Abstract

The invention relates to an adjustable elliptical orbit lower limb rehabilitation wheelchair. The wheelchair comprises a frame, a seat, large wheels and an elliptical orbit implementation device, wherein the elliptical orbit implementation device comprises a fixing seat, a motor, a driven wheel, a belt, central shafts, crank rotating shafts, cranks, limit sliders, connecting rod supports, sliders, a pedal, a walking wheel, a collision bead limit structure and a limit hole. The output shaft of the motor transfers powder to the elliptical orbit driven wheel through the belt, the driven wheel is connected to the fixed seat through the central shaft, one offset crank slider mechanism is arranged on each of two sides of the driven wheel, the cranks on the two sides are connected with the central shaft and rotate with the driven wheel simultaneously, and the cranks on two sides are arranged at an included angle and provided with sliding grooves; one side of each limit slider is matched with the corresponding sliding groove and can slide along the sliding groove, the other end of each limit slider is connected with the corresponding connecting rod support through the crank rotating shaft, one end of each of connecting rod supports on two sides is connected with the corresponding limit slider through the crank rotating shaft, and the other end is connected with the walking wheel.

Description

technical field [0001] The invention relates to the field of rehabilitation medical equipment, in particular to a lower limb rehabilitation wheelchair with an adjustable elliptical trajectory. Background technique [0002] In the process of China's aging process, the disability rate of the elderly is also increasing. Among them, the proportion of people with lower limb walking disabilities has a significant increase trend. In addition, traffic accidents and safety accidents occur frequently, and the number of disabled people is also increasing. Among them, lower extremity disabilities accounted for a large proportion. According to clinical experiments and related theories, for people with motor disabilities, drug therapy and certain surgical treatments can alleviate the patient's condition, but the effect is limited, and the walking ability is still quite different from that before the disease. Repeated rehabilitation exercises can effectively relieve symptoms, promote fun...
