Abstract

The invention discloses a ratchet-bevel gear drive knee joint negative work capturing lower extremity exoskeleton, comprising a thigh support plate, a calf support rod, a gear train carrying platform and a knee joint gear mechanism. One end of the gear train carrying platform is fixed to the thigh support plate The other end is connected with the knee joint gear mechanism through the first axial rotating member, and the end of the knee joint gear mechanism away from its connecting gear train carrying platform is connected with the calf support rod, and the first axial rotating member is also provided with The coil spring, the inner end point of the coil spring is fixedly connected to the first axial rotating member, and the outer end point of the coil spring is used for being fixedly connected with the wheel train carrying platform, so that the coil spring can be compressed when the knee is extended, and can be compressed when the knee is bent. Reset during exercise. The solution can effectively absorb the negative work during the knee extension process of the knee joint, thereby reducing the impact of the negative work on the knee joint, and effectively protecting the knee joint.

Description

technical field [0001] The invention relates to the technical field of wearable devices, in particular to a ratchet-bevel gear transmission knee joint negative power capture lower limb exoskeleton. Background technique [0002] An exoskeleton is a structure that can be worn on the human body. It can closely link the behavior of the human body with the kinetic energy of the mechanical system. At the same time, it can provide the additional power needed by the human body, thereby enhancing the human motor function. The different parts are divided into upper extremity exoskeleton and lower extremity exoskeleton. The upper extremity exoskeleton is worn on the upper extremity of the human body and mainly provides assistance for the transportation of the upper extremity of the human body. [0003] Lower limb exoskeletons can be divided into knee joint exoskeletons, ankle joint exoskeletons, etc. according to different wearing parts. The knee joint exoskeletons in the prior art are...
