Detailed Description
The purpose of this application lies in realizing the intellectual detection system to notebook computer current user state to know the notebook computer can automatically regulated control by temperature change strategy when the user official working on the leg, avoided notebook computer's drain pan high temperature's problem.
The hardware structure of the notebook computer provided by the present application is described in detail below with reference to the accompanying drawings. The following embodiments may be combined with each other, and the description of the same or similar contents in different embodiments will not be repeated.
Fig. 1 is a schematic structural diagram of a notebook computer according to an embodiment of the present application. As shown in fig. 1, the notebook computer provided in this embodiment includes:
the pressure detection device 11 includes a plurality of pressure sensing devices, and the plurality of pressure sensing devices are disposed at different positions of a bottom plate of the notebook computer.
And the controller 12 is connected with the pressure detection device 11 and is used for determining the current use mode of the notebook computer according to the bottom plate pressure data acquired from the pressure detection device and starting corresponding temperature control processing according to the use mode.
Wherein the use mode comprises a leg-on mode or a table-on mode.
Specifically, the controller 12 may obtain pressure values or pressure change values of the multiple pressure sensing devices from the pressure detection device 11, may be actively obtained by the controller 12, or may be actively reported by the pressure detection device 11, and this embodiment is not limited in any way. For example, when the pressure detection device 11 determines that the pressure value of at least one pressure sensing device exceeds the preset pressure threshold, or the pressure variation value exceeds the preset pressure variation threshold, the pressure detection device 11 actively reports the pressure value and the position of the pressure sensing device corresponding to the pressure value on the base plate to the controller 12, or reports the pressure variation value and the position of the pressure sensing device corresponding to the pressure variation value on the base plate.
In the present application, the use mode of the notebook computer includes a leg-up mode or a desk-up mode. The on-leg mode is an unconventional use mode of the notebook computer, and means that a user places the notebook computer on the leg to do office or entertainment activities and the like. The desktop mode is a normal use mode of the notebook computer, and means that a user places the notebook computer on an object with a flat surface (such as a desk, a dining table, a chair, and the like) to perform activities such as office work or entertainment.
In this embodiment, different temperature control processes can be set for the usage mode of the notebook computer. It will be appreciated that the temperature control process is more stringent in the leg rest mode than in the desk top mode. For example, the temperature control process for the desktop mode may include controlling the fan to rotate at a first rotational speed, and the temperature control process for the leg mode may include controlling the fan to rotate at a second rotational speed and reducing a portion of the device performance (e.g., reducing the performance of the processor), where the second rotational speed is greater than the first rotational speed. When the notebook computer detects that the use mode of the user is changed, for example, the notebook computer is switched from the leg-mounted mode to the desk-mounted mode, the controller can execute corresponding temperature control processing.
The pressure sensing device comprises at least one of the following components:
piezoelectric ceramic plates; a pressure strain gauge; a MEMS pressure sensor.
The piezoelectric ceramic piece is an electronic sound generating element and has a piezoelectric effect, and the piezoelectric effect has reversibility: if voltage is applied to the piezoelectric ceramic chip, mechanical vibration can be generated, and sound is produced; on the contrary, when the piezoelectric ceramic piece is subjected to mechanical pressure, a certain amount of charges Q can be generated on the piezoelectric ceramic piece, and a voltage signal can be output.
It should be noted that the present embodiment utilizes a positive piezoelectric effect (mechanical effect is converted into an electrical effect), that is, the second case of the piezoelectric effect described above. When external pressure is applied to the piezoelectric ceramic piece, the two ends of the piezoelectric ceramic piece can generate a discharge phenomenon, and on the contrary, when external tension is applied to the piezoelectric ceramic piece, the two ends of the piezoelectric ceramic piece can generate a charge phenomenon.
The pressure strain gauge works based on the principle of resistance strain effect, and the resistance strain gauge includes a metal strain gauge (metal wire or metal foil) and a semiconductor strain gauge. The metal conductor or semiconductor material can generate mechanical deformation under the action of mechanical external force, and the resistance value of the metal conductor or semiconductor material changes correspondingly. When the strain gauge generates compressive strain, the resistance value of the strain gauge is reduced; when the strain gauge generates tensile strain, the resistance value of the gauge increases. The change in resistance can be known by the detection circuit.
A MEMS pressure sensor is a thin film element that deforms when subjected to pressure. This deformation can be measured using strain gauges (piezoresistive sensing) or by capacitance sensing of the change in distance between two faces. Based on the difference of sensing principles, the MEMS pressure sensor includes at least one of:
a capacitive pressure sensor; a resonant pressure sensor; a piezoresistive pressure sensor.
Different types of pressure sensors can be selected according to actual requirements, and the embodiment is not limited in any way.
It should be understood that after the type of the pressure sensing device is selected, the types of the plurality of pressure sensing devices provided in the notebook computer should be identical.
Based on the above description, the spatial layout of the multiple pressure-sensing devices in the embodiment of the present application is described below with reference to fig. 2.

Of course, the pressure sensing device may be disposed at the center of the short side direction of the inner side edge of the bottom plate of the notebook computer (not shown in the figure).
As shown in fig. 2 (c), the number of the pressure sensing devices may be three, and the pressure sensing devices may be disposed at equal intervals in a longitudinal direction (7, 8, and 9 in the drawing) passing through the center of the bottom plate inside the bottom plate of the notebook computer.
As shown in fig. 2 (d), the number of the pressure sensing devices is still six, and the pressure sensing devices may be disposed at equal intervals in two parallel long side directions (10, 11, 12 and 13, 14, 15 in the figure) inside the bottom plate of the notebook computer.

On the basis of the above embodiments, the following embodiments further refine the specific structure of the pressure detection device. For different types of pressure sensing devices, the internal structures of the pressure detecting devices are different, but the implemented functions are the same, and the hardware structure of the notebook computer according to the embodiment of the present application is described below with reference to fig. 3 to 6.

As shown in fig. 3, the notebook computer provided in this embodiment includes: a pressure detection device 11 and a controller 12. The pressure detection device 11 includes a plurality of pressure sensing devices and a pressure detection driving device. The pressure sensing devices are connected with the controller through the pressure detection driving device.

In some embodiments, the pressure detection driving device may include a detection circuit and a driving chip disposed on a driving board, may also include a detection circuit and an a/D conversion chip disposed on a driving board, and may also include a detection circuit and a voltage amplification circuit disposed on a driving board. The driving board may be disposed on a printed circuit board (i.e., a motherboard) of the notebook computer, or may be disposed between the bottom board and the keyboard as a separate printed circuit board (i.e., a small board).
For different types of pressure sensing devices, the pressure sensing devices can be connected with the controller through the pressure detection driving device shown in fig. 3. For example, fig. 4 shows a schematic structural diagram of a notebook computer in which the pressure sensing device is a piezoelectric ceramic plate, as shown in fig. 4, a plurality of piezoelectric ceramic plates are connected to the controller through the detection circuit and the driving chip, and n is a positive integer greater than or equal to 2. The detection circuit and the driving chip can be arranged on the pressure detection driving plate.

The controller 12 may read the pressure value or pressure change value in the driving chip through the I2C interface or other bus interface in real time. Or the driving chip informs the controller to read the pressure value or the pressure change value when the pressure value is determined to exceed the preset pressure threshold value or the pressure change value exceeds the preset pressure change threshold value.

The pressure detection device 11 is used for detecting the pressure data of the bottom plate of the notebook computer, the inertia detection device 13 is used for detecting the pose information (position information and pose information) of the notebook computer, and the controller 12 is used for determining the current use mode of the notebook computer according to the pressure data of the bottom plate and the pose information and starting corresponding temperature control processing according to the use mode. The use modes comprise a leg-on mode or a table-on mode, and different use modes correspond to different temperature control treatments.
In the present embodiment, the inertia detecting means may be an acceleration sensor, an angular velocity sensor, or a combination of both sensors. An acceleration sensor (G-sensor) generally comprises a mass block, a damper, an elastic element, a sensing element, an adaptive circuit and other components, wherein the acceleration sensor obtains an acceleration value by measuring an inertial force applied to the mass block in an acceleration process according to a newton second law, and common acceleration sensors include a capacitance type, an inductance type, a strain type, a piezoresistive type, a piezoelectric type and the like according to different sensing elements of the sensor. The angular velocity sensor (or called gyroscope) is used for measuring the rotation angular velocity of the terminal when the terminal deflects and tilts. For example, in a notebook computer, it is impossible to measure or reconstruct the 3D motion (attitude information) of the notebook computer only by using an acceleration sensor, the acceleration sensor can only detect the linear motion in the axial direction of the notebook computer, and the angular velocity sensor can detect the motions such as rotation and deflection of the notebook computer.
In this embodiment, the controller of the notebook computer may determine the current usage mode of the notebook computer by combining the detection data of the pressure detection device and the inertia detection device, and start the corresponding temperature control process according to the usage mode. For example, when the controller determines that the use mode of the notebook computer is switched, for example, the desktop mode is switched to the leg mode, the controller may automatically start the temperature control processing corresponding to the leg mode. Compared with the embodiment shown in fig. 1, the notebook computer provided by the embodiment of the invention can detect the usage mode more accurately.
The notebook computer that this application embodiment provided, including pressure detection device, inertia detection device and controller, wherein pressure detection device includes a plurality of pressure-sensitive devices, and a plurality of pressure-sensitive devices, inertia detection device are connected with the controller respectively. The pressure detection device is used for detecting bottom plate pressure data of the notebook computer, the inertia detection device is used for detecting pose information of the notebook computer, the controller is used for determining a current use mode of the notebook computer according to the bottom plate pressure data and the pose information, and when the use mode is switched, for example, the desktop mode is switched to the leg mode, corresponding temperature control processing of the leg mode is automatically started, so that intelligent detection and control of the use mode of the notebook computer are realized, and the problem that the temperature of a bottom plate of the notebook computer is too high when a user works on the legs is avoided.
Fig. 8 is a schematic structural diagram of a notebook computer according to yet another embodiment of the present application. As shown in fig. 8, the notebook computer provided in this embodiment includes: a pressure detection device 11, a human-computer interaction detection device 14 and a controller 12. The pressure detection device 11 comprises a plurality of pressure sensing devices, and the plurality of pressure sensing devices are connected with the controller 12; the human interaction detection device 14 is connected to the controller 12.

The controller can read the touch information of the user on the keyboard and/or the touch pad through the KSI/KSO interface.
It should be understood that there is a difference between the touch information corresponding to the desktop mode and the leg mode. For example, when the user inputs the same content through the keyboard, the sequence and the position of the user clicking the keyboard keys are the same, and if the use mode is the desktop mode, the knocking strength of each key is relatively uniform (that is, the knocking strength of each key is basically the same); if the use mode is the leg-on mode, the knocking force of each key is uneven due to the uneven supporting surface of the notebook computer. Therefore, the controller can determine the current use mode of the notebook computer according to the knocking strength of each key detected by the man-machine interaction detection device. For another example, when the user performs a sliding operation on the touch pad, if the usage mode is a desktop mode, the pressure values of the touch points at each time point in the sliding operation are relatively uniform (i.e., the pressure values of the touch points in the sliding process are substantially the same); if the use mode is the leg-on mode, the pressure value of the touch point at each moment in the sliding operation is not uniform due to the uneven supporting surface of the notebook computer. Therefore, the controller can determine the current use mode of the notebook computer according to the pressure value of each touch point in the sliding operation detected by the human-computer interaction detection device.
In this embodiment, the controller of the notebook computer may determine the current usage mode of the notebook computer by combining the detection data of the pressure detection device and the human-computer interaction detection device, and start corresponding temperature control processing according to the usage mode. For example, when the controller determines that the use mode of the notebook computer is switched, for example, the desktop mode is switched to the leg mode, the controller may automatically start the temperature control processing corresponding to the leg mode. Compared with the embodiment shown in fig. 1, the notebook computer provided by the embodiment of the invention can detect the usage mode more accurately.
