Automatic stair climbing chair

Abstract

The invention discloses an automatic stair climbing chair which comprises an electric folding chair and an electric stair climbing mechanism. The electric folding chair is driven by a servo motor to move forwards or backwards. The electric stair climbing mechanism is arranged on the rear side of the electric folding chair. The electric folding chair and the electric stair climbing mechanism can be folded into a whole to be stored. The electric stair climbing mechanism adopts a pair of caterpillar bands for walking up and down stairs. The electric stair climbing mechanism controls the servo motor through a circuit board and a control box. A spring wire is arranged inside a pull rod, and wiring is performed in a concealed wiring mode. The automatic stair climbing chair is simple in structure, and after the automatic stair climbing chair is folded into the whole, the storage space is small, so that carrying and storage are convenient. Compared with traditional caterpillar bands, plane and longitudinal decoration line caterpillar bands are adopted, and transition is smooth and comfortable; the control wiring is arranged in the concealed wiring mode, wires will not be damaged, and the automatic stair climbing chair is safer; a rear lifting handle has the locking function, so that an operator transfers a patient conveniently; the stair climbing chair is flexible and convenient to operate, safe and stable to use and convenient to maintain.

Description

technical field [0001] The invention relates to the field of wheelchair technical equipment, in particular to an automatic stair climbing chair. Background technique [0002] Wheelchairs have been used for a long time as a means of transportation for the elderly with physical defects or the elderly, weak, sick, disabled, pregnant and other special groups, but when they live in buildings without elevators, they bring great changes to their lives inconvenient. [0003] In the prior art, stair climbing vehicles used with wheelchairs are heavy, inconvenient to fold, and difficult to carry; for example, the utility model patent (CN201079509Y) crawler stair climbing chairs have complex structures, poor stability, are relatively bulky, and have high maintenance costs. Security is not guaranteed. Contents of the invention [0004] In order to solve the above technical problems, the present invention provides an automatic stair climbing chair. Aiming at the deficiencies in the pr...
