Description

Multifunctional emulation capacitive pen

technical field

The utility model relates to the field of intelligent electronic equipment, in particular to a pen specially operated on a capacitive touch screen, specifically a multi-functional emulation capacitive pen which is portable, easy to replace the pen tip and has a wide application range.

Background technique

The control screen works by using the current induction of the human body. It is a four-layer composite glass screen. The inner surface and the interlayer of the glass screen are each coated with a layer of ITO (coated conductive glass), and the outermost layer is a thin layer of silica glass protective layer. The ITO coating is used as the working surface, four electrodes are drawn from the four corners, and the inner layer of ITO is the shielding layer to ensure a good working environment. When the finger touches the metal layer, due to the electric field of the human body, the user and the surface of the touch screen form a coupling capacitance, for high-frequency current, the capacitance is a direct conductor, so the finger absorbs a very small current from the contact point. This current flows out of the electrodes on the four corners of the touch screen respectively, and the current flowing through these four electrodes is proportional to the distance from the finger to the four corners. The controller obtains the touch point by accurately calculating the four current ratios. location information.

With the proliferation of smart capacitive screen touch phones, tablet PCs, desktop computer all-in-ones, and smart TVs, covering the world, the demand for touch screens has increased, and accessories have also become popular. The market potential is huge. The emergence of capacitive pens is for better Inputting mobile phones and tablet computers, users do not need to operate with fingers for a long time, avoiding the fatigue caused by long hours of entertainment and work. For example, many people use it for drawing, and if they touch it with their fingers for a long time, there will be many shortcomings. Fatigue, inaccurate touch, thick fingers, sweating, etc. will affect touch writing. The emergence of capacitive stylus has just solved this problem. The capacitive stylus is a pen made of conductive material with conductive properties, which is used to touch the capacitive screen to complete the man-machine dialogue operation. Used to touch electronic devices such as mobile phones, game consoles, and computers with capacitive touch screens. The use of a capacitive pen can reduce bacterial cross-infection from hands to the screen, and it can also avoid the trouble of cleaning the screen due to fingerprints and sweat stains that are easy to be left by finger operation, and it can also bring a better experience.

The principle of capacitive touch is that when a finger or other conductive material touches the panel, the panel will detect the capacitance change on the surface and generate an electronic signal to determine the touch position. Therefore, you can use your fingers or other conductive materials to control; while the traditional plastic resistive stylus and other non-conductive materials cannot be controlled. Capacitive touch pens currently on the market mainly use conductive materials such as conductive cotton, rubber (coated with conductive paint on the surface), and conductive fibers. The principle is to use conductive materials on the surface. Although the principle is simple, in fact, traditional capacitive pens are prone to broken strokes and insensitivity. Worse than fingers. The sensitivity of the capacitive screen is very high, it can precisely locate the position of the pen tip, and can write characters of the same size as we usually write, and simultaneously draw the width and stroke of the handwriting corresponding to different pressure values on the display screen, and its writing effect is almost equivalent to Pen and paper writing. Theoretical accuracy can reach 1-2mm, but due to the thick tip of the finger or capacitive pen, it is not easy to accurately locate within the range of 1-2mm in practice, because the sensing accuracy of the capacitive screen to the finger and the capacitive pen with a thick pen tip is not high, so in Capacitive screens are not easy to write smaller fonts. The capacitive screen also has no pressure sensing function, so it cannot form original handwriting. And the traditional capacitive pen is mainly composed of a metal pen holder and conductive silica gel. The capacitive pens on the market are relatively short and have a bad hand feel, which is not suitable for long-term writing. Because the traditional capacitive pen mostly simulates the touch of the finger pulp and uses a hemispherical pen tip, the pen tip of the general capacitive pen is thicker and the pen tip is relatively single. When writing, the pen tip is too large to look directly at the movement track of the pen tip, and the handwriting is relatively rough. not tall.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

As shown in Figure 1-15: a multi-functional simulation capacitive pen, including a pen body 1 and a pen head 11, the pen body 1 can be made into a retractable pen body according to needs, so as to reduce the overall length and volume of the capacitive pen Easy to carry, the nib 11 includes a nib 10, a metal hoop 9 and a connecting rod 8, the nib 10 is fixed on one end of the connecting rod 8 through the metal hoop 9, and the connecting rod 8 is magnetically attracted to the lower part of the pen body 1 so that the connecting rod 8 is inserted into the pen The lower part of the pen body 1 is fixed in the cavity; in order to prevent the nib from rotating and slipping during use, the lower part of the pen body 1 is provided with an open slot 4, which is used to accommodate the corresponding protruding block 41 on the connecting rod 8, The protruding pieces 41 and the opening grooves 4 are engaged with each other, and the opening grooves 4 and the protruding pieces 41 are generally arranged in pairs of two or more. Specifically, the fixing method of the connecting rod 8 of the above-mentioned simplified version of the capacitive pen is realized in the following manner: the connecting rod 8 itself has magnetism and the lower part of the pen body 1 is provided with a metal that can be attracted to the magnetism. The mutual attraction between the rod 8 and the pen body 1 plays a fixed role and facilitates the quick replacement of the pen head 11; it solves the problem of the traditional use of capacitive pens with serpentine spirals for rotating installation, the installation place is relatively thin and easy to crack, and the installation is cumbersome and the overall pen body A rougher question.

In addition, for the capacitive pen to automatically adjust the size of the force during use, improve the writing feel and protect the capacitive screen, an adjustment device is provided in the pen body 1, and the adjustment device includes the movable rod 5, the end of the movable rod 5 and the An upper limit piece 21 and a lower limit piece 31 are respectively arranged on the shaft and the other end of the movable rod 5 is provided with a first magnetic piece 6, and the upper limit piece 21 and the lower limit piece 31 are respectively located on the upper stopper 2 provided in the pen body 1. and the top of the lower blocking piece 3, and between the lower limiting piece 31 and the upper blocking piece 2, there is a spring 7 sleeved on the movable rod 5, and the movable rod 5 passes through the upper blocking piece 2 and the lower blocking piece 3 respectively. Make the first magnetic sheet 6 and the second magnetic sheet 61 at the end of the connecting rod 8 attract each other so as to fix the connecting rod 8. The first magnetic sheets 6 attract each other, which not only plays a role in fixing the nib 11, but also facilitates quick replacement of the nib 11.

In order to cooperate with the capacitive pen provided by the present invention, seven kinds of nibs 11 for different professional purposes are now designed. The shape of the nib 10 at the end of the nib 11 includes a tapered acicular made of silica gel coated with nano-silver, and a nib made of conductive silica gel. Hemispherical shape, pen tip shape made of conductive silicone, cylindrical shape made of silicone coated with nano-silver, hair shape made of conductive fiber material, art pen shape and water drop shape made of conductive silicone material.

The first type of nib 11 makes the nib 10 into a tapered needle shape (see accompanying drawings 6 and 9), and this kind of nib 10 can improve the viewing angle when writing, which is consistent with traditional writing. Since the capacitive screen has no pressure sensing function, it is impossible to freely draw the width and stroke of the handwriting corresponding to different pressure values. Therefore, the tapered needle-shaped nib 10 is divided into three layers, and the diameter of the bottom nib 10 is designed to be 1.2mm to 2.2mm (the theoretical accuracy of the capacitive screen can reach 1-2mm), which can minimize the width of the stroke; the middle layer The nib 10 of the upper layer has a diameter of 2.4 mm to 3.4 mm; the nib 10 of the upper layer has a diameter of 3.2 mm; the gap between the layers of the nib 10 is set at 0.5 mm to 1 mm. The material of the nib 10 is made of silicone with a soft surface coated with nano-silver (silver is a metal with excellent conductivity), and a transparent conductive coating is added to the nib 10 to increase the smoothness and durability of writing . When writing, because the writing force becomes stronger, the bottom nib 10 is upwards (silica gel is a soft and elastic material), and the middle layer and the upper nib 10 partly touch the capacitive screen downwards, thereby changing the contact area to the capacitive screen. Apply pressure to the nib 10, and reflect the change of the pressure of the nib 10 by changing the contact area between the nib 10 and the capacitive screen to form the original handwriting. Then can use the nib 11 of this capacitive pen to finish when needing quick record (as meeting record), original handwriting (as document signing and approval), precise operation (as painting). The width of the handwriting is controlled at 1.2 mm when writing without force, the width of the handwriting is controlled at 1.8 mm to 2.4 mm when writing with light force, and the width of the handwriting is controlled at 2.8 mm to 3.2 mm when writing with moderate force. If through the development and optimization of the software, the accuracy of writing can be further improved. The advantages of this kind of nib 11 are: the touch sensitivity of the capacitive screen is improved, the writing accuracy and smoothness are reduced, the diameter of the nib of the capacitive pen is reduced, and the viewing angle when writing is improved. Glue capacitive pens are made of this cheap material. The conductive adhesive is soft, but strong and durable. The silicone head has been specially treated, and a special coating that is invisible to the naked eye has been added. It is better than ordinary pens in fluency. The nib 11 is detachable. If an accident occurs in the nib 11, another nib 11 can be used again. The accuracy and sensitivity are appropriate. The touch sensitivity of the capacitive screen is improved, and the diameter of the tip 11 of the capacitive pen is reduced.

The second type of nib 11 is to make the nib 10 into a hemispherical shape (see accompanying drawing 10), which mainly simulates the tactile sensation of the finger pulp and improves the range of use angles, so the nib 10 is relatively thick, and the viewing angle is relatively small when writing, and the accuracy is not good. The font is tall and thick, and traditional capacitive pens mostly use this shape. For example, if the traditional hemispherical nib is changed to a drop-shaped nib (see Figure 15), the friction force will be reduced and the writing will be smoother, and the writing viewing angle will be greatly improved. The advantage of this type of nib 11 is that most of the materials are made of conductive silica gel, which is relatively cheap.

The third nib 11 is to make the nib 10 into a pen shape, and the nib 10 is a spherical body (seeing accompanying drawing 11 ) with a diameter of 1.2mm, and both sides are metal hoops 9 that connect the nib 10 to fix. The spherical body is made of durable and soft conductive silica gel, and the hardness of the joint part connected with the spherical body is increased. It is mainly suitable for small-size writing, geometric drawing, mechanical drawing, and operations where the relative line width is relatively thin and the line width does not change significantly. The advantage of this kind of nib 11 is: the contact area with capacitive screen can be controlled at about 1 plane millimeter minimum, and the width of handwriting is fixed about 1mm.

The fourth type of nib 11 is to make the nib 10 into a cylindrical shape with a diameter of 3 mm (see Figure 12), and use silica gel with moderate hardness and the surface is coated with nano-silver to make a frosted texture and create several random vertical pits. Fix it with a metal hoop 9; the middle of the written word naturally creates a hollow feeling, and the font is thicker, giving it the feeling of a watercolor pen. The advantage of this kind of nib 11 is: it is more suitable for children's graffiti and entertainment.

The 5th kind of nib 11 is that the nib 10 adopts straight conductive fiber material (like hair shape) to install according to the mode that the middle is long and both sides are short (see accompanying drawing 13), make a writing brush that can conduct electricity. Writing brush characters on the capacitive screen can be realized through the optimization of the software. The advantage of this kind of nib 11 is: the nib 10 is made of fiber material, which can automatically maintain a straight state and all the fibers move closer to the center. This material is less used in capacitive pens, but its fluency is much better than that of silica gel. It is easy to draw and write. Very delicate and smooth. the

The sixth type of nib 11 is designed to imitate the shape of the nib 10 of an art pen, that is, the nib 10 changes from thin to thick in diameter and from soft to hard from bottom to top, and keeps bending in the middle. This can be achieved by changing the writing angle, changing the width of the handwriting. Of course, it can also be made into a brush-type pen tip for painting oil paintings. It must be great to simulate painting oil paintings on the computer. Users can also make different pen tips or formulate them by themselves, because this is a capacitive pen that can replace different pen tips.

The above embodiments are only to illustrate the technical ideas of the utility model, and cannot limit the protection scope of the utility model with this. Any changes made on the basis of the technical solutions according to the technical ideas proposed by the utility model all fall into the scope of the utility model. Within the scope of protection of the new model; technologies not involved in the utility model can be realized by prior art.
