Three-degree-of-freedom ankle active and passive training device

The utility model relates to a three-degree-of-freedom ankle active and passive training device. The device comprises a bottom frame, an ankle supporting mechanism, a slide rail mechanism, a connecting mechanism and a driving mechanism, wherein the ankle supporting mechanism is used for placing a sole; the ankle supporting mechanism is connected with the slide rail mechanism through the connecting mechanism; the ankle supporting mechanism and the slide rail mechanism are fixedly arranged on the bottom frame. According to the three-degree-of-freedom ankle active and passive training device, the ankle supporting mechanism and the slide rail mechanism are connecting by applying the telescopic connecting mechanism to realize three-degree-of-freedom spatial training of an ankle, so three-degree-of-freedom rehabilitation training of dorsiflexion/plantar flexion, introversion/extroversion and pronation/external rotation of the human ankle can be realized; the device has the advantages of simple integral structure, easiness in production and manufacturing and convenience in maintenance.
