In order to improve the heat generation of the electronic device, the temperature of the electronic device is controlled within a reasonable range, and various schemes can be adopted. Some of these solutions are directed to controlling the heat generation of the processor of the electronic device, and some require control depending on the temperature of the outer surface of the housing of the electronic device. Since the skin of the user directly contacts the outer surface of the housing of the electronic device during the use of the electronic device, and the sensed temperature is also the outer surface temperature of the housing of the electronic device, it is necessary to acquire the outer surface temperature of the housing of the electronic device and control the heat generating source (a functional module with serious heat generation) of the electronic device according to the outer surface temperature of the housing of the electronic device.
The electronic equipment provided by the embodiment of the application can acquire the accurate temperature of the outer surface of the shell of the electronic equipment. Taking an electronic device as a mobile phone as an example, please refer to fig. 1, and fig. 1 is a schematic view of a first structure of the electronic device according to an embodiment of the present disclosure. The electronic device 10 includes a housing 120, a connecting wire 140, a first temperature sensor 160, and a processor 180.
The housing 120 of the electronic device 10 may include a through hole 122; the through hole 122 may penetrate the housing 120, and it is also understood that the through hole 122 communicates the inside and the outside of the electronic apparatus 10.
The connection line 140 passes through the through hole 122, and the connection line 140 may be a conductive line.
The first temperature sensor 160 may be a thermocouple temperature sensor, a thermal resistance temperature sensor, or the like. For example, the temperature sensor may be a negative temperature coefficient resistor (NTC resistor). The first temperature sensor 160 is disposed on the outer surface 124 of the housing 120, and the first temperature sensor 160 can be used to obtain a first temperature value of the outer surface 124 of the housing 120 (e.g., a temperature value of the outer surface 124 of the housing 120).
The processor 180 is disposed in the housing 120, and the processor 180 is electrically connected to the first temperature sensor 160 through the connecting line 140 passing through the through hole 122, and is configured to obtain a first temperature value collected by the first temperature sensor 160.
The electronic device 10 of the present embodiment can acquire the first temperature value of the outer surface 124 of the housing 120 through the first temperature sensor 160 under different environments, the first temperature sensor 160 transmits the acquired first temperature value to the processor 180 of the electronic device 10 through the connection line 140 penetrating through the housing 120, so as to provide an accurate first temperature value of the outer surface 124 of the housing 120, and the electronic device 10 can acquire an accurate first temperature value of the outer surface 124 of the housing 120 through the connection line 140 penetrating through the housing 120.
Referring to fig. 2, fig. 2 is a second structural schematic diagram of an electronic device according to an embodiment of the present disclosure. The electronic device 10 further includes a function module 182 disposed in the housing 120, wherein the function module 182 is electrically connected to the processor 1820. Processor 180 is also configured to change an operating parameter of function module 182 to decrease the first temperature value when the first temperature value exceeds the temperature threshold.
Specifically, after the processor 180 of the electronic device 10 accurately obtains the first temperature value of the outer surface 124 of the housing 120, the temperature of the electronic device 10 can be controlled according to the first temperature value. For example, after the first temperature value exceeds the temperature threshold, the processor 180 may reduce power consumption of a part of the functional module 182 in the electronic device 10, so as to reduce heat generation in the electronic device 10 and reduce the temperature of the electronic device 10. The functional module 182 may be at least one of a main Chip (CPU), an image processing chip (GPU), a display screen, and the like. For example, the processor may reduce the operating frequency of the main Chip (CPU), the image processing chip (GPU), reduce the brightness and frame rate of the display screen, and so on.
In some embodiments, in order to obtain the temperature of the outer surface of the casing of the electronic device, a plurality of temperature sensors (NTC sensors) may be disposed on the main board of the electronic device, and these temperature sensors are close to the heat generating source inside the electronic device, and may be approximately regarded as the temperature of the casing of the electronic device. The temperature sensors are connected to a processor of the electronic device through connecting wires, and the processor of the electronic device can read the values of the temperature sensors so as to obtain temperature values.
The temperature of the electronic equipment acquired through the temperature sensor on the mainboard can only represent the temperature of the mainboard of the electronic equipment, and when the temperature of the outer surface of the shell of the electronic equipment needs to be accurately controlled, if the temperature of the mainboard is adopted, a large difference value exists in practice, and the condition of inaccurate control can be caused.
Therefore, a scheme of fitting the temperature of the outer surface of the shell can be adopted to obtain the temperature of the outer surface of the shell of the electronic device more accurately. The core thought is that a plurality of temperature sensors are added on the electronic equipment mainboard, each temperature sensor can acquire the temperature of one position in the electronic equipment, certain correlation exists between the temperature of the outer surface of the shell and the temperature acquired by the temperature sensors on the electronic equipment mainboard, and the correlation can be linear. And (4) fitting through some conventional algorithms, namely finally obtaining the outer surface temperature of the shell of the electronic equipment through the numerical value of the temperature sensor. The expression for a common fitting algorithm is:
T＝a0+a1x1+a2x2+..+anxn
wherein T is the outer surface temperature of the shell of the electronic equipment, xnIs the temperature of the nth temperature sensor, anIs the coefficient of the nth temperature sensor. In order to obtain a relatively accurate temperature of the outer surface of the housing, the coefficients need to be sufficiently accurate in addition to ensuring sufficient accuracy of the temperature sensor. Coefficient acquisition here is generally not calculated, but by a fitting algorithm.
The fitting process is that a thermocouple is pasted at the hottest heating point on the outer surface of the shell of the electronic equipment, and the temperature of the thermocouple can be read by a computer. In addition, the temperature on the mainboard of the electronic equipment can be directly read by a program in the electronic equipment. The actual temperature of the outer surface of the shell corresponds to the temperature of the main board temperature sensor according to a time relation, and then each coefficient value can be calculated by adopting a linear fitting mode.
When the program in the electronic device wants to acquire the temperature of the outer surface of the shell, a relatively accurate value can be obtained by calculating the coefficient value and the temperature of the mainboard temperature sensor.
However, temperature fitting needs to acquire enough data to fit accurate temperature parameters, and because the existing fitting original data depends on computer acquisition and electronic equipment acquisition, the fitting original data is limited to be acquired only in a laboratory environment in most cases, and the fitting parameters calculated through the data acquired in the laboratory can be inaccurate when being applied to an actual scene.
In the embodiment of the present application, an accurate coefficient can be obtained, specifically referring to fig. 3, and fig. 3 is a third schematic structural diagram of an electronic device provided in the embodiment of the present application. The electronic device 10 further includes a second temperature sensor 162 located in the housing 120, the second temperature sensor 162 is electrically connected to the processor 180, the processor 180 is configured to obtain a second temperature value acquired by the second temperature sensor 162, the processor 180 is further configured to calculate a conversion coefficient according to the first temperature value and the second temperature value, and the second temperature value can be calculated to obtain the first temperature value through the conversion coefficient.
The electronic device 10 may calculate a conversion coefficient between the first temperature sensor 160 and the second temperature sensor 162 during the test. When the electronic device 10 without the first temperature sensor 160 calculates the first temperature value of the outer surface 124 of the housing 120 accurately by the second temperature sensor 162 and the conversion coefficient in the housing 120. It should be noted that, in this embodiment, the obtaining of the conversion coefficient may be implemented without an additional computer or other electronic device 10, so that the electronic device 10 in this embodiment may not only obtain the conversion system through testing in a laboratory, but also obtain different conversion coefficients through testing in different scenarios, so as to obtain a plurality of conversion coefficients under multiple scenarios, multiple time periods, and multiple operating environments through testing, and store the plurality of conversion coefficients in the electronic device 10 to obtain a mapping table. For example, a conversion system corresponds to the outdoor environment, another conversion coefficient corresponds to the indoor environment, and for example, scenes such as walking, running, sitting on a subway, sitting on a bus, sitting on a train and the like all correspond to one conversion system, and a conversion coefficient can correspond to different operation environments of the electronic device 10 in different time periods in the same scene. It will be appreciated that the scenario, time period, and environment in which the electronic device 10 operates can be combined to provide a very large number of conversion systems, and that in various situations (scenario, time period, and environment) the first temperature value of the external surface 124 of the housing 120 can be accurately calculated from the second temperature sensor 162 within the electronic device 10. It is difficult to obtain such a large number of conversion factors from laboratory testing, or the conversion factors obtained from laboratory testing are in many cases inaccurate.
The quantity of second temperature sensor can be a plurality of, and a plurality of second temperature sensor intervals set up in the casing, and a plurality of second temperature sensor acquire a plurality of second temperature values, and a plurality of second temperature sensor all with treater electric connection, the treater is used for calculating according to first temperature value and a plurality of second temperature value and obtains a plurality of conversion coefficient, and wherein, each temperature sensor corresponds conversion coefficient, and a plurality of second temperature values calculate through a plurality of conversion coefficients and obtain first temperature value. The first temperature value obtained by calculation through one second temperature sensor and one conversion coefficient is easy to generate larger errors, and more accurate first temperature values can be obtained through a plurality of second temperature sensors at different positions in the electronic equipment and the conversion coefficient corresponding to each second temperature sensor. Meanwhile, the electronic equipment is prevented from being influenced by external factors, such as holding by a user, an interference heat source outside, shielding of the electronic equipment and the like, and the accuracy of the first temperature value can be prevented from being influenced by interference of single data through the plurality of second temperature sensors and the plurality of conversion coefficients.
The conversion coefficient can be obtained by calculating the first temperature value and the second temperature value in the embodiment, and other electronic equipment can be not provided with the through hole and can obtain the first temperature value of the outer surface of the shell by calculating the second temperature value and the conversion coefficient. In order to make the calculated first temperature value of other electronic devices more accurate, please continue to refer to fig. 1, the through hole 122 of the electronic device in this embodiment is spaced from the first temperature sensor 160. The through hole 122 is arranged at a distance from the first temperature sensor 160, heat in the shell 120 relative to the first temperature sensor 160 is not easily dissipated from the through hole 122, the environment of the electronic device with the through hole 122 is approximately the same as that of the electronic device without the through hole, the conversion coefficient obtained by testing and calculating the electronic device with the through hole 122 is also suitable for the electronic device without the through hole 122, the difference between the two electronic devices due to heat dissipation of the through hole 122 is avoided, and the first temperature value of the outer surface of the shell 120 obtained by calculating the conversion coefficient by the electronic device without the through hole is basically equal to the actual temperature value.

The connection line 140 is in interference fit with the through hole 122, there is no gap between the connection line 140 and the through hole 122, and the temperature inside the housing 120 and the temperature on the outer surface of the housing 120 are not or are not very different due to the through hole 122.
In order to facilitate the connection wire 140 to pass through the through hole 122, a gap is formed between the connection wire 140 and the through hole 122. Or it is difficult to seal the connection line 140 and the through hole 122, a filler 142 may be further disposed in the first through hole 122, and the filler 142 may fill a gap between the through hole 122 and the connection line 140. That is, the housing 120 includes a sidewall forming the through hole 122, and a filler 142 is further disposed in the first through hole 122, wherein the filler 142 fills a gap between the sidewall and the connection line 140. It is achieved that the temperature inside the housing 120, the temperature of the outer surface of the housing 120 are not or not very different by the through holes 122.
Wherein the thermal conductivity of the filler 142 is less than or equal to the thermal conductivity of the housing 120. Thus, the electronic device with the via 122 has the same or similar environment as the electronic device without the via 122, and the data tested by the electronic device with the via 122 is very close to the data of the electronic device without the via 122. The filling body 142 may be a material having elasticity, and after the connection line 140 passes through the gap between the filling bodies 142, the filling body 142 fills the gap between the connection line 140 and the sidewall. The filling body 142 may also be formed by colloid, that is, after the connecting wire 140 passes through the through hole 122, the through hole 122 is filled with colloid, and the filling body 142 is formed after the colloid is solidified.
The through-holes 122 may not need to be additionally provided, but may utilize existing through-holes 122, such as the through-holes 122 for mounting the case module, as shown in fig. 4. The through hole 122 can also be used for generating sound holes, as shown in fig. 5, the existing through hole 122 is fully utilized, and the obtained conversion coefficient is more effective when the electronic device has the same environment as the electronic device without the through hole 122, that is, the first temperature value obtained by calculating the second temperature value and the conversion coefficient is very close to the actual temperature, even the actual temperature is equal.
The connecting wire comprises an insulating protective layer, and the thermal conductivity of the protective layer is smaller than or equal to that of the shell. The thermal conductivity of the protective layer at the outermost layer of the connecting wire is less than or equal to that of the shell, so that the electronic equipment with the through hole has the same or similar environment with the electronic equipment without the through hole, and the data obtained by testing the electronic equipment with the through hole is very close to that of the electronic equipment without the through hole.
