[0035] Combine the following Figures 1 to 5 An accessory of an electronic device, an electronic device, a control method of an electronic device, and a storage medium according to embodiments of the present application are described.

[0036] In some embodiments of the present application, an accessory 200 of an electronic device is provided. The electronic device 100 includes a near field communication coil 104 and a first identification element 106. Figure 1 FIG. 1 shows one of the structural schematic diagrams of an accessory 200 of an electronic device and an electronic device 100 according to an embodiment of the present application. Figure 2 FIG. 2 shows a second structural diagram of an accessory of an electronic device and an electronic device according to an embodiment of the present application. Figure 1 and Figure 2 As shown, the accessory 200 of the electronic device includes:

[0037] The receiving portion 202, at least a portion of the receiving portion 202 is in contact with the electronic device 100;

[0038] The coupling coil 204 is disposed in the accommodating portion 202 . When the accommodating portion 202 and the electronic device 100 are in close contact with each other, the coupling coil 204 is coupled to the near field communication coil 104 .

[0039] The second identification component 206 is disposed in the accommodating portion 202 and connected to the coupling coil 204. When the coupling coil 204 is coupled to the near field communication coil 104, the second identification component 206 is used to form an identification signal with the first identification component 106. The electronic device 100 determines the fitting state of the accessory electronic device 100 based on the identification signal.

[0040] In the embodiment of the present application, the electronic device 100 may be an electronic device 100 such as a mobile phone, a tablet computer, etc., and the electronic device 100 is provided with a near field communication coil 104 and a first identification element 106 .

[0041] The accessory 200 of the electronic device can be a protective case or protective cover for a mobile phone or tablet computer, such as a mobile phone case, a leather case, a mobile phone holder, etc. The accessory 200 of the electronic device is provided with a receiving portion 202, and the shape of the receiving portion 202 matches the shape of the electronic device 100. Taking the example that the accessory 200 of the electronic device is a mobile phone leather case, when the mobile phone leather case is attached to the mobile phone, the back panel of the mobile phone fits with the receiving portion 202.

[0042] Among them, a coupling coil 204 is arranged on the accommodating portion 202. When the mobile phone leather case is attached to the mobile phone, the positions of the near field communication coil 104 and the coupling coil 204 are relative. At this time, the near field communication coil 104 and the coupling coil 204 are coupled with each other and can transmit NFC signals.

[0043] At the same time, a first identification component 106 is also provided on the mobile phone, and a second identification component 206 is provided on the accommodating portion 202 . After the mobile phone leather case is attached to the mobile phone, a signal loop can be formed between the first identification component 106 and the second identification component 206 .

[0044] Among them, the near field communication coil 104 set on the electronic device 100 such as a mobile phone is generally used to communicate with an external card reader or card through a short-range antenna field, so as to simulate the functions of an access card, a bus card, and a subway card. During the operation of the mobile phone, the NFC function of the mobile phone will transmit a field strength signal with a frequency of 13.56MHz through the near field communication coil 104 when it is in standby or working.

[0045] After the mobile phone leather case is attached to the mobile phone, the coupling coil 204 can receive the field strength signal emitted by the near field communication coil 104 and induce a corresponding 13.56MHz AC signal. The AC signal is transmitted to the second identification element 206, and forms an identification signal on the first identification element 106 through the signal loop between the second identification element 206 and the first identification element 106.

[0046] When the mobile phone or other electronic device 100 collects the identification signal, it can be determined based on the signal strength of the identification signal that the leather case has been attached to the mobile phone, thereby achieving accurate attachment detection.

[0047] The embodiment of the present application couples the NFC coil of the housing-type accessory with the NFC coil in the electronic device 100 such as the mobile phone to generate a coupling signal of a specific frequency, and identifies the identification signal of the fit of the leather case, mobile phone case, etc. through the identification piece, does not rely on the detection signal of the sensor with poor anti-interference ability such as the Hall sensor, and improves the reliability of the fit detection of the mobile phone case and mobile phone cover.

[0048] In some embodiments of the present application, Figure 1 and Figure 2 As shown, the first identification member 106 includes a first metal sheet 1062 and a second metal sheet 1064;

[0049] The second identification member 206 includes a third metal sheet 2062 and a fourth metal sheet 2064. The third metal sheet 2062 is connected to the first end of the coupling coil 204, and the fourth metal sheet 2064 is connected to the second end of the coupling coil 204. When the accommodating portion 202 is in contact with the electronic device 100, the position of the first metal sheet 1062 is opposite to the position of the third metal sheet 2062, and the position of the second metal sheet 1064 is opposite to the position of the fourth metal sheet 2064.

[0050] In the embodiment of the present application, the first identification member 106 and the second identification member 206 are both configured as a pair of metal sheets. Specifically, the first identification member 106 includes a first metal sheet 1062 and a second metal sheet 1064, and the second identification member 206 includes a third metal sheet 2062 and a fourth metal sheet 2064. After the mobile phone leather case is attached to the mobile phone, the first metal sheet 1062 and the third metal sheet 2062 are positioned opposite to each other, forming a capacitance effect therebetween, and the second metal sheet 1064 and the fourth metal sheet 2064 are positioned opposite to each other, forming a capacitance effect therebetween as well.

[0051] At the same time, the third metal sheet 2062 and the fourth metal sheet 2064 form a loop inside the mobile phone, so the coupling signal generated on the coupling coil 204 can be transmitted to the first metal sheet 1062 and the second metal sheet 1064 inside the mobile phone through the capacitive effect between the metal sheets. Therefore, when the mobile phone NFC transmits a field strength signal with a frequency of 13.56 MHz through the near field communication coil 104, when the mobile phone leather case is attached, the mobile phone can detect the identification signal of the same frequency on the first identification piece 106, thereby achieving accurate fitting detection.

[0052] By setting up a loop through the capacitive coupling effect of metal sheets, the fitting state of holsters and other containing accessories can be detected, achieving high-precision, highly anti-interference fitting detection at a low cost.

[0053] In some embodiments of the present application, the electronic device 100 includes a radio frequency antenna;

[0054] The accessory 200 of the electronic device further includes:

[0055] A frequency selection circuit 2066, the input end of which is connected to the coupling coil 204, for selecting the frequency of the coupling signal on the coupling coil 204;

[0056] The transmitting antenna 2068 is connected to the output end of the frequency selection circuit 2066, and is used to send an identification signal to the radio frequency antenna based on the frequency-selected coupling signal when the coupling coil 204 is coupled with the near field communication coil 104.

[0057] In the embodiments of the present application, Figure 3 The third structural diagram of the accessory 200 of the electronic device and the electronic device 100 according to the embodiment of the present application is shown. Figure 4 FIG. 4 shows a fourth structural diagram of an accessory 200 of an electronic device and an electronic device 100 according to an embodiment of the present application. Figure 3 and Figure 4 As shown, the electronic device 100 includes a radio frequency antenna, and the accessory 200 for the electronic device includes a transmitting antenna 2068 .

[0058] Specifically, the radio frequency antenna of the electronic device 100 is specifically a signal antenna of a mobile phone. The radio frequency antenna can be an antenna provided by the mobile phone itself, such as an LTE radio frequency antenna, a 5G radio frequency antenna or a Wi-Fi radio frequency antenna.

[0059] The transmitting antenna 2068 is connected to the coupling coil 204 through the frequency selection circuit 2066, wherein the near field communication coil 104 on the mobile phone end will transmit a field strength signal at a fixed frequency, such as a field strength signal with a transmitting frequency of 13.56 MHz. The field strength signal will generate a coupling signal on the coupling coil 204, and the coupling signal may be mixed with some signals coupled from the ambient space.

[0060] Through the frequency selection circuit 2066, signals other than the fixed frequency field strength signal emitted by the near field communication coil 104 can be filtered out, and only the coupled signal with a frequency of 13.56 MHz emitted by the near field communication coil 104 is retained, and the coupled signal is transmitted to the transmitting antenna 2068, and the identification signal of the corresponding frequency is transmitted to the radio frequency antenna of the mobile phone through the transmitting antenna 2068.

[0061] After the radio frequency antenna of the mobile phone receives the identification signal, it can determine whether the leather case is attached to the mobile phone based on the signal strength of the identification signal.

[0062] The embodiment of the present application reuses the RF antenna of the mobile phone and sets a transmitting antenna 2068 on a holster or other storage accessory to transmit an identification signal to the RF antenna, thereby achieving accurate detection of the fitting status of the holster without adding additional identification devices to the mobile phone.

[0063] In some embodiments of the present application, the frequency selection circuit 2066 includes: an inductive element 20662 connected to the coupling coil 204; and a first capacitive element 20664 connected in parallel to the inductive element 20662.

[0064] In the embodiment of the present application, the frequency selection circuit 2066 includes an inductive element 20662 and a capacitive element 20664, such as Figure 4 As shown, the two ends of the inductive element 20662 are respectively connected to the two ends of the coil, and the capacitive element 20664 is arranged in parallel with the inductive element 20662. By adjusting the electrical parameters of the inductive element 20662 and the capacitive element 20664, the frequency selection circuit 2066 can only allow coupling signals of a specific frequency to pass through, thereby avoiding affecting the performance of the mobile phone communication antenna.

[0065] In some embodiments of the present application, an electronic device 100 is provided, such as Figure 1 and Figure 2 As shown, the electronic device 100 includes: a housing 102, one side of which can be fitted with the accessory 200 of the electronic device provided in any of the above embodiments;

[0066] A near field communication coil 104 is disposed in the housing 102;

[0067] The first identification element 106 is connected to the near field communication coil 104 and is used to detect the identification signal of the second identification element 206 when the near field communication coil 104 is coupled with the coupling coil 204, wherein the accessory 200 of the electronic device includes the coupling coil 204 and the second identification element 206;

[0068] The detection module 108 is connected to the first identification component 106 and is used to determine the fitting state of the electronic device accessory 200 and the electronic device 100 according to the identification signal.

[0069] In an embodiment of the present application, the electronic device 100 includes a shell 102, a first near-field communication and a first identification element 106, wherein the electronic device 100 can be an electronic device 100 such as a mobile phone, a tablet computer, etc., and the near-field communication coil 104 is a coil used by the mobile phone to implement the NFC function, which is specifically used to communicate with an external card reader or card through a short-range antenna field, thereby being able to simulate the functions of an access card, a bus card, and a subway card.

[0070] When the mobile phone is in operation, the NFC function of the mobile phone will transmit a field strength signal with a frequency of 13.56 MHz through the near field communication coil 104 when it is in standby or working.

[0071] Specifically, when a mobile phone leather case or other containing accessories is attached to the mobile phone, the coupling coil 204 provided on the leather case is coupled with the near field communication coil 104 , and at this time, a coupling signal of 13.56 MHz is coupled to the coupling coil 204 .

[0072] This part of the coupling signal is transmitted to the second identification element 206 provided on the leather case, and forms an identification signal on the first identification element 106 through the signal loop between the second identification element 206 and the first identification element 106. When the mobile phone detects the identification signal on the first identification element 106, it is determined that the accessory 200 of the electronic device such as the leather case is attached to the mobile phone. At this time, according to the preset rules, the system theme can be adjusted to a theme matching the attached leather case, or the small screen display function can be turned on.

[0073] The embodiment of the present application couples the NFC coil of the housing-type accessory with the NFC coil in the electronic device 100 such as the mobile phone to generate a coupling signal of a specific frequency, and identifies the identification signal of the fit of the leather case, mobile phone case, etc. through the identification piece, does not rely on the detection signal of the sensor with poor anti-interference ability such as the Hall sensor, and improves the reliability of the fit detection of the mobile phone case and mobile phone cover.

[0074] In some embodiments of the present application, the first identification element 106 includes a first metal sheet 1062, a second metal sheet 1064, and a second capacitive element, wherein a first end of the second capacitive element is connected to the first metal sheet 1062, and a second end of the second capacitive element is connected to the second metal sheet 1064;

[0075] The detection module 108 includes a frequency selection acquisition module 1082, and the frequency selection acquisition module 1082 is connected in parallel with the second capacitive element;

[0076] The second identification component 206 includes a third metal sheet 2062 and a fourth metal sheet 2064. When the fitting state is mutually fitted, the position of the first metal sheet 1062 is opposite to the position of the third metal sheet 2062, and the position of the second metal sheet 1064 is opposite to the position of the fourth metal sheet 2064. A loop capable of transmitting the coupling signal between the near field communication coil 104 and the coupling coil 204 is formed between the third metal sheet 2062, the first metal sheet 1062, the second capacitive element, the second metal sheet 1064 and the fourth metal sheet 2064, so that the frequency selection acquisition module 1082 can obtain the coupling signal through the second capacitive element, and perform frequency selection processing on the coupling signal to obtain an identification signal.

[0077] In the embodiment of the present application, a third metal sheet 2062, a fourth metal sheet 2064 and a second capacitive element 2066 are arranged on the electronic device 100 such as a mobile phone as the second identification element 206. The arrangement positions of the third metal sheet 2062 and the fourth metal sheet 2064 are associated with the arrangement positions of the accommodating accessories such as a leather case.

[0078] The detection module 108 includes a frequency selection acquisition module 1082, which is connected in parallel with the second capacitive element, so that it can collect the coupled signal through the signals at both ends of the second capacitive element and perform frequency selection on the coupled signal, such as selecting the identification signal with a frequency of 13.56 MHz in the coupled signal.

[0079] Specifically, after the mobile phone leather case is attached to the mobile phone, the first metal sheet 1062 and the third metal sheet 2062 are opposite to each other, forming a capacitance effect therebetween, and the second metal sheet 1064 and the fourth metal sheet 2064 are opposite to each other, forming a capacitance effect therebetween as well.

[0080] At this time, a loop capable of transmitting the coupling signal between the near field communication coil 104 and the coupling coil 204 is formed between the third metal sheet 2062, the first metal sheet 1062, the second capacitive element, the second metal sheet 1064 and the fourth metal sheet 2064. Therefore, the coupling signal generated on the coupling coil 204 can be transmitted to the first metal sheet 1062 and the second metal sheet 1064 inside the mobile phone through the capacitive effect between the metal sheets. At this time, the frequency selection acquisition module 1082 performs frequency selection according to the collected coupling signal at both ends of the second capacitive element.

[0081] Therefore, when the mobile phone NFC transmits a field strength signal with a frequency of 13.56 MHz through the near field communication coil 104, when the mobile phone leather case is attached, the detection module 108 can detect the identification signal of the same frequency on the first identification element 106, thereby achieving accurate attachment detection.

[0082] By setting up a loop through the capacitive coupling effect of metal sheets, the fitting state of holsters and other containing accessories can be detected, achieving high-precision, highly anti-interference fitting detection at a low cost.

[0083] In some embodiments of the present application, Figure 3 and Figure 4 As shown, the first identification element 106 is a radio frequency antenna.

[0084] In the embodiment of the present application, the radio frequency antenna of the electronic device 100 is specifically a signal antenna of a mobile phone, and the radio frequency antenna can be an antenna set by the mobile phone itself, such as an LTE radio frequency antenna, a 5G radio frequency antenna, or a Wi-Fi radio frequency antenna. The antenna module 110 is connected to the radio frequency antenna, and the radio frequency signal is sent and received through the radio frequency antenna, thereby realizing the network function of the mobile phone.

[0085] Specifically, the mobile phone receives the identification signal emitted by the transmitting antenna 2068 provided on the leather case through the radio frequency antenna. After the radio frequency antenna receives the identification signal, it can be determined whether the leather case is attached to the mobile phone according to the signal strength of the identification signal.

[0086] The embodiment of the present application reuses the RF antenna of the mobile phone and sets a transmitting antenna 2068 on a holster or other storage accessory to transmit an identification signal to the RF antenna, thereby achieving accurate detection of the fitting status of the holster without adding additional identification devices to the mobile phone.

[0087] In some embodiments of the present application, the detection module 108 further includes:

[0088] The determination module 1084 is connected to the frequency selection acquisition module 1082 and is used to:

[0089] When the identification signal is detected and the voltage amplitude is greater than or equal to the voltage threshold, the bonding state is determined to be bonding:

[0090] When no identification signal is detected or the voltage amplitude is less than the voltage threshold, the bonding state is determined to be non-bonding.

[0091] In the embodiment of the present application, the electronic device 100 includes a determination module 1084, wherein the detection module 108 and the determination module 1084 may be independently arranged chip modules or algorithm modules in a processor.

[0092] After receiving the identification signal, the first identification element 106 sends the identification signal to the detection module 108. The detection module 108 can identify the voltage amplitude of the identification signal, and the determination module 1084 determines whether the leather case is attached to the electronic device 100 based on the comparison result of the voltage amplitude of the identification signal and the preset voltage threshold.

[0093] Specifically, if the voltage amplitude of the identification signal exceeds the voltage threshold, specifically is greater than or equal to the voltage threshold, it is determined that the receiving portion 202 of the accessory 200 of the electronic device such as a leather case is attached to the electronic device 100. If the voltage amplitude of the identification signal is lower than the voltage threshold, it is determined that the receiving portion 202 of the accessory 200 of the electronic device such as a leather case is not attached to the electronic device 100, or is not attached properly.

[0094] The present application detects the fitting state of accessories 200 of electronic devices such as leather cases by identifying the voltage amplitude of the signal. The detection has high accuracy and sensitivity and strong anti-interference ability, which can effectively reduce false detection and improve the reliability of fitting detection of leather cases and other decorative containers.

[0095] In some embodiments of the present application, the determination module 1084 is further configured to:

[0096] When the voltage amplitude is greater than or equal to the voltage threshold, the type of accessory 200 of the electronic device is determined based on the correspondence between the voltage amplitude and the preset voltage interval, wherein there are multiple preset voltage intervals and the preset voltage intervals and the types of accessories 200 of the electronic device are in a one-to-one correspondence.

[0097] In the embodiment of the present application, there may be multiple types of accessories 200 of electronic devices such as leather cases, and multiple electronic device accessories 200 may correspond to different preset rules. For example, the leather cases include brown leather cases and red leather cases. When the brown leather case is attached to the mobile phone, the mobile phone displays a brown theme interface, and when the red leather case is attached to the mobile phone, the mobile phone displays a red theme interface.

[0098] Different types of electronic device accessories 200 correspond to different preset voltage ranges. For example, when the detection module 108 of the mobile phone detects the identification signal, and the determination module 1084 determines that the voltage amplitude V1 of the identification signal is greater than the voltage threshold Vth, it is determined that a leather case is attached to the mobile phone.

[0099] At this time, the voltage interval corresponding to the voltage amplitude V1 is further determined. Assume that there is a preset voltage interval [Va, Vb) and a preset voltage interval [Vb, Vc], wherein the preset voltage interval [Va, Vb) is the interval corresponding to the brown leather case, and the preset voltage interval [Vb, Vc] is the interval corresponding to the red leather case.

[0100] If it is determined that Va<V1<Vb, it is determined that the currently fitted leather case is a brown leather case, and the system switches to the brown theme.

[0101] It can be understood that the coupling signal strength can be adjusted by changing the number of turns or the shape and size of the coupling coil inside the leather case, thereby changing the voltage amplitude of the identification signal.

[0102] By judging the type of the accessory 200 of the fitted electronic device based on the correspondence between the voltage amplitude of the identification signal and the preset voltage range, accurate identification of the receiving accessories of different styles and types is achieved, thereby improving the user experience of fitting detection.

[0103] In some embodiments of the present application, a control method is provided for controlling an electronic device as provided in any of the above embodiments. Figure 5 A flow chart of a control method according to an embodiment of the present application is shown. Figure 5 As shown, the method includes:

[0104] Step 502, detecting an identification signal;

[0105] Step 504: when the identification signal is detected and the voltage amplitude of the identification signal is greater than or equal to the voltage threshold, determining that the bonding state between the electronic device and the accessory is bonding;

[0106] Step 506: When no identification signal is detected or the voltage amplitude of the identification signal is less than the voltage threshold, it is determined that the fitting state between the electronic device and the accessory is not fitted.

[0107] In the embodiment of the present application, after the electronic device detects the identification signal on the first identification member, it identifies the voltage amplitude of the identification signal, and determines whether the leather case is attached to the electronic device based on the comparison result between the voltage amplitude of the identification signal and a preset voltage threshold.

[0108] Specifically, if the voltage amplitude of the identification signal exceeds the voltage threshold, specifically is greater than or equal to the voltage threshold, it is determined that the receiving portion of the leather case or other accessories is attached to the electronic device. If the voltage amplitude of the identification signal is lower than the voltage threshold, it is determined that the receiving portion of the leather case or other accessories is not attached to the electronic device, or is not attached properly.

[0109] The present application detects the fit status of accessories such as leather cases by identifying the voltage amplitude of the signal. The detection has high accuracy and sensitivity and strong anti-interference ability, which can effectively reduce false detection and improve the reliability of fit detection of leather cases and other decorative items.

[0110] In some embodiments of the present application, after detecting the identification signal, the control method further includes:

[0111] When the voltage amplitude is greater than or equal to the voltage threshold, the type of accessory is determined based on the correspondence between the voltage amplitude and the preset voltage interval, wherein there are multiple preset voltage intervals and the preset voltage intervals and the types of accessories are in a one-to-one correspondence.

[0112] In the embodiment of the present application, there may be multiple types of accessories such as leather cases, and multiple accessories may correspond to different preset rules. For example, the leather cases include brown leather cases and red leather cases. When the brown leather case is attached to the mobile phone, the mobile phone displays a brown theme interface, and when the red leather case is attached to the mobile phone, the mobile phone displays a red theme interface.

[0113] Different types of accessories correspond to different preset voltage ranges. For example, when the detection module of the mobile phone detects an identification signal, and the determination module determines that the voltage amplitude V1 of the identification signal is greater than the voltage threshold Vth, it is determined that a leather case is attached to the mobile phone.

[0114] At this time, the voltage interval corresponding to the voltage amplitude V1 is further determined. Assume that there is a preset voltage interval [Va, Vb) and a preset voltage interval [Vb, Vc], wherein the preset voltage interval [Va, Vb) is the interval corresponding to the brown leather case, and the preset voltage interval [Vb, Vc] is the interval corresponding to the red leather case.

[0115] If it is determined that Va<V1<Vb, it is determined that the currently fitted leather case is a brown leather case, and the system switches to the brown theme.

[0116] By judging the type of accessories of the fitted electronic device based on the correspondence between the voltage amplitude of the identification signal and the preset voltage range, accurate identification of accessories of different styles and types is achieved, thereby improving the user experience of fitting detection.
