[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0024] Embodiment 1

[0025] The embodiment of the present application provides a protective shell of a terminal, Figure 1 A schematic diagram of the structure of an optional terminal protective shell provided in an embodiment of the present application, such as Figure 1 As shown, the protective shell of the terminal may include: a power management chip 11, a wireless reverse charging coil 12, a wireless charging processing module 13, a first communication coil 14, a first communication processing module 15 and a switch element 16; wherein,

[0026] The two terminals of the first communication coil 14 are respectively connected to the two input terminals of the first communication processing module 15, the output terminal of the first communication processing module 15 is connected to the power management chip 11, the switch element 16 is arranged between at least one terminal of the wireless reverse charging coil 12 and the wireless charging processing module 13, and the control terminal of the switch element 16 is connected to the power management chip 11;

[0027] The first communication coil 14 is used to: receive an AC signal through a first communication protocol;

[0028] The first communication processing module 15 is used to: process the AC signal to obtain a DC signal;

[0029] The power management chip 11 is used to: after receiving the DC signal, output a control signal to the control end of the switch element 16 to control the switch element 16 to be in a connected state to supply power to the protective shell.

[0030] Specifically, generally, the terminal is provided with a first communication coil. Since the first communication coil has a small area, in practical applications, it can be arranged in some spaces with little impact or irregular spaces. Since the transmission energy is small due to the short distance, the impact is not great.

[0031] In order to realize communication between the terminal and the protective shell through the first communication protocol, a first communication coil 14 is arranged at a position corresponding to the first communication coil of the protective shell and the terminal. Here, when the terminal triggers the need to use the UWB function through the protective shell, the terminal sends a signal to the first communication coil 14 of the protective shell through its own first communication coil, so that the first communication coil 14 receives the AC signal through the first communication protocol. After receiving the AC signal, the first communication processing module 15 processes the AC signal, for example, matching processing and rectification and filtering processing are performed to obtain a DC signal, so that after receiving the DC signal, the power management chip 11 outputs a control signal to the control end of the switch element 16 to control the switch element 16 to be in a connected state, thereby powering the protective shell and enabling the terminal to use the UWB function of the protective shell.

[0032] In order to realize wireless reverse charging of the protective case, in an optional embodiment, the wireless charging processing module may include: a wireless charging chip, a rectifier circuit and a filter circuit; wherein,

[0033] The input end of the wireless charging chip is connected to the switch element 16 , the output end of the wireless charging chip is connected to the input end of the rectifier circuit, the output end of the rectifier circuit is connected to the input end of the filter circuit, and the output end of the filter circuit is connected to the power management chip 11 .

[0034] That is to say, when the terminal performs wireless reverse charging on the protective shell, the switch element 16 connects the wireless reverse charging chip with the wireless charging chip, and charges the power management chip 11 through the wireless charging chip, the rectifier circuit and the filter circuit.

[0035] In order to realize the control of the wireless reverse charging function in the protective shell, in an optional embodiment, the first communication processing module 15 may include: a matching circuit and a rectifying and filtering circuit; wherein,

[0036] The two input ends of the matching circuit are respectively connected to the two connection terminals of the first communication coil 14, the output end of the matching circuit is connected to the input end of the rectifying and filtering circuit, and the output end of the rectifying and filtering circuit is connected to the power management chip 11;

[0037] The matching circuit is used to: perform matching processing on the AC signal to obtain a matched AC signal;

[0038] The rectifier and filter circuit is used to rectify and filter the matched AC signal to obtain a DC signal.

[0039] The matching circuit performs matching processing on the AC signal, which may specifically include impedance matching, inductive reactance matching and capacitive reactance matching, so as to adjust the matching between the first communication coil 14 and the rectification and filtering circuit, thereby obtaining a matched AC signal.

[0040] The matching circuit is used to perform matching processing on the AC signal. In practical applications, it can be a π-type network for adjusting the radio frequency performance of the signal.

[0041] In addition, the rectifier and filter circuit rectifies and filters the matched AC signal to obtain a DC signal. After receiving the DC signal from the rectifier and filter circuit, the power management chip 11 outputs a control signal to the control end of the switch element 16. The control signal controls the switch element 16 to be in a connected state. When the switch element 16 is in a connected state, the wireless reverse charging coil 12 is connected to the wireless charging processing module 13. Then, the terminal reverse charges the protective shell through its own wireless reverse charging coil and the wireless reverse charging coil 12 on the protective shell, so that the power management chip 11 of the protective shell can power the protective shell.

[0042] In actual applications, taking the terminal as a mobile phone and the protective shell of the terminal as a mobile phone shell as an example, when the mobile phone triggers the UWB function that needs to use the mobile phone shell, the mobile phone sends a first communication protocol signal to the first communication coil 14 of the mobile phone shell through its own first communication coil 14. After the first communication coil 14 on the mobile phone shell receives the first communication protocol signal from the mobile phone, the matching circuit performs impedance, capacitive reactance and inductive reactance matching processing on the first communication protocol signal. The rectification and filtering circuit obtains a small amount of energy from the first communication coil 14 for rectification and filtering, and then sends the rectified and filtered signal to the power management chip 11. The power management chip 11 enables the switch element 16 to be closed, so that the branch of the wireless reverse charging coil 12 and the wireless charging processing module 13 are in a connected state.

[0043] After the switch element 16 is closed, the wireless reverse charging coil 12 starts to work normally. After the wireless reverse charging energy is voltage-adjusted by the power management chip 11, it starts to power the MCU\UWB module of the mobile phone case, so that the MCU\UWB module of the mobile phone case starts to work normally.

[0044] Here, it should be noted that because the UWB module in the mobile phone case requires a large power consumption, the first communication coil 14 is small and the power supply capacity after rectification is limited and insufficient to support the normal operation of the UWB module, so the wireless reverse charging coil 12 needs to be powered normally before the UWB module can be turned on.

[0045] In addition to being able to trigger the power management chip 11 to close the switch element 16, the first communication coil 14 can also stop the terminal from wirelessly charging the protective case when the terminal does not need to use the UWB function of the protective case. In an optional embodiment, the protective case further includes: an MCU; wherein,

[0046] The MCU is used to send a control signal to the control end of the switch element 16 to control the switch element 16 to be in an off state.

[0047] Specifically, the control end of the switch element 16 is also connected to the MCU of the protective case. In this way, when the MCU receives a notification of the wireless reverse charging stop instruction through the Bluetooth module of the mobile phone case, the MCU controls the switch element 16 to be in an off state. At this time, the wireless reverse charging coil 12 of the protective case and the wireless charging processing module 13 of the protective case are in a disconnected state, so the terminal cannot perform wireless reverse charging to the protective case. In this way, the MCU controls the switch element 16 to stop the terminal from performing wireless reverse charging to the protective case. Stopping the wireless reverse charging to the protective case in a timely manner is beneficial to other third-party devices and the terminal to perform reverse charging through the wireless reverse charging coil 12.

[0048] In order to expand the use range of the first communication coil 14, in an optional embodiment, the first communication processing module 15 further includes: a first communication protocol chip; wherein,

[0049] The input end of the first communication protocol chip is connected to the output end of the matching circuit, and the output end of the first communication protocol chip is connected to the MCU;

[0050] The first communication protocol chip is used to receive data received from the first communication coil 14 from the matching circuit, and transmit the data to the MCU.

[0051] That is to say, a first communication protocol chip is added to the protective shell, and the first communication protocol chip is connected between the output end of the matching circuit and the MCU, so that the terminal can send data to the protective shell through its own first communication coil 14, the first communication coil 14 of the protective shell receives the data, and transmits the data to the MCU through the matching circuit and the first communication protocol chip, so that the protective shell can not only send and receive data through the Bluetooth module, but also send and receive data through the branch formed by the first communication coil 14, the matching circuit and the first communication protocol chip, that is, the protective shell is provided with another communication link for data transmission and reception, which is conducive to data interaction between the terminal and the protective shell.

[0052] In order to switch the switch element 16 in a timely manner so that the branch is in a connected state or a disconnected state, in an optional embodiment, the switch element is an antenna switch; wherein,

[0053] The control end of the antenna switch is connected to the power management chip 11, one connection end of the antenna switch is connected to at least one connection terminal of the wireless reverse charging coil 12, and the other connection end of the antenna switch is connected to the input end of the wireless charging processing module 13;

[0054] The antenna switch tube is used to: receive the control signal of the power management chip 11 and be in a connected state so that the wireless reverse charging coil 12 and the wireless charging processing module 13 are in a connected state.

[0055] Specifically, an antenna switch is used as a switching element 16 and is arranged between the wireless reverse charging coil 12 and the wireless charging processing module 13. Then, the antenna switch can be placed in a connected state through a control signal generated by the power management chip 11, so that the two connection terminals of the wireless reverse charging coil 12 form a path with the wireless charging processing module 13 to power the power management chip 11 of the protective shell.

[0056] After receiving the DC signal, the power management chip 11 generates a control signal and applies it to the control end of the antenna switch, so that the antenna switch is in a connected state.

[0057] In order to disconnect the wireless reverse charging in time to improve the utilization rate of the wireless reverse charging function of the terminal, in an optional embodiment, the control end of the antenna switch is connected to the MCU; wherein,

[0058] The antenna switch is also used to: receive a control signal from the MCU and be in a disconnected state so that the wireless reverse charging coil 12 and the wireless charging processing module 13 are in a disconnected state.

[0059] That is to say, when the terminal determines that the UWB function of the protective case is not needed, the terminal can send a stop reverse charging instruction to the MCU through the first communication coil 14, and can also send a stop reverse charging instruction to the MCU through the Bluetooth module of the protective case. In this way, when the MCU receives the stop reverse charging instruction, it generates a control signal to control the antenna switch to be in the disconnected state.

[0060] Wherein, the protective shell further includes a second communication module, and the second communication module is at least one of a Bluetooth module and a Wireless Fidelity (WiFi) module.

[0061] Specifically, in addition to the UWB module, the protective case may also include a Bluetooth module and / or a WiFi module. In this way, after the protective case uses the UWB module to obtain the angle information, the protective case can transmit the angle information to the terminal through the Bluetooth module, and can also establish a connection with the terminal through the WiFi module to transmit the angle information.

[0062] For the protective case with UWB function, in an optional embodiment, the protective case also includes a UWB module, the UWB module is connected to the MCU, based on the switch element being in a connected state, the wireless reverse charging coil receives AC power, which is converted into rectified power by the wireless charging processing module to power the UWB module.

[0063] Specifically, in order to use the UWB function, a UWB module is provided in the protective shell, and the UWB module is connected to the MCU. When the switching element is in the connected state, the terminal receives AC power through the wireless reverse charging coil of the protective shell, and the wireless charging processing module converts the AC power to obtain a rectified power supply. The rectified power supply is used to charge the power management chip, so that the power management chip powers the UWB module to realize the UWB function of the protective shell.

[0064] The protective shell of the terminal described in one or more of the above embodiments is described below with examples.

[0065] Figure 2 A schematic diagram of an example of a protective shell of an optional terminal provided in an embodiment of the present application, such as Figure 2 As shown, the protective shell of the terminal may include: a private protocol communication coil 21 (equivalent to the above-mentioned first communication coil), a matching circuit 22, a rectifying and filtering circuit 23, a private protocol chip 24 (equivalent to the above-mentioned first communication protocol chip), a wireless reverse charging coil 25, a switching switch 26, a wireless charging chip and rectifying and filtering 27, a power management chip 28, a main control MCU 29, a UWB module 210 and a Bluetooth module 211; wherein,

[0066] The two connection terminals of the private protocol communication coil 21 are respectively connected to the two input ends of the matching circuit 22, the output end of the matching circuit 22 is respectively connected to the input end of the rectifying and filtering circuit 23 and the input end of the private protocol chip 24, the output end of the rectifying and filtering circuit 23 is connected to an input end of the power management chip 28, the output end of the private protocol chip 24 is connected to the input end of the main control MCU 29, one connection end of the wireless reverse charging coil 25 is connected to a connection end of the switching switch 26, the other connection end of the wireless reverse charging coil 25 is connected to an input end of the wireless charging chip and the rectifying and filtering circuit 27, the control end of the switching switch 26 is connected to an output end of the power management chip 28, the other connection end of the switching switch 26 is connected to another input end of the wireless charging chip and the rectifying and filtering circuit 27, the output end of the wireless charging chip and the rectifying and filtering circuit 27 is connected to another input end of the power management chip 28, the other output end of the power management chip 28 is connected to the main control MCU 29, and the output end of the main control MCU 29 is respectively connected to the Bluetooth module 211, the UWB module 210 and the switching switch 26.

[0067] It should be noted that the private protocol communication coil 21 and its subsequent circuits or modules: the switching switch 26 is turned on when the function is started, and the main control MCU29 communicates data with the mobile phone when necessary, and the switching switch 26: controls the switch of the wireless reverse charging coil 25; the main control MCU29 can use the private protocol communication coil 21 to communicate with the mobile phone in a manner similar to the NFC chip; the matching circuit 22 is a conventional matching circuit, including but not limited to a π-type network, etc., in order to adjust the RF performance.

[0068] When the mobile phone triggers the need to use the UWB function, the mobile phone sends protocol information to the private protocol coil 21 of the protective shell through the private protocol communication coil. After the private protocol communication coil 21 on the protective shell receives the private protocol signal from the mobile phone, the rectified current will first obtain a small amount of energy from the coil for rectification and filtering, and then pass through the power management chip 28 to power the switching switch 26 and enable the switching switch 28 to close the wireless reverse charging coil 25. After the switching switch 26 is closed, the wireless reverse charging starts to work normally. After the wireless reverse charging energy is adjusted in voltage by the power management chip 28, the MCU\UWB and other normal startups begin.

[0069] Because the UWB module requires a large amount of power consumption, the private protocol communication coil is small and the power supply capacity after rectification is limited and insufficient to support the normal operation of the UWB module, wireless reverse charging is required to power the module normally before the UWB module can be turned on.

[0070] If the mobile phone does not need to use the UWB function, the mobile phone notifies the main control MCU 29 of the protective shell through the Bluetooth module or the private protocol communication coil 21, the matching circuit 22 and the private protocol chip 24, and the protective shell starts to actively send instructions to the switch 26 through the main control MCU 29, so that the switch 26 disconnects the wireless charging coil 25, and the wireless reverse charging function is turned off. After the power is off, the switch is reset, and the wireless reverse charging coil 25 of the protective shell remains in the coil disconnected state. At this time, if the mobile phone supplies power to an external third-party device, or the wireless charger charges the mobile phone wirelessly, it can proceed normally.

[0071] An embodiment of the present application provides a protective shell of a terminal, which includes: a power management chip, a wireless reverse charging coil, a wireless charging processing module, a first communication coil, a first communication processing module and a switching element, wherein the two wiring terminals of the first communication coil are respectively connected to the two input terminals of the first communication processing module, the output terminal of the first communication processing module is connected to the power management chip, the switching element is arranged between at least one wiring terminal of the wireless reverse charging coil and the wireless charging processing module, the control end of the switching element is connected to the power management chip of the protective shell, the first communication coil is used to: receive an AC signal through a first communication protocol, the first communication processing module is used to: process the AC signal to obtain a DC signal, and the power management chip is used to: after receiving the DC signal, output a control signal to the control end of the switching element to control the switching element to be connected state, powering the protective shell; that is, in an embodiment of the present application, a first communication coil, a first communication processing module and a switching element are added to the protective shell, so that when the terminal needs to use a function of the protective shell, for example, the UWB function, the protective shell can receive an AC signal through the first communication coil, and then process the AC signal, so that after receiving the obtained DC signal, the power management chip outputs a control signal to the switching element to control the switching element to be in a connected state. In this way, when the terminal needs to use the UWB function of the protective shell, the terminal can accurately turn on the reverse charging of the protective shell by the terminal, thereby preventing the terminal from unconsciously turning on the UWB function and causing the terminal to perform unnecessary wireless reverse charging of the protective shell, thereby avoiding conflicts between the mobile phone case with UWB function and the terminal using the wireless reverse charging coil to communicate during wireless reverse charging.

[0072] Embodiment 2

[0073] The embodiment of the present application provides a control method, which is applied to a protective shell of an upper terminal, wherein the protective shell of the terminal includes: a power management chip, a wireless reverse charging coil, a wireless charging processing module, a first communication coil, a first communication processing module and a switch element; wherein two wiring terminals of the first communication coil are respectively connected to two input terminals of the first communication processing module, an output terminal of the first communication processing module is connected to the power management chip, the switch element is arranged between at least one wiring terminal of the wireless reverse charging coil and the wireless charging processing module, and a control terminal of the switch element is connected to the power management chip, Figure 3 A flow chart of an optional control method provided in an embodiment of the present application is as follows: Figure 3 As shown, including:

[0074] S301: When the terminal is reversely charging the protective case, a stop reverse charging instruction is received from the terminal through the first communication coil;

[0075] S302: generating a control signal according to the reverse charging stop instruction;

[0076] Specifically, based on the protective shell of the terminal described in the first embodiment, when the terminal is reversely charging the protective shell, the first communication coil receives a stop reverse charging instruction from the terminal. Figure 2 For example, a stop reverse charging instruction is received through the first communication coil and transmitted to the main control MCU through the matching circuit and the first communication protocol chip. The main control MCU generates a control signal according to the received stop reverse charging instruction, wherein the control signal is used to control the switch element to be in an off state.

[0077] In this way, through the newly added first communication coil, the matching circuit and the branch formed by the first communication protocol chip, the protective shell can not only transmit the stop reverse charging instruction to the terminal through the Bluetooth module, but also transmit the stop reverse charging instruction to the terminal through the first communication coil, so that the protective shell can promptly know whether the terminal needs to use the UWB function of the protective shell.

[0078] In order to more conveniently transmit data between the terminal and the protective shell, in an optional embodiment, the method further includes:

[0079] When the terminal charges the protective case, the first communication coil receives data from the terminal.

[0080] or,

[0081] When the terminal is reversely charging the protective case, data is sent to the terminal through the first communication coil.

[0082] In practical applications, Figure 2 For example, when the terminal charges the protective case, data from the terminal is received through the first communication coil, and is transmitted to the main control MCU through the matching circuit and the first communication protocol chip, so that the main control MCU receives the data. Alternatively, when the terminal charges the protective case reversely, data can also be sent to the terminal through the first communication coil. For example, the calculated UWB angle information can be sent to the terminal through the first communication coil of the preset communication protocol.

[0083] In this way, through the branch formed by the newly added first communication coil, the matching circuit and the first communication protocol chip, the protective shell can not only transmit data to the terminal through the Bluetooth module, but also transmit data to the terminal through the first communication coil, so that the protective shell and the terminal can use any communication link for data communication.

[0084] The control method described in one or more of the above embodiments is described below with examples.

[0085] Or Figure 3 Taking the structure of the protective shell of the terminal as an example, Figure 4 A schematic diagram of the structure of an example of another optional terminal protective shell provided in an embodiment of the present application, such as Figure 4 As shown, a wireless reverse charging coil is arranged inside the protective shell, wherein the wireless reverse charging coil corresponds to the position of the wireless reverse charging coil of the mobile phone. The interior of the protective shell of the terminal also includes a private protocol communication coil, which can be placed at any position where there is space in the mobile phone, but it also needs to correspond to the position of the private protocol communication coil of the mobile phone.

[0086] Based on the above Figure 3 and Figure 4 , Figure 5 A flow chart of an example of an optional control method provided in an embodiment of the present application is as follows: Figure 5 As shown, the method may include:

[0087] S501: The mobile phone determines whether the UWB function is triggered by the mobile phone; if yes, execute S502; if no, execute S501;

[0088] S502: The mobile phone receives a signal via a private protocol communication coil;

[0089] S503: The protective shell processes the received signal to control the switch to close;

[0090] Specifically, the protective case performs matching processing and rectification filtering on the received signal, so that the power management chip controls the switch element to close, thus realizing wireless reverse charging of the mobile phone to the protective case;

[0091] In addition, if a third-party device is wirelessly reverse charged or a wireless charger is used for wireless charging, the private protocol communication coil on the mobile phone does not work, the private protocol communication coil on the protective case has no induced current, and the power management chip cannot be powered on. Therefore, the wireless reverse charging coil of the protective case remains disconnected and not closed, which does not affect the normal positive and reverse charging status of the mobile phone for other devices.

[0092] S504: The protective case establishes a connection with the terminal through a Bluetooth module or a private protocol communication coil, and transmits the UWB data to the mobile phone;

[0093] Specifically, after the wireless reverse charging works normally, the MCU, UWB module and Bluetooth module operate normally, and the protective case can actively connect and communicate with the mobile phone (communication with the mobile phone can be through Bluetooth or through a private protocol communication coil); the protective case can thus determine which UWB data the mobile phone needs to obtain; then the protective case will obtain the UWB data from the UWB module and transmit it to the mobile phone so that the mobile phone can perform direction finding and positioning.

[0094] If the mobile phone triggers the UWB function requirement by mistake, the protective case will not receive the corresponding UWB data after power-on, and then the MCU on the protective case will notify the mobile phone and actively turn off the switch. The protective case needs to be used in conjunction with the UWB tag. In the home scene, the tag needs to be bound to the home appliance for convenient control, and it cannot be used outside the scene; therefore, the false trigger can be judged based on whether the UWB tag signal is received after the mobile phone turns on UWB.

[0095] S505: The mobile phone obtains and processes UWB data;
