Abstract

The invention discloses a cam type three-freedom-degree ankle rehabilitative device, relates to ankle rehabilitative devices and aims at solving the technical problems that existing ankle rehabilitation robots are complex in structure, great in parallel connection cooperative control difficulty and poor in ankle rehabilitation training effect. A base of the device is fixedly connected with a first driving motor and a gear I, the gear I is in meshed transmission with a gear II and is fixedly connected with a rotating platform, the rotating platform is fixedly connected with a second driving motor and a gear III, the gear III is in meshed transmission with a gear IV and a inner ring gear, the inner ring gear is connected with a cylindrical cam, the contour face of the cylindrical cam is vertically provided with four cam jacking rods, spherical heads of the rods are hinged to a guide groove of a moving platform, and a shell fixedly connected with a box cover and the rotating platform is arranged at the periphery of the cylindrical cam. The device is used for rehabilitation training of ankles including dorsal flexion / plantar flexion, introversion / extroversion, abduction / adduction and pronation / supination and has the advantages of being simple in control principle, small in drive number and compact in structure.

Description

technical field [0001] The invention relates to an ankle rehabilitation device, in particular to a cam-type three-degree-of-freedom ankle rehabilitation device. Background technique [0002] In daily life and sports, ankle sprains are the most common, among which the ankle ligaments are injured the most. In order to avoid sequelae such as ankle joint dysfunction caused by inadequate treatment, physical therapy is especially needed for auxiliary rehabilitation (such as foot relaxation and massage, etc.), and the damaged ankle joint must be rehabilitated through repeated and step-by-step training. . At present, various types of ankle rehabilitation devices have been applied in the physical therapy of ankle rehabilitation, and there are also patent applications for the prior art of ankle rehabilitation auxiliary devices. [0003] Patent application 201310117264.0 discloses an adjustable ankle rehabilitation device. Although the application uses three linear drivers, it cannot...
