Description

Technical Field

[0001] The present invention belongs to the technical field of television screens, and in particular refers to a digital display device for cultural media. Background Art

[0002] Cultural media is an extension of the media industry. It uses modern communication methods and media to spread culture and communicate between different cultures. Electronic screens are usually used as display carriers to improve the communication effect. At present, the display screens using naked-eye 3D technology can provide a more three-dimensional sense, attract the attention of the crowd, and improve the display and publicity effects. The principle of the current naked-eye 3D technology is to project the pixel points corresponding to the left and right eyes into the left and right eyes respectively, and use the parallax principle to produce a three-dimensional image. Using two display screens and a specific background structure can improve the display effect, but the problem is that the display screen is fixed and its best observation effect exists within a specific angle range, that is, not all viewers can get the best 3D display effect. Summary of the invention

[0003] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a digital display device for cultural media, which has an automatic adjustment function compared to traditional promotional display screens, produces better naked-eye 3D viewing effects, and is more attractive and has a better promotional effect.

[0004] The technical solution adopted by the present invention is as follows: The present invention provides a digital display device for cultural media, including a display stand, a display screen and an adjustment stand. The display stand is provided with a transposition slide rail, and the transposition slide rail is composed of two mutually perpendicular and connected linear slide rails one and two. The transposition slide rail is an L-shaped slide rail. The display screen is provided with two, including display screen one and display screen two, which are arranged in the transposition slide rail, and can be moved and adjusted on the transposition slide rail to adjust to a more suitable viewing angle. The adjustment stand is provided with an adjustment mechanism, and the display stand is arranged on the adjustment mechanism.

[0005] Furthermore, two sliders are provided in the transposition slide rail, including a driving slider and a driven slider. The driving slider is rotatably connected to one end of display screen one, and a pulley is provided at the other end of display screen one. The driven slider is rotatably connected to one end of display screen two, and a pulley is provided at the other end of display screen two. The pulley slides in the transposition slide rail. A conversion rod is connected between the driving slider and the driven slider. The conversion rod is hinged to the two sliders, and a pushing cylinder is hinged on the driving slider, and an extension end is provided on the conversion rod at one end on the driving slider, and the telescopic end and the extension end of the pushing cylinder are hinged.

[0006] Furthermore, the driving slider only slides in the first linear slide rail, the driven slider only slides in the second linear slide rail, and the pulley can slide in the entire transposition slide rail.

[0007] The push cylinder starts, and then pushes the conversion rod to rotate around the driving slider, and the other end of the conversion rod pushes the driven slider to slide, and because the conversion rod connects the driving slider and the driven slider, the driven slider also pulls the driving slider to slide. Then the display screen 1 and the display screen 2 move in the transposition slide rail at the same time, so that the display screen 1 and the display screen 2 can be moved to the linear slide rail 1 or the linear slide rail 2 at the same time, and the two are spliced ​​into a larger display screen; or the display screen 1 and the display screen 2 are arranged in the linear slide rail 1 and the linear slide rail 2 respectively, and the two form an L-shaped screen.

[0008] Furthermore, the adjustment mechanism includes a worm wheel, a worm, a worm wheel frame, a worm frame, motor one and motor two, a support frame is provided on the adjustment platform, the worm is rotatably arranged on the support frame, the worm frame is rotatably arranged on the support frame, an extension shaft is provided at one end of the worm, the extension shaft passes through the support frame, one end of the worm frame is a swivel, the swivel is rotatably arranged on the support frame, and the extension shaft passes through the swivel.

[0009] The worm frame is provided with a sleeve ring, the worm wheel is rotatably arranged in the sleeve ring, the worm wheel and the worm are meshed, the worm wheel frame is rotatably arranged on the sleeve ring, the worm wheel frame and the worm wheel are coaxial, the motor 1 is connected to the worm frame, the driving end of the motor 2 is connected through the rotating ring and the extension shaft of the worm, and the display stand is arranged on the worm wheel frame.

[0010] The rotation direction of the worm gear frame is different from that of the worm gear frame.

[0011] When the first motor is started, it drives the worm frame to rotate, and the worm gear frame also rotates; when the second motor is started, it drives the worm to rotate, and then drives the worm gear to rotate, and then the worm gear frame rotates. And the two rotation directions are two dimensions respectively, which can realize the multi-dimensional angle adjustment of the display stand.

[0012] Furthermore, a face recognition system is provided on the display screen, and is controllably connected to the push cylinder and the regulating mechanism.

[0013] The facial recognition system can identify the orientation of the viewing crowd, and then control the position and angle of the display screen. The display screen layout can be adjusted by pushing the cylinder, and the angle of the display screen can be adjusted by the adjustment mechanism, thereby providing the best viewing angle for the crowd and producing the best 3D visual experience.

[0014] Furthermore, since the width of the two display screens after splicing is equivalent to a linear slide rail, when the two display screens are in a perpendicular state to each other, that is, when the two display screens are arranged in two linear slide rails, a large area of ​​empty space will be generated. Therefore, a folding sub-screen is hingedly provided on the two display screens, and a folding hydraulic cylinder is hingedly provided on the display screen, and the telescopic end of the folding hydraulic cylinder is hinged to the folding sub-screen.

[0015] When the two display screens are perpendicular to each other, the folding sub-screen is unfolded by controlling the folding hydraulic cylinder to fill the empty space. The four display screens can completely fill the entire slide rail space, thereby expanding the visual range and improving the display effect.

[0016] Furthermore, a protective cover is provided outside the adjusting mechanism.

[0017] The beneficial effects achieved by the present invention using the above structure are as follows: This solution provides a digital display device for cultural media, which enables the display screen to be viewed at the best angle through a face recognition system and a variety of adjustment mechanisms. By setting an L-shaped track, a three-dimensional display is achieved, which can better reflect the 3D effect. The display screen arrangement position can be adjusted by pushing the cylinder, and the angle of the display screen can be adjusted by the adjustment mechanism, thereby providing the best viewing angle for the crowd and producing the best 3D visual experience.

[0029] like Figure 1-7 The present invention provides a digital display device for cultural media, including a display stand 1, a display screen 2 and an adjustment stand 3. The display stand 1 is provided with a transposition slide rail 4, and the transposition slide rail 4 is composed of two mutually perpendicular and connected linear slide rails 1 5 and 6. The transposition slide rail 4 is an L-shaped slide rail. The display screen 2 is used to play promotional images, and includes a structure and system for presenting naked-eye 3D images, as well as image data. The display screen 2 is provided with two, including a display screen 1 7 and a display screen 2 8, which are arranged in the transposition slide rail 4, and can be moved and adjusted on the transposition slide rail 4 to adjust to a more suitable viewing angle. The adjustment stand 3 is provided with an adjustment mechanism 9, and the display stand 1 is arranged on the adjustment mechanism 9.

[0030] Among them, two sliders are arranged in the transposition slide rail 4, including a driving slider 10 and a driven slider 11. The driving slider 10 is rotatably connected to one end of the display screen 1 7, and the other end of the display screen 1 7 is provided with a pulley 12. The driven slider 11 is rotatably connected to one end of the display screen 2 8, and the other end of the display screen 2 8 is provided with a pulley 12. The pulley 12 slides in the transposition slide rail 4. A conversion rod 13 is connected between the driving slider 10 and the driven slider 11. The conversion rod 13 and the two sliders are hinged. A pushing cylinder 14 is hinged on the driving slider 10, and an extension end is provided on the conversion rod 13 at one end on the driving slider 10. The telescopic end and the extension end of the pushing cylinder 14 are hinged.

[0031] The driving slider 10 only slides in the linear slide rail 1 5 , the driven slider 11 only slides in the linear slide rail 2 6 , and the pulley 12 can slide in the entire transposition slide rail 4 .

[0032] The push cylinder 14 is started, and then the conversion rod 13 is pushed to rotate around the driving slider 10, and the other end of the conversion rod 13 pushes the driven slider 11 to slide, and because the conversion rod 13 connects the driving slider 10 and the driven slider 11, the driven slider 11 also pulls the driving slider 10 to slide. Then the display screen 1 7 and the display screen 2 8 move in the transposition slide rail 4 at the same time, so that the display screen 1 7 and the display screen 2 8 can be moved to the linear slide rail 1 5 or the linear slide rail 2 6 at the same time, and the two are spliced ​​into a larger display screen; or the display screen 1 7 and the display screen 2 8 are arranged in the linear slide rail 1 5 and the linear slide rail 2 6 respectively, and the two form an L-shaped screen.

[0033] The adjusting mechanism 9 comprises a worm wheel 15, a worm 16, a worm wheel frame 17, a worm frame 18, a motor 19 and a motor 20. A support frame 21 is provided on the adjusting platform 3. The worm 16 is rotatably arranged on the support frame 21. The worm frame 18 is rotatably arranged on the support frame 21. An extension shaft 22 is provided at one end of the worm 16. The extension shaft 22 passes through the support frame 21. A swivel 23 is provided at one end of the worm frame 18. The swivel 23 is rotatably arranged on the support frame 21, and the extension shaft 22 passes through the swivel 23.

[0034] The worm frame 18 is provided with a collar 24, the worm wheel 15 is rotatably arranged in the collar 24, the worm wheel 15 is meshed with the worm 16, the worm wheel frame 17 is rotatably arranged on the collar 24, the worm wheel frame 17 and the worm wheel 15 are coaxial, the motor 19 is connected to the worm frame 18, the driving end of the motor 20 is connected through the rotating ring 23 and the extension shaft 22 of the worm 16, and the display stand 1 is arranged on the worm wheel frame 17.

[0035] The rotation direction of the worm gear frame 17 is different from the rotation direction of the worm frame 18 .

[0036] When the motor 19 is started, the worm frame 18 is driven to rotate, and the worm gear frame 17 is also rotated; when the motor 20 is started, the worm 16 is driven to rotate, and then the worm gear 15 is driven to rotate, and then the worm gear frame 17 is rotated. The two rotation directions are two dimensions respectively, so that the display stand 1 can be driven to adjust the angle in multiple dimensions.

[0037] The display screen 2 is provided with a face recognition system, and is control-connected with the push cylinder 14 and the adjustment mechanism 9 .

[0038] The facial recognition system identifies the orientation of the viewing crowd, and then controls the position and angle of the display screen. The display screen arrangement position can be adjusted by pushing the cylinder 14, and the angle of the display screen can be adjusted by the adjustment mechanism 9, thereby providing the best viewing angle for the crowd and producing the best 3D visual experience.

[0039] Since the width of the two display screens 2 after splicing is equivalent to a linear slide rail, when the two display screens 2 are in a perpendicular state to each other, that is, when the two display screens 2 are arranged in two linear slide rails, a large area of ​​empty space will be generated. Therefore, a folding sub-screen 25 is hingedly provided on the two display screens 2, and a folding hydraulic cylinder 26 is hingedly provided on the display screen 2, and the telescopic end of the folding hydraulic cylinder 26 is hinged to the folding sub-screen 25.

[0040] When the two display screens 2 are perpendicular to each other, the folding sub-screen 25 is unfolded by controlling the folding hydraulic cylinder 26 to fill the empty space. The four display screens 2 can completely fill the entire slide rail space, thereby expanding the visual range and improving the display effect.

[0041] A protective cover 27 is disposed outside the adjusting mechanism 9 .

[0042] When used specifically, the face recognition system is used to identify the largest number of viewers, and then the position of the display screen 2 is adjusted. The push cylinder 14 is started, and then the conversion rod 13 is pushed to rotate around the driving slider 10, and the other end of the conversion rod 13 pushes the driven slider 11 to slide, and because the conversion rod 13 connects the driving slider 10 and the driven slider 11, the driven slider 11 also pulls the driving slider 10 to slide. Then the display screen 1 7 and the display screen 2 8 move in the transposition slide rail 4 at the same time. When the display screen 1 7 and the display screen 2 8 can be in the same linear slide rail at the same time, the two are spliced ​​into a larger display screen; when the display screen 1 7 and the display screen 2 8 are arranged in the linear slide rail 1 5 and the linear slide rail 2 6, the two form an L-shaped screen. At this time, there is still a vacancy next to the screen. The folding hydraulic cylinder 26 is started to control the folding sub-screen 25 to unfold, and then the vacancy can be filled. The four display screens can completely fill the entire slide rail space, thereby expanding the visual range and improving the display effect.

[0043] In addition, the angle can be adjusted. When the motor 19 is started, the worm frame 18 is driven to rotate, and the worm gear frame 17 is also rotated accordingly; when the motor 20 is started, the worm 16 is driven to rotate, and then the worm gear 15 is driven to rotate, and then the worm gear frame 17 is rotated accordingly. The two rotation directions are two dimensions respectively, so that the display stand 1 can be driven to adjust the angle in multiple dimensions, which further improves the observation effect.
