Assisted walking device based on ratchet wheel and pawl mechanism and worm wheel and worm speed reduction motor

Abstract

The invention provides an assisted walking device based on a ratchet wheel and pawl mechanism and a worm wheel and worm speed reduction motor. The assisted walking device comprises a waistband, wherein racks are symmetrically arranged on two sides of the waistband, a protecting housing is arranged outside the racks, a worm wheel and worm speed reduction motor is arranged outside the protecting housing, the worm wheel and worm speed reduction motor is connected to a transmission shaft, a driving wheel is mounted in the middle of the transmission shaft, a ratchet wheel A and a ratchet wheel B are separately arranged on the inner and outer sides of the driving wheel, a driven wheel fixing plate A and a driven wheel fixing plate B are separately mounted outside the ratchet wheel A and the ratchet wheel B, a thigh layer board is mounted on the lower part of the driven wheel fixing plate A through a thigh layer board fixing part, a pawl A is rotatably connected to the lower part of the innerside of the driving wheel through a fixing part, a pawl B is rotatably connected to the lower part of the outer side of the driving wheel through a fixing part B, and a thigh fixing tape is arrangedon the inner side of the lower end of the thigh layer board. Compared with the prior art, the assisted walking device solves the problem that it is hard for the elderly to walk for a long time, and has the advantages of walking and stopping anytime, and being adjustable in leg speed, safe and reliable and low in cost.

Description

technical field [0001] The invention relates to the technical field of walking assist devices, in particular to an assist walking device based on a ratchet and pawl mechanism and a worm gear motor. Background technique [0002] my country has entered an era of population aging. According to the "China Population Aging Development Trend Forecast Research Report", my country is in the stage of rapid population aging in the first 20 years of this century, the population aging will accelerate in the middle 30 years, and it will be stable and severe in the second 50 years of this century. In the stage of globalization, population aging will accompany China for a whole century. The muscle strength of the elderly will gradually decrease with age, and the decline in the strength of the lower limbs is most obvious, which affects the mobility and quality of life of the elderly. The use of auxiliary walking devices can solve the problem of weakness in the lower limbs of the elderly to...
