Description

Technical Field

[0001] This application belongs to the field of electronic equipment technology, specifically relating to an electronic device, a control method, and a readable storage medium. Background Technology

[0002] Among related technologies, Near Field Communication (NFC) provides electronic devices with a secure and fast communication method.

[0003] The typical method for implementing NFC on mobile phones is to use the phone's metal frame as an NFC antenna. Specifically, the NFC module excites a current in the metal frame, generating a magnetic field. However, for foldable phones, when the phone is folded, the magnetic field generated by the NFC module through the metal frame on one side of the folded screen induces a current in the opposite direction in the metal frame on the other side. This induced current creates a magnetic field opposite in direction to the original magnetic field generated by the NFC module, causing the magnetic fields to cancel each other out and weaken the original magnetic field. Ultimately, this results in poor NFC performance in foldable phones. Summary of the Invention

[0004] This application aims to provide an electronic device, control method, and readable storage medium that can solve the problem of poor NFC performance in foldable screen phones in related technologies.

[0005] In a first aspect, embodiments of this application provide an electronic device, which includes:

[0006] The first folded body includes a first antenna radiator;

[0007] The second folding body is hinged to the first folding body, and the second folding body includes a second antenna radiator.

[0008] The near-field communication module includes a first feed path and a second feed path, wherein the first feed path is electrically connected to the first antenna radiator and the second feed path is electrically connected to the second antenna radiator.

[0009] In the case where the first folded body and the second folded body are folded together, the near-field communication module is used to generate current in the first antenna radiator through the first feeding path and to generate current in the second antenna radiator through the second feeding path. The direction of the current in the first antenna radiator is the same as the direction of the current in the second antenna radiator.

[0010] Secondly, embodiments of this application propose a control method applied to an electronic device, the electronic device including a first folding body, a second folding body, and a near-field communication module, the control method including:

[0011] Detect the folding state between the first folded body and the second folded body;

[0012] When a change in the folding state between the first folded body and the second folded body is detected, the near-field communication module is controlled to generate current in the first folded body and the second folded body.

[0013] The direction of the current generated by the near-field communication module in the first folded body is the same as the direction of the current generated by the near-field communication module in the second folded body.

[0014] Thirdly, embodiments of this application propose an electronic device including a processor and a memory, wherein the memory stores a program or instructions that can run on the processor, and when the program or instructions are executed by the processor, they implement the steps of the control method as described in the second aspect.

[0015] Fourthly, embodiments of this application propose a readable storage medium on which a program or instructions are stored, and when the program or instructions are executed by a processor, the steps of the control method as described in the second aspect are implemented.

[0016] In this embodiment, the near field communication module, i.e. the NFC module, excites current in the metal parts of the two folded bodies of the foldable screen electronic device, and ensures that the current direction of the excitation current in the metal parts of the two folded bodies after folding is the same. Therefore, when the electronic device is in the folded state, the magnetic field generated by the two metal frames is in the same direction. The magnetic fields in the same direction will be superimposed rather than canceled, thus improving the magnetic field strength, thereby improving the NFC signal strength and improving the NFC performance of the foldable screen phone.

[0032] The following is combined Figures 1 to 7 This application describes the electronic device, control method, and readable storage medium provided in the embodiments of this application.

[0033] In some embodiments of this application, an electronic device is provided. Figure 1 A schematic diagram of the structure of the electronic device provided in an embodiment of this application is shown, such as... Figure 1 As shown, the electronic device 10 includes:

[0034] The first folding body 11 includes a first antenna radiator 110;

[0035] The second folding body 12 is hinged to the first folding body 11, and the second folding body 12 includes a second antenna radiator 120.

[0036] The near-field communication module 13 includes a first feed path 132 and a second feed path 134. The first feed path 132 is electrically connected to the first antenna radiator 110, and the second feed path 134 is electrically connected to the second antenna radiator 120.

[0037] When the first folding body 11 and the second folding body 12 are folded together, the near-field communication module 13 is used to generate current in the first antenna radiator 110 through the first feeding path 132 and to generate current in the second antenna radiator 120 through the second feeding path 134. The current direction in the first antenna radiator 110 is the same as the current direction in the second antenna radiator 120.

[0038] In this embodiment of the application, the electronic device 10 is specifically a foldable electronic device 10, such as a foldable screen mobile phone. The electronic device 10 includes a first folding body 11 and a second folding body 12, wherein the first folding body 11 and the second folding body 12 are hinged together by a hinge 16.

[0039] The first folding body 11 includes a first antenna radiator 110, and the second folding body 12 includes a second antenna radiator 120. Taking the electronic device 10 as a foldable screen mobile phone as an example, the first folding body 11 corresponds to one side of the folding screen of the folding screen mobile phone, such as the left folding screen or the upper folding screen. At this time, the first antenna radiator 110 is specifically the metal frame of the left folding screen or the upper folding screen.

[0040] The second folding body 12 corresponds to the other side of the folding screen of the folding screen phone, such as the right folding screen or the bottom folding screen. In this case, the second antenna radiator 120 is specifically the metal frame of the right folding screen or the bottom folding screen.

[0041] The near-field communication module 13 is specifically an NFC module. The NFC module 13 includes a first feeding path 132 and a second feeding path 134. The first feeding path 132 is connected to the first antenna radiator 110, and the second feeding path 134 is connected to the second antenna radiator 120. When the NFC module is working, the first feeding path 132 can excite the first antenna radiator 110, i.e., the metal frame on one side of the foldable screen, to generate current in the first antenna radiator 110. The second feeding path 134 can excite the second antenna radiator 120, i.e., the metal frame on the other side of the foldable screen, to generate current in the second antenna radiator 120.

[0042] Specifically, when the first folding body 11 and the second folding body 12 are folded together, that is, when the foldable screen phone is in a folded state, the direction of the current induced by the first feeding path 132 in the first antenna radiator 110 is the same as the direction of the current induced by the second feeding path 134 in the second antenna radiator 120 to form the layer current. Therefore, the magnetic field directions formed in the two metal frames of the folded screen are also the same. Figure 1 As shown, magnetic fields with the same direction will superimpose each other, strengthening the original magnetic field and thus enhancing NFC performance.

[0043] This application embodiment excites currents in the same direction in the metal frames of the two folding bodies of a foldable phone, thereby generating magnetic fields in the same direction in the two metal frames. The magnetic fields are superimposed and enhanced, thereby increasing the NFC performance of the foldable phone.

[0044] In some embodiments of this application, the magnitude of the current formed by the first feed path 132 in the first antenna radiator 110 is the same as the magnitude of the current formed by the second feed path 134 in the second antenna radiator 120.

[0045] In this embodiment of the application, when the near-field communication module 13 is working, the first feed path 132 forms a current in the first antenna radiator 110, and the second feed path 134 forms a current in the second antenna radiator 120. The magnitude of the current formed by the first feed path in the first antenna radiator 110 is the same as the magnitude of the current formed by the second feed path 134 in the second antenna radiator 120.

[0046] Therefore, the magnitude and direction of the current in the first metal frame and the second metal frame are equal, so the magnetic field generated by the second metal frame has the same direction and characteristics as the magnetic field generated by the first metal frame. These two magnetic fields can be superimposed to improve NFC performance.

[0047] In some embodiments of this application, the first antenna radiator 110 includes a first feed point 1102 and a ground point 1104. The first feed point 1102 is electrically connected to the first feed path 132, and the ground point 1104 is grounded.

[0048] The second antenna radiator 120 includes a second feed point 1202 and a third feed point 1204. One of the second feed point 1202 and the third feed point 1204 is electrically connected to the second feed path 134, and the other of the second feed point 1202 and the third feed point 1204 is grounded.

[0049] In the embodiments of this application, such as Figure 1 As shown, the first antenna radiator 110 includes a first feed point 1102 and a ground point 1104. The first feed path 132 is electrically connected to the first feed point 1102 and excites a current between the first feed point 1102 and the ground point 1104. The direction of the current is from the first feed point 1102 to the ground point 1104.

[0050] The second antenna radiator 120 includes a second feed point 1202 and a third feed point 1204. One of the second feed point 1202 and the third feed point 1204 is electrically connected to the second feed path 134, and the other of the second feed point 1202 and the third feed point 1204 is grounded.

[0051] like Figure 1 As shown, when the first folded body 11 and the second folded body 12 are in the folded state, the second feed path 134 is connected to the second feed point 1202. At this time, the third feed point 1204 is grounded, and the current direction is from the second feed point 1202 to the third feed point 1204, which is consistent with the current direction in the first antenna radiator 110.

[0052] Figure 2 A schematic diagram of the structure of the electronic device 10 provided in an embodiment of this application is shown, as follows: Figure 2As shown, when the first folded body 11 and the second folded body 12 are in the unfolded state, the second feed path 134 is connected to the third feed point 1204. At this time, the second feed point 1202 is grounded, and the current direction is from the third feed point 1204 to the second feed point 1202, which is consistent with the current direction in the first antenna radiator 110.

[0053] This application embodiment achieves NFC functionality through a metal frame by setting a power supply point and a grounding point 1104 on the metal frame for connecting the power supply path, without the need to add an NFC coil, making the implementation of NFC functionality simpler and more reliable.

[0054] In some embodiments of this application, Figure 3 A circuit diagram of the switching circuit 14 provided in an embodiment of this application is shown, as follows: Figure 3 As shown, the electronic device 10 further includes: a switching circuit 14, the first end of the switching circuit 14 being electrically connected to the second power supply path 134, the second end of the switching circuit 14 being electrically connected to the second power supply point 1202, the third end of the switching circuit 14 being electrically connected to the third power supply point 1204, and the fourth end of the switching circuit 14 being grounded.

[0055] In the embodiments of this application, such as Figure 1 As shown, when the first folded body 11 and the second folded body 12 are in the folded state, the current direction in the first antenna radiator 110 is the same as the current direction in the second antenna radiator 120. Figure 3 A schematic diagram of the structure of the electronic device 10 provided in an embodiment of this application is shown, as follows: Figure 3 As shown, if the current direction in the two metal parts remains unchanged, then after deployment, the current direction in the first antenna radiator 110 is opposite to the current direction in the second antenna radiator 120.

[0056] If the current directions in the first antenna radiator 110 and the second antenna radiator 120 are opposite, and the distance between the first antenna radiator 110 and the second antenna radiator 120 is not far enough, the magnetic field generated by the first antenna radiator 110 and the magnetic field generated by the second antenna radiator 120 will cancel each other out in the NFC card surface, thus creating a card reading blind zone.

[0057] In this case, the present application also provides a switching circuit 14, such as Figure 3As shown, the switching circuit 14 can be a double-pole double-throw (DPDT) switching circuit. By setting the switching circuit 14, the connection relationship between the second feed point 1202, the third feed point 1204 and the second feed path 134 and the ground can be switched, thereby adjusting the current direction in the second antenna radiator 120 so that when the first folded body 11 and the second folded body 12 are in the unfolded state, the current direction between the first antenna radiator 110 and the second antenna radiator 120 can also remain the same.

[0058] This application embodiment sets up a switching circuit 14 so that the current direction induced by the NFC module in the two metal frames of the foldable screen phone is always the same, avoiding card reading blind spots when the foldable screen phone is in the unfolded state and improving the convenience of NFC use.

[0059] In some embodiments of this application, such as Figure 3 As shown, the electronic device 10 further includes: a control circuit 15 electrically connected to the switching circuit 14. The control circuit 15 is used to connect the first end of the switching circuit 14 to the second end of the switching circuit 14 and connect the third end of the switching circuit 14 to the fourth end of the switching circuit 14 when the first folding body 11 and the second folding body 12 are folded; and to connect the first end of the switching circuit 14 to the third end of the switching circuit 14 and connect the second end of the switching circuit 14 to the fourth end of the switching circuit 14 when the first folding body 11 and the second folding body 12 are unfolded, so that the current direction in the first antenna radiator 110 is the same as the current direction in the second antenna radiator 120.

[0060] In the embodiments of this application, such as Figure 1 As shown, when the first folding body 11 and the second folding body 12 are in the folded state, the control circuit 15 controls the switching circuit 14 so that the first end of the switching circuit 14 is connected to the second end of the switching circuit 14 and the third end of the switching circuit 14 is connected to the fourth end of the switching circuit 14. At this time, the second power supply path 134 is connected to the second power supply point 1202 and the third power supply point 1204 is grounded. At this time, the current direction in the first folding body 11 is the same as the current direction in the second folding body 12.

[0061] When the first folded body 11 and the second folded body 12 are in the unfolded state Figure 4 A schematic diagram of the structure of the electronic device 10 provided in an embodiment of this application is shown, as follows: Figure 4As shown, if the second feed path 134 is connected to the second feed point 1202 and the third feed point 1204 is grounded, the current direction in the first antenna radiator 110 is opposite to the current direction in the second antenna radiator 120. If the distance between the first antenna radiator 110 and the second antenna radiator 120 is not far enough, the magnetic field generated by the first antenna radiator 110 and the magnetic field generated by the second antenna radiator 120 will cancel each other out in the NFC card surface, thus creating a card reading blind zone.

[0062] When the first folding body 11 and the second folding body 12 are in the unfolded state, the control circuit 15 controls the switching circuit 14 to switch the connection mode of the second feed point 1202, the third feed point 1204, the second feed path 134, and the grounding point 1104, so that the second feed path 134 is connected to the third feed point 1204, and the second feed point 1202 is grounded. Figure 2 As shown, at this time, the current direction in the first folded body 11 is the same as the current direction in the second folded body 12.

[0063] This application embodiment sets up a control circuit 15 to control the switching circuit 14 to adjust the connection method of the feed point on the second antenna radiator 120 according to the folding state of the first folding body 11 and the second folding body 12, thereby adjusting the current direction in the second antenna radiator 120, so that the current direction in the metal frame of the two folding screens of the folding phone is always the same no matter what state the folding phone is in, which can improve the NFC performance of the folding screen phone.

[0064] In some embodiments of this application, when the first folding body 11 and the second folding body 12 are folded together, the position of the first power supply point 1102 is opposite to the position of the third power supply point 1204, and the position of the grounding point 1104 is opposite to the position of the second power supply point 1202.

[0065] In the embodiments of this application, such as Figure 1 As shown, when the first folding body 11 and the second folding body 12 are in a folded state, the position of the first power supply point 1102 is opposite to the position of the third power supply point 1204, and the position of the grounding point 1104 is opposite to the position of the second power supply point 1202.

[0066] Specifically, the metal frame portion between the first feed point 1102 and the ground point 1104 forms the NFC antenna on the first folding body 11, and the metal frame portion between the second feed point 1202 and the third feed point 1204 forms the NFC antenna on the second folding body 12. By setting the positions of the first feed point 1102 and the third feed point 1204 to be opposite each other, and setting the position of the ground point 1104 to be opposite to the position of the second feed point 1202, the NFC antennas of the two folding parts of the folding screen phone can be positioned opposite each other. At this time, the current directions in the first antenna radiator 110 and the second antenna radiator 120 are also the same, so that the magnetic field direction and position generated by the two NFC antennas are the same.

[0067] At this point, the magnetic fields generated on the two metal frames superimpose, which can enhance the magnetic field and thus improve the NFC signal strength.

[0068] In this embodiment, the positions of the first feed point 1102 and the third feed point 1204 are set to be opposite each other, and the positions of the ground point 1104 and the second feed point 1202 are set to be opposite each other, so that the NFC antennas on the two parts of the folding body are opposite to each other, thereby making the magnetic fields generated by the two NFC antennas superimposed and improving the NFC performance of the folding screen phone.

[0069] In some embodiments of this application, when the first folding body 11 and the second folding body 12 are folded together, the positions of the first antenna radiator 110 and the second antenna radiator 120 are opposite each other.

[0070] In this embodiment, the metal portion between the first feed point 1102 and the ground point 1104 is the first antenna radiator 110. The metal portion between the second feed point 1202 and the third feed point 1204 is the second antenna radiator 120.

[0071] like Figure 1 As shown, by setting the antenna radiators on the two folded parts of the foldable phone to be opposite each other and setting the current direction within the two antenna radiators to be the same, the magnetic field direction and position generated by the two antenna radiators can be kept the same.

[0072] At this point, the magnetic fields generated on the two antenna radiators superimpose, which can enhance the magnetic field and thus improve the NFC signal strength.

[0073] This application embodiment improves the NFC performance of foldable screen phones by setting the positions of the radiating branches on the two folding bodies to be opposite each other, so that the magnetic fields generated on the two radiating branches can be superimposed.

[0074] In some embodiments of this application, the near-field communication module 13 is used to establish a near-field communication connection with a near-field communication device, the near-field communication device including a near-field communication coil;

[0075] When the first folded body 11 and the second folded body 12 are unfolded, the distance between the first feed point 1102 and the third feed point 1204 is less than the diameter of the near-field communication coil.

[0076] In the embodiments of this application, such as Figure 4 As shown, near-field communication devices are... Figure 4 The NFC card shown has an NFC coil. The near-field communication module 13 can excite an induced current in the NFC coil to achieve near-field communication.

[0077] The portion between the first feed point 1102 and the third feed point 1204 is the NFC blind zone of the electronic device 10. By controlling the distance between the first feed point 1102 and the third feed point 1204 to be less than the diameter of the near-field communication coil, it is possible to prevent external NFC devices from being completely within the NFC blind zone, thus avoiding NFC communication failure and ensuring the reliability of NFC communication.

[0078] In some embodiments of this application, a control method is provided for an electronic device, the electronic device including a first folded body, a second folded body, and a near-field communication module.

[0079] Figure 5 A flowchart of the control method provided in an embodiment of this application is shown, such as... Figure 5 As shown, the control methods include:

[0080] Step 502: Detect the folding state between the first folding body and the second folding body;

[0081] Step 504: When a change in the folding state between the first folding body and the second folding body is detected, the near-field communication module is controlled to generate current in the first folding body and the second folding body.

[0082] The direction of the current generated by the near-field communication module in the first folded body is the same as the direction of the current generated by the near-field communication module in the second folded body.

[0083] In this embodiment of the application, after detecting a change in the folding state between the first folded body and the second folded body, the electronic device controls the near-field communication module to excite currents on the first antenna radiator of the first folded body and the second antenna radiator of the second folded body through the first feeding path and the second feeding path, respectively, and makes the current direction on the first antenna radiator the same as the current direction on the second antenna radiator.

[0084] Taking a foldable screen phone as an example, the first folding body and the second folding body are the two folded parts of the foldable screen, and the first antenna radiator and the second antenna radiator are the metal frames on both sides of the foldable screen.

[0085] By exciting currents in the same direction in the first antenna radiator and the second technical section, the magnetic fields formed by the metal frames on both sides can be made to be in the same direction. The magnetic fields with the same direction can be superimposed to enhance the magnetic field strength, thereby enhancing the original magnetic field and thus enhancing the NFC performance.

[0086] This application embodiment excites currents in the same direction in the metal frames of the two folding bodies of a foldable phone, thereby generating magnetic fields in the same direction in the two metal frames. The magnetic fields are superimposed and enhanced, thereby increasing the NFC performance of the foldable phone.

[0087] In some embodiments of this application, the electronic device further includes a switching circuit, the near-field communication module includes a first power supply path and a second power supply path, the first folding body includes a first power supply point and a grounding point, the first power supply point is connected to the first power supply path, and the grounding point is grounded; the second folding body includes a second power supply point and a third power supply point, the switching circuit is electrically connected to the second power supply path, and the second power supply point and the third power supply point are electrically connected.

[0088] The steps of controlling the near-field communication module to generate current in the first folded body and the second folded body include:

[0089] When the first folding body and the second folding body are folded together, the control switching circuit connects the second feed point to the second feed path and grounds the third feed point.

[0090] When the first folding body and the second folding body are unfolded, the control switching circuit grounds the second feed point and connects the third feed point to the second feed path.

[0091] In this embodiment of the application, the first antenna radiator includes a first feed point and a ground point. The first feed path is electrically connected to the first feed point and excites a current between the first feed point and the ground point. The direction of the current is from the first feed point to the ground point.

[0092] The second antenna radiator includes a second feed point and a third feed point, one of which is electrically connected to the second feed path, and the other of which is grounded.

[0093] When the electronic device has NFC enabled, the folding state of the first folding body and the second folding body is detected in real time. If the first folding body and the second folding body are detected to be folded, the first power supply path is electrically connected to the first power supply point, and a current is induced between the first power supply point and the ground point. The direction of the current is from the first power supply point to the ground point.

[0094] The switching circuit connects the second feed path to the second feed point. At this time, the third feed point is grounded, and the current direction is from the second feed point to the third feed point, which is the same as the current direction in the first antenna radiator.

[0095] If the first folded body and the second folded body are detected to unfold, the first power supply path is electrically connected to the first power supply point, and a current is excited between the first power supply point and the grounding point. The direction of the current is from the first power supply point to the grounding point.

[0096] The switching circuit connects the second feed path to the third feed point, and the second feed point is grounded. At this time, the current direction is from the third feed point to the second feed point, which is still consistent with the current direction in the first antenna radiator.
