Description

Technical Field

[0001] This utility model relates to the field of capacitive pen tips, and in particular to a universal, multi-functional, replaceable pen tip for both passive and active capacitive pens. Background Technology

[0002] The pen tip is the key component that contacts the screen of the writing device. It is usually made of conductive materials, such as conductive rubber or conductive film. In active capacitive pens, it can accurately transmit electrical signals to achieve high-precision writing. In passive capacitive pens, it can simulate human touch operation. A good pen tip writes smoothly, is wear-resistant and durable, and some are even replaceable to adapt to different types of capacitive pens and usage scenarios.

[0003] Most existing pen tips can only be used on passive pens and cannot be replaced on active pen tips. They also tend to loosen and fall off during use on passive capacitive pens, and poor contact is common in the contact conduction process. Furthermore, they are inconvenient to disassemble and assemble. Therefore, those skilled in the art have provided a universal, multi-functional, replaceable pen tip for both passive and active capacitive pens to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a universal, multi-functional, replaceable pen tip for both passive and active capacitive pens. This pen tip can be directly used with both active and passive capacitive pens, and can be used simply by replacing the active pen tip. Furthermore, when the active capacitive pen is without power, it achieves conductivity by connecting to the internal structure of the active pen, thereby enabling contact conduction and communication between the device and the pen.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A universal, multi-functional, replaceable pen tip for both passive and active capacitive pen includes a pen tip and a disc. The pen tip has internal threads on one side and conductive adhesive on the other side. A conductive film is disposed on one side of the disc.

[0007] Furthermore, the threaded teeth match the threads of the capacitive pen body.

[0008] Furthermore, the pen tip serves as the first connecting and fixing component, allowing the conductive adhesive to contact the internal structure of the pen and effectively fix and conduct electricity, thereby enabling communication between the device and the pen.

[0009] Furthermore, the disk serves as a second connecting and fixing member, enabling the conduction of the conductive film and the conductive adhesive.

[0010] Furthermore, the conductive film is in direct contact with the device on its end face.

[0011] Furthermore, the conductive adhesive makes contact with and connects to the internal structure of the pen.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model proposes a universal, multi-functional, replaceable pen tip for both passive and active capacitive pens. This pen tip can be directly adapted to both active and passive capacitive pens without requiring complex modifications or additional devices to the capacitive pen. Users can quickly put it into use simply by replacing the active pen tip. This feature allows users to easily switch between different types of capacitive pens to meet their usage needs, greatly improving the convenience of use. Furthermore, when the active capacitive pen is out of power, the pen tip can still connect to the internal structure of the active pen to achieve conductivity. Through contact conduction, the device and the pen can connect and communicate, ensuring that writing or operation will not be interrupted even when the power is insufficient, thus guaranteeing the continuity of work or creation.

[0014] 2. This utility model proposes a universal, multi-functional, replaceable pen tip for both passive and active capacitive pen types. In this pen tip, the pen tip serves as the first connecting and fixing component, ensuring close contact and effective fixation of the conductive adhesive with the internal structure of the pen. The disc serves as the second connecting and fixing component, enabling stable conduction between the conductive film and the conductive adhesive. The conductive film possesses excellent conductivity and wear resistance, accurately sensing and transmitting touch signals. Furthermore, the conductive film and disc, which are the parts in contact with the device, can be replaced with various conductive materials and shapes, not only meeting different design requirements but also adapting to various usage scenarios, providing users with more choices.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figure 1-5 This utility model provides an embodiment of a universal multi-functional replaceable pen tip for both passive and active capacitive pens, including a pen tip 2 and a disc 3. The pen tip 2 has a threaded tooth 1 inside one side, which matches the thread of the capacitive pen body. The pen tip 2 serves as a first connecting and fixing component, allowing the conductive adhesive 5 to contact and effectively fix and conduct electricity with the internal structure of the pen, thereby realizing the communication between the device and the pen. The disc 3 serves as a second connecting and fixing component, enabling the conductive film 4 to conduct electricity with the conductive adhesive 5.

[0024] Specifically, the pen tip 2 is an important component of the entire replaceable pen tip. The internal thread 1 on one side of the pen tip precisely matches the thread of the capacitive pen body. This design allows the pen tip to be firmly installed on the capacitive pen body, and it can also be easily and quickly disassembled when the pen tip needs to be replaced. After the pen tip is installed on the capacitive pen body, the pen tip 2, as the first connecting component, uses conductive adhesive 5 on the other side of the pen tip 2. This adhesive has good conductivity and adhesion. On the one hand, it makes close contact with the internal structure of the pen, which can stably receive the electrical signals generated by the internal circuit of the pen. On the other hand, the conductive adhesive 5 is firmly held in a specific position by the fixing effect of the pen tip 2, which ensures the stability and reliability of the electrical signal transmission. In this way, an effective electrical connection is achieved between the internal structure of the pen and the pen tip, laying the foundation for information interaction between the device and the pen. In addition to the above-mentioned function of establishing the internal structure through the contact of the main signal component of the pen tip to achieve the writing function, the contact component can also be changed to conduct through the contact of the secondary signal or GND signal with the pen barrel, which can also achieve the writing function.

[0025] Reference Figure 3 The pen tip 2 has a conductive adhesive 5 inside on the other side, and a conductive film 4 is provided on one side of the disc 3. The conductive film 4 is on the end face and is in direct contact with the device. The conductive adhesive 5 is in contact with the internal structure of the pen and is connected to conduction.

[0026] Specifically, the disc 3, as the second connecting and fixing component, plays a crucial role in connecting the conductive film 4 and the conductive adhesive 5. The conductive film 4, located on one side of the disc 3, is positioned at its end face. When the capacitive pen is used on the device, the conductive film 4 directly contacts the device's touchscreen. The conductive film 4 has excellent conductivity and wear resistance, enabling it to accurately sense and transmit touch signals. After the conductive adhesive 5 contacts and connects with the internal structure of the pen, it transmits the electrical signals from inside the pen to the conductive film 4. Thus, through capacitive sensing or signal interaction between the conductive film 4 and the device's touchscreen, writing, drawing, or other operations can be achieved. Furthermore, the conductive film 4 and the disc 3, which are in contact with the device, can be replaced with various conductive materials and shapes to meet different design and usage requirements. The replaceable pen tip comes in two different shapes: flat-bottomed and round.

[0027] Working Principle: When using this universal multi-functional replaceable pen tip for both passive and active capacitive pens, the pen tip 2 is first installed onto the pen body via the thread 1. The internal circuitry of the pen generates electrical signals, which are conducted to the conductive adhesive 5 through contact. Due to the connecting and fixing effect of the disc 3, the conductive adhesive 5 transmits the received electrical signals to the conductive film 4. For passive capacitive pens, when the conductive film 4 contacts the device's touchscreen, it changes the capacitance distribution on the touchscreen surface. After detecting this capacitance change, the touchscreen can determine the touch position, thereby achieving the corresponding operation. For active capacitive pens, the internal circuitry of the pen... The circuit generates specific electrical signals, which are transmitted to the touchscreen through conductive adhesive 5 and conductive film 4. The touchscreen recognizes these specific signals, thereby enabling more precise operation. When the active capacitive pen runs out of power, the pen tip can still connect to the internal structure of the pen to maintain the connection and dialogue between the device and the pen through contact conduction. When the pen tip is worn or needs to be replaced with a different type of pen tip, simply unscrew the pen tip 2 from the capacitive pen body and replace it with a new pen tip. This makes pen tip replacement convenient and quick, meeting different usage needs. Users can choose to use a flat-bottomed or round pen tip according to their own writing habits and actual needs.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
