Embodiment Construction

[0053] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0054] as attached figure 1 to attach image 3As shown, a ratchet-bevel gear transmission knee joint negative work captures the lower extremity exoskeleton, including a thigh support plate 1, a calf support rod 2, a gear train carrying platform 5 and a knee joint gear mechanism 6, and the thigh support plate 1 is provided with a thigh A binding mechanism 3, a calf binding mechanism 4 is provided on the calf support rod 2, one end of the wheel train carrying platform 5 is fixedly connected with the thigh support plate 1, and the wheel train carrying platform 5 is far away from the end connected to the thigh support plate 1 and the knee joint. The gear mechanism 6 is rotationally connected through the first axially rotating member 13 to adapt to the knee flexion and knee extension movements of the human knee joint. A coil spring 14 is also provided on ...

Abstract

The invention discloses a ratchet wheel-bevel gear transmission knee joint negative work capturing lower limb exoskeleton. The exoskeleton comprises a thigh supporting plate, a shank supporting rod, a gear train carrying platform and a knee joint gear mechanism, one end of the gear train carrying platform is fixedly connected with the thigh supporting plate, and the other end of the gear train carrying platform is rotationally connected with the knee joint gear mechanism through a first axial rotating piece; and the end, away from the connected gear train carrying platform, of the knee joint gear mechanism is connected with the shank supporting rod, a coil spring is further arranged on the first axial rotating piece, the inner end point of the coil spring is fixedly connected to the first axial rotating piece, and the outer end point of the coil spring is used for being fixedly connected with the gear train carrying platform so that the coil spring can be compressed during knee stretching movement, and resetting is realized during knee bending movement. According to the scheme, negative work in the knee joint stretching process can be effectively absorbed, then impact of the negative work on a knee joint is relieved, and the knee joint is effectively protected.

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 work capture lower extremity 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. The different parts are divided into upper limb exoskeleton and lower limb exoskeleton. The upper limb exoskeleton is worn on the upper limb of the human body and mainly provides assistance for the transportation of the upper limb of the human body. The lower limb exoskeleton is worn on the lower limb of the human body and mainly provides assistance for the movement of the lower limb of the human body. [0003] The lower extremity exoskeleton can be divided into knee exoskeleton, ankle exoskeleton, etc. according to different wearing parts. The knee exoskeleton in the prior art is ma...
