Abstract

A rehabilitation training device for lower limb exoskeleton joints comprises a control mechanism, a driving motor, a transmission assembly, a limiting assembly, a knee joint inner fixing plate, a knee joint outer fixing plate and a thigh bone straight plate. The transmission assembly comprises three bevel gears, a thrust ball bearing and a deep groove ball bearing, so that stable transmission of a driving motor is achieved. The limiting assembly comprises limiting grooves formed in the boundaries of the thigh bone straight plate and connecting shafts detachably connected to lug plates. A user can adjust the connecting and mounting positions of the connecting shafts on the lug plates to define the limiting position where the thigh bone straight plate makes circular arc movement through matching of clamping of the connecting shafts and the limiting grooves. The device is simple in overall structure, stable in driving and convenient to use; stability can be well met when the lower limb exoskeleton joints are driven, the limiting adjustment effect is achieved, and safety and convenience are met when the user uses the rehabilitation training device so that the user can be treated effectively and scientifically.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary equipment, in particular to a rehabilitation training device for lower extremity exoskeleton joints. Background technique [0002] At present, medical exoskeleton technology at home and abroad is developing rapidly, and is increasingly entering the stage of practical application. Existing lower limb assist exoskeleton robot equipment is mainly composed of mechanical, sensing and control components. However, in these existing human body exoskeleton devices, most of the driving mechanisms applied to the joints have poor motion stability, so that the user cannot ensure safety during use. In addition, due to the instability of the driving mechanism, the utilization of energy is not high, which reduces the utilization efficiency. [0003] At the same time, the existing human exoskeleton device also has a major defect: the limit mechanism applied to the joints has a complex structure when re...
