FIG. 2 is a perspective view showing an embodiment of a wearable terminal 100 according to the present invention, and FIG. 3 is a view showing a state in which a body 101 of the wearable terminal 100 shown in FIG. It is a perspective view. 2 and 3, the wearable terminal 100 includes a main body 101 having a display unit 151, a frame 105 surrounding the main body 101, and a frame 105 extending from the frame 105, And a band 102 configured to be wearable.

The main body 101 includes a case which forms an appearance. As shown in the figure, the case includes a first case for providing an internal space for accommodating various electronic components such as a main board 185, a camera 121, and an audio output unit 152, And a second case. However, the present invention is not limited to this, and one case may be configured to provide the internal space so that the wearable terminal 100 of the uni-body 101 may be implemented.

These cases 101, 102, and 103 may be formed by injection molding of synthetic resin or may be formed of metal such as stainless steel (STS), aluminum (Al), titanium (Ti), or the like.

Meanwhile, the wearable terminal 100 may include a waterproof portion (see FIGS. 6 and 184) for preventing water from penetrating into the terminal body 101. For example, the waterproof portion is provided between the window 151a and the front case 101, between the front case 101 and the rear case 102, or between the rear case 102 and the rear cover 103, (See 183 in Fig. 6), so that the inner space of the main body 101 can be sealed at the time of engagement.

The wearable terminal 100 is configured to be capable of wireless communication, and the main body 101 may be provided with an antenna for the wireless communication. On the other hand, the antenna can expand its performance by using a case. For example, a case comprising a conductive material may be configured to electrically connect with the antenna to extend the ground or radiating area.

A display unit 151 may be disposed on the front surface of the main body 101 to output information, and a touch sensor may be provided on the display unit 151 to realize a touch screen. The window of the display unit 151 may be mounted on the first case 101a to form the front surface of the terminal body 101 together with the first case 101a.

The main body 101 may include an audio output unit 152, a camera 121, a microphone 122, a user input unit 123, and the like.

The display unit 151 displays (outputs) information processed in the wearable terminal 100. For example, the display unit 151 may display execution screen information of an application program driven by the wearable terminal 100, or UI (User Interface) and GUI (Graphic User Interface) information according to the execution screen information .

The display unit 151 may be a liquid crystal display (LCD), a thin film transistor-liquid crystal display (TFT LCD), an organic light-emitting diode (OLED), a flexible display display, a 3D display, and an e-ink display.

In addition, the display unit 151 may exist in two or more depending on the implementation of the wearable terminal 100. In this case, the plurality of display units may be spaced apart from each other on the one surface or may be disposed integrally with the wearable terminal 100, or may be disposed on different surfaces.

The display unit 151 may include a touch sensor that senses a touch with respect to the display unit 151 so that a control command can be received by a touch method. When a touch is made to the display unit 151, the touch sensor senses the touch, and the control unit 180 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 a film having a touch pattern and disposed between the window 151a and a display (not shown) on the rear surface of the window 151a, or may be a metal wire .

The sound output unit 152 may be implemented in the form of a loudspeaker for outputting various alarm sounds or multimedia reproduced sounds. Since the wearable terminal 100 is worn on the wrist, the acoustic hole 1055 through which the reproduced sound of the acoustic output unit 152 is outputted can not be positioned on the back surface, but is positioned on the side surface. However, since the frame 105 surrounding the periphery of the main body 101 covers the acoustic hole 1055, it is also possible to form an opening in the frame 105 at a position corresponding to the acoustic hole 1055.

The microphone 122 is configured to receive the user's voice, other sounds, and the like. The microphone 122 may be provided at a plurality of locations to receive stereophonic sound.

The terminal body 101 is provided with a power supply unit 190 (see FIG. 1) for supplying power to the wearable terminal 100. The power supply unit 190 may include a battery 191 built in the terminal body 101 or detachable from the outside of the terminal body 101.

The battery 191 may be configured to receive power through a power cable connected to the interface unit 160. In addition, the battery 191 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).

The frame 105 covers the periphery of the main body 101 in a ring shape in which the main body 101 is seated in the center. The frame 105 can be made of a rigid material and a flexible material so that the main body 101 can be easily attached and detached while maintaining its shape.

The frame 105 covers the peripheral portion of the main body 101 and the backward direction partially extends to support only the peripheral portion of the main body 101. [ This is because if the back surface of the main body 101 is entirely covered, the entire thickness of the wearable terminal 100 becomes thick. A frame 105 is formed so as to extend only up to the inclined surface portion of the main body 101 and the frame 105 and the back surface of the main body 101 are continuous when the main body 101 is engaged with the frame 105 Plane can be formed.

The band 102 is worn on the wrist so as to surround the wrist and can be formed of a flexible material for easy wearing. The band 102 of the present invention extends in the frame 105 and is integrally formed in the frame 105. [ That is, the flexible portion of the frame 105 and the band 102 can be injection-molded using a material having elasticity at the same time. For example, the frame 105 and the band 102 can be injection-molded using a TPU resin (Thermoplastic Polyurethane Resin).

The band 102 may be provided with a fastener 102a. The fastener 102a may be embodied by a buckle, a snap-fit hook structure, or a velcro (trademark), and may include a stretchable section or material . In this drawing, an example in which the fastener 102a is embodied as a buckle is shown. When the buckle fastener 102a is provided, the opposite band 102 may be provided with a hole 102b for inserting the fixing pin of the buckle.

4 is a view showing a connection pin 183 part of the wearable terminal 100 according to the present invention and FIG. 5 is a view showing a connection clip 188 part of the wearable terminal 100 according to the present invention, 6 is a sectional view showing a wearable terminal 100 related to the present invention.

Electronic components may be mounted on the band 102, and it is preferable that the band electronic component uses a member made of a flexible material without increasing the size of the band 102. For example, a flexible substrate 186 or a flexible battery may be provided.

The function of the flexible substrate 186 may be changed according to the conductive pattern formed on the flexible substrate 186. [ An antenna pattern can be formed in accordance with a communication frequency and used as an antenna, and a large conductive pattern can be formed to serve as a ground for an antenna mounted on the main body 101. Hereinafter, an embodiment in which an antenna is mounted on the main body 101 and a ground is formed on the flexible substrate 186 will be described as an example, but the electronic parts mounted on the band 102 are not limited thereto.

A connection clip 188 and a connection pin 183 may be provided for electrically connecting the band electronic component mounted on the band 102 and the main board 185 mounted on the main body 101. The connection clip 188 extends from the band electronic component and protrudes to the inner surface of the frame 105. The connection pin 183 protrudes from the side of the main body 101 and the inside is connected to the main board 185. [

One end of the connection pin 183 is exposed to one side of the main body 101 and extended to the inside of the main body 101 and connected to the main board 185 at the other end. And transmits the signal to the main board 185 when receiving the signal through the connection pin 183.

A ring-shaped waterproof portion 184 is formed between the hole and the connection pin 183 to form a hole in the body 101 and to insert the connection pin 183 into the hole and prevent water from flowing through the hole. As shown in FIG.

The connection clip 188 connected to the electronic component mounted on the band 102 is located on the inner surface of the frame 105 as shown in Fig. The frame 105 of the present invention protrudes in the lateral direction because it is difficult to implement the connection terminal structure in the back surface direction since there is no member for supporting the back surface of the main body 101 or only the peripheral portion of the back surface of the main body 101 is extended.

The frame 105 of the present invention can simultaneously use a rigid frame 1051 and a frame 1053 made of a soft material. It is possible to easily detach the main body 101 while maintaining the shape of the frame 105 and to prevent the position of the connection pin from being fixed by placing the flexible substrate 186 at the position where the rigid frame 105 is located .

The guide protrusion 1058 and the guide groove 1013 may be formed as shown in FIGS. 4 and 5 to align the position of the connection pin 183 with the connection clip 188. The position of the guide groove 1013 and the guide projection 1058 can be mutually changed and the main body 101 is inserted into the frame 105 from the top to the bottom (z-axis direction) And the guide protrusion 1058 may also be formed long in the longitudinal direction so as not to interfere with the engagement between the main body 101 and the frame 105.

It is possible to form an acoustic hole 1055 through which the sound output from the acoustic output section 152 escapes while the connection clip 188 is formed. Acoustic holes 1055 can be formed in the rigid frame 105 and formed in the soft molded article 1053 as shown in Fig. One side of the flexible molded article 1053 is disposed adjacent to the rigid frame 105 so that the position between the acoustic hole 1055 of the frame 105 and the acoustic output section 152 of the main body 101 is changed .

7 is an exploded perspective view showing a flexible board 186, a first frame 1051 and a second frame 1052 of the wearable terminal 100 according to the present invention. FIG. 8 is an exploded perspective view showing a wearable terminal 100 ) Of the connection clip 188 of the flexible substrate 186 of the first embodiment.

7, one side of the flexible substrate 186 is coupled to insert the connection clip 188 through a pinhole formed in the first frame 1051, and the second frame 1052 is coupled from the outside to the first And may be configured to be sandwiched between the frame 1051 and the second frame 1052. [

One end of the flexible substrate 186 is mounted with a connection clip 188 on one side and a reinforcing plate 189 on the other side for supporting the connection clip 188 as shown in Fig. .

In order to form the flexible molded article 1053 after the flexible substrate 186 is fixed to the first frame 1051, there is a problem that the injection molded article is broken by the injection pressure during the double injection, The reinforcing plate 189 having rigidity like the US can be attached.

A coupling protrusion 1057 and a coupling hole 1867 may be provided to fix the flexible substrate 186 to the frame and fix the position of the flexible substrate 186. [ A coupling protrusion 1057 protruding from the first frame 1051 and a coupling hole 1867 formed corresponding thereto may be formed on the flexible substrate 186 and the reinforcing plate 189 as shown in FIG. An engaging hole 1867 corresponding to the engaging projection 1057 may be formed to fix the second frame 1052 as well.

Conversely, the fixing protrusion 1869 protruding from the flexible substrate 186 protrudes in the same direction as the connecting pin and can be inserted into the fixing groove 1059 formed in the first frame 1051. The fixing protrusions 1869 and the fixing grooves 1059 are positioned so as to be spaced apart from each other in the longitudinal direction of the coupling holes 1867 and the coupling protrusions and the flexible substrate 186 to allow the flexible substrate 186 and the frame 105 to be stably coupled .

The flexible substrate 186 is moved to the first frame (not shown) before the flexible projections 1053, the coupling holes 1867, the fixing projections 1869, and the fixing grooves 1059 are used to cover the flexible projections 1053 without using any adhesive. It is possible to prevent the flexible substrate 186 from being moved by the injection pressure when the flexible molded product 1053 is injected.

The first frame 1051, the flexible substrate 186, and the second frame 1052 may be combined and then inserted into a mold to form the soft molded article 1053. The rigid frames 1051 and 1052 and the flexible projections 1053 made up of the first frame 1051 and the second frame 1052 are made of different materials so that the flexible projections 1053 are attached to the rigid frames 1051 and 1052, Can be roughened. When the flexible injection molding is formed to be thin to reduce the size of the frame 105, the flexible injection molding 1053 may be dropped. Particularly, as shown in FIG. 5, the soft injection molded article 1053 in which the acoustic hole 1055 is formed may have a small thickness, causing a problem of falling off the rigid frame.

In order to prevent this, an engaging concavity 1056 is formed at a portion where the soft molded article 1053 having a thin thickness d, such as the acoustic hole 1055, is joined to increase the surface area. The coupling force between the flexible molded product 1053 and the rigid frames 1051 and 1052 can be improved while the flexible molded product 1053 is inserted between the coupling concavities 1056.

FIG. 9 is a view showing a connection clip 188 of the wearable terminal 100 according to the present invention. FIG. 10 is a view showing a connection clip 188 of the wearable terminal 100 related to the present invention and a conventional connection pin Fig. The connection clip 188 of the present invention is positioned on the inner side of the frame and is directed laterally. The main body 101 is inserted into the seat portion of the main body 101 of the frame in the thickness direction of the main body 101 and the connecting pin 183 is inserted from the upper side to the lower side in the figure and comes into contact with the connecting portion 1883 .

The connection clip 188 can be formed by bending one metal plate member. The connection clip 188 includes a base 1881 fixed to the flexible substrate 186 and connected to a conductive pattern formed on the flexible substrate 186, a connection portion 1883 protruding through the pinhole of the first frame 1051, And links 1882 and 1884 connecting the connection portion 1881 and the connection portion 1883.

The link has a curved line and is a part whose shape is changed corresponding to the change of the position of the connection part 1883 when the connection pin 183 contacts the connection part 1883. The link of the present invention includes a first link 1882 bent in a U-shape at the base 1881 and a second link 1884 bent in an S-shape.

Figs. 10 (a) and 10 (b) are conventionally used connection clips, and the link includes only the U-folded link 2. In the conventional connection clip, as shown in FIG. 10A, the base 1 is disposed on the bottom surface so that the connecting portion 3 protrudes upward, and the connecting pin approaches and contacts from the upper side to the lower side. That is, the connecting portion 1883 of the connecting clip is retracted as much as the protruding portion, at which time a specific portion A of the link portion of the connecting clip is deformed.

However, when the connecting clip is arranged in the lateral direction as shown in Fig. 10 (b) and the connecting pin opposing from the upper side to the lower side is inserted, deformation occurs at a position B different from the portion (A) Occurs. The portion B where the deformation occurs is disposed adjacent to the connection portion 1883 than the portion A of Fig. 10 (a). At this time, since the position of the deformed portion of the connecting clip is smaller as the distance from the connecting portion 1883 is, the deformed portion B in the arrangement as shown in (b) (A < b).

That is, there is a problem that the durability of the connection clip is deteriorated because the fatigue of the connection clip increases. In order to solve the above problem, the present invention additionally adds an S-shaped second link 1884 to separate the folded position C from the connecting portion 1883. The second link 1884 is characterized in that the position of the deformed portion C is further separated from the connecting portion 1883 by bending the link located adjacent to the existing connecting portion 1883 in the direction of the base 1881.

The deformation degree of the deformed portion C of Fig. 9 (b) is smaller than that of the deformed portion B of Fig. 10 (b), and the fatigue applied to the connecting clip 188 can be reduced. (b> c)

The first cover 1886 covers a portion of the second link 1884. The second link 1884 is bent in the direction of the base 1881 so that the connecting pin 183 is prevented from being drawn into the second link 1884 portion and the second link 1884 is damaged prevent.

In the conventional connection clip shown in Fig. 10 (a), the connection end portion 8 is opened, so that the foreign matter enters the end portion 8 of the connection portion or the end portion 8 is caught, and the connection portion can be deformed. To prevent this, the connection clip 188 of the present invention may further include a second cover 1887 that covers the end 1888 of the connection, as shown in FIG. 9 (a). It is possible to prevent the connection portion from being excessively projected by bending the end portion 1888 of the connection portion so that the end portion 1888 of the connection portion is located inside the second cover 1887. [ The first cover 1886 and the second cover 1887 can be formed by bending the end of the side wall portion 1885 extending from the base 1881. [

11 is a cross-sectional view showing a coupling detection sensor 145 of the wearable terminal 100 according to the present invention. Since the main body 101 is detached from the frame 105, there is a risk that the main body 101 may be accidentally lost and lost if it is misaligned. The coupling detection sensor 145 of the present embodiment may further include a magnet 1451 and a Hall sensor 1452. The coupling sensor 145 may detect whether or not the main body is detected in the frame 105, .

The hall sensor 1452 senses a magnetic field. When the magnet 1451 approaches, the Hall sensor 1452 senses the magnetic field of the magnetic field, generates a signal, and transmits the signal to the main substrate 185. The hall sensor 1452 must be connected to the main board 185 and may be positioned on the main body 101 side and the magnet 1451 may be positioned on the side of the frame 105.

The magnet may be located in the magnet housing 1054a protruding from the inside of the frame 105, and may further include a cap 1054b covering the magnet so that the magnet is not seen. The back surface of the main body 101 may include a recessed portion corresponding to the protruded portion due to the magnet housing 1054a.

When the Hall sensor 1452 senses that the magnet 1451 is separated from the Hall sensor 1452, the user can notify the user of the state that the main body is detached from the frame 105 through the sound output unit 152 or the display unit 151, .

12 and 13 are views showing another embodiment of the coupling detection sensor 145 of the wearable terminal 100 of the present invention. When the connection pin 183 and the connection clip 188 are coupled using the connection pin 183 provided in the main body and the connection clip provided in the frame, it is possible to detect an engagement and generate an alarm if the connection is disconnected.

However, if an antenna or a ground is formed on the flexible substrate and connected to the connection clip 188, if the connection pin 183 and the connection clip 188 are used as the coupling detection sensor 145, the properties of the antenna may be changed A separate sensing pin 1453 and a sensing clip 1458 may be provided.

The sensing clip 1458 may have the same structure as the connection clip 188 described above because the sensing clip 1458 may have poor durability when it contacts the main body 101 that is coupled in the thickness direction of the main body.

The sensing clip 1458 separated from the connection clip 188 is not connected to the flexible substrate 186 and does not affect the performance of the antenna. In addition, since only one line connected to the sensing pin 1453 needs to be added to the main board 185, there is an advantage that the space occupied by the actual coupling detection sensor 145 is not large.

When the sensing clip 1458 is detached from the sensing pin 1453, the main board 185 senses the sensing clip 1453 and informs the user that the main body 101 is connected to the frame 105 through the sound output unit 152 or the display unit 151, You can notify the situation that has been diverted from.

As described above, according to at least one embodiment of the present invention, the function of the main body 101 can be expanded by incorporating electronic parts in the band 102 in the detachable wearable terminal 100. In addition, the shape of the connection clip 188 between the main body 101 and the frame 105 is improved to improve durability.

In addition, it is possible to prevent the risk of loss by sensing that the main body 101 is separated from the frame 105.

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.
