[0026] The following is a further description of the embodiments of the present application in conjunction with the accompanying drawings. The same or similar reference numerals in the accompanying drawings represent the same or similar elements or elements with the same or similar functions from beginning to end. In addition, the embodiments of the present application described below in conjunction with the accompanying drawings are exemplary and are only used to explain the embodiments of the present application, and cannot be understood as limiting the present application.

[0027] A foldable electronic device generally includes a first sub-section and a second sub-section, and the first sub-section and the second sub-section are bent relative to each other so as to be folded into a device form with a smaller area. Currently, in order to solve the tension problem after the first sub-section and the second sub-section are folded, the electronic device is provided with magnets at positions corresponding to the first sub-section and the second sub-section, and the folded form of the electronic device is maintained by adsorption of the magnets. However, when the electronic device is in the unfolded state, the magnets are prone to adsorb some metal foreign matter. If the user is not careful, the adsorbed metal foreign matter is prone to crush and damage the screen when the electronic device is folded. In order to solve this problem, an embodiment of the present application provides an electronic device 100( Figure 1 shown).

[0028] See also Figure 1 and Figure 2 The electronic device 100 of the embodiment of the present application includes a body 10, a magnetic component 20 and an adjustment component 30. The body 10 includes a first sub-section 11 and a second sub-section 13. The first sub-section 11 and the second sub-section 13 can rotate relative to each other so that the electronic device 100 can be in a folded state or an unfolded state. The body 10 includes a first surface 15 and a second surface 17 opposite to each other. When the electronic device 100 is in an unfolded state, the first surface 15 and the second surface 17 are respectively located on opposite sides of the body 10. When the electronic device 100 is in a folded state, the first surface 111 of the first sub-section 11 faces the first surface 131 of the second sub-section 13, and the second surface 113 of the first sub-section 11 and the second surface 133 of the second sub-section 13 are respectively located on opposite sides of the body 10. The magnetic component 20 includes a first magnetic member 21 and a second magnetic member 23. The first magnetic member 21 is arranged on the first sub-section 11, and the second magnetic member 23 is arranged on the second sub-section 13. The adjustment component 30 includes a first adjustment member 31 disposed on the first sub-portion 11, the first adjustment member 31 corresponds to the first magnetic member 21, and the first adjustment member 31 is used to adjust the distance between the first magnetic member 21 and the first surface 15. Wherein: when the electronic device 100 is in the unfolded state, the first magnetic member 21 and the second magnetic member 23 do not generate attraction to the object on the first surface 15; when the electronic device 100 is in the folded state, the first adjustment member 31 adjusts the distance between the first magnetic member 21 and the first surface 15, so that the first magnetic member 21 and the second magnetic member 23 are attracted.

[0029] Specifically, the electronic device 100 of the present application is an electronic device 100 with a foldable function, and the foldable electronic device 100 may be, but is not limited to, a foldable mobile phone, a tablet computer, an e-reader, a wearable device, etc. The foldable electronic device 100 may be a flexible electronic device 100, or may be a non-flexible electronic device 100 that realizes the folding function through a rotating shaft. The electronic device 100 in the present application is described by taking a foldable mobile phone as an example.

[0030] The body 10 refers to the structure of the electronic device 100 for loading other components. In some embodiments, the body 10 may include a housing. Other components include, but are not limited to, a camera module and a fingerprint module. According to the folding and unfolding state of the electronic device 100, the body 10 can be divided into a first sub-unit 11 and a second sub-unit 13. The sizes of the first sub-unit 11 and the second sub-unit 13 can be the same, so that after the first sub-unit 11 and the second sub-unit 13 are relatively folded, the electronic device 100 is as small as possible. When the electronic device 100 has only one display screen and the display screen is a conventional main screen, the first surface 15 of the body 10 is the side close to the display area, and the second surface 17 of the body 10 is the side away from the display area. Similarly, the first surface 111 of the first sub-unit 11 is the side close to the display area, and the second surface 113 of the first sub-unit 11 is the side away from the display area. The first surface 131 of the second sub-unit 13 is the side close to the display area, and the second surface 133 of the second sub-unit 13 is the side away from the display area. In the present application, the first surface 111 of the first sub-section 11, the first surface 131 of the second sub-section 13 and the first surface 15 of the main body 10 are the same plane, and the second surface 113 of the first sub-section 11, the second surface 133 of the second sub-section 13 and the second surface 17 of the main body 10 are also the same plane.

[0031] The first surface 111 of the first sub-unit 11 and the first surface 131 of the second sub-unit 13 in the folded state of the present application are opposite, and the angle between the two is less than the preset threshold value α. The unfolded state of the present application is a state in which the angle between the first surface 111 of the first sub-unit 11 and the first surface 131 of the second sub-unit 13 is greater than or equal to the preset threshold value α and less than or equal to 180°. Among them, the preset threshold value α is a smaller angle range, and its value can be either an empirical value obtained before the electronic device 100 leaves the factory, or a set value input when the electronic device 100 is manually used after the electronic device 100 leaves the factory, or an empirical value obtained by the processor 80 processing historical data after the electronic device 100 leaves the factory, which is not limited here. In the present application, the value range of the preset threshold value α can be [5°, 30°]. When the electronic device 100 is in the folded state, the electronic device 100 is smaller in size and lighter to carry. When the electronic device 100 is in the unfolded state, the electronic device 100 can use various software functions, especially to meet the user's large screen usage experience.

[0032] The magnetic component 20 is a structure that can attract or repel other components through its own magnetic field. For example, the magnetic component 20 can magnetically attract magnetic objects, and the magnetic component 20 can also attract or repel other magnetic components. In one embodiment, the first magnetic component 21 is a magnet. In another embodiment, the first magnetic component 21 is another magnetic object. In one embodiment, the second magnetic component 23 is a magnet. In another embodiment, the second magnetic component 23 is another magnetic object. In one example, the first magnetic component 21 is a magnet, and the second magnetic component 23 is a magnet. In another example, the first magnetic component 21 is a magnet, and the second magnetic component 23 is a magnet. In another example, the first magnetic component 21 is a magnet, and the second magnetic component 23 is another magnetic object. In another example, the first magnetic component 21 is another magnetic object, and the second magnetic component 23 is another magnetic object, wherein the first magnetic component 21 and the second magnetic component 23 can be the same object or different objects.

[0033] The shape of the first magnetic member 21 may be, but is not limited to, circular, elliptical, rectangular or other polygonal shapes. The size of the first magnetic member 21 is at least smaller than the size of the first sub-section 11. The number of the first magnetic member 21 may be one, two or more. In the case where there is one first magnetic member 21, the first magnetic member 21 may be arranged at any position of the first sub-section 11. Preferably, the first magnetic member 21 is arranged at the center position of the side of the first magnetic member 21 away from the second magnetic member 23, so that when the electronic device 100 is in a folded state, the first sub-section 11 and the second sub-section 13 are subjected to more uniform force and more stable suction. In the case where there are two first magnetic members 21, the two first magnetic members 21 may be arranged at any position of the first sub-section 11. Preferably, the two first magnetic members 21 are respectively arranged at two corners of the side of the first magnetic member 21 away from the second magnetic member 23, so that when the electronic device 100 is in a folded state, the first sub-section 11 and the second sub-section 13 are subjected to more uniform force and more stable suction. In the case where there are multiple first magnetic members 21, the multiple first magnetic members 21 can be evenly or unevenly arranged at any position of the first sub-section 11. Preferably, the multiple first magnetic members 21 are evenly arranged at a position on the side of the first magnetic member 21 away from the second magnetic member 23, so that when the electronic device 100 is in a folded state, the first sub-section 11 and the second sub-section 13 are subjected to more even force and the attraction is more stable.

[0034] The shape of the second magnetic member 23 may be, but is not limited to, circular, elliptical, rectangular or other polygonal shapes. The size of the second magnetic member 23 is at least smaller than the size of the second sub-section 13. The number of the second magnetic member 23 may be one, two or more. In the case where the second magnetic member 23 is one, the second magnetic member 23 may be arranged at any position of the second sub-section 13. Preferably, the second magnetic member 23 is arranged at the center position of the side of the second magnetic member 23 away from the first magnetic member 21, so that when the electronic device 100 is in a folded state, the first sub-section 11 and the second sub-section 13 are more evenly stressed and more firmly attracted. In the case where there are two second magnetic members 23, the two second magnetic members 23 may be arranged at any position of the second sub-section 13. Preferably, the two second magnetic members 23 are respectively arranged at two corners of the side of the second magnetic member 23 away from the first magnetic member 21, so that when the electronic device 100 is in a folded state, the first sub-section 11 and the second sub-section 13 are more evenly stressed and more firmly attracted. In the case where there are multiple second magnetic members 23, the multiple second magnetic members 23 can be evenly or unevenly arranged at any position of the second sub-section 13. Preferably, the multiple second magnetic members 23 are evenly arranged at a position on the side of the second magnetic member 23 away from the first magnetic member 21, so that when the electronic device 100 is in a folded state, the first sub-section 11 and the second sub-section 13 are more evenly stressed and more firmly attracted. The shapes of the second magnetic member 23 and the first magnetic member 21 can be the same or different, the numbers of the second magnetic member 23 and the first magnetic member 21 can be the same or different, and the sizes of the second magnetic member 23 and the first magnetic member 21 can be the same or different. Preferably, the second magnetic member 23 and the first magnetic member 21 are the same in shape, number and size, and the setting position of the second magnetic member 23 corresponds to the setting position of the first magnetic member 21.

[0035] In one embodiment, the magnetic pole of the first magnetic member 21 on the side close to the first surface 15 is an N pole, and the magnetic pole of the first magnetic member 21 on the side away from the first surface 15 is an S pole. The magnetic pole of the second magnetic member 23 on the side close to the first surface 15 is an S pole, and the magnetic pole of the second magnetic member 23 on the side away from the first surface 15 is an N pole. In another embodiment, the magnetic pole of the first magnetic member 21 on the side close to the first surface 15 is an S pole, and the magnetic pole of the first magnetic member 21 on the side away from the first surface 15 is an N pole. The magnetic pole of the second magnetic member 23 on the side close to the first surface 15 is an N pole, and the magnetic pole of the second magnetic member 23 on the side away from the first surface 15 is an S pole. In this application, the magnetic pole of the first magnetic member 21 on the side close to the first surface 15 is an N pole, the magnetic pole of the first magnetic member 21 on the side away from the first surface 15 is an S pole, the magnetic pole of the second magnetic member 23 on the side close to the first surface 15 is an S pole, and the magnetic pole of the second magnetic member 23 on the side away from the first surface 15 is an N pole.

[0036] Please continue reading Figure 1 and Figure 2 In some embodiments, when the electronic device 100 is in a folded state, the first magnetic member 21 and the second magnetic member 23 at least partially overlap in the thickness direction. The first magnetic member 21 and the second magnetic member 23 may partially overlap or completely overlap in the thickness direction, as long as the N pole of the first magnetic member 21 and the S pole of the second magnetic member 23 can attract each other with opposite poles.

[0037] Please continue reading Figure 1 and Figure 2 In other embodiments, when the electronic device 100 is in the unfolded state, the first magnetic member 21 and the second magnetic member 23 are symmetrical about the folding axis of the body 10. At this time, when the electronic device 100 is in the folded state, the first magnetic member 21 and the second magnetic member 23 can completely overlap. The N pole of the first magnetic member 21 and the S pole of the second magnetic member 23 attract each other, so that the first sub-portion 11 and the second sub-portion 13 are attracted.

[0038] The adjustment component 30 is a structure for adjusting the position of other components. The adjustment component 30 of the present application is used to adjust the position of the magnetic component 20. The first adjustment member 31 is provided on a side of the first magnetic member 21 away from the first surface 15. The first adjustment member 31 can act on the first magnetic member 21 in a contactable or non-contactable manner to adjust the distance of the first magnetic member 21 relative to the first surface 15.

[0039] The external object is an object that can be attracted by the magnetic member, and the external object includes but is not limited to an object containing metals such as iron, cobalt and nickel.

[0040] In the electronic device 100 of the present application, when the electronic device 100 is in a folded state, the first magnetic member 21 is adjusted by the first adjusting member 31 so that the first magnetic member 21 is close to the first surface 15, and the first magnetic member 21 and the second magnetic member 23 attract each other, so that the first sub-section 11 and the second sub-section 13 are attracted. When the electronic device 100 is in an unfolded state, the first magnetic member 21 is adjusted by the first adjusting member 31 so that the first magnetic member 21 is away from the first surface 15, and the magnetic force of the first magnetic member 21 is not enough to absorb foreign objects. The distance from the second magnetic member 23 to the first surface 15 also makes the magnetic force of the second magnetic member 23 not enough to absorb foreign objects. The magnetic component 20 is not enough to absorb foreign objects when the electronic device 100 is in an unfolded state, so that the electronic device 100 will not be crushed and damaged by the adsorbed foreign objects on the surface of the electronic device 100 when it is in a folded state.

[0041] The electronic device 100 is further described below with reference to the accompanying drawings.

[0042] See also Figure 1 and Figure 2 In some embodiments, when the electronic device 100 is in the unfolded state, the first distance X1 between the first magnetic member 21 and the first surface 15 is greater than the first preset distance X0, and the second distance Y1 between the second magnetic member 23 and the first surface 15 is greater than the second preset distance Y0. The first preset distance X0 is a critical distance at which the first magnetic member 21 can adsorb external objects to the electronic device 100, and the second preset distance Y0 is a critical distance at which the second magnetic member 23 can adsorb external objects to the electronic device 100. When the electronic device 100 is in the folded state, the first magnetic member 21 is separated from the first surface 15 by a third distance X2, and the third distance X2 is less than the first distance X1. The first magnetic member 21 and the second magnetic member 23 cooperate to generate a first attraction, and the first attraction is used to make the first sub-portion 11 and the second sub-portion 13 attract each other.

[0043] When the electronic device 100 is in a folded state, the first magnetic member 21 and the second magnetic member 23 attract each other so that the first sub-section 11 and the second sub-section 13 are attracted. When the electronic device 100 is in an unfolded state, the first adjustment member 31 adjusts the first magnetic member 21 so that the distance between the first magnetic member 21 and the first surface 15 is X1. When the distance between the first magnetic member 21 and the first surface 15 is X1, the magnetic force of the first magnetic member 21 is not enough to absorb foreign objects. When the distance between the second magnetic member 23 and the first surface 15 is Y1, the magnetic force of the second magnetic member 23 is not enough to absorb foreign objects. The magnetic component 20 is not enough to absorb foreign objects when the electronic device 100 is in an unfolded state, so that the electronic device 100 will not be crushed and damaged by the adsorbed foreign objects on the surface of the electronic device 100 when it is in a folded state.

[0044] See also Figure 2 In some embodiments, the electronic device 100 further includes a first bracket 40, the first bracket 40 is disposed in the body 10, the first magnetic member 21 is movably mounted on the first bracket 40, and the first adjusting member 31 is fixedly connected to the first bracket 40. Specifically, the first bracket 40 is a structure for mounting and connecting other components. The first bracket 40 of the present application is used to mount and support the first magnetic member 21 and connect the first adjusting member 31. The first bracket 40 is disposed in the first sub-section 11 and corresponds to the positions of the first magnetic member 21 and the first adjusting member 31.

[0045] See also Figure 2In some embodiments, the first adjusting member 31 is a magnetic member, and the first adjusting member 31 cooperates with the first magnetic member 21 to generate a second attractive force, the first attractive force is greater than the second attractive force, and when the electronic device 100 is in the unfolded state, the second attractive force is used to make the first distance X1 between the first magnetic member 21 and the first surface 15 greater than the first preset distance X0, and when the electronic device 100 is in the folded state, the third distance X2 is less than the first distance X1.

[0046] Specifically, the magnetic part is a structure that attracts other components through its own magnetic field. The magnetic part can be a magnet or other magnetic objects. The magnetic part can be installed on the same side of the first bracket 40 as the first magnetic part 21, or on the opposite side of the first bracket 40 and the first magnetic part 21, as long as the magnetic part can generate a second attractive force with the first magnetic part 21. The magnetic part can be installed on the first bracket 40 by methods such as dispensing or welding.

[0047] In one embodiment, the first adjusting member 31 and the first magnetic member 21 are different magnets. In another embodiment, the first adjusting member 31 and the first magnetic member 21 are the same magnet. The side of the first adjusting member 31 close to the first magnetic member 21 is the N pole, and the side of the first adjusting member 31 away from the first magnetic member 21 is the S pole, so that when the electronic device 100 is in the unfolded state, the S pole of the first magnetic member 21 and the N pole of the first adjusting member 31 are attracted to each other, so that the distance from the first magnetic member 21 to the first surface 15 is X1. At this time, the magnetic force of the first magnetic member 21 is not enough to attract external objects. According to the formula F=K / R 2 It can be known that the magnetic attraction force F is proportional to the magnetic field strength K, and the magnetic attraction force F is inversely proportional to the distance R. In one embodiment, the size of the first magnetic member 21 and the second magnetic member 23 is larger than the size of the first adjusting member 31, so that when the electronic device 100 is in a folded state, the first attraction is greater than the second attraction. In another embodiment, when the electronic device 100 is in a folded state, the distance between the first magnetic member 21 and the second magnetic member 23 is smaller than the distance between the first magnetic member 21 and the first adjusting member 31, so that the first attraction is greater than the second attraction. The size of the first magnetic member 21 and the second magnetic member 23 in the embodiment of the present application is larger than the size of the first adjusting member 31, so that the first attraction is greater than the second attraction.

[0048] See also Figure 3In some other embodiments, the first adjusting member 31 is an electromagnet. When the electronic device 100 is in the unfolded state, the first adjusting member 31 is energized to cooperate with the first magnetic member 21 to generate a second attractive force, and the second attractive force is used to make the first distance X1 between the first magnetic member 21 and the first surface 15 greater than the first preset distance X0; when the electronic device 100 is in the folded state, the first adjusting member 31 is de-energized, and the first attractive force pulls the first magnetic member 21 toward the second magnetic member 23.

[0049] Specifically, the electromagnet is a structure that generates magnetic force when powered on to attract or repel other elements. The electromagnet of the present application is used to generate magnetic force when powered on to attract or repel the first magnetic member 21. The electromagnet can be installed on the same side of the first bracket 40 as the first magnetic member 21, or the electromagnet can be installed on the opposite side of the first bracket 40 from the first magnetic member 21, as long as the electromagnet can generate the second attractive force with the first magnetic member 21.

[0050] When the power is on, according to the direction of the current, it can be known from the right-hand screw rule that the side of the first adjusting member 31 close to the first magnetic member 21 is the N pole, and the side of the first adjusting member 31 away from the first magnetic member 21 is the S pole, so that when the electronic device 100 is in the unfolded state, the S pole of the first magnetic member 21 and the N pole of the first adjusting member 31 attract each other, so that the distance from the first magnetic member 21 to the first surface 15 is X1, and at this time, the magnetic force of the first magnetic member 21 is not enough to attract external objects. When the power is off, the first adjusting member 31 has no magnetic force, and there is no attraction between the first adjusting member 31 and the first magnetic member 21, so that when the electronic device 100 is in the folded state, the first magnetic member 21 and the second magnetic member 23 attract the first sub-section 11 and the second sub-section 13 due to the first attraction.

[0051] See also Figure 4 In some other embodiments, the first adjusting member 31 is an electromagnet. When the electronic device 100 is in the unfolded state, the first adjusting member 31 is powered off, and the first distance X1 between the first magnetic member 21 and the first surface 15 is greater than the first preset distance X0. When the electronic device 100 is in the folded state, the first adjusting member 31 is powered on to cooperate with the first magnetic member 21 to generate a repulsive force, and the repulsive force causes the first magnetic member 21 to move toward the second magnetic member 23, so that the first magnetic member 21 and the second magnetic member 23 cooperate to generate a first attractive force.

[0052] Specifically, when the power is off, the first adjusting member 31 has no magnetic force, and there is no attraction between the first adjusting member 31 and the first magnetic member 21. When the electronic device 100 is in the unfolded state, the first magnetic member 21 is placed on the first bracket 40, and the distance from the first magnetic member 21 to the first surface 15 is X1. At this time, the magnetic force of the first magnetic member 21 is not enough to attract external objects. When the power is on, according to the direction of the current, it can be known from the right-hand screw rule that the side of the first adjusting member 31 close to the first magnetic member 21 is the S pole, and the side of the first adjusting member 31 away from the first magnetic member 21 is the N pole, so that when the electronic device 100 is in the folded state, the S pole of the first magnetic member 21 and the S pole of the first adjusting member 31 repel each other, and the repulsive force causes the first magnetic member 21 to move toward the first surface 15, and the first magnetic member 21 and the second magnetic member 23 attract the first sub-portion 11 and the second sub-portion 13 due to the first attraction.

[0053] See also Figure 5 In some further embodiments, the first adjusting member 31 is an electromagnet. When the electronic device 100 is in the unfolded state, the first adjusting member 31 passes current in a first direction to cooperate with the first magnetic member 21 to generate a second attractive force, and the second attractive force is used to make the first distance X1 between the first magnetic member 21 and the first surface 15 greater than the first preset distance X0; when the electronic device 100 is in the folded state, the first adjusting member 31 passes current in a second direction to cooperate with the first magnetic member 21 to generate a repulsive force, and the repulsive force causes the first magnetic member 21 to move toward the second magnetic member 23, so that the first magnetic member 21 and the second magnetic member 23 cooperate to generate a first attractive force.

[0054] Specifically, the current in the first direction is opposite to the current in the second direction. When the first adjustment member 31 passes the current in the first direction, it can be known from the right-hand screw rule that the side of the first adjustment member 31 close to the first magnetic member 21 is the N pole, and the side of the first adjustment member 31 away from the first magnetic member 21 is the S pole, so that when the electronic device 100 is in the unfolded state, the S pole of the first magnetic member 21 and the N pole of the first adjustment member 31 are attracted to each other, so that the distance from the first magnetic member 21 to the first surface 15 is X1, and at this time, the magnetic force of the first magnetic member 21 is not enough to attract external objects. When the first adjusting member 31 passes a current in the second direction, it can be seen from the right-hand screw rule that the magnetic pole of the first adjusting member 31 changes, and the side of the first adjusting member 31 close to the first magnetic member 21 is the S pole, and the side of the first adjusting member 31 away from the first magnetic member 21 is the N pole. Therefore, when the electronic device 100 is in a folded state, the S pole of the first magnetic member 21 and the S pole of the first adjusting member 31 repel each other, and the repulsive force causes the first magnetic member 21 to move toward the first surface 15, and the first magnetic member 21 and the second magnetic member 23 cause the first sub-portion 11 and the second sub-portion 13 to be attracted together due to the first attractive force.

[0055] See also Figure 6 In some other embodiments, the first adjusting member 31 is an elastic connecting member, and the first magnetic member 21 is connected to one end of the connecting member. When the electronic device 100 is in the unfolded state, the connecting member makes the first distance X1 between the first magnetic member 21 and the first surface 15 greater than the first preset distance X0; when the electronic device 100 is in the folded state, the first attractive force pulls the first magnetic member 21 and drives the connecting member to deform, so that the first magnetic member 21 moves toward the second magnetic member 23.

[0056] Specifically, the connector is a structure used to connect and limit the position of other elements and can be deformed when subjected to external force, and can restore the original position when the external force disappears. The connector can be, but is not limited to, a component such as a paddle or a spring. One end of the connector is mounted on the first bracket 40, and the other end of the connector is connected to the first magnetic member 21. The number of connectors may be one or more. In the case where there is one connector, the connector can be installed at any position of the first bracket 40, as long as the other end of the connector can be connected to the first magnetic member 21. In the case where there are multiple connectors, multiple connectors can be arranged on one side of the first magnetic member 21, and multiple magnetic members can also be evenly or unevenly arranged on opposite sides of the first magnetic member 21.

[0057] The first adjusting member 31 of this embodiment is used to limit the position of the first magnetic member 21 when the electronic device 100 is in the unfolded state, so that the first distance between the first magnetic member 21 and the first surface 15 is X1. At this time, the magnetic force of the first magnetic member 21 is not enough to attract external objects. When the electronic device 100 is in the folded state, the first attraction between the first magnetic member 21 and the second magnetic member 23 pulls the first magnetic member 21 toward the first surface 15, thereby causing the connecting member to deform. When the first magnetic member 21 and the second magnetic member 23 generate the first attraction, the first adjusting member 31 is deformed. When the first attraction between the first magnetic member 21 and the second magnetic member 23 disappears, the first adjusting member 31 can drive the first magnetic member 21 to return to its original position.

[0058] See also Figure 7In other embodiments, the first adjusting member 31 is a resilient member, and the first magnetic member 21 is at least partially sunken into the resilient member. The resilient member applies a resilient force to the first magnetic member 21 that pulls the first magnetic member 21 toward the second surface 17. When the electronic device 100 is in the unfolded state, the resilient force causes the first magnetic member 21 to sink into the resilient member to a depth of H1, that is, the first distance X1 between the first magnetic member 21 and the first surface 15 is greater than the first preset distance X0. When the electronic device 100 is in the folded state, the first attractive force pulls the first magnetic member 21 toward the second magnetic member 23, and causes the first magnetic member 21 to sink into the resilient member to a depth of H2, wherein H2

[0059] Specifically, the resilient member is a structure that can generate friction with other elements to limit the movement of other elements. The material of the resilient member can be, but is not limited to, foam or silicone, etc. There is friction between the resilient member and the first magnetic member 21 in the present application. The resilient member and the first magnetic member 21 are installed on the same side of the first bracket 40. In one embodiment, the resilient member is a structure with an opening at one end close to the first surface 15 and a groove provided inside. The first magnetic member 21 is located in the groove of the resilient member, and the resilient member and the first magnetic member 21 generate friction. In another embodiment, the resilient member is a structure with openings at both ends and a through hole provided inside. The first magnetic member 21 is located in the through hole of the resilient member, and the resilient member and the first magnetic member 21 generate friction.

[0060] When the electronic device 100 is in the unfolded state, the friction between the first adjusting member 31 and the first magnetic member 21 is toward the second surface 17, so that the first distance between the first magnetic member 21 and the first surface 15 is X1. At this time, the magnetic force of the first magnetic member 21 is not enough to attract external objects. When the electronic device 100 is in the folded state, the first attraction between the first magnetic member 21 and the second magnetic member 23 is greater than the friction between the first adjusting member 31 and the first magnetic member 21. The first attraction pulls the first magnetic member 21 toward the first surface 15. The first magnetic member 21 and the second magnetic member 23 attract the first sub-portion 11 and the second sub-portion 13 due to the first attraction.

[0061] See also Figure 8 In some other embodiments, the first adjusting member 31 is a driving member, which is connected to the first magnetic member 21. When the electronic device 100 is in the unfolded state, the driving member drives the first magnetic member 21 to move until the first distance X1 between the first magnetic member 21 and the first surface 15 is greater than the first preset distance X0; when the electronic device 100 is in the folded state, the driving member is used to drive the first magnetic member 21 to move toward the second magnetic member 23.

[0062] ​Specifically, the driving member is a structure used to drive other components to move. The driving member of the present application is used to drive the first magnetic member 21 to move relative to the first bracket 40. The driving member can be a linear motor, a piezoelectric motor, a telescopic cylinder, etc. The driving member drives the first magnetic member 21 to move away from or close to the first surface 15 by telescoping. The driving member and the first magnetic member 21 are installed on the same side of the first bracket 40. One end of the driving member is fixedly connected to the first bracket 40, and the other end is connected to the first magnetic member 21 to drive the first magnetic member 21 to move relative to the first bracket 40.

[0063] When the electronic device 100 is in the unfolded state, the first adjusting member 31 drives the first magnetic member 21 to move toward the second surface 17 or limits the position of the first magnetic member 21, so that the first distance between the first magnetic member 21 and the first surface 15 is X1, at which time the magnetic force of the first magnetic member 21 is insufficient to attract external objects. When the electronic device 100 is in the folded state, the first adjusting member 31 drives the first magnetic member 21 to move toward the first surface 15, and the first magnetic member 21 and the second magnetic member 23 attract the first sub-portion 11 and the second sub-portion 13 due to the first attraction.

[0064] See also Figure 2 In some embodiments, the electronic device 100 further includes a second bracket 50, which is disposed in the body 10, and the second magnetic member 23 is movably mounted on the second bracket 50. The second bracket 50 is a structure for mounting and connecting other components, and the second bracket 50 of the present application is used to mount and support the second magnetic member 23 and connect the second adjusting member 33. The second bracket 50 is disposed in the second sub-portion 13, and corresponds to the positions of the second magnetic member 23 and the second adjusting member 33. In one embodiment, the first bracket 40 and the second bracket 50 are an integral structure, and the first bracket 40 and the second bracket 50 can rotate relative to each other. In another embodiment, the first bracket 40 and the second bracket 50 are split structures, and the first bracket 40 and the second bracket 50 are spaced apart in the body 10.

[0065] In some embodiments, when the electronic device 100 is in a folded state, the second magnetic member 23 is at a fourth distance Y2 from the first surface 15, and the fourth distance Y2 is equal to the second distance Y1. When the fourth distance Y2 is equal to the second distance Y1, the second magnetic member 23 is fixedly mounted on the second bracket 50, and the second magnetic member 23 is fixed relative to the second bracket 50. The distance between the second magnetic member 23 and the first surface 15 is always maintained at Y1, and the magnetic force of the second magnetic member 23 is insufficient to attract external objects when the electronic device 100 is in a folded state. When the electronic device 100 is in an unfolded state, the first magnetic member 21 moves relative to the second magnetic member 23 to attract the second magnetic member 23 to generate a first attraction force, so that the first sub-portion 11 and the second sub-portion 13 are attracted.

[0066] See also Figure 2 In other embodiments, when the electronic device 100 is in a folded state, the second magnetic member 23 is at a fourth distance Y2 from the first surface 15, and the fourth distance Y2 is less than the second distance Y1. When the fourth distance Y2 is less than the second distance Y1, the second magnetic member 23 is movably mounted on the second bracket 50. When the electronic device 100 is in an unfolded state, the distance between the second magnetic member 23 and the first surface 15 is Y1. At this time, the magnetic force of the second magnetic member 23 is not sufficient to attract external objects. When the electronic device 100 is in a folded state, the first magnetic member 21 moves toward the first surface 15, and the second magnetic member 23 moves toward the second surface 17. The first magnetic member 21 and the second magnetic member 23 attract each other to generate a first attraction force, so that the first sub-portion 11 and the second sub-portion 13 are attracted together. In the case where the second magnetic member 23 can move relative to the second bracket 50, the adjustment assembly 30 further includes a second adjustment member 33 disposed on the second sub-portion 13, the second adjustment member 33 is fixedly connected to the second bracket 50, the second adjustment member 33 corresponds to the second magnetic member 23, and the second adjustment member 33 is used to adjust the distance between the second magnetic member 23 and the first surface 15. The second adjustment member 33 is disposed on a side of the second magnetic member 23 away from the first surface 15, and the second adjustment member 33 can act on the second magnetic member 23 in a contacting or non-contacting manner to adjust the distance of the second magnetic member 23 relative to the first surface 15.

[0067] See also Figure 2 In some embodiments, the second adjusting member 33 is a magnetic member, and the second adjusting member 33 cooperates with the second magnetic member 23 to generate a third attraction, the first attraction is greater than the third attraction, and when the electronic device 100 is in the unfolded state, the third attraction is used to make the second distance Y1 between the second magnetic member 23 and the first surface 15 greater than the second preset distance Y0, and when the electronic device 100 is in the folded state, the first attraction is used to pull the second magnetic member 23 toward the first magnetic member 21.

[0068] Specifically, the magnetic part is a structure that attracts other components through its own magnetic field. The magnetic part can be a magnet or other magnetic objects. The magnetic part can be installed on the same side of the second bracket 50 as the second magnetic part 23, or on the opposite side of the second bracket 50 and the second magnetic part 23, as long as the magnetic part can generate a third attractive force with the second magnetic part 23. The magnetic part can be installed on the second bracket 50 by methods such as dispensing or welding.

[0069] In one embodiment, the second adjusting member 33 and the second magnetic member 23 are different magnets. In another embodiment, the second adjusting member 33 and the second magnetic member 23 are the same magnet. In yet another embodiment, the second magnetic member 23 and the first magnetic member 21 are different magnets. In yet another embodiment, the second magnetic member 23 and the first magnetic member 21 are the same magnet. The side of the second adjusting member 33 close to the second magnetic member 23 is the S pole, and the side of the second adjusting member 33 away from the second magnetic member 23 is the N pole, so that when the electronic device 100 is in the unfolded state, the N pole of the second magnetic member 23 and the S pole of the second adjusting member 33 are attracted to each other, so that the distance from the second magnetic member 23 to the first surface 15 is Y1. At this time, the magnetic force of the second magnetic member 23 is not enough to attract external objects. According to the formula F=K / R 2 It can be known that the magnetic attraction force F is proportional to the magnetic field strength K, and the magnetic attraction force F is inversely proportional to the distance R. In one embodiment, the size of the first magnetic member 21 and the second magnetic member 23 is larger than the size of the first adjusting member 31 and the second adjusting member 33, so that when the electronic device 100 is in a folded state, the first attraction is greater than the second attraction and the third attraction. In another embodiment, when the electronic device 100 is in a folded state, the distance between the first magnetic member 21 and the second magnetic member 23 is smaller than the distance between the first magnetic member 21 and the first adjusting member 31 and the distance between the second magnetic member 23 and the second adjusting member 33, so that the first attraction is greater than the second attraction and the third attraction. The size of the first magnetic member 21 and the second magnetic member 23 in the embodiment of the present application is larger than the size of the first adjusting member 31 and the second adjusting member 33, so that the first attraction is greater than the second attraction and the third attraction.

[0070] See also Figure 3 In some other embodiments, the second adjusting member 33 is an electromagnet. When the electronic device 100 is in the unfolded state, the second adjusting member 33 is energized to cooperate with the second magnetic member 23 to generate a third attractive force, and the third attractive force is used to make the second distance Y1 between the second magnetic member 23 and the first surface 15 greater than the second preset distance Y0; when the electronic device 100 is in the folded state, the second adjusting member 33 is de-energized, and the first attractive force pulls the second magnetic member 23 toward the first magnetic member 21.

[0071] Specifically, the electromagnet is a structure that generates magnetic force when powered on to attract or repel other elements. The electromagnet of the present application is used to generate magnetic force when powered on to attract or repel the first magnetic member 21. The electromagnet can be installed on the same side of the second bracket 50 as the second magnetic member 23, or the electromagnet can be installed on the opposite side of the second bracket 50 from the second magnetic member 23, as long as the electromagnet can generate the third attractive force with the second magnetic member 23.

[0072] When the power is on, according to the direction of the current, it can be known from the right-hand screw rule that the side of the second adjusting member 33 close to the second magnetic member 23 is the S pole, and the side of the second adjusting member 33 away from the second magnetic member 23 is the N pole, so that when the electronic device 100 is in the unfolded state, the N pole of the second magnetic member 23 and the S pole of the second adjusting member 33 attract each other, so that the distance from the second magnetic member 23 to the first surface 15 is Y1, and at this time, the magnetic force of the second magnetic member 23 is not enough to attract external objects. When the power is off, the second adjusting member 33 has no magnetic force, and there is no attraction between the second adjusting member 33 and the second magnetic member 23, so that when the electronic device 100 is in the folded state, the first magnetic member 21 and the second magnetic member 23 attract the first sub-section 11 and the second sub-section 13 due to the first attraction.

[0073] See also Figure 4 In some other embodiments, the second adjusting member 33 is an electromagnet. When the electronic device 100 is in the unfolded state, the second adjusting member 33 is powered off, and the second distance Y1 between the second magnetic member 23 and the first surface 15 is greater than the second preset distance Y0. When the electronic device 100 is in the folded state, the second adjusting member 33 is powered on to cooperate with the second magnetic member 23 to generate a repulsive force, and the repulsive force causes the second magnetic member 23 to move toward the first magnetic member 21, so that the second magnetic member 23 cooperates with the first magnetic member 21 to generate a first attractive force.

[0074] Specifically, when the power is off, the second adjusting member 33 has no magnetic force, and there is no attraction between the second adjusting member 33 and the second magnetic member 23. When the electronic device 100 is in the unfolded state, the second magnetic member 23 is placed on the second bracket 50, and the distance from the second magnetic member 23 to the first surface 15 is Y1. At this time, the magnetic force of the second magnetic member 23 is not enough to attract external objects. When the power is on, according to the direction of the current, it can be known from the right-hand screw rule that the side of the second adjusting member 33 close to the second magnetic member 23 is the N pole, and the side of the second adjusting member 33 away from the second magnetic member 23 is the S pole, so that when the electronic device 100 is in the folded state, the N pole of the second magnetic member 23 and the N pole of the second adjusting member 33 repel each other, and the repulsive force causes the second magnetic member 23 to move toward the first surface 15, and the first magnetic member 21 and the second magnetic member 23 attract the first sub-section 11 and the second sub-section 13 due to the first attraction.

[0075] See also Figure 5In some further embodiments, the second adjusting member 33 is an electromagnet. When the electronic device 100 is in the unfolded state, the second adjusting member 33 passes current in the first direction to cooperate with the second magnetic member 23 to generate a third attractive force, and the third attractive force is used to make the second distance Y1 between the second magnetic member 23 and the first surface 15 greater than the second preset distance Y0; when the electronic device 100 is in the folded state, the second adjusting member 33 passes current in the second direction to cooperate with the second magnetic member 23 to generate a repulsive force, and the repulsive force causes the second magnetic member 23 to move toward the first magnetic member 21, so that the second magnetic member 23 cooperates with the first magnetic member 21 to generate the first attractive force.

[0076] Specifically, the current in the first direction is opposite to the current in the second direction. When the second adjusting member 33 passes the current in the first direction, it can be known from the right-hand screw rule that the side of the second adjusting member 33 close to the second magnetic member 23 is the S pole, and the side of the second adjusting member 33 away from the second magnetic member 23 is the N pole, so that when the electronic device 100 is in the unfolded state, the N pole of the second magnetic member 23 and the S pole of the second adjusting member 33 are attracted to each other, so that the distance from the second magnetic member 23 to the first surface 15 is Y1, and at this time, the magnetic force of the second magnetic member 23 is not enough to attract external objects. When the second adjusting member 33 passes a current in the second direction, it can be seen from the right-hand screw rule that the magnetic pole of the second adjusting member 33 changes, and the side of the second adjusting member 33 close to the second magnetic member 23 is the N pole, and the side of the second adjusting member 33 away from the second magnetic member 23 is the S pole. Therefore, when the electronic device 100 is in a folded state, the N pole of the second magnetic member 23 repels the N pole of the second adjusting member 33, and the repulsive force causes the second magnetic member 23 to move toward the first surface 15. The first magnetic member 21 and the second magnetic member 23 attract each other due to the first attraction.

[0077] See also Figure 6 In some other embodiments, the second adjusting member 33 is an elastic connecting member, and the second magnetic member 23 is connected to one end of the connecting member. When the electronic device 100 is in the unfolded state, the connecting member makes the second distance Y1 between the second magnetic member 23 and the first surface 15 greater than the second preset distance Y0; when the electronic device 100 is in the folded state, the first attractive force pulls the second magnetic member 23 and drives the connecting member to deform, so that the second magnetic member 23 moves toward the first magnetic member 21.

[0078] Specifically, the connector is a structure used to connect and limit the position of other elements and can be deformed when subjected to external force, and can restore the original position when the external force disappears. The connector can be, but is not limited to, a component such as a paddle or a spring. One end of the connector is mounted on the second bracket 50, and the other end of the connector is connected to the second magnetic member 23. The number of connectors may be one or more. In the case where there is one connector, the connector can be installed at any position of the second bracket 50, as long as the other end of the connector can be connected to the second magnetic member 23. In the case where there are multiple connectors, multiple connectors can be arranged on one side of the second magnetic member 23, and multiple magnetic members can also be evenly or unevenly arranged on opposite sides of the second magnetic member 23.

[0079] The second adjusting member 33 of this embodiment is used to limit the position of the second magnetic member 23 when the electronic device 100 is in the unfolded state, so that the second distance between the second magnetic member 23 and the first surface 15 is Y1, at which time, the magnetic force of the second magnetic member 23 is not enough to attract external objects. When the electronic device 100 is in the folded state, the first attraction between the first magnetic member 21 and the second magnetic member 23 pulls the second magnetic member 23 toward the first surface 15, thereby causing the connector to deform. When the first magnetic member 21 and the second magnetic member 23 generate the first attraction, the second adjusting member 33 is deformed. When the first attraction between the first magnetic member 21 and the second magnetic member 23 disappears, the second adjusting member 33 can drive the second magnetic member 23 to return to its original position.

[0080] See also Figure 7 In other embodiments, the second adjusting member 33 is a resilient member, and the second magnetic member 23 is at least partially sunken into the resilient member. The resilient member applies a resilient force to the second magnetic member 23 that pulls the second surface 17. When the electronic device 100 is in the unfolded state, the resilient force causes the second magnetic member 23 to sink into the resilient member to a depth of H3, that is, the second distance Y1 between the second magnetic member 23 and the first surface 15 is greater than the second preset distance Y0. When the electronic device 100 is in the folded state, the first attractive force pulls the second magnetic member 23 toward the first magnetic member 21, and causes the first magnetic member 21 to sink into the resilient member to a depth of H4, wherein H4<H3.

[0081] Specifically, the resilient member is a structure that can generate friction with other elements to limit the movement of other elements. The material of the resilient member can be, but is not limited to, foam or silicone, etc. There is friction between the resilient member and the second magnetic member 23 in the present application. The resilient member and the second magnetic member 23 are installed on the same side of the second bracket 50. In one embodiment, the resilient member is a structure with an opening at one end close to the first surface 15 and a groove provided inside. The second magnetic member 23 is located in the groove of the resilient member, and the resilient member and the second magnetic member 23 generate friction. In another embodiment, the resilient member is a structure with openings at both ends and a through hole provided inside. The second magnetic member 23 is located in the through hole of the resilient member, and the resilient member and the second magnetic member 23 generate friction.

[0082] When the electronic device 100 is in the unfolded state, the friction between the second adjusting member 33 and the second magnetic member 23 is toward the second surface 17, so that the second distance between the second magnetic member 23 and the second surface 17 is Y1. At this time, the magnetic force of the second magnetic member 23 is not enough to attract external objects. When the electronic device 100 is in the folded state, the first attraction between the first magnetic member 21 and the second magnetic member 23 is greater than the friction between the second adjusting member 33 and the second magnetic member 23. The first attraction pulls the second magnetic member 23 toward the first surface 15. The first magnetic member 21 and the second magnetic member 23 attract the first sub-portion 11 and the second sub-portion 13 due to the first attraction.

[0083] See also Figure 8 In some other embodiments, the second adjusting member 33 is a driving member, which is connected to the second magnetic member 23. When the electronic device 100 is in the unfolded state, the driving member drives the second magnetic member 23 to move to a second distance Y1 between the second magnetic member 23 and the first surface 15 that is greater than the second preset distance Y0; when the electronic device 100 is in the folded state, the driving member is used to drive the second magnetic member 23 to move toward the first magnetic member 21.

[0084] Specifically, the driving member is a structure used to drive other elements to move. The driving member of the present application is used to drive the second magnetic member 23 to move relative to the second bracket 50. The driving member can be a linear motor, a piezoelectric motor, a telescopic cylinder, etc. The driving member drives the second magnetic member 23 to move away from or close to the first surface 15 by telescoping. The driving member and the second magnetic member 23 are installed on the same side of the second bracket 50. One end of the driving member is fixedly connected to the second bracket 50, and the other end is connected to the second magnetic member 23 to drive the second magnetic member 23 to move relative to the second bracket 50.

[0085] When the electronic device 100 is in the unfolded state, the second adjusting member 33 drives the second magnetic member 23 to move toward the second surface 17 or limits the position of the first magnetic member 21, so that the second distance between the second magnetic member 23 and the first surface 15 is Y1, at which time the magnetic force of the second magnetic member 23 is insufficient to attract external objects. When the electronic device 100 is in the folded state, the second adjusting member 33 drives the second magnetic member 23 to move toward the first surface 15, and the first magnetic member 21 and the second magnetic member 23 attract the first sub-portion 11 and the second sub-portion 13 due to the first attraction.

[0086] In one embodiment, the first adjusting member 31 and the second adjusting member 33 are the same. For example, when the first adjusting member 31 is a magnetic member, the second adjusting member 33 is also a magnetic member; for another example, when the first adjusting member 31 is an electromagnet, the second adjusting member 33 is also an electromagnet; for another example, when the first adjusting member 31 is an elastic connecting member, the second adjusting member 33 is also an elastic connecting member, and so on, which are not listed one by one here. In another embodiment, the first adjusting member 31 and the second adjusting member 33 are different. For example, when the first adjusting member 31 is a magnetic member, the second adjusting member 33 is at least one of an electromagnet, an elastic connecting member, a rebound member, and a driving member; for another example, when the first adjusting member 31 is an electromagnet, the second adjusting member 33 is at least one of a magnetic member, an elastic connecting member, a rebound member, and a driving member, and so on, which are not listed one by one here.

[0087] For further information, see Figure 2 In some embodiments, the electronic device 100 also includes a display screen 60, which is disposed on a side of the first surface 15 of the main body 10, and the display screen 60 includes a first display area 61 located in the first sub-section 11 and a second display area 63 located in the second sub-section 13. In the thickness direction of the main body 10, the first magnetic member 21 is located between the first display area 61 and the second surface 17, and the second magnetic member 23 is located between the second display area 63 and the second surface 17.

[0088] The display screen 60 may be a flexible display screen 60 to realize the folding of the electronic device 100, and the first display area 61 and the second display area 63 may rotate relative to each other. The first bracket 40, the first magnetic member 21 and the first adjusting member 31 are located between the first display area 61 and the second surface 17, and the second bracket 50, the second magnetic member 23 and the second adjusting member 33 are located between the second display area 63 and the second surface 17. When the electronic device 100 is in the unfolded state, the first magnetic member 21 is spaced from the first display area 61, and the second magnetic member 23 is spaced from the second display area 63. When the electronic device 100 is in the folded state, due to the traction of the first attractive force, the first magnetic member 21 moves relative to the first bracket 40 and can contact the first display area 61, and the second magnetic member 23 moves relative to the second bracket 50 and can contact the second display area 63, so that the first sub-section 11 and the second sub-section 13 are attracted.

[0089] See also Figure 1 Furthermore, in some embodiments, the electronic device 100 further includes a detector 70 and a processor 80. The detector 70 is disposed on the body 10, and the detector 70 is used to detect the angle between the first sub-section 11 and the second sub-section 13. The processor 80 is disposed on the body 10, and the processor 80 is used to determine whether the electronic device 100 is in a folded state or an unfolded state according to the angle.

[0090] The detector 70 and the processor 80 are arranged in the body 10, and the detector 70 is arranged at the connection between the first sub-section 11 and the second sub-section 13, and the detector 70 can be an angle sensor. The detector 70 detects the angle between the first surface 111 of the first sub-section 11 and the first surface 131 of the second sub-section 13, and feeds back the detection information to the processor 80, and the processor 80 judges the folding or unfolding state of the electronic device 100 to send a control signal. In the case where the first adjustment member 31 is an electromagnet, the control signal controls the electromagnet to be powered on or off, and the control signal can also control the direction of the current flowing into the electromagnet. In the case where the first adjustment member 31 is a driving member, the control signal can control the driving member to drive the first magnetic member 21 to move toward the first surface 15 or the second surface 17. In the case where the second adjustment member 33 is an electromagnet, the control signal can control the electromagnet to be powered on or off, and the control signal can also control the direction of the current flowing into the electromagnet. In the case where the second adjustment member 33 is a driving member, the control signal can control the driving member to drive the first magnetic member 21 to move toward the first surface 15 or the second surface 17.

[0091] In summary, when the electronic device 100 is in the unfolded state, the distance between the first magnetic member 21 and the second magnetic member 23 and the first surface 15 is greater than X0, and the magnetic force of the first magnetic member 21 and the second magnetic member 23 is insufficient to attract external objects. When the electronic device 100 is in the folded state, the first magnetic member 21 and the second magnetic member 23 attract each other to make the first sub-section 11 and the second sub-section 13 close together.

[0092] In the electronic device 100 of the present application, when the electronic device 100 is in a folded state, the first magnetic member 21 is adjusted by the first adjusting member 31 so that the first magnetic member 21 is close to the first surface 15, and the first magnetic member 21 and the second magnetic member 23 attract each other, so that the first sub-section 11 and the second sub-section 13 are attracted. When the electronic device 100 is in an unfolded state, the first magnetic member 21 is adjusted by the first adjusting member 31 so that the first magnetic member 21 is away from the first surface 15, and the magnetic force of the first magnetic member 21 is not enough to absorb foreign objects. The distance from the second magnetic member 23 to the first surface 15 also makes the magnetic force of the second magnetic member 23 not enough to absorb foreign objects. The magnetic component 20 is not enough to absorb foreign objects when the electronic device 100 is in an unfolded state, so that the electronic device 100 will not be crushed and damaged by the adsorbed foreign objects on the surface of the electronic device 100 when it is in a folded state.
