DETAILED DESCRIPTION

[0037] To make the purposes, features, and advantages of the present disclosure more apparent and understandable, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present disclosure without creative work shall fall within the scope of protection of the present disclosure.

[0038] Refer to Figures 1 to 4, wherein Figures 1 and 2 are schematic diagrams of the structure when the sliding part 12 is in the first position relative to the fixed part 11, and Figure 2 is the side opposite to Figure 1. Figures 3 and 4 are schematic diagrams of the structure when the sliding part 12 is in the second position relative to the fixed part 11, and Figure 4 is the side opposite to Figure 3. An embodiment of the present disclosure provides an electronic device, the electronic device includes a first body 1 and a second body 2, the first body 1 and the second body 2 are connected by a hinge so that the first body 1 and the second body 2 can be folded or unfolded relative to each other. The electronic device of the embodiment of the present disclosure includes a laptop computer, the first body 1 is the display part of the laptop computer, and the second body 2 is the control part of the laptop computer.

[0039] In the disclosed embodiment, referring to Figures 2, 4, and 5 to 8, Figures 5 and 6 illustrate the structure of the device when the sliding portion 12 is in a first position relative to the fixed portion 11, with Figure 6 showing the side opposite to Figure 5. Figures 7 and 8 illustrate the structure of the device when the sliding portion 12 is in a second position relative to the fixed portion 11, with Figure 8 showing the side opposite to Figure 7. The first body 1 includes a fixed portion 11, a sliding portion 12, a driving assembly 13, and a flexible screen 3. The fixed portion 11 is hingedly connected to the second body 2; the sliding portion 12 is slidably connected to the fixed portion 11; the driving assembly 13 is disposed on the fixed portion 11 and is configured to drive the sliding portion 12 to slide relative to the fixed portion 11; the flexible screen 3 has a first edge 31 and a second edge 32 disposed opposite to each other, with the first edge 31 disposed on the sliding portion 12 and the second edge 32 disposed on the second body 2. The flexible screen 3 can be at least partially receivable within the first body 1 via its first edge 31 and / or at least partially receivable within the second body 2 via its second edge 32, to accommodate the overall dimensions of the fixed portion 11 and the sliding portion 12.

[0040] The sliding portion 12 slides relative to the fixed portion 11, so that the overall size of the fixed portion 11 and the sliding portion 12 changes accordingly, that is, the area of ​​the first body 1 can be changed. The sliding portion 12 slides relative to the fixed portion 11 to move closer to or away from the end connected to the second body 2.

[0041] The fixed portion 11 includes an opposing first end 111 and a second end 112, and the sliding portion 12 has an opposing third end 121 and a fourth end 122. The first end 111 of the fixed portion 11 is connected to the second body 2 via a hinge, and the second end 112 is connected to the sliding portion 12. The third end 121 of the sliding portion 12 is closer to the first end 111 of the fixed portion 11 than the fourth end 122. When the sliding portion 12 moves relative to the fixed portion 11 in a direction away from the first end 111 of the fixed portion 11, the overall size of the fixed portion 11 and the sliding portion 12 increases accordingly. When the sliding portion 12 moves relative to the fixed portion 11 in a direction toward the first end 111 of the fixed portion 11, the overall size of the fixed portion 11 and the sliding portion 12 decreases accordingly.

[0042] The flexible screen 3 can adapt to the overall size of the fixed portion 11 and the sliding portion 12. When the overall size of the fixed portion 11 and the sliding portion 12 increases, the portion of the flexible screen 3 that is accommodated decreases accordingly, allowing the exposed portion of the flexible screen 3 to adapt to the increased area of ​​the first body 1, thereby increasing the portion of the flexible screen 3 used for display. When the overall size of the fixed portion 11 and the sliding portion 12 decreases, the portion of the flexible screen 3 that is accommodated increases accordingly, allowing the exposed portion of the flexible screen 3 to adapt to the decreased area of ​​the first body 1, thereby reducing the portion of the flexible screen 3 used for display. By allowing the fixed portion 11 to move relative to the sliding portion 12, the area of ​​the first body 1 can be adapted to that of the second body 2, making it easier to carry. Alternatively, by allowing the fixed portion 11 to move relative to the sliding portion 12, the area of ​​the first body 1 can be larger than that of the second body 2, thereby increasing the display size of the display screen, thus resolving the contradiction between minimizing the size of the electronic device and maximizing the display size.

[0043] To adapt to the dimensional changes caused by the movement of the fixed portion 11 relative to the sliding portion 12, the flexible screen 3 can be partially retracted within the first body 1 via the first edge 31. The second edge 32 is fixedly connected to the first end 111 of the fixed portion 11, and the flexible screen 3 is slidably connected to the fourth end 122 of the sliding portion 12. The first edge 31 is located within the first body 1. As the flexible screen 3 adapts to the changes in the overall size of the fixed portion 11 and the sliding portion 12, the amount of flexible screen 3 that can be accommodated changes accordingly. As the overall size of the fixed portion 11 and the sliding portion 12 increases, the flexible screen 3 retracted within the first body 1 is released to accommodate the increased size of the first body 1. The portion of the flexible screen 3 used for display increases as the size of the first body 1 increases, and the length of the released flexible screen 3 is equal to the distance the sliding portion 12 moves relative to the fixed portion 11. As the overall size of the fixed portion 11 and the sliding portion 12 decreases, the excess portion of the flexible screen 3 is retracted within the first body 1 via the first edge 31, and the portion of the flexible screen 3 used for display decreases as the size of the first body 1 decreases.

[0044] To accommodate dimensional changes caused by the movement of the fixed portion 11 relative to the sliding portion 12, the flexible screen 3 can also be partially retracted within the second body 2 via the second edge 32, with the first edge 31 fixedly connected to the fourth end 122 of the sliding portion 12. As the flexible screen 3 adapts to changes in the overall size of the fixed portion 11 and sliding portion 12, the amount of flexible screen 3 that can be accommodated changes accordingly. As the overall size of the fixed portion 11 and sliding portion 12 increases, the flexible screen 3 retracted within the second body 2 is released to accommodate the increased size of the first body 1. The portion of the flexible screen 3 used for display increases as the size of the first body 1 increases, and the length of the released flexible screen 3 is equal to the distance the sliding portion 12 moves relative to the fixed portion 11. As the overall size of the fixed portion 11 and sliding portion 12 decreases, the excess portion of the flexible screen 3 is retracted within the second body 2 via the second edge 32, and the portion of the flexible screen 3 used for display decreases as the size of the first body 1 decreases. Because the first edge 31 is fixed to the fourth end 122, as the overall size of the first body 1 increases, the first edge 31 moves with the sliding portion 12, releasing the flexible screen 3 housed within the second body 2. When the size of the display portion of the flexible screen 3 is increased, the electronic device is in use, the first body 1 is opened to a certain angle relative to the second body 2, for example, an angle of 110°, the first edge 31 is fixed to the fourth end 122, and the second edge 32 is located within the second body 2, which can prevent the flexible screen 3 from folding at a large angle during movement.

[0045] Alternatively, as the flexible screen 3 adapts to the size changes caused by the movement of the fixed portion 11 relative to the sliding portion 12, the first edge 31 is partially retracted within the first body 1, while the second edge 32 is partially retracted within the second body 2, leaving the flexible screen 3 slidably connected to the fourth end 122. As the flexible screen 3 adapts to the changes in the overall size of the fixed portion 11 and sliding portion 12, the amount of flexible screen 3 retracted changes accordingly. As the overall size of the fixed portion 11 and sliding portion 12 increases, the flexible screen 3 retracted within the first and second bodies 1 and 2 is released to accommodate the increased size of the first body 1. The portion of the flexible screen 3 used for display increases as the size of the first body 1 increases, and the length of the released flexible screen 3 is equal to the distance the sliding portion 12 moves relative to the fixed portion 11. As the overall size of the fixed portion 11 and sliding portion 12 decreases, the excess portion of the flexible screen 3 is retracted within the first body 1 via the first edge 31 and second edge 32, and the portion of the flexible screen 3 used for display decreases as the size of the first body 1 decreases.

[0046] The drive assembly 13 is located on the fixed portion 11. When the drive assembly 13 drives the sliding portion 12 to slide relative to the fixed portion 11, the size of the first body 1 changes accordingly. The flexible screen 3 adapts to the changes in the size of the first body 1, thereby increasing the display area. The drive assembly 13 is located in the first body 1 and can directly drive the sliding portion 12, ensuring smoother movement of the sliding portion 12. The location of the drive assembly 13 in the first body 1 avoids occupying space in the second body 2, eliminating the need to redesign the internal layout of the second body 2.

[0047] Referring to FIG9 , in one embodiment, the drive assembly 13 includes a motor 131, a screw rod 132, and a slider 133. The motor 131 is fixed to the fixed portion 11. The screw rod 132 is rotatably mounted on the fixed portion 11 and is driven to rotate by the motor 131. The slider 133 is threadedly connected to the screw rod 132 and moves along the screw rod 132 as the screw rod 132 rotates. The slider 133 is fixedly connected to the sliding portion 12 so that the sliding portion 12 moves relative to the fixed portion 11 under the drive of the slider 133. When the motor 131 drives the screw rod 132 to rotate, because the slider 133 is threadedly connected to the screw rod 132 and is fixed to the sliding portion 12, the slider 133 moves axially along the screw rod 132, simultaneously driving the sliding portion 12 to move therewith. The motor 131 can drive the screw 132 to rotate in a first direction or in an opposite second direction. This allows the slider 133 to reciprocate along the axis of the screw 132, driving the sliding portion 12 to reciprocate, thereby increasing or decreasing the size of the first body 1. The slider 133 is directly fixed to the sliding portion 12 and can smoothly drive the sliding portion 12 to move.

[0048] 9 , in one embodiment, the drive assembly 13 further includes a base 134 connected to the fixing portion 11 , and the motor 131 , the screw rod 132 , and the slider 133 are disposed on the base 134 . The drive assembly 13 is assembled into one piece via the base 134 , facilitating assembly of the electronic device.

[0049] 9 , in one embodiment, the drive assembly 13 further includes a guide rail 135 disposed on the base 134 and parallel to the screw rod 132. The slider 133 is slidably connected to the guide rail 135. By providing the guide rail 135, the slider 133 slides along the guide rail 135, thereby ensuring smooth operation of the slider 133.

[0050] Referring to FIG9 , in one embodiment, a rotation sensor 4 is provided on the base 134. The rotation sensor 4 is used to detect the rotation state of the motor 131. The electronic device determines the operating state of the drive assembly 13 based on the signal detected by the rotation sensor 4 and the position of the slider 133. When the slider 133 moves to the target position, such as the first position or the second position, if the rotation sensor 4 detects that the motor 131 is not rotating, the electronic device determines that the drive assembly 13 is operating normally; otherwise, the drive assembly 13 is malfunctioning. Alternatively, when the slider 133 does not move to the target position, such as the first position or the second position, if the rotation sensor 4 detects that the motor 131 is rotating, the electronic device determines that the drive assembly 13 is operating normally; otherwise, the drive assembly 13 is malfunctioning. The rotation sensor 4 includes an encoder.

[0051] Referring to Figure 9, in one embodiment, a position sensor 6 is provided on the base 134, and the position sensor 6 is used to check the position of the slider 133. The electronic device instructs the motor 131 to start or stop according to the detection signal of the sensor. The sliding portion 12 can move between a first position and a second position relative to the fixed portion 11. In the first position, the overall size of the sliding portion 12 and the fixed portion 11 is the smallest, and in the second position, the overall size of the sliding portion 12 and the fixed portion 11 is the largest. Depending on the position of the sliding portion 12 relative to the fixed portion 11, the electronic device can have different forms. When the sliding portion 12 is in the first position relative to the fixed portion 11, the electronic device is in the first form, and the size of the portion of the flexible screen 3 used for display is the smallest. When the sliding portion 12 is in the second position relative to the fixed portion 11, the electronic device is in the second form, and the size of the portion of the flexible screen 3 used for display is the largest.

[0052] The electronic device may have only a first configuration and a second configuration. Specifically, when the sliding portion 12 moves relative to the fixed portion 11 to the first position or the second position, the position sensor 6 detects the position of the slider 133 to determine whether the sliding portion 12 has reached the first position or the second position and issues a detection signal. Based on the detection signal, the electronic device instructs the motor 131 to stop when the sliding portion 12 moves to the first position or the second position. Two position sensors 6 may be provided, one at each end of the screw rod 132, to detect the position of the slider 133.

[0053] The electronic device may also have an intermediate form in addition to the first form and the second form, that is, the sliding portion 12 can move relative to the fixed portion 11 to one or more positions between the first position and the second position, so that the electronic device can have a wider range of display sizes. The position sensor 6 is capable of detecting any position of the slider 133 between the first position and the second position. The position sensor 6 may include a sliding resistor structure. As the slider 133 moves axially along the screw rod 132, the current generated by the sliding resistor structure changes linearly. The position of the slider 133 can be determined based on the current signal output by the sliding resistor structure. When the slider 133 moves to the target position, the electronic device instructs the motor 131 to stop.

[0054] In one embodiment, there are at least two groups of driving components 13 , and the at least two groups of driving components 13 are arranged in parallel on the fixing portion 11 . The at least two groups of driving components 13 arranged in parallel jointly drive the sliding portion 12 to move relative to the fixing portion 11 .

[0055] In one embodiment, the second edge 32 is connected to one end of the tension cord 5, and the other end of the tension cord 5 is connected to the first edge 31 by passing through the first structure 8 provided on the second body 2. The tension cord 5 connects the first edge 31 and the second edge 32 respectively, so that the flexible screen 3 remains flat during the overall size change of the fixed part 11 and the sliding part 12.

[0056] 2 and 4 , in one embodiment, first edge 31 is fixed to sliding portion 12, second edge 32 is disposed within second body 2, and second edge 32 is connected to one end of tension cord 5. The other end of tension cord 5 passes through first structure 8 disposed on second body 2, passes through second structure 9 disposed on fixing portion 11, and is connected to sliding portion 12. Both ends of tension cord 5 are located between first structure 8 and second structure 9.

[0057] When the sliding portion 12 moves to the second position relative to the fixed portion 11, the first edge 31 is fixed to the fourth end 122 of the sliding portion 12, so the first edge 31 of the flexible screen 3 moves with the sliding portion 12, releasing the flexible screen 3 housed in the second body 2. The second edge 32 moves toward the hinge, and the end of the tension rope 5 connected to the second edge 32 moves accordingly. The tension rope 5 passes around the first structure 8 and the second structure 9, pulling the other end. The other end of the tension rope 5 is connected to the sliding portion 12 and moves with the sliding portion 12. During this process, the tension rope 5 keeps the flexible screen 3 flat.

[0058] When the sliding portion 12 moves toward the first position relative to the fixed portion 11, the end of the tension cord 5 connected to the sliding portion 12 moves accordingly. The tension cord 5 passes over the second structure 9 and the first structure 8 and pulls the end connected to the second edge 32, thereby partially storing the flexible screen 3 within the second body 2 through the second edge 32. During this process, the tension cord 5 keeps the flexible screen 3 flat.

[0059] The first structure 8 and the second structure 9 may respectively include pulleys 75, and the tension rope 5 is respectively passed around the pulleys 75 of the first structure 8 and the pulleys 75 of the second structure 9. The pulleys 75 can reduce the resistance to the movement of the tension rope 5.

[0060] In one embodiment, the tension rope 5 may have a certain degree of elasticity. The tension rope 5 is an elastic rope, which can provide tension to the flexible screen 3, maintain the tension of the flexible screen 3, and keep the flexible screen 3 flat.

[0061] 10 , in one embodiment, a tensioning mechanism 7 is provided on the second body 2, and the tensioning mechanism 7 is used to enable the tension rope 5 to provide tension to the flexible screen 3. At least one of the first structure 8 and the second structure 9 is a tensioning mechanism 7, or a tensioning mechanism 7 is provided separately.

[0062] Referring to FIG. 10 , in one embodiment, the tensioning mechanism 7 includes a base 71, a slide rod 72, a slide seat 73, a spring 74, and a pulley 75. The slide rod 72 is mounted on the base 71, and the slide seat 73 is slidably connected to the slide rod 72. Specifically, the slide seat 73 may be sleeved on the slide rod 72, and the spring 74 may be sleeved on the slide rod 72. One end of the spring 74 abuts the base 71, and the other end abuts the slide seat 73. The pulley 75 is mounted on the slide seat 73. The tension rope 5 passes over the pulley 75. Under the action of the spring 74, the pulley 75 acts on the tension rope 5, maintaining tension in the tension rope 5. The tension rope 5 reacts against the pulley 75 to offset the elastic force applied by the spring 74 to the slide seat 73. When the first structure 8 is the tensioning mechanism 7, the base 71 is fixed to the second body 2. When the second structure 9 is the tensioning mechanism 7, the base 71 is connected to the fixing portion 11. There can be two slide bars 72 , which are arranged in parallel, and a spring 74 is sleeved on each slide bar 72 .

[0063] The tensioning mechanism 7 may further include a limit seat 76 disposed on the base 71 and having two limit slots, with the ends of the tension rope 5 passing around the pulley 75 respectively located in one limit slot. The limit seat 76 can prevent the tension rope 5 from falling off the pulley 75.

[0064] In one embodiment, a posture sensor is provided on the first body 1 for detecting the posture of the first body 1 relative to the second body 2. The electronic device controls the drive assembly 13 based on the signal detected by the posture sensor. The posture sensor can detect whether the electronic device is in use. When the angle at which the first body 1 is unfolded relative to the second body 2 reaches a certain range, the electronic device can be determined to be in use. The electronic device can then control the drive assembly 13 to activate and adjust the position of the sliding portion 12 relative to the fixed portion 11, thereby automatically adjusting the size of the display area of ​​the flexible screen 3.

[0065] Of course, the movement of the sliding portion 12 relative to the fixed portion 11 can also be achieved through user operation. The electronic device may include an adjustment key, and the user operates the adjustment key by pressing, pushing, or other actions, so that the driving component 13 drives the sliding portion 12 to move relative to the fixed portion 11 to a corresponding position.

[0066] In an alternative embodiment, after turning on the electronic device, the user presses the adjustment key, which activates the drive assembly 13 and drives the sliding portion 12 to move from the first position to the second position relative to the fixed portion 11. Pressing the adjustment key again causes the drive assembly 13 to drive the sliding portion 12 to move from the second position to the first position relative to the fixed portion 11.

[0067] Alternatively, when the electronic device receives a shutdown instruction, it instructs the driving assembly 13 to drive the sliding portion 12 to move from the second position to the first position relative to the fixing portion 11 .

[0068] In another optional embodiment, when the user pushes the adjustment key in the first direction, the drive assembly 13 drives the sliding portion 12 to move from the first position to the second position relative to the fixed portion 11. When the user releases the adjustment key or the adjustment key reaches the second position, the drive assembly 13 stops. When the user pushes the adjustment key in the second direction, the drive assembly 13 drives the sliding portion 12 to move from the second position to the first position relative to the fixed portion 11. When the user releases the adjustment key or the adjustment key reaches the first position, the drive assembly 13 stops.

[0069] It should be understood that the various forms of the processes shown above can be used to reorder, add, or delete steps. For example, the steps described in this disclosure can be performed in parallel, sequentially, or in a different order, as long as the desired results of the technical solutions disclosed in this disclosure can be achieved.
