The invention discloses a passive
rehabilitation training device for double lower limbs. The passive
rehabilitation training device comprises a base frame, a motor, a
speed reduction device, a driving gear, a driven gear, a gear shaft, four groups of eccentric wheels,
thigh and shank lever supports and a floating bracket
assembly. A motor drives a
gear system to drive a
right thigh eccentric wheel, a right shank eccentric wheel, a
left thigh eccentric wheel and a left shank eccentric wheel to rotate synchronously, and the left and right eccentric wheels have a 180-degree
phase difference in the circumferential direction, so that corresponding lever supports are pushed to achieve alternate flexion and extension movement of two legs, and the natural
gait of the
human body is simulated. The floating bracket
assembly and the front end of the lever form a rotating pair through a pin, the supporting plate is allowed to slightly float in the vertical direction and the horizontal direction so as to adapt to different body types and
muscular tension changes, and the man-
machine suitability and the use comfort are improved. The device is compact in structure, full-mechanical in transmission, stable in operation, low in cost and suitable for postoperative
early rehabilitation and
lower limb passive activity promotion of long-term bedridden patients and sedentary people.
