Abstract

L'invention concerne un composant de charnière et un dispositif de réfrigération le comprenant. Le composant de charnière comprend un premier élément de charnière, un second élément de charnière et un composant de pièce coulissante ; le premier élément de charnière et le composant de pièce coulissante coopèrent l'un avec l'autre au moyen d'un premier ensemble de rotation et d'un premier ensemble de limitation, et le second élément de charnière et le composant de pièce coulissante coopèrent l'un avec l'autre au moyen d'un second ensemble de rotation et d'un second ensemble de limitation ; lorsque le composant de charnière est dans un processus d'ouverture, le second élément de charnière verrouille le composant de pièce coulissante au moyen du second ensemble de limitation, le second élément de charnière et le composant de pièce coulissante tournent ensemble in situ par rapport au premier élément de charnière au moyen du premier ensemble de rotation, et ensuite le premier ensemble de limitation agit sur le composant de pièce coulissante pour le déplacer simultanément par rapport au premier élément de charnière et au second élément de charnière ; et le premier élément de charnière verrouille le composant de pièce coulissante au moyen du premier ensemble de limitation, et le second élément de charnière déverrouille le composant de pièce coulissante au moyen du second ensemble de limitation, puis le second élément de charnière tourne in situ par rapport au composant de pièce coulissante au moyen du second ensemble de rotation. La présente invention permet de commander efficacement la séquence de deux rotations in situ, ce qui permet de commander efficacement la trajectoire de mouvement d'un corps de porte.
