[0030] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0031] In order to better understand the embodiments of the present application, the relevant technologies are first introduced below.

[0032] In order to control the temperature of the mobile terminal within a reasonable range, different temperature control methods may be adopted, such as temperature control based on the temperature value of the chip, temperature control based on the temperature value of the outer surface of the mobile terminal, etc.

[0033] In the case of temperature control based on the temperature value of the outer surface of the mobile terminal, it is necessary to determine the temperature value of the outer surface of the mobile terminal. In order to determine the temperature value of the outer surface of the mobile terminal, temperature sensors can be set at different positions of the mainboard of the mobile terminal, and then the temperature value of the outer surface of the mobile terminal can be determined based on the temperature values ​​collected by these temperature sensors.

[0034] Since the temperature sensors on the mainboard are separated from the outer surface of the mobile terminal by thermal conductive gel, shielding cover, heat dissipation material, middle frame module, air gap, screen module, etc., the conduction distance and thermal resistance between these temperature sensors and the outer surface of the mobile terminal are large. When external factors interfere with the temperature of the outer surface, these temperature sensors cannot capture the changes in the temperature value of the outer surface of the mobile terminal in time, so that the temperature value of the outer surface of the mobile terminal cannot be accurately determined according to the actual situation.

[0035] Figure 1 : is a flow chart of a temperature determination method provided in an embodiment of the present application. The temperature determination method can be applied to a mobile terminal. The mobile terminal may include a screen module, a first temperature sensor, a heating device, and a second temperature sensor. The first temperature sensor is arranged on the inner surface of the screen module. The second temperature sensor is arranged at a position corresponding to the heating device. The mobile terminal may be a mobile terminal with a screen such as a mobile phone or a tablet computer. Figure 1 As shown, the temperature determination method may include the following steps.

[0036] 101. Collect the temperature value of the screen module through a first temperature sensor.

[0037] The mobile terminal may collect the temperature value of the screen module through the first temperature sensor in real time or periodically.

[0038] Since the first temperature sensor is arranged on the inner surface of the screen module, the temperature value of the screen module is the temperature value of the inner surface of the screen module, that is, the temperature value of the inner surface of the screen module.

[0039] For example, Figure 2 is a schematic diagram of the structure of a first temperature sensor provided in an embodiment of the present application. Figure 2 As shown, the first temperature sensor may include a pull-up resistor R1 and a thermistor thin film resistor R2. One end of the pull-up resistor R1 is electrically connected to one end of the thermistor thin film resistor R2. The other end of the pull-up resistor R1 is electrically connected to a power supply, and the other end of the thermistor thin film resistor R2 is electrically connected to a ground terminal. The pull-up resistor R1 may be a conventional resistor or a non-thermosensitive thin film resistor.

[0040] The thickness of the thermistor thin film resistor R2 may be less than or equal to 500 nanometers (Nanometer, nm). The thermistor thin film resistor R2 may be a negative temperature coefficient (NTC) thermistor thin film resistor, that is, the resistance of the thermistor thin film resistor R2 decreases as the temperature increases. The relationship between the resistance of the thermistor thin film resistor R2 and the temperature may be a nonlinear relationship. The thermistor thin film resistor R2 may be made of semiconductor materials.

[0041] The thermal film resistor R2 can be installed on the inner surface of the screen module by pasting, or can be installed on the inner surface of the screen module by integration. For example, the thermal film resistor R2 can be pasted on the inner surface of the screen module in the form of a flexible printed circuit board (FPC). For example, the thermal film resistor R2 and the copper foil layer of the screen module are made into an integrated structure.

[0042] It should be understood that the above is an exemplary description of the structure of the first temperature sensor and does not limit it.

[0043] 102. Collect the temperature value of the heating device through a second temperature sensor.

[0044] The mobile terminal may collect the temperature value of the heating device through the second temperature sensor in real time or periodically.

[0045] In order to accurately collect the temperature value of the heating device through the second temperature sensor, the second temperature sensor may be arranged at a position close to the heating device, or may be integrated on the heating device.

[0046] The heat generating device is a device that can generate heat in a mobile terminal. The heat generating device can be a processor, a power amplifier (PA) device, a WIFI device, a power management integrated circuit (PMIC) device, a charging device, or other devices that can generate heat. The processor can be a central processing unit (CPU), a graphics processing unit (GPU), other processors, or multiple processors. The PA device can be a fourth generation mobile communication technology (4G) PA device, a fifth generation mobile communication technology (5G) PA device, or other generations of mobile communication technology PA devices. The heat generating device can also be called a heat generating chip.

[0047] The heating device can be integrated on the mainboard. Accordingly, the second temperature sensor can be integrated on the mainboard.

[0048] The heating device may also be integrated on the battery protection board. Accordingly, the second temperature sensor may be integrated on the battery protection board.

[0049] The heating device can also be integrated on the small board. Correspondingly, the second temperature sensor can be integrated on the small board.

[0050] 103. Determine a temperature value of an outer surface of the mobile terminal according to a temperature value of the screen module and a temperature value of the heating device.

[0051] The mobile terminal can determine the temperature value of the outer surface of the mobile terminal according to the temperature value of the screen module and the temperature value of the heating device.

[0052] The mobile terminal may perform a weighted summation of the temperature value of the screen module and the temperature value of the heating device to obtain the temperature value of the outer surface of the mobile terminal.

[0053] It can be seen that when determining the temperature value of the outer surface of the mobile terminal, not only the influence of the temperature value of the heating device on it is considered, but also the influence of the temperature value of the screen module on it is considered. When external factors interfere with the temperature of the outer surface, since the distance between the temperature sensor arranged on the inner surface of the screen module and the outer surface of the mobile terminal is relatively close, the thermal resistance between the outer surface of the mobile terminal and the temperature sensor is relatively small. The temperature sensor can quickly capture the change of the temperature of the outer surface of the mobile terminal, that is, the temperature value of the screen module collected by the temperature sensor changes with the change of the temperature value of the outer surface of the mobile terminal, that is, the temperature sensor can capture the influence of the transient temperature of the outer surface caused by the short-term interference of external factors on the mobile terminal, and can realize accurate and timely tracking and detection of the temperature of the outer surface of the mobile terminal. Therefore, the temperature of the outer surface of the mobile terminal can be accurately determined.

[0054] In some embodiments, the number of the heating devices and the second temperature sensors are multiple. The multiple heating devices correspond to the multiple second temperature sensors one by one, that is, a second temperature sensor is respectively arranged at the corresponding position of each heating device. The first temperature sensor is arranged on the inner surface of the screen module corresponding to the main heating device among the multiple heating devices.

[0055] For example, Figure 3 Schematic diagram of the layout of a heating device on a motherboard provided in an embodiment of the present application. Figure 3 As shown, the heat generating devices integrated on the mainboard may include a 4G PA device, a 5G PA device, a WIFI device, a PMIC device, a charging device and a CPU. Corresponding second temperature sensors may be arranged next to or on these heat generating devices.

[0056] The main heat generating device is the main heat generating device among the multiple heat generating devices, that is, the device generating the most heat. For example, the main heat generating device may be a CPU.

[0057] In most usage scenarios of mobile terminals, such as gaming scenarios, social scenarios, video scenarios, live broadcast scenarios, etc., the maximum value of the temperature value of the outer surface of the mobile terminal is generally located at the outer surface of the screen module corresponding to the main heating device. Therefore, the first temperature sensor can be set on the inner surface of the screen module corresponding to the main heating device among the multiple heating devices. The temperature value of the outer surface of the screen module corresponding to the main heating device can be monitored and followed in real time, which can improve the accuracy and precision of the temperature value of the outer surface of the mobile terminal.

[0058] For example, Figure 4 Schematic diagram of the layout of a first temperature sensor provided in an embodiment of the present application. Figure 4As shown, the mobile terminal may include a screen module 1 and a first temperature sensor 2, the screen module 1 may include a main heating device corresponding position 3, and the first temperature sensor 2 may be arranged on the inner surface of the main heating device corresponding position 3. The first temperature sensor 2 may be arranged at the center position of the main heating device corresponding position 3, or at other positions of the main heating device corresponding position 3.

[0059] In some embodiments, a plurality of first temperature sensors are arranged in a matrix on the inner surface of the screen module. The mobile terminal can collect temperature values ​​through the plurality of first temperature sensors to obtain a plurality of temperature values, and can determine the temperature value of the screen module according to the plurality of temperature values.

[0060] There may be a plurality of first temperature sensors, and the plurality of first temperature sensors may be arranged in a matrix on the inner surface of the screen module.

[0061] For example, Figure 5 FIG. 1 is a schematic diagram of another layout of a first temperature sensor provided in an embodiment of the present application. Figure 5 As shown, the mobile terminal may include a screen module 1 and a plurality of first temperature sensors 4 , and the plurality of first temperature sensors 4 are arranged in a matrix on the inner surface of the screen module 1 .

[0062] The impact of external factors on the temperature values ​​of different outer surface locations of the mobile terminal may be different in different usage scenarios of the mobile terminal, or in the same usage scenario. Therefore, in order to timely track the temperature of different outer surface locations of the mobile terminal, multiple second temperature sensors can be set on the inner surface of the screen module.

[0063] For example, when the usage scenario of the mobile terminal requires the user to hold the mobile terminal, the user's hand will be placed on the mobile terminal, and the two hands or different fingers of the same hand will be placed at different positions on the outer surface of the mobile terminal, and the user's hand will affect the temperature of the placement position. If the temperature of the mobile terminal is lower than the temperature of the user's hand, the user's hand can heat the mobile terminal; if the temperature of the mobile terminal is higher than the temperature of the user's hand, the user's hand will cool the mobile terminal.

[0064] The mobile terminal can collect temperature values ​​through multiple first temperature sensors to obtain multiple temperature values, that is, each first temperature sensor can collect a temperature value to obtain multiple temperature values, and then the temperature value of the screen module can be determined according to the multiple temperature values.

[0065] The mobile terminal may determine the temperature value of the screen module as the maximum temperature value among the multiple temperature values, may determine the temperature value of the screen module as the minimum temperature value among the multiple temperature values, or may determine the temperature value of the screen module as the average value of the multiple temperature values.

[0066] Since the temperature value of the screen module is determined based on the temperature value collected by multiple first temperature sensors arranged on the inner surface of the screen module, the temperature values ​​at different positions on the inner surface of the screen module are taken into consideration, so real-time tracking and detection of temperature values ​​at different positions on the surface of the screen module can be achieved, thereby improving the accuracy and precision of the determined temperature value of the screen module, and further improving the accuracy and precision of the determined temperature value of the outer surface of the mobile terminal.

[0067] In some embodiments, the number of the heating device and the second temperature sensor are multiple. The multiple heating devices correspond to the multiple second temperature sensors one by one, that is, a second temperature sensor is respectively set at the corresponding position of each heating device. The mobile terminal can obtain the preset weighting coefficients of the screen module and the multiple heating devices, and can perform weighted summation on the temperature value of the screen module and the temperature values ​​of the multiple heating devices according to the preset weighting coefficients of the screen module and the multiple heating devices to obtain the temperature value of the outer surface of the mobile terminal.

[0068] The preset weighting coefficient of the screen module is a predetermined weighting coefficient of the screen module, that is, a predetermined weighting coefficient of the temperature value of the screen module, that is, a predetermined weighting coefficient of the temperature value of the screen module collected by the first temperature sensor.

[0069] The preset weighting coefficient of the heating device is a predetermined weighting coefficient of the heating device, that is, a predetermined weighting coefficient of the temperature value of the heating device, that is, a predetermined weighting coefficient of the temperature value of the heating device collected by the second temperature sensor, and also a predetermined weighting coefficient of the temperature value of the heating device collected by the corresponding second temperature sensor.

[0070] The mobile terminal stores preset weighting coefficients of the screen module and multiple heating devices. Therefore, each time the temperature value of the outer surface of the mobile terminal is determined, the mobile terminal can obtain the stored preset weighting coefficients of the screen module and multiple heating devices, and then perform weighted summation on the collected temperature value of the screen module and the temperature values ​​of the multiple heating devices according to the preset weighting coefficients of the screen module and the multiple heating devices to obtain the temperature value of the outer surface of the mobile terminal.

[0071] Since the weighting coefficients of the screen module and the heating device are predetermined, that is, the weighting coefficients of the screen module and the heating device are predetermined, the mobile terminal can quickly and accurately determine the temperature value of the outer surface of the mobile terminal based on the collected temperature value of the screen module and the temperature value of the heating device, thereby improving the efficiency and accuracy of determining the temperature value of the outer surface of the mobile terminal.

[0072] In some embodiments, the preset weighting coefficients of the screen module and the multiple heating devices can be fitted according to the temperature value of the screen module, the temperature values ​​of the multiple heating devices and the temperature value collected by the third temperature sensor, and the third temperature sensor is located on the outer surface of the mobile terminal.

[0073] The preset weighting coefficients of the screen module and the plurality of heating devices may be pre-fitted by the mobile terminal or pre-fitted by other electronic devices. The following is an example of the preset weighting coefficients of the screen module and the plurality of heating devices being pre-fitted by the mobile terminal.

[0074] The number of the third temperature sensor may be one or more. The third temperature sensor may be a thermocouple or other temperature sensors. The third temperature sensor may be attached to the outer surface of the mobile terminal.

[0075] When the number of the third temperature sensor is one, the temperature value of the outer surface of the mobile terminal is the temperature value of the location of the third temperature sensor, that is, the temperature value of the point where the third temperature sensor is attached to the outer surface of the mobile terminal.

[0076] Exemplarily, the temperature value of the outer surface of the mobile terminal collected by the third temperature sensor can be expressed as follows:

[0077] (1) or

[0078] (2)

[0079] in, is the temperature value of the outer surface of the mobile terminal, is the temperature value of the screen module collected by the first temperature sensor, T1 is the temperature value of the first heating device collected by the first second temperature sensor, T n is the temperature value of the nth heating device collected by the nth second temperature sensor, n is the number of heating devices, a1 is the preset weighting coefficient of the screen module, that is, the fitting coefficient, b1 is the preset weighting coefficient of the first heating device, b n is the preset weighting coefficient of the nth heating device. const is a constant term, which can be 0 or a value greater than 0.

[0080] In different application scenarios, the mobile terminal can respectively collect the temperature value of the screen module through the first temperature sensor, collect the temperature value of the heating device through the second temperature sensor, and obtain the temperature value of the outer surface of the mobile terminal collected by the third temperature sensor. Then, according to the temperature value of the screen module, the temperature value of the heating device and the temperature value of the outer surface of the mobile terminal in different scenarios, Formula 1 can be fitted to obtain Or, by fitting Formula 2, we can get The value and const value can then be stored The value of and const values ​​for subsequent calls. Can be a value less than 1.

[0081] In the case where there are multiple third temperature sensors, the temperature values ​​at different locations on the outer surface of the mobile terminal are the temperature values ​​at the locations of different third temperature sensors, that is, the temperature values ​​at different points on the outer surface of the mobile terminal are the temperature values ​​collected by the third temperature sensors at the corresponding points. For example, taking Formula 2 as an example, the temperature values ​​of different outer surfaces of the mobile terminal collected by multiple third temperature sensors can be expressed as follows:

[0082]

[0083] …

[0084]

[0085] Wherein, m is the number of the third temperature sensors, which is an integer greater than 1. shell1 is the temperature value of the mobile terminal at the first outer surface position, shell m is the temperature value of the mth outer surface position of the mobile terminal, a 1i is the preset weighting coefficient of the screen module corresponding to the i-th outer surface position, i.e., the fitting coefficient, b 1i is the preset weighting coefficient of the first heating device corresponding to the i-th outer surface position, b ni is the preset weighting coefficient of the nth heating device corresponding to the ith outer surface position, const i is the constant term corresponding to the i-th outer surface position. i=1,2…,m.

[0086] In different application scenarios, the mobile terminal can collect the temperature value of the screen module through the first temperature sensor, collect the temperature value of the heating device through the second temperature sensor, and obtain the temperature values ​​of m outer surface positions of the mobile terminal collected by m third temperature sensors. Then, the above formula can be fitted according to the temperature value of the screen module, the temperature value of the heating device and the temperature value of m outer surface positions of the mobile terminal in different scenarios, and a can be obtained. 11 、b 11 , 、b n1 , const1, …, a 1m 、b 1m , 、b nm 、const m, which can then be stored for subsequent calls.

[0087] When using formula (1), the mobile terminal can perform weighted summation of the temperature value of the screen module and the temperature values ​​of the multiple heating devices according to the preset weighting coefficients of the screen module and the multiple heating devices to obtain the temperature value of the outer surface of the mobile terminal, that is, the temperature value of the outer surface of the mobile terminal is determined using formula 1 according to the preset weighting coefficients of the screen module and the multiple heating devices, the temperature value of the screen module and the temperature values ​​of the multiple heating devices.

[0088] When using Formula 2, the mobile terminal can also obtain the value of the constant term, and can perform weighted summation on the temperature value of the screen module and the temperature values ​​of the multiple heating devices according to the preset weighting coefficients of the screen module and the multiple heating devices, and can determine the sum of the weighted summation result and the value of the constant term to obtain the temperature value of the outer surface of the mobile terminal, that is, the temperature value of the outer surface of the mobile terminal can be determined using Formula 2 according to the preset weighting coefficients of the screen module and the multiple heating devices, the temperature value of the screen module and the temperature values ​​of the multiple heating devices, and the value of the constant term.

[0089] In some embodiments, the preset weighting coefficient of the screen module is greater than the preset weighting coefficients of the plurality of heating devices.

[0090] Since the first temperature sensor is close to the outer surface of the mobile terminal, the temperature value of the screen module collected by the first temperature sensor is highly correlated with the actual temperature value of the outer surface of the mobile terminal. In order to reflect the correlation between the temperature value of the screen module and the temperature value of the outer surface of the mobile terminal, the preset weighting coefficient of the screen module can be greater than the preset weighting coefficients of multiple heating devices, that is, the preset weighting coefficient of the screen module is greater than the preset weighting coefficient of each heating device.

[0091] In the application scenarios of the mobile terminal, when there is a large gap between the determination scenarios of the preset weighting coefficients of the screen module and the heating device, no matter how high the temperature of the heating device is, since the preset weighting coefficient of the heating device is small, it will not cause a large deviation in the determined temperature value of the outer surface of the mobile terminal, thereby improving the precision and accuracy of the temperature value of the outer surface of the mobile terminal determined in different scenarios.

[0092] For example, in a weak network scenario, the PA device has a large power consumption and a high temperature. Since the preset weighting coefficient of the PA device is small, it will not cause a large deviation in the determined temperature value of the outer surface of the mobile terminal.

[0093] In addition, when external factors suddenly interfere with the temperature of the outer surface of the mobile terminal, since the distance between the first temperature sensor and the outer surface of the mobile terminal is relatively close, the thermal resistance between the outer surface of the mobile terminal and the first temperature sensor is relatively small, and therefore, the first temperature sensor can quickly capture the change in the temperature of the outer surface of the mobile terminal. Since the preset weighting coefficient of the screen module is relatively large, the determined temperature value of the outer surface of the mobile terminal can more accurately reflect the actual temperature value of the outer surface, and can improve the accuracy and precision of the determined temperature value of the outer surface of the mobile terminal.

[0094] In some embodiments, the mobile terminal can determine the temperature values ​​of different outer surface positions of the mobile terminal based on the temperature values ​​of the screen module and the temperature value of the heating device, and can determine the temperature value of the outer surface of the mobile terminal based on the temperature values ​​of different outer surface positions of the mobile terminal.

[0095] The range of the outer surface of the mobile terminal is relatively large. If only the temperature value of one position on the outer surface of the mobile terminal is determined as the temperature value of the outer surface of the mobile terminal, the accuracy and precision of the determined temperature value of the outer surface of the mobile terminal are low.

[0096] Therefore, in order to improve the accuracy and precision of the temperature value of the outer surface of the mobile terminal, the temperature values ​​of different outer surface positions of the mobile terminal can be determined based on the temperature value of the screen module and the temperature value of the heating device, and then the temperature value of the outer surface of the mobile terminal can be determined based on the temperature values ​​of different outer surface positions of the mobile terminal.

[0097] The mobile terminal can obtain the preset weighting coefficients of the screen module and the heating device corresponding to different outer surface positions of the mobile terminal, and then can perform weighted summation on the temperature value of the screen module and the temperature value of the heating device according to the preset weighting coefficients corresponding to different outer surface positions to obtain the temperature values ​​of different outer surface positions of the mobile terminal.

[0098] The mobile terminal may select the minimum temperature value, i.e., the minimum temperature value, from the temperature values ​​at different outer surface locations of the mobile terminal, and may determine the temperature value of the outer surface of the mobile terminal as the minimum temperature value. The mobile terminal may also select the maximum temperature value, i.e., the maximum temperature value, from the temperature values ​​at different outer surface locations of the mobile terminal, and may determine the temperature value of the outer surface of the mobile terminal as the maximum temperature value. The mobile terminal may also determine the average value of the temperature values ​​at different outer surface locations of the mobile terminal to obtain the average temperature value, and may determine the temperature value of the outer surface of the mobile terminal as the average temperature value. The mobile terminal may also determine the weighted sum of the temperature values ​​at different outer surface locations of the mobile terminal to obtain the weighted temperature value, and may determine the temperature value of the outer surface of the mobile terminal as the weighted temperature value.

[0099] These different outer surface positions of the mobile terminal may be all located on the outer surface of the screen module, or may be partially located on the outer surface of the screen module.

[0100] Since the different outer surface positions of the mobile terminal are predetermined positions, the temperature values ​​of the different outer surface positions of the mobile terminal can be quickly and accurately determined according to the preset weighting coefficients corresponding to the different outer surface positions, and then the temperature value of the outer surface of the mobile terminal can be quickly and accurately determined, which can improve the accuracy of the temperature value of the outer surface of the mobile terminal.

[0101] The different outer surface positions of the mobile terminal are the locations where the above-mentioned multiple third temperature sensors are set, that is, corresponding to the situation of the above-mentioned multiple third temperature sensors.

[0102] Figure 6 is a flow chart of another temperature determination method provided in an embodiment of the present application. The temperature determination method can be applied to a mobile terminal. For a detailed description of the mobile terminal, please refer to the above related description. Figure 6 As shown, the temperature determination method may include the following steps.

[0103] 601. Collect the temperature value of the screen module through a first temperature sensor.

[0104] 602. Collect the temperature value of the heating device through a second temperature sensor.

[0105] 603. Determine the temperature value of the outer surface of the mobile terminal according to the temperature value of the screen module and the temperature value of the heating device.

[0106] Step 601 to step 603 are the same as step 101 to step 103, and for detailed description, please refer to the above related description.

[0107] 604. When the temperature value of the outer surface of the mobile terminal is greater than or equal to the temperature threshold, control the operating state of the mobile terminal to reduce the temperature value of the outer surface of the mobile terminal.

[0108] After the mobile terminal determines the temperature value of the outer surface of the mobile terminal, it can determine whether the temperature value of the outer surface of the mobile terminal is greater than or equal to the temperature threshold. If the temperature value of the outer surface of the mobile terminal is greater than or equal to the temperature threshold, it indicates that the temperature value of the outer surface of the mobile terminal is large, and the operating state of the mobile terminal can be controlled to reduce the temperature value of the outer surface of the mobile terminal. Exemplarily, the mobile terminal can stop the operation of unnecessary processes or stop the operation of unnecessary applications.

[0109] When the temperature value of the outer surface of the mobile terminal is less than the temperature threshold, it indicates that the temperature value of the outer surface of the mobile terminal is small, and step 601 to step 602 may be continued, that is, the temperature value of the outer surface of the mobile terminal may be continued to be monitored.

[0110] It can be seen that when the temperature value of the outer surface of the mobile terminal is high, temperature control can be achieved by controlling the operating state of the mobile terminal, which can ensure that the temperature value of the outer surface of the mobile terminal is not too high, ensure the safety of the mobile terminal and improve the user experience.
