The invention relates to a parallel type
ankle rehabilitation training apparatus. The parallel type
ankle rehabilitation training apparatus comprises a
thigh support base, a
thigh support base internal rod, a
thigh support base external rod, a shank connection sleeve, a sole support plate, a base plate, a first retractable moving
branch chain, a second retractable moving
branch chain, a fixed lifting lug, a sole support plate lifting lug and a
rope, wherein static frames of the first and second moving
branch chains are fixedly connected with the base plate; retractable ends of both the first and second moving branch chains are connected with the sole support plate by spherical hinges; and the fixed lifting lug and the sole support plate lifting lug are connected by the
rope. By adopting a 2-PSS / S type parallel mechanism, two
rotational degrees of freedom can be realized, and as an
ankle is the rotation center of the apparatus, movements such as back extension or
plantar flexion, and introversion or extroversion of the ankle can be really done. The parallel type
ankle rehabilitation training apparatus has a high-rigidity structure and high
bearing capacity, and can effectively reduce the burden of a damaged ankle; main movements of the ankle can be really simulated by using a simple structure, so that the bio-imitability is high; and a driving link is static, and the dynamic property is high.
