Abstract

The invention discloses an electric stair climbing wheelchair, and belongs to the field of medical instruments, and aims at helping people who cannot move easily go upstairs and downstairs stably. In the whole mechanism, a five-bar mechanism is employed as the core technology, an electric pushing cylinder is equipped as the auxiliary support, The electric stair climbing wheelchair is small and portable, and is high in adaptability, stable to operate and high in safety, and can operate in a narrow passageway. A patient sits on the chair, under the control of an operator, power is transmitted to the five-bar mechanism through a motor and a transmission mechanism, by combining the support effect of the electric pushing cylinder, the electric stair climbing wheelchair is lifted up and conveyed to a last step or a next step, and functions of going-upstairs and going-downstairs are achieved.

Description

technical field [0001] The patent of the present invention relates to a wheelchair, in particular to a wheelchair for climbing stairs. Background technique [0002] The invention is a novel electric wheelchair for climbing stairs. There are two common types of existing stair-climbing wheelchairs: star-wheel type and crawler-type. The star-wheel type stair-climbing wheelchair has a fixed star wheel track and depth, and the height and width of the stairs are different, so misalignment and slippage are prone to occur during crawling. Phenomena, there are certain safety hazards; crawler-type stair-climbing wheelchairs, when the crawler leaves the previous step or travels to the next step, it will tilt forward and backward due to the deviation of the center of gravity, especially on the first or last step. Stair climbing wheelchairs are not suitable for use on occasions where the steps of the stairs are too smooth and the slope is greater than 30-35 degrees, and the crawler stai...
