[0047] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0048] Figures 1-4 This diagram illustrates a structural diagram of a liquid crystal screen lifting mechanism with a belt tensioning structure 310, according to an embodiment of this application. Figures 1-4 As shown, the LCD screen lifting mechanism may include:

[0049] Casing 100;

[0050] Lifting plate 200, the lifting plate 200 is mounted on the outer casing 100;

[0051] The belt assembly 300 is mounted on the housing 100 and drives the lifting plate 200 to move along the housing 100.

[0052] Pressure roller 400 is mounted on lifting plate 200 and presses against belt assembly 300;

[0053] Two tensioning pulleys 500 are mounted on the lifting plate 200 to tension the belt assembly 300.

[0054] In this embodiment, the lifting plate 200 moves along the outer shell 100 by being driven by the belt assembly 300. The two ends of the belt assembly 300 are tensioned on the outer shell 100, and the tensioning wheel 500 is set on the lifting plate 200. When the lifting plate 200 moves, the belt assembly 300 drives the lifting plate 200 to move. The tensioning wheel 500 tensions both sides of the belt assembly 300, and the pressure wheel 400 prevents the belt 310 from lifting, ensuring the stability of the belt assembly 300's movement.

[0055] Two tensioning rollers 500, in conjunction with the belt assembly 300, provide secondary tension to the belt 310 at the connection point of the lifting plate 200. The pressure roller 400 then presses down on the belt 310, ensuring that the belt 310 is always in contact with the pulley 330. This prevents the belt 310 from becoming loose at both ends, which would cause the belt 310 and the pulley 330 to not fit properly and affect the stability of the lifting plate 200's movement.

[0056] like Figures 1-4 As shown, in one embodiment,

[0057] The belt assembly 300 includes:

[0058] The belt 310 has two ends mounted on the housing 100, and both tension pulleys 500 are in contact with the belt 310.

[0059] Drive component 320, drive component 320 is mounted on lifting plate 200;

[0060] The pulley 330 is located on the output end of the drive assembly 320. The pressure roller 400 is in contact with the belt 310 and is located on the pulley 330.

[0061] In this embodiment, the pulley 330 lifts the belt 310, and with the cooperation of two tensioning pulleys 500, the belt 310 is always in contact with the pulley 330. The two tensioning pulleys 500 apply pressure to the belt 310, and the pulley 330 lifts the belt 310, thereby forming a tensioning structure. The pressure roller 400 is located above the pulley 330 and is in contact with the belt 310, pressing the belt 310. At the same time, it cooperates with the belt 310 to rotate. When the pulley 330 rotates, the belt 310 moves, and the belt 310 drives the pressure roller 400 to rotate. The distance between the pulley 330 and the pressure roller 400 is adapted to the thickness of the belt 310.

[0062] Specifically, two tensioning pulleys 500 are located above the belt 310, and the pulley 330 is located below the belt 310. The pulley 330, in conjunction with the tensioning pulleys 500, causes the belt 310 to form a "V" shape at the lifting plate 200.

[0063] The two tensioning pulleys 500 and the belt pulley 330 are arranged in a triangle.

[0064] Specifically, the centers of the two tensioning pulleys 500 are located on the same horizontal straight line, ensuring that the two tensioning pulleys 500 can tension the belt 310, thereby ensuring that the pulley 330 and the belt 310 are in contact.

[0065] like Figures 2-3 As shown, in one embodiment,

[0066] Driver component 320 includes:

[0067] The drive motor 321 has a pulley 330 on its output end, and the drive motor 321 is mounted on the lifting plate 200 via a motor bracket.

[0068] In this embodiment, the drive motor 321 drives the pulley 330 to rotate, thereby causing the lifting plate 200 assembly to move along the belt 310;

[0069] Specifically, the lifting plate 200 has a through hole for the belt 310 to pass through, ensuring that the belt 310 can pass through the lifting plate 200 so that the pulley 330 rotates and drives the lifting plate 200 to move along the belt 310.

[0070] like Figures 2-3 As shown, in one embodiment,

[0071] The protective shell 600 has two ends respectively mounted on the motor bracket and the lifting plate 200, forming a accommodating cavity between the protective shell 600 and the motor bracket for mounting the pressure roller 400.

[0072] In this embodiment, the pressure roller 400 is disposed in the accommodating cavity, and the protective shell 600 protects the pressure roller 400 to ensure its normal use. Multiple pressure rollers 400 can be provided, and the number of pressure rollers 400 is spliced ​​according to the width of the belt 310. At the same time, the width of the protective shell 600 can be adjusted according to the number of pressure rollers 400. The pressure roller 400 is disposed between the motor bracket and the protective shell 600 via a rotating shaft.

[0073] Specifically, the protective housing 600 has an L-shaped cross-section to form an accommodating cavity between the protective housing 600 and the motor bracket.

[0074] like Figure 1 As shown, in one embodiment, it further includes:

[0075] Display screen 700 is mounted on lifting plate 200 via bracket.

[0076] In this embodiment, the display screen 700 is raised and lowered within the housing 100 by the movement of the lifting plate 200. The top of the housing 100 has an opening. When in use, the top of the housing 100 is placed on the conference table, and the opening is located on the table and flush with the table. The movement of the lifting plate 200 drives the display screen 700 to move, which facilitates the retraction of the display screen 700. When not in use, the display screen 700 retracts into the housing 100.

[0077] In one implementation, it further includes:

[0078] The slide rail is mounted on the outer casing 100, and the lifting plate 200 is mounted on the slide rail.

[0079] In this embodiment, the movement of the lifting plate 200 is stabilized by setting the slide rail. An n-shaped slider can be set on the back of the lifting plate 200 to partially cover the slide rail, ensuring the stable operation of the lifting plate 200. The slide rail is set on the side of the belt 310, or two slide rails can be set to ensure the stable movement of the lifting plate 200.
