Description
Technical Field
The application belongs to the technical field of communication, and particularly relates to an electronic device.
Background
With the extreme pursuit of the user for the use experience, the foldable electronic device is greatly favored by the user due to the advantages of larger display area and smaller storage volume. A foldable electronic device generally includes a first body and a second body that are foldable relative to each other, and the first body and the second body may be connected by a hinge to switch between an unfolded state and a folded state.
In the prior art, in order to enable the first body and the second body to achieve the folded state and maintain the folded state, a magnetic attraction piece or a buckle piece is generally required to be respectively arranged on the first body and the second body, so that the first body and the second body can achieve the folded state and maintain the folded state.
However, when the electronic device needs to be switched from the folded state to the unfolded state, the first body and the second body need to be opened with a large force regardless of the magnetic-type or snap-type fastening manner, which greatly reduces the user experience of the foldable electronic device.
Disclosure of Invention

In order to solve the technical problem, the present application is implemented as follows:
the application discloses electronic equipment, electronic equipment includes: the magnetic shielding device comprises a first body, a second body, a magnetic shielding piece and a driving mechanism; wherein,
the first body is rotatably connected with the first body to realize switching between an unfolded state and a folded state;
the first body is provided with a first magnetic piece, the second body is provided with a second magnetic piece, and the first magnetic piece and the second magnetic piece are opposite and magnetically adsorbed in the folded state;
the magnetic isolation piece is arranged in the first body or the second body, the driving mechanism is connected with the magnetic isolation piece, and the driving mechanism is used for driving the magnetic isolation piece to move;
in the folded state, in response to the unfolding operation, the driving mechanism may drive the magnetism isolating member to move to between the first magnetic member and the second magnetic member, and release the magnetic attraction between the first magnetic member and the second magnetic member.
In the embodiment of the application, a magnetism isolating piece and a driving mechanism may be disposed in the first body or the second body of the electronic device, and the driving mechanism may control the movement of the magnetism isolating piece. When the electronic device is in the folded state, in response to an unfolding operation, the driving mechanism can drive the magnetism isolating piece to move to a position between the first magnetic piece and the second magnetic piece, and magnetic adsorption between the first magnetic piece and the second magnetic piece is released. Thus, the first magnetic member and the second magnetic member no longer have a magnetic attraction force capable of holding the folded state. The user can open the first body and the second body with small effort, and the use experience of the user on the electronic equipment is greatly improved.

The embodiment of the present application provides an electronic device, where the electronic device may include but is not limited to at least one of a mobile phone, a tablet computer, and a wearable device, and a specific type of the electronic device may not be limited in the embodiments of the present application.
Referring to fig. 1, a schematic mechanism diagram of an electronic device according to an embodiment of the present application is shown, and referring to fig. 2, a schematic structural diagram of a part of components of the electronic device shown in fig. 1 is shown.
Specifically, the electronic device may specifically include: a first body 10, a second body 20, a magnetic shielding member 50, and a driving mechanism 60; wherein,
the first body 10 and the first body 10 are rotatably connected to switch between the unfolded state and the folded state;
the first body 10 is provided with a first magnetic part 101, the second body 20 is provided with a second magnetic part 201, and in the folded state, the first magnetic part 101 and the second magnetic part 201 are opposite and magnetically attracted;
the magnetic isolation piece 50 is arranged in the first body 10 or the second body 20, the driving mechanism 60 is connected with the magnetic isolation piece 50, and the driving mechanism 60 can be used for driving the magnetic isolation piece 50 to move;
in the folded state, in response to the unfolding operation, the driving mechanism 60 may drive the magnetism isolating member 50 to move between the first magnetic member 101 and the second magnetic member 201, and release the magnetic attraction between the first magnetic member 101 and the second magnetic member 201.
In the embodiment of the present application, the first body 10 or the second body 20 of the electronic device may be provided with a magnetic isolation member 50 and a driving mechanism 60, and the driving mechanism 60 may control the magnetic isolation member 50 to move. In the folded state of the electronic device, in response to the unfolding operation, the driving mechanism 60 may drive the magnetic isolation member 50 to move between the first magnetic member 101 and the second magnetic member 201, and release the magnetic attraction between the first magnetic member 101 and the second magnetic member 201. Thus, the magnetic attraction force capable of holding the folded state is no longer provided between the first magnetic member 101 and the second magnetic member 201. The user can open the first body 10 and the second body 20 with only small effort, and the use experience of the user on the electronic device is greatly improved.
Specifically, the electronic device may further include a hinge 20 and a flexible screen 40, wherein the hinge 30 is located between the first body 10 and the second body 20; the flexible screen 40 is disposed on the first body 10 and the second body 20. The first body 10 and the second body 20 may serve as structural bodies in the electronic device for supporting the flexible screen 40 and various functional components of the electronic device. The first body 10 and the second body 20 may be connected by a hinge 30, and at least one of the first body 10 and the second body 20 is rotatably connected with the hinge 30 to enable switching between the unfolded state and the folded state. In the unfolded state, the flexible screen 40 can be unfolded to form an integral screen, and the display area is large. In the folded state, the first body 10 and the second body 20 may be folded relatively to reduce the volume of the electronic device, so as to facilitate carrying the electronic device. In practical application, a user can switch the electronic device between the unfolded state and the folded state according to actual needs, so that the use experience of the user on the electronic device is improved.
In the embodiment of the present application, the first body 10 is provided with the first magnetic member 101, and the second body 20 is provided with the second magnetic member 201, in the folded state, the first magnetic member 101 is opposite to the second magnetic member 201 and magnetically attracted. The magnetic attraction between the first magnetic member 101 and the second magnetic member 201 can overcome the tension of the hinge 30 and the flexible screen 40, so that the electronic device can be maintained in the folded state.
For example, the first magnetic member 101 and the second magnetic member 201 may be a ferromagnetic member such as a magnet, magnetic steel, or an electromagnetic member, and the specific form of the first magnetic member 101 and the second magnetic member 201 in the embodiment of the present application may not be limited.
In the embodiment of the present application, a magnetism isolating member 50 is further disposed in the electronic device, and the magnetism isolating member 50 may be made of a magnetic shielding material to play a role in shielding a magnetic field.
Illustratively, the magnetic shielding material may have a magnetic permeability of from 200 to 350000. The magnetic shielding material may include any one of a high magnetic permeability material, a medium magnetic permeability material, and a high saturation material. The magnetic permeability of the high-permeability material is 80000-350000, the saturation field of the high-permeability material after heat treatment can reach 7500Gs, the magnetic permeability value of the medium-permeability material is 12500-150000, the saturation field is 15500Gs, the magnetic permeability value of the high-saturation permeability material is 200-50000, and the saturation field can reach 18000-21000 Gs. The embodiment of the present application does not specifically limit the magnetic shield material
Alternatively, the magnetism isolating member 50 may include at least one of a silicon steel sheet, ferrite, and nanocrystal. The silicon steel sheet is a ferrosilicon soft magnetic alloy with extremely low carbon content, and the silicon content is 0.5-4.5%. Under the condition that the magnetic isolation piece 50 is a silicon steel sheet, the magnetic field shielding effect can be realized, and the magnetic field shielding device has the advantages of easiness in realization and lower cost. The ferrite is a composite oxide with iron oxide and other iron group or rare earth group oxides as main components, and the ferrite is a semiconductor, and the resistivity of the ferrite is far greater than that of a common metal magnetic material. The nanocrystalline is a water-insoluble nanoscale crystal produced by packing calcium ions, magnesium ions, bicarbonate radicals and the like in water by using a high-energy polymeric sphere, so that the water is not scaled and the aim of softening is fulfilled. The magnetic shield 50 made of ferrite or nanocrystal has an effect of shielding a magnetic field.
In the embodiment of the present application, the magnetism isolating member 50 may be movably connected in the first body 10 or the second body 20, and the magnetism isolating member 50 may be moved between the first magnetic member 101 and the second magnetic member 201 or moved away from between the first magnetic member 101 and the second magnetic member 201 by the driving mechanism 60. In the case where the first magnetic member 101 is located between the first magnetic member 101 and the second magnetic member 201, the magnetism isolating member 50 may shield the magnetic field between the first magnetic member 101 and the second magnetic member 201, and release the attraction connection between the first magnetic member 101 and the second magnetic member 201.
For example, the magnetic shielding member 50 and the driving mechanism 60 may be both disposed in the first body 10, or the magnetic shielding member 50 and the driving mechanism 60 may be both disposed in the second body 20, or the magnetic shielding member 50 and the driving mechanism 60 may be both disposed in the first body 10 and the second body 20, and the specific positions of the magnetic shielding member 50 and the driving mechanism 60 may not be limited in the embodiments of the present application.
In some optional embodiments of the present application, the electronic device may further include a control module and a sensing module, where the sensing module is configured to obtain a deployment operation of a user on the electronic device. The control module may be electrically connected to the sensing module and the driving mechanism 60 to obtain the unfolding operation, and control the driving mechanism 60 to drive the magnetic shielding member 50 to perform related operations according to the unfolding operation.
In this embodiment, when the electronic device is in the folded state, the control module may acquire an unfolding operation of the user on the electronic device. In a case where the acquired expansion operation matches a prestored target operation, it may be considered that the user has a need to switch the electronic device to the expansion state. At this time, the control module may control the driving mechanism 60 to drive the magnetic isolation member 50 to move between the first magnetic member 101 and the second magnetic member 201 in response to the unfolding operation, and release the magnetic attraction between the first magnetic member 101 and the second magnetic member 201, so that the magnetic attraction capable of maintaining the folded state is no longer provided between the first magnetic member 101 and the second magnetic member 201. Under the effect of the tension of hinge 30 and flexible screen 40, electronic equipment hardly keeps fold condition, certain angle can be opened to first body 10 and second body 20 automatic bullet, and the user of being convenient for only needs little strength can open first body 10 and second body 20, and the user of very big improvement is right electronic equipment's use is experienced.
Accordingly, when the electronic device is in the unfolded state, in order to enable the first magnetic member 101 and the second magnetic member 201 to have a magnetic attraction function, the control module may control the magnetic isolation member 50 to leave a position between the first magnetic member 101 and the second magnetic member 201, so as to avoid the magnetic isolation member 50 from affecting the magnetic attraction between the first magnetic member 101 and the second magnetic member 201.
For example, the unfolding operation may be a tapping operation or a touch operation of a user on the first body 10 and/or the second body 20, and the specific content of the unfolding operation may not be limited in the embodiment of the present application.
For example, the control module may be a central processing unit of the electronic device and a control circuit used in cooperation with the central processing unit, or the control module may also be a separate chip specially used for controlling the driving mechanism 60, and the specific content of the control module in the embodiment of the present application may not be limited.
In an alternative embodiment of the present application, the magnetic shielding member 50 may comprise a magnetic shielding tape rotatably connected to the driving mechanism 60, and in the folded state, the driving mechanism 60 may drive the magnetic shielding tape to rotate between the first magnetic member 101 and the second magnetic member 201 in response to the unfolding operation.
Specifically, the driving mechanism 60 may drive the magnetic separator to rotate between the first magnetic member 101 and the second magnetic member 201, or to move away from between the first magnetic member 101 and the second magnetic member 201. Due to the flexible characteristic of the magnetic isolation tape, the space occupied by the magnetic isolation tape is small, and the arrangement of the magnetic isolation tape inside the electronic device is facilitated.
Referring to fig. 3, a schematic structural diagram of a magnetic isolation tape according to an embodiment of the present application is shown, and as shown in fig. 3, the magnetic isolation tape may specifically include a magnetic isolation portion 501 and a non-magnetic isolation portion 502 that are connected to each other; in the folded state, in response to the unfolding operation, the driving mechanism 60 may drive the magnetism isolating part 501 of the magnetism isolating tape to rotate between the first magnetic member 101 and the second magnetic member 201; in the expanded state, the driving mechanism 60 may drive the non-magnetic shielding portion 502 of the magnetic shielding tape to rotate between the first magnetic member 101 and the second magnetic member 201.
Specifically, the magnetic tape separating body can be made of flexible materials such as plastic and nylon. The magnetic shielding material is provided on the magnetic shielding tape body, so that the magnetic shielding portion 501 can be formed, and the magnetic shielding portion 501 has a function of shielding a magnetic field, so that when the magnetic shielding portion 501 is rotated between the first magnetic material 101 and the second magnetic material 201, magnetic attraction between the first magnetic material 101 and the second magnetic material 201 can be released. The non-magnetic-shielding portion 502 can be formed on the portion of the magnetic-shielding body where the magnetic-shielding material is not disposed, the non-magnetic-shielding portion 502 does not have a function of shielding a magnetic field, and when the non-magnetic-shielding portion 502 is rotated to a position between the first magnetic member 101 and the second magnetic member 201, the magnetic field generated by the first magnetic member 101 or the second magnetic member 201 can penetrate through the non-magnetic-shielding portion 502, that is, the non-magnetic-shielding portion 502 does not affect the magnetic attraction between the first magnetic member 101 and the second magnetic member 201.
In the embodiment of the present application, in the folded state, in response to the unfolding operation, the driving mechanism 60 may drive the magnetism isolating portion 501 of the magnetism isolating tape to rotate to between the first magnetic member 101 and the second magnetic member 201, so as to release the attraction connection between the first magnetic member 101 and the second magnetic member 201. In the unfolded state, the driving mechanism 60 can drive the non-magnetism-isolating part 502 of the magnetism isolating tape to rotate to a position between the first magnetic member 101 and the second magnetic member 201, so that the influence of the magnetism isolating part 501 on the magnetism isolating tape on the magnetic adsorbing tape between the first magnetic member 101 and the second magnetic member 201 is avoided, and the first magnetic member 101 and the second magnetic member 201 can keep the function of magnetic adsorption.
In practical applications, the area of the magnetic shield 501 and the area of the non-magnetic shield 502 in the magnetic shield tape may be set according to actual conditions. For example, the magnetic shield 501 and the non-magnetic shield 502 may each occupy half the area. For another example, the area of the magnetic shield 501 is three-quarters of the area of the magnetic shield tape, and the area of the non-magnetic shield 502 is one-quarter of the area of the magnetic shield tape. In the embodiment of the present application, the area ratio between the magnetic shield 501 and the non-magnetic shield 502 is not particularly limited.
Optionally, the magnetic shielding member 50 may further include a plurality of fixed shafts 503 disposed around the second magnetic member 201, and the magnetic shielding tape may be wound around the fixed shafts 503 to form a structure disposed around the second magnetic member 201; the driving mechanism 60 is connected to one of the plurality of fixing shafts 503, the driving mechanism 60 may be configured to drive the fixing shaft 503 to rotate, and the rotation of the fixing shaft 503 may drive the magnetic isolation belt to rotate.
Specifically, the magnetic isolation member 50 may further include a plurality of fixing shafts 503, and the fixing shafts 503 may be configured to support the magnetic isolation tape and drive the magnetic isolation tape to rotate. A plurality of fixing shafts 503 may be disposed around the second magnetic member 201, and the magnetic shielding tape may be wound around the fixing shafts 503, so that the magnetic shielding tape may be disposed around the second magnetic member 201.
In this embodiment, the driving mechanism 60 may be connected to one of the plurality of fixed shafts 503, the driving mechanism 60 is configured to drive the fixed shaft 503 connected thereto to rotate, and the rotation of the fixed shaft 503 may drive the magnetic isolation strip and the other fixed shaft 503 to rotate, so that the magnetic isolation part 501 or the non-magnetic isolation part 502 of the magnetic isolation strip is located between the first magnetic element 101 and the second magnetic element 201. In practical applications, the fixed shaft 503 connected to the driving mechanism 60 may be used to serve as a driving shaft, and the fixed shaft 503 not connected to the driving mechanism 60 may be used to serve as a driven shaft.
In practical applications, since the magnetism isolating band is disposed around the second magnetic member 201, the magnetism isolating portion 501 or the non-magnetism isolating portion 502 on the magnetism isolating band can be rotated between the first magnetic member 101 and the second magnetic member 201 by driving the magnetism isolating band to rotate around the second magnetic member 201 in one direction by the driving mechanism 60. Thus, the structure of the driving mechanism 60 can be made simple and the cost can be made low.
For example, the number and specific position of the fixing shafts 503 may be set according to the shape of the second magnetic member 201. For example, in the case where the second magnetic member 201 is a rectangular magnetic member, the number of the fixing shafts 503 may be 4, and the 4 fixing shafts 503 may be disposed at the top corners of the second magnetic member 201. For another example, in the case that the second magnetic member 201 is a triangular magnetic member, the number of the fixing shafts 503 may be 3, and the 3 fixing shafts 503 may be disposed at the vertex positions of the second magnetic member 201. The number and specific positions of the fixing shafts 503 in the embodiment of the present application may not be limited.
In an optional embodiment of the present application, the electronic device may further include: the position detection device 70, the position detection device 70 may specifically include a sensing element 702 and a triggering element 701 which are used in cooperation; wherein, the trigger 701 is connected with the magnetic isolation strip; the control module is connected with the induction piece 702, when the trigger piece 701 moves to a target position, the induction piece 702 can be triggered by the trigger piece 701 to generate an induction signal, and the driving mechanism 60 can stop driving the magnetism isolating belt to move in response to the induction signal; the target position is a position corresponding to the trigger 701 when the non-magnetic-shielding portion 502 is located between the first magnetic member 101 and the second magnetic member 201.
Specifically, the position detecting device 70 may be configured to determine whether a portion of the magnetic shielding tape located between the first magnetic member 101 and the second magnetic member 201 is a magnetic shielding portion 501 or a non-magnetic shielding portion 502. When the magnetic isolation portion 501 is located between the first magnetic member 101 and the second magnetic member 201, the triggering member 701 cannot trigger the sensing member 702, and when the non-magnetic isolation portion 502 is located between the first magnetic member 101 and the second magnetic member 201, the triggering member 701 can trigger the sensing member 702.
In practical applications, in response to the unfolding operation when the electronic device is in the folded state, the driving mechanism 60 may drive the magnetism isolating belt to rotate around the second magnetic member 201, and in the case that the magnetism isolating portion 501 of the magnetism isolating belt rotates between the first magnetic member 101 and the second magnetic member 201, the triggering member 701 moving along with the magnetism isolating belt may not trigger the sensing member 702. At this time, the driving mechanism 60 may keep driving the magnetic tape to rotate, and release the magnetic attraction between the first magnetic member 101 and the second magnetic member 201, so that the first body 10 and the second body 20 automatically spring out by a certain angle, which is convenient for a user to open the first body 10 and the second body 20, and greatly improves the user experience of the user for the electronic device.
Specifically, when the driving mechanism 60 drives the non-magnetism isolating part 502 of the magnetism isolating band to rotate between the first magnetic member 101 and the second magnetic member 201, the triggering member 701 moving along with the magnetism isolating band may correspondingly move to a target position capable of triggering the sensing member 702. At this time, the triggering component 701 may trigger the sensing component 702 to generate a sensing signal. The control module may control the driving mechanism 60 to stop driving the magnetic tape in rotation in response to the sensing signal generated by the sensing member 702, so that the non-magnetic-shielding portion 502 of the magnetic tape may be held between the first magnetic member 101 and the second magnetic member 201. Since the non-magnetic shielding portion 502 of the magnetic shielding tape does not have the function of shielding the magnetic field, the magnetic field between the first magnetic member 101 and the second magnetic member 201 is not constrained, and the magnetic attraction force of mutual attraction can be restored. In this way, when the first body 10 and the second body 20 are fastened to a certain angle, the first magnetic member 101 and the second magnetic member 201 can be attracted, so that the first body 10 and the second body 20 can be relatively folded and maintained in the folded state.
In practical application, the control module is triggered by the position detection device 70 to drive the driving mechanism 60 to operate or stop operating, so that the position precision control of the magnetic tape separator can be improved, the precision requirement of the driving mechanism 60 can be reduced, and the structural complexity and the cost of the driving mechanism 60 can be reduced.
In some alternative embodiments of the present application, the sensing element 702 is an infrared detector, and the triggering element 701 is an infrared triggering element; alternatively, the sensing member 702 is a hall sensor, and the triggering member 701 is a magnetic member.
Specifically, under the condition that the sensing member 702 is the infrared detector and the triggering member 701 is the infrared triggering member, the infrared detector may be provided with an infrared emitting portion and an infrared receiving portion, and the infrared triggering lever member may be a metal plate capable of blocking an infrared signal. And under the condition that the infrared trigger piece is not rotated to the target position, an infrared receiving part on the infrared detector can receive a signal returned after an infrared signal sent by the infrared transmitting part is reflected, and at the moment, the infrared detector is not triggered. Under the condition that the infrared trigger piece rotates to the target position, the infrared trigger piece can block a signal reflected by the infrared signal, and at the moment, an infrared receiver on the infrared detector cannot receive the signal and is triggered to generate the induction signal.
Specifically, when the sensing element 702 is a hall sensor and the triggering element 701 is a magnetic element, the hall sensor may be triggered to generate the sensing signal when the magnetic element rotates to the target position along with the magnetic isolation strip.
For example, the trigger 701 may be connected to the magnetic shielding tape by an adhesive, a snap, or a fastener, and the like, and the connection manner of the trigger 701 on the magnetic shielding tape is not specifically limited in this embodiment of the application.
As shown in fig. 2, the driving mechanism 60 may specifically include a first driving member 601 and a transmission shaft 602; one end of the transmission shaft 602 is connected to the first driving member 601, and the other end is connected to one of the plurality of fixed shafts 503.
Specifically, because the magnetic isolation tape is arranged around the second magnetic member 201, the first driving member 601 only needs to drive the magnetic isolation tape to rotate in one direction, so that the magnetic isolation portion 501 or the non-magnetic isolation portion 502 on the magnetic isolation tape can be arranged between the first magnetic member 101 and the second magnetic member 201, and the first driving member 601 only needs to adopt a common motor.
Referring to fig. 4, a schematic structural diagram of another electronic device according to an embodiment of the present application is shown, referring to fig. 5, a schematic structural diagram of a part of components of the electronic device shown in fig. 4 is shown, and referring to fig. 6, a detailed structural diagram of a position of the electronic device a shown in fig. 5 is shown.
As shown in fig. 4 and 5, the magnetism isolating member 50 may include a magnetism isolating plate; in the folded state, in response to the unfolding operation, the driving mechanism 60 may drive the magnetic shield to extend between the first magnetic member 101 and the second magnetic member 201.
Specifically, in the folded state, in response to the unfolding operation, the driving mechanism 60 may drive the magnetism isolating plate to move toward the gap between the first magnetic member 101 and the second magnetic member 201, so that the magnetism isolating plate may extend between the first magnetic member 101 and the second magnetic member 201, and the magnetic attraction connection between the first magnetic member 101 and the second magnetic member 201 is released. In the unfolded state, the driving mechanism 60 can drive the magnetic isolation plate to move away from the gap between the first magnetic member 101 and the second magnetic member 201, so that the magnetic isolation plate can be disengaged from the gap between the first magnetic member 101 and the second magnetic member 201, the magnetic attraction force between the first magnetic member 101 and the second magnetic member 201 is recovered, and the control logic is simple.
For example, the magnetic shield plate may be made of a silicon steel plate or other material capable of shielding a magnetic field, and the specific material of the magnetic shield plate may not be limited in the embodiment of the present application.
Optionally, the electronic device may further include a fixer 80 respectively disposed at two ends of the magnetic shield; a guide groove 801 is arranged in the fixer 80, and at least part of the magnetism isolating plate is arranged in the guide groove 801 in a penetrating way and can slide along the guide groove 801; the driving mechanism 60 is connected to at least one end of the magnetic isolation plate, and the driving mechanism 60 may be configured to drive the magnetic isolation plate to slide along the guide groove 801, so that the magnetic isolation plate extends between the first magnetic member 101 and the second magnetic member 201, or slides out from between the first magnetic member 101 and the second magnetic member 201.
In practical application, the magnetic shield plate can be reliably supported by respectively arranging the fixing devices 80 for fixing the magnetic shield plate at the two ends of the magnetic shield plate. The sliding accuracy of the magnetic shield can be improved by providing the guide groove 801 in the holder 80 and driving the magnetic shield to slide only along the guide groove 801.
Alternatively, the driving mechanism 60 may specifically include: a second driving member 603 and a screw driving shaft 604, the second driving member 603 being connected to the screw driving shaft 604; the end of the magnetism isolating plate is provided with a thread tooth which is meshed with the spiral driving shaft 604; the second driving member 603 can drive the screw driving shaft 604 to rotate, so that the magnetic-isolating plate is driven to slide along the guiding groove 801 by the rotation of the screw driving shaft 604.
Specifically, since the second driving member 603 needs to drive the magnetic shielding plate to move closer to or away from the gap between the first magnetic member 101 and the second magnetic member 201, the second driving member 603 needs to adopt a stepping motor capable of realizing forward and reverse rotation.
For example, in a case where the magnetic shielding plate needs to be inserted into the gap between the first magnetic member 101 and the second magnetic member 201, the second driving member 603 may drive the screw driving shaft 604 to rotate forward, so that the magnetic shielding plate is driven to slide along the guide groove 801 to the gap between the first magnetic member 101 and the second magnetic member 201 by the forward rotation of the screw driving shaft 604. In the case that the magnetic shielding plate needs to be removed from the gap between the first magnetic member 101 and the second magnetic member 201, the second driving member 603 may drive the screw driving shaft 604 to rotate reversely, so that the magnetic shielding plate is driven to slide out of the gap between the first magnetic member 101 and the second magnetic member 201 along the guide groove 801 by the reverse rotation of the screw driving shaft 604.

in the embodiment of the application, a magnetism isolating piece and a driving mechanism may be disposed in the first body or the second body of the electronic device, and the driving mechanism may control the movement of the magnetism isolating piece. When the electronic device is in the folded state, in response to an unfolding operation, the driving mechanism can drive the magnetism isolating piece to move to a position between the first magnetic piece and the second magnetic piece, and magnetic adsorption between the first magnetic piece and the second magnetic piece is released. Thus, the first magnetic member and the second magnetic member no longer have a magnetic attraction force capable of holding the folded state. The user can open the first body and the second body with small effort, and the use experience of the user on the electronic equipment is greatly improved.
