Electric-control crawler-type stair climbing walking composite vehicle

Abstract

The invention relates to an electric-control crawler-type stair climbing walking composite vehicle. The vehicle comprises a wheelchair seat, front driving wheels, a rear support steering wheel, a frame body, crawler stair climbing mechanisms, a power assembly and a power supply system; the wheelchair seat is arranged on the frame body, the front driving wheels are arranged at the two front sides of the frame body, the rear support steering wheel is arranged at the rear side of the frame body, the crawler stair climbing mechanisms, the power assembly and the power supply system are arranged onthe frame body, and the power assembly is connected with the crawler stair climbing mechanisms to drive the crawler stair climbing mechanisms to run to go upstairs or downstairs. According to the composite vehicle, a hand-pushed wheelchair and the crawler stair climbing mechanisms are combined so that the vehicle can conveniently go upstairs or downstairs for travel application; the vehicle can switch a running mode according to actual needs and flexibly turn, the gravity of the whole vehicle is adjusted when the vehicle goes upstairs or downstairs, and a passenger feels safer.

Description

technical field [0001] The invention relates to an electronically controlled crawler-type stair-climbing and walking compound vehicle, in particular to an electronically-controlled crawler-type stair-climbing and walking compound vehicle used for handicapped and elderly groups as transportation and stair climbing. Background technique [0002] At present, domestic electric stair climbing equipment is mainly divided into two categories: a class is a stair climbing machine (vehicle) based on loading and climbing stairs, and the main form is represented by a wheel type. The other is a stair-climbing machine (vehicle) for assisting people, the main forms of which are star wheel type, crawler type, etc. [0003] my country's current residential housing, 10 years ago, houses with less than 6 floors were mainly without elevators. Moreover, my country has entered a rapidly aging society, and the travel problem of the elderly has become increasingly prominent. In addition, as of 20...
