[0041] The preferred embodiments of the present application are given below in conjunction with the accompanying drawings and described in detail.

[0042] As shown in Figures 1 and 2, a sliding mechanism according to a preferred embodiment of the present application is used to move a large screen 10 in front of the dashboard of a vehicle V. It should be understood that this usage position is merely exemplary and not limiting. The current position of screen 10 in vehicle V is depicted by a solid line, and screen 10 can be moved from this current position to another position depicted by a dashed line.

[0043] As shown in FIG3 , a sliding mechanism according to a preferred embodiment of the present application includes a pulley system 4 and a guide rail 5 . A large-sized screen 10 (see FIG2 ) is mounted and fixed on the pulley system 4 (also referred to as a screen connection device), and the guide rail 5 is fixedly mounted on, for example, an instrument panel. The pulley system 4 is slidably mounted on the guide rail 5 to enable left and right sliding of the large-sized screen 10 (see FIG2 ). FIG3 shows the two end positions of the pulley system 4 on the guide rail 5 , and the pulley system 4 can slide back and forth between these two end positions.

[0044] As shown in Figures 4 and 5, the sliding mechanism according to a preferred embodiment of the present application further includes a slider device 2 and a slide bar 7, wherein the slider device 2 is fixedly mounted on the pulley system 4, and the slide bar 7 is fixedly mounted on the guide rail 5. The pulley system 4 can slide left and right under the guidance of the slide bar 7 and achieve tensioning with the help of the slider device 2 and the guide rail 5, ensuring that the pulley system 4 and the large-sized screen 10 (see Figure 2) carried thereon do not shake in the vertical direction (i.e., the Z direction), while preventing problems such as jamming and vibration noise caused by accumulated tolerances during the manufacturing process of the sliding mechanism. It should be understood that regardless of whether the pulley system 4 slides or whether sliding friction is generated between it and the guide rail 5, the slider device 2 is always in a tensioned state when the pulley system 4 is installed on the guide rail 5. The pulley system 4 is rotatably supported about the slide rod 7, but is not movably supported along the slide rod 7 or along the guide rail 5. The slider device 2 restricts the rotation of the pulley system 4 about the slide rod 7. Due to the support of the pulley system 4 by the slide rod 7 and the interaction between the slider device 2 and the slide rod 7, the pulley system 4 can only slide linearly, especially linearly, in the extension direction of the guide rail 5. The guide rail 5 has a guide groove 51 for receiving the slider device 2, and the guide groove 51 has two opposite groove side surfaces.

[0045] As shown in Figure 6, the slider assembly 2 includes a first slider (which in the present embodiment is configured as an upper slider) 21, two spring clips 22, two spring clip covers 23, and two second sliders (which in the present embodiment is configured as lower sliders 24). The adjacent ends of the two spring clips 22 and the two second sliders, or lower sliders 24, are fixedly secured to the pulley system 4 via the first slider, or upper slider 21, while the distal ends of the two spring clips 22 and the two second sliders, or lower sliders 24, are fixedly secured via the spring clip covers 23. Thus, the ends of the spring clips 22 are connected to the spring clip covers 23 and the associated sliders 21 and 24, respectively. Specifically, a portion of the upper slider 21, one of the spring clips 22, one of the spring clip covers 23, and one of the lower sliders 24 form a first slider structure X; another portion of the upper slider 21, another spring clip 22, another spring clip cover 23, and another of the lower sliders 24 form a second slider structure Y. Each spring clip cover 23 has a fixing element 231, particularly a screw. The fixing element 231 passes through the mounting hole 222 at the outer end of an associated spring plate 22 and the mounting hole 244 at the outer end of an associated lower slide 24 and is installed in the mounting hole 41 (see FIG. 4 ) of the pulley system 4 .

[0046] As shown in Figure 7, the upper slider 21 includes a connecting portion 211 and an upper shock-absorbing pad 212. The adjacent ends of the two spring clips 22 and the two lower sliders 24 are secured together via the connecting portion 211. To this end, the upper slider 21 has two pins 214, each of which is received in an opening 221 at the inner end of an associated spring clip 22 and an opening 243 at the inner end of an associated lower slider 24. In the present embodiment, the openings 221 and 243 are configured as open elongated holes. Alternatively, these openings can be configured as closed elongated holes or circular holes. The upper shock-absorbing pad 212 is fixedly mounted on the connecting portion 211 to provide a self-lubricating upper contact point between the slider assembly 2 and the guide rail 5, thereby eliminating vibration and operating noise. The upper shock-absorbing pad 212 rests against the upper side of the guide slot 51 of the guide rail 5. The upper slider 21 further has a mounting hole 213 so as to mount the upper slider 21 to the pulley system 4 by means of a fixing element 25 (see FIG. 9 ), in particular a screw, passing through the mounting hole 213 .

[0047] As shown in Figure 8, the lower slider 24 includes a support portion 241 and a lower shock-absorbing pad 242. The support portion 241, located in the middle of the lower slider 24, acts on the spring plate 22. The lower shock-absorbing pad 242, located in the middle of the lower slider 24 opposite the support portion 241, provides a self-lubricating lower contact point between the slider assembly 2 and the guide rail 5, eliminating vibration and noise during operation. The support portion 241 bends the spring plate 22. The restoring force of the spring plate 22 supports the lower slider 24, thereby creating tension between the lower shock-absorbing pad 242 and the guide rail 5. The lower shock-absorbing pad 242 rests on the lower side of the guide groove 51 of the guide rail 5.

[0048] As shown in Figure 9, the slider assembly 2 contacts the guide rail 5 (specifically, the side surface of the guide groove 51 of the guide rail 5) at the upper contact point via the upper shock-absorbing pad 212 of the upper slider 21. At this upper contact point, the elastic force of the spring 22 generates an interaction force between the spring 22 and the guide rail 5, achieving tension. Specifically, the upper contact point between the spring cover 23 of the first slider structure X and the guide rail 5 is referred to as the first connection point, the upper contact point between the upper slider 21 of the first slider structure X and the guide rail 5 is referred to as the second connection point, the upper contact point between the upper slider 21 of the second slider structure Y and the guide rail 5 is referred to as the third connection point, and the upper contact point between the spring cover 23 of the second slider structure Y and the guide rail 5 is referred to as the fourth connection point. At least one of the openings at the first and second connections of the spring 22 of the first slider structure X is a waist-shaped hole or an open hole, allowing the spring 22 to elastically deform between the first and second connections, thereby achieving tension between the first slider structure X and the guide rail 5. At least one of the openings at the third and fourth connections of the spring clip 22 of the second slider structure Y is a waist-shaped hole or an open hole, allowing the spring clip 22 to elastically deform between the third and fourth connections, thereby achieving tension between the second slider structure Y and the guide rail 5. Furthermore, the slider assembly 2 contacts the guide rail 5 (specifically, the side surface below the guide groove 51 of the guide rail 5) at the lower contact point via the lower shock-absorbing pad 242 of the lower slider 24. At this lower contact point, the spring clip 22 generates an interaction force with the guide rail 5, achieving tension. Specifically, between the first and second connections, the spring clip 22 of the first slider structure X exerts a supporting force on the lower slider 24 through the elastic force of its deformation. Between the third and fourth connections, the spring clip 22 of the second slider structure Y exerts a supporting force on the lower slider 24 through the elastic force of its deformation. In this way, the spring sheet 22 can cause the upper slider 21 and the lower slider 24 to respectively abut against the guide rail 5, thereby providing a compressible elastic force in the Z direction to provide tension for the pulley system 4 (see Figure 5) when sliding on the guide rail 5. It should be understood that the material selection of the guide rail 5 and the upper and lower anti-vibration pads 212, 242 can be used to achieve noise reduction during use. For example, when the guide rail 5 is metal, the upper and lower anti-vibration pads 212, 242 can be plastic; when the guide rail 5 is plastic, the upper and lower anti-vibration pads 212, 242 can be metal.

[0049] Compared to known prior art tensioning mechanisms such as rollers, the sliding mechanism of the present application can be used in a variety of application scenarios. In addition to the linear guide rail 5 shown above, the sliding mechanism can also be used for curved guide rails 5a. As shown in Figure 10, by simply adjusting the connection between the upper and lower sliders, the slider device 2 can also provide tension between the pulley system 4 and the guide rail 5. The surface 215 of each shock-absorbing pad 212, 242 facing the bottom of the guide groove 51 can be configured as a curved surface, which can be well adapted not only to linear guide rails but also to curved guide rails. It will be understood that Figure 10 only schematically depicts the curved direction of the guide rail 5, and the specific structure of the guide rail 5 can be implemented similarly to the linear guide rail 5 in the aforementioned embodiment.

[0050] In addition to manually driving the sliding mechanism to slide on the guide rail 5, the sliding mechanism's sliding motion can also be controlled by motor drive. As shown in Figures 11-13, the sliding mechanism assembly A includes a motor B and a cable mechanism C mounted on the guide rail 5. Motor B drives the pulley system 4 through the cable mechanism C, thereby causing the pulley system 4 to reciprocate on the guide rail 5. Here, motor B can rotate a winding drum D, which is mounted on the pulley system 4. The cable mechanism C includes two cables C1 and C2, each of which is fixed to the guide rail at one end and to the winding drum D at the other end. When the winding drum rotates in one rotational direction, the winding drum D drives the pulley system 4 to move along the guide rail in one direction of movement. When the winding drum rotates in the opposite rotational direction, the winding drum D drives the pulley system 4 to move along the guide rail in the opposite direction of movement.

[0051] In the embodiment shown in the accompanying drawings, the first slider is configured as an upper slider, and the second slider is configured as a lower slider. Alternatively, the first and second sliders can be arranged in reversed orientation; in other words, the first slider can be the lower slider and the second slider can be the upper slider. Furthermore, other orientations of the first and second sliders are possible. For example, the first and second sliders can be arranged side by side in a horizontal plane, with the first slider being the front slider and the second slider being the rear slider.

[0052] The above description is merely a preferred embodiment of the present application and is not intended to limit the scope of the present application. Various modifications are possible to the above embodiments of the present application. In other words, any simple, equivalent changes and modifications made in accordance with the claims and the description of the present application fall within the scope of protection of the claims of the present application. Anything not fully described in this application is conventional technology.
