Wearable pneumatic skiing exoskeleton power assisting device

Abstract

The invention discloses a wearable pneumatic skiing exoskeleton power assisting device which comprises a thigh assembly, a crus assembly and a control device, wherein the lower end of the thigh assembly is connected with the crus assembly through a rotating assembly and an air spring bumper, and a thigh fixing pad is arranged at the upper end of the thigh assembly. By means of joint action of telescopic movement of an air spring and a variable damper, shock effects in skiing to knee joints are reduced, auxiliary force is provided for the knee joints, the gravity is compensated, and muscle fatigue in exercise is avoided; by means of designing and utilizing an embedded control system based on an ARM board and a PC, human-computer interaction and real-time control on a robot are better achieved; in addition, human motion parameters obtained through a gyroscope and an accelerometer can be used for detecting intention of a user; furthermore, the air spring and textile are utilized for automatically adjusting auxiliary torsion at the knee parts. The wearable pneumatic skiing exoskeleton power assisting device disclosed by the invention can be well applied to a wearable skiing exoskeletonrobot, can reduce energy consumption in skiing, improves comfortableness and has great application value.

Description

technical field [0001] The invention relates to a lower limb exoskeleton robot, in particular to a wearable pneumatic skiing exoskeleton assisting device. Background technique [0002] Skiing is a fun sport that can enhance cardiopulmonary function, improve nervous system conditions, and strengthen the body. Since the human knee joint needs to be bent for a long time and maintain a certain angle during the skiing process, and a lot of physical strength will be consumed during skiing, so long-term skiing will cause problems such as muscle fatigue and knee joint pain. However, the current power-assisted walking devices are mostly used to assist people who have difficulty walking on flat ground, and cannot be used for high-speed snow skiing. At present, there is no device that can reasonably solve these problems. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a wearable pneumatic ski exoskeleton power assist device. [0004] The purpos...
