Description

Pen stand device and touch control pen

Technical Field

The present invention relates to a pen holder device for repairing the loss of a stylus pen tip, and more particularly, to a pen holder device for repairing the loss of a stylus pen tip by using a photo-curing method.

Background

The active capacitive pen/touch pen achieves electric field output by preloading a voltage at the pen point, receives the periodic electric field through the touch sensor end to calculate the actual position of the pen point above the touch screen, and then performs corresponding output, so that the use is convenient. Therefore, the conductive material (e.g., metal, highly conductive plastic) is usually selected as the refill for the pen tip, and the non-conductive material is selected to cover the pen tip surface for the purpose of smooth appearance and writing.

Disclosure of Invention

The invention provides a pen holder device capable of changing pen point writing hand feeling and pen point friction force of a touch pen. The pen seat device forms high-friction layers with different hardness and different friction coefficients for coating the pen point in a photocuring mode, and further maintains the friction force of the pen point. Therefore, the hardness and the handfeel of the pen point can be changed according to the requirements and the preferences of users. When the pen point is worn, the light curing can be carried out again to maintain the original writing hand feeling. In addition, when the light curing is carried out, the pen seat device can also supply power to the touch control pen at the same time.

The pen holder device provided by the invention at least comprises a groove for storing the colloid and a light source for curing the photosensitive colloid. After the pen point of the touch pen is fully stained with the light sensitive colloid, the light sensitive colloid can be solidified through the irradiation of the light source. The photosensitive colloid is prepared by adding photoinitiator (or photosensitizer) into colloid. When the photosensitive colloid absorbs enough light energy, the photosensitive colloid is converted from liquid state to solid state.

An embodiment of the present invention provides a pen holder device for loading a stylus. The pen holder device comprises a first groove, a second groove, a control circuit, a charging device and at least one light source. The second groove is communicated with the first groove and filled with photosensitive colloid. When a user puts the touch control pen into the pen seat device, a pen head of the touch control pen enters the second groove through the first groove, and the light sensitive colloid is attached to one surface of the pen head. The charging device is connected to the control circuit, and when the touch pen is placed in the pen holder device, the control circuit controls the charging device to charge the touch pen. The at least one light source is connected to the control circuit. After the photosensitive adhesive is attached to the surface of the pen point, the control circuit turns on the at least one light source to irradiate the pen point, so that the photosensitive adhesive attached to the surface is cured to form a high-friction layer.

An embodiment of the invention provides a touch pen, which is used for being matched with a pen holder device. The touch control pen comprises a sensor, a charging circuit, a microcontroller, a battery and a pen point. The microcontroller is connected to the sensor and the charging circuit. The battery is connected to the charging circuit. The pen point is connected to the sensor. When a user puts the touch control pen into the pen seat device, the pen point enters the second groove of the pen seat device through the first groove of the pen seat device, and the light-sensitive colloid filled in the second groove is attached to one surface of the pen point. When the sensor detects that the touch pen is put into the pen holder device, the microcontroller starts the charging circuit to receive power from the pen holder device. When the user puts the touch control pen into the pen seat device, at least one light source of the pen seat device irradiates the pen head, so that the light sensitive colloid attached to the surface is solidified to form a high friction layer.

In order to make the aforementioned and other features and advantages of the invention more comprehensible, embodiments accompanied with figures are described in detail below.

Illustrative embodiments or examples of the present disclosure are described below. The scope of the present disclosure is not limited thereto. Those skilled in the art should appreciate that they may make various changes, substitutions and alterations herein without departing from the spirit and scope of the present disclosure. Reference numerals may be repeated among the embodiments of the disclosure, and various embodiments of the disclosure may share the same reference numerals, but feature elements used in one embodiment are not necessarily used in another embodiment.

Fig. 1 is a block diagram illustrating a stylus 10 according to an embodiment of the invention. The stylus 10 includes a pen head 11, a sensor 12, a signal generator 13, a microcontroller 14, a button switch 15, a battery 16 and a charging circuit 17. The sensor 12 is connected to the pen tip 11. The microcontroller 14 is connected to the sensor 12, the signal generator 13, the push-button switch 15 and the charging circuit 17, respectively. The battery 16 is connected to a charging circuit 17. Stylus 10 may be an active capacitive stylus, a stylus, an electronic pen, or other electronic devices similar to an electronic pen, sensor 12 may be a pressure sensor, a touch sensor, or other related type of sensor, and charging circuit 172 may be a wireless charging coil, but the invention is not limited thereto.

In an embodiment of the present invention, when the contact layer/high friction layer outside the tip 11 of the stylus 10 is worn, the user can place the stylus 10 into a glue tank filled with photosensitive glue. Then, a high-friction layer with different hardness and different friction coefficient is formed to cover the pen tip 11 by photo-curing (for example, ultraviolet light is used to irradiate the photosensitive adhesive attached on the pen tip 11), so as to maintain the friction force of the pen tip 11. Therefore, the user can maintain the original writing feeling of the pen point 11 or change the writing feeling of the pen point 11 through the above operation mode.

In another embodiment of the present invention, the glue groove is disposed as a second groove 22 of the pen holder device 20, wherein the pen holder device 20 includes a first groove 21, the second groove 22 and at least one light source 25. The light source 25 may be an ultraviolet light source or other light source that can be photocured. In this embodiment, when the tip 11 of the stylus 10 is worn, the user can put the stylus 10 into the pen holder device 20 for filling. When the user puts the touch pen 10 into the pen holder device 20, the pen tip 11 enters the second groove 22 of the pen holder device 20 through the first groove 21 of the pen holder device 20, so that the light-sensitive adhesive filled in the second groove 22 adheres to the surface of the pen tip 11. In the present embodiment, when the sensor 12 detects that the stylus 10 is inserted into the pen holder apparatus 20, the microcontroller 14 turns on the charging circuit 17 to receive power from the pen holder apparatus 20. Meanwhile, when the user puts the stylus 10 into the pen holder device 20, at least one light source 25 of the pen holder device 20 irradiates the pen head 11, so that the photosensitive adhesive attached to the surface is cured to form a high-friction layer.

In another embodiment of the present invention, when the sensor 12 senses that the photosensitive adhesive is attached to the surface of the pen tip 11, the microcontroller 14 controls the signal generator 13 to generate a signal to the pen holder device 20. The signal informs the pen holder device 20 to turn on at least one light source 25 of the pen holder device 20 to irradiate the pen tip 11, so that the photosensitive adhesive attached to the surface of the pen tip 11 is cured to form the high-friction layer. Similarly, the signal may also inform the pen stand device 20 to charge the stylus 10.

FIGS. 2A to 2C are schematic views illustrating the formation of the high friction layer 111 on the nib 11 according to the embodiment of the present invention. In FIG. 2B, the broken line indicates the range where the high-friction layer is intended to be formed on the surface of the nib 11. In fig. 2C, the pen tip 11 is dipped with a photosensitive adhesive, and the light curing is performed by irradiating the pen tip 11 with a light source (e.g., an ultraviolet light source). In FIG. 2D, the photosensitive adhesive attached to the surface of the pen tip 11 is cured to form the high-friction layer of the pen tip 11.

Fig. 3A to 3F are schematic views illustrating the formation of the high friction layer 111 on the tip 11 of the stylus 10 in the pen holder apparatus 20 according to the embodiment of the invention. In the embodiment shown in fig. 3A to 3F, the present invention provides a pen holder device 20 carrying a stylus 10, wherein the pen holder device 20 includes a first recess 21, a second recess 22, a control circuit 23, a charging device 24 and at least one light source 25. The first recess 21 communicates with the second recess 22. The second groove 22 is filled with a photosensitive gel. The control circuit 23 is connected to the charging device 24 and the at least one light source 25, respectively, wherein the at least one light source 25 is arranged on a wall of the first recess 21 or on a wall of the second recess 22. The light source 25 may be an ultraviolet light source or other light source that can be photocured.

In fig. 3B, the user places the stylus 10 into the pen stand apparatus 20. At this time, the tip 11 of the stylus 10 enters the second groove 22 through the first groove 21, so that the tip 11 is immersed in the photosensitive adhesive in the second groove 22. In fig. 3C, the stylus 10 leaves the second recess 22 and returns to the first recess 21. At this time, the photosensitive adhesive in the second groove 22 is attached to the surface of the pen tip 11. At the same time, the control circuit 23 turns on the charging device 24 to charge the stylus pen 10.

In fig. 3D, the stylus 10 is located in the first groove 21 and the photosensitive adhesive is attached to the pen tip 11. At this time, the control circuit 23 turns on at least one light source 25 to illuminate the pen tip 11. In fig. 3E, after the irradiation time, the photosensitive colloid attached to the surface is cured to form a high friction layer 111. In fig. 3F, after the stylus 10 is charged, the user takes the stylus 10 away from the pen stand device 20.

In another embodiment of the present invention, the control circuit 23 of the pen holder device 20 further adjusts an illumination time and an output power of the at least one light source 25 according to a charging time of the stylus 10, so that the curing of the pen tip 11 and the charging of the stylus 10 can be completed at the same time.

In another embodiment of the present invention, the pen stand device 20 further comprises an adjusting device 230, wherein the adjusting device 230 is connected to the control circuit 23. The adjusting device 230 may be, for example, a touch screen disposed on the pen holder device 20, but the invention is not limited thereto. In this embodiment, the user can input the self-determined photocuring time on the adjusting device 230 (the touch screen). Then, the control circuit 23 adjusts the illumination time of the at least one light source 25 and the corresponding output power required by illumination according to the photocuring time. In addition, the control circuit 23 can also adjust the charging time of the charging device 24 for the stylus 10 and the corresponding output power required for charging according to the photocuring time, so that the user can take the stylus 10 away earlier.

In this embodiment, when the user only needs to cure the pen tip 11, the user can also inform the control circuit 23 through the adjustment device 230 that the stylus 10 does not need to be charged (for example, the user selects the light curing mode on the touch screen and turns off the charging mode). At this time, the control circuit 23 increases the output power of the at least one light source 25 to accelerate the curing process of the adhesive.

Fig. 4 is a schematic diagram of a pen stand device 20 according to another embodiment of the present invention. In the detailed embodiment of fig. 4, the charging circuit 17 of the stylus 10 is a wireless charging coil 170, and the charging device 24 of the pen holder device 20 is a wireless charging power source.

Fig. 5 is a schematic view of a pen stand device 20 according to another embodiment of the present invention. In the detailed embodiment of fig. 5, a spring member 261 and a spring member 262 are also provided in the pen stand device 20. First, when the user puts the stylus 10 into the holder device 20, the tip 11 of the stylus 10 enters the second groove 22 through the first groove 21, so that the surface of the tip 11 is immersed in the photosensitive adhesive in the second groove 22. Then, after the tip 11 enters the second groove 22, the restoring forces of the

spring members

261 and 262 pull the stylus 10, so that the tip 11 of the stylus 10 is separated from the second groove 22 and fixed in the first groove 21. Through the arrangement of the

spring members

261 and 262, the pen holder device 20 can fix the stylus pen 10 in the first groove 21 to complete the photo-curing and charging operations.

Fig. 6 is a schematic view of a pen stand device 20 according to another embodiment of the present invention. In the detailed embodiment of fig. 6, compared to the stylus pen 10 and the pen holder apparatus 20 of fig. 5, the stylus pen 10 and the pen holder apparatus 20 are further provided with charging holes at the contact points (e.g., the contact points 171 and 172 of the stylus pen 10 and the contact points 271 and 272 provided on the first groove 21 of the pen holder apparatus 20 shown in fig. 6) of the stylus pen 10 and the pen holder apparatus 20, respectively, so that the stylus pen 10 can be charged quickly when being placed on the pen holder apparatus 20.

Fig. 7 is a schematic view of a pen stand device 20 according to another embodiment of the present invention. In the detailed embodiment of fig. 7, a magnetic device 263 (e.g., a magnet) is further disposed in the pen holder device 20. First, when the user puts the stylus 10 into the pen holder device 20, the tip 11 of the stylus 10 enters the second groove 22 through the first groove 21, so that the tip 11 is immersed in the photosensitive adhesive in the second groove 22. Then, while the pen tip 11 enters the second groove 22, the magnetic attraction of the magnetic device 263 pulls the stylus 10 away from the second groove 22 and fixes the stylus in the first groove 21.

Similar to the embodiment of fig. 6, in the detailed embodiment of fig. 7, the touch pen 10 and the pen holder device 20 are respectively provided with charging holes (for example, the charging

holes

173 and 174 of the touch pen 10 and the charging seat 273 of the pen holder device 20 shown in fig. 7) at the contact positions of the touch pen 10 and the pen holder device 20, so that when the touch pen 10 is fixed in the first recess 21, the charging seat 273 of the charging device 24 of the pen holder device 20 charges the touch pen 10 through the charging

holes

173 and 174.

Fig. 8 is a schematic view illustrating an internal mechanism of the pen stand device 20 according to another embodiment of the present invention. The pen stand apparatus 20 shown in fig. 8 may be a more detailed embodiment of the pen stand apparatus 20 shown in fig. 5, or may be a more detailed embodiment of the pen stand apparatus 20 shown in fig. 6. In the detailed embodiment of FIG. 8, the pen stand apparatus 20 further includes a cover 28 and a linkage assembly 29. The upper cover 28 is coupled to the linkage assembly 29 and disposed between the first recess 21 and the second recess 22. The upper cover 28 of the pen holder assembly 20 includes an actuator 281 and an actuator 282, and the linkage assembly 29 of the pen holder assembly 20 includes a spring member 261, a spring member 262, an actuator 291, an actuator 292, a gear 293, a gear 294, a gear 295, and a gear 296.

In the present embodiment, when the user puts the stylus 10 into the pen holder device 20 and touches the linkage element 29, the linkage element 29 opens the upper cover 28, so that the pen tip 11 of the stylus 10 enters the second groove 22 through the first groove 21. More specifically, stylus 10 simultaneously presses on actuator 291 and actuator 292 of linkage assembly 29, causing actuator 291 and actuator 292 to press spring member 261 and spring member 262, respectively, and to pull gear 293 and gear 295, respectively. At this time, the counterclockwise rotation of gear 293 and the clockwise rotation of gear 294 cause the actuator 281 of the upper cover 28 to move to the left, and the clockwise rotation of gear 295 and the counterclockwise rotation of gear 296 cause the actuator 282 of the upper cover 28 to move to the right. The left movement of the actuator 281 and the right movement of the actuator 282 causes the upper cover 28 to open to allow the tip 11 of the stylus 10 to enter the second groove 22.

In the present embodiment, when the user releases the stylus 10, the linking component 29 pulls the stylus 10, so that the tip 11 of the stylus 10 is separated from the second groove 22 and fixed in the first groove 21. Then, after the user releases the stylus 10, the interlocking member 29 closes the upper cover 28. More specifically, the user releasing stylus 10 causes the restoring forces of

spring members

261 and 262 to push up on actuator 291 and actuator 292, causing actuator 291 and actuator 292 to pull on gear 293 and gear 295, respectively. At this time, the clockwise rotation of the gear 293 and the counterclockwise rotation of the gear 294 cause the actuator 281 of the upper cover 28 to move to the right, and the counterclockwise rotation of the gear 295 and the clockwise rotation of the gear 296 cause the actuator 282 of the upper cover 28 to move to the left. Movement of the actuator 281 to the right and the actuator 282 to the left causes the upper cover 28 to close. The advantage of closing the cover 28 is that when the light source 25 is turned on, the light emitted from the light source 25 will not irradiate the photosensitive adhesive filled in the second groove 22, thereby avoiding the problem of curing of the photosensitive adhesive.

In the embodiments of the present invention of fig. 4 to 8, the light source 25 may be disposed on the groove wall of the second groove 22 (bottom illumination) in addition to the groove wall of the first groove 21 (side illumination). In addition, in another embodiment of the pen stand device 20 shown in fig. 8, the light source 25 may also be disposed on the upper cover 28.

Fig. 9A and 9B are top views illustrating the configuration of at least one light source 25 according to another embodiment of the present invention. In the embodiment of fig. 9A, the at least one light source 25 is 4 in number and symmetrically disposed on the walls of the first recess 21. In the embodiment of fig. 9B, the at least one light source 25 is 8 in number and symmetrically disposed on the walls of the first recess 21.

In various embodiments of the present invention, the light-sensitive colloid/light-sensitive glue material filled in the colloid groove (the second groove 22) is selected by referring to the known light-sensitive glue materials listed in the following tables 1, 2 and 3, but the present invention is not limited thereto.
