[0002] With the development of communication technology, electronic devices can exchange data through near field communication (NFC) technology when they are close to each other. At present, the NFC technology is widely used in mobile payment, electronic ticketing, access control and mobile identity recognition and other business scenarios.

[0003] In the related art, when a user uses the NFC function of an electronic device to perform mobile payment or card swiping and the like, the user usually needs to place the sensing area of the electronic device close to the sensing area of an external device. Since the sensing area of the device is small, a deviation in position between the sensing areas is prone to occur. For example, when a card is swiped using the NFC function, if the user does not align the sensing area of the electronic device with the sensing area of a pos machine, the card cannot be sensed through NFC. As a result, the success rate of NFC is low. SUMMARY

[0019] The technical solutions in the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art belong to the scope of protection of the present application.

[0020] The terms "first", "second", and the like in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally a category and do not limit the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / ", generally indicates that the front and rear associated objects are in a "or" relationship.

[0021] The near field communication (NFC) antenna position adjustment method provided by the embodiments of the present application will be described in detail below with reference to the drawings and specific embodiments and application scenarios.

[0022] Near field communication (NFC) is a new technology. Devices (such as mobile phones) using NFC technology can exchange data when they are close to each other. It is evolved from non-contact radio frequency identification (RFID) and interconnection technology. By integrating inductive card readers, inductive cards and point-to-point communication functions on a single chip, mobile terminals can be used for mobile payment, electronic ticketing, access control, mobile identity recognition, anti-counterfeiting and other applications. With the development of technology, users use NFC in more and more scenarios.

[0023] Currently, due to different hardware stacks of different models, the best NFC sensing area of different models is different. When users use different models, the problem of position deviation of the sensing area or the problem of long distance between the sensing area and the external device often occur, resulting in low success rate of using NFC.

[0024] In the NFC antenna position adjustment method provided by the embodiments of the present application, when a user uses the NFC function of an electronic device for card swiping and other operations, the NFC antenna position adjustment device can adaptively adjust the position of the NFC antenna, and adjust the position of the NFC antenna to the position with the maximum field strength, that is, the position with the best communication effect, thereby improving the success rate of NFC.

[0025] Figure 1A flowchart of a near field communication (NFC) antenna position adjustment method provided in an embodiment of the present application is shown in FIG. 8. The NFC antenna position adjustment method can include the following steps 201 and 202. Figure 1

[0026] Step 201: Obtain field intensity information of a communication environment in which the electronic device is located.

[0027] In an embodiment of the present application, the communication environment is a wireless communication environment in which the electronic device performs near field communication.

[0028] In an embodiment of the present application, the field intensity information can be a field intensity value.

[0029] In an embodiment of the present application, the field intensity information can include at least one of magnetic field intensity information and electric field intensity information.

[0030] In an embodiment of the present application, the field intensity information can include field intensity information at different positions.

[0031] In an embodiment of the present application, the electronic device can obtain external field intensity data by sensing electromagnetic waves emitted by an external device through an NFC antenna, and then obtain the field intensity information based on the external field intensity data.

[0032] In an embodiment of the present application, the NFC antenna is a near field coupling antenna, and the coupling mode is coil magnetic field coupling.

[0033] It should be noted that the NFC antenna is used for near field communication (NFC), and "near field communication" refers to communication through near electromagnetic field radio waves. NFC occurs between an initiating device and a target device, and any NFC device can be an initiating device or a target device. The two devices are coupled to each other in an alternating magnetic field mode, and are carrier-modulated in an ASK mode or an FSK mode to achieve transmission of digital signals and exchange of data.

[0034] Step 202: Control the NFC antenna of the electronic device to move to a target position according to the field intensity information.

[0035] The target position corresponds to a maximum field intensity.

[0036] In an embodiment of the present application, the near field communication (NFC) antenna position adjustment apparatus can obtain field intensity information at different positions, determine a target position with maximum field intensity, and control the NFC antenna of the electronic device to move to the target position.

[0037] ​It can be understood that when NFC communication is performed, the field strength at different positions in the wireless communication environment of the NFC communication can be different, and the position with the maximum field strength is the optimal communication position, so the NFC antenna of the electronic device can be controlled to move to the position to improve the communication effect of the near field communication.

[0038] In the method for adjusting the position of the NFC antenna provided in the embodiments of the present application, the field strength information of the communication environment where the electronic device is located is acquired, and then the NFC antenna of the electronic device is controlled to move to a target position according to the field strength information; wherein the field strength information acquired at the target position is the maximum. Through the method, the position with the maximum field strength in the communication environment of the electronic device can be determined, that is, the position with the optimal communication effect, and the NFC antenna of the electronic device is controlled to move to the position, so that the position of the NFC antenna is adaptively adjusted, thereby improving the success rate of the electronic device when performing the NFC function.

[0039] Optionally, in the embodiments of the present application, the field strength information includes first field strength information and second field strength information; and the step 201 can include the following step 201a1 and step 201a2.

[0040] The step 201a1: controlling the NFC antenna of the electronic device to move in a first direction, and acquiring the first field strength information in the process of moving the NFC antenna.

[0041] The step 201a2: controlling the NFC antenna of the electronic device to move in a second direction, and acquiring the second field strength information in the process of moving the NFC antenna.

[0042] In some embodiments, the first direction and the second direction can be any direction parallel or approximately parallel to the plane where the display screen of the electronic device is located, and the first direction and the second direction are perpendicular.

[0043] In some embodiments, the first direction can be a direction parallel to the vertical edge of the electronic device, and the second direction can be a direction parallel to the horizontal edge of the electronic device.

[0044] For example, the first direction can be referred to as the Y-axis direction, and the second direction can be referred to as the X-axis direction.

[0045] In some embodiments, the first direction and the second direction can be diagonal directions of the electronic device, and the first direction and the second direction intersect.

[0046] Exemplarily, the first field intensity information and the second field intensity information each include a plurality of field intensity information. Further, the plurality of field intensity information is field intensity information at different positions.

[0047] Exemplarily, the NFC antenna position adjusting apparatus acquires the field intensity data of the electromagnetic wave emitted by the external device in real time or periodically during the movement of the NFC antenna in the first direction.

[0048] It can be understood that the movement of the NFC antenna in the first direction enables the NFC antenna to receive radio waves at different positions in the first direction, thereby obtaining the field intensity information at the different positions.

[0049] It should be noted that during the movement of the NFC antenna, the inductive distance between the NFC antenna and the NFC antenna of the external device or the NFC card is different when the NFC antenna is at different positions, and in the case of different inductive distances, the field intensity of the radio wave emitted by the external device received by the electronic device is different. The external device can be an access control device or a POS machine, and the NFC card can be a transportation card, a medical card, etc.

[0050] For example, taking the first direction as a direction parallel to the vertical edge of the electronic device and the second direction as a direction parallel to the horizontal edge of the electronic device, the NFC antenna position adjusting apparatus can control the NFC antenna to move in a direction parallel to the vertical edge of the electronic device, acquire the field intensity information at each position of the NFC antenna during the movement, and then control the NFC antenna to move in a direction parallel to the horizontal edge of the electronic device, and acquire the field intensity information at each position of the NFC antenna during the movement.

[0051] It should be noted that in the embodiments of the present application, the position of the NFC antenna refers to the position of the center point of the NFC antenna.

[0052] Exemplarily, the NFC antenna can be mounted on a guide rail, which can be fixed inside the electronic device, and the NFC antenna position adjusting apparatus can control the NFC antenna to move on the guide rail to move the antenna to any position in the electronic device where the guide rail is located.

[0053] Optionally, in the embodiments of the present application, the step 202 can include the following steps 202a1 and 202a2:

[0054] Step 202a1: determining a target position according to the first field intensity information and the second field intensity information.

[0055] Step 202a2: controlling the NFC antenna of the electronic device to move to the target position.

[0056] In some examples, the NFC antenna position adjustment apparatus can determine a first position with the maximum field strength information in the first direction according to the first field strength information, and determine a second position with the maximum field strength information in the second direction according to the second field strength information, and then determine the target position according to the first position and the second position. Exemplarily, the target position is the position with the minimum distance to both the first position and the second position.

[0057] In some examples, the NFC antenna position adjustment apparatus can determine a first position with the maximum field strength information in the first direction according to the first field strength information, and control the NFC antenna to move to the first position, and then control the NFC antenna to move in the second direction from the first position, and determine a position with the maximum field strength information in the second direction, i.e. the target position, and then control the NFC antenna to move to the target position.

[0058] Exemplarily, when the NFC antenna position adjustment apparatus detects that the user uses the NFC, it controls the NFC antenna to move in the Y-axis direction, and determines a first position of the NFC antenna in the Y-axis direction when the field strength information is the maximum during the movement in the Y-axis direction, and then controls the NFC antenna to move to the first position, and then controls the NFC antenna to move in the X-axis direction from the first position, and determines a position of the NFC antenna in the X-axis direction when the field strength information is the maximum during the movement in the X-axis direction, i.e. the target position, which is the optimal position for the NFC with the external device.

[0059] Optionally, before the step 202, the NFC antenna position adjustment method provided in the embodiments of the present application further includes the following steps A1 and A2:

[0060] Step A1: determining a target sensing area on the electronic device according to a holding area of the target user on the electronic device.

[0061] The target sensing area is at least part of the area on the electronic device other than the holding area.

[0062] Exemplarily, the target sensing area is at least part of the area on the back of the electronic device other than the holding area, i.e. at least part of the area on the back of the electronic device that is not blocked.

[0063] Step A2: controlling the NFC antenna of the electronic device to move to the target sensing area.

[0064] Optionally, when the NFC antenna position adjustment apparatus detects that the user turns on the NFC function, it detects the holding area of the user on the electronic device, and determines the target sensing area according to the holding area.

[0065] Exemplarily, the target sensing area can be a circular area or a rectangular area or any other shape, and the embodiments of the present application do not limit the shape of the target sensing area.

[0066] Exemplarily, the NFC antenna position adjustment apparatus can count the user's multiple grips on the electronic device, and then determine the target sensing area by using the grip area with a higher frequency among the multiple grip areas and by determining at least part of the area outside the grip area as the target sensing area, thereby obtaining the target sensing area that conforms to the user's usage habit.

[0067] In some embodiments of the present application, the NFC antenna position adjustment apparatus detects the user's touch position on the screen and the area of the contact surface with the screen through the touch sensor of the electronic device, and then determines the user's grip area on the electronic device based on the touch position and the area of the contact surface through a deep learning algorithm.

[0068] Exemplarily, in the case where the touch sensor detects that the user's multiple fingers are respectively located at the edge area of the lower half of the screen, it is determined that the user's palm is in contact with the lower half area of the back of the electronic device, and the target sensing area can be determined as the upper half area of the back of the electronic device.

[0069] Exemplarily, in the case where the touch sensor detects that the area of the contact surface between the user's palm and the screen is large and the contact surface is located in the lower part of the screen of the electronic device, it is determined that the user's fingers are in contact with the lower-middle part of the back of the electronic device, and the target sensing area can be determined as the upper half area of the back of the electronic device.

[0070] Exemplarily, in the case where the touch sensor detects that the user's multiple fingers are respectively located at the edge area of the upper half of the screen, it is determined that the user's palm is in contact with the upper half area of the back of the electronic device, and the target sensing area can be determined as the lower half area of the back of the electronic device.

[0071] It should be noted that the target sensing area is an area that is not in contact with the user's fingers or palm, that is, the target sensing area is an area that the user is used to for NFC sensing with an external device (such as an access control device), and therefore, the NFC antenna can be moved to this area to make the sensing distance between the NFC antenna and the antenna of the external device closer, so as to improve the success rate of NFC.

[0072] In this way, the NFC antenna position adjustment apparatus can move the NFC antenna to an area that the user is used to for NFC sensing according to the user's grip habit on the electronic device, thereby improving the success rate of NFC.

[0073] Further optionally, in the embodiments of the present application, the NFC antenna is an NFC antenna coil; and the step A2 can include the following steps B1 and B2:

[0074] Step B1: The NFC antenna position adjustment device determines the center point of the NFC antenna coil.

[0075] Step B2: The NFC antenna position adjustment device controls the movement of the NFC antenna coil until the center point of the NFC antenna coil coincides with the center point of the target induction area.

[0076] For example, in the case of determining the target induction area, the NFC antenna position adjustment device obtains the center point of the target induction area, and then controls the movement of the NFC antenna through the guide rail so that the center point of the NFC antenna is located at the position of the center point of the target induction area.

[0077] In some embodiments of the present application, when the NFC is detected to be turned on, the NFC antenna position adjustment device detects the manner and position of the user holding the electronic device, determines the approximate position where the user needs to be inducted when using the NFC, and moves the NFC antenna to the position preliminarily. When the user uses the NFC is detected (for example, the signal sent by the external device is detected), the NFC antenna is controlled to move from the position in the Y-axis direction, the first position where the field intensity is the strongest in the Y-axis direction is determined through the change of the NFC field intensity during the movement, and the NFC antenna is moved to the first position. Then, the NFC antenna is controlled to move from the first position in the X-axis direction, the target position where the field intensity is the strongest in the X-axis direction is determined, and the NFC antenna is moved to the target position, so as to fix the NFC antenna to the best position for performing the NFC.

[0078] It should be noted that, generally, the area of the NFC antenna coil of the electronic device is fixed and much smaller than the area of the induction area required by the user, and therefore, after the NFC antenna is moved to the target induction area, the movement in the X-axis direction and the Y-axis direction can be performed to further determine the best position of the NFC antenna.

[0079] Optionally, in the embodiments of the present application, the electronic device further includes a first guide rail parallel to the first direction, and a second guide rail parallel to the second direction, the NFC antenna is installed on the second guide rail, and the second guide rail is installed on the first guide rail.

[0080] Optionally, the control of the movement of the NFC antenna of the electronic device in the first direction in the step 201a1 can be implemented by the following step 201b1, and the control of the movement of the NFC antenna of the electronic device in the second direction in the step 201a2 can be implemented by the following step 202b2:

[0081] Step 201b1: controlling the NFC antenna to move in the first direction through the first guide rail.

[0082] Step 202b2: controlling the NFC antenna of the electronic device to move in the second direction through the second guide rail.

[0083] Exemplarily, the NFC antenna can be fixed on a first sliding member, which is installed on the upper surface of the second guide rail and can move on the second guide rail under driving to make the NFC antenna move in the first direction.

[0084] Exemplarily, the lower surface of the second guide rail is installed with a second sliding member, which is slidingly installed on the first guide rail and can move on the first guide rail under driving to make the NFC antenna move in the second direction.

[0085] Exemplarily, FIG. 2(a) is a schematic diagram of the NFC antenna and the guide rails provided by the embodiment of the present application. As shown in FIG. 2(a), the NFC antenna 20 is provided in the electronic device, the center of the bottom surface of the NFC antenna is installed with a first sliding member, the first sliding member is provided at the midpoint of the horizontal guide rail 21 (i.e., the X-axis direction guide rail), the guide rail 21 and the vertical guide rail 22 are connected through a second sliding member, and the second sliding member is provided on the lower surface of the guide rail 21.

[0086] In some embodiments of the present application, in combination with the above-mentioned FIG. 2(a), the NFC antenna position adjustment device determines that the position with the maximum field intensity information in the first direction is the first position when detecting that the user uses the NFC, assuming that the first position is point A in the Y-axis direction, the NFC antenna position adjustment device moves the center point of the NFC antenna 20 to the above-mentioned point A through the guide rail 22, as shown in FIG. 2(b); assuming that the target position is point B in the X-axis direction, the NFC antenna position adjustment moves the center point of the NFC antenna 20 from the point A to the point B through the guide rail 21, as shown in FIG. 2(c). In this way, the NFC antenna can reach any area position of the electronic device through the guide rails in the X-axis and Y-axis directions.

[0087] In the NFC antenna position adjustment method provided by the embodiment of the present application, the NFC antenna position adjustment device can automatically adjust the optimal NFC antenna sensing area according to the user's behavior habit of holding the electronic device, without the need for the user to actively learn and understand, thereby effectively improving the success rate of the user using the NFC, avoiding multiple attempts caused by position deviation, and improving the operation efficiency.

[0088] The NFC antenna position adjustment method provided by the embodiment of the present application can be executed by an NFC antenna position adjustment device. The NFC antenna position adjustment method executed by the NFC antenna position adjustment device is taken as an example to illustrate the NFC antenna position adjustment device provided by the embodiment of the present application.
