HOUSING HAVING VENTILATION MEMBER ARRANGED THEREIN, AND ELECTRONIC DEVICE COMPRISING SAME

BACKGROUND
1. Field

The disclosure described relates to a housing having a ventilation member disposed therein and an electronic device including the same.

2. Description of Related Art

An electronic device may include a housing that forms an exterior. Various parts of the electronic device may be disposed in the housing. The inside of the housing may have an environment different from an external environment. For example, when the electronic device is exposed to a temperature change or an altitude change, the pressure in the housing and the pressure in the external environment may differ from each other. Due to the difference between the environments, the humidity in the housing may increase so that the housing may be covered with dew, or a sealing member, such as a gasket may be weakened so that foreign matter, such as dust or moisture may infiltrate into the housing. Therefore, the performance of the electronic device may be deteriorated.

To reduce the difference between the environment in the housing and the external environment, a method of maintaining an equilibrium state by forming a ventilation hole fluidically connected with the external environment in the housing has been used.

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.

SUMMARY

For example, the ventilation hole fluidically connecting the inside and the outside of the electronic device may be formed in a housing of a camera module exposed outside the electronic device. However, since lenses, a flash, and microphone holes are densely arranged in the camera module, there may be a limitation in the design of the ventilation hole (e.g., a limitation in the area and the shape of the ventilation hole), and it may be difficult to secure ventilation performance required for the electronic device. In addition, the ventilation hole exposed to the outside may spoil the aesthetics of the electronic device.

Aspects 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, an aspect of the disclosure is to provide a housing having a ventilation member disposed therein and an electronic device including the same for securing required ventilation performance without spoiling the aesthetics of the electronic device.

Additional aspects will be set forth in part in the description which follows and, in part, will be apparent from the description, or may be learned by practice of the presented embodiments.

In accordance with an aspect of the disclosure, an electronic device is provided. The electronic device includes a housing that forms a side surface and an inner space of the electronic device and a ventilation member. The housing includes an opening located in the side surface, a receiving hole that extends from the opening such that an external device is accommodated in the receiving hole, and a through-hole that fluidically connects the receiving hole and the inner space. The ventilation member is disposed in the housing to cover the through-hole.

In accordance with an aspect of the disclosure, a housing of an electronic device is provided. The housing includes a support member, a cover disposed on the support member, and a ventilation member. The support member and the cover form an inner space of the housing together. The support member includes a receiving hole in which an electronic pen is accommodated and a through-hole that fluidically connects the receiving hole and the inner space. The ventilation member is disposed on the support member to cover the through-hole.

According to an embodiment of the disclosure, the degree of freedom in the design of the through-hole may be secured depending on required ventilation performance.

According to an embodiment of the disclosure, the ventilation hole may be formed in the receiving hole in which the external device (e.g., the electronic pen) is accommodated. Accordingly, ventilation performance may be secured without spoiling the design aesthetics of the electronic device.

According to an embodiment of the disclosure, since the ventilation hole is formed in the receiving hole in which the external device is accommodated, optimized design may be produced depending on required ventilation performance, and a reduction in manufacturing costs and an improvement in productivity may be achieved through simplification of a manufacturing process.

Other aspects, advantages, and salient features of the disclosure will become apparent to those skilled in the art from the following detailed description, which, taken in conjunction with the annexed drawings, discloses various embodiments of the disclosure.

In another embodiment of the disclosure, the front plate 102 (or, the back plate 111) may include only one of the first regions 110D (or, the second regions 110E). Furthermore, in another embodiment of the disclosure, the front plate 102 (or, the back plate 111) may not include a part of the first regions 110D (or, the second regions 110E).

In an embodiment of the disclosure, when viewed from a side of the electronic device 101, the side bezel structure 118 may have a first thickness (or, width) at sides (e.g., short sides) not including the first regions 110D or the second regions 110E and may have a second thickness at sides (e.g., long sides) including the first regions 110D or the second regions 110E, the second thickness being smaller than the first thickness.

In an embodiment of the disclosure, the electronic device 101 may include at least one of a display 106, audio modules 103, 104 and 107 (e.g., an audio module 470 of FIG. 4), a sensor module (not illustrated) (e.g., a sensor module 476 of FIG. 4), camera modules 105, 112, and 113 (e.g., a camera module 480 of FIG. 4), key input devices 117 (e.g., an input module 450 of FIG. 4), a light emitting element (not illustrated), or a connector hole 108 (e.g., a connecting terminal 478 of FIG. 4).

In an embodiment of the disclosure, the periphery of the display 106 may be formed to be substantially the same as the shape of the adjacent outside edge of the front plate 102. In another embodiment (not illustrated) of the disclosure, to expand the area by which the display 106 is exposed, the gap between the periphery of the display 106 and the periphery of the front plate 102 may be formed to be substantially constant.

In an embodiment of the disclosure, a surface of the housing 110 (or, the front plate 102) may include a screen display region that is formed as the display 106 is visually exposed. For example, the screen display region may include the first surface 110A and the first regions 110D of the side surface.

In another embodiment (not illustrated) of the disclosure, the screen display region 110A and 110D may include a sensing region (not illustrated) that is configured to obtain biometric information of a user. When the screen display region 110A and 110D includes the sensing region, this may mean that at least a portion of the sensing region overlaps the screen display region 110A and 110D. For example, the sensing region (not illustrated) may refer to a region capable of displaying visual information by the display 106 like other areas of the screen display region 110A and 110D and additionally obtaining biometric information (e.g., a fingerprint) of the user.

In an embodiment of the disclosure, the first camera module 105 may be exposed through a portion of the screen display region 110A and 110D of the display 106. For example, the first camera module 105 may be exposed on a partial area of the screen display region 110A and 110D through an opening (not illustrated) that is formed in a portion of the display 106.

In an embodiment of the disclosure, the second camera module 112 may include a plurality of camera modules (e.g., a dual camera, a triple camera, or a quad camera). However, the second camera module 112 is not necessarily limited to including the plurality of camera modules and may include one camera module.

The first camera module 105 and the second camera module 112 may include one or more lenses, an image sensor, and/or an image signal processor. The flash 113 may include, for example, a light emitting diode or a xenon lamp. In another embodiment of the disclosure, two or more lenses (an IR camera lens, a wide angle lens, and a telephoto lens) and image sensors may be disposed on one surface of the electronic device 101.

In an embodiment of the disclosure, the key input devices 117 may be disposed on the side surface 110C (e.g., the first regions 110D and/or the second regions 110E) of the housing 110. In another embodiment of the disclosure, the electronic device 101 may not include all or some of the key input devices 117, and the key input devices 117 not included may be implemented in a different form, such as a soft key, on the display 106. In another embodiment of the disclosure, the key input devices may include a sensor module (not illustrated) that forms the sensing region (not illustrated) that is included in the screen display region 110A and 110D.

In an embodiment of the disclosure, the connector hole 108 may accommodate a connector. The connector hole 108 may be disposed in the side surface 110C of the housing 110. For example, the connector hole 108 may be disposed in the side surface 110C so as to be adjacent to at least a part of the audio modules (e.g., the microphone hole 103 and the speaker hole 107). In another embodiment of the disclosure, the electronic device 101 may include the first connector hole 108 capable of accommodating a connector (e.g., a USB connector) for transmitting/receiving power and/or data with an external device, and/or a second connector hole (not illustrated) capable of accommodating a connector (e.g., an earphone jack) for transmitting/receiving an audio signal with an external device.

In an embodiment of the disclosure, the electronic device 101 may include the light emitting element (not illustrated). For example, the light emitting element (not illustrated) may be disposed on the first surface 110A of the housing 110. The light emitting element (not illustrated) may provide state information of the electronic device 101 in the form of light. In another embodiment of the disclosure, the light emitting element (not illustrated) may provide a light source that operates in conjunction with operation of the first camera module 105. For example, the light emitting element (not illustrated) may include an LED, an IR LED, and/or a xenon lamp.

A pen input device 185 (e.g., a stylus pen) may be inserted into, or detached from, the housing 110 through a hole 121 formed in the side surface of the housing 110 and may include a button for facilitating the detachment. The pen input device 185 may have a separate resonance circuit embedded therein and may operate in conjunction with an electromagnetic induction panel (e.g., an electromagnetic induction panel 190 of FIG. 1C) included in the electronic device 101. The pen input device 185 may include an electro-magnetic resonance (EMR) type, an active electrical stylus (AES) type, and an electric coupled resonance (ECR) type.

FIG. 1C is an exploded perspective view of an electronic device according to an embodiment of the disclosure.

Referring to FIG. 1C, the electronic device 101 may include a front plate 120 (e.g., the front plate 102 of FIG. 1A), a display 130 (e.g., the display 106 of FIG. 1A), the electromagnetic induction panel 190, a first support member 140 (e.g., a bracket), a battery 149, a printed circuit board 150, a second support member 160 (e.g., a rear case), and a back plate 180 (e.g., the back plate 111 of FIG. 1B).

The electromagnetic induction panel 190 (e.g., a digitizer) may be a panel for sensing an input of the pen input device 185. For example, the electromagnetic induction panel 190 may include a printed circuit board (PCB) (e.g., a flexible printed circuit board (FPCB)) and a shield sheet. The shield sheet may prevent interference between the components by electromagnetic fields generated from the components (e.g., the display module, the printed circuit board, and the electromagnetic induction panel) that are included in the electronic device 101. The shield sheet may block the electromagnetic fields generated from the components, thereby enabling an input from the pen input device 185 to be accurately transferred to a coil included in the electromagnetic induction panel 190. The electromagnetic induction panel 190 according to various embodiments may include an opening formed in at least a partial region corresponding to a biosensor mounted in the electronic device 101.

In an embodiment of the disclosure, the first support member 140 may include the frame structure 141 that forms a surface of the electronic device 101 (e.g., a portion of the side surface 110C of FIG. 1A) and a plate structure 142 that extends from the frame structure 141 toward the inside of the electronic device 101.

The plate structure 142 may be located inside the electronic device 101 and may be connected with the frame structure 141, or may be integrally formed with the frame structure 141. The plate structure 142 may be formed of, for example, a metallic material and/or a non-metallic (e.g., polymer) material. The display 130 may be coupled to one surface of the plate structure 142, and the printed circuit board 150 may be coupled to an opposite surface of the plate structure 142. In an embodiment of the disclosure, a processor, a memory, and/or an interface may be mounted on the printed circuit board 150 and may be electrically connected with a circuit pattern of the printed circuit board 150. The processor may include, for example, one or more of a central processing unit, an application processor, a graphic processing unit, an image signal processor, a sensor hub processor, or a communication processor.

The memory may include, for example, a volatile memory or a non-volatile memory.

For example, the battery 149 may include a primary cell that is not rechargeable, a secondary cell that is rechargeable, or a fuel cell. In an embodiment of the disclosure, at least a portion of the battery 149 may be disposed on substantially the same plane as the printed circuit board 150. In an embodiment of the disclosure, the battery 149 may be integrally disposed inside the electronic device 101, or may be disposed so as to be detachable from the electronic device 101.

FIG. 2A is a sectional view of an electronic device according to an embodiment of the disclosure. FIG. 2A may be a sectional view taken along line A-A′ of FIG. 1A.

FIG. 2B is a sectional view of an electronic device according to an embodiment of the disclosure. FIG. 2B may be a sectional view taken along line B-B′ of FIG. 1A.

FIG. 3 illustrates a support member having a ventilation member disposed thereon according to an embodiment of the disclosure.

Referring to FIGS. 2A and 2B, an electronic device 201 according to an embodiment of the disclosure (e.g., the electronic device 101 of FIG. 1A) may include a housing 210, a ventilation member 250, and an adhesive member 260.

In an embodiment of the disclosure, the housing 210 (e.g., the housing 110 of FIG. 1A) may include a cover 220 and a support member 240.

In an embodiment of the disclosure, the cover 220 (e.g., the front plate 120 or the back plate 180 of FIG. 1C) may be disposed on the support member 240. In an embodiment of the disclosure, a recess formed on the support member 240 may be at least partially closed by the cover 220, and an inner space 10 may be formed accordingly. In an embodiment of the disclosure, various components of the electronic device 201 (e.g., the printed circuit board 150 of FIG. 1C) may be disposed in the inner space 10 of the housing 210.

In an embodiment of the disclosure, the support member 240 (e.g., the first support member 140 and/or the second support member 160 of FIG. 1C) may form at least a portion of a side surface 210C of the electronic device 201 (e.g., the side surface 110C of FIG. 1A). In an embodiment of the disclosure, the support member 240 may have an opening 22 formed therein. For example, the opening 22 may be formed in the side surface 210C. In an embodiment of the disclosure, a receiving hole 20 extending from the opening 22 toward the inside of the electronic device 201 may be formed in the support member 240. For example, the receiving hole 20 may extend from the opening 22 in a first direction 1 (e.g., the +Y direction of FIG. 1A). In an embodiment of the disclosure, a pen input device of the electronic device 201 (e.g., the pen input device 185 of FIG. 1C) may be accommodated in the receiving hole 20.

In an embodiment of the disclosure, the support member 240 may include a first surface 240A adjacent to the inner space 10 and a second surface 240B adjacent to the receiving hole 20. At least a portion of the inner space 10 may be formed by the first surface 240A of the support member 240, and at least a portion of the receiving hole 20 may be formed by the second surface 240B of the support member 240.

In an embodiment of the disclosure, a through-hole 30 extending from the first surface 240A to the second surface 240B may be formed in the support member 240. In an embodiment of the disclosure, the through-hole 30 may fluidically connect the receiving hole 20 and the inner space 10.

In an embodiment of the disclosure, the ventilation member 250 may be disposed on the support member 240 to cover an open side of the through-hole 30 formed in the support member 240. In an embodiment of the disclosure, the ventilation member 250 may be attached to the support member 240 through the adhesive member 260. In an embodiment of the disclosure, the adhesive member 260 may include an adhesive liquid or an adhesive tape that contains a silicone-based resin and/or an acrylic-based resin, but is not limited thereto.

In an embodiment of the disclosure, the through-hole 30 formed in the support member 240 may include a first opening 32 and a second opening 34 that have different areas. The first opening 32 may be located between the inner space 10 and the second opening 34, and the second opening 34 may be located between the first opening 32 and the receiving hole 20. The first opening 32 may have a larger area than the second opening 34, and thus a step 2401 may be formed in the support member 240. The adhesive member 260 may be seated on the step 2401 and may be located in the first opening 32. When the support member 240 is viewed from above (e.g., when the support member 240 is viewed in a second direction 2 perpendicular to the first direction 1), the adhesive member 260 may have an annular shape in which a hollow corresponding to the second opening 34 is formed and that overlaps the step 2401. The ventilation member 250 disposed on the adhesive member 260 may be at least partially accommodated in the first opening 32. In this case, the ventilation member 250 may have substantially the same area and shape as the first opening 32. In an embodiment of the disclosure, the ventilation member 250 may be accommodated in the first opening 32 so as to extend without a step with the support member 240 (or, the first surface 240A of the support member 240), but is not limited thereto. In another embodiment of the disclosure, the ventilation member 250 may protrude outside the first opening 32 of the support member 240.

In another embodiment of the disclosure, unlike those illustrated in the drawings, the first opening 32 and the second opening 34 of the through-hole 30 may have the same area. In this case, the ventilation member 250 may have a larger area than the through-hole 30 and may cover the through-hole 30 from outside the through-hole 30.

In an embodiment of the disclosure, although the ventilation member 250 is illustrated as being disposed in the first opening 32 of the support member 240 and adjacent to the inner space 10, the ventilation member 250 is not limited thereto, and various design changes can be made. For example, the ventilation member 250 may be disposed on the support member 240 so as to be adjacent to the receiving hole 20. In other words, although the one side of the through-hole 30 adjacent to the inner space 10 is illustrated as being closed by the ventilation member 250, unlike that illustrated in the drawings, the ventilation member 250 may close an opposite side of the through-hole 30 adjacent to the receiving hole 20. In this case, the areas of the first opening 32 and the second opening 34 may be opposite to those illustrated in the drawings, and the ventilation member 250 may be accommodated in the second opening 34. Alternatively, the ventilation member 250 may be disposed on the second surface 240B of the support member 240 to cover the through-hole 30 from outside the through-hole 30.

In an embodiment of the disclosure, the ventilation member 250 may pass air and may block foreign matter (e.g., moisture and dust). In an embodiment of the disclosure, the ventilation member 250 may include a membrane through which a specific material is selectively permeable. For example, the ventilation member 250 may include an expanded polymerized tetrafluoroethylene (ePTFE) membrane formed by expanding polymerized tetrafluoroethylene (PTFE). However, the disclosure is not limited thereto, and to allow the ventilation member 250 to selectively transmit only air, various structures and/or materials applicable by those skilled in the art may be used.

In an embodiment of the disclosure, the inner space 10 of the housing 210 and an external environment may remain the same through the ventilation member 250 disposed between the inner space 10 and the receiving hole 20. For example, the inner space 10 may be fluidically connected with the through-hole 30 and the receiving hole 20 through the ventilation member 250, and the receiving hole 20 may be fluidically connected with the external environment. Since air circulates between the inner space 10 of the housing 210 and the external environment through the ventilation member 250, environments (e.g., pressures) inside/outside the electronic device 201 may remain in equilibrium.

In an embodiment of the disclosure, through the ventilation member 250, introduction of foreign matter into the inner space 10 of the housing 210 may be prevented.

In an embodiment of the disclosure, the through-hole 30 may be formed in the receiving hole 20 of the support member 240 without limitations of position, shape, and area.
