According to an embodiment, the electronic device 101 may communicate with the electronic device 104 via the server 108. According to an embodiment, the electronic device 101 may include a processor 120, a memory 130, an input module 150, a sound output module 155, a display module 160, an audio module 170, a sensor module 176, an interface 177, a connection terminal 178, a haptic module 179, a camera module 180, a power management module 188, a battery 189, a communication module 190, a user identification module (SIM) 196, or an antenna module 197. In an embodiment, at least one of the above components (e.g., the connection terminal 178) may be omitted from the electronic device 101, or one or more other components may be added to the electronic device 101.

[0282] According to an embodiment, when the electronic device changes from an unfolded state to a folded state, at least some of the magnetic members 363a and 363b are configured not to overlap with the first facing portion in the length direction of the electronic device, so that the coupling force generated by the magnetic force formed by the magnetic members 363a and 363b and the first facing portion can gradually decrease.

[0283] Fig.11 is a view schematically illustrating a joining force generated by a magnetic force according to an embodiment of the present disclosure.

[0284] Fig.11 The embodiments can be used with Figure 1 to Figure 1 0 embodiment or Figures 12a to 22 Combination of embodiments.

[0285] For ease of description, Fig.11 The first group B1 is Figures 6a to 6d The description is made taking any one of the 2-1st magnetic members 373a and the second facing portion 354b facing the 2-1st magnetic member 373a as an example, but the description is equally applicable to and understood as other magnetic members and facing members.

[0286] Check Fig.11 In the second group B2, a region (hereinafter, "first region") is shown: when the first 2-1 rotating cam member (for example, Figures 6a to 6d The 2-1st rotating cam member 370a) is relative to the second hinge bracket (eg, Figures 6a to 6d When the second hinge bracket 350b of the electronic device rotates, for each rotation angle, in the length direction of the electronic device ( Figure 7b In the Y-axis direction), the region is aligned with the 2-1 magnetic member (for example, Figures 6a to 6d The second magnetic member 373a and the second facing portion (eg, Figures 6a to 6d The protruding portion of the second facing portion 354b) (eg, Figure 7b The protruding portion 354b-1) overlaps.

[0287] For example, the first area when the rotation angle is 5 degrees may be smaller than when the rotation angle is 0 degrees.

[0288] When the rotation angle is 0 degrees, the protruding portion can completely cover the second magnetic member in the length direction of the electronic device, thereby maximizing the first area. At this time, the coupling force formed by the second magnetic member and the second facing portion through magnetic force can be maximized.

[0289] When the rotation angle is 5 degrees, the concave portion of the second facing portion (eg, Figure 7b At least some of the recessed portions 354b-2) overlap with at least a portion of the second magnetic member in the length direction of the electronic device, so it can be determined that the size of the first area is reduced compared to when the rotation angle is 0 degrees.

[0290] When the rotation angle gradually increases (for example, when the rotation angle increases from 0 degrees to 30 degrees), the number or size of the first area may change, where the protruding portion of the second facing portion and the second magnetic member overlap each other in the length direction of the electronic device.

For example, the protruding portion 354a-1 may be defined and referred to as an embossed shape, and the concave portion 354a-2 may be defined and referred to as an inverse embossed shape. According to an embodiment, a plurality of protruding portions 354a-1 and a plurality of concave portions 354a-2 may be alternately disposed.

[0298] According to an embodiment, in the 1-1st rotating cam member 360a, as the area of ​​overlap between the protruding portion 354a-1 of the first facing portion 354a and the 1-1st magnetic member 363a in the length direction of the electronic device increases, the engagement force generated by magnetism can be increased. For example, since the protruding portion 354a-1 is disposed closer to the 1-1st magnetic member 363a than the recessed portion 354a-2, the magnetic engagement force formed by the tiny area of ​​the protruding portion 354a-1 and the tiny area of ​​the 1-1st magnetic member 363a can be greater than the magnetic engagement force formed by the tiny area of ​​the recessed portion 354a-2 and the tiny area of ​​the 1-1st magnetic member 363a.

[0302] In addition, when the rotation angle is 30 degrees, any one of the 1-1 magnetic members 363a does not overlap with the first facing portion 354a in the length direction of the electronic device, so it can be identified that the bonding force formed by magnetism when the rotation angle is 30 degrees is lower than the bonding force formed by magnetism when the rotation angle is 0 degrees.

[0304] In addition, when the rotation angle is 60 degrees, two of the 1-1 magnetic members 363a do not overlap with the first facing portion 354a in the length direction of the electronic device, so it can be determined that the joining force formed by magnetism when the rotation angle is 60 degrees is lower than the joining force formed by magnetism when the rotation angle is 30 degrees.

[0305] When the 1-1 rotating cam member 360a changes from 60 degrees to 90 degrees relative to the first hinge bracket 350a, the area in which the 1-1 magnetic member 363a and the recessed portion 354a-2 overlap with each other in the length direction of the electronic device increases and then decreases, so that the magnetic coupling force formed by the 1-1 magnetic member 363a and the first facing portion 354a can decrease and then increase.

[0306] In addition, when the rotation angle is 90 degrees, three of the 1-1 magnetic members 363a do not overlap with the first facing portion 354a in the length direction of the electronic device, so it can be determined that the joining force formed by magnetism when the rotation angle is 90 degrees is lower than the joining force formed by magnetism when the rotation angle is 60 degrees.
