It can be understood that, in the present application, the connection between the flexible display screen 20 and the first frame body 31 and the second frame body 32 may be a direct connection or an indirect connection. The direct connection means that the flexible display screen 20 is directly connected to the first frame 31 and the second frame 32; the indirect connection means that the flexible display screen 20 is connected to a structure, and then The structure connected with the flexible display screen 20 is connected to the first frame body 31 or the second frame body 32, so as to realize the connection between the flexible display screen 20 and the first frame body 31 or the second frame body 32.

In some embodiments of the present application, the first frame body 31 and the second frame body 32 are rigidly and fixedly connected to the shaft assembly 40. The rigid fixed connection means that when an acting force is applied to the first frame body 31 and the second frame body 32, the distance between the first frame body 31 and the second frame body 32 will not change. That is, the first frame 31 and the second frame 32 are restricted from moving away from or close to the rotating shaft assembly 40.

The seal ring is used to seal a gap between the support members (the first support member 11 and the second support member 12) and the ridge 33, and the back shell (the first back shell 71 and the second back member). The gap between the case 72) and the convex strip 33 prevents external impurities from entering the interior of the flexible display terminal 100 through the gap, so as to achieve a dustproof effect of the flexible display terminal 100.

According to the flexible display terminal 100 provided by the present invention, the flexible display screen 20 can be folded or flattened, so that compared with the structural parts of the existing electronic devices, the form is more diversified and can meet more needs. In addition, during the bending process of the flexible display terminal 100, due to a radius difference in the thickness direction of the flexible display terminal 100, the flexible display screen 20 located on the upper side will be stretched and easily damaged. In order to prevent the flexible display screen 20 from being stretched, the present invention designs the first support member 11 and the second support member 12 that are relatively movable, and fixes both ends of the flexible display screen 20 to the flexible display screen 20 respectively. The first support member 11 and the second support member 12 are used to offset the problem that the flexible display screen is stretched due to bending by the relative movement of the first support member 11 and the second support member 12. That is, during the bending process, the first support member 11 and the second support member 12 are moved toward each other, so that the length of the flexible display screen is kept constant, and the flexible display screen 20 is prevented from being stretched. Alternatively, in another embodiment, a sliding sheet 50 is further provided between the first support member 11 and the flexible display screen 20 so as to be relatively movable with respect to the first support member 11, and the flexible display screen 20 is Both ends are fixed to the sliding sheet 50 and the second support member 12, respectively, while the first support member 11 and the second support member 12 are used to slide relative to each other, the first support sheet 11 and the slide are used. The relative sliding between the sheets 50 can further avoid or reduce the damage caused by pulling or squeezing the flexible display screen 100 during the bending and unfolding process. In other words, this embodiment employs a dual mechanism to prevent the flexible display screen 20 from being stretched, one of which is the first support member 11 and the second support member 12 that are relatively movable, and the other is the relatively movable slide sheet 50 and First support sheet 11. The dual mechanism can effectively prevent or reduce the flexible display screen 20 from being stretched, thereby ensuring the normal operation of the flexible display terminal 100. However, it can be understood that any one of the two mechanisms can reduce the stretching of the flexible display screen 20, that is, any one of the mechanisms can be used alone, but the effect of using both of them is better. Further, when the flexible display terminal 100 is bent or flattened, the sliding sheet 50, the first supporting sheet 11 and the first back shell 71 can all move relative to the first frame 31, and the second Both the support sheet 12 and the second back shell 72 can move relative to the second frame body 32. When an external force acts on the first frame body 31 and / or the second frame body 32, the external force will not directly Acts on the first support member 11 (or the sliding sheet 50) and the second support member 12, so that no external force is transmitted to the flexible display screen 20, and the flexible display screen 20 is prevented from being damaged by arching. Specifically, the first frame body 31 and the second frame body 32 are both fixed to the rotating shaft assembly 40.
