In order to make the purpose, technical solutions and advantages of the present application more clearly understood, the present application will be described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application.

In one embodiment, a heating circuit is provided on a preset component of the mobile device, the preset component is a casing or a casing, and the material used to prepare the casing of the mobile device may be ceramic or stainless steel. Wherein, the heating circuit may be a thick-film circuit, which may be heated based on a thick-film heating technology.

Optionally, referring to FIG. 1 , in the process of preparing the mobile device, the electronic paste used for preparing the heating circuit may be made into a resistor on the inner side of the casing 10 of the mobile device through a process such as screen printing, film sticking, and sintering. Traces are formed to form the heating circuit 20, and the heating circuit 20 is placed on the inside of the housing 10, so that the two are arranged in close contact.

It should be understood that the resistance traces made in the casing of the mobile device may be one or a combination of multiple line segment styles such as straight lines, circular arc lines, etc., only one of which is shown in FIG. 1 . way of example.

And when the mobile device assembles the battery assembly and the casing, the power pins of the heating circuit inside the casing can also be connected to the battery interface, so that the battery of the mobile device can supply power to the heating circuit.

Alternatively, the heating circuit can also be made inside the outer casing of the mobile device (for example, if the mobile device is a smart phone, the outer casing is the mobile phone casing), and when the mobile device is nested in the outer casing , the heating circuit on the inner side of the outer casing is attached to the outer side of the outer casing of the mobile device, and is arranged in close contact with the outer casing. Moreover, the power pin of the heating circuit is also connected with a power plug. When the mobile device is nested in the outer casing, the power plug can be inserted into the power interface of the mobile device, so that the battery of the mobile device can be powered by the power interface. The heating circuit inside the housing is powered. Of course, if other electronic components for controlling the heating circuit are also arranged in the outer casing, the battery of the mobile device can also supply power to these electronic components through the power interface.

Further, referring to FIG. 2 , the antifreeze method of the mobile device includes:

Step S10, detecting whether the user is in contact with the mobile device through a touch sensor;

Step S20, if yes, detect whether the current ambient temperature is less than or equal to a preset threshold;

Step S30, when it is detected that the current ambient temperature is less than or equal to the preset threshold, control the heating circuit to heat the preset component.

In this embodiment, the execution terminal of the embodiment may be a mobile device (such as a mobile portable device such as a mobile phone and a tablet computer), or a heating device of a mobile device. When the heating circuit is connected to the mobile device through the outer casing of the mobile device When the outer casing of the mobile device is tightly attached, the execution terminal can also be the outer casing; of course, even if the heating circuit is tightly attached to the outer casing of the mobile device through the outer casing of the mobile device, the execution terminal can still be a mobile device. The following description is given by taking the execution terminal as a mobile device as an example.

As described in step S10: the casing of the mobile device may be provided with a touch sensor, or when the heating circuit is tightly attached to the casing of the mobile device through the casing of the mobile device, a touch sensor is disposed on the outer side of the casing .

Optionally, the terminal can capture the touch signal of the human body through the touch sensor, so as to judge whether the user is in contact with the mobile device. For example, when the user holds the mobile device, the terminal can capture the human biometrics through the touch sensor, and then detect the corresponding touch signal, and then determine that the user is currently touching the mobile device, that is, the user is in contact with the mobile device. When the mobile device is placed on the support object, although the support object is in contact with the mobile device, since the terminal cannot capture the corresponding human biometric features, it can be determined that the corresponding touch signal is not detected.

It should be understood that when the mobile device is nested in the outer casing, so that the heating circuit provided in the outer casing can be tightly attached to the outer casing of the mobile device, when the terminal detects a corresponding touch signal through the touch sensor on the outer casing At this time, it can also be determined that the user is currently in contact with the mobile device.

As described in step S20: when the terminal detects through the touch sensor that the user is currently in contact with the mobile device, the terminal may further acquire the current ambient temperature and detect whether the current ambient temperature is less than or equal to a preset threshold.

Wherein, the preset threshold value (which can be recorded as the first preset threshold value) is used to measure the degree of freezing caused by the casing or the outer casing of the mobile device to the human body, and when the temperature is less than or equal to the preset threshold value, the human body will be significantly Therefore, the preset threshold value may be set to be slightly lower than the normal temperature value, such as setting the preset threshold value to be less than or equal to 25°C.

Optionally, the terminal may detect the temperature of the casing or casing of the mobile device through a temperature sensor as the current ambient temperature. Wherein, the temperature sensor may be arranged on the mobile device or the casing.

As described in step S30: when the terminal detects that the current ambient temperature is less than or equal to the preset threshold, it starts the heating circuit attached to the casing of the mobile device, and generates heat by energizing the heating circuit to control the heating circuit to be the mobile device's Preset part heating.

Of course, when the heating circuit is arranged on the casing, the heating circuit heats the casing of the mobile device, that is, heating the casing.

In one embodiment, a heating circuit is provided to heat the casing or the casing of the mobile device when the ambient temperature is too low, so as to realize the antifreeze of the mobile device and avoid holding the mobile device due to the low temperature of the casing of the mobile device. of user discomfort occurs, improving the user experience of using the mobile device.

In an embodiment, as shown in FIG. 3 , based on the embodiment shown in FIG. 2 above, the current ambient temperature is the temperature of the outer casing or the outer casing, and the preset threshold is the first preset temperature. Setting a threshold value; after the step of controlling the heating circuit to heat the preset component when it is detected that the current ambient temperature is less than or equal to the preset threshold value, the method further includes:

Step S40, detect whether the current ambient temperature is greater than or equal to a second preset threshold, and the second preset threshold is greater than the first preset threshold;

Step S41, if yes, turn off the heating circuit.

In this embodiment, the current ambient temperature is the temperature of the casing or the casing (both can be recorded as casing temperature).

Optionally, when the terminal detects that the current ambient temperature is less than or equal to the first preset threshold, the terminal controls the heating circuit to heat the preset components of the mobile device. The following description takes the preset component as the shell as an example.

Optionally, a temperature sensor is provided on the mobile device or the casing, and the terminal can detect the temperature of the casing of the mobile device through the temperature sensor.

Optionally, when the terminal activates the heating circuit to heat the casing, the casing temperature can be updated and acquired in real time, and whether the casing temperature is greater than or equal to the second preset threshold can be detected. The second preset threshold is used to measure the degree of warmth perceived by the human body, and when the temperature is greater than or equal to the second preset threshold, the human body will obviously feel that the temperature is overheated, so the second preset threshold can be set not only Greater than the first preset threshold, the second preset threshold may also be higher than the normal temperature value, for example, the value range of the second preset threshold is set to be 30°C-35°C.

Optionally, when the terminal detects that the temperature of the casing is lower than the second preset threshold, it continues to control the heating circuit to heat the casing until the terminal detects that the temperature of the casing is greater than or equal to the second preset threshold, then closes the heating circuit, and stops as The casing is heated to avoid overheating of the casing or casing to cause discomfort to the user holding the mobile device, or to avoid damage to some electronic components of the mobile device due to overheating of the casing or casing.

Further, after the terminal turns off the heating circuit when the casing temperature is greater than or equal to the second preset threshold, even when it is detected again that the casing temperature drops below the second preset threshold, there is no need to immediately restart the heating circuit to heat the casing, Instead, when it is detected that the temperature of the casing drops to a temperature below the first preset threshold, the heating circuit is restarted to heat the casing until the temperature of the casing reaches the second preset threshold again, and so on and so forth, so as to control the temperature of the casing to maintain at the first threshold. Within the temperature range formed by a preset threshold value and a second preset threshold value, the casing of the mobile device is neither overheated nor overcooled.

In this way, it is avoided that the casing of the mobile device may cause discomfort to the user due to over-cooling or overheating.

In an embodiment, on the basis of the foregoing embodiment, the step of controlling the heating circuit to heat the preset component includes:

Step S50: Determine heating heat energy according to the difference between the current ambient temperature and the second preset threshold, and determine the power of the heating circuit according to the square resistance and voltage value corresponding to the heating circuit;

Step S51, determining a preset heating duration according to the heating heat energy and the power;

Step S52 , according to the preset heating duration, control the duration of heating the preset component by the heating circuit.

In this embodiment, the current ambient temperature is the temperature of the casing of the mobile device, or the temperature of the casing (both can be recorded as the casing temperature).

Optionally, when the terminal starts the heating circuit to heat the casing or casing of the mobile device, the terminal can determine the heating heat energy according to the difference between the current ambient temperature and the second preset threshold, and the specific calculation method is: Q=CMΔT .

Among them, Q is the theoretical heat energy, C is the specific heat capacity of the heated element (determined by the material of the casing or casing of the mobile device), M is the mass of the heated element, and ΔT is the current ambient temperature and the second preset threshold. difference.

And since the thermal efficiency of the thick film circuit is 97%, the heating heat energy required for actual heating is finally calculated as: W=97%Q.

At the same time, the terminal can also determine the power P of the heating circuit according to the corresponding square resistance and voltage value of the heating circuit. The specific calculation formula is as follows:

Among them, U is the voltage of the heating circuit (it can be a rated voltage value, such as 5V), r is the square resistance of the heating circuit, and K is the average coefficient of resistance temperature. Because the square resistance of the heating circuit will change with the increase of temperature, it is necessary to introduce the average coefficient of resistance temperature to calculate the heating power.

further,

where R2 is the resistance value when the temperature reaches the second preset threshold (it can be pre-measured and stored in the storage of the terminal, for example, before the mobile device or the casing is shipped from the factory, after the casing temperature is heated to the second preset threshold, , record the resistance value of the heating circuit at this time as R2), R1 is the resistance value corresponding to the current ambient temperature, which can be detected in real time; ΔT is the difference between the current ambient temperature and the second preset threshold;

where h is the thickness of the thick film in the heating circuit, w is the width of the thick film, L is the length of the thick film, and ρ is the resistivity.

Optionally, after the terminal calculates and obtains the heating heat energy W and the power P of the heating circuit required to heat the current ambient temperature to the second preset threshold, it can heat the current ambient temperature to the second preset threshold based on this calculation. The required preset heating time t is:

Further, when the terminal controls the heating circuit to heat the casing of the mobile device based on the preset heating duration, it will start recording the heating duration (that is, the running duration of the heating circuit) when the heating circuit is activated, and detect in real time whether the heating duration has reached the preset duration. Set the heating time.

Optionally, when the terminal detects that the heating duration reaches the preset heating duration, the terminal directly turns off the heating circuit and stops heating the casing of the mobile device. In this way, when the terminal detects that the housing temperature is greater than or equal to the second preset threshold, or detects that the heating time reaches the preset heating time, it can control the heating circuit to turn off, so as to avoid the failure to turn off the heating due to the failure of the temperature control circuit This prevents the case from overheating and scalding the user or damaging the mobile device.

Optionally, after the terminal turns off the heating circuit when the heating duration reaches the preset heating duration, and when the terminal detects that the temperature of the casing has dropped to a temperature equal to or below the first preset threshold value, restart the heating circuit to heat the casing, and restart the heating circuit. Record the heating duration and recalculate the preset heating duration until the temperature of the casing reaches the second preset threshold again, or until the heating duration reaches the preset heating duration again, and so on and so forth, so that the casing of the mobile device does not overheat or overheat. cold.

In this way, by pre-calculating the preset heating time required when the temperature of the housing reaches the second preset threshold, and controlling the heating circuit to heat the housing or the housing cover of the mobile device within the preset heating time, so as to avoid the temperature control circuit Failure to turn off the heating circuit occurs, thereby preventing the case from overheating and scalding the user or damaging the mobile device.

In an embodiment, on the basis of the above-mentioned embodiment, after the step of detecting whether the current ambient temperature is greater than or equal to a second preset threshold value, the method further includes:

Step S60, if yes, detect whether the heating duration of the heating circuit is greater than a preset duration;

Step S61, when it is detected that the heating duration is greater than the preset duration, reducing the power of the heating circuit;

Step S62, when it is detected that the heating duration is less than or equal to the preset duration, the heating circuit is turned off.

In this embodiment, when the heating circuit is activated to heat the casing of the mobile device, the heating duration of the heating circuit is simultaneously recorded. Moreover, in this embodiment, the closing condition for limiting the heating circuit must first be satisfied: the housing temperature is greater than or equal to the second preset threshold. That is, if the housing temperature does not reach the second preset threshold, even if the heating time reaches the preset heating time, the heating circuit will not be turned off.

Optionally, when the terminal starts the heating circuit to heat the casing, the casing temperature can be updated and obtained in real time, and whether the casing temperature is greater than or equal to the second preset threshold can be detected. And when the terminal detects that the housing temperature is greater than or equal to the second preset threshold, it may temporarily not turn off the heating circuit, but further detect whether the heating duration of the heating circuit is greater than the preset duration.

The preset duration is used to measure the efficiency of the heating circuit for heating the casing of the mobile device, and when the heating duration is less than or equal to the preset duration, it indicates that the current heating efficiency is high (the target is achieved with a shorter heating duration). heating temperature); when the heating time is longer than the preset time, it indicates that the current heating efficiency is low. The calculation method of the preset duration may be equivalent to the calculation method of the preset heating duration, or may be a fixed value preset according to actual needs.

Optionally, when the terminal detects that the temperature of the casing is greater than or equal to the second preset threshold, if it detects that the heating duration of the heating circuit is less than or equal to the preset duration, the terminal directly controls the heating circuit to turn off to stop the casing of the mobile device. or heating the casing, thereby avoiding overheating of the casing or casing, which may cause discomfort to the user holding the mobile device, or avoid damage to the mobile device due to overheating of the casing or casing. Of course, when the terminal detects that the housing temperature is lower than the second preset threshold, even if the detected heating duration is longer than the preset duration, the heating circuit will not be directly turned off.

Optionally, when the terminal detects that the casing temperature is greater than or equal to the second preset threshold, if it simultaneously detects that the heating duration of the heating circuit is greater than the preset duration, it indicates that the current heating circuit has a low efficiency for heating the casing of the mobile device ( If it may be caused by the large temperature difference between the current indoor temperature or outdoor temperature and the second preset threshold), then if the heating circuit is directly turned off at this time, the casing of the mobile device may be rapidly cooled (even rapidly drop to the first preset threshold or below), at this time, the heating circuit has to be turned on again to heat the casing or casing of the mobile device, so that the heating circuit is frequently opened and closed, which affects the service life of the heating circuit.

Therefore, when the terminal detects that the housing temperature is greater than or equal to the second preset threshold, if it simultaneously detects that the heating duration of the heating circuit is greater than the preset duration, the power of the heating circuit is reduced, and the heating circuit is controlled to continue to maintain the reduced power operation to avoid rapid cooling of the case temperature.

Optionally, the terminal may reduce the voltage of the heating circuit to reduce the power of the heating circuit.

Optionally, when the terminal detects that the housing temperature is greater than or equal to the second preset threshold, if it detects that the heating duration of the heating circuit is greater than the preset duration at the same time, the power of the heating circuit is reduced to the minimum power, and then the heating circuit is controlled to Minimum power to maintain operation.

In this way, by reducing the power of the heating circuit and controlling the heating circuit to continue to operate at the reduced power, it is possible to prevent the temperature of the housing from cooling down too quickly, and at the same time, to avoid frequent opening and closing of the heating circuit, which affects the service life of the heating circuit.

In an embodiment, on the basis of the above-mentioned embodiment, when it is detected that the current ambient temperature is less than or equal to the preset threshold, after the step of controlling the heating circuit to heat the preset component, further: include:

Step S70: When it is detected that the current ambient temperature is greater than or equal to a third preset threshold, reduce the power of the heating circuit, wherein the third preset threshold is greater than the first preset threshold, and the third preset threshold The preset threshold is smaller than the second preset threshold.

In this embodiment, the current ambient temperature is the temperature of the casing or the casing of the mobile device.

Optionally, when the terminal activates the heating circuit to heat the casing, the casing temperature can be updated and acquired in real time, and whether the casing temperature is greater than or equal to a third preset threshold can be detected. Wherein, the third preset threshold is greater than the first preset threshold, and the third preset threshold is less than the second preset threshold.

Optionally, the third preset threshold may be an average value between the first preset threshold and the second preset threshold.

Optionally, when the terminal detects that the temperature of the casing is lower than the third preset threshold, the heating circuit is controlled to continue to operate with the current operating parameters.

Optionally, when the terminal detects that the casing temperature is greater than or equal to the third preset threshold, it reduces the power of the heating circuit, and controls the heating circuit to continue heating the casing of the mobile device with the reduced power. And after that, if the terminal detects that the temperature of the casing is still rising slowly until it reaches the second preset threshold, the heating circuit is turned off, so as to avoid the casing temperature rising too fast before the terminal can close the heating circuit in the future. Instantaneously far higher than the second preset temperature, which could burn the user or damage the mobile device.

Optionally, if the terminal reduces the power of the heating circuit when the casing temperature is greater than or equal to the third preset threshold and the casing temperature is less than the second preset threshold, and then detects that the casing temperature exhibits a slow cooling trend , then when the terminal detects that the temperature of the casing has dropped to the first preset threshold, the power of the heating circuit is increased by increasing the voltage of the heating circuit, so as to restore the power of the heating circuit to the value before the reduction, and control the heating circuit to The restored heating power continues to operate to maintain the case temperature within a comfortable temperature range for the user.

Alternatively, if the terminal reduces the power of the heating circuit when the casing temperature is greater than or equal to the third preset threshold and the casing temperature is less than the second preset threshold, and then detects that the casing temperature presents a relatively stable state (that is, constant temperature state), the terminal controls the heating circuit to continue to maintain the current operating parameters, so as to maintain the casing temperature within a temperature range that is comfortable for the user.

Step S80, when the heating circuit is controlled to heat the preset component, the current ambient temperature is displayed on the display interface of the mobile device.

Optionally, when the terminal controls the heating circuit to heat the preset components of the mobile device (that is, the casing or the casing), the current ambient temperature can be detected and updated in real time, and the updated current ambient temperature can be displayed on the mobile device.
