Abstract

The invention discloses a rehabilitation device combined with a swing-rod-type cam and a multi-stage wheel train and a working flow of the rehabilitation device. Existing lower-limb rehabilitation mechanical structures are complicated and large in power consumption. The rehabilitation device adopts a mode that a gear mechanism is combined with belt transmission, and a function of fitting complex movement characteristics of the human legs is achieved through an uneven transmission ratio of non-circular gears. The cam is driven by a motor to drive a connecting rod to make reciprocating movement,and the connecting rod drives a thigh shell connected with the connecting rod to move, so that the first-stage non-circular gear is meshed to transmit movement to the second-stage non-circular gear through a first-stage belt pulley, then the movement is transmitted to a circular gear through a second-stage belt pulley, and therefore the movement of a whole pedal part is completed. The rehabilitation device is used for leg rehabilitation training of patients with leg fractures, complicated exercise rehabilitation tracks can be completed by adopting one low-power motor, and the structure is simple.

Description

technical field [0001] The invention belongs to the field of medical rehabilitation machinery, and in particular relates to a rehabilitation device combined with a swing-rod cam and a multi-stage gear train and its working process. Background technique [0002] In recent years, my country, like many developed countries in the world, is entering an aging process, and due to the problem of China's population, the aging process is accelerating. With the gradual increase of the aging population, the proportion of the disease is also increasing. At the same time, due to the diversification of the types of vehicles and the increase in the number, the number of limb injuries caused by traffic accidents is also increasing. Mechanical rehabilitation of the lower extremity after fractures is increasingly important. [0003] The patent with the publication number N204798293U discloses a double eccentric wheel type lower limb rehabilitation machine. The mechanism is mainly composed of...
