Referring to fig. 1, the stretching portion is connected and fixed to the free end 12 of the flexible display panel 10, and can drive the free end 12 of the flexible display panel 10 to move. Specifically, a pulling force may be applied to the stretching end for the user, and after the stretching end receives the pulling force applied by the user, the free end 12 of the flexible display panel 10 is driven to move in a direction away from the curling storage portion 20, so that the flexible display panel 10 is in an unfolded state to display. The test machine may apply a force to the stretching portion.
Referring to fig. 1 and 2, the tension limiting portion 40 is disposed between the curl accommodating portion 20 and the stretching portion 30, and specifically, one end of the tension limiting portion 40 is connected and fixed to the housing 22 of the curl accommodating portion 20, and the other end is connected and fixed to the stretching portion 30. The tension restricting portion 40 is extendable and retractable to change the length thereof. When the stretching part 30 receives a first force directed toward or away from the curl accommodating part 20 and the first force is greater than a preset threshold value, the tensile force limiting part 40 provides a second force to the stretching part 30 in a direction opposite to the first force.
The tension limiting part includes a telescopic base member 41 and at least one telescopic member 42. The telescoping member 42 includes a first bottom surface 422, a barrel wall 421, and a second bottom surface 423.

The tension limiting portion provides a second force to the stretching portion opposite the first force by creating an air pressure differential between the air lumen 424 and the outside atmosphere. For example, as shown in fig. 3, the curl receiving portion 20 is fixed in position and the stretching portion receives a first force in a first direction. The flexible display device 100 changes from state one to state two. The stretching end 30 transmits the first acting force to the flexible display panel 10 and the tension limiting portion 40, so as to drive the flexible display panel 10 and the tension limiting portion 10 to move in the first direction. One end of the tensile force limiting portion 40 connected to the stretching portion 30 moves in the first direction by the first acting force, that is, the tensile force limiting portion 40 extends. At this time, the telescopic base member 41 moves in the first direction relative to the telescopic member 42, so that the volume of the air cavity 424 is increased, and the air pressure of the air cavity 424 is lower than the external atmospheric pressure, the air flow hole 4231 flows air into the air cavity 424 from the outside under the action of the pressure difference, when the speed of the flowing air reaches the maximum air flow rate of the air flow hole 4231, if the pressure difference still exists at this time, the external atmospheric pressure applies pressure in the second direction to the telescopic base member 41, and the pressure applied to the telescopic base member 41 is transmitted to the stretching part 30 connected thereto, that is, the second acting force, through the telescopic base member 41. When the stretching portion 30 is acted upon by a first acting force larger than a preset threshold value by the tensile force limiting portion 40, the tensile force limiting portion provides a second acting force to the stretching portion 30 in a direction opposite to the first acting force. In this way, the speed and the acceleration of the movement of the stretching portion 30 are relatively small, so that the flexible display panel 10 is prevented from being damaged by tearing due to the impact of a large acting force, and the reliability of the flexible display device 100 is improved. The aperture of the air flow hole 4231 is set according to the preset threshold. In addition, when the flexible display panel 10 is driven by the stretching portion 30 to extend out of the curling storage portion 20, the tension limiting portion 40 also supports the flexible display panel 10.
In another embodiment, referring to fig. 4, the number of the expansion pieces of the tension limiting portion is N, and the expansion pieces are i-th-stage expansion pieces in sequence, the expansion base piece 41 passes through the through hole 4221a of the 1 st-stage expansion piece 42a, the i-th-stage expansion piece 42a passes through the through hole 4221b of the i + 1-stage expansion piece 42b, and the i-th-stage expansion piece 42a and the through hole 4221b of the i + 1-stage expansion piece 42b are in a sealed slidable connection, where N is greater than or equal to 2, i is greater than or equal to 1 and less than or equal to N, and N, i is an integer.
