In addition, the wearable smart device 10 may have the form of a watch that is similarly worn on the wrist. However, the wearable smart device 10 of the present application may have various configurations, for example, in the form of a necklace or a ring. That is, the configuration and description for a particular type of wearable smart device 10 may be applied generally to other types of wearable smart devices 10 as well as to a particular type of wearable smart device 10. [
Following the general construction of the wearable smart device 10 described above, the overall structure of the wearable smart device 10 will be outlined with reference to the associated drawings. In this regard, FIG. 2 is a perspective view showing a wearable smart device according to an example of the present application, and FIG. 3 is a sectional view showing a wearable smart device obtained along the line A-A of FIG. 2 and 3 show all the overall structure of the wearable smart device 10, all the following descriptions of the present application will always refer to Figs. 2 and 3 basically do.
A wearable smart device (hereinafter "device") 10 may include a body 100. The body 100 can provide most of the functionality as a smart device to the user and thus is configured to include various components therein. In practice, the device 10, i.e., the body 100, may have a housing or case 110. The body 100, that is, the case 110, as shown, may form an internal space of a predetermined size to accommodate various components. The case 110 may also have an opening 110a communicating with the inner space so that the components can be installed in the inner space as shown in Fig. The case 110 may consist of an assembly of members coupled together, but may be made entirely of one piece so that the body 100, and further the device 10, may be compact.
Meanwhile, the wearable smart device 10 can be worn on various parts of the user's body. In particular, the wearable smart device 10 may be worn as a watch or bracelet on the wearer's wrist of the wearer's body. The body 100 may have a generally plate-like shape so that it can be worn on the user's wrist and at the same time provide various functions as a smart device. In addition, since the wearer's wrist includes a large curvature, the wearable smart device 10 can have a curvature that substantially matches the shape of the user's wrist, that is, the curvature thereof, in order to wind the wrist. Thus, the body 100 and the case 110, which are part of the wearable smart device 10, may also have a predetermined curvature according to the curvature of the user's wrist.
The wearable smart device 10 may also include a band 200 that is connected to the body 100. Since the body 100 consists of a case 110 that accommodates parts, the band 200 can be actually connected to the case 110. As described above, the band 200, like the body 100, has a curvature that substantially matches the shape of the user's wrist, i.e., its curvature, so that the device 10 can be worn on the wrist of a curved user , And has a plate shape as a whole. Thus, the body 100 and the band 200, i.e., the device 10, coupled to each other may have a closed loop or ring shape that wraps the user's wrist as a whole. This shape allows the device 10 to function basically as an accessory, such as a bracelet, as well as a smart device.
Since the body 100 accommodates various components, it needs to be configured to protect these components. Thus, the body 100, particularly the case 110, can be non-deformable, i.e. rigid, and thus made of a relatively rigid material such as metal or plastic. On the other hand, the band 200 can be configured to worn the device 10, more precisely the body 100, on the wrist. More specifically, the device 10 needs to be opened in order for the device 10 to be worn on the user's wrist or removed from the wrist. That is, a part of the closed ring-shaped device 10 needs to be discontinuous. Through the gap created by this discontinuity, the wrist of the user can be inserted into the device 10 and be wrapped by the device 10. The user's wrist can also be withdrawn from device 10 and separated from device 10 through the gap. However, as described above, since the body 100 is formed to be rigid, the band 200 may be separated from the body 100 to form the gap instead of the body 100, . Further, the gap formed by the separation of the band 200 or the cutting of the band 200 needs to be further expanded so that the wrist of the user can be inserted into the gap or can escape through the gap. Therefore, the device 10, that is, the band 200 needs to be deformably deformed so that the user can smoothly put on or take off the device 10 by the expansion of the gap. For this reason, the band 200 may be made of a material having a certain degree of flexibility or elasticity. For example, the band 200 may be formed of leather, rubber, silicone, synthetic resin, or the like.
If the band 200 itself is cut or split into two parts to form the gap, the parts of the band 200 must be reconnected in order to stably wear the device 10. Therefore, a ferrner (not shown) may be attached to the band 200 for such selective separation and connection. For example, the fesner can be implemented by buckle, a snap-fit hook structure, or velcro (trademark). However, such an attachment, such as a Fasner, protrudes out of the device 10, i.e. the band 200, so that the volume of the device 10 is increased and the device 10 can not have a good appearance. Thus, the band 200 itself can be separated directly from the body 100 to form a gap. That is, the band 200 itself may be detachably coupled to the body 100. Therefore, due to the removable band 200, the gap can be formed between the band 200 and the body 100 without being formed in the band 200. When the band 200 is detachable from the body 100, a structure for selectively separating and coupling the band 200 and the body 100 is installed in the body 100 without being exposed to the outside of the device 10 . That is, the device 10, such as the Feller, that is, the attachment exposed to the outside of the band 200 is not required. Accordingly, as shown in FIGS. 2 and 3, the band 200 can be formed smoothly as the body 100. For this reason, the device 100 can have a slim and uniform appearance due to the removable band 200 from the body 100. This enhanced appearance allows the device 100 to be a bracelet as a practical accessory as well as a smart device.
On the other hand, since the sizes of people's wrists are different from each other, the size of the device 10, precisely the circumferential length, needs to be adjusted to fit the size of the actual user's wrist so that the device 10 can be stably worn. If an attachment, such as a facer, is provided to the device 10, the circumferential length of the device 10, i.e., the band 200, can be adjusted to fit the wrist of the user. However, if the band 200 is detachably provided to the body 100 without such attachment for an improved appearance of the device 10, the size of the device 100 needs to be adjusted in a different manner. Thus, instead of directly adjusting the size of the band 200, i.e., the circumferential length, the band 100 can be replaced with another band having a different size. By simply replacing the band 100, the size of the device 10 can be easily adjusted to fit the wrist of the user. More specifically, the band 200 may be configured to be completely separate from the body 100 to enable band 200 replacement. As already described above, the band 200 can be removably coupled to the body 100 such that the device 10 can be worn or peeled off to the user. Considering the shape of the device 10 consisting of a totally closed ring, the band 200 can be connected at two points as shown with the body 100, at which point the band 200 is connected to the body < RTI ID = (100), a gap may be formed for wear and tear of the device (10) as described above. Thus, only the separation of the band 200 at any one of the connected points may be required for the wear and tear of the device 10. That is, the band 200 may be partly separated from the body 100 in part for the wear and tear of the device 10. On the other hand, as described above, the band 200 can be completely separated from the body 100 for size adjustment of the device 10, that is, replacement of the band 200. As a result, as shown in Figures 2 and 3, the device 10 according to one example of the present application can be used to partially separate the band 200 for wear and tear, Lt; / RTI > Thus, in accordance with the configuration of band 200 described above, device 10 can provide sufficient functionality for wear and tear, while improving the overall appearance. As such a separation structure of the band 200, the device 10 includes first and second connectors 300 and 400, which will be described later in detail with reference to the related drawings.
As described above, in terms of functionality, the body 100 can be configured to support a variety of electronic and mechanical components that are basically required for operation of the wearable smart device 10. Further, the body 100 may be configured to form a space for accommodating the components. 2 and 3 show well the components of the wearable smart device 10 as well as the overall structure thereof, the internal components of the device 10 will now be described in more detail below with reference to Figures 2 and 3 again.
The wearable smart device 10 may include a display unit 15a as an output unit 15. The display unit 15a may be exposed from the device 10 so that the wearable smart device 10 is visible to the user in a worn state. The display unit 15a may be disposed on the outer circumference of the body 100 having a predetermined curvature so as to be exposed to the user. Accordingly, the display unit 15a can be exposed to the outside from the body 100, and at the same time, the external shape of the body 100 can be formed. More specifically, the display unit 15a may be disposed to cover the body 100, that is, the opening 110a of the case 110. In addition, the display unit 15a may have a curvature corresponding to the curvature of the body 100 so as to form an outer shape of the body 100 having a curvature. 3, the case 110 may have a seat 110b formed of a flange extending inwardly of the opening 110a, and the display unit 15a may have a seat 110b on the seat portion 110b . Therefore, the case 110, i.e., the body 100, can stably support the display unit 15a. The display unit 15a is disposed on the outer periphery of the body 100 so that the display unit 15a is exposed to the user while the decorative member 120 is disposed on the inner periphery of the body 100 as opposed to the display unit 15a, As shown in FIG. The decorative member 120 may have a variety of colors and patterns, thereby improving the appearance of the device 10. [ The decorative member 120 also has a curvature corresponding to the curvature of the body 100 and can be inserted into the recess 100c formed in the body 100, that is, the inner peripheral surface of the case 100.
The display unit 15a can provide various information to the user. More specifically, the display unit 15a can display information to be processed in the wearable smart device 10. For example, the display unit 15a basically outputs various image and text information, and displays execution screen information of an application program driven by the wearable smart device 10, UI (User Interface), GUI (Graphic User Interface) can be displayed. Furthermore, the display unit 15a can inform the user of the current time. In order to display the current time, the display unit 15a can directly display the number corresponding to the current time, and can display a dial or a face and hands as an analog clock. That is, the display unit 15a and other electronic components related thereto can realize an electronic and virtual clock in the smart watch.
The display unit 15a may be a liquid crystal display (LCD), a thin film transistor-liquid crystal display (TFT LCD), an organic light-emitting diode (OLED) display, a 3D display, and an e-ink display. In addition, the display unit 15a may be provided in the wearable smart device 10 more than once, if necessary. For example, an additional display unit may be provided to be exposed to the user at a position opposite to the display unit 15a shown in the figure. 2, an additional display unit may be provided at the bottom of the band 200 facing the display unit 15a above the body 100. [
The display unit 15a may include a display module 15f and a window 15e covering the display module 15f. The display module 15f may be a display element such as an LCD or an OLED as described above, and is a component that actually displays image information. The window 15e may be disposed at a portion exposed to the user of the display module 15f and may protect the display module 15f from the outside. In addition to this protection function, the window 15e should allow the information displayed on the display module 15f to be seen by the user. Accordingly, the window 15e can be made of a material having appropriate strength and transparency. Accordingly, the window 15e can be made of a material having appropriate strength and transparency. That is, the window 15e can function as a glass or crustal member in a conventional clock. In addition, if the window 15e is made of a totally transparent material, other parts or internal parts of the wearable smart device 10 as well as the display module 15f can be exposed to the user, The appearance can be inhibited. Therefore, preferably, a part of the window 15e excluding the predetermined area for exposing the image information of the display module 15f may be opaque. More specifically, the outer circumferential portion surrounding the display module 15f on the rear surface of the window 15e may be coated or attached with an opaque layer. This opaque layer can be called a bezel. On the rear surface of the window 15e, the display module 15f can be directly attached as shown. The display module 15f can be directly attached to the window 15e in various ways, and the adhesive can be most conveniently used for direct attachment.
The display unit 15a may include a touch sensor that senses a touch with respect to the display unit 15a so that a control command can be received by a touch method. When a touch is made to the display unit 15a, the touch sensor senses the touch, and the control unit 18 generates a control command corresponding to the touch based on the touch. The content input by the touch method may be a letter or a number, an instruction in various modes, a menu item which can be designated, and the like. The touch sensor may be formed of a film having a touch pattern and disposed between the window 15e and the display module 15f or may be a metal wire directly patterned on the back surface of the window 15e. Alternatively, the touch sensor may be formed integrally with the display module 15f. For example, the touch sensor may be disposed on the substrate of the display module 15f, or may be provided inside the display module 15f. In this manner, the display unit 15a forms a touch screen together with the touch sensor And in this case the touch screen can function as a user input 12c (see FIG. 1). If desired, a physical key (e.g., a push key; see FIG. 2) adjacent to the display portion 15a, which is a touch screen, may additionally be provided for a user's convenient input with the user input portion 12c. In accordance with such a complicated configuration of the display module 15f, the display module 15f is represented by a module or an assembly of a plurality of layers, that is, components, in the accompanying drawings.
The substrate 13 is a component that is mounted with various electronic components, particularly various circuits and elements that assists various processors that make up the control unit 18, and can be installed in the body 100, have. Although not shown in detail, each of the components 11-19 shown in Fig. 1 may be installed directly on the substrate 13 so as to be controlled by the control unit 18, or installed in the case 110 And may be electrically connected to the substrate 13. For example, the control unit 18 can receive a command from the touch sensor of the window 15e or an operation by the operation of the input unit 12c. Based on the received command, the control unit 18 can display various parts including the display module 15f Can be controlled. Accordingly, the control unit 18 may be called various names such as a controller and a controlling device, and may control the SmartWatch 100 and all of its components. Such a controlled component includes not only the components included in FIG. 1 but also other components to be described below.
Since the wearable smart device 10 also functions as an accessory such as a bracelet, the device 10 needs to be compact in order to have a good appearance. However, a large number of parts are required for the device 10 to function as a smart device. If all of these parts are housed in the body 100, the body 100 may be of a large size, and such a large size may not be desirable for a good appearance as an accessory. Thus, in the device 10 according to an example of the present application, all of the components are not disposed in the body 100, and the band 200 can be configured to accommodate some components.
The wearable smart device 10 may include a battery 19a as a power supply 19 for supplying power. The battery 19a generally has a large volume and can be proportionally large in volume for a large capacity to provide sufficient operating time for the device 10. [ Therefore, in consideration of the limited space in the body 100 and the case 110, the battery 19a may be disposed in the band 200. [ First, the battery 19a may be detachably attached to the band 200. As shown in FIGS. 2 and 3, the band 200 may include a predetermined recess 210, and the battery 19a may be inserted into or withdrawn from the recess 210. More specifically, the battery 19a may be received in the housing 19c and the housing 19c may include a mechanism that can engage with or release the band 200, i.e., the inner wall of the recess 210 can do. That is, the battery 19a and the housing 19a can form a battery module that is detachable from the band 200 substantially. Thus, this modularized battery 19a allows for easy insertion or withdrawal, and can provide convenience to the user. On the other hand, although not shown, the battery 19a may be built-in to the band 200. [ More specifically, the battery 19a is disposed in the band 200 so as not to be exposed to the outside, and thus can be substantially integrated with the band 200. [ On the other hand, the battery 19a may be exposed to the outside of the band 200 even when it is integrally formed with the band 200. [
The battery 19a may be heavier than the band 10, especially the band 200, which does not include many components, as it has a sizable size, as described above. If the battery 19a is eccentric from the center of gravity of the band 200, the device 10 may be disproportionately worn on the wearer's wrist and the user may feel uncomfortable. Thus, the battery 19a may be disposed on the center of the band 200, that is, on the center of gravity. More specifically, the battery 19a may be disposed at a central portion in the longitudinal direction of the band 200, as shown in the figure. In addition, while the battery 19a is disposed in the band 200, various components requiring the power of the battery 19a are disposed in the body 200. [ Accordingly, as shown in FIG. 2, the band 200 may include a connection module 220 configured to supply power to the body 100 of the battery 19a. In order to supply power, one end of the connection module 220 may be connected to the battery 19a and the other end may be connected to the body 100. The connection module 220 may include an insulator covering the wire and the wire. That is, the connection module 220 may be configured to electrically connect the body 100 and the battery 19a to supply power. Also, the battery 19a can be charged by an external power source. If the battery 19a is attached to the device 10, that is, the band 200, a charging terminal may be provided to the body 100 or the band 200, and the terminal may be connected to an external power source Can be connected. Also, if the battery 19a is disconnected from the device 10, the battery 19a may be connected to be charged with external power by a separate charger. On the other hand, the battery 19a may be configured to be wirelessly chargeable through a wireless charger. The wireless charging may be implemented by a magnetic induction method or a resonance method (magnetic resonance method).
Referring again to FIG. 2, the wireless communication unit 11 may be included in the band 200 instead of the body 100 having a limited space. 1, the wireless communication unit 11 includes a broadcast receiving module 11a, a mobile communication module 11b, a wireless Internet module 11c, a short distance communication module 11d, and a location information module 11e. Lt; / RTI > For example, Bluetooth, NFC, WiFi, etc. can be integrated into one communication module. In addition, the antenna may be integrated into the wireless communication unit 11 as well. Thus, the wireless communication unit 11 can communicate with external devices and networks in all possible ways. In addition, the wireless communication unit 11, that is, the communication module may be formed integrally with the connection module 220. By such integration, the production cost of the device 10 can be reduced and the assembly productivity can be improved. In addition, since the integrated communication and connection module has a small volume, the size of the band 200 may not be substantially increased.
By arranging some of these parts, the battery 19a and the communication module 11 in the band 200, the parts of the device 10 can be dispersed in the body 100 and the band 200. Thus, the internal space of the device 10 can be utilized to the maximum. Because of this optimal placement, the overall size of the device 10 can be designed to be quite compact, and thus the appearance of the device 10 can be further improved. On the other hand, the parts described above mostly have a considerably large size. Thus, the wearable smart device 10, that is, the body 100 or the band 200, must have an outer shape suitable for the device 10 to be accommodated or installed therein. For this reason, the wireless communication unit 11, the substrate 13, the display unit 15a, the battery 19a, and the like can be manufactured to have a predetermined curvature. In particular, the display portion 15a, that is, the module 15e and the window 15f may be formed of a flexible display made of a material such as plastic, which is entirely deformable. Likewise, the wireless communication unit 11 and the connection module 220, that is, the integrated communication / connection module may be formed of a flexible printed circuit board (FPCB) for flexibility sufficient for deformation having a predetermined curvature. The substrate 13 may also be made of FPCB, but does not have sufficient strength to install the FPCB many electronic components and processors. Therefore, as shown in FIG. 2, the substrate 13 may be formed of a folded conventional PCB (Printed Circuit Board). The folded substrate 13 may be embedded in the interior of the curved body 100 and may have sufficient space and strength to mount many electronic components thereon.
The band 200 may be removably attached to the body 100 for wear and tear of the device 10 and for size adjustment of the device 10 (i.e., replacement of the band 200) Lt; / RTI > Since the device 10 has a closed ring shape as a bracelet, the body 100 and the band 200 can be joined to each other at two different points. That is, the body 100 has first and second ends 100a and 100b opposite to each other, and the band 200 may have first and second ends 200a and 200b facing each other. The first ends 100a and 200a of the body 100 and the band 200 may be connected to each other and the second ends 100b and 200b may be connected to each other. 2 and 3, the device 10 includes two mechanisms for connecting the body 100 and the band 200 to each other, that is, the first connection 300, And a second connection part 400. [ The first connection part 300 may be configured to couple the first end 200a of the band 200 to the body 100 or to separate the first end 200a of the band 200 from the body 100. [ The second connection unit 400 may be configured to couple the second end 200b of the band 200 to the body 100 or to separate the body 200 from the body 100. [ The first connection part 300 connects the first end 200a of the band 200 to the first end 200a of the body 100 and the second end 200a of the body 100, And the second connection part 400 may be configured to connect the second end 200b of the band 200 to the second end 200a of the body 100, And may be configured to be coupled to the end 100b or to be separated from the second end 100b.
The first and second connection portions 300 and 400 may selectively separate the first and second ends 200a and 200b of the band 200 from the body 100 to provide different functions. As already discussed above, the separation of the band 200 required for wear and tear of the device 10 and the separation of the band 200 required for the adjustment of the size of the device 10 may be different from each other. Selective separation at these connections is described in more detail below with reference to the associated drawings further in Figures 2 and 3. In this regard, FIG. 4 is a perspective view and a partially enlarged view showing a body and a band of the wearable smart device separated from each other at the first connection portion, and FIG. 9 is a perspective view and a partial enlarged view showing the body and band of the wearable smart device separated from each other at the first and second connection portions, And FIG.
As described above, when the band 200 is separated from the body 100 in any one of the first and second connection parts 300 and 400, the device 10 is connected to the body 100 and the band 200, A gap may be formed. The user's wrist can be inserted into the device 10 while being wrapped around the body 100 and the band 200 through the gap and the band 200 and the body 100 can be connected again after the insertion. On the other hand, the user's wrist can be pulled out of the device 10 through the gap. By such insertion and removal, the device 10 can be worn or peeled off to the user. As a result, wear and tear of the device 10 can be achieved by partial separation of the band 200, i.e., separation from the body 100 of the band 200 at either of the connection portions 300, 400 . 4, the first connection part 300 of the device 10 according to an exemplary embodiment of the present application may be connected to the band 300, 400. In addition, the partial separation may be performed in any one of the connection parts 300, 400, (200). More specifically, the first connection portion 300 is configured to separate the band 200, that is, the first end 200a thereof, from the body 100, to wear the device 10 to the user or to remove it from the user. Lt; / RTI > Since the wear and tear of the device 10 requires separation from the body 100 of the band 200 at only one of the connection portions 300 and 400, only the first connection portion 300 It can be separated from the body 100. That is, the band 200 can be separated from the body 100 only at the first connection portion 300 for wearing and peeling the device 10. On the other hand, as shown in FIG. 4, the second connection part 400 can maintain the coupling between the body 100 and the band 200. In addition, since the band 200 is made of a flexible material, the gap formed by the first connection portion 300 can be expanded while being deformed, as shown in FIG. The user's wrist can be easily inserted into or withdrawn from the extended gap, thereby allowing the user to easily wear or remove the device 10. [
On the other hand, as described above, the device 10 does not include a conventional length adjustment attachment, such as a fasner, installed in the band 200 to have an improved appearance, so to adjust the size of the device 10, 200 need to be replaced with bands having different sizes. Such replacement of the band 200 and adjustment of the size of the device 10 accordingly can be achieved by complete separation of the band 200 from the body 100. More specifically, as shown in FIG. 9, to replace the band 200 with another band and to adjust the size of the device 10, the first and second connectors 300, (100). ≪ / RTI > That is, the first and second connection portions 300 and 400 may be configured to separate both the first and second ends 200a and 200b of the band 200 from the body 100.
The first and second connection portions 300 and 400 may require a user's operation to separate the band 200 from the body 100. However, if the first and second connection portions 300 and 400 are adjacent to each other, it may be inconvenient for the user to operate these connection portions 300 and 400. [ Accordingly, the first and second connection portions 300 and 400 may be spaced apart from each other by a predetermined distance. More specifically, as best shown in FIG. 2, the first and second connectors 300, 400 are disposed adjacent to both sides of the user's wrist after the device 10 is worn on the wearer's wrist . With such an arrangement, the first and second connection portions 300 and 400 are spaced apart from each other by a sufficient distance, and can be directly accessed by the user. Accordingly, the user can easily separate the band 200 by operating the first and second connection portions 300 and 400 with ease.
Following the basic functions of the first and second connections 300 and 400, the structures of these connections 300 and 400 are described. The structure of the first connection portion 300 will be described first with reference to the related drawings. FIG. 5 is a partial cross-sectional view showing a band-separated body. FIG. FIG. 6 is a partial perspective view showing a body connected to an external power source in a state separated from a band, and FIG. 7 is a sectional view taken along line B-B of FIG. Also, for better understanding, Figures 2-4 are also referenced in the following description.
Since the device 10 includes various electronic components, it is necessary to be continuously powered to operate these electronic components. Thus, the device 10 may include a first terminal 16a configured to supply power to the body 100 as the interface portion 16. The first terminal 16a may be made of a conventional power supply terminal. However, these conventional terminals have a relatively large size relative to the compact device 10, i.e., the compact body 100 and the band 200. In particular, typical terminals are relatively thick and long. Thus, conventional terminals may be difficult to place in the body 100 or band 200, particularly their central portions, which are entirely curved and contain various components. Meanwhile, since the connection portions 300 and 400 are disposed at the end portions 100a, 100b, 200a, and 200b of the body and the band, they are spaced apart from the main components and have a relatively small curvature. Accordingly, the first terminal 16a may be disposed on one of the first and second connection portions 300 and 400, or may be disposed adjacent to the connection portions. That is, the first terminal 16a may be disposed at any one of the end portions 100a, 100b, 200a, and 200b of the body and the band, or may be disposed adjacent to any one of the end portions.
On the other hand, the device 10 is most likely to be worn on the wrist of a user, and thus may be exposed to water. For example, when washing hands or raining, the device 10 may be exposed to water. If the first terminal 16a is always exposed to the outside of the device 10, water may flow into the first terminal 16a and a failure of the device 10 may occur. Accordingly, the first terminal 16a may be disposed so as not to be exposed to any one of the connection portions 300 and 400 at all times. However, since the first terminal 16a must be exposed to the outside of the device 10 when connected to at least an external power source, the first terminal 16a may be selectively exposed. The user often wears or takes off the device 10 so that the band 200 can be frequently disconnected from the body 300 at the first connection 300 and the first connection 300, The first end portions 100a and 200a of the first electrode 200 may be exposed to the outside frequently. Thus, the first terminal 16a may be disposed on or adjacent to the first connection 300, i.e., the first ends 100a, 200a, for selective exposure. In addition, since the body 100 includes most of the electronic components, the first terminal 16a can be disposed on the body 100, i.e., the first end 100a, to easily supply power to the components. have. Consequently, as best shown in FIG. 5, the body 100 may have a first terminal 16a disposed at or adjacent to the first connection 300 or the first end 100a of the body. When the first connection part 300 separates the band 200 from the body 100, the first terminal 16a is exposed from the body 100 and can be connected to the external power source. The first terminal 16a may be concealed and protected from water while the first connector 300 joins the body 200 with the band 200, i.e., while the user wears the device 10. [ Therefore, the first terminal 16a is exposed to the outside in order to perform the intended function only when the band 200 is detached from the first connection part 300, so that when the user wears the device 10, Do not. Thus, such a first terminal 16a can improve the appearance of the device 10, while at the same time allowing the user to use the device 10 conveniently.
As described above, various conventional power supply terminals can be applied to the first terminal 16a. It is possible to exchange data between the device 10 and the external destination as well as to supply the USB terminal power among these conventional terminals. Accordingly, the first terminal 16a may be a USB terminal so as to provide an additional function. When the first terminal 16a is exposed by separation of the band 200 in the first connection part 300 as shown in Figs. 4, 6 and 7, And may be connected to an external power source to supply power to the main body 100. As shown in the figure, the first terminal 16a is formed of a female terminal, and the charging cable P may have a male terminal inserted into the first terminal 16a. On the other hand, the device 10 may be a smart device and may contain personal information of the user. For example, information such as contacts, text messages, etc. may be stored in the device 10. Further, in recent years, the smart device also performs electronic payment, so that the device 10 can also store the user's financial information. In order to protect such sensitive information, the device 10 needs to be provided with a security device. Thus, as best shown in Figures 5-7, the device 10 may include a recognition module 14c configured to recognize a user's fingerprint with a sensing portion 14 (see Figure 1). The recognition module 14c recognizes the fingerprint of the user, and the control unit 18 can compare the recognized fingerprint with the previously registered fingerprint. If the recognized fingerprint matches the registered fingerprint, the user can access the predetermined information stored in the device 10 or instruct the device 10 to perform a predetermined operation. On the other hand, if the recognized fingerprint does not match the registered fingerprint, the instruction to access and operate the information may be rejected. Thus, the recognition module 14c can provide sufficient security for the device 10. The recognition module 14c has a relatively large size as compared with the compact device 10 like the first terminal 14c. Therefore, for the same reason as the first terminal 14c described above, the recognition module 14c may be disposed in one of the first and second connection portions 300, 400 or adjacent to the connection portions. The recognition module 14c also has a similar feature, i.e. a large size, to the first terminal 14c so that if they are placed in different parts of the device 10, Should be individually designed to suitably accommodate the first terminals 14c. Therefore, it may be preferable to arrange the recognition module 14c and the first terminal 16a at least adjacent to each other, since it is possible to reduce the design consideration. In addition, the recognition module 14c may be arranged to be easily connected to the control unit 18 accommodated in the body 100 and processing the recognized fingerprint. Accordingly, the recognition module 14c may be disposed at or adjacent to the first connection portion 300, i.e., the first end 100a of the body 100, adjacent to the first terminal 16a. Furthermore, the recognition module 14c needs to be in direct contact with the user's finger for fingerprint recognition, and thus needs to be partially exposed to the outside of the device 10. The recognition module 14c can be stacked on the first terminal 16a at the first connection 300 and at the same time can be partly attached to the device 10, Lt; / RTI > By placing such relatively large volume of parts in either part of the device 10, i.e., the first end 100a, large parts can be optimally placed in the device 10. [ Thus, the overall size of the device 10 can be kept compact, and thus the appearance of the device 10 can be further improved.
The first end 100a of the body 100 is more detailed in order to make the device 10, that is, the body 100, compact while stacking the recognition module 14c and the first terminal 16a of a large size, . ≪ / RTI > 7, since the recognition module 14c is a sensitive component, a spacer 131 may be interposed between the first terminal 16a and the recognition module 14c for electrical insulation have. The first end 100a includes a substrate 132 for connecting power to the substrate 13 by the first terminal 16a and a bracket 133 for fixing the first terminal 16a to the first terminal 16a, May be included below (16a). In an assembly in which a plurality of such components are stacked, most components other than the recognition module 14c and the first terminal 16a are also indispensable. In addition, other components also have thicknesses that are minimally required. Accordingly, the first end 100a, furthermore, the body 100, The total thickness of the thick recognition module 14c and the first terminal 16a may be limited to a predetermined ratio with respect to the thickness T of the body 100, that is, the first end 100a. More specifically, in consideration of the minimum thicknesses of the other components to be laminated together, the sum of the thicknesses of the recognition module 14c and the first terminal 16a is the same as that of the body 100 shown in Fig. 7, 0.0 > 70% < / RTI > with respect to the total thickness of the substrate 100a. For example, when the thickness T of the body 100 is 6 mm, the thickness of the recognition module 14c is 1.2 mm, the thickness of the spacer 131 is 0.35 mm, the thickness of the first terminal 16a is 2.45 mm The thickness of the substrate 132 is 0.4 mm, the thickness of the bracket 133 is 0.7 mm, and the thickness of the decorative member 120 is 0.9 mm. Therefore, the total thickness of the recognition module 14c and the first terminal 16a is 3.65 mm, which can be set to less than 70% of the total thickness T of 6 mm, that is, about 61%. By limiting the ratio of the thickness sum of the recognition module 14c and the first terminal 16a, the device 10, i.e., the body 100, can be designed to be thin and compact, have.
Although the first terminal 16a is not exposed when the band 200 is coupled to the body 100 in the first connection 300 so that the first terminal 16a is protected from water and the band 200 is disconnected from the first connection 300, (Not shown). Therefore, the first terminal 16a and the peripheral portion thereof can be applied to an additional waterproofing mechanism so that the first connection portion 300 can be protected from water even when the band 200 is separated from the body 100. [ More specifically, the first terminal 16a can be covered with waterproof coding. Such a waterproof coating can be formed by attaching a film of a thin waterproof material to the surface of the first terminal 16a. For example, a conformal coating may be applied to the first terminal 16a as a waterproof coating. The first terminal 16a and the recognition module 14c may be connected to the substrate 13 inside the body 100 by an electrical connection member such as FPCB for example. More specifically, as shown in FIGS. 2 and 7, the connection member may be connected to the substrate 13 through an opening 110d formed in the case 110. FIG. However, the water introduced into the first terminal 16a while the first terminal 16a is exposed to the outside can reach the parts in the body 100 through the opening 110d. Accordingly, the body 100 may include a gasket 140 interposed between the connecting member and the outer periphery of the opening 110d. The gasket 140 can pass the connecting member but the remaining portions of the opening 110d can be sealed. The gasket 140 is made of a material that is somewhat deformable for complete sealing, and may be made of, for example, a liquid silicone rubber (LSR). The waterproof mechanism described above protects the first terminal 16a and its periphery from water, thereby preventing the device 10 from failing by water.
Referring to the related drawings, the structure of the second connection portion 400 will be described in detail below. FIG. 10 is a partial perspective view showing a second connection portion of the wearable smart device, FIG. 11 is a partial perspective view showing a structure of a latch and a periphery of the second connection portion, and a partial enlarged view showing a coupling and separation according to movement of the latch . FIG. 12 is a partial cross-sectional view showing a second connecting portion of the wearable smart device in detail, and FIG. 13 is a partial perspective view showing a second terminal of the body of the wearable smart device and its waterproof structure. Also, for better understanding, Figures 2, 3 and 9 are also referred to in the following description.
The band 200 includes a battery 19a and the battery 19a can supply power to the body 100 using the connection module 220. [ If the band 200 is disconnected from the body 100 from both the first and second connection portions 300 and 400 the battery 19a is also disconnected from the body 100 so that the supply of power is completely stopped . The device 10 is completely stopped while the power supply is stopped, so that it can not provide functions as a smart device. For example, the device 10 can not display time, and can not receive messages, calls, or the like. Further, since the device 10 must be rebooted when the band 200 is mounted, it may take a long time until normal operation becomes possible. Complete separation of the band 200 and thus interruption of the power supply may inconvenience the user. On the other hand, the user wears or takes off the device 10 frequently, while the user does not frequently replace the band 200. Although the complete disconnection of the band 100 and the interruption of the power supply are inevitable for the replacement of the band 200, the supply of the power continues so that the user is not inconvenienced during wear and tear of the frequently performed device 10 There is a need. That is, at least one of the connection portions 300 and 400 needs to maintain the coupling between the body 100 and the band 200 for supplying power from the battery 19a. As described above, wearing and peeling can only require removal of the band 200 at one connection. In practice, when the device 10 is worn or peeled off, the first connection part 300 separates the band while the second connection part 400 can maintain the engagement of the body 100 and the band 200. That is, the coupling of the body 100 and the band 200 in at least one connection, i.e., the second connection 400, when the device 10 is worn or peeled off, Should be maintained. Thus, the second connection portion 400 may be configured to supply power to the body 100 to maintain power even when the device 10 is worn or peeled off.
More specifically, as shown in FIGS. 10, 12 and 13, the device 10, as an interface unit 16, is electrically connected to the battery 19a to supply power to the body 100 And the second terminal 16b. The second terminal 16b may be disposed on or adjacent to the second connection 400 to maintain power supply during wear and undo. Since the second terminal 16b is configured to supply power to the components in the body 100, the second terminal 16b is disposed in the body 100, i.e., the second end 100b thereof, for easy connection with the components. Or disposed adjacent thereto. The second terminal 16b may be exposed from the second end 100b so as to be easily connected to the battery 19b of the band 200, i.e., the connection module 220, The second end 200b of the second housing 200 can be faced. The body 100 may thus include a second connection portion 400 or a second terminal 16b disposed at or adjacent to the second end 100b of the body 100. [ Referring to FIG. 12, the connection module 120 connected to the battery 19a extends to the second end 200b of the band 200. If the body 100 and the band 200 are coupled to each other in the second connection unit 400, the connection module 120 is connected to the second terminal 16b exposed to the outside of the first end 100b of the body 100 Can be combined. The second terminal 16b and the body 100 are electrically separated from the connection module 220 and the battery 19a when the second connection unit 400 separates the band 200 from the body 100, And the second terminal 16b may be exposed to the outside of the device 10. [ In addition, when the device 10 is worn or peeled off, the first terminal 16a is exposed to the outside (due to the separation of the band 200 in the first connection 300), while the second connection 400 is exposed The second terminal 16b may be connected to the battery 19a by the connection module 220. [ 6 and 7, when the charging cable P is connected to the first terminal 16a, the supplied power is supplied to the battery 19a via the first terminal 16a and the second terminal 16b . Thus, the battery 19a can be connected to the external power source by the first terminal 16a to be charged. That is, the first terminal 16a not only supplies power to the body 100 but also charges the battery 19a. In addition, since the battery 19a can be charged using the built-in first terminal 16a, an additional cradle may not be required to charge the battery 19a, and the battery 19a may be disconnected There is no need to be. Thus, the user can use the device 10 more conveniently.
When the second connection part 400 separates the band 200 from the body 100, the second terminal 16b can be exposed to the outside of the device 10 like the first terminal 16a. Therefore, the second terminal 16b and the peripheral portion thereof can be applied to a waterproof mechanism so as to be protected from water. More specifically, the second terminal 16b can be covered with a waterproof coding similarly to the first terminal 16a. For example, a conformal coating may be applied to the second terminal 16b as a waterproof coating. Further, the second terminal 16b can be connected to the substrate 13 inside the body 100 by an electrical connecting member such as FPCB, for example. 12, the connection member may be connected to the substrate 13 through an opening 110e formed in the case 110. In addition, as shown in FIG. However, the external water can reach the parts in the body 100 through the exposed second terminal 16b and the opening 110e. Accordingly, the body 100 may include a gasket 150 interposed between the connecting member and the outer peripheral portion of the opening 110d to seal the opening 110e. The gasket 140 may be made of a deformable material such as, for example, Liquid Silicone Rubber (LSR) for complete sealing. 12 and 13, the body 100 may include a waterproof ring 160 provided on the second terminal 16b. The ring 160 may be formed to surround the second terminal 16b. That is, the ring 160 can continuously extend along the outer periphery of the second terminal 16b. 12, when the band 200 is coupled to the body 100 in the second connection part 400, the ring 160 is interposed between the band 200 and the body 100, 200 and the body 100, respectively. Therefore, when the body 100 and the band 200 are coupled to each other in the second connection part 400, the ring 160 can seal the second terminal 16b so that water can not enter. The ring 160 can act as a kind of barrier even when the second connection part 400 separates the band 200 and exposes the second terminal 16b, It is possible to prevent the inflow of water to some extent. The above-described waterproof mechanism protects the second terminal 16a and the periphery thereof from water, thereby preventing the device 10 from being damaged by water.
The first and second connections 300 and 400 may perform different operations according to the functions intended for the device 10, particularly the band 200. For example, only the first connection part 300 can separate the band 200 from the body, and the first and second connection parts 300 and 400 are provided for the replacement of the band 200, Both can separate the band 200 from the body. Such operations may require a user's operation on the connection portions 300 and 400, so that the connection portions 300 and 400 may be further improved for the convenience of the user in consideration of the operation in the connection portions 300 and 400. [ Referring again to FIGS. 4, 9 and 10, the connection portions 300 and 400 will be described in detail again in terms of the operation of the user.
Firstly, wearing or removing the device 10 typically can be performed frequently during use of the device 10. Here, only the first connection portion 300 can separate the band 200 from the body 100 in order to wear and remove the device 10. Therefore, in order that the user can perform the intended function, that is, the wear and tear off and separation of the band 200 more conveniently through the operation of the connection portion, the band 200 is inserted into the body 100 from the first connection portion 300, The first direction which is a direction separating from the first direction can be set to a specific direction. That is, the first direction may be a direction in which the band 200 moves when the band 200 is separated from the body 100 in the first connection portion 300, and the setting of the first direction may be convenient for the user Can be determined. More specifically, the device 10 may have a closed ring shape for use as a bracelet, and the band 200 may be coupled to the body 100 at the first and second connectors 300, 400 . Also, when the device 10 is worn on the wrist of the user, the body 100 surrounds the upper part of the wrist, and the band 200 can cover the lower part of the wrist. As described above, in order for the device 10 to be peeled off, only the first connection portion 300 performs separation of the band 300, and the second connection portion 400 can maintain the coupling of the band 300. [ 4 and a partial enlarged view thereof, when the first connection part 300 separates the band 300, the body 100 is supported by the wrist while the band 200 is separated from the wrist It can fall in the direction of gravity, that is, downward due to its own weight. The band 300 or the second end 200b is constrained to the body 100 or the second connection part 400 by the engagement held in the second connection part 400, I.e., the first end 200a and the peripheral portions thereof may be separated from the body while moving in the circumferential direction of the body 100 or the device 10 itself. Also, considering the shape of the device 10, when the band 200 is separated from the first connection part 300, the first end 200a and the peripheral parts thereof are connected to the length of the body 100 or the device 10 itself Quot; direction. ≪ / RTI > Therefore, when the user separates the band 200 from the body 100 at the first connection portion 300 by the movement or separation in the longitudinal direction or the circumferential direction, Sufficient gaps can be created immediately to pull out the wrist. For this reason, the user does not need to further deform the band 200 to form the gap, so that the device 10 can be removed more conveniently. Also, when separating the band 200 from the first connection part 300 to form the gap in order to wear the device 10, the band 200 can show the same behavior as described above. In view of these advantages, the band 200 can be separated from the body 100 in the circumferential or longitudinal direction of the body 100 or the device 10. That is, the first connection part 300 may be configured to separate the band 200 from the body 100 in the circumferential direction or longitudinal direction of the body 100 or the device 10. As a result, the first direction in the device 10 according to one example of the present application can be the longitudinal direction of the body 100 or the wearable smart device 10 or its circumferential direction. Similarly, the band 200 can be coupled to the body 100 in the circumferential or longitudinal direction of the body 100 or the device 10. That is, the first connection unit 300 may be configured to couple the band 200 to the body 100 in the circumferential direction or longitudinal direction of the body 100 or the device 10.
On the other hand, both of the first and second connection portions 300 may separate the band 200 from the body 100 in order to exchange the band 200. However, unlike wear and tear of the device 10, replacement of the band 200 may not be performed frequently. Therefore, in the second direction in which the band 200 is separated from the body 100 in the second connection part 400, wear and tear of the device 10 may be considered as in the first direction. Since the first direction of the first connection unit 300 has been previously set, the first direction may be set to a specific direction in consideration of the first direction. That is, the second direction may be a direction in which the band 200 moves in the second connection part 400 when the band 200 is separated from the body 100, and may be set in conjunction with the first direction. More specifically, when the first connection 100 separates the band 200 to remove the device 10 from the wrist, the second connection 400 is also connected to the band 200 Can be released. Actually, the first and second connection portions 300 and 400 include a coupling mechanism for coupling the band 200 and the body 200 together. By manipulation of the user's coupling mechanism, the band 200 can be first removed from the body 200 and removed from the body 200 to be separated. If the band 200 is also separated in the circumferential direction in the second connection part 400 as well, the entire band 200 is separated from the body 100 by the number of operations, 2 connecting portions 300 and 400, respectively. However, as is well shown in FIG. 9 and a partially enlarged view thereof, if the band 200 is separated in the second connection portion 400 in the radial direction, i.e., in the direction perpendicular to the circumferential direction, Even if the coupling mechanism releases the band 200 from the body 100, the load of the band 200 acts in the downward direction, i.e., in the tangential direction in the circumferential direction. Thus, the band 200 is not detached from the body 100, and the device 10 can be removed using the separation of the band 200 conveniently only at the first connection 100 as intended. Also, when separating the band 200 from the first connection part 300 to form the gap in order to wear the device 10, the band 200 can show the same behavior as described above. Thus, the radial separation of the band 200 not only assures the convenience of the user, but also the reliability of the device 10 can be improved. In addition, complete separation of the band 200 for replacement of the band 200 by radial separation of the band 200 can also be conveniently performed. In view of these advantages, the band 200 can be separated from the body 100 in a radial pattern of the body 100 or the device 10. More specifically, the band 200 may be separated radially inward as shown in Figures 9 and 10, but radially outward in the opposite direction. That is, the second connection part 300 may be configured to separate the band 200 from the body 100 in the radial direction of the body 100 or the device 10. As a result, the second direction in the device 10 according to one example of the present application can be the radial direction of the body 100 or the wearable smart device 10. [ The band 200 may be coupled to the body 100 either radially inwardly or outwardly of the body 100 or the device 10 at the second connection 400 opposite the second direction. That is, the second connection part 400 may be configured to couple the band 200 to the body 100 in the radial direction or outward direction of the body 100 or the device 10, opposite to the second direction.
The first and second connections 300 and 400 may include first and second coupling mechanisms, respectively, configured for separation and coupling of the band 200 as described above. First, with respect to the first connection 300, the first coupling mechanism is designed to perform the separation in the first direction of the band 200 and will be described in more detail below with reference to the related drawings. 8 is a perspective view showing the first connection portion of the wearable smart device in detail; In addition to Fig. 8, Figs. 4-7 relating to the first connection 300 can also be referred to for the description of the first mechanism.
As shown in FIG. 8, the first connection part 300 may include a first latch 310 provided in the band 200. The first connection portion 300 may include a locking member 320 provided on the body 100 and configured to be engaged with the first latch 310. The first latch 310 may be installed at the first end 200a of the band 200 and may be inserted or withdrawn along the longitudinal or circumferential direction of the body 100. [ The first latch 310 may extend in a circumferential direction for insertion into the body 100 and may be oriented toward the body 100. The first latch 310 may be a bar-shaped member as shown in FIGS. 4 and 6, and may include a recess 311 to be engaged with the lock member 320. A single first latch 310 may also couple and separate the bands 200 in the intended first connection 300, but for a more stable operation a pair of first latches 310 may be coupled to the first connection 310, (Not shown). The pair of first latches 310 may be spaced apart from the first end 200a of the band 200 by a predetermined distance.
The locking member 320 may include a body 323 and a head 321 and may include a stopper 322 disposed between the body 323 and the head 321. The locking member 320 may be formed on the rear surface of the body 323 as indicated by a dotted line and may have a protrusion 324 selectively inserted into the first latch 310. The protrusion 324 may be inserted into the recess 311 of the first latch 310 such that the first latch 310 and the locking member 320 are engaged with each other. The locking member 320 may be oriented in the width direction of the device 10, i.e., the body 100, as shown. With this orientation, the locking member 320 can be oriented in a direction perpendicular to the first latch 310 to actually engage the first latch 310. More specifically, the locking member 320 may include an elastic member 325 disposed along the width direction of the device 10 or the body 100. Since the elastic member 325 can be restored after the deformation, the locking member 320 can be returned to the original position after moving in the width direction using the elastic member 325. [
The first connection part 300 may include a housing 330 to guide the restricting movement of the locking member 320 in the width direction. The housing 330 may have a container structure for receiving the locking member 320 and may form a first end 100a of the body 100 substantially. The housing 330 has a first side wall 331 adjacent to the side of the body 100 and the first side wall 331 can include an opening 331a. The head 321 may protrude from the housing 330 through the first side wall 331 of the housing 330 and further out of the body 100 while being supported by the elastic member 320. The stopper 322 may also be formed larger than the opening 331a of the first sidewall 100 and thus engage the first sidewall 100 to limit the movement of the locking member 320. [ The housing 330 may also include a second sidewall 332 that is opposite the first sidewall 331 and an elastic member 325 may be supported by the second sidewall 332. The housing 330 may have a guide wall 333 extending in the width direction of the body 100 and the lock member 320 may be guided to move in the width direction by the guide wall 331. [ The locking member 320 can be engaged with the first latch 310 or released from the first latch 310 while being moveable in the width direction of the body 100 in a recoverable manner. Also, the housing 330 may include an opening 331a into which the first latch 310 is inserted, as shown in FIG. If a pair of first latches 310 are provided, as shown, a pair of locking members 320 and a housing 330 may likewise be provided.
Fig. 8 shows the body 100 and the band 200 coupled to each other by virtue of the first coupling mechanism. If the head 321 is pressed as indicated by the arrow, the body 323 and the projection 324 are moved in the width direction and taken out from the recess 311. The first latch 310 is released from the locking member 320 and the first latch 310 is withdrawn from the housing 330 in the circumferential direction so that the band 200 is separated from the body 100 in the circumferential direction . On the other hand, when the removed first latch 310 is inserted again into the housing 330, the first latch 310 is engaged with the locking member 320 by insertion into the dolly 324 and the recess 311. Thus, the band 200 can be coupled to the body 100. The first latch 310 is described as being mounted on the body 200 and the first latch 310 is mounted on the body 200 while the locking member 320 is mounted on the body 100. However, 320 may be installed in the band 200. The first connection part may be provided on one of the band 200 and the body 100 and may be inserted into the other one of the band 200 and the body 100 along the longitudinal direction or the circumferential direction of the device 10. [ One latch 310 and the locking member 320 provided on the other of the band 200 and the body 100 and configured to engage the first latch 310. [
On the other hand, in connection with the second connection 400, the second coupling mechanism can be designed to perform the separation in the second direction of the band 200. This second coupling mechanism is described in more detail with reference to the associated drawings. FIG. 11 is a partial perspective view showing the structure of the latch of the second connection part and its surroundings, and a partially enlarged view showing the engagement and disengagement according to the movement of the latch. FIG. 11 shows a second coupling mechanism in which some parts, that is, the second body 423 of the housing 420 described later, are removed in order to better show the internal structure of the second coupling mechanism. 9, 10 and 12, which are additionally related to the second connection part 400 in FIG. 11, can also be referred to for the description of the second mechanism.
As shown in FIGS. 11 and 12, the second connection part 400 may include a second latch 410 provided in the band 200. The second connection portion 400 may include a flange 430 provided on the body 100 and adapted to engage with the second latch 310. The second latch 310 may be installed at the second end 100b of the band 200 and may be inserted into or detached from the body 100 along the radial direction thereof. The flange 430 may be formed as a part of the case 110 that is integrally formed with the body 100 and does not actually move. The flange 430 extends along the longitudinal or circumferential direction of the body 100 and also extends in the width direction. The flange 430 also has a plurality of notches 431 spaced apart from one another and a second latch 420 can be inserted into or withdrawn from the notch 431.
The second latch 410 may include a body 411 and a protrusion 412 provided on the body 411. The body 411 may be composed of a device in the form of a bar that extends in the width direction of the device 10, that is, the band 200. The body 411 may also include a head 411a that is exposed to the outside of the device 10, i.e., the band 200, so that the second latch 410 can be operated by a user. The head 411a may be exposed from the inner periphery of the device 10, i. E. The band 200, but may be exposed from its outer periphery, as shown. The protrusion 412 may extend in the longitudinal or circumferential direction of the device 10, that is, the band 200. The protrusion 412 may include an inclined surface 412a so as to be smoothly inserted into the notch 431 of the flange 430, as shown in Fig. The second latch 410 may include an elastic member 413 disposed along the width direction of the device 10 or the band 200. The body 411 may include a member 411b for engaging the elastic member 412 and the second latch 410. [ Since the elastic member 413 can be restored after the deformation, the second latch 410 can be returned to the original position after moving in the width direction by using the elastic member 413.
The second connection portion 400 may include a housing 420 to guide the restoring movement of the second latch 410 in the width direction. The housing 420 may have a container structure for receiving the second latch 410 and may form a second end 200a of the band 200 substantially. 10 and 12, the housing 420 may include a first body 421 and a second body 423 configured to entirely enclose the second latch 410 . The first body 421 may be disposed to face the body 100 and the second body 423 may be disposed to form an inner periphery of the band 200. [ The first body 421 may include both side walls and one of these side walls may support the elastic member 413 such that it can be deformed for movement and restoration in the width direction of the second latch 410 . In addition, the first body 421 may include an opening 422. The protrusion 412 of the second latch 410 protrudes out of the housing 420 through the opening 422 and the protruded protrusion 412 can engage with the body 100 or the flange 430 . The opening 422 may be formed larger than the projection 412 in the width direction to allow the second latch 410, i.e., the projection 412, to move in the width direction of the device 10. Also, the second body 423 may include an opening 423a. The head 411a may be exposed to the outside of the housing 420 through the opening 423a and may be operated by a user for operation of the second latch 410. [ The opening 423a of the second body may be formed wider than the head 411a so that the head 411a may be allowed to move in the width direction as in the case of the opening 422 of the first body. The second latch 410 can be guided to move in the width direction by the first and second bodies 421 and 413. Accordingly, the second latch 410 can be engaged with or released from the flange 430 while moving or returning in the width direction.
In addition, the housing 420 may be configured to guide the band 200 to join or separate from the body 100 while moving radially to the body 100. 10, the second connection part 400 may include a rib 424 provided on an outer surface of the housing 420. [ The second connection portion 400 may also include a groove 425 that is provided in the body 100 and is configured to receive the ribs 424. The ribs 424 may be formed on the side of the housing 420, i.e., the first body 421. Grooves 425 may also be formed on the side of body 100 to accommodate such ribs 424. The ribs 424 may also be oriented while extending in the radial direction of the device 10, i.e., the band 200, and the grooves 425 may be oriented in the radial direction of the device 10, i.e., . Thus, when the band 200 is radially engaged or disengaged from the body 100, the ribs 424 are inserted or withdrawn into the grooves 425, and thus the radial direction of the band 200 for engagement or disengagement As shown in FIG. A combination of a single rib 424 and a groove 425 may also provide the intended function as described above but a pair of ribs 424 and groove 425 may be provided in the housing 420 And both side portions of the body 100, respectively.
11 and 12 show the body 100 and the band 200 coupled to each other by virtue of the second coupling mechanism. The body 411 and the protrusion 412 can be moved in the width direction of the device 10 while deforming the elastic member 413 when the head 411a is pushed in the width direction as indicated by an arrow. By this movement, the protrusion 412 can be aligned with the notch 431 of the flange 430, as shown in the partial enlarged view in FIG. The bands 200 can then be moved radially in the device 10, precisely radially inward in the drawing, while being guided by the ribs 424 and the grooves 425, 431, respectively. Thus, the second latch 410 can be released from the flange 430. The band 200 can then be radially separated from the body 100 by subsequently stripping the band 200 into the radius of the device 10.
On the other hand, when the withdrawn band 200 is inserted into the body 100, it is guided by the ribs 424 and grooves 425 to move radially outwardly of the device 10, . Also, the projection 412, precisely its sloped surface 412a, can contact the side wall of the notch 431. The protrusion 412 can be gradually inserted into the interior of the notch 431 while the inclined plane 412a is guided by the side wall 431a while the band 200 is further moved by the user's push. The second latch 410, i.e., the body 411 and the protrusion 412 can be moved in the radial direction while compressing the elastic member 413 by the gradient of the inclined surface 412a. On the other hand, unlike the forced insertion of such protrusion 412, the protrusion 412 may be aligned with the notch 431 by pushing the head 411a in the width direction and then inserted into the notch 412 . When the projection 412 is completely inserted into the notch 431, the second latch 410, particularly, the projection 412 can be returned to the original position by the restoring force of the elastic member 413. [ Thus, the protrusion 412 is caught by the flange 430, and the band 200 can be coupled to the body 100. In the above description of the second coupling mechanism, the second latch 410 is described as being installed in the band 200, but it may be installed to have the same structure in the body 100 as well. The second connection portion 400 is provided on either the band 200 or the body 100 and is connected to the other of the band 200 and the body 100 by a second connection portion 400 inserted in the radial direction of the device 10. [ Latch 410 as shown in FIG. The second latch 410 may also be configured to engage the other of the band 200 and the body 100 while moving in the width direction of the device 10.
Both the first and second coupling mechanisms described above may require direct manipulation of the user. However, by including a suitably designed driving mechanism, the first and second coupling mechanisms can automatically couple or separate the band 200 to or from the body 100.
Other components of the device 10, in addition to the main components such as the first and second connections 300 and 400 described above, may be further improved to provide better functionality to the user. These improved components are described in detail below with reference to the associated drawings.
Only the first connection part 300 separates the band 200 from the body 100 while the device 10 is worn or peeled off so that the band 200 is connected to the body 100 through the second connection part 400 The battery 19a of the band 200 can supply power to the body 100 as well. However, since the band 200 is separated from both the first and second connection portions 300 and 400 while the band 200 is being replaced, the supply of power to the body 100 may be interrupted. As described above, interruption of the power supply disrupts the functioning of the smart device, and requires a reboot of the device 10, which can make the user uncomfortable. Thus, as shown in FIG. 14, the body 100 may include an auxiliary battery 19b configured to supply power to other components, including the display portion 15a. 14 is a cross-sectional view showing an example of a wearable smart device including an auxiliary battery.
More specifically, referring to FIG. 14, the auxiliary battery 19b has a predetermined curvature so that it can be installed in the curved body 100. Since the display portion 15a and the substrate 13 are disposed adjacent to the outer peripheral portion of the body 100, the auxiliary battery 19b is disposed adjacent to the inner peripheral portion of the body 100 to avoid interference with the auxiliary battery 19b . 3, a part of the inner periphery of the case 110 may be removed and an auxiliary battery 19b may be installed instead of the removed part. Therefore, even if the auxiliary battery 19b is additionally included, the thickness of the body 100 may not be increased. On the other hand, the auxiliary battery 19b may be added to the inside of the body 100 without removing the inner peripheral portion of the case 110. [ With this auxiliary battery 19b, even when the band 200 is replaced, that is, when the supply of power by the battery 19a is interrupted, the supply of power to the body 100 can be continued, ) Can be used more conveniently.
Further, since the device 10 has the wireless communication unit 11, it can function as an independent mobile terminal. The mobile terminal must have a unique ID to distinguish it from other terminals in order to prevent confusion of the line, and a SIM (Subscriber Identuty Module) card may be required for this purpose. Thus, as shown in FIG. 15, the device 10, i.e., the body 100, may include a tray 180 for receiving a SIM card. The tray 180 may be slidably mounted on the body 100. The tray 180 can be pulled out of the body 100 and then inserted into the body 100 to install the mounted SIM on the body 100. [ Such a tray 180 allows the user to more conveniently utilize the device 10.
Meanwhile, the display unit 15a is configured to provide visual information to the user. Further, since the display portion 15a has a considerably large size and is disposed on the outer surface of the device 10, it can greatly affect the appearance of the device 10 as an accessory. The display unit 15a needs to be designed in consideration of such functions as smart devices and accessories. Fig. 16 is a side view showing the formation range of the display portion of the wearable smart device, and Fig. 17 is a schematic view showing curvatures of the display portion of the wearable smart device. Referring to these figures, a display unit 15a optimized for the intended functions will be described in detail below.
The display unit 15a may be formed as large as possible so as to display a large amount of information on one screen. However, when the device 10 is worn on the wrist, the viewing angle of the user is limited, so that a part of the large display portion 15a may not be visible to the user. Therefore, the size of the display portion 15a needs to be designed in consideration of the environment in which the user uses the device 10. In practice, the user can, in many cases, use the device 10 during various tasks in the chair and table. That is, the user can see the display unit 15a of the device 10 worn on the wrist while sitting on the chair and placing the forearm on the desk. To determine the size, or range, of the display portion 15a in this environment, Figure 16 shows the device 10 worn on the wrist of the user's fist. Further, since the device 10 has a shape of a ring that is substantially closed, the range of the display portion 15a can be set based on the center O of the ring shape. More specifically, when a user's wrist is placed on a desk, portions adjacent to both sides of the wrist, i.e., portions adjacent to the central angles 0 DEG and 180 DEG, may not be well visible to the user. Instead, the points P1 and P2 at the central angles of 30 ° and 150 °, respectively corresponding to the central angle of 30 ° from the respective sides of the wrist, ie, the central angles 0 ° and 180 °, are included in the viewing angle . That is, the region between the central angle of 30 ° and 150 ° can be seen by the user. Accordingly, the display unit 15a includes a display unit 15a that displays the side portion and a central angle of 150 degrees from any one point P1 of the body that forms a central angle of 30 degrees with either side of the wrist when the device 10 is worn by the user. To another point P2.
Also, the curvature of the user's wrist is not substantially constant. That is, both sides of the user's wrist have a large curvature, while the top of the user's wrist may have a generally small curvature or may be flat. Accordingly, the display portion 15a can be designed in consideration of the curvature of the user's wrist. More specifically, the display portion 15a includes side portions S2 adjacent to both side portions of the wrist and a central portion S1 disposed between the side portions S2 when the device 10 is worn by the user . The curvature and curvature radius R2 of the side portions S2 and the curvature and curvature radius R1 of the center portion S1 may be set different from each other depending on different curvatures of the corresponding portions of the user's wrist described above. Also, the upper portion of the user's wrist is relatively large and flat compared to the side portions. In general, a flat display portion can provide better screen quality than a curved display portion. Accordingly, if the central portion S1 corresponding to the upper portion of the wrist is formed to have a flat or small curvature, the display portion 15a can secure a wide area that provides an improved appearance according to the curvature of the wrist, . For this reason, the curvature of the central portion S1 may be formed to be at least larger than the curvature of the side portions S2, and the central portion S1 may be formed further flat. Since the curvature and the radius of curvature are in inverse proportion to each other, the curvature radius R1 of the central portion S1 can be set to be larger than the curvature radius R2 of the side portions S2.
As described above, the band 200 can be completely separated by being separated from the body 100 at both of the first and second connection portions 300 and 400, and the other bands 200-1 and 200 -2). ≪ / RTI > The other bands 200-1 and 200-2 and the band 200 may have different sizes and the size of the device 10 may be adjusted due to the replacement of the band 200. [ More specifically, the band 200 may be replaced with other bands 200-1 and 200-2 having different sizes and interchangeable with each other to fit the size of the wrist of the user. That is, the body 100 may be combined with interchangeable bands 200, 200-1, 200-2 having different sizes to fit the size of the wrist of the user. As a result, the device 10 may include a plurality of bands 200, 200-1, 200-2 of different sizes and interchangeable to fit the size of the wrist of the user.
In addition, since the size of the user's wrist actually corresponds to the length of the inner periphery of the device 10, i.e., the inner periphery length, the adjustment of the size of the device 10 can be practically achieved by adjusting the inner periphery length. More specifically, the body 100 has a fixed inner circumferential length B, and the bands 200, 200-1, 200-2 may have different circumferential lengths C1, C2, C3. That is, the body 100 may be combined with any one of the bands 200, 200-1, 200-2 having different circumferential lengths C1, C2, C3. For example, the inner circumferential length B of the body is 80 mm, and the circumferential lengths C1, C2 and C3 of the bands 200, 200-1 and 200-2 are 84 mm, 74 mm and 64 mm, respectively. Such an interchangeable band 200 may allow the device 10 to have an exact size that fits the wrist of a user differently than a conventional band with a felt. Also, since there is no attachment such as a felt, the band 200 can have a smooth inner surface. Therefore, the device 10 can provide a user with a good fit and convenience in wearing.
Although the above examples illustrate the replacement of the band 200 to adjust the size of the device 10, the band 200 may be replaced with another band to change its color, design, . Therefore, the appearance of the device 10 can be improved by the replaceable band 200. Further, auxiliary devices that expand the functionality of the device 10 due to the interchangeable band 200 can be easily added, thereby having more extended functionality.
The foregoing detailed description should not be construed in all aspects as limiting and should be considered illustrative. The scope of the present invention should be determined by rational interpretation of the appended claims, and all changes within the scope of equivalents of the present invention are included in the scope of the present invention.
