Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus consistent with some aspects of the disclosure as detailed in the accompanying claims.

As shown in fig. 1 and 2, an embodiment of the present disclosure provides a detection module of a stylus, where the detection module of the stylus includes:

a fixedly arranged first magnet 11;

the second magnet is movably arranged between the first magnet 11 and the placement position of the touch control pen; wherein the magnetism of the second magnet 12 is opposite to that of the first magnet 11; under the condition that the placement position places the touch pen, the first attractive force is larger than the second attractive force, so that the second magnet is located at the first position; in the case where the stylus is not placed in the placement position, the second magnet 12 is located in a second position; the first attractive force is a magnetic attractive force between the second magnet 12 and the stylus; the second attractive force is a magnetic attractive force between the first magnet 11 and the second magnet 12;

a detection circuit 13. The detection circuit 13 is configured to detect whether the stylus pen is placed in the placement position according to the position of the second magnet.

The stylus may be any device capable of touching and/or writing on a touch screen. For example, the stylus housing is a shaft, which is convenient for a user to hold. Illustratively, the length of the stylus may be substantially greater than the length of the placement location, and/or the width of the stylus may be substantially greater than the width of the placement location, but when the stylus approaches the placement location, the stylus may attract the second magnet 12 due to the magnetic force, so that the second magnet 12 may attract the stylus at the placement location, thereby achieving storage of the stylus. However, since the interaction force between the second magnet 12 and the stylus is limited, the user can remove the stylus from the place by applying a certain force. Fig. 6 shows a stylus 20, and a third magnet 21 that attracts the second magnet is provided on the stylus 20.

Also for example, the length of the placement bit may be slightly greater than the length of the stylus and/or the width of the placement bit may be slightly greater than the width of the stylus so that the stylus may fit at the placement bit. For example, at least one position of the placement position is provided with a structure for fixing the stylus pen by means of a card and the like, and when the stylus pen is placed, the second magnet 12 moves in the direction of the placement position and is displaced to the first position due to the magnetic force.

In short, the structure of the placement bits is not particularly limited to any of the above.

Illustratively, both the first magnet 11 and the second magnet 12 may be permanent magnets. For example, the first magnet 11 and the second magnet 12 are both magnet pieces, and are provided in a sheet-like structure, so that the weight and the thickness can be reduced as much as possible.

The first magnet 11, which is fixedly provided, is a magnet that is not movable within the electronic device. While the movably arranged second magnet is movable but now allowed to move in the active space. Illustratively, a movable cavity, i.e., the aforementioned interaction space, is formed by the housing or the bracket, within which the second magnet 12 is movable.

In the embodiment of the disclosure, the first position and the second position may be two positions oppositely disposed in the active space. Illustratively, the spacing between the first location and the placement site is less than the spacing between the second location and the placement site. State 1 shown in fig. 3 is a schematic view of the second magnet 12 in the first position. State 2 shown in fig. 4 is a schematic view of the second magnet 12 in the second position. As shown in fig. 3, if the stylus pen is placed on the prevention position, a magnetic force F1 is generated between the stylus pen and the second magnet, and a magnetic force position F2 between the two magnets is larger than F2, so that the second magnet approaches the prevention position under the action of the magnetic force difference.

The detection circuit 13 may be any analog circuit or a circuit that converts an analog signal into a digital signal. For example, the detection circuit 13 may be any circuit capable of detecting the position of the second magnet, or the detection circuit 13 may also be a circuit that detects the magnetic force at the placement position, and the position of the second magnet is determined by the process of detecting the placement position.

Illustratively, both the first magnet 11 and the second magnet may be disposed adjacent to the stylus rest position. For example, the first magnet 11 and the second magnet 12 are disposed at the place such that the first magnet 11, the second magnet 12, and the third magnet or iron piece on the stylus interact with each other by magnetic force.

For example, if there is no stylus on the placement position, the magnetism of the first magnet 11 and the magnetism of the second magnet 12 are opposite, so that the second magnet 12 is as close to the first magnet 11 as possible. And when the touch pen is placed on the placement position. The stylus pen has a structure in which a third magnet, iron piece, or the like can attract the second magnet 12 by magnetic force. And at this time, the magnetic force between the second magnet and the stylus pen is greater than the magnetic force between the second magnet 12 and the first magnet 11, and thus, the second magnet 12 is moved toward the placement position of the stylus pen, thereby increasing the distance between the first magnet 11 and the second magnet 12, and thus, the second magnet 12 is moved from the second position to the first position.

If the stylus carries the third magnet, the magnetism of the third magnet is opposite to that of the second magnet 12 and the same as that of the first magnet 11.

In some embodiments, the detection circuit 13 has a first connection and a second connection;

a first connection end for contacting the second magnet 12 in the first position;

and a second connection end for contacting a second magnet 12 in said second position.

Because the detection circuit 13 has the first connection end and the second connection end, and the first connection end and the second connection end can be connected with the second magnet of different positions respectively, and the second magnet can only be located in the first position or the second position at a moment, the second magnet is connected with the first connection end electricity and the second magnet is connected with the second connection end electricity two states, and whether the place has the stylus pen or not has been realized. The magnet and the conventional detection circuit 13 have the characteristics of simple structure and low cost compared with a hall element formed of a hall semiconductor.

In some embodiments, as shown in fig. 4, the detection circuit 13 includes:

a first sub-circuit 131 connected to the first connection terminal and a ground point; the second magnet 12 is located at the first position, and the first sub-circuit 131 is turned on;

a second sub-circuit 132 connected to the second connection terminal and a ground point; the second magnet 12 is in the second position and the second sub-circuit 132 is conductive.

Thus, the second magnet 12 is at a different position, and different sub-circuits of the detection circuit 13 are turned on. If the second magnet 12 is at the first position, the second magnet 12 will turn on the first sub-circuit 131 and the second sub-circuit 132 will turn off. If the second magnet 12 is at the second position, the second magnet 12 turns on the second sub-circuit 132 and the first sub-circuit 131 turns off. If the first sub-circuit 131 and the second sub-circuit 132 are simultaneously in the off state, it is considered that the detection circuit 13 is abnormal, and the abnormality can be eliminated by restarting the detection circuit 13 or by turning on the third sub-circuit 133.

Illustratively, the third sub-circuit 133 may include a winding that may be wound on the first magnet 11. The windings may increase the magnetic properties of the first magnet 11 such that energizing the windings increases the magnetic force of the first magnet 11 such that the stuck second magnet 12 returns to the second position under the influence of the larger magnetic force, thereby contacting the anomaly that the first sub-circuit 131 and the second sub-circuit 132 are simultaneously opened.

In some embodiments, the first sub-circuit 131 and the second sub-circuit 132 may be two sub-circuits disposed in parallel. At least one electronic component of the two sub-circuits is different. The impedance values of the first sub-circuit 131 and the second sub-circuit 132 are different, so that the first sub-circuit 131 and the second sub-circuit 132 generate different current values, different current directions, and/or output voltages under the action of the same power source, and thus, the current and/or the voltage output by the detection circuit 13 represent two states of whether the placing bit has a stylus pen, thereby completing the detection of whether the placing bit has a stylus pen.

For example, the first sub-circuit 131 has a first resistor R1, the second sub-circuit 132 has a second resistor R2, and the resistances of the resistors R1 and R2 are different, so that the voltage drops on the resistors R1 and R2 are different under the same current, and the voltage drop can be used as a basis for determining whether there is a stylus on the placement bit.

In an exemplary embodiment, the impedance of the first sub-circuit 131 is the same as that of the second sub-circuit 132, and the first sub-circuit 131 and the second sub-circuit 132 are connected to voltage sources with different voltages, so that the voltages output when the first sub-circuit 131 and the second sub-circuit 132 are turned on are different, and the output voltage can be used as a basis for determining whether there is a stylus on the placement bit.

Illustratively, the second magnet 12 may be an electrically conductive magnet, including but not limited to: neodymium-iron-boron strong magnets, samarium-cobalt magnets, alnico magnets, and/or iron-chromium-cobalt magnets. In this way, the second magnet 12 itself is in contact with the different sub-circuits at different positions, so that the corresponding sub-circuit can be conducted, and the second magnet 12 itself acts as a switch.

Also by way of example, the second magnet 12 may be any device such as a magnet having magnetic properties. The second magnet 12 has a conductive sheet on its outer surface, and the conductive sheet contacts the first connection end or the second connection end when the second magnet 12 is positioned at a different position. In this way, the second magnet 12 can act as a carrier for the conductive sheet, and the switching action is achieved integrally with the conductive sheet.

Also illustratively, the first connection of the first sub-circuit 131 and the second connection of the second sub-circuit 132 are both provided with a resilient switch, which is closed by the second magnet 12 if the second magnet 12 is in the first position, and which is otherwise open. If the second magnet 12 is in the second position, the resilient switch at the second connection end is closed under the influence of the second magnet 12, otherwise open. In such an embodiment, the second magnet acts as a trigger for the on or off of the first sub-circuit 131 and the second sub-circuit 132.

In some embodiments, the first sub-circuit 131 has a power supply thereon.

For example, the first sub-circuit 131 has a power supply, and the power supply provides a power supply voltage, so that when the first sub-circuit 131 is turned on, a larger voltage drop or a larger current is provided in the first sub-circuit 131, so that the detection of the placement position of the stylus pen can be realized.

Further, the first sub-circuit 131 has a power supply, while the second sub-circuit 132 has no power supply. Illustratively, the power supply of the first sub-circuit 131 may provide an operating voltage VDD, which may be a dc voltage. The operating voltage may be, for example, 1.5 or 1.2V or 3.2V, etc.

Referring to fig. 5, the first sub-circuit 131 may include a power supply and R1 connected in series. The second sub-circuit 132 may include: r2. The power supply provides an operating voltage VDD. After the power supply and R1 are connected in series, the power supply is connected between the grounding point and the first connecting end. The first sub-circuit is turned on when the second magnet 12 is in state 1, and is otherwise turned off. The second sub-circuit is turned on when the second magnet 12 is in state 2, and is otherwise turned off.

In some embodiments, the detection circuit 13 further comprises:

the third sub-circuit 133 includes:

a first input terminal electrically connected to the second magnet 12, the first input terminal being for inputting a detection signal;

a second input terminal for inputting a reference signal;

The third sub-circuit 133 may be a three terminal device. Two of the three-terminal devices are input ends, namely a first input end and a second input end, and the other is an output end. And the output end is used for outputting a detection result, and the detection result can be a detection level for indicating whether the placement position has a touch pen or not.

If the detection signal is a detection voltage, the reference signal may be a reference voltage, which may be provided by a reference voltage source.

If the sense signal is a sense current, the reference signal may be a reference current, which may also be provided by a current source.

If there is a stylus on the placement position, the second magnet 12 is located at a different position, the detection signal input by the third sub-circuit 133 is different, and the reference signal remains substantially constant. In this case, the detection result output from the output terminal is output based on the magnitude comparison of the detection signal and the reference signal, and the detection result may be mapped into a boolean logic variable.

In some embodiments, the third sub-circuit 133 includes: a comparator or an operational amplifier.

In the embodiment of the disclosure, the comparator or the operational amplifier is used for comparing the detection signal and the reference signal, and the device has the characteristics of simple structure and low hardware cost.

As shown in fig. 5, the third sub-circuit may include a power supply VS1, the power supply VS1 providing an operating voltage required by the third sub-circuit. If the second magnet 12 is in state 1, the third sub-circuit is turned on with the first sub-circuit; if the second magnet 12 is in state 2, the third sub-circuit and the second sub-circuit are conductive.

The third sub-single-pass further comprises an operational amplifier (Operational Amplifier, PAMP). The OPAMF comprises an input 3; and an output 6. The input terminal 2 is for connection to a first sub-circuit or a second sub-circuit. A reference power supply Vref is connected between the input terminal 2 and the ground point. The OPAMF further comprises a terminal 4 and a terminal 7, the terminal 4 being connected to the power source VS1, the terminal 4 being grounded.

In some embodiments, in the case that the placement position places a stylus pen, the second magnet 12 and the first magnet 11 have a first interval therebetween; with no stylus at the placement position, a second distance is provided between the second magnet 12 and the first magnet 11; the first pitch is greater than the second pitch.

Illustratively, the second magnet 12 is positioned between the first magnet 11 and the rest position such that the second magnet 12 is also constrained to movement between the first magnet 11 and the rest position. Illustratively, the surface of the first magnet 11 is also provided with an isolating layer; in this way, even when the second magnet 12 is located at the second position, the first magnet 11 and the second magnet 12 are not in direct contact, and when the stylus pen is placed at the subsequent placement position, the second magnet 12 is more easily separated from the first magnet 11 and moves to the first position, so that the detection circuit 13 detects that the stylus pen is placed at the placement position.

As shown in fig. 7, an embodiment of the present disclosure provides an electronic device 30 that may include:

a housing 31 having a stylus pen disposed on one outer surface thereof;

the detection module of the stylus provided in any one of the foregoing embodiments is located in the housing, where the first magnet 11 and the second magnet 12 of the detection module of the stylus are located at the bottom of the placement position.

The housing may be a casing of an electronic device.

The electronic device may be an electronic device that includes a touch screen 32. For example, the touch screen 32 is installed in the accommodating cavity formed by the housing 31, and the window area and the touch area of the touch screen are exposed through the opening on the housing.

The electronic device may be a tablet computer, a notebook computer, or a tablet and notebook two-in-one device, or an in-vehicle device, for example.

The housing may surround a casing of the touch screen, forming an outer frame of the touch screen. The placement bits of the stylus may be located on the side of the outer frame of the touch or on the bottom surface of the electronic device.

As shown in fig. 8, the placement position 41 of the stylus is disposed on the outer surface of the housing 31, and the detection module of the stylus is disposed in the housing, so that the housing can also protect the detection module of the stylus.

In some embodiments, the electronic device further comprises:

the processing module is positioned in the shell;

and a general purpose input/Output (GPIO) pin of the processing module is electrically connected with the Output end of the detection circuit 13 of the detection module of the touch control pen.

The processing module may be a central processing unit (Central Processing Unit, CPU), a microprocessor (Microprocessor Unit, MCU) or an embedded controller (Embedded Controller, EC).

The detection module is directly connected with the GPIO pin of the processing module, so that the processing module can directly receive the detection result and rapidly judge whether the placement position has a touch control pen or not.

In some embodiments, as shown in fig. 8, the housing 31 has an aperture; the openings are filled with a cover layer 42; the cover layer is recessed toward the center of the shell to form the placement position 41;

the first magnet 11 is fixed below the cover layer, and the second magnet 12 is located between the cover layer and the first magnet 11.

The cover 42 may be a plastic cover or a plastic ferrule covering the opening. And the top of the covering layer is recessed towards the center of the shell to form a placement position. The first magnet 11 is fixed in the housing below the cover layer. The second magnet 12 is located between the cover layer and the first magnet 11 such that the second magnet 12 moves towards the rest when the stylus is placed on the rest.

Illustratively, the placement locations are located on a side surface of the housing.

The placement position is a side surface of the shell, does not occupy the position of the front surface, and does not influence the duty ratio of the touch screen; the electronic equipment can not be influenced to be horizontally placed on the desktop without occupying the position of the back surface of the shell.

The Hall magnetic field detection structure and the device cost are high, and a plurality of items carrying the touch pen cancel the touch pen in-situ detection, so that the user experience is reduced to a certain extent;

the original detection technical scheme is cancelled, two permanent magnets are added at the position where the touch pen is placed, when the touch pen is not placed, the second magnet 12 is attracted by the first magnet 11, and the second magnet 12 is in a restrained state and cannot move randomly, and the method can be specifically described with reference to fig. 4.

When the stylus is not placed, the state 2 is the state, the second magnet 12 is fixed by the first magnet 11, the first magnet 11 is embedded in the product structure, the state 1 is changed after the stylus is placed, and as F1 > F2, the second magnet 12 is attracted to the top and then limited.

The second magnet 12 may act as a single pole double throw switch. The detection circuit is shown in fig. 4. The identification logic of the detection circuit is as follows: the state 2 comparator outputs a low level, the state 1 is switched after the stylus is placed, the comparator outputs a high level, and the processor detects that the stylus is placed.

According to the embodiment of the disclosure, the Hall element is replaced by 2 small magnets, the electromagnetic coupling scheme is converted into a pure physical detection scheme, meanwhile, the reliability is guaranteed, and compared with the original scheme, the cost is greatly reduced.
