Description

Touch control pen and electronic equipment

Technical Field

The embodiment of the application relates to the technical field of terminals, in particular to a touch pen and electronic equipment.

Background

As electronic devices such as smart phones or tablet computers (PADs) have increased in explosive manner, the functions of the electronic devices have become more and more. The electronic device is equipped with a touch pen which is beneficial to operation and use besides the host computer. The user can execute part of the instructions, such as volume adjustment or brightness adjustment, through the stylus operating system. The user can also draw and write on the canvas of the electronic device using the stylus.

Because the stylus and the host computer are in a separated structure, the stylus falls from a high place under the non-use state to cause damage. The tip of the stylus typically needs to be in contact with the screen of the host computer. In order to obtain the touch accuracy, the volume of the pen tip of the stylus is usually designed to be small. In the related art, the pen point of the stylus is always exposed, so that the pen point of the stylus is relatively more easily damaged when the stylus drops. After the pen point of the touch pen is damaged, the touch pen cannot be used normally.

SUMMERY OF THE UTILITY MODEL

The embodiment of the application provides a touch control pen and electronic equipment, which can reduce the possibility that a pen point of the touch control pen is damaged due to impact.

The present application provides a touch pen, which at least includes a pen container, a pen core, an elastic member, a first magnetic member, a second magnetic member, a sensor and a stop member. The pen container comprises a holding part. At least part of the pen core is positioned in the pen container. The pen core is movably connected to the pen container along the axial direction of the pen container. The refill includes locking portion and nib. The elastic piece is arranged in the pen container. One end of the elastic piece is connected with the pen container, and the other end of the elastic piece is connected with the pen core. The first magnetic piece is fixedly arranged in the pen container. The second magnetic part is arranged on the pen core and corresponds to the first magnetic part. The sensor is arranged corresponding to the holding part. The stop piece is arranged in the pen container and is connected with the locking part. The stop piece is provided with a first locking position and a second locking position. When the sensor detects that fingers are placed on the holding part, the first magnetic part and the second magnetic part repel each other to drive the pen core to move and enable elastic potential energy of the elastic part to be increased. The locking part moves from the first locking position to the second locking position, and the pen point extends out of the pen container. When the sensor detects that fingers are not placed on the holding part, the first magnetic piece and the second magnetic piece repel each other to drive the pen core to move and release the elastic piece. The locking part moves from the second locking position to the first locking position, and the pen point retracts into the pen container.

The touch pen provided by the embodiment of the application can detect whether the fingers of a user are placed on the holding part of the touch pen through the sensor. If the sensor detects that the finger of the user is placed on the holding part, the first magnetic member and the second magnetic member can repel each other to move the second magnetic member and the pen core, so that the locking part of the pen core can be disengaged from the first locking position of the stop member and move to the second locking position to enable the pen point to extend out of the pen container. If the sensor detects that the finger of the user is not placed on the holding part, for example, the user puts down the touch control pen after using the touch control pen, the first magnetic piece and the second magnetic piece can repel each other to move the second magnetic piece and the pen core, so that the locking part of the pen core can be separated from the second locking position of the locking position piece and move to the first locking position under the pushing of the elastic piece to retract the pen core into the pen container. Therefore, the stylus pen of the embodiment of the application can retract into the pen container when being not used or accidentally separated from the fingers of a user, so that when the stylus pen accidentally drops, the stylus pen point of the stylus pen is not easy to collide with other objects, and the possibility of damage to the stylus pen point caused by collision is favorably reduced.

In one possible embodiment, at least one of the first magnetic member and the second magnetic member is an electromagnet, and the other is a permanent magnet. When the sensor detects that fingers are placed on the holding part or the sensor detects that the fingers of the holding part are removed, the electromagnet is electrified to generate a magnetic field, so that the first magnetic piece and the second magnetic piece are mutually repelled. When locking portion locking in first locking position or second locking position, the electro-magnet can be in the outage state, does not produce magnetic field, is favorable to reducing the consumption, prolongs the time of endurance of touch-control pen battery.

In one possible embodiment, the first magnetic member and the second magnetic member are both electromagnets. When the locking part is locked at the first locking position or the second locking position, the electromagnet can be in a power-off state, and a magnetic field is not generated, so that on one hand, the power consumption is favorably reduced, and the endurance time of a battery of the touch control pen is prolonged; on the other hand, the first magnetic part and the second magnetic part do not generate a magnetic field after being powered off, so that the possibility that the first magnetic part and the second magnetic part continuously generate the magnetic field to cause adverse effects on other electronic devices is favorably reduced.

The locking part does unidirectional motion in heart-shaped non-return groove section, guarantees that locking part motion process is steady, reduces reverse motion and leads to the possibility that the jamming appears.

In one possible embodiment, the barrel includes a front end. The elastic piece is arranged in the front end. The elastic piece is positioned on one side of the locking part facing the pen point. When the pen point extends out of the front end, the pen core compresses the elastic piece. The elastic piece is arranged in the front end of the pen container, so that the space formed between the front end of the pen container and the pen core can be used for arranging the elastic piece, the space utilization rate is improved, and the arrangement difficulty of the elastic piece can be reduced.

In one possible embodiment, the cartridge has a conical portion. The tapered portion is located between the locking portion and the nib. The elastic piece is conical and is sleeved on the conical part.

Detailed Description

The electronic device in the embodiment of the present application may be referred to as a User Equipment (UE) or a terminal (terminal), for example, the electronic device may be a mobile terminal or a fixed terminal such as a tablet computer (PAD), a Personal Digital Assistant (PDA), a handheld device having a wireless communication function, a computing device, a vehicle-mounted device, a wearable device, a Virtual Reality (VR) terminal device, an Augmented Reality (AR) terminal device, a wireless terminal in industrial control (industrial control), a wireless terminal in self driving (self driving), a wireless terminal in remote medical (remote medical), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation safety (transportation safety), a wireless terminal in smart city (smart city), a wireless terminal in smart home (smart home), and the like. The form of the terminal device in the embodiment of the present application is not particularly limited.

In the embodiment of the present application, fig. 1 schematically shows a structure of an electronic device 10 according to an embodiment. Referring to fig. 1, an electronic device 10 is illustrated as a handheld device having a wireless communication function. The wireless communication enabled handheld device may be a cell phone, for example.

Fig. 2 schematically shows a partially exploded structure of the host. Referring to fig. 1 and 2, the electronic device 10 includes a host 20 and a stylus 30. The host 20 of the embodiment of the present application includes a touch screen 21, a housing 22, a motherboard 23, and an electronic device 24. The touch screen 21 has a display area for displaying image information. The touch screen 21 is mounted to the housing 22, and a display area of the touch screen 21 is exposed to facilitate presentation of image information to a user. The main board 23 is connected to the housing 22 and located inside the touch screen 21, so that the main board 23 is not easily visible to a user outside the electronic device 10. The electronic device 24 is provided on the main board 23. The main Board 23 may be a Printed Circuit Board (PCB). For example, the electronic device 24 is soldered to the main board 23 by a soldering process. The electronic device 24 includes, but is not limited to, a Central Processing Unit (CPU), a smart algorithm chip, or a Power Management IC (PMIC).

Wireless signal interaction between host 20 and stylus 30 may be implemented through a bluetooth network or a Near Field Communication (NFC) network, thereby facilitating free movement of stylus 30 without being constrained by a wire harness. The stylus 30 may perform related operations on the touch screen 21 of the host 20, such as character input, clicking or drawing. The stylus 30 can also be used to remotely operate the host 20, such as unlocking or locking the host 20, answering or hanging up an incoming call, etc. The stylus 30 may have a cylindrical structure having a predetermined length so that the user can more easily hold the stylus 30.

In some implementations, stylus 30 may be an inductive stylus. When the stylus 30 is an inductive pen, an electromagnetic induction board needs to be integrated on the touch screen 21 for interacting with the stylus 30. The electromagnetic induction board is distributed with coils, and the inductance pen is also integrated with the coils. Based on the electromagnetic induction principle, the inductive pen can accumulate electric energy along with the movement of the inductive pen in the magnetic field range generated by the electromagnetic induction plate. The inductance pen can transmit the accumulated electric energy to the electromagnetic induction plate through free oscillation and a coil in the inductance pen. The electromagnetic induction board can scan the coil on the electromagnetic induction board based on the electric energy from the inductive pen, and calculate the position of the inductive pen on the touch screen 21.

In some implementations, the stylus 30 can be a capacitive stylus. The capacitive stylus may include: passive capacitive pens and active capacitive pens. The passive capacitive stylus may be referred to as a passive capacitive stylus and the active capacitive stylus may be referred to as an active capacitive stylus. When stylus 30 is an active capacitive pen, one or more electrodes can be disposed in the active capacitive pen (e.g., in the pen tip). The active capacitive stylus may transmit a signal through the electrode. When stylus 30 is an active capacitance stylus, an integrated electrode array is required on the touch screen 21 to interact with stylus 30. In one embodiment, the electrode array may be a capacitive electrode array. The electronic device 10 may receive a signal from the active capacitive stylus through the electrode array, and thus, when receiving the signal, identify a position of the active capacitive stylus on the touch screen 21 and a tilt angle of the active capacitive stylus based on a change in a capacitance value on the touch screen 21.

The following explains an implementation of the stylus 30 provided in the embodiment of the present application.

Fig. 3 schematically shows the overall structure of the stylus 30 according to an embodiment. FIG. 4 schematically illustrates a partial perspective structure of a stylus 30 according to an embodiment. Referring to fig. 3 to 5, a stylus pen 30 according to an embodiment of the present invention includes a pen container 31, a pen core 32, an elastic member 33, a first magnetic member 34, a second magnetic member 35, a sensor 36, and a stopper 37.

The barrel 31 may be a bar body having a long bar shape. The barrel 31 includes a grip 311. When a user performs a writing or clicking operation using the stylus 30, the user's fingers are generally held within a predetermined area of the barrel 31. The grip 311 on the barrel 31 is used to facilitate the placement of fingers by the user. The grip portion 311 may be differentiated from other areas in terms of color or structure in order to facilitate the user to conveniently observe and contact the grip portion 311. At least part of the pen core 32 is positioned in the pen container 31, so that the pen container 31 can protect the pen core 32 and reduce the possibility of collision damage of the pen core 32. The cartridge 32 is movably coupled to the barrel 31 in an axial direction X of the barrel 31 so as to be movable relative to the barrel 31 when the cartridge 32 is subjected to a force in the axial direction X. The cartridge 32 includes a locking portion 321 and a pen tip 322. The pen tip 322 of the pen core 32 may be in direct contact with the touch screen 21 of the host 20 to write on the touch screen 21 or click a function icon on the touch screen 21.

The elastic member 33 is disposed in the barrel 31. The elastic member 33 has one end connected to the barrel 31 and the other end connected to the cartridge 32. The elastic member 33 refers to a device that can be compressed or stretched by an external force to accumulate elastic potential energy, and can release the elastic potential energy when the external force is removed.

The first magnetic member 34 is fixedly disposed in the barrel 31, so that the relative position of the first magnetic member 34 and the barrel 31 is fixed and does not move along the axial direction X of the barrel 31. The second magnetic member 35 is provided at the pen core 32 and is provided corresponding to the first magnetic member 34. The first magnetic member 34 is disposed facing the second magnetic member 35 in the axial direction X of the barrel 31. When the pen core 32 moves in the axial direction X of the barrel 31, the second magnetic member 35 may move synchronously with the pen core 32 in the barrel 31.

The sensor 36 is provided corresponding to the grip 311 of the pen barrel 31. The sensor 36 is configured to detect whether or not a finger of the user is placed on the grip portion 311, and can output a corresponding electric signal.

Referring to fig. 4 and 5, the stopper 37 is provided in the barrel 31 and connected to the locking portion 321 of the cartridge 32. The stop member 37 has a first locking position 371 and a second locking position 372. The first locking position 371 and the second locking position 372 are arranged at intervals along the axial direction X of the pen container 31. The first locking position 371 is located on a side of the second locking position 372 opposite to the pen tip 322. The locking portion 321 of the pen core 32 is configured to switch between a first locking position 371 and a second locking position 372. When the locking part 321 is at the first locking position 371 or the second locking position 372, the relative position of the pen core 32 and the pen container 31 is kept unchanged. When the locking part 321 is at the second locking position 372, the pen point 322 of the pen core 32 is in a state of extending out of the pen container 31. Fig. 6 schematically shows a partial structure of the stylus 30 according to an embodiment. Referring to fig. 6, when the locking portion 321 is at the first locking position 371, the pen tip 322 of the pen core 32 is in a state of being retracted into the pen barrel 31.

When the sensor 36 detects that fingers are placed on the grip portion 311, the first magnetic member 34 is configured to repel the second magnetic member 35, so as to move the pen core 32 and increase the elastic potential energy of the elastic member 33. When the pen core 32 moves, the elastic member 33 may be compressed or stretched, so that the elastic potential energy of the elastic member 33 is increased. The locking portion 321 of the cartridge 32 moves from the first locking position 371 to the second locking position 372, and the writing tip 322 of the cartridge 32 extends out of the barrel 31. The resilient member 33 may provide a force to the cartridge 32 to maintain the locking portion 321 in the second locked position 372. At this time, the user can use the stylus 30 to write normally or click on the function icon.

When the sensor 36 detects that no finger is placed on the grip portion 311, the first magnetic member 34 is configured to repel the second magnetic member 35, so as to move the pen core 32 and disengage the locking portion 321 from the second locking position 372. The cartridge 32 releases the elastic member 33. The elastic member 33 releases its own elastic potential energy so that the cartridge 32 can be urged in the axial direction X of the barrel 31. At this time, the locking portion 321 moves from the second locking position 372 to the first locking position 371, and the nib 322 of the cartridge 32 retracts into the barrel 31. The elastic member 33 may provide a force to the pen core 32 to maintain the locking portion 321 at the first locking position 371. At this time, the pen tip 322 is positioned in the barrel 31 so that the barrel 31 can protect the pen tip 322.

When the first magnetic member 34 and the second magnetic member 35 repel each other, a driving force may be provided to the pen core 32 to move the pen core 32, so that the locking portion 321 of the pen core 32 may disengage from the first locking position 371 or the second locking position 372.

In the stylus 30 according to the embodiment of the present application, the sensor 36 can detect whether the finger of the user is placed on the holding portion 311 of the stylus 30. If the sensor 36 detects that the user's finger is placed on the grip 311, the first magnetic member 34 and the second magnetic member 35 may repel each other to move the second magnetic member 35 and the pen core 32, so that the locking portion 321 of the pen core 32 may be disengaged from the first locking position 371 of the locking member 37 and moved to the second locking position 372 to extend the pen tip 322 out of the pen barrel 31. If the sensor 36 detects that no finger of the user is placed on the grip 311, for example, the user puts down the stylus 30 after using the stylus 30, the first magnetic member 34 and the second magnetic member 35 may repel each other to move the second magnetic member 35 and the pen core 32, so that the locking portion 321 of the pen core 32 may be disengaged from the second locking position 372 of the stopper 37 and move to the first locking position 371 under the urging of the elastic member 33 to retract the pen tip 322 into the pen container 31. Therefore, the stylus pen 30 of the embodiment of the application can retract the pen point 322 into the pen container 31 when the stylus pen 30 is not used or accidentally drops off from the finger of the user, so that the pen point 322 of the stylus pen 30 is not easy to collide with other objects when the stylus pen 30 accidentally drops, and the possibility of damage caused by collision of the pen point 322 of the stylus pen 30 is reduced.

In some realizable forms, at least one of the first and second

magnetic members

34, 35 is an electromagnet. When the sensor 36 detects that a finger is placed on the grip portion 311 or the sensor 36 detects that the finger of the grip portion 311 is removed, the electromagnet is energized to generate a magnetic field, so that the first magnetic member 34 and the second magnetic member 35 are repelled from each other. When locking portion 321 locked in first locking position 371 or second locking position 372, the electro-magnet can be in the outage state, does not produce magnetic field, is favorable to reducing the consumption, prolongs the time of endurance of stylus 30 battery. In some examples, at least one of the first and second

magnetic pieces

34 and 35 is an electromagnet and the other is a permanent magnet. After the electromagnet is electrified, the magnetic pole of the electromagnet close to the permanent magnet is the same as that of the permanent magnet close to the electromagnet, so that the electromagnet and the permanent magnet can be mutually exclusive. Illustratively, the first magnetic member 34 is a permanent magnet, and the second magnetic member 35 is an electromagnet.

In other implementations, the first and second

magnetic members

34 and 35 are electromagnets. When the sensor 36 detects that a finger is placed on the grip portion 311 or the sensor 36 detects that the finger of the grip portion 311 is removed, the electromagnet is energized to generate a magnetic field. After the electromagnet is electrified, the electromagnet and the electromagnet are mutually exclusive. When the locking portion 321 is locked at the first locking position 371 or the second locking position 372, the electromagnet may be in a power-off state, and no magnetic field is generated, which is beneficial to reducing power consumption and prolonging the endurance time of the battery of the stylus 30; on the other hand, after the first magnetic member 34 and the second magnetic member 35 are powered off, no magnetic field is generated, which is beneficial to reducing the possibility that the first magnetic member 34 and the second magnetic member 35 continuously generate a magnetic field to cause adverse effects on other electronic devices 24.

In some realizable forms, the sensor 36 is a capacitive sensing device. When the user's fingers are placed on the grip portion 311 or removed from the grip portion 311, the capacitance signal of the sensor 36 is changed. The sensor 36 can realize non-contact measurement and has high sensitivity, so that the sensor 36 can be disposed in the pen container 31 of the stylus 30, and whether or not the finger is placed on the grip portion 311 can be accurately detected.

In some examples, the sensor 36 is a thin film capacitor. The film capacitor may be attached to the outer circumference of the pen core 32. The thin film capacitor has a small thickness, and thus occupies a small internal space of the stylus 30, which is beneficial to reducing the difficulty in arranging the sensor 36, and can also improve the structural compactness of the stylus 30.

Illustratively, as shown in fig. 4, the film capacitor forms a cylinder body to cover the pen core 32 along the circumferential direction of the pen barrel 31, so that the film capacitor is arranged around the pen core 32 for a full circle, thereby being beneficial to enlarging the detection range of the sensor 36 and improving the detection accuracy. Therefore, when the user's fingers are in contact with any area of the grip portion 311 or when the user's fingers are removed from any area of the grip portion 311, the sensor 36 can accurately detect these changes and generate corresponding electrical signals.

In some realizable ways, fig. 7 schematically illustrates the structure of the stop 37 of an embodiment. Referring to fig. 6 and 7, the stopper 37 is provided on the inner wall of the barrel 31. The stopper 37 has a track-restricting groove. The track limiting groove includes a first locking position 371 and a second locking position 372. The trajectory limiting groove includes a heart-shaped non-return groove section 373 and a straight groove section 374. The heart-shaped check groove section 373 has a first tip portion 373a and a second tip portion 373 b. The first tip portion 373a and the second tip portion 373b are spaced apart from each other in the axial direction X of the barrel 31. The first tip portion 373a is disposed away from the pen tip 322 of the pen core 32. The second tip portion 373b is located on the side of the first tip portion 373a facing the pen tip 322 of the pen core 32. The straight groove section 374 is located on the side of the heart-shaped non-return groove section 373 facing away from the pen tip 322 of the cartridge 32. The straight groove section 374 communicates with the first tip portion 373 a. A region of the straight groove section 374 remote from the second tip portion 373b forms a first locking bit 371. The second tip portion 373b forms a second locking position 372. The locking portion 321 is a convex column. When the cartridge 32 moves in the barrel 31, the locking portion 321 is configured to move along the heart-shaped check groove section 373 and the straight groove section 374 to switch between the first locking position 371 and the second locking position 372. Locking portion 321 makes unidirectional motion in heart-shaped non return groove section 373, guarantees that locking portion 321 motion process is steady, reduces reverse motion and leads to appearing the possibility of jamming.

When the locking portion 321 is at the first locking position 371 and the first magnetic member 34 and the second magnetic member 35 repel each other, the locking portion 321 moves away from the first locking position 371. The locking portion 321 moves to the second locking position 372 along the straight groove section 374 and a portion of the heart-shaped non-return groove section 373 by the repulsive force of the first and second

magnetic members

34 and 35. When the locking position is locked at the second locking position 372, the pen point 322 extends out of the pen container 31, and the elastic piece 33 accumulates larger elastic potential energy under the action of the pen core 32. When the first magnetic member 34 and the second magnetic member 35 repel each other again, the locking portion 321 moves away from the second locking position 372. The elastic member 33 releases its own elastic potential energy to apply a driving force to the pen core 32. The locking portion 321 moves along another portion of the heart check groove segment 373 into the straight groove segment 374, and then moves along the straight groove segment 374 to the first locking position 371. When the locking position is locked at the first locking position 371, the pen tip 322 is retracted into the pen barrel 31.

In some realizable forms, the barrel 31 is a rod-like structure. The barrel 31 further includes a front end 312 and a rear end 313. The front end 312 and the rear end 313 are oppositely arranged along the axial direction X of the pen container 31. The grip portion 311 is located between the leading end 312 and the trailing end 313 and is disposed proximate the leading end 312. The first magnetic member 34 may be disposed at the tail end 313 of the barrel 31, and the second magnetic member 35 may be disposed at the tail of the pen core 32. The tip 322 of the cartridge 32 is disposed opposite to the tail of the cartridge 32 in the axial direction X of the barrel 31. The elastic member 33 is disposed in the front end 312 of the barrel 31, so that the elastic member 33 can be disposed by using a space formed between the front end 312 of the barrel 31 and the pen core 32, which is beneficial to improving space utilization rate and reducing difficulty in arrangement of the elastic member 33. The elastic member 33 is located on a side of the locking portion 321 facing the pen tip 322. The elastic member 33 has one end connected to the cartridge 32 and the other end connected to the front end 312 of the barrel 31. When the pen tip 322 extends out of the front end 312, the pen core 32 may compress the elastic member 33 to increase the elastic potential energy of the elastic member 33. During retraction of the writing tip 322 into the front end 312, the writing core 32 releases the elastic member 33, so that the elastic member 33 can push the writing core 32 to move towards the rear end 313 of the barrel 31.

In some examples, cartridge 32 has a tapered portion 323. The tapered portion 323 is located between the locking portion 321 and the pen tip 322. The elastic member 33 is tapered and is sleeved on the tapered portion 323 of the pen core 32. The end of the elastic member 33 near the pen tip 322 can directly press against the front end 312 of the barrel 31. The conical part 323 of the pen core 32 can limit the elastic part 33, so that no additional limiting part is required to be arranged on the pen core 32, the processing difficulty of the pen core 32 is reduced, and the assembly difficulty of the elastic part 33 and the pen core 32 is reduced. Illustratively, the elastic member 33 is a coil spring. The inner wall of the front end 312 of the barrel 31 is tapered. Illustratively, the sensor 36 is a thin film capacitor. The process of assembling the stylus 30 may include: the sensor 36 is fixed around the outer periphery of the pen core 32. The second magnetic member 35 is disposed at the tail of the pen core 32. The elastic member 33 is fitted over the tapered portion 323 of the pen core 32. The cartridge 32 provided with the sensor 36, the second magnetic member 35 and the elastic member 33 is inserted into the barrel 31. The first magnetic member 34 is disposed at the tail end 313 of the barrel 31. The first magnetic member 34 may be adhesively fixed using an adhesive.

In some realizable manners, the number of the locking portions 321 is two or more. The number and positions of the locking portions 321 are provided in one-to-one correspondence with the number and positions of the stopper 37. Along the circumferential direction of the pen container 31, more than two locking parts 321 are uniformly arranged at intervals, so that the more than two locking parts 321 respectively form limit constraint on the pen core 32, the stress balance of the pen core 32 can be ensured, and the possibility of deflection of the pen core 32 in the pen container 31 is reduced. Illustratively, the number of the locking portions 321 is two. The number of the stopper 37 is two. The two locking portions 321 are symmetrically disposed. The two stop members 37 are symmetrically arranged.

In some implementations, FIG. 8 schematically illustrates a partially exploded structure of the stylus 30 of an embodiment. Referring to fig. 8, the pen core 32 has a stopper 324. The limiting block 324 is spaced from the locking portion 321 along the axial direction X of the pen barrel 31. The limiting block 324 abuts against the inner wall of the pen container 31, so that when the pen core 32 moves relative to the pen container 31, the limiting block 324 can reduce the possibility that the pen core 32 deflects in the pen container 31, and ensure that the moving process of the pen core 32 is smooth and stable. In some examples, fig. 9 schematically illustrates a partial cross-sectional structure of a stylus 30 of an embodiment. Referring to fig. 9, the barrel 31 has a guide groove 314. The guide groove 314 extends in the axial direction X of the barrel 31. At least a portion of the stopper 324 of the pen core 32 is located in the guide groove 314. When the pen core 32 moves relative to the pen container 31, the stopper 324 can move along the track defined by the guide groove 314.

In some implementations, a battery (not shown) may be disposed inside the stylus pen, so that the power required by the stylus pen can be supplied from the battery without an external power source, the stylus pen can be used alone conveniently, and the range of motion is not limited by a lead connected to the power source.
