Description

Technical Field

[0001] This utility model relates to the field of liquid crystal display technology, specifically to a frameless liquid crystal display screen. Background Technology

[0002] Frameless LCD displays represent a design trend in LCD technology, aiming to minimize the width of the bezels around the display to achieve a larger display area and a more immersive visual experience.

[0003] First, a fixed screen cannot meet the needs of users, but a pop-up screen may wobble when adjusted if it lacks stability, which will reduce the user experience and may also pose a risk to the device hardware.

[0004] Secondly, the display screen may shake or shift during the lifting and lowering process, which not only affects the adjustment efficiency but may also damage the screen hardware. Without stable assistance, the screen may tip over or fall due to an unstable center of gravity during lifting and lowering.

[0005] Finally, the inability to quickly disassemble the heat dissipation device may prevent users from maintaining the heat dissipation components in a timely manner, causing the display screen to remain at a high temperature for a long time, affecting its performance and lifespan.

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.

[0029] Example 1:

[0030] Please see Figures 1-5 A frameless liquid crystal display screen includes a main body 1, a lifting mechanism, and a heat dissipation assembly. The lifting mechanism includes a base 2, a drive shaft 3, a mating screw 4, a sliding frame 5, a support rod 6, and auxiliary components. The main body 1 is mounted on the base 2 and slidably connected to the base 2. The drive shaft 3 is mounted inside the base 2 and rotatably connected to the base 2. The mating screw 4 is mounted inside the base 2 and is threadedly connected to the drive shaft 3 and the sliding frame 5. The sliding frame 5 is mounted inside the base 2 and slidably connected to the main body 1. One end of the support rod 6 is mounted on the sliding frame 5 and rotatably connected to the sliding frame 5. The auxiliary components include a first roller 7, a second roller 8, and a connecting rod 9. The first roller 7 is mounted on one end of the support rod 6 and is matingly connected to the main body 1. The second roller 8 is mounted inside the base 2 and rotatably connected to the base 2 and slidably connected to the sliding frame 5. The connecting rod 9 is mounted at the bottom of the main body 1 and is threadedly connected to the main body 1 and slidably connected to the base 2.

[0031] In this embodiment, the lifting mechanism includes a base 2, a drive shaft 3, a mating screw 4, a sliding frame 5, a support rod 6, and auxiliary components. In use, the actuating block 21 on the drive shaft 3 is rotated, causing the drive shaft 3 to rotate inside the base 2. This causes the driving gear 22 to mesh with the driven gear 23 on the mating screw 4. Under the drive of the driven gear 23, the mating screw 4 rotates and engages with the sliding frame 5 threadedly. The sliding frame 5 slides inside the base 2 while being threadedly engaged. The limiting block 26 on the sliding frame 5 slides in the limiting groove 24, and the second roller 8 slides in the second sliding groove 25 in the sliding frame 5. The change in the position of the sliding frame 5 causes the position of the support rod 6 to change as well. At the same time, one end of the support rod 6 slides in the fixing groove 19 at different positions on the fixing frame 18, and the first roller 7 slides in the first sliding groove 20, so that the main body 1 can be firmly supported on the base 2, thereby ensuring the stability of the main body 1 installation.

[0032] In this embodiment, the auxiliary components include a first roller 7, a second roller 8, and a connecting rod 9. In use, the first roller 7 allows the support rod 6 to be installed into the fixed frame 18 more quickly, while the second roller 8 ensures the smooth operation of the sliding frame 5. The connecting rod 9 assists in the smoothness of the main body 1 during lifting and lowering. In use, the connecting rod 9 is installed onto the extension rod 14 at the bottom of the main body 1. At this time, the threaded rod 17 enters the threaded hole 16 and engages with the threaded hole 16, thereby fixing the connecting rod 9 and the extension rod 14. When the main body 1 lifts and lowers, the second spring 15, which is fixed to the extension rod 14 at one end, holds a tension force on the main body 1. The second spring 15 is essentially a tension spring, and its purpose is to cooperate with the support rod 6 to make the main body 1 more stable.

[0033] In this embodiment, the heat dissipation assembly includes a first spring 10, a cooling fan 11, a locking block 12, and a mounting frame 13. In use, the mounting frame 13 is fixed to the main body 1, and the cooling fan 11 is installed into the mounting frame 13. When installing the cooling fan 11, the locking block 12 needs to be pulled so that the locking block 12 can squeeze the first spring 10, allowing the locking block 12 to enter the cooling fan 11. After the cooling fan 11 is installed into the mounting frame 13, releasing the first spring 10 that was compressed by the locking block 12 pushes the locking block 12 into the locking hole 27 of the mounting frame 13, so that the cooling fan 11 is installed on the mounting frame 13, making it easier to disassemble and replace the fan.

[0034] Example 2:

[0035] In summary, during use, the first step is to install the heat dissipation component onto the main body 1. First, fix the mounting frame 13 onto the main body 1, and then install the cooling fan 11 into the mounting frame 13. When installing the cooling fan 11, pull the locking block 12 so that it compresses the first spring 10, allowing the locking block 12 to enter the cooling fan 11. After the cooling fan 11 is installed into the mounting frame 13, releasing the first spring 10 will push the locking block 12 into the locking hole 27 of the mounting frame 13, allowing the cooling fan 11 to... Installed on the mounting frame 13, making fan disassembly and replacement easier. The height of the main body 1 on the base 2 can then be adjusted. At this point, rotating the actuating block 21 on the drive shaft 3 causes the drive shaft 3 to rotate inside the base 2, thereby causing the driving gear 22 to mesh with the driven gear 23 on the mating screw 4. Driven by the driven gear 23, the mating screw 4 rotates and engages with the sliding frame 5 threadedly. While threadedly engaged, the sliding frame 5 slides inside the base 2, and the limiting block 26 on the sliding frame 5 slides in the limiting groove 24. The second roller... The wheel 8 slides in the second groove 25 of the sliding frame 5. The change of position of the sliding frame 5 causes the position of the support rod 6 to change as well. At the same time, one end of the support rod 6 slides in the fixing groove 19 at different positions of the fixing frame 18, and the first roller 7 slides in the first groove 20, so that the main body 1 can be firmly supported on the base 2, thereby ensuring the stability of the installation of the main body 1. During the lifting and lowering of the main body 1, the function of the first roller 7 is to allow the support rod 6 to be installed into the fixing frame 18 more quickly, while the second roller 8 supports the sliding frame 5. The main body 1 maintains stable operation, while the connecting rod 9 assists in the stability of the main body 1 during the lifting and lowering process. In use, the connecting rod 9 is installed on the extension rod 14 at the bottom of the main body 1. At this time, the threaded rod 17 enters the threaded hole 16 and engages with the threaded hole 16, thereby fixing the connecting rod 9 and the extension rod 14. When the main body 1 is raised and lowered, the second spring 15, which is fixed on the extension rod 14 at one end, holds a pulling force on the main body 1. The second spring 15 is essentially a tension spring, and its purpose is to cooperate with the support rod 6 to make the main body 1 more stable.

[0036] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred.
