Leg buffer structure of walker

Abstract

The invention discloses a leg buffer structure of a walker, which comprises a toe, a spring, two sets of torque spring pieces, a guide rod, a central leg connecting shaft, a guide rod sleeve, a toe connecting shaft, a first leg connecting shaft, a plurality of leg members and a second leg connecting shaft, wherein the a guide hole is formed in the middle of the toe connecting shaft, one end of the guide rod penetrates through the guide hole and is fixedly connected with the toe, a spring is arranged between the toe and the toe connecting shaft and is sleeved and connected with the guide rod, the other end of the guide rod is partially sleeved to the guide rod sleeve, the guide rod sleeve is connected to the middle of the central leg connecting shaft, the two sets of torque spring pieces are arranged on two sides of the guide hole and are respectively connected with the toe connecting shaft and the first leg connecting shaft, and the leg members are arranged on two sides of the guide rod in a paired crossing manner and are respectively connected with the first leg connecting shaft, the central leg connecting shaft and the second leg connecting shaft. The leg buffer structure has the advantages of realization of multi-directional buffer, simple structure, convenience in operation, wide application range, little abrasion, high flexibility and high stability.

Description

technical field [0001] The invention relates to the field of robots, in particular to a cushioning structure for legs of a walker. Background technique [0002] About 70% of the land on the earth's surface is inaccessible to wheeled transport machines, especially in areas where sudden disasters occur, such as earthquakes, landslides, poisonous gas leaks in factory buildings, etc., and general equipment cannot effectively and quickly detect , Rescue equipment transported to the destination. The legged walker has great dexterity and ground adaptability, and can adapt to transportation work under complex terrain. Therefore, it has important practical significance for the research of military and civilian legged robots. [0003] According to bionic research, animals can greatly save energy consumption and reduce the impact on the body when they touch the ground because their legs have certain elasticity during walking. In engineering practice, walkers often need to transport ...
