And a limiting mechanism 25 arranged on one side of the stepped structure 23 far away from the support body 22 and used for limiting or releasing the limit of the telescopic mechanism 21. For example, when the telescopic mechanism 21 is completely disposed in the gap between the stepped structure 23 and the display module 1, the limiting mechanism 25 limits the telescopic mechanism 21 to prevent the telescopic mechanism 21 from sliding out of the stepped structure 23, and at this time, the length of the supporting device 2 is the minimum; when the limiting mechanism 25 is opened, that is, the limiting mechanism 25 is contacted with the telescopic mechanism 21 for limiting, the telescopic mechanism 21 slides on the stepped structure 23 due to the acting force of the elastic mechanism 24 on the telescopic mechanism 21, and then the elastic mechanism 24 partially slides out of the stepped structure 23, and at this time, the length of the supporting device 2 is the maximum value. In this way, the change of the length of the supporting devices 2 is realized, so that the distance between two adjacent supporting devices 2 is changed, the length of the bending area is changed, the display device has different lengths of the bending area when being bent outwards and bent inwards, and the outward bending and the inward bending of the same display device can be realized, so that different requirements of customers are met.
It is understood that the resilient mechanism 24 may be a spring or other component, and the invention is not limited to the specific type of resilient mechanism 24.
It is also understood that the limiting mechanism 25 may be a baffle or other component, and the invention is not limited to the specific type of limiting mechanism 25.
It can be understood that, when the limiting mechanism 25 has a limiting function on the telescopic mechanism 21, the limiting mechanism can be fixed on the stepped structure 23 in a magnetic attraction manner, or can be fixed in a buckling manner, and the invention does not limit how the limiting mechanism 25 is fixed.
In one embodiment of the invention, the support device 2 further comprises foam and a hinge 26. The foam is arranged on one or more of the following positions, the telescopic mechanism 21 is close to one side of the supporting body 22, and the telescopic mechanism 21 is close to one side of the limiting mechanism 25, so that the foam can play a role in buffering, and the telescopic mechanism 21 is prevented from being damaged due to overlarge elasticity of the elastic mechanism 24. The hinge 26 is provided on the stepped structure 23 and the stopper mechanism 25, and functions to movably link the stepped structure 23 and the stopper mechanism 25. For example, when stop gear 25 is the baffle, baffle and stair structure 23 are swing joint, and when the baffle is perpendicular to display module assembly 1, blocks the one end in the space between stair structure 23 and the display module assembly 1, can carry out spacingly to telescopic machanism 21, when the baffle is opened, no longer blocks the one end in the space between stair structure 23 and the display module assembly 1, can cancel the spacing to telescopic machanism 21. The limit and the relief limit of the telescopic mechanism 21 by the limit mechanism 25 can be realized by arranging the hinge 26, and the process is simple and easy to realize.
It will be appreciated that the step structure 23 and the limiting mechanism 25 can be movably connected by the hinge 26, and the step structure 23 and the limiting mechanism 25 can be movably connected by other methods, and the invention is not limited if the step structure 23 and the limiting mechanism 25 are movably connected.

The first protrusion is disposed at an end of the stepped structure 23 far from the support body 22, and the second protrusion is disposed at a side where the telescopic mechanism 21 and the stepped structure 23 contact each other. The first protrusion and the second protrusion are in contact to form a buckle assembly for blocking the sliding of the telescopic device. Specifically, when a part of the telescopic mechanism 21 slides out of the stepped structure 23, the first protrusion on the stepped structure 23 blocks the second protrusion on the telescopic mechanism 21, and the telescopic mechanism 21 cannot slide continuously, so that the telescopic mechanism 21 is prevented from sliding out of the stepped structure 23 and being separated from the stepped structure 23.
It will be appreciated that the telescoping mechanism 21 may be limited from sliding out entirely by providing the first and second protrusions to form a snap-fit assembly, or the telescoping mechanism 21 may be limited using other configurations, and the present invention is not limited to how the telescoping mechanism 21 is prevented from sliding out entirely out of the step structure 23.
