Rapidly-dismounted electric stair-climbing wheelchair

Abstract

The invention discloses a rapidly-dismounted electric stair-climbing wheelchair, belonging to a transportation tool which can continuously travel on the flat ground and continuously climb stairs. The stair-climbing wheelchair comprises a wheelchair frame part capable of adjusting the distance between a front wheel set and a rear wheel seat, a detachable folding wheel chair frame and a seat part, a composite rear wheel set part, a stair-climbing driving part, an anti-forward support part, a seat lifting part and a system power supply part, wherein a direct current (DC) motor arranged under a wheelchair frame is connected with a speed reducer for driving a transmission shaft; and the composite rear wheel set part is symmetrically arranged at the left side and the right side of a shaft, so that functions of climbing stairs and travelling on the flat ground can be realized. The wheelchair frame is connected with the seat part by a rapidly-dismounted part, so that the whole wheel chair can be arranged in a tail box of a small bus after being rapidly disassembled, and is convenient to carry and transport.

Description

technical field [0001] The invention relates to a new type of transport tool, in particular to an electric wheelchair type stair climbing vehicle. Background technique [0002] With the growth of the human population, our country has entered an aging society at present, but most of the buildings with low floors do not have elevators, which brings inconvenience to the travel of some old, weak, sick and disabled people living upstairs, and even very difficulty. In order to solve the above problems, stair-climbing wheelchairs with star wheel mechanism and stair-climbing wheelchairs with crawler mechanism have appeared in the domestic market, but due to the limitation of manufacturing capacity and technical level, there are certain defects in practicality and cost performance: Stair-climbing wheelchairs with star wheel mechanism are flexible in turning, but the center of gravity fluctuates greatly, poor stability, and poor continuity. Due to the large number of wheels, the whe...

Problems solved by technology

[0002] With the growth of the human population, our country has entered an aging society at present, but most of the buildings with low floors do not have elevators, which brings inconvenience to the travel of some old, weak, sick and disabled people living upstairs, and even very difficulty

In order to solve the above problems, stair-climbing wheelchairs with star wheel mechanism and stair-climbing wheelchairs with crawler mechanism have appeared in the domestic market, but due to the limitation of manufacturing capacity and technical level, there are certain defects in practicality and cost performance: Stair-climbing wheelchairs with star wheel mechanism are flexible in turning, but the center of gravity fluctuates greatly, poor stability, and poor continuity. Due to the large number of wheels, the wheels used are relatively small, so it is difficult to push on sidewalks and brick roads; the crawler mechanism stair-climbing wheelchair goes up and down stairs. Good stability and continuity, but the movement is not flexible enough, the radius of rotation is large, it cannot turn on many floors, and the track is easy to damage the edge of the stairs when climbing stairs

[0003] The performance of the IBOT stair-climbing wheelchair made in the United States is already very good, but when going up and down the stairs, because of the large swing, it is difficult to guarantee the safety of the stairs without the help of others, and because of the high Complicated technologies such as science and technology make the price of this stair-climbing wheelchair as high as more than 30,000 U.S. dollars, so it also limits its market promotion and popularization; A multifunctional electric stair climbing wheelchair that is small, light, easy to operate, good stability, and low in price, has more market potential and social value
