[0022] To make the embodiments of this application clearer, they will be described below in conjunction with the accompanying drawings. It should be understood that the content mentioned below represents only some embodiments of this application, and not all embodiments are listed exhaustively. Therefore, other embodiments that can be obtained based on the following embodiments without any inventive effort fall within the protection scope of this application.

[0023] It should be understood that the terminology used herein is for the purpose of describing specific embodiments only and is not intended to impose strict limitations on the technical solutions unless the context clearly indicates otherwise. For example, the use of "a," "an," and "the" to modify a feature does not preclude the possibility that the feature may be plural in other embodiments.

[0024] It should be understood that the terms "comprising," "including," and "having" are open-ended, indicating the presence of the stated features but not excluding the possibility of other features in the embodiment. Similarly, the use of terms such as "first," "second," etc., to describe multiple features only indicates the distinction between one feature and another, and such terms do not imply order or sequence unless explicitly stated in the context.

[0025] It should be understood that, unless the context clearly indicates otherwise, the terms "setup," "connection," and "installation" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integrated connection; they can refer to a direct connection or an indirect connection via a medium. Those skilled in the art will understand the specific meaning of these terms in this document based on the specific circumstances.

[0026] In addition, for ease of description, the text will use terms of spatial relative relationship to describe the position of one feature relative to another feature, such as "inner", "outer", "end", "side", "upper", "middle", "lower", "high", "low", "axial", "circumferential", "radial", "horizontal", "vertical", "first direction", "second direction", etc. It can be understood that the spatial relative relationship between two features should include other specific situations besides those shown in the accompanying drawings of the specification.

[0027] The embodiments of this application are described below with reference to the accompanying drawings. It can be understood that the technical features involved in the different embodiments described below can be combined with each other as long as they do not conflict with each other.

[0028] Firstly, referring to Figure 1 The embodiments of this application propose a stylus tip structure, which includes a pen body assembly 10, a pen tip component 20, and a pen tip 30; the pen tip component 20 has a first cavity inside, and one end of it is connected to the pen body assembly 10, and the other end is provided with a limiting part 210, the limiting part 210 forming an opening 211, the opening 211 communicating with the first cavity; the pen tip 30 is at least partially housed inside the first cavity, and has a protrusion 321 thereon; one end of the pen tip 30 can protrude through the opening 211, and the protrusion 321 can be limited and abutted against the limiting part 210 to prevent the pen tip 30 from completely coming out of the first cavity.

[0029] In this embodiment, the pen tip component 20 is provided with a limiting part 210, and the pen tip 30 is provided with a protrusion 321. The protrusion 321 and the limiting part 210 limit and abut against each other, thereby preventing the pen tip 30 from completely coming out of the first cavity of the pen tip component 20, achieving the purpose of preventing children from accidentally swallowing the pen tip 30. The structure is reasonable and effective, and occupies little space.

[0030] It should be noted that the pen tip component 20 is detachably connected to the pen body component 10. Once the pen tip component 20 is separated from the pen body component 10, the pen tip 30 can be removed for repair and replacement.

[0031] To further explain, in this embodiment, the pen tip component 20 limits the pen tip 30, and the pen tip component 20 is detachably connected to the pen body component 10. That is to say, if the pen tip component 20 is not removed, the pen tip 30 will not fall off. Compared with the prior art in which the pen tip 30 is directly connected to the pen body component 10 by plugging or threading, it is more difficult for children to remove the pen tip component 20, thereby avoiding the risk of the pen tip 30 falling off and ensuring that children will not accidentally swallow the pen tip 30.

[0032] In some embodiments, refer to Figure 1 The protrusions 321 are distributed circumferentially along the tip 30, and the diameter of the tip 30 at the protrusions 321 is larger than the diameter of the opening 211.

[0033] In this embodiment, the protrusions 321 are continuously distributed along the circumference of the pen tip 30, and the diameter of the pen tip 30 at the protrusions 321 is larger than the diameter of the opening 211, thereby achieving the purpose of preventing the pen tip 30 from completely coming out of the first cavity of the pen tip component 20, and the limiting effect between the protrusions 321 and the limiting part 210 is more stable.

[0034] Of course, it is understandable that the protrusions 321 are distributed intermittently along the circumference of the pen tip 30, or that the protrusions 321 are only provided on one side of the circumferential surface of the pen tip 30, which can also achieve the effect of the protrusions 321 abutting against the limiting part 210, and is also a desirable implementation method.

[0035] In some embodiments, refer to Figure 1 The wall of the opening 211 can be fitted with the peripheral wall of the pen tip 30.

[0036] In this embodiment, the wall of the opening 211 can be fitted with the peripheral wall of the pen tip 30 with a clearance, thereby ensuring that when the stylus is bumped, the pen tip 30 can move along its own axis and retract into the first cavity, thus protecting the pen tip 30. At the same time, in order to prevent the pen tip 30 from shaking excessively when using the stylus, the gap between the wall of the opening 211 and the pen tip 30 should not be too large.

[0037] In some embodiments, refer to Figure 1The stylus tip structure also includes a first electrode 40, which surrounds the tip component 20 and the pen tip 30; the pen tip 30 includes a second electrode 310 and an insulating layer 320, which wraps around the second electrode 310 and isolates the first electrode 40 and the second electrode 310.

[0038] In this embodiment, the pen tip 30 includes a second electrode 310 and an insulating layer 320. The insulating layer 320 isolates the first electrode 40 and the second electrode 310, preventing direct contact and interference between the first electrode 40 and the second electrode 310. It should be noted that the first electrode 40 is a receiving antenna device used to receive signals emitted by the touchscreen device, while the second electrode 310 is an output antenna device used to emit signals to the touchscreen device.

[0039] In some embodiments, refer to Figure 1 The protrusion 321 is provided on the insulating layer 320, and the first electrode 40 has a first limiting hole 401, the wall of the first limiting hole 401 abutting against the protrusion 321.

[0040] In this embodiment, the wall of the first limiting hole 401 abuts against the protrusion 321, thereby further stabilizing the pen tip 30 and preventing the pen tip 30 from shaking during use. Of course, it is understandable that the diameter of the first limiting hole 401 is slightly larger than the diameter of the pen tip 30 at the protrusion 321; that is, a smaller gap between the wall of the opening 211 and the protrusion 321 is also a desirable implementation.

[0041] It should be understood that the interference between the wall of the first limiting hole 401 and the protrusion 321 should not be too large, that is, the clamping force between the two should not be too large, so as to ensure that when the stylus is bumped, the pen tip 30 can move and retract into the first cavity, which plays a role in protecting the pen tip 30. In other words, when the pen tip 30 moves, the wall of the first limiting hole 401 will only have a damping effect on the protrusion 321, but will not completely prevent the pen tip 30 from moving.

[0042] In some embodiments, refer to Figure 1 The pen body assembly 10 includes a pen shell 110 and a pen refill component 120, with the pen refill component 120 disposed inside the pen shell 110; the pen tip component 20 is detachably connected to the pen shell 110 and / or the first electrode 40, and the pen refill component 120 abuts against the inner wall of the first electrode 40.

[0043] In this embodiment, the pen tip component 20 is detachably connected to the pen shell 110 and / or the first electrode 40, thereby enabling the pen tip to be separated from the pen body assembly 10 for easy maintenance and replacement of the pen tip 30; in addition, the pen refill component 120 abuts against the inner wall of the first electrode 40 to support the first electrode 40.

[0044] Optionally, refer to Figure 1 The pen tip component 20 is threadedly connected to the outer wall of the first electrode 40, and the pen tip component 20 is inserted into the pen shell 110; optionally, the first electrode 40 and the pen refill component 120 can also be bonded together with an adhesive.

[0045] In some embodiments, refer to Figure 1 The pen refill component 120 is provided with a second limiting hole 121, and the hole wall of the second limiting hole 121 is in clearance fit with the peripheral wall of the pen tip 30.

[0046] In this embodiment, the wall of the second limiting hole 121 is fitted with the peripheral wall of the pen tip 30 with a clearance, thereby ensuring that when the stylus is bumped, the pen tip 30 can move along its own axis and retract into the first cavity, thus protecting the pen tip 30. At the same time, in order to prevent the pen tip 30 from wobbling too much when using the stylus, the clearance between the wall of the second limiting hole 121 and the pen tip 30 should not be too large.

[0047] In some embodiments not shown in the figures, the outer wall of the pen tip component 20 is provided with a bittering agent layer.

[0048] In this embodiment, the outer wall of the pen tip component 20 is coated with a bittering agent layer, thereby reducing the likelihood of children biting the pen tip component 20. Understandably, the bittering agent layer has a bitter taste and is non-toxic and harmless.

[0049] In some embodiments, the pen tip component 20 includes a tapered portion 220, and a limiting portion 210 is disposed at an angle to the tapered portion 220.

[0050] In this embodiment, the tapered portion 220 makes it easy for the user to hold the stylus, and the limiting portion 210 is set at an angle to the tapered portion 220. For example, the limiting portion 210 is set perpendicular to the axial direction of the pen tip 30, thereby enhancing the blocking effect on the protrusion 321 and preventing the pen tip 30 from completely leaving the first cavity.

[0051] Secondly, embodiments of this application propose a stylus that includes the stylus tip structure of the first aspect. Therefore, the stylus of the second aspect incorporates all the technical effects of the stylus tip structure of the first aspect.

[0052] It should be noted that the second aspect of the stylus also includes other structures, such as circuit boards and batteries. These other structures will not be described in detail here.

[0053] In particular, the term "and / or" in this application should be understood as follows:

[0054] In the first case, the term “and / or” between the first subject and the second subject includes any of the following meanings: (1) only the first subject; (2) only the second subject; and (3) both the first subject and the second subject.

[0055] In the second case, the term "and / or" between the last two of three or more subjects means including at least any one of the subjects. For example, "first subject, second subject and / or third subject" has the same meaning as "first subject and / or second subject and / or third subject", specifically including the following combinations: (1) only the first subject; (2) only the second subject; (3) only the third subject; (4) first subject and second subject and no third subject; (5) first subject and third subject and no second subject; (6) second subject and third subject and no first subject; and (7) first subject, second subject and third subject;

[0056] Furthermore, the character " / " in this application indicates that the objects before and after it are in an "or" relationship.

[0057] Finally, although the embodiments of this application have been described above in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the concept of this application, and such modifications and variations all fall within the scope of protection of this application.
