The present invention relates to a gait rehabilitation device, which comprises two sets of exoskeleton mechanisms. Each of the exoskeleton mechanisms comprises: a thigh base, a thigh frame body, a hip joint mechanism, a thigh adjusting mechanism, a calf frame body, a knee joint mechanism, a calf adjusting mechanism, a foot pedal and an ankle joint mechanism. The hip joint mechanism is mounted between the thigh base and the thigh frame body to drive the thigh frame body pivotally swinging with respect to the thigh base. The thigh adjusting mechanism is used for adjusting the length of the thigh frame body. The knee joint mechanism is mounted between the thigh frame body and the calf frame body to drive the calf frame body pivotally swinging with respect to the thigh frame body. The calf adjusting mechanism is used for adjusting the length of the calf frame body. Thus, the present invention may simulate the gait trajectory of a person while walking on a level ground, so as to effectively achieve the walking rehabilitation effect.本發明係一種步態復健器,包括二組外骨骼機構,各該外骨骼機構係包括:一大腿基座、一大腿架體、一髖關節機構、一大腿調整機構、一小腿架體、一膝關節機構、一小腿調整機構、一足底踏板以及一環關節機構,該髖關節機構係裝設於該大腿基座以及該大腿架體間以驅動該大腿架體相對於該大腿基座樞擺,該大腿調整機構係調整該大腿架體的長度,該膝關節機構係裝設於該大腿架體以及該小腿架體間以驅動該小腿架體相對於該大腿架體樞擺,該小腿調整機構係調整該小腿架體的長度;藉此能夠模擬人體平地行走的步態軌跡,而有效提供復健行走的效果。10...骨盆重心調整機構11...連接架20...外骨骼機構21...大腿基座221...大腿支架222...小腿基座23...髖關節機構24...大腿調整機構251...小腿第一支架252...小腿第二支架26...膝關節機構27...小腿調整機構28...足底踏板281...側板282...底板283...滑輪29...踝關節機構
