[0026] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by those skilled in the art to which the invention belongs.

[0027] like Figure 1-6 As shown, this embodiment provides a slide rail screen display system, including a background display piece 100, a display screen 400 and a slide rail assembly, wherein the display screen 400 is arranged in front of the background display piece 100 through the slide rail assembly;

[0028] The background display piece 100 includes a supporting substrate; the supporting substrate is a building wall or a background board, and graphic information is arranged on the surface of the supporting substrate.

[0029] The slide rail assembly includes a slide rail arranged transversely along the support base, the slide rail includes a first slide rail 200 near the top end of the support base and a second slide rail 300 near the bottom end of the support base, the display screen 400 is slidably connected with the first slide rail 200 and the second slide rail 300, the top end of the display screen 400 is provided with a first sliding member 410 matching the first slide rail 200, and the bottom end of the display screen 400 is provided with a second sliding member 420 matching the second slide rail 300;

[0030] The second slide rail 300 is also provided with a driving mechanism for driving the display screen 400, the driving mechanism includes a driving wheel and a driven wheel arranged at both ends of the second slide rail 300, a synchronous belt 510 is arranged between the driving wheel and the driven wheel, the synchronous belt 510 circulates and rotates in the second slide rail 300, the driving wheel is driven by the motor 500, and the second sliding member 420 is provided with a clearance hole 422 for the synchronous belt 510 to pass through;

[0031] The second sliding member 420 is provided with a clamping mechanism at a position corresponding to the clearance hole 422, and the clamping mechanism includes a fixed member 630 and a movable member 600 located on both sides of the clearance hole 422, and the fixed member 630 and the movable member 600 enclose a clamping space for clamping the synchronous belt 510, and a control member for pushing the movable member 600 is also provided in the clearance hole 422, and a return spring 610 is also provided between the movable member 600 and the side wall of the clearance hole 422.

[0032] The display screen 400 can move back and forth in front of the background display piece 100 along with the slide rail assembly. Sensing points are set at corresponding positions of the background display piece 100. When the display screen 400 slides to the corresponding sensing points, the content corresponding to the background display piece 100 is displayed, which helps visitors to understand the content displayed by the background display piece 100 in more detail. The display position is more free and targeted. The driving mechanism can automatically drive the display screen 400 to move, which is more accurate and smoother than manual operation. When continuous display or cyclic display is not required, the display screen 400 can be disconnected from the driving mechanism through the control component, and then the display screen 400 can be manually pushed to a specific position, which is suitable for use in real-person explanations.

[0033] As another preferred embodiment, the display screen 400 is powered by a built-in battery, a charging port is provided on the side of the display screen 400, a charging device 700 is fixedly provided at the end of the support base corresponding to the charging port, and the charging device 700 and the charging port are electrically connected via a magnetic attraction mechanism. An external power supply is avoided, and the structure is simplified. When the display screen 400 is not needed, the motor 500 drives the synchronous belt 510 to bring the display screen 400 to the end of the slide rail assembly for charging to avoid insufficient power during use.

[0034] See also Figure 3-5 In order to better lock and unlock the movable part 600, the movable part 600 is a plate part, the return spring 610 is located at both ends of the movable part 600, the control part is located in the middle of the movable part 600, and the control part is a rotatable cam 621. The rotating shaft 620 of the cam 621 is perpendicular to the horizontal plane where the movable part 600 moves. The rotating shaft 620 of the cam 621 extends out of the second sliding part 420 and an operating hand wheel 622 is provided at the extended part. When the protruding part of the cam 621 is rotated to the movable part 600, the movable part 600 will be pushed toward the fixed part 630 to clamp the synchronous belt 510. Conversely, when the protruding part of the cam 621 is rotated to face away from the movable part 600, the movable part 600 retreats under the pull of the return spring 610, so that the synchronous belt 510 can freely pass through the clearance hole 422, that is, when the display screen 400 is manually pushed, there will be no resistance from the synchronous belt 510, which also ensures that the driving mechanism will not be affected by external forces.

[0035] See also Figure 4-5 As another preferred embodiment, the tooth surface of the synchronous belt 510 faces the fixed part 630, and the fixed part 630 is provided with a butt joint tooth matching the tooth shape of the synchronous belt 510 on the side facing the synchronous belt 510, and the smooth surface of the synchronous belt 510 faces the movable part 600, and a buffer layer is provided on the side of the movable part 600 opposite to the synchronous belt 510. The butt joint tooth and the buffer layer can reduce the damage to the tooth shape of the synchronous belt 510.

The parts on both sides corresponding to the sliding channel are provided with pulleys 421. The upper part of the power groove has an opening, and the control member can be better operated at the upper part, and the hand wheel of the control member extends out of the power groove.

[0037] In order to better drive the synchronous belt 510, the motor 500 is a stepper motor, and the operation of the stepper motor can be precisely controlled, so that the display screen 400 can slide precisely under the pull of the synchronous belt 510. The motor 500 is arranged on the support base near the second slide rail 300, and a transmission mechanism is arranged between the motor 500 and the driving wheel.

[0038] In order to make the synchronous belt 510 move more smoothly, guide wheels are provided at both ends of the power slot corresponding to the synchronous belt 510 to avoid friction between the synchronous belt 510 and the inner wall of the power slot.

[0039] See also Figure 2 As another preferred embodiment, the first slide rail 200 has a U-shaped slide groove, and both sides of the U-shaped slide groove are provided with limiting steps 210 extending toward the center, and the first sliding member 410 is provided with a noise reduction roller 411 at a position corresponding to the limiting step 210.
