Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.
Fig. 1 is a schematic structural diagram of an electronic system 100 according to an embodiment of the present disclosure. The electronic system 100 provided by the embodiment of the present application includes an electronic pen 10 and an electronic device 20.
The electronic device 20 may be a device that can be used with the electronic pen 10, such as a mobile phone, a tablet computer, a desktop computer, a laptop computer, an e-reader, a handheld computer, an electronic display screen, a notebook computer, a netbook, a media player, etc. The electronic device 20 includes a touch screen 201. The embodiment of the present application takes a foldable mobile phone as an example for explanation. The foldable mobile phone has the characteristics of large screen display when unfolded and convenient carrying after being folded. Because of its requirement for folding the touch screen 201, the touch screen 201 of the foldable mobile phone is usually made of a film material with a low storage modulus. For example: the cover plate layer is made of transparent Polyimide (CPI) Film or Ultra-thin glass (UTG) to realize the folding performance. Therefore, the cover plate layer of the touch panel 201 of the foldable mobile phone has low rigidity, and when the electronic pen 10 is disposed and used, the resistance between the electronic pen 10 and the touch panel 201 is large, so that although the hand feeling of the electronic pen 10 during writing is increased, the pen point of the electronic pen 10 is easily worn, and if the worn electronic pen 10 has a metal tip exposed, scratches are easily generated on the touch panel 201. The touch screen 201 of the electronic device 20 may be a capacitive touch screen, an electromagnetic touch screen, or the like.
Referring to fig. 1 and 2, the electronic pen 10 may be a resistive sensing electronic pen, a capacitive sensing electronic pen, an electromagnetic sensing electronic pen, or the like. When the electronic pen 10 approaches or contacts the touch screen 201 of the electronic device 20, the touch screen 201 transmits an electronic signal and receives an electronic signal fed back by the electronic pen 10 to recognize the touch of the electronic pen 10. The embodiment of the present application takes an active capacitive stylus as an example for description. The active capacitive stylus can receive an electronic signal transmitted by the capacitive touch screen 201, so as to realize pairing of the active stylus and the touch screen 201, function setting of the active stylus, and the like. In addition, the active stylus can also transmit an electronic signal to the touch screen 201, so as to transmit position information, pressure information and the like of the active stylus to the touch screen 201, thereby realizing note recording, drawing creation, document writing, drawing and the like of the active stylus on the touch screen 201. Generally, the tip 101 of the active stylus is finer and more precise. If the tip 101 of the active stylus directly contacts the touch screen 201, scratches are easily generated on the touch screen 201. Of course, in other embodiments, the electronic pen 10 may also be a passive stylus. The passive stylus passively influences the capacitance in the touch screen 201 through the relatively thick pen point 101, so as to realize touch control. The nib 101 of the passive stylus is a metal nib 101, which is hard and easily scratches the capacitive touch screen 201.
Specifically, as shown in fig. 3, the electronic pen 10 includes a pen tip 101, a pen head 102, a first receiving element 103, and a signal detecting element 104.
Referring to fig. 3 and 4, the pen tip 101 includes a first end 110 and a second end 112 connected to each other, and the first end 110 of the pen tip 101 is in a shape of a semi-circular arc. The second end 112 of the nib 101 is a round rod. Of course, in other embodiments, the first end 110 of the pen tip 101 may also be a disk, a sphere, etc. The second end 112 of the nib 101 may also be flat, elongated, etc. The first end 110 of the pen tip 101 extends into the pen tip 102 for receiving the scanning electronic signal emitted by the touch screen 201 (refer to fig. 2), and transmitting the received scanning electronic signal to the second end 112 of the pen tip 101. The second end 112 of the tip 101 is adapted to be connected to any one or more of an electronic signal receiver, an electronic signal transmitter, an electronic signal amplifier, an electronic signal processor or controller, and the like. The semi-arc-shaped first end 110 and the round rod-shaped second end 112 are convenient to insert into the pen tip 102, and are beneficial to subsequent replacement of the pen tip 102.
Optionally, the pen tip 101 may be made of a metal conductive material, which has a relatively high hardness, so that the pen tip 101 is easy to control in use, and can better receive the scanning electronic signal emitted by the touch screen 201. In addition, the pen tip 101 may be made of other conductive materials, such as: conductive hard plastics, conductive alloys, and the like. Of course, in other embodiments, the material of the pen tip 101 may also be a flexible conductive material, such as: conductive silicone, conductive resin, conductive rubber, and the like.
Referring to fig. 3 to 5, the outer surface of the pen tip 102 includes a first end surface 120, a second end surface 122 and a peripheral side surface 123 connected between the first end surface 120 and the second end surface 122. The first end surface 120 may be a convex arc. The second end surface 122 may be a flat surface or an arcuate surface. The first end surface 120 is used for directly contacting the touch screen 201 of the electronic device 20. The pen tip 102 is wrapped around one end of the pen tip 101. Specifically, the pen tip 101 is partially inserted into the pen tip 102, the first end 110 of the pen tip 101 is located in the pen tip 102, and the second end 112 of the pen tip 101 penetrates the second end surface 122 of the pen tip 102 and at least partially protrudes out of the pen tip 102. Optionally, the pen tip 102 may be a rubber sleeve, a silicone sleeve, a resin protective sleeve, or the like. The tip 102 is removable from the nib 101 and may be replaced when worn. The pen point 102 directly contacts the touch screen 201 (refer to fig. 1), and the friction between the pen point 102 and the touch screen 201 is large in the using process, so that the writing hand feeling can be improved. In addition, the pen point 102 can be a flexible pen point which is soft, and the first end surface 120 of the pen point 102 can be an arc surface, so that the contact area between the pen point and the touch screen 201 can be increased, and the electronic device 20 is not easily scratched in actual use.
The first receiving element 103 is disposed in the pen tip 102 and located between the first end 110 of the pen tip 101 and the first end surface 120 of the pen tip 102. Specifically, the first end 110 of the pen tip 101, the first receiving element 103, and the first end surface 120 of the pen tip 102 are arranged in this order. The first receiving member 103 is spaced from the first end 110 of the nib 101 to prevent the nib 101 from being exposed when the first receiving member 103 is partially worn. In other words, a certain gap is reserved between the first receiving element 103 and the first end 110 of the pen tip 101 to ensure that the pen tip 101 is not exposed after the first receiving element 103 is partially or completely worn, and at this time, the electronic pen 10 can be used continuously for a short time to reserve time for the user to replace. The first receiving element 103 is spaced from the first end 120 of the tip 102. When the electronic pen 10 is used, the first end surface 120 of the pen tip 102 directly contacts the touch screen 201, after a long time of use, the pen tip 102 gradually wears, and the first receiving element 103 gradually approaches the touch screen 201 until the first receiving element 103 is worn. It will be understood that the distance between the first receiving element 103 and the first end face 120 of the nib 102 corresponds to the useful life of the nib 102. In the case that writing by the pen tip 101 is satisfied, and the pen tip 101 can better receive the scanning electronic signal emitted by the touch screen 201, the distance between the first receiving element 103 and the first end face 120 of the pen tip 102 can be adaptively increased. The hardness of the first receiving element 103 is less than that of the pen tip 101, so as to prevent the touch screen 201 from being scratched by the first receiving element 103.
The first receiving element 103 is used for receiving an electronic signal between the pen tip 101 and the touch screen 201. The first receiving element 103 comprises a conductor that receives an electronic signal to generate an induced signal.
Referring to fig. 2 and fig. 3, in an embodiment, the first receiving element 103 is used for receiving an electronic signal emitted by the touch screen 201. The electronic signal emitted by the touch screen 201 is a scanning electronic signal emitted by the touch screen 201. In other words, in the process of transmitting the scanning electronic signal emitted by the touch screen 201 to the pen tip 101, a part of the scanning electronic signal passes through the first receiving element 103 and is received by the first receiving element 103, and at this time, the first receiving element 103 generates a sensing signal. The induced signal may be an induced current, an induced charge, an electromagnetic signal, or the like. In this embodiment, the first receiving element 103 receives an electronic signal transmitted from the touch screen 201 to the electronic pen 10, and generates a sensing signal.
In another embodiment, the first receiving element 103 is used to receive electronic signals emitted by the pen tip 101. The electronic signal emitted by the pen tip 101 is a driving electronic signal, and the driving electronic signal is emitted to the touch screen 201 through the pen tip 101 to interfere with or enhance the original scanning electronic signal on the touch screen 201, so that the touch screen 201 can determine the touch position of the pen tip 101 of the electronic pen 10 on the touch screen 201. In the process of transmitting the driving electronic signal emitted by the pen tip 101 to the touch screen 201, a part of the driving electronic signal passes through the first receiving element 103 and is received by the first receiving element 103, and at this time, a sensing signal is generated on the first receiving element 103. In this embodiment, the first receiving element 103 receives an electronic signal transmitted from the electronic pen 10 to the touch screen 201 through the pen tip 101, and generates a sensing signal. In one embodiment, the amplitude, frequency and phase of the driving electronic signal emitted by the stylus 101 is related to the scanning electronic signal it receives and sent to it by the touch screen 201.
In another embodiment, the first receiving element 103 receives both the scanning electronic signal emitted from the touch screen 201 and the driving electronic signal emitted from the electronic pen 10. When the electronic pen 10 approaches or touches the touch screen 201, a part of the scanning electronic signal emitted by the touch screen 201 passes through the first receiving element 103 and is received by the first receiving element 103 in the process of being transmitted to the pen tip 101, and then a first sensing signal is generated on the first receiving element 103. When the electronic pen 10 receives the scanning electronic signal and generates a driving electronic signal according to the scanning electronic signal, and the pen tip 101 transmits the generated driving electronic signal to the touch screen 201, a part of the driving electronic signal passes through the first receiving element 103 and is received by the first receiving element 103, and then a second sensing signal is generated on the first receiving element 103. Of course, in other embodiments, the electronic signal can also be transmitted between the pen tip 101 and the touch screen 201 through an external transmitter, and at this time, the first receiving element 103 receives the electronic signal transmitted by the external electronic signal transmitter. Alternatively, the first receiving element 103 may include a metal conductive wire, a conductive coil, a metal sheet, an antenna, or the like.
As shown in fig. 3, the signal detection element 104 is electrically connected to the first receiving element 103. The signal detection element 104 is used for detecting the magnitude of the electronic signal on the first receiving element 103. It will be appreciated that the signal detection element 104 is adapted to detect the magnitude of the induced signal on the first receiving element 103 in order to determine the wear of the first receiving element 103.
The magnitude of the electronic signal received by the first receiving element 103 decreases as the amount of wear of the first receiving element 103 increases. Specifically, when the first receiving element 103 is not worn or is worn less, the first receiving element 103 receives more electronic signals to generate a stronger sensing signal, and at this time, the signal detecting element 104 detects that the sensing signal generated on the first receiving element 103 is larger, so as to determine that the first receiving element 103 is not worn or is worn less. When the first receiving element 103 is worn seriously or worn completely, the electronic signal received by the first receiving element 103 is weak or cannot receive the electronic signal, and at this time, the signal detecting element 104 detects that the sensing signal generated on the first receiving element 103 is small or no sensing signal, so as to determine that the first receiving element 103 is worn seriously or worn completely. The fact that the magnitude of the electronic signal received by the first receiving element 103 decreases with the increase of the wear amount of the first receiving element 103 can also be understood that the first receiving element 103 receives the electronic signal when the first receiving element 103 is not worn, and the first receiving element 103 cannot receive the electronic signal or receives the electronic signal as zero after the first receiving element 103 is worn away.
In the embodiment of the present application, the electronic pen 10 is provided with a first receiving element 103, and the first receiving element 103 can be used for receiving an electronic signal between the pen tip 101 and the touch screen 201 of the electronic device 20. The magnitude of the electronic signal received by the first receiving element 103 decreases with the increase of the wear amount of the first receiving element 103, the signal detecting element 104 can detect the magnitude of the electronic signal on the first receiving element 103, and the detection result can make the user know the wear amount of the first receiving element 103, and because the first receiving element 103 is arranged in the pen point 102, the user can know the wear degree of the pen point 102. When the user knows that the pen point 102 is seriously worn, the user can replace the pen point 102 in time, so as to prevent the user from scratching the touch screen 201 by using the electronic pen 10 which is seriously worn. The pen point 102 is used for wrapping the pen point 101, the pen point 102 is used for contacting the touch screen 201, friction between the pen point 102 and the touch screen 201 is large in the using process, and the writing hand feeling can be improved.
In addition, the pen point 102 provided by the embodiment of the application is wrapped at one end of the pen point 101, so that the pen point 101 can be protected. Only the pen tip 102 needs to be replaced after the electronic pen 10 is worn, and the whole electronic pen 10 does not need to be replaced, so that the cost can be reduced.
Optionally, as shown in fig. 3, the first receiving element 103 comprises one or more metallic conductive wires. For example: gold, silver, copper, aluminum, etc. The number of the metal conductive wires can be selected according to the size of the pen tip 102, the performance of the metal conductive wires for receiving electronic signals, and the like. By arranging the first receiving element 103 as one or more metal conductive wires, the first receiving element 103 is easier to be worn off, so that the electronic signal received by the first receiving element 103 is better reduced along with the increase of the wear amount of the first receiving element 103.
Optionally, referring to fig. 1 and 6, the first receiving element 103 is arc-shaped, and the first receiving element 103 protrudes toward the first end surface 120 of the pen tip 102. In other words, the side of the first receiving element 103 facing the first end surface 120 is circular arc-shaped. By arranging the side of the first receiving element 103 facing the first end surface 120, the touch screen 201 can be prevented from being scratched when the first receiving element 103 receives the touch screen 201.
Further, referring to fig. 1 and 7, the electronic pen 10 further includes a pen barrel 105. The pen barrel 105 is sleeved on the second end 112 of the pen point 101. The pen barrel 105 and the pen point 102 are arranged at intervals. Specifically, the barrel 105 is spaced from the second end 122 of the tip 102. When the pen point 102 is pressed when writing on the touch screen 201, the first end surface 120 of the pen point 102 is close to the pen point 101 under the action of the pressing force, so as to reduce the distance between the pen point 101 and the touch screen 201, and facilitate the pen point 101 to receive scanning electronic signals emitted by the touch screen 201. The second end 122 of the tip 102 comes gradually closer to or into contact with the barrel 105 under the force of the squeezing force. By arranging the pen holder 105 and the second end surface 122 of the pen point 102 at intervals when no external force is applied, a certain space can be reserved for the pen point 102 to deform or move due to extrusion when writing.
The signal detection element 104 is provided in the barrel 105. Optionally, the signal detection element 104 is fixed within the barrel 105. The signal detection element 104 is connected to the first receiving element 103 through a conductive line.

The signal detection element 104 includes one or more of a current detection element, a resistance detection element, a voltage detection element, a charge detection element, and an electromagnetic detection element. For example, the signal detection element 104 may be a current sensor, a resistance measurement component, a voltage sensor, a capacitive sensor, an electromagnetic sensor, or the like.
When the first receiving element 103 receives an electronic signal transmitted from the touch screen 201 to the electronic pen 10 to generate an induced signal, the touch screen 201, the first receiving element 103 and the signal detecting element 104 form a signal transmission loop, and the signal receiving element 104 can be connected in series with the first receiving element 103 to detect the current on the first receiving element 103; alternatively, the signal receiving element 104 may be connected in parallel with the first receiving element 103 to detect the voltage magnitude on the first receiving element 103; still alternatively, the signal receiving element 104 may directly detect the magnitude of the resistance on the first receiving element 103 or directly detect the magnitude of the charge thereof; still alternatively, the signal detection element 104 may directly measure the magnetic induction intensity, the magnetic field intensity, and the like of the first reception element 103.
In addition, when the first receiving element 103 receives an electronic signal transmitted from the electronic pen 10 to the touch screen 201 via the pen tip 101 to generate an induced signal, the pen tip 101, the first receiving element 103 and the signal detecting element 104 form another signal transmission loop, and the signal receiving element 104 can detect an electrical signal or an electromagnetic signal of the loop.
