Abstract

The invention discloses a wearable lower-limb rehabilitation walking aid mechanical device which comprises a waist mechanism, thigh bodies, hip joint mechanisms, shank bodies, knee joint mechanisms, ankle joint mechanisms, bandages and soles, the waist mechanism comprises a back plate, a left waistband, a right waistband, limiting strips, triggers, a gear and racks, the limiting strips are recessed into rectangular grooves of the left waistband and the right waistband and fixed by bolts, the left waistband and the right waistband are inserted into sliding ways on two sides of the back plate, the front ends of the left waistband and the right waistband are connected with the racks, the gear is mounted on a rotating shaft of the middle of the back plate and meshed with the racks, the triggers are mounted on two sides of the back plate, so that the limiting strips are clamped, and each hip joint mechanism comprises a left connector, a right connector, a hip joint body, a harmonic reducer, a bolt, a disk-type motor, a thigh telescopic rod and a motor support. The mechanical device has the advantages that a whole mechanism is compact in design, space utilization rate is high, the shortcomings of overlarge exoskeleton size and clumsy action caused by a directly-connected mode of a traditional motor are overcome, a structure of a synchronous belt cannot be lubricated, transmission is reliable and stable, and maintenance cost is low.

Description

technical field [0001] The invention relates to a wearable walking aid exoskeleton for rehabilitation of lower limbs, belonging to the field of medical rehabilitation equipment. It is suitable for sports rehabilitation training for patients with lower limb paralysis. Background technique [0002] With the development of society, due to brain diseases, traffic accidents, sports injuries and other factors, patients with paralysis of the lower limbs have gradually received social attention, and their demand for rehabilitation and walking aids is becoming more and more urgent. Exoskeleton robots can replace the heavy manual work of doctors. training work. The lower extremity rehabilitation training mechanical device has developed rapidly under this condition as a mechanical device for treating and solving daily activities. However, the currently developed lower extremity exoskeleton has complex drives, large volume, and low space utilization, resulting in a large overall shape...
