Detailed Description
Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the example embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and thus a repetitive description thereof will be omitted.
As shown in fig. 1, an embodiment of the present invention discloses a control method for a notebook computer. The notebook computer comprises a palm rest area shell, a fan and a processor (namely a CPU). Fig. 2 shows, for example, the corresponding position of the palm rest area housing 21 of a notebook computer. The palm rest area housing 21 is used for realizing a hand rest function, that is, the palm rest area housing 21 is an area housing which plays a role in supporting a hand when a user uses a notebook computer. The shell parts of the notebook computer comprise an A shell (namely a screen rear cover), a B shell (namely a screen front frame), a C shell (namely a hand support position) and a D shell (namely a bottom shell). The C shell comprises the palm rest area shell. The bottom shell is the back shell of the notebook computer, namely the shell on one side which is contacted with the desktop when the notebook computer is placed on the desktop for use. The bottom shell is arranged opposite to the C shell, and the fan and the processor are arranged between the bottom shell and the C shell. The fan is mainly used for realizing the heat dissipation function of the notebook computer. The processor may control the rotational speed of the fan.
Referring to fig. 1, the notebook computer control method disclosed in the present embodiment includes the following steps:
s110, acquiring the ambient temperature of the notebook computer in the current working environment. Namely, the ambient temperature of the environment where the notebook computer is located is collected. In the specific implementation, a temperature sensor can be arranged on a PCB (printed circuit board) inside the notebook computer, and the temperature sensor independent of the notebook computer can also be adopted to realize the temperature acquisition of the surrounding environment. The invention is not limited in this regard.
And S120, acquiring the temperature of the palm rest area shell when the environmental temperature is lower than a first preset temperature threshold. That is, when the ambient temperature is lower than the corresponding threshold value, the temperature of the shell of the hand supporting area of the user is acquired, whether the rotation speed of the fan needs to be reduced or not is judged based on the temperature, so that the temperature of the CPU is increased, the whole temperature of the shell of the palm supporting area is driven to be increased, and the heating and hand warming functions of the shell of the hand supporting area are realized.
In the specific implementation, another temperature sensor can be arranged on the PCB inside the notebook computer, and the temperature of the palm support area shell can be directly collected. Or the temperature rise curve can be constructed and used for representing the temperature change condition of the processor and the palm support area shell along with the working time of the notebook computer respectively under an environment temperature, namely the temperature rise curve can represent the association relationship between the CPU temperature of the notebook computer and the palm support area shell temperature. Then the current temperature of the CPU can be directly read, and then the temperature of the palm support area shell is calculated through the temperature rise curve and the read CPU temperature. When the ambient temperature is higher than or equal to a first preset temperature threshold, the current working state of the notebook computer is maintained.
It should be noted that the above-mentioned temperature obtaining manner for the palm rest area housing is only exemplary, and other temperature obtaining manners adopted by those skilled in the art according to need are also within the scope of the present invention.
And S130, when the temperature of the palm rest area shell is lower than a second preset temperature threshold, reducing the rotating speed of the fan so as to increase the temperature of the processor. Specifically, when the temperature of the palm rest area shell is lower than the corresponding threshold, the temperature of the palm rest area shell in this case is indicated to have a relatively uncomfortable feeling for the user, such as the palm rest area shell is relatively cool in a cold environment. According to the invention, the rotating speed of the fan is reduced, so that the temperature of the CPU is increased, the whole temperature of the palm support area shell is driven to be increased, the hand warming function of heating the hand support area shell is realized, and the use experience of a notebook computer in a cold environment of a user is improved.
Alternatively, the upper limit value of the rotation speed of the fan may be reduced simultaneously with the reduction of the rotation speed of the fan. Therefore, the continuous regulation and control of the rotating speed of the fan can be kept according to the rotating speed upper limit value, the CPU is not required to execute the steps all the time to calculate the temperature of the current palm support area shell, the calculation efficiency of the control method is improved, and the calculation resources are saved. In other embodiments, the fan can be turned off to quickly raise the temperature of the CPU, thereby achieving the purpose of quickly warming hands, and further being beneficial to improving the use experience of the notebook computer in a cold environment for a user.
When the palm rest is in an environment of opening a heating or air conditioner, the temperature of the palm rest area shell can possibly meet the hand contact temperature requirement of a user; that is, the temperature of the palm support area shell is greater than or equal to the corresponding temperature threshold, the rotating speed of the fan is not required to be reduced under the condition, and the notebook computer can maintain the current working state.
In other embodiments, step S130 may further include: a speed reduction amplitude-temperature mapping table is pre-established, and the mapping table is used for representing the proper reduction amplitude of the corresponding fan under each temperature value of the palm rest area shell so as to reasonably reduce the speed of the fan according to the reduction amplitude value. Therefore, the balance between the stable rise of the temperature of the palm support area shell and the efficiency corresponding to the temperature threshold value can be achieved, the working performance of the notebook computer is ensured to meet the requirements of users, and the improvement of the use experience of users is further facilitated.
In other embodiments, the step S130 may further include: and when the temperature of the palm support area shell reaches a second preset temperature threshold value, recovering the rotating speed of the fan. I.e. to restore the fan speed to the pre-regulation temperature value. Specifically, the fan rotation speed is reduced from the third rotation speed value to the fourth rotation speed value in the above steps, for example. And when the temperature of the palm rest area shell reaches a second preset temperature threshold value, adjusting the rotating speed of the fan from the fourth rotating speed value to a third rotating speed value. The third rotation speed value is larger than the fourth rotation speed value.
The first preset temperature threshold may be 10 ℃ and the second preset temperature threshold may be 20 ℃, which is an example, but the present invention is not limited thereto, and those skilled in the art may set the temperature according to need.
In another embodiment of the present application, another notebook computer control method is disclosed. As shown in fig. 3, the method further includes the steps of:
s140, acquiring the current working temperature of the processor.
And S150, when the current working temperature of the processor is greater than a third preset temperature threshold, reducing the working power of the processor.
That is, when the temperature of the CPU of the notebook computer is too high, the self-protection function is started to reduce the working power of the CPU in view of the safety of the notebook computer, so that the safety of the CPU of the notebook computer is guaranteed. Alternatively, the CPU operating power may be restored to the pre-adjustment power after the CPU temperature is below the third preset temperature threshold.
The third preset temperature threshold may be, for example, 75 ℃, which is not limited to the present invention.
In another embodiment of the present invention, another notebook computer control method is disclosed. As shown in fig. 4, on the basis of the corresponding embodiment of fig. 1, the method further includes, before step S110:
s101, detecting the current user state and judging whether the user wears the earphone or not. When the earphone is worn, that is, the current user state is the state of wearing the earphone, step S102 is performed. When the earphone is not worn, that is, the current user state is the state of not wearing the earphone, step S103 is performed. The current user state is a state of wearing or not wearing the earphone. The detection of whether to wear the earphone may be implemented based on face recognition technology, which is not described in detail in this embodiment.
S102, setting the upper limit value of the rotation speed of the fan as a first rotation speed value.
S103, setting the upper limit value of the rotation speed of the fan as a second rotation speed value. Wherein the first rotation speed value is greater than the second rotation speed value.
That is, when the user does not wear the earphone, the upper limit value of the rotation speed of the fan is reduced due to the consideration of noise influence caused by rotation of the fan, so that the rotation speed of the fan under the condition of high rotation speed can be reduced, and the notebook computer using experience of the user under the scene of not wearing the earphone can be improved. When the user wears the earphone, the upper limit value of the rotating speed of the fan can be increased, so that the notebook computer working performance is improved under the condition that the noise experience of the user is not affected, and the use experience of the notebook computer is improved.
In this embodiment, in step S101, the environmental noise and the fan noise may be acquired first, and when the fan noise is greater than the environmental noise, the current user state is detected to determine whether the user wears the earphone. Wherein the ambient noise may be acquired by a microphone sensor acquisition. The fan noise can be matched with the pre-established fan rotating speed-noise mapping table according to the read fan rotating speed and the mapping table to obtain the corresponding fan noise. Therefore, frequent starting of the microphone and the camera can be avoided, and the experience of a user in the process of using the notebook computer can be improved.
Optionally, for the step of acquiring the environmental noise and the fan noise, the fan noise may be acquired first, and when the fan noise is greater than the corresponding noise threshold, the environmental noise and the fan noise are acquired and compared, so that frequent opening of the microphone and the camera can be avoided, and the experience of the user in the process of using the notebook computer is facilitated.
In an alternative embodiment, the notebook computer further includes a power management chip, a thermoelectric generation chip, a heat dissipation tube, and a bottom case based on the corresponding embodiment of fig. 1. The power management chip is used for supplying power to the electric elements in the notebook computer. The power management chip is electrically connected with the thermoelectric generation chip. The thermoelectric generation piece is arranged between the radiating pipe and the bottom shell. The radiating pipe is arranged on one side of the CPU processor, which is away from the palm support area shell. That is, along the direction that the C shell points to the D shell (bottom shell), the C shell, the PCB board, the CPU processor, the radiating pipe, the thermoelectric generation piece and the bottom shell are sequentially arranged.
Based on the embodiment, through the control of the rotation speed of the fan and the power consumption of the CPU, the temperature of the user contact surface, namely the palm support area shell, is increased to obtain a proper range of user body feeling, so that the temperature difference between the CPU surface and the bottom shell is maximized, the temperature difference power generation technology of the temperature difference power generation piece is utilized to generate power, and the power generated by the temperature difference power generation piece can be fed back to the power management chip through the voltage stabilizing device, so that the battery of the notebook computer is not charged. Therefore, when the fan is cooled, heat of the CPU is effectively recovered, waste is avoided, and the use experience is improved.
In an alternative embodiment, the notebook computer further includes an extension tube and a heat dissipation tube located at the back on the basis of the corresponding embodiment of fig. 1. The first end of the extension tube is connected with the radiating tube, and the second end of the extension tube is bent to the user contact surface of the notebook computer to be connected with the palm support area shell to form a radiating channel. Therefore, the design of the extension tube can be realized, the heat of the CPU is sequentially connected to the user contact surface through the radiating tube and the extension tube, the palm support area shell can be assisted to heat and warm hands, and the use experience of a user is further improved.
Based on the embodiment of the extension tube design, as shown in fig. 5, another embodiment of the present invention discloses another notebook computer control method. In this embodiment, the notebook computer further includes a keyboard base. Referring to fig. 2, the keyboard base includes a key area 22, a touch area 23, and palm rest areas located at two sides of the touch area. The heat dissipation channels comprise first heat dissipation channels arranged at two ends of the keyboard base in the length direction and second heat dissipation channels arranged between the first heat dissipation channels. The use mode of the notebook computer is a leg support mode or a desktop support mode.
As shown in fig. 5, the control method provided in this embodiment further includes, on the basis of including the steps S110 to S130 described above, the steps of:
s160, judging whether the using mode of the notebook computer is a leg supporting mode. If yes, go to step S170. If not, that is, if the usage mode is the desktop supporting mode, step S180 is performed.
S170, controlling the first heat dissipation channel to be closed and controlling the second heat dissipation channel to be opened.
S180, controlling the first heat dissipation channel and the second heat dissipation channel to be opened.
That is, when the temperature of the palm rest area housing is lower than a second preset temperature threshold and the use mode of the notebook computer is detected to be the leg support mode, the first heat dissipation channel is controlled to be closed and the second heat dissipation channel is controlled to be opened. And when the temperature of the palm support area shell is lower than a second preset temperature threshold value and the use mode of the notebook computer is detected to be a desktop supporting mode, controlling the first heat dissipation channel and the second heat dissipation channel to be opened.
In particular, in this embodiment, the bottom case of the notebook computer is provided with a plurality of pressure sensors. When the pressure values detected by the pressure sensors are within a preset interval, namely the detected pressure values at all positions have smaller differences, the using mode of the notebook computer can be determined to be a desktop supporting mode. Otherwise, determining the using mode of the notebook computer to be a leg supporting mode. And when the detected pressure values at all the positions have larger differences, determining the using mode of the notebook computer as a leg supporting mode. This is because there is a significant difference between the pressure on the bottom case of the notebook computer for the leg support position and the pressure on the position not supported by the legs when in the leg support mode.
According to the embodiment, when a user uses the notebook computer on the legs for office work and the environment temperature is low, the radiating channel above the legs can be mainly opened, so that radiating heat mainly passes through the upper sides of the legs, the effect of heating the legs below the bottom shell can be achieved on the basis of heating the palm supporting area shell for warming hands, and the user experience of using the notebook computer for office work on the legs can be further improved. Further alternatively, the heat dissipation channels at the positions corresponding to the positions with the detected larger bottom shell pressure values (for example, the positions with the detected larger bottom shell pressure values are larger than a preset pressure threshold value) can be opened, and the heat dissipation channels at other positions are closed. The user can work on the legs by using the notebook computer, and experience is further improved.
On the basis that the palm holds in palm regional casing and realizes heating warm hand, avoid the user to use the not good problem of experience when the notebook computer drain pan high temperature brings when working on the leg like this, further do benefit to the experience that improves the user and use notebook computer in-process.
