiment, the energy storage module 1032 may be a single battery cell, a battery pack including multiple battery cells, etc. In one embodiment, the communication module 11 and other possible components in the functional module 1031 may be connected to the energy storage module 1032, and the energy storage module 1032 may supply power to the communication module 11 and other possible components in the functional module 1031 when it has power.
[0097] The wireless power supply module 101 is used to receive electromagnetic waves emitted by the power supply device and convert the electromagnetic waves into power for at least one of the positioning module 102, the functional module 1031 and the energy storage module 1032.
[0098] For details on the functions of the positioning module 102, please refer to the above. Figure 2 The description of the corresponding embodiments will not be repeated here.
[0099] The switch module 104 is used to connect the wireless power supply module 101 to the positioning module 102, or to connect the wireless power supply module 101 to the functional module 1031, or to connect the wireless power supply module 101 to the energy storage module 1032.
[0100] The communication module 11 is used to transmit communication signals using the power supplied by the wireless power supply module 101. This communication signal can indicate one or more of the following: the power supply power of the wireless power supply module 101, the power consumption level of the functional module 1031, and the charge level of the energy storage module 1032. Accordingly, the power supply device receives the communication signal and adjusts the parameters of the transmitted electromagnetic waves based on the information indicated. For example, when the communication signal indicates that the charge level of the energy storage module 1032 has not reached 20%, the power supply device can continuously transmit high-power electromagnetic waves to achieve rapid charging of the energy storage module 1032. When the communication signal indicates that the charge level of the energy storage module 1032 has reached 85% or 70%, the power supply device can appropriately reduce the power of the electromagnetic waves, thereby saving energy as much as possible while ensuring user needs are met.
[0101] In this embodiment, the operating mode of the electronic device 10 may include a positioning mode and a power supply mode. Further, based on different power supply objects in the load module 103, this embodiment can further subdivide the power supply mode of the electronic device 10 into a working mode and a charging mode to improve the flexibility of wireless power supply. Specifically, when the electronic device 10 operates in positioning mode, the switch module 104 connects the wireless power supply module 101 and the positioning module 102, allowing the wireless power supply module 101 to supply power to the positioning module. When the electronic device 10 operates in working mode, the switch module 104 connects the wireless power supply module 101 and the functional module 1031, allowing the wireless power supply module 101 to supply power to the functional module 1031. When the electronic device 10 operates in charging mode, the switch module 104 connects the wireless power supply module 101 and the energy storage module 1032, allowing the wireless power supply module 101 to supply power to the energy storage module 1032.
[0102] Understandably, the switching between positioning mode and power supply mode can be referenced above. Figure 2 or Figure 3 In accordance with the description of the embodiments, the switching method between the working mode and the charging mode will be explained below on the premise that the power output of the wireless power supply module 101 is greater than the first preset value.
[0103] In this embodiment, the electronic device 10 can switch between operating mode and charging mode based on changes in the power output of the wireless power supply module 101. In one embodiment, the electronic device 10 operates in either operating mode or charging mode in response to a comparison between the power output of the wireless power supply module 101 and a second preset value. In one embodiment, if the power output of the wireless power supply module 101 is less than the second preset value, the switch module 104 connects the wireless power supply module 101 and the functional module 1031, allowing the wireless power supply module 101 to supply power to the functional module 1031, at which point the electronic device 10 operates in operating mode. In one embodiment, if the power output of the wireless power supply module 101 is greater than or equal to the second preset value, the switch module 104 connects the wireless power supply module 101 and the energy storage module 1032, allowing the wireless power supply module 101 to supply power to the energy storage module 1032, at which point the electronic device 10 operates in charging mode. Furthermore, considering the different battery capacities and varying complexity of functional modules in different electronic devices 10, the switching rules for the aforementioned operating mode and charging mode can also be set in reverse. For example, in response to the power output of the wireless power supply module 101 being less than a second preset value, the switch module 104 connects the wireless power supply module 101 and the energy storage module 1032, allowing the wireless power supply module 101 to supply power to the energy storage module 1032, at which point the electronic device 10 operates in charging mode. For example, in response to the power output of the wireless power supply module 101 being greater than or equal to the second preset value, the switch module 104 connects the wireless power supply module 101 and the functional module 1031, allowing the wireless power supply module 101 to supply power to the functional module 1031, at which point the electronic device 10 operates in operating mode. In one embodiment, the user can set the size of the second preset value and the mode switching rules according to actual needs; this application embodiment does not specifically limit this.
[0104] The following will be based on Figure 1 Taking electronic device 200a as an example, the electronic device 10 in this application embodiment will be described. The operating modes of electronic device 200a include positioning mode and power supply mode, wherein the power supply mode includes working mode and charging mode.
[0105] After locating the electronic device 200a, the power supply device 100 can transmit directional electromagnetic waves to the electronic device 200a. Upon receiving these electromagnetic waves, the wireless power supply module 101 in the electronic device 200a converts them into corresponding direct current. In response to the power output of the wireless power supply module 101 exceeding a second preset value, the switch module 104 in the electronic device 200a connects the wireless power supply module 101 to the energy storage module 1032, thereby using the direct current to power the energy storage module 1032. For example, after a period of time, if the power output of the wireless power supply module 101 falls below the second preset value, the switch module 104 in the electronic device 200a can connect the wireless power supply module 101 to the functional module 1031, thereby using the direct current to power the functional module 1031.
[0106] In this embodiment, the electronic device 10 can also switch between operating mode and charging mode based on the state changes of the load module 103. In one embodiment, the state changes of the load module 103 may include one or more of the changes in the power level of the energy storage module 1032 and the power consumption level of the functional module 1031. In one embodiment, in response to one or more of the energy storage module 1032's power level being greater than a preset power level or the functional module 1031's power consumption being greater than a preset power consumption value, the switch module 104 connects the wireless power supply module 101 and the functional module 1031, allowing the wireless power supply module 101 to supply power to the functional module 1031, at which time the electronic device 10 operates in operating mode. In one embodiment, in response to one or more of the energy storage module 1032's power level being less than a preset power level or the functional module 1031's power consumption being greater than a preset power consumption value, the switch module 104 connects the wireless power supply module 101 and the energy storage module 1032, allowing the wireless power supply module 101 to supply power to the energy storage module 1032, at which time the electronic device 10 operates in charging mode.
[0107] The following will be based on Figure 1 Taking electronic device 200a as an example, the electronic device 10 in this application embodiment will be described. The operating modes of electronic device 200a include positioning mode and power supply mode, wherein the power supply mode includes working mode and charging mode.
[0108] After locating the electronic device 200c, the power supply device 100 can transmit directional electromagnetic waves to the electronic device 200a. Upon receiving these electromagnetic waves, the wireless power supply module 101 in the electronic device 200a converts them into corresponding direct current. For example, at this time, the electronic device 200c can be in standby mode. Responding to the energy storage module 1032 having less than 20% power and the functional module 1031 having low power consumption, the switch module 104 in the electronic device 200a can connect the wireless power supply module 101 and the energy storage module 1032, thereby using the direct current to power the energy storage module 1032. For example, after charging for a period of time, responding to the energy storage module 1032 having more than 20% power, the switch module 104 in the electronic device 200a can connect the wireless power supply module 101 and the functional module 1031, thereby using the direct current to power the functional module 1031. For example, if the electronic device 200a is playing a high-definition video, although the power of the energy storage module 1032 is less than 20%, in response to the high power consumption of the functional module 1031, the switch module 104 in the electronic device 200a can connect the wireless power supply module 101 and the functional module 1031, thereby using the DC power to power the functional module 1031 to meet the user's usage needs.
[0109] In one embodiment, before the energy storage module 1032's charge level reaches 15% or 20%, the switch module 104 can always maintain the connection between the wireless power supply module 101 and the energy storage module 1032, ensuring that the electronic device 10 always operates in charging mode. After the energy storage module 1032's charge level reaches 15% or 20%, in response to changes in the power consumption level of the functional module 1031, the switch module 104 can maintain the connection between the wireless power supply module 101 and the functional module 1031, or maintain the connection between the wireless power supply module 101 and the energy storage module 1032.
[0110] In one embodiment, when the electronic device 10 is operating in charging mode or working mode, if the power output of the wireless power supply module 101 is sufficiently large and the energy storage module 1032 is not fully charged, the switch module 104 can simultaneously connect the wireless power supply module 101 and the energy storage module 1032, as well as the wireless power supply module 101 and the functional module 1031. This allows the wireless power supply module 101 to simultaneously supply power to both the energy storage module 1032 and the functional module 1031, at which point the electronic device can operate in a balanced power supply mode. In this way, the energy transmitted by the power supply equipment can be fully utilized for comprehensive and efficient power supply.
[0111] For example, when the power output of the wireless power supply module 101 is greater than a third preset value, and the power of the energy storage module 1032 is less than 100% or 85%, the switch module 104 can connect the wireless power supply module 101 and the energy storage module 1032, as well as connect the wireless power supply module 101 and the functional module 1031, so as to make full use of the high-power electromagnetic waves emitted by the power supply equipment to supply power to all components in the load module 103. The third preset value is greater than the second preset value.
[0112] In one implementation, Figure 4 The functional module 1031 shown may also include a corresponding power management module for controlling the power and voltage supplied by the wireless power supply module 101 to different objects in the load module 103, thereby improving the flexibility of power supply. Furthermore, Figure 4 The functional module 1031 in the load module 103 of the electronic device 10 shown may also include: a processor, an external memory interface, an internal memory, an audio module, a sensor module, a camera, a display screen, etc.
[0113] The processor may include one or more processing units, such as an application processor (AP), a modem processor, a graphics processing unit (GPU), an image signal processor (ISP), a controller, memory, a video codec, a digital signal processor (DSP), a baseband processor, and / or a neural network processing unit (NPU). The controller may serve as the central nervous system and command center of the electronic device 10. The controller can generate operation control signals based on instruction opcodes and timing signals to control instruction fetching and execution. It should be noted that the different processing units included in the processor may be independent devices or integrated into one or more processors. In some embodiments of this application, the controller can be used to control the period and content of communication signals transmitted by the access module, and can also be used to control the on / off state of the multiplexer included in the switch module 104, etc. These details will not be elaborated here; please refer to the descriptions in the following embodiments.
[0114] The sensor module may include pressure sensors, gyroscope sensors, barometric pressure sensors, magnetic sensors, accelerometers, distance sensors, proximity sensors, fingerprint sensors, temperature sensors, touch sensors, ambient light sensors, bone conduction sensors, etc., and this application embodiment does not specifically limit the types of sensors used. In one embodiment, each sensor module may also integrate its own wireless power supply module 101, positioning module 102, switch module 104, and energy storage module 1032, etc., and can independently complete positioning and receive power from the power supply device through the power supply technology described in the above-described embodiments of this application.
[0115] In one embodiment, the electronic device 10 may further include a wired power supply module for receiving electrical energy input from a wired charger and supplying power to the communication module 11, energy storage module 1032, processor, external memory interface, internal memory, audio module, sensor module, camera, display screen, etc. in the load module 103.
[0116] It should be understood that the structures illustrated in the embodiments of this application do not constitute a specific limitation on the electronic device 10. In some possible embodiments, the electronic device 10 may have more or fewer components than shown in the figures, or combine some components, or split some components, or have different component arrangements. The various components shown in the figures can be implemented in hardware, software, or a combination of hardware and software, including one or more signal processing and / or application-specific integrated circuits. Furthermore, the interface connection relationships between the modules illustrated in the embodiments of this application are merely illustrative and do not constitute a structural limitation on the electronic device 10. In some possible embodiments, the electronic device 10 may also employ different interface connection methods or combinations of multiple interface connection methods as described in the above embodiments.
[0117] Figure 5 This is a schematic flowchart of a method for power supply using electromagnetic waves provided in an embodiment of this application. The following will be combined with... Figure 5 The method flow shown illustrates in detail the power supply technology in the embodiments of this application. For example... Figure 5 As shown, the method may include the following steps S11-S19.
[0118] Step S11: Receive the electromagnetic wave emitted by the power supply equipment and convert the electromagnetic wave into direct current.
[0119] Specifically, the wireless power supply module 101 in the electronic device 10 receives electromagnetic waves emitted by the power supply device and converts the electromagnetic waves into direct current. Figure 6a This is a schematic diagram of the structure of another electronic device provided in an embodiment of this application. For example... Figure 6aAs shown, the wireless power supply module 101 may include a rectifier module 1011, which is connected to a power supply antenna 105. The power supply antenna 105 is used to receive electromagnetic waves emitted by the power supply device, and the rectifier module 1011 is used to receive the electromagnetic waves and convert them into direct current. In one embodiment, the rectifier module 1011 may include multiple diodes.
[0120] Step S12: Compare the DC power supply with the first preset value.
[0121] Specifically, the power output of the DC power supply module 101 is compared with a first preset value. In response to the comparison result of the DC power output and the first preset value, the electronic device 10 operates in positioning mode or power supply mode.
[0122] In one embodiment, the electronic device 10 operates in positioning mode in response to the power output of the wireless power supply module 101 being less than or equal to a first preset value; in another embodiment, the electronic device 10 operates in power supply mode in response to the power output of the wireless power supply module 101 being greater than the first preset value.
[0123] In one embodiment, in response to the power output of the wireless power supply module 101 being less than or equal to a first preset value, the switch module 104 connects the wireless power supply module 101 and the positioning module 102, so that the wireless power supply module 101 supplies power to the positioning module 102, at which time the electronic device 10 operates in positioning mode. In another embodiment, in response to the power output of the wireless power supply module 101 being greater than the first preset value, the switch module 104 connects the wireless power supply module 101 and the load module 103, so that the wireless power supply module 101 supplies power to the load module 103, at which time the electronic device 10 operates in power supply mode.
[0124] In one implementation, such as Figure 6a As shown, the switch module 104 may include a controller 1041 and a toggle switch, such as toggle switch 1.

Figure 6b As shown, the switch 1 can also be a single-pole three-throw switch, wherein the output terminal of the controller 1041 is connected to the A terminal of the switch 1, the B terminal of the switch 1 is connected to the positioning module 102, the C terminal of the switch 1 is connected to the functional module 1031 in the load module 103, and the C' terminal of the switch 1 is connected to the energy storage module 1032 in the load module 103.
[0127] like Figure 6b As shown, the controller 1041 can be used to receive the DC power output by the rectifier module 1011, compare whether the power supply of the DC power is greater than a first preset value, and control the switching switch 1 to connect the rectifier module 1011 and the positioning module 102, or connect the rectifier module 1011 and the functional module 1031, or connect the rectifier module 1011 and the energy storage module 1032 based on the comparison result.
[0128] Figure 6c This is a schematic diagram of the structure of another electronic device provided in an embodiment of this application. In one embodiment, such as... Figure 6c As shown, the switch module 104 may include a controller 1041 and multiple switching switches, such as switching switch 1 and switching switch 2. Among them, as... Figure 6c As shown, switch 1 can be a single-pole double-throw switch, and switch 2 can be a double-pole double-throw switch. The input terminal of controller 1041 is connected to the output terminal of rectifier module 1011, the output terminal of controller 1041 is connected to terminal A of switch 1, terminal B of switch 1 is connected to positioning module 102, terminal C of switch 1 is connected to terminals D and F of switch 2, terminal E of switch 2 is connected to functional module 1031, and terminal G of switch 2 is connected to energy storage module 1032.
[0129] like Figure 6cAs shown, the controller 1041 can be used to receive the DC power output from the rectifier module 1011, compare whether the power supply of the DC power is greater than a first preset value, and control the switching switch 1 to connect the rectifier module 1011 and the positioning module 102 based on the comparison result, or control the switching switches 1 and 2 to connect the rectifier module 1011 and the functional module 1031, or control the switching switches 1 and 2 to connect the rectifier module 1011 and the energy storage module 1032.
[0130] In step S13, the DC power supply is less than or equal to the first preset value, and the electronic device operates in positioning mode.
[0131] Specifically, in response to the power output of the wireless power supply module 101 being less than or equal to a first preset value, the electronic device 10 operates in positioning mode.
[0132] In one embodiment, in response to the power output of the wireless power supply module 101 being less than or equal to a first preset value, the switch module 104 connects the wireless power supply module 101 and the positioning module 102, so that the wireless power supply module 101 supplies power to the positioning module 102, at which time the electronic device 10 operates in positioning mode.
[0133] In one implementation, such as Figure 5 As shown, when the electronic device 10 is operating in positioning mode, it can compare the power output of the wireless power supply module 101 with the first preset value again, and in response to the comparison result of the DC power supply power and the first preset value, the electronic device 10 maintains the current positioning mode or switches to power supply mode.
[0134] Figure 7 This is a schematic diagram of an electronic device operating in positioning mode, provided in an embodiment of this application. In one implementation, such as... Figure 7 As shown, if the power output of the DC power from the rectifier module 1011 is less than or equal to the first preset value, the controller 1041 can control the connection between the A and B terminals of the switch 1, thereby connecting the controller 1041 and the positioning module 102, so that the DC power output from the rectifier module 1011 can be input into the positioning module 102 to power the positioning module 102. At this time, the electronic device 10 is running in positioning mode.
[0135] In one embodiment, the positioning module 102 can generate a corresponding positioning signal using the power supply of the rectifier module 1011, and transmit the positioning signal through the positioning antenna 106 connected to it. Accordingly, the power supply device receives the positioning signal and confirms the position of the electronic device 10 based on the positioning signal.
[0136] In one embodiment, the positioning module 102 may include a cavity oscillator, which is used to transmit a positioning signal under the drive of the DC power output from the rectifier module 1011. This positioning signal is essentially a modulated waveform. The voltage of the DC power is the driving voltage of the cavity oscillator, and the output frequency of the cavity oscillator can be proportional to the DC power voltage.
[0137] In step S14, the DC power supply is greater than the first preset value, and the electronic device operates in power supply mode.
[0138] Specifically, in response to the power output of the wireless power supply module 101 being greater than a first preset value, the electronic device 10 operates in power supply mode.
[0139] In one embodiment, in response to the power output of the wireless power supply module 101 being greater than a first preset value, the switch module 104 connects the wireless power supply module 101 and the load module 103 so that the wireless power supply module 101 supplies power to the load module 103, at which time the electronic device 10 operates in power supply mode.
[0140] In one implementation, such as Figure 5 As shown, when the electronic device 10 is operating in power supply mode, it can compare the power output of the wireless power supply module 101 with the first preset value again, and in response to the comparison result of the DC power supply power and the first preset value, the electronic device 10 maintains the current power supply mode or switches to positioning mode.
[0141] In one implementation, if the DC power supply is greater than a first preset value, then Figure 6a The controller 1041 shown can control the connection between the A and C terminals of the switching switch 1, so that the DC power output by the rectifier module 1011 can be input into the load module 103 to power the load module 103.
[0142] Step S15: Compare the DC power supply with the second preset value.
[0143] Specifically, when the load module of the electronic device 10 includes a functional module and an energy storage module, the power output of the wireless power supply module 101 can be further compared with a second preset value. In response to the comparison result of the DC power supply and the second preset value, the electronic device 10 operates in a working mode or a charging mode.
[0144] In one embodiment, the electronic device 10 operates in a working mode in response to the power output of the wireless power supply module 101 being less than or equal to a second preset value; in another embodiment, the electronic device 10 operates in a charging mode in response to the power output of the wireless power supply module 101 being greater than the second preset value.
[0145] In one embodiment, in response to the power output of the wireless power supply module 101 being less than or equal to a second preset value, the switch module 104 connects the wireless power supply module 101 and the functional module 1031, so that the wireless power supply module 101 supplies power to the functional module 1031, at which time the electronic device 10 operates in a working mode. In another embodiment, in response to the power output of the wireless power supply module 101 being greater than the second preset value, the switch module 104 connects the wireless power supply module 101 and the energy storage module 1032, so that the wireless power supply module 101 supplies power to the energy storage module 1032, at which time the electronic device 10 operates in a charging mode.
[0146] In one implementation, such as Figure 6b As shown, if the controller 1041 determines that the DC power output of the rectifier module 1011 is less than or equal to a second preset value, the controller 1041 can control the connection between terminal A and terminal C of the switch 1, thereby connecting the rectifier module 1011 and the functional module 1031 and supplying power to the functional module 1031. At this time, the electronic device 10 operates in working mode. In one embodiment, as... Figure 6b As shown, if the controller 1041 determines that the power output of the DC power from the rectifier module 1011 is greater than the second preset value, the controller 1041 can control the connection between the A terminal and the C' terminal of the switching switch 1, thereby connecting the rectifier module 1011 and the energy storage module 1032 and supplying power to the energy storage module 1032. At this time, the electronic device 10 is running in charging mode.
[0147] Step S16: Compare the DC power supply with the third preset value.
[0148] Specifically, if the DC power supply is greater than the second preset value, the DC power supply is further compared with the third preset value. In response to the comparison result of the DC power supply and the third preset value, the electronic device 10 operates in charging mode or balancing mode.
[0149] In one embodiment, in response to the power output of the wireless power supply module 101 being greater than a second preset value and less than or equal to a third preset value, the electronic device 10 operates in charging mode; in another embodiment, in response to the power output of the wireless power supply module 101 being greater than the third preset value, the electronic device 10 operates in balanced mode.
[0150] In one embodiment, in response to the power output of the wireless power supply module 101 being greater than a second preset value and less than or equal to a third preset value, the switch module 104 connects the wireless power supply module 101 and the energy storage module 1032, so that the wireless power supply module 101 supplies power to the energy storage module 1032, at which time the electronic device 10 operates in charging mode. In another embodiment, in response to the power output of the wireless power supply module 101 being greater than the third preset value, the switch module 104 connects the wireless power supply module 101 and the energy storage module 1032, and also connects the wireless power supply module 101 and the functional module 1031, so that the wireless power supply module 101 simultaneously supplies power to both the functional module 1031 and the energy storage module 1032, at which time the electronic device 10 operates in balanced mode.
[0151] In one implementation, such as Figure 6c As shown, if the controller 1041 determines that the power output of the DC power from the rectifier module 1011 is greater than a second preset value and less than or equal to a third preset value, then the controller 1041 can control the connection between terminals A and C of the switch 1 and the connection between terminals F and G of the switch 2, thereby connecting the rectifier module 1011 and the energy storage module 1032 and supplying power to the energy storage module 1032. At this time, the electronic device 10 operates in charging mode. In one embodiment, as... Figure 6c As shown, if the controller 1041 determines that the power supply of the DC power output by the rectifier module 1011 is greater than the third preset value, the controller 1041 can control the connection of terminal A and terminal C of the switch 1, and control the connection of terminal D and terminal E and terminal F and terminal G of the switch 2, thereby connecting the rectifier module 1011 with the functional module 1031 and the energy storage module 1032 respectively, and simultaneously supplying power to the functional module 1031 and the energy storage module 1032. At this time, the electronic device 10 operates in balanced mode.
[0152] In step S17, the DC power supply is greater than the third preset value, and the electronic device operates in balanced mode.
[0153] Specifically, in response to the power output of the wireless power supply module 101 being greater than a third preset value, the electronic device 10 operates in a balanced mode.
[0154] In one embodiment, in response to the power output of the wireless power supply module 101 being greater than a third preset value, the switch module 104 respectively connects the wireless power supply module 101 to the functional module 1031 and the energy storage module 1032, so that the wireless power supply module 101 supplies power to the functional module 1031 and the energy storage module 1032, at which time the electronic device 10 operates in a balanced mode.
[0155] In one implementation, such as Figure 5As shown, when the electronic device 10 is operating in balanced mode, the power output of the wireless power supply module 101 can be compared again with the first preset value. Furthermore, the power output can be compared again with at least one of the second and third preset values. In response to one or more of the above comparison results, the electronic device 10 maintains the current balanced mode or switches to positioning mode, working mode, or charging mode.
[0156] Figure 8 This is a schematic diagram of an electronic device operating in power supply mode, provided in an embodiment of this application. In one implementation, such as... Figure 8 As shown, if the controller 1041 determines that the DC power output by the rectifier module 1011 is greater than the third preset value, the controller 1041 can control the connection between the A and C terminals of the switch 1, and control the connection between the D and E terminals and the F and G terminals of the switch 2, thereby connecting the rectifier module 1011 and the functional module 1031, and connecting the rectifier module 1011 and the energy storage module 1032, so as to simultaneously supply power to the functional module 1031 and the energy storage module 1032. At this time, the electronic device 10 can operate in the balanced mode of the power supply mode.
[0157] In one embodiment, the controller 1041 can also obtain the power status of the energy storage module 1032. If the power of the energy storage module 1032 is full or greater than 95%, the controller 1041 can control the connection between the A and C terminals of the switch 1, and control the connection between the D and E terminals and the disconnection between the F and G terminals of the switch 2, thereby connecting the rectifier module 1011 and the functional module 1031 to supply power to the functional module 1031.
[0158] In step S18, the DC power supply is greater than the second preset value and less than or equal to the third preset value, and the electronic device operates in charging mode.
[0159] Specifically, in response to the power output of the wireless power supply module 101 being greater than a second preset value and less than or equal to a third preset value, the electronic device 10 operates in charging mode.
[0160] In one embodiment, in response to the power output of the wireless power supply module 101 being greater than a second preset value and less than or equal to a third preset value, the switch module 104 connects the wireless power supply module 101 and the energy storage module 1032, so that the wireless power supply module 101 supplies power to the energy storage module 1032, at which time the electronic device 10 operates in charging mode.
[0161] In one implementation, such as Figure 5As shown, when the electronic device 10 is operating in charging mode, the power output of the wireless power supply module 101 can be compared again with a first preset value. Furthermore, the power output can be compared again with at least one of a second preset value and a third preset value. In response to one or more of the above comparison results, the electronic device 10 maintains the current charging mode or switches to a positioning mode, a working mode, or a balanced mode.
[0162] Figure 9 This is a schematic diagram of another electronic device structure operating in a power supply mode, provided in an embodiment of this application. In one implementation, such as Figure 9 As shown, if the controller 1041 determines that the power supply of the DC power output by the rectifier module 1011 is greater than the second preset value and less than or equal to the third preset value, then the controller 1041 can control the connection of terminal A and terminal C of the switch 1, and control the disconnection of terminal D and terminal E and the connection of terminal F and terminal G in the switch 2, thereby connecting the rectifier module 1011 and the energy storage module 1032 to supply power to the energy storage module 1032. At this time, the electronic device 10 operates in the charging mode of the power supply mode.
[0163] In step S19, the DC power supply is greater than the first preset value and less than or equal to the second preset value, and the electronic device 10 operates in working mode.
[0164] Specifically, in response to the power output of the wireless power supply module 101 being greater than a first preset value and less than or equal to a second preset value, the electronic device 10 operates in a working mode.
[0165] In one embodiment, in response to the power output of the wireless power supply module 101 being greater than a first preset value and less than or equal to a second preset value, the switch module 104 connects the wireless power supply module 101 and the functional module 1031 so that the wireless power supply module 101 supplies power to the functional module 1031, at which time the electronic device 10 operates in the working mode.
[0166] In one implementation, such as Figure 5 As shown, when the electronic device 10 is operating in charging mode, the power output of the wireless power supply module 101 can be compared again with a first preset value. Furthermore, the power output can be compared again with at least one of a second preset value and a third preset value. In response to one or more of the above comparison results, the electronic device 10 maintains the current operating mode or switches to positioning mode, charging mode, or balancing mode.
[0167] Figure 10 This is a schematic diagram of another electronic device operating in power supply mode, provided in an embodiment of this application. In one implementation, such as Figure 10As shown, if the controller 1041 determines that the power supply of the DC power output by the rectifier module 1011 is greater than the first preset value and less than or equal to the second preset value, then the controller 1041 can control the connection of terminal A and terminal C of the switch 1, and control the connection of terminal D and terminal E of the switch 2, and disconnect terminal F and terminal G, thereby connecting the rectifier module 1011 and the functional module 1031 to supply power to the functional module 1031. At this time, the electronic device 10 operates in the power supply mode.
[0168] It should be noted that in some possible embodiments, the control rules of controller 1041 may be the opposite of steps S18 and S19 described above. That is, when controller 1041 determines that the DC power supply is greater than a first preset value and less than or equal to a second preset value, it can control the D terminal of switch 2 to disconnect from the E terminal and the F terminal to connect from the G terminal, thereby turning on rectifier module 1011 and energy storage module 1032. Correspondingly, when controller 1041 determines that the DC power supply is greater than a second preset value and less than or equal to a third preset value, it can control the D terminal of switch 2 to connect from the E terminal and the F terminal to disconnect from the G terminal, thereby turning on rectifier module 1011 and functional module 1031, and so on. This application embodiment does not specifically limit this, and users can customize the settings according to actual needs.
[0169] In one embodiment, the electronic device 10 of this application can also combine one or more of the following to achieve the switching between the above-mentioned operating mode and charging mode: changes in the output power of the wireless power supply module 101, changes in the state of the energy storage module 1032, and changes in the state of the functional module 1031. For example, changes in the state of the energy storage module 1032 may include changes in the amount of electricity in the energy storage module 1032. Changes in the state of the functional module 1031 may include a power-off state, a standby state, and an operating state, wherein the operating state can be further subdivided into a normal operating state and an overload operating state, etc. In one embodiment, changes in the state of the functional module 1031 can specifically manifest as changes in the power consumption level of the functional module 1031. Further, the switching module 104 can respond to one or more of the following: a comparison result of the DC power supply power with a preset power value, a comparison result of the amount of electricity in the energy storage module 1032 with a preset amount of electricity, and a comparison result of the power consumption of the functional module 1031 with a preset power consumption value, by controlling the conduction of one or more multiple switches within the switching module 104, thereby achieving the switching between the above-mentioned operating mode and charging mode.
[0170] For example, the power preset value may include one or more, such as the first preset value, the second preset value, or the third preset value; the power preset value may include one or more, such as 15%, 90%, and 100%, corresponding to different state changes such as severe power shortage, sufficient power, and full charge; the power consumption preset value may also include one or more, corresponding to different state changes such as power off, standby, normal operation, and overload operation.
[0171] For example, when the DC power supply is greater than a first preset value, and the energy storage module 1032's charge level is less than 15%, Figure 6c The controller 1041 shown can control the switch 2 to disconnect terminals D and E, and connect terminals F and G, thus connecting the rectifier module 1011 and the energy storage module 1032. Once the energy storage module 1032 reaches 20% charge, the controller 1041 can then control the switch 2 to connect terminals D and E, and disconnect terminals F and G, thus connecting the rectifier module 1011 and the functional module 1031.
[0172] For example, when the DC power supply is greater than the second preset value and the energy storage module 1032 has less than 15% power, the controller 1041 can control the D terminal of the switching switch 2 to connect with the E terminal and the F terminal to connect with the G terminal, thereby connecting the rectifier module 1011 and the functional module 1031, as well as connecting the rectifier module 1011 and the energy storage module 1032, and simultaneously supplying power to the functional module 1031 and the energy storage module 1032.
[0173] For example, when the power of the energy storage module 1032 is less than 15%, but the electronic device 10 is running a game or playing a high-definition video, that is, when the power consumption level of the functional module 1031 is high, the controller 1041 can control the D terminal of the switch 2 to connect with the E terminal and disconnect the F terminal from the G terminal, thereby connecting the rectifier module 1011 and the functional module 1031 to supply power to the functional module 1031.
[0174] For example, when the power of the energy storage module 1032 is greater than 90%, but the electronic device 10 is in a powered-off state, that is, when the power consumption of the functional module 1031 is almost zero, the controller 1041 can control the D terminal of the switch 2 to disconnect from the E terminal and connect the F terminal to the G terminal, thereby connecting the rectifier module 1011 and the energy storage module 1032 to supply power to the energy storage module 1032.
[0175] For example, when the energy storage module 1032 has a power level greater than 90% and the DC power supply is less than the second preset value, the controller 1041 can control the D terminal of the switching switch 2 to connect with the E terminal and disconnect the F terminal from the G terminal, thereby connecting the rectifier module 1011 and the functional module 1031 to supply power to the functional module 1031.
[0176] For example, when the energy storage module 1032 has a charge level greater than 95% or reaches 100%, regardless of the DC power supply, the controller 1041 can control the D terminal of the switch 2 to disconnect from the E terminal and the F terminal to disconnect from the G terminal, allowing the electronic device 10 to supply power to the communication module 11 in the load module 1031 and other possible components through its own energy storage module 1032. Simultaneously, the communication module 11 can also transmit communication signals to the power supply equipment, indicating that the energy storage module of the electronic device 10 is fully charged, and the power supply equipment can reduce or stop transmitting electromagnetic waves to it, thereby saving energy as much as possible.
[0177] Thus, in this embodiment of the application, power can be supplied to all or part of the load module 103 by using a multiplexer in the switching module 104 based on the magnitude of the DC power supply and the state changes of the load module. This allows for the full utilization of the electromagnetic waves emitted by the power supply equipment while meeting power supply requirements, thereby achieving efficient and flexible power supply.
[0178] In addition, such as Figures 6a-10 As shown, the communication module 11 is connected to the communication antenna 107. The communication antenna 107 is used to transmit the aforementioned communication signal in power-on mode. For details regarding the technical solution for the communication signal, please refer to the above. Figure 3 and Figure 4 The corresponding implementation examples will not be described in detail here.
[0179] It should be noted that in the above embodiments, the switching of the operating mode of the electronic device 10 mainly depends on the DC power supply. In some possible embodiments, the embodiments of this application may also switch the operating mode of the electronic device based on the DC voltage or current magnitude. It should be understood that, generally, the higher the power supply, the higher the voltage. Correspondingly, the above... Figures 6a-10 In the controller 1041, a voltage comparator can also be used instead of a power comparator. The voltage comparator is used to receive the DC power output from the rectifier module 1011 and compare the voltage of the DC power with one or more preset voltage values, thereby controlling the switching switches 1 and 2 to achieve simpler, more convenient, and faster switching between multiple operating modes, etc., which will not be elaborated here. Please refer to the above for details. Figures 6a-10 Corresponding implementation examples.
[0180] Figure 11This is a schematic diagram of a system structure for power supply using electromagnetic waves, provided in an embodiment of this application. The following will be combined with… Figure 11 The system structure shown further elaborates on the electromagnetic wave power supply technology in this application. For example... Figure 11 As shown, the power supply system includes power supply equipment 20 and electronic equipment 10.
[0181] The power supply device 20 includes a wireless power supply module 201, a positioning module 202, a communication module 203, a control module 204, a power supply antenna 205, a positioning antenna 206, and a communication antenna 207. The control module 204 is connected to the wireless power supply module 201, the positioning module 202, and the communication module 203 respectively; the wireless power supply module 201 is connected to the power supply antenna 205; the positioning module 202 is connected to the positioning antenna 206; and the communication module 203 is connected to the communication antenna 207.
[0182] The electronic device 10 includes a rectifier module 1011, a switch module 104, a positioning module 102, a load module 103, a power supply antenna 105, a positioning antenna 106, and a communication antenna 107. The load module 103 includes a functional module 1031 and an energy storage module 1032. Specifically, the functional module 1031 may include a communication module 11. Figure 11 As shown, the rectifier module 1011 is connected to the power supply antenna 105, the positioning module 102 is connected to the positioning antenna 106, the communication module 11 is connected to the communication antenna 107, and the output terminal of the rectifier module is connected to the switch module 104, and can be grounded through a capacitor. The capacitor can be used for filtering, thereby ensuring the quality of the output DC power.
[0183] like Figure 11As shown, when the location of the electronic device 10 is not confirmed, the control module 204 in the power supply device 20 can control the wireless power supply module 201 to broadcast electromagnetic waves into space through the power supply antenna 205. The power supply antenna 105 in the electronic device 10 receives the electromagnetic waves and inputs them to the rectifier module 1011. The rectifier module 1011 converts the electromagnetic waves into DC power and inputs it to the switch module 104. Based on the fact that the power supply of the DC power is less than a first preset value, the switch module 104 turns on the rectifier module 1011 and the positioning module 102, thereby supplying power to the positioning module 102. At this time, the electronic device 10 operates in positioning mode. In one embodiment, the electronic device 10 can operate in positioning mode by default. The positioning module 102 uses the power supply of the rectifier module 1011 to transmit a positioning signal through the positioning antenna 106 connected to it. Correspondingly, the positioning antenna 206 in the power supply device 20 receives the positioning signal and inputs it to the positioning module 202. The positioning module 202 analyzes the positioning signal to obtain the location information of the electronic device 10. Furthermore, the control module 204 in the power supply device 20 obtains the location information of the electronic device 10 from the positioning module 202, and controls the wireless power supply module 201 to transmit directional electromagnetic waves to the electronic device 10 through the power supply antenna 205 based on the location information. The power supply antenna 105 in the electronic device 10 receives the electromagnetic waves and inputs them to the rectifier module 1011. The rectifier module 1011 converts the electromagnetic waves into DC power and inputs it to the switch module 104. Based on the fact that the power supply of the DC power is greater than a first preset value, the switch module 104 turns on the rectifier module 1011 and the load module 103, thereby supplying power to the load module 103. At this time, the electronic device operates in power supply mode.
[0184] like Figure 11 As shown, when the electronic device 10 is operating in power supply mode, the communication module 11 in the functional module 1031 can periodically transmit communication signals to the power supply device 20 through the communication antenna 107 connected to it. The communication antenna 207 in the power supply device 20 receives the communication signal and transmits it to the communication module 203 connected to it. Based on the communication signal, the communication module 203 parses and obtains various information about the current electronic device 10, such as the device type of the electronic device 10, the power supply power of the wireless power supply module 101, the power consumption level of the functional module 1031, and the power of the energy storage module 1032. Then, the control module 204 obtains this information from the communication module 203 and adjusts the power, frequency, direction, and other parameters of the electromagnetic waves emitted by the wireless power supply module 201 accordingly, thereby achieving efficient and flexible wireless power supply.
[0185] In one implementation, when the communication module 203 in the power supply device 20 does not receive a communication signal transmitted by the electronic device 10 for an extended period, the communication module 203 can send a message to the control module 204, indicating that the current location of the electronic device 10 may have changed, resulting in the electronic device 10 losing power. At this time, the control module 204 can re-control the wireless power supply module 201 to broadcast electromagnetic waves into space through the power supply antenna 205, thereby triggering the electronic device 10 to switch to positioning mode again, driving the positioning module 102 to retransmit the positioning signal, so that the power supply device 20 repositions the electronic device 10, and then restores power to the electronic device 10, and so on.
[0186] It should be noted that, Figure 11 The system architecture shown is for illustrative purposes only and does not constitute a specific limitation on the electronic device 10 and the power supply device 20. In some possible embodiments, the electronic device 10 and the power supply device 20 may have more or fewer components than shown in the figures, or combine some components, or split some components, or have different component arrangements. The various components shown in the figures may be implemented in hardware, software, or a combination of hardware and software, including one or more signal processing and / or application-specific integrated circuits.
[0187] In summary, this application provides an electronic device powered by electromagnetic waves. The internal structure of the electronic device is optimized, enabling it to switch between different operating modes based on the different characteristics of the electromagnetic waves emitted by the power supply device. For example, when the power supply power is low, it switches to a positioning mode to emit a positioning signal, allowing the power supply device to accurately locate the electronic device and thus emit directional electromagnetic waves to achieve efficient power supply. Alternatively, when the power supply power is high, it can switch to a power supply mode to use the DC power converted from the electromagnetic waves to power the load within the electronic device. Thus, this application provides accurate positioning and efficient, stable wireless power supply for the electronic device even when it is low on power or without a battery. This greatly expands the application scenarios of wireless power supply, solves the limitations of wireless power supply in passive situations, and meets the actual needs of users.
[0188] Furthermore, in this embodiment, the power consumption of the positioning module in the electronic device is extremely low, meaning the power required for the positioning module is very low; a small amount of DC power is sufficient to drive the positioning module to transmit positioning signals. Therefore, this embodiment can ensure accurate positioning of the electronic device by the power supply equipment over a wide range.
[0189] Accordingly, this application also provides a system for power supply using electromagnetic waves, including a power supply device and an electronic device. When the location of the electronic device is not confirmed, the power supply device can first broadcast low-power electromagnetic waves into space to drive the electronic device to switch to a positioning mode and emit a positioning signal. Then, the power supply device can confirm the location of the electronic device based on the positioning signal and directionally emit higher-power electromagnetic waves towards it, thereby achieving efficient and stable wireless power supply.

[0191] Step S301: The electromagnetic waves are converted and supplied to at least one of the positioning module or the load module via the wireless power supply module.
[0192] Step S302: When the electronic device is operating in positioning mode, power is supplied to the positioning module through the wireless power supply module; when the electronic device is operating in power supply mode, power is supplied to the load module through the wireless power supply module.
[0193] Step S303: A positioning signal is transmitted through the positioning module. The positioning signal is used to indicate the position of the electronic device.
