[0002] With the increasing development of the Internet, today's digital media interaction methods are becoming more and more diverse. Large-screen intelligent interaction devices are applied in different environments, including teaching environments, conference environments, and outdoor environments. Through large-screen intelligent interaction devices, the function of human-computer interaction can be realized, facilitating remote interaction and information exchange.

[0003] In the prior art (publication number: CN217011050U), a digital media interaction device is disclosed. This technology includes: a housing, a main board box, and an audio-video mechanism. A placement bin is provided inside the housing, and the placement bin is configured to accommodate the audio-video mechanism. A main board box is also provided on the outer surface of one side of the housing, and an information processing main board is provided inside the main board box. The information processing main board is configured to communicate with the audio-video mechanism and / or other external devices through a communication interface opened on the main board box.

[0004] In the above technology, the main board box and the interaction screen are always exposed. When the device is installed outdoors for a long time to interact with people, the exposed main board box and interaction screen are easily impacted and collided by external forces, resulting in screen breakage and damage to main board components, affecting the normal use of the device. At the same time, when the main board box and the interaction screen are not in use, they are exposed for a long time, and the internal circuits and electronic components are directly exposed, easily contacting impurities such as water and dust, thereby reducing the service life of the device. Summary of the Invention

Another object of the present invention is to solve the problem that when the main board box and the interaction screen are not in use, they are exposed for a long time, easily contacting impurities such as water and dust, thereby reducing the service life of the device.

[0006] Technical Solution: A digital media interaction device includes a display screen. A storage box is fixedly connected to the lower surface of the display screen, and an interface panel is provided below the storage box.

[0007] A camera mechanism is provided above the front surface of the display screen, and sound playing mechanisms are symmetrically provided below the display screen.

[0008] Furthermore, a fixed frame is provided on the outer side of the display screen. Two plug-in vertical grooves are symmetrically formed on the inner side wall of the fixed frame. Guide plug strips are fixedly connected to both the left and right sides of the display screen. The outer side walls of the two guide plug strips are respectively slidably connected to the interiors of the two plug-in vertical grooves. A through docking groove is formed in the rear of the inner lower surface of the fixed frame, and the lower surface of the storage box passes through the docking groove.

[0009] Furthermore, through extending grooves are formed in both the left and right sides of the interior of the fixed frame and in front of the two plug-in vertical grooves. An adjustment groove is formed in the inner lower surface of the fixed frame and in front of the docking groove.

Limiting sliding plates are fixedly connected to the upper surfaces of the two adjustment blocks. Cover plates are fixedly connected to the opposite sides of the two limiting sliding plates. The opposite sides of the two cover plates respectively pass through the two extending grooves.

[0010] Furthermore, a transmission cavity is formed in the interior of the fixed frame and on the right side of the adjustment groove. The right end of the bidirectional threaded rod extends into the interior of the transmission cavity and is fixedly connected to a first bevel gear. A protective box is fixedly connected to the right side of the lower surface of the fixed frame. A control motor is fixedly connected to the upper surface of the interior of the protective box. A rotating rod is fixedly connected to the top end of the output shaft of the control motor. The top end of the rotating rod is rotatably connected to the upper surface of the interior of the transmission cavity through a rotating shaft. A second bevel gear is fixedly connected to the outer side wall of the rotating rod. The outer side wall of the second bevel gear is meshed with the outer side wall of the first bevel gear.

[0011] Furthermore, a first extrusion cavity is formed in the interior of the fixed frame and on the left side of the adjustment groove. A piston plate one is slidably connected to the interior of the first extrusion cavity. A contact plate is fixedly connected to the right side of the piston plate one. The right side of the contact plate is in contact with the left side of the limiting sliding plate on the left side of the interior of the fixed frame. A plurality of first springs are fixedly connected between the right side of the piston plate one and the right side of the interior of the first extrusion cavity. An air delivery pipe is fixedly connected to the left side of the interior of the first extrusion cavity.

[0012] Furthermore, a docking pipe is fixedly connected above the left side of the storage box. The end of the air delivery pipe away from the first extrusion cavity is threadedly connected to the inner side wall of the docking pipe. A through lifting opening is formed in the inner lower surface of the storage box. A piston plate two is slidably connected to the interior of the storage box. The upper surface of the interface panel passes through the lifting opening and is fixedly connected to the lower surface of the piston plate two.

[0013] Furthermore, second extrusion chambers are formed inside the fixed frame and between adjacent plugging vertical grooves and protruding grooves. The inside of each of the two second extrusion chambers is slidably connected with a movable plate. The front surfaces of the two movable plates are fixedly connected with inclined plates.

The sound playback mechanism can create a stereoscopic surround sound effect. Whether playing a blockbuster, music or having a video conference, users can obtain an immersive auditory experience, significantly improving the audio effect during the interaction process;

[0017] By controlling the motor to drive the rotating rod, the bidirectional threaded rod is driven to rotate through the meshing of the first bevel gear and the second bevel gear, so that the adjusting block drives the limiting sliding plate and the cover plate to move. When the device is not in use, the cover plate closes, completely covering the display screen, effectively blocking dust and water from contacting the display screen and the internal main board. At the same time, when the cover plate closes, the interface panel will be retracted into the storage box through the linkage of the first extrusion chamber, the first piston plate, the air delivery pipe, the butt joint pipe and the second piston plate. Moreover, the sealing plate on the lower surface of the interface panel further prevents dust and water vapor from entering the storage box, protecting the device in all directions and greatly improving the service life of the device;

[0018] When the two cover plates move relative to each other and close to protect the display screen, the two locking blocks are clamped into the two locking grooves by squeezing the two inclined plates, completing the locking of the display screen, preventing the display screen from being taken out when not in use and stored, thus effectively preventing the display screen from being accidentally taken out when not in use and in the storage state, avoiding the loss of the display screen and ensuring the safety of the device.

DETAILED DESCRIPTION

[0027] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Example

[0029] like Figure 1 , Figure 2 and Figure 5As shown, a fixed frame 6 is provided on the outer side of the display screen 1. Two insertion vertical slots 7 are symmetrically opened on the inner side wall of the fixed frame 6. Guide insertion strips 8 are fixedly connected to both the left and right sides of the display screen 1. The outer side walls of the two guide insertion strips 8 are respectively slidably connected to the interiors of the two insertion vertical slots 7. A through docking slot 9 is opened at the rear of the inner lower surface of the fixed frame 6. The lower surface of the storage box 2 passes through the docking slot 9;

[0030] First, install the fixed frame 6 at the display point for fixation. Then, insert the two provided guide insertion strips 8 into the interiors of the two insertion vertical slots 7, and the display screen 1 can be quickly inserted and fixed into the interior of the fixed frame 6. The storage box 2 and the interface panel 3 pass through the docking slot 9. At the same time, when the display screen 1 fails, maintenance personnel can easily disassemble the display screen 1 from the fixed frame 6 to repair the display screen 1, avoiding the increase in maintenance difficulty due to the complex structure of the overall device being difficult to disassemble, greatly improving the maintenance efficiency, reducing the maintenance cost. In addition, when transporting or needing to replace the display screen 1 to adapt to different usage scenarios and requirements, the detachable design also facilitates the handling of the device and the replacement of components, enhancing the flexibility and applicability of the device.

[0031] As Figure 1 As shown, a digital media interaction device is provided, including a display screen 1. A storage box 2 is fixedly connected to the lower surface of the display screen 1. An interface panel 3 is provided below the storage box 2. A camera mechanism 4 is provided above the front surface of the display screen 1. Sound playback mechanisms 5 are symmetrically provided below the display screen 1;

[0032] Through the provided display screen 1, various digital contents can be clearly presented. The interface panel 3 is equipped with multiple interfaces. For example, the USB interface is convenient for connecting a storage device to read data, and the HDMI interface can be connected to a high-definition playback device, greatly expanding the connection possibilities between the device and external devices and enriching the content input sources. The camera mechanism 4 above the display screen 1 can meet the needs of video calls, facilitating users to communicate remotely, and can also be used to implement the face recognition function to ensure the security of device use and be applied to somatosensory interactive games to add interactive fun. The sound playback mechanisms 5 below the display screen 1 can create a stereoscopic surround sound effect. Whether playing a blockbuster movie, music or having a video conference, users can obtain an immersive auditory experience, significantly enhancing the audio effect during the interaction process.

[0033] As Figure 2As shown in the figure, through slots 10 are provided on the left and right sides inside the fixed frame 6 and in front of the two plug-in vertical slots 7. An adjustment slot 11 is provided on the lower surface inside the fixed frame 6 and in front of the docking slot 9. The left side inside the adjustment slot 11 is rotatably connected to a bidirectional threaded rod 12 through a rotating shaft. Adjustment blocks 19 are symmetrically threadedly connected to the outer side wall of the bidirectional threaded rod 12. Limiting sliding plates 20 are fixedly connected to the upper surfaces of the two adjustment blocks 19. Cover plates 21 are fixedly connected to the opposite sides of the two limiting sliding plates 20. The opposite sides of the two cover plates 21 respectively pass through the two through slots 10. A transmission cavity 13 is provided inside the fixed frame 6 and on the right side of the adjustment slot 11. The right end of the bidirectional threaded rod 12 extends into the transmission cavity 13 and is fixedly connected to a bevel gear one 14. A protective box 15 is fixedly connected to the right side of the lower surface of the fixed frame 6. A control motor 16 is fixedly connected to the upper surface inside the protective box 15. The top end of the output shaft of the control motor 16 is fixedly connected to a rotating rod 17. The top end of the rotating rod 17 is rotatably connected to the upper surface inside the transmission cavity 13 through a rotating shaft. A bevel gear two 18 is fixedly connected to the outer side wall of the rotating rod 17. The outer side wall of the bevel gear two 18 is meshed with the outer side wall of the bevel gear one 14;

[0034] When the display screen 1 needs to be protected during use, by starting the control motor 16, the control motor 16 drives the rotating rod 17 to rotate. The rotation of the rotating rod 17 causes the bevel gear two 18 to rotate accordingly. Since the bevel gear two 18 is meshed with the bevel gear one 14, the bevel gear one 14 will also rotate, enabling the bidirectional threaded rod 12 to rotate within the adjustment slot 11. At this time, the two adjustment blocks 19 will move towards each other on the bidirectional threaded rod 12. Thus, the two limiting sliding plates 20 will move together with the two adjustment blocks 19. The two cover plates 21 respectively pass through the through slots 10 on both sides of the fixed frame 6 and gradually move towards the display screen 1 until the two cover plates 21 completely cover the front of the display screen 1, completing the protection of the display screen 1, effectively protecting the display screen 1 from external physical damage when not in use, such as preventing dust and debris from falling on the surface of the display screen 1 and affecting the display effect, and preventing the screen from cracking due to collision and scratching, prolonging the service life of the display screen 1. At the same time, it can also improve the overall aesthetics and safety of the device, reducing potential safety hazards caused by the exposure of the display screen 1. If the display screen 1 needs to be used, by controlling the control motor 16 to reverse the rotation of the rotating rod 17, the two cover plates 21 can be made to slide away from each other, thus exposing the display screen 1 for use.

[0035] Such as Figure 4 、 Figure 5 and Figure 7As shown in the figure, a second extrusion cavity 30 is provided inside the fixed frame 6 and between the adjacent insertion vertical grooves 7 and the protruding grooves 10. A movable plate 31 is slidably connected to the inside of each of the two second extrusion cavities 30. Oblique plates 32 are fixedly connected to the front surfaces of the two movable plates 31. A plurality of second springs 33 are fixedly connected between the rear surfaces of the two movable plates 31 and the rear inner surfaces of the two second extrusion cavities 30 respectively. Grooves 34 are provided on the rear surfaces of the two cover plates 21. The front surfaces of the two oblique plates 32 extend into the two grooves 34 respectively. Sliding cavities 35 are provided inside the fixed frame 6 and behind the two second extrusion cavities 30. The interiors of the two sliding cavities 35 are respectively communicated with the interiors of the two second extrusion cavities 30. Sliding plates 36 are slidably connected to the interiors of the two sliding cavities 35. Locking blocks 37 are fixedly connected to the rear surfaces of the two sliding plates 36. Locking grooves 38 are provided on the front surfaces of the two guiding inserts 8;

[0036] When the two cover plates 21 are moved towards the display screen 1 and gradually closed by controlling the motor 16, as the two cover plates 21 move, under the push of the cover plates 21, the oblique plates 32 will disengage from the two grooves 34 and be squeezed, so that the movable plates 31 can slide backward in the second extrusion cavities 30, compressing the plurality of second springs 33. While the movable plates 31 slide backward, the sliding plates 36 will slide backward under the drive of the movable plates 31. When the sliding plates 36 slide backward, the locking blocks 37 fixed to their rear surfaces will also move backward accordingly, and then the locking blocks 37 will be snapped into the locking grooves 38 to complete the locking of the display screen 1, preventing the display screen 1 from being taken out when not in use and stored, thus effectively preventing the display screen 1 from being accidentally taken out when not in use and in the stored state, avoiding the loss of the display screen 1, and ensuring the safety of the device.

[0037] As Figure 3 and Figure 6 shown in the figure, a first extrusion cavity 22 is provided inside the fixed frame 6 and on the left side of the adjustment groove 11. A piston plate 23 is slidably connected to the inside of the first extrusion cavity 22. A contact plate 24 is fixedly connected to the right side of the piston plate 23. The right side of the contact plate 24 is in contact with the left side of the left limit sliding plate 20 inside the fixed frame 6. A plurality of first springs 25 are fixedly connected between the right side of the piston plate 23 and the right inner side of the first extrusion cavity 22. An air delivery pipe 26 is fixedly connected to the left side inside the first extrusion cavity 22. A docking pipe 27 is fixedly connected above the left side of the storage box 2. The end of the air delivery pipe 26 far from the first extrusion cavity 22 is threadedly connected to the inner side wall of the docking pipe 27. A through-type lifting opening 28 is provided on the lower surface inside the storage box 2. A piston plate 29 is slidably connected to the inside of the storage box 2. The upper surface of the interface panel 3 passes through the lifting opening 28 and is fixedly connected to the lower surface of the piston plate 29;

[0038] When the two cover plates 21 are moved toward each other and gradually closed by controlling the motor 16, the limiting slide plate 20 located on the left side of the fixed frame 6 will cancel the contact with the resistance plate 24 when it moves to the left, so the piston plate 1 23 will slide to the right in the extrusion chamber 1 22 through the rebound of the multiple springs 1 25. When the piston plate 1 23 slides to the right, the gas in the storage box 2 enters the interior of the internal extrusion chamber 1 22 through the gas pipe 26, thereby generating an upward attraction for the piston plate 29, that is, under the action of the gas, the piston plate 29 drives the interface panel 3 to move upward and retract into the interior of the storage box 2. When the control motor 16 is reversed, the two cover plates 21 begin to When they move away from each other and gradually open, the limiting slide plate 20 located on the left side of the fixed frame 6 will move outward until it squeezes the resistance plate 24, thereby controlling the piston plate 1 23 to slide to the left and compressing multiple springs 1 25, so that the interface panel 3 can be driven to move downward through the piston plate 29 and extend to the bottom of the storage box 2, so that the user can connect external devices and perform other operations. Then, when the interface panel 3 is not in use, it can be retracted into the storage box 2, which can effectively prevent the interface panel 3 from being damaged by dust, water vapor, external force collision and other factors, thereby extending the service life of the interface panel 3 and reducing equipment failures and maintenance costs caused by interface damage.

[0039] like Figure 1 and Figure 3 As shown, a sealing plate 39 is fixedly connected to the lower surface of the interface panel 3;

[0040] When the interface panel 3 is retracted into the storage box 2, the sealing plate 39 can fit tightly against the bottom opening edge of the storage box 2, thereby further blocking external dust from entering the storage box 2, preventing dust from accumulating on the jacks and other components of the interface panel 3, and preventing problems such as poor interface contact or short circuit due to dust accumulation, thereby extending the service life of the interface panel 3 and the entire device.

[0041] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
