[0002] With the development of information technology, LCD screens have been widely used in various fields such as commercial display, conference systems, home entertainment and public information dissemination. In order to save space, optimize the viewing experience and achieve an aesthetically pleasing interior layout, hanging LCD screens on the ceiling has become a mainstream installation method.

[0003] Most existing suspended LCD screens are rigid fixed structures or only have simple tilt angle adjustment functions. Once installed, the height of the screen is fixed. For operators who need to maintain, replace cables or clean the screen, the screen is fixed at a high position for a long time, which is extremely inconvenient and poses a safety hazard. Moreover, the fixed hanging height cannot adapt to different indoor heights or users of different heights, resulting in a poor viewing experience when looking up. Therefore, a suspended LCD screen is proposed. Utility Model Content

[0021] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] A type of suspended LCD screen, such as Figures 1-4 As shown, the system includes an LCD screen 1. The back of the LCD screen 1 is fixed to a mounting base 4 using bolts or other fasteners. A suspension assembly is mounted on the mounting base 4. The upper end of the suspension assembly is fixed to the wall. The suspension assembly includes a mounting frame 2. The top of the mounting frame 2 is fixed to the ceiling or a load-bearing component of the roof using expansion bolts. Two sets of upper sliding seats 8 are slidably connected to the bottom of the mounting frame 2. Connecting arms 9 are rotatably mounted on the lower ends of the two sets of upper sliding seats 8. The two sets of connecting arms 9 are staggered, and the staggered position is rotatably mounted using a pin (the two sets of connecting arms 9 are like scissors; when one end opens, the other end also opens and closes, and the linear distance between the two ends changes at the same time). Lower sliding seats 10 are rotatably mounted on the lower ends of the two sets of connecting arms 9. A support rod 11 is slidably mounted between the two sets of lower sliding seats 10. The friction between the lower sliding seats 10 and the support rod 11 is small, and the lower sliding seats 10 can slide smoothly on the support rod 11. The support rod 11 can also rotate relative to the lower sliding seats 10. The mounting base 4 is fixedly connected to the middle of the support rod 11.

[0023] When the mechanical drive moves the two sets of upper sliding seats 8 in opposite directions, the angle between the upper sliding seats 8 and the connecting arms 9 changes, and the opening degree of the upper ends of the two sets of connecting arms 9 changes, causing the opening degree of the lower ends of the two sets of connecting arms 9 to change, which in turn causes the distance between the two sets of lower sliding seats 10 to change. The lower sliding seats 10 slide on the support rod 11, and the distance between the support rod 11 and the mounting frame 2 changes, thus adjusting the height of the LCD screen 1. The staff can easily lower the high-suspended display screen to a suitable height, which is convenient for operations such as screen cleaning, cable replacement or interface plugging and unplugging, reducing safety hazards. It can also be adjusted according to different usage scenarios and viewers.

[0024] A double-ended screw 7 is rotatably installed inside the mounting frame 2. The two ends of the double-ended screw 7 are respectively machined with two threaded sections with opposite directions of rotation. Two sets of upper sliding seats 8 are sleeved on the double-ended screw 7, and the two sets of upper sliding seats 8 are respectively connected and engaged with the threaded sections at both ends. The two sets of upper sliding seats 8 move in opposite directions along the axis of the double-ended screw 7.

[0025] The bottom of the mounting frame 2 is provided with a sliding groove 13. The lower ends of the two sets of upper sliding seats 8 are slidably connected in the sliding groove 13. Both ends of the support rod 11 are threaded with end caps 12. The end caps 12 seal both ends of the support rod 11 to prevent the lower sliding block from detaching. The support rod 11 can be pulled out by removing the end caps 12, which is convenient for disassembly and assembly.

[0026] A servo motor 16 (model 110ST-M05030) is fixed to the inner wall of the mounting frame 2. A drive gear 15 is fixed to the output end of the servo motor 16. A driven gear 14 is fixed to the middle of the double-ended screw 7. The drive gear 15 and the driven gear 14 mesh and transmit power.

[0027] The output end of the servo motor 16 drives the drive gear 15 to rotate. The drive gear 15 meshes with and drives the driven gear 14, which in turn drives the double-ended screw 7 to rotate. The two sets of upper sliding blocks are symmetrical about the center of the double-ended screw 7, and the upper sliding blocks can only slide along the axis of the double-ended screw 7. The rotation of the double-ended screw 7 will drive the two sets of upper sliding blocks to move in opposite directions, thereby driving the two sets of connecting arms 9 to open and close.

[0028] The back of the LCD screen 1 has a connection port 3, and a wire clamp 6 is fixed on the mounting base 4. The wire clamp 6 is located above the connection port 3.

[0029] Connector 3 can connect to signal cables or power cables. Signal cables and power cables can be clipped onto connector 3. Cable clip 6 organizes signal cables and power cables.

[0030] The fixed base 4 has a positioning hole 5, and the side wall of the support rod 11 has a positioning hole 17. The positioning hole 5 and the positioning hole 17 are mated together, and the fixed base 4 and the support rod 11 are fixed together by bolts.

[0031] After the support rod 11 is inserted, the positioning hole 5 and the positioning hole 17 are aligned. Bolts are then inserted into the positioning hole 5 and the positioning hole 17 to position and fix the fixed seat 4 and the support rod 11.

[0032] The working principle of the suspended LCD screen provided by this utility model is as follows:

[0033] When the height needs to be changed, the servo motor 16 is activated, driving the drive gear 15 and the driven gear 14, causing the double-headed screw 7 to rotate in a specific direction. Since the threads at both ends of the double-headed screw 7 turn in opposite directions, the two upper sliding blocks 8 fitted on it will move simultaneously along the screw axis toward the middle (or end). The upper sliding blocks will push or pull the upper ends of the two connecting arms 9 that are hinged to them to retract or open. Under the combined action of gravity and the linkage mechanism, the two interlocking connecting arms 9 will unfold around the hinge point in the middle, that is, their lower ends will open or retract, thereby pushing the two lower sliding blocks 10 to slide toward both ends or toward the middle on the support rod 11, so that the height of the entire X-shaped linkage structure changes, driving the LCD screen to change its height smoothly. The staff can easily lower the suspended screen to a suitable height, which is convenient for operations such as screen cleaning, cable replacement or interface plugging and unplugging, reducing safety hazards, and can be adjusted according to different usage scenarios and viewing groups.

[0034] 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 illustrative of the principles of this 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.
