Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The term "and/or" is herein merely an association relationship describing an associated object, meaning that there may be three relationships, e.g., a and/or B, may represent: a exists alone, A and B exist together, and B exists alone.
The terms first and second and the like in the description and in the claims of embodiments of the application, are used for distinguishing between different objects and not necessarily for describing a particular sequential order of objects. For example, the first target object and the second target object, etc., are used to distinguish between different target objects, and are not used to describe a particular order of target objects.
In embodiments of the application, words such as "exemplary" or "such as" are used to mean serving as an example, instance, or illustration. Any embodiment or design described herein as "exemplary" or "e.g." in an embodiment should not be taken as preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete fashion.
In the description of the embodiments of the present application, unless otherwise indicated, the meaning of "a plurality" means two or more. For example, the plurality of processing units refers to two or more processing units; the plurality of systems means two or more systems.
When using a smart terminal (such as a tablet computer), an input device is generally used to improve input efficiency and input accuracy. The input device includes, for example, a keyboard, a stylus, and the like. The keyboard (also referred to as a keyboard protective cover) may include, for example: the keyboard comprises a keyboard main body part and a supporting part, wherein the keyboard main body part is connected with the supporting part. The support part is provided with a connecting module (such as pogo pin) electrically connected with the tablet personal computer, and the keyboard main body part is provided with keys, a touch pad and the like for user operation. When the keyboard is used, the connecting module (such as pogo pin) of the tablet computer is electrically connected with the connecting module on the supporting part, so that the keyboard is electrically connected with the tablet computer, and further, electric energy transmission and/or data transmission are realized; meanwhile, the supporting part can support the tablet personal computer. When the tablet personal computer is stored, the tablet personal computer is clamped between the supporting part and the keyboard main body part, and the tablet personal computer can be protected.
To ensure the effectiveness of the power transfer and/or data transmission between the tablet computer and the keyboard, a first hall device (also called hall sensor) is generally disposed in the tablet computer and near the connection module, and correspondingly, the keyboard is disposed with a first magnet at the location where the connection module is disposed, where the first magnet is opposite to the first hall device when the connection module of the tablet computer contacts the connection module on the keyboard. Whether the connection module of the tablet computer and the connection module of the keyboard are successfully connected or not is detected through the magnetic field intensity detected by the first Hall device, electric energy transmission can be carried out between the tablet computer and the keyboard only when the connection module of the tablet computer and the connection module of the keyboard are successfully connected, so that the situation of electric leakage is prevented, and/or data transmission can be carried out between the tablet computer and the keyboard, so that the failure of data transmission is prevented. The specific principle that whether the connection module of the tablet personal computer and the connection module of the keyboard are successfully connected is that the magnetic field intensity detected by the first Hall device is used for detecting whether the connection module of the tablet personal computer and the connection module of the keyboard are successfully connected or not is that the first Hall device is provided with a first threshold value (the first threshold value is determined before delivery and cannot be adjusted in the using process), the first magnet is close to the first Hall device, the magnetic field intensity detected by the first Hall device is increased, when the magnetic field intensity exceeds the first threshold value, the first Hall device sends a trigger signal to a processing module in the electronic equipment, and the processing module can determine that the connection module of the tablet personal computer and the connection module of the keyboard are successfully connected according to the trigger signal.
In addition, some intelligent terminals (such as tablet computers or mobile phones) combine the opening or closing of a keyboard with the on-screen and off-screen of the intelligent terminal. For example, when the keyboard is covered on the display screen of the tablet computer, the screen of the tablet computer is turned off, and when the keyboard is taken off from the display screen of the tablet computer, the screen of the tablet computer is lightened.
The bright screen and the screen-off detection of the intelligent terminal are realized through the Hall device. The second hall device is disposed in the tablet computer, for example, at an edge of an outer contour of the tablet computer, and the second magnet is disposed at a portion of the keyboard cover on the display screen of the tablet computer, for example, opposite to the second hall device when the keyboard cover is on the display screen of the tablet computer. Whether the keyboard is covered on the display screen of the tablet personal computer is detected through the magnetic field intensity detected by the second Hall device, and then the display screen is controlled to be turned off or on, wherein when the keyboard is covered, the distance between the second magnet and the second Hall device is short, the magnetic field intensity detected by the second Hall device is large, and when the keyboard is opened, the distance between the second magnet and the second Hall device is long, and the magnetic field intensity detected by the second Hall device is small. The specific principle that whether the keyboard is covered on the display screen of the tablet personal computer is detected through the magnetic field intensity detected by the second Hall device is that the second Hall device is provided with a second threshold value (the threshold value is determined before delivery and cannot be adjusted in the use process), when the second magnet approaches to the second Hall device, the magnetic field intensity detected by the second Hall device is increased, when the magnetic field intensity exceeds the second threshold value, the second Hall device sends a trigger signal to a processing module in the electronic equipment, the processing module can determine that the keyboard is covered on the display screen of the tablet personal computer according to the trigger signal, when the magnetic field intensity does not exceed the second threshold value, the second Hall device does not send the trigger signal to the processing module in the electronic equipment, and the processing module determines that the keyboard is not covered on the display screen of the tablet personal computer.
That is, when the tablet computer matches the keyboard to realize pogo pin connection detection and detection of whether the keyboard is covered on the display screen, two hall devices must be set (because only one hall device is provided, the hall device only has one threshold value, that is, only can realize pogo pin connection detection or detection of whether the keyboard is covered on the display screen, and can not realize pogo pin connection detection and detection of whether the keyboard is covered on the display screen at the same time), and the two hall devices result in higher cost of the electronic device, occupy larger internal space of the electronic device, and are unfavorable for setting of other structures.
Based on the above, the embodiment of the application provides an electronic device, in which a magnetometer is arranged, and because the magnetometer has the characteristics of size and direction, the magnetic field intensity components in different directions can be detected, so when the positions of the magnets on the keyboard are different, the detected magnetic field intensities are different, and the detection type is determined according to the different magnetic field intensities. Therefore, the dual functions of pogo pin disconnection detection and detection of whether the keyboard is covered on the display screen can be realized through a single magnetometer. Because single magnetometer compares in a plurality of hall devices, with low costs, and occupy electronic equipment inner space less, consequently, can realize reducing electronic equipment's cost to and reduce the effect that occupies electronic equipment inner space.
The electronic device provided by the embodiment of the application can be a tablet personal computer, a mobile phone, a computer, a personal digital assistant (personal digital assistant, PDA for short), a vehicle-mounted computer, a television, an intelligent wearable device, an intelligent home device and the like, and the specific form of the electronic device is not particularly limited.
The specific structure of the electronic device according to the embodiment of the present application is described below. The following examples are all described with the electronic device being a tablet computer.

Referring to fig. 3, fig. 3 is a schematic diagram of axial data of a magnetometer according to an embodiment of the application. As shown in FIG. 3, magnetometer 60 has the size and orientation characteristics that allows the detection of magnetic field strength components in different directions, i.e., the detection of magnetic field strength in three dimensions (X-axis, Y-axis, and Z-axis) based on the magnetic field around it. The screen printing surface is, for example, a surface perpendicular to the Z axis and located on the +z axis in magnetometer 60, i.e., the surface marked with AA in fig. 3. The surface opposite to the screen printed surface is provided with solder balls by which the magnetometer 60 is soldered to the PCB 40 and an electrical connection is made to the PCB 40. It should be noted that, the PCB 40 includes a first surface 41 and a second surface 42 opposite to each other, and fig. 3 illustrates that the magnetometer 60 is disposed on the first surface 41 of the PCB 40, but the present application is not limited thereto, and in other alternative embodiments, the magnetometer 60 may be disposed on the second surface 42. It will be appreciated that whether magnetometer 60 is disposed on first surface 41 or second surface 42, bottom surface 61 thereof is in contact with PCB 40.
It will be appreciated that when the magnetometer 60 is disposed on the first surface 41 of the PCB 40, the magnetic field strength detected by the magnetometer 60 is positive when a magnet is located at the position of the display screen 10, i.e. at the position of the magnetometer 60 in the +z-axis direction; when a magnet is located at the position of the rear case 30, i.e., at the position of the magnetometer 60 in the-Z axis direction, the intensity of the magnetic field detected by the magnetometer 60 is negative. When the magnetometer 60 is disposed on the second surface 42, the intensity of the magnetic field detected by the magnetometer 60 is negative when a magnet is located at the position of the display screen 10, i.e., at the position of the magnetometer 60 in the-Z axis direction; when a magnet is located at the position of the rear case 30, that is, at the position of the +z-axis direction of the magnetometer 60, the magnetic field intensity detected by the magnetometer 60 is positive.

Referring to fig. 4, fig. 4 is a circuit diagram of an electronic device according to an embodiment of the present application. As shown in fig. 4, the tablet computer 100 further includes an external memory interface 120, an internal memory 121, a universal serial bus (universal serial bus, USB) interface 130, a charge management module 140, a power management module 141, a battery 142, an antenna 1, an antenna 2, a mobile communication module 150, a wireless communication module 160, an audio module 170, a speaker 170A, a receiver 170B, a microphone 170C, an earphone interface 170D, a sensor module 180, a key 190, a motor 191, an indicator 192, a camera 193, and a user identification module (subscriber identification module, SIM) card interface 195, an external interface 70, a switching circuit 80, and a processing module 90, wherein the external interface 70 may be, for example, an interface different from the USB interface 130, and the sensor module 180 may include the magnetometer 60 described above.
The external interface 70 is electrically connected with the processing module 90 through the switch circuit 80, the magnetometer 60 is also electrically connected with the processing module 90, and the processing module 90 can receive the magnetic field intensity detected by the magnetometer 60.
The external interface 70 enables the tablet pc 100 to be coupled with an external device (such as the input device described above), so as to implement data interaction and/or power transfer between the tablet pc 100 and the external device.
The USB interface 130 is an interface conforming to the USB standard specification, and may specifically be a Mini USB interface, a Micro USB interface, a USB Type C interface, or the like. The USB interface 130 may be used to connect a charger to charge the electronic device 100, and may also be used to transfer data between the electronic device 100 and a peripheral device. And can also be used for connecting with a headset, and playing audio through the headset. The interface may also be used to connect other electronic devices, such as AR devices, etc.
It should be understood that the tablet computer 100 shown in fig. 4 is only one example of a tablet computer, and that the tablet computer 100 may have more or fewer components than shown in the figures, may combine two or more components, or may have a different configuration of components. The various components shown in fig. 4 may be implemented in hardware, software, or a combination of hardware and software, including one or more signal processing and/or application specific integrated circuits.
For example, referring to fig. 5, fig. 5 is one of application scenarios of an electronic device provided in an embodiment of the present application. As shown in fig. 5, tablet 100 is coupled to keyboard 200 through external interface 70. The keyboard 200 may include, for example: a support portion 210 and a keyboard main body portion 220, the keyboard main body portion 220 being connected to the support portion 210.
Referring to fig. 6 and fig. 7, fig. 6 is a schematic diagram of a back structure of a tablet pc according to an embodiment of the present application, and fig. 7 is a schematic diagram of a keyboard according to an embodiment of the present application. As shown in fig. 6 and fig. 7, the external interface 70 of the tablet pc 100 may be, for example, a pogo-pin, which is disposed on the rear surface of the tablet pc 100, and correspondingly, a pogo-pin is also disposed on the supporting portion 210 of the keyboard 200 for placing the tablet pc 100, where the pogo-pin of the external interface 70 is, for example, a male pogo-pin, and the pogo-pin disposed on the keyboard 200 is a female pogo-pin. In use (as shown in fig. 5), the female pogo-pin of the keyboard 200 is in contact with the male pogo-pin of the tablet computer 100, so that the keyboard 200 can be electrically connected with the tablet computer 100; meanwhile, the supporting part 210 can support the tablet pc. When stored (as shown in fig. 8), the tablet pc 100 is sandwiched between the support portion 210 and the keyboard main body portion 220, so that the tablet pc 100 can be protected.
In order to reduce the number of pins exposed to the outside of the pogo-pin and thus make the appearance of the tablet pc 100 more attractive, the male pogo-pin includes three pins, which are the data transmission pin 71, the power pin 72 and the ground pin 73, for example. Correspondingly, the female pogo pin of the keyboard 200 also comprises three pins, namely a data transmission pin 201, a power pin 202 and a ground pin 203. Referring to fig. 9, fig. 9 is a partial circuit diagram of an electronic device according to an embodiment of the present application, as shown in fig. 9, three pins of a female pogo pin are in one-to-one correspondence with three pins on a male pogo pin (a data transmission pin 11 is in contact with a data transmission pin 201, a power supply pin 12 is in contact with a power supply pin 202, and a ground pin 13 is in contact with a ground pin 203), so as to realize electrical connection between a tablet pc 100 and a keyboard 200.
The above example is described by taking the pogo pin provided on the rear surface of the tablet pc 100 as an example, but the present application is not limited thereto. In other alternative embodiments, the pogo pin may also be located on the middle frame of the tablet pc 100, and accordingly, the position of the pogo pin in the keyboard 200 needs to be changed correspondingly, for example, the pogo pin is disposed on the keyboard body 220, so as to adapt to the position of the pogo pin of the tablet pc 100, and further facilitate connection.
In order to cooperate with the magnetometer 60 to simultaneously realize the pogo pin disconnection detection and the detection of whether the keyboard is covered on the display screen, a first magnet is provided on the support portion 210 of the keyboard 200, and a second magnet is provided on the keyboard main body portion 220 of the keyboard 200.
The principle of implementing pogo pin disconnection detection and detection of whether a keyboard is covered on a display screen by combining the structure is described below.
From the foregoing, it will be appreciated that the magnetometer 60 has the size and direction characteristics that it is possible to detect the magnetic field intensity components in different directions, i.e., it is possible to detect the magnetic field intensity in three dimensions (X-axis direction, Y-axis direction, and Z-axis direction) based on the magnetic field around it, and it is possible to send the detected magnetic field intensity to the processing module 90 in real time, without being limited to a threshold value. Because the first magnet and the second magnet are located at different positions of the keyboard, the magnetic field strength detected by the magnetometer 60 is different when the first magnet is close (i.e., the female end pogo-pin of the keyboard 200 is connected to the male end pogo-pin of the tablet 100), the second magnet is close (i.e., the keyboard body 220 is overlaid on the display 10), or the first magnet and the second magnet are close together (i.e., the female end pogo-pin of the keyboard 200 is connected to the male end pogo-pin of the tablet 100 and the keyboard body 220 is overlaid on the display 10). Correspondingly, the corresponding relation between the preset magnetic field intensity range and the working state of the electronic device is stored in the processing module 90, wherein the corresponding relation between the preset magnetic field intensity range and the working state of the electronic device at least comprises that the first preset magnetic field intensity range corresponds to the external interface being in the power-on state, the second preset magnetic field intensity range corresponds to the external interface being in the power-on state and the display screen of the electronic device being in the screen-off state, and the third preset magnetic field intensity range corresponds to the display screen of the electronic device being in the screen-off state. The processing module 90 can collect the magnetic field strength detected by the magnetometer 60 in real time, compare the magnetic field strength with a preset magnetic field strength range, and further control the working state of the electronic device, where the working state includes a first state, a second state and a third state, the first state is that the external interface is in a power-on state, the second state is that the external interface is in a power-on state and the display screen of the electronic device is in a screen-off state, and the third state is that the display screen of the electronic device is in a screen-off state
When the magnetic field strength collected by the processing module 90 is within the first preset magnetic field strength range, it indicates that the female end pogo-pin of the keyboard 200 is connected with the male end pogo-pin of the tablet pc 100, and the requirement of powering on the external interface is needed at this time, so based on this, the processing module 90 controls the control switch circuit 80 to be turned on for electric energy transmission and/or data interaction. When the magnetic field intensity collected by the processing module 90 is within the second preset magnetic field intensity range, it indicates that the female end pogo-pin of the keyboard 200 is connected with the male end pogo-pin of the tablet pc 100 and the keyboard main body 220 is covered on the display screen 10, and at this time, the requirement of powering on and off the external interface is needed, so based on this, the processing module 90 controls the switch circuit 80 to be turned on for electric energy transmission and/or data interaction, and controls the display screen 10 to be turned off. When the magnetic field intensity collected by the processing module 90 is within the third preset magnetic field intensity range, it indicates that the keyboard main body 220 is covered on the display screen 10, and at this time, there is a screen-off requirement, so the processing module 90 controls the display screen 10 to be turned off based on the requirement.
It should be noted that, the correspondence between the pre-stored magnetic field intensity range and the working state of the electronic device may be obtained through verification in the early test. For example, in the early test, when the support portion contacts the back surface of the tablet computer, that is, when the first magnet approaches the magnetometer, the magnetometer may detect a magnetic field strength, so as to avoid the influence caused by signal fluctuation, a magnetic field range may be determined based on the magnetic field strength, and the range may be stored in the processing module 90, where the magnetic field range is the first preset magnetic field strength range. When the keyboard main body portion is covered on the display screen of the tablet computer and the supporting portion is in contact with the rear shell surface of the tablet computer, namely, the first magnet and the second magnet are simultaneously close to the magnetometer, the magnetometer can detect a magnetic field intensity, in order to avoid the influence caused by signal fluctuation, a magnetic field range can be determined based on the magnetic field intensity, and the range is stored in the processing module 90, and the magnetic field range is the second preset magnetic field intensity range. When the keyboard main body portion is covered on the display screen of the tablet computer, that is, when the second magnet approaches the magnetometer, the magnetometer detects a magnetic field intensity, in order to avoid the influence caused by signal fluctuation, a magnetic field range can be determined based on the magnetic field intensity, and the range is stored in the processing module 90, and the magnetic field range is the third preset magnetic field intensity range.
It will be appreciated that the orientation of the magnets during the early test should be consistent with the orientation of the magnets during later use. For example, in the early test, the first preset magnetic field intensity range, the second preset magnetic field intensity range and the third preset magnetic field intensity range are determined based on the approach or the separation of the N pole of the first magnet to the magnetometer and the approach or the separation of the N pole of the second magnet to the magnetometer, and then in the later use, the N pole of the first magnet and the N pole of the second magnet are required to be arranged to be opposite to the magnetometer.
In the early test, the S pole of the first magnet and the S pole of the second magnet are required to be arranged to be opposite to the magnetometer when the S pole of the first magnet approaches or departs from the magnetometer and the S pole of the second magnet approaches or departs from the magnetometer to determine the first preset magnetic field intensity range, the second preset magnetic field intensity range and the third preset magnetic field intensity range. In the early test, the first preset magnetic field intensity range, the second preset magnetic field intensity range and the third preset magnetic field intensity range are determined based on the fact that the N pole of the first magnet approaches or is far away from the magnetometer and the S pole of the second magnet approaches or is far away from the magnetometer, and then the N pole of the first magnet and the S pole of the second magnet are required to be arranged to be opposite to the magnetometer in the later use. In the early test, the S pole of the first magnet and the N pole of the second magnet are required to be opposite to the magnetometer when the S pole of the first magnet approaches or departs from the magnetometer and the N pole of the second magnet approaches or departs from the magnetometer to determine the first preset magnetic field intensity range, the second preset magnetic field intensity range and the third preset magnetic field intensity range. The embodiment of the application is described by taking the example that the N pole of the first magnet and the N pole of the second magnet are opposite to the magnetometer.
It will be appreciated that the magnetic field strength at the periphery of the magnetometer is related to the magnetic field strength of the first and second magnets themselves, and therefore the magnets used in the early test should be consistent with the magnets used in the later test. And the magnetic field strengths of the first magnet and the second magnet may be the same or different.
In an actual use scenario, referring to fig. 10, fig. 10 is a schematic structural diagram of a connection between a female pogo-pin of a keyboard and a male pogo-pin of a tablet computer according to an embodiment of the present application. As shown in fig. 5 and 10, when a user needs to control the tablet pc 100 through the keyboard 200, that is, when the user needs to power up the external interface 70, the supporting portion 210 of the keyboard 200 is contacted with the rear surface of the tablet pc 100, so that the female end pogo-pin of the keyboard 200 is connected with the male end pogo-pin of the tablet pc 100, and the tablet pc 100 is supported by the supporting portion 210. When the female pin of the keyboard 200 is connected to the male pin of the tablet 100, the first magnet 204 is close to the magnetometer 60 along the Z-axis direction, and the N-pole of the first magnet 204 passes through the bottom surface 602 of the magnetometer 60, based on which the magnetometer 60 detects a magnetic field intensity of a large negative value (-Z-axis direction), for example, -B2. B2 is the magnetic field strength (also referred to as the first magnetic field strength) detected by the magnetometer 60 when the female pogo-pin of the keyboard 200 is connected to the male pogo-pin of the tablet computer 100. The processing module 90 collects the first magnetic field strength, compares the first magnetic field strength with a first preset magnetic field strength range, a second preset magnetic field strength range and a third preset magnetic field strength range stored in the processing module 90, and when the first magnetic field strength is within the first preset magnetic field strength range, the processing module 90 controls the switch circuit 80 to be turned on so as to power up the keyboard 200 through the power pin 72 of the external interface 70, and/or realizes interaction of data signals.
Referring to fig. 11, fig. 11 is a schematic structural diagram of the keyboard according to the embodiment of the present application when the main body of the keyboard is covered on the display screen and the female end pogo-pin of the keyboard is connected to the male end pogo-pin of the tablet computer. As shown in fig. 11, when the user uses the tablet pc 100 and needs the tablet pc 100 to be in a standby state, the keyboard main body 220 can be covered on the display screen 10 of the tablet pc 200 on the basis of keeping the connection between the female end pogo-pin of the keyboard and the male end pogo-pin of the tablet pc. When the keyboard main body 220 is covered on the display screen 10 of the tablet pc 200, the second magnet 205 approaches the magnetometer 60 along the Z-axis direction, and the N pole of the second magnet 205 passes through the top surface 601 of the magnetometer 60, so that the magnetometer 60 detects a magnetic field intensity of a positive value (+z-axis direction), for example +b1. Meanwhile, since the female pin of the keyboard 200 is connected to the male pin of the tablet pc 100, the first magnet 204 approaches the magnetometer 60 along the Z-axis direction, and the N-pole of the first magnet 204 passes through the bottom 602 of the magnetometer 60, the magnetometer 60 also detects a magnetic field intensity-B2 with a large negative value (-Z-axis direction). B1+ (-B2) is the magnetic field intensity (also referred to as the second magnetic field intensity) detected by the magnetometer 60 when the keyboard main body 220 is covered on the display screen 10 of the tablet pc 200 and the female end pogo-pin of the keyboard 200 is connected with the male end pogo-pin of the tablet pc 100. The processing module 90 collects the second magnetic field intensity, compares the second magnetic field intensity with the first preset magnetic field intensity range, the second preset magnetic field intensity range and the third preset magnetic field intensity range stored in the interior, when the second magnetic field intensity is within the second preset magnetic field intensity range, the processing module 90 controls the display screen 10 to be turned off so as to reduce power consumption, and the processing module 90 controls the switching circuit 80 to be turned on so as to power on the keyboard 200 through the power pin 72 of the external interface 70, and/or to realize interaction of data signals.
Referring to fig. 12, fig. 12 is a schematic structural diagram of a tablet computer according to an embodiment of the present application, where the tablet computer is not connected to a keyboard and the keyboard is not covered on the tablet computer. As shown in fig. 12, when the user does not use the keyboard 200, the keyboard can be removed from the tablet pc 100, and at this time, the male end pogo-pin of the tablet pc 100 is not connected to the female end pogo-pin of the keyboard 200, and the keyboard main body 220 of the keyboard 200 is not covered on the display screen 10 of the tablet pc 100, the magnetic field strength detected by the magnetometer 60 is changed from b1+ (-B2) to the original magnetic field strength. When the processing module 90 collects the magnetic field strength, the magnetic field strength is neither in the first preset magnetic field strength range nor in the second preset magnetic field strength range nor in the third preset magnetic field strength range, and therefore, the tablet pc 100 controls the display screen 10 to be turned on and controls the switch circuit 80 to be turned off.
Referring to fig. 13, fig. 13 is a schematic structural diagram of the display screen according to the embodiment of the present application. As shown in fig. 13, when the user simply puts the tablet pc 100 in a standby state through the keyboard 200, only the keyboard main body 220 may be covered on the display screen 10 of the tablet pc 200, and the female pogo-pin of the keyboard is not connected to the male pogo-pin of the tablet pc. When the keyboard main body 220 is covered on the display screen 10 of the tablet pc 200, the second magnet 205 approaches the magnetometer 60 along the Z-axis direction, and the N pole of the second magnet 205 passes through the top surface 601 of the magnetometer 60, based on which the magnetometer 60 detects a magnetic field intensity of a large positive value (+z-axis direction), for example, B1. B1 is the magnetic field strength (also referred to as the third magnetic field strength) detected by the magnetometer 60 when the keyboard main body 220 is covered on the display screen 10 of the tablet pc 200. The processing module 90 collects the third magnetic field intensity, compares the third magnetic field intensity with the first preset magnetic field intensity range, the second preset magnetic field intensity range and the third preset magnetic field intensity range stored in the processing module 90, and controls the display screen 10 to be turned off when the third magnetic field intensity is within the third preset magnetic field intensity range so as to reduce power consumption.
Therefore, the dual functions of the pogo pin disconnection detection and the detection of whether the keyboard main body part is covered on the display screen are realized through the single magnetometer, and the working state of the electronic equipment is controlled according to the detection result. Because single magnetometer compares in a plurality of hall devices, with low costs, and occupy electronic equipment inner space less, consequently, can realize reducing electronic equipment's cost to and reduce the effect that occupies electronic equipment inner space.
From the foregoing, it can be seen that magnetometer 60 can detect the magnetic field intensity in three dimensions (X-axis direction, Y-axis direction, and Z-axis direction) based on the magnetic field around it. The above examples are described by taking the comparison of the magnetic field intensity in one dimension as an example, but the present application is not limited thereto. In other alternative embodiments, to further improve the accuracy of the detection, the processing module 90 may further collect at least two of the X-axis direction (also referred to as a first direction) magnetic field strength, the Y-axis direction (also referred to as a second direction) magnetic field strength, and the Z-axis direction (also referred to as a third direction) magnetic field strength, and control the working state of the electronic device according to the correspondence between the pre-stored first preset magnetic field strength range, the pre-stored second preset magnetic field strength range, the pre-stored third preset magnetic field strength range, and the working state of the electronic device.
It is understood that when the magnetic field strength collected by the processing module 90 is at least two directions, the first preset magnetic field strength range, the second preset magnetic field strength range and the third preset magnetic field strength range also include the magnetic field strength ranges of at least two directions. In a possible implementation manner, the processing module 90 is specifically configured to collect the magnetic field strength in the first direction, the magnetic field strength in the second direction, and the magnetic field strength in the third direction, that is, collect the magnetic field strengths in the three directions, and control the working state of the electronic device according to the corresponding relationship between the magnetic field strength in the first direction, the magnetic field strength in the second direction, the magnetic field strength in the third direction, the pre-stored first preset magnetic field strength range, the pre-stored second preset magnetic field strength range, the pre-stored third preset magnetic field strength range, and the working state of the electronic device.
That is, the processing module 90 collects the magnetic field intensities of the magnetometer 60 in three directions, and correspondingly, the first preset magnetic field intensity range, the second preset magnetic field intensity range and the third preset magnetic field intensity range stored in the magnetometer also include the magnetic field intensity ranges of the three directions, that is, the first preset magnetic field intensity range of the first direction, the first preset magnetic field intensity range of the second direction, the first preset magnetic field intensity range of the third direction, the second preset magnetic field intensity range of the first direction, the second preset magnetic field intensity range of the second direction, the second preset magnetic field intensity range of the third direction, the third preset magnetic field intensity range of the first direction, the third preset magnetic field intensity range of the second direction and the third preset magnetic field intensity range of the third direction, so that the detection accuracy can be further improved.
With respect to the specific location of magnetometer 60 on PCB 40, embodiments of the present application do not limit the specific location of magnetometer 60.
In one possible implementation, with continued reference to fig. 11, when the female end pogo-pin of the keyboard 200 is connected to the male end pogo-pin of the tablet computer 100, the projection of the first magnet 204 on the plane of the PCB 40 overlaps with the projection of the magnetometer 60 on the plane of the PCB 40; when the keyboard main body 220 is covered on the display screen 10, the projection of the second magnet 205 on the plane of the PCB 40 overlaps with the projection of the magnetometer 60 on the plane of the PCB 40, so that the magnetometer 60 can detect a larger magnetic field strength in a certain direction (such as the Z-axis direction), and the detection accuracy is improved.
On this basis, when the processing module 90 collects only the magnetic field intensity in one-dimensional direction, and compares the magnetic field intensity in the one-dimensional direction with the preset magnetic field intensity range, the one-dimensional direction may be the Z-axis direction.
In yet another possible implementation, with continued reference to fig. 5, the tablet computer 100 includes opposite first and second edges 101 and 102, and the keyboard 200 further includes a connection portion 230, and the keyboard body portion 220 is connected to the support portion 210 by the connection portion 230. Referring to fig. 8, when the keyboard 200 is in the covering state, the first edge 101 contacts the connection portion 230, and the second edge 102 is located on a side of the first edge 101 facing away from the connection portion 230.
