In the present invention, the supporting plate 141 can be selected according to the requirement, so as to reduce the influence of the gap between the plates of the supporting plate 141 on the flexible display screen 2 to the maximum extent, and simultaneously support the laying of the flat cables.
Understandably, in the present invention, the installation manner between the supporting plate 141 and the sliding assembly 121 is not limited, and in an embodiment, as shown in fig. 10, both ends of the supporting plate 141 are bent to form a snap ring, the snap ring is sleeved on the first elastic member 1213 or the second elastic member 1214, and since the first elastic member 1213 or the second elastic member 1214 is sleeved on the positioning shaft 12114 of the intermediate groove 12112 of the sliding block 1211, the snap rings at both ends of the supporting plate 141 are sleeved on the positioning shafts 12114 of the sliding blocks 1211 at both ends of the casing assembly 11, thereby realizing the limitation of the positions of both ends, and completing the installation between the supporting plate 141 and the sliding block 1211.

As shown in fig. 1, when the supporting structure 1 is in a small size state (the sliding housing 111 and the connecting housing 112 are in a small size state with more overlap), the first housing 1111 and the second housing 1112 can wrap the connecting housing 1123 in the middle, all the supporting plates 141 of the supporting assembly 14 are in a close arrangement state, and the first elastic member 1213 and the second elastic member 1214 provided on the assembly of the sliding block 1211 are compressed to the maximum extent; the flexible display 2 has a larger area on each side, and the screen portion attached to the synchronizing shaft 132 is bent inside the housing assembly 11 (e.g. in the gap between the connecting housing 112 and the first housing 1111 and the second housing 1112). At this moment, flexible display screen 2 is curled shrink and has the display area of small area, but flexible display screen 2's whole volume occupation space reduces greatly, and the user of being convenient for carries, has promoted user and has used experience.
As shown in fig. 2, when the supporting structure 1 is in a large-size state (the sliding housing 111 and the connecting housing 112 are in a large-size state with less overlap, and the portions of the flexible display screen 2 that can be curled inside are gradually stretched along with the expansion of the first housing 1111 and the second housing 1112 on both sides until reaching the maximum size), the first housing 1111 and the second housing 1112 are respectively located at both side edges of the connecting housing 112, and at this time, all the supporting plates 141 of the supporting assembly 14 are in a state of being arranged in a gap, the compression amount of the first elastic member 1213 and the second elastic member 1214 arranged on the slider 1211 assembly is small, and the arrangement of the first elastic member 1213 and the second elastic member 1214 can ensure that the gap width between the supporting plates 141 is relatively stable. At this time, the flexible display screen 2 is stretched and unfolded to have a large-area display area, so that a high-quality display picture is provided conveniently, and the use experience of watching the display picture by a user is improved.
The above description is only an example of the supporting structure 1 of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
