Description

Technical Field

[0001] This invention relates to the field of stationery technology, and in particular to a notebook anti-tilt positioning clip with tilt angle monitoring and reminder function. Background Technology

[0002] During students' daily writing process, the angle at which their notebooks are placed directly affects the standardization of their writing posture, which in turn relates to their vision health and spinal development. Currently, most students lack effective control over the angle of their notebooks when writing, and their notebooks are prone to tilting to the left or right. Maintaining such poor writing habits for a long time can lead to distorted sitting posture, skewed vision, and increase the risk of problems such as myopia and scoliosis. In existing technologies, stationery for positioning exercise books is mostly limited to ordinary clips and positioning rulers, which only have simple fixing or limiting functions and cannot monitor and remind users of the tilt angle of the exercise book in real time. While some posture correction devices can help regulate posture, they do not control the crucial factor of the exercise book's placement angle, making it difficult to address the writing problems caused by the exercise book's tilt at the source. Furthermore, some angle monitoring devices are complex in structure and bulky, unsuitable for students' daily writing scenarios, and suffer from insufficient sensitivity, susceptibility to environmental interference, and inability to adaptively adjust according to user habits, resulting in poor practicality. Therefore, to better solve the above problems, this invention proposes an anti-tilt positioning clip for exercise books with tilt angle monitoring and reminder functions. Summary of the Invention

[0003] In response to the above situation, this invention proposes a notebook anti-tilt positioning clip with tilt angle monitoring and reminder function. 1. It includes a positioning clip body, an automatic tilt angle testing system, a control module, a reminder module, a power supply module, and adjustment buttons. The purpose of this invention is to achieve real-time and accurate monitoring and automatic reminder of the tilt angle of the notebook, while also being lightweight, easy to operate, and highly adaptable, thus meeting the daily writing needs of students. A notebook anti-tilt positioning clip with tilt angle monitoring and reminder function includes a positioning clip body, an automatic tilt angle testing system, a control module, a reminder module, a power supply module, and adjustment buttons; The positioning clamp body includes a fixed base and a clamping assembly. The clamping assembly is installed on one side of the fixed base, and the adjustment button is embedded in the surface of the fixed base. The automatic tilt angle testing system is integrated inside the fixed base. The automatic tilt angle testing system uses a combination of a triaxial accelerometer and a gravity vector calibration algorithm. The detection plane of the automatic tilt angle testing system is parallel to the upper surface of the fixed base and fits the placement plane of the clamped workbook. By collecting the component signals of gravity in the X and Y axes in real time, the system eliminates environmental vibration interference through the built-in filtering algorithm of the control module and calculates the left and right tilt angle data of the workbook. The gravity vector calibration algorithm performs zero-point calibration and temperature drift compensation on the gravity component signals collected by the sensor in real time through the microcontroller of the control module. The control module is electrically connected to the tilt angle automatic testing system, the reminder module, the power supply module and the adjustment button respectively. The control module includes a microcontroller and a storage unit. The storage unit pre-stores the tilt angle threshold. The microcontroller adopts a dynamic adaptive threshold comparison algorithm. After receiving the angle data, it can automatically optimize the threshold judgment window according to the tilt fluctuation pattern during the user's writing process. When the detected tilt angle exceeds the preset threshold, the control module immediately sends a trigger signal to the reminder module. The reminder module responds to the trigger signal of the control module and sends a reminder message to alert the user to adjust the angle of the exercise book. The power supply module provides operating power to the tilt angle automatic testing system, the control module, and the reminder module. Furthermore, the clamping assembly includes a first clamping plate, a second clamping plate, and an elastic connector. The first clamping plate is fixedly connected to the fixed base, and the second clamping plate is connected to the first clamping plate through the elastic connector. The first clamping plate and the second clamping plate are arranged opposite to each other to form a clamping cavity. The elastic connector provides clamping force to clamp the two clamping plates tightly between the edge of the exercise book and the edge of the desktop. Furthermore, both the clamping surfaces of the first clamping plate and the second clamping plate are provided with anti-slip buffer pads, which are made of silicone material and have anti-slip textures on their surfaces; Furthermore, the adjustment button is used for the user to manually trigger threshold calibration and adjust the volume / blinking frequency of the reminder module. After the operation signal is transmitted to the control module, the control module executes the corresponding instruction and updates the storage unit parameters. Furthermore, the reminder module is an audio-visual reminder module, including a buzzer and an LED indicator. Both the buzzer and the LED indicator are mounted on the surface of the fixed base. When the tilt angle collected by the automatic tilt angle testing system exceeds the standard, the buzzer emits an alarm sound, and the LED indicator flashes synchronously. The volume of the alarm sound and the flashing frequency of the LED indicator can be triggered by the adjustment button, and the control module performs the adjustment and saves the parameters. Furthermore, the power supply module uses a rechargeable lithium battery, the mounting base has a battery compartment inside, the lithium battery is detachably installed in the battery compartment, the mounting base has a charging interface on its surface, the charging interface is connected to the lithium battery, and supports USB charging; Furthermore, the fixing base is made of lightweight ABS composite material, with a thickness of 8-15mm, a length of 50-100mm, and an overall weight of no more than 50g. Compared with the prior art, the significant advantages of this invention are: (1) Precise monitoring and intelligent reminders: This invention uses a triaxial accelerometer combined with a gravity vector calibration algorithm, along with a filtering algorithm and a dynamic adaptive threshold comparison algorithm, to collect the tilt angle data of the exercise book in real time and accurately, effectively eliminating environmental interference and equipment errors, avoiding false reminders, and providing dual reminders of sound and light when the angle exceeds the standard, guiding users to correct it in time, standardizing the angle of exercise book placement from the source, helping to develop good writing habits, and protecting vision and spinal health.

Specific embodiments The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. A notebook anti-tilt positioning clip with tilt angle monitoring and reminder function includes a positioning clip body, an automatic tilt angle testing system, a control module, a reminder module, a power supply module, and adjustment buttons; The positioning clamp body includes a fixed base 1 and a clamping assembly. The clamping assembly is installed on one side of the fixed base 1, and the adjustment button is embedded in the surface of the fixed base 1. The automatic tilt angle testing system is integrated inside the fixed base 1. The automatic tilt angle testing system uses a combination of a triaxial accelerometer and a gravity vector calibration algorithm. The detection plane of the automatic tilt angle testing system is parallel to the upper surface of the fixed base 1 and fits the placement plane of the clamped workbook. By collecting the component signals of gravity in the X and Y axes in real time, the system eliminates environmental vibration interference through the built-in filtering algorithm of the control module and calculates the left and right tilt angle data of the workbook. The gravity vector calibration algorithm performs zero-point calibration and temperature drift compensation on the gravity component signals collected by the sensor in real time through the microcontroller of the control module. The control module is electrically connected to the tilt angle automatic testing system, the reminder module, the power supply module and the adjustment button respectively. The control module includes a microcontroller and a storage unit. The storage unit pre-stores the tilt angle threshold. The microcontroller adopts a dynamic adaptive threshold comparison algorithm. After receiving the angle data, it can automatically optimize the threshold judgment window according to the tilt fluctuation pattern during the user's writing process. When the detected tilt angle exceeds the preset threshold, the control module immediately sends a trigger signal to the reminder module. The reminder module responds to the trigger signal of the control module and sends a reminder message to alert the user to adjust the angle of the exercise book. The power supply module provides operating power to the tilt angle automatic testing system, the control module, and the reminder module. In specific embodiments, such as Figure 1 As shown, the positioning clamp body includes a fixed base 1 and a clamping assembly. The clamping assembly is installed on one side of the fixed base 1, and the adjustment button is embedded in the surface of the fixed base 1. The fixed base 1 serves as the mounting carrier for each functional module and provides a stable placement reference for the workbook. The clamping assembly is used to fix the positioning clamp to the workbook and the edge of the desktop, ensuring that the monitoring reference is synchronized with the placement state of the workbook. In specific embodiments, such as Figure 2As shown, the automatic tilt angle testing system is integrated inside the fixed base 1. It uses a three-axis accelerometer, model MPU6050, whose detection plane is parallel to the upper surface of the fixed base 1 and conforms to the placement plane of the exercise book being held. The system collects the components of gravity in the X-axis (left-right direction) and Y-axis (front-back direction) in real time through the sensor. After the signals are transmitted to the control module 3, the built-in Kalman filter algorithm eliminates the slight vibration interference during writing and calculates the left-right tilt angle data of the exercise book. At the same time, the gravity vector calibration algorithm performs zero-point calibration on the gravity component signals collected by the sensor every 5 seconds through the microcontroller 31 of the control module, and performs temperature drift compensation simultaneously to ensure the accuracy of angle detection, with the error controlled within ±0.5°. In specific embodiments, such as Figure 2 As shown, the control module is electrically connected to the automatic tilt angle testing system, the reminder module, the power supply module, and the adjustment buttons. It includes a microcontroller and a storage unit. The storage unit pre-stores tilt angle thresholds to meet the angle control requirements under normal writing scenarios. The pre-stored tilt angle threshold is ±5 degrees within the reasonable writing angle range. The microcontroller uses a dynamic adaptive threshold comparison algorithm. After receiving angle data, it analyzes the tilt fluctuation pattern within 10 minutes of continuous writing and automatically optimizes the threshold judgment window: the window shrinks to ±4.5 degrees when the fluctuation amplitude is small, and expands to ±5.5 degrees when the fluctuation amplitude is large, avoiding false reminders. When the detected tilt angle exceeds the currently optimized threshold and the duration reaches 0.3 seconds, the microcontroller immediately sends a trigger signal to the reminder module. The reminder module responds to the trigger signal from the control module and sends a reminder message to alert the user to adjust the angle of the exercise book, ensuring that the user can promptly perceive and correct any angle deviation. The power supply module provides a stable power supply for the tilt angle automatic testing system, control module, and reminder module, ensuring the continuous normal operation of the device. Furthermore, the clamping assembly includes a first clamping plate 2, a second clamping plate 3, and an elastic connector 21. The first clamping plate 2 is fixedly connected to the fixed base 1, and the second clamping plate 3 is connected to the first clamping plate 2 through the elastic connector 21. The first clamping plate 2 and the second clamping plate 3 are arranged opposite to each other to form a clamping cavity. The elastic connector 21 provides clamping force to clamp the two clamping plates tightly between the edge of the exercise book and the edge of the desktop. Furthermore, both the clamping surfaces of the first clamping plate 2 and the second clamping plate 3 are provided with anti-slip buffer pads, which are made of silicone material and have anti-slip textures on their surfaces. In specific embodiments, such as Figure 1As shown, the clamping assembly includes a first clamping plate 2, a second clamping plate 3, and an elastic connector 21. The first clamping plate 2 is fixedly connected to the fixed base 1, and the second clamping plate 3 is connected to the first clamping plate 2 via the elastic connector 21. The two are arranged opposite each other to form a clamping cavity. The elastic connector 21 provides a continuous clamping force, enabling the two clamping plates to tightly clamp the edge of the exercise book and the edge of the desktop. This achieves both fixed positioning of the exercise book and ensures the relative position of the positioning clamp with respect to the exercise book and the desktop is stable, avoiding angle detection deviation due to loose positioning. Both the clamping surfaces of the first clamping plate 2 and the second clamping plate 3 are equipped with anti-slip buffer pads. The anti-slip buffer pads are made of silicone material, which has good flexibility and anti-slip performance. The anti-slip texture on its surface can further enhance the clamping friction and effectively prevent the exercise book or positioning clip from sliding. At the same time, the silicone material can prevent the clamping plates from causing indentation damage to the edges of the exercise book and protect the integrity of the exercise book. Furthermore, the adjustment button is used for the user to manually trigger threshold calibration and adjust the volume / blinking frequency of the reminder module. After the operation signal is transmitted to the control module, the control module executes the corresponding instruction and updates the storage unit parameters. In specific embodiments, such as Figure 1 As shown, the adjustment buttons allow users to manually trigger threshold calibration and adjust the volume / blinking frequency of the reminder module. After the operation signal is transmitted to the control module, the control module executes the corresponding instruction and updates the storage unit parameters. When the control module receives a trigger signal, the buzzer 4 emits an alarm sound at a frequency of 1kHz, and the LED indicator 5 flashes synchronously at a frequency of 1 time per second. There are three adjustment buttons: calibration button 11, volume adjustment button 12, and frequency adjustment button 13. Pressing the calibration button 11 triggers threshold recalibration. Pressing the volume adjustment button 12 switches between high, medium, and low volume levels, corresponding to decibel values ​​of 60dB, 45dB, and 30dB. Pressing the frequency adjustment button 13 switches between fast, medium, and slow flashing frequencies, corresponding to 2 times / second, 1 time / second, and 0.5 times / second. After the operation signal is transmitted to the microcontroller, the microcontroller executes the corresponding instruction and updates the storage unit parameters. Users can flexibly adjust the device parameters according to their writing habits, ambient noise levels, and other scenario requirements to improve the user experience. Furthermore, the reminder module is an audio-visual reminder module, including a buzzer 4 and an LED indicator 5. Both the buzzer 4 and the LED indicator 5 are mounted on the surface of the fixed base 1. When the tilt angle collected by the automatic tilt angle testing system exceeds the standard, the buzzer 4 emits an alarm sound, and the LED indicator 5 flashes synchronously. The volume of the alarm sound and the flashing frequency of the LED indicator 5 can be triggered by the adjustment button, and the control module performs the adjustment and saves the parameters. In specific embodiments, such as Figure 1As shown, the reminder module is an audio-visual reminder module, including a buzzer 4 and an LED indicator 5, both mounted on the surface of the mounting base 1, allowing users to quickly perceive the reminder signal. When the tilt angle collected by the automatic tilt angle testing system exceeds the standard, the buzzer 4 emits an alarm sound, and the LED indicator 5 flashes synchronously. This dual reminder method can effectively adapt to different environmental scenarios. Furthermore, the volume of the alarm sound and the flashing frequency of the LED indicator 5 can be triggered by adjustment buttons, and the control module executes the adjustment and saves the parameters to meet personalized needs. Furthermore, the power supply module uses a rechargeable lithium battery, the mounting base 1 has a battery compartment inside, the lithium battery is detachably installed in the battery compartment, the mounting base 1 has a charging interface 6 on its surface, the charging interface 6 is connected to the lithium battery, and supports USB charging; In a specific embodiment, the power supply module uses a rechargeable lithium battery.

It is suitable for daily charging scenarios, eliminates the need for frequent replacement of disposable batteries, is more energy-efficient and environmentally friendly, and has a strong battery life to meet long-term use needs. Furthermore, the fixing base 1 is made of lightweight ABS composite material, the thickness of the fixing base 1 is 8-15mm, the length is 50-100mm, and the overall weight does not exceed 50g. In specific embodiments, such as Figure 1 As shown, the mounting base 1 is made of lightweight ABS composite material, which is lightweight, high-strength, wear-resistant and drop-resistant. Its thickness is 8-15mm, its length is 50-100mm, and its overall weight does not exceed 50g. It is small and portable, and will not bring extra burden to students' writing. It is suitable for daily storage scenarios such as school bags and pencil cases, and is easy to carry and use. The working principle of this invention is as follows: In use, the positioning clip is clamped to the edge of the workbook and the edge of the desktop using the clamping component, ensuring that the upper surface of the fixing base 1 is in contact with the plane where the workbook is placed. The device is powered on, and the automatic tilt angle testing system starts and begins to collect gravity component signals. After calibration, filtering, and conversion, the tilt angle data is obtained and transmitted to the control module. The control module uses a dynamic adaptive threshold comparison algorithm to determine whether the angle exceeds the standard. If it does, the reminder module is triggered to issue an audible and visual reminder. After receiving the reminder, the user adjusts the angle of the workbook. Once the angle returns to a reasonable range, the reminder automatically stops. Users can adjust the parameters by adjusting the buttons according to their own needs to adapt to different writing scenarios.
