DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a preferred embodiment of a wearable smart watch in which a wireless charging module is mounted on a band according to the present invention will be described in detail with reference to the accompanying drawings.

Referring to FIG. 1, a wearable smart watch 100 according to an embodiment of the present invention includes a main body 110 on which a base module 102 is mounted, and a bending or stretching band 120. A battery 112 for supplying power to the base module 110 is mounted on the band 120. The battery 112 is also flexible along with the band 120.

The base module 102 includes a conventional semiconductor package for operating a display or communication or other smart watch. Thus, the base module 102 of the body 110 includes all the modules that enable smart devices such as smart phones, personal digital assistants (PDAs), handheld PCs, mobile phones, and the like, can do.

The battery 112 may be WPC technology for wireless power transmission. Since the smart watch 100 is used while being worn on the wrist, water tightness should be substantially ensured. To charge the wired cable, the port where the charge jack is inserted must be opened, but the port is a waterproof obstacle. Accordingly, it is preferable that the wearable smart watch 100 is provided with a wireless charging function by omitting a port for watertightness.

The battery 112 of the present invention includes a wireless charging reception module 114 for receiving electromagnetic waves from a wireless charging transmission module (not shown) and a capacitor module (not shown) for storing electric energy generated in the wireless charging reception module 114 116).

In the present invention, the wireless charge receiving module 114 may be provided in the form of a COB package. For example, in the COB package 10 of the present invention, the IC chip 12 and the antenna tag 14 are integrally formed on a chip on board (COB) basis. The COB package 10 may be formed by stacking at least two COB sheets in order to increase the operating frequency.

The COB package 10 includes a flexible substrate 16, an antenna tag 14 formed on the flexible substrate 16 and a protection member 18 having insulation and adhesiveness for protecting the antenna tag 14 do. For example, the protective member 18 may include a sticky protective member made of a silicon material or a polymer material. Antenna tag 14 is an annular coil in the form of a circle or square and can receive electromagnetic waves that are wirelessly output at a frequency of approximately 150 KHz from a wireless charging transmission module (not shown) of a charger (see FIG. 7). For example, the antenna tag 14 may include a conductive film formed using soft copper, titanium, or aluminum by a photolithography process or a printing process.

The IC chip 12 may include a rectifier, a regulator, a modulator, and an MCU for effective wireless charging. A bonding layer to be connected to the capacitor module 116 may be formed on one side of the antenna tag 14.

The flexible substrate 16 can be designed to be flexible so as to be bent or folded. For this, the flexible substrate 16 may be formed of a polymer material. For example, it may be formed of polyimide (PI), polyester, polyethylene naphthalate (PEN), Teflon, polyethylene terephthalate (PET) or other polymeric.

The capacitor module 116 may be a secondary battery capable of repeated charge and discharge or an electric double-layer capacitor (EDLC) capacitor made of carbon. However, in the present invention, in order to apply a capacitor to a band 120 having a large surface area and a thin thickness, it is preferable to use an electric double layer capacitor 30 in which an activated carbon electrode is disposed with a separator interposed therebetween. Moreover, the electric double layer capacitor 30 is advantageous to realize the flexible band 120. [

The electric double layer capacitor 30 is provided on the flexible substrate 32 and covers a side surface of the electrode 36 and a pair of electrodes 36 disposed above and below with the insulating separator 34 therebetween, An insulator 38 for dividing the electrode 36 and a pair of conductive metal covers 42 for performing a current collection function and covering the upper and lower portions of the electrode 36 by a conductive binder.

The electrode 36 may be an activated carbon electrode into which an electrolytic solution has permeated. As the separator 34, an ion permeable polypropylene or other porous material may be used. As the insulator 38, a glass having excellent insulating properties can be used. The metal cover 42 may be formed of a flexible aluminum foil having excellent current collecting property.

The flexible substrate 32 can be designed to be flexible so as to be bent. A polymer film may be used. The polyethylene naphthalate (PEN) or the polyethylene terephthalide (PET) is flexible and suitable for the flexible substrate 32.

The flexible substrate 16 of the COB package 10 and the flexible substrate 32 of the electric double layer capacitor 30 can be used substantially the same.

For this, a structure in which the COB package 10 and the electric double layer capacitor 30 are arranged vertically as shown in FIGS. 3A and 3B is advantageous as shown in FIGS. 2A and 2B. That is, the rigid region and the flexible region are repeatedly arranged, so that the band 120 can bend or bend naturally around the soft region.

Referring to FIG. 4, a plurality of rigid bands of the band 120 may be coupled through a hinge pin, a hinge, or the like to be bent. The rigid bands are connected in a block-type manner, and the bending band can be realized by designing that each block band can be rotated at a certain angle. When a plurality of nodes are formed in this way, the band 120 can be bent or bent at any time even if it is not ductile.

Referring to Figure 5, the band 120 described above is interchangeable. The band 120 itself can be replaced from the main body 110 and a plurality of batteries 112 are mounted on the band 120 and the band 120 on which the battery 112 is mounted can be detachably attached to the main body 110 have.

To this end, the smart watch 100 of the present invention includes a main body 110 and a band 120, a connector 130 for electrically connecting the main body 110 and the band 120, (Not shown). Therefore, the coupler 140 connecting the main body 110 and the band 120 can be disassembled and the band 130 can be removed by separating the connector 130.

The connector 130 may be configured as a pair of protruding and depressed connectors so that the band 120 is electrically connected to the main body 110. The connector 130 allows the battery 112 of the band 120 to provide power to the base module 102 of the body 110. At this time, the joint portion of the connector 130 may be subjected to silicone or rubber molding for waterproofing.

The coupler 140 may be configured as a pair of hooks such that the band 120 is not separated from the body 110 at all.

Since the bands 120a and 120b are fastened to both sides of the main body 110 when the left and right pair of the bands 120 are fastened to each other using the buckle, The power is continuously supplied even if the other band 120b is disconnected from the main body 110. Therefore, when the battery 112 is exchanged, the power can be maintained through the one band 120a, Not required.

Referring again to Figure 1, the band 120 may exhibit stretchability through an integral flexible band. The bending or folding band 120 may be formed of a flexible polymeric material or rubber. May be formed of polyimide in the polymer. When the flexible band is formed of such a material, tensile stress or compressive stress is applied to the semiconductor package or the semiconductor die so that it is not damaged even if the flexible band is bent.

On the other hand, it is possible to provide an extra battery band and design it so that it can be replaced with a used band after charging. In particular, when the smart watch 100 is used for a game purpose, the battery 112 is consumed in a large amount. At this time, it is necessary to supply power through a separate independent band 320.

The independent band 320 may be separated from the main body 110 or the band 120 of the main smart watch 100. In this case, Can be designed to be fastened.

6, the band-independent wearable smart device 300 includes a main smart watch 100 composed of a main body 110 and a band 120 and a main smart watch 100 installed on one side of the smart watch 100, Or an independent band 320 that is fastened to the band 120.

The independent band 320 includes one or more batteries 112. The independent band 320 may be a flexible, retractable closed ring (loop) type. The independent band 320 may be made of a polyimide material as described above.

Referring to FIG. 7, such a smart watch 100 or an independent band (320 of FIG. 6) can be charged using the charger P. When the charging is completed, the main smart watch 100 can be coupled to the main smart watch 100 as shown in FIG.

As described above, according to the present invention, it is possible to realize a high-capacity and high-wearable and wearable smart device by mounting a battery in a band and extending a communication module or a data processing module in a main body in which a battery is mounted . Many other modifications will be possible to those skilled in the art, within the scope of the basic technical idea of the present invention.
