Patent Description:
Games or multimedia contents, which could be implemented only by PCs, are increasingly being implemented in mobile electronic devices because the processing power of the mobile electronic devices have increased. Typically, these types of content require high processing power and consume a lot of battery power. So as to smoothly drive the games or the multimedia contents on the mobile electronic devices, heat generated from internal parts (e.g., a processor) has to be dissipated.

<CIT> discusses a mobile expansion unit for use with a notebook. <CIT> discusses a cradle for use with a portable electronic appliance. <CIT> discusses a protective cover for a hand-held electronic device. <CIT> discusses a gamepad device for a mobile phone. <CIT> discusses a wireless power transmitter. <CIT> discusses a wireless charging device. <CIT> discloses another wireless charging device.

Conventionally, there may be a cooling device for a mobile electronic device which has a mounting-type structure that includes a fan that blows air toward the rear surface of the mobile electronic device. Due to the mounting-type structure, the portability of the mobile electronic device may be deteriorated, and the mobile electronic device may not be efficiently cooled by simply blowing air toward the rear surface of the mobile electronic device. Furthermore, the conventional cooling device may not stably hold the mobile electronic device. In addition, battery consumption may be increased when contents requiring high processing power are driven by using the mobile electronic device. Further, if the mobile electronic device is charged in this scenario via a wire to alleviate battery life concerns, the wire may reduce the mobility of the mobile electronic device.

The cooler for the mobile electronic device according to certain embodiments of the disclosure may optimize the fluid channel from the area of the processor, which is the primary heat-generating component of the mobile electronic device, to the fan assembly, thereby achieving high cooling efficiency. Furthermore, the cooler for the mobile electronic device may provide a mounting structure in which an external impact is not directly applied to the mobile electronic device. In addition, the cooler for the mobile electronic device may charge the mobile electronic device mounted on the cooler, by using the separate battery included in the cooler.

With regard to the description of the drawings, identical or similar reference numerals may be used to refer to identical or similar components.

It is noted that the invention as claimed is described in <FIG> and associated description. The other figures and associated description are not part of the claimed invention.

For example, the backflow prevention member <NUM> may be a ring member coupled to the fan housing <NUM> along the outer circumferential surface of the air outlet <NUM>. The backflow prevention member <NUM> may prevent air released through the air outlet <NUM> from flowing back to the space between the first cover <NUM> and the fan housing <NUM> and the space between the second cover <NUM> and the fan housing <NUM>.

In an embodiment, the battery <NUM> may be disposed between the bracket <NUM> and the second cover <NUM>. At least part of the battery <NUM> may be disposed in an area corresponding to the recess <NUM> of the housing <NUM>.

The outside air may move along the fluid channel formed from the air outlet <NUM> of the fan housing <NUM> to the first openings <NUM>.

In the illustrated embodiment, the fluid channel may be formed by the air outlet <NUM> of the fan housing <NUM>, the backflow prevention member <NUM>, the inclined surface <NUM> of the bracket <NUM>, and the inside of the first cover <NUM>.

In an embodiment, the inclined surface <NUM> of the bracket <NUM> may be formed to be inclined toward the inside of the first cover <NUM> from the second portion <NUM> of the bracket <NUM> such that the air-flow cross-sectional area of the fluid channel is decreased in the direction of air movement.

In an embodiment, the inclined surface <NUM> may be formed such that air released through the air outlet <NUM> passes through a portion the cross-sectional area of which is reduced by the inclined surface <NUM>. For example, the air flow path may be formed such that the portion adjacent to the air outlet <NUM> has a larger cross-sectional area than the portion adjacent to the first openings <NUM>. The shape of the fluid channel may enable an increase in air speed released from the air outlet <NUM> and may therefore have an advantage in dissipating heat generated from the electronic device <NUM>. For example, the air speed released from the fan assembly <NUM> may increase with a decrease in the air-flow cross-sectional area. This means that part of the internal energy of air is converted to kinetic energy. The temperature of air may be decreased during the passage of air through the fluid channel. Furthermore, air with increasing speed may be advantageous for convection heat transfer in the recess <NUM>.

In an embodiment, the primary source of heat, such as the processor <NUM> of the electronic device <NUM>, may be disposed in a position corresponding to the recess <NUM>.

In some embodiments, the cooler <NUM> may be configured in a closed state in which the guide plate <NUM> is located in the first housing 110a and the second housing 110b and an open state in which at least part of the guide plate <NUM> is located between the first housing 110a and the second housing 110b.

Referring to <FIG>, the distance between the first fixing portion <NUM> and the second fixing portion <NUM> of the cooler <NUM> may be increased as the second housing 110b slides by a predetermined distance from the first housing 110a. The electronic device <NUM> may be mounted on the cooler <NUM> such that the connector <NUM> is coupled with the connector <NUM> formed on the first fixing portion <NUM> and at least part of the rear surface <NUM> of the electronic device <NUM> is seated on the first seating area <NUM> of the first housing 110a and the second seating area <NUM> of the second housing 110b.

After the electronic device <NUM> is seated on the cooler <NUM>, the distance between the first fixing portion <NUM> and the second fixing portion <NUM> may be decreased as the second housing 110b slides toward the first housing 110a. At this time, the pair of edges of the electronic device <NUM> facing each other may be disposed on the first fixing portion <NUM> and the second fixing portion <NUM>, and thus the electronic device <NUM> may be mounted on the cooler <NUM>.

In an embodiment, the cooler <NUM> may provide an open state in which the rear surface <NUM> of the electronic device <NUM> is able to be seated on the seating areas <NUM> and a closed state in which the seated electronic device <NUM> is fixed. In an embodiment, the cooler <NUM> may be configured in an open state in which a mounting space larger than the electronic device <NUM> is formed and a closed state in which a mounting space corresponding to the electronic device <NUM> is formed.

<FIG> are views illustrating a sliding structure and a sliding motion of the cooler for the mobile electronic device according to an embodiment.

In an embodiment, the cooler <NUM> may include the first housing 110a, the second housing 110b slidably coupled to the first housing 110a, and the sliding structure <NUM> by which the first housing 110a and the second housing 110b are slidably coupled together.

Referring to <FIG>, in the closed state, the first housing 110a and the second housing 110b may be brought into contact with each other. Referring to <FIG>, in the open state, the first housing 110a and the second housing 110b may be spaced apart from each other.

In the illustrated embodiment, the sliding structure <NUM> may include the guide plate <NUM> that extends toward the second housing 110b from the interior of the first housing 110a and that is at least partially located in the second housing 110b, a guide rail <NUM> formed in the guide plate <NUM>, and a guide protrusion <NUM> formed on the second housing 110b and at least partially inserted into the guide rail <NUM>.

In the illustrated embodiment, the guide plate <NUM> may extend from the interior of the first housing 110a in a sliding direction. In the closed state, the guide plate <NUM> may be located in the second housing 110b, and in the open state, at least part of the guide plate <NUM> may be located between the first housing 110a and the second housing 110b.

In the illustrated embodiment, the guide rails <NUM> may be formed in the guide plate <NUM> and may extend in the sliding direction. One or more guide rails <NUM> may be formed in the guide plate <NUM>. The extension length of the guide rails <NUM> may correspond to the distance by which the first housing 110a and the second housing 110b can be maximally spaced apart from each other when the cooler <NUM> moves from the closed state to the open state.

In an embodiment, each of the guide rails <NUM> may include a first end portion closer to the first housing 110a and a second end portion closer to the second housing 110b. In the closed state, the guide protrusion <NUM> may be located in the first end portion of the guide rail <NUM>. In the open state, the guide protrusion <NUM> may be located in the second end portion of the guide rail <NUM>.

In an embodiment, the guide rails <NUM> may be formed on one surface of the guide plate <NUM>. The one surface may be a surface that faces a direction perpendicular to the sliding direction. For example, referring to <FIG>, the guide rails <NUM> may be formed on the surface of the guide plate <NUM> that faces the first surface <NUM> of the housing <NUM>. However, the guide rails <NUM> are not necessarily formed on the surface of the guide plate <NUM> that faces the first surface <NUM> or the second surface <NUM> of the housing <NUM>. In another example, the guide rails <NUM> may be formed on one surface of the guide plate <NUM> that is opposite the third surface <NUM> of the housing <NUM> that faces a direction perpendicular to the sliding direction.

In an embodiment, the sliding structure <NUM> may include a positioning protrusion <NUM> formed on one surface of the guide plate <NUM> and positioning recesses that are formed on a facing surface <NUM> facing the one surface of the guide plate <NUM> and in which the positioning protrusion <NUM> is located. The one surface on which the positioning protrusion <NUM> is formed may be a surface that faces a direction perpendicular to the sliding direction. For example, referring to <FIG>, the positioning protrusion <NUM> may protrude from the one surface of the guide plate <NUM> to face the direction perpendicular to the sliding direction. However, the positioning protrusion <NUM> is not necessarily formed on the surface of the guide plate <NUM> that is opposite the third surface <NUM> of the housing <NUM>. In another example, the positioning protrusion <NUM> may be formed on one surface of the guide plate <NUM> that faces the first surface <NUM> or the second surface <NUM> of the housing <NUM>.

In an embodiment, a first positioning recess <NUM> may be formed in a position corresponding to the second end portion of the guide rail <NUM>. A second positioning recess <NUM> may be formed in a position corresponding to the first end portion of the guide rail <NUM>.

In an embodiment, the positioning protrusion <NUM> and the positioning recesses <NUM> and <NUM> may be formed to maintain the closed state or the open state of the cooler <NUM>.

For example, when the cooler <NUM> is in the closed state, the positioning protrusion <NUM> may be inserted into the first positioning recess <NUM>, and the positions of the first housing 110a and the second housing 110b may be fixed. Alternatively, when the cooler <NUM> is in the open state, the positioning protrusion <NUM> may be inserted into the second positioning recess <NUM>, and the positions of the first housing 110a and the second housing 110b may be fixed.

In an embodiment, the guide plate <NUM> may include an elastic portion <NUM> on which the positioning protrusion <NUM> is formed. The elastic portion <NUM> may be formed to provide elastic force in the direction in which the positioning protrusion <NUM> protrudes. For example, referring to <FIG>, the elastic portion <NUM> may extend from the rest of the guide plate <NUM> in a direction perpendicular to the sliding direction. An opening <NUM> may be formed between the elastic portion <NUM> and the guide plate <NUM>.

In an embodiment, the elastic portion <NUM> may be bent toward the opening <NUM> when the positioning protrusion <NUM> formed on the guide plate <NUM> is located between the first positioning recess <NUM> and the second positioning recess <NUM> (e.g., in an intermediate state between the closed state and the open state). The bent elastic portion <NUM> may be straightened to provide the elastic force when the positioning protrusion <NUM> is located in the first positioning recess <NUM> or the second positioning recess <NUM>.

In an embodiment, the sliding structure <NUM> may include a first magnet <NUM> formed on the guide plate <NUM> and a second magnet <NUM> formed in the second housing 110b. The first magnet <NUM> and the second magnet <NUM> may attract each other while facing each other. For example, when the cooler <NUM> is in the intermediate state between the closed state and the open state, the first magnet <NUM> and the second magnet <NUM> may slide the guide plate <NUM> in the direction of the arrow illustrated in <FIG>, such that the cooler <NUM> is switched to the closed state. In other words, when the positioning protrusion <NUM> is located between the first positioning recess <NUM> and the second positioning recess <NUM>, the first magnet <NUM> and the second magnet <NUM> may move the guide plate <NUM> in the direction of the arrow illustrated in <FIG>, such that the positioning protrusion <NUM> is inserted into the first positioning recess <NUM>.

In an embodiment, the sliding structure <NUM> may include an elastic member that is coupled, at one side thereof, to the second housing 110b and is coupled, at an opposite side thereof, to the guide plate <NUM>. The elastic member may include a spring. For example, when the cooler <NUM> is in the open state, the spring may be extended and may provide elastic force in the direction in which the first housing 110a and the second housing 110b move toward each other, and when the cooler <NUM> is in the closed state, the spring may be substantially in equilibrium.

Accordingly, the cooler <NUM> may maintain the closed state and prevent an unintended open state when the user does not intend to open the cooler <NUM>, thereby preventing separation of the electronic device <NUM> mounted on the cooler <NUM>.

In <FIG>, it is shown that the guide plate <NUM> is included in the first housing 110a, and the guide protrusion <NUM>, the positioning recesses <NUM> and <NUM>, and the magnets <NUM> and <NUM> are included in the second housing 110b.

Referring to <FIG>, the pad member <NUM> and the seating member <NUM> may be separate components disposed on the first surface <NUM> of the housing <NUM>. Without being necessarily limited thereto, however, the seating member <NUM> may be integrally formed with the first surface <NUM> of the housing <NUM>.

In the illustrated embodiment, the pad area <NUM> and a seating area <NUM> surrounding the pad area <NUM> may be formed on the second portion 310b of the housing <NUM>. The pad area <NUM> may be concavely formed in the direction from the first surface <NUM> of the housing <NUM> to the second surface <NUM> thereof. The seating area <NUM> may include a peripheral portion of the pad area <NUM>. An electronic device (e.g., the electronic device <NUM> of <FIG>) may be disposed on the seating area <NUM>.

In an embodiment, the electronic device that is seated on the seating area <NUM> may be a portable communication device (e.g., a smartphone), a portable multimedia device, a portable medical device, a camera, a wearable electronic device (e.g., a smart watch or a smart band), or a home appliance. The electronic device according to the embodiment of the disclosure is not limited to the aforementioned devices.

The second openings <NUM> may be formed through the third surface <NUM> of the housing <NUM> to be in fluidic communication with the interior space of the housing <NUM>.

<FIG> is an exploded perspective view of the accessory according to an embodiment.

Referring to <FIG>, the accessory <NUM> according to an embodiment may include a first cover <NUM>, a second cover <NUM>, a fan assembly <NUM>, a duct member <NUM>, first wireless charging circuitry <NUM>, the pad member <NUM>, a printed circuit board <NUM>, and second wireless charging circuitry <NUM>.

In the illustrated embodiment, the first cover <NUM> may be coupled with the second cover <NUM> to form the housing <NUM> illustrated in <FIG>. The first cover <NUM> may substantially form the first surface <NUM> of the housing <NUM> and a portion of the third surface <NUM> of the housing <NUM>. The opening <NUM> may be formed in the first cover <NUM>. The pad member <NUM> and the first wireless charging circuitry <NUM> may be disposed in the opening <NUM>. The first cover <NUM> may include a first area (e.g., corresponding to the first portion 310a of the housing <NUM> of <FIG>) in which the first wireless charging circuitry <NUM> and the fan assembly <NUM> are disposed and a second area (e.g., corresponding to the second portion 310b of the housing <NUM> of <FIG>) in which the second wireless charging circuitry <NUM> is disposed. The first cover <NUM> may be coupled with the second cover <NUM> to form a space in which the fan assembly <NUM>, the duct member <NUM>, the second wireless charging circuitry <NUM>, and the printed circuit board <NUM> are disposed.

In the illustrated embodiment, the printed circuit board <NUM> may be formed on the inside of the first cover <NUM> so as to be adjacent to the first wireless charging circuitry <NUM> and the second wireless charging circuitry <NUM>.

In the illustrated embodiment, the second cover <NUM> may substantially form the second surface <NUM> of the housing <NUM> and the remaining portion of the third surface <NUM> of the housing <NUM>. The second cover <NUM> may include the first intake area <NUM> including the plurality of first openings <NUM> formed through the second surface <NUM> of the housing <NUM> and the second intake areas <NUM>, each of which includes the plurality of second openings <NUM> formed through the third surface <NUM> of the housing <NUM>.

In the illustrated embodiment, the fan assembly <NUM> may be disposed under the opening <NUM> formed in the first cover <NUM>. The fan assembly <NUM> may be in fluidic communication with the first cover <NUM> through the duct member <NUM>. The fan assembly <NUM> may include a fan bracket <NUM>, a rotary shaft <NUM> disposed on the fan bracket <NUM>, and a plurality of rotary blades <NUM> extending from the rotary shaft <NUM> in the radial direction. The rotary shaft <NUM> may extend in the same direction R as the direction that the fan bracket <NUM> faces. The fan bracket <NUM> may be connected with the duct member <NUM>. Accordingly, the duct member <NUM> may connect the fan bracket <NUM> and the inside of the first cover <NUM> to form an enclosed space. The fan bracket <NUM> and the duct member <NUM> may prevent air flowing from the fan assembly <NUM> from being released to other interior spaces in the first cover <NUM> and the second cover <NUM>. In some embodiments, the housing <NUM> may have a recess structure, the duct member <NUM> may form the inner wall of the recess structure, and the fan bracket <NUM> may form the bottom of the recess structure.

In the illustrated embodiment, the second cover <NUM> may include support members <NUM> coupled to the lower surface thereof. The support members <NUM> may space the second cover <NUM> apart from the ground by a predetermined gap to allow air to smoothly flow into the first intake area <NUM> formed on the second cover <NUM>.

<FIG> is a view illustrating an air flow path in the accessory according to an embodiment.

Referring to <FIG>, outside air may be introduced into the housing <NUM> through the second intake areas <NUM> and the first intake area <NUM> that are formed on the second cover <NUM>. Air introduced through the second intake areas <NUM> may be moved toward the first portion 310a of the housing <NUM> by operation of the fan assembly <NUM>.

Referring to <FIG>, an enclosed space <NUM> connected to the opening <NUM> may be formed in the housing <NUM>. The enclosed space <NUM> may be formed by the fan bracket <NUM>, the duct member <NUM>, and the inside of the first cover <NUM> that are connected together. For example, the fan assembly <NUM> may be disposed in the housing <NUM> such that the fan bracket <NUM> forms the bottom of the enclosed space <NUM> and the rotary shaft <NUM> is formed in the direction toward the bottom of the enclosed space <NUM>. The duct member <NUM> formed to surround the plurality of rotary blades <NUM> may be disposed on the fan bracket <NUM>. The duct member <NUM> may be coupled, at one side thereof, with the inside of the first cover <NUM> and may be coupled, at an opposite side thereof, with the fan bracket <NUM>.

In the illustrated embodiment, the first wireless charging circuitry <NUM> may be disposed in the enclosed space <NUM>. The first wireless charging circuitry <NUM> may be disposed on a support plate <NUM> connected to the inner circumferential surface of the opening <NUM> of the first cover <NUM>. The first wireless charging circuitry <NUM> may be disposed to be spaced apart from the fan assembly <NUM> by a predetermined gap.

In the illustrated embodiment, the duct member <NUM> may have a conical shape that increases in diameter toward the first surface <NUM> of the housing <NUM>. The pad member <NUM> may be formed to be larger than the duct member <NUM>. The fan bracket <NUM> of the fan assembly <NUM> may be formed to be smaller than the pad member <NUM>. Accordingly, when the first surface <NUM> of the housing <NUM> is viewed from above, the pad member <NUM> may prevent the fan bracket <NUM> and the inner wall of the duct member <NUM> from being exposed to the outside. In the case where the fan bracket <NUM> and the duct member <NUM> are visually exposed through the first surface <NUM> of the housing <NUM>, the visual appearance of the accessory may be deteriorated. Alternatively, in the case where air released from the fan assembly <NUM> is directly discharged to the user through the opening <NUM> of the housing <NUM> (e.g., direct wind), the user may feel an inconvenience. Accordingly, as illustrated in the drawing, the pad member <NUM> may be formed to be larger than the fan assembly <NUM>, the first wireless charging circuitry <NUM>, and the duct member <NUM> to allow air released from the fan assembly <NUM> to be discharged out of the housing <NUM> through between the pad member <NUM> and the inner circumferential surface of the opening <NUM> while flowing along the lower surface of the first wireless charging circuitry <NUM>. That is, by forming the air flow path in the form of a curve, air may not be directly discharged to the user (e.g., indirect wind) even in the case where no electronic device is mounted on the pad member <NUM>.

In an embodiment, air for cooling the second wireless charging circuitry <NUM> and the printed circuit board <NUM> may be introduced through the second intake area <NUM> adjacent to the second portion 310b.

In an embodiment, outside air introduced through the first intake area <NUM> and the second intake area <NUM> that is adjacent to the first portion 310a may flow toward the lower surface of the first wireless charging circuitry <NUM> by the fan assembly <NUM>.

In the illustrated embodiment, the flow path of air in the housing <NUM> may be broadly classified into two flow paths. The first flow path A may be a path along which air is introduced into the first portion 310a of the housing <NUM> and is discharged via the first wireless charging circuitry <NUM> and the pad member <NUM>. The second flow path B may be a path along which air is introduced into the second portion 310b of the housing <NUM> and is moved toward the first portion 310a. Part of air flowing along the second flow path B may be used to cool the printed circuit board <NUM> and the second wireless charging circuitry <NUM>.

In the illustrated embodiment, air introduced through the first intake area <NUM> and the second intake area <NUM> may be introduced, along the first flow path A, between the rotary blades <NUM> through an opening formed in the fan bracket <NUM> of the fan assembly <NUM>. The air may be drawn into the opening <NUM> through the enclosed space <NUM> defined by the duct member <NUM> by the rotary blades <NUM>. At this time, the pad member <NUM> and the peripheral area of the opening <NUM> may be spaced apart from each other by a predetermined gap <NUM>. The air may be discharged toward the electronic device mounted on the seating member <NUM>, which is disposed on top of the opening <NUM>, through the gap <NUM>. Accordingly, the electronic device may be cooled.

In an embodiment, the seating member <NUM> may be formed on the peripheral area of the opening <NUM>, and the pad member <NUM> spaced apart from the peripheral area of the opening <NUM> by the predetermined gap <NUM> may be disposed in the opening <NUM>. For example, the pad member <NUM> may be formed to be smaller than the opening <NUM>. Air in the housing <NUM> may be discharged to the surface of the housing <NUM> through the gap <NUM>. At this time, the pad member <NUM> may have a predetermined height difference from the seating member <NUM>. The height difference may define a space to which air released from the interior of the housing <NUM> is finally discharged.

The accessory <NUM> according to an embodiment may simultaneously provide a wireless charging function and a cooling function. So as to dissipate heat generated from the first wireless charging circuitry <NUM> as well as simply cooling the electronic device, the accessory <NUM> may include the first wireless charging circuitry <NUM> stacked in the discharge direction of the fan assembly <NUM>. Furthermore, at least part of an air flow path (e.g., the flow path B) that is formed in the housing <NUM> of the accessory <NUM> may pass through the second wireless charging circuitry <NUM> and the printed circuit board <NUM> to dissipate heat generated from the second wireless charging circuitry <NUM> and the printed circuit board <NUM>.

In some embodiments, an electronic device may include a function of preventing overheating by lowering a wireless charging rate when the temperature of the electronic device is higher than or equal to a specific temperature. In this case, the accessory <NUM> disclosed herein may simultaneously provide wireless charging and cooling to the electronic device, thereby preventing overheating of the electronic device and preventing the reduction in the charging rate. In an embodiment, the first wireless charging circuitry <NUM> may have a relatively high output (e.g., fast charging), compared with the second wireless charging circuitry <NUM>.

In an embodiment, the first wireless charging circuitry <NUM> may be formed to be thinner than the second wireless charging circuitry <NUM>. For example, the first wireless charging circuitry <NUM> may include a single coil, and the second wireless charging circuitry <NUM> may include a double coil having single coils stacked on each other. The first wireless charging circuitry <NUM> and the electronic device may be spaced apart from each other by a predetermined gap to form an air flow path therebetween. The first wireless charging circuitry <NUM> may include a relatively thin coil such that the gap does not affect the charging function of the first wireless charging circuitry <NUM>.

In an embodiment, the second wireless charging circuitry <NUM> may include a Tx coil having a relatively small outer diameter. The aim may be to stably provide wireless charging to an electronic device, such as a wearable electronic device (e.g., a smart watch or a smart band), which includes an Rx coil having a relatively small outer diameter. For example, in the case where the second wireless charging circuitry <NUM> includes a Tx coil having a relatively large outer diameter, the Tx coil having the relatively large outer diameter may affect another metal portion (e.g., a display or a housing) of the wearable electronic device.

In an embodiment, the second wireless charging circuitry <NUM> may include a Tx coil stacked in the form of a double coil. The aim may be to efficiently provide wireless charging to a wearable electronic device (e.g., a smart watch or a smart band). Wireless charging efficiency may be improved with an increase in the area where a coil is formed and the number of times that the coil is wound. Accordingly, the second wireless charging circuitry <NUM> may include a Tx coil that has a relatively small outer diameter and that is formed by stacking, thereby efficiently providing wireless charging to a wearable electronic device having a small Rx coil.

In an embodiment, the seating member <NUM> may include a ring member having a substantially ring shape. At least part of the seating member <NUM> may further protrude beyond the first surface <NUM> of the housing <NUM>. The aim may be to form an air flow path between the rest of the seating member <NUM> and an electronic device when the electronic device is seated on the protrusion of the seating member <NUM>.

<FIG> is a view illustrating the coupling of the first wireless charging circuitry, the duct member, and the fan assembly of the accessory according to an embodiment.

Referring to <FIG>, the first wireless charging circuitry <NUM> may be disposed on a plate structure <NUM> in the opening <NUM> formed in the first cover <NUM>. The plate structure <NUM> may be connected with the inner circumferential surface of the opening <NUM> of the first cover <NUM>. The plate structure <NUM> may have a through-hole <NUM> formed therein, through which a connecting member <NUM> extending from the first wireless charging circuitry <NUM> can pass to connect to a printed circuit board (e.g., the printed circuit board <NUM> of <FIG>). The connecting member <NUM> may extend into the first cover <NUM> through the through-hole <NUM>.

In the illustrated embodiment, the pad member <NUM> may be disposed over the plate structure <NUM>. The first wireless charging circuitry <NUM> may be disposed between the plate structure <NUM> and the pad member <NUM>. The first wireless charging circuitry <NUM> may be coupled to the first cover <NUM> by coupling the support plate <NUM> to the plate structure <NUM>. The opening <NUM> may be formed to be larger than the pad member <NUM>, and therefore the periphery of the pad member <NUM> and the inner circumferential surface of the opening <NUM> may be spaced apart from each other by at least a predetermined gap.

In the illustrated embodiment, at least part of the seating member <NUM> may further protrude beyond the pad member <NUM> in the direction toward the first surface <NUM> of the housing <NUM>. Accordingly, a surface (e.g., the rear surface) of an electronic device (e.g., the electronic device <NUM> of <FIG>) may be spaced apart from the pad member <NUM> by a predetermined gap. Furthermore, the electronic device may be spaced apart from the first wireless charging circuitry <NUM> by a predetermined gap, and the predetermined gap may be an appropriate distance at which the first wireless charging circuitry <NUM> is capable of providing a wireless charging function to the electronic device.

<FIG> is a view illustrating the coupling of the fan assembly, the duct member, and the first cover of the accessory according to an embodiment.

Referring to <FIG>, the fan bracket <NUM> may be connected with the duct member <NUM>, and the duct member <NUM> may be connected with an inner surface <NUM> of the first cover <NUM>. The duct member <NUM> may be formed between the fan bracket <NUM> and the inner surface <NUM> of the first cover <NUM>. Accordingly, the duct member <NUM> may form a fluid channel (e.g., the enclosed space <NUM> of <FIG>) that is enclosed such that air released from the fan assembly <NUM> is discharged toward the opening <NUM>.

In the illustrated embodiment, the duct member <NUM> may include a fastening part <NUM> coupled to the inner surface <NUM> of the first cover <NUM> with a screw and a sidewall part <NUM> substantially corresponding to the peripheral area of the opening <NUM>. One side of the sidewall part <NUM> may be coupled with the fan bracket <NUM>, and an opposite side of the sidewall part <NUM> may be located on the peripheral area of the opening <NUM> that is located on the inner surface <NUM> of the first cover <NUM>.

In the illustrated embodiment, the fan bracket <NUM> may have one or more air inlets <NUM> formed therein. The air inlets <NUM> may be formed to have a size substantially corresponding to the radius of rotation of the plurality of rotary blades <NUM> of the fan assembly <NUM>. Accordingly, air in the housing <NUM> is able to move only in the direction toward the pad member <NUM> through the fan bracket <NUM> and is unable to move in the reverse direction. That is, the structure may prevent backflow of air introduced into the interior space of the duct member <NUM> by the fan assembly <NUM>.
