Abstract

Une charnière à amortissement améliorée comprend un logement (1), un premier arbre rotatif (51), une broche en forme de U (21), une coupelle de charnière (2) et un premier élément de liaison (3). La coupelle de charnière (2) est fixée sur un panneau de porte. La charnière à amortissement améliorée comprend également un second arbre rotatif (52), un ressort de torsion (4) et un second élément de liaison (5). Un élément de guidage d'amortisseur comprend une structure de guidage (6) située entre le second élément de liaison (5) et le logement (1). Un amortisseur (8) est situé entre un bloc de positionnement (7) et la structure de guidage (6). Le bloc de positionnement (7) comporte un trou traversant (71). Une tige de piston (82) de l'amortisseur (8) traverse le trou traversant (71) et s'étend vers le ressort de torsion (4). Une extrémité du second élément de liaison (5) est reliée en entraînement à la structure de guidage (6). Les coûts de production de la charnière sont efficacement réduits. De plus, l'invention supprime le bruit acoustique produit par le frottement entre les composants et améliore la régularité générale de la rotation du produit, ce qui augmente la qualité globale et accroît la compétitivité du produit sur le marché.
