[0035] In addition, when describing representative embodiments, the specification may have presented the method and / or process as a particular sequence of steps. However, to the extent that the method or process does not depend on a particular order of the steps described herein, the method or process should not be limited to the particular order of steps described.

[0036] Currently, the main metal frame antenna switching method is to switch the transmitting antenna to the top antenna when the bottom antenna is held by hand to avoid being held. However, this switching method is too single, and there is still a risk that the antenna is held by hand in different usage scenarios, such as in the landscape game mode.
[0037] For this reason, the embodiments of the present disclosure provide an electronic device, such as Figure 1 shown, including:
[0038] A metal frame, the metal frame includes a plurality of frame segments, wherein at least one frame segment serves as a first main antenna body 11, and at least one frame segment serves as a second main antenna body 12, and the first main antenna body 11 and the second main antenna body 12 are not adjacent;
[0039] A first auxiliary antenna body 21, disposed within the electronic device;
[0040] A detection module 30, configured to detect the occlusion state of a frame segment at a preset position;
[0041] A control module 40, connected to the detection module 30, is configured to, according to the detection result of the detection module 30, when it is determined that the first main antenna body or the second main antenna body is in an occluded state or may be in an occluded state, control the first switching circuit 51 to switch the transceiver link of the first main antenna body or the second main antenna body that is in or may be in the occluded state to the first auxiliary antenna body 21, and the first auxiliary antenna body 21 replaces the occluded or possibly occluded first main antenna body or second main antenna body to perform signal transceiver;
[0042] The first switching circuit 51 is respectively connected to the control module 40, the first main antenna body 11, the second main antenna body 12, and the first auxiliary antenna body 21. According to the control of the control module 40, the transceiver link of the first main antenna body 11 is switched to the first auxiliary antenna body 21, or the transceiver link of the second main antenna body 12 is switched to the first auxiliary antenna body 21.
[0043] In the electronic device according to the embodiment of the present disclosure, by arranging an auxiliary antenna body in the non-metal frame area, in the case of being affected by occlusion (such as being held by hand, etc.), the metal frame antenna can be switched to the auxiliary antenna body, and the single switching method of switching between the original metal frame antennas is extended to the switching between the metal frame antenna and the auxiliary antenna body (non-frame antenna) located inside the electronic device, ensuring that at least two antennas work simultaneously to achieve multiple input multiple output (MIMO).
[0044] In an exemplary embodiment, as Figure 2 shown, in the metal frame of the electronic device, at least one frame segment serves as a third main antenna body 13, and at least one frame segment serves as a fourth main antenna body 14. The third main antenna body 13 and the fourth main antenna body 14 are not adjacent. The electronic device further includes a second auxiliary antenna body 22 located inside the electronic device, and a second switching circuit 52; wherein:
[0045] A control module 40, connected to the detection module 30, is used to, according to the detection result of the detection module 30, when it is determined that the third main antenna body 13 or the fourth main antenna body 14 is in an occluded state or may be in an occluded state, control the second switching circuit 52 to switch the transceiver link of the main antenna body that is in or may be in the occluded state to the second auxiliary antenna body 22;
[0046] The second switching circuit 52 is respectively connected to the control module 40, the third main antenna body 13, the fourth main antenna body 14, and the second auxiliary antenna body 22. According to the control of the control module 40, the transceiver link of the third main antenna body 13 is switched to the second auxiliary antenna body 22, or the transceiver link of the fourth main antenna body 14 is switched to the second auxiliary antenna body 22.
[0047] Optionally, the detection module for detecting the occlusion state of the preset position border segment may include a Specific Absorption Rate (SAR) sensor for sensing the hand-held state. The Specific Absorption Rate (SAR) is an internationally common indicator for evaluating the impact of radio waves on the human body. It belongs to the safety standard indicator and is strictly regulated by regulatory agencies in various countries (regions) around the world. Currently, the two internationally common standards are 1.6 W / Kg of the Federal Communications Commission (FCC) in the United States and 2.0 W / Kg of the European Union. For electromagnetic wave signals of different frequencies, the requirements of SAR regulatory agencies in each region are slightly different. Taking the FCC as an example, for radio frequency signals below 3 GHz, the average SAR value within a time period of 100 seconds is required not to exceed the upper limit requirement of 1.6 W / Kg. Therefore, the real-time SAR value can exceed 1.6 W / Kg, as long as the average value within the time window required by the regulations (such as 100 ms of the FCC) is controlled within the range required by the regulations. SAR is directly proportional to the radio frequency transmission power. The higher the power, the higher the SAR value. The SAR sensor can be set on the metal border for detecting the SAR value of the electronic device. When the SAR value exceeds the preset value, the electronic device is controlled to reduce the transmission power. The inventor of the present application found that when the human body approaches the metal border segment where the SAR sensor is located, the SAR value detected by the SAR sensor will change. Therefore, in this embodiment, the SAR sensor is reused as the detection module for detecting the occlusion state of the metal border segment, and whether the metal border segment is occluded is detected through the SAR sensor.
[0048] Due to the limited space of the electronic device, it may not be possible to set a detection module that can directly detect the occlusion state on all metal frame antennas. Therefore, this embodiment also provides a solution that can combine other parameters to determine whether the main antenna body may be in an occluded state. For example, the occlusion state of the metal frame antenna can be determined by combining the holding direction. In this exemplary solution, the detection module can also be used to detect the holding direction of the electronic device, that is, the detection module further includes a sensor for detecting the holding direction of the electronic device, such as a gyroscope. Through this sensor, it can be determined whether the holding direction of the electronic device is vertical or horizontal. The vertical holding means the way of holding the electronic device when it is in a portrait display state, and the horizontal holding means the way of holding the electronic device when it is in a landscape display state. For example, for two adjacent metal frame antennas, a sensor for detecting the occlusion state is provided on the first metal frame antenna, and a sensor for detecting the occlusion state is not provided on the second metal frame antenna. However, when the electronic device is in a certain holding state, such as the vertical holding state, when the first metal frame antenna is occluded, the second metal frame antenna will also be occluded with a high probability. Then, when it is detected that the first metal frame antenna is in an occluded state and the holding direction of the current electronic device is the preset holding direction, it can be determined that the second metal frame antenna may be in an occluded state, and the transceiver link of the second metal frame antenna can be switched to its auxiliary antenna body.
[0049] Figure 1 The first main antenna body 11 and the second main antenna body 12 in the embodiment are a set of main antenna bodies (which can be called the first main antenna unit) for transmitting and receiving one path of signals. Figure 2 The third main antenna body 13 and the fourth main antenna body 14 in the embodiment are another set of main antenna bodies (which can be called the second main antenna unit) for transmitting and receiving another path of signals. For example, the first main antenna unit can be used to transmit and receive 4G and / or 5G signals, and the second main antenna unit can be used to transmit and receive WIFI signals.
[0050] The auxiliary antenna body in this embodiment can be arranged inside the electronic device, for example, on the inner side of the back cover.
[0051] Specifically:
[0052] The first auxiliary antenna body 21 can be a flexible printed circuit (FPC) antenna radiator, or a laser direct structuring (LDS) antenna radiator, or a print direct structuring (PDS) antenna radiator.
[0053] The second auxiliary antenna body 22 may be an FPC antenna radiator, an LDS antenna radiator, or a PDS antenna radiator.
[0054] In an exemplary embodiment, the electronic device may be a terminal with only one opening / closing state, or may also be a terminal including at least two opening / closing states. For example, the electronic device may include an unfolded state and a retracted state. The unfolded state refers to a state where the screen on the electronic device is fully unfolded, and the retracted state refers to a state where the screen on the electronic device is partially retracted or fully retracted. The screen on the electronic device may be, for example, a foldable screen or a scroll screen (or a rollable screen).
[0055] Since the antenna environment at the top and bottom may change due to the unfolding of the screen, in order to ensure the best antenna performance, the detection module may also be used to detect the opening / closing state of the electronic device, that is, the detection module may further include a sensor for detecting the opening / closing state of the electronic device, such as a Hall device. The control module is connected to the detection module and is used to adjust the resonant state of the main antenna body according to the opening / closing state of the electronic device detected by the detection module. Optionally, the resonant state of the main antenna body may be adjusted by adjusting the resonant state of the antenna tuning switch. For example, when the electronic device is in the unfolded state, the antenna resonant state is adjusted to the first resonant state that makes the current antenna reception effect optimal, and when the electronic device is in the retracted state, the antenna resonant state is adjusted to the second resonant state that makes the current antenna reception effect optimal.
[0056] The electronic device may include a mobile phone, a tablet computer, a handheld computer, a mobile Internet device (MID), a wearable device, and various forms of user equipment (UE), mobile station (MS), terminal device, etc.
[0057] In an exemplary embodiment, as shown in FIG. 3, the electronic device may include a main body. The main body is rectangular and includes a top edge 121, a first side edge 122, a bottom edge 123, and a second side edge 124 that are connected in sequence end to end. The top edge 121 and the bottom edge 123 are opposite and spaced apart. The first side edge 122 and the second side edge 124 are opposite and spaced apart. The first side edge 122 is connected to the top edge 121 and the bottom edge 123 respectively. The second side edge 124 is connected to the top edge 121 and the bottom edge 123 respectively. The lengths of the top edge 121 and the bottom edge 123 are the same, and the lengths of the first side edge 122 and the second side edge 124 are the same. The length of the top edge 121 (or the bottom edge 123) is less than the length of the side edge (122 or 124). Each side edge may be made of a metal material to form a metal frame. By providing a plurality of gaps, the metal frame is divided into a plurality of frame segments, and one of the frame segments is used as the main antenna.
[0058] Taking a scrollable mobile terminal as an example for illustration, this mobile terminal (hereinafter referred to as the terminal) can adopt a scrollable screen. Figure 3 is a schematic diagram of a scrollable mobile terminal. Figure 3a It is a top view of the front of the mobile terminal when the scrollable screen is retracted. When the scrollable screen is retracted, that is, when the scrollable mobile terminal is in the retracted state, the main body of the mobile terminal is rectangular, including a top edge 121, a first side edge 122, a bottom edge 123, and a second side edge 124 that are connected end to end in sequence. The top edge 121 and the bottom edge 123 are opposite and spaced apart, the first side edge 122 and the second side edge 124 are opposite and spaced apart. The lengths of the top edge 121 and the bottom edge 123 are the same, the lengths of the first side edge 122 and the second side edge 124 are the same, and the length of the top edge 121 (or the bottom edge 123) is less than the length of the side edge (122 or 124). For example, the screen size (i.e., the size of the screen diagonal) is 6.8 inches. Each side can be made of a metal material. Figure 3b It is a top view of the front of the mobile terminal when the scrollable screen is unfolded. After unfolding, the length of the top edge 121 is greater than the length of the top edge 121 in the retracted state, and the lengths of the first side edge 122 and the second side edge 124 remain unchanged. For example, the screen size unfolds to 7.4 inches. Figure 3c It is a top view of the back of the mobile terminal after the scrollable screen is retracted. Through the scrollable screen design, the user's experience demand for large-screen operation can be realized. The above dimensions are only examples, and the present disclosure does not limit this.
[0059] By installing a driving motor and a pulley bearing structure inside the fuselage, where the driving motor can output a constant force for the retraction and extension of the screen, and the pulley bearing structure enables the screen to move along the central axis of the mobile terminal (the central axis extending along the direction of the top edge or the bottom edge). On the one hand, it can ensure that the flexible screen does not produce creases after bending, and on the other hand, it can ensure the smoothness of the screen during the curling process. Due to the space requirement of the pulley bearing structure, the available space for the antenna will be in the top, bottom, and left regions of the mobile phone. Figure 4a It is a schematic layout diagram of the internal antenna and the pulley bearing structure of the mobile terminal. In this example, the antenna is arranged on the top edge 121, the bottom edge 123, and the second side edge 124, while the pulley bearing mechanism is arranged inside the first side edge 122. When the scrollable terminal is in the retracted (or closed) state, the scrollable screen will be retracted inside the terminal, as Figure 4b shown. When the scrollable terminal is in the slid-open (or unfolded) state, due to the unfolding of the screen, there will be an unfolded area 60 without components inside the back of the terminal, as Figure 4c shown. Inside this unfolded area 60, it can be used for the layout of the auxiliary antenna body. The implementation of the antenna in this unfolded area can select the LDS technology, the FPC process, or the PDS process to prepare the antenna according to the available structural space. This antenna can be prepared on the inner side of the back cover of the terminal mobile phone, as shown in Figure 5. Figure 5aTop view and side view of the terminal when in the retracted state, Figure 5b Top view and side view of the back of the terminal when in the slid-open state, Figure 5c Schematic diagram of the position of the back cover antenna when in the retracted state, Figure 5d Schematic diagram of the position of the back cover antenna when in the slid-open state.
[0060] When the sliding-roll type terminal is in the slid-open state, there are several possible user usage scenarios, as shown in Figure 6, where Figure 6a is the scenario simulation diagram of the user holding the terminal vertically (vertical holding scenario), and at this time the antenna area is at the position indicated by the arrow in the figure; Figure 6b is a scenario simulation diagram of the user holding the terminal horizontally (horizontal holding scenario 1); Figure 6c is another scenario simulation diagram of the user holding the terminal horizontally (horizontal holding scenario 2). As shown in the figure, in the vertical holding scenario, the right thumb may block the antenna, and in the horizontal holding scenario 1, the antenna area is not affected by the hand grip. In the horizontal holding scenario 2, both thumbs may also block the antenna. However, it will not affect the auxiliary antenna body provided on the inner side of the back cover. Therefore, when it is determined that the metal frame antenna is blocked or may be blocked, the signal link on the main antenna can be switched to the auxiliary antenna body to ensure the user communication experience.
[0061] Figure 7 Is a schematic diagram of a sliding-roll type terminal, Figure 7 The shown terminal includes a metal frame, and a plurality of gaps are provided on the metal frame, dividing the metal frame into a plurality of metal frame segments. Among them, metal frame segment 11 is the first main antenna body, metal frame segment 12 is the second main antenna body, metal frame segment 13 is the third main antenna body, metal frame segment 14 is the fourth main antenna body, and the LDS antenna (or FPC antenna or PDS antenna) located inside the back cover is the first auxiliary antenna body 21, and the LDS antenna (or FPC antenna or PDS antenna) located inside the back cover is the second auxiliary antenna body 22. At positions where the user may hold the terminal, for example, on metal frame segment 11, metal frame segment 13, and metal frame segment 12, SAR sensor pins (Pad in the figure) are provided to detect whether there is occlusion (such as a human body approaching), and the detection module is not shown in the figure.
[0062] In this embodiment, the operating frequency band of the first main antenna body 11 is, for example, L+MHB DRX (Diversity Receive) of LTE and / or 5G NR, the operating frequency band of the second main antenna body 12 is, for example, L+MHB PRX (Primary Receive) of LTE and / or 5G NR, the operating frequency band of the third main antenna body 13 is, for example, GPS+WiFi 2.4+5GHz, and the operating frequency band of the fourth main antenna body 14 is, for example, WiFi 2.4+5GHz. The operating frequency band of the first auxiliary antenna body 21 is, for example, L+MHB of LTE and / or 5G NR, and the operating frequency band of the second auxiliary antenna body 22 is, for example, WiFi 2.4+5GHz.
[0063] 5G (the 5th Generation) is the fifth-generation mobile communication technology. N represents new radio (NR), that is, 5G new radio, and NG represents next generation (NG), that is, 5G core network. L represents low frequency, and MHB represents medium and high frequency.
[0064] The supported frequency bands of the antenna in this embodiment are not limited to WiFi or L+MHB of LTE / 5G NR, and can also be one or more of the following antenna designs: LB (low frequency), MB (medium frequency), HB (high frequency), UHB (ultra-high frequency) band, and any frequency band of GPS.
[0065] The first switching circuit 51 is used to switch the first main antenna body 11 to the first auxiliary antenna body 21, or switch the second main antenna body 12 to the first auxiliary antenna body 21, and switch the first auxiliary antenna body 21 back to the first main antenna body 11, or switch the first auxiliary antenna body 21 back to the second main antenna body 12. The first transceiver circuit is connected to the first switching circuit 51 and is, in this example, a transceiver circuit for LTE / 5G NR, responsible for transmitting and receiving LTE and / or 5G NR radio frequency signals.
[0066] The second switching circuit 52 is used to switch the third main antenna body 13 to the second auxiliary antenna body 22, or switch the fourth main antenna body 14 to the second auxiliary antenna body 22, and switch the second auxiliary antenna body 22 back to the third main antenna body 13, or switch the second auxiliary antenna body 22 back to the fourth main antenna body 14. The second transceiver circuit is connected to the second switching circuit 52 and is, in this example, a WiFi transceiver circuit, responsible for transmitting and receiving WiFi radio frequency signals.
[0067] The first antenna resonance switch 61 is used to switch the operating frequency band of the first main antenna body 11, and the second antenna resonance switch 62 is used to switch the operating frequency band of the second main antenna body 12. The antenna resonance switch device is a switch used for antenna design, including SPxT (single-pole x-throw, x is a positive integer greater than 1), xSPST (x single-pole single-throw) or variable capacitors, etc.
[0068] In this embodiment, the detection module includes a gyroscope (G-Sensor), a Hall device (Hall Sensor) and a SAR sensor (SAR Sensor). The gyroscope is a device based on the theory of conservation of angular momentum for sensing and maintaining direction. The Hall device is a semiconductor electromagnetic device that uses the Hall effect to work. The SAR sensor can be a capacitive sensor, which may include a conductive sheet and a capacitive sensing controller.
[0069] The controller determines whether the Hall device detects that the terminal is in the unfolded state. If so, the antenna resonance state can be changed by adjusting the first antenna resonance switch 61 (or the second antenna resonance switch 62 as required) to achieve the best antenna performance. If not, the antenna resonance state can be changed by adjusting the second antenna resonance switch 62 (or the first antenna resonance switch 61 as required) to achieve the best antenna performance.
[0070] The controller determines whether the gyroscope detects that the terminal is held horizontally. If it is determined to be held horizontally, it further determines whether the SAR sensor at the first main antenna body 11 senses occlusion (i.e., whether the user is holding it with a hand). If occlusion is sensed, the transceiver link of the first main antenna body 11 is switched to the first auxiliary antenna body 21. If no occlusion is sensed, it is not switched. If it is determined to be held horizontally, it can also further determine whether the SAR sensor at the third main antenna body 13 senses occlusion. If occlusion is sensed, the transceiver link of the third main antenna body 13 is switched to the second auxiliary antenna body 22. If it is not held horizontally, it further determines whether the SAR sensor at the second main antenna body 12 senses occlusion. If occlusion is sensed, at this time, the right thumb is likely to cover the fourth main antenna body 14, that is, the fourth main antenna body 14 may be occluded, and the transceiver link of the fourth main antenna body 14 is switched to the second auxiliary antenna body 22.
