The second bracket 42 may have a space provided by the combination of the fourth portion 404, the first support wall 4231, and the second support wall 4232. A portion included the first portion 401 of the first bracket 41 may be positioned in the space. Since a portion included in the first portion 401 of the first bracket 41 is positioned between the first support wall 4231 and the second support wall 4232 of the second bracket 42, the range of mutual sliding between the first bracket 41 and the second bracket 42 may be constrained.

According to an embodiment, the first elastic element 44 and the second elastic element 45 may be positioned between the first bracket 41 and the second bracket 42. The first elastic element 44 and the second elastic element 45 may provide elasticity for the linear motion (or translational motion) of the second bracket 42 relative to the first bracket 41.

According to an embodiment, the first elastic element 44 and the second elastic element 45 may be disposed at positions symmetrical to each other with respect to the centerline B of the hinge module 4.

According to an embodiment, depending on the relative position between the first bracket 41 and the second bracket 42, the elasticity provided by the first elastic element 44 and the elasticity provided by the second elastic element 45 may be substantially identical. The first elastic element 44 and the second elastic element 45 may be substantially the same type of elastic element.

According to an embodiment, based on the first elastic element 44 and the second elastic element 45, which provide elasticity between the first bracket 41 and the second bracket 42, one or more components of the hinge module 4 may be implemented to enable stable and balanced linear motion (or translational motion) of the second housing 12 connected to the second bracket 42 relative to the first housing 11 connected to the first bracket 41.

According to an embodiment, the first bracket 41 may include a first elastic element support 411 and a second elastic element support 412. The first elastic element support 411 and the second elastic element support 412 may extend from, or be connected to, the first portion 401. The first elastic element support 411 and the second elastic element support 412 may be positioned between the first support wall 4231 and the second support wall 4232 of the second bracket 42. The first elastic element support 411 may be provided in a form protruding from the first portion 401 to correspond to the first elastic element 44 and the first support wall 4231 of the second bracket 42. The second elastic element support 412 may be provided in a form protruding from the first portion 401 to correspond to the second elastic element 45 and the first support wall 4231 of the second bracket 42. The first elastic element 44 may be disposed between the first elastic element support 411 of the first bracket 41 and the first support wall 4231 of the second bracket 42. The second elastic element 45 may be disposed between the second elastic element support 412 of the first bracket 41 and the first support wall 4231 of the second bracket 42.

According to various embodiments, the first elastic element support 411 and the second elastic element support 412 may be interpreted as a portion of the first portion 401.

According to an embodiment, the folded state of the foldable electronic device 1 (or the foldable housing 10) may include a first folded state and a second folded state, depending on the relative position between the first bracket 41 and the second bracket 42.

According to an embodiment, the first folded state may correspond to a state in which the elastic element supports (e.g., the first elastic element support 411 and the second elastic element support 412) of the first bracket 41 and the first support wall 4231 of the second bracket 42 are spaced apart from each other by a substantially maximum first distance in the direction of the centerline B of the hinge module 4 (e.g., the y-axis direction). The second folded state may correspond to a state in which the elastic element supports (e.g., the first elastic element support 411 and the second elastic element support 412) of the first bracket 41 and the first support wall 4231 of the second bracket 42 are spaced apart from each other by a minimum or small second distance, or a second distance smaller than the first distance, in the direction of the centerline B of the hinge module 4 (e.g., the y-axis direction).

According to an embodiment, when an external force is applied to linearly move the second housing 12 in a first direction {circle around (1)} (e.g., the +y-axis direction) relative to the first housing 11, the second bracket 42 connected to the second housing 12 may linearly move in the first direction {circle around (1)} relative to the first bracket 41 connected to the first housing 11, and the foldable electronic device 1 may be switched from the first folded state to the second folded state.

According to an embodiment, when the second bracket 42 linearly moves in a second direction {circle around (2)} (e.g., the-y-axis direction) opposite to the first direction {circle around (1)}, relative to the first bracket 41 due to the elasticity of the first elastic element 44 and the elasticity of the second elastic element 45, the second housing 12 connected to the second bracket 42 may linearly move in the second direction {circle around (2)} relative to the first housing 11 connected to the first bracket 41, and the foldable electronic device 1 may be switched from the second folded state to the first folded state.

According to an embodiment, the elasticity of the first elastic element 44 and the elasticity of the second elastic element 45 may provide a retaining force that maintains the first housing 11 and the second housing 12 in a relative positional relationship corresponding to the first folded state.

According to an embodiment, in the first folded state, the distance between the first elastic element support 411 of the first bracket 41 and the first support wall 4231 of the second bracket 42 may be greater than that in the second folded state, and the first elastic element 44 may be less compressed or substantially uncompressed compared to its state in the second folded state. In the first folded state, the distance between the second elastic element support 412 of the first bracket 41 and the first support wall 4231 of the second bracket 42 may be greater than that in the second folded state, and the second elastic element 45 may be less compressed or substantially uncompressed compared to its state in the second folded state. In the second folded state, the distance between the first elastic element support 411 of the first bracket 41 and the first support wall 4231 of the second bracket 42 may be smaller than that in the first folded state, and the first elastic element 44 may be in a more compressed state compared to its state in the first folded state. In the second folded state, the distance between the second elastic element support 412 of the first bracket 41 and the first support wall 4231 of the second bracket 42 may be smaller than that in the first folded state, and the second elastic element 45 may be in a more compressed state compared to its state in the first folded state.

According to an embodiment, the first elastic element 44 may be a first coil compression spring, and the second elastic element 45 may be a second coil compression spring. The second bracket 42 may include a first protrusion 424 extending in the first direction {circle around (1)} from the first support wall 4231. The second bracket 42 may include a second protrusion 425 extending in the first direction {circle around (1)} from the first support wall 4231. The first protrusion 424 may be inserted into the central space of the first coil compression spring. The second protrusion 425 may be inserted into the central space of the second coil compression spring. The first protrusion 424 may reduce or prevent the first coil compression spring from detaching from the space between the first elastic element support 411 of the first bracket 41 and the first support wall 4231 of the second bracket 42. The second protrusion 425 may reduce or prevent the second coil compression spring from detaching from the space between the second elastic element support 412 of the first bracket 41 and the first support wall 4231 of the second bracket 42.

According to various embodiments, the first elastic element 44 or the second elastic element 45 is not limited to coil compression springs, and may be implemented in various other types of elastic elements (e.g., a flexible member like rubber, or various other types of springs). Depending on the types of the elastic elements, the first protrusion 424 and the second protrusion 425 may be omitted.

According to various embodiments, an integrated elastic element (e.g., a flexible member such as rubber or various other types of springs) that replaces the first elastic element 44 and the second elastic element 45 may be implemented. Depending on the types of the elastic elements, the first protrusion 424 and the second protrusion 425 may be omitted.

According to an embodiment, when the foldable electronic device 1 is switched from the second folded state (see FIG. 30) to the first folded state (see FIG. 29), the relative position of the seventh magnetic element 2910 with respect to the eighth magnetic element 2920 and the ninth magnetic element 2930 may change such that the attractive force between the seventh magnetic element 2910 and the eighth magnetic element 2920 is provided to be relatively stronger than the repulsive force between the seventh magnetic element 2910 and the ninth magnetic element 2930 due to the relative position between the first housing 11 and the second housing 12 corresponding to the first folded state.

According to an embodiment, in the first folded state of the foldable electronic device 1 (see FIG. 29), the seventh magnetic element 2910 and the eighth magnetic element 2920 may be aligned due to the relative position between the first housing 11 and the second housing 12 corresponding to the first folded state. The attractive force between the aligned seventh and eighth magnetic elements 2910 and 2920 may reduce or prevent separation between the first housing 11 and the second housing 12 in the first folded state of the foldable electronic device 1. In the first folded state of the foldable electronic device 1, the repulsive force between the seventh magnetic element 2910 and the ninth magnetic element 2930 may be too small to substantially cause separation between the first housing 11 and the second housing 12, compared to the attractive force between the seventh magnetic element 2910 and the eighth magnetic element 2920.

According to an embodiment, when the foldable electronic device 1 is switched from the first folded state (see FIG. 29) to the second folded state (see FIG. 30), the relative position of the seventh magnetic element 2910 with respect to the eighth magnetic element 2920 and the ninth magnetic element 2930 may change such that the repulsive force between the seventh magnetic element 2910 and the ninth magnetic element 2930 is provided to be relatively stronger than the attractive force between the seventh magnetic element 2910 and the eighth magnetic element 2920 due to the relative position between the first housing 11 and the second housing 12 corresponding to the second folded state.

According to an embodiment, when the foldable electronic device 1 is switched from the first folded state (see FIG. 29) to the second folded state (see FIG. 30), the repulsive force between the seventh magnetic element 2910 and the ninth magnetic element 2930 may cause separation between the first housing 11 and the second housing 12. The second folded state may be or include a state in which separation between the first housing 11 and the second housing 12 is caused by the repulsive force between the seventh magnetic element 2910 and the ninth magnetic element 2930. When the foldable electronic device 1 is switched from the first folded state to the second folded state, the attractive force between the seventh magnetic element 2910 and the eighth magnetic element 2920 may be too small to substantially suppress separation between the first housing 11 and the second housing 12, compared to the repulsive force between the seventh magnetic element 2910 and the ninth magnetic element 2930.

According to an embodiment, the second folded state, in which separation is provided between the first housing 11 and the second housing 12, may be interpreted as an intermediate state between the first folded state and the unfolded state, facilitating the switching of the foldable electronic device 1 to the unfolded state compared to the first folded state.
