본 발명에 의하면, 플렉서블 배터리의 나머지 양단은 제1 밴드 부재 및 제2 밴드 부재 각각에 수용된다. 즉, 하나의 플렉서블 배터리가 몸체 부재, 제1 밴드 부재 및 제2 밴드 부재 내부에 걸치도록 내장된다. 이에 따라 본 발명에 따른 웨어러블 장치는 일반적인 배터리가 몸체 부재에만 내장된 웨어러블 장치와 비교하여 상기 플렉서블 배터리의 크기가 증가될 수 있다. 따라서, 상기 플렉서블 배터리의 축전 용량도 증가되어 본 발명의 일실시예에 따른 웨어러블 장치의 사용시간을 증가시킬 수 있다.According to the present invention, the remaining both ends of the flexible battery is accommodated in each of the first band member and the second band member. That is, one flexible battery is built to span the body member, the first band member, and the second band member.

그리고, 종래의 유선 충전 방식에서 충전 케이블을 연결하기 위한 필수 구성인 충전 포트가 구비되지 않아도 됨으로써, 이물질 및 수분에 의한 고장을 방지할 수 있다. 그러므로, 사용자는 웨어러블 장치의 취급 및 관리가 매우 용이해질 수 있다. In addition, since the charging port, which is an essential component for connecting the charging cable in the conventional wired charging method, does not need to be provided, it is possible to prevent a failure due to foreign matter and moisture. Therefore, the user can be very easy to handle and manage the wearable device.

한편, 도 11 내지 도 12를 참조하면, 전술한 플렉서블 배터리(140)는 일례로 전극조립체(141) 및 외장재(147, 148)를 포함하며, 상기 전극조립체(141)는 전해액과 함께 외장재(147, 148)의 내부에 봉지된다.Meanwhile, referring to FIGS. 11 to 12, the aforementioned flexible battery 140 includes, for example, an electrode assembly 141 and exterior materials 147 and 148, and the electrode assembly 141 includes an exterior material 147 together with an electrolyte solution. 148 is sealed inside.
이때, 상기 전극조립체(141) 및 외장재(147, 148)는 길이방향에 대한 수축 및 이완을 위한 패턴(146, 149)이 각각 구비되며, 상기 외장재(147, 148)에 형성되는 제1패턴(149)과 상기 전극조립체(141)에 형성되는 제2패턴(146)이 서로 동일한 방향성을 갖도록 구비된다.In this case, the electrode assembly 141 and the exterior members 147 and 148 are provided with patterns 146 and 149 for contraction and relaxation in the longitudinal direction, respectively, and are formed on the exterior members 147 and 148. 149 and the second pattern 146 formed on the electrode assembly 141 are provided to have the same directivity.
이를 통해, 상기 전극조립체(141) 및 외장재(147, 148)를 구성하는 기재 자체의 변형량이 방지되거나 최소화되므로 밴딩이 발생하더라도 휘어지는 부분에서 일어날 수 있는 기재 자체의 변형량이 최소화됨으로써 전극조립체(141) 및 외장재(147, 148)가 파손되거나 성능이 저하되는 것을 방지할 수 있게 된다.As a result, since the amount of deformation of the substrate constituting the electrode assembly 141 and the exterior members 147 and 148 is prevented or minimized, the amount of deformation of the substrate itself may be minimized even if bending occurs, thereby the electrode assembly 141. And exterior materials 147 and 148 can be prevented from being damaged or deteriorated.
이때, 상기 제1패턴(149) 및 제2패턴(146)은 서로 동일한 방향성뿐만 아니라 제1패턴(149)과 제2패턴(146)이 서로 일치하도록 배치된다. 이는, 상기 제1패턴(149)과 제2패턴(146)이 항상 동일한 거동이 일어날 수 있도록 하기 위함이다.In this case, the first pattern 149 and the second pattern 146 may be disposed so that the first pattern 149 and the second pattern 146 coincide with each other as well as the same direction.
