Barrier-free passing balance vehicle

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 car suitable for various terrains such as flat ground, stairs, and rough roads. It is mainly used in sports machines such as barrier-free balance wheelchairs, off-road balance cars, and toy balance cars. And control the different inclination angles of the wheel set to adapt to various terrains for free walking and crawling, especially when encountering stairs, the car can automatically control the balance, reduce shaking and bumps, and can realize 360-degree free walking and climbing in the narrow stair platform space. Quickly change the direction of climbing stairs. Background technique [0002] At present, 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 gripping ability of the stairs is not strong; the flat crawler is often used in combination with the crawler and wheel...

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
