[0027] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0028] The following is combined with Figure 1-4 This application is described in further detail.

[0029] The first embodiment of the utility model provides a novel pen tip structure, referring to Figure 1 , including a fixing rod 100, one end of which is provided with a ball head 110, the ball head 110 is made of metal. When the new pen tip structure touches the screen, the ball head 110 can generate an electric field, and then the screen can read the change of the electric field, thereby displaying the picture.

[0030] It is understandable that in some embodiments of the present invention, reference Figure 1 The new pen tip structure also includes a wear-resistant part 200, which is coated on the outside of the ball head 110. The wear-resistant part 200 is used to contact the screen to prevent the ball head 110 from directly contacting the screen and causing damage to the screen. Specifically, the wear-resistant part 200 is a fiber material, or a conductive cloth material, or a TPU material. The above materials are wear-resistant and soft. Compared with the materials with higher hardness such as plastic, graphite, ceramic, and metal used in the related art, the friction coefficient is larger during writing, thereby improving the writing experience, and due to its soft nature, it can reduce the damage to the screen.

[0031] It is understandable that in some embodiments of the present invention, reference Figure 1The novel pen tip structure also includes a plastic part, which is located at one end of the fixed rod 100 close to the ball head 110, and is used to fix the wear-resistant part 200 to the fixed rod 100. Specifically, the plastic part includes a plastic sleeve 310, which is sleeved on the fixed rod 100, and a slot for accommodating the wear-resistant part 200 is formed between one end of the plastic sleeve 310 and the fixed rod 100. When the wear-resistant part 200 is assembled to cover the ball head 110, the wear-resistant part 200 is inserted into the slot, and the plastic sleeve 310 generates elastic deformation to avoid the wear-resistant part 200, so that the plastic sleeve 310 uses the elastic reset force to press the wear-resistant part 200, and then fix the wear-resistant part 200 to the fixed rod 100.

[0032] It is understandable that in some embodiments of the present invention, reference Figure 1 The novel pen tip structure further includes a metal ring 320, which is located in the slot and fixedly connected to the plastic sleeve 310. When the wear-resistant part 200 is assembled into the slot, the metal ring 320 is located between the plastic sleeve 310 and the wear-resistant part 200. The metal ring 320 fixes the wear-resistant part 200 through a clamping structure, so that the relative position between the wear-resistant part 200 and the fixed rod 100 is more stable.

[0033] It can be understood that in some embodiments of the present invention, the clamping structure includes a plurality of clamping edges, and the plurality of clamping edges are distributed at intervals along the circumference of the metal ring 320. The wear-resistant part 200 is provided with a plurality of clamping grooves, and the plurality of clamping grooves are respectively correspondingly clamped and matched with the plurality of clamping edges. Therefore, when the wear-resistant part 200 is assembled to cover the ball head 110, the wear-resistant part 200 is inserted into the slot. At this time, the clamping edge abuts against the metal ring 320, so that the plastic sleeve 310 generates elastic deformation to avoid the clamping edge. When the clamping edge is aligned with the clamping groove, the plastic sleeve 310 uses the elastic reset force to make the clamping edge and the clamping groove clamped and matched, thereby fixing the wear-resistant part 200 to the fixing rod 100.

[0034] The implementation principle of the embodiment of the first aspect of the present application is: by covering the wear-resistant part 200 on the ball head 110 of the fixed rod 100, the wear-resistant part 200 is inserted into the slot, and the clamping edge abuts the metal ring 320 at this time, so that the plastic sleeve 310 generates elastic deformation to avoid the clamping edge, and when the clamping edge is aligned with the clamping groove, the plastic sleeve 310 uses the elastic reset force to make the clamping edge and the clamping groove clamp together, thereby fixing the wear-resistant part 200 to the fixed rod 100, so that during use, the wear-resistant part 200 is not easy to fall off the fixed rod 100, so that the wear-resistant part 200 can be used to improve the friction coefficient of the pen tip, thereby improving the user's writing experience, thereby solving the problem in the related art that the magnetic paper film will cause the pen tip to wear faster, and then easily cause irreversible damage to the screen.

[0035] The electronic pen provided in the second embodiment of the utility model is as follows: Figure 2 and Figure 3 , the electronic pen includes the novel pen tip structure in the above-mentioned first aspect embodiment. The electronic pen also includes a pen body 500 and a pen core assembly. A cavity is provided inside the pen body 500, and the cavity runs through both ends of the pen body 500. The pen core assembly is accommodated in the cavity. In some embodiments, the pen core assembly includes a main bracket 610, and the main bracket 610 is arranged in the cavity so that the main bracket 610 provides support for the pen core assembly. It should be noted that, in some embodiments, the pen body 500 is coated on the outside of the main bracket 610 by injection molding, so that the main bracket 610 and the pen body 500 can fit better.

[0036] It is understood that in some embodiments of the present invention, reference Figure 2 and Figure 3 The electronic pen structure further includes a locking member, which is located at one end of the pen body 500 and can fix one end of the pen body 500 to the main bracket 610. Specifically, the locking member includes a locking sleeve 710, and the locking sleeve 710 is provided with an external thread 711. The main bracket 610 is provided with a first screw hole 611 at one end close to the locking sleeve 710, and the external thread 711 is threadedly matched with the first screw hole 611. A limiting edge 712 is provided on the outside of the locking sleeve 710, and a convex edge 510 is provided on the inside of the pen body 500. The convex edge 510 can be located between the main bracket 610 and the limiting edge 712. When it is necessary to fix the pen body 500 and the main bracket 610, one end of the convex edge 510 is abutted against the main bracket 610, and one end of the locking sleeve 710 with an external thread 711 is threadedly engaged with the first screw hole 611, so that the locking sleeve 710 drives the limiting edge 712 to abut against the other end of the convex edge 510 to clamp the convex edge 510, thereby fixing the relative position of the pen body 500 and the main bracket 610.

[0037] It is understood that in some embodiments of the present invention, reference Figure 3 and Figure 4 The refill assembly also includes a main board 620, a movable rod 630 and an elastic member. The main board 620 is arranged in the main bracket 610. The main bracket 610 is provided with an movable cavity 612. The movable cavity 612 is connected to the first screw hole 611. The movable rod 630 is movably arranged in the movable cavity 612. The elastic member can provide elastic force for the movable rod 630 and limit the movable rod 630 to reduce the situation where the movable rod 630 is separated from the movable cavity 612.

[0038] It is understood that in some embodiments of the present invention, reference Figure 3 and Figure 4The elastic member includes a spring 641, which is sleeved outside the movable rod 630. The cavity wall of the movable cavity 612 is provided with a receiving cavity 6121 for receiving the elastic member. The movable rod 630 is provided with an abutting edge 632. One end of the spring 641 abuts against the abutting edge 632, and the other end abuts against the cavity wall of the receiving cavity 6121. In a free state, the spring 641 is in a compressed state, so that the spring 641 can continuously apply a force to the abutting edge 632 in a direction in which the movable rod 630 is away from the locking sleeve 710, so as to reduce the situation in which the movable rod 630 is separated from the movable cavity 612.

[0039] It is understood that in some embodiments of the present invention, reference Figure 3 and Figure 4 The movable rod 630 has a second screw hole 631 at one end close to the first screw hole 611, and the second screw hole 631 is connected to the first screw hole 611. The end of the fixed rod 100 away from the ball head 110 can pass through the first screw hole 611, and the end passing through the first screw hole 611 is threadedly engaged with the second screw hole 631, so that the new pen tip structure is fixed to the movable rod 630 through the fixed rod 100. In some embodiments, referring to Figure 3 A limiting groove 400 is provided at one end of the plastic sleeve 310 close to the pen body 500, and a limiting portion 713 is provided at one end of the locking member away from the external thread 711. The limiting portion 713 is plugged into and matched with the limiting groove 400 to limit the radial movement of the plastic sleeve 310 relative to the pen body 500 along the pen body 500, thereby further limiting the moving position of the plastic sleeve 310.

[0040] It is understood that in some embodiments of the present invention, reference Figure 3 and Figure 4 A pressure sensor 800 is provided between the main board 620 and the movable rod 630. The pressure sensor 800 is used to sense the pressure between the main board 620 and the movable rod 630 and output a corresponding sensing signal to the main board 620. In the free state of the electronic pen structure, the spring 641 is in a compressed state, so that the spring 641 drives the abutting edge 632 to continuously abut against the pressure sensor 800, so that the pressure sensor 800 exerts a force on the movable rod 630 toward the fixed rod 100, thereby creating a gap between the plastic sleeve 310 and the pen body 500, and a gap between the limiting portion 713 and the bottom of the limiting groove 400. When the new pen tip structure is in use, the wear-resistant part 200 presses against the screen, so that the wear-resistant part 200 drives the fixed rod 100 to push the movable rod 630, so that the movable rod 630 presses against the pressure sensor 800. Therefore, according to the different writing needs of the user when using the electronic pen, the pressure of the new pen tip structure on the pressure sensor 800 also changes accordingly, so that the pressure sensor 800 transmits the sensing signal to the mainboard 620.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
