A portable hip assist mechanism

Abstract

The invention provides a portable hip joint assisting mechanism. A left waist support and a right waist support are the same in structure, i.e., both of an L-shaped structure. One ends of the left waist support and the right waist support are fixedly connected to two sides of a waist adjusting mechanism by means of connecting flanges. Two back support plates are fastened and connected to side surfaces of the left waist support and the right waist support by means of screws, and both perpendicular to the waist supports. Two support connecting rods arranged in parallel up and down are in threaded connection with the back support plates. A control box is suspended to the support connecting rods. A waist belt passes through sleeve holes in the middle portions of the back support plates. Hip driving mechanisms are located at lower sides of the waist supports and in threaded connection with the other ends of the left waist support and the right waist support by means of connecting shafts. A joint execution mechanism is formed by a first thigh connecting rod, a second thigh connecting rod, a first thigh binding band and a second thigh binding band. The portable hip joint assisting mechanism provides a motor-driven hip joint assisting mechanism for providing extra torque with the requirements of simple structure, low weight, safety and controllability and high practical and economical values on the mechanism.

Description

technical field [0001] The invention relates to a lower limb assisting device, in particular to a portable hip joint 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 torso. It bears much greater physiological pressure than other joints. Its health directly affects people's daily activities, such as walking, running and jumping, etc., because In this way, the hip joints are under high load in daily life. Excessive fatigue or even damage to the hip joints will cause various lesions. The hip joints of the elderly will decline with age and muscle strength. The torque is not enough to meet the needs of normal movement, and the hip assist mechanism can apply a reasonable external torque to the hip joint of the elderly to make up for the lack of output torque of the elderly and assist their movement. [0003] The hip joint assist mechanism mainly adopts motor drive, hydrau...

AI Technical Summary

Problems solved by technology

[0003] The hip joint assist mechanism mainly adopts motor drive, hydraulic drive or pneumatic drive. At present, many hip joint assist mechanisms adopt hydraulic or pneumatic drive, but the hydraulic or pneumatic drive has the disadvantages of large noise, more pollution, short stroke, and low control accuracy. , making the structure of the hip joint assisting mechanism complex, bulky, troublesome to wear, and poor in coupling performance with the human body. In addition, most of the existing assisting exoskeletons on the market are complex in design and control and expensive, so there is an urgent need for a simple structure, convenient control, wearable A hip assist mechanism that is comfortable and conforms to the level of mass consumption
