Description

Technical Field

[0001] The present invention relates to the technical field of art display, and particularly to a playback device for digital media art display. Background Art

[0002] Digital media is a new form of communication that is based on digital technology and Internet platforms and integrates various media forms such as text, images, audio, and video. With its advantages of strong interactivity, fast transmission speed, and wide coverage, it has greatly enriched people's information acquisition channels and entertainment lives.

[0003] Digital media art display vividly presents a rich variety of digital content to the audience through advanced playback technology and creative design. It uses modern media such as high-definition screens, projection devices, and interactive devices to display art works in the forms of dynamic images, virtual reality, and augmented reality, bringing immersive viewing experiences to the audience.

[0004] Existing playback devices are limited by fixed-mounted displays, not only having poor mobility, seriously restricting the diversity of usage scenarios, but also the design of a single display screen limits the number of art works displayed each time, making it difficult to fully display the richness and diversity of digital media art, thus affecting the overall display effect and the viewing experience of the audience. Therefore, a playback device for digital media art display is proposed. Summary of the Invention

[0005] The purpose of the present invention is to solve the drawbacks in the prior art that the playback device is limited by a fixed-mounted display, not only having poor mobility, seriously restricting the diversity of usage scenarios, and the design of a single display screen limits the number of art works displayed each time, making it difficult to fully display the richness and diversity of digital media art, and to propose a playback device for digital media art display.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A playback device for digital media art display includes a box body. A plurality of wheels are movably connected to the bottom of the box body. An expansion component is arranged on the box body. The expansion component includes a first rotating rod rotatably connected inside the box body, and a second bottom plate, a first bottom plate, and a rack movably connected outside the box body. The rotation of the first rotating rod drives the first bottom plate and the second bottom plate to unfold at a certain angle, and the movement of the rack drives the first bottom plate to unfold outward to be flush with the second bottom plate. Display screens are fixedly connected to the outer sides of the first bottom plate and the second bottom plate. A stability component is arranged on the box body. The stability component includes a plurality of rubber blocks and a movable plate movably connected inside the box body. The forward and reverse rotation of the first rotating rod drives the movable plate to move up and down. The downward movement of the movable plate drives the plurality of rubber blocks to squeeze the wheels to restrict the wheels.

[0008] The above technical solution further includes:

[0009] Inside the box body, slide rails are symmetrically and fixedly connected. A lid is slidably connected to the outer sides of the two slide rails. A support rod is movably connected to the outer side of the lid. The groove in the slide rail restricts the sliding position of the lid.

[0010] A first motor is fixedly connected to the upper part of the first motor. The end of the output shaft of the first motor is fixedly connected to the first rotating rod. A threaded rod is fixedly connected to the end of the first rotating rod away from the first motor. The start of the first motor drives the first rotating rod to rotate, and the rotation of the first rotating rod causes the threaded rod to rotate accordingly.

[0011] The movable plate is in threaded connection with the threaded rod. A limiting rod is fixedly connected inside the box body. The movable plate is movably connected to the limiting rod. The forward and reverse rotation of the threaded rod drives the movable plate to move up and down on the limiting rod.

[0012] One side of the movable plate away from the first motor is fixedly connected to a rubber block. The rubber block is movably connected to a wheel. The threaded rod drives the rubber block to move up and down, so that the rubber block moving up and down fixes and releases the fixing effect on the wheel.

[0013] A support plate is fixedly connected to the outer side of the first rotating rod. A second motor is fixedly connected to the upper part of the support plate. The end of the output shaft of the second motor is fixedly connected to a second rotating rod. The rotation of the first rotating rod drives the support plate to rotate, and the support plate drives the display screen to rotate accordingly.

[0014] Fixing blocks are symmetrically and fixedly connected to one side of the support plate close to the second motor. The fixing blocks are fixedly connected to the second rotating rod. A gear is fixedly connected to the outer side of the second rotating rod. The start of the second motor drives the gear and the second rotating rod to rotate.

[0015] L-shaped slide rails are symmetrically and fixedly connected to the upper part of the support plate. Sliders are slidably connected inside the two L-shaped slide rails. A connecting rod is fixedly connected to the upper part of the slider. The slider slides inside the L-shaped slide rail and the connecting rod is located at the center position of the slider.

[0016] The connecting rod is movably connected to a rack. The rack is meshed with the gear. Second pulleys are symmetrically and fixedly connected to the outer side of the slider. The two second pulleys are slidably connected to the L-shaped slide rail. The rack moves left and right through the rotation of the gear, and the left and right movement of the rack drives the slider to move accordingly.

[0017] The bottom of the slider is symmetrically and fixedly connected with first pulleys, and the two first pulleys are slidably connected with the L-shaped slide rail. One side of the slider close to the first pulley is movably connected with a fixed plate, and the fixed plate is fixedly connected with the first bottom plate. The slider drives the first bottom plate to expand outwards and inwards through the connection of the fixed plate.

[0018] The present invention has the following beneficial effects:

[0019] 1. In the present invention, the rotation of the first rotating rod in the stability component drives the display screen to expand outwards, and the rotation of the first rotating rod drives a plurality of rubber blocks to press down on the wheels, ensuring the stable locking of the wheels in the expanded state of the display screen, effectively preventing accidental sliding or shaking, and greatly improving the structural stability and viewing safety of the entire playback device.

[0020] 2. In the present invention, the first bottom plate in the expansion component expands outwards to be flush with the second bottom plate, providing a wider and more variable display space, ensuring the flatness and unity of the display screen in the expanded state, fully demonstrating the richness of digital media art, and driving the display screen to contract in the box through the rotation of the first rotating rod, improving the safety of the display screen.

The rotation of the first rotating rod 8 drives the first bottom plate 6 and the second bottom plate 7 to unfold at 90 degrees, and the movement of the rack 20 drives the first bottom plate 6 to unfold outward to be flush with the second bottom plate 7. Display screens 4 are fixedly connected to the outsides of the first bottom plate 6 and the second bottom plate 7. A stability component is provided on the box body 1. The stability component includes a plurality of rubber blocks 12 and a movable plate 13 movably connected inside the box body 1. The forward and reverse rotation of the first rotating rod 8 drives the movable plate 13 to move up and down. The downward movement of the movable plate 13 drives the plurality of rubber blocks 12 to squeeze the wheels 11 to restrict the wheels 11.

[0032] Two slide rails 9 are symmetrically and fixedly connected inside the box body 1. A lid 2 is slidably connected to the outsides of the two slide rails 9. A support rod 3 is movably connected to the outside of the lid 2. The groove in the slide rail 9 restricts the sliding position of the lid 2.

[0033] A first motor 5 is fixedly connected to the upper part of the first motor 5. A fixed connection is provided between the end of the output shaft of the first motor 5 and the first rotating rod 8. A threaded rod 10 is fixedly connected to the end of the first rotating rod 8 away from the first motor 5. The start of the first motor 5 drives the first rotating rod 8 to rotate, and the rotation of the first rotating rod 8 causes the threaded rod 10 to rotate accordingly.

[0034] The movable plate 13 is threadedly connected to the threaded rod 10. A limiting rod 14 is fixedly connected inside the box body 1. The movable plate 13 is movably connected to the limiting rod 14. The forward and reverse rotation of the threaded rod 10 drives the movable plate 13 to move up and down along the limiting rod 14.

[0035] A fixed connection is provided between the side of the movable plate 13 away from the first motor 5 and the rubber block 12. The rubber block 12 is movably connected to the wheel 11. The threaded rod 10 drives the rubber block 12 to move up and down, so that the moving rubber block 12 fixes and releases the fixing effect on the wheel 11.

[0036] In this embodiment, when the device needs to be used, the box body 1 is pushed so that the box body 1 adjusts the playing position through a plurality of wheels 11, and the side of the box body 1 close to the first motor 5 faces the viewing position. At this time, the cover 2 is pulled so that the cover 2 slides to the rearmost side of the box body 1. The support rod 3 on the side of the cover 2 contacts the ground, improving the stability of the overall device. By starting the first motor 5, the first rotating rod 8 is driven to rotate. At this time, the rotation of the first rotating rod 8 drives the threaded rod 10 to rotate. The rotation of the threaded rod 10 drives the movable plate 13 to slide downward along the limiting rod 14. The downward sliding of the movable plate 13 drives a plurality of rubber blocks 12 to press downward on the wheels 11, restricting and fixing the wheels 11, making the display screen 4 more stable during viewing. When the device does not need to be used, the reverse rotation of the first rotating rod 8 drives the threaded rod 10 to rotate accordingly. The rotating threaded rod 10 drives the movable plate 13 to move upward. The moving movable plate 13 drives a plurality of rubber blocks 12 away from the wheels 11, releasing the restriction on the wheels 11, and the overall device can be moved.

[0037] Embodiment Two

[0038] As Figures 1-7 shown, on the basis of Embodiment One, a support plate 15 is fixedly connected to the outside of the first rotating rod 8. The upper part of the support plate 15 is fixedly connected to a second motor 16. The end of the output shaft of the second motor 16 is fixedly connected to a second rotating rod 19. The rotation of the first rotating rod 8 drives the support plate 15 to rotate, and the support plate 15 drives the display screen 4 to rotate accordingly.

[0039] Symmetrically fixed connections are provided on the side of the support plate 15 close to the second motor 16 with fixing blocks 21. The fixing blocks 21 are fixedly connected to the second rotating rod 19. A gear 18 is fixedly connected to the outside of the second rotating rod 19. The start of the second motor 16 drives the gear 18 and the second rotating rod 19 to rotate.
