Description

Technical Field

[0001] This utility model relates to the field of media playback technology, and more specifically, to an adaptive splicing screen media playback device. Background Technology

[0002] LCD video walls can be used as individual displays or spliced ​​together to form ultra-large screens. The display area can be flexibly adjusted according to different needs. Existing media playback devices based on video walls usually consist of multiple displays and mounting brackets. The multiple displays are fixedly mounted on the brackets and spliced ​​together to form a rectangular video wall of fixed size. The installation position of the displays on the brackets is fixed and cannot be adjusted.

[0003] When the display area of ​​a video wall needs to be expanded to meet media playback requirements (e.g., airport flight information systems need to display more flight information in the original area due to the opening of new routes; shopping mall atriums need to enhance the visual impact of advertising videos to support large-scale promotional activities), removing the display screen from the bracket and replacing it with a larger screen in the original position may result in installation difficulties due to positional interference between the screens. In this case, the installation position of the screen on the bracket needs to be adjusted, but this is often difficult to achieve because the bracket size is fixed, easily leading to situations where the screen cannot be installed. Conversely, when the display area of ​​a video wall needs to be reduced (e.g., shopping malls adjust large promotional areas into multiple independent brand display areas, requiring smaller video wall units; corporate meeting rooms do not require full-screen display for daily use, only partial screens to display meeting materials), replacing the screen in the original position with a smaller screen will create gaps between adjacent screens, making it impossible to form a complete video wall and causing difficulties for media playback. Utility Model Content

[0004] The purpose of this invention is to provide an adaptive video wall media playback device to solve the problems mentioned in the background section.

[0005] The display screen's mounting position on the bracket is fixed and cannot be adjusted. When it is necessary to expand or shrink the display area of ​​the splicing screen according to media playback requirements, it cannot be achieved by replacing the display screen on the bracket.

[0006] To address the above problems, the present invention aims to provide an adaptive splicing screen media playback device, including a bracket. A fixed box is fixedly installed on the top of one side of the bracket. Movable boxes are installed above and below the fixed box. The openings of the movable boxes and the fixed box face the same side. A height adjustment mechanism is provided on the fixed box, which is used to move the two movable boxes synchronously away from or closer to the fixed box. Two connecting blocks are symmetrically arranged on one side of the movable box, and a distance adjustment mechanism is provided on the movable box, which is used to move the two connecting blocks synchronously in opposite directions horizontally. A display screen is fixedly installed on the side of the connecting blocks away from the movable box. After the height adjustment mechanism and the distance adjustment mechanism adjust the positions of the four connecting blocks, the four display screens are spliced ​​together to form a rectangular splicing screen.

[0007] As a further improvement to this technical solution, the height adjustment mechanism includes a first lead screw that is horizontally rotatably disposed inside the fixed box. The first lead screw is threaded with a first slide table near both ends, and the threaded connection directions of the two first slide tables and the first lead screw are opposite. A first motor is fixedly installed on one side of the fixed box, and one end of the first lead screw rotatably passes through one side of the fixed box and is coaxially fixedly connected to the output shaft of the first motor through a coupling.

[0008] As a further improvement to this technical solution, the top and bottom of the first slide table near the opening of the fixed box are fixedly provided with a first extension frame. The other end of the first extension frame extends to the outside of the fixed box through the opening and is hinged to a connecting rod. The connecting rod is inclined and the other end of the connecting rod is hinged to the side wall of the corresponding movable box near the fixed box.

[0009] As a further improvement to this technical solution, the adjusting mechanism includes a second lead screw that is horizontally rotatably disposed inside the movable box. The second lead screw is threaded with a second slide table near both ends, and the threaded connection directions of the two second slide tables and the second lead screw are opposite. A second motor is fixedly installed on one side of the movable box, and one end of the second lead screw rotatably passes through one side of the movable box and is coaxially and fixedly connected to the output shaft of the second motor through a coupling.

[0010] As a further improvement to this technical solution, the top and bottom of the second slide table near the opening of the moving box are both fixedly provided with second extension frames. The other ends of the two second extension frames extend to the outside of the moving box through the opening and are fixedly provided with the same end plate. The connecting block is fixedly provided on the corresponding end plate.

[0011] As a further improvement to this technical solution, guide rods are vertically fixedly installed on the upper and lower side walls of the fixed box near both ends, and sleeves are vertically fixedly installed on the side of the movable box near the fixed box corresponding to the guide rods, with the sleeves slidably fitted on the outside of the corresponding guide rods.

[0012] As a further improvement to this technical solution, two slide rods are horizontally fixed inside both the fixed box and the movable box. The first slide is slidably sleeved on the slide rod inside the fixed box, and the second slide is slidably sleeved on the slide rod inside the movable box.

[0013] As a further improvement to this technical solution, a dust cover is fixedly installed on the side of the fixed box and the movable box away from the bracket. The dust cover blocks the opening of the fixed box or the movable box, and a gap is left between the dust cover and the fixed box or the movable box. The first extension frame and the second extension frame are slidably installed in the corresponding gap.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This adaptive splicing screen media playback device first adjusts the distance between two connecting blocks on the same moving box by adjusting the distance mechanism, so that the two screens at the same height can contact each other. Then, the distance between the two moving boxes is adjusted by adjusting the height mechanism, so that the upper and lower sets of screens can contact each other. Finally, all four screens can contact each other. Thus, four screens of any size and the same specification can be spliced ​​together to form a splicing screen of a predetermined size, which can adapt to different media playback scenarios.

[0016] 2. In this adaptive splicing screen media playback device, the first lead screw and the second lead screw, the first slide and the second slide, the first extension frame and the second extension frame, the first motor and the second motor are all the same components. If any of these components is damaged, the same component can be used for universal replacement, thereby significantly reducing the maintenance difficulty and cost of the device.

[0031] 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.

[0032] Example 1

[0033] Please see Figures 1-3 As shown, the purpose of this embodiment is to provide an adaptive splicing screen media playback device, including a bracket 1. The lower side wall of the bracket 1 contacts the ground. A fixed box 3 is fixedly installed on the top of one side of the bracket 1. Movable boxes 4 are installed above and below the fixed box 3. The openings of the movable boxes 4 and the fixed box 3 face the same side. A height adjustment mechanism 5 is provided on the fixed box 3. The height adjustment mechanism 5 is used to drive the two movable boxes 4 to move away from or closer to the fixed box 3 synchronously, thereby adjusting the distance between the two movable boxes 4. Two connecting blocks 6 are symmetrically arranged on one side of the movable box 4, and a distance adjustment mechanism 7 is provided on the movable box 4. The distance adjustment mechanism 7 is used to drive the two connecting blocks 6 to move horizontally in opposite directions synchronously, thereby adjusting the distance between the two connecting blocks 6. A display screen 2 is fixedly installed on the side of the connecting block 6 away from the movable box 4. By adjusting the distance between the two movable boxes 4 through the height adjustment mechanism 5, and by adjusting the distance between the corresponding two connecting blocks 6 through the distance adjustment mechanism 7 on each movable box 4, the position of the four connecting blocks 6 can be adjusted. The connecting blocks 6 drive the corresponding display screen 2 to move synchronously, so that the four display screens 2 are spliced ​​together to form a rectangular splicing screen for media playback.

[0034] The display screen 2 and the connecting block 6 are fixed together by bolts. The display screen 2 is detachably installed on the connecting block 6 so that different sizes of display screen 2 can be replaced. After four display screens 2 of the same size are installed on four connecting blocks 6, the distance between two connecting blocks 6 on the same moving box 4 is first adjusted by the distance adjustment mechanism 7 so that the two display screens 2 at that height can contact each other. Then, the distance between the two moving boxes 4 is adjusted by the height adjustment mechanism 5 so that the upper and lower sets of display screens 2 can contact each other. Finally, the four display screens 2 can be connected to each other. Thus, four display screens 2 of any size and the same specification can be spliced ​​together to form a splicing screen of a predetermined size to adapt to different usage scenarios.

[0035] The structure of the adjusting mechanism 7 is described in detail below, with reference to... Figure 4 The adjusting mechanism 7 includes a second lead screw 71 horizontally rotatably disposed inside the movable box 4. A second slide 72 is threadedly connected to both ends of the second lead screw 71, and the threaded connection directions of the two second slides 72 and the second lead screw 71 are opposite. Two slide rods 9 are horizontally fixedly disposed inside the movable box 4. The second slide 72 is slidably sleeved on the slide rods 9, and the axis of the slide rods 9 is parallel to the axis of the second lead screw 71, allowing the second slide 72 to move only along the axis of the slide rods 9. A second motor 75 is fixedly installed on one side of the movable box 4. One end of the second lead screw 71 rotatably passes through one side of the movable box 4 and is coaxially fixedly connected to the output shaft of the second motor 75 via a coupling. Second extension brackets 73 are fixedly disposed at the top and bottom of the second slide 72 near the opening of the movable box 4. The other ends of the two second extension brackets 73 extend through the opening to the outside of the movable box 4 and are fixedly disposed on the same end plate 74. A connecting block 6 is fixedly disposed on the corresponding end plate 74.

[0036] When the output shaft of the second motor 75 drives the second lead screw 71 to rotate, the slide bar 9 constrains the second slide table 72 so that it cannot rotate with the second lead screw 71. Since the thread directions of the two second slide tables 72 are opposite, they move synchronously in opposite directions along the axis of the slide bar 9. The moving second slide table 72 drives the corresponding connecting block 6 to move through the second extension frame 73 and the end plate 74, thereby adjusting the distance between the two display screens 2 located at the same height until the sides of the two display screens 2 contact each other.

[0037] The following details the structure of the height adjustment mechanism 5, referring to... Figure 4 and Figure 5The height adjustment mechanism 5 includes a first lead screw 51 horizontally rotatably disposed inside the fixed box 3. Two first slides 52 are threadedly connected to the first lead screw 51 near both ends, with the threaded connection directions of the two slides 52 opposite to those of the first lead screw 51. Two slide rods 9 are horizontally fixed inside the fixed box 3, with the axis of the slide rods 9 parallel to the axis of the first lead screw 51. The first slides 52 are slidably mounted on the slide rods 9, allowing the first slides 52 to move only along the axis of the slide rods 9. A first motor is fixedly installed on one side of the fixed box 3. 55. One end of the first lead screw 51 rotates through one side of the fixed box 3 and is coaxially and fixedly connected to the output shaft of the first motor 55 through a coupling. The top and bottom of the first slide table 52 near the opening of the fixed box 3 are fixedly provided with a first extension frame 53. The other end of the first extension frame 53 extends through the opening to the outside of the fixed box 3 and is hinged to a connecting rod 54. The connecting rod 54 is inclined and the other end of the connecting rod 54 is hinged to the side wall of the corresponding movable box 4 near the fixed box 3. The two connecting rods 54 at the same height form a figure-eight structure.

[0038] When the output shaft of the first motor 55 drives the first lead screw 51 to rotate, the slide bar 9 constrains the first slide table 52 so that it cannot rotate with the first lead screw 51. Since the thread directions of the two first slide tables 52 are opposite, the two first slide tables 52 move synchronously in opposite directions along the axis of the slide bar 9. The moving first slide table 52 drives the lower end of the corresponding connecting rod 54 (near the fixed box 3) to move horizontally through the first extension frame 53. Since the connecting rod 54 is inclined and its upper end (near the moving box 4) is hinged to the side wall of the moving box 4, this hinge structure makes the connecting rod 54 only change angle. Therefore, when the lower end of the connecting rod 54 moves horizontally, its length remains unchanged, and its upper end will inevitably produce a vertical displacement, thereby driving the moving box 4 to move vertically. The two moving boxes 4 move in opposite directions, thereby realizing the adjustment of the distance between the two moving boxes 4. By adjusting the distance between the two moving boxes 4, the moving box 4 drives the display screen 2 on it to move, and finally the sides of the two adjacent display screens 2 come into contact with each other, so that the four display screens 2 can be spliced ​​together to form a splicing screen.

[0039] Simultaneously refer to Figure 6 Guide rods 31 are vertically fixedly installed on the upper and lower side walls of the fixed box 3 near both ends. Sleeves 41 are vertically fixedly installed on the side of the movable box 4 near the fixed box 3, corresponding to the guide rods 31. The sleeves 41 are slidably sleeved on the outside of the corresponding guide rods 31. When the movable box 4 moves vertically, the sleeves 41 slide along the guide rods 31 with the movable box 4. During this process, the sleeves 41 and the guide rods 31 cooperate to constrain the movable box 4 to only move vertically, thereby improving the stability of the movable box 4 during the movement process.

[0040] Dust covers 8 are fixedly installed on the side of the fixed box 3 and the movable box 4 away from the bracket 1. The dust covers 8 block the opening of the fixed box 3 or the movable box 4 to prevent external dust from adhering to the first lead screw 51 and the second lead screw 71, ensuring the reliability of the threaded transmission. A gap is left between the dust cover 8 and the fixed box 3 or the movable box 4. The first extension frame 53 and the second extension frame 73 are slidably installed in the corresponding gap to ensure the free movement of the first extension frame 53 and the second extension frame 73. The above mechanisms work together to achieve precise movement of the positions of the four display screens 2, so that they can be spliced ​​together to form a large splicing screen.

[0041] The first motor 55 and the second motor 75 in this device are both servo motors with adjustable output shaft rotation direction. By changing the output shaft rotation direction of the first motor 55, the two moving boxes 4 can be controlled to move away from or towards the fixed box 3 synchronously. By changing the output shaft rotation direction of the second motor 75, the two displays 2 at the same height can be controlled to move closer to or away from each other.

[0042] The first lead screw 51 and the second lead screw 71, the first slide table 52 and the second slide table 72, the first extension frame 53 and the second extension frame 73, the first motor 55 and the second motor 75 in this device are all the same components. If any of these components is damaged, they can be replaced with the same components, thereby reducing the maintenance pressure of this device.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
