Barrier-free self-propelled cart assembly

Abstract

The invention provides a barrier-free self-propelled cart assembly which is provided with horizontal gravity center shifting devices arranged on the two sides of a chassis. Drive units of the horizontal gravity center shifting devices are arranged on the chassis. At least one longitudinal horizontal-moving guide device is arranged on the chassis in the advancing direction of the moving device. Sliding bases matched with the horizontal-moving guide devices are arranged on the power portion of a connecting rack. A sector gear is fixed to one sliding base. A drive motor is fixed to the lower portion of the connecting rack. A motor drive shaft is connected with a gravity center moving transmission gear engaged with the sector gear, and further connected with a horizontal-moving transfer gear box in a transmission mode. The power output shaft of the transfer gear box is axially arranged on the connecting rack in a pivoted mode. Drive gears engaged with racks fixed to a chassis correspondingly are arranged on the power output shaft. The barrier-free self-propelled cart assembly is applied to large-slope road conditions, the gravity center and horizontal balance can be guaranteed, and adverse influence on passengers or cargoes is avoided.

Description

technical field [0001] The invention relates to a mobile device, in particular to a barrier-free self-propelled vehicle assembly. Background technique [0002] When the carrier faces a slope terrain, the carrier will have different center of gravity changes with the ups and downs, the speed of driving and the position of the loaded object (passenger), which is related to the stability, comfort and safety of the vehicle when it travels . [0003] Especially stairs, such architectural structures designed to facilitate normal people to walk up and down hills, have become the biggest nightmare faced by wheeled vehicles. As of today, although there are related inventions and creations for stairs and slope terrains, none of them have been created. It is not ideal, it cannot avoid bumps, shocks, over-inclination...etc., especially the transition between the plane and the slope. Occupants feel uncomfortable or even panic. For the cargo carried, they are prone to displacement and c...

[0003] Especially stairs, such architectural structures designed to facilitate normal people to walk up and down hills, have become the biggest nightmare faced by wheeled vehicles. As of today, although there are related inventions and creations for stairs and slope terrains, none of them have been created. It is not ideal, it cannot avoid bumps, shocks, over-inclination...etc., especially the transition between the plane and the slope. Occupants feel uncomfortable or even panic. For the cargo carried, they are prone to displacement and mutual collision, which seriously cause the vehicle to tilt and overturn
