Wearable lower limb power-assisted mechanism

Abstract

The invention provides a wearable lower limb power-assisted mechanism; a left side waist support and a right side waist support are identical and in an L-shaped structure; one ends of the waist supports are fixedly connected on two sides of a waist adjusting mechanism through a connecting flange; the side faces are tightly connected with two backside support plates through screws; the two backside support plates are vertical to the waist supports; two up-down parallel support connecting rods are screwed on the backside support plates; a control box is suspended on the support connecting rods through buckles; a waist belt penetrates trepanning in middle of the backside support plates; a hip joint driving mechanism is located below the waist supports, and screwed with connecting shafts of the other ends of left and right side waist supports; a first Femur connecting rod, a second femur connecting rod, a first femur band and a second femur band form a hip joint execution mechanism; a knee joint driving mechanism is tightly connected on the second femur connecting rod; a first shank connecting rod, a second shank connecting rod, a first shank band and a second shank band form a knee joint execution mechanism.

Description

technical field [0001] The invention relates to a lower limb assisting device, in particular to a wearable lower limb assisting mechanism. Background technique [0002] As an important joint of the lower limbs of the human body, the hip joint supports the weight of the entire trunk, and it bears much greater physiological pressure than other joints; the knee joint is the largest and most complex joint in the human body. hub, so its incidence rate ranks first among all joints. Their health directly affects people's daily activities, such as walking, running, jumping, etc. Because of this, the joints of the lower limbs of the human body are under high load in daily life, and excessive fatigue or even damage to the joints will bring about various Such lesions, the joint torque of the lower limb joints of the elderly is not enough to meet the needs of normal movement with the growth of age and the decline of muscle strength. External torque to make up for the lack of output to...

AI Technical Summary

Problems solved by technology

[0003] Lower limb joint assist mechanisms are mainly driven by motors, hydraulic drives or pneumatic drives. At present, many joint assist mechanisms use hydraulic or pneumatic drive methods. However, hydraulic or pneumatic drive methods have disadvantages such as large noise, more pollution, short strokes, and low control accuracy. The lower extremity joint power-assisted mechanism has a complex structure, bulky size, troublesome wearing, and poor coupling performance with the human body. In addition, most of the existing power-assisted exoskeletons on the market are complex in design and expensive, so there is an urgent need for a simple structure, convenient control, and comfortable wear. A lower limb assisting mechanism that meets the level of mass consumption
