The detailed description of the present invention described below refers to the accompanying drawings, which show by way of example specific embodiments in which the present invention may be practiced. These embodiments are described in sufficient detail to enable those skilled in the art to practice the invention. It should be understood that the various embodiments of the invention are different from one another but are not necessarily mutually exclusive. For example, specific shapes, structures and characteristics described herein with respect to one embodiment may be implemented in other embodiments without departing from the spirit and scope of the invention. Additionally, it should be understood that the location or arrangement of individual components within each disclosed embodiment may be changed without departing from the spirit and scope of the invention. Accordingly, the detailed description that follows is not intended to be taken in a limiting sense, and the scope of the invention is limited only by the appended claims, together with all equivalents to what those claims assert, if properly described. Similar reference numbers in the drawings refer to identical or similar functions across various aspects.

Hereinafter, in order to enable those skilled in the art to easily practice the present invention, preferred embodiments of the present invention will be described in detail with reference to the attached drawings.

The present invention is a hybrid pen tip-related invention and has a more efficient structure. In addition, it is composed of a structure and material that can be used for analog writing objects (e.g. paper, wood, steel, etc., all materials on which pencils are written) and display panels, providing both pencil functions (analog writing instruments) and electronic pen functions (digital writing instruments). can be provided. Specific details related to this will be described below.

The electronic pen 10 of the present invention is not limited to a specific company, but may correspond to products from various companies (ex. Apple, Samsung, Wacom, etc.), and can be largely divided into a pen tip 100 and a main body 200.

In the case of a general pen tip 100, it is easily worn out as it is used in contact with an analog writing object, etc., and thus requires frequent replacement. However, in the case of the nib portion 110 of the pen tip 100 of the present invention, it is made of a carbon composite material containing carbon (C) such as graphite, and can have a structure that is not easily worn while being used as a pencil. It can be made of a kind of infinite pencil-like material.

In other words, existing pen tips are frequently replaced every cycle, but the pen tip 100 of the present invention can have a longer usage cycle than existing pencils.

In addition, since it does not wear out easily, the number of cases where writing feeling deteriorates or malfunctions of the electronic pen 10 occur can be reduced. For reference, the degree of wear may vary depending on the carbon (C) content (the higher the carbon content, the higher the wear speed, inversely proportional structure). The material composition of the pen nib portion 110 will be examined in more detail later with reference to FIG. 6.

In addition, as can be seen in Figure 2, the pen tip 100 and the main body 200 of the present invention can be separated, and the lower inner hole of the pen tip 100 and the upper protrusion 210 of the main body 200 can be combined. You can.

As we will see later, there is a screw groove around the lower inner hole of the pen tip 100, and a screw coupling part is present around the lower end of the protrusion 210 of the main body 200, so that the pen tip 100 is connected through screw coupling. and the main body 200 may be fixedly coupled to each other.

For reference, the screw coupling portion may be located at the bottom of the protrusion 210 and may be located inside the main body 200. That is, when the main body 200 and the pen tip 100 are coupled, the 2-3 parts (123, the part including the lower inner hole) of the pen tip 100 that are fixedly coupled to the screw coupling portion are connected to the main body ( 200), and only the 2-1 part 121, which will be described later, can be exposed to the outside.

Additionally, the 2-2 part 122 may also enter the interior of the main body 200. Parts 2-1 to 2-3 included in the pen tip 100 will be described later.

The main body 200 can generate an electrostatic signal that is different from a finger internally using an active electrostatic (AES) method, and can transmit the electrostatic signal to the pen tip 100 through the protrusion 210. there is. The display recognizes the strength and position of the signal generated at the tip of the pen tip 100, calculates the most accurate position, and displays it on the display.

Of course, the main body 200 may include a copper coil and a radio frequency (RF) generator using an electromagnetic resonance (EMR) method. At this time, when the display emits an electromagnetic field, electromagnetic induction occurs in the coil of the main body 200 and electromagnetic waves are emitted, and this can be recognized by the display to display the location of the signal, etc.

Ultimately, the electronic pen 10 of the present invention can consider both active electric (AES) and electromagnetic resonance (EMR). However, it will not be limited to this.

First, the pen tip 100 of the present invention can be divided into a nib portion 110 and a head portion 120. Specifically, the pen nib 110 is used as an analog writing instrument (ex. pencil) for analog writing objects (ex. paper, wood, metal, etc.), and as a digital writing instrument (ex. touch pen) for displays (panels). It can be used and can include carbon (C) as a component.

Since it is made of a graphite material containing carbon (C), etc., the pen tip 110 can also conduct electricity, and the static electricity signal received through the protrusion 210 of the main body 200 is transmitted to the display and indicates the position. It can be done. In addition, the pen nib portion 110 of the present invention is made of a carbon composite material as described above and may not be easily worn.

For reference, if the pen nib portion 110 is worn, the height may be different from that of the existing electronic pen, and the accuracy of electronic pen recognition may decrease. This is because there is a height of the electronic pen set for each specific company (e.g. Apple), and more accurate location, strength, etc. can be recognized only when it touches the display according to that height.

In addition, the pen tip 100 surrounds the pen tip 110 so that the end of the pen tip 110 is exposed to the outside, and has a head 120 including a groove therein to enable coupling with the main body 200. may include.

As can be seen in FIG. 3, the head portion 120 surrounds the pen nib portion 110 so that the remaining portion except for the end portion is not exposed to the outside.

The pen tip portion 110 is not completely fixed, and may be fixed so that it only moves up and down under pressure and does not move left or right. For reference, it may be advantageous for the user's writing experience to structure the pen nib 110 so that it moves slightly up and down rather than being completely fixed. Although it is described above as moving, the actual degree of movement is subtle and may be difficult to see with the naked eye.

Also, referring to FIG. 3, the head portion 120 includes at least three parts in the longitudinal direction, and the three parts are a 2-1 part 121 and a 2-2 part 122 from the top. , can be divided into 2-3 parts (123).

The cross-section of the 2-1 part 121 has a trapezoidal shape with the top narrower than the bottom, and may be structured in the shape of a truncated cone with a flat top. Unlike the

other parts

122 and 123, the 2-1 part 121 can be located outside even when the pen tip 100 and the main body 200 are combined.

In addition, the radius of the 2-2 part 122 among the 2-1 part 121, the 2-2 part 122, and the 2-3 part 123 based on the center line of the head 120 This may be the shortest. This is because, except for the 2-1 part 121, the 2-2 part 122 and the 2-3 part 123 are located inside and are not exposed to the outside when combined with the main body 200. am.

In addition, in the case of the 2-3 part 123, since there is a screw groove inside and can be screwed and fixed to the protrusion 210 of the main body 200, the radius of the 2-2 part 122 , that is, the width may be the smallest.

Additionally, the height of the 2-1 part 121 may be longer than the height of the 2-2 part 122 and the height of the 2-3 part 123. Additionally, the height of the 2-3 part 123 may also be longer than the height of the 2-2 part 122 in order to be combined with the protrusion 210 of the main body 200 while contacting it in a large area. That is, the height of the 2-2 part 122 may be the shortest.

Additionally, referring to FIG. 3, the inner hole of the 2-1 part 121 and the inner hole of the 2-2 part 122 are connected and may match the width of the protrusion 210. This is to create a passage so that the protrusion 210 of the main body 200 can easily move and contact the lower side of the pen tip 110.

There is a screw groove located inside the 2-3 part 123 at the bottom of the 2-1 part 121 and the 2-2 part 122, and the width of the screw groove based on the center ( The horizontal width may be longer than the width (width) of the inner hole of the 2-1 part 121 formed for movement of the protrusion 210 or the width (width) of the inner hole of the 2-2 part 122. there is.

For reference, the head 120 may be made of a material that does not conduct electricity (e.g. plastic, etc.). If electricity is applied to the head 120 rather than the pen tip 110, static electricity transmitted from the main body 200 may also be transmitted to the head 120, making it difficult to determine the exact location of contact with the display. Because you can lose.

The pen tip portion 110 may include at least three parts in the longitudinal direction, and the at least three parts include a 1-1 part 111 located at the top and in contact with paper or a display, and the 1st- It can be divided into a 1-2 part 112 located at the bottom of the 1 part 111, and a 1-3 part 113 located at the bottom of the 1-2 part 112. That is, the 1st-3rd parts 113 are located at the bottom of the pen nib portion 110.

For reference, the plurality of

parts

111, 112, and 113 included in the pen nib portion 110 may all be made of graphite or carbon composite material containing carbon and may conduct electricity. In some cases, the pen nib portion 110 of the present invention may not contain carbon (C) but may contain a material that conducts electricity and allows writing on an analog writing object (such as paper).

Here, the cross-sectional area of the top of the 1-1 part 111 may correspond to a semicircle, and the cross-sectional area below the middle of the 1-1 part may correspond to a square. That is, the 1-1 part 111 has a hemispherical shape located on a cylindrical shape, and this is to facilitate the user's writing feeling by making smooth contact with paper or a display due to the hemispherical shape.

In the drawing, the cross-sectional area of the upper part of the 1-1 part 111 is shown as a semicircle (hemispherical shape), but it is not limited to this, and it can help the writing feeling by making smooth contact with an analog writing object (paper) or display, etc. Any shape can be included in the present invention.

In addition, according to an embodiment of the present invention, the radius of the cylinder of the 1-2 part 112 is greater than the radius of the cylinder of the 1-1 part 111 based on the center line of the pen nib portion 110. It can be long. In the cross-sectional area, the outline shape extending between the 1-1 part 111 and the 1-2 part 112 may form an 'ㄴ' shape.

This prevents the pen tip 110 from moving up and down inside the head 120 but not completely leaving the head 120, that is, the 1-2 part 112 moves up and down inside the head 120. This is to prevent it from being caught. The pressure applied from the pen tip to the center of the electronic pen 10 according to the pen pressure facilitates contact between the pen tip 100 and the main body 200. Conversely, when no pen pressure is applied, the pen tip 110 moves toward the head. It can be prevented from moving away from (120).

In addition, in a state where the head 120 and the main body 200 are separated, the pen nib 110 is inserted from the lower side of the head 120 and positioned so that the tip is exposed outside the upper side of the head 120. can do. At this time, the radius of the 1-1 part 111 of the pen nib 110 is the same as or smaller than the radius of the upper hole of the head 120, so that it can pass through and be exposed to the outside, but the 1-1 part 111 of the pen nib 110 may be exposed to the outside. Part 2 112 does not pass through the upper hole of the head 120 and becomes stuck. That is, the 'ㄴ' shape of the pen nib 110 is such that when the pen nib 110 is inserted from the lower side of the head 120 (when assembling the head and the main body), the head 120 It is something that can help you get stuck without being able to escape completely. For reference, it may be inserted and coupled like this, but in some cases, it may be injected with the pen tip portion 110 included.

Unlike the above, according to another embodiment of the present invention, the radius of the cylinder of the 1-2 part 112 may be smaller than or equal to the radius of the cylinder of the 1-1 part 111. That is, the outline shape extending between the 1-1 part 111 and the 1-2 part 112 in the cross-sectional area may form a structure other than the 'ㄴ' shape. This is because any structure is possible as the structure of the present invention, as long as it corresponds to a hybrid pen tip that performs a pencil function and an electronic pen function.

Meanwhile, the radius of the upper part of the 1-3 part 113 is the same as the radius of the 1-2 part 112, and the radius decreases toward the lower part of the 1-3 part 113, -3 Part 113 may correspond to a structure that becomes narrower in the downward direction.

Here, as can be seen in FIG. 4, the 1-3 part 113 is a structure that continues from the 1-2 part 112, and the width becomes narrower in the downward direction, forming a cone shape that is sharp in the downward direction. It can be achieved.

In addition, the first-third part 113 of the present invention is not limited to the cone shape, but can have any shape as long as it has a structure that narrows downward, such as a step shape that narrows downward, a parabolic shape with a convex bottom, etc. can do.

As above, the reason why the first to third parts 113 have a structure that becomes narrower in the downward direction will be examined together with FIG. 5.

First, the upper surface of the protrusion 210 of the main body 200 may be divided into a first area 211 through which static electricity signals are transmitted and a second area 212 surrounding it. When the 1-3 part 113, which is the lowermost part of the pen tip 110, and the first area 211 come into contact, an electrostatic signal is transmitted to the pen tip 110 and the position on the display is also accurately recognized. It can be.

Since the first area 211 to which the electrostatic signal is transmitted is located in the center of the upper surface of the protrusion 210, the first to third parts 113 of the pen nib 110 also have a second area 212 around the periphery. It needs to be structured to facilitate contact with the first area 211 in the central part. Accordingly, the 1-3 part 113 forms a structure that becomes narrower in a downward direction, so that contact with the first area 211 can be facilitated.

In particular, when the 1-3 part forms a conical structure according to an embodiment of the present invention, the vertex portion (the lowest end of the 1-3 part) contacts the protrusion 210 of the above-described main body 200. may be, and accordingly, the electrostatic signal generated in the main body 200 may be transmitted to the 1-1 part 111 through the 1-3 part 113.

Meanwhile, in some cases, the lowermost end of the first-third part 113 may not have a structure that narrows downward, but may have a flat shape with a small area.

That is, the first to third parts 113 may have the same width rather than a structure that narrows downward. Specifically, it may correspond to a pillar shape (ex. cylinder, prism, etc.) that has a width smaller than the width of the first-second part 112 and continues with the same width up and down. Additionally, a case where the width is equal to the width of the first-second part 112 may also be considered.

As described above, the first to third parts 113 of the present invention have a structure that does not break easily (e.g., a structure that becomes narrower in the downward direction), and because they are made of a carbon composite material, a stronger structure can be formed. there is.

According to one embodiment of the present invention, the pen nib portion 110 may be made of a carbon composite material containing carbon (C). As a carbon composite material containing carbon (C), the component ratio may vary.

For example, as shown in Figure 6(a), the carbon (C) content is 86.99%, but it may also be composed of 10.11% oxygen (O) and 0.55% sodium (Na), etc., as shown in Figure 6(b). As can be seen, the carbon (C) content is 99.38%, but it can also be composed of 0.30% sodium (Na), 0.12% chlorine (Cl), etc.

In addition, referring to Figure 6(c), the pen nib portion 110 of the present invention contains 64.15% carbon (C), 25.19% oxygen (O), 3.10% chlorine (Cl), and 2.99% sodium (Na). It may be configured.

The component ratios indicated in the drawings are merely examples, and similarly, the pen nib portion 110 of the present invention may contain components other than carbon (C).

In the above, the present invention has been described with specific details such as specific components and limited embodiments and drawings, but this is only provided to facilitate a more general understanding of the present invention, and the present invention is not limited to the above embodiments. , a person skilled in the art to which the present invention pertains can make various modifications and variations from this description.

Therefore, the spirit of the present invention should not be limited to the above-described embodiments, and the scope of the patent claims described below as well as all modifications equivalent to or equivalent to the scope of the claims fall within the scope of the spirit of the present invention. They will say they do it.
