[0002] With the rapid development of economic level and technology, LCD TVs have quickly entered thousands of households. LCD TVs are more intelligent than traditional TVs. They can connect to the Internet and watch the programs they need. At the same time, LCD TVs are thinner, with clearer picture quality, more beautiful, and save space. LCD TVs are usually installed on the wall using a bracket, while conventional LCD TV brackets are fixed to the LCD TV.

[0003] For example, a magnetic wall-mounted device for LCD TVs (Announcement No.: CN109488848A) includes a supporting structure and a hanging structure. The supporting structure and the hanging structure of the present invention are connected by magnetic attraction. After the supporting structure and the hanging structure are connected by attraction, the attraction position can be changed by moving the hanging structure to change the hanging position of the LCD TV. When replacing the TV, there is no need to replace the supporting structure. The supporting structure can be applied to TVs of various sizes. Compared with the prior art, there is no problem that after replacing the TV, the old wall-mounted bracket cannot meet the wall-mounted size of the new TV and needs to be replaced. Moreover, when replacing the TV, quick disassembly can be achieved, which can greatly reduce the operation time, which is both convenient and fast.

Detailed implementation manners

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figure 1-5 , the present invention provides a magnetic adsorption holding assembly, including a mounting shell, a first fixed shell 2, a lifting mechanism 3, a rotating rod 4, an adjusting mechanism 5, a C-shaped frame 6, a second fixed shell 7, a rotating block 8, a rotating mechanism 9 and a plug-in block 10.

[0022] The first fixed shell 2 is vertically movably installed inside the mounting shell 1. A lifting mechanism 3 for lifting the first fixed shell 2 is arranged inside the mounting shell 1. A rotating rod 4 is rotatably installed inside the first fixed shell 2. An adjusting mechanism 5 for driving the rotating rod 4 is arranged inside the first fixed shell 2. A C-shaped frame 6 is fixedly installed on the outer wall of the rotating rod 4. A second fixed shell 7 is fixedly installed on one side of the C-shaped frame 6. A rotating block 8 is rotatably installed inside the second fixed shell 7. A rotating mechanism 9 for rotating the rotating block 8 is installed inside the second fixed shell 7. A plug-in block 10 is fixedly connected to one side of the rotating block 8.

[0023] It is convenient for the lifting mechanism 3 to drive the first fixed shell 2 to move up and down inside the mounting shell 1. The adjusting mechanism 5 can drive the rotating rod 4 and the C-shaped frame 6 fixedly installed on its outer wall to rotate up and down. The rotating mechanism 9 can drive the rotating block 8 to rotate, and drive the plug-in block 10 to adjust the left and right angles through the rotating block 8.

[0024] In this embodiment, as Figure 3As shown in the figure, the lifting mechanism 3 includes a lifting motor 31. The lifting motor 31 is set as a forward and reverse stepping motor. The lifting motor 31 is fixedly installed at the center of the bottom of the installation shell 1. One end of the output shaft of the lifting motor 31 penetrates through the installation shell 1 and is fixedly sleeved with a first driving gear 32. Both sides of the first driving gear 32 are engaged with a first driven gear 33. A threaded rod 34 is fixedly inserted inside each of the two first driven gears 33. The outer walls of the two threaded rods 34 are both threadedly connected with a lifting block 35. One side of each of the two lifting blocks 35 is fixedly connected to the side walls of both sides of the first fixed shell 2. It is convenient to drive the first driving gear 32 to engage with the two first driven gears 33 through the lifting motor 31, drive the two threaded rods 34 to rotate through the two first driven gears 33, and then make the lifting blocks 35 threadedly connected to the outer walls of the two threaded rods 34 move synchronously, thereby driving the first fixed shell 2 to move up and down in the installation shell 1.

[0025] Furthermore, as Figure 2 and 3 shown, the two threaded rods 34 are symmetrically and rotatably installed inside the installation shell 1, and the first driven gear 33 is located on the outer wall at the bottom of the threaded rod 34.

[0026] It should be noted that, as Figure 3 shown, a section of non-threaded area is reserved on both the top and bottom outer walls of the threaded rod 34 to prevent the lifting block 35 from driving the first fixed shell 2 to rise to the top of the installation shell 1 or drop to the bottom of the installation shell 1, and to prevent contact. That is, when the first fixed shell 2 is lifted to the highest position, there is a gap between the adjusting motor 52 in the adjusting mechanism 5 and the inner top of the installation shell 1. When the first fixed shell 2 drops to the lowest position, the bottom of the first fixed shell 2 will not contact the top of the first driving gear 32 and the output shaft of the lifting motor 31.

[0027] In a further preferred embodiment, as Figure 3 and 4 shown, the adjusting mechanism 5 includes a worm 51. The worm 51 is rotatably installed inside the first fixed shell 2. The top of the worm 51 penetrates through the first fixed shell 2 and is fixedly connected to an adjusting motor 52. The adjusting motor 52 is set as a forward and reverse stepping motor. One side of the worm 51 is engaged with a worm gear 53. The worm gear 53 is fixedly sleeved at the center of the outer wall of the rotating rod 4. It is convenient to drive the worm 51 to engage with the worm gear 53 through the adjusting motor 52, and drive the rotating rod 4 and the U-shaped frame 6 fixedly installed on its outer wall to rotate up and down, so as to adjust the up and down viewing angle of the LCD TV body 13.

[0028] It should be noted that the up and down rotation angle of the U-shaped frame 6 is controllable, and it cannot drive the second fixed shell 7 to touch the first fixed shell 2.

[0029] It is worth mentioning that the worm wheel 53 and the worm 51, as important components of mechanical transmission, have a unique structure and working principle. They realize the transmission of power and motion through a specific meshing method, and have the characteristics of large transmission ratio, high load-bearing capacity, smooth transmission, self-locking, etc. When the lead angle of the worm is smaller than the equivalent friction angle between the meshing gear teeth, the mechanism has self-locking property, that is, only the worm can drive the worm wheel, but the worm wheel cannot drive the worm. This feature is particularly important in occasions requiring safety protection such as lifting machinery.

[0030] Further, such as Figure 3 and 4 As shown, the rotating mechanism 9 includes a rotating shaft 91, which is rotatably mounted inside the second fixed shell 7, and a rotating block 8 is fixedly sleeved on the outer wall of the rotating shaft 91. A second driven gear 92 is fixedly sleeved on the top outer wall of the rotating shaft 91, and a second driving gear 93 is meshed on one side of the second driven gear 92. A rotating motor 94 is connected to the inside of the second driving gear 93, so that the second driving gear 93 is driven to mesh with the second driven gear 92 by the rotating motor 94. The rotating shaft 91 is driven to rotate by the second driven gear 92, and the rotating block 8 fixedly mounted on its outer wall can be driven to rotate.

[0031] It is worth noting that the angle at which the rotating block 8 is driven by the rotating shaft 91 to rotate left and right is controllable, and the plug-in block 10 cannot touch the second fixed shell 7, especially the LCD TV body 13 is prevented from touching the wall.

[0032] Preferably, Figure 4 As shown, the rotating motor 94 is fixedly installed on one side inner wall of the second fixed shell 7 through a bracket. The rotating motor 94 is configured as a forward and reverse stepping motor. One end of the output shaft of the rotating motor 94 is fixedly inserted into the interior of the second driving gear 93, so that the rotating motor 94 can be supported and installed by the bracket.

[0033] In addition, if Figure 5 As shown, a plug-in slot 11 is provided on the plug-in block 10, and an electromagnet 12 is fixedly embedded on the inner wall of one side of the plug-in slot 11. The electromagnet 12 is a device that generates electromagnetic energy when powered on.

[0034] It is worth noting that if Figure 1 and 2 As shown, two groups of protective plates 16 are symmetrically fixedly installed on one side of the mounting shell 1. The two groups of protective plates 16 are respectively located on both sides of the first fixed shell 2, and the side walls of the first fixed shell 2 are slidably connected to one side of the two groups of protective plates 16.

[0035] A liquid crystal television device includes a magnetic holding assembly and a liquid crystal television body 13. A mounting plate 14 is fixedly mounted on one side of a back plate of the liquid crystal television body 13, and a plug-in frame 15 is fixedly mounted on one side of the mounting plate 14.

[0036] It is worth noting that one side of the plug-in frame 15 is matched with the interior of the plug-in slot 11 .

[0037] Further, such as Figure 1 and 5 As shown, one side of the plug-in frame 15 is slidably plugged into the inside of the plug-in slot 11, and one side wall of the plug-in frame 15 is magnetically connected to the electromagnet 12, so that the plug-in frame 15 can be magnetically attracted by energizing the electromagnet 12, thereby improving the fixing effect of the LCD TV body 13 and realizing the rapid disassembly and assembly of the LCD TV body 13.

[0038] Working principle: By plugging the plug-in frame 15 on the mounting plate 14 on one side of the LCD TV body 13 into the plug-in slot 11 on the plug-in block 10, the plug-in frame 15 is magnetically attracted by energizing the electromagnet 12, so as to improve the fixing effect of the LCD TV body 13 and realize the rapid disassembly and assembly of the LCD TV body 13.

[0039] When the LCD TV body 13 needs to be adjusted, the lifting motor 31 in the lifting mechanism 3 drives the first driving gear 32 to mesh with the two sets of first driven gears 33, and the two sets of threaded rods 34 are driven to rotate through the two sets of first driven gears 33, so that the lifting blocks 35 threadedly connected to the outer walls of the two sets of threaded rods 34 move synchronously, and then the first fixed shell 2 is driven to move up and down in the mounting shell 1, so that the height of the LCD TV body 13 can be adjusted. The adjusting motor 52 in the adjusting mechanism 5 drives the worm 51 to mesh with the worm wheel 53, and the rotating rod 4 and the shaped frame 6 fixedly installed on the outer wall thereof are driven to rotate up and down through the worm wheel 53, so that the height of the LCD TV body 13 can be adjusted. The vertical viewing angle of the LCD TV body 13 is adjusted. The rotating motor 94 in the rotating mechanism 9 drives the second driving gear 93 to mesh with the second driven gear 92. The second driven gear 92 drives the rotating shaft 91 to rotate, which can drive the rotating block 8 fixedly installed on the outer wall to rotate. The LCD TV body 13 plugged into the plug-in block 10 is driven by the rotating block 8 to adjust the left and right angles, thereby realizing automatic adjustment of the LCD TV body 13 at multiple angles, so that the user can adjust the viewing angle of the LCD TV body 13 according to the needs, which can effectively improve the viewing effect of the LCD TV body 13 and facilitate people's use.

[0040] This application document is mainly used to protect the structure, shape and their combination, so this application document no longer explains the control method and circuit connection in detail. The device is powered by a built-in power supply or an external power supply.
