A free-moving adaptive weight-reducing trolley for lower limb rehabilitation training

Abstract

The invention relates to a free-moving adaptive weight-reducing trolley for lower limb rehabilitation training, which includes a trolley frame, a hub motor, a universal wheel, a universal wheel connecting plate, an adaptive adjustment mechanism, an active adjustment mechanism, and a four-way pressure Sensor motion intention monitoring mechanism, connection adjustment mechanism, control circuit board and power battery box; the hub motor is installed on the rear of the trolley frame through the self-adaptive adjustment mechanism; the universal wheel is installed on the The bottom of the front side of the trolley frame; an active adjustment mechanism is installed on the trolley frame, and the four-way pressure sensor motion intention monitoring mechanism is installed on the active adjustment mechanism through a slide table, and the connection adjustment mechanism is fixed On the motion intention monitoring mechanism of the four-way pressure sensor. The weight loss of the patient is achieved through the adaptive support structure, so that the patient can keep the foot in contact with the ground all the time during walking, and follow the patient to move freely, improving the effect of rehabilitation training.

Description

technical field [0001] The invention relates to the field of rehabilitation training equipment, in particular to a free-moving self-adaptive weight-reducing trolley for lower limb rehabilitation training. Background technique [0002] Clinically, rehabilitation training for lower limb motor dysfunction such as hemiplegia and high paraplegia caused by cerebral palsy, stroke, and brain injury usually requires the use of weight loss devices to support the patient's weight and assist them in completing gait training. The application of lower extremity exoskeleton robots in gait rehabilitation training can effectively promote the recovery of patients, but the weight of the mechanism itself is relatively large. During the early rehabilitation training of patients, it is also necessary to use a weight reduction mechanism to offset or partially offset the weight of the exoskeleton robot and the patient itself. weight. [0003] At present, in rehabilitation training, the method of f...

Problems solved by technology

However, for children with cerebral palsy who need long-term gait rehabilitation training, they have obvious resistance and fear of persisting in training in a single, fixed environment
