Specifically, when the driving assembly 22 controls the rotation of the reel 21 so that the flexible display device 30 gradually extends out of the housing 10, the elastic support assembly 32 drives the flexible display device 30 from the winding The state switches to the straight state.

本申请的弹性支撑组件32具有多种实施方式，包括但不限于以下实施例：The elastic support assembly 32 of the present application has various implementations, including but not limited to the following embodiments:

一种实施例中，如图7所示，所述弹性支撑组件32包括两个弹性钢片321和支撑钢片322，两个所述弹性钢片321分别位于所述支撑钢片322的平行于长度方向的两个相对的侧边。两个弹性钢片321与支撑钢片322均设于柔性屏31的背面，且支撑钢片322与位于其两侧边的弹性钢片321连接，以保证弹性支撑组件32的整体强度。本实施例中，弹性钢片321和支撑钢片322具有卷绕状态和平直状态，当处于卷绕状态的弹性钢片321和支撑钢片322不受外力时，具有恢复自身弹性形变的弹性力，以使弹性钢片321和支撑钢片322从卷绕状态切换至平直状态，从而所述柔性屏31随着弹性钢片321和支撑钢片322从卷绕状态切换至平直状态，以使柔性屏31展平。弹性钢片321和支撑钢片322一方面能使柔性屏31展平，保持平直状态，另一方面，弹性钢片321和支撑钢片322还起着在柔性屏31展平时支撑柔性屏31，以使用户在对柔性屏31进行触屏操作时，柔性屏31不会发生下陷的问题。In an embodiment, as shown in FIG. 7, the elastic support assembly 32 includes two elastic steel sheets 321 and a support steel sheet 322, and the two elastic steel sheets 321 are respectively located parallel to the support steel sheet 322. Two opposite sides in the length direction. The two elastic steel sheets 321 and the supporting steel sheets 322 are both arranged on the back of the flexible screen 31, and the supporting steel sheets 322 are connected with the elastic steel sheets 321 on both sides thereof to ensure the overall strength of the elastic support assembly 32. In this embodiment, the elastic steel sheet 321 and the supporting steel sheet 322 have a rolled state and a straight state. When the elastic steel sheet 321 and the supporting steel sheet 322 in the rolled state are not subjected to external force, they have the elastic force to restore their own elastic deformation. , So that the elastic steel sheet 321 and the supporting steel sheet 322 are switched from the winding state to the flat state, so that the flexible screen 31 is switched from the winding state to the flat state along with the elastic steel sheet 321 and the supporting steel sheet 322. The flexible screen 31 is flattened. On the one hand, the elastic steel sheet 321 and the supporting steel sheet 322 can make the flexible screen 31 flatten and maintain a straight state. On the other hand, the elastic steel sheet 321 and the supporting steel sheet 322 also function to support the flexible screen 31 when the flexible screen 31 is flattened. , So that when the user performs a touch-screen operation on the flexible screen 31, the flexible screen 31 will not sag.

所述弹性支撑组件32处于卷绕状态时为形变状态，所述弹性支撑组件32处于平直状态时为自然状态。换言之，弹性钢片321和支撑钢片322处于卷绕状态时为形变状态，弹性钢片321和支撑钢片322处于平直状态时为自然状态，当弹性钢片321和支撑钢片322受到卷轴21的卷绕力时，弹性钢片321和支撑钢片322卷绕于卷轴21上，发生形变，当弹性钢片321和支撑钢片322不受卷轴21的卷绕力时，弹性钢片321和支撑钢片322从形变状态切换到自然状态，保持平直。The elastic support component 32 is in a deformed state when it is in a wound state, and it is in a natural state when the elastic support component 32 is in a straight state. In other words, the elastic steel sheet 321 and the supporting steel sheet 322 are in a deformed state when they are in the wound state, and the elastic steel sheet 321 and the supporting steel sheet 322 are in a natural state when the elastic steel sheet 321 and the supporting steel sheet 322 are in a straight state. 21, the elastic steel sheet 321 and the supporting steel sheet 322 are wound on the reel 21 and deformed. When the elastic steel sheet 321 and the supporting steel sheet 322 are not subjected to the winding force of the reel 21, the elastic steel sheet 321 And the supporting steel sheet 322 is switched from the deformed state to the natural state and remains straight.

可以理解的，如图7所示，弹性钢片321包括钢片主体3211及设于钢片主体3211两端的连接端3212，钢片主体3211的宽度方向的横截面为圆弧形，连接端3212的宽度方向的横截面为平面。当弹性钢片321卷绕时，圆弧形的钢片主体3211发生形变，当弹性钢片321不受力的情况下，圆弧形的钢片主体3211回复到原来的平直状态及圆弧形状，从而弹性钢片321具有更大的弹性回复力，以使弹性钢片321具有足够的支撑力以支撑柔性屏31及保持柔性屏31保持平直，提高用户体验。连接端3212的宽度方向的横截面为平面，从而更便于与卷轴21连接。It can be understood that, as shown in FIG. 7, the elastic steel sheet 321 includes a steel sheet main body 3211 and connecting ends 3212 provided at both ends of the steel sheet main body 3211. The widthwise cross section of the steel sheet main body 3211 is arc-shaped, and the connecting ends 3212 The cross-section in the width direction is a plane. When the elastic steel sheet 321 is wound, the arc-shaped steel sheet main body 3211 is deformed. When the elastic steel sheet 321 is not stressed, the arc-shaped steel sheet main body 3211 returns to its original straight state and arc. Therefore, the elastic steel sheet 321 has a greater elastic restoring force, so that the elastic steel sheet 321 has sufficient supporting force to support the flexible screen 31 and keep the flexible screen 31 straight, thereby improving user experience. The cross section in the width direction of the connecting end 3212 is a plane, so that it is more convenient to connect with the reel 21.

The fixing portion 332 is connected to the upper fixing portion 331 and the lower fixing portion 332. The upper fixing portion 331 is located on the display surface 311 of the flexible screen 31, and the lower fixing portion 332 is located on the side of the elastic support assembly 32 facing away from the flexible screen 31. The lower fixing portion 332 is fixed so as to fix the flexible screen 31 and the elastic support assembly 32 to prevent the flexible screen 31 from being supplied to the elastic support assembly 32 when the flexible screen 31 and the elastic support assembly 32 are rolled up. Specifically, there are a plurality of fixing portions 33, and the plurality of fixing portions 33 are arranged at intervals on opposite sides of the flexible screen 31 and the elastic support assembly 32 in the longitudinal direction. Specifically, the upper fixing portion 331 is located at the edge of the display surface 311 of the flexible screen 31, and the lower fixing portion 332 is connected and fixed with the elastic steel sheet 321 and the supporting steel sheet 322. Optionally, the fixing portion 33 and the supporting steel sheet 322 are integrally formed to increase the connection strength between the fixing portion 33 and the supporting steel sheet 322. In other words, a plurality of spaced fixing portions 33 extend on both sides of the supporting steel sheet 322 in the longitudinal direction, and the lower fixing portion 332 of the fixing portion 33 is provided between the elastic steel sheet 321 and the flexible screen 31 and faces the display surface 311 of the flexible screen 31 The upper fixing portion 331 is bent to be fixed on the edge of the display surface 311. The surface of the lower fixing portion 332 facing the elastic steel sheet 321 is welded and fixed to the elastic steel sheet 321. In other embodiments, the surface of the lower fixing portion 332 facing the elastic steel sheet 321 is bonded and fixed to the elastic steel sheet 321 or fixed by other means.

进一步的，如图7所示，所述支撑钢片322开设有间隔设置的多个通孔3221，多个通孔3221整齐排列于支撑钢片322上，所述弹性支撑组件32还包括弹性胶体(图未示)，弹性胶体填充于通孔3221中，所述弹性胶体将柔性屏31粘接于所述支撑钢片322，所述弹性胶体具有弹性行程量，从而允许所述柔 性屏31相对于所述支撑钢片322移动。换言之，柔性屏31和支撑钢片322在卷绕于卷轴21上时，会有微小的位移差，弹性胶体具有弹性行程量，从而在卷绕时柔性屏31和支撑钢片322之间可相对移动，从而避免柔性屏31和支撑钢片322之间不能相对移动而导致的柔性屏31和支撑钢片322在卷绕于卷轴21时会拱起而不平整，可能损坏柔性屏31的情况。同时，弹性胶体也避免柔性屏31和支撑钢片322卷绕时贴太紧而使柔性屏31受到损害。Further, as shown in FIG. 7, the supporting steel sheet 322 is provided with a plurality of through holes 3221 arranged at intervals, and the plurality of through holes 3221 are neatly arranged on the supporting steel sheet 322, and the elastic support component 32 further includes an elastic gel.

Move on the supporting steel sheet 322. In other words, when the flexible screen 31 and the supporting steel sheet 322 are wound on the reel 21, there will be a slight displacement difference, and the elastic gel has an elastic stroke, so that the flexible screen 31 and the supporting steel sheet 322 can face each other during winding. Therefore, the flexible screen 31 and the supporting steel sheet 322 cannot be moved relative to each other and the flexible screen 31 and the supporting steel sheet 322 will arch and become uneven when they are wound on the reel 21, which may damage the flexible screen 31. At the same time, the elastic gel also prevents the flexible screen 31 and the supporting steel sheet 322 from being too tightly attached when they are wound, which may damage the flexible screen 31.

The elastic support When the component 32 is in the wound state and is not subject to external force, the support rod 323 is restored to the flat state by the restoring force of the elastic member 324, so that the flexible screen 31 switches from the winding state to the flat state along with the support rod 323 . At the same time, the support rod 323 also plays a role of supporting the flexible screen 31, so that when the user performs a touch screen operation on the flexible screen 31, the flexible screen 31 will not sag. In this embodiment, the elastic member 324 is not provided between the two support rods 323 at the winding end 301, so that the elastic support assembly 32 is well fitted with the reel 21 when it is wound on the reel 21.
