The processor can control the first telescopic element 3 to expand and contract, and the expansion and contraction of the first telescopic element 3 will generate a pushing or pulling force on the first connecting rod 11, thereby driving the first gear 9 to rotate in the first direction or in the second direction .

For example, the first connecting rod 11 is connected with the first gear 9. When the middle frame 1 and the foldable display screen 2 are in the unfolded state, if the processor controls the first telescopic element 3 to perform an extending motion, that is, the first telescopic element 3 When the length of the first telescopic element 3 increases, the first telescopic element 3 will generate a thrust to the first connecting rod 11 , and the thrust of the first connecting rod 11 will push the first gear 9 to rotate clockwise, thereby driving the second gear meshing with the first gear 9 10 rotates counterclockwise, since the positions of the first gear 9 and the second gear 10 relative to the bendable area 6 are unchanged, the rotation of the first gear 9 and the second gear 10 will also drive the bendable area. 6 Bend, and then drive the middle frame 1 and the foldable display screen 2 to fold.

When the processor receives the control command, the source of the control command can be physical buttons, virtual buttons, or fingerprint recognition or facial recognition, etc.; when the processor receives the control command, it will send to the first deformation block 22 The corresponding electrical signal is input to the second deformation block 27, for example, the positive conductive plate 25 of the first deformation block 22 is periodically energized, and the negative conductive plate of the second deformation block 27 is periodically energized, and then the first deformation block 22 is energized. When the deformation occurs in the first direction, the second deformation block 27 deforms in the second direction, and the first direction is opposite to the second direction, the first deformation block 22 pushes the first telescopic cavity 15 to move in the second direction, and the second deformation The block 27 pushes the second telescopic cavity 17 to move in the first direction, the first telescopic cavity 15 drives the first gear 9 to rotate counterclockwise through the first connecting rod 11 , and the second telescopic cavity 17 drives the second gear through the second connecting rod 14 10 is rotated clockwise to drive the bendable area 6 to flatten, so that the middle frame 1 and the foldable display screen 2 are switched to the unfolded state.

To achieve manual folding or unfolding, the embodiment of the present application avoids such time-consuming and labor-intensive operations, and can also avoid screen damage caused by excessive folding or excessive force by the user, further ensuring the reliability of the electronic device. and security.

Referring to FIG. 7 , an embodiment of the present application further provides a control method, which is applied to the electronic device described in the above embodiment. The control method includes:

Step 701: Receive a first input.

It should be noted that the first input may be an input operation acting on the hardware of the electronic device, such as pressing a specified physical button; or an input operation acting on a virtual button of the electronic device, such as acting on a specified virtual button or the electronic device may collect user-specified gestures, finger sliding tracks, fingerprint information, facial information, etc.

Step 702: In response to the first input, control the movement of the telescopic mechanism to drive the bendable area to bend, so that the electronic device is switched between a folded state and a moving state.

In the embodiment of the present application, when the electronic device receives the first input, in response to the first input, the telescopic mechanism is controlled to move to drive the bendable region to bend, so that the electronic device switches between the folded state and the motion state. For example, if the drive module in the telescopic mechanism is connected to the processor, the processor can input an electrical signal to the drive module in response to the first input, and the drive module drives the transmission assembly to move, so as to drive the bendable middle frame. The area bends or flattens, thereby enabling the electronic device to switch between a folded state and a motion state.

For example, the first input is a single-click operation acting on a designated virtual key of the electronic device. When the electronic device receives the first input, the processor responds to the first input, and if the middle frame is currently in the folded state, the processor responds to the folded state. The drive module inputs the first electrical signal, for example, periodically energizes the positive conductive plate of the first deformation block, periodically energizes the negative conductive plate of the second deformation block, and then the first deformation block deforms in the first direction, The second deformation block is deformed in the second direction, and the first direction is opposite to the second direction; in this case, the first deformation block will push the first telescopic cavity to move in the second direction, and the second deformation block will push the second telescopic cavity The cavity moves in the first direction, the first telescopic cavity drives the first gear to rotate counterclockwise through the first connecting rod, and the second telescopic cavity drives the second gear to rotate clockwise through the second connecting rod, thereby driving the bendable area to flatten , so that the middle frame and foldable display switch to the unfolded state.

In the same principle, when the middle frame is in the unfolded state, if a click operation acting on the designated virtual key of the electronic device is received, the processor inputs a second electrical signal to the drive module, for example, the processor periodically deforms the first The negative conductive plate of the block is energized, and the negative conductive plate of the second deformation block is energized, so that the middle frame and the foldable display screen can be switched to the folded state. The specific connection relationship and implementation principle among the above hardware structures such as the first deformation block, the first telescopic rod, and the first telescopic cavity can be referred to the descriptions in the foregoing electronic device embodiments, which will not be repeated in this embodiment.

According to the solution provided by the embodiment of the present application, the electronic device can control the movement of the telescopic mechanism in response to the first input in response to the first input to drive the bendable area to bend, so that the electronic device is in a folded state and a moving state switch between. In this way, electric control is also realized for the folding or unfolding of the electronic device. Compared with the existing manual folding or unfolding that requires the user to hold both sides of the electronic device, the embodiment of the present application avoids such labor-intensive and labor-intensive operation, and the degree of folding or unfolding of the electronic device can be a preset degree, which is no longer the subjective judgment of the user's manual folding, and can also avoid the screen damage caused by the user's excessive folding or excessive force, and further Ensure the reliability and safety of electronic equipment.
