Description

Technical Field

[0001] The present invention relates to the technical field of capacitive pens, and specifically to a voice reminder device for a capacitive pen and a control method therefor. Background Art

[0002] A capacitive pen is also a touch pen and can be used in enterprise OA, ERP systems, collaborative systems or the intranets of professional institutions. Its appearance facilitates people's use. It not only has a simple structure but also is easy to operate. With the popularization of electronic products, the usage scenarios of Bluetooth capacitive pens in combination with electronic devices such as tablets are becoming more and more extensive. Usually, before using a Bluetooth capacitive pen in combination with an electronic device for writing or drawing, it is necessary to first pair the Bluetooth capacitive pen with the electronic device and establish a Bluetooth connection;

[0003] However, currently, when the capacitive pen is not in use, the pen tip is always exposed. When the capacitive pen accidentally rolls onto the ground, the exposed pen tip is easily damaged by external force impacts, thus affecting the service life of the capacitive pen. Moreover, currently, when using a capacitive pen, it is impossible to correct the writing posture of the user. If the user holds the pen in an incorrect posture for a long time, it will not only affect the writing effect, but more seriously, it will endanger the user's physical health, causing myopia, strabismus and spinal curvature;

[0004] To solve the above problems, a voice reminder device for a capacitive pen and a control method therefor are proposed in this application. Summary of the Invention

[0005] The present invention aims to provide a voice reminder device for a capacitive pen and a control method therefor, mainly to solve the problem that the pen tip of the existing capacitive pen is easily damaged when it is exposed, and currently, when using a capacitive pen, it is impossible to correct the writing posture of the user, which not only affects the writing effect but may even cause myopia, strabismus and spinal curvature of the user.

[0006] To solve the above technical problems, the present invention provides the following technical solutions:

[0007] A voice reminder device for a capacitive pen, comprising a pen barrel. The lower end of the pen barrel is detachably connected with a pen tip. The lower end of the outer wall of the pen barrel is slidably connected with a protective shell for protecting the pen tip. The outer wall of the pen barrel is provided with a limiting component for fixing the protective shell. The bottom of the inner wall of the pen barrel is fixedly installed with a main board, and a Bluetooth module, a data processing module and a timing module are fixedly installed on the main board. A battery is fixedly installed above the main board inside the pen barrel. An inclination sensor is fixedly installed above the battery inside the pen barrel. An installation block is fixedly connected above the inclination sensor inside the pen barrel. A speaker is fixedly installed on the installation block. A plurality of through holes matching the speaker are opened on the outer wall of the pen barrel, and the through holes are equidistantly distributed on the pen barrel in a linear array. A charging interface for charging the battery is opened at the upper end of the outer wall of the pen barrel. A protective component for protecting the charging interface is fixedly connected above the charging interface at the upper end of the outer wall of the pen barrel.

[0008] The working principle and beneficial effects of the present invention:

[0009] 1. Working principle: When using this capacitive pen, insert one end of the charger into the charging interface, and then connect the charger to the power supply to charge the battery inside the pen barrel. The charging interface is a Type-c interface, which is applicable to most chargers on the market. After the battery is fully charged, unplug the charging cable, then release the limiting component and slide the protective shell upward to expose the pen tip. After the protective shell slides upward to a certain extent, fix the protective shell through the limiting component. Then bring the capacitive pen close to the electronic device. The Bluetooth module on the main board inside the pen barrel automatically matches and connects with the electronic device. When the connection is successfully displayed on the electronic device, the capacitive pen can be used normally. During the use of the capacitive pen, the inclination sensor inside the pen barrel detects the inclination characteristics of the pen barrel. After the inclination sensor detects the inclination characteristics of the pen barrel, it will send an electrical signal to the data processing module on the main board. The data processing module analyzes and processes the data. If the user's pen-holding posture is correct, the capacitive pen can be used normally. If the user's pen-holding posture is incorrect, the data processing module will send an electrical signal to the speaker, and the speaker will emit a voice reminder after receiving the electrical signal, so as to remind the user to correct the pen-holding posture in time.

[0010] 2. Beneficial effects:

[0011] (1) By providing a protective shell at the lower end of the outer wall of the pen barrel, when the capacitive pen is not needed, the protective shell can be slid downward, and the pen tip can be wrapped inside by the protective shell, so as to play a good protection role for the pen tip, and thus effectively extend the service life of the capacitive pen;

[0012] (2) By providing an inclination sensor inside the pen barrel, if the user's pen-holding posture is incorrect, the inclination sensor will send an electrical signal to the data processing module. After the data processing module analyzes and processes the data, it will send an electrical signal to the speaker, and the speaker will emit a voice reminder after receiving the electrical signal, so as to remind the user to correct the pen-holding posture in time;

[0013] (3) The charging interface provided at the upper end of the pen shaft can charge the battery inside the capacitive pen. After charging, the protective component can play a good protective role for the charging interface, thus effectively preventing a large amount of dust from entering the inside of the charging interface and damaging the capacitive pen, and further effectively extending the service life of the capacitive pen.

[0014] Preferably, the limiting component includes sliding cavities opened on the outer wall of the pen shaft, and the sliding cavities are symmetrically arranged on the pen shaft. The inside of each sliding cavity is slidably connected with a limiting block. One end of the limiting block extends out of the sliding cavity, and the other end is fixedly connected with a spring. The other end of the spring is fixedly connected with the inner wall of the sliding cavity. The upper end of the outer wall of the protective shell is provided with a limiting groove matching the limiting block. The inner wall of the limiting groove is fixedly connected with a button. One end of the button extends out of the limiting groove, and the other end abuts against the limiting block. When using the capacitive pen, pressing the button can push the limiting block to slide into the inside of the sliding cavity. When the limiting block disengages from the limiting groove on the protective shell, the protective shell can be slid upward to expose the pen tip. Press the limiting block inside the sliding cavity above the pen shaft to make it enter the inside of the sliding cavity, and then continue to slide the protective shell upward to a certain extent. The limiting block inside the sliding cavity above the pen shaft will pop out under the action of the spring and be clamped with the limiting groove, and the capacitive pen can be used normally. After the capacitive pen is used up, press the button to make the limiting block inside the sliding cavity above the pen shaft disengage from the limiting groove, and then slide the protective shell downward. When the pen tip completely enters the inside of the protective shell, the limiting block inside the sliding cavity below the pen shaft will pop out under the action of the spring and be clamped with the limiting groove. At this time, the protective shell can play a good protective role for the pen tip, thus effectively extending the service life of the capacitive pen.

[0015] Preferably, the protective component includes a rubber strip fixedly connected above the charging interface at the upper end of the outer wall of the pen shaft. One end of the rubber strip away from the pen shaft is fixedly connected with a rubber cover. The bottom of the rubber cover is fixedly connected with a dust-proof plug matching the charging interface. After the capacitive pen is charged, pull the rubber cover to insert the dust-proof plug at its bottom into the charging interface, which can effectively prevent a large amount of dust from entering the inside of the charging interface and damaging the capacitive pen, thereby further effectively extending the service life of the capacitive pen.

[0016] Preferably, a fixing block is fixedly connected to the top of the nib, a threaded post is fixedly connected to the bottom of the inner wall of the pen barrel, a threaded hole matching the threaded post is formed in the top of the fixing block, the threaded post is threadedly connected to the inner wall of the threaded hole, and the nib is threadedly connected to the lower end of the pen barrel. This not only makes the connection between the nib and the pen barrel relatively firm, but also makes the disassembly and assembly of the nib more convenient. When the nib is damaged after long-term use of the capacitive pen, it is convenient for the user to replace the nib. An annular groove is formed in the lower end of the outer wall of the fixing block. Through the annular groove formed in the lower end of the outer wall of the fixing block, after the nib is installed at the lower end of the pen barrel, the lower end of the inner wall of the pen barrel will be clamped with the annular groove, which can provide a better fixing effect on the nib, thereby making the nib more stable after installation.

[0017] Preferably, a rubber skin is fixedly connected to the bottom of the inner wall of the protective shell, and a cross groove is formed in the rubber skin. Through the rubber skin provided at the bottom of the inner wall of the protective shell, when the protective shell wraps the nib inside, a good dust-proof effect can be achieved through the rubber skin, thereby providing a better protection effect on the nib.

[0018] Preferably, a guiding block is fixedly connected to the inner wall of the protective shell, and a guiding groove matching the guiding block is formed in the outer wall of the pen barrel. During the up and down sliding of the protective shell, through the guiding block provided on the inner wall of the protective shell and the guiding groove formed in the outer wall of the pen barrel, a good limiting and guiding effect can be achieved on the protective shell, so that the protective shell can only slide in the vertical direction of the pen barrel, thereby making the up and down sliding of the protective shell more stable.

[0019] Preferably, a ball is rotatably connected to one end of the limiting block extending out of the sliding cavity. When the protective shell slides up and down, one end of the limiting block is always in contact with the inner wall of the protective shell under the action of the spring. Through the ball provided at one end of the limiting block, the friction between the limiting block and the inner wall of the protective shell can be effectively reduced. This not only makes it easier and more labor-saving for the user to slide the protective shell up and down, but also can effectively reduce the wear between the limiting block and the protective shell.

[0020] Preferably, the number of speakers is two, and the speakers are symmetrically arranged on the mounting block. By setting the number of speakers on the mounting block to two, the volume of the voice reminder of the capacitive pen can be effectively increased, thereby providing a better correction effect on the user's pen-holding posture.

[0021] Preferably, a rubber sleeve is sleeved on the outer wall of the protective shell, and anti-slip patterns are formed on the outer wall of the rubber sleeve. Through the rubber sleeve sleeved on the outer wall of the protective shell, the user's hand can be made more comfortable when holding the pen. Through the anti-slip patterns provided on the outer wall of the rubber sleeve, the friction between the user's hand and the capacitive pen can be increased, thereby effectively preventing the user's hand from slipping when holding the pen.

[0022] Preferably, a voice reminder control method for a capacitive pen includes the following steps:

[0023] A: Insert one end of the charger into the charging interface, then connect the charger to the power supply to charge the battery inside the pen barrel. After the battery is fully charged, unplug the charging cable.

[0024] B: Bring the capacitive pen close to the electronic device. The Bluetooth module on the main board inside the pen barrel will automatically match and connect with the electronic device. When the connection is successfully displayed on the electronic device, the capacitive pen can be used normally.

[0025] C: During the use of the capacitive pen, the inclination sensor detects the inclination characteristics of the pen barrel. After the inclination sensor detects the inclination characteristics of the pen barrel, it will send an electrical signal to the data processing module on the main board.

[0026] D: The data processing module analyzes and processes the data. If the user's pen-holding posture is correct, the capacitive pen can be used normally. If the user's pen-holding posture is incorrect, the data processing module will send an electrical signal to the speaker, and the speaker will emit a voice reminder after receiving the electrical signal to remind the user to correct the pen-holding posture in time.

Detailed implementation manner

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0038] Please refer to Figure 1-9, a voice reminder device for a capacitive pen, including a pen shaft 1. A nib 2 is detachably connected to the lower end of the pen shaft 1. A fixing block 21 is fixedly connected to the top of the nib 2. A threaded column 22 is fixedly connected to the bottom of the inner wall of the pen shaft 1. A threaded hole 23 matching the threaded column 22 is provided in the top of the fixing block 21. The threaded column 22 is threadedly connected to the inner wall of the threaded hole 23. The nib 2 is threadedly connected to the lower end of the pen shaft 1. This not only makes the connection between the nib 2 and the pen shaft 1 relatively firm, but also makes the disassembly and assembly of the nib 2 more convenient. When the nib 2 is damaged after long-term use of the capacitive pen, it is convenient for the user to replace the nib 2. An annular groove 24 is provided at the lower end of the outer wall of the fixing block 21. After the nib 2 is installed at the lower end of the pen shaft 1, the lower end of the inner wall of the pen shaft 1 will be snap-fitted with the annular groove 24, which can provide a better fixing effect on the nib 2, thereby making the nib 2 more stable after installation. A protective shell 3 for protecting the nib 2 is slidably connected to the lower end of the outer wall of the pen shaft 1. When the capacitive pen is not needed, the nib 2 can be wrapped inside by the protective shell 3, so as to play a better protective role for the nib 2. A guide block 25 is fixedly connected to the inner wall of the protective shell 3. A guide groove 26 matching the guide block 25 is provided on the outer wall of the pen shaft 1, which can play a better limiting and guiding role for the protective shell 3, so that the protective shell 3 can only slide in the vertical direction of the pen shaft 1, thereby making the protective shell 3 more stable when sliding up and down. A rubber sleeve 30 is sleeved on the outer wall of the protective shell 3, which can make the user's hand more comfortable when holding the pen. Anti-slip lines are provided on the outer wall of the rubber sleeve 30, which can increase the friction between the user's hand and the capacitive pen, thereby effectively preventing the user's hand from slipping when holding the pen. A rubber skin 28 is fixedly connected to the bottom of the inner wall of the protective shell 3. A cross groove 29 is provided on the rubber skin 28. After the protective shell 3 wraps the nib 2 inside, a better dust-proof effect can be achieved through the rubber skin 28, so as to play a better protective effect on the nib 2. A limiting component for fixing the protective shell 3 is provided on the outer wall of the pen shaft 1. The protective shell 3 can be fixed through the limiting component, thereby effectively ensuring the normal use of the capacitive pen. A main board 4 is fixedly installed at the bottom of the inner wall of the pen shaft 1. A Bluetooth module 5, a data processing module 6 and a timing module 27 are fixedly installed on the main board 4. A battery 7 is fixedly installed above the main board 4 inside the pen shaft 1. An inclination sensor 8 is fixedly installed above the battery 7 inside the pen shaft 1. An installation block 9 is fixedly connected above the inclination sensor 8 inside the pen shaft 1. Symmetrical speakers 10 are fixedly installed on the installation block 9. A plurality of through holes 11 matching the speakers 10 are provided on the outer wall of the pen shaft 1, and the through holes 11 are linearly arrayed and equally spaced on the pen shaft 1. Through the inclination sensor 8 provided inside the pen shaft 1, if the user's pen-holding posture is incorrect, the inclination sensor 8 will send an electrical signal to the data processing module 6. After the data processing module 6 analyzes and processes the data, it will send an electrical signal to the speaker 10. After receiving the electrical signal, the speaker 10 will emit a voice reminder to remind the user to correct the pen-holding posture in time. When the user uses the capacitive pen for a long time,The timing module 27 also sends an electrical signal to the speaker 10. After receiving the electrical signal, the speaker 10 will issue a voice reminder. An upper end of an outer wall of the pen barrel 1 is provided with a charging interface 12 for charging the battery 7. The battery 7 inside the capacitive pen can be charged through the charging interface 12 provided at the upper end of the pen barrel 1. An upper end of the outer wall of the pen barrel 1 above the charging interface 12 is fixedly connected with a protection component for protecting the charging interface 12. After charging, the protection component can play a good role in protecting the charging interface 12, thereby effectively preventing a large amount of dust from entering the charging interface 12 and damaging the capacitive pen, and further effectively extending the service life of the capacitive pen.

[0039] As Figure 4 and Figure 8 shown, the limiting component includes sliding cavities 13 opened on the outer wall of the pen barrel 1, and the sliding cavities 13 are symmetrically arranged on the pen barrel 1. The inside of each sliding cavity 13 is slidably connected with a limiting block 14. One end of the limiting block 14 extends out of the sliding cavity 13, and the other end is fixedly connected with a spring 15. One end of the limiting block 14 extending out of the sliding cavity 13 is rotatably connected with a ball 31. The other end of the spring 15 is fixedly connected with the inner wall of the sliding cavity 13. An upper end of the outer wall of the protective shell 3 is provided with a limiting groove 16 matching the limiting block 14. The inner wall of the limiting groove 16 is fixedly connected with a button 17. One end of the button 17 extends out of the limiting groove 16, and the other end abuts against the limiting block 14. The button 17 can be made of rubber material. Since the rubber material is relatively soft, the limiting block 14 can be moved by pressing the button 17. When the capacitive pen is in use, by pressing the button 17, the limiting block 14 can be pushed to slide into the sliding cavity 13. When the limiting block 14 disengages from the limiting groove 16 on the protective shell 3, the protective shell 3 can be slid upward to expose the pen tip 2. Press the limiting block 14 inside the sliding cavity 13 above the pen barrel 1 to make it enter the sliding cavity 13, and then continue to slide the protective shell 3 upward to a certain extent. The limiting block 14 inside the sliding cavity 13 above the pen barrel 1 will pop out under the action of the spring 15 and be clamped with the limiting groove 16, and the capacitive pen can be used normally. After the capacitive pen is used, press the button 17 to make the limiting block 14 inside the sliding cavity 13 above the pen barrel 1 disengage from the limiting groove 16, and then slide the protective shell 3 downward. When the pen tip 2 completely enters the protective shell 3, the limiting block 14 inside the sliding cavity 13 below the pen barrel 1 will pop out under the action of the spring 15 and be clamped with the limiting groove 16. At this time, the protective shell 3 can play a good role in protecting the pen tip 2, thereby effectively extending the service life of the capacitive pen.

[0040] As Figure 2As shown in the figure, the protection component includes a rubber strip 18 fixedly connected to the upper end of the outer wall of the pen shaft 1 above the charging interface 12. One end of the rubber strip 18 away from the pen shaft 1 is fixedly connected to a rubber cover 19. The bottom of the rubber cover 19 is fixedly connected to a dust-proof plug 20 that matches the charging interface 12. After the capacitive pen is charged, pull the rubber cover 19 to insert the dust-proof plug 20 at its bottom into the charging interface 12, which can effectively prevent a large amount of dust from entering the charging interface 12 and damaging the capacitive pen, thereby further effectively extending the service life of the capacitive pen.

[0041] As can be seen from the above, the specific implementation manner of the present invention is as follows:

[0042] When using this capacitive pen, insert one end of the charger into the charging interface 12, and then connect the charger to the power supply to charge the battery 7 inside the pen shaft 1. The charging interface 12 is a Type-c interface, which is applicable to most chargers on the market. After the battery 7 is fully charged, unplug the charging cable. Press the button 17 to push the limiting block 14 to slide into the sliding cavity 13. When the limiting block 14 disengages from the limiting groove 16 on the protective shell 3, the protective shell 3 can be slid upward to expose the pen tip 2. Press the limiting block 14 inside the sliding cavity 13 above the pen shaft 1 to make it enter the sliding cavity 13, and then continue to slide the protective shell 3 upward to a certain extent. The limiting block 14 inside the sliding cavity 13 above the pen shaft 1 will pop out under the action of the spring 15 and engage with the limiting groove 16, which can play a good fixing role for the protective shell 3. At this time, bring the capacitive pen close to the electronic device, and the Bluetooth module 5 on the main board 4 inside the pen shaft 1 will automatically match and connect with the electronic device. When the connection is successfully displayed on the electronic device, the capacitive pen can be used normally. During the use of the capacitive pen, the inclination sensor 8 detects the inclination characteristics of the pen shaft 1. After the inclination sensor 8 detects the inclination characteristics of the pen shaft 1, it will send an electrical signal to the data processing module 6 on the main board 4. The data processing module 6 analyzes and processes the data. If the user's pen-holding posture is correct, the capacitive pen can be used normally. If the user's pen-holding posture is incorrect, the data processing module 6 will send an electrical signal to the speaker 10. After receiving the electrical signal, the speaker 10 will emit a voice reminder to remind the user to correct the pen-holding posture in time. When the user uses the capacitive pen for a long time, the timing module 27 will also send an electrical signal to the speaker 10. After receiving the electrical signal, the speaker 10 will emit a voice reminder, which can effectively prevent the user from getting tired due to long-term use of the capacitive pen. After the use of the capacitive pen is completed, press the button 17 to make the limiting block 14 inside the sliding cavity 13 above the pen shaft 1 disengage from the limiting groove 16, and then slide the protective shell 3 downward. When the pen tip 2 completely enters the protective shell 3, the limiting block 14 inside the sliding cavity 13 below the pen shaft 1 will pop out under the action of the spring 15 and engage with the limiting groove 16. At this time, the protective shell 3 can play a good protection role for the pen tip 2, thereby effectively extending the service life of the capacitive pen.

[0043] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.

After the inclination sensor (8) detects the inclination characteristics of the pen holder (1), it sends an electrical signal to the data processing module (6) on the main board (4); D: The data processing module (6) analyzes and processes the data. If the user holds the pen in a correct posture, the capacitive pen can be used normally. If the user holds the pen in an incorrect posture, the data processing module (6) sends an electrical signal to the speaker (10). After receiving the electrical signal, the speaker (10) issues a voice reminder, thereby reminding the user to correct the pen holding posture in a timely manner.
