Abstract

L'invention porte sur un ensemble charnière de porte, comprenant un premier engrenage (101), un second engrenage (102) et un ensemble d'encliquetage (5). Le premier engrenage (101) est disposé sur une porte primaire (6) au moyen d'une première plaque de charnière (3) ; le second engrenage (102) est en prise avec le premier engrenage (101), et le second engrenage (102) est disposé sur la porte primaire (6) ; l'ensemble d'encliquetage (5) est disposé sur une porte secondaire (7), et l'ensemble d'encliquetage (5) est relié au second engrenage (102) au moyen d'une seconde plaque de charnière (4). Lorsque la porte primaire (6) est ouverte, le premier engrenage (101) est en prise avec le second engrenage (102), le second engrenage (102) entraîne la seconde plaque de charnière (4) pour monter, et l'ensemble d'encliquetage (5) est dans un état d'encliquetage, de telle sorte que la porte secondaire (7) se déplace en synchronisation avec la porte primaire (6). L'invention concerne également un corps de réfrigérateur de type porte-dans-porte. Lorsqu'une porte primaire est ouverte, une porte secondaire peut être automatiquement verrouillée, et lorsque la porte primaire est fermée, la porte secondaire peut être automatiquement déverrouillée, ce qui permet de résoudre le problème d'inconvénient pour les utilisateurs à accéder à des articles, et d'améliorer leur expérience d'utilisation.
