Description

Technical Field

[0001] The present application relates to the field of terminal technology, and in particular to a temperature control method and related equipment. Background Art

[0002] With the development of mobile Internet, electronic devices are becoming more and more powerful, and more and more people are using electronic devices in their work and life. During the operation of electronic devices, the over-high temperature of electronic devices may cause burns to the human body and affect the safety of users when using the devices. Therefore, there is a need for temperature control during the use of electronic devices. Summary of the invention

[0003] In order to overcome the problems existing in the related art, the present application provides a temperature control method and related equipment.

[0005] By adopting the above technical solution, since the device temperature perceived by the user when using protective accessories is different from the device temperature perceived by the user when not using protective accessories, the electronic device dynamically switches the thermal control strategy based on whether the protective accessories are used, thereby achieving the maximum satisfaction of the user's device performance requirements without affecting the safety of the user during use of the device.

[0019] By adopting the above technical solution, protective shells of different materials and / or thicknesses may have different effects on the hot spot temperature on the surface of the outer shell and the thermal insulation effect.

[0031] By adopting the above technical solution, the electronic device can reuse the existing wireless charging module and accurately identify whether a protective case is provided on the outer shell without the need for additional hardware configuration.

[0032] In one possible implementation, the temperature control method also includes: in response to a second touch operation on the display screen, obtaining a signal amount of the second touch operation, the second touch operation being an operation in which the user holds the electronic device with his hand and touches the display screen; based on the signal amount of the second touch operation, determining whether a protective shell is provided on the outer shell.

[0033] By adopting the above technical solution, the electronic device can accurately identify whether a protective case is provided on the casing based on the antenna feeding ground of the frame or the metal casing, without the need for additional hardware configuration.

[0043] By adopting the above technical solution, since the device temperature perceived by the user when using the protective accessories is lower than the device temperature perceived by the user when not using the protective accessories, when using the protective accessories, the maximum value of the device surface temperature can be allowed to be greater than the safety temperature. In this case, due to the presence of the protective accessories, the temperature of the surface of the protective accessories is lower than the safety temperature, which will not affect the safety of the user when using the device, and can meet the user's device performance requirements to the greatest extent.

[0044] In a possible implementation, when the electronic device uses a protective accessory, the difference between the maximum value of the surface temperature of the electronic device and the safety temperature is greater than a preset value.

[0047] By adopting the above technical solution, since the device temperature perceived by the user when using protective accessories is lower than the device temperature perceived by the user when not using protective accessories, when using protective accessories, the device can be allowed to work using relatively relaxed working parameters and performance release is relaxed, while when not using protective accessories, the device uses relatively tightened working parameters and performance release is tightened, so that in the same scenario, the performance of the device using protective accessories is higher than that of the device not using protective accessories, thereby satisfying the user's device performance requirements to the greatest extent.

[0048] In a possible implementation, in the second preset scenario, a difference between a maximum value of the surface temperature of the electronic device when the protective accessory is used and a maximum value of the surface temperature of the electronic device when the protective accessory is not used is greater than a preset value.

[0049] By adopting the above technical solution, when using protective accessories, the maximum surface temperature of the electronic device can be significantly greater than the maximum surface temperature when not using protective accessories. Based on the thermal insulation of the protective accessories, it will not affect the safety of the user when using the device, and can meet the user's equipment performance requirements to the greatest extent.

DETAILED DESCRIPTION

[0055] The following will describe the technical solutions in the embodiments of the present application in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0056] In the following, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present application, words such as "exemplary", "or", "for example" are used to indicate examples, illustrations or explanations.

Specifically, the use of words such as "exemplary", "or", "for example" is intended to present related concepts in a concrete way.

[0057] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by technicians in the technical field of the present application. The terms used in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application. It should be understood that, unless otherwise specified in the present application, " / " means or. For example, A / B can represent A or B. "And / or" in the present application is only a kind of association relationship describing associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. "At least one" means one or more. "Multiple" means two or more than two.

It should be understood that the order of the steps shown in the flowchart of this article can be changed, and some can also be omitted.

[0058] When users use electronic devices, the temperature of the electronic devices may rise. Excessive temperature will not only easily lead to excessive power consumption of the device, damage the hardware and corresponding functions of the device, but also may affect the safety of the user when using the device. For example, for portable electronic devices, in order to prevent users from getting burned by touching the parts of the electronic device (screen / casing, etc.), the surface temperature of the electronic device must be lower than the safety temperature based on the 3C safety certification standard (for example, the safety temperature of portable devices such as mobile phones and tablets is 48°C).

[0059] In order to solve the above problems, a thermal control strategy is generally configured in the electronic device. According to the temperature of the electronic device, the performance of the device is limited based on the corresponding thermal control strategy. For example, the operating frequency of the processor is reduced, the brightness of the display screen is reduced, etc., so as to achieve the purpose of reducing the temperature of the device. After purchasing an electronic device, the user may stick a protective film and / or use a protective case on the display screen for actual use needs. However, the preset thermal control strategy is a thermal control strategy set based on the bare device form of the device when it leaves the factory, which may not be consistent with the actual user usage habits. The bare device form referred to in the embodiment of the present application may refer to a form that does not include a protective film or a protective case.

[0060] In view of this, an embodiment of the present application provides a temperature control method that can be applied to electronic devices. It can dynamically switch thermal control strategies by identifying whether the electronic device uses a protective film and / or a protective case, thereby achieving the maximum satisfaction of the user's device performance requirements without affecting the safety of the user during use of the device.

[0061] The temperature of an electronic device can be detected in real time by a temperature sensor. For example, taking a mobile phone as an example, the electronic device can obtain the temperature of the display screen based on multiple temperature sensors installed on the display screen, and the multiple temperature sensors can be fitted and distributed at different positions of the display screen. For another example, the electronic device can also obtain the temperature of the shell based on multiple temperature sensors installed on the shell, and the multiple temperature sensors can be fitted and distributed at different positions of the shell, for example, the multiple temperature sensors can be fitted and distributed at different positions of the back shell area.

[0062] like Figure 1 As shown, taking the electronic device 100 as a mobile phone as an example, the hot spot distribution of the electronic device 100 during use is illustrated. The hot spot referred to in the embodiment of the present application may be a local high temperature area with a temperature higher than other areas. The determination of the hot spot can be achieved using, for example, a thermal imaging device, which can detect infrared radiation emitted by an object to generate a temperature distribution image, thereby accurately displaying the temperature hot spot on the surface of the electronic device. The temperature value of the hot spot can be obtained by directly detecting the thermal imaging device, or by fitting the sensed values ​​of multiple temperature sensors.

[0063] Assuming that four temperature sensors are used to detect the temperature of the display screen, for any candidate hotspot on the display screen (the candidate hotspot can be set as a common position of the display screen temperature hotspot), the temperature change data of the candidate hotspot and the temperature change data of the four temperature sensors can be measured and recorded, and a mathematical relationship between the temperature of the candidate hotspot and the temperature of the four temperature sensors can be constructed based on the recorded data, and then the electronic device 100 can subsequently determine the temperature of the candidate hotspot based on the mathematical relationship and the temperature values ​​sensed in real time by the four temperature sensors. Similarly, for any candidate hotspot on the housing (the candidate hotspot can be set as a common position of the housing temperature hotspot, for example, near the processor, battery, camera, etc.), a mathematical relationship between the temperature of the candidate hotspot and the temperatures of multiple temperature sensors on the housing can also be constructed based on the recorded data, and then the electronic device 100 can subsequently determine the temperature of the candidate hotspot based on the mathematical relationship and the temperature values ​​sensed in real time by the multiple temperature sensors. In the process of temperature control of the electronic device 100, the device performance can be limited by the thermal control parameters corresponding to the maximum hotspot temperature in the housing and the display screen.

[0064] In some embodiments, the use of a protective film may affect the hot spot temperature on the display screen, and the use of a protective shell may affect the hot spot temperature of the back shell. For the display screen, the temperature fitting can be performed separately with and without the protective film, and for the back shell, the temperature fitting can be performed separately with and without the protective shell.

[0065] For the electronic device 100 in the form of a bare device, if the hot spot temperature on the display screen is higher than the hot spot temperature on the outer shell, in this case, the highest hot spot temperature is located on the display screen, and the presence or absence of a protective shell generally does not affect the highest hot spot temperature of the electronic device 100, while the presence or absence of a protective film will affect the highest hot spot temperature of the electronic device 100 and / or the hot spot distribution of the display screen. Conversely, if the hot spot temperature of the outer shell is higher than the hot spot temperature on the display screen, in this case, the highest hot spot temperature is located on the outer shell, and the presence or absence of a protective shell will affect the highest hot spot temperature of the electronic device 100 and / or the hot spot distribution of the outer shell, while the presence or absence of a protective film generally does not affect the highest hot spot temperature of the electronic device 100.

[0066] For the electronic device 100 in the form of a bare device, the use of a protective case can reduce the surface temperature of the outer shell in contact with the human body, and the use of a protective film can reduce the surface temperature of the display screen in contact with the human body.

[0067] like Figure 1 As shown in (a) of FIG. 1 , it is shown that during the use of the electronic device 100 in the form of a bare device, the hot spots on the display screen include hot spots 101 and 102. Figure 1 As shown in (b) in the figure, it is illustrated that during the use of the electronic device 100, the hot spots on the display screen with the protective film include the hot spots 103.

[0068] like Figure 1 As shown in (c) of FIG. 1 , it is shown that during the use of the electronic device 100 in the form of a bare device, the hot spots on the back cover include hot spots 104, 105 and 106. Figure 1 As shown in (d) in the figure, it is shown that during the use of the electronic device 100, the hot spots on the back cover of the protective cover include hot spots 107 and hot spots 108.

[0069] In some embodiments, by measuring the case temperature of the electronic device 100 with and without a protective case, a case temperature reduction benefit (reduction value of the case hot spot with a protective case compared to without a protective case) as shown in Table 1 below is obtained.

[0070] It can be seen from Table 1 above that after using the protective case, the surface temperature of the shell in contact with the human body will be reduced. That is, when the electronic device 100 is in the same operating state, the shell temperature perceived by the user when using the protective case is lower than the shell temperature perceived by the user when not using the protective case. That is, when using the protective case, the electronic device 100 can be subject to smaller performance restrictions to meet the user's device performance requirements to the greatest extent, while when not using the protective case, the electronic device 100 can be subject to greater performance restrictions in order to ensure the safety of the user when using the device.

[0071] In some embodiments, the use of a protective film and a protective case have a certain mutual influence on the hot spot temperature benefit of the whole device, as shown in Table 2 below, which illustrates the hot spot temperature reduction benefit under different usage scenarios (compared with the hot spot temperature reduction value of the whole device in the bare device form, the hot spot of the whole device can be the hot spot with the maximum temperature in the housing and the display screen). The electronic device 100 can pre-store multiple thermal control strategies to cope with different usage scenarios.

[0072] It can be seen from Table 2 above that the surface temperature of the electronic device 100 in contact with the human body will be reduced after using a protective case and / or a protective film. That is, when the electronic device 100 is in the same operating state, the temperature of the entire device perceived by the user when using a protective case and / or a protective film is lower than the temperature of the entire device perceived by the user when the device is in a bare form. That is, in the case of using a protective case and / or a protective film, the performance of the electronic device 100 can be relatively slightly restricted to meet the user's device performance requirements to the greatest extent, while in the case of a bare device form, in order to ensure the safety of the user when using the device, the performance of the electronic device 100 can be relatively greatly restricted.

[0073] Figure 2 A possible thermal control strategy for electronic devices is shown.

[0074] The thermal control strategy may refer to a strategy for limiting the performance of functional modules in the electronic device 100 according to the hotspot temperature, including but not limited to regulating the CPU / GPU / NPU / DDR memory frequency, display frame rate / refresh rate / brightness, RF antenna power, audio tone / loudness, camera performance, charging power, etc.

[0075] like Figure 2 As shown, as the hotspot temperature increases, the performance of the electronic device 100 can be gradually restricted: screen brightness is reduced, refresh rate is reduced, CPU / GPU frequency is limited, camera frame rate is reduced, beauty algorithms are turned off, cellular network is switched from 5G to 4G, game frame rate is reduced, background downloads are paused, network speed is limited, flash is turned off, hotspot is turned off, etc., high temperature pop-up windows appear, and the computer is shut down.

[0076] In order to achieve more accurate temperature control of the electronic device 100 , the electronic device 100 involved in the embodiment of the present application needs to have the ability to identify the protective film and / or the protective case.

[0077] The identification of the protective film and the identification of the protective case will be described separately below.

[0078] Identification of protective film: The material of the protective film used in electronic devices is generally a polymer material (PET, TPU material, etc.) or a composite material (tempered glass, etc.). The thermal conductivity of the materials does not differ much, but the protective film may have different thicknesses, and the thermal conductivity of protective films of different thicknesses has certain differences. Therefore, different thermal control strategies can be set based on the different thicknesses of the protective film. The thermal control strategy can be composed of multiple thermal control temperatures and thermal control parameters corresponding to each thermal control temperature. Different thermal control strategies may refer to different thermal control parameters or different thermal control parameter values. If the thickness of the protective film cannot be identified, different thermal control strategies can be set based on whether there is a protective film. For example, the presence of a protective film corresponds to one thermal control strategy, and the absence of a protective film corresponds to another thermal control strategy.

[0079] For capacitive touch screens, there is the following mathematical relationship: C=εS / d, where C is the capacitance of the capacitor, S is the area facing the two plates of the capacitor, d is the distance between the two plates of the capacitor, and ε is the dielectric constant of the dielectric. When a finger touches the screen, the dielectric at the touch point changes from air to a mixture of finger and air, that is, the value of ε changes. When a finger touches the screen, there is a certain contact or interaction area between the finger and the sensing electrode, and the value of S changes. That is, when a finger touches the screen, the dielectric constant ε and the area facing S change, causing the capacitance value C at the touch point to change, and then the position of the touch point can be determined by detecting the change in capacitance value.

[0080] Furthermore, after the protective film is attached to the display screen, the value of d increases, which in turn causes the capacitance value C to decrease. The change in the d value can be used to determine whether there is a protective film on the display screen, and the thickness of the protective film can be determined by determining the d value before and after the protective film is applied.

[0081] In the actual application of capacitive touch screens, the measurement of the capacitance value C is not convenient. Generally, the signal amount of the coupling signal is measured, and then the position of the touch point is determined based on the change in the signal amount of the coupling signal. When a finger touches the display screen, the capacitance value C at the touch point increases, the amount of stored charge increases, and the signal amount of the coupling signal also increases. There is a positive correlation between the signal amount of the coupling signal and the capacitance value C. After the protective film is attached to the display screen, the capacitance value C will become smaller, that is, the signal amount of the coupling signal will become smaller. In other words, the use of a protective film will reduce the signal amount of the coupling signal.

[0082] like Figure 3As shown in the figure, it is shown that the signal amount of the coupling signal before the display screen uses the protective film is greater than the signal amount of the coupling signal after the protective film is used. For example, the signal amount of the coupling signal of the touch operation of a certain electronic device before the protective film is used is 3000, and the signal amount of the coupling signal of the touch operation after the protective film is used is 1600.

[0083] In some embodiments, an elastic wave sensor can be configured on the display screen to determine whether there is a protective film on the display screen and the thickness of the protective film. For example, the elastic wave sensor can be set under the cover glass or the touch layer. When a finger touches the display screen, a pressure pulse is generated. This pressure pulse will propagate in the medium in the form of an elastic wave, and the elastic wave sensor can sense the propagation of this elastic wave. For display screens with and without a protective film, the values ​​sensed by the elastic wave sensor are different, and for display screens with protective films of different thicknesses, the values ​​sensed by the elastic wave sensor will also be different. Therefore, based on the data sensed by the elastic wave sensor, it can be determined whether there is a protective film on the display screen and the thickness of the protective film.

[0084] In some embodiments, since the electronic device obtains temperature sensing data from a temperature sensor, different temperature fitting strategies can be used for protective films of different thicknesses, so as to obtain the surface temperatures of protective films of different thicknesses based on the sensing data of the temperature sensor. This allows protective films of different thicknesses to have different corresponding temperature control strategies due to the different surface temperatures obtained by fitting under the same temperature sensing data.

[0085] Identification of protective case: The material of the protective shell used in electronic devices is generally insulating material (for example, tempered glass, silicone, plastic) or metal material (aluminum alloy, stainless steel, etc.). The thermal conductivity of insulating materials and metal materials is different to a certain extent, and the protective shell may have different thicknesses. The thermal conductivity of protective shells of different thicknesses is also different to a certain extent. Therefore, if the material of the protective shell (insulating material or metal material) can be identified, different thermal control strategies can be set based on the material of the protective shell. If the thickness of the protective shell can be identified, different thermal control strategies can be set based on the different thicknesses of the protective shell. If the material and thickness of the protective shell cannot be identified, different thermal control strategies can be set based on whether there is a protective shell.

[0086] In some embodiments, for electronic devices such as mobile phones and tablet computers, a keyboard protective case may be provided with a pogo pin. When the pogo pin is connected to the electronic device, it can be determined that the electronic device uses a keyboard protective case.

[0087] like Figure 4As shown, taking the electronic device as a tablet computer as an example, the electronic device 100 has a first connection end 1001, and the keyboard 200 has a second connection end 2001. The keyboard 200 includes a keyboard part and a protective shell part. The electronic device 100 can be fixedly connected to the keyboard 200 to keep the electronic device 100 in an inclined state at a preset tilt angle, which is convenient for users to use. The fixed connection can be, for example, adsorption by an opposite magnet or snap connection with a card slot, so that the position of the electronic device 100 relative to the keyboard 200 remains fixed. The fixed connection is a detachable connection. After the electronic device 100 and the keyboard 200 are fixedly connected, the first connection end 1001 of the electronic device 100 contacts and is electrically connected to the second connection end 2001 of the keyboard 200. The electrical connection between the first connection end 1001 and the second connection end 2001 enables the transmission of electrical signals between the electronic device 100 and the keyboard 200, such as communication or charging and discharging. The second connection end 2001 of the keyboard 200 may be a Pogopin, and the first connection end 1001 of the electronic device 100 may be a contact for connecting with the Pogopin. That is, the electronic device 100 can determine whether the keyboard protective case is connected by identifying whether the first connection end 1001 is electrically connected to the Pogopin, thereby realizing the identification of the protective case.

[0088] In some embodiments, some keyboard protective cases may also be connected to the electronic device 100 via interfaces such as Bluetooth or USB Type-C. For example, a keyboard protective case with a Bluetooth module may be connected to the electronic device 100 via Bluetooth. For another example, if a keyboard protective case or other types of protective cases are equipped with a micro pump for cooling, or a flash, or a fan, it has a large power supply demand and is generally connected to the electronic device 100 via a USB Type-C interface. That is, the electronic device 100 can also determine whether the keyboard protective case is connected through Bluetooth connection information or USB Type-C interface connection information, thereby realizing the identification of the protective case.

[0089] In some embodiments, the keyboard protective shell or other types of protective shells may also be configured with a Hall sensor, and the Hall sensor is used to implement intelligent sleep and wake-up functions. For example, when the user closes the protective shell, the Hall sensor in the protective shell will sense the change in the magnetic field and send a signal to the electronic device 100. After receiving the signal, the electronic device 100 automatically enters a sleep state. When the user opens the protective shell, the Hall sensor detects the change in the magnetic field again and sends a signal to the electronic device 100. The electronic device 100 automatically wakes up and enters a normal working state. In this case, the identification of the protective shell can be achieved by multiplexing the Hall sensor. If the electronic device 100 is in contact with a protective shell with a Hall sensor, the Hall sensor can sense the change in the magnetic field and send a sensing signal to the electronic device 100. The sensing signal of the Hall sensor is used to determine whether the protective shell is used. For example, in the case where the sensing signal of the Hall sensor is not received, it can be considered that the protective shell is not used. In the case where the sensing signal of the Hall sensor can be continuously received, it can be considered that the protective shell is used.

[0090] For a magnetic protective case, a Hall sensor may also be provided in the electronic device 100, and the electronic device 100 may also determine whether a protective case is used based on magnetic field change data of the Hall sensor.

[0091] In some embodiments, for an electronic device 100 supporting a wireless charging function, the wireless charging coil is generally placed on the back shell of the electronic device. There will be differences in wireless transmission power and quality factor (Q value) when using a protective shell and when not using a protective shell. For example, if the electronic device 100 with a protective shell is placed on a wireless charging pad, due to the certain thickness of the protective shell, the distance between the transmitting coil on the wireless charging pad and the receiving coil on the electronic device increases compared to the case where the back shell is directly in contact with the wireless charging pad. The magnetic field strength generated by the transmitting coil will decay as the distance increases, the magnetic field strength received by the receiving coil will weaken, and the induced electromotive force generated in the receiving coil will also decrease, resulting in a decrease in transmission power. The increase in distance will also result in a decrease in the number of magnetic lines of force generated by the transmitting coil that can pass through the receiving coil, that is, a decrease in magnetic flux coupling, and a decrease in magnetic flux coupling will result in a decrease in the power transmitted to the receiving end. Similarly, an increase in distance will increase the energy loss of the magnetic field during transmission, resulting in a decrease in the Q value. The increase in distance will also reduce the mutual inductance between the transmitting coil and the receiving coil, resulting in a decrease in the Q value. That is, it is possible to determine whether a protective shell is used by detecting the transmission power and the Q value.

[0092] In some embodiments, whether a protective case is used can also be identified by the way that the signal strength of the touch panel (TP) is affected by holding the electronic device 100 by hand. For example, for a protective case made of insulating material, if the electronic device 100 is a metal back shell device, when the protective case is not used, the hand holds the electronic device 100 and the finger touches the TP, the TP, the hand and the metal back shell form a loop, and the signal amount generated by the finger touching the TP is the first signal amount. When the protective case is used, the hand holds the electronic device 100 and the finger touches the TP. Since the metal back shell is covered by the protective case, the hand does not touch the metal back shell and a loop cannot be formed. The signal amount generated by the finger touching the TP is the second signal amount. The first signal amount and the second signal amount have a large difference, which can be used to identify whether a protective case is used.

[0093] For example, Figure 5 As shown, there is an antenna feed ground 1002 in the middle frame of the electronic device 100. For a protective shell of insulating material, if the electronic device 100 is a non-metal rear shell device, when the protective shell is not used, the hand holds the electronic device 100 and the finger touches TP. Since the antenna feed ground 1002 is generally located in the lower area of ​​the middle frame, the hand will most likely contact the antenna feed ground 1002 when holding the electronic device 100. TP, the hand and the antenna feed ground 1002 form a loop. The signal amount generated by the finger touching the TP is the third signal amount. When the protective shell is used, the hand holds the electronic device 100 and the finger touches the TP. Since the antenna feed ground 1002 will be covered by the protective shell, the hand does not touch the antenna feed ground 1002 and a loop cannot be formed. The signal amount generated by the finger touching the TP is the fourth signal amount. The third signal amount and the fourth signal amount have a large difference, which can be used to identify whether the protective shell is used.

[0094] In some embodiments, a light sensor can also be used to identify whether a protective case is used. For example, a light sensor (a light sensor for proximity light, ambient light, or color temperature sensing) can be installed at a certain position in the middle frame, back shell, or rear camera area of ​​the electronic device 100. The protective case can be identified by identifying whether the light sensor is blocked, combining the blocking time and the screen-on time of the electronic device. Specifically, when the electronic device 100 is in the screen-on stage and the light sensor is continuously blocked, it can be considered that the electronic device 100 is using a protective case. When the electronic device 100 is in the screen-off stage and the light sensor is continuously blocked, it may be that the electronic device 100 is placed in a pocket. When the electronic device 100 is in the screen-on stage and the light sensor is not blocked, it can be considered that the electronic device is not using a protective case.

[0095] In some embodiments, a capacitive proximity sensor can also be used to identify whether a protective case is used. For example, a capacitive proximity sensor can be installed at the corner of the middle frame of the electronic device 100. For the capacitive proximity sensor, there is also the following mathematical relationship: C=εS / d. Using a protective case or not using a protective case will change the value of the parameter d, and then when the hand holds the electronic device 100, it can be based on the capacitance value C sensed by the capacitive proximity sensor to identify whether a protective case is used.

[0096] like Figure 6 As shown in (a) of FIG. 1 , the capacitive proximity sensor 1003 is disposed at a corner of the middle frame 1004 of the electronic device 100. Figure 6 As shown in (b), the capacitive proximity sensor 1003 is located below the middle frame 1004, and there is a certain gap between the middle frame 1004 and the capacitive proximity sensor 1003, which can prevent the middle frame 1004 from continuously contacting the capacitive proximity sensor 1003 and protect the capacitive proximity sensor 1003. When the protective case is not used, when the finger or palm holds the middle frame 1004, the finger or palm contacts the capacitive proximity sensor 1003 through the middle frame 1004. Figure 6 As shown in (c), when a protective case is used, the finger or palm holds the protective case, and the finger or palm contacts the capacitive proximity sensor 1003 through the protective case and the middle frame 1004, and the amount of signal that the capacitive proximity sensor 1003 can detect is significantly different from that when the protective case is not used. For example, when the protective case is not used, the amount of signal that the capacitive proximity sensor 1003 can detect is 13000, and when the protective case is used, the amount of signal that the capacitive proximity sensor 1003 can detect is 6000.

[0097] In some embodiments, it is also possible to identify whether a protective case is used by the amount of vibration after the electronic device 100 is vibrated. For example, the electronic device 100 is generally equipped with an accelerometer and a gyroscope, and the amount of vibration can be sensed by the accelerometer and the gyroscope. Taking the electronic device 100 as a mobile phone as an example, the weight of a mobile phone is generally 180g-240g, and the weight of a protective case is generally 10g-20g. Using a protective case and not using a protective case will result in a certain difference in the weight of the device. When the mobile phone motor vibrates, there is a certain difference in the amount of vibration detected by the accelerometer and the gyroscope, based on which it is possible to identify whether a protective case is used.

[0098] For example, when a user connects a charger to charge the electronic device 100, the electronic device 100 will generally vibrate, which can trigger the identification of whether a protective case is used. For another example, when the alarm of the electronic device 100 vibrates, or a call vibrates, or a message reminder vibrates, it can also trigger the identification of whether a protective case is used.

[0099] In some embodiments, it is also possible to identify whether a protective case is used by the temperature difference inside or on the surface of the electronic device 100. Generally speaking, the use of a protective case will increase the temperature inside the device, and the temperature difference between the cold area and the hot area of ​​the device will be further expanded, thereby identifying whether a protective case is used. Figure 7 As shown in the figure, taking the charging scenario as an example, under the same charging current, the temperature difference between the cold and hot areas of the case is different from that of the case without the case. The hot area can refer to the charging circuit module, and the cold area can be the USB board, or the audio processing module (when charging without playing audio), etc.

[0100] like Figure 7 As shown in (a), it is a schematic diagram of the charging current and temperature difference (temperature difference between the cold zone and the hot zone) changing with time when the electronic device 100 is charged without using a protective case. Curve S1 is the temperature difference between the cold zone and the hot zone, and curve S2 is the charging current. Figure 7 As shown in (b), it is a schematic diagram of the charging current and the temperature difference (the temperature difference between the cold zone and the hot zone) changing with time when the electronic device 100 is charged in the state of using the protective case. Curve S3 is the temperature difference between the cold zone and the hot zone, and curve S4 is the charging current. Figure 7 From (a) and (b), we can see that under the same charging current (3500mA), without a protective case, the temperature difference between the cold zone and the hot zone is about 3.5°C, and with a protective case, the temperature difference between the cold zone and the hot zone is about 4°C. Figure 7 The ordinates of (a) and (b) are dimensionless coordinates used to indicate both the charging current and the temperature difference, with 1°C corresponding to 1000 on the ordinate scale.

[0101] In some embodiments, an elastic wave sensor can be configured on the outer shell to determine whether there is a protective shell and the thickness of the protective shell. For example, the elastic wave sensor can be set in a position area such as the middle frame or the back shell. When the electronic device 100 is held by the hand, a pressure pulse is generated. This pressure pulse will propagate in the medium in the form of an elastic wave, and the elastic wave sensor can sense the propagation of this elastic wave. For electronic devices 100 with a protective shell and without a protective shell, the values ​​sensed by the elastic wave sensor are different, and for protective shells with different thicknesses, the values ​​sensed by the elastic wave sensor will also be different. Therefore, based on the data sensed by the elastic wave sensor, it can be determined whether the electronic device 100 uses a protective shell and the thickness of the protective shell.

[0102] In some embodiments, the above-mentioned two methods of identifying the protective shell can also be combined to determine the material of the protective shell. For example, based on the Pogopin or Hall sensor, it is determined that the electronic device 100 uses a protective shell, and then the material of the protective shell is identified based on the way the hand holding the electronic device 100 affects the signal strength of the touch screen. For a protective shell made of insulating material and a protective shell made of metal, the degree to which the hand holding the electronic device 100 affects the signal strength of the touch screen is different. For a protective shell made of insulating material, the hand holding the electronic device 100 and the finger touching the TP cannot form a loop. For a protective shell made of metal, the TP, the hand and the protective shell form a loop.

[0103] In some embodiments, since the electronic device acquires the temperature sensing data of the temperature sensor, different temperature fitting strategies can be used for protective shells of different thicknesses, so as to fit the surface temperatures of protective shells of different thicknesses based on the sensing data of the temperature sensor, so that under the same temperature sensing data, protective shells of different thicknesses may correspond to different temperature control strategies due to different fitted surface temperatures. Similarly, different temperature fitting strategies can be used for protective shells of different materials, so as to fit the surface temperatures of protective shells of different materials based on the sensing data of the temperature sensor, so that under the same temperature sensing data, protective shells of different materials may correspond to different temperature control strategies due to different fitted surface temperatures.

[0104] In order to more clearly understand the implementation details of the above temperature control method on electronic equipment, Figures 8 to 14 Let's introduce the process of various software and hardware components in electronic equipment to achieve the above temperature control method. The details are as follows: The operating system of the electronic device may adopt a layered architecture, an event-driven architecture, a micro-kernel architecture, a micro-service architecture, or a cloud architecture. The present application embodiment takes the Android system of the layered architecture as an example to illustrate the software structure of the electronic device. Figure 8As shown, the layered architecture divides the software into several layers, each with clear roles and division of labor. The layers communicate with each other through software interfaces. Taking the Android system as an example, in some embodiments, the Android system is divided into four layers, from top to bottom, namely, the application layer (Apk), the application framework layer (Framework), the hardware abstraction layer (HAL) and the kernel layer (Kernel).

[0105] The application layer may include a series of application packages. For example, the application package may include instant messaging applications, video applications, setting applications, and other applications. The instant messaging application may be an application that supports instant messaging and / or instant calling, and the video application may be an application that supports video / short video playback. The setting application may be an application that performs system configuration, device management, application management, and personalization.

[0106] The application framework layer may include an input system, a window manager, a content provider, a view system, a resource manager, and the like. The input system is used to process input events. The window manager is used to manage window programs. The window manager can obtain the size of the display screen, determine whether there is a status bar, lock the screen, and the like. The content provider is used to store and obtain data and make the data accessible to the application. The data may include videos, images, and the like. The view system includes visual controls, such as controls for displaying text, controls for displaying pictures, and the like. The view system can be used to build applications. The display interface may consist of one or more views. The resource manager provides various resources for the application, such as localized strings, icons, images, layout files, video files, and the like.

[0107] The hardware abstraction layer is an interface layer between the operating system kernel and the hardware circuit. The HAL layer includes, but is not limited to, accessory identification services and thermal control strategy setting services. In an embodiment of the present application, the accessory mode recognition service can be used to identify whether an electronic device uses protective accessories (for example, protective accessories include but are not limited to protective cases and protective films) under the call of a preset service, or to trigger the identification of whether an electronic device uses protective accessories under a preset state, or to identify whether an electronic device uses protective accessories every preset time. The preset service can be set according to actual identification requirements, and the preset service can be a system service or an application service, which is not limited in the embodiment of the present application.

[0108] For example, the device can be set to trigger the identification of whether a protective accessory is used on the electronic device in a vibration state or in a screen-on unlock state.

[0109] The thermal control strategy setting service can be used to set different thermal control strategies according to the identification result of the accessory identification service. For example, the thermal control strategy setting service can set the corresponding thermal control strategy according to the identification result of the accessory identification service and the current highest hot spot temperature.

[0110] In some embodiments, the accessory identification service may determine whether the electronic device uses a protective accessory based on an intelligent identification method. The intelligent identification method may refer to determining whether the electronic device uses a protective accessory based on detection data of a sensor.

[0111] In some embodiments, the accessory recognition service can also be performed based on artificial intelligence technology to improve the accuracy of accessory recognition. For example, the electronic device pre-deploys an accessory recognition model, or a large model with accessory recognition capabilities. In the accessory recognition process, the model determines whether the electronic device uses protective accessories based on the detection data of the sensor, and in the case of using protective accessories, further determines whether it is a protective shell or a protective film, the material and / or thickness of the protective shell, the thickness of the protective film, etc. The training samples of the model may include multiple sample subsets, for example, a sensor detection data set without using a protective film and a protective shell, a sensor detection data set using only a protective film (which may include a protective film of multiple thicknesses), a sensor detection data set using only a protective shell (which may include a protective shell of multiple thicknesses, and may also include a protective shell of insulating material and metal material), and a sensor detection data set using a protective film and a protective shell (which may include a protective film and a protective shell of multiple thicknesses, and may also include a protective shell of insulating material and metal material). The training method of the model may be a training method recorded in the relevant technology, and the examples of this application are not limited to this.

[0112] In some embodiments, the surface temperature fitting can also be performed based on artificial intelligence technology. For example, the surface temperature fitting training can be performed based on sensor detection data and surface thermal imaging data of different protective films and / or protective shells, so that the model has the ability to fit the surface temperature of the protective film and / or protective shell.

[0113] In some embodiments, the accessory identification service may also obtain the protection accessory information set by the user. For example, the user may set the protection accessory currently used by the electronic device through the settings application or the control center. In order to avoid conflicts between the intelligent identification method and the user settings, the priority of the protection accessory information set by the user may be higher than the priority of the protection accessory information obtained by the intelligent identification.

[0114] The kernel layer may include drivers associated with the hardware of the hardware layer. The kernel layer may also include programs closely related to the hardware, such as interrupt handlers, and may also include basic, common, and high-frequency modules, such as clock management modules and process scheduling modules.

[0115] For example, the hardware layer includes display screens and sensors (accelerometers, touch sensors, gyroscopes, etc.). The kernel layer may include display drivers, touch drivers, and sensor drivers. Display drivers are used to drive the display panel in the display screen to display content. Touch drivers are used to obtain user touch operations on the display screen from the touch layer in the display screen. Sensor drivers are used to drive sensors for sensing.

[0116] Please also see Fig. 9 , is a flow chart of a temperature control method provided in an embodiment of the present application. The method is described by taking the identification of whether a protective film is used on a display screen as an example.

[0117] 901: The electronic device identifies whether a protective film is used on the display screen in response to a preset trigger condition.

[0118] In some embodiments, the preset trigger condition may refer to a condition that triggers the electronic device to identify whether a protective film is used on the display screen. The preset trigger condition may be set according to actual needs, and the embodiments of the present application are not limited to this. For example, the preset trigger condition may be the call of a preset service, or the device is in a preset state, or at preset intervals.

[0119] For example, the preset trigger conditions include, but are not limited to, opening an application with high power consumption, the device temperature being greater than a certain threshold, performing identification once every preset time in the charging state, etc.

[0120] In some embodiments, whether a protective film is used on the display screen can be identified by the above-mentioned method for identifying the protective film, which will not be described in detail here.

[0121] 902: If it is determined that no protective film is used on the display screen, the electronic device uses a default thermal control strategy to control the temperature.

[0122] In some embodiments, the default thermal control strategy can be set according to the needs, and the embodiments of the present application are not limited to this. For example, the default thermal control strategy can be a thermal control strategy recorded in the relevant technology, so as to limit the performance of the functional modules in the electronic device according to the hot spot temperature, so as to avoid the hot spot temperature being too high and affecting the safety of the user using the device. The hot spot temperature can be the larger of the hot spot temperature on the display surface and the hot spot temperature on the shell surface.

[0123] 903: If it is determined that a protective film is used on the display screen, the electronic device obtains the thickness of the protective film.

[0124] In some embodiments, the thickness of the protective film can be obtained by using the above-mentioned identification method of the thickness of the protective film, which will not be described in detail here.

[0125] 904: The electronic device performs temperature control using a thermal control strategy corresponding to the thickness of the protective film.

[0126] In some embodiments, protective films of different thicknesses may correspond to different thermal control strategies to achieve more accurate temperature control of electronic devices, and to meet the user's device performance requirements to the greatest extent without affecting the safety of the user in the process of using the device. Assuming that as the thickness of the protective film increases, the ability to isolate the hot spot temperature of the display screen becomes stronger, and the temperature of the display screen perceived by the user is relatively lower, the electronic device can use a relatively weak performance limitation strategy to meet the user's device performance requirements to the greatest extent, and avoid the impact of excessive hot spot temperature on the user's device safety.

[0127] In some embodiments, the electronic device may also set protective films of all thicknesses to share a common thermal control strategy, ie, the thickness of the protective film is not identified or differentiated.

[0128] like Fig.10 As shown in (a) and (b) in FIG. 1 , it is assumed that the highest hot spot temperature on the display surface is 46°C and the highest hot spot temperature on the protective film surface is 43°C. Assuming that the highest temperature hot spot is located on the display screen, for Fig.10 For (a), no protective film is used on the display screen, and the electronic device uses a thermal control strategy corresponding to 46°C for temperature control. Fig.10 As for (b) in the figure, the electronic device adopts the thermal control strategy corresponding to 43℃ for temperature control, which can achieve greater performance release than the thermal control strategy corresponding to 46℃.

[0129] As shown in Table 3 below, a possible thermal control strategy is illustrated, and the thermal control strategy includes thermal control parameters corresponding to multiple hot spot temperatures.

[0130] In some embodiments, it can also be set that when the highest hot spot temperature on the surface is lower than a certain temperature value, no restriction is imposed on the performance of the device.

[0131] In some embodiments, taking the safety temperature of the device surface temperature as 48°C as an example, assuming that the highest temperature hotspot is located on the display screen, when the protective film is not used, the highest hotspot temperature on the display screen surface is 48°C. When the temperature approaches 48°C, stricter performance restrictions are required to prevent the hotspot temperature on the display screen surface from exceeding 48°C. When a protective film is used, the highest hotspot temperature on the protective film surface is 48°C, and performance restrictions are made based on the hotspot temperature on the protective film surface. In this case, if the highest hotspot temperature on the protective film surface is 48°C, assuming that the highest hotspot temperature on the display screen surface is 52°C, compared to when the protective film is not used, when the hotspot temperature on the display screen surface approaches 48°C, the device performance is released more, resulting in the hotspot temperature on the display screen surface rising to 52°C.

[0132] In actual application scenarios, considering that there may be fitting errors in the hotspot temperature on the surface of the protective film, in order to maximize the safety of the user's device use, the maximum hotspot temperature on the surface of the protective film can be set to be slightly lower than 48°C, for example, 47°C. In this case, the maximum hotspot temperature on the surface of the display screen will still be greater than 48°C, which is more effective than the related art that strictly follows the hotspot temperature on the surface of the display screen not exceeding 48°C. The device performance is released to a greater extent. And for the related art, when a protective film is used, even if the use of the protective film will change the hotspot temperature on the surface of the display screen, the hotspot temperature on the surface of the display screen generally changes within 0~1°C relative to the case where the protective film is not used (for example, the hotspot temperature on the surface of the display screen obtained by fitting is 48°C, but due to the use of the protective film, the actual hotspot temperature on the surface of the display screen may reach 48.8°C), which cannot reach the level of releasing the device performance, resulting in the degree of allowing the hotspot temperature on the surface of the display screen to increase significantly.

[0133] Please also see Fig.11 , is a flow chart of a temperature control method provided by another embodiment of the present application. The method is described by taking the identification of whether a protective shell is used on the housing as an example.

[0134] 111: The electronic device identifies whether a protective case is used on the housing in response to a preset trigger condition.

[0135] In some embodiments, the preset trigger condition may refer to a condition that triggers the electronic device to identify whether a protective case is used on the housing. The preset trigger condition may be set according to actual needs, and the embodiments of the present application are not limited to this. For example, the preset trigger condition may be the call of a preset service, or the device is in a preset state, or at preset intervals.

[0136] For example, the preset trigger conditions include, but are not limited to, opening an application with high power consumption, the device temperature being greater than a certain threshold, performing identification once every preset time in the charging state, etc.

[0137] In some embodiments, whether a protective case is used on the housing can be identified by the above-mentioned method of identifying the protective case, which will not be described in detail here.

[0138] 112: If it is determined that no protective case is used on the housing, the electronic device uses a default thermal control strategy to control the temperature.

[0139] In some embodiments, the default thermal control strategy can be set according to the needs, and the embodiments of the present application are not limited to this. For example, the default thermal control strategy can be a thermal control strategy recorded in the relevant technology to limit the performance of the functional modules in the electronic device according to the hot spot temperature to avoid the hot spot temperature being too high and affecting the safety of the user's use of the device.

[0140] 113: If it is determined that a protective case is used on the housing, the electronic device obtains the material and / or thickness of the protective case.

[0141] In some embodiments, the material and / or thickness of the protective shell can be obtained by the above-mentioned identification method of the material or thickness of the protective shell, which will not be repeated here.

[0142] 114: The electronic device uses a thermal control strategy corresponding to the material and / or thickness of the protective shell to control temperature.

[0143] In some embodiments, protective shells of different thicknesses may correspond to different thermal control strategies, and protective shells of different materials may also correspond to different thermal control strategies, so as to achieve more accurate temperature control of electronic devices, and meet the user's device performance requirements to the greatest extent without affecting the safety of the user in the process of using the device. Assuming that as the thickness of the protective shell increases, the ability to isolate the hot spot temperature of the shell becomes stronger, and the temperature of the shell perceived by the user is relatively lower, the electronic device can use a relatively weak performance limitation strategy to meet the user's device performance requirements to the greatest extent.

[0144] For example, metal materials generally have higher thermal conductivity than insulating materials. That is, the temperature of the outer shell perceived by the user is relatively lower when using an insulating material protective shell than when using a metal material protective shell. Electronic devices can use relatively weak performance limitation strategies to maximize the user's device performance requirements.

[0145] In some embodiments, the electronic device may also set a thermal control strategy for all protective shells of different thicknesses and materials, that is, the thickness and material of the protective shells are not identified or differentiated.

[0146] like Fig.12 As shown in (a) and (b) of FIG. 1 , it is assumed that the highest hot spot temperature on the outer shell surface is 46°C and the highest hot spot temperature on the protective shell surface is 44°C. Assuming that the highest temperature hot spot is located on the rear shell of the outer shell, Fig.12 For (a), no protective case is used on the outer shell, and the electronic device uses a thermal control strategy corresponding to 46°C for temperature control. For example, the frame rate of a currently opened game application is limited to a maximum of 60FPS, and the refresh rate of the display is also limited to a maximum of 60Hz. Fig.12 For example, the frame rate of a game application currently opened is limited to a maximum of 90FPS, and the refresh rate of the display is also limited to a maximum of 90Hz. Fig.12 (a) in the figure adopts the thermal control strategy corresponding to 46°C, which can achieve greater performance release.

[0147] In some embodiments, taking the safety temperature of the device surface temperature as 48°C as an example, assuming that the highest temperature hotspot is located on the outer shell, and the protective shell is not used, the highest hotspot temperature on the outer shell surface is 48°C. When the temperature approaches 48°C, stricter performance restrictions are required to prevent the hotspot temperature on the outer shell surface from exceeding 48°C. In the case of using a protective shell, the highest hotspot temperature on the protective shell surface is 48°C, and performance restrictions are made based on the hotspot temperature on the protective shell surface. In this case, if the highest hotspot temperature on the protective shell surface is 48°C, assuming that the highest hotspot temperature on the outer shell surface is 53°C, compared to not using a protective shell, when the hotspot temperature on the outer shell surface is close to 48°C, the device performance is released more, resulting in the hotspot temperature on the outer shell surface rising to 53°C.

[0148] In actual application scenarios, considering that there may be fitting errors in the hotspot temperature on the surface of the protective shell, in order to maximize the safety of the user's device use, the maximum hotspot temperature on the surface of the protective shell can be set to be slightly lower than 48°C, for example, 47°C. In this case, the maximum hotspot temperature on the surface of the shell will still be greater than 48°C, which is more effective than the hotspot temperature on the surface of the shell strictly following the requirement that the hotspot temperature on the surface of the shell does not exceed 48°C in the related art. And for the related art, when using a protective shell, even if the use of a protective shell will change the hotspot temperature on the surface of the shell, the hotspot temperature on the surface of the shell generally varies within 0~1°C relative to the situation where the protective shell is not used (for example, the hotspot temperature on the surface of the shell obtained by fitting is 48°C, but due to the use of a protective shell, the actual hotspot temperature on the surface of the shell may reach 49°C), which cannot reach the level of releasing the device performance, resulting in a significant increase in the hotspot temperature on the surface of the shell.

[0149] Please also see Fig.13 , is a flow chart of a temperature control method provided by another embodiment of the present application. Taking the identification of whether a protective shell is used on the housing and whether a protective film is used on the display screen as an example for explanation.

[0150] 131: The electronic device identifies whether a protective case is used on the housing in response to a preset trigger condition.

[0151] Step 131 of the embodiment of the present application is similar to step 111 of the aforementioned embodiment, and will not be described again here to avoid repetition.

[0152] 132: If it is determined that no protective case is used on the housing, the electronic device continues to identify whether a protective film is used on the display screen.

[0153] In some embodiments, whether a protective film is used on the display screen can be identified by the above-mentioned method for identifying the protective film, which will not be described in detail here.

[0154] 133: If it is determined that no protective film is used on the display screen, the electronic device uses a default thermal control strategy to control the temperature.

[0155] In some embodiments, the default thermal control strategy can be set according to demand, and the embodiments of the present application are not limited to this.

[0156] 134: If it is determined that a protective film is used on the display screen, the electronic device obtains the thickness of the protective film.

[0157] Step 134 of the embodiment of the present application is similar to step 903 of the aforementioned embodiment, and will not be described again here to avoid repetition.

[0158] 135: The electronic device uses a thermal control strategy corresponding to the thickness of the protective film for temperature control.

[0159] Step 135 of the embodiment of the present application is similar to step 904 of the aforementioned embodiment, and will not be described again here to avoid repetition.

[0160] 136: If a protective case is used on the housing, the electronic device obtains the material and / or thickness of the protective case.

[0161] Step 136 of the embodiment of the present application is similar to step 113 of the aforementioned embodiment, and will not be described again here to avoid repetition.

[0162] 137: The electronic device recognizes whether a protective film is used on the display screen.

[0163] In some embodiments, whether a protective film is used on the display screen can be identified by the above-mentioned method for identifying the protective film, which will not be described in detail here.

[0164] 138: If it is determined that no protective film is used on the display screen, the electronic device uses a thermal control strategy corresponding to the material and / or thickness of the protective cover to control the temperature.

[0165] Step 138 of the embodiment of the present application is similar to step 114 of the aforementioned embodiment, and will not be described again here to avoid repetition.

[0166] 139: If it is determined that a protective film is used on the display screen, the electronic device obtains the thickness of the protective film.

[0167] Step 139 of the embodiment of the present application is similar to step 903 of the aforementioned embodiment, and will not be described again here to avoid repetition.

[0168] 140: The electronic device uses a thermal control strategy corresponding to the thickness of the protective film and the material and / or thickness of the protective shell to control the temperature.

[0169] In the scenario where both a protective film and a protective case exist, the hotspot temperature on the surface of the protective film and the hotspot temperature on the surface of the protective case can be comprehensively considered, and the device performance can be limited based on the highest hotspot temperature of the two. Temperature control can be implemented based on the thermal control strategy corresponding to the protective case and the protective film to avoid the hotspot temperature being too high and affecting the safety of users using the device.

[0170] In the scenario where only a protective film exists, the hotspot temperature of the fitted protective film surface and the hotspot temperature of the fitted outer shell surface can be comprehensively considered, and the device performance can be limited based on the highest hotspot temperature of the two to maximize the user's device performance requirements and avoid the impact of excessively high hotspot temperatures on the user's use of the device.

[0171] In a scenario where only a protective case exists, the hotspot temperature of the protective case surface and the hotspot temperature of the display screen surface can be comprehensively considered, and device performance can be limited based on the highest hotspot temperature of the two to maximize the user's device performance requirements and avoid the impact of excessively high hotspot temperatures on the user's use of the device.

[0172] In a scenario where there is no protective film or protective case, the hotspot temperature of the fitted shell surface and the hotspot temperature of the fitted display surface can be comprehensively considered, and the device performance can be limited based on the highest hotspot temperature of the two to maximize the user's device performance requirements and avoid the impact of excessively high hotspot temperatures on the user's use of the device.

[0173] like Fig.14 , which is a schematic diagram of the interaction between various modules in the electronic device provided in an embodiment of the present application.

[0174] 141: In response to a preset trigger condition, the accessory identification service obtains protection accessory information.

[0175] In some embodiments, the preset trigger condition may refer to a condition that triggers the accessory identification service to identify whether a protective case is used on the housing and / or whether a protective film is used on the display screen, which is not limited in the embodiments of the present application. The protective accessory information may include at least one of the following: whether a protective film is used on the display screen, the thickness of the protective film, whether a protective case is used on the housing, the material of the protective case, and the thickness of the protective case.

[0176] 142: The accessory identification service sends the protection accessory information to the thermal control strategy setting service.

[0177] For example, the protective accessory information is that a protective case is not used on the shell and a protective film is not used on the display. For another example, the protective accessory information is that a protective case is not used on the shell, and a protective film is used on the display. For another example, the protective accessory information is that a protective case is used on the shell, and a protective film is not used on the display. For another example, the protective accessory information is that a protective case is not used on the shell, and a protective film is used on the display, and the thickness of the protective film is X1 mm. For another example, the protective accessory information is that a plastic protective case is used on the shell, and a protective film is not used on the display.

[0178] 143: The thermal control strategy setting service sets the thermal control strategy corresponding to the protection accessory information.

[0179] In some embodiments, different protection accessory information may correspond to different thermal control strategies. A mapping relationship between multiple protection accessory information and multiple thermal control strategies may be pre-stored in the electronic device, and one protection accessory information corresponds to one thermal control strategy, so as to achieve more accurate temperature control of the electronic device, and meet the user's device performance requirements to the greatest extent without affecting the safety of the user in the process of using the device.

[0180] For electronic devices, it is possible to add options for protective accessories in the control center, or add a setting interface for protective accessories in the setting application, so that the user can actively choose whether the electronic device has a protective case and / or film. The electronic device can perform corresponding thermal control strategies based on the protective accessory information set by the user.

[0181] like Fig.15 1004 shows that the user sets whether the electronic device uses a protective case and / or a film through the setting application. The electronic device can display a protective accessory interface 1005 in response to the user's operation on the setting application. The protective accessory interface 1005 includes four control options: a control option 1006 for not using a protective case and not using a protective film, a control option 1007 for only using a protective case, a control option 1008 for only using a protective film, and a control option 1009 for using a protective case and a protective film. The user can set the protective accessory information of the electronic device by checking the control options.

[0182] In some embodiments, the protective accessory information obtained by intelligent identification can also be displayed in visual ways such as pop-up windows (which may disappear automatically after a period of time), notification bars, and floating prompts (which may disappear automatically after a period of time).

[0183] In some embodiments, the visually displayed protective accessory information may also provide controls for the user to confirm and / or provide feedback on erroneous recognition results, thereby enhancing the accuracy of intelligent recognition.

[0184] See also Fig.16As shown, a temperature control method provided by an embodiment of the present application is provided. The temperature control method can be applied to electronic equipment. The temperature control method can include the following steps: 161: When the electronic device is not using protective accessories, a first thermal control strategy is used to control the temperature of the device.

[0185] In some embodiments, the protective accessories include but are not limited to protective films and protective cases. If the electronic device does not use protective accessories, a default thermal control strategy (referred to as a first thermal control strategy) may be used to control the device temperature. The default thermal control strategy may be a thermal control strategy described in the relevant technology to limit the performance of the functional modules in the electronic device according to the highest hot spot temperature on the display screen surface and the shell surface, so as to avoid excessive hot spot temperature affecting the safety of the user using the device.

[0186] 162: When the electronic device uses a protective accessory, a second thermal control strategy different from the first thermal control strategy is used to control the temperature of the device.

[0187] In some embodiments, the first thermal control strategy and the second thermal control strategy may both include adjusting the operating parameters of at least one of the following: a processor, a memory, a display screen, a communication module, an audio module, a camera module, and a battery charging and discharging module.

[0188] In some embodiments, under normal circumstances, the use of protective accessories on electronic devices will cause the surface temperature of the device to increase. For protective accessories with better heat dissipation effects, the surface temperature of the device may also decrease to a certain extent.

[0189] In some embodiments, adjusting the working parameters of the processor, memory, display, communication module, audio module, camera module, battery charging and discharging module, etc. may refer to: adjusting the frequency of the processor, etc., adjusting the frequency of the memory, etc., adjusting the brightness, frame rate, refresh rate, etc. of the display screen, adjusting the antenna power, communication frequency band, network rate, etc. in the communication module, adjusting the tone and loudness of the audio module, adjusting the shooting frame rate of the camera module, turning off the flash, turning off the beauty algorithm, etc., adjusting the charging current, battery discharge current, etc.

[0190] In some embodiments, the electronic device can determine whether protective accessories are used and the protective accessory information used through intelligent identification, or the user manually sets the protective accessory information of the electronic device, and the electronic device can directly obtain the protective accessory information to determine whether protective accessories are used and which protective accessories are used.

[0191] For example, a setting interface for protective accessories is added to the setting application. The temperature control method may also include: in response to a first operation on the setting application, displaying a first interface (an interface for setting protective accessories), the first interface including a control for setting protective accessories used by the electronic device, and the user can set the protective accessories information of the electronic device through the control operation; based on a second operation of the user on the control, determining the protective accessories used by the electronic device.

[0192] In some embodiments, the protective accessory may include a protective film disposed on the display screen, and a second thermal control strategy different from the first thermal control strategy is used to control the device temperature, which may include: obtaining a first hot spot temperature on the surface of the protective film and a second hot spot temperature on the surface of the housing; and controlling the device temperature based on the second thermal control strategy and the larger of the first hot spot temperature and the second hot spot temperature. Through the above scheme, the second thermal control strategy may include thermal control parameters corresponding to multiple thermal control temperatures. In the case of using only the protective film, the corresponding thermal control parameters may be found from the second thermal control strategy based on the larger of the hot spot temperature on the surface of the protective film and the hot spot temperature on the surface of the housing, and the device temperature may be controlled based on the thermal control parameters to achieve the greatest satisfaction of the user's device performance requirements.

[0193] In some embodiments, controlling the device temperature based on the thermal control parameters may refer to adjusting the operating parameters of the corresponding hardware modules based on the thermal control parameters to reduce the device temperature or suppress excessive temperature growth of the device.

[0194] In some embodiments, protective films of different thicknesses may also be set to correspond to different second thermal control strategies, and device temperature control may be performed based on the second thermal control strategy corresponding to the thickness of the protective film and the larger of the first hot spot temperature and the second hot spot temperature. That is, based on the larger of the first hot spot temperature and the second hot spot temperature, the corresponding thermal control parameters are searched from the corresponding second thermal control strategy to perform device temperature control.

[0195] In some embodiments, the surface temperature of the device and the surface temperature of the protective accessories can be obtained by fitting the temperature sensor data inside the electronic device. For example, the electronic device includes multiple first sensors for sensing the temperature of the display screen and multiple second sensors for sensing the temperature of the outer shell. Acquiring the first hotspot temperature on the surface of the protective film and the second hotspot temperature on the surface of the outer shell may include: fitting the temperatures of multiple first position points on the surface of the protective film based on the temperature sensing data of the multiple first sensors, and taking the maximum value of the temperatures of the multiple first position points as the first hotspot temperature; fitting the temperatures of multiple second position points on the surface of the outer shell based on the temperature sensing data of the multiple second sensors, and taking the maximum value of the temperatures of the multiple second position points as the second hotspot temperature. For another example, fitting the temperatures of multiple third position points on the surface of the display screen based on the temperature sensing data of the multiple first sensors, and taking the maximum value of the temperatures of the multiple third position points as the third hotspot temperature; fitting the temperatures of multiple fourth position points on the surface of the protective shell based on the temperature sensing data of the multiple second sensors, and taking the maximum value of the temperatures of the multiple fourth position points as the fourth hotspot temperature.

[0196] In some embodiments, determining whether there is a protective film on the display screen and the thickness of the protective film can be achieved in the following manner: in response to a first touch operation on the display screen, acquiring sensing data of a third sensor, where the third sensor may be a capacitive touch sensor provided by the display screen or an additional elastic wave sensor; based on the sensing data of the third sensor, determining whether there is a protective film on the display screen and the thickness of the protective film.

[0197] In some embodiments, the protective accessory includes a protective shell disposed on the housing, and a second thermal control strategy different from the first thermal control strategy is used to control the device temperature, which may include: obtaining a third hot spot temperature on the surface of the display screen and a fourth hot spot temperature on the surface of the protective shell; and controlling the device temperature based on the second thermal control strategy and the larger of the third hot spot temperature and the fourth hot spot temperature. That is, when only the protective shell is used, the corresponding thermal control parameters can be found from the second thermal control strategy based on the larger of the hot spot temperature on the surface of the protective shell and the hot spot temperature on the surface of the display screen, and the device temperature can be controlled based on the thermal control parameters to achieve the greatest satisfaction of the user's device performance requirements.

[0198] In some embodiments, protective shells of different thicknesses or materials can also be set to correspond to different second thermal control strategies, and the material and / or thickness of the protective shell can be obtained, and the device temperature can be controlled based on the second thermal control strategy corresponding to the material and / or thickness of the protective shell and the larger of the third hot spot temperature and the fourth hot spot temperature. That is, based on the larger of the third hot spot temperature and the fourth hot spot temperature, the corresponding thermal control parameters are searched from the corresponding second thermal control strategy to control the device temperature.

[0199] In some embodiments, the protective accessories include a protective film disposed on the display screen and a protective shell disposed on the housing, and a second thermal control strategy different from the first thermal control strategy is used to control the device temperature, including: obtaining a first hotspot temperature on the surface of the protective film and a fourth hotspot temperature on the surface of the protective shell; and controlling the device temperature based on the second thermal control strategy and the larger of the first hotspot temperature and the fourth hotspot temperature. That is, when the protective film and the protective shell are used at the same time, the corresponding thermal control parameters can be found from the second thermal control strategy based on the larger of the hotspot temperature on the surface of the protective film and the hotspot temperature on the surface of the protective shell, and the device temperature can be controlled based on the thermal control parameters to achieve the greatest satisfaction of the user's device performance requirements.

[0200] In some embodiments, the second thermal control strategy may be further determined based on the thickness of the protective film and the material and / or thickness of the protective shell.

[0201] In some embodiments, the detection method of the protective shell may include multiple methods, for example: based on the connection information of the first interface, determine whether the protective shell is provided on the shell, and the first interface may include a USB interface or an interface electrically connected to a Pogopin. For another example, the protective shell includes a Hall sensor, and it can be determined whether the protective shell is provided on the shell based on the sensing data reported by the Hall sensor. For another example, the electronic device includes a wireless charging module. When the electronic device is charged based on the wireless charging module, by obtaining the transmission power and quality factor during the wireless charging process, it can be determined whether the protective shell is provided on the shell based on the transmission power and quality factor. For another example, when the user holds the electronic device in his hand and touches the display screen, the presence or absence of a protective shell will affect the signal amount of the touch. Specifically, in response to the second touch operation on the display screen, the signal amount of the second touch operation is obtained. The second touch operation is an operation in which the user holds the electronic device in his hand and touches the display screen; based on the signal amount of the second touch operation, it is determined whether the protective shell is provided on the shell. For another example, the electronic device may reuse existing sensors or set additional sensors to detect the protective shell. Specifically, the sensing data of the fourth sensor used to detect the protective shell is obtained, and the fourth sensor includes one of the following: elastic wave sensor, acceleration + gyroscope sensor, light sensor, capacitive touch sensor; based on the sensing data of the fourth sensor, determine whether a protective shell is provided on the shell. For another example, the presence or absence of a protective shell will affect the temperature difference between the hot zone and the cold zone. The detection of the protective shell can be achieved by obtaining the temperature difference between the hot zone and the cold zone. Specifically, the preset hot zone temperature and the preset cold zone temperature of the electronic device in a high-heat state are obtained. The high-heat state includes a charging state or a hardware performance overload state; based on the temperature difference between the preset hot zone temperature and the preset cold zone temperature, determine whether a protective shell is provided on the shell.

[0202] In some embodiments, when it is intelligently recognized that the electronic device is using protective accessories, a visual prompt can be given to the user. For example, when it is determined that the electronic device is using protective accessories, a first window is displayed, and the first window includes information about the protective accessories.

[0203] See also Fig.17 As shown, a temperature control method provided by an embodiment of the present application is provided. The temperature control method can be applied to electronic equipment. The temperature control method can include the following steps: 171: When the electronic device is not using protective accessories, the maximum surface temperature of the electronic device is less than or equal to the safety temperature. The surface temperature includes the temperature of the display surface and the temperature of the casing surface.

[0204] In some embodiments, in order to ensure the safety of users when using the device, the surface temperature of the electronic device cannot exceed the safety temperature. For example, the surface of the electronic device in the bare device form includes the display surface and the shell surface, that is, the temperature of the display surface and the shell surface cannot exceed the safety temperature.

[0205] 172: When electronic equipment uses protective accessories, the maximum surface temperature of the electronic equipment may be greater than the safety temperature.

[0206] Generally speaking, when the electronic device uses protective accessories, the device temperature perceived by the user is lower than when the protective accessories are not used. That is, when the protective accessories are used, the maximum value of the device surface temperature is allowed to be greater than the safety temperature. In this case, due to the presence of the protective accessories, the temperature of the surface of the protective accessories is less than or equal to the safety temperature, which will not affect the safety of the user when using the device, and can meet the user's device performance requirements to the greatest extent.

[0207] In some embodiments, when the electronic device uses a protective accessory, the difference between the maximum surface temperature of the electronic device and the safety temperature may be greater than a first preset value. The first preset value is related to the heat dissipation / insulation capability of the protective accessory, for example, the first preset value may be 2°C, 3°C, etc.

[0208] See also Fig.18 As shown, a temperature control method provided by an embodiment of the present application is provided. The temperature control method can be applied to electronic equipment. The temperature control method can include the following steps: 181: If the electronic device does not use a protective accessory, the performance of the electronic device in the first preset scenario is the first performance.

[0209] In some embodiments, the performance of the electronic device may include at least one of the following: processor performance (e.g., processor frequency), memory performance (e.g., memory frequency), display performance (e.g., display refresh rate), communication module performance (e.g., antenna frequency), audio module performance (e.g., audio pitch / loudness), camera module performance (e.g., camera frame rate), battery charging and discharging module performance (e.g., charging current, discharging current).

[0210] 182: If the electronic device uses a protective accessory, the performance of the electronic device in the first preset scenario is a second performance, and the second performance is higher than the first performance.

[0211] In some embodiments, the device temperature perceived by the user when using protective accessories is lower than the device temperature perceived by the user when not using protective accessories. In the same scenario, when using protective accessories, the device may be allowed to work using relatively relaxed working parameters and performance release is relaxed, while when not using protective accessories, the device uses relatively tightened working parameters and performance release is tightened. That is, in the same scenario, the performance of the device using protective accessories can be set higher than the performance of the device not using protective accessories, so as to meet the user's device performance requirements to the greatest extent. For example, in the same scenario, the highest hot spot temperature on the surface of the device is the same, and the use of protective accessories causes the user to perceive a lower device temperature than the user perceives when not using protective accessories, and thus the performance of the device using protective accessories can be set higher than the performance of the device not using protective accessories.

[0212] In some embodiments, the second performance being higher than the first performance may mean that in the same scenario, when protective accessories are used compared to when no protective accessories are used: the processor frequency may be higher, or the memory frequency may be higher, or the display refresh rate / brightness may be higher, or the camera frame rate may be higher, or the charging current may be larger, etc.

[0213] In some embodiments, in the second preset scenario, the difference between the maximum value of the surface temperature of the electronic device when the protective accessories are used and the maximum value of the surface temperature when the protective accessories are not used is greater than the second preset value. The second preset scenario can be a scenario where the surface temperature of the device is close to the safety temperature. For example, when the protective accessories are not used, the surface temperature of the bare device is close to the safety temperature; when the protective accessories are used, the temperature of the surface of the protective accessories is close to the safety temperature, while the surface temperature of the device is greater than the safety temperature. The second preset value is related to the heat dissipation / insulation capacity of the protective accessories. For example, the second preset value can be 3°C, 4°C, etc.

[0214] That is, the maximum surface temperature of an electronic device when using protective accessories may be significantly greater than the maximum surface temperature when not using protective accessories.
