Abstract

L'invention concerne un ensemble touche, un clavier et un terminal mobile. L'ensemble touche comprend un substrat (10), un capuchon de touche (70), et un ensemble de levage (50) pour amener le capuchon de touche (70) à monter. L'ensemble de levage (50) comprend : des supports de levage (51, 52) articulés respectivement au capuchon de touche (70) et au substrat (10); une plaque coulissante (30), la plaque coulissante (30) pouvant coulisser par rapport au substrat (10) et étant verrouillés dans une position définie; et un ensemble d'entraînement et de verrouillage relié à la plaque coulissante (30) et au capuchon de touche (70) ou aux supports de levage (51, 52). Lorsque la plaque coulissante (30) est dans une seconde position réglée, l'ensemble d'entraînement et de verrouillage est dans une position de fonctionnement verrouillée, et le capuchon de touche (70) est verrouillé dans une position dans laquelle il est pressé. Lorsque l'ensemble d'entraînement et de verrouillage est dans une position de verrouillage, le capuchon de touche (70) peut être tiré vers le bas jusqu'à une position dans laquelle le capuchon de touche (70) est pressé vers le bas, et le capuchon de touche(70) est verrouillé. A ce moment, la hauteur de l'ensemble du clavier peut être réduite de manière à faciliter l'amincissement du clavier, facilitant ainsi l'amincissement de l'ensemble du terminal mobile.
