Please refer to the partially enlarged view shown in FIG. 5 and the schematic three-dimensional view shown in FIG. 7 . The second support member 24 has a main plate 240 , two wing plates 241 , two abutment parts 242 , and three pivot parts. 243. A moving guide 244, a second supporting surface 245, a second inner surface 246, a second inclined surface 247, a second inner acute angle 248, and a second inner obtuse angle 249. The second supporting member 24 passes through all The hook part 23 is hung on the pivot 22 and can pivot relative to the hook part 23, and can pivot between a lowering position (Fig. 8) and an alignment position (Fig. 9).

The wing plates 241 are respectively provided on both sides of the main board 240 and extend substantially perpendicularly to the main board 240. They are fixed on the frame 21 and each has a guide groove 2411. The butt portions 242 respectively correspond to The wing plates 241 are arranged on one side adjacent to each other, extend substantially parallel to the main plate 240 , and are supported by the compression springs 27 . The second support members 24 respectively correspond to the pivot portions 243 through the pivot portions 243 . The hook piece 23 is pivoted.

Specifically, the moving guide 244 is disposed on the wing plate 241 corresponding to the displacement guide plate body 1121 on the first shell 11, and resists the displacement guide plate body 1121; as shown in Figure 10, the moving guide The component 244 is a roller as an example. When the movable unit 2 is in the retracted state, the moving guide 244 is positioned at the first positioning section 11211, so that the second support member 24 is positioned at the lowering position; When the movable unit 2 leaves the retracted state, the moving guide 244 slides along the translation section 11212; when the movable unit 2 leaves the retracted state and switches to the extended state, the moving guide 244 slides along the translation section 11212. The section 11212 slides to the lifting section 11213 to lift the second support member 24 until the moving guide 244 is positioned to the second positioning concave section 11214, and the second support member 24 is converted to the alignment shown in Figure 11 position, the movable unit 2 is in the extended state.

A second internal obtuse angle 249 is formed between the second inclined surfaces 247 , and a second acute internal angle 248 is formed between the second inner surface 246 and the second inclined surface 247 . The first internal acute angle 124 and the second internal obtuse angle 249 are substantially complementary, and the first internal obtuse angle 125 and the second internal acute angle 248 are substantially complementary. Thereby, the transition of the second support member 24 between the lowering position and the alignment position can be smoother.

The steering shaft 25 is connected to the frame 21 through its two ends and is received in the accommodation space 13 . The movable plate 26 partially covers the first shell 11 .

Specifically, the movable plate 26 has a back cover 261 and a sliding member 262. The sliding member 262 further has two sliding protrusions 2621, which respectively correspond to and interact with the chute portion 114 of the first shell 11. In cooperation, when the movable unit 2 moves relative to the main unit 1 , the sliding protrusions 2621 respectively move along the slide groove portion 114 . As shown in Figure 12, when the mobile unit 2 is in the retracted state, the sliding protrusions 2621 are respectively located at the first abutting end 1141 of the chute portion 114. As shown in Figure 13, when the When the mobile unit 2 switches to the extended state, the sliding protrusions 2621 are respectively located at the second abutting ends 1142 of the chute portion 114 .

The compression spring 27 is disposed on the frame 21 against the backing plate 242 of the second supporting member 24, and constantly provides a supporting force on the second supporting member 24, as shown in Figure 10. In the retracted state, the compression spring 27 makes the second support member 24 tend to approach the first support member 12 , and in the extended state as shown in FIG. 11 , the compression spring 27 supports the second support member 24 . The support member 24 (that is, the compression spring 27 is always inclined to provide upward support force) is coplanar with the first support member 12 and jointly supports the flexible display screen 4 (Fig. 15).

Referring to Figures 10 and 11, the guide members 28 are disposed on the movable plate 26, and each has a guide post 281. The guide post 281 corresponds to the guide groove 2411 and can be positioned in the guide groove 2411. Slide in the groove 2411, as shown in Figure 10, when the second support member 24 is in the lowering position, the guide post 281 is at the first end 24111 of the guide groove 2411, and as shown in Figure 11 The second support member 24 is in the aligned position, and the guide post 281 is at the second end 24112 in the guide groove 2411 to limit the movement path of the second support member 24 when switching between the lowering position and the aligned position. And ensure that the second support plate 24 will not exceed the alignment position due to the upward support force provided by the compression spring 27 .

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 and is relatively immobile, while the second end 32 is disposed on the sliding member 262, and In the retracted state shown in FIG. 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 . Therefore, tend to remain in the retracted state, and in the extended state shown in Figure 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 be The slider 262 pushes against 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.

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. In the retracted state or the extended state, the first retracted area 44 and the second retracted area 45 are always stored in the container. Set in space 13.

The winding portion 51 is provided on the base 1111 of the first shell 11, and the telescopic portion The portion 52 is fixed on the frame 21 and constantly provides the pulling force of the frame 21 toward the first shell 11 along the telescopic axis A1, so that the steering shaft 25 provided on the frame 21 constantly tightens the removable Flexible display screen 4.

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.
