Description

foldable electronic device

[0001] Various embodiments disclosed in the present disclosure relate to foldable electronic devices, for example, to foldable electronic devices including an antenna and a rear assembly.

[0002] The term "electronic device" may refer to devices that perform specific functions according to an installed program, ranging from home appliances to electronic notebooks, portable multimedia players, mobile communication terminals, tablet PCs, video / audio devices, desktop / laptop computers, or in-vehicle navigation systems. For example, these electronic devices can output stored information as sound or video. As the integration density of electronic devices increases and ultra-high-speed, high-capacity wireless communication becomes commonplace, various functions can be integrated into a single electronic device, such as a mobile communication terminal. For example, not only communication functions but also entertainment functions such as games, multimedia functions such as music / video playback, communication and security functions for mobile banking, or functions such as schedule management and electronic wallets are being integrated into a single electronic device.

[0003] With the widespread use of personal or portable communication devices such as smartphones, user demand for portability and ease of use is increasing. For example, a touchscreen display is an output device that outputs visual information, such as a screen, and can also provide a virtual keypad that replaces mechanical input devices (e.g., button-type input devices). As a result, portable communication devices or electronic devices can be miniaturized while providing the same or even better usability (e.g., a larger screen). On the other hand, with the commercialization of flexible displays, such as foldable or rollable displays, the portability and ease of use of electronic devices are expected to be further enhanced. Electronic devices including flexible displays can improve portability and ease of use by allowing multiple different structures (e.g., housings) to be carried in a folded or rolled state, and by providing a large screen when unfolded.

[0063] According to one embodiment, the first rear cover (280) is positioned on one side of the folding axis (Ax) at the rear of the electronic device (101) and may have a substantially rectangular periphery, for example, and the periphery may be wrapped by another structure of the first housing (210). Similarly, the second rear cover (290) is positioned on the other side of the folding axis (Ax) at the rear of the electronic device (101) and its periphery may be wrapped by another structure of the second housing (220).

[0064] According to one embodiment, the first rear cover (280) and / or the second rear cover (290) may have a substantially symmetrical shape with respect to the folding axis (Ax). However, the first rear cover (280) and the second rear cover (290) do not necessarily have mutually symmetrical shapes, and in one embodiment, the electronic device (101) may include the first rear cover (280) and the second rear cover (290) having different shapes that are not symmetrical.

[0065] According to one embodiment, the first rear cover (280), the second rear cover (290), the first housing (210), and the second housing (220) may provide a space in which various components of the electronic device (101) (e.g., a printed circuit board or a battery) may be placed.

[0067] According to one embodiment, the hinge cover (240) is positioned between the first housing (210) and the second housing (220) to cover an internal component (e.g., the hinge structure (202) of FIG. 4). According to one embodiment, the hinge cover (240) may be covered by a part of the first housing (210) and the second housing (220) or exposed to the outside, depending on the state of the electronic device (101) (flat state or folded state).

[0068] According to one embodiment, as shown in FIG. 2, when the electronic device (101) is in an unfolded state, the hinge cover (240) may be covered by the first housing (210) and the second housing (220) and not exposed. As another example, as shown in FIG. 3, when the electronic device (101) is in a folded state (e.g., a fully folded state), the hinge cover (240) may be exposed to the outside between the first housing (210) and the second housing (220). As yet another example, when the first housing (210) and the second housing (220) are in an intermediate state where they are folded with a certain angle, the hinge cover (240) may be partially exposed to the outside between the first housing (210) and the second housing (220). However, in this case, the exposed area may be smaller than in the fully folded state. In one embodiment, the hinge cover (240) may include a curved surface.

[0069] According to one embodiment, the display (230) may be placed in a space formed (or defined) by the housing (201). For example, the display (230) may be seated on a recess provided by the housing (201) and may form most of the front surface of the electronic device (101). Thus, the front surface of the electronic device (101) may include the display (230) and a portion of the first housing (210) and a portion of the second housing (220) adjacent to the display (230). The rear surface of the electronic device (101) may include a first rear cover (280), a portion of the first housing (210) adjacent to the first rear cover (280), a second rear cover (290), and a portion of the second housing (220) adjacent to the second rear cover (290).

[0070] According to one embodiment, the display (230) may include a plurality of display regions spaced apart from each other. For example, the display (230) may include a first display region (231) disposed on a first housing (210), a second display region (232) disposed on a second housing (220), and a folding region (233). According to one embodiment, the first display region (231) and the second display region (232) may rotate relative to each other with respect to a folding axis (Ax).

[0071] According to one embodiment, the display (230) may mean a display in which at least some area can be deformed into a flat or curved surface. For example, the display (230) may be a foldable or flexible display. According to one embodiment, the display (230) may include a folding area (233), a first display area (231) disposed on one side (e.g., the left side of the folding area (233) shown in FIG. 2) relative to the folding area (233), and a second display area (232) disposed on the other side (e.g., the right side of the folding area (233) shown in FIG. 2). However, the division of the areas of the display (230) is exemplary, and the display (230) may be divided into a plurality of areas (e.g., four or more or two) depending on the structure or function. For example, in the embodiment illustrated in FIG. 2, the area of ​​the display (230) may be divided by a folding area (233) extending parallel to the Y-axis or a folding axis (Ax), but in other embodiments, the area of ​​the display (230) may be divided based on a different folding area (e.g., a folding area parallel to the X-axis) or a different folding axis (e.g., a folding axis parallel to the X-axis). According to one embodiment, the display (230) may be combined with or placed adjacent to a touch detection circuit, a pressure sensor capable of measuring the intensity (pressure) of a touch, and / or a digitizer (not shown) configured to detect a magnetic field type stylus pen.

[0072] According to one embodiment, the first display area (231) and the second display area (232) may have a shape that is symmetrical overall with respect to the folding area (233). According to one embodiment (not shown), the second display area (232), unlike the first display area (231), may include a notch cut according to the presence of the sensor area (224), but may have a shape that is substantially symmetrical to the first display area (231) in other areas. For example, the first display area (231) and the second display area (232) may include a portion having a shape that is symmetrical to each other and a portion having a shape that is asymmetrical to each other.

[0073] Hereinafter, the operation of the first housing (210) and the second housing (220) and each area of ​​the display (230) according to the state of the electronic device (101) (e.g., flat state, or unfolded state and folded state) will be described.

The rear assembly (340) may be configured to secure the connector (3211) by covering the connector (3211) so that the flexible circuit board (330) is not separated from the connector (3211).

[0124] According to one embodiment, the rear assembly (340) may be positioned along at least a portion of the edge of the first printed circuit board assembly (321). For example, the rear assembly (340) may include a vertical portion (VP), a first horizontal portion (HP1), and / or a second horizontal portion (HP2). The vertical portion (VP) may be positioned in an edge region adjacent to the folding axis (F) of the first printed circuit board assembly (321) (e.g., the third side direction (+Y direction) side edge region of the first printed circuit board assembly (321).

The first horizontal portion (HP1) may be positioned in the first side direction (+X direction) side edge area of ​​the first printed circuit board assembly (321). The first horizontal portion (HP1) may extend in a direction intersecting the folding axis (F) (e.g., in the third side direction (+Y direction) and / or the fourth side direction (-Y direction)). The second horizontal portion (HP2) may be positioned in the second side direction (-X direction) side edge area of ​​the first printed circuit board assembly (321). The second horizontal portion (HP2) may extend in a direction intersecting the folding axis (F) (e.g., in the third side direction (+Y direction) and / or the fourth side direction (-Y direction)). By doing so, the rear assembly (340) of the first printed circuit board assembly (321) The edges can be securely fixed.

[0125] According to one embodiment, at least a portion of the rear assembly (340) may be adjacent to a side (e.g., outer surface) of the first housing portion (311).

For example, the first side direction (+X direction) portion of the rear assembly (340) may be adjacent to the side facing the first side direction (+X direction) of the first housing portion (311) and / or at least a portion of the antenna (3111).

[0126] According to one embodiment, the rear assembly (340) may include a metal part (341). For example, the metal part (341) may include SUS (steel used stainless steel). By including the metal part (341) in the rear assembly (340), the thickness of the rear assembly (340) can be reduced while maintaining sufficient rigidity of the rear assembly (340), so that space efficiency within the first housing part (311) can be improved.

[0127] According to one embodiment, the metal portion (341) may be configured to cover at least a portion of the connector (3211) (e.g., the first connector (3211a) and / or the second connector (3211b)). For example, a portion of the metal portion (341) may be placed on the connector (3211). For example, the connector (3211) may overlap the metal portion (341) in the first thickness direction (+Z direction) and / or the second thickness direction (-Z direction).

[0128] According to one embodiment, at least a portion of the metal part (341) may be positioned adjacent to the antenna (3111). For example, a portion of the metal part (341) may be positioned adjacent to the edge facing the first side direction (+X direction) and / or the edge facing the fourth side direction (-Y direction) of the first housing part (311).

[0129] According to one embodiment, the metal part (341) may include at least one segment (341a). The segment (341a) may be formed between the connector (3211) and the antenna (3111). The segment (341a) may be configured to segment the metal part (341). The segment (341a) may refer to a portion of the metal part (341) that is severed between a plurality of elements constituting the metal part (341). For example, the segment (341a) may be formed at one location between the connector (3211) and the antenna (3111). For example, the segment (341a) may be formed at a location adjacent to the folding axis (F). For example, the segment (341a) may be placed in a portion of the rear assembly (340) facing the third side direction (+Y direction) (e.g., the vertical portion (VP)). In one embodiment, the segmentation portion (341a) may be formed at multiple locations between the connector (3211) and the antenna (3111). Through the segmentation portion (341a), power generated from the power supply portion (3212) of the connector (3211) travels through the metal portion (341) to the antenna (3111), thereby preventing or mitigating the reduction in the radio wave reception sensitivity of the antenna (3111).

[0130] Table 1 below shows the low-band reception sensitivity of the antenna (3111) in the case where the metal part (341) is composed of one piece because the segmented part (341a) is not provided in the metal part (341) (Comparative Example), and in the case where the metal part (341) is composed of two pieces because of the segmented part (341a) (Experimental Example).

[0131] (Unit: dBm) Mode Band 5 Band 8 Band 20 Band 28 Band 12 Band 13 SUS 1-piece (Comparative Example) Open - 92.4 - 93.7 - 90.9 - 91.1 - 91.3 - 89.4 Close - 89.3 - 87.4 - 88.0 - 88.9 - 87.9 - 85.0 SUS 2-piece woven structure (Experimental Example) Open - 93.3 - 93.9 - 91.2 - 92.1 - 92.3 - 90.9 Close - 90.1 - 88.8 - 89.1 - 91.6 - 90.1 - 88.2 Improved Dose Open 0.8 0.3 0.2 1.0 1.0 1.6 Close 0.8 1.4 1.1 2.7 2.2 3.3

[0132] In [Table 1], 'Open' of 'Mode' refers to the unfolded state of the foldable electronic device (301) (e.g., the state of FIG. 2), and 'Close' of 'Mode' may refer to the folded state of the foldable electronic device (301) (e.g., the state of FIG. 3).

[0133] Referring to [Table 1], when the metal part (341) is provided with a segmented part (341a) and the metal part (341) is made up of two pieces (Experimental Example), compared to the case where the metal part (341) is not provided with a segmented part (341a) and the metal part (341) is made up of one piece (Comparative Example), it can be seen that the radio wave reception sensitivity of the antenna (3111) is improved for each band in both the unfolded state (e.g., state of FIG. 2) and the folded state (e.g., state of FIG. 3) of the foldable electronic device (301).

[0134] According to one embodiment, the metal portion (341) may include a first metal portion (3411). The first metal portion (3411) may be positioned on the connector (3211) side with respect to the segment portion (341a). For example, the first metal portion (3411) may be positioned to overlap the connector (3211). For example, the first metal portion (3411) may include a portion adjacent to the edge facing the third side direction (+Y direction) of the first housing portion (311) and a portion adjacent to the edge facing the second side direction (-X direction) of the first housing portion (311). For example, the first metal portion (3411) may include a portion positioned in an area adjacent to the right edge of the first printed circuit board assembly (321) and a portion positioned in an area adjacent to the bottom edge of the first printed circuit board assembly (321).

[0135] According to one embodiment, the metal portion (341) may include a second metal portion (3412). The second metal portion (3412) may be positioned on the antenna (3111) side with respect to the segment portion (341a). For example, the second metal portion (3412) may include a portion adjacent to the edge facing the first side direction (+X direction) of the first housing portion (311) and a portion adjacent to the edge facing the third side direction (+Y direction) of the first housing portion (311). For example, the second metal portion (3412) may include a portion positioned in an area adjacent to the upper edge of the first printed circuit board assembly (321) and a portion positioned in an area adjacent to the right edge of the first printed circuit board assembly (321). An end of the second metal portion (3412) may be adjacent to the edge facing the fourth side direction (-Y direction) of the first housing portion (311).

[0136] According to one embodiment, the first metal part (3411) and the second metal part (3412) may be spaced apart from each other. For example, the first metal part (3411) and the second metal part (3412) may be spaced apart from each other based on the segmented part (341a). For example, the first metal part (3411) and the second metal part (3412) may be spaced apart by at least 0.5 mm.

[0137] According to one embodiment, the first metal part (3411) and the second metal part (3412) may be connected by a non-metal part (342). The non-metal part (342) may be arranged to surround a portion of the first metal part (3411) adjacent to the second metal part (3412) and a portion of the second metal part (3412) adjacent to the first metal part (3411).

[0138] According to one embodiment, the rear assembly (340) may include a non-metallic part (342). The non-metallic part (342) may include a non-conductive member. For example, the non-metallic part (342) may include a material with high rigidity, heat resistance, impact resistance, and / or chemical resistance. For example, the non-metallic part (342) may include a PC-GF30 material in which glass fibers are added to polycarbonate.

[0139] According to one embodiment, the non-metallic part (342) may be disposed on at least the segmented part (341a). The non-metallic part (342) may be disposed between the metal parts (341) (e.g., the first metal part (3411) and the second metal part (3412)) disposed on both sides with respect to the segmented part (341a). The non-metallic part (342) may be configured to connect the segmented metal parts (341). For example, the non-metallic part (342) may be configured to wrap at least a portion of the first metal part (3411) and at least a portion of the second metal part (3412). For example, the non-metallic part (342) may be configured so that the rear assembly (340) is integrally formed. The non-metallic part (342) may be injection formed on the metal part (341). Since the rear assembly (340) is integrally formed through the segmented portion (341a), additional coupling holes for fixing each of the segmented metal portions (341) to the first housing portion (311) and / or the first printed circuit board assembly (321) do not need to be formed, so the space efficiency of the inner space of the first housing portion (311), the first printed circuit board assembly (321), and / or the rear assembly (340) can be improved. In addition, since the rear assembly (340) is integrally formed, the rear assembly (340) can more effectively fix the first printed circuit board assembly (321) to the first housing portion (311).

[0140] According to one embodiment, the non-metallic portion (342) may be placed in an area other than the segmented portion (341a). For example, the non-metallic portion (342) may be placed in at least a portion of the rear assembly (340) adjacent to the edge of the first housing portion (311). For example, referring to FIG. 5, the non-metallic portion (342) may be placed in a portion adjacent to the antenna (3111) of the first housing portion (311) (e.g., the edge facing the first side direction (+X direction) and the edge facing the fourth side direction (-Y direction) of the first housing portion (311), the edge facing the fourth side direction (-Y direction) of the first housing portion (311) (e.g., an antenna portion other than the antenna (3111) described above) and / or a portion adjacent to the edge facing the first side direction (+X direction) (e.g., an antenna portion other than the antenna (3111) described above). By placing a non-metallic part (342) in an adjacent area of ​​an antenna (e.g., antenna (3111)) placed at the edge of the first housing part (311), the signal reception sensitivity of the antenna (3111) can be improved.

[0141] According to one embodiment, the rear assembly (340) may include a coupling hole (H). The coupling hole (H) may be formed by penetrating the rear assembly (340). Multiple coupling holes (H) may be formed in the rear assembly (340). A coupling member (not shown) may be seated in the coupling hole (H). By fixing the coupling member to the first printed circuit board assembly (321) and / or the first housing portion (311) by penetrating the coupling hole (H), the first printed circuit board assembly (321) and / or the rear assembly (340) may be fixed to the first housing portion (311).

'Second side direction' may refer to the -X direction, which is the downward direction with respect to FIG. 9, and is the direction opposite to the first side direction (+X direction). 'Third side direction' may refer to the +Y direction, which is the right direction with respect to FIG. 9, and is the side direction perpendicular to the first side direction (+X direction) and / or the second side direction (-X direction). 'Fourth side direction' may refer to the -Y direction, which is the left direction with respect to FIG. 9, and is the direction opposite to the third side direction (+Y direction).

[0145] Hereinafter, 'first thickness direction' refers to one of the thickness directions of the rear assembly (340), and may mean the +Z direction, which is the upward direction based on FIG. 10. 'Second thickness direction' refers to a direction opposite to the first thickness direction (+Z direction), and may mean the -Z direction, which is the downward direction based on FIG. 10.

[0146] According to one embodiment, the first metal portion (3411) may include a first body portion (3411a). The first body portion (3411a) may include a portion having a plate shape. The first body portion (3411a) may overlap at least a portion of an electronic component (e.g., electronic component (E) of FIG. 7) placed on a first printed circuit board assembly (e.g., the first printed circuit board assembly (321) of FIG. 5 to 7) in the first thickness direction (+Z direction) and / or the second thickness direction (-Z direction). For example, the first body portion (3411a) may be configured to cover at least a portion of the electronic component (e.g., electronic component (E) of FIG. 7). Referring to FIG. 10, the first body portion (3411a) may form a portion of the upper surface of the rear assembly (340) (e.g., the surface facing the first thickness direction (+Z direction)).

[0147] According to one embodiment, the first metal part (3411) may include a first flange part (3411b). The first flange part (3411b) may protrude from the first body part (3411a) toward the second metal part (3412). For example, the first flange part (3411b) may protrude from the first body part (3411a) toward a first side direction (+X direction). The first flange part (3411b) may be wrapped by a non-metal part (342). Through this, the first metal part (3411) and the second metal part (3412) can be firmly fixed to each other.

[0148] According to one embodiment, the first flange portion (3411b) may be positioned at a stepped position from the first body portion (3411a). For example, a stepped structure (SS) may be formed between the first body portion (3411a) and the first flange portion (3411b). For example, the first flange portion (3411b) may be positioned closer to the first printed circuit board assembly (e.g., the first printed circuit board assembly (321) of FIG. 5 and 6) than to the first body portion (3411a). For example, referring to FIG. 10, the first flange portion (3411b) may be positioned at a lower position than the first body portion (3411a) (e.g., on the second thickness direction (-Z direction) side). For example, since the first body portion (3411a) is positioned in a location that overlaps with the electronic component (E), it needs to be positioned relatively far from the first printed circuit board assembly (321) to prevent interference with the electronic component (E), but since the first flange portion (3411b) is positioned in a location that does not overlap with the electronic component (E), it can be understood that it may be positioned closer to the first printed circuit board assembly (321) than the first body portion (3411a). Through this, the non-metallic part (342) can be placed not only on the lower part of the first flange part (3411b) (e.g., the part on the second thickness direction (-Z direction) of the first flange part (3411b)) but also on the upper part of the first flange part (3411b) (e.g., the part on the first thickness direction (+Z direction) of the first flange part (3411b)), and since the non-metallic part (342) can completely surround the first flange part (3411b), sufficient bonding force can be secured between the first metal part (3411) and the non-metallic part (342), and the rigidity of the rear assembly (340) can be improved.

[0149] According to one embodiment, the first flange portion (3411b) may have a width of at least 0.5 mm in a direction perpendicular to the first side direction (+X direction) (e.g., the third side direction (+Y direction) and / or the fourth side direction (-Y direction), horizontal direction with respect to FIG. 9). For example, the first flange portion (3411b) may have a width of about 1.25 mm in the third side direction (+Y direction) and / or the fourth side direction (-Y direction).

[0150] According to one embodiment, the first flange portion (3411b) may have a length of at least 1 mm in the first side direction (+X direction) (e.g., vertical direction with respect to FIG. 9). For example, the first flange portion (3411b) may have a length of about 1.8455 mm in the first side direction (+X direction).

[0151] According to one embodiment, the first metal part (3411) may include a first connecting part (3411c). The first connecting part (3411c) may be disposed between the first body part (3411a) and the first flange part (3411b). The first connecting part (3411c) may be configured to connect the first body part (3411a) and the first flange part (3411b). The first connecting part (3411c) may be disposed in the stepped structure (SS) of the first metal part (3411). For example, the stepped structure (SS) of the first metal part (3411) may be formed by the first connecting part (3411c).

[0152] According to one embodiment, the non-metal portion (342) may be configured to surround at least a portion of the first flange portion (3411b) and at least a portion of the first connecting portion (3411c). By doing so, the first metal portion (3411) can be firmly fixed to the non-metal portion (342).

[0153] According to one embodiment, the second metal portion (3412) may include a second body portion (3412a). The second body portion (3412a) may include a portion having a plate shape. The second body portion (3412a) may overlap with at least a portion of an electronic component (e.g., electronic component (E) of FIG. 7) disposed on a first printed circuit board assembly (e.g., the first printed circuit board assembly (321) of FIG. 5 to 7) in the first thickness direction (+Z direction) and / or the second thickness direction (-Z direction). For example, the second body portion (3412a) may be configured to cover at least a portion of the electronic component (e.g., electronic component (E) of FIG. 7). Referring to FIG. 10, the second body portion (3412a) may constitute a portion of the upper surface of the rear assembly (340) (e.g., the surface facing the first thickness direction (+Z direction)).

[0154] According to one embodiment, the second metal part (3412) may include a second flange part (3412b). The second flange part (3412b) may protrude from the second body part (3412a) toward the first body part (3411a). For example, the second flange part (3412b) may protrude from the second body part (3412a) toward the second side direction (-X direction). The second flange part (3412b) may be wrapped by a non-metal part (342). Through a structure in which the second flange part (3412b) is wrapped by the non-metal part (342), the first metal part (3411) and the second metal part (3412) can be firmly fixed to each other.

[0155] According to one embodiment, the second flange portion (3412b) may be positioned at a stepped position from the second body portion (3412a). For example, a stepped structure (SS) may be formed between the second body portion (3412a) and the first flange portion (3412b). For example, the second flange portion (3412b) may be positioned closer to the first printed circuit board assembly (e.g., the first printed circuit board assembly (321) of FIG. 5 and 6) than to the second body portion (3412a). For example, referring to FIG. 10, the second flange portion (3412b) may be positioned at a lower position than the second body portion (3412a) (e.g., on the second thickness direction (-Z direction) side). For example, since the second body portion (3412a) is positioned in a location that overlaps with the electronic component (E), it needs to be positioned relatively far from the first printed circuit board assembly (321) to prevent interference with the electronic component (E), but since the second flange portion (3412b) is positioned in a location that does not overlap with the electronic component (E), it can be understood that it may be positioned closer to the first printed circuit board assembly (321) than the second body portion (3412a). Through this, the non-metallic part (342) can be placed not only on the lower part of the second flange part (3412b) (e.g., the part on the second thickness direction (-Z direction) of the second flange part (3412b)) but also on the upper part of the second flange part (3412b) (e.g., the part on the first thickness direction (+Z direction) of the second flange part (3412b)), and since the non-metallic part (342) can completely surround the second flange part (3412b), sufficient bonding force can be secured between the second metal part (3412) and the non-metallic part (342), and the rigidity of the rear assembly (340) can be improved.

[0156] According to one embodiment, the second flange portion (3412b) may have a width of at least 0.5 mm in a direction perpendicular to the first side direction (+X direction) (e.g., the third side direction (+Y direction) and / or the fourth side direction (-Y direction), horizontal direction with respect to FIG. 9). For example, the second flange portion (3412b) may have a width of about 1.25 mm in the third side direction (+Y direction) and / or the fourth side direction (-Y direction).

[0157] According to one embodiment, the second flange portion (3412b) may have a length of at least 1 mm in the first side direction (+X direction) (e.g., vertical direction with respect to FIG. 9). For example, the second flange portion (3412b) may have a length of about 1.8455 mm in the first side direction (+X direction).

[0158] According to one embodiment, the second metal part (3412) may include a second connecting part (3412c). The second connecting part (3412c) may be disposed between the second body part (3412a) and the second flange part (3412b). The second connecting part (3412c) may be configured to connect the second body part (3412a) and the second flange part (3412b). The second connecting part (3412c) may be disposed in the stepped structure (SS) of the second metal part (3412). For example, the stepped structure (SS) of the second metal part (3412) may be formed by the second connecting part (3412c).

[0159] According to one embodiment, the non-metal portion (342) may be configured to surround at least a portion of the second flange portion (3412b) and at least a portion of the second connecting portion (3412c). By doing so, the first metal portion (3411) can be firmly fixed to the non-metal portion (342).

[0160] According to one embodiment, the first flange portion (3411b) and the second flange portion (3412b) may be spaced apart from each other when viewed from the first side direction (+X direction). For example, the first flange portion (3411b) and the second flange portion (3412b) may be understood not to overlap each other in the first side direction (+X direction) and / or the second side direction (-X direction). This allows sufficient length to be secured in the first side direction (+X direction) and / or the second side direction (-X direction) of each of the first flange portion (3411b) and the second flange portion (3412b). Through this, the contact area between the first flange portion (3411b) and / or the second flange portion (3412b) and the non-metal portion (342) can be increased, so the bonding force between the first metal portion (3411) and the second metal portion (3412) and the non-metal portion (342) can be improved.

[0161] According to one embodiment, the non-metallic portion (342) may be configured to surround at least a portion of the first metal portion (3411) and at least a portion of the second metal portion (3412). The non-metallic portion (342) may be configured to surround the first flange portion (3411b) and the second flange portion (3412b). The non-metallic portion (342) may be configured to surround at least a portion of the first flange portion (3411b), the first connecting portion (3411c), the second flange portion (3412b), and at least a portion of the second connecting portion (3412c). For example, the first metal part (3411) and the second metal part (3412) can be understood as being fixed to each other through a structure in which the first flange part (3411b) and the second flange part (3412b) are inserted into the non-metal part (342) located at the segment part (341a). In this way, through a structure in which the first flange part (3411b) and the second flange part (3412b) are wrapped around the non-metal part (342), the contact area between the first metal part (3411) and the second metal part (3412) and the non-metal part (342) can be increased, so the bonding force between the first metal part (3411) and the second metal part (3412) and the non-metal part (342) can be improved.

[0162] According to one embodiment, the first metal part (3411) and the second metal part (3412) may overlap at least partially in a side direction perpendicular to the first side direction (+X direction) (e.g., a third side direction (+Y direction) and / or a fourth side direction (-Y direction)). For example, the first flange part (3411b) and the second flange part (3412b) may overlap at least partially when viewed from the third side direction (+Y direction) and / or the fourth side direction (-Y direction) intersecting the first side direction (+X direction). For example, the first flange part (3411b) and the second flange part (3412b) may face each other at least partially in the third side direction (+Y direction) and / or the fourth side direction (-Y direction). For example, the first flange portion (3411b) and the second flange portion (3412b) may overlap by at least 0.5 mm in the third side direction (+Y direction) and / or the fourth side direction (-Y direction). Through this, the first metal portion (3411) and the second metal portion (3412) can be more firmly joined by the non-metal portion (342).

[0163] According to one embodiment, a structure in which a first metal part (3411) includes a first flange part (3411b) and a second metal part (3412) includes a second flange part (3412b), and the first flange part (3411b) and the second flange part (3412b) are spaced apart from each other when viewed from a first side direction (+X direction) and / or a second side direction (-X direction) and are arranged to overlap in a third side direction (+Y direction) and / or a fourth side direction (-Y direction), and the first flange part (3411b) and the second flange part (3412b) are wrapped by a non-metal part (342) may be referred to as a 'woven structure'.

[0164] FIG. 11 is a perspective view of an electronic device according to one embodiment of the present disclosure. FIG. 12 is an exploded perspective view of an electronic device according to one embodiment of the present disclosure.

[0165] Specifically, FIGS. 11 and FIGS. 12 illustrate a bar-type electronic device (401).

[0166] The detailed configuration of an electronic device (401) according to one embodiment of the present disclosure not described below may be the same or similar as the detailed configuration of the electronic device (101) described in relation to FIGS. 2 to 4 and / or the foldable electronic device (301) described in relation to FIGS. 5 to 10.

[0167] According to one embodiment, the electronic device (401) may include a housing (410). The housing (410) may accommodate electronic components such as a printed circuit board assembly (420) or a battery (402). A display (403) may be placed on the housing (410).

[0168] According to one embodiment, the housing (410) may include at least one antenna (4111). The antenna (4111) may be disposed on the outer surface of the housing (410). For example, the antenna (4111) may constitute part of the side (e.g., outer surface) of the housing (410). For example, at least the edge facing the first side direction (+X direction) and / or the edge facing the fourth side direction (-Y direction) of the housing (410) may be the antenna (4111).

[0170] The detailed configuration of the first printed circuit board assembly (421) not described above may be the same or similar to the detailed configuration of the first printed circuit board assembly (321) described in relation to FIGS. 5 to 7. For example, the first printed circuit board assembly (421) may be the same or similar to the first printed circuit board assembly (321) of FIGS. 5 to 7, except that the first connector (3211a) configuration to which the first flexible circuit board (330a) connecting the first printed circuit board assembly (321) and the second printed circuit board assembly (322) is connected is not provided.

[0171] According to one embodiment, the electronic device (401) may include a second printed circuit board assembly (422). The second printed circuit board assembly (422) may be placed inside the housing (410). The second printed circuit board assembly (422) may be placed on the other side of the battery (402). For example, the second printed circuit board assembly (422) may be placed on the second side direction (-X direction) side of the battery (402). The second printed circuit board assembly (422) may be referred to as the 'printed circuit board assembly (420)'.

[0172] The detailed configuration of the second printed circuit board assembly (422) not described above may be the same or similar as the detailed configuration of the third circuit board (265) described in relation to FIG. 4.

[0173] According to one embodiment, a printed circuit board assembly (420) (e.g., a first printed circuit board assembly (421)) may include a connector (4211). The connector (4211) may be the same or similar as the second connector (3211b) of FIG. 7. For example, the connector (4211) may be placed in a lower area of ​​the first printed circuit board assembly (421) (e.g., an area facing the second side direction (-X direction)). A flexible circuit board (430) may be connected to the connector (4211).

[0174] According to one embodiment, the connector (4211) may include at least one power supply unit (4212). The detailed configuration of the power supply unit (4212) may be the same or similar as the detailed configuration of the second power supply unit (3212b) described in relation to FIG. 6 "G" and FIG. 7. For example, power supplied through a charging terminal (4112) disposed on the second printed circuit board assembly (422) may be transmitted to the connector (4211) through the second printed circuit board assembly (422) and the flexible circuit board (430). The power supply unit (4212) may supply power to electronic components disposed on the first printed circuit board assembly (421). Noise caused by the power may occur in the power supply unit (4212).

[0175] According to one embodiment, the electronic device (401) may include a flexible circuit board (430). The flexible circuit board (430) may be configured to connect a first printed circuit board assembly (421) and a second printed circuit board assembly (422). The flexible circuit board (430) may be connected to a connector (4211). The detailed configuration of the flexible circuit board (430) not described above may be the same or similar to the detailed configuration of the second flexible circuit board (430) described in relation to FIGS. 5 and 6.

[0176] According to one embodiment, the electronic device (401) may include a rear assembly (440). The rear assembly (440) may be configured to cover at least a portion of the first printed circuit board assembly (421). The rear assembly (440) may be configured to cover a connector (4211).

[0177] According to one embodiment, the rear assembly (440) may include a metal part (441) (e.g., a first metal part (4411) and / or a second metal part (4412)) adjacent to at least one antenna (4111). The rear assembly (440) may include a non-metal part (442) connected to the metal part (441). The metal part (441) may include at least one segmented part (441a) formed between the connector (4211) and the antenna (4111) and configured to segment the metal part (441). The non-metal part (442) may be disposed on at least one segmented part (441a). The non-metal part (442) may be configured to connect the segmented metal part (441).

[0178] The detailed configuration of the rear assembly (440) not described above may be the same or similar to the detailed configuration of the rear assembly (340) described in relation to FIGS. 5 to 10.

[0179] The foldable electronic device includes a flexible printed circuit board (FPCB) for transferring power from a battery disposed in each of the first housing portion and the second housing portion to a printed circuit board assembly (PBA) disposed in each of the first housing portion and the second housing portion. The printed circuit board assembly includes a connector to which the terminals of the flexible printed circuit board are connected, and the connector includes a power supply unit (VPH_PWR) for supplying power to an electronic component disposed on the printed circuit board. The power supply unit generates various noises by the power supply.

[0180] Meanwhile, the foldable electronic device includes a rear assembly that fixes a printed circuit board assembly to a structure of a first housing portion and serves as a structure for mounting electronic components. The rear assembly is placed on the printed circuit board assembly. In particular, the rear assembly is placed to cover a connector to which a flexible circuit board is connected, specifically a power portion of the connector.

[0181] Recently, there have been ongoing attempts to reduce the thickness of foldable electronic devices. Accordingly, a structure has been introduced that can reduce the thickness while ensuring the strength of the rear assembly by replacing at least a portion of the rear assembly, which was previously manufactured using injection molding, with a metal component (e.g., SUS (steel used stainless)). This rear assembly had a structure in which the metal component was placed on the power portion of the connector.

[0182] However, in conventional rear assemblies, the metal member is provided as a single unit without being segmented, so noise generated from the power supply unit is induced along the rear assembly to the antenna placed on the outer surface of the housing part, and consequently, there was a problem of reduced reception sensitivity of the antenna.

[0183] In addition, even if a metal member is simply segmented into multiple pieces, additional coupling holes (e.g., boss holes) are required to fix each metal member to the printed circuit board assembly and / or housing part, which reduces space efficiency.

[0184] The problem to be solved in the present disclosure is to solve the problem in which noise generated in the power supply of a printed circuit board assembly is induced to the antenna along the rear assembly, thereby reducing the reception sensitivity of the antenna.

[0185] The problem to be solved in the present disclosure is to effectively fix a plurality of segmented metal members to provide a single rear assembly, thereby preventing the reduction of space efficiency caused by separate coupling holes.

[0186] The problems to be solved in this disclosure are not limited to those mentioned above, and may be determined in various ways without departing from the spirit and scope of this disclosure.

[0187] A foldable electronic device according to various embodiments of the present disclosure can prevent or mitigate the degradation of the antenna's reception sensitivity by improving the problem of noise generated in the power supply of a printed circuit board assembly being induced along the rear assembly.
