Referring to fig. 1 to 4, in the present embodiment, the flexible display 20 includes a flat portion 21 and an extension portion 22. The flat portion 21 is exposed outside the housing assembly 10. In particular, the flat portion 21 is arranged above the first portion 11 and is at least partially fixedly connected to the top surface of the first portion 11. The extension portion 22 can be hidden in the housing assembly 10, and one end of the extension portion 22 is connected to the flat portion 21, the other end is housed in the housing assembly 10, and the middle portion is wound around the second portion 12.
When the second portion 12 slides relative to the first portion 11 away from the first portion 11, the second portion 12 can bring the expansion portion 22 to be at least partially unfolded out of the housing assembly 10, so as to form a display portion of the electronic device 100 together with the expansion portion 21.
In this embodiment, the flat portion 21 may be fixed to the top surface of the first portion 11 by a double-sided adhesive tape or an optical adhesive tape. It will be appreciated that in other embodiments, other fixing means may be used, for example, magnetic means may be used for fixing, and in such embodiments, a magnetic element may be attached to the back of the flat portion 21, and the top of the first portion 11 may be made of 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 and fig. 3, when only the flat portion 21 of the flexible display screen 20 is exposed from the housing assembly 10, the display area of the electronic device 100 is small, and at this time, the first portion 11 and the second portion 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, the second portion 12 may be partially or entirely accommodated in the mounting cavity of the first portion 11.
Referring to fig. 2 and 4, when the second portion 12 slides relative to the first portion 11 to a side away from the first portion 11, the second portion 12 drives the extension portion 22 to at least partially extend out of the housing assembly 10 to adjust a display area of the electronic device 100, so that the exposed extension portion 22 and the extension portion 21 jointly form a display portion of the electronic device 100, and the display area is larger. When the second portion 12 is slid to the limit position in the direction away from the first portion 11, the exposed area of the expanded portion 22 is maximized and the display area is also maximized (see fig. 2), and at this time, the electronic device 100 is in the wide screen mode. It can be understood that, in the embodiment of the present application, in the wide screen mode, the second portion 12 is slidable relative to the first portion 11 to a side close to the first portion 11, so that the extension portion 22 can 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. 2 to the state shown in fig. 1. That is, in the embodiment of the present application, the second portion 12 can slide relative to the first portion 11 to cause the extension portion 22 to at least partially extend 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.
Furthermore, in the illustrated embodiment, the second portion 12 carries the extension portion 22 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 22 is only partially exposed from the housing assembly 10. It is understood that in some embodiments, the extension portion 22 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.
Specifically, referring to fig. 5, in one possible embodiment, the electronic device 100 may further include a reel 30, the reel 30 may be disposed in the housing assembly 10, the end of the extension portion 22 is wound on the reel 30, the middle portion is wound on the second portion 12, and when the second portion 12 moves away from the first portion 11, the second portion 12 drives the extension portion 22 to move so that the reel 30 gradually releases the extension portion 22, so that the extension portion 22 can be gradually unwound out of the housing assembly 10. When the second portion 12 moves in a direction approaching the first portion 11, the second portion 12 gradually releases the extension portion 22, and the extension portion 22 can be gradually rolled up by the roller 30 to be gradually retracted into the housing assembly 10. It is understood that in such an embodiment, a driving mechanism such as a motor may be connected to the winding shaft 30, and the motor may drive the winding shaft 30 to wind or release the expansion portion 22 so as to unwind and retract the expansion portion 22, of course, the winding shaft 30 may also be a structure such as a torsion spring to wind the expansion portion 22, and when the second portion 12 moves away from the first portion 11, the second portion 12 may drive the expansion portion 22 to unwind to the outside of the housing assembly 10 against the restoring force of the torsion spring, and particularly, without limitation, only the expansion portion 22 may be released and wound.
In another possible embodiment, a pulley block may be disposed on the second portion 12, and one end of the extension portion 22 may be fixedly connected to the first portion 11 after sequentially passing through the pulley block, so that when the second portion 12 moves relative to the first portion 11, the second portion 12 may drive the extension portion 22 to gradually extend out of the housing assembly 10 or retract into the housing assembly 10 through the pulley block, and the specific arrangement is not limited herein.
Referring to fig. 3 and 4, in the present embodiment, the driving assembly 40 may be disposed in the first portion 11. The driving assembly 40 includes a power mechanism 41 and a transmission mechanism 42, the power mechanism 41 is disposed in the first portion 11, the transmission mechanism 41 connects the power mechanism 41 and the second portion 12, and the power mechanism 41 is configured to drive the second portion 12 to slide relative to the first portion 11 through the transmission mechanism 42.
Referring to fig. 3, 4 and 6, in a possible embodiment, the power mechanism 41 includes a motor 411 and a gear set 412, the transmission mechanism 42 includes a rotating member 421 and a moving member (not shown) sleeved on the rotating member 421, the rotating member 421 is in threaded connection with the moving member, the moving member is fixedly connected to the second portion 12, the gear set 412 is connected to a motor shaft of the motor 411 and the rotating member 421, for example, one gear of the gear set 412 may be fixedly connected to the rotating member 421 or a tooth portion is formed on the rotating member 421, the motor 411 is configured to drive the rotating member 421 to rotate through the gear set 412, so as to drive the moving member to move on the rotating member 421, and further drive the second portion 12 to slide relative to the first portion 11, so that the expanding portion 22 can be expanded to the outside of the housing assembly 10 or. Thus, the gear set 412 can drive the rotation member 421 to rotate, so as to improve the smoothness and reliability of the rotation member 421, and the implementation manner is simple. That is, in the embodiment of the present application, the power mechanism 41 may be configured to drive the rotating member 421 to rotate to drive the second portion 12 to slide relative to the first portion 11, so that the extension portion 22 can be at least partially extended out of the housing assembly 10 or retracted into the housing assembly 10 to adjust the display area of the electronic device 100, and in particular, the manner of extending and retracting the extension portion 22 is described in detail above and will not be described repeatedly herein.
Specifically, in some embodiments, the rotating member 421 may be a lead screw, the lead screw is in threaded connection with the moving member, and the moving member may be a threaded sleeve, so that when the rotating member 421 rotates, the rotating member 421 can drive the moving member to move on the rotating member 421, so as to drive the second portion 12 to slide relative to the first portion 11, and further enable the expanding portion 22 to be at least partially expanded out of the housing assembly 10 or retracted into the housing assembly 10 to adjust the display area of the electronic device 100;
it will be appreciated that in other embodiments, the rotating member 421 of the transmission mechanism 42 may also be a worm, and in such embodiments, the transmission mechanism 42 may further include a worm wheel, and the second portion 12 may be provided with a rack portion, and the worm wheel is engaged with the worm wheel, and the worm wheel is directly engaged with the rack portion of the second portion 12 or engaged with the rack portion of the second portion 12 through a gear set, so that the second portion 12 can be driven to slide relative to the first portion 11 by rotating the worm wheel through the driving mechanism 41.
Furthermore, it is also understood that in some embodiments, the electronic device 10 may not include a moving member and directly screw the second portion 12 to the rotating member 421. For example, a threaded hole is formed on the second portion 12, and the rotating member 421 is threaded through the threaded hole to be in threaded connection with the second portion 12, so that when the rotating member 421 rotates, the second portion 12 can be directly driven to slide relative to the first portion 11 along the axial direction of the rotating member 421, that is, the axial direction of the rotating member 421 is parallel to the sliding direction of the second portion 12, and the invention is not limited thereto.
Referring to fig. 3 and 4, in the present embodiment, the first position detecting element 50 is disposed in the housing element 10, and the first position detecting element 50 is used for detecting a rotation angle of the rotating element 421 to detect a sliding distance of the second portion 12 relative to the first portion 11, so as to detect a display area of the electronic device 100.
In addition, the first position detecting assembly 50 is further configured to detect a rotation direction of the rotation member 421, when the rotation member 421 rotates along the first direction, the moving member drives the second portion 12 to slide relative to the first portion 11 so that the extension portion 22 can be at least partially extended out of the housing assembly 10, and when the rotation member 421 rotates along the second direction, the moving member drives the second portion 12 to slide in a reverse direction relative to the first portion 11 so that the extension portion 22 can be at least partially retracted into the housing assembly 10, where the first direction is opposite to the second direction.
It will be understood from the above description that, in the embodiment of the present application, the sliding distance of the second portion 12 relative to the first portion 11 is equal to the distance that the extension portion 22 is extended out of the housing assembly 10 or retracted into the housing assembly 10, that is, how much distance the extension portion 22 moves out of the housing assembly 10 when the second portion 12 moves away from the first portion 11, and how much distance the extension portion 22 moves into the housing assembly 10 when the second portion 12 moves closer to the first portion 11.
In this way, the second portion 12 can move relative to the first portion 11 under the driving of the rotating member 421, so that the extending portion 22 can be at least partially extended out of the housing assembly 10 or retracted into the housing assembly 10 to adjust the display area of the electronic device 100, the electronic device 100 can detect the rotating angle and the rotating direction of the rotating member 421 through the first position detecting assembly 50, so as to detect the sliding distance and the sliding direction of the second portion 12 relative to the first portion 11, and further detect the moving distance of the extending portion 22 to obtain the area of the extending portion 22 extended out of the housing assembly 10 or retracted into the housing assembly 10, so as to achieve the purpose of detecting the display area of the electronic device 100.
Herein, the "display area" refers to an area of a portion of the flexible display 20 exposed outside the housing assembly 10 for displaying, so that the sliding direction and the sliding distance of the second portion 12, that is, the area of the extended portion 22 exposed from the housing assembly 10, can be obtained only by detecting the rotating direction of the rotating angle of the rotating member 421, and thus, the display area of the electronic device 100 can be obtained only by adding the area of the extended portion 22 exposed to the area of the flat portion 21.
Specifically, taking the rotating member 421 as a lead screw as an example, the second portion 12 can be screwed with the lead screw through the moving member, so that when the lead screw rotates one turn along the first direction, the moving member moves on the lead screw by a distance of one pitch, so that the second portion 12 slides by a distance of one pitch to a side away from the first portion 11, and then the distance that the expanding portion 22 is expanded to the housing assembly 10 is obtained to obtain the current display area of the electronic device 100. When the screw rod rotates for one circle along the second direction, the moving member moves on the screw rod in the reverse direction for a distance of one screw pitch, so that the second portion 12 slides to a side close to the first portion 11 for a distance of one screw pitch, and then the distance for the extension portion 22 to retract into the shell assembly 10 is obtained, so that the current display area of the electronic device is obtained.
For example, when the first direction is clockwise and the second direction is counterclockwise, when the lead screw rotates 180 ° clockwise, the moving member and the second portion 12 both move by half a pitch to a side away from the first portion 11, so as to obtain a distance that the expanding portion 22 is expanded out of the housing assembly 10, and further obtain a current display area of the electronic device 100, in this case, the display area of the electronic device 100 gradually increases. Similarly, when the screw rod rotates counterclockwise, the moving member and the second portion 12 move in opposite directions, and the expanding portion 22 is driven by the winding shaft 30 or driven by the second housing 12 to gradually retract into the housing assembly, so that the first position detecting assembly 50 can also detect the angle of the screw rod rotating in opposite directions, thereby obtaining the distance between the moving member and the second portion 12 moving in opposite directions, and further obtaining the current display area of the electronic device 100. It is understood that, in other embodiments, the first direction may also be a counterclockwise direction, and the second direction may also be a clockwise direction, which is not limited herein.
Of course, it is understood that when the rotating member 421 is a worm, the moving distance of the second portion 12 can be calculated by the transmission ratio of the transmission mechanism 42, and therefore, the sliding distance of the second portion 12 relative to the first portion 11 can also be detected by the rotation angle of the rotating member 321, and the direction in which the second portion 12 slides can also be detected by the rotation direction, so as to obtain the distance that the expanding portion 22 extends out of the housing assembly 10 or retracts into the housing assembly 10 to obtain the current display area of the electronic device 100.
It can be understood that, in the embodiment of the present application, when a user needs to adjust the display area of the electronic device 100, a processor of the electronic device 100 disposed on the main circuit board 60 receives an adjustment instruction, so as to send a driving instruction to the driving assembly 40 through the processor, and the driving assembly 40 drives the rotating member 421 to rotate in the first direction or the second direction through the gear set 412 by the motor 411, so as to drive the second portion 12 to move, so that the expansion portion 22 can be at least partially expanded out of the housing assembly 10 or retracted into the housing assembly 10, thereby adjusting the display area of the electronic device 100. In this process, the first position detecting element 50 can detect the rotation angle of the rotating member 421 in real time, so as to detect the moving distance of the second portion 12, and further detect the real-time display area of the electronic device 100, and when the area of the electronic device reaches the display area desired by the user, the motor stops working.
Referring to fig. 3 and 4, in one embodiment, the first position detecting assembly 50 includes a first sensor 51 and a first sensing member 52. The first sensor 51 and the first sensing member 52 are arranged at an interval, the first sensor 51 is provided with a main circuit board 60, the main circuit board 60 is fixedly mounted on the first part 11, that is, the first sensor 51 is fixedly connected with the first part 11, the first sensing member 52 is fixedly connected with the rotating member 421 and can rotate along with the rotating member 421, and the first sensor 51 and the first sensing member 52 cooperate to detect the rotation angle of the rotating member 421. The first sensor 51 may transmit the detection information to a processor on the main circuit board 60 to enable the processor to control the operating state of the motor 411 of the driving assembly 40 according to the detection information.
In some embodiments, the first sensor 51 includes a first hall sensor, and the first sensing member 52 may include a first magnetic member, such as a magnet, for detecting a position of the first magnetic member, thereby detecting a rotation angle of the rotation member 421.
In this way, when the first magnetic member moves along with the rotating member 421, the first hall sensor can detect the rotating angle of the first magnetic member, so as to detect the rotating angle of the rotating member 4212 to obtain the sliding distance of the second portion 12, thereby achieving the purpose of detecting the display area of the electronic device 100.
Specifically, in such an embodiment, the first magnetic member may include two magnetic poles, i.e., an S pole and an N pole, and when the first magnetic member rotates along different directions along with the rotating member 421, a direction in which a magnetic field generated between the two magnetic poles of the first magnetic member passes through the first hall sensor may change, so that data collected by the first hall sensor changes to obtain a rotation angle and a rotation direction of the first magnetic member, i.e., a rotation angle of the rotating member 421.
In addition, in some embodiments, the first sensing element 52 of the first position detecting assembly 50 may also be disposed on a motor shaft of the motor 411 of the driving assembly 40, the motor shaft drives the first sensing element 52 to rotate when rotating, and the first sensor 51 may sense an angle of rotation of the first sensing element 52, so as to obtain a rotation angle of the motor, and further obtain a rotation angle of the rotating element 421, for example, when the motor shaft of the motor 411 is directly connected to the rotating element 421 and drives the rotating element 421 to rotate, the rotation angle of the motor shaft is the rotation angle of the rotating element 421, and when the motor shaft of the motor 411 is connected to the rotating element 421 through a transmission assembly such as a gear set, the rotation angle of the rotating element 421 may be calculated through a transmission ratio of the gear set.
Of course, in other embodiments, the first sensing element 52 may also be a magnetic ring disposed on the rotating element 421, and the magnetic ring has a plurality of N poles and S poles arranged at intervals along the circumferential direction, so that when the rotating element 421 drives the first sensing element 52 to rotate, the data output by the first sensor 51 changes, for example, in one example, when the N pole passes through the position of the first sensor 51, the first sensor 51 outputs a pulse signal, and when the S pole passes through the sensor, the first sensor 51 does not output a pulse signal, so that the angle rotated by the rotating element 521 can be calculated by calculating the number of pulses output by the first sensor 51.
In addition, in the above embodiment, the first sensor 51 is fixedly connected to the first portion 11, and the first sensing member 52 is fixedly connected to the rotating member. It is understood that in other embodiments, the first sensor 51 may be fixedly connected to the rotating component 421, and the first sensing component 52 is fixedly connected to the first portion 11, so that the rotation direction of the rotation angle of the rotating component can be detected only by relative movement of the two components when the second portion 12 moves.
It should be noted that in the embodiments of the present application, "fixedly connected" may be understood as one component being fixedly mounted on another component directly or indirectly through another component, and the two components cannot move relative to each other. For example, in the embodiment of the present application, the first sensor 51 is fixedly mounted on the main circuit board 60, the first sensor 51 is fixedly connected to the first portion 11 through the main circuit board 60, and the first sensing member 52 is directly fixedly mounted on the rotating member 421.
In addition, referring to fig. 3 and 4, in the illustrated embodiment, the first position detecting assembly 50 and the main circuit board 60 are disposed on the same side of the rotating member 421 in the axial direction, and the first position detecting assembly 50 is electrically connected to the main circuit board 60.
In this way, the first position detecting element 50 and the main circuit board 60 are disposed on the same side of the rotating member 421, so that the first position detecting element 50 can be conveniently installed to be electrically connected to the main circuit board 60, and the first position detecting element 50 is closer to the main circuit board 60, so that the first sensor 51 of the first position detecting element 50 can be directly disposed on the main circuit board 60 without using another connecting device for connection.
Of course, referring to fig. 7, it is understood that in other embodiments, the first position detecting assembly 50 and the main circuit board 60 may be disposed on opposite sides of the rotating member 421 in the axial direction. In such an embodiment, the electronic device 100 may further include a flexible circuit board 53, and the main circuit board 60 is electrically connected to the first position detecting assembly 50 through the flexible circuit board 53, and particularly, without limitation, it is only necessary to be able to electrically connect the main circuit board 60 and the first position detecting assembly 50.
Referring to fig. 3 and 4, in the embodiment of the present application, the electronic device 100 further includes a second position detecting assembly 70, and the second position detecting assembly 70 is used for detecting the relative position of the first portion 11 and the second portion 12.
As such, the relative positions of the first portion 11 and the second portion 12 may be detected by the second position detecting assembly 70 to determine whether the second portion 12 moves to the designated position. For example, the position information may be fed back to control the driving assembly 40 to stop working to prevent the motor 411 from being locked and even damaging the electronic device 100 when the second portion 12 moves to the side away from the first portion 11 and moves to the limit position when the second portion 12 moves to the side close to the first portion 11.
Referring to fig. 1 to 4, in the present embodiment, the second portion 12 can slide between a first position a and a second position B relative to the first portion 11, and when the second portion 12 is at the second position B, the display area of the electronic device 100 is larger than that of the electronic device 100 when the second portion 12 is at the first position a. The second position detecting assembly 70 includes a second sensor 71, a third sensor 72 and a second sensing member 73, the second sensing member 73 is fixedly connected to the second portion 12, for example, fixedly connected to the sliding rail 121 of the second portion 12, the second sensor 71 and the third sensor 72 are spaced apart from the first portion 11 and fixedly connected to the first portion 11, for example, fixedly connected to the fixed rail 111 of the first portion 11. Wherein the second sensor 71 is spaced from the second sensing member 73 to output a first position signal when the second portion 12 is in the first position a (see fig. 3), and the third sensor 72 is spaced from the second sensing member 73 to output a second position signal when the second portion 12 is in the second position B (see fig. 4).
It should be noted that, in the embodiment of the present application, the first position a is an extreme position when the second portion 12 moves toward the side close to the first portion 11, that is, the flexible display 20 is in the initial state, the extension portion 22 is completely hidden in the housing assembly 10, and the display area of the electronic device 100 is the minimum. The second position B is an extreme position when the second portion 12 moves to a side away from the first portion 11, that is, the flexible display 20 reaches a maximum stretching state, the area of the expansion portion 22 expanded to the outside of the housing assembly 10 is the maximum, and the display area of the electronic device 100 is the maximum.
Therefore, whether the second part 12 is located at the first position a and the second position B can be determined by the position signals output by the second sensor 71 and the third sensor 72, so as to determine whether the second part 12 moves to the extreme position to timely turn off the driving assembly 40, thereby preventing the electronic device 100 from being damaged by the motor 411 being locked.
Specifically, in some embodiments, the second sensor 71 includes a second hall sensor, the third sensor 72 includes a third hall sensor, and the second sensing member 73 includes a second magnetic member, such as a magnet, so that the second hall sensor and the third sensor 72 can detect the position of the second portion 12 relative to the first portion 11 by sensing the position of the second magnetic member.
When the second portion 12 is at the first position a, the second sensor 71 corresponds to the second sensing member 73, the second sensor 71 outputs the first position signal, the electronic device 100 is in the initial state, the display area is the minimum, and the extension portion 22 is substantially completely hidden in the housing assembly 10. In this case, when the rotating member 421 is gradually driven by the driving assembly 40 to rotate so as to drive the second portion 12 to gradually move away from the first portion 11, the expanding portion 22 gradually expands to the outside of the housing assembly 10, the display area of the electronic device 100 gradually increases, at this time, the second sensing member 73 gradually moves away from the second sensor 71 and gradually approaches the third sensor 72, when the second sensing member 73 moves to a position opposite to the third sensor 72, the third sensor 72 outputs a second position signal to indicate that the second portion 12 moves to the extreme position (i.e., the second position B), and the processor of the electronic device 100 receives the second position signal and controls the motor 411 of the driving assembly 40 to stop, at this time, the display area of the electronic device 100 is maximum.
In contrast, when the second portion 12 is in the second position B, the third sensor 72 corresponds to the second sensing member 73 and outputs a second position signal, in this case, when the rotation member 421 is gradually driven to rotate reversely by the driving assembly 40 so as to bring the second portion 12 closer to the first portion 11, the expanded portion 22 is gradually retracted into the housing assembly 10, and the display area of the electronic device 100 is gradually reduced, at this time, the second sensing member 73 is gradually distant from the third sensor 72 and gradually close to the second sensing member 73, when the second sensing member 73 moves to a position opposite to the second sensor 71, the second sensor 71 outputs a first position signal to indicate that the second portion 12 has moved to the limit position (i.e., the first position a), and the processor of the electronic device 100 receives the first position signal and controls the motor 411 of the driving assembly 40 to stop, wherein the display area of the electronic device 100 is at a minimum.
In addition, in the above embodiment, the second sensor 71 and the third sensor 73 are spaced apart and fixedly connected to the first portion 11, and the second sensing member 73 is fixedly connected to the second portion 12. It is understood that, in other embodiments, the second sensor 71 and the third sensor 72 may be fixedly connected to the second portion 12, and the second sensing member 72 is fixedly connected to the second portion 12, and it is only required that the second sensing member 71, the second sensor 71 and the third sensor 73 can move relatively when the second portion 12 moves, so that the position of the second portion 12 can be detected by the second sensor 71 and the third sensor 72, and the specific implementation is not limited herein.
It is understood that, in some embodiments, the second sensor 71 and the third sensor 72 may be both infrared sensors, the second sensing member 73 may be a reflecting member disposed on the second portion 12 and capable of reflecting infrared light, the infrared light reflected by the infrared sensors can be reflected back by the reflecting member, so that when the second sensing member 73 moves to a position corresponding to the second sensor 71 (i.e. the first position a) along with the second portion 12, the second sensor 71 can receive the infrared light reflected back by the second sensing member 73 to output a first position signal, when the second sensing member 73 moves to a position corresponding to the third sensor 73 (i.e. the second position B) along with the second portion 12, the third sensor 72 can receive the infrared light reflected back by the second sensing member 73 to output a second position signal, when the second portion 12 is located between the first position a and the second position B, since the second sensing member 73 cannot reflect infrared light to be received by the second sensor 71 and the third sensor 73 or the reflected light is less bright, neither the second sensor 71 nor the third sensor 72 outputs a position signal.
Next, the operation principle of the electronic device 100 according to the present embodiment will be described.
As described above, the electronic device 100 is switchable between the narrow-screen mode and the wide-screen mode, i.e., the second portion 12 is slidable relative to the first portion 11 between the first position a and the second position B, and in the state shown in fig. 1 and 3, the electronic device 100 is in the narrow-screen mode, i.e., the second portion 12 is in the first position a, and in the state shown in fig. 2 and 4, the electronic device 100 is in the wide-screen state, i.e., the second portion 12 is in the second position B. When in the narrow screen mode, the first portion 11 and the second portion 12 cooperate to form the housing assembly 10 of the electronic device 100, the flat portion 21 of the flexible display screen 20 is hidden from the housing assembly 10, and the extended portion 22 is hidden within the housing assembly 10. At this time, the area of the display area of the electronic device 100 is small, which is convenient for the user to carry.
When a user needs a large display area, the driving assembly 40 drives the rotating member 421 to rotate so as to drive the second portion 12 to slide towards a side far away from the first portion 11 relative to the first portion 11, the second portion 12 drives the extension portion 22 to gradually follow the movement, so that the extension portion 22 is smoothly unfolded out of the housing assembly 10, and the flat portion 21 and the extension portion 22 exposed out of the housing assembly 10 jointly form the display area of the electronic device 100, so that the area of the portion, exposed out of the housing assembly 10, of the flexible display screen 20 is large, at this time, the area of the display area is large, and the user can operate conveniently to improve the operation experience of the user.
In this process, the first position detecting element 50 can detect the rotation angle of the rotating element 421 in real time, so as to obtain the sliding distance of the second portion 12 to obtain the area of the extending portion 21 extending out of the housing element 10, thereby achieving the purpose of detecting the display area of the electronic device 100 in real time. In this process, when the second portion 12 is at the initial position (i.e., the first position a), the second sensor 71 of the second position detecting assembly 70 corresponds to the second sensing member 73, thereby outputting the first position information. When the second portion 12 gradually moves to the second position B, the second sensing member 73 moves to a position corresponding to the third sensor 72, and at this time, the third sensor 72 outputs second position information to control the motor 411 of the driving assembly 40 to stop operating, thereby completing the operation of enlarging the display area of the electronic device 100.
When it is required to switch from the wide screen mode to the narrow screen mode, the motor 311 of the driving assembly 40 is rotated in a reverse direction, so that the rotating member 421 rotates in a reverse direction, and the second portion 12 slides toward the side where the first portion 11 is located, and thus the second portion 12 gradually releases the extension portion 22, so that the extension portion 22 is gradually retracted into the housing assembly 10 under the action of the second portion 12 or the winding shaft 30, and when the first portion 11 and the second portion 12 are fitted together, the extension portion 22 is completely hidden in the housing assembly 10, and the electronic device 100 returns to the narrow screen mode (i.e., moves from the state shown in fig. 2 to the state shown in fig. 1).
In this process, the first position detecting element 50 can also detect the rotation angle of the rotating element 421 in real time, so as to obtain the sliding distance of the second portion 12 to obtain the area of the expanding portion 21 expanded outside the housing element 10, thereby achieving the purpose of detecting the display area of the electronic device 100 in real time. In this process, when the second portion 12 is in the second position B, the third sensor 72 of the second position detecting assembly 70 corresponds to the second sensing member 73, thereby outputting second position information. When the second portion 12 gradually moves to the first position a, the second sensing member 73 moves to a position corresponding to the second sensor 71, and at this time, the second sensor 72 outputs the first position information to control the motor 411 of the driving assembly 40 to stop operating, thereby completing the operation of reducing the display area of the electronic device 100.
It is understood that in the present embodiment, a user may input a desired value of the display area or input a command by pressing a switch button on the electronic device 100, a processor on the main circuit board 60 of the electronic device activates the motor 411 of the driving assembly 40 according to the input command, and the motor 411 drives the second portion 12 to move relative to the first portion 11, so that the expansion portion 22 is gradually expanded out of the housing assembly 10 or retracted into the housing assembly 10 to adjust the display area of the electronic device 100. In this process, the first position detecting element 50 can detect the rotation angle and the rotation direction of the rotating element 421 by the above detection method, so as to detect the display area of the electronic device 100, and when detecting that the display area reaches the value set by the user, the processor controls the driving element 40 to stop working, so that the electronic device 100 can realize the arbitrary switching of different display areas. It can be understood that when the sliding stroke of the second portion 12 is relatively long, the position detection by detecting the rotation angle of the rotation member 421 can ensure that the second portion 12 can achieve a very high positioning accuracy when forming the intermediate position, thereby implementing an accurate control of the display area of the electronic device 100.
Furthermore, it can be further understood that in the embodiment of the present application, when the motor 41 of the driving assembly 40 does not operate, the first sensor 51, the second sensor 71, and the third sensor 72 are all in the off state or in the interrupt state without performing position detection to save the power of the electronic device 100 and improve the cruising ability.
In summary, the electronic device 100 of the embodiment of the present application includes a housing assembly 10, a flexible display 20, a driving assembly 40, and a first position detecting assembly 50. The housing assembly 10 includes a first portion 11 and a second portion 12, the first portion 11 being slidably coupled to the second portion 12. The flexible display 20 includes a flat portion 21 exposed from the housing assembly 10 and an extension portion 22 capable of being hidden within the housing assembly 10, the flat portion 21 being connected to the first portion 11. The driving assembly 40 includes a power mechanism 41 and a transmission mechanism 42 connected to the power mechanism 41, the power mechanism 41 is disposed on the first portion 11, the transmission mechanism 42 includes a rotating member 421, the rotating member 421 is connected to the second portion 12, and the power mechanism 41 is configured to drive the rotating member 421 to rotate so as to drive the second portion 12 to slide relative to the first portion 11, so that the extending portion 22 can be at least partially extended out of the housing assembly 10 or retracted into the housing assembly 10 to adjust a display area of the electronic device 100. The first position detecting element 50 is used for detecting a rotation angle of the rotating member 421 to detect a sliding distance of the second portion 12 relative to the first portion 11, so as to detect a display area of the electronic device 100.
In summary, in the electronic device 100 according to the embodiment of the present application, the second portion 12 of the housing assembly 10 is capable of sliding relative to the first portion 11 under the action of the rotating element 42, so that the expansion portion 22 can be at least extended out of the housing assembly 10 or retracted into the housing assembly 10, thereby changing the display area of the electronic device 100, and the first position detecting element 50 can detect the rotating angle of the rotating element 421 to detect the sliding distance of the second portion 12, thereby detecting the display area of the electronic device 100. Thus, the first position detecting assembly 50 can more accurately locate the position of the second portion 12 by detecting the rotation angle of the rotation member 421, so as to locate the position of the flexible display screen 20, and further realize the detection of the display area of the electronic device 100, and even if the sliding stroke of the second portion 12 is far away, the detection of the rotation angle of the rotation member 421 can also realize the higher positioning precision to more accurately detect and adjust the display area of the electronic device 100.
