Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of touch pens, and in particular to a pen core, a touch pen and an intelligent terminal. Background Art
[0002] Users can use electronic pens to write on touch screens of terminal devices such as mobile phones and tablets to improve the convenience of human-computer interaction. While electronic pens bring users a convenient experience of electronic writing, users have also put forward higher and higher requirements for the writing experience of electronic pens. As we all know, when traditional writing tools such as pencils and pens are written on paper, under the pressure of the hand, appropriate friction is generated between the pen core and the paper, resulting in a better writing experience. When the electronic pen writes on the touch screen, the writing vibration and resistance are both weak, which is quite different from the feeling of traditional paper writing. Utility Model Content
[0003] The main purpose of the utility model is to provide a pen core, a touch pen and an intelligent terminal, so as to achieve that the writing feeling of the electronic pen on the touch screen can be comparable to the writing feeling of the traditional writing tool on the paper.
[0004] To achieve the above-mentioned purpose, the pen core proposed in the utility model has conductivity, and includes main fibers and coagulated fibers. The melting point of the coagulated fibers is lower than the melting point of the main fibers. The main fibers and the coagulated fibers are twisted and entangled with each other. After the coagulated fibers are coagulated, the main fibers are bonded and solidified to form the pen core body.
[0005] In one embodiment, there are gaps between the main fibers.
[0006] In one embodiment, the hardness of the pen core is in the range of 45HA-90HA.
[0007] In one embodiment, the dielectric constant of the pen core is in the range of 75Ω-860Ω.
[0008] In one embodiment, the friction coefficient of the pen core is in the range of 0.25 to 0.36.
[0009] In one embodiment, the refill body includes an input portion formed at an end of the refill body and a mounting portion connected to the input portion.
[0010] In one embodiment, a diameter of at least a portion of the input portion is larger than a diameter of the mounting portion.
[0011] In one embodiment, the input portion is spherical, conical, or truncated cone-shaped.
[0012] The utility model also provides a touch pen, comprising the pen core and a pen holder as described above, wherein the pen core is fixed to the pen holder, and the pen holder is conductive and electrically connected to the pen core.
[0013] The utility model also provides an intelligent terminal, wherein the intelligent terminal is connected to the electronic pen as an input device.
[0014] The technical solution of the utility model is to use at least two fibers with different melting points to be longitudinally intertwined to form a fiber column. The fiber in the column state has a certain physical and mechanical structure. This mechanical structure has a good damping feeling. The low-melting point fiber is then melted by high temperature. After the low-melting point fiber is condensed, it is bonded to the remaining fibers to form a fiber rod. The rod maintains the physical and mechanical structure of the fiber column, while not destroying the molecular structure of the remaining fiber filaments, so that the fiber column remains smooth and the fiber aggregate has a basic characteristic of large friction on a smooth surface. The basic characteristic refers to the damping and feel of a square cloth made of fibers wiping on a smooth desktop or glass. The damping feeling of the pen core is close to the moderate damping feeling when used on an electronic screen device, and the feel of use is similar to the traditional real writing feel.

[0027] As we all know, when traditional writing tools such as pencils and pens are used to write on paper, the pressure of the hand creates appropriate friction between the pen core and the paper, which results in a better writing experience. However, when an electronic pen is used to write on a touch screen, the writing vibration and resistance are both weak, which is quite different from the feeling of writing on traditional paper.
[0028] Existing stylus pen tips are made of materials such as metal, hard plastic, and soft rubber. Pen tips made of metal, hard plastic and other materials write smoothly, but the material is too hard, and the screen impact sound is too loud, affecting the user's writing experience. Long-term use will cause damage to the screen. Although the pen tip made of soft rubber material has a small screen impact sound, the damping is large, resulting in poor writing smoothness. At the same time, the pen tip is easily deformed and causes accidental touches, and the rubber material is not wear-resistant and has a short service life. Therefore, it is difficult for pen tips made of existing materials to fully meet user needs and experience.
[0029] In order to achieve the writing feeling of the electronic pen on the touch screen comparable to the writing feeling of traditional writing tools on paper.
[0030] The utility model provides a pen core.
[0031] See also Figure 1 In one embodiment of the utility model, the pen core is conductive, and includes a main fiber 11 and a coagulation fiber 12. The melting point of the coagulation fiber 12 is lower than the melting point of the main fiber 11. The main fiber 11 and the coagulation fiber 12 are twisted and entangled with each other. After the coagulation fiber 12 is coagulated, the main fiber 11 is bonded and solidified to form the pen core body 1.
[0032] The technical solution of the utility model adopts at least two fibers with different melting points to be longitudinally intertwined to form a fiber column. The fiber in the column state has a certain physical and mechanical structure, and this mechanical structure has a good damping feeling. Then, the low-melting point fiber is melted by high temperature, and the low-melting point fiber is bonded to the remaining fibers after condensation to form a fiber rod. The rod maintains the physical and mechanical structure of the fiber column, while not destroying the molecular structure of the remaining fiber filaments, so that the fiber column remains smooth and the fiber aggregate has the basic characteristics of greater friction on a smooth surface. The basic characteristics refer to the damping and feel of a square cloth made of fibers when wiped on a smooth desktop or glass. The damping feeling of the pen core is close to the moderate damping feeling when used on an electronic screen device, and the feel of use is similar to the traditional real writing feel.
[0033] In this embodiment, the pen core can be manufactured by the following method:
[0034] At least two fibers with different melting points are selected, and the fiber with the lowest melting point is selected as the coagulation fiber 12, and the remaining fibers are selected as the main fiber 11. The coagulation fiber 12 and the main fiber 11 are mixed, and a large number of mixed fiber filaments are fixed at one end and twisted at the other end through high-speed rotation. The twisting motion makes the large number of mixed fiber filaments entangle with each other to form a linear column.
[0035] The fiber line column is heated to melt the fibers with lower melting points, and after cooling, the fibers with lower melting points condense to connect the remaining fibers to form a fiber rod body. Subsequently, the fiber rod body is cut, polished, dried, and cut again to obtain the pen core.
[0036] In this embodiment, at least two fibers are longitudinally entangled with each other through twisting and high-speed rotational motion to form a fiber column. The columnar fiber has a certain physical and mechanical structure. This mechanical structure has a good damping feeling while not destroying the molecular structure of the main fiber 11, so that the columnar fiber column remains smooth and the fiber aggregate has a basic characteristic of greater friction on a smooth surface. The basic characteristic refers to the damping and feel of a square cloth made of fibers wiping on a smooth desktop or glass, thereby improving the writing feel of the pen core of the utility model.
[0037] In one embodiment, the coagulation fibers 12 entangled with the main fibers 11 are in a liquid state when melted, lose their original shape, flow or wet, and after coagulation, gaps 13 are generated between the main fibers 11. This provides deformation space for the main fibers 11, thereby improving the writing feel of the pen core.
[0038] In one embodiment, the friction coefficient of the pen core is in the range of 0.25 to 0.36. Thus, when the electronic pen including the pen core writes on the touch screen, the interface roughness is appropriate, the writing resistance generated by friction is greater than that of a conventional electronic pen, and during writing, the high molecular polymer fiber hits the touch screen to generate a vibration feeling, which is basically close to the traditional paper writing experience.
[0039] In one embodiment, the hardness of the pen core is in the range of 45HA-90HA. The pen core is moderately soft and hard, and has the feel of a pencil when writing.
[0040] In one embodiment, the dielectric constant of the pen core is in the range of 75Ω-860Ω. In this way, the capacitance value of the pen tip is relatively high. When it is used in a capacitive electronic pen, it can generate a sufficiently large signal to interact with the touch screen, display words on the screen or realize preset functions, etc. The dielectric constant here refers to the relative dielectric constant of the pen tip relative to air.
[0041] See also Figures 1 to 5 In one embodiment, the refill body 1 includes an input portion 14 formed at the end of the refill body 1 and a mounting portion 15 connected to the input portion 14. The input portion 14 is used for writing on the screen.
[0042] In one embodiment, the diameter of at least a portion of the input portion 14 is greater than the diameter of the mounting portion 15. Specifically, the input portion 14 may be spherical, conical, or truncated cone-shaped.
[0043] The utility model also provides a stylus pen, which includes the above-mentioned pen core and pen holder, wherein the pen core is fixed to the pen holder, and the pen holder is conductive and electrically connected to the pen core. The specific structure of the pen core refers to the above-mentioned embodiment. Since the stylus pen adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here.
[0044] The utility model also provides an intelligent terminal, wherein the intelligent terminal is connected to the electronic pen as an input device.
[0045] The technical solution of the utility model is to use at least two fibers with different melting points to be longitudinally intertwined to form a fiber column. The fiber in the column state has a certain physical and mechanical structure. This mechanical structure has a good damping feeling. The low-melting point fiber is then melted by high temperature. After the low-melting point fiber is condensed, it is bonded to the remaining fibers to form a fiber rod. The rod maintains the physical and mechanical structure of the fiber column, while not destroying the molecular structure of the remaining fiber filaments, so that the fiber column remains smooth and the fiber aggregate has a basic characteristic of large friction on a smooth surface. The basic characteristic refers to the damping and feel of a square cloth made of fibers wiping on a smooth desktop or glass. The damping feeling of the pen core is close to the moderate damping feeling when used on an electronic screen device, and the feel of use is similar to the traditional real writing feel.
