Lower limb exoskeleton robot

Abstract

The invention discloses a lower limb exoskeleton robot. The lower limb exoskeleton robot comprises a crotch support, a left leg support connected to the left side of the crotch support and a right leg support connected to the right side of the crotch support; the left leg support and the right leg support each comprise an angle adjuster and a shank telescopic rod; the upper ends of the angle adjusters are fixedly connected with the corresponding left leg support or the corresponding right leg support, and the lower ends of the angle adjusters are hinged to the upper ends of the corresponding shank telescopic rods; each angle adjuster comprises a shell, a hinge wheel and a locking mechanism, wherein the hinge wheel and the locking mechanism are installed in the shell, the hinge wheel is rotationally connected into the shell, the hinge wheel and the locking mechanism are connected through a traction rope, and the hinge wheel is connected with the upper end of the corresponding shank telescopic rod; and the traction ropes are locked through the locking mechanisms, and then the included angles between the shank telescopic rods and the corresponding angle adjusters are prevented from being reduced. By means of the lower limb exoskeleton robot, the physical power expenditure of a human body in a squatting posture is reduced, meanwhile, a complex circuit structure is avoided, and the fault rate is reduced.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a lower limb exoskeleton robot. Background technique [0002] Exoskeleton robots are not intended to replace manpower, but to combine with people to endow wearers with more capabilities and strength. They are mainly divided into medical scenarios and consumer-grade scenarios. In medical scenarios, it is of great significance to allow people with physical disabilities to stand up. The irreversible injury market is mainly aimed at people with limited mobility caused by muscle, bone, nerve, soft tissue injuries and aging. This group of people is about 25 million; in industrial scenarios, Produce products in the form of individual components such as knees, thighs, arms, etc., with an overall potential market of more than 2.6 million. Consumer-level scenarios, for people or occupations that need to walk and stand for a long time (such as: tour guides, police, outdoor activities and ot...

AI Technical Summary

Problems solved by technology

Consumer-level scenarios, for people or occupations that need to walk and stand for a long time (such as: tour guides, police, outdoor activities and other sub-sectors and application markets), the elderly (aging and health care market), people with disabilities, etc. The market, this part of the market has no fixed parameters, but the space is huge

[0003] For lower extremity exoskeleton robots, there are various structures that have been disclosed, but most of them are complex. The combination of mechanical structures, electronic sensors and controllers makes the cost High, the market sales price is higher, which adds a lot of resistance to the promotion and use

In addition, feedback and control are performed through electronic equipment, and the failure rate is relatively high. Once a failure occurs, the maintenance cost is also high, which leads to high maintenance costs in the later period.
