Stylus structure

The present invention relates to a stylus structure, and more particularly to a stylus structure for controlling a capacitive touch screen.

The touch screen is divided into five types: Resistive, Capacitive, Surface Acoustic Wave, Optics, and Electromagnetic. The resistive touch panel is mainly composed of a combination of two upper and lower ITO conductive layers. When used, the upper and lower electrodes are turned on by using pressure, and the position of the contact point is calculated by detecting the change of the panel voltage through the controller. The capacitive touch panel detects the coordinates of the capacitance (induced current) generated by the electrostatic combination between the arranged transparent electrodes and the human body.

Because Apple introduced mobile electronic products such as iPhone and iPod, and uses capacitive touch screens, in addition to its beautiful appearance and simple and flexible operation interface, the above products attract consumers with low reflection, high contrast and durability. Supports functions such as multi-touch and gesture operation (Gesture). The change in capacitance caused by the electrostatic reaction between the electric field between the finger and the touch screen can achieve the purpose of touching the capacitive touch screen, but it is difficult to accurately control the touch because the finger shields the user's line of sight. Point, and there is a problem with fingerprints or dirt remaining on the panel.

At present, there is a capacitive stylus using a combination of a pen tip and a disc, and the pen has 10,000 Designed to the ball of the connector, the angle of the pen can be changed at any time to be close to the touch screen. However, the foregoing technical means has no buffer design and is easy to damage the touch screen or the stylus, and the manipulation still has a smooth feeling. In addition, there is another stylus on the market that is connected to the touch portion by a spring, although the design improves the aforementioned problems. However, for the case of controlling the software system screen or the small button of the illustration, the problem that the offset is generated and the manipulation is not accurate is generated.

In view of this, the creator has made great efforts to solve the above problems by focusing on the above-mentioned prior art, and has devoted himself to the application of the theory, that is, the goal of the creator's improvement.

The main purpose of this creation is to provide a stylus structure that is more precise and smoother to control the touch screen.

To achieve the above objectives, the present invention provides a stylus structure for manipulating a touch screen. The stylus structure includes a grip portion, a auxiliary contact portion and an elastic connecting member. The grip is connected to a conductive refill. The auxiliary contact portion includes a conductive ring, a positioning unit is disposed on the conductive ring, and a through hole is formed. One end of the elastic connecting member is connected to the conductive pen core, and the other end is connected to the conductive ring through the positioning unit. The conductive pen core is formed inside the elastic connecting member and can interfere with the touch screen.

Preferably, the positioning unit comprises an annular channel or a plurality of positioning cylinders protruding from the surface of the conductive ring. The annular channel is formed on a periphery of an inner side wall of the positioning unit or a periphery of an outer side wall for locking one end of the elastic connecting member. Each positioning cylinder is further provided with a missing slot for securing one end of the elastic connecting member.

The detailed description and technical content of the present invention are described below with reference to the drawings, but the drawings are only for reference and explanation, and are not intended to limit the creation.

As shown in FIG. 1 to FIG. 4, the present invention provides a stylus structure 100 for controlling a capacitor. Touch screen 700 (shown in Figure 2). The capacitive touch screen 700 described herein includes, but is not limited to, a smart phone, a tablet, or the like. The stylus structure 100 includes a grip portion 200, a auxiliary contact portion 300, and an elastic connecting member 500. The grip portion 200 is connected to a conductive refill 210. The auxiliary contact portion 300 includes a conductive ring 302, a positioning unit 400 is disposed on the conductive ring 302, and a through hole 310 is formed. The conductive refill 210 is formed inside the elastic connector 500 and is capable of resisting the touch screen 700. In this embodiment, the conductive ring 302 includes, but is not limited to, a transparent ring to which a conductive film (not shown) is attached or a copper or other suitable metal material which is a smooth surface. In general, the outer diameter of the conductive ring 302 is about 8 mm, and the diameter of the through hole 310 is about 4 mm, but not limited thereto.

Further, the elastic connecting member 500 is preferably a coil spring, and is made of silver, copper, aluminum, or an alloy thereof having good electrical conductivity. As shown in FIG. 3 and FIG. 4, one end of the elastic connecting member 500 is an involute conical spiral 510 connected to the conductive ring 302 of the auxiliary contact portion 300, and the other end is connected to a cylindrical spiral 520 to connect one end of the conductive refill 210. . The involute conical spiral 510 described herein means that each turn of the spiral is not in close contact with the cylindrical spiral 520, but is a spiral pattern in which the interval is gradually increased, but the angle of the involute is not in question. When the user applies a small force, the conical spiral 510 can move the auxiliary contact portion 300, and at the same time has the effect of causing the auxiliary contact portion 300 to rebound. Therefore, when the conductive pen core 210 passes through the through hole 310 of the auxiliary contact portion 300 to interfere with the touch screen 700, the elastic connecting member 500 has better elastic flexibility, so that the elastic connecting member 500 can be flexibly The conductive pen reed 210 moves.

In the embodiment shown in FIG. 3 and FIG. 4 , the grip portion 200 further includes a conductive sleeve 220 and a grip slot 230 . The conductive sleeve 220 is sleeved at one end of the conductive pen core 210, and one end of the elastic connecting member 500 (ie, the cylindrical spiral 520) is positioned on the conductive sleeve 220. by The conductive refill 210 is made of a soft material, such as conductive fiber, conductive rubber or other suitable material, so that the conductive sleeve 220 is sheathed to prevent the conductive refill 210 from being damaged. As shown in FIG. 4, since the diameter of one end of the conductive sleeve 220 is equal to the inner diameter of the stem slot 230, and the elastic connecting member 500, the conductive sleeve 220 and the conductive lead 210 are stacked on each other, the diameter is substantially the same. The inner diameter of the grip slot 230 is thus assembled and received in the grip slot 230.

In this embodiment, the conductive refill 210 further includes a first section 212 and a second section 214. The diameter of the second section 214 is greater than the diameter of the first section 212, wherein the second section 214 is partially Exposed to the outside of the grip portion 200, the first section 212 is sleeved by the conductive sleeve 220. The conductive sleeve 220 is substantially positioned between the first section 212 and the second section 214 such that the conductive sleeve 220 does not move further toward the second section 214, thus the elastic connection fixed to the conductive sleeve 220 The cylindrical spiral 520 of the member 500 is also not easily displaced toward the auxiliary contact portion 300 on the conductive sleeve 220. In addition, the cylindrical spiral 520 and the conical spiral 510 of the elastic connecting member 500 in this embodiment are substantially separated from the second section 214 and the first section 212.

The following describes further how the elastic connecting member 500 connects the auxiliary contact portion 300 by the positioning unit 400. As shown in FIG. 5, the positioning unit 400 further includes an annular channel 320 formed on the periphery of an outer side wall 306 of the positioning unit 400 for locking one end of the elastic connecting member 500 (ie, the conical spiral 510). . However, in the embodiment shown in FIG. 6, the annular channel 320 may also be formed at a periphery of an inner sidewall 304 of the positioning unit 400. In the embodiment of FIG. 5 and FIG. 6, the size of the annular channel 320 is preferably greater than or equal to the helical diameter of the elastic connecting member 500, and is positioned in the annular channel 320 by the spring rigidity of the elastic connecting member 500 itself. .

Therefore, when the conductive ring 302 of the auxiliary contact portion 300 contacts the touch screen (not shown), the conductive ring is electrically conductive. The refill 210 will pass through the perforation 310 of the auxiliary contact portion 300 to resist the touch screen 700, and the conductive ring 302 will smoothly sway and move following the movement of the conductive refill 210. That is to say, the auxiliary contact portion 300 first contacts the touch screen and provides an approximate target point of the manipulation target, and the conductive refill 210 will more accurately indicate the point/object of the manipulation target, and finally touch the conductive ring 302. Electronic signals are formed on the screen to form coordinates. Therefore, regardless of whether the software system screen or the button is small, the stylus structure 100 of the present invention can accurately and smoothly control the touch screen (not shown).

In order to align the target points more accurately and quickly, the conductive ring 302 further includes a slanted annulus 312, as shown in FIG. The inclined annular surface 312 is disposed on the inner wall of the through hole 310, and the through hole 310 forms a first inner diameter d and a second inner diameter D. The first inner diameter d is smaller than the second inner diameter D, and the first inner diameter d is disposed farther from the grip portion 200 than the second inner diameter D, wherein the size of the first inner diameter d is slightly larger than the outer diameter of the conductive refill 210 The conductive pen core 210 can be passed through the first inner diameter d. Since the perforations 310 of the conductive ring 302 are smaller in size than the previous embodiment, the displacement of the conductive ring 302 relative to the conductive refill 210 is relatively small, and thus the conductive refill 210 can quickly and accurately align the target points. In addition, the inclined annulus 312 of the conductive ring 302 (90 degrees, but not limited) also has the effect of guiding the alignment of the conductive refill 210.

As shown in FIG. 8 and FIG. 9, the exploded view and the combined partial perspective view of the present elastic connecting member and the positioning unit (third embodiment) are shown. The positioning unit 400 further includes a plurality of positioning cylinders 330 protruding from the surface of the conductive ring 302. Each of the positioning cylinders 330 is further provided with a notch 332 for locking one end of the elastic connecting member 500. In the present embodiment, the positioning unit 400 is preferably three positioning cylinders 330. However, in another embodiment, the two positioning cylinders 330 can achieve the same effect. Similarly, after the conductive ring 302 of the auxiliary contact 300 contacts the touch screen (not shown), the conductive refill 210 passes through the through hole 310. In opposition to the touch screen 700, the conductive ring 302 smoothly oscillates and moves following the movement of the conductive refill 210. This is a smooth and precise way to complete a variety of buttons or small touch screens.

The embodiments disclosed herein are to be considered as illustrative of the present invention and are not intended to limit the present invention. The scope of this creation is defined by the scope of the appended patent application and covers its legal equivalents and is not limited to the foregoing description.
