These various types of communication modules can be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips). The wireless communication module (192) can verify or authenticate the electronic device (101) within a communication network such as the first network (198) or the second network (199) by using subscriber information (e.g., an international mobile subscriber identity (IMSI)) stored in the subscriber identification module (196).

[0043] The wireless communication module (192) can support 5G networks and next-generation communication technologies following the 4G network, such as NR access technology (new radio access technology). The NR access technology can support high-speed transmission of high-capacity data (eMBB (enhanced mobile broadband)), minimization of terminal power and connection of multiple terminals (mMTC (massive machine type communications)), or high reliability and low latency (URLLC (ultra-reliable and low-latency communications)). The wireless communication module (192) can support, for example, a high-frequency band (e.g., mmWave band) to achieve a high data transmission rate.

The sensor module (276) may be arranged in the electronic device (201) to correspond to a sensing area (261a-1) of a screen display area (261a). For example, the sensor module (276) may be arranged to perform its function without being visually exposed through the display (261) in an internal space of the electronic device (201). The sensor module (276) may receive an input signal penetrating the sensing area (261a-1) and generate an electrical signal based on the received input signal. For example, the input signal may have a specified physical quantity (e.g., heat, light, temperature, sound, pressure, ultrasound). In one embodiment, the input signal may include a signal relating to the user's biometric information (e.g., the user's fingerprint, voice).

[0061] In one embodiment, the electronic device (201) may include a camera module (280a, 380b) (e.g., the camera module (180) of FIG. 1).

[0062] In one embodiment, the first camera module (280a) is disposed on the front side (210a) of the housing (210) such that its lens is exposed, and can receive an optical signal from the front side (e.g., +Z direction) of the electronic device (201). The second camera module (280b) is disposed on the rear side (210b) of the housing (210) such that its lens is exposed, and can receive an optical signal from the rear side (e.g., -Z direction) of the electronic device (201). In one embodiment, at least a portion of the first camera module (280a) may be disposed on the housing (210) such that it is covered by the display (261). For example, the first camera module (280a) may include an under-display camera (UDC). In one embodiment, the first camera module (280a) may receive an optical signal that passes through the camera area (261a-2). In one embodiment, the second camera module (280b) may include multiple cameras (e.g., dual cameras, triple cameras, or quad cameras). In one embodiment, the flash (280c) may include a light-emitting diode or a xenon lamp.

[0063] In one embodiment, the electronic device (201) may include an input module (250) (e.g., the input module (150) of FIG. 1). The input module (250) may receive an operation signal from a user. For example, the input module (250) may include at least one key input device that is positioned so as to be exposed on a side surface (211c) of the housing (210).

[0064] In one embodiment, the electronic device (201) may include a connection terminal (278) (e.g., connection terminal (178) of FIG. 1). In one embodiment, the connection terminal (278) may be disposed on an outer surface of the housing (210). The electronic device (201) may be wired to an external device (e.g., another electronic device or an external power source) through the connection terminal (278).

[0065] In one embodiment, the electronic device (201) may include one or more printed circuit boards. For example, the electronic device (201) may include a first circuit board (251) (or a main circuit board) and a second circuit board (252) (or a sub-circuit board). The first circuit board (251) and the second circuit board (252) may be disposed inside the electronic device (201), for example, in a second support structure (242). At least one of the circuit boards (251, 252) may be connected to a support portion (242) via a ground. In one embodiment, the first circuit board (251) may be accommodated in a first substrate slot (242a) formed by the support portion (242). In one embodiment, the second circuit board (252) may be accommodated in the second board slot (242b) formed by the support portion (242).

Electronic devices according to embodiments disclosed herein are not limited to the aforementioned devices.

[0068] The various embodiments of this document and the terminology used therein are not intended to limit the technical features described in this document to specific embodiments, but should be understood to include various modifications, equivalents, or substitutes of the embodiments. In connection with the description of the drawings, similar reference numerals may be used for similar or related components. The singular form of a noun corresponding to an item may include one or more of the items, unless the context clearly indicates otherwise. In this document, each of the phrases "A or B", "at least one of A and B", "at least one of A or B", "A, B, or C", "at least one of A, B, and C", and "at least one of A, B, or C" can include any one of the items listed together in the corresponding phrase among those phrases, or all possible combinations thereof. Terms such as "first," "second," or "first" or "second" may be used merely to distinguish one component from another, and do not limit the components in any other respect (e.g., importance or order). When a component (e.g., a first component) is referred to as "coupled" or "connected" to another component (e.g., a second component), with or without the terms "functionally" or "communicatively," it means that the component can be connected to the other component directly (e.g., wired), wirelessly, or through a third component.

[0069] The term "module" used in various embodiments of this document may include a unit implemented in hardware, software, or firmware, and may be used interchangeably with terms such as logic, logic block, component, or circuit. A module may be an integral component, or a minimum unit or part of such a component that performs one or more functions.

[0070] Various embodiments of the present document may be implemented as software (e.g., a program (140)) including one or more instructions stored in a storage medium (e.g., an internal memory (136) or an external memory (138)) readable by a machine (e.g., an electronic device (101)). For example, a processor (e.g., a processor (120)) of the machine (e.g., an electronic device (101)) may call at least one instruction among the one or more instructions stored from the storage medium and execute it. This enables the machine to operate to perform at least one function according to the at least one called instruction. The one or more instructions may include code generated by a compiler or code executable by an interpreter. The machine-readable storage medium may be provided in the form of a non-transitory storage medium. Here, 'non-transitory' simply means that the storage medium is a tangible device and does not contain signals (e.g., electromagnetic waves), and the term does not distinguish between cases where data is stored semi-permanently or temporarily on the storage medium.

[0071] According to one embodiment, the method according to various embodiments disclosed in the present document may be provided as included in a computer program product. The computer program product may be traded as a product between a seller and a buyer. The computer program product may be distributed in the form of a machine-readable storage medium (e.g., compact disc read only memory (CD-ROM)), or may be distributed online (e.g., downloaded or uploaded) via an application store (e.g., Play Store™) or directly between two user devices (e.g., smart phones). In the case of online distribution, at least a portion of the computer program product may be temporarily stored or temporarily generated in a machine-readable storage medium, such as the memory of a manufacturer's server, an application store's server, or an intermediary server.

[0072] According to various embodiments, each component (e.g., a module or a program) of the above-described components may include one or more entities, and some of the entities may be separated and placed in other components.

In such a case, the integrated component may perform one or more functions of each of the plurality of components identically or similarly to those performed by the corresponding component among the plurality of components prior to the integration. According to various embodiments, the operations performed by a module, program, or other component may be executed sequentially, in parallel, iteratively, or heuristically, or one or more of the operations may be executed in a different order, omitted, or one or more other operations may be added.

[0073] Figure 3 is a usage state diagram of a case (390) according to one embodiment.

[0074] Referring to FIG. 3, a case (390) according to one embodiment can be detachably mounted on the outer surface of an electronic device (301) (e.g., electronic device (101) of FIG. 1, electronic device (201) of FIG. 2a).

[0075] In one embodiment, the electronic device (301) may be, but is not limited to, a portable smart phone as illustrated in FIG. 3, and may be, for example, a portable wireless communication device or display device such as a tablet PC, a notebook PC, or a personal digital assistant (PDA). In one embodiment, the electronic device (301) may include a display positioned on the front (e.g., the display (261) of FIG. 2A).

[0076] In one embodiment, the case (390) may be mounted on the outer surface of the electronic device (301) to protect the exterior of the electronic device (301). For example, the case (390) may absorb or buffer shock applied from the outside of the electronic device (301) to protect the electronic device (301) from external shock. In one embodiment, the case (390) may protect the electronic device (301) from external contaminants (e.g., foreign substances, moisture) by covering at least a portion of the electronic device (301). In one embodiment, the case (390) may be mounted on the outer surface of the electronic device (301) to cover at least a portion of the outer surface of the electronic device (301), for example, the back surface of the electronic device (301) (e.g., the back surface (210b) of the electronic device (301) in FIG. 2A) and the side surface (e.g., the side surface (211c) of the electronic device (301) in FIG. 2A). In one embodiment, the case (390) may expose at least a portion of the components arranged on the outer surface of the electronic device (301) to the outside when the case (390) is mounted on the electronic device (301). For example, when the case (390) is mounted on the electronic device (301), the case (390) may cover only the back surface and the side surface of the electronic device (301) so that the display of the electronic device (301) is exposed to the outside.

[0077] In one embodiment, the case (390) may be formed in a shape and size corresponding to the shape of the corresponding electronic device (301) so that the case (390) may be easily mounted on the electronic device (301). For example, the shape and size of the case (390) may be determined corresponding to the corresponding electronic device (301). In one embodiment, the case (390) may include a base portion (391), a side portion (392), one or more through holes (393), and one or more reinforcing members (e.g., reinforcing members (595) of FIG. 5A).

[0078] In one embodiment, the base portion (391) may cover one side of the electronic device (301). For example, when the case (390) is mounted on the outer surface of the electronic device (301), the base portion (391) may be positioned to face the rear surface of the electronic device (301) and support the rear surface of the electronic device (301). In one embodiment, the base portion (391) may be formed to have a shape and size corresponding to the rear surface of the electronic device (301).

[0079] In one embodiment, the side portion (392) may cover the side of the electronic device (301). When the case (390) is mounted on the outer surface of the electronic device (301), the side portion (392) may surround the side of the electronic device (301) and support the side of the electronic device (301). In one embodiment, the side portion (392) may be formed to have a shape and size corresponding to the side of the electronic device (301). In one embodiment, the side portion (392) may be connected along the circumferential direction of the base portion (391) and may be formed to protrude in the height direction (e.g., +Z direction) from the base portion (391). In one embodiment, the height of the side portion (392) may be substantially the same along the circumference of the base portion (391). In one embodiment, the height of the side portion (392) may be formed to have a height corresponding to the side of the electronic device (301).

[0080] In one embodiment, the case (390) may form a mounting space (3901) in which the electronic device (301) may be mounted through the base portion (391) and the side portion (392). In one embodiment, the case (390) may be opened in a direction opposite to the base portion (391) (e.g., toward the front of the electronic device (301) facing the +Z direction). For example, when the case (390) is mounted on the outer surface of the electronic device (301), the display disposed on the front of the display may be visually exposed to the outside of the case (390). In one embodiment, although not illustrated in the drawing, the case (390) may further include a cover portion (not illustrated) that is rotatably connected to the side portion (392) and selectively covers the front of the electronic device (301).

[0081] In one embodiment, the case (390) may include one or more through holes (393) formed through the base portion (391) or the side portion (392). For example, the through holes (393) may include one or more first through holes (393) formed through the side portion (392). According to one embodiment, the through holes (393) may include one or more second through holes (394) formed through the base portion (391) (e.g., the second through holes (994) of FIG. 9A). In one embodiment, the through holes (393) may expose a portion of a component disposed on the side or back of the electronic device (301) to the outside of the case (390) when the case (390) is mounted on the electronic device (301). In one embodiment, each through hole (393) may be formed at a location in the case (390) corresponding to at least one component among the components exposed on the outer surface of the electronic device (301).

[0082] In one embodiment, one or more first through-holes (393) may correspond to components formed on the side surface of the electronic device (301), respectively. In one embodiment, when the case (390) is mounted on the outer surface of the electronic device (301), one or more first through-holes (393) may be formed in a portion of the case (390) that overlaps with a corresponding component formed on the side surface of the electronic device (301). For example, one or more first through-holes (393) may include a first through-hole (393-1) corresponding to a connection terminal (378) formed on the side of the electronic device (301) (e.g., a connection terminal (278) of FIG. 2A), a first through-hole (393-2) corresponding to a speaker hole (355) formed on the side of the electronic device (301) (e.g., an audio output module (155) of FIG. 1), a first through-hole (393-3) corresponding to a first input button (350-1) formed on the side of the electronic device (301) (e.g., an input module (250) of FIG. 2A), a first through-hole (393-4) corresponding to a second input button (350-2) formed on the side of the electronic device (301) (e.g., an input module (250) of FIG. 2A), and a microphone formed on the side of the electronic device (301). The case (390) may include first through-holes (393-5) corresponding to the holes (350-3) (e.g., the input module (250) of FIG. 2A). In one embodiment, each first through-hole (393) may expose components located on the side of the corresponding electronic device (301) to the outside of the case (390).

[0083] However, it should be noted that the number, arrangement, and shape of the first through-holes (393) described above are exemplary, and the number, arrangement, and shape of the through-holes (393) can be easily changed to correspond to components formed in the electronic device (301) corresponding to the case (390).

[0084] In one embodiment, the second through-hole (394) may be formed in a portion of the base portion (391) corresponding to a component formed on the rear of the electronic device (301), for example, a rear camera (e.g., the second camera module (280b) or the flash (280c) of FIG. 2B). For example, the second through-hole (394) may expose the rear camera disposed on the rear of the electronic device (301) to the outside of the case (390) when the case (390) is mounted on the electronic device (301). However, this is merely exemplary, and the number, arrangement, and shape of the second through-holes (394) formed on the case (390) are not limited. In addition, the case (390) may include only the first through-hole (393).

[0085] In one embodiment, a reinforcing member (e.g., reinforcing member (595) of FIG. 5A) may be embedded within the case (390). For example, each reinforcing member may be positioned in a portion of the case (390) corresponding to a through hole (393) formed in the case (390), and may reinforce the rigidity of the portion of the case (390) formed in the through hole (393). This will be described later.

[0086] Fig. 4a is a perspective view of a case (490) according to one embodiment. Fig. 4b is an enlarged view of area A of Fig. 4a to illustrate a through hole according to one embodiment. Fig. 4c is an enlarged view of area A of Fig. 4a to illustrate a through hole according to one embodiment.

[0087] Referring to FIGS. 4A, 4B, and 4C, a case (490) according to one embodiment (e.g., case (390) of FIG. 3) may include a base portion (491) (e.g., base portion (391) of FIG. 3), a side portion (492) (e.g., side portion (392) of FIG. 3), one or more through holes formed in the side portion (492) (e.g., first through hole (393) of FIG. 3A), and one or more reinforcing members (495) arranged in the side portion (492) to correspond to at least one of the through holes. In one embodiment, the base portion (491) may be formed in a plate shape. For example, the base portion (491) may be formed in a substantially rectangular plate shape corresponding to a shape of a rear surface of an electronic device (e.g., rear surface (310b) of the electronic device of FIG. 3). In one embodiment, the side portion (492) can extend from the base portion (491) along the perimeter of the base portion (491) in the height direction (H) (e.g., in the direction parallel to the +Z direction). For example, the side portion (492) can be formed to protrude in the height direction (H) from an edge of the base portion (491). The base portion (491) and the side portion (492) can form a mounting space (4901) in which an electronic device (e.g., the electronic device (101) of FIG. 1, the electronic device (201) of FIG. 2, and the electronic device (301) of FIG. 3) can be mounted.

[0088] In one embodiment, the one or more through holes may include one or more first through holes (493) formed in the side portion (492) and one or more second through holes (e.g., the second through holes (994) of FIG. 9b) formed in the base portion (491).

[0089] In one embodiment, one or more first through holes (493) may be formed through a side portion (492) of the case (490). Each first through hole (493) may penetrate through the side portion (492) of the case (490) to expose a portion of a side of an electronic device positioned in a mounting space (4901) (e.g., mounting space (3901) of FIG. 3) to the outside of the case (490). In one embodiment, a plurality of first through holes (493) may be formed at different locations of the side portion (492) of the case (490). Each first through hole (493) may be formed in a different size and shape depending on a component of the corresponding electronic device. For example, the through holes may include, but are not limited to, a 1-1 through hole (493-1) (e.g., the 1-1 through hole (393-1) of FIG. 3), a 1-2 through hole (493-2) (e.g., the 1-2 through hole (393-2) of FIG. 3), a 1-3 through hole (493-3) (e.g., the 1-3 through hole (393-3) of FIG. 3), a 1-4 through hole (493-4) (e.g., the 1-4 through hole (393-4) of FIG. 3), and a 1-5 through hole (493-5) (e.g., the 1-5 through hole (393-5) of FIG. 3), as illustrated in FIG. 4.

[0090] In one embodiment, the second through-hole may be formed through the base portion (491) of the case (490). The second through-hole may expose a portion of the rear surface of the electronic device to the outside of the case (490). For example, the second through-hole may be formed at a location of the base portion (491) corresponding to a rear camera of the electronic device (e.g., the second camera module (280b) of FIG. 2b), as illustrated in FIG. 4. In one embodiment, a plurality of second through-holes may be formed in the case (490), and may be formed at different locations of the base portion (491).

[0091] In one embodiment, one or more reinforcing members (495) may be disposed inside the side portion (492) or the base portion (491). For example, the reinforcing members (495) may not be visually exposed to the outside of the case (490). In one embodiment, one or more reinforcing members (495) may correspond to at least one through hole among a plurality of through holes formed in the case (490). Each reinforcing member (495) may be disposed at a portion of the side portion (492) where the corresponding through hole is formed, thereby reinforcing the rigidity of the side portion (492) where the corresponding through hole is formed. In one embodiment, one reinforcing member (495) may be disposed around at least one through hole among the plurality of through holes formed in the case (e.g., the first-first through hole (493-1)). In one embodiment, a plurality of reinforcing members (495) may be arranged around at least one of the plurality of through holes formed in the case (490) (e.g., the second through hole). In one embodiment, the reinforcing member (495) may not be arranged around at least one of the plurality of through holes formed in the case (490). For example, the reinforcing member (495) may be omitted in a portion of the side portion (492) where small through holes (e.g., 1-5 through holes) are formed.

[0092] In one embodiment, the reinforcing member (495) may be formed of a material having relatively high rigidity compared to the base portion (491) and the side portion (492). For example, the base portion (491) and the side portion (492) of the case (490) may include a first material, and the reinforcing member (495) may include a second material having higher rigidity than the first material. In one embodiment, the first material may be a flexible material that can be deformed, such as thermoplastic poly urethane (TPU), rubber, or silicone. In one embodiment, the base portion (491) and the side portion (492) may be formed of different materials. For example, the side portion (492) may be formed of the first material, and the base portion (491) may include a first-first material having relatively high rigidity compared to the first material, for example, a polycarbonate (PC) material. For example, when the case (490) is mounted on the electronic device, the side portion (492) may be formed of a flexible material so as to be in close contact with the side of the electronic device (e.g., the side portion (211c) of FIG. 2A), and the base portion (491) may be formed of a material that is relatively rigid compared to the side portion (492) so as to be able to absorb external pressure or impact applied to the rear of the electronic device.

[0093] In one embodiment, the second material forming the reinforcing member (495) may include, for example, at least one of a thermoplastic polymer material, a thermosetting polymer material, and a metal material. The second material is not limited thereto, and may include any material having greater rigidity than the first material, and a combination thereof.

[0094] In one embodiment, the reinforcing member (495) can reduce or prevent deformation of the case (490) by reinforcing the rigidity of the portion of the case (490) where the corresponding through-hole is formed. For example, the case (490) may receive an external force so as to be deformed during use. For example, the portion of the side portion (492) where the through-hole is formed may be subjected to compressive stress and be deformed relatively more significantly than the surrounding portions, and may be bent so as to deform the shape of the through-hole. The deformation of the portion of the side portion (492) where the through-hole is formed is not limited to temporary deformation due to the external force, and may include permanent deformation such as fatigue deformation due to repeated deformation. In one embodiment, the reinforcing member (495) is disposed inside the portion of the side portion (492) where the corresponding through-hole is formed, thereby reinforcing the rigidity of the portion of the side portion (492) where the through-hole is formed, and reducing or preventing temporary and permanent deformation of the shape of the side portion (492) where the through-hole is formed.

[0095] Hereinafter, for the convenience of explanation, the configuration of the corresponding through-hole and the reinforcing member (495) will be described through the 1-1 through-hole (493-1) formed in the side portion (492) and the reinforcing member (495) positioned adjacent to the 1-1 through-hole (493-1). However, it should be noted that the description below is not limited to the description of the 1-1 through-hole (493-1) and the corresponding reinforcing member (495), and can be equally applied to various through-holes and corresponding reinforcing members (495) that can be formed in the side portion (492) of the case (490) within a non-conflicting range.

[0096] In one embodiment, the case (490) may include one or more reinforcing members (495) positioned inside the side portion (492). In one embodiment, the reinforcing members (495) may be inserted into the inside of the side portion (492) to reinforce the rigidity of the side portion (492).

[0097] Fig. 5a is a partial perspective view of a side portion (592) of a case (490) in which a through hole (593) is formed according to one embodiment. Fig. 5b is a cross-sectional view of the side portion (592) along the CC line of Fig. 5a. Fig. 5c is a perspective view of the side portion (592) of a case (490) in which a through hole (593) is formed according to one embodiment, viewed in the height direction (H). Fig. 5d is a drawing for explaining the positional relationship between corresponding through holes (593) and reinforcing members (595) in a case (490) according to one embodiment.

[0098] Hereinafter, when describing exemplary structures of the through hole (593) and the reinforcing member (595), the abc coordinate system is used as a reference, which means that the structure and direction in which they are arranged in the case (490) of various embodiments are not limited to the XYZ coordinate direction and can be implemented in various ways. Referring to FIGS. 5A, 5B, 5C, and 5D, the reinforcing member (595) (e.g., the reinforcing member (495) of FIG. 4B) can be arranged inside the side portion (592) (e.g., the side portion (392) of FIG. 3, the side portion (492) of FIG. 4A) of the case (490) (e.g., the case (390) of FIG. 3, the case (490) of FIG. 4A). In one embodiment, the reinforcing member (595) may be positioned adjacent to a corresponding through hole (593) (e.g., the first through hole (393-1) of FIG. 3, the first through hole (493-1) of FIG. 4a).

[0099] In one embodiment, the reinforcing member (595) may include a second material having greater rigidity than the first material included in the side portion (592). For example, the second material may include at least one of a thermoplastic polymer material, a thermosetting polymer material, and a metallic material. The second material is not limited thereto, and may include any material having greater rigidity than the first material, and combinations thereof.

[0100] In one embodiment, the reinforcing member (595) can have a longitudinal direction (L) (e.g., parallel to the +a-axis direction). In one embodiment, the reinforcing member (595) can be arranged substantially parallel to the side portion (592). For example, at least a portion of the side portion (592) can extend substantially in a straight line along an edge of the base portion (591), and the reinforcing member (595) can have a longitudinal direction that is substantially parallel to the direction in which the corresponding side portion (592) extends. For example, the longitudinal direction (L) of the reinforcing member (595) can be parallel to the extension direction (e.g., parallel to the a-axis or parallel to the b-axis) of the corresponding side portion (592).

[0101] In one embodiment, the reinforcing member (595) may be positioned opposite the base portion (591) with the through hole (593) interposed therebetween, based on the height direction (H) of the side portion (592) (e.g., the height direction (H) of FIG. 4A and / or the direction parallel to the +c axis). For example, the through hole (593) may be positioned between the corresponding reinforcing member (595) and the base portion (591) with the height direction (H) as the reference. In one embodiment, the side portion (592) in which the through hole (593) is formed may include a first region (392-1) adjacent to the base portion (591) and a second region (392-2) opposite to the base portion (591) along the height direction (H). The first region (392-1) and the second region (392-2) of the side portion (592) can be distinguished with the through hole (593) interposed therebetween based on the height direction (H). For example, the first region (392-1) may refer to the side portion (592) formed between the base portion (591) and the through hole (593), and the second region (392-2) may refer to the side portion (592) located above (e.g., in the +C direction) the through hole (593). In one embodiment, when an external force is applied to the side portion (592), the second region (392-2) may be deformed to a relatively greater extent than the first region (392-1).

[0102] In one embodiment, the reinforcing member (595) may be placed in the second region (392-2) of the side portion (592) where the corresponding through hole (593) is formed. The reinforcing member (595) may be placed in the second region (392-2) to reinforce the rigidity of the second region (392-2), thereby reducing or preventing shape deformation and permanent deformation of the second region (392-2).

[0103] In one embodiment, when looking at the upper surface of the side portion (592) (e.g., when looking at the side portion (592) in the -c direction), the reinforcing member (595) may be positioned on the side portion (592) so as to overlap the corresponding through hole (593). For example, when looking at the side portion (592) in a direction parallel to the height direction (H), the corresponding reinforcing member (595) and the through hole (593) may at least partially overlap each other. In one embodiment, the reinforcing member (595) may reinforce the reduced stiffness of a portion of the side portion (592) where a void in the material is created by forming the through hole (593).

[0104] In one embodiment, the length in the longitudinal direction (L) of the reinforcing member (595) may be greater than the length in the longitudinal direction (L) (e.g., the axis parallel to the a-axis) of the corresponding through hole (593). For example, by forming the length in the longitudinal direction (L) of the reinforcing member (595) to be greater than the length in the longitudinal direction (L) of the corresponding through hole (593), the reinforcing member (595) may reinforce the rigidity of the side portion (592) (e.g., the second region (392-2)) that is vulnerable to bending deformation by the corresponding through hole (593). For example, the rigidity may be reinforced by the corresponding reinforcing member (595) up to the region of the side portion (592) located at both ends in the longitudinal direction of the through hole (593).

[0105] In one embodiment, when looking at the upper surface of the side portion (592) (e.g., when looking at the side portion (592) in the -c direction), the range area in the longitudinal direction (L) formed by the through hole (593) may be located within the range area formed in the longitudinal direction (L) by the corresponding reinforcing member (595). For example, when looking at the upper surface of the side portion (592) in a direction parallel to the height direction (H) (e.g., when looking at the -c direction), the range area in the longitudinal direction (L) formed by the through hole (593) may overlap the range area formed in the longitudinal direction (L) by the reinforcing member (595). For example, when looking at the upper surface of the side portion (592) in a direction parallel to the height direction (H) (e.g., when looking at the -c direction), the length of the range area in the longitudinal direction (L) formed by the through hole (593) may be less than or equal to the length of the range area formed in the longitudinal direction (L) by the corresponding reinforcing member (595).

[0106] In one embodiment, the reinforcing member (595) may be configured to have a shape in which a width (W) perpendicular to the height direction (H) is greater than a height (T) in the height direction (H), based on a cross-section (e.g., a longitudinal section) of the reinforcing member (595) perpendicular to the longitudinal direction (L). For example, the reinforcing member (595) may be configured to have a width (W) perpendicular to the height direction (H) greater than a height (T) in the height direction (H), thereby reinforcing bending rigidity in the direction perpendicular to the height direction (H). In FIG. 5b, the shape of the cross-section perpendicular to the longitudinal direction (L) of the reinforcing member (595) is illustrated as a rectangle, but is not limited thereto and may be formed as a circle, an ellipse, or a polygon.

[0107] In one embodiment, the reinforcing member (595) may include a bar portion (5951) extending in the longitudinal direction (L), and support portions (5952a, 5952b) each connected to an end of the bar portion (5951).

[0108] In one embodiment, the bar portion (5951) may be positioned inside the side portion (592) to reinforce the rigidity of the side portion (592). In one embodiment, the bar portion (5951) may be formed in the shape of a bar extending in the longitudinal direction (L). For example, the bar portion (5951) may extend between the first end and the second end.

[0109] In one embodiment, the support portions (5952a, 5952b) can support the reinforcing member (595) to fix it so as to reduce or prevent flow with respect to the side portion (592) of the reinforcing member (595). For example, the support portions (5952a, 5952b) can be formed to engage with the side portion (592) to fix it so as to support it. In one embodiment, when the side portion (592) is manufactured by injection molding with respect to the base portion (591), the support portions (5952a, 5952b) can support the reinforcing member (595) to fix it so as to prevent flow within the mold while the side portion (592) is injected. In one embodiment, when the case (490) is detached or the side portion (592) is deformed, the support portions (5952a, 5952b) can support the reinforcement member (595) to secure the reinforcement member (595) to the side portion (592) to reduce or prevent movement of the reinforcement member (595) within the side portion (592). In one embodiment, the support portions (5952a, 5952b) can include a first support portion (5952a) connected to the first end, and a second support portion (5952b) connected to the second end. In one embodiment, the first support portion (5952a) can have a first support groove (5952a-1) formed inwardly toward the center of the first support portion (5952a). In one embodiment, the second support portion (5952b) may be formed with a second support groove (5952b-1) that is concave inward toward the center of the second support portion (5952b). For example, the first support groove (5952a-1) and the second support groove (5952b-1) may be formed concave in different directions. For example, the first support groove (5952a-1) and the second support groove (5952b-1) may be formed concave in directions perpendicular to each other. For example, the first support groove (5952a-1) may be concave in a first direction parallel to the height direction (H).For example, the second support groove (5952b-1) may be concave in a second direction perpendicular to the first direction.

[0110] In one embodiment, when the reinforcing member (595) is viewed in the height direction (H), the through hole (593) corresponding to the reinforcing member (595) may be located between the first support portion (5952a) and the second support portion (5952b). For example, the through hole (593) may be formed in an area that does not exceed the first end and the second end of the reinforcing member (595).

[0111] Fig. 6 is a perspective view of a reinforcing member (695) according to one embodiment. Fig. 7 is a perspective view of a reinforcing member (695) according to one embodiment. Fig. 8 is a perspective view of a reinforcing member (695) according to one embodiment.

[0112] Hereinafter, any overlapping content with the above-described content will be omitted for explanation, and in a case (e.g., case (390) of FIG. 3, case (490) of FIG. 4a), it should be noted that some configurations and structures of the reinforcing member (695) may be replaced, added, or omitted within a range that can be easily understood by those skilled in the art by referring to the drawings and descriptions below. In one embodiment, the description of the reinforcing member (695) described above may be equally applied to the embodiments below, unless otherwise specifically stated.

[0113] Referring to FIG. 6, in one embodiment, a reinforcing member (695) (e.g., reinforcing member (495) of FIG. 4b, reinforcing member (595) of FIG. 5a) includes a bar portion (6951) (e.g., bar portion (5951) of FIG. 5a) extending in a longitudinal direction (L) (e.g., longitudinal direction (L) of FIG. 5a, direction parallel to the +a axis), a first support portion (6952a) (e.g., first support portion (5952a) of FIG. 5d) connected to a first end of the bar portion (6951) and having a first support groove (6952a-1) (e.g., first support groove (5952a-1) of FIG. 5d) formed therein, a second support groove (6952b-1) (e.g., first support groove (6952a-1) of FIG. 5d) connected to a second end of the bar portion (6951) and formed in a different direction from the first support groove (6952a-1). A second support portion (6952b) (e.g., the second support portion (5952b) of FIG. 5d) in which a second support groove (5952b-1) is formed may be included. For example, the first support groove (6952a-1) may be concave in a first direction parallel to the height direction (H). For example, the second support groove (6952b-1) may be concave in a second direction perpendicular to the first direction. In one embodiment, the first support groove (6952a-1) may be formed such that the first support groove (6952a-1) has a gradient in the concave direction. The second support groove (6952b-1) may be formed such that the second support groove (6952b-1) has a gradient in the concave direction. The slope of the first support groove (6952a-1) and / or the second support groove (6952b-1) can reduce or prevent movement of the reinforcing member (695) during the manufacturing process in which the reinforcing member (695) is placed inside the case (490).

[0114] In one embodiment, the first support groove (6952a-1) and the second support groove (6952b-1) may be formed such that the width on the outside of the support portion (6952a, 6952b) is smaller than the width on the inside of the support portion (6952a, 6952b). In one embodiment, the support portion (6952a, 6952b) may have a cross-sectional shape such that the first width (W1) of the support groove (6952a-1, 6952b-1) on the outside of the support portion (6952a, 6952b) is smaller than the second width (W2) of the support groove (6952a-1, 6952b-1) on the inside of the support portion (6952a, 6952b). For example, the width of the support grooves (6952a-1, 6952b-1) may have a cross-sectional shape that continuously decreases between the first width (W1) and the second width (W2). For example, the width of the support grooves (6952a-1, 6952b-1) may have a cross-sectional shape that discontinuously decreases between the first width (W1) and the second width (W2).

[0115] Referring to FIG. 7, the reinforcing member (795) (e.g., reinforcing member (495) of FIG. 4b, reinforcing member (595) of FIG. 5a, reinforcing member (695) of FIG. 6) may include a bar portion (7951) (e.g., bar portion (5951) of FIG. 5a, bar portion (6951) of FIG. 6), a first support portion (7952a) (e.g., first support portion (5952a) of FIG. 5a, first support portion (6952a) of FIG. 6), and a second support portion (7952b) (e.g., second support portion (5952b) of FIG. 5a, second support portion (6952b) of FIG. 6).

[0116] In various embodiments of the present document, the description of the bar portion (7951), the first support portion (7952a), and the second support portion (7952b) of the above-described reinforcing member (795) may be applied identically or similarly to the bar portion (7951), the first support portion (7952a), and the second support portion (7952b) of the reinforcing member (795), unless otherwise specifically stated.

[0117] In one embodiment, the reinforcing member (795) may have a constant cross-sectional size along the longitudinal direction (L) (e.g., the longitudinal direction (L) of FIG. 5a, the longitudinal direction (L) of FIG. 6, the direction parallel to the +a axis). In one embodiment, the reinforcing member (795) may be formed so that the cross-sectional size changes along the longitudinal direction (L). For example, the bar portion (7951) may be formed so that the cross-sectional size continuously changes along the longitudinal direction (L). For example, the reinforcing member (795) may be formed so that the central portion has a larger cross-sectional area than the end portions based on the cross-section perpendicular to the longitudinal direction (L). For example, the central portion of the reinforcing member (795) may have a larger cross-sectional area than the end portions, thereby having relatively higher flexural rigidity than the end portions.

[0118] In one embodiment, the spacing between the reinforcing member (795) and the corresponding through hole (e.g., the first through hole (393) of FIG. 3, the first through hole (493) of FIG. 4A, the through hole (493) of FIG. 5) may be substantially constant. For example, the reinforcing member (795) may be formed and / or positioned to correspond to the shape of the corresponding through hole, thereby reinforcing the side portion (792) adjacent to the through hole.

[0119] Referring to FIG. 8, the reinforcing member (895) (e.g., reinforcing member (495) of FIG. 4b, reinforcing member (595) of FIG. 5a, reinforcing member (695) of FIG. 6, reinforcing member (765) of FIG. 7) may include a bar portion (8951) (e.g., bar portion (5951) of FIG. 5a, bar portion (6951) of FIG. 6, bar portion (7951) of FIG. 7), a first support portion (8952a) (e.g., first support portion (5952a) of FIG. 5a, first support portion (6952a) of FIG. 6, first support portion (7952a) of FIG. 7), and a second support portion (8952b) (e.g., second support portion (5952b) of FIG. 5a, second support portion (6952b) of FIG. 6, second support portion (7952b) of FIG. 7).

[0120] In various embodiments of the present document, the description of the bar portion (8951), the first support portion (8952a), and the second support portion (8952b) of the above-described reinforcing member (895) may be applied identically or similarly to the bar portion (8951), the first support portion (8952a), and the second support portion (8952b) of the reinforcing member (895), unless specifically stated otherwise.

[0121] In one embodiment, the first support portion (8952a) and the second support portion (8952b) may each have a through hole (8952a-1, 8952b-1) formed in the center thereof (e.g., support grooves (5952a-1, 5952b-1) of FIG. 5d , support grooves (6952a-1, 6952b-1) of FIG. 6 , and support grooves (7952a-1, 7952b-1) of FIG. 7 ). For example, the through holes formed in the centers of the first support portion (8952a) and the second support portion (8952b) may have a shape such as a circle, an oval, or a polygon. In one embodiment, each of the through holes of the first support portion (8952a) and the second support portion (8952b) may be engaged with an anchoring structure inside the side portion (892).

[0122] In one embodiment, during a process of manufacturing a case (e.g., case (390) of FIG. 3, case (490) of FIG. 4a), for example, during a process of injecting the case within a mold, the reinforcing member (895) may be mounted to the mold through a through-hole formed in the first support portion (8952a) and the second support portion (8952b). In other words, the first support portion (8952a) and the second support portion (8952b) are fixed to a mold portion where a side portion (892) (e.g., side portion (392) of FIG. 3, side portion (492) of FIG. 4a, side portion (492) of FIG. 5a) is formed through the through-hole, thereby reducing or preventing a flow phenomenon of the reinforcing member (895) that occurs when injecting the case (490) within the mold.

[0123] Fig. 9a is a perspective view of a case (990) according to one embodiment. Fig. 9b is an enlarged view of area B of Fig. 9a to illustrate through holes (993, 994) according to one embodiment.

[0124] Hereinafter, the overlapping contents with the above-described contents will be omitted and explained, and in the case (990 (e.g., case (390) of FIG. 3, case (490) of FIG. 4a), some configurations and structures may be replaced, added, or omitted within a range that can be easily understood by those skilled in the art with reference to the drawings and descriptions below. In addition, in the case (990), at least one configuration or feature of the embodiments described above may be combined unless it is technically clearly impossible.

[0125] Referring to FIGS. 9A and 9B , the case (990) may include a base portion (991) (e.g., the base portion (391) of FIG. 3 , the base portion (491) of FIG. 4A , and the base portion (591) of FIG. 5A ), a side portion (992) (e.g., the side portion (392) of FIG. 3 , the side portion (492) of FIG. 4A , and the side portion (492) of FIG. 5A ), one or more through holes (993, 994) (e.g., the through holes (393, 394) of FIG. 3 ), and one or more reinforcing members (995) (e.g., the reinforcing members (495) of FIG. 4B , the reinforcing members (595) of FIG. 5A , the reinforcing members (695) of FIG. 6 , the reinforcing members (795) of FIG. 7 , and the reinforcing members (895) of FIG. 8 ).

[0126] In one embodiment, the through-hole may include one or more first through-holes (993) formed in the side portion (992) (e.g., the first through-hole (393) of FIG. 3, the first through-hole (493) of FIG. 4a, the through-hole (493) of FIG. 5) and one or more second through-holes (994) formed in the base portion (991). In one embodiment, the reinforcing member (995) may include one or more first reinforcing members (e.g., the first reinforcing member (495) of FIG. 4b) disposed in the side portion (992) corresponding to the first through-holes (993) and one or more second reinforcing members (995) disposed in the base portion (991) corresponding to the second through-holes (994). The first reinforcing member is embedded within the side portion (992), and the second reinforcing member (995) is embedded within the base portion (991), so that they may not be directly exposed to the outside of the case (990).

[0127] In describing the case (990) according to FIGS. 9a and 9b, the first reinforcing member may have substantially the same configuration as the reinforcing members of FIGS. 5a, 5b, 5c and 5d, and the description of the first reinforcing member is to be applied to the contents described through FIGS. 5a, 5b, 5c and 5d to the extent that they do not conflict with the case (990) according to FIGS. 9a and 9b.

[0128] In one embodiment, the second reinforcing member (995) may be disposed on the base portion (991) adjacent to the second through hole (994). The second reinforcing member (995) may reinforce the rigidity of the portion of the base portion (991) where the second through hole (994) is formed. In one embodiment, a plurality of second reinforcing members (995) may be disposed around the base portion (991) where the second through hole (994) is formed. For example, as illustrated in FIG. 9B, four second reinforcing members (995) may be disposed on the base portion (991) so as to surround the circumference of the second through hole (994). According to one embodiment, the second reinforcing member (995) may be formed as a single member and may be disposed on the base portion (991) so as to surround the circumference of the second through hole (994). However, the above-described example is only one embodiment, and the number and arrangement of the second reinforcing members (995) provided in the case (990) may be changed in accordance with the shape and arrangement of the second through hole (994).

[0129] In one embodiment, the second reinforcing member (995) can reinforce the rigidity of the base portion (991) adjacent to the second through hole (994). For example, the second reinforcing member (995) can reduce or prevent deformation of the base portion (991) due to an external force applied to the base portion (991) during the process of attaching or detaching the case (990) to the electronic device, or during the process of use.

[0130] A case (390; 490; 990) to be mounted on an outer surface of an electronic device (101; 201; 301) according to one embodiment comprises: a base portion (391; 491; 591; 991), a side portion (392; 492; 592; 992) extending in a height direction (H) from the base portion (391; 491; 591; 991) along a perimeter of the base portion (391; 491; 591; 991), in which one or more through holes (394; 493; 593; 993) are formed; and one or more reinforcements disposed inside the side portion (392; 492; 592; 992) so as to be adjacent to at least one of the through holes (393; 493; 593; 993) and extending along a length direction (L). It may include reinforcing members (395;495;595;695;795;895). In one embodiment, the reinforcing members (395;495;595;695;795;895;995) may reinforce the rigidity of the side portions (392;492;592;992) in which the corresponding through holes (393;493;593;993) are formed.

[0131] In one embodiment, based on the height direction (H) of the side portions (392;492;592;992), the reinforcing members (395;495;595;695;795;895) may be positioned opposite the base portions (391;491;591;991) with the through holes (393;493;593;993) therebetween.

[0132] In one embodiment, when the side portions (392; 492; 592; 992) are viewed in the height direction (H), the through holes (393; 493; 593; 993) can overlap the corresponding reinforcing members (395; 495; 595; 695; 795; 895).

[0133] In one embodiment, the length (L1) of the reinforcing member (395; 495; 595; 695; 795; 895) in the longitudinal direction (L) may be greater than the length parallel to the longitudinal direction (L2) of the corresponding through hole (393; 493; 593; 993).

[0134] In one embodiment, when viewed in the height direction (H), the range area in the longitudinal direction (L) formed by the through holes (393; 493; 593; 993) may be located within the range area formed in the longitudinal direction (L) by the corresponding reinforcing members (395; 495; 595; 695; 795; 895).

[0135] In one embodiment, the reinforcing member (395; 495; 595; 695; 795; 895) may be configured to have a shape in which a width (W) perpendicular to the height direction (H) is greater than a height (T) in the height direction, based on a cross-section of the reinforcing member (395; 495; 595; 695; 795; 895) perpendicular to the length direction (L).
