[0036] The utility model proposes a touch pen, which aims to optimize the damping feeling when the pen tip contacts the touch screen, so as to provide a more natural touch, writing and drawing experience. Figures 1 to 10 The present invention is a schematic structural diagram of an embodiment of the touch pen provided by the present invention.
[0037] Please refer to Figures 1 to 10 The utility model provides a touch pen 100, comprising a pen body 1 and a pen tip 2, wherein the pen tip 2 is detachably arranged at one end of the pen body 1, and the pen tip 2 is formed with a contact end surface 21 for contacting a touch screen, and the contact end surface 21 is provided with a plurality of fiber bundles 3, and the plurality of fiber bundles 3 are unevenly arranged on the contact end surface 21, and the fiber bundles 3 are in a granular structure or an unequal granular structure on the contact end surface 21.
[0038] The above-mentioned granular structure is a structure in which a number of granular fiber bundles are bonded together to form an agglomerate. There are tiny gaps between the single particles or other substances such as curing agents are filled. The above-mentioned unequal particle structure refers to a structure composed of particles of various sizes. In the unequal particle structure, there is an obvious hierarchical relationship between particles of different sizes, and the upper particles are composed of the lower particles to form a structure.
[0039] Based on the stylus pen 100 proposed in the utility model, this solution also proposes a manufacturing process method for the pen tip 2 in the stylus pen 100. Specifically, because the main body of the pen tip 2 is made of fiber bundles 3, they are longitudinally cured and bonded together after being mixed with a resin curing agent, and then formed at high temperature. The curing agent that plays a bonding and molding role will destroy the basic properties of the fiber material such as softness, elasticity and wear resistance after molding, and the process causes stress between the fiber bundles 3, resulting in a certain sense of friction during the use of the pen tip 2, but the damping property needs to be improved. In view of this, the process first places the contact end of the pen tip 2 into a grinding fixture and uses a soft contoured felt wheel for surface treatment. The contact end surface of the pen tip 2 is attached to the contoured felt wheel and rotated in opposite directions to perform a grinding action. The felt wheel is soft and will not damage the structure of the pen tip 2. At the same time, a resin solvent is dripped into the contoured felt wheel. The contoured felt wheel evenly applies the solvent to the contact end. This process takes 3-10 minutes. The pen tip 2 is taken out and placed at room temperature for 5-15 minutes. The pen tip 2 is placed in the grinding fixture again, and a clean felt wheel is replaced for water grinding to remove the dissolved resin at the contact end. The resin solvent includes alcohols, ketones, esters or acids and bases. The contact end surface 21 of the pen tip 2 produced by this process will form a number of fiber bundles 3. This meticulous microscopic structure effectively releases the internal stress between the fiber bundles 3 on the contact end surface in the longitude and latitude directions, so that the fiber bundles 3 constituting the above structure restore the basic properties of the fiber material such as flexibility, elasticity and wear resistance. The force surface (point) at the contact end of the pen tip 2 is given a more moderate damping coefficient, and a better damping feeling is obtained. Furthermore, the chemical fiber oil can be dripped into the contoured felt wheel, and the contoured felt wheel can be used to evenly apply the chemical fiber oil to the contact end surface of the pen tip 2. This process takes 5-10 minutes. This step effectively improves the smoothness, clustering and flexibility of the above-mentioned microscopic and meticulous structure.
[0040] In the technical solution of the utility model, a stylus pen 100 is proposed, which includes a pen body 1 and a pen tip 2. The pen tip 2 is detachably arranged at one end of the pen body 1. The pen tip 2 forms a contact end face for contacting a touch screen. The contact end face is provided with a contact end face 21. The contact end face 21 is provided with a plurality of fiber bundles 3. The plurality of fiber bundles 3 are unevenly arranged on the contact end face 21. The plurality of fiber bundles 3 are generated by a solvent reacting with the contact end face 21 to release the internal stress of the contact end face 21. When the internal stress of the contact end face 21 is released, it will have a relatively moderate hardness. While ensuring the structural strength of the pen tip 2, it also provides a certain degree of flexibility to increase the damping feeling of the pen tip 2. When the user uses the stylus pen 100 to click or swipe on the touch screen, a plurality of fiber bundles 3 will also contact the touch screen to increase the contact area between the two, increase the friction resistance, and thus optimize the damping feeling, so as to provide a more natural touch, writing and drawing experience.
[0041] The contact end surface 21 of the pen tip 2 of the stylus pen 100 produced by the above processing technology has a variety of microstructures. The present invention does not limit the specific shape of the microstructure. In the first embodiment of the present invention, please refer to Figure 5 The shape of the fiber bundle 3 is spherical or hemispherical. The fiber bundle 3 releases the internal stress of the pen tip 2, thereby improving its flexibility. The spherical and hemispherical fiber bundle 3 further increases the contact area between the pen tip 2 and the touch screen, thereby increasing its damping feeling.
[0042] In the second embodiment of the present invention, please refer to Figure 6 The shape of the fiber bundle 3 is columnar. It should be noted that the fiber bundle 3 can be cylindrical, prism-shaped, or other irregular columnar shapes. The utility model does not limit this. In one embodiment of the utility model, the fiber bundle 3 is cylindrical. The cylindrical fiber bundles 3 are staggered, which releases the internal stress of the pen head 2. The columnar microstructure also further increases the contact area with the touch screen, thereby optimizing the user experience.
[0043] In the third embodiment of the present invention, please refer to Figure 7 The fiber bundle 3 is in the shape of a needle, and a plurality of needle-shaped fiber bundles 3 are arranged alternately with each other. The needle-shaped fiber bundles 3 can also be fluffy. The needle-shaped structure further increases the contact area between the pen tip 2 and the touch screen, thereby optimizing the user experience.
[0044] In the fourth embodiment of the present invention, please refer to Figure 8, the fiber bundle 3 is in the shape of a ball or floc, and such a design helps to increase the contact area between the pen tip 2 and the screen, thereby enhancing the sense of contact damping and providing a more stable writing and drawing experience. This structure can simulate the texture of real brushstrokes, making the user feel more natural and closer to the feeling of using a traditional pen when using the stylus 100. At the same time, this design also helps to disperse the pressure on the pen tip 2, reduce the wear of the pen tip 2, and extend the service life of the pen tip 2. In addition, the ball-like or floc-like structure can also better adapt to the curve of the screen and maintain continuous contact with the screen, which is also beneficial for improving the accuracy and sensitivity of touch.
[0045] In the fifth embodiment of the present invention, please refer to Fig. 9 A number of irregular particles are formed on the surface of the contact end face 21. The irregular particles can be tiny protrusions or particle structures of any shape. The irregular particles can increase the contact area between the pen tip 2 and the touch screen and release the internal stress of the pen tip 2, thereby optimizing its damping sense and enhancing the user's writing touch experience.
[0046] In the sixth embodiment of the present utility model, the fiber bundle 3 is a powder structure or a crystalline structure. When the fiber bundle is a crystalline structure, it can be a fine-grained structure or a coarse-grained structure. The grain size of the fine-grained structure is slightly smaller, and the grain size of the coarse-grained structure is larger than the fine-grained structure. The crystalline structure is beneficial to increasing the contact damping feeling between the pen tip 2 and the touch screen.
[0047] In the pen body 1 structure of the stylus pen 100 proposed in the present invention, the pen body 1 includes a shell 11, a battery 12 and a circuit board 13. The shell 11 forms an isolated accommodating chamber 112 and an installation chamber 113. The accommodating chamber 112 is provided with a mounting bracket 4. The mounting bracket 4 is provided with two accommodating chambers, namely a first accommodating chamber 41 and a second accommodating chamber 42. The two accommodating chambers are arranged at intervals and are respectively used to install different circuit boards 13. The bottom wall of the installation chamber 113 is provided with a contact portion, which is connected to the accommodating chamber 112 and abuts against an end of the pen head 2 facing away from the contact end surface. The battery 12 is arranged in the accommodating chamber 112, and the circuit board 13 is arranged in the accommodating chamber of the mounting bracket 4 and is located in the accommodating chamber 112. The circuit board 13 is electrically connected to the battery 12 and the contact portion respectively. The mounting bracket 4 is bonded to the inner wall of the shell 11.
[0048] In one embodiment, a magnetic attraction portion 14 is provided on one side of the pen body 1. For details, please refer to Figure 2 , Figure 4 as well as Fig.10, the magnetic attraction portion 14 allows the stylus 100 to be directly adsorbed on the edge of devices such as the iPad, which is convenient for carrying and storage and reduces the risk of loss. Secondly, the magnetic attraction portion 14 can realize the wireless charging function, so that users do not need additional charging cables or charging compartments, which improves the convenience of use. In addition, the design of the magnetic attraction portion 14 also enhances the technological sense and aesthetics of the stylus 100. Furthermore, the outer peripheral wall of the shell 11 is formed with a recessed portion 111 opposite to the magnetic attraction portion 14, and the recessed portion 111 can reduce the wall thickness at the magnetic attraction portion 14 and reduce the magnetic field loss. It should be noted that the pen tip 2 can be fixed to the pen body 1 by a snap-on method or by a magnetic method, and the utility model does not limit this. In one embodiment of the utility model, the pen tip 2 is fixed by an interference fit method, and the outer diameter of the mounting end 22 is slightly larger than the inner diameter of the mounting cavity 113. The mounting end 22 of the pen tip 2 is snap-on in the mounting cavity 113, and the mounting end 22 is provided with a metal contact 23, which is connected to the sensor of the pen tip for detecting angle and force. Specifically, there is a small metal block at the top of the pen tip, and it is as close to the screen as possible. This sensor should be connected to two styluses to measure the force of the pen and the angle with the screen. These components are connected to the circuit board inside the pen body, so that the pen tip can interact accurately with the iPad screen to realize functions such as pressure sensing and tilt detection. Therefore, the capacitor connection of the components on the pen tip and the pen body is mainly to realize these advanced touch functions.
