The electronic device and the control method of the electronic device provided by the embodiment of the present application are respectively described in detail below with reference to fig. 1 to 6 through specific embodiments and application scenarios thereof.
According to an embodiment of the present application, an electronic device is provided, and referring to fig. 1 to 4, the electronic device includes a first circuit board 1, the first circuit board 1 includes a conductive layer 101 and a protective layer 102 disposed on the conductive layer 101; a first magnetic member 103 is disposed in the protective layer 102, or a first magnetic member 103 is disposed on one side of the protective layer 102. Referring to fig. 5, the electronic device further includes a second magnetic member 3, the second magnetic member 3 is disposed opposite to the first magnetic member 103, and the first magnetic member 103 and the second magnetic member 3 are mutually exclusive when the circuit board 1 approaches the second magnetic member 3.
In addition, in some examples of the present application, the electronic device further includes a display screen and a device housing, the display screen covers the device housing, the display screen and the device housing enclose to form an accommodating cavity, and the first circuit board 1 and the second magnetic member 3 are both disposed in the accommodating cavity.
Wherein, the display screen is a folding screen, for example. At this time, referring to fig. 5, the electronic apparatus is, for example, a folder type electronic apparatus, which may include a first body 4 and a second body 5 rotatably connected.
The folding screen can freely switch between the folded state and the unfolded state along with the electronic equipment, the size of the display screen can be adjusted according to the requirement by a user, and two ends of the first circuit board 1 are respectively connected with the first body 4 and the second body 5. When the folding screen is switched between the folded state and the unfolded state, the first circuit board 1 can be bent or unfolded along with the folding screen. In this process, when the first circuit board 1 approaches the second magnetic member 3, a repulsive magnetic force is generated between the first magnetic member 103 and the second magnetic member 3, so that the first circuit board 1 does not generate a friction loss due to frequent contact with related components (disposed in the direction of the second magnetic member, or directly carrying the second magnetic member).
It is to be understood that the electronic device provided in the embodiments of the present application is not limited to the folding screen electronic device, and may also be a general electronic device, and the embodiments of the present application are not limited specifically herein.
In the embodiment of the present application, the first circuit board 1 itself is a multilayer composite structure.
For example, the first circuit board 1 includes a conductive layer 101, a protective layer 102 is disposed on the conductive layer 101, and a magnetic conductive material is added into the protective layer 102, so that the first magnetic member 103 is formed in the protective layer 102 or on one side of the protective layer 102, as shown in fig. 2 and 3.
It should be noted that the protection layers 102 are disposed on two surfaces of the conductive layer 101, for example, to completely wrap the conductive layer 101, so as to completely protect the conductive layer 101, see fig. 1.
For another example, the protective layer 102 is provided only on one surface of the conductive layer 101, and when the protective layer 102 is provided in the electronic device, the protective layer 102 needs to be provided toward the second magnetic member 3 so that the first magnetic member 103 in the protective layer 102 can be opposed to and close to the second magnetic member 3.
In the embodiment of the present application, the second magnetic member 3 is disposed inside the electronic device.
For example, the second magnetic member 3 may be provided on a component that is easily brought into contact with the first circuit board 1, and the second magnetic member 3 is designed to be disposed opposite to the first magnetic member 103. The second magnetic member 3 mainly functions to generate a repulsive magnetic force with the same polarity as the first magnetic member 103, so that the repulsive magnetic force can be used as a driving force to drive the first circuit board 1 to avoid contacting with related components in the electronic device, and thus the first circuit board 1 does not have a contact friction loss, so that the service life of the circuit board can be prolonged, and the defects in the prior art can be overcome.
In the embodiment of the present application, by disposing the first magnetic member 103 in the protective layer 102 of the first circuit board 1, or by disposing the second magnetic member 3 opposite to the first magnetic member 103 on one side of the protective layer 102, a mutual-exclusion magnetic force generated between the second magnetic member 3 and the first magnetic member 103 can be used to avoid a situation that the first circuit board 1 is in contact with related components to cause friction loss, so as to effectively increase the service life of the first circuit board 1. Thereby contributing to extending the useful life of the electronic device.
That is, in the embodiment of the present application, the protective layer 102 with the magnetic conductive material may be used instead of the ordinary protective layer, and the magnetic force generated after the magnetic conductive material is energized is used to reduce the contact friction loss of the circuit board.
In some examples of the present application, when the first magnetic member 103 moves toward the direction close to the second magnetic member 3, the first magnetic member 103 and the second magnetic member 3 mutually repel each other.
It can be understood that, when the first circuit board 1 moves towards the direction of the second magnetic member 3, the first magnetic member 103 moves towards the second magnetic member 3 together, in this case, a repulsive magnetic force is generated between the first magnetic member 103 and the second magnetic member 3, and at this time, the relevant components arranged in the direction of the second magnetic member 3 can keep a certain distance from the first circuit board 1 to avoid direct contact, so that a friction loss condition caused by contact can be avoided.
In some examples of the present application, referring to fig. 2 and 3, the first circuit board 1 is a flexible circuit board (FPC), and the first circuit board 1 may be bent;
the first circuit board 1 is provided with an electrical terminal 105, the first magnetic member 103 is electrically connected with the electrical terminal 105 to generate a magnetic force mutually exclusive with the second magnetic member 3, and the first magnetic member 103 and the second magnetic member 3 mutually exclusive enable the first circuit board 1 to be far away from the second magnetic member 3.
In the embodiment of the present application, the material of the first magnetic member 103 is, for example, a material which does not have a magnetic force, and the magnetic force needs to be generated after the first magnetic member is energized. That is, the first magnetic member 103 is electrically connected to the electrical terminal 105, and the first magnetic member 103 generates a magnetic force repelling the second magnetic member 3 after being energized.
The reason for this design in the embodiments of the present application is that: if a magnetic material is directly added to the protection layer 102, the magnetic material may cause certain interference to the traces of the first circuit board 1. Therefore, the embodiment of the present application is designed according to the principle of "electromagnetic induction".
In some examples of the present application, referring to fig. 2 and 3, the electrical terminals 105 are disposed on both sides of the first circuit board 1; the first circuit board 1 is provided with a bending area 106, and the bending area 106 is positioned between the electric terminals 105 at two sides of the first circuit board 1;
the first magnetic member 103 includes a first portion 1031 located in the bending region 106 and a second portion 1032 located between the bending region 106 and the electrical terminal 105, and the width of the first portion 1031 is greater than that of the second portion 1032.
Wherein the first magnetic member 103 is a ferrite material disposed in the protective layer 102 or on one side of the protective layer 102, and the width of the first magnetic member 103 is gradually narrowed toward the electric terminal 105.
In the present embodiment, the width direction of the first magnetic member 103 is the same as the width direction of the first circuit board 1, and the electrical terminals 105 are disposed on both sides of the first magnetic member 103 along the length direction of the first circuit board 1. It can be understood that the width direction of the first magnetic member 103 is perpendicular to the direction of current flow within the first magnetic member 103.
For example, referring to fig. 2 and 3, the electrical terminals 105 are provided in two, the two electrical terminals 105 are respectively provided at both sides of the first circuit board 1, both ends of the first magnetic member 103 are electrically connected to the two electrical terminals 105 one to one, and one of the electrical terminals 105 may also be grounded.
In the embodiment of the present application, the width of the first magnetic member 103 is varied, specifically, gradually narrowed toward the electrical terminal 105. This facilitates electrical connection with the electrical terminals 105. The two side parts of the first magnetic part 103 are designed to be gradually narrowed, and the connection part with the electric connection terminal 105 is concentrated at one point, so that the power supply of the power supply part is facilitated, the number (pin) of the terminals occupied by the first magnetic part 103 and the number of the electric wires electrically connected with the first magnetic part 103 are saved, and the effects of simplifying the circuit structure and saving the cost can be achieved to a certain extent.
In the embodiment of the present application, the first circuit board 1 has a bending region, can be bent, and is suitable for a folding screen electronic device.
The first magnetic member 103 comprises the first portion 1031 and the second portion 1032, the first portion 1031 is located in the bending region 106, and the second portion 1032 is located between the bending region 106 and the electrical terminal 105
In the folding electronic apparatus, the first circuit board 1 is located between the first body 4 and the second body 5 of the folding electronic apparatus. When the foldable electronic device is opened, the bending region 106 of the first circuit board 1 is located in the middle region of the first circuit board 1. That is, the first portion 1031 is located in a middle region of the first circuit board 1. The second portion 1032 is located on both sides of the first portion 1031 in this embodiment, it being understood that the second portion 1032 may be located on only one side of the first portion 1031 in some embodiments.
When the foldable electronic device is opened, the bending region 106 of the first circuit board 1 is pressed severely and generates a certain displacement, and based on this, the width dimension of the first portion 1031 of the first magnetic member 103 located in the bending region 106 is designed to be larger than the width dimension of the second portion 1032 located between the bending region 106 and the electrical terminals 105. In this way, after the first magnetic member 103 is energized to generate a magnetic force, for example, a larger repulsive force is generated in the bending region 106 of the first circuit board 1, so as to prevent the bending region 106 of the first circuit board 1 from contacting an adjacent device during the movement process, thereby better protecting the circuit board.
In a specific example of the present application, referring to fig. 2 and 3, the top view of the first magnetic member 103 is a diamond shape. The diamond-shaped design conforms to the above-mentioned structure design in which the first portion 1031 is wider, and the second portions 1032 on both sides are gradually narrower. Meanwhile, the diamond design can concentrate the connection position of the first magnetic member 103 (such as ferrite) and the electrical terminal 105 at one point, which is beneficial for the power supply part to supply power to the connection position. Particularly, power supply for the first magnetic member 103 (for example, ferrite) can be ensured through one wire, so that the number of the electrical terminals 105 occupied by the first magnetic member 103 and the branch of the power wire electrically connected to the first magnetic member 103 can be reduced, and the manufacturing cost of the circuit board can be reduced.
In some examples of the present application, the first magnetic member 103 is a ferrite magnetic sheet electrically connected to an external circuit, and the magnetic sheet is energized to generate a magnetic force mutually repelling from the second magnetic member 3 under the action of an external current.
Ferrite materials do not have magnetic properties themselves, and need to be energized to generate magnetic force. The design requirement of the scheme of the application is met.
The first magnetic member 103 may also be made of other magnetic materials known to those skilled in the art, and is not limited to the ferrite material, and the application is not limited thereto.
In some examples of the present application, the first magnetic element 103 may also be a coil, which is electrically connected to an external circuit, and is energized to generate a magnetic force mutually repelling the second magnetic element 3 under the action of an external current.
It should be noted that the structural form of the first magnetic member 103 includes, but is not limited to, the above-mentioned magnetic sheet or coil, and a person skilled in the art can design the first magnetic member as needed, and the embodiment of the present application is not limited in particular.
In some examples of the present application, referring to fig. 5, the electronic device includes a first body 4 and a second body 5 rotatably connected, and a second circuit board 2, referring to fig. 4; the second magnetic member 3 is arranged in the protective layer of the second circuit board 2, or the second magnetic member 3 is arranged on one side of the protective layer of the second circuit board 2;
the two ends of the first circuit board 1 and/or the second circuit board 2 are respectively connected with the first body 4 and the second body 5, the first magnetic part 103 and the second magnetic part 3 comprise ferrite materials, and one side of the first circuit board 1, which is provided with the first magnetic part 103, is opposite to and close to one side of the second circuit board 2, which is provided with the second magnetic part 3.
The electronic device is, for example, a foldable electronic device, and includes a first body 4 and a second body 5, where the first body 4 and the second body 5 are rotatably connected, and the foldable and unfoldable functions of the electronic device can be realized.
It is understood that, in the electronic device, besides the first circuit board 1, the second circuit board 2 is also used, the second magnetic member 3 may be disposed on the second circuit board 2, and the first magnetic member 103 and the second magnetic member 3 are opposite and close to each other. In the process that the first circuit board 1 is close to the second circuit board 2, the first circuit board 1 and the second circuit board 2 are mutually exclusive, so that the first circuit board 1 and the second circuit board 2 are not in contact with each other, and friction loss between the two circuit boards can be avoided.
In the embodiment of the present application, the second circuit board 2 is, for example, a multilayer composite structure, which may be the same as the first circuit board 1.
Specifically, the second circuit board 2 includes a conductive layer and a protective layer disposed on the conductive layer, and on this basis, the second magnetic member 3 is disposed in the protective layer, or the second magnetic member is disposed on one side of the protective layer.
In some examples of the present application, the first circuit board 1 and the second circuit board 2 are disposed in parallel.
Two ends of the first circuit board 1 and the second circuit board 2 are respectively connected with the first body 4 and the second body 5 through electric terminals 105, and a bending area 106 of the first circuit board 1 is opposite to a bending area of the second circuit board 2; the first magnetic member 103 includes a first portion 1031 located in the bending region 106 of the first circuit board 1 and a second portion 1032 located between the bending region 106 of the first circuit board 1 and the electrical terminal 105, and the width of the first portion 1031 is greater than the width of the second portion 1032. The orthographic projection of the second magnetic member 3 on the first circuit board 1 covers the first magnetic member 103 to ensure that the repulsion between the bending region 106 of the first circuit board 1 and the second circuit board 2 is maximum.
In the embodiment of the present application, by controlling the mutually exclusive magnetic force generated between the first magnetic member 103 and the second magnetic member 3, the two circuit boards can be prevented from contacting each other, and further, the two circuit boards can be prevented from being worn due to friction. The first circuit board 1 and the second circuit board 2 are completely not in contact with each other, and a certain gap is always kept between the first circuit board 1 and the second circuit board 2 through the mutual repulsion between the first magnetic part 1 and the second magnetic part 3. This prevents the occurrence of a loss due to contact, and thus the service life of the circuit board can be extended.
It should be noted that, when the first circuit board 1 and the second circuit board 2 are disposed in the electronic device, the relative positions of the first circuit board 1 and the second circuit board 2 include, but are not limited to, being disposed in parallel with each other, and a person skilled in the art can flexibly adjust the positional relationship between the two according to needs, and the embodiment of the present application is not limited in particular herein.

Wherein, the first magnetic part 103 and the second magnetic part 3 have the same shape, so that the orthographic projections of the two parts can be completely overlapped. Thus, in the process that the first circuit board 1 is close to the second circuit board 2, the first magnetic part 103 and the second magnetic part 3 can generate an evenly distributed mutual repulsion force, so that a reasonable interval is formed and maintained between the two circuit boards, and the circuit boards can be prevented from being turned and deflected while the two circuit boards are prevented from being in contact with each other and worn.
In the embodiment of the present application, referring to fig. 3, the first circuit board 1 further includes, for example, two power supply portions 107. Two power supply portions 107 are provided on, for example, both sides of the first circuit board 1, and are electrically connected to the conductive layer 101. The electrical connection terminal 105 may be electrically connected to the power supply portion 107 or may be drawn out from the power supply portion 107.
