FIG.1is a front perspective view of a foldable electronic device1in an unfolded (or flat or unfolding) state according to various embodiments.FIG.2is a rear perspective view of a foldable electronic device1in an unfolded state according to various embodiments.FIG.3is a perspective view of a foldable electronic device1in a folded (or folding) state according to various embodiments.

With reference toFIGS.1,2, and3, in an embodiment, the electronic device (or foldable electronic device)1may include a foldable housing10. The foldable housing10may have a front surface10A of the electronic device1and a rear surface10B of the electronic device1positioned opposite to the front surface10A. The foldable housing10may include a first side surface10C and a second side surface10D of the electronic device1that at least partially surround a space between the front surface10A and the rear surface10B. The front surface10A may include a first cover area {circle around (1)}, a second cover area {circle around (2)}, and a folding cover area F between the first cover area {circle around (1)} and the second cover area {circle around (2)}. In the unfolded state of the foldable housing10, the front surface10A may be substantially planar, and the first cover area {circle around (1)}, the second cover area {circle around (2)}, and the folding cover area F may face in substantially the same direction. The rear surface10B may include a third cover area {circle around (3)} and a fourth cover area {circle around (4)}. The third cover area {circle around (3)} is positioned opposite to the first cover area {circle around (1)} of the front surface10A and may face in the opposite direction to the first cover area {circle around (1)}. The fourth cover area {circle around (4)} is positioned opposite to the second cover area {circle around (2)} of the front surface10A and may face in the opposite direction to the second cover area {circle around (2)}. In an embodiment, the foldable housing10may be implemented as an in-folding structure in which the front surface10A is foldable inward. For example, in the unfolded state of the foldable housing10(seeFIG.1), the folding cover area F is flat, and the first cover area {circle around (1)} and the second cover area {circle around (2)} may form an angle of about 180 degrees. In the folded state of the foldable housing10(seeFIG.3), the folding cover area F is curved, and the first cover area {circle around (1)} and the second cover area {circle around (2)} may form an angle different from about 180 degrees. The folded state may include a fully folded state or an intermediate state. The fully folded state (seeFIG.3) is a state in which the first cover area {circle around (1)} and the second cover area {circle around (2)} of the front surface10A are maximally folded so that they are no longer close. For example, the first cover area {circle around (1)} and the second cover area {circle around (2)} may form an angle of about 0 degrees to about 10 degrees. In the fully folded state, the front surface10A may not be substantially exposed to the outside. The intermediate state may refer to a state between the unfolded state and the fully folded state. The folding cover area F of the front surface10A may be more bent in the fully folded state than in the intermediate state.

In various embodiments, a flexible material may be disposed on a rear surface of the hinge housing cover region721that may face the hinge cover130. In various embodiments, a lubricating material may be adhered to or coated on the rear surface of the hinge housing cover region721so as to reduce friction with the hinge cover130.

According to an embodiment, the strap7may include a third portion73extending from the second portion72. The third portion73may be provided so as not to pass through the opening of the opening structure65included in the second cover6. In order not to pass through the opening structure65, the third portion73may have a shape causing interference with an area (e.g., the first structure part651, the second structure part652, or the third structure part653) surrounding the opening of the opening structure65. The third portion73may make it difficult for the second cover6to disengage from the second portion72of the strap7.

According to an embodiment, in the fully folded state (seeFIG.6or7) of the electronic device1, the third portion73may come in contact with the opening structure65, and a tension may be applied to the second portion72so that the second portion72does not lift from the fourth surface61B of the second cover6. For example, in the fully folded state of the electronic device1, the second portion72of the strap7may be in contact with the hinge cover130and the fourth surface61B of the second cover6. In various embodiments, the fourth side61B of the second cover6may have a recess in which the second portion72of the strap7can be located in the folded state of the electronic device1.

According to an embodiment, the second portion72of the strap7may be in a movable state relative to the opening structure65of the second cover6in the unfolded state of the electronic device1shown inFIGS.4and5. In another example, the second portion72of the strap7may be in a movable state relative to the opening structure65of the second cover6when the electronic device1is in the intermediate state (seeFIG.9). With reference toFIGS.7and8, of the second portion72of the strap7, a part located between the first portion71and the opening structure65may be adjusted in length to be used for stably carrying the electronic device1combined with the cover4with the hand H. In an embodiment, the second portion72of the strap7may be in a state where it is difficult to move relative to the opening structure65of the second cover6in the fully folded state of the electronic device1shown inFIGS.6and7. For example, in the fully folded state of the electronic device1, the second portion72of the strap7may be in contact with the hinge cover130and the fourth surface61B of the second cover6. In various embodiments, the second portion72of the strap7may have a movable length even in the fully folded state of the electronic device1.

According to an embodiment, a connecting member (or connecting portion or connecting support)8may be connected to the third portion73of the strap7. The connecting member8may be in the form of a ring made of a metallic material or a non-metallic material. The third portion73of the strap7may have a loop shape passing through the connecting member8and being bent. The third portion73may have a loop shape, for example, by being provided in a manner of attaching one end of the strap7to certain other point of the strap. Such a structure of the third portion73in which one end of the strap7overlaps with and is attached to other point of the strap may make it difficult for the third portion73to pass through the opening structure65. The connecting member8may be used to connect an external member (or an external device or an external body) such as an accessory. For example, as shown inFIG.9, another strap9for placement on a user's body, such as a hand strap (e.g., an accessory for mounting on a user's hand) or a neck strap (e.g., an accessory for mounting on a user's neck), may be connected to the connecting member8of the cover4. Various other accessories may be connected to the connecting member8of the cover4.

According to various embodiments, the third portion73that is difficult to pass through the opening structure65is not limited to the illustrated example, and it may be provided in various other shapes that may cause interference with the opening structure65. For example, the third portion73may be implemented as a separate member disposed on or combined with the second portion72and connectable to the connecting member8.

According to various embodiments, the third portion73may be implemented to be insertable at least partially into the opening structure65when the second portion72of the strap7is positioned so as not to lift from the fourth surface61B of the second cover6in the fully folded state (seeFIG.6or7) of the electronic device1, or when it is difficult for the user to lift any more a part of the second portion72of the strap7located between the first portion71and the opening structure65.

When viewed from above the first surface51A (e.g., in the negative z-axis direction), the first sheet1010may be disposed so as not to overlap with the first portion71of the strap7. The first sheet1010may increase a contact or friction force with the first housing110(seeFIG.1or2) of the electronic device1, thereby contributing to stably positioning the first housing110on the first cover5. In various embodiments, the first sheet1010may be modified to be disposed on the first portion71of the strap7or to be expanded to the first portion71of the strap7. In various embodiments, the first sheet1010may be modified to be disposed on the first side52of the first cover5or to be expanded to the first side52.

According to an embodiment, the second sheet1020may be disposed on the third surface61A of the second bottom61included in the second cover6. The third surface61A may face the fourth cover area {circle around (4)} (seeFIG.2) of the electronic device1. The second sheet1020may include, for example, a flexible material such as rubber. The second sheet1020may increase a contact or friction force with the second housing120(seeFIG.1or2) of the electronic device1, thereby contributing to stably positioning the second housing120on the second cover6. In various embodiments, the second sheet1020may be modified to be disposed on, or expanded to, the second side62of the second cover6.

According to various embodiments, the first sheet1010or the second sheet1020, as an adhesive sheet, may be an adhesive capable of being adhered to the cover4only by applying a small amount of pressure at room temperature for a short time without using curing conditions such as water, solvent (e.g., curing agent), heat, or light. The adhesive sheet may give temporary adhesion capable of being detached from and attached to the cover4and have a non-curing feature.
