Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of touch pens, and in particular to a touch pen head assembly with concentrated electric charge and a touch pen thereof. Background Art
[0002] With the advancement of technology, touch technology has been widely used in various electronic devices, especially smart phones, tablet computers and touch screen displays, and more and more people like to use mobile phones, tablet computers and other electronic devices for note taking or drawing. As an important input tool, the stylus provides users with a more accurate and convenient touch experience. In order to enable users to obtain a better writing and drawing experience, the demand for stylus is also increasing.
[0003] In the working principle of the stylus, capacitance change is the key factor in its recognition of touch input. When the tip of the stylus approaches or touches the capacitive screen, it will cause the electric field distribution on the screen to change, which will then be recognized as touch input by the sensor inside the screen.
[0004] In order to increase the service life, protection and texture of the stylus in the prior art, some metal materials are mostly used as the pen tip. However, in the application of the stylus, the metal pen tip may cause a series of problems. Specifically, when the conductive pen core is installed in the metal pen tip, the metal pen tip will quickly disperse the charge to the entire pen tip due to its good conductivity. This charge dispersion phenomenon makes it impossible for the screen to detect obvious capacitance changes, because the capacitance change is identified based on the concentration of charge at a specific point.
[0005] Therefore, in the prior art, using a metal pen tip will significantly affect the touch performance of the stylus on the capacitive screen. Since the screen cannot recognize the input of the stylus, the user will not be able to write, draw or perform other touch operations on the screen, thereby greatly reducing the efficiency of using the stylus and the user experience. Summary of the invention

DETAILED DESCRIPTION
[0030] The present invention will now be further described in detail in conjunction with the accompanying drawings and embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.
[0031] like Figure 1 and Figure 2 As shown, a charge-concentrated stylus pen tip assembly comprises: a core component 1, used for transmitting electrical signals in the stylus for writing; an isolation sleeve 2, used for mounting the core component 1 and isolating the charge between the core component 1 and the metal part, the isolation sleeve 2 is a hollow structure, the core component 1 is mounted on the inner wall of the isolation sleeve 2, and the inner wall of the isolation sleeve 2 is provided with an insulating layer 4; a tip component 3, wherein an axial hole component is opened inside the tip component 3, the axial hole component passes through the inside of the tip component 3 to both ends, and the isolation sleeve 2 is mounted on one end of the tip component 3.
[0032] It should be noted that the material of the isolation sleeve 2 is preferably plastic; the material of the insulating layer 4 is one of rubber, plastic, fiber, glass or ceramic, preferably rubber as the material of the insulating layer 4, and at the same time, a certain friction force can be provided for the installation of the core component 1; by forming the stylus pen tip assembly from the core component 1, the isolation sleeve 2 and the tip component 3, the core component 1 can be installed to one end of the isolation sleeve 2, and the isolation sleeve 2 and the core component 1 can be installed to one end of the tip component 3 for use. When the material of the tip component 3 is made of metal material in order to improve the service life, protection and texture of the stylus, with the cooperation of the insulating layer 4 on the inner wall of the isolation sleeve 2, when the electrical signal in the stylus is transmitted to the core component 1, the charge can be avoided from being dispersed to the isolation sleeve 2 and the tip component 3, so that the charge can be concentrated on the core component 1 for output, thereby preventing the touch performance of the stylus on the capacitive screen from being affected by the charge dispersion, thereby improving the use efficiency of the stylus and the user experience effect.
[0033] like Figure 2 and Figure 3 As shown, in some embodiments, the isolation sleeve 2 includes: a conical column 21, a fixed column 22 fixed at the end of the conical column 21 with a smaller diameter, and a plug-in column 23 fixed at the end of the conical column 21 with a larger diameter; the inclined edge of the conical column 21 faces the side of the fixed column 22, the diameter of the right-angled side of the conical column 21 is larger than the diameter of the plug-in column 23, and a retaining ring 24 is fixed to the side of the plug-in column 23 near one end.
[0034] It should be noted that the material of the clamping ring 24 is a flexible material, preferably rubber, and the two sides connected to the plug-in column 23 are both inclined; when the core component 1 is installed on the isolation sleeve 2 and in contact with the insulating layer 4, the plug-in column 23 and the clamping ring 24 can be plugged into one end of the pen head component 3. Since the diameter of the right-angled side of the conical column 21 is larger than the diameter of the plug-in column 23, when the plug-in column 23 is extended into one end of the pen head component 3, one side of the conical column 21 will overlap with one end of the pen head component 3, thereby limiting the depth of insertion.
[0035] In some embodiments, the refill component 1 includes: a conductive connecting handle 11, and a conductive contact 12 fixed to one end of the conductive connecting handle 11; the side surface of the conductive connecting handle 11 and the inner wall of the isolation sleeve 2 are interference fit.
[0036] It should be noted that the conductive connecting handle 11 and the isolation sleeve 2 are both coaxially arranged with the pen head component 3; the conductive connecting handle 11 and the conductive contact 12 are both made of flexible conductive material or metal material in one piece. By making the conductive connecting handle 11 and the conductive contact 12 of flexible conductive material, firstly, the conductive contact 12 can transmit the electrical signal in the stylus pen to ensure that the user will not experience current interruption during use; secondly, the softness and elasticity can ensure that the user will not make noise when writing or drawing, and provide the user with sufficient damping feeling, so that the user has a better, more delicate and more realistic writing and drawing experience. The side of the conductive connecting handle 11 and the inner wall of the isolation sleeve 2 are interference fit, so that after the conductive connecting handle 11 is clamped on the inner wall of the isolation sleeve 2, it is not easy to fall off during use, thereby improving the reliability of the stylus.
[0037] Among them, the flexible conductive material is preferably conductive rubber. Conductive rubber is made by evenly distributing conductive particles such as glass silver-plated, aluminum silver-plated, and silver in silicone rubber, and making the conductive particles contact through pressure to achieve good conductive properties. It has good electromagnetic sealing and water vapor sealing capabilities, and can provide good conductivity under a certain pressure. The conductive rubber is made of good conductivity and long service life, and can provide sufficient damping, so that users have a better, more delicate and more realistic writing and painting experience.
[0038] like Figure 4 As shown, in some embodiments, the axial hole component includes: a first axial hole 5, a second axial hole 51 and a third axial hole 52, which are sequentially opened inside the pen head component 3 from left to right; the side of the plug-in column 23 is inserted into the inner side of the first axial hole 5, and the side of the retaining ring 24 is in contact with the inner side of the first axial hole 5.
[0039] It should be noted that the diameter of the first axial hole 5 is smaller than that of the second axial hole 51 and the third axial hole 52 respectively; the first axial hole 5 is used to dock with the plug-in column 23. When the plug-in column 23 is plugged into the inner wall of the first axial hole 5, the retaining ring 24 on the side of the plug-in column 23 will contact the inner wall of the first axial hole 5 to achieve an interference fit and improve the connection reliability. The third axial hole 52 is used to dock with the pen holder of the stylus pen, and the second axial hole 51 is used to connect the first axial hole 5 and the third axial hole 52; if the electronic device on the pen holder needs to dock with one end of the conductive connecting handle 11, it can pass through the second axial hole 51 through the third axial hole 52, so as to dock with the conductive connecting handle 11 in the first axial hole 5.
[0040] In some embodiments, an internal thread 6 is provided on the inner side of the third axial hole 52 for detachably connecting the pen shaft; by providing the internal thread 6 on the inner side of the third axial hole 52, the pen shaft of the stylus pen can be detachably connected to the inner side of the third axial hole 52 through the cooperation of the internal thread 6. When the user needs to replace the pen head assembly or the pen shaft separately, it is convenient to disassemble and install, thereby improving the convenience during use and the user's personalized replacement.
[0041] A stylus pen comprises any one of the stylus pen head components described above.
[0042] In some embodiments, one end of the pen shaft of the stylus pen is connected to one end of the pen head component 3 through an axial hole component.
[0043] When the utility model is used, when the user assembles, the conductive connecting handle 11 is interference-fitted on the inner side of the isolation sleeve 2 and contacts the insulating layer 4, and the plug-in column 23 is plugged into the inner wall of the first axial hole 5. During the plug-in process, the snap ring 24 on the side of the plug-in column 23 will contact the inner wall of the first axial hole 5 to achieve an interference-fit connection. Since the diameter of the right-angled side of the tapered column 21 is larger than the diameter of the plug-in column 23, when the plug-in column 23 is inserted into one end of the pen head component 3, one side of the tapered column 21 will overlap with one end of the pen head component 3, thereby limiting the insertion depth. The inner side of the third axial hole 52 is used to prevent the plug-in column 23 from being inserted into the pen head component 3. The thread 6 can be used to detachably connect the pen holder of the stylus pen to the inner side of the third axial hole 52 through the cooperation of the internal thread 6. When the material of the pen head component 3 is made of metal material in order to improve the service life, protection and texture of the stylus pen, with the cooperation of the insulating layer 4 on the inner wall of the isolation sleeve 2, when the electrical signal in the stylus pen is transmitted to the core component 1, it can avoid the charge from being dispersed to the isolation sleeve 2 and the pen head component 3, so that the charge can be concentrated on the core component 1 for output, thereby preventing the touch performance of the stylus pen on the capacitive screen from being affected by the charge dispersion, thereby improving the use efficiency of the stylus pen and the user experience effect.
