Description

TECHNICAL FIELD

[0001] The present application relates to the field of electronic devices, in particular to a pen-up detection device and a detection method thereof, and an electronic device. BACKGROUND

[0002] An intelligent interactive panel is usually equipped with a corresponding touch pen. In view of the control requirement of the intelligent interactive panel, pen-up detection of the touch pen is required in some scenarios, that is, whether the touch pen fixed at a certain position of the intelligent interactive panel is picked up is detected. There are two common pen-up detection schemes at present.

[0003] The first one is an infrared sensor detection scheme. Specifically, when the touch pen is adsorbed, the touch pen blocks the infrared rays to form reflection, and the infrared receiving end can receive the infrared signal, so the system can determine that this is a pen adsorption state. When the pen is picked up, the infrared rays cannot form reflection, and the infrared receiving end cannot receive the infrared signal, so the system can determine that this is a pen-up state. The defect of this method is that an opening needs to be made on the appearance of the intelligent interactive panel to allow the infrared rays to irradiate to the adsorption position of the touch pen, which destroys the integrity of the appearance of the whole machine, and when other opaque objects block the adsorption position of the touch pen, it will cause misjudgment.

[0004] The second one is a Hall sensor detection scheme. Specifically, when the pen is adsorbed or picked up, the Hall sensor detects the change of the magnetic field, and then converts it into the change of the current in the circuit, so that the system determines that the touch pen is in the adsorption state or the pen-up state. The problem of this method is that when the intelligent interactive panel is used with a blackboard that can be pushed and pulled, the Hall sensor may be triggered by mistake due to the pushing and pulling of the blackboard, and finally misjudgment occurs.

[0005] Therefore, the detection accuracy of the current pen-up detection scheme cannot meet the requirement.

[0006] Currently, there is no effective solution to the problem that the detection accuracy of the pen-up detection scheme in the related art cannot meet the requirement. SUMMARY

[0032] Embodiment 1

[0033] According to an embodiment of the present application, an embodiment of a pen-up detection device is provided, Figure 1 is a schematic diagram of a pen-up detection device according to an embodiment of the present application, which is arranged close to a preset frame of an electronic device, as shown in the figure, the pen-up detection device 10 comprises: Figure 1 a fixed support (not shown in the figure), a base 11;

[0034] a pressure sensor 12 arranged on the base 11 of the fixed support, the pressure sensor 12 is used for detecting pressure data;

[0035] a elastic element 13 arranged on the base 11 of the fixed support;

[0036] a metal element 14 fixed on the elastic element 13 and covering the pressure sensor 12, wherein when the elastic element 13 is in a natural elongation state, there is a gap between the metal element 14 and the sensing surface of the pressure sensor 12;

[0037]

[0038] ​A processor 15 is in communication with the pressure sensor 12, and the processor 15 is configured to detect a change in the state of the stylus according to pressure data acquired from the pressure sensor 12.

[0039] The state of the stylus includes an adsorbed state and a lifted state. The adsorbed state indicates that the stylus is adsorbed outside the preset frame by the magnet. The lifted state indicates that the stylus is separated from the preset frame.

[0040] Specifically, the base 11 can be a part of a fixed support for carrying other elements. The preset frame can be any outer frame of the electronic device, that is, the stylus detection device 10 can be arranged inside any frame according to actual needs, for example, the stylus detection device 10 can be arranged inside the lower frame of the electronic device. The elastic element 13 can be a return spring, and the metal element 14 can be an iron block. The processor 15 can be an MCU capable of communicating with the main control of the electronic device.

[0041] Figure 2 is a schematic view of a stylus according to an embodiment of the present application, in combination with Figure 2 As shown, the stylus 21 is provided with a magnet 22. When the stylus 21 approaches the preset frame of the electronic device, the magnet 22 is adsorbed outside the preset frame of the electronic device by attracting the metal element 14 in the stylus detection device 10.

[0042] Figure 3 is a schematic view of a stylus detection device arranged inside a frame of an electronic device according to an embodiment of the present application, in combination with Figure 3 As shown, the stylus detection device 10 is arranged inside a frame 30 of the electronic device. The base 11 of the stylus detection device 10 is close to the inner surface of the frame 30.

[0043] In combination with Figure 1 , Figure 2 and Figure 3 As shown in an optional embodiment, the base 11 of the stylus detection device 10 is arranged close to the inside of the lower frame of the electronic device. When the stylus 21 approaches the lower frame of the electronic device, the stylus 21 is adsorbed outside the lower frame of the electronic device due to the attraction of the magnet 22 to the metal element 14. At this time, the magnet 22 arranged on the stylus 21 adsorbs the metal element 14, so that the metal element 14 compresses the elastic element 13 and presses the sensing surface of the pressure sensor 12. The pressure sensor 12 detects an increase in pressure. Based on this principle, the processor 15 can determine that the state of the stylus changes from the lifted state to the adsorbed state when the pressure data detected by the pressure sensor 12 increases.

[0044] When the user picks up the stylus 21, the metal element 14 is no longer attracted by the magnet 22 and leaves the pressure sensor 12 under the action of the elastic element 13, so that the pressure sensor 12 no longer generates pressure, and the pressure data detected by the pressure sensor 12 becomes smaller as the stylus 21 is picked up. Based on this principle, the processor 15 can determine that the stylus state changes from the adsorption state to the picking-up state when the pressure data detected by the pressure sensor 12 becomes smaller, thereby realizing stylus picking-up detection.

[0045] It can be seen that the stylus picking-up detection device provided in the above embodiments of the present application is arranged close to the preset frame of the electronic device, and specifically includes: a fixed support; a pressure sensor arranged on the base of the fixed support, the pressure sensor being configured to detect pressure data; an elastic element arranged on the base of the fixed support; a metal element fixed on the elastic element and covering the pressure sensor, wherein the metal element has a gap with the sensing surface of the pressure sensor when the elastic element is in a natural elongation state; and a processor in communication with the pressure sensor, the processor being configured to detect changes in the stylus state according to the pressure data obtained from the pressure sensor; wherein the stylus state includes an adsorption state and a picking-up state. In the above scheme, the stylus picking-up detection is realized by the pressure of the metal element in the stylus picking-up detection device on the pressure sensor in different states of the stylus. Through such a detection method, the interference of non-transparent substances on the infrared signal when the stylus picking-up detection is performed by infrared rays can be avoided, and the false triggering of the Hall sensor caused by the movement of other objects around the electronic device when the stylus picking-up detection is performed by the Hall sensor can also be avoided. Therefore, the detection accuracy is high, the technical problem that the detection accuracy of the stylus picking-up detection scheme in the related art cannot meet the requirements is solved, and the overall structure is simple and convenient to disassemble and maintain.

[0050] The two positioning pins 42 respectively pass through the first accommodating hole 41 of the reset spring 13 and the metal element 14, and the metal element 14 is fixed on the upper end of the reset spring 13 through a fixing pin 43.

[0051] In the above scheme, the positioning pin 42 is arranged on the base 11, and sequentially passes through the reset spring 13, the first accommodating hole 41 of the metal element 14 from bottom to top, and exposes the second accommodating hole 44 on the positioning pin 42 above the metal element 14. The fixing pin 43 is inserted into the second accommodating hole 44, so that the metal element 14 is fixed on the reset spring 13.

The fixing member 45 can have a threaded hole, and the pen lifting detection device 10 can be fixed inside the preset frame of the electronic device by screwing.

[0055] As an optional embodiment, still in combination with Figure 1 and Figure 4 It is shown that the pen lifting detection device 10 further comprises:

[0056] The signal conversion device 46 communicates with the pressure sensor 12 and the processor 15 respectively, and is used for sending the pressure data detected by the pressure sensor 12 to the processor 15 after analog-digital conversion.

[0057] In the above scheme, the signal conversion device 46 receives the pressure data uploaded by the pressure sensor 12, performs analog-digital conversion on the pressure data, and sends the conversion result to the processor 15. The processor 15 judges the state of the touch pen according to the pressure data, that is, performs pen lifting detection.

[0058] Figure 5 It is a front view of a pen lifting detection device according to an embodiment of the present application, in combination with Figure 5As shown, the pen-up detection device has a fixed support 40, which is connected to the inner side of the lower frame of the electronic device through the fixing member 45 by screwing; the signal conversion device 46 is screwed on the upper surface of the fixed support 40; the pressure sensor 12 is pasted on the base 11 of the fixed support 40 through the back glue, and the signal line of the pressure sensor 12 is connected with the signal conversion device 46 through the opening (not shown in the figure) on the back side of the fixed support; the reset spring 13 is sleeved on the positioning pin 44 of the fixed support 40; the metal element 14 is sleeved on the positioning pin 44 and presses the reset spring 13, and the position is limited through the fixed plug 43.

[0059] As an optional embodiment, the processor is further configured to determine that the state of the stylus is changed from the pen-up state to the adsorption state when the increase value of the pressure data is greater than a first preset value, and determine that the state of the stylus is changed from the adsorption state to the pen-up state when the decrease value of the pressure data is greater than a second preset value.

[0064] In an alternative embodiment, the electronic device is configured to wake up when the stylus is lifted. When the user lifts the stylus from outside the frame of the electronic device, the processor determines that the stylus is lifted by detecting that the pressure data becomes smaller, and sends the state to the SOC, which controls the electronic device to wake up.
