That is, when a component is said to be placed above another component, it can mean that the component is placed along the Z-axis with respect to the other component, and when a component is said to be placed below another component, it can mean that the component is placed in the direction opposite to the Z-axis with respect to the other component. On the other hand, it should be noted that even if a component is placed above or below another component, it does not mean that the entire component is located above or below all of the other components. For example, a part of a component may be placed above a part of another component, but another part of the component may be placed below a part of another component. It should be noted that when a component is said to overlap (or stack) another component in the following description, the description of the arrangement relationship in the height direction described above can be applied. In the description of the direction, if 'yin / yang (- / +)' is not stated, it can be interpreted as facing the + direction unless otherwise defined.For example, 'Z-axis direction' can be interpreted as pointing toward the +Z direction, 'X-axis direction' can be interpreted as pointing toward the +X-axis direction, and 'Y-axis direction' can be interpreted as pointing toward the +Y-axis direction. In describing directions, pointing toward any one of the three axes of the orthogonal coordinate system can include pointing in a direction parallel to the axis. According to one embodiment of the present disclosure, 'X-axis direction' can be referred to as a 'first direction', and 'Z-axis direction' can be referred to as a 'second direction'. This is based on the orthogonal coordinate system described in the drawings for the sake of brevity of description, and it should be noted that the description of such directions or components does not limit one embodiment of the present disclosure.

[0092] Referring to FIGS. 6 to 22 below, each component included in the electronic device will be described in more detail.
[0093] FIG. 6 is a cross-sectional view of a portion of a housing component according to one embodiment of the present disclosure. FIG. 7 is a perspective view of a first portion according to one embodiment of the present disclosure.
[0094] Referring to FIGS. 6 and 7, the housing part (400) may include a first portion (410) and a second portion (420).
[0095] According to one embodiment, the first part (410) may be a part that can be visually and / or tactilely recognized by a user on the exterior of the electronic device (101). According to one embodiment, at least a part of the first part (410) may be in a form that surrounds at least a part of the second part (420). Therefore, in order to secure the rigidity of the electronic device (101), the first part (410) may include a metal material. For example, the metal material of the first part (410) may be, for example, stainless steel (SS 316, SS 316L), a titanium alloy material (e.g., TI6AL4V, TI6AL4V ELI, etc.), pure titanium (CpTi), or an aluminum alloy (e.g., AlSi10Mg). However, the present invention is not necessarily limited thereto, and according to an embodiment, the first part (410) may also include a non-metallic (e.g., resin) material.
[0096] According to one embodiment, the second part (420) may be disposed relatively inside the electronic device (101) compared to the first part (410) forming the exterior of the electronic device (101). According to one embodiment, the second part (420) may correspond to the inner surface of the housing part (400) surrounding the interior space of the electronic device (101). According to one embodiment, the second part (420) may include a material having a lower rigidity than the first part (410). According to one embodiment, the second part (420) may include a material having a lower density than the material of the first part (410). The second part (420) may include a material such as a metal material such as aluminum (AL), stainless steel (SUS), titanium (TiTan), ceramic, and an amorphous metal, and / or a non-metallic (e.g., resin) material.
[0097] According to one embodiment, the first part (410) may be formed of a metallic material, and the second part (420) may be formed of a non-metallic material, thereby providing a housing component (400) in which different materials are joined by a joining portion (422). According to another embodiment, both the first part (410) and the second part (420) may be formed of a metallic material, or both the first part (410) and the second part (420) may be formed of a non-metallic material. In this case, even if the first part (410) and the second part (420) are the same metal or non-metal, they may be formed of different metallic materials (e.g., the first part (410) is formed of a metallic material having higher rigidity than the second part (420), or they may be formed of different non-metallic materials (e.g., the first part (410) is formed of a non-metallic material having higher rigidity than the second part (420).
[0098] The second part (420) may be formed by injecting a molten material (e.g., molten metal or molten resin) into the first cavity (412) to form the second part (420), thereby joining the first part (410) and the second part (420) and thereby forming a joining portion (422) of the second part (420) to be described later. As described above, the first part (410) and the second part (420) may be joined to form a housing part (400).
[0099] According to one embodiment, since the first part (410) and the second part (420) having differences in rigidity and / or density are joined together, the housing part (400) can effectively protect the internal components of the electronic device (101), while the electronic device (101) can be made lighter by using lightweight materials inside.
[0100] In the embodiments of FIGS. 6 and 7 and below, the first cavity (412) is formed in the first part (410) constituting the exterior of the electronic device (101), but the present invention is not limited thereto. For example, the housing component (400) of the present disclosure may have a cavity (e.g., the first cavity (412, 512)) formed in the second part (420). According to one embodiment, a molten material for forming the first part (410) may be injected into the cavity (e.g., the first cavity (412, 512)) formed in the second part (420) and then solidified, so that the second part (420) and the first part (410) may be combined.
[0101] Referring to FIGS. 6 and 7, the first portion (410) may include a first body (411) and a first cavity (412).
[0102] According to one embodiment, the first body (411) may include a first body frame (4111) in which a first cavity (412) is formed. According to one embodiment, the first body (411) may further include a protrusion (4112) formed to protrude in a first direction (e.g., -X direction) from the first body frame (4111). The first body frame (4111) may include a rigid metal material to protect the interior of the electronic device (101). The protrusion (4112) may be formed to protrude in the first direction (e.g., -X direction) from the first body frame (4111). The protrusion (4112) may prevent the second part (420) from contacting other internal components of the electronic device (101) when the second part (420) is coupled with the first part (410). Specifically, when a molten material is injected into the first cavity (412) to form a shape of the second part (420), the molten material can be prevented from coming into contact with a part other than the first part (410).
[0103] According to one embodiment, the first cavity (412) may refer to a space formed inside the first part (410). The first cavity (412) may include a first opening (4121), a second opening (4122) spaced apart from the first opening (4121), and a first connecting hole (4123) formed between the first opening (4121) and the second opening (4122).
[0104] According to one embodiment, the first opening (4121) and the second opening (4122) may be formed by being sunken in the first direction (e.g., + X direction) of the first portion (410), and a molten material for forming the second portion (420) may be injected into the first portion (410) through the first opening (4121) and / or the second opening (4122), and the molten material may be solidified in the first cavity (412) to form a joining portion (422) to be described later.
[0105] According to one embodiment, the diameter of the cross-section of the first cavity (412) may be from 0.01 mm to 10 mm.
[0106] If the cross-sectional diameter of the first cavity (412) is 0.01 mm or less, it may be difficult to inject molten material to form the shape of the second part (420), and if the cross-sectional diameter of the first cavity (412) is 10 mm or more, as the electronic device (101) is miniaturized and lightweight, it may be difficult to utilize the housing component (400) in the miniaturized electronic device (101).
[0107] However, in the present embodiment and the following examples, the diameter of the cross-section of the first cavity (412) is described as being 0.01 mm to 10 mm, but depending on the size and type of the electronic device (101), the diameter of the cross-section of the first cavity (412) may be 0.1 mm or less or 10 mm or more.
[0108] In addition, although the cross-sectional diameters of the first opening (4121), the second opening (4122) and / or the first connection hole (4123) are described as being the same in the present embodiment and the following embodiments, this is not limited thereto, and the cross-sectional diameters of the first opening (4121), the second opening (4122) and / or the first connection hole (4123) may be different.
[0109] According to one embodiment, at least a portion of the first connection hole (4123) may include a curve. If at least a portion of the first connection hole (4123) includes a curve, the surface area of the first inner peripheral surface of the first portion (410) may be formed to be wider than if at least a portion of the first connection hole (4123) does not include a curve.
[0110] As the surface area of the first inner surface of the first part (410) increases, the bonding area between the first cavity (412) and the bonding portion (422) described later can increase. As a result, the first part (410) and the second part (420) can be bonded more strongly.
[0111] According to one embodiment, if at least a portion of the first cavity (412) is formed as a curve, the molten material for forming the shape of the second portion (420) can be easily injected into the first cavity (412), and if the first cavity (412) is formed as a whole curve, the molten material for forming the shape of the second portion (420) can easily fill the entire first cavity (412).
[0112] According to one embodiment, the first connecting hole (4123) is described as a first cavity (412) having a circular shape, and two openings (e.g., a first opening (4121) and a second opening (4122)) are formed in each of the first cavities (412), but the present invention is not limited thereto. For example, as shown in FIG. 21 and / or FIG. 22 described below, at least some of the cavities among the plurality of cavities (e.g., the first cavities (612, 712) of FIGS. 21 and 22) may be formed in a shape including two or more openings (e.g., the first openings (6121, 7121) of FIGS. 21 and 22).
[0113] In addition, when the joining portion (422) to be described later fills the entire first cavity (412) and the first cavity (412) and the joining portion (422) to be described later are joined, the joining area between the first cavity (412) and the joining portion (422) to be described later increases, so the first part (410) and the second part (420) can be joined more strongly.
[0114] According to one embodiment, the present invention and the following embodiments may be exemplified by the molten material for forming the second portion (420) filling the entire first cavity (412), but the present invention is not limited thereto, and may also fill a portion of the first cavity (412) depending on the shape of the first cavity (412).
[0115] According to one embodiment, the second part (420) may include a second body (421) and a connecting portion (422). The second body (421) may have a connecting portion (422) formed on one side thereof, and the connecting portion (422) may be disposed in the first connecting hole (4123) by penetrating the first opening (4121) and the second opening (4122) of the first cavity (412).
[0116] According to one embodiment, a molten material for forming a shape of the second part (420) is injected into the first cavity (412) and solidified, and a portion of the solidified second part (420) penetrating the first cavity (412) may be referred to as a joining part (422), and the joining part (422) may be formed according to the shape of the first cavity (412). Accordingly, the joining area between the first part (410) and the second part (420) may vary depending on the shape of the first cavity (412), and thus the joining force between the first part (410) and the second part (420) may vary.
[0117] According to one embodiment, in FIGS. 6 and 7, one first cavity (412) may be formed in the first part (410) of the housing component (400), but this is not limited thereto, and in the embodiments described below, a plurality of cavities (e.g., the first cavity (512)) may be formed in the first part (e.g., the first part (510)).
[0118] FIG. 8 is a drawing showing a portion of a housing component according to one embodiment of the present disclosure.
[0119] Referring to FIG. 8, the housing component (500) may include a first portion (510) and a second portion (520, 530). In FIG. 8, the first portion (510) is illustrated as a part of the side structure (310) and the second portion (520, 530) is illustrated as a part of the rear plate (380), but the present invention is not limited thereto, and the housing component (500) may be a part of a structure that a user can visually or tactilely perceive on the exterior of the electronic device (101). For example, it may be a part of structures forming the exterior of the electronic device (101) (e.g., the side structure (310), the front plate (320), the rear plate (380)).
[0120] FIG. 9 is a cross-sectional view illustrating a portion of a housing component of an electronic device along line A-A' of FIG. 8, according to one embodiment of the present disclosure. FIG. 10 is a perspective view of a first portion, according to one embodiment of the present disclosure.
[0121] Referring to FIGS. 9 and 10, the housing component (500) may include a first portion (510) and a second portion (520) including a plurality of first cavities (512).
[0122] According to one embodiment, the first portion (510) may include a first body (511) and a first cavity (512). In addition, the first body (511) may include a first body frame (5111) and a protrusion (5112), and the first cavity (512) may include a first opening (5121) and a second opening (5122) spaced apart from the first opening (5121).
[0123] According to one embodiment, a plurality of first cavities (512) having a regular structure may be repeatedly formed in the first portion (510), and some of the first cavities (512) may intersect each other, but the shape of the first cavities (512) is not limited thereto. For example, as shown in FIG. 21 and / or FIG. 22 described below, the plurality of cavities (e.g., the first cavities (612, 712) of FIG. 21 and FIG. 22) may have an irregular shape, and at least some of the cavities among the plurality of cavities may have a shape in which they intersect each other.
[0124] FIG. 11 is a drawing showing a portion of the first part cut along line A-A' of FIG. 10 according to one embodiment of the present disclosure.
[0125] Referring to FIG. 11, the first cavity (512) may include a first opening (5121), a second opening (5122), a first connecting hole (5123), a first inner surface (5124) of the first portion (510), and a first intersection area (5125).
[0126] According to one embodiment, each of the internal spaces of the plurality of first cavities (512) may be referred to as a first connecting hole (5123), and a molten material for forming a shape of the second part (520) is injected into the first cavity (512) through the plurality of first openings (5121) and / or second openings (5122), and the molten material is combined with the first inner surface (5124) of the first part (510), so that the first part (510) and the second part (520) may be combined.
[0127] According to one embodiment, at least a portion of a plurality of first connection holes (5123) may intersect, and at this time, the space where the first connection holes (5123) intersect may be referred to as a first intersection area (5125). When the first intersection area (5125) is formed, the surface area of the first inner peripheral surface (5124) of the first part (510) increases, and thus the first part (510) and the second part (520) may be more strongly coupled. Therefore, as the number of first intersection areas (5125) increases, the first part (510) and the second part (520) may be more strongly coupled.
[0128] FIG. 12 is a diagram showing a state before a second part is coupled with a first part and after a second part is coupled with a first part, according to one embodiment of the present disclosure.
[0129] Referring to FIG. 12, in relation to the combination of the first part (510) and the second part (520), the state before and after the second part (520) is combined with the first part (510) can be identified.
[0130] According to one embodiment, the shape of the first part (510) can be formed through a lamination process. If the shape of the first part (510) is formed through a lamination process, the first cavity (512) can be implemented not only on the surface of the first part (510) but also inside the first part (510), and the first cavity (512) of various shapes can be implemented inside the first part (510) without any separate restrictions.
[0131] According to one embodiment, when utilizing a lamination process, a first cavity (512) for bonding with a second portion (520) can be formed without performing any additional pretreatment on the first portion (510).
[0132] According to one embodiment, in order to implement the first cavity (512) inside, a high-precision layer-by-layer method may be applied, and among them, a PBF (Powder Bed Fusion) process may be applied.
[0133] The PBF process is a layering process that selectively melts or sinteres powdered materials to solidify them. After the shape of the first part (510) is layered through the PBF process, a heat treatment process may be performed to improve the durability and corrosion resistance of the layered first part (510). The roughness of the shape formed through the PBF process can generally have a value of 0.05 to 2 μm, and thus, the roughness of the first part (510) can have a value of 0.05 to 2 μm.
[0134] In the present invention and the following embodiments, a lamination process is used to form the shape of the first part (510), but the present invention is not limited thereto, and other processes (e.g., injection molding process, cutting process) may be used as long as the first part (510) including a plurality of first cavities (512) of the present invention can be implemented.
[0135] According to one embodiment, after forming the shape of the first part (510), a molten material for forming the shape of the second part (520) may be injected into the first cavity (512) of the first part (510) and then solidified to form the shape of the second part (520).
[0136] More specifically, a mold in which a third cavity is formed to form a second part (520) is placed adjacent to the first part (510) in which a first cavity (512) is formed, and a molten material is injected into the first cavity (512) and the third cavity, and then solidified to form the second part (520).
[0137] In one embodiment, an insert die casting process may be used to form the shape of the second portion (520). Specifically, through the insert die casting process, the molten material may be solidified in the first cavity (512) and the third cavity, thereby joining the first portion (510) and the second portion (520).
[0138] In the present invention and the following examples, the shape of the second part (520) is formed by an insert die casting process, but the present invention is not limited thereto. If at least a portion of the second part (520) is injected into the first cavity (512) of the first part (510) of the present invention so that the first part (510) and the second part (520) can be joined, the second part (520) can be formed by another process (e.g., a lamination process, an injection process).
[0139] In addition, when different materials are combined in the housing manufacturing process of an electronic device (101), a bonding force between the different materials is generally required to be at least 20 MPa in all areas. As shown in FIG. 12, when a molten material for forming the shape of the second part (520) is injected into the first cavity (512) and combined, the first part (510) and the second part (520) of the housing component (500) can be combined with a bonding force of at least 20 MPa, which is a bonding force generally required in the housing of an electronic device (101).
[0140] Fig. 13 is a cross-sectional view of a comparative example of a housing component according to one embodiment of the present disclosure. Fig. 14 is a cross-sectional view of a comparative example of a housing component according to one embodiment of the present disclosure.
[0141] Referring to FIGS. 13 and 14, these are illustrations for determining the difference in bonding strength depending on the shape of the first part (510), the second part (520), and / or the first cavity (512). Comparing the comparative examples and the embodiment of FIG. 10, when two or more openings (e.g., the first opening (5121) and the second opening (5122)) are formed in the first cavity (512), the first part (510) and the second part (520) can be bonded more strongly.
[0142] Specifically, when the materials of the first part (510; 510a; 510b) and the second part (520; 520a; 520b) and the depth of the first cavity (512; 512a; 512b) are the same, the bonding force of the embodiment of FIG. 8 can be 1.2 times stronger than the bonding force of the comparative example of FIG. 13, and 1.65 times stronger than the bonding force of the comparative example of FIG. 14.
[0143] For example, when the material of the first part is titanium, the material of the second part is aluminum, and the depth of the first cavity is 0.5 mm to 2.0 mm, the bonding force of the embodiment of Fig. 10 may be 132 MPa, the bonding force of the comparative example of Fig. 13 may be 110 MPa, and the bonding force of the comparative example of Fig. 14 may be 80 MPa.
[0144] In addition, since the first cavity (512a; 512b) of the comparative examples of FIGS. 13 and 14 has a shape implemented on the surface, a process of pre-processing the surface may be necessary after implementing the shape of the first cavity (512a; 512b), and the first part (510a; 510b) and the second part (520) may be separated even after joining.
[0145] FIG. 15 is a drawing showing a portion of a housing component according to one embodiment of the present disclosure. FIG. 16 is a drawing showing a portion of a housing component of an electronic device cut along line B-B' of FIG. 15 according to one embodiment of the present disclosure.
[0146] Referring to FIGS. 15 and 16, the first portion (510) of the housing component (500) may further include a second cavity (513) formed in the first cavity (512).
[0147] In one embodiment, as the second cavity (513) is further formed in the first portion (510), the depth of injection of the molten material for forming the shape of the second portion (520) can be increased. This allows for stronger bonding between the first portion (510) and the second portion (520).
[0148] FIG. 17 is a cross-sectional view of a first portion according to one embodiment of the present disclosure.
[0149] Referring to FIG. 17, the second cavity (513) may include a first connection hole opening (5131), a second connection hole opening (5132), a second connection hole (5133), a second inner surface (5134) of the first portion (510), and a second intersection area (5135).
[0150] According to one embodiment, the second cavity (513) may refer to a space formed inside the first cavity (512). In addition, a plurality of second cavities (513) may be formed in the first portion (510), and at least some of the plurality of second cavities (513) may be partially formed in a curved shape. In addition, at least some of the plurality of second cavities (513) may include two or more openings (e.g., a first connection hole opening (5131), a second connection hole opening (5132)).
[0151] In the present embodiment and the following embodiments, at least a portion of the second cavity (513) is formed in a circular shape, and two openings (e.g., a first connection hole opening (5131), a second connection hole opening (5132)) are formed in each of the second cavities (513), but this is not limited thereto. For example, a cavity formed inside the first part (510) excluding a cavity formed on the surface of the first part (510) (e.g., a first cavity (512)) and into which a molten material for forming a shape of the second part (520) can be injected may be referred to as a second cavity (513).
[0152] According to one embodiment, the first connection hole opening (5131) and the second connection hole opening (5132) may be formed on the first inner surface (5124) of the first portion (510). In addition, each inner space of the plurality of second cavities (513) may be referred to as a second connection hole (5133).
[0153] According to one embodiment, a molten material for forming a second portion (520) is injected into the second connecting hole (5133) and is combined with the second inner surface (5134) of the first portion (510) so that the first portion (510) and the second portion (520) can be combined.
[0154] In addition, at least a portion of a plurality of second connecting holes (5133) may intersect, and at this time, the space where the second connecting holes (5133) intersect may be referred to as a second intersection area (5135). When the second intersection area (5135) is formed, the area where the connecting portion (522) is connected may be wider, like the first intersection area (5125), and accordingly, the first part (510) and the second part (520) may be connected more strongly.
[0155] When a second cavity (513) is additionally implemented in the first part (510), the first part (510) and the second part (520) can be more strongly coupled. Specifically, the second cavity (513) can be additionally formed in the first part (510) to prevent the first part (510) and the second part (520) from being separated when the electronic device (101) is dropped.
[0156] FIG. 18 is a perspective view illustrating a portion of a housing component according to an embodiment of the present disclosure. FIG. 19 is a cross-sectional view illustrating a portion of a housing component of an electronic device along line C-C' of FIG. 18 according to an embodiment of the present disclosure. FIG. 20 is a cross-sectional view illustrating a portion of a housing component of an electronic device along line D-D' of FIG. 18 according to an embodiment of the present disclosure.
[0157] Referring to FIGS. 18 to 20, the second portions (520, 530) may include different materials.
[0158] According to one embodiment, a part of the second part (520, 530), for example, the 2-1 part (520), may be made of a metal material, and the 2-2 part (530) may be made of a non-metal material through an injection molding process. In addition, regardless of the material of the second part (520, 530), the first cavity (512) of the first part (510) may be formed, or the first cavity (512) and the second cavity (513) may be formed, and a molten material for forming the second part (520, 530) may be injected into the first cavity (512), or injected into the first cavity (512) and the second cavity (513), so that the first part (510) and the second part (520, 530) may be joined.
[0159] FIG. 21 is a cross-sectional view of a housing component according to one embodiment of the present disclosure. FIG. 22 is a cross-sectional view of a housing component according to one embodiment of the present disclosure.
[0160] Referring to FIGS. 21 and 22, an irregular cavity (612; 712) as illustrated may be implemented in the first portion (610; 710).
[0161] According to one embodiment, as shown in FIGS. 21 and 22, even when a high-strength metal is used for the frame of the electronic device (101), the cavity (612; 712) can be formed in an irregular shape in order to reduce material costs and reduce the weight of the electronic device (101).
[0162] Referring to FIG. 21, since the shape of the cavity (612) has an irregular shape, the embodiment of FIG. 21 has a bonding force similar to the comparative example of FIG. 13, but the injection depth of the molten material for forming the second portion (620) may be reduced.
[0163] Specifically, even though the embodiment of FIG. 21 and the comparative example of FIG. 13 have similar bonding strengths of about 110 MPa, the injection depth of the molten material for forming the second part (620) of the embodiment of FIG. 21 may be about 0.5 mm shorter than that of the comparative example of FIG. 13.
[0164] When the injection depth of the molten material is shortened, the width of the housing part (600) can be reduced, thereby miniaturizing and / or reducing the weight of the electronic device (101).
[0165] Referring to FIG. 22, by changing the shape of the cavity (712), the embodiment of FIG. 22 has the injection depth of the molten material for forming the second portion (720) as the comparative example of FIG. 13, but the embodiment of FIG. 22 can have a bonding force that is 1.2 times greater.
[0166] Specifically, even though the embodiment of FIG. 22 and the comparative example of FIG. 13 have similar injection depths of the molten material to form the second portion (720), the embodiment of FIG. 22 can have a bonding strength that is 1.2 times greater than that of the comparative example of FIG. 13.
[0167] Referring to FIGS. 21 and 22, if the bonding force is the same, since the shape of the cavity (612, 712) has an irregular shape, the depth at which the molten material for forming the second part (620; 720) penetrates can be shortened, thereby reducing the width of the housing part (600; 700), thereby miniaturizing and / or reducing the weight of the electronic device (101).

According to one embodiment of the present disclosure, an electronic device including a housing part (400; 500) comprises a first part (410; 510) including a first body (411; 511) and a first cavity (412; 512) formed in the first body, and a second part (420; 520) including a second body (421; 521) and a coupling part (422; 522) coupled to the first part (410; 520), wherein the first cavity (412; 512) comprises a first opening (4121; 5121) formed in a surface of the first part (410, 510) and a second opening (4122; 5122) formed in a surface of the first part (410, 510) and spaced apart from the first opening; An electronic device may be provided, comprising a first connection hole (4123; 5123) formed between the first opening and the second opening, and the coupling portion (422; 522) is disposed in the first connection hole (4123; 5123) by penetrating the first opening (4121; 5121) and / or the second opening (4122; 5122) of the first cavity (412; 512).
