     TECHNICAL FIELD 
     Various embodiments of the disclosure relate to an electronic device, and more particularly, an accessory and/or an electronic device including the accessory. 
     BACKGROUND ART 
     An electronic device refers to a device that performs a specific function according to a loaded program, such as a home appliance, an electronic notebook, a portable multimedia player, a mobile communication terminal, a tablet PC, a video/audio device, a desktop/laptop computer, or a vehicle navigation device. For example, these electronic devices may output stored information as sound or an image. As the integration level of electronic devices increases, and high-speed and large-capacity wireless communication becomes common, a single electronic device such as a mobile communication terminal may be equipped with various functions. For example, an entertainment function such as games, a multimedia function such as music/video playback, a communication and security function for mobile banking, and/or scheduling or an electronic wallet function as well as a communication function are integrated into one electronic device. 
     As electronic devices such as mobile communication terminals and smartphones have become popular, the electronic devices are treated as one of daily necessities. For such electronic devices, various types of accessories have been released in the aftermarket, and accessories may be used to add functions of the electronic devices and improve the performance, portability, and use convenience of the electronic devices. In the aftermarket, for example, a protective case provides a space for holding a card therein, beyond a simple protection function, thus making it convenient to carry belongings. A cradle in a living space, inside a vehicle, or in leisure activities may allow a user to freely take activities while using an electronic device. An auxiliary battery supplements the limited power capacity of the electronic device, and/or an accessory that may be coupled/combined with a smartphone such as a simple point of sales (POS) terminal may contribute to increasing the work efficiency of a designated field of work. 
     The above information is presented as background information only to assist with an understanding of the disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the disclosure. 
     DISCLOSURE 
     Technical Problem 
     Accessories enabling protection, improved usability, and/or expansion of functions or performance together may be desired. For example, although an accessory that combines a protective case with a holding function or a card storage function is commercially available, it may be difficult to mount the electronic device in a state where the accessory is coupled with an electronic device on an in-vehicle cradle or couple the electronic device to a simple point of sales (POS) terminal. 
     Various embodiments of the disclosure are to address at least the above-mentioned problems and/or disadvantages and to provide at least the advantages described below. Accordingly, various embodiments of the disclosure may provide an accessory which enables storage of a belonging (e.g., a credit card or an identification (ID) card), while protecting an electronic device, and which is available as a storage medium, a card reader, and/or an auxiliary power source, and/or an electronic device including the accessory. 
     Various embodiments of the disclosure may provide an accessory available as a flat cradle or a wall mount holder to improve use convenience of an electronic device, and/or an electronic device including the accessory. 
     Additional aspects according to various embodiments will be presented through the detailed description set forth below, and may be apparent in part from the description or understood from the presented embodiments of the implementation.

In such embodiments, the support includes a fixing member coupled with the coupler, a hinge member coupled with the fixing member, where the hinge member rotates around a first rotation axis with respect to the fixing member, a first support member coupled with the hinge member, where the first support member pivots around the first rotation axis along with a rotation of the hinge member, and rotates around a second rotation axis intersecting with the first rotation axis with respect to the hinge member, and a second support member extending from an end of the first support member, where the second support member revolves around the first rotation axis along with a pivoting of the first support member, and pivots around the second rotation axis along with a rotation of the first support member. 
     According to various embodiments of the disclosure, an electronic device includes a body and an accessory detachably attachable to the body. In such embodiments, the accessory includes a coupler detachably attachable to at least one surface of the body, and a support coupled with the coupler to be pivotable between a first position at which the support contacts one surface of the coupler and a second position at which the support is inclined to the one surface of the coupler. In such embodiments, the support includes a fixing member coupled with the coupler, a hinge member coupled with the fixing member, where the hinge member rotates around a first rotation axis with respect to the fixing member, a first support member coupled with the hinge member, where the first support member pivots around the first rotation axis along with a rotation of the hinge member, and rotates around a second rotation axis intersecting with the first rotation axis with respect to the hinge member, and a second support member extending from an end of the first support member, where the second support member revolves around the first rotation axis along with the a pivoting of the first support member, and pivots around the second rotation axis along with a rotation of the first support member. 
     Advantageous Effects 
     According to various embodiments of the disclosure, as an accessory rotates (or pivots) at least a part of a support around two axes, the accessory may position the support to be inclined to a body or coupler of an electronic device in various angular directions. For example, the accessory may hold the electronic device in various directions or at various inclination angles with respect to a plane, thereby increasing use convenience. In an embodiment, the accessory may be used as a wall-mounted holder according to the rotation position of the support with respect to the coupler, so that the electronic device may be conveniently held in a typical living space or inside a vehicle. In a certain embodiment, because a storage space, a storage medium, an integrated circuit (IC) chip reader, a battery, or various communication antennas are disposed in an area or space surrounded by the support on one surface of the coupler, the accessory may be electrically coupled to the body of the electronic device, which is useful for function extension of the electronic device. Besides the above effect, the disclosure may provide various other effects which are directly or indirectly identified.

       FIG.  1    is an exploded perspective view illustrating an accessory  100  according to various embodiments of the disclosure.  FIG.  2    is a perspective view illustrating the accessory  100  according to various embodiments of the disclosure. 
     Referring to  FIGS.  1  and  2   , the accessory  100  may be configured as (or defined by) a part of an electronic device (e.g., an electronic device  1  of  FIG.  12   ) or may be configured to be detachably attached to a body (e.g., a body  10  of  FIGS.  7  and  8   , and/or  FIGS.  12 ,  13  and  14   ). For example, the accessory  100  may include a coupler  101   configured to be detachably attached to the body  10 , and a support  102  rotatably coupled with the coupler  101 . The support  102  may be rotatable, for example, between a first position (e.g., a state illustrated in  FIG.  6    or a first position P 1  of  FIG.  7   ) at which the support  102  contacts or closely contacts one surface of the coupler  101  and a second position at which the support  102  is inclined to the one surface of the coupler  101 . In an embodiment, the “second position” may be any of positions indicated by “P 2 - n ” in  FIG.  7    or “P 3 - n ” in  FIG.  8   , or any of states illustrated in  FIGS.  2 ,  12 , and  13   , where “n” is 1, 2 or 3. Depending on a rotation (or pivoting) position of the support  102  with respect to the coupler  101 , the accessory  100  may position the electronic device  1  or the body  10  of the electronic device  1  to be inclined to a plane, e.g., a planar surface that supports the electronic device  1  or the body  10  of the electronic device  1 , or may be used as a wall-mounted holder. For example, when the support  102  is at a position indicated by “P 2 - 3 ” of  FIG.  7    or “P 3 - 3 ” of  FIG.  8   , the support  102  may function as a wall-mounted holder. 
     According to various embodiments, the coupler  101  may be configured to be coupled with at least one surface of the electronic device  1  or at least one surface of the body  10 . For example, the coupler  101  may include a plate-shaped coupling member  111  corresponding to the one surface of the electronic device  1  or the body  10 , and may be coupled with the electronic device  1  in one of various manners, e.g., an adhesive or adsorption manner. The accessory  100  is selectively coupled or decoupled with the electronic device  1  or the body  10  by a user. Even though the electronic device  1  or the body  10  is not coupled with the accessory  100 , the electronic device  1  or the body  10  may perform functions loaded therein. When the accessory  100  is coupled with the electronic device  1  or the body  10 , a function provided by the accessory  100  may be used to increase the use convenience or performance of the electronic device  1  or the body  10  or extend functions of the electronic device  1  or the body  10 . The afore-mentioned “one surface of the coupler  101  coupled with the support 102” may be understood as substantially one surface of the coupling member  111 . 
     According to various embodiments, as shown in  FIGS.  1  and  2   , the coupling member  111  may be shaped into a plate, but various embodiments of the disclosure are not limited thereto, and the coupler  101  may be a structure coupled with the electronic device  1  or the body  10  by means of a hook or a rib extending from an edge of the coupling member  111 , surrounding side surfaces of the electronic device  1  or the body  10 . In embodiments where the coupler  101  is a the structure coupled with the electronic device  1  or the body  10 , surrounding the side surfaces of the electronic device  1  or the body  10 , the coupler  101  may be easily coupled with the electronic device  1  or the body  10  even without including an adhesive structure or an adsorption structure. 
     According to various embodiments, the accessory  100  or the coupler  101  may include an opening area  117  defined at least in part by the coupling member  111 . In an embodiment, the electronic device  1  or the body  10  may include a camera (e.g., a camera module  19  of  FIGS.  12 ,  13  and  14   ) disposed on the surface with which the accessory  100  is coupled, or a speaker hole (not shown). For example, when the accessory  100  is coupled with the electronic device  1  or the body  10 , the opening area  117  may disposed in correspondence with the camera or the speaker hole, to prevent an operating environment of the electronic device  1  or the body  10  from being disturbed. 
     According to various embodiments, the coupler  101  may further include a protrusion member  113  protruding from one surface of the coupling member  111 . In various embodiments, the coupling member  111  may be disposed between the protrusion member  113  and the electronic device  1  or the body  10  in a state where the coupler  101  is coupled with the electronic device  1  or the body  10 . The protrusion member  113  may be disposed, for example, in an area or space at least partially surrounded by the support  102  at the first position P 1  (i.e., the first position P 1  of  FIG.  7   ). For example, the support  102  may be disposed, at the first position P 1 , to surround at least a part of side surface(s) of the protrusion member  113 . In a certain embodiment, the side surface of the protrusion member  113  may be formed in the shape of a groove to receive at least a part of the support  102 , such that the support  102  may be fastened, at the first position P 1 , with the side surface of the protrusion member  113 . For example, the support  102  may be stably maintained in close contact with the coupler  101  in a portable state (i.e., a state where the support  102  is at the first position P 1 ). As described later, various electrical/electronic components (e.g., an electrical/electronic component  419  of  FIG.  11   ) may be accommodated or disposed in the protrusion member  113 , and the accessory  100  may improve the electrical/electronic performance of the electronic device  1  or the body  10  or diversify functions of the electronic device  1  or the body  10  according to the electrical/electronic component accommodated in the protrusion member  113 . In a certain embodiment, the protrusion member  113  may be substantially omitted. In such an embodiment, the support  102  may be directly coupled with one surface of the coupling member  111 , and at the first position P 1 , come into close contact with the surface of the coupling member  111 . In such an embodiment, the accessory  100  may improve the electrical/electronic performance of the electronic device  1  or the body  10  or diversify functions of the electronic device  1  or the body  10  even without the protrusion member  113  because various electrical/electronic components may be embedded in the coupling member  113 . 
     According to various embodiments, in the portable state, the support  102  may be located at the first position P 1 , for example, in contact with one surface of the coupler  101 , and selectively pivot with respect to the coupler  101  by the user, to hold the electronic device  1  or body  10  inclined to a plane. The configuration of the support  102  will be described with further reference to  FIGS.  3  to  6   . 
       FIG.  3    is a plan view illustrating the support  102  of the accessory  100  according to various embodiments of the disclosure.  FIG.  4    is a plan view illustrating the accessory  100  according to various embodiments of the disclosure.  FIG.  5    is a cross-sectional plan view illustrating a part of the accessory  100  according to various embodiments of the disclosure.  FIG.  6    is a side view illustrating the accessory  100  according to various embodiments of the disclosure. 
     Further referring to  FIGS.  3  to  6   , an embodiment of the support  102  may include a fixing member  121 , a hinge member  123 , and/or a plurality of support members  125 ,  127 , and  129 . The fixing member  121  is a component coupled with or fixed to the coupler  101 , and may be, for example, at least partially accommodated in the protrusion member  113 . In an embodiment, a first slot  115  (shown in  FIG.  1   ) may be provided on one side surface of the protrusion member  113 , and the fixing member  121  may be at least partially accommodated in the first slot  115 . According to another embodiment, the fixing member  121  may be substantially fixed to the first slot  115  or the protrusion member  113  by a snap-fit structure or a magnet, and separated from the first slot  115  when a force equal to or greater than a specified magnitude is applied thereto. In a certain embodiment having a structure in which the coupler  101  does not include the protrusion member  113 , the fixing member  121  may be directly coupled with one surface of the coupling member  111 . For example, the fixing member  121  may be substantially fastened with the coupling member  111  by a snap-fit structure or a magnet, while facing at least a part of one surface of the coupling member  111 . 
     In the following detailed description, when it is said that A ‘rotates (or is rotating)’, this may be understood as an operation in which A rotates around a rotation axis disposed to directly intersect with A or substantially pass through A, for example, as a concept similar to the rotation of the Earth. In the following detailed description, when it is said that A ‘revolves or revolves around’, this may be understood as an operation in which A moves along a curved or circular trajectory around a rotation axis or a pivoting axis at a position spaced apart from the rotation axis or the pivoting axis, for example, as a concept similar to the revolution of the Earth around the sun. In the following detailed description, when it is said that A “pivots”, this may be understood as an operation in which A being in the form of a cantilever such as a bar or a rod rotates round a rotation axis or a pivoting axis, while obliquely or perpendicularly intersecting with the rotation axis or the pivoting axis at one end thereof or at a point adjacent to one end thereof. For example, the pivoting may be understood as an operation in which a cantilever rotates around the sun, on the assumption that the cantilever connects the earth to the sun. 
     According to various embodiments, the hinge member  123  may be coupled with the fixing member  121 , and configured to rotate around a first rotation axis A 1  with respect to the fixing member  121 . In an embodiment, as shown in  FIG.  5   , the hinge member  123  may be coupled with the fixing member  121  through a first hinge module  123   a  and rotate around the first rotation axis A 1  with respect to the fixing member  121  or the first hinge module  123   a . In an embodiment, as the first hinge module  123   a  provides a static friction force of a specified magnitude, while allowing the hinge member  123  to rotate freely with respect to the fixing member  121 , the support  102  (e.g., a first support member  125  among the support members  125 ,  127 , and  129 ) may be maintained in a stationary state, inclined to the coupler  101 . 
     According to various embodiments, among the support members  125 ,  127 , and  129 , the first support member  125  may be shaped into a bar or rod extending in one direction (e.g., the direction of a second rotation axis A 2 ), have one end coupled with the hinge member  123 , and be configured to pivot around the first rotation axis A 1  along with rotation of the hinge member  123  around the first rotation axis A 1 . In an embodiment, the first support member  125  may be substantially disposed on the second rotation axis A 2 , extending in the direction of the second rotation axis A 2 , and configured to rotate around the second rotation axis A 2  with respect to the hinge member  123 . In a certain embodiment, as shown in  FIG.  5   , the first support member  125  may be coupled with the hinge member  123  through a second hinge module  123   b , and rotate around the second rotation axis A 2  with respect to the hinge member  123  or the second hinge module  123   b . As the second hinge module  123   b  provides a static friction force of a specified magnitude, while allowing the first support member  125  to freely rotate with respect to the hinge member  123 , the support  102  (e.g., a second support member  127  described later as one of the support members  125 ,  127 , and  129 ) may be maintained in the stationary state, inclined to the coupler  101 . 
     According to various embodiments, among the support members  125 ,  127 , and  129 , the second support member  127  may be shaped into a bar or rod extending in one direction (e.g., a direction of the first rotation axis A 1 ) from one end of the first support member, have one end coupled to the first support member  125 , and be configured to pivot around the second rotation axis A 2  along with rotation of the first support member  125  around the second rotation axis A 2 . In an embodiment, the second support member  127  may be disposed at a position substantially spaced apart from the first rotation axis A 1  by the length of the first support member  125  in a direction of the second rotation axis A 2 . For example, the second support member  127  may be configured to revolve around the first rotation axis A 1  along a curved or circular trajectory at the position spaced apart from the first rotation axis A 1 , along with rotation of the hinge member  123  around the first rotation axis A 1  or along with pivoting of the first support member  125  around the first rotation axis A 1 . 
     According to various embodiments, the accessory  100  may further include a third support member  129  provided as another one of the support members  125 ,  127  and  129 . The third support member  129  may extend, for example, from an end of the second support member  127  and be disposed parallel to or substantially parallel to the first support member  125 . For example, the third support member  129  may extend in a direction substantially perpendicular to the second support member  127 . In such an embodiment, where the third support member  129  is included, the support  102  (e.g., the support members  125 ,  127  and  129 ) may be substantially ‘U’-shaped. In an embodiment, the third support member  129  may be configured to revolve around the first rotation axis A 1 , when the hinge member  123  rotates. In another embodiment, the third support member  129  may be configured to revolve around the second rotation axis A 2 , when the first support member  125  rotates or when the second support member  127  pivots around the second rotation axis A 2 . 
     According to various embodiments, the first rotation axis A 1  and the second rotation axis A 2  may intersect with each other substantially perpendicularly, and the second support member  127  may extend in a direction perpendicular to the first support member  125  or the second rotation axis A 2 . At the first position P 1 , the first support member  125  and/or the second support member  127  may be located substantially in contact with one surface of the coupler  101  or in contact with different parts of the side surfaces of the protrusion member  113 . At the first position P 1 , the second support member  125  may be disposed substantially parallel to the first rotation axis A 1 . In a certain embodiment, the third support member  129  may extend in a direction parallel to the first support member  125  or the second rotation axis A 2  and be disposed parallel to the first support member  125 . At the first position P 1 , the third support member  129  may be located substantially in contact with one surface of the coupler  101  or in contact with another part of the side surfaces of the protrusion member  113 . 
       FIG.  7    is a diagram illustrating rotation of a part of the support  102  around the first rotation axis A 1  in the accessory  100  according to various embodiments of the disclosure. 
     In  FIG.  7   , for example, the hinge member  123  is shown as rotating around the first rotation axis A 1  with the support  102  (e.g., the first support member  125  and/or the second support member  127 ) without rotating or pivoting around the second rotation axis A 2 , from a state in which the support  102  is disposed at the first position P 1 . As the hinge member  123  rotates around the first rotation axis A 1 , the first support member  125  may pivot around the first rotation axis A 1 , and the second support member  127  and the third support member  129  may revolve around the first rotation axis A 1 . In a certain embodiment, where an end of the third support member  129  is located substantially on the first rotation axis A 1 , when the hinge member  123  rotates around the first rotation axis A 1 , the third support member  129  may be viewed as pivoting around the first rotation axis A 1 . 
     Referring to  FIG.  7   , ‘P 1 ’ may denote a first position at which the support  102  is in contact with the coupler  101 , and ‘P 2 - n ’ may denote various second positions at which the support  102  (e.g., the first support member  125 ) may be located by pivoting with respect to the coupler  101 . As the hinge member  123  rotates around the first rotation axis A 1 , the support  102  (e.g., the first support member  125 ) may freely pivot around the first rotation axis A 1  within an angle range of approximately 180 degrees with respect to the body  10  of the electronic device  1  or the coupler  101 . In a certain embodiment, a static friction force between the hinge member  123  and the fixing member  121  or a static friction force between the hinge member  123  (a first hinge module (e.g., the first hinge module  123   a  of  FIG.  5   )) and the fixing member  121  may maintain the support  102  in the stationary state with respect to the coupler  101 . 
     According to various embodiments, the accessory  100  may hold the body  10  inclined to a plane, with an edge of one side (e.g., a lower end of  FIG.  4   ) of the coupler  101  and the second support member  127  in contact with the plane. For example, the operation illustrated in  FIG.  7    may implement a state in which the body  10  is mounted vertically elongated with respect to the plane. The user may rotate or pivot the support  102  around the first rotation axis A 1  with respect to the coupler  101  to adjust an inclination angle of the body  10  with respect to the plane, so that the user may comfortably view the body  10  (e.g., a display). In another embodiment, when the support  102  is at a position indicated by “P 2 - 3 ”, the body  10  and/or the accessory  100  may be used as a wall mount. For example, the electronic device  1  may be used in a state in which the body  10  and/or the accessory  100  hangs on a wall of an indoor space or a hook provided inside a vehicle. In an actual use environment, for example, when used inside a moving vehicle, the body  10  and/or the accessory  100  may be stably mounted or fixed by fastening the support  102  or the coupler  101  using a plurality of hooks or holders. 
       FIG.  8    is a diagram illustrating rotation of another part of the support  102  around the second rotation axis A 2  in the accessory  100  according to various embodiments of the disclosure. 
     Referring to  FIG.  8   , the first support member  125  is shown as rotating around the second rotation axis A 2  with the support  102  (e.g., the hinge member  123  and/or the first support member  125 ) without rotating or pivoting around the first rotation axis A 1 , from the state in which the support  102  is disposed at the first position P 1 . In  FIG.  8   , ‘P 1 ’ may denote a position at which the support  102  is in contact with the coupler  101 , and ‘P 3 - n ’ may denote various second positions at which the support  102  (e.g., the second support member  125 ) may be located by pivoting with respect to the coupler  101 . As the first member  125  rotates around the second rotation axis A 2 , the support  102  (e.g., the second support member  127 ) may freely pivot around the second rotation axis A 2  within an angle range of approximately 180 degrees with respect to the body  10  of the electronic device  1  or the coupler  101 . In a certain embodiment, a static friction force between the first support member  125  and the second support member  127 , or a static friction force of the hinge member  123  (a second hinge module (e.g., the second hinge module  123   b  of  FIG.  5   ) and the first support member  125  may maintain the support  102  (e.g., the second support member  127 ) in the stationary state with respect to the coupler  101 . 
     According to various embodiments, the accessory  100  may hold the body  10  inclined to a plane, with an edge of another side of the coupler  101  (e.g., a right part of the coupler  101  adjacent to the third support member  129  at the first position P 1  of  FIG.  4   ) and the second support member  127  in contact with the plane. For example, the operation illustrated in  FIG.  8    may implement a state in which the body  10  is mounted horizontally elongated with respect to the plane. The user may rotate or pivot the support  102  around the second rotation axis A 2  with respect to the coupler  101  to adjust an inclination angle of the body  10  with respect to the plane, so that the user may comfortably view the body  10  (e.g., the display). Since this use example is similar to the embodiment of  FIG.  7   , a further detailed description will be avoided.

It will be apparent to those skilled in the art that various changes can be made in form and detail without departing from the scope of the disclosure, including the appended claims and their equivalents. For example, while ‘second position’, ‘third position’, ‘position indicated by P 2 - n ’, and ‘position indicated by P 3 - n ’ are used as positions to which a support pivots in the above-described embodiments, these expressions simply indicate exemplary angular positions to which the support is pivotable from a “first position”. According to some embodiments, these positions may be understood as “any position different from the first position”, and “any position different from the first position” may be understood as the “second position” or the “third position”.
