WIPO Patent Application WO/2024/045253

A1

The present invention relates to a cardan universal joint foot mechanism of a foot-type walking robot. The mechanism is mainly composed of an Achilles tendon upper support, an Achilles tendon damper, a cardan universal joint assembly, a foot support base, limiting rubber, a foot connecting disc, a sole pad assembly, a limiting self-lubricating bearing, a foot connecting support assembly, and a wrist buffer. The present invention is integrated with bionics design ideas, is divided into four major parts: an ankle joint, a sole, an Achilles tendon and a wrist, and is suitable for a foot-type walking robot in complex road conditions. The design takes simplicity and reliability as principles to ensure the passing capacity and service life of a robot. The Achilles tendon damper, the wrist buffer, a cardan shaft joint, a leaf spring steel elastic skeleton, a hollow sole rubber pad, and other structures are highly innovative, and satisfy the functional requirements of foot buffering, swinging, rotation, slip prevention, etc. of a foot-type walking robot.
