Since the seventh transmission member 1624 and the fifth transmission member 1623 are screwed, the seventh transmission member 1624 is slid on the fifth transmission member 1623 along the axial direction of the fifth transmission member 1623 while the seventh transmission member 1624 is rotated about the rotation shaft assembly 12, The sliding of the seven transmission members 1624 causes the first plate 142 to move toward the direction of the spindle assembly 12. Similarly, the displacement between the second plate 144 and the second transmission assembly 164 is the same. The first plate 142 and the first transmission assembly 162, the second plate 144 and the second transmission assembly 164 cooperate to promote the flattening of the support structure 10.

The effect of opening the second accommodation space 1442 in the second plate 144 is also the same.

In the embodiment of the present application, the first transmission assembly 162 includes a first sleeve 1625. The first sleeve 1625 is rotatably coupled to the first shaft 121 and the fifth transmission member 1623. The first sleeve 1625 is rotatably coupled to the first shaft 121. The formed transmission axis is different from the transmission axis formed by the rotational connection of the first sleeve 1625 and the fifth transmission member 1623; the second transmission assembly 164 includes a second sleeve 1645, and the second sleeve 1645 is rotatably coupled to the second shaft 122 and The sixth transmission member 1643 is different from the transmission shaft formed by the rotational connection of the second sleeve 1645 and the second shaft 1224 to the second shaft 1645 and the sixth transmission member 1643. The arrangement of the first sleeve 1625 and the second sleeve 1645 ensures the structural stability of the support structure 100 when the first plate 142 and the second plate 144 are rotated.

Specifically, referring to FIG. 23, the first sleeve 1625 is substantially L-shaped, and the first sleeve 1625 includes a first portion 162g and a second portion 162h. The first portion 162g is a short portion of the first sleeve 1625, and the second portion 162h The first portion 162g is substantially perpendicular to the second portion 162h, and the first portion 162g is substantially perpendicular and rotationally coupled to the second shaft 1214, that is, the first rotating shaft 121, and the second portion 162h and the fifth transmission member 1623 are the long portions of the first sleeve 1625. The connection is substantially perpendicular and rotationally coupled between the second transmission member 1622 and the transmission portion 162c of the fifth transmission member 1623. Referring to FIG. 13, it can be understood that since the first sleeve 1625 is substantially L-shaped and the first portion 162g is substantially perpendicular to the second portion 162h, the transmission shaft formed by the first sleeve 1625 and the first shaft 121 is rotatably connected along the Y. In the axial direction, the transmission shaft formed by the first sleeve 1625 and the fifth transmission member 1623 is fixedly connected in the X-axis direction, that is, the transmission shaft formed by the first sleeve 1625 and the first rotation shaft 121 is rotatably connected with the first sleeve 1625. The drive shaft formed by the rotational connection with the fifth transmission member 1623 is also substantially perpendicular. The second bushing 1645 has a similar structure to the first bushing 1625 and therefore will not be deployed in detail.

The sleeve 1625 and the second sleeve 1645 are not damaged. When the support structure 10 is folded and flattened, the first sleeve 1625 and the second sleeve 1645 can exert a force on the first plate 142 and the second plate 144, thereby promoting the rotation process of the support structure 10 and making the support structure 10 more stable.

Specifically, taking the first plate 142 as an example, when the first bushing 1625 is received in the third receiving space 1424, the rotation of the first plate 142 about the rotating shaft assembly 12 can drive the first bushing 1625 to synchronously rotate the rotating shaft assembly. 12 is rotated. At this time, when the first plate 142 is rotated, the second transmission member 1622 and the fifth transmission member 1623 are also driven to rotate relative to the first transmission member 1621. Since the first sleeve 1625 and the first rotating shaft 121 are rotatably connected, the first sleeve 1625 and the fifth transmission member 1623 are rotatably connected, and therefore, the arrangement of the first sleeve 1625 does not hinder the first plate 142 and the second transmission member 1622. And rotation of the fifth transmission member 1623. The second bushing 1645 is received in the fourth receiving space 1444.

By designing the first protrusion 162b and the first limiting slot 1216, the second protrusion 164b and the second limiting slot 1226, the reverse rotation of the rotating shaft assembly 12 is avoided, for example, in a state of full deployment or 0 degree. Continue to bend in the unfolding direction to avoid erroneous operation of damaging the support structure 10 or even damaging the flexible components.

In an embodiment of the present application, the support structure 10 includes a damper assembly 18 that connects the shaft assembly 12 with the transmission assembly 16 for maintaining the drive travel of the transmission assembly 16 to enable the support plate 14 to remain in the deployed state.
