1. Technical Field
The present disclosure generally relates to an electronic device that is worn on a human body.
2. Description of the Related Art
Methods for a user to carry a portable electronic device include carrying a the device in the user's pocket or bag, holding the device in the user's hand, or carrying the device by wearing it on a predetermined location of a human body. A wearable device can be worn on various parts of the human body and used.
Wearable devices may be worn on the human body in various ways as follows:
1. A wearable device may be worn on a human body such as a wrist like a watch or band;
2. A strap-type wearable device may be worn on a human body like a necklace; and
3. A glasses-type wearable device may be worn on user's face;
4. A clip-type wearable device may be worn by being clipped to a human body, clothing, or user's belongs; and
5. There are many other methods for attaching a wearable device to a human body, belongs, or an accessory directly or indirectly.
In addition, a wearable device may include a body and a wearing part (a strap or band), and may be worn on various parts of a human body according to a configuration of the wearing part. The wearable device may be one of the following structures:
1. a structure in which the body and the wearing part are integrally formed with each other and inseparable from each other;
2. a structure in which the body and the wearing part are separable from each other and thus are changeable.
Currently available wearable devices have several deficiencies. For example, the body of the wearable device is mostly designed regardless of design aspects and the exterior of the body and the inner wearing part are mostly formed according to the same flat/curved shape or a basic design shape.
Such a shape is not appropriate to the wearable device and acts as a factor delimiting functions and design of the wearable device.
In addition, where the wearable device has the body and the wearing part are integrally formed with each other, the body and the wearing part are not changeable and thus there is a limitation to providing various designs and customized functions. Furthermore, if the body and the wearing part are separable from each other and changeable, it would be possible to customize the wearable device according to a user's taste in view of an exterior design or function. However, there is a contradiction between the degree of fastening and convenience in removing the body, and deterioration of the wearing part caused by an individual using pattern or frequent replacement may cause a serious problem in the fixing stability of the device.

The curved body 10 may be configured to gradually become thinner from the center toward the opposite sides thereof. The curved body 10 may be relatively thick on the center and may gradually become thinner toward the sides. In addition, although the rear surface 121 has the second curvature in the above-described embodiment, the rear surface 121 may be a substantially flat surface without a curvature.
The exterior structure of the curved body 10 can ergonomically improve a sensation that a user may feel when wearing the device and can improve compatibility in response to various consumers' wrists. The curved body 10 may be provided with the curved display 11 on the front surface 120 and may include a skin contact surface provided with a sensor 13 (an interface of the sensor is seen in FIG. 4) on the rear surface 121, so that the degree of freedom of the exterior design can be maximized and optimal sensor performance can be provided to all of the users. In particular, the rear surface 121 of the curved body 10, which is the skin contact surface, may be configured as a nearly flat surface in comparison to the free shape of the exterior design of the curved body 10, and may have the sensor (s) arranged thereon to respond to all of the various body curvatures appropriately.
In addition, the curved body housing 12 in the present embodiment may have a sensor interface (SW) formed on the rear surface thereof which is in close contact with user's skin, and has the display, a touch input part, a button key, a charging terminal, and an information interface formed on a surface other than the skin contact surface (bottom surface of the body housing).
The display 11 is formed in a shape reflecting a curved shape of the human body and may be formed in a flat shape (Liquid Crystal Display (LCD), Organic Light Emitting Diode (OLED)) or a curved shape (flexible OLED). Although the display 11 is provided in the present embodiment is described as being curved, the display 11 may instead be configured as a flat display.
A seating recess 13 may be formed on the side surface of the curved body housing 12. The seating recess 13 extends along the side surface 122 of the curved body housing 12. An exterior side surface of the side surfaces of the curved body housing 12 that is seen by the user has a curvature. The seating recess 13 has the same curvature as the first curvature of the front surface 120 of the curved body housing 12. However, the curvature of the seating recess 13 may be the same as the first curvature, but may be larger or smaller than the first curvature since men and woman have various wrist curvatures. In FIG. 6, the curvature of the seating recess 13 is the same as the first curvature. As will be described, the seating recess 13 includes a top surface curvature and a bottom surface curvature in some section. The bottom surface curvature may vary to respond to various wrist curvatures. The top surface curvature and the bottom surface curvature of the seating recess 13 may vary in a boundary area with the body according to a wrist curvature of a user who wears the wearable device.
In the above-described embodiment, the seating recess 13 has a curvature, and a top surface 33a and a bottom surface 33b of the seating recess 13 have the same curvature. The seating recess 13 formed on the outside surface of the body housing 12 may extend to have the curvature with the same width and the same thickness and thus the top surface 33a and the bottom surface 33b of the seating recess 13 have the same curvature as the first curvature.
FIG. 7 is a section view showing arrangement of electronic parts provided in the curved body 10 according to various embodiments of the present disclosure. FIG. 8 is a side view showing the curved body 10 according to various embodiments of the present disclosure. FIG. 9 is a side view showing arrangement of substrates and electronic parts provided in the curved body 10 according to various embodiments of the present disclosure.
Arrangement of electronic parts mounted in the curved body 10 will be explained with reference to FIGS. 7 to 9. In the present embodiment, a curved battery 14 is mounted under the display 11 in a layered structure, such that the curved body 10 gradually becomes thinner from the center toward the opposite sides. That is, the curved body 10 has the curved display 11, the curved battery 14, and substrates P1-P3 layered therein one on another.
In the present embodiment, the curved body 10 may be configured such that an exterior surface which is easily seen with user's eyes (for example, a display screen) and a contact surface which is worn on a human body and is in close contact with a skin (a rear surface of the body housing) have different curvatures, and has an optimum layered structure of electronic parts mounted therein. The curved body 10 according to the present embodiment is provided with the display 11 having the highest degree of freedom of manufacturing a curved surface on the exterior surface having the largest curvature, and has the battery 14 installed inside the display 11. In this case, the battery 14 has a curved shape and has the same curvature as the first curvature. The battery 14 may be mounted with reference to the center of the curved display 11, and facilitates providing or guaranteeing mounting spaces that are formed at both ends of the battery. The mounting spaces may be used as spaces for compensating for reduction in the curvature of the skin contact surface (rear surface). The above-described mounting structure results in reduction in the thickness at the both ends in comparison to the center of the curved body 10, thereby achieving a good design and minimizing a step height which may be generated with respect to the wearing part 20.
Hereinafter, the arrangement of various electronic parts and substrates mounted in the curved body 10 will be explained.
The curved battery 14, a plurality of electronic parts s, m, and c and a plurality of substrates P1, P2, and P3 are arranged in the curved body 10. The curved display 11, the curved battery 14, and the plurality of substrates P1, P2, and P3 are arranged in the curved body 10 in a vertically layered structure. In particular, the battery 14 according to the present embodiment is disposed on an intermediate layer between the curved display 11 and the substrate P1. This structure is to serve as a safety device for preventing a low temperature burn caused by heat emitted from the battery and minimizing any damage to the user caused by explosion of the battery, and may be a vertically layered structure.
The curved body 10 includes the curved body housing 12 and an inner bracket 15. The curved body 10 forms a single body by coupling the inner bracket 15 to the curved body housing 12. The body housing 12 and the inner bracket 15 may be independently manufactured and coupled to each other. However, the inner bracket 15 may be included in the body housing 12. The curved display 11 may be attached to the front surface of the body housing 12 by an adhesive tape (double-sided waterproof tape), and the inner bracket 15 may be received in and fixed to the body housing 12. The inner bracket 15 may receive the curved battery which is layered under the curved display 11 and one or the plurality of substrates P1, P2, and P4 arranged between the front surface 120 and the rear surface 121 of the body housing 12.
In addition, according to the present embodiment, the plurality of substrates P1, P2, and P4 may be arranged in the inner space of the body housing 12, specifically, in the inner bracket 15. In this case, a segmental (articular) structure substrate may be applied, thereby improving efficiency of mounting of the electronic parts. The above-mentioned segmental structure substrate appropriately provides rigid substrates P1, P2, and P3 and flexible substrates F1 and F2 to sections where the substrates are needed, thereby smoothly implementing a curved design, and may have the electronic parts directly arranged in respective segmental sections separately according to a required condition, thereby improving performance of the electronic device. For example, a part vulnerable to a noise and a noise generating part may be arranged on separate substrates and a part vulnerable to a shock and a shock generating part may be arranged on separate substrates. Such arrangement of the electronic parts may naturally separate a noise generating section and a noise sensitive section from each other and may block a vibration shock transmitted through the rigid substrates P1, P2, and P3 in the section of the flexible substrates F1 and F2, thereby achieving a design for optimizing electrical performance of the electronic device and durability. In the future, a curved rigid or flexible substrate will be applicable instead of the above-described rigid substrate thanks to the technology development. In the above-described substrate segmental structure, a non-contact sensor such as a gyro sensor, an acceleration sensor, and/or other optical sensors may be further provided in addition to the basic parts related to communication or input and output.
The plurality of substrates may include the plurality of rigid substrates (for example, Printed Circuit Boards (PCBs)) and the plurality of flexible substrates (PCBs), and the rigid substrates P1, P2, and P3 are substrates where various electronic parts are mounted and the electronic parts may be mounted on both the top surface and the bottom surface of each of the rigid substrates P1, P2, and P3. In FIG. 7, three rigid substrates are mounted and are referred to as a first substrate P1, a second substrate P2, and a third substrate P3. The first substrate P1 is disposed in the center, the second substrate P2 is disposed on the right of the first substrate P1, and the third substrate P3 is disposed on the left of the first substrate P1. A substrate connecting the first substrate P1 and the second substrate P2 is referred to as a first flexible substrate F1, and a substrate connecting the first substrate P1 and the third substrate P3 is referred to as a second flexible substrate F2. The first, second, and third substrates P1, P2, and P3 and the first and second flexible substrates F1 and F2 are connected with one another, thereby configuring the segmental substrate.
In addition, when various electronic parts are arranged on the first, second, and third substrates P1, P2, and P3, parts vulnerable to a noise and noise generating parts may be arranged on separate substrates, and parts vulnerable to a shock and shock generating parts may be arranged on separate substrates.
For example, out of the electronic parts mounted on the substrates, a part vulnerable to a noise (PAM) and a noise generating part (AP, CP) may be separately arranged on the first and second rigid substrates P1 and P2, respectively, and a part vulnerable to a shock (a BGA part such as AP and CP) and a shock generating part (for example, a vibrator or a vibration motor) may be separately mounted on the second and third substrates P2 and P3, respectively. Such inner arrangement of the electronic parts can naturally separate a noise generating section and a noise sensitive section from each other, and block a vibration shock transmitted through the rigid substrates in the flexible substrate section, thereby achieving a design for optimizing electrical performance of the electronic device and durability.
In addition, at least one of the rigid substrates disposed on the rear surface 121 of the body housing 12 may be horizontally placed or may be slantingly placed. The first substrate P1 is disposed in the center and has a first sensor (s) (which is exposed from the rear surface of the body housing and is in close contact with a skin of a human body to acquire a variety of information on the human body) disposed thereon. Therefore, the first substrate P1 should be placed horizontally along with the first sensor (s). The first sensor (s) may be exposed from the rear surface of the body housing and may be disposed on a location where the first sensor (s) is in the closest contact with the skin. That is, the first sensor (s) may be horizontally disposed substantially on the center of the rear surface 121 of the body housing. The first sensor (s) may be mounted on the rear surface of the first substrate P1 and a sensor interface (sensor interface window) may further be provided. In addition, even when a PCB is mounted slantingly with respect to the exterior surface of the housing, a balance can be maintained by using an interposer between the PCB and the first sensor. The first sensor (s) may have the sensor interface window exposed from the rear surface 121 of the body and may be horizontally disposed. The sensor interface window may be provided on the sensor or may be attached to the exterior of the body housing. For example, the first sensor (s) may be a Heart Rate Monitor (HRM) or a vein sensor which can acquire information from user's skin or body.
Additionally, the first sensor (s) which is exposed from the rear surface 121 of the body housing may further include a protrusion 125 protruding toward the rear surface, while enclosing the circumference of the first sensor (s) with a predetermined thickness. The protrusion 125 may make the sensor interface, for example, the sensor interface window (SW), exposed and more brought into close contact with the skin. The sensor interface (SW) is located on a flat surface of the rear surface 121 and the flat surface is located on the center.
In the present embodiment, even when the segmental structure substrates are used, at least a horizontal and flat part seating plane part (an area where the first substrate is mounted in the body housing) should be provided to mount electronic parts, and the plane part requires a plane seating structure for performing a function such as a function of a sensor. In the present embodiment, when a space guaranteed at the both ends of the curved battery 14 is used as a mounting area, a loss in the mounting space caused by the substrate being mounted on the plane can be offset. In particular, when a relatively thick part such as a vibrator (m) or a connector is placed, an inevitable increase in the total thickness of the curved body can be prevented. Although not shown, various mechanism configurations such as a sub battery or a hook assembly can be mounted in the guaranteed space.
In the curved body 10 according to the present embodiment, the third substrate P3 is disposed between the lower side of the display 11 and one side area of the battery 14 (Y-axis direction), and the motor (m) is disposed on the third substrate P3 and the charging terminal (c) is disposed on the first substrate P1. The motor (m) is horizontally disposed in parallel with the battery 14 and the charging terminal (c) is horizontally disposed in parallel with the battery 14. The motor (m) is disposed on the top surface of the third substrate P3 and the charging terminal (c) is disposed on the bottom surface of the first substrate P1. The charging terminal (c) is exposed from the rear surface 121 of the body housing. Since the motor (m) is a relatively thick part or a part of a great volume, it is advantageous to dispose the motor (m) on the second substrate P2 or the third substrate P3 in view of the efficiency of mounting.
As other input devices mounted in the substrates, an electric switch interface using a touch sensor, a pressure sensor, a temperature sensor, and the like, and a physical switch interface such as a tact dome key may be disposed on one surface of the body housing, on which the user can manipulate. Charging and interface terminals may further be disposed on a location of the front surface or the rear surface of the body housing that does not deface the exterior. In the present embodiment, the charging terminal (c) is disposed on the rear surface 121 of the body housing. According to the present embodiment, the surface that does not deface the exterior of the wearable device may be the rear surface of the body housing, that is, the surface which is in contact with the human body.
Hereinafter, the configuration of the display 11 disposed on the front surface of the curved body 10 will be explained.
FIG. 10 is an exploded perspective view showing the configuration of the curved display 11 provided in the curved body according to various embodiments. Referring to FIG. 10, the display 11 applies a flexible LCD 110 having a curvature and a curved window 112 having the same curvature as that of the flexible LCD 110 to achieve a curved design having a curvature. The curved window 112 includes a rigid or flexible layer.
The display 11 has a shape reflecting a curved part of a human body and may include a curved LCD (flexible OLED). The design of the front surface of the body can be achieved by the curved surface of the LCD or the curved window 112 presenting a curved surface. The display 111 may further include a sensor for detecting a touch, pressure, or temperature in addition to the curved flexible LCD 110, thereby providing a Perceptual User Interface (PUI) optimized to use of various user interface (UIs). In addition, the window 112 ma provide a layer made of a ceramic material such as glass and a sheet material such as PET, PC, and the like to protect the surface.
FIG. 11 is a perspective view showing the curved battery 14 provided in the curved body according to various embodiments of the present disclosure. Referring to FIG. 11, the battery 14 according to an embodiment of the present disclosure applies a curved battery pack, thereby improving efficiency of mounting of the electronic parts in the body. The curved battery 14 may be mounted in a bent state. This is a factor that is optimized to realize the exterior design of the curved body and mount an HW part of the wearable electronic device worn on the human body.
The battery 14 may be manufactured in a bent shape and configured to have a predetermined curvature. The front surface and the rear surface of the battery 14 each have a curvature. The curvature of the battery 14 may be the same as the curvature of the display and thus the battery 14 may be disposed to face the rear surface of the display. A mounting space may be formed on the center of the rear surface of the battery 14 and can be utilized effectively by mounting a hardware electronic part therein. The battery 14 may not have the same curvature as that of the display. In addition, although the battery 14 may be disposed between the display and the substrate, the battery 14 may be configured in a flat shape and may be disposed on the bottom surface of the substrate.
Referring back to FIG. 7, a separate layer part 142 may be added between the curved battery 14 and the first substrate P1 to prevent breakage of parts of the first substrate P1 and the battery caused by volume expansion of the curved battery 14. The layer part 142 stops volume expansion of the battery 14. The layer part 142 may act as a physical support structure or a buffering section for the curved battery 14 and the first substrate P1, and may be provided in the form of a barrier for preventing a battery liquid from leaking to the lower side. The layer part 142 may be provided as a conductive or metal piece or an injection molding piece.
FIG. 12 is a plan view showing the front surface 120 of the body housing according to an embodiment of the present disclosure. In the present embodiment, an assembly structure of the body housing 12 without a screw boss is provided. The inner bracket in which electronic parts are modularized and the body housing 12 may be fixed by a hook and the display window and the front surface 120 of the body housing may be assembled with each other by using a waterproof tape. Therefore, the inner mounting space can be maximized and the waterproof function can be maximized by excluding a screw boss. Reference numeral 120a indicates a surface to which the waterproof tape is attached.
FIG. 13 is a partial cutaway perspective view showing the curved body prior to being mounted on the wearing part according to various embodiments of the present disclosure. Referring to FIG. 13, a body removable structure provided in the wearable device according to an embodiment of the present disclosure and a direction of removal will be explained. In the present embodiment, an undue bending operation may occur between the body 10 and the seating part 22 due to a shape characteristic of the bar type body 10 having a curvature and various characteristics of body shape of the user. In this case, a structure may be configured to provide a removal force according to a direction of the present embodiment needs to fix the longitudinal end of the body 10 more tightly. The size of the seating part is designed to be smaller than the longitudinal size of the body so that the side surface of the body can be hold relatively stronger by elasticity of the wearing part. In addition, a separate bending prevention protrusion structure may be added to a certain section of the seating part facing the body with respect to the section where an undue bending operation occurs when the wearable device is worn on the human body.
Referring to FIG. 13, the body 10, that is, the body housing 12, may be removable from the wearing part 20. The direction of removal may include a coupling direction (that is the relative direction that the body housing 12 and the wearing part 20 move to effect coupling) in which the body 10 moves from bottom to top and is coupled to the seating part 22, and a decoupling direction (that is the relative direction that the body housing 12 and the wearing part 20 move to effect decoupling) in which the body 10 is pushed down and is decoupled from the wearing part 20. The coupling direction refers to a direction in which the body coupled to the wearing part 20 is prevented or inhibited from being separated from the human body.
The curved body housing 12 may have a widthwise direction in which the width is gradually reduced from the rear surface or the center to the front surface, such that removal of the body housing 12 from the wearing part 20 may be accomplished by moving the body housing 12 and the wearing part 20 apart from each other in a first direction but not in a second direction that is opposite that of the first direction, thereby providing a first removal direction. The width W2 of the body housing 12 on the front surface in the widthwise direction (X-axis direction) is smaller than the width W1 on the center (including the rear surface) in the widthwise direction. The body housing 12 having the above-described shape should be moved from bottom to top with reference to the seating part to be coupled to the seating part. The side surface of the body housing includes a first part enclosing between the recess 13 and the front surface 120 and a second part enclosing a part between the recess 13 and the rear surface 121, and the width W2 of the first part is set to be smaller than the width W1 of the second part when viewed in a cross section of the body housing 12 cut perpendicularly to the first direction (Y-axis direction). The above-described structure provides the first removal direction.
In addition, the removal structure for coupling or decoupling the curved body housing 10 to or from the seating part 22 may be formed along the circumference of the opening provides a second direction of removal. The removal structure includes the seating recess 13 and the seating part 22. The seating recess 13 may extend along the circumference of the side surface 122 of the curved body housing and continuously extends with the same curvature as the first curvature. The seating part 22 may be tightly coupled to the seating recess 13 to fix the curved body housing 10 to the opening 21. The seating part 22 may be made of an elastic material and is elastically deformable according to whether the seating part 22 is coupled to the seating recess 13 or not, and the opening of the seating part is configured to be slightly smaller than the curved body housing so that the seating part is tightly coupled to the seating recess 13. In particular, the seating part 22 may be coupled to the seating recess formed along the outer circumference of the side surface of the side surfaces 122 of the curved body housing to have the same curvature as the first curvature.
The seating recess 13 may be provided with a first close contact surface including a first top surface 130, a first intermediate surface 131, and a first bottom surface 132. The seating recess 13 may be configured to have the horizontal width of the exterior corresponding to the first bottom surface 132 wider than the horizontal width of the exterior corresponding to the first top surface 130. The first top surface 130 may be configured to be horizontally flat or substantially horizontally flat, and the first bottom surface 132 may be configured to be horizontally flat or substantially horizontally flat.
In addition, the seating part 22 includes a second close contact surface including a second top surface 220, a second intermediate surface 221, and a second bottom surface 222 and which is in close contact with the first close contact surface. The second top surface 220 may be configured to be horizontally flat or substantially horizontally flat and the second bottom surface 222 may be configured to be horizontally flat or substantially horizontally flat. The seating part 22 is configured to have the horizontal width of the exterior corresponding to the second bottom surface 222 wider than the horizontal width of the exterior corresponding to the first top surface 220 such that removal may in accomplished by moving the body 10 relative to the seating part 22 in one direction but is inhibited in the opposite direction, thereby providing the second removal direction.
The second close contact surface of the seating part 22 is formed in a shape corresponding to the first close contact surface of the seating recess 13, so that the body can be safely coupled to the wearing part and safely decoupled from the wearing part when necessary. Such a removal structure can prevent unexpected removal caused by a wearing pressure when the user does physical activity (can prevent the body from being decoupled from the wearing part).
Hereinafter, a waterproof structure of a wearable device according to an embodiment of the present disclosure will be explained with reference to FIGS. 14 to 16. FIG. 14 is a partial cutaway perspective view showing a waterproof structure applied to a plurality of parts of the wearable device according to various embodiments of the present disclosure. FIG. 15 is a partial cutaway perspective view showing a waterproof structure applied to a side key of the wearable device according to various embodiments of the present disclosure. FIG. 16 is a partial cutaway perspective view showing a waterproof structure applied to a charging terminal of the wearable device according to various embodiments of the present disclosure. As shown in FIGS. 14 to 16, the wearable device according to the present embodiments applies a uni body structure by coupling the body housing and the battery bracket, thereby minimizing the number of waterproof points. The wearable device according to the present embodiments includes a plurality of waterproof structures. The waterproof structure of the wearable device according to the present embodiments is applied to a place where the curved window 112 is disposed, a place where the side key (k) is disposed, a place where the sensor (s) is disposed, and a place where the charging terminal (c) is disposed.
First, the waterproof structure for the curved window 112 mounted on the front surface 120 of the body housing applies a waterproof tape (T1). The curved window 112 is attached to an adhesive surface of the circumference of the front surface 120 to which the waterproof tape T is attached by using the waterproof tape T1. The waterproof tape T1 is a double-sided tape and has an upper surface attached to the curved window 112 and a lower surface attached to the adhesive surface 120a of the front surface (shown in FIG. 12). Water is prevented from entering the body housing 12 by the waterproof tape T1.
Secondly, the waterproof structure for the side key (k) disposed on the side surface 122 of the body housing applies a waterproof tape T2. The waterproof tape T2 may be a double-sided tape and may be provided to enclose the side key (k). One surface of the waterproof tape T2 may be attached to the inner surface of the body housing where the side key is disposed, and the other surface is attached to a silicon rubber, so that water is prevented or inhibited from entering by the waterproof tape T2. In addition, the side key (k) includes a silicon rubber for providing a restoring force when it is pressed, and a waterproof protrusion P is tightly arranged along the circumference of the silicon rubber (see FIG. 15) so that water is prevented from entering between the silicon rubber and the inner surface of the body housing. The silicon rubber prevents water from entering through the lower side by using the waterproof protrusion P and prevents water from entering the upper side by using the waterproof tape T2 placed on the lower side.
Thirdly, a waterproof structure using a waterproof tape T3 is applied to the sensor (s) disposed on the rear surface 121 of the body housing. The sensor (s) is provided with a sensor interface (sensor window) and the waterproof tape T3 is a double-sided tape and has one surface attached to the inner surface of the body housing and the other surface attached to the bottom surface of the sensor interface (sw). The waterproof tape T3 is attached along the lower circumference of the sensor interface (sw).
Fourthly, a waterproof structure is applied to the charging terminal (c) disposed on the rear surface 121 of the body housing. The waterproof structure for the charging terminal (c) may be achieved by fitting a high elastic waterproof part R made of rubber or silicon material into the charging terminal (c). The waterproof part R is disposed between the side surface of the charging terminal and the inner wall of the body housing to prevent water from entering the charging terminal. In addition, a waterproof tape P4 is attached between the body of the charging terminal and the inner surface of the body housing to prevent water from entering the body of the charging terminal (c). In addition to the waterproof tape, various kinds of adhesive such as a bond, silicon, and the like may be used as a waterproof member.
FIGS. 17A and B is a section view showing a boundary area A between the body and the wearing part according to various embodiments of the present disclosure. Referring to FIGS. 17A and B, the configuration of the wearing part 20 according to various embodiments of the present disclosure will be explained. The wearing part 20 includes a seating part and a band. When a user wears the wearable device on user's wrist, the wearing part 20 is subject to a pulling force in the boundary area A between the body 10 and the wearing part 20. In this state, there may be a gap between the body 10 and the wearing part 20 (the pulling force is concentrated) and the gap may deface the exterior. To prevent this problem, a coring section in the form of a cavity is provided on the inner surface of the end of the wearing part 20 in the boundary area, that is, on a certain section of a wearing surface. The end of the wearing surface is relatively thinner than the other parts by the coring section. Therefore, when the user wears the wearable device on the user's wrist, the wearing part, which is relatively thin, may be relatively more bent such that a gap is inhibited or prevented from being generated between the body 10 and the wearing part 20.
FIG. 18 is a view showing an example of an assembly order of the wearable device according to various embodiments of the present disclosure. An assembly process of the wearable device according to the present embodiment will be explained with reference to FIG. 18. Referring to FIG. 18, a battery bracket (inner bracket) for fixing electronic parts is further provided in the present embodiment. A structure by coupling the body housing and the battery bracket to each other is to guarantee assembly of a uni-body housing structure optimized to waterproofing. In addition, various electronic parts may be fixed to the battery bracket by assembling, attaching, fusing, riveting, screwing, and the like. The present embodiment may provide an assembly structure that excludes a screw boss. The battery bracket in which the electronic parts are modularized and the body housing are fixed by a hook and a gap between the curved window and the body housing is finished by a waterproof tape, so that the inner mounting space can be maximized and the waterproof performance can be maximized by excluding a screw boss. First, the battery is mounted in the battery bracket and a conductive or metal piece is fixed to the center of the rear surface of the battery. Next, a substrate assembly is assembled with the battery bracket and the display is fixed to the battery bracket. Finally, the body housing is assembled with the battery bracket assembly and a final assembly is completed.
FIG. 19 is a side view showing a wearable device according to various embodiments of the present disclosure, in which a body and a wearing part 40 is decoupled from each other. FIG. 20 is a side view showing the body 30 and the wearing part 40 which are coupled to each other according to various embodiments of the present disclosure. In explaining the configuration of the wearable device according to the present embodiment with reference to FIGS. 19 and 20, redundant explanation of the same elements as those of FIGS. 2 and 3 will be omitted and only differences will be explained.
In general, users' wrists have different curvatures when users wear wearable devices on their wrists. Since the respective curvatures of the users' wrists are different, a wearing sensation that each user can feel may be different. In particular, since woman's wrist is thinner than man's wrist, the wearable device cannot fit all of the users. However, since the wearable device according to the present embodiments has a structure in which the wearing part 40 is removable from the body 30 and the wearing part is changeable, users can select the wearing part to fit their respective body sizes.
The wearing part 40 of the wearable device according to the present embodiment of FIGS. 19 and 20 has a different curvature from the wrist curvature provided by the wearing part of the wearable device shown in FIGS. 2 and 3. The wearable device according to the present embodiment includes the wearing part 40 and the body 30 which can be coupled to or decoupled from the wearing part 40. The end of the wearing part 40 provides a varying curvature in the boundary area A where the body 30 and the wearing part 40 are coupled to each other, so that the wearable device can respond to various wrist curvatures.
The wearing part 40 includes a seating part 42 and a band part 41 and is configured to have a different curvature from the first curvature of the body (the curvature of the front surface of the body housing and the curved display) in the boundary area A between the seating part 42 and the band part 41. In addition, the curvature of a seating recess 33 on the side surface of the body is different from the first curvature in the boundary area A. When the curvature provided by the seating recess 33 and the seating part 42 in the boundary area A is smaller than the first curvature provided by the body 30, the wearable device makes a user who has a small wrist curvature feel good when the user wears it. When the curvature provided by the seating recess 33 and the seating part 42 in the boundary area A is greater than the first curvature provided by the body 30, the wearable device makes a user who has a large wrist curvature feel good when the user wears it.
