[0034] An embodiment of the present invention provides a capacitive stylus for writing on a capacitive screen, such as Figure 1 As shown, the capacitive stylus pen includes a pen tip structure 100 and a pen body 200, and the pen tip structure 100 is mounted on the pen body 200 by bonding. Figure 2 As shown, the pen tip structure 100 includes a pen tip assembly 10 and a fixing assembly 20. The pen tip assembly 10 is conductive and is used for writing on a capacitive screen. Figure 3 and Figure 4 As shown, the fixing assembly 20 includes a supporting member 21 and a fixing member 22 . The supporting member 21 is partially inserted into the pen head assembly 10 , and the fixing member 22 is sleeved outside the pen head assembly 10 .

[0035] The above-mentioned capacitive pen, the pen head assembly 10 is used for writing on the capacitive screen. By arranging a support member 21 inside the pen head assembly 10 and arranging a fixing member 22 outside the pen head assembly 10, the pen head assembly 10 is supported and fixed from inside and outside the pen head assembly 10, thereby ensuring that the pen head assembly 10 has sufficient structural strength. In this way, the diameter of the pen head assembly 10 can be about 2mm, so that the handwriting written on the capacitive screen is more delicate. Compared with the existing 5-7mm capacitive pen, it has obvious advantages and improves the user experience.

[0036] In this embodiment, if Figure 3 and Figure 4 As shown, the support member 21 includes a base portion 211 and an insertion portion 212 connected to each other, and the pen tip assembly 10 is provided with an insertion cavity and an insertion port connected to the insertion cavity, and the insertion portion 212 is inserted into the insertion cavity through the insertion port. By providing the insertion cavity and the insertion port in the pen tip assembly 10, it is convenient to insert the insertion portion 212 of the support member 21 into the pen tip assembly 10 to complete the installation of the support member 21, so that the pen tip assembly 10 can be supported in the pen tip assembly 10. In addition, the base portion 211 of the support member 21 abuts against the pen tip assembly 10, which can provide a better support for the pen tip assembly 10. Of course, in other embodiments, the insertion cavity and the insertion port may not be provided, and the support member 21 can be directly inserted into the pen tip assembly 10.

[0037] Furthermore, in this embodiment, if Figure 4 As shown, the inner wall of the insertion port has a radial protrusion 111, and the insertion portion 212 is provided with a groove 2121 that matches the protrusion 111. During installation, the insertion portion 212 of the support member 21 can be inserted into the insertion cavity from the insertion port, and the protrusion 111 in the pen head assembly 10 and the groove 2121 outside the support member 21 are matched to achieve the positioning of the pen head assembly 10 and the support member 21, thereby ensuring the stability of the assembly of the pen head assembly 10 and the support member 21. In addition, in this embodiment, after the pen head assembly 10 and the support member 21 are assembled, the protrusion 111 does not completely press into the groove 2121, that is, there is a certain gap between the protrusion 111 and the groove 2121, so that the processing accuracy requirements of the pen head assembly 10 and the support member 21 can be reduced, and the assembly of the support member 21 is convenient. Of course, in other embodiments, the pen head assembly 10 and the support member 21 can also be fixed in other ways, such as interference fit.

[0038] Furthermore, in this embodiment, if Figure 4As shown, the end of the base part 211 away from the insertion part 212 has a radially protruding bump 2111, and the fixing member 22 abuts against the bump 2111. Since the end of the base part 211 away from the insertion part 212 has a radially protruding bump 2111 that can support the fixing member 22, the fixing member 22 can be made longer in the axial direction, so that the fixing member 22 and the support member 21 can be better matched, further ensuring that the pen head assembly 10 has sufficient structural strength, so that the diameter of the pen head assembly 10 can be made smaller, and the fineness when writing is improved. And the bump 2111 of the support member 21 abuts against the fixing member 22, so that the assembly of the entire pen head structure 100 is more compact and stable. In addition, in this embodiment, the assembly of the support member 21 and the fixing member 22 leaves a gap 30, which is convenient for assembly and reduces the difficulty of processing.

[0039] In this embodiment, the support member 21 is interference fit with the pen tip assembly 10, and the fixing member 22 is interference fit with the pen tip assembly 10. Specifically, in this embodiment, the insertion portion 212 of the support member 21 is inserted into the insertion cavity to achieve interference fit with the pen tip assembly 10, and the fixing member 22 is sleeved outside the pen tip assembly 10 and pressed against the pen tip assembly 10 to achieve interference fit with the pen tip assembly 10. In this way, the support member 21 and the fixing member 22 have a better supporting effect on the entire pen tip assembly 10, effectively improving the overall strength of the entire pen tip assembly 10, and ensuring the writing quality when the pen tip assembly 10 is thin.

[0040] In this embodiment, if Figure 4 As shown, the pen tip of the pen tip assembly 10 extends out of the fixing member 22. Since the pen tip extends out of the fixing member 22, while ensuring the fixing effect of the fixing member 20 on the pen tip assembly 10, the pen tip assembly 10 is also exposed, avoiding interference of the fixing member 20 on the pen tip, thereby facilitating the user to write on the capacitive screen and improving the user's experience.

[0041] In the present embodiment, the support member 21 is made of metal, and the fixing member 22 is a metal cylinder. Specifically, in the present embodiment, the support member 21 may be a copper needle, and the fixing member 22 may be a steel cylinder. By using metal materials to support and fix the pen head assembly 10, not only can a certain support strength be ensured, but also the pen head assembly 10 with a smaller diameter can be prevented from bending or breaking under stress, and the service life of the capacitive pen can be increased, and the production cost is also low. Of course, in other embodiments, the materials of the support member 21 and the fixing member 22 may also be other hard conductive materials.

[0042] In this embodiment, if Figure 3 and Figure 4As shown, the pen tip assembly 10 includes a pen tip body 11 and a covering member 12, the covering member 12 covers the pen tip body 11, the insertion portion 212 of the support member 21 is inserted into the insertion cavity of the pen tip body 11, and the fixing member 22 is sleeved outside the covering member 12. That is, in this embodiment, the pen tip assembly 10 adopts a double-layer structure, the internal pen tip body 11 serves as a substrate, and is covered by the covering member 12, which effectively increases the contact area with the capacitive screen, and the external covering member 12 can protect the internal pen tip body 11 on the one hand, and improve the writing experience on the other hand. In addition, in this embodiment, the covering member 12 is shaped by stamping. Of course, in other embodiments, the pen tip assembly 10 can also adopt a single-layer structure.

[0043] Furthermore, in the present embodiment, the material of the nib body 11 is a soft conductive material, and the material of the covering 12 is a soft conductive material. Specifically, in the present embodiment, the material of the nib body 11 is conductive rubber, and the material of the covering 12 is conductive cloth or conductive velvet. Since the nib body 11 and the covering 12 themselves have excellent flexibility, they can provide a good touch feedback feel when writing, further improving the user experience, and can also prevent the nib assembly 10 from being too hard and scratching the capacitive screen. Moreover, since the nib body 11 can also be conductive, the entire nib structure 100 is ensured to have excellent conductivity, making writing smoother and ensuring writing quality. Of course, in other embodiments, the material of the nib body 11 can also be other materials with similar properties to conductive rubber, and the material of the covering 12 can also be other materials that are flexible and easy to cover.

[0044] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent transformations made using the contents of the present invention's specification and drawings, or directly or indirectly applied in related technical fields, are also included in the patent protection scope of the present invention.
