Description:
CROSS-REFERENCE TO RELATED APPLICATION(S) 
     This application is a Continuation of and based on and claims priority under 35 U.S.C. § 120 to PCT International Application No. PCT/KR2022/000290, which was filed on Jan. 7, 2022, and claims priority to Korean Patent Application No. 10-2021-0011415, filed on Jan. 27, 2021, in the Korean Intellectual Property Office, the disclosures of which are incorporated by reference herein their entirety. 
    
    
     TECHNICAL FIELD 
     Certain embodiments of the disclosure relate to an electronic device including at least one sealing member, and more particularly, to a foldable electronic device having a seal protecting against intrusion by foreign contaminants. 
     BACKGROUND 
     The use of foldable electronic devices such as foldable smartphones and tablet-style personal computers (PCs) is increasing. 
     A foldable electronic device may have a variable physical configuration, in which a first housing and a second housing may be folded or unfolded around a hinge module. 
     For example, a foldable electronic device may be configured to be in an in-folding and/or an out-folding configuration, as set via rotations of the first housing and the second housing about the hinge module. 
     A foldable electronic device may include a flexible display disposed at least partially across a first housing, a hinge module, and a second housing. 
     In the foldable electronic device, when the first housing and the second housing are folded using the hinge module, the flexible display may be folded, and when the first housing and the second housing are unfolded, the flexible display may be unfolded. 
     A plurality of electronic components may be disposed on a printed circuit board disposed in an internal space of the foldable electronic device. In the foldable electronic device, the operation of the electronic components may be affected by the foldable configuration. Furthermore, allowing foldability often creates gaps and seams in the external housing, and accordingly, the foldable device is at risk to damage and internal contamination incident from invasive moisture and/or foreign substances introduced into the interior of the device from an external environment. 
     Accordingly the foldable electronic device may be particularly weak with regards to waterproofing and/or dustproofing in specific portions of the first housing and the second housing near to the hinge module, where such gaps and openings often occur. 
     SUMMARY 
     Certain embodiments of the disclosure may provide a foldable electronic device including waterproofing and/or dustproofing using at least one sealing member irrespective of the foldable configuration. 
     According to certain embodiments of the disclosure, an electronic device includes a hinge module, a first housing to which a first side of the hinge module and at least a portion of a first support plate are coupled, the first housing including a first side surface, a second side surface, and a third side surface, a second housing to which a second side of the hinge module and at least a portion of the second support plate are coupled, the second housing including a fourth side surface, a fifth side surface, and a sixth side surface, wherein the second housing is foldable and unfoldable with the first housing about a folding axis defined by the hinge module, a flexible display spanning at least a portion of the first housing and the second housing, wherein the flexible display is foldable and unfoldable along with folding and unfolding of the first and second housings, a first sealing member extending as to be disposed between an inner surface of the first housing, an inner surface of the second housing, and an outer surface of the flexible display, and an elastic support member disposed between a portion of the flexible display, a portion of the inner surface of the first housing, and a portion of the inner surface of the second housing, within a folding area in which the first housing and the second housing are foldable and unfoldable. 
     According to certain embodiments of the disclosure, an electronic device includes a hinge module, a first housing to which a first side of the hinge module and at least a portion of a first support plate are coupled, the first housing including a first side surface, a second side surface, and a third side surface, a second housing to which a second side of the hinge module and at least a portion of a second support plate are coupled, the second housing including a fourth side surface, a fifth side surface, and a sixth side surface, wherein the second housing is foldable and unfoldable with the first housing about a folding axis defined by the hinge module, a flexible display spanning at least a portion of the first housing and the second housing, wherein the flexible display is foldable and unfoldable along with folding and unfolding of the first and second housings, and a first sealing member extending as to be disposed between an inner surface of the first housing, an inner surface of the second housing, and an outer surface of the flexible display 
     Certain embodiments of the disclosure provide an electronic device in which a sealing member (e.g., adhesive member) integrally extends between an outer surface of a flexible display and an inner surface of housings (e.g., first housing and second housing), which may thus provide waterproofing and/or dustproofing, protecting the foldable device against intrusion by moisture and/or foreign substances. 
     Certain embodiments of the disclosure provide an electronic device including an elastic support member that is disposed between a sealing member positioned adjacent to a folding area of the two housings and an inner surface of the two housings, which thus prevents the sealing member from being ejected out of the housing in certain physical configurations of the electronic device. 
     Further, various effects recognized directly or indirectly through certain embodiments of the disclosure can be provided.

Although certain embodiments of the disclosure have been described with respect to a foldable electronic device folded or unfolded in a vertical direction, the same may be applied to a foldable electronic device folded or unfolded in a horizontal direction. 
     With reference to  FIGS. 1A to 2B , an electronic device  100  according to certain embodiments of the disclosure may include a pair of housings (e.g., a first housing  110  and a second housing  120 ) (e.g., foldable housing) that are foldable relative to one another via a hinge module (e.g., a hinge module  140  of  FIG. 1B  or  FIG. 3 ). In some embodiments, the hinge module (e.g., the hinge module  140  of  FIG. 1B  or  FIG. 3 ) may be disposed in an X-axis direction (e.g., horizontal direction) or a Y-axis direction (e.g., longitudinal direction). In some embodiments, two or more hinge modules (e.g., the hinge module  140  of  FIG. 1B  or  FIG. 3 ) may be disposed to be folded in the same direction or in different directions. 
     According to certain embodiments, the electronic device  100  may include a flexible display  130  (e.g., foldable display) spanning at least a portion of a surface formed by the pair of housings  110  and  120 . The first housing  110  and the second housing  120  may be disposed at both sides about a folding axis (axis A) and have a substantially symmetrical shape with respect to the folding axis (axis A). The first housing  110  and the second housing  120  may have different angles or distances from each other according to whether the electronic device  100  is in an unfolded or flat state, a folded state, or an intermediate state. 
     According to certain embodiments, the pair of housings  110  and  120  may include a first housing  110  (e.g., first housing structure) coupled to a first side of the hinge module (e.g., the hinge module  140  of  FIG. 1B  or  FIG. 3 ) and a second housing  120  (e.g., second housing structure) coupled to a second side of the hinge module (e.g., the hinge module  140  of  FIG. 1B  or  FIG. 3 ). In the unfolded state, the first housing  110  may include a first surface  111  facing in a first direction (e.g., a front (z-axis) direction) and a second surface  112  facing in a second direction (e.g., a rear (−z-axis) direction) opposite to the first direction. In the unfolded state, the second housing  120  may include a third surface  121  facing in a first direction (e.g., z-axis direction) and a fourth surface  122  facing in a second direction (e.g., −z-axis direction).

The second side frame  123  may be formed in a rectangular (e.g., square or rectangular) shape through the fourth side surface  123   a , the fifth side surface  123   b , and the sixth side surface  123   c.    
     According to certain embodiments, the pair of housings  110  and  120  are not limited to the illustrated shape and coupling, and may be implemented by other combinations and/or couplings of other shapes or components. For example, the first side frame  113  may be integrally formed with the first rear cover  114 , and the second side frame  123  may be integrally formed with the second rear cover  124 . 
     According to certain embodiments, in the unfolded state of the electronic device  100 , the second side surface  113   b  of the first side frame  113  and the fifth side surface  123   b  of the second side frame  123  may be connected without any gap. In the unfolded state of the electronic device  100 , the third side surface  113   c  of the first side frame  113  and the sixth side surface  123   c  of the second side frame  123  may be connected without any gap. In the unfolded state, a combined length of the second side surface  113   b  and the fifth side surface  123   b  may be longer than a length of the first side surface  113   a  and/or the fourth side surface  123   a . Likewise, a combined length of the third side surface  113   c  and the sixth side surface  123   c  may be longer than a length of the first side surface  113   a  and/or the fourth side surface  123   a.    
     According to certain embodiments, the first side frame  113  and/or the second side frame  123  may be made of a metal, and/or may further include a polymer injected into the metal.

In this case, the at least one conductive portion  116  and/or  126  may be electrically connected to a wireless communication circuit disposed on a printed circuit board (not illustrated) of the electronic device  100 , thereby serving as an antenna operating in at least one specified band (e.g., legacy band). 
     According to certain embodiments, the first rear cover  114  and/or the second rear cover  124  may be formed by, for example, at least one of coated or colored glass, ceramic, polymer, or metal (e.g., aluminum, stainless steel (STS), or magnesium) or a combination of at least two thereof. 
     According to certain embodiments, the flexible display  130  may extend from the first surface  111  of the first housing  110  to at least a portion of the third surface  121  of the second housing  120  across the hinge module (e.g., the hinge module  140  of  FIG. 1B ). For example, the flexible display  130  may include a first flat area  130   a  substantially corresponding to the first surface  111 , a second flat area  130   b  corresponding to the second surface  121 , and a folding area  130   c  (e.g., bending region) connecting the first flat area  130   a  and the second flat area  130   b , and corresponding positionally to the hinge module (e.g., the hinge module  140  of  FIG. 1B  or  FIG. 3 ). 
     According to an embodiment, the flexible display  130  may include an unbreakable (UB) type OLED display (e.g., curved display). However, the flexible display  130  is not limited thereto, and may include a flat type display of an on cell touch active matrix organic light-emitting diode (OCTA) type. 
     According to certain embodiments, in the flexible display  130 , an edge (e.g., outer surface) of the first flat area  130   a  may be disposed at an inner surface of the first housing  110 . In the flexible display  130 , an edge (e.g., outer surface) of the second flat area  130   b  may be disposed at an inner surface of the second housing  120 . An edge of the flexible display  130  may be protected through a protective cap (not illustrated) disposed in an area corresponding to the hinge module (e.g., the hinge module  140  of  FIG. 1B  or  FIG. 3 ).
