Title:
BIONIC FOOT WALKING AID WITH DRIVE CONTROL
Document Type and Number:
WIPO Patent Application WO/2017/117886
Kind Code:
A1
Abstract:
A bionic foot walking aid with drive control, comprising: a main support frame (1), a controller unit (2), a left supporting leg assembly (3), a right supporting leg assembly (4), a left leg motion driver (5) for driving the left supporting leg assembly (3), and a right leg motion driver (6) for driving the right supporting leg assembly (4). The left supporting leg assembly (3) and the right supporting leg assembly (4) each comprises a first supporting leg (7) and a second supporting leg (8), wherein the leg performs a front-rear alternating motion. The left leg motion driver (5) and the right leg motion driver (6) each comprises a power device (10) controlled by the controller unit and affixed within a casing (9) on the main support frame. The first supporting leg (7) and the second supporting leg (8) of the supporting leg assembly perform the front-rear alternating motion under control of the controller unit (2) and the leg motion drivers (5, 6), realizing forward movement simulating the bipedal front-rear alternating motion of a human. The walking aid can move forward independently, and has improved abilities for stepping over obstacles and traversing stairs. The walking aid is more comfortable and requires less energy to use, has good stability at rest and offers better user safety.
