Description
Technical Field
[0001] The utility model relates to the technical field of point reading pens, and specifically relates to an automatic wake-up system for a point reading pen. Background Technique
[0002] A point reading pen is an electronic device widely used in the fields of education and entertainment, which plays corresponding audio or video content by recognizing special printed marks or barcodes. With the progress of technology, the functions of point reading pens are becoming increasingly rich, but at the same time, they also face challenges in energy consumption management and user experience.
[0003] Currently, the on-off methods of traditional point reading pens mainly include the following: 1. Manual wake-up: Most point reading pens require users to manually press a physical button to wake up the device. Although this is simple and reliable, it reduces the convenience of use to a certain extent; 2. Mechanical switch: Some advanced models of point reading pens use mechanical switches to detect users' usage behaviors, and trigger the on-off of the circuit through mechanical actions to achieve the automatic wake-up function; 3. Acceleration sensor: Some point reading pens introduce acceleration sensors to detect the motion state of the point reading pen, so as to achieve the automatic wake-up function. For the first two methods, although they are simple, they are not intuitive enough for child users and cannot provide instant feedback. The third method usually requires complex sensor and circuit designs, which will increase the cost of the product. Content of the Utility Model
[0004] The purpose of the utility model is to provide an automatic wake-up system for a point reading pen to solve the problems raised in the above background technique.
[0005] To achieve the above purpose, the present disclosure provides an automatic wake-up system for a point reading pen, including a switch component, a resistor R1, a capacitor C1, and a microcontroller;
[0006] The microcontroller includes a main controller and an input pin KEY. The input pin KEY is connected to the first end of the resistor R1 and the first end of the capacitor C1. The second end of the capacitor C1 is used to connect to the positive power supply VCC terminal, and the second end of the resistor R1 is used to connect to the power supply ground GND terminal;
[0007] The switch component is used to be installed on the circuit board of the point reading pen. One end of the switch component is used to connect to the positive power supply VCC terminal and the second end of the capacitor C1, and the other end of the switch component is connected to the first end of the capacitor C1 and the first end of the resistor R1;
[0008] The switch component has a closed state and an open state. In the closed state, the capacitor C1 discharges to the power supply ground GND terminal through the resistor R1; in the open state, the capacitor C1 charges to the positive power supply VCC terminal;
[0009] The main controller is used to detect whether the level of the input pin KEY changes, and the main controller is used to connect to the power switch of the point reading pen.
[0010] Optionally, the switch assembly includes a housing, a conductive member, and two conducting members;
[0011] The housing includes a housing body and a sealing plate. The housing body has a receiving cavity. The conductive member is movably disposed in the receiving cavity. An opening communicating with the receiving cavity is formed on the housing body. The sealing plate is located in the receiving cavity and is connected to the inner cavity wall of the receiving cavity;
[0012] The conductive member is configured as a metal ball structure;
[0013] Each of the conducting members includes a metal contact and a connecting portion. The two metal contacts are spaced apart on one side of the sealing plate facing the receiving cavity. Both of the two metal contacts have connecting portions passing through the sealing plate. The connecting portion of one of the two metal contacts is used to connect to the positive power supply VCC terminal and the second terminal of the capacitor C1. The connecting portion of the other of the two metal contacts is connected to the first terminal of the capacitor C1 and the first terminal of the resistor R1;
[0014] In the closed state, the metal ball structure is connected to the two metal contacts; in the open state, the metal ball structure is separated from the two metal contacts simultaneously, or the metal ball structure is separated from one of the two metal contacts.
[0015] Optionally, the diameter of the receiving cavity is greater than the diameter of the metal ball structure, and the length of the receiving cavity is greater than the diameter of the metal ball structure.
[0016] Optionally, an included angle is formed between the extending direction of the housing body and the center line arranged vertically on the circuit board.
[0017] Optionally, the included angle is greater than 40° and less than 50°.
[0018] Through the above technical solution, by setting the resistor R1 and the capacitor C1, an RC charge-discharge loop can be formed. When the switch component is in the off state, the capacitor C1 starts to charge through the positive VCC terminal of the power supply; when the switch component is in the on state, the capacitor C1 discharges through the resistor R1 to the ground GND terminal of the power supply. At this time, the voltage on the capacitor C1 will drop. Since the capacitor C1 is connected to the input pin KEY, the change in the voltage of the capacitor C1 can be detected by the main controller of the microcontroller. The microcontroller determines the state change of the switch component by monitoring the level change of the input pin KEY, thereby triggering corresponding actions, such as starting the power switch of the point reading pen to wake up the point reading pen or closing the power switch of the point reading pen to make the point reading pen enter the sleep state. Specifically, when the level change of the input pin KEY is detected, the automatic wake-up function of the point reading pen can be realized. When the level change of the input pin KEY is not detected, the automatic sleep function of the point reading pen can be realized, that is, the low-power mode. That is to say, the point reading pen is only activated when the user triggers the switch component. Such a design is simple in structure and easy to implement, and only a few basic electronic components are required to complete it. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0023] The following will describe in detail the specific embodiments of the present disclosure with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for explaining and illustrating the present disclosure, and are not used to limit the present disclosure.
[0024] In the description of the present disclosure, in the present disclosure, unless otherwise stated, "inside and outside" refer to the inside and outside of the contour of the corresponding component. In addition, the terms "first", "second", etc. used are to distinguish one element from another, and do not have sequentiality and importance.
[0025] In the description of the present disclosure, it should also be noted that, unless otherwise clearly specified and limited, the terms "set", "connect", "couple", and "install" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.
[0026] As Figures 1 to 3 shown, the present disclosure provides an automatic wake-up system for a point-reading pen, including a switch assembly 10, a resistor R120, a capacitor C130, and a microcontroller. The microcontroller includes a main controller and an input pin KEY40. The input pin KEY40 is connected to the first end of the resistor R120 and the first end of the capacitor C1. The second end of the capacitor C1 is used to connect to the positive power supply VCC terminal, and the second end of the resistor R120 is used to connect to the power supply ground GND terminal. The switch assembly 10 is used to be installed on the circuit board 50 of the point-reading pen. One end of the switch assembly 10 is used to connect to the positive power supply VCC terminal and the second end of the capacitor C1, and the other end of the switch assembly 10 is connected to the first end of the capacitor C1 and the first end of the resistor R120. The switch assembly 10 has a closed state and an open state. In the closed state, the capacitor C1 discharges to the power supply ground GND terminal through the resistor R120; in the open state, the capacitor C1 charges to the positive power supply VCC terminal. The main controller is used to detect whether the level of the input pin KEY40 changes, and the main controller is used to connect to the power switch of the point-reading pen.
[0027] Among them, the resistor R120 is used to limit the charging current and discharging current of the capacitor C1, and its resistance value is 10 kΩ.
[0028] Among them, the capacitor C1 is used to store charges and generate a level change through charging and discharging, and its capacitance is 0.1 nF.
[0029] Among them, the input pin KEY40 is connected to the resistor R120 and the capacitor C1, and is used to detect the voltage change on the capacitor C1.
[0030] The microcontroller includes a main controller and an input pin KEY40. The main controller can detect whether the level of the input pin KEY40 changes, and form a wake-up signal according to the level change to perform corresponding operations.
[0031] Among them, through the above technical solution, the resistor R120 and the capacitor C1 can form an RC charge-discharge loop. When the switch component 10 is in the off state, the capacitor C1 starts to charge through the positive VCC terminal of the power supply; when the switch component 10 is in the on state, the capacitor C1 discharges to the ground GND terminal of the power supply through the resistor R120. At this time, the voltage on the capacitor C1 will drop. Since the capacitor C1 is connected to the input pin KEY40, the change in the voltage of the capacitor C1 can be detected by the main controller of the microcontroller. The microcontroller judges the state change of the switch component 10 by monitoring the level change of the input pin KEY40, thereby triggering corresponding actions, such as starting the power switch of the point-reading pen to wake up the point-reading pen or turning off the power switch of the point-reading pen to make the point-reading pen enter the sleep state. Specifically, when the level change of the input pin KEY40 is detected, the automatic wake-up function of the point-reading pen can be realized. When the level change of the input pin KEY40 is not detected, the automatic sleep function of the point-reading pen can be realized, that is, the low-power mode. That is to say, the point-reading pen will only be activated when the user triggers the switch component 10. With such a design, the structure is simple and easy to implement, and only a few basic electronic components are required to complete it.
[0032] In addition, after power-on, during the user's use of the point-reading pen, each point-reading will hit the book page with the pen tip. In this way, the detection of the state of the switch component 10 can also be triggered. The microcontroller can record the timestamp, duration, and frequency of each point-reading by the user. These data can be used to analyze the user's point-reading habits, such as the time period of point-reading every day, the frequency of point-reading, etc. In this way, through statistical and learning algorithms, the system can identify the user's preferences and learning styles. Based on this information, the point-reading pen system can generate personalized learning suggestions and plans to help users learn more efficiently.
[0033] As an implementation method, such as Figure 2As shown in the figure, the switch assembly 10 includes a housing 11, a conductive member, and two conductive members 13. The housing 11 includes a housing main body 111 and a sealing plate 112. The housing main body 111 has a receiving cavity 113. The conductive member is movably disposed in the receiving cavity 113. An opening communicating with the receiving cavity 113 is formed in the housing main body 111. The sealing plate 112 is located in the receiving cavity 113 and is connected to the inner cavity wall of the receiving cavity 113. The conductive member is configured as a metal ball structure 12. Each conductive member 13 includes a metal contact 131 and a connecting portion 132. The two metal contacts 131 are spaced apart on one side of the sealing plate 112 facing the receiving cavity 113. Both of the two metal contacts 131 have a connecting portion 132 passing through the sealing plate 112. The connecting portion 132 of one of the two metal contacts 131 is used to connect to the positive VCC terminal of the power supply and the second terminal of the capacitor C1. The connecting portion 132 of the other of the two metal contacts 131 is connected to the first terminal of the capacitor C1 and the first terminal of the resistor R120. In the closed state, the metal ball structure 12 is connected to the two metal contacts 131; in the open state, the metal ball structure 12 is separated from the two metal contacts 131 simultaneously, or the metal ball structure 12 is separated from one of the two metal contacts 131.
[0034] When the user picks up the point reading pen, it can make the point reading pen in a shaking state. At the same time, under the action of gravity, the metal ball structure 12 will also move in the housing main body 111. In this way, when the metal ball structure 12 moves and contacts the two metal contacts 131, a closed circuit can be formed. At this time, the switch assembly 10 is in the closed state, and C1 starts to discharge. When the metal ball structure 12 moves and contacts one metal contact 131 or is separated from the two metal contacts 131, the switch assembly 10 is in the open state, and the capacitor C1 starts to charge. The charging and discharging process of the capacitor C1 will cause the voltage across the capacitor C1 to change, so that the level of the input pin KEY40 connected to the capacitor C1 can change. Moreover, the microcontroller can judge whether to wake up the point reading pen by detecting the level change of the input pin KEY40. In other words, as long as the user moves the point reading pen, the microcontroller can detect that the level of the input pin KEY40 changes, and it can be judged that the user needs to use point reading, generating a wake-up signal. The main controller starts the power switch of the point reading pen according to the wake-up signal, thus realizing the automatic wake-up function of the point reading pen. Such a setting can use a simple mechanical structure (the metal ball and the two metal contacts 131) to control the on-off of the circuit, thus realizing the automatic wake-up function of the point reading pen. This design is not only simple and reliable, but also can effectively reduce the power consumption of the point reading pen and improve the user experience.
[0035] In order to ensure that the metal ball structure 12 can move freely in the receiving cavity 113, so as to realize the vibration switch function of the switch assembly 10, optionally, as Figure 2As shown, the diameter of the accommodation cavity 113 is greater than the diameter of the metal ball structure 12, and the length of the accommodation cavity 113 is greater than the diameter of the metal ball structure 12.
[0036] As an implementation manner, as Figure 3 shown, there is an included angle between the extending direction of the shell main body 111 and the center line arranged vertically on the circuit board 50.
[0037] Since there are three situations for the connection between the metal ball structure 12 and the two metal contacts 131. The first situation is that the metal ball structure 12 does not contact either of the two metal contacts 131. The second situation is that the metal ball structure 12 only contacts one of the two metal contacts 131. The third situation is that the metal ball structure 12 contacts both of the two metal contacts 131. Among them, in the first situation, the switch assembly 10 is in the closed state. In the second or third situation, the switch assembly 10 is in the open state. Therefore, when the initial state of the switch assembly 10 is the second situation (the metal ball structure 12 only contacts one of the two metal contacts 131), it can be quickly switched to the first situation or the third situation. That is to say, by arranging the switch assembly 10 obliquely on the circuit board 50, the metal ball structure 12 can be made to only contact one of the two metal contacts 131. In this way, when the user picks up the point-reading pen and causes shaking or vibration, the metal ball structure 12 can quickly contact the other metal contact 131 or separate from the currently contacted metal contact 131, so that the switch assembly 10 can quickly switch between the closed state and the open state, thereby improving the sensitivity and response speed of the switch assembly 10 and making the automatic wake-up function of the point-reading pen more rapid and reliable.
[0038] In order to achieve the purpose that the metal ball structure 12 only contacts one of the two metal contacts 131, optionally, as Figure 3 shown, the included angle is greater than 40° and less than 50°.
[0039] Among them, the preferred installation angle adopted in the present disclosure is 45°.
[0040] The preferred embodiments of the present disclosure have been described in detail above with reference to the accompanying drawings. However, the present disclosure is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all belong to the protection scope of the present disclosure.
[0041] In addition, it should be noted that, in the above specific embodiments, the various specific technical features described can be combined in any suitable manner without conflict. To avoid unnecessary repetition, the present disclosure will not separately describe various possible combination manners.
[0042] In addition, any combination can be made among various different embodiments of the present disclosure, as long as it does not violate the idea of the present disclosure, and it should equally be regarded as the content disclosed by the present disclosure.
