Detailed Description
The present application is described in further detail below with reference to figures 1-4.
The embodiment of the application discloses a posture correcting pen for correcting a pen holding mode and a sitting posture. Referring to fig. 1 and 2, the posture correcting pen for correcting the pen holding mode and the sitting posture comprises a pen shell 1, wherein the pen shell 1 comprises a first shell 11 and a second shell 12, the first shell 11 and the second shell 12 are both hollow cylinders, one end of the first shell 11 is a hollow cone, the other end of the first shell 11 is detachably connected with one end of the second shell 12, and a pen core 5 is arranged in the first shell 11 in a penetrating mode along the length direction of the first shell 11.

One end of the second shell 12 far away from the first shell 11 is penetrated and connected with a pen cap 3 in a sliding way, and the opening and closing of the posture correcting module 2 can be controlled by pressing the pen cap 3. The outer side wall of the second shell 12 is fixedly connected with a pen clip 4.
Referring to fig. 3 and 4, the posture correcting module 2 includes a power supply unit 26, the power supply unit 26 may be a battery pack, and the power supply unit 26 is fixedly connected to one side of the inner side wall of the second housing 12. The power supply unit 26 is electrically connected to a power switch 27, the power switch 27 is a button switch, the power switch 27 is fixedly connected to one end of the second housing 12 close to the cap 3, and a button of the power switch 27 faces the cap 3. The posture correcting module 2 further comprises a distance measuring unit 21, the distance measuring unit 21 can be an infrared detector, the distance measuring unit 21 is fixedly connected to the position, close to the window 121, in the second shell 12, and the distance measuring unit 21 detects the distance between the head of the user and the writing horizontal plane through the window 121 of the second shell 12. The posture correcting module 2 further includes a controller 23, the controller 23 may be a Micro Controller Unit (MCU), the controller 23 is fixedly connected to a position between the power switch 27 and the distance measuring Unit 21 in the second housing 12, the controller 23 is electrically connected to the distance measuring Unit 21, and the controller 23 may receive data information measured by the distance measuring Unit 21.
Referring to fig. 3 and 4, the posture correcting module 2 further includes an early warning unit 24, the early warning unit 24 is fixedly connected to an end of the second housing 12 far away from the cap 3, the early warning unit 24 is a vibrator, the early warning unit 24 is electrically connected to the controller 23, and the early warning unit 24 can start to generate vibration by receiving a control signal. A first distance threshold and a second distance threshold are preset in the controller 23, and the first distance threshold is smaller than the second distance threshold. The first distance threshold refers to the closest distance between the head of the user and the writing horizontal plane, the second distance threshold refers to the farthest distance between the head of the user and the writing horizontal plane, and the distance between the head of the user and the writing horizontal plane when the user sits correctly is the distance between the head of the user and the writing horizontal plane.
When the distance between the head of the user and the writing horizontal plane detected by the distance measuring unit 21 is smaller than the first distance threshold or larger than the second distance threshold, the controller 23 outputs a first early warning signal to the early warning unit 24, and the early warning unit 24 receives the first early warning signal and starts to generate vibration in response to the first early warning signal, so as to remind the user to correct the sitting posture through the vibration.
For example, if the first distance threshold is preset to 30CM and the second distance threshold is preset to 40CM, if the distance measuring unit 21 detects that the distance between the head of the user and the writing horizontal plane is 25CM, and the sitting posture of the user may be in a humpback state at this time, the controller 23 will send out the first warning signal to make the warning unit 24 vibrate to remind the user to change the sitting posture; if the distance measuring unit 21 detects that the distance between the head of the user and the writing horizontal plane is 35CM, the controller 23 does not output the first early warning signal; if the distance measuring unit 21 detects that the distance between the head of the user and the writing horizontal plane is 42CM, and the sitting posture of the user may be in a backward leaning state, the controller 23 will send out the first warning signal to make the warning unit 24 vibrate to remind the user to change the sitting posture.
Referring to fig. 3 and 4, the posture correcting module 2 further includes an angle measuring unit 22, the angle measuring unit 22 is fixedly connected to a position on the right side of the early warning unit 24 in the second housing 12, and the angle measuring unit 22 is electrically connected to the controller 23.
The angle measuring unit 22 is a triaxial accelerometer, which can detect an inertial force vector applied to the gesture correcting pen in a three-dimensional space, measure analog data of acceleration of the vector in a triaxial direction, and convert the analog data into a voltage value. The triaxial accelerometer is provided with initial sensitivity, and the measured voltage value is introduced into the sensitivity of the triaxial accelerometer for calculation, so that the acceleration of the posture correcting pen in the triaxial direction in space can be obtained. The vector components of the inertia force vector on three axes can be obtained according to the acceleration in the three axis directions, and then the included angle between the inertia force vector and the axial component of the horizontal plane is calculated through the trigonometric function theorem, so that the angle value between the posture correcting pen and the writing horizontal plane can be obtained.
The angle measuring unit 22 outputs the detected angle measurement data to the controller 23, and a second angle threshold value is preset in the controller 23, and the second angle threshold value is 45 ° or less. When a person normally writes, if the pen holding mode is correct, the included angle between the pen shell 1 and the writing horizontal plane ranges from 45 degrees to 60 degrees, and the second angle threshold value refers to the minimum included angle between the pen shell 1 and the writing horizontal plane when the pen holding mode is correct, so that the second angle threshold value can be set to 45 degrees. If the angle measuring unit 22 detects that the included angle between the pen casing 1 and the writing horizontal plane is smaller than the second angle threshold, the controller 23 outputs a second warning signal to the warning unit 24, and the warning unit 24 receives the second warning signal, responds to the second warning signal, and starts to generate vibration.
In another embodiment, a third angle threshold may be preset in the controller 23, and the third angle threshold may be preset to 60 °, if the angle measuring unit 22 detects that the angle between the pen casing 1 and the writing horizontal plane exceeds the third angle threshold, the controller 23 will output a second warning signal to the warning unit 24, and the warning unit 24, upon receiving the second warning signal, will respond to the second warning signal and start generating vibration.
Referring to fig. 3 and 4, the posture correcting module 2 further includes a delay unit 25, and the delay unit 25 is fixedly connected to a position between the angle measuring unit 22 and the early warning unit 24 in the second housing 12. The delay unit 25 is electrically connected with the controller 23 and the early warning unit 24, the angle measuring unit 22 outputs the detected angle to the controller 23, the controller 23 compares the angle with a second angle threshold, and if the angle exceeds the second angle threshold, a second early warning signal is output to the delay unit 25. A first delay time is preset in the delay unit 25, and if the time for the delay unit 25 to receive the second warning signal exceeds the first delay time, the delay unit 25 outputs the second warning signal to the warning unit 24 to send a vibration warning.
For example, if the first delay time preset in the delay unit 25 is 2S, the second angle threshold is 45 °, the angle detection unit detects that the angle between the pen casing 1 and the writing horizontal plane is 50 ° and continues for 0.5S, at this time, the user may be writing a special character in a correct pen holding manner, and the angle between the pen casing 1 and the writing horizontal plane is just 50 ° during the process of writing a certain stroke. The controller 23 outputs the second warning signal of 0.5S to the delay unit 25 at this time, and since the duration of the second warning signal is less than 2S, the delay unit 25 does not output the second warning signal to the warning unit 24. Through the arrangement of the time delay unit 25, the condition that the early warning unit 24 gives out false warning due to part of special time when a user writes in a normal pen holding mode can be avoided.
A first angle threshold is also preset in the controller 23, the first angle threshold is smaller than the second angle threshold and larger than 0 °, and the first angle threshold may be preset to 20 °. When the angle measuring unit 22 detects that the angle between the pen casing 1 and the writing horizontal plane is smaller than the first angle threshold, the controller 23 outputs a third early warning signal to the delay unit 25, a second delay time is preset in the delay unit 25, and if the time of the delay unit 25 receiving the third angle threshold exceeds the second delay time, the delay unit 25 outputs the third early warning signal to the early warning unit 24.
For example, assuming that the second delay time preset in the delay unit 25 is 3S, the first angle threshold is 20 °, and the angle measuring unit 22 detects that the angle between the pen casing 1 and the writing horizontal plane is between 5 ° and 10 ° and lasts for more than 3S, the user may play the posture correcting pen while the power switch 27 is turned on. The controller 23 outputs a third warning signal of more than 3S to the delay unit 25 at this time, and since the duration of the third warning signal is greater than 3S, the delay unit 25 outputs the third warning signal to the warning unit 24, and the warning unit 24 receives the third warning signal and starts to generate vibration in response to the third warning signal, so as to remind the user to turn off the power switch 27 or stop playing.
Referring to fig. 3 and 3, the posture correcting module 2 further includes an automatic power-off unit 28, the automatic power-off unit 28 is fixedly connected to a position between the power switch 27 and the controller 23 in the second housing 12, the automatic power-off unit 28 is electrically connected to the power switch 27 and the controller 23, respectively, and the automatic power-off unit 28 is further electrically connected to the delay unit 25. A third delay time is preset in the delay unit 25, when the angle measuring unit 22 detects that the angle between the pen casing 1 and the writing horizontal plane is 0 °, the controller 23 outputs a power-off signal to the delay unit 25, if the time for the delay unit 25 to receive the power-off signal exceeds the third delay time, the delay unit 25 outputs the power-off signal to the automatic power-off unit 28, and the automatic power-off unit 28 receives the power-off signal and responds to the power-off signal to cut off the power supply of the controller 23, and resets the power switch 27.
For example, assuming that the third delay time is 30S, the angle measuring unit 22 detects that the angle between the pen casing 1 and the horizontal writing surface is 0 ° and continues for 32S, and the user may forget to turn off the power switch 27 when the user uses the pen in the correct posture and lies flat on the desktop. The controller 23 outputs a 32S power-off signal to the delay unit 25 at this time, and since the duration of the power-off signal exceeds 30S, the delay unit 25 outputs the power-off signal to the auto-power-off unit 28, and the auto-power-off unit 28 receives the power-off signal, cuts off the power supplied to the controller 23, and resets the power switch 27. Through the arrangement of the automatic power-off unit 28, when a user places the posture correcting pen on the horizontal table and forgets to turn off the power switch 27, the controller 23 can be automatically powered off, so that the electric energy in the power supply unit 26 can be saved, and the service life of the whole posture correcting module 2 can be prolonged.
The implementation principle of the posture correcting pen for correcting the pen holding mode and the sitting posture in the embodiment of the application is as follows:
when a user writes by using the posture correcting pen, the user can press the pen cap 3 to turn on the power switch 27, at the moment, the distance measuring unit 21 in the posture correcting module 2 detects the distance between the head of the user and a writing horizontal plane in real time, the angle measuring unit 22 in the posture correcting module 2 detects the angle between the pen shell 1 and the writing horizontal plane in real time, and if the detected distance exceeds a threshold value in the controller 23, the controller 23 controls the early warning unit 24 to vibrate to remind the user to adjust the sitting posture; if the detected angle exceeds the threshold value in the controller 23 for a period of time, the controller 23 will also control the early warning unit 24 to vibrate to remind the user to adjust the pen holding mode. When the posture correcting pen is not needed to be used, the pen cap 3 is pressed down again to turn off the power switch 27, and the posture correcting pen can be stored.
