Embodiment Construction

[0056] see Figure 4~5 The axle sleeve 1 of the wheel has five spokes 2 evenly distributed on the circular outer surface of the axle sleeve, and the spokes also have arc-shaped track grooves 3; Composed of the skeleton 4, a straight edge of the fan-shaped skeleton is fixed with a limit block 6 matched with the arc track groove; each spoke is fixed on the matching fan-shaped skeleton. The spokes are all on the same plane. Positioning blocks 5 are installed at both ends of the above-mentioned arc track groove. The ends of the spokes are fixed on the same straight edge of the fan-shaped skeleton with the stop block. When the steel ring of the wheel is unfolded, the outline of the steel ring is a figure composed of at least three sail-shaped curves connected end to end. The sail-shaped curve is formed by connecting the upper end of a straight line with one end of an arc, wherein the other end of the arc is connected with the lower end of the second sail-shaped curve, so that th...

Abstract

The invention provides a stair climbing wheel and solves the problems that a gravity center moving curve is not smooth when a conventional transport tool suitable for being used for climbing a stair climbs stairs, and the tool cannot stop power output during a stair-climbing process. The technical scheme is as follows: at least three spokes which are uniformly distributed on the circular outer surface of a shaft sleeve are arranged on the shaft sleeve of the wheel, and arc-shaped track grooves are formed in the spokes; a steel ring is formed by sector-shaped frameworks with the same quantity as that of the spokes; a limiting block matched with an arc-shaped track groove is fixed on one straight side of each sector-shaped framework; and each spoke is fixed on the sector-shaped framework matched with the spoke. The stair climbing wheel has the benefits as follows: the wheel can adapt to the leveled ground as well as a stair type plane; and when the wheel climbs the stairs, the gravity center curve is stable, and the wheel can be stopped and restarted at any time as required. The stair climbing wheel also has the characteristics of extremely high control accuracy, high practicability, low cost and the like.

Description

technical field [0001] The invention relates to the field of smooth movement of stairs, in particular to a stair-climbing wheel that can make a vehicle go up in a smooth curve. Background technique [0002] Stairs are one of the necessary components of modern multi-story and high-rise buildings, and healthy normal people have no hindrance for going up and down stairs. But suffer from disability, infirm old man just will produce a lot of inconvenience when advancing on the stairs. It is also extremely inconvenient when people drag a trolley with heavy objects on the stairs. The main reason is that stairs are an important means of vertical transportation between floors, and the drop is large; . [0003] Existing means of transportation applicable to climbing stairs can be broadly divided into two types. One is a vehicle with multiple wheels and a planetary wheel structure. The center of gravity does not change smoothly during the climbing process, and bumps will still occur...
