The stylus can be a capacitive stylus, which has accurate positioning capability and low latency. The stylus can match a signal with the electronic device, and thus realize operation on the matched electronic device.

[0003] However, the stylus in the related art can match only a single type of electronic device, which affects the application range and practicability of the stylus. CONTENT OF THE INVENTION

[0006] a nib assembly configured to send a matching signal to an electronic device to determine a writing track of the electronic device;

[0007] a pen barrel having a first cavity, the nib assembly being rotatable relative to the pen barrel about a first axis;

[0008] a control assembly arranged in the first cavity;

[0009] a first switch and a second switch, both electrically connected to the control assembly, the first switch and the second switch being arranged at intervals along a rotation direction of the nib assembly;

[0010] when the nib assembly triggers the first switch by rotation, the control assembly sends a first matching signal to the nib assembly;

[0011] when the nib assembly triggers the second switch by rotation, the control assembly sends a second matching signal to the nib assembly;

[0012] the first matching signal and the second matching signal are used to adapt to different electronic devices.

[0013] The application provides a stylus, a pen tip assembly is electrically connected with a control assembly, and the pen tip assembly can send a matching signal to an electronic device to make the electronic device determine a writing track, so that the stylus is used for writing operation of the electronic device. The pen tip assembly and the pen barrel are rotationally connected, the pen tip assembly can rotate relative to the pen barrel around a first axis, and the pen tip assembly can trigger a first switch or a second switch electrically connected with the control assembly through rotation. When the first switch and the second switch are triggered by the pen tip assembly, the control assembly can send a first matching signal and a second matching signal adapted to different electronic devices to the pen tip assembly, so that the stylus can switch the matching signal matched with different electronic devices, one stylus can be applied to electronic devices with different matching signals, and the application range and practicability of the stylus are improved.

[0014] On the basis of the above-mentioned embodiments, the application also has the following improvements:

[0015] In a possible implementation, an end of the first cavity towards the pen tip assembly has a mounting structure;

[0016] An annular groove is formed between the outer peripheral wall of the mounting structure and the inner peripheral wall of the first cavity, and the groove opening of the annular groove communicates the inside and outside of the first cavity;

[0017] The mounting structure has a second cavity, and at least part of the control assembly is arranged in the second cavity;

[0018] The first switch and the second switch are both connected with the control assembly through the wall surface of the mounting structure;

[0019] The pen tip assembly comprises a trigger piece, the trigger piece is located in the annular groove, and the trigger piece rotates along the extension path of the annular groove and is used for triggering the first switch or the second switch.

[0020] In this way, the mounting structure can be used for protecting the control assembly, avoiding interference of other components in the first cavity on the control assembly, and avoiding collision damage of other components in the first cavity on the control assembly. In addition, the mounting structure can be used for limiting and fixing the control assembly, avoiding shaking of the control assembly in the pen barrel.

[0021] The first switch and the second switch are connected with the control assembly through the wall surface of the mounting structure, which can improve the connection stability of the first switch and the second switch and the control assembly, avoid shaking of the first switch and the second switch, and avoid triggering failure of the first switch and the second switch due to shaking of the first switch or the second switch when the pen tip assembly triggers the first switch and the second switch.

[0022] Further, the pen tip assembly extends into the annular groove by using the trigger, and the annular groove guides the trigger to rotate circumferentially along the first axis, avoiding deviation and shaking of the trigger during rotation, improving the stability of the trigger during rotation, and further improving the structural stability of the stylus.

[0023] In a possible implementation, the trigger has a first protrusion for pressing the first switch when rotated to the first switch.

[0024] The trigger also has a second protrusion for pressing the second switch when rotated to the second switch.

[0025] In this way, by arranging the first protrusion on the trigger on the side facing the first switch, the first switch can be triggered by the first protrusion, and the accuracy and stability of triggering the first protrusion by the trigger can be improved, avoiding failure of the trigger to trigger the first switch.

[0026] In a possible implementation, the first switch includes:

[0027] The first key has a first abutting portion and a first contact point, the first abutting portion abuts the pen tip assembly, and the first contact point is arranged to be spaced apart from the control assembly.

[0028] When the pen tip assembly is rotated to the first abutting portion, the first contact point is electrically connected to the control assembly by pressing the first abutting portion.

[0029] In this way, by arranging the first abutting portion and the first contact point on the first key, the structure of the first switch can be simplified, the manufacturing cost of the first switch can be reduced, and the manufacturing cost of the stylus can be further reduced. When the first switch is not triggered, the first contact point is arranged to be spaced apart from the control assembly, which can avoid false triggering of the first key and improve the working stability of the first switch.

[0030] In a possible implementation, the first switch further includes:

[0031] The first conductive member is arranged on the side of the first contact point facing the control assembly.

[0032] The second conductive member is arranged on the side of the control assembly facing the first conductive member.

[0033] The first key is electrically connected to the control assembly through the first conductive member and the second conductive member.

[0034] In this way, the first switch sends a signal to the control assembly by the contact of the first conductive member and the second conductive member, which can simplify the structure of the first switch, improve the assembly efficiency between the first switch and the control assembly, and further improve the assembly efficiency of the stylus while reducing the manufacturing cost of the stylus.

[0035] In a possible implementation, the second switch comprises:

[0036] The second key has a second abutting portion and a second contact point, the second abutting portion is used for abutting the nib assembly, and the second contact point is arranged to be spaced apart from the control assembly.

[0037] When the nib assembly rotates to the second abutting portion, the second contact point is electrically connected to the control assembly by extruding the second abutting portion.

[0038] In this way, the second switch sends a signal to the control assembly by the contact of the first conductive member and the second conductive member, which can simplify the structure of the first switch, improve the assembly efficiency between the first switch and the control assembly, and further improve the assembly efficiency of the stylus while reducing the manufacturing cost of the stylus.

[0039] In a possible implementation, the second switch further comprises:

[0040] The third conductive member is arranged on the side of the second contact point facing the control assembly.

[0041] The fourth conductive member is arranged on the side of the control assembly facing the third conductive member.

[0042] The second key electrically connects the control assembly through the third conductive member and the fourth conductive member.

[0043] In this way, the second switch sends a signal to the control assembly by the contact of the first conductive member and the second conductive member, which can simplify the structure of the first switch, improve the assembly efficiency between the first switch and the control assembly, and further improve the assembly efficiency of the stylus while reducing the manufacturing cost of the stylus.

[0044] In a possible implementation, the first key is a first elastic member; and / or the second key is a second elastic member.

[0045] In this way, by setting the first button as the first elastic member, the first button can control the disconnection and electrical connection between the first switch and the control assembly by elastic deformation, avoiding the first switch from using additional structures to control the connection state between the first button and the control assembly, thereby simplifying the structure of the first switch, and further improving the assembly efficiency of the first switch and the stylus.

[0046] In this way, by setting the second button as the second elastic member, the second button can control the disconnection and electrical connection between the second switch and the control assembly by elastic deformation, avoiding the second switch from using additional structures to control the connection state between the second button and the control assembly, thereby simplifying the structure of the second switch, and further improving the assembly efficiency of the second switch and the stylus.

[0047] In a possible implementation, the stylus further comprises a clamping member;

[0048] The trigger member is provided with an annular clamping groove on the surface facing the mounting structure, and the annular clamping groove is concentric with the annular groove.

[0049] The clamping member is arranged on the outer side wall of the mounting structure facing the trigger member, and the clamping member is located in the annular clamping groove.

[0050] In this way, by arranging the clamping member in the annular clamping groove, when the trigger member rotates, the clamping member can rotate along the extension path of the annular clamping groove, and the annular clamping groove can prevent the clamping member from separating from the pen barrel along the direction of the first axis, thereby improving the connection stability between the trigger member and the pen barrel, and further improving the connection stability between the nib assembly and the pen barrel.

[0051] In addition, the annular clamping groove can guide the clamping member to rotate along the extension path of the annular clamping groove to guide the nib assembly to rotate around the first axis, thereby improving the accuracy and stability of the rotation of the nib assembly relative to the pen barrel.

[0052] In a possible implementation, the clamping member is a clamping block, and the clamping block is arranged on the outer edge surface of the mounting structure and located in the annular clamping groove.

[0053] In this way, by setting the clamping member as a clamping block, the structure of the clamping block is relatively simple and easy to assemble, and the manufacturing cost is relatively low, thereby reducing the manufacturing cost of the clamping member on the basis of simplifying the structure of the clamping member, and reducing the manufacturing cost of the stylus on the basis of improving the assembly efficiency of the stylus.

[0054] In a possible implementation, the clamping member is a third elastic member, and the third elastic member has a connecting portion and a protruding portion.

[0055] The connecting portion is arranged on the side wall of the mounting structure facing the trigger; and the protruding portion is elastically deformed along the radial direction of the first axis and located in the annular clamping groove.

[0056] In this way, by arranging the clamping piece as the third elastic piece, and connecting the third elastic piece with the side wall of the mounting structure through the connecting portion, and by arranging the protruding portion in the annular clamping groove and elastically deforming the protruding portion along the radial direction of the first axis, the protruding portion can reduce the vibration caused by the collision with the annular clamping groove by elastic deformation when being pressed by the annular clamping groove, thereby improving the use comfort of the pen tip assembly during rotation.

[0057] In addition, the elastic contact between the protruding portion of the third elastic piece and the wall of the annular clamping groove can reduce the contact friction between the clamping piece and the annular clamping groove, so that the rotation of the pen tip assembly is smoother, and the use comfort of the stylus is improved.

[0058] In addition, the third elastic piece can dynamically adjust the contact pressure between the protruding portion and the annular clamping groove during rotation according to the force condition, so as to avoid the jamming or loosening between the pen tip assembly and the pen barrel caused by excessive or insufficient pressure.

[0059] In a possible implementation, the outer side wall of the mounting structure facing the trigger is provided with a mounting groove, the connecting portion of the third elastic piece is arranged in the mounting groove, and the protruding portion protrudes out of the mounting groove and is located in the annular clamping groove.

[0060] In this way, by arranging the connecting portion of the third elastic piece in the mounting groove, the third elastic piece can occupy less space in the radial direction of the first axis in the internal space of the first cavity of the pen barrel, thereby helping to improve the utilization rate of the internal space of the first cavity.

[0061] In addition, by arranging the connecting portion of the third elastic piece in the mounting groove, the side wall of the mounting groove can limit the connecting portion, so as to improve the mounting stability of the third elastic piece on the mounting structure, and further improve the structural stability of the stylus.

[0062] In a possible implementation, the pen tip assembly includes a first electrode;

[0063] One end of the first electrode is electrically connected to the control assembly, and the first electrode rotates relative to the control assembly.

[0064] When the trigger triggers the first switch by rotation, the control assembly sends a first matching signal to the first electrode;

[0065] When the trigger triggers the second switch by rotation, the control assembly sends a second matching signal to the first electrode.

[0066] The first electrode is configured to transmit the first matching signal or the second matching signal to the electronic device, and to enable the electronic device to determine the writing track.

[0067] In this way, the first electrode can transmit the first matching signal or the second matching signal transmitted by the control assembly to the electronic device, so as to enable the electronic device to determine the writing track.

[0068] In a possible implementation, the pen tip assembly further comprises a buffer assembly.

[0069] One end of the buffer assembly is abutted against one end of the first electrode towards the control assembly, and the other end of the buffer assembly is abutted against the control assembly; the buffer assembly is configured to slow down the impact of the first electrode transmitted to the control assembly.

[0070] In this way, the first electrode is electrically connected to the control assembly through the buffer assembly, and the buffer assembly is in a pre-compressed state, so that the first electrode can be kept in an electrically connected state with the control assembly while ensuring rotation of the first electrode relative to the control assembly, thereby avoiding the problem of disconnection between the first electrode and the control assembly.

[0071] In a possible implementation, the buffer assembly comprises a first electrical connector, a second electrical connector and a pre-compression spring.

[0072] One end of the first electrical connector is abutted against the first electrode, and the other end of the first electrical connector is connected to the pre-compression spring; the second electrical connector is connected to one end of the pre-compression spring away from the first electrical connector, and the other end of the second electrical connector passes through the mounting structure and is abutted against the control assembly.

[0073] In this way, by configuring the buffer assembly as the first electrical connector, the pre-compression spring and the second electrical connector, the first electrical connector and the second electrical connector can be spaced apart in the first axis direction, so that when the pen tip assembly is pressed towards the pen barrel, the first electrical connector and the second electrical connector can further approach each other, so that the pre-compression spring can be further compressed.

[0074] By comprising the first electrical connector, the second electrical connector and the pre-compression spring, the buffer assembly can simplify the structure of the buffer assembly, improve the assembly efficiency of the buffer assembly, and simplify the structure of the stylus and improve the assembly efficiency of the stylus.

[0075] In a possible implementation, the pen tip assembly further comprises a second electrode.

[0076] The second electrode is arranged around the outer periphery of the first electrode, the second electrode is electrically connected to the control assembly, and the second electrode rotates together with the first electrode.

[0077] The control assembly sends a third matching signal to the second electrode when the trigger triggers the first switch by rotating;

[0078] The control assembly sends a fourth matching signal to the second electrode when the trigger triggers the second switch by rotating;

[0079] The second electrode sends the third matching signal or the fourth matching signal to the electronic device to determine the tilt angle of the stylus.

[0080] In this way, by arranging the second electrode, the tilt angle of the stylus can be detected at any time while ensuring that the stylus can write on the electronic device, so that the electronic device corrects the feedback position according to the recognized angle, thereby improving the interactive experience of the user during use.

[0081] In a possible implementation, the control assembly comprises:

[0082] The circuit board assembly is arranged in the first cavity and electrically connected to the nib assembly, and the first switch and the second switch are arranged on the circuit board assembly;

[0083] The signal processing unit is arranged on the circuit board assembly, and the signal processing unit is configured to send the first matching signal and the second matching signal to the nib assembly according to the electrical signals sent by the first switch and the second switch.

[0084] In this way, the control assembly comprises the circuit board assembly and the signal processing unit, the circuit board assembly can electrically connect the first switch, the second switch and the signal processing unit, and the signal processing unit can transmit signals to the first electrode or the second electrode of the nib assembly.

[0085] In a possible implementation, the circuit board assembly comprises:

[0086] The first circuit board is arranged in the second cavity of the mounting structure, and the first circuit board is configured to electrically connect the nib assembly, and the first switch and the second switch are arranged on the first circuit board;

[0087] The second circuit board is electrically connected to the first circuit board, and the signal processing unit is arranged on the second circuit board.

[0088] In this way, by setting up a first circuit board and a second circuit board that are electrically connected to each other, the first circuit board is connected to the first switch and the second switch, and the first circuit board is electrically connected to the pen tip assembly. The second circuit board is used to set up a signal processing unit, which makes it easy to repair and replace the first switch, the second switch and the pen tip assembly individually, and also makes it easy to repair and replace the signal processing unit individually.

[0089] Furthermore, the size of the first circuit board can be smaller than that of the second circuit board. This allows the first circuit board to be placed inside the second cavity, while the larger size of the second circuit board allows for the placement of more electronic components, thus enriching the functions of the stylus.

[0090] In one possible implementation, the circuit board assembly further includes a flexible circuit board;

[0091] One end of the flexible circuit board is electrically connected to the first circuit board, and the other end of the flexible circuit board is used to electrically connect to the second circuit board.

[0092] In this way, by including a flexible circuit board and electrically connecting the first and second circuit boards through the flexible circuit board, the circuit board assembly can avoid the problem that the connection between the first and second circuit boards is easily damaged by impact when the first and second circuit boards are directly rigidly connected, thus improving the durability of the circuit board assembly.

[0093] A second aspect of this application provides an electronic device including a touch screen and a stylus as described above.

[0094] In this way, the electronic device can include a touchscreen and a processor capable of transmitting signals to the touchscreen. The processor establishes a signal transmission with the stylus to facilitate pairing of the stylus with the electronic device. Furthermore, the processor can control the touchscreen to display the writing trajectory of the stylus based on the pairing signal sent by the stylus. This enables operation of the touchscreen via a stylus, improving the ease of use of the electronic device. Attached Figure Description

[0125] The electronic device includes, but is not limited to, a mobile phone (for example, a straight mobile phone or a foldable mobile phone), a tablet computer, a notebook computer, an ultra-mobile personal computer (UMPC for short), a handheld computer, a walkie-talkie, a network television, a television, a vehicle-mounted device, a netbook, a POS machine, a personal digital assistant (PDA for short), a wearable device (for example, a smart watch, a smart wristband, and the like), and a mobile or fixed terminal having a touch screen that can be operated by a stylus.

[0126] The stylus in the prior art can match a relatively single electronic device, which affects the application range of the stylus.

[0127] The reason for this problem is that different types of electronic devices in the prior art have different matching signals, and the different matching signals can be different coding protocols. The existing stylus only has one matching signal. For example, a first electronic device has a first matching signal, a second electronic device has a second matching signal, and the stylus only has a matching signal that is adapted to the first matching signal. The stylus can be used for the first electronic device, but when the stylus is used for the second electronic device, the matching signal of the stylus cannot be adapted to the second matching signal, which causes the stylus to be unable to be used on the second electronic device, thereby causing the stylus to be able to match a relatively single electronic device, which affects the application range and practicality of the stylus.

[0128] In order to solve the above technical problems, the application provides a stylus and an electronic device, the pen tip assembly is electrically connected with the control assembly, and the pen tip assembly can send a matching signal to the electronic device to determine a writing track, so as to realize the writing operation of the stylus on the electronic device. The pen tip assembly and the pen barrel are rotationally connected, the pen tip assembly can rotate relative to the pen barrel around a first axis, and the pen tip assembly can trigger the first switch or the second switch electrically connected with the control assembly through rotation. When the first switch and the second switch are triggered by the pen tip assembly, the control assembly can send a first matching signal and a second matching signal suitable for different electronic devices to the pen tip assembly, so that the stylus can switch the matching signal matched with different electronic devices, one stylus can be applied to electronic devices with different matching signals, and the application range and practicability of the stylus are improved.

[0129] In order to make the above-mentioned purposes, features and advantages of the embodiments of the application more obvious and easy to understand, the technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, not all the embodiments. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the application.

And the processor can also control the touch screen 21 to display the writing track of the stylus 1 according to the matching signal sent by the stylus 1. Thus, the stylus 1 can be used to operate the touch screen 21, and the use convenience of the electronic device 2 is improved.

[0131] The stylus 1 can be applied to the touch screen 21 with different matching signals, so that one stylus 1 can be used in electronic devices 2 with different matching signals.

[0132] Reference Figure 2 The embodiments of the application also provide a stylus 1, which can include a pen tip assembly 100, a pen barrel 200, a control assembly 300, a first switch 400 and a second switch 500.

In addition to enabling the electronic device to determine the writing trajectory by sending the matching signal to the electronic device, the pen tip assembly 100 is also configured to enable the electronic device to correct the position of the pen tip assembly 100 in contact with the touch screen by sending the matching signal to the electronic device to determine the tilt angle of the stylus 1 relative to the touch screen of the electronic device.

[0134] The pen barrel 200 has a first cavity 210, an opening of the first cavity 210 is directed towards the pen tip assembly 100, the first cavity 210 is configured to extend along the length direction of the pen barrel 200, and at least a portion of the pen tip assembly 100 is disposed in the first cavity 210 through the opening and connected with the pen barrel 200. The pen tip assembly 100 is configured to rotate relative to the pen barrel 200 around a first axis (e.g. Figure 2 The pen barrel 200 and the pen tip assembly 100 can be connected through a detachable connection, so that the pen tip assembly 100 or the pen barrel 200 can be repaired or replaced individually when the pen tip assembly 100 or the pen barrel 200 is damaged.

The pen tip assembly 100 is provided with the sliding block, and the inner wall of the first cavity 210 is provided with the ring-shaped sliding rail around the first axis, and the sliding block can slide in the sliding rail, so that the pen tip assembly 100 can rotate relative to the pen barrel 200.

The control assembly 300 can be electrically connected with the pen tip assembly 100, so that the control assembly 300 can send the matching signal to the pen tip assembly 100.

[0137] The first switch 400 and the second switch 500 are electrically connected with the control assembly 300, and the first switch 400 and the second switch 500 can be spaced apart along the rotation direction of the pen tip assembly 100. The pen tip assembly 100 can trigger the first switch 400 or the second switch 500 during the rotation relative to the pen barrel 200, so that the first switch 400 or the second switch 500 sends an electrical signal to the control assembly 300 when triggered.

[0138] The pen tip assembly 100 can send a first matching signal to the pen tip assembly 100 when the control assembly 300 is triggered by rotating the first switch 400 relative to the pen barrel 200. The pen tip assembly 100 can send a second matching signal to the pen tip assembly 100 when the control assembly 300 is triggered by rotating the second switch 500. The first matching signal and the second matching signal are used to adapt to different electronic devices.

[0139] The present application provides a stylus 1 and an electronic device. The pen tip assembly 100 is electrically connected to the control assembly 300, and the pen tip assembly 100 can send a matching signal to the electronic device to determine the writing track, so as to realize the writing operation of the stylus 1 for the electronic device. The pen tip assembly 100 and the pen barrel 200 are rotationally connected, so that the pen tip assembly 100 can rotate relative to the pen barrel 200 around a first axis. The pen tip assembly 100 can trigger the first switch 400 or the second switch 500 electrically connected to the control assembly 300 by rotating. When the first switch 400 and the second switch 500 are triggered by the pen tip assembly 100, the control assembly 300 can send a first matching signal and a second matching signal adapted to different electronic devices to the pen tip assembly 100, so that the stylus 1 can switch the matching signal matched with different electronic devices, and one stylus 1 can be applied to electronic devices with different matching signals, thereby improving the application range and practicability of the stylus 1.

The circuit board assembly 310 is arranged in the first cavity 210 and electrically connected to the pen tip assembly 100, and the first switch 400 and the second switch 500 are arranged on the circuit board assembly 310. The signal processing unit 320 is arranged on the circuit board assembly 310, and the signal processing unit 320 is used to send a first matching signal and a second matching signal to the pen tip assembly 100 according to the electrical signals sent by the first switch 400 and the second switch 500.

[0141] In this way, the control assembly 300 includes the circuit board assembly 310 and the signal processing unit 320, and the circuit board assembly 310 can realize the electrical connection between the first switch 400, the second switch 500 and the signal processing unit 320, so as to facilitate the signal processing unit 320 to transmit signals to the first electrode 120 or the second electrode 140 of the pen tip assembly 100.

[0142] In some embodiments, if the pen tip assembly 100 includes the first electrode 120 and the second electrode 140, the first electrode 120 can be electrically connected to the circuit board assembly 310, and the second electrode 140 can also be electrically connected to the circuit board assembly 310.

[0143] Reference Figure 2In some embodiments, the circuit board assembly 310 can include a first circuit board 311 disposed in the second cavity 620 of the mounting structure 600, and the first circuit board 311 is configured to electrically connect the nib assembly 100, and the first switch 400 and the second switch 500 are disposed on the first circuit board 311, a second circuit board 312 electrically connected with the first circuit board 311, and the signal processing unit 320 is disposed on the second circuit board 312.

[0144] In this way, by disposing the first circuit board 311 and the second circuit board 312 electrically connected with each other, the first circuit board 311 is connected with the first switch 400 and the second switch 500, and the first circuit board 311 is electrically connected with the nib assembly 100, and the second circuit board 312 is configured to dispose the signal processing unit 320, which can facilitate the separate maintenance and replacement of the first switch 400, the second switch 500, and the nib assembly 100, and facilitate the separate maintenance and replacement of the signal processing unit 320.

[0145] In addition, the size of the first circuit board 311 can be smaller than the size of the second circuit board 312, so that the first circuit board 311 can be disposed in the second cavity 620, and the larger size of the second circuit board 312 can be configured to set more electronic devices, which facilitates the enrichment of the functions of the stylus 1.

[0146] Reference Figure 2 In some embodiments, the circuit board assembly 310 can further include a flexible circuit board 313, one end of the flexible circuit board 313 being electrically connected with the first circuit board 311, and the other end of the flexible circuit board 313 being configured to electrically connect with the second circuit board 312.

[0147] In this way, the circuit board assembly 310 includes the flexible circuit board 313, and the first circuit board 311 and the second circuit board 312 are electrically connected through the flexible circuit board 313, which can avoid the problem that the connection between the first circuit board 311 and the second circuit board 312 is easily damaged due to impact when the first circuit board 311 and the second circuit board 312 are directly and rigidly connected, thereby improving the durability of the circuit board assembly 310.

[0148] Reference Figure 3 In some embodiments, on the basis that the nib assembly 100 can rotate relative to the pen barrel 200, the nib assembly 100 can be inserted and pulled out relative to the pen barrel 200 along a first axis. Along the extension direction of the first axis, the nib assembly 100 can be in a first position or a second position relative to the pen barrel 200. Along the direction of the first axis, the first position and the second position are disposed at intervals.

[0149] When the nib assembly 100 is in the first position relative to the pen barrel 200 along the first axial direction, and the nib assembly 100 is rotated relative to the pen barrel 200, the first switch 400 and the second switch 500 are not triggered. That is, along the first axial direction, the nib assembly 100 is staggered with the first switch 400 and the second switch 500. When the nib assembly 100 is in the second position relative to the pen barrel 200 along the first axial direction, the nib assembly 100 can trigger the first switch 400 or the second switch 500 by rotating relative to the pen barrel 200.

[0150] In this way, when the stylus 1 is not used, the nib assembly 100 can be located in the first position relative to the pen barrel 200, so that the first switch 400 or the second switch 500 is not triggered by the rotation of the nib assembly 100 when the stylus 1 is not used, and the practicability of the stylus 1 is improved.

[0151] Reference Figure 4 In some embodiments, the first cavity 210 has a mounting structure 600 at one end facing the nib assembly 100. The mounting structure 600 is connected to the inner circumferential wall of the first cavity 210 by a connecting structure. The outer circumferential wall of the mounting structure 600 is spaced from the inner circumferential wall of the first cavity 210, so that an annular groove 610 is formed between the outer circumferential wall of the mounting structure 600 and the inner circumferential wall of the first cavity 210. The annular groove 610 has an opening facing the nib assembly 100, and the opening of the annular groove 610 communicates the inside and outside of the first cavity 210. The annular groove 610 is arranged around the circumference of the first axis.

[0152] The mounting structure 600 has a second cavity 620 in which at least part of the control assembly 300 is arranged. In this way, the mounting structure 600 can protect the control assembly 300, avoid interference of other components in the first cavity 210 with the control assembly 300, and avoid collision damage of other components in the first cavity 210 to the control assembly 300. The mounting structure 600 can also limit and fix the control assembly 300, so as to avoid the control assembly 300 from shaking inside the pen barrel 200.

[0153] The first switch 400 and the second switch 500 are connected to the control assembly 300 through the wall surface of the mounting structure 600. The wall surface of the mounting structure 600 has two openings in communication with the first cavity 210 and the second cavity 620, and the first switch 400 and the second switch 500 can be connected to the control assembly 300 through the openings. In this way, the first switch 400 and the second switch 500 are connected to the control assembly 300 through the wall surface of the mounting structure 600, which can improve the connection stability of the first switch 400 and the second switch 500 and the control assembly 300, avoid shaking of the first switch 400 and the second switch 500, and avoid triggering failure of the pen tip assembly 100 due to shaking of the first switch 400 or the second switch 500 when the first switch 400 or the second switch 500 is triggered.

[0154] The pen tip assembly 100 can include a trigger 110, which is located in the annular groove 610 and rotates along the extension path of the annular groove 610 and is used to trigger the first switch 400 or the second switch 500.

[0155] In this way, the pen tip assembly 100 extends into the annular groove 610 by using the trigger 110, and triggers the first switch 400 and the second switch 500 by rotating, the annular groove 610 can guide the trigger 110 to rotate circumferentially along the first axis, avoid deviation and shaking of the trigger 110 during rotation, improve the stability of the trigger 110 during rotation, and further improve the structural stability of the stylus 1.

[0156] In some embodiments, without limiting the rotation of the trigger 110 along the annular groove 610, the trigger 110 can also be connected to the inner wall of the mounting structure 600 or the first cavity 210 through a connecting structure, to avoid separation of the trigger 110 from the pen barrel 200 along the direction of the first axis during use of the stylus 1.

[0157] Reference Figure 4 and Figure 5 In some embodiments, the trigger 110 has a first protrusion 111 for pressing the first switch 400 when rotated to the first switch 400, and the first protrusion 111 can be disposed towards the first switch 400.

[0158] In this way, by disposing the first protrusion 111 on the trigger 110 towards the first switch 400, the first switch 400 can be triggered by the first protrusion 111, which can improve the accuracy and stability of the trigger 110 in triggering the first protrusion 111, and avoid triggering failure of the first switch 400.

[0159] The trigger 110 also has a second protrusion 112 for pressing the second switch 500 when rotated to the second switch 500.

[0160] In this way, by arranging the second protrusion 112 on the trigger 110 towards the second switch 500, the second switch 500 can be triggered by the second protrusion 112, the accuracy and stability of the trigger 110 triggering the second protrusion 112 can be improved, and the failure of the trigger 110 triggering the second switch 500 can be avoided.

[0161] Reference Figure 4 and Figure 5 In some embodiments, the first switch 400 can include a first button 410. The first button 410 has a first abutting portion 411 and a first contact 412, the first abutting portion 411 abuts the nib assembly 100, and the first contact 412 is arranged apart from the control assembly 300. When the nib assembly 100 is rotated to the first abutting portion 411, the first contact 412 is electrically connected to the control assembly 300 by pressing the first abutting portion 411.

[0162] In this way, by arranging the first abutting portion 411 and the first contact 412 on the first button 410, the structure of the first switch 400 can be simplified, the manufacturing cost of the first switch 400 can be reduced, and the manufacturing cost of the stylus 1 can be further reduced. When the first switch 400 is not triggered, the first contact 412 is arranged apart from the control assembly 300, which can avoid the false triggering of the first button 410 and improve the working stability of the first switch 400.

[0163] In some embodiments, if the stylus 1 has the mounting structure 600 and the nib assembly 100 has the trigger 110, the first contact 412 of the first button 410 can be located in the second cavity 620 of the mounting structure 600, and the first abutting portion 411 can be located between the mounting structure 600 and the inner wall of the first cavity 210. The trigger 110 can press the first abutting portion 411 to make the first contact 412 contact the control assembly 300, thereby realizing the electrical connection between the first switch 400 and the control assembly 300.

[0164] In some embodiments, the side of the first button 410 towards the control assembly 300 can also have a first connecting portion 721, so that the first button 410 is connected to the control assembly 300 through the first connecting portion 721, thereby improving the connection stability of the first button 410 and the control assembly 300.

[0165] The first connecting portion 721 can be located in the second cavity 620, and the first connecting portion 721 is larger than the opening on the mounting structure 600, so that the first connecting portion 721 cannot pass through the opening to separate from the mounting structure 600. Therefore, the first button 410 cannot be pulled out through the opening on the mounting structure 600, and the installation stability of the first button 410 on the mounting structure 600 is further improved.

[0166] Reference Figure 4 And Figure 5 In some embodiments, the first switch 400 can further include a first conductive part 420 and a second conductive part 430. The first conductive part 420 is arranged on the side of the first contact 412 facing the control assembly 300, and the second conductive part 430 is arranged on the side of the control assembly 300 facing the first conductive part 420. The first button 410 is electrically connected to the control assembly 300 through the first conductive part 420 and the second conductive part 430. When the first button 410 is pressed by the trigger part 110 towards the control assembly 300, the first button 410 drives the second conductive part 430 to move towards the first conductive part 420 on the control assembly 300. When the first conductive part 420 and the second conductive part 430 are in contact, an electrical connection is achieved, and a signal is sent to the control assembly 300.

[0167] The way in which the first button 410 achieves signal transmission from the first switch 400 to the control assembly 300 through the contact between the first conductive part 420 and the second conductive part 430 can simplify the structure of the first switch 400, improve the assembly efficiency between the first switch 400 and the control assembly 300, and thus improve the assembly efficiency of the stylus 1 while reducing the manufacturing cost of the stylus 1.

[0168] Reference Figure 4 And Figure 5 In some embodiments, the second switch 500 can include a second button 510. The second button 510 has a second abutting part 511 and a second contact 512. The second abutting part 511 is used to abut against the nib assembly 100, and the second contact 512 is arranged apart from the control assembly 300. When the nib assembly 100 is rotated to the second abutting part 511, the second contact 512 is electrically connected to the control assembly 300 by pressing the second abutting part 511.

[0169] In this way, by arranging the second abutting part 511 and the second contact 512 on the second button 510, the structure of the second switch 500 can be simplified, the manufacturing cost of the second switch 500 can be reduced, and thus the manufacturing cost of the stylus 1 can be reduced. When the second switch 500 is not triggered, the second contact 512 is arranged apart from the control assembly 300, which can avoid the situation of accidental triggering of the second button 510 and improve the working stability of the second switch 500.

[0170] In some embodiments, if the stylus 1 has the mounting structure 600 and the nib assembly 100 has the trigger 110, the second contact 512 of the second button 510 can be located in the second cavity 620 of the mounting structure 600, and the second abutting part 511 can be located between the mounting structure 600 and the inner wall of the first cavity 210. The trigger 110 can be pressed against the second abutting part 511 to make the second contact 512 contact the control assembly 300, so as to realize the electrical connection between the second switch 500 and the control assembly 300.

[0171] In some embodiments, the side of the second button 510 facing the control assembly 300 can also have a second connecting part 721, so that the second button 510 is connected to the control assembly 300 through the second connecting part 721, thereby improving the connection stability between the second button 510 and the control assembly 300.

[0172] The second connecting part 721 can be located in the second cavity 620, and the second connecting part 721 is larger than the opening on the mounting structure 600, so that the second connecting part 721 cannot be separated from the mounting structure 600 through the opening. Thus, the second button 510 cannot be separated from the mounting structure 600 through the opening, thereby further improving the installation stability of the second button 510 on the mounting structure 600.

[0173] Reference Figure 4 and Figure 5 In some embodiments, the second switch 500 can further include a third conductive part 520 and a fourth conductive part 530. The third conductive part 520 is arranged on the side of the second contact 512 facing the control assembly 300, and the fourth conductive part 530 is arranged on the side of the control assembly 300 facing the third conductive part 520. The second button 510 is electrically connected to the control assembly 300 through the third conductive part 520 and the fourth conductive part 530.

[0174] When the second button 510 is pressed by the trigger 110 towards the control assembly 300, the second button 510 drives the fourth conductive part 530 to move towards the third conductive part 520 on the control assembly 300. When the third conductive part 520 and the fourth conductive part 530 contact each other, an electrical connection is realized, and a signal is sent to the control assembly 300.

[0175] The way that the second button 510 realizes the signal sending from the second switch 500 to the control assembly 300 through the contact between the third conductive part 520 and the fourth conductive part 530 can simplify the structure of the second switch 500, improve the assembly efficiency between the second switch 500 and the control assembly 300, and thus improve the assembly efficiency of the stylus 1 while reducing the manufacturing cost of the stylus 1.

[0176] Reference Figure 4 and Figure 5In some embodiments, the first key 410 is a first elastic member. In some embodiments, the first elastic member can be a silica gel member with elastic deformation capability or a rubber member with elastic deformation capability.

[0177] In this way, by setting the first key 410 as a first elastic member, the first key 410 can control the disconnection and electrical connection between the first switch 400 and the control assembly 300 by elastic deformation, avoiding the first switch 400 from using additional structures to control the connection state between the first key 410 and the control assembly 300, thereby simplifying the structure of the first switch 400, and further improving the assembly efficiency of the first switch 400 and the assembly efficiency of the stylus 1.

[0178] In a specific implementation, if the first switch 400 further includes a first conductive member 420 arranged on the first contact 412 of the first key 410 and a second conductive member 430 arranged on the control assembly 300, when the trigger member 110 presses the first elastic member, the first elastic member drives the first conductive member 420 to move towards the second conductive member 430 by elastic deformation, and makes the first conductive member 420 and the second conductive member 430 electrically contact. When the trigger member 110 is separated from the first elastic member, the first elastic member drives the first conductive member 420 to move away from the second conductive member 430 by elastic restoring force, so as to disconnect the first conductive member 420 and the second conductive member 430.

[0179] The second key 510 is a second elastic member. In some embodiments, the second elastic member can be a silica gel member with elastic deformation capability or a rubber member with elastic deformation capability.

[0180] In this way, by setting the second key 510 as a second elastic member, the second key 510 can control the disconnection and electrical connection between the second switch 500 and the control assembly 300 by elastic deformation, avoiding the second switch 500 from using additional structures to control the connection state between the second key 510 and the control assembly 300, thereby simplifying the structure of the second switch 500, and further improving the assembly efficiency of the second switch 500 and the assembly efficiency of the stylus 1.

[0181] In a specific implementation, if the second switch 500 further comprises a third conductive member 520 arranged on the second contact 512 of the second button 510 and a fourth conductive member 530 arranged on the control assembly 300, when the trigger member 110 presses the second elastic member, the second elastic member drives the third conductive member 520 to move towards the fourth conductive member 530 through elastic deformation, and makes the third conductive member 520 and the fourth conductive member 530 electrically contact. When the trigger member 110 is separated from the second elastic member, the second elastic member drives the third conductive member 520 to move away from the fourth conductive member 530 through elastic restoring force, so as to disconnect the third conductive member 520 and the fourth conductive member 530.

[0182] With reference to Figure 6 And Figure 7 In some embodiments, the stylus 1 can further comprise a clamping member 700, the trigger member 110 is provided with an annular clamping groove 113 towards the surface of the mounting structure 600, and the annular clamping groove 113 is concentric with the annular groove 610. The clamping member 700 is arranged on the outer side wall of the mounting structure 600 towards the trigger member 110, and the clamping member 700 is located in the annular clamping groove 113.

[0183] In this way, by arranging the clamping member 700 in the annular clamping groove 113, when the clamping member 700 rotates with the trigger member 110, the clamping member 700 can rotate along the extension path of the annular clamping groove 113 in the annular clamping groove 113, the annular clamping groove 113 can prevent the clamping member 700 from separating from the pen barrel 200 along the direction of the first axis, and the connection stability between the trigger member 110 and the pen barrel 200 can be improved, thereby improving the connection stability between the nib assembly 100 and the pen barrel 200.

[0184] In addition, the annular clamping groove 113 can guide the clamping member 700 to rotate along the extension path of the annular clamping groove 113, so as to guide the nib assembly 100 to rotate around the first axis, thereby improving the accuracy and stability of the nib assembly 100 relative to the pen barrel 200 when rotating.

[0185] With reference to Figure 6 In some embodiments, the clamping member 700 is a clamping block 710, the clamping block 710 is arranged on the outer side surface of the mounting structure 600, and the clamping block 710 is located in the annular clamping groove 113.

[0186] In this way, by arranging the clamping member 700 as the clamping block 710, the structure of the clamping block 710 is relatively simple and easy to assemble, and the manufacturing cost is relatively low. On the basis of simplifying the structure of the clamping member 700, the manufacturing cost of the clamping member 700 can be reduced, and on the basis of improving the assembly efficiency of the stylus 1, the manufacturing cost of the stylus 1 can be reduced.

[0187] With reference to Figure 7In some embodiments, the clamping piece 700 is a third elastic piece 720, the third elastic piece 720 has a connecting portion 721 and a protruding portion 722, the connecting portion 721 is arranged on the side wall of the mounting structure 600 facing the trigger piece 110, and the protruding portion 722 is located in the annular clamping groove 113.

[0188] In this way, by arranging the clamping piece 700 as the third elastic piece 720, and connecting the third elastic piece 720 to the side wall of the mounting structure 600 through the connecting portion 721, and locating the protruding portion 722 in the annular clamping groove 113, the protruding portion 722 can be elastically deformed in the radial direction of the first axis, and the protruding portion 722 can reduce the vibration caused by the collision with the annular clamping groove 113 by elastic deformation when being extruded by the annular clamping groove 113, thereby improving the use comfort of the pen tip assembly 100 during rotation.

[0189] In addition, the protruding portion 722 of the third elastic piece 720 is in elastic contact with the wall surface of the annular clamping groove 113, which can reduce the contact friction between the clamping piece 700 and the annular clamping groove 113, and make the rotation of the pen tip assembly 100 more smooth, thereby improving the use comfort of the stylus 1.

[0190] In addition, the third elastic piece 720 can dynamically adjust the contact pressure between the protruding portion and the annular clamping groove 113 during rotation according to the force condition, thereby avoiding the jamming or loosening between the pen tip assembly 100 and the pen barrel 200 caused by excessive or insufficient pressure.

[0191] Reference Figure 7 In some embodiments, the mounting structure 600 has a mounting groove 630 on the outer side wall facing the trigger piece 110, and the connecting portion 721 of the third elastic piece 720 is arranged in the mounting groove 630, and the protruding portion 722 protrudes out of the mounting groove 630 and is located in the annular clamping groove 113.

[0192] In this way, by arranging the connecting portion 721 of the third elastic piece 720 in the mounting groove 630, the third elastic piece 720 can reduce the occupation of the space inside the first cavity 210 of the pen barrel 200 in the radial direction of the first axis, thereby helping to improve the utilization rate of the internal space of the first cavity 210.

[0193] In addition, by arranging the connecting portion 721 of the third elastic piece 720 in the mounting groove 630, the side wall of the mounting groove 630 can limit the connecting portion 721, thereby improving the mounting stability of the third elastic piece 720 on the mounting structure 600, and further improving the structural stability of the stylus 1.

[0194] Reference Figure 8In some embodiments, the pen tip assembly 100 can include a first electrode 120, one end of the first electrode 120 being electrically connected to the control assembly 300, and the first electrode 120 being rotatable relative to the control assembly 300. When the trigger 110 is rotated to trigger the first switch 400, the control assembly 300 sends a first matching signal to the first electrode 120. When the trigger 110 is rotated to trigger the second switch 500, the control assembly 300 sends a second matching signal to the first electrode 120. The first electrode 120 is configured to send the first matching signal or the second matching signal to an electronic device, and to cause the electronic device to determine a writing trajectory.

[0195] In this way, the pen tip assembly 100 can send the first matching signal or the second matching signal sent by the control assembly 300 to the electronic device, so as to cause the electronic device to determine the writing trajectory.

[0196] In some embodiments, if the stylus 1 also has the mounting structure 600 described above, the first electrode 120 can pass through the wall of the mounting structure 600 to be electrically connected to the control assembly 300, and the first electrode 120 can be rotatable relative to the control assembly 300.

[0197] Reference Figure 8 In some embodiments, the pen tip assembly 100 can further include a buffer assembly 130, one end of the buffer assembly 130 abutting the end of the first electrode 120 facing the control assembly 300, and the other end of the buffer assembly 130 abutting the control assembly 300. The buffer assembly 130 is configured to reduce the impact of the first electrode 120 transmitted to the control assembly 300.

[0198] The first electrode 120 is electrically connected to the control assembly 300 through the buffer assembly 130, and the buffer assembly 130 is in a pre-compressed state. In this way, the first electrode 120 can be kept in an electrically connected state with the control assembly 300 while ensuring that the first electrode 120 is rotatable relative to the control assembly 300, thereby avoiding the problem of disconnection between the first electrode 120 and the control assembly 300.

[0199] Reference Figure 8 In some embodiments, the buffer assembly 130 can include a first electrical connector 131, a second electrical connector 132, and a pre-compressed spring 133. One end of the first electrical connector 131 abuts the first electrode 120, the other end of the first electrical connector 131 is connected to the pre-compressed spring 133, the second electrical connector 132 is connected to the end of the pre-compressed spring 133 opposite to the first electrical connector 131, and the other end of the second electrical connector 132 passes through the mounting structure 600 and abuts the control assembly 300.

[0200] In this way, by setting the buffering assembly 130 as the first electrical connector 131, the pre-compression spring 133 and the second electrical connector 132, the first electrical connector 131 and the second electrical connector 132 can be arranged in the first axis direction, and when the nib assembly 100 is pressed towards the pen barrel 200, the first electrical connector 131 and the second electrical connector 132 can be further close to each other, so that the pre-compression spring 133 can be further compressed.

[0201] By comprising the first electrical connector 131, the second electrical connector 132 and the pre-compression spring 133, the buffering assembly 130 can simplify the structure of the buffering assembly 130, improve the assembly efficiency of the buffering assembly 130, and simplify the structure of the stylus 1 and improve the assembly efficiency of the stylus 1.

[0202] Reference Figure 8 In some embodiments, the nib assembly 100 can further comprise a second electrode 140, the second electrode 140 is arranged at the outer circumferential side of the first electrode 120, the second electrode 140 is electrically connected with the control assembly 300, and the second electrode 140 rotates together with the first electrode 120. When the trigger 110 rotates to trigger the first switch 400, the control assembly 300 sends a third matching signal to the second electrode 140. When the trigger 110 rotates to trigger the second switch 500, the control assembly 300 sends a fourth matching signal to the second electrode 140. The second electrode 140 sends the third matching signal or the fourth matching signal to the electronic device to determine the tilt angle of the stylus 1.

[0203] In some embodiments, if the nib assembly 100 further comprises the second electrode 140, when the trigger 110 triggers the first switch 400, the control assembly 300 can send the third matching signal to the second electrode 140 on the basis of sending the first matching signal to the first electrode 120. Or if the trigger 110 triggers the second switch 500, the control assembly 300 can send the fourth matching signal to the second electrode 140 on the basis of sending the second matching signal to the first electrode 120.

[0204] In this way, by setting the second electrode 140, the tilt angle of the stylus 1 can be detected at any time while ensuring that the stylus 1 can write on the electronic device, so that the electronic device can correct the feedback position according to the recognized angle, thereby improving the interaction experience of the user during use.

[0205] In some embodiments, if the nib assembly 100 has the buffering assembly 130, the second electrode 140 can also be arranged at the outer circumferential side of the buffering assembly 130, so that the second electrode 140 can protect the buffering assembly 130.

[0206] An insulating member can be arranged between the first electrode 120 and the second electrode 140 to avoid electrical connection between the first electrode 120 and the second electrode 140, and an insulating member can also be arranged between the second electrode 140 and the buffer assembly 130 to avoid electrical connection between the buffer assembly 130 and the second electrode 140.

[0207] In some embodiments, the second electrode 140 can be connected to the trigger 110. Alternatively, the second electrode 140 can be integrated with the trigger 110 to simplify the structure of the pen tip assembly 100, and thus simplify the structure of the stylus 1.

[0208] In some embodiments, if the stylus 1 can include a mounting structure 600, a part of the second electrode 140 can be arranged around the outer periphery of the mounting structure 600, and the second electrode 140 can pass through the wall of the mounting structure 600 to be electrically connected to the control assembly 300. While the second electrode 140 is electrically connected to the control assembly 300, the second electrode 140 can also rotate relative to the mounting structure and the control assembly 300 about the first axis.

[0209] In some embodiments, the pen tip assembly 100 can further include an annular conductive member (not shown in the figure), which is arranged around the outer periphery of the control assembly 300, and the second electrode 140 is arranged around the outer periphery of the annular conductive member, the second electrode 140 is in electrical contact with the annular conductive member, and the second electrode 140 can rotate about the annular conductive member to maintain electrical connection with the control assembly 300 during rotation.
