Title (EN) ACTUATOR USING A SHAPE MEMORY ALLOY
(FR) ACTIONNEUR UTILISANT UN ALLIAGE À MÉMOIRE DE FORME
(KO) 형상기억합금 액츄에이터
Abstract: front page image
(EN) The present invention relates to an actuator using a shape memory alloy, comprising: a first member and a second member which are spaced apart from each other and arranged parallel to each other; a first shape memory alloy, both ends of which are coupled to the first member and to the second member, respectively; a second shape memory alloy, both ends of which are coupled to the first member and to the second member, respectively, and which intersects the first shape memory alloy; and a spring, both ends of which are coupled to the first member and to the second member, respectively. The thus-configured actuator of the present invention is advantageous in that power is required only at the moment of operating the actuator, thereby reducing power consumption and improving the reaction speed of the actuator.
(FR) La présente invention porte sur un actionneur qui utilise un alliage à mémoire de forme, lequel actionneur comprend : un premier élément et un second élément qui sont espacés l'un de l'autre et agencés parallèlement l'un à l'autre ; un premier alliage à mémoire de forme, dont les deux extrémités sont couplées au premier élément et au second élément, respectivement ; un second alliage à mémoire de forme, dont les deux extrémités sont couplées au premier élément et au second élément, respectivement, et qui croise le premier alliage à mémoire de forme ; et un ressort, dont les deux extrémités sont couplées au premier élément et au second élément, respectivement. L'actionneur ainsi configuré selon la présente invention est avantageux en ce que de l'énergie est requise uniquement au moment du fonctionnement de l'actionneur, de façon à réduire ainsi la consommation d'énergie et à améliorer la vitesse de réaction de l'actionneur.
(KO) 본 발명은 일정거리 이격되어 평행하게 배치되는 제1 부재와 제2 부재; 상기 제1 및 제2 부재 각각에 양단이 결합되는 제1 형상기억합금소자; 상기 제1 및 제2 부재 각각에 양단이 결합되며, 상기 제1 형상기억합금소자와 교차해서 배치된 제2 형상기억합금소자; 및 상기 제1 및 제2 부재 각각에 양단이 결합되는 스프링;을 포함하는 형상기억합금 엑츄에이터에 관한 것이다. 본 발명은 이러한 구성에 의해서, 엑츄에이터가 작동되는 순간에만 전원이 필요하다는 장점이 있어서 전원을 절약할 뿐 아니라 엑츄에이터 반응속도가 빨라지는 장점이 있다.
