Crawler-type all-terrain electric chair

Abstract

The invention discloses a crawler-type all-terrain electric chair, which comprises a crawler chassis, crawlers and a seat; the seat is installed on the crawler chassis, the left side and the right side of the crawler chassis are of trapezoidal framework structures, the advancing ends of the trapezoidal framework structures are bevel edges, the retreating ends of the trapezoidal framework structures are straight edges, the four corners of each trapezoidal framework structure are chamfered into circular arcs, and the crawlers are installed on the trapezoidal framework structures on the two sides of the crawler chassis. The crawlers are adopted for driving, and the crawlers are long, wide and large in grounding area, so that the crawlers can stably run on potholes, low, soft, soil, ice and snow grounds. The advancing ends and the retreating ends of the crawlers are both in a large arc shape, and the seat can be driven to easily cross a roadblock with a length of 15cm or below no matter the crawlers advance or retreat; and the grounding straight part of the crawlers is long enough, so that the electric chair can be operated to go backward to climb stairs and steps or go forward to go downstairs and stairs.

Description

technical field [0001] The invention relates to the technical field of electric chairs, in particular to a crawler-type all-terrain electric chair. Background technique [0002] For the elderly or disabled people who cannot walk independently, the current means of transportation for short trips are classic four-wheel electric wheelchairs or four-wheel wheelchairs. But the problem is that the diameters of the left and right front wheels of these two kinds of transportation tools are relatively small, and the passability of the ground is poor. The current reality of our country is: many towns with underdeveloped economy do not have perfect slow traffic lanes or sidewalks. Even if there are, some road sections have poor road quality due to various reasons; , Some areas will be covered by ice and snow for as long as half a year. To sum up, whether it is a four-wheel electric wheelchair or a four-wheel push wheelchair, the travel range of the elderly and the disabled will be li...

Problems solved by technology

But the problem is that the diameters of the left and right front wheels of these two means of transportation are relatively small, and the passability of the ground is poor.

The current reality of our country is: many towns with underdeveloped economy do not have perfect slow traffic lanes or sidewalks. Even if there are, some road sections have poor road quality due to various reasons; , some areas will be covered by ice and snow for as long as half a year

To sum up, whether it is a four-wheel electric wheelchair or a four-wheel push wheelchair, the travel range of the elderly and the disabled will be limited due to the ground or climate.

[0003] In addition to the above-mentioned ground and climate factors, elevators were rarely installed in the multi-storey houses built in the early years of my country's cities and towns; Difficulty walking on indoor or outdoor steps

In recent years, some manufacturers have installed electric crawlers on the back of the wheelchair or on the bottom of the chair surface. Although it has solved the problem of assisting people to go up and down stairs or steps to a certain extent, it needs to rely on strong escorts to pull hard and perform complicated operations. Safe and smooth process can be guaranteed
