Barrier-free balance car

Abstract

The invention discloses a safe and convenient barrier-free passing balance vehicle. The balance vehicle can adapt to various terrains such as flat grounds, stairways, bumpy roads and the like. The balance vehicle is mainly composed of four controllable rotating composite wheels and a vertical balance vehicle body frame, wherein composite wheels comprise walking wheels, tracks and Mecanum wheels; the walking wheels are for normal roads; the combination of the walking wheels and the tracks is adopted on uneven roads; and the combination of the Mecanum wheels and the tracks is adopted on stairways; and a vehicle body can be constantly kept vertically balanced via the vehicle body frame on the basis of the changing principle of interiors angles of parallelogram. The vehicle can be independently operated; before walking, proper wheel combinations and corresponding inclination angles of the composite wheels are selected in accordance with road conditions; during walking, the vehicle can be automatically kept balanced and can be automatically adjusted in accordance with road conditions; therefore, the vehicle is stable and comfortable in running; and the vehicle, in particular in climbingstairs, is simple to operate, and climbing directions can be rapidly changed, so that continuous, stable and rapid climbing can be achieved.

Description

Technical field [0001] The patent of the present invention relates to a barrier-free balance vehicle adapted to various terrains such as flat ground, stairs, rugged roads, etc. It is mainly used for barrier-free balance wheelchairs, cross-country balance vehicles, toy balance vehicles and other sports machines, through the transformation of wheel sets And control the different inclination angles of the wheels to adapt to various terrains to walk and crawl freely, especially when encountering stairs, the car can automatically control the balance, reduce jitter and bumps, and achieve 360-degree free walking and walking in the narrow stair platform space. Change the direction of climbing quickly. Background technique [0002] At present, the known barrier-free vehicles mainly include wheeled, flat crawler, and two-stage or three-stage segmented crawler. The wheeled walking process is jittery and the stairs are not strong enough; the flat track is often used in combination with the ...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the disadvantages of the existing barrier-free vehicles that require external force, unsteady operation, cumbersome operation, and low crawling efficiency, the patent of the present invention provides a barrier-free balance vehicle, which can not only walk freely on flat ground, but also Steering, and when walking up and down stairs or on uneven roads, without external human assistance, it can automatically maintain balance and run smoothly and comfortably. Especially on narrow roads or stair platforms, it can simply and quickly change the direction of climbing stairs, eliminating the need for stair platforms. The cumbersome operation that needs to reverse the direction of climbing stairs
