To provide a high voltage component protection structure which can prevent exposure of a live part of a high voltage component without depending on a shape of the live part.SOLUTION: A high voltage component protection structure includes: a motor 10 having a housing 11 attached to an electric vehicle and a live part 12 located in the housing 11; a foam jet device 20 which jets a liquid foam plastic and a hardening agent to form a foam 40 in a space between the live part 12 and the housing 11; and collision detection means 30 which detects a collision body 50 colliding with the electric vehicle. The foam jet device 20 forms the foam 40 when the collision is detected by the collision detection means 30.SELECTED DRAWING: Figure 2
【課題】高電圧部品の活電部の形状に依存せずに、活電部の露出を防ぐことができる高電圧部品の保護構造を提供する。【解決手段】電気自動車に取り付けられる筐体11及び筐体11の内部に活電部12を有するモーター10と、活電部12と筐体11との間の空間に、液状の発泡プラスティック及び硬化剤を噴出して発泡体40を形成する発泡体噴出器20と、電気自動車に衝突体50が衝突したことを検出する衝突検出手段30と、を備え、発泡体噴出器20は、衝突検出手段30により衝突が検出されたときに、発泡体40を形成する。【選択図】図2
