The width of the first adhesive layer (181) (e.g., the length between the right and left sides of the first adhesive layer (181) in FIG. 5) may be smaller than or equal to the width of the seating surface (115) of the first housing (110) (e.g., the width along the x-axis direction in FIG. 5).

[0066] According to one embodiment, the first adhesive layer (181) may be formed in a strip shape having a constant width, but is not limited thereto. For example, the shape of the first adhesive layer (181) may have different shapes and / or different widths in some sections depending on the shape of the seating surface (115) of the first housing (110) (e.g., the planar shape of the seating surface (115)). For example, some sections of the first adhesive layer (181) may be formed in a convex or concave curve shape. Some sections of the first adhesive layer (181) may be formed with a different width from other sections. In this way, the first adhesive layer (181) may be attached in a closed loop shape along the seating surface (115) of the first housing (110).

[0067] According to one embodiment, the first adhesive layer (181) may include a protruding portion (183) to which the first connecting layer (185) is attached. For example, during the process of manufacturing the adhesive member (180), a separate third adhesive layer (183) may be laminated on the upper surface of the first adhesive layer (181). The third adhesive layer (183) may be pressed with a predetermined pressure while laminated on the upper surface of the first adhesive layer (181). The third adhesive layer (183) may be formed integrally with the first adhesive layer (181) and may form a part of the first adhesive layer (181). The third adhesive layer (183) may be made of substantially the same material as the first adhesive layer (181). Since the protruding portion (183) of the first adhesive layer (181) and the third adhesive layer (183) have substantially the same configuration, they are assigned the same reference numeral.

[0068] According to one embodiment, the second adhesive layer (182) may form the upper surface of the adhesive member (180), and the upper surface of the second adhesive layer (182) may be the second surface (180b) of the adhesive member (180). The second adhesive layer (182) may be attached along a portion of the inner surface (160a) of the cover (160). For example, a portion of the inner surface (160a) of the cover (160) may be an area adjacent to the outer edge of the cover (160).

[0069] According to one embodiment, the second adhesive layer (182) may be formed to correspond to the first adhesive layer (181). Accordingly, the width of the second adhesive layer (182) may be substantially the same as the width of the first adhesive layer (181). The second adhesive layer (182) may be attached in a closed loop form along the inner surface (160a) of the cover (160).

[0070] According to one embodiment, the first connecting layer (185) may be disposed between the protruding portion (183) of the first adhesive layer (181) and the second adhesive layer (182). For example, the lower surface of the first connecting layer (185) may be attached to the upper surface of the protruding portion (183) of the first adhesive layer (181). The upper surface of the first connecting layer (185) may be attached to the lower surface of the second adhesive layer (182).

[0071] According to one embodiment, the first connecting layer (185) may include a material having stiffness. In this case, the first connecting layer (185) may include a material having adhesiveness. For example, the first connecting layer (185) may be configured in the form of a double-sided tape having adhesive applied to both sides of a film comprising a polyester (e.g., polyethylene terephthalate (PET)) or acrylic (e.g., polymethyl methacrylate (PMMA)) material. For example, if the material of the first connecting layer (185) includes acrylic, the film may be formed in the form of a thick foam.

[0072] For example, when the first connecting layer (185) is pressed between the first adhesive layer (181) and the second adhesive layer (182) at room temperature, the lower surface of the first connecting layer (185) can be connected to the first adhesive layer (181) with mutually determined bonding strength, and the upper surface of the first connecting layer (185) can be connected to the second adhesive layer (182) with mutually determined bonding strength. Accordingly, even if the cover (160) moves away from the housing (110) in the z-axis direction of FIG. 5 due to battery swelling (or is pushed), the first connecting layer (185) is strongly bonded to the first adhesive layer (181) and the third adhesive layer (183) by its rigidity and adhesiveness, so that the first adhesive layer (181) and the third adhesive layer (183) are not separated from each other and can maintain a solid connection state.

[0073] According to one embodiment, the second connecting layer (187) may be disposed between the first adhesive layer (181) and the second adhesive layer (182). For example, the second connecting layer (187) may be disposed parallel to the first connecting layer (185). For example, the first connecting layer (185) may be disposed outside the adhesive member (180) formed in a closed loop shape. The second connecting layer (187) may be disposed outside the adhesive member (180) formed in a closed loop shape.

[0074] According to one embodiment, the second connecting layer (187) may include an elastic material. In this case, the second connecting layer (187) may include an adhesive material. For example, the second connecting layer (187) may include a low-rebound high-compression sponge (e.g., a polyurethane (PU) material or a silicone-based material). If the second connecting layer (187) includes a polyurethane material, it has excellent flexibility and elasticity so that it can stretch without breaking when the battery swells. If the second connecting layer (187) includes a silicone-based material, it can be stable in high-temperature environments and its durability can be improved.

[0075] According to one embodiment, a space (189) may be provided between the first connecting layer (185) and the second connecting layer (187). For example, the second connecting layer (187) may be extended by elasticity in the z-axis direction of FIG. 5 when the cover (160) moves away from the housing (110) due to battery swelling. In this case, the second connecting layer (187) may be extended without interfering with the first connecting layer (185) as it is spaced apart from the first connecting layer (185) by a predetermined distance due to the space (189). Since the second connecting layer (187) has adhesive properties, it may be strongly bonded to the first adhesive layer (181) and the second adhesive layer (182), respectively, so that a solid connection state can be maintained so as not to be separated from the first adhesive layer (181) when the second connecting layer (187) is elastically extended due to battery swelling.

[0076] FIG. 6 is a drawing showing the state in which the battery (170) of an electronic device according to one embodiment of the present disclosure is swollen.

[0077] For example, a battery (170) (e.g., a lithium-ion battery) may swell (e.g., battery swelling) due to an internal short circuit, a charge state exceeding the allowed current or voltage, exposure to high temperatures, a drop, or impact caused by extreme changes in external atmospheric pressure.

[0078] For example, before battery swelling occurs, the lower surface (160a) of the cover (160) may be positioned with a gap (d) from the upper surface (170a) of the battery (170), as shown in FIG. 5. However, even before battery swelling occurs, the lower surface (160a) of the cover (160) may be in close proximity to or in contact with the upper surface (170a) of the battery (170) without a gap.

[0079] Referring to FIG. 6, when battery swelling occurs, the cover (160) may be moved away from the housing (110) by the swelling battery (170) along a direction (e.g., z-axis direction). In this case, the upper surface (170a) of the battery (170) may be pressed against the lower surface (160a) of the cover (160). The second adhesive layer (182) of the adhesive member (180) may be moved along the z-axis direction together with the cover (160).

[0080] According to one embodiment, the second connecting layer (187) of the adhesive member (180) can be elastically extended in the direction in which the cover (160) moves. The extended length of the second connecting layer (187) may correspond approximately to the height of the battery (170) being swollen. In this way, as the second connecting layer (187) is elastically extended, the displacement of the cover (160) is compensated so that the cover (160) does not separate from the housing (110) and the adhesive member (180). The first connecting layer (185) of the adhesive member (180) can maintain an interconnected state so that the first adhesive layer (181) and the second adhesive layer (182) do not separate. Therefore, since the housing (110) and the cover (160) can remain connected by an adhesive member (180), it is possible to improve the ingress of dust or moisture between the housing (110) and the cover (160) from the outside of the electronic device (10).

[0081] FIGS. 7, FIGS. 8, FIGS. 9, FIGS. 10, FIGS. 11, FIGS. 12, FIGS. 13, and FIGS. 14 are drawings illustrating the manufacturing process of an adhesive member (180) according to one embodiment of the present disclosure. The manufacturing process of an adhesive member (180) according to one embodiment will be described with reference to the drawings.

[0082] Referring to FIG. 7, after aligning the first adhesive sheet (183a) and the first connecting sheet (185a), the first connecting sheet (185a) is laminated onto the upper surface of the first adhesive sheet (183a). The first adhesive sheet (183a) and the first connecting sheet (185a) can be pressed at room temperature with a predetermined pressure to form the first laminated member (183a, 185a).

[0083] For example, the first adhesive sheet (183a) may be configured to form the third adhesive layer (183) of the adhesive member (180) illustrated in FIG. 5. For example, the first adhesive sheet (183a) may include a PSA. For example, the first connecting sheet (185a) may be configured to form the first connecting layer (185) of the adhesive member (180) illustrated in FIG. 5. Since the first connecting sheet (185a) may include a material having rigidity, it may also be referred to as a rigid sheet. The first connecting sheet (185a) may include a material having adhesiveness. Therefore, when the first connecting sheet (185a) is pressed while laminated to the first adhesive sheet (183a), the first adhesive sheet (183a) and the first adhesive sheet (183a) can form a strong bonded structure due to the adhesive force.

[0084] Referring to FIG. 8, the first laminated member (183a, 185a) can be cut along the first cutting line (L1) and the second cutting line (L2) provided on the first laminated member (183a, 185a). For example, the first and second cutting lines (L1, L2) may be virtual lines provided by a cutting machine (not shown).

[0085] For example, a portion of the first laminated member (183a, 185a) cut from the first laminated member (183a, 185a) may be a second laminated member (183, 185) having a closed-loop shape. The second laminated member (183, 185) may include a configuration corresponding to the third adhesive layer (183) and the first connecting layer (185) of the adhesive member (180) shown in FIG. 5, respectively.

[0086] Referring to FIG. 9, the outer portion of the first elastic sheet (187a) can be cut along a third cutting line (L3) provided on the first elastic sheet (187a). For example, the third cutting line may have a closed-loop shape offset by a predetermined distance inward from the second cutting line. The third cutting line (L3) may be a virtual line provided by a cutting machine (not shown). For example, the portion of the first elastic sheet (187a) cut from the first elastic sheet (187a) may be the second elastic sheet (187b).

[0087] Referring to FIG. 10, a second laminated member (183, 185) can be laminated on the upper surface of the second adhesive sheet (181a). For example, the second adhesive sheet (181a) may be configured to form the first adhesive layer (181) of the adhesive member (180) shown in FIG. 5. For example, the second adhesive sheet (181a) may be made of substantially the same material as the first adhesive sheet (183a).

[0088] For example, a portion of the second laminated member (183, 185) (e.g., the third adhesive layer (183)) may be attached to the upper surface of the second adhesive sheet (181a). The portion of the second laminated member (183, 185) (e.g., the third adhesive layer (183)) and the second adhesive sheet (181a) may be formed integrally by a subsequent pressing process.

[0089] Referring to FIG. 11, a second elastic sheet (187b) can be laminated on the upper surface of a second adhesive sheet (181a). For example, the second elastic sheet (187b) can be placed on the inner side of a second laminated member (183, 185). In this case, a space (189) can be provided between the outer edge of the second elastic sheet (187b) and the inner edge of the second laminated member (183, 185).

[0090] Referring to FIG. 12, a third adhesive sheet (182a) can be laminated on the upper surface of the second laminated member (183, 185) and the second elastic sheet (187b). The third adhesive sheet (182a) can be pressed toward the second adhesive sheet (181a) at a predetermined pressure at room temperature. Accordingly, the second adhesive sheet (181a) can form a strong bonding structure with the second laminated member (183, 185) and the second elastic sheet (187b), respectively, by means of adhesive force.

[0091] Referring to FIGS. 13 and 14, a second adhesive sheet (181a, see FIG. 12), a third adhesive sheet (182a), and a second elastic sheet (187b) can be cut along a fourth cutting line (L4) and a fifth cutting line (L5) provided on a third adhesive sheet (182a) to form an adhesive member (180). For example, the fourth cutting line (L4) may correspond to the outer edge of the second laminated member (183, 185). The fourth cutting line (L4) may correspond to the outer edge of the adhesive member (180) shown in FIG. 5 (e.g., the side adjacent to the outer edge (113) of the housing (110) in FIG. 5). The fifth cutting line (L5) may correspond to the inner edge of the adhesive member (180) shown in FIG. 5. The fourth and fifth cutting lines (L4, L5) may be virtual lines provided by a cutting machine (not shown).

[0092] The adhesive member (180) produced through such a process may include a first adhesive layer (181), a second adhesive layer (182), a third adhesive layer (183), a first connecting layer (185), and a second connecting layer (187).

[0093] FIGS. 15 and 16 are drawings illustrating an example of connecting a cover (160) to a housing (e.g., a first housing (110)) using an adhesive member (180) according to one embodiment of the present disclosure. The process of attaching the cover (160) to the housing (110) using the adhesive member (180) will be described with reference to the drawings.

[0094] Referring to FIG. 15, a battery (170) can be inserted into a receiving groove (111) of a housing (110). An adhesive member (180) can be attached along a seating surface (115) of the housing (110). In this case, a first adhesive layer of the adhesive member (180) (e.g., see reference numeral 181 in FIG. 14) can be attached to the seating surface (115) of the housing (110).

[0095] Referring to FIG. 16, a cover (160) is attached to the rear surface of a housing (110). In this case, the cover (160) can be attached to a second adhesive layer of an adhesive member (180) (e.g., see reference numeral 182 in FIG. 14). For example, while the cover (160) is attached to the adhesive member (180), the cover (160) can be pressed along the z-axis of FIG. 16 with a predetermined pressure toward the housing (110) at room temperature. In this case, the first adhesive layer (181) of the adhesive member (180) can form a strong bond structure with the seating surface (115) of the housing (110) by means of adhesive force. The second adhesive layer (182) of the adhesive member (180) can form a strong bond structure with the lower surface (160a) of the cover (160) by means of adhesive force.

[0096] For example, the adhesive member (180) can be placed between the housing (110) and the cover (160) while rotated about 180 degrees around the y-axis of FIG. 16, and the cover (160) can be pressed toward the housing (110). In this case, the first adhesive layer (181) of the adhesive member (180) can be attached to the lower surface (160a) of the cover (160), and the second adhesive layer (182) of the adhesive member (180) can be attached to the seating surface (115) of the housing (110).

[0097] FIG. 17 is a plan view showing an adhesive member (180-1) of an electronic device according to one embodiment of the present disclosure.

[0098] According to one embodiment, the adhesive member (180-1) may include a plurality of first connecting layers (185-1) and second connecting layers (187-1). For example, as shown in FIG. 17, one first connecting layer (185-1) may be placed in each of the first part (180c-1) of the adhesive member (180-1) and the second part (180d-1) of the adhesive member (180-1) corresponding to the first part (180c-1). The length of the third part (180e-1) connecting the first part (180c-1) and the second part (180d-1) of the adhesive member (180-1), and the length of the fourth part (180f-1) of the adhesive member (180-1) corresponding to the third part (180e-1), may be formed to be longer than the length of the first part (180c-1) and the second part (180d-1) of the adhesive member (180-1). In this case, two first connecting layers (185-1) may be placed in each of the third part (180e-1) and the fourth part (180f-1) of the adhesive member (180-1). For example, the second connecting layer (187-1) may include a number corresponding to each of the plurality of first connecting layers (185-1). In this case, the length of the second connecting layer (187-1) may be substantially the same as the length of the first connecting layer (185-1).

[0099] For example, the first connecting layer (185-1) and the second connecting layer (187-1) of the adhesive member (180-1) may be arranged in equal numbers on the first, second, third, and fourth parts (180c-1, 180d-1, 180e-1, 180f-1) of the adhesive member (180-1).

[0100] For example, the first connecting layer (185-1) and the second connecting layer (187-1) of the adhesive member (180-1) may be arranged in different numbers depending on the lengths of the first, second, third, and fourth parts (180c-1, 180d-1, 180e-1, 180f-1) of the adhesive member (180-1).

[0101] FIG. 18 is a perspective view showing an adhesive member (180-2) of an electronic device according to one embodiment of the present disclosure.

[0102] The adhesive member (180) shown in FIG. 14 has a roughly rectangular strip shape, and two of the four adjacent corners may be rounded with a defined curvature, while the remaining two corners may be formed at approximately right angles, but are not limited thereto.

[0103] For example, as shown in FIG. 18, the adhesive member (180-2) may have four corners (180g-2, 180h-2, 180i-2, 180j-2) each having the same shape. For example, the four corners (180g-2, 180h-2, 180i-2, 180j-2) of the adhesive member (180-2) may be rounded to have curvature. For example, the four corners (180g-2, 180h-2, 180i-2, 180j-2) of the adhesive member (180-2) may all have a roughly right-angle shape.

[0104] For example, the adhesive member (180-2) is not limited to a roughly rectangular strip shape. The adhesive member (180-2) may have a polygonal, circular, or elliptical strip shape depending on the seating surface (e.g., 115 in FIG. 5) of the housing (e.g., 180 in FIG. 5).

[0105] FIG. 19 is a cross-sectional view showing an example in which an adhesive member (180-3) of an electronic device (10-3) according to one embodiment of the present disclosure is disposed between a housing (e.g., a first housing (110-3)) and a cover (160-3)).

[0106] Referring to FIG. 19, the electronic device (10-3) according to one embodiment may be mostly identical to the configuration of the electronic device (10) described with reference to FIG. 1 and FIG. 5. For example, the electronic device (10-3) may include an adhesive member (180-3) attached to a seating surface (115-3) of a housing (110-3). A cover (160-3) may be attached to the housing (110-3) by the adhesive member (180-3).

[0107] According to one embodiment, the adhesive member (180-3) may have substantially the same configuration as the adhesive member (180) described with reference to FIG. 5. For example, the adhesive member (180-3) may include a first adhesive layer (181-3), a second adhesive layer (182-3), a third adhesive layer (183-3) formed integrally with the first adhesive layer (181-3) (or a protruding portion (183-3) of the first adhesive layer (181-3)), a first connecting layer (185-3) attached between the second adhesive layer (182-3) and the third adhesive layer (183-3), and a second connecting layer (187-3) attached between the first adhesive layer (181-3) and the second adhesive layer (182-3).

[0108] According to one embodiment, the adhesive member (180-3) may differ from the adhesive member (180) described with reference to FIG. 5 in that the space between the first connecting layer (185-3) and the second connecting layer (187-3) is omitted. In this case, one side of the second connecting layer (187-3) (e.g., the left side of the second connecting layer in FIG. 19) may be in contact with the first connecting layer (185-3) and the third adhesive layer (183-3).

[0109] FIG. 20 is a cross-sectional view showing an example in which an adhesive member (180-4) of an electronic device (10-4) according to one embodiment of the present disclosure is disposed between a housing (e.g., a first housing (110-4)) and a cover (160-4). FIG. 21 is a drawing showing a swollen state of a battery (170-4) of an electronic device (10-4) according to one embodiment of the present disclosure.

[0110] Referring to FIG. 20, the electronic device (10-4) according to one embodiment may be mostly identical to the configuration of the electronic device (10) described with reference to FIG. 1 and FIG. 5. For example, the electronic device (10-4) may include an adhesive member (180-4) attached to a seating surface (115-4) of a housing (110-4). A cover (160-4) may be attached to the housing (110-4) by the adhesive member (180-4).

[0111] According to one embodiment, the adhesive member (180-4) may have substantially the same configuration as the adhesive member (180) described with reference to FIG. 5. For example, the adhesive member (180-4) may include a first adhesive layer (181-4), a second adhesive layer (182-4), a third adhesive layer (183-4) formed integrally with the first adhesive layer (181-4) (or a protruding portion (183-4) of the first adhesive layer (181-4)), a first connecting layer (185-4) attached between the second adhesive layer (182-4) and the third adhesive layer (183-4), and a second connecting layer (187-4) attached between the first adhesive layer (181-4) and the second adhesive layer (182-4).

[0112] According to one embodiment, the adhesive member (180-4) may have different positions for the first connecting layer (185-4), the second connecting layer (187-4), and the third adhesive layer (183-4) compared to the adhesive member (180) described with reference to FIG. 5. For example, the third adhesive layer (183-4) and the first connecting layer (185-4) may be located on the inside of the adhesive member (180-4) (e.g., to the right of the adhesive member (180-4) in FIG. 20). The second connecting layer (187-4) may be located on the outside of the adhesive member (180-4) (e.g., to the left of the adhesive member (180-4) in FIG. 20). The first connecting layer (185-4) and the second connecting layer (187-4) may be spaced apart from each other with a space (189-4) in between.

[0113] Referring to FIG. 21, if battery swelling occurs, the cover (160-4) may be moved along a direction away from the housing (110-4) by the swelling battery (170-4) (e.g., the z-axis direction in FIG. 21). The second adhesive layer (182-4) of the adhesive member (180-4) may be moved along the z-axis direction together with the cover (160-4). In this case, the second connecting layer (187-4) of the adhesive member (180-4) may be elastically extended in the direction in which the cover (160-4) is moved so that the first adhesive layer (181-4) and the second adhesive layer (182-4) remain interconnected. Accordingly, the second connecting layer (187-4) of the adhesive member (180-4) can compensate for the displacement of the cover (160-4) and improve the separation of the cover (160-4) from the housing (110-4).

[0114] In this way, even when the first connecting layer (185-4) of the adhesive member (180-4) is placed on the inside of the adhesive member (180-4) and the second connecting layer (187-4) of the adhesive member (180-4) is placed on the outside of the adhesive member (180-4), substantially the same effect can be obtained through the adhesive member (180) described with reference to FIG. 6.

[0115] FIG. 22 is a cross-sectional view showing an example in which an adhesive member (180-5) of an electronic device (10-5) according to one embodiment of the present disclosure is disposed between a housing (e.g., a first housing (110-5)) and a cover (160-5). FIG. 23 is a drawing showing a swollen state of a battery (170-5) of an electronic device (10-5) according to one embodiment of the present disclosure.

[0116] Referring to FIG. 22, an electronic device (10-5) according to one embodiment may have a configuration mostly identical to that of the electronic device (10) described with reference to FIG. 1 and FIG. 5. For example, the electronic device (10-5) may include an adhesive member (180-5) attached to a seating surface (115-5) of a housing (110-5). A cover (160-5) may be attached to the housing (110-5) by the adhesive member (180-5).

[0117] According to one embodiment, the adhesive member (180-5) may include a first adhesive layer (181-5), a second adhesive layer (182-5), and a connecting layer (187-5).

[0118] According to one embodiment, the first adhesive layer (181-5) and the second adhesive layer (182-5) may include, but are not limited to, a pressure-sensitive adhesive (PSA). For example, the first adhesive layer (181-5) and the second adhesive layer (182-5) may include a UV-curing adhesive, a hot-melt adhesive, and / or an epoxy adhesive.

[0119] According to one embodiment, the first adhesive layer (181-5) may be attached along the seating surface (115-5) of the first housing (110-5). The width of the first adhesive layer (181-5) (e.g., the length between the right and left sides of the first adhesive layer (181-5) in FIG. 22) may be smaller than the width of the seating surface (115-5) of the first housing (110-5) (e.g., the width along the x-axis direction in FIG. 22). For example, the first adhesive layer (181-5) may be formed in a strip shape having a constant width and may be attached in a closed loop form along the seating surface (115-5) of the first housing (110-5).

[0120] According to one embodiment, the second adhesive layer (182-5) may be attached along a portion of the inner surface (160a-5) of the cover (160-5). For example, the portion of the inner surface (160a-5) of the cover (160-5) may be an area adjacent to the outer edge of the cover (160-5). For example, the second adhesive layer (182-5) may be formed in a strip shape having a constant width similar to the first adhesive layer (181-5). In this case, the width of the second adhesive layer (182-5) (e.g., the length between the right and left sides of the second adhesive layer (182-5) in FIG. 22) may be greater than the width of the first adhesive layer (181-5). The second adhesive layer (182-5) may be attached in a closed loop shape along the inner surface (160a-5) of the cover (160-5).

[0121] According to one embodiment, a second adhesive layer (182-5) may be disposed between the seating surface (115-5) of the housing (110-5) and the second adhesive layer (187-5). For example, the connecting layer (187-5) may be disposed parallel to the first adhesive layer (181-5). In this case, the connecting layer (187-5) may be disposed inside the adhesive member (180-5) formed in a closed loop shape, but is not limited thereto. For example, the connecting layer (187-5) may be disposed outside the adhesive member (180-5) formed in a closed loop shape. In this case, the first adhesive layer (181-5) may be disposed inside the adhesive member (180-5). For example, the connecting layer (187-5) may include an elastic material. In this case, the connecting layer (187-5) may include an adhesive material.

[0122] Referring to FIG. 23, if battery swelling occurs, the cover (160-5) may be moved along a direction away from the housing (110-5) by the swelling battery (170-5) (e.g., the z-axis direction in FIG. 23). In this case, the upper surface (170a-5) of the battery (170-5) may be pressed against the lower surface (160a-5) of the cover (160-5). The second adhesive layer (182-5) of the adhesive member (180-5) may be moved along the z-axis direction together with the cover (160-5). In this case, as the second adhesive layer (182-5) moves along the z-axis direction, the upper part of the first adhesive layer (181-5) may be deformed and partially extended along the z-axis direction together with the second adhesive layer (182-5).

[0123] The connecting layer (187-5) of the adhesive member (180-5) can be elastically extended in the direction in which the cover (160-5) moves. In this case, the lower surface of the connecting layer (187-5) can be maintained attached to the seating surface (115-5) of the housing (110-5). Thus, the connecting layer (187-5) of the adhesive member (180-5) can compensate for the displacement of the cover (160-5) and improve the separation of the cover (160-5) from the housing (110-5).

[0124] FIG. 24 is a cross-sectional view showing an example in which an adhesive member (180-6) of an electronic device (10-6) according to one embodiment of the present disclosure is disposed between a housing (e.g., a first housing (110-6)) and a cover (160-6). FIG. 25 is a drawing showing a swollen state of a battery (170-6) of an electronic device (10-6) according to one embodiment of the present disclosure.

[0125] Referring to FIG. 24, the electronic device (10-6) according to one embodiment may be mostly identical to the configuration of the electronic device (10) described with reference to FIG. 1 and FIG. 5. For example, the electronic device (10-6) may include an adhesive member (180-6) attached to a seating surface (115-6) of a housing (110-6). A cover (160-6) may be attached to the housing (110-6) by the adhesive member (180-6).

[0126] According to one embodiment, the adhesive member (180-6) may include a first adhesive layer (181-6), a second adhesive layer (182-6), a pair of third adhesive layers (183a-6, 183b-6), and a connecting layer (187-6).

[0127] According to one embodiment, the first adhesive layer (181-6), the second adhesive layer (182-6), and the third adhesive layer (183a-6, 183b-6) may comprise a pressure-sensitive adhesive (PSA), but are not limited thereto. For example, the first adhesive layer (181-6), the second adhesive layer (182-6), and the third adhesive layer (183a-6, 183b-6) may comprise a UV-curing adhesive, a hot-melt adhesive, and / or an epoxy adhesive.

[0128] According to one embodiment, the first adhesive layer (181-6) may be attached along the seating surface (115-6) of the first housing (110-6). The width of the first adhesive layer (181-6) (e.g., the length between the right and left sides of the first adhesive layer (181-6) in FIG. 24) may be smaller than or equal to the width of the seating surface (111-6) of the first housing (110-6) (e.g., the width along the x-axis direction in FIG. 24). For example, the first adhesive layer (181-6) may be formed in a strip shape having a constant width and may be attached in a closed loop form along the seating surface (115-6) of the first housing (110-6).

[0129] According to one embodiment, the second adhesive layer (182-6) may be attached along a portion of the inner surface (160a-6) of the cover (160-6). For example, the portion of the inner surface (160a-6) of the cover (160-5) may be an area adjacent to the outer edge of the cover (160-6). For example, the second adhesive layer (182-6) may be formed in a strip shape having a constant width similar to the first adhesive layer (181-6). In this case, the width of the second adhesive layer (182-6) (e.g., the length between the right and left sides of the second adhesive layer (182-6) in FIG. 25) may be substantially the same as the width of the first adhesive layer (181-6). The second adhesive layer (182-6) may be attached in a closed loop shape along the inner surface (160a-6) of the cover (160-6).

[0130] According to one embodiment, a pair of third adhesive layers (183a-6, 183b-6) may be spaced apart from each other between the first adhesive layer (181-6) and the second adhesive layer (182-6). In this case, the pair of third adhesive layers (183a-6, 183b-6) may be placed on one side (e.g., the left side of the adhesive member (180-6) in FIG. 24) and the other side (e.g., the right side of the adhesive member (180-6) in FIG. 24), respectively, of the adhesive member (180-6). For example, the pair of third adhesive layers (183a-6, 183b-6) may have a width smaller than the width of the first adhesive layer (181-6) and the second adhesive layer (182-6).

[0131] According to one embodiment, the connecting layer (187-6) may be disposed between the first adhesive layer (181) and the second adhesive layer (182). In this case, the connecting layer (187-6) may be disposed between a pair of third adhesive layers (183a-6, 183b-6). The connecting layer (187-6) may be spaced apart from the pair of third adhesive layers (183a-6, 183b-6) by spaces (189a-6, 189b-6) provided on both sides. For example, the connecting layer (187-6) may include an elastic material. In this case, the connecting layer (187-6) may include an adhesive material.

[0132] Referring to FIG. 25, when battery swelling occurs, the cover (160-6) may be moved along a direction away from the housing (110-6) by the swelling battery (170-6) (e.g., the z-axis direction in FIG. 25). In this case, the upper surface (170a-6) of the battery (170-6) may be pressed against the lower surface (160a-6) of the cover (160-6). The second adhesive layer (182-6) of the adhesive member (180-6) may be moved along the z-axis direction together with the cover (160-6). The second connecting layer (187-6) can be extended without interfering with the pair of third adhesive layers (183a-6, 183b-6) as it is spaced apart from the pair of third adhesive layers (183a-6, 183b-6) by a space (189a-6, 189b-6). The upper portion of the pair of third adhesive layers (183a-6, 183b-6) can be deformed as the second adhesive layer (182-6) moves in the z-axis direction and can be extended in part in the z-axis direction together with the second adhesive layer (182-6).

[0133] For example, the connecting layer (187-6) of the adhesive member (180-6) can be elastically extended in the direction in which the cover (160-6) moves. In this case, the lower surface of the connecting layer (187-6) can remain attached to the first adhesive layer (181-6). Thus, the connecting layer (187-6) of the adhesive member (180-6) can compensate for the displacement of the cover (160-6) and improve the separation of the cover (160-6) from the housing (110-6).
