Auxiliary walking device based on hybrid drive of worm gear reducer motor and energy storage spring

Abstract

The invention provides an auxiliary walking device based on a hybrid drive of a worm and gear reducer motor and an energy storage spring, including a waist belt, and protective shells are arranged on both sides of the waist belt, and the protective shell is composed of a protective shell C and a protective shell A. There is a driving wheel in the protective shell, an internal tooth ratchet is arranged on the inner side of the driving wheel, a driven wheel is installed in the internal tooth ratchet, an electromagnet is arranged at the upper end of the driven wheel, a permanent magnet B is arranged at the lower end of the electromagnet, and a permanent magnet B is arranged at the upper end of the driven wheel. A pawl is installed, a pressing block is provided at the rear end of the pawl, a permanent magnet A is provided at the rear end of the pressing block, a thigh rod fixing part is installed on the inner side of the driven wheel, a guide rail is arranged on the inner side of the thigh rod fixing part, and a thigh is connected to the lower end A booster rod, an energy storage spring is installed on the guide rail, and an adjustment rod is connected to the inner side of the protective case C. The invention solves the long-term walking obstacle problem of the elderly group, and has the advantages of automatically adapting the step distance to people's walking habits in different situations, adjustable assist mode, safety and reliability, simple structure and low cost.

Description

technical field [0001] The invention relates to the technical field of walking assist devices, in particular to an auxiliary walking device based on a hybrid drive of a worm gear motor and an energy storage spring. Background technique [0002] After more than 40 years of rapid development of reform and opening up, my country has entered an era of high life expectancy and aging. The problem of aging has aroused widespread concern in the whole society. The main problem caused by population aging is the sharp increase in the population of disabled elderly. , according to relevant forecast analysis, by 2050, the number of elderly people who have difficulties in doing housework will reach 140 million, and 21.1% will have moderate difficulty in walking. Insufficient lower limb strength is the main reason why the elderly cannot walk for a long time, leading to the The range of people's life is limited, and the use of auxiliary walking devices is an effective way to solve this proble...

AI Technical Summary

Problems solved by technology

The unpowered walker has the following problems: (1) The spring part of the device still needs the human legs to do work and store energy, which does not fundamentally solve the problem of "tiredness" of the elderly walking for a long time (2) When standing still, the legs are still affected Forward force, poor comfort (3) single booster mode

But at the same time, there are also the following problems: (1) Pre-adaptive training is required for each walking mode; (2) The structure is relatively complex, and the reliability needs to be improved; (3) Most of them fail to consider safety from the structure, such as failure Sudden stop, etc. (4) The cost is too high and it is difficult to popularize (for example, the price of ATOUN lightweight waist exoskeleton "ATOUNMODEL Y" planned to be mass-produced by a Japanese exoskeleton manufacturing company is as high as 35,000 RMB)
