Description

Technical Field

[0001] This application relates to the field of stylus technology, and more particularly to an active stylus. Background Technology

[0002] Peripheral input components for electronic devices include passive capacitive pens and active capacitive pens. Passive capacitive pens use conductive materials at the tip to simulate a finger inputting touch commands on the touchscreen of the electronic device. Active capacitive pens output electrical signals to the touchscreen through electrodes at the tip. The touchscreen recognizes the touch commands based on the electrical signals output by the active capacitive pens. Because passive capacitive pens need to simulate a finger for touch, the pen tip is relatively thick and the accuracy is low. On the other hand, active capacitive pens do not need to simulate a finger for touch, so the pen tip is relatively thin and the accuracy is high. In scenarios where high accuracy is required, active capacitive pens have become the main peripheral input components for electronic devices.

[0003] Currently, the tip of an active capacitive pen has an angled electrode.

[0004] However, the pen tip with the partially tilted electrode is relatively large, resulting in a larger contact area between the pen tip and the touch screen. This leads to lower accuracy in detecting the touch position of the pen tip by electronic devices, and the large pen tip can also obstruct the user's view, resulting in a poor writing and drawing experience.

By setting a tilted electrode, the electronic device can detect the contact position of the first pen tip component based on the second coding signal transmitted by the tilted electrode and the first coding signal transmitted by the second pen tip component. Since contact position detection is assisted by the tilted electrode, the detection accuracy is higher and the anti-offset capability is stronger compared with contact position detection based solely on the first coding signal. Furthermore, the tilted electrode can also act as a shield, concentrating the electric field generated by the first coding signal transmitted by the second pen tip component near the touch screen, making the active pen touch more sensitive. Moreover, since the tilted electrode is located inside the pen shell, rather than partially inside the first pen tip component, compared with existing solutions, the first pen tip component does not need to accommodate the tilted electrode, thus allowing for a smaller first pen tip component, reducing the overall size of the pen tip, improving the accuracy of the touch position detected by the electronic device, and not obstructing the user's view, thereby improving the user experience.

[0040] To enable those skilled in the art to better understand the technical solutions in the embodiments of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art should fall within the protection scope of the embodiments of this application.

[0041] The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0042] It should be understood that although the terms first, second, third, etc., may be used in this application to describe various information, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of this application, first information may also be referred to as second information, and similarly, second information may also be referred to as first information.

[0043] As mentioned earlier, peripheral input components for electronic devices include passive capacitive pens and active capacitive pens. Passive capacitive pens use conductive material at the tip to simulate a finger inputting touch commands onto the touchscreen of the electronic device. Active capacitive pens output electrical signals to the touchscreen through electrodes at the tip. The touchscreen recognizes the touch commands based on these signals. Because passive capacitive pens need to simulate finger touch, their tips are relatively thick, resulting in lower accuracy. In contrast, active capacitive pens do not need to simulate finger touch, so their tips are thinner, resulting in higher accuracy. In scenarios requiring high accuracy, active capacitive pens have become the primary peripheral input component for electronic devices. Currently, active capacitive pens have a partially angled electrode covering the tip. However, this larger tip size results in a larger contact area between the tip and the touchscreen, leading to lower accuracy in detecting the touch position. Furthermore, the larger tip can obstruct the user's view, resulting in a poor writing and drawing experience.

[0044] This application provides an active pen, which includes a pen tip, a pen shell, and a tilting electrode. The pen tip includes a first pen tip assembly and a second pen tip assembly, with the second pen tip assembly partially disposed within the first pen tip assembly. The tilting electrode has a tubular structure, is disposed within the pen shell, and is sleeved outside the second pen tip assembly. By setting a tilted electrode, the electronic device can detect the contact position of the first pen tip component based on the second coding signal transmitted by the tilted electrode and the first coding signal transmitted by the second pen tip component. Since contact position detection is assisted by the tilted electrode, the detection accuracy is higher and the anti-offset capability is stronger compared with contact position detection based solely on the first coding signal. Furthermore, the tilted electrode can also act as a shield, concentrating the electric field generated by the first coding signal transmitted by the second pen tip component near the touch screen, making the active pen touch more sensitive. Moreover, since the tilted electrode is located inside the pen shell, rather than partially inside the first pen tip component, compared with existing solutions, the first pen tip component does not need to accommodate the tilted electrode, thus allowing for a smaller first pen tip component, reducing the overall size of the pen tip, improving the accuracy of the touch position detected by the electronic device, and not obstructing the user's view, thereby improving the user experience.

[0045] The active pen provided in this application is illustrated below through examples.

[0046] Figure 1 This is a cross-sectional view of an active pen provided in an embodiment of this application, such as... Figure 1 As shown, the active pen 20 includes: a pen shell 21, a pen tip 10, and a tilting electrode 22. The pen tip 10 includes a first pen tip assembly 11 and a second pen tip assembly 12. The second pen tip assembly 12 is partially disposed inside the first pen tip assembly 11. The first pen tip assembly 11 is at least partially located outside the pen shell 21, and the second pen tip assembly 12 is partially located inside the pen shell 21. The tilting electrode 22 has a tubular structure. The tilting electrode 22 is disposed inside the pen shell 21 and is sleeved outside the second pen tip assembly 12. The tilting electrode 22 is insulated from the second pen tip assembly 12.

[0047] The first pen tip assembly 11 is configured to contact the touch screen of the electronic device, the second pen tip assembly 12 is used to output a first coding signal, and the tilting electrode 22 is used to output a second coding signal, so that the electronic device can determine the contact position between the first pen tip assembly 11 and the touch screen based on at least the first coding signal and the second coding signal.

[0048] The active pen 20 includes a pen housing 21, a pen tip 10, and a tilting electrode 22. The pen tip 10 includes a first pen tip assembly 11 and a second pen tip assembly 12. The second pen tip assembly 12 is partially located inside the pen housing 21, and the first pen tip assembly 11 surrounds the end of the second pen tip assembly 12 located outside the pen housing 21. Optionally, the first pen tip assembly 11 is made of a non-conductive plastic material, such as polycarbonate (PC plastic) and ABS plastic, or nylon and glass fiber, etc., and the second pen tip assembly 12 is made of a metal material, such as stainless steel. The second pen tip assembly 12 can output a first coding signal. Optionally, the second pen tip assembly 12 can be electrically connected to a first driving unit (not shown in the figure) in the active pen 20, and the second pen tip assembly 12 can output the first coding signal under the drive of the first driving unit.

[0049] The tilting electrode 22 is located inside the pen shell 21 and sleeved on the outside of the second pen tip assembly 12. The tilting electrode 22 can output a second coding signal. Optionally, the tilting electrode 22 is electrically connected to the second driving unit (not shown in the figure) in the active pen 20. The tilting electrode 22 can output a second coding signal under the drive of the second driving unit. The first coding signal can be transmitted to the receiving electrode on the touch screen through the coupling capacitor between the second pen tip assembly 12 and the touch screen. The second coding signal can be transmitted to the receiving electrode on the touch screen through the coupling capacitor between the shielding electrode 23 and the touch screen. The electronic device can identify the contact position between the first pen tip assembly 11 and the touch screen based on the first coding signal output by the second pen tip assembly 12 and the second coding signal output by the tilting electrode 22.

[0050] The tilting electrode 22 is insulated from the second pen tip assembly 12. Optionally, the tilting electrode 22 and the second pen tip assembly 12 can be insulated with an insulating layer, that is, an insulating layer can be provided between the tilting electrode 22 and the second pen tip assembly 12. Alternatively, the tilting electrode 22 and the second pen tip assembly 12 can be insulated with air, that is, the inner surface of the tilting electrode 22 and the outer surface of the second pen tip assembly 12 do not contact each other and there is a certain gap. The specific insulation method can be set as needed.

[0051] It should be understood that, in addition to outputting the second coding signal, the tilted electrode 22 also serves a shielding function. Specifically, the second pen tip assembly 12 is partially located within the tilted electrode 22. The tilted electrode 22 can shield the portion of the second pen tip assembly 12 located within the tilted electrode 22 from generating an electric field, thus concentrating the electric field generated by the first coding signal on the second pen tip assembly 12 outside the tilted electrode 22. For example: Figure 1As shown in the structure, the second end of the second pen tip assembly 12 is located inside the pen shell 21. The second pen tip assembly 12 can receive the first coding signal through the second end. Since part of the structure of the second pen tip assembly 12 is located inside the tilted electrode 22, the electric field generated by the first coding signal is concentrated at the first end of the second pen tip assembly 12 (the end located outside the pen shell 21), which can make the active pen 20 more sensitive.

[0052] In this embodiment, the active pen 20 includes a pen tip 10, a pen housing 21, and a tilting electrode 22. The pen tip 10 includes a first pen tip assembly 11 and a second pen tip assembly 12, with the second pen tip assembly 12 partially disposed within the first pen tip assembly 11. The tilting electrode 22 has a tubular structure, is disposed within the pen housing 21, and is sleeved outside the second pen tip assembly 12. By setting the tilted electrode 22, the electronic device can detect the contact position of the first pen tip assembly 11 based on the second coding signal transmitted by the tilted electrode 22 and the first coding signal transmitted by the second pen tip assembly 12. Since the contact position detection is assisted by the tilted electrode 22, the detection accuracy is higher and the anti-offset capability is stronger compared with the contact position detection based solely on the first coding signal. Furthermore, the tilted electrode 22 can also act as a shield, concentrating the electric field generated by the first coding signal transmitted by the second pen tip assembly 12 at the end of the second pen tip assembly 12 closest to the touch screen, making the active pen 20 more sensitive to touch. Moreover, since the tilted electrode 22 is located inside the pen shell 21 and not partially inside the first pen tip assembly 11, compared with the existing solution, the first pen tip assembly 11 does not need to accommodate the tilted electrode 22, so a smaller first pen tip assembly 11 can be set, reducing the overall size of the pen tip 10, improving the accuracy of the touch position detected by the electronic device, and not obstructing the user's view, thus improving the user experience.

[0053] Figure 2 This is a cross-sectional view of a first pen tip assembly provided in an embodiment of this application, such as... Figure 2 As shown, the first pen tip assembly 11 has a receiving hole 111 at one end near the pen shell 21, and the second pen tip assembly 12 is partially located inside the receiving hole 111. The end of the first pen tip assembly 11 away from the pen shell 21 is used to contact the touch screen.

[0054] In this embodiment, a receiving hole 111 is provided at one end of the first pen tip assembly 11 near the pen shell 21. The receiving hole 111 can accommodate part of the structure of the second pen tip assembly 12, so that part of the second pen tip assembly 12 is disposed inside the first pen tip assembly 11, and the first pen tip assembly 11 covers part of the second pen tip assembly 12. Thus, when in use, the first pen tip assembly 11, which covers the second pen tip assembly 12, comes into contact with the touch screen, which can prevent the metal second pen tip assembly 12 from damaging the touch screen.

[0055] Figure 3 This is a cross-sectional view of a second pen tip assembly provided in an embodiment of this application, such as... Figure 3 As shown, the second pen tip assembly 12 includes a first sub-assembly 121 and a second sub-assembly 122. The first sub-assembly 121 is located outside the pen housing 21, and the second sub-assembly 122 is partially located inside the pen housing 21. The first sub-assembly 121 and part of the second sub-assembly 122 are located within the receiving hole 111. The projection of the first end of the first sub-assembly 121 onto the plane where the second end of the first sub-assembly 121 is located is within the edge of the second end of the first sub-assembly 121. The second end of the first sub-assembly 121 is connected to the first end of the second sub-assembly 122, and the first end of the second sub-assembly 122 is located within the edge of the second end of the first sub-assembly 121.

[0056] The second pen tip assembly 12 includes a first sub-assembly 121 and a second sub-assembly 122, which are connected. In one example, the first sub-assembly 121 and the second sub-assembly 122 can be integrally formed. The projection of the first end of the first sub-assembly 121 onto the plane containing the second end of the first sub-assembly 121 is located within the edge of the second end of the first sub-assembly 121, meaning the area of ​​the end face of the first end of the first sub-assembly 121 is smaller than the area of ​​the end face of the second end of the first sub-assembly 121. Similarly, the first end of the second sub-assembly 122 is located within the edge of the second end of the first sub-assembly 121, meaning the area of ​​the end face of the first end of the second sub-assembly 122 is smaller than the area of ​​the end face of the second end of the second sub-assembly 122.

[0057] It should be understood that, assuming the second pen tip assembly 12 is entirely a columnar structure or the pen tip 10 is a prior art solution, when the pen tip 10 contacts the cover plate of the touch screen, there are multiple coupling capacitors between different areas of the pen tip 10 and multiple electrodes on the touch screen. For example, there is a first coupling capacitor S1 between the left side of the second pen tip assembly 12 and the first electrode in the touch screen; there is a second coupling capacitor S2 between the end face of the second pen tip assembly 12 located outside the pen shell 21 and the second electrode in the touch screen; and there is a third coupling capacitor S3 between the right side of the second pen tip assembly 12 and the third electrode in the touch screen. When the active pen 20 changes from a vertical state to a tilted state, because the second pen tip assembly 12 is entirely a columnar structure, the change in some coupling capacitors is relatively large, causing the coordinates of the contact position between the first pen tip assembly 11 and the touch screen detected by the electronic device to shift.

[0058] In one example, Figure 4 This is a schematic diagram illustrating a change in coupling capacitance provided in an embodiment of this application, as shown below. Figure 4As shown, when the tilt angle of the active pen 20 changes from 90 degrees to 45 degrees, the first coupling capacitor S1 changes by 0.007 pF, and the third coupling capacitor S3 changes by -0.019 pF, which are relatively large changes. When the second pen tip assembly 12 is the solution provided in this application embodiment, that is, the second pen tip assembly 12 includes a first sub-assembly 121 and a second sub-assembly 122, the projection of the first end of the first sub-assembly 121 onto the plane where the second end of the first sub-assembly 121 is located is within the edge of the second end of the first sub-assembly 121, and the first end of the second sub-assembly 122 is located within the edge of the second end of the first sub-assembly 121, so that the portion of the second pen tip assembly 12 near the touch screen forms a structure similar to a cone or frustum, the change in coupling capacitance between the second pen tip assembly 12 and the receiving electrode can be small when the active pen 20 is tilted. Figure 5 This is a schematic diagram of another coupling capacitance change provided in an embodiment of this application, as shown below. Figure 5 As shown, under special dimensions, using the structure provided in this application embodiment, when the tilt angle of the active pen 20 changes from 90 degrees to 45 degrees, the first coupling capacitor S1 changes by 0.004pF and the third coupling capacitor S3 changes by -0.011pF, both of which are small changes. This can effectively improve the situation where the coordinates of the contact position between the first pen tip component 11 and the touch screen detected by the electronic device are offset.

[0059] Optionally, the first sub-component 121 is a hemispherical, conical, pyramidal, frustum or truncated cone structure, and the second sub-component 122 is a columnar structure.

[0060] In this embodiment, the second pen tip assembly 12 includes a first sub-assembly 121 and a second sub-assembly 122. The projection of the first end of the first sub-assembly 121 onto the plane containing the second end of the first sub-assembly 121 is located within the edge of the second end of the first sub-assembly 121. The second end of the first sub-assembly 121 is connected to the first end of the second sub-assembly 122. The first end of the second sub-assembly 122 is located within the edge of the second end of the first sub-assembly 121. Thus, the end of the second pen tip assembly 12 near the touch screen is similar to a cone or frustum shape, which can improve the situation where the coordinates of the contact position between the first pen tip assembly 11 and the touch screen detected by the electronic device shift when the active pen 20 changes its tilt angle.

[0061] In one possible implementation, such as Figure 3 As shown, when the first sub-component 121 is a frustum or truncated cone structure, the second pen tip component 12 also includes a third sub-component 123. The first end of the third sub-component 123 is a spherical surface, and the second end of the third sub-component 123 is connected to the first end of the first sub-component 121. The third sub-component 123 is located in the receiving hole 111.

[0062] Optionally, the projection of the third sub-component 123 onto the plane containing the first end of the first sub-component 121 is located within the edge of the first end of the first sub-component 121. That is, in the direction from the second end of the third sub-component 123 to the first end of the third sub-component 123, the distance between the point on the sphere and the axis of the second pen tip assembly 12 decreases linearly. In other words, the distance between the endpoint of the first end of the third sub-component 123 and the plane containing the second end of the third sub-component 123 is less than the radius of the sphere.

[0063] Optionally, the projection of the second end of the third sub-component 123 onto the plane containing the first end of the first sub-component 121 coincides with the first end of the first sub-component 121, that is, the second end of the third sub-component 123 has the same shape and size as the first end of the first sub-component 121.

[0064] In this embodiment, when the first sub-component 121 is a frustum or truncated cone structure, the second pen tip component 12 further includes a third sub-component 123. The first end of the third sub-component 123 is a spherical surface, and the second end of the third sub-component 123 is connected to the first end of the first sub-component 121. This allows the first end of the second pen tip component 12 to be a spherical surface, and the endpoint of the first end of the second pen tip component 12 to be point-coupled with the receiving electrode of the touch screen, which can achieve higher precision.

[0065] In one possible implementation, such as Figure 3 As shown, the second sub-component 122 includes a first structural member 1221, a second structural member 1222, and a third structural member 1223. The first end of the first structural member 1221 is connected to the second end of the first sub-component 121, and the second end of the first structural member 1221 is connected to the first end of the second structural member 1222. The second end of the first structural member 1221 is located within the edge of the first end of the second structural member 1222. The second end of the second structural member 1222 is connected to the first end of the third structural member 1223. The first end of the third structural member 1223 is located within the edge of the second end of the second structural member 1222. The first end of the second structural member 1222 abuts against the end of the first pen tip assembly 11 near the pen shell 21, and the second end of the second structural member 1222 abuts against the internal structure of the active pen 20.

[0066] The second sub-component 122 includes a first structural member 1221, a second structural member 1222, and a third structural member 1223. The first structural member 1221, the second structural member 1222, and the third structural member 1223 can be integrally formed. The second end of the first structural member 1221 is located within the edge of the first end of the second structural member 1222, meaning the area of ​​the end face of the second end of the first structural member 1221 is smaller than the area of ​​the end face of the first end of the second structural member 1222. Taking both as cylinders as an example, the diameter of the end face of the second end of the first structural component 1221 is smaller than the diameter of the end face of the first end of the second structural component 1222. When the second pen tip assembly 12 is connected to the first sub-pen tip assembly 10, the first structural component 1221 is located in the receiving hole 111. At this time, the size of the first end of the second structural component 1222 is larger than the size of the first end of the first structural component 1221. The part of the first end of the second structural component 1222 that is not connected to the second end of the first structural component 1221 abuts against the first pen tip assembly 11.

[0067] The second structural component 1222 and the third structural component 1223 are similar in principle. It should be understood that the active pen 20 is provided with a clamping structure. The second end of the third structural component 1223 is clamped by the clamping structure to fix the second pen tip assembly 12. The size of the second end of the second structural component 1222 is larger than the size of the first end of the third structural component 1223, so that the part of the second end of the second structural component 1222 that is not connected to the third structural component 1223 abuts against the internal structure of the active pen 20. This can prevent the third structural component 1223 from displacing towards the clamping structure under force and damaging the internal structure of the active pen 20.

[0068] Optionally, the axes of the first structural member 1221, the second structural member 1222, and the third structural member 1223 coincide.

[0069] In this embodiment, the second sub-component 122 includes a first structural member 1221, a second structural member 1222, and a third structural member 1223. The second end of the first structural member 1221 is located within the edge of the first end of the second structural member 1222. The first end of the second structural member 1222 abuts against the end of the first pen tip assembly 11 near the pen shell 21, which can prevent the first pen tip assembly 11 from being squeezed towards the pen shell 21 due to excessive force during user use. The first end of the third structural member 1223 is located within the edge of the second end of the second structural member 1222, which can make the second end of the second structural member 1222 abut against the internal structure of the active pen 20, which can prevent the second pen tip assembly 12 from moving towards the pen shell 21 due to excessive force during user use, thus preventing damage to the internal structure and improving the reliability of the active pen 20.

[0070] Figure 6 This is a cross-sectional view of another first pen tip assembly provided in an embodiment of this application, such as... Figure 6As shown, the first pen tip assembly 11 includes a fourth sub-assembly 112 and a fifth sub-assembly 113. The fourth sub-assembly 112 and the fifth sub-assembly 113 are located outside the pen shell 21. The first end of the fourth sub-assembly 112 is spherical. The second end of the fourth sub-assembly 112 is connected to the first end of the fifth sub-assembly 113. The projection of the fourth sub-assembly 112 onto the plane where the second end of the fifth sub-assembly 113 is located is within the edge of the second end of the fifth sub-assembly 113. The projection of the first end of the fifth sub-assembly 113 onto the plane where the second end of the fifth sub-assembly 113 is located is within the edge of the second end of the fifth sub-assembly 113.

[0071] Optionally, the fifth sub-component 113 can be a frustum or truncated pyramid structure.

[0072] Optionally, the projection of the fourth sub-component 112 onto the plane containing the first end of the fifth sub-component 113 is located within the edge of the first end of the fifth sub-component 113. That is, in the direction from the second end of the fourth sub-component 112 to the first end of the fourth sub-component 112, the distance between the point on the sphere and the axis of the first pen tip assembly 11 decreases linearly. In other words, the distance between the endpoint of the first end of the fourth sub-component 112 and the plane containing the second end of the fourth sub-component 112 is less than the radius of the sphere.

[0073] Optionally, the projection of the second end of the fourth sub-component 112 onto the plane containing the first end of the fifth sub-component 113 coincides with the first end of the fifth sub-component 113, that is, the second end of the fourth sub-component 112 and the first end of the fifth sub-component 113 have the same shape and size.

[0074] It should be understood that the receiving hole 111 may be provided only in the fifth sub-component 113, or the receiving hole 111 may extend through the fifth sub-component 113, and a portion of the receiving hole 111 may be located in the fourth sub-component 112. Regarding... Figure 5 The structure of the first pen tip assembly 11 shown is such that the first end of the second structural member 1222 in the second pen tip assembly 12 abuts against the second end of the fifth sub-assembly 113.

[0075] In this embodiment, the first pen tip assembly 11 includes a fourth sub-assembly 112 and a fifth sub-assembly 113. The second end of the fourth sub-assembly 112 is connected to the first end of the fifth sub-assembly 113. The projection of the fourth sub-assembly 112 onto the plane containing the second end of the fifth sub-assembly 113 is located within the edge of the second end of the fifth sub-assembly 113. The projection of the first end of the fifth sub-assembly 113 onto the plane containing the second end of the fifth sub-assembly 113 is also located within the edge of the second end of the fifth sub-assembly 113, forming an arrow-shaped pen tip 10 structure. The first end of the fourth sub-assembly 112 serves as the end of the first pen tip assembly 11 away from the pen shell 21 and contacts the touch screen. Since the first end of the fourth sub-assembly 112 is spherical, the first pen tip assembly 11 makes point contact with the touch screen, resulting in higher touch accuracy and improved user experience.

[0076] Figure 7 This is a cross-sectional view of another first pen tip assembly provided in the embodiments of this application, such as... Figure 7 As shown, the first pen tip assembly 11 also includes a sixth sub-assembly 114. The sixth sub-assembly 114 is at least partially located outside the pen shell 21. The receiving hole 111 passes through the sixth sub-assembly 114. The first end of the sixth sub-assembly 114 is connected to the second end of the fifth sub-assembly 113. The first end of the sixth sub-assembly 114 is located inside the edge of the second end of the fifth sub-assembly 113. The second end of the sixth sub-assembly 114 abuts against a portion of the structure of the second pen tip assembly 12.

[0077] The first pen tip assembly 11 also includes a sixth sub-assembly 114, which is at least partially located outside the pen housing 21. Optionally, the sixth sub-assembly 114 can be a columnar structure. The first end of the sixth sub-assembly 114 is connected to the second end of the fifth sub-assembly 113, and the second end of the sixth sub-assembly 114 abuts against a portion of the structure of the second pen tip assembly 12, for example, the second end of the sixth sub-assembly 114 abuts against the first end of the second structural member 1222. Figure 1 As shown, the pen casing 21 can be clamped to the side of the sixth sub-assembly 114. Optionally, the first structural member 1221 of the second pen tip assembly 12 is at least partially disposed within a through hole penetrating the sixth sub-assembly 114.

[0078] The first end of the sixth sub-component 114 is located inside the edge of the second end of the fifth sub-component 113, that is, the end face area of ​​the first end of the sixth sub-component 114 is smaller than the end face area of ​​the second end of the fifth sub-component 113, so that the first pen tip component 11 forms a shape similar to an arrow.

[0079] In this embodiment of the application, the first pen tip assembly 11 further includes a sixth sub-assembly 114. The sixth sub-assembly 114 is at least partially located outside the pen shell 21. The first end of the sixth sub-assembly 114 is located inside the edge of the second end of the fifth sub-assembly 113. The second end of the sixth sub-assembly 114 abuts against a portion of the structure of the second pen tip assembly 12. Since the first pen tip assembly 11 is provided with the sixth sub-assembly 114, the pen shell 21 can be clamped on the side of the sixth sub-assembly 114. This can restrict the movement of the first pen tip assembly 11 along the axis perpendicular to the pen tip 10, prevent the pen tip 10 from shaking inside the pen shell 21, improve the user experience, and prevent the pen tip 10 from bending, thus improving the reliability of the pen tip 10.

[0080] In one possible implementation, the active pen 20 further includes a shielding electrode 23, which is a tubular structure. The shielding electrode 23 is disposed inside the pen housing 21 and sleeved outside the second pen tip assembly 12. The shielding electrode 23 is insulated from the second pen tip assembly 12 and is grounded.

[0081] The active pen 20 may also include a shielding electrode 23, which is grounded and can serve as a shield. Specifically, part of the structure of the second pen tip assembly 12 is located inside the shielding electrode 23, which can concentrate the electric field generated by the first coding signal on the second pen tip assembly 12 at the first end of the second pen tip assembly 12, making the active pen 20 more sensitive.

[0082] In this embodiment, the active pen 20 further includes a shielding electrode 23, which is disposed inside the pen shell 21 and located between the second pen tip assembly 12 and the pen shell 21. The shielding electrode 23 can play a shielding role, so that the electric field generated by the transmission of the first coding signal by the second pen tip assembly 12 is concentrated at the end of the second pen tip assembly 12 near the touch screen, making the active pen 20 more sensitive to touch.

[0083] Figure 8 This is a schematic diagram of an active pen including a shielding electrode provided in an embodiment of this application. Figure 9 This is a schematic diagram of another active pen including a shielding electrode provided in an embodiment of this application. Figure 10 This is a schematic diagram of another active pen including a shielding electrode provided in the embodiments of this application. Figure 11 This is a schematic diagram of another active pen including a shielding electrode provided in an embodiment of this application. (See diagram below.) Figures 8 to 11As shown, the shielding electrode 23 is disposed between the tilting electrode 22 and the second pen tip assembly 12, and the shielding electrode 23 is insulated from the tilting electrode 22; or, the shielding electrode 23 is disposed between the tilting electrode 22 and the pen shell 21, and the shielding electrode 23 is insulated from the tilting electrode 22; or, the shielding electrode 23 and the tilting electrode 22 are respectively sleeved on different areas of the second pen tip assembly 12.

[0084] Figure 8 The diagram shows a shielding electrode 23 disposed between the tilting electrode 22 and the second pen tip assembly 12. Figure 9 The diagram shows that the shielding electrode 23 is disposed between the tilting electrode 22 and the pen shell 21. The length and shape of the shielding electrode 23 can be set as needed. Figure 10 The diagram shows the shielding electrode 23 near the second end of the second pen tip assembly 12, and the tilting electrode 22 near the first end of the second pen tip assembly 12, with the shielding electrode 23 and the tilting electrode 22 respectively fitted at different positions on the second pen tip assembly 12. Figure 11 The diagram shows a shielding electrode 23 near the first end of the second pen tip assembly 12, and a tilting electrode 22 near the second end of the second pen tip assembly 12. The shielding electrode 23 and the tilting electrode 22 are respectively fitted at different positions on the second pen tip assembly 12. Figures 8 to 11 The length and shape of the shielding electrode 23 shown can be set as needed. Optionally, for... Figure 10 and Figure 11 In this scheme, the shielding electrode 23 and the tilting electrode 22 can have some overlapping areas.

[0085] In this embodiment, the shielding electrode 23 is disposed between the tilting electrode 22 and the second pen tip assembly 12, and the shielding electrode 23 is insulated from the tilting electrode 22. Alternatively, the shielding electrode 23 is disposed between the tilting electrode 22 and the pen shell 21, and the shielding electrode 23 is insulated from the tilting electrode 22. Alternatively, the shielding electrode 23 and the tilting electrode 22 are respectively sleeved on different areas of the second pen tip assembly 12, thereby realizing the shielding electrode 23 being disposed between the pen shell 21 and the second pen tip assembly 12, so that the shielding electrode 23 can be sleeved on the outside of the second pen tip assembly 12 to provide a shielding effect on the second pen tip assembly 12.

[0086] Figure 12 This is a schematic diagram of the size of an active pen provided in an embodiment of this application, as shown below. Figure 12 As shown, in the axial direction of the second pen tip assembly 12, the minimum distance between the end of the second pen tip assembly 12 located outside the pen shell 21 and the end of the first pen tip assembly 11 away from the pen shell 21 is in the range of [0.2mm, 0.6mm].

[0087] The axial direction of the second pen tip assembly 12 is... Figure 12 The direction of the solid arrow in the middle is for Figure 12The cross-section shown has the axial direction as follows: Figure 12 In the horizontal direction, the minimum distance between the end of the second pen tip assembly 12 located outside the pen shell 21 and the end of the first pen tip assembly 11 located away from the pen shell 21 is [0.2mm, 0.6mm]. Figure 12 The length A in the figure is in the range of [0.2mm, 0.6mm], and preferably, the length A is 0.4mm.

[0088] In this embodiment, the minimum distance between the end of the second pen tip assembly 12 located outside the pen shell 21 and the end of the first pen tip assembly 11 away from the pen shell 21 in the axial direction is [0.2mm, 0.6mm]. By limiting the distance between the end of the second pen tip assembly 12 located outside the pen shell 21 and the end of the first pen tip assembly 11 away from the pen shell 21, the distance between the second pen tip assembly 12 and the touch screen when the active pen 20 touches the touch screen can be limited, thereby increasing the amount of signal received by the touch screen and improving the sensitivity of the active pen 20.

[0089] In one possible implementation, the minimum distance between the tilting electrode 22 and the endpoint of the second pen tip assembly 12 located outside the pen shell 21 in the axial direction of the second pen tip assembly 12 ranges from [2.5 mm, 6 mm].

[0090] like Figure 12 As shown, in the axial direction of the second pen tip assembly 12, that is... Figure 12 The direction indicated by the solid arrow is... Figure 12 In the horizontal direction, the minimum distance between the tilted electrode 22 and the endpoint of the second pen tip assembly 12 located outside the pen shell 21 ranges from [2.5mm, 6mm], that is... Figure 12 The length B in the middle ranges from [2.5mm, 6mm], and preferably, the length B is 0.4mm.

[0091] In this embodiment, the minimum distance between the tilted electrode 22 and the endpoint of the second pen tip assembly 12 located outside the pen shell 21 in the axial direction of the second pen tip assembly 12 is in the range of [2.5mm, 6mm]. This can limit the length of the second pen tip assembly 12 located outside the tilted electrode 22. The smaller the minimum distance between the endpoint of the second pen tip assembly 12 located outside the pen shell 21 and the tilted electrode 22, the more concentrated the electric field generated by the first coding signal on the second pen tip assembly 12 is at the end of the second pen tip assembly 12 located outside the pen shell 21, which can improve the sensitivity of the active pen 20.

[0092] In one possible implementation, the minimum distance between the plane containing the first end of the tilting electrode 22 and the plane containing the second end of the tilting electrode 22 in the axial direction of the second pen tip assembly 12 is [4mm, 10mm]. The first end of the tilting electrode 22 is close to the first pen tip assembly 11, and the second end of the tilting electrode 22 is far away from the first pen tip assembly 11.

[0093] like Figure 12 As shown, in the axial direction of the second pen tip assembly 12, that is... Figure 12 The direction indicated by the solid arrow is... Figure 12 In the horizontal direction, the minimum distance between the plane containing the first end of the tilted electrode 22 and the plane containing the second end of the tilted electrode 22 is [4mm, 10mm], that is... Figure 12 The length C in the middle is in the range of [4mm, 10mm]. Preferably, the length C is 7mm.

[0094] In this embodiment, the minimum distance between the plane where the first end of the tilted electrode 22 is located and the plane where the second end of the tilted electrode 22 is located is [4mm, 10mm]. This limits the length of the tilted electrode 22 and ensures that the tilted electrode 22 can cover most of the area of ​​the second pen tip assembly 12 located inside the pen shell 21. This concentrates the electric field generated by the first coding signal on the second pen tip assembly 12 at the end of the second pen tip assembly 12 located outside the pen shell 21, thereby improving the sensitivity of the active pen 20.

[0095] In one possible implementation, such as Figure 12 As shown, the minimum distance between the endpoint of the second pen tip assembly 12 located outside the pen shell 21 and the plane containing the second end of the first sub-assembly 121 is [0.4mm, 2mm], that is... Figure 12 The length D in the middle ranges from [0.4mm, 2mm], and preferably, the length D is 1.45mm.

[0096] In this embodiment, the minimum distance between the endpoint of the second pen tip assembly 12 located outside the pen shell 21 and the plane containing the second end of the first sub-assembly 121 is [0.4mm, 2mm]. By limiting the minimum distance between the endpoint of the second pen tip assembly 12 located outside the pen shell 21 and the plane containing the second end of the first sub-assembly 121, the situation where the coordinates of the contact position between the first pen tip assembly 11 and the touch screen detected by the electronic device are offset when the active pen 20 is tilted can be improved. In addition, the size of the second pen tip assembly 12 located outside the pen shell 21 can be limited, thereby reducing the overall size of the pen tip 10.

[0097] In one possible implementation, such as Figure 12 As shown, the spherical radius of the third sub-component 123 ranges from [0.3mm, 0.8mm], that is... Figure 12 The length of the radius R in the figure is [0.3mm, 0.8mm], preferably, the radius R is 0.36mm.

[0098] In this embodiment, the spherical radius of the third sub-component 123 is in the range of [0.3mm, 0.8mm]. By limiting the spherical radius of the third sub-component 123, the radius of the first end of the second pen tip component 12 can be limited, the size of the pen tip 10 of the active pen 20 can be reduced, the touch accuracy can be improved, and the user's view can be prevented from being obstructed during use, thereby improving the user's experience.

[0099] In one possible implementation, such as Figure 12 As shown, the minimum distance between the outer surface of the second sub-component 122 and the inner surface of the tilted electrode 22 is greater than or equal to 0.3 mm, i.e. Figure 12 The length E in the middle is greater than or equal to 0.3 mm, preferably 0.35 mm.

[0100] In this embodiment, the minimum distance between the outer surface of the second pen tip assembly 12 and the inner surface of the tilt electrode 22 is greater than or equal to 0.3 mm, which can ensure that the tilt electrode 22 and the second pen tip assembly 12 can be insulated by air, preventing the tilt electrode 22 and the second pen tip assembly 12 from being electrically connected, and ensuring the normal use of the active pen 20.

[0101] In one possible implementation, when the second end of the first sub-component 121 is circular, the diameter of the circle is greater than or equal to 0.6 mm; when the second end of the first sub-component 121 is polygonal, the distance between the center point of the polygon and any side is greater than or equal to 0.3 mm.

[0102] like Figure 12 As shown, when the first sub-component 121 is circular, Figure 12 The length E in the figure indicates the diameter of the circle when the first component is a polygon. Figure 12 The length E in the polygon indicates twice the distance between the center point of the polygon and any side. Figure 12 The length E in the middle is greater than or equal to 0.6 mm, preferably 1.21 mm.

[0103] In this embodiment, when the second end of the first sub-component 121 is circular, the diameter of the circle is greater than or equal to 0.6 mm. When the second end of the first sub-component 121 is polygonal, the distance between the center point of the polygon and any side is greater than or equal to 0.3 mm. By limiting the end face size of the second end of the first sub-component 121, the coordinates of the contact position between the first pen tip component 11 and the touch screen detected by the electronic device are offset when the active pen 20 is tilted. At the same time, the size of the pen tip 10 of the active pen 20 is reduced, which can improve the touch accuracy and prevent the user's view from being obstructed during use, thereby improving the user experience.

[0104] In one possible implementation, the distance between the surface of the first sub-component 121 and the surface of the first pen tip component 11 is greater than or equal to 0.2 mm.

[0105] The distance between the surface of the first sub-component 121 and the surface of the first pen tip assembly 11 is such that the thickness of the first pen tip assembly 11 covering the outside of the second pen tip assembly 12 is greater than or equal to 0.2 mm. Figure 12 The length F in the middle is greater than or equal to 0.2 mm, preferably 0.4 mm.

[0106] In this embodiment, the distance between the surface of the first sub-component 121 and the surface of the first pen tip component 11 is greater than or equal to 0.2 mm. By limiting the distance between the surface of the first sub-component 121 and the surface of the first pen tip component 11, the thickness of the first pen tip component 11 covering the outside of the second pen tip component 12 can be limited. While ensuring the thickness of the first pen tip component 11, the size of the pen tip 10 of the active pen 20 can be reduced, which can improve touch accuracy and prevent obstruction of the user's view during use, thereby improving the user experience.

[0107] Figure 13 This is a schematic diagram of another active pen size provided in an embodiment of this application, as shown below. Figure 13 As shown, in the axial direction of the second pen tip assembly 12, the minimum distance between the target electrode and the endpoint of the second pen tip assembly 12 located outside the pen shell 21 ranges from [2.5mm, 6mm]. The target electrode is the electrode with the smaller distance between it and the end of the second pen tip assembly 12 located outside the pen shell 21, which is either the tilting electrode 22 or the shielding electrode 23.

[0108] Figure 13 The target electrode is one of the tilted electrode 22 and the shielding electrode 23. The electrode with the smaller minimum distance from the end of the second pen tip assembly 12 located outside the pen shell 21 is the target electrode. For example, if the active pen 20 is as follows: Figure 10 The structure shown indicates that the target electrode is the tilted electrode 22, and if the active pen 20 is... Figure 11 The structure shown indicates that the target electrode is the shielding electrode 23. It should also be understood that if the active pen 20 is as follows... Figure 8 or Figure 9 The structure shown can still be applied to this scheme, that is, the target electrode is the one with a smaller distance between the tilted electrode 22 and the shielding electrode 23 and the first end of the second pen tip assembly 12. Figure 13 The direction indicated by the middle arrow is... Figure 13 In the horizontal direction, the minimum distance between the target electrode and the endpoint of the second pen tip assembly 12 located outside the pen shell 21 ranges from [2.5mm, 6mm], that is... Figure 13 The length G in the middle ranges from [2.5mm, 6mm].

[0109] In this embodiment, the minimum distance between the target electrode and the endpoint of the second pen tip assembly 12 located outside the pen shell 21 is in the range of [2.5mm, 6mm]. This can limit the length of the second pen tip assembly 12 located outside the target electrode. The smaller the minimum distance between the endpoint of the second pen tip assembly 12 located outside the pen shell 21 and the target electrode, the more concentrated the electric field generated by the first coding signal on the second pen tip assembly 12 is at the end of the second pen tip assembly 12 located outside the pen shell 21, which can improve the sensitivity of the active pen 20.
