[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figures 1 to 4 As shown, this utility model provides a child companion device that simulates dynamic facial expressions, including a lower shell 1, a memory metal spring 2, several sticky notes 3, and a storage box 4. An upper body 11 is fixedly provided on the top of the lower shell 1. A display screen 12 is provided on the inner side of the upper body 11. A camera 13 and an infrared emitter 14 are provided on the outer side of the display screen 12. The memory metal spring 2 is tautly set on the outer side of the lower shell 1 and is tightly attached to the outer surface of the lower shell 1 under the action of external force. Several sticky notes 3 are detachably set on the outer side of the memory metal spring 2. The storage box 4 is detachably set on the inner side of the lower shell 1. Magnetic rings A23 are symmetrically arranged on the outer side of the lower shell 1, and the magnetic rings A23 are magnetically attracted to the memory metal spring 2.

[0017] The lower housing 1 serves as the main support structure of the device, bearing the weight of all components and providing installation and positioning functions. The upper housing 11, with its integrated design, provides a sealed and stable installation environment for the display screen 12, camera 13, and infrared emitter 14, preventing damage to delicate components from external dust and collisions. The camera 13 captures the child's facial features in real time, such as the curvature of the corners of the mouth and the degree of eye opening and closing. The infrared emitter 14 emits infrared rays and receives reflected signals, calculating the distance between the device and the child. When the distance is too close, the processor triggers a prompt signal, and guidance content is displayed on the display screen 12. The memory metal spring 2 is initially taut and fixed to the outside of the lower housing 1, allowing the child to attach and detach the sticky note 3, on which the instructions are written. The device facilitates daily learning schedules for children, providing easy reminders of their tasks. When external force is applied to the memory metal spring 2, it deforms and adheres tightly to the surface of the lower housing 1, where it is secured by the external force. When the external force is removed, the memory metal spring 2 returns to its taut state due to the properties of memory metal. Meanwhile, the storage box 4 is installed inside the lower housing 1 to store small items such as sticky notes and pens. The memory metal spring 2 combines deformation adaptability with return stability, providing a flexible mounting medium for the sticky note board 3. The detachable design of the sticky note board allows children to easily change the content, enhancing the device's interactivity and fun. The storage box 4 enables centralized storage of small items, preventing loss and cultivating children's tidying habits. This extends the device's function from emotional companionship to guiding life habits.

[0018] like Figure 2 and Figure 3As shown, a fixing block 21 is fixedly provided on the outside of the memory metal spring 2. The fixing block 21 is fixedly provided on the outside of the lower housing 1. An arc-shaped groove 22 is provided on the outside of the memory metal spring 2. The distance between the position of the magnetic ring A23 on the lower housing 1 and the fixing block 21 is less than the length of the memory metal spring 2.

[0019] The memory metal spring 2 is mechanically fixed to the outer side of the lower housing 1 by the fixing block 21 fixed on the outside, ensuring that the spring will not be displaced as a whole when it is deformed by force. The arc-shaped groove 22 on the outer side of the spring provides it with a straight state. At the same time, when the memory metal spring 2 is bent and pressed against the outer surface of the lower housing 1 by external force, the magnetic ring A23 forms a magnetic attraction with the memory metal spring 2, so that the memory metal spring 2 is tightly attached to the surface of the lower housing 1, ensuring the stability of the memory metal spring 2 when it is stored.

[0020] like Figure 3 As shown, a magnetic ring B31 is provided on the outer side of the sticky note plate 3. The magnetic ring B31 is attached to the inner side of the arc-shaped groove 22. The magnetic ring B31 is magnetically attracted to the memory metal spring 2. A white film is provided on the outer surface of the sticky note plate 3 at the end away from the magnetic ring B31.

[0021] The magnetic ring B31 on the outer side of the sticky note board 3 fits into the arc-shaped groove 22 of the memory metal spring 2. The sticky note board is fixed by the magnetic attraction between the magnetic ring B and the memory metal spring. Since the magnetic attraction has the characteristic of being removable, children can easily remove the sticky note board to draw or write. After finishing, it can be re-attached and fixed to the spring. At the same time, the whiteboard film design at the end of the sticky note board 3 away from the magnetic ring B31 makes the sticky note board reusable. Children can use whiteboard markers to write or draw on the surface. After wiping, it can be reused without frequently replacing sticky notes.

[0022] like Figure 4 As shown, a slider 41 is fixedly provided at the bottom of the storage box 4. The slider 41 is slidably disposed inside the limiting groove 15. The limiting groove 15 is opened at the bottom inside the lower shell 1. Both the limiting groove 15 and the slider 41 are designed with a dovetail shape. A groove handle 43 is fixedly provided on the outside of the storage box 4. A magnetic sheet B42 is fixedly provided on the inside of the top of the storage box 4. A magnetic sheet A16 is fixedly provided on the inside of the lower shell 1. The magnetic sheet A16 and the magnetic sheet B42 are magnetically attracted to each other.

[0023] The slider 41 at the bottom of the storage box 4 and the limiting groove 15 at the bottom of the inner side of the lower shell 1 form a sliding engagement. Since both adopt a dovetail structure, the slider can only slide along the length of the groove and cannot disengage in the direction perpendicular to the groove, thus achieving the sliding positioning of the storage box. Children can easily pull the storage box out or push it in from the inside of the lower shell by pulling the groove handle 43 on the outside of the storage box 4. When the storage box is completely pushed into the inside of the lower shell 1, the magnetic piece B42 on the top inner side of the storage box corresponds precisely with the magnetic piece A16 on the inner side of the lower shell 1 and generates a magnetic attraction, fixing the storage box in a closed state and preventing the storage box from sliding out on its own during the movement of the device.

[0024] Working principle and usage process of this utility model: The lower housing 1 serves as the main support structure of the device, bearing the weight of all components and providing installation and positioning functions. The upper housing 11, with its integrated design, provides a sealed and stable installation environment for the display screen 12, camera 13, and infrared emitter 14, preventing damage to delicate components from external dust and collisions. The camera 13 captures children's facial features in real time, such as the curvature of the corners of the mouth and the degree of eye opening and closing. The infrared emitter 14 emits infrared rays and receives reflected signals, calculating the distance between the device and the child. When the distance is too close, the processor triggers a prompt signal, and guidance content is displayed on the display screen 12. The memory metal spring 2 is initially taut and fixed to the outside of the lower housing 1, allowing the child to attach and detach the sticky note plate 3. The board 3 displays the child's daily study schedule, providing easy reminders of daily tasks. When external force is applied to the memory metal spring 2, it deforms and adheres tightly to the surface of the lower housing 1, where it is fixed in place. When the force is removed, the memory metal spring 2 returns to its taut state due to the properties of memory metal. Meanwhile, the storage box 4 is installed inside the lower housing 1 to store small items such as sticky notes and pens. The memory metal spring 2's combination of deformation adaptability and return-to-position stability provides a flexible mounting medium for the sticky note board 3. The detachable design of the sticky note board allows children to easily change the content, enhancing the device's interactivity and fun. The storage box 4 provides centralized storage for small items, preventing loss and cultivating children's tidying habits, thus enhancing the device's functionality. The companionship extends to guiding lifestyle habits. The memory metal spring 2 is mechanically fixed to the outer side of the lower housing 1 by the fixing block 21, ensuring that the spring will not shift as a whole when deformed by force. The arc-shaped groove 22 on the outer side of the spring provides it with a taut state. At the same time, when the memory metal spring 2 is bent and pressed against the outer surface of the lower housing 1 by external force, the magnetic ring A23 forms a magnetic attraction with the memory metal spring 2, making the memory metal spring 2 stick tightly to the surface of the lower housing 1, ensuring the stability of the memory metal spring 2 when stored. The magnetic ring B31 on the outer side of the sticky note plate 3 is attached to the arc-shaped groove 22 of the memory metal spring 2. The sticky note plate is fixed by the magnetic attraction between the magnetic ring B and the memory metal spring 2. Since the magnetic attraction allows for repeated disassembly, Features include easy removal of the sticky note board for drawing and writing, followed by reattachment to the spring clip. The whiteboard film design at the end of the sticky note board 3 away from the magnetic ring B31 allows for reusability; children can write and draw on the surface with whiteboard markers, and it can be reused after erasing, eliminating the need for frequent sticky note replacements. The slider 41 at the bottom of the storage box 4 slides into the limiting groove 15 on the inner bottom of the lower housing 1. Due to the dovetail structure of both, the slider can only slide along the length of the groove and cannot disengage perpendicular to it, achieving sliding positioning of the storage box. Children can easily pull the storage box out or push it in from the inside of the lower housing by pulling the groove handle 43 on the outside of the storage box 4. When the storage box is fully pushed into the inside of the lower housing 1...The magnetic plate B42 on the inner side of the top casing precisely corresponds to the magnetic plate A16 on the inner side of the lower casing 1, generating a magnetic attraction that secures the storage box in a closed state, preventing it from sliding out during device movement.
