Abstract

L'invention concerne un chariot à bagages pliant pouvant se déplier pour former une bicyclette, comprenant une roue avant, une tige pouvant se déployer et se plier, un ensemble de direction (1), une roue arrière, un siège pliant et dépliant, un ensemble d'entraînement (2) et un ensemble intermédiaire de cadre pliant à quatre tiges de liaison (3). Une tige pouvant se déployer et se replier (7) et une tige de siège peuvent être tirées de la partie inférieure et verrouillées. Lorsque l'ensemble de cadre intermédiaire pliant à quatre tiges de liaison (3) est replié et ramené à la largeur du chariot à bagages, les ensembles avant et arrière (1, 2) reliés à ce dernier sont parallèles, et lorsqu'il est déplié pour former le cadre de bicyclette, les ensembles avant et arrière (1, 2) forment respectivement un angle d'inclination requis avec le sol, une forme trapézoïdale stable. Le chariot peut être porté de manière commode par un voyageur et transporter des bagages relativement lourds sur un parcours, et peuvent également être dépliés pour former une bicyclette de voyage portable le cas échéant. En outre, la position du cadre est relativement basse, ce qui facilite la conduite et l'utilisation par des femmes tout en répondant aux exigences précitées, et permet d'atteindre les effets et les objectifs d'un volume compact et portable après repliement, et d'un stockage commode.
