Description

Stylus

The present invention relates to a pen, in particular to a touch pen.

Touch screens have a place in modern life, such as smart phones, tablet computers, electronic drawing boards, electronic whiteboards, etc. In addition to some devices that can be operated directly by hand, most of the time, touch screens must be operated with a stylus. Currently, the stylus on the market can be divided into two types according to the application field, namely capacitive stylus with capacitance sensing ability and infrared stylus with infrared technology. Whether it is a capacitive stylus or an infrared stylus, the user's grip, comfort, durability and appropriate writing feel must be considered.

In order to achieve the above effects, the existing stylus pen tips can be divided into two categories: hard and soft. The hard pen tip can reduce the overall volume and have a sharpness, but when writing, the hard pen tip is likely to make a loud sound when it contacts the touch screen surface. Although the soft pen tip can reduce the volume during use, if it is to take into account the conductivity, most of them use a structure of silicone plus conductive cloth, which makes the overall volume unable to be reduced and cannot have a sharpness.

Therefore, one of the objects of the present invention is to provide a touch pen that can solve any of the above-mentioned deficiencies.

Therefore, the touch pen of the present invention is suitable for contacting a touch screen, and includes a pen body, a pen mouth, a pen head and a buffer. The pen mouth is arranged at one end of the pen body and defines a receiving space. The pen mouth has an opening portion connected to the receiving space. The pen head is arranged in the receiving space and penetrates the opening portion. The pen head includes an insertion section arranged in the receiving space, and a writing section connected to the insertion section and penetrates the opening portion. The writing section is used to contact the touch screen. The pen tip can be switched between an unused position and a used position relative to the pen mouth. When the pen tip is in the unused position, the writing section contacts the touch screen to move the pen tip toward the pen body, thereby switching the pen tip from the unused position to the used position. The buffer is connected to the pen tip and can be compressed and deformed when the pen tip is in the used position.

In some embodiments, a supporting platform is further included on the pen tip, and when the pen tip is in the use position, the insertion section abuts against the supporting platform.

In some embodiments, two ends of the buffer are respectively connected to the support platform and the insertion section, and when the pen tip is in the use position, the insertion section and the support platform jointly compress the buffer.

In some embodiments, the buffer is disposed between the writing section and the opening, and when the pen tip is in the use position, the writing section and the opening jointly compress the buffer.

In some embodiments, the pen tip has a groove located in the accommodating space and connected to the opening portion, the buffer member has a first buffer portion arranged in the groove, and a second buffer portion arranged in the opening portion, the insertion section of the pen tip is inserted in the first buffer portion, and is arranged in the accommodating space together with the first buffer portion, when the pen tip is in the use position, the writing section compresses the second buffer portion, and the insertion section compresses the first buffer portion.

In some embodiments, the pen tip further has a smooth layer located outside the writing segment.

In some implementations, the buffer is a soft material or a spring.

In some implementations, the buffer has electrical conductivity.

Therefore, another object of the present invention is to provide a touch pen that can solve any of the above-mentioned deficiencies.

Therefore, the touch pen of the present invention is suitable for contacting a touch screen, and comprises a pen body, a pen mouth and a pen head. The pen mouth is arranged at one end of the pen body and has an opening. The pen head is connected to the opening and is used to contact the touch screen. The pen head is a soft material with conductive ability and includes a writing section for contacting the touch screen.

In some embodiments, the nib further includes a smooth layer outside the writing segment.

In some implementations, the writing segment also has a texture structure.

In some embodiments, the diameter of the nib is no greater than 6 mm.

The effect of the present invention is that the touch pen is connected to the pen tip through the buffer, or the pen tip is made of the soft material with conductive ability, so that the touch pen can buffer the impact force of the pen tip when writing, thereby reducing the sound emitted. Moreover, when the pen tip is made of the soft material, it can also have conductive ability to improve the existing touch pen that emits a loud sound when used and cannot have both soft pen tip and capacitor quality induction.

Before the present invention is described in detail, it should be noted that similar components are represented by the same reference numerals in the following description.

Referring to FIGS. 1 to 3 , a first embodiment of a touch pen 100 of the present invention is suitable for contacting a touch screen (not shown), such as a smart phone, a tablet computer, an electronic drawing board, an electronic whiteboard, etc. The touch pen 100 includes a pen body 1, a pen nozzle 2, a support platform 3, a pen head 4 and a buffer 5.

The pen body 1 is in the shape of a long strip and is used for the user to hold. However, the appearance and internal design of the pen body 1 are not the focus of this patent specification, so the details are not described in detail here.

The nib 2 is disposed at one end of the pen body 1 and is in a funnel-like hollow shape. The nib 2 defines a receiving space 21 and has an opening 22 connected to the receiving space 21 and located at a side away from the pen body 1 . The opening 22 is formed with a through hole 221 .

The supporting platform 3 is disposed in the nib 2 , and more specifically, the supporting platform 3 is disposed on a side of the accommodating space 21 away from the opening 22 .

The pen tip 4 is disposed in the accommodating space 21 and penetrates the opening portion 22, and includes an insertion section 41, a writing section 42 and a smooth layer 43. The insertion section 41 is disposed in the accommodating space 21, and includes a supporting portion 411. The supporting portion 411 is close to the opening portion 22, and the width of the supporting portion 411 is greater than the aperture of the through hole 221 to prevent the pen tip 4 from escaping from the accommodating space 21. The writing section 42 is connected to the supporting portion 411 and penetrates the through hole 221, and is used to contact the touch screen. The writing section 42 is in a pointed shape, and in this embodiment, the pen tip 4 is made of a hard material. The smooth layer 43 is located outside the writing section 42 and is disposed on the writing section 42 by plating or coating. The smooth layer 43 may be, for example, a smooth paint or a substance having components such as fluoride, silicone oil, polydimethylsiloxane, benzyl silicone oil, polyquaternary ammonium salt, etc. The smooth layer 43 is used to reduce the surface writing resistance of the writing section 42, and its surface tension may be 1-50 dyn/cm, or the contact angle may be greater than 50 degrees. In this way, the user can smoothly use the touch pen 100 to write on the touch screen with reduced resistance. The pen tip 4 can be switched between an unused position (as shown in FIG. 2 ) in which the insertion section 41 does not abut against the support platform 3 and a used position (as shown in FIG. 3 ) in which the insertion section 41 abuts against the support platform 3 relative to the pen mouth 2. When the pen tip 4 is in the unused position, the writing section 42 contacts the touch screen to move the pen tip 4 toward the support platform 3 until the insertion section 41 abuts against the support platform 3, thereby switching the pen tip 4 from the unused position to the used position.

The buffer 5 is a spring in the present embodiment, and the wire diameter of the spring may be 0.1 mm to 0.6 mm. However, in a modified embodiment, the buffer 5 may be, for example, a soft material, and the details of the soft material will be further described in the following paragraphs. The buffer 5 is connected to the pen tip 4, and specifically, the buffer 5 is arranged around the insertion section 41. The two ends of the buffer 5 are respectively connected to the supporting platform 3 and the abutment portion 411 of the insertion section 41, and when the pen tip 4 is in the use position, the insertion section 41 compresses the buffer 5 to cause the buffer 5 to deform. Thus, when the stylus pen 100 is writing and the pen tip 4 is switched back and forth between the unused position and the used position, the insertion section 41 can reduce the impact force on the support platform 3 through the buffer 5, thereby minimizing the sound generated and improving the quality of use.

Referring to FIG. 4 and FIG. 5 , a second embodiment of the touch pen 100 of the present invention is shown. The second embodiment is similar to the first embodiment, and the differences are: the nib 2, the pen head 4 and the buffer 5. The differences are described in detail below.

The nib 4 is disposed in the accommodation space 21, and the insertion section 41 is disposed through the through hole 221, that is, part of the insertion section 41 and the writing section 42 connected to the insertion section 41 are located outside the nib 2. The width of the abutment portion 411 is greater than the aperture of the through hole 221 to prevent the nib 4 from being completely separated from the accommodation space 21. The width of the writing section 42 is greater than the width of the insertion section 41 to prevent the writing section 42 from entering the accommodation space 21 when the nib 2 is switched from the unused position (as shown in FIG. 4 ) to the used position (as shown in FIG. 5 ). The writing section 42 has a limiting surface 421 facing the opening 22, and the buffer 5 is disposed on the limiting surface 421 and wraps around the insertion section 41, so that the buffer 5 is located between the writing section 42 and the opening 22. In this embodiment, the writing section 42 is an arc shape, but the shape of the writing section 42 can also be the pointed shape of the first embodiment, and the writing section 42 of the first embodiment can also be the arc shape, which can be adjusted according to the needs of the user. When the pen tip 4 is transferred from the unused position to the used position, the writing section 42 moves toward the opening 22 so that the writing section 42 and the opening 22 can compress the buffer 5 together. When the stylus 100 is writing and the pen tip 4 is transferred back and forth between the unused position and the used position, the force of the writing section 42 hitting the opening 22 can be reduced, and the volume of the impact can be reduced. It should be noted that in this embodiment, the buffer 5 is the spring, but in a modified embodiment, the buffer 5 can also be, for example, the soft material. In addition, the support platform 3 can also be provided in the pen mouth 2, so that the insertion section 41 can be pressed against the support platform 3 when it is in the used position.

Referring to FIG. 6 to FIG. 8 , a third embodiment of the touch pen 100 of the present invention is shown. The third embodiment is similar to the first embodiment, and the differences are: the nib 2, the pen head 4 and the buffer 5. The differences are described in detail below.

The pen tip 2 has a groove 23 located in the accommodating space 21 and connected to the opening 22. More specifically, the groove 23 is connected to the through hole 221. The buffer member 5 has a first buffer portion 51 and a second buffer portion 52. The first buffer portion 51 is disposed or filled in the groove 23 and has a slot 511. The slot 511 is connected to the through hole 221 and is used for inserting the insertion section 41 of the pen tip 4, so that the pen tip 4 and the first buffer portion 51 are disposed in the accommodating space 21. The second buffer portion 52 is connected to the first buffer portion 51 and is disposed at the opening portion 22. More specifically, the second buffer portion 52 is disposed at the outer side of the opening portion 22 and is located between the writing section 42 and the opening portion 22. When the pen tip 4 is transferred from the unused position (as shown in FIG. 6 ) to the used position (as shown in FIG. 7 ), the pen tip 4 moves toward the buffer member 5, and the writing section 42 compresses the second buffer portion 52 and the insertion section 41 compresses the first buffer portion 51. When the stylus pen 100 is writing and the pen tip 4 is switched back and forth between the unused position and the used position, the buffer 5 can reduce the force of the pen tip 4 hitting the pen mouth 2, and the volume of the impact can be reduced. In this embodiment, the buffer 5 is the soft material, and the Shore A hardness of the soft material can be 0-80. The soft material can be, for example, foam, silicone, rubber, thermoplastic polyurethane, polyurethane, soft polyvinyl chloride, polypropylene elastomer, thermoplastic elastomer, thermoplastic vulcanizate, polyolefin elastomer, nitrile rubber, soft acrylic, etc., and can be a single material or a combination of multiple materials. In a preferred embodiment, the soft material has electrical conductivity, that is, various metal or carbon components are added to the soft material to make the soft material conductive, so as to increase the capacitance induction of the touch pen 100.

Referring to FIG. 9 , a fourth embodiment of the stylus pen 100 of the present invention is shown. The fourth embodiment is similar to the first embodiment, except that the stylus pen 100 does not include the buffer 5. The difference is described in detail below.

The pen tip 4 is a soft material with electrical conductivity, so that the writing section 42 can directly achieve the buffering function when contacting the touch screen without passing through the buffer 5. The writing section 42 also has a texture structure 422, and the surface roughness Ra of the texture structure 422 is greater than 0.2μm to reduce the writing resistance of the writing section 42. Therefore, in combination with the texture structure 422 and the smooth layer 43, the writing section 42 can write smoothly. In this embodiment, the diameter of the pen tip 4 is not greater than 6mm, and can be the pointed shape or the arc shape. Thereby, the stylus pen 100 can achieve the same buffering capability when the pen tip 4 is made of the soft material, and can also achieve the effects of small size, sharp pen tip and electrical conductivity, so as to improve the defects of the stylus pen with soft pen tip currently on the market, which cannot have a small or sharp pen tip and electrical conductivity at the same time.

In summary, the stylus pen 100 is connected to the pen tip 4 via the buffer 5, or the pen tip 4 is made of the soft material with electrical conductivity, so that the stylus pen 100 can buffer the impact force of the pen tip 4 when writing, thereby reducing the sound emitted. Moreover, when the pen tip 4 is made of the soft material, it can also have electrical conductivity to improve the existing stylus pen that emits a loud sound when used and cannot have the defects of a soft pen tip and capacitor induction, so the purpose of the present invention can be achieved.

However, the above is only an example of the implementation of the present invention, and it should not be used to limit the scope of the implementation of the present invention. All simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the content of the patent specification are still within the scope of the patent of the present invention.
