[0027] Here, exemplary embodiments will be described in detail, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are only examples of devices and methods consistent with some aspects of the present disclosure as detailed in the attached claims. With the development of information technology, while the public enjoys the various conveniences brought by wireless communication devices, they are also increasingly concerned about the impact of electromagnetic radiation from wireless communication terminals on human health. In the field of antenna research and development and testing, antenna engineers pay attention to another indicator in addition to TRP (total radiated power), TIS (total isotropic sensitivity), RL (Return loss), and Efficiency, they also pay great attention to another indicator-SAR (Specific Absorption Rate). The size of SAR indicates the size of the impact of electromagnetic radiation from electronic equipment on human health. In the design of antennas, the main focus is on the impact of electromagnetic radiation from wireless communication terminals on human heads. The SAR value is closely related to the radiation power of the electronic device. Usually, the SAR value is proportional to TRP. In the design, TRP and SAR are a pair of contradictions. Therefore, in the design, the relationship between the two needs to be well balanced.
[0028] In order to overcome the problems existing in the related art, the present disclosure provides a middle frame assembly and an electronic device.
[0029] According to a first aspect of an embodiment of the present disclosure, a middle frame assembly is provided, comprising: an antenna, comprising an antenna radiator; a SAR sensor, comprising a control unit and a transmission line, the transmission line being electrically connected to the antenna radiator through at least one upper frame point so as to sense through at least a portion of the antenna radiator and transmit the sensed information to the control unit; and at least a portion of the transmission line is arranged parallel to the antenna radiator, and in the parallel-arranged portion, the distance between the transmission line and the antenna radiator is less than a set threshold.
[0030] In the present disclosure, the transmission line of the SAR sensor is electrically connected to the antenna radiator through at least one upper frame point, so that the antenna radiator is used as the sensing end of the SAR sensor. The sensing range of the SAR sensor can be increased, and the accuracy of the SAR value can be improved. In the present disclosure, at least part of the transmission line is arranged parallel to the antenna radiator, and the transmission line is arranged along the antenna radiator, so that the environmental changes of the antenna radiator can be actually detected, so that a more accurate SAR value can be obtained. In the part of the transmission line that is arranged parallel to the antenna radiator, the distance between the transmission line and the antenna radiator is less than a set threshold. Within the set threshold, the transmission line can both actually detect the environmental changes of the antenna radiator and avoid affecting the radiation efficiency of the antenna radiator.
[0031] Figure 1 The figure is a schematic structural diagram of a middle frame assembly according to an exemplary embodiment. Figure 2 It is a schematic diagram of a partial structure of a middle frame assembly according to an exemplary embodiment. Figure 3 is a schematic diagram of a partial structure of a middle frame assembly according to another exemplary embodiment.
[0032] like Figure 1 As shown, in the present disclosure, the middle frame assembly 10 may include an antenna, an antenna radiator, a middle frame 200, and a SAR sensor. The SAR sensor may include a control unit 303 and a transmission line 304 electrically connected to each other. The transmission line 304 may be electrically connected to the antenna radiator, sense through at least a portion of the antenna radiator, and transmit the sensed information to the control unit 303.
[0033] In an exemplary embodiment of the present disclosure, the middle frame 200 assembly includes a frame 100 . The frame 100 may be disposed on a peripheral side of the middle frame 200 , and at least a portion of the frame 100 may be an antenna radiator.
[0034] In the present disclosure, the antenna may be any antenna, and the first antenna ANT1 is taken as an example for explanation below.
[0035] In the present disclosure, sensing is performed through at least a portion of the antenna radiator, thereby increasing the sensing range of the sensing end of the SAR sensor. In addition, one component has two functions, which helps to achieve a thinner and lighter middle frame assembly 10.
[0036] In an exemplary embodiment of the present disclosure, the SAR sensor may be a capacitive SAR sensor (SAR sensor), and the antenna radiator may serve as a sensing end to sense the electromagnetic wave absorption ratio and send the electromagnetic wave absorption ratio signal to the control unit 303 .
[0037] SAR (Specific Absorption Rate) is the electromagnetic wave energy absorption ratio of mobile phones and other terminals or wireless products.
[0038] Under the influence of external electromagnetic fields, an induced electromagnetic field will be generated in the human body. Since various organs of the human body are lossy media, the electromagnetic field in the body will generate currents, resulting in the absorption and dissipation of electromagnetic energy. SAR is often used in biological dosimetry to characterize this physical process. The meaning of SAR is the electromagnetic power absorbed or consumed by a unit mass of human tissue.
[0039] The SAR value generally refers to the heat energy generated by electromagnetic waves in mobile phone products, which is a measure of the impact on the human body. In the present disclosure, the antenna radiator can be used as a sensing end to sense the electromagnetic wave absorption ratio, and the principle of electromagnetic energy dissipation by human tissue can be used to accurately determine whether the corresponding antenna area is blocked by an object.
[0040] Since the electromagnetic waves of the communication antenna have a certain impact on the human body, for example, the SAR value indicates how much the heat energy of the mobile phone will affect the human body. The larger the value, the greater the impact on the human body, and vice versa. The detection data of the capacitance detection end can also be used to control the terminal's electromagnetic waves within a certain range when there is an object blocking it, so as to minimize the impact on the human body.
[0041] The United States and Europe have already set regulations on the SAR (Specific Absorption Rate) of mobile phone radiation to the human body. The US standard is 1.6W / kg (1 gram) and the European standard is 2.0W / kg (10 grams). The safety standard value for mobile phones announced by the Federal Communications Commission (FCC) of the United States is 1.6, so as long as the SAR value of a mobile phone is below 1.6, it is a product within the safety standard.
[0042] In the present disclosure, at least a portion of the transmission line 304 may be arranged in parallel with the antenna radiator, that is, the transmission line 304 may be arranged in parallel with the antenna radiator. The transmission line 304 is arranged along the antenna radiator, and the environmental changes of the antenna radiator can be actually detected, so that a more accurate SAR value can be obtained. In some embodiments, the transmission line 304 may also be arranged in parallel with the antenna radiator as a whole.
[0043] In the present disclosure, in the portion of the transmission line 304 that is arranged parallel to the antenna radiator, the distance between the transmission line 304 and the antenna radiator may be less than a set threshold. Regarding setting the threshold, it may be set differently according to different antenna situations. For example, in some embodiments, it may be determined according to the range of the antenna clearance. For example, it may be determined according to the distance between the transmission line 304 and the antenna radiator being set so as not to affect the antenna clearance.
[0044] In the exemplary embodiment of the present disclosure, Figures 1 to 3 As shown, the frame 100 may include a first frame 101 and a second frame 102 extending in different directions. Specifically, the antenna radiator may include a first side extending on the first frame 101 and a second side extending on the second frame 102.
[0045] like Figures 1 to 3As shown, the first section 341 of the transmission line 304 can be arranged parallel to the first frame 101, and the distance between the first section 341 and the first frame 101 can be 0.5 mm-1.2 mm, for example, about 0.8 mm.
[0046] like Figures 1 to 3 As shown, the second section 342 of the transmission line 304 can be arranged parallel to the second side, and the distance between the second section 342 and the second side can be 0.2 mm-0.5 mm. For example, it can be about 0.24 mm.
[0047] In the present disclosure, the transmission line 304 and the antenna radiator are as close to the antenna radiator as possible while satisfying the antenna clearance condition, that is, the transmission line 304 is not arranged under the antenna clearance, so as not to cause interference to the radiation space of the antenna.
[0048] For example, in some embodiments, the distance between the transmission line 304 and the antenna radiator may be greater than or equal to the antenna clearance of the antenna.
[0049] Figure 4 The diagram is a schematic structural diagram of an electronic device according to an exemplary embodiment. Figure 4 The schematic diagram of the structure of the electronic device 40 is shown. The electronic device 40 may include a middle frame 200 , a frame 100 and a display screen 30 .
[0050] In an exemplary embodiment of the present disclosure, the antenna clearance at the top of the middle frame assembly 10 may be 0.5 mm to 1.2 mm. Figure 4 As shown, the antenna clearance L3 at the top of the electronic device 40 can be about 0.8 mm. In the present disclosure, the top of the middle frame assembly 10 is the top of the electronic device. Taking a mobile phone as an example, the top of the middle frame assembly 10 can be the part close to the user's ear when answering a call. For example, Figure 1 In the middle, it can be part of the first frame 101.
[0051] Figure 5 The diagram is a schematic structural diagram of an electronic device according to an exemplary embodiment. Figure 5 The schematic diagram of the structure of the electronic device 40 is shown. The electronic device 40 may include a middle frame 200 , a frame 100 and a display screen 30 .
[0052] In the exemplary embodiment of the present disclosure, the antenna clearance at the bottom of the middle frame assembly 10 is 0.8 mm to 1.5 mm. Figure 5 As shown, the antenna clearance L2 at the top of the electronic device 40 can be about 1.0 mm. In the present disclosure, the top of the middle frame assembly 10 is the bottom of the electronic device. Taking a mobile phone as an example, the top of the middle frame assembly 10 can be a part opposite to the top. For example, in Figure 1In the example, the fifth side 105 may be part of the fifth side 105 .
[0053] Figure 6 The diagram is a schematic structural diagram of an electronic device according to an exemplary embodiment. Figure 6 The schematic diagram of the structure of the electronic device 40 is shown. The electronic device 40 may include a middle frame 200 , a frame 100 and a display screen 30 .
[0054] In an exemplary embodiment of the present disclosure, the antenna clearance at the side of the middle frame assembly 10 between the top and the bottom is 0.2 mm to 0.5 mm. Figure 6 As shown, the antenna clearance L1 at the top of the electronic device 40 may be approximately 0.24 mm.
[0055] In an exemplary embodiment of the present disclosure, the distance between the transmission line and the antenna radiator may be 0.5 mm to 1.5 mm, for example, any one of 0.8 mm, 1.0 mm, 1.2 mm, and 1.3 mm.
[0056] In the exemplary embodiment of the present disclosure, Figure 1 As shown, the transmission line 304 may be electrically connected to the first side via the first upper frame point 311. In such an embodiment, the entire antenna radiator may serve as the sensing end of the SAR sensor, or a portion of the antenna radiator may serve as the sensing end of the SAR sensor.
[0057] like Figure 1 As shown, the first upper frame point 311 may be disposed at a position close to the first end of the antenna radiator, and the first end of the antenna radiator may be an end portion of the antenna radiator at the first side.
[0058] The antenna radiator also has a second end opposite to the first end, and the transmission line 304 can be routed along a path parallel to the antenna radiator near the second end of the antenna radiator to the first upper frame point 311. The second end can be the end of the antenna radiator on the second side.
[0059] like Figure 1 As shown, the transmission line 304 is routed from the position connected to the control unit 303 toward the antenna radiator, and then continues to be routed in a direction parallel to the second side of the antenna radiator (i.e., the second section 342). When the second section 342 is routed to a position close to the first side, the transmission line 304 changes direction and continues to be routed in a direction parallel to the first side to the first upper frame point 311 (i.e., the second section 342).
[0060] In the exemplary embodiment of the present disclosure, Figure 1As shown, the transmission line 304 can be electrically connected to the second side through the second upper frame point 312. In such an embodiment, the entire antenna radiator can be used as the sensing end of the SAR sensor, or a portion of the antenna radiator can be used as the sensing end of the SAR sensor. For example, the portion of the second side of the antenna radiator from the second upper frame point 312 toward the fifth side 105 can be used as the sensing end of the SAR sensor.
[0061] In some embodiments, the transmission line 304 may also be electrically connected to the antenna radiator through the first upper frame point 311 and the second upper frame point 312. A switch may be provided on the connection circuit between the first upper frame point 311 and the second upper frame point 312 and the antenna radiator, and the SAR sensor may be switched through which upper frame point to be framed by controlling the switch to be turned on or off.
[0062] In the present disclosure, the position of the upper frame point is different, the direction of the current flow is different, and thus the range of the antenna radiator as the sensing end is also different. In manufacturing, the upper frame point can be determined according to the requirements of the antenna setting of the electronic device.
[0063] In the exemplary embodiment of the present disclosure, Figure 1 As shown, the transmission line 304 can be arranged in parallel with the antenna radiator. The parallel arrangement described in the present disclosure refers to a substantially parallel arrangement, that is, most of the transmission line 304 is parallel to the adjacent antenna radiator.
[0064] In the present disclosure, in an exemplary embodiment of the present disclosure, the middle frame 200 assembly may include a circuit board (not shown), and the circuit board includes a plurality of sub-circuit boards stacked on each other. The transmission line 304 may be arranged on the circuit board, and a plurality of other components and devices may also be arranged on the circuit board. When the routing of the transmission line 304 conflicts with these components and devices, it may be selected to avoid the component arrangement while being as close to the antenna radiator as possible.
[0065] In the present disclosure, at least part of the transmission line 304 may be routed on a sub-circuit board located in the middle layer among the plurality of sub-circuit boards. For example, various components may be arranged on the circuit board, and the layout positions of these components may overlap with the routing of the transmission line 304, so that both the transmission line 304 and the components may be interfered or affected.
[0066] According to the configuration disclosed herein, a portion of the transmission line 304 that overlaps with the components can be routed to a sub-circuit board located on the middle layer, so that the transmission line 304 and the components can be prevented from influencing each other, thereby allowing the SAR sensor to sense a more accurate SAR value.
[0067] However, the present disclosure is not limited thereto, and in some embodiments, components may also be arranged on a sub-circuit board located in the middle layer.
[0068] In some embodiments, the signal line of the antenna used to transmit the antenna radiation signal can also be set in the circuit board. In this case, the signal line of the antenna can be set in a sub-circuit board located on the surface layer among the multiple sub-circuit boards, and the part of the transmission line 304 adjacent to the signal line is set in a sub-circuit board located in the middle layer among the multiple sub-circuit boards. Such a setting ensures that the straight-line distance between the transmission line 304 and the antenna radiator does not increase, thereby ensuring the efficiency and accuracy of the signal transmitted by the transmission line 304.
[0069] In some embodiments, the signal line of the antenna may be arranged on the sub-circuit board located at the middle layer, and the transmission line 304 may be arranged on the sub-circuit board located at the surface layer.
[0070] In an exemplary embodiment of the present disclosure, the circuit board may further include a through hole, and the transmission line 304 may be routed through the through hole to the sub-circuit board located at the middle layer.
[0071] In the present disclosure, the circuit board may further include a screw hole. In such an embodiment, the transmission line 304 may bypass the screw hole along the side wall of the perforation. For example, the transmission line 304 may bypass the perforation along the side wall of the perforation close to the antenna radiator. With such a configuration, the distance between the transmission line 304 and the antenna radiator does not increase.
[0072] In the present disclosure, the middle frame 200 may include a first area and a second area, the control unit 303 may be arranged in the first area, and the transmission line 304 may be arranged in the second area. In the present disclosure, the area where the control unit 303 is arranged may also be considered as the first area, and the area where the transmission line 304 is arranged may also be considered as the second area. In the present disclosure, the area where the control unit 303 is arranged and the area around the control unit 303 may also be considered as the first area, and the area where the transmission line 304 is arranged and the area around the transmission line 304 may also be considered as the second area.
[0073] In the present disclosure, in the working state of the middle frame assembly 10, the temperature of at least a part of the second area does not change with the temperature change of the first area. In the present disclosure, the so-called working state of the middle frame assembly 10 can be considered as the use state of the middle frame assembly 10. For example, when the middle frame assembly 10 is set in an electronic device, any operation of the user on the electronic device (for example, playing video, audio, turning on a flashlight, shooting, etc.) can be considered as the working state of the middle frame assembly 10.
[0074] In the present disclosure, when the middle frame assembly 10 is in working state, the components arranged on the middle frame assembly 10 may generate heat, thereby forming a corresponding heating area on the middle frame 200. In different working states, the heating area on the middle frame 200 is different.
[0075] In the present disclosure, the temperature of at least a portion of the second region does not change with the temperature of the first region. The first region may generate heat in some working conditions, while a portion of the second region or the entire region does not generate heat.
[0076] In the present disclosure, when the middle frame assembly 10 is in working state, the heat generated in the first area affects the control unit 303. Since a part of the second area does not generate heat or the entire area does not generate heat, the transmission line 304 disposed in the second area will not be affected by the temperature change. Such a setting ensures that even if the control unit 303 is affected by the temperature change, the transmission line 303 will not be affected by the temperature change, thereby ensuring that the sensing data transmitted to the control unit 303 is accurate. Based on this, the SAR value sensed by the SAR sensor is accurate, and the control and adjustment of the antenna made according to such a SAR value is accurate.
[0077] For example, when the SAR value sensed by the SAR sensor is greater than the actual SAR value, the electronic device will control to shut down part of the antenna, which will cause the antenna to be shut down when it is not necessary, causing the electronic device to lose the antenna's radiation range. When the SAR value sensed by the SAR sensor is less than the actual SAR value, the human body will be damaged by radiation because the antenna cannot be shut down in time.
[0078] The configuration disclosed herein can obtain accurate SAR values, so that the electronic device can make appropriate judgments and adjustments.
[0079] It should be noted that the above discussion discusses the case where the first area is heated, but does not exclude the case where the temperature of the first area is reduced. A temperature reduction will also lead to inaccurate SAR values. In the configuration disclosed herein, when the temperature of the first area is reduced, the temperature of the second area does not decrease accordingly, so the influence of the temperature reduction on the SAR value can also be avoided.
[0080] The above embodiment states that the temperature of the second region does not change with the temperature of the first region, but the present disclosure is not limited thereto. In some embodiments, the temperature of the second region may also change.
[0081] In the present disclosure, the temperature change radius of at least a part of the second region corresponds to the temperature change radius of the first region. The temperature change radius described in the present disclosure, on the one hand, refers to the same trend of temperature change, that is, when the temperature of the first region increases, the temperature of the second region also increases, and when the temperature of the first region decreases, the temperature of the second region also decreases. On the other hand, when the temperature of the first region increases by a certain value, the range of temperature increase in the second region is similar to that of the first region. For example, if the temperature of the first region increases by 6°C, then the temperature of the second region increases by 4°C, which is considered to be similar. The judgment on similar temperatures is consistent with the judgment in industrial production and daily life. Alternatively, it is determined according to the range of temperature affected by the electronic components provided on the middle frame. For example, when the temperature difference is 2°C and the same electronic component is basically unaffected, it is considered that the temperature is similar.
[0082] In the present disclosure, the case where the temperature is reduced is consistent with the case where the temperature is increased, and will not be described in detail here.
[0083] The temperature change radius of the first area and the second area is consistent, and the control unit 303 set in the first area and the transmission line 304 set in the second area are affected in the same way. Such a setting ensures that even if the control unit 303 is affected by temperature changes, the transmission line 304 is also affected by temperature changes. The effects on both are consistent, which can offset the difference caused by temperature changes, and thus ensure that the sensing data transmitted to the control unit 303 is accurate. Based on this, the SAR value sensed by the SAR sensor is accurate, and the control and adjustment of the antenna made according to such SAR value is accurate.
[0084] In the present disclosure, the temperature of a portion of the second region does not change as the temperature of the second region changes, and the temperature change amplitude of another portion of the second region is consistent with (corresponding to) the temperature change amplitude of the first region.
[0085] In the exemplary embodiment of the present disclosure, the transmission line 304 of the SAR sensor is as close to the antenna radiator as possible during wiring, so that it can be away from the heating area (heat source area) on the middle frame 200 to ensure the efficiency and accuracy of the signal transmitted by the transmission line 304.
[0086] Figure 7 is a schematic structural diagram of a middle frame assembly according to another exemplary embodiment. Figure 7 As shown, in an exemplary embodiment of the present disclosure, the antenna may include a first antenna ANT1 and a second antenna ANT0.
[0087] like Figure 7As shown, the antenna radiator includes a first antenna radiator and a second antenna radiator, the first antenna radiator is the antenna radiator of the first antenna, and the second antenna radiator is the antenna radiator of the second antenna.
