[0052] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work belong to the scope of protection of the present application. The embodiments in the present application and the features in the embodiments can be combined with each other arbitrarily without conflict. The steps shown in the flowchart of the drawings can be executed in a computer system such as a group of computer executable instructions. Moreover, although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that here.
[0053] As described above, for the low-power terminal, there is a problem of long charging time when charging by using the electromagnetic energy signal, and by using the scheme provided in the present application, the first component for protecting and / or supporting the first device can be used to transmit the energy signal to the second device to charge the second device, which can improve the receiving power of the second device receiving the energy signal, thereby reducing the charging time of the second device.
[0054] The technical solutions of the present application will be described in further detail below in combination with the drawings and specific embodiments of the present application.
[0055] Figure 1 Flowchart for implementing the charging method in the present application Figure One As shown in Figure 1 , it comprises:
[0056] Step 101, receiving the energy demand information sent by the second device in a predetermined range by the first device;
[0057] Step 102, determining the energy transmission parameters of the antenna array on the first component based on the energy demand information;
[0058] Step 103, controlling the antenna array to transmit the energy signal based on the energy transmission parameters, and the energy signal is used to charge the second device.
[0059] In the present application, the method can be applied to the first device, which can be a terminal such as a tablet computer, a mobile phone, an electronic book, etc. with a volume greater than a preset size. Here, the volume of the first device can determine the output power of the energy transmission end on the first device, so theoretically, the larger the volume of the first device, the greater the output power, and the faster the charging speed of the second device. As shown in formula (I):
[0060]
[0061] Wherein, P r is the received power; P t is the transmitted power; G t is the transmitting antenna power gain; G r is the receiving antenna power gain; D is the distance between the transmitter and the receiver in meters, and λ is the wavelength in meters, equal to 300 / f MHz. The received power is a function of the square of the wavelength. Therefore, the lower the frequency, the greater the received power. And the volume of the first device is large, P t and G t are large. In this way, the present application can increase the energy transmission power of the transmitting end (the first device end) without adding other additional components, by taking advantage of the large volume of the first device.
[0062] In the present application, the first device has a first component for protecting and / or supporting the body of the first device. For example, the first component can be a protective cover, a protective sleeve, a support frame, a Folio accessory, etc. of the first device. When the first component is the protective cover, the protective cover can be a rear cover of the first device, which can be an integrally formed structure with the first device or can be buckled to the body of the first device. When the first component is a protective sleeve, a Folio accessory or a support frame, the protective sleeve, the Folio accessory or the support frame can exist separately from the first device. The first component can be provided with an antenna array surface, and the first device can be controlled to emit energy signals through the antenna array surface to charge the second device. Since the volume of the first device in the present application is generally large, charging the second device through the first component of the first device can improve the charging efficiency of the second device.
[0063] In the present application, the first device is provided with a Bluetooth chip and / or a WIFI chip, which can be connected in communication with the second device. Based on the communication connection, the energy demand information transmitted by the second device can be received within a predetermined range. Here, the predetermined range can refer to a preset distance range, and the distance range is related to the Bluetooth chip or the WIFI chip. When the first device is connected in communication with the second device through the Bluetooth chip, the predetermined range can be the distance range corresponding to the Bluetooth chip. When the first device is connected in communication with the second device through the WIFI chip, the predetermined range can be the distance range corresponding to the WIFI chip.
[0064] Here, the Bluetooth chip and the WIFI chip can be provided on the mainboard of the first device, or can be provided on the first component of the first device. In this case, the specific position of the Bluetooth chip and the WIFI chip is not limited.
[0065] In the present application, when the second device sends the energy demand information to the first device, the energy demand information can include the power state information, the battery load information or the energy power parameter of the second device, or any combination thereof.
[0066] If the energy demand information is the power state information, the first device can determine the current power value of the second device based on the power state information, compare the current power value of the second device with a first power threshold, and if the comparison result indicates that the current power value of the second device is less than the first power threshold, indicating that the second device is currently out of power, the first device can control the antenna array on the first component to traverse all antenna transmission beams in the beamforming network to determine a beam position point with the maximum beam efficiency in the antenna transmission beams; then determine the energy transmission power and the energy transmission direction corresponding to the beam position point with the maximum beam efficiency as the target transmission power and the target transmission direction of the antenna array on the first component. Then control the antenna array on the first component to transmit an energy signal based on the target transmission power and the target transmission direction to charge the second device.
[0067] For example, the first power threshold is 50%, 30% or 20% of the total power threshold of the second device.
[0068] If the energy demand information is the battery load information, the first device can determine the energy receiving power of the second device based on the battery load information; then determine the energy receiving power as the energy transmission power of the antenna array on the first component, and control the antenna array on the first component to transmit an energy signal based on the energy receiving power to charge the second device.
[0069] If the energy demand information is the energy power parameter, the first device can determine the power corresponding to the energy power parameter as the energy transmission power of the antenna array on the first component, and control the antenna array on the first component to transmit an energy signal based on the power corresponding to the energy power parameter to charge the second device.
[0070] Here, the second device can be a low-power device, for example, the second device can be a Bluetooth headset, smart glasses, a smart watch, a hearing aid, etc.
[0071] In the present application, the first component of the first device further includes an energy emission unit. When the first device controls the antenna array surface in the first component to traverse all antenna emission beams in the beamforming network to determine the beam position with the maximum beam efficiency in the antenna emission beams, the first device can control the energy emission unit in the first component to emit an energy signal. The energy signal is emitted by the antenna unit in the antenna array surface to the second device. After receiving the energy signal, the second device sends a backwave signal of the energy signal to the first device. After receiving the backwave signal returned by the second device based on the energy signal, the first device determines the corresponding beam position of the backwave signal in the antenna emission beam as the beam position with the maximum beam efficiency.
[0072] Here, the energy emission unit includes but is not limited to a Bluetooth chip and a WIFI chip.
[0073] In the present application, the second device can also be preconfigured with a threshold or threshold range of energy emission power. When the second device needs to be charged, the second device can send the threshold or threshold range of energy emission power to the first device. Based on the threshold or threshold range of energy emission power, the first device can control the antenna array surface on the first component to emit an energy signal to the second device with an energy emission power within the threshold or threshold range of energy emission power to charge the second device.
[0074] In the present application, when the first device controls the antenna array surface on the first component to emit an energy signal based on the energy emission parameter, the first device can also perform antenna multiplexing with a target antenna on the first device. That is, the first device can also detect the current use state of other antennas in the first device. If the detection result represents that there is a target antenna in the first device that is currently in an idle state, the first device can control the antenna array surface on the first component and the target antenna in the first device to emit an energy signal simultaneously based on the energy emission parameter. In this way, the power consumption of the first device can be reduced.
[0075] Here, the position of the target antenna is different from the position of the antenna array surface on the first component. For example, the target antenna is located on the frame periphery of the first device, and the antenna array surface is located on the back cover of the first device. Alternatively, the target antenna is located in a first region of the back cover of the first device, and the antenna array surface is located in a second region of the back cover of the first device. The first region and the second region have a preconfigured distance to prevent the antennas in the first region and the antennas in the second region from interfering with each other.
[0076] In one scenario, a user is watching a local video on a tablet. Since local videos do not require a network connection, the tablet can detect that the target antenna on the tablet is idle. In another scenario, a user is video chatting on a tablet. Since video chatting requires a network connection to transmit signals, the tablet can detect that the target antenna on the tablet is currently occupied.
[0077] Here, the target antenna can refer to an antenna that transmits signals to a base station for data transmission between the first device and other devices. The antenna array on the first component can refer to an antenna used to transmit energy signals to the second device for charging the second device.
[0078] In this application, in order to reduce the power consumption of the first device, the first device can also detect the current working state of the first device. If the detection result indicates that the first device is currently in an idle state and / or a charging state, then any of the method steps 101 to 103 above are executed.
[0079] In one implementation, the first device can detect the total occupancy parameter of the central processing unit (CPU) of the first device, and if the total occupancy parameter of the CPU is less than a parameter threshold, it is determined that the first device is currently in an idle state.
[0080] In another implementation, the first device can detect a charging signal on the first component; if the charging signal is detected, it is determined that the first device is currently in a charging state.
[0081] Here, the first component of the first device may be equipped with a Universal Serial Bus (USB) interface. When a signal from the USB interface on the first component is detected, it is determined that the first device is currently in a charging state.
[0082] Here, the first component of the first device may also be provided with a POGO PIN interface. When the signal of the POGO PIN interface on the first component is detected, it is determined that the first device is currently in a charging state.
[0083] In this application, when the first device controls the antenna array on the first component to transmit an energy signal toward the second device, the energy signal can be obtained from the Bluetooth chip and WIFI chip in the first device through the POGO PIN interface on the first component.
[0084] In the present application, the first device can also receive energy demand information sent by a plurality of second devices within a set distance range, and determine the number of second devices according to the number of received energy demand information, and then group the antenna units on the antenna array surface of the first component according to the number of second devices, wherein each group of antenna units corresponds to a second device. Then, based on the corresponding energy transmission parameters determined according to the energy demand information sent by each second device, the energy signal is transmitted to the corresponding second device by each group of antenna units, and the energy signal is used to charge the corresponding second device.
[0085] For example, the first device is a tablet computer, which receives energy demand information sent by two second devices (such as a Bluetooth headset and a smart watch) within a preset Bluetooth distance range, and divides the antenna units on the antenna array surface of the first component (such as the back cover) of the tablet computer into two groups (such as 100 antenna units on the antenna array surface, which are divided into group A and group B, and each group has 50 antenna units). Then, based on the energy demand information sent by the Bluetooth headset, it is determined that the Bluetooth headset needs an energy power of A1, and the antenna units in group A are controlled to provide an energy signal to the Bluetooth headset with an energy power of A1 to achieve charging of the Bluetooth headset; based on the energy demand information sent by the smart watch, it is determined that the smart watch needs an energy power of B1, and the antenna units in group B are controlled to provide an energy signal to the smart watch with an energy power of B1 to achieve charging of the smart watch. In this way, the purpose of simultaneously charging multiple low-power devices can be achieved.
[0086] In the present application, the first device can also determine the current power state parameter of the second device during the process of transmitting the energy signal to the second device, and compare the current power state parameter of the second device with the second power threshold. If the comparison result represents that the current power state parameter of the second device is greater than or equal to the second power threshold, the antenna array surface on the first component stops transmitting the energy signal to the second device.
[0087] For example, the second power threshold is 95%, 98% or 100% of the total power of the second electronic device.
[0088] Here, the first device can receive the power state parameter sent by the second device during the process of providing charging energy to the second device; or can send a request for obtaining the power state to the second device during the process of providing charging energy to the second device, and the second device sends the current power state parameter of the second device to the first device based on the request.
[0089] In the present application, the first device can also detect the connection state between the second device and the first device within a predetermined range based on the communication connection with the second device, and if it is detected that the second device is disconnected from the first device, the first device controls the antenna array on the first component to stop transmitting energy signals to the second device.
[0090] In the present application, when the first device controls the antenna array on the first component to transmit energy signals based on energy transmission parameters, the first device can transmit at least one of directional radio frequency energy signals, WIFI radio frequency signals, and millimeter wave energy signals.
[0091] The present application uses the first component for protecting and / or supporting the first device to realize the transmission of energy signals to the second device to charge the second device, which can improve the receiving power of the second device receiving the energy signals, thereby reducing the charging time of the second device.
[0092] Figure 2 The flow of the charging method in the present application is shown Figure Two As shown in Figure 2 includes:
[0093] Step 201, the first device opens the power switch of "providing radio frequency energy for other devices" in the setting;
[0094] Step 202, the first device detects the charging signal on the first component;
[0095] Here, the charging signal includes at least one of POGO PIN signal and USB signal; through the charging signal, it can be determined whether the first device is in a connected state with the charging back cover.
[0096] Step 203, the first device establishes a communication connection with the second device through Bluetooth protocol or WIFI protocol;
[0097] Step 204, when it is determined that the second device needs to be charged, the first device controls the antenna array on the first component to start transmitting energy signals;
[0098] Here, the energy signal includes but is not limited to signals of 2G, 3G, 4G, 5G frequency bands, WIFI frequency band signals, and millimeter wave frequency band signals.
[0099] Here, the first component can be provided with a radio frequency amplification circuit, a beam forming network (or a multi-beam network), and a phase shift circuit. The antenna array of the first component is composed of a plurality of antenna units, and each antenna unit corresponds to a radio frequency amplification circuit and a phase shift circuit. When the first device controls the antenna array of the first component to emit an energy signal, specifically, after the energy emission unit in the first device emits a radio frequency signal, the radio frequency signal is distributed to the radio frequency amplification circuit and the phase shift circuit of each path through the beam forming network. After the radio frequency signal is processed by the radio frequency amplification circuit and the phase shift circuit of each path, it is given to each antenna unit, and then radiated out through each antenna unit. The radiated radio frequency signal can synthesize a whole directional antenna beam in space.
[0100] Here, the first component can be provided with a POGO PIN interface, and the radio frequency amplification circuit and the phase shift circuit, the beam forming network are powered through the POGO PIN interface.
[0101] Step 205, the first device determines the beam efficiency maximum beam site, and continuously controls the antenna array to emit an energy signal;
[0102] Step 206, receiving the charging state parameter sent by the second device, if the charging state parameter is greater than or equal to the power threshold, controlling the antenna array on the first component to stop emitting an energy signal.
[0103] Figure 3 The flow of the charging method in the present application is realized Figure Three As shown in the figure, it includes: Figure 3
[0104] Step 301, establishing a first communication connection with the first device within a predetermined range, and sending energy demand information to the first device through the first communication connection;
[0105] Step 302, receiving the energy signal sent by the first component of the first device based on the energy demand information, the energy signal is used to charge the second device, wherein the first component is used to protect and / or support the first device.
[0106] In the present application, the charging method is applied to the second device, which can be a low-power Bluetooth headset, a smart watch, a smart bracelet, smart glasses, etc. The second device can be connected with the first device through Bluetooth protocol or WIFI protocol. The energy signal emitted by the first device is received through the communication connection. The second device is provided with a matching circuit, a rectifier circuit and a load circuit, and when the second device receives the energy signal emitted by the first device through the communication connection, the energy signal is processed by the matching circuit, the rectifier circuit and the load circuit and reaches the battery of the second device.
[0107] In the present application, the second device can also detect the usage state of the second device. If the detection result indicates that the second device is currently in the usage state, the first antenna unit in the second device is switched from the first path to the second path to establish the first communication connection with the first device through the second path. In this way, the purpose of obtaining charging energy from the first device can be achieved by multiplexing the original antenna on the second device without adding an antenna.
[0108] Of course, in order to ensure the performance of the earphone, an antenna unit can also be added to the second device. When it is detected that the second device is currently in the usage state, the second antenna unit in the second device is enabled to establish the first communication connection with the first device through the second antenna unit.
[0109] Here, the second antenna unit and the first antenna unit are independent of each other.
[0110] In one implementation, the second device can detect the connection relationship between the second device and a charging component for providing electrical energy to the second device. If the connection relationship indicates that the second device and the charging component are in a disconnected state, it is determined that the second device is currently in the usage state, and the step of establishing the first communication connection with the first device is performed.
[0111] For example, the second device is a Bluetooth earphone, and the charging component for providing electrical energy to the second device is an earphone box. When the Bluetooth earphone is taken out of the earphone box, it indicates that the second device is in the usage state. When the Bluetooth earphone is in the earphone box, it indicates that the second device is in the non-usage state, and the Bluetooth earphone can be charged through the earphone box.
[0112] In another implementation, the second device can detect a current sound signal. If a sound signal is detected, it is determined that the second device is currently in the usage state, and the step of establishing the first communication connection with the first device is performed.
[0113] For example, the second device is a Bluetooth earphone, and the current Bluetooth earphone is outputting sound, which indicates that the Bluetooth earphone is currently in the usage state. In this case, the scheme of adding an antenna unit is required, so that the earphone can output sound and charge at the same time.
[0114] In the present application, when the second device receives charging energy from the first device by multiplexing the original antenna in the second device, a switch circuit can be provided in the second device to switch the first antenna unit from the first path to the second path by controlling the switch circuit.

[0117] Here, the signal receiving component 403 includes but is not limited to a Bluetooth chip, a WIFI chip. The first device 400 can establish a communication connection with the second device 500 through the Bluetooth chip or the WIFI chip, and interact information with the second device 500 within the predetermined distance range corresponding to the Bluetooth chip or the WIFI chip.
[0118] The first component 402 includes but is not limited to a protective cover, a protective sleeve, a support, a Folio accessory. The protective cover is also called the back cover of the first device 400, which is integrated with the body 401 or is connected with the body 401 by clamping. The protective sleeve, the support, and the Folio accessory can be physically separated from the body 401 and exist independently.
[0119] Here, the meaning of existing independently can mean that it can be sold independently, or it can be sold together with the first device 400 as an accessory of the first device 400.
[0120] In this application, the signal receiving component 403, the controller 404, and the antenna array surface 4021 are all arranged inside the first device 400, which is represented by a dashed line in the figure.
[0121] In the preferred scheme, the first component 402 can also be provided with a radio frequency transmitter 4022 for emitting a radio frequency signal, which includes but is not limited to signals of 2G, 3G, 4G, 5G, Bluetooth, WIFI, etc.

[0172] Figure 8 Structure of the second device in the present application Figure 8 As shown in the figure, the second device 800 includes:
[0173] The body 801, the energy collection module 802, the controller 803 and the battery 804, wherein the energy collection module 802 is used to receive the energy signal transmitted by the first device, and charge the battery 804 based on the energy signal.
[0174] Here, the second device can establish a communication connection with the first device within a predetermined range through a Bluetooth protocol or a WIFI protocol, and the controller 803 can control the second device to send energy demand information to the first device based on the communication connection. The energy demand information includes but is not limited to at least one of the state information, the battery load information, and the energy power parameter. The energy collection module 802 can receive the energy signal transmitted by the first component of the first device based on the energy demand information, and the battery 804 can be charged through the energy signal.
[0175] Here, the first component is a protective shell, a protective sleeve, a support, etc. used to protect and / or support the first device.
[0176] Before the first device starts to charge the second device, the antenna array on the first component can traverse all antenna beams in the beamforming network and send an energy signal to the second device; when the energy collection module 802 in the second device receives the energy signal, the controller 803 can determine the beam efficiency of the wave position point with the maximum energy power in the energy signal, and control the second device to send the wave position point with the maximum beam efficiency to the first device through the Bluetooth protocol or the WIFI protocol. So that the first device transmits an energy signal to the second device based on the wave position point with the maximum beam efficiency.
[0177] In this application, the second device can have a first antenna unit 805, through which the energy signal transmitted by the first device can be received.
[0178] Here, the first antenna unit 805 can be an antenna originally existing in the second device for data transmission, that is, the energy collection module 802 can be multiplexed with the original antenna in the second device, thereby reducing the cost of the antenna.
[0179] Here, the first antenna unit 8025 can transmit the same frequency signal as the transmitting end in the first device.
[0180] In this application, the energy harvesting module 802 may include a matching circuit 8021, a rectifier circuit 8022, a load circuit 8023, and a controller 8024. When the energy signal transmitted by the first device is received by the first antenna unit 805 in the second device 800, the energy signal can be made to enter the rectifier circuit 8022 as much as possible through the matching circuit 8021. Then, the energy signal can be converted into a DC signal required by the battery 804 through the rectifier circuit 8022. Then, the DC signal can enter the battery 804 through the load circuit 8023.
[0181] In one implementation, the controller 803 can determine whether the second device is currently in a wearing state or in a disconnected state from the charging component used to charge the second device based on the current usage state of the second device. In this case, the controller controls the first antenna unit 805 to switch from the first path to the second path so that the first antenna unit 805 can establish a communication connection with the first device through the second path.
[0182] For example, the second device is a Bluetooth headset, and the charging component for the Bluetooth headset can be the headset case. When the Bluetooth headset is not in the headset case, it is determined that the Bluetooth headset is in use; when the Bluetooth headset is in the headset case, it is determined that the Bluetooth headset is in charging mode. Alternatively, the current sound signal of the Bluetooth headset can be detected. If a sound signal is detected, it means that the Bluetooth headset is outputting sound, indicating that the Bluetooth headset is in use.
[0183] Here, when the first antenna unit 8025 is multiplexed, the second device 800 may also include a switching circuit 806, which controls the switching circuit 806 to switch the first antenna unit 805 between the first path and the second path.
[0184] like Figure 9 As shown in this application, the energy harvesting module 802 may also include a second antenna unit 8025 with a specific frequency. When the controller 803 determines that the second device is currently in use (worn or disconnected from the charging component) based on the current usage state of the second device, it controls the second antenna unit 8025 to enable so that the second antenna unit 8025 can establish a communication connection with the first device via Bluetooth or WIFI protocol.
