Technical Field

The present disclosure relates to the field of electronic devices, but not limited to the field of electronic devices, and more particularly to an electronic device.

Background

The communication terminal is provided with an antenna, and the function of a target object close to the antenna is damaged due to the fact that the electromagnetic wave Absorption Rate (SAR) of the antenna is too high. When the antenna of the electronic equipment is arranged, the detection device is arranged to detect the electromagnetic wave absorption ratio corresponding to the antenna, so that the conduction power of the antenna is reduced when the SAR is too high. In practical application, a large number of antennas are often dispersedly arranged in electronic equipment according to communication requirements, the layout is unreasonable, the detection range is small, and the accuracy of the measured SAR value is low. In the related art, the target object cannot be accurately protected according to the measured SAR value, and the protection performance is poor.

As shown in fig. 1, an embodiment of the present disclosure provides an electronic device, including:

a body 10;

an antenna assembly 20 comprising at least two first type antennas 201 arranged on said body diagonal 10;

a sensor 30 connected to the first type antenna 201; for obtaining a capacitance value between the antenna and a target object;

a processor 40 connected to the sensor 30; for determining the transmission power of the antenna from the capacitance value.

In some embodiments, the electronic device may be a mobile phone, a computer, a wearable device, or other electronic devices that require an antenna for transmitting and receiving signals.

In one embodiment, as shown in fig. 2, the first type antenna 201 is diagonally disposed on the first diagonal 101 and the second diagonal 102 of the body, respectively.

In this way, by arranging the first type antenna on the pairs of opposite corners of the body 10, the plurality of sensors associated with the first type antenna can detect the capacitance between the target object and the first type antenna 201 in a wider spatial range based on the first type antenna, and the detection accuracy is high.

In some embodiments, the body 10 of the electronic device is a polygonal body structure. Specifically, the structure can be a cuboid, a cube and other irregularly-shaped polygonal structures. Here, the polygonal body structure has at least two opposite corners, and the opposite corners may be two symmetrical corners on the electronic device body 10; alternatively, the opposite corners are two non-adjacent corners of the electronic device body 10. For example, the diagonal is a first diagonal 101 and a second diagonal 102 as shown in fig. 2.

In one embodiment, the diagonal angles on the body 10 of other configurations are not limited to the first diagonal angle 101 and the second diagonal angle 102 as shown in fig. 2.

In one embodiment, the antenna assembly 20 includes a first type of antenna 201 diagonally disposed on the polygon structure. Here, the first type antenna 201 may be a Printed Circuit Board (PCB) type antenna, a Surface Mount Technology (SMT) type antenna, an external rod type antenna, and a Flexible Printed Circuit (FPC) antenna; alternatively, the first type antenna 201 is a metal middle frame antenna. In one embodiment, the electronic device further includes a frame 50 (shown in fig. 3) disposed on a side of the electronic device body; the first type antenna is arranged on the frame and is grounded through a capacitor. The frame 50 is a frame arranged around the body and used for protecting the body. The bezel 50 may be a closed bezel; alternatively, the bezel 50 may be a bezel provided with an open surface, and the open surface of the bezel 50 may be opposite to a side surface of the electronic device body.

In one embodiment, the electronic device further comprises a bezel 50 disposed at a side of the body; the first type antenna 201 is suspended inside the frame 50. The suspension arrangement may be such that the first type antenna 201 is not directly grounded. For example, the first type antenna 201 suspended inside the bezel 50 may be grounded through a contact. Therefore, the first-type antenna 201 is not directly grounded, short circuit of the first-type antenna 201 is avoided, and rapid signal transceiving of the first-type antenna 201 in a non-blocking space is facilitated.

For example, if the electronic device is approximately rectangular, the upper side, the lower side, the left side and the right side of the electronic device are respectively provided with a frame 50. The frame 50 is hollow inside, and the first type antenna can be suspended inside the frame. Here, the frame may be a non-metal frame, for example, the frame may be a plastic frame; alternatively, the bezel may be a metal bezel.

In some embodiments, the body 10 of the electronic device has a plurality of rims 50, wherein each two rims 50 define a corner; the first type antenna 201 of the antenna assembly 20 may be diagonally disposed at a predetermined number of corners of the body 10. Illustratively, the electronic device is a mobile phone, and the mobile phone has 4 frames, and each two frames define a corner therebetween. For example, as shown in FIG. 3, two borders 50 define a first diagonal 101.

In one embodiment, the first type antenna 201 may be disposed on two first opposite corners 101 on the handset body 10; alternatively, the first type antennas 201 are respectively disposed on two second opposite corners 102 on the body 10. Here, the first type antenna 201 may be an "L" type antenna, and in this case, the first type antenna 201 may be distributed in two frames corresponding to the located corners. Therefore, the first type antennas arranged on the opposite corners of the body can be distributed on each frame of the electronic equipment, and the sensing range of the sensor connected with the first type antennas is large.

In some embodiments, the handset has a predetermined number of corners, the first type antenna 201 being disposed at each corner indicated by the predetermined number of corners. For example, the electronic device is a mobile phone, and as shown in fig. 2, the first type antennas 201 may be respectively disposed on two first opposite corners 101 and two second opposite corners 102 of the mobile phone body 10.

In some embodiments, the body 10 has a first side and a second side, and the first-type antenna 201 is disposed on the first side and the second side of the body 10, respectively. In particular, the first face may be a front face of the body, and the second face may be a back face of the body. The first type antenna 201 may be disposed on the upper left corner of the front surface of the body 10 and the lower right corner of the back surface of the body 10. Here, the arrangement position of the first type antenna 201 is not limited.

In one embodiment, the electronic device is a cell phone, and the first type antenna 201 is disposed on a second side of the cell phone, such that the distance between the target object and the first type antenna 201 is increased while avoiding the target object facing a screen for audio, video, and other activities; or reducing the SAR value of the first type antenna by using parts between the back surface and the front surface of the mobile phone.

Here, since the first type antenna 201 is diagonally disposed on the main body 10 of the electronic device, the first type antenna 201 is distributed on the diagonal, and the front and back sides and the four side surfaces of the electronic device can be detected. Therefore, when a target object approaches any one of the electronic devices, the sensor 30 connected to the first type antenna 201 can quickly detect the capacitance value between the first type antenna 201 and the target object. Therefore, the layout of the antenna is reasonable, and the detection risk surface for detecting whether a target object approaches is more comprehensive by the sensor 30. It is understood that the risk surface mentioned in the embodiments of the present disclosure indicates a risk space corresponding to each surface of the electronic device, and the detected risk surface is a risk space corresponding to the detected risk surface.

In some embodiments, the sensor 30 is a SAR sensor capable of acquiring a capacitance value between the first type antenna 201 and a target object; the capacitance value is indicative of a distance between the target object and the first type of object; a processor 40 is connected to the sensor 30 to determine the transmission power of the antenna assembly 20 based on the distance between the target object and the first type antenna 201.

In one embodiment, when the distance between the target object and the first type antenna 201 is less than a first predetermined distance value, the processor 40 determines that the transmission power of the antenna assembly 20 is less than a first predetermined power value; when the distance between the target object and the first type antenna 201 is greater than a second predetermined distance value, the processor 40 determines that the transmission power of the antenna assembly 20 is greater than a second predetermined power value; wherein the first predetermined power value and the second predetermined power value are determined based on a mapping relationship between predetermined power values and distance values.

In one embodiment, the processor 40 is capable of determining the transmission power of the antenna assembly 20 based on the capacitance value; wherein a magnitude of the transmission power is inversely related to a magnitude of the capacitance value.

In some embodiments, the processor 40 is capable of determining a transmit power of the antenna assembly 20 to transmit signals to the outside based on the capacitance value; alternatively, the processor 40 can determine the received power of the antenna assembly 20 for receiving the external signal based on the capacitance value. Specifically, the radio frequency current of the electronic device may be determined by determining the transmission power of the antenna assembly 20.

In some embodiments, the operating frequency band determined according to the structure of the first type of antenna 201 comprises a first predetermined frequency band; wherein the frequency value of the first predetermined frequency band indication is less than or equal to a first predetermined value.

In one embodiment, the structure of the first type antenna 201 comprises a length structure of the first type antenna 201.

In one embodiment, the structure of the first type antenna 201 includes a routing manner of the first type antenna 201; the routing mode can be an IFA mode, a Monopole mode, a Loop mode and a T mode.

In one embodiment, the length of the first type antenna 201 is one-half of the target operating wavelength of the first type antenna 201. In another embodiment, the length of the first type antenna 201 is an integer multiple of one quarter of the target operating wavelength. In this way, the length of the first type antenna 201 is adjusted, so that the radiation performance of the first type antenna 201 is strong.

In one embodiment, the frequency value of the first predetermined frequency band indication, determined on the basis of the structure of said first type of antenna 201, is inversely related to the target operating wavelength of said first type of antenna 201. For example, the frequency value of the first predetermined frequency band indication is less than or equal to a first predetermined value, which may be 960MHz. At this time, the first predetermined frequency band may be 700 to 960MHz.

In one embodiment, the first type antenna 201 having a length value greater than a predetermined value is set to accommodate a target wavelength of the first type antenna 201. Here, the detection range of the sensor 30 to which the first type antenna 201 is connected is positively correlated with the length of the first type antenna. Since the length of the first type antenna 201 is greater than the predetermined value, when the target object approaches the first type antenna 201, the sensor 30 connected to the first type antenna 201 can rapidly detect the capacitance between the first type antenna 201 and the target object. Thus, based on the length value of the first type antenna 201, the detection range in which the sensor 30 can detect whether a target object approaches is wide, and the detection accuracy is high. .

In one embodiment, the electronic device includes;

an antenna assembly 20, said antenna assembly 20 may be an assembly of multiple types of antennas; alternatively, the antenna assembly 20 may be an assembly of a predetermined number of antennas, which may be the same type of antenna.

In one embodiment, as shown in fig. 4, an antenna assembly 20, includes: a first type antenna 201 arranged on the opposite angle of the body 10 of the electronic device, a second type antenna 202 and a third type antenna 203 arranged in the predetermined range determined according to the first type antenna 201.

In one embodiment, a predetermined number of feed points and tuning points are provided at predetermined positions determined according to the positions of the first type antenna 201, the second type antenna 202 and the third type antenna 203.

In an embodiment of the present disclosure, the electronic device includes a body; an antenna assembly comprising a first type of antenna disposed on opposite corners of the body; a sensor connected to the first type antenna; the capacitance value between the antenna and a target object is obtained; a processor connected with the sensor; for determining a transmission power of the antenna assembly from the capacitance value. Here, since the first type antenna is disposed at a diagonal of the body, the first type antenna disposed within a limited spatial distance of the electronic device body has a larger radiation range. When a target object is close to the body of the electronic device, the range of the capacitance value between the target object and the first type antenna, which can be detected by the sensor, is larger, and the detected capacitance value is more accurate. Thus, a processor connected to the sensor can accurately determine the transmission power of the antenna assembly based on the accurate capacitance value detected by the sensor.

Compared with the method in the related art, the method can only detect the SAR value in a small range because the antenna is not reasonably arranged. In the embodiment of the disclosure, the first type antenna has reasonable spatial layout, a large sensing range of the sensor and high detection accuracy. The control of the transmission power of the antenna component is more accurate, the safety of protecting the target object is high,

in one embodiment, as shown in fig. 5, the electronic device further includes:

a capacitor 60 including a first terminal and a second terminal; the first end is grounded and the second end is connected to a feeding point determined according to the position of the first type antenna.

In one embodiment, the capacitor 60 is used to isolate the first type antenna from ground; the ground terminal may be a metal frame of the electronic device.

Here, since the capacitor 60 is not provided, the first type antenna 201 is directly grounded, which may cause a short circuit of the first type antenna 201, and thus the sensor 30 connected to the first type antenna may not detect a capacitance value between the target object and the first type antenna. Therefore, the capacitor 60 is arranged between the ground end and the feeding point determined according to the first type antenna 201, and is used for performing dc blocking processing on the first type antenna, so as to reduce the possibility that the dc affects the signal transceiving quality of the antenna in the radio frequency state; the radio frequency state is a state that the antenna transmits high-frequency alternating current.

In one embodiment, the capacitance of the capacitor 60 is sized based on a target blocking value of the first type antenna 201; if the target blocking value is larger than a first preset value, the capacity of the capacitor is larger than the preset value; and if the target blocking value is smaller than a first preset value, the capacity of the capacitor is smaller than the preset value. The target dc blocking value is used to indicate a target requirement for dc current isolation for the first type antenna 201.

In one embodiment, the capacitance is 33pF.

In one embodiment, a feeding point and a tuning point are provided at predetermined positions determined according to the first type antenna 201.

In one embodiment, one end of the capacitor is grounded, and the other end of the capacitor is connected with the feeding point; and/or one end of the capacitor is grounded, and the other end of the capacitor is connected with the tuning point. In this way, the first type antenna 201 is prevented from being directly grounded, so as to reduce the possibility that direct current exists to affect the signal transceiving quality of the antenna in a radio frequency state.

In one embodiment, the number of capacitances is determined based on the number of feed points and tuning points.

Illustratively, as shown in fig. 6, the first-type antenna 201 is disposed at the upper right corner of the electronic device body 10; at least one capacitor is connected to the feed point 501 and the tuning point 701, respectively.

In one embodiment, one end of the capacitor is grounded, and the other end of the capacitor is connected with a connection point 801; wherein the connection point 801 is a connection point between the sensor 30 and the first type antenna 201. Specifically, the sensor 30 may be of the SX9325 type.

In another embodiment, as shown in fig. 7, the first type antenna 201 is arranged in the lower left corner of the electronic device. Setting a tuning point 702 at a predetermined position determined according to the first type antenna 201; capacitors 60 are respectively arranged at the tuning point 702 and the connection point 802; wherein the connection point 802 indicates a connection point of a sensor 30 with the first type antenna 201. Specifically, the sensor 30 may be of the SX9325 model.

In one embodiment, the antenna assembly 20 further includes: a second type of antenna 202.

In one embodiment, the distance between the second type of antenna 202 and the first type of antenna is less than a predetermined threshold; wherein the working frequency band determined by the structure of the second type antenna 202 includes a second predetermined frequency band; the frequency value indicated by the second predetermined frequency band range is larger than the frequency value indicated by the first predetermined frequency band.

In some embodiments, the distance between the second type of antenna 202 and the first type of antenna is less than a predetermined threshold, including: the distance between said second type antenna 202 and said first type antenna 201 reference point is less than a predetermined threshold; wherein the reference point may be a center point or an end point on the first type antenna 201, and the predetermined threshold is determined based on a sensing range of the sensor 30.

Illustratively, the distance between the second type antenna 202 and the reference point of the first type antenna 201 is less than a predetermined threshold, wherein the position indicated within the predetermined threshold is within the sensing range of the sensor 30; the sensing range of the sensor 30 indicates that the sensor 30 is within the sensing range and can detect a capacitance value between the first type antenna 201 and a target object.

Here, since the distance between the second type antenna 202 and the first type antenna 201 is smaller than a predetermined threshold value, which is determined based on the sensing range of the sensor 30, if a capacitance value is generated between the target object and the second type antenna 202 within the sensing range, a capacitance value is also generated between the target object and the first type antenna 201. The sensor 30 connected to the first type antenna 201 only needs to detect whether a target object is approaching the first type antenna 201, and can detect whether a target object is approaching the second type antenna 202. In this way, the second type antenna 202 is arranged in the predetermined range determined by the first type antenna 201, so that the capacitance value between the first type antenna 201 and the target object detected by the sensor 30 can indicate the distance between the target object and the second type antenna 202, and the detection efficiency is high.

In one embodiment, the structure of the second type of antenna 202 comprises a length structure of the second type of antenna 202.

In one embodiment, the length of the second type antenna 202 is one-half of the target operating wavelength of the second type antenna 202. In another embodiment, the length of the second type antenna 202 is an integer multiple of one quarter of the target operating wavelength.

In one embodiment, the frequency value of the indication of the second predetermined frequency band determined by the structure of the second type of antenna 202 is inversely related to the target operating wavelength of the second type of antenna 202. For example, the frequency value of the second predetermined frequency band indication is larger than the frequency value of the first predetermined frequency band indication, and the first predetermined frequency band is 700 to 960MHz. At this time, the second predetermined frequency band may be 1710 to 2690MHz.

In one embodiment, based on the structure of the second type antenna, communication can be performed in the co-frequency bands of B1, B3, B40, B41 and NR.

In one embodiment, as shown in fig. 6, a gap 90 is disposed between the first type antenna 201 and the second type antenna 202, and the gap 90 is used for preventing the transmission and reception signals between the first type antenna 201 and the second type antenna 202 from interfering. For example, the gap may be a break. In this way, the first type antenna 201 is spatially separated from the second type antenna 202.

In one embodiment, the width of the gap is determined by an interference rejection target value between the first type of antenna and the second type of antenna, and if the interference rejection target value is greater than a first predetermined value, the width of the gap is greater than a first predetermined width value; and if the anti-interference target value is smaller than a second preset value, the width of the gap is smaller than a second preset width value.

In one embodiment, the antenna assembly 20 further includes: a third type of antenna 203.

In one embodiment, the distance between the third type of antenna 203 and the first type of antenna is less than a predetermined threshold; wherein the working frequency band determined by the structure of the third type antenna 203 comprises a third predetermined frequency band; the frequency value of the third predetermined frequency band indication is greater than the frequency value of the second predetermined frequency band indication.

In an embodiment, the structure of said third type of antenna 203 comprises a length structure of said third type of antenna 203.

In one embodiment, the length of third type antenna 203 is one-half of the target operating wavelength of third type antenna 203. In another embodiment, the length of the third type of antenna 203 is an integer multiple of a quarter of the target operating wavelength.

In one embodiment, the frequency value of the indication of the third predetermined frequency band, determined on the basis of the structure of said third type of antenna 203, is inversely related to the target operating wavelength of said third type of antenna 203. For example, the frequency value indicated by the third predetermined frequency band is greater than the frequency value indicated by the second predetermined frequency band, which is 1710 to 2690MHz. At this time, the third predetermined frequency band may be 3300 to 4200MHz.

In one embodiment, the electronic device further includes:

an LDS accessory, a distance between the LDS accessory and the first type antenna is less than a predetermined threshold; wherein the third type antenna 203 is disposed on the LDS accessory.

In one embodiment, the LDS enclosure is disposed on a surface of the electronic device, and the third type antenna 203 is laser-induced to mold on the LDS enclosure. The LDS accessory facilitates reducing interference of metal inside the electronic device with the third type antenna 203, reducing the volume of the electronic device.

In one embodiment, the predetermined threshold is less than 5mm.

In one embodiment, third type antenna 203 is disposed on the LDS enclosure. As such, the LDS accessory is disposed within a predetermined range determined by the first type antenna 201, and the third type antenna 203 is disposed on the LDS accessory, so that the capacitance value between the first type antenna 201 and the target object detected by the sensor 30 can indicate the distance between the target object and the third type antenna 203, and the detection efficiency is high.
