When the side screens rotate forward to integrate with the main screen, or rotate backward to form a triangular arrangement with the main screen, the display effect of the digital audiovisual components can be adjusted in various ways according to user needs, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a digital audio-visual integrated device for Chinese language and culture, comprising a support base, wherein the support base is provided with digital audio-visual components for multi-view viewing; The digital audiovisual component includes a main screen and two side screens located on the top of the support base. The main screen is installed on the top front end of the support base, and the two side screens are rotatably connected to the rear ends of the main screen. Each of the two side screens has a touch panel mounted on the top of the support base on one side of the bottom edge. A first tactile switch is embedded on the side of the touch panel near the side screen. A fan, an airflow sensor, and an alarm are mounted on the side of the two touch panels that are close to each other. The fan is located between the airflow sensor and the alarm. A distance sensor and a reflector are respectively installed at the top of the two side screens, with the distance sensor located on one side of the reflector.

[0006] In a preferred embodiment, fixed brackets are installed on the rear sides of both ends of the main screen, and fixed shafts are installed inside the fixed brackets via rotating shafts. Fixed plates for connecting the side screens are sleeved on the outside of the fixed shafts.

[0007] In a preferred embodiment, a cavity is provided inside the front end of the support base, and two linkage shafts are provided inside the cavity. Each linkage shaft has a pulley sleeved on the bottom end of the two linkage shafts. A belt is provided between the two pulleys, and the two pulleys are driven by the belt. The belt has a figure-eight cross section. The top end of the linkage shaft passes through the support base and the fixed bracket in sequence and is fixed together with the bottom end of the fixed shaft. A servo motor is installed at the bottom of the support base, and the output shaft of the servo motor extends into the cavity and is fixed to the bottom end of one of the linkage shafts.

[0008] In a preferred embodiment, the support base has a base at the bottom, and the base has a storage groove at the top. Inside the storage groove is a sleeve that fits over the bottom of the support base, and the outer side of the sleeve corresponding to the main screen and the two side screens is machined with a writing surface.

[0009] In a preferred embodiment, two mirror-distributed connecting brackets are installed inside the bottom end of the housing. The top ends of both connecting brackets extend to the top of the support base, and the same connecting base is installed on the top of the two connecting brackets. A threaded rod is installed on the side of the top of the support base corresponding to the connecting base through a bearing. The connecting base is sleeved on the outside of the threaded rod, and the inner wall of the connecting base is threadedly connected to the outside of the threaded rod. A drive motor is installed on one side of the bottom of the support base corresponding to the threaded rod, and the output shaft of the drive motor passes through the support base and is fixed together with the bottom end of the threaded rod.

[0010] In a preferred embodiment, the connecting bracket is provided with positioning seats on both the front and rear sides of its bottom end. The bottom end of the positioning seat is fixed to the bottom of the inner cavity of the storage groove, and the top end of the positioning seat is equipped with an electric push rod for lifting the support seat.

[0011] In a preferred embodiment, two spaced pressure plates are provided at the bottom of both ends of the support base, and pressure columns are installed at the bottom of the pressure plates, with the bottom ends of the pressure columns fixed together with the bottom of the inner cavity of the storage groove.

[0013] In a preferred embodiment, the base is equipped with a plurality of self-locking casters at its bottom, and the plurality of self-locking casters are evenly spaced apart.

[0014] The technical effects and advantages of this invention are as follows: 1. Two pulleys are driven by a figure-eight belt, which can drive the two side screens to rotate synchronously forward or backward via corresponding linkage shafts. When the side screens rotate forward, they are integrated with the main screen. When the side screens rotate backward, they are arranged in a triangle with the main screen. This allows for various adjustments to the display effect of the digital audiovisual components according to usage needs, improving practicality and functional diversity. 2. By matching the distance sensor with the reflector, the distance data of the two side screens after they rotate forward can be monitored. At the same time, the effect of the side screens rotating backward can be judged by the contact between the touch switch and the side screen. When the distance data does not meet the standard or the touch switch is not activated, the alarm will warn that the rotation adjustment of the side screen is abnormal and needs to be adjusted in time to avoid damage due to excessive rotation or poor rotation effect that fails to effectively display Chinese language and culture. 3. The airflow rate between the side screen and the main screen after folding is monitored by an airflow sensor. When the monitored data does not reach the effective heat dissipation, the fan runs to accelerate the airflow, thereby avoiding the accumulation of heat due to low airflow rate and ensuring the operational stability of the side screen and the main screen. 4. The drive motor drives the threaded rod to rotate, which in turn drives the connecting bracket, which is limited by the support seat, to move up and down. The connecting bracket then drives the shell to be fitted onto the outside of the side screen and the main screen, thus achieving the effect of shielding and protecting the main screen and the side screen, preventing damage to the side screen and the main screen from collisions and impacts. At the same time, the writing surface on the outside of the shell allows for separate explanation of a certain section when displaying Chinese language and culture, thereby improving practicality and functional versatility.

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] Refer to the instruction manual appendix Figure 1-7 The present invention provides a digital audio-visual integrated device for Chinese language and culture, including a support base 1, wherein the support base 1 is provided with digital audio-visual components for multi-view viewing. The digital audiovisual component includes a main screen 2 and two side screens 3 mounted on the top of the support base 1. The main screen 2 is mounted on the top front end of the support base 1, and the two side screens 3 are rotatably connected to the rear ends of the main screen 2. Each of the two side screens 3 has a touch plate 4 mounted on the top of the support base 1 on the side of its bottom end that is close to each other. A first tactile switch 5 is embedded on the side of the touch plate 4 that is close to the side screen 3. A fan 6, an airflow sensor 7, and an alarm 8 are mounted on the side of the two touch plates 4 that are close to each other. The fan 6 is located between the airflow sensor 7 and the alarm 8. A distance sensor 9 and a reflector 10 are respectively mounted on the top of the two side screens 3. The distance sensor 9 is located on one side of the reflector 10.

[0019] In use, the operator operates the handle 31 to move the base 19, supported by the self-locking caster wheel 32, to a suitable position. Then, according to the actual usage requirements, the servo motor 18 is started. The servo motor 18 drives the two pulleys 16 driven by the belt 17 to rotate. Since the belt 17 is in a figure-eight shape to drive the two pulleys 16, the two pulleys 16 rotate in opposite directions. Thus, when the two pulleys 16 drive the fixed shaft 12 to rotate through the corresponding linkage shaft 15, the fixed shaft 12 can drive the side screen 3 to rotate forward or backward through the fixed plate 13. When the two side screens 3 rotate forward and move to the sides of the main screen 2 respectively, the distance sensors 9 on the two side screens 3 correspond to the reflector 10. When the distance data between the distance sensors 9 and the reflector 10 is the set value, the servo motor 18 stops running to ensure the stability of the combination of the side screens 3 and the main screen 2. At the same time, the combination of the side screens 3 and the main screen 2 can better display Chinese language and culture. When the two side screens 3 rotate backward and are arranged in a triangle with the main screen 2, the side screens 3 contact the touch switch 5 on the touch panel 4. The touch switch 5 starts the fan 6 and the airflow sensor 7 and turns off the servo motor 18. The airflow sensor 7 monitors the airflow rate between the side screens 3 and the main screen 2. When the monitoring data does not reach the effective heat dissipation, the fan 6 runs to accelerate the airflow, thereby avoiding the situation where the airflow rate is low and heat accumulates, ensuring the operational stability of the side screens 3 and the main screen 2. At the same time, the side screens 3 and the main screen 2 are folded to display Chinese language and culture from multiple perspectives. When the distance data between the ranging sensor 9 and the reflector 10 does not reach the set value, and the touch switch 5 does not contact the side screen 3, the rotation angle of the side screen 3 is not completed and the alarm 8 issues a warning, thereby ensuring the rotation stability and accuracy of the side screen 3 and avoiding over-rotation or poor rotation effect.

[0020] When driving the above structure, it requires the assistance of devices such as servo motor 18, for example... Figure 4 and 6 As shown, fixed brackets 11 are installed on the rear sides of both ends of the main screen 2, and fixed shafts 12 are installed inside the fixed brackets 11 and movably connected by a rotating shaft. A fixed plate 13 for connecting the side screen 3 is sleeved on the outside of the fixed shaft 12. A cavity 14 is opened inside the front end of the support base 1. Two linkage shafts 15 are provided inside the cavity 14. Pulleys 16 are sleeved on the bottom of the two linkage shafts 15. A belt 17 is provided between the two pulleys 16 and the two pulleys 16 are driven by the belt 17. The belt 17 has an 8-shaped cross section. The top of the linkage shaft 15 passes through the support base 1 and the fixed bracket 11 in sequence and is fixed to the bottom of the fixed shaft 12. A servo motor 18 is installed at the bottom of the support base 1, and the output shaft of the servo motor 18 extends into the cavity 14 and is fixed to the bottom of one of the linkage shafts 15.

[0021] In use, because the fixed shaft 12 is movably connected to the fixed bracket 11 through the bearing, the fixed plate 13 on the fixed shaft 12 can drive the side screen 3 to rotate. The bottom end of the fixed shaft 12 rotates with the pulley 16 through the linkage shaft 15, so that the servo motor 18 can drive the two pulleys 16 driven by the belt 17 to run. Since the belt 17 is in the shape of an 8, the two pulleys 16 rotate in opposite directions, thereby achieving the effect of synchronously rotating the two side screens 3 inward or outward.

[0022] To better showcase and engage with Chinese language and culture, real-time explanations of the Chinese language and culture are necessary, such as... Figure 1-3 As shown, the support base 1 has a base 19 at the bottom, and a storage groove 20 is opened at the top of the base 19. The storage groove 20 has a sleeve 21 that is fitted onto the outside of the bottom end of the support base 1. The outer side of the sleeve 21 corresponding to the main screen 2 and the two side screens 3 is processed with a writing surface 22. A handle 31 is installed on the rear side of the top of the base 19 for convenient movement of the digital audio-visual components. Multiple self-locking universal wheels 32 are installed at the bottom of the base 19, and the multiple self-locking universal wheels 32 are evenly spaced apart.

[0023] The writing surface 22 on the outside of the casing 21 corresponds to the main screen 2 and the side screen 3, allowing staff to explain or interact with the content on the writing surface 22 individually, thus enhancing the display of Chinese language and culture and expanding the functionality. At the same time, the handle 31 and the self-locking casters 32 make it easy for staff to hold the handle 31 and move the base 19 to a suitable position for display and use.

[0024] At the same time, to prevent damage to the main screen 2 and side screen 3 from collisions and impacts, it is necessary to adjust the casing 21 to protect the digital audiovisual components, such as... Figure 1-3 As shown, two mirror-distributed connecting brackets 23 are installed inside the bottom end of the housing 21. The top ends of both connecting brackets 23 extend to the top of the support base 1, and the same connecting seat 24 is installed on the top of the two connecting brackets 23. A threaded rod 25 is installed on the top of the support base 1 corresponding to the connecting seat 24 via a bearing. The connecting seat 24 is sleeved on the outside of the threaded rod 25, and the inner wall of the connecting seat 24 is threadedly connected to the outside of the threaded rod 25. A drive motor 26 is installed on the bottom of the support base 1 corresponding to the threaded rod 25, and the output shaft of the drive motor 26 passes through the support base 1 and is fixed together with the bottom end of the threaded rod 25.

[0025] When in use, the drive motor 26 is started to drive the threaded rod 25 to rotate. The threaded rod 25 then drives the connecting bracket 23, which is limited by the support seat 1, to move upward. The connecting bracket 23 then drives the shell 21 to move upward in sync, so that the shell 21 is gradually fitted onto the outside of the side screen 3 and the main screen 2, achieving the effect of all-round protection for the side screen 3 and the main screen 2 after folding and storing, avoiding damage to the side screen 3 and the main screen 2 from collisions, and ensuring the performance of the side screen 3 and the main screen 2.

[0026] To better meet the needs of different users, the height of the digital audiovisual components needs to be adjustable, such as... Figure 3 and 4 As shown, the connecting bracket 23 has positioning seats 27 on both the front and rear sides at the bottom. The bottom of the positioning seat 27 is fixed to the bottom of the inner cavity of the storage groove 20. The top of the positioning seat 27 is equipped with an electric push rod 28 for lifting the support seat 1. The bottom of both ends of the support seat 1 is provided with two spaced pressure plates 29. The bottom of the pressure plates 29 is equipped with pressure columns 30. The bottom of the pressure columns 30 is fixed to the bottom of the inner cavity of the storage groove 20.

[0027] In use, the electric push rod 28 is supported and fixed by the positioning seat 27. The connection between the positioning seat 27 and the support seat 1 allows the electric push rod 28 to push the support seat 1 upward when it is extended. The support seat 1 then drives the main screen 2 and the side screen 3 upward, thereby achieving the effect of height adjustment of the main screen 2 and the side screen 3 to meet the needs of different users. At the same time, the pressure plate 29 and the pressure column 30 support the support seat 1 when it is not in use, enhancing the stability of the support seat 1.

[0028] In conclusion, the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
