It should be noted that in the description of the present invention, it is to be understood that the terms "thickness", "upper", "lower", "inner" and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, which are only for convenience of description and simplification of description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

In this embodiment, the flexible display 21 includes a flat portion 211 and an expanded portion 212. The flat portion 211 is exposed outside the housing assembly 10. Specifically, the flat portion 211 is disposed above the fixed bracket 112 and is at least partially fixedly connected to the top plate 1123 of the fixed bracket 112. The expansion portion 212 can be hidden in the housing assembly 10, one end of the expansion portion 212 is connected to the flat portion 211, the other end can be connected to a take-up device such as a reel, the middle portion of the expansion portion 212 is wound around the guide shaft 40 provided on the sliding bracket 122, and the expansion portion 212 is at least partially received in the receiving chamber 1213 of the second case 12.

When the second shell 12 slides relative to the first shell 11 away from the first shell 11, the second shell 12 may drive the expansion portion 212 to at least partially expand out of the housing assembly, so as to form a display portion of the electronic device 100 together with the expansion portion 211. It will be appreciated that in an embodiment of the invention, the extension 212 may be gradually released by a take-up device such as a reel during deployment of the extension 212 out of the housing assembly 10 by the second shell 12. In the process of gradually retracting the extension portion 212 into the housing assembly 10, a take-up device such as a reel may gradually take up the extension portion 212. It is understood that the winding device may wind the expansion portion 212 directly or connect the expansion portion 212 through other elements, such as a connecting member such as a belt to connect the expansion portion 212, and the expansion portion 212 may be released and wound by winding the releasable belt.

In this embodiment, the flat portion 211 and the top plate 1123 may be fixed by a double-sided tape or an optical tape. It is understood that in other embodiments, other fixing means may be used, for example, magnetic attraction may be used for fixing, and in such embodiments, a magnetic element may be attached to the back of the flat portion 211, and the top plate 1123 may be made of a magnetic material, and the two are magnetically attracted together, and the specific arrangement is not limited herein.

It can be understood that, referring to fig. 1, fig. 2 and fig. 6, when only the flat portion 211 of the flexible display screen 21 is exposed from the housing assembly 10, the display area of the electronic device 100 is small, and at this time, the first shell 11 and the second shell 12 are combined together to form a smaller housing assembly 10, and the electronic device 100 is in the narrow screen mode. In this case, second housing 12 may be partially housed in mounting cavity 1122 of first housing 11, or may be entirely housed in mounting cavity 1122.

Referring to fig. 3, 4 and 7, when the second shell 12 slides relative to the first shell 11 to a side away from the first shell 11, the second shell 12 drives the expansion portion 212 to at least partially expand to the outside of the housing assembly 10 to adjust the display area of the electronic device 100, so that the exposed expansion portion 212 and the exposed expansion portion 211 jointly form a display portion of the electronic device 100, and the display area is larger. When the second housing 12 is slid to the limit position in the direction away from the first housing 11, the exposed area of the expanded portion 212 is maximized and the display area is also maximized (see fig. 4), and at this time, the electronic apparatus 100 is in the wide screen mode. It can be understood that, in the embodiment of the present invention, in the wide screen mode, the second shell 12 can slide relative to the first shell 11 to a side close to the first shell 11, so as to drive the extension portion 212 to be at least partially retracted into the housing assembly 10, thereby reducing the display area of the electronic device 100, i.e. moving from the state shown in fig. 4 to the state shown in fig. 2. That is, in the embodiment of the present invention, the second shell 12 can slide relative to the first shell 11 to drive the extension portion 212 to at least partially expand out of the housing assembly 10 or retract into the housing assembly 10, so as to adjust the display area of the electronic device 100, and the electronic device 100 can be switched between the narrow-screen mode and the wide-screen mode.

In addition, in the illustrated embodiment, the second shell 12 carries the extension portion 212 to be partially exposed from the housing assembly 10, that is, when the electronic device 100 is in the wide screen mode, the extension portion 212 is only partially exposed from the housing assembly 10. It is understood that in some embodiments, the extension portion 212 may also be entirely exposed from the housing assembly 10 when the electronic device 100 is in the wide screen mode, and is not limited herein.

Referring to fig. 6 to 7, in the present embodiment, the supporting member 22 is stacked below the expanding portion 212, and the supporting member 22 at least partially covers the expanding portion 212. The support 22 serves to support the extension portion 212, and the support 22 moves following the extension portion 212 to support the extension portion 212 when the extension portion 212 moves.

The support 22 includes a plurality of support pieces 221 arranged at intervals, and the support pieces 221 can be bent in the sliding direction of the second housing 12 such that the middle portion of the expanded portion 212 is wound around the sliding bracket 122.

As such, the support piece 221 may be provided to support the expansion portion 212 without preventing the expansion portion 212 from being bent and curled. Moreover, the supporting piece 221 enables the force-bearing body 1121 of the expansion portion 212 to be the supporting piece 221 when the expansion portion is bent or curled, so as to improve the service life of the flexible display 21.

In addition, referring to fig. 6 and 7, in the present 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.

Thus, when the extension portion 212 is driven by the second shell 12 to be at least partially exposed from the housing assembly 10, the upper surface of the supporting member 22 is flush with the upper surface of the top plate 1123, so that there is no significant height difference between the flat portion 211 and the exposed extension portion 212, and the flexible display screen assembly 20 is relatively flat, and the flatness of the flexible display screen assembly 20 is ensured, which not only improves the operation experience of the user, but also improves the aesthetic appearance of the electronic device 100.

It should be noted that "flush" herein may be understood as the height of both surfaces being the same, there being no height difference between the two surfaces, or the height difference between the two surfaces being within the manufacturing error and the assembling error.

It is understood that in the embodiment of the present invention, the support plate 1222 slides within the sliding groove 1124 when the second housing 12 slides with respect to the first housing 11. The support plate 1222 may support the extension portion 212 expanded out of the housing assembly 10 such that the extension portion 212 does not appear to be depressed significantly when pressed.

Referring to fig. 5 to 7, in the present embodiment, the guide shaft 30 is disposed in the mounting portion 1223 of the second housing 12 and is rotatably connected to the second housing 12, that is, the guide shaft 30 can rotate in the mounting portion 1223. The intermediate portion of the expanded portion 212 is wound around the guide shaft 30.

In this manner, the guide shaft 30 may guide when the expansion portion 212 moves, so that the expansion portion 212 can be smoothly unfolded to be exposed from the housing assembly 10.

In addition, the presence of the guide shaft 30 may maintain the form of the extension portion 212, thereby preventing the extension portion 212 from being largely deformed during movement to reduce the life of the flexible display 21.

Specifically, in the present embodiment, the guide shaft 30 may make the extension portion 212 substantially U-shaped, so that the extension portions 212 on both sides of the guide shaft 30 can be kept flat to improve the life of the flexible display 21. It is understood that in some embodiments, the electronic device 100 may not include the guide shaft 30, as long as the second shell 12 can move the extension portion 212 to expose the housing assembly 10.

Referring to fig. 8, in the present embodiment, the driving assembly 40 may be disposed in the first housing 11. The driving assembly 40 includes a power mechanism 41 and a transmission mechanism 42, the power mechanism 41 is disposed in the first housing 11, the transmission mechanism 41 is connected to the power mechanism 41 and the second housing 12, and the power mechanism 41 is configured to drive the second housing 12 to move relative to the first housing 11 through the transmission mechanism 42.

In a possible embodiment, the power mechanism 41 includes a motor 411 and a gear set 412, the transmission mechanism 42 includes a screw rod 421 and a moving member 422 sleeved on the screw rod 421, the screw rod 421 is in threaded connection with the moving member 422, the moving member 422 is fixedly connected with the sliding support 122 of the second shell 12, the gear set 412 is connected with a motor shaft of the motor 411 and the screw rod 421, for example, one gear of the gear set 412 may be fixedly connected with the screw rod 421 or a tooth portion is formed on the screw rod 421, and the motor 411 is configured to drive the screw rod 421 to rotate through the gear set 412, so as to drive the moving member 422 to move on the screw rod 421, and further drive the second shell 12 to move relative to the.

It is understood that, in other embodiments, the transmission mechanism 42 may also be a rack portion fixedly disposed on the second housing 12, the gear set of the power mechanism 41 is engaged with the rack portion, and the motor 411 drives the gear set 412 to rotate, so as to drive the second housing 12 to move relative to the first housing 11 through the rack portion. In some embodiments, the power mechanism 41 may also drive the screw 421 by other methods, for example, a combination of belt transmission and gear transmission is used to drive the screw 421, or a combination of worm and gear transmission is used to drive the screw 421, which is not limited herein.

Furthermore, it can be understood that, in some embodiments, the motor 411 and the gear set 412 of the power mechanism 41 may also be disposed on the second housing 12, the rack portion may be disposed on the first housing 11, and the power mechanism 41 may simultaneously move along with the second housing 12 while the power mechanism 41 drives the second housing 12 to move relative to the first housing 11, and the specific arrangement is not limited herein, and only needs to be able to drive the second housing 12 to move relative to the first housing 11.

Referring to fig. 5 to fig. 7, in the present embodiment, the electronic device 100 further includes a position detecting element 70, the position detecting element 70 is disposed in the housing assembly 10, and the position detecting element 70 is used for detecting a display area of the electronic device 100.

In this way, the movement of the second shell 12 can drive the extension portion 212 to at least partially extend out of the housing assembly 10 or retract into the housing assembly 10 to adjust the display area of the electronic device 100, and the electronic device 100 can detect the size of the display area through the position detection assembly 70, so that the electronic device 100 can realize any switching of different display areas.

Specifically, when a user needs to adjust the display area of the electronic device 100, the processor of the electronic device 100 disposed on the main board 60 receives the adjustment instruction, so as to send a driving instruction to the driving assembly 40 through the processor, and the driving assembly 40 drives the second shell 12 to move, so as to drive the expansion portion 212 to at least partially expand out of the housing assembly 10 or retract into the housing assembly 10, thereby adjusting the display area of the electronic device 100. The position detecting assembly 70 can detect the display area of the electronic device 100 in real time, and when the display area of the electronic device 100 reaches the area desired by the user, the position detecting assembly 70 feeds back an instruction to the processor of the electronic device 100, so as to turn off the driving assembly 40.

Referring to fig. 6 and 7, in one embodiment, the position detection assembly 70 includes a sensor 71 and a sensing member 72. The sensor 71 and the sensing member 72 are spaced apart, and the sensor 71 and the sensing member 72 cooperate to detect a display area of the electronic device 100.

In addition, in the present embodiment, the position detection assembly 70 further includes a circuit board 73, the sensor 71 is disposed on the circuit board 73, and the circuit board 73 is electrically connected to the main board 60. In this way, the sensor 71 may transmit the detection information to the processor on the main board 60 through the circuit board 73 so that the processor can control the operating state of the motor 411 of the driving assembly 40 according to the detection information.

Referring to fig. 7, in such an embodiment, the sensor 71 is disposed on the first housing 11, the sensing member 72 is disposed on the second housing 12, and the sensor 71 is used for detecting a distance between the sensor 71 and the sensing member 72, so as to detect a relative position between the second housing 12 and the first housing 11 to detect a display area of the electronic device 100.

The sensing member 72 may be fixedly mounted on the sliding bracket 122 of the second case 12, and specifically, the sensing member 72 may be disposed on a frame 1221 of the sliding bracket 122. When the second housing 12 moves relative to the first housing 11, the sensing member 72 moves along with the second housing 12, that is, the sensing member 72 moves relative to the sensor 71 and the first housing 12. In this case, the sensor 71 may detect a distance between itself and the sensing member 72, so as to detect a relative position between the second shell 12 and the first shell 11, that is, a moving stroke of the second shell 12 relative to the first shell 11, so as to detect an area where the second shell 12 drives the extension portion 212 to be extended out of the housing assembly 10 or retracted into the housing assembly 10, and thus detect a display area of the electronic device 100. It should be noted that, in this document, the "display area" refers to the area of the portion of the flexible display screen assembly 20 exposed outside the housing assembly 10 for display.

In some embodiments, the sensor 71 includes a hall sensor, and the sensing member 72 may include a magnetic member, such as a magnet, for sensing a magnetic field strength to detect a distance between the hall sensor and the magnetic member, thereby detecting a relative position of the second housing 12 and the first housing 11.

Thus, when the magnetic member moves along with the second housing 12, the distance between the hall sensors changes, so that the magnetic field strength sensed by the hall sensors 71 changes, and further the hall sensors can detect the distance between the magnetic member and the change of the magnetic field strength, and further detect the relative position between the second housing 12 and the first housing 11 to achieve the purpose of detecting the display area of the electronic device 100.

In some embodiments, the sensor 71 of the position detecting assembly 70 may also be disposed on the motor shaft of the motor 411 of the driving assembly 40, the sensing member 72 is disposed on the first housing 11, the motor shaft rotates to drive the sensor 71 to rotate, and the sensor 72 senses the rotation once per rotation, so that the sensor 71 can sense the number of rotations of the motor shaft, and then calculate the distance that the motor 411 drives the second housing 12 to move through the transmission ratio.

In addition, in the illustrated embodiment, the sensor 71 is provided on the first housing 11, and the sensing member 72 is provided on the second housing 12. It is understood that in other embodiments, the sensor 71 may be disposed on the second housing 12, and the sensing member 72 may be disposed on the first housing 11, only when the second housing 12 moves, the two can move relatively.
