[0013] Optionally, the connecting segment is radially recessed relative to the main body segment to form a stepped surface at the connection between the two, the stepped surface being able to axially limit the cover portion.

[0014] Optionally, the outer diameter of the main body section matches the outer diameter of the cover section.

[0015] Optionally, the blind hole includes a constant diameter portion and a tapered portion, the tapered portion being formed at the front end of the constant diameter portion, and the outer contour of the support rod matching the inner contour of the blind hole.

[0016] Optionally, the adjustment element is made of metal, and the pen tip is made of a deformable conductive material.

[0017] A second aspect of this disclosure provides a stylus, comprising:

[0018] The pen barrel is hollow inside to form a first receiving cavity; and

[0019] A pen tip assembly is disposed in the first receiving cavity, wherein the pen tip assembly is a pen tip assembly of a stylus as described above.

[0020] The limiting member can penetrate the pen barrel and the cover section radially and then abut against the pen tip.

[0021] Optionally, the pen barrel has a radially extending threaded hole on its side wall, and the limiting member is a bolt that can be screwed into the threaded hole.

[0022] Optionally, it also includes:

[0023] A pressure sensor, disposed within the first receiving cavity, is in contact with the pen tip assembly to detect the pressure applied by the pen tip to the touchscreen; and

[0024] A control board is disposed within the first receiving cavity, and the control board is electrically connected to the pressure sensor.

[0025] The pen tip is electrically connected to the control board via the adjustment component. The control board is configured to control the current passing through the pen tip based on the pressure signal detected by the pressure sensor.

[0026] Optionally, the pressure sensor has a sensing groove recessed in the direction away from the adjusting member on the side near the adjusting member, and the end of the cover portion opposite to the pen tip has a sensing protrusion that can be embedded in the sensing groove.

Detailed Implementation

[0047] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0048] In this disclosure, unless otherwise stated, directional terms such as "inner" and "outer" refer to the outline of the corresponding component itself; directional terms such as "front," "rear," "top," and "bottom" are defined based on the usage habits of the stylus provided in this disclosure. Specifically, please refer to... Figure 1 In the diagram shown, the side pointed to by the Z-arrow is the rear and top, and vice versa for the front and bottom. Terms such as "first" and "second" used in this disclosure are for distinguishing one element from another and do not indicate sequence or importance. Furthermore, in the following description, when referring to the accompanying drawings, the same reference numerals in different drawings denote the same or similar elements.

[0049] Reference Figures 1-3 The first aspect of this disclosure provides a stylus tip assembly 10, which may include an adjustment member 2, a tip 1, and a limiting member 3. The rear end of the tip 1 may have a blind hole 11 extending toward the tip. At least the portion of the tip 1 located at the tip position is configured to be elastically deformable. It is understood that the open end surface of the blind hole is formed on the rear end surface of the tip 1, and the closed end of the blind hole 11 is formed near the tip position of the tip 1. In this disclosure, the tip position refers to the end of the stylus used for writing or touching on a touch screen. By configuring the tip position of the tip 1 to be elastically deformable, the risk of the tip 1 scratching the touch screen after long-term use is effectively avoided. (See also...) Figure 2 and Figure 3 The adjusting member 2 in this disclosure may include a sleeve portion 23 and a support rod 21. The sleeve portion 23 can be sleeved onto the outside of the pen tip 1 from the rear end, and the support rod 21 can extend from the inner end face 231 of the sleeve portion 23 into the blind hole 11. The depth of the support rod 21 extending into the blind hole 11 is adjustable, so as to adjust the axial support distance of the support rod 21 inside the pen tip 1, thereby changing the hardness of the elastically deformable part at the tip position, and thus meeting the user's creative and operational needs. Specifically, the following comparison... Figure 2 and Figure 3 Examples of how the pen tip 1 is used at different hardness levels are provided. Figure 2 The pen tip assembly 10 has three states where the support rod 21 extends into the blind hole 11 at different depths: State 1, such as... Figure 2 As shown in part a, the support rod 21 is fully inserted into the blind hole 11, and the front end of the support rod 21 can press against the bottom of the blind hole 11. At this time, the pen tip 1 has the greatest hardness. When the pen tip 1 applies pressure to the touch screen, as shown in part a, the pen tip 1 has the greatest hardness. Figure 3 As shown in part a, the pen tip 1 does not deform; state 2, as... Figure 2 As shown in part b, the front end of the support rod 21 is further away from the bottom of the blind hole 11, meaning the depth to which the support rod 21 extends into the blind hole 11 is shallower than in state 1. At this point, the pen tip 1 is softer than in state 1. When the pen tip 1 applies pressure to the touchscreen as in state 1, as... Figure 3 As shown in part b, the pen tip 1 can be slightly bent, undergoing minor deformation; state 3, as... Figure 2 As shown in section c, when the front end of the support rod 21 is further away from the bottom of the blind hole 11 compared to state 2, that is, when the depth of the support rod 21 extending into the blind hole 11 is shallower than in state 2, the pen tip 1 is softer than the pen tip 1 in state 2. When the pen tip 1 applies pressure to the touch screen as in state 1, as... Figure 3 As shown in section c, the pen tip 1 can have a more pronounced bend and undergo greater deformation. (Refer to...) Figure 1The limiting member 3 in this disclosure can be used to penetrate the cover portion 23 radially, and the limiting member 3 can be pressed against the pen tip 1 radially to press the pen tip 1 against the inner wall of the cover portion 23, thereby limiting the pen tip 1 and restricting the pen tip 1 to the target position, so as to keep the depth of the support rod 21 inserted into the blind hole 11 unchanged at the current position, and ensure that the pen tip assembly 10 always maintains the current hardness stably under long-term use and different pressure environments without shaking.

[0050] Through the above technical solution, at least a portion of the tip of the pen tip 1 is made elastically variable. By changing the depth of the support rod 21 inserted into the blind hole 11, the hardness of the pen tip 1 can be adjusted. This not only meets the diverse needs of users for the hardness of the pen tip 1, but also effectively avoids the cumbersome process of manually changing the pen tip 1 in the traditional way. Users can seamlessly switch the pen tip hardness according to the real-time writing scenario, greatly improving the smooth experience of creation and office work, and realizing the convenience and flexibility of using the stylus. In addition, by limiting the pen tip 1 and the adjustment component 2 with the limiting component 3, it can be ensured that the pen tip 1 is stable and does not wobble during use, and the hardness of the pen tip 1 can be precisely locked, ensuring that the pen tip assembly 10 always maintains a constant hardness during use, effectively avoiding changes in the hardness of the pen tip 1 due to accidental touch or pressure changes.

[0051] Reference Figures 1-3 The inner diameter of the cover portion 23 can be larger than the outer diameter of the support rod 21, so that an annular gap 22 can be formed between the cover portion 23 and the support rod 21. The pen tip 1 may include a main body segment 12 and a connecting segment 13, with the tip located at the front end of the main body segment 12. The connecting segment 13 may be located on the side of the main body segment 12 away from the tip, close to the adjusting member 2, thereby facilitating connection with the adjusting member 2. The connecting segment 13 can be inserted axially into the annular gap 22, which not only effectively improves the integration effect of the pen tip 1 and the adjusting member 2, but also effectively reduces the gap and looseness between the pen tip 1 and the adjusting member 2. The outer peripheral wall of the connecting section 13 may be provided with an external thread, and the inner peripheral wall of the cover section 23 may be formed with an internal thread corresponding to the external thread, which can be used for threaded connection with the external thread. The user can adjust the threaded area of ​​the external thread and the internal thread to achieve precise adjustment of the depth of the support rod 21 into the blind hole 11. This not only realizes the detachable connection between the adjusting part 2 and the cover section 23, but also assists the limiting part 3 in limiting the pen tip 1 and the adjusting part 2, further ensuring that the pen tip assembly 10 always maintains a constant hardness during use.

[0052] Reference Figure 1 and Figure 4A limiting hole 24 can be provided on the peripheral wall of the cover section 23. The limiting member 3 can penetrate the cover section 23 radially through the limiting hole 24, and one end of the limiting member 3 can abut against the thread groove of the external thread, thereby effectively restricting the axial movement and circumferential rotation of the cover section 23 and the connecting section 13, and ensuring the fixation of the relative position of the cover section 23 and the connecting section 13.

[0053] Reference Figure 1 and Figure 5 The connecting section 13 can be radially recessed relative to the main body section 12 to form a stepped surface at the connection between the connecting section 13 and the main body section 12. The stepped surface can axially limit the cover section 23, thereby providing a clear positioning reference for the support rod 21 to fully extend into the blind hole 11, which makes it easy for users to quickly and accurately complete the assembly and adjustment of the pen tip 1 and the adjustment component 2.

[0054] Furthermore, referring to Figure 1 The outer diameter of the main body section 12 can match the outer diameter of the cover section 23. On the one hand, this can greatly improve the assembly accuracy of the pen tip 1 and the adjustment part 2, making it easier to arrange them inside the pen barrel 4. On the other hand, when the two are arranged inside the pen barrel 4, they can be aligned with the inner wall of the pen barrel 4, which can reduce shaking during writing and provide users with a stable writing experience.

[0055] Reference Figures 1-3 The blind hole 11 may include a constant-diameter portion and a tapered portion. The tapered portion may be formed at the front end of the constant-diameter portion. The outer contour of the support rod 21 can match the inner contour of the blind hole 11, effectively ensuring the coaxiality of the blind hole 11 and the support rod 21 when adjusting the depth, thereby ensuring the adjustment accuracy of the pen tip 1's hardness. (Refer to...) Figure 1 In the embodiments provided in this disclosure, in the axial direction, the support rod 21 can extend forward from the cover portion 23, and the length of the support rod 21 can be equal to the sum of the dimensions of the connecting section 13 and the depth of the blind hole 11. In this way, when the connecting section 13 is fully inserted into the annular gap 22, the support rod 21 can be fully inserted into the blind hole 11. On the one hand, it realizes the tight fit between the components, eliminates the wobble and displacement of the pen tip 1 caused by the assembly gap, and ensures the user's writing experience. On the other hand, it reduces the wear caused by component misalignment and loosening, and improves the service life of the pen tip assembly 10.

[0056] In the embodiments provided in this disclosure, the adjusting member 2 can be made of metal to provide sufficient support for the pen tip 1 when inserted into the blind hole 11, ensuring the reliability of the pen tip 1 hardness adjustment. The pen tip 1 can be made of a deformable conductive material. When the pen tip assembly 10 provided in this disclosure is applied to the stylus mentioned below, the pen tip 1 can form a conductive sensing circuit with the touch screen through pressure sensing technology, converting different pressures applied by the pen tip 1 into changes in electrical signals, thereby realizing dynamic adjustment of the pen stroke thickness. Correspondingly, the adjusting member 2 can also be made of a conductive metal material to conduct electricity to the pen tip 1.

[0057] According to a second aspect of this disclosure, a stylus is provided, which may include a pen body 4 and a pen tip assembly 10, wherein the pen tip assembly 10 may be the pen tip assembly 10 provided in the first aspect of this disclosure, and the stylus has all the beneficial effects of the pen tip assembly 10 provided in this disclosure, which will not be elaborated here. See also... Figure 1 The pen barrel 4 can be hollow to form a first receiving cavity 41. The pen tip assembly 10 can be disposed in the first receiving cavity 41. For example, one end of the pen barrel 4 along the axial direction has an opening. The end of the pen tip assembly 10 near the adjusting member 2 can be inserted into other components in the first receiving cavity 41 through the opening, so that the pen tip 1 can protrude out of the first receiving cavity 41. While ensuring the stability of the pen tip assembly 10 and the pen barrel 4, it also facilitates the touch and writing of the pen tip assembly 10 on the touch screen. The limiting member 3 can pass through the pen barrel 4 and the cover 23 in a radial direction and then abut against the pen tip 1, thereby fixing the pen tip assembly 10 to the pen barrel 4. This effectively improves the integration effect between the components in the stylus and facilitates user operation. When the hardness of the pen tip 1 needs to be adjusted, the limiting member 3 needs to be released from its pressure on the pen tip 1 to release the connection between the pen tip 1 and the adjusting member 2. Then, the depth of the support rod 21 inserted into the blind hole 11 can be adjusted by adjusting the position of the pen tip 1.

[0058] Reference Figure 1 and Figure 6 The pen barrel 4 can be provided with a radially extending threaded hole 42. When the cover part 23 is provided with a limiting hole 24, the threaded hole 42 can be opened coaxially with the limiting hole 24 to ensure that the limiting member 3 can accurately pass through the pen barrel 4 and the cover part 23 in sequence and then abut against the pen tip 1. The limiting member 3 can be a bolt that can be screwed into the threaded hole 42, so as to realize the detachable connection between the pen barrel 4 and the pen tip assembly 10, improve the stability of the connection between the pen barrel 4 and the pen tip assembly 10, and effectively avoid the risk of the limiting member 3 falling off during the use of the stylus.

[0059] Reference Figure 7 and Figure 8The stylus may also include a pressure sensor 5, a control board 62, and a battery 61 disposed within the first receiving cavity 41. By placing the pressure sensor 5, the control board 62, and the battery 61 within the first receiving cavity 41, the overall effect between the various components of the stylus is effectively improved, and the space utilization within the first receiving cavity 41 is increased. The pressure sensor 5 can be disposed in contact with the pen tip assembly 10 to detect the pressure applied by the pen tip 1 to the touch screen. The control board 62 can be disposed within the first receiving cavity 41 and can be electrically connected to the pressure sensor 5. For example, the pressure sensor 5 can be wired to the control board 62 and can be fixed to the cavity wall of the first receiving cavity 41. The pressure sensor 5 can be directly snapped onto the cavity wall of the first receiving cavity 41 through a slot and a protrusion, or it can be plugged into the control board 62 through a plug-in structure. The control board 62 can be further connected to the pen barrel 4 through plug-in or other means. The pen tip 1 can be electrically connected to the control motherboard 62 via the adjustment component 2. The control motherboard 62 can be configured to control the current flowing through the pen tip 1 based on the pressure signal detected by the pressure sensor 5, thereby enabling the stylus to write with different line thicknesses on the touch screen and thus be suitable for different scenarios. Specifically, the following describes... Figure 2 and Figure 3 The adjustment of the thickness of the stylus strokes is explained in detail. The pen tip 1 can be made of the deformable conductive material mentioned above, and the touch screen can be a capacitive touch screen. When the user writes on the touch screen with the stylus, the pressure sensor 5 can receive the pressure signal applied to the touch screen by the pen tip 1 and convert the pressure signal into an electrical signal and transmit it to the control motherboard 62. The control motherboard 62 can control the magnitude of the current passing through the pen tip 1 according to the electrical signal. When the pen tip 1 is used for touch writing, the touch screen can accurately sense the different magnitudes of current changes passing through the pen tip 1 to adjust the thickness of the strokes.

[0060] Reference Figure 1 and Figure 11The pressure sensor 5 may have a sensing groove 51 recessed away from the adjusting member 2 on the side near the adjusting member 2. A sensing protrusion 25 embedded in the sensing groove 51 may be provided at the end of the cover portion 23 opposite to the pen tip 1. In the embodiments provided in this disclosure, the adjusting member 2 may be made of a conductive metal material, giving it a certain rigidity and conductivity. When the pen tip assembly 10 is inserted into the first receiving cavity 41, the sensing protrusion 25 can be precisely embedded in the sensing groove 51. Thus, when the user presses the screen with the pen tip 1 using the stylus, the pressure is transmitted sequentially through the pen tip 1, the adjusting member 2, and the sensing protrusion 25 and sensing groove 51 on the top of the cover portion 23 to the pressure sensor 5. In the embodiments provided in this disclosure, the pressure sensor 5 can convert pressure into an electrical signal through piezoelectric effect, piezoresistive effect, and capacitive effect, and then transmit the electrical signal to the control motherboard 62. It should be noted that when the pen tip 1 and the adjusting element 2 are made of conductive materials, the limiting element 3 can be made of a non-conductive or extremely weakly conductive material. Here, extremely weak conductivity means that the current passing through the limiting element 3 is extremely small and negligible, in order to avoid contact issues during user operation. To ensure the rigidity and limiting strength of the limiting element 3, it can be made of a non-conductive metallic material, such as a nickel-chromium alloy.

[0061] Reference Figures 7-11 The stylus may further include a battery 61, a first support 701, and a second support 702 disposed within the first receiving cavity 41. The battery 61 can supply power to the pressure sensor 5 and the control motherboard 62. In the embodiments provided in this disclosure, the battery 61 can be a rechargeable battery, enabling the stylus to provide a longer battery life after a single charge, meeting the user's continuous use needs for a period of time. In the embodiments provided in this disclosure, when the battery 61 is a rechargeable battery, a charging port (not shown in the figure) can be provided at the end of the pen 4 away from the pen tip assembly 10. This allows the stylus to continue to be used during charging, further meeting the user's continuous use needs. Figure 11 As shown, when the charging port mentioned above is located at the end away from the pen tip assembly 10, the battery 61 can also be set in the first receiving cavity 41 on the side away from the pen tip assembly 10. The control motherboard 62 can be set between the battery 61 and the pressure sensor 5. This design allows the battery 61 to be set close to the charging port, which can effectively shorten the charging line and improve the charging efficiency, while also preventing interference between the pressure sensor 5 and the control motherboard 62, thus achieving a reasonable spatial layout.

[0062] like Figure 7As shown, the first bracket 701 and the second bracket 702 can be inserted radially along the pen barrel 4, forming a slot 71 for the battery 61 and the control motherboard 62 to be inserted. In this disclosure, the cross-sections of the first bracket 701 and the second bracket 702 can be constructed as half-circular arc structures. When the first bracket 701 and the second bracket 702 are connected, they can form a bracket with a cylindrical cross-section to accommodate the battery 61 and the control motherboard 62 within the cylindrical structure, thereby achieving a detachable connection between the battery 61 and the control motherboard 62 and the pen barrel 4, facilitating the inspection and maintenance of each component. To further improve the stability of the installation of the battery 61 and the control motherboard 62, a slot 71 for the battery 61 and the control motherboard 62 to be inserted can be provided on the inner wall of the cylindrical structure, thereby effectively preventing problems such as shaking of the battery 61 and the control motherboard 62 during stylus use. (Reference) Figure 7 To ensure effective heat dissipation for the battery 61, the extension length of the second bracket 702 can be less than that of the first bracket 701. The first bracket 701, facing the second bracket 702, can have the aforementioned slot 71. When the first bracket 701 and the second bracket 702 are engaged, the battery 61 is precisely exposed on the outside of the cylindrical structure, effectively preventing overheating and improving the stability and reliability of the stylus during use. In this disclosure, the first bracket 701, facing the second bracket 702, can have a positioning post 73. The control motherboard 62 can have a positioning hole 74 corresponding to the position of the positioning post 73. Thus, when the first bracket 701 and the second bracket 702 are engaged, the positioning post 73 can pass precisely through the positioning hole 74 to limit the movement of the control motherboard 62. To improve safety during stylus use, the first bracket 701 and the second bracket 702 can be made of plastic material to ensure the stability of the components mounted on the first bracket 701 and the second bracket 702, while also providing insulation between the battery 61, the control motherboard 62, the pressure sensor 5, and the pen barrel 4.

[0063] Reference Figures 7-10The stylus may also include multiple positioning strips 72 and multiple positioning grooves 43. The multiple positioning strips 72 may protrude circumferentially at intervals on the outer wall of at least one of the first bracket 701 and the second bracket 702. In the embodiments provided in this disclosure, the multiple positioning strips 72 may be disposed on the side of the first bracket 701 away from the pen tip assembly 10. Multiple positioning grooves 43 may correspond one-to-one with the multiple positioning strips 72 and are formed circumferentially at intervals on the cavity wall of the first receiving cavity 41 for insertion and engagement with the positioning strips 72. During the insertion of the stylus into the pen barrel 4 after the first bracket 701 and the second bracket 702 have docked, the engagement of the positioning grooves 43 and the positioning strips 72 ensures that the first bracket 701 and the second bracket 702 are correctly positioned within the pen barrel 4, preventing the first bracket 701 and the second bracket 702 from shifting or rotating during insertion. Simultaneously, it increases the connection stability between the pen barrel 4 and the first bracket 701 and the second bracket 702, reducing the shaking or loosening of the first bracket 701 and the second bracket 702 within the pen barrel 4.

[0064] like Figure 6 As shown, the stylus provided in this disclosure may also include a pen cap 8, which can be fastened to one end of the pen tip assembly 10 when the stylus is not in use, to protect the pen tip 1 and improve the service life of the pen tip 1; when the user is using the stylus, the pen cap 8 can be fastened to the end of the stylus away from the pen tip assembly 10, so as to facilitate the storage of the pen cap 8.

[0065] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0066] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0067] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
