Abstract

L'invention concerne une charnière à ressort à économie d'énergie, comprenant un premier bras de charnière (1) et un second bras de charnière (2). Le premier bras de charnière a une structure en forme de U. Un arbre de rotation (12) et un arbre de support de limitation (13) sont disposés côte à côte sur le premier bras de charnière. Le second bras de charnière a une structure de gorge en forme de U. Le second bras de charnière est relié en rotation au premier bras de charnière en utilisant l'arbre de rotation en tant que point de pivot. Des gorges de limitation (21), correspondant à l'arbre de support de limitation, sont prévues sur les parois latérales du second bras de charnière. Un mécanisme de mandrin élastique (3) relié perpendiculairement à l'arbre de support de limitation est prévu dans le second bras de charnière. Les deux parois latérales gauche et droite du second bras de charnière sont disposées sur la face latérale interne des deux parois latérales du premier bras de charnière. La paroi inférieure du second bras de charnière est pourvue de parties de fixation (241, 242) s'étendant hors des deux parois latérales gauche et droite du second bras de charnière. Les parties de fixation sont pourvues de trous de fixation de vis (243, 244). Des parties saillantes formant un espace (221, 231), respectivement cintrées vers l'extérieur, sont respectivement prévues aux positions où les deux parois latérales gauche et droite du second bras de charnière correspondent aux trous de fixation de vis. Dans la présente charnière, si l'on considère que l'on ne change pas les positions du trou d'installation de la charnière à ressort existante, la taille du second bras de charnière peut être réduite de manière à économiser de la matière de manière efficace et à réduire les coûts. Les parties de fixation, qui s'étendent hors des deux parois latérales gauche et droite du second bras de charnière et sont pourvues de trous de fixation de vis, situés sur la paroi de fond du second bras de charnière, empêchent tout changement de la position et de la taille des trous d'installation et s'adaptent à un ensemble normalisé.
