Problems solved by technology

The disadvantage of the planetary wheel structure is that the climbing process is discontinuous and intermittent, and the center of gravity fluctuates up and down with the stairs, which brings problems such as safety and comfort during the climbing process; in addition, the structure of the planetary wheel climbing mechanism is complex, Not suitable for promotion
The crawler-type stair-climbing mechanism is currently recognized as an ideal stair-climbing mechanism, but the crawler structure is suitable for special environments such as climbing stairs or crossing obstacles and ditches. Disadvantages of inflexibility

Abstract

The invention discloses a stair climbing cart with automatic switching of wheels and crawlers. The stair climbing cart comprises a rack, two sets of traveling systems and a traveling-system switching device, wherein one set of traveling system is crawler traveling systems, and the other set of traveling system is a driving-wheel traveling system; the traveling modes of the two sets of traveling systems are switched by the traveling-system switching device; the two sides of the rack are provided with the crawler traveling systems; each crawler traveling system comprises a crawler, a crawler driving wheel, a plurality of driven wheels, a swinging wheel, a crawler driving system and a swinging-wheel retracting and extending mechanism; the driving-wheel traveling system comprises an inner rack, a universal wheel, a driving wheel, a universal-wheel retracting and extending mechanism and a driving-wheel driving system; the rack is internally provided with the inner rack and is connected with the traveling-system switching device by the traveling-system switching device; the inner rack can realize switching of the traveling modes under the action of the traveling-system switching device. The stair climbing cart disclosed by the invention has the advantages that the chassis switching is carried out by adopting the two sets of traveling systems and a wheel-crawler switching mechanism; the structure is compact, the switching is convenient, and the functions of climbing stairs, traveling on flat ground and crossing obstacles and ditches are achieved.

Description

technical field [0001] The invention belongs to the field of stair-climbing devices, and relates to a stair-climbing and walking device, in particular to a stair-climbing device with automatic switching of wheels and crawlers. Background technique [0002] At present, when the wheeled mobile device encounters obstacles such as stairs when walking, it often needs to use a special auxiliary climbing device, and the process is very cumbersome. There are two common structures of stair climbing mechanisms: planetary wheel structure and crawler structure. The disadvantage of the planetary wheel structure is that the climbing process is discontinuous and intermittent, and the center of gravity fluctuates up and down with the stairs, which brings about problems such as safety and comfort during the climbing process; in addition, the structure of the planetary wheel climbing mechanism is complex, Not suitable for promotion. The crawler-type stair-climbing mechanism is currently rec...
