Description

Technical Field

[0001] This application relates to the field of stylus technology, specifically to a stylus and an electronic device. Background Technology

[0002] The stylus includes a cap and a tube, as well as a fixed structure and a sliding structure for relative sliding between the cap and the tube, allowing them to come into contact or separate. The fixed structure is connected to one end of the tube, the sliding structure is connected to the cap, and the sliding structure is slidably connected to the fixed structure. To ensure smooth sliding, there is a gap between the sliding structure and the fixed structure. This gap prevents the cap and tube from aligning properly when they come into contact and can cause wobbling, affecting the stylus's appearance and refinement. Utility Model Content

[0003] This application provides a stylus and an electronic device, aiming to improve the aesthetics of the stylus.

[0004] To achieve the above objectives, the embodiments of this application adopt the following technical solutions:

[0005] On one hand, this application provides a stylus, which includes a pen tube, a pen tip, a first support, a pen cap, and a second support; the first support is connected to the end of the pen tube away from the pen tip, and the first support is at least partially exposed outside the pen tube; the second support is slidably connected to the first support along the length direction of the pen tube, and the end of the second support away from the pen tube is connected to the pen cap; wherein, the first support is provided with a first limiting structure, and the second support is provided with a second limiting structure, and the first limiting structure and the second limiting structure cooperate to make the center line of the pen tube coincide with the center line of the pen cap along the length direction of the pen tube.

[0006] The stylus provided in this embodiment has a pen tip located at one end of the pen tube. A first bracket is connected to the end of the pen tube away from the pen tip, and a second bracket is slidably connected to the first bracket along the length of the pen tube. The end of the second bracket away from the pen tube is connected to the pen cap. The sliding of the second bracket and the first bracket relative to each other causes the pen cap to move closer to or away from the pen tube. A first limiting structure is disposed on the first bracket, and a second limiting structure is disposed on the second bracket. When the pen cap is in contact with the pen tube, the first and second limiting structures cooperate to ensure that the center line of the pen tube coincides with the center line of the pen cap along the length of the pen tube. This achieves precise positioning when the pen cap and pen tube are in contact, thereby improving the aesthetic refinement of the stylus.

[0007] In some embodiments, the first limiting structure includes a limiting groove located at the end of the first bracket away from the pen tube and extending along the length direction of the pen tube. The second limiting structure is located at the end of the second bracket away from the pen tube and is used to insert into the limiting groove along the length direction of the pen tube.

[0008] The second limiting structure is accommodated by the limiting groove, and the second limiting structure fits into the inner wall of the limiting groove, so as to achieve mutual cooperation between the limiting groove and the second limiting structure, and achieve precise positioning when the pen cap and pen tube are in contact, thereby improving the appearance and refinement of the stylus.

[0009] In other embodiments, the second limiting structure may include a limiting groove located at the end of the second support away from the pen tube, extending along the length of the pen tube. The first limiting structure includes a limiting block located at the end of the first support away from the pen tube, for insertion into the limiting groove along the length of the pen tube. By accommodating the limiting block in the limiting groove, and with the limiting block fitting against the inner wall of the limiting groove, the limiting groove and the limiting block can cooperate with each other, achieving precise positioning when the pen cap and pen tube are engaged, thereby improving the aesthetic refinement of the stylus.

[0010] In an embodiment where the first limiting structure includes a limiting groove, the second limiting structure includes a limiting pin and a fixing ring. The fixing ring is fixedly connected to the end of the second bracket away from the pen tube. The limiting pin is located on the side of the fixing ring closer to the pen tube and is connected to the fixing ring. The limiting pin is used to insert into the limiting groove along the length direction of the pen tube.

[0011] The limiting groove accommodates the limiting pin, and the limiting pin fits against the inner wall of the limiting groove, so that the limiting groove and the limiting pin cooperate with each other, achieving precise positioning when the pen cap and pen tube are in contact. This improves the exquisite appearance of the stylus. At the same time, the fixing ring surrounds the second bracket, increasing the contact area between the second limiting structure and the second bracket, and improving the connection strength between the second limiting structure and the second bracket.

[0012] In some embodiments, as the retaining ring gradually approaches the pen tube, the cross-section of the limiting pin perpendicular to the length of the pen tube gradually decreases. This facilitates the insertion of the end of the limiting pin near the pen tube into the limiting groove.

[0013] In some embodiments, the first bracket is provided with a slide that extends along the length of the pen tube; the first bracket includes a first stop portion and a second stop portion, the first stop portion being further away from the pen cap than the second stop portion; the second bracket is located within the slide, and the second bracket includes a third stop portion that slides between the first stop portion and the second stop portion, the third stop portion being used to contact the first stop portion or the second stop portion.

[0014] With the above configuration, as the second bracket slides closer to the pen tube relative to the first bracket, when the first and second limiting structures come into contact, the third stop part contacts the first stop part, and the pen cap contacts the pen tube. As the second bracket slides away from the pen tube relative to the first bracket, when the third stop part contacts the second stop part, the second bracket stops sliding, thus limiting the distance the pen cap slides relative to the pen tube.

[0015] In some embodiments, the slide includes a first slide and a second slide, both extending along the length of the pen tube, and are arranged opposite to each other in a direction perpendicular to the length of the pen tube; the second support includes a first slide plate and a second slide plate, the first slide plate being located within the first slide and the second slide plate being located within the second slide. The two slides and two slide plates arranged opposite to each other can improve the stability of the relative sliding of the first support and the second support.

[0016] In some embodiments, the first support includes a first sub-support and a second sub-support, both of which are connected to the pen tube. The first and second sub-supports are arranged along a length direction perpendicular to the pen tube, forming a slide rail. This facilitates the insertion of the second support within the first support.

[0017] In some embodiments, the first limiting structure is disposed on the first sub-support; or, the first limiting structure is disposed on the second sub-support; or, the first limiting structure is disposed at the connection between the first sub-support and the second sub-support.

[0018] In some embodiments, the first support also includes a decorative tube, which is sleeved on the first sub-support and the second sub-support. There will be a connection gap at the connection between the first sub-support and the second sub-support. The decorative tube can cover the connection gap between the first sub-support and the second sub-support. As the pen cap slides away from the pen tube, the connection gap is avoided from being exposed, thus improving the appearance of the stylus.

[0019] The first limiting structure is located at the end of the decorative tube away from the pen tube. Compared with placing the limiting groove on the first bracket, placing the limiting groove on the decorative tube can simplify the complexity of the first bracket and reduce the limitation on the size of the first bracket.

[0020] In some embodiments, the decorative tube comprises a stainless steel tube.

[0021] In some embodiments, the stylus further includes a functional module disposed on a portion of a first support exposed outside the pen tube. As the second and first supports slide relative to each other, the functional module has two states: exposed and covered by the pen cap. It is understood that when the functional module is covered by the pen cap, the user cannot interact with it; when the functional module is exposed, the user can interact with it.

[0022] In the above embodiments, the functional module includes at least one of a charging interface, an LED light, a microphone, and a speaker.

[0023] In an embodiment where the functional module includes a charging interface, the first bracket includes a first sub-bracket and a second sub-bracket, both of which are connected to the pen tube. The charging interface is disposed on the first sub-bracket, and the second sub-bracket has a first opening corresponding to the charging interface. The projection of the first opening on the first sub-bracket completely covers the charging interface. During installation, the charging interface can be installed on the first sub-bracket first, and then the first and second sub-brackets can be connected, facilitating the installation of the charging interface.

[0024] In the above embodiment, the first bracket further includes a decorative tube, which is sleeved on the first sub-bracket and the second sub-bracket. The decorative tube has a second opening, which is corresponding to the first opening, to expose the charging interface and facilitate the connection between the charging interface and the charger connector.

[0025] In some embodiments, a first magnet is provided on a first bracket, and a second magnet is provided on a second bracket. The side of the first magnet facing the second magnet has a first magnetic pole, and the side of the second magnet facing the first magnet has a second magnetic pole. The first magnetic pole and the second magnetic pole are the same. When the pen cap covers the charging interface, the first magnet is located on the side of the second magnet away from the pen tube. When the pen cap exposes the charging interface, the second magnet is located on the side of the first magnet away from the pen tube.

[0026] With the above configuration, in the locked state, the first force generated by the first and second magnets consistently drives the second magnet towards the pen tip, thereby causing the pen cap to always cover the charging port via the second bracket. The pen cap remains in contact with the pen tube, keeping the stylus in the locked state. In the open state, the second force generated by the first and second magnets consistently drives the second magnet away from the pen tip, thereby causing the pen cap to always separate from the pen tube via the second bracket, exposing the charging port, keeping the stylus in the open state.

[0027] When the pen is in the locked position, the user applies external force to pull out the cap. This force is opposite to the direction of the first force but the same as the direction of the second force. The user can feel the change in force as they pull out the cap. Similarly, when the pen is in the open position, the user can also feel the change in force when they apply external force to lock the cap.

[0028] In some embodiments, a third magnet is provided on the first bracket and a Hall element is provided on the second bracket; or, a Hall element is provided on the first bracket and a third magnet is provided on the second bracket; wherein, the Hall element and the third magnet are arranged correspondingly; and the distance between the Hall element and the third magnet is minimized when the pen cap covers the charging interface.

[0029] With the above settings, when the stylus is in the closed state, the distance between the Hall element and the third magnet is at its minimum, and the magnetic field strength detected by the Hall element is the first magnetic field strength. As the stylus slides, the distance between the third magnet and the Hall element gradually increases, and the magnetic field strength detected by the Hall element gradually decreases. When the stylus is in the open state, the magnetic field strength detected by the Hall element is the second magnetic field strength. It can be understood that the second magnetic field strength is less than the first magnetic field strength.

[0030] On the other hand, this application also provides an electronic device, which includes a touch panel and the aforementioned stylus, wherein the stylus is used to operate on the touch panel. It is understood that the beneficial effects achievable by the electronic device can be referred to the beneficial effects of the stylus described above, and will not be repeated here.

[0050] It should be noted that, in the description of the embodiments of this application, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection or an integral connection; they can also refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.

[0051] Reference Figure 1 This application provides an electronic device 300, which includes a terminal device 200 and a stylus 100. The terminal device 200 is equipped with a touch panel 201, and the stylus 100 is used to operate on the touch panel 201. The terminal device 200 may include a tablet computer, a laptop computer, a desktop computer, etc. The touch panel 201 may include a capacitive touch screen, a resistive touch screen, etc. Correspondingly, the stylus 100 may include a capacitive stylus, a resistive stylus, etc. The stylus 100 can slide or tap on the touch panel 201 of the electronic device 300, and can serve as an input device for the terminal device 200.

[0052] The stylus 100 provided in this application embodiment includes a pen tip 10, a pen tube 20 and a pen cap 30, wherein the pen tip 10 is disposed at one end of the pen tube 20 and the pen cap 30 is disposed at the other end of the pen tube 20.

[0053] Reference Figure 2 , Figure 1 The pen barrel 20 and pen cap 30 of the stylus 100 are in contact with each other. Figure 2The stylus 100 has a separate tube 20 and cap 30. The stylus 100 also includes a first support 40, which is connected to the end of the tube 20 furthest from the tip 10, and extends along the length of the tube 20. In one embodiment, the first support 40 may be completely exposed outside the tube 20; that is, one end of the first support 40 is connected to the end of the tube 20 furthest from the tip 10. In another embodiment, the first support 40 is partially located inside and partially outside the tube 20. Compared to the previous embodiment, this embodiment reduces the overall length of the stylus 100 and improves the integration of the stylus 100 structure.

[0054] The stylus 100 also includes a second support 50, which is slidably connected to the first support 40 along the length of the pen tube 20. The end of the second support 50 away from the pen tube 20 is connected to the pen cap.

[0055] Reference Figure 2 and Figure 3 , Figure 3 The connection between the first bracket 40 and the pen tube 20, and the connection between the second bracket 50 and the pen cap 30 are shown. The end of the first bracket 40 connected to the pen tube 20 can be fixed to the inner wall of the pen tube 20 by adhesive. Similarly, the end of the second bracket 50 connected to the pen cap 30 can also be fixed to the inner wall of the pen cap 30 by adhesive.

[0056] exist Figure 2 and Figure 3 In this embodiment, the second support 50 is inserted within the first support 40. It is understood that in other embodiments, the first support 40 may also be inserted within the second support 50.

[0057] In some embodiments, continue to refer to Figure 3 The stylus 100 also includes a first limiting structure 60 and a second limiting structure 70. The first limiting structure 60 is disposed on the first support 40, and the second limiting structure 70 is disposed on the second support 50. The first limiting structure 60 and the second limiting structure 70 are configured in cooperation. For example, when the stylus 100 is in the locked state, the pen tube 20 is in contact with the pen cap 30. The first limiting structure 60 and the second limiting structure 70 cooperate with each other so that the center line of the pen tube 20 coincides with the center line of the pen cap 30 in the length direction of the pen tube 20.

[0058] In some embodiments, refer to Figure 1 Both the pen tube 20 and the pen cap 30 are cylindrical. The center line of the pen tube 20 coincides with the center line of the pen cap 30, so that the outer surface of the pen tube 20 and the outer surface of the pen cap 30 are on the same cylindrical surface. This achieves precise positioning when the pen cap 30 and the pen tube 20 are in contact, thereby improving the appearance and refinement of the stylus 100.

[0059] In another embodiment, reference is made to Figure 3 and Figure 4 , Figure 4 This is a schematic diagram of the structure of a stylus with edges. The pen tube 20 has multiple first edges 21 arranged around the center line of the pen tube 20, and the pen cap 30 has multiple second edges 31 arranged around the center line of the pen cap 30. The number of first edges 21 is the same as the number of second edges 31. After the first limiting structure 60 and the second limiting structure 70 cooperate with each other, each first edge 21 and a second edge 31 are located on the same straight line, which also realizes the precise positioning when the pen cap 30 and the pen tube 20 are in contact, thereby improving the appearance and refinement of the stylus 100.

[0060] In embodiments where the first support 40 and the second support 50 slide relative to each other, to ensure smooth sliding of the pen cap 30 relative to the pen tube 20, a first gap exists between the first support 40 and the second support 50 in the extension direction perpendicular to the pen tube 20 (i.e., the Z direction). When the first limiting structure 60 and the second limiting structure 70 are engaged, a second gap exists between them. To achieve precise positioning when the pen cap 30 and the pen tube 20 are engaged, the second gap is smaller than the first gap. In some embodiments, the second gap is zero.

[0061] In some embodiments, refer to Figure 3 The first limiting structure 60 is located at the end of the first bracket 40 away from the pen tube 20, and the second limiting structure 70 is located at the end of the second bracket 50 inside the pen cap 30. For example, the second limiting structure 70 can be directly formed at the end of the second bracket 50 away from the pen tube 20, or it can be fixed to that end of the second bracket 50 away from the pen tube 20. During assembly, the second limiting structure 70 can be fixed to the end of the second bracket 50 away from the pen tube 20 first, and then the end of the second bracket 50 away from the pen tube 20 can be fixed to the inner wall of the pen cap 30.

[0062] In the above embodiment, the first limiting structure 60 includes a limiting groove 61, which is located at the end of the first support 40 away from the pen tube 20. The limiting groove 61 extends along the length of the pen tube 20, and its opening faces away from the pen tube 20. The limiting groove 61 is used to accommodate a second limiting structure 70, which can slide with the second support 50 relative to the first support 40 and be inserted into the limiting groove 61 along the length of the pen tube 20. A second gap exists between the second limiting structure 70 and the inner wall of the limiting groove 61. By accommodating the second limiting structure 70 in the limiting groove 61 and fitting the inner wall of the limiting groove 61, the limiting groove 61 and the second limiting structure 70 cooperate with each other, achieving precise positioning when the pen cap 30 and the pen tube 20 are engaged, thereby improving the appearance and refinement of the stylus 100.

[0063] In other embodiments, the second limiting structure includes a limiting groove located at the end of the second bracket away from the pen tube. The limiting groove also extends along the length of the pen tube, but its opening faces the pen tube. The limiting groove accommodates the first limiting structure, which includes a limiting block inserted into the limiting groove along the length of the pen tube. By accommodating the limiting block in the limiting groove, and ensuring the limiting block fits against the inner wall of the limiting groove, the limiting groove and the limiting block can cooperate effectively. This also allows for precise positioning when the pen cap and pen tube are engaged, thereby improving the aesthetic appearance of the stylus.

[0064] In an embodiment where the first limiting structure 60 includes a limiting groove 61, the second limiting structure 70 includes a limiting pin 71 and a retaining ring 72. The retaining ring 72 is fixedly connected to the end of the second bracket 50 away from the pen tube 20. The limiting pin 71 is located on the side of the retaining ring 72 closer to the pen tube 20 and is connected to the retaining ring 72. The limiting groove 61 is used to accommodate the limiting pin 71. The limiting pin 71 can slide with the second bracket 50 relative to the first bracket 40 and is inserted into the limiting groove 61 along the length direction of the pen tube 20. A second gap exists between the limiting pin 71 and the inner wall of the limiting groove 61. The limiting groove 61 accommodates the limiting pin 71, and the limiting pin 71 fits against the inner wall of the limiting groove 61, so that the limiting groove 61 and the limiting pin 71 cooperate with each other, achieving precise positioning when the pen cap 30 and the pen tube 20 are engaged. This improves the appearance of the stylus 100. At the same time, the fixing ring 72 surrounds the second bracket 50, increasing the contact area between the second limiting structure 70 and the second bracket 50, and improving the connection strength between the second limiting structure 70 and the second bracket 50.

[0065] In some embodiments, as the retaining ring 72 gradually approaches the pen tube 20, the cross-section of the limiting pin 71, perpendicular to the length direction of the pen tube 20, gradually decreases; this facilitates the insertion of the end of the limiting pin 71 near the pen tube 20 into the limiting groove 61. Exemplarily, the limiting pin 71 has a first outer wall 711 and a second outer wall 712. The first outer wall 711 connects the end of the limiting pin 71 near the pen tube 20 and the end connecting the retaining ring 72, and the second outer wall 712 similarly connects the end of the limiting pin 71 near the pen tube 20 and the end connecting the retaining ring 72. The distance between the first outer wall 711 and the second outer wall 712 gradually decreases as the pin approaches the pen tube 20. The planes of both the first outer wall 711 and the second outer wall 712 are parallel to the Y-direction.

[0066] In the above embodiments, the shape of the limiting groove 61 corresponds to and complements the shape of the limiting pin 71. In some embodiments, the limiting groove 61 has a bottom wall 611, a first inner wall 612, and a second inner wall 613, wherein the planes of the first inner wall 612 and the second inner wall 613 are both parallel to the Y direction. The first inner wall 612 and the second inner wall 613 are located on the side of the bottom wall 611 away from the pen tube 20, and each of the first inner wall 612 and the second inner wall 613 has one end connected to the bottom wall 611. The distance between the first inner wall 612 and the second inner wall 613 gradually increases in the direction gradually away from the pen tube 20. The first inner wall 612 fits against the first outer wall 711, and the second inner wall 613 fits against the second outer wall 712. This increases the contact area between the limiting groove 61 and the limiting pin 71, and improves the stability of the engagement between the first limiting structure 60 and the second limiting structure 70. For example, the angle formed by the plane of the first outer wall 711 and the length direction of the pen tube 20 is the same as the angle formed by the plane of the first inner wall 612 and the length direction of the pen tube 20.

[0067] In some embodiments, refer to Figure 5 The first support 40 includes a first sub-support 44 and a second sub-support 45. Both the first sub-support 44 and the second sub-support 45 extend along the length of the pen tube 20. Both the first sub-support 44 and the second sub-support 45 are connected to the pen tube 20. The end of the first sub-support 44 connected to the pen tube 20 can be fixed to the inner wall of the pen tube 20 by adhesive bonding. The end of the second sub-support 45 connected to the pen tube 20 can also be fixed to the inner wall of the pen tube 20 by adhesive bonding.

[0068] The first sub-support 44 and the second sub-support 45 are arranged along the length direction perpendicular to the pen tube 20, forming a slide 41, which facilitates the insertion of the second support 50 into the first support 40.

[0069] In the above embodiments, the first limiting structure can be disposed on the first sub-support 44; or on the second sub-support 45; or at the connection between the first sub-support 44 and the second sub-support 45. That is, in embodiments where the first limiting structure is a limiting groove, the limiting groove can be formed on the first sub-support 44, or on the second sub-support 45, or the first sub-support 44 and the second sub-support 45 can be enclosed to form the limiting groove. In this embodiment, the first sub-support 44 and the second sub-support 45 can be connected by screws, adhesive bonding, or other methods; this embodiment does not impose any limitations on this.

[0070] In the above embodiment, the first sub-support 44 and the second sub-support 45 of the first support 40 enclose a slide 41, which includes a first slide 411 and a second slide 412. Both the first slide 411 and the second slide 412 extend along the length of the pen tube 20 and are arranged opposite to each other in a direction perpendicular to the length of the pen tube 20. The second support 50 includes a first slide plate 52 and a second slide plate 53, which are also arranged opposite to each other in a direction perpendicular to the length of the pen tube 20. The first slide plate 52 is located within the first slide 411, and the second slide plate 53 is located within the second slide 412. The two slides 41 and the two slide plates arranged opposite to each other can improve the stability of the relative sliding of the first support 40 and the second support 50.

[0071] The second support 50 is located inside the slide 41, which extends along the length of the pen tube 20. In the Z direction, there is a first gap between the second support 50 and the slide 41. That is, in the Z direction, there is a first gap between the first slide plate 52 and the first slide 411, and there is also a first gap between the second slide plate 53 and the second slide 412.

[0072] In the above embodiments, the second bracket 50 further includes a connecting portion 54, and the end of the first sliding plate 52 away from the pen tube 20 and the end of the second sliding plate 53 away from the pen tube 20 are connected through the connecting portion 54. In an embodiment where the second limiting structure 70 is disposed on the second bracket 50, the second limiting structure 70 may be disposed on the connecting portion 54. In an embodiment where the second limiting structure 70 includes a limiting pin 71 and a fixing ring 72, the fixing ring 72 is sleeved on the connecting portion 54 and fixedly connected to the connecting portion 54; the limiting pin 71 is located on the side of the fixing ring 72 closer to the pen tube 20.

[0073] In some embodiments, the first support 40 includes a first stop portion 42 and a second stop portion 43, wherein the first stop portion 42 is further away from the pen cap 30 than the second stop portion 43; for example, the first stop portion 42 and the second stop portion 43 may both be disposed on the first sub-support 44, and the first stop portion 42 and the second stop portion 43 are arranged at intervals along the extending direction of the first sub-support 44; the second stop portion 43 is closer to the pen cap 30 than the first stop portion 42.

[0074] The second support 50 includes a third stop portion 51. During the relative sliding process between the second support 50 and the first support 40, the third stop portion 51 slides between the first stop portion 42 and the second stop portion 43. The third stop portion 51 is used to contact the first stop portion 42 or the second stop portion 43. For example, the third stop portion 51 can be provided at one end of the first slide plate 52 near the pen tube 20, or it can be provided at one end of the second slide plate 53 near the pen tube 20. Alternatively, both the first slide plate 52 and the second slide plate 53 near the pen tube 20 can be provided with the third stop portion 51.

[0075] Reference Figure 6 , Figure 7 and combined Figure 3 ,in, Figure 6 and Figure 7 This is a schematic diagram of the sliding connection between the first sub-support 44 and the second support 50, viewed along the Z-direction. As the second support 50 slides towards the pen tube 20 relative to the first sub-support 44, the first limiting structure 60 and the second limiting structure 70 come into contact. When the third stop part 51 contacts the first stop part 42, the pen cap 30 contacts the pen tube 20. As the second support 50 slides away from the pen tube 20 relative to the first support 40, the third stop part 51 contacts the second stop part 43, stopping the second support 50 from sliding and limiting the distance the pen cap 30 slides relative to the pen tube 20.

[0076] In some embodiments, refer to Figure 8 The first support 40 also includes a decorative tube 46, which is sleeved on the first sub-support 44 and the second sub-support 45. A connection gap exists between the first sub-support 44 and the second sub-support 45. The decorative tube 46 can cover this gap, preventing exposure of the connection gap as the pen cap 30 slides away from the pen tube 20, thus improving the aesthetic appearance of the stylus 100. The decorative tube 46 can be made of metal or non-metal materials; for example, it can include stainless steel or plastic tubing.

[0077] In the above embodiments, reference is made to Figure 8 and Figure 9 Alternatively, the first limiting structure can be located at the end of the decorative tube 46 away from the pen tube 20; that is, the limiting groove 61 is located at the end of the decorative tube 46 away from the pen tube 20. Compared to setting the limiting groove 61 on the first bracket 40, setting the limiting groove 61 on the decorative tube 46 can simplify the complexity of the first bracket 40 and reduce the limitation on the size of the first bracket 40.

[0078] In some embodiments, the end of the decorative tube 46 away from the pen cap 30 is provided with a first positioning structure 462, and the inner wall of the pen tube 20 is provided with a corresponding second positioning structure (not shown). During the assembly process, the first positioning structure 462 and the second positioning structure are connected in cooperation. For example, the first positioning structure 462 is a positioning groove, and the second positioning structure is a positioning pin. The extension direction of the positioning groove is the same as the length direction of the pen tube 20, so as to fix the relative position of the decorative tube 46 and the pen tube 20.

[0079] In some embodiments, the stylus 100 further includes a functional module 101, which is disposed on the portion of the first support 40 exposed outside the pen tube 20. In embodiments where the first support 40 includes a first sub-support 44 and a second sub-support 45, the functional module 101 is disposed on the first sub-support 44, and the second sub-support 45 has a first opening 451, which corresponds to the functional module 101. The projection of the first opening 451 on the first sub-support 44 completely covers the functional module 101. During installation, the functional module 101 can be installed on the first sub-support 44 first, and then the first sub-support 44 and the second support 45 can be connected, facilitating the installation of the functional module 101.

[0080] Reference Figure 10 and Figure 11 , refer to Figure 10 and Figure 11 In contrast Figure 6 , Figure 10 One end of the second bracket 50 is fixed to the inner wall of the pen cap 30; relative to Figure 7 , Figure 11 One end of the second bracket 50 is fixed to the inner wall of the pen cap 30. As the second bracket 50 and the first sub-bracket 44 slide relative to each other, the functional module 101 has two states: exposed and covered by the pen cap 30.

[0081] During the process of the second support 50 relative to the first sub-support 44, when the third stop part 51 contacts the first stop part 42, the pen cap 30 covers the functional module 101. When the third stop part 51 contacts the second stop part 43, the pen cap 30 does not cover the functional module 101, thus exposing the functional module 101. It is understood that when the functional module 101 is covered by the pen cap 30, the user cannot interact with the functional module 101; when the functional module 101 is exposed, the user can interact with the functional module 101.

[0082] In the above embodiments, the functional module 101 includes at least one of a charging interface, an LED light, a microphone, and a speaker.

[0083] Continue to refer to Figure 8In an embodiment where the first bracket 40 also includes a decorative tube 46, the decorative tube 46 is provided with a second opening 461, which is correspondingly provided with the first opening 451 to expose the functional module 101. When the functional module 101 is a charging interface, it is convenient for the charging interface to be connected with the charger connector.

[0084] In some embodiments, refer to Figure 6 and Figure 7 The stylus 100 also includes a first magnet 81 and a second magnet 82. The first magnet 81 is disposed on the first bracket 40, and the second magnet 82 is disposed on the second bracket 50. The side of the first magnet 81 facing the second magnet 82 has a first magnetic pole, and the side of the second magnet 82 facing the first magnet 81 has a second magnetic pole. The first and second magnetic poles are identical, and the identical magnetic poles repel each other, generating an attractive force. For example, the first magnet 81 is disposed on the first sub-bracket 44, and in the X direction, the first magnet 81 is located between the first stop portion 42 and the second stop portion 43. The charging interface disposed on the first sub-bracket 44 and the first magnet 81 are spaced apart along the extending direction of the first sub-bracket 44.

[0085] For example, the second magnet 82 is disposed on the third stop portion 51 and slides with the second bracket 50. In an embodiment where the second bracket 50 includes a first slide plate 52 and a second slide plate 53, two second magnets 82 are provided, respectively disposed on the first slide plate 52 and the second slide plate 53, and the two second magnets 82 are arranged opposite each other in an extension direction perpendicular to the first slide plate 52 or the second slide plate 53. A mounting groove is provided on the third stop portion 51 to fix the second magnet 82 within the mounting groove.

[0086] When the stylus is in the locked state, the first magnet 81 is located on the side of the second magnet 82 away from the pen tube 20. Since the first sub-support 44 is fixed to the pen tube 20, that is, the first magnet 81 on the first sub-support 44 is fixed, the first force generated by the first magnet 81 and the second magnet 82 always drives the second magnet 82 to the left, and then drives the pen cap 30 through the second support 50 (e.g., ...). Figure 11 (As shown) It always covers the functional module 101, keeping the stylus in the locked state.

[0087] When the stylus is in the open state, the second magnet 82 is located on the side of the first magnet 81 away from the pen tube 20. Similarly, the first magnet 81 is fixed, and the second force generated by the first magnet 81 and the second magnet 82 always drives the second magnet 82 to the right, thereby driving the pen cap 30 to expose the functional module 101 through the second bracket 50, so that the stylus is kept in the open state.

[0088] In the locked state, when the user applies external force to pull out the pen cap 30, the applied force is opposite in direction to the first force but in the same direction as the second force. The user can feel the change in force as they pull out the pen cap 30. Similarly, in the unlocked state, when the user applies external force to lock the pen cap 30, the user can also feel the change in force.

[0089] In some embodiments, the stylus 100 further includes a third magnet 83 and a Hall element 84, which are respectively disposed on the first support and the second support 50, and are correspondingly disposed so that the distance between the Hall element 84 and the third magnet 83 is minimized when the stylus is in the locked state. For example, the third magnet 83 is disposed on the first support and the Hall element 84 is disposed on the second support 50; or, the third magnet is disposed on the second support and the Hall element is disposed on the first support.

[0090] In some implementations, reference continues. Figure 6 and Figure 7 A Hall element 84 is disposed on the first sub-support 44, and a third magnet 83 is disposed on the first slide plate 52. When the stylus 100 is in the engaged state, the distance between the Hall element 84 and the third magnet 83 is at its minimum, and the magnetic field strength detected by the Hall element 84 is the first magnetic field strength. As the first slide plate 52 slides relative to the first sub-support 44, the distance between the third magnet 83 and the Hall element 84 gradually increases, and the magnetic field strength detected by the Hall element 84 gradually decreases. When the stylus 100 is in the unengaged state, the magnetic field strength detected by the Hall element 84 is the second magnetic field strength, which is less than the first magnetic field strength. (Refer to...) Figure 12 The stylus 100 also includes a controller 90, and a Hall element 84 is used to connect to the controller 90. When the magnetic field strength detected by the Hall element 84 is the first magnetic field strength, the controller 90 determines that the stylus 100 is in the locked state; when the magnetic field strength detected by the Hall element 84 is the second magnetic field strength, the controller 90 determines that the stylus 100 is in the open state.

[0091] In some embodiments, combined with Figure 1 and Figure 12Based on the different states of the stylus 100 determined by the controller 90, the controller 90 can change the usage scenario of the stylus 100. For example, if the controller 90 determines that the stylus 100 is in a locked state, the stylus 100 can interact with the terminal device 200 on the touch panel 201; if the controller 90 determines that the stylus 100 is in an open state, the stylus 100 can be used as a wireless mouse as an input device for the terminal device 200. For example, the stylus 100 can be used as an air mouse. In an embodiment where the stylus 100 is used as an air mouse, the stylus 100 is equipped with a gyroscope.

[0092] Reference Figure 13 , Figure 13 This is a diagram showing the arrangement of the second and third magnets. In embodiments where the stylus 100 includes both a second magnet 82 and a third magnet 83, the second magnet 82 is located at one end of the first slide plate 52 along its length, and the third magnet 83 is located at the other end of the first slide plate 52. This increases the distance between the second magnet 82 and the third magnet 83, thereby increasing the distance between the second magnet 82 and the Hall element 84. Figure 6 or Figure 7 The distance between the two magnets is adjusted to prevent the Hall element 84 from being affected by the second magnet 82 during the sliding process of the first slide plate 52, thus ensuring the stability of the Hall element 84 in detecting the magnetic field strength.
