Embodiment Construction

[0056] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0057] as attached figure 1 to attach image 3 As shown, the knee joint negative work capture exoskeleton device includes a thigh connector 1 and a calf connector 2. The thigh connector 1 is provided with a thigh binding mechanism 6, and the calf connector 2 is provided with a calf binding mechanism 7. Thigh connecting part 1 is provided with thigh connecting part 20 near one end of calf connecting part 2, and calf connecting part 18 is provided at one end of calf connecting part 2 close to thigh connecting part 1, and calf connecting part 18 is also provided along the axial direction. Rotate the connecting shaft 19, the thigh connecting portion 20 and the shank connecting portion 18 are connected in rotation through the rotating connecting shaft 19, to adapt to the knee flexion and knee extension motion of the human knee joint, a coil spring 21 is al...

Abstract

The invention discloses a knee joint negative work capturing exoskeleton device. The knee joint negative work capturing exoskeleton device comprises a thigh connecting piece and a shank connecting piece; a thigh binding mechanism is arranged on the thigh connecting piece; a shank binding mechanism is arranged on the shank connecting piece; a thigh connecting part is arranged on the thigh connecting piece; a shank connecting part is arranged on the shank connecting piece; a rotating connecting shaft is further arranged on the shank connecting part in the axial direction; the thigh connecting part and the shank connecting part are rotationally connected through the rotating connecting shaft; a coil spring is further arranged on the rotating connecting shaft; the inner end point of the coil spring is fixedly connected to the rotating connecting shaft; and the outer end point of the coil spring is fixedly connected to the thigh connecting part, and therefore, the coil spring is compressed to absorb negative work during knee stretching, and the coil spring resets to provide assistance for knee bending during knee bending. According to the invention, the negative work in the knee joint stretching process can be effectively absorbed, and therefore the impact of the negative work on the 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 an exoskeleton device for capturing knee joint negative work. 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 mainly used to provide assistance to...
