The foldable housing 500 includes a first housing structure 510, a second housing structure 520 including a sensor area 524, a first back cover 580, and a second back cover 590. The foldable housing 500 is not limited to the form and coupling illustrated in
The first housing structure 510 and the second housing structure 520 may be disposed on opposite sides of a folding axis (axis A) and may have shapes that are entirely symmetric to each other with respect to the folding axis A. The angle or distance between the first housing structure 510 and the second housing structure 520 may vary depending on whether the electronic device 10 is in a flat state, a folded state, or an intermediate state. The second housing structure 520 additionally includes a sensor area 524 in which various sensors are disposed. The first housing structure 510 and the second housing structure 520 have a mutually symmetrical shape in the other areas.
The first housing structure 510 and the second housing structure 520 may form a recess in which the display 110 is received. Due to the sensor area 524, the recess may have two or more different widths in a direction perpendicular to the folding axis A.
For example, the recess may have (1) a first width w1 between a first portion 510a of the first housing structure 510 that is parallel to the folding axis A and a first portion 520a of the second housing structure 520 that is formed on the periphery of the sensor area 524 and (2) a second width w2 between a second portion 510b of the first housing structure 510 and a second portion 520b of the second housing structure 520 that does not correspond to the sensor area 524 and that is parallel to the folding axis A. The second width w2 may be formed to be greater than the first width w1. That is, the first portion 510a of the first housing structure 510 and the first portion 520a of the second housing structure 520 that have mutually asymmetrical shapes may form the first width w1 of the recess, and the second portion 510b of the first housing structure 510 and the second portion 520b of the second housing structure 520 that have mutually symmetrical shapes may form the second width w2 of the recess.
The first portion 520a and the second portion 520b of the second housing structure 520 may have different distances from the folding axis A. The widths of the recess are not limited to the illustrated example. For example, the recess may have a plurality of widths depending on the form of the sensor area 524 or the asymmetrical portions of the first housing structure 510 and the second housing structure 520.
At least part of the first housing structure 510 and at least part of the second housing structure 520 may be formed of a metallic material or a non-metallic material that has a stiffness selected to support the display 110.
The sensor area 524 may have a predetermined area formed adjacent to one corner of the second housing structure 520. However, the arrangement, shape, and size of the sensor area 524 are not limited to the illustrated example. For example, the sensor area 524 may be provided in another corner of the second housing structure 520 or in any area between an upper corner and a lower corner of the second housing structure 520.
Parts embedded in the electronic device 10 to perform various functions may be exposed on the front surface of the electronic device 10 though the sensor area 524 or through one or more openings formed in the sensor area 524. The parts may include various types of sensors, such as a front camera, a receiver, and/or a proximity sensor.
The first back cover 580 may be disposed on one side of the folding axis A on the rear surface of the electronic device 10. The first back cover 580 may have a substantially rectangular periphery, and the periphery may be surrounded by the first housing structure 510. Similarly, the second back cover 590 may be disposed on an opposite side of the folding axis A on the rear surface of the electronic device 10 and may have a periphery surrounded by the second housing structure 520.
The first back cover 580 and the second back cover 590 may have substantially symmetrical shapes with respect to the folding axis (the axis A). However, the first back cover 580 and the second back cover 590 do not necessarily have to have mutually symmetrical shapes. The electronic device 10 may include the first back cover 580 and the second back cover 590 that have various shapes. Alternatively, the first back cover 580 may be integrated with the first housing structure 510, and the second back cover 590 may be integrated with the second housing structure 520.
The first back cover 580, the second back cover 590, the first housing structure 510, and the second housing structure 520 may form a space in which various parts (e.g., a printed circuit board (PCB) or a battery) of the electronic device 10 are disposed. One or more parts may be disposed, or visually exposed, on the rear surface of the electronic device 10. At least part of a sub-display 190 may be visually exposed through a first rear area 582 of the first back cover 580. Alternatively, one or more parts or sensors may be visually exposed through a second rear area 592 of the second back cover 590. The sensors may include a proximity sensor and/or a rear camera.

The areas of the display 110 are illustrative, and the display 110 may be divided into a plurality of areas (e.g., four or more areas, or two areas) depending on the structure or function of the display 110. For example, in
The first area 111 and the second area 112 may have shapes that are entirely symmetric to each other with respect to the folding area 113. The second area 112 may include a notch that is cut depending on the presence of the sensor area 524. However, in the other areas, the second area 112 may be symmetrical to the first area 101. That is, the first area 111 and the second area 112 may include symmetrical portions and asymmetrical portions.

At least part of the folding area 113 may be formed to be a curved surface having a predetermined curvature, and the curvature may be smaller than that in the folded state.
