Technical Field

[0001] This utility model relates to the field of writing interaction device technology, and in particular to a writing interaction device and writing interaction component. Background Technology

[0002] In existing writing instruction and cultural tourism interactive projects, especially in scenarios targeting children, current systems mostly use LCD screens as the core interactive medium. Users need to continuously look at the screen to display verification results. However, this type of interaction method relying on LCD screens has significant drawbacks: the blue light radiation and brightness fluctuations generated during screen operation, as well as the visual focus required by users to follow the screen content, can easily lead to visual fatigue. This is especially true for children in the critical period of visual development; such interaction modes are more likely to exacerbate eye strain, increase the risk of myopia, and are detrimental to vision protection. Utility Model Content To address the aforementioned problems, this utility model provides a writing interaction device and a writing interaction component.

[0003] The present invention provides a writing interaction device, comprising a verification control module and an interaction module, which are electrically connected. The interaction module includes a font component, a receiving component, a base, and an electric support rod. The receiving component has a receiving space in which the font component is housed. The electric support rod is telescopically connected to the font component and the base. The verification control module can control the electric support rod to move the font component from the receiving space towards the base.

[0004] Preferably, the interaction module further includes multiple switch-type sensors, defining the side of the font component away from the base as the font surface, the multiple switch-type sensors are disposed at preset positions on the font surface, the multiple switch-type sensors are electrically connected to the verification control module, and when the multiple switch-type sensors are triggered in a preset sequence, the verification control module sends a first signal to control the retraction of the electric strut.

[0005] Preferably, the font element includes at least one stroke portion, and a plurality of the switch-type sensors on the stroke portion are sequentially spaced along the trajectory of the corresponding stroke.

[0006] Preferably, the spacing between the plurality of switch-type sensors arranged horizontally on the stroke portion is different from the spacing between the plurality of switch-type sensors arranged vertically on the stroke portion; or, the spacing between the plurality of switch-type sensors on the stroke portion is the same.

[0007] Preferably, the electric strut includes an outer rod, an inner rod, and a drive assembly. The outer rod is disposed on the base and has a sliding hole. The inner rod is at least partially disposed in the sliding hole and is slidably connected to the outer rod. The drive assembly is drively connected to the inner rod. When the verification control module sends the first signal, the drive assembly drives the inner rod to move toward the base.

[0008] Preferably, the verification control module includes an MCU (Microcontroller Unit).

[0009] Preferably, the switch-type sensor is a Hall switch.

[0010] Preferably, the font component includes at least one stroke portion, and the interaction module further includes an indicator light corresponding to the stroke portion. When multiple switch-type sensors on the stroke portion are triggered in a preset order, the verification control module controls the indicator light corresponding to the stroke portion to light up.

[0011] Preferably, the interaction module further includes at least one set of speakers; When the verification control module sends a first signal, the verification control module controls the speaker to emit a preset first prompt tone; and / or, the font element includes at least one stroke portion, and when multiple switch-type sensors on the stroke portion are triggered in a preset order, the verification control module controls the speaker corresponding to the stroke portion to emit a preset second prompt tone.

[0012] To solve the above-mentioned technical problems, this utility model provides another technical solution as follows: a writing interaction component, the writing interaction component including a terminal device and the writing interaction device described above, the writing interaction device being provided with an output interface, the output interface being electrically connected to the terminal device.

[0013] Compared with the prior art, the writing interaction device and writing interaction component provided by this utility model have the following beneficial effects: 1. This utility model provides a writing interaction device, which includes a verification control module and an interaction module. The verification control module and the interaction module are electrically connected. The interaction module includes a font component, a receiving component, a base, and an electric support rod. The receiving component has a receiving space, in which the font component is stored. The electric support rod is telescopically connected to the font component and the base. The verification control module can control the electric support rod to move the font component towards the base. Through the above settings, the font component can automatically switch between a stored state and a used state. When the electric support rod moves the font component towards the base, the font component sinks from the receiving space, forming a concave engraving effect, which can achieve the effect of correctly displaying the writing stroke verification result. It can display the writing verification result to the user without relying on an LCD screen, avoiding visual fatigue caused by prolonged screen viewing. It deepens the memory of stroke order while avoiding visual fatigue caused by prolonged screen viewing, which is especially suitable for sensitive groups such as children. At the same time, the mechanical structure interaction method can provide physical feedback, enhancing the user's immersion and realism when using the writing interaction device.

[0014] 2. The interactive module provided in this embodiment of the utility model also includes multiple switch-type sensors. The side of the font component away from the base is defined as the font surface. The multiple switch-type sensors are set at preset positions on the font surface and are electrically connected to the verification control module. When the multiple switch-type sensors are triggered in a preset order, the verification control module sends a first signal to control the retraction of the electric support rod. By setting multiple switch-type sensors at preset positions on the font surface and electrically connecting them to the verification control module, the verification control module only sends the first signal to control the retraction of the electric support rod when the multiple switch-type sensors are triggered in a preset order. This ensures the accuracy and reliability of the writing stroke order verification and avoids the complex algorithm errors of traditional image recognition. After the first signal to control the retraction of the electric support rod is issued, the electric support rod retracts so that the font component moves from the receiving space towards the base, realizing instant interaction. At the same time, the triggering method of the switch-type sensors responds quickly and can provide real-time feedback on whether the stroke writing order is correct.

[0015] 3. The font component provided in this embodiment includes at least one stroke portion, and multiple switch-type sensors on the stroke portion are sequentially and spaced apart along the trajectory of the corresponding stroke. By dividing the font component into at least one stroke portion and sequentially and spaced apart along the trajectory of the corresponding stroke, the stroke trajectory is represented only by the arrangement of multiple switch-type sensors. The switch-type sensors can exist only at key nodes of the stroke, rather than continuously covering the entire stroke trajectory, reducing the number of switch-type sensors used, thereby reducing manufacturing costs while ensuring the accuracy of stroke order verification.

[0016] 4. In this embodiment of the invention, the spacing between the multiple switch-type sensors arranged horizontally on the stroke portion is different from the spacing between the multiple switch-type sensors arranged vertically on the stroke portion; or, the spacing between the multiple switch-type sensors on the stroke portion is the same. By setting the spacing between the multiple switch-type sensors arranged horizontally and vertically on the stroke portion to be different or the same, the adaptability and flexibility of the writing interaction device are enhanced. When the spacing between the multiple switch-type sensors arranged horizontally and vertically on the stroke portion is different, the spacing between the multiple switch-type sensors in the horizontal and vertical directions can be adjusted according to the writing rhythm of different strokes and the compactness between strokes. A larger spacing is suitable for strokes that are longer in the horizontal or vertical direction and have a slower writing rhythm, thereby reducing redundant triggering. A smaller spacing is suitable for strokes that are relatively compact in the horizontal or vertical direction and have a faster writing speed, thereby improving detection sensitivity. When the spacing between the multiple switch-type sensors arranged horizontally and vertically on the stroke portion is the same, it is beneficial to standardize production to reduce processing costs. Different schemes can be flexibly adjusted according to specific scenarios such as font type, expanding the applicability of the writing interaction device.

[0017] 5. The electric support rod provided in this embodiment of the utility model includes an outer rod, an inner rod, and a drive assembly. The outer rod is mounted on a base and has a sliding hole. The inner rod is at least partially disposed within the sliding hole, and the inner rod is slidably connected to the outer rod. The drive assembly is drively connected to the inner rod. When the verification control module sends a first signal, the drive assembly drives the inner rod to move towards the base. Through the sliding connection structure of the outer and inner rods and the transmission design of the drive assembly, the extension and retraction movement of the electric support rod is made more stable and reliable. The outer rod provides guiding support, and the inner rod slides smoothly within the sliding hole, avoiding deviation or jamming during the movement of the font. The drive assembly drives the inner rod, ensuring efficient power transmission and guaranteeing that the font can move accurately and smoothly from the stored state to the usage position, thus improving the stability of the writing interaction device's movement.

[0018] 6. The verification control module provided in this embodiment of the present invention includes an MCU (Micro Controller Unit). The verification control module uses an MCU, fully utilizing its low cost, low power consumption, and high integration. The MCU can efficiently process sensor signals and control the movement of the electric strut, etc., meeting the logical operation requirements of stroke order verification without the need for a high-performance processor. This significantly reduces the hardware cost and energy consumption of the writing interaction device, making it suitable for mass production and portable applications. Furthermore, its miniaturization facilitates integration into the writing interaction device, effectively saving space.

[0019] 7. The switch-type sensor provided in this embodiment is a Hall switch. Choosing a Hall switch as the switch-type sensor leverages its advantages of no mechanical contact, fast response speed, and strong anti-interference capability. Triggered by changes in magnetic field, it avoids the wear and tear of mechanical contacts, extending its service life, making it particularly suitable for scenarios where children frequently trigger the sensor through writing. Simultaneously, its resistance to external interference ensures triggering stability in complex usage environments.

[0020] 8. The font component provided in this embodiment includes at least one stroke portion, and the interaction module also includes indicator lights corresponding to the stroke portion. When multiple switch-type sensors on the stroke portion are triggered in a preset order, the verification control module controls the indicator lights corresponding to the stroke portion to illuminate. By setting indicator lights corresponding to the stroke portions, intuitive visual feedback is provided to the user. When the switch-type sensors on the stroke portion are triggered in a preset order, the corresponding indicator lights illuminate, allowing the user to know in real time whether the current stroke is written correctly. Feedback information can be obtained without relying on the screen, which protects eyesight and strengthens the memory of the correct stroke order through light guidance. It is especially easier for young children to understand and accept, making the interaction more effective.

[0021] 9. The interactive module provided in this embodiment of the utility model further includes at least one set of speakers; when the verification control module sends a first signal, the verification control module controls the speakers to emit a preset first prompt tone; and / or, the font element includes at least one stroke portion, and when multiple switch-type sensors on the stroke portion are triggered in a preset order, the verification control module controls the speaker corresponding to the stroke portion to emit a preset second prompt tone. By setting the speakers, when the verification control module sends a first signal, the verification control module controls the speakers to emit a preset first prompt tone to inform the user that all stroke orders corresponding to the Chinese character are completely correct, providing feedback on the operation result. When multiple switch-type sensors on the stroke portion are triggered in a preset order, the verification control module controls the speaker corresponding to the stroke portion to emit a preset second prompt tone to indicate that the stroke order corresponding to the second prompt tone is written correctly, strengthening the positive incentive for correct operation, combining sound feedback with mechanical and visual feedback, enriching the interactive experience, and improving the feedback effect of the interaction.

[0022] 10. The writing interaction component provided in this embodiment of the present utility model includes a terminal device and the writing interaction device described above. The writing interaction device is provided with an output interface, which is electrically connected to the terminal device. The writing interaction component can achieve the same beneficial effects as the writing interaction device, which will not be described in detail here. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0031] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

These terms are primarily for the purpose of better describing this invention and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0033] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this utility model according to the specific circumstances.

[0034] Furthermore, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this utility model based on the specific circumstances.

[0035] Please combine Figures 1 to 3 The first embodiment of this utility model provides a writing interaction device 1, which includes a verification control module 20 and an interaction module 10. The verification control module 20 and the interaction module 10 are electrically connected. The interaction module 10 includes a font component 11, a receiving component 12, a base 13, and an electric support rod 14. The receiving component 12 has a receiving space 121, in which the font component 11 is housed. The electric support rod 14 can extend and retract to connect the font component 11 and the base 13. The verification control module can control the electric support rod 14 to drive the font component 11 to move from the receiving space 121 toward the base 13.

[0036] Understandably, the above setup enables automatic switching between the font component 11's stored and used states. When the electric support rod 14 moves the font component 11 towards the base 13, and the font component 11 sinks from the receiving space 121 to form a recessed engraving effect, it can effectively display the written stroke verification results, i.e., from... Figure 2 The font component 11 shown is stored in the storage space 121. The font component 11 is then moved closer to the base 13 in a retracted state. The writing verification results can be displayed to the user without relying on the LCD screen, avoiding visual fatigue caused by prolonged screen viewing. This deepens the memory of stroke order while avoiding visual fatigue caused by prolonged screen viewing, making it especially suitable for sensitive groups such as children. At the same time, the mechanical structure interaction method can provide physical feedback, enhancing the user's immersion and sense of realism when using the writing interaction device 1.

[0037] Please combine Figure 1 and Figure 2 Furthermore, the interaction module 10 also includes multiple switch-type sensors 15, defining the side of the font element 11 away from the base 13 as the font surface 111. The multiple switch-type sensors 15 are set at preset positions on the font surface 111. The multiple switch-type sensors 15 are electrically connected to the verification control module 20. When the multiple switch-type sensors 15 are triggered in a preset order, the verification control module 20 sends a first signal to control the retraction of the electric support rod 14.

[0038] Understandably, by setting multiple switch-type sensors 15 at preset positions on the font surface 111, and electrically connecting these sensors 15 to the verification control module 20, the verification control module 20 only sends a first signal to control the retraction of the electric support rod 14 when the multiple switch-type sensors 15 are triggered in a preset order. This ensures the accuracy and reliability of the writing stroke order verification and avoids the complex algorithm errors of traditional image recognition. After the first signal to control the retraction of the electric support rod 14 is issued, the electric support rod 14 retracts so that the font component 11 moves from the receiving space 121 towards the base 13, achieving instant interaction. At the same time, the triggering method of the switch-type sensors 15 responds quickly and can provide real-time feedback on whether the stroke writing order is correct.

[0039] Please combine Figure 1 and Figure 4 Furthermore, the font component 11 includes at least one stroke portion 112, and a plurality of switch-type sensors 15 on the stroke portion 112 are sequentially and spaced apart along the trajectory of the corresponding stroke.

[0040] Understandably, by dividing the font member 11 into at least one stroke portion 112, and arranging the switch-type sensors 15 sequentially at intervals along the trajectory of the corresponding stroke, the stroke trajectory is represented only by the arrangement of the plurality of switch-type sensors 15. The switch-type sensors 15 can only be present at the key nodes of the stroke, instead of being required to continuously cover the entire stroke trajectory, which reduces the number of switch-type sensors 15 used, thereby lowering the manufacturing cost while ensuring the accuracy of stroke order verification.

[0041] Optionally, taking the Chinese character "Zhong" on the font member 11 as an example, the stroke portions 112 of the font member 11 include a first stroke portion 1121 "Yi (horizontal stroke)", a second stroke portion 1122 " ", a third stroke portion 1123 "Yi (horizontal stroke)", and a fourth stroke portion 1124 "Shu (vertical stroke)". The plurality of switch-type sensors 15 on the first stroke portion 1121, the second stroke portion 1122, the third stroke portion 1123 and the fourth stroke portion are all sequentially arranged at intervals along the trajectory of the corresponding stroke.

[0042] Please refer to Figure 4 , further, the spacing between the plurality of switch-type sensors 15 arranged horizontally on the stroke portion 112 is different from the spacing between the plurality of switch-type sensors 15 arranged vertically on the stroke portion 112; or, the spacing between the plurality of switch-type sensors 15 on the stroke portion 112 is the same.

[0043] Understandably, by setting the spacing between the plurality of switch-type sensors 15 arranged horizontally and vertically on the stroke portion 112 to be different or the same, the adaptability and flexibility of the writing interaction device 1 are enhanced. When the spacing between the plurality of switch-type sensors 15 arranged horizontally and the plurality of switch-type sensors 15 arranged vertically on the stroke portion 112 is different, the spacing of the plurality of switch-type sensors 15 in the horizontal and vertical directions can be adjusted according to the writing rhythm of different strokes and the compactness between strokes. A larger spacing is suitable for strokes that extend longer in the horizontal or vertical direction and have a gentle writing rhythm, thereby reducing redundant triggers. A smaller spacing is suitable for strokes that are relatively compact in the horizontal or vertical direction and have a fast writing speed, which can improve detection sensitivity. When the spacing between the plurality of switch-type sensors 15 arranged horizontally and the plurality of switch-type sensors 15 arranged vertically on the stroke portion 112 is the same, it is conducive to standardized production to reduce processing costs. Different solutions can be flexibly adjusted according to specific scenarios such as font types, which expands the applicable scope of the writing interaction device 1.

[0044] Please combine Figures 1 to 3Furthermore, the electric strut 14 includes an outer rod 141, an inner rod 142, and a drive assembly 143. The outer rod 141 is mounted on the base 13 and has a sliding hole 1411. The inner rod 142 is at least partially disposed within the sliding hole 1411 and is slidably connected to the outer rod 141. The drive assembly 143 is drively connected to the inner rod 142. When the verification control module 20 sends a first signal, the drive assembly 143 drives the inner rod 142 to move toward the base 13.

[0045] Understandably, the sliding connection structure of the outer rod 141 and the inner rod 142, along with the transmission design of the drive assembly 143, makes the telescopic movement of the electric support rod 14 more stable and reliable. The outer rod 141 provides guiding support, and the inner rod 142 slides smoothly within the sliding hole 1411, preventing the font component 11 from shifting or jamming during movement. The drive assembly 143 drives the inner rod 142, ensuring efficient power transmission and guaranteeing that the font component 11 can move accurately and smoothly from the stored state to the usage position, thereby improving the stability of the writing interaction device 1's movement.

[0046] Please see Figure 1 Furthermore, the verification control module 20 includes an MCU microcontroller unit.

[0047] Understandably, the verification control module 20 adopts an MCU (Micro Controller Unit), which fully utilizes its low cost, low power consumption and high integration. The MCU can efficiently process sensor signals and control the movement of the electric support rod 14. It can meet the logical operation requirements of stroke order verification without the need for a high-performance processor, which greatly reduces the hardware cost and energy consumption of the writing interaction device 1. It is suitable for mass production and portable applications. At the same time, its miniaturization makes it easy to integrate into the writing interaction device 1, which can effectively save space.

[0048] Please continue reading. Figure 1 Furthermore, the switch-type sensor 15 is a Hall switch.

[0049] Understandably, a Hall effect switch was chosen as the switching sensor 15, leveraging its advantages of no mechanical contact, fast response speed, and strong anti-interference capability. Triggered by changes in magnetic field, it avoids the wear and tear of mechanical contacts, extending its service life, making it particularly suitable for scenarios where children frequently trigger the sensor through writing. Simultaneously, its resistance to external interference ensures triggering stability in complex usage environments.

[0050] Please combine Figure 1 and Figure 4Furthermore, the font component 11 includes at least one stroke portion 112, and the interaction module 10 also includes an indicator light 16 corresponding to the stroke portion 112. When multiple switch-type sensors 15 on the stroke portion 112 are triggered in a preset order, the verification control module 20 controls the indicator light 16 corresponding to the stroke portion 112 to light up.

[0051] Understandably, by setting up indicator lights 16 corresponding to the stroke section 112, intuitive visual feedback is provided to the user. When the switch-type sensor 15 of the stroke section 112 is triggered in a preset sequence, the corresponding indicator light 16 lights up, allowing the user to know in real time whether the current stroke is written correctly. Feedback information can be obtained without relying on the screen, which not only protects eyesight but also strengthens the memory of the correct stroke order through light guidance. This is especially easy for young children to understand and accept, making the interaction more effective.

[0052] Optionally, the verification control module 20 can control the indicator lights 16 corresponding to the stroke section 112 to illuminate. Different stroke sections 112 may correspond to different indicator lights 16. When multiple switch-type sensors 15 on a certain stroke section 112 are triggered in a preset sequence, the indicator light 16 corresponding to that stroke section 112 will illuminate. Alternatively, different stroke sections 112 may correspond to the same indicator light 16. When multiple switch-type sensors 15 on a certain stroke section 112 are triggered in a preset sequence, the indicator light 16 will emit light of the color corresponding to that stroke section 112.

[0053] Please combine Figure 1 and Figure 4 Furthermore, the interaction module 10 also includes at least one set of speakers 17; when the verification control module 20 sends a first signal, the verification control module 20 controls the speakers 17 to emit a preset first prompt tone; and / or, the font element 11 includes at least one stroke portion 112, and when multiple switch-type sensors 15 on the stroke portion 112 are triggered in a preset order, the verification control module 20 controls the speakers 17 corresponding to the stroke portion 112 to emit a preset second prompt tone.

[0054] Understandably, by setting up speaker 17, when the verification control module 20 sends a first signal, the verification control module 20 controls speaker 17 to emit a preset first prompt tone, which is used to inform the user that all strokes of the Chinese character are completely correct, providing feedback on the operation result. When multiple switch-type sensors 15 on the stroke section 112 are triggered in a preset order, the verification control module 20 controls speaker 17 corresponding to the stroke section 112 to emit a preset second prompt tone, which is used to indicate that the stroke order corresponding to the second prompt tone is written correctly, strengthening the positive incentive for correct operation, and combining sound feedback with mechanical and visual feedback, enriching the interactive experience and improving the feedback effect of the interaction.

[0055] Please see Figure 5The second embodiment of this utility model provides a writing interaction component 100, which includes a terminal device 2 and a writing interaction device 1 of the first embodiment of this utility model. The writing interaction device 1 is provided with an output interface 101, which is electrically connected to the terminal device 2.

[0056] Understandably, the writing interaction component 100 can achieve the same beneficial effects as the writing interaction device 1, which will not be elaborated here.

[0057] Compared with the prior art, the writing interaction device and writing interaction component of this utility model have the following advantages: 1. This utility model provides a writing interaction device, which includes a verification control module and an interaction module.

[0058] 2. The interactive module provided in this embodiment of the utility model also includes multiple switch-type sensors. The side of the font component away from the base is defined as the font surface. The multiple switch-type sensors are set at preset positions on the font surface and are electrically connected to the verification control module.

At the same time, the triggering method of the switch-type sensors responds quickly and can provide real-time feedback on whether the stroke writing order is correct.

[0059] 3. The font component provided in this embodiment includes at least one stroke portion, and multiple switch-type sensors on the stroke portion are sequentially and spaced apart along the trajectory of the corresponding stroke. By dividing the font component into at least one stroke portion and sequentially and spaced apart along the trajectory of the corresponding stroke, the stroke trajectory is represented only by the arrangement of multiple switch-type sensors. The switch-type sensors can exist only at key nodes of the stroke, rather than continuously covering the entire stroke trajectory, reducing the number of switch-type sensors used, thereby reducing manufacturing costs while ensuring the accuracy of stroke order verification.

[0060] 4. In this embodiment of the invention, the spacing between the multiple switch-type sensors arranged horizontally on the stroke portion is different from the spacing between the multiple switch-type sensors arranged vertically on the stroke portion; or, the spacing between the multiple switch-type sensors on the stroke portion is the same. By setting the spacing between the multiple switch-type sensors arranged horizontally and vertically on the stroke portion to be different or the same, the adaptability and flexibility of the writing interaction device are enhanced.

When the spacing between the multiple switch-type sensors arranged horizontally and vertically on the stroke portion is the same, it is beneficial to standardize production to reduce processing costs. Different schemes can be flexibly adjusted according to specific scenarios such as font type, expanding the applicability of the writing interaction device.

[0061] 5. The electric support rod provided in this embodiment of the utility model includes an outer rod, an inner rod, and a drive assembly. The outer rod is mounted on a base and has a sliding hole. The inner rod is at least partially disposed within the sliding hole, and the inner rod is slidably connected to the outer rod. The drive assembly is drively connected to the inner rod. When the verification control module sends a first signal, the drive assembly drives the inner rod to move towards the base. Through the sliding connection structure of the outer and inner rods and the transmission design of the drive assembly, the extension and retraction movement of the electric support rod is made more stable and reliable. The outer rod provides guiding support, and the inner rod slides smoothly within the sliding hole, avoiding deviation or jamming during the movement of the font. The drive assembly drives the inner rod, ensuring efficient power transmission and guaranteeing that the font can move accurately and smoothly from the stored state to the usage position, thus improving the stability of the writing interaction device's movement.

[0062] 6. The verification control module provided in this embodiment of the present invention includes an MCU (Micro Controller Unit). The verification control module uses an MCU, fully utilizing its low cost, low power consumption, and high integration. The MCU can efficiently process sensor signals and control the movement of the electric strut, etc., meeting the logical operation requirements of stroke order verification without the need for a high-performance processor. This significantly reduces the hardware cost and energy consumption of the writing interaction device, making it suitable for mass production and portable applications. Furthermore, its miniaturization facilitates integration into the writing interaction device, effectively saving space.

[0063] 7. The switch-type sensor provided in this embodiment is a Hall switch. Choosing a Hall switch as the switch-type sensor leverages its advantages of no mechanical contact, fast response speed, and strong anti-interference capability. Triggered by changes in magnetic field, it avoids the wear and tear of mechanical contacts, extending its service life, making it particularly suitable for scenarios where children frequently trigger the sensor through writing. Simultaneously, its resistance to external interference ensures triggering stability in complex usage environments.

[0064] 8. The font component provided in this embodiment includes at least one stroke portion, and the interaction module also includes indicator lights corresponding to the stroke portion. When multiple switch-type sensors on the stroke portion are triggered in a preset order, the verification control module controls the indicator lights corresponding to the stroke portion to illuminate. By setting indicator lights corresponding to the stroke portions, intuitive visual feedback is provided to the user. When the switch-type sensors on the stroke portion are triggered in a preset order, the corresponding indicator lights illuminate, allowing the user to know in real time whether the current stroke is written correctly. Feedback information can be obtained without relying on the screen, which protects eyesight and strengthens the memory of the correct stroke order through light guidance. It is especially easier for young children to understand and accept, making the interaction more effective.

[0065] 9. The interactive module provided in this embodiment of the utility model further includes at least one set of speakers; when the verification control module sends a first signal, the verification control module controls the speakers to emit a preset first prompt tone; and / or, the font element includes at least one stroke portion, and when multiple switch-type sensors on the stroke portion are triggered in a preset order, the verification control module controls the speaker corresponding to the stroke portion to emit a preset second prompt tone. By setting the speakers, when the verification control module sends a first signal, the verification control module controls the speakers to emit a preset first prompt tone to inform the user that all stroke orders corresponding to the Chinese character are completely correct, providing feedback on the operation result. When multiple switch-type sensors on the stroke portion are triggered in a preset order, the verification control module controls the speaker corresponding to the stroke portion to emit a preset second prompt tone to indicate that the stroke order corresponding to the second prompt tone is written correctly, strengthening the positive incentive for correct operation, combining sound feedback with mechanical and visual feedback, enriching the interactive experience, and improving the feedback effect of the interaction.

[0066] 10. The writing interaction component provided in this embodiment of the present utility model includes a terminal device and the writing interaction device described above. The writing interaction device is provided with an output interface, which is electrically connected to the terminal device. The writing interaction component can achieve the same beneficial effects as the writing interaction device, which will not be described in detail here.

[0067] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the principles of the present utility model should be included within the protection scope of the present utility model.
