Foot rehabilitation device with adjustable oscillation amplitude and adjustment method thereof

Abstract

The invention relates to a foot rehabilitation device with adjustable oscillation amplitude and an adjustment method thereof. The device comprises a rack and a rehabilitation massage component, the rehabilitation massage component comprises a middle shaft, an upper mounting plate and two rotation shafts, and a gear A, a gear B, a friction plate and a gear C are arranged on the middle shaft; shifting forks which toggle the friction plate to move up and down are arranged on the rack, the rotation shafts sleeve the gear D and an integrated gear group, and the gear D is meshed with the gear A in atransmission mode; the integrated gear group comprises an annular base body, a gear E, a gear F and a gear G are arranged on the periphery of the annular base body, and an eccentric spherical-hinge base is arranged in the gear D; a gear H which is meshed with a gear E in a transmission mode is arranged on the lower side of the gear D, the gear H is connected with the eccentric spherical-hinge base in a rigidity mode, and a motor is arranged on the upper mounting plate; the motor is connected with the middle shaft through a shaft coupling, massage base bodies are arranged on two sides of the motor, the lower ends of the massage bodies are connected with cross-shaped universal shaft couplings, and the cross-shaped universal shaft couplings are connected with the eccentric spherical-hinge base through rockers. According to the foot rehabilitation device, ankle rehabilitation is combined with foot sole massage, and the oscillation amplitude can be adjusted.

Description

Technical field [0001] The invention relates to a foot rehabilitation device with adjustable swing amplitude and an adjustment method thereof. Background technique [0002] The foot is one of the most important limbs that support the human body in daily activities, and the movement of the foot is dominated by the ankle joint, so the ankle joint and the foot are closely related. However, due to long-term weight-bearing and over-activity, or the decline in physical function of the elderly, some of the functions of the feet are lost, which affects people's daily life, so foot rehabilitation devices are particularly important. At present, most foot rehabilitation devices have the following problems: there are many redundant degrees of freedom, the overall mechanism is too complicated, and the operation is inconvenient; the degrees of freedom are insufficient to carry out effective active and passive training; the stiffness of the parallel mechanism is insufficient, and the series mec...

Problems solved by technology

However, due to long-term weight-bearing and excessive activities, or the decline in physical function of the elderly, part of the function of the foot is lost, which affects people's daily life, so foot rehabilitation devices are particularly important.

At present, most of the foot rehabilitation devices have the following problems: many redundant degrees of freedom, the overall mechanism is too complicated, and the operation is inconvenient; the degree of freedom is insufficient, and effective active and passive training cannot be performed; the parallel mechanism is not rigid enough, and the series mechanism is difficult to carry the weight of the human body; The driving efficiency is low, and precise control cannot be achieved. At the same time, the existing foot rehabilitation device can realize the swing adjustment of the massage seat when the ankle rehabilitation and foot massage are combined.
