Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. The embodiments listed in this application may be appropriately combined with each other.
Referring to fig. 1, fig. 1 is a schematic structural diagram of an electronic device 1000 according to an embodiment of the present disclosure. The electronic device 1000 includes, but is not limited to, a device capable of transmitting and receiving electromagnetic wave signals, such as a mobile phone, a telephone, a tablet computer, a personal computer, a notebook computer, an in-vehicle device, an earphone, a wristwatch, a wearable device, a customer premises equipment (Customer Premise Equipment, CPE), and the like. In this application, the electronic device 1000 is taken as an example of a mobile phone, and other devices may refer to the specific descriptions in this application.
For convenience of description, with reference to a view angle of the electronic device 1000 in fig. 1, a width direction of the electronic device 1000 is defined as an X-axis direction, a length direction of the electronic device 1000 is defined as a Y-axis direction, and a thickness direction of the electronic device 1000 is defined as a Z-axis direction. The X-axis direction, the Y-axis direction and the Z-axis direction are perpendicular to each other. Wherein the direction indicated by the arrow is forward.
Referring to fig. 1 and 2, the electronic device 1000 includes a battery cover 320, a display screen 200, and a frame 310. The display 200 is disposed opposite to the battery cover 320, specifically, along the Z-axis direction. The frame 310 is connected between the battery cover 320 and the display screen 200. The bezel 310 is a generally rectangular frame. The battery cover 320 and the display 200 are both substantially rectangular. The battery cover 320 is covered on one side (for example, the Z-axis forward side) of the frame 310. The display 200 is covered on the other side (e.g., the Z-axis forward side) of the bezel 310. The battery cover 320, the bezel 310, and the display screen 200 may form an overall exterior surface of the electronic device 1000. In the practical design process, the battery cover 320 and the frame 310 may be an integrated structure. The display screen 200 may be a flat or curved screen. The four corners of the rim 310 may be rounded corners. The frame 310 may also have an arc-shaped structure in the thickness direction. The battery cover 320 may be a planar cover or a curved cover.
The middle plate 330 is formed in the frame 310 by injection molding, and a plurality of mounting grooves for mounting various electronic devices are formed in the middle plate 330. The middle plate 330 together with the rim 310 becomes a middle frame 340 of the electronic device 1000. After the display 200, the middle frame 340, and the battery cover 320 are closed, an accommodating space is formed on both sides of the middle plate 330. The electronic device 1000 further includes a circuit board 350, a battery 360, a camera module, a microphone, a receiver, a speaker, a face recognition module, a fingerprint recognition module, and the like, which are disposed in the accommodating space, and the device capable of implementing the basic functions of the mobile phone is not described in detail in this embodiment.
Referring to fig. 2, the electronic device 1000 further includes a distance detecting component 100 and a controller (not shown). The distance detecting assembly 100 is positioned between the battery cover 320 and the display screen 200. The distance detecting component 100 is a detecting component for detecting a distance between a subject to be detected and a position where the distance detecting component 100 is located on the electronic device 1000.
Referring to fig. 3, the distance detecting assembly 100 includes a first detecting module 110 and a second detecting module 120.
The first detection module 110 is configured to detect a first distance value according to at least a reflected signal of a subject to be detected on a side of the battery cover 320 or a side of the display screen 200.
Specifically, the first detection module 110 is configured to detect a first distance value according to a reflected signal of the to-be-detected body on the side of the battery cover 320. The first detection module 110 may be disposed at a position facing the side of the battery cover 320 or not facing the side of the battery cover 320. The first detection module 110 transmits signals to the side of the battery cover 320 and receives reflected signals from the body to be tested where the battery cover 320 is located (i.e. the first detection module 110 includes a signal transmitter and a signal receiver), or the first detection module 110 does not transmit signals and only receives reflected signals from the body to be tested where the battery cover 320 is located (i.e. the first detection module 110 includes only a signal receiver or the first detection module 110 includes a signal transmitter and a signal receiver, but only a signal receiver works).
The subject to be tested is a living body, including but not limited to, other positions of the head, hands, abdomen, legs, etc. of a human body, or other living bodies.
The first distance value may be a distance value between the main body to be measured and the first detection module 110, or a distance value between the main body to be measured and the area where the first detection module 110 is located in the battery cover 320.
The first detection module 110 receives a reflected signal from a main body to be detected on the side where the battery cover 320 is located, for example, a UWB module, a millimeter wave communication module, a rear camera module, or an infrared ranging module, which will be specifically illustrated later. Optionally, the first detection module 110 may also receive a reflected signal from a subject to be detected on the side of the display screen 200, for example, a millimeter wave gesture module, a millimeter wave communication module, a front camera module, or an infrared ranging module, which will be specifically illustrated later. Optionally, the first detection module 110 may also receive the reflected signal of the to-be-detected body on the side where the battery cover 320 is located, and also receive the reflected signal of the to-be-detected body on the side where the display screen 200 is located, for example, a combination of a UWB module and a millimeter wave gesture module, or a millimeter wave communication module, which are specifically illustrated later.
Optionally, the first detection module 110 can also receive the reflected signal from at least one side of the bezel 310, in addition to being able to receive the reflected signal from the side of the battery cover 320 and/or the display screen 200.
Referring to fig. 4, the present application relates to a plurality of orientations, so that for more clarity of description, a side of the display screen 200 is defined as a front side of the electronic device 1000, a side of the battery cover 320 is defined as a rear side of the electronic device 1000, and a side of the frame 310 is defined as a peripheral side of the electronic device 1000, wherein the frame 310 includes a first side 311, a second side 312, a third side 313, and a fourth side 314 connected in sequence. The length of the first edge 311 is less than the length of the second edge 312. The electronic device 1000 further includes a camera module. The distance between the first edge 311 and the camera module is smaller than the distance between the third edge 313 and the camera module. The side where the first side 311 is located is the top side of the electronic device 1000, the side where the second side 312 is located is the right side of the electronic device 1000, the side where the third side 313 is located is the bottom side of the electronic device 1000, and the side where the fourth side 314 is located is the left side of the electronic device 1000.
The second detecting module 120 is configured to detect a second distance value according to a coupling capacitance generated by the proximity of the main body to be detected on at least one side of the peripheral side of the frame 310.
Specifically, the second detection module 120 includes a sensing electrode. The induction electrode is an electric conductor. When the main body to be detected approaches to the sensing electrode, the sensing electrode and the surface of the main body to be detected form a coupling capacitor, so that the surface charge of the sensing electrode changes, and the approach of the main body to be detected and the distance value between the main body to be detected and the sensing electrode are detected. The second detection module 120 is configured to detect a second distance value according to a coupling capacitance generated by the proximity of the body to be detected on at least one of the top side, the left side, the bottom side, and the right side of the electronic device 1000. In other words, the sensing electrode of the second detection module 120 is disposed near at least one of the top, left, bottom, and right sides of the electronic device 1000. For example, the sensing electrode of the second detection module 120 includes, but is not limited to, a conductive portion of the frame 310, a frame radiator (the frame serves as an antenna radiator), and a bracket radiator located near the frame 310. Wherein the bracket radiator is disposed within the electronic device 1000, including but not limited to a flexible circuit board radiator molded on a flexible circuit board (Flexible Printed Circuit board, FPC), a laser direct molded radiator by laser direct molding (Laser Direct Structuring, LDS), a printed direct molded radiator by printing direct molding (Print Direct Structuring, PDS), a conductive sheet radiator, etc.
Referring to fig. 5, the controller is electrically connected to the first detection module 110 and the second detection module 120. The controller is configured to adjust an antenna transmit power of the electronic device 1000 according to the first distance value and/or the second distance value.
The controller can detect that the main body to be detected approaches from the display screen 200 side and/or the battery cover 320 side according to the first distance value detected by the first detection module 110, and can detect that the main body to be detected approaches from the frame 310 side of the electronic device 1000 according to the first distance value detected by the second detection module 120, so that the controller can distinguish whether the main body to be detected approaches from the frame 310 side of the electronic device 1000 or approaches from the display screen 200 side and/or the battery cover 320 side according to the first distance value and the second distance value, thereby pertinently reducing the transmitting power of the antenna positioned near the main body to be detected in the electronic device 1000, reducing the Specific Absorption Rate (SAR) of the electromagnetic wave radiated by the antenna positioned near the main body to be detected in the electronic device 1000, reducing the unnecessary rollbacks of the transmitting power of other antennas not near the main body to be detected in the electronic device 1000, thereby improving the intelligent SAR of the electronic device 1000 and ensuring the communication quality of the electronic device 1000.
It should be noted that, the controller may adjust the antenna transmission power of the electronic device 1000 according to the first distance value or the second distance value according to actual needs. The present application does not limit the need for the controller to obtain the first distance value and the second distance value to adjust the antenna transmission power of the electronic device 1000.
In adjusting the antenna transmit power of the electronic device 1000, including but not limited to decreasing the antenna transmit power of the electronic device 1000 or increasing the antenna transmit power.
In general technology, in order to be compatible with the problems of small number of sensors and chips and small occupied space in the electronic device 1000, it is generally impossible to effectively detect whether the electronic device 1000 is close to the frame 310 side, the display screen 200 side or the battery cover 320 side, but the antenna transmitting power in the electronic device 1000 is reduced as a whole after detecting that the electronic device 1000 is close to the human body in a general way, so that the power of the antenna within the electronic device 1000, which is far from the human body outside the "safety range", is also reduced, which causes unnecessary reduction.
According to the electronic device 1000 provided by the application, the first detection module 110 is designed to detect the first distance value according to at least the reflected signal of the main body to be detected on the side where the battery cover 320 is located or the side where the display screen 200 is located; and designing the second detection module 120 to detect a second distance value according to the coupling capacitance generated by the approach of the main body to be detected on at least one side of the peripheral side of the frame 310; the controller adjusts the antenna emission power of the electronic device 1000 according to the first distance value and/or the second distance value, so that the controller can distinguish whether the main body to be detected approaches from the side of the frame 310 of the electronic device 1000 or approaches from the side of the display screen 200 and/or the side of the battery cover 320 according to the first distance value and/or the second distance value, and accuracy of identifying the side close to the main body to be detected is improved, so that the subsequent controller can pertinently reduce the emission power of the antenna positioned close to the main body to be detected in the electronic device 1000, so as to reduce the Specific Absorption Rate (SAR) of the electromagnetic wave radiated by the antenna positioned close to the electronic device 1000, and the emission power of other antennas not close to the side in the electronic device 1000 can not retract or retract less, so that unnecessary backspacing of the emission power of other antennas not close to the side in the electronic device 1000 is reduced, thereby improving the intelligent SAR of the electronic device 1000, and ensuring the communication quality of the electronic device 1000.
The specific structure of the second detection module 120 is illustrated below.
Referring to fig. 6, the electronic device 1000 further includes an antenna assembly 400. See within the dashed box in fig. 6. The antenna assembly 400 has a plurality of radiators 410. At least a portion of the plurality of radiators 410 may be integrated with the bezel 310 (e.g., the radiators of ANTs 0-6, 8 in fig. 6) and/or at least a portion of the plurality of radiators 410 may be located within the bezel 310 and proximate to the bezel 310 (e.g., the radiator of ANT7 in fig. 6). In other words, at least a portion of the radiator 410 of the antenna assembly 400 is a rim radiator (e.g., the radiator of ANTs 0-6, 8 in fig. 6), and/or at least a portion of the radiator 410 of the antenna assembly 400 is a bracket radiator (e.g., the radiator of ANT7 in fig. 6). The second detection module 120 includes a sensing electrode (not shown, refer to the radiator 410 in fig. 6), and the sensing electrode is at least part of the radiator 410 of the antenna assembly 400, and the sensing electrode is used for detecting a distance value between the sensing electrode and the subject to be detected.
Alternatively, the radiator 410 of the antenna assembly 400 may be integrated with the battery cover 320 in addition to the bezel 310.

Further, the bracket radiator may be near four corners of the bezel 310. Part or all of the support radiator serves as a sensing electrode of the second sensing module 120.

In the fifth generation mobile communication system (abbreviated as fifth generation, 5G), a Multi-antenna system is required to satisfy multiple-input multiple-output (MIMO) operation to increase transmission bandwidth to improve data transmission speed; meanwhile, in order to consider the conditions of different use postures of the user (the main body to be tested), such as holding by one hand, holding by two hands, and placing on the body horizontally, the multi-antenna system is usually also matched with the switchable function of the transmitting antenna to ensure that good transmitting signals can be obtained under different use situations (alternatively, the transmitting antenna has only 1, and the receiving antenna has 2 or even 4 receiving antennas, including a main set receiving antenna and a diversity receiving antenna, refer to fig. 7).

Generally, the electronic device 1000 needs to consider the influence of the radiation energy of the transmitting antenna on the user, and in order to meet the security specification, the antenna transmitting energy should be retracted (the transmitting power is reduced) by the SAR value specification of each region. To avoid that the emitted energy is retracted too much, or that the user is retracted in a scenario where no retraction is required, it is conventional to use a distance sensor and whether the earpiece is open or not to determine whether the user is in a state of being close to or far from the display screen 200.
The present application describes an example in which the antenna assembly 400 shown in fig. 6 is provided in the electronic device 1000.
1. If the radiator 410 of the antenna assembly 400 is not used as the main body to be detected for proximity detection, the same back-off value is adopted for all antennas regardless of any user scene (one-hand holding, two-hand holding, flat placement on the body, etc.), and the back-off value takes the back-off value when the distance between the user and the electronic device 1000 is 0, resulting in unnecessary back-off.
2. If the radiators 410 of the first antenna unit ANT1 and the eighth antenna unit ANT8 in the antenna assembly 400 are used as the main body to be detected for approach detection, the antenna unit ANT8 can monitor the right side/top side/front side/rear side (of course, the antenna units ANT2/ANT5/ANT8 can be used as sensing devices); the antenna unit ANT1 may monitor the left/right/bottom/front/rear (of course, the antenna units ANT1/ANT4 can all be used as sensing devices).
3. On the basis of the 2 nd point, the number of the monitorable chips is limited or the antennas cannot be integrated, and at this time, the antenna units ANT0/ANT3/ANT6 antenna group does not have a function of monitoring the proximity of the main body to be detected, which results in inaccurate proximity detection of the main body to be detected in the upper left corner of the electronic device 1000.
4. On the basis of point 3, if the antenna unit ANT7 is used as a detection device for detecting the approach of the subject to be detected, the antenna unit ANT7 may sense the top/left/rear side, but due to the shielding of the display screen 200, the front side is a detection blind area of the antenna unit ANT7, and the following table 1 case (different profit cases depending on whether the hot spot position is in the blind area) may exist. The antenna units ANT0 to ANT8 are the first to eighth antenna units described above, each being a metal frame 310 antenna, and the antenna unit ANT7 is the seventh antenna unit ANT7 described above, and is a bracket antenna.

Figure BDA0003284691160000071
As can be seen from the above-mentioned study, the partial transmitting antenna group has a blind zone (for example, the blind zone appears in (front side+left side) or (front side+top side)), such as the hotspot distribution 1 in table 1, if the back-off peak appears in the monitoring blind zone, even if the antenna unit 7 is an SAR sensor, the human body approaching the blind zone cannot be detected, which leads to missed detection of the blind zone or leads to that the power back-off needs to be performed according to the safe SAR value of the blind zone when no human body approaches, which leads to unnecessary power back-off waste. In addition, as can be seen from table 1, since the frame radiator and the bracket radiator cannot monitor the front side, the rear side, the left side, the right side, the top side and the bottom side separately, the frame radiator and the bracket radiator generally fall back according to the uniform safe SAR fall back peak value during the fall back, which results in unnecessary power fall back waste on the part side where the main body to be measured is not close. In addition, because the frame radiator and the bracket radiator can not monitor the front side, the back side, the left side, the right side, the top side and the bottom side separately, whether a single hand holds a scene, a two-hand game mode or a scene of lying a body can not be judged, if the two hands hold the scene, the two hands can directly enter the human body to approach to the human body to back the transmitting power, and unnecessary power back is carried out on the part which is not held by the hands.
Based on the above-mentioned problem, the present application proposes to perform the cooperation detection by combining the first detection module 110 and the second detection module 120, so as to distinguish that the main body to be detected on the side of the frame 310 is close to the main body to be detected on the side of the display screen 200/the battery cover 320 is close to the main body to be detected. Through the cooperation of the detection devices on the first detection module 110, which are more located at different sides, and the cooperation of the detection devices on the second detection module 120, which are more located at different sides, the four sides, the five sides and the six sides of the electronic device 1000 can be separately detected, so that the near side of the main body to be detected can be accurately detected, the differentiated power backspacing can be performed on the near side, the power backspacing value can be adjusted in real time according to the distance value, so that the stepping power backspacing can be formed, and the waste of the power backspacing can be reduced under the condition that the SAR value is ensured to be within the safety standard.
The specific structure of the first detection module 110 is illustrated in the following drawings.
Referring to fig. 8, the first detection module 110 includes at least one of an antenna module 500, a camera module 600 and an infrared ranging module 700. Of course, the first detecting module 110 may be a plurality of antenna modules 500 for detecting the proximity of the main body to be detected in different directions and different areas. The first detection module 110 may also be a combination of a plurality of antenna modules 500 and at least one camera module 600, or the first detection module 110 may also be a combination of a plurality of antenna modules 500 and at least one infrared ranging module 700, or the first detection module 110 may also be a combination of a plurality of antenna modules 500 and at least one camera module 600, at least one infrared ranging module 700. The first detection module 110 is specifically illustrated by the following embodiments.
In a first embodiment of the first detection module 110, the first detection module 110 includes an antenna module 500. The reflected signal is an electromagnetic wave signal. Specifically, the first detection module 110 emits an electromagnetic wave signal towards the outside of the electronic device 1000 when in operation, so as to communicate or interact with an external base station or other devices. In other words, the electromagnetic wave signal emitted by the first detection module 110 is used for communication or interaction with a user. In this application, when the electromagnetic wave emitted by the first detection module 110 has a main body to be detected in a range of the electromagnetic wave, the electromagnetic wave signal emitted by the first detection module 110 is received by the first detection module 110 after being reflected by the main body to be detected. The first detection module 110 may determine the direction of the to-be-measured body according to the range of the electromagnetic wave radiated by the first detection module 110, for example, the first detection module 110 radiates the electromagnetic wave toward the battery cover 320, and then the first detection module 110 may determine that the to-be-measured body is located at the battery cover 320 according to the received electromagnetic wave signal reflected by the to-be-measured body. Taking the first detection module 110 radiating electromagnetic waves toward the battery cover 320 as an example, the first detection module 110 may obtain a first distance value between the main body to be measured and the battery cover 320 according to the flight time of the transmitted electromagnetic wave signal and the received electromagnetic wave signal.
The first detection module 110 sends the first distance value to the controller, the controller compares the first distance value with a preset distance, and if the first distance value is smaller than or equal to the preset distance, the controller determines that the main body to be detected is located in the SAR reducing range of the battery cover 320 side and performs intelligent SAR reducing according to a preset SAR reducing scheme. Specific preset SAR reduction schemes are described in detail below. Thus, the intelligent SAR reduction is realized when the main body to be detected approaches.
Optionally, the electromagnetic wave signal emitted by the first detection module 110 may determine the subject to be detected as a living body. Specifically, the biological detection signal corresponding to the main body to be detected is detected by electromagnetic wave signals and corresponds to information related to biological vital signs, such as respiration related information and/or heartbeat related information. The first detection module 110 determines that the subject to be detected is a living body by detecting that the reflected signal carries information related to a biological vital sign. And adjusting the antenna power according to the comparison of the first distance value and the preset distance.
The position, the antenna type, the transceiver frequency band, etc. of the first detection module 110 are not specifically limited. Optionally, the first detection module 110 includes, but is not limited to, a millimeter wave communication module, a millimeter wave gesture module, a UWB module, etc., and of course, the first detection module 110 may also be a Wi-Fi antenna, a bluetooth antenna, a GPS antenna, a 4G/5G communication antenna, etc. It is only required that the first detection module 110 has both transmitting electromagnetic wave signals and receiving electromagnetic wave signals.
It will be appreciated that the electronic device 1000, such as a cell phone, is originally provided with an antenna module 500 for communication or signal interaction.
The antenna module 500 originally used for communication or signal interaction in the electronic equipment 1000 is utilized to carry out the close detection of the main body to be detected, a new detection device is not required to be additionally added, the cost of the electronic equipment 1000 is reduced, the internal space of the electronic equipment 1000 is prevented from being enlarged, and the more accurate detection of the direction of the main body to be detected can be realized by combining the second detection module 120.
In the first embodiment of the antenna module 500, referring to fig. 9, the antenna module 500 at least includes a millimeter wave module 510. Of course, the antenna module 500 may also include Wi-Fi antennas, bluetooth antennas, GPS antennas, 4G/5G communication antennas, and the like.
Referring to fig. 10a, 10b and 11, the millimeter wave module 510 at least includes a plurality of millimeter wave radiators 511. Of course, millimeter-wave module 510 may also include millimeter-wave transceiver chips, feeds, matching networks, and the like. The millimeter wave transceiver chip is disposed on the circuit board, the feed source is electrically connected to the millimeter wave transceiver chip, and the matching network may be disposed on the substrate or the circuit board and electrically connected to the millimeter wave radiator 511. Millimeter wave radiator 511 is provided on the substrate. The plurality of millimeter wave radiators 511 are arranged in a regular manner. Millimeter wave (millimeter wave) is an electromagnetic wave with a wavelength of 1 to 10 mm. Millimeter waves have extremely wide bandwidths. Millimeter wave frequencies are generally considered to range from 26.5 to 300GHz. The beam of millimeter waves is narrow. The beam of millimeter waves is much narrower than the beam of microwaves at the same antenna size, so that small objects that are closer together can be resolved or the details of the objects can be observed more clearly. The millimeter wave module 510 has better directivity and higher gain when forming beam forming, can perform better communication, and can more accurately detect that the main body to be detected is close in the radiation range.
The millimeter wave radiators 511 can transmit and receive millimeter wave signals toward the side of the display screen 200 to detect that the body to be measured on the side of the display screen 200 is close. The millimeter wave radiators 511 can also transmit and receive millimeter wave signals towards the side where the battery cover 320 is located, so as to detect that the body to be detected on the side of the battery cover 320 is close. The plurality of millimeter wave radiators 511 may also transmit and receive millimeter wave signals toward at least one of the peripheral sides of the bezel 310 to detect that the subject to be measured is approaching at least one of the peripheral sides of the bezel 310. The detection of at least one of the display 200 side, the battery cover 320 side, and the peripheral side of the bezel 310 may be detected by one millimeter wave antenna module 500 or may be detected by a plurality of millimeter wave antenna modules 500. When the detection of at least one of the display 200 side, the battery cover 320 side, and the peripheral side of the bezel 310 is detected by one millimeter wave antenna module 500, the millimeter wave antenna module 500 may be disposed on a rotating bracket to change the direction in which it receives and transmits millimeter wave signals, thereby improving the detection range of the millimeter wave antenna module 500.
In the first embodiment of the millimeter-wave module 510, referring to fig. 10a and 10b, the millimeter-wave module 510 is a millimeter-wave communication module 510a. The electromagnetic wave signal received and transmitted by the millimeter wave communication module 510a is used for communication with a base station or the like, and in this embodiment, the electromagnetic wave signal received and transmitted by the millimeter wave communication module 510a is also used for detecting the approach of the subject to be detected (i.e. detecting the first distance value described above).
Fig. 12 a-12 g are schematic diagrams of beam forming switching of millimeter wave communication module 510a at different angles. As can be seen from fig. 10b, the radiator 410 of the millimeter-wave communication module 510a is an array of 1*4 radiators 410. The main communication range of the millimeter wave communication module 510a is +y hemisphere. The pattern diagrams, such as plates, after beamforming at different angles and the variation of the plates between different angles are shown in fig. 12 a-12 g. As can be seen from fig. 12a to 12g, as the gradient of the phase P (the phase P angle gradient is-45 °, -30 °, -15 °, -0 °, +15 °, +30°, and +45°, respectively, shown in fig. 12a to 12 g) changes, the beam of the millimeter wave communication module 510a is deflected in the X-axis direction, that is, the beam is scanned. Wherein, in connection with fig. 13, the angular range of the beam scanning covers at least-50 ° to +50°, wherein the gain reaches 8 to 10dBi. It is illustrated that millimeter-wave communication module 510a has a greater beam coverage and a better antenna gain within the greater beam coverage.
As can be seen from fig. 12a to 12g, the coverage area of the single beam in the +x to-X direction is larger, which means that when the millimeter wave communication module 510a is mounted at the edge end of the electronic device 1000 and applied to the proximity recognition of the subject to be detected, the millimeter wave communication module 510a can recognize the proximity of the subject to be detected on at least three sides. For example, when millimeter-wave communication module 510a is oriented toward first side 311, millimeter-wave communication module 510a may detect first side 311, display 200 near first side 311, and battery cover 320 near first side 311. Thus, by adopting the millimeter wave communication module 510a to approach the main body to be detected, compared with the case that three antenna modules 500 are all provided, the detection range can be increased, the number of the antenna modules 500 to be provided can be reduced, the approach detection precision of the main body to be detected can be improved, and the occupation space of the distance detection assembly 100 in the electronic device 1000 can be reduced.
In the first embodiment of the millimeter wave radiator 511, referring to fig. 11, the plurality of millimeter wave radiators 511 includes a plurality of first radiator arrays 511a arranged in an array. The first radiator array 511a transmits and receives millimeter wave signals to and from the side of the display screen 200, the side of the battery cover 320, or at least one side of the peripheral side of the frame 310.
Optionally, the first radiator array 511a is disposed on the carrying surface of the substrate, and the first radiator array 511a performs beam scanning on the carrying surface of the substrate. The bearing surface of the substrate may be disposed towards the side of the display screen 200, so that the first radiator array 511a transmits and receives millimeter wave signals towards the side of the display screen 200, so as to detect that the main body to be tested on the side of the display screen 200 approaches. Of course, in other embodiments, the first radiator array 511a may also perform beam scanning in a direction perpendicular to the normal of the bearing surface on the substrate. The bearing surface of the substrate may face the frame 310, so that the first radiator array 511a transmits and receives millimeter wave signals toward the side of the display screen 200, so as to detect that the to-be-detected body on the side of the display screen 200 approaches. The first radiator array 511a may transmit and receive millimeter wave signals toward the battery cover 320 and the frame 310, which are referred to the above embodiments and will not be described herein.
The first radiator array 511a is made of a conductive material, and the specific material is not limited herein. When the millimeter wave communication module 510a is mounted in the electronic device 1000 and faces the side of the display screen 200, that is, when the first radiator array 511a transmits and receives millimeter wave signals to and from the side of the display screen 200, the position of the first radiator array 511a corresponds to an area where no metal shielding is provided. For example, referring to fig. 14, the display screen 200 has a display area 210 for displaying an image and a non-display area 220 not used for image display, and the non-display area 220 may be a black border area, an open area, a notch area, or the like of the display screen 200. Referring to fig. 14, at least a portion of the first radiator array 511a is located in the non-display area 220, so that electromagnetic wave signals received and transmitted by the first radiator array 511a are not blocked by the display screen 200, and can be smoothly interacted with the outside.
Referring to fig. 15, when the millimeter-wave communication module 510a is mounted in the electronic device 1000 toward the battery cover 320, the positions of the plurality of first radiator arrays 511a of the millimeter-wave communication module 510a correspond to the areas where the metal shielding is not provided.
It is understood that the plurality of first radiator arrays 511a may be arranged along a linear array or may be arranged along an array of a plurality of rows and a plurality of columns. The first radiator array 511a may be a patch radiator. The shape of the first radiator array 511a includes, but is not limited to, rectangular, circular, cross-shaped, square ring, circular ring, and the like.
The number of millimeter-wave communication modules 510a in the present embodiment may be one, two, or more, wherein one millimeter-wave communication module 510a may be disposed toward the display 200 side or the battery cover 320 side. Referring to fig. 14 and 15 together, two millimeter-wave communication modules 510a may be disposed toward the display screen 200 side and the battery cover 320 side, respectively, or, referring to fig. 14, two millimeter-wave communication modules 510a may be disposed toward the display screen 200 side near the first side 311 and the display screen 200 side near the third side 313, respectively, or, referring to fig. 15, two millimeter-wave communication modules 510a may be disposed toward the battery cover 320 side near the first side 311 and the battery cover 320 side near the third side 313, respectively. Of course, the number of millimeter-wave communication modules 510a in the present embodiment may be four, and referring to fig. 14 and 15, the millimeter-wave communication modules may be disposed toward the position of the display 200 near the first side 311, the position of the display 200 near the third side 313, the position of the battery cover 320 near the first side 311, and the position of the battery cover 320 near the third side 313, respectively.
In this way, by setting the plurality of millimeter wave communication modules 510a, on one hand, the millimeter wave communication coverage of the electronic device 1000 is improved, on the other hand, the specific direction that the electronic device 1000 detects that the main body to be detected approaches through the millimeter wave communication modules 510a can be improved, the intelligent SAR reduction is realized, and unnecessary power backspacing is reduced.
In the embodiment of the second millimeter wave radiator 511, different from the embodiment of the first millimeter wave radiator 511 is: referring to fig. 11, the plurality of millimeter wave radiators 511 includes a substrate, a first radiator array 511a and a second radiator array 511b. The substrate includes a first bearing surface 512 (X-Y plane) and a second bearing surface 513 (X-Z plane) that are disposed to intersect (e.g., vertically).
Optionally, the second radiator array 511b and the first radiator array 511a are disposed on different surfaces of the substrate. The second radiator array 511b and the first radiator array 511a respectively transmit and receive millimeter wave signals on different sides of the electronic device 1000. For example, the second radiator array 511b and the first radiator array 511a transmit and receive millimeter wave signals to and from the side of the display screen 200 and the side of the battery cover 320, transmit and receive millimeter wave signals to and from at least one side of the peripheral side of the bezel 310 and the side of the display screen 200, or transmit and receive millimeter wave signals to and from at least one side of the battery cover 320 and the peripheral side of the bezel 310, respectively.
Specifically, referring to fig. 11, the first radiator array 511a and the second radiator array 511b are illustrated on the same bearing surface (the first bearing surface 512) of the substrate. The first radiator array 511a includes a plurality of patch radiators arranged in an array. The second radiator array 511b includes a plurality of dipole radiators arranged in an array. Wherein the array arrangement comprises a linear array or an array of rows and columns. The direction of each dipole radiator is the normal direction (i.e., + Y direction) of the second bearing surface 513. The direction of the dipole radiator is the direction of the oscillator of the dipole radiator.
Specifically, referring to fig. 11, a plurality of patch radiators are linearly arranged along a first direction, for example 1*4. The first direction is, for example, the +x direction. The plurality of dipole radiators are arranged in a linear manner along the first direction, for example 1*4. Wherein the symmetrical dipoles of each dipole radiator are aligned along a first direction and the symmetrical dipoles face a second direction. The second direction is the +y direction. The patch radiator and the dipole radiator respectively transmit and receive millimeter wave signals to different sides of the electronic device 1000. The plurality of dipole radiators may be beamformed in the +y direction. The plurality of patch radiators may be beamformed in the-Z direction.
Referring to fig. 11, the patch radiator has a square shape. The patch radiation is a dual polarized radiator. Wherein, P2, P3, P6, P7 are feeding points of the four patch radiators in the vertical polarization direction. And feeding points in the horizontal polarization directions of the four patch radiators P1, P4, P5 and P8 respectively. Pa, pb, pc, pd are the feed points of the four dipole radiators in the vertical polarization direction, respectively. Pe, pf, pg, ph are the feed points of the four dipole radiators in the horizontal polarization direction, respectively.
The above is an example in which the plurality of millimeter wave radiators 511 are beamformed in the +y direction and beamformed in the-Z direction, and the +y direction and the-Z direction may be the side of the bezel 310+the display screen 200, or the side of the bezel 310+the battery cover 320. Of course, another row of dipole radiators arranged in array can be arranged on the other side of the patch radiator on the bearing surface of the substrate, the dipole radiators on two sides of the patch radiator are symmetrically arranged, and the added dipole radiator is subjected to beam forming in the-Y direction. Thus, the two rows of dipole radiators and the patch radiator therebetween can be beam-formed toward the three sides, and the approach of the main body to be tested on at least three sides of the electronic device 1000 can be detected by one millimeter wave module 510.
Alternatively, the first radiator array 511a and the second radiator array 511b are illustrated on different bearing surfaces of the substrate. For example, the first and second arrays of radiators 511a, 511b are located on the first and second bearing surfaces 512, 513, respectively. Wherein, the first radiator array 511a and the second radiator array 511b may be patch radiators. The first radiator array 511a is beamformed on a first bearing surface 512. The second radiator array 511b is beamformed on the second bearing surface 513. By arranging the first bearing surface 512 and the second bearing surface 513 of the substrate to face the side where the display screen 200 is located and the side where the battery cover 320 is located, the second radiator array 511b and the first radiator array 511a can face the side where the display screen 200 is located and the side where the battery cover 320 is located respectively to transmit and receive millimeter wave signals, and the transmitting and receiving of millimeter wave signals on other sides can also be realized by arranging the orientation of the substrate, which is not repeated here.
The proximity detection of the body under test on multiple sides within the electronic device 1000 is formed in conjunction with the plurality of millimeter-wave communication modules 510 a.
In a second embodiment of the millimeter wave module 510, referring to fig. 16, the millimeter wave module 510 is a millimeter wave gesture module 510b. The millimeter wave gesture module 510b is configured to gesture-identify and detect the first distance value. Specifically, the millimeter wave gesture module 510b in the electronic device 1000 can perform gesture recognition by receiving and transmitting millimeter wave signals, and the electronic device 1000 performs related feedback operations according to the gesture of the user, for example, optionally starting and stopping at intervals through gesture operations, switching music, adjusting volume, and the like. In this embodiment, the millimeter wave gesture module 510b can also receive the millimeter wave signal reflected by the main body to be detected, and detect whether the main body to be detected is close to the electronic device 1000 and the specific azimuth of the main body to be detected according to the flight time of the millimeter wave signal, so that the multi-purpose of the millimeter wave gesture module 510b is realized.
Referring to fig. 16, the radiator of the millimeter wave gesture module 510b transmits and receives millimeter wave signals to and from the side of the display screen 200. Specifically, the radiator of the millimeter wave gesture module 510b is disposed on a bearing surface of the substrate, where the bearing surface of the substrate faces the side of the display screen 200.
Referring to fig. 17, the display screen 200 includes a display area 210 and a non-display area 220. The radiator of the millimeter wave gesture module 510b is at least partially located in the non-display area 220. The non-display area 220 is described in detail above and will not be described again here. For example, the radiator of the millimeter wave gesture module 510b includes one transmitting patch radiator and three receiving patch radiators, wherein the three receiving patch radiators are arranged along two perpendicular (or intersecting) directions to realize single-point or multi-point gesture recognition.
The millimeter wave gesture module 510b for gesture recognition in the electronic device 1000 is further used for recognizing the approach of the main body to be detected, the millimeter wave gesture module 510b is arranged on the side of the display screen 200, the approach detection of the main body to be detected on the side of the display screen 200 can be detected, and in combination with the millimeter wave communication module 510a, the approach of the main body to be detected on the side of the display screen 200, the side of the frame 310 and the side of the battery cover 320 can be accurately detected, and the intelligent SAR reduction can be performed on the antenna on the side close to the main body to be detected in a targeted manner, so that unnecessary power reduction is avoided.
It is understood that the number of millimeter wave gesture modules 510b may be one, two, three, four, etc. The millimeter wave gesture modules 510b are disposed on different sides of the frame 310, respectively, to detect which side is approaching the display screen 200. For example, referring to fig. 17, two millimeter wave gesture modules 510b are close to the first edge 311 and the third edge 313, respectively, so that a subject to be tested can be detected more accurately by approaching the display screen 200 from the first edge 311 or approaching the display screen 200 from the third edge 313. For example, a two-hand grip scene from the first side 311 and the third side 313 can be clearly detected.
In a second embodiment of the antenna module 500, referring to fig. 9, the antenna module 500 includes a UWB module 520. The UWB module 520 is configured to perform positioning detection and detect the first distance value (i.e., a distance between the subject to be detected and the side of the UWB module 520). Specifically, the electronic device 1000 may be used as an active object searching device or an apparatus to be positioned, and the UWB module 520 in the electronic device 1000 is configured to cooperate with UWB antennas in other devices through UWB signals to achieve a positioning effect.
In this embodiment, referring to fig. 18 and 19, the UWB module 520 includes a plurality of UWB radiators 521. The plurality of UWB radiators 521 are arranged in at least two intersecting directions.
The UWB radiators 521 transmit/receive UWB signals to/from the battery cover 320. Optionally, the plurality of UWB radiators 521 are disposed toward the side of the battery cover 320. The UWB signal emitted by the UWB module 520 in the electronic device 1000 can also be used as a detection device when the body to be detected on the side where the battery cover 320 is located approaches, thus realizing one object and multiple purposes of the UWB module 520.
In a second embodiment of the first detection module 110, referring to fig. 8, 20 and 21, the first detection module 110 includes a camera module 600. The reflected signal is a visible light signal. The camera module 600 includes at least one of a front camera and a rear camera. When the camera module 600 detects that the main body to be detected is located within the distance threshold range through the shot image (or in combination with other sensors such as gyroscopes), the camera module 600 sends a feedback signal to the controller, and the controller determines that the main body to be detected approaches the electronic device 1000 from the side of the display screen 200 or the side of the battery cover 320 according to the feedback signal and the position of the camera module 600, so as to intelligently reduce the SAR value of the main body to be detected.
In this embodiment, the camera module 600 that is originally used for capturing images by using the electronic device 1000 is used for capturing images, so as to detect the approach of the main body to be detected, so that the accuracy of the detection position of the main body to be detected can be further improved, and meanwhile, no additional detection device is required.
In general, the front camera and the rear camera are respectively located at a position close to the first side 311 on the display screen 200 side and a position close to the first side 311 on the battery cover 320 side. When the main body to be detected is detected through the camera module 600, the main body to be detected can be conveniently determined to be close to the first edge 311, particularly in a scene of holding the two-hand transverse screen, the user can hold the first edge 311, then the camera module 600 or the rear camera module 600 detects the close of the main body to be detected, and then the judgment of the scene of holding the two-hand transverse screen can be assisted.
In other embodiments, the camera module 600 is a rotatable camera, that is, the camera module 600 may rotate around the X-axis direction, when the camera module 600 is in the non-rotated state, it faces the first side 311 when rotating by about 90 degrees, and faces the display screen 200 side when rotating by about 180 degrees, so that whether the display screen 200 side approaches the body to be tested at the first side 311, the battery cover 320 side approaches the body to be tested at the first side 311, or the body to be tested at the first side 311 approaches the body to be tested.
Referring to fig. 22, the electronic device 1000 further includes an ambient light detection module 800. The controller is also electrically connected to the ambient light detection module 800 and the camera module 600. The controller is further configured to control the camera module 600 to detect the first distance value when the intensity of the light detected by the ambient light detection module 800 is greater than a preset intensity value. That is, the controller controls the camera module 600 to detect the first distance value when the intensity of the ambient light is relatively strong (e.g., in daytime), so as to improve the detection success rate of the camera module 600 for detecting that the subject to be detected approaches.
In a third embodiment of the first detection module 110, referring to fig. 8 and 23, the first detection module 110 includes an infrared ranging module 700. The first detection module 110 faces to the side where the display screen 200 is located or the side where the battery cover 320 is located. Of course, the first detecting module 110 faces to the side of the frame 310 or the battery cover 320.
Referring to fig. 23, the infrared ranging module 700 may be disposed in the non-display area 220 of the display screen 200 as a human body proximity sensor, and may be used as a sensing device for adjusting the off-screen or on-screen of the display screen 200 during a call. The reflected signal received by the infrared ranging module 700 is an infrared light signal. Of course, the infrared ranging module 700 may also be disposed on the side of the frame 310 or the side of the battery cover 320, and may also be used as a detection device for detecting whether the main body to be detected approaches on the side of the frame 310 or the side of the battery cover 320.
By arranging the detection device originally having the function of the detection device to be used for detecting whether the detection device is close to the main body to be detected or not, the accuracy of the detection position of the main body to be detected can be further improved, and meanwhile, the detection device is not required to be additionally arranged.
In other embodiments, the infrared ranging module 700 may also be an infrared thermal sensing detection to detect whether a subject to be measured is approaching that is in line with the temperature of the human body.

Referring to fig. 24 and 25, the first detecting module 110 includes a first detector 110a and a second detector 110b near the first edge 311. The first detector 110a is configured to detect a distance value between the side of the display screen 200 and the subject to be tested. Optionally, the first detector 110a faces the side of the display screen 200, and of course, in other embodiments, the first detector 110a may not face the side of the display screen 200, for example, the carrying surface of the dipole radiator array may not face the side of the display screen 200, and it is also possible to implement detection of a distance value between the side of the display screen 200 and the subject to be tested. Referring to fig. 8 and 9, the first detector 110a includes, but is not limited to, any one of a millimeter wave gesture module 510b, a millimeter wave communication module 510a, a camera module 600, an infrared ranging module 700, etc. The second detector 110b is configured to detect a distance value between the side of the battery cover 320 and the main body to be detected. Optionally, the second detector 110b faces the side of the battery cover 320, and of course, in other embodiments, the second detector 110b may not face the side of the battery cover 320. The second detector 110b includes, but is not limited to, any one of a UWB module 520, a millimeter wave communication module 510a, a camera module 600, an infrared ranging module 700, and the like.

The fourth detector 110d includes, but is not limited to, any of a UWB module 520, a millimeter wave communication module 510a, a camera module 600, an infrared ranging module 700, and the like.
The radiators 410 located on the first side 311, the second side 312, the third side 313 and the fourth side 314 can be used as sensing electrodes for proximity detection of the main body to be detected on the first side 311, the second side 312, the third side 313 and the fourth side 314, respectively.
Referring to fig. 24 and 25, the controller is configured to adjust the transmitting power of the first antenna set 400a, the second antenna set 400b and the fourth antenna set 400d according to the distance values of the to-be-measured body detected by the first detector 110a and the second detector 110b, and the distance values of the to-be-measured body detected by the sensing electrodes of the second detection module 120 located on the first side 311, the second side 312 and the fourth side 314, respectively.
By setting the first detector 110a, the second detector 110b, and combining with the detection of the second detection module 120 on the peripheral side of the frame 310, the approach of the electronic device 1000 to the main body to be detected in the top space can be accurately detected, and the transmitting power of the first antenna group 400a, the second antenna group 400b, and the fourth antenna group 400d can be adjusted according to the position of the main body to be detected, and because the third antenna group 400c is located on the side far from the main body to be detected, no adjustment is needed, and unnecessary power backoff is reduced.
It should be noted that, adjusting the transmission power of a certain antenna group means adjusting the power value of the side where the antenna group is located to reduce or increase the SAR of the side, but the application is not limited to adjusting the transmission power of all antennas or part of the antennas of the side where the antenna group is located, and the reduction values of the transmission powers of the plurality of antennas of the side where the antenna group is located are not limited, and may be the same or different, so long as the overall SAR value of the side or the area where the electrical measurement main body is located is within the safety specification.
Referring to fig. 24 and 25, the controller is further configured to adjust the transmitting powers of the second antenna group 400b, the third antenna group 400c and the fourth antenna group 400d according to the distance values of the to-be-measured body detected by the third detector 110c and the fourth detector 110d, and the distance values of the to-be-measured body detected by the sensing electrodes of the second side 312, the third side 313 and the fourth side 314 on the second detection module 120, respectively.
By setting the third detector 110c, the fourth detector 110d, and combining with the detection of the second detection module 120 on the peripheral side of the frame 310, the approach of the electronic device 1000 to the main body to be detected in the bottom space can be accurately detected, and the transmitting power of the third antenna group 400c, the second antenna group 400b, and the fourth antenna group 400d can be adjusted according to the position of the main body to be detected, and because the first antenna group 400a is located on the side far from the main body to be detected, no adjustment is needed, and unnecessary power backoff is reduced.
Referring to fig. 24 and 25, the controller is configured to detect that the object to be measured approaches according to the fourth detector 110 d. The first detector 110a, the second detector 110b, and the third detector 110c do not detect that the subject to be measured is approaching. That is, the position of the battery cover 320 near the bottom side detects the approach of the body to be measured, and the display 200 side does not detect the approach of the body to be measured at the position of the battery cover 320 near the top side, and it is determined that the electronic apparatus 1000 is in the one-hand holding state. When it is determined that the electronic device 1000 is in the one-hand holding state, the powers of the first antenna unit ANT1 and the fourth antenna unit ANT4 in fig. 25 may be reduced, the powers of the second antenna unit ANT2 and the 0 th antenna unit ANT0 may be reduced, and since the distance between the second antenna unit ANT2 and the subject to be measured is greater than the distance between the first antenna unit ANT1 and the subject to be measured, the power backoff value of the second antenna unit ANT2 is smaller than the power backoff value of the first antenna unit ANT1, the power backoff value of the 0 th antenna unit ANT0 is smaller than the power backoff value of the first antenna unit ANT1, the fifth antenna unit ANT5, the seventh antenna unit ANT7, and the sixth antenna unit ANT6 may not perform backoff, or the backoff values may not be performed for the eighth antenna unit ANT8 and the third antenna unit ANT 3. Thus, the stepping power backspacing according to the distance between the main body to be measured is realized. The above is the power adjustment of the main body to be measured approaching from the bottom side, and the approaches of the main body to be measured from the top side, the left side and the right side can refer to the adjustment modes. When the main body to be tested approaches from the side of the display screen 200 (including near the top side and near the bottom side), the power of the 0 th to eighth antenna units ANT8 can be retracted together.
Of course, in other embodiments, when it is detected that the electronic device 1000 is in a single-hand holding state and other parts of the human body are not close to the electronic device 1000, the power of the antenna unit may not be reduced, so as to ensure the communication quality of the electronic device 1000.
Referring to fig. 25, the first detecting module 110 further includes a fifth detector 110e. The fifth detector 110e is configured to detect a distance value between the side of the battery cover 320 and the main body to be detected. Optionally, the second detector 110b faces the side of the battery cover 320, and of course, in other embodiments, the second detector 110b may not face the side of the battery cover 320. The fifth detector 110e is located between the first side 311 and the third side 313.
Referring to fig. 24 and 25, the controller is further configured to detect that the object to be measured approaches according to the second detector 110b and the fourth detector 110 d.
