Description

Technical Field

[0001] The utility model relates to a control pen, in particular to a telescopic touch screen writing control pen. Background Art

[0002] With the popularity of touch screen technology, stylus pens have been widely used in smartphones, tablets and other touch devices to provide a more precise input method than fingers. Traditional stylus pens mainly rely on capacitive or resistive screen technology to operate, and execute input instructions by simulating human body current or pressure changes. However, these traditional stylus pens have some significant limitations and shortcomings.

[0003] First, many existing styluses can trigger signals when they are at a certain distance from the screen. This "floating trigger" may lead to misoperation, especially when performing delicate operations such as drawing or writing, which may cause unnecessary strokes or line breakage. In addition, this triggering method lacks the necessary feedback mechanism, and it is difficult for users to sense whether the pen tip has touched the screen, thus affecting the accuracy of the operation and the user experience.

[0004] Secondly, the stylus pens in the prior art are usually simple in design, and most lack mechanical or electronic adjustment mechanisms that can adapt to different user operating habits and pressure changes. This limits the applicability and flexibility of the stylus in different application scenarios, especially in professional applications that require highly precise control.

[0005] Therefore, there is an urgent need to develop a new stylus design that can solve the problem of misoperation, provide more accurate control, and have higher durability and easier maintenance. Utility Model Content

[0035] like Figure 1 and Figure 2 As shown, a retractable touch screen writing control pen of the utility model comprises a pen body 1, wherein the interior of the pen body 1 has a hollow receiving cavity for installing a control mainboard 7 and a battery 8;

[0036] It also includes a retractable pen tip 3, which is mounted on the pen body 1. The head of the pen tip 3 is a writing contact portion 4. A signal trigger component is installed inside the pen tip 3 and the pen body 1.

[0039] like Figure 3 as well as Figure 4 As shown, the signal trigger component includes three signal pads arranged on the control main board 7;

[0040] And an antenna hardware fixing sleeve 15, a pen tip hardware brace, an antenna hardware brace 22, and a center tube 26 fixing sleeve 14, the pen tip 3 hardware brace is threadedly connected and assembled with the antenna hardware brace 22, the other end of the pen tip hardware brace is sleeved in the pen tip 3, the antenna hardware fixing sleeve 15 is installed on the outside of the antenna hardware brace 22, one side of the center tube 26 fixing sleeve 14 is arranged on one side of the antenna hardware fixing sleeve 15 and docked with one side of the antenna hardware brace 22, the other side of the center tube 26 fixing sleeve 14 is positioned and supported with one side of the elastic reset member 13, and the other side of the elastic reset member 13 is welded and fixed to the first signal pad 12 among the three signal pad positions.

[0041] like Figure 4 As shown, a central tube 26 is provided in the hollow position inside the antenna hardware brace 22, one side of the central tube 26 is positioned and installed in the central tube 26 fixing sleeve 14, and a spring pin assembly 23 is installed on the other side, one end of the spring pin assembly 23 is located outside the central tube 26, and the other end is inserted into the central tube 26, and a pair of connecting tubes 24 for docking and conduction are provided on one side of the spring pin assembly 23 located inside the central tube 26, and a top signal line 19 is provided through the connecting tube 24, one end of the top signal line 19 is connected to the spring pin assembly 23, and the other end passes through the entire central tube 26 and the central tube 26 fixing sleeve 14 and extends from the outlet slot 18 opened on the central tube 26 fixing sleeve 14 to the outside and then connects to the second signal pad 10 among the three signal pad positions.

[0042] An outer tube signal line 17 is installed on the joint of the wire hardware fixing sleeve, and the other end of the outer tube signal line 17 is connected to the third signal pad 11 among the three signal pad positions.

[0043] In order to make the movement of the central tube 26 smoother, in the present embodiment, a guide sleeve 21 is provided at the opening positions on both sides of the pen tip hardware brace, and both sides of the central tube 26 pass through the guide sleeve 21 and extend to the outside of the guide sleeve 21.

[0044] An inwardly protruding limit bead 16 is provided on the antenna hardware fixing sleeve 15, and a limit guide groove 20 is provided on the antenna hardware brace 22 corresponding to the position of the limit bead 16. The inwardly protruding limit bead 16 is buckled into the limit guide groove 20. By setting the limit bead 16, the downward pressure of the pen tip 3 can be guaranteed to be within the set stroke, so that it will not damage the internal components due to excessive downward pressure.

[0045] like Figure 2 As shown, an antenna housing 6 is installed outside the pen tip hardware brace 25 and the antenna hardware fixing sleeve 15, and a bracket is arranged to dock with one side of the antenna housing 6. The control main board 7 and the battery 8 are both installed in the bracket. The bracket includes a first bracket 5 and a second bracket 9. After the first bracket 5 and the second bracket 9 are spliced, an open installation cavity is exposed on the second bracket 9, and the battery 8 and the control main board 7 are both installed in the installation cavity.

[0046] When the writing contact portion 4 of the pen tip 3 is pressed, the elastic reset member 13 is elastically compressed, and the central tube 26 fixing sleeve 14 and the antenna hardware fixing sleeve 15 are disconnected and a telescopic gap L is formed. At this time, the signal trigger component is turned on to obtain communication with the external device. The spacing of the telescopic gap L is the telescopic distance of the pen tip 3. After pressing down, the telescopic gap L is 0;

[0047] When the pressure applied to the signal trigger component is released, the central tube 26 fixing sleeve 14 is reset by the elastic reset member 13 arranged in the pen body 1, and the central tube 26 fixing sleeve 14 is brought into contact with the antenna hardware fixing sleeve 15. At this time, the signal is short-circuited and the communication with the external device is disconnected.

[0048] In order to achieve continuous power supply, a charging board is further provided in the pen body 1 of the present embodiment. The charging board is connected to the control main board 7 , and a charging interface 2 is further provided on one side of the charging board.

[0049] In this embodiment, the elastic reset member 13 is a metal spring, which achieves the functions of conductivity and elastic reset.

[0050] The core of the utility model lies in the retractable pen tip 3, whose working principle is based on the close cooperation of the mechanical retractable structure and the electrical signal transmission system. When the user applies pressure to the touch screen through the pen tip 3, the pen tip 3 will shrink slightly. This shrinkage is achieved by an internal elastic reset member 13 (such as a metal spring), allowing the pen tip 3 to move inward when pressure is applied, and automatically reset to the original position when the pressure is relieved.

[0051] A signal trigger component is provided inside the pen tip 3. The control main board 7 is responsible for processing the interactive signal between the pen tip 3 and the touch screen. The retracting action of the pen tip 3 will trigger the signal pad position on the control main board 7 and activate the communication with the touch screen.

[0052] When the operator touches the touch screen with the pen tip, the physical pressure causes the pen tip to retract slightly into the pen body 1, usually within the range of 0.1 to 1.0 mm. The retracting action can activate the internal spring needle assembly 23, so that the spring needle moves toward the signal pad position on the control main board 7, forming a closed circuit. At this time, the signal is transmitted to the external device through the antenna or other connection facilities to achieve communication with the touch screen, thereby supporting continuous writing or drawing functions.

[0053] When the user completes the operation and lifts the pen tip, the internal elastic reset member 13 returns the pen tip to its initial position, disconnects from the signal pad, and thus disconnects the communication with the touch screen, ending the writing or drawing operation. In addition, the top signal line 19 and the outer tube signal line 17 in the pen body 1 are both connected to the signal pad to ensure stability and continuity during the signal transmission process. Through this structure, the retractable touch screen writing control pen can not only effectively avoid false triggering, but also improve the accuracy and efficiency of writing and drawing, meeting the needs of high-precision operations.

[0054] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
