Embodiment Construction

[0031] Now set forth the present invention in detail in conjunction with accompanying drawing:

[0032] The wheelchair that can climb stairs continuously in this embodiment includes a wheelchair frame 1, a chair seat 2 and casters 5, 6 installed on the front and rear legs 3, 4 of the wheelchair frame, and the tops of the front and rear legs 3, 4 of the wheelchair are connected and mutually rotated and adjusted. The coordination of the angle of intersection, the adjustment of the front and rear foot angles is based on the width of the current stair step surface, so before going up and down the stairs, it is necessary to adjust the front and rear foot angles according to the width of the stairs. In order to facilitate the operation of the operator, a Left and right handles 21, 22 are arranged, and each handle is provided with a button switch. One button switch is responsible for controlling the action of going up stairs, and the other button switch is responsible for controlling ...

Abstract

The invention discloses a wheelchair capable of climbing stairs continuously. The wheelchair comprises a wheelchair frame, a seat, and trundles arranged on front and rear feet of the wheelchair frame, wherein a turning wheel is movably and rotatably bolted on the wheelchair frame and above a rotating shaft of each trundle; a climbing arm is fixedly arranged on each turning wheel; the lowest point in a rotating track of the tail end of each climbing arm is lower than the lowest point of each trundle; and the turning wheels are matched in a synchronous rotation way. With adoption of the technical scheme, the climbing arms can perform unidirectional and continuous climbing actions by utilizing the continuous rotation of the turning wheels, so that the efficiency of stair climbing is enhanced; and compared with a stair climbing wheelchair in background technology, the wheelchair disclosed by the invention is more simplified in structure, and electric control can be realized in the whole course of the wheelchair, so that a feeble and sick patient can operate the wheelchair well.

Description

Technical field: [0001] The invention relates to a wheelchair capable of continuously climbing stairs. Background technique: [0002] The application number is 201120421944.8, and the name is "a wheelchair that can climb stairs". Although the stair climbing wheelchair mentioned in the invention patent application document has good stability and labor-saving lever device, its structure is very complicated. It is necessary to push and pull the rocker of the one-way flywheel hand crank back and forth to rotate the first rotating rod. First, let the rotating foot support end of the wheelchair tilt up, push the wheelchair forward until the rotating foot support end is placed on the next step, and reciprocate Push and pull the rocker of the one-way flywheel hand crank, the first rotating rod rotates, driving the first rope to pull the rotating foot to rotate, thereby propping up the entire wheelchair, and then the wheelchair needs to be manually pushed forward until the wheelchair...
