[0062] The sliding screen realizes screen expansion and contraction by sliding, and can provide richer screen ratios and more flexible display experience during the sliding process, and has a wide application prospect in the field of new energy vehicles and the like.

[0063] The inventors have found through long-term research that the current sliding screen lacks effective support for the screen body during the sliding process, and since the screen body is a flexible screen, the lack of effective support will affect the flatness of the screen body, and long-term use may cause the screen body to deform or be damaged, affecting the display effect.

[0064] Based on this, the present application provides a sliding screen solution to solve the above problems.

[0065] Please refer to Figures 1-4 Fig. 1 shows a sliding display device provided by an embodiment of the present application, which comprises a support 1, a first rotating shaft 2, a sliding support mechanism 3, a flexible screen 4 and a driving mechanism 5.

[0066] The first rotating shaft 2 is arranged on the support 1, the sliding support mechanism 3 comprises a first sliding plate 31, a transmission mechanism and a second sliding plate 33, the transmission mechanism is arranged around the first rotating shaft 2, and the transmission mechanism is further connected with the first sliding plate 31 and the second sliding plate 33; the two ends of the flexible screen 4 are connected with the first sliding plate 31 and the second sliding plate 33 respectively, the side of the transmission mechanism away from the first rotating shaft 2 abuts against one side of the flexible screen 4 and supports the flexible screen 4; the first sliding plate 31 and the second sliding plate 33 are both connected with the driving mechanism 5, the driving mechanism 5 drives the first sliding plate 31 and the second sliding plate 33 to move, and drives the transmission mechanism and the flexible screen 4 to move around the first rotating shaft 2.

[0067] The sliding display device 100 provided in the present application is moved by the first sliding plate 31 and the second sliding plate 33, and drives the chain belt 32 and the flexible screen 4 to rotate around the rotating shaft, which is beneficial to keep the flexible screen 4 in a tensioned state all the time, and improves the flatness and display effect of the flexible screen 4.

[0068] In the sliding process, the size of the flexible screen 4 on the visual front changes constantly, when the flexible screen 4 is completely slid to the visual front, the flexible screen 4 displays as a complete large screen, and when the flexible screen 4 is not completely slid to the visual front, the flexible screen 4 on the non-visual front can be selected to display or not to display.

[0069] Specifically, since the area of the flexible screen 4 in contact with the first rotating shaft 2 is in a bent state, and the bent area of the flexible screen 4 changes constantly in the sliding process, the present embodiment is in abutment with the flexible screen 4 through the transmission mechanism, which avoids affecting the flatness of the flexible screen 4 due to lack of support, and avoids using glue and the like to fix the flexible screen 4, so as to ensure that the internal force of the structure can be uniformly transmitted to the flexible screen 4 through the transmission mechanism, so that the flexible screen 4 is uniformly stressed as a whole, which effectively prolongs the service life of the flexible screen 4 while ensuring the flatness of the flexible screen 4.

Further, the second sliding plate 33 is provided with a waist-shaped hole 331 connected to the non-display area 42, which is used to absorb the tolerance in the assembly process, to ensure that the flexible screen 4 is fully stretched and fully compliant with the chain belt 32, and to ensure the flatness of the flexible screen 4 after assembly.
