Embodiments of the present application are described below with reference to the accompanying drawings.

Please refer to fig. 1, which is a schematic cross-sectional view illustrating a foldable electronic device in a half-open state according to an embodiment of the present application. The foldable electronic device 100 may be any foldable electronic device such as a smart phone, a tablet computer, a Personal Digital Assistant (PDA), a point of sale (POS), a notebook computer, and the like, which is not limited in this embodiment.

As shown in fig. 1, in the embodiment of the present application, a foldable electronic device 100 is described by taking a foldable mobile phone as an example. The foldable electronic device 100 includes a first cover 10, a second cover 20, and a hinge 30. The shaft 30 is rotatably connected between the first cover 10 and the second cover 20. In the present embodiment, the first cover 10 is a top cover assembly of the foldable electronic device 100, and the second cover 20 is a bottom cover assembly of the foldable electronic device 100, but not limited thereto, in other embodiments, the first cover 10 may be a bottom cover assembly of the foldable electronic device 100, and the second cover 20 may be a top cover assembly of the foldable electronic device 100.

Under the action of the rotating shaft 30, the first cover 10 and the second cover 20 can be folded to a closed state and unfolded to an open state. When the first cover 10 and the second cover 20 are in the closed state, the frame of the first cover 10 and the frame of the second cover 20 are partially overlapped or completely overlapped.

Referring to fig. 2 and fig. 3, fig. 2 is a schematic cross-sectional view of the foldable electronic device 100 in fig. 1 in a closed state; fig. 3 is a schematic cross-sectional view of the foldable electronic device 100 in fig. 1 in an opened state. When the foldable electronic device 100 is in the closed state, the first cover 10 and the second cover 20 are attached to each other, that is, an included angle between the first cover 10 and the second cover 20 is 0 degree; when the foldable electronic device 100 is in the open state, the first cover 10, the second cover 20 and the hinge 30 are on the same plane, that is, an included angle between the first cover 10 and the second cover 20 is 180 degrees; when the included angle between the first cover 10 and the second cover 20 is greater than 0 degree and smaller than 180 degrees, the foldable electronic device 100 is in a half-open state.

Referring to fig. 1-3, in the embodiment of the present application, the foldable electronic device 100 further includes a flexible display 40. The first cover 10 is used to carry a portion of the flexible display 40, and the second cover 20 is used to carry another portion of the flexible display 40. The flexible display screen comprises a display surface and a non-display surface which are oppositely arranged. The non-display surface is bonded to the first cover 10 and the second cover 20. When the foldable electronic device 100 is in the closed state, the display surfaces of the flexible display screens 40 are close and attached to each other; when the foldable electronic device 100 is in the open state, the display surface of the flexible display 40 is a horizontal surface for the user to use.

In the embodiment of the present application, the flexible display 40 may be an Organic light-Emitting Diode (O L ED) display, which has the characteristics of being bendable, twistable, and foldable, and has better color and contrast, and being ultra-thin, in other embodiments, the flexible display 40 may also be other types of flexible displays, such as a quantum dot display.

In the embodiment of the present application, the foldable electronic device 100 further includes a first magnetic member 50, a second magnetic member 60, and a driving assembly 70. The first magnetic member 50 and the driving assembly 70 are disposed in the first cover 10, and the driving assembly 70 is connected to the first magnetic member 50. The second magnetic member 60 is disposed on the second cover 20. When the foldable electronic device 100 is in the closed state, the first magnetic member 50 and the second magnetic member 60 are in the first relative position and attract each other. When the electronic device 100 receives a trigger instruction from a user during folding, the driving assembly 70 drives the first magnetic member 50 to move relative to the second magnetic member 60 to a second relative position, so that the first magnetic member 50 and the second magnetic member 60 repel each other, and further the first cover 10 and the second cover 20 are separated by the repulsive force. In this manner, the foldable electronic device 100 can be automatically opened.

In the foldable electronic device 100 in the embodiment of the present application, the first magnetic member 50 and the driving assembly 70 are disposed in the first cover 10, and the second magnetic member 60 is disposed in the second cover 20, so that the relative positions of the first magnetic member 50 and the second magnetic member 60 can be changed to change the first magnetic member 50 and the second magnetic member 60 from the attraction state to the repulsion state, thereby achieving the purpose of automatic opening, avoiding manual opening, and facilitating the operation of a user.

Referring to fig. 4 and 5, fig. 4 is a schematic structural diagram of the driving assembly, the first magnetic member and the second magnetic member in a first state; fig. 5 is a schematic structural diagram of the driving assembly, the first magnetic member and the second magnetic member in a second state. The driving assembly 70 includes a driving shaft 71, a shaft seat 72 and a driving spring 73. The drive shaft 71 is mounted on the shaft seat 72 and is movable relative to the shaft seat 72. One end of the driving shaft 71 extends out of the shaft seat 72 and is fixedly connected with the first magnetic member 50. The driving spring 73 is sleeved on the driving shaft 71 and is used for driving the driving shaft 71 to move relative to the shaft seat 72, so as to drive the first magnetic member 50 to move relative to the second magnetic member 60, and thus the first magnetic member 50 and the second magnetic member 60 are switched from the first relative position (see fig. 4) to the second relative position (see fig. 5). Wherein the directions of arrows in fig. 4 and 5 represent the directions of the forces generated by the first and second

magnetic members

50 and 60, respectively.

In one embodiment, the first magnetic member 50 is slidably connected to the first cover 10. For example, the first magnetic member 50 and the first cover 10 may be slidably connected by a sliding rail or a sliding groove. The second magnetic member 60 is relatively fixedly connected to the second cover 20. In this way, the first magnetic member 50 can move relative to the second magnetic member 60 under the action of the driving spring 73.

Specifically, the shaft seat 72 includes a first fixed end 721 and a second fixed end 722 spaced apart from each other. The driving shaft 71 passes through the first and second fixed ends 721 and 722 in turn and is movable relative to the first and second fixed ends 721 and 722. The first magnetic member 50 is mounted on one end of the driving shaft 71 and is located on a side of the second fixed end 722 far away from the first fixed end 721. The driving spring 73 is disposed on the driving shaft 71 and located between the first fixed end 721 and the second fixed end 722.

In one embodiment, in order to achieve a better driving of the first magnetic member 50, the driving shaft 71 is convexly provided with a supporting portion 711, and the supporting portion 711 is located between the first fixing end 721 and the second fixing end 722. The driving spring 73 is located between the first fixing portion 721 and the abutting portion 711. When the driving spring 73 is deformed, a driving force is generated to push the supporting portion 711 to move toward the second fixed end 722, so as to drive the driving shaft 71 to move relative to the shaft seat 72.

In one embodiment, the driving assembly 70 further includes a balance spring 74 for adjusting the driving force provided by the driving spring 73 to ensure the moving speed of the first magnetic member 50. The balance spring 74 is sleeved on the driving shaft 71 and located between the abutting portion 711 and the second fixing portion 722. Thus, when the driving spring 73 drives the driving shaft 71 to move, the abutting portion 711 presses the balance spring 74, so that the balance spring 74 generates an abutting force opposite to the driving force, thereby enabling the driving shaft 71 to move smoothly and improving the performance of the product.

In one embodiment, to achieve more precise driving of the first magnetic element 50, the driving spring is a Shape Memory Alloy (SMA) spring. The SMA spring is deformed when receiving an electric signal, and then generates a driving force. In this embodiment, the SMA spring is deformed by elongation when receiving the electrical signal, and when the electrical signal disappears, the SMA spring recovers the deformation to drive the first magnetic member 50 to move relative to the second magnetic member 60, so that the first magnetic member 50 and the second magnetic member 60 are switched from the second relative position to the first relative position.

Referring to fig. 6 and 7, fig. 6 is a schematic diagram illustrating magnetic pole distributions of the first magnetic member and the second magnetic member at a first relative position; fig. 7 is a schematic view of the magnetic pole distribution of the first magnetic member and the second magnetic member in a second relative position. In one embodiment, in order to provide stronger attractive and repulsive forces, the number of the first magnetic members 50 is two or more, and the number of the second magnetic members 60 is also two or more. As shown in fig. 6, when the plurality of first magnetic members 50 and the plurality of second magnetic members 60 are in the first relative position, the plurality of first magnetic members 50 and the plurality of second magnetic members 60 are attracted to each other. As shown in fig. 7, when the plurality of first magnetic members 50 and the plurality of second magnetic members 60 are in the second relative position, the plurality of first magnetic members 50 and the plurality of second magnetic members 60 repel each other. In the present embodiment, the first magnetic member 50 and the second magnetic member 60 are both magnets. In other embodiments, the first magnetic member 50 and the second magnetic member 60 may also be other magnetic objects.

It is understood that the composition of the plurality of first magnetic members 50 and the plurality of second magnetic members 60 and the distribution of the magnetic poles shown in fig. 6 and 7 are merely an example, and in other embodiments, the number and polarity distribution of the first magnetic members 50 and the second magnetic members 60 are not limited thereto, as long as the first magnetic members 50 and the second magnetic members 60 are attracted to each other when in the first relative position and the first magnetic members 50 and the second magnetic members 60 are repelled from each other when in the second relative position.

In an embodiment, in order to provide a closing force better so that the foldable electronic device 100 is not easily opened when in the closed state, the first magnetic member 50 is disposed on a side of the first cover 10 away from the hinge 30, and the second magnetic member 60 is disposed on a side of the second cover 20 away from the hinge 30.

Please refer to fig. 8, which is a functional block diagram of the foldable electronic device 100. The foldable electronic device 100 further includes a detection module 80 and a processor 90. The processor 90 is electrically connected to the detection module 80 and the drive spring 73, respectively. The detection module 80 is used for detecting a trigger instruction of a user. The processor 90 is configured to send an electrical signal to the drive spring 73 upon determining that a user trigger command has been received. Specifically, the processor 90 is configured to determine that a trigger instruction of a user is received when the detection signal received by the processor 90 is the same as a preset detection signal when the detection signal generated by the detection module 80 is received, and the processor 90 generates an electrical signal and sends the electrical signal to the driving spring 73. The driving spring 73 is deformed according to the reception of the electric signal. For example, the driving spring 73 may be connected to a power source through an electronic switch (e.g., a mosfet), the processor 90 is electrically connected to the electronic switch and controls the electronic switch to be turned on and off, and when the processor 90 receives a trigger command, the processor 90 controls the electronic switch to be turned on, so that the power source can supply power to the driving spring 73.

The Processor 90 may be a Central Processing Unit (CPU), other general-purpose Processor, a Digital Signal Processor (DSP), an Application Specific Integrated Circuit (ASIC), a Field-Programmable Gate Array (FPGA) or other Programmable logic device, a discrete Gate or transistor logic device, a discrete hardware component, or the like. The general purpose processor may be a microprocessor or the processor may be any conventional processor or the like, the processor being the control center for the foldable electronic device 100 and connecting the various parts of the entire foldable electronic device 100 using various interfaces and wires.

Several ways of detecting a user-triggered instruction are described below.

Referring to fig. 9, in one embodiment, the detection module 80 is a pressure sensor. The pressure sensor is disposed at a side of the first cover 10 or the second cover 20, and generates a detection signal when the pressure sensor detects a pressure applied by a user. When the pressure signal generated by the pressure sensor is the same as the preset pressure signal, the processor 90 determines that the triggering instruction of the user is received, and sends an electrical signal to the driving spring 73, so that the driving spring 73 is deformed to drive the first magnetic member 50 to move relative to the second magnetic member 60. In this embodiment, when the user holds the foldable electronic device 100, the user can generate a trigger command to separate the first cover 10 from the second cover 20.

In one embodiment, in order to improve the generation accuracy of the detection signal and facilitate the user operation, the foldable electronic device 100 includes two pressure sensors, and the two pressure sensors are respectively disposed on two opposite sides of the first cover 10 or the second cover 20.

Referring to fig. 10, in one embodiment, the detecting module 80 is a touch screen. The touch screen is disposed on a side of the first cover 10 facing away from the second cover 20 (when the foldable electronic device 100 is in a folded state), and when the operation gesture received by the touch screen is the same as the preset operation gesture, the processor 90 determines that the trigger instruction of the user is received, and sends an electrical signal to the driving spring 73, so that the driving spring 73 deforms.

Referring to fig. 11, in one embodiment, the detecting module 80 is a fingerprint sensor. The fingerprint sensor is disposed on the first cover 10, and when the fingerprint received by the fingerprint sensor is the same as the preset fingerprint, the processor 90 determines that the trigger command of the user is received, and sends an electrical signal to the driving spring 73, so that the driving spring 73 deforms.

Referring to fig. 12, in one embodiment, the detection module 80 is a camera. The camera is disposed on a side of the first cover 10 facing away from the second cover 20 (when the foldable electronic device 100 is in a folded state), and when the portrait identified by the camera is the same as the preset portrait, the processor 90 determines that the triggering instruction of the user is received, and sends an electrical signal to the driving spring 73, so that the driving spring 73 is deformed.

In addition, in an embodiment, the detecting module 80 is a microphone, the microphone is disposed on the first cover 10, and when the sound information received by the microphone is the same as the preset sound information, the processor 90 determines that a triggering instruction of a user is received, and sends an electric signal to the driving spring 73, so as to deform the driving spring 73.

In the above embodiments, different trigger instructions corresponding to different detection modules 80 are described, and certainly, the trigger instruction of the user is not limited to the above embodiments. The user can set different trigger instructions according to actual use requirements. The above embodiments may exist alone or in combination, and are not limited herein.

The foldable electronic device 100 in the embodiment of the present application may utilize the existing detection module 80 (such as a fingerprint sensor, a camera, or a microphone) of the foldable electronic device 100 to detect the operation of the user, and send the detected signal to the processor 90, so that the processor 90 determines whether a trigger instruction of the user is received according to the detection signal, and sends an electrical signal to the driving spring 73. Thus, the user can customize the opening action, and the applicability of the folding electronic device 100 is improved.

The foregoing is an implementation of the embodiments of the present application, and it should be noted that, for those skilled in the art, several modifications and decorations can be made without departing from the principle of the embodiments of the present application, and these modifications and decorations are also regarded as the protection scope of the present application.
