Lower limb assistance mechanical outer skeleton

Abstract

The invention discloses a lower limb assistance mechanical outer skeleton. The lower limb assistance mechanical outer skeleton comprises a back support, a thigh part, a shank part, a knee joint driving mechanism and a foot sole. The top of the thigh part is hinged to the back support through a hip joint. The top of the shank part is hinged to the bottom of the thigh part through a knee joint. The knee joint driving mechanism drives the knee joint to move, and thus the shank part rotates relative to the thigh part through the knee joint. The foot sole is connected with the bottom of the shank part through an ankle joint. The lower limb assistance mechanical outer skeleton can enhance the high load and flexible movement ability of people and has the characteristics of being low in cost, convenient to use and simple to maintain.

Description

technical field [0001] The invention relates to a lower limb assist mechanical exoskeleton. Background technique [0002] At present, in order to reduce human labor intensity and improve work efficiency, mechanization has become a necessary means. However, some existing mechanized equipment is limited by some external conditions and cannot effectively solve the problem of high-height and heavy-duty exercise. Existing exoskeleton technologies mostly use hydraulic drive. Expensive, not easy to popularize and use. In the structure disclosed in the Chinese patent with the application number 201511019542.4, the driving method of the spring energy storage bouncing exoskeleton is that the motor drives the rope through the screw nut pair, and the other end of the rope is connected to the spring hook pressing part of the leg, so that the spring compresses and stores energy. After reaching a certain level, the elastic potential energy is triggered by the return poke rod to achieve th...

[0002] At present, in order to reduce human labor intensity and improve work efficiency, mechanization has become a necessary means.

Existing exoskeleton technologies mostly use hydraulic drive. Expensive, not easy to promote and use

In the structure disclosed in the Chinese patent with the application number 201511019542.4, the driving method of the spring energy storage bouncing exoskeleton is that the motor drives the rope through the screw nut pair, and the other end of the rope is connected to the spring hook pressing part of the leg, so that the spring compresses and stores energy. After reaching a certain level, the elastic potential energy is triggered by the return poke rod to achieve the power-assisted effect. The transmission of this design is too complicated and the efficiency is low. When the human body is walking, the stability of the lower limbs is poor, causing certain limitations.
