Technical Field
[0001] This utility model relates to the field of liquid crystal displays, and in particular to a modular liquid crystal display with a replaceable outer frame. Background Technology
[0002] An LCD screen is a device that displays images by controlling the arrangement of liquid crystal molecules to modulate light. It consists of an LCD panel, a backlight module, a driving circuit, and a housing, and is widely used in various electronic devices. An LCD screen with a modular, replaceable frame design can separate the frame from the main body and achieve standardized disassembly and assembly. This not only meets the needs of personalized appearance and function in different scenarios, but also reduces the replacement cost when the frame is damaged or the style changes. At the same time, it improves installation and maintenance efficiency, reduces resource waste, and enhances product flexibility and environmental protection while better responding to diverse usage scenarios and user needs.
[0003] Existing modular LCD screens with replaceable frames operate on the same core display principle as traditional LCDs. They achieve image display by controlling the arrangement of liquid crystal molecules through a driving circuit to modulate backlight. At the same time, standardized mechanical connection structures allow for precise and detachable connection between the frame and the display body. The frame can also be expanded in function by reserving interfaces or structures to work in tandem with the body. This allows for quick frame replacement and scene adaptation without changing the core display function.
[0004] However, current modular LCD displays with replaceable frames still have a significant shortcoming in actual use. When the fixed frame is damaged due to bumps, aging, or other reasons and needs to be replaced, the disassembly process often requires complicated operations. Although some products claim to offer quick replacement, in reality, disassembly requires the use of special tools to unscrew hidden screws or forcefully pull clips, and may even require disconnecting the back connecting harness first. This not only requires users to be proficient in operating the equipment, but also prolongs the replacement time due to the cumbersome steps. Ordinary users often need more than 15 minutes to complete the process. If the operation is incorrect, it may also damage the main body of the display screen. This complicated disassembly process directly weakens the efficiency that modular design should have and makes it difficult to meet the core needs of rapid maintenance in commercial scenarios and convenient operation for home users.

[0037] 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.
[0038] Reference Figures 1-3 The present invention provides an embodiment of a modular, replaceable frame LCD display, comprising a housing 1, a connecting strip 2 fixedly connected to one side of the housing 1 for connecting a fixed frame 6, multiple fixing grooves 3 on both the outer and inner walls of the connecting strip 2 for accommodating the fixing strip 10, a display component inside the housing 1 for displaying images, a fixed frame 6 slidably connected to the outer wall of the connecting strip 2 for protecting the LCD screen 5, a fastening groove 7 inside the fixed frame 6 for accommodating the connecting strip 2, a connecting groove 8 inside the fixed frame 6 for fastening the LCD screen 5, and multiple fixing components inside the fixed frame 6 for fixing the fixed frame 6 to the housing 1;
[0039] Each fixing component includes an elastic plate 9 and a fixing strip 10. One side of the elastic plate 9 is fixedly connected to the inside of the fixing frame 6 to provide elastic force to the fixing strip 10. One side of the fixing strip 10 is fixedly connected to one side of the elastic plate 9 to fix the fixing frame 6 to the housing 1. The outer wall of the fixing strip 10 is slidably connected to the inside of the fixing groove 3. The display component includes a display device 4 and a liquid crystal screen 5. One side of the display device 4 is fixedly connected to the inside of the housing 1 to convert electrical signals into light signals and guide them to the liquid crystal screen 5. One side of the liquid crystal screen 5 is fixedly connected to one side of the display device 4 to display images.
[0040] Specifically, when it is necessary to replace the fixing frame 6, first, firmly grasp both sides of the fixing frame 6 with your hands and pull it outward smoothly with a little force. At this time, the fixing strip 10 on the inner side of the fixing frame 6 will be squeezed by the outer wall of the connecting strip 2. Under the action of the squeezing force, it will retract into the groove along the guide track of the fastening groove 7, so that the locking state between the fixing frame 6 and the connecting strip 2 will be released. Then, continue to move the fixing frame 6 outward at a constant speed, and it can be easily removed from the connecting strip 2. The entire disassembly process does not require any tools. Next, take out the new fixing frame 6, align it with the fastening position on the connecting strip 2 and push it inward. When the connecting strip 2 is completely inserted into the fixing frame 6, the fixing strip 10 will automatically pop out and be inserted into the fixing groove 3 under the elastic action of the elastic plate 9. At this point, the new fixing frame 6 is firmly fastened to the connecting strip 2 to complete the replacement.
[0041] Reference Figures 4-6 A connecting plate 11 is slidably connected to one side of the outer casing 1 for connecting the outer casing 1 and the fixing plate 14. Multiple fixing bolts 12 are threaded inside the connecting plate 11 for fixing the connecting plate 11 and the outer casing 1. Multiple limiting strips 13 are fixedly connected to one side of the connecting plate 11 to limit the movement range of the outer casing 1. The limiting strips 13 are arranged in a symmetrical array on one side of the connecting plate 11. A fixing plate 14 is provided on one side of the connecting plate 11 for connecting the equipment to the wall. Multiple connecting holes 15 are opened inside the fixing plate 14 for accommodating screws. Multiple fixing blocks 16 are fixedly connected to one side of the fixing plate 14 for connecting the fixing plate 14 and the connecting plate 11. Each fixing block 16 has a sliding groove 17 inside for accommodating the limiting strips. Each of the fixed blocks 16 has multiple docking holes 18 at both ends to accommodate docking strips 20. Each of the fixed blocks 16 has a slidable limit plate 19 at both ends to block the sliding groove 17. Each limit plate 19 has multiple docking strips 20 fixedly connected to one side to connect the limit plate 19 and the fixed block 16. Each limit plate 19 has a limit block 21 fixedly connected to one side to limit the movement range of the limit strips 13. The docking holes 18 are arranged in a symmetrical array at one end of the fixed block 16, and the limit plates 19 are arranged in a symmetrical array at both ends of the fixed block 16. The outer wall of each docking strip 20 is slidably connected to the inside of the docking hole 18, and the outer wall of each limit block 21 is slidably connected to the inside of the sliding groove 17.
[0042] Specifically, when installing the equipment, first, place the fixing plate 14 stably on the pre-selected fixing surface. Then, take out the matching screws, align them with the connecting holes 15 at the four corners of the fixing plate 14, and use a screwdriver to screw the screws in at a uniform speed until the screw heads are tightly pressed against the surface of the fixing plate 14. At this point, the fixing plate 14 is firmly fixed to the surface. Next, hold the main body of the equipment with both hands, align the protruding limiting strip 13 with the sliding groove 17 on the fixing plate 14, insert the limiting strip 13 into the entrance of the sliding groove 17, and then slowly insert it along the direction of the groove. Slowly push the device so that the limiting strip 13 slides smoothly into the sliding groove 17 until the back of the device is completely in contact with the fixing plate 14. Then, take out the limiting plate 19 and align the mating strip 20 and the limiting block 21 on one side with the mating holes 18 and the sliding groove 17 at both ends of the fixing block 16, respectively. Press the limiting plate 19 inward with a little force, insert the mating strip 20 into the mating hole 18, and the limiting block 21 into the end of the sliding groove 17, so that the limiting plate 19 is fastened to the fixing block 16, and the device is also securely limited. The entire installation process is then successfully completed.
[0043] Working principle: When using the modular replaceable frame LCD screen, first place the fixing plate 14 on the plane to be fixed, and fix the screws in the connecting hole 15 to fix the fixing plate 14. Then hold the device and align the limiting strip 13 on its back with the sliding groove 17 and slide it into the sliding groove 17. After that, take out the limiting plate 19 and align the docking strip 20 and the limiting block 21 on one side with the docking hole 18 and the sliding groove 17 and snap them together, so that the device can be installed on the plane to be used. When the fixing frame 6 needs to be replaced, first hold the fixing frame 6 and pull it outward so that the fixing strip 10 is squeezed by the outer wall of the connecting strip 2 and retracted into the snap-fit groove 7 to unlock the fixing frame 6. Then continue to move the fixing frame 6 outward to remove it. Then take out the new fixing frame 6 and snap it onto the connecting strip 2.
