Description

Technical Field

[0001] This invention relates to the field of touch electronic device technology, and in particular to a stylus and writing device. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] Infrared touch devices consist of a planar detection system comprised of infrared LED emitters and receivers. Common infrared touch devices, such as infrared electronic whiteboards, infrared touchscreens, and infrared touch frames, all have a height difference between the effective infrared detection surface and the actual touch surface of the stylus tip; that is, the effective infrared detection surface is higher than the actual touch surface. This causes the touch effect to be triggered as soon as the stylus enters the infrared detection surface but before it lands on the touch panel.

[0004] When users are writing, their handwriting may appear before they even touch the touch panel, or they may write in cursive script when writing quickly. These issues can lead to accidental touches, greatly affecting the user's writing experience and reducing the reliability of the product. Summary of the Invention

[0005] To address the aforementioned issues, this invention proposes a stylus and writing device that avoids accidental touches and scribbling during writing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] In a first aspect, the present invention provides a stylus, comprising: a light-transmitting pen tip, a pen barrel, and a clamping assembly; one end of the light-transmitting pen tip is threadedly connected to the pen barrel, and the other end of the light-transmitting pen tip passes through the clamping assembly, so as to adjust the length of the light-transmitting pen tip extending through the clamping assembly through the threaded connection; the clamping assembly is connected to the pen barrel to fix the light-transmitting pen tip.

[0008] As an alternative implementation, a thread is provided on the outer wall of one end of the pen tip, and a thread matching the thread of the pen tip is provided on the inner wall of one end of the pen barrel.

[0009] As an alternative implementation, the pen barrel adopts a cavity design; or, the end of the pen barrel connected to the light-transmitting pen tip is provided with a groove.

[0010] As an alternative implementation, one end of the pen barrel is provided with a boss.

[0011] As an alternative implementation, the outer surface of the boss is threaded for threaded connection with the clamping assembly.

[0012] As an alternative implementation, the clamping assembly includes a clamping claw and a clamping housing. The clamping claw is located on the light-transmitting pen tip, and the other end of the light-transmitting pen tip passes through the clamping claw and then through one end of the clamping housing.

[0013] As an alternative implementation, the end of the pressing shell that passes through the light-transmitting pen tip is provided with a through hole so that the light-transmitting pen tip can pass through.

[0014] As an alternative implementation, the other end of the clamping housing is threaded to connect with the pen barrel.

[0015] As an alternative implementation, during the tightening process between the clamping shell and the pen barrel, pressure is applied to the clamping claws to fix the light-transmitting pen tip.

[0016] As an alternative implementation, the clamping shell is made of an opaque material.

[0017] In a second aspect, the present invention provides a writing device, including a writing tablet body and the stylus described in the first aspect.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] This invention proposes a stylus and writing device. The stylus uses a light-transmitting tip and an opaque pen body. When the light-transmitting tip enters the infrared detection surface but has not yet landed on the touch panel, the light-transmitting part of the tip will not be detected by the infrared sensor, so no touch effect will be triggered. When the light-transmitting tip lands on the touch panel, the opaque pen body just enters the infrared detection surface, thereby achieving a touch effect and avoiding problems such as accidental touch and continuous writing.

[0020] This invention proposes a stylus and writing device. The light-transmitting pen tip and pen barrel are connected by a thread, allowing for adjustable tip length. The clamping shell and pen barrel are also connected by a thread. During tightening of the clamping shell, the shell applies pressure to the clamping claws to secure the light-transmitting pen tip. This design can accommodate different height differences between the infrared detection surface and the touch panel. Compared to existing styluses, this significantly reduces the probability of accidental touches.

[0021] Advantages of additional aspects of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0031] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0032] It should be noted that the following detailed descriptions are exemplary and intended to provide further illustration of the invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0033] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments of the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. Furthermore, it should be understood that the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0034] Where there is no conflict, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0035] Example 1

[0036] like Figure 1 As shown, the infrared effective detection surface composed of the transmitting tube and the receiving tube is higher than the actual touch surface of the pen tip, with a height difference D. This causes the touch effect to be triggered when the stylus enters the infrared effective detection surface but has not yet landed on the touch surface, resulting in problems such as continuous writing and accidental touch.

[0037] Based on this, this embodiment provides a stylus, such as... Figure 2-4 As shown, it includes: a light-transmitting pen tip 2, a pen barrel 1, and a clamping assembly; one end of the light-transmitting pen tip 2 is threadedly connected to the pen barrel 1, and the other end of the light-transmitting pen tip 2 passes through the clamping assembly, so as to adjust the length of the light-transmitting pen tip 2 passing through the clamping assembly through the threaded connection; the clamping assembly is connected to the pen barrel 1 to fix the light-transmitting pen tip 2.

[0038] In this embodiment, the connection between the light-transmitting pen tip 2 and the pen barrel 1 is provided with matching threads;

[0039] As an alternative implementation, a thread is provided on the outer wall of one end of the light-transmitting pen tip 2, and a thread matching the thread of the light-transmitting pen tip 2 is provided on the inner wall of one end of the pen barrel 1.

[0040] As an alternative implementation, the pen barrel 1 adopts a cavity design, and the inner wall of one end of the pen barrel 1 is provided with threads that match the threads of the light-transmitting pen tip 2.

[0041] Alternatively, the pen barrel 1 may have a groove at one end where it connects to the light-transmitting pen tip 2. The length of the groove matches the length of the thread on the outer wall of the light-transmitting pen tip 2, so that the light-transmitting pen tip 2 can be screwed into the groove. The light-transmitting pen tip 2 and the pen barrel 1 are connected by a thread to adjust the length of the light-transmitting part of the light-transmitting pen tip 2.

[0042] In this embodiment, one end of the pen barrel 1 is provided with a boss, and the clamping assembly is threadedly connected to the boss.

[0043] As an alternative implementation, the outer surface of the boss is provided with threads that match the clamping assembly, so as to connect with the clamping assembly and fix the light-transmitting pen tip 2.

[0044] In this embodiment, the clamping assembly includes a clamping shell 4 and a clamping claw 3; the clamping claw 3 is disposed on the light-transmitting pen tip 2, and the other end of the light-transmitting pen tip 2 passes through the clamping claw 3 and then through one end of the clamping shell 4. The length of the light-transmitting pen tip 2 passing through the clamping shell 4 is adjusted by a threaded connection, and then the other end of the clamping shell 4 is connected to the pen barrel 1 to fix the light-transmitting pen tip 2.

[0045] As an alternative implementation, the inner side of the other end of the clamping housing 4 is provided with threads to be threadedly connected to the pen barrel 1. During the tightening process of the clamping housing 4, pressure is applied to the clamping claw 3 to fix the light-transmitting pen tip 2 through the clamping claw 3.

[0046] As an alternative implementation, the pressing shell 4 has a through hole at one end of the light-transmitting pen tip 2 so that the light-transmitting pen tip 2 can pass through.

[0047] As an alternative implementation, the clamping shell 4 is made of an opaque material.

[0048] As an alternative implementation, the clamping housing 4 can be a clamping nut.

[0049] In this embodiment, the light-transmitting pen tip 2 can be made of conventional light-transmitting material, as long as it is not detected by infrared radiation; for example, the light transmittance of the pen tip can be designed to be greater than 80%.

[0050] In this embodiment, as Figure 5 As shown, the light-transmitting pen tip is made of a light-transmitting material, while the pen body is made of a non-light-transmitting material. When the light-transmitting pen tip enters the infrared detection surface but has not yet landed on the touch panel, the light-transmitting part of the pen tip will not be detected by the infrared sensor, so the touch effect will not be triggered. Figure 6 As shown; therefore, when the light-transmitting tip of the stylus touches the touch panel, the opaque part of the stylus shaft enters the infrared detection surface, thus achieving a touch effect, as shown. Figure 7 As shown.

[0051] In this embodiment, the light-transmitting pen tip and the pen barrel are connected by a thread, allowing for adjustment of the pen tip's length. The clamping shell and the pen barrel are also connected by a thread. During the tightening process of the clamping shell, the shell applies pressure to the clamping claws, which firmly hold the light-transmitting pen tip. This design can accommodate different height differences between the infrared detection surface and the touch panel. Compared to existing styluses, this significantly reduces the probability of accidental touches.

[0052] Example 2

[0053] This embodiment provides a writing device, including a writing tablet body and the stylus described in Embodiment 1.

[0054] In this embodiment, the writing board body may be an infrared touch device, including an infrared electronic whiteboard, an infrared touch screen, an infrared touch frame, etc.

[0055] While the specific embodiments of the present invention have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of the present invention are still within the scope of protection of the present invention.
