Description

Technical Field

[0001] The invention relates to the technical field of LED display screens, in particular to a curved surface adjustment structure of an LED display screen and an LED display screen. Background Art

[0002] LED curved display is a display technology with innovative design. It is different from traditional flat display. The screen presents a certain curvature. This curved design is not only for the unique appearance, but also brings many advantages. From the perspective of visual experience, the curve can provide a wider viewing angle, reduce the visual distortion at the edge of the screen, and enable users to obtain relatively consistent clear images and color performance when watching from different angles. In terms of immersive experience, the curved screen can better surround the viewer's field of vision and enhance the immersive feeling of viewing, especially in scenes such as watching movies and playing games, making people feel as if they are in the scene. In addition, the curved design can also reduce the reflection of ambient light to a certain extent, reduce visual interference, and improve the contrast and brightness uniformity of the screen. For example, using LED curved display in home theater can allow the audience to be more fully immersed in the plot of the film; in the e-sports scene, players can more keenly capture the details in the game screen and enhance the gaming experience. In general, LED curved display brings users a better and more attractive visual enjoyment with its unique design and excellent performance.

[0003] LED display screens are usually composed of multiple LED cabinets. The general LED cabinet is surrounded by four frames, and the shape of the frames is fixed. The LED cabinet cannot adjust the angle of the LED display screen, or its adjustment structure is relatively complicated, and it is not easy to achieve the purpose;

[0004] The Chinese patent with the announcement number "CN109215518B" discloses a curved surface adjustment structure of an LED display screen and an LED display screen, which includes an LED display screen frame base, a motor, a screw, an open groove, a groove, a threaded barrel, a slide plate, a slide groove, an adjustment rod and a pulley. The above device drives the threaded barrel to move through the screw. Since the pulley extends into the arc groove and the upper and lower ends of the limit rod are slidably connected inside the arc groove, the right side of the LED display screen frame is rotated outward, the left side is rotated inward, or the right side is rotated inward and the left side is rotated outward, thereby adjusting the curved surface angle of the LED display screen body. The adjustment method is simple and easy to achieve;

[0005] During the application of the above device, although the function of angle adjustment can be realized, it still has certain defects and shortcomings in the specific application process. First, when in use, it can only perform preliminary angle adjustment. When multi-angle rotation adjustment is required, it is obviously not adaptable. In daily life, in order to protect the display screen and avoid occupying the space of the wall and the ground, in most cases, the display screen will be installed at a higher position on the wall, or even directly installed on the ceiling of the house. However, if the display screen is in a hanging state, its design that can only be adjusted left and right is obviously not convenient for adapting and adjusting according to the user's specific viewing position and angle. This performance of only being able to swing left and right is inconvenient when used when hung or installed at a higher position, so it is necessary to improve it. For example, in a conference room, if the display screen is mounted on the ceiling and can only be adjusted left and right, then participants sitting in different positions may not be able to get a good viewing experience; for example, in a home theater scene, if the display screen is installed at a higher position and can only be adjusted left and right, and the user is on the ground, he obviously needs to look up to see it, and it is not easy to observe the specific display situation when looking up. It can be seen that its overall use has certain defects, which will affect the viewing experience of family members in different positions, and it needs to be improved. Summary of the invention

[0036] The working principle of the present invention is as follows: by setting up the annular adjustment mechanism 3, the device can be operated by starting the third motor 343 during use. When the third motor 343 is running, it can drive the rotating wheel 342 to rotate inside the mounting frame 341. With the help of the rotation of the rotating wheel 342, the curved display screen 9 installed on the front side of the adjusting wheel 342 can be assisted to rotate. At this time, the curved display screen 9 can be adjusted up and down. During use, if left and right adjustment is required, the second motor 334 can be started to operate. The second motor 334 The gear 335 can be driven to rotate. Since the gear 335 and the gear ring 333 are in a meshing connection state, as the gear 335 rotates, the gear ring 333 can be driven to cause the slip ring 332 to slide on the inner side of the annular rail 32. As the slip ring 332 rotates, the fixed frame 31 can be driven to rotate. The rotation of the fixed frame 31 can make the gear 335 in a horizontal state, and the rotating wheel 342 is also in a horizontal state. At this time, the rotation direction of the rotating wheel 342 is changed, and the second motor 334 is started again to run, and the rotating wheel 342 can be driven to rotate by the second motor 334 , the display screen can be flexibly adjusted to the left and right by rotating the rotating wheel 342, so that the device can be flexibly adjusted to the left and right displacement as a whole during use, and during the adjustment process, as the display screen mounting protrusion 24 rotates, the curved display screen 9 is connected to the front of the display screen mounting protrusion 24 by rotation, and a weight block 11 is fixedly installed in the middle of its bottom, and the weight block 11 provides gravity for the curved display screen 9, so that the display screen mounting protrusion 24 can rotate in real time during the rotation process, so that the curved display screen 9 as a whole can always be perpendicular to the ground during the rotation adjustment process, which is convenient for users to watch, and the whole can not only perform longitudinal angle adjustment as needed, but also perform lateral angle adjustment as needed, which maximizes the overall use adaptability of the device. For example, in an office scene, when the user's position changes, the device can quickly and flexibly adjust the angle of the curved display screen 9 to provide the best visual experience; in a multimedia display venue, this all-round angle adjustment function can meet the viewing needs of different audiences;

[0037] By providing the mounting mechanism 2, the display screen mounting protrusion 24 can be inserted into the interior of the mounting frame 22 during use of the device. At this time, since the display screen mounting protrusion 24 and the chassis 10 of the curved display screen 9 are rotatably connected, the curved display screen 9 will rotate under the influence of gravity during the adjustment process of the annular adjustment mechanism 3, so that the curved display screen 9 is always in a vertical state, and can be kept in a stable vertical state during the process of angle adjustment. In addition, during the installation process, when the display screen mounting protrusion 24 is inserted into the interior of the mounting frame 22, the display screen mounting protrusion 24 will abut against the limiting protrusion 2. 35, at this time, the guiding effect of the inclined surface can cause the limiting protrusion 235 to resist the limiting spring 233 to shrink, thereby reserving space for the display screen mounting protrusion 24. When the display screen mounting protrusion 24 is completely inserted into the interior of the mounting frame 22, the limiting spring 233 is reset, which can drive the limiting arm 234 to move inward, and the limiting arm 234 further drives the limiting protrusion 235 to pass through the square groove 237 and be inserted into the interior of the card slot 232. Through the mutual limitation of the card slot 232 and the limiting protrusion 235, the display screen mounting protrusion 24 can be stably installed in the interior of the mounting frame 22. If the display screen mounting protrusion 24 needs to be removed, When the display screen 9 is in the state of being disassembled and installed, the adjusting push plate 236 only needs to be pushed outward, and the outward movement of the adjusting push plate 236 can push the limiting arm 234 outward, and the outward movement of the limiting arm 234 can drive the limiting protrusion 235 to move out from the inner side of the card slot 232, and the card slot 232 and the limiting protrusion 235 are separated from each other, so that the display screen mounting protrusion 24 can be quickly removed from the inner side of the mounting frame 22, which makes the device as a whole able to quickly disassemble and install the curved display screen 9, and during use, the chassis 10 of the curved display screen 9 is provided with a heat dissipation groove and a heat dissipation window 12, which can have a good heat dissipation performance, and the setting of the dustproof net 13 can have a good dustproof performance, which can provide The convenience of the overall use of the device is improved, and the use of the device is convenient. For example, when the curved display screen 9 needs to be maintained or replaced, this quick disassembly and assembly design can save time and labor costs; during long-term use, good heat dissipation and dustproof performance can ensure the stable operation and service life of the curved display screen 9. At the same time, during use, the first motor 63 can be started to drive the screw rod 61 inside the vertical rail 4 to rotate. The rotation of the screw rod 61 can drive the slider 62 to drive the fixing frame 31 to move up and down, which can flexibly adjust the position of the curved display screen 9, can improve the overall adjustment and adaptation performance of the device, and facilitate flexible adjustment of the use of the device.
