An embodiment of the present invention provides a capacitive pen for writing on a capacitive screen, as shown in fig. 1, the capacitive pen includes a pen head structure 100 and a pen body 200, and the pen head structure 100 is mounted on the pen body 200 in an adhesive manner. As shown in fig. 2, the pen head structure 100 includes a pen head assembly 10 and a fixing assembly 20, the pen head assembly 10 is electrically conductive and is used for writing on a capacitive screen, as shown in fig. 3 and 4, 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.

Above-mentioned capacitance pen, written subassembly 10 is used for writing on the electric capacity screen, through set up support piece 21 in written subassembly 10, and set up mounting 22 outside written subassembly 10, support and fixed written subassembly 10 from inside and outside written subassembly 10, thereby guarantee that written subassembly 10 has sufficient structural strength, so, about 2mm can be accomplished to the diameter of written subassembly 10, make the writing of writing on the electric capacity screen more meticulous, for current 5-7 mm's capacitance pen, obvious advantage has, promote user's use and experience.

In this embodiment, as shown in fig. 3 and 4, the supporting member 21 includes a base portion 211 and an insertion portion 212 connected to each other, the nib assembly 10 is provided with an insertion cavity and an insertion opening communicating with the insertion cavity, and the insertion portion 212 is inserted into the insertion cavity through the insertion opening. The insertion cavity and the insertion opening are arranged on the pen point assembly 10, so that the insertion part 212 of the support 21 can be conveniently inserted into the pen point assembly 10 to complete the installation of the support 21, and the pen point assembly 10 can be supported in the pen point assembly 10. In addition, the base portion 211 of the supporting member 21 abuts against the pen point assembly 10, so as to provide a better supporting effect for the pen point assembly 10. Of course, in other embodiments, the insertion cavity and the insertion opening may not be provided, and the support 21 may be directly inserted into the nib assembly 10.

Further, in the present embodiment, as shown in fig. 4, the inner wall of the insertion port has a projection 111 in the radial direction, and the insertion portion 212 is provided with a groove 2121 which is fitted with the projection 111. When the pen point assembly is installed, the insertion portion 212 of the support 21 can be inserted into the insertion cavity from the insertion opening, and the protrusion 111 in the pen point assembly 10 is matched with the groove 2121 outside the support 21, so that the pen point assembly 10 and the support 21 are clamped, and the stability of assembling the pen point assembly 10 and the support 21 is ensured. In addition, in the embodiment, after the nib assembly 10 is assembled with the supporting member 21, the protrusion 111 does not completely abut into the groove 2121, i.e. a certain gap is left between the protrusion 111 and the groove 2121, so that the requirement of the processing precision of the nib assembly 10 and the supporting member 21 can be reduced, and the assembly of the supporting member 21 is facilitated. Of course, in other embodiments, the nib assembly 10 and the support 21 may be fixed by other fixing methods, such as interference fit.

Still further, in the present embodiment, as shown in fig. 4, an end of the base portion 211 away from the insertion portion 212 has a projection 2111 projecting in the radial direction, and the fixing member 22 abuts against the projection 2111. Since the end of the base portion 211, which is far from the insertion portion 212, has the protrusion 2111 which protrudes in the radial direction and 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 supporting member 21 can be better matched, and the sufficient structural strength of the nib assembly 10 can be further ensured, so that the diameter of the nib assembly 10 can be made smaller, and the fineness of writing can be improved. And the convex block 2111 of the supporting piece 21 is abutted with the fixing piece 22, so that the whole pen point structure 100 is assembled more compactly and stably. In addition, in the embodiment, the gap 30 is left between the supporting member 21 and the fixing member 22, which facilitates assembly and reduces processing difficulty.

In the present embodiment, the supporting member 21 is in interference fit with the nib assembly 10, and the fixing member 22 is in interference fit with the nib assembly 10. Specifically, in the embodiment, the insertion portion 212 of the supporting member 21 is inserted into the insertion cavity to achieve the interference fit with the pen point assembly 10, and the fixing member 22 is sleeved outside the pen point assembly 10 and abuts against the pen point assembly 10 to achieve the interference fit with the pen point assembly 10, so that the supporting function of the supporting member 21 and the fixing member 22 on the whole pen point assembly 10 is better, the overall strength of the whole pen point assembly 10 is effectively improved, and the writing quality of the pen point assembly 10 when being thinner is ensured.

In this embodiment, the nib of the nib assembly 10 extends beyond the anchor 22 as shown in FIG. 4. Because the nib stretches out outside mounting 22, when guaranteeing fixed subassembly 20 to the fixed effect of nib subassembly 10, still make nib subassembly 10 expose so, avoid fixed subassembly 20 to produce the interference to the nib to the user of being convenient for writes on the electric capacity screen, promotes user's use and experiences.

In this embodiment, the supporting member 21 is made of metal, and the fixing member 22 is a metal cylinder. Specifically, in the present embodiment, the supporting member 21 may be a copper needle, and the fixing member 22 may be a steel cylinder. Through adopting the metal material to support and fix nib subassembly 10, not only can guarantee certain support strength, avoid the less nib subassembly 10 atress of diameter to take place bending or rupture, improve the life of electric capacity pen, manufacturing cost is also lower moreover. Of course, in other embodiments, the material of the supporting member 21 and the fixing member 22 may be other hard conductive materials.

In this embodiment, as shown in fig. 3 and 4, the nib assembly 10 includes a nib body 11 and a cladding member 12, the cladding member 12 claddes the nib body 11, the insertion portion 212 of the support member 21 is inserted into the insertion cavity of the nib body 11, and the fixing member 22 is sleeved outside the cladding member 12. That is, in this embodiment, the nib assembly 10 adopts a double-layer structure, and the inside nib main body 11 is as the base member to cladding through cladding piece 12 has effectively increased with capacitive screen area of contact, and in addition, outside cladding piece 12 can play the guard action to inside nib main body 11 on the one hand, and on the other hand still can improve and write and experience. In addition, in the present embodiment, the cover 12 is shaped by punching. Of course, in other embodiments, the nib assembly 10 may have a single-layer structure.

Further, in the present embodiment, the material of the pen tip main body 11 is a soft conductive material, and the material of the cladding member 12 is a soft conductive material. Specifically, in the present embodiment, the material of the pen tip main body 11 is conductive rubber, and the material of the covering member 12 is conductive cloth or conductive flannelette. Because the pen point main body 11 and the cladding member 12 have excellent flexibility, good touch feedback hand feeling can be provided during writing, the use experience of a user is further improved, and the pen point assembly 10 can be prevented from being too hard to scratch the capacitive screen. Moreover, since the pen point main body 11 is also conductive, the whole pen point structure 100 is ensured to have excellent conductivity, so that writing is smoother and writing quality is ensured. Of course, in other embodiments, the material of the pen tip main body 11 may be other materials with similar properties to the conductive rubber, and the material of the covering member 12 may also be other materials with flexibility and convenient for covering.
