Auxiliary walking device based on combination driving of worm and gear speed reducing motor and energy storing spring

Abstract

The invention provides an auxiliary walking device based on combination driving of a worm and gear speed reducing motor and an energy storing spring. The auxiliary walking device comprises a waistband, wherein protecting housings are arranged on two sides of the waistband, and each protecting housing consists of protecting housings A and a protecting housing C; a driving wheel is arranged in eachprotecting housing, and an internal tooth ratchet wheel is arranged on the inner side of each driving wheel; a driven wheel is mounted in each internal tooth ratchet wheel; an electromagnet is arranged at the upper end of each driven wheel; a permanent magnet B is arranged at the lower end of each electromagnet; a pawl is mounted at the upper end of each driven wheel, and a pressing block is arranged at the rear end of each pawl; a permanent magnet A is arranged at the rear end of each pressing block; a thigh rod fixing piece is mounted on the inner side of each driven wheel; a guiding wheel is arranged on the inner side of each thigh rod fixing piece; a thigh assisting rod is connected to the lower end; and an energy storing spring is mounted on each guiding rail, and an adjusting rod isconnected to the inner side of the protecting housing C. The problem of long-time gait disturbance of elder people is solved, and the auxiliary walking device has the advantages that step pitches canautomatically adapt to walking habits of people under different conditions, assistance mode is adjustable, and the auxiliary walking device is safe, reliable, simple in structure and low in 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)
