It will be appreciated that the relative movement of the first and

second housings

11, 12 may be achieved by a drive means 40 mounted within the receiving cavity 31 of the guide shaft 30. In some embodiments, the first housing 11 of the electronic device 100 may serve as a main body supporting structure of the electronic device 100, and the first housing 11 may include components such as the guide shaft 30, the speaker, the circuit board, and the battery therein. Additionally, in some embodiments, the second shell 12 may be slightly smaller than the first shell 11, such that the second shell 12 may also be entirely collapsed inside the first shell 11. In some embodiments, the first housing 11 and the second housing 12 may have similar shapes, and the second housing 12 and the first housing 11 cooperate to form a complete support structure, which makes the flexible display 20 symmetrical and beautiful when unfolded.

Specifically, in the illustrated embodiment, the first housing 11 is slidably connected to the second housing 12, and the second portion 22 of the flexible display 20 can be disposed inside the housing assembly 10 in a hidden configuration. Referring to fig. 2, in the first mode, the second portion 22 of the flexible display 20 is not used for displaying, and only the first portion 21 is used for displaying. The second housing 12 moves away from the first housing 11 to move the flexible display 20, such that the second portion 22 of the flexible display 20 is at least partially pulled out of the housing assembly 10 to switch to the second configuration. In the second configuration, the second portion 22 is at least partially pulled out of the housing assembly 10, and the first portion 21 and the second portion 22 are simultaneously used for displaying, thereby changing the display area of the electronic device 100.

The guide shaft 30 is provided with the accommodating cavity 31, the driving device 40 can be installed in the accommodating cavity 31, and the driving device 40 does not occupy the space in the housing assembly 10 additionally, so that the design of the electronic device 100 is more compact, and the space utilization rate of the electronic device 100 is improved. It is understood that the saved space can be used to reduce the overall size of the electronic device 100, so that the electronic device 100 is more compact and more delicate.

In addition, it should be noted that, in the description of the present application, it should be noted that, unless explicitly stated or limited otherwise, the terms "mounted," "connected," and "connected" are to be interpreted broadly, e.g., as either a fixed connection, a detachable connection, or an integral connection; may be a mechanical connection; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art as appropriate.

Referring to fig. 4 and 5, in some embodiments, the electronic device 100 further includes a transmission assembly 50, the transmission assembly 50 is mounted on the first housing 11 and located outside the accommodating cavity 31, the transmission assembly 50 is connected to the driving device 40 and the second housing 12, and the driving device 40 is configured to drive the second housing 12 to move relative to the first housing 11 through the transmission assembly 50.

In this way, the driving device 40 can drive the second housing 12 to move relative to the first housing 11 through the transmission assembly 50 to realize relative displacement, so as to realize the conversion between the two states of the electronic device 100.

In the embodiment of the present application, the driving device 40 may be the motor 41, and the type of the transmission assembly 50 is not limited, and the transmission assembly 50 may be a transmission structure that can convert rotation into linear motion, such as a conveyor belt structure, a chain transmission structure, a rack and pinion structure, and a lead screw nut structure, and the like, and is not limited herein. Specifically, when the power is turned on, the motor shaft of the motor 41 rotates, the transmission assembly 50 is located outside the accommodating cavity 31 and can be connected to the motor shaft of the driving device 40 and convert the rotation of the motor shaft into a linear motion, and at least a portion of the transmission assembly 50 is fixedly connected to the second shell 12 to ensure that the transmission assembly 50 can drive the second shell 12 to move linearly. The driving device 40 and the transmission assembly 50 are mounted on the first housing 11, and the transmission assembly 50 connects the driving device 40 and the second housing 12 such that the transmission assembly 50 connects the first housing 11 and the second housing 12, and the driving device 40 drives the second housing 12 to move relative to the first housing 11 through the transmission assembly 50.

Further, referring to fig. 4 and 5, in some embodiments, the transmission assembly 50 includes a transmission belt 51, a first transmission wheel 52 and a second transmission wheel 53, the first transmission wheel 52 and the second transmission wheel 53 are spaced apart from each other, the transmission belt 51 is wound around the first transmission wheel 52 and the second transmission wheel 53, the second shell 12 is connected to the transmission belt 51, and the driving device 40 is configured to drive the first transmission wheel 52 to rotate, so as to drive the transmission belt 51 to drive the second shell 12 to move, so as to at least partially extend the second portion 22 out of the housing assembly 10 or retract the second portion 22 into the housing assembly 10.

Thus, the first transmission wheel 52 and the second transmission wheel 53 are spaced apart and move in cooperation with the transmission belt 51 to convert the rotational motion of the driving device 40 into a linear motion, thereby driving the second housing 12 to slide relative to the first housing 11.

Specifically, a first driving wheel 52 and a second driving wheel 53 are respectively disposed at both ends of the first housing 11, and the conveyor belt 51 is wound around the first driving wheel 52 and the second driving wheel 53, so that the conveyor belt 51, the first driving wheel 52 and the second driving wheel 53 form a complete transmission mechanism. The first driving wheel 52 can be used as a driving wheel, the driving device 40 is connected with the first driving wheel 52 to drive the first driving wheel 52 to rotate, the first driving wheel 52 drives the conveying belt 51 to move, the conveying belt 51 drives the second driving wheel 53 to rotate, and the second driving wheel 53 is used as a driven wheel to assist the conveying belt 51 to move. The conveyor belt 51 is fixedly connected to the second casing 12, the conveyor belt 51 moves to drive the second casing 12 to move, and the first portion 21 of the flexible display 20 is fixedly connected to the second casing 12. In one example, the driving device 40 is used to drive the first driving wheel 52 to rotate clockwise, and the driving belt 51 drives the second shell 12 to move away from the first shell 11, so that the second portion 22 is at least partially unfolded out of the housing assembly 10. In another example, the driving device 40 is used to drive the first driving wheel 52 to rotate counterclockwise, and the driving belt 51 drives the second housing 12 to move toward the first housing 11, so that the second portion 22 is at least partially retracted into the housing assembly 10.

In this way, the driving device 40 can drive the first driving wheel 52 to rotate to drive the driving belt 51 to move. Because the second shell 12 and the second portion 22 of the flexible display screen 20 are respectively and fixedly connected to two sides of the conveyor belt 51, the conveyor belt 51 can drive the second shell 12 to move relative to the first shell 11 and also drive the second portion 22 to move, so that the second portion 22 can be unfolded out of the housing assembly 10 or retracted into the housing assembly 10.

second drive wheels

52, 53, respectively, to enable the second portion 22 to cooperate with the second housing 12. It is ensured that the conveyor belt 51 can move the second part 22 while moving the second shell 12 so that the second part 22 is at least partially extended out of the housing assembly 10 or retracted into the housing assembly 10.

Referring to fig. 4 to 7, in some embodiments, the conveyor belt 51 has a first mounting hole 511 and a second mounting hole 512 formed thereon, and the electronic device 100 further includes a first fastener 513 and a second fastener 514, wherein the first fastener 513 is disposed through the first mounting hole 511 and fixedly connected to the second housing 12, and the second fastener 514 is disposed through the second mounting hole 512 and fixedly connected to the second portion 22.

As such, first mounting hole 511 in cooperation with first fastener 513 may enable conveyor belt 51 and second housing 12 to be at least partially secured together, and second mounting hole 512 in cooperation with second fastener 514 may enable conveyor belt 51 and second portion 22 to be at least partially secured together, such that second portion 22 may also be at least partially deployed out of housing assembly 10 or retracted into housing assembly 10 under the influence of conveyor belt 51 while second housing 12 is moving. The stroke of movement of the second portion 22 is equal to the stroke of movement of the second shell 12.

Specifically, the first mounting hole 511 may be disposed at an upper side of the first driving wheel 52, and the second mounting hole 512 may be disposed at a lower side of the second mounting hole 512. The first fastener 513 is disposed through the first mounting hole 511 and fixedly connected to the second housing 12 to fix the conveyor belt 51 to the second housing 12. The second fastening member 514 is disposed through the second mounting hole 512 and fixedly connected to the second portion 22 to fix the conveyor belt 51 to the second portion 22. In this way, the conveyor belt 51 may be used to effect coordinated movement of the second housing 12 and the flexible display screen 20. In the embodiment shown in fig. 5 and 6, the second fastener 514 is installed through the second installation hole 512, and the first fastener 513 is not shown.

In this embodiment, the second housing 12 may be directly fixedly connected to the conveyor belt 51 by the first fastener 513, or the conveyor belt 51 and the first portion 21 of the flexible display 20 may be fixedly connected by the first fastener 513, so as to achieve an indirect fixed connection between the second housing 12 and the conveyor belt 51, which is not limited herein. In the illustrated embodiment, the second fastening member 514 is connected to the tail of the second portion 22 and fixes the tail of the second portion 22 to the conveyor belt 51, and in other embodiments, the second fastening member 514 may be connected to other portions of the second portion 22, and is not limited herein.

Further, the first and second mounting

holes

511 and 512 may be screw holes, and the first and

second fasteners

513 and 514 may be screws, and the fixing of the conveyor belt 51 and the second housing 12 to the flexible display 20 is achieved by the screw and screw hole structures, respectively. In the embodiment of the application, the types of the mounting holes and the fasteners are not limited, and the requirements can be met.

Referring to fig. 4 and 5, in some embodiments, the conveyor belt 51 is formed with a first tooth 515, the first drive wheel 52 is formed with a second tooth 521, the second drive wheel 53 is formed with a third tooth 531, and both the second tooth 521 and the third tooth 531 are engaged with the first tooth 515.

In this way, the conveyor belt 51 and the first transmission wheel 52 are engaged by the first tooth 515 and the second tooth 521, and the conveyor belt 51 and the second transmission wheel 53 are engaged by the first tooth 515 and the third tooth 531, so as to realize the function of the transmission assembly 50.

Specifically, the first tooth 515 of the conveyor belt 51 may be formed at an inner surface of the transmission wheel, the second tooth 521 of the first transmission wheel 52 may be formed at an outer surface of the first transmission wheel 52, and the third tooth 531 of the second transmission wheel 53 may be formed at an outer surface of the second transmission wheel 53. The conveyor belt 51 is wound around the first and

second transmission wheels

52 and 53 such that the second and

third teeth

521 and 531 are engaged with the first tooth 515. The first transmission wheel 52 is driven to rotate by the driving device 40, the second tooth 521 is meshed with the first tooth 515 to drive the transmission belt 51 to move, and the second tooth 521 is meshed with the third tooth 531 to drive the second transmission wheel 53 to rotate. The conveyor belt 51 is fixedly connected to the second housing 12 and the second portion 22 by fasteners and mounting holes, respectively, such that the second portion 22 is at least partially deployed out of the housing assembly 10 or retracted into the housing assembly 10.

Referring to fig. 4 and 5, in some embodiments, the first driving wheel 52 and the second driving wheel 53 have a frictional resistance with the conveyor belt 51, and the first driving wheel 52 drives the conveyor belt 51 to move through the frictional resistance.

In this manner, the conveyor belt 51 cooperates with the first and

second transmission wheels

52, 53 by friction to perform the function of the transmission assembly 50.

Specifically, since the transmission assembly 50 is applied to the electronic device 100 of the present application, the driving force generated by the driving device 40 is not too large, and thus the transmission force received by the transmission assembly 50 is not too large. In this way, the transmission belt 51, the first transmission wheel 52 and the second transmission wheel 53 may directly realize transmission by friction force without forming a tooth part, so that the transmission assembly 50 has a simpler structure. The conveyor belt 51 can be sleeved on the first transmission wheel 52 and the second transmission wheel 53 in a relatively tight manner, so that the conveyor belt 51, the first transmission wheel 52 and the second transmission wheel 53 are prevented from being too loose to cause transmission failure.

Of course, in the above-described embodiment, the second shell 12 and the second portion 22 can be moved simultaneously by means of the conveyor belt 51 to move the second shell 12, while the second portion 22 can also follow the movement. It is understood that in other embodiments, the transmission manner for driving the second housing 12 to move relative to the first housing 11 may also be a gear-rack transmission or a lead screw-nut transmission, etc. which can convert the rotation of the motor 41 into a linear motion. For example, in one example, the driving device 40 may be a motor 41, the motor 41 may be connected to and drive a gear, the gear may be connected to a rack, the gear and the rack may cooperate to convert a rotational motion into a linear motion, and the rack may be fixed to the second housing 12 to ensure a synchronous motion with the second housing 12. The motor 41 rotates to generate a driving force to drive the gear to rotate, the gear is meshed with the rack, and the rack is fixed with the second shell 12 and moves along a straight line under the action of the gear. Of course, it is understood that in other embodiments, the second portion 22 may be deployed and stored by rolling and releasing the second portion 22 with a reel, and the deployment and the retraction of the second portion 22 may be achieved while the second shell 12 moves.

Referring to fig. 4 and 5, in some embodiments, the driving device 40 includes a motor 41 and a speed changing assembly 42, the speed changing assembly 42 and the motor 41 are both disposed in the accommodating cavity 31, and the speed changing assembly 42 connects the motor 41 and the transmission assembly 50.

Thus, the speed changing assembly 42 and the motor 41 are both disposed in the accommodating cavity 31, and do not occupy the space in the housing assembly 10, so as to improve the space utilization rate, and the motor 41 and the speed changing assembly 42 realize the basic function of the driving transmission assembly 50.
