CONCRETE EMBODIMENT

[0020] The specific implementation scheme of the utility model will be described in detail with reference to the drawings.

[0021] Refer to Figs. 1 to 3The utility model provides a kind of folding three-screen assembly, including main screen 1, first vice screen 2 and second vice screen 3, first vice screen 2 and second vice screen 3 are rotatably connected in the both sides of main screen 1 and can be folded in succession on main screen 1, after first vice screen 2 and second vice screen 3 are folded, first vice screen 2 is between second vice screen 3 and main screen 1;Wherein, the bottom of main screen 1 can be provided with hinged seat, and hinged seat is hinged with server main body.Further, the main screen 1 is connected with the first vice screen 2, second vice screen 3 between by damping pivot, and the arbitrary angle of first vice screen 2 and second vice screen 3 when unfolding is conveniently kept by the setting of damping pivot.

[0022] First support limiting structure 4 is equipped between the main screen 1 and the first vice screen 2, for limiting the rotation angle of first vice screen 2 relative to main screen 1, so that when folding on main screen 1, it cannot continue to rotate after rotating to the specified angle, so that the screen surface of first vice screen 2 and main screen 1 will not be extruded, avoiding screen wear or damage. Second support limiting structure 5 is provided between the main screen 1 and the second vice screen 3, to limit the rotation angle of the second vice screen 3 relative to the main screen 1, so that when the second vice screen 3 continues to fold after the first vice screen 2 is folded, it cannot continue to rotate after rotating to the specified angle, without being extruded with the surface of the first vice screen 2.

[0023] In some embodiments, the support limiting structure and the hinged seat are staggered to avoid interference between them. The first support limiting structure 4 and the second support limiting structure have the same structure, and the first support limiting structure and the second support limiting structure are staggered in the up-down direction to avoid interference when moving.

[0024] Specifically, the support limiting structure includes a sliding groove 61 provided on the upper and lower sides of the first vice screen 2 and / or the second vice screen 3, and a support rod 62 hinged at one end to the upper and lower sides of the main screen 1. At this time, the support rod 62 in the first support limiting structure 4 and the support rod 62 in the second support limiting structure 5 are arranged in the up-down direction of the screen. The other end of the support rod 62 is hinged with a sliding shaft 63 that slides with the sliding groove 61. To facilitate the sliding of the sliding shaft 63 in the sliding groove 61, the sliding shaft 63 is provided with a plurality of rolling balls 631 that roll with the sliding groove 61 in the circumferential direction. The sliding groove 61 can be provided with a large cavity and a small opening, and the diameter of the inner end of the sliding shaft 63 is larger than the diameter of the outer end, so that it is partially limited in the sliding connection with the sliding groove 61, and the other end extends out of the sliding groove 61 and is hinged with the support rod 62.

[0025] The sliding groove 61 has an unfolding limiting part 611 near one end of the main screen 1 to limit the movement of the sliding shaft 63, and has a folding limiting part 612 near the other end to limit the movement of the sliding shaft 63. The unfolding limiting part 611 and the folding limiting part 612 can be any structure that limits the movement of the sliding shaft 63, such as a baffle, a fixed protrusion, etc. In this embodiment, the unfolding limiting part 611 and the folding limiting part 612 are respectively two end faces of the sliding groove 61 in the axial direction, i.e. the end face near one end of the main screen 1 is the unfolding limiting part 611, and the end face near the other end is the folding limiting part 612.

[0026] When folding the secondary screens on the main screen 1, first fold the first secondary screen 2 towards the main screen 1, and then fold the second secondary screen 3 towards the main screen 1. During the process of manually folding the secondary screens towards the main screen 1, one end of the supporting rod 62 rotates around the hinge point with the main screen 1, and at the same time, the other end of the supporting rod 62 drives the sliding shaft 63 to slide in the sliding groove 61 towards the folding limiting part 612. When the sliding shaft 63 slides to the position of the folding limiting part 612 of the sliding groove 61, the sliding shaft 63 cannot continue to slide away from the main screen 1, and due to the length limitation of the supporting rod 62, the secondary screens cannot continue to be pressed towards the main screen 1, thereby ensuring that the secondary screens cannot continue to press the adjacent screens. During the process of manually unfolding the secondary screens, one end of the supporting rod 62 still rotates around the hinge point with the main screen 1, and the other end of the supporting rod 62 drives the sliding shaft 63 to slide in the sliding groove 61 towards the unfolding limiting part 611. When the sliding shaft 63 slides to the position of the unfolding limiting part 611, the sliding shaft 63 cannot slide in the sliding groove 61 towards the main screen 1, and due to the length limitation of the supporting rod 62, the secondary screens cannot rotate relative to the main screen 1, thereby limiting the maximum unfolding angle of the secondary screens, and avoiding that the display surface of the secondary screens excessively rotates due to shaking or other reasons, which is not convenient for the user to watch.

[0027] In some embodiments, to further stabilize the folding angle or unfolding angle of the secondary screens, the unfolding limiting part 611 of the sliding groove 61 is provided with an unfolding positioning part for fixing the sliding shaft 63, and the folding limiting part 612 of the sliding groove 61 is provided with a folding positioning part for fixing the sliding shaft 63. The unfolding positioning part and the folding positioning part can have the same structure or different structures, as long as they can limit the movement of the sliding shaft 63 in the sliding groove 61. When the position of the sliding shaft 63 in the sliding groove 61 is fixed, the secondary screens cannot rotate relative to the main screen 1, thereby stabilizing the unfolded or folded state of the secondary screens.

[0028] In some embodiments, referring to Fig. 1 and Fig. 2The positioning part comprises first magnetic members 71 arranged on the side walls of the sliding groove 61, and the sliding shaft 63 is provided with second magnetic members 72 matched with the first magnetic members 71, and the two first magnetic members 71 are matched with the second magnetic members 72 to limit the unfolded or folded state of the secondary screen. The magnetic members can be magnets, and the position of the sliding shaft 63 is positioned by matching the first magnetic members 71 and the second magnetic members 72 to limit the rotation of the secondary screen. When the screen needs to be rotated, the first magnetic members 71 and the second magnetic members 72 are misaligned under the action of a larger external force to lose the positioning effect.

[0029] In some other embodiments, referring to Fig. 1 and Fig. 3 The positioning part comprises a positioning rod 81 movably arranged in the sliding shaft 63, an elastic member 82 and positioning grooves 83 arranged on the bottom walls of the two ends of the sliding groove 61, and the two positioning grooves 83 are matched with the positioning rod 81 to limit the unfolded or folded state of the secondary screen. One end of the elastic member 82 is fixed with a convex ring 811 on the positioning rod 81, and the other end is fixed with the inner wall of the side of the sliding shaft 63 away from the positioning groove 83, the inner extending end of the positioning rod 81 can be inserted and matched with the positioning groove 83, at this time, the position of the sliding shaft 63 can be fixed by inserting the positioning rod 81 into the positioning groove 83, when the screen needs to be rotated, the positioning rod 81 is pulled to compress the elastic member 82, so that the inner extending end of the positioning rod 81 is separated from the positioning groove 83, and the sliding shaft 63 can slide in the sliding groove 61.

[0030] In summary, by adopting the utility model, the maximum unfolding angle and folding angle of the secondary screen can be limited by the supporting and limiting structure, so that the secondary screen will not be excessively rotated and pressed on the adjacent screen when being folded, and each screen can be supported when being unfolded, thereby improving the stability and service life of the multi-screen assembly during use.
