[0020] In order for those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should be within the scope of protection of the present application.

[0021] Figure 1 A flowchart schematic diagram of the relative direction determination method provided by the embodiments of the present application is shown, which can be applied to an electronic device provided with a millimeter wave antenna, such as shown in Figure 1 The method can include the following steps.

[0022] S102: Rotating the millimeter wave antenna, which is used to emit millimeter wave signals and receive the reflected millimeter wave signals.

[0023] In an embodiment, the millimeter wave antenna in the electronic device is periodically rotated (or rotated) after being started, emits millimeter wave signals and receives the reflected millimeter wave signals reflected by the obstacles, and a monitoring module in the electronic device analyzes the received millimeter wave signals to determine whether a target object is detected.

[0024] S104: Determining that the millimeter wave antenna detects a target object based on the millimeter wave signals, and determining the rotation angle of the millimeter wave antenna.

[0025] In an embodiment, it is determined that a target object is detected based on the signal strength of the millimeter wave signals that can be received by the obstacles. Of course, this embodiment can also be combined with other technical means, such as the time length during which the millimeter wave signals reflected by the obstacles can be received exceeds a first time length; at the same time, the distance between the electronic device and the obstacle is detected to be lower than a first threshold, it is determined that a target object is detected.

[0026] This embodiment can determine the rotation angle of the millimeter wave antenna after determining that a target object is detected, which is beneficial to reduce the resource overhead of continuously determining the rotation angle; of course, this embodiment can also determine the rotation angle of the millimeter wave antenna at the same time when the millimeter wave antenna is rotated, and then the rotation angle of the millimeter wave antenna at the time when the target object is detected can be determined.

[0027] S106: Determine the relative direction between the target object and the electronic device based on the rotation angle of the millimeter-wave antenna.

[0028] like Figure 2 and Figure 3 As shown, in one embodiment, assuming the millimeter-wave antenna 1 is installed inside an electronic device (such as a mobile phone) with a regular rectangular shape, the millimeter-wave antenna 1 can... Figure 2 The device rotates 360° within a two-dimensional plane, and the direction of its millimeter-wave signal transmission is parallel to the two-dimensional plane.

[0029] In one example, when the rotation angle of millimeter-wave antenna 1 is 0°, the line of sight of millimeter-wave antenna 1 and Figure 3 The arrows on the electrical connector 6 (specifically, a metal contact spring) are parallel to each other. This 0° direction can be visually marked on the base 5. When the rotatable millimeter-wave antenna 1 is applied to an electronic device, the direction of the visually marked arrows and... Figure 2 The direction A shown is parallel, meaning the above calibration is performed using the structural identification method.

[0030] Based on the rotation angle of millimeter-wave antenna 1, in Figure 2 In the example shown, the relative directions corresponding to the rotation angles of the millimeter-wave antenna 1 can be set as follows: at 0°, the transmission direction of the millimeter-wave antenna 1 is side A; at 90°, it is side B; at 180°, it is side C; at 270°, it is side D; and at 360°, it is side A. Thus, in a two-dimensional plane parallel to the side of the electronic device on which it is mounted, the transmission direction of the millimeter-wave antenna 1 has the ability to identify relative directions, that is, to determine which side of the electronic device the millimeter-wave signal is being transmitted towards.

[0031] Since the transmission speed of millimeter wave signals is equal to the speed of light, the rotation direction of the millimeter wave antenna 1 can be ignored during the time from when it transmits the millimeter wave signal to when it receives the millimeter wave signal reflected back from the obstacle. Therefore, the direction of the obstacle is the transmission direction of the millimeter wave signal, and the relative direction between the obstacle (i.e., the target object) and the electronic device can be determined.

[0032] The relative direction determination method provided in this application embodiment involves setting a rotatable millimeter-wave antenna within an electronic device. This millimeter-wave antenna is used to transmit millimeter-wave signals and receive reflected millimeter-wave signals. Based on the millimeter-wave signals, it is determined that the millimeter-wave antenna has detected a target object, and the rotation angle of the millimeter-wave antenna is determined. Based on the rotation angle of the millimeter-wave antenna, the relative direction between the target object and the electronic device can be determined, which is beneficial for the electronic device to achieve more functions.

[0033] In one embodiment, the method further includes at least one of the following:

[0034] 1) Determine the distance between the target object and the electronic device based on the time difference between the millimeter-wave signal transmitted and received by the millimeter-wave antenna.

[0035] For example, in this embodiment, the distance between the target object (the object being detected) and the electronic device is obtained by multiplying the time difference by the speed of light and then dividing by 2.

[0036] 2) Determine the material properties of the target object based on the energy and / or phase of the millimeter-wave signal transmitted and received by the millimeter-wave antenna.

[0037] This embodiment identifies the material properties of a target object by monitoring changes in relevant parameters of the reflected millimeter-wave signal, such as energy loss and phase change. For example, the energy loss range of the reflected millimeter-wave signal is: P n dB < PL < P n+1 dB, with a phase variation range of: ω n °<PC<ω n+1 ° By matching the aforementioned changes with the material property-related data in the electronic device's data storage module, the material properties of the target object can be determined, such as whether it is a human body or a metal. This determination of material properties can be performed after the millimeter-wave antenna 1 has stopped rotating. Since this action is performed electrically, its processing time should be very short, at the millisecond or even nanosecond level.

[0038] After determining the distance, material properties, or relative direction as described above, the millimeter-wave antenna 1 can continue to rotate and transmit and receive millimeter-wave signals, and then make relevant judgments and identifications on objects approaching the electronic device again. As long as the rotation speed of the millimeter-wave antenna 1 is fast enough, it can make relevant judgments on objects approaching the electronic device from different relative directions at the same time.

[0039] In one embodiment, the method further includes at least one of the following:

[0040] 1) Based on the relative direction, material properties and / or distance of the target object, determine the screen that needs to be lit or the screen that needs to be turned off, wherein the electronic device includes at least one screen.

[0041] For example, if the electronic device is a mobile phone with a dual-screen, the phone can sense and control the screen on the side closest to the human body to light up, thus realizing human-machine intelligent control to a certain extent. This example utilizes the relative direction of the target object, material characteristics (i.e., the human body), and distance.

[0042] 2) Adjust the communication performance of the communication antenna of the electronic device based on the relative direction, material properties and / or distance of the target object.

[0043] For example, in the application of antenna technology in electronic devices, the antenna module senses the material characteristics of the target object in contact with the electronic device from all directions. Then, through relevant mechanisms, the antenna module adaptively improves its performance, enriching the application scenarios of AI radio frequency signal enhancement technology, and to a certain extent, falling under the field of AI radio frequency signal enhancement technology. A specific example is reducing the transmission power of the antenna on the side of the electronic device closest to the human body, which helps reduce the impact of radiation on the human body, and so on.

[0044] In one embodiment, before rotating the millimeter-wave antenna, the method further includes: determining the wireless connection status of the electronic device; and determining that the wireless connection status matches the operating scenario requirements of the millimeter-wave antenna.

[0045] This embodiment makes the timing of the solution more reasonable by limiting the wireless connection status of the electronic device and the requirements of the operating scenario, which helps to reduce the resource consumption of the electronic device.

[0046] In one embodiment, such as Figure 3 As shown, the electronic device includes a base 5 and an electrical connector 6, the electrical connector 6 being slidably electrically connected to the base 5 to change the circuit parameter values ​​of the base 5; determining the rotation angle of the millimeter-wave antenna includes: determining the rotation angle of the millimeter-wave antenna based on the circuit parameter values ​​of the base 5 of the millimeter-wave antenna; wherein, there is a mapping relationship between multiple different circuit parameter values ​​corresponding to the base 5 and multiple different rotation angles of the millimeter-wave antenna 1.

[0047] like Figure 3 As shown, the electronic device may further include a rotating shaft 4, the bottom end of the electrical connector 6 is connected to the rotating shaft 4, the top end of the electrical connector 6 is slidably electrically connected to the first end of the base 5, the second end of the base 5 and the electrical connector 6 are both electrically connected to the circuit status module C2, and the circuit status module C2 is used to monitor the circuit parameter values.

[0048] In one embodiment, the base 5 includes a resistive element, and the circuit parameter values ​​of the base 5 include the resistance value of the resistive element, which increases as the rotation angle increases.

[0049] Figure 4This is a schematic diagram of the base 5 of the variable resistor. The resistance of this variable resistor is uniform per unit length. The total resistance of the base 5 divided by 360 is the increase in resistance of the millimeter-wave antenna 1 for every 1° rotation. Here, the negative terminal is set to the 0-resistance point, which is the 0° rotation angle of the millimeter-wave antenna 1. Therefore, the rotation angle of the millimeter-wave antenna 1 can be determined.

[0050] By measuring the change in resistance of the base 5, and then through a relevant calibration mechanism combined with the transmission direction of the millimeter-wave antenna 1, the electronic device can sense the approach of an object in its relative direction.

[0051] In one embodiment, the base 5 includes a capacitor element, and the circuit parameter values ​​of the base include the capacitance value of the capacitor element, which decreases as the rotation angle increases.

[0052] Figure 5 The diagram shows the structure of the base 5 of the variable capacitor. The total capacitance of the base 5 gradually decreases with the number of capacitors connected in series, rather than changing linearly. Therefore, a direct calibration method can be used. That is, when the rotation angle of the millimeter-wave antenna 1 is 0°, the measured capacitance is 0 pF and calibrated; when the rotation angle is 90°, the measured capacitance is K1 pF and calibrated; when the rotation angle is 180°, the measured capacitance is K2 pF and calibrated; when the rotation angle is 270°, the measured capacitance is K3 pF and calibrated; when the rotation angle is 360°, the measured capacitance is K4 pF and calibrated. Of course, the calibration granularity can be finer, for example, calibrated in 5° increments. Thus, the rotation angle of the millimeter-wave antenna 1 can be determined.

[0053] By measuring the change in capacitance of base 5, and then using a relevant calibration mechanism in conjunction with the transmission direction of millimeter-wave antenna 1, the electronic device can sense the approach of an object in its relative direction.

[0054] In one embodiment, the base includes a filter circuit, and the circuit parameter values ​​of the base include the path insertion loss value of the filter circuit, which increases with the increase of the rotation angle.

[0055] based on Figure 5In the example shown, each capacitor is replaced with a filter circuit unit consisting of resistors, inductors, and capacitors. The input and output terminals of the base 5 can be connected to the circuit status module C2 via an RF transmission line. The rotation angle of the millimeter-wave antenna 1 is calibrated by testing the insertion loss value of the entire path. For example: when the rotation angle of the millimeter-wave antenna 1 is 0°, the measured insertion loss value is 0dB and calibrated; when the rotation angle of the millimeter-wave antenna 1 is 90°, the measured insertion loss value is IL1dB and calibrated; when the rotation angle of the millimeter-wave antenna 1 is 180°, the measured insertion loss value is IL2dB and calibrated; when the rotation angle of the millimeter-wave antenna 1 is 270°, the measured insertion loss value is IL3dB and calibrated; when the rotation angle of the millimeter-wave antenna 1 is 360°, the measured insertion loss value is IL4dB and calibrated. Of course, the granularity of calibration can be finer, for example, calibrated in 5° increments.

[0056] By measuring the change in the circuit insertion loss value of the base 5, and then through a relevant calibration mechanism combined with the transmission direction of the millimeter-wave antenna 1, the electronic device can sense the approach of an object in its relative direction.

[0057] Figure 6 The diagram shows the structure of an electronic device 600 provided in an embodiment of this application. The electronic device 600 includes the following modules.

[0058] The rotatable millimeter-wave antenna 602 is used to transmit millimeter-wave signals and receive reflected millimeter-wave signals.

[0059] The monitoring module 604 is used to determine, based on the millimeter-wave signal, that the millimeter-wave antenna has detected a target object, and to determine the rotation angle of the millimeter-wave antenna.

[0060] The data processing module 606 is used to determine the relative direction between the target object and the electronic device based on the rotation angle of the millimeter-wave antenna.

[0061] In this embodiment, a rotatable millimeter-wave antenna is provided within an electronic device. This millimeter-wave antenna is used to transmit millimeter-wave signals and receive reflected millimeter-wave signals. Based on the millimeter-wave signals, it is determined that the millimeter-wave antenna has detected a target object, and the rotation angle of the millimeter-wave antenna is determined. Based on the rotation angle of the millimeter-wave antenna, the relative direction between the target object and the electronic device can be determined, which is beneficial for the electronic device to achieve more functions.

[0062] In one embodiment, the electronic device includes a base and an electrical connector, the electrical connector being slidably electrically connected to the base to change the circuit parameter values ​​of the base.

[0063] In one embodiment, the electronic device further includes a rotating shaft, the bottom end of the electrical connector is connected to the rotating shaft, the top end of the electrical connector is slidably electrically connected to the first end of the base, and the second end of the base and the electrical connector are both electrically connected to a circuit status module, which is used to monitor the circuit parameter values.

[0064] In one embodiment, the base includes a resistive element, and the circuit parameters of the base include the resistance value of the resistive element, which increases as the rotation angle increases; or, the base includes a capacitive element, and the circuit parameters of the base include the capacitance value of the capacitive element, which decreases as the rotation angle increases; or, the base includes a filter circuit, and the circuit parameters of the base include the insertion loss value of the filter circuit, which increases as the rotation angle increases.

[0065] The device 600 provided in this application embodiment can execute any of the embodiments described in the foregoing method embodiments and achieve the functions and beneficial effects of any of the embodiments described in the foregoing method embodiments, which will not be repeated here.

[0066] To illustrate in detail the method for determining relative direction and the electronic device provided in the embodiments of this application, a specific embodiment will be described below.

[0067] like Figure 7 As shown, the electronic device includes five main modules: a data storage module M1, a monitoring module M2, a data processing module M3, a control module M4, and a millimeter-wave module M5. The monitoring module M2 includes four sub-modules: an RRC monitoring module C1, a circuit status module C2, an object distance module C3, and a material properties module C4.

[0068] The data storage module M1 stores relevant data for comparison with the monitoring module M2, such as the operating scenario data and thresholds of the millimeter-wave antenna. The data processing module M3 is used to compare and analyze the data retrieved from the data storage module M1 and the monitoring module M2. The control module M4 retrieves the comparison and analysis data from the data processing module M3 and sends an operation command to the millimeter-wave module M5. After receiving the operation command from the control module M4, the millimeter-wave module M5 begins operation, monitoring the distance and characteristics of objects approaching the electronic device.

[0069] The following describes the monitoring module M2. The RRC monitoring module C1 monitors the wireless resource control status, i.e., whether the electronic device is connected to the wireless network. The circuit status module C2 monitors the circuit status of the base. The object distance module C3 monitors the distance to objects approaching the electronic device. The material properties module C4 monitors the material properties of the target object approaching the electronic device. The startup sequence of each submodule of the monitoring module M2 can be as follows: First, the RRC monitoring module C1 monitors the wireless connection status of the electronic device; second, after satisfying the first step, the circuit status module C2 begins monitoring the circuit status of the base; third, after satisfying the second step, the object distance module C3 begins monitoring the distance between the object moving towards the electronic device and the electronic device; fourth, after satisfying the third step, the material properties module C4 begins monitoring the material properties of the object approaching the electronic device. The order of steps three and four can be interchanged. Whether the conditions for each step are met is determined by the data processing module M3, and the result is then used by the detection module M2.

[0070] The following is an introduction to the M5 millimeter-wave module. Millimeter-wave modules possess the characteristics of distance measurement and energy identification, thus enabling them to test the distance to obstacles and identify the material properties of objects. For example... Figure 8 As shown, Figure 8 This is a schematic diagram of a commonly used millimeter-wave module. Its main components include a millimeter-wave antenna 1 and a millimeter-wave transceiver module 8. Of course, in other embodiments, the millimeter-wave transceiver module 8 can also be considered as part of the millimeter-wave antenna 1.

[0071] like Figure 2 As shown, the transmission direction of the millimeter-wave signal is along the line of sight of the millimeter-wave antenna 1, which is perpendicular to the two-dimensional plane composed of the millimeter-wave antenna array elements. The main components of the electronic device include: millimeter-wave antenna 1; flexible radio frequency coaxial cable 2; connecting bracket 3; rotating shaft 4; base 5; electrical connector 6, which may be a metal spring; rotary motor 7; millimeter-wave transceiver module 8; and test connection line 9.

[0072] Millimeter-wave antenna 1 and millimeter-wave transceiver module 8 work together to transmit and receive millimeter-wave signals. Millimeter-wave transceiver module 8 is fixed. Flexible RF coaxial cable 2 is used to connect millimeter-wave antenna 1 and millimeter-wave transceiver module 8. Connecting bracket 3 is used to fix millimeter-wave antenna 1 on rotating shaft 4. Rotating shaft 4 is used to drive millimeter-wave antenna 1 to rotate. Base 5 is used to identify the rotation angle of millimeter-wave antenna 1 and is fixed to the electronic device relative to millimeter-wave antenna 1. Electrical connector 6 is used for contact sliding on base 5. Rotary motor 7 is used to drive rotating shaft 4 to rotate and is mechanically connected and fixed to rotating shaft 4. Test connection cable 9 is used to connect base 5 and electrical connector 6 to circuit status module C2.

[0073] As described above, the millimeter-wave antenna 1 can rotate 360° around the rotation axis 4 in a two-dimensional plane, the base 5 can be installed in a two-dimensional plane on either side of the electronic device, and the transmission direction of the millimeter-wave antenna 1 has the ability to identify relative directions in this two-dimensional plane.

[0074] When an electronic device is in user mode, its operating steps can be as follows.

[0075] Step 1: The RRC monitoring module C1, a sub-module of monitoring module M2, starts up to monitor the wireless connection status of electronic devices, such as standard and frequency band. Its monitoring results are transmitted to data processing module M3. M3 retrieves relevant data on the operating scenario of the millimeter-wave antenna stored in data storage module M1 and compares it with the monitoring results of RRC monitoring module C1. If the results match the operating scenario of the millimeter-wave antenna, such as the connected electronic device being connected to GSM and using the Band 900 frequency band, then proceed to step 2.

[0076] Step 2: Millimeter-wave module M5 starts working. The millimeter-wave module, through the cascaded millimeter-wave transceiver module and millimeter-wave antenna, begins transmitting and receiving millimeter-wave signals. Simultaneously, control module M2 controls the rotary motor 7 to rotate, which synchronously drives the millimeter-wave antenna to rotate. Next, we proceed to step 3.

[0077] Step 3: Building upon Step 2, the circuit status module C2 of monitoring module M2 begins operation, monitoring the circuit parameters of the base in real time, such as the rotational resistance, capacitance, or insertion loss of the millimeter-wave antenna. Then proceed to Step 4.

[0078] Step 4: Based on Step 3, the object distance monitoring module C3, a sub-module of monitoring module M2, is activated to monitor the distance of the electronic device approaching the object, and then proceeds to Step 5.

[0079] Step 5: Based on Step 4, the material properties module C4 of M2 monitors the material properties of objects approaching the electronic device, and proceeds to Step 6.

[0080] Step 6: After completing the above five steps, the data processing module M3 calls the current resistance, capacitance, or insertion loss value 'a' of the base monitored by the circuit status module C2, and simultaneously calls the relevant calibration data 'b' from the data storage module. It then compares data 'a' and data 'b' to determine the relative direction of the object's approach to the electronic device, i.e., which side of the electronic device it is approaching. Based on the characteristics of the object approaching the electronic device, it performs the relevant scene-specific mechanism response actions.

[0081] It should be noted that this embodiment does not limit the order of steps four, five, and six described above.
