Please refer to Figures 12 and 13 again. Each of the elastic members 3 is a torsion spring, including a first end 31 and a second end 32. The elastic members 3 are accommodated in the hollow portion 113. The first end 31 is fixed on the fixed part 1123 of the first shell 11 of the main unit 1, and the second end 32 is fixed on the sliding member 262 of the movable plate 26 of the movable unit 2, so The elastic member 3 is used to switch the movable unit 2 between the retracted state and the extended state. As shown in Figure 12, when the movable unit 2 is in the retracted state, the elastic member 3 tends to make the movable unit 2 switch between the retracted state and the extended state. The movable unit 2 remains in the retracted state. However, when you want to convert it to the extended state, an external force needs to be provided to push the movable unit 2 and overcome the elastic force provided by the elastic member 3 to make it escape from the retracted state. , and gradually move away from the main unit 1. After the movable unit 2 moves a specific distance relative to the main unit 1, the elastic member 3 will provide the elastic force to make the movable unit 2 reach the extended state, and make the movable unit 2 tends to remain in this extended state as shown in Figure 13 . Furthermore, when switching between the retracted state and the extended state, the first end 31 is disposed on the fixed part 1123 so that it is relatively immobile, and the second end 32 is disposed on the sliding member 262. In the retracted state shown in Figure 12, the second end 32 is relatively located on the side (ie, the right side) of the first end 31 away from the pivot 22, and tends to push the sliding member 262 away from the pivot 22, so it tends to Maintaining the retracted state, and in the extended state shown in FIG. 13 , the second end 32 is relatively located on the side (ie, the left side) of the first end 31 close to the pivot 22 and tends to move the sliding member 262 is pushed towards the pivot 22 and therefore tends to remain in this extended position. In other embodiments, each of the elastic members 3 can be a through-point snake spring, which can also produce the same effect.

Please refer to Figure 14 and Figure 15 together. The flexible display screen 4 includes a first end 41, a second end 42, a display area 43, a first retracted area 44 and a second retracted area 45. . Wherein, the first end 41 is provided on the first support member 12, the flexible display screen 4 covers the first support surface 121 and turns around the pivot axis 22, and turns again around the steering axis 25, the The second end 42 is fixed on the locking portion 1125 of the first shell 11 , so the flexible display screen 4 presents a roughly Z-shaped mirror cross section (from the other side of Figure 14, it is Z-shaped cross-section). Specifically, the display area 43 is between the first end 41 of the flexible display screen 4 and the pivot 22 , and the first retracted area 44 is between the pivot 22 and the steering axis 25 . The second retracted area 45 is between the steering shaft 25 and the second end 42 of the flexible display screen 4 . When the movable unit 2 is converted from the retracted state (Fig. 14) to the extended state (Fig. 15) relative to the main unit 1, the flexible display screen 4 will undergo dynamic changes, but the first retracted state The area of the area 44 remains unchanged, while the area of the display area 43 gradually becomes larger, and the area of the second retracted area 45 gradually becomes smaller (roughly the increased area of the display area 43 is equal to the reduced area of the second retracted area 45 area), conversely, when the movable unit 2 is converted from an extended state (Fig. 15) to a retracted state (Fig. 14) relative to the main body unit 1, the area of the first retracted area 44 remains unchanged, and the area of the first retracted area 44 remains unchanged. The area of the display area 43 gradually becomes smaller, and the area of the second retracted area 45 gradually becomes larger.

That is to say, in the extended state, the display area 43 is supported by the first supporting surface 121 and the second supporting surface 241 and is partially wrapped around the pivot 22 . In the retracted state, the display area 43 43 is supported by the first supporting surface 121 and partially wound around the pivot 22.

Specifically, as shown in Figures 1, 8, 10, 12, and 14, when the movable unit 2 is in the retracted state, the pivot 22 and the first shell member 11 are closest to each other, and the second support member 24 In its lowered position, it is accommodated in the accommodating space 13 and partially overlaps the first support member 12. At this time, the first support surface 121 and the second support surface 241 are not coplanar. The flexible display screen 4 is mainly supported by the first supporting surface 121 . In addition, when the second support member 24 is in its lowered position, the moving guide 244 is located in the first positioning section 11211, and the compression spring 27 is compressed by the second support member 24, and the flexible display screen The area of the display area 43 of 4 is the smallest, and the area of the second retracted area 45 is the largest. Furthermore, as shown in Figure 12, when the movable unit 2 is in the retracted state, the sliding protrusion 2621 is located at the first resisting end 1141 of the chute portion 114, and the elastic member 3 is compressed and accommodated. placed in the hollow part 113 .

When wanting to convert the movable unit 2 from the retracted state to the extended state as shown in Figures 2, 9, 11, 13, and 15 to increase the display area of the flexible display screen 4, the user can An external force is provided to the movable unit 2 so that the movable unit 2 escapes from the retracted state. At this time, the elastic force provided by the compressed elastic member 3 allows the movable unit 2 to gradually move along the telescopic axis A1, where , when the movable unit 2 moves in the direction away from the first housing 11 along the telescopic axis A1, the moving guide 244 of the second support member 24 moves on the translation section 11212, and the steering shaft 25 gradually Far away from the first end 41 of the flexible display screen 4 and at the same time close to the second end 42 of the flexible display screen 4, the area of the display area 43 gradually becomes larger, and the second retracted area 45 gradually becomes smaller. At the same time, the area of the first retracted area 44 remains unchanged, and the telescopic portion 52 of the constant force spring 5 is stretched when the steering shaft 25 gradually moves away, and the tensile force provided by it is The flexible display screen 4 can be tightened, and the sliding protrusion 2621 slides in the sliding groove portion 114 from the first resisting end 1141 to the second resisting end 1142 .

Then, when the moving guide 244 moves from the translation section 11212 to the lifting section and then moves to the second positioning concave section 11211, the second support member 24 is lifted, and at the same time, the compression spring 27 provides an elastic The force is applied to the second support member 24, and the second support member 24 slightly pivots relative to the pivot 22, so that the second support member 24 is aligned with the first support member 12. As shown in Figure 15, the second support member 24 is The two supporting surfaces 241 are coplanar with the first supporting surface 121 and jointly support the display area 43 of the flexible display screen 4. At this time, the area of the display area 43 of the flexible display screen 4 is the largest. The second adduction area 45 has the smallest area. Furthermore, as shown in FIG. 13 , when the movable unit 2 is in the extended state, the sliding protrusion 2621 is located at the second resisting end 1142 of the chute portion 114 .

In addition, because the pivot 22 is a damping axis, when the movable unit 2 slides back and forth relative to the main unit 1, the pivot 22 provides the damping force to prevent the movable unit 2 from moving too fast relative to the main unit 1. Damage to components, and for users, it can provide a harmonious and smooth operating feel to improve the quality and value of the product. However, the pivot 22 is not limited to a damping axis, and may also be a rotating axis that generally has no damping effect. In addition, if the pivot 22 is a general rotating shaft without a damping effect, a damping rod (not shown) can be provided along the telescopic axis A1 to contact between the first shell 11 and the frame 21 . Provides damping effect.
