Abstract

The invention belongs to the technical field of rehabilitation therapy instruments, and particularly relates to a damper and a walking aid robot. The damper is characterized in that a hydraulic rod stretches into a hydraulic cylinder from the tail end of the hydraulic cylinder; a seal ring connected with an inner surface of the hydraulic cylinder is arranged on the inner end of the hydraulic rod;a free piston and a first compression spring are arranged between the seal ring and a fixed end of the hydraulic cylinder; two ends of the first compression spring press against the free piston and the fixed end; the free piston and the seal ring jointly divide a space in the hydraulic cylinder into a first cavity, a second cavity and a third cavity; liquids are arranged in the second cavity and the third cavity; a first through hole communicating with the second cavity and the third cavity is formed in the seal ring; and a flow adjusting device for controlling the flow velocity of the liquidpassing through the first through hole is arranged on the hydraulic rod. The damper provided by the invention has adjustable damping, provides a larger support force, and can mutually transform gravitational potential energy of a body and elastic potential energy of the first spring. The damper provided by the invention has the characteristics of small energy consumption and simple structure.

Description

technical field [0001] The invention belongs to the technical field of rehabilitation medical equipment, and in particular relates to a damper and a walking assistant robot. Background technique [0002] Walking-assisting robots are mainly divided into military and civilian use. Civilian walking-assisting robots are mainly used for disability assistance, rehabilitation and medical treatment. Walking-assisting robots provide protection and walking power for the wearer. Usually, the walking-assisting robot assists the lower limbs, and the driving of the knee joint is particularly important. In the prior art, the knee joint is mostly driven by motor or hydraulic pressure. When using hydraulic drive, a hydraulic pump is required as the power source. The hydraulic pump is complex in structure, heavy in weight, and consumes a lot of energy during operation. Therefore, the existing technology The actuators of walking aid robots have complex structures and high energy consumption. ...
