It can be understood that referring to FIGS. 1, 2 and 6, when only the flat portion 211 of the flexible display 21 is exposed from the housing assembly 10, the display area of the electronic device 100 is relatively small. At this time, the first housing 11 and the second housing 11 The two shells 12 are fitted together to form a small-volume shell assembly 10, and the electronic device 100 is in a narrow screen mode. In this case, the second shell 12 may be partially housed in the installation cavity 1122 of the first shell 11 or may be completely housed in the installation cavity 1122.

Referring to FIGS. 3, 4 and 7, when the second shell 12 slides to the side away from the first shell 11 relative to the first shell 11, the second shell 12 body drives the expansion portion 212 to at least partially expand to the shell The component 10 is used to adjust the display area of the electronic device 100.

When the second housing 12 slides to the extreme position in the direction away from the first housing 11, the exposed area of the expansion portion 212 is the largest, and the display area is also the largest (see FIG. 4). At this time, the electronic device 100 is in a widescreen mode. It is understandable that, in the embodiment of the present application, in the widescreen mode, the second housing 12 can slide relative to the first housing 11 to the side close to the first housing 11, thereby driving the expansion portion 212 to be at least partially retracted to In the housing assembly 10, the display area of the electronic device 100 is reduced, that is, it moves from the state shown in FIG. 4 to the state shown in FIG. 2. That is to say, in the embodiment of the present application, the second shell 12 can slide relative to the first shell 11 to drive the expansion part 212 to at least partially expand out of the shell assembly 10 or retract into the shell assembly 10, thereby adjusting the electronics For the display area of the device 100, the electronic device 100 can switch between the narrow screen mode and the wide screen mode.

In this way, the support sheet 221 can be arranged to support the expansion part 212 without preventing the expansion part 212 from being bent and curled. In addition, the supporting sheet 221 can make the force-receiving body 1121 of the expansion part 212 be the supporting sheet 221 when the expansion part 212 is bent or curled, thereby increasing the life of the flexible display screen 21.

It should be noted that, in the embodiment of the present application, the supporting sheet 221 has a bending characteristic in the sliding direction of the second housing 12 (ie, the lateral direction of the electronic device 100), and has a rigid characteristic in the longitudinal direction of the electronic device 100. In other words, in the embodiment of the present application, the supporting sheet 221 can be bent along the lateral direction of the electronic device 100 but cannot be bent along the longitudinal direction. Specifically, the supporting sheet 221 may be a steel sheet.

It should be pointed out that in the description of this application, it should be understood that the orientation or positional relationship indicated by the terms "horizontal" and "longitudinal" is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the application. And to simplify the description, rather than indicating or implying that the pointed device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present application.

In addition, referring to FIGS. 6 and 7, in this embodiment, the surface of the top plate 1123 of the fixing bracket 112 connected to the flat portion 211 is flush with the surface of the supporting member 22 connected to the expanded portion 212, that is, the upper surface of the supporting member 22 is flush with The upper surface of the top plate 1123 is flush.

In this way, when the expansion part 212 is driven by the second shell 12 to be at least partially exposed from the housing assembly 10, the upper surface of the support member 22 is flush with the upper surface of the top plate 1123 so that the flat part 211 and the exposed expansion part 212 are different. There will be a significant height difference, so that the flexible display screen assembly 20 is relatively flat, thereby ensuring the flatness of the flexible display screen assembly 20, which can improve the user's operating experience and the aesthetic appearance of the electronic device 100.

It should be noted that in this article, "flat" can be understood as the two surfaces have the same height, and there is no height difference between the two, or it can be understood that the height difference between the two is within the range of manufacturing error and assembly error. .

It can be understood that, in the embodiment of the present application, when the second shell 12 slides relative to the first shell 11, the support plate 1222 slides in the sliding groove 1124. The support plate 1222 can support the expansion part 212 expanded to the outside of the housing assembly 10 so that the expansion part 212 does not appear obvious depression when it is pressed.

The flexible display assembly 20.

In this way, when the expansion part 212 is driven by the second shell 12 to expand out of the housing assembly 10 or retracted into the housing assembly 10, the tensioning structure 90 can tension the flexible display screen assembly 20, so that the expansion part The 212 will not be arched and wrinkled to ensure that the expansion part 212 can be smoothly expanded or retracted.

Specifically, referring to FIGS. 6 and 7, the tensioning structure 90 includes a first tensioning member 91 and a second tensioning member 92. The first tensioning member 91 is fixedly connected to the sliding bracket 122 of the second housing 12 and can follow the first tensioning member 91. The second shell 12 moves relative to the first shell 11. The second tensioning member 92 is fixedly arranged on the fixing bracket 112 of the first shell 11, and the first tensioning member 91 and the second tensioning member 92 are sequentially arranged around the middle part of the connecting member 23.

When the second shell 12 is relatively far away from the first shell 11, the first tension member 91 follows the movement of the second shell 12, the second tension member 92 is fixed, and the first tension member 91 gradually releases the connecting member 23, thereby gradually Release the expansion part 212, the expansion part 212 is gradually expanded to the outside of the housing assembly 10 under the action of the second shell 12, the movement distance of the first tension member 91 is the same as the movement stroke of the expansion part 212, in this way, the expansion part 212 is gradually expanded During the process to the outside of the housing assembly 10, the first tensioning member 91 can tension the connecting member 23, so as to realize the tensioning of the flexible display screen assembly 20.

When the second shell 12 is relatively close to the first shell 11, the first tension member 91 follows the movement of the second shell 12, the second tension member 92 is also fixed, the second shell 12 gradually releases the expansion part 212, the first tension The tightening member 91 drives the connecting member 23 to move to the side where the first housing 11 is located, thereby driving the expansion portion 212 to gradually retract into the housing assembly 10. In this process, the distance moved by the first tensioning member 91 and the expansion portion 212 are The movement stroke of is also the same. In this way, when the expansion part 212 is retracted and expanded to the housing assembly 10, the first tensioning member 91 can tension the connecting member 23, thereby realizing the tensioning of the flexible display screen assembly 20. It can be understood that during the assembling process of the electronic device 100, one end of the connecting member 23 can be sequentially wound around the first tensioning member 91 and the second tensioning member 92 and then fixedly connected to the first housing 11. It is necessary to ensure that the flexible display screen assembly 20 is in a tensioned state.

In the illustrated embodiment, the first tension member 91 includes a pulley, the pulley is rotatably arranged on the second shell 12, and the middle part of the connecting member 23 is arranged around the pulley. In this way, when the second shell 12 drives the expansion part 212 and the connecting piece 23 to move, the pulley rolls accordingly, and there is rolling friction between the two, and the friction is relatively small. Compared with directly fixing the first tensioning piece 91 on the second In the manner of the shell 12, the rotation can prevent the friction between the connecting member 23 and the first tensioning member 91 from being too large, which may cause the connecting member 23 to wear and even get stuck. Of course, in some embodiments, the first tensioning member 91 can also be directly fixed to the first shell 11, and it is only necessary to make the surface of the first tensioning member 91 as smooth as possible during the manufacturing process without contacting the connecting member 23. It is enough to generate a larger friction force.

In addition, it can be understood that, in some embodiments, the second tensioning member 92 can also be a pulley that is rotatably arranged on the first shell 11. In this case, the first tensioning member 91 is a movable pulley, and the second tensioning member 91 is a movable pulley. The tension member 92 is a fixed pulley.

The movement of, that does not affect the expansion of the expansion part 212. In addition, since the support sheet 221 of the support member of the flexible display screen assembly 20 has rigidity, the support sheet 221 can also restrict the movement of the expansion part 212 of the flexible display screen assembly 20 in the thickness direction to a certain extent to prevent the expansion part 212 from moving in the thickness direction. Wrinkles or arches appear during the movement. In this way, the support piece 221 and the pressing member 13 cooperate with each other to restrict the movement of the expansion part 212 more effectively.
