Description

Intelligent walking aid

Technical Field

The invention relates to a walking aid, in particular to an intelligent walking aid capable of automatically ascending and descending stairs.

Background

In life, the common problems of the old are that legs and feet are inconvenient, walking is unstable, the old easily falls down, and going up and down stairs are difficult, and people who are old and disabled can speak out to walk out to become a difficult thing.

The walking aids on the market are various, but the walking aids have a plurality of places which are inconvenient to use, most of the walking aids have no auxiliary wheels, the user needs to manually move the walking aids to consume the physical power of the walking aids, the old who is inconvenient to move increases the burden to a certain extent, and the walking aids are added with the auxiliary wheels, so that the burden of the old who walks on a flat road is reduced, but the problem of going upstairs and downstairs is not solved. Aiming at the problems, in order to assist the old and the disabled to normally go out for walking and go upstairs and downstairs, the invention provides the intelligent walking aid which can autonomously control the start and stop of the intelligent walking aid and automatically open and close the upstairs and downstairs, thereby realizing free movement on a level road and automatic upstairs and downstairs, and spanning a certain hollow road section.

Disclosure of Invention

In order to solve the problems, the intelligent walking aid can freely move on a flat road, can automatically go up and down stairs, can span a certain hollow road section, helps the old with inconvenient movement to normally walk on the flat ground and the stairs, and prevents the old from falling down.

The invention provides an intelligent walking aid, which comprises a frame, a start button, a stop button, an upstairs and downstairs button, a planet front wheel, a motor, a telescopic rod, a universal wheel and a storage battery, wherein the start button is arranged on the frame; the start button, the frame upper end is located to stop button and upstairs or downstairs button, the effect of start button and stop button is that manual control intelligence helps capable ware to start and stop, the effect of upstairs or downstairs button is that manual control upstairs or downstairs mode starts and stops, the frame front end is located to the planet front wheel, the planet front wheel is actuating mechanism, frame lower extreme and fixed connection are located to the motor, the frame rear end is located to the telescopic link, the telescopic link can be according to step height flexible, the telescopic link lower extreme is equipped with the universal wheel, frame front end and fixed connection are located to the battery, the battery supplies power for the.

The planet front wheel comprises a stepping motor, a planet carrier, a threaded shaft, an inner gear sleeve, a central wheel, a driving planet gear, a driven planet gear and a tire, wherein the stepping motor is fixedly connected with the planet carrier, a main shaft of the stepping motor is fixedly connected with the threaded shaft, a storage battery supplies power to the stepping motor, the threaded shaft is matched with the inner gear sleeve, an outer ring of the inner gear sleeve is fixedly connected with an inner ring of a bearing, the outer ring of the bearing is fixedly connected with the central wheel, the threaded shaft is driven by the stepping motor to control the central wheel to move axially to be separated from the driving planet gear and the driven planet gear, so that the planet front wheel does linear motion, the function of moving on a flat road is realized, the central wheel is driven by the stepping motor to control the threaded shaft to move axially to be engaged with the driving planet gear and the driven planet gear, the driven planet gear does circular motion by taking the driving planet gear as a, the motor main shaft is connected with the planet carrier, the motor main shaft is fixedly connected with the driving planetary gear, the driven planetary gear is connected with the planet carrier, and the driving planetary gear and the driven planetary gear are fixedly connected with corresponding tires.

Compared with the prior art, the invention has the following advantages:

the intelligent walking aid can automatically set the step distance of the intelligent walking aid in each operation and can automatically control the start and stop of the intelligent walking aid, the planetary front wheel of the intelligent walking aid is an innovative mechanism taking the planetary gear as a driving wheel, and the planetary front wheel can be meshed with or separated from the driving planetary gear and the driven planetary gear by controlling the central wheel to move along the axial direction, so that the planetary front wheel can do horizontal movement and eccentric movement, and the intelligent walking aid can do both horizontal movement and automatic up and down stairs.
