Description

Technical Field

[0001] The present invention relates to the technical field of capacitive pens, in particular to a capacitive pen capable of correcting writing posture and a control method thereof. Background Art

[0002] Capacitive pen is also a stylus, which can be used in enterprise OA, ERP system, collaborative system or professional organization intranet. Its appearance can facilitate people's use. It is not only simple in structure, but also easy to operate. With the popularization of electronic products, the use of Bluetooth capacitive pen with electronic devices such as tablets is becoming more and more extensive. Usually, before using Bluetooth capacitive pen with electronic devices for writing and drawing, you need to pair the Bluetooth capacitive pen with the electronic device and establish a Bluetooth connection;

[0003] However, the pen tip of the current capacitive stylus is exposed to the outside, and the exposed pen tip is easily damaged by external impact, thereby affecting the service life of the capacitive stylus. In addition, the current capacitive stylus cannot correct the user's writing posture when in use. If the user holds the pen in an incorrect posture for a long time, it will not only affect the writing effect, but also endanger the health of the body, causing myopia, strabismus and spinal curvature.

[0004] In order to solve the above problems, the present application proposes a capacitive pen capable of correcting writing posture and a control method thereof. Summary of the invention

[0005] The present invention aims to provide a capacitive pen capable of correcting writing posture and a control method thereof, which is mainly used to solve the problem that the tip of the existing capacitive pen is exposed to the outside and is easily damaged, thereby affecting the service life of the capacitive pen. In addition, the current capacitive pen cannot correct the user's writing posture when in use, which not only affects the writing effect, but also may cause the user to have problems such as myopia, strabismus and spinal curvature.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] A capacitive pen capable of correcting writing posture comprises a pen holder, a cavity is formed at the lower end of the pen holder, a movable column is slidably connected inside the cavity, a pen tip is connected to the lower end of the movable column, a driving component for moving the movable column is fixedly installed above the movable column inside the cavity, a battery is fixedly installed above the driving component inside the cavity, a charging interface is provided at the upper end of the pen holder, a protective component for protecting the charging interface is fixedly connected to the upper end of the outer wall of the pen holder, a first indicator light is fixedly installed at the upper end of the outer wall of the pen holder, a button is installed on the outer wall of the pen holder below the first indicator light, the first indicator light and the button are electrically connected to the battery inside the pen holder, and a pen holding information collection component is fixedly connected to the lower end of the outer wall of the pen holder.

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

[0009] 1. Working principle: When using the 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. The charging interface is a Type-c interface, which can be used for most chargers on the market. After the battery is fully charged, unplug the charging cable, press the button to drive the pen tip downward through the driving component, so that the pen tip is completely extended out of the cavity. When using the capacitive pen, the user holds the pen holding information collection component on the pen holder with his hand, and sends an electrical signal to the first indicator light through the pen holding information collection component. If the first indicator light is red, it means that the user's pen holding posture is wrong, and the user needs to adjust the pen holding posture. If the first indicator light is green, it means that the user's pen holding posture is correct, and the capacitive pen can be used normally.

[0010] 2. Beneficial effects:

[0011] (1) The driving component can be used to drive the pen tip to move up and down. When the capacitive pen is not in use, the pen tip can be stored in the cavity, which can effectively prevent the pen tip from being exposed for a long time, thereby providing better protection for the pen tip and effectively extending the service life of the capacitive pen.

[0012] (2) The capacitive pen can be charged through the charging interface provided at the upper end of the pen holder. After charging, the protective component can provide good protection for the charging interface, thereby effectively preventing a large amount of dust from entering the charging interface and causing damage to the capacitive pen, thereby effectively extending the service life of the capacitive pen;

[0013] (3) Through the pen-holding information collection component arranged at the lower end of the outer wall of the pen shaft, when the user holds the pen in an incorrect posture, the pen-holding information collection component will send an electrical signal to the first indicator light and make it emit red light, thereby reminding the user to adjust the pen-holding posture. After the user's pen-holding posture is correct, the first indicator light turns green and the capacitive pen can be used normally. The advantage of such a setting is that the user's writing posture can be corrected when the capacitive pen is used.

[0014] Preferably, the driving assembly includes a micromotor fixedly installed below the battery inside the cavity, a threaded rod fixedly connected to the output end of the micromotor, a threaded groove matching the threaded rod opened at the upper end of the movable column, the lower end of the threaded rod extends to the inside of the threaded groove and is threadedly connected to the inner wall of the threaded groove, the micromotor is electrically connected to the battery inside the pen barrel, the battery can be used to power the micromotor by pressing a button, the threaded rod can be rotated by the operation of the micromotor, and the rotation of the threaded rod can cause the movable column threadedly connected thereto to drive the pen tip to move downward, so that the pen tip is completely extended out of the cavity, the micromotor is a servo motor, and the micromotor stops operating after the pen tip is completely extended out of the cavity, and the capacitive pen can be used normally, and after the capacitive pen is used, the micromotor is controlled to cause the threaded rod to rotate in the opposite direction, so that the movable column can drive the pen tip to move upward, thereby storing the pen tip inside the cavity, which can effectively prevent the pen tip from being exposed to the outside for a long time, thereby providing better protection for the pen tip, and thus effectively extending the service life of the capacitive pen.

[0015] Preferably, the protective component includes a rubber strip fixedly connected to the upper end of the outer wall of the pen shaft, one end of the rubber strip is fixedly connected to a rubber cover, and the bottom of the rubber cover is fixedly connected to a rubber plug matching the charging interface. After the capacitive pen is charged, the rubber cover is rotated to insert the rubber plug at the bottom of the rubber cover into the charging interface. This can effectively prevent a large amount of dust from entering the charging interface and causing damage to the capacitive pen, thereby effectively extending the service life of the capacitive pen.

[0016] Preferably, the pen holding information collection component includes a fixed shell fixedly connected to the lower end of the outer wall of the pen shaft, and a plurality of pressure sensors are fixedly installed inside the fixed shell, and the pressure sensors are evenly distributed in an array inside the fixed shell. When the capacitive pen is used, the user holds the pen holding information collection component on the pen shaft with his hand. The pen holding information collection component includes the fixed shell and the pressure sensor. The pressure sensor will send an electrical signal to the first indicator light when it is subjected to pressure. If the first indicator light is red, it means that the user's pen holding posture is wrong, and the user needs to adjust the pen holding posture. If the first indicator light is green, it means that the user's pen holding posture is correct, so that the user's writing posture can be corrected when the capacitive pen is used.

[0017] Preferably, the top of the pen tip is fixedly connected with a threaded barrel, the lower end of the movable column is fixedly connected with a threaded column matching the threaded barrel, the threaded column is threadedly connected to the inner wall of the threaded barrel, and the pen tip is threadedly connected to the lower end of the movable column. This not only makes the connection between the pen tip and the movable column more secure, but also makes the disassembly and assembly of the pen tip more convenient. This makes it convenient for people to replace the pen tip when the pen tip is damaged after long-term use.

[0018] Preferably, a tilt sensor is fixedly installed inside the pen body above the battery, and a second indicator light is fixedly installed on the outer wall of the pen body between the first indicator light and the button. The tilt sensor is electrically connected to the second indicator light. When the capacitive pen is in use, the tilt angle of the capacitive pen can be sensed by the tilt sensor. When the tilt angle of the capacitive pen is too large, the second indicator light is displayed as red. If the tilt angle of the capacitive pen is appropriate, the second indicator light is displayed as green, and the capacitive pen can be used normally.

[0019] Preferably, a symmetrical guide block is fixedly connected to the upper end of the outer wall of the moving column, and a guide groove matching the guide block is provided on the inner wall of the cavity. When the moving column slides inside the cavity, the guide block provided on the moving column and the guide groove provided on the inner wall of the cavity can play a better limiting and guiding role for the moving column, so that the moving column can only slide in the vertical direction inside the cavity, and can effectively prevent the moving column from escaping from the inside of the cavity, thereby effectively ensuring the normal use of the capacitive stylus.

[0020] Preferably, the outer wall of the fixed shell is provided with a rubber sleeve, and the rubber sleeve is provided with anti-slip grooves. The rubber sleeve provided on the outer wall of the fixed shell can make the user's hand more comfortable when holding the pen holding information collection component on the pen shaft and using the capacitive pen. The rubber sleeve is provided with anti-slip grooves, which can effectively prevent the user's hand from slipping when holding the capacitive pen, thereby making the use of the capacitive pen more convenient.

[0021] A control method for a capacitive pen capable of correcting writing posture comprises the following steps:

[0022] A: Insert one end of the charger into the charging port, and then connect the charger to the power supply to charge the battery inside the pen. After the battery is fully charged, unplug the charging cable and the capacitive pen can be used normally.

[0023] B: By pressing the button, the battery inside the pen barrel can power the micro motor, and the micro motor can rotate the threaded rod. The rotation of the threaded rod can cause the moving column threadedly connected to it to drive the pen tip to move downward, so that the pen tip is completely extended out of the cavity;

[0024] C: When the capacitive pen is used, the user holds the pen holding information collection component on the pen holder, and the pen holding information collection component includes a fixed shell and a pressure sensor. When the pressure sensor is subjected to pressure, an electrical signal is generated to the first indicator light. If the first indicator light is red, it means that the user's pen holding posture is wrong, and the user needs to adjust the pen holding posture. If the first indicator light is green, it means that the user's pen holding posture is correct.

[0025] D: When the capacitive pen is in use, the tilt sensor can sense the tilt angle of the capacitive pen. When the tilt angle of the capacitive pen is too large, the second indicator light turns red. If the tilt angle of the capacitive pen is appropriate, the second indicator light turns green and the capacitive pen can be used normally. BRIEF DESCRIPTION OF THE DRAWINGS

A driving component for moving the moving column 3 is fixedly installed above the moving column 3 inside the cavity 2, and the moving column 3 can drive the pen tip 4 to move up and down through the operation of the driving component.

The pen holding information collection component includes a fixed shell 15 and a pressure sensor 16. When the pressure sensor 16 is subjected to pressure, it will send an electrical signal to the first indicator light 7. If the first indicator light 7 displays a red light, it means that the user's pen-holding posture is wrong, and the user needs to adjust the pen-holding posture. If the first indicator light 7 displays a green light, it means that the user's pen-holding posture is correct. When the capacitive pen is in use, the inclination angle of the capacitive pen can be sensed by the inclination sensor 21. When the inclination angle of the capacitive pen is too large, the second indicator light 23 displays a red light. If the inclination angle of the capacitive pen is appropriate, the second indicator light 23 displays a green light. In this way, the user's writing posture can be corrected when the capacitive pen is in use. After the capacitive pen is used, the micro motor 9 is controlled to make the threaded rod 10 rotate in the opposite direction, so that the movable column 3 can drive the pen tip 4 to move upward, thereby storing the pen tip 4 in the cavity 2.
