A wheel-leg isomorphic transformable wheelchair exoskeleton robot, relating to a wheelchair exoskeleton robot. Said robot is used for rehabilitation training of a patient, and solves the problem in an existing wheel-leg medical rehabilitation lower-extremity exoskeleton robot of a difficulty in independent completion of structural transformation by a user due to inability of isomorphic unfolding and storage before and after the structural transformation of the wheelchair because of mechanism redundancy caused by relative independence of parts in a transformation process of a wheelchair moving mode structure and an exoskeleton rehabilitation training mode structure, as well as low degrees of light-weight and portability. Said robot comprises a waist part (1), a foldable wheelchair rack (4), two thighs (2), and two lower legs (3)； the waist part (1) comprises a low back assembly (1-1) and a wheelchair seat (1-8), and the wheelchair seat (1-8) is mounted on the low back assembly (1-1) and is rotatable with respect to the low back assembly (1-1)； the thighs (2) are connected to the low back assembly (1-1) by means of hip joints (45)； the thighs (2) are connected to the lower legs (3) by means of knee joints (46)； the foldable wheelchair rack (4) is rotatably connected to the hip joints (45) and the lower legs (3).L'invention concerne un robot exosquelette de type fauteuil roulant transformable isomorphique à jambe à roue, se rapportant à un robot exosquelette de type fauteuil roulant. Ledit robot est utilisé pour l'entraînement de rééducation d'un patient, et résout le problème dans un robot exosquelette de rééducation médicale à jambe à roue existant d'une difficulté dans l'achèvement indépendant de la transformation structurelle par un utilisateur en raison de l'incapacité de dépliage et de stockage isomorphes avant et après la transformation structurelle du fauteuil roulant en raison d'une redondance de mécanisme provoquée par l'indépendance relative de parties dans
