[0063] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices consistent with some aspects of the present disclosure as detailed in the appended claims.

[0064] The present disclosure provides an electronic device. The above receiver system can be applied to electronic devices. The electronic device can include but is not limited to a smart phone, a tablet computer, a laptop computer, a PDA, a wearable device (such as a smart watch, a smart bracelet, a pedometer), etc., which can be selected according to the specific scenario and is not limited here.

[0065] See also Figure 1 The electronic device 1 includes an antenna module 10, a load 20 and a receiver system 30. The receiver system 30 is electrically connected to the antenna module 10 and the load 20 respectively. The antenna module 10 is used to receive a radio frequency signal; the receiver system 30 is used to perform time division and power division on the radio frequency signal, and convert the divided radio frequency signal into a target power and a target signal matching the load.

[0066] Continue to see Figure 1 The receiver system 30 includes a segmentation module 31 and a conversion module 32; the segmentation module 31 is electrically connected to the antenna module 10 and the conversion module 32 respectively, and the conversion module 32 is electrically connected to the load 20. The segmentation module 31 is used to perform time segmentation and power segmentation on the RF signal in each time slot period. The conversion module 32 is used to convert the segmented RF signal into a target power and a target signal that match the load.

[0067] In one example, the segmentation module 31 can divide each time slot cycle into a first time slot and a second time slot, that is, the time slot cycle includes the first time slot and the second time slot. In addition, the segmentation module performs different operations in each time slot to achieve the effect of time segmentation. For example, the segmentation module 31 is used to output the power supply energy and communication signal corresponding to the RF signal in the first time slot of each time slot cycle. During the first time slot, the power supply energy and the communication signal are extracted from the RF signal to achieve the effect of power segmentation, for example, the communication signal corresponding to the RF signal is output in the second time slot of each time slot cycle. The conversion module 32 is used to convert the power supply energy into a target power matching the load 20 and to convert the communication signal into a target signal matching the load 20. In this way, the hybrid segmentation method combining time segmentation and power segmentation of the RF signal in this embodiment can improve the performance of information transmission and energy transmission.

[0068] It should be noted that the RF signal is the energy wave obtained after the antenna module receives the spatial microwave. The energy wave includes a carrier and a signal modulated onto the carrier, and the carrier power will be much greater than the signal power. For the convenience of description, the energy corresponding to the carrier is called wireless energy, which will be collected, converted, stored, and processed to ultimately meet the power supply needs of the load. The above communication signal is used for communication between the receiver system and the transmitter. It carries instructions and responses of corresponding functions, etc., and can be set according to specific scenarios.

[0069] In one embodiment, see Figure 2 , the splitting module 31 includes a time splitting submodule 311, a power splitting submodule 312 and a signal decoding submodule 313; the time splitting submodule 311 is electrically connected to the power splitting submodule 312 and the signal decoding submodule 313 respectively; the power splitting submodule 312 and the signal decoding submodule 313 are electrically connected to the conversion module 32 respectively. Among them,

[0070] The time division submodule 311 is used to switch the antenna module to a first switching state in a first time slot of each time slot cycle and to switch the antenna module to a second switching state in a second time slot of each time slot cycle;

[0071] The power division submodule 312 is used to output the power supply energy and the communication signal corresponding to the radio frequency signal to the conversion module 32 when the antenna module 10 is switched to the first switch state;

[0072] The signal decoding submodule 313 is used to output a communication signal corresponding to the radio frequency signal to the conversion module 32 when the antenna module 10 is switched to the second switch state.

[0073] In this embodiment, the time division submodule 311 can divide each time slot period into a first time slot and a second time slot, and perform different operations on the RF signal in each time slot, so as to achieve the effect of dividing the RF signal in time. The power division submodule 312 can perform power division on the RF signal during the first time slot to obtain power supply energy and communication signals, and the signal decoding submodule 313 can perform decoding operations on the RF signal during the second time slot. In this way, the above-mentioned submodules can be combined to perform time and power mixed division on the RF signal, which can improve the efficiency of information and energy transmission.

[0074] In one embodiment, see Figure 3 The time division submodule 311 includes a communication detection control unit 3111 and a first switch 3112; the communication detection control unit 3111 is electrically connected to the antenna module 10 and the first switch 3112 respectively; the first switch 3112 is electrically connected to the power division submodule 312 and the signal decoding submodule 313 respectively;

[0076] The first switch 3112 is connected to the power splitting sub-module 312 in a first switch state, and is connected to the signal decoding sub-module 313 in a second switch state.

[0081] It should be noted that the energy ratio is a power control factor. Due to the large range of RF signals and their susceptibility to interference, and in the case of multi-user loads, the load controls and adjusts the transmit power and link gain based on the information it provides to prevent the base station RF signal transmitter from overloading or under-transmitting energy, accurately control the load energy size, and ensure that the signal is not interfered with, thereby achieving a balance between energy and signal.

[0082] In this embodiment, the detection control unit 3122 is used to determine the energy ratio, which is equivalent to determining the energy split point; and the energy ratio and the second switch state are combined to determine the transmission channel of the radio frequency signal, so as to achieve the effect of power splitting the radio frequency signal.

[0087] The signal conversion submodule 322 is used to decode the received communication signal and output the decoded signal to the controller submodule 323 and the rectifier filter submodule 324;

[0088] The controller submodule 323 is used to control the rate at which the energy conversion submodule 321 collects energy according to the decoded signal to adjust the power of the output energy; and is also used to control the rate at which the signal conversion submodule 322 receives energy according to the decoded signal to adjust the power of the output decoded signal;

[0089] The rectification and filtering submodule 324 is used for rectifying and filtering the power supply energy and the decoded signal to match the load 20 .

[0090] In this embodiment, the conversion module 32 can process the time-divided or energy-divided energy or signal, and the control sub-module 323 can adjust the energy power output by the conversion module 32 or the power of the decoded signal, so as to finally match the energy and signal with the load, thereby achieving the effect of providing power supply energy to the load and communicating with the load.

[0093] The power distribution unit 3212 is used to perform power distribution operations on the power supply energy greater than or equal to the first ratio and output it to the energy storage unit 3213.

[0094] In this embodiment, the received energy can be subjected to power distribution and energy storage processing, and an adaptive energy signal can be provided to the rectifier and filter sub-module 324 to facilitate subsequent processing by the rectifier and filter sub-module 324, which is beneficial to improving energy conversion efficiency.

The load 20 may be selected according to specific scenarios, and the corresponding solutions fall within the protection scope of the present disclosure.

[0111] based on Figures 1 to 9 The inventive concept of the electronic device shown in the figure, the embodiment of the present disclosure provides an electronic device, Fig.10 The schematic diagram of the electronic device is illustrated. Fig.11 This example shows a functional block diagram of an electronic device. Fig.10 and Fig.11 , an electronic device, comprising: an antenna module, a time division sub-module, a power division sub-module, a signal decoding sub-module, a conversion module, a charging protection module and a load module.

[0112] The antenna module receives the radio frequency signal and transmits it to the time division sub-module and the power division sub-module.

[0113] The time division submodule can divide each time slot period into a first time slot and a second time slot by using a time division (TS) method in the time dimension. Assuming the time slot period is T, the first time slot is τ, and the second time slot is T-τ, the division method of the time slot period T is as follows: Fig.12 shown.

[0114] The first switching switch K1 switches to the first switching state in the first time slot, at which time the RF signal can enter the energy collection unit Xp(t), and switches to the second switching state in the second time slot, at which time the RF signal can enter the signal receiving unit XI(t). The energy detection control unit can detect the energy ratio ρ to perform power splitting (PS) on the energy. When the energy ratio is ρ, the second switching switch switches to the first switching state, and the millimeter wave of ρP (0≤ρ≤1) sends wireless energy to the rectifier and filter sub-module; when the energy ratio is 1-ρ, the second switching switch K2 switches to the second switching state, and the millimeter wave of (1-ρ)P is used for information decoding and then sent to the rectifier and filter sub-module. When the first switching switch switches to the second switching state, the information receiving unit uses the received wireless energy to send RF information to the antenna module.

[0115] Among them, the energy detection control unit can adjust the transmission power and link gain according to the load information provided by the load, and determine the energy ratio ρ while ensuring that the antenna signal is not interfered with and the energy and signal of the load are dynamically balanced. For details, please refer to the relevant technology and will not be repeated here.

[0116] When the second switch is switched to the first switch state, the energy collector unit can collect energy, and the power distribution unit distributes the energy and stores it in the storage unit. When the second switch is switched to the second switch state, the signal receiving unit receives the initial signal in the radio frequency signal, amplifies it by the signal amplifying unit to obtain an amplified signal, and demodulates the amplified signal by the signal demodulating unit to obtain a communication signal.

[0117] The controller submodule can obtain the above communication signal to control the energy collector unit and the signal receiving unit, and adjust the output of the energy conversion submodule and the signal conversion submodule through feedback control.

[0118] The rectifier and filter submodule is used to rectify and filter the power supply energy and the decoded signal. The energy is first input filtered, then low-pass filtered after passing through an impedance matching network and a radio frequency DC circuit, and then output to the charging protection module through an output unit.

[0119] The charging protection module can transmit the rectified and filtered wireless RF energy to the load for power supply, and is used to control and protect the charging power circuit, and sends feedback signals to the energy collector unit to control wireless charging.

[0120] In this embodiment, Fig.11 The electronic equipment shown in the example is simulated and analyzed, and the Fig.13 and Fig.14 An example performance comparison is shown in the graph. Fig.13 In single-user mode, under the mixed time-splitting and power-splitting mode (curve 3), the maximum collected energy of the load of the disclosed solution is 1000mW, while the maximum collected energy of the power-splitting (curve 1) and time-splitting (curve 2) solutions in the related art is 400mW. Fig.14 In the multi-user mode, when the time division and power division mixed division (curve 3) is adopted, the maximum collected energy of the load of the disclosed scheme is about 200mW, while the maximum collected energy of the power division (curve 1) and time division (curve 2) schemes in the related art is 150mW.
