Description
Technical field
The utility model relates to a kind of wheelchair, specially a kind of old walk-aid equipment.
Background technique
It is shown according to Office of the National Committee on Aging research report, China comes into ageing stage at present, and China is flat in this stage
5,960,000 elderly population will be increased newly every year, arrive the year two thousand twenty, elderly population are up to 2.5 hundred million, and various disease of old people patient numbers are year by year
Increase, nursing resource becomes relative scarcity.Along with being continuously increased for aging populations, most significant feature is exactly the elderly
It has defective vision, physical decline, muscle is powerless, and inconvenient walking has seriously affected the daily life quality of the elderly.It is simple in the market
Walk helper function it is too simple and safety is insufficient, and high-end intelligent assistant robot is since price is prohibitively expensive, and
It cannot be received by most of old men.For the daily walking back-up needs for supporting, improving the elderly, it is intended to develop a function compared with
The secondary row travelling wheels chair that perfect, safe, light, reasonable price can be received by common the elderly.
Summary of the invention
The utility model mainly for insufficient present on the prior art, towards physical decline, muscle is powerless, and walking is not
Just the elderly provides a kind of old walk-aid equipment easy to use, multiple functional, and daily suitable for the elderly goes out
It takes exercise.Three kinds of implementation, electronic walk help and electric wheelchair functions are realized by simple structure.
In order to achieve the above object, the solution of the utility model is as follows:
The utility model proposes to improve on the basis of electric wheelchair, to existing electric wheelchair, except pushing away for electric wheelchair
Outside capable and electric wheelchair mode, electronic walk help mode is proposed, it may be assumed that user stands on inside electronic walk helper, walk helper
