[0033] In the related art, an electronic pen, also known as a stylus pen, is a tool for touching the screen of an electronic device. For example, the electronic pen can touch the screen of an electronic device such as a mobile phone or a tablet.
[0034] The electronic pen includes a pen body, a nib 100, a battery, and a circuit board. The pen body has a storage cavity 210, and the battery and the circuit board can be placed in the storage cavity 210. An electrode is provided at the nib 100. When the nib 100 touches the screen, the electrode will release an electrical signal, forming a coupling capacitance with the screen surface, so as to be received and recognized as a touch operation by the screen. In the prior art, the nib 100 is entirely made of plastic, and the nib 100 and the pen body are snap-connected. However, the snap connection will cause the connection strength between the nib 100 and the pen body to be too low, and it is easy to become loose, thereby affecting the user's use of the electronic pen. For this reason, the present application proposes an electronic pen.
[0035] Please refer to Figures 1 to 5 , Figure 1 which is a schematic diagram of the nib 100 in the electronic pen of some embodiments of the present utility model; Figure 2 which is a cross-sectional schematic diagram of the nib 100 in the electronic pen of some embodiments of the present utility model; Figure 3 which is a cross-sectional schematic diagram of the insulating member 200 in the nib 100 of the electronic pen of some embodiments of the present utility model; Figure 4 which is a cross-sectional schematic diagram of the conductive member 300 in the nib 100 of the electronic pen of some embodiments of the present utility model; Figure 5Explosion schematic diagram of the nib 100 in an electronic pen according to some embodiments of the present utility model. In some embodiments, the electronic pen includes: a pen body assembly and a nib 100. The pen body assembly includes components such as a pen body, a circuit board, and a battery. The shape of the pen body is cylindrical and can be held by the user. For a stylus, the circuit board can generate stable high-frequency electrical signals. These electrical signals are sent to the touch screen through the nib 100 of the stylus, providing a basis for the interaction between the stylus and the touch screen. The circuit board is also responsible for transmitting the generated electrical signals to the nib 100 of the stylus or other relevant components to ensure that the signals can be accurately transmitted to the touch screen and recognized. Various electronic components and chips on the circuit board work together to achieve various functions of the stylus, such as precise positioning, pressure sensing, tilt angle detection, etc. These functions make the stylus more flexible and precise in writing, drawing, gaming, etc. The circuit board is also responsible for the power management of the battery, including power monitoring, power distribution, and charging control, etc. This helps to ensure that the stylus can work continuously and stably during use. The nib 100 can contact the touch screen, facilitating the user to click, draw, and write on the screen. The following introduces the specific structure of the nib 100. The nib 100 includes: an insulating member 200 and a conductive member 300. The material of the insulating member 200 can be plastic, rubber, ceramic, etc. The insulating member 200 is provided with a storage cavity 210 and a through hole 220, and the through hole 220 communicates with the storage cavity 210. The insulating member 200 is threadedly connected to the pen body assembly. The specific manner of the threaded connection between the insulating member 200 and the pen body assembly will be introduced below. The conductive member 300 is made of conductive plastic material, can conduct electricity, and can contact the screen. The conductive member 300 is disposed in the through hole 220 and is electrically connected to the pen body assembly. Specifically, the conductive member 300 is electrically connected to the electrode in the pen body assembly. After the insulating member 200 of the nib 100 is threadedly connected to the pen body assembly, the engagement of the threads can provide a stable mechanical locking force, thereby ensuring that the nib 100 and the pen body assembly are not easily loosened and separated after connection. In the prior art, the nib 100 and the pen body are connected by a snap-fit method. Therefore, the nib 100 and the pen body are prone to loosening, while the technical solution of the present application can effectively solve this problem. Specifically, the electronic pen is convenient for the user to use. In addition, the threaded connection also has many advantages such as simple structure, reliable connection, convenient installation and disassembly, wide application range, high standardization degree, easy adjustment, low heat influence, and environmental protection and energy saving.
[0036] Further, in some embodiments, the insulating member 200 and the conductive member 300 are formed by an injection molding process. The principle of the injection molding process is to add granular or powdered plastic raw materials into the hopper of the injection molding machine. The raw materials are heated and melted into a flowing state, and then under the push of the screw or piston of the injection molding machine, they enter the mold cavity through the nozzle and the pouring system of the mold, and finally harden and take shape in the mold cavity. Among them, the insulating member 200 and the conductive member 300 can be formed by a two-color injection molding process. That is, first, the insulating member 200 is injection molded. After it is cooled and solidified, the core or cavity is switched, and then the conductive member 300 is injection molded and embedded with the insulating member 200. After cooling and solidifying, the nib 100 is obtained. Or, first, the conductive member 300 is injection molded. After it is cooled and solidified, the core or cavity is switched, and then the insulating member 200 is injection molded and embedded with the conductive member 300. After cooling and solidifying, the nib 100 is obtained. Among them, both the insulating member 200 and the conductive member 300 can be made of plastic material. The difference is that a conductive material is added to the conductive member 300. Further, after the nib 100 is formed by the injection molding process, the production efficiency of the nib 100 is relatively high, thereby making the production efficiency of the electronic pen relatively high. The production cost of the nib 100 is relatively low, thereby making the production cost of the electronic pen relatively low. In addition, the injection molding process can make the insulating member 200 and the conductive member 300 an integral structure, which can make the nib 100 have relatively high strength. Continuing to explain, in the prior art, a relatively thin layer of plastic is wrapped around the metal electrode of the nib 100. Among them, this will cause the nib 100 to have relatively high hardness. Therefore, when the nib 100 is writing on the terminal product, the user's hand feeling is relatively poor, and the sound of the nib 100 hitting the screen when starting to write is relatively loud, affecting the use experience. However, in the present application, since the conductive member 300 and the insulating member 200 can be made of plastic material, the nib 100 will have a relatively soft characteristic, which can improve the writing experience of the user. The setting of the insulating member 200 can also effectively avoid the problem of signal deviation of the nib 100.
[0037] Further, please refer to Figure 2 and Figure 4 , Figure 2 is a cross-sectional schematic view of the nib 100 in the electronic pen according to some embodiments of the present invention; Figure 4Schematic cross-sectional view of the conductive member 300 in the pen tip 100 of the electronic pen in some embodiments of the utility model. In some embodiments, the conductive member 300 includes a main body 310 and two protrusions 320, and the two ends of the main body 310 are respectively connected to the two protrusions 320. The protrusions 320 protrude along the radial direction of the main body 310, that is, the cross section of the conductive member 300 can be approximately in the shape of a "I". The main body 310 is arranged in the through hole 220, and the two protrusions 320 are respectively clamped on the two side edges of the through hole 220. Among them, since the two protrusions 320 can be respectively clamped on the two side edges of the through hole 220, when one end of the conductive member 300 abuts against the touch screen, the conductive member 300 is subjected to pressure, and the arrangement of the protrusions 320 can prevent the main body 310 from sliding in the through hole 220, thereby causing the conductive member 300 to slide relative to the insulating member 200, which can improve the stability of the pen tip 100 in use. In addition, the protrusion 320 can also effectively prevent the body 310 from coming out of the through hole 220, thereby causing failure of the pen tip 100. Specifically, the pen tip 100 has better reliability and a longer service life of the electronic pen.
[0038] Furthermore, the following describes how the conductive member 300 is electrically connected to the pen body assembly. Specifically, in some embodiments, the pen body assembly includes an electrode, and one end of the electrode abuts against one end of the conductive member 300. The pen body assembly includes a circuit board, and the circuit board can be connected to the electrode, and then the electrode can be electrically connected to the conductive member 300. In this way, when the conductive member 300 contacts the touch screen, the communication connection between the electronic pen and the electronic device can be achieved. The following continues to introduce the installation process of the electronic pen. When the pen tip 100 and the pen body are installed, the conductive member 300 and the insulating member 200 are integrally processed and formed. Therefore, during installation, it is only necessary to abut the electrode against the conductive member 300 to achieve the installation of the pen tip 100 and the electrode. This has the characteristics of quick installation and improves the installation efficiency of the electronic pen.
[0039] For further information, please refer to Figure 4 , Figure 4 Schematic cross-sectional view of the conductive member 300 in the pen tip 100 of the electronic pen in some embodiments of the utility model. In some embodiments, the conductive member 300 has an abutting surface 330, and the abutting surface 330 is concavely arranged toward the through hole 220. Specifically, after the electrode abuts on the abutting surface 330, the concave design of the abutting surface 330 can improve the stability of the connection between the conductive member 300 and the electrode, which can effectively avoid the situation of sliding or separation between the electrode and the conductive member 300. It is conceivable that one end of the electrode can be in an arc shape, so as to adapt to the shape of the abutting surface 330.
[0040] For further information, please refer to Figure 4 , Figure 4A cross-sectional view of the conductive member 300 in the nib 100 of the electronic pen according to some embodiments of the present invention. In some embodiments, the conductive member 300 has an arc surface 340, and the arc surface 340 is used to abut against the screen. Specifically, the design of the arc surface 340 may have the following advantages: First, the arc surface 340 can enable the nib 100 to slide more smoothly when writing on the touch screen, reduce resistance, and make the writing more smooth and natural. Second, the arc surface 340 can cause less wear on the touch screen when the nib 100 is used for a long time, which helps to extend the service life of the electronic pen and the touch device. Third, the arc surface 340 can also increase the contact area between the nib 100 and the touch screen, thereby reducing the pressure on the screen under the same pressure and protecting the screen from damage.
[0041] Further, the specific manner of the threaded connection between the insulating member 200 and the pen body assembly will be introduced below. Specifically, please refer to 3. Figure 3 A cross-sectional view of the insulating member 200 in the nib 100 of the electronic pen according to some embodiments of the present invention. In some embodiments, the insulating member 200 is further provided with a threaded hole 230, and the threaded hole 230 communicates with the storage cavity 210. The pen body assembly is threadedly connected to the hole wall of the threaded hole 230. Specifically, an internal thread is provided on the threaded hole 230, and an external thread is provided on the pen body assembly. For example, the pen body assembly includes a bracket located inside the pen body, and the bracket has an external thread. Or, the pen body assembly includes a pen body, and an external thread is provided on the pen body. In this way, after providing the threaded hole 230 on the insulating member 200 and the external thread on the pen body assembly, the threaded connection between the insulating member 200 and the pen body assembly can be realized.
[0042] Further, in addition to the above method, there are other methods for the threaded connection between the insulating member 200 and the pen body assembly. Specifically, in some embodiments, the insulating member 200 is provided with an external thread, and the pen body assembly is provided with an internal thread, and the external thread is connected to the internal thread. Among them, the insulating member 200 is provided with an external thread and the pen body assembly is provided with an internal thread specifically can be that the pen body assembly includes a bracket located inside the pen body, and the bracket has an internal thread. Or, the pen body assembly includes a pen body, and an internal thread is provided on the pen body. In this way, after providing the external thread on the insulating member 200 and the internal thread on the pen body assembly, the threaded connection between the insulating member 200 and the pen body assembly can be realized.
[0043] Further, in some embodiments, the conductive member 300 and the insulating member 200 are of a separable structure, and the conductive member 300 is snap-fitted to the inner wall of the through hole 220. Specifically, the conductive member 300 can be formed by an injection molding process, specifically by adding a conductive material to plastic powder and then injection molding. Among them, the insulating member 200 can also be formed by an injection molding process, specifically by injection molding with plastic powder. After the conductive member 300 and the insulating member 200 are respectively injection molded, the conductive member 300 can be disposed in the through hole 220 so as to be snap-fitted to the inner wall of the through hole 220. When one of the conductive member 300 or the insulating member 200 is damaged, it can be removed and then replaced, which facilitates maintenance.
[0044] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made without departing from the spirit of the present invention within the knowledge scope of those of ordinary skill in the art. In addition, the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.
