The electronic device 10 may further include a sub-screen disposed on the first housing 110 or the second housing 120 and located on a side opposite to the display screen 30, and the sub-screen may be one or more, which is not limited in this embodiment.

With continued reference to fig. 1 and 2, the first frame 100 includes a first frame 110 disposed along a first direction X and third and fourth frames 130 disposed along a second direction Y, the third and fourth frames 120 and 130 are disposed opposite to each other, the first frame 110 is connected between the third and fourth frames 130, the second frame 200 includes a second frame 210 disposed along the first direction X and fifth and sixth frames 220 and 230 disposed along the second direction Y, the fifth and sixth frames 220 and 230 are disposed opposite to each other, and the second frame 210 is connected between the fifth and sixth frames 220 and 230.

The cavities formed in the first and second housings 100 and 200 may be provided with various other components such as a rear camera, an antenna, a processor, and the like.

The frame 20 further includes a magnetic attraction assembly 400, where the magnetic attraction assembly 400 includes a first magnetic element 410 and a second magnetic element 420, where the first magnetic element 410 is disposed on the first frame 100, and the second magnetic element 420 is disposed on the second frame 200, where a magnetic force may be generated between the first magnetic element 410 and the second magnetic element 420, and in some embodiments, the magnetic force may be an attractive force, and in some embodiments, a repulsive force. When the magnetic force is attractive, the magnetic force may drive the first and second housings 100 and 200 to approach each other and eventually fold toward each other, and when the magnetic force is repulsive, the magnetic force may drive the first and second housings 100 and 200 to separate from each other and eventually unfold relatively.

In some embodiments, referring to fig. 1 again, the first magnetic element 410 may be disposed at a portion of the first frame 100 adjacent to the first frame 110, and the second magnetic element 420 may be disposed at a portion of the second frame 200 adjacent to the first frame 110. In this way, the distance between the first magnetic member 410 and the second magnetic member 420 and the rotating shaft 300 can be increased, and the first frame 100 and the second frame 200 can be driven to rotate without generating a large moment when the first frame needs to be opened. In other embodiments, the first magnetic member 410 may be disposed at any other position of the first housing 100, and the second magnetic member 420 may be disposed at any other position of the second housing 200, which is not particularly limited in this embodiment.

As a more specific embodiment, referring to fig. 3, the first magnetic element 410 may be further disposed on the first frame 110 of the first frame 100, the second magnetic element 420 may be disposed on the second frame 210 of the second frame 200, and the first magnetic element 410 and the second magnetic element 420 may be disposed correspondingly, where the corresponding arrangement means that when the first frame 100 and the second frame 200 are folded, the first magnetic element 410 and the second magnetic element 420 of the magnetic assembly 400 are in an opposite state, and the first magnetic element 410 and the second magnetic element 420 have the largest magnetic force therebetween. Of course, it should be understood that in other embodiments, the first magnetic element 410 and the second magnetic element 420 may not be disposed completely corresponding to each other, and the first magnetic element 410 and the second magnetic element 420 of the magnetic assembly 400 may be partially opposite or staggered when the first frame 100 and the second frame 200 are folded. The first magnetic member 410 is disposed on the first frame 110, and the second magnetic member 420 is disposed on the second frame 210, so that the occupation of the internal space in the first frame 100 and the second frame 200 can be avoided, and the interference with other parts of the electronic device 10 can be prevented.

When in setting, the first frame 110 and the second frame 210 may be provided with a mounting groove for accommodating the first magnetic element 410 and the second magnetic element 420, where the first magnetic element 410 and the second magnetic element 420 may be completely or partially accommodated in the mounting groove.

It should be noted that, the first magnetic element 410 may be disposed on the third frame 120, and the second magnetic element 420 may be disposed on the fifth frame 220 correspondingly, and the first magnetic element 410 may be disposed on the fourth frame 130, and the second magnetic element 420 may be disposed on the sixth frame 230 correspondingly.

The housing 20 further includes a control device 500, where the control device 500 is configured to respond to an operation instruction of a user, in some embodiments, when the electronic apparatus 10 in an unfolded and folded state needs to be automatically implemented, as shown in fig. 4, the control device 500 may be configured to control the first magnetic member 410 and the second magnetic member 420 to repel each other, so as to drive the first housing 100 and the second housing 200 to unfold each other, for example, by controlling such that the first magnetic member 410 and the second magnetic member 420 generate a repulsive force, so as to drive the first housing 100 and the second housing 200 to unfold each other. In other embodiments, when it is desired to implement the electronic device 10 in an automated folded-unfolded state, the control device 500 may be configured to control the first magnetic member 410 and the second magnetic member 420 to attract each other to drive the first casing 100 and the second casing 200 to fold with each other. For example, the first and second frames 100 and 200 are driven to fold with each other by controlling such that the first and second magnetic members 410 and 420 generate attractive force.

The control device 500 may be a central processing unit, and is integrated on the motherboard and electrically connected to the first magnetic element 410 and/or the second magnetic element 420 to send a control command to the first magnetic element 410 and/or the second magnetic element 420. The control device 500 may also be electrically connected to the display screen to obtain an operation instruction of a user through the display screen, and control the first magnetic member 410 and/or the second magnetic member 420 in response to the operation instruction of the user. The operation instruction of the user may be sent through touch operation on the display screen, or may be sent through voice, or may be sent through an entity key set disposed on the frame of the electronic device 10, which is not limited in this embodiment.

In one embodiment, the electronic device 10 may further include a hall sensor (not shown) and a detection element matched with the hall sensor, where the detection element may be a magnet, and the hall sensor and the detection element are respectively disposed in the first frame 100 and the second frame 200 and are correspondingly disposed, and the hall sensor may be matched with the detection element to further detect a relative angle of the first frame 100 and the second frame 200. When a user applies a moment to the first housing 100 or the second housing 200 to relatively rotate the first housing 100 and the second housing 200, the relative angle of the first housing 100 and the second housing 200 may be changed, which means that the user may need to open the first housing 100 and the second housing 200 or close the first housing 100 and the second housing 200. The control device 500 may be electrically connected to the hall sensor to obtain a detection result of the hall sensor. The user can perform an operation of folding or unfolding the first and/or second housings 100 and 200 as an operation instruction. The user only needs to apply a slight moment to the electronic device 10, and at this time, the first housing 100 and the second housing 200 generate an angle change, and the hall sensor generates an operation instruction after detecting the angle change.

Specifically, when the hall sensor detects that the first housing 100 and the second housing 200 have a tendency to be large, it indicates that the user wants to open the electronic apparatus 10 in the folded state at this time, and when the hall sensor detects that the first housing 100 and the second housing 200 have a tendency to be small, it indicates that the user wants to fold the electronic apparatus 10 in the unfolded state at this time.

In a more specific embodiment, the second magnetic member 420 may be a permanent magnet, which may be, for example: neodymium iron boron (Nd) ₂ Fe ₁₄ B) Samarium cobalt (SmCo), alNiCo (AlNiCo), and the like. The control device 500 is used for controlling the first magnetic element 410 to generate a magnetic field or for controlling the first magnetic element 410 to generate a magnetic field, and when the first magnetic element 410 generates a magnetic field, the first magnetic element 410 and the second magnetic element 420 can attract each other or repel each other; when the magnetic field generated by the first magnetic member 410 is turned off, the magnetic force between the first magnetic member 410 and the second magnetic member 420 disappears.

In one embodiment, the first magnetic element 410 may be an electromagnet that generates a magnetic field when the electromagnet is energized and that the magnetic field generated by the first magnetic element 410 is removed, i.e., turned off, when the electromagnet is de-energized. The control device 500 may control the first magnetic element 410 to be powered on or powered off. In particular, referring to fig. 5, the electromagnet includes a core 411 and a plurality of coils 412 wound around the core 411, when the coils 412 are energized, the electromagnet generates a magnetic field and repels the second magnetic member 420, and when the coils 412 are de-energized, a magnetic force can be generated between the core 411 and the second magnetic member 420, and the core 411 and the second magnetic member 420 attract each other. The magnetic pole of the end of the second magnetic element 420 near the first magnetic element 410 may be an N pole or an S pole, and when the first magnetic element 410 generates a magnetic field, the magnetic pole of the end of the first magnetic element 410 near the second magnetic element 420 is an N pole or an S pole.

Therefore, when the electronic device 10 in the folded state needs to be opened, the control device 500 controls the first magnetic member 410 to be energized to generate a magnetic field, and at this time, the magnetic field generated by the electromagnet and the magnetic field generated by the second magnetic member 420 have the same polarity, and the first magnetic member 410 and the second magnetic member 420 generate repulsive force to repel each other, so as to drive the first frame 100 and the second frame 200 to rotate relatively, and further open the electronic device 10 in the folded state. When the electronic device 10 in the open state needs to be folded, the control device 500 controls the first magnetic element 410 to be powered off, at this time, the second magnetic element 420 and the core 411 generate attractive force, and the attractive force can be used to drive the first frame 100 and the second frame 200 to rotate relatively, so as to fold the electronic device 10 in the open state, and in the folded state, the first magnetic element 410 and the second magnetic element 420 can continuously maintain the attractive force, so that the electronic device 10 maintains the folded state.

It will be appreciated that when the attractive force generated by the first magnetic member 410 and the second magnetic member 420 is insufficient to drive the first frame 100 and the second frame 200 to fold from the unfolded state, the user may also bend the first frame 100 and the second frame 200 by himself or herself to fold the first frame 100 and the second frame 200. By the arrangement mode, a user does not need to manually operate the first frame 100 or the second frame 200 to open when opening the electronic device 10 in the folded state, and the operation convenience is improved. Meanwhile, when the electronic device 10 is in the folded state, the attractive force of the first frame 100 and the second frame 200 can be provided, so that the two can maintain the folded state.

Further, the control device 500 may further control the current direction of the coil 412 in the first magnetic element 410, further control the magnetic pole direction to be reversed, further change the direction of the force between the first magnetic element 410 and the second magnetic element 420, so that the acting force between the first magnetic element 410 and the second magnetic element 420 is switched from repulsive force to attractive force, or from attractive force to repulsive force. And further selectively controls the folding or unfolding of the first and second housings 100 and 200.

In another embodiment, the first magnetic member 410 may also employ a permanent magnet, and the control device 500 may "turn off" the magnetic field of the first magnetic member 410 by shielding the repulsive force between the first magnetic member 410 and the second magnetic member 420. For example, the control device 500 may include a control part 520 and a magnetic shield, which may be made of a plastic material, and the control part 520 may control the magnetic shield to move between the first magnetic member 410 and the second magnetic member 420 such that the magnetic shield between the first magnetic member 410 and the second magnetic member 420 is removed such that the repulsive force therebetween is eliminated. Specifically, the magnetic shield may be coupled to a cylinder to effect movement, and may move between the first magnetic member 410 and the second magnetic member 420 during movement to effect magnetic shielding.

It should be noted that the second magnetic member 420 may also be configured as an electromagnet, and have the same structure as the first magnetic member 410, and reference is made to the foregoing. At this time, the control device 500 may simultaneously control the power on or off of the first magnetic member 410 and the second magnetic member 420. The control device can also control the current direction of the coil 412 in the first magnetic element 410 and the second magnetic element 420, and further control the magnetic pole change, and further change the direction of the force between the first magnetic element 410 and the second magnetic element 420, and control the first frame 100 and the second frame 200 to fold or unfold.

In another embodiment, the magnetic attraction assemblies 400 may be multiple groups, and each group of magnetic attraction assemblies 400 includes a first magnetic member 410 and a second magnetic member 420, where the first magnetic member 410 and the second magnetic member 420 of the same group are disposed in the first frame 100 and the second frame 200. That is, when the first and second housings 100 and 200 are folded, the positions of the first magnetic members 410 and 420 in the same group are corresponding to the positions of the first and second housings 100 and 200. Each set of magnet assemblies 400 simultaneously generates an attractive force or simultaneously generates a repulsive force.

In the exemplary embodiment shown in fig. 6, the magnetic attraction assemblies 400 are three groups, the first magnetic members 410 of one group of magnetic attraction assemblies 400 are disposed on the first frame 110, and the second magnetic members 420 are disposed on the second frame 210; the first magnetic element 410 of the magnetic assembly 400 is disposed on the third frame 120, and the second magnetic element 420 is disposed on the fifth frame 220; the first magnetic members 410 of the magnetic attraction assemblies 400 are disposed on the fourth frame 130, the second magnetic members 420 are disposed on the sixth frame 230, and the three magnetic attraction assemblies 400 synchronously generate attraction force or synchronously generate repulsive force. By disposing the magnetic assembly 400 on the frames of the first frame 100 and the second frame 200, the space occupation of the magnetic assembly 400 inside the first frame 100 and the second frame 200 can be reduced, and the space occupied by other components of the electronic device 10 can be avoided.

By increasing the number of magnetic assemblies 400, the amount of repulsive or attractive force generated by magnetic assemblies 400 may be increased, and thus the driving force may be greater when opening or folding electronic device 10, and the efficiency of opening or folding may be improved. Of course, when the magnetic attraction assemblies 400 are in multiple groups, the first magnetic member 410 and the second magnetic member 420 may be disposed at other positions of the frame, for example, in the inner space of the first frame 100 or the inner space of the second frame 200.

Further, in another embodiment, the magnetic attraction assemblies 400 may be arranged in two groups, the first magnetic members 410 of the two groups of magnetic attraction assemblies 400 are arranged as electromagnets, and in the two groups of magnetic attraction assemblies 400, the magnetic poles of the first magnetic member 410 of the first group of magnetic attraction assemblies 400 near the second magnetic member 420 are the same as the magnetic poles of the second magnetic member 420 near the first magnetic member 410, and the magnetic poles of the first magnetic member 410 of the second group of magnetic attraction assemblies 400 near the second magnetic member 420 are different from the magnetic poles of the second magnetic member 420 near the first magnetic member 410.

When the electronic device 10 in the folded state needs to be controlled to be unfolded, the first magnetic members 410 of the first set of magnetic attraction assemblies 400 are controlled to be electrified, and the first magnetic members 410 of the second set of magnetic attraction assemblies 400 are powered off, so that the first frame 100 and the second frame 200 rotate to be unfolded. When the electronic device 10 in the folded state needs to be controlled to be folded, the first magnetic pieces 410 of the first set of magnetic attraction assemblies 400 are controlled to be powered off, and the first magnetic pieces 410 of the second set of magnetic attraction assemblies 400 are powered on, so that the first frame 100 and the second frame 200 are folded. Thus, folding and unfolding of the electronic device 10 may be accomplished automatically.

Referring to fig. 7 and 8, fig. 7 shows another embodiment in which the first magnetic member 410 is configured to be movable. During the movement of the first magnetic member 410, the magnitude and direction of the magnetic force generated between the first magnetic member 410 and the second magnetic member 420 may be changed, so that the relative movement between the first frame 100 and the second frame 200 may be controlled. It will be appreciated that in other embodiments, the second magnetic member 420 may be configured to be movable, and the control device 500 may also control the movement of the second magnetic member 420.

The magnetic pole of the end of the first magnetic member 410 near the second magnetic member 420 may be the same as or different from the magnetic pole of the end of the second magnetic member 420 near the first magnetic member 410, and when the magnetic poles are the same, the first magnetic member 410 and the second magnetic member 420 generate repulsive force, and when the magnetic poles are opposite, the first magnetic member 410 and the second magnetic member 420 generate attractive force.

When the magnetic pole of the end of the first magnetic member 410 near the second magnetic member 420 is the same as the magnetic pole of the end of the second magnetic member 420 near the first magnetic member 410, and the repulsive force generated between the first magnetic member 410 and the second magnetic member 420 is greater than the rotational resistance between the first frame 100 and the second frame 200, the first frame 100 and the second frame 200 can be driven to be spread apart from each other. When the magnetic pole of the first magnetic member 410 near the end of the second magnetic member 420 is opposite to the magnetic pole of the second magnetic member 420 near the end of the first magnetic member 410, the attractive force generated between the first magnetic member 410 and the second magnetic member 420 is greater than the rotational resistance between the first frame 100 and the second frame 200, and the first frame 100 and the second frame 200 are driven to fold with each other. Therefore, according to different design requirements, the magnetic pole setting directions of the first magnetic element 410 and the second magnetic element 420 can be adjusted, so as to realize the purposes of opening the electronic device 10 in the folded state or folding the electronic device 10 in the unfolded state.

For example: when the first magnetic member 410 and the second magnetic member 420 move to the positions corresponding to each other, the interaction force between the first magnetic member 410 and the second magnetic member 420 is maximized, and the repulsive force between the first magnetic member 410 and the second magnetic member 420 overcomes the rotation resistance between the first frame 100 and the second frame 200, so that the first frame 100 and the second frame 200 relatively rotate to the unfolded state. When the first magnetic member 410 and the second magnetic member 420 are moved to the positions where they are offset from each other, the interaction force between the first magnetic member 410 and the second magnetic member 420 is small, and the repulsive force between the first magnetic member 410 and the second magnetic member 420 is insufficient to overcome the rotation resistance between the first frame 100 and the second frame 200, so that the first frame 100 and the second frame 200 do not rotate relatively.

In particular, in the present embodiment, the second magnetic member 420 is configured in a fixed arrangement, that is, the position of the second magnetic member 420 does not change, and the force generated between the first magnetic member 410 and the second magnetic member 420 is a repulsive force. The control device 500 is configured to drive the first magnetic member 410 to move in response to an operation instruction of a user, and change a force between the first magnetic member 410 and the second magnetic member 420 during the movement, and drive the first frame 100 and the second frame 200 to be mutually expanded when the force between the first magnetic member 410 and the second magnetic member 420 is greater than a rotational resistance between the first frame 100 and the second frame 200.

Specifically, the first magnetic element 410 is a permanent magnet, as shown in fig. 8, the control device 500 includes a driving part 510 and a control part 520, the driving part 510 is connected to the first magnetic element 410 and is used for driving the first magnetic element 410 to move, the control part 520 is used for responding to an operation instruction of a user and controlling the driving part 510 to be started or closed, the driving part 510 can be, for example, a telescopic cylinder, a motor-driven screw rod, and the like, and when the driving part 510 is started, the first magnetic element 410 is driven and moves along the telescopic direction of the driving part 510, and in the process, the acting force between the first magnetic element 410 and the second magnetic element 420 is changed. In this embodiment, the magnetic pole of the end of the first magnetic member 410 near the second magnetic member 420 is the same as the magnetic pole of the end of the second magnetic member 420 near the first magnetic member 410, and when the first magnetic member 410 moves to the position corresponding to the second magnetic member 420, the two generate repulsive force.

Further, the first magnetic element 410 may be disposed on the first frame 110, the first frame 110 may be provided with a receiving groove, the first magnetic element 410 and the driving portion 510 are disposed in the receiving groove, the receiving groove extends for a certain length along the axial direction of the rotating shaft 300, so that the first magnetic element 410 can move along the axial direction of the rotating shaft 300, and the receiving groove has an area corresponding to the position of the second magnetic element 420 and an area offset from the position of the second magnetic element 420, so that the first magnetic element 410 can correspond to the second magnetic element 420 or can be offset from the second magnetic element 420 in the moving process.

The driving portion 510 is configured to drive the first magnetic member 410 to move along the axial direction of the rotating shaft 300 to change the acting force between the first magnetic member 410 and the second magnetic member 420, and in other embodiments, the moving direction of the driving portion 510 to drive the first magnetic member 410 may be other directions, which is not limited in this embodiment. In the above embodiment, the first magnetic member 410 is controlled to move, so as to change the acting force between the first magnetic member 410 and the second magnetic member 420, so as to realize the folding or unfolding of the first frame 100 and the second frame 200, and the magnetic poles of the first magnetic member 410 and the second magnetic member 420 are adjusted according to different design requirements, so that the purpose of unfolding or folding can be realized.

Further, in another embodiment, the magnetic attraction assemblies 400 may be arranged in two groups, the first magnetic members 410 of the two groups of magnetic attraction assemblies 400 are movably arranged, and in the two groups of magnetic attraction assemblies 400, the magnetic pole of the first magnetic member 410 of the first group of magnetic attraction assemblies 400 near the second magnetic member 420 is the same as the magnetic pole of the second magnetic member 420 near the first magnetic member 410, and the magnetic pole of the first magnetic member 410 of the second group of magnetic attraction assemblies 400 near the second magnetic member 420 is different from the magnetic pole of the second magnetic member 420 near the first magnetic member 410.

When the electronic device 10 in the folded state needs to be controlled to be unfolded, the first magnetic members 410 of the first set of magnetic attraction assemblies 400 are controlled to move to correspond to the second magnetic members 420, and the first magnetic members 410 of the second set of magnetic attraction assemblies 400 are moved to be staggered from the second magnetic members 420, so that the first frame 100 and the second frame 200 rotate to be unfolded. When the electronic device 10 in the folded state needs to be controlled to be folded, the first magnetic pieces 410 of the first set of magnetic attraction assemblies 400 are controlled to be shifted from the second magnetic pieces 420, and the first magnetic pieces 410 of the second set of magnetic attraction assemblies 400 are controlled to be shifted to correspond to the second magnetic pieces 420, so that the first frame 100 and the second frame 200 are folded.

Thus, the control device 500 can control the different magnetic modules 400 to fold the first and second housings 100 and 200 when folding is required and to open the first and second housings 100 and 200 when opening is required.

Wherein the control 520 may be a processor integrated on a motherboard, the processor may include one or more processing cores. The processor uses various interfaces and lines to connect various portions of the overall electronic device 10, perform various functions of the electronic device 10, and process data by executing or executing instructions, programs, code sets, or instruction sets stored in memory, and invoking data stored in memory. Alternatively, the processor may be implemented in hardware in at least one of digital signal processing (Digital Signal Processing, DSP), field programmable gate array (Field-Programmable Gate Array, FPGA), programmable logic array (Programmable Logic Array, PLA). The processor may integrate one or a combination of several of a central processing unit (Central Processing Unit, CPU), an image processor (Graphics Processing Unit, GPU), and a modem etc. The CPU mainly processes an operating system, a user interface, an application program and the like; the GPU is used for being responsible for rendering and drawing of display content; the modem is used to handle wireless communications.
