Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of electronic devices, and particularly relates to an electronic device and a control method. BACKGROUND

[0002] Internationally, the specific absorption ratio (SAR) is used to measure the energy absorbed by the human body from mobile phone radiation. Currently, various national regulations have corresponding requirements for the SAR value, and manufacturers usually use the method of reducing the conduction power to control the SAR value of the device to meet the regulations. In order to improve the user experience, a SAR sensor module can be introduced on the electronic device, and different combinations of SAR sensors can be used to realize the judgment of multiple scenes on the software, thereby reducing the decline of the antenna performance in actual use as much as possible under the premise of meeting the SAR regulations. The SAR sensor usually uses an antenna suspended outside the main ground of the electronic device as a sensing body, and judges whether the human body is close by judging whether the change amount of the capacitance between the human body and the SAR sensor sensing sheet reaches a threshold value, and then calls a set of NV to reduce the conduction power.

[0003] Generally, the greater the sensing distance of the sensing antenna, the better the performance of the electronic device in the state of not triggering the power reduction, so the sensing distance of the sensing antenna is a key parameter of the SAR sensor. Currently, the SAR sensor mainly uses a certain fixed transmitting antenna as a sensing body, and once the area of the antenna is determined, it cannot be changed. The trend of thinning of electronic devices limits the size of the antenna radiator, resulting in insufficient projection area of the sensing antenna, so that the sensing distance cannot meet the actual demand.

DETAILED DESCRIPTION

Based on the embodiments in the application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the application.

It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of a kind and do not limit the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / " generally indicates that the front and rear associated objects are in an "or" relationship.

[0037] The electronic device and control method provided by the embodiments of the present application will be described in detail below with specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0038] Referring to Figures 1 to 15 The electronic device provided by the embodiments of the present application includes: a first shell b1 and a second shell b2, the first shell b1 is movably connected with the second shell b2; the first shell b1 includes a first radiator 1, and the second shell b2 includes a second radiator 2; when the first shell b1 is in a contracted state relative to the second shell b2, the first radiator 1 is connected with the second radiator 2 through a conductive part; when the first shell b1 is in an expanded state relative to the second shell b2, the first radiator 1 and the second radiator 2 have a first distance in a first direction, and the first direction is parallel to the relative movement direction of the first shell b1 and the second shell b2.

[0039] The electronic device further includes: a specific absorption rate (SAR) sensor 3; the SAR sensor 3 is connected with the first radiator 1 and the second radiator 2 respectively; or the SAR sensor 3 is connected with the first radiator 1, the first radiator 1 is connected with the second radiator 2 through a first circuit, and in the expanded state, the first circuit is a pass, and in the contracted state, the first circuit is a break.

[0040] In the above embodiments, the sensing areas corresponding to the contracted state and the expanded state are different, so that the contracted state and the expanded state correspond to two sensing distances. Moreover, when the SAR sensor 3 is connected with the first radiator 1 and the second radiator 2 respectively and the electronic device is in the contracted state, the sensing distance of the SAR sensor can be increased, and the performance of the antenna after SAR reduction in the contracted state can be improved; when the SAR sensor 3 is connected with the first radiator 1 and the first radiator 1 is connected with the second radiator 2 through the first circuit, the sensing distance of the SAR sensor can be increased when the electronic device is in the expanded state, and the performance of the antenna after SAR reduction in the expanded state can be improved.

[0041] Specifically, the connection mode of the SAR sensor 3 with the first radiator 1 and / or the second radiator 2 will be introduced below. It can mainly include the following two schemes:

[0042] Scheme one:

[0043] In an embodiment of the present application, the first circuit includes an inductive element and a switching element connected in series, and one end of the first circuit is electrically connected to the first radiator 1, and the other end of the first circuit is electrically connected to the second radiator 2; the electronic device further includes a controller configured to output a control signal to the switching element to control the switching element to switch between a conduction state and a disconnection state.

[0044] Specifically, the first circuit is arranged on the control mainboard.

[0045] As an implementation manner, in the first aspect, Figures 3 to 5 In the first aspect, the first shell b1 includes a first part b11 and a second part b12; the second part b12 includes the first radiator 1; in the collapsed state, the second part b12 is collapsed into the second shell b2, and the first radiator 1 and the second radiator 2 are superimposed and connected by the conductive part.

[0046] Optionally, in the collapsed state, the first radiator 1 and the second radiator 2 are connected by exposed metal; in the unfolded state, the first radiator 1 and the second radiator 2 have a first distance in the first direction, and are connected by the first circuit.

[0047] Exemplarily, in the unfolded state, the first radiator 1 and the second radiator 2 are separated, and the first radiator 1 and the second radiator 2 are processed in direct current isolation. The SAR sensor 3 is connected to the first radiator 1, and the first radiator 1 and the second radiator 2 are connected by a mainboard trace, and the mainboard trace has a high-frequency isolation circuit and a switch.

[0048] Specifically, in the unfolded state, Figure 7 In the first aspect, the first radiator 1 and the second radiator 2 are separated in the first direction, and the first radiator 1 and the second radiator 2 are connected by the first circuit. The inductance is connected in series near the inductive unit at both ends of the first circuit, and the electric energy can isolate the radio frequency signal, avoid mutual interference between the first radiator 1 and the second radiator 2, and a switching element is arranged in the middle of the first circuit, and the switching element is controlled to be on or off by a control signal; wherein, when it is identified that the electronic device is in the unfolded state, the switching element is turned on, and the low-frequency equivalent first radiator 1 and the second radiator 2 are directly connected. The SAR sensor 3 is connected to the first radiator 1 through a section of isolation circuit, and the sensing distance of the SAR sensor 3 is L12 at this time.

[0049] Exemplarily, in the first aspect, Figure 2In the contracted state, the SAR sensor 3 is connected to the first radiator 1, and the first radiator 1 and the second radiator 2 are directly contacted in the direction perpendicular to the flexible screen 100 through the conductive part, such as the direct connection through the exposed metal. The first radiator 1 and the second radiator 2 radiate as a whole. As shown in FIG. 2a. Figure 8 In the contracted state, the first radiator 1 and the second radiator 2 are directly connected, and the SAR sensor 3 is connected to the first radiator 1 through a section of isolation circuit, and the sensing distance of the SAR sensor 3 is L1 at this time.

[0050] It should be noted that the SAR sensor is essentially a sensor for detecting the capacitance value of the sensing antenna. According to the formula for calculating the capacitance: C = εS / 4πkd, under the condition of a certain capacitance C, cascading the first radiator 1 and the second radiator 2 can increase the equivalent projection area S, and the sensing distance d of the sensing surface will also increase, so L12 > L1.

[0051] In this mode, the SAR sensor can increase the sensing distance in the expanded state by cascading the first radiator 1 and the second radiator 2. Moreover, two sets of SAR parameters can be called respectively in the expanded state and the contracted state, so as to improve the antenna performance in the expanded state. The sacrifice of the antenna performance in the expanded state caused by sharing the fixed SAR parameters is avoided.

[0052] Based on the above-mentioned scheme one, the relationship between the first radiator 1 and the second radiator 2 can include the following three modes:

[0053] Mode one:

[0054] In an embodiment, in the expanded state, the first feeding point of the first radiator 1 is connected to the feeding 10 of the first antenna, the feeding point of the second radiator 2 is connected to the ground, and the second radiator 2 is not connected to the feeding.

[0055] As shown in FIG. 2b, Figure 9 In the contracted state, the first radiator 1 and the second radiator 2 are stacked up and down, and the two can be directly connected through the exposed metal surface. The first radiator 1 and the second radiator 2 form an antenna radiator as a whole, and are fed through the feeding 10 of the first antenna.

[0056] As shown in FIG. 2c, Figure 10 In the expanded state, the first radiator 1 and the second radiator 2 are separated, the first radiator 1 is fed through the feeding 10 of the first antenna and is processed as a direct current isolation ground, the second radiator 2 is only processed as a direct current isolation ground and is not connected to the feeding. In this way, the first radiator 1 works, the second radiator 2 does not serve as a new antenna radiator and is not part of the first radiator 1, and has no effect on the performance of the first radiator 1.

[0057] Mode two:

[0058] In one embodiment, in the deployed state, the first feed point of the first radiator 1 is connected to the feed point 10 of the first antenna, and the second radiator 2 is fed to the first radiator 1 via electromagnetic coupling.

[0059] like Figure 9 In the contracted state, the first radiator 1 and the second radiator 2 are stacked one on top of the other. The two can be directly connected through the exposed metal surface. The first radiator 1 and the second radiator 2 are a whole to form an antenna radiator, and are fed by the first antenna feed 10.

[0060] like Figure 10 In the deployed state, the first radiator 1 and the second radiator 2 are separated. The first radiator 1 is fed through the feed 10 of the first antenna and is treated as a DC isolated ground. The second radiator 2 is treated as a DC isolated ground and is not connected to the feed. The second radiator 2 acts as a parasitic unit of the first radiator 1 and is fed by electromagnetic coupling.

[0061] It should be noted that, since the second radiator 2 in the deployed state is a parasitic branch of the first radiator 1, it will have an increase in the radiation performance of the first radiator 1. Therefore, the antenna performance in the deployed state is better than that in the retracted state, and the SAR value in the deployed state is higher. After calling the SAR reduction parameter, the antenna performance in the deployed state is better than that in the retracted state.

[0062] Method 3:

[0063] In one embodiment, in the deployed state, the first feed point of the first radiator 1 is connected to the feed 10 of the first antenna, and the second feed point of the second radiator 2 is connected to the feed 20 of the second antenna.

[0064] like Figure 11 In the contracted state, the first radiator 1 and the second radiator 2 are stacked one on top of the other. The two can be directly connected through the exposed metal surface. The first radiator 1 and the second radiator 2 are a whole to form an antenna radiator, and are fed by the first antenna feed 10.

[0065] like Figures 3 to 4 In the deployed state, the first radiator 1 and the second radiator 2 are separated. The first radiator 1 is fed through the feed 10 of the first antenna and is treated as a DC isolated ground; the second radiator 2 is fed through the feed 20 of the second antenna and is treated as a DC isolated ground. At this time, the second radiator 2 is not part of the first radiator 1 and does not affect the performance of the first radiator 1.

[0066] In this mode, the original performance of the first radiator 1 in the expanded state is unchanged, and the second radiator 2 is newly added as a transmitting antenna. Since the first radiator 1 and the second radiator 2 are connected in series through a piece of wire, the SAR sensor can act on the first radiator 1 and the second radiator 2 at the same time. In this way, the sensing distance in the expanded state is higher, and the SAR value is higher. After the SAR reduction parameter is called, the antenna performance in the expanded state is better than that in the contracted state.

[0067] Scheme two:

[0068] In another embodiment of the present application, the SAR sensor 3 is connected to the first radiator 1 through a first line and connected to the second radiator 2 through a second line.

[0069] As Figure 13 In the first shell b1 includes a first part b11 and a second part b12; the first part b11 includes the first radiator 1; in the contracted state, the second part b12 is contracted to the inside of the second shell b2, the first part b11 is in contact with the second shell b2, the first side of the first radiator 1 is connected to the second side of the second radiator 2 through the conductive part, and the first radiator 1 and the second radiator 2 are connected side by side in the first direction.

[0070] As Figure 14 and Figure 12 In the first shell b1 includes a first part b11 and a second part b12; the first part b11 includes the first radiator 1; in the contracted state, the second part b12 is contracted to the inside of the second shell b2, the first part b11 is in contact with the second shell b2, the first side of the first radiator 1 is connected to the second side of the second radiator 2 through the conductive part, and the first radiator 1 and the second radiator 2 are connected side by side in the first direction.

[0071] As Figures 12 to 13 In the expanded state, the first radiator 1 and the second radiator 2 have a first distance in the first direction, i.e. the first metal surface 11 and the second metal surface 21 are separated, the first radiator 1 and the second radiator 2 are connected to the SAR sensor 3 through independent lines, and the first radiator 1 and the second radiator 2 serve as independent transmitting antennas.

[0072] Specifically, as Figure 15 In the first shell b1 includes a first part b11 and a second part b12; the first part b11 includes the first radiator 1; in the contracted state, the second part b12 is contracted to the inside of the second shell b2, the first part b11 is in contact with the second shell b2, the first side of the first radiator 1 is connected to the second side of the second radiator 2 through the conductive part, and the first radiator 1 and the second radiator 2 are connected side by side in the first direction.

[0073] In the embodiment, in the contracted state, the first radiator 1 multiplexes the second radiator 2 through the exposed metal connection, so that the sensing distance of the SAR sensor in the contracted state can be increased. Moreover, two sets of SAR parameters in the expanded state and the contracted state can be called respectively, so that the antenna performance in the contracted state is improved. The sacrifice of the antenna performance in the contracted state caused by sharing the fixed SAR parameter is avoided.

[0074] participate Figure 16 The embodiment of the present application provides a control method applied to the electronic device, and the method specifically comprises the following steps.

[0075] In step 101, when it is determined that the first shell b1 is in the contracted state relative to the second shell b2, the SAR sensor 3 is controlled to call the first SAR parameter and the first power parameter.

[0076] In step 102, when it is determined that the first shell b1 is in the expanded state relative to the second shell b2, the SAR sensor 3 is controlled to call the second SAR parameter and the second power parameter.

[0077] In the embodiment, because the first shell b1 is in the contracted state and the expanded state relative to the second shell b2, the SAR sensor has two sensing distances corresponding to two antenna states respectively, so that two sets of SAR parameters in the expanded state and the contracted state are called respectively, and the antenna performance in the contracted state is improved. The sacrifice of the antenna performance in the contracted state or the expanded state caused by sharing the fixed SAR parameter is avoided.

[0078] In an embodiment, in the case that the SAR sensor 3 is connected with the first radiator 1, and the first radiator 1 is connected with the second radiator 2 through the first circuit, the method further comprises the following steps.

[0079] When it is determined that the first shell b1 is in the contracted state relative to the second shell b2, the controller controls the first circuit to be disconnected.

[0080] When it is determined that the first shell b1 is in the expanded state relative to the second shell b2, the controller controls the first circuit to be connected.

[0081] In a specific embodiment, in the case that the SAR sensor 3 is connected with the first radiator 1, and the first radiator 1 is connected with the second radiator 2 through the first circuit, and the first circuit is provided with a switching element, the method further comprises the following steps.

[0082] When it is determined that the first shell b1 is in the contracted state relative to the second shell b2, the controller outputs a first signal, and the first signal is used to control the switching element to be disconnected.

[0083] When it is determined that the first shell b1 is in the unfolded state relative to the second shell b2, the controller outputs a second signal for controlling the switch element to be turned on.

[0084] As Figure 17 In the embodiment, the control method mainly includes: the electronic device is working, and it is judged whether it is in the unfolded state; if yes, the switch is turned on, and the first SAR parameter is called; if no, the switch is turned off, and the second SAR parameter is called.

[0085] In the embodiment, when it is determined that the first shell b1 is in the folded state relative to the second shell b2, the switch between the first radiator 1 and the second radiator 2 is turned on, the SAR sensor corresponds to the sensing distance of the folded state, the SAR parameter of the folded state is called, and the power reduction parameter (the first power parameter) of the folded state is called.

[0086] When it is determined that the first shell b1 is in the unfolded state relative to the second shell b2, the switch between the first radiator 1 and the second radiator 2 is turned off, the SAR sensor corresponds to the sensing distance of the unfolded state, the parameter of the unfolded state is called, and the power reduction parameter (the second power parameter) of the unfolded state is called, corresponding to the performance after the power reduction of the unfolded state. In this way, the sacrifice of the antenna performance in the unfolded state caused by sharing the fixed SAR parameter is avoided.

[0087] In addition, referring to Figure 12 , based on the embodiments shown in Figure 13 and Figure 18 , the control method includes: the electronic device is working, and it is judged whether it is in the unfolded state; if yes, the detection channel 0 and the detection channel 1 of the SAR sensor are independently working, and the first SAR parameter is called; if no, the detection channel 0 of the SAR sensor is working, and the detection channel 1 is set to high resistance, and the second SAR parameter is called.

The program or instructions are executed by the processor 1801 to implement each step of the above-mentioned control method embodiment, and achieve the same technical effect. To avoid repetition, it will not be described here.
