Description

Technical Field

[0001] The present disclosure relates to an electronic device including a physical button structure. Background Art

[0002] The electronic device may adopt such a structure in which various electronic components are arranged in a housing and a display is arranged on one surface of the housing. The electronic device may include a structure for preventing electronic components arranged in the electronic device from being damaged due to the introduction of moisture or water.

[0003] The above information is presented as background information only to assist with understanding the present disclosure. No determination has been made, and no assertion is made, as to whether any of the above may be used as prior art with respect to the present disclosure. Summary of the invention

[0004] Technical issues

[0005] For example, the power key or volume key corresponding to the side key has a simple key shape exposed to the outside and a small key width, so many flanges are applied to prevent the introduction of moisture or water. At the same time, in the case of setting the fingerprint key in the traditional side key shape, the size of the flange corresponding to the fingerprint key (including the click key) can be large enough to provide a water-inflow delay structure for the fingerprint key, thereby damaging the design or the appearance of the fingerprint key, while in the case of maintaining the design of setting the fingerprint key on the side surface, due to the limited size of the flange, the water-inflow delay time will become shorter, so it may be difficult to prevent the introduction of moisture or water. In the external assembly key structure, the fingerprint key must be connected to the PCB through a connection channel called FPCB. However, in the case of adopting the above-mentioned moisture-proof or water-proof structure, it may be difficult to assemble the fingerprint key from the outside of the electronic device. In addition, after the device assembly process, considering the additional defects in the fingerprint key itself, a verification process must be performed separately, and due to the high defect rate, the burden of replacing parts may be increased.

The third frame 160c may be disposed on a front surface on which a display 150 is arranged. The third frame 160c may be disposed on an edge surrounding the opposite side (e.g., the right side based on the illustrated drawings) of the display 150. The second housing 106b may be disposed on the rear side of the second housing 120. The fourth frame 160d may support the second housing 106b on the rear side of the second housing 120. According to various embodiments, the third frame 160c, the second housing 106b, and the fourth frame 160d may be integrated into one entity in the second housing 120. The second housing 106b may include an opening area in which an auxiliary display 180 smaller than the display 150 is disposed. In addition, a sensor 190 may be disposed on one side of the second housing 106b. The sensor 190 may include, for example, at least one of an illumination sensor, an iris sensor, and a proximity sensor.

[0034] The front camera 140 may be provided on one side provided on the front surface of the display 150. For example, based on the illustrated drawings, the front camera 140 may be provided on the upper right side of the display 150. Additionally or alternatively, other sensors (e.g., an iris sensor, a proximity sensor, and an illumination sensor) may be provided in the area in which the front camera 140 is provided.

[0035] Connectors 111, 112, and 121 including USB connectors or micro USB connectors may be provided on the upper and lower surfaces of the housing 160. In addition, an earphone hole for connecting an earphone jack may be provided on the upper or lower surface of the housing 160.

[0036] One or more physical button structures 200 may be provided on at least one of the left and right surfaces of the housing 160. The physical button structure 200 may include a physical button, which may be, for example, a volume button or a power button. According to various embodiments, at least one physical button structure 115, 125, 126, or 127 in the physical button structure 200 may include a fingerprint sensing button capable of sensing a fingerprint. For example, the first physical button structure 115 may be a button capable of sensing a fingerprint, or the second physical button structure 127 may be a button capable of sensing a fingerprint. The physical button structure 200 capable of sensing a fingerprint may be configured to further include other input functions (e.g., a power button function, a volume adjustment function, a camera shutter function, a pressure detection function, etc.), as well as a fingerprint sensing function.

[0037] Figure 2 is a view showing an example of an area where a physical button is provided in a structure of an electronic device according to various embodiments.

[0038] Reference Figure 2 , state 201 shows a state in which the button hole 169 formed on the side of the housing 160 and the physical button module 210 installed in the button hole 169 are separated from each other.

[0039] The button hole 169 may be formed through the side wall of the housing 160. The button hole 169 may have a size and shape corresponding to a portion of the physical button module 210 so that the physical button module 210 is installed in the button 169. For example, the button hole 169 may be formed in an oval shape or a rectangular shape with rounded corners.

[0040] The physical button structure 200 may include a physical button module 210 , a supporting bracket 280 , and a waterproof bracket 290 .

[0041] The physical button module 210 may include a physical button 211 and a fingerprint sensor module 212. The physical button 211 may include a contact portion 211a, a support portion 211b, and a dome key 211c. The contact portion 211a and the support portion 211b may be formed in a stepped shape. At least a portion of the contact portion 211a may be exposed to the outside through the button hole 169 so that an external object contacts the contact portion 211a. The support portion 211b may support the physical button module 210 to prevent the physical button module 210 from being separated from the housing 160. The contact portion 211a may be formed in a shape similar to the button hole 169, or may be formed to be smaller than the button hole 169. The contact portion 211a may be installed in the button hole 169. The support portion 211b may be provided at one end of the contact portion 211a, and at least a portion of the support portion 211b may be formed to be larger than the size of the button hole 169. The support portion 211b can be used to support the physical button module 210 to prevent the physical button module 210 from being separated from the button hole 169 to the outside. The contact portion 211a can also protrude beyond the support portion 211b, so that the physical button module 210 can have a cross-section in the shape of a hat. The dome key 211c can be provided on the rear surface of the support portion 211b, and can be restored after being deformed by pressing the physical button 211. The dome key 211c can include, for example, contact points separated from each other by a predetermined gap. When the two contact points are brought into contact with each other by pressing the physical button 211, the dome key 211c can send a corresponding signal to a designated part (e.g., a sensor circuit 212d). At least a portion of the contact portion 211a can be formed to be transparent so that a sensor provided in the physical button 211 senses a fingerprint, or can be formed of a material through which at least a portion of the light emitted by the sensor can sense the fingerprint passing.

[0042] The fingerprint sensor module 212 may include a sensor 212a, a sensor substrate 212b, a wiring or FPCB 212c, and a sensor circuit 212d. At least a portion of the sensor 212a may be disposed in the contact portion 211a or the support portion 211b. The sensor substrate 212b may be electrically connected to the sensor 212a. The wiring or FPCB 212c may be electrically connected to the sensor substrate 212b. The sensor circuit 212d may be electrically connected to the FPCB 212c, and fingerprint sensing may be controlled by the sensor 212a and the sensor substrate 212b. At least a portion of the sensor 212a, the sensor substrate 212b, and the FPCB 212c may be disposed in an area adjacent to the button hole 169 inside the housing 160 (e.g., an area sealed by the waterproof bracket 290). The sensor circuit 212d may be disposed in a designated area inside the housing 160, the specific area being disposed (or positioned) outside the area sealed by the waterproof bracket 290.

[0043] State 203 shows a state in which the physical button module 210 is inserted into the button hole 169 formed on the side of the housing 160. The contact portion 211a of the physical button module 210 may be mounted in the button hole 169, and the support portion 211b may be disposed inside the housing 160. The sensor circuit 212d of the physical button module 210 may be fixedly mounted on a mounting area formed on the side of the housing 160, and may be electrically connected to the sensor substrate 212b and the sensor 212a disposed inside the contact portion 211a through the FPCB 212c.

[0044] State 205 shows a state in which a support bracket 280 supporting the physical button module 210 is provided. The support bracket 280 can support the physical button module 210. The support bracket 280 can have elasticity so that the support bracket 280 is deformed while the physical button module 210 is subjected to external pressure, and then returns to position the physical button module 210 in the original position. The support bracket 280 can be, for example, disposed behind the physical button module 210, and at least a portion of the support bracket 280 can be fixed to the housing 160. The support bracket 280 can have a predetermined length along the side wall of the housing 160. The opposite edges of the support bracket 280 can be formed in a curved shape so that the opposite edges have a predetermined elasticity when being fixed to the bottom of the housing 160. The middle part of the support bracket 280 can apply elastic force to support the physical button module 210 and make the physical button module 210 in close contact with the button hole 169. For example, the support member 281 can be disposed on one side of the support bracket 280. Support member 281 may be provided on the rear surface of dome key 211c and may function as a shock absorber to prevent damage to dome key 211c when dome key 211c is pressed and deformed. Support member 281 may be formed as a component of support bracket 280 or may be removed according to design changes.

[0045] State 207 shows a state in which the button hole 169, at least a portion of the physical button module 210, and the waterproof bracket 290 covering the support bracket 280 are set to have a waterproof function. The waterproof bracket 290 may be formed to have a predetermined length along the side wall of the housing 160. The waterproof bracket 290 may be formed in an "L" shape so as to be in close contact with the angled corner of the housing 160 (e.g., a corner having an angle formed by the bottom and side wall of the housing 160). For example, the waterproof bracket 290 may include a side wall bracket portion in close contact with a first surface of the housing 160 (e.g., a side wall surface of the housing 160) and a bottom bracket portion in close contact with a second surface of the housing 160 (e.g., the bottom of the housing 160). An adhesive member for preventing fluid from flowing in may be provided at the edge of the waterproof bracket 290. The adhesive member may be used to firmly attach the waterproof bracket 290 to the housing 160. The sensor circuit 212 d connected to the FPCB 212 c may be disposed at the bottom of the housing 160 to be disposed (or positioned) outside a position where the waterproof bracket 290 is securely attached to the housing 160 .

[0046] As described above, the physical button structure 200 according to the embodiment can be assembled by first inserting the physical button module 210 in a direction from the inside to the outside of the housing 160. At this time, the physical button 211 can be temporarily fixed to the outside of the housing 160 by a temporary fixing tape. For example, at least a portion of the temporary fixing tape can be set on the button hole 169, and the physical button 211 installed in the button hole 169 can be temporarily fixed. In addition, after the support bracket 280 in the housing 160 fixes the inward push of the physical button module 210, the temporary fixing tape can be removed. A waterproof bracket 290 for waterproofing (or water inlet delay) can be assembled inside the housing 160. The waterproof bracket 290 can be additionally anchored to one side of the housing 160 by using a hook or screw other than the adhesive member 291.

[0047] The physical button structure 200 may include a fingerprint sensor module 212 disposed therein, and may support a click function (e.g., a function according to the operation of the dome key 211c included in the physical button 211) by a user's pressing. In the case where water is introduced from the outside, since the waterproof bracket 290 is disposed in three directions within the housing 160, the physical button structure 200 may support a water ingress delay function or a waterproof function in multiple directions. For example, the waterproof bracket 290 may simultaneously support a water ingress delay for a first surface of the housing 160 in a direction from the inside of the housing 160 toward the side wall and a waterproof or water ingress delay for a second surface of the housing 160 in a direction from the inside of the housing 160 toward the bottom.

[0048] As described above, the physical button structure 200 of the present disclosure can be configured to simultaneously cover the first surface of the shell 160 and the second surface of the shell 160, wherein the second surface of the shell 160 forms an angle with the first surface of the shell 160, thereby supporting the water release function of multiple surfaces, and can disperse the pressure of the introduced fluid, thereby providing a more robust waterproof (or water inlet delay) function. Therefore, even under higher water pressure, the ability of the physical button structure 200 to disperse fluid pressure can also support the provision of a waterproof function (or a water inlet delay function). In addition, the electronic device 100 can use multiple surfaces to provide a waterproof structure or a water inlet delay structure. Therefore, the thickness of the electronic device 100 can be implemented to be thinner, and the internal area adjacent to the button hole 169 and provided with the physical button structure 200 can be fully ensured, thereby facilitating the installation of various structures (for example, sensor circuits or other components).

[0049] In addition, the sensor 212a and the sensor substrate 212b of the fingerprint sensor module 212 can be set in the physical button module 210, so the physical button structure 200 can solve the problem of the fingerprint sensor module 212 pouring out of the housing 160 through the button hole 169. In addition, the part where the fluid introduced from the outside is transferred to the sensor circuit 212d through the FPCB 212c can be sealed by using a waterproof tape or a dispensing adhesive, so the physical button structure 200 of the present disclosure can prevent the fluid from diffusing to the sensor circuit 212d.

[0050] Figure 3 is a view showing an example of a physical button structure of a housing according to various embodiments.

[0051] Reference Figure 3 , state 301 shows an enlargement of a partial area (e.g., an area of ​​the physical button structure 200) of the housing 160 of the electronic device 100. The partial area of ​​the housing 160 may include a button hole 169 and an area of ​​the physical button structure 200 disposed in the button hole 169. State 301 shows a state in which the waterproof bracket 290 is set to cover the support bracket 280, wherein the physical button structure 200 is installed in the button hole 169. State 303 shows a cross section taken along line A-A' in this state 301, and state 305 shows a cross section taken along line BB'.

[0052] Referring to state 303, the first frame 160a may be disposed on one side of the housing 160 (e.g., the front surface on which the display 150 is disposed), and may be disposed to surround at least a portion of the edge of the display 150, and the waterproof bracket 290 may be attached to the edge of the interior of the housing 160 by an adhesive member 291. The waterproof bracket 290 may have an "L"-shaped cross section. The waterproof bracket 290 may include a first bracket 290a disposed parallel to the side wall of the housing 160 and a second bracket 290b disposed on the bottom of the housing 160 and forming a predetermined angle with the first bracket 290a. In the illustrated drawings, the angle formed by the first bracket 290a and the second bracket 290b is shown as 90 degrees or an angle close thereto. However, the present disclosure is not limited thereto. That is, the angle between the first bracket 290a and the second bracket 290b may be less than or greater than 90 degrees (e.g., in the range of 30 to 150 degrees). The edge of the interior of the housing 160 may be formed as a step shape lower than the surrounding area by a predetermined depth, so that the waterproof bracket 290 is mounted on the edge of the interior of the housing 160. According to an embodiment, the waterproof bracket 290 may be used to support the support bracket 280 and the physical button module 210 to prevent the support bracket 280 and the physical button module 210 from being detached from the area adjacent to the button hole 169 of the housing 160 to the outside.

[0053] A track groove 310 formed concavely may be formed on one side of the rear surface of the housing 160 (e.g., a surface opposite to the front surface on which the display 150 is provided, i.e., an upper surface when viewed based on the illustrated view) so that a rear glass or film is provided therein. At least a portion of an edge of the rear glass may be provided in the track groove 310. An adhesive member may be additionally provided in at least a portion of the region inside the track groove 310 to fix the rear glass.

[0054] The adhesive member 291 may be provided between the waterproof bracket 290 and the edge of the inside of the housing 160 (or in the installation area inside the housing 160). The adhesive member 291 may be formed to be similar in shape to the waterproof bracket 290 or smaller than the waterproof bracket 290. The adhesive member 291 may be formed in a shape corresponding to the inner shape of the waterproof bracket 290. For example, a cushion or a waterproof tape for preventing water from flowing in may be used as the adhesive member 291, and thus the thickness of the adhesive member 291 and the area where the adhesive member 291 is provided may be adjusted in various ways. The adhesive member 291 may be provided below the waterproof bracket 290, and may form a closed curve to seal the lower area of ​​the waterproof bracket 290.

[0055] Referring to state 305, a button hole 169 may be formed in the housing 160, and the housing 160 may include a hole frame 160_1 disposed to surround the button hole 169. The hole frame 160_1 may include a portion of the housing 160 disposed in a direction in which the rear glass is disposed and a portion of the housing 160 disposed in a direction in which the display 150 is disposed. At least a portion of the first frame 160a may be mounted on the hole frame 160_1. At least a portion of the contact portion 211a of the physical button structure 200 may be exposed to the outside through the button hole 169, and at least a portion of the support portion 211b connected to the contact portion 211a may be mounted in the housing 160 in which the button hole 169 is formed. The fingerprint sensor module 212 may be disposed in the support portion 211b (or in the support portion including at least a portion of the area of ​​the contact portion 211a).

[0056] The fingerprint sensor module 212 may include a sensor 212a, a sensor substrate 212b, an FPCB 212c, and a sensor circuit 212d. The sensor 212a may send and receive signals for sensing fingerprints. The sensor substrate 212b may support the sensor 212a and may be electrically connected to the sensor 212a. The sensor substrate 212b may be connected to a wiring or FPCB 212c. The FPCB 212c may be electrically connected to the sensor circuit 212d. According to an embodiment, one side of the FPCB 212c may be disposed on one side of the dome key 211c. The dome key 211c may be electrically connected to the sensor substrate 212b. Therefore, the FPCB 212c may be connected to the dome key 211c when connected to the sensor substrate 212b through the dome key 211c, and may transmit a signal to the sensor circuit 212d according to the operation of the sensor 212a and the dome key 211c. The dome key 211c may be disposed behind the fingerprint sensor module 212, and a support member 281 supporting the dome key 211c may be disposed behind the dome key 211c.
