Description

Electronic device comprising a magnetic assembly

[0001] Various embodiments disclosed in this document relate to electronic devices including a magnet assembly.

[0002] As the amount of information displayed visually increases and electronic devices support more functions, users are increasingly demanding larger displays. New types of electronic devices are also being developed to provide large displays while maintaining a portable size.

[0003] Advances in display technology have made foldable displays possible. Electronic devices utilizing these displays, whose display area can be adjusted by folding, are also being released.

[0004] A foldable electronic device can be configured to fold or unfold by having two housings joined together via a hinge mechanism. Magnets may be positioned within each housing to maintain the foldable electronic device in a fully folded state. The magnets within each housing may be positioned with opposite polarities when the electronic device is folded, thereby creating an attractive force between the magnets. Accordingly, the foldable electronic device can maintain its folded state through the magnets. The more closely the magnets within each housing are positioned relative to each other, the greater the attractive force between the magnets.

[0005] Meanwhile, as various electronic components are placed within an electronic device, magnets of limited size may be placed within the device. Furthermore, the various electronic components placed within the device may cause the magnets placed within each housing to not face each other or to only partially face each other when the device is folded. Consequently, the strength of the attractive force between the magnets is reduced, potentially leading to the device unfolding unintentionally from a folded state.

[0006] According to one embodiment of the present disclosure, when the electronic device is folded, the strength of the attractive force acting between the magnets can be increased even if the magnets arranged in each housing do not correspond to each other.

[0007] According to one embodiment of the present disclosure, an electronic device may include a first housing. In one embodiment, the electronic device may include a second housing rotatably connected to the first housing about a folding axis. In one embodiment, the electronic device may include a display disposed on a front surface of the electronic device, a portion of which is deformed by rotation of the second housing relative to the first housing. In one embodiment, the electronic device may include a first magnet disposed in the first housing, and a second magnet disposed in the second housing so as not to correspond to the first magnet when the electronic device is folded, and having an attractive force with the first magnet. The first magnet may include a first boundary surface defining different poles and inclined at a first angle with respect to the folding axis, and the second magnet may include a second boundary surface defining different poles and inclined at a second angle with respect to the folding axis, and the first boundary surface and the second boundary surface may face each other.

[0008] According to one embodiment of the present disclosure, a magnet assembly disposed in an electronic device in which a first housing and a second housing are rotatably connected about a folding axis may include a first magnet disposed in the first housing and a second magnet disposed in the second housing so as not to correspond to the first magnet when the electronic device is folded and having an attractive force with the first magnet. The first magnet may include a first boundary surface defining different poles and inclined at a first angle with respect to the folding axis, and the second magnet may include a second boundary surface defining different poles and inclined at a second angle with respect to the folding axis, and the first boundary surface and the second boundary surface may face each other.

[0009] According to one embodiment of the present disclosure, when the magnets arranged in each housing are spaced apart from each other in a folded state of the electronic device, a certain level of strength of the attractive force acting between the magnets can be secured.

[0010] For example, if the magnets placed in each housing are arranged so that only some of the magnets correspond to each other, the strength of the attractive force acting between the magnets can be increased by forming the boundary surfaces that divide the N and S poles of each magnet to face each other.

For example, the second magnet assembly may include the second magnet (220) illustrated in FIG. 3A, the fourth magnet (240) illustrated in FIG. 6A, and the first magnet (320) illustrated in FIG. 9A (e.g., a Halbach magnet). Hereinafter, when the electronic device (100) is folded, the attractive force acting between the first magnet assembly and the second magnet assembly will be described using the first magnet (210) and the second magnet (220) illustrated in FIGS. 3A and 3B.

[0054] In one embodiment, the first magnet (210) and the second magnet (220) may exert an attractive force as the electronic device (100) transitions from an unfolded state to a folded state. The electronic device (100) may maintain the folded state through an attractive force acting between the first magnet (210) disposed in the first housing (110) and the second magnet (220) disposed in the second housing (120). In one embodiment, the strength of the attractive force acting between the first magnet (210) and the second magnet (220) may be greater than the strength of the repulsive force generated when the display (130) is folded when the electronic device (100) is folded.

[0055] In one embodiment, referring to FIG. 6A described below, the electronic device (100) may include a first magnet (210), a third magnet (230) disposed in a first housing (110), a second magnet (220) disposed in a second housing (120), and a fourth magnet (240). In one embodiment, the first magnet (210) and the third magnet (230) may be positioned adjacent to each other, and the second magnet (220) and the fourth magnet (240) may be positioned adjacent to each other. However, the above description may not limit the number of magnets included in the first housing (110) and the second housing (120). The electronic device (100) may omit any one of the first magnet (210), the second magnet (220), the third magnet (230), and the fourth magnet (240) or may further include another magnet.

[0056] In one embodiment, at least one of the plurality of first magnets (210) may be positioned at an edge of the first housing (110) so as to be adjacent to a first side member (113) disposed in the first housing (110). For example, at least one of the plurality of first magnets (210) may be positioned at an edge of the first housing (110). At least one of the plurality of second magnets (220) may be positioned at an edge of the second housing (120) so as to be adjacent to a second side member (123) disposed in the second housing (120). For example, at least one of the plurality of second magnets (220) may be positioned at an edge of the second housing (120). The moment required to maintain the electronic device (100) in a folded state may be the same at any point of the electronic device (100). For example, the moment required to maintain the electronic device (100) in a folded state may be the same at the edge of the electronic device (100) and at the center of the electronic device (100). Accordingly, the first magnet (210) and the second magnet (220) are positioned adjacent to the side members (113, 123) and can maintain the folded state of the electronic device (100) with a smaller force than when they are positioned adjacent to the hinge device (HA) located at the center of the electronic device (100).

[0057] Hereinafter, for convenience of explanation, one of the plurality of first magnets (210) and one of the plurality of second magnets (220) illustrated in FIG. 3a will be described. For example, this may be a description of the relationship between the first magnet (210) and the second magnet (220) located at the outermost position in the -X direction based on FIG. 3a. Alternatively, this may be a description of the relationship between the first magnet (210) and the second magnet (220) located at the outermost position in the +X direction based on FIG. 3a. The contents to be described below may be equally applied to the plurality of first magnets (210) arranged in the first housing (110) and the plurality of second magnets (220) arranged in the second housing (120).

[0058] In one embodiment, referring to FIGS. 3A and 3B , the first magnet (210) and the second magnet (220) may be arranged such that their opposite poles face each other. For example, the north pole of the first magnet (210) may face the display (130), and the south pole of the second magnet (220) may face the display (130). Conversely, the south pole of the first magnet (210) may face the display (130), and the north pole of the second magnet (220) may face the display (130). The electronic device (100) may be maintained in a folded state through the attractive force acting between the first magnet (210) and the second magnet (220).

[0059] In one embodiment, the magnets disposed in the first housing (110) and the magnets disposed in the second housing (120) may be formed in various shapes. Referring to FIGS. 3A and 3B in one embodiment, the plurality of first magnets (210) and the plurality of second magnets (220) that face each other when the electronic device (100) is folded may be formed in different shapes. In an example not shown in the drawings, the plurality of first magnets (210) and the plurality of second magnets (220) may be formed in the same shape. In addition, in one embodiment, the first magnet (210), the second magnet (220), the third magnet (230), and / or the fourth magnet (240) described below may be formed in the same shape. In one embodiment, the first magnet (210), the second magnet (220), the third magnet (230), and / or the fourth magnet (240) may be formed in different shapes.

[0060] According to one embodiment, the magnetic force of a magnetic field generated by a magnet (e.g., a first magnet (210), a second magnet (220), a third magnet (230), and / or a fourth magnet (240)) may be proportional to the density of magnetic flux per unit area.

[0061] Hereinafter, a virtual axis extending in a direction perpendicular to the display (130) and passing through the N pole and the S pole of the first magnet (210) will be described as a first axis (C1) (e.g., the first axis (C1) of FIG. 3b). In addition, a virtual axis extending in a direction perpendicular to the display (130) and passing through the N pole and the S pole of the second magnet (220) will be described as a second axis (C2) (e.g., the second axis (C2) of FIG. 3b). The first axis (C1) and the second axis (C2) described above are virtual axes, and the first axis (C1) of the first magnet (210) may be an axis for describing a location where the magnetic force of the first magnetic field (M1) of the first magnet (210) is relatively strong among the first point, the second point, and the third point of FIGS. 4b and 4c. In addition, the second axis (C2) of the second magnet (220) may be an axis for explaining a location where the magnetic force of the second magnetic field (M2) of the second magnet (220) is relatively strong among the fourth, fifth, and sixth points of FIGS. 4B and 4C. For example, referring to FIGS. 4B and 4C, which will be described later, it can be confirmed that the magnetic force of the first magnet (210) is the strongest at 1100 G (gauss) at the second point closest to the first axis (C1) among the first, second, and third points. Similarly, the magnetic force of the second magnetic field (M2) generated in the second magnet (220) may become stronger as it approaches the second axis (C2). For example, referring to FIGS. 4b and 4c described later, it can be confirmed that the magnetic field strength of the second magnet (220) is the strongest at 1100 G at the fifth point among the fourth, fifth, and sixth points.

[0062] In one embodiment, the attractive force acting between the first magnet (210) and the second magnet (220) may be proportional to the strength of the magnetic field. For example, the greater the degree of overlap between the first magnetic field (M1) of the first magnet (210) and the second magnetic field (M2) of the second magnet (220), the greater the strength of the attractive force acting between the first magnet (210) and the second magnet (220).

[0063] According to one embodiment, as illustrated in FIG. 3B, the first magnet (210) disposed in the first housing (110) and the second magnet (220) disposed in the second housing (120) may be disposed so as not to correspond to each other when the electronic device (100) is folded. For example, referring to FIG. 3B, the first magnet (210) may partially overlap the second magnet (220) when viewed in a direction perpendicular to the display (130) (e.g., in the Z-axis direction with reference to FIG. 2A) when the electronic device (100) is folded. In one embodiment not illustrated in the drawing, the first magnet (210) may not overlap the second magnet (220) when viewed in a direction perpendicular to the display (130) when the electronic device (100) is folded. Accordingly, the strength of the attractive force acting between the first magnet (210) and the second magnet (220) may be reduced. In this case, the electronic device (100) may be unfolded regardless of the user's intention while the electronic device (100) is folded.

[0064] In one embodiment, the first magnet (210) and the second magnet (220) may be formed in different shapes so that they do not correspond to each other when the electronic device (100) is folded. According to one embodiment, various electronic components may be arranged inside the electronic device (100). In this case, the space in which the first magnet (210) and the second magnet (220) may be arranged within the first housing (110) and the second housing (120) may be limited. In this case, the first magnet (210) and the second magnet (220) may be formed in different shapes and may be arranged so that they do not face each other or only partially face each other when the electronic device (100) is folded. Alternatively, even if the first magnet (210) and the second magnet (220) are formed in the same shape, the space in which they can be placed inside the first housing (110) and the second housing (120) is limited, so that the first magnet (210) and the second magnet (220) may not be placed in contact with each other. Accordingly, the strength of the attractive force acting between the first magnet (210) and the second magnet (220) may be reduced. In this case, the electronic device (100) may be unfolded regardless of the user's intention when the electronic device (100) is in a folded state.

[0065] According to one embodiment of the present disclosure, the strength of the attractive force acting between the first magnet (210) and the second magnet (220) that are arranged so as not to correspond to each other when the electronic device (100) is folded can be increased. For example, the strength of the attractive force acting between the first magnet (210) and the second magnet (220) can be increased by forming the boundary surface that divides the N pole and the S pole of the first magnet (210) (e.g., the first boundary surface (211) of FIG. 4b) and the boundary surface that divides the N pole and the S pole of the second magnet (220) (e.g., the second boundary surface (221) of FIG. 4b) to face each other. A specific description will be provided below.

[0066] FIG. 4A is a diagram illustrating an embodiment in which a first boundary surface of a first magnet and a second boundary surface of a second magnet are formed parallel to a folding axis according to one embodiment. FIG. 4B is a diagram explaining an attractive force acting between a first magnet and a second magnet according to an angle at which the first boundary surface of the first magnet illustrated in FIG. 3A is inclined with respect to the folding axis and an angle at which the second boundary surface of the second magnet is inclined with respect to the folding axis. FIG. 4C is a diagram illustrating an embodiment in which the first boundary surface of the first magnet is formed parallel to the folding axis according to one embodiment of the present disclosure. FIG. 4D is a diagram illustrating an attractive force between a first magnet and a second magnet according to an angle at which the first boundary surface and the second boundary surface of FIG. 4B are inclined with respect to the folding axis.

[0067] Hereinafter, FIGS. 4a and 4b will describe the first magnet (210) placed in the first housing (110) and the second magnet (220) placed in the second housing (120).

[0068] In one embodiment, FIG. 4B is a diagram schematically illustrating the positional relationship between the first magnet (210) and the second magnet (220) illustrated in FIG. 4A. In one embodiment, referring to FIG. 4A, the first magnet (210) and the second magnet (220) may be formed in different shapes.

[0069] In one embodiment, referring to FIG. 4B, the first magnet (210) and the second magnet (220) may be arranged so as not to correspond to each other when the electronic device (100) is folded. For example, the first axis (C1) of the first magnet (210) and the second axis (C2) of the second magnet (220) may not coincide.

[0070] According to one embodiment, as illustrated in FIG. 4B, the first magnet (210) and the second magnet (220) may include interfaces that define different poles (e.g., N pole and S pole). For example, the first magnet (210) may include a first interface (211) that defines the N pole and the S pole. The second magnet (220) may include a second interface (221) that defines the N pole and the S pole. In one embodiment, as the first magnetic field (M1) generated in the first magnet (210) is directed toward the second magnet (220) and the second magnetic field (M2) generated in the second magnet (220) is directed toward the first magnet (210), the strength of the attractive force acting between the first magnet (210) and the second magnet (220) may increase. For example, as the first boundary surface (211) of the first magnet (210) faces the second magnet (220), the amount of the magnetic flux of the first magnetic field (M1) generated in the first magnet (210) passing through the second magnet (220) increases, and thus the attractive force acting between the first magnet (210) and the second magnet (220) may increase. In addition, as the second boundary surface (221) of the second magnet (220) faces the first magnet (210), the amount of the magnetic flux of the second magnetic field (M2) generated in the second magnet (220) passing through the first magnet (210) may increase, and thus the attractive force acting between the first magnet (210) and the second magnet (220) may increase.

[0071] In one embodiment, as the area where the first boundary surface (211) and the second boundary surface (221) overlap increases, the amount of overlap between the first magnetic field (M1) generated from the first magnet (210) and the second magnetic field (M2) generated from the second magnet (220) increases, so that the strength of the attractive force acting between the first magnet (210) and the second magnet (220) may increase.

[0072] In one embodiment, referring to FIG. 4b, the first magnet (210) and the second magnet (220) can be formed such that the first boundary surface (211) and the second boundary surface (221) face each other. For example, the first magnet (210) may be formed so that the first boundary surface (211) is inclined at a first angle (θ) with respect to the folding axis (F) so as to face the second magnet (220) located opposite to the folding axis (F). The second magnet (220) may be formed so that the second boundary surface (221) is inclined at a second angle (θ) with respect to the folding axis (F) so as to face the first magnet (210) located opposite to the folding axis (F). In this case, the first magnetic field (M1) generated in the first magnet (210) may be directed toward the second magnet (220), and the second magnetic field (M2) generated in the second magnet (220) may be directed toward the first magnet (210). Accordingly, the first boundary surface (211) of the first magnet (210) and / or the second boundary surface (211) of the second magnet (220) Compared to the case where the boundary surface (221) is formed parallel to the folding axis (F), the amount of the magnetic flux of the first magnetic field (M1) generated from the first magnet (210) passing through the second magnet (220) may increase, and the amount of the magnetic flux of the second magnetic field (M2) generated from the second magnet (220) passing through the first magnetic flux may increase. Accordingly, the amount of overlap between the first magnetic field (M1) of the first magnet (210) and the second magnetic field (M2) of the second magnet (220) may increase. Accordingly, the attractive force acting between the first magnet (210) and the second magnet (220) may increase.

[0073] In one embodiment, the first magnet (210) and the second magnet (220) may have a magnetic field strength that varies depending on the position as the first boundary surface (211) and the second boundary surface (221) are inclined at a certain angle with respect to the folding axis (F). Referring to FIGS. 4B and 4C, the magnetic field strength depending on the relative position between the first magnet (210) and the second magnet (220) may be confirmed. In one embodiment, referring to FIG. 4B, the first magnetic field (M1) generated from the first magnet (210) may be measured to have a magnetic force of 50 G at the first point, 1100 G at the second point, and 300 G at the third point. The second magnetic field (M2) generated from the second magnet (220) may be measured to have a magnetic force of 300 G at the fourth point, 1100 G at the fifth point, and 50 G at the sixth point. In comparison, referring to FIG. 4c, the first magnet (210) may have a first boundary surface (211) parallel to the folding axis (F), and the second magnet (220) may have a second boundary surface (221) inclined at a second angle (θ) with respect to the folding axis (F) toward the first magnet (210). In one embodiment, referring to FIG. 4c, the first magnetic field (M1) generated from the first magnet (210) may be measured to have a magnetic force of 100 G at the first point, 1200 G at the second point, and 100 G at the third point. The second magnetic field (M2) generated from the second magnet (220) may be measured to have a magnetic force of 300 G at the fourth point, 1100 G at the fifth point, and 50 G at the sixth point. The attractive force acting between the first magnet (210) and the second magnet (220) may be affected by the magnetic field strength at adjacent points. For example, referring to FIG. 4b, the first magnetic field (M1) of the first magnet (210) may be measured with a magnetic force of 300 G at a third point adjacent to the second magnet (220), and referring to FIG. 4c, the first magnetic field (M1) of the first magnet (210) may be measured with a magnetic force of 100 G at a third point adjacent to the second magnet (220).In this case, the embodiment of FIG. 4b, in which a relatively strong magnetic force is measured at a third point adjacent to the second magnet (220), may have a greater attractive force acting between the first magnet (210) and the second magnet (220) than the embodiment of FIG. 4c.

[0074] In summary, as shown in FIG. 4b, when the first boundary surface (211) of the first magnet (210) is inclined at a first angle (θ) with respect to the folding axis (F) so as to face the second magnet (220), the strength of the magnetic force of the first magnetic field (M1) measured at a third point adjacent to the second magnet (220) may increase compared to when the first boundary surface (211) is parallel to the folding axis (F) as shown in FIG. 4c. In addition, as shown in FIGS. 4b and 4c, when the second boundary surface (221) of the second magnet (220) is inclined at a second angle (θ) with respect to the folding axis (F) so as to face the first magnet (210), the magnetic force of the second magnetic field (M2) measured at a fourth point adjacent to the first magnet (210) may be greater than the magnetic force of the second magnetic field (M2) measured at a sixth point spaced apart from the first magnet (210). Accordingly, when the boundary surface (e.g., the first boundary surface (211), the second boundary surface (221)) of the first magnet (210) and / or the second magnet (220) is formed to be inclined with respect to the folding axis (F) so as to face the magnet located on the opposite side of the folding axis (F), the strength of the attractive force acting between the first magnet (210) and the second magnet (220) can increase.

[0075] The distances between the first point, the second point, and the third point with respect to the first magnet (210) illustrated in the drawing are merely examples and may be varied in various ways. In addition, the distances between the 24th point, the 5th point, and the 6th point with respect to the second magnet (220) are merely examples and may be varied in various ways.

[0076] In one embodiment, referring to FIG. 4c, when the second boundary surface (221) of the second magnet (220) is inclined at a second angle (θ) with respect to the folding axis (F) so as to face the first magnet (210), the strength of the attractive force acting between the first magnet (210) and the second magnet (220) may increase compared to the case where the first boundary surface (211) of the first magnet (210) and the second boundary surface (221) of the second magnet (220) are parallel to the folding axis (F). In one embodiment not shown in the drawing, when the first boundary surface (211) of the first magnet (210) and the second boundary surface (221) of the second magnet (220) are parallel to the folding axis (F), the first magnetic field (M1) of the first magnet (210) is 100 G at the first point, 1200 G at the second point, and 100 G at the third point. The second magnetic field (M2) of the second magnet (220) may be 100 G at the fourth point, 1200 G at the fifth point, and 100 G at the sixth point. The attractive force between the first magnet (210) and the second magnet (220) may be affected by the magnetic field strength at the adjacent points. For example, the attractive force between the first magnet (210) and the second magnet (220) may be affected by the magnetic field strength acting between the third point and the fourth point. Therefore, as shown in FIG. 4c, when the second boundary surface of the second magnet (220) is inclined toward the first magnet (210) with respect to the folding axis (F), the magnetic force of the second magnetic field (M2) measured at the fourth point is 300 G, so that the first boundary surface (211) of the first magnet (210) and the second boundary surface (221) of the second magnet (220) are parallel to the folding axis (F), as shown in FIG. 4c. The strength of the attractive force acting between the first magnet (210) and the second magnet (220) can increase.

[0077] In one embodiment, the graph illustrated in FIG. 4d is a graph showing the attractive force acting between the first magnet (210) and the second magnet (220) according to the first angle (θ) at which the first boundary surface (211) of the first magnet (210) illustrated in FIG. 4b is inclined with respect to the folding axis (F) and the second angle (θ) at which the second boundary surface (221) of the second magnet (220) is inclined with respect to the folding axis (F). In one embodiment, the first magnet (210) may have the first angle (θ) determined based on the amount of magnetic flux of the first magnetic field (M1) passing through the second magnet (220) and the angle at which the first boundary surface (211) forms with respect to the folding axis (F). Similarly, the second magnet (220) may have the second angle (θ) determined based on the amount of magnetic flux of the second magnetic field (M2) passing through the first magnet (210). The second angle (θ) can be determined. For example, the first magnet (210) can be determined at a first angle (θ) with respect to the folding axis (F) so that the density of the magnetic flux of the first magnetic field (M1) passing through the second magnet (220) increases. The second magnet (220) can be determined at a second angle (θ) with respect to the folding axis (F) so that the density of the magnetic flux of the second magnetic field (M2) passing through the first magnet (210) increases. In one embodiment, when the first angle (θ) of the first boundary surface (211) and the second angle (θ) of the second boundary surface (221) correspond to about 25 degrees, the attractive force acting between the first magnet (210) and the second magnet (220) can be a maximum attractive force of 0.87 N. However, the attractive force according to the angles shown in FIG. 4d is merely an example, and the first The angle that forms the maximum attractive force may vary depending on the shape of the magnet (210) and the second magnet (220) and the separation distance between the first magnet (210) and the second magnet (220). For example, the first angle (θ) and the second angle (θ) may be different angles.

[0078] FIG. 5A is a diagram illustrating a state in which a first magnet and a third magnet arranged in a first housing according to one embodiment of the present disclosure are arranged so as not to correspond with a second magnet arranged in a second housing with respect to the folding axis. FIGS. 5B, 5C, and 5D are diagrams explaining an attractive force acting between the first magnet and the third magnet and the second magnet according to a first angle at which the first boundary surface of the first magnet is inclined with respect to the folding axis, a second angle at which the second boundary surface of the second magnet is inclined with respect to the folding axis, and a third angle at which the third boundary surface of the third magnet is inclined with respect to the folding axis, as shown in FIG. 5A.

[0079] The description of FIGS. 5a to 5c to be described below is an embodiment in which a third magnet (230) is added to the embodiment described in FIGS. 4a to 4d described above.

[0080] According to one embodiment, as illustrated in FIG. 5A, the first housing (110) may include a first magnet (210) and a third magnet (230). The third magnet (230) may be positioned in a first direction (e.g., +X direction with respect to FIG. 5A) with respect to the first magnet (210) and may be spaced apart from the second magnet (220) in the first direction relative to the first magnet (210). Accordingly, a third axis (C3) having the highest magnetic flux density of a third magnetic field (M3) generated in the third magnet (230) and passing through the N pole and S pole of the third magnet (230) may not coincide with the second axis (C2) of the second magnet (220).

[0081] In one embodiment, the third magnet (230) may include a third boundary surface (231) that divides the N pole and the S pole. In one embodiment, as the third magnetic field (M3) generated in the third magnet (230) is directed toward the second magnet (220), the strength of the attractive force acting between the second magnet (220) and the third magnet (230) may increase. In one embodiment, the third magnet (230) may be formed so that the third boundary surface (231) is inclined at a third angle (θ) with respect to the folding axis (F) so as to face the second magnet (220) opposite to the folding axis (F). In this case, the third magnetic field (M3) generated in the third magnet (230) may face the second magnet (220). Accordingly, compared to the case where the third boundary surface (231) of the third magnet (230) is formed parallel to the folding axis (F), the amount of magnetic flux of the third magnetic field (M3) generated in the third magnet (230) passing through the second magnet (220) may increase. Accordingly, the amount of overlap between the second magnetic field (M2) of the second magnet (220) and the third magnetic field (M3) of the third magnet (230) may increase. Therefore, the second magnet (220) and the third The attractive force acting between the magnets (230) may increase.

[0082] In one embodiment, referring to FIG. 5A, the third magnet (230) may be positioned in the -X direction with respect to FIG. 5A relative to the second magnet (220) than the first magnet (210). In this case, the third boundary surface (231) of the third magnet (230) may be tilted more with respect to the folding axis (F) than the first boundary surface (211) of the first magnet (210) so as to face the second magnet (220). For example, referring to FIGS. 5B and 5D described below, the third angle (θ) formed by the third boundary surface (231) with the folding axis (F) may be greater than the first angle (θ) formed by the first boundary surface (211) with the folding axis (F).

[0083] In one embodiment, referring to FIG. 5A, the second magnet (220) may be influenced by a magnet that is closer to the first magnet (210) and the third magnet (230) than the third magnet (230) located on opposite sides of the folding axis (F). For example, the second angle (θ) formed by the second boundary surface (221) of the second magnet (220) with respect to the folding axis (F) may be determined by considering the density of the magnetic flux passing through the relatively close first magnet (210).

[0084] According to one embodiment, at least one of the first angle (θ) formed by the first boundary surface (211) with the folding axis (F), the second angle (θ) formed by the second boundary surface (221) with the folding axis (F), and the third angle (θ) formed by the third boundary surface (231) with the folding axis (F) may be formed at different angles. In one embodiment, the first magnet (210), the second magnet (220), and the third magnet (230) may be inclined with respect to the folding axis (F) so that the sum of the magnetic fields of the magnets positioned opposite to the folding axis (F) is maximized. For example, the first magnet (210) and the third magnet (230) may be inclined so that the density of the magnetic flux of the first magnetic field (M1) and the magnetic flux of the third magnetic field (M3) passing through the second magnet (220) increases. The first angle (θ) and the third angle (θ) can be determined. The second magnet (220) can be determined at the second angle (θ) so that the density of the magnetic flux of the second magnetic field (M2) passing through the first magnet (210) and the third magnet (230) increases.

[0085] According to one embodiment, the graphs shown in FIGS. 5b, 5c and 5d may be data obtained by experimenting with the attractive force acting between the first magnet (210), the second magnet (220) and / or the third magnet (230) in a state where only one boundary surface (211, 221, 231) among the first magnet (210), the second magnet (220) and the third magnet (230) is inclined with respect to the folding axis (F), and the other two boundary surfaces are parallel to the folding axis (F).

For example, the graph may be a graph showing the attractive force acting between the sum of the magnetic fields formed by the first magnet (210) and the third magnet (230) and the magnetic field acting on the second magnet (220). In one embodiment, referring to FIG. 5b, in a state where the second boundary surface (221) of the second magnet (220) and the third boundary surface (231) of the third magnet (230) are parallel to the folding axis (F), the first When the first angle (θ) formed by the first boundary surface (211) of the magnet (210) with the folding axis (F) is 20 degrees, the sum of the attractive forces acting between the first magnet (210), the third magnet (230), and the second magnet (220) can be maximized to 0.311 N.

[0087] In one embodiment, the graph illustrated in FIG. 5c may be a graph showing the attractive force acting between the first magnet (210), the second magnet (220), and the third magnet (230) according to the second angle (θ) that the second boundary surface (221) of the second magnet (220) forms with the folding axis (F) in a state where the first boundary surface (211) of the first magnet (210) and the third boundary surface (231) of the third magnet (230) are parallel to the folding axis (F). In one embodiment, referring to FIG. 5c, when the first boundary surface (211) of the first magnet (210) and the third boundary surface (231) of the third magnet (230) are parallel to the folding axis (F), the second angle (θ) that the second boundary surface (221) of the second magnet (220) forms with the folding axis (F) is 30 degrees, the attractive force acting between the first magnet (210) and the third magnet (230) The sum of the attractive forces acting between the magnet (230) and the second magnet (220) can be maximized to 0.325 N.

[0088] In one embodiment, the graph illustrated in FIG. 5d may be a graph showing the attractive force acting between the first magnet (210), the second magnet (220), and the third magnet (230) according to the third angle (θ) that the third boundary surface (231) of the third magnet (230) forms with the folding axis (F) in a state where the first boundary surface (211) of the first magnet (210) and the second boundary surface (221) of the second magnet (220) are parallel to the folding axis (F). In one embodiment, referring to FIG. 5d, when the first boundary surface (211) of the first magnet (210) and the second boundary surface (221) of the second magnet (220) are parallel to the folding axis (F), the third angle (θ) that the third boundary surface (231) of the third magnet (230) forms with the folding axis (F) is 70 degrees, the first magnet (210) and the third The sum of the attractive forces acting between the magnet (230) and the second magnet (220) can be maximized to 0.341 N.

[0090] FIG. 6A is a diagram illustrating a state in which first and third magnets arranged in a first housing and second and fourth magnets arranged in a second housing are not arranged relative to a folding axis according to one embodiment of the present disclosure. FIGS. 6B, 6C, 6D, and 6E are diagrams explaining an attractive force acting between the first and third magnets and the second and fourth magnets according to a first angle at which the first boundary surface of the first magnet is inclined with respect to the folding axis, a second angle at which the second boundary surface of the second magnet is inclined with respect to the folding axis, a third angle at which the third boundary surface of the third magnet is inclined with respect to the folding axis, and a fourth angle at which the fourth boundary surface of the fourth magnet is inclined with respect to the folding axis, as shown in FIG. 6A.

[0091] The description of FIGS. 6a to 6e to be described below is an embodiment in which a fourth magnet (240) is added to the embodiment described in FIGS. 5a to 5d described above.

[0092] According to one embodiment, as illustrated in FIG. 6A, the first housing (110) and the second housing (120) may include a plurality of magnets. In one embodiment, the first housing (110) may include a first magnet (210) and a third magnet (230). The second housing (120) may include a second magnet (220) and a fourth magnet (240). In one embodiment, the third magnet (230) may be positioned in a first direction (e.g., in the +X direction with respect to FIG. 6A) with respect to the first magnet (210) and may be spaced apart from the second magnet (220) in the first direction than the first magnet (210). In one embodiment, the fourth magnet (240) may be positioned in a second direction (e.g., in the -X direction with respect to FIG. 6A) with respect to the second magnet (220) and may be spaced apart from the first magnet (210) in the second direction than the second magnet (220). Therefore, the fourth axis (C4) having the highest magnetic flux density of the fourth magnetic field (M4) generated from the fourth magnet (240) and passing through the N pole and S pole of the fourth magnet (240) may not coincide with the first axis (C1) and the third axis (C3) of the second magnet (220).

[0093] In one embodiment, referring to FIG. 6A, the fourth magnet (240) may include a fourth boundary surface (241) that divides the N pole and the S pole. In one embodiment, as the amount of magnetic flux of the fourth magnetic field (M4) generated in the fourth magnet (240) that passes through the first magnet (210) and the third magnet (230) increases, the attractive force acting on the first magnet (210) and the third magnet (230) may increase. In one embodiment, the fourth magnet (240) may be formed so that the fourth boundary surface (241) is inclined at a fourth angle (θ) with respect to the folding axis (F) so as to face the first magnet (210) and the third magnet (230) with respect to the folding axis (F). In this case, the fourth magnetic field (M4) generated in the fourth magnet (240) may face the first magnet (210) and the third magnet (230). Accordingly, compared to the case where the fourth boundary surface (241) of the fourth magnet (240) is formed parallel to the folding axis (F), the amount of magnetic flux of the fourth magnetic field (M4) generated in the fourth magnet (240) passing through the first magnet (210) and the second magnet (220) may increase. Accordingly, the first magnetic field (M1) of the first magnet (210) and the third magnetic field (M3) of the third magnet (230) and The overlapping amount of the fourth magnetic field (M4) of the fourth magnet (240) may increase. Accordingly, the attractive force between the first magnet (210), the third magnet (230), and the fourth magnet (240) may increase.

[0094] In one embodiment, the fourth magnet (240) may be influenced by a magnet that is closer to the first magnet (210) and the third magnet (230) than the first magnet (210) and the third magnet (230) located on opposite sides with respect to the folding axis (F). For example, the fourth angle (θ) formed by the fourth boundary surface (241) of the fourth magnet (240) with respect to the folding axis (F) may be determined by considering the density of the magnetic flux passing through the relatively close first magnet (210).

[0095] In one embodiment, referring to FIG. 6A, the fourth magnet (240) may be positioned in the + X direction with respect to FIG. 6A relative to the first magnet (210) than the second magnet (220). In this case, the fourth boundary surface (241) of the fourth magnet (240) may be tilted more with respect to the folding axis (F) than the second boundary surface (221) of the second magnet (220) so as to face the first magnet (210). For example, referring to FIGS. 6C and 6E described below, the fourth angle (θ) formed by the fourth boundary surface (241) with the folding axis (F) may be greater than the second angle (θ) formed by the second boundary surface (221) with the folding axis (F).

[0096] According to one embodiment, at least one of the first angle (θ) formed by the first boundary surface (211) with the folding axis (F), the second angle (θ) formed by the second boundary surface (221) with the folding axis (F), the third angle (θ) formed by the third boundary surface (231) with the folding axis (F), and the angle formed by the fourth boundary surface (241) with the folding axis (F) may be formed at different angles. In one embodiment, the first magnet (210), the second magnet (220), the third magnet (230), and the fourth magnet (240) may be inclined with respect to the folding axis (F) such that the sum of the magnetic fields of the magnets positioned opposite to the folding axis (F) is maximized. For example, the first magnet (210) and the third magnet (230) The first angle (θ) and the second angle (θ) can be determined based on the amount of magnetic flux passing through the second magnet (220) and the fourth magnet (240) located opposite to the folding axis (F). For example, the first angle (θ) and the third angle (θ) can be determined so that the density of the magnetic flux of the first magnetic field (M1) and the magnetic flux of the third magnetic field (M3) passing through the second magnet (220) and the fourth magnet (240) increases. Similarly, the second angle (θ) and the fourth angle (θ) can be determined based on the amount of magnetic flux passing through the first magnet (210) and the third magnet (230) located opposite to the folding axis (F). For example, the second magnet (220) and the fourth magnet (240) can be determined so that the density of the magnetic flux of the first magnetic field (M1) and the magnetic flux of the third magnetic field (M3) passing through the second magnet (220) and the fourth magnet (240) increases. The second angle (θ) and the fourth angle (θ) can be determined so that the density of the magnetic flux of the second magnetic field (M2) and the magnetic flux of the fourth magnetic field (M4) passing through the third magnet (230) increases. Meanwhile, the first angle (θ) and the third angle (θ) can be determined based on the closer magnet among the second magnet (220) and the fourth magnet (240) located on opposite sides with respect to the folding axis (F) of the first magnet (210) and the third magnet (230).For example, the first angle (θ) that the first boundary surface (211) of the first magnet (210) forms with the folding axis (F) and the third angle (θ) that the third boundary surface (231) of the third magnet (230) forms with the folding axis (F) can be determined by considering the magnetic flux of the first magnetic field (M1) and the magnetic flux of the third magnetic field (M3) that pass through the second magnet (220). Similarly, the second angle (θ) and the fourth angle (θ) of the second magnet (220) and the fourth magnet (240) can be determined based on which of the first magnet (210) and the third magnet (230) is closer to the folding axis (F) than the other magnet. For example, the second angle (θ) that the second boundary surface (221) of the second magnet (220) forms with the folding axis (F) and the fourth boundary surface (241) of the fourth magnet (240) forms with the folding axis (F) The fourth angle (θ) formed with the folding axis (F) can be determined by considering the magnetic flux of the second magnetic field (M2) passing through the first magnet (210) and the magnetic flux of the fourth magnetic field (M4).

[0097] According to one embodiment, the graphs shown in FIGS. 6b, 6c, 6d and 6e may be data obtained by experimenting with the attractive force acting between the first magnet (210), the second magnet (220), the third magnet (230) and / or the fourth magnet (240) in a state where only one boundary surface (211, 221, 231, 241) among the first magnet (210), the second magnet (220), the third magnet (230) and the fourth magnet (240) is inclined with respect to the folding axis (F), and the remaining three boundary surfaces are parallel to the folding axis (F).

[0098] In one embodiment, the graph illustrated in FIG. 6b may be a graph showing the attractive force acting between the first magnet (210), the second magnet (220), the third magnet (230), and the fourth magnet according to the first angle (θ) that the first boundary surface (211) of the first magnet (210) forms with the folding axis (F) in a state where the second boundary surface (221) of the second magnet (220), the third boundary surface (231) of the third magnet (230), and the fourth boundary surface (241) of the fourth magnet (240) are parallel to the folding axis (F). For example, the graph may be a graph showing the attractive force due to the sum of the magnetic fields formed by the first magnet (210) and the third magnet (230) and the sum of the magnetic fields formed by the second magnet (220) and the fourth magnet (240). In one embodiment, referring to FIG. 6b, the second boundary surface (221) of the second magnet (220), the third boundary surface (231) of the third magnet (230), and the fourth boundary surface (241) of the fourth magnet (240) are parallel to the folding axis (F). When the third boundary surface (231) of the magnet (230) and the fourth boundary surface (241) of the fourth magnet (240) are parallel to the folding axis (F), and the first angle (θ) formed by the first boundary surface (211) of the first magnet (210) with the folding axis (F) is 30 degrees, the sum of the attractive forces acting between the first magnet (210) and the third magnet (230) and the second magnet (220) and the fourth magnet (240) can be maximized to 0.326 N.

[0099] In one embodiment, the graph illustrated in FIG. 6c may be a graph showing the attractive force acting between the first magnet (210), the second magnet (220), the third magnet (230), and the fourth magnet (240) according to the second angle (θ) that the second boundary surface (221) of the second magnet (220) forms with the folding axis (F) in a state where the first boundary surface (211) of the first magnet (210), the third boundary surface (231) of the third magnet (230), and the fourth boundary surface (241) of the fourth magnet (240) are parallel to the folding axis (F). In one embodiment, referring to FIG. 6c, in a state where the first boundary surface (211) of the first magnet (210), the third boundary surface (231) of the third magnet (230), and the fourth boundary surface (241) of the fourth magnet (240) are parallel to the folding axis (F), the second When the second angle (θ) formed by the second boundary surface (221) of the magnet (220) with the folding axis (F) is 30 degrees, the sum of the attractive forces acting between the first magnet (210) and the third magnet (230) and the second magnet (220) and the fourth magnet (240) can be maximized to 0.325 N.

[0100] In one embodiment, the graph illustrated in FIG. 6d may be a graph showing the attractive force acting between the first magnet (210), the second magnet (220), the third magnet (230), and the fourth magnet (240) according to the third angle (θ) that the third boundary surface (231) of the third magnet (230) forms with the folding axis (F) in a state where the first boundary surface (211) of the first magnet (210), the second boundary surface (221) of the second magnet (220), and the fourth boundary surface (241) of the fourth magnet (240) are parallel to the folding axis (F). In one embodiment, referring to FIG. 6d, in a state where the first boundary surface (211) of the first magnet (210), the second boundary surface (221) of the second magnet (220), and the fourth boundary surface (241) of the fourth magnet (240) are parallel to the folding axis (F), the third When the third angle (θ) formed by the third boundary surface (231) of the magnet (230) with the folding axis (F) is 75 degrees, the sum of the attractive forces acting between the first magnet (210) and the third magnet (230) and the second magnet (220) and the fourth magnet (240) can be maximized to 0.342 N.

[0101] In one embodiment, the graph illustrated in FIG. 6e may be a graph showing the attractive force acting between the first magnet (210), the second magnet (220), the third magnet (230), and the fourth magnet (240) according to the fourth angle (θ) that the fourth boundary surface (241) of the fourth magnet (240) forms with the folding axis (F) in a state where the first boundary surface (211) of the first magnet (210), the second boundary surface (221) of the second magnet (220), and the third boundary surface (231) of the third magnet (230) are parallel to the folding axis (F). In one embodiment, referring to FIG. 6e, in a state where the first boundary surface (211) of the first magnet (210), the second boundary surface (221) of the second magnet (220), and the third boundary surface (231) of the third magnet (230) are parallel to the folding axis (F), the fourth When the fourth angle (θ) formed by the fourth boundary surface (241) of the magnet (240) with the folding axis (F) is 75 degrees, the sum of the attractive forces acting between the first magnet (210) and the third magnet (230) and the second magnet (220) and the fourth magnet (240) can be maximized to 0.324 N.

[0102] In addition, the first boundary surface (211), the second boundary surface (221), the third boundary surface (231), and the fourth boundary surface (241) can be formed at various angles with respect to the folding axis (F) so that the attractive force acting between the first magnet (210), the second magnet (220), the third magnet (230), and the fourth magnet (240) is maximized.

[0103] In the above, the boundary surfaces (e.g., the first to fourth boundary surfaces (241)) of the first magnet (210), second magnet (220), third magnet (230), and fourth magnet (240) described are defined for convenience of explanation, and the N poles and S poles of the first to fourth magnets (240) may not be physically separated along the boundary surfaces.

[0104] In addition, although the boundary surfaces (211, 221, 231, 241) of the first magnet (210), the second magnet (220), the third magnet (230), and / or the fourth magnet (240) described above are described as being inclined at a certain angle with respect to the folding axis (F), the boundary surfaces (211, 221, 231, 241) may not be limited to being inclined with respect to the folding axis (F). In one embodiment, the first magnet (210) and / or the third magnet (230) disposed in the first housing (110) may be formed to have the boundary surfaces (211, 221, 231, 241) inclined with respect to a specific axis so that the attractive force between the second magnet (220) and / or the fourth magnet (240) disposed in the second housing (120) and the magnets located opposite to the folding axis is maximized.

[0105] FIG. 7a is a drawing showing various arrangement relationships of the first magnet and the second magnet according to one embodiment of the present disclosure. FIG. 7b is a front view of FIG. 7a. FIG. 7c is a right side view of FIG. 7a.

[0106] According to one embodiment, the relative positions of the first magnet (210) and the second magnet (220) can be variously modified. In one embodiment, referring to FIG. 7A, the first magnet (210) and the second magnet (220) can have different extension directions. For example, the first magnet (210) and the second magnet (220) can be respectively arranged in the first housing (110) and the second housing (120) so that the longitudinal extension directions are perpendicular to each other. In this case, the first boundary surface (211) of the first magnet (210) can be formed to face the second magnet (220), and the second boundary surface (221) of the second magnet (220) can be formed to face the first magnet (210) so as to increase the attractive force acting between the first magnet (210) and the second magnet (220).

[0107] In one embodiment, referring to FIGS. 7A to 7C, when the first magnet (210) and the second magnet (220) illustrated in FIG. 7A are viewed from various directions (e.g., +X direction or +Y direction), the first boundary surface (211) and the second boundary surface (221) may be formed to be inclined toward each other. In one embodiment, FIG. 7B is a front view of the first magnet and the second magnet of FIG. 7A when viewed in the +Y direction of FIG. 7A. In one embodiment, referring to FIG. 7B, the first magnet (210) may be formed to be inclined with respect to the X-axis of FIG. 7B such that the first boundary surface (211) faces the second magnet (220). The second magnet (220) may be formed to be inclined with respect to the X-axis of FIG. 7B such that the second boundary surface (221) faces the first magnet (210). In addition, Fig. 7c is a right side view of the first magnet and the second magnet of Fig. 7a when viewed in the + X direction of Fig. 7a. Referring to Fig. 7c, the first magnet (210) may be formed to be inclined with respect to the X-axis of Fig. 7b so that the first boundary surface (211) faces the second magnet (220). The second magnet (220) may be formed to be inclined with respect to the X-axis of Fig. 7b so that the second boundary surface (221) faces the first magnet (210). Accordingly, the first magnet (210) and the second magnet (220) may have an increased attractive force as the amount of overlap between the first magnetic field (M1) and the second magnetic field (M2) increases.

[0108] FIG. 8 is a drawing showing various arrangement relationships of a first magnet and a second magnet according to one embodiment of the present disclosure.

[0109] According to one embodiment, as illustrated in FIG. 8, the first magnet (210) may be formed to have a size included in the second magnet (220). In this case, at least one of the first magnet (210) and the second magnet (220) may be formed to have a first boundary surface (211) and a second boundary surface (221) facing a magnet (e.g., the first magnet (210) and / or the second magnet (220)) located opposite to the folding axis (F). In one embodiment, referring to FIG. 8, the first boundary surface (211) of the first magnet (210) may be formed in a direction parallel to the folding axis (F) and may have a size included in the second magnet (220). The second magnet (220) can be formed so that the second boundary surface (221) faces the first magnet (210) so that the magnetic flux density of the second magnetic field (M2) formed in the second magnet (220) increases in the overlapping portion with the first magnet (210). For example, the second boundary surface (221) of the second magnet (220) may be inclined at a second angle (θ) with respect to the folding axis (F) and may face the first magnet (210). In one embodiment not shown in the drawing, the first magnet (210) may be inclined at a first angle (θ) with respect to the folding axis (F) so that the first boundary surface (211) faces the second boundary surface (221) which is inclined at a first angle (θ) with respect to the folding axis (F). In one embodiment, referring to FIG. 4c described above, when the first boundary surface (211) is inclined at a first angle (θ) with respect to the folding axis (F) so that the first boundary surface (211) faces the second magnet (220) rather than being parallel to the folding axis (F), the intensity of the magnetic field of the first magnet (210) may be measured higher at a third point adjacent to the second magnet (220). Therefore, according to one embodiment of the present disclosure, the first At least one of the magnets (210) and the second magnets (220) may be formed such that the first boundary surface (211) and the second boundary surface (221) are inclined with respect to the folding axis (F) so as to face the magnet located opposite to the folding axis (F). Accordingly, the first magnet (210) and the second magnet (220) may have an increased amount of overlap between the first magnetic field (M1) and the second magnetic field (M2), thereby increasing the attractive force.

[0110] FIG. 9a and FIG. 9b are drawings illustrating a state in which a first magnet and a second magnet are arranged in a Halbach arrangement according to one embodiment of the present disclosure.

[0111] In one embodiment, referring to FIGS. 9A and 9B , the first magnet (310) disposed in the first housing (110) and the second magnet (320) disposed in the second housing (120) may include a plurality of magnets arranged so that one surface facing the display (130) exhibits multiple magnetizations. In one embodiment, referring to FIGS. 9A and 9B , the first magnet (310) may include a plurality of magnets arranged so that the N and S poles alternate on one surface facing the display (130). For example, the first magnet (310) may include a plurality of magnets arranged in a Halbach array. Similarly, the second magnet (320) may include a plurality of magnets arranged so that the N and S poles alternate on one surface facing the display (130). For example, the second magnet (320) may include a plurality of magnets arranged in a Halbach array. For convenience of explanation, the following description assumes that the first magnet (310) and the second magnet (320) are magnets having a Halbach arrangement.

[0112] According to one embodiment, as illustrated in FIGS. 9A and 9B, the first magnet (310) may be arranged in the first housing (110) such that the plurality of magnets face the display (130). The second magnet (320) may be arranged such that the plurality of magnets face the display (130) such that the first magnet (310) and the second magnet (320) exert an attractive force when the electronic device (100) is folded. According to one embodiment, the plurality of magnets included in the first magnet (310) and the second magnet (320) may be formed to have the same size or different sizes.

[0113] According to one embodiment, as illustrated in FIGS. 9A and 9B, a plurality of magnets included in the first magnet (310) and a plurality of magnets included in the second magnet (320) may form an interface that divides the N pole and the S pole so that the N pole faces the magnets facing each other with respect to the folding axis (F). For example, the plurality of magnets included in the first magnet (310) may be formed to be inclined at a certain angle with respect to the Y-axis with respect to FIG. 9A so as to face the plurality of magnets included in the second magnet (320) corresponding to the folding axis (F). Similarly, the plurality of magnets included in the second magnet (320) may be formed to be inclined at a certain angle with respect to the Y-axis with respect to FIG. 9A so as to face the plurality of magnets included in the first magnet (310) corresponding to the folding axis (F).
