Abstract | A magnetic field shielding module for an electric vehicle is provided. A magnetic field shielding module for an electric vehicle according to an embodiment of the present invention may comprise: a main shielding layer including a plurality of unit blocks made of a ferrite material to shield a magnetic field generated from a planar coil in which a conductive member is wound multiple times, the main shielding layer being formed in a plate shape having a predetermined area by the plurality of unit blocks arranged adjacent to each other; and an auxiliary shielding layer made of a magnetic material containing a metal component to supplement the main shielding layer, disposed on one surface of the main shielding layer, and including a penetrating portion formed in a shape corresponding to that of the planar coil.
L'invention concerne un module de blindage de champ magnétique pour un véhicule électrique. Un module de blindage de champ magnétique pour un véhicule électrique selon un mode de réalisation de la présente invention peut comprendre : une couche de blindage principale comprenant une pluralité de blocs unitaires constitués d'un matériau de ferrite servant à assurer une protection contre un champ magnétique généré à partir d'une bobine plane dans laquelle un élément conducteur est enroulé plusieurs fois, la couche de blindage principale étant formée avec une forme de plaque ayant une superficie prédéfinie par les blocs de la pluralité de blocs unitaires disposés adjacents les uns aux autres; et une couche de blindage auxiliaire constituée d'un matériau magnétique contenant un constituant métallique servant à compléter la couche de blindage principale, disposée sur une surface de la couche de blindage principale, et comprenant une partie pénétrante formée avec une forme correspondant à celle de la bobine plane.
전기자동차용 자기장 차폐모듈이 제공된다. 본 발명의 일 실시예에 따른 전기자동차용 자기장 차폐모듈은 도전성부재가 복수 회 권선된 평판형코일에서 발생하는 자기장을 차폐할 수 있도록 페라이트 재질로 이루어진 복수 개의 단위블럭들을 포함하고, 상기 복수 개의 단위블럭들이 서로 인접하도록 배열되어 소정 면적을 갖는 판상으로 형성되는 메인차폐층; 및 상기 메인차폐층을 보완할 수 있도록 금속성분을 포함하는 자성재질로 이루어지고, 상기 메인차폐층의 일면에 배치되며, 상기 평판형코일과 대응되는 형상으로 관통형성되는 관통부를 포함하는 보조차폐층;을 포함할 수 있다. |
