Detailed Description

To make the objects, technical solutions and advantages of the present disclosure more apparent, the present disclosure is described in further detail below with reference to the embodiments and the accompanying drawings. The exemplary embodiments and descriptions of the present disclosure are provided herein for illustration of the present disclosure, but not for limitation of the present disclosure.

The embodiments of the present disclosure provide a mobile terminal and a method for determining an antenna, and the present disclosure is described in detail below with reference to the accompanying drawings.

Fig. 1A is a schematic diagram of a mobile terminal according to an exemplary embodiment, where the mobile terminal may be a mobile phone, a tablet computer, or the like, which is not limited in this embodiment. As shown in fig. 1A, the mobile terminal includes at least: a housing 101, a processor 102, at least two antennas 103 and at least two temperature sensors 104 distributed on both sides.

The at least two antennas 103 may be disposed inside the casing 101, or may be partially disposed inside the casing 101, and partially protrude from the surface of the casing 101, which is not limited in this embodiment.

Referring to fig. 1B, at least two antennas 103 and at least two temperature sensors 104 are each connected to the processor 102. That is, the output ends of the at least two temperature sensors 104 are connected to the processor 102, and are used for sending the acquired temperature values to the processor 102. At least two antennas 103 are connected to the processor 102, and can receive signals and transmit the signals to the processor 102, or transmit the signals according to the control of the processor 102.

The present mobile terminal is generally configured with a plurality of antennas, and when it is necessary to transmit and receive signals, any one of the antennas can be selected to transmit and receive signals. However, if the user shields the antenna of the mobile terminal while holding the mobile terminal, interference may be caused to signals transmitted and received by the antenna. Therefore, in order to avoid interference, the mobile terminal may first determine a contact position between the user and the mobile terminal, and select an antenna to be used for transmitting and receiving signals from the configured multiple antennas according to the determined contact position, so as to avoid using an antenna blocked by the user.

In practical applications, if the user does not touch the mobile terminal, the temperature of the surface of the housing of the mobile terminal will be in a relatively constant state. When the user wants to use the mobile terminal, the user usually picks up the mobile terminal with a hand, and because the temperature of the fingers of the user and the temperature of the mobile terminal have a certain temperature difference, when the user holds the mobile terminal, the fingers of the user contact the surface of the frame of the shell of the mobile terminal, and the temperature of the surface of the frame will change through heat conduction. Therefore, the temperature value or the variation of the temperature value on the surface of the mobile terminal shell can reflect the contact condition of the user and the mobile terminal.

In order to facilitate determining the contact position of the user with the mobile terminal, at least two temperature sensors 104 may be configured in the mobile terminal, and the contact position of the user with the mobile terminal may be determined through temperature values acquired by the at least two temperature sensors 104.

Wherein the at least two temperature sensors 104 comprise sensing elements disposed on the surface of the housing 101 for sensing the current temperature of the mobile terminal. The configuration position of the sensing element is the sensing position of the temperature sensor.

The at least two temperature sensors 104 may be a pressure type temperature sensor, a resistance type temperature sensor, a thermocouple type temperature sensor, etc., which is not limited in this embodiment. And the sensing elements included in the different types of temperature sensors are different, for example, the sensing element of the resistance temperature sensor is a thermistor, and the sensing element of the thermocouple type temperature sensor is a thermocouple. In addition, the types of the at least two temperature sensors 104 may be the same or different, which is not limited in this embodiment.

In addition, the sensing elements of the at least two temperature sensors 104 on the mobile terminal may be uniformly distributed or non-uniformly distributed, which is not limited in this embodiment. And the at least two temperature sensors 104 may be distributed in a variety of ways. Referring to fig. 1C, the sensing elements of at least two temperature sensors 104 may be distributed on the surface of the housing in a dotted manner, i.e. each temperature sensor corresponds to one sensing position, and the temperature value at the corresponding sensing position can be obtained. Alternatively, referring to fig. 1D, the sensing elements of the plurality of temperature sensors may be distributed on the surface of the housing in a strip shape, that is, each temperature sensor corresponds to a plurality of sensing positions, and the temperature values at the plurality of sensing positions can be obtained.

In order to facilitate sensing the temperature of the frame surface of the mobile terminal when the user holds the mobile terminal, the at least two temperature sensors 104 may be distributed on two sides of the frame of the mobile terminal, that is, the at least two temperature sensors 104 include at least one first side temperature sensor 104 and at least one second side temperature sensor 104, wherein a sensing element of the first side temperature sensor 104 is configured on the first side frame surface of the casing 101, a sensing element of the second side temperature sensor 104 is configured on the second side frame surface of the casing 101 opposite to the first side frame surface, and the sensing element may sense the temperature of the frame surface of the mobile terminal, so that when the user holds the mobile terminal, the temperature sensor 104 may obtain the temperature value of the contact position between the user and the frame surface of the mobile terminal through the sensing element.

The first side frame and the second side frame may be a left side frame, a right side frame, an upper side frame, a lower side frame, etc. of the casing 101, and the first side frame and the second side frame are opposite in position, for example, if the first side frame is the left side frame, the second side frame is the right side frame, and if the first side frame is the upper side frame, the second side frame is the lower side frame, etc., which is not limited in this embodiment.

For example, taking a dotted temperature sensor as an example, referring to the left and right views provided in fig. 1E, the mobile terminal includes a plurality of temperature sensors 104, and sensing elements of the plurality of temperature sensors 104 are distributed on the left and right side frame surfaces of the housing 101.

In this embodiment, when the contact position between the user and the mobile terminal is determined by the temperature values acquired by the at least two temperature sensors 104, any one of the following modes 1 to 4 may be adopted:

mode 1, if the processor 102 determines that the temperature value sent by the at least one first-side temperature sensor and the at least one second-side temperature sensor at the current time point is different from the temperature value sent last time, determining the sensing position of the at least one first-side temperature sensor and the at least one second-side temperature sensor as the contact position of the user with the mobile terminal.

When the temperature value on the surface of the mobile terminal housing changes, it can be considered that the user is in contact with the mobile terminal, and when the temperature value on the first side housing surface and the second side housing surface of the mobile terminal changes, it can be considered that the user is in contact with the two side housing surfaces of the mobile terminal, that is, the user holds the mobile terminal. Therefore, after the processor 102 receives the temperature values transmitted by the plurality of temperature sensors 104, it may determine that the temperature values at the sensing positions of the first side temperature sensor 104 and the second side temperature sensor 104 are changed when it is determined that the temperature values transmitted by at least one first side temperature sensor 104 and at least one second side temperature sensor 104 are different from the temperature values transmitted last time, and then it may determine that the user touches the sensing positions of the first side temperature sensor 104 and the second side temperature sensor 104, and then determine the sensing positions of the at least one first side temperature sensor 104 and the at least one second side temperature sensor 104 as the contact position of the user with the mobile terminal.

Mode 2, if the processor 102 determines that the temperature values sent by the at least one first side temperature sensor and the at least one second side temperature sensor belong to a preset set of temperature values, determining the sensing positions of the at least one first side temperature sensor and the at least one second side temperature sensor as the contact positions of the user and the mobile terminal.

Since the human body temperature is generally maintained within a certain temperature range, when the user contacts the mobile terminal, the temperature at the contact position of the user with the mobile terminal should fall within the general human body temperature range. For this, the mobile terminal may predetermine a preset temperature value set according to a human body temperature value. When the temperature value sent by the temperature sensor belongs to the preset temperature value set, it can indicate that the user touches the sensing position of the temperature sensor.

Therefore, if the processor 102 determines that the temperature values sent by the at least one first side temperature sensor 104 and the at least one second side temperature sensor 104 both belong to the preset set of temperature values, indicating that the user touches the sensing positions of the first side temperature sensor 104 and the second side temperature sensor 104, the sensing positions of the at least one first side temperature sensor 104 and the at least one second side temperature sensor 104 can be determined as the contact positions of the user with the mobile terminal.

The preset temperature value set may include a continuous temperature value range, or may further include one or more discrete temperature values, for example, the preset temperature value set may be {36.4 ℃ -37.4 ℃ }, may also be {36 ℃, 36.5 ℃, 37 ℃, 37.5 ℃ }, or {36.4 ℃ -37 ℃, 37.2 ℃ }, and the like, which is not limited in this embodiment.

In addition, since the human body temperature changes with time, the range to which the human body temperature belongs may also be different according to the time period. For example, during each day, the temperature of the human body is generally lowest at about 3:00 am, and rises from about 3:00 am, rises to the highest at about 3:00 pm, and then falls from about 3:00 pm. Then, in order to reduce the error caused by the time factor, the processor 103 may determine a preset temperature value set corresponding to each time period in advance according to the human body temperature range of each time period, so as to establish a corresponding relationship between the time periods and the preset temperature value set. The preset temperature value sets corresponding to different time periods may be different or the same, and this embodiment does not limit this.

Then, if the processor 102 determines that the temperature values sent by the at least one first side temperature sensor 104 and the at least one second side temperature sensor 104 both belong to the preset temperature value set corresponding to the time period to which the current time point belongs, the sensing positions of the at least one first side temperature sensor 104 and the at least one second side temperature sensor 104 are determined as the contact position of the user with the mobile terminal.

Mode 3, if the processor 102 determines that the temperature values sent by the at least one first-side temperature sensor and the at least one second-side temperature sensor at the current time point are different from the temperature value sent last time, and the temperature values sent at the current time point both belong to a preset temperature value set, determining the sensing positions of the at least one first-side temperature sensor and the at least one second-side temperature sensor as the contact positions of the user and the mobile terminal, where the preset temperature value set is set according to the human body temperature value.

Even if the user does not contact the mobile terminal, the temperature of the case surface of the mobile terminal may be slightly changed according to the change of the external environment, the temperature value obtained by the temperature sensor will also slightly change, so in order to improve the detection accuracy, reduce the error caused by the external environment, modes 1 and 2 above may be combined, that is, the processor 102 may determine that the temperature value sent by the at least one first-side temperature sensor and the at least one second-side temperature sensor at the current time point is different from the last temperature value sent, and when the temperature values sent at the current time point all belong to the preset temperature value set, determining the sensing positions of the first side temperature sensor 104 and the second side temperature sensor 104 contacted by the user, and determining the sensing positions of the at least one first side temperature sensor 104 and the at least one second side temperature sensor 104 as the contact positions of the user and the mobile terminal.

Mode 4, if the processor 102 determines that the temperature values sent by the at least one first side temperature sensor and the at least one second side temperature sensor at the current time point are different from the temperature value sent last time, calculating a first side temperature difference between the temperature value sent by the at least one first side temperature sensor at the current time point and the temperature value sent last time, and calculating a second side temperature difference between the temperature value sent by the at least one second side temperature sensor at the current time point and the temperature value sent last time; and if the at least one first side temperature difference and the at least one second side temperature difference are determined to belong to the preset temperature difference set, determining the sensing positions of the at least one first side temperature sensor and the at least one second side temperature sensor as the contact positions of the user and the mobile terminal.

Since the user is not touching the mobile terminal, the temperature of the housing surface of the mobile terminal will be close to the ambient temperature. When the user touches the mobile terminal, the human body temperature of the user is generally maintained within a certain temperature range, and the temperature of the surface of the housing changes through heat conduction, that is, when the user touches the mobile terminal, a temperature difference is caused on the surface of the housing of the mobile terminal, and the temperature difference should belong to a range of the temperature difference between the human body temperature and the temperature of the mobile terminal.

For this, the mobile terminal may predetermine a preset temperature difference set, which is set according to a human body temperature value. When the temperature difference between the temperature value sent by the temperature sensor at the current time point and the temperature value sent last time belongs to the preset temperature value set, it can indicate that the user touches the sensing position of the temperature sensor.

Therefore, if the processor 102 determines that the temperature values transmitted by the at least one first side temperature sensor and the at least one second side temperature sensor at the current time point are different from the temperature values transmitted last time, calculating a temperature difference between the temperature value transmitted at the current point in time and the temperature value transmitted last time for the at least one first side temperature sensor and the at least one second side temperature sensor, resulting in at least one first side temperature difference and at least one second side temperature difference, if it is determined that the at least one first side temperature difference and the at least one second side temperature difference both belong to the preset temperature difference set, determining the sensing positions of the at least one first side temperature sensor 104 and the at least one second side temperature sensor 104 contacted by the user, and determining the sensing positions of the at least one first side temperature sensor and the at least one second side temperature sensor as the contact positions of the user and the mobile terminal.

The preset temperature difference set may include a continuous temperature difference range, or may further include one or more discrete temperature differences, for example, the preset temperature difference set may be {16.4 ℃ -17.4 ℃ }, may also be {16.4 ℃, 16.8 ℃, 17 ℃, 17.4 ℃ }, or {16.4 ℃ -17 ℃, 17.2 ℃ }, and the like, which is not limited in this embodiment.

In addition, since the ambient temperature may vary with time, for example, the ambient temperature may vary with seasons in a year, the ambient temperature may vary with day and night in a day, and the temperature of the mobile terminal may also vary with the ambient temperature. Therefore, the temperature of the mobile terminal may be different according to the time point.

Therefore, in order to improve the detection accuracy and reduce the error caused by the external environment, the processor 103 may set a preset temperature difference set corresponding to each time period in advance according to the temperature difference between the ambient temperature value and the human body temperature value of each time period, so as to establish the corresponding relationship between the plurality of time periods and the preset temperature difference set. The preset temperature difference sets corresponding to different time periods may be different or the same, and this embodiment does not limit this.

Then, if the processor 103 determines that the at least one first-side temperature difference and the at least one second-side temperature difference both belong to a preset set of temperature differences corresponding to a time period to which the current time point belongs, the sensing positions of the at least one first-side temperature sensor and the at least one second-side temperature sensor are determined as the contact position of the user with the mobile terminal.

The mobile terminal provided by the embodiment obtains the temperature value of the mobile terminal through the at least two temperature sensors distributed on the two sides, and can determine the antenna to receive the signal according to a plurality of contact positions of the user and the mobile terminal when the user holds the mobile terminal, so that the interference to the signal received and transmitted by the antenna due to the fact that the user shields the antenna is avoided, and the function of receiving and transmitting the signal of the mobile terminal is avoided being influenced.

In another embodiment, after determining a plurality of contact positions of the user with the mobile terminal, the processor 102 may select an antenna farther from the plurality of contact positions from the plurality of antennas to transmit and receive signals according to the plurality of contact positions, so as to avoid interference caused by the user to the signals transmitted and received by the antennas.

For example, the processor 103 may count the plurality of contact positions to obtain a center contact position of the plurality of contact positions, and determine an antenna farthest from the center contact position among the plurality of antennas as an antenna to transmit and receive signals.

The processor 103 may establish a coordinate system, calculate an average coordinate according to coordinates of the plurality of contact positions in the coordinate system, and use a position corresponding to the calculated average coordinate as the center contact position, or select a contact position located at the center from the plurality of contact positions according to coordinates of the plurality of contact positions in the coordinate system, that is, a position with a smaller distance from other contact positions, as the center contact position.

In addition, considering that when the user holds the mobile terminal, it is most likely that the palm of the user shields the antenna, and the contact position of the thumb of the five fingers with the mobile terminal can better reflect the position of the palm of the user, so in order to avoid the palm of the user shielding the antenna, the processor 103 may determine the antenna to receive the signal according to the contact position of the thumb and the mobile terminal.

Since the contact position of the thumb with the mobile terminal and the contact position of the other fingers with the mobile terminal are usually located on different sides when the user holds the mobile terminal. Therefore, after the processor 103 determines a plurality of contact positions of the user and the mobile terminal, it may determine a surface of the rim where each contact position is located, and if it is determined that a first contact position of the plurality of contact positions and other contact positions are located on different sides of the surface of the rim, which means that the first contact position is a contact position of the user thumb and the mobile terminal, determine an antenna farthest from the first contact position among the plurality of antennas as an antenna to receive and transmit signals.

Wherein, first contact position and other contact position can include on being located the frame surface of different sides: the first contact position is located on the first side frame surface, and the other contact positions except the first contact position are located on the second side frame surface. Alternatively, the first contact position is located on the second side frame surface, and other contact positions except the first contact position are located on the first side frame surface, and the like, which is not limited in this embodiment.

For example, when the user holds the mobile terminal with his thumb at a lower position of the mobile terminal, indicating that the palm of the user is located below the mobile terminal and possibly blocking the lower antenna, the upper antenna is selected to transmit and receive signals. When the user holds the mobile terminal and the thumb is located at the upper position of the mobile terminal, the palm of the user is located above the mobile terminal, the upper antenna is likely to be shielded, and the lower antenna is selected to transmit and receive signals.

Of course, the processor 103 may also determine the antenna to receive the signal in other manners according to a plurality of contact positions of the user and the mobile terminal, which is not limited in this embodiment, and it is only required to ensure that the determined antenna is farther from the plurality of contact positions than other antennas.

In another embodiment, the processor 102 may start at least two temperature sensors in real time, and obtain the temperature value of the mobile terminal by the at least two temperature sensors, so as to determine an antenna to receive signals, and then transmit and receive signals based on the determined antenna when receiving a service request. Alternatively, to avoid consuming excessive power and save resources, the processor 102 may activate the at least two temperature sensors only when receiving a request for a signal transmission and reception service.

The service request for receiving and transmitting signals refers to a service request that needs to receive or transmit signals, and may be triggered by the processor 102, or triggered by a user performing an operation of receiving and transmitting signals, or triggered by other elements on the mobile terminal, which is not limited in this embodiment. When the processor 102 receives the service request of transceiving signals, the at least two temperature sensors are started, the antenna to receive signals is determined according to the temperature values acquired by the at least two temperature sensors, and the signals are received or transmitted based on the determined antenna so as to respond to the service request of transceiving signals.
