Claims (5)
1. Elément anti-explosion de batterie, comprenant un corps (20) d'élément antiexplosion relié à un boîtier de batterie qui est muni d'une chambre de logement, dans lequel le corps (20) d'élément anti-explosion fait saillie vers le haut pour former une partie de détente de pression (21) ; la partie de détente de pression (21) présente une position de détente de pression (30) ; et par l’intermédiaire d'un éclatement radial ou axial de la position de détente de pression (30), le corps (20) d'élément anti-explosion libère une pression supérieure à la résistance à la compression de la position de détente de pression (30).
2. Elément anti-explosion de batterie selon la revendication 1, dans lequel le côté intérieur de la partie de détente de pression (21) communique avec la chambre de logement du boîtier de batterie.
3. Elément anti-explosion de batterie selon la revendication 1, dans lequel la face d'extrémité inférieure du corps (20) d'élément anti-explosion et la face intérieure de la partie de détente de pression (21) sont soudées à la partie supérieure du boîtier de batterie.
4. Elément anti-explosion de batterie selon la revendication 1, dans lequel le corps (20) d'élément anti-explosion est rond.
5. Elément anti-explosion de batterie selon la revendication 1, dans lequel la jonction de la partie de détente de pression (21) et du corps (20) d'élément anti-explosion présente un radian, pour permettre à la partie de détente de pression (21) d'être en liaison sans inflexion avec le corps (20) d'élément anti-explosion.
