The invention discloses a supporting phase bearing self-locking
lower limb rehabilitation device, and relates to the technical field of
rehabilitation training devices. The supporting phase bearing self-locking
lower limb rehabilitation device comprises a
waist and
crotch structure, a
thigh structure, a
knee joint mechanism, a shank structure and a shoe body which are sequentially arranged from top to bottom, and a steel
wire rope adjusting mechanism used for adjusting the pay-off length of a steel
wire rope is arranged on the
waist and
crotch structure; and the top end of the
thigh structureis rotationally connected with the
waist and
crotch structure, the bottom end is fixedly connected with the
knee joint mechanism, the top end of the shank structure is fixedly connected with the kneejoint mechanism, and the bottom end is connected with the shoe body through a spring. A steel
wire rope can be used for driving a chuck to rotate and be tensioned to enable chuck clamping teeth to beengaged with output disc clamping teeth, structural self-locking of the
knee joint mechanism is achieved when a user is in a supporting phase, the steel wire
rope can be loosened through the
thigh lifting action of the user in a pre-swinging phase, and the chuck rotates under the elastic force effect of a torsional spring and is disengaged from structural self-locking of an output disc, so that the motor is used for supplying power to provide knee
joint action assistance, the locking state is reliable and stable, safety is high, and overall
energy consumption is low.
